At the Effective Time, the Merger shall have the effects set forth in the applicable provisions of the DGCL. The Surviving Corporation may, at any time after the Effective Time, take any action (including executing and delivering any document) in the name and on behalf of either the Company or Merger Sub in order to carry out and effectuate the transactions contemplated by this Agreement.

(ii) Certificate of Incorporation.

(iii) Bylaws. The bylaws of Surviving Corporation shall be amended and restated at and as of the Effective Time to read as did the bylaws of Merger Sub immediately prior to the Effective Time (except that the name of Surviving Corporation will remain unchanged).

(iv) Directors and Officers. The directors and officers of Merger Sub shall become the directors and officers of Surviving Corporation at and as of the Effective Time (retaining their respective positions and terms of office).

(A) each share of Series C-1 Preferred Stock that is issued and outstanding immediately prior to the Effective Time (other than shares of Series C-1 Preferred Stock that are Dissenting Shares or Parent-Owned Company Shares or are held in the treasury of the Company) shall be converted into and become the right to receive an amount in cash equal to the Series C-1 Per Share Liquidation Value;

(B) each share of Common Stock that is issued and outstanding immediately prior to the Effective Time (other than shares of Common Stock that are Dissenting Shares or Parent-Owned Company Shares or are held in the treasury of the Company) shall be converted into and become the right to receive (I) an amount in cash equal to the Common Share Closing Consideration and (II) a portion of the Additional Consideration to the extent earned and

payable following the Effective Time, as determined in accordance with the terms of Section 2(m); and

(C) each Parent-Owned Company Share and each Company Share held in the treasury of the Company shall be cancelled and retired and shall cease to exist and no consideration will be delivered in exchange therefor.

Notwithstanding the foregoing, in the event that the Aggregate Closing Merger Consideration shall be insufficient to fully fund the payments to Company’s Preferred Stock in accordance with the terms of Section 2(e)(v)(A), such payments shall be proportionately reduced in accordance with the terms of the Charter as it relates to the payments otherwise due to the Company’s Preferred Stock in connection with a Change of Control (as defined in the Charter).

(vii) Treatment of Company Options and Warrants.

(A) Company Options. Each Company Option that is outstanding and unvested prior to the Effective Time shall be fully accelerated immediately prior to the Effective Time. Each Company Option that is outstanding and held by a participant in the Santur Corporation 2011 Incentive Plan or in the Fixed Bonus Plan shall be terminated without any cash payment being made with respect thereto, provided that such Company Options held by participants in the Santur Corporation 2011 Incentive Plan shall not be so cancelled with respect to any such participant who validly executes and delivers an Incentive Plan Acknowledgment in the form attached hereto as Exhibit E-2. Each remaining Company Option (a “Participating Option”) that is outstanding and vested immediately prior to the Effective Time, including those whose vesting shall be accelerated immediately prior to the Effective Time, shall be terminated in accordance with the terms of the Company Stock Plans and shall represent only the right to receive, as promptly as practicable after the Effective Time and subject to the terms and conditions of this Agreement including the terms of Sections 2(i), 2(j), 2(m) and 8(d)(v), and the receipt of a customary letter of transmittal or similar document containing terms substantially similar to those included in the Equityholder Acknowledgements, and for each share of Common Stock issuable upon the exercise of such Company Option, an amount in cash (without interest) equal to the positive difference, if any, between (i) the Merger Consideration that would otherwise have been payable in respect of such share of Common Stock pursuant to Section 2(e)(v) and (ii) the exercise price of such Company Option, as set forth on Schedule 2(g). For the avoidance of doubt, (1) each Company Option held by a participant in the Santur Corporation 2011 Incentive Plan or the Fixed Bonus Plan that is outstanding immediately prior to the Effective Time shall be terminated at the Effective Time in accordance with the terms of the Santur Corporation 2011 Incentive Plan or the Fixed Bonus Plan, as applicable, and shall not represent the right to receive the consideration set forth in this Section, provided that such Company Options held by participants in the Santur Corporation 2011 Incentive Plan shall not be so cancelled with respect to any such participant who validly executes and delivers an Incentive

Plan Acknowledgment in the form attached hereto as Exhibit E-2, and (2) any Company Option with a per-share exercise price equal to or greater than the Merger Consideration that would otherwise have been payable in respect of a Company Share pursuant to Section 2(e)(v) (assuming that all contingencies with respect to payment of such consideration were satisfied) shall be cancelled without payment at the Effective Time.

(B) Company Warrants. Company Warrants that are outstanding immediately prior to the Effective Time shall be terminated and shall represent only the right, upon the surrender of the certificate or instrument representing such Company Warrant and receipt of an applicable Equityholder Acknowledgement, to receive, as promptly as practicable after the Effective Time and subject to the terms and conditions of this Agreement, including Sections 2(i), 2(j), 2(m) and 8(d)(v) hereof, for each Company Share issuable upon the exercise of such Company Warrant (after taking into account the conversion of any Convertible Preferred Stock issuable upon the exercise thereof), an amount in cash equal to the Merger Consideration that would otherwise have been payable in respect of such Company Share pursuant to Section 2(e)(v), as set forth on Schedule 2(g).

(C) At or prior to the Effective Time, the Company, the Company’s board of directors and the compensation committee of the Company’s board of directors shall adopt such resolutions and take such actions (including obtaining any required consents) as may be necessary to effectuate the provisions of this Section 2(e)(vii). The Company acknowledges that Parent shall not be required to make any payments to holders of Company Options or Company Warrants until such holders have executed an acknowledgment that (i) the amount being is the full amount to which such holders are entitled under their respective Company Option or Company Warrant, (ii) upon payment of such amount their Company Option or Company Warrant will be cancelled and all rights thereunder terminated, (iii) a portion of such amount will be deposited in the Escrow Fund and the Reserve Fund, (iv) the holder will be subject to the indemnification obligations set forth in this Agreement, (v) the Stockholder Representative is appointed to act on behalf of the holder in the manner contemplated by this Agreement, and (iv) the holder is granting a full release of the Parties and their respective Affiliates as to any further amounts owing under such Company Option or Company Warrant. The form of equityholder acknowledgment contemplated by this Section 2(e) (the “Equityholder Acknowledgment”) with respect to Company Warrants entitled to a payment pursuant to the terms hereof is attached hereto as Exhibit D-1, and the form of Equityholder Acknowledgement with respect to Company Warrants not entitled to payment pursuant to the terms hereof is attached hereto as Exhibit D-2.

(f) Dissenting Shares. Notwithstanding anything in this Agreement to the contrary, Company Shares which are issued and outstanding immediately prior to the Effective Time and which are held by holders of such Company Shares who have properly exercised appraisal rights with respect thereto in accordance with Section 262 of the DGCL or Chapter 13 of the California Corporation Code, as the case may be, shall not be convertible into the right to receive cash pursuant to Section 2(e)(v) and holders of such Dissenting Shares shall be entitled to receive payment of the fair value of such shares in accordance with the provisions of Section 262 of the DGCL or Chapter 13 of the California Corporation Code, as the case may be, unless and until such holders fail to perfect or effectively withdraw or otherwise lose their rights to demand payment under the DGCL or the California Corporation Code, as the case may be. The

board of directors of the Company has determined that for purposes of Chapter 13 of the California Corporations Code the fair market value of a share of Company Common Stock is $0.038285. If, after the Effective Time, any such holder fails to perfect or effectively withdraws or loses such right, such Dissenting Shares shall thereupon be treated as if they had been converted into and have become exchangeable for, at the Effective Time, the right to receive the applicable amounts payable pursuant to this Agreement, without any interest thereon. The Company shall give Parent prompt notice (and in no event more than two Business Days) of any demand received by the Company for appraisal of Company Shares or notice of exercise of a holder’s appraisal rights in accordance with the DGCL or the California Corporation Code, as the case may be. The Company agrees that, except with Parent’s written consent, it shall not voluntarily make any payment or offer to make any payment with respect to, or settle or offer to settle, any such demand for appraisal or exercise of appraisal rights. Notwithstanding anything to the contrary contained in this Section 2(f), if the Merger is rescinded or abandoned, then the right of any stockholder to be paid the fair value of such stockholder’s Dissenting Shares pursuant to Section 262 of the DGCL or Chapter 13 of the California Corporation Code, as the case may be, shall cease.

