3.06, shall be (i) $76,000,000 USD (the “Initial Consideration”); and (ii) the Earnout Amount, if any (together with the Initial Consideration, the “Merger Consideration”), which shall be allocated among the Series A Shareholders and Ordinary Shareholders as set forth in Section 3.03(a).

Section 3.02 Payment of Merger Consideration. The Merger Consideration shall be paid by Parent as follows:

(a) Application of Target Company Cash Prior to Payment of Initial Consideration.

(a) the portion of all outstanding and unpaid obligations and indebtedness, together with interest, fees and premiums, if any, with respect to the Company Debt Arrangements which remains outstanding and unpaid by the Company as of the Effective Time which shall be paid to the relevant lenders of such indebtedness (the “Debt Payoff”); and

(b) the amount of all obligations for legal, accounting, advisory and all other obligations of the Company incurred in connection with the negotiation and delivery of this Agreement and the consummation of the transactions contemplated by this Agreement (collectively, “Company Transaction Expenses”). For the avoidance of doubt with respect to the Company Transaction Expenses, it is understood and agreed that any Company Transaction Expenses incurred after the Effective Time shall be borne by the Ordinary Shareholders on a per share basis based upon all outstanding Ordinary Shares.

(ii) The amount of any Debt Payoff or Company Transaction Expenses not paid in full under Section 3.02(a)(i) (the “Closing Cash Deficiency”) will be deducted and paid from the Initial Consideration as set forth in Section 3.02(b)(i).

(b) Initial Consideration. At the Effective Time, the payment of the Initial Consideration by Parent shall be as follows:

(ii) an amount equal to the Series A Redemption Amount shall be paid pro rata on a per share basis to the Series A Shareholders, subject to the terms and conditions of Section 3.04 to the extent applicable; and

(iii) the Initial Consideration less (y) the Closing Cash Deficiency, and (z) the Series A Redemption Amount (collectively, the “Net Initial Consideration”) shall be paid pro rata on a per share basis to the Ordinary Shareholders entitled to the Per Share Merger Consideration, subject to the terms and conditions of Section 3.04. The Net Initial Consideration shall be paid by Parent in the form of II-VI Shares and cash as follows:

(a) the number of II-VI Shares (rounded up to the next whole share) issuable as Net Initial Consideration shall be equal to the quotient of (x) $30,400,000 USD, divided by (y) the lesser of (A) $26.53 (the average closing day trading price of the II-VI Shares for the 90 consecutive trading days ending on November 30, 2009) or (B) the average closing day trading price of the II-VI Shares for the 90 consecutive trading days ending on the date that is five Business Days prior to the Closing Date (the “Closing Share Price”); provided, however, that the number of II-VI Shares shall be reduced by the aggregate amount of all fractional II-VI Shares which are paid in cash to the Ordinary Shareholders as set forth in Section 3.04(c); and

(b) the Net Initial Consideration less $30,400,000 USD shall be paid in cash; provided, however, that the amount of cash shall be increased to the extent necessary to pay cash to Ordinary Shareholders in lieu of fractional II-VI Shares as set forth in Section 3.04(c).

(c) Earnout. The payment of the Earnout Amount shall by made by Parent at the time and subject to the terms and conditions set forth in Section 3.05.

(b) At the Effective Time, the Series A Shareholders and Ordinary Shareholders shall cease to be, and shall have no rights as, shareholders of the Company, other than the right to receive the Series A Redemption Amount or the Per Share Merger Consideration, as the case may be.

(c) Each ordinary share, par value $1.00 per share, of Merger Sub issued and outstanding immediately prior to the Effective Time shall be unchanged and shall remain issued and outstanding as one fully paid ordinary share of the Surviving Corporation.

Section 3.04 Exchange Procedures.

(a) Prior to the Effective Time, Parent shall engage at its sole expense American Stock Transfer & Trust Company, II-VI’s transfer agent, as agent (the “Paying Agent”) for the purpose of exchanging the Merger Consideration to be paid pursuant to Section 3.01 for Shares. The Company agrees to Parent’s engagement of American Stock Transfer & Trust Company, II-VI’s transfer agent, as the Paying Agent. Not less than five Business Days prior to the Effective Time, Parent shall have received from each of the Ordinary Shareholders (other than holders of Dissenting Shares) and Series A Shareholders, a letter of transmittal and

instructions (in a form reasonably acceptable to Parent and the Company), which, (i) in the case of Ordinary Shareholders, shall include, among other things, an acknowledgement and agreement to be bound by the provisions of Section 3.04(d) [Lockup], Section 6.10 [Shareholder Representative] and Article XI [Survival; Indemnification] and to make the representations and warranties contained in Article VII [Securities Matters] of this Agreement, and (ii) in the case of the Series A Shareholders, shall include, among other things, a waiver and release as more fully set forth therein, for use in such exchange (collectively, the “Letters of Transmittal”). The Letters of Transmittal for Series A Shareholders and for Ordinary Shareholders will substantially be in the forms attached as Exhibits C-1 and C-2, respectively.

