4. In the event that a matter arises that would give rise to a claim of indemnification both by Silan against Sipex and by Sipex against Silan, then, to the extent of such overlapping claim of indemnification, Silan's obligation to indemnify Sipex shall prevail and Sipex shall not have the obligation to indemnify Silan (but only to the extent of such overlapping claim).

1. Rights Cumulative. The remedies provided in this Article 6 shall be cumulative and shall not preclude assertion by any Indemnitee of any other rights or the seeking of any and all other remedies against any Indemnifying Party.
2. Indemnification Payments. Indemnification required by this Article 6 shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or loss, liability, claim, damage or expense is incurred.

3. the legal sufficiency of any assignment, document or instrument delivered hereunder to convey title to any asset or thing of value upon its execution, deliver and filing.
2. Except as may expressly be set forth in any Transaction Agreement, all assets and rights to be transferred or licensed to Silan shall be transferred or licensed, as the case may be, "AS IS, WHERE IS" and without warranty of any kind. Except as may expressly be set forth in any Transaction Agreement, Silan shall bear the economic and legal risk that any conveyance shall prove to be insufficient to vest in Silan good and marketable title, free and clear of any lien, claim, equity or other encumbrance.

The Term of each Transaction Agreement shall be a set forth therein.

7.2   Termination of Agreement .

  Without limiting the termination rights otherwise provided in the other Transaction Agreements with respect to such other Transaction Agreements, where the following grants to a Party the right to terminate this Agreement or any of the Transaction Agreements, such Party may exercise such right by furnishing the other Party written notice to that effect, and such termination shall take effect upon the other Party's receipt thereof, subject to any cure or transition period that may otherwise apply hereunder.

-16-

1. Termination of Wafer Supply Agreement or PTTLA. This Agreement and the other Transaction Agreements shall immediately and automatically terminate upon the termination, but not the expiration of, the Wafer Supply Agreement or the PTTLA.
2. Mutual Agreement of the Parties. The Parties may agree in writing to terminate this Agreement or any other Transaction Agreement, as the case may be; or
3. An Uncured Material Breach. Subject to the terms of this Section 7.2(c), a Party may terminate this Agreement or any other Transaction Agreement in the event of a material breach by the other Party as set forth in this Section 7.2(c); provided that where the other Party's material breach is solely of one of the other Transaction Agreements, this Section 7.2(c) only provides the non-breaching party the right to terminate the Transaction Agreement so breached.
1. If either Party (the "Breaching Party") shall at any time materially breach this Agreement or any other Transaction Agreement, without any material causative fault on the part of the other Party (the "Non-Breaching Party"), the Non-Breaching Party may advise of its intention to terminate this Agreement or any other Transaction Agreement, as applicable, by providing formal written notice of breach to the Breaching Party specifying the breach. Notice for purposes of the foregoing that is provided other than in strict accordance with Section 9.5 will not be effective.
2. Notwithstanding the foregoing, this Agreement or the applicable other Transaction Agreements will not be terminated under this Section 7.2(c) if (A) the breach specified in the notice is remedied within the sixty (60) day period following receipt of the notice by the Breaching Party, or (B) if the breach reasonably requires more than sixty (60) days to correct, the Breaching Party has, within thirty (30) days from receipt of the notice of breach, begun substantial corrective action to cure the breach and submitted a written remediation plan to the Non-Breaching Party's Program Coordinator providing a detailed explanation of the steps to be taken to cure the breach as quickly as practicable, the Breaching Party diligently pursues such corrective action, and such breach is actually cured within ninety (90) days following receipt of the notice of breach.
3. If any breach is not cured within the time permitted in Section 7.2(c)(ii) above, the Non Breaching Party shall have the right to issue a notice of termination of this Agreement or the applicable other Transaction Agreement within ninety (90) days of the expiration of the foregoing cure period by giving written notice thereof to the Breaching Party. The Party receiving notice shall have the right to cure any such breach up to the date of termination.
4. Notwithstanding the foregoing, where a Party alleged to be in breach disputes the breach, neither this Agreement nor any other Transaction Agreement may be terminated under this Section 7.2(c) unless and until the existence of the breach is determined in accordance

   -17-

   with Article 8, and the Breaching Party is given the opportunity to cure the breach as set forth in this Section 7.2(c) following such determination.

