               (c) Without the Board’s prior approval, from the Closing until the fifth (5th) anniversary of the Closing, no Party may directly or indirectly (i) solicit or accept the employment of any current or former employees of the Company or its Subsidiary or (ii) hire, re-hire, agree to have as a contractor or otherwise employ such employees of the Company or its Subsidiary.

               (d) All intellectual property developed by employees of the Company after the Closing shall belong to the Company.

          Section 6.9 Confidentiality.

               (a) General Obligations. Each Party and the Company (the “Receiving Party”) undertakes to the other Parties and/or the Company (the “Disclosing Party”) that it shall, and shall procure that their respective Representatives shall, treat as confidential and not reveal to any third party Confidential Information, without the prior written consent of the Disclosing Party, or use any Confidential Information of any Disclosing Party in such manner other than for the benefit of, or for the provision of services to, such Disclosing Party.

               (b) Exceptions. The Parties and the Company acknowledge and agree that the confidentiality obligations set forth herein shall not extend to:

     (i) Confidential Information that (x) is publicly available or (y) becomes publicly available through no act or omission of the Receiving Party, or (z) becomes available on a non-confidential basis from a source (other than the Receiving Party) so long as such source is not known by such Receiving Party to be prohibited from disclosing such information to such Receiving Party by a legal, contractual or fiduciary obligation to the Disclosing Parties or any of their Representatives;

     (ii) Confidential Information that is required to be disclosed to any Governmental Entity or to the public in accordance with applicable Law; provided that in the event a Receiving Party (or its Affiliates or its or their respective Representatives) becomes legally compelled to disclose any information, knowledge or data that is subject to the confidentiality provisions of this Section 6.9, such compelled Receiving Party shall provide the Disclosing Parties with prompt written notice of such requirement so that the Disclosing Parties may seek, at their expense, a protective order, injunction or other remedy and, if such protective order, injunction or other remedy is not obtained, the compelled Receiving Party shall use its best efforts to disclose only that portion of the Confidential Information that is required by the applicable Law and to obtain assurances that confidential treatment will be afforded to such disclosed material; and

     (iii) Confidential Information that is disclosed to a Representative, so long as such Representative (i) is under a substantially similar obligation of confidentiality and (ii) such disclosure is on a need-to-know basis.

               (c) Other Information. The provisions of this Section 6.9 shall be in addition to, and not in substitution for, the provisions of any separate nondisclosure agreement executed by any Party or the Company with respect to the contemplated transactions under this Agreement.

               (d) Notices. All notices required under this Section 6.9 shall be made pursuant to Section 10.9 of this Agreement.

          Section 6.10 Expenses. Except as otherwise expressly provided herein, all costs and expenses incurred in connection with the preparation and execution of this Agreement shall be paid by the Party incurring such expense. Without limiting the generality of the foregoing, each Party shall pay all legal, accounting and investment banking fees and other fees to consultants and advisors incurred by it relating to this Agreement and the transactions contemplated herein.

          Section 6.11 Further Assurance. At any time and from time to time after the Closing Date, each Party hereby agrees and covenants that it shall (i) use its reasonable best efforts to ensure the due performance and observance by the Company of its obligations under this Agreement; (ii) assist the Company in obtaining Governmental Authorizations and all other relevant approvals, certificates or registrations in various jurisdictions and communicating with Governmental Entities as necessary to explore business opportunities, conduct business transactions or engage in other activities in such jurisdictions (at the sole expense of the Company); (iii) cause its representatives on the Board to implement the Board resolutions and act in the Company’s best interests in accordance with this Agreement; and (iv) do all such further acts and things, all as the other Parties may reasonably request for the purpose of carrying out the intent of this Agreement.

          Section 6.12 Indemnification.

               (a) Indemnification. Each Party and/or the Company (the “Indemnifying Party”), agrees to indemnify, defend and hold harmless the other Parties and/or the Company, such other Parties’ and/or the Company’s Affiliates and their respective directors, officers, shareholders, partners, agents and employees and their successors and assigns (each, an “Indemnified Party”), from, against and in respect of any damages, claims, losses, charges, actions, suits, penalties and reasonable costs and expenses (including reasonable attorney’s fees), to the extent determined by the final judgment or award of a court of competent jurisdiction or arbitration tribunal or in connection with a settlement entered into in accordance with the terms and conditions of this Agreement (collectively, the “Losses”), imposed on, sustained, incurred or suffered by or asserted against any of the Indemnified Parties, relating to or arising out of:

     (i) any breach or inaccuracy of any representation or warranty made by the Indemnifying Party in this Agreement, other than those, if any, that have been waived in writing by the other Parties and/or the Company; or

     (ii) the breach of any covenant or agreement of the Indemnifying Party contained in this Agreement, other than those, if any, that have been waived in writing by the other Parties and/or the Company.

