                         LIBERTYVILLE, ILLINOIS 60048
 
                                                                   May 21, 1998
 
Dear Shareholder:
 
  You are cordially invited to attend the Special Meeting of the shareholders
of Corcom, Inc., an Illinois corporation ("Corcom") to be held at the offices
of D'Ancona & Pflaum, 30 North La Salle Street, 27th Floor, Chicago, Illinois,
at 10:00 a.m. local time, on June 18, 1998.
 
  At this important meeting, you will be asked to consider and vote upon a
proposed merger of RF Acquisition Corp., a wholly owned subsidiary of
Communications Instruments, Inc., with and into Corcom. In the proposed
merger, Corcom will become a wholly owned subsidiary of Communications
Instruments and holders of Corcom common stock will be entitled to receive
$13.00 in cash for each share of their Corcom common stock. The enclosed Proxy
Statement provides a detailed description of the matters to be considered at
the Special Meeting and information concerning Corcom and the proposed merger.
 
  Consummation of the merger is subject to a number of conditions, including
Communications Instruments obtaining necessary financing. Accordingly, even if
the shareholders approve the merger, there can be no assurance that the merger
will be consummated.
 
  James A. Steinback, a Director of Corcom, and I have entered into a voting
agreement with Communications Instruments under which Communications
Instruments has the power, upon the occurrence of certain conditions, to vote
our 1,198,399 shares or 31.3% of Corcom's common stock in favor of the merger.
 
  ABN AMRO Incorporated ("ABN AMRO"), Corcom's financial advisor, has rendered
an opinion to the Board of Directors of Corcom, to the effect that, as of the
date of the merger agreement (March 10, 1998) the consideration to be paid for
the Corcom common stock was fair from a financial point of view to Corcom's
shareholders. A copy of such opinion, which sets forth the assumptions made,
matters considered and limitations on the review undertaken by ABN AMRO,
appears as Appendix B to the Proxy Statement.
 
  AFTER CAREFUL CONSIDERATION, YOUR BOARD OF DIRECTORS HAS UNANIMOUSLY
APPROVED THE MERGER AND UNANIMOUSLY RECOMMENDS THAT YOU VOTE FOR THE PROPOSAL
PRESENTED AT THE SPECIAL MEETING.
 
  YOUR FAILURE TO RETURN A PROXY OR TO ATTEND THE SPECIAL MEETING IN PERSON
WILL HAVE THE EFFECT OF A VOTE AGAINST THE MERGER. YOU ARE THEREFORE
ENCOURAGED TO SIGN AND RETURN THE ENCLOSED PROXY.
 
  It is important that your shares be present at the Special Meeting,
regardless of the number of shares of common stock you hold. Therefore, please
sign, date and return your proxy card as soon as possible, whether or not you
plan to attend. This will not prevent you from voting your shares in person if
you subsequently choose to attend. As soon as practicable after the
effectiveness of the merger, you will receive instructions for surrendering
your Corcom share certificates (in exchange for $13.00 in cash) and a letter
of transmittal to be used for this purpose. You should not submit your share
certificates for exchange until you have received such instructions and the
letter of transmittal.
 
                                          Sincerely yours,
 
                                          /s/ Werner E. Neuman
                                          Werner E. Neuman

                                      FOR
                        SPECIAL MEETING OF SHAREHOLDERS
                           TO BE HELD JUNE 18, 1998
 
                               ----------------
 
  This Proxy Statement is furnished to shareholders of Corcom, Inc., an
Illinois corporation ("Corcom" or the "Company"), in connection with the
solicitation of proxies by the Board of Directors of the Company for use at
the special meeting of shareholders to be held on June 18, 1998 (the "Special
Meeting"), and at any and all adjournments or postponements thereof. Proxies
in the form enclosed will be voted at the Special Meeting, if properly
executed, returned to the Company prior to the meeting and not revoked. The
proxy may be revoked at any time before it is voted by notifying the Company,
there being no formal procedure required. This Proxy Statement and the
enclosed proxy card are first being mailed to shareholders of the Company on
or about May 22, 1998.
 
  At the Special Meeting, holders of the Company's common stock will be asked
to consider and vote upon a proposal to approve and adopt an Agreement and
Plan of Merger, dated March 10, 1998 (the "Merger Agreement"), among the
Company, Communications Instruments, Inc., a North Carolina corporation
("CII") and RF Acquisition Corp., an Illinois corporation and a wholly owned
subsidiary of CII ("Merger Subsidiary"), pursuant to which (i) Merger
Subsidiary will be merged (the "Merger") into the Company and (ii) each share
of common stock of the Company will be converted automatically into the right
to receive $13.00 per share in cash. A copy of the Merger Agreement is
attached as Appendix A to this Proxy Statement.
 
  THE COMPANY'S BOARD OF DIRECTORS HAS DETERMINED THAT THE TERMS OF THE MERGER
AGREEMENT, WHICH WERE ESTABLISHED THROUGH ARM'S-LENGTH BARGAINING WITH CII,
AND THE TRANSACTIONS CONTEMPLATED THEREBY, INCLUDING THE MERGER, ARE FAIR TO,
AND IN THE BEST INTERESTS OF, THE COMPANY'S SHAREHOLDERS. THE COMPANY'S BOARD
OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE SHAREHOLDERS VOTE "FOR" THE
APPROVAL OF THE MERGER AGREEMENT. FOR A DESCRIPTION OF CERTAIN CONFLICTS OF
INTERESTS OF THE COMPANY'S PRESIDENT, WERNER E. NEUMAN, IN APPROVING THE
MERGER AGREEMENT SEE "SPECIAL FACTORS--INTERESTS OF CERTAIN PERSONS IN THE
MERGER."
 
  YOUR FAILURE TO RETURN A PROXY OR TO ATTEND THE SPECIAL MEETING IN PERSON
WILL HAVE THE EFFECT OF A VOTE AGAINST THE MERGER. YOU ARE THEREFORE
ENCOURAGED TO SIGN AND RETURN THE ENCLOSED PROXY.
 
  Only holders of record of common stock at the close of business on May 4,
1998 (the "Record Date") are entitled to notice of, and to vote at, the
Special Meeting. At the close of business on the Record Date, the Company had
issued and outstanding, and entitled to vote at the Special Meeting 3,921,543
shares of common stock.
 
  Approval and adoption of the Merger Agreement requires the affirmative vote
of the holders of record of at least two-thirds of the outstanding shares of
common stock. Where shareholders have appropriately specified how their
proxies are to be voted, they will be voted accordingly. Abstentions and
broker non-votes will have the same effect as votes against the approval of
the Merger Agreement.
<PAGE>
 
  As a condition precedent of CII's offer to acquire the Company, Werner E.
Neuman, the Company's President, and James A. Steinback, a Director of the
Company, have entered into a voting agreement with Merger Subsidiary. Under the
terms of the voting agreement, Messrs. Neuman and Steinback granted to Merger
Subsidiary a proxy to vote their shares at the Special Meeting for the approval
of the Merger Agreement, effective only upon the occurrence of certain
conditions. No consideration was paid to CII nor Messrs. Neuman and Steinback
in connection with entering into the voting agreement. Other than the voting
agreement and the Merger Agreement, there are no affiliations between the
Company, its management and respective subsidiaries and CII, its management and
respective subsidiaries. As a result of this voting agreement, Merger
Subsidiary may have the power to vote 1,198,399 shares or 31.3% of the
Company's outstanding shares of common stock for approval of the Merger
Agreement.
 
  Holders of shares of the Company's common stock have the right to dissent
from the Merger and to demand appraisal of, and payment for, their shares by
following the procedures set forth in Sections 11.65 and 11.70 of the Business
Corporation Act of the State of Illinois, a copy of which sections are attached
hereto as Appendix C and summarized under "Special Factors--Dissenter's Rights"
and "The Merger--Appraisal Rights of Dissenting Shareholders" in the
accompanying Proxy Statement.
 
  Consummating the Merger is subject to a number of additional conditions,
including CII obtaining the necessary financing. Accordingly, even if
shareholders approve the Merger, there can be no assurance that the Merger will
be consummated.
 
  Each properly executed proxy returned to the Company prior to the Meeting
will be voted, unless the shareholder otherwise specifies in the proxy, (i) for
approval of the Merger Agreement and (ii) at the discretion of the proxy
holders on any other matter that may properly come before the meeting or any
adjournment thereof. Where shareholders have appropriately specified how their
proxies are to be voted, they will be voted accordingly. If any other matter or
business is brought before the Special Meeting, the proxy holders may vote the
proxies in their discretion. The directors do not know of any such other matter
or business.

EXCHANGE COMMISSION NOR HAS THE COMMISSION PASSED UPON THE FAIRNESS OR MERITS
OF SUCH TRANSACTION NOR UPON THE ACCURACY OR ADEQUACY OF THE INFORMATION
CONTAINED IN THIS DOCUMENT. ANY REPRESENTATION TO THE CONTRARY IS UNLAWFUL.
 
                              CAUTIONARY STATEMENT

PARTIES TO THE MERGER
 
  The Company. The Company's business consists of the design, manufacture, and
sale of radio frequency interference filters to the commercial, facility, and
military filter markets. The Company also manufactures and sells a broad line
of power entry devices that are used to connect electronic equipment to an
external power source.
 
  Radio frequency interference ("RFI") filters are electronic components used
to protect electronic equipment from radio frequency interference conducted
through the AC power cord. They are also used to control the emission of the
RFI generated by electronic equipment so these emissions do not interfere with
other electronic devices. Customers purchase RFI filters for emission control
purposes to bring their equipment into compliance with government regulations
that limit the amount of radio frequency interference that can be emitted by
digital computing devices. The Company also manufactures a complete line of
Signal Sentry products, which are filtered modular RJ jacks designed to solve
RFI problems on signal lines. The Company maintains a catalog of standard
commercial filters that contains approximately 500 designs, offering a variety
of sizes, electrical configurations, current ratings and environmental
capabilities. All of the Company's products are marketed under its federally
registered trademark, "CORCOM".
 
  The Company's principal executive offices are located at 844 East Rockland
Road, Libertyville, Illinois, 60048, and its telephone number is (847) 680-
7400.
 
  CII. CII is a leading designer, manufacturer and marketer of a broad line of
high performance relays and solenoids. Relays, which are switches used to
control electric current in a circuit, and solenoids, which convert electric
signals into mechanical motion, are critical components for a wide range of
commercial, industrial and electronic products. CII focuses on producing
highly engineered relays and solenoids for customized niche applications that
demand reliable performance, small size, light weight, low energy consumption
and durability. CII's products are used in a large number of diverse end-use
applications including commercial aircraft, defense electronics,
telecommunication equipment, satellites, medical products and HVAC systems.
CII is owned by Code Hennessy & Simmons LLC ("CHS") and certain members of
CII's management. CHS is a Chicago-based private investment firm with more
than $500 million of committed equity capital under management. CHS invests
primarily in middle-market companies that design, manufacture and distribute a
broad array of consumer and industrial products.
 
  Merger Subsidiary. Merger Subsidiary was recently formed by CII for
effecting the Merger and has not conducted any prior business. Merger
Subsidiary's principal executive offices are located at the offices of CII.
See "Certain Information Regarding CII, Merger Subsidiary and Affiliates."
 
SPECIAL MEETING
 
  Place and Purpose. The Special Meeting of the shareholders of the Company
will be held at the offices of D'Ancona & Pflaum, 30 North La Salle Street,
27th Floor, Chicago, Illinois, at 10:00 a.m. local time, on June 18, 1998. At
the Special Meeting, the Company's shareholders will be asked to consider and
vote upon the approval and adoption of the Merger Agreement attached hereto as
Appendix A.
 
  Record Date; Quorum. Only shareholders of record of the Company at the close
of business on the Record Date will be entitled to notice of, and to vote at,
the Special Meeting. On the Record Date, there were 3,921,543 shares of the
Company's common stock outstanding and entitled to vote at the Special
Meeting. Each holder of
 
                                       1
<PAGE>
 
shares of the Company's common stock is entitled to one vote for each such
share so held, exercisable in person or by properly executed and delivered
proxy, at the Special Meeting. The presence of the holders of at least a
majority of the shares of the Company's common stock outstanding on the Record
Date, whether present in person or by properly executed and delivered proxy,
will constitute a quorum for purposes of the Special Meeting.
 
  Vote Required. The affirmative vote of the holders of record of at least
two-thirds of the outstanding shares of the Company's common stock entitled to
vote at the Special Meeting is necessary to approve and adopt the Merger
Agreement. Where shareholders have appropriately specified how their proxies
are to be voted, they will be voted accordingly. Abstentions and broker non-
votes will be counted toward determining whether a quorum is present at the
Special Meeting. Abstentions on the Merger and broker non-votes will have the
same effect as votes against approval of the Merger.
 
  As a condition precedent of CII's to offer to acquire the Company, Werner E.
Neuman, the Company's President, and James A. Steinback, a Director of the
Company, have entered into a voting agreement (the "Voting Agreement") on
March 10, 1998 with Merger Subsidiary. Under the terms of the Voting
Agreement, Messrs. Neuman and Steinback have (i) agreed to vote their
respective shares of common stock in favor of the Merger, and (ii) granted to
Merger Subsidiary a proxy to vote such shares in favor of approving and
adopting the Merger Agreement. The obligations of Messrs. Neuman and Steinback
are effective, however, only upon the occurrence of certain conditions. No
consideration was paid to CII nor Messrs. Neuman and Steinback in connection
with entering into the voting agreement. Other than the voting agreement and
the Merger Agreement, there are no affiliations between the Company, its
management and respective subsidiaries and CII, its management and respective
subsidiaries. See "Special Factors--Voting Agreement."
 
  As a result of the Voting Agreement, Merger Subsidiary may have the power to
vote 1,198,399 shares or 31.3% of the Company's outstanding shares of common
stock for approval of the Merger Agreement.
 
THE MERGER
 
  Pursuant to the Merger, Merger Subsidiary will be merged into the Company
and the Company will become a subsidiary of CII. Upon completion of the
Merger, each share of the Company's common stock will be converted into the
right to receive $13.00 in cash (the "Merger Consideration"). Shares of the
Company's common stock held by shareholders who perfect their appraisal rights
under Illinois law (the "Unconverted Shares") will not be converted into the
Merger Consideration upon completion of the Merger.
 
  As a result of the Merger, the entire equity interest in the Company will be
owned by CII. The shareholders of the Company will no longer have any interest
in, and will not be shareholders of, the Company, and therefore will not
participate in its future earnings and growth. Instead, each such holder of
the Company's common stock will have the right to receive $13.00 in cash,
without interest, for each share held (other than the Unconverted Shares).
Following the Merger, CII will have the sole opportunity to benefit from any
earnings and growth of the Company, and will bear the risk of any decrease in
the Company's value. Following the Merger, the Company's common stock will no
longer be traded on The Nasdaq National Market ("Nasdaq"), price quotations
will no longer be available and the registration of the Company's common stock
under the Securities Exchange Act of 1934, as amended (the "Exchange Act"),
will be terminated.
 
REASONS FOR THE MERGER AND RECOMMENDATION OF THE COMPANY'S BOARD OF DIRECTORS
 
  In reaching its determination to recommend the Merger, the Company's Board
of Directors consulted with the Company's management, as well as its legal and
financial advisors, and considered a number of factors. Among the factors that
the Company's Board of Directors considered were (i) the belief that the
Merger provides the best means for the Company's shareholders to maximize the
value of their holdings; (ii) information relating to the financial
performance, prospects and business operations of the Company; (iii) reports
from management and legal advisors on specific terms of the Merger Agreement;
(iv) the belief that the Merger Agreement does not unreasonably preclude a
third party from proposing an alternative transaction; (v) the opinion of ABM
AMRO Incorporated ("ABN AMRO"), dated March 10, 1998, that the consideration
to be received by holders
 
                                       2
<PAGE>
 
of the Company's common stock is fair to such holders from a financial point
of view; and (vi) the premium the Merger Consideration represents over (A) the
price per share of the Company's common stock on the day immediately before
the meeting of the Board of Directors to approve the Merger Agreement and (B)
the historical trading price of the Company's common stock. See "Special
Factors--Reasons for the Merger and Recommendation of the Company's Board of
Directors."
 