(b) After the Effective Time and subject to the receipt by the Parent of a Letter of Transmittal duly completed and validly executed in accordance with the instructions thereto, (i) the Series A Shareholder or Ordinary Shareholder, as the case may be, shall be entitled to receive the Series A Redemption Amount or Per Share Merger Consideration, as applicable, for each Share and (ii) each Share shall immediately be canceled and reflected as such in the register of members of the Surviving Corporation. Subject to satisfaction of the conditions set forth in the preceding sentence, the Buyer Parties shall cause the Paying Agent to pay any Series A Redemption Amount or Per Share Merger Consideration, as the case may be, payable pursuant to this Agreement to the former holder of such Share as soon as reasonably practicable after the Effective Time, but in no event later than two (2) Business Days following the Effective Time, in the manner as described in the following sentence. The Series A Redemption Amount and the cash portion of the Per Share Merger Consideration shall be paid to the former holder by check or wire transfer of immediately available funds (as specified by such former holder in the Letter of Transmittal) and the II-VI Shares shall be delivered to the former holder at such former holder’s mailing address (as specified by such former holder in the Letter of Transmittal) in the form of duly executed certificates representing such II-VI Shares. Until so surrendered, each outstanding Share prior to the Effective Time will be deemed from and after the Effective Time, for all purposes, to evidence only the right to receive upon its surrender the Series A Redemption Amount or Per Share Merger Consideration, as the case may be, for each Share pursuant to Section 3.03(a).

(c) The portion of the Per Share Merger Consideration comprised of the pro rata Net Initial Consideration will be paid to each Ordinary Shareholder under this Section 3.04 in cash and II-VI Shares in the same proportion of cash and II-VI Shares paid by Parent to the Paying Agent, provided that (i) Parent may direct that certain Ordinary Shareholders solely receive cash for the Net Initial Consideration portion of the Ordinary Shareholder’s Per Share Merger Consideration if the issuance of II-VI Shares to such Ordinary Shareholder could require registration of the II-VI Shares or a filing with any Governmental Authority and (ii) any Ordinary Shareholder entitled to a fractional II-VI Share shall be paid in cash in lieu of the fractional share.

(d) No Ordinary Shareholder may (i) offer, sell, contract to sell, transfer, gift, pledge or otherwise dispose of any II-VI Shares comprising the Net Initial Consideration or enter into any transaction which is designed to, or might reasonably be expected to, result in any disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise) by such Ordinary Shareholder, directly or indirectly, or (ii) establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the

meaning of Section 16 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules and regulations of the SEC promulgated thereunder, with respect to any such II-VI Shares (the “Lockup”). For each Ordinary Shareholder, the Lockup will expire as to fifty percent of such Ordinary Shareholder’s pro rata portion of the II-VI Shares comprising the Net Initial Consideration on the date that is six months after the Closing Date and will expire as to such Ordinary Shareholder’s remaining II-VI Shares comprising the Net Initial Consideration on the date that is twelve months after the Closing Date. No waiver of this provision may be granted, except in compliance with Regulation D of the Securities Act of 1933, as amended (the “Securities Act”), or Regulation S of the Securities Act, as applicable.

(e) Any portion of the Merger Consideration that remains undistributed to Shareholders as of the date that is 180 days after the date of the Closing Date shall be delivered to Parent upon demand, and Series A Shareholders or Ordinary Shareholders, as the case may be, who have not theretofore surrendered their Shares in accordance with this Section 3.04 shall thereafter look only to Parent for satisfaction of their claims for any Series A Redemption Amount or Per Share Merger Consideration, as the case may be, payable with respect to the Shares, without any interest thereon.

(f) Neither Parent nor the Surviving Corporation shall be liable to any Series A Shareholder or Ordinary Shareholder, as the case may be, for the Series A Redemption Amount or Per Share Merger Consideration, as the case may be, attributable to such Shares or for any other amounts delivered to any public official pursuant to any applicable abandoned property, escheat or similar law. Any amounts remaining unclaimed by Series A Shareholders and/or Ordinary Shareholders three years after the Effective Time (or such earlier date immediately prior to such time as such amounts would otherwise escheat to or become property of any Governmental Authority) shall, to the extent permitted by Law, become the property of Parent free and clear of any Lien.

Section 3.05 Earnout.

(a) Payment. Subject to the terms and conditions of this Agreement, on or prior to 90 days after the end of each Earnout Period, Parent shall deliver to the Paying Agent for distribution to the Ordinary Shareholders entitled to receive Per Share Merger Consideration the Revenue-Based Earnout Amount and the Earnings-Based Earnout Amount (collectively, the “Earnout Amount”) for the Earnout Period, as determined in accordance with Schedule 3.05, subject to any adjustments provided for under Article XI [Survival; Indemnification].

(b) Statement of Earnout. Within 30 days of the end of each Earnout Period, Parent shall prepare or cause to be prepared a statement (an “Earnout Statement”) setting forth the calculation of the Earnout Amount for the Earnout Period including the calculation of Earnings and Revenue, subject to any adjustments provided for under Article XI [Survival; Indemnification] (collectively, the “Earnout Results”) and deliver the Earnout Statement to the Shareholder Representative who will be deemed to have received the Earnout Statement for and on behalf of all of the Ordinary Shareholders entitled to receive Per Share Merger Consideration.

