Subject to Section 2.1, upon, or at any time after, a Development Compound is selected by Exelixis as a Development Candidate pursuant to Section 3.3.2 of the Development Agreement, GSK agrees to make available to Exelixis one or more Product Specific Advances with respect to such Development Candidate[*]. 2.2 Borrowing Notices. Subject to this Article 2, Exelixis may notify GSK to make available an Advance (each such notice, a "Borrowing Notice") by delivering to GSK a written request substantially in the form of Exhibit D attached hereto. The Borrowing Notice shall state the amount, the Borrowing Date of such Advance (which Borrowing Date must be a Business Day not earlier than fifteen (15) Business Days after the Borrowing Notice is effective pursuant to Section 16.5) and all other documents and instruments required pursuant to the terms and conditions of the Loan Documents. GSK is entitled to rely upon the Borrowing Notice and the covenants of Exelixis' officers who sign such Borrowing Notices.

Subject to the terms and conditions of the Loan Documents, GSK shall make available to Exelixis the Advance requested by Exelixis on the Borrowing Date specified in each applicable Borrowing Notice by wire transfer to the Deposit Account. ARTICLE 3 SECURITY INTEREST 3.1 Grant of Security Interest. To secure the payment and performance by Exelixis of the Obligations to GSK, Exelixis and, to the extent applicable, its Affiliates hereby pledge, set over, assign, deliver and grant a first and only priority security interest to GSK in all of Exelixis' and, to the extent applicable, its Affiliates' right, title and interest in the following assets, wherever located and whether now existing or hereafter created and whether now owned or hereafter acquired, of every description, tangible and intangible (the "Collateral"): 3.1.1 [*]; 3.1.2 [*]; 3.1.3 Deposit Account. That certain deposit account with a mutually agreed upon bank or financial institution, initially [*], more particularly described on Schedule 3.1.3 (the "Deposit Account") maintained by Exelixis into which the proceeds of the Advances, including without limitation investment property, shall be deposited and, subject to Section 9.5, maintained, with all dividends and distributions, whether payable in cash, securities or other investment property accruing on the balance therein, all of which are described and governed by the Control Agreement; 3.1.4 [*]; 3.1.5 Capital Equipment. All capital equipment (currently defined as equipment with a purchase price per item in excess of Five Thousand Dollars ($5,000)), purchased by Exelixis with the proceeds of the Advances, having a specific use solely to perform the activities contemplated under the Development Agreement, in all cases however and wherever arising (the "Capital Equipment"); and 3.1.6 Proceeds. All Proceeds and products of the Intellectual Property, the Deposit Account, the Development Candidate Inventory and/or the Capital Equipment. ARTICLE 4 INTEREST 4.1 Interest 4.1.1 Advances Each Advance shall bear interest on the sum of the unpaid principal balance thereof outstanding on each day until repaid, at a rate per annum equal to four percent (4.0%). 4.1.2 Default Rate of Interest. Notwithstanding the rate of interest specified in Section 4.1.1, effective immediately upon the occurrence of an Event of Default under Article 12, and for so long thereafter as any such Event of Default shall be continuing and to the extent permitted by law, the aggregate principal balance of all Advances then outstanding and, to the extent permitted by applicable law, any accrued interest thereon, shall bear interest at the Default Rate of Interest. Exelixis hereby acknowledges that (a) such Default Rate of Interest is a material inducement to GSK to make Advances available to Exelixis; (b) GSK would not have made the Advances available to Exelixis in the absence of the agreement of Exelixis to pay such Default Rate of Interest; (c) such Default Rate of Interest represents compensation for increased risk to GSK that the Advances will not be repaid and (d) such Default Rate of Interest is not a penalty and represents a reasonable estimate of (i) the cost to GSK in allocating its resources (both personnel and financial) to the administration and collection of the Advances and (ii) compensation to GSK for losses that are difficult to ascertain. 4.1.3 Change of Control Rate of Interest. In the event of termination of the Development Agreement as provided in Sections 13.1.2(d)(i) or 13.1.2(d)(ii) of the Development Agreement, the aggregate principal balance of all Advances then outstanding and, to the extent permitted by applicable law, any accrued interest thereon, shall bear interest at the Change of Control Rate of Interest from and after the date of such termination. 