Each of the Issuer and its Subsidiaries is duly qualified to do business and is in good standing in each jurisdiction in which the nature of its business requires qualification or good standing, except for any failure to be so qualified or be in good standing that would not have a Material Adverse Effect.

3.3 Enforceability. This Agreement has been duly executed and delivered by the Issuer and (assuming it has been duly authorized, executed and delivered by the Investor) constitutes a legal, valid and binding obligation of the Issuer, enforceable against the Issuer in accordance with its terms, except (a) as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the enforcement of creditors’ rights generally, and (b) the indemnity provisions of Section 7 of this Agreement, which may not be enforceable based upon public policy considerations, and general equitable principles, regardless of whether such enforceability is considered in a proceeding at law or in equity.

The execution and delivery by the Issuer of this Agreement, the consummation of the transactions contemplated hereby, and the compliance by the Issuer with the terms and provisions hereof (including, without limitation, the Issuer’s issuance to the Investor of the Shares as contemplated by and in accordance with this Agreement), will not result in a default under (or give any other party the right, with the giving of notice or the passage of time (or both), to declare a default or accelerate any obligation under) or violate the Certificate of Incorporation or By-Laws of the Issuer or any material Contract to which the Issuer is a party (except to the extent such a default, acceleration, or violation would not, in the case of a Contract, have a Material Adverse Effect on the Issuer), or materially violate any Requirement of Law applicable to the Issuer, or result in the creation or imposition of any material Lien upon any of the capital stock, properties or assets of the Issuer or any of its Subsidiaries (except where such violations of any Requirement of Law or creations or impositions of any Liens would not have a Material Adverse Effect on the Issuer). Neither the Issuer nor any of its Subsidiaries is (a) in default under or in violation of any material Contract to which it is a party or by which it or any of its properties

To the Issuer’s knowledge, neither the Issuer nor any of its Subsidiaries is in default under, or in violation of or noncompliance with, any of such Permits, except for any such default, violation, or noncompliance which would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. To the Issuer’s knowledge, other than as disclosed in the SEC Reports, there is no proposed change in any Requirements of Law which would require the Issuer and its Subsidiaries to obtain any Permits in order to conduct its business as presently conducted that the

Issuer and its Subsidiaries do not currently possess and the lack of which could reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect.

To the Issuer’s knowledge, the Issuer is not infringing on any intellectual property rights of any other person, nor is there any claim of infringement made or threatened by a third party against or involving the Issuer.

Except as disclosed in the SEC Reports, each such material Contract is in full force and effect, except as otherwise required pursuant to its respective terms, and is binding on the Issuer or its Subsidiaries, as the case may be, in each case, in accordance with its respective terms, and neither the Issuer or any of its Subsidiaries nor, to the Issuer’s knowledge, any other party thereto is in breach of, or in default under, any such material Contract, which breach or default would reasonably be expected to have a Material Adverse Effect. Except as set forth in the SEC Reports, there exists no actual or, to the knowledge of the Issuer, threatened termination, cancellation or limitation of, or any material adverse modification or change in, the business relationship of the Issuer or any of its Subsidiaries, or the business of the Issuer or any of its Subsidiaries, with any customer or supplier or any group of customers or suppliers whose purchases or inventories provided to the business of the Issuer or any of its Subsidiaries would, individually or in the aggregate, have a Material Adverse Effect.

The Issuer shall thereafter maintain the effectiveness of the Registration Statement until the earlier of (a) the date on which all the Registrable Securities have been sold pursuant to the Registration Statement or Rule 144 promulgated under the Securities Act (“Rule 144”), (b) such time as the Issuer reasonably determines, based on an opinion of counsel, that all of the Holders will be eligible to sell under Rule 144 all of the Securities then owned by the Holders within the volume limitations imposed by paragraph (e) of Rule 144 in the three month period immediately following the termination of the effectiveness of the Registration Statement, and (c) the first anniversary of the date the Registration Statement was declared effective by the SEC. The Registration Statement filed pursuant to this Section 6.2 may include other securities of the Issuer that are held by Persons who, by virtue of agreements with the Issuer, are entitled to similar registration rights.

