Accelerating the trend towards less invasive procedures. Four major trends are driving the demand for less invasive cardiovascular procedures: improved non-invasive diagnostic and therapeutic techniques; cost-containment pressures from payors; increasing incidence of vascular and structural heart disease; and patient demand for less invasive procedures which require shorter hospital stays and allow more rapid recovery. This shift to less invasive procedures requires diagnostic modalities that can provide more comprehensive clinical information than angiography. Our IVUS products offer continuous, real-time, three-dimensional imaging, plaque visualization, color-coded identification of plaque composition, and automatic drawing of lumen and plaque borders allowing for automatic vessel sizing. Our FM products offer physicians a simple pressure and flow based method to determine whether stenting or additional percutaneous intervention is required. We believe our combination of IVUS enhancements and functional assessment is instrumental in facilitating less invasive procedures

Exhibit 10.5

LOAN AND SECURITY AGREEMENT
(Equipment & Inventory)

     The Borrower and Lender identified on the cover page of this document have entered or anticipate entering into one or more transactions pursuant to which Lender agrees to make available to Borrower a loan facility governed by the terms and conditions set forth in this document and one or more Supplements executed by Borrower and Lender which incorporate this document by reference. Each Supplement constitutes a supplement to and forms part of this document, and will be read and construed as one with this document, so that this document and the Supplement constitute a single agreement between the parties (collectively referred to as this “Agreement”).

     Accordingly, the parties agree as follows:

ARTICLE 1 — INTERPRETATION

     1.1 Definitions. The terms defined in Article 10 and in the Supplement will have the meanings therein specified for purposes of this Agreement.

     1.2 Inconsistency. In the event of any inconsistency between the provisions of any Supplement and this document, the provisions of the Supplement will be controlling for the purpose of all relevant transactions.

ARTICLE 2 — THE COMMITMENT AND LOANS

     2.1 The Commitment. Subject to the terms and conditions of this Agreement, Lender agrees to make term loans to Borrower from time to time from the Closing Date and to, but not including, the Termination Date in an aggregate principal amount not exceeding the Commitment, for the purpose of financing the acquisition or carrying of certain Equipment and Inventory. The Commitment is not a revolving credit commitment, and Borrower does not have the right to repay and reborrow hereunder. Each Loan requested by Borrower to be made on a single Business Day shall be for a minimum principal amount set forth in the Supplement, except to the extent the remaining Commitment is a lesser amount.

     2.2 Notes Evidencing Loans; Repayment. Each Loan shall be evidenced by a separate Note payable to the order of Lender, in the total principal amount of the Loan. Principal and interest of each Loan shall be payable at the times and in the manner set forth in the Note and payment shall be effected by automatic debit of the appropriate funds from Borrower’s Primary Operating Account as specified in the Supplement hereto.

     2.3 Procedures for Borrowing.

     (a) Borrower shall give Lender, at least five (5) Business Days’ prior to a proposed Borrowing Date, written notice of any request for borrowing hereunder (a “Borrowing Request”). Each Borrowing Request shall be in substantially the form of Exhibit “B” to the Supplement, shall be executed by a responsible executive or financial officer of Borrower, and shall state how much is requested, and shall be accompanied by such other information and documentation as Lender may reasonably request.

     (b) No later than 1:00 p.m. Pacific Standard Time on the Borrowing Date, if Borrower has satisfied the conditions precedent in Article 4, Lender shall make the Loan available to Borrower in immediately available funds.

     2.4 Interest. Basic Interest on the outstanding principal balance of each Loan shall accrue daily at the Designated Rate from the Borrowing Date until the Maturity Date. If the outstanding principal balance of such Loan is not paid on the Maturity Date, interest shall accrue at the Default Rate until paid in full, as further set forth herein.

     2.5 Terminal Payment. Borrower shall pay the Terminal Payment with respect to each Loan on the Maturity Date of such Loan.

     2.6 Interest Rate Calculation. Basic Interest, along with charges and fees under this Agreement and any Loan Document, shall be calculated for actual days elapsed on the basis of a 360-day year, which results in higher interest, charge or fee payments than if a 365-day year were used. In no event shall Borrower be obligated to pay Lender interest, charges or fees at a rate in excess of the highest rate permitted by applicable law from time to time in effect.

     2.7 Default Interest. Any unpaid payments of principal or interest or the Terminal Payment with respect to any Loan shall bear interest from their respective maturities, whether scheduled or accelerated, at the Designated Rate for such Loan plus five percent (5.00%) per annum, until paid in full, whether before or after judgment (the “Default Rate”). Borrower shall pay such interest on demand.

     2.8 Late Charges. If Borrower is late in making any payment of principal or interest or Terminal Payment under this Agreement by more than five (5) days, Borrower agrees to pay a late charge of five percent (5%) of the installment due, but not less than fifty dollars ($50.00) for any one such delinquent payment. This late charge may be charged by Lender for the purpose of defraying the expenses incidental to the handling of such delinquent amounts. Borrower acknowledges that such late charge represents a reasonable sum considering all of the circumstances existing on the date of this Agreement and represents a fair and reasonable estimate of the costs that will be sustained by Lender due to the failure of Borrower to make timely payments. Borrower further agrees that proof of actual damages would be costly and inconvenient. Such late charge shall be paid without prejudice to the right of Lender to collect any other amounts provided to be paid or to declare a default under this Agreement or any of the other Loan Documents or from exercising any other rights and remedies of Lender.