The Indemnifying Party shall not be liable to the Indemnified Parties for any Losses arising out of or resulting from any corrective or remedial action taken or permitted to be taken by the Indemnified Parties unless the Indemnifying Party shall have consented to such corrective or remedial action (such consent not to be unreasonably withheld). In determining whether a proposed corrective or remedial action is reasonable, the Parties and/or the Company shall take into account, among other relevant factors, (A) the requirements of Law, (B) what is reasonably advisable in order to avoid a material potential liability, (C) the industry standards and practices in respect of similar facts and circumstances and (D) the monetary costs and benefits of such action (as opposed to no action or alternative possible actions) to the Indemnified

Parties (without regard to the existence of any indemnification obligation of the Indemnifying Party under this Section 6.12).

For the avoidance of doubt, the obligation of an Indemnifying Party to indemnify an Indemnified Party hereunder shall not be duplicative of any obligation of such Indemnifying Party to indemnify such Indemnified Party under another Transaction Document.

               (b) Third-Party Claim Indemnification Procedures.

     (i) In the event that any written claim or demand for which the Indemnifying Party may have liability to any Indemnified Party hereunder is asserted against or sought to be collected from any Indemnified Party by a third party (a “Third-Party Claim”), such Indemnified Party shall promptly, but in no event more than ten (10) calendar days following such Indemnified Party’s receipt of a Third-Party Claim, notify the Indemnifying Party in writing of such Third-Party Claim, the amount or the estimated amount of damages sought thereunder to the extent then ascertainable (which estimate shall not be conclusive of the final amount of such Third-Party Claim), any other remedy sought thereunder, any relevant time constraints relating thereto and, to the extent practicable, any other material details pertaining thereto (a “Claim Notice”). The Indemnifying Party shall have thirty (30) calendar days (or such lesser number of days set forth in the Claim Notice as may be required by court proceeding in the event of a litigated matter) after receipt of the Claim Notice (the “Notice Period”) to notify the Indemnified Party that it desires to defend the Indemnified Party against such Third-Party Claim.

     (ii) In the event that the Indemnifying Party notifies the Indemnified Party within the Notice Period that it desires to defend the Indemnified Party against a Third-Party Claim, the Indemnifying Party shall have the right to defend the Indemnified Party by appropriate proceedings and shall have the sole power to direct and control such defense at its expense. Once the Indemnifying Party has duly assumed the defense of a Third-Party Claim, the Indemnified Party shall have the right, but not the obligation, to participate in any such defense and to employ separate counsel of its choosing. The Indemnified Party shall participate in any such defense at its own expense unless the Indemnifying Party and the Indemnified Party are both named parties to the proceedings and the Indemnified Party shall have reasonably concluded that representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. The Indemnifying Party shall not, without the prior written consent of the Indemnified Party, settle, compromise or offer to settle or compromise any Third-Party Claim on a basis that would result in (i) the imposition of a consent order, injunction or decree that would restrict the future activity or conduct of the Indemnified Party or any of its Affiliates, (ii) a finding or admission of a violation of Law or violation of the rights of any Person by the Indemnified Party or any of its Affiliates, or (iii) any monetary liability of the Indemnified Party that will not be paid or reimbursed by the Indemnifying Party.

     (iii) If the Indemnifying Party elects not to defend the Indemnified Party against a Third-Party Claim, whether by not giving the Indemnified Party timely notice of its desire to so defend or otherwise, the Indemnified Party shall have the right but not the obligation to assume its own defense; it being understood that the Indemnified Party’s right to indemnification for a Third-Party Claim shall not be adversely affected by assuming the defense of such Third-Party Claim. The Indemnified Party shall not settle a Third-Party Claim without the consent of the Indemnifying Party, which consent shall not be unreasonably withheld.