  The Company's Board of Directors has determined that the terms of the Merger
Agreement, which were established through arm's-length bargaining with CII,
and the transactions contemplated thereby, including the Merger, are fair to,
and in the best interests of, the Company's shareholders. ACCORDINGLY, THE
COMPANY'S BOARD OF DIRECTORS HAS UNANIMOUSLY APPROVED THE MERGER AGREEMENT AND
UNANIMOUSLY RECOMMENDS THAT THE COMPANY'S SHAREHOLDERS VOTE FOR APPROVAL AND
ADOPTION OF THE MERGER AGREEMENT. For a description of certain conflicts of
interests of the Company's President, Werner E. Neuman, in approving the
Merger Agreement, see "Special Factors--Interests Of Certain Persons In The
Merger."
 
OPINION OF FINANCIAL ADVISOR
 
  ABN AMRO has delivered its written opinion to the Company's Board of
Directors that, as of March 10, 1998 (the date the Board of Directors approved
the Merger Agreement), the Merger Consideration was fair, from a financial
point of view, to the holders of the Company's common stock. ABN AMRO will be
paid a fee upon consummation of the Merger. See "Special Factors--Opinion of
Financial Advisor."
 
  A copy of ABN AMRO's opinion, which sets forth the assumptions made,
procedures followed, matters considered, limitations on and scope of the
review by ABN AMRO, is attached as Appendix B to this Proxy Statement. The
Company's shareholders are encouraged to read such opinion in its entirety.
See "Special Factors--Opinion of Financial Advisor."
 
EFFECTIVE TIME OF THE MERGER
 
  It is currently contemplated that the Merger will be consummated as soon as
practicable after the Special Meeting and satisfaction of all closing
conditions under the Merger Agreement (including receipt of financing). The
Merger will be effective upon the filing of Articles of Merger with the
Secretary of State of Illinois (the "Effective Time").
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
  In considering the recommendations of the Company's Board of Directors, the
Company shareholders should be aware that certain members of management have
interests in the Merger that are in addition to the interests of the Company
shareholders generally and which may create potential conflicts of interest.
See "Special Factors--Interests of Certain Persons in the Merger."
 
  Consulting and Noncompetition Agreement. A condition to CII's obligations
under the Merger Agreement is that Mr. Neuman execute a two-year consulting
agreement, effective January 1, 1999 (the "Consulting Agreement"). Although
the Consulting Agreement will not be executed until the Effective Time, the
parties have agreed to a form of agreement that was delivered by CII to Mr.
Neuman in connection with the execution of the Merger Agreement. Under the
form of Consulting Agreement agreed to by Mr. Neuman and CII, Mr. Neuman will
provide consulting services to Corcom from time to time for a period of two
years. In consideration of these consulting services and a noncompetition
covenant during the term of the agreement, Mr. Neuman will receive $211,000
per annum, use of a Company owned automobile and health benefits that are no
less favorable to Mr. Neuman than the policies in effect prior to the
Effective Time. The form of Consulting Agreement also contains customary
nonsolicitation covenants and confidentiality provisions.
 
  Change of Control Payment. On November 9, 1988, Mr. Neuman entered into an
employment agreement with the Company, which was amended on September 1, 1990
(the "Neuman Employment Agreement"). Pursuant to the terms of the Neuman
Employment Agreement, Mr. Neuman is employed as President at a minimum
compensation of $150,000 per annum for a term to continue in effect until
terminated by either party on specified written prior notice. Upon a
termination of Mr. Neuman's employment for any reason, other than
 
                                       3
<PAGE>
 
death, subsequent to a "change in control" (as defined in the Neuman
Employment Agreement), Mr. Neuman is entitled to all amounts then due to him
under the agreement and to a lump sum termination payment equal to 250% of the
average of his annual minimum and bonus compensation for services during the
three years preceding such termination of employment. Upon written notice by
Mr. Neuman to the Company that a change in control is intended or contemplated
or shall occur in the future, the Company will be obligated to place in escrow
the amounts necessary to fund the amounts due to Mr. Neuman as described in
the preceding sentence.
 
  The Merger will constitute a "change of control" of the sort contemplated by
the Neuman Employment Agreement. Mr. Neuman has indicated to the Company that
he plans to give notice of intent to terminate his employment with the Company
to be effective on December 31, 1998. Therefore, if the Merger is consummated,
Mr. Neuman will be entitled to a "change of control" payment from the Company.
Under the terms of the Consulting Agreement agreed upon by Mr. Neuman and CII,
Mr. Neuman will accept an amount equal to $850,000 as his "change of control"
payment for purposes of the Neuman Employment Agreement, which will be payable
on December 31, 1998.
 
  Severance Payments. Pursuant to the terms of the Merger Agreement, the
Company is allowed to enter into severance agreements with certain employees
prior to the consummation of the Merger. Under the terms of these severance
agreements, employees shall be entitled to a payment equal to their base
salary and bonus in fiscal 1997 in the event their employment with the Company
is terminated by the Company without "cause" (as defined) at any time prior to
the first anniversary of the Effective Time. The Company plans to enter into
such severance agreements with each of Michael Raleigh (Vice President-
Engineering and Quality Assurance), Fernando Pena (Vice President-
Manufacturing), Oswald Hoffman (Manager-Corcom GmbH), Gary Baltimore (Vice
President-Sales), Joseph Ritter (Vice President-Pacific Region Sales) and
Sherrill Bishop (Vice President-Human Resources).
 
  In addition, Thomas J. Buns, Vice President and Treasurer of the Company,
has an agreement with the Company for his employment. The agreement may be
terminated by either party on six months prior written notice. Upon a
termination of employment for any reason by the Company, other than "cause"
(as defined), or death, subsequent to a "change in control" (as defined), Mr.
Buns shall be entitled to all amounts then due him and to a lump sum
termination payment equal to 100% of the average of his annual minimum and
bonus compensation for services during the year preceding such termination.
Following the Effective Time, if Mr. Buns' employment is terminated by the
Company without cause during the term of his employment agreement, he will be
entitled to such a severance payment. The total of Mr Buns' minimum and bonus
compensation for fiscal 1997 was approximately $204,000.
 
  Treatment of Stock Options. Under the terms of the Merger Agreement, all
outstanding options granted under the Company's existing stock option plans
(the "Option Plans"), whether or not vested or exercisable, will be canceled.
The holders of the options will be entitled to receive (subject to applicable
withholding taxes) an amount in cash equal to the product of (i) the
difference between $13.00 and the exercise price of such options and (ii) the
number of shares of the Company's common stock subject to such options.
Members of the Company's management who own options will receive this option
consideration as a result of the Merger.
 
  Indemnification. The Merger Agreement also provides for certain
indemnification and insurance arrangements for the officers and directors of
the Company. See "The Merger--Indemnification."
 
RIGHTS OF DISSENTING SHAREHOLDERS
 
  Under Illinois law, each shareholder of the Company has dissenters'
appraisal rights provided such shareholder does not vote in favor of the
Merger Agreement and complies with certain statutory procedures within the
time frames specified by the Illinois Business Corporation Act of 1983, as
amended (the "IBCA"). The value determined in such appraisal could be more
than, the same as, or less than the value of the Merger Consideration,
depending upon the results of the statutory appraisal process. Sections 11.65
and 11.70 of the IBCA, which contain the provisions relating to dissenters'
appraisal rights, are set forth on Appendix C to this
 
                                       4
<PAGE>
 
Proxy Statement. IT IS A CONDITION TO CII'S OBLIGATION TO CONSUMMATE THE
MERGER THAT DISSENTERS' APPRAISAL RIGHTS NOT BE PERFECTED WITH RESPECT TO MORE
THAN 5% OF THE OUTSTANDING SHARES OF CORCOM COMMON STOCK. See "The Merger--
Appraisal Rights of Dissenting Shareholders."
 
FEDERAL INCOME TAX CONSEQUENCES
 
  The receipt of cash by a shareholder in exchange for his or her shares of
the Company's common stock pursuant to the Merger or the exercise of
dissenters' rights will, in each case, constitute a taxable transaction to
such shareholder for federal income tax purposes and may also be a taxable
transaction under applicable state, local and foreign tax laws. In general, a
shareholder will recognize gain or loss equal to the difference between $13.00
per share and such shareholder's adjusted tax basis in the shares exchanged.
 
  All shareholders should read carefully the discussion in "Special Factors--
Federal Income Tax Consequences" and other sections of this Proxy Statement.
They are urged to consult their own tax advisors as to the specific
consequences to them of the Merger under federal, state, local and any other
applicable tax laws.
 
ACCOUNTING TREATMENT
 
  The Company understands that the Merger will be accounted for by CII as a
"purchase" under generally accepted accounting principles.
 
FINANCING OF THE MERGER
 
  It is estimated that approximately $44.0 million (net of cash and cash
equivalents of the Company) will be required to consummate the Merger. The
principal source for financing the Merger will be a credit facility with a
senior lender. CII has received a commitment letter from Bank of America
National Trust and Savings Association to provide up to $60 million in senior
secured credit facilities, which will be split between a $25 million revolving
credit and a $35 million term loan. This senior secured credit facility will
be used by CII: (i) to acquire the common stock of the Company in the Merger;
(ii) to refinance up to $7.5 million of CII's existing indebtedness; (iii) to
provide for working capital needs; (iv) for general corporate purposes; and
(v) to pay related fees and expenses. This financing is subject to certain
conditions, including the execution of a definitive credit agreement
satisfactory to Bank of America and there being no material adverse change in
the financial condition, business, operations, properties or prospects of the
Company or CII. See "The Merger--Financing."
 
CONDITIONS TO THE MERGER
 
  Each party's obligation to effect the Merger is subject to the satisfaction
of a number of conditions, most of which may be waived by a specified party or
parties. The most significant conditions to consummating the Merger include
(i) obtaining the vote of holders of two-thirds of the outstanding shares of
the Company's common stock, (ii) obtaining all consents and approvals, (iii)
CII receiving the debt financing contemplated by the commitment provided to
CII, a copy of which have been delivered to the Company's Board of Directors,
(iv) the representations and warranties of the parties being true and correct
in all material respects as of the Effective Time of the Merger except for
certain changes that are specifically permitted, and (v) holders of no more
than 5% of the Company's common stock having perfected their dissenters'
rights. See "The Merger--Conditions to Merger."
 
  EVEN IF THE SHAREHOLDERS APPROVE THE MERGER, THERE CAN BE NO ASSURANCE THAT
THE MERGER WILL BE CONSUMMATED.
 
NO SOLICITATION
 
  The Merger Agreement provides that neither the Company nor any of its
representatives will directly or indirectly (i) solicit, initiate, facilitate
or encourage any inquiries or the making of any proposal with respect to
 
                                       5
<PAGE>
 
any "Acquisition Transaction" (as defined below), or (ii) negotiate or
otherwise engage in substantive discussions with any person (other than Merger
Subsidiary or CII) with respect to any Acquisition Transaction or enter into
any agreement, arrangement or understanding requiring it to abandon, terminate
or fail to consummate the Merger or any other transactions contemplated by the
Merger Agreement. The Merger Agreement defines the term "Acquisition
Transaction" as any of the following transactions (other than the Merger)
involving the Company or any of its subsidiaries: (i) any merger,
consolidation or other business combination or (ii) and acquisition of any
capital stock or any material portion of such entity's assets (except for
acquisitions of assets in the ordinary course of business consistent with past
practice).
 
  Notwithstanding the nonsolicitation covenant contained in the Merger
Agreement, the Company may, in response to a "Favorable Third Party Proposal"
(as defined below) furnish information to, and negotiate or otherwise engage
in substantive discussions with, the party making such Favorable Third Party
Proposal if the Board or Directors of the Company determines in good faith by
a majority vote, that failing to take such action would constitute a breach of
the fiduciary duties of the Board. The term "Favorable Third Party Proposal"
is defined in the Merger Agreement as a written proposal from a credible third
party regarding the acquisition of substantially all the capital stock of the
Company, a merger, consolidation or other business combination with the
Company or a sale of substantially all the assets of the Company, which
proposal (i) is not subject to any financing or regulatory uncertainty greater
than the financing and regulatory uncertainties to which the transaction
contemplated by the Merger Agreement is subject, (ii) is, in the written
opinion of a nationally recognized investment bank, more favorable to the
Company's shareholders from a financial point of view than the transactions
contemplated hereby, and (iii) was not solicited by or on behalf of the
Company in violation of the nonsolicitation covenant contained in the Merger
Agreement. See "The Merger--No Solicitation."
 
TERMINATION
 
  The Merger Agreement may be terminated and the Merger abandoned, at any time
prior to the Effective Time, whether before or after approval by the Company's
shareholders, (i) by the mutual written consent of the Boards of Directors of
CII, the Merger Subsidiary and the Company; (ii) by any party if (A) the
Company's shareholders fail to approve the Merger at the Special Meeting or
(B) the Merger shall not have been consummated on or before June 30, 1998 (the
"Termination Date"); provided that if any condition to the Merger Agreement
shall fail to be satisfied by reason of the existence of an injunction or
order of any court or governmental or regulatory body, then at the request of
any party the deadline date referred to above shall be extended for a
reasonable period of time, not in excess of 30 days, to permit the parties to
have such injunction vacated or order reversed; (iii) by the Company, in the
event of a material breach by CII or Merger Subsidiary of any representation,
warranty or agreement of CII or Merger Subsidiary, in each case which has not
been cured or is not curable by the earlier of (A) the Termination Date or (B)
the 30th day after notice of such breach is given to CII or Merger Subsidiary
(as the case may be); (iv) by the Company, if the Company receives a firm
proposal with respect to an Acquisition Transaction which its Board of
Directors determines, in the exercise of its fiduciary duties as advised by
counsel, contains terms that are more favorable to the Company and its
constituents, taken as a whole, than the Merger; (v) by CII, in the event of a
material breach by the Company of any representation, warranty or agreement of
the Company which has not been cured or is not curable by the earlier of (A)
the Termination Date or (B) the 30th day after notice of such breach was given
to the Company; (vi) by either party if the conditions to be satisfied by the
other party pursuant the Merger Agreement shall not have been satisfied (or
waived) prior to the Termination Date; or (vii) by CII if a "triggering event"
occurs.
 
  A "Triggering Event" occurs under the Merger Agreement if (i) on or before
the Termination Date, a third party or group of related third parties become
the beneficial owners of 50% or more of the outstanding voting securities of
the Company by a tender offer, exchange offer, stock issuance or otherwise, or
(ii) the Merger is not consummated because (A)(1) the Company's Board of
Directors authorizes or recommends, or the Company enters into an agreement or
agreement in principle or closes, an Acquisition Transaction (other than the
Merger), or (2) the Company's Board of Directors fails to recommend to the
Company's shareholders that they vote to approve the Merger or adversely
modifies or withdraws its recommendation or takes any other action to abandon
 
                                       6
<PAGE>
 
or terminate the Merger Agreement as a result of a firm proposal with respect
to an Acquisition Transaction which the Board determines, in the exercise of
its fiduciary duties as advised by counsel, contains terms that are more
favorable to the Company and its constituents, taken as a whole, than the
Merger, or takes any action to abandon or terminate the Merger Agreement in
accordance with the foregoing, (B) the Special Meeting is not called by the
Termination Date or (C) the shareholders of the Company approve an Acquisition
Transaction (other than the Merger). See "The Merger--Termination of the
Merger Agreement."
 
TERMINATION FEE
 
  If the Merger Agreement is terminated and a Triggering Event occurs, then
the Company will pay to CII the sum of $2.0 million, and up to $500,000 of
transaction expenses. If the Merger Agreement is terminated by the Company
arising from a breach by CII of its obligations, then CII will reimburse the
Company for its out-of-pocket expenses up to $500,000. These amounts will be
payable upon termination of the Merger Agreement. See "The Merger--Fees and
Expenses."
 
EXCHANGE OF STOCK CERTIFICATES
 
  As soon as practicable after the Effective Time, instructions and a letter
of transmittal will be furnished to all the Company's shareholders of record
for use in exchanging their stock certificates for the Merger Consideration.
SHAREHOLDERS OF THE COMPANY SHOULD NOT SUBMIT THEIR STOCK CERTIFICATES FOR
EXCHANGE UNTIL SUCH INSTRUCTIONS AND LETTER OF TRANSMITTAL ARE RECEIVED. See
"The Merger--Exchange of Certificates Representing the Common Stock."

