▇▇▇▇▇▇ Brothers Inc.

▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇▇

▇▇▇▇▇ ▇▇▇▇, ▇▇ ▇▇▇▇▇

Dear Sirs:

ChipPAC, Inc., a Delaware corporation (the “Company”), proposes to issue and sell to ▇▇▇▇▇▇ Brothers Inc. (the “Initial Purchaser”), upon the terms set forth in a purchase agreement dated May 22, 2003 (the “Purchase Agreement”), $125,000,000 aggregate principal amount (plus up to an additional $25,000,000 principal amount) of its 2.50% Convertible Subordinated Notes due 2008, (the “Initial Securities”). The Initial Securities will be convertible into shares of Class A common stock, par value $0.01 per share, of the Company (the “Common Stock”) at the conversion price set forth in the Offering Circular dated May 22, 2003. The Initial Securities will be issued pursuant to an Indenture, dated as of May 28, 2003, (the “Indenture”), among the Company and U.S. Bank National Association, as trustee (the “Trustee”). As an inducement to the Initial Purchaser to enter into the Purchase Agreement, the Company agrees with the Initial Purchaser, for the benefit of (i) the Initial Purchaser and (ii) the holders of the Initial Securities and the Common Stock issuable upon conversion of the Initial Securities (collectively, the “Securities”) from time to time until such time as such Securities have been sold pursuant to a Shelf Registration Statement (as defined below) (each of the forgoing a “Holder” and collectively the “Holders”), as follows:

1. Shelf Registration. (a) The Company shall, at its cost, prepare and, as promptly as practicable (but in no event more than 90 days after the First Closing Date, (as defined in the Purchase Agreement) file with the Securities and Exchange Commission (the “Commission”) and thereafter use its commercially reasonable efforts to cause to be declared effective as soon as practicable a registration statement on an appropriate form under the Securities Act within 180 days of the First Closing Date, (the “Shelf Registration Statement”) relating to the offer and sale of the Transfer Restricted Securities (as defined in Section 5 hereof) by the Holders thereof from time to time in accordance with the methods of distribution set forth in the Shelf Registration Statement and Rule 415 under the Securities Act of 1933 (the “Securities Act”) (hereinafter, the “Shelf Registration”); provided, however, that no Holder (other than the Initial Purchaser) shall be entitled to have the Securities held by it covered by such Shelf Registration Statement unless such Holder agrees in writing to be bound by all the provisions of this Agreement applicable to such Holder.

(b) The Company shall use its commercially reasonable efforts to keep the Shelf Registration Statement continuously effective in order to permit the Prospectus included therein (the “Prospectus”) to be lawfully delivered by the Holders of the relevant Securities, for a period of two years (or for such longer period if extended pursuant to Section 2(h) below) from the first date of the original issuance of the Initial Securities or such shorter period that will terminate when all the Securities covered by the Shelf Registration Statement (i) have been sold pursuant thereto, or have otherwise been disposed of in accordance with the Securities Act, (ii) are eligible to be sold to the public pursuant to Rule 144(k) under the Securities Act or any successor rule thereof, without limitations under clauses (c), (e), (f) and (h) of Rule 144 under the Securities Act or any successor provisions thereof, assuming for this purpose that the Holders thereof are not affiliates of the Company (in any such case, such period being called the “Shelf Registration Period”). The Company shall be deemed not to have used its commercially reasonable efforts to keep

the Shelf Registration Statement effective during the requisite period if it voluntarily takes any action that would result in Holders of Securities covered thereby not being able to offer and sell such Securities during that period, unless such action is (i) required by applicable law or (ii) taken by the Company in good faith upon the occurrence of any event contemplated by Section 2(b)(v) below, and the Company thereafter complies with the requirements of Section 2(h).