(g) Merger Consideration. The aggregate consideration to be paid in cash by Parent at Closing in connection with the Merger equals the Aggregate Closing Merger Consideration. A portion of the Aggregate Merger Consideration and a portion of the Santur Corporation 2011 Incentive Amount that, in the aggregate, equals the Escrow Fund shall be deposited with the Escrow Agent and disbursed as provided in Section 2(c) and Section 8, and a portion of the Aggregate Closing Merger Consideration and a portion of the Santur Corporation 2011 Incentive Amount that, in the aggregate, equals the Reserve Fund shall be deposited into an account designated by the Stockholders Representative to fund the Reserve Fund. The calculation of the Aggregate Closing Merger Consideration, the Common Share Closing Consideration, the Santur Corporation 2011 Incentive Amount, and each defined term referred to in any such definition, together with the amount payable to each Company Stockholder (other than with respect to any Dissenting Shares), each holder of Participating Options, each holder of Company Warrants and to each participant in the Santur Corporation 2011 Incentive Plan (including the allocations among each of the foregoing for the Escrow Fund and the Reserve Fund) and each participant in the Fixed Bonus Plan are set forth on Schedule 2(g) (the “Spreadsheet”). The Company shall deliver to Parent (i) a pro forma Spreadsheet prior to the execution of this Agreement based on the information known to the Company and reasonable assumptions as to the Closing Date and the activities of the Parties in connection therewith and (ii) a final Spreadsheet at least two Business Days prior to the Closing Date.

(h) Santur Corporation 2011 Incentive Plan and Fixed Bonus Plan. Parent shall pay, or cause to be paid, the Santur Corporation 2011 Incentive Amount in satisfaction of the amounts to be payable pursuant to the Santur Corporation 2011 Incentive Plan and Fixed Bonus Plan. The Company shall use its reasonable best efforts to obtain (i) acknowledgments from each of the participants in the Santur Corporation 2011 Incentive Plan as to (A) the amount to be received thereunder being the full amount to which such participant shall be entitled under such plan (including a portion of the Additional Consideration, if any, in the future), (B) the fact that a portion of such amount is to be deposited in the Escrow Fund and the Reserve Fund, (C) the fact that the participant will be subject to the indemnification obligations set forth in this Agreement, and (D) the participant’s agreement to appoint the Stockholder Representative to act

on behalf of the participant in the manner contemplated by this Agreement, and (ii) a full release of the Parties and their respective Affiliates as to any further amounts owing under such plan. The form of acknowledgment and release contemplated by this Section 2(h) with respect to the Santur Corporation 2011 Incentive Plan (x) for participants who are participating in the Santur Corporation 2011 Incentive Plan is set forth as Exhibit E-1 and (y) for participants who are waiving participation in the Santur Corporation 2011 Incentive Plan and instead receiving payment for their Company Options is set forth as Exhibit E-2 hereto (each, an “Incentive Plan Acknowledgment”). Pursuant to the terms of the Fixed Bonus Plan, each participant in such plan shall sign a customary release as a condition to the receipt of the related bonus, and the Company shall use its reasonable best efforts to obtain such releases.

(i) Procedure for Payment.

(i) At the Closing, Parent will deposit, or cause to be deposited with U.S. Bank, National Association (the “Exchange Agent”) in cash (the “Payment Fund”) an amount sufficient in the aggregate for the Exchange Agent to make full payment of the amounts due at Closing in accordance with Section 2(e)(v) (assuming compliance with the terms hereof by all holders of Company Shares) and Section 2(e)(vii) (assuming compliance with the terms hereof by all holders of Company Options and Company Warrants, including Section 2(e)(vii)(C)). As soon as practicable following the Closing, and in any event within five (5) Business Days thereafter, Parent will cause a letter of transmittal (with instructions for its use) in the form attached hereto as Exhibit F (a “Letter of Transmittal”) to be mailed to each record holder of outstanding Company Shares for the holder to use in surrendering the certificates that represented his, her, or its Company Shares against payment of the amount due such holder. Upon surrender of certificates by a holder representing his, her, or its Company Shares for cancellation to Parent or the Exchange Agent, together with a Letter of Transmittal, duly completed and validly executed in accordance with the instructions thereto, and such other documents as may reasonably be required by the Exchange Agent (including any required Internal Revenue Service Form W-9 or Form W-8), the holders of such certificates shall be entitled to receive in exchange therefor a certified check or wire transfer in the amount of U.S. dollars representing the applicable portion of the Merger Consideration that such holders have the right to receive at the Closing pursuant to Section 2(e)(v), and the certificates so surrendered shall forthwith be cancelled. Any Company Stockholder that surrenders certificates representing his, her, or its Company Shares for cancellation, together with a Letter of Transmittal, in accordance with the preceding sentence shall be entitled to be paid the applicable portion of the Merger Consideration that such holder has the right to receive at the Closing pursuant to Section 2(e)(v) at the Closing. No interest will accrue or be paid to the holder of any outstanding Company Shares.

(ii) The Exchange Agent shall hold the cash in the Payment Fund in trust and pay out such cash in accordance with this Section 2. Any interest produced by cash deposited into the Payment Fund shall be payable to the Surviving Corporation or Parent, as directed by Parent. The Surviving Corporation shall pay all charges and expenses, including those of the Exchange Agent, incurred in connection with the exchange of Company Shares for Merger Consideration.

(iii) Parent may cause the Exchange Agent to pay over to Surviving Corporation any portion of the Payment Fund remaining five (5) Business Days after the six-month anniversary of the Effective Time, and thereafter all former stockholders shall be entitled to look to Surviving Corporation (subject to abandoned property, escheat, and other similar laws) as general creditors thereof with respect to the cash upon surrender of their certificates.

(j) The Escrow Fund.

(i) An escrow fund (the “Escrow Fund”) in the amount of $6,000,000 shall be established in accordance with the terms of the Escrow Agreement and shall be funded in accordance with Section 2(c). The Escrow Fund shall be withheld by Parent and allocated among the Participating Holders and participants in the Santur Corporation 2011 Incentive Plan, on a pro rata basis. The pro rata amount Parent shall withhold from each Participating Holder and participant in the Santur Corporation 2011 Incentive Plan, as applicable, shall be based on the aggregate amount of Merger Consideration that each such Person is entitled to receive at the Closing (disregarding any Merger Consideration payable with respect to any Series C-1 Preferred Stock (which shall not be held in escrow, regardless of whether the holder thereof is a Participating Holder) and without taking into account any deductions from such amount pursuant to this Section 2(j) or Section 8(d)(v)) pursuant to Sections 2(e)(v), 2(e)(vii) and 2(h), as the case may be (such pro rata amount, the “Pro Rata Share”).

(ii) The remaining balance of the Escrow Fund not paid to Parent or subject to an outstanding Claim Notice shall be distributed in accordance with this Section 2(j) as soon as practicable but not later than three (3) Business Days after the expiration of the Escrow Indemnity Period. Such remaining balance of the Escrow Fund, less any amounts subject to pending indemnity claims unresolved as of such date, plus any interest on the Escrow Fund shall be distributed by the Escrow Agent to the Exchange Agent or the Surviving Corporation, as then applicable, for payment to the Participating Holders as provided in Section 2(e)(v), Section 2(e)(vii)(A), or Section 2(e)(vii)(B), as the case may be, and participants under the Santur Corporation 2011 Incentive Plan as provided in Section 2(h).

