Item 2.01. Completion of Acquisition or Disposition of Assets.

On August 19, 2004, Amkor Technology, Inc., a Delaware corporation (“Amkor”), acquired approximately 93.0% of the capital stock of Unitive Inc., a Delaware corporation (“Unitive”), and on August 20, 2004, Amkor acquired approximately 60.0% of the capital stock of Unitive Semiconductor Taiwan Corporation (“UST”).

Amkor acquired the capital stock of Unitive pursuant to a Stock Purchase Agreement dated as of July 19, 2004 (the “Unitive Agreement”), by and among Amkor, Unitive, certain former stockholders of Unitive, certain former holders of options to purchase capital stock of Unitive, Onex American Holdings II LLC, David Rizzo, Thomas Egolf, Kenneth Donahue and U.S. Bank National Association. The consideration payable under the Unitive Agreement consists of a cash payment of approximately $12.3 million at closing, the assumption of approximately $5.7 million of debt at closing, an additional $15.5 million on the one-year anniversary of closing (payable in cash or in Amkor common stock at Amkor’s option) and a contingent payment of up to $55 million (payable in cash or in Amkor common stock at Amkor’s option) to be paid, if at all, upon the achievement of certain performance goals described in the Unitive Agreement. Unitive is a leading independent developer of electroplated wafer bumping technology and earlier this year announced the industry’s first electroplated lead-free wafer bumping process.

Amkor acquired the capital stock of UST pursuant to a Stock Purchase Agreement dated as of June 3, 2004 (the “UST Agreement”), by and among Amkor, UST, and certain shareholders of UST, as amended by a letter agreement dated July 9, 2004. The consideration payable under the UST transaction consists of a cash payment of approximately $19.4 million at closing, the assumption of approximately $16.3 million of debt at closing, the payment of approximately $450,000 in other costs and a variable contingent cash payment to be paid, if at all, based on the achievement of certain performance goals described in the UST Agreement, which payment is currently estimated to be approximately $2 million. In addition, Amkor has a call option to acquire the remaining approximate 40.0% of UST at any time over the next 18 months. Amkor is required to exercise the call option if UST achieves certain goals within such 18-month period. The exercise price of this option, which is currently estimated to be approximately $18.0 million, is based on a formula taking into account, among other things, the performance of UST. UST is a provider of electroplated wafer bumping services.

The terms of the acquisitions are more fully described in the Unitive Agreement and UST Agreement, as amended.

Item 9.01. Financial Statements and Exhibits.

Based on the Total Transaction Value to be paid by Buyer pursuant to the terms of this Agreement, the Earn-Out Percentages used for distribution pursuant to this Section 1.4(d) refer to those Earn-Out Percentages included on the applicable Consideration Schedule referenced beside the Total Transaction Value ranges set forth below. The "TOTAL TRANSACTION VALUE" shall be equal to the sum of (A) the Closing Consideration, (B) the First Anniversary Consideration, and (C) the Earn-Out Amount. For purposes of illustration only, if the Total Transaction Value equals $65,000,000, then the Earn-Out Percentages on Consideration Schedule G would be used to calculate the distribution of the Earn-Out Payment. -5-

Total Transaction Value Range Consideration Schedule - ----------------------------- ---------------------- < or = $29,999,999 C $30,000,000 - $39,999,999 D $40,000,000 - $49,999,999 E $50,000,000 - $59,999,999 F $60,000,000 - $69,999,999 G $70,000,000 - $74,999,999 H > or = $75,000,000 I The Buyer will distribute the Earn-Out Payment, if any, in the following preferential order: (i) Prior to any other distribution of the Earn-Out Amount, each Surrendering Series A-1 Optionee shall be entitled to receive, in addition to the amounts provided for in Sections 1.4(d)(ii) and 1.4(d)(iv) below, if any, an amount equal to the difference between (A) the product of (x) the number of Additional Surrendered A-1 Options for such Surrendering Series A-1 Optionee referenced on the applicable Consideration Schedule, multiplied by (y) a fraction, the numerator of which is the sum of (1) the Closing Consideration plus (2) the First Anniversary Consideration, and the denominator of which is the Aggregate Series A-1/A-2 Liquidation Amount, minus (B) the amount of Additional Series A-1 Exercise Price for such Surrendering Series A-1 Optionee referenced in the applicable Consideration Schedule (the aggregate amount payable to all Surrendering Series A-1 Optionees under this clause (i) shall be referred to herein as the "PREFERENTIAL OPTION CONSIDERATION"); provided that if the resultant amount of the Preferential Option Consideration exceeds the difference between the Earn-Out Amount minus the Investment Banking Fee, the Preferential Option Consideration shall be reduced to the amount equal to the Earn-Out Amount minus the Investment Banking Fee. (ii) After distribution of the Preferential Option Consideration, each Selling Stockholder and Surrendering Series A-1 Optionee shall be entitled to receive, in addition to the amount provided for in Section 1.4(d)(iv) below, if any, an amount equal to the product of (A) such Selling Stockholder's and Surrendering Series A-1 Optionee's applicable Series A-1/A-2 Earn-Out Percentage, multiplied by (B) the Earn-Out Amount, less the Investment Banking Fee, less the Preferential Option Consideration, provided that if the resultant amount of this clause (B) would otherwise be less than zero, then such amount shall be zero (the aggregate amount payable to all Selling Stockholders and Surrendering Series A-1 Optionees under this clause (ii) shall be referred to herein as the "SERIES A-1/A-2 EARN-OUT PREFERENCE"); provided, however, in the event that the Series A-1/A-2 Earn-Out Preference exceeds the Series A-1/A-2 Remaining Preference Amount (defined below), the Series -6-

A-1/A-2 Earn-Out Preference shall be equal to the Series A-1/A-2 Remaining Preference Amount. The "SERIES A-1/A-2 REMAINING PREFERENCE AMOUNT" shall be equal to (A) the product of (x) the sum of the Aggregate Series A-1/A-2 Shares plus the total number of Additional Surrendered A-1 Options as referenced on the applicable Consideration Schedule, multiplied by (y) $1.00, less (B) the sum of the Closing Consideration plus the First Anniversary Consideration. (iii) After the distribution provided for in Section 1.4(d)(ii), each Selling Stockholder and Surrendering Series A-3 Optionee shall be entitled to receive, in addition to the amount provided for in Section 1.4(d)(iv) below, if any, an amount equal to (I) with respect to each Selling Stockholder, the product of (A) such Selling Stockholder's applicable Series A-3 Earn-Out Percentage, multiplied by (B) (x) the Earn-Out Amount less the sum of (1) the Investment Banking Fee, (2) the Preferential Option Consideration and (3) the Series A-1/A-2 Earn-Out Preference, provided that if the resultant amount of this clause (B)(x) would otherwise be less than zero, then such amount shall be zero (the resultant amount of this clause (B)(x) shall be referred to herein as the "INTERIM EARN-OUT AMOUNT"), plus (y) the aggregate Additional Series A-3 Exercise Prices for all Surrendering Series A-3 Optionees referenced on the applicable Consideration Schedule, and (II) with respect to each Surrendering Series A-3 Optionee, the difference between (A) the product of (x) such Surrendering Series A-3 Optionee's applicable Series A-3 Earn-Out Percentage, multiplied by (y) the Interim Earn-Out Amount plus the aggregate Additional Series A-3 Exercise Prices for all Surrendering Series A-3 Optionees referenced on the applicable Consideration Schedule, minus (B) the amount of Additional Series A-3 Exercise Price for such Surrendering Series A-3 Optionee referenced on the applicable Consideration Schedule; provided, however, in the event that the Interim Earn-Out Amount exceeds the Series A-3 Preference Amount (defined below), the Interim Earn-Out Amount shall be equal to the Series A-3 Preference Amount. The "SERIES A-3 PREFERENCE AMOUNT" shall be equal to the product of (A) the sum of the Aggregate Series A-3 Shares plus the total number of Surrendered A-3 Options as referenced on the applicable Consideration Schedule, multiplied by (B) $1.00. (iv) After the distribution provided for in Section 1.4(d)(iii), each Selling Stockholder and Surrendering Optionee shall be entitled to receive an amount equal to the product of (A) such Selling Stockholder's and Surrendering Optionee's applicable Final Earn-Out Percentage, multiplied by (B) the Earn-Out Amount less the sum of (w) the Investment Banking Fee, (x) the Preferential Option Consideration, (y) the Series A-1/A-2 Earn-Out Preference, and (z) the Interim Earn-Out Amount, provided that if the resultant amount of this clause (B) would otherwise be less than zero, then such amount shall be zero (the aggregate amount payable to all Selling Stockholders and Surrendering Optionees under this clause (iv) shall be referred to herein as the "FINAL EARN-OUT AMOUNT"). (v) Notwithstanding anything in this Section 1.4 to the contrary, in no event shall Buyer be obligated to distribute in the aggregate any amount in excess of the Earn-Out Amount less the Investment Banking Fee pursuant to this Section 1.4. (e) EARN-OUT NOTICE. On the later to occur of (i) the One Year Anniversary Date or (ii) twenty (20) Business Days after the date on which the consolidated financial statements of the Company prepared in accordance with GAAP have been prepared as of and for the fiscal quarter ended -7-