(c) Notwithstanding any other provisions of this Agreement to the contrary, the Company shall cause the Shelf Registration Statement and the Prospectus and any amendment or supplement thereto, as of the effective date of the Shelf Registration Statement, amendment or supplement, (i) to comply in all material respects with the applicable requirements of the Securities Act and the rules and regulations of the Commission and (ii) not to contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading.

2. Registration Procedures. In connection with the Shelf Registration contemplated by Section 1 hereof, the following provisions shall apply:

(a) The Company shall (i) furnish to the Initial Purchaser, prior to the filing thereof with the Commission, a copy of the Shelf Registration Statement and each amendment thereof and each supplement, if any, to the Prospectus included therein and, in the event that the Initial Purchaser (with respect to any portion of an unsold allotment from the original offering) is participating in the Shelf Registration Statement, shall use its reasonable best efforts to reflect in each such document, when so filed with the Commission, such comments as such Initial Purchaser reasonably may propose; and (ii) include the names of the Holders who propose to sell Securities pursuant to the Shelf Registration Statement as selling securityholders; provided that the Initial Purchaser and the Holders have complied with Section 2(m).

(b) The Company shall give written notice to the Initial Purchaser and the Holders of the Securities included within the coverage of the Shelf Registration Statement (which notice pursuant to clauses (ii)-(v) hereof shall be accompanied by an instruction to suspend the use of the Prospectus until the requisite changes have been made):

(i) when the Shelf Registration Statement or any amendment thereto has been filed with the Commission and when the Shelf Registration Statement or any post-effective amendment thereto has become effective;

(ii) of any request by the Commission for amendments or supplements to the Shelf Registration Statement or the Prospectus or for additional information;

(iii) of the issuance by the Commission of any stop order suspending the effectiveness of the Shelf Registration Statement or the initiation of any proceedings for that purpose;

(iv) of the receipt by the Company or its legal counsel of any notification with respect to the suspension of the qualification of the Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and

(v) of the happening of any event that requires the Company to make changes in the Shelf Registration Statement or the Prospectus in order that the Shelf Registration Statement or the Prospectus does not contain an untrue statement of a material fact nor omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of the Prospectus, in light of the circumstances under which they were made) not misleading, which written notice need not provide any detail as to the nature of such event.

(c) The Company shall make every reasonable effort to obtain the withdrawal at the earliest possible time, of any order suspending the effectiveness of the Shelf Registration Statement.

(d) The Company shall furnish to each Holder of Securities included within the coverage of the Shelf Registration, without charge, at least one copy of the Shelf Registration Statement and any post-effective amendment

thereto, including financial statements and schedules, and, if the Holder so requests in writing, all exhibits thereto (including those, if any, incorporated by reference).

(e) The Company shall, during the Shelf Registration Period, deliver to each Holder of Securities included within the coverage of the Shelf Registration, without charge, as many copies of the Prospectus (including each preliminary Prospectus) included in the Shelf Registration Statement and any amendment or supplement thereto as such person may reasonably request. The Company consents, subject to the provisions of this Agreement, to the use of the Prospectus or any amendment or supplement thereto by each of the selling Holders of the Securities in connection with the offering and sale of the Securities covered by the Prospectus, or any amendment or supplement thereto, included in the Shelf Registration Statement.

(f) Prior to any public offering of the Securities pursuant to the Shelf Registration Statement, the Company shall register or qualify or cooperate with the Holders of the Securities included therein and their respective counsel in connection with the registration or qualification of the Securities for offer and sale under the securities or “blue sky” laws of such states of the United States as any Holder of the Securities reasonably requests in writing and do any and all other acts or things necessary or advisable to enable the offer and sale in such jurisdictions of the Securities covered by such Registration Statement; provided, however, that the Company shall not be required to (i) qualify generally to do business in any jurisdiction where it is not then so qualified or (ii) take any action which would subject it to general service of process or to taxation in any jurisdiction where it is not then so subject.