4. Change in Control, Liquidation, Bankruptcy, etc. Upon the change in control of a Party or its parent company, the other Party may terminate this Agreement or any other Transaction Agreement. For the purposes of the foregoing a "change of control" of a Party shall mean the sale of more than fifty percent of the stock of a Party in a single transaction or a series of related transactions, the merger of a Party with another entity where the Party is not the surviving entity or a sale of all or substantially all of the assets of a Party to which this Agreement or any other Transaction Agreement relates. Either Party may terminate this Agreement or any other Transaction Agreement upon the liquidation, bankruptcy, receivership, custodianship or dissolution of the other Party (whether voluntarily or involuntarily).
5. Adverse Government Intervention. At any time during the Term, should any Governmental Authority take any action or inaction adverse to any Party, including, but not limited to any refusal to grant the benefits of any foreign capital inducement law in China or any other necessary government approval, or make recommendations to the Parties or any of them requiring directly or indirectly, formally or informally, alteration or modification of any term or condition of this Agreement or any other Transaction Agreement, in a manner that is material and adverse to one Party, within sixty (60) days from said action, inaction or recommendation of the Governmental Authority, the Parties hereto shall enter into good faith negotiations with the objective of restructuring the relationship between the Parties hereto in a manner such that the adverse effect of said alteration or modification of this Agreement and/or any other Transaction Agreement, as applicable, will be minimized. If the Parties cannot reach an acceptable modification to such agreements within three (3) months from the date of such written request, or within such longer period of time as mutually agreed upon, either Party shall have the right to terminate this Agreement or any other Transaction Agreement by giving written notice to that effect to the other Party. It is expressly understood and agreed by the Parties hereto that in the event of such termination, neither Party will incur any liability to the other Party for any alleged default or breach in the performance of this Agreement or any other Transaction Agreement arising from the exercise of the right herein provided to terminate this Agreement or any other Transaction Agreement as the case may be unless it can be established by a Party that the other Party acted in conjunction with said Governmental Authority to bring about the intended result. Except as provided in the previous sentence, compliance by either Party with this Section 7.2(e), shall not be deemed a breach under any provision of this Agreement or any other Transaction Agreement. In event of a conflict between this Section 7.2(e) and Section 9.2, this Section 7.2(e) shall prevail.

-18-

7.3   Effect of Termination .

1. Termination of this Agreement for any reason shall not release either Party from any liability accruing as of or before such termination.
2. The following provisions of this Agreement shall survive any termination of this Agreement: Sections 3.1(c) and 7.3, and Article 4 and Article 9. The representations and warranties of the Parties set forth in Article 5 of this Agreement shall survive until the two (2)-year anniversary of any termination of this Agreement; provided, however, that if written notice of a claim of breach of any such representations or warranties is given to a Party prior to the expiration of such two (2)-year period, the relevant representations and warranties shall survive as to such claim. The indemnification obligations of the Parties set forth in Article 6 shall survive any termination of this Agreement; provided that with respect to claims of indemnification that arise solely out of this Agreement (and not any of the other Transaction Agreements as incorporated by reference in Article 6), the indemnification obligations of the Parties set forth in Article 6 shall survive only until the two (2)-year anniversary of the termination of this Agreement; provided further, however, that if written notice of a claim for indemnification is given prior to the expiration of such two (2)-year period, the relevant indemnification obligation shall survive as to such claim.
3. Subject to the foregoing provisions of this Section 7.3, the rights and obligations under each of the other Transaction Agreements that survive termination of such other Transaction Agreements shall be solely as set forth therein.

ARTICLE 8
DISPUTE RESOLUTION

It is the intent of the Parties that any breach of this Agreement or any other Transaction Agreement be resolved in an amicable manner, to the fullest extent possible, and that any such resolution be reasonable in light of the rights and obligations of the Parties. If any breach should arise which cannot be resolved by the personnel of each Party directly involved, the following procedures of this Article 8 shall apply in each of the circumstances described below.

8.1   Conciliation Process .

  If a Party alleges breach of this Agreement or another Transaction Agreement by the other Party, and the other Party disputes the breach, then the Party alleged to be in breach has the right to demand the following meetings:

1. assessing the good faith basis for the claimed breach;

-19-

2. defining, assessing and prioritizing the alternatives reasonably available to cure such breach or to correct the circumstances or situations that gave rise to such breach so as to make its reoccurrence unlikely; and
3. adopting by unanimous vote, one or more curative or corrective courses of action.

8.3   Remedies .

  Subject to Sections 8.1 and 8.2, upon the failure to cure a material breach by either Party of any provision of this Agreement or any other Transaction Agreement, the Non-Breaching Party shall have the right to pursue all available remedies at law or in equity that it may elect, including but not limited to specific performance or injunctive relief, in order to obtain the benefits which have been provided pursuant to this Agreement and the other Transaction Agreements, or to obtain adequate recourse or compensation in the event the same are not so provided.

   -5-

   remedy against Sipex which shall be Silan's sole and exclusive remedy for such failure by Sipex: (i) Sipex shall make up the difference between its Order Commitment for the Shortfall Quarter and actual orders for the Shortfall Quarter (such difference the "Sipex Shortfall") by ordering Equivalent Wafers of Sipex Products in an amount equal to the Sipex Shortfall within the next Quarter (the "Order Makeup Quarter") in addition to its Order Commitment for such Makeup Quarter, and (ii) if by the end of such Makeup Quarter Sipex has not ordered its Order Commitment for that Makeup Quarter plus the full Sipex Shortfall for the Shortfall Quarter, then such failure shall be deemed a material breach of this Agreement by Sipex; provided that, if such failure occurs during the Commitment Term, Silan's sole and exclusive remedy and Sipex's sole and exclusive liability for such breach shall be Sipex's payment to Silan of the Order Shortfall Penalty as set forth under Sections 2.4(b) through 2.4(d) below.