4.1.4 Interest Computations. All interest chargeable under the Loan Documents shall be computed on the basis of a three hundred sixty (360) day year for the actual number of days elapsed. ARTICLE 5 REPAYMENT 5.1 Repayment. Payment hereunder may be made by Exelixis in cash pursuant to Section 5.3, Common Stock pursuant to Section 5.6, or by a combination of the foregoing. Unless earlier paid through offsets pursuant to Section 5.4 or pursuant to Section 5.5 below, all Advances made hereunder, together with all accrued and unpaid interest, shall be due and payable to GSK on the earlier of [*], or (b) demand made in accordance with Section 13.1. 5.2 Payments on Non-Business Day. In the event that any payment of principal, interest, fees or any other amounts payable by Exelixis pursuant to the Loan Documents shall become due on any day which is not a Business Day, such due date shall be extended to the next succeeding Business Day, and, to the extent applicable, interest shall continue to accrue and be payable at the applicable rate for and during any such extension. 5.3 Cash Payment Procedures. All sums payable by Exelixis to GSK in cash under the Loan Documents, whether principal, interest, or otherwise, shall be paid in lawful money of the United States and payable in immediately available funds, when due, by wire transfer to an account of GSK as GSK may reasonably direct, without setoff, deduction or counterclaim (except as provided in Section 5.4 below). 5.4 Milestone Payments. Upon the satisfaction of the conditions set forth therein, GSK is obligated to make certain milestone payments to Exelixis pursuant to the terms of the Development Agreement. All Product Acceptance Milestone payments under Section 6.2.1 of the Development Agreement and commercialization milestone payments under Section 6.2.3 of the Development Agreement to be made to Exelixis may, at GSK's option, be immediately credited against the Advances and accrued interest then outstanding under the Note, by direct offset. All such credits shall be applied first to expenses or charges, then to accrued interest, and then to principal on the date such milestone payments are first due and payable. Any such credits to the Total Advanced Amount shall not entitle Exelixis to obtain any additional Advances. During the Repayment Period, milestone payments shall be applied to payments due in the direct order of maturity. GSK shall promptly provide Exelixis in writing a reconciliation of the amount of each such credit and its application to the amounts payable under the Note. 5.5 Optional Cash Prepayments. Exelixis may prepay, in cash, the unpaid principal amount of any Advance in whole or in part without penalty or premium at any time and from time to time, in cash only, and as provided for in Section 5.3. Partial prepayments shall be applied first to expenses and charges, then to interest and then to principal, and during the Repayment Period, to payments due in direct order of maturity. 5.6 Repayment By Common Stock. 5.6.1 Exercise of Issuance Rights. Subject to Section 5.6.6, prior to a Payment Date, upon notice to GSK pursuant to Section 5.6.3 (a "Stock Repayment Notice"), Exelixis shall have the option to issue to GSK the Stock Repayment Shares in payment of all or any portion of the then outstanding principal amount of any Advance, and all accrued interest relating thereto up to and including the Payment Date (the "Stock Repayment Amount") (each such instance being hereinafter referred to as "Stock Repayment"). The number of shares of Common Stock comprising the Stock Repayment Shares issuable in connection with Stock Repayments shall be equal to the quotient of the applicable Stock Repayment Amount divided by the Fair Market Value (as defined below) of one share of Common Stock. No fractional shares shall be issued in connection with a Stock Repayment. The "Fair Market Value" of the Common Stock shall be deemed to be the average of the opening and closing sale prices of the Common Stock as reported by the National Securities Market on which the Common Stock trades or is listed for the first twenty (20) consecutive Trading Days immediately following the date which is two (2) Trading Days after Exelixis filed its most recent periodic disclosure on Form 10-Q or Form 10-K prior to the date of each Stock Repayment Notice. 5.6.2 Limitation on Ownership.

In the event that any purchase of Option Shares (as defined in the Stock Purchase Agreement) or Stock Repayment Shares would cause GSK to be a holder of twenty percent (20%) or more of Exelixis' then outstanding Common Stock, GSK shall be relieved of its obligations to make such purchase(s) or from accepting such repayment in lieu of cash, to the extent of the overage. 5.6.3 Stock Repayment Notice.

