incurred pursuant to Section 7.03(g) of the Senior Credit Agreement if such Equity Interests serve as security for such Indebtedness or if the terms of such Indebtedness prohibit the creation of any other lien on such Equity Interests, (E) more than 65% of the issued and outstanding voting Equity Interests of any Material Foreign Subsidiary that is a direct or indirect subsidiary of Holdings, (F) Equity Interests of any Foreign Subsidiary that is not a Material Foreign Subsidiary, (G) Equity Interests of any Subsidiary of a Foreign Subsidiary that is a direct or indirect Subsidiary of Holdings, (H) Equity Interests of any Foreign Subsidiary that are pledged pursuant to a Foreign Pledge Agreement, (I) Equity Interests of any Person that is not an indirect, wholly owned Subsidiary of Holdings III, (J) (i) if there are outstanding Obligations under the Senior Credit Facilities, any asset with respect to which the Administrative Agent has confirmed in writing to the Issuer its determination that the costs of providing a security interest in such asset or perfection thereof is excessive in view of the benefits to be obtained by the secured parties under the Senior Credit Agreement or (ii) if there are no outstanding Obligations under the Senior Credit Facilities, any asset with respect to which the board of directors or the senior management of the Issuer has confirmed in writing to the Trustee and the Notes Collateral Agent its reasonable determination that the costs of providing a security interest in such asset or perfection thereof is excessive in view of the benefits to be obtained by the Secured Parties, (K) security interests prohibited by law or by agreements containing anti-assignment clauses not overridden by the UCC or other applicable law or (L) any General Intangible, Investment Property or other rights of a Grantor arising under any contract, lease, instrument, license or other document or any assets subject thereto if (but only to the extent that) the grant of a security interest therein would (x) constitute a violation of a valid and enforceable restriction in respect of such General Intangible, Investment Property or other such rights in favor of a third party or under any law, regulation, permit, order or decree of any Governmental Authority, unless and until all required consents shall have been obtained (for the avoidance of doubt, the restrictions described herein shall not include negative pledges or similar undertakings in favor of a lender or other financial counterparty) or (y) expressly give any other party in respect of any such contract, lease, instrument, license or other document, the right to terminate its obligations thereunder, provided, however, that the limitation set forth in clause (L) above shall not affect, limit, restrict or impair the grant by a Grantor of a security interest pursuant to this Agreement in any such Collateral to the extent that an otherwise applicable prohibition or restriction on such grant is rendered ineffective by any applicable law, including the Uniform Commercial Code.  Each Grantor shall, if requested to do so by the Trustee, use commercially reasonable efforts to obtain any such required consent that is reasonably obtainable with respect to Collateral which the Trustee reasonably determines to be material.

(b)  Each Grantor hereby irrevocably authorizes the Notes Collateral Agent for the benefit of the Secured Parties at any time and from time to time to file in any relevant jurisdiction any initial financing statements (including fixture filings) with respect to the Article 9 Collateral or any part thereof and amendments thereto that (i) indicate the Collateral as all assets of such Grantor or words of similar effect as being of an equal or lesser scope or with greater detail, and (ii) contain the information required by Article 9 of the Uniform Commercial Code or the analogous legislation of each applicable jurisdiction for the filing of any financing statement or amendment, including

13

(A) whether such Grantor is an organization, the type of organization and any organizational identification number issued to such Grantor and (B) in the case of a financing statement filed as a fixture filing, a sufficient description of the real property to which such Article 9 Collateral relates.  Each Grantor agrees to provide such information to the Notes Collateral Agent promptly upon request.

(c)  The Security Interest is granted as security only and shall not subject the Notes Collateral Agent or any other Secured Party to, or in any way alter or modify, any obligation or liability of any Grantor with respect to or arising out of the Article 9 Collateral.

(d)  Notwithstanding anything to the contrary in this Agreement or the Indenture, none of the Grantors shall be required to enter into any deposit account control agreement or securities account control agreement with respect to any deposit account or securities account.

SECTION 3.02.  Representations and Warranties.  Holdings V, the Issuer and SigmaTel jointly and severally represent and warrant, as to themselves and the other Grantors, to the Notes Collateral Agent and the Secured Parties that:

(a)  Each Grantor has good and valid rights in and title to the Article 9 Collateral with respect to which it has purported to grant a Security Interest hereunder and has full power and authority to grant to the Notes Collateral Agent the Security Interest in such Article 9 Collateral pursuant hereto and to execute, deliver and perform its obligations in accordance with the terms of this Agreement, without the consent or approval of any other Person other than any consent or approval that has been obtained.

(b)  The Perfection Certificate has been duly prepared, completed and executed and the information set forth therein, including the exact legal name of each Grantor, is correct and complete in all material respects as of the Closing Date.  The UCC financing statements (including fixture filings, as applicable) or other appropriate filings, recordings or registrations prepared by the Notes Collateral Agent based upon the information provided to the Notes Collateral Agent in the Perfection Certificate for filing in each governmental, municipal or other office specified in Schedule 6 to the Perfection Certificate (or specified by notice from the Issuer to the Notes Collateral Agent after the Closing Date in the case of filings, recordings or registrations required by the Indenture), are all the filings, recordings and registrations that are necessary to establish a legal, valid and perfected security interest in favor of the Notes Collateral Agent (for the benefit of the Secured Parties) in respect of all Article 9 Collateral in which the Security Interest may be perfected by filing, recording or registration in the United States (or any political subdivision thereof) and its territories and possessions pursuant to the Uniform Commercial Code in the relevant jurisdiction, and no further or subsequent filing, refiling, recording, rerecording, registration or reregistration is necessary in any such jurisdiction, except as provided under applicable law with respect to the filing of continuation statements.