March 31, 2005, but in any event with respect to this clause (ii) on or before July 31, 2005, Buyer shall deliver to the Onex Stockholder Representative a memorandum (the "EARN-OUT NOTICE") specifying in reasonable detail the calculation of the Earn-Out Amount, if any, and the calculation of the distribution of the Earn-Out Amount to each of the Selling Stockholders and Surrendering Optionees pursuant to Sections 1.4(d)(i), 1.4(d)(ii), 1.4(d)(iii) and 1.4(d)(iv), with the basis for such calculation and any supporting documentation, as applicable. (f) ONEX STOCKHOLDER REPRESENTATIVE OBJECTION. The Onex Stockholder Representative shall have forty-five (45) days to make an objection (in writing) to any item in the Earn-Out Notice, and such statement must be delivered to Buyer prior to 11:59 p.m. Eastern time on the last day of such forty-five (45) day period. The Onex Stockholder Representative may notify Buyer in writing at any time prior to the expiration of such forty-five (45) day period that it does not object to any item in the Earn-Out Notice, which notice shall trigger payment by Buyer in accordance with Section 1.4(d). During such forty-five (45) day period, Buyer shall provide the Onex Stockholder Representative and an accounting firm of national standing and reputation selected by the Onex Stockholder Representative (which firm shall be reasonably acceptable to the Buyer), upon reasonable advance notice and during regular working hours, full access to the books and records and the management of the Company to the extent relevant for the purpose of review of the Earn-Out Notice and verification of the calculations set forth therein. The cost of such review, including the expenses of any accounting firm, shall be borne by the Indemnifying Stockholders, who shall bear such costs based on their Indemnity Pro Rata Portion, unless the results of such review, which shall have either been agreed to by the Buyer or shall have been determined to be correct after application of the arbitration provisions of Section 8.3(f)(iii) hereof, reveal that the Buyer's calculation of the Earn Out Amount was inaccurate in the favor of Buyer by more than 2.5% of the actual amount, in which case Buyer shall pay such costs and expenses to the extent they are reasonable and documented in reasonable detail. Any such costs of review borne by the Indemnifying Stockholders shall be deducted from the Earn-Out Payment (to the extent thereof) prior to distribution and paid by Buyer to the Onex Stockholder Representative, and, to the extent the Onex Stockholder Representative has not previously advanced such amount to the accounting firm providing such review (and/or other appropriate recipients thereof), Onex shall remit such amount to such accounting firm (and/or other appropriate recipients thereof); provided that the Onex Stockholder Representative shall have first provided to Buyer an executed certificate providing a detailed listing of such costs and attesting as to its accuracy. The Onex Stockholder Representative and any accounting firm performing such review shall be subject to non-disclosure obligations reasonably satisfactory to the Buyer. (g) RESOLUTION OF CONFLICTS. (i) In case the Onex Stockholder Representative shall have objected in writing to the Earn-Out Notice in a timely manner or in case of any other dispute relating to the Earn-Out Amount, the Onex Stockholder Representative and Buyer will attempt in good faith to resolve such objection or dispute. Buyer shall promptly make payment of that portion (if any) of the Earn-Out Amount not subject to such dispute and retain only the disputed portion of the Earn-Out Amount until such dispute is resolved in accordance with this Section 1.4(g). If the Onex Stockholder Representative and Buyer should so agree, a memorandum setting forth such agreement will be prepared and signed by -8-

both parties, and any payments to be made as set forth therein shall be made on the terms provided therein. (ii) In the event the parties cannot come to an agreement as set forth in Section 1.4(g)(i) within thirty (30) days after the date on which the Onex Stockholder Representative objected in writing to the Earn-Out Notice or, in the event the dispute does not relate to an Earn-Out Notice, the date on which the parties determine that they are unable to reach agreement pursuant to Section 1.4(g)(i), such dispute shall be resolved in the manner set forth in Section 8.3(f). (h) EARN-OUT OPERATIONS. Buyer agrees that the operation of the Company during the period beginning on the Closing Date and ending on March 31, 2005 (the "EARN-OUT PERIOD") shall be governed by the provisions set forth at EXHIBIT D (the "EARN-OUT OPERATIONS PARAMETERS"). Without limiting the foregoing, Buyer agrees not to take any other action that would frustrate the spirit of the transaction and the Earn-Out contemplated hereunder. Buyer acknowledges that compliance with this Section 1.4(h) is intended to protect the interests of the Selling Stockholders in maximizing the Earn-Out Amount. If Buyer fails to comply with any of the provisions or the intent of the Earn-Out Operations Parameters, or takes other actions to frustrate the spirit of the transaction and the Earn-Out contemplated hereunder, the Selling Stockholders shall have the right to pursue a claim in accordance with the terms of this Agreement for Losses (which shall include, without limitation, any reduction in the Earn-Out Amount which results, directly or indirectly, from such failure to comply). Any disputes regarding this Section 1.4(h) (including any dispute regarding whether Buyer has complied with the Earn-Out Operations Parameters) shall be resolved in the manner set forth in Section 8.3(f). (i) TRANSFER LIMITATIONS. No Selling Stockholder may sell, exchange, transfer or otherwise dispose of his, her or its right to receive any portion of the Earn-Out Amount, other than (i) by the laws of descent and distribution or succession or by operation of law or (ii) if such Selling Stockholder or Surrendering Optionee shall have furnished Buyer with an opinion of counsel reasonably satisfactory to the Buyer that such disposition will not require registration of such portion of the Earn-Out Amount under the Securities Act, and the attempted transfer in violation of this Section 1.4(i) shall be null and void and shall not be recognized by Buyer. No Surrendering Optionee may sell, exchange, transfer or otherwise dispose of his, her or its right to receive any portion of the Earn-Out Amount other than by the laws of descent and distribution or succession or by operation of law, and the attempted transfer in violation of this Section 1.4(i) shall be null and void and shall not be recognized by Buyer.

(c) Any Registrable Securities received by the Selling Stockholder, if any, will be acquired for such Selling Stockholder's own account and not with a view to, or intention of, distribution thereof in violation of the Securities Act, any applicable state securities laws or foreign securities laws, and the Selling Stockholder will not dispose of the shares of such Registrable Securities in contravention of the Securities Act or any applicable state securities laws or foreign securities laws. (d) In the event such Selling Stockholder is eligible to receive Registrable Securities hereunder, such Selling Stockholder is either: (i) an "accredited investor" as such term is defined in Rule 501 of Regulation D of the Securities Act; or (ii) not a "U.S. Person" as that term is defined in Regulation S promulgated under the Securities Act ("REGULATION S") and has a legal residence outside the United States. (e) Prior to the Closing, the Selling Stockholder will provide Buyer with such information concerning any prior investment experience, business or professional experience and other information as Buyer may reasonably deem necessary to further evaluate the foregoing representations, including a customary investor questionnaire with reasonably acceptable answers thereon, as to such Selling Stockholder's investor status.

(g) The Selling Stockholder is able to bear the economic risk of its investment in Buyer Common Stock for an indefinite period of time.

(h) The Selling Stockholder has had an opportunity to ask questions and receive answers concerning the terms and conditions of the potential offering of the Buyer Common Stock, has had full access to such other information concerning Buyer as such Selling Stockholder has requested. (i) The name, address and shareholdings in the Company of the Selling Stockholder as listed on Section 2.2(a) and Section 2.2(b) of the Company Disclosure Schedule are true and correct in all material respects, and such address constitutes such Selling Stockholder's principal address for the purpose of determining the applicability of any state, local or foreign securities laws. 3.6 NON-U.S. PERSON. If the Selling Stockholder has a legal residence outside the United States and is not a "U.S. Person" as that term is defined in Regulation S or an "accredited investor" as such term is defined in Rule 501 of Regulation D of the Securities Act, such Selling Stockholder represents and warrants that he or it is not acquiring the Buyer Common Stock issued pursuant to the Acquisition for the account or benefit of a U.S. Person.

No information or knowledge obtained in any investigation pursuant to this Section 5.3 or otherwise shall affect or be deemed to modify any representation or warranty contained herein or the conditions to the obligations of the parties to consummate the Acquisition in accordance with the terms and provisions hereof. 5.4 REQUIRED APPROVALS AND EXEMPTIONS; REASONABLE EFFORTS.

Each party hereto, at the request of another party hereto, shall execute and deliver such other instruments and do and perform such other acts and things as may be necessary or desirable for effecting completely the consummation of the Acquisition and the Contemplated Transactions. 5.5 CONFIDENTIALITY. Each of the parties hereto hereby agrees that the information obtained in any investigation pursuant to the negotiation and execution of this Agreement or the effectuation of the Contemplated Transactions shall be governed by the terms of the Confidential Information Agreement dated as of May 13, 2004 (the "CONFIDENTIALITY AGREEMENT") between the Company and Buyer. Without limiting the foregoing, the Company and Selling Stockholders agree that, except with the prior -56-

written permission of the Buyer, they shall at all times hold in confidence and trust and not use or disclose any confidential information of (x) the Company provided to or learned by them prior to the Closing or provided to them by Buyer or the Company after the Closing or (y) Buyer provided to or learned by it in connection with the due diligence process in connection with Contemplated Transactions and the drafting and negotiation of this Agreement and the Related Agreements. Notwithstanding the foregoing, the confidentiality restrictions of this Section 5.5 shall not apply to information that (i) was in the public domain at the time it was disclosed or has entered the public domain through no fault of the receiving party, (ii) is disclosed pursuant to the order or requirement of a court, administrative agency, or other Governmental Entity; provided, however, that the receiving party shall provide prompt notice of such court order or requirement to the disclosing party to enable the disclosing party to seek a protective order or otherwise prevent or restrict such disclosure, (iii) with respect to information described in clause (y) above, was known by the receiving party at the time it is disclosed, (iv) is subsequently lawfully disclosed to the receiving party by a third party not bound by obligations of confidentiality or (v) is used by a Selling Stockholder who is an employee of the Company or Buyer in the performance of services for the Company after the Closing. 5.6 PUBLIC DISCLOSURE. Except to the extent required by Applicable Legal Requirements, no party shall issue any statement or communication to any third party (other than their respective agents) regarding the subject matter of this Agreement or the transactions contemplated hereby, including, if applicable, the termination of this Agreement and the reasons therefor, without the consent of the other parties, which consent shall not be unreasonably withheld, provided, however, that this restriction shall not prevent any party from making any disclosure that is necessary or appropriate to comply with applicable laws or regulations; and provided, further, that this restriction shall not prevent Buyer, the Company or Onex American Holdings II LLC (or Onex Corporation) from issuing a press release after the execution of this Agreement with respect to this Agreement or the transactions contemplated hereby provided such press release has been approved by the other parties referenced in this proviso (excluding Onex Corporation), which approval shall not be unreasonably withheld. 5.7 EXPENSES. Whether or not the Acquisition is consummated, all fees and expenses incurred in connection with the Acquisition including, without limitation, all legal, accounting, financial advisory, consulting and all other fees and expenses of third parties incurred by a party in connection with the negotiation and effectuation of the terms and conditions of this Agreement and the Contemplated Transactions ("THIRD PARTY EXPENSES"), shall be the obligation of the respective party incurring such fees and expenses. The Company shall pay its Third Party Expenses prior to Closing to the extent possible, and to the extent not possible, shall properly accrue any such Third Party Expenses on its books and records. If the amount of actual and anticipated Third Party Expenses listed on Section 2.20 of the Company Disclosure Schedule updated as of the Closing with the Company's then current reasonable estimate of all Third Party Expenses actually incurred and expected to be incurred by the Company or any of its Subsidiaries in connection with the negotiation and effectuation of the terms and conditions of this Agreement and the transactions contemplated hereby (which updated amount the Company shall provide in writing to Buyer prior as of Closing) exceeds $1,250,000 (the "EXPENSE CAP"), the amount of such excess (such amount, the "CLOSING EXCESS EXPENSES") shall reduce the Closing Consideration. If it is determined after the Closing, in accordance with the provisions of Article VIII, that the Third Party Expenses of the Company exceed the Expense Cap or exceed the -57-

