Dear _____________:

         Allen Telecom Inc. (the "Corporation") considers it essential to the
best interests of its stockholders to foster the continuous employment of key
management personnel. In this connection, the Board of Directors of the
Corporation (the "Board") recognizes that, as is the case with many publicly
held corporations, the possibility of a change in control of the Corporation may
exist and that such possibility, and the uncertainty and questions which it may
raise among management, may result in the departure or distraction of management
personnel to the detriment of the Corporation and its stockholders.

         The Board has determined that appropriate steps should be taken to
reinforce and encourage the continued attention and dedication of members of the
Corporation's management, including yourself, to their assigned duties without
distraction in the face of potentially disturbing circumstances arising from the
possibility of a change in control of the Corporation. It is also the intention
of the Board to provide financial assistance to you in certain other
circumstances under which your employment with the Corporation terminates.

         In order to induce you to remain in the employ of the Corporation, the
Corporation agrees that you shall receive the severance benefits set forth in
this letter agreement (this "Agreement") in the event your employment with the
Corporation is terminated under the circumstances described below.

         1. TERM OF AGREEMENT. This term of this Agreement (the "Term") shall
commence on September 8, 1999, and shall continue through December 31, 2002;
PROVIDED, HOWEVER, that commencing on January 1, 2000, and each January 1
thereafter, the term of this Agreement shall automatically be extended for one
additional year unless, not later than September 30 of the preceding year, the
Corporation shall have given notice that it does not wish to extend this
Agreement; and PROVIDED, FURTHER, that if a change in control of the
Corporation, as defined in Section 3, shall have occurred during the original or
extended term of this Agreement, the term of this Agreement shall continue in
effect for a period of not less than 24 months beyond the month in which such
change in control occurred. In no event, however, shall the term of this
Agreement extend beyond the end of the calendar month in which your 65th
birthday occurs.

         2. COMPENSATION UPON TERMINATION PRIOR TO A CHANGE IN CONTROL. (i)
Prior to a change in control of the Corporation, if your employment by the
Corporation shall be terminated by the Corporation other than for Cause or
Disability (as these terms are defined in Subsections 4(iii) and 2(ii),
respectively) during the Term, then you shall be entitled to the benefits
provided below:

                  (a) the Corporation shall pay to you your full base salary
through the Date of Termination, at the rate in effect at the time Notice of
Termination is given (as these terms are defined in Subsections 4(vi) and 4(v),
respectively), no later than the fifth day following the Date of Termination,
plus accrued vacation pay and all other amounts to which you are entitled under
any compensation plan of the Corporation, at the time such payments are due;

                  (b) in lieu of any further salary payments to you for periods
subsequent to the Date of Termination, the Corporation shall pay as severance
pay to you, in regular pay periods until completely disbursed, total severance
pay equal to the sum of (1) six months of your monthly base salary as in effect
as of the Date of Termination and (2) the amount of such monthly base salary
multiplied by the number of your completed years of full-time employment with
the Corporation as of the Date of Termination; PROVIDED, HOWEVER, that in no
event shall the severance payments exceed 18 months' base salary; and

                  (c) during the period in which you are receiving the severance
payments the Corporation shall arrange to provide you with life, disability,
accident and group health insurance benefits substantially similar to those
which you were receiving immediately prior to the Notice of Termination;
PROVIDED, HOWEVER, that you will no longer be deemed to be an "employee" for
purposes of the Corporation's 1992 Stock Plan, 1982 Stock Plan, Employee
Before-Tax Savings Plan, Restricted Shares of common stock awarded under the
1992 Stock Plan or Corporate Retirement Plan or any successor plans thereto.
Benefits otherwise receivable by you pursuant to this paragraph (c) shall be
reduced to the extent comparable benefits are actually received by you from any
other source during such period, and any such benefits actually received by you
shall be reported to the Corporation. The use of any automobile furnished to you
by the Corporation shall continue until the earlier of (1) the date that is six
months after the Date of Termination or (2) the date you obtain employment with
another employer, and you agree that you will not remove such automobile from
the state in which you were last employed by the Corporation, and that upon any
such removal the Corporation shall be entitled to immediate possession of such
automobile and shall no longer furnish the use of such automobile to you.

                           (ii)     DISABILITY.  Your employment may be
terminated for "Disability" pursuant to this Section 2 (x) if, as a result of
your incapacity due to accident or physical or mental illness, you shall not
have substantially performed your duties with the Corporation on a full-time
basis for six consecutive months, or (y) if you become disabled in a manner that
shall prevent you from performing your duties with the Corporation, and within
30 days after written notice of termination is given you shall not have returned
to the full-time performance of your duties.

