After reasonable inquiry of its officers and employees, the Company is not aware of any fact which might result in or form the basis for any such action, suit, arbitration, investigation, inquiry or other proceeding. Except as set forth on Schedule 3.10, neither the Company nor any Subsidiary is subject to any order, writ, judgment, injunction, decree, determination or award of any court or of any governmental agency or instrumentality (whether federal, state, local or foreign).

(k) Absence of Undisclosed Liabilities

Neither the Company nor any of its Subsidiaries has any debt, obligation or liability (whether accrued, absolute, contingent, liquidated or otherwise, whether due or to become due, whether or not known to the Company) arising out of any transaction entered into at or prior to either Closing, or any act or omission at or prior to either Closing, or any state of facts existing at or prior to either Closing, including taxes with respect to or based upon the transactions or events occurring at or prior to either Closing, and including, without limitation, unfunded past service liabilities under any pension, profit sharing or similar plan, except for liabilities disclosed in the financial statements included in the Company’s SEC Reports and liabilities incurred in the usual and ordinary course of business subsequent to September 28, 2003 and liabilities of the type not required under GAAP to be reflected in such financial statements, none of which liabilities incurred subsequent to September 28, 2003 (individually or in the aggregate) could reasonably be expected to have a Material Adverse Effect.

(l) Change in Ownership

Neither (a) the purchase of the Exchangeable Notes by the Investors, (b) the issuance of the Second Closing Shares to the Investors nor (c) the consummation of the transactions contemplated by this Agreement will result in (i) any material adverse change in the business operations of the Company or any of its Subsidiaries, (ii) the acceleration of the vesting of any outstanding option, warrant, call, commitment, agreement, conversion right, preemptive right or other right to subscribe for, purchase or otherwise acquire any of the shares of the capital stock of the Company or any of the stock of the Company or any of its Subsidiaries, or debt securities of the Company or any of its Subsidiaries (collectively “Commitments”, and each individually a “Commitment”), (iii) any obligation of the Company to grant, extend or enter into any Commitment, or (iv) any right in favor of any Person to terminate or cancel any Key Agreement or Instrument.

(m) Employment Matters

(i) The Company and its Subsidiaries are in compliance with all federal, state, local and foreign laws and regulations respecting employment and employment practices, terms and conditions of employment and wages and hours, as applicable, except where failure to be in compliance would not have a Material Adverse Effect. The Company is not bound by or subject to (and none of its assets or properties is bound by or subject to) any written or oral, express or implied, contract, commitment or arrangement with any labor union, and no labor union has requested or, to the Company’s knowledge, has sought to represent any of the employees, representatives or agents of the Company.

(ii) The Company and its Subsidiaries have no employee benefit plans (as defined in Section 3(3) of the Employee Retirement Income Security Act of 1974) covering former or current employees of the Company or any of its Subsidiaries, or under which the Company or any of its Subsidiaries has any obligation or liability other than withholding obligations.

(iii) The transactions contemplated by this Agreement will not cause the acceleration of the vesting of any options or other rights issued under the Company’s 1993 Incentive Stock Option, Non Qualified Stock Option and Restricted Stock Purchase Plan, 1996 Stock Incentive Plan, Employee Stock Purchase Plan or any other similar plan, arrangement, agreement or understanding.

(n) Tax Matters

There are no federal, state, county or local taxes due and payable by the Company or any of its Subsidiaries which have not been paid. The provisions for taxes on the audited and unaudited balance sheets described in Section 3.7 are sufficient for the payment of all accrued and unpaid federal, state, county and local taxes of the Company whether or not assessed or disputed as of the respective dates of such balance sheets. The Company and its Subsidiaries have duly filed all federal, state, county and local tax returns required to have been filed by it and there are in effect no waivers of applicable statutes of limitations with respect to taxes for any year. Neither the Company nor any of its Subsidiaries is currently subject to a federal or state tax audit of any kind.

(o) Intellectual Property

The Company owns or possesses the licenses or rights to use all Intellectual Property necessary to enable it to conduct its business as now operated or as currently proposed to be operated. There are no material outstanding options, licenses or agreements relating to the Intellectual Property of the Company or its Subsidiaries. Neither the Company nor any Subsidiary is bound by or a party to any material options, licenses or agreements relating to the Intellectual Property of any other person or entity. There is no claim or action or proceeding pending or, to the Company’s knowledge, threatened that (a) challenges the rights of the Company or its Subsidiaries with respect to any Intellectual Property owned by the Company or its Subsidiaries, or (b) arises out of or related to the Company’s or any Subsidiary’s alleged infringement or alleged misappropriation of any third party’s Intellectual Property.