14

(c)  The Security Interest constitutes (i) a legal and valid security interest in all the Article 9 Collateral securing the payment and performance of the Secured Obligations and (ii) subject to the filings described in Section 3.02(b), a perfected security interest in all Article 9 Collateral in which a security interest may be perfected by filing, recording or registering a financing statement or analogous document in the United States (or any political subdivision thereof) and its territories and possessions pursuant to the Uniform Commercial Code in the relevant jurisdiction.  The Security Interest is and shall be prior to any other Lien on any of the Article 9 Collateral, other than (i) any nonconsenual Lien that is expressly permitted pursuant to Section 4.12 of the Indenture and has priority as a matter of law and (ii) Liens expressly permitted pursuant to Section 4.12 of the Indenture.

(d)  The Article 9 Collateral is owned by the Grantors free and clear of any Liens, except for Liens expressly permitted pursuant to Section 4.12 of the Indenture.  None of the Grantors has filed or consented to the filing of (i) any financing statement or analogous document under the New York UCC or any other applicable laws covering any Article 9 Collateral or (ii) any assignment in which any Grantor assigns any Article 9 Collateral or any security agreement or similar instrument covering any Article 9 Collateral with any foreign governmental, municipal or other office, which financing statement or analogous document, assignment, security agreement or similar instrument is still in effect, except, in each case, for Liens expressly permitted pursuant to Section 4.12 of the Indenture.

SECTION 3.03.  Covenants.

(a)  The Issuer agrees promptly to notify the Notes Collateral Agent in writing of any change (i) in legal name of any Grantor, (ii) in the identity or type of organization or corporate structure of any Grantor, or (iii) in the jurisdiction of organization of any Grantor.

(b)  Each Grantor shall, at its own expense, take any and all commercially reasonable actions necessary to defend title to the Article 9 Collateral against all Persons and to defend the Security Interest of the Notes Collateral Agent in the Article 9 Collateral and the priority thereof against any Lien not expressly permitted pursuant to Section 4.12 of the Indenture.

(c)  Each year, at the time of delivery of annual financial statements with respect to the preceding fiscal year pursuant to Section 4.03 of the Indenture, the Issuer shall deliver to the Notes Collateral Agent a certificate executed by the chief financial officer and the chief legal officer of the Issuer setting forth the information required pursuant to Sections 1(a), 1(c), 1(d), 2(b) and 12 of the Perfection Certificate or confirming that there has been no change in such information since the date of such certificate or the date of the most recent certificate delivered pursuant to this Section 3.03(c) and certifying that all UCC financing statements and other appropriate filings, recordings or registrations have been filed of record in each governmental, municipal or other appropriate office in each jurisdiction necessary to protect and perfect the Security Interests and Liens under this Agreement and the Intellectual Property Security

15

Agreement for a period of not less than 18 months after the date of such certificate (except as noted therein with respect to any continuation statements to be filed within such period).

(d)  The Issuer and the Grantors shall, at their sole expense, do all acts which may be reasonably necessary, if requested by the Notes Collateral Agent, to confirm that the Notes Collateral Agent holds, for the benefit of the Holders, duly created, enforceable and perfected First Liens in the Collateral (subject to Permitted Liens) to the extent required by the Indenture and the Collateral Documents relating to the Notes.  The Issuer agrees, on its own behalf and on behalf of each other Grantor, at its own expense, to execute, acknowledge, deliver and cause to be duly filed all such further instruments and documents and take all such actions as the Notes Collateral Agent may from time to time reasonably request to better assure, preserve, protect, perfect, transfer and confirm the Security Interest and the rights and remedies created hereby, including the payment of any fees and taxes required in connection with the execution and delivery of this Agreement, the granting of the Security Interest and the filing of any financing statements (including fixture filings) or other documents in connection herewith or therewith.  Subject to the terms of the Intercreditor Agreement, if any amount payable under or in connection with any of the Article 9 Collateral that is in excess of $10,000,000 shall be or become evidenced by any promissory note or other instrument, such note or instrument shall be promptly pledged and delivered to the Notes Collateral Agent, for the benefit of the Secured Parties, duly endorsed in a manner reasonably satisfactory to the Notes Collateral Agent.

(e)  Subject to the terms of the Intercreditor Agreement, at its option, the Notes Collateral Agent may discharge past due taxes, assessments, charges, fees, Liens, security interests or other encumbrances at any time levied or placed on the Article 9 Collateral and not permitted pursuant to Section 4.12 of the Indenture, and may pay for the maintenance and preservation of the Article 9 Collateral to the extent any Grantor fails to do so as required by the Indenture or this Agreement and within a reasonable period of time after the Notes Collateral Agent has requested that it do so, and each Grantor jointly and severally agrees to reimburse the Notes Collateral Agent within 10 days after demand for any payment made or any reasonable expense incurred by the Notes Collateral Agent pursuant to the foregoing authorization.  Nothing in this paragraph shall be interpreted as excusing any Grantor from the performance of, or imposing any obligation on the Notes Collateral Agent or any Secured Party to cure or perform, any covenants or other promises of any Grantor with respect to taxes, assessments, charges, fees, Liens, security interests or other encumbrances and maintenance as set forth herein, or in the other Notes Documents.

