(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 as of the Issue Date.

(c) Schedule III hereto sets forth, as of the date hereof, for each Grantor, (i) all United States registered Patents and Patent applications owned by such Grantor, including the name of the registered owner, type, registration or application number and the expiration date (if already registered) thereof, (ii) all United States registered Trademarks and Trademark applications owned by such Grantor, including the name of the registered owner, the registration or application number and the expiration date (if already registered) thereof, and (iii) all United States registered Copyrights and Copyright applications owned by such Grantor, including the name of the registered owner, title and, if applicable, the registration number of each such Copyright or Copyright application.

13

(d) Schedule IV hereto sets forth, as of the date hereof, each Commercial Tort Claim in respect of which a complaint or a counterclaim has been filed by any Grantor seeking damages in an amount of US$1,000,000 or more.

(e) The Security Interest constitutes (i) a legal and valid security interest in all the Article 9 Collateral securing the payment and performance of the Notes Obligations, (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 and (iii) a security interest that shall be perfected in all Article 9 Collateral in which a security interest may be perfected upon the receipt and recording of the IP Security Agreements with the United States Patent and Trademark Office and the United States Copyright Office. The Security Interest is and shall be prior to any other Lien on any of the Article 9 Collateral, other than Permitted Liens expressly permitted to be prior to the Security Interest under the Indenture.

(f) The Article 9 Collateral is owned by the Grantors free and clear of any Lien, except for Permitted Liens. None of the Grantors has filed or consented to the filing of (i) any financing statement or analogous document under the Uniform Commercial Code or any other applicable laws covering any Article 9 Collateral, (ii) any assignment in which any Grantor assigns any Collateral or any security agreement or similar instrument covering any Article 9 Collateral with the United States Patent and Trademark Office or the United States Copyright Office or (iii) 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 Permitted Liens.

SECTION 3.03. Covenants. (a)  Symmetry and the Company will furnish to the Collateral Agent promptly (and, in any event, within 15 days of the occurrence of any such change) written notice of any change (i) in any Grantor’s legal name, as set forth in its documents or organization, (ii) in the location of any Grantor’s chief executive office, (iii) in any Grantor’s form of organization or corporate structure (including as a result of any merger or consolidation), (iv) in any Grantor’s Federal Taxpayer Identification Number or identification number, if any, issued to it by the jurisdiction of its organization or (v) in the jurisdiction of any Grantor’s organization.

(b)  Each Grantor agrees to maintain, at its own cost and expense, complete and accurate records with respect to the Article 9 Collateral owned by it, and in which it has granted a security interest hereunder, in accordance with GAAP and applicable law, and, at such time or times as the Collateral Agent may reasonably request, promptly to prepare and deliver to the Collateral Agent a duly certified schedule or schedules in form and detail satisfactory to the Collateral Agent showing the identity, amount and location of any and all such Article 9 Collateral.

14

(c)  Within 90 days after the end of each fiscal year of Symmetry, the Company will furnish to the Collateral Agent an Officers’ Certificate setting forth (i) any Capital Stock or Indebtedness owned by any Grantor, (ii) any Intellectual Property owned by any Grantor and (iii) any Commercial Tort Claims in respect of which a complaint or a counterclaim has been filed by any Grantor and that, in each case, (A) if so owned or filed by a Grantor as of the Issue Date, would have been required to be set forth on the applicable schedule to this Agreement pursuant to the terms hereof and (B) have not been set forth on any such schedule to this Agreement or in a certificate previously delivered pursuant to this paragraph.

(d)  Each Grantor shall, at its own expense, take any and all actions necessary to defend title to the Article 9 Collateral in which it has granted a security interest hereunder against all Persons and to defend the Security Interest of the Collateral Agent in such Article 9 Collateral and the priority thereof against any Lien, other than Permitted Liens.

(e)  Each Grantor agrees, 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 may be required by applicable law or as the Collateral Agent (acting in accordance with Section 7.01(b)) may from time to time reasonably request to better assure, preserve, protect and perfect 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.

Without limiting the generality of the foregoing, each Grantor hereby authorizes the Collateral Agent, with prompt notice thereof to the Grantors, to supplement this Agreement by supplementing Schedule III or adding additional schedules hereto to specifically identify any asset or item that may constitute Copyrights, Licenses, Patents or Trademarks; provided that any Grantor shall have the right, exercisable within 10 days after it has been notified by the Collateral Agent of the specific identification of such Collateral, to advise the Collateral Agent in writing of any inaccuracy of the representations and warranties made by such Grantor hereunder with respect to such Collateral. Each Grantor agrees that it will use its best efforts to take such action as shall be necessary in order that all representations and warranties hereunder shall be true and correct with respect to such Collateral within 30 days after the date it has been notified by the Collateral Agent of the specific identification of such Collateral.

(f)  The Collateral Agent and such Persons as the Collateral Agent may reasonably designate shall have the right, at the Grantors’ own cost and expense, upon reasonable prior notice, to inspect the Article 9 Collateral subject to the Security Interest, all records related thereto (and to make extracts and copies from such records) and the premises upon which any of such Article 9 Collateral is located, to discuss the Grantors’ affairs, finances and condition with the officers of the Grantors and their independent accountants and to verify under reasonable procedures the validity, amount, quality, quantity, value, condition and status of, or any other matter relating to, the Article 9

15

Collateral subject to the Security Interest (including, in the case of Accounts or Article 9 Collateral in the possession of any third person, by contacting Account Debtors or the third person possessing such Article 9 Collateral for the purpose of making such a verification), all at such reasonable times and as often as reasonably requested. The Collateral Agent shall have the absolute right to share any information it gains from such inspection or verification with any other Secured Party.

