-2-

transaction), a written request from the Holders of at least twenty-five percent (25.0%) of the Company’s Registrable Securities then outstanding (including all shares of Common Stock into which such shares of Preferred Stock and then may have been converted) that the Company file a registration statement under the Act covering the registration of Registrable Securities, then the Company shall, within ten (10) days of the receipt thereof, give written notice of such request to all Holders and shall, subject to the limitations of Section 2.1.1, below, use its diligent best efforts to effect as soon as practicable, the registration under the Act of all Registrable Securities which the Holders request to be registered within twenty (20) days of the mailing of such written notice by the Company.

2.1.1 Exceptions. However, the Company shall not be obligated to take any action to effect any such registration, qualification or compliance pursuant to this Section 2.1:

A. If the minimum aggregate offering price of the Registrable Securities requested to be registered pursuant to such registration by all of the Holders is less than One Million Dollars ($1,000,000);

B. If the Company has effected two (2) such registrations pursuant to this Section 2.1, and such registrations have been declared or ordered effective; or

C. If the Company shall furnish to such Holders a certificate signed by the President of the Company stating that in the good faith judgment of the Board of Directors (or underwriters then engaged by the Company to conduct an offering within one hundred and eighty (180) days following the date of the Holders’ request hereunder) such requested registration, if implemented, would have a material adverse impact upon the Company or its stockholders, then the Company’s obligation to use its best efforts to register, qualify or comply under this Section 2.1 shall be deferred for a period not to exceed ninety (90) days from the date of receipt of written request from the Holders; provided, however, that the Company may not utilize this right more than once in any twelve-month period.

2.1.2 Underwriting. If the Holders initiating the registration request hereunder (the “Initiating Holders”) intend to distribute the Registrable Securities covered by their request by means of an underwriting, they shall so advise the Company as a part of their request made pursuant to this Section 2.1 and the Company shall include such information in the written notice referred to in Section 2.1, above. In such event, the right of any Holder to include his Registrable Securities in such registration shall be conditioned upon such Holder’s participation in the underwriting arrangements required by this Section 2.1, and the inclusion of such Holder’s Registrable Securities in the underwriting (unless otherwise mutually agreed by a majority in interest of the Initiating Holders and such Holder) shall be limited to the extent provided herein.

A. All Holders proposing to distribute their securities through such underwriting shall (together with the Company) enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting by a majority in interest of the Initiating Holders, provided that such underwriting agreement shall not provide for indemnification or contribution obligations on the part of the Holders greater than the obligations set forth in Section 2.8.2. Notwithstanding any other provision of this Section 2.1, if the managing underwriter advises the Initiating Holders in writing that marketing factors require a limitation of the number of shares to be underwritten, then the Company shall so advise all holders of Registrable Securities and the number of shares of Registrable Securities that may be included in the registration and underwriting shall be allocated among all Holders of Registrable Securities in proportion, as nearly as practicable, to the respective amounts of Registrable Securities held by such Holders at the time of filing the registration statement or in such other manner as shall be agreed to by the Holders of a majority of the Registrable Securities

-3-

proposed to be included in such registration, until all of the Registrable Securities proposed to be included in such registration are included in such registration. No Registrable Securities excluded from the underwriting by reason of the underwriter’s marketing limitation shall be included in such registration. To facilitate the allocation of shares in accordance with the above provisions, the Company or the underwriters may round the number of shares allocated to any Holder to the nearest one hundred (100) shares.

B. If any Holder of Registrable Securities disapproves of the terms of the underwriting, such person may elect to withdraw therefrom by written notice to the Company, the managing underwriter and the Initiating Holders. The Registrable Securities and/or other securities so withdrawn shall also be withdrawn from registration, and such Registrable Securities shall not be transferred in a public distribution prior to 90 days after the effective date of such registration, or such other shorter period of time as the underwriters may require.

2.2 Company Registration. If the Company proposes to register (including for this purpose a registration effected by the Company for stockholders other than the Holders) any of its stock or other securities under the Act in connection with the public offering of such securities solely for cash (other than a registration relating solely to the sale of securities to participants in a Company stock plan, or a registration on any form which does not include substantially the same information as would be required to be included in a registration statement covering the sale of the Registrable Securities, or a registration relating solely to a corporate reorganization or other similar Rule 145 transaction on Form S-4 or any similar form promulgated in the future), then the Company shall, at such time, promptly give each Holder written notice of such registration.

