Pursuant to Section 5.12 of the Merger Agreement, the Company agreed to provide the Stockholders certain registration rights as provided herein; WHEREAS, as an inducement for 3rd Rail to enter into the Merger Agreement, the Company desires to grant the registration rights to the Stockholders as contained herein; NOW, THEREFORE, in consideration of the promises and the mutual covenants contained herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Company and the Stockholders hereby agree as follows: 1. Definitions. Capitalized terms used herein and not otherwise defined herein shall have the respective meanings set forth in the Merger Agreement. As used in this Agreement, the following terms shall have the following meanings: (a) "Holders" are stockholders of the Company who, by virtue of agreements with the Company, are entitled to include their securities in certain Registration Statements filed by the Company. (b) "Investors" means the Stockholders and any transferees or assignees of the Investors who agree to become bound by the provisions of this Agreement in accordance with Section 8 hereof. (c) "Registrable Securities" means all of the following to the extent the same have not been sold to the public (i) any and all Merger Shares or (ii) stock issued in respect of the stock referred to in (i) as a result of a stock split, stock dividend, recapitalization or combination. (d) "Registration Period" means the period between the effective date of a Registration Statement and the earlier of (i) the date on which all of the Registrable Securities have been sold, or (ii) for each individual Investor, the date on which all the Registrable Securities relating to the Merger Shares (in the opinion of Company counsel) may be immediately sold without registration and without restriction as to the number of Registrable Securities to be sold pursuant to Rule 144 as promulgated under the 1933 Act ("Rule 144") or otherwise. (e) "Registration Statement" means, collectively, each registration statement filed with the Securities and Exchange Commission (the "SEC") under the 1933 Act pursuant to the terms hereof. (f) The terms "register," "registered," and "registration" refer to a registration effected by preparing and filing a Registration Statement or Statements in compliance with the 1933 Act and pursuant to Rule 415 as promulgated under the 1933 Act or any successor rule providing for offering securities on a continuous basis ("Rule 415") and applicable rules and regulations thereunder, and the declaration or ordering of effectiveness of such Registration Statement by the SEC. 2. Registration. (a) Mandatory Registration. The Company shall file pursuant to its obligations under the Merger Agreement, within sixty (60) days of the Closing Date a Registration Statement on Form S-3 (or, if such form is unavailable for such a registration, on such other form as is available for such a registration) with the SEC registering for resale Registrable Securities and any other securities of the Company which are held by Holders who are entitled to include securities in such registration. The Company shall use reasonable best efforts to cause such Registration Statement to be declared effective by the SEC as soon as practicable after filing. Such reasonable best efforts shall include, but not be limited to, promptly responding to all comments received from the staff of the SEC and filing of documents and supplements as soon as commercially practicable. Should the Company receive notification from the SEC that the Registration Statement will receive no action or no review from the SEC, the Company shall cause such Registration Statement to become effective within five (5) business days of such SEC notification. Once declared effective by the SEC, the Company shall cause such Registration Statement to remain effective throughout the Registration Period, except as otherwise permitted pursuant to Section 3(a). (b) Eligibility for Form S-3. The Company represents and warrants that it meets the requirements for the use of Form S-3 for registration of the sale by the Investors of the Registrable Securities. The Company shall file all reports required to be filed by the Company with the SEC in a timely manner so as to preserve its eligibility for the use of Form S-3. In the event that Form S-3 is not available for sale by the Investors of the Registrable Securities, then the Company (i) with the consent of the Investors holding a majority of the Registrable Securities pursuant to Section 2(a), shall register the sale of the Registrable Securities on another appropriate form and (ii) the Company shall undertake to register the Registrable Securities on Form S-3 as soon as such form is available, provided that the Company shall maintain the effectiveness of the Registration Statement then in effect until such time as a Registration Statement on Form S-3 covering the Registrable Securities has been declared effective by the SEC. 3. Additional Obligations of the Company. In connection with the registration of the Registrable Securities, the Company shall have the following additional obligations: (a) The Company shall keep the Registration Statement effective pursuant to Rule 415 under the 1933 Act at all times during the Registration Period. Notwithstanding the foregoing, the Company may by written notice (a "Shelf Blackout Right") require that the Investors immediately cease sales of shares pursuant to the Registration Statement and use of the prospectus under the Registration Statement at any time that (i) the Company becomes engaged in business activity