6.3 Registration Procedures.

(a) In case of the Registration Statement effected by the Issuer subject to this Section 6, the Issuer shall keep the Investor, on behalf of Holder, advised in writing as to the initiation of such registration, and as to the completion thereof. In addition, subject to Section 6.2 above, the Issuer shall, to the extent applicable to the Registration Statement:

(i) prepare and file with the SEC such amendments and supplements to the Registration Statement as may be necessary to keep such registration continuously effective and free from any material misstatement or omission necessary to make the statements therein, in light of the circumstances, not misleading, and comply with provisions of the Securities Act with respect to the disposition of all securities covered thereby during the period referred to in Section 6.2;

(ii) update, correct, amend and supplement the Registration Statement as necessary;

(iii) notify the Holder promptly when the Registration Statement is declared effective by the SEC, and furnish such number of prospectuses, including preliminary prospectuses, and other documents incident thereto as Holder may reasonably request from time to time;

(iv) use its commercially reasonable efforts to register or qualify such Registrable Securities under such other securities or blue sky laws of such jurisdictions of the United States where an exemption is not available and as Holder may reasonably request to enable it to consummate the disposition in such jurisdiction of the Registrable Securities (provided that the Issuer will not be required to (A) qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this provision, or (B) consent to general service of process in any such jurisdiction, or (C) subject itself to taxation in any jurisdiction where it is not already subject to taxation);

(v) notify Holder at any time when a prospectus relating to the Registrable Securities is required to be delivered under the Securities Act, of the happening of any event as a result of which the prospectus included in the Registration Statement contains an untrue statement of a material fact or omits any fact necessary to make the statements therein not misleading and, subject to Section 6.6, the Issuer will prepare a supplement or amendment to such prospectus, so that, as thereafter delivered to purchasers of such shares, such prospectus will not contain any untrue statements of a material fact or omit to state any fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading;

(vi) cause all such Registrable Securities to be listed on each securities exchange on which similar securities issued by the Issuer are then listed and obtain all necessary approvals for trading thereon;

(vii) provide a transfer agent and registrar for all such Registrable Securities not later than the effective date of the Registration Statement;

(viii) upon the sale of any Registrable Securities pursuant to the Registration Statement, direct the transfer agent to remove all restrictive legends from all certificates or other instruments evidencing the Registrable Securities;

(ix) With a view to making available to the Holder the benefits of certain rules and regulations of the SEC that at any time permit the sale of the Registrable Securities to the public without registration, so long as any Registrable Securities are outstanding, the Issuer shall use its commercially reasonable efforts for a period of two years following the date of Closing:

(1) to make and keep public information available, as those terms are understood and defined in Rule 144(c) under the Securities Act;

(2) to file with the SEC in a timely manner all reports and other documents required of the Issuer under the Exchange Act; and

(3) to furnish to the Holder upon any reasonable request a written statement by the Issuer as to its compliance with the public information requirements of Rule 144(c) under the Securities Act; and

(x) To advise the Holder promptly after it has received notice or obtained knowledge of the existence of any stop order by the SEC delaying or suspending the effectiveness of the Registration Statement or of the initiation or threat of any proceeding for that purpose, and to make every commercially reasonable effort to obtain the withdrawal of any order suspending the effectiveness of the Registration Statement at the earliest possible time.

(b) Notwithstanding anything stated or implied to the contrary in Section 6.3(a) above, the Issuer shall not be required to consent to any underwritten offering of the Registrable Securities or to any specific underwriter participating in any underwritten public offering of the Registrable Securities.

(c) Each Holder agrees that upon receipt of any notice from the Issuer of the happening of any event of the kind described in Section 6.3(a)(v), and subject to Section 6.5, such Holder will forthwith discontinue such Holder’s disposition of Registrable Securities pursuant to the registration statement relating to such Registrable Securities until such Holder’s receipt of the copies of the supplemented or amended prospectus contemplated by Section 6.3(a)(v) and, if so directed by the Issuer, will deliver to the Issuer at the Issuer’s expense all

copies, other than permanent file copies, then in such Holder’s possession, of the prospectus relating to such Registrable Securities current at the time of receipt of such notice.

(d) Except as required by law, all expenses incurred by the Issuer in complying with this Section 6, including but not limited to, all registration, qualification and filing fees, printing expenses, fees and disbursements of counsel and accountants for the Issuer, blue sky fees and expenses (including fees and disbursements of counsel related to all blue sky matters) incurred in connection with any registration, qualification or compliance pursuant to this Section 6 shall be borne by the Issuer. All underwriting discounts and selling commissions applicable to a sale incurred in connection with any registration of Registrable Securities and the legal fees and other expenses of a Holder shall be borne by such Holder.

6.4 Further Information. If Registrable Securities owned by a Holder are included in any registration, such Holder shall furnish the Issuer such information regarding itself as the Issuer may reasonably request and as shall be required in connection with any registration (or amendment or supplement thereto), referred to in this Agreement, and Holder shall indemnify the Issuer with respect thereto in accordance with Section 7 hereof. The Investor hereby represents and warrants to the Issuer that it has accurately and completely provided the requested information and answered the questions numbered (a) through (d) on the signature pages of this Agreement, and the Investor agrees and acknowledges that the Issuer may rely on such information as being true and correct for purposes of preparing and filing the Registration Statement at the time of filing thereof and at the time it is declared effective, unless the Investor has notified the Issuer in writing to the contrary prior to such time.