                           (iii)    NONCOMPETITION.  Benefits payable under
this Section 2 shall be forfeitable and shall be discontinued in the event that
you engage in a "Competitive Activity" or engage in conduct which is materially
injurious to the Corporation, monetarily or otherwise. A "Competitive Activity"
shall mean activity, without the written consent of an authorized officer

                                                                               2

of the Corporation, consisting of your participation in the management of, or
acting as a consultant for or employee of, any business operation of any
enterprise if such operation (a "Competitive Operation") is then in substantial
and direct competition with a principal business operation of the Corporation,
at the Date of Termination. A "Competitive Activity" shall not include (a) the
ownership of securities in any enterprise or of not more than five percent of
the outstanding securities of a "Competitive Operation", or (b) the
participation in the management of, or acting as a consultant for or employee
of, any enterprise or any business operation thereof, other than in connection
with a "Competitive Operation" of such enterprise.

                           (iv)     MITIGATION.  Severance benefits payable
under Section 2(i)(b) in excess of six months' salary shall be reduced by any
salary received by you from another employer and any consulting compensation
received by you from a prospective employer (other than consulting compensation
received by an independent consulting business conducted by you) during the
period during which you are receiving benefits under Section 2(i)(b), and any
such salary or consulting compensation received by you shall be reported by you
to the Corporation.

         3. CHANGE IN CONTROL. Except as provided in Section 2, no benefits
shall be payable hereunder unless there shall have been a change in control of
the Corporation during the Term, as set forth below. For purposes of this
Agreement, a "change in control of the Corporation" shall be deemed to have
occurred if:

                  (i) any "person", as such term is used in Sections 13(d) and
14(d) of the Securities Exchange Act of 1934, as amended (the "Exchange Act")
(other than the Corporation, any trustee or other fiduciary holding securities
under an employee benefit plan of the Corporation, or any corporation owned,
directly or indirectly, by the stockholders of the Corporation in substantially
the same proportions as their ownership of stock of the Corporation), is or
becomes the "beneficial owner" (as defined in Rule 13d-3 under the Exchange
Act), directly or indirectly, of securities of the Corporation representing 30
percent or more of the combined voting power of the Corporation's then
outstanding securities;

                  (ii) during any period of two consecutive years, individuals
who at the beginning of such period constitute the Board, and any new director
(other than a director designated by a person who has entered into an agreement
with the Corporation to effect a transaction described in clause (i), (iii) or
(iv) of this Section) whose election by the Board or nomination for election by
the Corporation's stockholders was approved by a vote of at least two-thirds
(2/3) of the directors then still in office who either were directors at the
beginning of the period or whose election or nomination for election was
previously so approved, cease for any reason to constitute at least a majority
thereof;

                  (iii) the stockholders of the Corporation approve a merger or
consolidation of the Corporation with any other corporation, other than (a) a
merger or consolidation which would result in the voting securities of the
Corporation outstanding immediately prior thereto continuing to represent
(either by remaining outstanding or by being converted into voting securities of
the surviving entity) more than 80 percent of the combined voting power of the
voting securities of the Corporation or such surviving entity outstanding
immediately after such merger or consolidation or (b) a merger or consolidation
effected to implement a recapitalization of the Corporation (or similar
transaction) in which no "person" (as hereinabove defined)

                                                                               3
<PAGE>   4

acquires more than 30 percent of the combined voting power of the Corporation's
then outstanding securities; or

                  (iv) the stockholders of the Corporation approve a plan of
complete liquidation of the Corporation or an agreement for the sale or
disposition by the Corporation of all or substantially all of the Corporation's
assets.

         4.       TERMINATION FOLLOWING CHANGE IN CONTROL.

                  (i) GENERAL. If any of the events described in Section 3
constituting a change in control of the Corporation shall have occurred during
the Term, you shall be entitled to the benefits provided in Section 5(iii) upon
the subsequent termination of your employment during the term of this Agreement
unless such termination is (a) because of your death or Disability (as such term
is defined in Subsection 4(ii) below), (b) by the Corporation for Cause, or (c)
by you other than for Good Reason.

                  (ii) DISABILITY. Notwithstanding Subsection 4(i), you may not
be terminated for "Disability" pursuant to this Section 4 unless, as a result of
your incapacity due to accident or physical or mental illness, you shall not
have substantially performed your duties with the Corporation on a full-time
basis for six consecutive months following the occurrence of a change of control
of the Corporation.

