with SSI and SSD, the "Borrowers") and PNC Bank, National Association, as agent
for the "Lenders" under the Loan Agreement (in such capacity, "Agent")).

                                   BACKGROUND

                  A. The parties, together with the other Lenders identified
therein, entered into that certain Amended and Restated Credit Agreement dated
April 17, 1998 (as amended to date, the "Loan Agreement").

                  B. Lenders, through the Agent, and the Borrowers desire to
amend the Loan Agreement in the manner hereinafter set forth.

                  C. Capitalized terms that are not defined herein shall have
the meanings ascribed to them in the Loan Agreement.

                  D. Subject to compliance with all conditions specified herein,
all amendments hereinafter set forth are effective as of the date hereof unless
otherwise expressly stated herein to the contrary.

                  NOW, THEREFORE, intending to be legally bound, the parties
agree as follows:

                  1. RELEASE OF LIEN. SSI and SSD are, on the date hereof,
entering into a certain contract (the "Credit Suisse Contract") with Credit
Suisse Financial Products ("Credit Suisse") pursuant to which SSI and SSD have
agreed to deliver to Credit Suisse up to 1,387,000 shares of Tellabs Inc. (f/k/a
Coherent Communications Systems Corporation) common stock. Agent hereby releases
any and all liens on, and pledges of, the stock to be delivered pursuant to the
Credit Suisse Contract, consisting of up to 1,387,000 shares of Tellabs Inc.
common stock (hereinafter, the "Released Stock"), together with all proceeds
thereof and all cash and noncash dividends and other distributions with respect
thereto. Agent further agrees to hereafter release such additional shares of
Tellabs Inc. common stock that pursuant to the Credit Suisse Contract are to be

violations of the following provisions of the Loan Agreement by reason of the
Credit Suisse Contract and the transactions effected thereby:

prohibit the incurrence of SSI's and/or SSD's obligations to Credit Suisse;

granting by SSI and/or SSD of a security interest in or other rights to the
Released Stock;

                  C. Section 6.11, "Sale of Assets," to the extent it would
prohibit the disposition of the Released Stock.

                  3. MISCELLANEOUS.

                  A. Construction. The provisions of this Amendment shall be in