(g) The Company shall cooperate with the Holders of the Securities to facilitate the timely preparation and delivery of certificates representing the Securities to be sold pursuant to any Registration Statement free of any restrictive legends and in such denominations and registered in such names as the Holders may request a reasonable period of time prior to sales of the Securities pursuant to the Shelf Registration Statement.

(h) Upon the occurrence of any event contemplated by paragraphs (ii) through (v) of Section 2(b) above during the period for which the Company is required to maintain an effective Shelf Registration Statement, the Company shall as required hereby prepare and file a post-effective amendment to the Shelf Registration Statement or an amendment or supplement to the Prospectus and any other required document so that, as thereafter delivered to Holders or purchasers of the Securities included within the coverage of such Shelf Registration Statement, the Prospectus will not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; provided, however, that the Company may delay filing and distributing any such supplement or amendment (and continue the suspension of the use of the Prospectus) if the Company determines in good faith that such supplement or amendment would, in the reasonable judgment of the Company, (i) interfere with or affect the negotiation or completion of a transaction that is being contemplated by the Company or (ii) involve initial or continuing disclosure obligations that are not in the best interests of the Company’s stockholders at such time; provided, further, that neither such delay nor such suspension shall extend for a period of more than 90 consecutive days or an aggregate of 120 days in any twelve-month period. If the Company notifies the Initial Purchaser and the Holders in accordance with paragraphs (ii) through (v) of Section 2(b) above to suspend the use of the Prospectus until the requisite changes to the Prospectus have been made, then the Initial Purchaser and the Holders shall suspend use of such Prospectus, and the period of effectiveness of the Shelf Registration Statement provided for in Section 1(b) above shall be extended by the number of days from and including the date of the giving of such notice to and including the date when the Initial Purchaser and the Holders shall have received such amended or supplemented Prospectus pursuant to this Section 2(h).

(i) Not later than the effective date of the Shelf Registration Statement, the Company will provide CUSIP numbers for the Initial Securities and the Common Stock registered under the Shelf Registration Statement, and provide the Trustee with printed certificates for the Initial Securities, in a form eligible for deposit with The Depository Trust Company.

(j) The Company will comply with all rules and regulations of the Commission to the extent and so long as they are applicable to the Shelf Registration and will make generally available to its security holders (or otherwise provide in accordance with Section 11(a) of the Securities Act) an earnings statement satisfying the provisions of Section 11(a) of the Securities Act, no later than 45 days after the end of a 12-month period (or 90 days, if such

period is a fiscal year) beginning with the first month of the Company’s first fiscal quarter commencing after the effective date of the Shelf Registration Statement, which statement shall cover such 12-month period.

(k) The Company shall cause the Indenture to be qualified under the Trust Indenture Act of 1939, as amended, (the “Trust Indenture Act”) in a timely manner and containing such changes, if any, as shall be necessary for such qualification. In the event that such qualification would require the appointment of a new trustee under the Indenture, the Company shall appoint a new trustee thereunder pursuant to the applicable provisions of the Indenture.

(l) Each Holder agrees, by acquisition of the Securities, that no Holder shall be entitled to sell any such Securities pursuant to the Shelf Registration Statement or to receive a prospectus relating thereto, unless such Holder has furnished the Company with a Notice and Questionnaire as required pursuant to and in accordance with Section 2(m) hereof and the information set forth in the next sentence. Each Holder agrees promptly to furnish the Company all information required to be disclosed in order to make the information previously furnished to the Company by such Holder not misleading and any other information regarding such Holder and the distribution of such Securities as the Company may from time to time reasonably request.

