"REGISTRABLE SECURITIES" means the Warrant Shares and the Conversion Shares which have been, or which may from time to time be issued, upon exercise of the Warrants or conversion of the Convertible Note. e.

REGISTRATION. a. Mandatory Registration. The Company shall as soon as practicable following June 30, 2003, but no later than September 30, 2003, file the Registration Statement with the SEC. Buyers and their respective counsel shall have a reasonable opportunity to review and comment upon the Registration Statement prior to its filing. Buyers shall furnish all information reasonably requested by the Company for inclusion in the Registration Statement. The Company shall use commercially reasonable efforts to have the Registration Statement declared effective by the SEC within 90 days of the filing date. The Company shall use commercially reasonable efforts to keep the Registration Statement effective pursuant to Rule 415 promulgated under the 1933 Act and available for sales by Buyers of all of the Registrable Securities at all times until the earlier of (i) the date as of which any Buyer would, if not an affiliate of the Company, be able sell all of the Registrable Securities without restriction pursuant to Rule 144(k) promulgated under the 1933 Act (or successor thereto), or (ii) date on which Buyers shall have sold all the Registrable Securities (the "REGISTRATION PERIOD"). b. Rule 424 Prospectus. The Company shall, as required by applicable securities regulations, from time to time file with the SEC, pursuant to Rule 424 promulgated under the 1933 Act, the prospectus and prospectus supplements, if any, to be used in connection with sales of the Registrable Securities under the Registration Statement. Buyers and their counsel shall have a reasonable opportunity to review and comment upon such prospectus prior to its filing with the SEC. 3. RELATED OBLIGATIONS. With respect to the Registration Statement, the Company shall have the following obligations: a. The Company shall 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, which prospectus is to be filed pursuant to Rule 424 promulgated under the 1933 Act, as may be necessary to keep the Registration Statement effective at all times during the Registration Period. b. The Company shall permit Buyers to review and comment upon the Registration Statement and all amendments and supplements thereto at least two Business Days prior to their filing with the SEC. Each of the Buyers shall provide the Company with any comments or corrections to the Registration Statement, or any amendments or supplements thereto, within two Business Days from the date such Buyer receives the final version thereof. c. The Company shall furnish to Buyers, (i) promptly after the same is prepared and filed with the SEC, at least one copy of the Registration Statement and any amendment(s) thereto, including financial statements and schedules, and all exhibits, (ii) upon the effectiveness of any registration statement, 10 copies of the prospectus included in such registration statement and all amendments and supplements thereto (or such other number of copies as Buyers may reasonably request) and (iii) such other documents, including copies of any preliminary or final prospectus, as Buyers may reasonably request from time to time in order to facilitate the disposition of the Registrable Securities owned by Buyers. d. The Company shall use commercially reasonable efforts to (i) register and qualify the Registrable Securities covered by a registration statement under such other securities or "blue sky" laws of such jurisdictions in the United States as Buyers reasonably request, (ii) prepare and file in those jurisdictions, such amendments (including post-effective amendments) and supplements to such registrations and qualifications as may be necessary to maintain the effectiveness thereof during the Registration Period, (iii) take such other actions as may be necessary to maintain such registrations and qualifications in effect at all times during the Registration Period, and (iv) take all other actions reasonably necessary or advisable to qualify the Registrable Securities for sale in such jurisdictions; provided, however, that the Company shall not be required in connection therewith or as a condition thereto to (x) qualify to do business in any jurisdiction where it would not otherwise be required to qualify but for this Section 3(d), (y) subject itself to general taxation in any such jurisdiction, or (z) file a general consent to service of process in any such jurisdiction. e. As promptly as practicable after becoming aware of such event or facts, the Company shall notify Buyers in writing of the happening of any event or existence of such facts as a result of which the prospectus included in the Registration Statement, 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 promptly prepare and file with the SEC and with all other applicable "blue sky" authorities a supplement or amendment to such registration statement to correct such untrue statement or omission, and deliver 10 copies of such supplement or amendment to Buyers (or such other number of copies as Buyers may reasonably request). The Company shall also promptly notify Buyers in writing (i) when a prospectus or any prospectus supplement or post-effective amendment has been filed, and when the Registration Statement or any post-effective amendment has become effective, (ii) of any request by the SEC for amendments or supplements to the Registration Statement or related prospectus or related information, and (iii) of the Company's reasonable determination that a post-effective amendment to the Registration Statement would be appropriate. f. The Company shall use its commercially reasonable efforts to prevent the issuance of any stop order or other suspension of effectiveness of any registration statement, or the suspension of the qualification of any Registrable Securities for sale in any jurisdiction and, if such an order or suspension is issued, to obtain the withdrawal of such order or suspension at the earliest possible moment and to notify Buyers of the issuance of such order and the resolution thereof or its receipt of actual notice of the initiation or threat of any proceeding for such purpose. 4. OBLIGATIONS OF BUYERS. a. Each Buyer shall promptly furnish to the Company such information regarding itself, the Registrable Securities held by it and the intended method of disposition of the Registrable Securities held by it as shall be reasonably requested by the Company to effect the registration of such Registrable Securities, including information to be included in the Registration Statement, prospectus and all amendments and supplements thereto, and shall execute such documents in connection with such registration as the Company may reasonably request. b.

