Effective January 1, 2004, this Amendment is made on the thirty-first day of

        WHEREAS, the Administrative Committee approved a change with regards to
loan procedures to simplify administration of the Tellabs Advantage Program
(“Plan”), and pursuant to Article Eleven and in connection with respect thereto;

        NOW, THEREFORE, the sections of the Plan set forth below are amended as
follows, but all other sections of the Plan shall remain in full force and
effect.

1.     Section 7.11(a) is amended and restated as follows:

(a)         Upon the submission by the Participant of a written loan application
form as prescribed by the Administrative Committee, or any other process
approved by the Administrative Committee, a Participant shall be able to apply
for a loan. The funds for such loan may only come from a Participant’s After-Tax
Account, Before-Tax Account, Rollover Account, Coherent Before-Tax Account,
Coherent Employer Account, Coherent Rollover Account, Salix Before-Tax Account,
Salix Employer Account, Salix Rollover Account, Profit Sharing Account
attributable to pre-1992 Profit Sharing Contributions, and Ocular Account.
Participants shall not be allowed to obtain a loan from the Accounts comprised
of Company contributions, with the exception of the pre-1992 Profit Sharing
Contributions. If the Administrative Committee reasonably believes that the
Participant either does not intend to repay the loan or lacks proper financial
ability to repay the loan, it shall not grant such a loan. A Participant shall
have no more than three loans outstanding at any time.

2.     Section 7.11(c) is amended and restated as follows:

(c)         The amount of any loan shall not be less than $1,000 unless, in the
event that a Participant demonstrates financial hardship, the Administrative
Committee, in its sole discretion, approves a loan in an amount less than
$1,000. The maximum amount of a Participant’s loan shall not exceed the lesser
of: (1) 50%of the Participant’s Before-Tax Account plus 100% of the funds
available in a Participant’s After-Tax Account, Rollover Account, Coherent
Before-Tax Account, Coherent Employer Account, Coherent Rollover Account, Salix
Before-Tax Account, Salix Employer Account, Salix Rollover Account, Profit
Sharing Account attributable to pre-1992 Profit Sharing Contributions, Ocular

Fund on the date on which such loan is made or modified.

and the terms as stated in this Amendment, the terms stated in this Amendment
shall prevail.
