The Initial Registration shall be on Form S-1 or another appropriate form permitting registration of such Registrable Securities for resale by such holders in the manner or manners designated by them (including, without limitation, one or more underwritten offerings).

(iii) The Company shall supplement and amend the Shelf Registration if required by the rules, regulations or instructions applicable to the registration form used by the Company for such Shelf Registration, if required by the Securities Act. (B) DEMAND REGISTRATION.

(ii) If the Investors initiating the registration request under this Section 2(b) ("INITIATING INVESTORS") intend to distribute the Demand Securities covered by their request by means of an Underwritten Offering, then they shall so advise the Company as a part of their request made pursuant to this Section 2(b) and the Company shall include such information in the Request Notice referred to in subsection (i) of this Section 2(b). In such event, the right of any Investor to include his Demand Securities and, if applicable, Holdover Securities in such 4 registration shall be conditioned upon such Investor's participation in such Underwritten Offering and the inclusion of such Investor's Demand Securities in the Underwritten Offering (unless otherwise mutually agreed by a majority in interest of the Initiating Investors and such Investor) to the extent provided herein. All Investors proposing to distribute their securities through such Underwritten Offering shall enter into an underwriting agreement in customary form with the managing underwriter or underwriters selected for such Underwritten Offering by the Company. Notwithstanding any other provision of this Section 2(b), if the underwriter(s) advise(s) the Company in writing that marketing factors require a limitation of the number of securities to be underwritten then the Company shall so advise all Investors owning Demand Securities and, if applicable, Holdover Securities, which would otherwise be registered and underwritten pursuant hereto, and the number of Demand Securities and, if applicable, Holdover Securities, that may be included in the Underwritten Offering shall be reduced as required by the underwriter(s) and allocated among the Investors owning Demand Securities and, if applicable, Holdover Securities, on a pro rata basis according to the number of Demand Securities and, if applicable, Holdover Securities, then outstanding held by each Investor requesting registration (including the Initiating Investors). (iii) MAXIMUM NUMBER OF DEMAND REGISTRATIONS. The Company is obligated to effect only two (2) such registrations pursuant to this Section 2(b) in any calendar year. (iv) DEFERRAL. Notwithstanding the foregoing, if the Company shall furnish to Investors requesting a Demand Registration, a certificate signed by the President or Chief Executive Officer of the Company stating that in the good faith judgment of the Board of Directors of the Company, it would be seriously detrimental to the Company and its shareholders for such registration statement to be filed and it is therefore essential to defer the filing of such registration statement, then the Company shall have the right to defer such filing for a period of not more than one hundred twenty (120) days after receipt of the request of the Initiating Investors; PROVIDED, HOWEVER, that the Company may not utilize this right more than once in any twelve (12) month period. (v) FORM S-3 REGISTRATION. In lieu of the Company's obligation to effect Demand Registrations pursuant to this Section 2(b), the Company may, at its election, at any time after the Effectiveness Period of the Shelf Registration, prepare, file and cause to be effective a Registration Statement on Form S-3, and subject to the provisions of Section 3(a), keep such Registration Statement effective pursuant to Rule 415 until the Registration Termination Date. Upon the effectiveness of such Registration Statement on Form S-3, the Investors shall no longer be permitted to effect a Demand Registration. 3. OBLIGATIONS OF THE COMPANY. In connection with the registration of the Registrable Securities pursuant to this Agreement, the Company shall: 5 (a) prepare promptly and file with the SEC promptly (but in no event later than as is set forth in Section 2 hereof) a Registration Statement with respect to all Registrable Securities to be included therein, and thereafter use its best efforts to cause the Registration Statement to become effective as soon as reasonably possible after such filing, and keep the Registration Statement effective pursuant to Rule 415 (except in the case of an underwritten offering, for which Rule 415 will not be used) at all times during the Effectiveness Period or until the Registration Termination Date, whichever occurs first, which Registration Statement (including any amendments or supplements thereto and prospectuses contained therein) shall not contain any 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 in which they were made, not misleading PROVIDED, HOWEVER, that each Investor shall have complied with its obligations under Section 4 with respect to the Registrable Securities of such Investor to be included in the Registration Statement. Notwithstanding the foregoing, in the event that (i) any request is made by the SEC or any other federal or state governmental authority during the Effectiveness Period for amendments or supplements to a Registration Statement or related prospectus, (ii) any event occurs that makes any statement made in such Registration Statement or related prospectus or any document incorporated or deemed to be incorporated therein by reference untrue in any material respect or which requires the making of any changes in the Registration Statement or prospectus so that, in the case of the Registration Statement, it will not contain any untrue statement of 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 omit to state any 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, (iii) during the Effective Period for the Shelf Registration, the Company becomes eligible to utilize From S-3 (in which case, the Company shall be permitted to terminate the effectiveness of the Initial Registration and file a Registration Statement on Form S-3 and use its best efforts to cause such Registration Statement to become effective