                              THE SPECIAL MEETING
 
GENERAL
 
  The Special Meeting of the shareholders of the Company will be held at the
offices D'Ancona & Pflaum, 30 North La Salle Street, 27th Floor, Chicago,
Illinois, at 10:00 a.m. local time, on June 18, 1998 to (i) consider and vote
upon the approval and adoption of the Merger Agreement and (ii) transact such
other business as may properly come before the Special Meeting or any
adjournment thereof.
 
  The Company's Board of Directors has unanimously approved the Merger
Agreement and the transactions contemplated thereby and has determined that
such transactions are in the best interests of the Company and its
shareholders. The Company's Board of Directors unanimously recommends that the
Company's shareholders vote for approval and adoption of the Merger Agreement.
For a description of certain conflicts of interests of the Company's
president, Werner Neuman, in approving the Merger Agreement, see "Special
Factors--Interests Of Certain Persons In The Merger."
 
RECORD DATE; QUORUM
 
  Only shareholders of record of the Company at the close of business on the
Record Date will be entitled to notice of, and to vote at, the Special
Meeting. On the Record Date, there were 3,921,543 shares of the Company's
common stock outstanding and entitled to vote at the Special Meeting. Each
holder of shares of the Company's common stock outstanding on the Record Date
is entitled to one vote for each such share so held, exercisable in person or
by properly executed and delivered proxy, at the Special Meeting. The presence
of the holders of at least a majority of the shares of the Company's common
stock outstanding on the Record Date, whether present in person or by properly
executed and delivered proxy, will constitute a quorum for purposes of the
Special Meeting.
 
VOTE REQUIRED
 
  The affirmative vote of the holders of record of at least two-thirds of the
outstanding shares of the Company's common stock entitled to vote at the
Special Meeting is necessary to approve and adopt the Merger Agreement.
Messrs. Neuman and Steinback who collectively held, as of the Record Date,
1,198,399 shares or 31.3% of the outstanding shares of the Company's common
stock have granted to Merger Subsidiary a proxy to vote such shares in favor
of approving and adopting the Merger Agreement. Where shareholders have
appropriately specified how their proxies are to be voted, they will be voted
accordingly. Abstentions and broker non-votes will have the same effect as
votes against approval of the Merger and will be counted toward determining
whether a quorum is present at the Special Meeting.
 
PROXIES
 
  Shareholders are requested to complete, date and sign the accompanying form
of proxy and return it promptly to the Company in the enclosed postage-paid
envelope.
 
  Any shareholder giving a proxy pursuant to this solicitation has the power
to revoke it at any time before it is voted at the Special Meeting by
notifying the Company, there being no formal procedure requirement. A later
dated proxy or notice of revocation given prior to the vote at the Special
Meeting to the Secretary of the Company will serve to revoke such proxy. Also,
a shareholder who attends the Special Meeting in person may, if he or she
wishes, vote by ballot at the Special Meeting, thereby canceling any proxy
previously given. Mere presence at the Special Meeting will not serve to
revoke any proxy previously given.
 
OTHER MATTERS TO BE CONSIDERED
 
  The Company's Board of Directors is not aware of any other matter which will
be brought before the Special Meeting. If, however, other matters are
presented, proxies will be voted in accordance with the discretion of the
holders of such proxies.
 
                                       9

SOLICITATION OF PROXIES
 
  D.F. King & Co., Inc. will assist in the solicitation of proxies for the
Company for a fee of approximately $5,000, plus reimbursement of reasonable
out-of-pocket expenses. Arrangements may also be made with brokerage houses
and other custodians, nominees and fiduciaries for the forwarding of
solicitation materials to the beneficial owners of shares of the Company's
common stock held of record by such persons, and the Company may reimburse
such persons for reasonable out-of-pocket expenses incurred by them in
connection therewith.
 
                                SPECIAL FACTORS
 
BACKGROUND OF THE MERGER
 
  On March 7 1996, the Company engaged The Chicago Dearborn Company
(predecessor firm to ABN AMRO Incorporated, "ABN AMRO") to review financial
and strategic alternatives for the purpose of assisting the Company explore
options for enhancing shareholder value. On April 30, 1996, the Company issued
a press release disclosing it had retained a financial advisor to explore
financial and strategic alternatives.
 
  From April 1996 to November 1996, ABN AMRO reviewed alternatives for the
Company which included engaging in discussions with strategic third parties to
explore various strategic relationships, including sale or merger
transactions. No proposal from a strategic third party resulted from these
discussions.
 
  On December 17, 1996, ABN AMRO representatives attended a meeting of the
Company's Board of Directors and discussed financial and strategic
alternatives with the Board. Share repurchase programs, minority equity
investments, ESOP structures, acquisitions, joint ventures and sale of the
Company alternatives were discussed at the meeting. The Board concluded from
this meeting that it would be in the shareholders' best interest to, at that
time, remain independent and continue implementing the Company's strategic
plan. Furthermore, the Board believed that the financial and business outlook
for 1997 appeared to be favorable and believed the Company would have the
opportunity to evaluate different alternatives as they became available.
 
  From January 1997 to December 1997, the Company referred unsolicited
inquiries received from several third parties to ABN AMRO. ABN AMRO held
informal discussions with these third parties, and no preliminary or formal
proposals resulted from these discussions. CII was not among the parties
described in this paragraph.
 
  CII was acquired by Code, Hennessy & Simmons LLC ("CHS"), a Chicago-based
private investment firm, in September 1997 and had been actively pursuing an
acquisition strategy to expand its product mix as well as its engineering and
distribution capabilities. In November 1997, CHS reviewed its acquisition
strategy for CII with ABN AMRO. As a result of these discussions, ABN AMRO
contacted Werner Neuman, President of the Company, to ascertain his interest
in learning more about CII and CHS. In December 1997, ABN AMRO organized a
meeting between CII representatives and Mr. Neuman. The meeting was an
introductory meeting to explore a possible strategic relationship between CII
and Corcom.
 
  Within a week after the initial meeting, CHS representatives communicated to
ABN AMRO that in conjunction with its portfolio company, CII, it would like to
pursue discussions to acquire Corcom. Around December 19, 1997, CHS
communicated to ABN AMRO that it placed a value of "around $11 per share" for
the Company's common stock. ABN AMRO, based on previous conversations with Mr.
Neuman, told CHS that it was unlikely the Board would consider a transaction
at that price level. On December 23, 1997, CHS delivered a non-binding
indication of interest (the "Indication") to ABN AMRO. The Indication was not
an offer and outlined many significant conditions. The Indication outlined
that based on publicly available information, CHS and CII indicated a
valuation range for Corcom of $12.25 to $13.25 per share (the "Indicated
Range"). Among other things, the Indication proposed that CHS and CII: (i)
begin business, legal and accounting due diligence, (ii) seek to obtain the
necessary financing to consummate a transaction and (iii) negotiate a mutually
satisfactory definitive Merger Agreement.
 
                                      10
<PAGE>
 
  On January 16, 1998, the engagement letter between the Company and its
financial advisor dated March 7, 1996 was amended. The portion of the
financial advisory fee paid on transaction value, as defined in the engagement
letter, in excess of $10 million was changed from 1.50% to 1.75%. The period
of time the financial advisory fee shall become due and payable, if a
transaction is consummated (i) after the engagement letter agreement is
terminated by the Company, (ii) after the engagement letter agreement is
terminated by ABN AMRO after a breach by the Company or (iii) after the
engagement letter agreement's term expires, was changed from nine months to
fifteen months.
 
  On January 6, 1998, CHS and CII agreed to a confidentiality and standstill
agreement with Corcom and began conducting due diligence which included
reviewing non-public information. In addition to performing legal, accounting
and business due diligence, CHS and CII representatives, along with a
representative from Bank of America, toured the Company's Juarez manufacturing
facility on January 29, 1998. Around February 20, 1998, CHS contacted ABN AMRO
to indicate it still had not completed its due diligence effort, but at that
point in time CHS anticipated it would be prepared to acquire Corcom at a
price per share around the midpoint of the Indicated Range. On February 25,
CHS and CII representatives met with Mr. Neuman to discuss various management
and operations issues. Both parties concluded from the meeting that a
strategic relationship between CII and Corcom could bring substantial
opportunities to their respective shareholders, employees, customers and
suppliers.
 
  Throughout the months of February and March, 1998 in connection with CII's
review of the Company and in the course of negotiations between the Company
and CII, the Company provided CII and its representatives with certain non-
public business and financial information, including, without limitation,
financial projections, historical revenue and expense detail, detailed
customer information, accounts receivable reports and inventory reports. The
financial projections given to CII are summarized under the caption "Special
Factors--Opinion of Financial Advisor." Such financial projections do not give
effect to the Merger or the financing thereof. The data included in such
financial projections was the only material, nonpublic information provided to
CII or its representatives by the Company or its representatives.
 
  On February 27, Mr. Neuman contacted Board members and called for a Board
meeting on March 9 in Chicago to discuss the terms of a potential transaction.
 
  On March 6, Corcom's legal and financial advisors met with CHS
representatives, CHS legal advisors and Bank of America representatives to
discuss various issues involving the Merger Agreement and related documents.
Negotiations between the parties continued until March 10. Poor weather
conditions in Chicago forced the Company Board meeting to be postponed from
March 9 to March 10.
 
  On March 10, 1998, ABN AMRO communicated to CHS that CHS would need to be
higher than the midpoint of the Indicated Range for the Board to consider a
transaction. CHS told ABN AMRO it was prepared to pay no more than $13.00 per
share. Subsequently, CHS delivered to ABN AMRO an executed Merger Agreement
and related documents indicating that it was prepared to acquire all of the
outstanding shares of the Company at $13.00 per share in cash.
 
  At the March 10 Board meeting, ABN AMRO and the Company's legal advisors
reviewed key provisions of the Merger Agreement and ABN AMRO presented an
extensive valuation analysis of the Company. ABN AMRO presented its written
opinion that the merger price of $13.00 per share in cash (the "Merger Price")
to be offered to the Company's shareholders in the Merger would be fair to the
Company's shareholders from a financial point of view. The Board of Directors
unanimously determined that, in light of the valuation discussions concerning
the Company, ABN AMRO's fairness opinion and the other factors described
below, the Merger Price would be fair to and in the best interest of the
Company's shareholders and that it would recommend to the Company's
shareholders that they vote in favor of the Merger. Following the Board
meeting, the Company executed the Merger Agreement.
 
  On the morning of March 11, the Company issued a press release announcing
the transaction and the principal terms and conditions thereof.

REASONS FOR THE MERGER AND RECOMMENDATION OF THE COMPANY'S BOARD OF DIRECTORS
 
  The Company's Board of Directors has determined that the terms of the Merger
Agreement, which were established through arm's-length bargaining with CHS and
CII, and the transactions contemplated thereby, are fair to, and in the best
interests of, the Company and its shareholders. Accordingly, the Company's
Board of Directors has unanimously approved the Merger Agreement and
unanimously recommends that the shareholders vote for approval and adoption of
the Merger Agreement and the approval of the terms of the Merger. For a
description of certain conflicts of interests of the Company's President,
Werner E. Neuman, in approving the Merger Agreement, see "Special Factors--
Interests Of Certain Persons In The Merger."
 
  In reaching its determination, the Company's Board of Directors consulted
with the Company's management, as well as its legal and financial advisors,
and considered and weighed the following material matters:
 
    (i) An assessment of the Company's strategic alternatives, which include
  remaining a publicly owned independent company. In this regard, the Board
  of Directors concluded, following extensive analysis and discussion with
  its legal and financial advisors and among the directors, that the terms of
  the Merger Agreement provide the best means for holders of the Company's
  common stock to maximize the value of their holdings at this time;
 
    (ii) The familiarity of the Board with the Company's business, financial
  condition, results of operations, properties and prospects as an
  independent entity, and the nature of the industry in which it operates,
  based in part upon presentations by the Company's management and financial
  advisors;
 
    (iii) The results of the process undertaken by the Company to identify
  and solicit proposals from third parties to enter into a strategic
  transaction with the Company, the small number of unsolicited inquiries
  from potential bidders and based on these factors, the low likelihood that
  any third party would propose to acquire the Company at a price higher than
  $13.00 per share;
 
    (iv) The terms and conditions of the Merger Agreement, including the
  right of the Company to negotiate and provide information to third parties
  under certain circumstances. If the Merger Agreement is terminated after an
  Acquisition Transaction, the Company would be obligated to pay CII $2.0
  million and up to $500,000 of expenses and fees. The Company's Board of
  Directors did not view these obligations as unreasonably precluding any
  third party from proposing an alternative transaction and concluded that
  entering into the Merger Agreement given the available strategic
  alternatives was in the best interests of the Company;
 
    (v) The presentation of the Company's financial advisor, ABN AMRO, and
  its opinion dated March 10, 1998, to the effect that, as of such date and
  based upon and subject to the matters reviewed with the Board of Directors,
  the $13.00 per share Merger Price to be received by the shareholders
  pursuant to the Merger was fair to such holders from a financial point of
  view. A copy of the written opinion of ABN AMRO is attached as Appendix B
  to this Proxy Statement. SHAREHOLDERS ARE URGED TO READ THE OPINION OF ABN
  AMRO CAREFULLY IN ITS ENTIRETY; for a summary of ABN AMRO's opinion,
  including the assumptions made, matters considered and limits of review,
  see "--Opinion of Financial Advisor"; and
 
    (vi) The recent trading price of the Company's common stock and that the
  Merger Price represents a premium of 33.3% over the closing price as
  reported on Nasdaq on March 10, the last trading day prior to the public
  announcement of the execution of the Merger Agreement.
 
  The Board of Directors also recognized and considered the fact that
consummation of the Merger is subject to certain conditions, including CII's
obtaining financing substantially similar to the financing outlined in a
commitment letter addressed to CII from Bank of America National Trust and
Savings Association. The Board of Directors discussed and acknowledged that
due to such conditions, there is a risk that the Merger will not be
consummated. If the Merger is not consummated, the public announcement of the
Merger and non-consummation of the Merger could have an adverse effect on the
Company's operational plans, employee morale, financing prospects and the
market price of the Company's common stock. In addition, in evaluating the
 
                                      12
<PAGE>
 
Merger, the Board of Directors discussed the potential disadvantage in the
shareholders of the Company no longer being able to participate in the
potential future growth of the Company.
 
  In view of the wide variety of factors considered in connection with its
evaluation of the Merger, the Company's Board of Directors did not find it
practicable to, and did not, quantify or otherwise attempt to assign relative
weights to the specific factors considered in reaching its determination, each
of which was viewed as supportive of its conclusion that the terms of the
Merger Agreement are fair to, and in the best interests of, the Company and
its shareholders.
 
  THE COMPANY'S BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE COMPANY'S
SHAREHOLDERS VOTE TO APPROVE AND ADOPT THE MERGER AGREEMENT. FOR A DESCRIPTION
OF CERTAIN CONFLICTS OF INTERESTS OF THE COMPANY'S PRESIDENT, WERNER E.
NEUMAN, IN APPROVING THE MERGER AGREEMENT SEE "SPECIAL FACTORS--INTERESTS OF
CERTAIN PERSONS IN THE MERGER."
 
VOTING AGREEMENT
 
  Messrs. Neuman and Steinback who collectively held, as of the Record Date,
1,198,399 shares or 31.3% of the outstanding shares of the Company's common
stock, have entered into a voting agreement, dated March 10, 1998, with Merger
Subsidiary (the "Voting Agreement") pursuant to which each of them has (i)
agreed to vote their respective shares of common stock in favor of the Merger,
and (ii) granted to Merger Subsidiary a proxy to vote such shares in favor of
approving and adopting the Merger Agreement. The obligations of Messrs. Neuman
and Steinback are effective, however, only upon the occurrence of certain
conditions. Specifically, the Voting Agreement provides that if Messrs. Neuman
and Steinback provide Merger Subsidiary with at least three business days
notice prior to any meeting of the shareholders of the Company (or any action
by written consent of the shareholders of the Company), in which the
shareholders of the Company will vote on the adoption of the Merger Agreement,
or the approval or adoption of any action or agreement that would adversely
affect the Merger, then the voting obligation and proxy contained in the
Voting Agreement is effective if, and only if, Merger Subsidiary has either
(i) entered into a definitive credit agreement for the purpose of financing
the Merger or (ii) waived its financing condition to closing of the Merger
Agreement. The Voting Agreement is automatically effective if Messrs. Neuman
and Steinback do not provide Merger Subsidiary with at least three business
days notice prior to any meeting or action of the shareholders of the Company,
as described above.
 