(iii) Parent, the Company, and the Participating Holders agree for all tax purposes that: (i) the right of the Participating Holders to the Escrow Fund shall be treated as deferred contingent purchase price eligible for installment sale treatment under Section 453 of the Code and any corresponding provision of foreign, state or local law, as appropriate; (ii) if and to the extent any amount of the Escrow Fund is actually distributed to the Participating Holders, interest may be imputed on such amount, as required by Section 483 or 1274 of the Code; (iii) Parent shall be treated as the owner of the Escrow Fund, and all interest and earnings earned from the investment and reinvestment of the Escrow Fund, or any portion thereof, shall be allocable to Parent pursuant to Section 468B(g) of the Code; (iv) Parent shall receive quarterly tax distributions from the Escrow Fund equal to the product of (A) the amount of taxable income allocated to Parent for the taxable period, multiplied by (B) 40%, and (v) in no event shall the total amount of the Escrow Fund and any interest and earnings earned thereon paid to the Participating Holders and participants under the Santur Corporation 2011 Incentive Plan under this Agreement exceed an amount to be designated by the Company prior to the Closing. Clause (v) of the preceding sentence is intended to ensure that the right of the Participating Holders to the Escrow Fund and any interest and earnings earned thereon is not treated as a contingent

payment without a stated maximum selling price under Section 453 of the Code and the Treasury Regulations promulgated thereunder.

(k) No Liability. None of Parent, Merger Sub, the Company or their respective officers, directors and stockholders or the Exchange Agent shall be liable to any Person in respect of any portion of the Merger Consideration delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. If any certificates representing Company Shares shall not have been surrendered prior to five (5) years after the Effective Time (or immediately prior to such earlier date on which any cash payable pursuant to Section 2(e)(v) would otherwise escheat to or become the property of any governmental entity), any such cash in respect of such Company Shares shall, to the extent permitted by applicable law, become the property of the Surviving Corporation, free and clear of all claims or interest of any Person previously entitled thereto.

(l) Lost, Stolen or Destroyed Certificates. If any certificate that prior to the Effective Time represented Company Shares shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such certificate to be lost, stolen or destroyed and, if required by Parent and the Surviving Corporation, a bond or an agreement to indemnify Parent and the Surviving Corporation against any claim that may be made against it with respect to such certificate, the Exchange Agent will deliver in exchange for such lost, stolen or destroyed certificate the applicable amounts payable pursuant to this Agreement with respect to the Company Shares formerly represented by such certificate.

(m) Earn Out.

(i) If Company Gross Profit during any of the four (4) calendar quarters of calendar year 2012 (each, a “Measurement Period”) exceeds $3,000,000, an amount equal to the product of (A) the positive difference between (I) the Company Gross Profit during such Measurement Period and (II) $3,000,000, multiplied by (B) 75%, shall be deemed to be “Additional Consideration,” provided that the aggregate amount of Additional Consideration, regardless of the level of Company Gross Profit during any or all Measurement Periods, shall not exceed $7,500,000. An aggregate amount equal to the total Additional Consideration, if any, shall be paid by Parent no later than ninety (90) days following the conclusion of the final Measurement Period to the Earn Out Participants, with such aggregate amount to be allocated among the Earn Out Participants in accordance with the amounts such Earn Out Participants would have received if such Additional Consideration was included as part of the Aggregate Closing Merger Consideration payable at the Closing, provided that such payment shall only be made to Earn Out Participants who have complied with the terms hereof such that they received payment for their Company Shares hereunder or the payment to which they were initially entitled under the Santur Corporation 2011 Incentive Plan. Parent shall act in good faith and not in a manner with a specific intent to reduce the payments under this Section 2(m); provided, however, that Parent shall be entitled to operate the Company’s business following the Closing in a manner consistent with the business judgment of Parent’s board of directors and management and the Company’s business will be subject to the same review and resource planning as Parent’s other business units following the Closing.

(ii) The determination of the Company Gross Profit and Additional Consideration, if any, for each Measurement Period shall be made by Parent, and written notice thereof together with a calculation of the Company Gross Profit and Additional Consideration, setting forth the components thereof in reasonable detail shall be delivered to the Stockholder Representative (a “Gross Profit Notice”) no later than forty-five (45) days following the completion of each Measurement Period. If the Stockholder Representative delivers written notice (a “Dispute Notice”) to Parent within thirty (30) days after any Gross Profit Notice is given in accordance with Section 2(m), stating that the Stockholder Representative objects to the amount of the Company Gross Profit and Additional Consideration reflected therein, specifying the basis for such objection in reasonable detail (including the specific items in dispute), and setting forth the Stockholder Representative’s proposed amount of such Company Gross Profit and Additional Consideration (including the proposed amounts of the disputed items), the Stockholder Representative and Parent will attempt to resolve and finally determine and agree upon such Company Gross Profit and Additional Consideration, as promptly as practicable. If the Stockholder Representative does not deliver a Dispute Notice to Parent within thirty (30) days after a Gross Profit Notice is given in accordance with Section 2(m) (or at such earlier time as the Stockholder Representative delivers written notice to Parent stating that the Stockholder Representative does not object to any items in such Gross Profit Notice), the Company Gross Profit and Additional Consideration specified in the Gross Profit Notice for such Measurement Period will be conclusively presumed to be true and correct in all respects and will be final and binding upon the parties. In connection with the review of any Gross Profit Notice, to the extent the Stockholder Representative does not possess all relevant information, the Stockholder Representative and its advisors will be permitted reasonable access (including electronic access to the extent available) to review the books, records and other relevant information of Parent and the Surviving Corporation relating to the Company’s business, operations, accounts and other financial information as it relates to the Company Gross Profit, and Parent shall (A) make reasonably available the individuals employed by Parent or the Surviving Corporation, as applicable, who are responsible for and knowledgeable about the information used in, and the preparation of, the financial statements upon which the Company Gross Profit and Additional Consideration are based and (B) use its commercially reasonable efforts to cause its independent accountants and other representatives to be made available, in each case, in order to assist the Stockholder Representative in the review of such Gross Profit Notice.

(iii) If the Stockholder Representative and Parent are unable to agree upon the Company Gross Profit and Additional Consideration for a Measurement Period within thirty (30) calendar days after a Dispute Notice is given in accordance with Section 2(m)(ii), the Stockholder Representative and Parent will jointly select an independent, internationally recognized accounting firm that has not provided material services to either Parent or the Company in the five (5) years preceding the date of this Agreement to resolve the disputed amount and make a determination of the applicable Company Gross Profit and Additional Consideration. The accounting firm shall address only the disputed items set forth in the Dispute Notice and may not assign a value greater than the greatest value claimed for such item by either party or smaller than the smallest value claimed for such item by either party. The accounting firm will (i) resolve the disputed items specified in the Dispute Notice and (ii) determine the Company Gross Profit and Additional Consideration, as modified only by the resolution of such items. The determination by the accounting firm so selected will be made within thirty (30) calendar days after such selection and will be final and binding upon the parties. The fees, costs

and expenses of (i) the accounting firm so selected and (ii) any attorney or auditor retained by either party for consultation as part of the dispute resolution process will be borne by the party (for the avoidance of doubt, by either the Company Indemnifying Parties or Parent) whose positions generally did not prevail in such determination, or if the accounting firm determines that neither party could be fairly found to be the prevailing party, then such fees, costs and expenses will be borne fifty percent (50%) by the Company Indemnifying Parties and fifty percent (50%) by Parent. In the event that fees, costs or expenses shall be allocated to the Company Indemnifying Parties pursuant to the foregoing, Parent shall be entitled to pay any such fees, costs and expenses and deduct a like amount from the Escrow Fund, without regard to the Basket Amount.