     (iv) The Indemnified Party and the Indemnifying Party shall cooperate in order to ensure the proper and adequate defense of a Third-Party Claim, including by providing access to each other’s relevant business records and other documents and employees; it being

understood that the costs and expenses of the Indemnified Party relating thereto shall be Losses for purposes of Section 6.12(a).

     (v) The Indemnified Party and the Indemnifying Party shall use reasonable best efforts to avoid production of Confidential Information (consistent with applicable Law), and to cause all communications among employees, counsel and others representing any party to a Third-Party Claim to be made so as to preserve any applicable attorney-client or work-product privileges.

               (c) No Consequential Damages. Notwithstanding anything to the contrary contained in this Agreement or provided for under any applicable Law, in no event shall the parties hereto have any liability as against any Indemnified Party for any indirect, incidental, consequential, special, exemplary or punitive damages whether based on breach of contract, tort (including negligence) or otherwise, or any loss of future revenue, income or profits or any diminution of value relating to the breach or alleged breach hereof, whether or not the possibility of such damages has been disclosed to the other parties in advance or could have been reasonably foreseen by such other parties; and any such damages in the foregoing shall not be included in the Losses hereunder.

               (d) Adjustments to Losses.

     (i) Insurance. In calculating the amount of any Losses, the proceeds actually received by the Indemnified Party or any of its Affiliates under any insurance policy or pursuant to any claim, recovery, settlement or payment by or against any other Person, net of any actual costs, expenses or premiums incurred in connection with securing or obtaining such proceeds, shall be deducted therefrom. In the event that an Indemnified Party has any rights against a third party with respect to any occurrence, claim or loss that results in a payment by an Indemnifying Party under this Section 6.12, such Indemnifying Party shall be subrogated to such rights to the extent of such payment; provided that until the Indemnified Party recovers full payment of the Losses related to any such claim, any and all claims of the Indemnifying Party against any such third party on account of said indemnity payment are hereby expressly made subordinate and subject in right of payment to the Indemnified Party’s rights against such third party. Without limiting the generality or effect of any other provision hereof, each Indemnified Party and Indemnifying Party shall duly execute upon request all instruments reasonably necessary to evidence and perfect the subrogation and subordination rights detailed herein, and otherwise cooperate in the prosecution of such claims.

     (ii) Taxes. In calculating the amount of any Losses, there shall be deducted an amount equal to any net Tax benefit actually realized (including the utilization of a Tax loss or Tax credit carried forward but ignoring the effect of any shortfall in payment or provision for Tax payable) as a result of such Losses by the party claiming such Losses.

     (iii) Reimbursement. If an Indemnified Party recovers an amount from a third party in respect of any Losses that is the subject of indemnification hereunder after all or a portion of such Losses has been paid by an Indemnifying Party pursuant to this Section 6.12, the Indemnified Party shall promptly remit to the Indemnifying Party the excess (if any) of (i) the amount paid by the Indemnifying Party in respect of such Losses, plus the amount received from the third party in respect thereof, less (ii) the full amount of Losses. For the avoidance of doubt, no Indemnified Party shall be entitled to recover damages or obtain payment, reimbursement, restitution or indemnity more than once in respect of any one fact, matter, event or circumstance that gives rise to more than one claim.

               (e) Payments. The Indemnifying Party shall pay all amounts payable pursuant to this Section 6.12, by wire transfer of immediately available funds, promptly following receipt from an Indemnified Party of a bill, together with all accompanying reasonably detailed back-up documentation, for any Losses that are the subject

of indemnification hereunder, unless the Indemnifying Party in good faith disputes such Losses, in which event it shall so notify the Indemnified Party. In any event, the Indemnifying Party shall pay to the Indemnified Party, by wire transfer of immediately available funds, the amount of any Losses for which it is liable hereunder no later than ten (10) days following any final determination of such Losses and the Indemnifying Party’s liability therefor or a settlement entered into in accordance with the terms and conditions of this Agreement. A “final determination” shall exist when (i) the parties to the dispute have reached an agreement in writing, or (ii) an arbitration panel shall have rendered a final non-appealable determination with respect to disputes the parties have agreed to submit thereto pursuant to Section 10.10.

