ARTICLE 5.
RIGHTS AND REMEDIES

     5.1 EVENT OF DEFAULT DEFINED. Any failure to materially comply with any covenant, agreement, term or provision contained in this Agreement, the Patent and Trademark Security Agreement (provided such failure continues through five days after the Secured party gives to Sutura written notice thereof) or any event of default under any of the Notes (including events of non-compliance with this Agreement, as described in the Notes) shall constitute an “Event of Default” hereunder. Without limiting the foregoing, it is intended that any event of default under the any of the Notes or the Synapse Note will constitute an event of default under each of the Notes and the Synapse Note

               (i) proceed to protect and enforce the respective rights vested in it by this Agreement and under the UCC;

               (ii) cause all moneys and other property pledged as security to Secured Party to be paid and/or delivered directly to such Secured Party, and demand, ▇▇▇ for, collect and receive any such moneys and property;

               (iii) cause any action at law or suit in equity or other proceeding to be instituted and prosecuted to collect or enforce any Obligations of Sutura or rights included in the Collateral, or for specific enforcement of any covenant or agreement contained herein, or in aid of the exercise of any power therein or herein granted, or for any foreclosure hereunder and sale under a judgment or decree in any judicial proceeding, or to enforce any other legal or equitable right vested in it by this Agreement or by law;

               (iv) foreclose or enforce any other agreement or other instrument by or under or pursuant to which the Obligations of Sutura are issued or secured;

               (v) subject to Section 5.2(b), sell, lease or otherwise dispose of any or all of the Collateral, in one or more transactions, at such prices as such Secured Party may deem best, and for cash or on credit or for future delivery, without assumption of any credit risk, at any broker’s board or at public or private sale, without demand of performance or notice of intention to sell, lease or otherwise dispose of, or of time or place of disposition (except such notice as is required by applicable statute and cannot be waived), it being agreed that Secured Party may be a purchaser or lessee on its own behalf at any such sale and that Secured Party or anyone else who may be the purchaser, lessee or recipient for value of any or all of the Collateral so disposed of shall, upon such disposition, acquire all of Sutura’s rights therein. Secured Party may 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 same, and such sale may, without further notice or publication, be made at any time or place to which the same may be so adjourned. If Secured Party sells any of the Collateral upon credit, after reasonable inquiry as to the credit worthiness of the purchaser, Sutura will be credited only with payments actually made by the purchaser, received by Secured Party and applied to the indebtedness of the purchaser. In the event the purchaser fails to pay for the Collateral, Secured Party may resell the Collateral and Sutura shall be credited with the proceeds of the sale;

               (vi) incur expenses, including reasonable attorneys’ fees, consultants’ fees, and other costs appropriate to the exercise of any of its rights or powers under this Agreement;

               (vii) perform any obligation of Sutura hereunder and make payments, purchase, contest or compromise any encumbrance, charge, or lien, and pay taxes and expenses;

               (viii) make any reasonable compromise or settlement deemed desirable with respect to any or all of the Collateral and extend the time of payment, arrange for payment installments, or otherwise modify the terms of, any or all of the Collateral;

               (ix) secure the appointment of a receiver of any or all of the Collateral;

               (x) exercise any other or additional rights or remedies granted to such Secured Party under any other provision of this Agreement or exercisable by a secured party under the UCC, whether or not the UCC applies to the affected Collateral, or under any other applicable law and take any other action which Secured Party deems necessary or desirable to protect or realize upon its respective security interest in the Collateral or any part thereof; and/or

               (xi) appoint a third party (who may be an employee, officer or other representative of Secured Party) to do any of the foregoing, or take any other action permitted hereunder, on behalf of such Secured Party.

     (b) If, pursuant to any law, prior notice of any action described in Section 5.2(a) is required to be given to Sutura, Sutura hereby acknowledges that the minimum time required by such law, or if no minimum is specified, ten days, shall be deemed a reasonable notice period.

     (c) Any action or proceeding to enforce this Agreement may be taken by Secured Party either in Sutura’s name or in Secured Party’s name, as each such Secured Party may deem necessary.

     (d) All rights of marshalling of assets of Sutura, including any such right with respect to the Collateral, are hereby waived by Sutura.

     (e) Secured Party shall incur no liability as a result of the sale of any or all of the Collateral at any private sale pursuant to Section 5.2(a) conducted in a commercially reasonable manner. Sutura hereby waives any claims against Secured Party arising by reason of the fact that the price at which any or all of the Collateral may have been sold at such a private sale was less than the price that might have obtained at a public sale or was less than the aggregate amount of the Obligations, even if Secured Party accepts the first offer received and does not offer the Collateral to more than one offeree.