(n) Continuation of Vesting and Repurchase Rights. As to any Unvested Company Shares, the repurchase option, vesting schedule or other conditions applicable to such Unvested Company Shares shall be assigned to Parent and the consideration issuable upon conversion of such Unvested Company Shares in the Merger shall be retained by the Surviving Corporation or Parent and be subject to the same restrictions and vesting arrangements that were applicable to such Unvested Company Shares immediately prior to or at the Effective Time. The Company shall take all actions that may be necessary to ensure that, from and after the Effective Time, Parent (or its assignee) is entitled to exercise or otherwise enforce any such repurchase option, vesting schedule or other condition, such that upon termination of service or the end of any applicable performance or other vesting period, any portion of the consideration that remains unvested at such time shall be forfeited to the Surviving Corporation or Parent without compensation to such holder (other than payment of the lesser of the original purchase price of any Unvested Company Shares in respect of which consideration is being held by the Surviving Corporation or Parent or the fair market value as of the date of the forfeiture of such consideration). The consideration issuable upon conversion of Unvested Company Shares in the Merger will be paid promptly to the holders thereof on a quarterly basis with respect to the portion of such Unvested Company Shares that vest during the applicable quarterly period, provided that Parent shall be deemed to be in compliance with the foregoing requirement if it shall make the required payment to all holders of Unvested Company Shares on a single day during each applicable quarter, irrespective of the day of the quarter on which an individual’s Unvested Company Shares shall actually vest during the quarter.

(o) Adjustments. In the event of any stock split, reverse stock split, stock dividend (including any dividend or distribution of securities convertible into capital stock), reorganization, reclassification, combination, recapitalization or other like change with respect to the Company Shares occurring after the date hereof and prior to the Effective Time, all references in this Agreement to specified numbers of shares of any class or series affected thereby, and all calculations provided for that are based upon numbers of shares of any class or series affected thereby, shall be equitably adjusted to the extent necessary to provide the parties the same economic effect as contemplated by this Agreement prior to such stock split, reverse stock split, stock dividend, reorganization, reclassification, combination, recapitalization or other like change.

(p) Further Assurances. Each Party shall execute such further documents and instruments and take such further actions as may reasonably be requested by one or more of the others to consummate the Merger, to vest the Surviving Corporation with full title to all assets,

properties, rights, approvals, immunities and franchises of Merger Sub and the Company or to otherwise effect the purposes of this Agreement.

(q) Withholding Taxes. Notwithstanding any other provision in this Agreement, Parent (and any other Person that has any withholding obligation with respect to any payment made pursuant to this Agreement) shall be entitled to deduct and withhold from the payments to be made pursuant to this Agreement any Taxes required to be deducted and withheld with respect to the making of such payments under the Code or any other applicable provision of law. To the extent that amounts are so withheld pursuant to this Agreement, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to such Person in respect of which such deduction and withholding was made. Notwithstanding the foregoing, no withholding shall be required under the Code with respect to payments to Company Stockholders (in their capacity as Company Stockholders) that have not provided services to the Company, provided that such Company Stockholders provide properly completed Internal Revenue Service Forms W-9 or Forms W-8, as applicable. In addition, if Parent (or any other Person) determines that any withholding is required in respect of the payments to be made on the Closing Date to any Company Stockholders (in their capacity as Company Stockholders), Parent (or any other Person) shall notify the Company (with a copy to the Stockholder Representative), in writing, at least five (5) days prior to the Closing Date, of the amount that it intends to withhold and the legal basis for the requirement of such withholding.

The Financial Statements (including the notes thereto) have been prepared in accordance with GAAP throughout the periods covered thereby and present fairly, in all material respects, the financial condition of the Company as of such dates and the results of operations of the Company for such periods; provided, however, that the Most Recent Financial Statements are subject to normal year-end adjustments and lack footnotes and other presentation items.

Since the date of the Most Recent Balance Sheet and as of the date hereof, (i) there has not been any Material Adverse Change and (ii) the Company has not taken any action that would require Parent’s consent pursuant to Section 5(d) if taken after the date hereof.

(h) Undisclosed Liabilities. As of the date hereof, the Company does not have any liabilities that would be required to be disclosed on a balance sheet of the Company prepared in accordance with GAAP, except for (i) liabilities reflected or reserved for on the Most Recent Balance Sheet or disclosed in the notes thereto, (ii) liabilities that have arisen after the date of the Most Recent Balance Sheet in the Ordinary Course of Business or that will be Closing Costs, (iii) liabilities for future obligations provided by any Contract to which the Company is a party that has been made available to Parent and that is in effect as of the date hereof and that do not result from any breach of such Contract, and (iv) liabilities and obligations disclosed on Section 3(h) of the Disclosure Schedule.

(i) Legal Compliance; Permits. The Company has materially complied with all applicable laws (including rules, regulations, codes, plans, injunctions, judgments, orders, decrees and rulings thereunder) of federal, state, local, and non-U.S. governments (and all agencies thereof). The Company holds all permits, licenses and approvals from, and has made all filings with, all federal, state, local, and non-U.S. governments (and all agencies thereof) that are legally required to be held to conduct the business of the Company, including any permits, licenses and approvals necessary to use or occupy the Real Property, without any material violations of law (“Governmental Permits”), and all such Governmental Permits are valid and in full force and effect. The Company has never received any written notice or other written communication, or to the Knowledge of the Company, any oral notice or other oral notification, from any federal, state, local, and non-U.S. governments (and all agencies thereof) regarding (i) any actual or possible violation of law or any Governmental Permit or any failure to comply with any term or requirement of any Governmental Permit or (ii) any actual or possible revocation, withdrawal, suspension, cancellation, termination or modification of any Governmental Permit.

(j) Tax Matters.

(i) The Company has filed all Income Tax Returns and all other material Tax Returns that it was required to file before the date hereof. All such Tax Returns as so filed are true, correct and complete in all material respects. All material Taxes due and owing by the Company (whether or not shown on any Tax Return) have been paid. The Company is not currently the beneficiary of any extension of time within which to file any Tax Return. There are no Liens for Taxes (other than Taxes not yet due and payable) upon any of the assets of the Company. The Company has withheld and paid all Taxes required to have been withheld and paid in connection with amounts paid or owing to any employee, independent contractor, or

other third party. The Most Recent Balance Sheet reflects all liabilities for unpaid Taxes of the Company for periods (or portions of periods) through the date of the Most Recent Balance Sheet. The Company does not have any liability for unpaid Taxes accruing after the date of the Most Recent Balance Sheet except for Taxes arising in the Ordinary Course of Business subsequent to the such date.

(ii) There is no material dispute or claim concerning any Tax liability of the Company claimed or raised by any authority in writing. Since January 1, 2006, no written claim has ever been received from a jurisdiction in which Tax Returns have not been filed by the Company or Taxes have not been paid by the Company to the effect that the Company is or may be subject to taxation by such jurisdiction,

(iii) Except as set forth on Section 3(j)(iii) of the Disclosure Schedule, no material audit or other examination of any Income Tax Return of the Company is presently in progress, nor has the Company been notified in writing of any request for such an audit or other examination. The Company has delivered to Parent correct and complete copies of all U.S. federal and state Income Tax Returns, other material Tax Returns, examination reports, and statements of deficiencies assessed against, or agreed to by the Company for all open taxable years. The Company has not waived any statute of limitations in respect of Taxes or agreed to any extension of time with respect to a Tax assessment or deficiency.

(iv) There is no agreement, Contract, arrangement, or plan that has resulted or could reasonably be expected to result, separately or in the aggregate, in the payment of any “excess parachute payment” within the meaning of Code §280G that would not be deductible by the Company. For purposes of the foregoing sentence, the term “payment” shall include (without limitation) any payment, acceleration, forgiveness of indebtedness, vesting, distribution, increase in benefits or obligation to fund benefits. The Company is not a party to or bound by any tax allocation or sharing agreement other than any agreement entered into in the Ordinary Course of Business, the principal purpose of which is unrelated to Tax. The Company (A) has not been a member of an Affiliated Group filing a consolidated federal Income Tax Return; nor (B) has any liability for the Taxes of any Person (other than the Company) under Reg. §1.1502-6 (or any similar provision of state, local, or non-U.S. law), as a transferee or successor, by contract, or otherwise.

