SFEG Common Stock.

Effect on SFEG Common Stock.

At the Effective Time, subject to the other provisions of this ARTICLE 2 and Section 3.1, each share of SFEG Common Stock (other than shares of SFEG Common Stock held in the treasury of SFEG or held by IGS ) issued and outstanding immediately prior to the Effective Time will, by virtue of the Merger and without any action on the part of the holder thereof, be cancelled in exchange for the right to receive 12 ###-###-#### (the "Exchange Ratio") ordinary shares of IGS (“IGS Common Share”). Upon the effectiveness of a “10-for-1 consolidation” of IGS Common Shares, in accordance with Section 2.1(a)(ii), the Exchange Ratio will be adjusted to 1.23254627. All IGS Common Shares shall be delivered to the holders of SFEG Common Stock in the form of American Depositary Receipts (“IGS ADR’s”) shares, each representing the right to receive twenty (20) IGS Common Shares, or such other number of shares as IGS and SFEG may mutually determine to be the optimum bundle of IGS shares (the "IGS ADSs"). The IGS ADSs may be evidenced by one or more receipts ("IGS ADRs") issued in accordance with the Deposit Agreement, to be entered into among IGS, The Bank of New York Mellon Corporation (or other mutually agreeable depositary bank), as Depositary (the "Depositary"), and the holders from time to time of IGS ADRs, as may be amended and restated as of the date on which the Effective Time occurs (the "Deposit Agreement").

In the event that, subsequent to the date of this Agreement but prior to the Effective Time, the outstanding IGS Common Shares or shares of SFEG Common Stock are changed into a different number of shares or a different class as a result of a consolidation, stock split, reverse stock split, stock dividend, subdivision, reclassification, combination, exchange, recapitalization or similar transaction, the Exchange Ratio will be adjusted appropriately.

Notwithstanding the provisions of Section 2.1(a), no fractional IGS ADSs will be issued pursuant to the Merger. In lieu of the issuance of fractional IGS ADSs, cash payments in United States dollars will be made to the former holders of SFEG Common Stock with respect to any fractional IGS ADS that would otherwise be issuable pursuant to the Merger in an amount equal to such fractional part of a IGS ADS multiplied by the United States dollar equivalent of the closing price of the IGS Ordinary Shares underlying the ADSs on the ASX on the last trading day preceding the Closing Date. The calculation of the United States dollar equivalent of such closing price will be based on the arithmetic mean of the buy and sell spot rates of exchange for Australian dollars and United States dollars on the London market at 11:00 a.m., London time, on the last trading day in London preceding the Closing Date. No such holder will be entitled to dividends, voting rights or any other shareholder right with respect to any fractional IGS ADSs that such holder, but for the provisions of this Section 2.1(a)(iii), would be entitled to receive pursuant to the Merger. For purposes of this Section 2.1(a)(iii), shares held of record by a particular stockholder of SFEG and represented by two or more share certificates may be aggregated in order to reduce the fractional IGS ADSs issuable to such stockholder.

The IGS ADSs to be issued upon the conversion of shares of SFEG Common Stock pursuant to Section 2.1(a)(i) and the cash to be paid in lieu of fractional IGS ADSs pursuant to Section 2.1(a)(iii) are referred to in this Agreement collectively as the “Merger Consideration”.

Notwithstanding the other provisions of this Section 2.1, where IGS reasonably determines that the issue of IGS ADSs in the jurisdiction of a relevant proposed recipient of IGS ADSs (other than recipients resident in the United States or any jurisdiction to which IGS ADSs may be issued pursuant to exemptions from the registration and prospectus delivery requirements applicable to public offerings of securities to persons in such jurisdictions) is either prohibited or unduly onerous or impracticable (each such proposed recipient, an “Ineligible Overseas Stockholder”), IGS will procure that the Sale Agent will be issued such number of IGS ADSs as are attributable to the Ineligible Overseas Stockholders as Merger Consideration and will further procure that such IGS ADSs are sold and the proceeds of sale paid to the Ineligible Overseas Stockholders as soon as reasonably practicable after the Effective Time. The term “Sale Agent” as used in this Agreement means the person nominated by IGS to sell the IGS ADSs that are attributable to the Ineligible Overseas Stockholders under the terms of this Agreement.