Expense Cap in an amount greater than as determined at Closing, the amount of such excess not already reduced from the Consideration shall, notwithstanding any provision of this Agreement to the contrary, be withheld by Buyer from and shall reduce the amount of First Anniversary Consideration. Such amount, exclusive of the Closing Excess Expenses, is referred to as the "EXCESS THIRD PARTY EXPENSES". 5.8 TERMINATION OF BENEFIT PLANS. Effective prior to the Closing (such date, the "TERMINATION DATE"), the Company and ERISA Affiliates, as applicable, shall each terminate any and all group severance, separation or salary continuation, programs or arrangements (unless Buyer provides written notice to the Company at least five days prior to the Closing that such plans shall not be terminated) (collectively, "COMPANY DEFERRAL PLANS"). Unless Buyer provides such written notice to the Company, the Company shall provide Buyer at the Closing with evidence that such Company Deferral Plan(s) have been terminated (effective as of the Termination Date) pursuant to resolutions of the Company's or its ERISA Affiliates (as may be applicable) Board of Directors. The form and substance of such resolutions shall be subject to prior review and approval of Buyer, which approval shall not be unreasonably withheld. The Company and its Subsidiaries also shall take such other actions in furtherance of terminating such Company Employee Plan(s) as Buyer may reasonably require. 5.9 RELEASE OF LIENS. The Company shall file, or shall have filed, all agreements, instruments, certificates and other documents, in form and substance reasonably satisfactory to Buyer, that are necessary or appropriate to effect the release of all Liens set forth in Schedule 5.9 to this Agreement. 5.10 DELIVERY OF ADDITIONAL INFORMATION. Each party hereto shall deliver or make available to the other parties any information that such party may reasonably request, including but not limited to, in the case of the Company and Buyer, audited financial statements on a consolidated basis, in order to effectuate filings, notices, petitions or statements required by any Governmental Body in connection with the Acquisition and the transactions contemplated hereby, including, without limitation, any filings required under the Securities Act, the Exchange Act, or any rules and regulations of the SEC. 5.11 NOTIFICATION OF CERTAIN MATTERS. Each of the Company and the Buyer shall give prompt notice to the other of: (i) the occurrence or non-occurrence of any event, the occurrence or non-occurrence of which would reasonably be expected to cause any representation or warranty of the Company or Buyer, as the case may be, contained in this Agreement to be untrue or inaccurate at or prior to the Closing, and (ii) any failure of the Company or Buyer, as the case may be, to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it hereunder; provided, however, that the delivery of any notice pursuant to this Section 5.11 shall not (a) limit or otherwise affect any remedies available to the party receiving such notice or (b) constitute an acknowledgment or admission of a breach of this Agreement. Without limiting the provisions of Section 8.5(h), no disclosure by the Company or Buyer as the case may be pursuant to this Section 5.11, however, shall be deemed to amend or supplement the Company Disclosure Schedule or prevent or cure any misrepresentations, breach of warranty or breach of covenant. 5.12 ADDITIONAL DOCUMENTS AND FURTHER ASSURANCES. If, at any time after the Closing Date, Buyer shall reasonably determine that any deeds, bills of sale, assignments or assurances or other documents or instruments or any other acts or things are reasonably necessary or proper (a) to vest, -58-

perfect or confirm, of record or otherwise, in Buyer, its right to, and title or interest in, the Company Capital Stock transferred by the Selling Stockholders or (b) otherwise to carry out the purposes of this Agreement, Buyer shall so advise the Onex Stockholder Representative and the Non-Onex Stockholder Representative in writing, and the Selling Stockholders thereupon shall execute and deliver all such deeds, bills of sale, assignments and assurances and other documents and instruments and do all such other acts and things reasonably necessary, desirable or proper to vest, perfect or confirm Buyer's right, title or interest in, to or under the Company Capital Stock transferred by the Selling Stockholders, and otherwise to carry out the purposes of this Agreement.

(b) Buyer and the Company agree that the Consideration paid by Buyer and the liabilities of the Company, along with any other relevant items, will be allocated to the assets of Company for all purposes (including U.S. income tax and U.S. GAAP purposes) in a manner consistent with the provisions under Sections 338 and 1060 of the Code and the regulations promulgated thereunder. (c) Buyer and the Company shall file all required U.S. and non-U.S. Tax Returns (including amended returns and claims for refund) and information reports in a manner consistent with the allocations established in Section 5.13(b) of this Agreement. 5.14 DIRECTORS AND OFFICERS' INDEMNIFICATION. (a) Except to the extent required by applicable Legal Requirement, Buyer agrees that for a period of six (6) years after the Closing, it shall not, and shall not permit the Company to, amend, repeal or modify any provision in the Company's Organizational Documents relating to exculpation or indemnification of present or former officers and directors of the Company (or any indemnification or similar agreement in effect between the Company and any such officer or director without the written consent of such officer or director), it being the intent of the parties that the officers and directors of the Company prior to the Closing shall continue to be entitled to such exculpation and indemnification and to the benefit of any such agreement to the fullest extent permitted under the law of the Company's jurisdiction of incorporation and other applicable Legal Requirements; provided, however, that nothing in this Section 5.14 shall be construed to limit the ability of the Company to merge or consolidate with or sell all or substantially all of its assets to another entity; provided, that in the event of a merger or consolidation, the surviving entity shall honor the indemnity obligations of the Company. -59-

(b) The Company shall maintain, and Buyer shall cause the Company to maintain, at no additional expense to Buyer or the Company, the officers' and directors' liability insurance policies in effect as of the date of this Agreement for a period of six (6) years after the Closing, with respect to actions and omissions occurring prior to the Closing Date, on terms which are at least as favorable, including at least the same coverage, as the terms of such insurance policies in effect on the date hereof. The expense of such policies shall be borne by the Company and shall be deemed a Third Party Expense hereunder. 5.15 CERTAIN ACTIONS BY BUYER. Buyer shall not cause the Company to merge with another entity, regardless of whether the Company or such other entity survives such merger, until the first business day following the Closing Date. 5.16 280G APPROVAL(a) .

(a) FIRST ANNIVERSARY SHARES. (i) If Buyer elects pursuant to Section 1.3(b) hereof to issue Buyer Common Stock as part of the First Anniversary Consideration (the "FIRST ANNIVERSARY SHARES"), then, as soon as practicable after the date the First Anniversary Shares become issuable pursuant to Section 1.3(b) (and in no event more than five (5) Business Days thereafter), Buyer shall have registered all of such shares with the SEC on Form S-1 or S-3 so as to permit the resale of the First Anniversary Shares.

(ii) If the registration of which Buyer under this clause (b) gives notice is for a registered public offering involving an underwriting, Buyer shall so advise the Holders. In such event, the right of any Holder to registration pursuant to clause (b) shall be conditioned upon such Holder's participation in such underwriting and the inclusion of Registrable Securities in the underwriting shall be limited to the extent provided herein. All Holders proposing to distribute their securities through such underwriting shall (together with Buyer and the other holders distributing their securities through such underwriting) enter into an underwriting agreement in customary form with the managing underwriter selected for such underwriting by Buyer. If any Holder disapproves of the terms of any such underwriting, such person may elect to withdraw therefrom by written notice to Buyer. (c) In the case of each registration effected by Buyer pursuant to this Section 5.17(a) or (b), Buyer will keep each Holder advised in writing as to the initiation of such registration and as to the completion thereof. Buyer will: (i) Prepare and file with the SEC a Registration Statement (or amendment thereto) with respect to such securities and use its reasonable efforts to cause such Registration Statement to become and remain effective from the later of (i) the date on which Registrable Securities are first included therein and (ii) the date the Registrable Securities are issued for at least 180 days or, if earlier, until the distribution described in the Registration Statement has been completed; (ii) Furnish to the Holders participating in such registration and to the underwriters of the securities being registered such reasonable number of copies of the Registration Statement, preliminary prospectus, final prospectus and such other documents as such persons may reasonably request in order to facilitate the public offering of such securities; (iii) Prepare and file with the SEC such amendments and supplements to such Registration Statement and the prospectus used in connection with such Registration Statement as may be necessary to keep such Registration Statement effective and to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such Registration Statement; -61-

