Subject to the terms and conditions of this Section 7.1, a portion of the Escrowed Stock Payment in the amount of Xxx Xxxxxxx Xxxxx Xxxxxxxx xxx 00/000 Xxxxxx Xxxxxx Dollars (USD$150,000) (the “Initial Payment”) shall be released from escrow and applied to the outstanding principal amount of the Stock Purchase Note not later than thirty (30) days following the Closing Date; provided, however that in the event that Kingstone Semiconductor fails to provide Buyer with evidence reasonably satisfactory to Buyer that the SAFE registration certificate of Kingstone Semiconductor has been updated pursuant to Section 7.8 below within ninety (90) days of Closing, the Company shall be obligated to repay to Buyer the full amount of the Initial Payment promptly following Buyer’s written request therefor. In addition, subject to the terms and conditions of this Section 7.1 a portion of the Escrowed Stock Payment in the amount of One Million Four Hundred Fifty Thousand and 00/100 United States Dollars (USD$1,450,000) shall be released from escrow and applied to the outstanding principal amount of the Stock Purchase Note promptly following Buyer’s receipt of evidence reasonably satisfactory to Buyer that the SAFE registration certificate of Kingstone Semiconductor has been updated pursuant to Section 7.8 below. Thereafter, the Company shall deliver to Buyer at the beginning of each month, an invoice for the amount actually spent in the immediately prior month. Subject to Sections 7.1(c) and 7.1(d) below, beginning with the invoice delivered for month in which the aggregate amount spent in all months exceeds USD$800,000, Buyer shall release from escrow each month a portion of the Escrowed Stock Payment equal to the amount actually spent by Kingstone Semiconductor for the immediately prior month. The funds released from escrow pursuant to this Section 7.1(a) shall be released to the Company and applied to the principal amount of the Stock Purchase Note from time to time. Such payments of principal on the Stock Purchase Note shall be contributed as a capital contribution to Kingstone Semiconductor and used by it to develop an ion implant machine and process for the solar market (the “Solar Tool”) in accordance with the Development Program attached hereto as Exhibit C (the “Development Program”). The delivery to the Company of the Stock Purchase Note and the Head-Start Payment shall be consideration for the Issued Stock received by Buyer upon Closing.

(b) On the Closing Date, in addition to the Escrowed Stock Payment, Buyer shall place into escrow Four Million and 00/100 United States Dollars (USD$4,000,000) (the “Solar Tool Funds”). The Solar Tool Funds shall be released from escrow by Buyer and delivered to the Company in the form of a loan (the “Solar Tool Loan”), to be evidenced by a promissory note and other documents in form and substance reasonably acceptable to Buyer and the Company (as indicated by the affirmative vote of at least four Company directors including the Kingstone Representative), which promissory note will be executed and delivered by the Company on or before the date that Buyer provides any funding pursuant to such loan. Subject to Sections 7.1(c) and 7.1(d) below, on the first day of each month during the period covered by the Development Program following the completion of all payments required under Section 7.1(a), Seller shall deliver to Buyer a request for release from escrow of a portion of the Solar Tool Funds as an advance to be delivered to the Company or its designated Subsidiary as part of the loan required to be provided by Buyer hereunder, the amount of which shall be determined by, and used to make payment against, a draw request issued by the Company for the amount actually to be spent under the Development Program in the immediately prior month, and Buyer shall release such amount from escrow promptly after receipt of such draw request. Upon the successful development by the Company or its Subsidiaries of the Beta Solar Tool as described in Section 7.2 below, the outstanding principal balance of the Solar Tool Loan shall be applied in complete satisfaction of the purchase price of two Beta Solar Tools to be purchased by Buyer from the Company. Buyer and the Company will negotiate in good faith to enter into and execute such documents or instruments as are necessary to document and evidence the Solar Tool Loan required under this Section 7.1(b) and the purchase of such Beta Solar Tools.

(c) On the Closing Date, Buyer shall deposit the Escrowed Stock Payment and the Solar Tool Funds into an escrow account (the “Non-Indemnity Escrow Account”) to be opened and maintained with the Escrow Agent. Payments of the Escrowed Stock Payment and the Solar Tool Funds shall be released from the Non-Indemnity Escrow Account pursuant to an escrow agreement (the “Non-Indemnity Escrow Agreement”) in the form attached hereto as Exhibit F. The Non-Indemnity Escrow Agreement shall provide for releases of payments from the Non-Indemnity Escrow Account upon delivery of written instructions to the Escrow Agent executed by both Buyer and the Company. Such written instructions shall be delivered by Buyer and the Company promptly upon satisfaction of the applicable conditions for release of any portion of the Escrowed Stock Payment or the Solar Tool Funds set forth in Sections 7.1(a) and 7.1(b) above, respectively. In the event Buyer exercises its rights pursuant to Section 7.1(d) below following a Purchase and Loan Termination Event, Buyer shall have no further obligation to release any funds from the Non-Indemnity Escrow Account and Buyer shall have the right to have all funds remaining in the Non-Indemnity Escrow Account returned to Buyer immediately upon delivery of written notice to the Escrow Agent. In the event Buyer exercises its rights pursuant to Section 7.1(d) below, the Company shall promptly deliver to the Escrow Agent such written instructions as are required to facilitate the return of funds to Buyer pursuant to this Section 7.1(c).