No Further Rights. All of the shares of SFEG Common Stock converted into the right to receive Merger Consideration pursuant to this ARTICLE 2 automatically will no longer be outstanding, will be cancelled, and will cease to exist. Each holder of (x) a certificate (each a “Certificate”) previously representing any such shares of SFEG Common Stock or (y) non-certificated shares of SFEG Common Stock represented by book entry (“Book-Entry Shares”) will thereafter cease to have any rights with respect to such shares of SFEG Common Stock, except, to the extent provided herein, the right to receive Merger Consideration in accordance with the terms hereof.

Effect on SFEG Options; SFEG Warrants and SFEG Convertible Debentures.

Unless exercised, cancelled, exchanged, or terminated pursuant to a SFEG Option Contract, any SFEG Option outstanding at the Effective Time will remain outstanding immediately after the Effective Time, unless and until exercised, cancelled, exchanged, or terminated. Unless exercised, cancelled, exchanged, or terminated pursuant to a SFEG Warrant Contract, any SFEG Warrant outstanding at the Effective Time will remain outstanding immediately after the Effective Time, unless and until exercised, cancelled, exchanged, or terminated in accordance with its terms. Unless exercised, cancelled, exchanged, or terminated pursuant to a SFEG Convertible Debenture, any SFEG Convertible Debenture outstanding at the Effective Time will remain outstanding immediately after the Effective Time, unless and until exercised, cancelled, exchanged, or terminated in accordance with its terms.

In SFEG’s sole discretion, SFEG may permit each outstanding stock option to acquire shares of SFEG Common Stock (each, a “SFEG Stock Option”) granted under the SFEG 2007 Equity Incentive Plan and any other current or former stock option plan, program, agreement or arrangement of SFEG (collectively, the “SFEG Stock Plans”) to be converted at the Effective Time into an option to purchase IGS ADSs in accordance with a procedure which satisfies the requirements under Section 424(a) of the Code; provided that to the extent consistent with satisfying such requirements, each SFEG Stock Option will be converted into an option to purchase that whole number of IGS ADSs that could have been obtained upon the exercise of such SFEG Stock Option immediately prior to the Effective Time and the conversion and exchange of the shares of SFEG Common Stock issued upon such exercise for IGS ADSs as provided in Section 2.1, and the exercise price per share applicable to each such SFEG Stock Option will be adjusted at the Effective Time as appropriate so as to preserve with respect to each option to purchase IGS ADSs the excess of the fair market value of each share of IGS Common Stock subject to the corresponding SFEG Stock Option immediately before the Effective Time over the option price for such share of SFEG Common Stock.

At the Effective Time, each share of SFEG Common Stock, if any, issued pursuant to any SFEG Stock Plan that is subject to transfer limitations or vesting provisions under the terms of such SFEG Stock Plan, or under any individual grant agreement pursuant to which such SFEG Common Stock was issued or any other agreement between SFEG and the holder thereof, will upon conversion thereof into a IGS ADS pursuant to the Merger continue to be subject to the same transfer limitations and vesting provisions, except as specifically provided in the SFEG Stock Plans. Any cash which would have been payable under Section 2.1(a)(iii) will be paid to the holder of such SFEG Common Stock without regard to any such transfer limitations or vesting provisions.

The board of directors or compensation committee of SFEG and IGS will grant all approvals and take all other actions reasonably required pursuant to Rule 16b-3(e) under the Securities Exchange Act of 1934, as amended (together with the rules and regulations of the Securities and Exchange Commission (the “SEC”) thereunder, the “Securities Exchange Act”) (and the ASX Listing Rules (is applicable)), to cause the disposition in the Merger of SFEG Common Stock and SFEG Stock Options held by affiliates of SFEG to be exempt from the provisions of Section 16(b) of the Securities Exchange Act.

Effect on Merger Sub Stock.

At the Effective Time, each share of common stock, par value $0.002 per share, of Merger Sub then issued and outstanding will, by virtue of the Merger and without any action on the part of IGS, Merger Sub, SFEG, or the holder thereof, be converted into and become one fully paid and nonassessable share of common stock, par value $0.002 per share, of the Surviving Corporation.

Provision of Merger Consideration.

IGS Obligations.

Prior to the Effective Time, IGS shall enter into an exchange agent agreement, in form and substance reasonably satisfactory to SFEG (the “Exchange Agreement”), with the Exchange Agent to act as agent for the facilitation of the surrender or transfer of Certificate or Book-Entry Shares formerly representing shares of SFEG Common Stock and otherwise to comply with the procedures set forth in this ARTICLE 3.