(iv) Use its commercially reasonable efforts to register and qualify the securities covered by such Registration Statement under such other securities or blue sky laws of such jurisdictions as shall be reasonably requested by the Holders, provided that Buyer shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of process in any such states or jurisdictions; (v) Promptly notify each Holder of Registrable Securities covered by such Registration Statement at any time when a prospectus relating thereto is required to be delivered under the Securities Act of the happening of any event as a result which the prospectus included in such Registration Statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then made; (vi) Cause all Registrable Securities registered pursuant to this Agreement to be listed on each securities exchange or market on which similar securities issued by Buyer are then listed; (vii) On or before the effective date of the Registration Statement, furnish to Buyer's transfer agent unlegended certificates representing ownership of the Registrable Securities being sold; and (viii) Make available, at the cost of the Holders (except for attorneys' fees and disbursements which are Registration Expenses) and during normal business hours upon reasonable advance notice, for inspection by the Holders and their attorneys and accountants, all financial and other records and other information, pertinent corporate documents and properties of Buyer and its subsidiaries, as shall be reasonably necessary to enable the Holders to exercise their due diligence responsibilities; provided however, that any such records and other information disclosed by Buyer pursuant to this clause (viii) shall be subject to the confidentiality provisions of Section 5.5. (d) Subject to paragraph (e) below, in the event (i) of any request by the SEC or any other federal or state governmental authority during the period of effectiveness of the Registration Statement for amendments or supplements to such Registration Statement or related prospectus or for additional information; (ii) of the issuance by the SEC or any other federal or state governmental authority of any stop order suspending the effectiveness of a Registration Statement or the initiation of any proceedings for that purpose; (iii) of the receipt by Buyer of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Registrable Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; (iv) of any event or circumstance not otherwise covered by clause (v) below which, upon the advice of its counsel, necessitates the making of any changes in a Registration Statement or prospectus, or any document incorporated or deemed to be incorporated therein by reference, so that they will not contain any untrue statement of a material fact or any omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading; or (v) Buyer determines in good faith that offers and sales pursuant to a Registration Statement should not be made by reason of the presence of material undisclosed circumstances or developments with respect to which the disclosure would be required in such a Registration Statement or related prospectus, is reasonably likely to have a seriously -62-

detrimental effect on Buyer, then Buyer shall deliver a certificate in writing to the Holders (the "SUSPENSION NOTICE") to the effect of the foregoing and, upon receipt of such Suspension Notice, the Holders shall refrain from selling any Registrable Securities pursuant to the Registration Statement (a "SUSPENSION") until the Holders have received copies of a supplemented or amended prospectus prepared and filed by Buyer, or until they are advised in writing by Buyer that the current prospectus may be used, and have received copies of any additional or supplemental filings that are incorporated or deemed incorporated by reference in any such prospectus. In the event of any Suspension, Buyer shall use commercially reasonable efforts to cause the use of the prospectus so suspended to be resumed as soon as reasonably practicable after the delivery of a Suspension Notice to the Holders. (e) Notwithstanding the foregoing, (i) no Suspension shall continue for more than 90 days, and (ii) Buyer shall not deliver more than two Suspension Notices under clause (v) of Section 5.17(d) in any twelve-month period. (f) Provided that a Suspension is not then in effect, each Stockholder may sell Registrable Securities under a Registration Statement, provided, to the extent required by applicable law, that it arranges for delivery of a current prospectus to the transferee of such securities. Upon receipt of a reasonable request therefor, Buyer shall provide an adequate number of current prospectuses to the Stockholder Representatives. (g) EXPENSES OF REGISTRATION. All Registration Expenses incurred in connection with all registrations pursuant to Section 5.17 shall be borne by Buyer. All Selling Expenses relating to securities registered on behalf of the Holders and all other registration expenses shall be borne by the Holders on a pro rata basis based on the number of Registrable Securities included in the registration. Any fees and disbursements of one counsel for the selling Holder(s) selected by them by majority vote, in excess of $35,000, shall be borne by the Holders on a pro rata basis, based on the number of Registrable Securities included in the registration. (h) INFORMATION. Each Holder shall furnish to Buyer such information regarding such Holder, the shares of Buyer Common Stock held by them and the distribution proposed by such Holder as Buyer may reasonably request in writing and as shall be required in connection with any registration referred to in this Agreement. (i) INDEMNIFICATION. In the event any shares of Buyer Common Stock are included in a Registration Statement under this Section 5.17: (i) To the extent permitted by law, Buyer will indemnify and hold harmless each Holder, its officers and directors, any underwriter (as defined in the Securities Act) for such Holder and each person, if any, who controls such Holder or underwriter within the meaning of the Securities Act or the Exchange Act, against any losses, claims, damages, liabilities (joint or several), costs (including, without limitation, costs of investigation, preparation and reasonable attorneys' fees) and expenses (collectively, "REGISTRATION LOSSES") to which they may become subject under the Securities Act, the Exchange Act or other federal or state law, insofar as such Registration Losses arise out of or are based upon any of the following statements, omissions or violations (collectively a "VIOLATION"): (i) any untrue statement or alleged untrue statement of a material fact contained in such Registration -63-

Statement, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto, (ii) the omission or alleged omission to state therein a material fact required to be stated therein, or necessary to make the statements therein not misleading, or (iii) any violation or alleged violation by Buyer of the Securities Act, the Exchange Act, any state securities law or any rule or regulation promulgated under the Securities Act, the Exchange Act or any state securities law; provided, however, that the indemnity agreement contained in this subsection (i) (i) shall not apply to amounts paid in settlement of any such Registration Loss if such settlement is effected without the consent of Buyer (which consent shall not be unreasonably withheld), nor shall Buyer be liable in any such case for any such Registration Loss to the extent that it arises out of or is based upon a Violation which occurs in reliance upon and in conformity with written information furnished expressly for use in connection with such registration by or on behalf of any such Holder. (ii) To the extent permitted by law, each selling Holder (severally and not jointly) will indemnify and hold harmless Buyer, each of its directors, each of its officers who has signed the Registration Statement, each person, if any, who controls Buyer within the meaning of the Securities Act, any underwriter, any other Holder selling securities in such Registration Statement and any controlling person of any such underwriter or other Holder, against any Registration Losses to which any of the foregoing persons may become subject, under the Securities Act, the Exchange Securities Act or other federal or state law, insofar as such Registration Losses arise out of or are based upon any Violation, in each case to the extent (and only to the extent) that such Violation occurs in reliance upon and in conformity with written information furnished by such Holder expressly for use in connection with such registration; provided, however, that the indemnity agreement contained in this subsection (i) (ii) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Holder, which consent shall not be unreasonably withheld; provided, that, in no event shall the aggregate liability of any Holder pursuant to this subsection (i) (ii) and Section 5.17(i)(iv) exceed the net proceeds from the offering received by such Holder, except in the case of willful fraud by such Holder. (iii) Promptly after receipt by an indemnified party under this subsection (e) of notice of the commencement of any action (including any governmental action), such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this subsection (e) deliver to the indemnifying party a written notice of the commencement thereof and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified party (together with all other indemnified parties which may be represented without conflict by one counsel) shall have the right to retain one separate counsel, with the reasonable fees and expenses to be paid by the indemnifying party, if representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential differing interests between such indemnified party and any other party represented by such counsel in such proceeding. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action shall not relieve such indemnifying party of any liability to the indemnified party under this subsection (i) except to the extent such failure is prejudicial to the indemnifying party's ability to defend such action and the omission so to deliver written notice to the indemnifying party will not relieve it of any liability that it -64-

may have to any indemnified party otherwise than under this subsection (i). The indemnifying party shall not consent to entry of any judgment or enter into any settlement unless (i) there is no finding or admission of any violation of any rights of any person and no effect on any other claims that may be made against the indemnified party, and (ii) the sole relief provided is monetary damages that are paid in full by the indemnifying party. (iv) If the indemnification provided for in this subsection (i) is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any Registration Loss referred to therein, then the indemnifying party, in lieu of indemnifying such indemnified party hereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such Registration Loss in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other in connection with the statements or omissions that resulted in such Registration Loss as well as any other relevant equitable considerations; provided, that, in no event shall the aggregate liability of any Holder under this subsection (i)(iv), and Section 5.17(i)(ii) exceed the net proceeds from the offering received by such Holder, except in the case of willful fraud by such Holder. The relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties' relative intent, knowledge, access to information, and opportunity to correct or prevent such statement or omission. Notwithstanding the foregoing, to the extent that the provisions on indemnification and contribution contained in the underwriting agreement entered into in connection with the underwritten public offering are in conflict with the foregoing provisions, the provisions in the underwriting agreement shall control. The obligations of Buyer and Holders under this subsection (i) shall survive the completion of any offering of Registrable Securities in a Registration Statement under this Section 5.17, and otherwise. (j) RESTRICTIONS ON TRANSFERABILITY. Unless covered by an effective Registration Statement, the Buyer Common Stock and any other securities issued in respect of such stock upon any stock split, stock dividend, recapitalization, merger, or similar event, shall not be sold, assigned, transferred or pledged except upon the conditions specified in this Agreement, which conditions are intended to ensure compliance with the provisions of the Securities Act. Each Holder will cause any proposed purchaser, assignee, transferee, or pledgee of any such shares held by the Holder or transferor to agree to take and hold such securities subject to the restrictions and upon the conditions specified in this Agreement. (k) RESTRICTIVE LEGEND. Each certificate representing the Registrable Securities, or any other securities issued in respect of such stock upon any stock split, stock dividend, recapitalization, merger, or similar event, shall (unless otherwise permitted by the provisions of subsection (l) below) be stamped or otherwise imprinted with legends in substantially the following form (in addition to any legends required by agreement or by applicable state securities laws): THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"). SUCH SECURITIES MAY NOT BE TRANSFERRED UNLESS A REGISTRATION -65-