2. "Order Shortfall Penalty" means a dollar amount equal to (A) one hundred percent (100%) of (B) the Wafer Price (adjusted in accordance with Sections 2.5 and 2.7(a)) for the Sipex Shortfall, but only to the extent such Sipex Products constituting the Sipex Shortfall were not ordered in the Makeup Quarter.
3. Silan shall invoice Sipex for the Order Shortfall Penalty within thirty (30) days of the end of the Makeup Quarter and Sipex shall pay such invoice within forty-five (45) days of receipt thereof. The Order Shortfall Penalty shall be net of any and all taxes.
4. In calculating the Shortfall Penalty, the yield used to adjust the Wafer Price in accordance with Section 2.7(a) shall be deemed to be the same average yield achieved for Equivalent Wafers of Sipex Products supplied in the Shortfall Quarter.
5. Sipex may notify Silan within thirty (30) days of the end of each Quarter whether there has been an Order Shortfall for such Quarter and whether, and to what extent, Sipex intended to make up such Order Shortfall in the following Quarter. If Sipex provides such notice, unless Silan notifies Sipex within five (5) business days of receiving such notice from Sipex to what extent it requires Sipex to make up the Order Shortfall in the Quarter in which the notice is received, Sipex shall not be obligated to pay the Order Shortfall Penalty to Silan for the Order Shortfall Quarter.

2.5   Failure to meet Supply Commitment .

1. If, in a Quarter (a "Supply Shortfall Quarter") Silan fails to supply the number of Equivalent Wafers of Sipex Products ordered by Sipex in accordance with Section 4.3 (the difference between the number of Equivalent Wafers of Sipex Products ordered by Sipex and the number actually supplied by Silan in such Quarter, the "Silan Shortfall"); and such amount ordered by Sipex in not more than Silan's Supply Commitment; and such failure by Silan to supply Sipex Products in accordance with the Silan Supply Commitment is not due to any material uncured breach of Sipex under this Agreement or any of the other Transaction Agreements;
2. Then, subject to Section 2.5(g), Silan shall attempt to remedy such supply failure by making available for purchase by Sipex in the next Quarter (the "Supply Makeup Quarter") Equivalent Wafers of Sipex Products in an amount equal to the Supply Commitment for such Supply Makeup Quarter plus the Silan Shortfall (Sipex may order up to such amount in its sole discretion and

   -6-

   shall be released from its Purchase Commitment for that Supply Makeup Quarter). If, at the end of such Supply Makeup Quarter, there is still a shortfall (such shortfall the "Final Supply Shortfall"), determined by subtracting (x) the actual number of Equivalent Wafer that Silan actually supplies to Sipex in the Supply Makeup Quarter from (y) the number of Equivalent Wafer that Sipex ordered during such Supply Makeup Quarter; then Silan shall be in material breach of this Agreement, provided that, if such breach occurs during the Commitment Term, Sipex's sole and exclusive remedy and Silan's sole and exclusive liability for such breach shall be Silan's payment to Sipex of the Supply Shortfall Penalty calculated as set forth in Sections 2.5(c) through 2.5(e) below.

3. Supply Shortfall Penalty. In accordance with Section 2.5(b), Silan will be required to pay to Sipex an amount (the "Supply Shortfall Penalty"), calculated as follows:

(i) If the amount of wafers delivered by Silan in any commitment quarter is less than [+], if Sipex has ordered [+] or more wafers, the Supply Shortfall Penalty is equal to (x) the number of Equivalent Wafers in the Supply Shortfall multiplied by (y) the Wafer Price (adjusted in accordance with Sections 2.5 and 2.7(a)) for the difference between the delivered amount of wafers and [+] wafers and [+] of the Wafer Price (adjusted in accordance with Sections 2.5 and 2.7(a)) and between [+] wafers and the amount of wafers ordered by Sipex .

(ii) If the amount of wafers delivered by Silan in any commitment quarter is greater [+], if Sipex has ordered [+] or more wafers, but less than the amount ordered by Sipex under the terms of this agreement then the Supply Shortfall Penalty is equal to the Final Supply Shortfall minus [+], multiplied by [+] of the Wafer Price (adjusted in accordance with Sections 2.5 and 2.7(a)).

4. Sipex shall invoice Silan for the Supply Shortfall Penalty within thirty (30) days of the end of the Makeup Quarter and Sipex shall pay such invoice within forty-five (45) days of receipt thereof. The Supply Shortfall Penalty shall be net of any and all taxes.
5. In calculating the Supply Shortfall Penalty, the yield used to adjust the Wafer Price in accordance with Section 2.7(a) shall be deemed to be the same average yield achieved for the Equivalent Wafer of Sipex Products supplied in the Supply Shortfall Quarter.
6. By way of example:
1. Example 1: In the Quarter 1 Sipex orders [+] Equivalent Wafers; Silan supplies only [+] Equivalent Wafers. Thus the shortfall is [+] Equivalent Wafers. In Quarter 2 (the Order Makeup Quarter), Sipex orders another [+] Equivalent Wafers and, Silan delivers all [+] Equivalent Wafers. Thus, there is no shortfall in Quarter 2, however [+] of these [+] Equivalent Wafers (i.e. [+] are attributed to the [+] Equivalent Wafer shortfall in Quarter 1. Thus, the Supply Shortfall Penalty (as set forth under Sections 2.5(c) through 2.5(e)) is [+] of the Wafer Price for [+] Equivalent Wafers (i.e., [+] of the Wafer Price for the balance of [+] Equivalent Wafers [+].

