The Company has agreed to provide the registration rights provided for in this Agreement as an inducement for the Holder to sell all of the capital stock of Pharmaco US to the Company pursuant to the Stock Purchase Agreement, dated February 28, 1997, by and among the Company, the Holder and Phillip Altman and Juanita Altman (the "Stock Purchase Agreement"), and to enter into other agreements contemporaneously with this Agreement. Witnesseth: The parties hereto, each intending to be legally bound and in exchange for the mutual covenants herein, agree as follows: 1. Inclusion in Offerings. If, during the period beginning the date hereof and ending 12 months from the date hereof (the "First Registration Period"), the Company or any security holder of the Company files a registration statement with the Securities and Exchange Commission to register the Company's Common Stock (a "Registration"), other than (i) a registration statement on Form S-4, (ii) a registration statement on Form S-8 or (ii) a registration statement in connection with an underwritten public offering, the Company shall ensure that all Registrable Securities shall be included in such Registration if so requested by the Holders owning such Registrable Securities; provided, however, that the Holders shall not be entitled under this Section 1 to have included in a Registration Registrable Securities with a value (as determined by the price at which such Registrable Securities are to be offered) greater than 25% of the total number of the securities registered in such Registration. 2. Demand Registrations. (a) Requests for Registration. For the period beginning immediately following the expiration of the First Registration Period and ending 12 months thereafter, the Holders may demand registration (a "Demand Registration") under the Securities Act of 1933, as amended (the "1933 Act"), of all or any part of the Registrable Securities owned by such Holders. In order to accomplish such demand, the Holder shall send written notice of the demand to the Company, and such notice shall specify the number of Registrable Securities sought to be registered. The Company shall only be required to effect one Demand Registration. (b) Priority on Demand Registrations. If a Demand Registration is underwritten and the managing underwriters advise the Company in writing that in their opinion the number of Registrable Securities requested to be included exceeds the number that can be sold in such offering, at a price reasonably related to fair value, the Company will include in such Demand Registration (i) first, the Registrable Securities requested to be included in such Demand Registration by the Holder; (ii) second, any securities that the Company desires to include on its own behalf; and (iii) third, any shares of Common Stock held by any other stockholder of the Company to whom registration is offered. (c) Selection of Underwriters. If any Demand Registration is underwritten, the selection of investment banker(s) and manager(s) and the other decisions regarding the underwriting arrangements for the offering will be made by the Company and the Holders participating in the Demand Registration. (d) Restrictions on Demand Registrations. The Company will not be obligated to effect any Demand Registration within six months after the effective date of a previous registration of securities of the Company in an underwritten offering. 3. Registration and Offering Expenses. In connection with all registrations and Offerings of Registrable Securities under this Agreement, the Company shall pay the Registration Expenses (defined below) related to the Registrable Securities of the Holders, but the Holders shall pay the Underwriting Commissions (defined below), if any, related to their Registrable Securities. 4. Holdback Agreements. The Holders shall not effect any public sale or distribution of equity securities of the Company or any securities convertible into or exchangeable or exercisable for such securities during a period prior to and after any underwritten offering is consummated (except as part of such Offering) that is determined by the underwriters of such offering. 5. Indemnification. (a) The Company shall indemnify, to the extent permitted by law, each Holder, its officers and directors, and each person who controls such holder (within the meaning of the 1933 Act or the Securities Exchange Act of 1934, as amended ("the 1934 Act")) (each, a "Holder Indemnitee"), against all losses, claims, damages, liabilities and expenses arising out of or resulting from any untrue or alleged untrue statement of material fact contained in any registration statement, prospectus or preliminary prospectus or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading except insofar as the same are caused by or contained in any information furnished in writing to the Company by such Holder Indemnitee, acting in its capacity as a stockholder (or an officer, director or controller of a stockholder) expressly for use therein or by any such Holder Indemnitee's failure to deliver a copy of the registration statement or prospectus or any amendments or supplements thereto after the Company has furnished such Holder Indemnitee with a sufficient number of copies of the same. (b) In connection with any registration statement in which a Holder is participating, each such Holder shall furnish to the Company in writing such information as is reasonably requested by the Company for use in any such registration statement or prospectus and shall indemnify, to the extent permitted by law, the Company, its directors and officers and each person who controls the Company (within the meaning of the 1933 Act or the 1934 Act) against any losses, claims, damages, liabilities and expenses resulting from any untrue or alleged untrue statement of material fact or any omission or alleged omission of a material fact required to be stated in the registration statement or prospectus or any amendment thereof or supplement thereto or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is contained in information so furnished in writing by such Holder (i) specifically for use in preparing the registration statement and (ii) in such Holder's capacity as a stockholder of the Company, and not in such Holder s capacity as an officer, director or employee of the Company. (c) Any person entitled to indemnification hereunder shall (i) give prompt 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 and indemnifying parties 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, the indemnifying party shall not be subject to any liability for any settlement made without its consent (but such consent will not be unreasonably withheld). An indemnifying party who is not entitled, or elects not, to assume the defense of a claim shall 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. 6.