(g)  At its option, the Collateral Agent may discharge past due taxes, assessments, charges, fees or Liens at any time levied or placed on the Article 9 Collateral (other than Permitted Liens), and may pay for the maintenance and preservation of the Article 9 Collateral subject to the Security Interest to the extent any Grantor fails to do so as required by the Indenture or this Agreement, and each Grantor jointly and severally agrees to reimburse the Collateral Agent on demand for any payment made or any expense incurred by the Collateral Agent pursuant to the foregoing authorization; provided that nothing in this paragraph shall be interpreted as excusing any Grantor from the performance of, or imposing any obligation on the Collateral Agent or any other Secured Party to cure or perform, any covenants or other promises of any Grantor with respect to taxes, assessments, charges, fees or Liens and maintenance of properties as set forth herein or in the other Notes Documents.

(h)  If at any time any Grantor shall take a security interest in any property of an Account Debtor or any other Person to secure payment and performance of an Account, such Grantor shall promptly assign such security interest to the 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.

(i)  Each Grantor shall remain liable 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 subject to the Security Interest, all in accordance with the terms and conditions thereof, and each Grantor jointly and severally agrees to indemnify and hold harmless the Collateral Agent and the other Secured Parties from and against any and all liability for such performance.

(j)  Each of the Grantors will maintain, with financially sound and reputable insurance companies, insurance in such amounts (with no greater risk retention) and against such risks as are customarily maintained by companies of established repute engaged in the same or similar businesses operating in the same or similar locations. Each such policy of insurance maintained by Grantors (other than policies of the type in respect of which such actions customarily are not required) shall (i) in the case of each liability insurance policy, name the Collateral Agent, on behalf of the Secured Parties, as an additional insured thereunder, (ii) in the case of each casualty insurance policy, contain a loss payable clause or endorsement that names the Collateral Agent, on behalf of the Secured Parties, as the loss payee thereunder and (iii) provide for at least 30 days’ (or such shorter number of days may be agreed to by the Collateral Agent) prior written notice to the Collateral Agent of any cancellation of such policy. Upon the Collateral

16

Agent’s request, Symmetry and the Company will furnish to the Collateral Agent information in reasonable detail as to the insurance so maintained. Each Grantor irrevocably makes, constitutes and appoints the Collateral Agent (and all officers, employees or agents designated by the Collateral Agent) as such Grantor’s true and lawful agent (and attorney-in-fact) for the purpose, during the continuance of an Event of Default, of making, settling and adjusting claims in respect of Article 9 Collateral subject to the Security Interest 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 and for making all determinations and decisions with respect thereto. All sums disbursed by the Collateral Agent in connection with this paragraph, including reasonable attorneys’ fees, court costs, expenses and other charges relating thereto, shall be payable, upon demand, by the Grantors to the Collateral Agent and shall be additional Obligations secured hereby.

(k)  Each Grantor shall maintain, in customary form and manner, records of its Chattel Paper and its books, records and documents evidencing or pertaining thereto.

SECTION 3.04. Other Actions. In order to further ensure the attachment, perfection and priority of, and the ability of the 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 owned by it and subject to the Security Interest:

(a) Instruments. If any Grantor shall at any time hold or acquire any Instruments subject to the Security Interest, such Grantor shall forthwith endorse, assign and deliver the same to the Collateral Agent, accompanied by such instruments of transfer or assignment duly executed in blank as the Collateral Agent may from time to time reasonably request.

(b) Deposit Accounts. Each Grantor shall use its commercially reasonable efforts, for each Deposit Account that such Grantor at any time opens or maintains (other than payroll and ▇▇▇▇▇ cash accounts, the aggregate amount on deposit in all of which accounts does not exceed US$1,000,000 at any time), to cause the depositary bank to execute and deliver to the Collateral Agent a Deposit Account Control Agreement with respect to such Deposit Account.

(c) Investment Property. Except to the extent otherwise provided in Article III, if any Grantor shall at any time hold or acquire any certificated securities subject to the Security Interest, such Grantor shall forthwith endorse, assign and deliver the same to the Collateral Agent, accompanied by such instruments of transfer or assignment duly executed in blank as the Collateral Agent may from time to time specify. If any securities now or hereafter acquired by any Grantor and subject to the Security Interest are uncertificated and are issued to such Grantor or its nominee directly by the issuer thereof, such Grantor shall promptly notify the Collateral Agent thereof and, at the Collateral Agent’s request and option (made in accordance with Section 7.01(b)), pursuant to an

17

agreement customary in form and substance, either (i) cause the issuer to agree to comply with instructions from the Collateral Agent as to such securities, without further consent of any Grantor or such nominee, or (ii) arrange for the Collateral Agent to become the registered owner of the securities. If any securities, whether certificated or uncertificated, or other investment property now or hereafter acquired by any Grantor and subject to the Security Interest are held by such Grantor or its nominee through a securities intermediary or commodity intermediary, such Grantor shall promptly notify the Collateral Agent thereof and, at the Collateral Agent’s request and option (made in accordance with Section 7.01(b)), pursuant to an agreement customary in form and substance, either (i) cause such securities intermediary or commodity intermediary, as the case may be, to agree to comply with entitlement orders or other instructions from the 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 Collateral Agent to such commodity intermediary, in each case without further consent of any Grantor or such nominee, or (ii) in the case of Investment Property held through a securities intermediary, arrange for the Collateral Agent to become the entitlement holder with respect to such investment property, with the Grantor being permitted, only with the consent of the Collateral Agent, to exercise rights to withdraw or otherwise deal with such investment property. The Collateral Agent agrees with each of the Grantors that the 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 or, after giving effect to any such investment and withdrawal rights, would occur. The provisions of this paragraph shall not apply to any financial assets credited to a securities account for which the Collateral Agent is the securities intermediary.