(v) With respect to each contract, plan or arrangement covering any employee or former employee of the Company that is a “nonqualified deferred compensation plan” (as defined for purposes of Section 409A(d)(1) of the Code), (1) such plan has been operated since January 1, 2005 in compliance with Section 409A of the Code and all applicable IRS guidance promulgated thereunder to the extent such plan is subject to Section 409A of the Code and so as to avoid any tax, interest or penalty thereunder; (2) the document or documents that evidence each such plan have conformed to the provisions of Section 409A of the Code and the final regulations under Section 409A of the Code since December 31, 2008; and (3) as to any such plan in existence prior to January 1, 2005 and not subject to Section 409A of the Code, has not been “materially modified” (within the meaning of IRS Notice 2005-1) at any time after October 3, 2004. No Company Option (whether currently outstanding or previously exercised) is, has been or would be, as applicable, subject to any tax, penalty or interest under Section 409A of the Code.

(vi) The Company has not engaged in a transaction that constitutes a “listed transaction” as such term is defined in Treasury Regulation Section 1.6011-4(b)(2).

(vii) The Company will not be required to include any item of income in, or exclude any item of deduction from, taxable income for any taxable period (or portion thereof) ending after the Closing Date as a result of any change in method of accounting under the Code for a taxable period ending on or prior to the Closing Date.

(viii) The Company has not been the “distributing corporation” or the “controlled corporation” (in each case, within the meaning of Section 355(a)(1) of the Code) with respect to a transaction described in Section 355 of the Code (i) within the three (3)-year period ending as of the date of this Agreement, or (ii) in a distribution that could otherwise constitute part of a “plan” or “series of related transactions” (within the meaning of Section 355(e) of the Code) that includes the transactions contemplated by this Agreement.

(ix) The Company will not be required to include in income, or exclude any item of deduction from, taxable income for any taxable period (or portion thereof) ending after the Closing Date as a result of any (i) a “closing agreement” described in Section 7121 of the Code (or any corresponding or similar provision of state, local, or foreign Tax law); (ii) intercompany transactions or any excess loss account described in Treasury Regulations under Section 1502 of the Code (or any corresponding or similar provision of state, local, or foreign Tax law); (iii) installment sale or open transaction disposition made on or prior to the Closing Date; or (iv) prepaid amount received on or prior to the Closing Date.

(x) The Company has not been a United States real property holding corporation within the meaning of Section 897(c)(2) of the Code during the applicable period specified in Section 897(c)(l)(A)(ii) of the Code.

(xi) No stockholder of the Company holds stock of the Company that are non-transferable and subject to a substantial risk of forfeiture within the meaning of Section 83 of the Code with respect to which a valid election under Section 83(b) of the Code has not been made, and no payment to any such stockholder of any portion of the consideration payable pursuant to this Agreement will result in compensation or other income to such stockholder with respect to which withholding of any Taxes is required.

(xii) Notwithstanding anything to the contrary in this Agreement, the Company makes no representations or warranties in respect of the existence, amount or usability of the tax attributes of the Company or any Subsidiary for taxable periods (or portions thereof) beginning after the Closing Date, including, without limitation, net operating losses, capital loss carryforwards, foreign tax credit carry forwards, research and development credits, asset bases and depreciation periods.

(k) Tangible Assets. The Company has good title to, or a valid leasehold interest in, all of its tangible assets and properties, free and clear of all Liens. Such assets are sufficient for the continued operation of the Company’s business. The machinery, equipment, and other tangible assets that the Company owns and leases are free from material defects and are in good operating condition and repair (subject to normal wear and tear). All leases of personal property to which the Company is a party are fully effective and afford the Company a valid leasehold possession of the personal property that is the subject of the lease. Section 3(k) of

the Disclosure Schedule sets forth a complete and accurate list of all personal property owned by the Company with an original purchase price of $3,000 or greater.

(l) Real Property.

(i) Section 3(l)(i) of the Disclosure Schedule sets forth the address of each parcel of real property that is owned by the Company. The Company has good and indefeasible title to all of such real property, free of all Liens except for those Liens set forth on Section 3(l)(i) of the Disclosure Schedule.

(ii) Section 3(l)(ii) of the Disclosure Schedule sets forth the address of each parcel of Leased Real Property, and a true and complete list of all Leases for each such Leased Real Property (including the date and name of the parties to such Lease). The Company has delivered to Parent a true and complete copy of each such Lease. Except as set forth in Section 3(l)(ii) of the Disclosure Schedule, with respect to each of the Leases:

(A) such Lease is legal, valid, binding, enforceable and in full force and effect;

(B) the Company’s possession and quiet enjoyment of the Leased Real Property under such Lease has not been disturbed and, to the Knowledge of the Company, there are no disputes with respect to such Lease;

(C) neither the Company nor, to the Knowledge of the Company, any other party to the Lease, is in breach of or default under such Lease in any material respect, and, to the Knowledge of the Company, no event has occurred or circumstance exists that, with the delivery of notice, the passage of time or both, would constitute such a breach or default under such Lease; and

(D) the Company has not subleased, licensed or otherwise granted any Person any right to use or occupy the Leased Real Property or any portion thereof.

(iii) The properties identified in Sections 3(l)(i) and 3(l)(ii) of the Disclosure Schedule (collectively, the “Real Property”) comprise all of the real property used in the business of the Company, and the Company is not a party to any agreement or option to purchase any real property or interest therein.

(iv) All buildings, structures, building systems and equipment, and all components thereof, included in the Real Property (the “Improvements”) are in good condition and repair and sufficient for the operation of the Company’s business. To the Company’s Knowledge, there are no structural deficiencies affecting any of the Improvements and there are no facts or conditions affecting any of the Improvements that would, individually or in the aggregate, interfere in any material respect with the use or occupancy of the Improvements or any portion thereof in the operation of the Company’s business as currently conducted thereon.

(v) There is no condemnation, expropriation or other proceeding in eminent domain, pending or threatened, affecting any parcel of Real Property or any portion thereof or interest therein.

(i) Insurance. The Company may obtain prepaid (or “tail”) directors’ and officers’ liability insurance policy covering each officer and director currently covered by the Company’s directors’ and officers’ liability insurance policy for acts or omissions occurring prior to the Effective Time with respect to any matter claimed against such Person by reason of him or her serving in such capacity on terms with respect to such coverage and amounts no less favorable in the aggregate than those of such policy in effect on the date of this Agreement, with coverage for no more than six (6) years following the Effective Time, provided that the full cost of all premiums associated with such policy (the “Tail Premium”) are paid in a lump sum by the Company prior to or at the Closing or shall be treated as a Closing Cost, in each case, the material terms of which including coverage and amount, are no less favorable in the aggregate to such directors and officers than the insurance coverage otherwise required under this Section 5(h)(i). Any insurance policies provided pursuant to this Section 5(h)(i) shall be from an insurance company with an A.M. Best Co. rating at least as high as the rating received by the Company’s current insurance provider.

(ii) Indemnification. Parent and Merger Sub agree to cause the Surviving Corporation to fulfill and honor all rights to indemnification, advancement of expenses and exculpation by the Company now existing in favor of each Person who is now, or has been at any time prior to the date hereof or who becomes prior to the Effective Time, an officer or director of the Company (each, a “Company Indemnified Party”) as provided in the Charter Documents of the Company, in each case as in effect on the date of this Agreement, or pursuant to any Company Contract set forth on Section 3(n)(T) of the Disclosure Schedule that is in effect on the date hereof, for a period of six (6) years from the Effective Time, and, in the event that any proceeding is pending or asserted or any claim made during such period, until the final disposition of such proceeding or claim. For six (6) years after the Effective Time, Parent shall cause the certificate of incorporation and by-laws of the Surviving Corporation to contain provisions no less favorable with respect to indemnification and limitation of liabilities of Indemnified Parties and advancement of expenses than are set forth as of the date of this Agreement in the Charter Documents of the Company; provided that the foregoing shall in no way be deemed to restrict the ability of Parent to cause the merger or dissolution of the Surviving Corporation at anytime following the Closing so long as it complies with its obligations pursuant to Section 5(h)(iv) below.