(p) Title to Tangible Assets

The Company and its Subsidiaries have good title to their properties and assets and good title to all their leasehold estates, in each case subject to no mortgage, pledge, lien, lease, encumbrance or charge, other than or resulting from taxes which have not yet become delinquent and minor liens and encumbrances which do not in any case materially detract from the value of the property subject thereto or materially impair the operations of the Company and its Subsidiaries and which have not arisen otherwise than in the ordinary course of business.

(q) Insurance

The Company and its Subsidiaries and their respective properties are insured in such amounts, against such losses and with such insurers as are prudent when considered in light of the nature of the properties and businesses of the Company and its Subsidiaries. No notice of any termination or threatened termination of any of such policies has been received and such policies are in full force and effect.

(r) Transactions with Related Parties

Neither the Company nor any Subsidiary is a party to any agreement with any of the Company’s directors, officers or stockholders or any Affiliate or family member of any of the foregoing under which it: (i) leases any real or personal property (either to or from such Person); (ii) licenses technology (either to or from such Person); (iii) is obligated to purchase any tangible or intangible asset from or sell such asset to such Person; (iv) purchases products or services from such Person; or (v) has borrowed money from or lent money to such Person.

Except for any interest held directly or indirectly by those officers and directors set forth in the Company SEC Reports or interests held by Affiliates of Micro Investment, neither the Company nor any of its officers or, to the best of its knowledge, directors, has any interest, either by way of contract or by way of investment (other than as holder of not more than 2% of the outstanding capital stock of a publicly traded Person) or otherwise, directly or indirectly, in any Person other than the Company that (i) provides any services or designs, produces or sells any product or product lines or engages in any activity similar to or competitive with any activity currently proposed to be conducted by the Company or any of its Subsidiaries or (ii) has any direct or indirect interest in any asset or property, real or personal, tangible or intangible, of the Company or its Subsidiaries.

(t) Registration Rights

Except as provided pursuant to Section 5.10, the Company will not, as of the First Closing Date or the Second Closing Date, be under any obligation to register any of its securities under the Securities Act.

(i) Each Investor covenants that it will not sell or otherwise transfer the Exchangeable Notes or the Second Closing Shares except pursuant to an effective registration under the Securities Act or in a transaction which, in the opinion of counsel reasonably satisfactory to the Company, qualifies as an exempt transaction under the Securities Act and the rules and regulations promulgated thereunder; provided, however, without any obligation to deliver an opinion of counsel, each Investor shall be able to transfer the Exchangeable Notes or the Second Closing Shares to Affiliates and to ev3 LLC, a Delaware limited liability company, and its Affiliates.

(b) Covenants Pending Closing

Pending the Closings, the Company will conduct and will cause its Subsidiaries to conduct their respective businesses in the ordinary course, and will not, and will not permit any of its Subsidiaries to, without the Investors’ prior written consent, take any action which would result in any of the representations or warranties contained in this Agreement not being true at and as of the time immediately after such action, or in any of the covenants contained in this Agreement becoming incapable of performance. The Company will promptly advise the Investors of any action or event of which it becomes aware which has the effect of making incorrect any of such representations or warranties or which has the effect of rendering any of such covenants incapable of performance.

Each of the parties shall execute such documents and other papers and take such further actions as may be reasonably required or desirable to carry out the provisions hereof and the transactions contemplated hereby. Each such party shall use its reasonable efforts to fulfill or obtain the fulfillment of the conditions to either Closing as promptly as practicable.

(d) Indemnity

(i) The Company agrees to indemnify and hold each Investor, its members and its Affiliates and each of their respective officers, directors, partners, members, employees and agents, and each person who controls the Investor or any of its members (within the meaning of the Exchange Act) (the “Indemnified Parties”) harmless against any and all losses, liabilities, damages, expenses and other costs (“Losses”) arising from any actual or threatened claims brought against the Company or such Indemnified Parties in connection with or arising out of entering into this Agreement and the transactions contemplated hereby or any other legal, administrative or other proceeding arising out of the transactions contemplated hereby, other than such Losses which are judicially determined to have resulted from (i) the gross negligence or willful misconduct of the Investor or such other Indemnified Party or (ii) the breach by the Investor of any of the terms of this Agreement.