(d) Electronic Chattel Paper and Transferable Records. If any Grantor at any time holds or acquires an interest in any electronic chattel paper or any “transferable record,” as that term is defined in Section 201 of the Federal Electronic Signatures in Global and National Commerce Act, or in Section 16 of the Uniform Electronic Transactions Act as in effect in any relevant jurisdiction, such Grantor shall promptly notify the Collateral Agent thereof and, at the request of the Collateral Agent, shall take such action as the Collateral Agent may reasonably request (acting in accordance with Section 7.01(b)) to vest in the Collateral Agent control under New York UCC Section 9-105 of such electronic chattel paper or control under Section 201 of the Federal Electronic Signatures in Global and National Commerce Act or, as the case may be, Section 16 of the Uniform Electronic Transactions Act, as so in effect in such jurisdiction, of such transferable record. The Collateral Agent agrees with such Grantor that the Collateral Agent will arrange, pursuant to customary procedures and so long as such procedures will not result in the Collateral Agent’s loss of control, for the Grantor to make alterations to the electronic chattel paper or transferable record permitted under UCC Section 9-105 or, as the case may be, Section 201 of the

18

Federal Electronic Signatures in Global and National Commerce Act or Section 16 of the Uniform Electronic Transactions Act for a party in control to allow without loss of control, unless an Event of Default has occurred and is continuing or would occur after taking into account any action by such Grantor with respect to such electronic chattel paper or transferable record.

(e) Letter-of-Credit Rights. If any Grantor is at any time a beneficiary under a letter of credit now or hereafter issued in favor of such Grantor, the rights under which are subject to the Security Interest, such Grantor shall promptly notify the Collateral Agent thereof and, at the request and option of the Collateral Agent (made in accordance with Section 7.01(b)), such Grantor shall, pursuant to an agreement customary in form and substance, either (i) arrange for the issuer and any confirmer of such letter of credit to consent to an assignment to the Collateral Agent of the proceeds of any drawing under the letter of credit or (ii) arrange for the Collateral Agent to become the transferee beneficiary of the letter of credit, with the Collateral Agent agreeing, in each case, that the proceeds of any drawing under the letter of credit are to be paid to the applicable Grantor unless an Event of Default has occurred or is continuing.

(f) Commercial Tort Claims. If any Grantor shall at any time hold or acquire a commercial tort claim in an amount reasonably estimated to exceed US$1,000,000, such Grantor shall promptly notify the Collateral Agent thereof in a writing signed by such Grantor including a summary description of such claim and grant to the Collateral Agent in such writing a security interest therein and in the proceeds thereof, all upon the terms of this Agreement, with such writing to be customary in form and substance.

(g) Collateral Access Agreements. Each Grantor shall use commercially reasonable efforts to obtain a Collateral Access Agreement from the lessor of each leased property, mortgagee of owned property or bailee or consignee with respect to any warehouse, processor or converter facility or other location where Collateral is stored or located, which agreement or letter shall provide access rights and contain a waiver or subordination of all Liens or claims that the landlord, mortgagee, bailee or consignee may assert against the Collateral at that location. Each Grantor shall timely and fully pay and perform its obligations under all leases and other agreements with respect to each leased location or third party warehouse where any Collateral is or may be located.

SECTION 3.05. Covenants Regarding Patent, Trademark and Copyright Collateral. (a)  Each Grantor agrees that it will not take or omit take to any action (and will exercise commercially reasonable efforts to prevent its licensees from taking or omitting to take any action) whereby any Patent that is material to the conduct of such Grantor’s business may become invalidated or dedicated to the public, and agrees that it shall continue to ▇▇▇▇ any products covered by a Patent with the relevant patent number as necessary and sufficient to establish and preserve its maximum rights under applicable patent laws.

19

(b)  Each Grantor (either itself or through its licensees or its sublicensees) will, for each Trademark material to the conduct of such Grantor’s business, (i) maintain such Trademark in full force free from any claim of abandonment or invalidity for non-use, (ii) maintain the quality of products and services offered under such Trademark, (iii) display such Trademark with notice of Federal or foreign registration to the extent necessary and sufficient to establish and preserve its maximum rights under applicable law and (iv) not knowingly use or knowingly permit the use of such Trademark in violation of any third party rights.

(c)  Each Grantor (either itself or through its licensees or sublicensees) will, for each work covered by a material Copyright, continue to publish, reproduce, display, adopt and distribute the work with appropriate copyright notice as necessary and sufficient to establish and preserve its maximum rights under applicable copyright laws.

(d)  Each Grantor shall notify the Collateral Agent promptly if it knows or has reason to know that any Patent, Trademark or Copyright material to the conduct of its business may become abandoned, lost or dedicated to the public, or of any materially adverse determination or development (including the institution of, or any such determination or development in, any proceeding in the United States Patent and Trademark Office, United States Copyright Office or any court or similar office of any country) regarding such Grantor’s ownership of any Patent, Trademark or Copyright, its right to register the same, or its right to keep and maintain the same.