2.2.1 Request by Holder. Upon the written request of each Holder given within twenty (20) days after mailing of the written notice described in Section 2.2, above, by the Company, the Company shall cause to be registered under the Act all of the Registrable Securities that each such Holder has requested to be registered.

2.2.2 Underwriting. If the registration of which the Company gives notice is for a registered public offering involving an underwriting, the Company shall so advise the Holders as a part of the written notice given pursuant to Section 2.2. In such event the right of any Holder to registration pursuant to this Section 2.2 shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of Registrable Securities in the underwriting to the extent provided herein. All Holders proposing to distribute their securities through such underwriting shall (together with the Company and the other Holders distributing their securities through such underwriting) enter into an underwriting agreement in customary form with the managing underwriter selected for such underwriting by the Company, provided that such underwriting agreement shall not provide for indemnification or contribution obligations on the part of the Holders greater than the obligations set forth in Section 2.8.2. Notwithstanding any other provision of this Section 2.2, if the managing underwriter determines that marketing factors require a limitation of the number of shares to be underwritten, the managing underwriter may limit the Registrable Securities or other securities to be included in such registration; provided, however, that no such reduction shall reduce the amount of securities of the selling Holders included in the registration below five percent (5.0%) of the total amount of securities included in such registration, unless such offering is the initial public offering and the registration does not include shares of any other selling shareholders, in which event any or all of the Registrable Securities of the Holders may be excluded; provided, further, that if the number of shares of Registrable Securities permitted to be registered is reduced pursuant to the preceding sentence, then no persons may sell securities in such offering except for the Company and the Holders of Registrable Securities.

-4-

A. The Company shall so advise all Holders and other holders distributing their securities through such underwriting and the number of shares of Registrable Securities and other securities that may be included in the registration, and underwriting shall be allocated among all Holders in proportion, as nearly as practicable, to the respective amounts of Registrable Securities held by such Holders at the time of filing the registration statement. To facilitate the allocation of shares in accordance with the above provisions, the Company may round the number of shares allocated to any Holder or holder to the nearest 100 shares.

B. If any Holder disapproves of the terms of any such underwriting, he may elect to withdraw therefrom by written notice to the Company and the managing underwriter. Any securities excluded or withdrawn from such underwriting shall be withdrawn from such registration, and shall not be transferred in a public distribution prior to 90 days after the effective date of the registration statement relating thereto, or such other shorter period of time as the underwriters may require.

2.3 Form S-3 Registration.

2.3.1 Request for Registration. After its initial public offering, the Company shall use its best efforts to qualify for registration on Form S-3 or any comparable or successor form or forms. After the Company has qualified for the use of Form S-3, in addition to the rights contained in the foregoing portions of this Section 2, if any Holder or Holders request that the Company effect a registration on Form S-3 and any related or successor qualification or compliance with respect to all or a part of the Registrable Securities owned by such Holder or Holders, the Company shall promptly give written notice of the proposed registration, and any related qualification or compliance, to all other Holders. Upon the written request of each Holder given within twenty (20) days after mailing of written notice by the Company, the Company shall effect such registration and all such qualifications and compliance as may be so requested and as would permit or facilitate the sale and distribution of all or such portion of such Holder’s or Holders’ Registrable Securities. Registrations effected pursuant to this Section 2.3 shall not be counted as demands for registration or registrations effected pursuant to Section 2.1, above.

