otherwise transfer (a "Transfer") any interest in any Securities, either
voluntarily or involuntarily, by operation of law or otherwise, except:

                  (a) in the case of any NCCC Stockholder or any HI Stockholder

permitted in accordance with the Other Stockholder Agreements, provided,
however, that each NCCC Stockholder and HI Stockholder shall have the right, but

Stockholder Agreements to purchase any Offered Shares (as defined in the Other

number of Common Shares (i) issued to such NCCC Stockholder or HI Stockholder,
and (ii) issuable upon exercise of any NCCC Warrants or HI Warrants held by such

no event shall shares be Transferred to a Third Party without the prior written
consent of the NCCC Stockholders and the HI Stockholders; or

                  (c) pursuant to a Public Sale or an Approved Sale or to the

provided that (x) the restrictions contained in this Section 2 will continue to
be applicable to the Securities after any Transfer pursuant to clauses (a) and
(b) above, and (y) the transferee of such Securities pursuant to clause (x)
above shall either be a party hereto or shall have executed and delivered to the
Company an Instrument of Accession.

                  2.2. Right of First Offer. If any NCCC Stockholder or any HI
Stockholder desires to sell any interest in any Securities to any Person other
than an Affiliate (other than a Person who is an individual), then such holder
must first notify the Company of such proposed sale (the "Transfer Notice"),
offering the Company the right to purchase such Securities and stating the
aggregate purchase price for which such Securities are being offered and any
other terms of the offer. For 30 days following delivery of the Transfer Notice,
the Company shall have the right to elect to purchase such Securities, at the
price and on other terms stated in the


<PAGE>   7

Transfer Notice. If the Company desires to make such purchase, the Company shall
notify such NCCC Stockholder or such HI Stockholder, as the case may be, within
such 30-day period. Any such purchase shall occur within 60 days after delivery
of the applicable Transfer Notice. If the Company elects not to purchase such
Securities, or fails to make an affirmative election within such 30-day period,
such NCCC Stockholder or such HI Stockholder, as the case may be, shall
thereafter by free to sell such Securities to any other Person so long as (a)
the purchase price is equal to or greater than the purchase price set forth in
the Transfer Notice, (b) the terms of the sale are not materially more favorable
to the purchaser thereof than the terms set forth in the Transfer Notice, and
(c) the purchase occurs within 180 days after the delivery of the applicable
Transfer Notice.

                  2.3. Right of Co-Sale. In the event that the Management
Stockholders (together with their Affiliates) desire to Transfer, either
individually or in the aggregate and whether in a single transaction or a series
of related transactions, ten percent (10%) or more of the shares of Common Stock
which the Management Stockholders collectively own (other than to any Affiliates
or Permitted Transferee of such Management Stockholders that agree to be bound
by the terms of this Agreement) (the Management Stockholders participating in
such Transfer, the "Transferring Stockholders"), the Transferring Stockholders
shall notify each of the NCCC Stockholders and the HI Stockholders, in writing,
of such Transfer and its terms and conditions. Within fifteen (15) days of
receipt of such notice, each of the NCCC Stockholders and the HI Stockholders
shall notify the Transferring Stockholders if such Person elects to participate
in such Transfer. Each such NCCC Stockholder and HI Stockholder that so notifies
the Transferring Stockholders shall have the right to sell, at the same price
the number of shares of Common Stock the third party actually proposed to
purchase multiplied by a fraction, the numerator of which shall be the number of
shares of Common Stock issued and owned by such NCCC Stockholder or HI
Stockholder and the denominator of which shall be the aggregate number of shares
of Common Stock issued and owned by the Transferring Stockholders and each of
the NCCC Stockholders and HI Stockholders exercising his or its rights under
this Section 2.3. If an NCCC Stockholder or HI Stockholder so elects to have his
or its shares sold together with the Transferring Stockholders' shares, then it
shall be a condition to the consummation of the sale by the Transferring
Stockholders to such third party that such shares of such NCCC Stockholder or HI
Stockholder be sold simultaneously with those of the Transferring Stockholders.
The rights under this Section 2.3 shall terminate when the Management
Stockholders own five percent (5%) or less of the outstanding Common Stock.

                  2.4 Transfers of Securities in Breach of this Agreement In the
event of any Transfer of Securities in breach of this Agreement, commencing
immediately upon the date of such attempted Transfer (a) such Transfer shall be
void and of no effect, (b) no dividend of any kind or any distribution pursuant
to any liquidation, redemption or otherwise shall be paid by the Company to the
purported transferee in respect of such Securities (all such rights to payment
by the transferring Stockholder and/or the purported transferee being deemed
waived), (c) the voting rights of such Securities, if any, shall terminate, and
(d) neither the transferring Stockholder nor the purported transferee shall be
entitled to exercise any rights with respect to such Securities until such
Transfer in breach of this Agreement has been rescinded.

                  2.5. Classes of Securities. Notwithstanding anything herein to
the contrary, for purposes of this Section 2, all classes of Common Stock shall
be treated as a single class and the Common Stock and the Preferred Stock shall
be treated as separate classes.

                  ss.3. SALE OF THE COMPANY.

