(h) The Company shall, (i) on or prior to the date of the first Borrowing, in the case of Equipment now owned and (ii) within 10 days of acquiring any other Equipment, deliver to the Collateral Agent any and all certificates of title, applications for title or similar evidence of ownership of such Equipment and shall cause the Collateral Agent to be named as lienholder on any such certificate of title or other evidence of ownership.

(m) The Issuer agrees to notify the Collateral Agent immediately upon filing any application for, or otherwise acquiring ownership of or a registration relating to, any copyright, Patent or Trademark. At any time and from time to time thereafter, the Collateral Agent may (and shall upon instruction from the Required Lenders) require either Company to, at its expense and upon the request of the Collateral Collateral Agent, file (as appropriate) the Patent Security Agreement and the Trademark Security Agreement with the United States Patent and Trademark Office and a copyright security agreement (in form and substance satisfactory to the Collateral Agent) with the United States Copyright Office, and take such other actions as may be necessary or reasonably desirable, or that the Collateral Agent may reasonably request, in order to create and perfect the security interests in such Patents, Trademarks or copyrights, as the case may be. The Issuer shall notify the Collateral Agent immediately if it knows that any application or registration relating to any Patent or Trademark may become abandoned or dedicated to the public (other than applications or registrations (x) with respect to any such Patents or Trademarks that are no longer used or useful in the business of the Issuer or whose minimal value does not reasonably justify the cost of maintaining such registration or application, or (y) that have been refused by the applicable patent or trademark registry) or of any 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, or any court) regarding the Issuer's ownership of any Patent or Trademark, its right to register the same, or to keep and maintain the same. In the event that any right to any Patent, Patent License, Trademark or Trademark License of either Company is infringed, misappropriated or diluted by a third party, the Issuer shall notify the Collateral Agent promptly after it learns thereof and shall, unless the Issuer shall reasonably determine that any such action would be of negligible economic value, promptly sue for infringement, misappropriation or dilution and to recover any and all damages for such infringement, misappropriation or dilution, and take such other actions as the Issuer shall reasonably deem appropriate under the circumstances to protect such Patent, Patent License, Trademark or Trademark License. In no event shall either Company, either by itself or through any agent, employee or licensee, file an application for the registration of any Patent or Trademark with the United States Patent and Trademark Office, or with any similar office or agency of the United States, any State thereof, the District of Columbia or with any similar office or agency in any other country or any political subdivision thereof, unless not less than 10 days prior thereto it informs the Collateral Agent, and, upon request of the Collateral Agent, executes and delivers any and all agreements, instruments, 13 documents and papers the Collateral Agent may request to evidence the Security Interests in such Patent or Trademark and the goodwill and general intangibles of the Issuer relating thereto or represented thereby, and the Issuer hereby constitutes the Collateral Agent its attorney-in-fact to execute and file all such writings for the foregoing purposes, all acts of such attorney being hereby ratified and confirmed; such power being coupled with an interest, shall be irrevocable until the Secured Obligations are paid in full. (n) From time to time upon request by the Collateral Agent, the Company shall, at its cost and expense, cause to be delivered to the Purchasers an opinion of counsel satisfactory to the Collateral Agent as to such matters relating to the transactions contemplated hereby as the Required Purchasers may reasonably request.

(b) The Company shall instruct all account debtors and other Persons obligated in respect of all Accounts to make all payments in respect of the Accounts either (i) directly to the Collateral Agent (by instructing that such payments be remitted to a post office box which shall be in the name and under the control of the Collateral Agent) or (ii) to one or more other banks in any state (other than Louisiana) in the United States (by instructing that such payments be remitted to a post office box which shall be in the name and under the control of such bank) under a Lockbox Letter substantially in the form of Exhibit C hereto duly executed by the Company and such bank or under other arrangements, in form and substance satisfactory to the Collateral Agent, pursuant to which the Company shall have irrevocably instructed such other bank (and such other bank shall have agreed) to remit all proceeds of such payments directly to the Collateral Agent for deposit into the Collateral Account or as the Collateral Agent may 14 otherwise instruct such bank.

