                                  EXHIBIT 10.19

                                SYMMETRICOM, INC.

                      CHANGE OF CONTROL RETENTION AGREEMENT

     This CHANGE OF CONTROL RETENTION AGREEMENT (the "Agreement") is made and
entered into by and between THOMAS W. STEIPP (the "Executive") and SYMMETRICOM,
INC. (the "Company"), effective as of the latest date set forth by the
signatures of the parties hereto below (the "Effective Date").

                                    RECITALS
                                    --------

     A. It is expected that the Company from time to time will consider the
possibility of an acquisition by another company or other change of control. The
Board of Directors of the Company (the "Board") recognizes that such
consideration can be a distraction to the Executive and can cause the Executive
to consider alternative employment opportunities. The Board has determined that
it is in the best interests of the Company and its stockholders to assure that
the Company will have the continued dedication and objectivity of the Executive,
notwithstanding the possibility, threat or occurrence of a Change of Control (as
defined below) of the Company.

     B. The Board believes that it is in the best interests of the Company and
its stockholders to provide the Executive with an incentive to continue his
employment and to motivate the Executive to maximize the value of the Company
upon a Change of Control for the benefit of its stockholders.

     C. The Board believes that it is imperative to provide the Executive with
retention/severance benefits following a Change of Control which provides the
Executive with enhanced financial security and provides incentive and
encouragement to the Executive to remain with the Company notwithstanding the
possibility of a Change of Control.

     D. Certain capitalized terms used in the Agreement are defined in Section 5
below.

     The parties hereto agree as follows:

1.   Term of Agreement. This Agreement shall terminate on the date that all
     -----------------
obligations of the parties hereto with respect to this Agreement have been
satisfied.

2.   Coordination with Employment Agreement. Prior to a Change of Control,
     --------------------------------------
payments, if any, to Executive upon termination of employment shall be
determined in accordance with the Employment Agreement between Executive and
Company, dated July 1, 2001. After a Change of Control, payments to Executive
upon termination of employment shall be determined in accordance with this
Agreement.

3.   Change of Control Retention/Severance Benefits.
     ----------------------------------------------

     (a)  Involuntary Termination other than for Cause, Death or Disability or
          --------------------------------------------------------------------
          Voluntary Termination for Good Reason Within 24 Months Following A
          ------------------------------------------------------------------
          Change of Control. If Executive's employment with the Company
          -----------------
          terminates within twenty four (24) months following a Change of
          Control by virtue of (A) an involuntary termination by the Company
          other than for Cause, (B) Executive's death or Disability, or (C) a
          Voluntary Termination for Good Reason, then the Company shall provide
          Executive with the following benefits:

          (i)   Base Salary and Target Bonus Payment. Within thirty (30) days
                ------------------------------------
                of the triggering event, pay Executive a lump sum equal to
                three (3) times the sum of (A) Executive's annual base salary
                as in effect as of the date of such termination, and (B) 100%
                of Executive's Target Bonus for the year prior to the year in
                which the payment occurs;

          (ii)  Equity Compensation Vesting. Immediately and fully vest
                ---------------------------
                Executive's outstanding stock options and shares of stock, if
                any, subject to restricted stock purchase agreements;

          (iii) COBRA and Life Insurance. Provide to Executive, upon his
                ------------------------
                termination of employment with the Company, one hundred percent
                (100%) Company-paid health, dental, vision and life insurance
                coverage at the same level of coverage as was provided to
                Executive immediately prior to the date of termination (the
                "Company-Paid Coverage"). If such coverage included the
                Executive's dependents immediately prior to the date of
                termination, such dependents shall also be covered at Company
                expense. Company-Paid Coverage shall continue until the earlier
                of (x) the end of the eighteenth (18th) month following the
                month in which the date of termination occurred, or (y) the date
                that the Executive and his dependents become covered under
                another employer's group health, dental, vision and life
                insurance plans that provide Executive and his dependents with
                comparable benefits and levels of coverage. For purposes of
                Title X of the Consolidated Budget Reconciliation Act of 1985
                ("COBRA"), the date of the "qualifying event" for Executive and
                his dependents shall be the date upon which the Company-Paid
                Coverage terminates.

     (b)  Voluntary Resignation; Termination for Cause. If the Executive's
          --------------------------------------------
          employment terminates by reason of the Executive's voluntary
          resignation (and is not a Voluntary Termination for Good Reason), or
          if the Executive is terminated for Cause, then the Executive shall not
          be entitled to receive severance or other benefits except for those
          (if any) as may then be established under the Company's then existing
          severance and benefits plans or pursuant to other written agreements
          with the Company, except that Executive shall receive the Company-Paid
          Coverage if he remains employed with the Company for twelve (12)
          months following a Change of Control.