(iii) Third-Party Beneficiaries; Successors and Assigns. The obligations of Parent and the Surviving Corporation under this Section 5(h) shall survive the consummation of the Merger and shall not be terminated or modified in such a manner as to adversely affect any Company Indemnified Party to whom this Section 5(h) applies without the consent of such affected Company Indemnified Party (it being expressly agreed that the Company Indemnified Parties to whom this Section 5(h) applies shall be third party beneficiaries of this Section 5(h), each of whom may enforce the provisions of this Section 5(h)).

(iv) Continuing Obligation. In the event Parent, the Surviving Corporation or any of their respective successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity in such consolidation or merger; or (ii) transfers all or substantially all of its properties and assets to any Person, then, and in either such case, proper provision shall be made so that the successors and assigns of Parent or the Surviving Corporation, as the case may be, shall assume all of the obligations set forth in this Section 5(h). The agreements and covenants contained herein shall not be deemed to be exclusive of any other rights to which any Company Indemnified Party is entitled, whether pursuant to applicable law, Contract or otherwise. Nothing in this Agreement is intended to, shall be construed to or shall release, waive or impair any rights to directors’ and officers’ insurance claims under any policy that is or has been in existence with respect to the Company or its officers, directors and employees, it being understood and agreed that the indemnification provided for in this Section 5(h) is not prior to, or in substitution for, any such claims under any such policies.

(i) Employee Matters.

(i) Continuing Employees. Parent shall give each employee of the Company as of the Effective Time who continues employment with the Surviving Corporation or any of its Affiliates following the Effective Time (each, a “Continuing Employee” and, collectively, the “Continuing Employees”) full credit for prior service with the Company for purposes of (A) eligibility and vesting under any Parent Employee Plan, and (B) determination of benefit levels under any Parent Employee Plan or policy relating to vacation or severance, in each case under any Parent Employee Plan for which the Continuing Employee is otherwise eligible and in which the Continuing Employee is offered participation, but except where such credit would result in a duplication of benefits. In addition, Parent shall use commercially reasonable efforts to waive, or cause to be waived, subject in each case to the terms of the applicable plan and any required consent of the applicable insurance provider, any limitations on benefits relating to pre-existing conditions to the same extent such limitations are waived under any comparable plan of the Company and recognize for purposes of annual deductible and out-of-pocket limits under its medical and dental plans, deductible and out-of-pocket expenses paid by Continuing Employees in the calendar year in which the Effective Time occurs. For purposes of this Agreement, the term “Parent Employee Plan” shall mean any Parent employee benefit plan provided by Parent or its wholly owned operating subsidiary covering United States employees for which length of service is relevant (excluding any defined benefit plan, equity plan or phantom equity plan).

(ii) Post Effective Time. During the one (1) year period following the Effective Time, Parent shall, or Parent shall cause the Surviving Corporation and its Subsidiaries

to, provide to all Continuing Employees, to the extent they remain employed during such one (1) year period, compensation and benefits that are in the aggregate substantially comparable to either (A) the benefits and compensation provided by the Company to the Continuing Employees as in effect as of the date of this Agreement; or (B) the benefits and compensation provided to similarly situated Parent employees, provided that this provision shall not be deemed to be any guarantee of continued employment. Parent shall have discretion to select the specific benefits to be provided to Continuing Employees pursuant to this Section 5(i)(ii).

(iii) No Amendment. Nothing in this Section 5(i) shall (A) be treated as an amendment of, or undertaking to amend, any benefit plan; (B) prohibit Parent or any of its Subsidiaries, including the Surviving Corporation, from amending or terminating any employee benefit plan; (C) obligate Parent, the Company, the Surviving Corporation or any of their respective Affiliates to retain the employment or services of any particular Company employee or any other individual; or (D) confer any rights or benefits on any Person other than the Parties to this Agreement.

(iv) Terminated Employees. Prior to the Effective Time, the Company shall terminate all Terminated Employees and pay all of its contractual obligations in effect on the date hereof with respect to severance payments, accrued vacation payments or other obligations associated therewith. Any payments not required by applicable Law or by the Company’s contractual obligations in effect on the date hereof proposed to be made to any such Terminated Employees, shall only be made with Parent’s prior written consent. All such payments and accrued benefits and payments shall be fully reflected in the Company financial statements as of the Closing, provided that the calculation of Company Cash and the Closing Net Working Capital Amount shall be adjusted to eliminate the effects of the payments to or owing to any Terminated Employees in accordance with the terms of this Section 5(i)(iv).

(v) Retention Program. Parent will implement a retention plan for Continuing Employees providing for a grant of options to purchase an aggregate of 500,000 shares of Parent common stock, with the individuals participating in such program, the allocation among such individuals and the vesting terms thereof to be mutually agreed between the Chief Executive Officer of the Company and the Chief Executive Officer of Parent within 30 days following the Closing.

(j) FIRPTA Certificate. On the Closing Date, the Company shall deliver to Parent a properly executed statement in a form reasonably acceptable to Parent for purposes of satisfying Parent’s obligations under Treasury Regulations Section 1.1445-2(c)(3).

(k) State Takeover Statutes. The Company’s board of directors shall take commercially reasonable actions sufficient to render inapplicable to the Merger, the execution, delivery and performance of this Agreement and the transactions contemplated hereby and thereby, the provisions of Section 203 of Delaware Law applicable to a “business combination” (as defined in such Section 203 of DGCL).

(l) Preparation and Filing of Tax Returns.

(i) Parent (and its Subsidiaries and Affiliates) shall not amend or file any Tax Returns of the Company for any taxable period ending on or prior to the Closing Date without the prior written consent of the Stockholder’s Representative, which shall not be unreasonably withheld or delayed.

(ii) For the portion of the Closing Date after the time of Closing, other than transactions expressly contemplated hereby, Parent shall not cause the Surviving Corporation to take any action outside the Ordinary Course of Business.

(m) Termination of 401(k) Plan. The Company will adopt, or will cause to be adopted, all necessary corporate resolutions to terminate each 401(k) Plan sponsored or maintained by the Company, effective as of no later than one day prior to Closing (but such termination may be contingent upon the Closing). Immediately prior to such termination, the Company will make all necessary payments to fund the contributions: (i) necessary or required to maintain the tax-qualified status of the 401(k) Plan; (ii) for elective deferrals made pursuant to the 401(k) Plan for the period prior to termination; and (iii) for employer matching contributions (if any) for the period prior to termination. For this purpose, the term “401(k) Plan” means any plan intended to be qualified under Code Section 401(a) which includes a cash or deferred arrangement intended to qualify under Code Section 401(k). Before the Closing Date, the Company shall provide Parent with a copy of resolutions duly adopted by the Company’s board of directors so terminating any such 401(k) Plan.

(n) 280G Stockholder Approval. The Company shall use its reasonable best efforts to obtain the approval by such number of stockholders of the Company as is required by the terms of Section 280G(b)(5)(B) of the Code so as to render the parachute payment provisions of Section 280G of the Code inapplicable to any and all payments and/or benefits provided pursuant to contracts or arrangements that, in the absence of valid waivers of the right to receive such payments and/or benefits by the affected Persons, might otherwise result, separately or in the aggregate, in the payment of any amount and/or the provision of any benefit that would not be deductible by reason of Section 280G of the Code, with such stockholder approval to be obtained in a manner which satisfies all applicable requirements of such Section 280G(b)(5)(B) of the Code and the Treasury Regulations thereunder, including Q-7 of Section 1.280G-1 of such Treasury Regulations.

The Parent Indemnified Persons’ rights to indemnification under this Section 8 shall be subject to the following limitations: (i) in no event shall the aggregate amount to be paid to Parent under this Section 8 as a result of claims pursuant to Section 8(b) (other than as a result of claims pursuant to Section 8(b) resulting from fraud, willful breach or intentional misrepresentation and other than as a result of claims pursuant to clauses (iv) or (vi) of Section 8(b)) exceed the amount then held from time to time in the Escrow Fund and (ii) no Parent Indemnified Persons shall be

entitled to recover any Loss or Losses otherwise recoverable pursuant to this Section 8 as a result of claims pursuant to Section 8(b)(i) until the aggregate amount of all Losses by Parent Indemnified Persons for which the Parent Indemnified Persons are entitled to indemnification pursuant to Section 8(b)(i) exceeds $100,000 (the “Basket Amount”), and in which case the Parent Indemnified Persons shall be entitled to indemnification from the first dollar of such Losses, including the Basket Amount.