(m) Each Holder agrees that if such Holder wishes to sell such Holder’s Securities pursuant to the Shelf Registration Statement and related Prospectus, it will do so in accordance with this Section 2(m). Each Holder wishing to sell Securities pursuant to a Shelf Registration Statement and related prospectus agrees to deliver a properly, completely and signed Notice and Questionnaire (included in the Offering Circular, as defined in the Purchase Agreement, as Annex A and the form attached hereto) to the Company at least fifteen business days prior to any intended distribution of Securities under the Shelf Registration Statement. From and after the date the Shelf Registration Statement is declared effective, the Company shall, as promptly as is practicable after the date a Notice and Questionnaire is delivered, and in any event within 15 business days after such date, (i) if required by law, file with the Commission a post-effective amendment to the Registration Statement or prepare and, if required by applicable law, file a supplement to the related prospectus or a supplement or amendment to any document incorporated therein by reference or file any other required document so that the Holder delivering such Notice and Questionnaire is named a selling securityholder in the Registration Statement and the related Prospectus in such a manner as to permit such Holder to deliver such Prospectus to purchasers of the Securities in accordance with applicable law and, if the Company shall file a post-effective amendment to the Registration Statement, use all commercially reasonable efforts to cause such post-effective amendment to be declared effective under the Securities Act as promptly as practical, but in any event by the date that is thirty 30 business days after the date such post-effective amendment is required by this clause to be filed; (ii) provide such Holder copies of any documents filed pursuant to this Section; and (iii) notify such Holder as promptly as practicable after the effectiveness under the Securities Act of any post-effective amendment filed pursuant to this Section; provided, that if such Notice and Questionnaire is delivered during a period in which the use of such Prospectus is suspended pursuant to Section 2(c) hereof, the Company shall so inform the Holder delivering such Notice and Questionnaire and shall take the actions set forth in clauses (i), (ii) and (iii) above upon expiration of such suspension period. Notwithstanding anything contained herein to the contrary, the Company shall be under no obligation to name any Holder that has not supplied the requisite information as required by and in accordance with the procedures and time periods set forth in this section as a selling securityholder in the Registration Statement and related prospectus and any amendment or supplement thereto; provided, however, that any Holder that has subsequently supplied the requisite information required by this Section pursuant to the provisions of this Section (whether or not such Holder has supplied the requisite information required by this Section at the time the Registration Statement was declared effective) shall be named as a selling securityholder in the Registration Statement or related prospectus in accordance with the requirements of this Section. Notwithstanding anything contained herein to the contrary, the Company shall not be required to file more than one post-effective amendment or supplement for the purpose of naming selling security holders in any seven-day period.

(n) The Company shall enter into such customary agreements reasonably satisfactory to the Company (including, if requested, an underwriting agreement in customary form) and take all such other reasonable actions in connection therewith, if any, as any Holder shall reasonably request in order to facilitate the disposition of the Securities pursuant to the Shelf Registration; provided, however, that the Company shall not be required to facilitate an underwritten offering pursuant to a Shelf Registration Statement by any Holders unless the offering relates to at least $20,000,000 principal amount of the Initial Securities or an equivalent amount of Common Stock.

(o) The Company shall (i) make reasonably available for inspection by the Holders, any underwriter participating in any disposition pursuant to the Shelf Registration Statement and any attorney, accountant or other agent retained by such Holders or any such underwriter (collectively, the “Inspectors”) at the offices where normally kept, during reasonable business hours, all relevant financial and other records, pertinent corporate documents and properties of the Company as they may reasonably request and (ii) cause the Company’s officers, directors, employees, accountants and auditors to supply all relevant information reasonably requested by the Holders or any such underwriter, attorney, accountant or agent in connection with the Shelf Registration Statement, in each case, as shall be reasonably necessary to enable such persons, to conduct a reasonable investigation within the meaning of Section 11 of the Securities Act; provided, however, that the foregoing inspection and information gathering shall be coordinated on behalf of the Initial Purchaser by you and on behalf of the other parties, by one counsel designated by and on behalf of such other parties as described in Section 3 hereof. Records which the Company reasonably determines, in good faith, to be confidential and any records which they notify the Inspectors are confidential shall not be disclosed by the Inspectors unless (i) the disclosure of such records is necessary to avoid or correct a material misstatement or omission in such Registration Statement after a failure by the Company to make such disclosure for a period of 5 business days after receiving written notice from any Inspector of the need to make such disclosure, (ii) the release of such records is ordered pursuant to a subpoena or other order from a court of competent jurisdiction or (iii) the information in such records has been made generally available to the public. Each selling Holder of such Registrable Securities and each such Participating Broker-Dealer will be required to agree in writing that information obtained by it as a result of such inspections shall be deemed confidential and shall not be used by it as the basis for any market transactions in the securities of the Company unless and until such is made generally available to the public. Each selling Holder of such Registrable Securities and each such Participating Broker-Dealer will be required to further agree in writing that it will, upon learning that disclosure of such records is sought in a court of competent jurisdiction, give notice to the Company and allow the Company at its expense to undertake appropriate action to prevent disclosure of the records deemed confidential.