  No consideration was paid to CII nor Messrs. Neuman and Steinback in
connection with entering into the voting agreement. Other than the voting
agreement and the Merger Agreement, there are no affiliations between the
Company, its management and respective subsidiaries and CII, its management
and respective subsidiaries.
 
OPINION OF FINANCIAL ADVISOR
 
  The Company retained ABN AMRO to act as its financial advisor and to render
an opinion to the Board of Directors of the Company as to the fairness, from a
financial point of view, of the consideration to be received by the holders of
the Company's common stock in the Merger.
 
  On March 10, 1998, in connection with the evaluation of the proposal from
CII by the Board of Directors of the Company, ABN AMRO rendered an opinion
that, as of such date, and subject to certain assumptions, factors and
limitations set forth in such written opinion as described below, the
consideration to be received by the Company's shareholders is fair to such
shareholders from a financial point of view.
 
  THE FULL TEXT OF THE WRITTEN OPINION OF ABN AMRO DATED MARCH 10, 1998 IS
ATTACHED AS APPENDIX B TO THIS PROXY STATEMENT AND SHOULD BE READ IN ITS
ENTIRETY FOR INFORMATION WITH RESPECT TO PROCEDURES FOLLOWED, ASSUMPTIONS MADE
AND MATTERS CONSIDERED BY ABN AMRO IN RENDERING SUCH OPINION. ABN AMRO'S
OPINION WAS PREPARED FOR THE COMPANY'S BOARD OF DIRECTORS AND ADDRESSES ONLY
THE FAIRNESS OF
 
                                      13
<PAGE>
 
THE CONSIDERATION TO THE HOLDERS OF THE COMPANY'S COMMON STOCK FROM A
FINANCIAL POINT OF VIEW. THE ABN AMRO OPINION DOES NOT CONSTITUTE A
RECOMMENDATION TO ANY SHAREHOLDER OF THE COMPANY AS TO HOW SUCH SHAREHOLDER
SHOULD VOTE WITH RESPECT TO THE PROPOSED MERGER. THE SUMMARY OF THE OPINION OF
ABN AMRO SET FORTH IN THIS PROXY STATEMENT CONTAINS ALL MATERIAL ELEMENTS OF
SUCH OPINION, BUT IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT
OF SUCH OPINION.
 
  In connection with its opinion, ABN AMRO has, among other things: (a)
reviewed the Merger Agreement and certain related documents; (b) held
discussions with certain senior officers and other representatives and
advisors of the Company concerning the business, operations and prospects of
the Company; (c) examined certain publicly available business and financial
information relating to the Company as well as certain financial data and
other data for the Company which were provided to or otherwise discussed with
ABN AMRO by the management of the Company; (d) reviewed the financial terms of
the Merger as set forth in the Merger Agreement in relation to, among other
things: (i) current and historical market prices and trading volumes of the
Company's common stock; (ii) the Company's financial and other operating data;
and (iii) the capitalization and financial condition of the Company. ABN AMRO
also considered, to the extent publicly available, the financial terms of
certain other similar transactions recently effected which ABN AMRO considered
relevant in evaluating the Merger and analyzed certain financial, stock market
and other publicly available information relating to the businesses of other
companies whose operations ABN AMRO considered relevant in evaluating those of
the Company. ABN AMRO did not receive any instructions from the Company with
respect to the analyses performed in arriving at its opinion, nor did the
Company impose any limitations on the scope of the investigation or the
analyses performed by ABN AMRO.
 
  In rendering its opinion, ABN AMRO has, with the Company's consent, assumed
and relied upon the accuracy and completeness of the financial and other
information reviewed by it and it did not make or obtain or assume any
responsibility for independent verification of such information. In addition,
with the Company's consent, ABN AMRO did not make an independent evaluation or
appraisal of the assets and liabilities of Corcom or any of its respective
subsidiaries. With respect to the financial data, ABN AMRO has assumed, with
the Company's consent, that it has been reasonably prepared on bases
reflecting the best currently available estimates and judgments of the
management of the Company as to the future financial performance of the
Company. ABN AMRO has assumed, with the Company's consent, that the Merger
will be consummated in accordance with the terms of the Merger Agreement. ABN
AMRO's opinion is necessarily based on economic, monetary, market and other
conditions as in effect on, and the information made available to ABN AMRO as
of, the date of its opinion.
 
  There have been no recent public solicitations of indications of interest in
a possible acquisition of the Company. However, in connection with its
engagement, ABN AMRO approached a limited number of third parties to solicit
indications of interest in a possible acquisition of the Company and held
preliminary discussions with certain of these parties.
 
  The following is a summary of the material financial analyses ABN AMRO
utilized in connection with providing its written opinion to the Board of
Directors of the Company on March 10, 1998. The summary of the analyses
contains all material elements of such analyses, but does not purport to be a
complete description of the analyses underlying ABN AMRO's opinion.
 
    (a) Stock Trading History. ABN AMRO reviewed the performance of the
  trading price and volume of the Company's common stock for the period from
  March 8, 1996 through March 10, 1998. This examination indicated that
  during this period, the trading price of the Company's common stock ranged
  from $6.00 per share to $12.75 per share, and the weekly volume ranged from
  1,300 shares to 357,400 shares.
 
    (b) Implied Multiple and Premium Analysis. ABN AMRO calculated certain
  valuation multiples implied by the terms of the Merger Agreement based on a
  per share value for each share of the Company's common stock of $13.00. ABN
  AMRO calculated that the total equity value as a multiple of the Company's
  latest twelve months' ("LTM") net income, projected calendar 1998 net
  income, and projected calendar 1999 net income was 17.1x, 14.9x and 13.0x,
  respectively, based on a per share value of $13.00. ABN
 
                                      14
<PAGE>
 
  AMRO also calculated that the total enterprise value (defined to be total
  equity value plus total debt less cash and cash equivalents, also referred
  to as adjusted market capitalization) as a multiple of the Company's LTM
  earnings before interest and taxes ("EBIT"), LTM earnings before interest,
  taxes, depreciation and amortization ("EBITDA") and LTM sales was 8.9x,
  7.1x, and 1.1x, respectively, based on a per share value of $13.00.
 
    ABN AMRO calculated the percentage premium implied by the terms of the
  Merger Agreement relative to the market price of the Company's common stock
  one day, one week and four weeks prior to the announcement of the Merger.
  ABN AMRO calculated that the percentage premium to the market price of the
  Company's common stock one day, one week and four weeks prior to the
  announcement of the Merger was 33.3%, 30.0% and 35.1%, respectively.
 
    (c) Discounted Cash Flow Analysis. ABN AMRO performed discounted cash
  flow analyses of the Company based on estimates of projected financial
  performance prepared by the Company's management for the fiscal years 1998
  to 2002. ABN AMRO calculated a range of present values of the sum of: (i)
  the Company's estimated free cash flows for the fiscal years ending 1998
  through 2002 using discount rates ranging from 15.0% to 18.0%, and (ii) the
  estimated terminal value in fiscal year 2002 based on a multiple of the
  Company's EBITDA in fiscal 2002 ranging from 4.5x to 5.5x and discounted at
  rates ranging from 15.0% to 18.0%. Using the foregoing discounted cash
  flows and terminal values, ABN AMRO calculated the equity value per share
  of the Company's common stock to range from $10.32 to $12.39.
 
    The table below summarizes key income statement, balance sheet and cash
  flow data from the Company's projections.

    The Company does not as a matter of course publicly disclose projections
  as to future revenues or earnings. The projections provided to ABN AMRO
  were not prepared with a view to public disclosure and are included in the
  Proxy Statement only because such information was made available to ABN
  AMRO in connection with its opinion regarding fairness of the Merger Price
  to the Company's shareholders from a financial point of view. Accordingly,
  it is expected that there will be differences between actual and projected
  results, and actual results may be materially different than those
  described. The projections were not prepared with a view to compliance with
  the published guidelines of the Commission regarding projections, nor were
  they prepared in accordance with the guidelines established by the American
  Institute of Certified Public Accountants for preparation and presentation
  of financial projections, and the projections were not and are not intended
  to be representations or warranties by the Company as to its future
  performance. These forward-looking statements reflect numerous assumptions
  made by the Company's management. In addition, factors including but not
  limited to industry performance, general business, economic, regulatory and
  market and financial conditions, all of which are difficult to predict, may
  cause
 
                                      15
<PAGE>
 
  the projections provided to ABN AMRO or the underlying assumptions to be
  inaccurate. Accordingly, there can be no assurance that the projections
  provided to ABN AMRO will be realized, and actual results may be materially
  greater or less than those contained therein.
 
    The inclusion of the projections provided to ABN AMRO herein should not
  be regarded as an indication that ABN AMRO or the Company considered or
  consider the projections to be a reliable prediction of future events, and
  the projections should not be relied upon as such.
 
    (d) Comparable Public Company Analysis. ABN AMRO compared certain
  financial and operating information for the Company to the corresponding
  financial and operating information of the following group of electronic
  component manufacturing companies which were selected based on their
  product mix, distribution channels and profitability characteristics (the
  "Comparable Companies"): Aerovox Inc., AVX Corporation, Burr-Brown
  Corporation, KEMET Corporation, Methode Electronics, Inc., RF Monolithics,
  Inc., Spectrum Control, Inc., Thermo Voltek Corp., and Vishay
  Intertechnology, Inc. ABN AMRO analyzed, among other things, the market
  price per share of common stock of each Comparable Company and Corcom as a
  multiple of LTM EPS, estimated calendar 1998 EPS, and estimated calendar
  1999 EPS (estimates for comparables provided by Zacks Investment Research,
  estimates for Spectrum Control were not available), and the adjusted market
  capitalization as a multiple of LTM EBIT, LTM EBITDA, and LTM sales. For
  the Comparable Companies (excluding outliers), an analysis of market price
  per share as a multiple of LTM EPS yielded a range of 12.7x to 17.0x with a
  mean of 14.8x; an analysis of market price per share as a multiple of
  estimated 1998 EPS yielded a range of 12.0x to 13.9x with a mean of 13.0x;
  an analysis of market price per share as a multiple of estimated 1999 EPS
  yielded a range of 10.4x to 11.4x with a mean of 11.0x; an analysis of
  adjusted market capitalization as a multiple of LTM EBIT yielded a range of
  8.7x to 13.0x with a mean of 10.2x; an analysis of adjusted market
  capitalization as a multiple of LTM EBITDA yielded a range of 6.4x to 8.2x
  with a mean of 6.9x; an analysis of adjusted market capitalization as a
  multiple of LTM sales yielded a range of 1.05x to 1.49x with a mean of
  1.29x. Based on this analysis and applying the mean multiples to the
  Company's historical and estimated financial results, ABN AMRO estimated
  the implied value per share of the Company's common stock to range from
  $11.02 to $14.37. ABN AMRO identified the LTM EBIT multiple as less
  relevant because of Corcom's low depreciation relative to the comparable
  companies and the LTM sales multiple as less relevant because it does not
  account for profitability characteristics. The market price per share as a
  multiple of estimated calendar 1998 and the market price per share as a
  multiple of estimated calendar 1999 were not available for Spectrum
  Control. All other cited multiples were available for the Comparable
  Companies. Based on this analysis and applying the mean multiples,
  excluding LTM EBIT and LTM sales multiples, to the Company's historical and
  estimated financial results, ABN AMRO estimated the implied value per share
  of the Company's common stock to range from $11.02 to $12.88.
 
    (e) Comparable Transactions Analysis. ABN AMRO analyzed certain
  information relating to selected transactions where public data was
  available in the electronic components manufacturing industry (the
  "Comparable Transactions"). The Comparable Transactions were selected based
  the target's product mix, distribution channels and profitability
  characteristics and include the following: Zytec Corporation/Computer
  Products, Inc.; Tower Electronics, Inc./Advanced Energy Industries, Inc.;
  C&S Hybrid/Remec, Inc.; Opal Inc./Applied Materials, Inc.; Augat,
  Inc./Thomas & Betts Corp.; Hazeltine Corp. (ESCO Electronics)/GEC-Marconi
  Electronics Systems Corporation; Fenwal Electronics, Inc. (Publicker
  Industries Inc.)/Elmwood Sensors; Amerace Corp. (Eagle Industrial Products
  Corp.)/Thomas & Betts Corp.; Pulse Engineering, Inc./Technitrol, Inc.; M/A-
  Com Inc./AMP Inc.; Vitramon Inc. (Thomas & Betts Corp.)/Vishay
  Intertechnology Inc.; Astrio Corp./Altron Inc.; TeleSciences Transmission
  Systems, Inc./California Microwave, Inc.; Sundstrand Data
  Control/AlliedSignal Inc.; Base2 Systems/Brooktree Corp.; and Microwave
  Radio Corp./California Microwave, Inc. Such analysis indicated that for the
  Comparable Transactions (excluding outliers), total equity value as a
  multiple of LTM net income ranged from 7.4x to 25.8x with a mean of 14.7x,
  total enterprise value as a multiple of LTM EBIT ranged from 4.3x to 14.7x
  with a mean of 9.9x, total enterprise value as a multiple of LTM EBITDA
  ranged from 4.1x to 10.2x with a mean of 7.0x and total enterprise value as
  a multiple of LTM sales ranged from 0.4x to 1.6x with a mean of 1.1x. LTM
  EBITDA multiples were not available for the following transactions:
  Hazeltine
 
                                      16
<PAGE>
 
  Corp. (ESCO Electronics)/GEC-Marconi Electronics Systems Corporation;
  Fenwal Electronics, Inc. (Publicker Industries Inc.)/Elmwood Sensors;
  Vitramon Inc. (Thomas & Betts Corp.)/Vishay Intertechnology Inc.; and
  Sundstrand Data Control/AlliedSignal Inc. All other cited multiples and
  data for the transactions and companies referenced above were available and
  used in each analysis performed. Based on this analysis and applying the
  mean multiples to the Company's historical financial results, ABN AMRO
  estimated the implied value per share of the Company's common stock to
  range from $11.17 to $14.04. For the same reasons discussed in paragraph
  (d), ABN AMRO identified the LTM EBIT and LTM sales multiples as less
  relevant. Based on this analysis and applying the mean multiples, excluding
  LTM EBIT and LTM sales multiples, to the Company's historical financial
  results, ABN AMRO estimated the implied value per share of the Company's
  common stock to range from $11.17 to $12.69.
 
    (f) Premium Analysis. ABN AMRO analyzed the percentage premiums offered
  in forty-two cash transactions of $30 million to $100 million in size
  announced since January 1, 1996. ABN AMRO calculated the premium offered
  relative to the market price one day, one week, and four weeks prior to the
  announcement date of each transaction. The analysis indicated that the
  median percentage premium one day, one week, and four weeks prior to
  announcement was 18.4%, 20.5% and 29.7%, respectively. All cited premiums
  were available for all cash transactions of $30.0 million to $100.0 million
  in size announced since January 1, 1996. Based on this analysis and
  applying the median premiums to the market price of the Company's common
  stock one day, one week and four weeks prior to the announcement of the
  Merger, ABN AMRO estimated the implied value per share of the Company's
  common stock to range from $11.52 to $11.84.
 
  The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to practical analysis or summary description.
Selecting portions of the analyses or of the summary set forth above, without
considering the analyses as a whole, could create an incomplete view of the
processes underlying ABN AMRO's opinion. In arriving at its fairness
determination, ABN AMRO considered the results of all such analyses. No
company or transaction used in the above analyses as a comparison is identical
to the Company or the Merger. The analyses were prepared for purposes of ABN
AMRO's opinion for the benefit and use of the Board of Directors in its
consideration of the Merger and may not be used for any other purpose, except
that the opinion letter may be discussed and included in any proxy statement
of the Company relating to the Merger. The analyses do not purport to be
appraisals or necessarily reflect the prices at which businesses or securities
actually may be sold. Analyses based upon forecasts of future results are not
necessarily indicative of actual future results, which may be significantly
more or less favorable than suggested by such analyses. Because such analyses
are inherently subject to uncertainty, being based upon numerous factors or
events beyond the control of the parties or their respective advisors, none of
the Company, CII, ABN AMRO or any other person assumes responsibility if
future results are materially different from those forecast.
 