                  (iii) CAUSE. Termination by the Corporation of your employment
for "Cause" shall mean termination (a) upon the willful and continued failure by
you to substantially perform your duties with the Corporation (other than any
such failure resulting from your death or incapacity due to accident or physical
or mental illness or any such actual or anticipated failure after the issuance
of a Notice of Termination (as defined in Subsection 4(v)) by you for Good
Reason (as defined in Subsection 4(iv))), after a written demand for substantial
performance is delivered to you by the Board, which demand specifically
identifies the manner in which the Board believes that you have not
substantially performed your duties, (b) the willful engaging by you in an act
or acts of dishonesty constituting a felony under the laws of the United States
or any state thereof and resulting or intended to result directly or indirectly
in gain or personal enrichment at the expense of the Corporation, or your
conviction of a felony under the laws of the United States or any state thereof,
or (c) the willful engaging by you in conduct which is demonstrably and
materially injurious to the Corporation, monetarily or otherwise. For purposes
of this Subsection, no act, or failure to act, on your part shall be deemed
"willful" unless done, or omitted to be done, by you not in good faith and
without reasonable belief that your action or omission was in the best interest
of the Corporation. Notwithstanding the foregoing, you shall not be deemed to
have been terminated for Cause unless and until there shall have been delivered
to you a copy of a resolution duly adopted by the affirmative vote of not less
than a majority of the entire membership of the Board at a meeting of the Board
(after reasonable notice to you and an opportunity for you, together with your
counsel, to be heard before the Board), finding that in the good faith opinion
of the Board you were guilty of conduct set forth above in this Subsection and
specifying the particulars thereof in detail.

                  (iv) GOOD REASON. Termination by you of your employment for
"Good Reason" for purposes of Section 5(iii) shall mean, without your express
written consent, the occurrence after a change in control of the Corporation of
any of the following circumstances

                                                                               4
<PAGE>   5

unless, in the case of paragraphs (a), (e), (f), (g) or (h), such circumstances
are fully corrected prior to the Date of Termination (as defined in Section
4(vi)) given in respect thereof:

                           (a) the assignment to you of any duties inconsistent
         with the position with the Corporation that you held immediately prior
         to the change in control of the Corporation, or a significant adverse
         alteration in the nature or status of your responsibilities or the
         conditions of your employment from those in effect immediately prior to
         such change in control;

                           (b) a reduction by the Corporation in your annual
         base salary as in effect on the date hereof or as it may be increased
         from time to time, except for across-the-board salary reductions
         similarly affecting all management personnel of the Corporation and all
         management personnel of any person in control of the Corporation;

                           (c) the relocation of the Corporation's offices at
         which you are principally employed immediately prior to the date of the
         change in control of the Corporation to a location more than 25 miles
         from such location, or the Corporation's requiring you to be based
         anywhere other than the Corporation's offices at such location, except
         for required travel on the Corporation's business to an extent
         substantially consistent with your business travel practices
         immediately prior to the date of the change in control of the
         Corporation;

                           (d) the failure by the Corporation to pay to you any
         portion of your current compensation or to pay to you any portion of an
         installment of deferred compensation under any deferred compensation
         program of the Corporation within seven days of the date such
         compensation is due;

                           (e) the failure by the Corporation to continue in
         effect any material compensation or benefit plan in which you
         participate immediately prior to the change in control of the
         Corporation, unless an equitable arrangement (embodied in an ongoing
         substitute or alternative plan) has been made with respect to such
         plan, or the failure by the Corporation to continue your participation
         therein (or in such substitute or alternative plan) on a basis not
         materially less favorable, both in terms of the amount of benefits
         provided and the level of your participation relative to other
         participants, as existed at the time of the change in control of the
         Corporation;

                           (f) the failure by the Corporation to continue to
         provide you with benefits substantially similar to those enjoyed by you
         under any of the Corporation's life, medical, health and accident, or
         disability insurance or plans in which you were participating at the
         time of the change in control of the Corporation, the taking of any
         action by the Corporation which would directly or indirectly materially
         reduce any of such benefits, or the failure by the Corporation to
         provide you with the number of paid vacation days to which you are
         entitled on the basis of years of service with the Corporation in
         accordance with the Corporation's normal vacation policy in effect at
         the time of the change in control of the Corporation;

                                                                               5
<PAGE>   6

                           (g)      the failure of the Corporation to obtain a
                                    satisfactory agreement from any successor
                                    to assume and agree to perform this
                                    Agreement, as contemplated in Section 6
                                    hereof; or

                           (h)      any purported termination of your employment
                                    that is not effected pursuant to a Notice of
                                    Termination satisfying the requirements of
                                    Subsection (v) hereof (and, if applicable,
                                    the requirements of Subsection (iii)
                                    hereof), which purported termination shall
                                    not be effective for purposes of this
                                    Agreement.

Your right to terminate your employment pursuant to this Subsection shall not be
affected by your incapacity due to accident or physical or mental illness. Your
continued employment shall not constitute consent to, or a waiver of rights with
respect to, any circumstance constituting Good Reason hereunder.