Each such Stock Repayment Notice shall state the Stock Repayment Amount applicable to the Stock Repayment. 5.6.4 Delivery of Stock Repayment Shares. At least three (3) Trading Days in advance of any Stock Repayment Closing Date, Exelixis shall issue instructions as follows: (a) If GSK is not an SEC Affiliate of Exelixis, then Exelixis shall issue instructions to Exelixis' stock transfer agent directing Exelixis' transfer agent to prepare and deliver to the account of GSK by an automated share transfer through the Depository Trust Company system ("DWAC"), that number of shares of Common Stock representing the applicable Stock Repayment Shares no later than the Stock Repayment Closing Date; (b) If GSK is an SEC Affiliate of Exelixis as of the applicable Stock Repayment Closing Date, then Exelixis shall issue instructions to Exelixis' stock transfer agent, directing the transfer agent to prepare and deliver to Exelixis a stock certificate representing that number of shares of Common Stock representing the applicable Stock Repayment Shares, as soon as possible, but in no event later than one (1) Trading Day prior to the applicable Stock Repayment Closing Date, which stock certificate shall be delivered by Exelixis to GSK on the applicable Stock Repayment Closing Date; provided however, that Exelixis may only issue Stock Repayment Shares in accordance with this Section 5.6; or c) Subject to GSK's receipt of the stock certificate or DWAC transfer, as the case may be, for the Stock Repayment Shares, the outstanding Obligations prior to such Stock Repayment shall be deemed repaid to the extent of the applicable Stock Repayment Amount. 5.6.5 No Rights as Stockholders.

ARTICLE 13 GSK'S RIGHTS AND REMEDIES UPON DEFAULT 13.1 Rights and Remedies. Upon the occurrence of, and during the continuance of, an Event of Default, GSK may, at its election, without notice of its election and without demand, do any one or more of the following, all of which are authorized by Exelixis: 13.1.1 declare all Obligations, evidenced by the Loan Documents, immediately due and payable (provided, that upon the occurrence of an Event of Default described in Section 12.1.5, all Obligations shall become immediately due and payable without any action by GSK); 13.1.2 cease advancing money or extending credit to or for the benefit of Exelixis under this Loan Agreement; 13.1.3 cease accepting Stock Repayments pursuant to Section 5.6; 13.1.4 institute legal or deficiency proceedings or otherwise enforce its rights to collect the Total Advance Amount with all accrued interest thereon against Exelixis which becomes immediately due and payable. If a judgment is entered in favor of GSK, the lien of the judgment relates back to the earliest date of perfection of GSK's security interests hereunder; 13.1.5 charge, setoff and withdraw from any credit balance which Exelixis may then have with GSK or with any Affiliate thereof, such amounts as may be necessary to satisfy the Total Advance Amount with all accrued interest thereon; 13.1.6 terminate and cancel any existing commitment to Exelixis for future Advances; 13.1.7 with or without judicial process, to the extent permitted by law, and subject to the final sentence of this Section 13.1.7, (i) to seize the Collateral or to require Exelixis to assemble the Collateral or (ii) to render the Collateral unusable without need for GSK to post a bond or security or (iii) demand Exelixis to make the Collateral available at a GSK designated place for sale, license or other disposition by GSK (and if such disposition is to GSK, at a public auction unless the Collateral is that customarily sold on a recognized market or the subject of widely distributed standard price quotations) (iv) exercise its rights to seize the Collateral and any remedies set forth under the Control Agreement and/or the Patent Office Filing to satisfy the Obligations with all accrued interest thereon without any right of Exelixis to adjourn such disposition. Any such sale, license or other disposition may be made of the Collateral in its present condition or following any commercially reasonable preparation or processing at the expense of Exelixis. Notwithstanding anything contained herein, GSK shall have no immediate right to proceed against any of the Excluded Collateral if GSK alleges an Event of Default pursuant to Sections 12.1.2, 12.1.4(b) or 12.1.4(c), prior to the completion of the dispute resolution process in accordance with Section 16.2, undertaken to determine the existence of such alleged Event of Default pursuant to such sections, and if such dispute resolution process conclusively determines the existence of an Event of Default by Exelixis under such sections, then, GSK shall be entitled to proceed against the Excluded Collateral; or 13.1.8 to effectuate collection of any Collateral comprising accounts, GSK may reassign any such account, to Exelixis (without recourse to GSK) and require Exelixis to proceed with such legal or other action, at Exelixis' sole liability, cost and expense, in which event all amounts collected by Exelixis on such items are to, nevertheless, be treated as Proceeds of Collateral. In furtherance of GSK's rights and remedies hereunder, Exelixis hereby grants a power of attorney to GSK to endorse Exelixis' name on checks, notes, acceptances, drafts and any other documents or instruments requiring Exelixis' endorsement, to change the address where Exelixis' mail should be sent and to open all mail and to do such other acts and things necessary to effectuate the purposes of the Loan Documents when so permitted by the terms of the Loan Documents. 