(ii) Each Indemnified Party under this Section 5.4 will, promptly after the receipt of notice of the commencement of any action against such Indemnified Party in respect of which indemnity may be sought from the Company on account of an indemnity agreement contained in this Section 5.4, notify the Company in writing of the commencement thereof. The omission of any Indemnified Party so to notify the Company of any such action shall not relieve the Company from any liability which it may have to such Indemnified Party other than pursuant to this Section 5.4 or, unless the Company shall have been prejudiced by the omission of such Indemnified Party so to notify the Company, pursuant to this Section 5.4. In case any such action shall be brought against any Indemnified Party and it shall notify the Company of the commencement thereof, the Company shall be entitled to participate therein and, to the extent that it may wish, to assume the defense thereof, with counsel reasonably satisfactory to such Indemnified Party, and after notice from the Company to such Indemnified Party of its election so to assume the defense thereof, the Company will not be liable to such Indemnified Party under this Section 5.4 for any legal or other expense subsequently incurred by such Indemnified Party in connection with the defense thereof; provided, however, that (1) if the Company shall elect not to assume the defense of such claim or action or (2) if the Indemnified Party reasonably determines (A) that there may be a conflict between the positions of the Company and of the Indemnified Party in defending such claim or action or (B) that there may be legal defenses available to such Indemnified Party different from or in addition to those available to the Company, then separate counsel for the Indemnified Party shall be entitled to participate in and conduct the defense, in the case of (1) and (2)(A), or such different defenses, in the case of (2)(B), and the Company shall be liable for any reasonable legal or other expenses incurred by the Indemnified Party in connection with the defense.

(e) Exchange of Exchangeable Notes for Common Stock

(i) Upon the receipt of the Stockholder Approval and the satisfaction of the other conditions to the Second Closing, all of the outstanding principal and accrued but unpaid interest on the Investors’ Exchangeable Notes shall be exchanged for such number of shares of Common Stock as shall be equal to the quotient obtained by dividing (i) the aggregate outstanding principal balance plus any accrued but unpaid interest then outstanding on such Investor’s Exchangeable Notes by (ii) $2.73 (subject to appropriate adjustment in the event of

any stock dividend, stock split, stock distribution or combination, subdivision, reclassification or other corporate actions having the similar effect with respect to the Common Stock, the “Exchange Price”); provided, however, the Investors shall have no obligation to exchange the Exchangeable Notes for Common Stock if the conditions precedent to the Second Closing set forth in Section 6 have not been satisfied on or prior to the date that is ninety (90) days following the date of the First Closing Date (the “Exchange Termination Date”), including, without limitation, if on or before the Exchange Termination Date, there shall have occurred any developments in the business of the Company or any of its Subsidiaries which, individually or in the aggregate, has had, or would be reasonably likely to have, a Material Adverse Effect. If Stockholder Approval at the Special Meeting (as defined herein) is not obtained, then the Investors shall not have the option to, and the Company shall not be required to, exchange all or any portion of the outstanding principal and accrued but unpaid interest then outstanding on the Exchangeable Notes for shares of Common Stock and such Exchangeable Notes shall remain outstanding pursuant to their terms.

(ii) If the Second Closing has not occurred by the Exchange Termination Date, each Investor shall have the right, but not the obligation, at anytime following such date and from time to time, upon receipt of the Stockholder Approval, to exchange all or any portion of the outstanding principal and accrued but unpaid interest on such Investor’s Exchangeable Notes for such number of shares of Common Stock as shall be equal to the quotient obtained by dividing (i) the aggregate outstanding principal balance plus any accrued but unpaid interest then outstanding on such Investor’s Exchangeable Notes by (ii) the Exchange Price. If an Investor elects to exchange all or any portion of the outstanding principal balance and accrued but unpaid interest on such Investor’s Exchangeable Note, the Investor shall give notice to the Company of the principal amount of the Exchangeable Note and/or accrued but unpaid interest thereon to be exchanged and the name(s) in which the certificate(s) for the shares of Common Stock are to be issued. If at the time of exchange of the Exchangeable Notes for shares of Common Stock there are insufficient authorized shares of Common Stock to permit exchange in full of the Exchangeable Notes proposed to be so exchanged, then the Company shall take all corporate action necessary to authorize a sufficient number of shares of Common Stock to permit such exchange in full. Upon any partial exchange by an Investor pursuant to which only a portion of the outstanding principal balance and unpaid accrued interest of an Exchangeable Note (a “Partial Exchange”), the Company shall issue to such Investor a new Exchangeable Note (dated as of the date of the Exchangeable Note that was exchanged) representing the aggregate amount of the outstanding principal balance and unpaid accrued interest of the Exchangeable Note that was not exchanged in connection with the Partial Exchange, which note shall be in the same form and containing the same terms as the Exchangeable Note that was exchanged in the Partial Exchange.