At the Effective Time and based on the shareholder registry records of SFEG and its transfer agent, as provided by SFEG to IGS, IGS shall cause the Exchange Agent to issue and allot to each Record Holder the Merger Consideration as that Record Holder is entitled to receive.

As soon as reasonably practicable following the Effective Time, IGS shall mail to each Record Holder a holding statement setting forth the aggregate number of IGS Shares issued to such Record Holder under Section 3.1(a)(ii).

Exchange Procedures.

Promptly after the Effective Time, and in any event not later than the second Business Day following the Effective Time, IGS shall direct the Exchange Agent, pursuant to the Exchange Agreement, to mail to each holder of record of a Certificate or Book-Entry Share formerly representing shares of SFEG Common Stock: (1) a letter of transmittal (each, a “Letter of Transmittal”), which must (A) specify that delivery will be effected, and risk of loss and title to such shares will pass, only upon proper delivery or transfer of such shares to the Exchange Agent and (B) be in customary form and subject to the reasonable approval of SFEG prior to the Effective Time; and (2) instructions for effecting the surrender or transfer of such Certificate or Book-Entry Share in exchange for the Merger Consideration payable in respect of the shares of SFEG Common Stock represented by such Certificate or Book-Entry Share.

Upon (1) in the case of SFEG Common Stock represented by a Certificate, surrender of such Certificate for cancellation to the Exchange Agent in accordance with this Section 3.1(b), together with the return of the applicable Letter of Transmittal, properly completed and duly executed, and such other documents as might be required pursuant to the instructions set forth in such Letter of Transmittal or (2) in the case of SFEG Common Stock represented as a Book-Entry Share, receipt of an “agent’s message” by the Exchange Agent (or such other evidence, if any, of transfer as the Exchange Agent might reasonably request), and such other documents as might be required pursuant to the instructions set forth in the applicable Letter of Transmittal, the holder of such Certificate or Book-Entry Share, as the case might be, will thereby be entitled to receive in exchange therefore one or more IGS ADSs representing, in the aggregate, the whole number of IGS ADSs, if any, that such Holder has the right to receive pursuant to Section 2.1(a) (after taking into account all shares of SFEG Common Stock then held by such holder).

Promptly after receipt or notification by the Exchange Agent of the surrender or transfer in accordance with Section 3.1(b)(ii), the Exchange Agent will notify IGS and IGS shall then send or procure the dispatch to each Holder, by pre-paid post to his or her address recorded with SFEG at the Effective Time, a holding statement or notice confirming the issue of IGS ADSs to that Holder representing the total number of ADSs to be issued to that Holder in accordance with ARTICLE 2 and this ARTICLE 3.

No interest will be paid or accrue on any Merger Consideration that is payable to holders of Certificates or Book-Entry Shares.

If there is a transfer of ownership of shares of SFEG Common Stock prior to the Effective Time that is not registered in the transfer records of SFEG, then the Merger Consideration payable in respect of such shares of SFEG Common Stock is to be issued or paid to the applicable transferee if (1) the Certificate representing such shares of SFEG Common Stock is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer, and (2) the Person requesting such exchange pays to the Exchange Agent in advance any transfer or other taxes required by reason of the delivery of the Merger Consideration in any name other than that of the registered holder of the Certificate surrendered, or required for any other reason, or establishes to the satisfaction of the Exchange Agent that such tax has been paid or is not payable.

Until surrendered or, in the case of any Book-Entry Share, transferred, as contemplated by this Section 3.1(b), each Certificate or Book-Entry Share will be deemed at any time after the Effective Time to represent only the right to receive upon such surrender or transfer the Merger Consideration payable in respect of the shares of SFEG Common Stock represented by such Certificate or Book-Entry Share.