                                       2

<PAGE>

     (c)  Termination After the Twenty Four Month Period Following a Change of
          --------------------------------------------------------------------
          Control. In the event the Executive's employment is terminated for any
          -------
          reason after the twenty four (24) month period following a Change of
          Control, then the Executive shall be entitled to receive severance and
          any other benefits only as may then be established under the Company's
          existing severance and benefits plans or pursuant to other written
          agreements with the Company.

4.   Taxation of Severance Benefits. In the event that the benefits provided for
     ------------------------------
in this Agreement or otherwise payable to the Executive constitute "parachute
payments" within the meaning of Section 280G of the Internal Revenue Code of
1986, as amended (the "Code"), and will be subject to the excise tax imposed by
Section 4999 of the Code, then Company shall pay Executive an amount ("Gross-Up
Payment") such that after payment by the Executive of all taxes (including any
interest or penalties imposed with respect to such taxes), including, without
limitation, any income taxes and excise tax imposed upon the Gross-Up Payment,
the Executive retains an amount of the Gross-Up Payment equal to the excise tax
imposed upon the Payments. Unless the Company and Executive otherwise agree in
writing, any determination required under this Section 5 shall be made in
writing by independent public accountants agreed to by the Company and Executive
(the "Accountants"), whose determination shall be conclusive and binding upon
Executive and the Company for all purposes. For purposes of making the
calculations required by this Section 5, the Accountants may make reasonable
assumptions and approximations concerning applicable taxes and may rely on
reasonable, good faith interpretations concerning the application of Sections
280G and 4999 of the Code. The Company and Executive shall furnish to the
Accountants such information and documents as the Accountants may reasonably
request in order to make a determination under this Section 5. The Company shall
bear all costs the Accountants may reasonable incur in connection with any
calculations contemplated by this Section 5.

5.   Definition of Terms. The following terms referred to in this Agreement
     -------------------
shall have the following meanings:

     (a)  Cause. Termination shall be for "Cause" if:
          -----

               mental illness, and, after (A) being warned in writing, and (B)
               having had a reasonable opportunity to cure (the length of such
               cure period to be determined by taking into account the nature of
               the conduct resulting in the warning, but in no event to be less
               than 30 days), continues to grossly neglect such duties or
               egregiously violate the specified Company policy;

          (ii) Executive commits a material act of dishonesty or fraud; or

                shall not exist merely by reason of a Change of Control to the
                extent that after such Change of Control, Executive is the Chief
                Executive Officer of the Company;

          (ii)  without Executive's express written consent, the relocation of
                Executive's principal place of employment to a location more

          (iii) any failure by Company or its affiliates to pay, or any

                assistance, or other benefits received by Executive prior to the

7.    Notice.
      -------

           mailed notices shall be addressed to him at the home address that
           he most recently communicated to the Company in writing. In the
           case of the Company, mailed notices shall be addressed to its

          termination under the provision so indicated, and shall specify the
          termination date (which shall be not more than 30 days after the
          giving of such notice). The failure by the Executive to include in the
          notice any fact or circumstance which contributes to a showing of
          Voluntary Termination for Good Reason shall not waive any right of the
          Executive hereunder or preclude the Executive from asserting such fact
          or circumstance in enforcing his rights hereunder.

8.   Miscellaneous Provisions***.
     ---------------------------

          any breach of, or of compliance with, any condition or provision of
          this Agreement by the other party shall be considered a waiver of any
          other condition or provision or of the same condition or provision at
          another time.

     (c)  Entire Agreement. No agreements, representations or understandings
          ----------------

          limitation the Interest-Bearing Loan, the Interest Free Loan, the
          Change of Control Retention Agreement, the Symmetricom Executive
          Medical Plan) have been made or entered into by either party with
          respect to the subject matter hereof. This Agreement represents the
          entire understanding of the parties hereto with respect to the subject
          matter hereof. To the extent the terms of this Agreement conflict in
          any way with the terms of any other agreement between the Company and
          the Executive, the terms of this Agreement shall control.

     (d)  Choice of Law. The validity, interpretation, construction and

     (e)  Severability. The invalidity or unenforceability of any provision or
          ------------
          provisions of this Agreement shall not affect the validity or
          enforceability of any other provision hereof, which shall remain in
          full force and effect.

     (f)  Counterparts. This Agreement may be executed in counterparts, each of
          ------------
          which shall be deemed an original, but all of which together will
          constitute one and the same document.
