            6. Restrictive Covenants.

                  (a) During such time as you shall be employed by the Company,
and for a period of two years thereafter, you shall not, without the written
consent of the Board of Directors, directly or indirectly become associated
with, render services to invest in, represent, advise or otherwise participate
as an officer, employee, director, stockholder, partner, agent of or consultant
for, any business which is conducted in any of the jurisdictions in which the
Company's business is conducted and which is competitive with the business in
which the Company is engaged at the time your employment with the Company
ceases; provided, however, that: (1) nothing herein shall prevent you from
acquiring up to 3% of the securities of any company listed on a national
securities exchange or quoted on the NASDAQ quotation system, provided your
involvement with any such company is solely that of a stockholder; and (2) if
your employment hereunder shall be terminated by the Company without Just Cause
(as defined below) therefor having been given by you, then the foregoing
noncompetition agreement shall, at the election of the Company, be effective for
a period of up to two years after such termination provided the Company shall
pay you during such period at a per annum rate equal to your Base Salary in
effect at the time of such termination. In the event the Company is making
payments to you pursuant to clause (2) of the immediately preceding sentence,
the Company shall have the right to terminate such payments at any time upon 30
days' prior written notice to you, in which event the foregoing noncompetition
agreement shall terminate on the 30th day following your receipt of such notice.

                  (b) The parties hereto intend that the covenant contained in
this Section 6 shall be deemed a series of separate covenants for each country,
state, county and city in

                                       4
<PAGE>

which the Company's business is conducted. If, in any judicial proceeding, a
court shall refuse to enforce all the separate covenants deemed included in this
Section 6 because, taken together, they cover too extensive a geographic area,
the parties intend that those of such covenants (taken in order of the
countries, states, counties and cities therein which are least populous) which
if eliminated would permit the remaining separate covenants to be enforced in
such proceeding shall, for the purpose of such proceeding, be deemed eliminated
from the provisions of this Section 6.

            7. Confidentiality, Non-Interference and Proprietary Information.

                  (a) Confidentiality. In the course of your employment by the
Company hereunder, you will have access to confidential or proprietary data or
information of the Company and its operations. You will not at any time divulge
or communicate to any person nor shall you direct any Company employee to
divulge or communicate to any person (other than to a person bound by
confidentiality obligations similar to those contained herein and other than as
necessary in performing your duties hereunder) or use to the detriment of the
Company or for the benefit of any other person, any of such data or information.
The provisions of this Section 7(a) shall survive your employment hereunder,
whether by the normal expiration thereof or otherwise. The term "confidential or
proprietary data or information" as used in this Agreement shall mean
information not generally available to the public including, without limitation,
personnel information, financial information, customer lists, supplier lists,
trade secrets, information regarding operations, systems, services, knowhow,
computer and any other processed or collated data, computer programs, pricing,
marketing and advertising data.

                  (b) Non-Interference. You agree that you will not at any time
after the termination of your employment by the Company, for your own account or
for the account of any other person, tortiously interfere with the Company's
relationship with any of its suppliers, customers or employees.

                  (c) Proprietary Information and Disclosure. You agree that you
will at all times promptly disclose to the Company (which, for the purposes of
this Section 7, shall include the Company and any subsidiaries and affiliates of
the Company), in such form and manner as the Company may reasonably require, any
inventions, improvements or procedural or methodological innovations, programs
methods, forms, systems, services, designs, marketing ideas, products or
processes (whether or not capable of being trade-marked, copyrighted or
patented) conceived or developed or created by you during or in connection with
your employment hereunder and which relate to the business of the Company and
any subsidiaries or affiliates ("Intellectual Property"). You agree that all
such Intellectual Property shall be the sole property of the Company. You
further agree that you will execute such instruments and perform such acts as
may reasonably be requested by the Company to transfer to and perfect in the
Company all legally protectible rights in such Intellectual Property.

                  (d) Return of Property. All written materials, records and
documents made by you or coming into your possession during your employment
concerning any products, processes or equipment, manufactured, used, developed,
investigated or considered by the Company or otherwise concerning the business
or affairs of the Company, shall be the sole property of the Company, and upon
termination of your employment, or upon request of the Company during your
employment, you shall promptly deliver same to the Company. In addition, upon

                                       6
<PAGE>

termination of your employment, or upon request of the Company during your
employment, you will deliver to the Company all other Company property in your
possession or under your control, including, but not limited to, financial
statements, marketing and sales data, patent applications, drawings and other
documents, and all Company credit cards and automobiles.

            8. Equitable Relief. With respect to the covenants contained in
Sections 6 and 7 of this Agreement, you agree that any remedy at law for any
breach of said covenants may be inadequate and that the Company shall be

equitable relief to enforce its rights hereunder or any other relief a court
might award.

            9. Earlier Termination. Your employment hereunder shall terminate

of renewal) on the following terms and conditions:

                  (a) This Agreement shall terminate automatically on the date
of your death.