within thirty (30) days with respect to the Registrable Securities), or (iv) in the judgment of the Company, it is advisable to suspend use of the prospectus included in such Registration Statement for a discrete period of time due to pending corporate developments (including the pending automatic conversion of the Series A Shares referred to in Section 7.2(a) of Article III of the Company's Articles of Incorporation, as amended, in which case such discrete period shall be one day), public filings with the SEC or similar events, then the Company shall deliver a certificate in writing to the Investors whose Registrable Securities are included in the Registration Statement to the effect of the foregoing and, upon receipt of such certificate, the use of the Registration Statement and prospectus will be deferred or suspended and will not recommence until such Investor's receipt of copies of the supplemented or amended prospectus, or until such Investors are advised in writing by the Company that the prospectus may be used, and until such Investors have received copies of any additional or supplemental filings that are incorporated or deemed incorporated by reference in such prospectus. The Company will use its best efforts to ensure that the use of the Registration Statement and prospectus may be resumed, as soon as practicable and, in the case of a pending development, filing or event referred to in (iv) above, as soon, in the judgment of the Company, as disclosure of the material information relating to such pending development, filing or event would not have a materially adverse effect on the Company's ability to consummate the transaction, if any, to which such development, filing or event relates. Notwithstanding the foregoing or any other provision of this Agreement, the period during which the Company shall be required to maintain the effectiveness of a 6 Registration Statement with respect to a Demand Registration shall be extended by 1 day for each full or partial day during which the use of such Registration Statement or prospectus is deferred or suspended by the Company in accordance with this Section 2(b); (b) prepare and file with the SEC such amendments (including post- effective amendments) and supplements to the Registration Statement and the prospectus used in connection with the Registration Statement as may be necessary to keep the Shelf Registration or Demand Registration effective at all times until the end of the Effectiveness Period or the Registration Termination Date, whichever occurs first, and, during such period, comply with the provisions of the Securities Act with respect to the disposition of all Registrable Securities of the Company covered by the Registration Statement until such time as all of such Registrable Securities have been disposed of in accordance with the intended methods of disposition by the seller or sellers thereof as set forth in the Registration Statement; (c) furnish to each Investor whose Registrable Securities are included in the Registration Statement, such number of copies of a prospectus, including a preliminary prospectus, and all amendments and supplements thereto and such other documents, as such Investor may reasonably request in order to facilitate the disposition of the Registrable Securities owned by such Investor; (d) use reasonable efforts to (i) register and qualify the Registrable Securities covered by the Shelf Registration or Demand Registration under such other securities or blue sky laws of such jurisdictions as the Investors who hold a majority in interest of the Registrable Securities or Demand Securities, as applicable, being offered reasonably request, (ii) prepare and file in those jurisdictions such amendments (including post-effective amendments) and supplements, (iii) take such other actions as may be necessary to maintain such registrations and qualifications in effect at all times until the end of the Effectiveness Period or the Registration Termination Date, whichever occurs first, and (iv) take all other actions reasonably necessary or advisable to qualify the Registrable Securities or Demand Securities, as applicable, for sale in such jurisdictions; PROVIDED, HOWEVER, that the Company shall not be required in connection therewith or as a condition thereto to (I) quality to do business in any jurisdiction where it would not otherwise be required to qualify but for this Section 3(d), (II) subject itself to general taxation in any such jurisdiction, (III) file a general consent to service of process in any such jurisdiction, (IV) provide any undertakings that cause more than nominal expense or burden to the Company or (V) make any change in its charter or by-laws; (e) as promptly as practicable after becoming aware of such event, notify each Investor of the happening of any event of which the Company has knowledge, as a result of which the prospectus included in the Shelf Registration or Demand Registration, as then in effect, includes 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 under which they were made, not misleading, and use its best efforts promptly to prepare a supplement or amendment to the Registration Statement to correct such untrue statement or omission, and deliver a number of copies of such supplement or amendment to each Investor as such Investor may reasonably request; 7 (f) as promptly as practicable after becoming aware of such event, notify each Investor who holds Registrable Securities being sold (or, in the event of an Underwritten Offering, the managing underwriters) of the issuance by the SEC (or any state agency) of any stop order or other suspension of effectiveness of any Registration Statement (or state qualification) at the earliest possible time; (g) permit a single firm of counsel designated as selling shareholders' counsel by the Investors to review a Registration Statement and all amendments and supplements thereto a reasonable period of time prior to their filing with the SEC, PROVIDED, HOWEVER, any such objection to the filing of any Registration Statement or amendment thereto or any prospectus or supplement thereto shall be made by written notice (the "Objection Notice") delivered to the Company no later than three (3) Business Days after the party or parties asserting such objection receives draft copies of the documents that the Company proposes to file.