(iii) No fractional shares of the Common Stock will be issued upon exchange of the Exchangeable Notes for shares of Common Stock. In lieu of any fractional share to which the Investor would otherwise be entitled, the Company will pay to the Investors in cash the amount of the unexchanged principal balance plus accrued but unpaid interest then outstanding on the Exchangeable Notes that would otherwise be exchanged for such fractional share. Upon exchange of the Exchangeable Notes, the Investors shall surrender the Exchangeable Notes, duly endorsed, at the principal offices of the Company or any transfer agent

of the Company. At its expense, the Company will, as soon as practicable thereafter, issue and deliver to such Investors, at such principal office, a certificate or certificates for the number of shares to which each such Investor is entitled upon such exchange, including a check payable to such Investor for any cash amounts payable as described herein. Upon exchange of the Exchangeable Notes and payment for fractional shares as provided above, the Company will be forever released from all of its payment obligations and liabilities under the Exchangeable Notes with regard to that portion of the principal and accrued but unpaid interest being exchanged.

(f) Consents and Approvals; HSR Act; Proxy

(i) From and after the date hereof, the Company shall use its best efforts to obtain as promptly as practicable any consent or approval of any Person, including any regulatory authority, required in connection with the transactions contemplated hereby, including without limitation, the approval by the required vote of the Company’s stockholders to (i) the amendment to the Company’s Certificate of Incorporation to increase the authorized capital stock of the Company to 75,000,000 shares, consisting of 70,000,000 shares of Common Stock and 5,000,000 shares of Preferred Stock (the “Amendment”), (ii) the issuance of the Second Closing Shares upon exchange of the Exchangeable Notes and (iii) such other matters as may be necessary or advisable to consummate the transactions contemplated by this Agreement (such approval by the Company’s stockholders of the matters referred to in (i), (ii) and (iii) is referred to herein as the “Stockholder Approval”).

Any Proxy Statement filed under this Section 5.6(c) shall, to the extent required, contain the recommendation of the Board that the Company’s stockholders approve the transactions contemplated by this Agreement. Each Investor will be given a reasonable opportunity to review and comment on drafts of the Proxy Statement and the Company will use its reasonable best efforts to accept comments thereto given by each Investor and its representatives. The Company shall promptly take all action necessary in accordance with applicable law and its Organizational Documents to convene a special meeting of the Company’s stockholders (the “Special Meeting”) no later than the date that is sixty (60) days following the First Closing Date or, if such date is impracticable due to review by the SEC, as soon as practicable thereafter.

The Company will use its reasonable best efforts to cause the Registration Statement to become effective within sixty (60) days of filing. The expenses of the preparation and filing of the Registration Statement shall be borne by the Company.

(v) file documents required of the Company for normal blue sky clearance in states reasonably specified in writing by any Investor prior to the effectiveness of the Registration Statement, provided, however, that the Company shall not be required to qualify to do business or consent to service of process in any jurisdiction in which it is not now so qualified or has not so consented;

(vi) bear all expenses (other than underwriting discounts and commissions, if any) in connection with the procedures in paragraph (i) through (v) of this Section 1 and the registration of the Second Closing Shares pursuant to the Registration Statement, including without limitation (a) registration and filing fees with the SEC, (b) fees and expenses of compliance with securities or blue sky laws (including reasonable fees and disbursements of Company counsel in connection with blue sky qualifications of the Second Closing Shares), (c) printing expenses, (d) fees and expenses incurred in connection with the listing of the Second Closing Shares, (e) fees and expenses of counsel and independent certified public accountants for the Company (including the expenses of any comfort letters), (f) the fees and expenses of any additional experts retained by the Company in connection with such registration, (g) fees and expenses in connection with any review of underwriting arrangements by the NASD Inc., including fees and expenses of any “qualified independent underwriter,” (h) internal Company expenses (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties), and (i) all reasonable fees and disbursements of one counsel for the Investors in connection with such registration; and

(d) Notwithstanding anything to the contrary herein, the Registration Statement shall cover only the Second Closing Shares. In no event at any time before the Registration Statement becomes effective with respect to the Second Closing Shares shall the Company publicly announce or file any other registration statement, other than a registration statement on Form S-8 relating solely to employee benefit plans, without the prior written consent of each of the Investors.