(c) Dispute Resolution. If the Shareholder Representative does not agree with the Earnout Results set forth in the Earnout Statement, then within 30 days after the delivery to

the Shareholder Representative of the Earnout Statement, the Shareholder Representative shall deliver to the Parent a written notice (an “Objection Notice”) describing in reasonable detail the Shareholder Representative’s objections to the Earnout Statement and setting forth the Earnout Results determined by the Shareholder Representative to be correct. During such 30-day period, the Shareholder Representative shall be permitted to review the working papers of Parent relating to the Earnout Statement and Parent and the Company shall, and shall cause their respective accountants to, cooperate and assist in the conduct of the review by the Shareholder Representative, including by providing reasonable access to the extent necessary of books, records and personnel. Parent and Shareholder Representative shall use good faith efforts to resolve any disputed items and if no agreement is reached within 15 days of the Parent’s receipt of the Objection Notice, the matter shall be submitted to arbitration pursuant to Section 12.07 of this Agreement. If the Shareholder Representative does not deliver a timely Objection Notice to the Parent, then the Parent’s calculation of the Earnout Results shall be binding and conclusive on the Parent, the Shareholder Representative and all of the Ordinary Shareholders entitled to receive the Earnout Amount portion of the Per Share Merger Consideration.

(d) Contractual. The right to receive any Earnout Amount (i) is solely a contractual right and is not a security (and shall confer upon the Ordinary Shareholders only the rights of a general unsecured creditor); (ii) will not be represented by any form of certificate or instrument; (iii) does not give the Ordinary Shareholder any dividend rights, voting rights, liquidation rights, preemptive rights or other rights; and (iv) is not redeemable.

Section 3.06 Post-Closing Adjustments. The aggregate consideration payable pursuant to the Merger shall be subject to the following adjustments:

(a) Net Working Capital Adjustment.

(i) After the Closing, Parent and the Shareholder Representative shall determine the Net Working Capital of the Target Companies as of December 31, 2009 in accordance with the provisions of this Section 3.06(a). For purposes of this Agreement, “Net Working Capital” shall mean the (i) current assets of the Target Companies on a consolidated basis as of December 31, 2009, less (ii) current liabilities of the Target Companies on a consolidated basis as of December 31, 2009, determined in accordance with U.S. GAAP. The Net Working Capital shall be calculated in the same manner and using the same methods as the calculation of net working capital dated June 30, 2009, a copy of which is attached as Exhibit D, subject to the following adjustments:

(a) all Target Company Cash shall be excluded; and

(b) all of the Company Debt Arrangements, Option Repurchase Amounts and Company Transaction Expenses shall be excluded; and

(c) the Net Working Capital as of December 31, 2009 shall be calculated without regard to year-end adjustments for bad debts and inventory adjustments except that the Net Working Capital as of December 31, 2009 shall be adjusted by the Year-End Adjustment Amount (as defined below).

(ii) Within 75 days of Closing and subject to adjustment based upon the audit of the consolidated financial statements of the Company as of December 31, 2009 as provided in Section 3.06(a)(iii) below, the Company shall calculate year-end adjustments for bad debts and inventory adjustments for (1) the period beginning January 1, 2009 and ending as of June 30, 2009 (the “Mid-Year Adjustment Amount”); and (2) the period beginning July 1, 2009 and ending as of December 31, 2009 (the “Year-End Adjustment Amount”). The Mid-Year Adjustment Amount and Year-End Adjustment Amount shall be calculated in accordance with U.S. GAAP and consistent with past practices except that the Mid-Year Adjustment Amount shall be calculated in the same manner as if June 30, 2009 was the last day of the tax year.

(iii) Within 75 days after the Closing, Parent shall prepare or cause to be prepared a statement (the “Statement of Net Working Capital”) based on the audit of the consolidated financial statements of the Company as of December 31, 2009 setting forth the calculation of Net Working Capital and deliver the Statement of Net Working Capital to the Shareholder Representative who will be deemed to have received it for and on behalf of all of the Ordinary Shareholders entitled to receive Per Share Merger Consideration.

(iv) If the Shareholder Representative does not agree with the Statement of Net Working Capital, then within 15 days after the delivery to the Shareholder Representative of the Statement of Net Working Capital, the Shareholder Representative shall deliver to the Parent an objection notice (the “Net Working Capital Objection Notice”) describing in reasonable detail the Shareholder Representative’s objections to the Statement of Net Working Capital and the basis therefore. During such 15 day period, the Shareholder Representative shall be permitted to review the working papers of Parent relating to the Statement of Net Working Capital and Parent and the Surviving Corporation shall, and shall cause their respective accountants to, cooperate and assist in the conduct of the review by the Shareholder Representative, including by providing reasonable access to the extent necessary of books, records and personnel. Parent and Shareholder Representative shall use good faith efforts to resolve any disputed items and if no agreement is reached within 15 days of the Parent’s receipt of the Net Working Capital Objection Notice, the matter shall be submitted to arbitration pursuant to Section 12.07 of this Agreement. If the Shareholder Representative does not deliver a timely Net Working Capital Objection Notice to the Parent, then the calculation of Net Working Capital set forth in Parent’s Statement of Net Working Capital shall be binding and conclusive on the Parent, the Shareholder Representative and all of the Ordinary Shareholders entitled to receive Per Share Merger Consideration.

