As promptly as practicable after the date of this Agreement, each Member of the Company Group shall make all filings required by Law to be made by it in order to consummate the Transactions, and shall cooperate with the Purchasers with respect to all filings that any Purchaser elects to make or shall be required by Law to make in connection with the Transactions and in obtaining all Required Consents.

Between the date of this Agreement and the Closing Date, the Company shall promptly notify the Purchasers in writing if the Company becomes aware of (a) any fact or condition that makes any Member of the Company Group’s representations and warranties untrue as of the date of this Agreement, (b) the occurrence after the date of this Agreement of any fact or condition that would make any Member of the Company Group’s representations and warranties untrue had such representation or warranty been made as of the date of the occurrence of such fact or condition, (c) any breach of any Member of the Company Group’s covenants in this Agreement, or (d) any fact or condition that could reasonably be expected to make the satisfaction of the conditions in Article 8 unlikely or impossible. Should any such fact or condition require any change to the Disclosure Schedule, the Company shall promptly deliver to the Purchasers a supplement to the Disclosure Schedule specifying such change; provided, that such delivery shall not affect any rights of the Purchasers hereunder.

Each Member of the Company Group shall use its reasonable best efforts to cause the conditions in Article 8 to be satisfied.

Without limiting the rights of the Purchasers under Section 6.9 of the Securities Purchase Agreement, for so long as Blue Ridge China or EI holds at least 25% of the number of Common Shares purchased by it under this Agreement:

(a) the Company shall, and shall cause the WFOE and the Operating Companies and any other Subsidiaries to, promptly and timely make any tax elections pursuant to the Code or any other applicable Law as may be required by the Purchasers in their sole discretion;

(b) prior to a Qualified Public Offering, the Company shall not, without the written consent of the Purchaser, issue or transfer shares (or rights to acquire shares) in the Company, and shall use its reasonable best efforts (and the Management Shareholders shall use their reasonable best efforts) to not permit issuances or transfers of shares or ownership interests (or rights to acquire ownership interests) in any Person who directly or indirectly owns shares in the Company, to any Person if following such issuance or transfer the Company, in the determination of counsel or accountants for the Purchaser, would be a “Controlled Foreign Corporation” (a “CFC”) as defined in the Code with respect to the shares held by any Purchaser. No later than two (2) months following the end of each Company taxable year, the Company shall provide the following information to the Purchasers: (i) the Company’s capitalization table as of the end of the last day of such taxable year and (ii) a report regarding the Company’s status as a CFC. In addition, the Company shall provide the Purchasers with access to such other Company information as may be reasonably required by such Purchasers to determine the Company’s status as a CFC, to determine whether each such Purchaser is required to report its pro rata portion of the Company’s “Subpart F income” (as defined in the Code) on its United States federal income tax return, or to allow such Purchasers to otherwise comply with applicable United States federal income tax laws. In the event that the Company is determined by counsel or accountants for the Purchasers to be a CFC as defined in the Code (or any successor thereto) with respect to the shares held by any Purchaser, the Company agrees to use commercially reasonable efforts to avoid generating for any taxable year in which the Company is a CFC, “subpart F income,” as such term is defined in Section 952 of the Code;

(c) the Company shall use its reasonable best efforts to avoid being a “passive foreign investment company” (“PFIC”) within the meaning of Section 1297 of the Code (or any successor thereto). In furtherance of the foregoing, the Company shall (no less frequently than as of the end of each calendar year and at such other times as it determines in good faith to be appropriate), in consultation with its professional advisors, take such reasonable steps as necessary to determine whether the Company could reasonably be expected to be classified as a PFIC or whether there is a material risk that it could be classified as a PFIC. The Company will promptly inform the Purchasers at any time that it determines that it could reasonably be expected to be so classified or there is a material risk thereof, and it will cooperate with the Purchasers in taking such actions as required by the first sentence of this paragraph (c) to avoid

being a PFIC. In connection with a “Qualified Electing Fund” election made by any Purchaser pursuant to Section 1295 of the Code (or any successor thereto), the Company shall provide annual financial information to the Purchasers in a PFIC Annual Information Statement in such reasonable form as provided by the Purchasers and shall provide the Purchasers with access to such other Company information as may be required for purposes of filing United States federal income tax returns in connection with such Qualified Electing Fund election;