(p) In the event of an underwritten offering, the Company, if requested by any Holder of Securities covered by the Shelf Registration Statement shall (i) seek to obtain from its counsel an opinion and updates thereof relating to the Securities in customary form, addressed to such Holders and the managing underwriters, thereof, and dated, in the case of the initial opinion, the effective date of such Shelf Registration Statement, which shall be reasonably satisfactory to such underwriters, (ii) cause its officers to execute and deliver all customary documents and certificates and updates thereof reasonably requested by any underwriters of the Securities and (iii) seek to obtain from its independent public accountants and the independent public accountants with respect to any other entity for which financial information is provided in the Shelf Registration Statement to provide to the selling Holders of the applicable Securities and any underwriter therefor a comfort letter in customary form and covering matters of the type customarily covered in comfort letters in connection with primary underwritten offerings, subject to receipt of appropriate documentation as contemplated, and only if permitted, by Statement of Auditing Standards No. 72.

(q) The Company shall use its commercially reasonable efforts to take all other steps necessary to effect the registration of the Securities covered by a Registration Statement contemplated hereby.

3. Registration Expenses. (a) The Company shall bear all fees and expenses incurred in connection with the performance of its obligations under Sections 1 and 2 hereof, whether or not a Shelf Registration Statement is filed or becomes effective and shall bear or reimburse the Holders of the Securities covered thereby for reasonable fees and disbursements of not more than one counsel, designated by the Holders of a majority in principal amount of the Securities covered by the Shelf Registration Statement (provided that Holders of Common Stock issued upon the conversion of the Initial Securities shall be deemed to be Holders of the aggregate principal amount of Initial Securities from which such Common Stock was converted) to act as counsel for the Holders in connection therewith.

(b) Except as provided in Section 3(a) hereunder, each Holder shall pay all expenses of its counsel, underwriting discounts and commissions, and transfer taxes, if any, relating to the sale or disposition of such Holder’s Transfer Restricted Securities pursuant to a Shelf Registration Statement.

4. Indemnification. (a) The Company agrees to indemnify and hold harmless each Holder and each person, if any, who controls such Holder within the meaning of the Securities Act or the Exchange Act (each Holder, and such controlling persons are referred to collectively as the “Indemnified Parties”) from and against any losses,