13.2 Application of Proceeds of Disposition of Collateral. The proceeds of any sale, license or other disposition of the Collateral are to be applied to satisfy the following items in the following order: 13.2.1 First, to GSK's expenses in preserving its interests and rights hereunder, to expenses incurred by GSK in realizing upon security interests created or referred to herein, and expenses of GSK in enforcing and defending its rights as set forth in Article 14; 13.2.2 Second, to the Total Advance Amount with all accrued interest thereon and any expenses not satisfied under Section 13.2.1; 13.2.3 Third, any excess or amounts remaining are to be paid to any subordinate security interest or lien if the holder thereof supplies proof of its interest or lien and if the holder thereof makes an authenticated demand therefor before distribution and any balance thereafter shall be paid to Exelixis unless GSK reasonably determines that reserves are warranted to implement the indemnification provisions in Article 15; and 13.2.4 Fourth, a transferee who purchases, licenses or otherwise receives the benefits of a disposition of Collateral after an Event of Default takes free of all Exelixis' rights and the rights of any subordinate security interest or lien. A transferee is entitled to the recording of a transfer statement to document public notice of such disposition. 13.3 Notice of Disposition of Collateral. GSK shall give authenticated reasonable notice to Exelixis and any other party entitled thereto under applicable law of the time and place of a public sale, license or other disposition of the Collateral. Authenticated notice is presumed to be reasonable (a) if given ten (10) days prior to such disposition, (b) if sent to the chief executive officer and, if none, to the address of Exelixis set forth in Section 16.5 and (c) if it contains a statement of the Collateral and its intended disposition, the time and place of disposition and a statement that Exelixis is entitled to an accounting of such disposition. GSK may disclaim any warranties that may apply to any sale, lease, license or other disposition of the Collateral. 13.4 Marshalling of Assets. GSK has no obligation whatsoever to proceed first against any of the Collateral before proceeding against any other of the Collateral. It is expressly understood and agreed that all of the Collateral stands as equal security for Obligations and any interest accrued thereon and that GSK has the right to proceed against or dispose of any/or all of the Collateral or other collateral in any order as GSK, in its sole discretion, determines. 13.5 Waiver of Defaults. No Event of Default shall be waived by GSK except in a written instrument specifying the scope and terms of such waiver and signed by an authorized officer of GSK, and such waiver shall be effective only for the specific times and purposes given. No single or partial exercise of any right, power or privilege hereunder, nor any delay in the exercise thereof, shall preclude other or further exercise of GSK's rights. No waiver of any Event of Default shall extend to any other or further Event of Default. No forbearance on the part of GSK in enforcing any of GSK's rights or remedies hereunder or any of the Transaction Documents shall constitute a waiver of any of its rights or remedies. 13.6 Remedies Cumulative. GSK's rights and remedies under the Loan Documents and all other Transaction Documents shall be cumulative. GSK shall have all other rights and remedies not expressly set forth herein as provided under applicable law, or in equity. No exercise by GSK of one right or remedy shall be deemed an election, and no waiver by GSK of any Event of Default on Exelixis' part shall be deemed a continuing waiver. No delay by GSK shall constitute a waiver, election, or acquiescence by it. No waiver by GSK shall be effective unless made in a written document signed on behalf of GSK and then shall be effective only in the specific instance and for the specific purpose for which it was given. 