2. Example 2: In the Quarter 1 Sipex orders [+] Equivalent Wafers; Silan supplies [+] Equivalent Wafers. Thus the shortfall is [+] Equivalent Wafers. In Quarter 2 (the Order Makeup Quarter), Sipex orders another [+] Equivalent Wafers and, Silan delivers only [+] Equivalent Wafers. This second shortfall becomes the shortfall for Quarter 3 and Silan has failed to make up the shortfall for Quarter 1. Thus, the Supply Shortfall Penalty (as set forth under Sections 2.5(c) through 2.5(e)) is [+] of the Wafer Price for [+] Equivalent Wafers [+] of the Wafer Price [+] Equivalent Wafers [+].
3. Example 3: In the Quarter 1 Sipex orders [+] Equivalent Wafers; Silan supplies [+] Equivalent Wafers. Thus this Quarter the shortfall is [+] Equivalent Wafers. In Quarter 2 (the Order Makeup Quarter), Sipex orders another [+] Equivalent Wafers and, Silan delivers only [+] Equivalent Wafers. Thus for this Quarter the shortfall is [+] Equivalent Wafers which become the shortfall for Quarter 3 and because the number of Equivalent Wafers delivered did not exceed [+] none of the Equivalent Wafers delivered in Quarter 2 are credited to the shortfall in Quarter 1. Thus, the Supply Shortfall Penalty (as set forth under Sections 2.5(c) through 2.5(e)) is [+] of the Wafer Price for [+] Equivalent Wafers [+] of the Wafer Price [+] Equivalent Wafers [+].
4. Example 4: In the Quarter 1 Sipex orders [+] Equivalent Wafers; Silan supplies only [+] Equivalent Wafers. Thus the shortfall in Quarter 1 is [+] Equivalent Wafers. In Quarter 2 (the Order Makeup Quarter), Sipex orders another [+] Equivalent Wafers and, Silan delivers all [+] Equivalent Wafers. Thus, there is no shortfall in Quarter 2, Thus, the Supply Shortfall Penalty is [+] of the Wafer Price for the [+] Equivalent Wafers [+].
7. Silan may notify Sipex within thirty (30) days of the end of each Quarter whether there has been a Supply Shortfall for such Quarter and whether, and to what extent, Silan can make up such Supply Shortfall in the following Quarter. If Silan provides such notice, unless Sipex notifies Silan within five (5) business days of receiving such notice from Silan to what extent it requires Silan to make up the Supply Shortfall in the Quarter in which the notice is received, Silan shall not be obligated to pay the Supply Shortfall Penalty to Sipex for the Supply Shortfall Quarter.
8. Without limiting its rights under Article 7 and 9.2 of the Master Agreement or this Agreement, Silan shall have the option upon notice to Sipex to suspend in whole or in part its Supply Commitment under Section 2.3(b) if Silan would have the right to terminate this Agreement for a breach of this Agreement by Sipex. If Silan does not notify Sipex within thirty (30) days from the date it has the right to terminate or suspend this Agreement for breach by Sipex, that it wishes to suspend its Supply Commitment, Silan shall continue to be obligated under Section 2.3(b) to satisfy its Supply Commitment.

2.6   Sipex Product Pricing .

Subject to the terms of this Agreement (including this Section 2.6), the price to be paid by Sipex for Finished Sipex Products supplied hereunder shall be based on the Fixed Wafer Price for the relevant Sipex Product as set forth in Exhibit C-1 adjusted in accordance with Section 2.7. The Fixed Wafer Price includes the cost of Silan conducting a Wafer

-8-

Level Probe on each wafer but excludes any Die Level Probe costs. Payment terms for the Sipex Products supplied hereunder shall be as set forth in Article 7. The Fixed Wafer Price also excludes the cost of backside grinding and backside metal for wafers. For avoidance of doubt, unless explicitly agreed to in writing by Sipex, no change to any Sipex Process, whether for the purposes of meeting Process Qualification or Product Qualification, shall increase the Fixed Wafer Price of any Sipex Products as set forth in Exhibit C-1.