In addition to the foregoing, the Company agrees that if the proceeds of any Collateral hereunder (including the payments made in respect of Accounts) shall be received by it, the Company shall as promptly as possible deposit such proceeds into the Collateral Account. Until so deposited, all such proceeds shall be held in trust by the Company for and as the property of the Secured Parties and shall not be commingled with any other funds or property of the Company. (c) The balance from time to time standing to the credit of the Collateral Account shall, except upon the occurrence and continuation of an Event of Default, be distributed to the Company upon the order of the Company. If immediately available cash on deposit in the Collateral Account is not sufficient to make any distribution to the Company referred to in the previous sentence of this Section 5(c), the Collateral Agent shall liquidate as promptly as practicable Liquid Investments as required to obtain sufficient cash to make such distribution and, notwithstanding any other provision of this Section 5, such distribution shall not be made until such liquidation has taken place.

(d) Amounts on deposit in the Collateral Account shall be invested and re-invested from time to time in such Liquid Investments as the Company shall determine, which Liquid Investments shall be held in the name and be under the control of the Collateral Agent, provided that, if an Event of Default has occurred and is continuing, the Collateral Agent shall, if instructed by the Required Lenders, liquidate any such Liquid Securities and apply or cause to be applied the proceeds thereof to the payment of the Secured Obligations in the manner specified in Section 9. For this purpose, "Liquid Investments" means the investments listed in clauses (b) and (c) of the definition of "Permitted Investments" in the Credit Agreement; provided that (x) each Liquid Investment shall mature within 30 days after it is acquired by the Collateral Agent and (y) in order to provide the Collateral Agent, for the benefit of the Secured Parties, with a perfected security interest therein, each Liquid Investment shall be either: (i) evidenced by negotiable certificates or instruments, or if non-negotiable then issued in the name of the Collateral Agent, which (together with any appropriate instruments of transfer) are delivered to, and held by, the Collateral Agent or an agent thereof (which shall not be the Company or any of its Affiliates) in the State of New York; or 15 (ii) in book-entry form and issued by the United States and subject to pledge under applicable state law and Treasury regulations and as to which (in the opinion of counsel to the Collateral Agent) appropriate measures shall have been taken for perfection of the Security Interests. SECTION 6. General Authority. The Company hereby irrevocably appoints the Collateral Agent its true and lawful attorney, with full power of substitution, in the name of the Company, the Collateral Agent, the Secured Parties or otherwise, for the sole use and benefit of the Secured Parties, but at the Company's expense, to the extent permitted by law to exercise, at any time and from time to time while an Event of Default has occurred and is continuing, all or any of the following powers with respect to all or any of the Collateral: (a) to demand, sue for, collect, receive and give acquittance for any and all monies due or to become due thereon or by virtue thereof, (b) to settle, compromise, compound, prosecute or defend any action or proceeding with respect thereto, (c) to sell, transfer, assign or otherwise deal in or with the same or the proceeds or avails thereof, as fully and effectually as if the Collateral Agent were the absolute owner thereof, and (d) to extend the time of payment of any or all thereof and to make any allowance and other adjustments with reference thereto; provided that the Collateral Agent shall give the Company not less than ten days' prior notice of the time and place of any sale or other intended disposition of any of the Collateral, except any Collateral which is perishable or threatens to decline speedily in value or is of a type customarily sold on a recognized market. The Collateral Agent and the Company agree that such notice constitutes "reasonable notification" within the meaning of Section 9-504(3) of the UCC. SECTION 7. Remedies upon Event of Default. (a) If any Event of Default has occurred and is continuing, the Collateral Agent may exercise on behalf of the Secured Parties all rights of a secured party under the UCC (whether or not in effect in the jurisdiction where such rights are exercised) and, in addition, the Collateral Agent may, without being required to give any notice, except as herein provided or as may be required by mandatory provisions of law, (i) withdraw all cash and Liquid Investments in the Collateral Account and apply such cash and Liquid Investments and other cash, if any, then held by it as Collateral as specified in Section 9 and (ii) if there shall be no such cash or Liquid Investments or if such cash and Liquid Investments shall be insufficient to pay all the Secured 16 Obligations in full, sell the Collateral or any part thereof at public or private sale, for cash, upon credit or for future delivery, and at such price or prices as the Collateral