Distributions with Respect to Unexchanged IGS ADSs. No dividends or other distributions declared or made after the Effective Time with respect to IGS ADSs with a record date after the Effective Time will be paid to the holder of any Certificate that has not been properly surrendered or Book-Entry Share that has not been properly transferred with respect to IGS ADSs that such holder would be entitled to receive upon proper surrender of such Certificate or transfer of such Book- Entry Share; except that, following the surrender of any such Certificate or transfer of any such Book-Entry Share, IGS shall pay to such holder of IGS ADSs issuable in exchange therefor, without interest, (i) the amount of dividends or other distributions with a record date after the Effective Time theretofore paid with respect to such IGS ADS, and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to such surrender or transfer and a payment date subsequent to such surrender or transfer payable with respect to such IGS ADS. For purposes of dividends or other distributions in respect of IGS ADSs, all ADSs to be issued pursuant to the Merger will be entitled to dividends or other distributions pursuant to the immediately preceding sentence as if such IGS ADSs were issued and outstanding as of the Effective Time.

No Further Rights in SFEG Common Stock. The Merger Consideration issued upon conversion of a share of SFEG Common Stock in accordance with the terms hereof will be deemed to have been issued in full satisfaction of all rights pertaining to such share of SFEG Common Stock.

No Liability. None of IGS, SFEG, the Surviving Corporation, the Exchange Agent, or any other Person will be liable to any former holder of shares of SFEG Common Stock for any IGS ADSs (or dividends or distributions with respect thereto) delivered to a public official pursuant to any abandoned property, escheat or similar Law.

Lost Certificates. If any Certificate is lost, stolen, or destroyed (any such Certificate, a “Lost Certificate”) and the Person claiming such Lost Certificate to be lost, stolen, or destroyed signs and delivers to the Exchange Agent an affidavit of that fact and, if required by IGS, such Person posts a bond (in such reasonable amount as IGS directs) as indemnity against any claim that might be made against the Exchange Agent, IGS, or the Surviving Corporation with respect to such Lost Certificate, then the Exchange Agent will so notify IGS, and IGS will issue, in exchange for such Lost Certificate, the Merger Consideration payable in respect of the shares of SFEG Common Stock represented by such Lost Certificate without any interest thereon.

Withholding. Each of IGS, the Surviving Corporation, and the Exchange Agent are entitled to deduct and withhold from the consideration otherwise payable pursuant hereto to any Holder such amounts as are required to be deducted and withheld under any provision of any Law relating to Taxes with respect to the making of such payment or otherwise in connection with the transactions contemplated hereby, including Section 2.1(a)(ii). Such withheld amounts are to be treated for all purposes hereof as having been paid to such Holder.

IGS and, where applicable, IGS, shall comply, and IGS shall cause IGS Subsidiaries to comply, with the following:

During the Pre-Closing Period, IGS shall operate IGS Business in accordance with an interim operating plan as mutually agreed upon by IGS and SFEG (the “Operating Plan”).

(1) SFEG and IGS shall each appoint and designate one of their respective executive or managing employees as the liaison officers to oversee and assist in the management of the business of IGS during the Pre-Closing Period (the “Liaison Officer”), with powers and authority as set forth herein. SFEG hereby appoints and designates W. Pierce Carson as the initial Liaison Officer.

The Liaison Officer will be available at all reasonable times to communicate, confer and work directly with IGS’s Chief Executive Officer, and with other IGS employees as appropriate and as directed by IGS’s Chief Executive Officer, and the Liaison Officer will also communicate directly with and respond to communications and requests from IGS Board (or a designated IGS Board Committee) with regard to the management and operations of IGS and the Transactions.

Without limiting IGS’s obligations under Section 6.15, during the Pre- Closing Period, IGS shall use its Reasonable Best Efforts to timely comply with all applicable filing and other requirements of the SEC and NYSE MKT.

During the Pre-Closing Period, IGS, with the cooperation and support of SFEG, will use its Reasonable Best Efforts to seek and raise sufficient equity capital or other financing (whether through offerings by SFEG or by means of capital funding support provided to SFEG by IGS to the extent provided in the immediately following sentence, or any combination thereof) to meet SFEG’s liquidity and working capital requirements, and, to the extent necessary, to have at least $10,000,000 in cash securities on hand at the Closing (assuming a Qualified Equity Financing is completed for a minimum of A$5,000,000 and less any funds provided to SFEG in accordance with Section 6.1(e)).