  Corcom selected ABN AMRO as its financial advisor because ABN AMRO is a
nationally recognized investment banking firm that has substantial experience
in transactions similar to the Merger. ABN AMRO, as part of its investment
banking business, is continually engaged in the valuation of businesses in
connection with mergers and acquisitions, as well as initial and secondary
offerings of securities and valuations for other purposes. In the ordinary
course of ABN AMRO's business, ABN AMRO and its affiliates may actively trade
securities of Corcom for their own account and for the accounts of customers
and, accordingly, may at any time hold a long or short position in such
securities.
 
  The consideration to be received by the shareholders of the Company pursuant
to the Merger was determined through negotiations between the Company and CII
and was approved by the Company's Board of Directors. ABN AMRO provided advice
to the Company during the course of such negotiations; however, the decision
to enter into the Merger Agreement and accept the offer of CII was solely that
of the Company's Board of Directors.
 
  Pursuant to a letter agreement dated March 7, 1996 and amended on January
16, 1998 (the "Engagement Letter"), Corcom engaged ABN AMRO to act as its
financial advisor in connection with the Merger. Pursuant to the terms of the
Engagement Letter, Corcom has paid ABN AMRO $75,000 for retainer fees and owes
ABN AMRO an additional $100,000 for rendering the fairness opinion. Pursuant
to the terms of the Engagement Letter, Corcom will pay ABN AMRO, on the
Closing Date, cash compensation equal to $150,000 and one and three-quarters
percent (1.75%) of the transaction value in excess of $10 million, less
amounts paid previously
 
                                      17
<PAGE>
 
under the Engagement Letter. Further, Corcom has agreed to reimburse ABN AMRO
for its reasonable out-of-pocket expenses, including attorney's fees, and to
indemnify ABN AMRO against certain liabilities, including certain liabilities
under the federal securities laws. If the Merger is consummated, ABN AMRO will
receive, in connection with its engagement, approximately $804,000 from Corcom
which is net of the retainer fees, and excludes reimbursement of out-of-pocket
expenses.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
  In considering the recommendations of the Company's Board of Directors, the
Company shareholders should be aware that certain members of management and
the Company's Board of Directors have interests in the Merger that are in
addition to the interests of the Company shareholders generally and which
create conflicts of interest.
 
  Consulting and Noncompetition Agreement. A condition to CII's obligations
under the Merger Agreement is that Mr. Neuman execute a two-year consulting
agreement, effective January 1, 1999 (the "Consulting Agreement"). Although
the Consulting Agreement will not be executed until the Effective Time, the
parties have agreed to a form of agreement that was delivered by CII to Mr.
Neuman in connection with the execution of the Merger Agreement. Under the
form of Consulting Agreement agreed to by Mr. Neuman and CII, Mr. Neuman will
provide consulting services to the Company from time to time for a period of
two years. In consideration of these consulting services and a noncompetition
covenant during the term of the agreement, Mr. Neuman will receive $211,000
per annum, use of a Company owned automobile and health benefits that are no
less favorable to Mr. Neuman than the policies in effect prior to the
Effective Time. The form of Consulting Agreement also contains customary
nonsolicitation covenants and confidentiality provisions.
 
 
  Change of Control Payment. On November 9, 1988, Mr. Neuman entered into an
employment agreement with the Company, which was amended on September 1, 1990
(the "Neuman Employment Agreement"). Pursuant to the terms of the Neuman
Employment Agreement, Mr. Neuman is employed as President at a minimum
compensation of $150,000 per annum for a term to continue in effect until
terminated by either party on specified written prior notice. Upon a
termination of Mr. Neuman's employment for any reason, other than death,
subsequent to a "change in control" (as defined in the Neuman Employment
Agreement), Mr. Neuman is entitled to all amounts then due to him under the
agreement and to a lump sum termination payment equal to 250% of the average
of his annual minimum and bonus compensation for services during the three
years preceding such termination of employment. Upon written notice by Mr.
Neuman to the Company that a change in control is intended or contemplated or
shall occur in the future, the Company will be obligated to place in escrow
the amounts necessary to fund the amounts due to Mr. Neuman as described in
the preceding sentence.
 
  The Merger will constitute a "change of control" of the sort contemplated by
the Neuman Employment Agreement. Mr. Neuman has indicated to the Company that
he plans to give notice of intent to terminate his employment with the Company
to be effective on December 31, 1998. Therefore, if the Merger is consummated,
Mr. Neuman will be entitled to a "change of control" payment from the Company.
Under the terms of the Consulting Agreement agreed upon by Mr. Neuman and CII,
Mr. Neuman will accept an amount equal to $850,000 as his "change of control"
payment for purposes of the Neuman Employment Agreement, which will be payable
on December 31, 1998. The amounts to be paid to Mr. Neuman as a change of
control payment under the Neuman Employment Agreement and as consulting fees
under the Consulting Agreement are in addition to the amounts Mr. Neuman would
be entitled to receive pursuant to the Merger due to his ownership of shares
of common stock of the Company generally.
 
  Severance Payments. Pursuant to the terms of the Merger Agreement, the
Company is allowed to enter into severance agreements with certain employees
prior to the consummation of the Merger. Under the terms of these severance
agreements, employees shall be entitled to a payment equal to their base
salary and bonus in fiscal 1997 in the event their employment with the Company
is terminated by the Company without "cause" (as defined) at any time prior to
the first anniversary of the Effective Time. The Company plans to enter into
such severance agreements with each of Michael Raleigh (Vice President--
Engineering and Quality Assurance),
 
                                      18
<PAGE>
 
Fernando Pena (Vice President--Manufacturing), Oswald Hoffman (Manager--Corcom
GmbH), Gary Baltimore (Vice President--Sales), Joseph Ritter (Vice President--
Pacific Region Sales) and Sherrill Bishop (Vice President--Human Resources).
 
  In addition, Thomas J. Buns, Vice President and Treasurer of the Company,
has an agreement with the Company for his employment. The agreement may be
terminated by either party on six months prior written notice. Upon a
termination of employment for any reason by the Company, other than "cause"
(as defined), or death, subsequent to a "change in control" (as defined), Mr.
Buns shall be entitled to all amounts then due him and to a lump sum
termination payment equal to 100% of the average of his annual minimum and
bonus compensation for services during the year preceding such termination.
Following the Effective Time, if Mr. Buns' employment is terminated by the
Company without cause during the term of his employment agreement, he will be
entitled to such a severance payment. The total of Mr. Buns' minimum and bonus
compensation for fiscal 1997 was approximately $204,000.
 
  Treatment of Stock Options. Certain officers, directors and employees of the
Company hold options to purchase the Company's common stock granted under the
Option Plans. Under the terms of the Merger Agreement, all options granted
under the Option Plans (whether or not vested or exercisable) will be canceled
at or about the Effective Time, and the holders of the options will be
entitled to receive an amount in cash equal to the product of (i) the
difference between $13.00 and the exercise price of such option and (ii) the
number of shares of the Company's common stock subject to such option. As of
May 20, 1998, there were options outstanding to purchase an aggregate of
142,000 shares of the Company's common stock at a weighted average exercise
price of $3.33 per share.
 
  The following table sets forth information as to the options outstanding on
May 20, 1998, for which cash payment will be received upon consummation of the
Merger (assuming there is no exercise of such options prior to the Effective
Time), and the proceeds to be received upon termination of such options by the
directors and executive officers of the Company:

  Director and Officer Indemnification and Insurance. CII has agreed in the
Merger Agreement that after the Effective Time, the Company will indemnify its
current and former officers and directors for any losses, claims, damages,
costs and other liabilities or claims made against such persons because they
were a director or officer of the Company to the fullest extent permitted by
Articles of Incorporation and Bylaws of the Company. In addition, the Merger
Agreement provides that for six years after the Effective Time, the Company
will maintain its current directors' and officers' liability insurance for the
benefit of its directors and officers (or substitute policies of at least the
same coverage and containing terms not materially adverse to the indemnified
parties).

EFFECTIVE TIME AND CONSEQUENCES OF THE MERGER
 
  If approved by the requisite vote of the shareholders of the Company and if
all other conditions to the consummation of the Merger are satisfied or
waived, the Merger will become effective, unless the Merger Agreement is
terminated as provided therein, upon the making of certain filings with the
Secretary of State of the State of Illinois pursuant to the IBCA. At the
Effective Time, Merger Subsidiary will be merged with and into the Company,
which will be the Surviving Corporation in the Merger, and the separate
corporate existence and identity of Merger Subsidiary will cease. The
corporate existence and identity of the Company will continue unaffected by
the Merger, although it will become a wholly owned subsidiary of CII.
 
  It is currently contemplated that the Effective Time of the Merger will
occur as promptly as practicable after the approval of the Merger by the
Company's shareholders at the Special Meeting, subject to the conditions
described under "The Merger--Conditions to Merger."
 
  As a result of the Merger, the entire equity interest in the Company will be
owned by CII. The shareholders of the Company will no longer have any interest
in, and will not be shareholders of, the Company, and therefore will not
participate in its future earnings and growth. Instead, each such holder of
the Company's common stock will have the right to receive $13.00 in cash,
without interest, for each share held (other than the Unconverted Shares).
Following the Merger, CII will have the opportunity to benefit from any
earnings and growth of the Company, and will bear the risk of any decrease in
the Company's value. Following the Merger, the Company's common stock will no
longer be traded on Nasdaq, price quotations will no longer be available and
the registration of the Company's common stock under the Exchange Act will be
terminated.
 
  At the Effective Time, the present board of directors of the Company will be
replaced with the board of directors of Merger Subsidiary. The present
executive officers of the Company will initially be the officers of the
Surviving Corporation after the Effective Time.
 
  CII expects that, following consummation of the Merger, the business and
operations of the Company will be continued substantially as they are
currently being conducted. The board of directors and management of the
Company will, however, continue to evaluate the Company's business,
operations, corporate structure and organization and will make such changes as
they deem appropriate.
 
FEDERAL INCOME TAX CONSEQUENCES
 
  A shareholder who exchanges the shares of the Company's common stock for
cash pursuant to the Merger or exercises appraisal rights will recognize gain
or loss equal to the difference between the cash received in the Merger or
pursuant to the exercise of appraisal rights and such shareholder's adjusted
tax basis in the shares exchanged. Gain or loss recognized will be treated as
a long-term capital gain or loss if the shares are held as capital assets and
if the shares of the Company's common stock exchanged have a holding period of
more than one year at the Effective Time. Even if the gain or loss is treated
as a long-term capital gain or loss, the tax rate will vary depending on the
holding period.

DISSENTERS' RIGHTS
 
  Under Illinois law, each shareholder of Corcom has dissenters' appraisal
rights provided such shareholder does not vote in favor of the Merger
Agreement and complies with certain statutory procedures within the time
frames specified by the IBCA. The value determined in such appraisal could be
more than, the same as, or less than the value of the Merger Consideration,
depending upon the results of the statutory appraisal process. Sections 11.65
and 11.70 of the IBCA, which contain the provisions relating to dissenters'
appraisal rights, are set forth on Appendix C to this Proxy Statement. IT IS A
CONDITION TO CII'S OBLIGATION TO CONSUMMATE THE MERGER THAT DISSENTERS'
APPRAISAL RIGHTS NOT BE PERFECTED WITH RESPECT TO MORE THAN 5% OF THE
OUTSTANDING SHARES OF CORCOM COMMON STOCK. See "The Merger--Appraisal Rights
of Dissenting Shareholders."
 
                                  THE MERGER
 
  The terms and conditions of the Merger are set forth in the Merger
Agreement, the text of which is attached to this Proxy Statement as Appendix
A. The summary of the Merger Agreement contained in this Proxy Statement does
not purport to be complete and is qualified in its entirety by reference to
the complete text of such document.
 
  At the time the Merger becomes effective, Merger Subsidiary will be merged
with and into the Company in accordance with Illinois law. As a result of the
Merger, the separate corporate existence of Merger Subsidiary (which was
formed solely for the purposes of the Merger and has not engaged in any
operations or business) will cease, and the Company will continue its
existence as a separate subsidiary of CII.
 
  Upon the consummation of the Merger, each share of the Company's common
stock (except for Unconverted Shares) will be converted into the right to
receive $13.00 in cash.
 
EXCHANGE OF CERTIFICATES REPRESENTING THE COMMON STOCK
 
  Instructions with regard to the surrender of the Company's stock
certificates, together with a letter of transmittal to be used for this
purpose, will be mailed to the Company's shareholders of record as promptly as
practicable after the Effective Time. In order to receive the Merger
Consideration, the shareholders of the Company will be required to surrender
their stock certificates after the Effective Time, together with a duly
completed and executed letter of transmittal, to American Stock Transfer and
Trust Company (the "Paying Agent"). Promptly after the Effective Time, the
cash amount of the Merger Consideration will be deposited in trust with the
Paying Agent. Upon receipt of such stock certificates and letter of
transmittal, the Paying Agent will deliver the Merger Consideration to the
registered holder or his transferee of the shares of the Company's common
stock. No interest will be paid or accrued on the amounts payable upon the
surrender of stock certificates.
 
  SHAREHOLDERS SHOULD NOT SUBMIT THEIR STOCK CERTIFICATES FOR EXCHANGE UNTIL
THE INSTRUCTIONS AND LETTER OF TRANSMITTAL ARE RECEIVED.
 
  If the Merger Consideration is to be delivered to a person other than the
person in whose name the certificate for the shares of the Company's common
stock surrendered in exchange therefor is registered, it will be a condition
to the payment of such Merger Consideration that the stock certificate so
surrendered be properly endorsed and otherwise in proper form for transfer,
and that the person requesting such payment (i) pay in advance any transfer or
other taxes required by reason of the payment of the Merger Consideration to a
person other than the registered holder of the stock certificate surrendered
or (ii) establish to the satisfaction of the Paying Agent that such tax has
been paid or is not applicable.
 
  After the Effective Time, there will be no further transfers on the stock
transfer books of the Company of the shares of the Company's common stock that
were outstanding immediately prior to the Effective Time. If a
 
                                      21
<PAGE>
 
certificate representing such shares is presented for transfer, subject to
compliance with the requisite transmittal procedures, it will be canceled and
exchanged for the Merger Consideration.
 
  Each certificate representing shares of the Company's common stock
immediately prior to the Effective Time (other than the Unconverted Shares)
will, at the Effective Time, be deemed for all purposes to represent only the
right to receive the Merger Consideration into which the shares of the
Company's common stock represented by such certificate were converted in the
Merger.
 
  Any Merger Consideration delivered or made available to the Paying Agent and
not exchanged for stock certificates within 180 days after the Effective Time
will be returned by the Paying Agent to the Company, which will thereafter act
as Paying Agent. Neither CII, the Company or the Paying Agent will be liable
to a holder of shares of the Company's common stock for any of the Merger
Consideration delivered to a public official pursuant to applicable abandoned
property, escheat or similar laws.
 
TREATMENT OF OUTSTANDING OPTIONS
 
  The Merger Agreement provides that all options outstanding under the Option
Plans, whether or not exercisable, shall be canceled at the Effective Time.
Holders of the options will be entitled to receive (subject to applicable
withholding taxes) an amount in cash equal to the product of (i) the
difference between $13.00 and the exercise price of such option and (ii) the
number of shares of the Company's common stock subject to such option. As of
May 7, 1998, there were options outstanding to purchase an aggregate of
142,000 shares of the Company's common stock at a weighted average exercise
price of $3.33 per share.
 
CONDITIONS TO MERGER
 
  Each party's obligation to effect the Merger is subject to the satisfaction
of a number of conditions, which may be waived by a specified party or

amount equal to the aggregate Merger Consideration shall have been deposited
with the Paying Agent and (iii) the delivery of an opinion of Kirkland & Ellis
with respect to certain legal matters.