(e)  In no event shall any Grantor, either itself or through any agent, employee, licensee or designee, file an application for any Patent, Trademark or Copyright (or for the registration of any Trademark or Copyright) with the United States Patent and Trademark Office, United States Copyright Office or any office or agency in any political subdivision of the United States or in any other country or any political subdivision thereof, unless it promptly informs the Collateral Agent, and, upon request of the Collateral Agent, executes and delivers any and all IP Security Agreements and other instruments, documents and papers as the Collateral Agent may reasonably request (acting in accordance with Section 7.01(b)) to evidence the Collateral Agent’s security interest in such Patent, Trademark or Copyright, and each Grantor hereby appoints the Collateral Agent as its attorney-in-fact to execute and file such writings for the foregoing purposes, all acts of such attorney being hereby ratified and confirmed; such power, being coupled with an interest, is irrevocable.

(f)  Each Grantor will take all necessary steps that are consistent with the practice in any proceeding before the United States Patent and Trademark Office, United States Copyright Office or any office or agency in any political subdivision of the United States or in any other country or any political subdivision thereof, to maintain and pursue each material application relating to the Patents, Trademarks or Copyrights (and to obtain the relevant grant or registration) and to maintain each issued Patent and each registration of the Trademarks and Copyrights that is material to the conduct of any Grantor’s business, including timely filings of applications for renewal, affidavits of use, affidavits of incontestability and payment of maintenance fees, and, if consistent with good

20

business judgment, to initiate opposition, interference and cancelation proceedings against third parties.

(g)  In the event that any Grantor has reason to believe that any Article 9 Collateral consisting of a Patent, Trademark or Copyright material to the conduct of any Grantor’s business has been or is about to be infringed, misappropriated or diluted by a third party, such Grantor promptly shall notify the Collateral Agent and shall, if consistent with good business judgment, promptly ▇▇▇ for infringement, misappropriation or dilution and to recover any and all damages for such infringement, misappropriation or dilution, and take such other actions as are appropriate under the circumstances to protect such Article 9 Collateral.

(h)  Upon and during the continuance of an Event of Default, each Grantor shall use its commercially reasonable efforts to obtain all requisite consents or approvals by the licensor of each Copyright License, Patent License or Trademark License to effect the assignment of all such Grantor’s right, title and interest thereunder to the Collateral Agent or its designee.

ARTICLE IV

Remedies

SECTION 4.01. Remedies Upon Default. Upon the occurrence and during the continuance of an Event of Default, each Grantor agrees to deliver each item of Collateral to the Collateral Agent on demand, and it is agreed that the Collateral Agent shall have the right to take any of or all the following actions at the same or different times:  (a) with respect to any Article 9 Collateral consisting of Intellectual Property, on demand, to cause the Security Interest to become an assignment, transfer and conveyance of any of or all such Article 9 Collateral by the applicable Grantors to the Collateral Agent, or to license or sublicense, whether general, special or otherwise, and whether on an exclusive or nonexclusive basis, any such Article 9 Collateral throughout the world on such terms and conditions and in such manner as the Collateral Agent shall determine (other than in violation of any then-existing licensing arrangements to the extent that waivers cannot be obtained), and (b) with or without legal process and with or without prior notice or demand for performance, to take possession of the Article 9 Collateral and without liability for trespass to enter any premises where the Article 9 Collateral may be located for the purpose of taking possession of or removing the Article 9 Collateral and, generally, to exercise any and all rights afforded to a secured party under the Uniform Commercial Code or other applicable law. Without limiting the generality of the foregoing, each Grantor agrees that the Collateral Agent shall have the right, subject to the mandatory requirements of applicable law, to sell or otherwise dispose of all or any part of the Collateral 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 Collateral Agent shall deem appropriate. The 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

21

thereof, and upon consummation of any such sale the 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 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 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 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 Collateral Agent may (in its sole and absolute discretion) determine. The 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 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 Collateral Agent until the sale price is paid by the purchaser or purchasers thereof, but the 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 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 or any portion thereof subject thereto, notwithstanding the fact that after the Collateral Agent shall have entered into such an agreement all Events of Default shall have been remedied and the Notes Obligations paid in full. As an alternative to exercising the power of sale herein conferred upon it, the Collateral Agent may proceed by a suit or suits at law or in equity

22

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 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.

SECTION 4.02. Application of Proceeds. The Collateral Agent shall apply the proceeds of any collection or sale of any Collateral, and any Collateral consisting of cash, as follows:

FIRST, to the payment of all costs and expenses incurred by the Collateral Agent in connection with such collection or sale or otherwise in connection with this Agreement or any other Notes Document, including all court costs and the fees and expenses of its agents and legal counsel, the repayment of all advances made by the Collateral Agent hereunder or under any other Notes Document on behalf of any Grantor, any other costs or expenses incurred in connection with the exercise of any right or remedy hereunder or under any other Notes Document and any amounts due to the Collateral Agent under Section 6.03;

SECOND, to distribution to the Trustee, for application in accordance with the Indenture; and

THIRD, to the extent the Collateral Agent shall have been informed in writing by the Trustee that all Notes Obligations (other than contingent obligations) shall have been indefeasibly paid in full, to the Grantors, their successors or assigns, or as a court of competent jurisdiction may otherwise direct.

The 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 Collateral Agent (including pursuant to a power of sale granted by statute or under a judicial proceeding), the receipt of the 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 Collateral Agent or such officer or be answerable in any way for the misapplication thereof.