Agent may deem satisfactory. Any Secured Party may be the purchaser of any or all of the Collateral so sold at any public sale (or, if the Collateral is of a type customarily sold in a recognized market or is of a type which is the subject of widely distributed standard price quotations, at any private sale). The Company will execute and deliver such documents and take such other action as the Collateral Agent deems necessary or advisable in order that any such sale may be made in compliance with law. Upon any such sale the Collateral Agent shall have the right to deliver, assign and transfer to the purchaser thereof the Collateral so sold. Each purchaser at any such sale shall hold the Collateral so sold to it absolutely and free from any claim or right of whatsoever kind, including any equity or right of redemption of the Company which may be waived, and the Company, to the extent permitted by law, hereby specifically waives all rights of redemption, stay or appraisal which it has or may have under any law now existing or hereafter adopted. The notice (if any) of such sale required by Section 6 shall (A) in the case of a public sale, state the time and place fixed for such sale, and (B) in the case of a private sale, state the day after which such sale may be consummated. 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 in the notice of such sale. At any such sale the Collateral may be sold in one lot as an entirety or in separate parcels, as the Collateral Agent may determine. The Collateral Agent shall not be obligated to make any such sale pursuant to any such notice. 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 the sale, and such sale may be made at any time or place to which the same may be so adjourned. In the case of any sale of all or any part of the Collateral on credit or for future delivery, the Collateral so sold may be retained by the Collateral Agent until the selling price is paid by the purchaser thereof, but the Collateral Agent shall not incur any liability in the case of the failure of such purchaser to take up and pay for the Collateral so sold and, in the case of any such failure, such Collateral may again be sold upon like notice. The Collateral Agent, instead of exercising the power of sale herein conferred upon it, may proceed by a suit or suits at law or in equity to foreclose the Security Interests and sell the Collateral, or any portion thereof, under a judgment or decree of a court or courts of competent jurisdiction. (b) For the purpose of enforcing any and all rights and remedies under this Agreement the Collateral Agent may (i) require the Company to, and the Company agrees that it will, at its expense and upon the request of the Collateral Agent, forthwith assemble all or any part of the Collateral as directed by the Collateral Agent and make it available at a place designated by the Collateral 17 Agent which is, in its opinion, reasonably convenient to the Collateral Agent and the Company, whether at the premises of the Company or otherwise, (ii) to the extent permitted by applicable law, enter, with or without process of law and without breach of the peace, any premise where any of the Collateral is or may be located, and without charge or liability to it seize and remove such Collateral from such premises, (iii) have access to and use the Company's books and records relating to the Collateral and (iv) prior to the disposition of the Collateral, store or transfer it without charge in or by means of any storage or transportation facility owned or leased by the Company, process, repair or recondition it or otherwise prepare it for disposition in any manner and to the extent the Collateral Agent deems appropriate and, in connection with such preparation and disposition, use without charge any trademark, trade name, copyright, patent or technical process used by the Company. The Collateral Agent may also render any or all of the Collateral unusable at the Company's premises and may dispose of such Collateral on such premises without liability for rent or costs. SECTION 8. Limitation on Duty of Collateral Agent in Respect of Collateral. Beyond the exercise of reasonable care in the custody thereof, the Collateral Agent shall have no duty as to any Collateral in its possession or control or in the possession or control of any agent or bailee or any income thereon or as to the preservation of rights against prior parties or any other rights pertaining thereto. The Collateral Agent shall be deemed to have exercised reasonable care in the custody of the Collateral in its possession if the Collateral is accorded treatment substantially equal to that which it accords its own property, and shall not be liable or responsible for any loss or damage to any of the Collateral, or for any diminution in the value thereof, by reason of the act or omission of any warehouseman, carrier, forwarding agency, consignee or other agent or bailee selected by the Collateral Agent in good faith. SECTION 9. Application of Proceeds. Upon the occurrence and during the continuance of an Event of Default, the proceeds of any sale of, or other realization upon, all or any part of the Collateral and any cash held in the Collateral Account shall be applied by the Collateral Agent in the following order of priorities: first, to pay the expenses of such sale