6.5 Right of Suspension.

(a) Notwithstanding any other provision of this Agreement or any related agreement to the contrary, the Issuer shall have the right, at any time, to suspend the effectiveness of the Registration Statement and offers and sales of the Registrable Securities pursuant thereto whenever, in the good faith judgment of the Issuer, (i) continuing such effectiveness or permitting such offers and sales could reasonably be expected to have an adverse effect upon the Issuer’s ability to raise additional funds pursuant to one or more private placements of shares of the Issuer or any debt securities of the Issuer, a proposed sale of all or substantially all of the assets of the Issuer or a merger, acquisition, reorganization, recapitalization or similar current transaction materially affecting the capital, structure, or equity ownership of the Issuer, (ii) the Registration Statement must be suspended in order to register additional shares of Preferred Stock or Common Stock, (iii) there exists a material development or a potential material development with respect to or involving the Issuer that the Issuer would be obligated to disclose in the prospectus used in connection with the Registration Statement, which disclosure, in the good faith judgment of the Issuer, after considering the advice of counsel, would be premature or otherwise inadvisable at such time, or (iv) the Registration Statement or related prospectus or any document incorporated or deemed to be incorporated therein by reference contains an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein, in light of the

circumstances, not misleading, including without limitation that period annually during which any Registration Statement would require suspension pending the Issuer’s new fiscal year financial statements (each, a “Suspension Event”). In the event that the Issuer shall determine to so suspend the effectiveness of the Registration Statement and offers and sales of the Registrable Securities pursuant thereto, the Issuer shall, in addition to performing those acts required to be performed under the Securities Act and/or the Exchange Act or deemed advisable by the Issuer, deliver to each Holder written notice thereof, signed by the Chief Financial Officer or Chief Executive Officer of the Issuer. Upon receipt of such notice, the Holders shall discontinue disposition of the Registrable Securities pursuant to the Registration Statement and prospectus until such Holders (x) are advised in writing by the Issuer that the use of the Registration Statement and prospectus (and offers and sales thereunder) may be resumed, (y) have received copies of a supplemental or amended prospectus, if applicable, and (z) have received copies of any additional or supplemental filings which are incorporated or deemed to be incorporated by reference into such prospectus. The Issuer will exercise commercially reasonable efforts to ensure that the use of the Registration Statement and prospectus may be resumed as quickly as practicable.

(b) The Issuer’s right to suspend the effectiveness of the Registration Statement and the offers and sales of the Registrable Securities pursuant thereto, as described above in this Section 6.5(a), shall be for a period of time (the “Suspension Period”) beginning on the date of the occurrence of the Suspension Event and expiring on the earlier to occur of (i) the date on which the Suspension Event ceases, or (ii) ninety (90) days after the occurrence of the Suspension Event; provided, however, that there shall not be more than two Suspension Periods in any 12-month period. Notwithstanding the foregoing, the Issuer shall be able to suspend the effectiveness of the Registration Statement and offers and sales of the Registrable Securities for any time period as may reasonably be required in order to update the Registration Statement to replace financial information which is no longer current, as required by applicable securities law.

(c) In addition, in connection with any underwritten public offering of securities of the Issuer, if requested by the Issuer or its managing underwriter, each Holder will enter into a lock-up agreement pursuant to which such Holder will not, during the seven (7) days prior to, and for a period no longer than one hundred eighty (180) days following, the date of the prospectus (or if the offering is pursuant to a shelf registration statement, the date of the pricing prospectus supplement) relating to the offering, offer, sell or otherwise dispose of any securities of the Issuer without the prior consent of the Issuer and the managing underwriter, provided that the executive officers and directors of the Issuer enter into lock-up agreements for a period at least as long and on the same terms.

6.6 Transfer of Securities. An Investor may transfer all or any part of its Securities to any Person under common management with the Investor; provided, that any such transfer shall be effected in full compliance with all applicable federal and state securities laws, including, but not limited to, the Securities Act and the rules of the SEC promulgated thereunder. The Issuer will effect such transfer of restricted certificates and will promptly amend or supplement the

Prospectus forming a part of the Registration Statement to add the transferee to the selling stockholders in the Registration Statement; provided that the transferor and transferee shall be required to provide the Issuer with the information requested of the Investor in this Agreement, information reasonably necessary for the Issuer to determine that the transfer was effected in accordance with all applicable federal and state securities laws, including, but not limited to, the Securities Act and the rules of the SEC promulgated thereunder, and all other information reasonably requested by the Issuer from time to time in connection with any transfer, registration, qualification or compliance referred to in Section 6.4.