                  3.1. Approved Sale. In the event the sale of the Company
(whether by merger, consolidation, sale of all or substantially all of the
Company's assets or sale of all or substantially all of the outstanding shares
of Common Stock) is approved by the Company's Board of Directors and consented
to by the HI Stockholders and the NCCC Stockholders (an "Approved Sale"), each
Stockholder hereby waives, to the extent permitted by applicable law, all rights
to object to or dissent from such Approved Sale and hereby agrees to consent to
and raise no objections against such Approved Sale; provided that such sale is
not to an Affiliate of any other Stockholder. If the NCCC Stockholders or the HI
Stockholders do not consent to any such proposed sale, the Company, at the
Company's expense, may retain the services of an independent investment banking
firm that (i) is nationally or regionally recognized, (ii) is one of three
investment banking firms approved by the HI Stockholders and the NCCC
Stockholders, (iii) is not an Affiliate of the HI Stockholders and the NCCC
Stockholders, and (iv) has a net worth, determined in accordance with generally
accepted accounting principles, of at least $25,000,000, to appraise the
fairness of such proposed sale. If that independent investment banking firm
executes and delivers to the NCCC Stockholders and the HI Stockholders a
fairness opinion, in form and substance satisfactory to the NCCC Stockholders
and the HI Stockholders, stating that the price and other terms of such proposed
sale are fair, then such proposed sale shall be deemed an Approved Sale.

                  3.2. Obligation of Stockholders. The Company and the
Stockholders hereby agree to cooperate fully in any Approved Sale and not to
take any action prejudicial to or inconsistent with such Approved Sale. Without
limiting the generality of the foregoing, each Stockholder hereby agrees to (i)
vote such Stockholder's Securities to approve the terms of any such Approved
Sale and such matters ancillary thereto as may be necessary in the judgment of
the Board of Directors of the Company to effect such Approved Sale, (ii) waive
any appraisal rights that such Stockholder would have with respect to such
Approved Sale, (iii) in an Approved Sale structured as a sale of stock, sell all
of such Stockholder's Securities on the terms and conditions approved by the
Board of Directors of the Company and (iv) upon request, deliver such
Stockholder's Securities (together with executed instruments of transfer) in
escrow (pending receipt of the purchase price therefor) to counsel for the
Company in such sale.

                  3.3. Received Consideration. The obligations of the
Stockholders with respect to any Approved Sale are subject to the satisfaction
of the condition that upon the consummation of such sale, all of the sellers of
Common Stock and Preferred Stock, respectively, will receive the same form and
amount of consideration per share of Common Stock and Preferred Stock, as
applicable, or if any such sellers are given an option as to the form and amount
of consideration to be received per share of Common Stock or Preferred Stock,
all holders of Common Stock and Preferred Stock, as applicable, will be given
the same option and all of the sellers of Securities exercisable for Common
Stock and Preferred Stock will receive the same form and amount of




<PAGE>   9

consideration and the same options as to form and amount of consideration,
referred to above, in each case per share of Common Stock and Preferred Stock,
as the case may be, less the exercise price per share of Common Stock or
Preferred Stock, as the case may be. It shall be a condition to any Approved
Sale structured as a stock sale that the purchaser with respect to such
transaction contemporaneously purchase or cause to be redeemed all of the
outstanding Preferred Stock for a price per share equal to the Liquidation Value
(as defined in the Charter), plus all accrued and unpaid dividends thereon.

                  3.4. Proxy. Each Stockholder hereby appoints NCCC in any
Approved Sale as such Stockholder's true and lawful proxy and attorney, with
full power of substitution, to vote all Securities owned by such Stockholder or
over which such Stockholder has voting control to effectuate the agreements set
forth in this Section 3, but only in the event of and to the extent necessary to
remedy any breach by such Stockholder of its obligations under this Section 3.
The proxies and powers granted by each Stockholder pursuant to this Section 3.4
are coupled with an interest and are given to secure the performance of such
Stockholder's duties under this Section 3. Such proxies are irrevocable for so
long as this Section 3 remains in effect and will survive the death,
incompetency or disability of any Stockholder who is an individual and the
merger, liquidation or dissolution of any Stockholder that is a corporation,
partnership or other entity.

                  ss.4. BOARD OF DIRECTORS.