Each Buyer agrees that, upon receipt of any notice from the Company of the happening of any event or existence of facts of the kind described in Section 3(f) or the first sentence of 3(e), such Buyer will immediately discontinue disposition of Registrable Securities until Buyer's receipt of the copies of the supplemented or amended prospectus contemplated by Section 3(f) or the first sentence of 3(e). 5. EXPENSES OF REGISTRATION. All reasonable expenses, other than sales or brokerage commissions, incurred in connection with registrations, filings or qualifications pursuant to Sections 2 and 3, including, without limitation, all registration, listing and qualification fees, printing and accounting fees, and fees and disbursements of counsel for the Company, shall be paid by the Company. 6. INDEMNIFICATION. a. To the fullest extent permitted by law, the Company will, and hereby does, indemnify, hold harmless and defend each Buyer, each Person, if any, who controls a Buyer, the members, the directors, officers, partners, employees, agents, representatives of Buyers and each Person, if any, who controls Buyers within the meaning of the 1933 Act or the Securities Exchange Act of 1934, as amended (the "1934 ACT") and their respective successors and assigns (each, an "INDEMNIFIED PERSON"), against any losses, claims, damages, liabilities, judgments, fines, penalties, charges, costs, attorneys' fees, amounts paid in settlement or expenses, joint or several, (collectively, "CLAIMS") incurred in investigating, preparing or defending any action, claim, suit, inquiry, proceeding, investigation or appeal taken from the foregoing by or before any court or governmental, administrative or other regulatory agency, body or the SEC, whether pending or threatened, whether or not an indemnified party is or may be a party thereto ("INDEMNIFIED DAMAGES"), to which any of them may become subject insofar as such Claims (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon: (i) any untrue statement or alleged untrue statement of a material fact in the Registration Statement, or any post-effective amendment thereto or in any filing made in connection with the qualification of the offering under the securities or other "blue sky" laws of any jurisdiction in which Registrable Securities are offered ("BLUE SKY FILING"), or the omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) any untrue statement or alleged untrue statement of a material fact 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 1933 Act, the 1934 Act, any other law, including, without limitation, any state securities law, or any rule or regulation thereunder relating to the offer or sale of the Registrable Securities pursuant to the Registration Statement (the matters in the foregoing clauses (i) through (iii) being, collectively, "VIOLATIONS"). The Company shall reimburse each Indemnified Person promptly as such expenses are incurred and are due and payable, for any legal fees or other reasonable expenses incurred by them in connection with investigating or defending any such Claim. Notwithstanding anything to the contrary contained herein, the indemnification agreement contained in this Section 6(a): (i) shall not apply to a Claim by an Indemnified Person arising out of or based upon a Violation which occurs as a result of any untrue statement or omission of a material fact by either Buyer in information provided to the Company expressly for use in connection with the preparation of the Registration Statement, or any amendment thereof or supplement thereto; (ii) with respect to any superseded prospectus, shall not inure to the benefit of any such person from whom the person asserting any such Claim purchased the Registrable Securities that are the subject thereof (or to the benefit of any person controlling such person) if the untrue statement or omission of material fact contained in the superseded prospectus was corrected in the revised prospectus, as then amended or supplemented, prior to the purchase, and if such revised prospectus was timely made available by the Company pursuant to Section 3(c) or Section 3(e); (iii) shall not be available to the extent such Claim is based on a failure of an Indemnified Person to deliver or to cause to be delivered the prospectus made available by the Company, if such prospectus was timely made available by the Company pursuant to Section 3(c) or Section 3(e); and (iv) shall not apply to amounts paid in settlement of any Claim if such settlement is effected without the prior written consent of the Company, provided that such 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 the Indemnified Person and shall survive any transfer of the Registrable Securities by a Buyer pursuant to Section 9. b. In connection with the Registration Statement, each Buyer agrees to indemnify, hold harmless and defend, to the same extent and in the same manner as is 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 1933 Act or the 1934 Act and their respective successors and assigns (collectively and together with an Indemnified Person, an "INDEMNIFIED PARTY"), against any Claim or Indemnified Damages to which any of them may become subject, under the 1933 Act, the 1934 Act or otherwise, insofar as such Claim or Indemnified Damages arise out of or are based upon any Violation, in each case to the extent, and only to the extent, that such Violation (i) occurs in reliance upon and in conformity with information furnished to the Company by such Buyer expressly for use in connection with the Registration Statement, prospectus or amendment or supplement thereto, (ii) arises from an untrue statement or omission of material fact contained in a superseded prospectus, if the untrue statement or omission of material fact contained in the superseded prospectus was corrected in the revised prospectus, as then amended or supplemented, if such revised prospectus was timely made available by the Company pursuant to Section 3(c) or Section 3(e), (iii) arises as a result of such Buyer's failure to deliver or to cause to be delivered the prospectus made available by the Company, if