(f)  If at any time any Grantor shall take a security interest in any property of an Account Debtor or any other Person, the value of which is in excess of $10,000,000, to secure payment and performance of an Account, such Grantor shall promptly assign such security interest to the Notes Collateral Agent for the benefit of the Secured Parties.  Such assignment need not be filed of public record unless necessary to continue the perfected status of the security interest against creditors of and transferees from the Account Debtor or other Person granting the security interest.

16

(g)  Each Grantor (rather than the Notes Collateral Agent or any Secured Party) shall remain liable (as between itself and any relevant counterparty) to observe and perform all the conditions and obligations to be observed and performed by it under each contract, agreement or instrument relating to the Article 9 Collateral, all in accordance with the terms and conditions thereof, and each Grantor jointly and severally agrees to indemnify and hold harmless the Notes Collateral Agent and the Secured Parties from and against any and all liability for such performance.

(h)  If any Grantor shall at any time hold or acquire a Commercial Tort Claim with a value in excess of $10,000,000, such Grantor shall promptly notify the Notes Collateral Agent in writing signed by such Grantor of the brief details thereof and grant to the Notes Collateral Agent a security interest therein and in the Proceeds thereof, all upon the terms of this Agreement pursuant to a document in form and substance reasonably satisfactory to the Notes Collateral Agent.

SECTION 3.04.  Other Actions.  Subject to the terms of the Intercreditor Agreement, in order to further insure the attachment, perfection and priority of, and the ability of the Notes Collateral Agent to enforce, the Security Interest, each Grantor agrees, in each case at such Grantor’s own expense, to take the following actions with respect to the following Article 9 Collateral:

(a)  Instruments.  If any Grantor shall at any time hold or acquire any Instruments constituting Collateral and evidencing an amount in excess of $10,000,000, such Grantor shall forthwith endorse, assign and deliver the same to the Notes Collateral Agent for the benefit of the Secured Parties, accompanied by such instruments of transfer or assignment duly executed in blank as the Notes Collateral Agent may from time to time reasonably request.

(b)  Investment Property.  Except to the extent otherwise provided in Article II, if any Grantor shall at any time hold or acquire any certificated securities, such Grantor shall forthwith endorse, assign and deliver the same to the Notes Collateral Agent for the benefit of the Secured Parties, accompanied by such instruments of transfer or assignment duly executed in blank as the Notes Collateral Agent may from time to time reasonably request.  If any securities now or hereafter acquired by any Grantor are uncertificated and are issued to such Grantor or its nominee directly by the issuer thereof, upon the Notes Collateral Agent’s request and following the occurrence of an Event of Default such Grantor shall promptly notify the Notes Collateral Agent thereof and, at the Notes Collateral Agent’s reasonable request, pursuant to an agreement in form and substance reasonably satisfactory to the Notes Collateral Agent, either (i) cause the issuer to agree to comply with instructions from the Notes Collateral Agent as to such securities, without further consent of any Grantor or such nominee, or (ii) arrange for the Notes Collateral Agent to become the registered owner of the securities.  If any securities, whether certificated or uncertificated, or other investment property are held by any Grantor or its nominee through a securities intermediary or commodity intermediary, upon the Notes Collateral Agent’s request and following the occurrence of an Event of Default, such Grantor shall immediately notify the Notes Collateral Agent thereof and at the Notes Collateral Agent’s request and option, pursuant to an agreement in form and

17

substance reasonably satisfactory to the Notes Collateral Agent shall either (i) cause such securities intermediary or (as the case may be) commodity intermediary to agree to comply with entitlement orders or other instructions from the Notes Collateral Agent to such securities intermediary as to such security entitlements, or (as the case may be) to apply any value distributed on account of any commodity contract as directed by the Notes Collateral Agent to such commodity intermediary, in each case without further consent of any Grantor or such nominee, or (ii) in the case of financial assets or other Investment Property held through a securities intermediary, arrange for the Notes Collateral Agent to become the entitlement holder with respect to such Investment Property, with the Grantor being permitted, only with the consent of the Notes Collateral Agent, to exercise rights to withdraw or otherwise deal with such Investment Property.  The Notes Collateral Agent agrees with each of the Grantors that the Notes Collateral Agent shall not give any such entitlement orders or instructions or directions to any such issuer, securities intermediary or commodity intermediary, and shall not withhold its consent to the exercise of any withdrawal or dealing rights by any Grantor, unless an Event of Default has occurred and is continuing.  The provisions of this paragraph shall not apply to any financial assets credited to a securities account for which the Notes Collateral Agent is the securities intermediary.

