PREVENTX(R) FOR IMMEDIATE RELEASE INVESTOR CONTACT: Steve Phillips Edward Howard & Co. (216) 781-2400 MEDIA CONTACT: Diana Lueptow or Steve Phillips Edward Howard & Co. (216) 781-2400 EMPYREAN BIOSCIENCE AND INTERNATIONAL BIOSCIENCE FORM JOINT VENTURE COMPANIES SETTLE ALL OUTSTANDING LEGAL ISSUES CLEVELAND, August 10, 2000 - Empyrean Bioscience Inc. (OTCBB: EMDG) and International Bioscience Corp. (IBC) today announced the formation of a joint venture, to manufacture, market, sell and distribute innovative personal care products throughout the world. The products will be based upon proprietary formulations licensed from IBC designed to prevent the spread of infectious diseases. The creation of this 50/50 joint venture is part of an overall settlement wherein the two companies have resolved all outstanding legal issues between them. The joint venture will operate under a business plan developed jointly by Empyrean and IBC. A board of directors representing both companies will provide oversight, and a team comprising marketing personnel from Empyrean and scientific personnel from IBC will coordinate new product development. Under the agreement, Empyrean will retain full and exclusive rights to sell, market and distribute a wide range of products in the United States based upon IBC formulations. Empyrean will license all Preventx(R) trademarks and logos to IBC and the joint venture. Empyrean will pay IBC a five percent royalty on net sales within the United States. -more- IBC will be granted full and exclusive rights to sell, market and distribute all products using IBC formulations in Brazil. IBC will retain the right, title and interest in all product formulations and will license the GEDA(R) trademarks to both Empyrean and the joint venture. IBC will pay Empyrean a five percent royalty on net sales within Brazil. In exchange for the issuance of 5,000,000 shares of Empyrean common stock, IBC will forgo the payment by Empyrean of any further minimum guaranteed royalties, which total $13,657,000 for the seven years remaining in the initial term of the existing license agreement and $46,311,000 in the first ten-year renewal term. In addition, Empyrean will grant IBC an option to purchase another 2,226,000 shares of Empyrean common stock, having a strike price of $0.83 a share and vesting based upon IBC's completion of critical strategic initiatives. As part of the agreement, IBC agreed to fund clinical trials for the microbicidal contraceptive gel, with a commitment to invest up to $10 million. The trials will be designed to fulfill all requirements for United States Food and Drug Administration approval of the product. The trials will test the efficacy and safety of the microbicidal contraceptive gel against various sexually transmitted diseases including HIV. For all markets other than the United States and Brazil, Empyrean and IBC will operate the joint venture to manufacture, market, sell and distribute products based on the IBC formulations by granting distribution rights to independent, third-party distributors, which will be qualified under requirements developed in the joint venture. "Maximizing the strengths of both companies and truly aligning our interests for the first time, the joint venture will enable us to focus our full, collective attention on realizing the potential that our products offer," said Richard C. Adamany, Empyrean's president and chief executive officer. "By combining forces, we can now aggressively bring products to market that will not only help our shareholders achieve maximum value, but can also lead the worldwide battle against infectious diseases. The joint venture is the perfect marriage of Empyrean's sales, marketing and distribution capabilities with IBC's world-class research, development and regulatory expertise." "We are particularly excited about the potential of our microbicidal contraceptive gel," continued Adamany, "which we believe will be shown to be effective against HIV and a host of other sexually transmitted diseases, and thereby become the leading product in an estimated $2 billion global market." -more- "The settlement allows IBC and Empyrean to work together with regulatory agencies toward expediting the approval of our products," said IBC's President and Chief Executive Officer, Sara Gomez de Ferro. "This cooperation is especially critical to obtain approval for our microbicidal contraceptive gel, which will begin Phase III trials in Brazil for gonorrhea, chlamydia, syphilis, herpes and Trichomonas within the next 120 days, as these trials will be conducted in accordance with USFDA guidelines. IBC has waived its guaranteed minimum royalty payments in exchange for the shares of Empyrean and the opportunity to work together to execute our joint business plan, which we anticipate will be far more profitable to our company than the royalty guarantees." "The global need for an effective microbicide to prevent the transmission of sexual diseases, including enveloped viruses such as HIV, has never been greater," said Dr. David Thornburgh, IBC's chairman. "We are anxious to begin large clinical trials which we hope will confirm the favorable results that were obtained in several pilot studies. By resolving the outstanding issues between our companies, we can now direct our attention to this important task." All pending legal actions between Empyrean and IBC will be dismissed. As part of the settlement, IBC agreed to fully indemnify Empyrean for any damages Empyrean may incur resulting from the legal actions involving Optima Holding Co. Empyrean and IBC will also join forces to resolve the claims against Optima.