2.7   Adjustments to Fixed Wafer Price :

1. Minimum Wafer Probe Yield. Each Fixed Wafer Price assumes a minimum Wafer Probe Yield ("Minimum Wafer Probe Yield") as set forth in Exhibit C-1. To the extent the Actual Wafer Probe Yields are less than the Minimum Wafer Probe Yields, the Fixed Wafer Price shall be reduced in direct proportion to the percentage difference between the Actual Wafer Probe Yield and the Minimum Wafer Probe Yield (the "Wafer Price"). Any wafer of Finished Sipex Product with a Wafer Probe Yield of less than twenty-five percent (25%) will be returned as scrap for a full refund. For purposes of this Section 2.7, "Wafer Probe Yield" means the number of electrically good die in each wafer of Finished Sipex Product following the final packaging and testing of dies by Sipex or its designee (which excludes bad die identified in Sipex Product testing under Sections 5.1 and 5.2, divided by the expected number of die for the Sipex Wafer set forth in Exhibit C-2. In the event Silan disputes Sipex's Wafer Probe Yield, Sipex shall make the rejected die available to Silan for testing by an independent testing consultant in Santa Xxxxx County, California to verify the basis for any rejected die's failure.
2. Initial Wafer Price Reduction. As partial consideration for Sipex entering into this Agreement with Silan, the Wafer Price for the first [+] Equivalent Wafers of Finished Sipex Product purchased by Sipex hereunder shall be reduced by an amount equal to [+] United States Dollars US$[+]) for each 5-inch wafer and (ii) [+] for each 6-inch wafer.
3. Term of Wafer Pricing. The Fixed Wafer Price for each Sipex Product ordered by Sipex is set forth on Exhibit C-1 and shall be fixed for such Sipex Product for [+] years from the first commercial supply of such Sipex Product by Silan to Sipex hereunder (such period for each Sipex Product the "Initial Fixed Price Period"). At least ninety (90) days prior to the end of the Initial Fixed Price Period (and any Subsequent Fixed Price Period) for each Sipex Product, the Parties shall, subject to Section 2.7(d), commence good faith negotiations to set the Fixed Wafer Price for the relevant Sipex Product for a period of at least one year (each such subsequent period a "Subsequent Fixed Price Period") following the initial Fixed Price Period or any Subsequent Fixed Price Period, as the case may be. If the Parties are not able to agree on the Fixed Wafer Price for any Subsequent Fixed Price Period, then each Party shall have the right to terminate this Agreement and neither party shall have any further obligation to purchase or supply, as the case may be, hereunder.
4. Maximum Wafer Price Adjustment. The Fixed Wafer Price for any Subsequent Fixed Price Period shall not change by more than [+] of the Fixed Wafer Price for the Initial Fixed Price Period or prior Subsequent Price Period, as the case may be.

5. Additional Adjustments to Wafer Pricing. In setting a new Fixed Wafer Price, the Parties shall take into account among other things (i) reductions/increases in the cost of raw materials used, and (ii) reductions/increases in cost of operation of any process of manufacture used by Silan in manufacturing the Sipex Products.
6. Taxes. The price (including the Fixed Wafer Price) payable by Sipex to Silan for Sipex Products does not include any applicable VAT, sales and other similar taxes required by any Governmental Authority in China ("Sales Taxes"). Sipex shall be responsible for the payment of all such Sales Taxes imposed on the purchase of Sipex Products from Silan hereunder.
3. Product Qualification and Manufacturing Changes

3.1   Product Qualification.

3.3   Manufacturing Changes .

1. Once Product Qualification is successfully completed with respect to a Sipex Product, Silan shall not make any changes to the manufacturing process that do or could reasonably be expect to affect product quality, price, performance or yield for that Sipex Product (such change, a "Major Process Change") without Sipex's prior written consent. If Silan wishes to make a Major Process Change it shall inform Sipex in writing at least ninety (90) days in advance of the proposed change setting forth the nature of the change and Silan's reasons for wanting to make such change and any anticipated changes to the manufacturing costs or price of a Sipex Product resulting from such Major Process Change. Sipex shall respond it writing to Silan within five (5) Business Days of receiving such notice whether (i) Sipex approves such change, (ii) Sipex will not consent to such change being made, or (iii) Sipex requires additional information from Silan in order to approve or disapprove such change. If Sipex does not respond in five (5) Business Days in accordance with the foregoing, the Major Process Change as described in the Silan notice shall be deemed approved. If Sipex does respond within five (5) Business Days in accordance with the foregoing, Silan shall not make any Major Process Change unless it is approved by Sipex in writing. To the extent any manufacturing changes are made or allowed happen and Sipex approves any such changes, the Parties shall discuss in good faith an equitable solution to remedy any adverse effects that result from

   -11-

   or arise out of the change, including adverse effects to the Sipex Product, its yield, reliability or conformance to the Specification and the Parties also discuss in good faith an equitable sharing of all costs, including for re-qualifying the relevant Sipex Product where necessary, associated therewith. Notwithstanding the foregoing, Sipex shall not be responsible for any manufacturing cost increase or increase to the prices of the Sipex Products resulting from such change unless Sipex has approved such increases.

2. Except as set forth in Section 4.2(c) of the PTTLA, in no event shall Silan be required to indemnify and hold Sipex harmless under Article 6 of the Master Agreement for any Action or Liability for infringement of a third party's Intellectual Property Rights arising out of Sipex's sale or offer for sale of any Sipex Products not manufactured by Silan to the extent such Action or Liability is based on any Silan Process Technology Improvements and Sipex shall be solely liable for any such Action and Liability.
3. Forecasts, Purchase Orders and Production Holds

4.1   Rolling Forecasts .

On the fifteenth (15^th) day of each month (or on the last preceding Business Day prior to the fifteenth (15^th) day if the fifteenth (15^th) day is on a weekend or holiday) following the first Product Qualification, Sipex shall provide Silan with a non-binding, six (6) month rolling forecast (the "Forecast") of the monthly quantity of wafer starts and Wafer Outs, by Sipex Product (that have achieved Product Qualification), anticipated to be ordered by Sipex from Silan. The quantities set forth in each Forecast shall conform to the Supply Commitments under Section 2.3. Forecasts are for planning purposes only and Sipex shall only be liable with respect to those Sipex Products for which Sipex has submitted a Purchase Order therefor. For purposes of this Agreement, the term "Wafers Out" means the number of Finished Sipex Products.