claims, damages or liabilities, joint or several, or any actions in respect thereof (including, but not limited to, any losses, claims, damages, liabilities or actions relating to purchases and sales of the Securities) to which each Indemnified Party may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Shelf Registration Statement or Prospectus including any document incorporated by reference therein, or in any amendment or supplement thereto or in any preliminary prospectus relating to the Shelf Registration, or arise out of, or are based upon, 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, and shall reimburse, as incurred, the Indemnified Parties for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action in respect thereof; provided, however, that (i) the Company shall not be liable in any such case to the extent that such loss, claim, damage or liability arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made in the Shelf Registration Statement or Prospectus or in any amendment or supplement thereto or in any preliminary prospectus relating to the Shelf Registration in reliance upon and in conformity with written information pertaining to such Holder and furnished to the Company by or on behalf of such Holder specifically for inclusion therein and (ii) with respect to any untrue statement or omission or alleged untrue statement or omission made in any preliminary prospectus relating to the Shelf Registration Statement, the indemnity agreement contained in this subsection (a) shall not inure to the benefit of any Holder from whom the person asserting any such losses, claims, damages or liabilities purchased the Securities concerned, to the extent that a prospectus relating to such Securities was required to be delivered by such Holder under the Securities Act in connection with such purchase and any such loss, claim, damage or liability of such Holder results from the fact that there was not sent or given to such person, at or prior to the written confirmation of the sale of such Securities to such person, a copy of the final Prospectus if the Company had previously furnished copies thereof to such Holder; provided further, however, that this indemnity agreement will be in addition to any liability which the Company may otherwise have to such Indemnified Party. The Company shall also indemnify underwriters, their officers and directors and each person who controls such underwriters within the meaning of the Securities Act or the Exchange Act to the same extent as provided above with respect to the indemnification of the Holders of the Securities if requested by such Holders.

(b) Each Holder, severally and not jointly, will indemnify and hold harmless the Company, its officers and directors and each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act from and against any losses, claims, damages or liabilities or any actions in respect thereof, to which the Company or any such controlling person may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, claims, damages, liabilities or actions arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Shelf Registration Statement or Prospectus or in any amendment or supplement thereto or in any preliminary prospectus relating to the Shelf Registration, or arise out of or are based upon the omission or alleged omission to state therein a material fact necessary to make the statements therein not misleading, but in each case only to the extent that the untrue statement or omission or alleged untrue statement or omission was made in reliance upon and in conformity with written information pertaining to such Holder and furnished to the Company by or on behalf of such Holder specifically for inclusion therein; and, subject to the limitation set forth immediately preceding this clause, shall reimburse, as incurred, the Company for any legal or other expenses reasonably incurred by the Company or any such controlling person in connection with investigating or defending any loss, claim, damage, liability or action in respect thereof. This indemnity agreement will be in addition to any liability which such Holder may otherwise have to the Company or any of its controlling persons.

(c) Promptly after receipt by an indemnified party under this Section 4 of notice of the commencement of any action or proceeding (including a governmental investigation), such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 4, notify the indemnifying party of the commencement thereof; but the failure to notify the indemnifying party shall not relieve it from any liability that it may have under subsection (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under subsection (a) or (b) above. In case any such action is brought against any indemnified party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense

thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof the indemnifying party will not be liable to such indemnified party under this Section 4 for any legal or other expenses, other than reasonable costs of investigation, subsequently incurred by such indemnified party in connection with the defense thereof. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement (i) includes an unconditional release of such indemnified party from all liability on any claims that are the subject matter of such action, and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party. No indemnified party shall effect any settlement of any pending or threatened action without the prior written consent of the indemnifying party, which such consent shall not be unreasonably withheld or delayed.

(d) If the indemnification provided for in this Section 4 is unavailable or insufficient to hold harmless an indemnified party under subsections (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to in subsection (a) or (b) above in such proportion as is appropriate to reflect the relative benefits received by the indemnifying party or parties on the one hand and the indemnified party on the other from the sale of the Securities, pursuant to the Shelf Registration, or (ii) if the allocation provided by the foregoing clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the indemnifying party or parties on the one hand and the indemnified party on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities (or actions in respect thereof) as well as any other relevant equitable considerations. The relative fault of the parties shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or such Holder or such other indemnified party, as the case may be, on the other, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding any other provision of this Section 4(d), the Holders shall not be required to contribute any amount in excess of the amount by which the net proceeds received by such Holders from the sale of the Securities pursuant to the Shelf Registration Statement exceeds the amount of damages which such Holders have otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this paragraph (d), each person, if any, who controls such indemnified party within the meaning of the Securities Act or the Exchange Act shall have the same rights to contribution as such indemnified party and each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act shall have the same rights to contribution as the Company.