(d) The representations, warranties and covenants in the forgoing paragraphs (b) and (c) shall be applicable with respect to each Subsidiary of the Company that would be classified as a corporation for U.S. Federal income tax purposes, and the Company shall cause such Subsidiary to comply with the foregoing as if such Subsidiary (and not just the Company) were named in such paragraphs. The Company shall also obtain representations, warranties and covenants from each entity in which it invests or has invested substantially to the effect of the representations, warranties and covenants contained in the foregoing paragraphs and such additional representations, warranties and covenants as shall be necessary to allow the Company to comply with the provisions of the foregoing provisions of this Section 6.5; and

(e) except to the extent that the Purchasers elect otherwise, and only if requested by the Purchasers, the Company shall take such reasonable actions, including making an election to be treated as a corporation or refraining from making an election to be treated as a partnership, as may be required to ensure that at all times the Company is treated as a corporation for United States federal income tax purposes;

provided that, all third-party reasonable fees and expenses in excess of $20,000 per year associated with the Company complying with this Section 6.5 and with Section 6.9 of the Securities Purchase Agreement shall be borne by the Purchasers.

Following the Closing Date and during the WFOE’s operational term, with such term to be approved by the Purchasers, the Company and Management Shareholder shall cause the WFOE’s capital to be freely and timely converted from foreign exchange into RMB according to the business needs approved by the Purchasers and all of the WFOE’s profits to be freely and timely repatriated to the Company.

As soon as reasonably practicable following the Closing Date, the Company will cause the real property acquired by the WFOE in HeFei and Suzhou to be transferred to newly formed wholly owned Subsidiaries of the WFOE in compliance with applicable Law.

On or prior to December 31, 2006, the Company shall deliver to the Purchasers the revised 2007 Budget, which shall be in form and substance reasonably satisfactory to the Purchasers.

As promptly as practicable after the date of this Agreement, each Purchaser shall make all filings required by Law to be made by it to consummate the Transactions. Each Purchaser shall cooperate with the Company with respect to all filings the Company shall be required by Law to make and in obtaining all Required Consents; provided, that no Purchaser shall be required to dispose of any of its assets or properties, or make any change to its business, or expend any material funds in order to comply with this Section 7.1.

Between the date of this Agreement and the Closing Date, each Purchaser shall promptly notify the Company in writing if such Purchaser becomes aware of (a) any fact or condition that makes any of its representations and warranties untrue as of the date of this Agreement, (b) the occurrence after the date of this Agreement of any fact or condition that would make any of its representations and warranties untrue had such representation or warranty been made as of the date of the occurrence of such fact or condition, (c) any breach of any of its covenants in this Agreement, or (d) any fact or condition that could reasonably be expected to make the satisfaction of the conditions in Article 9 unlikely or impossible.

The obligations of the Purchasers to consummate the Transactions to be effected at the Closing are subject to the fulfillment or waiver on or before the Closing Date of each of the conditions set forth in this Article 8.

All representations and warranties of each Member of the Company Group in this Agreement shall have been accurate in all material respects as of the date of this Agreement, and shall be accurate in all material respects as of the time of the Closing Date as if made on and as of such date, without giving effect to any supplement to the Disclosure Schedule; provided, that each of the representations and warranties in this Agreement that contains an express materiality qualification shall have been accurate in all respects as of the date of this Agreement, and shall be accurate in all respects as of the time of the Closing Date as if made on and as of such date, without giving effect to any supplement to the Disclosure Schedule.

