CERTAIN TRANSACTIONS The former holders of our Series B, C and D preferred stock, which include Warburg, Pincus Ventures, our largest stockholder, are entitled to registration rights with respect to the common stock issued upon conversion of the Series B, C or D preferred stock. In connection with the issuance of Series B preferred stock and warrants to purchase Series C preferred stock, we entered into an agreement that requires us, as long as Warburg, Pincus Ventures owns at least 10% or 20% of the outstanding common stock, to nominate and use our best efforts to elect one or two individuals, respectively, designated by Warburg, Pincus Ventures for election to the Board or Directors. In addition, Warburg, Pincus Ventures has agreed that it will use its best efforts to vote a sufficient number of its shares to elect one individual nominated by LF SL Holding LLC as long as LF SL Holding LLC continues to own at least fifty percent of the 555,555 shares it acquired in January 1999. Under our license with The Regents of the University of California, we are obligated to make license-issue fee payments, royalty payments, milestone payments and other payments to The Regents in exchange for a license to commercially develop and sell products that make use of rights under patent applications filed by Drs. Tallal, Merzenich, Jenkins and Miller, among others, and subsequently assigned to The Regents and Rutgers, the State University of New Jersey. Four US patents issuing from these applications were granted by the United States Patent and Trademark Office and several additional applications are pending. Drs. Tallal and Merzenich are members of our Board of Directors, and Drs. Jenkins and Miller are senior vice presidents with us. During 2001, we expensed an aggregate of approximately $650,000 for royalty and milestone payments under the license. In 2002, and for each year thereafter during the term of the license, the minimum royalty payment will be $150,000. Pursuant to the patent policies of The Regents and Rutgers, as well as understandings between inventors affiliated with each university, each university distributes to those inventors affiliated with the university, on an annual basis, a portion of the payments received from us. In 2001, the inventors received the following payments from their universities: Dr. Merzenich: $117,780; Dr. Tallal: $80,004; Dr. Jenkins: $83,428; and Dr. Miller: approximately $30,000. The amount of any future university distributions to the inventors are indeterminable at this time because these figures are tied to our future performance; however, we estimate that less than 1% of product sales during the term of the license will be payable by the universities to each inventor. We negotiated the license on an arms-length basis, without involvement by the inventors. In April 2001, the Company made loans in an aggregate principal amount of $3,114,383 to Ms. Bolton, Dr. Miller, Mr. Mattson, and Mr. Mills for the purpose of assisting these executive officers in paying substantial income tax liabilities resulting from alternative minimum tax imposed on their exercise of Company stock options in 2000. At March 28, 2002, the aggregate amounts of such indebtedness for principal and accrued interest were: Ms. Bolton: $1,466,663; Dr. Miller: $1,519,043; Mr. Mattson: $247,237; and Mr. Mills: $29,745. Each loan is a full recourse loan, initially secured by a number of shares of the Company’s stock held by the officer equal to the lesser of (1) the principal amount of the loan divided by the average closing price of the Company’s stock for the 30 trading days preceding January 3, 2001, which is $4.4875; or (2) the total amount of Company stock held by the borrowing officer on the date of the note evidencing the loan. Each officer has the right to withdraw shares from the security interest to the extent that the fair market value of the collateral pledged exceeds 120% of the principal, but no officer has the obligation to pledge additional shares or to return withdrawn shares if the value of the collateral pledged falls below the loan amount. The number of shares initially and currently pledged by each officer is: Ms. Bolton, 260,785 shares; Mr. Miller, 323,120 shares; Mr. Mattson, 52,591 shares, and Mr. Mills, 6,325 shares. The loans bear interest at a rate of 4.94%. All principal and accrued interest are due December 31, 2005. The Company’s obligation to make these loans was conditioned on the initial closing of the line of credit facility described below. In March 2001, we entered into a $15 million unsecured revolving line of credit with Fleet National Bank. WPV, Inc., an affiliate of Warburg, Pincus Ventures, a substantial stockholder of the Company, provided an unlimited guaranty for the facility. In consideration of the guaranty, we agreed to reimburse the Warburg affiliate for any amounts it is required to pay in satisfaction of the loan and granted the Warburg affiliate a security interest in substantially all of our assets. We also issued the Warburg affiliate a warrant to purchase 1,375,000 shares of the Company’s common stock with an exercise price of $8.00. The warrant expires March 9, 2008. In connection with the transaction, the Company’s Registration Rights Agreement was further amended to include shares issuable on exercise of the warrant as Registrable Securities under that Agreement. The estimated value of the warrants is $3.6 million. In March 2002, we agreed with the Bank and the Warburg affiliate to extend the term of the line of credit from October 2002 to June 2004. 22 |