                  (v) NOTICE OF TERMINATION. Any purported termination of your
employment by the Corporation or by you shall be communicated by written Notice
of Termination to the other party hereto in accordance with Section 7. "Notice
of Termination" shall mean a notice that shall indicate the specific termination
provision in this Agreement relied upon and shall set forth in reasonable detail
the facts and circumstances claimed to provide a basis for termination of your
employment under the provision so indicated.

                  (vi) DATE OF TERMINATION, ETC. "Date of Termination" shall
mean (a) if your employment is terminated for Disability, 30 days after Notice
of Termination is given (provided that you shall not have returned to the
full-time performance of your duties during such 30-day period), and (b) if your
employment is terminated pursuant to Subsection (iii) or (iv) hereof, or
pursuant to Section 2, or for any other reason (other than Disability), the date
specified in the Notice of Termination ( which, in the case of a termination for
Cause shall not be less than 30 days from the date such Notice of Termination is
given, and in the case of a termination for Good Reason shall not be less than
15 nor more than 60 days from the date such Notice of Termination is given);
PROVIDED, HOWEVER, that if within 30 days after any Notice of Termination is
given following a change in control of the Corporation, the party receiving such
Notice of Termination notifies the other party that a dispute exists concerning
the termination, then the Date of Termination shall be the date on which the
dispute is finally determined, whether by mutual written agreement of the
parties, by a binding arbitration award, or by a final judgment, order or decree
of a court of competent jurisdiction (which is not appealable or with respect to
which the time for appeal therefrom has expired and no appeal has been
perfected); and PROVIDED, FURTHER, that the Date of Termination shall be
extended by a notice of dispute only if such notice is given in good faith and
the party giving such notice pursues the resolution of such dispute with
reasonable diligence. Notwithstanding the pendency of any such dispute, if the
Notice of Termination is given following a change in control of the Corporation,
the Corporation will continue to pay you your full compensation in effect when
the notice giving rise to the dispute was given (including, but not limited to,
base salary) and continue you as a participant in all compensation, benefit and
insurance plans in which you were participating when the notice giving rise to
the dispute was given, until the dispute is finally resolved in accordance with
this Subsection; PROVIDED, HOWEVER, that you will no longer be deemed to be an
"employee" for purposes of the Corporation's 1992 Stock Plan, 1982 Stock Plan,
Employee Before-Tax Savings Plan, Restricted Shares of common stock awarded
under the 1992 Stock Plan or Corporate

                                                                               6

Retirement Plan or any successor plans thereto. Amounts paid under this
Subsection are in addition to all other amounts due under this Agreement, and
shall not be offset against or reduce any other amounts due under this Agreement
and shall not be reduced by any compensation earned by you as the result of
employment by another employer.

         5. COMPENSATION UPON TERMINATION OR DURING DISABILITY FOLLOWING A
CHANGE IN CONTROL. Following a change in control of the Corporation during the
Term, you shall be entitled to the following benefits during a period of
disability, or upon termination of your employment, as the case may be, provided
that such period or termination occurs during the term of this Agreement:

                  (i) During any period that you fail to perform your full-time
duties with the Corporation as a result of incapacity due to accident or
physical or mental illness, you shall receive all compensation payable to you
under the Corporation's disability plan or program or other similar plan during
such period, until this Agreement is terminated pursuant to Section 4(ii)
hereof. Thereafter, or in the event your employment shall be terminated by
reason of your death, your benefits shall be determined under the Corporation's
retirement, insurance and other compensation programs then in effect in
accordance with the terms of such programs.

                  (ii) If your employment shall be terminated by the Corporation
for Cause or by you other than for Good Reason, the Corporation shall pay you
your full base salary through the Date of Termination, at the rate in effect at
the time Notice of Termination is given, no later than the fifth day following
the Date of Termination, plus accrued vacation pay and all other amounts to
which you are entitled under any compensation plan of the Corporation at the
time such payments are due, and the Corporation shall have no further
obligations to you under this Agreement.

                  (iii) If your employment by the Corporation shall be
terminated by you for Good Reason or by the Corporation other than for Cause or
Disability, then you shall be entitled to the benefits provided below:

                           (a) the Corporation shall pay to you your full base
         salary through the Date of Termination, at the rate in effect at the
         time Notice of Termination is given, no later than the fifth day
         following the Date of Termination, plus accrued vacation pay and all
         other amounts to which you are entitled under any compensation plan of
         the Corporation at the time such payments are due;

                           (b) in lieu of any further salary payments to you for
         periods subsequent to the Date of Termination, the Corporation shall
         pay as severance pay to you, at the time specified in Subsection (v), a
         lump sum severance payment (together with the payments provided in
         paragraph (c) below, the "Severance Payments") equal to the sum of :
         (1) one year of your annual base salary as in effect as of the Date of
         Termination or immediately prior to the change in control of the
         Corporation, whichever is greater; (2) an amount equal to the highest
         annual incentive compensation paid to you in the three years prior to
         the Date of Termination; (3) if the Board in its sole discretion shall
         determine, an additional discretionary bonus payment; and (4) fifteen
         percent of the sum of the amounts set forth in clauses (1) and (2),
         multiplied by the number of your completed years of full-time
         employment with the Corporation as of the Date of Termination;