All of the covenants and obligations that any Member of the Company Group is required to perform or to comply with pursuant to this Agreement at or prior to the Closing shall have been duly performed and complied with in all material respects.

Each of the Required Consents, including with respect to the Operating Companies, shall have been obtained in a form and substance reasonably acceptable to the Purchasers and shall be in full force and effect, and the Company shall have delivered copies thereof to the Purchasers. None of such Required Consents shall be subject to conditions that are unacceptable to the Purchasers in their reasonable judgment.

There shall not be existing or threatened against any Purchaser or any Member of the Company Group by any Governmental Body any action, claim, suit or other proceeding involving any challenge to, or seeking damages or other relief in connection with, any of the Transactions, or that may have the effect of preventing, delaying, making illegal, imposing limitations or conditions on or otherwise interfering with the Transactions.

After the date hereof, no Law or interpretation thereof shall have been enacted or made, nor shall any Order have been issued, by or on behalf of any Governmental Body, which, in the Purchasers’ reasonable judgment, would materially and adversely affect foreign investments in the PRC (including any Law, interpretation or Order limiting the ownership or control of domestic business ventures by foreign Persons, or the ability of foreign Persons to repatriate funds held by domestic business ventures) or would otherwise materially and adversely affect the Purchased Securities or the benefits expected to be derived by the Purchasers from the purchase of the Purchased Securities or by the Company from the sale of the Purchased Securities.

As of the Closing Date, each of the following documents shall have been duly executed and delivered by the parties thereto (other than the Purchasers), each in substance and form satisfactory to the Purchasers, and each such document shall be in full force and effect and filed, as required or appropriate, with applicable Governmental Authorities, and no term or condition thereof shall have been supplemented, amended, modified or waived without the Purchasers’ prior written consent, and any transactions contemplated thereby shall have been consummated (or will be consummated concurrently with the Closing) in accordance with the terms and conditions thereof:

The Company shall have delivered to each of the Purchasers a certificate of the President (or comparable officer) of the Company, dated the Closing Date, certifying as to the satisfaction of the conditions set forth in Section 8.1 through Section 8.6 and Section 8.12.

Neither the consummation nor the performance of any of the Transactions will, directly or indirectly (with or without notice or lapse of time), contravene or conflict with or result in a violation of or cause any Purchaser to suffer any adverse consequence under any applicable Law or Order.

The Company shall have delivered to each of the Purchasers a certificate of the Secretary of the Company, dated the Closing Date, attaching (i) correct and complete copies of the Governing Documents then in effect, (ii) correct and complete copies of all resolutions of the Board of Directors of the Company relating to the Transactions, and (iii) a certificate of good standing of the Company issued by the applicable Governmental Body no earlier than five Business Days before the Closing Date.

(a) On the Closing Date, each Purchaser shall have received from King & Wood, counsel to the Company and the Management Shareholders, an opinion addressed to the Purchasers, dated as of the Closing Date, in form and substance reasonably acceptable to the Purchasers and similar to the legal opinion delivered to the Purchasers by King & Wood pursuant to the Securities Purchase Agreement.

(b) On the Closing Date, each Purchaser shall have received from Maples and Calder, counsel to the Company, an opinion addressed to the Purchasers, dated as of the Closing Date, reasonably acceptable to the Purchasers and similar to the legal opinion delivered to the Purchasers by Maples and Calder pursuant to the Securities Purchase Agreement.

As of the Closing Date, all corporate and other proceedings taken or to be taken in connection with the Transactions and all documents incidental thereto shall be reasonably satisfactory in form and substance to the Purchasers and their counsel, and the Purchasers and their counsel shall have received all such counterpart originals or certified or other copies of such documents as they may reasonably request. The Memorandum of Association shall have been duly and validly adopted conditional upon, and with effect immediately before, the Closing.

The Company shall have operated in compliance with the 2006 Budget prior to the Closing Date.

