    In other business, stockholders approved an amendment to the Company's Certificate of Incorporation increasing the authorized number of shares of Common Stock and also ratified Ernst & Young, LLP, as the Company's independent public accountants for the 1999 fiscal year.
    In his presentation to stockholders, J. Thomas Parmeter, PPTI's President and Chief Executive Officer, provided an update on the Company's financial status and plans, and on the Company's preparation for clinical testing of its injectable urethral bulking agent for the treatment of female stress urinary incontinence, scheduled to begin in the 3rd Quarter of 1999.
    "Since March 31, 1999, approximately $920,000 has been raised through the exercise of the Company's publicly traded redeemable warrants and certain other private warrants. However, additional development expenditures will be required for clinical testing and product registration with the FDA," said J. Thomas Parmeter, PPTI's President and Chief Executive Officer. "Our ability to proceed is entirely dependent on identifying additional sources of working capital. We hope to raise additional funds for continuing operations through private or public offerings and collaborative agreements, and we also are continuing to pursue other alternative financing strategies."
   "Currently, we are in discussions with potential strategic partners for each of the soft tissue augmentation products, and in our redefined surgical adhesives and sealants program, we are seeking a partnering relationship for the development of a unique injectable Spinal disc repair product for the treatment of lower back pain. However, there is no assurance that we will succeed in consummating any of these fundings in the necessary time frame, or on terms favorable to the Company. If adequate funds are not available, we will have to significantly curtail our operations, and we may have to sell or license out significant portions of the Company's technology or potential products," Dr. Parmeter added.
   Protein Polymer Technologies, Inc., is a San Diego-based company focused on developing products to improve medical and surgical outcomes. From its inception in 1988, PPTI has been a pioneer in protein design and synthesis, developing an extensive portfolio of proprietary biomaterials. These genetically engineered biomaterials are high molecular weight proteins, processed into products with physical and biological characteristics tailored to specific clinical performance requirements. Targeted products include urethral bulking agents for the treatment of stress urinary incontinence, dermal augmentation products for cosmetic and reconstructive surgery, adhesive fillers for repair of Spinal discs, surgical adhesives and sealants, scaffolds for wound healing and tissue engineering, and depots for local drug delivery.