INDEMNIFICATION.

7.1 Indemnification by the Issuer. The Issuer will indemnify and hold harmless each Holder of Registrable Securities which are included in a registration statement pursuant to the provisions of Section 6 hereof and any underwriter (as defined in the Securities Act) for such Holder, and any person who controls such Holder within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act or such underwriter within the meaning of the Securities Act, and any officer, director, investment adviser, employee, agent, partner, member or affiliate of such Holder (each, a “Holder Indemnified Party”), from and against, and will reimburse each such Holder Indemnified Party with respect to, any and all claims, actions, demands, losses, damages, liabilities, costs and reasonably incurred expenses to which such Holder or any such Holder Indemnified Party may become subject under the Securities Act or otherwise, insofar as such claims, actions, demands, losses, damages, liabilities, costs or reasonably incurred expenses arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in such registration statement, any prospectus contained therein or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or (ii) any materially inaccurate representation or breach of any material warranty, agreement or covenant of the Issuer contained herein; provided, however, that the Issuer will not be liable in any such case to the extent that any such claim, action, demand, loss, damage, liability, cost or expense is caused by an untrue statement or alleged untrue statement or omission or alleged omission (1) made in conformity with information furnished by such Holder in writing specifically for use in the preparation thereof, or (2) which was cured in an amendment or supplement to the prospectus (or any amendment or supplement thereto) delivered to the Holder on a timely basis to permit proper delivery thereof prior to the date on which any Registrable Securities were transferred or sold.

7.2 Indemnification by the Holder. Each Holder of Registrable Securities which are included in a registration statement pursuant to the provisions of Section 6 hereof will indemnify and hold harmless the Issuer, and any Person who controls the Issuer within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and any officer, director, employee, agent, partner, member or affiliate of the Issuer (each, an “Issuer Indemnified Party”) from and against, and will reimburse the Issuer Indemnified Parties with respect to, any and all losses, damages, liabilities, costs or reasonably incurred expenses to which such Issuer Indemnified Parties may become subject under the Securities Act or otherwise, insofar as such

losses, damages, liabilities, costs or reasonably incurred expenses are caused by any untrue or alleged untrue statement of any material fact contained in such registration statement, any prospectus contained therein or any amendment or supplement thereto, or are caused by the omission or the alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was so made solely in reliance upon and in conformity with written information furnished by such Holder specifically for use in the preparation thereof; provided, however, that the liability of any Holder pursuant to this Section 7.2 shall be limited to an amount not to exceed the net proceeds received by such Holder from the sale of Registrable Securities pursuant to the registration statement which gives rise to such obligation to indemnify.

7.3 Procedures. Promptly after receipt by a party indemnified pursuant to the provisions of Section 7.1 or Section 7.2 of notice of the commencement of any action involving the subject matter of the foregoing indemnity provisions, such indemnified party will, if a claim thereof is to be made against the indemnifying party pursuant to the provisions of Section 7.1 or Section 7.2, notify the indemnifying party of the commencement thereof; but the omission to so notify the indemnifying party will not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 7 and shall not relieve the indemnifying party from liability under this Section 7, except to the extent that such indemnifying party is materially prejudiced by such omission. In case such action is brought against any indemnified party and such indemnified party notifies the indemnifying party of the commencement thereof, the indemnifying party shall have the right to participate in, and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of its election to assume the defense thereof, the indemnifying party will not be liable to such indemnified party pursuant to the provisions of Section 7.1 or Section 7.2 for any legal or other expense subsequently incurred by such indemnified party in connection with the defense thereof. No indemnifying party shall be liable to an indemnified party for any settlement of any action or claim without the consent of the indemnifying party. No indemnifying party will 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.

RISK FACTORS RELATED TO THE OFFERING

SALES OR THE PERCEPTION OF FUTURE SALES OF OUR COMMON STOCK MAY DEPRESS OUR STOCK PRICE. BECAUSE THE MARKET PRICES FOR BIOTECHNOLOGY AND MEDICAL DEVICE STOCKS ARE LIKELY TO REMAIN VOLATILE, OUR STOCK PRICE MAY BE MORE ADVERSELY AFFECTED THAN OTHER COMPANIES BY SUCH FUTURE SALES.