The acquisition by Henan Xinyuan of one hundred percent (100%) of the issued and outstanding capital stock of each of the Ancillary Businesses from the Management Shareholders shall have been duly completed pursuant to the terms of the acquisition agreements referred to in Section 4.14(b), without any waiver or modification of any of the terms thereof.

The obligations of the Company and the Management Shareholders to consummate the Transactions to be effected at the Closing are subject to the fulfillment or waiver on or before the Closing Date of each of the conditions set forth in this Article 9.

All of the Purchasers’ representations and warranties in this Agreement shall have been accurate in all material respects as of the date of this Agreement, and shall be accurate in all material respects as of the time of the Closing as if made on and as of such date; provided, that each of the representations and warranties in this Agreement that contains an express materiality qualification shall have been accurate in all respects as of the date of this Agreement, and shall be accurate in all respects as of the Closing Date as if made on and as of such date.

All of the covenants and obligations that the Purchasers are required to perform or to comply with pursuant to this Agreement at or prior to the Closing shall have been duly performed and complied with in all material respects.

Since the date of this Agreement, there shall not have been commenced or threatened against any Member of the Company Group by any Governmental Body any action, claim, suit or other proceeding involving any challenge to, or seeking damages or other relief in connection with, any of the Transactions, or that may have the effect of preventing, delaying, making illegal, imposing limitations or conditions on or otherwise interfering with the Transactions.

Neither the consummation nor the performance of any of the Transactions will, directly or indirectly (with or without notice or lapse of time), contravene or conflict with or result in a violation of or cause the Company to suffer any adverse consequence under any applicable Law or Order.

As of the Closing Date, all corporate and other proceedings taken or to be taken in connection with the Transactions and all documents incidental thereto shall be reasonably satisfactory in form and substance to the Company and its counsel, and the Company and its counsel shall have received all such counterpart originals or certified or other copies of such documents as they may reasonably request.

As of the Closing Date, each of the Related Documents to which a Purchaser is a party shall have been duly executed and delivered by such Purchaser and shall be in full force and effect.

If (a) any of the conditions set forth in this Article 9 with respect to a Purchaser are not satisfied or waived (such Purchaser, the “Non-Closing Purchaser”), (b) all of the conditions set forth in this Article 9 with respect to the other Purchaser are satisfied or waived (such Purchaser, the “Closing Purchaser”), and (c) all of the conditions set forth in Article 8 are satisfied or waived, then upon written notice by the Closing Purchaser to the Non-Closing Purchaser (with a copy to the Company), all of the Non-Closing Purchaser’s rights hereunder shall be deemed to have been assigned and all of the Non-Closing Purchaser’s obligations hereunder shall be deemed to have been delegated to the Closing Purchaser (including with respect to the purchase of the Purchased Securities and payment of the Purchase Price), and the Non-Closing Purchaser shall no longer be a Purchaser for purpose of this Agreement or a party to any Related Document.

In connection with the transactions contemplated by Section 8.13 of this Agreement, each of the Purchasers shall have delivered to the Company and Zhang Yong a letter in form satisfactory to the Company and Zhang Yong waiving the requirements of Section 6.12(b) of the

Securities Purchase Agreement and providing written consent pursuant to Section 6.12(a) of the Securities Purchase Agreement for the release of $1,250,000, or such equivalent in RMB, from escrow to Zhang Yong as partial consideration for the sale of the Ancillary Businesses by the Management Shareholders to Henan Xinyuan pursuant to the terms of the acquisition agreements referred to in Section 4.14(b).