                                                                               7
<PAGE>   8

                           (c) in lieu of shares of common stock of the
         Corporation ("Common Shares") issuable upon exercise of outstanding
         options, other than options qualifying as incentive stock options
         ("ISOs") under Section 422 of the Internal Revenue Code of 1986, as
         amended (the "Code"), which ISOs were granted on or before the date
         hereof ("Options"), and stock appreciation rights ("SARs"), if any,
         granted to you under the Corporation's 1982 Stock Plan or 1992 Stock
         Plan, or any successor plan thereto (which Options shall be canceled
         upon the making of the payment referred to below), the Corporation
         shall pay to you, at the time specified in Subsection (v), an amount in
         cash equal to the product of (1) the excess of, in the case of an ISO
         granted after the date hereof, the closing price of Common Shares as
         reported on the New York Stock Exchange on or nearest the Date of
         Termination (or, if not listed on such exchange, on a nationally
         recognized exchange or quotation system on which trading volume in the
         Common Shares is highest) and, in the case of all other options, the
         higher of such closing price or the highest per share price for Common
         Shares actually paid in connection with any change in control of the
         Corporation, over the per share option price of each Option held by you
         (whether or not then fully exercisable), and (2) the number of Common
         Shares covered by each such Option;

                           (d) the Corporation shall pay to you all legal fees
         and expenses incurred by you as a result of such termination (including
         all such fees and expenses, if any, incurred in contesting or disputing
         any such termination or in seeking to obtain or enforce any right or
         benefit provided by this Agreement or in connection with any tax audit
         or proceeding to the extent attributable to the application of Section
         4999 of the Code to any payment or benefit provided hereunder); and

                           (e) for a period of months after such termination
         that is equal in number to the sum of (1) twelve, plus (2) the product
         of (x) 0.15, multiplied by (y) the number of your completed years of
         full-time employment with the Corporation as of the Date of
         Termination, multiplied by (z) 12, but in no event exceeding 36 months,
         the Corporation shall arrange to provide you with life, disability,
         accident and group health insurance benefits substantially similar to
         those which you were receiving immediately prior to the Notice of
         Termination. Benefits otherwise receivable by you pursuant to this
         paragraph (e) shall be reduced to the extent comparable benefits are
         actually received by you from any other source during such period
         following your termination, and any such benefits actually received by
         you shall be reported to the Corporation.

                  (iv) Notwithstanding anything to the contrary contained in
this Agreement, in the event that, by reason of Section 280G of the Code, any
payment or benefit received or to be received by you in connection with a change
in control of the Corporation or the termination of your employment whether
payable pursuant to the terms of this Agreement or any other plan, arrangement
or agreement (the "Contract Payments") with the Corporation, its successors, any
person whose actions result in a change in control or any corporation affiliated
(or which, as a result of the completion of the transactions causing a change in
control will become affiliated) (an "Affiliate") with the Corporation within the
meaning or Section 1504 of the Code (collectively with the Contract Payments,
"Total Payments")), would not be deductible (in whole or in part) by the
Corporation, an Affiliate or other person making such payment or providing such
benefit, the Severance Payments shall be reduced (and, if Severance Payments are
reduced

                                                                               8
<PAGE>   9

to zero, other Contract Payments shall first be reduced and other Total Payments
shall thereafter be reduced) until no portion of the Total Payments is not
deductible by reason of Section 280G of the Code. For purposes of this
limitation (a) no portion of the Total Payments the receipt or enjoyment of
which you shall have effectively waived in writing prior to the date of payment
of the Severance Payments shall be taken into account, (b) no portion of the
Total Payments shall be taken into account which in the opinion of tax counsel
selected by the Corporation's independent auditors and acceptable to you does
not constitute a "parachute payment" within the meaning of Section 280G(b)(2) of
the Code (without regard to Subsection (A)(ii) thereof), (c) the Severance
Payments (and, thereafter, other Contract Payments and other Total Payments)
shall be reduced only to the extent necessary so that the Total Payments (other
than those referred to in clauses (a) and (b)), in their entirety constitute
reasonable compensation for services actually rendered within the meaning of
Section 280G(b)(4) of the Code, in the opinion of the tax counsel referred to in
clause (b), and (d) the value of any noncash benefit or any deferred payment or
benefit included in the Total Payments shall be determined by the Corporation's
independent auditors in accordance with the principles of Sections 280G(d)(3)
and (4) of the Code.