or negotiation which is not disclosed in the Registration Statement (or the prospectus included therein) which the Company reasonably believes must be disclosed therein under applicable law and which the Company desires to keep confidential for business purposes, (ii) the Company determines that a particular disclosure so determined to be required to be disclosed therein would be premature or would adversely affect the Company or its business or prospects, (iii) the Company has knowledge of an event as a result of which the prospectus included in the Registration Statement as then in effect would include 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 or (iv) the Registration Statement otherwise can no longer be used under the existing rules and regulations promulgated under the Securities Act. The Company shall not be required to disclose to the Holders which of the reasons specified in clauses (i), (ii), (iii) or (iv) above are the basis for requiring a suspension of sales hereunder. Notwithstanding the foregoing, until the elapse of the Registration Period, the Company may only exercise the Shelf Blackout Right based upon (x) the good faith judgment of the Board of Directors pursuant to their fiduciary obligations or (y) the advice of counsel that the exercise of such Shelf Blackout Right is necessary in order to enable the Company to amend the registration statement to comply with the existing rules and regulations promulgated under the Securities Act. Upon receipt of a notice of a Shelf Blackout Right, the Investors will forthwith discontinue, for a period of up to twenty (20) consecutive business days, disposition of such Registrable Securities covered by such Registration Statement or prospectus until advised in writing by the Company that use of the applicable prospectus may be resumed, and until each such Investor has received notice from the Company of the termination of the need for a Shelf Blackout Right. Following the delivery of any notice of a Shelf Blackout Right, Company shall use all reasonable efforts to ensure that the use of the prospectus may be resumed as soon as practicable, and in any event shall not be entitled to require the Investors to suspend use of any prospectus during Deferral Period for more than thirty (30) business days in any twelve (12) month period. (b) The Registration Statement (including any amendments or supplements thereto and prospectuses contained therein) filed by the Company 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. Except as otherwise provided in Section 3(a) herein, 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 as may be necessary to permit sales pursuant to the Registration Statement at all times during the Registration Period, and, during such period, shall comply with the provisions of the 1933 Act with respect to the disposition of all Registrable Securities of the Company covered by the Registration Statement until the termination of the Registration Period, or if earlier, 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) The Company shall furnish to each Investor whose Registrable Securities are included in the Registration Statement and its legal counsel (i) promptly after the same is prepared and publicly distributed, filed with the SEC or received by the Company, one copy of the Registration Statement (and any amendment thereto); and each preliminary prospectus and final prospectus (and each amendment or supplement thereto); and (ii) 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) The Company shall use its reasonable best efforts to (i) register and qualify the Registrable Securities covered by the Registration Statement under such other securities or blue sky laws of such jurisdictions as each Investor who holds (or has the right to hold) Registrable Securities being offered 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. Notwithstanding the foregoing provision, the Company shall not be required in connection therewith or as a condition thereto to (i) qualify 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 material expense or burden to the Company, or (v) make any change in its charter or bylaws, which in each case the Board of Directors of the Company determines to be contrary to the best interests of the Company and its stockholders. (e) In the event Investors who hold a majority in interest of the Registrable Securities being offered in an offering pursuant to a Registration Statement or any amendment or supplement thereto under Section 2(a) select underwriters reasonably acceptable to the Company for such offering, the Company shall enter into and perform its obligations under an underwriting agreement in usual and customary form including, without limitation, customary indemnification and contribution obligations, with the managing underwriter of such offering. (f) Subject to the Company's rights under Section 3(a), the Company shall use its reasonable best efforts to prevent the issuance of any stop order or other suspension of effectiveness of a Registration Statement and, if such an order is issued, shall use its reasonable best efforts to obtain the withdrawal of such order at the earliest possible time and to notify each Investor who holds Registrable Securities being sold (or, in the event of an underwritten offering, the managing underwriters) of the issuance of such order and the resolution thereof. (g) The Company shall permit a single firm of counsel designated by the Investors who hold a majority in interest of the Registrable Securities being sold pursuant to such registration to review the