     5.3 ATTORNEYS-IN-FACT. Upon the occurrence and during the continuation of an Event of Default, Sutura hereby irrevocably constitutes and appoints each Secured Party as its true and lawful attorneys-in-fact to enforce all rights of Sutura with respect to the Collateral, including the right to give appropriate receipts, releases and satisfactions for and on behalf of and in the name of Sutura or, at the option of such Secured Party, in the name of such Secured Party, with the same force and effect as Sutura could do if this Agreement had not been made. If Secured Party shall so elect after the occurrence and during the continuation of an Event of Default hereunder, Secured Party shall have the right at all times to settle, compromise, adjust, or liquidate all claims or disputes directly with Sutura or any obligor of Sutura upon such terms and conditions as each Secured Party may determine in its sole discretion, and to charge all costs and expenses thereof (including reasonable attorneys’ fees and charges) to Sutura’s account and to add them to the Obligations whereupon such costs and expenses shall be and become part of the Obligations. This power of attorney is a power coupled with an interest and shall be irrevocable.

     5.4 EXPENSES; INTEREST. All costs and expenses (including reasonable attorneys’ fees and expenses) incurred by each Secured Party in connection with exercising any actions taken under Article 5, together with interest thereon (to the extent permitted by law)

computed at a rate of 10% per annum (or if less, the maximum rate permitted by law) from the date on which such costs or expenses are invoiced to and become payable by Sutura, to the date of payment thereof, shall constitute part of the Obligations secured by this Agreement and shall be paid by Sutura to each such Secured Party within 10 days after written demand.

     5.5 NO IMPAIRMENT OF REMEDIES. If, under applicable law, Secured Party proceeds by either judicial foreclosure or by non-judicial sale or enforcement, such Secured Party may, at its sole option, determine which of its remedies or rights to pursue without affecting any of its rights and remedies under this Agreement. If, by exercising any right and remedy, Secured Party forfeits any of its other rights or remedies, including any right to enter a deficiency judgment against Sutura or any third party (whether because of any applicable law pertaining to “election of remedies” or the like), Sutura nevertheless hereby consents to such action by Secured Party. To the extent permitted by applicable law, Sutura also waives any claim based upon such action, even if such action by Secured Party results in a full or partial loss of any rights of subrogation, indemnification or reimbursement which Sutura might otherwise have had but for such action by Secured Party or the terms herein. Any election of remedies which results in the denial or impairment of the right of Secured Party to seek a deficiency judgment against any third party shall not, to the extent permitted by applicable law, impair Sutura’s obligations hereunder. If Secured Party bids at any foreclosure or trustee’s sale or at any private sale permitted by law or this Agreement, Secured Party may bid all or less than the amount of the Obligations. To the extent permitted by applicable law, the amount of the successful bid at any such sale, whether Secured Party or any other party is the successful bidder, shall be conclusively deemed to be the fair market value of the Collateral and the difference between such bid amount and the remaining balance of the Obligations shall be conclusively deemed to be the amount of the Obligations.

ARTICLE 6.
CERTAIN WAIVERS

     6.1 MODIFICATION OF OBLIGATIONS. Sutura’s liability hereunder shall not be reduced, limited, impaired, discharged or terminated if Secured Parties at any time with Sutura’s consent (or, to the extent permissible by the terms of the Loan Documents and law, without notice to or demand of Sutura):

     (g) exercise any other rights available to them under any of the Loan Documents, at law or in equity.

     6.2 SECURITY INTERESTS ABSOLUTE. All rights of Secured Parties and the security interests hereunder, and all obligations of Sutura hereunder, shall be absolute and unconditional irrespective of:

     (c) the application of payments received from any source (other than payments received from the proceeds of any security for any of the Obligations, except to the extent such security also serves as collateral for indebtedness other than the Obligations) to the payment of indebtedness of Sutura to Secured Party other than the Obligations, even though Secured Party might have elected to apply such payment to any part or all of the Obligations;

     (d) Secured Party’s consent to the change, reorganization or termination of the corporate structure or existence of Sutura and to any corresponding restructuring of any of the Obligations;

     (e) any other act or thing or omission, or delay to do any other act or thing, which may or might in any manner or to any extent vary the risk of Sutura as an obligor in respect of any of the Obligations;

     (f) any Obligations or any agreement relating thereto, at any time being found to be illegal, invalid or unenforceable in any respect; and

     (g) any defenses, set-offs or counterclaims which Sutura may allege or assert against Secured Party in respect of the Obligations.

     6.3 CERTAIN WAIVERS. Except as provided in Section 7.16, Sutura hereby waives any and all defenses afforded to a surety, including promptness, diligence, notice of acceptance and any other notice with respect to any of the Obligations and this Agreement and any requirement that Secured Parties protect, secure, perfect or insure any security interest or lien, or any property subject thereto, or exhaust any right or take any action against Sutura or any other third party or entity or any collateral securing any of the Obligations, as the case may be.