AMENDMENT OF THE MERGER AGREEMENT; WAIVER OF CONDITIONS
 
  The respective Boards of Directors of CII, Merger Subsidiary and the Company
may, by written agreement, at any time before or after the approval of the
Merger Agreement by the Company's shareholders, amend the Merger Agreement,
provided that after such shareholder approval no amendment or modification may
be made that would amend the Merger Price or materially adversely affect the
rights of the Company's shareholders without the further approval of such
shareholders. Each party may extend the time for the performance of any of the
obligations of any other party to the Merger Agreement, waive any inaccuracies
in the representations or warranties of any other party contained in the
Merger Agreement, waive compliance or performance by any other party with any
covenants, agreements or obligations contained in the Merger Agreement or
waive the satisfaction of any condition that is precedent to its performance
under the Merger Agreement.
 
CONDUCT OF BUSINESS PENDING THE MERGER
 
  The Company has agreed that during the period from the date of the Merger
Agreement to the Effective Time, except as otherwise provided in the Merger
Agreement or consented to by CII, each of the Company and its subsidiaries
will conduct its business in the usual, regular, and ordinary course of
business substantially the same manner as conducted prior to the date of the
Merger Agreement and will use all reasonable efforts to preserve intact its
business organization, keep available the services of its current officers and
employees and preserve relationships with customers, suppliers and others
having material business dealings with it to the end that its goodwill and
ongoing business shall not be impaired in any material respect at the
Effective Time. The Company has further agreed that it will not or permit its
subsidiaries to take certain enumerated actions which include the following:

other securities; (v) without the prior written consent of CII, (a) except for
increases in salary and wages granted to officers and hourly employees of the
Company or its subsidiaries in the ordinary course of business consistent with
past practice, grant any increases in the compensation of any of its
directors, officers or employees, (b) pay or agree to pay any pension,
retirement allowance or other employee benefit not required or contemplated to
be paid prior to the Effective Time by any of the existing benefit plans or
employee arrangements as in effect on the date of the Merger Agreement to any
such director, officer or employee, whether past or present, (c) enter into
any new, or materially amend any existing, employment, severance, or
termination agreement with any such director, officer, or key employee or, (d)
except as may be required by law, become obligated under any new employee

of the Merger Agreement, or amend any such plan or arrangement in existence on
the date of the Merger Agreement; provided, that the Company is allowed to
enter into severance agreements with each of Michael Raleigh, Fernando Pena,
Oswald Hoffman, Gary Baltimore, Joseph Ritter and Sherrill Bishop in the form
previously agreed to between the Company and CII; (vi) acquire, sell, lease or
dispose of any assets or securities which are material to the Company and the

business consistent with past practice; (vii) except as previously disclosed
to CII by the Company (a) incur, assume or pre-pay any long-term debt or incur
or assume any short-term debt, except in the ordinary course of business in

either case that is material to the Company and its subsidiaries; or (xi)
agree in writing or otherwise to take any of the foregoing actions or any
action which would cause any representation or warranty in the Merger
Agreement to be or become untrue or incorrect in any material respect.
 
NO SOLICITATION
 
  The Merger Agreement provides that neither the Company nor any of its
representatives will directly or indirectly (i) solicit, initiate, facilitate
or encourage any inquiries or the making of any proposal with respect to any
Acquisition Transaction, or (ii) negotiate or otherwise engage in substantive
discussions with any person (other than Merger Subsidiary or CII) with respect
to any Acquisition Transaction or enter into any agreement, arrangement or
understanding requiring it to abandon, terminate or fail to consummate the
Merger or any other transactions contemplated by the Merger Agreement.
Notwithstanding the nonsolicitation covenant contained in the Merger
Agreement, the Company may, in response to a Favorable Third Party Proposal,
furnish information to, and negotiate or otherwise engage in substantive
discussions with, the party making such Favorable Third Party Proposal if the
Board or Directors of the Company determines in good faith by a majority vote,
that failing to take such action would constitute a breach of the fiduciary
duties of the Board.
 
TERMINATION OF THE MERGER AGREEMENT
 
  The Merger Agreement may be terminated and the Merger abandoned, at any time
prior to the Effective Time, whether before or after the approval by the
Company's shareholders, (i) by the mutual written consent of the Boards of
Directors of CII, the Merger Subsidiary and the Company; (ii) by any party if
(A) the Company's shareholders fail to approve the Merger at the Special
Meeting or (B) the Merger shall not have been consummated on or before the
Termination Date; provided that if any condition to the Merger Agreement shall
fail to be satisfied by reason of the existence of an injunction or order of
any court or governmental or regulatory body, then at the request of any party
the deadline date referred to above shall be extended for a reasonable period
of time, not in excess of 30 days, to permit the parties to have such
injunction vacated or order reversed; (iii) by the Company, in the event of a
material breach by CII or Merger Subsidiary of any representation, warranty or
agreement of CII or Merger Subsidiary, in each case which has not been cured
or is not curable by the earlier of (A) the Termination Date or (B) the 30th
day after notice of such breach is given to CII or Merger Subsidiary (as the
case may be); (iv) by the Company, if the Company receives a firm proposal
with respect to an Acquisition Transaction which its Board of Directors
determines, in the exercise of its fiduciary duties as advised by counsel,
contains terms that are more favorable to the Company and its constituents,
taken as a whole, than the Merger; (v) by CII, in the event of a material
breach by the Company of any representation, warranty or agreement of the
Company which has not been cured or is not curable by the earlier of (A) the
Termination Date or (B) the 30th day after notice of such breach was given to
the Company; or (vi) by either party if the conditions to be satisfied by the
other party pursuant the Merger Agreement shall not have been satisfied (or
waived) prior to the Termination Date.
 
  In addition, the Merger Agreement may be terminated by CII if a "triggering
event" occurs whereby (i) on or before the Termination Date, a third party or
group of related third parties become the beneficial owners of 50% or more of
the outstanding voting securities of the Company by a tender offer, exchange
offer, stock issuance or otherwise, or (ii) the Merger is not consummated
because (A)(1) the Company's Board of Directors authorizes or recommends, or
the Company enters into an agreement or agreement in principle or closes, an
Acquisition Transaction (other than the Merger), or (2) the Company's Board of
Directors fails to recommend to the Company's shareholders that they vote to
approve the Merger or adversely modifies or withdraws its recommendation or
takes any other action to abandon or terminate the Merger Agreement as a
result of a firm
 
                                      24
<PAGE>
 
proposal with respect to an Acquisition Transaction which the Board
determines, in the exercise of its fiduciary duties as advised by counsel,
contains terms that are more favorable to the Company and its constituents,
taken as a whole, than the Merger, or takes any action to abandon or terminate
the Merger Agreement in accordance with the foregoing, (B) the Special Meeting
is not called by the Termination Date or (C) the shareholders of the Company
approve an Acquisition Transaction (other than the Merger).
 
  If CII or the Company terminates the Merger Agreement as provided above,
there will be no liability on the part of any party or its officers, directors
or shareholders, except as described in "Fees and Expenses" below.
 
FEES AND EXPENSES
 
  The Merger Agreement provides that all costs and expenses in connection with
the Merger Agreement and the transactions contemplated thereby shall be paid
by the party incurring such expense, except as otherwise provided in the
Merger Agreement. If the Merger Agreement is terminated and a Triggering Event
has occurred, then the Company will pay to CII the sum of $2.0 million, and up
to $500,000 of expenses incurred in connection with the transactions
contemplated by the Merger Agreement. The Company has agreed to pay this
amount within three days of the occurrence of such Triggering Event.
 
  If Merger Agreement is terminated by the Company arising from a breach by
CII of its obligations, then CII will reimburse the Company for its out-of-
pocket expenses. These amounts will be payable upon termination of the Merger
Agreement.
 
REPRESENTATIONS AND WARRANTIES
 
  The Merger Agreement contains various representations and warranties of the
parties, including representations and warranties by the Company with respect
to its corporate existence and power, capital structure, corporate
authorization, noncontravention, consents and approvals, SEC filings,
information supplied, compliance with applicable laws, litigation, taxes,
pension and benefit plans and ERISA, absence of certain changes or events,
absence of undisclosed material liabilities, opinion of financial advisor,
vote required, labor matters, intangible property, proprietary rights,
accounts receivable, inventory, warranties, environmental matters, real
property, board recommendation, material contracts, related party
transactions, indebtedness, liens, and other matters.
 
  CII and Merger Subsidiary have also made certain representations and
warranties with respect to corporate existence and power, corporate
authorization, consent and approvals, noncontravention, information supplied,
board recommendation, financing, and other matters.
 
CERTAIN REGULATORY MATTERS
 
  Consummation of the Merger is conditioned upon receipt by CII and the
Company of such regulatory and other approvals as are required under
applicable law. Other than matters described below, CII and the Company know
of no such regulatory or other approvals required by law.
 
  Under the HSR Act, certain acquisition transactions, including the proposed
Merger, may not be consummated unless certain information has been furnished
to the Federal Trade Commission (the "FTC") and the Antitrust Division of the
Justice Department (the "Antitrust Division") and certain waiting period
requirements have expired or been terminated. In accordance with the HSR Act,
CII and the Company each filed Notification and Report Forms and certain
supplementary materials with the Antitrust Division and the FTC for review in
connection with the proposed Merger. The FTC granted early termination of the
waiting period under the HSR Act on April 10, 1998.
 
 
                                      25

INDEMNIFICATION
 
  The Merger Agreement provides that the Company will, and from and after the
Effective Time indemnify, defend and hold harmless each person who was at the
date of the Merger Agreement, or had been at any time prior to the date of the
Merger Agreement or who becomes prior to the Effective Time, an officer or
director of the Company (the "Indemnified Parties") against all losses,
claims, damages, costs, expenses (including attorneys' fees and expenses),
liabilities or judgments or amounts paid in settlement with the approval of
the indemnifying party (which approval shall not be unreasonably withheld) of
or in connection with any threatened or actual claim, action, suit, proceeding
or investigation based in whole or in part on or arising in whole or in part
on, or arising in whole or in part out of the fact that such person is or was
a director or officer of the Company or any of its subsidiaries whether
pertaining to any matter existing or occurring at or prior to the Effective
Time and whether asserted or claimed prior to, or at or after, the Effective
Time ("Indemnified Liabilities"), including all Indemnified Liabilities based
in whole or in part on, or arising in whole or in part out of, or pertaining
to the Merger Agreement or the transactions contemplated thereby, in each
case, to the full extent a corporation is permitted under the Articles of
Incorporation and Bylaws of the Company to indemnify its own directors or
officers, as the case may be. All rights to indemnification existing in favor
of the Indemnified Parties with respect to matters occurring through the
Effective Time, shall survive the Merger and shall continue in full force and
effect for a period of not less six years from the Effective Time.
 
DIRECTORS' AND OFFICERS' INSURANCE
 
  For a period of six years after the Effective Time, the Company shall cause
to be maintained in effect the current policies of directors' and officers'
liability insurance maintained by the Company and its subsidiaries (provided
that CII may substitute therefor policies of at least the same coverage and
containing terms and conditions which are not materially less advantageous to
the parties to be indemnified) with respect to matters arising before the
Effective Time.
 
FINANCING
 
  It is estimated that approximately $44.0 million (net of cash and cash
equivalents of the Company) will be required to consummate the Merger. The
principal source for financing the Merger will be a credit facility with a
senior lender. CII has received a commitment letter from Bank of America
National Trust and Savings Association to provide up to $60 million in senior
secured credit facilities, which will be split between a $25 million revolving
credit and a $35 million term loan. This senior secured credit facility will
be used by CII: (i) to acquire the common stock of the Company in the Merger;
(ii) to refinance up to $7.5 million of CII's existing indebtedness; (iii) to
provide for working capital needs; (iv) for general corporate purposes; and
(v) to pay related fees and expenses. This financing is subject to certain
conditions, including the execution of a definitive credit agreement
satisfactory to Bank of America and there being no material adverse change in
the financial condition, business, operations, properties or prospects of the
Company or CII. See "The Merger--Financing."
 
APPRAISAL RIGHTS OF DISSENTING SHAREHOLDERS
 
  Any shareholder of the Company who does not vote in favor of the Merger
Agreement and who gives written notice prior to the vote by the shareholders
of Corcom to approve the Merger Agreement may demand dissenters' appraisal
rights pursuant to Sections 11.65 and 11.70 of the IBCA. Copies of these
sections are attached as Appendix C hereto. Dissenting shareholders may elect
to receive payment in cash in an amount equal to the estimated "fair value" of
their shares, which will be the value of the shares immediately before the
consummation of the Merger excluding any appreciation or depreciation in
anticipation of the Merger, unless such exclusion would be inequitable. The
following is a summary of the procedural steps which must be taken to ensure
that a dissenting shareholder's appraisal rights are recognized.
 
  IT IS A CONDITION TO CII AND MERGER SUBSIDIARY'S OBLIGATION TO CONSUMMATE
THE MERGER, THAT DISSENTERS' APPRAISAL RIGHTS NOT BE PERFECTED WITH RESPECT
 
                                      26
<PAGE>
 
TO MORE THAN 5% OF THE OUTSTANDING SHARES OF CORCOM COMMON STOCK. SEE "--
CONDITIONS TO MERGER."
 
  A SHAREHOLDER DESIRING TO PERFECT HIS OR HER RIGHT TO PAYMENT FOR HIS OR HER
SHARES MUST MAIL OR DELIVER TO THE COMPANY (ATTENTION: THOMAS BUNS, TREASURER,
CORCOM, INC., 844 EAST ROCKLAND ROAD, LIBERTYVILLE, ILLINOIS 60048), A WRITTEN
DEMAND FOR PAYMENT OF HIS OR HER SHARES BEFORE THE VOTE ON THE MERGER
AGREEMENT IS TAKEN, AND SUCH SHAREHOLDER MUST NOT VOTE IN FAVOR OF THE MERGER
AGREEMENT. THE DELIVERY OF A PROXY WITH INSTRUCTIONS TO VOTE THE SHARES
REPRESENTED THEREBY AGAINST APPROVAL OF THE MERGER AGREEMENT WILL NOT, BY
ITSELF, SATISFY THE REQUIREMENT OF A WRITTEN DEMAND.
 
  Only a holder of record is entitled to request dissenters' appraisal rights
and payment for the shares registered in his or her name. A record owner of
shares may assert dissenters' appraisal rights as to fewer than all of the
shares recorded in such person's name only if such person dissents with
respect to all shares beneficially owned by any one person and notifies the
Company in writing of the name and address of each person on whose behalf the
record owner asserts dissenters' appraisal rights. The rights of a partial
dissenter are determined as if the shares as to which dissent is made and the
other shares held by such holder of record are recorded in the names of
different shareholders of the Company. A beneficial owner of shares who is not
the record owner may assert dissenters' appraisal rights as to shares held on
such person's behalf only if the beneficial owner submits to the Company the
record owner's written consent to the dissent before or at the same time the
beneficial owner asserts dissenters' appraisal rights.
 
  A demand must reasonably inform the Company of the identity of the holder of
record of the shares of common stock covered by the demand and that such
holder of record demands payment for such shares. The demand should be
executed by or for the shareholder of record, fully and correctly, as such
shareholder's name appears on his or her Corcom stock certificate(s).
 
  A Corcom shareholder who makes written demand for payment retains all other
rights of as a shareholder until those rights are canceled or modified at the
Effective Time by the consummation of the Merger. Within ten days after the
Effective Time, the CII shall send each dissenting shareholder who has
delivered a written demand for payment, a statement setting forth the opinion
of CII as to the estimated fair value of the shares of common stock, Corcom's
1997 financial statements, Corcom's latest available interim financial
statements, and a commitment to pay for the shares of common stock held by the
dissenting shareholder the estimated fair value thereof upon transmittal to
CII of the Corcom stock certificate or certificates.
 
  Upon consummation of the Merger, and given demand for payment by a
dissenting shareholder, CII shall, upon receipt of the applicable stock
certificates, pay the amount CII estimates to be the fair value of the shares,
plus accrued interest, if any. An explanation of how the interest was
calculated will be provided by CII to the dissenting shareholder at the time
that CII pays the amount it estimates to be the fair value of the shares.
 
  If the dissenting Corcom shareholder does not agree with the opinion of CII
as to the estimated fair value of the shares, or the amount of interest due,
he or she shall, within thirty days from the delivery of CII's statement of
value, notify CII in writing of such shareholder's determination of the
estimated fair value and interest due relating to the shares, and demand
payment of the difference.
 
