          are made.  The maximum number of employees of Tellabs TG to whom
          Bonus Stock Awards may be granted however is 50.

     2.2  Terms of Bonus Stock Awards

          Bonus Stock Awards shall be subject to the following terms and
          conditions.

          a)   Number of Shares and Other Terms

          The number of shares of Common Stock subject to Bonus Stock Award
          granted to any one person pursuant to this Plan shall be no
          greater than 500, subject to adjustment as provided in Section 3.3 
          hereof.

          b.   Vesting and Forfeiture

          One-half of the number of shares of Common Stock subject to a
          Bonus Stock Award shall vest and be payable on the first

                                   2

          anniversary of the Closing Date and the other half of such number 
          shall vest and be payable on the second anniversary of the
          Closing Date, in each case, subject to Section 2.3 b), if the 
          holder of such award remains continuously in the employment of
          Tellabs or Tellabs TG until such anniversary date of the Closing
          Date.  Such holder shall forfeit the unvested portion of any such
          shares if such holder does not remain continuously in the
          employment of Tellabs or Tellabs TG as specified above, except as 
          otherwise provided in Section 2.3 b) hereof.

     c.   Share Certificates

          Upon the vesting of a portion of a Bonus Stock Award pursuant to
          Section 2.2 b), 2.3 b) or 3.5, in each case subject to Tellabs or
          Tellabs TG rights to require payment of any taxes in accordance
          with Section 3.2, a certificate or certificates evidencing
          ownership of the number of shares of Common Stock so vested shall 
          be delivered to and in the name of the holder of such award.
          Notwithstanding the foregoing, in lieu of the delivery of shares
          representing all or a portion of the vested portion of a Bonus
          Stock Award, the Committee may, in its sole discretion, deliver
          to the holder cash in an amount equal to the Fair Market Value on
          the date such shares become vested equal to the vested portion of
          such award, less any applicable withholding, as required by
          Section 3.2, as the case may be.

     d.   Price

          No payment shall be required or exigible by a recipient of a
          Bonus Stock Award or Common Stock pursuant to this Plan.  Bonus 
          Stock Awards and Common Stock issued pursuant to this Plan shall
          be granted by Tellabs as consideration for a recipient's having
          decided to remain as an employee of Tellabs TG following its
          acquisition by Tellabs.

     2.3  Termination of Employment.

          for Cause, (ii) if such employment terminates by reason of the
          holder's Disability, or death, or (iii) if a holder voluntarily
          terminates his employment with Tellabs or Tellabs TG for any
          reason, the portion of such award which is not vested pursuant
          to Section 2.2(b) shall be forfeited by such holder and such
          portion shall be canceled by Tellabs.

     b.   Other Termination

          If Tellabs or Tellabs TG terminates the employment of the
          holder of a Bonus Stock Award for any reason other than Cause or
          Disability, the portion of such award which is not otherwise
          vested shall vest pursuant to Section 2.2(b) without regard to
          such termination.


                                   3


3.   GENERAL

     3.1  Amendments

          The Board may amend this Plan as it shall deem advisable,
          provided, however, that no amendment shall be made if such  
          amendment would increase the maximum number of shares of Common
          Stock available under this Plan (subject to Section 3.3).  No
          amendment may impair the rights of a holder of an outstanding  
          award without the consent of such holder.

     3.2  Tax Withholding

          Tellabs and Tellabs TG shall have the right to require, prior
          to the issuance or delivery of any shares of Common Stock or the
          payment of any cash pursuant to an award made hereunder, payment
          by the holder of such award of any federal, provincial, local or
          other taxes which may be required to be withheld or paid in
          connection with such award.  The Committee may allow shares of  
          Common Stock to be delivered or withheld having an aggregate Fair
          Market Value not in excess of the minimum amount required to be
          withheld.  Any fraction of a share of Common Stock which would be
          required to satisfy such an obligation shall be disregarded and
          the remaining amount due shall be paid in cash by the holder.

     3.3  Adjustment

          In the event of any stock split, stock dividend,
          recapitalization, reorganization, merger, consolidation,  
          combination, exchange of shares, liquidation, spin-off or other
          similar change in capitalization or event, or any distribution to
          holders of Common Stock other than a regular cash dividend, the
          number and class of securities available under this Plan, the
          number and class of securities subject to each outstanding Bonus 
          Stock Award shall be adjusted or modified accordingly, as
          determined by the Committee, which adjustment may include providing 
          for payment of an asset not constituting a security upon the
          vesting of an outstanding Bonus Stock Award.  The decision of the  
          Committee regarding any such adjustment shall be final, binding
          and conclusive.  If any such adjustment would result in a
          fractional security being (i) available under this Plan, such  
          fractional security shall be disregarded, or (ii) subject to an
          award under this Plan, Tellabs or Tellabs TG shall pay the holder
          of such award, in connection with the first vesting of such
          award, in whole or in part, occurring after such adjustment, an  
          amount in cash determined by multiplying (i) the fraction of such
          security (rounded to the nearest hundredth) by (ii) the excess,
          if any, of the Fair Market Value on the vesting date.

     3.4  Minimum Sum to be Collected

          Given that Bonus Stock Awards and Common Stock issued pursuant
          to this Plan without any payment being required or exigible, no
          minimum sum will be collected.  Bonus Stock Awards and Common
          Stock issued pursuant to this Plan shall be granted by Tellabs
          as consideration for a recipient's having decided to remain as
          an employee of Tellabs TG following its acquisition by Tellabs.

                                   4

     3.5  No Assignment

          It is a condition of this Plan, and the rights of all holders
          of Bonus Stock Awards shall be subject thereto, that no right or
          interest of any such holder shall be assignable or transferable
          in whole or in part, either directly or by operation of law or
          otherwise, including, but not by way of limitation, execution,
          levy, garnishment, attachment, pledge or bankruptcy, and no right
          or interest of any such holder under this Plan shall be liable
          for, or subject to, any obligation of any such holder, including
          claims for alimony or the support of any spouse.

     3.6  No Right of Employment

          Neither this Plan nor any award made hereunder shall confer upon
          any person any right to continued employment by Tellabs, Tellabs
          TG or any subsidiary or affiliate thereof or affect in any manner
          the right of Tellabs, Tellabs TG or any subsidiary or affiliate
          thereof to terminate the employment of any person at any time
          without liability hereunder.

     3.7  Right as Stockholder

          No person shall have any right as a stockholder of Tellabs with
          respect to any shares of Common Stock or other equity security of
          Tellabs which is subject to an award hereunder unless and until
          such person becomes a stockholder of record with respect to such
          shares of Common Stock or equity security.  Tellabs's obligation
          to deliver shares of Common Stock pursuant to this Plan shall be
          unfunded, and Tellabs shall not be obligated to set aside any of
          its assets for the purpose of satisfying its obligations
          hereunder.  The claims of holders of Bonus Stock Awards shall be  
          solely those of an unsecured creditor of Tellabs.

     3.8  Governing Law

          This Plan and each award hereunder, and all determinations made
          and actions taken pursuant hereto, to the extent not otherwise
          governed by the laws of the United States, shall be governed by
          the laws of the State of Delaware and construed in accordance
          therewith without giving effect to principles of conflicts of laws. 

     3.9  Effective Date

          This Plan shall have retroactive effect from the Closing Date
          following its approval by the Commission des valeurs mobilieres
          du Quebec.