(e) The Company understands that each of the Investors disclaims being an underwriter, but any Investor being deemed an underwriter by the SEC shall not relieve the Company of any obligations it has hereunder.

Transfer of Second Closing Shares After Registration; Suspension.

(a) Each Investor agrees that it will not effect any disposition of the Second Closing Shares or its right to purchase the Second Closing Shares that would constitute a sale within the meaning of the Securities Act other than transactions exempt from the registration requirements of the Securities Act, except as contemplated in the Registration Statement referred to in Section 1 and as described below or as otherwise permitted by law, and that it will promptly notify the Company of any changes in the information set forth in the Registration Statement regarding itself or its plan of distribution.

(b) Except in the event that paragraph (c) below applies, the Company shall: (i) if deemed necessary by the Company, prepare and file from time to time with the SEC a post-effective amendment to the Registration Statement or a supplement to the related Prospectus or a supplement or amendment to any document incorporated therein by reference or file any other required document so that such Registration Statement will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading, and so that, as thereafter delivered to purchasers of the Second Closing Shares being sold thereunder, such Prospectus will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading; (ii) provide the Investors copies of any documents filed pursuant to Section 2(b)(i); and (iii) upon request, inform any Investor that the Company has complied with its obligations in Section 2(b)(i) (or that, if the Company has filed a post-effective amendment to the Registration Statement which has not yet been declared effective, the Company will notify such Investor to that effect, will use its reasonable efforts to secure the effectiveness of such post-effective amendment as promptly as possible and will promptly notify such Investor pursuant to Section 2(b)(i) hereof when the amendment has become effective).

(c) Subject to paragraph (d) below, in the event: (i) of any request by the SEC or any other federal or state governmental authority during the period of effectiveness of the Registration Statement for amendments or supplements to a Registration Statement or related Prospectus or for additional information; (ii) of the issuance by the SEC or any other federal or state governmental authority of any stop order suspending the effectiveness of a Registration Statement or the initiation of any proceedings for that purpose; (iii) of the receipt by the Company of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Second Closing Shares for sale in any jurisdiction or the initiation of any proceeding for such purpose; or (iv) of any event or circumstance which necessitates the making of any changes in the Registration Statement or Prospectus, or any document incorporated or deemed to be incorporated therein by reference, so that, in the case of the Registration Statement, it will not contain any untrue statement of a material fact or any omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, and that in the case of the Prospectus, it will not contain any untrue statement of a material fact or any omission to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; then the Company shall promptly deliver a certificate in writing to each Investor (the “Suspension Notice”) to the effect of the foregoing and, upon receipt of such Suspension Notice, each Investor will refrain from selling any Second Closing Shares pursuant to the Registration Statement (a “Suspension”) until the Investor’s receipt of copies of a supplemented or amended Prospectus prepared and filed by the Company, or until it is advised in writing by the Company that the current Prospectus may be used, and has received copies of any additional or supplemental filings that are incorporated or deemed incorporated by reference in any such Prospectus. In the event of any Suspension, the Company will use its reasonable efforts to cause the use of the Prospectus so suspended to be resumed as soon as reasonably practicable within 30 days after delivery of a Suspension Notice to the Investors. In addition to and without limiting any other remedies (including, without limitation, at law or at equity) available to the Investors, the Investors shall be entitled to specific performance in the event that the Company fails to comply with the provisions of this Section 2(c).

(d) Notwithstanding the foregoing paragraphs of this Section 2, the Company shall not suspend the Registration Statement which causes any Investor to be prohibited from selling Second Closing Shares under the Registration Statement as a result of such Suspension on more than two occasions of not more than 30 days each in any twelve month period, and any such Suspension must be separated by a period of at least thirty (30) days from a prior Suspension.

(e) Provided that a Suspension is not then in effect each Investor may sell Second Closing Shares under the Registration Statement, provided that it arranges for delivery of a current Prospectus to the transferee of such Second Closing Shares. Upon receipt of a request therefor, the Company will provide the requested number of current Prospectuses to each Investor and to any other parties requiring such Prospectuses.

