SciClone shall have no responsibility for payment of any costs or other obligations arising prior to the Effective Date with respect to the Clinical Trials. The parties will use their best efforts to come to a mutual agreement with respect to the allocation of any Clinical Trial expenses which are fairly applicable and allocable to time periods both before and after the Effective Date. 4.7 Verification; Refund of Consideration.

If the Verifications are not provided to SciClone's reasonable satisfaction and the Closing Items are not completed, such that this Agreement is terminated, then Sclavo shall refund to SciClone (i) the US$100,000 paid pursuant to Section 3.1(a) hereof, and (ii) the 200 million lire paid pursuant to the AIC Purchase and Sale Agreement, and (iii) any other part of the Cash Price or Shares given by SciClone to Sclavo pursuant to this Agreement. 4.8 Sclavo Affiliates.

(a) Promptly following the issuance and delivery of the shares to Sclavo (or a Permitted Nominee), SciClone shall register the sale of said Shares by Sclavo (or a Permitted Nominee) (which for purposes of this Section 5.2 shall mean and include any and all other persons or entities who or which may hold any of the Shares by permitted private transfer from Sclavo) on Form S-3 (the "Registration") in accordance with applicable rules of the SEC pursuant to the Securities Act of 1933, as amended (the "Securities Act"), or any similar United States federal statute and the rules and regulations of the SEC thereunder, all as the same shall be in effect at the time of the registration, and on all of the terms and conditions of this Section 5.2. SciClone shall keep the Registration in effect for a period of one year from the date of the issuance of the Shares to Sclavo so that Sclavo is able to resell all of the Shares it holds without volume restriction on the public market in the United States pursuant to the Registration and/or pursuant to SEC Rule 144 pursuant to the Securities Act.

(e) With a view to making available the benefits of certain rules and regulations of the SEC which may at any time permit the sale of the Shares to the public without registration, SciClone agrees to use its reasonable best efforts to: (i) Make and keep public information available, as those terms are understood and defined in Rule 144 under the Securities Act, for at least the next two years after the Effective Date; (ii) File with the SEC in a timely manner all reports and other documents required of SciClone under the Securities Act and the Exchange Act; and (iii) Furnish to Sclavo forthwith upon request a written statement by SciClone as to its compliance with the reporting requirements of Rule 144, and of the Securities Act and the Exchange Act, a copy of the most recent annual or quarterly report of SciClone, and such other reports and documents of SciClone and other information in the possession of or reasonably obtainable by SciClone as Sclavo may reasonably request in availing itself of any rule or regulation of the SEC allowing Sclavo to sell any of the Shares without registration. 5.3 Indemnification Regarding Share Registration. (a) SciClone agrees to indemnify and hold harmless Sclavo, its officers, directors, agents and employees and each Person, if any, who control any such Person within the meaning of either Section 15 of the Securities Act, or Section 20 of the Exchange Act (a "Control Person"), against all Damages caused by, arising out of, or based upon (i) any failure of SciClone to comply with any and all securities laws, rules or regulations, (ii) any breach by SciClone of its obligations under this Agreement, or (iii) any untrue or alleged untrue statement of material fact contained in the Registration Statement, any related prospectus or preliminary prospectus or any amendment thereof or supplement thereto, or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as any such untrue statement or omission was caused by or contained in any information furnished in writing to SciClone by Sclavo expressly for use therein or by Sclavo's failure to deliver a copy of a current prospectus (as amended or supplemented) after SciClone has furnished Sclavo with a sufficient number of copies for such purpose. (b) Sclavo agrees to indemnify SciClone, its directors and officers and each Control Person of SciClone against all Damages resulting from any untrue or alleged untrue statement of material fact contained in the Registration Statement any related prospectus or preliminary prospectus, or any amendment thereof or supplement thereto, or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is -12- 14 contained in any information or affidavit so furnished in writing by Sclavo expressly for use therein. (c) Any Person entitled to indemnification hereunder shall (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 Person's reasonable judgment a conflict of interest between such indemnified Person and indemnifying party exists with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified Person. If such defense is assumed, the indemnifying party will not be subject to any liability for any consent to the entry of any judgment or any settlement made by the indemnified Person without its consent (but such consent will not be unreasonably withheld). 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 (other than local counsel, as necessary) with respect to such claim for all indemnified Persons, unless in the reasonable judgment of any indemnified Person a conflict of interest exists between such indemnified Person and any other indemnified Person with respect to such claim. The indemnifying party shall not, without the prior written consent of the indemnified Person, effect any settlement or compromise of any pending or threatened proceeding in respect of which such indemnified Person is or could have been a party, and indemnity could have been sought hereunder by such indemnified Person, unless such settlement (i) includes an unconditional written release of such indemnified Person, in form and substance reasonably satisfactory to such indemnified Person, from all liability on the claims that are the subject matter of such settlement, (ii) does not include any statement as to an admission of fault, culpability or failure to act by or on behalf of any indemnified Person, and (iii) the sole relief provided consists of monetary damages that are paid in full by the indemnifying party. (d) Contribution. (i) To the extent that the indemnification provided for in this Section 5.3 is for any reason unavailable to, or insufficient to hold harmless, an indemnified Person in respect of any losses, claims, damages or liabilities, then the indemnifying party, in lieu of indemnifying such indemnified person hereunder and in order to provide for just and equitable contribution, shall contribute to the amount paid or payable by such indemnified Person as a result of such losses, claims, damages or liabilities in such proportion as is appropriate to reflect the relative fault of indemnifying party on the one hand and the indemnified Person on the other hand in connection with the statements or omissions or alleged statements or omissions that resulted in such losses, claims, damages or liabilities (or actions in respect thereof). The relative fault of the indemnifying party and the indemnified Person shall be determined by reference to, among other things, whether the untrue statement or a material fact or the omission or alleged omission to state a material fact relates to information supplied by SciClone on the one hand or Sclavo on the other, their relative intent, knowledge, access to information, and opportunity to correct or prevent such statement or omission, and any other equitable considerations appropriate in the circumstances. -13- 15 (ii) The parties agree that it would not be just and equitable if contribution pursuant to this Section 5.3 were determined by any method of allocation that does not take account of the equitable considerations referred to in paragraph 5.3(d)(i). The amount paid or payable by an indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph 5.3(d)(i) shall include all reasonable legal or other expenses actually incurred by such indemnified Person in connection with investigating and defending any such action or claim. 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 such fraudulent misrepresentation. (iii) The indemnity and contribution agreements contained in this Section 5.3 are in addition to any liability that an indemnifying party otherwise may have to the indemnified Person. (e) The indemnification provided for under this Section 5.3 will remain in full force and effect regardless of any investigation made by or on behalf of the indemnified Person or any officer, director or controlling person of such indemnified Person and will survive the sale or transfer of the Shares. 5.4 Share Resale Restriction. Sclavo agrees that during each of the first nine calendar months following the Registration effective date, Sclavo will not sell more than one-ninth (1/9) of the original number of Shares issued to Sclavo; provided, however, during the first month of such nine months, Sclavo may sell up to one-ninth (1/9) multiplied by the number of full months which have elapsed between the Effective Date of this Agreement and the effective date of the Registration.