4.2   Ordering Requirements and Forecast .

1. On a schedule mutually agreed between the Parties, Sipex shall issue to Silan a monthly Sipex Start Plan (the "Sipex Start Plan"). The Sipex Start Plan shall specify device types, and quantities in terms of wafer starts for Sipex Products the production of which is to commence for each of the days covered by the Sipex Start Plan (each a "Fixed Day") and whether the wafer starts shall be for 5-inch wafers or 6-inch wafers. Sipex shall issue each Sipex Start Plan (or any changes thereto) at least 24 hours in advance of the first date (China time) covered by such Sipex Start Plan. The Sipex Start Plan will be issued electronically. The Sipex Start Plan may be changed or updated by Sipex no more frequently than weekly on schedule mutually agreed between the Parties. Sipex shall use commercially reasonable efforts to balance wafer starts specified in each Sipex Start Plan such that wafer starts are allocated substantially uniformly during each month (for example wafer starts for any week are not more than 25% of Supply Commitment (for a week) or less than 25% of the Order Commitment (for a week)).
2. Silan shall commence production of such device types in such quantities as specified for each such Fixed Day. The remaining days of each Sipex Start Plan shall be for informational purposes only and shall not be deemed fixed to any extent.
3. Once per year Silan may shut down the Silan Facility for maintenance. Silan will provide Sipex with forty five (45) days advanced written notice of such shut down. The Parties

   -12-

   will use reasonable commercial efforts to reschedule the manufacture of Sipex Products scheduled to be manufactured in such shut down period. Silan's Supply Commitment for the Quarter in which the maintenance occurs shall be reduced by the fraction equal to twelve divided by thirteen (12/13) to reflect the one week of production loss during maintenance.

4.3   Purchase Order Process .

Three Weeks prior to the start of each Quarterly period, Sipex shall deliver to Silan a written, blanket purchase order for the Sipex Products expected to be started in that Quarter (each, a "Purchase Order"). Each Purchase Order shall set forth Sipex's anticipated wafer starts for each month during the Quarter and shall specify whether the anticipated wafer starts shall be for 5-inch wafers or 6-inch wafers. The monthly wafer starts specified in each Purchase Order shall be non-binding, provided that Sipex shall use commercially reasonable efforts to balance wafer starts specified in each Purchase Order and corresponding Sipex Start Plan in accordance with Section 4.2(a). In the event Silan reasonably believes that Sipex Start Plans are not balancing wafer starts during such months, the Parties agree to discuss in good faith changes to the Sipex Start Plan to balance wafer starts. Any terms and conditions expressed in any Purchase Order or acknowledgment, other than the relevant Sipex Product ordered, the quantities of Wafers Out, and the scheduled shipment date, shall have no force and effect between the Parties. Silan shall notify Sipex of its acceptance or, if Silan receives any Purchase Order that does not conform to the Ordering Requirements (as defined below), its rejection of each such Purchase Order thereof within two (2) Business Days of its receipt thereof. In the event Silan does not notify Sipex of its acceptance or rejection within such period, such Purchase Order shall be deemed accepted by Silan. Any rejection of any Purchase Order by Silan shall be accompanied by an explanation setting forth in reasonable detail, the basis for Silan's rejection thereof; provided that Silan may not reject a Purchase Order that conforms to Sipex's Forecast, the Supply Commitment and other ordering requirements as set forth under this Agreement ("Ordering Requirements"). Silan acknowledges that time is of the essence with respect to Silan's delivery of Finished Sipex Products in accordance with accepted Purchase Orders. Any Purchase Order accepted by Silan may not be cancelled or terminated, provided that Sipex shall be free to cancel any wafer starts set forth in any Sipex Start Plan in the event Silan is in uncured material breach of this Agreement or any of the other Transaction Agreements. Any Sipex Products cancelled under this Section 4.3 by Sipex, other than for an uncured material breach of this Agreement by Silan, shall count towards Silan's Supply Commitment.

4.4   Shipping Instructions .

On the day of each week as determined by the Program Coordinators, Sipex shall provide Silan a written report identifying wafer shipments (including shipment destinations) that need to be made in the current Week starting on that Monday (the "Shipping Instruction Report").

4.5   Revisions .

The Parties may agree in writing from time to time to revise the periods covered by the rolling forecasts, the forecasting and ordering process, the forecast and ordering data, and/or the technology by which the forecasts and orders are communicated to take advantage of more efficient and effective means of transacting business.

4.6   Production Holds .

At Sipex's request, Silan shall hold production on ten (10) Lots with respect to which production has started without charging Sipex an extra fee for that service for the first sixty (60) days of such hold. If Sipex desires Silan to hold production on Lots in excess of ten (10) Lots, Sipex shall pay Silan twenty percent (20%) of any such Lot's Fixed Wafer Price as reimbursement of Silan's costs and expenses of any such hold. If any hold on a Lot exceeds sixty

-13-

(60) days, Sipex, at its option, will either (i) terminate production of the Lot (which Lot shall not count against Sipex's Order Commitment Section 2.3 but will count towards Silan's Supply Commitment under Section 2.3), or (ii) release the Lot for completion of processing. In the event that production of a Lot which is on hold is terminated, the number of such terminated production wafers shall count toward Silan's Supply Commitment and Sipex shall pay Silan, as Silan's exclusive remedy and Sipex's sole Liability, an amount (the "Wafer Termination Amount") equal to:

(A) ((Fixed Wafer Price minus Wafer Substrate Cost) multiplied by Percentage Completion) plus (B) Wafer Substrate Cost.

where:

1. "Fixed Wafer Price" means the Fixed Wafer Price that would have been applicable in accordance with Article 3 had such wafer been purchased by Sipex;
2. "Percentage Completion" is the percentage of processing completed, determined based on the ratio of the sum of number of Process Steps actually completed to the total number of Process Steps required to produce the Sipex Product in finished, fully tested form;
3. "Process Steps" for each Sipex Product, the required number of process steps shall be deemed the sum of the following steps: (i) the Epi layer and (ii) the number of Maskworks layers for the relevant Sipex Product. For the purposes of the foregoing, process steps do not include (i) backside grinding or (ii) backside metal.
4. "Wafer Substrate Cost" means the costs incurred, as reflected in an invoice, by Silan to acquire the wafer for the Sipex Product in unfinished form.

4.7   Six Inch Wafers .

Silan shall notify Sipex when it is capable of manufacturing six-inch wafers. Until such time, all Sipex Products supplied hereunder shall be in the form of five-inch wafers.

4. Testing

5.1   Pre-Shipment .

Prior to any shipment of Sipex Products to Sipex or Sipex's designee (such as a third-party packaging house), Silan shall perform a Wafer Level Probe test on each wafer of Sipex Product and ensure each Sipex Product conforms to the Acceptance Criteria set forth on Exhibit C-4 or as otherwise agreed upon between the Parties.

5.2   Following Packaging .

Following the packaging of the Sipex Products, Sipex or its designee (such as a third-party packaging house) will perform further testing on the packaged Sipex Products for conformance with the Acceptance Criteria. Any packaged die that do not meet the Acceptance Criteria will be considered "bad die," unless the cause of the "bad die" is attributable solely to a cause other than Silan's manufacturing and processing, if the cause of the "bad die" is not solely attributable to Silan's manufacturing and processing, then Silan shall not be responsible for such "bad die."

5.3   Failure to Meet Acceptance Criteria .

Unless otherwise permitted by Sipex, Silan shall not ship to Sipex, and Sipex shall have no obligation to purchase or pay for, any Sipex Products that

-14-

do not meet the Acceptance Criteria. Sipex Products that do not meet the Acceptance Criteria shall not count against Silan's Supply Commitment under Section 2.3.

5. Shipping, Packaging and Return Procedure

6.1   Shipments .

Shipments shall be made by Silan from the Silan Facility (the "Shipping Point"), in accordance with the routing and "ship to" instructions in Sipex's Shipping Instructions Report and Section 6.3. All risk of loss or damage shall pass from Silan to Sipex upon the delivery of the Sipex Products to the Shipping Point. Title shall pass from Silan to Sipex only upon the delivery of the Sipex Products to the destination (the "Destination Point") specified in the Sipex's Shipping Instructions Report. Silan shall pay all out of pocket costs and expenses incurred in following Sipex's Shipping Instructions from Shipping Point to the Port of Destination but shall be reimbursed in full by Sipex to Silan for all such costs and expenses including but not limited to shipping, handling, export charges, taxes, duties, labor costs and similar amounts, and insurance costs or the shipment of the Sipex Products to the Port of Destination.  In the event that the Sipex Products are damaged or lost in shipment and such damage or loss is not due to Silan's failure to properly pack and ship such products in accordance with the Sipex's Shipping Instructions Report, (i) Sipex remedy shall be to make a claim against the insurer of such products for such damage and not against Silan (ii) for the purposes of Silan Supply Commitment such products shall be deemed to have been shipped by Silan.  The Parties shall cooperate in obtaining the necessary export and import clearances for each shipment For avoidance of doubt, in no event shall Silan be deemed in breach of this Agreement for Silan's failure or delay in shipping Sipex Products which breach is solely related to Silan following Sipex's routing and "ship to" instructions in Sipex's Shipping Instructions Report. Silan or the person appointed by Silan (such as freight forwarder) will deliver Sipex Product to the Port of destination designated by Sipex. However Sipex will be responsible for the import clearance and unloading of Sipex Products at the Port of destination.  Silan has the right to perform the above tasks or hire a third party to perform such task on its behalf. 

6.2   Delivery .

1. Silan shall ship Sipex Products on the dates specified in the Sipex Start Plan (the "Scheduled Shipment Date") to the extent that such date is no sooner than four business days after the date that would be possible to do so if Silan complies with the Cycle Time requirement hereunder following the start date specified in the Sipex Start Plan. Unless otherwise specified by Sipex, all Scheduled Shipment Dates shall be no later than sixty (60) days after the date of completed manufacturing of the relevant Sipex Products. In no event shall Silan ship Sipex Products sooner than three (3) days in advance of the Scheduled Shipment Date, unless requested in writing by Sipex or if such Sipex Products are designated as a Hot Lot by Sipex after specifying the Scheduled Shipment Date. Except for those Sipex Products which are subject to delays caused by holds, as described in Sections 4.6, in the event that any Sipex Products are not shipped in accordance with Scheduled Shipment Dates, Silan agrees to ship via air freight (or as directed by Sipex) and to pay for all extra costs. Silan shall be deemed to have met its delivery obligations for Finished Sipex Products to the extent any shipment is plus or minus ten percent (+/-10%) of line item quantity of the relevant Finished Sipex Product per Purchase Order that are due for delivery at that time.