(d) At its option, Buyer may, by written notice to the Company, terminate its obligation to release funds from the Non-Indemnity Escrow Account under this Section 7.1 in the event that, at any time during the Development Program, (i) actual expenditures for achieving any Phase in the development of the Solar Tool exceed budgeted costs of such Phase under the Development Program by more than 25%, or (ii) the actual time required for achieving any Phase in the development of the Solar Tool exceeds the scheduled time for such Phase under the Development Program by more than 60 days (a “Purchase and Loan Termination Event”). Notwithstanding the foregoing, Buyer’s obligation to release funds from the Non-Indemnity Escrow Account hereunder shall resume if the Company and the Key Developers demonstrate to Buyer’s reasonable satisfaction that, notwithstanding any Purchase and Loan Termination Event which has occurred, the development of the Solar Tool can be successfully completed at a total cost and on a schedule acceptable to Buyer.

(e) Notwithstanding any other provision of this Agreement or the Amended and Restated Head-Start Agreement, if for any reason the Closing does not occur by the Drop Dead Date, the Company or its specified Affiliate shall have the right for a period of 180 days after the Drop Dead Date (and prior to the expiration of the Company’s rights under this Section 7.1(e) Buyer shall not sell, assign or otherwise transfer the Sale and Service Rights other than to an Affiliate of Buyer, it being understood and agreed that such a transfer to an Affiliate of Buyer is only permissible if such Affiliate transferee is subject to and bound by the provisions of this Agreement and the Amended and Restated Head Start Agreement relating to the Sale and Service Rights), to exercise by written notice to Buyer the option to terminate Buyer’s the Sale and Service Rights and any and all rights and privileges associated therewith, by payment to Buyer of a break-up amount equal to all of the payments previously provided by Buyer to the Company, excluding travel and logistic expenses associated with collaboration with Buyer (the “Break-Up Option”). In the event that the Company or its specified affiliate exercises the Break-Up Option, all rights of Buyer relating to the Solar Tool and any future Solar Tool shall immediately and irrevocably cease. Furthermore, Buyer shall semiannually disclose to the Company or its specified Affiliate any solar ion implanter design used by Buyer for the ensuing five (5) years, as well as such related information as the Company or its specified Affiliate shall request, so that the Company or its specified affiliate can verify that no confidential information or patents, trade secrets or other intellectual property of the Company or the Key Developers has been or is being used therein.

(f) For the avoidance of doubt, and notwithstanding anything to the contrary in this Agreement or the Head-Start Agreement, upon the Closing, the Head-Start Agreement shall be terminated and superseded in its entirety by the Amended and Restated Head-Start Agreement. Prior to the Closing the Head-Start Agreement shall remain in full force and effect and upon the termination of this Agreement, except as modified by Section 7.1(d) above, the Head-Start Agreement shall continue in full force and effect and shall govern the respective rights and obligations of Buyer, the Company, Seller and Shareholders. For the avoidance of doubt, the parties hereto hereby confirm and agree that the Head-Start Agreement requires Buyer to make payment to the Company of up to USD$2,000,000 subject to the terms thereof even if the Closing does not occur, except in the limited circumstances set forth in Section 2.3 of the Head-Start Agreement.

The certificates evidencing the shares of Buyer Stock comprising the Stock Payment shall bear legends identifying the applicable restrictions on transfer of such Buyer Stock.