     2.9 Lender’s Records. Principal, Basic Interest,Terminal Payments and all other sums owed under any Loan Document shall be evidenced by entries in records maintained by Lender for such purpose. Each payment on and any other credits with respect to principal, Basic Interest, Terminal Payments and all other sums outstanding under any Loan Document shall be evidenced by entries in such records. Absent manifest error, Lender’s records shall be conclusive evidence thereof.

     2.10 Grant of Security Interests; Filing of Financing Statements. To secure the timely payment and performance of all of Borrower’s Obligations to Lender, Borrower hereby grants to Lender continuing security interests in all of the Collateral. In connection with the foregoing, Borrower authorizes Lender to prepare and file any financing statements describing the Collateral without otherwise obtaining the Borrower’s signature or consent with respect to the filing of such financing statements.

     7.3 Sale of Collateral. Upon the occurrence and during the continuance of an Event of Default, Lender may sell all or any part of the Collateral, at public or private sales, to itself, a wholesaler, retailer or investor,for cash, upon credit or for future delivery, and at such price or prices as Lender may deem commercially reasonable.

Without having any obligation to do so, upon reasonable prior notice to Borrower, Lender may perform or pay any obligation which Borrower has agreed to perform or pay under this Agreement, including, without limitation, the payment or discharge of taxes or Liens levied or placed on or threatened against the Collateral. In so performing or paying, Lender shall determine the action to be taken and the amount necessary to discharge such obligations. Borrower shall reimburse Lender on demand for any amounts paid by Lender pursuant to this Section, which amounts shall constitute Obligations secured by the Collateral and shall bear interest from the date of demand at the Default Rate.

For the purpose of protecting and preserving the Collateral and Lender’s rights under this Agreement, Borrower hereby irrevocably appoints Lender, with full power of substitution, as its attorney-in-fact with full power and authority, after the occurrence and during the continuance of an Event of Default, to do any act which Borrower is obligated to do hereunder; to exercise such rights with respect to the Collateral as Borrower might exercise; to use such Equipment, Fixtures or other property as Borrower might use; to enter Borrower’s premises; to give notice of Lender’s security interest in, and to collect the Collateral; and to execute and file in Borrower’s name any financing statements, amendments and continuation statements necessary or desirable to perfect or continue the perfection of Lender’s security interests in the Collateral.

     8.3 Authorization for Lender to Take Certain Action. The power of attorney created in Section 8.2 is a power coupled with an interest and shall be irrevocable. The powers conferred on Lender hereunder are solely to protect its interests in the Collateral and shall not impose any duty upon Lender to exercise such powers. Lender shall be accountable only for amounts that it actually receives as a result of the exercise of such powers and in no event shall Lender or any of its directors, officers, employees, agents or representatives be responsible to Borrower for any act or failure to act, except for gross negligence or willful misconduct. After the occurrence and during the continuance of an Event of Default, Lender may exercise this power of attorney without notice to or assent of Borrower, in the name of Borrower, or in Lender’s own name, from time to time in Lender’s sole discretion and at Borrower’s expense. To further carry out the terms of this Agreement, after the occurrence and during the continuance of an Event of Default, Lender may:

     (a) Execute any statements or documents or take possession of, and endorse and collect and receive delivery or payment of, any checks, drafts, notes, acceptances or other instruments and documents constituting Collateral, or constituting the payment of amounts due and to become due or any performance to be rendered with respect to the Collateral.

     (e) Commence, prosecute or defend any suits, actions or proceedings or as otherwise deemed appropriate by Lender for the purpose of protecting or collecting the Collateral.

     (f) Prepare, adjust, execute, deliver and receive payment under insurance claims, and collect and receive payment of and endorse any instrument in payment of loss or returned premiums or any other insurance refund or return, and apply such amounts at Lender’s sole discretion, toward repayment of the Obligations or replacement of the Collateral.

     8.4 Application of Proceeds. Any Proceeds and other monies or property received by Lender pursuant to the terms of this Agreement or any Loan Document may be applied by Lender first to the payment of expenses of collection, including without limitation reasonable attorneys’ fees, and then to the payment of the Obligations in such order of application as Lender may elect.

     8.5 Deficiency. If the Proceeds of any disposition of the Collateral are insufficient to cover all costs and expenses of such sale and the payment in full of all the Obligations, plus all other sums required to be expended or distributed by Lender, then Borrower shall be liable for any such deficiency.

     8.6 Lender Transfer. Upon the transfer of all or any part of the Obligations, Lender may transfer all or part of the Collateral and shall be fully discharged thereafter from all liability and responsibility with respect to such Collateral so transferred, and the transferee shall be vested with all the rights and powers of Lender hereunder with respect to such Collateral so transferred, but with respect to any Collateral not so transferred, Lender shall retain all rights and powers hereby given.