                  (v) The payments provided for in paragraphs (b) and (c) above
shall be made not later than the fifth day following the Date of Termination;
PROVIDED, HOWEVER, that if the amounts of such payments cannot be finally
determined on or before such day, the Corporation shall pay to you on such day
an estimate, as determined in good faith by the Corporation, of the minimum
amount of such payments and shall pay the remainder of such payments (together
with interest at the rate provided in Section 1274(b)(2)(B) of the Code) as soon
as the amount thereof can be determined but in no event later than the 30th day
after the Date of Termination. In the event that the amount of the estimated
payments exceeds the amount subsequently determined to have been due, such
excess shall constitute a loan by the Corporation to you, payable on the fifth
day after demand by the Corporation (together with interest at the rate provided
in Section 1274(b)(2)(B) of the Code).

                  (vi) Except as provided in Subsection (iii)(e) hereof, you
shall not be required to mitigate the amount of any payment provided for in this
Section 5 by seeking other employment or otherwise, nor shall the amount of any
payment or benefit provided for in this Section 5 be reduced by any compensation
earned by you as the result of employment by another employer, by retirement
benefits, by offset against any amount claimed to be owed by you to the
Corporation, or otherwise.

                  (vii) NONCOMPETITION. Benefits payable under this Section 5
shall be forfeitable and shall be discontinued in the event that during the
one-year period following the Date of Termination you (A) engage in a
Competitive Activity (as defined in Section 2(iii)) or (B) engage in conduct
which is materially injurious to the Corporation, monetarily or otherwise.

         6. SUCCESSORS; BINDING AGREEMENT. (i) The Corporation will require any
successor (whether direct or indirect, by purchase, merger, consolidation or
otherwise) to all or substantially all of the business and/or assets of the
Corporation to expressly assume and agree to perform this Agreement in the same
manner and to the same extent that the Corporation would be required to perform
it if no such succession had taken place. Failure of the Corporation to obtain
such assumption and agreement prior to the effectiveness of any such succession
shall be a breach of this Agreement and shall entitle you to compensation from
the Corporation in the same amount and on the same terms to which you would be
entitled hereunder if you terminate

                                                                               9
<PAGE>   10

your employment for Good Reason following a change in control of the
Corporation, except that for purposes of implementing the foregoing, the date on
which any such succession becomes effective shall be deemed the Date of
Termination. As used in this Agreement, "Corporation" shall mean the Corporation
as hereinbefore defined and any successor to its business and/or assets as
aforesaid which assumes and agrees to perform this Agreement by operation of
law, or otherwise.

                  (ii) This Agreement shall inure to the benefit of and be
enforceable by you and your personal or legal representatives, executors,
administrators, successors, heirs, distributees, devisees and legatees. If you
should die while any amount would still be payable to you hereunder had you
continued to live, all such amounts, unless otherwise provided herein, shall be
paid in accordance with the terms of this Agreement to your devisee, legatee or
other designee or, if there is no such designee, to your estate.

         7. NOTICES. For the purpose of this Agreement, notices and all other
communications provided for in this Agreement shall be in writing and shall be
deemed to have been duly given when delivered or mailed by United States
certified or registered mail, return receipt requested, postage prepaid, or by
recognized overnight delivery service, in each case addressed to the respective
addresses set forth on the first page of this Agreement, provided that all
notices to the Corporation shall be directed to the attention of the Board with
a copy to the Secretary of the Corporation, or to such other address as either
party may have furnished to the other in writing in accordance herewith, except
that notice of change of address shall be effective only upon receipt.

         8. MISCELLANEOUS. No provision of this Agreement may be modified,
waived or discharged unless such waiver, modification or discharge is agreed to
in writing and signed by you and such officer as may be specifically designated
by the Board. No waiver by either party hereto at any time of any breach by the
other party hereto of, or compliance with, any condition or provision of this
Agreement to be performed by such other party shall be deemed a waiver of
similar or dissimilar provisions or conditions at the time or at any prior to
subsequent time. No agreements or representations, oral or otherwise, express or
implied, with respect to the subject matter hereof have been made by either
party which are not expressly set forth in this Agreement. The validity,
interpretation, construction and performance of this Agreement shall be governed
by the laws of the State of Ohio without regard to its conflicts of law
principles. All references to Sections of the Exchange Act or the Code shall be
deemed also to refer to any successor provisions to such sections. Any payments
provided for hereunder shall be paid net of any applicable withholding required
under federal, state or local law. The obligations of the Corporation under
Sections 2 and 5 shall survive the expiration of the term of this Agreement.

         9. VALIDITY. The invalidity or unenforceability of any provision of
this Agreement shall not affect the validity or enforceability of any other
provision of this Agreement, which shall remain in full force and effect.