  If within sixty days after delivery of such written notification by a
dissenting shareholder, CII and the dissenting shareholder are unable to agree
as to the value of the shares, CII shall either pay the difference in value
demanded by the shareholder, with interest, or file a petition in the Circuit
Court of Cook County, Illinois requesting a determination of the fair value of
the shares and the interest due. All shareholders who have perfected their
dissenters' appraisal rights and who have not settled with CII will be made
parties to this proceeding. The cost of the proceedings may be assessed
against one or more parties to the proceedings as the
 
                                      27
<PAGE>
 
court may consider equitable. Failure of CII to commence an action shall not
limit or affect the right of the dissenting shareholder to otherwise commence
an action as permitted by law.
 
  The foregoing is only a summary of the provisions of the IBCA and is
qualified in its entirety by reference to the text of Sections 11.65 and 11.70
of the IBCA which are set forth in Appendix C hereto and incorporated by
reference herein. ANY SHAREHOLDERS OF THE COMPANY WHO DESIRES TO EXERCISE HIS
OR HER DISSENTERS' APPRAISAL RIGHTS SHOULD CAREFULLY REVIEW APPENDIX C AND IS
ADVISED TO CONSULT A LEGAL ADVISOR BEFORE ELECTING OR ATTEMPTING TO EXERCISE
SUCH RIGHTS.

Agreement (the "Closing") shall take place at the offices of Kirkland & Ellis

                                  ARTICLE II
 
                     DISSENTING SHARES; PAYMENT FOR SHARES
 
  Section 2.01 Dissenting Shares. Notwithstanding anything in this Agreement
to the contrary, Common Shares outstanding immediately prior to the Effective
Time and held by a holder who has demanded and perfected his or her appraisal
rights in accordance with Section 5/11.65 of the Illinois Act and who has not
effectively withdrawn or lost his right to such appraisal, if such Section
5/11.65 provides for dissenters' rights for such Common Shares in the Merger
(a "Dissenting Share"), shall not be converted into the right to receive the
Merger Price as provided in Section 1.07, unless and until such holder fails
to perfect or withdraws or otherwise loses his right to appraisal and payment
under the Illinois Act, but the holder thereof shall only be entitled to such
rights as are granted by the Illinois Act and shall not be entitled to vote or
to exercise any other rights of a shareholder of the Company except as
provided in the Illinois Act. Each holder of Dissenting Shares who becomes
entitled to payment therefor pursuant to the Illinois Act shall receive such
payment from the Surviving Corporation in accordance with the Illinois Act.
If, after the Effective Time, any such holder fails to perfect or withdraws or
loses his right to dissent, such Dissenting Shares shall thereupon be treated
as if they had been converted as of the Effective Time into the right to
receive the Merger Price, if any, to which such holder is entitled, without
interest or dividends thereon. The Company shall give the Parent prompt notice
of any demands received by the Company for appraisal of Common Shares and,
prior to the Effective Time, the Parent shall have the right to participate in
all negotiations and proceedings with respect to such demands. Prior to the
Effective Time, the Company shall not, except with the prior written consent
of the Parent, make any payment with respect to, or settle or offer to settle,
any such demands.
 
  Section 2.02 Payment for Common Shares.
 
    (a) From and after the Effective Time, a bank or trust company as shall
  be mutually acceptable to the Parent and the Company shall act as paying
  agent (the "Paying Agent") in effecting the payment of the Merger Price in
  respect of certificates (the "Certificates") that, prior to the Effective
  Time, represented Common Shares entitled to payment of the Merger Price
  pursuant to Section 1.07. At the Effective Time, the Parent or the Merger
  Sub shall deposit, or cause to be deposited, in trust with the Paying Agent
  the Aggregate Common Share Merger Price to which holders of Common Shares
  shall be entitled at the Effective Time pursuant to Section 1.07.
 
    (b) Promptly after the Effective Time, the Paying Agent shall mail to
  each record holder of Certificates that immediately prior to the Effective
  Time represented Common Shares (other than Certificates representing
  Dissenting Shares and Certificates representing Common Shares held by the
  Parent or the Merger Sub, any wholly-owned subsidiary of the Parent or the
  Merger Sub, in the treasury of the Company or by any wholly-owned
  subsidiary of the Company) a form of letter of transmittal which shall
  specify that delivery shall be effected, and risk of loss and title to the
  Certificates shall pass, only upon proper delivery
 
                                      A-3
<PAGE>
 
  of the Certificates to the Paying Agent and instructions for use in
  surrendering such Certificates and receiving the Merger Price in respect
  thereof. Upon the surrender of each such Certificate, the Paying Agent
  shall pay the holder of such Certificate the Merger Price multiplied by the
  number of Common Shares formerly represented by such Certificate, in
  consideration therefor, and such Certificate shall forthwith be canceled.
  Until so surrendered, each such Certificate (other than Certificates
  representing Dissenting Shares and Certificates representing Common Shares
  held by the Parent or the Merger Sub, any wholly owned subsidiary of the
  Parent or the Merger Sub, in the treasury of the Company or by any wholly-
  owned subsidiary of the Company) shall represent solely the right to
  receive the Aggregate Common Share Merger Price relating thereto. No
  interest or dividends shall be paid or accrued on the Merger Price. If the
  Merger Price (or any portion thereof) is to be delivered to any person
  other than the person in whose name the Certificate formerly representing
  Common Shares surrendered therefor is registered, it shall be a condition
  to such right to receive such Merger Price that the Certificate so
  surrendered shall be properly endorsed or otherwise be in proper form for
  transfer and that the person surrendering such Common Shares shall pay to
  the Paying Agent any transfer or other taxes required by reason of the
  payment of the Merger Price to a person other than the registered holder of
  the Certificate surrendered, or shall establish to the satisfaction of the
  Paying Agent that such tax has been paid or is not applicable.
 
    (c) Promptly following the date which is 180 days after the Effective
  Time, the Paying Agent shall deliver to the Surviving Corporation all cash,
  Certificates and other documents in its possession relating to the
  transactions described in this Agreement, and the Paying Agent's duties
  shall terminate. Thereafter, each holder of a Certificate formerly
  representing a Common Share may surrender such Certificate to the Surviving
  Corporation and (subject to applicable abandoned property, escheat and
  similar laws) receive in consideration therefor the Aggregate Common Share
  Merger Price relating thereto, without any interest or dividends thereon.
 
    (d) After the Effective Time, there shall be no transfers on the stock
  transfer books of the Surviving Corporation of any Common Shares which were
  outstanding immediately prior to the Effective Time. If, after the
  Effective Time, Certificates formerly representing Common Shares are
  presented to the Surviving Corporation or the Paying Agent, they shall be
  surrendered and canceled in return for the payment of the Aggregate Common
  Share Merger Price relating thereto, as provided in this Article II,
  subject to applicable law in the case of Dissenting Shares.
 
    (e) If any Certificate shall have been lost, stolen or destroyed, upon
  the making of an affidavit of that fact by the person claiming such
  Certificate to be lost, stolen or destroyed and, if required by the
  Surviving Corporation, the posting by such person of a bond, in such
  reasonable amount as the Surviving Corporation may direct, as indemnity
  against any claim that may be made against it with respect to such
  Certificate, the Paying Agent will issue in exchange for such lost, stolen
  or destroyed Certificate the Merger Price as provided in Section 1.07.
 
                                  ARTICLE III

    (a) The Company Disclosure Statement sets forth a true and complete list
  of all Plans (as defined below) maintained or sponsored by the Company or
  any Subsidiary, contributed to by the Company or any Subsidiary, to which
  the Company or any Subsidiary is obligated to contribute or with respect to
  which the Company or any Subsidiary has any liability or potential
  liability, including all Plans contributed to, maintained or sponsored by
  any member of the controlled group of companies, within the meaning of
  Sections 414(b) and 414(c) of the Internal Revenue Code of 1986, as amended
  (the "Code"), of which the Company and/or any Subsidiary is or, during the
  last three years, ever was a member (the "Company Controlled Group") (to
  the extent that the Company or any Subsidiary has any liability or
  potential liability with respect to such Plans). For purposes of this
  Agreement, the term "Plans" shall mean: (i) employee benefit plans as
  defined in Section 3(3) of the Employee Retirement Income Security Act of
  1974, as amended ("ERISA"), whether or not funded, (ii) employment
  agreements, and (iii) personnel policies or fringe benefit plans, policies,
  programs and arrangements, whether or not subject to ERISA, whether or not
  funded, and whether or not covering employees residing in the United
  States, including without limitation, stock bonus, stock option, stock
  appreciation right, stock purchase, "phantom stock," deferred compensation,
  pension, profit sharing, savings, severance, bonus, vacation, incentive,
  travel, and health, disability and welfare plans. Neither the Company nor
  any Subsidiary has any commitment, whether formal or informal, to create
  any additional employee benefit plans, or to modify any existing Plan
  except as may be required to conform to changes in applicable law.
 
    (b) Neither the Company nor any Subsidiary has within the last five years
  participated in, contributed to or been obligated to contribute to any
  "multiemployer plan", as such term is defined in Section 3(37) of ERISA
  ("Multiemployer Plan"), nor does the Company or any Subsidiary have any

  and Section 302 of ERISA. There has been no complete or partial termination
  of any Plan which could result in any material liability to the Company or
  any Subsidiary.
 
                                      A-8
<PAGE>
 
    (d) Neither the Company nor any Subsidiary maintains or has any
  obligation to contribute to (or has any other liability or potential
  liability with respect to) any Plan which provides health, life insurance,
  accident or other "welfare-type" benefits to current or future retirees,
  current or future former employees, current or future former independent
  contractors, or the spouses, dependents or beneficiaries thereof, other
  than in accordance with Section 4980B of the Code, Sections 601 et seq. of
  ERISA, and/or other applicable continuation coverage law.
 
    (e) None of the Plans obligates the Company or the Subsidiaries to pay
  separation, severance, termination or similar-type benefits solely as a
  result of any transaction contemplated by this Agreement or solely as a
  result of a "change in control", as such term is defined in Section 280G of
  the Code.
 
    (f) With respect to each Plan, all required payments, premiums,
  contributions, reimbursements or accruals for all periods ending prior to
  or as of the Effective Time shall have been made or properly accrued. No
  Plan has any unfunded liabilities.
 
    (g) Each Plan and all related trusts, insurance contracts and funds have
  been maintained, funded, and administered in material compliance in all
  respects with all applicable laws and regulations, including but not
  limited to ERISA and the Code. Neither the Company nor any Subsidiary has
  incurred, or expects to incur, any liability to the Internal Revenue
  Service ("IRS"), the Department of Labor, any other governmental (whether
  of the United States or otherwise) agency, or any person with respect to
  any Plan currently or previously maintained by members of the Company
  Controlled Group that has not been satisfied in full, and no condition
  exists that presents a risk to the Company and/or the Subsidiaries or any
  other member of the Company Controlled Group of incurring such a liability
  (other than liability for routine benefit claims). None of the Company, any
  Subsidiary, any trustee or administrator of any Plan, or other person has
  engaged in any transaction with respect to the Plans which could subject
  the Company, any Subsidiary, or any trustee or administrator of the Plans,
  or any party dealing with any Plan, to any tax or penalty (civil or
  otherwise) imposed by ERISA, the Code or other applicable law. No actions,
  investigations, suits or claims with respect to the Plans (other than
  routine claims for benefits) or any fiduciary or other person dealing with
  such Plans are pending or threatened and the Company has no knowledge of
  any facts which could give rise to or be expected to give rise to any such
  actions, investigations, suits or claims.
 
    (h) No prohibited transaction within the meaning of Section 4975 of the
  Code or Section 406 of ERISA has occurred with respect to any Plan, other
  than a transaction which is exempt under Section 408 of ERISA or for which
  no excise tax is assessed under Section 4975 of ERISA.
 
    (i) All Plans which are intended to be qualified under Section 401(a) of
  the Code have received a favorable determination letter from the IRS.
 
    (j) No underfunded defined benefit plan has been, during the five years
  preceding the Effective Time, transferred out of the Company Controlled
  Group.
 
    (k) With respect to each Plan, and upon the request of the Parent, the
  Company has provided the Parent with true, complete and correct copies, to
  the extent applicable, of all documents pursuant to which the Plans are
  maintained, funded and administered.
 
  Section 3.14 Material Contracts and Other Agreements. The Company Disclosure
Statement sets forth a complete and accurate list of the following contracts
and commitments to which the Company or any Subsidiary is a party or by which
any of their respective properties are bound: (a) collective bargaining
agreements and contracts with any labor union; (b) employment or consulting

payments; (c) leases, whether as lessor or lessee, involving personal property
with annual rental payments in excess of $50,000; (d) loan agreements,

business pursuant to existing credit agreements in respect of inventory
purchases) in each case involving indebtedness (or available credit) for
borrowed money or money lent to others; (e) guaranty or suretyship,
performance bond, indemnification or contribution agreements; (f) written

                                      A-9

less notice without premium or penalty; (g) joint venture, partnership, or
other agreements evidencing an ownership interest or a participation in or

control of the Company, (j) written contracts with distributors of the
Company's or any of the Subsidiaries' products, and (k) any other agreements
material to the Company and its Subsidiaries taken as a whole. The Company has
furnished or made available accurate and complete copies of the foregoing
contracts and agreements to the Parent. The termination of any oral agreement
or understanding to which the Company or a Subsidiary is a party of the type
described in Sections 3.14(f) and 3.14(j) above would not, to the Company's
knowledge, have a Material Adverse Effect on the Company. Each such oral
agreement or understanding is terminable by the Company or a Subsidiary, as
the case may be, without premium or penalty. As to each contract and
commitment referred to above (i) there exists no breach or default, and no
event has occurred which with notice or passage of time would constitute such
a breach or default or permit termination, notification or acceleration, on
the part of the Company or any Subsidiary or, to the best knowledge of the
Company, on the part of any third party and (ii) as of the Effective Time, no
third party consent, approval or authorization shall be required for the
consummation of the Transactions. This Section 3.14 does not relate to real
property, such items being the subject of Section 3.15.

purchase or acquire any interest in real property; and (c) all options granted
by the Company or the Subsidiaries or contractual obligations on the part of
the Company or the Subsidiaries to sell or dispose of any interest in real
property. Except as set forth in the Company Disclosure Statement, as to such
leases, subleases and other agreements referred to above, (i) there exists no
breach or default, and no event has occurred which with notice or passage of
time would constitute such a breach or default or permit termination,
notification or acceleration, on the part of the Company or any Subsidiary, or
on the part of any other party thereto, and (ii) as of the Effective Time, no
material third party consent, approval or authorization shall be required for
the consummation of the Merger. To the Company's knowledge, there are no Liens
on any of the leasehold interests set forth on the Company Disclosure
Statement hereof except for (i) Liens reflected in the balance sheet included
in the Company's Form 10-K for the period ended December 31, 1996, (ii) Liens
of record consisting of zoning or planning restrictions, easements, permits
and other restrictions or limitations on the use of real property which do not
materially detract from the value of, or materially impair the use of, such

respective businesses, (iii) Liens for current Taxes (as defined in Section

such as materialman's, mechanic's, carrier's, workers' and repairmen's Liens

accordance with customary and commercially reasonable practice. (collectively,
"Permitted Liens").
 
  Section 3.16 Real Property. The Company Disclosure Statement lists all real
property owned by the Company and the Subsidiaries. Each of the Company and
the Subsidiaries has good and marketable title in fee simple to its respective
real properties set forth on the Company Disclosure Statement, in each case,

Liens.
 
