In addition, we have attempted to contain costs and reduce cash flow requirements by renting scientific equipment and facilities, contracting with other parties to conduct certain research and development and using consultants. We expect to incur additional expenses, potentially resulting in significant losses, as we continue to pursue our research and development activities and undertake additional preclinical studies and clinical trials of compounds, which have been or may be discovered. We also expect to incur substantial expenses related to the filing, prosecution, maintenance, defense and enforcement of patent and other intellectual property claims. On June 25, 2002, we announced we were discontinuing the development of peramivir, our investigational oral influenza neuraminidase inhibitor designed to treat and prevent influenza. After terminating the development of peramivir, the Company streamlined its operations in order to conserve its resources and provide a longer timeframe in which to advance its other programs. On August 5, 2002, at the request of Dr. Charles E. Bugg, our Chairman and Chief Executive Officer and Dr. J. Claude Bennett, our President, Chief Operating Officer and Medical Director, our Compensation Committee and board of directors approved a 25% reduction in their salaries, effective August 1, 2002. In the event of any change of control of the Company, any cumulative salary reductions up to the date of the change of control would become due and payable to them. The aggregate monthly amount of the reduction was $14,677. The Company invests its excess cash principally in U.S. marketable securities from a diversified portfolio of institutions with strong credit ratings and in U.S. government and agency bills and notes, and by policy, limits the amount of credit exposure at any one institution. These investments are generally not collateralized and mature within three years. The Company has not realized any losses from such investments. In addition, at March 31, 2003, approximately $6.7 million was invested in the Merrill Lynch Premier Institutional Fund, which invests primarily in commercial paper, U.S. government and agency bills and notes, corporate notes, certificates of deposit and time deposits. The Merrill Lynch Premier Institutional Fund is not insured. At March 31, 2003, our cash, cash equivalents and securities held-to-maturity were $33.5 million, a decrease of $2.7 million from December 31, 2002, principally due to the funding of current operations. We have financed some of our equipment purchases with lease lines of credit. We currently have a $500,000 general line of credit with our bank, secured by a pledge of $600,000 in marketable securities. There was nothing drawn against this line as of March 31, 2003. In July 2000, we renegotiated our lease for our current facilities, which will expire on June 30, 2010. We have an option to renew the lease for an additional five years at the current market rate in effect on June 30, 2010 and a one-time option to terminate the lease on June 30, 2008 for a termination fee of approximately $124,000. The lease, as amended effective July 1, 2001 for an additional 7,200 square feet, requires us to pay monthly rent starting at $33,145 per month in July 2001 and escalating annually to a minimum of $47,437 per month in the final year, plus our pro rata share of operating expenses and real estate taxes in excess of base year amounts. As part of the lease, we have deposited a U.S. Treasury security in escrow for the payment of rent and performance of other obligations specified in the lease. This pledged amount is currently $455,000, which will be decreased by $65,000 annually throughout the term of the lease. During 2000, we renovated our facilities to gain additional laboratory space, update our existing laboratories, and add a small good manufacturing practices (GMP) clean room. In addition, we updated our general office facility to provide for growth and efficiencies. The total cost of these changes, including furniture and laboratory equipment, was approximately $2.7 million. This phase of renovation was completed in December 2000. Another phase of renovation was completed in February 2002 for approximately $2.6 million to add two chemistry laboratories and purchase additional equipment. Currently, there are no plans for additional renovations. As a result of the reduction in our staff during July 2002, we have approximately 14,000 square feet of excess space available for sublease. Of this, about 7,200 square feet will be subleased by May 1, 2003.