STATEMENT UNDER THE ACT IS IN EFFECT AS TO SUCH TRANSFER OR IN THE OPINION OF COUNSEL FOR THE COMPANY, SUCH TRANSFER MAY BE MADE PURSUANT TO RULE 144, AND, IF APPLICABLE, RULE 145 OR REGISTRATION UNDER THE ACT IS OTHERWISE UNNECESSARY IN ORDER FOR SUCH TRANSFER TO COMPLY WITH THE ACT. Each Holder consents to Buyer making a notation on its records and giving stop transfer instructions to any transfer agent of its capital stock in order to implement the restrictions on transfer established in this Agreement. (l) NOTICE OF PROPOSED TRANSFERS. No sale, assignment, transfer or pledge of Registrable Securities shall be made by any holder thereof to any person unless such person shall first agree in writing to be bound by the restrictions of this Agreement. Prior to any proposed sale, assignment, transfer or pledge of any Registrable Securities, unless there is in effect a Registration Statement under the Securities Act covering the proposed transfer, the holder thereof shall give written notice to Buyer of such holder's intention to effect such transfer, sale, assignment or pledge. Each such notice shall describe the manner and circumstances of the proposed transfer, sale, assignment or pledge in sufficient detail, and, if requested by Buyer, the holder shall also provide, at such holder's expense, either (i) a written opinion of legal counsel who shall be, and whose legal opinion shall be, reasonably satisfactory to Buyer addressed to Buyer, to the effect that the proposed transfer of the Registrable Securities may be effected without registration under the Securities Act, or (ii) a "no action" letter from the SEC to the effect that the transfer of such securities without registration will not result in a recommendation by the staff of the SEC that action be taken with respect thereto, whereupon the holder of such Registrable Securities shall be entitled to transfer such Registrable Securities in accordance with the terms of the notice delivered by the holder to Buyer. Each certificate evidencing the Registrable Securities transferred as above provided shall bear the appropriate restrictive legend set forth in subsection (k) above, except that such certificate shall not bear such restrictive legend if in the opinion of counsel for such holder reasonably acceptable to Buyer such legend is not required in order to establish compliance with any provision of the Securities Act. (m) CURRENT PUBLIC INFORMATION. Buyer covenants that it will file any reports required to be filed by it under the Securities Act and Exchange Act so as to enable Holders holding Buyer Common Stock issued to them hereunder to sell such Buyer Common Stock without registration under the Securities Act within the limitation of the exemptions provided by (a) Rules 144, 144A and 145 under the Securities Act, as each may be amended from time to time, or (b) any similar rule or rules hereafter adopted by the SEC, so long as the exemptions provided for in such Rules would otherwise be available to such Holders at such time. Upon the request of any such Holder, Buyer shall promptly deliver to such Holder a written statement as to whether it has complied with such requirements. Notwithstanding anything in this Agreement to the contrary, (i) the remedy of a Holder for any breach of this paragraph (m) shall be limited to the dollar amount of the Buyer Common Stock that could not be sold or which a Holder was delayed in selling as a result of such breach valued as of the dates and according to the procedures set forth in Article 1 with respect to such shares of Buyer Common Stock, and (ii) no Holder may issue an Officer's Certificate or otherwise assert a breach or make a claim with respect to this paragraph (m) unless such Holder delivers written notice of such breach or claim to Buyer -66-

within thirty (30) days after the date such Holder was first unable to sell its shares of Buyer Common Stock pursuant the exemptions provided by Rules 144, 144A and 145 under the Securities Act, as each may be amended from time to time, as a result of a breach of this paragraph (m). 5.18 DELIVERY OF FINANCIAL STATEMENTS. Commencing with the first fiscal month (or portion thereof) of the Company after the Closing and terminating with the last completed month of the Company occurring prior to the date the Earn-Out Notice is delivered, Buyer shall deliver to each Stockholder Representative as soon as practicable, but in any event within 20 days after the end of each such month, the following financial statements of the Company and its Subsidiaries (which shall be consolidated for the Company and its Subsidiaries only and shall not include the consolidated results of Buyer): an unaudited statement of operations for such month and an unaudited balance sheet as of the end of such month. Each Stockholder Representative shall hold in confidence and trust such financial statements and the information contained therein according to the confidentiality provisions of Section 5.5 hereof. 5.19 PAYMENT OF INVESTMENT BANKING FEE. Concurrent with the payment of the Earn-Out Amount pursuant to the provisions of Section 1.4 hereof, Buyer agrees to pay a cash amount equal to the Investment Banking Fee directly to Bear, Stearns & Co. Inc. in accordance with instructions provided to Buyer by Bear, Stearns & Co., Inc. Such Investment Banking Fee shall reduce the amount of the Earn-Out Amount Buyer is obligated to pay hereunder on a dollar for dollar basis. ARTICLE VI CONDUCT PRIOR TO THE EFFECTIVE TIME 6.1 CONDUCT OF BUSINESS OF THE COMPANY. During the period from the date of this Agreement and continuing until the earlier of the termination of this Agreement or the Effective Time, the Company agrees to conduct its business, except to the extent that Buyer shall otherwise consent in writing, in the usual, regular and ordinary course in substantially the same manner as heretofore conducted, to pay the debts and Taxes of the Company when due (subject to Buyer's right pursuant to Section 6.1(e) to review and approve the filing of any Tax Returns), to pay or perform other obligations when due, and, to the extent consistent with such ordinary course conduct of its business, to preserve intact the present business organizations of the Company, to use reasonable efforts to keep available the services of the present officers and key employees of the Company and to use reasonable efforts to preserve the relationships of the Company with customers, suppliers, distributors, licensors, licensees, and others having business dealings with them.

Except as expressly provided in this Article VIII, the Indemnity Escrow Fund shall be the sole and exclusive source to compensate the Buyer Indemnified Parties for any claims by such parties for any Losses suffered or incurred by them and for which they are entitled to recovery under this ARTICLE VIII. The Escrow Agent may execute this Agreement following the date hereof but prior to the Closing, and such -78-

subsequent execution, if so executed after the date hereof, shall not affect the binding nature of this Agreement as of the date hereof between the other signatories hereto. (b) INDEMNITY ESCROW PERIOD; DISTRIBUTION UPON TERMINATION OF INDEMNITY ESCROW PERIODS. (i) INDEMNITY ESCROW. Subject to the following requirements, the Indemnity Escrow Fund shall be in existence during the period (the "INDEMNITY ESCROW PERIOD") commencing upon receipt by the Escrow Agent of the Indemnity Escrow Fund and shall terminate upon the earlier to occur of (A) 5:00 p.m., local time at Buyer's headquarters, on the date thirty (30) days after the Survival Date (as such date is certified in writing by the Buyer to the Escrow Agent), and (B) the date when the last portion of the Indemnity Escrow Fund then held by the Escrow Agent is distributed in accordance with this Section 8.3 (such date, the "INDEMNITY ESCROW TERMINATION DATE").

The parties hereto understand that, in the event properly executed Forms W-9 (Forms W-8 in the case of non-U.S. persons) are not provided to the Escrow Agent, the Internal Revenue Code, as amended from time to time, may require withholding of a portion of any distributions from the Indemnity Escrow Fund.

(c) PROTECTION OF INDEMNITY ESCROW FUND. The Escrow Agent shall hold and safeguard the Indemnity Escrow Fund during the Indemnity Escrow Period, and shall hold and dispose of the Indemnity Escrow Fund only in accordance with the terms of this ARTICLE VIII.

(i) Upon receipt by the Escrow Agent at any time on or before the Indemnity Escrow Termination Date of an Officer's Certificate (as defined below) from Buyer, the Escrow Agent shall, subject to the provisions of this Section 8.3, deliver to Buyer, as promptly as practicable, funds held in the Indemnity Escrow Fund equal to the Losses specified in such Officer's Certificate (to the extent available). Upon receipt by Buyer at any time on or before the Survival Date of an Officer's Certificate from the Onex Stockholder Representative or the Non-Onex Stockholder Representative Committee, Buyer shall, subject to the provisions of this Section 8.3, deliver to the notifying Stockholder Representative, as promptly as practicable, cash equal to the Losses specified in such Officer's Certificate. At the time of delivery of any Officer's Certificate by Buyer to the Escrow Agent, Buyer shall deliver a duplicate copy of such Officer's Certificate to each of the Onex Stockholder Representative and the members of the Non-Onex Stockholder Representative Committee. At the time of delivery of any Officer's Certificate by a Stockholder Representative to Buyer, such Stockholder Representative shall deliver a duplicate copy of such Officer's Certificate to such other Stockholder Representative (or Stockholder Representative Committee, as appropriate). For the purposes hereof, -80-

"OFFICER'S CERTIFICATE" shall mean a certificate signed by a duly authorized officer(s) of the applicable Indemnified Party (1) stating that an Indemnified Party has paid, sustained, incurred, or properly accrued, or reasonably anticipates in good faith that it will have to pay, sustain, incur, or accrue Losses, and (2) specifying in reasonable detail the individual items of Losses included in the amount so stated, the date each such item was paid, sustained, incurred, or properly accrued, or the basis for such anticipated liability, and the nature of the misrepresentation, breach of warranty or covenant, as applicable, to which such Loss is related. (ii) If either the Onex Stockholder Representative or the Non-Onex Stockholder Representative Committee, as applicable, fails to object in writing within the 30-day period after delivery by Buyer of an Officer's Certificate to such Stockholder Representative, such failure to so object shall be an irrevocable acknowledgment by the non-objecting Stockholder Representative and the Indemnifying Stockholders represented by such Stockholder Representative that the Buyer Indemnified Parties are entitled to the full amount of the claim for Losses set forth in such Officer's Certificate allocable to such Indemnifying Stockholders. If Buyer does not object in writing within the 30-day period after delivery by the Onex Stockholder Representative or the Non-Onex Stockholder Representative Committee, as applicable, of an Officer's Certificate to Buyer, such failure to so object shall be an irrevocable acknowledgement by Buyer that the applicable Stockholder Indemnified Parties are entitled to the full amount of the claim for Losses set forth in such Officer's Certificate. (iii) In the event that a distribution from the Indemnity Escrow Fund is made to Buyer on account of any such misrepresentation or breach by a Selling Stockholder for which it is severally liable as provided above, the applicable Selling Stockholder shall at the time of such distribution repay to the Indemnifying Stockholders (other than itself if it is an Indemnifying Stockholder) the amount of such distribution, with such payment to be distributed among the other Indemnifying Stockholders on a pro rata basis based on their respective Indemnity Pro Rata Portions (without taking into account the Indemnity Pro Rata Portion of the paying Selling Stockholder). (IV) TAX INDEMNIFICATION. The parties hereto agree, jointly and severally, to indemnify and hold the Escrow Agent harmless from any liability or obligations on account of taxes, assessments, additions for late payment, interest, penalties, expenses and other governmental charges that may be assessed or asserted against the Escrow Agent in connection with or relating to any payment made or other activities performed under the terms of this Agreement (other than taxes assessed against the income of the Escrow Agent derived from its fees), including without limitation any liability for the withholding or deduction of (or failure to withhold or deduct) the same, and any liability for failure to obtain proper certifications or to report properly to governmental authorities in connection with this Agreement, including costs and expenses (including reasonable legal fees and expenses), interest and penalties. The foregoing indemnification and agreement to hold harmless shall survive the termination of this Agreement. (e) OBJECTIONS TO CLAIMS. (i) For a period of thirty (30) days after delivery of an Officer's Certificate to the Onex Stockholder Representative, the members of the Non-Onex Stockholder Representative Committee and Escrow Agent, the Escrow Agent shall not distribute any portion of the Indemnity -81-