Registration Statement and all amendments and supplements thereto (as well as all requests for acceleration or effectiveness thereof) a reasonable period of time prior to their filing with the SEC, and shall not file any document in a form to which such counsel reasonably objects, unless required by law in the opinion of the Company's counsel. The sections of such Registration Statement covering information with respect to the Investors, the Investors' beneficial ownership of securities of the Company or the Investors' intended method of disposition of Registrable Securities shall conform to the information provided to the Company by each of the Investors. (h) At the request of the Investors who hold a majority in interest of the Registrable Securities being sold pursuant to such registration, the Company shall furnish on the date that Registrable Securities are delivered to an underwriter for sale in connection with the Registration Statement (i) a letter, dated such date, from the Company's independent certified public accountants in form and substance as is customarily given by independent certified public accountants to underwriters in an underwritten public offering, addressed to the underwriters; and (ii) an opinion, dated such date, from counsel representing the Company for purposes of such Registration Statement, in form and substance as is customarily given in an underwritten public offering, addressed to the underwriters and Investors. (i) The Company shall make available for inspection by any Investor whose Registrable Securities are being sold pursuant to such registration, any underwriter participating in any disposition pursuant to the Registration Statement, and any attorney, accountant or other agent retained by any such Investor or underwriter (collectively, the "Inspectors"), all pertinent financial and other records, pertinent corporate documents and properties of the Company (collectively, the "Records"), as shall be reasonably deemed necessary by each Inspector to enable each Inspector to exercise its due diligence responsibility, and cause the Company's officers, directors and employees to supply all information which any Inspector may reasonably request for purposes of such due diligence; provided, however, that each Inspector shall hold in confidence and shall not make any disclosure (except to an Investor) of any Record or other information which the Company determines in good faith to be confidential, and of which determination the Inspectors are so notified, unless (i) the disclosure of such Records is necessary to avoid or correct a misstatement or omission in any Registration Statement, (ii) the release of such Records is ordered pursuant to a subpoena or other order from a court or government body of competent jurisdiction, or (iii) the information in such Records has been made generally available to the public other than by disclosure in violation of this or any other agreement (to the knowledge of the relevant Investor). 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. Each Investor agrees that it shall, upon learning that disclosure of such Records is sought in or by a court or governmental body of competent jurisdiction or through other means, give prompt notice to the Company and allow the Company, at the Company's expense, to undertake appropriate action to prevent disclosure of, or to obtain a protective order for, the Records deemed confidential. Nothing herein shall be deemed to limit the Investor's ability to sell Registrable Securities in a manner which is otherwise consistent with applicable laws and regulations. (j) The Company shall hold in confidence and shall not make any disclosure of information concerning an Investor provided to the Company pursuant hereto unless (i) disclosure of such information is necessary to comply with federal or state securities laws, (ii) the disclosure of such information is necessary to avoid or correct a misstatement or omission in any Registration Statement, (iii) the release of such information is ordered pursuant to a subpoena or other order from a court or governmental body of competent jurisdiction, or (iv) such information has been made generally available to the public other than by disclosure in violation of this or any other agreement or (v) such Investor consents to the form and content of any such disclosure. The Company agrees that it shall, upon learning that disclosure of such information concerning an Investor is sought in or by a court or governmental body of competent jurisdiction or through other means, give prompt notice to such Investor prior to making such disclosure and allow such Investor, at its expense, to undertake appropriate action to prevent disclosure of, or to obtain a protective order for, such information. (k) The Company shall cause the listing and the continuation of listing of all the Registrable Securities covered by the Registration Statement on the Nasdaq National Market System, the Nasdaq Small Cap Market, the New York Stock Exchange, the American Stock Exchange or any successor national exchange or market, and cause the Registrable Securities to be quoted or listed on each additional national securities exchange or quotation system upon which the Common Stock is then listed or quoted. (l) The Company shall provide a transfer agent and registrar, which may be a single entity, for the Registrable Securities not later than the effective date of the Registration Statement. (m) At the request of any Investor, the Company shall promptly prepare and file with the SEC such amendments (including post-effective