The Company shall not be required to disclose any confidential information in such Records to any Inspector until and unless such Inspector shall have entered into confidentiality agreements (in form and substance satisfactory to the Company) with the Company with respect thereto, substantially in the form of this Section 3(i). Each Investor agrees that it shall, upon learning that disclosure of such Records is sought in or by a court or governmental body of 8 competent jurisdiction, given prompt notice to the Company and allow the Company, at its expense, to undertake appropriate action to prevent disclosure of, or to obtain a protective order for, the Records deemed confidential; (j) use its best efforts either to (i) cause all the Registrable Securities covered by any Registration Statement to be listed on a national securities exchange, if the listing of such Registrable Securities is then permitted under the rules of such exchange, or (ii) secure the quotation of the Registrable Securities on the Nasdaq National Market if such quotation is then permitted under the rules of the Nasdaq; (k) provide a transfer agent and registrar, which may be a single entity, for the Registrable Securities not later than the effective date of any Registration Statement; (l) cooperate with the Investors who hold Registrable Securities being sold and the managing underwriter or underwriters, if any, to facilitate the timely preparation and delivery of certificates (not bearing any restrictive legends) representing Registrable Securities to be sold pursuant to the Shelf Registration or Demand Registration, as the case may be, and enable such certificates to be in such denominations or amounts as the case may be, and registered in such names as the managing underwriter or underwriters, if any, or the Investors may reasonable request; and (m) take all other reasonable actions necessary to expedite and facilitate disposition by the Investor of the Registrable Securities pursuant to the Registration Statement. 4.

If within five (5) business days prior to the filing date the Company has not received the Requested Information from an Investor (a "NON-RESPONSIVE INVESTOR"), then the Company may file the Shelf Registration or the Demand Registration, as the case may be, without including Registrable Securities of such Non-Responsive Investor; (b) Each Investor by such Investor's acceptance of the Registrable Securities agrees to cooperate with the Company as reasonably requested by the Company in connection with the preparation and filing of any Registration Statement hereunder, unless such Investor has notified the Company in writing of such Investor's election to exclude all of such Investor's Registrable Securities from the Registration Statement; 9 (c) Each Investor agrees that, upon receipt of any notice from the Company of the happening of any event of any kind described in Section 3(e) or 3(f), such Investor will immediately discontinue disposition of Registrable Securities pursuant to the Registration Statement covering such Registrable Securities until such Investor's receipt of the copies of the supplemented or amended prospectus contemplated by Section 3(e) or 3(f) and, if so directed by the Company, such Investor shall deliver to the Company (at the expense of the Company) or destroy (and deliver to the Company a certificate of destruction) all copies in such Investor's possession, of the prospectus covering such Registrable Securities current at the time of receipt of such notice; (d) No Investor may participate in any Underwritten Offering hereunder unless such Investor (i) agrees to sell such Investor's Registrable Securities on the basis provided in any underwriting arrangements approved by the Investors entitled hereunder to approve such arrangements, (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents reasonably required under the terms of such underwriting arrangements and (iii) agrees to pay its pro rata share of all underwriting discounts and commissions and other fees and expenses of investment bankers and any manager or managers of such underwriting and legal expenses of the underwriters applicable with respect to its Registrable Securities, in each case to the extent not payable by the Company pursuant to the terms of this Agreement; (e) No Investor shall include the Investor's Registrable Securities in any Registration Statement relating to a Demand Registration unless the Investor has at such time a current intent to sell such Registrable Securities, and by including such Registrable Securities in such Registration Statement, the Investor will be deemed to represent to the Company that the Investor has such intent.

In order to enforce the foregoing covenant, the Company shall have the right to place restrictive legends on the certificates representing the shares subject to this Section and to impose stop transfer instructions with respect to the Registrable Securities and such other shares of stock of each Investor (and the shares or securities of every other person subject to the foregoing restriction) until the end of such period. 5.