or other realization, including reasonable compensation to agents and counsel for the Collateral Agent, and all expenses, liabilities and advances incurred or made by the Collateral Agent in connection therewith, and any other unreimbursed expenses for which any Secured Party is to be reimbursed pursuant to the Securities Purchase Agreement or Section 12 hereof; 18 second, to pay ratably the unpaid principal of the Secured Obligations; third, to pay ratably the unpaid interest accrued on the Secured Obligations in accordance with the provisions of the Bridge Securities and this Agreement; fourth, to pay ratably all other Secured Obligations, until all Secured Obligations shall have been paid in full; and finally, to pay to the Company or its successors or assigns, or as a court of competent jurisdiction may direct, any surplus then remaining from such proceeds. The Collateral Agent may make distributions hereunder in cash or in kind or, on a ratable basis, in any combination thereof. SECTION 10. Concerning the Collateral Agent. (a) The Collateral Agent is authorized to take all such action as is provided to be taken by it as Collateral Agent hereunder and all other action reasonably incidental thereto. As to any matters not expressly provided for herein (including, without limitation, the timing and methods of realization upon the Collateral) the Collateral Agent shall act or refrain from acting in accordance with written instructions from the Required Purchasers or, in the absence of such instructions, in accordance with its discretion. (b) The Collateral Agent shall not be responsible for the existence, genuineness or value of any of the Collateral or for the validity, perfection, priority or enforceability of the Security Interests in any of the Collateral, whether impaired by operation of law or by reason of any action or omission to act on its part hereunder. The Collateral Agent shall have no duty to ascertain or inquire as to the performance or observance of any of the terms of this Agreement by the Company. (c) BankAmerica Ventures and its affiliates may accept deposits from, lend money to, and generally engage in any kind of business with the Company or any subsidiary or affiliate of the Company as if it were not the Collateral Agent hereunder. (d) The obligations of the Collateral Agent hereunder are only those expressly set forth herein. without limiting the generality of the foregoing, the Collateral Agent shall not be required to take any action with respect to any Event of Default, except as expressly provided herein. 19 (e) The Collateral Agent may consult with legal counsel, independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken by it in good faith in accordance with the advice of such counsel, accountants or experts. (f) Neither the Collateral Agent nor any director, officer, agent, or employee of the Collateral Agent shall be liable for any action taken or not taken by it in connection herewith (i) with the consent or at the request of any Purchaser of any requests made in accordance with Section 10(a), the Required Purchaser or (ii) in the absence of its own gross negligence or willful misconduct. Neither the Collateral Agent, nor any of its affiliates, nor any of their respective directors, officers, agents or employees, shall be responsible for or have any duty to ascertain, inquire into or verify (i) any statement, warranty or representation made in connection with this Agreement; (ii) the performance or observance of any of the covenants or agreements of the Company; or (iii) the validity, effectiveness or genuiness of this Agreement or any instrument or writing furnished in connection herewith. The Collateral Agent shall not incur any liability by acting in reliance upon any notice, consent, certificate, statement, or other writing (which may be a bank wire, telex or similar writing) believed by it to be genuine or to be signed by the proper party or parties. The Collateral Agent shall not be responsible for the existence, genuiness or value of any of the Collateral. The Collateral Agent shall have no duty to ascertain or inquire as to the performance or observance of any of the terms of this Agreement by the Company. (g) Each Secured Party shall, ratably in accordance with the amount of its Obligations, indemnify the Collateral Agent, its affiliates and their respective directors, officers, agents and employees (to the extent not reimbursed by the Assignor) against any cost, expense (including counsel fees and disbursements), claim, demand, action, loss or liability (except such as result from the indemnitees' gross negligence or willful misconduct) that such indemnitees may suffer or incur in connection with this Agreement or any action taken or omitted by such indemnitees hereunder or thereunder. (h) The Collateral Agent may resign at any time by giving written notice of its resignation to the Secured Parties and the Company. Upon any such resignation, the Purchasers shall have the right to appoint a successor Collateral Agent (a "Successor Agent"). If no Successor Agent shall have been so appointed by the Purchasers, and shall have accepted such appointment, within 30 days after the retiring Security Agent's giving 20 of notice of resignation, then the retiring Collateral Agent may, on behalf of the Secured Parties, appoint a