(v) If the Net Working Capital of the Target Companies is less than $13,965,000 minus the Mid-Year Adjustment Amount (the “Net Working Capital Base Amount”), the aggregate Merger Consideration shall be reduced by the difference between the Net Working Capital Base Amount and the Net Working Capital (the “Net Working Capital Downward Adjustment”). Any Net Working Capital Downward Adjustment shall be deemed to be a Parent Loss and subject to setoff under Section 11.05 of this Agreement. Notwithstanding the foregoing, there will be no reduction to the aggregate Merger Consideration under this Section 3.06(a)(v) and no Net Working Capital Downward Adjustment shall be payable by the Ordinary Shareholders if the Net Working Capital Downward Adjustment is less than $250,000; provided that the entire amount of the Net Working Capital Downward Adjustment shall be payable if the amount exceeds $250,000.

(vi) If the Net Working Capital of the Target Companies is greater than the Net Working Capital Base Amount, the aggregate Merger Consideration shall be increased by the difference between the Net Working Capital and the Net Working Capital Base Amount (on a per share basis, the “Net Working Capital Upward Adjustment”). Any Net Working Capital Upward Adjustment shall be paid by Parent to the Paying Agent within 10 days after the final determination of the Net Work Capital pursuant to this Section 3.06(a) for distributions to the Ordinary Shareholders entitled to receive Per Share Merger Consideration. Notwithstanding the foregoing, there will be no increase to the aggregate Merger Consideration under this Section 3.06(a)(vi) and no Net Working Capital Upward Adjustment shall be payable by Parent if the Net Working Capital Upward Adjustment is less than $250,000, provided that the entire amount of the Net Working Capital Upward Adjustment shall be payable if the amount exceeds $250,000.

(b) Net Cash Adjustment.

(i) After the Closing, Parent and the Shareholder Representative shall determine the Net Cash of the Target Companies as of December 31, 2009 in accordance with the provisions of this Section 3.06(b). For purposes of this Agreement, “Net Cash” shall mean (i) the Target Company Cash as of December 31, 2009, less (ii) the Company Transaction Expenses not paid as of December 31, 2009, less (iii) any Option Repurchase Amounts not paid as of December 31, 2009, less (iv) the Company Debt Arrangements not paid as of December 31, 2009.

(ii) Within 75 days after the Closing, Parent shall prepare or cause to be prepared a statement (the “Statement of Net Cash”) based on the audit of the consolidated financial statements of the Company as of December 31, 2009 setting forth the calculation of Net Cash and deliver the Statement of Net Cash to the Shareholder Representative who will be deemed to have received it for and on behalf of all of the Ordinary Shareholders entitled to receive Per Share Merger Consideration.

(iii) If the Shareholder Representative does not agree with the Statement of Net Cash, then within 15 days after the delivery to the Shareholder Representative of the Statement of Net Cash, the Shareholder Representative shall deliver to the Parent an objection notice (the “Net Cash Objection Notice”) describing in reasonable detail the Shareholder Representative’s objections to the Statement of Net Cash and the basis therefore. During such 15 day period, the Shareholder Representative shall be permitted to review the working papers of Parent relating to the Statement of Net Cash and Parent and the Surviving Corporation shall, and shall cause their respective accountants to, cooperate and assist in the conduct of the review by the Shareholder Representative, including by providing reasonable access to the extent necessary of books, records and personnel. Parent and Shareholder Representative shall use good faith efforts to resolve any disputed items and if no agreement is reached within 15 days of the Parent’s receipt of the Net Cash Objection Notice, the matter shall be submitted to arbitration pursuant to Section 12.07 of this Agreement. If the Shareholder Representative does not deliver a timely Net Cash Objection Notice to the Parent, then the calculation of Net Cash set forth in Parent’s Statement of Net Cash shall be binding and conclusive on the Parent, the Shareholder Representative and all of the Ordinary Shareholders entitled to receive Per Share Merger Consideration.

(iv) If the Net Cash of the Target Companies is less than zero, the aggregate Merger Consideration shall be reduced by the positive difference between the Net Cash and zero (the “Net Cash Downward Adjustment”). Any Net Cash Downward Adjustment shall be deemed to be a Parent Loss and subject to setoff under Section 11.05 of this Agreement.

(v) If the Net Cash of the Target Companies is greater than zero, the aggregate Merger Consideration shall be increased by the positive difference between the Net Cash and zero (on a per share basis, the “Net Cash Upward Adjustment”). Any Net Cash Upward Adjustment shall be paid by Parent to the Paying Agent within 10 days after the final determination of the Net Cash pursuant to this Section 3.06(b) for distributions to the Ordinary Shareholders entitled to receive Per Share Merger Consideration.

Section 3.07 Withholding. Each of Parent, the Surviving Corporation and the Paying Agent shall be entitled to deduct and withhold from the amounts otherwise payable pursuant to this Article III to any Shareholder such amounts as it may be required to deduct and withhold with respect to the making of such payment, provided that no amount shall be withheld in respect of PRC Taxes. To the extent that amounts are so deducted and withheld, such withheld amount shall be treated for all purposes of this Agreement as having been paid to the Shareholder on whose behalf such deduction and withholding are made.