SECTION 4.03. Grant of License to Use Intellectual Property. For the purpose of enabling the Collateral Agent to exercise rights and remedies under this Agreement at such time as the Collateral Agent shall be lawfully entitled to exercise such rights and remedies, each Grantor hereby grants to the Collateral Agent an irrevocable, nonexclusive license (exercisable without payment of royalty or other compensation to the Grantors) to use, license or sublicense any of the Article 9 Collateral consisting of Intellectual Property now owned or hereafter acquired by such Grantor, and wherever the same may be located, and including in such license reasonable access to all media in which any of the licensed items may be recorded or stored and to all computer software

23

and programs used for the compilation or printout thereof. The rights conferred by such license may be exercised, at the option of the Collateral Agent, upon the occurrence and during the continuation of an Event of Default; provided that any license, sublicense or other transaction entered into by the Collateral Agent in accordance herewith shall be binding upon the Grantors notwithstanding any subsequent cure of an Event of Default.

SECTION 4.04. Securities Act. In view of the position of the Grantors in relation to the Pledged Collateral, or because of other current or future circumstances, a question may arise under the Securities Act, or any similar statute hereafter enacted analogous in purpose or effect (the Securities Act and any such similar statute as from time to time in effect being called the “Federal Securities Laws”) with respect to any disposition of the Pledged Collateral permitted hereunder. Each Grantor understands that compliance with the Federal Securities Laws might very strictly limit the course of conduct of the Collateral Agent if the Collateral Agent were to attempt to dispose of all or any part of the Pledged Collateral, and might also limit the extent to which or the manner in which any subsequent transferee of any Pledged Collateral could dispose of the same. Similarly, there may be other legal restrictions or limitations affecting the Collateral Agent in any attempt to dispose of all or part of the Pledged Collateral under applicable Blue Sky or other state securities laws or similar laws analogous in purpose or effect. Each Grantor recognizes that in light of such restrictions and limitations the Collateral Agent may, with respect to any sale of the Pledged Collateral, limit the purchasers to those who will agree, among other things, to acquire such Pledged Collateral for their own account, for investment, and not with a view to the distribution or resale thereof. Each Grantor acknowledges and agrees that in light of such restrictions and limitations, the Collateral Agent, in its sole and absolute discretion (a) may proceed to make such a sale whether or not a registration statement for the purpose of registering such Pledged Collateral or part thereof shall have been filed under the Federal Securities Laws and (b) may approach and negotiate with a single potential purchaser to effect such sale. Each Grantor acknowledges and agrees that any such sale might result in prices and other terms less favorable to the seller than if such sale were a public sale without such restrictions. In the event of any such sale, the Collateral Agent shall incur no responsibility or liability for selling all or any part of the Pledged Collateral at a price that the Collateral Agent, in its sole and absolute discretion, may in good ▇▇▇▇▇ ▇▇▇▇ reasonable under the circumstances, notwithstanding the possibility that a substantially higher price might have been realized if the sale were deferred until after registration as aforesaid or if more than a single purchaser were approached. The provisions of this Section will apply notwithstanding the existence of a public or private market upon which the quotations or sales prices may exceed substantially the price at which the Collateral Agent sells.

SECTION 4.05. Registration. Each Grantor agrees that, upon the occurrence and during the continuance of an Event of Default, if for any reason the Collateral Agent desires to sell any of the Pledged Collateral at a public sale, it will, at any time and from time to time, upon the written request of the Collateral Agent, use its best efforts to take or to cause the issuer of such Pledged Collateral to take such action and prepare, distribute and/or file such documents, as are required or advisable in the reasonable opinion of counsel for the Collateral Agent to permit the public sale of such

Pledged Collateral. Each Grantor further agrees to indemnify, defend and hold harmless the Collateral Agent, each other Secured Party, any underwriter and their respective officers, directors, affiliates and controlling persons from and against all loss, liability, expenses, costs of counsel (including, without limitation, reasonable fees and expenses to the Collateral Agent of legal counsel), and claims (including the costs of investigation) that they may incur insofar as such loss, liability, expense or claim arises out of or is based upon any alleged untrue statement of a material fact contained in any prospectus (or any amendment or supplement thereto) or in any notification or offering circular, or arises out of or is based upon any alleged omission to state a material fact required to be stated therein or necessary to make the statements in any thereof not misleading, except insofar as the same may have been caused by any untrue statement or omission based upon information furnished in writing to such Grantor or the issuer of such Pledged Collateral by the Collateral Agent or any other Secured Party expressly for use therein. Each Grantor further agrees, upon such written request referred to above, to use its best efforts to qualify, file or register, or cause the issuer of such Pledged Collateral to qualify, file or register, any of the Pledged Collateral under the Blue Sky or other securities laws of such states as may be requested by the Collateral Agent and keep effective, or cause to be kept effective, all such qualifications, filings or registrations. Each Grantor will bear all costs and expenses of carrying out its obligations under this Section. Each Grantor acknowledges that there is no adequate remedy at law for failure by it to comply with the provisions of this Section and that such failure would not be adequately compensable in damages, and therefore agrees that its agreements contained in this Section may be specifically enforced.