               (f) Mitigation. Each Indemnified Party shall use its commercially reasonable efforts to mitigate any indemnifiable Losses. In the event an Indemnified Party fails to so mitigate any indemnifiable Losses, the Indemnifying Party shall have no liability for any portion of such Losses that reasonably could have been avoided had the Indemnified Party made such efforts. Without limiting the foregoing, after any Indemnified Party acquires knowledge of any fact or circumstance that results in or would be reasonably expected to result in any indemnifiable Losses or Third-Party Claim hereunder, the Indemnified Party shall notify the Indemnifying Party promptly and implement, and cause each other Indemnified Party to implement, such commercially reasonable actions as the Indemnified Party shall request in writing for the purposes of mitigating the possible Losses arising therefrom (such actions, “Mitigation Actions”). In determining whether a proposed Mitigation Action is reasonable, the parties will take into account, among other relevant factors, (i) the requirements of Law, (ii) what is reasonably advisable in order to avoid a material potential liability, (iii) the industry standards and practices in respect of similar facts and circumstances and (iv) the monetary costs and benefits of such action (as opposed to no action or alternative possible actions), without regard to the existence of any indemnification obligation of the parties under this Section 6.12.

Article VII

compliance with laws

          Section 7.1 Compliance with Applicable Law. The Company shall at all times be in compliance in all material respects with applicable Law, including applicable PRC Law. For the avoidance of doubt, the Company shall at all times comply with the applicable requirements of the FCPA and as well as applicable non-U.S. law implementing the OECD Convention on Combating Bribery of Foreign Public Officials in International Business or other non-U.S. anti-bribery conventions and anti-corruption and anti-bribery laws (collectively, the “Anti-bribery Laws”); the OFAC Regulations; all U.S. statutory and regulatory requirements and export and import control Laws and regulations related to the export or transfer of commodities, software and technology, including the Arms Export Control Act, as amended or any successor statute of similar import (22 U.S.C. § 2778), ITAR, the Export Administration Regulations, as amended or any successor regulations of similar import (15 C.F.R. § 730 et seq.) and associated executive orders (collectively the “Export Control Laws”); and anti-boycott laws, regulations and guidelines of the U.S., including Section 999 of the Internal Revenue Code and the regulations and guidelines issued pursuant thereto and the Export Administration Regulations administered by the U.S. Department of Commerce, as relating to anti-boycott matters (the “Anti-boycott Laws”).

          Section 7.2 Compliance Policies. Without limiting the foregoing, the Parties shall cause the JV Group to maintain and enforce an Export Controls and Sanctions Compliance Plan (“ECSCP”). The Company’s ECSCP as of the date hereof is set forth in Annex B, which the Company may amend from time to time. The ECSCP will include compliance policies and procedures designed to prevent, and not to engage in, any business relationships or transactions between the JV Group and (i) any Sanctioned Country, (ii) any Sanctions Target, or any entity or individual directly or indirectly owned or controlled by any Sanctions Target or (iii) any of the Parties or their Affiliates that would further activities of those Parties or Affiliates in a Sanctioned Country or with a Sanctions Target.

Anti-bribery Laws and (ii) all Export Control Laws, especially with respect to the assets contributed to the JV Group by ION or BGP and any products, services or technologies that make use of such contributed assets. The Parties shall cause the Company to appoint an “Export Control Administrator,” who will be a U.S. citizen or U.S. permanent resident, to be responsible for the implementation of and monitoring compliance with the ECSCP.

          Section 7.3 Compliance Advisor. The Parties also agree that they shall cause the Board, consistent with their duties as directors, to appoint, as an advisor to the Board, an individual with extensive experience in compliance with U.S. economic sanctions, export and re-export control laws, the FCPA and Anti-boycott Laws. This advisor will assist the Board in overseeing the Company’s compliance with such Laws.

Article VIII

Transfer Restrictions

          Section 8.1 Transfer Restriction.

          Except as provided in Section 8.2, no Party may, at any time, directly or indirectly, by Change of Control or operation of Law, Transfer any of its Equity Interest (unless expressly superseded by express terms hereof) to any Person without the prior written consent of the other Parties and the approval of the Examination and Approval Authority and such Transfers shall be deemed void.

          Section 8.2 Permitted Transfers.