For avoidance of doubt, and notwithstanding IGS’s obligations under Section 6.1(a) and 6.1(b), the terms of the Operating Plan and the provisions of Section 6.1(c), the business and affairs of IGS shall remain under the direction of IGS Board (or a designated IGS Board Committee). Notwithstanding the provisions of Section 6.1(b), in the event that SFEG Board (or a designated SFEG Board Committee) determines that it is necessary in order to exercise and comply with SFEG Board’s fiduciary duties under applicable Law and preserve the continued viability of SFEG, then SFEG is permitted to issue and sell shares of capital stock (or securities convertible into or exchangeable for shares of capital stock [in SFEG]) subject to the consent of IGS (which must not be unreasonable withheld)

During the Pre-Closing Period (and subject to completion of the Qualified Equity Financing unless otherwise agreed by IGS), IGS shall advance to SFEG such reasonable amounts as SFEG may reasonably request, including amounts such necessary amounts raised in connection with the Qualified Equity Financing, as agreed by the parties (collectively, the “Bridge Loan”); provided, however, that before any amounts share advanced by IGS to SFEG under the Bridge Loan, SFEG shall deliver to IGS: (i) letters from stockholders of SFEG, representing at least 30 percent of the outstanding shares of SFEG Common Stock, indicating the holders’ respective support for the Merger and intent to vote in favour thereof, (ii) a security agreement, in substantially the same form as the security agreement relating to the Senior Secured Notes, granting IGS a third lien security interest (or such higher security lien behind previously disclosed existing creditors) in all of SFEG’s assets, other than other than SFEG’s legal and beneficial rights in the lease between SFEG and Ortiz Mines Inc. dated August 1, 2004, as amended on May 1, 2010 and the real property which is subject to such lease, (or in the case that SFEG debt is repaid that IGS will assume the security held by that debtor), and (iii) a promissory note, in substantially the same form as the Senior Secured Notes in the original principal amount of the amounts advanced under the Bridge Loan.

Access to Information and Properties.

Upon reasonable notice and subject to applicable Laws relating to the exchange of information, each of SFEG and IGS (as the case might be, the “Permitting Party”) shall, and shall cause each of its Subsidiaries to, afford to the authorized representatives of the other Party (such other Party, the “Accessing Party”), including officers, employees, accountants, counsel, and other representatives of the Accessing Party, at the Accessing Party’s sole expense, reasonable access, during normal business hours during the Pre-Closing Period, to all of the Permitting Party’s properties (including owned or leased real property), Contracts, books, records, data, and personnel and, during the Pre-Closing Period, the Permitting Party shall, and shall cause Permitting Party’s Subsidiaries to, make available to the Accessing Party all information concerning the Permitting Party’s business, properties, and personnel as the Accessing Party might reasonably request. Each Accessing Party shall not access and shall not review the foregoing information in a manner that interferes unreasonably with the operations of the Permitting Party or the Permitting Party’s Subsidiaries or that unreasonably interferes with the prompt discharge by the Permitting Party’s employees of their duties. Representatives of the Accessing Party (including, in the case of IGS, IGS Liaison Officer), when visiting the premises of the Permitting Party, will at all times conduct themselves in accordance with applicable local law and the reasonable policies and procedures of the Permitting Party.

Each of SFEG and IGS (as the case might be, the “Indemnifying Party”) shall indemnify and hold harmless the other Party and the other Party’s Subsidiaries (such other Party and such other Party’s Subsidiaries, collectively, the “Indemnified Parties”) from any and all Claims and Liabilities, including costs and expenses for the injury to or death of any of the Indemnified Party’s representatives and any loss or destruction of any property (including Claims or Liabilities for use of any property) resulting directly or indirectly from the action or inaction of any of the Indemnifying Party or the Indemnifying Party’s Subsidiaries, or their respective representatives, as applicable, during any visit to the business or property of the Indemnifying Party prior to the completion of the Merger (whether pursuant to Section 6.2(a) or otherwise), other than any such Claims and Liabilities arising out of or resulting from the negligence or willful misconduct of the representatives of the Indemnified Party or the Indemnified Party’s Subsidiaries. Each Indemnified Party is hereby made a third-party beneficiary of the rights that would be afforded under this Section 6.2(b) to such Indemnified Party as if such Indemnified Party were an original signatory hereto for such purposes (and only for such purposes).

During the Pre-Closing Period, SFEG shall, and shall cause each SFEG Subsidiary to, at the request of IGS or IGS’s representatives, (i) request such SFEG Entity’s customers, suppliers, lenders, and other creditors to be available to meet with IGS and IGS’s representatives and (ii) cooperate with IGS and IGS’s representatives in connection with such meetings and use Reasonable Best Efforts to facilitate such meetings.