SECTION 4.06. Concerning Pledged Securities. Notwithstanding anything to the contrary contained in this Agreement or any other Notes Document, the Collateral Agent, on behalf of the Secured Parties, covenants and agrees that, to the extent that separate financial statements of any Subsidiary of Symmetry would be required by the rules of the SEC due to the fact that the Notes Obligations, or any part thereof, are secured by the Capital Stock, Intercompany Notes or other securities of such Subsidiary, it will at no time realize upon any portion of such Capital Stock, Intercompany Notes and other securities of such Subsidiary constituting Collateral with an aggregate value in excess of 19.999% of the aggregate principal amount of the Securities outstanding at such time. For purposes of this Section, the value of the Capital Stock, Intercompany Notes and other securities of any Subsidiary of Symmetry constituting Collateral at any time shall be equal to the aggregate principal amount, par value or book value of such securities as carried by the Company at such time, or the market value of such securities at such time, whichever is the greatest, as such terms are interpreted by the SEC under Rule 3-16 of Regulation S-X under the Securities Act.

Indemnity, Subrogation and Subordination

SECTION 5.01. Indemnity and Subrogation. The Company agrees that in the event any assets of any Grantor shall be sold pursuant to this Agreement or any other Security Document to satisfy in whole or in part an obligation of the Company owed to

25

any Secured Party, the Company 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 Security Document to satisfy any Notes Obligation and such other Grantor (the “Claiming Party”) shall not have been fully indemnified 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 (or, in the case of any Grantor becoming a party hereto pursuant to Section 6.13, the date of the supplement hereto executed and delivered by such Grantor) and the denominator shall be the aggregate net worth of all the Grantors (other than the Company) on the date hereof (or, in the case of any Grantor becoming a party hereto pursuant to Section 6.13, the date of the supplement hereto executed and delivered by such Grantor). Any Contributing Party making any payment to a Claiming Party pursuant to this Section shall be subrogated to the rights of such Claiming Party under Section 5.01 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 Notes Obligations. No failure on the part of 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 its obligations hereunder.

SECTION 6.02. Waivers; Amendment.

The rights and remedies of the Collateral Agent and the other 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, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. 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)  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 Collateral Agent and the Grantor or Grantors with respect to which such waiver, amendment or modification is to apply, subject to any consent required under the Indenture. The Collateral Agent shall enter into such waivers, amendments or modifications of this Agreement as it may be directed (subject to the immediately preceding sentence) to enter into by the Trustee; provided that the Collateral Agent shall not be obligated to execute any such waiver, amendment or modification that adversely affects the rights, duties, liabilities or immunities of the Collateral Agent.

(b)  Without limitation of its indemnification obligations under the other Notes Documents, each Grantor jointly and severally agrees to indemnify the Collateral Agent, its Affiliates and their respective officers, directors, employees, agents and representatives (the “Indemnitees”) against, and hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses, including the 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,

27

delivery or performance of this Agreement or any claim, litigation, investigation or proceeding relating to any of the foregoing, or any 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 losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction by final and nonappealable judgment to have resulted from the gross negligence or wilful misconduct of such Indemnitee or any of its Affiliates.

(c)  Any such amounts payable as provided hereunder shall be additional Notes Obligations secured hereby and by the other Security Documents. The provisions of this Section 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 Notes 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 Collateral Agent or any other Secured Party. All amounts due under this Section shall be payable on 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 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 this Agreement and in the certificates or other instruments prepared or delivered in connection with or pursuant to this Agreement shall be considered to have been relied upon by the Secured Parties and shall survive the execution and delivery of this Agreement, the other Notes Documents and the issuance of the Securities, regardless of any investigation made by any Secured Party or on its behalf, and shall continue in full force and effect until this Agreement shall terminate.

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 or electronic transmission 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 Collateral Agent and a counterpart hereof shall have been executed on behalf of the Collateral Agent, and thereafter shall be binding upon such Grantor and the Collateral Agent and their respective permitted successors and assigns, and shall inure to the benefit of such Grantor, the 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

28

assignment or transfer shall be void) except as expressly provided in this Agreement or the Indenture. This Agreement shall be construed as a separate agreement with respect to each Grantor and may be 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. Governing Law; Jurisdiction; Consent to Service of Process. (a)  This Agreement shall be construed in accordance with and governed by the law of the State of New York.

(b)  Each of the Grantors hereby irrevocably and unconditionally submits, for itself and its property, to the nonexclusive jurisdiction of the Supreme Court of the State of New York sitting in New York County and of the United States District Court of the Southern District of New York, and any appellate court from any thereof, in any action or proceeding arising out of or relating to this Agreement or any other Notes Document, or for recognition or enforcement of any judgment, and each of the parties hereto hereby irrevocably and unconditionally agrees that all claims in respect of any such action or proceeding may be heard and determined in such New York State or, to the extent permitted by law, in such Federal court. Each of the parties hereto agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement or any other Notes Document shall affect any right that the Collateral Agent or any other Secured Party may otherwise have to bring any action or proceeding relating to this Agreement or any other Notes Document against any Grantor, or its properties in the courts of any jurisdiction.

(c)  Each of the Grantors hereby irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so, any objection which it may now or hereafter have to the laying of venue of any suit, action or proceeding arising out of or relating to this Agreement or any other Notes Document in any court referred to in paragraph (b) of this Section.

(d)  Each party to this Agreement irrevocably consents to service of process in the manner provided for notices in Section 6.01. Nothing in this Agreement or

29

any other Notes Document will affect the right of any party to this Agreement to serve process in any other manner permitted by law.