                  (b) This Agreement shall be terminated if you are unable to
perform your duties hereunder for 90 days (whether or not continuous) during any
period of 360 consecutive days by reason of physical or mental disability. The
disability shall be deemed to have occurred on the 90th day of your absence or
lack of adequate performance.

                  (c) This Agreement shall terminate immediately upon the
Company's sending you written notice terminating your employment hereunder for
"Just Cause," which shall mean (i) an act or acts of fraud or dishonesty by you
which results in the personal enrichment of

you or another person or entity at the expense of the Company; (ii) your
admission, confession or conviction of (X) any felony (other than third degree
vehicular infractions), or (Y) of any other crime or offense involving misuse or
misappropriation of money or other property; (iii) your continued material
breach of any obligations under this Agreement 30 days after the Company has
given you notice thereof in reasonable detail, if such breach has not been cured
by you during such period; or (iv) your gross negligence or willful misconduct
with respect to your duties or gross misfeasance of office.

            (d) This Agreement shall terminate immediately upon the Company's
sending you written notice terminating your employment hereunder (without Just
Cause therefor having been given by you) for any reason or for no reason. In the
event of any termination of this Agreement pursuant to this Section 9(d), or in
the event the Company gives you notice pursuant to Section 1(b) of its intention
not to renew this Agreement, the Company's sole obligation to you shall be (i)

                           CHANGE IN CONTROL AGREEMENT

            AGREEMENT, made as of this 2nd day of December, 1999, by and between
Microwave Power Devices, Inc., a Delaware corporation (the "Company"), and
Alfred Weber, the Chairman of the Board, President and Chief Executive Officer
of the Company (the "Executive").

                              W I T N E S S E T H:

            WHEREAS, the Company believes that the establishment and maintenance
of a sound and vital management of the Company is essential to the protection
and enhancement of the interests of the Company and its stockholders;

            WHEREAS, the Company also recognizes that the possibility of a
Change in Control of the Company (as defined in Section 1 hereof), with the
attendant uncertainties and risks, might result in the departure or distraction
of key employees of the Company to the detriment of the Company; and

            WHEREAS, the Company has determined that it is appropriate to take
steps to induce key employees to remain with the Company, and to reinforce and
encourage their continued attention and dedication, when faced with the
possibility of a Change in Control of the Company.

            NOW, THEREFORE, in consideration of the premises and mutual
covenants herein contained, the parties hereto hereby agree as follows:

            1. Change in Control Definition. A Change in Control shall mean the
occurrence of any of the following: (i) any person (as defined in Section
3(a)(9) of the Securities Exchange Act of 1934, as amended (the "Exchange Act")
and as used in Sections 13(d) and 14(d)

<PAGE>

thereof), excluding the Company, any Affiliates (as hereinafter defined) of the
Company, or any employee benefit plan sponsored or maintained by the Company or
its Affiliates (including any trustee of any such plan acting in his capacity as
trustee), becoming the "beneficial owner" (as defined in Rule 13d-3 under the
Exchange Act) of securities of the Company representing more than fifty percent
(50%) of the total combined voting power of the Company's then outstanding
securities; (ii) the merger, consolidation or other business combination of the
Company (a "Transaction"), other than a Transaction involving only the Company's
Affiliates or a Transaction immediately following which the stockholders of the
Company immediately prior to the Transaction continue to have a majority of the
voting power in the resulting entity; (iii) during any period of three (3)
consecutive years beginning on or after the date hereof, the persons who were
members of the Board of Directors of the Company (the "Board") immediately
before the beginning of such period (the "Incumbent Directors") ceasing (for any
reason other than death) to constitute at least a majority of the Board or the
board of directors of any successor to the Company, provided that, any director
who was not a director as of the date hereof shall be deemed to be an Incumbent
Director if such director was elected to the board of directors by, or on the
recommendation of or with the approval of, at least two-thirds of the directors
who then qualified as Incumbent Directors either actually or by prior operation
of the foregoing unless such election, recommendation or approval occurs as a
result of an actual or threatened election contest (as such terms are used in
Rule 14a-11 of Regulation 14A promulgated under the Exchange Act or any
successor provision) or other actual or threatened solicitation of proxies or
contests by or on behalf of a person other than a member of the Board; or (iv)
the approval by the stockholders of the Company of any plan of complete
liquidation of the Company or an agreement for the sale of all or substantially
all of the Company's assets, other than the sale of all or substantially all of
the

                                       2
<PAGE>

assets of the Company to any of the Company's Affiliates. Only one Change in
Control may occur under this Agreement. For purposes of this Agreement, the term
"Affiliates" shall have the same meaning as set forth under the definition of
"affiliates" in Rule 405 of the Securities Act of 1933, as amended.

            2. Term. This Agreement shall commence on the date hereof and shall
expire on the earlier of (i) three (3) years from the date hereof, or (ii) the
date of the death of the Executive, or (iii) the termination of the Executive's
employment with the Company (for any reason) prior to a Change of Control.