13.7 Waiver. Exelixis waives demand, protest, notice of protest, notice of default or dishonor, notice of payment and nonpayment, notice of any default, nonpayment at maturity, release, compromise, settlement, extension, or renewal of accounts, documents, instruments, chattel paper, and guarantees at any time held by GSK on which Exelixis may in any way be liable. ARTICLE 14 GSK'S RIGHTS AND REMEDIES EXCLUSIVE OF DEFAULT Exclusive of an Event of Default, GSK possesses the following rights and remedies: 14.1 UCC. At all times prior to and following an Event of Default, GSK is entitled to all the rights and remedies of a secured party under the UCC as now or hereafter enacted; 14.2 Preservation of Collateral. At any time prior to and following an Event of Default, GSK, without notice, in its sole reasonable discretion, may take any and all action which, in its sole reasonable discretion, is necessary and proper to preserve the Collateral, or GSK's interests under this Loan Agreement, including without limitation, those duties of Exelixis imposed by this Loan Agreement. Any sums so expended by GSK are to be secured by the Collateral and treated as though additional Advances for purposes of calculating the Total Advance Amount. Such sums (including reasonable attorneys' fees) are to be payable on demand with interest at the Default Rate of Interest repaid by Exelixis. GSK may also demand that escrow accounts be established to fund anticipated future expenditures; or 14.3 Power of Attorney. GSK is hereby irrevocably appointed and authenticated by Exelixis as its lawful attorney and agent in fact to file, authenticate or execute financing statements and other documents and agreements as GSK may deem necessary for the purpose of perfecting any security interests, or liens under any applicable law. All acts by GSK or its designee are hereby ratified and approved, and neither GSK, nor its designee, shall be liable for any acts of omission or commission, or for any error of judgment or mistake unless the result of gross negligence of willful misconduct. The powers of attorney granted to GSK in this Loan Agreement are coupled with an interest and are irrevocable during the Term. ARTICLE 15 INDEMNIFICATION 15.1 Indemnification of GSK. Exelixis agrees to and hereby indemnify and hold GSK harmless from and against, and to reimburse GSK with respect to, any and all claims, demands, causes of action, losses, damages, liabilities, costs and expenses (including consequential damages, attorneys' fees and court costs) of any and every kind or character, known or unknown, fixed or contingent, asserted against or incurred by GSK at any time and from time to time by reason of or arising out of: 15.1.1 the breach of any representation, warranty or covenant of Exelixis set forth in the Loan Documents; 15.1.2 the failure of Exelixis to perform any obligation herein required to be performed by Exelixis; or 15.1.3 the ownership, construction, operation, use and maintenance of the Collateral other than by GSK. 15.1.4 Duration of Indemnity. This covenant survives for the Term notwithstanding whether Exelixis has been released and discharged or whether GSK becomes the owner of the Collateral. ARTICLE 16 MISCELLANEOUS 16.1 Publicity.

If the dispute is not resolved within such [*], either Party may commence litigation with respect to the subject matter of the dispute and with respect to any other claims it may have and thereafter neither Party hereto shall have any further obligation under this Section 16.2. 16.3 Choice of Law. This Loan Agreement and any dispute arising from the performance or breach hereof shall be governed by and construed and enforced in accordance with the laws of State of New York, U.S.A., unless such dispute is governed under the laws of the UCC in which case the UCC shall apply, without reference to conflicts of laws principles. 16.4 Subordination. The Obligations are expressly made subordinate in right of payment to all other obligations and indebtedness of Exelixis existing as of the Effective Date and listed on Schedule 16.4 and all refinancings (in an amount equal to or less than the original indebtedness), extensions, and renewals thereof.

Exelixis shall remain liable for any deficiency with respect to the Obligations of Exelixis to GSK, which shall bear interest and be payable at the Default Rate of Interest under the Loan Agreement. The rights of Exelixis to receive any surplus shall be subject to any duty of GSK imposed by law to the holder of any subordinate security interest in the Collateral known to GSK. Nothing contained herein shall be construed as requiring GSK to take any such action at any time. ARTICLE 8 MISCELLANEOUS 8.1 Amendments and Modification.

If any provision hereof should be held invalid, illegal or unenforceable in any jurisdiction, the Parties shall negotiate in good faith a valid, legal and enforceable substitute provision that most nearly reflects the original intent of the Parties and all other provisions hereof shall remain in full force and effect in such jurisdiction and shall be liberally construed in order to carry out the intentions of the Parties hereto as nearly as may be possible.