(d) Stockholder Representative.

(i) The Company hereby appoints, and by adopting and approving this Agreement and the Merger, or delivering an Equityholder Acknowledgement, Incentive Plan Acknowledgement or letter of transmittal, as applicable, the Participating Holders and participants in the Santur Corporation 2011 Incentive Plan (collectively the “Holders”) shall be deemed to appoint, Shareholder Representative Services LLC (the “Stockholder Representative”), with full and unqualified power to delegate to one or more Persons the authority granted to it hereunder, to act as each of their agent and attorney-in-fact, with full power of substitution, to take all actions permitted or required by this Agreement and the Escrow Agreement on their individual and collective behalf, and to take any other actions deemed necessary or appropriate by the Stockholder Representative in accordance with the terms of this Agreement and the Escrow Agreement. The Stockholder Representative shall be permitted to communicate with the Holders, including in electronic form.

(ii) The Stockholder Representative shall have no liability whatsoever to any existing or former stockholder of the Company or to any other Person arising out of the matters contemplated by this Agreement or the Escrow Agreement, except only to the extent of any Losses caused exclusively by the Stockholder Representative’s willful misconduct or bad faith. In any event, any such liability shall be limited to direct damages resulting from such conduct and in no event shall the Stockholder Representative be liable for special, incidental or consequential damages incurred or suffered by any Person. The Stockholder Representative shall incur no liability to any existing or former stockholder of the Company or any other Person with respect to any action taken or suffered by it in reliance upon any note, direction, instruction, consent, statement or other documents believed by it to be genuine and duly authorized. The Stockholder Representative may, in all questions arising under this Agreement or the Escrow Agreement, rely on the advice of counsel and for anything done, omitted or suffered in good faith by the Stockholder Representative based on such advice, the Stockholder Representative shall not be liable to any existing or former stockholder of the Company or any other Person.

(iii) In the event of the death or permanent disability of the Stockholder Representative, or his resignation as Stockholder Representative, a successor Stockholder Representative shall be elected by a majority vote of the holders of outstanding Company Shares immediately prior to the Effective Time, with each such stockholder (or his or her successors or assigns) to be given a vote equal to the number of votes represented by the Company Shares held by such stockholder immediately prior to the Effective Time, provided that if no Person receives a majority of votes, the Person receiving the most votes will be the new Stockholder Representative and provided further that the new Stockholder Representative shall promptly inform Parent of any such event.

(iv) The stockholders of the Company immediately prior to the Effective Time, jointly and severally, shall, by adopting and approving this Agreement and the Merger, be deemed to have agreed to indemnify the Stockholder Representative from and against any loss, liability or expense incurred by the Stockholder Representative in the performance of his duties under the terms of this Agreement and the Escrow Agreement, except to the extent that any loss, liability or expense is was found in a final, non-appealable judgment to have been caused exclusively by the Stockholder Representative’s willful misconduct or bad faith. If not paid directly to the Stockholder Representative by the stockholders of the Company, any such losses, liabilities or expenses may be recovered by the Stockholder Representative from (A) the funds in the Reserve Fund, and (ii) the amounts in the Escrow Fund otherwise distributable to the Holders pursuant to the terms hereof and the Escrow Agreement at the time of distribution in accordance with written instructions delivered by the Stockholder Representative to the Escrow Agent; provided that while this Section allows the Stockholder Representative to be paid from the Reserve Fund and the Escrow Fund, this does not relieve the Holders from their obligation to promptly pay such losses, liabilities and expenses as they are suffered or incurred, nor does it prevent the Stockholder Representative from seeking any remedies available to it at law or otherwise.

(v) In order to provide a fund to pay directly, or reimburse the Stockholder Representative for, any legal, accounting or other third-party expenses incurred by the Stockholder Representative in connection with any matter related to the transactions contemplated by this Agreement plus any additional costs and expenses of the Company incurred prior to the Effective Time in connection with this Agreement and the transactions contemplated hereby as provided in Section 9(l), $250,000 of the Merger Consideration shall be deposited by Parent upon the Closing of the Merger in a separate account (the “Reserve Fund”) to be designated by the Stockholder Representative to be administered and used by the Stockholder Representative in accordance with this Section 8(d). The Reserve Fund shall be withheld by Parent and allocated among the Holders in accordance with their respective Pro Rata Shares. The Reserve Fund shall be held by the Stockholder Representative as agent and for the benefit of the Holders in a segregated client account. The Stockholder Representative will hold these funds separate from its corporate funds, will not use these funds for its operating expenses or any other corporate purposes and will not voluntarily make these funds available to its creditors in the event of bankruptcy. The Holders shall not receive interest or other earnings on the Reserve Fund and they each irrevocably transfer and assign to the Stockholder Representative any ownership right that they may have in any interest that may accrue on funds held in the Reserve Fund. The Holders acknowledge that the Stockholder Representative is not providing any investment supervision, recommendations or advice. The Stockholder Representative shall have no responsibility or liability for any loss of principal of the Reserve Fund other than as a result of its gross negligence or willful misconduct. For tax purposes, the Reserve Fund shall be treated as having been received and voluntarily set aside by the Holders at the time of Closing. The parties agree that the Stockholder Representative is not acting as a withholding agent or in any similar capacity in connection with the Reserve Fund. Upon the conclusion of the Stockholder Representative’s services under this Agreement and the Escrow Agreement, any remaining balance of the Reserve Fund that (a) was deposited into the Reserve Fund from the Merger Consideration on behalf of Participating Holders shall be disbursed to Parent or the Exchange Agent and (b) was deposited into the Reserve Fund from the Merger Consideration on behalf of

Santur Corporation 2011 Incentive Amount shall be disbursed to the Exchange Agent or Parent for payment to the individual participants.

(e) Notice of Claim. If Parent believes that it or any Parent Indemnified Person has suffered or incurred any Loss, it shall notify the Escrow Agent and the Stockholder Representative promptly in writing, and in any event within the applicable time period specified in Section 8(a), describing such Loss, all with reasonable particularity, indicating the amount (estimated in good faith, if necessary) of the Loss that has been or may be sustained by Parent and containing a reference to the provision of this Agreement in respect of which such Loss shall have occurred (a “Claim Notice”). If any legal action is instituted by a third party with respect to which Parent intend to claim indemnity under this Section 8, Parent shall promptly give written notice thereof to notify the Escrow Agent and the Stockholder Representative of such legal action. In any event, a failure or delay in notifying the Escrow Agent and the Stockholder Representative shall not affect Parent’s right to indemnity, except only to the extent such failure or delay materially and adversely prejudices the ability to defend against any legal action. Following the delivery of each such Claim Notice, the Stockholder Representative and its representatives and agents shall be given all such access (including electronic access, to the extent available) as they may reasonably require to the books and records of the Surviving Corporation and access to such personnel or representatives of the Surviving Corporation and Parent, including but not limited to the individuals responsible for the matters that are subject of such Claim Notice, as they may reasonably require for the purposes of resolving any disputes or responding to any matters or inquiries raised in the Claim Notice.

(f) Defense of Third Party Claims. Parent shall have the right to conduct and control, through counsel of its own choosing, any third party legal action or other claim, and any associated costs and expenses shall be included in the Losses for which the Parent Indemnified Persons may seek indemnification hereunder, but the Stockholder Representative may, at its election, participate in the defense thereof at the sole cost and expense of the Company Indemnifying Parties; provided, however, that if Parent shall fail to promptly assume and thereafter diligently prosecute the defense of any such legal action or other claim, then the Stockholder Representative may assume the defense thereof, through counsel of its own choosing. Parent may settle any claim or legal action the defense of which it is entitled to control hereunder, but to the extent such settlement would result in Losses for which the Company Indemnifying Parties are liable, only with the prior written consent of the Stockholder Representative, such consent not to be unreasonably withheld or delayed.