SECTION 6.09. WAIVER OF JURY TRIAL. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT, ANY OTHER NOTES DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

SECTION 6.10. Headings. Article and Section headings and the Table of Contents used herein are for convenience of reference only, are not part of this Agreement and are not to affect the construction of, or to be taken into consideration in interpreting, this Agreement.

SECTION 6.11. Security Interest Absolute. All rights of the 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 Notes 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 Notes 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 Notes Obligations, or (d) any other circumstance that might otherwise constitute a defense available to, or a discharge of, any Grantor in respect of the Notes Obligations or this Agreement.

SECTION 6.12. Termination or Release. (a)  This Agreement, the Security Interest and all other security interests granted hereby shall terminate when all the Notes Obligations (other than contingent obligations) have been indefeasibly paid in full pursuant to the terms of the Indenture, and the Trustee shall have informed the Collateral Agent thereof in writing.

(b)  Except as provided in paragraph (a) of this Section, releases of any Grantors from their obligations hereunder, and releases of Collateral from the Liens created hereby, shall be governed by the Indenture, including Section 11.03 thereof.

30

(c)  In connection with any such termination or release pursuant to this Section, the 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; provided, however, that the Collateral Agent shall not, and shall not be required to, execute or deliver any such documents unless it shall have been directed to do so by the Trustee. Any execution and delivery of documents pursuant to this Section shall be without recourse to or warranty by the Collateral Agent.

SECTION 6.13. Additional Grantors. If, pursuant to the Indenture, Symmetry and the Restricted Subsidiaries are required to cause any Subsidiary of Symmetry to become a party to this Agreement, upon the execution and delivery by the Collateral Agent and such Subsidiary of an instrument in the form of Exhibit I hereto, such Subsidiary Party shall become a Grantor hereunder with the same force and effect as if originally named as such herein. The execution and delivery of any such instrument shall not require the consent of any other Grantor hereunder. The rights and obligations of each Grantor hereunder shall remain in full force and effect notwithstanding the addition of any new Grantor as a party to this Agreement.

SECTION 6.14. Collateral Agent Appointed Attorney-in-Fact. Each Grantor hereby appoints the 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 Collateral Agent may deem necessary or advisable to accomplish the purposes hereof, which appointment is irrevocable and coupled with an interest. Without limiting the generality of the foregoing, the Collateral Agent shall have the right, upon the occurrence and during the continuance of an Event of Default, with full power of substitution either in the Collateral Agent’s name or in the name of such Grantor (a) to receive, endorse, assign 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 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 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 Collateral Agent to make any commitment or to make any inquiry as to the nature or sufficiency of any payment received by the 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 Collateral Agent and the other Secured Parties shall be accountable only for amounts actually received as a

31

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 wilful misconduct.

SECTION 6.15. Intercreditor Agreement. Notwithstanding anything herein to the contrary, the Liens granted to the Collateral Agent under this Agreement and the exercise of the rights and remedies of the Collateral Agent hereunder are subject to the provisions of the Intercreditor Agreement. In the event of any conflict between the terms of the Intercreditor Agreement and this Agreement, the terms of the Intercreditor Agreement shall govern and control. At any time prior to the Discharge of Revolving Credit Obligations (as defined in the Intercreditor Agreement), no Grantor shall be required to take or refrain from taking any action at the request of the Collateral Agent with respect to any ABL Collateral if such action or inaction would be inconsistent with (a) any action or inaction affirmatively requested by the Credit Agent in accordance with the Credit Agreement or (b) any action or inaction affirmatively required by any of the provisions of the Credit Agreement.

ARTICLE VII

Concerning the Collateral Agent

SECTION 7.01. Confirmation of Appointment. (a) Each of the Secured Parties hereby confirms its appointment of The Bank of New York to act, and The Bank of New York hereby agrees to act, as the Collateral Agent for the Secured Parties pursuant to the terms of this Agreement and the other Security Documents, and authorizes the Collateral Agent to take such actions on its behalf and to exercise such powers as are delegated to the Collateral Agent by the terms of this Agreement and the other Security Documents, together with such actions and powers as are reasonably incidental thereto. Without limiting the generality of the foregoing, the Collateral Agent is hereby expressly authorized to execute any and all documents (including releases) with respect to the Collateral, and the rights of the Secured Parties with respect thereto, as contemplated by and in accordance with the provisions of this Agreement and the other Security Documents.

SECTION 7.02. Duties or Obligations. The Collateral Agent shall not have any duties or obligations except those expressly set forth in the Loan Documents. Without limiting the generality of the foregoing, (i) the Collateral Agent shall not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing and (ii) the Collateral Agent shall not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated by the Notes Documents that the Collateral Agent is required to exercise in writing by the Trustee (or by the Holders of at least 25% in aggregate principal amount of the Securities). The Collateral Agent shall take such actions and exercise such remedies hereunder and under the other Notes Documents as it is from time to time directed, in writing, to take or exercise by the Trustee, provided that the Collateral Agent shall not be obligated to take any such action that adversely affects the rights, duties, liabilities or immunities of the Collateral Agent. The Collateral Agent

32

shall be entitled to rely conclusively, without any independent investigation whatsoever, and shall be fully protected in so relying, on any direction, instruction or consent of the Trustee, if such direction, instruction or consent is purported to be given on behalf of the Trustee. The Collateral Agent shall not be liable for any action taken or not taken by it with the consent or at the request of the Trustee (or the Holders of at least 25% in aggregate principal amount of the Securities) or in the absence of its own gross negligence or wilful misconduct. In no event shall the Collateral Agent be liable, directly or indirectly, for any special, indirect or consequential damages, even if the Collateral Agent has been advised of the possibility of such damages.