Indemnification.

For purposes of this Section 3:

the term “Selling Stockholders” means the Investors, their respective partners, officers and members, and each person, if any, who controls an Investor within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act;

the term “Registration Statement” means the Registration Statement, any Preliminary Prospectus, the final Prospectus, any exhibit, supplement or amendment thereto or included in or relating to, and any document incorporated by reference in, the Registration Statement (or deemed to be a part thereof) referred to in Section 1; and

the term “untrue statement” means any untrue statement or alleged untrue statement or any omission or alleged omission to state in the Registration Statement a material fact required to be stated therein or necessary to make the statements therein not misleading.

(a) The Company agrees to indemnify and hold harmless each Selling Stockholder from and against any losses, claims, damages or liabilities (or actions or proceedings in respect thereof) to which such Selling Stockholder may become subject (under the Securities Act or otherwise) insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of, or are based upon (i) any untrue statement of a material fact contained in the Registration Statement, (ii) any inaccuracy in the representations and warranties of the Company contained in the Agreement or the failure of the Company to perform its obligations thereunder or (iii) any failure by the Company to fulfill any undertaking included in the Registration Statement, and the Company will reimburse such Selling Stockholder for any legal or other expenses reasonably incurred in investigating, defending or preparing to defend any such action, proceeding or claim, provided, however, that the Company shall not be liable in any such case to the extent that such loss, claim, damage or liability arises out of, or is based upon, an untrue statement made in such Registration Statement in reliance upon and in conformity with written information furnished to the Company by or on behalf of such Selling Stockholder and stated to be specifically for use in preparation of the Registration Statement.

(b) Each Investor agrees to indemnify and hold harmless the Company (and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act, each officer of the Company who signs the Registration Statement and each director of the Company) from and against any losses, claims, damages or liabilities to which the Company (or any such officer, director or controlling person) may become subject (under the Securities Act or otherwise), insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of, or are based upon, any untrue statement of a material fact contained in the Registration Statement if such untrue statement was made in reliance upon and in conformity with written information furnished by or on behalf of such Investor and stated to be specifically for use in preparation of the Registration Statement, and such Investor will reimburse the Company (or such officer, director or controlling person), as the case may be, for any legal or other expenses reasonably incurred in investigating, defending or preparing to defend any such action, proceeding or claim. The obligation of such Investor to indemnify shall be limited to the net amount of the proceeds received by such Investor from the sale of the Second Closing Shares pursuant to the Registration Statement.

(c) Each party entitled to indemnification under this Section 3 (the “Indemnified Party”) shall give notice to the party required to provide indemnification (the “Indemnifying Party”) promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party to assume the defense of any such claim or any litigation resulting therefrom; provided that counsel for the Indemnifying Party, who shall conduct the defense of such claim or any litigation resulting therefrom, shall be approved by the Indemnified Party (whose approval shall not unreasonably be withheld) and the Indemnified Party may participate in such defense at such party’s expense (unless the Indemnified Party shall have reasonably concluded, after consultation with counsel, that there may be a conflict of interest between the Indemnifying Party and the Indemnified Party in such action, in which case the reasonable fees and expenses of counsel for the Indemnified Party shall be at the expense of the Indemnifying Party), and provided further that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Section 3, except to the extent that the Indemnifying Party is materially prejudiced thereby. No Indemnifying Party, in the defense of any such claim or litigation shall, except with the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation. Each Indemnified Party shall furnish such information regarding itself or the claim in question as an Indemnifying Party may reasonably request in writing and as shall be reasonably required in connection with the defense of such claim and litigation resulting therefrom.

(d) If the indemnification provided for in this Section 3 is insufficient to or is held by a court of competent jurisdiction to be unavailable to hold harmless an Indemnified Party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to therein, then each Indemnifying Party shall contribute to the amount paid or payable by such Indemnified Party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative fault of the Company on the one hand and such Investor on the other in connection with the statements or omissions or other matters which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative fault shall be determined by reference to, among other things, in the case of an untrue statement, whether the untrue statement relates to information supplied by the Company on the one hand or such Investor on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement. The Company and the Investors agree that it would not be just and equitable if contribution pursuant to this subsection (d) were determined by pro rata allocation or by any other method of allocation which does not take into account the equitable considerations referred to above in this subsection (d). The amount paid or payable by an Indemnified Party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (d), no Investor shall be required to contribute any amount in excess of the amount by which the gross amount received by such Investor from the sale of the Second Closing Shares to which such loss relates exceeds the amount of any

damages which such Investor has otherwise been required to pay by reason of such untrue statement. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Investors obligations in this subsection to contribute are several in proportion to their sales of Second Closing Shares to which such loss relates and not joint.