ARTICLE IV

Remedies

SECTION 4.01.  Remedies upon Default.  Subject to the terms of the Intercreditor Agreement, upon the occurrence and during the continuance of an Event of Default, it is agreed that the Notes Collateral Agent shall have the right to exercise any and all rights afforded to a secured party with respect to the Secured Obligations under the Uniform Commercial Code or other applicable law and also may (i) require each Grantor to, and each Grantor agrees that it will at its expense and upon request of the Notes Collateral Agent forthwith, assemble all or part of the Collateral as directed by the Notes Collateral Agent and make it available to the Notes Collateral Agent at a place and time to be designated by the Notes Collateral Agent that is reasonably convenient to both parties; (ii) occupy any premises owned or, to the extent lawful and permitted, leased by any of the Grantors where the Collateral or any part thereof is assembled or located for a reasonable period in order to effectuate its rights and remedies hereunder or under law, without obligation to such Grantor in respect of such occupation; provided that the Notes Collateral Agent shall provide the applicable Grantor with notice thereof prior to or promptly after such occupancy; (iii) exercise any and all rights and remedies of any of the Grantors under or in connection with the Collateral, or otherwise in respect of the Collateral; provided that the Notes Collateral Agent shall provide the applicable Grantor with notice thereof prior to or promptly after such exercise; and (iv) subject to the mandatory requirements of applicable law and the notice requirements described below, sell or otherwise dispose of all or any part of the Collateral securing the Secured Obligations at a public or private sale or at any broker’s board or on any securities exchange, for cash, upon credit or for future delivery as the Notes Collateral Agent shall deem appropriate.  The

18

Notes Collateral Agent shall be authorized at any such sale of securities (if it deems it advisable to do so) to restrict the prospective bidders or purchasers to Persons who will represent and agree that they are purchasing the Collateral for their own account for investment and not with a view to the distribution or sale thereof, and upon consummation of any such sale the Notes Collateral Agent shall have the right to assign, transfer and deliver to the purchaser or purchasers thereof the Collateral so sold.  Each such purchaser at any sale of Collateral shall hold the property sold absolutely, free from any claim or right on the part of any Grantor, and each Grantor hereby waives (to the extent permitted by law) all rights of redemption, stay and appraisal which such Grantor now has or may at any time in the future have under any rule of law or statute now existing or hereafter enacted.

The Notes Collateral Agent shall give the applicable Grantors 10 days’ written notice (which each Grantor agrees is reasonable notice within the meaning of Section 9-611 of the New York UCC or its equivalent in other jurisdictions) of the Notes Collateral Agent’s intention to make any sale of Collateral.  Such notice, in the case of a public sale, shall state the time and place for such sale and, in the case of a sale at a broker’s board or on a securities exchange, shall state the board or exchange at which such sale is to be made and the day on which the Collateral, or portion thereof, will first be offered for sale at such board or exchange.  Any such public sale shall be held at such time or times within ordinary business hours and at such place or places as the Notes Collateral Agent may fix and state in the notice (if any) of such sale.  At any such sale, the Collateral, or portion thereof, to be sold may be sold in one lot as an entirety or in separate parcels, as the Notes Collateral Agent may (in its sole and absolute discretion) determine.  The Notes Collateral Agent shall not be obligated to make any sale of any Collateral if it shall determine not to do so, regardless of the fact that notice of sale of such Collateral shall have been given.  The Notes Collateral Agent may, without notice or publication, adjourn any public or private sale or cause the same to be adjourned from time to time by announcement at the time and place fixed for sale, and such sale may, without further notice, be made at the time and place to which the same was so adjourned.  In case any sale of all or any part of the Collateral is made on credit or for future delivery, the Collateral so sold may be retained by the Notes Collateral Agent until the sale price is paid by the purchaser or purchasers thereof, but the Notes Collateral Agent shall not incur any liability in case any such purchaser or purchasers shall fail to take up and pay for the Collateral so sold and, in case of any such failure, such Collateral may be sold again upon like notice.  At any public (or, to the extent permitted by law, private) sale made pursuant to this Agreement, any Secured Party may bid for or purchase, free (to the extent permitted by law) from any right of redemption, stay, valuation or appraisal on the part of any Grantor (all said rights being also hereby waived and released to the extent permitted by law), the Collateral or any part thereof offered for sale and may make payment on account thereof by using any claim then due and payable to such Secured Party from any Grantor as a credit against the purchase price, and such Secured Party may, upon compliance with the terms of sale, hold, retain and dispose of such property without further accountability to any Grantor therefor.  For purposes hereof, a written agreement to purchase the Collateral or any portion thereof shall be treated as a sale thereof; the Notes Collateral Agent shall be free to carry out such sale pursuant to such agreement and no Grantor shall be entitled to the return of the Collateral

19

or any portion thereof subject thereto, notwithstanding the fact that after the Notes Collateral Agent shall have entered into such an agreement all Events of Default shall have been remedied and the Secured Obligations paid in full.  As an alternative to exercising the power of sale herein conferred upon it, the Notes Collateral Agent may proceed by a suit or suits at law or in equity to foreclose this Agreement and to sell the Collateral or any portion thereof pursuant to a judgment or decree of a court or courts having competent jurisdiction or pursuant to a proceeding by a court appointed receiver.  Any sale pursuant to the provisions of this Section 4.01 shall be deemed to conform to the commercially reasonable standards as provided in Section 9-610(b) of the New York UCC or its equivalent in other jurisdictions.