                  Each of the Stockholders agrees as follows:

                           (iii) One individual designated by NCCC, so long as
                  NCCC holds any Securities.

                  ss.5. ADDITIONAL LEGEND. So long as any Securities are subject
to the provisions hereof, all certificates or instruments representing
Securities will have imprinted on them the following legend:

                  The shares represented by this certificate are subject to the
                  terms of a certain Stockholder Agreement, dated as of July 23,
                  1996, among the issuer of this certificate and certain
                  stockholders. The Stockholder Agreement contains certain
                  restrictive provisions relating to the voting (including the
                  grant of an irrevocable proxy relative to voting matters) and
                  transfer of shares of the stock represented hereby. A copy of
                  the Stockholder Agreement is on file at the Company's
                  principal offices. Upon written request to the Company's
                  Secretary, a copy of the Stockholder Agreement will be
                  provided without charge to appropriately interested persons.

                  ss.6. SEVERABILITY. Whenever possible, each provision of this
Agreement will be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Agreement is held to be invalid,
illegal or unenforceable in any respect under any applicable law or rule in any
jurisdiction, such invalidity, illegality or unenforceability will not affect
any other provision or any other jurisdiction, but this Agreement will be
reformed, construed and enforced in such jurisdiction as if such invalid.
illegal or unenforceable provision had never been contained herein.

                  ss.7. ENTIRE AGREEMENT. Except as otherwise expressly set
forth herein, this document embodies the complete agreement and understanding
among the parties hereto with respect to the subject matter hereof and thereof
and supersedes and preempts any prior understandings, agreements or
representations by or among the parties, written or oral, which may have related
to the subject matter hereof in any way.

                  ss.8. SUCCESSORS AND ASSIGNS. This Agreement will bind and
inure to the benefit of and be enforceable by the Company and the Stockholders
and their respective heirs, successors and assigns.

                  ss.9. COUNTERPARTS. This Agreement may be executed in separate
counterparts each of which will be an original and all of which taken together
will constitute one and the same agreement.

                  ss.10. REMEDIES. The Stockholders will be entitled to enforce
their rights under this Agreement specifically (without posting a bond or other
security), to recover damages by reason of any breach of any provision of this
Agreement and to exercise all other rights existing in their favor. The parties
hereto agree and acknowledge that money damages may not be an adequate remedy
for any breach of the provisions of this Agreement and that any Stockholder may
in its sole discretion apply to any court of law or equity of competent
jurisdiction for specific performance and/or injunctive relief in order to
enforce or prevent any violation of the provisions of this Agreement. In the
event of any dispute involving the terms of this Agreement, the prevailing party
shall be entitled to collect reasonable fees and expenses incurred by the
prevailing party in connection with such dispute from the other parties to such
dispute.

                  ss.11. NOTICES. Any notice provided for in this Agreement will
be in writing and will be deemed properly delivered if either personally
delivered or sent by telecopier, overnight courier or mailed certified or
registered mail, return receipt requested, postage prepaid to the recipient (a)
if to any Stockholder, at the address listed for such Stockholder in the stock
records of the Company and (b) if to the Company, to it at Microwave Components

waiver of any provision of this Agreement will be effective against the Company

writing by the Majority Investor Holders, HI, NCCC and the holders of at least
fifty-one percent (51%) of the total number of then outstanding shares of Common
Stock constituting Securities then held by all Stockholders; provided, however,
that no amendment, modification or waiver of any provision of this Agreement
that adversely affects the rights of one particular Party (as hereinafter
defined) to this Agreement in a manner different from the rights of the other
Parties shall be effective against such adversely affected Party unless approved
in writing by the holders of at least a majority of the outstanding shares of
Common Stock constituting Securities then held by all members of such Party. As
used in this Section 12, the term "Party" means any one of the following
entities or groups: (a) the Company, (ii) the HI Stockholders, (iii) the NCCC
Stockholders and (iv) the



<PAGE>   13

this Agreement will in no way be construed as a waiver of such provisions and
will not affect the right of such party thereafter to enforce each and every
provision of this Agreement in accordance with its terms.

earliest to occur of (a) the completion of any voluntary or involuntary
liquidation or dissolution of the Company, (b) the completion of a Qualified
Public Offering, (c) the sale of all or substantially all of the Company's
assets or of a majority of the outstanding Common Stock to a third party
(whether pursuant to a merger, consolidation or otherwise) in accordance with
the terms hereof or (d) a DeMinimus Holding Event. As used in this Section 13, a
"DeMinimus Holding Event" means that the aggregate sum of (i) the number of
shares of any Common Stock owned by the HI Stockholders and the NCCC
Stockholders, plus (ii) the number of shares of Common Stock issuable upon the
exercise of any warrant or warrants owned by the HI Stockholders and the NCCC
Stockholders, is less than one percent (1%) of the then issued and outstanding
shares of Common Stock.

                  SS.14. GOVERNING LAW. ALL QUESTIONS CONCERNING THE
CONSTRUCTION, VALIDITY AND INTERPRETATION OF THIS AGREEMENT WILL BE GOVERNED BY
AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF OHIO, WITHOUT REGARD
TO PRINCIPLES OF CONFLICTS OF LAW.

                  ss.15. DESCRIPTIVE HEADINGS. The descriptive headings of this
Agreement are inserted for convenience only and do not constitute a part of this
Agreement.

                  ss.16. CONSTRUCTION. The language used in this Agreement will
be deemed to be the language chosen by the parties to express their mutual
intent, and no rule of strict construction will be applied against any party.

                  ss. 17. WARRANT AGREEMENT. This Agreement, and HI's and NCCC's
being a party to this Agreement, shall in no way be construed as a waiver of, or
an amendment, supplement or other modification of, any provision of any of the
Financing Documents (as defined in the Purchase Agreement).