(e) The agreements contained in this Section 4 shall survive the sale of the Securities pursuant to the Shelf Registration Statement and shall remain in full force and effect, regardless of any termination or cancellation of this Agreement or any investigation made by or on behalf of any indemnified party.

5. Additional Interest Under Certain Circumstances. (a) Additional interest (the “Additional Interest”) with respect to the Initial Securities shall be assessed as follows if any of the following events occur (each such event in clauses (i) through (iv) below being herein called a “Registration Default”):

(i) the Shelf Registration Statement has not been filed with the Commission by the 90th day after the first date of original issuance of the Initial Securities;

(ii) the Shelf Registration Statement has not been declared effective by the Commission by the 180th day after the first date of original issue of the Initial Securities; or

(iii) the Company fails with respect to a Holder that supplies the Notice and Questionnaire described in Paragraph 2(m) to amend or supplement the Registration Statement in the manner set forth in 2(m); provided that such assessment shall be paid only to such Holder and directly to such Holder; or

(iv) the Shelf Registration Statement is declared effective, and such Shelf Registration Statement ceases to be effective or fails to be usable in connection with resales of the Initial Securities and the Transfer Restricted Securities issuable upon the conversion of the Initial Securities in accordance with and during the periods specified in this Agreement (including without limitation pursuant to Section 2(h) above) and (A) the Company does not cure the Shelf Registration Statement within five business days by a post-effective amendment or a report filed pursuant to the Exchange Act or (B) if applicable, the Company does not terminate the suspension period described above by the 90th or 120th day, as the case may be.

Each of the foregoing will constitute a Registration Default whatever the reason for any such event and whether it is voluntary or involuntary or is beyond the control of the Company or pursuant to operation of law or as a result of any action or inaction by the Commission .

Additional Interest shall accrue on the Initial Securities over and above the interest set forth in the title of the Initial Securities from and including the date on which any such Registration Default shall occur to but excluding the date on which all such Registration Defaults have been cured, at a rate of 0.50% per annum (the “Additional Interest Rate”) (or an equivalent amount of any Common Stock issued upon conversion of the Initial Securities). The Company shall have no other liabilities for monetary damages with respect to its registration obligations. With respect to each Holder, the Company’s obligations to pay additional interest remain in effect only so long as the Initial Securities and the Common Stock issuable upon the conversion of the Initial Securities held by the Holder are Transfer Restricted Securities within the meaning of this Agreement.

(b) A Registration Default referred to in Section 5(a)(iv) hereof shall be deemed not to have occurred and be continuing in relation to the Shelf Registration Statement or the related prospectus if (i) such Registration Default has occurred solely as a result of (x) the filing of a post-effective amendment to the Shelf Registration Statement to incorporate annual audited financial information with respect to the Company where such post-effective amendment is not yet effective and needs to be declared effective to permit Holders to use the related Prospectus or (y) other material events, with respect to the Company that would need to be described in such Shelf Registration Statement or the related Prospectus and (ii) in the case of clause (y), the Company is proceeding promptly and in good faith to amend or supplement the Shelf Registration Statement and related Prospectus to describe such events as required by paragraph 2(h) hereof; provided, however, that in any case if such Registration Default occurs for a continuous period in excess of 30 days, Additional Interest shall be payable in accordance with the above paragraph from the day such Registration Default occurs until such Registration Default is cured.

(c) Any amounts of Additional Interest due pursuant to Section 5(a) will be payable in cash on the regular interest payment dates with respect to the Initial Securities. The amount of Additional Interest will be determined by multiplying the applicable Additional Interest Rate by the principal amount of the Initial Securities, further multiplied by a fraction, the numerator of which is the number of days such Additional Interest Rate was applicable during such period (determined on the basis of a 360-day year comprised of twelve 30-day months), and the denominator of which is 360.