          Notwithstanding the provisions of Section 8.1 hereof, the following Transfers shall be permitted (it being agreed by the Parties that the prior written consent of the other Parties shall be deemed to have been obtained to effect the following Transfers), subject to the approval of the same by the Examination and Approval Authority and/or other applicable Government Entity:

               (a) BGP may Transfer all or any part of its Equity Interest in the Company as required under applicable Law, regulation or government policy where such Law, regulation or government policy mandates that BGP shall no longer be the holder of such Equity Interest, provided that such Permitted Transferee agrees to be bound by all terms applicable to the ownership of the Company including becoming a Party to this Agreement and all other applicable agreements, subject to applicable Law;

               (b) Each Party may Transfer its Equity Interest pursuant to a Change of Control provided (i) that it complies with the procedures for a Right of First Refusal to the other Parties as set forth in Section 8.4 as to its Equity Interest and (ii) that the Permitted Transferee is not a competitor of the Company or of the other Parties;

               (c) On or after the fifth (5th) anniversary of the Closing, following compliance with the procedures for a Right of First Refusal to the other Parties as set forth in Section 8.4, each Party may Transfer its Equity Interest to a Permitted Transferee other than a competitor of the Company or of the other Parties; provided that such Permitted Transferee agrees to abide by all terms applicable to the ownership of the Company including becoming a Party to this Agreement and all other applicable agreements; and

               (d) ION is permitted to pledge its Equity Interest to China Merchants Bank Co., Ltd., New York Branch (“CMB”), agent, as security for the repayment of obligations under the Credit Agreement dated as of March ___, 2010, among ION, ION International S.à.r.l., the guarantors party thereto, the lenders party thereto and CMB, or to any successor agent pursuant to any refinancing of such credit agreement.

          Section 8.3 Condition to the Permitted Transfer. Any Permitted Transferee shall have executed and delivered to the other Parties an instrument in form and substance reasonably satisfactory to the other Parties confirming that such Permitted Transferee agrees to become a Party to this Agreement and to assume and be liable for the obligations of the transferring Party and accept such a Transfer subject to all of the terms and conditions hereof and thereof.

          Section 8.4 Right of First Refusal.

               (a) In the event that an Offering Party makes a Transfer Election pursuant to Section 8.2(b) or Section 8.2(c) (it is agreed and acknowledged by the Parties that the Equity Interest transferred in any Transfer Election shall not be less than the total Equity Interest held by such Party as of the date of the Offer Notice), the Offering Party shall make an Offer to the Receiving Party or Receiving Parties to acquire the Offered Interest at the Offer Price (the “Right of First Refusal”). An Offer Notice shall be delivered to each Receiving Party.

               The Offer Notice shall specify (i) the Offered Interest, (ii) the Offer Price, (iii) the identity of the Proposed Transferee, and (iv) all other material terms and conditions of the Proposed Transfer. The Offer Notice shall constitute an irrevocable offer to sell all of the Offered Interest at a purchase price equal to the Offer Price, and on the same terms and conditions as set forth in the Offer Notice.

               In the event that any Receiving Party notifies the Offering Party within the ROFR Option Period that such Receiving Party wishes to accept the Offer, the Offering Party and such Receiving Party and any other Receiving Parties wishing to accept the Offer shall, for a period of one (1) month (the “Drafting Period”), negotiate in good faith and use all reasonable efforts to enter into a Receiving Party Agreement, provided, that the Receiving Party Agreement shall provide that such purchase shall be made for the Offer Price and in the event more than one Receiving Parties enter into the Receiving Party Agreement, such Receiving Parties shall purchase the Offered Interest pro rata based on their respective Percentage Interest unless otherwise agreed to among the Receiving Parties. The failure of a Receiving Party to respond within the ROFR Option Period shall be deemed to be a waiver of its rights under this Section 8.4 with respect to such Proposed Transfer only.