amendments) and supplements to a Registration Statement and the prospectus used in connection with the Registration Statement as may be necessary in order to change the plan of distribution set forth in such Registration Statement. (n) The Company shall comply with all applicable laws related to a Registration Statement and offering and sale of securities and all applicable rules and regulations of governmental authorities in connection therewith (including, without limitation, the 1933 Act and the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and the rules and regulations promulgated by the SEC). (o) The Company shall take all other reasonable actions as any Investor or the underwriters, if any, may reasonably request to expedite and facilitate disposition by such Investor of the Registrable Securities pursuant to the Registration Statement. (p) Within two (2) business days after the Registration Statement which includes the Registrable Securities is ordered effective by the SEC, the Company shall deliver, and shall cause legal counsel for the Company to deliver, to the transfer agent for such Registrable Securities (with copies to the Investors whose Registrable Securities are included in such Registration Statement) confirmation that the Registration Statement has been declared effective by the SEC. 4. Obligations of the Investors. In connection with the registration of the Registrable Securities, the Investors shall have the following obligations: (a) It shall be a condition precedent to the obligations of the Company to complete the registration pursuant to this Agreement with respect to the Registrable Securities of each Investor that such Investor shall 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 required to effect the registration of the Registrable Securities. At least ten (10) business days prior to the first anticipated filing date of the Registration Statement, the Company shall notify each Investor of the information the Company requires from each such Investor (the "Requested Information") if such Investor elects to have any of such Investor's Registrable Securities included in the Registration Statement. 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 Registration Statement 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 the 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. (c) Each Investor agrees that, upon receipt of any notice from the Company of the kind described in Section 3(a), such Investor will immediately discontinue disposition of Registrable Securities pursuant to the Registration Statement covering such Registrable Securities until (i) the Investor has received the notice of termination of the Shelf Blackout Right from the Company required under Section 3(a), 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 (other than a limited number of file copies), of the prospectus covering such Registrable Securities current at the time of receipt of such notice. (d) Without limiting any Investor's rights under Section 2(a) hereof, no Investor may participate in any underwritten distribution 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 underwriter 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. 5. Expenses of Registration. All reasonable expenses, other than underwriting discounts and commissions, incurred in connection with registrations, filings or qualifications pursuant to Sections 2 and 3, including, without limitation, all registration, listing and qualifications fees and printers and accounting fees, the fees and disbursements of counsel for the Company shall be borne and paid by the Company. Notwithstanding the foregoing, the Investors participating in any registrations, filings or qualifications pursuant to sections 2 and 3 shall pay all fees, underwriting discounts, commissions and disbursements of its own counsel and any investment bankers on a pro rata basis based on the number of shares proposed to be sold under the Registration Statement. 6. Indemnification. 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 1933 Act or the Exchange Act, any underwriter (as defined in the 1933 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 1933 Act or the Exchange Act (each, an "Indemnified Person"), against any losses, claims, damages, expenses or liabilities (joint or several) (collectively together with actions, proceedings or inquiries by any regulatory or self- regulatory organization, whether commenced or threatened in respect thereof, "Claims") to which any of them become subject under the 1933 Act, the Exchange Act or otherwise, insofar as such Claims arise out of or are based upon any of the following statements, omissions or violations in the 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 the 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 necessary to make the statements therein not misleading, (ii) any untrue statement or alleged untrue statement of a material fact contained in the 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 Exchange Act or any other law, including without limitation any state securities law or any rule or regulation thereunder (the matters in the foregoing clauses (i) through (iii) being, collectively, "Violations"). Subject to the restrictions set forth in Section 6(c) with respect to the number of legal counsel, the Company shall reimburse the Investors and each such underwriter or controlling person and each such other 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): (A) shall not apply to a Claim arising out of or based upon a Violation which occurs in reliance upon and in conformity