         10. COUNTERPARTS. This Agreement may be executed in several
counterparts, each of which shall be deemed to be an original but all of which
together will constitute one and the same instrument.

         11. ARBITRATION. Following a change in control of the Corporation, any
dispute or controversy between the Corporation and you arising under or in
connection with this Agreement

                                                                              10
<PAGE>   11

shall be settled exclusively by arbitration, conducted before a panel of three
arbitrators in Cleveland, Ohio, in accordance with the rules of the American
Arbitration Association then in effect. Judgment may be entered on the
arbitrator's award in any court having jurisdiction; PROVIDED, HOWEVER, that you
shall be entitled to seek specific performance of your right to be paid until
the Date of Termination during the pendency of any dispute or controversy
arising under or in connection with this Agreement.

         12. ENTIRE AGREEMENT. This Agreement sets forth the entire agreement of
the parties hereto in respect of the subject matter contained herein and
supersedes all other agreements, promises, covenants, arrangements,
communications, representations or warranties, whether oral or written, by any
officer, employee or representative of any party hereto including, without
limitation, the Corporation's Key Employee Severance Policy; and any other
agreement of the parties hereto in respect of the subject matter contained
herein is hereby terminated and canceled.

         If this letter sets forth our agreement on the subject matter hereof,
kindly sign and return to the Corporation the enclosed copy of this letter,
which will then constitute our agreement on this subject.

                                   Sincerely,

                                                                  Exhibit 10(ll)

                           CHANGE IN CONTROL AGREEMENT

         This Change in Control Agreement (this "Agreement"), dated as of
September 8, 1999, is by and between Allen Telecom Inc., a Delaware corporation
(the "Corporation"), and Philip William Colburn ("Colburn").

                                    RECITALS:

         A. The Board of Directors of the Corporation (the "Board") has
recognized that the Corporation may be vulnerable to a change in control
transaction.

         B. In order to induce Colburn to remain as a consultant to the
Corporation, the Corporation agrees to pay to Colburn a Change in Control
Payment (as defined in Section 2(a)) in the event that a Change in Control (as
defined in Section 2(b)) of the Corporation occurs during the Term (as defined
in Section 1) as described below.

                                   AGREEMENT:

         NOW, THEREFORE, in consideration of the premises and other good and
valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, Colburn and the Corporation agree as follows:

         1. TERM OF AGREEMENT. The term of this Agreement (the "Term") shall
commence on September 8, 1999, and shall continue through December 31, 2002;
PROVIDED, HOWEVER, that commencing on January 1, 2000, and each January 1
thereafter, the term of this Agreement shall automatically be extended for one
additional year unless, not later than September 30 of the preceding year, the
Corporation shall have given notice that it does not wish to extend this
Agreement; and PROVIDED, FURTHER, that this Agreement shall automatically
terminate in the event that Colburn ceases to be a consultant to the Corporation
for any reason.

         2. CHANGE IN CONTROL PAYMENT. (a) AMOUNT. If a Change in Control of the
Corporation shall occur during the Term, the Corporation shall pay to Colburn
$1,000,000.00 (or such higher amount as the Board may determine in its sole
discretion) (the "Change in Control Payment"), subject to the conditions and
pursuant to the terms set forth in this Section 2.

         (b) CHANGE IN CONTROL. No benefits shall be payable hereunder unless
there shall have been a change in control of the Corporation during the Term as
set forth below. For purposes of this Agreement, a "Change in Control" of the
Corporation shall be deemed to have occurred if:

                  (i) any "person", as such term is used in Sections 13(d) and
         14(d) of the Securities Exchange Act of 1934, as amended (the "Exchange
         Act") (other than the Corporation, any trustee or other fiduciary
         holding securities under an employee benefit plan of the Corporation,
         or any corporation owned, directly or indirectly, by the stockholders
         of the Corporation in substantially the same proportions as their
         ownership of stock of the Corporation), is or becomes the "beneficial
         owner" (as defined in Rule 13d-3 under the Exchange Act), directly or
         indirectly, of securities of the Corporation

<PAGE>   2

         representing 30% or more of the combined voting power of the
         Corporation's then outstanding securities;

                  (ii) during any period of two consecutive years, individuals
         who at the beginning of such period constitute the Board, and any new
         Director (other than a Director designated by a person who has entered
         into an agreement with the Corporation to effect a transaction
         described in clause (i), (iii) or (iv) of this Section 2(b)) whose
         election by the Board or nomination for election by the Corporation's
         stockholders was approved by a vote of at least two-thirds of the
         Directors then still in office who either were Directors at the
         beginning of the period or whose election or nomination for election
         was previously so approved, cease for any reason to constitute at least
         a majority thereof;