such prospectus was timely made available by the Company pursuant to Section 3(c) or Section 3(e), or (iv) arises from the offer or sale or Registrable Securities under the securities or other "blue sky" laws of any jurisdiction in which such Buyer has not requested the Company to register and qualify the Registrable Securities pursuant to Section 3(d); and, subject to Section 6(d), such Buyer will reimburse promptly as such expenses are incurred and are due and payable any legal fees or other reasonable expenses incurred by them in connection with investigating or defending any such Claim; provided, however, that the indemnity agreement contained in this Section 6(b) and the agreement with respect to contribution contained in Section 7 shall not apply to amounts paid in settlement of any Claim if such settlement is effected without the prior written consent of such Buyer, provided that such 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 Buyer pursuant to Section 9. c. Promptly after receipt by an Indemnified Person or Indemnified Party under this Section 6 of notice of the commencement of any claim, investigation, inquiry, action or proceeding (including any governmental action or proceeding) involving a Claim, 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 party and the Indemnified Person or the Indemnified Party, as the case may be; provided, however, that an Indemnified Person or Indemnified Party shall have the right to retain its own counsel with the 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 differing interests between such Indemnified Person or Indemnified Party and any other party represented by such counsel in such proceeding. The Indemnified Party or Indemnified Person shall cooperate fully with the indemnifying party in connection with any negotiation or defense of any such action or claim by the indemnifying party and shall furnish to the indemnifying party all information reasonably available to the Indemnified Party or Indemnified Person which relates to such action or claim. The indemnifying party shall keep the Indemnified Party or Indemnified Person fully apprised at all times as to the status of the defense or any settlement negotiations with respect thereto. No indemnifying party shall be liable for any settlement of any action, claim or proceeding effected without its written consent, provided, however, that the indemnifying party shall not unreasonably withhold, delay or condition its consent. No indemnifying party shall, without the consent of the Indemnified Party or Indemnified Person, consent to entry of any judgment or enter into any settlement or other compromise which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party or Indemnified Person of a release from all liability in respect to such claim or litigation. Following indemnification as provided for hereunder, the indemnifying party shall be subrogated to all rights of the Indemnified Party or Indemnified Person with respect to all third parties, Persons, firms or corporations relating to the matter for which indemnification has been made. 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. 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 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: (i) no seller of Registrable Securities guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any seller of Registrable Securities who was not guilty of fraudulent misrepresentation; and (ii) 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 AND DISCLOSURE UNDER THE SECURITIES ACTS. With a view to making available to Buyers the benefits of Rule 144 promulgated under the 1933 Act or any other similar rule or regulation of the SEC that may at any time permit Buyers to sell securities of the Company to the public without registration ("RULE 144"), until the Warrants have been fully exercised or have expired, 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 and its officers under the 1933 Act and the 1934 Act so long as the Company remains subject to such requirements and the filing of such reports and other documents is required for the applicable provisions of Rule 144; and c. furnish to each Buyer so long as such Buyer owns Registrable Securities, promptly upon request, (i) a written statement by the Company that it and its officers have complied with the reporting and or disclosure provisions of Rule 144, the 1933 Act and the 1934 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 its officers, and (iii) such other information as may be reasonably requested to permit Buyers to sell such securities pursuant to Rule 144 without registration. 9. ASSIGNMENT OF REGISTRATION RIGHTS. The Company shall not assign this Agreement or any rights or obligations hereunder without the prior written consent of Buyers, including by merger or consolidation. A Buyer may not assign its rights under this Agreement without the written consent of the Company, other than to a permitted transferee of Buyer's Warrant. 10. AMENDMENT OF REGISTRATION RIGHTS. Provisions 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 the holders of a requisite majority interest of Registrable Securities. 11. MISCELLANEOUS. a. A Person is deemed to be a holder of Registrable Securities whenever such Person owns or is deemed to own of record such Registrable Securities.

The institution and maintenance of an action or judicial proceeding for, or pursuit of, provisional or ancillary remedies shall not constitute a waiver of the right of any party, even if it is the plaintiff, to submit the dispute to arbitration if such party would otherwise have such right. Each of the parties hereby submits unconditionally to the exclusive jurisdiction of the state and federal courts located in the County of Franklin, State of Ohio for purposes of this provision, waives objection to the venue of any proceeding in any such court or that any such court provides an inconvenient forum and consents to the service of process upon it in connection with any proceeding instituted under this Section 11(l) in the same manner as provided for the giving of notice under this Agreement.