Each Grantor irrevocably makes, constitutes and appoints the Notes Collateral Agent (and all officers, employees or agents designated by the Notes Collateral Agent) as such Grantor’s true and lawful agent (and attorney-in-fact) during the continuance of an Event of Default and after notice to the Issuer of its intent to exercise such rights, for the purpose of (i) making, settling and adjusting claims in respect of Article 9 Collateral under policies of insurance, endorsing the name of such Grantor on any check, draft, instrument or other item of payment for the proceeds of such policies of insurance, (ii) making all determinations and decisions with respect thereto and (iii) obtaining or maintaining the policies of insurance required by the Collateral Documents or paying any premium in whole or in part relating thereto.  All sums disbursed by the Notes Collateral Agent in connection with this paragraph, including reasonable attorneys’ fees, court costs, expenses and other charges relating thereto, shall be payable, within 10 days of demand, by the Grantors to the Notes Collateral Agent and shall be additional Secured Obligations secured hereby.

SECTION 4.02.  Application of Proceeds.

(a)  Subject to the terms of the Intercreditor Agreement, the Notes Collateral Agent shall apply the proceeds of any collection or sale of Collateral, including any Collateral consisting of cash, as follows:

First, to pay Secured Obligations in respect of incurred and unpaid fees and expenses of the Notes Collateral Agent and the Trustee under the Notes Documents;

Second, towards payment of amounts then due and owing and remaining unpaid in respect of the Secured Obligations, pro rata among the Secured Parties according to the amounts of the Secured Obligations then due and owing and remaining unpaid to the Secured Parties.

Third, towards payment of any remaining Secured Obligations, pro rata among the Secured Parties according to the amounts of the Secured Obligations then held by the Secured Parties; and

Last, any balance remaining after the Secured Obligations shall have been paid in full shall be paid over to the Issuer or to whomsoever may be lawfully entitled to receive the same.

20

The Notes Collateral Agent shall have absolute discretion as to the time of application of any such proceeds, moneys or balances in accordance with this Agreement.  Upon any sale of Collateral by the Notes Collateral Agent (including pursuant to a power of sale granted by statute or under a judicial proceeding), the receipt of the Notes Collateral Agent or of the officer making the sale shall be a sufficient discharge to the purchaser or purchasers of the Collateral so sold and such purchaser or purchasers shall not be obligated to see to the application of any part of the purchase money paid over to the Notes Collateral Agent or such officer or be answerable in any way for the misapplication thereof.

(b)  In making the determinations and allocations required by this Section 4.02, the Notes Collateral Agent may conclusively rely upon information supplied by the Trustee as to the amounts of unpaid principal and interest and other amounts outstanding with respect to the Secured Obligations, and the Notes Collateral Agent shall have no liability to any of the Secured Parties for actions taken in reliance on such information, provided that nothing in this sentence shall prevent any Grantor from contesting any amounts claimed by any Secured Party in any information so supplied.  All distributions made by the Notes Collateral Agent pursuant to this Section 4.02 shall be (subject to any decree of any court of competent jurisdiction) final (absent manifest error), and the Notes Collateral Agent shall have no duty to inquire as to the application by the Trustee of any amounts distributed to it.

ARTICLE V

Indemnity, Subrogation and Subordination

SECTION 5.01.  Indemnity.  In addition to all such rights of indemnity and subrogation as the Grantors may have under applicable law (but subject to Section 5.03), the Issuer agrees that, in the event any assets of any Grantor shall be sold pursuant to this Agreement or any other Collateral Document relating to the Notes to satisfy in whole or in part an Obligation owed to any Secured Party, the Issuer shall indemnify such Grantor in an amount equal to the greater of the book value or the fair market value of the assets so sold.

SECTION 5.02.  Contribution and Subrogation.  Each Grantor (a “Contributing Party”) agrees (subject to Section 5.03) that, in the event assets of any other Grantor shall be sold pursuant to any Collateral Document relating to the Notes to satisfy any Secured Obligation owed to any Secured Party, and such other Grantor (the “Claiming Party”) shall not have been fully indemnified by the Issuer as provided in Section 5.01, the Contributing Party shall indemnify the Claiming Party in an amount equal to the greater of the book value or the fair market value of such assets, in each case multiplied by a fraction of which the numerator shall be the net worth of the Contributing Party on the date hereof and the denominator shall be the aggregate net worth of all the Contributing Parties together with the net worth of the Claiming Party on the date hereof (or, in the case of any Grantor becoming a party hereto pursuant to Section 6.14, the date of the Security Agreement Supplement hereto executed and delivered by such

21

Grantor).  Any Contributing Party making any payment to a Claiming Party pursuant to this Section 5.02 shall be subrogated to the rights of such Claiming Party to the extent of such payment.

SECTION 5.03.  Subordination.

(a)  Notwithstanding any provision of this Agreement to the contrary, all rights of the Grantors under Sections 5.01 and 5.02 and all other rights of indemnity, contribution or subrogation under applicable law or otherwise shall be fully subordinated to the indefeasible payment in full in cash of the Secured Obligations.  No failure on the part of the Issuer or any Grantor to make the payments required by Sections 5.01 and 5.02 (or any other payments required under applicable law or otherwise) shall in any respect limit the obligations and liabilities of any Grantor with respect to its obligations hereunder, and each Grantor shall remain liable for the full amount of the obligations of such Grantor hereunder.

(b)  Each Grantor hereby agrees that upon the occurrence and during the continuance of an Event of Default and after notice from the Notes Collateral Agent all Indebtedness owed by it to any Subsidiary shall be fully subordinated to the indefeasible payment in full in cash of the Secured Obligations.

ARTICLE VI

SECTION 6.02.  Waivers; Amendment.