7.4 Right of First Refusal and Standstill Agreement. Buyer, Seller and each Shareholder shall enter into an agreement (the “Right of First Refusal and Standstill Agreement”) in the form attached hereto as Exhibit G, pursuant to which (i) Seller and each such Shareholder shall agree not to sell any of its, his or her equity interests in the Company or any Subsidiary thereof prior to the date of the first commercial sale of the Solar Tool; provided, however, that such restriction shall expire in any event not later than two (2) years following the Closing Date; (ii) Seller and each such Shareholder shall grant Buyer a right of first refusal to purchase any equity interests in the Company proposed to be sold by Seller or such Shareholder after the Closing Date; and (iii) Buyer shall grant to Seller and/or the Shareholders a right of first refusal to purchase the Sale and Service Rights in the event Buyer proposes to sell such Sale and Service Rights after the Closing Date; provided, however that such right of first refusal relating to the Sale and Service Rights shall apply only to the sale or transfer of the Sale and Service Rights as an individual asset, and shall not apply to any sale or transfer of the Sale and Service Rights as part of the sale of all or substantially all of the assets of Buyer or a subsidiary of Buyer that comprises a substantial portion of the Buyer’s assets.

7.5 Management of the Company and Kingstone Semiconductor. From and after the Closing Date, the boards of directors of each of the Company and Kingstone Semiconductor (each a “Board” and together the “Boards”) shall consist of five directors. Each Board shall have three directors appointed by Buyer (the “Buyer Directors”) and two directors appointed by the Shareholders (the “Kingstone Representatives”). One of the Buyer Directors designated by Buyer shall be appointed as the Chairman of each of the Boards. Decisions made by each Board shall be made by a majority of the members of such Board; provided, however, that the following actions shall require the approval of four members of such Board, including one Kingstone Representative:

(b) Indemnification Procedures.

(i) A party seeking indemnification pursuant to this Section 8.2 (an “Indemnified Party”) on the basis of a claim asserted by a third party shall give prompt written notice to the party from whom such indemnification is sought (the “Indemnifying Party”) of the assertion of such claim, or the commencement of any action, suit or proceeding brought by a third party, in respect of which indemnity may be sought hereunder and will give the Indemnifying Party such information with respect thereto as the Indemnifying Party may reasonably request, but failure to give such notice shall not relieve the Indemnifying Party of any liability hereunder (except to the extent that the Indemnifying Party has suffered actual prejudice thereby). The Indemnifying Party shall have the right (but not the obligation), exercisable by written notice to the Indemnified Party within fifteen (15) days of receipt of notice from the Indemnified Party of the commencement of or assertion of any claim or action, suit or proceeding by a third party (other than a party or an Affiliate of any party hereto) in respect of which indemnity may be sought hereunder (a “Third Party Claim”), to assume the defense and control the settlement of such Third Party Claim which involves (and continues to involve) solely monetary damages; provided that: (a) the Indemnifying Party expressly agrees in such notice that, as between the Indemnifying Party and the Indemnified Party, the Indemnifying Party shall be solely obligated to satisfy in full and discharge any adverse money judgment or settlement resulting from the Third Party Claim (subject to the limitations provided in this Agreement); (b) the defense of such Third Party Claim by the Indemnifying Party will not, in the reasonable judgment of the Indemnified Party, have any continuing material adverse effect on the Indemnified Party’s business; (c) the Indemnifying Party makes adequate provision to provide reasonable assurances to the Indemnified Party of the ability of the Indemnifying Party to satisfy the full amount of any adverse monetary judgment that may result; (d) such Third Party Claim could not result in criminal liability of, or equitable remedies against, the Indemnified Party; and (e) the Indemnified Party does not reasonably believe that the interests of the Indemnifying Party and the Indemnified Party with respect to such Third Party Claim are in conflict with one another, and as a result, the Indemnifying Party could not adequately represent the interests of the Indemnified Party in such claim (the conditions set forth in clauses (a), (b), (c), (d), and (e) are collectively referred to as the “Litigation Conditions”).

(ii) Within fifteen (15) days after the Indemnifying Party has given written notice to the Indemnified Party of its intended exercise of its right to defend and control the right to settle a Third Party Claim, the Indemnified Party shall give written notice to the Indemnifying Party of any objection thereto based upon the Litigation Conditions. If the Indemnified Party so objects, the Indemnified Party shall continue to defend the Third Party Claim until such time as such objection is withdrawn. If no such notice of objection is given, or if any such objection is withdrawn, the Indemnifying Party shall be entitled to assume and conduct such defense, with counsel selected by the Indemnifying Party and reasonably acceptable to the Indemnified Party, until such time as the Indemnified Party shall give notice that any of the Litigation Conditions, in its reasonable judgment, are no longer satisfied. If the Indemnified Party is defending the claim after it has made an objection based upon the Litigation Conditions, the Indemnifying Party shall thereafter remain obligated to pay the amount found to be owing to or agreed to in a settlement made pursuant to Section 8.2(b)(iv) with the third party with respect to such Third Party Claim, and to pay (subject to the limitations provided in this Agreement) the costs (including attorneys’ fees and expenses) incurred by the Indemnified Party defending such Third Party Claim. The Indemnified Party shall defend any Third Party Claim with counsel selected by it and reasonably acceptable to the Indemnifying Party. If the Indemnified Party is defending the Third Party Claim for any reason pursuant to this Section 8.2(b), Indemnifying Party shall still be obligated with respect to the costs and expenses of any such defense (subject to the limitations provided in this Agreement).

