EXHIBIT 99.1 EDG CAPITAL, INC. CHANGES NAME TO ISOTOPE SOLUTIONS GROUP, INC. (GARDEN CITY, NY --- NOVEMBER 20, 2001) --- EDG Capital, Inc. (OTCBB: ISTP), a developer of nuclear pharmaceuticals for therapeutic use in the treatment of cancer, announced today that on November 14, 2001, its shareholders approved the change of its corporate name to Isotope Solutions Group, Inc. The change of name was accomplished through the approval at a special meeting of shareholders of an amended and restated certificate of incorporation. The amended and restated certificate of incorporation also effected a number of other important changes meant to bring the certificate of incorporation up to date, including the authorization of a class of undesignated preferred stock and the adoption of a provision permitting the shareholders to act by less than unanimous written consent. "Our new corporate name, Isotope Solutions Group, Inc., and our new trading symbol, ISTP, more accurately symbolize our mission as a biopharmaceutical development company," said Jack Schwartzberg, Chief Executive Officer, President and Chairman. Isotope Solutions Group, Inc.'s shareholders also approved at the special meeting an increase in the shares of common stock that may be awarded under the corporation's 2000 Long-Term Incentive Plan to 2,500,000 shares, as well as certain proposed payments and/or property transfers to be made pursuant to the employment agreements between Isotope Solutions Group and each of Jack Schwartzberg and Shraga David Aranoff, Vice President, Chief Operating Officer and Treasurer, the reimbursement and termination provisions of the option agreements between Isotope Solutions Group and each of Jack Schwartzberg and Shraga David Aranoff, and the vesting provisions of the 2000 Long-Term Incentive Plan for purposes of excluding such payments and/or property transfers from the "parachute payment" provisions of Sections 280G and 4999 of the Internal Revenue Code of 1986. Approval of these proposed payments and/or property transfers may enable the corporation to deduct these payments and property transfers, which consist principally of severance pay and the acceleration of options, from its taxes as compensation expense in the event of a change in control of the corporation. The corporation is not presently aware of any proposed or contemplated change of control of the corporation. ABOUT ISOTOPE SOLUTIONS GROUP, INC.