(a) The Company agrees to indemnify, defend and hold harmless the Purchasers and their respective Affiliates, and the partners, members, shareholders, managers, directors, employees and agents of each of the foregoing, from and against and in respect of any and all demands, claims, actions or causes of action, assessments, losses, damages, liabilities, interest and penalties, diminution in value of securities, costs and expenses (including, without limitation, reasonable legal fees and disbursements incurred in connection therewith and in seeking indemnification therefor, and any amounts or expenses required to be paid or incurred in connection with any action, suit, proceeding, claim, appeal, demand, assessment or judgment) (collectively, “Losses”), resulting from, arising out of, or imposed upon or incurred by any Person to be indemnified hereunder by reason of (i) any breach of any representation, warranty, covenant or agreement of the Company or the Management Shareholders contained in this Agreement or any agreement, certificate or document executed and delivered by the Company or any other Member of the Company Group pursuant hereto or in connection with any of the Transactions or (ii) any matter set forth on Schedule II.

(b) Notwithstanding anything herein to the contrary, the Company shall not be obligated to indemnify the Purchasers under this Section 10.1 in excess of an aggregate amount of $15,000,000 (the “Company’s Indemnification Cap”); provided, however, that the Company’s Indemnification Cap shall not apply to any Company indemnification obligations arising out of, relating to or resulting from fraud or intentional misrepresentation by the Company or the Management Shareholders.

Whenever a claim shall arise for indemnification under this Article 10, with the exception of claims for litigation expenses to be funded on an ongoing basis, the Person entitled to indemnification (the “Indemnified Party”) shall promptly notify the party from whom indemnification is sought (the “Indemnifying Party”) of such claim and, when known, the facts constituting the basis for such claim. Failure of an Indemnified Party to give reasonably prompt notice of any claim shall not release, waive or otherwise affect an Indemnifying Party’s obligations with respect thereto except to the extent that the Indemnifying Party can demonstrate actual loss and prejudice as a result of such failure. In the event of any such claim for indemnification resulting from or in connection with a claim or legal proceeding by a third party, the Indemnifying Party may, at its sole cost and expense, elect by notice to the Indemnified Party to assume the defense; provided, however, that the Indemnifying Party makes such election within 15 days after delivery of notice of claim from the Indemnified Party and agrees in writing

to pay the full amount of such indemnification to the Indemnified Party. If an Indemnifying Party assumes the defense of any such claim or legal proceeding, the Indemnifying Party shall be entitled to select counsel satisfactory to the Indemnified Party and take all steps necessary in the settlement or defense thereof; provided, that no settlement shall be made without the prior written consent of the Indemnified Party unless the settlement involves only payment of money damages by the Indemnifying Party and a release of the Indemnified Party from all liability. The Indemnified Party may, at its own expense, participate in any such proceeding with the counsel of its choice. So long as the Indemnifying Party is in good faith defending such claim or proceeding, the Indemnified Party shall not compromise or settle such claim without the prior written consent of the Indemnifying Party. If the Indemnifying Party does not assume the defense of any such claim or litigation in accordance with the terms hereof, the Indemnified Party may defend against such claim or litigation in such manner as it may deem appropriate, including, but not limited to, settling such claim or litigation (after giving notice of the same to the Indemnifying Party) on such terms as the Indemnified Party may deem appropriate, and the Indemnifying Party will promptly indemnify the Indemnified Party in accordance with the provisions of Section 10.1.

All representations, warranties, covenants, and obligations in this Agreement, the Disclosure Schedule, the certificate delivered pursuant to Section 8.7, and any other certificate or document delivered pursuant to this Agreement or any of the Related Documents will survive for a period of three years following the Closing; provided, however, that all representations and warranties made as of the date hereof by incorporation into this Agreement by reference pursuant to Section 4.17 of this Agreement that relate to Section 4.17 (Employment Matters) and Section 4.23 (Taxes) of the Securities Purchase Agreement shall survive until 30 days after the expiration of the respective statute of limitations applicable thereto. The right to indemnification, payment of Losses or other remedy based on such representations, warranties, covenants and agreements will not be affected by any investigation conducted with respect to, or any knowledge acquired (or capable of being acquired) at any time, whether before or after the execution and delivery of this Agreement or the Closing Date, with respect to the accuracy or inaccuracy of or compliance with, any such representation, warranty, covenant or agreement. The waiver of any condition based on the accuracy of any representation or warranty, or on the performance of or compliance with any covenant or obligation, will not affect the right to indemnification, payment of Losses, or other remedy based on such representations, warranties, covenants and agreements.

