(b)Priority on Primary Registrations. If a Piggyback Registration is an underwritten primary registration on behalf of the Company, and the managing underwriters advise the Company in writing that in their opinion the number of securities requested to be included in such registration exceeds the number that can be sold in an orderly manner in such offering within a price range acceptable to the Company, the Company will include in such registration shares in the following order until such limitation has been met:first, the securities the Company proposes to sell;second, the Registrable Securities requested to be included in such registration,pro rataamong the holders of such Registrable Securities on the basis of the number of Shares owned by each such holder;third, the securities requested to be included in such registration by the Stockholders; andfourth, other securities requested to be included in such registration;providedthat in any event, after the IPO, the Holders of the Registrable Securities shall be entitled to have their Shares represent at least twenty-five percent (25%) of the total shares included in any such registration.

(c)Expiration of Piggyback Registration Rights. The “piggyback” registration rights granted to Holders of Registrable Securities under thisSection 2 shall expire at the later of (i) ninety (90) days after all Registrable Securities are freely tradeable to the public through a broker, dealer or market maker in compliance with Rule 144(k) under the Securities Act, without limitation (or any similar rule then in force) or (ii) five (5) years after the closing of the IPO.

3. Demand Registration.

(a)Requests for Registration.

(i) Subject to the terms and conditions of this Agreement, the Holders of a majority of the then outstanding Class C Investors’ Shares at any time after the earlier of (i) the consummation of the IPO or (ii) October 31, 2000 may request registration under the Securities Act of all or part of their Class C Investors’ Shares on Form S-1 or any similar long-form registration statement (“Long-Form Registration”) by delivering a written request to the Company to that effect;provided, however, that, in the case of any such Long-Form Registration, the aggregate offering value of all of the shares to be offered must be reasonably expected to equal at least Five Million Dollars ($5,000,000).

(ii) Subject to the terms and conditions of this Agreement, the Holders of at least twenty-five percent (25%) of the then outstanding Class F Investors’ Shares at any time after the earlier of (i) the consummation of an IPO or (ii) October 31, 2000, may request a Long Form Registration by delivering a written request to the Company to that effect; provided, however, that, in the case of any such Long Form Registration, the aggregate offering value of all of the shares to be offered must be reasonably expected to equal at least Five Million Dollars ($5,000,000).

(iii) Subject to the terms and conditions of this Agreement, the Holders of at least twenty-five percent (25%) of the then outstanding Class C Investors’

Shares and Biotech Shares at any time may request registration under the Securities Act of all or part of their Registrable Securities on Form S-2 (“S-2 Short-Form Registration”) or S-3 (“S-3 Short-Form Registration”) or any similar short-form registration statement (collectively, a“Short-Form Registration”), if available, by delivering a written request to the Company to that effect;provided, however, that, in the case of any such Short-Form Registration, the aggregate offering value of the Class C Investors’ Shares and Biotech Shares requested to be included in such registration pursuant toSection 3(a), including, without limitation,Section 3(a)(v), must be reasonably expected to equal at least Five Hundred Thousand Dollars ($500,000).

(iv) Subject to the terms and conditions of this Agreement, the Holders of the then outstanding Class F Investors’ Shares at any time may request a S-3 Short-Form Registration of their Class F Investors’ Shares, if available, by delivering a written request to the Company to that effect;provided, however, that, in the case of any such S-3 Short-Form Registration, the aggregate offering value of the Class F Investors’ Shares requested to be included in such registration pursuant toSection 3(a), including, without limitation,Section 3(a)(v), must be reasonably expected to equal at least Five Hundred Thousand Dollars ($500,000).

(v) If the Holders of Registrable Securities initiating a registration pursuant toSection 3(a) intend to distribute the Registrable Securities by means of an underwriting, they shall so advise the Company in their written notice. Within ten (10) days after receipt of any written request pursuant to (i), (ii), (iii) or (iv) above, the Company will give written notice of such request to all of the Investors and Biotech, and will include, subject to the terms ofSection 3(d), in any such registration that constitutes a Demand Registration all securities with respect to which the Company has received written requests from the Investors and Biotech, for inclusion therein within fifteen (15) days after receipt of the Company’s notice. Any Long-Form Registration and any Short-Form Registration requested pursuant to thisSection 3(a), other than a registration in which the Company sells any of its securities in a primary offering, are referred to herein, respectively, as a“Long-Form Demand Registration”, and a“Short-Form Demand Registration”. The Company may elect to include its securities in a primary offering in any registration requested pursuant to thisSection 3(a);provided, however, that if the Company sells any of its securities in a primary offering, such offering shall not be deemed to be a Demand Registration and shall be considered a Piggyback Registration and will be governed bySection 2.

