Incidental Registration. ----------------------- (a) Right to Include Common Stock.

Upon the written request of any such holders of Registrable Securities made within 15 days of the date of the foregoing notice from the Company (which request shall specify the aggregate number of the Registrable Securities to be registered and will also specify the intended method of disposition thereof), the Company will effect the registration under the Securities Act of all Registrable Securities which the Company has been so requested to register by the holders thereof (an "Incidental ---------- Registration"), to the extent required to permit the public disposition (in - ------------ accordance with such intended methods thereof) of the Registrable Securities to be so registered; provided that (i) if, any time after giving written notice of its intention to register shares of Common Stock and prior to the effective date of the Registration Statement filed in connection with such registration, the Company shall determine for any reason not to register the Common Stock, the Company shall give written notice of such determination to each holder of Registrable Securities and, thereupon, shall be relieved of its obligation to register any Registrable Securities in connection with such registration (but not from its obligation to pay the Registration Expenses in connection therewith); (ii) if a registration requested pursuant to this Section 2 shall involve an underwritten public offering, any holder of Registrable Securities requesting to be included in such registration may elect, in writing at least 25 days prior to the effective date of the Registration Statement filed in connection with such registration, not to register such securities in connection with such registration; and (iii) if, at any time after the 180-day or shorter period specified in Section 2(b), the sale of the securities has not been completed, the Company may withdraw from the registration on a pro rata basis (based on the number of Registrable Securities requested by each holder of Registrable Securities to be so registered) the Registrable Securities which the Company has been requested to register and which have not been sold. Notwithstanding the foregoing, in connection only with the initial registered public offering of the Common Stock, which offering is a primary offering, no Registrable Securities shall be included in such registration without the prior written consent of the holders of a majority of the Vectura Registrable Securities. (b) Priority in Incidental Registrations. If a registration ------------------------------------ pursuant to Section 2(a) involves an underwritten offering and the managing underwriter advises the -4- Company in writing that, in its opinion, the total number of shares of Common Stock to be included in such registration, including the Registrable Securities requested to be included pursuant to this Section 2, exceeds the maximum number of shares of Common Stock specified by the managing underwriter that may be distributed without adversely affecting the price, timing or distribution of such shares of Common Stock, then the Company shall include in such registration only such maximum number of Registrable Securities which, in the reasonable opinion of such underwriter or underwriters, can be sold in the following order of priority: (i) first, all of the shares of Common Stock that the Company proposes to sell for its own account, if any; (ii) second, all of the shares of Common Stock being registered by holder(s) of Registrable Securities pursuant to a Demand Registration; and (iii) third, the Registrable Securities of the holder(s) of Registrable Securities requested to be included in such Incidental Registration. To the extent that shares of Common Stock to be included in the Incidental Registration must be allocated among the holders(s) of Registrable Securities pursuant to clause (iii) above, such shares shall be allocated pro rata among the holders(s) of Registrable Securities based on the number of shares of Common Stock that such holders(s) of Registrable Securities shall have requested to be included therein. Notwithstanding the foregoing, if an Incidental Registration is an underwritten offering, the managing underwriter or underwriters may select shares for inclusion, or exclude shares completely, in such Incidental Registration on a basis other than a pro rata basis if, in the reasonable opinion of such underwriter or underwriters, selection on such other basis, or inclusion of such shares, would be material to the success of the offering. (c) Selection of Underwriters. If any Incidental Registration is ------------------------- an underwritten offering, the investment banker(s) and manager(s) for the offering will be selected by the Company. (d) Expenses. The Company will pay all Registration Expenses in -------- connection with any registration of Registrable Securities requested pursuant to this Section 2. (e) Liability for Delay. The Company shall not be held responsible ------------------- for any delay in the filing or processing of a Registration Statement which includes any Registrable Securities due to requests by holders of Registrable Securities pursuant to this Section 2 nor for any delay in requesting the effectiveness of such Registration Statement. (f) Participation in Underwritten Registrations. No holder of ------------------------------------------- Registrable Securities may participate in any underwritten registration hereunder unless such holder (i) agrees to sell his or its Common Stock on the basis provided in any underwriting arrangements approved by the persons who have selected the underwriter and (ii) accurately completes in a timely manner and executes all questionnaires, powers of attorney, indemnification agreements, underwriting agreements and other documents customarily required under the terms of such underwriting arrangements. 3.