(iii) The Indemnifying Party or the Indemnified Party, as the case may be, shall have the right to participate in (but not control), at its own expense, the defense of any Third Party Claim, which the other is defending as provided in this Agreement.

(iv) The Indemnifying Party, if it shall have assumed the defense of any Third Party Claim as provided in this Agreement, shall not consent to a settlement of, or the entry of any judgment arising from, any such Third Party Claim without the prior written consent of the Indemnified Party (which consent shall not be unreasonably withheld or delayed). The Indemnifying Party shall not, without the prior written consent of the Indemnified Party, enter into any compromise or settlement, which commits the Indemnified Party to take, or to forbear to take, any action, or which does not provide for a complete release by such third party of the Indemnified Party or which contains any admission or statement suggesting any wrongdoing on behalf of the Indemnified Party. The Indemnified Party shall have the sole and exclusive right to settle any Third Party Claim, on such terms and conditions as it deems reasonably appropriate, to the extent such Third Party Claim involves equitable or other non-monetary relief and shall have the right to settle any Third Party Claim involving monetary damages without the written consent of the Indemnifying Party if the Indemnifying Party fails to assume and maintain the defense of such claim pursuant to this Section 8.2(b).

(v) Whether or not the Indemnifying Party chooses to defend or prosecute any Third Party Claim, all the parties hereto shall cooperate in the defense or prosecution thereof and shall furnish such records, information and testimony, and attend such conferences, discovery proceedings, hearings, trials and appeals, as may be reasonably requested in connection therewith.

(vi) In the event an Indemnified Party claims a right to payment pursuant hereto, such Indemnified Party shall send written notice to the appropriate Indemnifying Party. Such notice shall specify the basis for such claim. The failure by any Indemnified Party so to notify the Indemnifying Party shall not relieve the Indemnifying Party from any liability that it may have to such Indemnified Party with respect to any claim made pursuant to this Section 8.2(b)(iv) (except to the extent that the Indemnifying Party has suffered actual prejudice thereby), it being understood that notices for claims in respect of a breach of a representation or warranty must be delivered prior to the expiration of the survival period for such representation or warranty under Section 8.2(b)(vii). In the event the Indemnifying Party does not notify the Indemnified Party within thirty (30) days following its receipt of such notice that the Indemnifying Party disputes its liability to the Indemnified Party under this Section 8.2 or the amount thereof, the claim specified by the Indemnified Party in such notice shall be conclusively deemed a liability of the Indemnifying Party under this Section 8.2, and the Indemnifying Party shall pay the amount of such liability to the Indemnified Party on demand or, in the case of any notice in which the amount of the claim (or any portion of the claim) is estimated, on such later date when the amount of such claim (or such portion of such claim) becomes finally determined. In the event the Indemnifying Party has timely disputed its liability with respect to such claim as provided above, as promptly as possible, such Indemnified Party and the appropriate Indemnifying Party shall establish the merits and amount of such claim (by mutual agreement or in accordance with Section 9.4 hereof) and, within five (5) Business Days following the final determination of the merits and amount of such claim, the Indemnifying Party shall pay to the Indemnified Party in immediately available funds in an amount equal to such claim as determined hereunder.

(vii) No action or claim for Damages or otherwise under Section 8.2(a)(i) above or 8.2(a)(ii) arising out of, relating to or resulting from the transactions contemplated by this Agreement shall be brought or made after the expiration of the eighteen (18) month anniversary of the Closing Date; provided, however, that the foregoing time limitations shall not apply to any claims under Section 8.2(a)(i)(C), Section 8.2(a)(i)(D) (but with respect to claims under Section 8.2(a)(i)(D) solely to the extent arising from the failure to pay income or capital gain taxes or other personal taxes) or Section 8.2(a)(i)(E), or any claims which have been the subject of a good faith written notice from Buyer to the Shareholders or from the Shareholders to Buyer, as the case may be, prior to such period, which notice specifies in reasonable detail the nature and basis for such claim (which shall survive until the final resolution of such claims).