2.3.2 Exceptions. Notwithstanding the foregoing, the Company shall not be obligated to take any action to effect any such registration, qualification or compliance pursuant to this Section 2.3:

A. If the Holders, together with the holders of any other securities of the Company entitled to inclusion in such registration, propose to sell Registrable Securities and such other securities (if any) at an aggregate price to the public of less than Five Hundred Thousand Dollars ($500,000);

B. If the Company has already effected two (2) such registrations pursuant to this Section 2.3 within such twelve-month period, and such registrations have been declared or ordered effective; or

C. If the Company shall furnish to such Holders a certificate signed by the President of the Company stating that in the good faith judgment of the Board of Directors it would be seriously detrimental to the Company or its shareholders for a registration statement to be filed at such time, then the Company’s obligation to use its best efforts to register, qualify or comply under this Section 2.3 shall be deferred for a period not to exceed ninety (90) days from the date of receipt of written request from the Holders; provided, however, that the Company may not utilize this right more than once in any twelve-month period.

-5-

2.4 Obligations of the Company. Whenever required under this Section 2 to effect the registration of any Registrable Securities, the Company shall, as expeditiously as reasonably possible:

2.4.1 Prepare and file with the SEC a registration statement with respect to such Registrable Securities and use its best efforts to cause such registration statement to become effective, and, upon the request of the Holders of a majority of the Registrable Securities registered thereunder, keep such registration statement effective for up to one hundred twenty (120) days.

2.4.2 Prepare and file with the SEC such amendments and supplements to such registration statement and the prospectus used in connection with such registration statement as may be necessary to comply with the provisions of the Act with respect to the disposition of all securities covered by such registration statement.

2.4.3 Furnish to the Holders such numbers of copies of a prospectus, including a preliminary prospectus, in conformity with the requirements of the Act, and such other documents as they may reasonably request in order to facilitate the disposition of Registrable Securities owned by them.

2.4.4 Use its best efforts to register and qualify the securities covered by such registration statement under such other securities or Blue Sky laws of such jurisdictions as shall be reasonably requested by the Holders, provided that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of process in any such states or jurisdictions.

2.4.5 In the event of any underwritten public offering, enter into and perform its obligations under an underwriting agreement, in usual and customary form, with the managing underwriter of such offering.

2.4.6 Notify each Holder of Registrable Securities covered by such registration statement at any time when a prospectus relating thereto is required to be delivered under the Act of the happening of any event as a result of which the prospectus included in such 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 not misleading in the light of the circumstances then existing.

2.4.7 Furnish, at the request of any Holder requesting registration of Registrable Securities pursuant to this Section 2, on the date that such Registrable Securities are delivered to the underwriters for sale in connection with a registration pursuant to this Section 2, if such securities are being sold through underwriters, or, if such securities are not being sold through underwriters, on the date that the registration statement with respect to such securities becomes effective, an opinion, dated such date, of the counsel representing the Company for the purposes of such registration, and a letter dated as of such date, from the independent certified public accountant of the Company, each in form and substance as is customarily given to underwriters in an underwritten public offering, addressed to the underwriters, if any, and to the Holders requesting registration of Registrable Securities.

2.5 Furnish Information. It shall be a condition precedent to the obligations of the Company to take any action pursuant to this Section 2 with respect to the Registrable Securities of any selling Holder that such Holder shall furnish to the Company such information regarding itself, the Registrable Securities held by it, and the intended method of disposition of such securities as shall be required to effect the registration of such Holder’s Registrable Securities.

-6-

2.6 Expenses of Demand and Company Registration. The Company shall bear and pay:

2.6.1 Demand Registration. All expenses (other than underwriting discounts and commissions, which shall be paid out of the gross proceeds of such underwritten offering) including quoting in connection with registrations, filings, or qualifications pursuant to Section 2.1, above, including (without limitation) all registration, filing and qualification fees, printers’ and accounting fees, and fees and disbursements of accounts for the Company and reasonable fees of one special counsel selected by the Selling Holders; provided, however, that the Company shall not be required to pay for any expenses of any registration proceeding initiated pursuant to Section 2.1, above, if the registration request is subsequently withdrawn at the request of the Holders of the majority of the Registrable Securities to be registered therein (in which case all participating Holders shall bear such expenses), unless the Holders of the majority of the Registrable Securities agree to forfeit their right to a demand registration pursuant to Section 2.1, above; provided further, however, that if at the time of such withdrawal, the Holders have learned of a material adverse change in the condition, business, or prospects of the Company not known to the Holders at the time of their request, then such Holders shall not be required to pay any such expenses and shall retain their rights to initiate registration pursuant to Section 2.1, above.