Successor Agent. Upon the acceptance of its appointment as Collateral Agent hereunder by a Successor Agent, such Successor Agent shall thereupon succeed to and become vested with all the rights and duties of the retiring Collateral Agent, and the retiring Security Agent shall be discharged from its duties and obligations hereunder. After any retiring Collateral Agent's resignation hereunder as Collateral Agent, the provisions of this Section shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Collateral Agent. (i) In order to comply with any legal requirement in any jurisdiction, the Collateral Agent may at any time appoint another bank or trust company or one or more other persons, either to act as co-agent or co-agents, jointly with the Collateral Agent, or to act as separate agent or agents on behalf of the Secured Parties with such power and authority as may be necessary for the effectual operation of the provisions hereof and may be specified in the instrument of appointment (which may, in the discretion of the Collateral Agent, include provisions for the protection of such co-agent or separate agent similar to the provisions of this Section 10). (j) Each Purchaser irrevocably appoints and authorizes the Collateral Agent to enter into and act as its agent in connection with the Financing Documents and to take such action as agent on its behalf and to exercise such powers under the Financing Documents as are delegated to it by the terms hereof or thereof, together with such powers as are incidental thereto. SECTION 11. Expenses. If the Company fails to comply with the provisions of the Bridge Securities or this Agreement, such that the value of any Collateral or the validity, perfection, rank or value of any Security Interest is thereby diminished or potentially diminished or put at risk, the Collateral Agent if requested by the Required Purchasers may, but shall not be required to, effect such compliance on behalf of the Company, and the Company shall reimburse the Collateral Agent for the costs thereof on demand. All insurance expenses and all expenses of protecting, storing, warehousing, appraising, insuring, handling, maintaining, and shipping the Collateral, any and all excise, property, sales, and use taxes imposed by any state, federal, or local authority on any of the Collateral, or in respect of periodic appraisals and inspections of the Collateral to the extent the same may be requested by the Required Purchasers from time to time, or in respect of the sale or other disposition thereof shall be borne and paid by the Company; and if the Company fails to promptly pay any portion thereof when 21 due, any Secured Party may, at its option, but shall not be required to, pay the same and charge the Company's account therefor, and the Company agrees to reimburse such Secured Party therefor on demand. All sums so paid or incurred by any Secured Party for any of the foregoing and any and all other sums for which the Company may become liable hereunder and all costs and expenses (including attorneys' fees, legal expenses and court costs) reasonably incurred by any Secured Party in enforcing or protecting the Security Interests or any of their rights or remedies under this Agreement, shall, together with interest thereon until paid at the rate otherwise applicable to the Bridge Securities plus 5%, be additional Secured Obligations hereunder. SECTION 12. Termination of Security Interests; Release of Collateral. Upon the repayment in full of all Secured Obligations, the Security Interests shall terminate and all rights to the Collateral shall revert to the Company. At any time and from time to time prior to such termination of the Security Interests, the Collateral Agent may release any of the Collateral with the prior written consent of the Required Purchasers. Upon any such termination of the Security Interests or release of Collateral, the Collateral Agent will, at the expense of the Company, execute and deliver to the Company such documents as the Company shall reasonably request to evidence the termination of the Security Interests or the release of such Collateral, as the case may be. SECTION 13. Notices. All notices, communications and distributions hereunder shall be given in accordance with Section 9.01 of the Securities Purchase Agreement. SECTION 14. Waivers, Non-Exclusive Remedies. No failure on the part of the Collateral Agent to exercise, and no delay in exercising and no course of dealing with respect to, any right under this Agreement shall operate as a waiver thereof; nor shall any single or partial exercise by the Collateral Agent of any right under the Credit Agreement or this Agreement preclude any other or further exercise thereof or the exercise of any other right. The rights in this Agreement and the Credit Agreement are cumulative and are not exclusive of any other remedies provided by law. SECTION 15. Successors and Assigns. This Agreement is for the benefit of the Secured Parties and their successors and assigns, and in the event of an assignment of all or any of the Secured Obligations, the rights hereunder, to the extent applicable to the indebtedness so assigned, shall be automatically transferred with such indebtedness. This Agreement shall be binding on the Company and its successors and assigns. 22 SECTION 16. Changes in Writing.