-15-

2. If the ship date for Sipex Products is delayed, upon Sipex's request, by more than sixty (60) days from the date the Sipex Products are ready to be shipped by Silan (provided that such date is not prior to the date Silan is required to complete the manufacture of such Sipex Products in order to fulfill the relevant Sipex Start Plan), then, at the end of such sixty (60) day period, Silan may issue an invoice for such Products and Sipex shall pay such invoice within forty five (45) Business Days of Sipex's receipt of such invoice regardless of whether the Sipex Products have been shipped on Sipex's request during such period.
3. In addition to the Sipex packing and shipping instructions, the Sipex Products shall be packaged in accordance with applicable Sipex requirements and Chinese laws to ensure safe arrival at Sipex's designated delivery point. Sipex shall provide Silan with a copy of Sipex's packaging and shipment requirements.

2. Each box, crate or carton will show Sipex's full street address and Sipex Start Plans Lot number regardless of how shipped. On air carrier shipments, a packing list shall accompany each container and shall describe the contents of such container. On all other shipments, Silan will provide a packing list to accompany each shipment, referencing the appropriate Sipex Start Plans Lot number and Purchase Order number. The xxxx of lading also will reference the Sipex Start Plan Lot number and Purchase Order number.
3. Silan is responsible for packing shipments correctly based on the carrier/mode utilized. Charges for packing and crating shall be deemed part of the Price and no additional charges will be made therefor unless specifically requested by Sipex on the Sipex Start Plans. Silan agrees to ship via the carrier specified by Sipex.

6.4   Sipex Incoming Testing, Inspection and Acceptance .

1. Sipex may perform incoming inspection and tests on each shipment of Sipex Products following its receipt thereof. If any delivery of Sipex Products by Silan does not conform in any material respect to Sipex's order for such Sipex Products or is found not to conform with applicable Specifications furnished by Sipex or would not conform to the product warranty set forth in Section 9.1, Sipex shall have the right to return such Sipex Products to Silan for, in Sipex's discretion, rework or replacement. In addition, Sipex has the right to recommend corrective action to address variances from Specifications. Such return shipments shall be made by Sipex, EX Works (Incoterms 2000), Sipex's facilities.
2. Sipex shall notify Silan within five (5) Business Days of its receipt of any shipment whether Sipex intends to reject such shipment on the grounds that the Sipex Products are visibly shipping damaged or that the quantity in such shipment does not conform to the relevant Purchase Order, Start Plan or invoice, as applicable.

SPECIFICATIONS

Performance requirements for Product acceptance

1. Reliability test acceptance per JEDEC JESD47D, JESD22, JESD78

2. E-Test wafer level data per Sipex Stds.

3. Wafer sort data per Sipex Stds.

4. Package final test data per Sipex Stds.

For testing (2), (3), (4) Sipex will perform product characterization for each mask set and compare statistics to determine whether the performance of material from Silan fab is within the acceptable variations.

The characterization testing will include 3 temperatures: room, hot and cold per the data sheet specifications.

The data from units built from Sipex fab will be compared to units built from Silan fab for following statistical parameters:

1. Mean

2. Standard Deviation

3. Cpk

Sipex will determine that the performance is acceptable if the Cpks obtained from Silan units are equal to or better than Cpks obtained from Sipex material. For those Cpks that are worse, Sipex will evaluate the data to determine whether the values are acceptable or not. For those distributions that are not normal, mean and range will be used to determine acceptance.

For any product that has inferior performance compared to Sipex material, root cause will be determined and corrective action for improvement will be identified prior to acceptance. Sipex will assist Silan engineers in determining the root cause.

If an Exemption is obtained, Silan shall include any refund or reimbursement of any Royalty Withholding Taxes, Royalty Business Taxes, or other Royalty Taxes otherwise paid by Sipex or withheld from any Royalty payment, as part of Silan's next scheduled Royalty payment. Sipex shall pay or reimburse Silan for any costs and expenses incurred by Silan in applying for and obtaining the Exemption, provided such costs and expenses are approved in advance in writing by Sipex. Prior to incurring any such costs and expenses, Silan shall provide Sipex with a written notice detailing the source and the amounts of such costs and expenses. If Sipex fails to notify Silan of its agreement to pay such costs and expenses within ten (10) days of receipt of Silan's written notice thereof, Sipex shall be deemed to have not approved, and shall not be required to pay or reimburse Silan for, such amounts. Silan shall not be liable to Sipex for failure to apply for or obtain the Exemption based on Sipex's failure to approve in writing any such costs and expenses. For avoidance of doubt, in no event shall Silan be deemed in breach of this Agreement for failure to pay Sipex any Royalty payments under this Agreement during the period that Silan is applying for an Exemption under this Section 4.3 and none of such Royalty payments shall be subject to any interest payment penalty under Section 4.4.

4.4   Payment Terms .

  Silan Micro shall remit all Royalty payments to Sipex for each Royalty Period in immediately available funds to the account designated by Sipex ("Designated