Sales of substantial numbers of shares of our Common Stock in the public market, or the perception that significant sales are likely, could adversely affect the market price of our Common Stock. Compliance with the registration rights provisions of the Subscription Agreement could create the perception that all Shares that are a part of this Offering (up to $5 million worth of shares) will soon be available for sale, and this number of shares is greater than the average trading volume for our shares. No prediction can be made as to the effect, if any, that market sales of such shares will have on the market price of our Common Stock. Sales of substantial amounts of such shares in the public market could adversely affect the market price of our Common Stock.

THE OFFERING PRICE OF THE SHARES MAY NOT BEAR ANY RELATIONSHIP TO OUR ASSETS, BOOK VALUE, EARNINGS HISTORY, OR OTHER ESTABLISHED CRITERIA. AS A RESULT, YOU MAY EXPERIENCE IMMEDIATE AND SUBSTANTIAL DILUTION.

The offering price of the Shares was established based on such factors as our capital requirements, financial conditions and prospects, percentage of ownership to be held by investors following this Offering, and the general condition of securities markets at the time of the Offering. The offering price does not necessarily bear any relationship to our assets, book value, earnings history or other established criteria of value. As a result, you may experience immediate and substantial dilution.

WE ARE UNABLE TO DETERMINE WITH CERTAINTY WHEN THE REGISTRATION STATEMENT TO BE FILED WITH THE SEC WILL BE DECLARED EFFECTIVE. CONSEQUENTLY, YOU MAY NOT BE ABLE TO SELL YOUR SHARES FOR A SUBSTANTIAL PERIOD OF TIME.

Although we have undertaken to register the Shares for resale by you, you should be aware that we are unable to determine with certainty when the registration statement to be filed with the SEC will become effective. The SEC may seek to review our registration statement, in which case, the period necessary to achieve effectiveness of the registration statement with the SEC will be affected by our ability to provide the SEC with sufficient disclosures satisfactory to the SEC. The length of the SEC review process is uncertain and may extend to a number of months.

As you are aware, the Shares being sold in this Offering are restricted in nature and may not be publicly resold absent the effectiveness of the registration statement or pursuant to an applicable exemption from registration. Consequently, you may not be able to sell your Shares for a substantial period of time.

WE MAY ALLOCATE THE NET PROCEEDS OF THIS OFFERING IN WAYS WITH WHICH YOU MAY NOT AGREE.

We will have broad discretion in how we apply the net proceeds from this Offering. Because the net proceeds of this Offering are not required to be allocated to any specific investment or transaction, you cannot determine at this time the value or appropriateness of our application of the net proceeds, and you and other shareholders may not agree with our decisions. For example, we may attempt to acquire other businesses or assets using a portion of the net proceeds of this Offering which otherwise could have been used for working capital. There can be no assurance that we will be able to acquire any desirable businesses or assets or that, if acquired, that we will be able to successfully develop or integrate such businesses or assets.

Explanation of “BENEFICIAL OWNERSHIP”

Securities that are subject to a power to vote or dispose are deemed beneficially owned by the person who holds such power, directly or indirectly. This means that the same securities may be deemed beneficially owned by more than one person, if such power is shared. In addition, the beneficial ownership rules provide that shares which may be acquired upon exercise of an option or warrant, or which may be acquired upon the termination of a trust, discretionary account or similar arrangement, which can be effected within a period of 60 days from the date of determination, are deemed to be “beneficially” owned. Furthermore, shares that are subject to rights or powers even though such rights or powers to acquire are not exercisable within the 60-day period may also be deemed to be beneficially owned if the rights or powers were acquired “with the purpose or effect of changing or influencing the control of the issuer or in connection with or as a participant in any transaction having such purpose or effect.”

In determining whether securities are “beneficially owned,” benefits which are substantially equivalent to those of ownership by virtue of any contract, understanding, relationship, agreement or other arrangement should cause the securities to be listed as “beneficially owned.”

Thus, for example, securities held for a person’s benefit in the name of others or in the name of any estate or trust in which such person may be interested should also be listed. Securities held by a person’s spouse, children or other members of such person’s family who are such person’s dependents or who live in such person’s household should be listed as “beneficially owned” unless such person does not enjoy benefits equivalent to those of ownership with respect to such securities.

If a person has a proprietary or beneficial interest in a controlled corporation, partnership, personal holding company, trust or estate which owns of record or beneficially any securities, such person should state the amount of such securities owned by such controlled corporation, partnership, personal holding company, trust or estate in lieu of allocating such person’s proprietary interest, and by note or otherwise, please indicate that. In any case, the name of the controlled corporation, partnership, personal holding company, or estate must be stated.

In all cases the nature of the beneficial ownership should be stated.