Section 3.08 Dissenting Shares. Notwithstanding any provision of this Agreement to the contrary, any Shares that are outstanding immediately prior to the Effective Time and that are held by any Series A Shareholder or Ordinary Shareholder, as the case may be, who has not voted in favor of the Merger or consented thereto in writing and who has demanded properly in writing an appraisal for such Shares in accordance with Section 238 of the Companies Law (collectively, the “Dissenting Shares”) will not be converted into or represent the right to receive the Series A Redemption Amount or Per Share Merger Consideration, as the case may be, into which the Shares held by such Shareholder otherwise would have been converted pursuant to this Article III. Such Series A Shareholders and/or Ordinary Shareholders, as the case may be, holding Dissenting Shares will be entitled to receive payment of the appraised value of such Dissenting Shares held by them in accordance with the provisions of such Section 238, which shall be, subject to the Cayman court’s determination of the fair value pursuant to such Section 238 of the Companies Law, payable in the form of cash and II-VI Shares in the same proportion as Per Share Merger Consideration, except that all Dissenting Shares held by Series A Shareholders and/or Ordinary Shareholders, as the case may be, who will have failed to perfect or who effectively will have withdrawn or lost their rights to appraisal of such Shares under such Section 238 will thereupon be deemed to have been converted into and to have become exchangeable for, as of the Effective Time, the right to receive the Series A Redemption Amount or Per Share Merger Consideration, as the case may be, payable pursuant to this Article III, subject to the terms and conditions of Section 3.04 to the extent applicable.

REPRESENTATIONS AND WARRANTIES OF BUYER PARTIES

The Buyer Parties hereby jointly and severally represents and warrants to the Company and the Ordinary Shareholders that, except as qualified by disclosure in the SEC Documents (as defined below) if such qualification is expressly set forth in the applicable Section and subsection of this Article V and to the extent the qualifying nature of such disclosure is readily apparent on its face, but excluding any disclosure in such SEC Documents to the extent that it is predictive,

cautionary or forward-looking in nature (it being understood and agreed that facts underlying such predictive, cautionary or forward-looking statements shall not be excluded to the extent those facts are stated in such SEC Documents and in existence on the date of such SEC Documents), as of the date hereof and as of the Closing Date:

Section 5.01 Corporate Matters.

(a) Organization, Power and Standing. Each Buyer Party is a corporation duly incorporated, validly existing and in good standing under the laws of the jurisdiction of its incorporation and has all requisite power and authority to execute, deliver and perform this Agreement, including, without limitation, to issue the II-VI Shares to the Ordinary Shareholders in accordance with the terms hereof, to own its property, to carry on its business as it is now conducted, and to consummate the transactions contemplated hereby. Each Buyer Party is duly qualified to transact business in each jurisdiction where its ownership or leasing of assets or conduct of its business requires it to be so qualified or licensed, except where the failure to do so would not have a Material Adverse Effect.

(b) Authorization and Enforceability. This Agreement has been duly authorized, executed and delivered by each Buyer Party and, assuming the due authorization, execution and delivery by the other parties hereto, is the legal, valid and binding obligation of the Buyer Party, enforceable against the Buyer Party in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization or other laws affecting creditors’ rights generally and general principles of equity (whether considered in a proceeding at law or in equity).

(c) Capitalization. The authorized share capital of the Merger Sub consists of $50,000 divided into 50,000 ordinary shares of US$1.00 par value each (“MS Ordinary Shares”), of which 1,000 MS Ordinary Shares are issued and outstanding. The capitalization of II-VI as of September 30, 2009, including its authorized capital stock and the number of shares issued and outstanding is as set forth in its Quarterly Report on Form 10-Q for the Quarter ended September 30, 2009.

All issued and outstanding shares of capital stock of II-VI have been, or upon issuance will be, validly issued, fully paid and non-assessable. No shares of capital stock of II-VI were issued in violation of any preemptive rights or any other similar rights of security holders of II-VI. Except as disclosed in the SEC Documents (as defined below), there are no outstanding preemptive rights, rights of first refusal, shareholder rights, options, warrants, scrip, rights to subscribe to, calls or commitments of any capital stock of II-VI, or arrangements by which II-VI is or may become (as a result of the transactions contemplated hereby or otherwise) bound to issue additional shares or capital stock of II-VI (whether pursuant to anti-dilution, “reset” or other similar provisions).

(d) Non-Contravention. Neither the execution and delivery of this Agreement by a Buyer Party nor the consummation by the Buyer Party of the transactions contemplated hereby does or will constitute or give rise to a violation of any Contractual Obligation or the Constituent Documents of the Buyer Party or a violation of any Law applicable to the Buyer Party or the imposition of any Lien upon or the forfeiture of any asset of the Buyer Party

(including, for such purposes, any such asset held under a lease or license). No approval, consent, waiver, authorization or other order of, and no declaration, filing, registration, qualification or recording with, a Governmental Authority is required to be obtained or made by or on behalf of such Buyer Party in connection with the execution, delivery and performance of this Agreement by the Buyer Party of its obligations under this Agreement, except where failure to obtain such approval, consent, waiver, authorization or other order, or to make such declaration, filing, registration, qualification or recording, would not adversely affect the Buyer Party’s ability to consummate the Closing hereunder in accordance with the terms and conditions of this Agreement and would not prevent the Buyer Party from performing in all material respects any of its other obligations under this Agreement.