               (b) In the event that the Offering Party and any Receiving Party enter into the Receiving Party Agreement:

     (i) the Offering Party and the Receiving Party or Parties shall agree on a Target ROFR Completion Date, for the ROFR Completion, provided, that the interval between the date on which the Offering Party and such Receiving Party or Parties enter into the Receiving Party Agreement and the Target ROFR Completion Date be sufficient to allow the Offering Party and such Receiving Party or Parties to, and the Offering Party and such Receiving Party or Parties shall agree to, use all reasonable efforts to (x) satisfy the ROFR Completion Regulatory Requirements; and (y) fulfill as promptly as practicable the other conditions that might be applicable to the ROFR Completion and take such other actions (including promptly preparing and filing all necessary documentation and executing any necessary agreements, instruments and documents) required to consummate the ROFR Completion. Notwithstanding the foregoing, the Parties agree that no Receiving Party shall be required to sell or hold separate, or agree to sell or hold separate, any assets, businesses or interest in any assets or businesses or to agree to any changes or restrictions in either the operations of any such assets or businesses or the rights of such Receiving Party;

     (ii) in the event that any Receiving Party has not, after use of all reasonable efforts, satisfied all of the ROFR Completion Regulatory Requirements by the Target ROFR Completion Date, the Target ROFR Completion Date shall be extended by two (2) months to allow such Receiving Party additional time to satisfy the ROFR Completion Regulatory

Requirements (unless such requirements are incapable of being satisfied on reasonably satisfactory terms pursuant to clause (iv) below);

     (iii) on the ROFR Completion Date, the Receiving Party or Parties shall transmit the Offer Price, by wire transfer of immediately available funds, to the account as reasonably designated by the Offering Party; and

     (iv) if one or more ROFR Completion Regulatory Requirements are reasonably incapable of being satisfied on reasonably satisfactory terms despite compliance by the Receiving Party or Parties with the terms of clause (i) of this Section 8.4(b), the Receiving Party or Parties shall inform the Offering Party of the details and shall not be required to effect the ROFR Completion, and the Offering Party shall retain its Equity Interest on the same terms as such Equity Interest were held at the time it made such Offer. For the avoidance of doubt, if the ROFR Completion is not effected pursuant to this clause (iv) of Section 8.4(b), the Receiving Party or Parties shall not be required to make any payment to the Offering Party.

               (c) In the event that (w) all Receiving Parties notify the Offering Party that such Receiving Party or Parties do not wish to accept the Offer or (x) all Receiving Parties fail to notify the Offering Party prior to the expiration of the Offer Period that the Receiving Party or Parties wish to accept the Offer or (y) the Offering Party and the Receiving Party or Parties fail to enter into a Receiving Party Agreement due to any Receiving Party’s breach of this Agreement or (z) the Offering Party and the Receiving Party or Parties fail to consummate the ROFR Completion due to any Receiving Party’s breach of this Agreement or the Receiving Party Agreement (each of the foregoing, a “Decision Not To Proceed”), the Offering Party may enter into a Third-Party Acquisition Agreement to Transfer the Offered Interest to a Third-Party Buyer, provided, that:

     (i) the Third-Party Acquisition Agreement shall be executed and consummated by no later than six (6) months after date of the Decision Not To Proceed; and

     (ii) the Third-Party Acquisition Agreement shall provide that the Third-Party Buyer will purchase the Offered Interest for an up-front amount in cash equal to no less than the Offer Price, and on terms and conditions not less favorable to the Offering Party than those set forth in the Offer Notice.

          Section 8.5 Deadlock Resolution and Put Right of ION.

               (a) In the event of any dispute between the Parties related to the Company (including a disagreement related to the operation or governance of the Company as contemplated hereunder or a breach by a Party or the Company of its obligations) or the consistent and repeated failure (on at least two separate occasions) by the Board or Parties to resolve any matter (or obtaining quorum on such matter), in addition to any other remedies required by applicable Law:

     (i) The chief executive officers of BGP and ION shall discuss the dispute in good faith on a regular basis for a period of thirty (30) days (or a lesser period if both Parties agree that a resolution is not forthcoming) following the occurrence of the dispute, in an effort to resolve the dispute;

     (ii) If no agreement is reached by the end of the discussion period described above, then the dispute will be referred to non-binding mediation for a period of not greater than sixty (60) days after the conclusion of the discussion period described above (provided that if the nature of the dispute is not conducive to resolution by mediation, the Parties may mutually agree to forego the mediation process); and

     (iii) If no resolution is reached at the conclusion of the mediation process described above, then each Party may refer the dispute to arbitration as provided in Section 10.10.