(c) Limitation of Liability. Notwithstanding any other provision of this Agreement, other than claims under Section 8.2(a)(i)(C), Section 8.2(a)(i)(D) (but with respect to claims under Section 8.2(a)(i)(D) solely to the extent arising from the failure to pay income or capital gain taxes or other personal taxes) or Section 8.2(a)(i)(E), the maximum aggregate amount for which Seller, the Company, the Shareholders, and any authorized transferee of any part of the Purchase Price shall be liable for any Damages or other losses to any party (including any third party) hereunder, whether arising out of or due to any breach of any representation or warranty, covenant or other agreement of Seller, the Company, the Shareholders, or any Affiliate thereof contained in this Agreement and in the related documents contemplated hereby, or any other Damages or losses arising out of or relating to the transactions contemplated hereby, whether for breach of contract, in tort or otherwise, shall be limited to and satisfied solely from the Indemnity Escrow Amount.

9.3 Successors and Assigns. The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns; provided, however, that no party may assign, delegate or otherwise transfer any of its rights or obligations under this Agreement without the prior written consent of the other parties hereto, except that Buyer may assign its rights hereunder (a) to any Affiliate of Buyer, or (b) as collateral security to any Person providing financing to Buyer or any Affiliate of Buyer but in either such case no such assignment shall relieve Buyer of any of its obligations hereunder.

9.4 Governing Law; Arbitration. This Agreement shall be governed by and construed in accordance with the Laws of Hong Kong, without giving effect to any choice or conflict of law provision or rule (whether Hong Kong or any other jurisdiction) that would cause the application of Laws of any jurisdiction other than Hong Kong. All disputes, controversies or differences arising out of or relating to this Agreement or the breach, termination or invalidity thereof, which cannot be settled by the parties through friendly consultations, shall be submitted to and exclusively and finally settled through arbitration conducted in Hong Kong under the auspices of the Hong Kong International Arbitration Centre (“HKIAC”) according to its rules (except as modified hereby). Arbitration shall be conducted by a tribunal consisting of three (3) arbitrators. One arbitrator shall be selected by Seller, one by Buyer, and the two arbitrators so selected shall select the third arbitrator. The language of the arbitral proceedings shall be English. The arbitration award shall be final and binding upon the parties. No party may contest the arbitration award or seek relief therefrom in any court. Any court having jurisdiction may enforce the arbitration award. Nothing herein contained shall bar any party from seeking equitable remedies in a court of appropriate jurisdiction to prevent or remedy a conduct potentially resulting in irreparable harm. Unless the HKIAC provides otherwise, the costs of the arbitration and of the parties (including reasonable costs of legal counsel) shall be borne by the losing party.

9.5 Entire Agreement. This Agreement, together with the exhibits and schedules attached hereto and any agreements entered into contemporaneously herewith, as well as the Head-Start Agreement and Amended and Restated Head-Start Agreement (to the extent referenced herein) and the Company’s Confidentiality Agreement dated on or about October 19, 2010, constitute the entire understanding of the parties with respect to the subject matter hereof, supersedes any prior agreements or understandings, written or oral, between the parties with respect to the subject matter hereof, and is not intended to confer upon any Person other than the parties hereto any benefit, right or remedy.

9.6 Further Assurances. Each party shall cooperate and take such action as may be reasonably requested by another party in order to carry out the provisions and purposes of this Agreement and the transactions contemplated hereby.

9.7 Amendment and Waiver. The parties may, by mutual agreement, amend this Agreement in any respect, and any party, as to such party, may: (a) extend the time for the performance of any of the obligations of any other party; (b) waive any inaccuracies in representations and warranties by any other party; (c) waive compliance by any other party with any of the agreements contained herein and performance of any obligations by any other party; and (d) waive the fulfillment of any condition that is precedent to the performance by such party of any of its obligations under this Agreement. To be effective, any such amendment or waiver must be in writing and be signed by the party against whom enforcement of the same is sought.

9.8 Counterparts. This Agreement may be executed in two or more counterparts, whether by facsimile or otherwise, each of which shall be deemed an original, but which together shall constitute one and the same instrument.

9.9 Enforcement. The parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached by any party. It is accordingly agreed that the non-breaching party shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, this being in addition to any other remedy to which the non-breaching party is entitled at law or in equity.

9.10 Headings. The headings preceding the text of the sections and subsections hereof are inserted solely for convenience of reference, and shall not constitute a part of this Agreement nor shall they affect its meaning, construction or effect.

9.12 Severability. Any provision hereof that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. To the extent permitted by law, each party hereby waives any provision of Law that renders any such provision prohibited or unenforceable in any respect.

9.13 Enforcement of Certain Rights. Nothing expressed or implied herein is intended, or shall be construed, to confer upon or give any Person other than the parties, and their successors or permitted assigns, any right, remedy, obligation or liability under or by reason of this Agreement, or result in such Person being deemed a third-party beneficiary hereof.