(e) The indemnity and contribution agreements contained in this Section 3 shall remain operative and in full force and effect regardless of (a) termination of any provision of the Agreement or any underwriting agreement, (b) any investigation made by or on behalf of any Indemnified Person or by or on behalf of the Company and (c) the consummation of the sale or successive resales of the Second Closing Shares.

Liquidated Damages Under Certain Circumstances.

(a) If (i) the Registration Statement has not been declared effective by the SEC by (w) the date that is 60 days after the date of the Second Closing, or (x) if the Second Closing shall not have occurred by the Exchange Termination Date, the date that is 60 days after the first date on which an Investor exchanges all or any portion of such Investor’s Exchangeable Note pursuant to Section 5.5(b) of the Agreement, or (ii) the Registration Statement is filed and declared effective but shall thereafter be subject to a Suspension which shall be in effect for more than 60 days (consecutive or non-consecutive) in the aggregate in any 12-month period, except in cases where (y) such Suspension results from any untrue statement made in the Registration Statement in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Investor specifically for use in preparation of the Registration Statement or (z) in the opinion of counsel to the Company, during the entire duration of the Suspension, the Investors may sell all Second Closing Shares then held by the Investors in any 90-day period pursuant to Rule 144 under the Securities Act (without restriction by the volume limitation of Rule 144(e)) (each such event referred to in clauses (i) and (ii), a “Registration Default”), the Company will pay liquidated damages to the Investors (in proportion to the number of Second Closing Shares then held by each Investor) in an amount equal to two percent (2%) of the aggregate principal amount of the Exchangeable Notes issued to the Investors on the First Closing Date, which amount shall be paid to the Investors (a) within 10 days following the date of the Registration Default, and (b) in the event the Registration Default continues, upon every 30-day period the Registration Default continues, which 30-day periods shall be measured from the date of the Registration Default. For the purpose of subsection (b) above, the payment of such liquidated damages shall be made within 10 days following the date that is the end of the then applicable 30-day period. Such liquidated damages will be payable to each Investor on demand by wire transfer of immediately available funds or by federal funds check by the Company.

(b) Nothing herein limits each Investor’s right to pursue actual damages for the Company’s failure to ensure sales can be made under the Registration Statement or the Company’s failure to ensure the Common Stock is listed or included for quotation, as the case may be, on an Approved Market.

5. Information Available. So long as the Registration Statement is effective covering the resale of Second Closing Shares owned by any Investor, the Company will furnish to each such Investor:

(a) as soon as it is delivered to the Company’s other stockholders, one copy of (i) its Annual Report to Stockholders (which Annual Report shall contain financial statements prepared in accordance with generally accepted accounting principles in the United States of America by the Company) and (ii) if not included in substance in the Annual Report to Stockholders, its Annual Report on Form 10-KSB (the foregoing, in each case, excluding exhibits);

(b) upon the reasonable request of such Investor, all exhibits excluded by the parenthetical to subparagraph (a)(ii) of this Section 5 as filed with the SEC and all other information that is made available to stockholders; and

(c) upon the reasonable request of such Investor, an adequate number of copies of the Prospectuses to supply to any other party requiring such Prospectuses; and the Company, upon the reasonable request of such Investor, will meet with such Investor or a representative thereof at the Company’s headquarters to discuss all information relevant for disclosure in the Registration Statement covering the Second Closing Shares and will otherwise cooperate with such Investor in conducting an investigation for the purpose of reducing or eliminating such Investor’s exposure to liability under the Securities Act, including the reasonable production of information at the Company’s headquarters; provided, that the Company shall not be required to disclose any confidential information to or meet at its headquarters with such Investor until and unless such Investor shall have entered into a confidentiality agreement in form and substance reasonably satisfactory to the Company with the Company with respect thereto.

6. Public Statements. The Company will not issue any public statement, press release or any other public disclosure concerning the Purchase Agreement and the transactions contemplated thereby without the prior written consent of the Investors, which consent shall not be unreasonably withheld, except as may be required by applicable law or rules of any exchange on which the Company’s securities are listed.