               (b) Notwithstanding anything contrary in this Agreement, at any time after the fifth (5th) anniversary of the Closing and prior to the eighth (8th) anniversary of the Closing, following the occurrence of (i) any failure to resolve as to any Fundamental Matter or Reserved Matter, (ii) a dispute over a material breach of the terms of this Agreement or (iii) a fundamental disagreement by the ION Directors or ION with respect to any significant management or operational matter concerning the Company that has been raised and discussed at least once at a meeting of the Board and has not been resolved; provided that, in each case, such dispute has undergone the procedures set forth in Section 8.5(a) above but prior to arbitration (a “Deadlock”), ION shall have the right to elect to require BGP to purchase all of its Equity Interest for the then fair market value of such Equity Interest as of the date of the Deadlock Notice (such a sale, the “Deadlock Sale”). The Deadlock Sale right and fair market value of such Equity Interest shall be as follows:

               (c) If ION elects to exercise its Deadlock Sale right as described above, it shall deliver a Deadlock Notice to BGP and the Company within twenty (20) Business Days following the occurrence of a Deadlock.

               (d) For a period of ten (10) Business Days following delivery of the Deadlock Notice, ION and BGP shall attempt in good faith to reach agreement on the fair market value of ION’s Equity Interest. If the Parties fail to agree on such value within the designated time period, ION and BGP shall, within ten (10) Business Days afterwards, agree upon two internationally recognized investment banking firms with expertise in valuing companies engaged in businesses similar or related to the Business. The Parties shall jointly be responsible for the fees and expenses of the selected investment banks.

               (e) Within twenty (20) Business Days of the selection of the investment banks pursuant to Section 8.5(d) above, each such investment bank shall independently determine, by using commonly accepted valuation techniques, the enterprise value of the entire Company on a 100% (one hundred percent) basis. The Company shall provide the investment banks with prompt access to such information of the Company as the investment banks may reasonably request to enable them to prepare their appraisal. On the thirtieth (30th) Business Day (or earlier or later if reasonably requested by such investment banks) following the selection of the two investment banks, each investment bank shall deliver its valuation report of the Company to the Parties and the enterprise value of the Company shall be equal to the average (mean) of the valuations determined by the two investment banks. The Parties shall then derive the fair market value of ION’s Equity Interest by subtracting the Company’s net debt from the Company’s enterprise value and multiplying the resulting value by ION’s Percentage Interest.

               (f) The Parties shall use their best efforts to obtain all Governmental Authorizations and other approvals and make all notifications necessary to complete the Deadlock Sale. In the event BGP fails to obtain necessary PRC approvals to complete the Deadlock Sale, it shall use its best efforts to designate a third party to purchase all of ION’s Equity Interest and such third party shall agree to be bound by and assume BGP’s obligations hereunder with respect to such Deadlock Sale. The Deadlock Sale shall be completed within twenty (20) Business Days after determination of the fair market value for ION’s Equity Interest as described above (whether by investment banks or by agreement of the Parties) or, if all necessary approvals are not obtained or if BGP has insufficient funds to acquire such Equity Interest in the Company in a Deadlock Sale by such date, within ten (10) Business Days after the receipt of all such approvals or expiration of an additional ninety (90) day grace period during which BGP may raise additional funding. Upon completion of the Deadlock Sale, all of ION’s Equity Interest shall be transferred to BGP, free and clear of all

encumbrances, and BGP shall pay the purchase price to ION in US$ by wire transfer of immediately available funds.

               (g) During the process of the Deadlock Sale, the Parties and the Company shall use their best efforts to continue to operate the Company in the Ordinary Course of Business of the Company.

          Section 8.6 Sale upon Material Breach.

          Upon a material breach by any Party of the terms of this Agreement that materially impedes in the conduct of the Business by the Company which is not cured within a period of two (2) months following written notice of such breach to such Party (a “Triggering Event”), the other Parties shall at their sole discretion have the right to buy all of the Equity Interest in the Company held by the Party undergoing the Triggering Event and those held by Affiliates of such Party for 80% (eighty percent) of the then fair market value of such Equity Interest determined in accordance with applicable procedures for a Deadlock Sale, as set forth in Section 8.5. In the event that more than one of the other Parties exercise their right according to this Section 8.6, such other Parties shall purchase the Equity Interest held by the Party undergoing the Triggering Event and those held by Affiliates of such Party pro rata based on such other Parties’ respective Percentage Interest unless otherwise agreed to among such other Parties.

Article IX

Term; termination, Dissolution and liquidation

          Section 9.1 Term and Extension.