     8.7 Lender’s Duties.

     (a) Lender shall use reasonable care in the custody and preservation of any Collateral in its possession. Without limitation on other conduct which may be considered the exercise of reasonable care, Lender shall be deemed to have exercised reasonable care in the custody and preservation of such Collateral if such Collateral is accorded treatment substantially equal to that which Lender accords its own property, it being understood that Lender shall not have any responsibility for ascertaining or taking action with respect to declining value or other matters relative to any Collateral, regardless of whether Lender has or is deemed to have knowledge of such matters; or taking any necessary steps to preserve any rights against any Person with respect to any Collateral. Under no circumstances shall Lender be responsible for any injury or loss to the Collateral, or any part thereof, arising from any cause beyond the reasonable control of Lender.

     (b) Lender may at any time deliver the Collateral or any part thereof to Borrower and the receipt of Borrower shall be a complete and full acquittance for the Collateral so delivered, and Lender shall thereafter be discharged from any liability or responsibility therefor.

     (c) Neither Lender, nor any of its directors, officers, employees, agents, attorneys or any other person affiliated with or representing Lender shall be liable for any claims, demands, losses or damages, of any kind whatsoever, made, claimed, incurred or suffered by Borrower or any other party through the ordinary negligence of Lender, or any of its directors, officers, employees, agents, attorneys or any other person affiliated with or representing Lender.

     8.8 Termination of Security Interests. Upon the payment in full of the Obligations and satisfaction of all Borrower’s obligations under this Agreement and the other Loan Documents, and if Lender has no further obligations under its Commitment, the security interest granted hereby shall terminate and all rights to the Collateral shall revert to Borrower. Upon any such termination, the Lender shall, at Borrower’s expense, execute and deliver to Borrower such documents as Borrower shall reasonably request to evidence such termination.

are to be sent by giving written notice of such change to each other party. Notice given by hand delivery shall be deemed received on the date delivered; if sent by overnight courier, on the next business day after delivery to the courier service; if by first class mail, on the third business day after deposit in the U.S. Mail; and if by facsimile, on the date of transmission.

     9.2 Binding Effect. The Loan Documents shall be binding upon and inure to the benefit of Borrower and Lender and their respective successors and assigns; provided, however, that Borrower may not assign or transfer Borrower’s rights or obligations under any Loan Document without Lender’s prior written consent. Lender reserves the right to sell, assign, transfer, negotiate or grant participations in all or any part of, or any interest in, Lender’s rights and obligations under the Loan Documents. In connection with any of the foregoing, Lender may disclose all documents and information which Lender now or hereafter may have relating to the Loans, Borrower, or its business; provided that any person who receives such information shall have agreed in writing in advance to maintain the confidentiality of such information on terms reasonably acceptable to Borrower.

To that end the references to Lender in Sections 4.2(f), 5.1, 5.2, 5.3, and 5.9(a) hereof shall include LLC and LLC shall have the right to exercise the advisory inspection, information and other rights given to lender under those Sections independently of Lender. No amendment on modification of this Agreement shall alter or diminish LLC’s rights under the preceding sentence without the consent of LLC.

Any waiver, consent or approval by Lender of any Event of Default or breach of any provision, condition, or covenant of any Loan Document must be in writing and shall be effective only to the extent set forth in writing.

No failure or delay on the part of Lender in exercising any power, right, or privilege under any Loan Document shall operate as a waiver thereof, and no single or partial exercise of any such power, right, or privilege shall preclude any further exercise thereof or the exercise of any other power, right or privilege. Lender has the right at its sole option to continue to accept interest and/or principal payments due under the Loan Documents after default, and such acceptance shall not constitute a waiver of said default or an extension of the Maturity Date unless Lender agrees otherwise in writing.

     9.4 Rights Cumulative. All rights and remedies existing under the Loan Documents are cumulative to, and not exclusive of, any other rights or remedies available under contract or applicable law.

     9.5 Unenforceable Provisions. Any provision of any Loan Document executed by Borrower which is prohibited or unenforceable in any jurisdiction, shall be so only as to such jurisdiction and only to the extent of such prohibition or unenforceability, but all the remaining provisions of any such Loan Document shall remain valid and enforceable.

     9.6 Accounting Terms. Except as otherwise provided in this Agreement, accounting terms and financial covenants and information shall be determined and prepared in accordance with GAAP.

This indemnification shall survive the payment and satisfaction of all of Borrower’s Obligations to Lender.

     9.8 Reimbursement. Borrower shall reimburse Lender for all costs and expenses, including without limitation reasonable attorneys’ fees and disbursements expended or incurred by Lender in any arbitration, mediation, judicial reference, legal action or otherwise in connection with (a) the preparation and negotiation of the Loan Documents, (b) the amendment and enforcement of the Loan Documents, including without limitation during any workout, attempted workout, and/or in connection with the rendering of legal advice as to Lender’s rights, remedies and obligations under

the Loan Documents, (c) collecting any sum which becomes due Lender under any Loan Document, (d) any proceeding for declaratory relief, any counterclaim to any proceeding, or any appeal, or (e) the protection, preservation or enforcement of any rights of Lender.