Within 10 days after receipt of the Demand Registration Request, the Company will serve written notice of such Demand Registration Request to all holders of Registrable Securities and, subject to paragraph (b) below, the Company will include in such registration all Registrable Securities of such holders with respect to which the Company has received written requests for inclusion therein from such holders within 15 business days after duly given to the applicable holder of the notice from the Company. All requests made pursuant to this paragraph 4(a) will specify the aggregate number of the Registrable Securities to be registered and will also specify the intended methods of disposition thereof. (b) Priority in Demand Registrations. The Company will not include -------------------------------- in any Demand Registration any securities (other than Company Registrable Securities) which are not Registrable Securities without the prior written consent of at least a majority of the Vectura Registrable Securities included in such registration. If any of the Registrable Securities proposed to be registered pursuant to a Demand Registration are to be sold in a firm commitment underwritten offering and the managing underwriter or underwriters of a Demand Registration advise the Company and the holders of such Registrable Securities in writing that in its or their reasonable opinion the number of shares of Common Stock proposed to be sold in such Demand Registration exceeds the maximum number of shares specified by the managing underwriter that may be distributed without adversely affecting the price, timing or distribution of the Common Stock, the Company shall include in such registration only such maximum number of Registrable Securities which, in the reasonable opinion of such underwriter or underwriters can be sold in the following order of priority: (i) first, the number of Vectura Registrable Securities requested to be included in such registration, pro rata if necessary; (ii) second, the number of Company Registrable Securities requested to be included in such registration, if any; (iii) third, all Other Registrable Securities requested to be included in such registration, pro rata if necessary; (iv) fourth, all other securities requested to be included in such registration pursuant to "demand registration" rights granted to other Persons, provided that such rights will have been granted only as permitted by this Agreement; and (v) fifth, shares of Common Stock held by other holders requested to be included in such registration, pro rata if necessary. (c) Selection of Underwriters. In the case of a Demand ------------------------- Registration for an underwritten offering, the holders of a majority of the Vectura Registrable Securities to be included in such Demand Registration will have the right to select the investment banker(s) and manager(s) to administer the offering, which investment banker(s) and manager(s) will be nationally recognized, subject to the Company's approval which will not be unreasonably withheld. (d) Expenses. The Company will pay all Registration Expenses in -------- connection with any registration of Registrable Securities requested pursuant to this Section 3. -6- (e) Other Registration Rights.

The Company hereby agrees ------------------------------ to indemnify and hold harmless each holder of Registrable Securities which shall have been registered under the Securities Act, and such holder's officers, directors and agents and each -10- other Person, if any, who controls such holder within the meaning of the Securities Act and each other Person (including underwriters) who or which participates in the offering of such Registrable Securities against any losses, claims, damages, liabilities, reasonable attorneys' fees, costs or expenses (collectively, the "Damages"), joint or several, to which such holder or ------- controlling Person or participating Person may become subject under the Securities Act or otherwise, insofar as such Damages (or proceedings in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact made by the Company or its agents contained in any Registration Statement under which such Registrable Securities are registered under the Securities Act, in any preliminary Prospectus or final Prospectus contained therein, or in any amendment or supplement thereof, or arise out of or are based upon 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, and will reimburse such holder of Registrable Securities or such controlling Person or participating Person in connection with investigating or defending any such Damages or proceeding; provided, however, that the Company will not be liable in any such case to the extent that any such Damages arise out of or are based upon (i) an untrue statement or alleged untrue statement or omission or alleged omission made in such Registration Statement, said preliminary or final Prospectus or said amendment or supplement in reliance upon and in conformity with written information furnished to the Company by such holder or such controlling or participating Person, as the case may be, specifically for use in the preparation thereof; or (ii) an untrue statement or alleged untrue statement, omission or alleged omission in a Prospectus if such untrue statement or alleged untrue statement, omission or alleged omission is corrected in an amendment or supplement to the Prospectus which amendment