(a)  No failure or delay by the Notes Collateral Agent or any Secured Party in exercising any right or power hereunder or under any other Notes Document shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power.  The rights and remedies of the Notes Collateral Agent and the Secured Parties hereunder and under the other Notes Documents are cumulative and are not exclusive of any rights or remedies that they would otherwise have.  No waiver of any provision of this Agreement or consent to any departure by any Grantor therefrom shall in any event be effective unless the same shall be permitted by paragraph (b) of this Section 6.02, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given.  Without limiting the generality of the foregoing, the issuance of any Additional First Lien Debt shall not be construed as a waiver of any Default, regardless of whether the Notes Collateral Agent or any Secured Party may have had notice or knowledge of such Default at the time.  No notice or demand on any Grantor in any case shall entitle any Grantor to any other or further notice or demand in similar or other circumstances.

(b)  Subject to the terms of the Intercreditor Agreement and except as otherwise provided in the Indenture, neither this Agreement nor any provision hereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Notes Collateral Agent and the Grantor or Grantors with respect to which such waiver, amendment or modification is to apply, subject to any consent required in accordance with Section 9.02 of the Indenture.

SECTION 6.03.  Notes Collateral Agent’s Fees and Expenses.

(a)  The parties hereto agree that the Notes Collateral Agent shall be entitled to reimbursement of its expenses incurred hereunder.  Without limitation of its indemnification obligations under the other Notes Documents, the Issuer agrees to indemnify the Notes Collateral Agent and the other Indemnitees against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses, including the reasonable fees, charges and disbursements of any counsel for any Indemnitee, incurred by or asserted against any Indemnitee arising out of, in connection with, or as a result of, the execution, delivery or performance of this Agreement or any claim, litigation, investigation or proceeding relating to any of the foregoing agreement or instrument contemplated hereby, or to the Collateral, whether or not any Indemnitee is a party thereto; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that such liabilities, obligations, losses, damages, penalties, claims, demands, actions, judgments, suits, costs, expenses or disbursements resulted from the gross negligence or willful misconduct of such Indemnitee or of any Affiliate, director, officer, employee, counsel, agent or attorney-in-fact of such Indemnitee.

23

(b)  Any such amounts payable as provided hereunder shall be additional Secured Obligations secured hereby and by the other Collateral Documents relating to the Notes.  The provisions of this Section 6.03 shall remain operative and in full force and effect regardless of the termination of this Agreement or any other Notes Document, the consummation of the transactions contemplated hereby, the repayment of any of the Secured Obligations, the invalidity or unenforceability of any term or provision of this Agreement or any other Notes Document, or any investigation made by or on behalf of the Notes Collateral Agent or any other Secured Party.  All amounts due under this Section 6.03 shall be payable within 10 days of written demand therefor.

SECTION 6.04.  Successors and Assigns.  Whenever in this Agreement any of the parties hereto is referred to, such reference shall be deemed to include the permitted successors and assigns of such party; and all covenants, promises and agreements by or on behalf of any Grantor or the Notes Collateral Agent that are contained in this Agreement shall bind and inure to the benefit of their respective successors and assigns.

SECTION 6.05.  Survival of Agreement.  All covenants, agreements, representations and warranties made by the Grantors in the Notes Documents and in the certificates or other instruments prepared or delivered in connection with or pursuant to this Agreement or any other Notes Document shall be considered to have been relied upon by the Secured Parties and shall survive the execution and delivery of the Notes Documents and the issuance of any Additional First Lien Debt, regardless of any investigation made by any Secured Party or on its behalf and notwithstanding that the Notes Collateral Agent or any Secured Party may have had notice or knowledge of any Default or incorrect representation or warranty at the time any securities are issued under the Indenture, and shall continue in full force and effect as long as the principal of or any accrued interest on any Note is outstanding and unpaid.

SECTION 6.06.  Counterparts; Effectiveness; Several Agreement.  This Agreement may be executed in counterparts, each of which shall constitute an original but all of which when taken together shall constitute a single contract.  Delivery of an executed signature page to this Agreement by facsimile transmission or other electronic communication shall be as effective as delivery of a manually signed counterpart of this Agreement.  This Agreement shall become effective as to any Grantor when a counterpart hereof executed on behalf of such Grantor shall have been delivered to the Notes Collateral Agent and a counterpart hereof shall have been executed on behalf of the Notes Collateral Agent, and thereafter shall be binding upon such Grantor and the Notes Collateral Agent and their respective permitted successors and assigns, and shall inure to the benefit of such Grantor, the Notes Collateral Agent and the other Secured Parties and their respective successors and assigns, except that no Grantor shall have the right to assign or transfer its rights or obligations hereunder or any interest herein or in the Collateral (and any such assignment or transfer shall be void) except as expressly contemplated by this Agreement or the Indenture.  This Agreement shall be construed as a separate agreement with respect to each Grantor and may be

24

amended, modified, supplemented, waived or released with respect to any Grantor without the approval of any other Grantor and without affecting the obligations of any other Grantor hereunder.

SECTION 6.07.  Severability.  Any provision of this Agreement held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.  The parties shall endeavor in good faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions.