Escrow Fund unless the Escrow Agent shall have received written authorization from the Onex Stockholder Representative and the Non-Onex Stockholder Representative Committee to make such distribution. After the expiration of such thirty (30) day period, the Escrow Agent shall deliver cash from the Indemnity Escrow Fund equal to the amount of Losses claimed in such Officer's Certificate, provided that no such payment or delivery may be made if either Stockholder Representative shall object in a written statement to the claim made in such Officer's Certificate (an "OBJECTION NOTICE"), and such Objection Notice shall have been delivered to the Escrow Agent prior to the expiration of such thirty (30) day period. The amount objected to by a Stockholder Representative in an Objection Notice is referred to as a "DISPUTED AMOUNT." (ii) If Buyer objects to the claim made in any Officer's Certificate delivered by either the Onex Stockholder Representative or the Non-Onex Stockholder Representative Committee (as the case may be), it shall deliver a written statement of such objection (a "BUYER OBJECTION NOTICE") to the applicable Stockholder Representative within thirty (30) days after receipt of such Officer's Certificate by Buyer. Buyer shall not be obligated to deliver payment in respect of such Losses allocable to the Indemnifying Stockholders represented by such notifying Stockholder Representative until resolution of such disputed claim in accordance with Section 8.3(f) below. (f) RESOLUTION OF CONFLICTS; ARBITRATION. (i) In case either the Onex Stockholder Representative or the Non-Onex Stockholder Representative Committee delivers an Objection Notice or Buyer delivers a Buyer Objection Notice, the objecting Stockholder Representative(s) and Buyer shall attempt in good faith, for a period of at least thirty (30) days, to agree upon the rights of the respective parties with respect to each of such claims and the amount of Losses. If the Stockholder Representative(s) and Buyer should so agree, a memorandum setting forth such agreement shall be prepared and signed by both parties and, in the case of a claim against the Indemnity Escrow Fund, shall be furnished to the Escrow Agent. The Escrow Agent shall be entitled to rely on any such memorandum and shall make distributions from the Indemnity Escrow Fund in accordance with the terms thereof. (ii) If no such agreement can be reached after good faith negotiation and after thirty (30) days from the date of the delivery of an Objection Notice or a Buyer Objection Notice, either Buyer or the applicable Stockholder Representative may demand arbitration of the matter unless the amount of the Loss is at issue in a pending Third Party Claim, in which event arbitration shall not be commenced until either such amount is finally determined pursuant to a final, non-appealable order, judgment or decree (as certified in writing to the Escrow Agent by the applicable party), or both parties agree to arbitration, and in either such event the matter shall be settled by binding arbitration conducted by one arbitrator mutually selected by Buyer and such Stockholder Representative. In the event that, within thirty (30) days after submission of any dispute to arbitration, Buyer and such Stockholder Representative cannot mutually agree on one arbitrator, then, within fifteen (15) days after the end of such thirty (30) day period, Buyer and the Stockholder Representative shall each select one neutral arbitrator. The two arbitrators so selected shall select a third neutral arbitrator. If either such Stockholder Representative or the Buyer fails to select an arbitrator during this fifteen (15) day period, -82-

then the parties agree that the arbitration will be conducted by the one neutral arbitrator selected by the other party. (iii) Any such arbitration shall be held in New York City, New York, under the Commercial Arbitration Rules then in effect of the American Arbitration Association. All reasonable fees and expenses relating to the arbitration, including, without limitation, the respective expenses of each party (including, without limitation, reasonable attorneys' fees and costs of investigation), the fees of each arbitrator and the administrative fee of the American Arbitration Association shall be borne by the non-prevailing party, as determined by the arbitrator(s). The arbitrator or arbitrators, as the case may be, shall set a limited time period and establish procedures designed to reduce the cost and time for discovery while allowing the parties an opportunity, adequate in the sole judgment of the arbitrator or majority of the three arbitrators, as the case may be, to discover relevant information from the opposing parties solely to the extent related to the subject matter of the dispute. The arbitrator, or a majority of the three arbitrators, as the case may be, shall rule upon motions to compel or limit discovery and shall have the authority to impose sanctions to the same extent as a competent court of law or equity, should the arbitrators or a majority of the three arbitrators, as the case may be, determine that discovery was sought without reasonable justification or that discovery was refused or objected to without reasonable justification. The decision of the arbitrator or a majority of the three arbitrators, as the case may be, as to the validity and amount of any claim in such Officer's Certificate shall be final, binding, and conclusive upon the parties to this Agreement and shall not be appealable. Such decision shall be written and shall be supported by written findings of fact and conclusions which shall set forth the award, judgment, decree or order awarded by the arbitrator(s). In case of a claim by Buyer against the Indemnity Escrow Fund, the Escrow Agent shall be entitled to rely on, and make distributions from the Indemnity Escrow Fund in accordance with, the terms of such award, judgment, decree or order, as applicable. Within thirty (30) days of a decision of the arbitrator(s) requiring payment by one party to another, such party (or, in case of a claim by Buyer against the Indemnity Escrow Fund, the Escrow Agent) shall make the payment to such other party in accordance with the terms of this ARTICLE VIII. (iv) Judgment upon any award rendered by the arbitrator(s) may be entered in any court having jurisdiction. The foregoing arbitration provision shall apply to any dispute among the parties under this ARTICLE VIII or Section 1.4, whether relating to claims upon the Indemnity Escrow Fund or to the other indemnification obligations set forth in this ARTICLE VIII or disputes relating to the Earn-Out Payment. (g) THIRD-PARTY CLAIMS. (i) Promptly after receipt by an Indemnified Party of notice of the commencement of a third party claim (a "THIRD PARTY CLAIM") against it, such Indemnified Party shall, if a claim in respect thereof is to be made against an indemnifying party under this ARTICLE VIII, give written notice to the indemnifying party and, in case of a claim against the Indemnity Escrow Fund, the Escrow Agent, of the commencement thereof, but the failure to so notify the indemnifying party shall not relieve it of any liability that it may have to any Indemnified Party except to the extent the indemnifying party demonstrates that the defense of such action is prejudiced thereby. In case any such Third Party Claim shall be brought against an Indemnified Party and it shall give notice to the -83-

indemnifying party (and the Escrow Agent, if applicable) of the commencement thereof, then the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish (unless (i) an indemnifying party is also a party to such Third Party Claim and the Indemnified Party reasonably concludes, based on the advice of counsel, that joint representation would create a conflict of interest, (ii) the Third Party Claim asserts infringement of intellectual property rights) to assume the defense thereof with counsel reasonably satisfactory to such Indemnified Party and, after notice from such indemnifying party to such Indemnified Party of its election so to assume the defense thereof, such indemnifying party shall not be liable to such Indemnified Party under this ARTICLE VIII for any fees of other counsel or any other expenses with respect to the defense of such Third Party Claim, in each case, subsequently incurred by such Indemnified Party in connection with the defense thereof unless the indemnifying party shall have failed, after notice by the Indemnified Party to the indemnifying party, to defend such claim. An Indemnified Party shall, at its own expense (except as provided for in the preceding sentence), have the right to employ separate counsel in any such action or claim and to participate in, but not control, the defense thereof. If an indemnifying party assumes the defense of such Third Party Claim, (A) no compromise or settlement thereof may be effected by the indemnifying party without the Indemnified Party's consent (not to be unreasonably withheld), unless (1) there is no finding or admission of any violation of law or any violation of the rights of any Person and no effect on any other claims that may be made against the Indemnified Party and (2) the sole relief provided is monetary damages that are paid in full by the indemnifying party and (B) the indemnifying party shall have no liability with respect to any compromise or settlement thereof effected without its consent. If notice is given to an indemnifying party of the commencement of any Third Party Claim and it does not, within thirty (30) Business Days after the Indemnified Party's notice is provided, give notice to the Indemnified Party of its election to assume the defense thereof, the indemnifying party shall only be bound by any determination made in such Third Party Claim or any compromise or settlement thereof effected by the Indemnified Party if consented to by the indemnifying party (which consent shall not be unreasonably withheld), subject in any such case to the limitations set forth in Section 8.5. Notwithstanding anything in this Section 8.3(g) to the contrary, in no event may any Selling Stockholder (other than a Stockholder Representative) participate in or assume the defense of any Third Party Claim as an indemnifying party pursuant to this Section 8.3(g); instead, the right to so participate in or assume the defense of any Third Party Claim pursuant to this Section 8.3(g) shall belong to the Stockholder Representative(s) representing such Selling Stockholder(s). (h) ESCROW AGENT'S DUTIES. (i) The Escrow Agent shall be obligated only for the performance of such duties as are specifically set forth in this ARTICLE VIII, and as set forth in any additional written escrow instructions which the Escrow Agent may receive after the date of this Agreement which are signed by a duly authorized officer of Buyer and the Onex Stockholder Representative and the Non-Onex Stockholder Representative Committee which are not inconsistent with the terms of this ARTICLE VIII, and may rely and shall be protected in relying or refraining from acting on any instrument reasonably believed to be genuine and to have been signed or presented by the proper party or parties.