(g) Determination of Losses. Notwithstanding any provision in this Agreement to the contrary, all Losses for which Parent Indemnified Persons would otherwise be entitled to indemnification under this Section 8 shall be reduced by the amount of insurance proceeds, indemnification payments and other third-party recoveries to which the Parent Indemnified Persons actually receive in respect of any Losses incurred by the Parent Indemnified Persons, net of the cost to Parent Indemnified Persons to obtain such proceeds, payments or recourses. In the event the Parent Indemnified Persons are entitled to any insurance proceeds, indemnity payments or any third-party recoveries in respect of any Losses for which the Parent Indemnified Persons are entitled to indemnification pursuant to this Section 8, Parent shall use commercially reasonable efforts to obtain, receive or realize such proceeds, payments or recoveries. In the event that any such insurance proceeds, indemnity payments or other third-

party recoveries are realized by Parent subsequent to receipt by Parent of any indemnification payment hereunder in respect of the claims to which such insurance proceeds, indemnity payments or other third-party recoveries relate, appropriate refunds shall be made promptly by Parent of all or the relevant portion of such indemnification payment. As to Company Stockholders, all indemnification payments under this Section 8 shall be deemed adjustments to the Merger Consideration otherwise payable to such Company Stockholders.

(h) Exclusive Remedy. The Parties acknowledge and agree that the indemnification provisions in this Section 8 shall be the exclusive remedy of Parent with respect to the transactions contemplated by this Agreement, except (i) for the ability to apply to any court of competent jurisdiction for specific performance or injunctive relief and (ii) in the event of fraud, willful breach or intentional misrepresentation.

(i) Recoupment. In connection with claims pursuant to Section 8(b) of this Agreement, any and all Losses recoverable by Parent under this Section 8, together with all costs and expenses reasonably incurred in defending any third party legal action or any other claim that is the subject of a right to indemnity under this Section 8, including the amount of any settlement or of any judgment, shall be paid exclusively and solely out of the Escrow Fund and shall be without any further recourse to any other Person, provided that claims pursuant to Section 8(b) of this Agreement resulting from fraud, willful breach or intentional misrepresentation and claims pursuant to clauses (iv) or (vi) of Section 8(b) shall not be so limited. In the case of any claim for indemnification made pursuant to clauses (iv) or (vi) of Section 8(b), and except in the case of fraud, willful breach or intentional misrepresentation, each Company Indemnifying Party shall be liable (severally and not jointly) for such holder’s Pro Rata Share of the amount of any Losses resulting therefrom up to the aggregate portion of the Merger Consideration received by such Company Indemnifying Party pursuant to this Agreement. Claims arising out of fraud, willful breach or intentional misrepresentation shall not be capped under this Agreement.

(j) Financial Statement Reserves. Notwithstanding any provision in this Agreement to the contrary and except as contemplated by the indemnity items identified on Schedule 8(b), Parent shall not be entitled to indemnification for any Losses in respect of any liability or obligation to the extent such liability or obligation is specifically identified and accrued or reserved for on the Most Recent Financial Statements and reflected in the calculation of the Closing Net Working Capital Amount.

(k) Mitigation of Damages. Parent shall use commercially reasonable efforts to mitigate any Losses for which it is entitled to indemnification pursuant to this Section 8. For the avoidance of doubt such commercially reasonable efforts will include prior consultation with the Stockholder Representative for any Losses related to the matters identified in Section 8(b)(iii) or listed as 3 and 4 on Schedule 8(b). The Stockholders Representative shall have the right, but not the obligation, and shall be afforded the opportunity by the Parent to the extent reasonably possible, to take all available steps to minimize Losses for which the Parent is entitled to indemnification before such Losses actually are incurred by the Parent.

(l) Release of Escrow. The Escrow Fund shall be held and invested by the Escrow Agent in accordance with the terms of the Escrow Agreement. Each of Parent and the

Stockholders Representative shall from time to time submit joint written instructions to the Escrow Agent instructing the Escrow Agent to distribute the Escrow Fund in accordance with this Agreement and the Escrow Agreement.

ARTICLE IX

(a) Press Releases and Public Announcements. No Party shall issue any press release or make any public announcement relating to the subject matter of this Agreement without the prior written approval of the other Parties; provided, however, that any Party may make any public disclosure it believes in good faith is required by applicable law or any listing or trading agreement concerning its publicly traded securities, if any (in which case the disclosing Party will use its commercially reasonable efforts to advise the other Party prior to making the disclosure). Notwithstanding anything herein to the contrary, following the later of Closing or the time at which Parent shall publicly announce the consummation of the Merger (if ever), the Stockholder Representative shall be permitted to publicly announce that it has been engaged to serve as the Stockholder Representative in connection with the Merger as long as such announcement does not disclose any of the other terms of the Merger or the other transactions contemplated herein.

(h) Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware without giving effect to any choice or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Delaware.

(i) Consent to Jurisdiction. In any action or proceeding between any of the Parties arising out of or relating to this Agreement or any of the transactions contemplated by this Agreement, each of the Parties hereto: (i) irrevocably and unconditionally consents and submits, for itself and its property, to the exclusive jurisdiction and venue of the Court of Chancery of the State of Delaware (or, in the case of any claim as to which the federal courts have exclusive subject matter jurisdiction, the Federal court of the United States of America, sitting in Delaware); (ii) agrees that all claims in respect of such action or proceeding must be commenced, and may be heard and determined, exclusively in the Court of Chancery of the State of Delaware (or, if applicable, such Federal court); (iii) waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any such action or proceeding in the Court of Chancery of the State of Delaware (and, if applicable, such Federal court); and (iv) waives, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding in the Court of Chancery of the State of Delaware (or, if applicable, such Federal court). Each of the Parties hereto agrees that a final judgment in any such action or proceeding may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Each Party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 9(g).

(j) Amendments and Waivers. The Parties may mutually amend any provision of this Agreement at any time prior to the Effective Time; provided, however, that any amendment effected subsequent to stockholder approval will be subject to the restrictions contained in the DGCL. No amendment of any provision of this Agreement shall be valid unless the same shall be in writing and signed by all of the Parties. No waiver by any Party of any provision of this Agreement or any default, misrepresentation, or breach of warranty or covenant hereunder, whether intentional or not, shall be valid unless the same shall be in writing and signed by the Party making such waiver nor shall such waiver be deemed to extend to any prior or subsequent default, misrepresentation, or breach of warranty or covenant hereunder or affect in any way any rights arising by virtue of any prior or subsequent such default, misrepresentation, or breach of warranty or covenant.

(k) Severability. Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of

the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction.

(l) Expenses. Subject to the last sentence of this Section 9(l), each of the Parties will bear its own costs, fees and expenses (including legal fees and expenses) (collectively, “Expenses”) incurred in connection with this Agreement and the transactions contemplated hereby. In the case of the Company, the Closing Costs shall be paid in the manner specified in Section 2(c) at the Closing. In no event will any Party be liable (before or after the Closing) for any Expenses of the Company Stockholders relating to the transactions contemplated by this Agreement, provided that notwithstanding the foregoing, any such Expenses shall be deemed to be Closing Costs to the extent any Party hereto is liable therefor.

(m) Specific Performance. The Parties hereto agree that irreparable damage would occur if any provision of this Agreement requiring performance by a Party were not performed in accordance with the terms hereof or were otherwise breached, and that money damages or other legal remedies would not be an adequate remedy for such damages. It is accordingly agreed that the Parties shall be entitled to an injunction or injunctions to prevent breaches or threatened breaches of this Agreement or to enforce specifically the performance of the terms and provisions hereof. Each of the Parties hereto agrees not to raise any objections to the availability of the remedy of specific performance to prevent breaches of this Agreement or to enforce specifically the performance of the terms and provisions hereof.

(n) Waiver of Jury Trial.