Section 5.02 Litigation. There is no Action pending or to each Buyer Party’s Knowledge threatened in writing (a) against a Buyer Party or any of its Affiliates which has had or would reasonably be expected to have a Material Adverse Effect on the ability of the Buyer Party to perform its obligations under this Agreement or (b) which seeks rescission of or seeks to enjoin the consummation of this Agreement or any of the transactions contemplated hereby. There is no material claim, litigation or administrative proceeding pending or, to each Buyer Party’s Knowledge, threatened or contemplated, against II-VI or, to each Buyer Party’s Knowledge, against any officer, director or employee of II-VI in connection with such Person’s employment therewith, except as described in the SEC Documents and except for matters that are not required to be disclosed in the SEC Documents. II-VI is not a party to or subject to the provisions of, any order, writ, injunction, judgment or decree of any court or Governmental Authority which has had or would reasonably be expected to have a Material Adverse Effect.

Section 5.03 Brokers. Except for DRP Financial Advisors (Xxxxxx X. Xxxxx, Xx.), no broker, finder, investment bank or similar agent is entitled to any brokerage or finder’s fee in connection with the transactions contemplated by this Agreement based upon agreements or arrangements made by or on behalf of a Buyer Party or any of its Affiliates.

Section 5.04 Valid Issuance. The II-VI Shares are duly authorized and, when issued and delivered in accordance with the terms hereof, (i) the II-VI Shares will be duly and validly issued, and the II-VI Shares will be fully paid and nonassessable free and clear of any Liens imposed by or through any of the Buyer Party and (ii) assuming the accuracy of the Ordinary Shareholders’ representations in Article VII of this Agreement, the II-VI Shares will be issued and delivered in compliance with all applicable federal and state securities laws.

Section 5.05 Disclosure Documents; Agreements; Financing Statements; Other Information. II-VI is subject to the reporting requirements of the Exchange Act and has filed with the Commission all reports, schedules, registration statements and definitive proxy statements that II-VI was required to file with the Commission on or after December 31, 2008 and will be required to file with the Commission prior to the Effective Time (collectively, the “SEC Documents”). Each SEC Document, as of the date of the filing thereof with the Commission (or if amended or superseded by a filing prior to the date hereof, then on the date of such amending or superseding filing), complied in all material respects with the requirements of the Securities Act or Exchange Act, as applicable, and the rules and regulations promulgated thereunder and, as of the date of such filing (or if amended or superseded by a filing prior to the date hereof, then on the date of such filing), such SEC Document (including all exhibits and schedules thereto and

documents incorporated by reference therein) did not contain an untrue statement of material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. All documents required to be filed as exhibits to the SEC Documents have been filed as required. Except as set forth in the SEC Documents, II-VI has no liabilities, contingent or otherwise, other than liabilities incurred in the ordinary course of business which, under U.S. GAAP, are not required to be reflected in the financial statements included in the SEC Documents and which, individually or in the aggregate, are not material to the business or financial condition of II-VI. As of their respective dates, the financial statements of II-VI included in the SEC Documents have been prepared in accordance with U.S. GAAP (except (i) as may be otherwise indicated in such financial statements or the notes thereto, or (ii) in the case of unaudited interim statements, to the extent they may exclude footnotes or may be condensed or summary statements) and fairly present in all material respects the financial position of II-VI as of the dates thereof and the results of its operations and cash flows for the periods then ended (subject, in the case of unaudited statements, to normal year-end adjustments).

Section 5.06 Exchange Act Registration; Listing. II-VI files supplementary and periodic information, documents and reports pursuant to Section 13 of the Exchange Act. II-VI’s common stock is registered pursuant to Section 12(b) of the Exchange Act and is listed on the Nasdaq Global Market. II-VI currently meets the continuing eligibility requirements for listing on the Nasdaq Global Market and has not received any notice from such market or the FINRA that it does not currently satisfy such requirements or that such continued listing is in any way threatened. II-VI has taken no action designed to, or which would reasonably be expected to have the effect of, terminating the registration of the common stock under the Exchange Act or delisting the common stock from the Nasdaq Global Market.

Section 5.07 Financial Condition II-VI’s financial condition is, in all material respects, as described in the SEC Documents, except for changes in the ordinary course of business. As of the date of this Agreement, except for changes in the ordinary course of business, since September 30, 2009 there has been no (i) material adverse change to II-VI’s business, operations, properties, financial condition, or results of operations or (ii) change by II-VI in its accounting principles, policies and methods except as required by changes in the U.S. GAAP or applicable Law.

Notwithstanding the foregoing and for the avoidance of doubt, the parties have reached the following agreements:

(a) Credit Facility Retention. Although the Company will satisfy all outstanding amounts under the Company Debt Arrangements so that there are no outstanding balances or obligations of any kind under such facilities as of the Effective Time, the Company may leave the unsecured line of credit listed on Schedule 6.07 open for use by the Company after Closing as provided for in Schedule 6.07.

(b) Option Repurchase Amount. Although the Company intends to satisfy the Option Repurchase Amount so that there are no outstanding balances or obligations of any kind to the holders of Options as of the Effective Time, the Company shall not be required to complete the payment of the full Option Repurchase Amount prior to the Effective Time.

participants over a three year period from the Closing Date. The Retention Program will require compliance with State Administration of Foreign Exchange 78 circular registration.

A portion of the Retention Program equal to 20% of the value of the Retention Program will be in the form of phantom stock which will be awarded to participants on or shortly after the Closing Date and cashed out on the date that is six months from the Closing Date. The Retention Program shall provide that any participant whose employment is terminated voluntarily or for cause will forfeit his or her unvested/unearned award at the time of such termination.