(d) “Transfer Restricted Securities” means each Security until (i) the date on which such Security has been effectively registered under the Securities Act and disposed of in accordance with the Shelf Registration Statement or (ii) the date on which such Security may be sold to the public pursuant to Rule 144 under the Securities Act or is saleable pursuant to Rule 144(k) under the Securities Act. Notwithstanding anything herein to the contrary, the registration rights granted hereunder shall terminate as to each Holder and with respect to such Securities upon the date that such Securities are no longer Transfer Restricted Securities.

6. Rules 144 and 144A. The Company shall use its reasonable best efforts to file the reports required to be filed by it under the Securities Act and the Exchange Act in a timely manner and, if at any time the Company is not required to file such reports, it will, upon the request of any Holder, make publicly available other information so long as necessary to permit sales of their securities pursuant to Rules 144 and 144A. The Company covenants that it will take such further action as any Holder may reasonably request, all to the extent required from time to time to

enable such Holder to sell Transfer Restricted Securities without registration under the Securities Act within the limitation of the exemptions provided by Rules 144 and 144A (including the requirements of Rule 144A(d)(4)). The Company will provide a copy of this Agreement to prospective purchasers of Securities identified to the Company by the Initial Purchaser upon request. Upon the request of any Holder, the Company shall deliver to such Holder a written statement as to whether it has complied with such requirements. Notwithstanding the foregoing, nothing in this Section 6 shall be deemed to require the Company to register any of its securities pursuant to the Exchange Act.

7. Underwritten Registrations. If any of the Transfer Restricted Securities covered by the Shelf Registration are to be sold in an underwritten offering, the investment banker or investment bankers and manager or managers that will administer the offering (“Managing Underwriters”) will be selected by the holders of a majority in aggregate principal amount of such Transfer Restricted Securities to be included in such offering (provided that holders of Common Stock issued upon conversion of the Initial Securities shall not be deemed holders of Common Stock, but shall be deemed to be holders of the aggregate principal amount of Initial Securities from which such Common Stock was converted) and such selection shall be subject to the Company’s consent, which shall not be unreasonably withheld or delayed.

No person may participate in any underwritten registration hereunder unless such person (i) agrees to sell such person’s Transfer Restricted Securities on the basis reasonably provided in any underwriting arrangements approved by the persons entitled hereunder to approve such arrangements and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements.

8. Miscellaneous.

(a) Remedies. The Company acknowledges and agrees that any failure by the Company to comply with its obligations hereunder may result in material irreparable injury to the Initial Purchaser or the Holders for which there is no adequate remedy at law, that it will not be possible to measure damages for such injuries precisely and that, in the event of any such failure, the Initial Purchaser or any Holder may obtain such relief as may be required to specifically enforce the Company’s obligations hereunder.

(b) No Inconsistent Agreements. The Company will not on or after the date of this Agreement enter into any agreement with respect to its securities that is inconsistent with the rights granted to the Holders in this Agreement or otherwise conflicts with the provisions hereof. The rights granted to the Holders hereunder do not in any way conflict with and are not inconsistent with the rights granted to the holders of the Company’s securities under any agreement in effect on the date hereof. Subject to the foregoing, the Company shall not be limited or in any way prevented from entering into any agreement granting any holder or prospective holder of any securities of the Company registration rights with respect to such securities.

(c) Amendments and Waivers. The provisions of this Agreement may not be amended, modified or supplemented, and waivers or consents to departures from the provisions hereof may not be given, except by the Company and the written consent of the holders of a majority in principal amount of the Securities affected by such amendment, modification, supplement, waiver or consents (provided that holders of Common Stock issued upon conversion of Initial Securities shall not be deemed holders of Common Stock, but shall be deemed to be holders of the aggregate principal amount of Initial Securities from which such Common Stock was converted).

(d) Notices. All notices and other communications provided for or permitted hereunder shall be made in writing by hand delivery, first-class mail, facsimile transmission, or air courier which guarantees overnight delivery:

(1)		if to a Holder of the Securities, at the most current address given by such Holder to the Company.