(b) Long-Form Demand Registrations. The Holders of Class C Investors’ Shares may request one Long-Form Demand Registration pursuant to Section 3(a)(i), and the Holders of Class F Investors’ Shares may request two (2) Long-Form Demand Registrations pursuant toSection 3(a)(ii). The Company will pay the Registration Expenses therefor of the Company and the Holders of Investors’ Shares.

requirement of the SEC or other governmental agency or court for any reason); (ii) the conditions to closing specified in the purchase agreement or underwriting agreement entered into in connection with such registration statement are satisfied and (iii) the Holders are able to register and sell at least seventy-five percent (75%) of their desired Shares. Notwithstanding the terms of the preceding sentence, a registration which does not become effective after the Company has filed a registration statement with respect thereto solely by reason of the refusal to proceed of the Holders of Investors’ Shares (unless such refusal is due to the disclosure of adverse information concerning the Company after such demand is made) shall be deemed to have been effected by such Holders and count as a Long-Form Demand Registration under thisSection 3, unless the Holders of Investors’ Shares making such demand shall have elected to pay the Registration Expenses of the Holders of Investors’ Shares incurred in connection therewith.

(c) Short-Form Demand Registration. The Holders of Registrable Securities will be entitled to request pursuant toSection 3(a)(iii) orSection 3(a)(iv), respectively, no more than two (2) Short-Form Demand Registrations in any twelve (12) month period. The Company will pay the Registration Expenses therefor of the Company and the Holders of Registrable Securities in connection with any such registration. A registration will not count as one of the Short-Form Demand Registrations under thisSection 3(c) until it has become effective;providedthat in any event the Company will pay the Registration Expenses of the Company and the Holders of Registrable Securities in connection with any such registration initiated as a Short-Form Demand Registration. Notwithstanding the terms of the preceding sentence, a registration that does not become effective after the Company has filed a registration statement with respect thereto solely by reason of the refusal to proceed of the Holders of Registrable Securities (unless such refusal is due to the disclosure of adverse information concerning the Company after such demand is made) shall be deemed to have been effected by such Holders and count as a Short-Form Demand Registration under thisSection 3(c), unless the Holders of Registrable Securities making such demand shall have elected to pay the Registration Expenses of the Holders of Registrable Securities incurred in connection therewith.

(d) Priority on Demand Registrations. If a Demand Registration is an underwritten public offering and the managing underwriters advise the Company that in their opinion the number of Registrable Securities and other securities requested to be included exceeds the number of Registrable Securities and other securities which can be sold in an orderly manner in such offering without materially adversely affecting the price of the Shares to be sold in such registrations, the Company will include in such registration shares in the following order until such limitation has been met:first, the number of securities requested to be included therein by the Holders of Registrable Securities pro rata among Holders of Registrable Securities on the basis of the number of Shares owned by such Holders (the“Demanding Shareholders”),second, securities requested by the Company to be included in such registration pursuant to “piggyback” rights hereunder; andthird, other securities requested by the Stockholders to be included in such registration.

(e) Restrictions on Registrations.

(i) The Company may postpone for a reasonable period, not to exceed an aggregate of one hundred twenty (120) days in any twelve (12) month period, the filing or the effectiveness of a registration statement for a Demand Registration, if the Company determines reasonably and in good faith that such filing would have a material adverse effect on any proposal or plan of the Company to engage in any transaction,providedthat in such event the Holders of Investors’ Shares initially requesting such Demand Registration will be entitled to withdraw such request and, if such request is withdrawn, such Demand Registration will not count as a permitted Demand Registration hereunder, and the Company will pay all Registration Expenses in connection with such withdrawn registration. In addition, the Company shall not be required to effect any registration in accordance with the terms of this Agreement within one hundred eighty (180) days after the effective date of the IPO or ninety (90) days after the effective date of any subsequent primary offering (or combined primary and secondary offering) of its securities (other than a registration statement on Form S-8, or any successor forms or a registration on Form S-4 or relating to a Rule 145 transaction). The Company may only provide the Delay Notice only once in any twelve (12) month period.