     6.4 POSTPONEMENT OF SUBROGATION. Sutura agrees that it will not exercise any rights which it may acquire by way of rights of subrogation under this Agreement, by any payment made hereunder or otherwise, while this Agreement is in effect, unless such action is required to stay or prevent the running of any applicable statute of limitations. Any amount paid to Sutura on account of any such subrogation rights prior to such time shall be held in trust for Secured Parties and shall immediately be paid to Secured Parties and credited and applied against the Obligations. Any time after this Agreement has terminated and if Sutura has made payment to Secured Parties of all of the Obligations, or if an action is required to stay or prevent the running of any applicable statute of limitations, then, at Sutura’s request, Secured Parties will execute and deliver to Sutura appropriate documents (without recourse and without representation or warranty) necessary to evidence the transfer by subrogation to Sutura of an interest in the Obligations resulting from such payment by Sutura.

     7.16 LIMITATION ON DUTY OF SECURED PARTY WITH RESPECT TO THE COLLATERAL. The powers conferred on each Secured Party hereunder are solely to protect its respective interests in the Collateral and shall not impose any duty on such Secured Party or any of its designated agents to exercise any such powers. Except for the safe custody of any Collateral in their possession and the accounting for monies actually received by them hereunder, Secured Parties shall have no duty with respect to any Collateral and no implied duties or obligations shall be read into this Agreement against Secured Parties. Each Secured Party shall be deemed to have exercised reasonable care in the custody and preservation of the Collateral in its possession if the Collateral is accorded treatment that is substantially equivalent to that which such Secured Party accords its own respective property, it being expressly agreed, to the maximum extent permitted by applicable law, that each Secured Party shall have no responsibility for (a) taking any necessary steps to preserve rights against any parties with respect to any Collateral or (b) taking any action to protect against any diminution in value of the Collateral, but, in each case, each Secured Party may do so and all expenses reasonably incurred in connection therewith shall be part of the Obligations.

     7.17 COLLECTION AGENT. The following shall relate to the enforcement of this Agreement:

     (a) The Secured Parties hereby appoint Whitebox Advisors, LLC as the initial collection agent and attorney-in-fact for the Secured Parties under this Agreement (in such capacity, the "Collection Agent”) to serve from the date hereof until the termination hereof, or until the Collection Agent’s successor is duly appointed by agreement among the Secured Parties and their successors in interest and the Secured Parties and their successors in interest notify

Sutura in writing of the newly appointed successor Collection Agent. Each Secured Party hereby authorizes the Collection Agent to act as exclusive agent of and for all Secured Parties for purposes of taking any action to enforce rights and foreclose and dispose of any Collateral under this Agreement and the Patent and Trademark Security Agreement (together, the “Security Agreements”). Each Secured Party agrees that it shall not take any action against Sutura to enforce rights under the Security Agreements and foreclose and dispose of any Collateral, except through and as directed by the Collection Agent.

     (b) Each Secured Party hereby irrevocably authorizes the Collection Agent to take such action and to exercise such powers hereunder as provided herein or as requested in writing by any of the Secured Parties. The Collection Agent may rely upon advice of counsel concerning legal matters, advice of certified public accountants with respect to accounting matters and advice of other experts as to any other ▇▇▇▇▇▇ which it reasonably believes to be genuine or to have been presented by an appropriate person under the circumstances. The Collection Agent may execute any of its duties hereunder by or through agents or employees and shall be entitled to request and act in reliance upon the advice of counsel concerning all matters pertaining to its duties hereunder and shall not be liable for any action taken or omitted to be taken by it in good faith in accordance therewith. The Collection Agent may take any and all actions that the Collection Agent deems necessary or appropriate, in its reasonable discretion, in exercising its powers hereunder, including, but not limited to, initiating any action in the name of the Secured Parties against Sutura, foreclosing on the Collateral or exercising any other rights available to the Collection Agent on behalf of the Secured Parties at law or in equity.

     (c) Each Secured Party acknowledges and agrees as follows: (i) prior to declaring any event of Default hereunder and/or under the Notes and the Synapse Note or proceeding against any Collateral to enforce collection under the Notes or the Synapse Notes, such Secured Party will provide thirty (30) days prior written notice (“Secured Party Notice”) to each of the other Secured Parties and the Collection Agent; or (ii) following any Secured Party Notice, and then for so long as Sutura remains in default hereunder and/or under any of the Notes or Synapse Note, any amounts collected as payment and performance of the Obligations (whether collected by any Secured Party or the Collection Agent) shall be disbursed on a pro rata basis to each Secured Party based on the relative amounts due each such Secured Party under its respective note(s) (including, without limitation, interest) as such amount bears to the total amounts due to all Secured Parties under all such notes on an aggregate basis (including, without limitation, interest).

     (d) Sutura may rely on all orders and directions of the Collection Agent appointed under subsection (a) above as acting on behalf, and with the authority, of the Secured Parties, or any of them, without liability to any Secured Party or its successors in interest.

     7.18 SYNAPSE AS AGENT. Sutura acknowledges that Synapse is executing this Agreement as agent for certain other parties which and who are parties to a Settlement Agreement with Sutura dated as of an even date herewith. Synapse represents to Sutura that it has the authority to enter into this Agreement and that Sutura may rely on any act of, or notice by, Synapse hereunder as the act and notice of all parties for which and whom it is acting as agent.