                  (iii) the stockholders of the Corporation approve a merger or
         consolidation of the Corporation with any other corporation, other than
         (a) a merger or consolidation which would result in the voting
         securities of the Corporation outstanding immediately prior thereto
         continuing to represent (either by remaining outstanding or by being
         converted into voting securities of the surviving entity) more than 80%
         of the combined voting power of the voting securities of the
         Corporation or such surviving entity outstanding immediately after such
         merger or consolidation or (b) a merger or consolidation effected to
         implement a recapitalization of the Corporation (or similar
         transaction) in which no "person" (as defined in Section 2(b)(i))
         acquires more than 30% of the combined voting power of the
         Corporation's then outstanding securities; or

                  (iv) the stockholders of the Corporation approve a plan of
         complete liquidation of the Corporation or an agreement for the sale or
         disposition by the Corporation of all or substantially all of the
         Corporation's assets.

         (c) REDUCTION. Notwithstanding anything to the contrary contained in
this Agreement, in the event that, by reason of Section 280G of the Internal
Revenue Code of 1986, as amended (the "Code"), any payment or benefit received
or to be received by Colburn in connection with a change in control of the
Corporation whether payable pursuant to the terms of this Agreement or any other
plan, arrangement or agreement with the Corporation, its successors, any person
whose actions result in a change in control or any corporation affiliated (or
which, as a result of the completion of the transactions causing a change in
control will become affiliated) (an "Affiliate") with the Corporation within the
meaning or Section 1504 of the Code (collectively, "Total Payments"), would not
be deductible (in whole or in part) by the Corporation, an Affiliate or other
person making such payment or providing such benefit, the Change in Control
Payment shall be reduced until no portion of the Total Payments is not
deductible by reason of Section 280G of the Code.

         (d) TIME OF PAYMENT. The payments provided for in this Section 2 shall
be made not later than the fifth business day following the date that the Change
in Control is consummated (the "Closing Date").

         3. SUCCESSORS; BINDING AGREEMENT. (a) The Corporation will require any
successor (whether direct or indirect, by purchase, merger, consolidation or
otherwise) to all or substantially all of the business and/or assets of the
Corporation to expressly assume and agree to perform this Agreement in the same
manner and to the same extent that the Corporation would

                                                                               2
<PAGE>   3

be required to perform it if no such succession had taken place. As used in this
Agreement, "Corporation" shall mean the Corporation as hereinbefore defined and
any successor to its business and/or assets as aforesaid which assumes and
agrees to perform this Agreement by operation of law, or otherwise.

                  (b) This Agreement shall inure to the benefit of and be
enforceable by Colburn and his personal or legal representatives, executors,
administrators, successors, heirs, distributees, devisees or legatees. If
Colburn should die after the occurrence of a Change in Control while any amount
would still be payable to him hereunder had he continued to live, all such
amounts, unless otherwise provided herein, shall be paid in accordance with the
terms of this Agreement to Colburn's devisee, legatee or other designee or, if
there is no such designee, to his estate.

         4. MISCELLANEOUS. No provision of this Agreement may be modified,
waived or discharged unless such waiver, modification or discharge is agreed to
in writing and signed by Colburn and such officer as may be specifically
designated by the Board. No waiver by either party hereto at any time of any
breach by the other party hereto of, or compliance with, any condition or
provision of this Agreement to be performed by such other party shall be deemed
a waiver of similar or dissimilar provisions or conditions at the time or at any
prior to subsequent time. No agreements or representations, oral or otherwise,
express or implied, with respect to the subject matter hereof have been made by
either party which are not expressly set forth in this Agreement. The validity,
interpretation, construction and performance of this Agreement shall be governed
by the laws of the State of Ohio without regard to its conflicts of law
principles. All references to Sections of the Exchange Act or the Code shall be
deemed also to refer to any successor provisions to such sections. Any payments
provided for hereunder shall be paid net of any applicable withholding required
under federal, state or local law. The obligations of the Corporation under
Section 2 shall survive the expiration of the term of this Agreement.

         5. VALIDITY. The invalidity or unenforceability of any provision of
this Agreement shall not affect the validity or enforceability of any other
provision of this Agreement, which shall remain in full force and effect.

         6. COUNTERPARTS. This Agreement may be executed in several
counterparts, each of which shall be deemed to be an original but all of which
together will constitute one and the same instrument.

         7. ARBITRATION. Following a Change in Control of the Corporation, any
dispute or controversy between the Corporation and Colburn arising under or in
connection with this Agreement shall be settled exclusively by arbitration,
conducted before a panel of three arbitrators in Cleveland, Ohio, in accordance
with the rules of the American Arbitration Association then in effect. Judgment
may be entered on the arbitrator's award in any court having jurisdiction.

                                                                               3

         IN WITNESS WHEREOF, Colburn has executed, and the Corporation has
caused its duly authorized representative to execute, this Agreement as of the
date first above written.