A Party will not be required to provide access to or to disclose information (and will not be required to cause such Party’s Subsidiaries to provide access to or to disclose information) if such access or disclosure would violate or prejudice the rights of such Party’s customers, jeopardize any attorney-client privilege, or contravene any Law or any binding Contract entered into prior to the Signing Date. If such a circumstance arises, then SFEG and IGS shall make reasonable and appropriate substitute disclosure arrangements under circumstances in which the restrictions of the preceding sentence apply.

During the Pre-Closing Period, SFEG shall grant IGS Liaison Officer full access to SFEG headquarters’ offices, and any other real property that any SFEG Entity leases as IGS Liaison Officer reasonably requests, and all SFEG books, records, and personnel during normal business hours, and shall permit IGS to host authorized IGS representatives at SFEG headquarters’ offices, including engineers, advisors and consultants, and lenders and financing sources, at IGS’s sole risk and expense (subject to Section 6.2(b)) and without unreasonably disrupting SFEG operations, in order to investigate and assess the management of any SFEG Entity, as IGS reasonably deems necessary or appropriate (a “IGS Investigation”). SFEG shall (and shall cause each SFEG Subsidiary to) cooperate with IGS in conducting any such IGS Investigation and, (ii) allow IGS full access to SFEG Entities’ respective businesses, SFEG Real Property, and SFEG Assets.

Notwithstanding anything in this Section 6.3 to the contrary, (i) no Party is obligated under Section 6.3 to disclose to any other Party or such other Party’s representatives, or grant such other Party or such other Party’s representatives access to, information that is within the possession or control of such first Party or such first Party’s Subsidiaries but that is not permitted to be disclosed to such other Party or such other Party’s representative pursuant to a binding confidentiality agreement with a third party without first obtaining the consent of such third party, and such other Party, to the extent requested by such first Party, shall use such other Party’s Reasonable Best Efforts to obtain any such consent.

No investigation by any Party or such Party’s representatives will (or will be deemed to) modify or constitute a waiver of any of the terms hereof (including any representation, warranty, obligation, acknowledgment, or condition hereunder).

Capital Raise By SFEG.

Each Party acknowledges and agrees that during the Pre-Closing Period SFEG may (a) issue up to an additional US$5.0 million in equity or debt securities or (b) refinance any of its outstanding debt. Any such equity or debt offering during the Pre-Closing Period will be done by SFEG in consultation with IGS. SFEG and IGS shall use their commercial reasonable efforts to complete such financing in a manner so as to not revoke the IGS Shareholder approvals obtained at the Annual General Meeting in 23 November 2012.

Further Action; Reasonable Best Efforts.

Subject to the terms hereof, each Party shall use such Party’s Reasonable Best Efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper, or advisable under applicable Laws to consummate and make effective the Transactions, including using Reasonable Best Efforts to satisfy the conditions set forth in ARTICLE 7, to obtain, give, or make all necessary Consents, and to effect all necessary registrations and filings. Subject to the terms hereof, each Party shall furnish to the other Parties such necessary information and reasonable assistance as such other Parties reasonably request in connection with the foregoing, and shall provide the other Parties with copies of all filings made by such Party with any Governmental Entity or any other information supplied by such Party to a Governmental Entity, in each case that are filed or supplied in connection herewith.

Subject to the terms hereof, each Party shall (i) take all actions necessary to ensure that no state takeover Law or similar Law is or becomes applicable to the Transactions and (ii) if any state takeover Law or similar Law becomes applicable to the Transactions, take all action necessary to ensure that the Transactions can be consummated as promptly as practicable on the terms contemplated hereby and otherwise to minimize the effect of such Law on the Transactions.

Subject to the terms hereof, each Party shall use such Party’s Reasonable Best Efforts to prevent the entry of, and to cause to be discharged, vacated, or terminated, any order, decree, ruling, or injunction precluding, restraining, enjoining, delaying, or prohibiting consummation of the Merger. If any Governmental Entity issues any such order, decree, ruling, or injunction, or takes any other action that would have the effect of precluding, restraining, enjoining, delaying, or otherwise prohibiting the consummation of the Transactions, then, subject to the terms hereof, each Party shall use such Party’s Reasonable Best Efforts to have such order, decree, ruling, or injunction or other action declared ineffective as soon as practicable.