2.6.2 Company Registration.

2.8 Indemnification. In the event any Registrable Securities are included in a registration statement under this Section 2:

2.8.1 Indemnity by Company. To the extent permitted by law, the Company will indemnify and hold harmless each Holder, the employees, officers, directors, agents and partners of such Holder, any underwriter (as defined in the Act) for such Holder and each person, if any, who controls such Holder or underwriter within the meaning of the Act or the Securities Exchange Act of 1934, as amended (the “1934 Act”), against any losses, claims, damages, or liabilities (joint or several) to which they may become subject under the Act, the 1934 Act or other federal or state law, insofar as such losses, claims, damages, or liabilities (or actions in respect thereof) arise out of or are based upon any of the following statements, omissions or violations (collectively a “Violation”): (i) any untrue statement or alleged untrue statement of a material fact contained in such registration statement, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto, (ii) 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 (iii) any violation or alleged violation by the Company of the Act, the 1934 Act, any state securities law or any rule or regulation promulgated under the Act, the 1934 Act or any state securities law; and the Company will pay to each such Holder, the officers, directors and partners of a Holder, underwriter or controlling person, as incurred, any legal or other

-7-

expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability, or action; provided, however, that the indemnity agreement contained in this Section 2.8.1 shall not apply to amounts paid in settlement of any such loss, claim, damage, liability, or action if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld), nor shall the Company be liable in any such case for any such loss, claim, damage, liability, or action to the extent that it arises out of or is based upon a Violation which occurs in reliance upon and in conformity with written information furnished expressly for use in connection with such registration by any such Holder, underwriter or controlling person.

2.8.2 Indemnity by Holder. To the extent permitted by law, each selling Holder will indemnify and hold harmless the Company, each of its directors, each of its officers who has signed the registration statement, each person, if any, who controls the Company within the meaning of the Act, any underwriter, any other Holder selling securities in such registration statement and any controlling person of any such underwriter or other Holder, against any losses, claims, damages, or liabilities (joint or several) to which any of the foregoing persons may become subject, under the Act, the 1934 Act, or other federal or state law, insofar as such losses, claims, damages, or liabilities (or actions in respect thereto) arise out of or are 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 by such Holder expressly for use in connection with such registration; and each such Holder will pay, as incurred, any legal or other expenses reasonably incurred by any person intended to be indemnified pursuant to this Section 2.8.2, in connection with investigating or defending any such loss, claim, damage, liability, or action; provided, however, that the indemnity agreement contained in this Section 2.8.2 shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Holder, which consent shall not be unreasonably withheld; provided, that, in no event shall the total amount of any indemnity under this Section 2.8.2 exceed the net proceeds from the offering received by such Holder.

2.8.3 Indemnity Procedure. Promptly after receipt by an indemnified party under this Section 2.8 of notice of the commencement of any action (including any governmental action), such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this Section 2.8, 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 the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified party shall have the right to retain its own counsel, with the fees and expenses to be paid by the indemnifying party, if representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential differing interests between such indemnified party and any other party represented by such counsel in such proceeding. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action, if materially prejudicial to its ability to defend such action, shall relieve such indemnifying party of any liability to the indemnified party under this Section 2.8, but the omission so to deliver written notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise than under this Section 2.8.

2.8.4 Contribution. In order to provide for just and equitable contribution to joint liability under the Act in any case in which either (i) any Holder exercising rights under this Agreement, or any controlling person of any such Holder, makes a claim for indemnification pursuant to this Section 2.8 but it is judicially determined (by the entry of a final judgment or decree by a court of competent jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that such indemnification may not be enforced in such case notwithstanding the fact that this Section 2.8 provides for indemnification in such case, or (ii) contribution under