(iii) The Escrow Agent shall not be liable in any respect on account of the identity, authority or rights of the parties executing or delivering or purporting to execute or deliver this Agreement or any documents or papers deposited or called for hereunder. (iv) The Escrow Agent shall not be liable for the expiration of any rights under any statute of limitations with respect to this Agreement or any documents deposited with the Escrow Agent. (v) The Escrow Agent's duties hereunder are ministerial, and shall not be construed as fiduciary, and in no event shall the Escrow Agent be liable for indirect, punitive, or consequential damages, including damages arising from a loss arising from the liquidation of investments to pay a claim hereunder. In performing any duties under this Agreement, the Escrow Agent shall not be liable to any party for damages, losses, or expenses, except as a result of gross negligence or willful misconduct on the part of the Escrow Agent. The Escrow Agent shall not incur any such liability for (A) any act or failure to act made or omitted in good faith, or (B) any action taken or omitted in reliance upon any instrument, including any written statement or affidavit provided for in this Agreement that the Escrow Agent shall in good faith believe to be genuine, nor will the Escrow Agent be liable or responsible for forgeries, fraud, impersonations, or determining the scope of any representative authority. In addition, the Escrow Agent may consult with legal counsel in connection with performing the Escrow Agent's duties under this Agreement and shall be fully protected in any act taken, suffered, or permitted by him/her in good faith in accordance with the advice of counsel. The Escrow Agent is not responsible for determining and verifying the authority of any person acting or purporting to act on behalf of any party to this Agreement. (vi) If any controversy arises between the parties to this Agreement, or with any other party, concerning the subject matter of this Agreement, its terms or conditions, the Escrow Agent will not be required to determine the controversy or to take any action regarding it. The Escrow Agent may hold all documents and the Indemnity Escrow Fund and may wait for settlement of any such controversy by final appropriate legal proceedings or other means as, in the Escrow Agent's discretion, may be required, subject to the terms of this Agreement. In such event, the Escrow Agent will not be liable for damages. Furthermore, the Escrow Agent may at its option, file an action of interpleader requiring the parties to answer and litigate any claims and rights among themselves. The Escrow Agent is authorized to deposit with the clerk of the court all documents and the Indemnity Escrow Fund held in escrow. All costs, expenses, charges and reasonable attorney fees incurred by the Escrow Agent due to the interpleader action (the "AGENT INTERPLEADER EXPENSES") shall be paid by the parties as follows: fifty percent (50%) to be paid by Buyer and fifty percent (50%) to be paid out of (and only to the extent -93-

of) the Indemnity Escrow Fund, with any shortfall due to the Indemnity Escrow Fund being exhausted paid for by Buyer. Upon initiating such action, the Escrow Agent shall be fully released and discharged of and from all obligations and liability imposed by the terms of this Agreement. (vii) The parties and their respective successors and assigns agree to indemnify (as provided herein) and hold the Escrow Agent harmless against any and all losses, claims, damages, liabilities, and expenses, including reasonable costs of investigation, counsel fees, including allocated costs of in-house counsel and disbursements that may be imposed on the Escrow Agent or incurred by the Escrow Agent in connection with the performance of his/her duties under this Agreement, including but not limited to any litigation arising from this Agreement or involving its subject matter, other than those arising out of the gross negligence or willful misconduct of the Escrow Agent (the "AGENT INDEMNIFICATION EXPENSES") as follows: fifty percent (50%) to be paid by Buyer and fifty percent (50%) to be paid out of (and only to the extent of) the Indemnity Escrow Fund, with any shortfall due to the Indemnity Escrow Fund being exhausted paid for by Buyer. This section shall survive the termination of this Agreement. (viii) The Escrow Agent may resign at any time upon giving at least thirty (30) days written notice to the Buyer, the Onex Stockholder Representative and the members of the Non-Onex Stockholder Representative Committee; provided, however, that no such resignation shall become effective until the appointment of a successor escrow agent which shall be accomplished as follows: Buyer, the Onex Stockholder Representative and the Non-Onex Stockholder Representative Committee shall use their best efforts to mutually agree on a successor escrow agent within thirty (30) days after receiving such notice. If the parties fail to agree upon a successor escrow agent within such time, the Escrow Agent shall have the right to appoint a successor escrow agent authorized to do business in the State of New York or, failing that, to apply to a court of competent jurisdiction to appoint a successor escrow agent. The successor escrow agent shall execute and deliver an instrument accepting such appointment and it shall, without further acts, be vested with all the estates, properties, rights, powers, and duties of the predecessor escrow agent as if originally named as escrow agent. Upon appointment of a successor escrow agent, the Escrow Agent shall be discharged from any further duties and liability under this Agreement. (i) FEES. All fees of the Escrow Agent for performance of its duties hereunder shall be paid by Buyer in accordance with the standard fee schedule of the Escrow Agent. It is understood that the fees and usual charges agreed upon for services of the Escrow Agent shall be considered compensation for ordinary services as contemplated by this Agreement. In the event that the conditions of this Agreement are not promptly fulfilled, or if the Escrow Agent renders any service not provided for in this Agreement but that has been requested by an officer of Buyer, or if the parties request a substantial modification of the terms of the Agreement, or if any controversy arises, or if the Escrow Agent is made a party to, or intervenes in, any litigation pertaining to the Indemnity Escrow Fund or its subject matter, the Escrow Agent shall be reasonably compensated for such extraordinary services and reimbursed for all costs, attorney's fees, including allocated costs of in-house counsel, and expenses occasioned by such default, delay, controversy or litigation. -94-

Notwithstanding the foregoing, an Indemnified Party shall be entitled to recover for, and the Threshold Amount shall not apply as a threshold to, any and all claims or payments made with respect to (i) Losses involving any intentional misrepresentations or fraud or (ii) Excess Amounts.

Notwithstanding the foregoing, the Stockholder Indemnified Parties may recover Losses arising, directly or indirectly, as a result of a breach or violation by Buyer of the covenants -98-

contained in Section 1.4(h) above, up to an aggregate amount equal to $55,000,000 multiplied by the aggregate Earn-Out Percentage reflected on the applicable Consideration Schedule applicable to all Selling Stockholders and Surrendering Optionees. (d) Notwithstanding anything to the contrary contained herein, except as set forth in Section 8.5(f) hereof, the maximum amount of Losses that the Buyer Indemnified Parties may recover from any Selling Stockholder pursuant to this ARTICLE VIII for breach by such Selling Stockholder of any of its representations and warranties set forth in ARTICLE III hereof shall be limited to the total amount of Consideration paid to such Selling Stockholder hereunder (and the Indemnity Escrow Fund shall not be the exclusive remedy). The value of shares of Buyer Common Stock received by any such Selling Stockholder, if any, shall be valued as of the dates and according to the procedures set forth in Article 1 with respect to such shares of Buyer Common Stock. With respect to Losses arising out of the breach of representations and warranties made by a Selling Stockholder or in any covenant or other agreement made by such Selling Stockholder, the liability to the Buyer Indemnified Parties under this ARTICLE VIII shall be the several liability of the applicable Selling Stockholder who made such misrepresentation or breached such warranty, representation, covenant or other agreement, and the other Selling Stockholders shall have no liability in respect thereof.

In no event shall this provision modify the timing of payment obligations of Buyer pursuant to Section 1.4. (f) Any Losses a Buyer Indemnified Party may recover from any Indemnifying Stockholder or any Selling Stockholder shall first be paid out of the Indemnity Escrow Fund. Notwithstanding anything to the contrary set forth in this Agreement, nothing in this Agreement shall limit the liability of any party (and the Indemnity Escrow Fund shall not be the exclusive remedy) in respect of Losses arising out of any fraud or any willful breaches of representations and warranties or covenants on the part of such party. (g) The amount of any Losses for which indemnification is provided under this ARTICLE VIII shall be reduced by any insurance proceeds related thereto actually received by the Indemnified Party or any of its Affiliates.

The exact number of Shares to be purchased shall be determined immediately prior to the Closing. If UIL sells all of its Shares to the Purchaser, then the Purchaser shall purchase a total of Fifty-four Million One Hundred Twenty-eight Thousand (54,128,000) Shares (representing 51% of all of the Shares of the Company held by the Sellers collectively and equivalent to 41.64% of the issued and outstanding Shares of the Company) from the Sellers at the Closing; otherwise, if UIL does not sell all of its -1-

(f) The Company Accountants shall have thirty (30) days to calculate and certify the Exercise Earn-out after the date one year after the Exercise Date.

(a) If the Closing occurs, in order for the Sellers to have any liability (for indemnification or otherwise) with respect to any representation or warranty, or covenant or obligation to be performed and complied with prior to the Closing Date (excepting those in Sections C.3, C.4, C.7 and C.14), the Purchaser must notify the Company of a claim specifying the factual basis of that claim in reasonable detail to the extent then known by the Purchaser on or before the following limitations periods (each, a "Time Limitation Period"): -8-

(i) With respect to claims under Section 6.2(a), not later than one (1) year after the Closing Date; (ii) With respect to claims under Section 6.2(b), not later than last day of that a Governmental Body may pursue the Company for such matters under applicable Legal Requirements; (iii) With respect to claims under Section 6.2(c), not later than two (2) years after the Closing Date; and (iv) With respect to claims under Section 6.2(d), not later than six (6) months after the Closing Date.