Each Party shall (i) give each other Party reasonable advance notice of all meetings with any Governmental Entity relating to the Merger, (ii) give each other Party (or such other Party’s outside counsel) an opportunity to participate in each of such meetings, (iii) provide each other Party with a reasonable advance opportunity to review and comment upon all written communications (including any analyses, presentations, memoranda, briefs, arguments, opinions, and proposals) to or with a Governmental Entity relating to the Merger, and (iv) promptly provide each other Party with copies of all written communications to or from any Governmental Entity relating to the Merger.

Notwithstanding the foregoing provisions of this Section 6.4, no IGS Entity is hereby required to divest or hold separate or in trust (or submit to the imposition of any other conditions or restriction with respect to) any assets or operations of such IGS Entity or any of such IGS Entity’s Affiliates or of any SFEG Entity.

Proxy Statement; Form F-4; Stockholders’ Meeting.

As promptly as practicable after the execution and delivery hereof, the Parties shall cooperate in preparing and filing with the SEC, in connection with the Merger, a proxy statement (together with any amendments or supplements thereto, the “Proxy Statement”), the F-4 (in which the Proxy Statement will be included as a prospectus), and, if necessary, any other statement or schedule relating to this Agreement or the Transactions (each of the Proxy Statement, the F-4, and each such other statement or schedule, an “SEC Transaction Document”). Each Party shall use such Party’s Reasonable Best Efforts to furnish the information required to be included by the SEC in any SEC Transaction Document. Each Party shall give the other Parties and their respective counsel a reasonable opportunity to review and comment on the SEC Transaction Documents, including all amendments and supplements thereto, prior to such SEC Transaction Documents being filed with the SEC or disseminated to SFEG Common Stock Holders, and shall also give the other Parties and such counsel a reasonable opportunity to review and comment on all responses to requests for additional information and comments received from the SEC prior to revisions to such SEC Transaction Documents being filed with, or sent to, the SEC. Each Party shall use such Party’s Reasonable Best Efforts to cause the F-4 to be declared effective under the Securities Act as promptly as practicable after such filing, and SFEG shall as promptly as practicable after the F-4 is declared effective mail the Proxy Statement to SFEG Capital Stock Holders.

If at any time prior to the Effective Time, any Party discovers any event or circumstance relating to any Party or any of such Party’s Affiliates, or any of such Party’s or such Affiliate’s officers or directors, that should be set forth in an amendment to the F-4 or a supplement to the Proxy Statement or other SEC Transaction Document, such Party shall promptly inform the other Parties thereof in writing, and the Parties shall cooperate in preparing and filing such amendment or supplement with the SEC, shall use their respective Reasonable Best Efforts to cause such amendment or supplement to become effective (if applicable) as promptly as possible, and, if necessary, shall mail such amendment or supplement to SFEG Capital Stock Holders. Each Party shall ensure that all documents that such Party is responsible for filing with the SEC in connection with the Transactions complies as to form in all material respects with applicable requirements of the Securities Act and the Exchange Act.

SFEG, acting through SFEG Board, shall, in accordance with its certificate of incorporation and bylaws, the rules and regulations of NYSE MKT, and applicable Law, promptly and duly call, give notice of, convene, and hold, as soon as practicable following the date upon which the F-4 becomes effective (and in no event later than 45 days after such date), a meeting of SFEG Capital Stock Holders for the sole purpose of considering and taking action upon this Agreement (such meeting, including any reconvened meeting held following any postponement or adjournment thereof, the “Stockholder Meeting”), and shall, except as otherwise provided in Section 6.2(c), (d), or (g), (i) recommend adoption hereof (the “SFEG Board Recommendation”) and include in the Proxy Statement such recommendation and (ii) use SFEG’s Reasonable Best Efforts to solicit and obtain such adoption and approval. Notwithstanding any Adverse Recommendation Change or the commencement, public proposal, public disclosure, or communication to SFEG of any Acquisition Proposal, or any other fact or circumstance, SFEG, acting through SFEG Board, shall submit this Agreement to SFEG Capital Stock Holders at the Stockholder Meeting for the purpose of adopting this Agreement, with such disclosures as are required to be made by applicable Law; except that (x) any such statement or disclosure made that relates to an Acquisition Proposal will be deemed to be an Adverse Recommendation Change unless SFEG Board reaffirms SFEG Board Recommendation in such statement or disclosure (except that a mere “stop, look and listen” disclosure in compliance with Rule 14d-9(f) of the Exchange Act will not be deemed to constitute an Adverse Recommendation Change), and (y) SFEG shall not present for approval or adoption any Acquisition Proposal to SFEG Capital Stock Holders at the Stockholder Meeting. Following any such Adverse Recommendation Change, SFEG is permitted to submit this Agreement to SFEG Capital Stock Holders without a recommendation or with a negative recommendation, in which event SFEG Board is permitted to communicate the basis for its lack of a recommendation or negative recommendation to SFEG Capital Stock Holders in the Proxy Statement or an appropriate amendment or supplement thereto.