By notice given prior to the Closing, this Agreement may be terminated as follows:

(b) by Blue Ridge China as to itself and by EI as to itself, if a material breach of any provision of this Agreement has been committed by any Member of the Company Group, which breach shall not be cured within a period of five (5) Business Days of receipt of written notice thereof from such Purchaser;

(c) by the Company or the Management Shareholders, if a material breach of any provision of this Agreement has been committed by a Purchaser, which breach shall not be cured within a period of five (5) Business Days of receipt of written notice thereof from the Company or the Management Shareholders, which notice shall be sent to each of the Purchasers; provided that a breach by the Non-Closing Purchaser shall not entitle the Company or the Management Shareholders to terminate this Agreement if the Closing Purchaser notifies the Company within such five (5) Business-Day period that it intends to send the notice referred to in Section 9.9, or if the Closing Purchaser sends such notice within such five (5) Business-Day period; and

(d) by the Purchasers, the Management Shareholders or the Company if the Closing has not occurred on or before December 31, 2006, provided that such right of termination shall not be exercisable by any party which is then in material breach of this Agreement.

Each party’s right of termination under Section 11.1 is in addition to any other rights it may have under this Agreement or otherwise, and the exercise of such right of termination will not be an election of remedies. If this Agreement is terminated pursuant to Section 11.1, all obligations of the parties under this Agreement will terminate, except that the obligations of the parties in this Section 11.2 and Article 12 shall survive the termination of this Agreement; provided, that no such termination shall relieve any party of liability for any breach of this Agreement.

This Agreement, together with the Related Documents, merges all previous negotiations and agreements among the parties hereto, either oral or written, and constitutes the entire agreement and understanding among the parties with respect to the subject matter hereof and thereof. For the avoidance of doubt, the Securities Purchase Agreement and the Related Documents referred to therein shall remain in full force and effect except to the extent expressly modified by this Agreement or the Related Documents referred to herein.

No amendment, modification, or waiver of any provision of this Agreement shall be valid except by an agreement in writing executed by the parties hereto. Except as otherwise expressly set forth herein, no failure or delay by any party hereto in exercising any right, power or privilege hereunder (and no course of dealing between or among any of the parties) shall operate as a waiver of any such right, power or privilege. No waiver of any default on any one occasion shall constitute a waiver of any subsequent or other default. No single or partial exercise of any such right, power or privilege shall preclude the further or full exercise thereof.

If any provision of this Agreement or the application thereof to any Person or circumstance shall be invalid or unenforceable to any extent, the remainder of this Agreement and the application of such provision to other Persons or circumstances shall not be affected thereby and shall be enforced to the greatest extent permitted by Law, but only as long as the continued validity, legality and enforceability of such provision or application does not materially (a) alter the terms of this Agreement, (b) diminish the benefits of this Agreement or (c) increase the burdens of this Agreement, for any Person.

The rights and obligations of the parties hereunder shall be binding upon and inure to the benefit of the parties hereto, their successors and permitted assigns. This Agreement may not be assigned (by operation of Law or otherwise) without the prior written consent of the parties; provided, that any Purchaser may assign its rights and delegate its duties hereunder to any of its Affiliates upon written notice to the Company and the other Purchasers, which notice shall identify the assignee, so long as such Purchaser remains liable for the performance of such Affiliate.

Nothing herein, expressed or implied, is intended to or shall confer on any Person other than the parties hereto any rights, remedies, obligations or liabilities under or by reason of this Agreement.