Limitation on SVBS' and Clearing Broker's Rights in the Collateral. SVBS ------------------------------------------------------------------ and Clearing Broker will not attempt to assert control and does not claim and will not accept any security or other interest in any part of the Collateral, and SVBS and Clearing Broker will not exercise, enforce or attempt to enforce on their own behalves any right of setoff against the Collateral, or otherwise charge or deduct from the Collateral on SVBS' or Clearing Broker's behalves any amount whatsoever, other than for: security interests, liens, encumbrances, ----------- claims or rights of setoff for the payment of any amounts owed by Customer to SVBS and/or Clearing Broker arising in connection with SVBS' and Clearing Broker's customary fees and commissions pursuant to their agreement with Customer or for the payment for financial assets and securities purchased for the Account (the "Account Claims"). Customer and Creditor hereby acknowledge that any security interests, liens, encumbrances, claims or rights of setoff for the payment of any amounts owed by Customer to SVBS and Clearing Broker arising in connection with the Account Claims shall at all times be prior to the rights of Creditor in the Collateral and Securities whether or not Creditor sends to SVBS a Notice of Exclusive Control described below. 7. Agreement for Control. ----------------------- (a) SVBS and Clearing Broker will comply with all entitlement orders (including requests to withdraw Collateral from the Account) originated by Customer with respect to the Collateral, or any portion of the Collateral, without further consent by Creditor until such time as SVBS receives from Creditor (in accordance with Section 17 below) a written notice to SVBS that Creditor is thereby exercising exclusive control over the Account (a "Notice of Exclusive Control."). The Notice of Exclusive Control must be in the form set forth in EXHIBIT B hereto. SVBS or Clearing Broker have no obligation whatsoever to confirm that Creditor is entitled to send a Notice of Exclusive Control in connection with the Account or that the Creditor's representative who signs any Notice of Exclusive Control is authorized to do so. SVBS and Clearing Broker (upon instruction from SVBS) will, upon SVBS' receipt of such Notice of Exclusive Control, proceed in accordance with the remainder of this Section 7 even if Creditor's instructions are contrary to any instructions or demands that Customer may give to SVBS or Clearing Broker. After SVBS receives a Notice of Exclusive Control and has had reasonable opportunity to comply with it, but no later than two (2) Business Days ("Business Days" means days which SVBS is open to the public for business and are measured in 24 hour increments) after receipt of the Notice of Exclusive Control (in accordance with Section 17 below), SVBS and Customer agree that SVBS and Clearing Broker will: (i) cease complying with entitlement orders or other directions concerning the Account and Collateral that are originated by Customer or its representatives until such time as SVBS receives a written notice from Creditor rescinding the Notice of Exclusive Control; and (ii) comply with the entitlement orders and instructions provided to SVBS by Creditor without investigating: the reason for any action taken by Creditor; the amount of any obligations of Customer to Creditor; the validity of any of Creditor's agreements with Customer; or the existence of any defaults under such agreements. (b) Notwithstanding the foregoing, Creditor agrees that upon receipt of Creditor's Notice of Exclusive Control, SVBS and Clearing Broker may take all steps necessary to satisfy or settle any Account Claims, may respond as required pursuant to the terms of any other account control agreement with respect to which SVBS believes it previously received a Notice of Exclusive Control or similar notice, and may respond as required by law to any court or government order, writ or other legal process received by SVBS or Clearing Broker. Creditor also agrees that, before SVBS' receipt of Creditor's Notice of Exclusive Control, SVBS and Clearing Broker may be required to and may respond to (i) Notices of Exclusive Control or similar notices sent to SVBS by other parties and (ii) a writ or other similar legal process served on SVBS or Clearing Broker in connection with the Account and Collateral. SVBS and Clearing Broker agree to use good faith efforts to promptly notify Creditor if any other party delivers to SVBS a notice of exclusive control or any party other than Creditor or SVBS asserts a claim against the Collateral by means of a writ or other similar legal process, but failure to provide such notice does not constitute a breach of this Agreement. Customer expressly agrees that SVBS, Clearing Broker and Creditor may act in accordance with the terms of this Section 7. 8. Customer Waiver and Authorization. Customer hereby waives any rights ------------------------------------ that Customer may have under the Client Agreement to the extent such rights are inconsistent with the provisions of this Agreement, and hereby authorizes SVBS and Clearing Broker to comply with all instructions and entitlement orders delivered by Creditor to SVBS in accordance with the terms of this Agreement. 9.

Termination of this Agreement. Creditor may terminate this Agreement by -------------------------------- giving SVBS and Customer written notice of termination; provided that, by giving such notice, Creditor acknowledges that it will thereby be confirming that, as of the termination date, it will no longer have a perfected security interest in the Account and Securities in the Collateral which is perfected by control via this Agreement, although Creditor may continue to have a perfected security interest in the Account by other means. SVBS and Clearing Broker may terminate this Agreement by giving Creditor and Customer 30 days prior written notice of termination (unless a shorter notice period is mandated by applicable law). Customer may only terminate this Agreement with the written consent of Creditor; provided that, by giving such notice with Creditor's written consent, both Customer and Creditor acknowledge that they will thereby be confirming that, as of the termination date, Creditor will no longer have a perfected security interest in the Collateral which is perfected by control pursuant to this Agreement, although Creditor may continue to have a perfected security interest in the Collateral by other means. 11 Delivery of Account Statements. SVBS and Clearing Broker are hereby --------------------------------- authorized by Customer and agree to send to Creditor at its address for notices set forth below Creditor's signature block at the end of this Agreement, concurrently with the sending thereof to Customer, duplicate copies of any and all monthly statements or reports issued or sent to Customer with respect to the Collateral and the Account.
