The consortium leader has already assumed an unlimited-term payment guaranty in the amount of DM 7,700,000.00 on 11/15/00 in connection with the general contractor contract concluded on 10/5/00 between the Borrower and the firm of Walter Bau AG, Dusseldorf, and has assumed an unlimited-term performance suretyship to the City of Hilden in the amount of DM 250,000.00 on 3/26/01 in connection with the yet-to-be-concluded public agreement (see Appendix 4).

Effective at that point in time, they shall be entitled to guaranty commissions on a pro rata basis according to their percentage shares. The consortium leader shall notify the Borrower, SSK and IKB appropriately. (S) 3 Interest and guaranty commission 3.1 Interest rate guarantee Interest rate guarantees may be agreed upon for terms of one to three months for the individual cash drawings. If the parties have not concluded a different agreement within five days before the expiration of an interest rate guarantee, the same term shall form the basis for the next interest rate guarantee period. 3.2 Interest rate and due date The interest rate p.a. for drawings shall be determined in EUR according to EURIBOR for the respective term, plus a margin of 1.2 percent p.a. EURIBOR is the interest rate as set on the second Frankfurt banking business day prior to the beginning of an interest rate guarantee for EUR credits of the respective term in accordance with the screen publication of the Dow Jones Telerate Information Service (Bridge Telerate page 248) for 11:00 a.m. Brussels time. If a EURIBOR interest rate is not published there on the relevant date, EURIBOR shall be deemed to be based on the arithmetic mean (rounded to three decimal points) of the interest rates at which cash deposits are offered to the consortium leader by two leading internationally respected banks in Frankfurt at approximately 11:00 a.m. If, by separate agreement, the term is not exactly 1, 2 or 3 months--in order to consolidate blocks effective at the beginning of the next interest rate guarantee period-- but rather a period of time which lies in between, the EURIBOR shall be determined by means of linear interpolation from the neighboring EURIBOR rates. In this connection, the Interpolated Rate is calculated as follows: [see source for equation] r\\n\\ = interpolated EURIBOR r\\n - 1\\ = preceding neighboring EURIBOR rate r\\n + 1\\ = following neighboring EURIBOR rate t\\n\\ = point in time of the interpolated EURIBOR t\\n - 1\\ = point in time of the preceding neighboring EURIBOR t\\n + 1\\ = point in time of the following neighboring EURIBOR Interest shall be calculated on the basis of actually elapsed days divided by 360 (365/360). Interest shall be due at the end of each interest period. The consortium leader shall notify the Borrower concerning the beginning and end and the determined interest for the interest rate guarantee for the respective drawings. 3.3 Default interest In the event of default, the Borrower shall owe the consortium banks default interest in the amount of 5 percent p.a. above the base interest rate according to (S) 1 of the Discount Rate Transition Act of June 9, 1998. 3.4 Guaranty commission The guaranty commission shall be 1.5 percent p.a. The consortium leader shall receive EUR 75.00 for the issuance of a guaranty document. A guaranty commission in the amount of 1.2 percent p.a. shall be charged for the guaranty for DM 9,900,000.00 [--] dated 6/19/01 [--] for the benefit of the Qiagen Hilden "Produktionsgebaude P 1" [production building P 1] [--] joint venture. (S) 4 Term and repayment The (maximum) term of the credit shall be two years, calculated from the date of the conclusion of the contract. The last drawing may not extend beyond the end of the term. The Borrower may terminate individual drawings, including termination of partial sums, upon notice of one month effective at the end of the respective interest period. In the case of termination of partial sums, it shall not be possible to fall below the minimum sum for individual drawings. Terminated sums cannot be drawn again. The Borrower shall have a right of termination no earlier than six months after the signing of this contract. The consortium banks are willing to accept repayment on a one-time basis during interest periods and prior to the due date in the event that the Borrower raises funds by means of the public issuance of a bond or similar instruments. It shall be a prerequisite in this regard that the Borrower reimburse the consortium banks for possible damages due to the worsening of interest (reinvestment damage) for the period until the end of the current interest period and lost profit (interest margin damage) up to the point in time at which ordinary termination would be possible and pay a processing fee in the amount of EUR 15,000.00 for each of the consortium banks. The Borrower shall announce the repayment, and said announcement must be received by the consortium leader one week before the date of the intended repayment. If the announcement is not made at least five banking business days before the expiration of an interest rate guarantee for a drawing or no deviating agreements are concluded, an extension of the interest rate guarantee shall take place for the respective drawing in accordance with section 3.1 sentence 2. Otherwise, the interest for the period from the expiration of the interest rate guarantee for the drawing until repayment is calculated on the basis of the EURO overnight rate ("Euro Overnight Index Average Rate"--abbreviated as "EONIA")--plus a margin of 1.2 percent p.a. The EONIA shall be the quote of the Dow Jones Telerate Information Service (page 247) on the basis of the average rate calculated by the European Central Bank at 7:00 p.m. (Brussels time). The consortium banks may jointly terminate individual drawings upon notice of 6 months effective at the end of the respective interest period.
