THE REGENTS MAKE NO REPRESENTATION OR WARRANTY THAT THE LICENSED PRODUCTS OR LICENSED METHODS WILL NOT INFRINGE ANY PATENT OR OTHER PROPRIETARY RIGHT. 3. IN NO EVENT WILL THE REGENTS BE LIABLE FOR ANY INCIDENTAL, SPECIAL OR CONSEQUENTIAL DAMAGES RESULTING FROM EXERCISE OF THIS AGREEMENT OR THE USE OF THE INVENTION OR LICENSED PRODUCTS. 4. Nothing in this Agreement shall be construed as: (a) a warranty or representation by The Regents as to the validity or scope of any Regents' Patent Rights; or (b) a warranty or representation that anything made, used, sold or otherwise disposed of under any license of Regents' Patent Rights is or will be free from infringement of patents of third parties; or (c) an obligation to bring or prosecute actions or suits against third parties for patent infringement; or 1 (d) conferring by implication, estoppel or otherwise any license or rights under any patents of The Regents other than Regents' Patent Rights as defined herein, regardless of whether such patents are dominant or subordinate to Regents' Patent Rights; or (e) an obligation to furnish any know-how not provided in Regents' Patent Rights or Tangible Research Product. B. INDEMNIFICATION; INSURANCE. -------------------------- l. The LICENSEE agrees to indemnify, hold harmless and defend The Regents, their officers, employees, and agents; the sponsors of the research that lead to the Invention; and the inventors of the patents and patent application in Regents' Patent Rights and their employers against any and all claims, suits, losses, damages, costs, fees, and expenses resulting from or arising out of exercise of this Agreement. 2. The Regents shall promptly notify LICENSEE in writing of any claim or suit brought against The Regents in respect of which The Regents intend to invoke the provisions of this Article. LICENSEE will keep The Regents informed on a current basis at its defense of any claims pursuant to this Article. 3. At such time as LICENSEE commences research activities in its own facilities utilizing its own employees, LICENSEE, at its sole cost and expense, shall insure its activities in connection with the work under this Agreement and 2 obtain, keep in force and maintain insurance as follows, or an equivalent program of self insurance: Comprehensive or Commercial Form General Liability Insurance (contractual liability included) with limits as follows: (a) Each occurrence $1,000,000 (b) Products/Comprehensive Operations Aggregate $3,000,000 (c) Personal injury $1,000,000 (d) General aggregate (commercial form only) $3,000,000 It should be expressly understood, however, that the coverages and limits referred to under the above shall not in any way limit the liability of LICENSEE.

APPENDIX 4 To be revised and released within 60 days after the Effective Date DRAFT Announcement of agreement Between Glaxo and Megabios LONDON (DATE XX, 1994) -- Glaxo Holdings p.l.c. and Megabios Corp. today announced they have agreed to collaborate on the development of a gene therapy product for the prevention and treatment of cystic fibrosis. The agreement represents Glaxo's first foray into the field gene therapy. Gene therapy is any therapy in which a DNA fragment is introduced into cells to direct the production of a protein which in turn, produces a therapeutic effect. Leveraging Megabios' gene therapy program, the two corporations will collaborate on the development and commercialization of a product designed to produce a healthy protein in the cells lining the airways of cystic fibrosis patients with the hope alleviating the disease in the lungs. "The collaboration with Megabios should provide a model system for gaining knowledge, experience and expertise in this rapidly emerging approach to therapeutic treatment," said (GLAXO PERSON - ANDO?) "Glaxo has long been a leader in developing medicines to treat respiratory disease, and this collaboration gives us the opportunity to apply our expertise to the area of gene therapy, and benefit of thousands of young people around the world whose lives are threatened by this disease." (Quote from a Megabios person -- call William Brown at -Megabios, 415-434-3333 Liza is his secretary.) The gene therapy product has potential to deliver into lung cells of cystic fibrosis patients the molecular machinery to replace defective cystic fibrosis proteins. It will combine proprietary lipids and cDNA fragments which code for the cystic fibrosis transmembrane regulator protein (CFTR). Cystic fibrosis affects about 33,000 people in the United States and Canada, and about 20,000 in Europe. It is the most common lethal hereditary disease affecting Caucasian 7 populations, and occurs in about one of every 2,000 births. The average life span of a person with CF is less than 30 years. The disease results from defects in CFTR proteins that regulate the transport of salt through cell walls. The transport defect causes the mucus in the lining of the lung, pancreas and liver to accumulate and become abnormally thick and sticky, and significantly impair the organ's function. Present treatments help thin the mucus or treat infections associated with the mucous load, but don't correct the genetic flaw. Gene therapy would represent a significant advance over currently therapies. London-based Glaxo Holdings, p.l.c., is a leader in research and treatment of respiratory disease as well as gastrointestinal, central nervous system, cardiovascular and infectious diseases. Glaxo is an integrated research-based group of companies whose corporate purpose is to create, discover, develop, manufacture and market throughout the world safe, effective medicines of the highest quality which will bring benefit to patients through improved longevity and quality of life, and to society in general through economic value. Megabios Corp., located in San Carlos, Calif., is a privately-held biopharmaceutical company formed to develop and commercialize lipid-based in vivo gene therapeutics for the treatment of life-threatening disorders. The company's unique knowledge of gene delivery and expression, lipid synthesis, DNA/lipid complex formulation and multiple routes of administration is the basis for the development of new therapeutics. 8 AMENDMENT NO. 1 TO RESEARCH AND LICENSE AGREEMENT THIS AMENDMENT NO. 1 (the "Amendment") is entered into as of this 31st ---- day of May, 1996, by and between MEGABIOS CORP., a California corporation, having offices at 863A Mitten Road, Burlingame, California 94010 ("MEGABIOS") and GLAXO GROUP LIMITED, a corporation organized under the laws of England and Wales having offices at Glaxo House, Berkeley Avenue, Greenford, Middlesex, UB60NN, England ("Glaxo"), each of MEGABIOS and Glaxo being referred to herein as a "Party" and both being referred to herein as "Parties."