(ii) The rights granted underSection 3(a)(iii) andSection 3(a)(iv) shall expire ninety (90) days after all Registrable Securities are freely tradeable to the public through a broker, dealer or market maker in compliance with Rule 144(k) under the Securities Act, without limitation (or any similar rule than in force).

(iii) The Company shall not be required to effect a Long-Form Demand Registration unless it is a firmly underwritten offering by an underwriter of nationally recognized standing (but not limited to “Tier 1” or “Tier 2” underwriters). The Company shall have the sole right to select such underwriter;provided,that in the event the Company has not selected an underwriter within thirty (30) days of the request for Demand Registration, the Demanding Shareholders may select such underwriter subject to approval of the Company not to be unreasonably withheld.

(f) The Company shall give prompt notice to all holders of Registrable Securities of the receipt of a request for registration pursuant to thisSection 3.

(c) Any person entitled to indemnification hereunder will (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified party and the indemnifying party may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed by the indemnifying party, the indemnified party will not be subject to any liability for any settlement made by the indemnifying party without its consent (but such consent will not be unreasonably withheld); provided, however, that any consent to entry of any judgment or entry into any settlement must include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a full release

from all liability in respect to such claim or litigation. An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim will not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim. The failure of any indemnified party to give notice as provided herein shall not relieve the indemnifying party of its obligations under this Section 7 unless the failure to give such notice is materially prejudicial to an indemnifying party’s ability to defend such action, and then in such case, it shall be relieved only to the extent of such material prejudice.

(d) The indemnification provided for under this Agreement will remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling person of such indemnified party and will survive the transfer of securities, the completion of any offering of Registrable Securities in a registration statement and the termination of this Agreement. The Company also agrees to make such provisions, as are reasonably requested by an indemnified party, for contribution to such party in the event the Company’s indemnification is unavailable for any reason.

8. Participation in Underwritten Registrations. No person may participate in any registration hereunder that is underwritten unless such person (a) agrees to sell such person’s securities on the basis provided in any underwriting arrangements approved by the person or persons entitled hereunder to approve such arrangements, and (b) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents required under the terms of such underwriting arrangements.

9. Reports Under the Securities Laws. With a view to making available to the Holders of Registrable Securities the benefits of Rule 144 promulgated under the Securities Act and any other rule or regulation of the SEC that may at any time permit such Holder to sell securities of the Company to the public without registration, the Company agrees to use its best efforts to:

(a) Make and keep public information available, as those terms are understood and defined in Rule 144 under the Securities Act, at all times subsequent to ninety (90) days after the effective date of any registration statement covering an underwritten public offering filed under the Securities Act by the Company;

(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, at any time after it is subject to such registration requirements; and

(c) Furnish to any such Holder so long as such Holder owns any of the Registrable Securities forthwith upon request a written statement by the Company that it has complied with the reporting requirements of Rule 144 (at any time after ninety (90) days after the effective date of the first registration statement filed by the Company for an offering of its securities to the general public), and of the Securities Act and the Exchange Act any time after it has become subject to such reporting requirements), a

copy of the most recent annual or quarterly report of the Company, and such other reports and documents so filed by the Company as may be reasonably requested by any such Holder in availing any such Holder of any rule or regulation of the SEC permitting the selling of any such securities without registration.

10. Certain Limitations in Connection with Future Grants of Registration Rights. From and after the date of this Agreement, the Company shall not enter into any agreement with any holder or prospective holder of any securities of the Company providing for the granting to such holder of registration rights unless such agreement is approved by the Holders of seventy-five percent (75%) of the Registrable Securities then outstanding. Notwithstanding the foregoing, any amendments or agreements that affect the rights of the Class C Preferred or grant rights which are senior to orpari passuto the rights of the Class C Preferred must be approved by Holders of at least seventy-five percent (75%) of the Class C Preferred, and any amendments or agreements that affect the rights of the Class F Preferred or grant rights which are senior to orpari passuto the rights of the Class F Preferred must be approved by Holders of at least seventy-five percent (75%) of the Class F Preferred.