In the event any Registrable Securities are included in a Registration Statement under this Agreement: (a) To the extent permitted by law, the Company will indemnify and hold harmless each Investor who holds such Registrable Securities, the directors, if any, of such Investor, the officers, if any, of such Investor, each person, if any, who controls any Investor within the meaning of the Securities Act or the Exchange Act, and, in the case of a Demand Registration, if the Registration Statement is for an underwritten offering, any underwriter (as defined in the Securities Act) for the Investors, the directors, if any, of such underwriter and the officers, if any, of such underwriter, and each person, if any, who controls any such underwriter within the meaning of the Securities Act or the Exchange Act (each, an "Indemnified Person"), against any losses, claims, damages, expenses or liabilities (joint or several) (collectively, "Claims") to which any of them may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such Claims (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon any of the following statements, omissions or violations in any Registration Statement, or any post-effective amendment thereof, or any prospectus included therein: (i) any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement or any post-effective amendment thereof or the omission or alleged omission to state therein a material fact required to be stated therein or 11 necessary to make the statements therein not misleading, (ii) any untrue statement or alleged untrue statement of a material fact contained in any preliminary prospectus if used prior to the effective date of such Registration Statement, or contained in the final prospectus (as amended or supplemented, if the Company files any amendment thereof or supplement thereto with the SEC) or the omission or alleged omission to state therein any material fact necessary to make the statements made therein, in light of the circumstances under which the statements therein were made, not misleading or (iii) any violation or alleged violation by the Company of the Securities Act, any state securities law or any rule or regulation by the Company of the Securities Act, the Exchange Act or any state securities law (the matters in the foregoing clauses (i) through (iii) being, collectively, "Violations").

Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of the Indemnified Person and shall survive the transfer of the Registrable Securities by the Investors pursuant to Section 9. (b) In connection with any Registration Statement in which an Investor is participating, each such Investor agrees to indemnify and hold harmless, to the same extent and in the same manner set forth in Section 6(a), the Company, each of its directors, each of its officers who signs the Registration Statement, each person, if any, who controls the Company within the meaning of the Securities Act or the Exchange Act, any other shareholder and, in the case of a Demand Registration, any underwriter selling securities pursuant to the Registration Statement or any of its directors or officers or any person who controls such shareholder or underwriter within the meaning of the Securities Act or the Exchange Act (collectively and together with an Indemnified Person, an "Indemnified Party"), against any Claim to which any of them may become subject, under the Securities Act, the Exchange Act or otherwise, insofar as such Claim arises out of or is based upon (i) any Violation, in each case to the extent (and only to 12 the extent) that such Violation occurs in reliance upon and in conformity with written information furnished to the Company by such Investor expressly for use in connection with such Registration Statement; and such Investor will reimburse any legal or other expenses reasonably incurred by them in connection with investigating or defending any such Claim or (ii) any violation by any Investor of such Investor's obligations under this Agreement; PROVIDED, HOWEVER, that the indemnity agreement contained in this Section 6(b) shall not apply to amounts paid in settlement of any Claim if such settlement is effected without the prior written consent of such Investor, which consent shall not be unreasonably withheld. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Indemnified Party and shall survive the transfer of the Registrable Securities by the Investors pursuant to Section 9. Notwithstanding anything to the contrary contained herein, the indemnification agreement contained in this Section 6(b) with respect to any preliminary prospectus shall not inure to the benefit of any Indemnified Party if the untrue statement or omission of material fact contained in the preliminary prospectus was corrected on a timely basis in the prospectus, as then amended or supplemented. (c) The Company shall be entitled to receive indemnities from underwriters, selling brokers, dealer managers and similar securities industry professionals participating in any distribution, to the same extent as provided above, with respect to information such persons so furnished in writing by such persons expressly for inclusion in the Registration Statement. (d) Promptly after receipt by an Indemnified Person or Indemnified Party under this Section 6 of notice of the commencement of any action (including any governmental action), such Indemnified Person or Indemnified Party shall, if a Claim in respect thereof is to be made against any indemnifying party under this Section 6, deliver to the indemnifying party a written notice of the commencement thereof and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume control of the defense thereof with counsel mutually satisfactory to the indemnifying parties; PROVIDED, HOWEVER, that an Indemnified Person or Indemnified Party shall have the right to retain its own counsel, with the reasonable fees and expenses to be paid by the indemnifying party, if, in the reasonable opinion of counsel retained by the indemnifying party, the representation by such counsel of the Indemnified Person or Indemnified Party and the indemnifying party would be inappropriate due to actual or potential conflicts of interests between such Indemnified Person or Indemnified Party and any other party represented by such counsel in such proceeding. The Company shall pay for only one separate legal counsel for the Indemnified Persons; such legal counsel shall be selected by the Investors holding a majority in interest of the Registrable Securities and shall be approved by the Company, such approval not to be unreasonably withheld. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action shall not relieve such indemnifying party of any liability to the Indemnified Person or Indemnified Party under this Section 6, except to the extent that the indemnifying party is prejudiced in its ability to defend such action. The indemnification required by this Section 6 shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as such expense, loss, damage or liability is incurred and is due and payable. 7. CONTRIBUTION. To the extent any indemnification by an indemnifying party is prohibited or limited by law, the indemnifying party agrees to make the maximum contribution 13 with respect to any amounts for which it would otherwise be liable under Section 6 to the fullest extent permitted by law; PROVIDED, HOWEVER, that (a) no contribution shall be made under circumstances where the maker would not have been liable for indemnification under the fault standards set forth in Section 6, (b) no seller of Registrable Securities guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any seller of Registrable Securities who was not guilty of such fraudulent misrepresentation and (c) contribution by any seller of Registrable Securities shall be limited in amount to the net amount of proceeds received by such seller from the sale of such Registrable Securities. 8. REPORTS UNDER EXCHANGE ACT. With a view to making available to the Investors the benefits of Rule 144 promulgated under the Securities Act or any other similar rule or regulation of the SEC that may at any time permit the Investors to sell securities of the Company to the public without registration ("Rule 144"), the Company agrees to: (a) make and keep public information available, as those terms are understood and defined in Rule 144; (b) file with the SEC in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act; and (c) furnish to each Investor so long as such Investor owns Registrable Securities, promptly upon request, (i) a written statement by the Company that it has complied with the reporting requirements of Rule 144, the Securities Act and the Exchange Act, (ii) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company and (iii) such other information as may be reasonably requested to permit the Investors to sell such securities pursuant to Rule 144 without registration. 9. ASSIGNMENT OF THE REGISTRATION RIGHTS. The rights to have the Company register Registrable Securities other than Rights Shares pursuant to this Agreement shall be automatically assigned by the Investors to transferees or assignees of all of any portion of such securities only if: (a) the Investor agrees in writing with the transferee or assignee to assign such rights, and a copy of such agreement is furnished to the Company within a reasonable time after such assignment, (b) the Company is, within a reasonable time after such transfer or assignment, furnished with written notice of (i) the name and address of such transferee or assignee and (ii) the securities with respect to which such registration rights are being transferred or assigned, (c) immediately following such transfer or assignment the further disposition of such securities by the transferee or assignee is restricted under the Securities Act and applicable state securities laws, and (d) at or before the time the Company received the written notice contemplated by clause (b) of this sentence the transferee or assignee agrees in writing with the Company to be bound by all of the provisions contained herein and (e) the transfer or assignment is made in compliance with the transfer restrictions in any Subscription Agreement, Rights Agreement, Warrant Agreement, or Series A Preferred Purchase Agreement, as applicable. 14 10. AMENDMENT OF REGISTRATION RIGHTS. Any provision of this Agreement may be amended and the observance thereof may be waived (either generally or in a particular instance and either retroactively or prospectively), only with the written consent of the Company and Investors who hold a majority in interest of the Registrable Securities with each share of Series A Preferred and each Series A Share being treated as one security and each Warrant and each Warrant Share being treated as one security. Any amendment or waiver effected in accordance with this Section 10 shall be binding upon each Investor and the Company. 11. TERM. The term of this Agreement and the obligations of the parties hereunder (other than their obligations under Sections 5, 6 and 7, which will continue) will end (the "Registration Termination Date") (i) with respect to Registrable Securities other than Demand Shares or Holdover Securities, on the earlier to occur of (A) the sale of the Registrable Securities, or (B) at the end of the Effectiveness Period for the Shelf Registration, and (ii) with respect to the Demand Shares and Holdover Securities, on the earlier to occur of (A) the sale of the Demand Securities and Holdover Securities, or (B) 24 months from the date of issuance of such securities. In no event will the Company be required to register hereunder or maintain any registration hereunder of any Registrable Securities that are then eligible for resale under Rule 144. 12. MISCELLANEOUS. (a) A person or entity is deemed to be a holder of Registrable Securities whenever such person or entity owns of record such Registrable Securities.