Section 6.10 Shareholder Representative.

(a) Appointment. As evidenced by such Shareholder’s execution of a Letter of Transmittal or acceptance of any Per Share Merger Consideration pursuant to Article III, each of the Ordinary Shareholders hereby appoints Loyal Excel Investments Limited as the Shareholder Representative (the “Shareholder Representative”) to act as the exclusive agent, proxy and attorney-in-fact for the Shareholders for all purposes under this Agreement. Without limiting the generality of the foregoing, the Shareholder Representative is authorized and empowered to:

(i) take all actions on behalf of each Ordinary Shareholder in connection with any claims made under this Agreement to defend or settle such claims and to make or receive and disburse payments in respect of such claims;

(ii) make payments of the Earnout Amount to the Ordinary Shareholders in accordance with this Agreement;

(iii) establish such reserves as the Shareholder Representative may from time to time determine, in its sole discretion, to be necessary and desirable in connection with the expenses and other costs to be borne by the Shareholder Representative or the Ordinary Shareholders hereunder, and to pay such reserves from the Earnout Amount or direct the Buyer Parties to make payment of such amounts to be applied to such reserves in lieu of the payment to the Ordinary Shareholders hereunder; and

(iv) take all other actions to be taken by or on behalf of any Ordinary Shareholder and exercise any and all rights that any Ordinary Shareholder is permitted or required to do or exercise under this Agreement.

(b) Actions Binding. All decisions and actions by the Shareholder Representative will be binding upon each Ordinary Shareholder and no Ordinary Shareholder will have the right to object, dissent, protest or otherwise contest the same. The Buyer Parties will be able to rely conclusively on the written instructions of the Shareholder Representative (including any written instructions of any person purporting to be a duly authorized representative of the Shareholder Representative unless the Buyer Parties have actual knowledge to the contrary) as to such decisions and actions taken by the Shareholder Representative hereunder.

(c) Liability. The Shareholder Representative will not be liable for any action taken by the Shareholder Representative in good faith pursuant to this Agreement, and shall only be liable for acts or omissions which constitute gross negligence or intentional misconduct of the Shareholder Representative. The Shareholder Representative will be entitled to be compensated by the Ordinary Shareholders for any and all actions, liabilities, losses, damages, fines, penalties, fees, costs, expenses or amounts to or against the Shareholder Representative (in each case, including reasonable attorneys’ fees and expenses), whether or not involving a third party, arising as a result of its serving as the Shareholder Representative, including those incurred by the Shareholder Representative or the Affiliates of the Shareholder Representative or any agents or representatives of the Shareholder Representative or such Affiliates in connection with the protection, defense, enforcement or other exercise of any rights under this Agreement. The Shareholder Representative is serving in that capacity solely for purposes of administrative convenience, and is not personally liable in such capacity for any of the obligations of the Company or the Ordinary Shareholders hereunder and the Buyer Parties agree that they will not look to the Shareholder Representative, acting in such capacity, for the satisfaction of any obligations to be performed by the Company or the Ordinary Shareholders hereunder.

Section 6.11 Business Records. The Buyer Parties acknowledge that the Shareholder Representative, on behalf of the Ordinary Shareholders, may from time to time from and after the Closing Date require access to copies of books, records and such other information of the Target Companies as the Shareholder Representative may reasonably request, and agree that upon reasonable prior notice the Surviving Corporation will, and will ensure that the Target Companies will, during normal business hours, provide the Shareholder Representative with either access to or copies of such books, records and other information reasonably requested by the Shareholder Representative.

Section 6.12 Tax Matters.

(a) The Shareholders or the Shareholder Representative shall prepare, or cause to be prepared, and file, or cause to be timely filed, all Tax Returns of the Target Companies for all tax periods ending on or prior to the Closing Date (a “Pre-Closing Period”) that are required to be filed before the Closing Date and shall pay all Taxes due with respect to the Company and its Subsidiaries, or as to which the Company and its Subsidiaries are otherwise liable, for such Pre-Closing Period Tax Returns (except to the extent such Taxes were taken into account in calculating the Net Working Capital). Parent and Surviving Corporation shall prepare, or cause to be prepared, and timely file, or cause to be timely filed, all other Tax Returns of the Target Companies, including for all taxable periods beginning prior to the Closing Date and ending after the Closing Date (a “Straddle Period”), and shall pay all Taxes with respect thereto. Tax returns for any Pre-Closing or Straddle Period shall be prepared in a manner consistent with past practice.

(b) Where applicable Law does not permit the parties to elect to treat a Straddle Period as a short taxable period ending as of the close of business on the Closing Date, then, for purposes of this Agreement, the taxable income of the Target Companies for the entire taxable period shall be allocated between the Pre-Closing Period and the remainder of the taxable period using an interim-closing-of-the-books method, assuming that such taxable period ended at the close of business on the Closing Date and treating such period as a Pre-Closing Period for purposes of this Agreement, except that exemptions, allowances and deductions calculated on an annual basis shall be apportioned on a per diem basis.