with information furnished in writing to the Company by any Indemnified Person expressly for use in connection with the preparation of the Registration Statement or any such amendment thereof or supplement thereto, if such prospectus was timely made available by the Company pursuant to Section 3(c) hereof; and (B) shall not apply to amounts paid in settlement of any Claim if such settlement is effected without the prior written consent of the Company, 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 the Indemnified Persons and shall survive the transfer of the Registrable Securities by the Investors pursuant to Section 8. (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 1933 Act or the Exchange Act, and any other stockholder selling securities pursuant to the Registration Statement or any of its directors or officers or any person who controls such stockholder within the meaning of the 1933 Act or the Exchange Act (an "Indemnified Party" and, collectively, "Indemnified Parties"), against any Claim to which any of them may become subject, under the 1933 Act, the Exchange Act or otherwise, insofar as such Claim arises out of or is based upon any Violation, in each case to the extent (and only to 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 subject to Section 6(c), such Investor will promptly reimburse any legal or other expenses (promptly as such expenses are incurred and due and payable) reasonably incurred by all Indemnified Parties in connection with investigating or defending any such Claim; 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; provided further, however, that the Investor shall be liable under this Agreement (including this Section 6(b) and Section 7) for only that amount of a Claim as does not exceed the net proceeds actually received by such Investor as a result of the sale of Registrable Securities pursuant to such Registration Statement. 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 8. (c) 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 made against any indemnifying party under this Section 6, deliver to the indemnifying party a written notice of the commencement thereof and this 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 and the Indemnified Person or the Indemnified Party, as the case may be; provided, however, that such Indemnified Party shall diligently pursue such defense and that such Indemnified Party shall not be entitled to assume such defense and 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 conflicts of interest between such Indemnified Person or Indemnified Party and any other party represented by such counsel in such proceeding or the actual or potential defendants in, or targets of, any such action including both the Indemnified Person or the Indemnified Party and any such Indemnified Person or Indemnified Party reasonably determines that there may be legal defenses available to such Indemnified Person or Indemnified Party which are different from or in addition to those available to such indemnifying party. The Company shall pay for only one separate legal counsel for the Investors; such legal counsel shall be selected by the Investors holding a majority in interest of the Registrable Securities. 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 provided for herein 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 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, (ii) 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 such fraudulent misrepresentation, and (iii) contribution (together with any indemnification or other obligations under this Agreement) 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. Assignment of Registration Rights. The rights of the Investors hereunder, including the right to have the Company register Registrable Securities pursuant to this Agreement shall be automatically assigned by the Investors to transferees or assignees of all or any portion of such securities only if (i) 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, (ii) the Company is, within a reasonable time after such transfer or assignment, furnished with written notice of the name and address of such transferee or assignee and the securities with respect to which such registration rights are being transferred or assigned, (iii) following such transfer or assignment the further disposition of such securities by the transferee or assignee is restricted under the 1933 Act and applicable state securities laws, (iv) at or before the time the Company received the written notice contemplated by clause (ii) of this sentence, the transferee or assignee agrees in writing with the Company to be bound by all of the provisions contained herein and (v) such transfer shall have been made in accordance with the applicable requirements of the Merger Agreement. 9. 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 Investors who hold a majority interest of the Registrable Securities (but not an Investor who no longer owns any Registrable Securities and who is not affected by such amendment or waiver). Any amendment or waiver effected in accordance with this Section 9 shall be binding upon each Investor and the Company. Notwithstanding the foregoing, no amendment or waiver shall retroactively affect any Investor without its comment or prospectively adversely affect any Investor who no longer owns any Registrable Securities without its consent. 10. Miscellaneous. (a) Conflicting Instructions. A person or entity is deemed to be a holder of Registrable Securities whenever such person or entity owns of record such Registrable Securities.