            3. Effect of a Change in Control. If a Change in Control occurs
simultaneous with or prior to the expiration of this Agreement pursuant to
Section 2 hereof, then the Executive shall be entitled to the amounts and
benefits provided under Section 4 hereof regardless of whether or not, upon or
after a Change of Control, the Executive continues to be employed with the
Company. In the event the Executive continues to be employed with the Company
upon or after a Change in Control, any and all amounts and benefits provided to
the Executive under Section 4 hereof shall be in addition to, and not in lieu
of, any and all salary, amounts and benefits that Executive receives from the
Company in respect of such continued employment.

            4. Payments upon a Change in Control. If pursuant to Section 3
above, the Executive is entitled to amounts and benefits under this Section 4,
the Company shall pay or provide, as the case may be, the following items:

            (a) within five (5) business days following a Change of Control, the
Company shall pay to the Executive in a lump sum an amount equal to two (2)
times the sum of (i) the

                                       3
<PAGE>

Executive's then current annual salary plus (ii) the Executive's then current
annual targeted bonus pursuant to the terms of that certain Executive Incentive
Bonus Plan of the Company (as such plan may be modified from time to time.)

            (b) upon the occurrence of a Change in Control, all outstanding
stock options granted by the Company to the Executive under the Company's stock
option plans (collectively, the "Plan") shall immediately vest and be
exercisable notwithstanding any provisions of the Plan to the contrary.

            (c) within five (5) business days (or at such earlier time as
required by applicable law) following his termination of employment with the
Company, the Company shall pay to the Executive in a lump sum: (i) any earned
but unpaid base salary, (ii) any earned but unpaid bonus, (iii) accrued but
unused vacation time as of the date of termination, and (iv) incurred but
unreimbursed business expenses for the period prior to termination.

            (d) for a period of twenty-four (24) months commencing on the date
of the Change of Control, subject to the Executive's continued copayment of
premiums which shall not exceed the level of copayments prior to such Change of
Control, the Company shall continue to pay the premiums to provide health
benefits and coverage for the Executive and his dependents under the Company's
health plans in effect prior to such Change of Control which cover senior
executives. The Company's obligation to pay premiums hereunder shall cease upon
the Executive's employment with any employer (other than due to self-employment)
following a Change of Control. Upon the expiration of such twenty-four (24)
month period, the Company shall offer COBRA continuation health coverage to the
Executive and his dependents in accordance with applicable law.

                                       4
<PAGE>

            5. No Duty to Mitigate/Set-off; Terminate Employment Agreement;
Severance. If pursuant to Section 4 hereof the Executive is entitled to payment,
the Executive will not be required to seek other employment or to attempt in any
way to reduce any amounts payable to the Executive by the Company pursuant to
this Agreement. Further, the amounts and benefits provided for in this Agreement
shall not be reduced by any compensation earned by the Executive or benefits
provided to the Executive as the result of employment by another employer or
otherwise. Notwithstanding anything herein to the contrary, if pursuant to
Section 4 hereof the Executive is entitled to payment: (i) the Executive's
Employment Agreement with the Company shall immediately terminate and the
Executive shall not be entitled to any payment with respect to such Employment
Agreement and (ii) the payment pursuant to Section 4 hereof shall be in lieu of
any other severance payments to which Executive may be entitled pursuant to any
severance plan of the Company or otherwise.

            6. Successors; Binding Agreement. In addition to any obligations
imposed by law upon any successor to the Company, the Company 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
Company to expressly assume and agree in writing to perform this Agreement in
the same manner and to the same extent that the Company would be required to
perform it. This Agreement shall inure to the benefit of and be enforceable by
the Executive's personal or legal representatives, executors, administrators,
successors, heirs, distributees, devisees and legatees. If the Executive shall
die while any amount would still be payable to the Executive hereunder if the
Executive had continued to live, all such amounts, unless otherwise provided
herein, shall be paid in accordance with the terms of this Agreement to the
executors,

                                        5
<PAGE>

personal representatives or administrators of the Executive's estate. This
Agreement is personal to the Executive and neither this Agreement or any rights
hereunder may be assigned by the Executive.

            7. Miscellaneous. No provisions of this Agreement may be modified,
waived or discharged unless such waiver, modification or discharge is agreed to
in writing and signed by the Executive 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 shall be deemed a waiver of similar or dissimilar provisions or
conditions at the same or at any prior or subsequent time. This Agreement
constitutes the entire Agreement between the parties hereto pertaining to the
subject matter hereof. 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. All references
to any law shall be deemed also to refer to any successor provisions to such
laws. 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. If any provisions of this Agreement shall be declared
to be invalid or unenforceable, in whole or in part, such invalidity or
unenforceability shall not affect the remaining provisions hereof which shall
remain in full force and effect.

            8. Notices. All notices under this Agreement shall be given in
writing and shall be either delivered personally or sent by certified or
registered mail, return receipt requested, addressed to the other party at the
appropriate address first set forth above, or to such other address as such
party shall designate by written notice as aforesaid. Notices shall be deemed
given when received or two (2) days after mailing, whichever is earlier.