-8-

the Act may be required on the part of any such selling Holder or any such controlling person in circumstances for which indemnification is provided under this Section 2.8; then, and in each such case, the Company and such Holder will contribute to the aggregate losses, claims, damages or liabilities to which they may be subject (after contribution from others) in such proportion, so that the Holder is responsible for and shall contribute to the amount paid or payable by such Indemnified Party as a result of such loss, liability, claim, damage or expense in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party on the one hand and of the Indemnified Party on the other in connection with the statements or omissions which resulted in such loss, liability, claim, damage or expense as well as any other relevant equitable considerations. The relative fault of the Indemnifying Party and of the Indemnified Party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the Indemnifying Party or by the Indemnified Party and the party’s relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and other selling Holders are responsible for the remaining portion, provided, however, that, in any such case, (A) no such Holder will be required to contribute any amount in excess of the public offering price of all such Registrable Securities offered and sold by such Holder pursuant to such registration statement; and (B) no person or entity guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) will be entitled to contribution from any person or entity who was not guilty of such fraudulent misrepresentation.

2.8.5 Survival. The obligations of the Company and Holders under this Section 2.8 shall survive the completion of any offering of Registrable Securities in a registration statement under this Section 2, and otherwise.

2.9 Reports Under Securities Exchange Act of 1934. With a view to making available to the Holders the benefits of Rule 144 promulgated under the Act and any other rule or regulation of the SEC that may at any time permit a Holder to sell securities of the Company to the public without registration or pursuant to a registration on Form S-3, the Company agrees to:

2.9.1 Make and keep public information available, as those terms are understood and defined in SEC Rule 144, at all times after one hundred eighty (180) days after the effective date of the first registration statement filed by the Company for the offering of its securities to the general public;

2.9.2 Take such action, including the voluntary registration of its Common Stock under Section 12 of the 1934 Act, as is necessary to enable the Holders to utilize Form S-3 for the sale of their Registrable Securities, such action to be taken as soon as practicable after the end of the fiscal year in which the first registration statement filed by the Company for the offering of its securities to the general public is declared effective;

2.9.3 File with the SEC in a timely manner all reports and other documents required of the Company under the Act and the 1934 Act; and

2.9.4 Furnish to any Holder, so long as the Holder owns any Registrable Securities, forthwith upon request (i) a written statement by the Company that it has complied with the reporting requirements of SEC Rule 144 (at any time after one hundred eighty (180) days after the effective date of the first registration statement filed by the Company), the Act and the 1934 Act (at any time after it has become subject to such reporting requirements), or that it qualifies as a registrant whose securities may be resold pursuant to Form S-3 (at any time after it so qualifies), (ii) a copy of the most recent annual or quarterly report of the Company and

-9-

such other reports and documents so filed by the Company, and (iii) such other information as may be reasonably requested in availing any Holder of any rule or regulation of the SEC which permits the selling of any such securities without registration or pursuant to such form.

2.10 “Market Stand-Off” Agreement. Each Holder of Registrable Securities hereby agrees that, during such period as is determined by the Company’s underwriters (not to exceed 180 days following the effective date of the first registration statement filed by the Company under the Act covering Common Stock (or other securities) to be sold on the Company’s behalf to the public in an underwritten initial public offering), it shall not, to the extent requested by the Company, sell or otherwise transfer or dispose of (other than to a donee who agrees to be similarly bound) any Common Stock of the Company held by it at any time during such period except Common Stock included in such registration; provided, however, that each officer and director of the Company and each holder of one percent (1.0%) or more of the Company’s outstanding equity securities enters into a similar agreement. In order to enforce the foregoing covenants, the Company may impose stop-transfer instructions with respect to the Registrable Securities of each Holder (and the shares or securities of every other person subject to the foregoing restriction) until the end of any such period.

2.11 Waivers and Amendments of Registration Rights. Any term of this Section 2 may be amended and the observance of any term of this Section 2 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 at least a majority of the shares of Registrable Securities then outstanding. Any amendment or waiver effected in accordance with this Section 2.11 shall be binding upon the Company and each Holder of rights under this Section 2.

2.12 Termination of Registration Rights. No Holder shall be entitled to exercise any right provided for in this Section 2 after (i) five (5) years following the consummation of the sale of securities pursuant to a registration statement filed by the Company under the Act in connection with the initial firm commitment underwritten offering of its securities to the general public, or (ii) the first date as of which Holder may sell all of Holders of Registrable Securities within any period of ninety (90) consecutive days pursuant to Rule 144.