(c) From and after the Effective Time, each of Parent, the Surviving Corporation and the Ordinary Shareholders shall cooperate fully with each other in connection with the preparation of any Tax Return or any Tax audit or other judicial or administrative proceeding relating to any Tax (a “Tax Claim”), and each will retain and provide the other with any records or information that may be relevant to such Tax Return or Tax Claim. The party requesting assistance hereunder shall reimburse the other for reasonable direct expenses incurred in providing such assistance. The Shareholder Representative shall have the right to review any Tax Return for any Pre-Closing Period or Straddle Period to be filed after the Closing Date prior to the filing of such return and Parent shall make any reasonable changes to such return requested by the Shareholder Representative. The Shareholder Representative and the Buyer Parties agree to consult and resolve in good faith any issue arising as a result of the review of such Pre-Closing or Straddle Period Tax Return and to mutually consent to the filing of such return as promptly as possible.

With respect to any Tax Claim relating to a Pre-Closing Period, the Shareholder Representative shall solely at its own cost and expense control all proceedings and may make all decisions taken in connection with such Tax Claim (including selection of counsel) and, without limiting the foregoing, may in its sole discretion pursue or forego any and all administrative appeals, proceedings, hearings and conferences with any taxing authority with respect thereto, and may, in its sole discretion, either pay the Tax claimed and xxx for a refund where applicable Law permits such refund suits or contest the Tax Claim in any permissible manner. In the event the Shareholder Representative is directly or indirectly conducting the defense against any such Tax Claim, it will keep the Buyer Parties reasonable informed of progress of the defense of such Tax Claim and, to the extent such Tax Claim could have a Material Adverse Effect on a Target Company in a period beginning after the Closing Date, shall not, without the prior written consent of the Buyer Parties (not to be unreasonably withheld, delayed or conditioned), settle or compromise any such Tax Claim or consent to the entry of any judgment in respect to such Tax Claim. The Shareholder Representative and the Buyer Parties shall jointly control and participate in all proceedings taken in connection with any Tax Claim relating to Taxes of a Target Company for a Straddle Period, and shall bear their own respective costs and expenses.

(j) In addition to the provisions set forth in Section 3.04(d) of this Agreement, until the expiration of a period of six months after the date of original issuance of the II-VI Shares (the “Distribution Compliance Period”), no Foreign Shareholder will sell or otherwise transfer the II-VI Shares, except (1) to II-VI or its Subsidiaries, (2) pursuant to an effective registration statement which has been declared effective under the Securities Act, (3) in an

offshore transaction in accordance with Rule 904 of Regulation S or (4) pursuant to any other available exemption from the registration requirements of the Securities Act.

Nothing in this paragraph is intended to amend or modify the provisions of Section 3.04(d).

Section 7.03 Restricted Securities: Rule 144. The Ordinary Shareholders understand that the II-VI Shares are characterized as “restricted securities” under the Securities Act inasmuch as they are being acquired in a transaction not involving a public offering and that under the Securities Act and applicable regulations thereunder such securities may be resold without registration under the Securities Act only in certain limited circumstances. In this connection, the Ordinary Shareholders represent that they are familiar with Rule 144 promulgated under the Commission, as presently in effect, and understand the resale limitations imposed thereby and by the Securities Act.

Section 7.04 Legends. It is understood that the certificates evidencing the II-VI Shares will bear the legends set forth below:

For U.S. Shareholders:

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR UNDER THE SECURITIES LAWS OF CERTAIN STATES. THESE SECURITIES ARE SUBJECT TO RESTRICTIONS ON TRANSFERABILITY AND RESALE AND MAY NOT BE TRANSFERRED OR RESOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE ACT AND IN EACH CASE ONLY IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS. THE ISSUER OF THESE SECURITIES MAY REQUIRE AN OPINION OF COUNSEL IN FORM AND SUBSTANCE REASONABLY SATISFACTORY TO THE ISSUER TO THE EFFECT THAT ANY PROPOSED TRANSFER OR RESALE IS IN COMPLIANCE WITH THE ACT AND ANY APPLICABLE STATE SECURITIES LAWS.

For Foreign Shareholders:

THE SECURITIES REPRESENTED HEREBY HAVE BEEN OFFERED IN AN OFFSHORE TRANSACTION TO A PERSON WHO IS NOT A U.S. PERSON (AS DEFINED HEREIN) PURSUANT TO REGULATION S UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”). NONE OF THE SECURITIES REPRESENTED HEREBY HAVE BEEN REGISTERED UNDER THE ACT, OR ANY U.S. STATE SECURITIES LAWS, AND, UNLESS SO REGISTERED, MAY NOT

BE OFFERED OR SOLD, DIRECTLY OR INDIRECTLY, IN THE UNITED STATES (AS DEFINED HEREIN) OR TO U.S. PERSONS EXCEPT IN ACCORDANCE WITH THE PROVISIONS OF REGULATION S UNDER THE ACT, PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT, OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE ACT AND IN EACH CASE ONLY IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS. IN ADDITION, HEDGING TRANSACTIONS INVOLVING THE SECURITIES MAY NOT BE CONDUCTED UNLESS IN COMPLIANCE WITH THE ACT. “UNITED STATES” AND “U.S. PERSON” ARE AS DEFINED BY REGULATION S PROMULGATED UNDER THE ACT.

The legends set forth above shall be removed by II-VI from any certificate evidencing II-VI Shares upon delivery to II-VI of an opinion by counsel, reasonably satisfactory to II-VI, that such security can be freely transferred in a public sale without such a registration statement being in effect and that such transfer will not jeopardize the exemption or exemptions from registration pursuant to which II-VI issued the II-VI Shares.