SECTION 6.08.  Right of Set-Off.  Subject to the terms of the Intercreditor Agreement, in addition to any rights and remedies of the Secured Parties provided by Law, upon the occurrence and during the continuance of any Event of Default, each Secured Party and its Affiliates is authorized at any time and from time to time, without prior notice to the Issuer or any other Grantor, any such notice being waived by the Issuer (on its own behalf and on behalf of each Grantor and its Subsidiaries) to the fullest extent permitted by applicable Law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held by, and other Indebtedness at any time owing by, such Secured Party and its Affiliates, as the case may be, to or for the credit or the account of the respective Grantors and their Subsidiaries against any and all Secured Obligations owing to such Secured Party and its Affiliates hereunder or under any other Notes Document, now or hereafter existing, irrespective of whether or not such Secured Party or Affiliate shall have made demand under this Agreement or any other Notes Document and although such Secured Obligations may be contingent or unmatured or denominated in a currency different from that of the applicable deposit or Indebtedness.  Each Secured Party agrees promptly to notify the Issuer and the Trustee after any such set off and application made by such Secured Party; provided that the failure to give such notice shall not affect the validity of such setoff and application.  The rights of the Trustee and each Secured Party under this Section 6.08 are in addition to other rights and remedies (including other rights of setoff) that the Trustee and such Secured Party may have.

SECTION 6.12.  Security Interest Absolute.  All rights of the Notes Collateral Agent hereunder, the Security Interest, the grant of a security interest in the Pledged Collateral and all obligations of each Grantor hereunder shall be absolute and unconditional irrespective of (a) any lack of validity or enforceability of the Indenture, any other Notes Document, any agreement with respect to any of the Secured Obligations or any other agreement or instrument relating to any of the foregoing, (b) any change in the time, manner or place of payment of, or in any other term of, all or any of the Secured Obligations, or any other amendment or waiver of or any consent to any departure from the Indenture, any other Notes Document or any other agreement or instrument, (c) any exchange, release or non-perfection of any Lien on other collateral, or any release or amendment or waiver of or consent under or departure from any guarantee, securing or guaranteeing all or any of the Secured Obligations or (d) any other circumstance that might otherwise constitute a defense available to, or a discharge of, any Grantor in respect of the Secured Obligations or this Agreement.

SECTION 6.13.  Termination or Release.

(a)  This Agreement, the Security Interest and all other security interests granted hereby shall terminate with respect to all Secured Obligations (other than (x) obligations under Secured Hedge Agreements not yet due and payable, (y) Cash Management Obligations not yet due and payable and (z) contingent indemnification obligations not yet accrued and payable) when all the outstanding Secured Obligations have been indefeasibly paid in full.

(b)  A Grantor shall automatically be released from its obligations hereunder and the Security Interest in the Collateral of such Grantor shall be automatically released upon the consummation of any transaction permitted by the Indenture as a result of which such Grantor ceases to be a Subsidiary or is designated as an Unrestricted Subsidiary of Holdings III; provided that Holders of more than 50% in principal amount of the total outstanding Notes shall have consented to such transaction (to the extent required by the Indenture) and the terms of such consent did not provide otherwise.

(c)  Upon any sale or other transfer by any Grantor of any Collateral that is permitted under the Indenture, or upon the effectiveness of any written consent to the release of the security interest granted hereby in any Collateral pursuant to Section 11.02 of the Indenture, the security interest of such Grantor in such Collateral shall be automatically released.

(d)  A Grantor (other than Holdings V and the Issuer) shall automatically be released from its obligations hereunder and the Security Interest in the Collateral of such Grantor shall be automatically released if such Grantor ceases to be a Material Domestic Subsidiary.

(e)  If the security interest on any Collateral is released pursuant to Section 2.04 of the Intercreditor Agreement and such release results in the release of the security

27

interest on such Collateral under this Agreement or any Collateral Document relating to the Notes, the security interest on such Collateral granted hereunder or under any such Collateral Document relating to the Notes shall be automatically released.

(f)  In connection with any termination or release pursuant to paragraph (a), (b), (c) or (e) of this Section 6.13, the Notes Collateral Agent shall execute and deliver to any Grantor, at such Grantor’s expense, all documents that such Grantor shall reasonably request to evidence such termination or release.  Any execution and delivery of documents pursuant to this Section 6.13 shall be without recourse to or warranty by the Notes Collateral Agent.

(g)  In the event that any of the Collateral shall be transferred by any Grantor in connection with the Foreign Reorganization, the security interest granted hereunder on such Collateral shall automatically be discharged and released and all rights to such Collateral shall revert to the applicable Grantor without any further action by the Notes Collateral Agent or any other Person.  Without prejudice to the foregoing, upon the request of the applicable Grantor, the Notes Collateral Agent, at the expense of such Grantor, shall promptly execute and deliver to such Grantor, all releases, termination statements, stock certificates, any certificated securities or any other documents necessary or desirable for the release of the security interest on such Collateral.

(h)  Notwithstanding anything to the contrary set forth herein or in any other Notes Document, so long as no Default or Event of Default shall have occurred and be continuing, in the event that the Foreign Reorganization is not consummated and to the extent that any Permitted Intercompany Transfer has occurred (or will occur concurrently with such release described in the Indenture), any security interests granted hereunder by Holdings IV on any Collateral shall automatically be discharged and released without any further action by the Notes Collateral Agent or any other Person.  Subject to the terms of the Intercreditor Agreement, in connection with the foregoing, upon the request of the Issuer, the Notes Collateral Agent, at the expense of Issuer, shall promptly execute and deliver to Holdings IV, Holdings V or SigmaTel, as applicable, all releases, termination statements, stock certificates, any certificated securities or any other documents necessary or desirable for the release of the security interest on such Collateral.

