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

          Section 10.3 Remedies Cumulative. No remedy conferred herein or in the Notes or any other Note Document upon the Purchasers is intended to be exclusive of any other remedy and each and every such remedy shall be cumulative and shall be in addition to every other remedy given hereunder or now or hereafter existing at law or in equity or otherwise.

          Section 10.4 Remedies Not Waived.

The Issuer will keep at its principal executive office a register, in which, subject to such reasonable regulations as it may prescribe, but at its expense (other than transfer taxes, if any), the Issuer will provide for the registration and transfer of its Notes. Whenever any Note or Notes shall be surrendered by a Purchaser either at the principal executive office of the Issuer, or at the place of payment named in the Note, for transfer or exchange, accompanied (if so required by the Issuer) by a written instrument of transfer in form reasonably satisfactory to the Issuer duly executed by such Purchaser or by such Purchaser’s attorney duly authorized in writing, the Issuer will execute and deliver in

exchange therefor a new Note or Notes in such denominations as may be requested by such Purchaser, of like tenor and in the same aggregate unpaid principal amount as the aggregate unpaid principal amount of the Note or Notes so surrendered. Any Note issued in exchange for any other Note or upon transfer thereof shall carry the rights to unpaid interest and interest to accrue which were carried by the Note so exchanged or transferred, and neither gain nor loss of interest shall result from any such transfer or exchange. Any transfer tax or governmental charge relating to such transaction shall be paid by the Purchaser requesting the exchange. The Issuer and any of its agents may treat the Person in whose name any Note is registered as the sole and exclusive record and beneficial Purchaser and owner of such Note for the purpose of receiving payment of the principal of, prepayment charge (if any) and interest and other amounts on such Note and for all other purposes whatsoever, whether or not such Note be overdue.

At the request of any Purchaser, the Issuer will issue and deliver at their expense, in replacement of any Note or Notes issued by the Issuer lost, stolen, damaged or destroyed, upon surrender thereof, if mutilated, a new Note or Notes in the same aggregate unpaid principal amount, and otherwise of the same tenor, as the Note or Notes so lost, stolen, damaged or destroyed, duly executed by the Issuer. The Issuer may condition the replacement of a Note or Notes reported by the Purchaser thereof as lost, stolen, damaged or destroyed, upon the receipt from such Purchaser of an indemnity and/or security reasonably satisfactory to the Issuer; provided that if such Purchaser shall be FFC Partners II, L.P., FFC Executive Partners II, L.P. or nominee thereof, such Purchaser’s unsecured agreement of indemnity shall be sufficient for purposes of this Section.

     Section 13. Miscellaneous.

          Section 13.1 Amendment and Waiver.

          (a) No amendment or waiver of any provision of this Agreement, the Notes or any other Note Document, or any consent to any departure by any Credit Party, shall in any event be effective unless the same shall be in writing and signed by the Required Purchasers and the Issuer. Any such waiver or consent shall be effective only in the specific instance and for the purpose for which given. Neither any failure nor any delay on the part of the Purchasers in exercising any right, power or privilege hereunder or under the Notes or any of the Note Documents shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege.

on, or fees payable with respect to, any of the Notes, (iii) reduce the percentage of the Notes required with respect to any such amendment or to effectuate any such waiver or consent, or modify the definitions herein of the term “Required Purchasers”, or (iv) modify any provision of this Section 13.1.

All representations and warranties contained herein or made in writing by or on behalf of any party to this Agreement or otherwise in connection herewith, shall (i) survive the execution and delivery of this Agreement and the delivery of the Notes and Warrants to the Purchasers and shall continue in effect until all of the Obligations have been indefeasibly paid in full and no Notes are outstanding, and thereafter as provided in Section 13.5 with respect to the obligations imposed thereunder, and (ii) be deemed to be material and to have been relied upon by the Purchasers, regardless of any investigation made by the Purchasers or on their behalf.

Upon execution and delivery of such an instrument, such Assignee shall be a party to this Agreement and shall have the rights and obligations of a Purchaser (including its rights under this Section 13.3(b)), to the extent of such assignment, and the Assignor shall be released from its obligations hereunder to a corresponding extent. Upon the consummation of any assignment by the Assignor pursuant to this Section 13.3(b), the Assignor and the Issuer shall make appropriate arrangements so that, if required, new Notes shall be issued to the Assignor and the Assignee. The Assignor shall give the Issuer prior written notice of the date that any such assignment shall become effective, which date shall be no less than ten days after the date such notice is given.

or returned, the Obligations shall be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned.