SECTION 6.5 LIMITATION ON AMOUNT; ESCROW OF PORTION OF REMAINING SHARES. (a) The indemnifying party will have no liability (for indemnification or otherwise) with respect to the matters described in this Article VI until the total of all Damages with respect to such matters exceeds NT$15,000,000 (the "Indemnification Basket"), and then only for the amount by which such Damages exceed the Indemnification Basket. However, the Indemnification Basket will not apply to (i) any Breach of the indemnifying persons' representations and warranties of which either the indemnifying person had Actual Knowledge at any time prior to the date on which such representation or warranty is made, (ii) any intentional Breach by the indemnifying party of any covenant or obligation, or (iii) a breach of the representations and warranties contained in Section C.12(e), and in such cases, the party seeking indemnification may seek indemnification without satisfying the Indemnification Basket. (b) In no event shall the indemnifying party's aggregate total liability (for indemnification or otherwise) under this Section 6 exceed US$7 million (the "Indemnification Limit"). Each Seller agrees to allow the Purchaser to deposit a number of Share Certificates representing his/her/its Remaining Shares equal to such Seller's pro rata portion of the total number of Shares equal to the Indemnification Limit (calculated using the Purchase Price as defined in Section 1.3 hereof as the value of such Remaining Shares) into an escrow account designated by the Purchaser and agreed by the Sellers pursuant to Section F6 to be used to pay any Damages to which the Indemnified Persons may be entitled under this Article 6. Such Share Certificates shall remain in the escrow account until the date two (2) years from the Closing Date. In the event that the Purchaser exercises the Option prior to such date, the Sellers agree that the Purchaser -9-

may withhold from the Exercise Price an amount equal to the Indemnification Limit to be deposited into an escrow account until the date two (2) years from the Closing Date. In the event that any Damages are to be deducted from the Remaining Shares or the withheld Exercise Price, they shall be deducted from each Seller pro rata (and in the case of Share Certificates, as close to pro rata as reasonably possible). (c) In the event that the Purchaser does not exercise the Option within the Option Period, the Purchaser shall cause the Escrow Agent to release from escrow all the Share Certificates representing the Remaining Shares back to the Sellers, who may then cancel their endorsements for transfer on the back of each Share Certificate; provided, however, that any Share Certificates representing Remaining Shares held in escrow for purpose of securing the Indemnification Limit pursuant to Section 6.5(b) shall remain in escrow subject to the provisions of Section 6.5(b) until the date two (2) years from the Closing Date. (d) After the date two (2) years from the Closing Date, if there are any Share Certificates remaining in said escrow account (or any portion of the withheld Exercise Price remaining in said escrow account), they will be returned to the Sellers; provided, however, that if the date two (2) years from the Closing Date has past and there is still an amount of Damages that is the subject of an indemnification claim that has not yet been conclusively resolved, none of the Share Certificates (or no portion of the withheld Exercise Price) shall be returned until the Purchaser is satisfied that all indemnification claims have been paid and any disputes with respect thereto have been conclusively resolved. SECTION 6.6 PROCEDURE FOR INDEMNIFICATION-THIRD PARTY CLAIMS. Subject to the provisions of Sections 6.4 and 6.5 hereof: (a) Promptly after receipt by an indemnified party under Section 6.2 or 6.3 of notice of the commencement of any Proceeding against it by a third party, such indemnified party will, if a claim is to be made against an indemnifying party under such Section, give notice to the indemnifying party of the commencement of such claim, but the failure to notify the indemnifying party will not relieve the indemnifying party of any liability that it may have to any indemnified party, except to the extent that the indemnifying party demonstrates that the defense of such action is prejudiced by the indemnifying party's failure to give such notice; provided, however, that if the indemnified party intentionally failed to give such notice, the indemnifying party will be deemed to have been prejudiced by the amount of attorneys' fees incurred with respect thereto through the date notice is received by the indemnifying party and the indemnifying party will not be required to indemnify the indemnified party for such attorneys' fees. (b) If any Proceeding referred to in Section 6.6(a) is brought against an indemnified party and it gives notice to the indemnifying party of the commencement of such Proceeding, the indemnifying party will be entitled to participate in such Proceeding and, to the extent that it wishes (unless (i) the indemnifying party is also a party to such Proceeding and the indemnified party determines in good faith that joint representation would be inappropriate, or (ii) the indemnifying party fails to provide reasonable assurance to the indemnified party of its financial capacity to defend such Proceeding and provide indemnification with respect to such Proceeding), to assume the defense of such Proceeding with counsel reasonably satisfactory to the indemnified party and, after notice from the indemnifying party to the indemnified party of its election to assume -10-

the defense of such Proceeding, the indemnifying party will not, as long as it diligently conducts such defense, be liable to the indemnified party under this Article VI for any fees of other counsel or any other expenses with respect to the defense of such Proceeding, in each case subsequently incurred by the indemnified party in connection with the defense of such Proceeding, other than reasonable costs of investigation and monitoring of defense of such Proceeding. If the indemnifying party assumes the defense of a Proceeding, (i) it will be conclusively established for purposes of this Agreement that the claims made in that Proceeding are within the scope of and subject to indemnification; (ii) no compromise or settlement of such claims may be effected by the indemnifying party without the indemnified party's consent unless (A) there is no finding or admission of any violation of Legal Requirements or any violation of the rights of any Person and no effect on any other claims that may be made against the indemnified party, and (B) the sole relief provided is monetary damages that are paid in full by the indemnifying party; and (iii) the indemnified party will have no liability with respect to any compromise or settlement of such claims effected without its consent. If notice is given to an indemnifying party of the commencement of any Proceeding and the indemnifying party does not, within ten (10) days after the indemnified party's notice is given, give notice to the indemnified party of its election to assume the defense of such Proceeding, the indemnifying party will be bound by any determination made in such Proceeding or any compromise or settlement effected by the indemnified party. (c) Notwithstanding the foregoing, if an indemnified party determines in good faith that there is a reasonable probability that a Proceeding may adversely affect it or its Affiliates other than as a result of monetary damages for which it would be entitled to indemnification under this Agreement, the indemnified party may, by notice to the indemnifying party, assume the exclusive right to defend, compromise, or settle such Proceeding, but the indemnifying party will not be bound by any determination of a Proceeding so defended or any compromise or settlement effected without its consent (which may not be unreasonably withheld). (d) The Sellers hereby consent to the non-exclusive jurisdiction of any court in which a Proceeding is brought against any Indemnified Person for purposes of any claim that an Indemnified Person may have under this Agreement with respect to such Proceeding or the matters alleged therein, and agrees that process may be served on it with respect to such a claim anywhere in the world. (e) After such a Proceeding brought by a third party has concluded and one Party seeks to claim indemnification from the other Party, the Party seeking indemnification shall notify the other Party of the claim in writing. After the notice is given, the Parties shall discuss in good faith or otherwise resolve the claim. If after thirty (30) days, the Parties are not able to resolve the claim, either Party may submit the claim for final and binding arbitration pursuant to Section H.5. Where the Purchaser is the Party seeking indemnification, if the Parties reach a resolution or the Purchaser prevails in arbitration, the Purchaser shall be entitled to satisfy its claim for Damages from the Share Certificates representing Remaining Shares (calculated using the Purchase Price as the value of such Remaining Shares), or the withheld Exercise Price, in accordance with Section 6.5 by taking possession of the appropriate number of Share Certificates representing Remaining Shares or cash from the withheld Exercise Price, as the case may be. If the Sellers are the Party seeking indemnification, if the Parties reach a resolution or the Sellers prevail in arbitration, the Sellers shall be entitled to satisfy -11-

their claim for Damages as agreed by the Parties or as decided by the Tribunal, as the case may be. Section 6.7 PROCEDURE FOR INDEMNIFICATION-OTHER CLAIMS. A claim for indemnification for any matter not involving a third-party claim may be asserted by notice to the Party from whom indemnification is sought. The notice must specify the factual basis of the claim in reasonable detail to the extent known by the Party seeking indemnification. After the notice is given, the Parties shall discuss in good faith or otherwise resolve the claim. If after thirty (30) days, the Parties are not able to resolve the claim, either Party may submit the claim for final and binding arbitration pursuant to Section H.5. Where the Purchaser is the Party seeking indemnification, if the Parties reach a resolution or the Purchaser prevails in arbitration, the Purchaser shall be entitled to satisfy its claim for Damages from the Share Certificates representing Remaining Shares (calculated using the Purchase Price as the value of such Remaining Shares), or the withheld Exercise Price, in accordance with Section 6.5 by taking possession of the appropriate number of Share Certificates representing Remaining Shares or cash from the withheld Exercise Price, as the case may be. If the Sellers are the Party seeking indemnification, if the Parties reach a resolution or the Sellers prevail in arbitration, the Sellers shall be entitled to satisfy their claim for Damages as agreed by the Parties or as decided by the Tribunal, as the case may be.

Exhibit 99.1 AMKOR COMPLETES ACQUISITION OF UNITIVE POISED FOR LEADERSHIP IN FLIP CHIP AND WAFER LEVEL PACKAGING CHANDLER, Ariz., Aug. 24 -- Amkor Technology, Inc. (Nasdaq: AMKR) today announced that it has completed the acquisition of North Carolina-based Unitive, Inc. ("Unitive") together with a majority interest in Unitive Semiconductor Taiwan Corporation ("UST") for $48 million, the assumption of approximately $23 million in debt and performance based earn-outs of up to $57 million. At closing, Amkor acquired approximately 60% of UST and approximately 93% of Unitive, the remaining 7% of Unitive to be acquired in a subsequent restructuring already included in the above purchase price. Unitive and UST are among the world's leading providers of wafer level technologies and services for flip chip and wafer level packaging applications. Unitive and UST will operate as subsidiaries of Amkor. With these acquisitions, Amkor gains industry-leading technology for electroplated wafer bumping and turnkey wafer level "chip scale" packaging, together with installed and operationally qualified, high volume 200mm and 300mm electroplated wafer bumping and wafer level packaging manufacturing operations. Amkor made an initial payment of $32 million and will pay the $16 million balance in one year. In addition, Amkor has a call option to acquire the remaining interest of approximately 40% of UST at any time over the next 18 months for NT$611 million, or approximately $18 million. As previously announced, the transaction provides for performance based earn-outs that are estimated at an aggregate of $57 million payable one year from closing, a maximum of $55 million of which is payable in cash or stock at Amkor's discretion and approximately $2 million of which is payable in cash. "We are excited about the growth opportunities in flip chip and wafer level packaging and look forward to integrating Unitive's and UST's technology and production capabilities with those of Amkor," said Oleg Khaykin, Amkor's executive vice president, corporate development. The current Unitive and UST management teams in North Carolina and Taiwan will remain in place. Unitive will continue to focus on development of advanced wafer level processing technologies and will offer turnkey wafer bumping and wafer level packaging services. UST will provide electroplated wafer bumping and, through integration with Amkor's operations, a complete suite of wafer level processing, assembly and test services.