28

SECTION 6.15.  Notes Collateral Agent Appointed Attorney-in-Fact.  Each Grantor hereby appoints the Notes Collateral Agent the attorney-in-fact of such Grantor for the purpose of carrying out the provisions of this Agreement and taking any action and executing any instrument that the Notes Collateral Agent may deem necessary or advisable to accomplish the purposes hereof at any time after and during the continuance of an Event of Default, which appointment is irrevocable (until termination of the Indenture) and coupled with an interest.  Without limiting the generality of the foregoing, the Notes Collateral Agent shall have the right, upon the occurrence and during the continuance of an Event of Default and notice by the Notes Collateral Agent to the Issuer of its intent to exercise such rights, with full power of substitution either in the Notes Collateral Agent’s name or in the name of such Grantor (a) to receive, endorse, assign and/or deliver any and all notes, acceptances, checks, drafts, money orders or other evidences of payment relating to the Collateral or any part thereof; (b) to demand, collect, receive payment of, give receipt for and give discharges and releases of all or any of the Collateral; (c) to sign the name of any Grantor on any invoice or ▇▇▇▇ of lading relating to any of the Collateral; (d) to send verifications of Accounts Receivable to any Account Debtor; (e) to commence and prosecute any and all suits, actions or proceedings at law or in equity in any court of competent jurisdiction to collect or otherwise realize on all or any of the Collateral or to enforce any rights in respect of any Collateral; (f) to settle, compromise, compound, adjust or defend any actions, suits or proceedings relating to all or any of the Collateral; (g) to notify, or to require any Grantor to notify, Account Debtors to make payment directly to the Notes Collateral Agent; and (h) to use, sell, assign, transfer, pledge, make any agreement with respect to or otherwise deal with all or any of the Collateral, and to do all other acts and things necessary to carry out the purposes of this Agreement, as fully and completely as though the Notes Collateral Agent were the absolute owner of the Collateral for all purposes; provided that nothing herein contained shall be construed as requiring or obligating the Notes Collateral Agent to make any commitment or to make any inquiry as to the nature or sufficiency of any payment received by the Notes Collateral Agent, or to present or file any claim or notice, or to take any action with respect to the Collateral or any part thereof or the moneys due or to become due in respect thereof or any property covered thereby.  The Notes Collateral Agent and the other Secured Parties shall be accountable only for amounts actually received as a result of the exercise of the powers granted to them herein, and neither they nor their officers, directors, employees or agents shall be responsible to any Grantor for any act or failure to act hereunder, except for their own gross negligence or willful misconduct or that of any of their Affiliates, directors, officers, employees, counsel, agents or attorneys-in-fact.

SECTION 6.16.  General Authority of the Notes Collateral Agent.  By acceptance of the benefits of this Agreement and any other Collateral Documents relating to the Notes, each Secured Party (whether or not a signatory hereto) shall be deemed irrevocably (a) to consent to the appointment of the Notes Collateral Agent as its agent hereunder and under such other Collateral Documents relating to the Notes, (b) to confirm that the Notes Collateral Agent

29

shall have the authority to act as the exclusive agent of such Secured Party for the enforcement of any provisions of this Agreement and such other Collateral Documents relating to the Notes against any Grantor, the exercise of remedies hereunder or thereunder and the giving or withholding of any consent or approval hereunder or thereunder relating to any Collateral or any Grantor’s obligations with respect thereto, (c) to agree that it shall not take any action to enforce any provisions of this Agreement or any other Collateral Document relating to the Notes against any Grantor, to exercise any remedy hereunder or thereunder or to give any consents or approvals hereunder or thereunder except as expressly provided in this Agreement or any other Collateral Document relating to the Notes and (d) to agree to be bound by the terms of this Agreement and any other Collateral Documents relating to the Notes.

Accordingly, the Notes Collateral Agent and the New Subsidiary agree as follows:

SECTION 1.  In accordance with Section 6.14 of the Collateral Agreement, the New Subsidiary by its signature below becomes a Grantor under the Security Agreement with the same force and effect as if originally named therein as a Grantor and the New Subsidiary hereby (a) agrees to all the terms and provisions of the Security Agreement applicable to it as a Grantor thereunder and (b) represents and warrants that the representations and warranties made by it as a Grantor thereunder are true and correct on and as of the date hereof.  In furtherance of the foregoing, the New Subsidiary, as security for the payment and performance in full of the Secured Obligations does hereby create and grant to the Notes Collateral Agent, its successors and assigns, for the benefit of the Secured Parties, their successors and assigns, a security interest in and lien on all of the New Subsidiary’s right, title and interest in and to the Collateral (as defined in the Security Agreement) of the New Subsidiary.  Each reference

SECTION 2.  The New Subsidiary represents and warrants to the Notes Collateral Agent and the other Secured Parties that this Supplement has been duly authorized, executed and delivered by it and constitutes its legal, valid and binding obligation, enforceable against it in accordance with its terms, except as such enforceability may be limited by Debtor Relief Laws and by general principles of equity.

SECTION 3.  This Supplement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract.

The parties hereto shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions.

SECTION 8.  All communications and notices hereunder shall be in writing and given as provided in Section 6.01 of the Security Agreement.