SECTION 7.03. Reliance; Sub-Agents. (a)  The Collateral Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it to be genuine and to have been signed or sent by the proper person. The Collateral Agent may also rely upon any statement made to it orally or by telephone and believed by it to have been made by the proper person, and shall not incur any liability for relying thereon. The Collateral Agent may consult with legal counsel (who may be counsel for Symmetry), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

(b)  The Collateral Agent may perform any and all its duties and exercise its rights and powers by or through any one or more sub-agents appointed by the Collateral Agent. The Collateral Agent and any such sub-agent may perform any and all its duties and exercise its rights and powers through their officers, directors, employees, agents and representatives. The exculpatory provisions of the preceding paragraphs shall apply to any such sub-agent and to the officers, directors, employees, agents and representatives of the Collateral Agent and any such sub-agent.

SECTION 7.04. Resignation of the Collateral Agent. Subject to the appointment and acceptance of a successor Collateral Agent as provided in this paragraph, the Collateral Agent may resign at any time by notifying Symmetry and the Trustee. Upon any such resignation, the Trustee or the Holders of at least 25% in aggregate principal amount of the Securities shall have the right to appoint a successor. If no successor shall have been so appointed by the Trustee or such Holders and shall have accepted such appointment within 60 days after the retiring Collateral Agent gives notice of its resignation, then the retiring Collateral Agent may, at the expense of the Grantors, petition a court of competent jurisdiction to appoint a successor Collateral Agent, which shall be a bank with an office in New York, New York, or an Affiliate of any such bank. Upon the acceptance of its appointment as the Collateral Agent by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring Collateral Agent, and the retiring Collateral Agent shall be discharged from its duties and obligations hereunder and under the other Notes Documents. Such appointment and designation shall be full evidence of the right and authority of such successor Collateral Agent to act as Collateral Agent hereunder and under the other Notes Documents, and all Collateral, power, trusts, duties, documents, rights and authority of the retiring Collateral Agent shall rest in the successor Collateral

33

Agent, without any further deed or conveyance. The retiring Collateral Agent shall, upon request of the Trustee or the successor Collateral Agent, execute and deliver any other such instrument transferring to the successor Collateral Agent all the Collateral, properties, rights, power, trust, duties, authority and title of such retiring Collateral Agent without any representations or warranties from the retiring Collateral Agent to the successor Collateral Agent or the Secured Parties. The Grantors shall execute and deliver any and all documents, conveyances or instruments requested by the Trustee, the retiring Collateral Agent or the successor Collateral Agent to reflect such transfer to the successor Collateral Agent. After the Collateral Agent’s resignation hereunder, the provisions of this Article and Section 6.03 shall continue in effect for the benefit of such retiring Collateral Agent, its Affiliates and their related Indemnitees in respect of any actions taken or omitted to be taken by any of them while acting as the Collateral Agent.

34

IN WITNESS WHEREOF, the parties hereto have duly executed this Agreement as of the day and year first above written.

The undersigned Subsidiary of Symmetry (the “New Subsidiary”) is executing this Supplement in accordance with the requirements of the Indenture to become a “Grantor” under the Collateral Agreement.

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

SECTION 1. In accordance with Section 6.13 of the Collateral Agreement, the New Subsidiary by its signature below becomes a Subsidiary Party (and accordingly, becomes a “Grantor” under the Collateral Agreement with the same force and effect as if originally named therein as such, and the New Subsidiary hereby (a) agrees to all the terms and provisions of the Collateral Agreement applicable to it in such capacities thereunder and (b) represents and warrants to the Collateral Agent, on behalf of the Secured Parties, that the representations and warranties made by it as a Grantor under the Collateral Agreement 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 Notes Obligations pursuant to the terms of the Collateral Agreement, does hereby create and grant to the Collateral Agent, its successors and assigns, for the benefit of the applicable 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 Pledged Collateral and Article 9 Collateral of the New Subsidiary. Each reference to a “Grantor” in the Collateral Agreement shall be deemed to include the New Subsidiary. The Collateral Agreement is hereby incorporated herein by reference.

SECTION 2. The New Subsidiary represents and warrants to the Collateral Agent, on behalf of the 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.

SECTION 3. This Supplement may be executed in counterparts, each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Supplement shall become effective when the Collateral Agent shall have received a counterpart of this Supplement that bears the signature of the New Subsidiary and the Collateral Agent has executed a counterpart hereof. Delivery of an executed signature page to this Supplement by facsimile or electronic transmission shall be as effective as delivery of a manually signed counterpart of this Supplement.

SECTION 4.

SECTION 5. Except as expressly supplemented hereby, the Collateral Agreement shall remain in full force and effect.

SECTION 6. THIS SUPPLEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

SECTION 7. In case any one or more of the provisions contained in this Supplement should be held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein and in the Collateral Agreement shall not in any way be affected or impaired thereby (it being understood that the invalidity of a particular provision in a particular jurisdiction shall not in and of itself affect the validity of such provision in any other jurisdiction). 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 Collateral Agreement.

SECTION 9. The New Subsidiary agrees to reimburse the Collateral Agent for its reasonable out-of-pocket expenses in connection with this Supplement, including the reasonable fees, other charges and disbursements of counsel for the Collateral Agent.

IN WITNESS WHEREOF, the New Subsidiary and the Collateral Agent have duly executed this Supplement to the Collateral Agreement as of the day and year first above written.
