November 22, 1995

Mr. Allan Toomer
Senior Vice President & General Manager
Tekelec
Network Switching Division
3000 Aerial Parkway
Suite #120
Morrisville, NC 27560

Dear Allan,

                 I am very pleased to offer the following compensation program
to you as Senior Vice President and General Manager of Tekelec's Network
Switching Division ("NSD"). This package, once accepted by you, will supersede
and replace any executory portions of that agreed to in my letter to you dated
September 5, 1994 (see attached). I am proposing a longer term commitment
through 1997 from both you and Tekelec to supersede the previous arrangement. I
believe this is beneficial to both of us because of the potential the EAGLE
business offers and the contribution you can continue to make to its success.

                 1.       Your base salary will be $203,000 per annum payable
                          $7,807.69 bi-weekly effective October 1, 1995. It
                          will be reevaluated annually each year thereafter
                          based on my recommendations to the Compensation
                          Committee of the Board and subject to final Board
                          approval.

                 2.       The terms of your bonus plan for 1995 will be as
                          follows:

                          (a)     Up to * of your annual salary based on
                          achievement of 105% of NSD's business plan revenues
                          for 1995 (see attached) and operating income of * or

                          (b)     Up to * of your annual salary based on
                          achievement of 110% of NSD's business plan revenues
                          for 1995 and operating income of *.

                 Under these criteria, the aggregate amount of your bonus for
1995 will be determined as follows:

                          o       one third of the bonus will be based on
                                  achievement of the revenue objective

                          o       one third of the bonus will be based on
                                  achievement of both the revenue and operating
                                  income objectives

                          o       one third of the bonus will be based on
                                  achievement of both the revenue objectives
                                  and management objectives set forth in your
                                  1994 review and based on my recommendation to
                                  the Board.

                 The bonus plan for each year thereafter will be based on the
Tekelec Corporate Executive bonus program recommended annually by me and
approved by the Board of Directors.

                 3.       The terms of the Early Retirement Bonus Plan outlined
                          in the letter of September 5, 1994, will be amended
                          as follows and will be in lieu of the benefits you
                          are eligible to receive under the Officer Severance
                          Plan. If you elect on or after 1/1/97 and prior to
                          4/1/97 to retire, or if your employment with Tekelec
                          terminates prior to 4/1/97 as a result of your death
                          or long-term disability, then you receive the
                          following:

                                  A bonus payment equal to 130% of the sum of
                                  your then current salary plus the highest
                                  annual bonus paid to you by Tekelec in the
                                  three calendar years prior to your retirement
                                  date. At a minimum this will amount to
                                  $300,000.

                          In addition, if your employment with Tekelec
                          terminates prior to 4/1/97 as a result of your death
                          or long-term disability, then all stock options
                          granted to you prior to 9/30/95 under Tekelec's 1984
                          and 1994 Stock Option Plan which remain unvested at
                          the date of such termination would immediately vest.

                 4.       The vesting of the unvested portion of all stock
                          options granted to you prior to September 30, 1995
                          under Tekelec's 1984 and 1994 Stock Option Plan will
                          accelerate on a "first-in-first-out basis" and become
                          exercisable as follows:


                                                          
                              December 31, 1995              26,000
                              March 31, 1996                 23,000
                              June 30, 1996                  20,000
                              September 30, 1996             17,000
                              December 31, 1996              10,000
                                                             ------
                                                             96,000


                 5.       Provided a successor as General Manager of NSD has
                          been identified and approved by the Board of
                          Directors and upon the effective date of your
                          full-time retirement, then Tekelec will enter into a
                          consulting agreement with you for 6 months for up to
                          20 hours per week at a rate of $2,500 per week. You
                          will still be eligible for all other Tekelec benefits
                          for which you qualify during this period. This
                          consulting agreement may be extended by mutual
                          agreement.

                 6.       I will recommend that the Compensation Committee of
                          the Board of Directors grant to you additional Stock
                          Options with an aggregate exercise cost of $300,000,
                          based on 100% of the closing price at November 22,
                          1995 of Tekelec Common Stock with vesting in 7
                          quarterly installments to commence 12/31/95 and
                          ending 6/30/97.

                 You will also be eligible for further grants of Stock Options
based on my recommendation and subject to the discretion of the Compensation
Committee of the Board. There can be no assurance, however, that such
recommendations will be made or approved for you.

                 7.       In the event of termination of your employment prior
                          to January 1, 1997, you would still be eligible to
                          receive your severance benefits in accordance with
                          the terms of the Officer Severance Plan. In addition,
                          if you are entitled to receive severance benefits
                          under the Officers Severance Plan, all options
                          granted to you prior to September 30, 1995 which
                          remain unvested at the date of termination would
                          immediately vest.

                 Over the next two years there are some significant and
exciting goals outlined below that I believe we have agreed you would like to
achieve for Tekelec with NSD and Eagle. Obviously, in a rapidly changing
environment new business opportunities will evolve that could change these
goals and we will keep this under review. *

         o       Continue to develop the NSD management team encompassing all
                 major functions of sales, engineering, marketing and customer
                 service. *

         o       Continue to develop the EAGLE product line and business to at
                 least $* in revenues and operating income of at least *% in
                 1997.

         *

                 Although this agreement is subject to Board approval, I do not
envision that it will not be approved.
