Harman owns all of the outstanding capital stock of HAC and as a result, Harman is deemed to also beneficially own these 1,279,775 shares of Common Stock or approximately 26.0% of the Common Stock that would be outstanding after giving effect to the exercise in full of the Warrant. (b) Under SEC regulations, HAC is deemed to have sole voting and dispositive power with respect to 1,279,775 shares of Common Stock as a result of its ownership of the Warrant. HAC is a wholly owned subsidiary of Harman. As such, under SEC regulations Harman may be deemed to also have shared voting and dispositive power with respect to 1,279,775 shares of Common Stock as a result of HAC's ownership of the Warrant. (c) None. (d) Not applicable (e) Not applicable. ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER. On May 31, 2000, Systems and HAC entered into an Asset Sale Agreement (the "Asset Sale Agreement") pursuant to which Systems acquired substantially all of the assets of HAC (the "Transaction"). As consideration for the assets of HAC, HAC received $1,500,000 in cash, a $3.5 million short-term note (the "Tranche B Note"), a $5 million long-term note (the "Tranche A Note" and, together with the Tranche B Note, the "Notes") and the Warrant to purchase 1,000,000 shares of Common Stock, exercisable for $2.25 per share. The Warrant expires on May 31, 2003 and can be exercised either (i) by payment in cash, (ii) by reducing the amount of the unpaid principal on the Tranche A Note or the Tranche B Note, or (iii) by any combination of (i) and (ii). The provisions of the Warrant also provide HAC with anti-dilution protection under certain circumstances, including for stock splits, stock dividends, combinations, reclassifications and issuances of Common Stock at prices below the current trading price or the exercise price of the Warrant. As a result of certain transactions effected by CRL subsequent to the issuance of the Warrant, the aggregate number of shares of Common Stock issuable upon exercise of the Warrant increased to 1,279,775 shares, and the exercise price per share decreased to $1.7386 per share. The provisions of the Warrant further provide HAC with certain rights to cause CRL to register the shares of Common Stock issuable to HAC upon exercise of the Warrant. CRL has filed a registration statement registering the sale by HAC of the shares issuable upon exercise of the Warrant. (Page 6 of 104 Pages) Under the terms of the Asset Purchase Agreement, Systems and HAC entered into an $8,500,000 Credit Agreement (the "Credit Agreement") that governs the repayment of the Notes. In addition, CRL, Systems and HAC entered into a Guarantee and Collateral Agreement (the "Guarantee") whereby each of CRL and Systems pledged all of their respective assets, including the stock of Systems, as collateral for the repayment of the Notes. Among other things, the Guarantee provides that the cash proceeds received by CRL from any sale of debt or equity securities or sales of assets by CRL will be applied to pay amounts owed under the Notes. Between May 31, 2000 and October 31, 2001, HAC and Systems agreed to several payment extensions on the Notes. On October 1, 2001, Systems and HAC entered into an amendment to the Credit Agreement under which both Notes were amended and restated (the "Amended Credit Agreement"). Under the Amended Credit Agreement, the Notes were converted to demand notes payable on the demand of HAC or if no demand is sooner made, on the dates and in the amounts specified in the Amended Credit Agreement. Interest only payments remain payable from time to time for both Notes and are also due on demand. Additionally, under the Amended Credit Agreement, the first principal payment on the Tranche A Note of $250,000 was increased to $1,250,000 and is now due April 30, 2002, unless HAC demands payment at an earlier date. HAC acquired the Warrant (and as a result, beneficial ownership of the Common Stock issuable upon exercise of the Warrant) as consideration received in the Transaction. HAC from time to time intends to review its investment in CRL on the basis of various factors, including CRL's business, financial condition, results of operations and prospects, general economic and industry conditions, the securities markets in general and for CRL's securities in particular, as well as other developments and other investment opportunities. Based upon such review, it will take such actions in the future as it may deem appropriate in light of the circumstances existing from time to time, including but not limited to demanding payment of all or a portion of the principal and interest due under the Notes and/or exercising its rights under the Credit Agreement, as amended, the Guarantee or the Asset Sale Agreement. Depending on market and other factors, HAC may determine to dispose of some or all of the Notes and/or the Warrant. The foregoing descriptions of the Asset Sale Agreement, the Warrant, and the Guarantee are qualified in their entirety by reference to the copies of such agreements which have been filed as exhibits to this Schedule 13D.