or supplement is delivered to such holder in a timely manner and such holder thereafter fails to deliver such Prospectus as so amended or supplemented prior to or concurrently with the sale of such Registrable Securities to the Person asserting such Damages. (b) Indemnification by the Holders of Registrable Securities -------------------------------------------------------- Which Are Registered. It shall be a condition of the Company's obligations under - -------------------- this Agreement to effect any registration under the Securities Act that there shall have been delivered to the Company an agreement or agreements duly executed by each holder of Registrable Securities to be so registered, whereby such holder agrees to indemnify and hold harmless the Company, its directors, officers and agents and each other Person, if any, which controls the Company within the meaning of the Securities Act against any Damages, joint or several, to which the Company, or such other Person or such Person controlling the Company may become subject under the Securities Act or otherwise, but only to the extent that such Damages (or proceedings in respect thereof) arise out of or are based upon any untrue statements or alleged untrue statement of any material fact contained, on the effective date thereof, in any Registration Statement under which such Registrable Securities are registered under the Securities Act, in any preliminary Prospectus or final Prospectus contained therein or in any amendment or supplement thereto, or arise out of or are based upon 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, which, in each such case, has been made in or omitted from such Registration Statement, said preliminary or final Prospectus or said amendment or supplement in reliance upon, and in conformity with, written information furnished to the Company by such holder of Registrable Securities specifically for use in the preparation thereof. The Company shall be entitled to receive indemnities from -11- underwriters, selling brokers, dealer managers and similar securities industry professionals participating in the distribution, to the same extent as provided above, with respect to information furnished in writing by such Persons specifically for inclusion in any Prospectus or Registration Statement. (c) Conduct of Indemnification Proceedings. Any Person -------------------------------------- entitled to indemnification hereunder shall (i) give prompt written notice to the indemnifying party of the commencement of any action or proceeding involving a claim referred to in the preceding paragraphs of this Section 5; and (ii) unless the indemnified party has been advised by its counsel that a conflict of interest exists between such indemnified and indemnifying parties under applicable standards of professional responsibility, with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. Whether or not such defense is assumed by the indemnifying party, the indemnifying party will not be subject to any liability for any settlement made without its consent (but such consent will not be unreasonably withheld). No indemnifying party will consent to the entry of any judgment or enter into any settlement (i) that does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect of such claim or litigation and (ii) except for judgments or settlements calling for the payment of money only, without the consent of the indemnified party (which consent will not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the defense of the 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 such indemnified parties with respect to such claim, in which event the indemnifying party shall be obligated to pay the fees and expenses of such additional counsel or counsels. (d) Contribution. If for any reason the indemnification ------------ provided for in the preceding Sections 6(a) or 6(b) is unavailable to an indemnified party in respect of any Damages referred to therein, the indemnifying party shall contribute to the amount paid or payable by the indemnified party as a result of such Damages in such proportion as is appropriate to reflect not only the relative benefits received by the indemnified party and the indemnifying party, but also the relative fault of the indemnified party and the indemnifying party, as well as any other relevant equitable considerations. The relative fault of such indemnifying party and indemnified parties shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, has been made by, or relates to information supplied by, such indemnifying party or indemnified parties, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such action; provided, however, that in no event shall the liability of any selling holder of Registrable Securities hereunder be greater in amount than the difference between the dollar amount of the proceeds received by such holder upon the sale of the Registrable Securities giving rise to such contribution obligation and all amounts previously contributed by such holder with respect to such Damages. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of fraudulent misrepresentation. -12- (e) The indemnification provided for under this Agreement will remain in full force and effect regardless of any investigation made by or on behalf of any indemnified party or any officer, director or controlling Person of such indemnified party and will survive the transfer of securities.