SECTION 17. California Law. This Agreement shall be construed in accordance with and governed by the laws of the State of California, except as otherwise required by mandatory provisions of law and except to the extent that remedies provided by the laws of any jurisdiction other than California are governed by the laws of such jurisdiction. SECTION 18. Severability. If any provision hereof is invalid or unenforceable in any jurisdiction, then, to the fullest extent permitted by law, (i) the other provisions hereof shall remain in full force and effect in such jurisdiction and shall be liberally construed in favor of the Secured Parties in order to carry out the intentions of the parties hereto as nearly as may be possible; and (ii) the invalidity or unenforceability of any provision hereof in any jurisdiction shall not affect the validity or enforceability of such provision in any other jurisdiction. 23 IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed by their respective authorized officers as of the day and year first above written.

EXHIBIT B OPINION OF COUNSEL FOR COMPANY 1. The Security Agreement creates a valid security interest, for the benefit of the Secured Parties, in all the Company's right, title and interest in all Collateral to the extent the UCC is applicable thereto (the "Security Interest"). 2. UCC financing statements and amendments thereto (collectively, the "Financing Statements") have been filed in the filing offices listed in Schedule 7 to the Perfection Certificate (the "Filing Jurisdictions"), which are all of the offices in which filings are required to perfect the Security Interest, to the extent the Security Interest may be perfected by filing under the UCC, and no further filing or recording of any document or instrument or other action will be required so to perfect the Security Interest, except that (i) continuation statements with respect to each Financing Statement must be filed within the respective time periods specified in Schedule 7 to the Perfection Certificate; (ii) additional filings may be necessary if the Company changes its name, identity or corporate structure or the jurisdiction in which its places of business, its chief executive office or the Collateral are located; and (iii) we express no opinion on the perfection of, or need for further filing or recording to perfect, the Security Interest in goods now or hereafter located in any jurisdiction other than the Filing Jurisdictions. 3. There are (a) no UCC financing statements which name the Company as debtor or seller and cover any of the Collateral, other than the Financing Statements, [and the financing statements with respect to Permitted Liens annexed as Schedule 5(A) to the Perfection Certificate], listed in the available records in the UCC filing offices specified in paragraphs 2 and 3 of the Perfection Certificate, which include all of the offices prescribed under the UCC as the offices in which filings should have been made to perfect security interests in the Collateral; and (b) no notices of the filing of any federal tax lien (filed pursuant to Section 6323 of the Internal Revenue Code) or any lien of the Pension Benefit Guaranty Corporation (filed pursuant to Section 4068 of ERISA) covering any of the Collateral listed in the available records in the [UCC filing office in state of Company's chief executive office], which is the only office having files which must be searched in order to fully determine the existence of notices of the filing of federal tax liens (filed pursuant to Section 6323 of the Internal Revenue Code) and liens of the Pension Benefit Guaranty Corporation (filed pursuant to Section 4068 of ERISA) on the Collateral. 4. The Security Interest validly secures the payment of all future Loans made by the Lenders to the Company, whether or not at the time such Loans are made an Event of Default or other event not within the control of the Lenders has relieved or may relieve the Lenders from their obligations to make such Loans, and is perfected to the extent specified in paragraph 7 above with respect to such future Loans. Insofar as the priority thereof is governed by the UCC, the Security Interest has the same priority with respect to such future Loans as it does with respect to Loans made on the date hereof. 2 EXHIBIT C [FORM OF LOCKBOX LETTER] _____________ __, 19__ [Name and Address of Lockbox Bank] Re: Cardiac Pathway Corporation Gentlemen: We hereby notify you that effective ___________, 19__, we have transferred exclusive ownership and control of our lock-box account[s] No[s]. _________________ (the "Lockbox Account[s]") maintained with you under the terms of the [Lockbox Agreement] attached hereto as Exhibit A (the "Lockbox Account[s]") to [______________________________], as Collateral Agent (the "Collateral Agent").