All notices and other communications required or permitted to be given hereunder shall be in writing and shall be deemed to have been duly given if delivered in accordance with the provisions of Section 12.6 of the Securities Purchase Agreement, except that the address of the Company (including copy recipients) shall be deleted and replaced with the following address (it being agreed that the following address shall be deemed to replace the address of the Company (including copy recipients) in Section 12.6 of the Securities Purchase Agreement for all purposes of the Securities Purchase Agreement):

with required copies (which shall not by itself constitute notice) to the Purchasers and to the Management Shareholders at the addresses provided in Section 12.6 of the Securities Purchase Agreement (including copy recipients).

At the Closing, the Company shall reimburse the Purchasers for all of their reasonable costs and expenses, including the fees and expenses of any attorney or tax advisor retained by them, that they shall have incurred in connection with the legal, accounting and commercial due diligence process, the negotiation, execution, delivery and performance of this Agreement and the Related Documents and the consummation of the Transactions provided, that such reimbursement shall be limited to a maximum of $75,000. The Company or the Management Shareholders, as the case may be, shall also reimburse the Purchasers on demand for their reasonable costs (including attorneys’ fees and expenses) of enforcing any provision of this Agreement or the Related Documents in the event of a breach by any Member of the Company Group; provided, that such reimbursement shall be limited to a maximum of $250,000 per claim.

This Agreement shall be governed by and construed in accordance with the internal laws of the State of New York without application of principles of conflicts of law.

The parties agree that irreparable damage will occur in the event that either party fails to consummate the Transactions in accordance with the terms of this Agreement, and that the parties shall therefore be entitled to specific performance in such event, in addition to any other remedy at law or in equity.

Any dispute arising out of or relating to this Agreement, or the breach, termination or validity thereof, shall be resolved by arbitration in accordance with the provisions of Section 12.10 of the Securities Purchase Agreement. The parties hereby consent to the exclusive jurisdiction of (i) the Supreme Court of the State of New York and the United States District Court for the Southern District of New York, and (ii) courts with appropriate jurisdiction to hear such matters in Hong Kong, Special Administrative Region, for temporary injunctive or other relief in aid of arbitration or to prevent irreparable harm and to the non-exclusive jurisdiction of such courts for enforcement of any award by the arbitrators.

As both parties have participated in the drafting of this Agreement, any ambiguity shall not be construed against either party as the drafter. Unless the context of this Agreement clearly

requires otherwise, (a) “or” has the inclusive meaning frequently identified with the phrase “and/or”, (b) “including” has the inclusive meaning frequently identified with the phrase “including, but not limited to,” (c) references to “hereof,” “hereunder” or “herein” or words of similar import relate to this Agreement, (d) when a reference is made in this Agreement to an Article or a Section, such reference shall be to an Article or a Section of this Agreement unless otherwise indicated, and (e) the terms defined hereunder shall have the meanings therein specified for all purposes of this Agreement, applicable to both the singular and plural forms of any of the terms defined herein. The section headings contained in this Agreement are solely for the purpose of reference, are not part of the agreement of the parties and shall not in any way affect the meaning or interpretation of this Agreement. All terms and words used in this Agreement, regardless of the number and gender in which they are used, shall be deemed and construed to include any other number and any other gender as the context of this Agreement requires.

This Agreement may be executed in two or more counterparts, each of which when so executed shall be an original, but all of which together shall constitute one agreement. Facsimile signatures shall be deemed original signatures.

No Member of the Company Group shall, and each Member of the Company Group shall cause their respective affiliates and advisors, and their respective directors, officers and representatives not to, disclose to anyone the fact that the Purchasers have executed this Agreement, or disclose to or discuss with anyone the terms of this Agreement, without the prior written consent of the Purchasers, except to their officers and advisors, as necessary, provided that they agree to maintain the confidentiality thereof, and except as may be necessary to consummate the Transactions.

IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of the date first above written.