As promptly as practicable after the execution and delivery hereof, SFEG shall provide to IGS (in such reasonable form requested by IGS), all information regarding SFEG Entities and SFEG securities that is required by the Corporations Act, the ASX Listing Rules, and all regulatory guides of the Australian Securities and Investments Commission application to the Transactions.

SFEG shall ensure that the Proxy Statement and the F-4 comply as to form in all material respects with the provisions of the Exchange Act and the Securities Act, except that SFEG will have no liability with respect to statements made in the F-4 or in the Proxy Statement to the extent that such statements are based on information supplied by any IGS Entity for inclusion in the Proxy Statement or the F-4, respectively. SFEG shall ensure that none of the information that SFEG supplies that is ultimately included or incorporated by reference in any IGS Shareholder Meeting Notice of Meeting or in any document lodged with the ASX or filed with any Governmental Entity will contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they are made, not misleading.

IGS shall ensure that IGS Shareholder Notice of Meeting and documents to be lodged with the ASX will comply as to form in all material respects with the provisions of the listing rules of the ASX, Corporations Act, as applicable, except that no IGS Entity will have any liability with respect to statements made in IGS Shareholder Notice of Meeting or documents to be lodged with the ASX to the extent that such statements are based on information supplied to any IGS Entity by SFEG for inclusion in IGS Shareholder Notice of Meeting or such documents.

Notification of Certain Matters.

Each Party shall promptly notify each other Party if at any time (a) any representation or warranty made by such Party hereunder would be untrue or inaccurate in any material respect if made at such time (without regard as to whether such representation or warranty expressly relates to the Signing Date) or (b) such Party fails to comply with or satisfy in any material respect any obligation to be complied with or satisfied by such Party hereunder. No such notification will (or will be deemed to) modify or result in the waiver of any representation, warranty, obligation, acknowledgment, or condition hereunder.

Each Party shall promptly notify each other Party of any event or circumstance that such Party becomes aware of that is reasonably likely, individually or taken together with all other events and circumstances known to such Party, to result in a SFEG Material Adverse Change or a IGS Material Adverse Change.

After the Effective Time, IGS shall, and shall cause the Surviving Corporation to, subject to applicable Law, comply with SFEG’s obligations under SFEG’s certificate of incorporation and bylaws and the indemnification agreements between SFEG, on the one hand, and SFEG’s directors and officers as of or immediately prior to the Effective Time, on the other hand (such directors and officers, collectively, the “Covered Parties”), in each case as in effect immediately prior to the Effective Time and disclosed in Section 6.7 of SFEG Disclosure Letter.

Prior to the Closing, SFEG shall purchase, and after the Effective Time the Surviving Corporation shall maintain, directors’ and officers’ liability insurance covering, for a period commencing at the Effective Time and ending on the sixth anniversary of the Effective Time, the directors and officers of each SFEG Entity who are currently covered by SFEG’s existing directors’ and officers’ liability insurance with respect to claims arising from facts or events that occurred before the Effective Time, on terms and conditions no less favorable to such directors and officers than those in effect on the Signing Date; except that the aggregate of all premiums for such insurance is not required to exceed $50,000, in the aggregate, for such insurance on the Signing Date.

Except as required by applicable Law, prior to the Effective Time, IGS and SFEG shall consult with each other before issuing any press release, making any other public statement, or scheduling any press conference or conference call with investors or analysts with respect to this Agreement or the Transactions. Prior to the Effective Time, each Party shall not issue any press release or other public statement concerning the Transactions without first providing the other Parties with a written copy of the text of such release or statement and obtaining the consent of the other Parties to such release or statement (which consent the other Parties shall not unreasonably withhold, delay, or condition).