  Section 3.17 Compliance with Laws. The Company and the Subsidiaries have
substantially complied and, to the Company's knowledge, are in substantial
compliance with applicable federal, state or local statutes, laws and
regulations including, without limitation, any applicable building, zoning,
health, sanitation, safety, labor relations or other law, ordinance or
regulation. Neither the Company nor any Subsidiary has (a) failed to obtain
any license, permit, franchise or other governmental authorization which is
necessary to the operations of the
 
                                     A-10
<PAGE>
 
business of the Company and the Subsidiaries, taken as a whole, or (b)

has any rights and all contracts, agreements and licenses relating to any of
the foregoing. All right, title and interest in and to each of the foregoing

not limited to know-how and formulas), computer software and other material
intellectual property rights necessary for the conduct of their respective
businesses as now being conducted (collectively, the "Proprietary Rights"). To
the Company's knowledge, neither the Company nor any Subsidiary has infringed
or is infringing on any Proprietary Rights belonging to any other person, firm
or corporation. Neither the Company nor any of the Subsidiaries has granted
any licenses with respect to any of their respective Proprietary Rights.
Neither the Company nor any of the Subsidiaries has received any notice, nor
does the Company or any of the Subsidiaries have any knowledge of any
infringement or misappropriation by or misuse or conflict with respect to the
use of its corporate name or any of its Proprietary Rights or of any facts
which indicate a likelihood of any of the foregoing. The validity of the
Proprietary Rights and the Company's or any Subsidiary's title thereto is not
being questioned in any suit, action, investigation, legal, administrative or
other proceeding to which the Company or any Subsidiary has been notified that
it is a party or, to the Company's knowledge, to which any other person is a
party nor, to the Company's knowledge, is any such suit, action,
investigation, legal, administrative or other proceeding threatened. None of
the computer software, computer firmware, computer hardware (whether general
or special purpose) or other similar or related items of automated,
computerized or software systems that are used or relied on by Company or by
any of its Subsidiaries in the conduct of their respective businesses will
malfunction, will cease to function, will generate incorrect data or will
produce incorrect results when processing, providing or receiving (i) date-
related data from, into and between the twentieth and twenty-first centuries
or (ii) date-related data in connection with any valid date in the twentieth
and twenty-first centuries, except where such malfunctions would not have a
Material Adverse Effect on the Company. The consummation of the Merger will
not adversely affect the Company's or any Subsidiary's title and interest in
and to the Proprietary Rights.

of the Company or any Subsidiary of any nature, whether absolute, accrued,
contingent or otherwise other than: (a) the liabilities and obligations

  filings, authorizations, orders and approvals as may be required to obtain
  the State Takeover Approvals, (iv) compliance with the HSR Act, and (v)
  Consents the failure of which to obtain or make would not have a Material
  Adverse Effect on the Parent or materially adversely affect the ability of
  the Parent or the Merger Sub to consummate the transactions contemplated
  hereby.
 
  Section 4.04 Information. None of the information supplied or to be supplied
by the Parent and the Merger Sub in writing specifically for inclusion in (i)
the Proxy Statement or (ii) the Other Filings will, at the respective times

Merger Sub, the Parent or their respective directors, officers, employees,
agents and representatives) with respect to any Acquisition Transaction or
enter into any agreement, arrangement or understanding requiring it to

contemplated by this Agreement; provided that the Company may, in response to

and negotiate or otherwise engage in substantive discussions with, the party
making such Favorable Third Party Proposal if the Board or Directors of the

a written proposal from a credible third party regarding the acquisition of
substantially all the capital stock of the Company, a merger, consolidation or

regarding a possible Acquisition Transaction. The Company shall immediately
advise the Parent in writing of the receipt, directly or indirectly, of any
inquiries or proposals relating to an Acquisition Transaction and any actions
taken pursuant to Section 5.09(a) and furnish to the Parent either a copy of
any such proposal or a written summary of any such proposal.

  party or group of related third parties become the beneficial owners of 50%
  or more of the outstanding voting securities of the Company (by a tender
  offer, exchange offer, stock issuance or otherwise), including any such
  transaction in which any of Werner E. Neuman, James A. Steinback or Carolyn
  A. Berry (each, a "Controlling Shareholder") or their affiliates
  participate, or (ii) the Merger is not consummated for any of the following
  reasons: (A) the Company's Board of Directors authorizes or recommends, or
  the Company enters into an agreement or agreement in principle or closes,
  an Acquisition Transaction (other than the Merger) or the Company's Board
  of Directors fails to recommend, or adversely modifies or withdraws its
  recommendation, to the Company's shareholders that they vote to approve the
  Merger as a result of Section 7.01(d), or takes any action to abandon or
  terminate this Agreement in accordance with Section 7.01(d), (B) a
  Controlling Shareholder or the Company fails to call a Shareholders'
  Meeting, or (C) the shareholders of the Company approve an Acquisition
  Transaction (other than the Merger), then the Company will promptly, but in
  no event later than three business days after the first of such events to
  occur, pay $2,000,000 to the Parent, plus an amount not to exceed $500,000
  for the transaction expenses incurred by the Merger Sub and the Parent.
 
    (b) The parties agree that the payment of the fees and expenses required
  pursuant to and in the manner set forth in this Section 5.10 is a material
  inducement to the Parent and the Merger Sub to enter into this Agreement
  and is intended to compensate the Parent and the Merger Sub for the
  opportunity costs and risks of entering into this Agreement.

March 10, 1998
 
Board of Directors
Corcom, Inc.
844 E. Rockland Road
Libertyville, IL 60048
 
Members of the Board:
 
  You have asked us to advise you with respect to the fairness to the
shareholders of Corcom, Inc. (the "Company"), from a financial point of view,
of the consideration to be received by such holders pursuant to the terms of
the Agreement and Plan of Merger, dated as of March 10, 1998 (the "Merger
Agreemen"), by and among the Company, Communications Instruments, Inc. ("CII")
and RF Acquisition Corp., a wholly-owned subsidiary of CII (the "Merger Sub").
The Merger Agreement provides for the merger of the Merger Sub with and into
the Company (the "Merger"), with the Company surviving the Merger and the
Merger Sub ceasing to exist. Each issued and outstanding share of common stock
of the Company, no par value per share (the "Company Common Stock") shall be
converted into the right to receive in cash an amount equal to $13.00 per
share (the "Merger Price").
 
  In connection with this opinion, we have, among other things: (a) reviewed
the Merger Agreement and certain related documents, (b) held discussions with
certain senior officers and other representatives and advisors of the Company
concerning the business, operations and prospects of the Company, (c) examined
certain publicly available business and financial information relating to the
Company as well as certain financial data and other data for the Company which
were provided to or otherwise discussed with us by the management of the
Company, and (d) reviewed the financial terms of the Merger as set forth in
the Merger Agreement in relation to, among other things: (i) current and
historical market prices and trading volumes of the Company Common Stock; (ii)
the Company's financial and other operating data; and (iii) the capitalization
and financial condition of the Company.
 
  We also considered, to the extent publicly available, the financial terms of
certain other similar transactions recently effected which we considered
relevant in evaluating the Merger and analyzed certain financial, stock market
and other publicly available information relating to the businesses of other
companies whose operations we considered relevant in evaluating those of the
Company.
 
  In rendering our opinion, we have, with your consent, assumed and relied
upon the accuracy and completeness of the financial and other information
reviewed by us and we have not made or obtained or assumed any responsibility
for independent verification of such information. In addition, with your
consent, we have not made or reviewed any independent evaluation or appraisal
of the assets and liabilities of the Company or any of its subsidiaries. With
respect to the financial data, we have assumed, with your consent, that it has
been reasonably prepared on bases reflecting the best currently available
estimates and judgments of the management of the Company as to the future
financial performance of the Company. We have further assumed, with your
consent, that the Merger will be consummated in accordance with the terms of
the Merger Agreement.
 
  There have been no recent public solicitations of indications of interest in
a possible acquisition of the Company. However, in connection with our
engagement, we approached a limited number of third parties to solicit
indications of interest in a possible acquisition of the Company and held
preliminary discussions with certain of these parties prior to the date
hereof.

  ABN AMRO Incorporated ("ABN AMRO"), as part of its investment banking
business, is continually engaged in the valuation of businesses in connection
with mergers and acquisitions, as well as public offerings and secondary
market transactions of securities and valuations for other purposes. We have
acted as financial advisor to the Board of Directors of the Company in
connection with this transaction and will receive a fee for our services,
including rendering this opinion, a significant portion of which is contingent
upon the consummation of the Merger. In the ordinary course of our business,
ABN AMRO and its affiliates may actively trade securities of the Company for
their own account and for the accounts of customers and, accordingly, may at
any time hold a long or short position in such securities.
 
  It is understood that this letter is for the benefit and use of the Board of
Directors of the Company in its consideration of the Merger and may not be
used for any other purpose or reproduced, disseminated, quoted or referred to
at any time, in any manner or for any purpose without our prior written
consent, except that this letter may be included and discussed in any proxy
statement of the Company relating to the Merger and that a copy of this letter
will be sent to CII and to Merger Sub pursuant to Section 3.27 of the Merger
Agreement. This letter does not address the Company's underlying business
decision to enter into the Merger or constitute a recommendation to any
shareholder as to how such shareholder should vote with respect to the
proposed Merger. Finally, our opinion is necessarily based on economic,
monetary, market and other conditions as in effect on, and the information
made available to us as of, the date hereof, and we assume no responsibility
to update or revise our opinion based upon circumstances or events occurring
after the date hereof.
 
  Based upon and subject to the foregoing, it is our opinion that, as of the
date hereof, the Merger Price to be received by the shareholders of the
Company in the Merger is fair to such shareholders from a financial point of
view.
 
                                          Very truly yours,
 
                                          ABN AMRO Incorporated

               DISSENTERS' APPRAISAL RIGHTS UNDER SECTIONS 11.65
                AND 11.70 OF THE ILLINOIS BUSINESS CORPORATION
                            ACT OF 1983, AS AMENDED
 
SECTION 11.65. RIGHT TO DISSENT
 
  Section 11.65. Right to Dissent. (a) A shareholder of a corporation is
entitled to dissent from, and obtain payment for his or her shares in the
event of any of the following corporate actions:
 
    (1) consummation of a plan of merger or consolidation or a plan of share
  exchange to which the corporation is a party if (i) shareholder
  authorization is required for the merger or consolidation or the share
  exchange by Section 11.20 or the articles of incorporation or (ii) the
  corporation is a subsidiary that is merged with its parent or another
  subsidiary under Section 11.30;
 
    (2) consummation of a sale, lease or exchange of all, or substantially
  all, of the property and assets of the corporation other than in the usual
  and regular course of business;
 
    (3) an amendment of the articles of incorporation that materially and
  adversely affects rights in respect of a dissenter's shares because it:
 
      (i) alters or abolishes a preferential right of such shares;
 
      (ii) alters or abolishes a right in respect of redemption, including
    a provision respecting a sinking fund for the redemption or repurchase,
    of such shares;
 
      (iii) in the case of a corporation incorporated prior to January 1,
    1982, limits or eliminates cumulative voting rights with respect to
    such shares; or
 
    (4) any other corporate action taken pursuant to a shareholder vote if
  the articles of incorporation, by-laws, or a resolution of the board of
  directors provide that shareholders are entitled to dissent and obtain
  payment for their shares in accordance with the procedures set forth in
  Section 11.70 or as may be otherwise provided in the articles, by-laws or
  resolution.
 
  (b) A shareholder entitled to dissent and obtain payment for his or her
shares under this Section may not challenge the corporate action creating his
or her entitlement unless the action is fraudulent with respect to the
shareholder or the corporation or constitutes a breach of a fiduciary duty
owed to the shareholder.
 
  (c) A record owner of shares may assert dissenters' rights as to fewer than
all the shares recorded in such person's name only if such person dissents
with respect to all shares beneficially owned by any one person and notifies
the corporation in writing of the name and address of each person on whose
behalf the record owner asserts dissenters' rights. The rights of a partial
dissenter are determined as if the shares as to which dissent is made and the
other shares were recorded in the names of different shareholders. A
beneficial owner of shares who is not the record owner may assert dissenters'
rights as to shares held on such person's behalf only if the beneficial owner
submits to the corporation the record owner's written consent to the dissent
before or at the same time the beneficial owner asserts dissenters' rights
 
SECTION 11.70. PROCEDURE TO DISSENT
 
  Section 11.70. Procedure to Dissent. (a) If the corporate action giving rise
to the right to dissent is to be approved at a meeting of shareholders, the
notice of meeting shall inform the shareholders of their right to dissent and
the procedure to dissent. If, prior to the meeting, the corporation furnishes
to the shareholders material information with respect to the transaction that
will objectively enable a shareholder to vote on the transaction and to
determine whether or not to exercise dissenters' rights, a shareholder may
assert dissenters' rights only if the shareholder delivers to the corporation
before the vote is taken a written demand for payment for his or her shares if
the proposed action is consummated, and the shareholder does not vote in favor
of the proposed action.
<PAGE>
 
  (b) If the corporate action giving rise to the right to dissent is not to be
approved at a meeting of shareholders, the notice to shareholders describing
the action taken under Section 11.30 or Section 7.10 shall inform the
shareholders of their right to dissent and the procedure to dissent. If, prior
to or concurrently with the notice, the corporation furnishes to the
shareholders material information with respect to the transaction that will
objectively enable a shareholder to determine whether or not to exercise
dissenters' rights, a shareholder may assert dissenter's rights only if he or
she delivers to the corporation 30 days from the date of mailing the notice a
written demand for payment for his or her shares.
 
  (c) Within 10 days after the date on which the corporate action giving rise
to the right to dissent is effective or 30 days after the shareholder delivers
to the corporation the written demand for payment, whichever is later, the
corporation shall send each shareholder who has delivered a written demand for
payment a statement setting forth the opinion of the corporation as to the
estimated fair value of the shares, the corporation's latest balance sheet as
of the end of a fiscal year ending not earlier than 16 months before the
delivery of the statement, together with the statement of income for that year
and the latest available interim financial statements, and either a commitment
to pay for the shares of the dissenting shareholder at the estimated fair
value thereof upon transmittal to the corporation of the certificate or
certificates, or other evidence of ownership, with respect to the shares, or
instructions to the dissenting shareholder to sell his or her shares within 10
days after delivery of the corporation's statement to the shareholder. The
corporation may instruct the shareholder to sell only if there is a public
market for the shares at which the shares may be readily sold. If the
shareholder does not sell within that 10 day period after being so instructed
by the corporation, for purposes of this Section the shareholder shall be
deemed to have sold his or her shares at the average closing price of the
shares, if listed on a national exchange, or the average of the bid and asked
price with respect to the shares quoted by a principal market maker, if not
listed on a national exchange, during that 10 day period.
 
  (d) A shareholder who makes written demand for payment under this Section
retains all other rights of a shareholder until those rights are canceled or
modified by the consummation of the proposed corporate action. Upon
consummation of that action, the corporation shall pay to each dissenter who
transmits to the corporation the certificate or other evidence of ownership of
the shares the amount the corporation estimates to be the fair value of the
shares, plus accrued interest, accompanied by a written explanation of how the
interest was calculated.
 
  (e) If the shareholder does not agree with the opinion of the corporation as
to the estimated fair value of the shares or the amount of interest due, the
shareholder, within 30 days from the delivery of the corporation's statement
of value, shall notify the corporation in writing of the shareholder's
estimated fair value and amount of the interest due and demand payment for the
difference between the shareholder's estimate of fair value and interest due
and the amount of the payment by the corporation or the proceeds of sale by
the shareholder, whichever is applicable because of the procedure for which
the corporation opted pursuant to subsection (c).
 
  (f) If, within 60 days from delivery to the corporation of the shareholder
notification of estimate of fair value of the shares and interest due, the
corporation and the dissenting shareholder have not agreed in writing upon the
fair value of the shares and interest due, the corporation shall either pay
the difference in value demanded by the shareholder, with interest, or file a
petition in the circuit court of the county in which either the registered
office or the principal office of the corporation is located, requesting the
court to determine the fair value of the shares and interest due. The
corporation shall make all dissenters, whether or not residents of this State,
whose demands remain unsettled parties to the proceeding as an action against
their shares and all parties shall be served with a copy of the petition.
Nonresidents may be served by registered or certified mail or by publication
as provided by law. Failure of the corporation to commence an action pursuant
to this Section shall not limit or affect the right of the dissenting
shareholders to otherwise commence an action as permitted by law.
 
  (g) The jurisdiction of the court in which the proceeding is commenced under
subsection (f) by a corporation is plenary and exclusive. The court may
appoint one or more persons as appraisers to receive evidence and recommend
decision on the question of fair value. The appraisers have the power
described in the order appointing them, or in any amendment to it.
<PAGE>
 
  (h) Each dissenter made a party to the proceeding is entitled to judgment
for the amount, if any, by which the court finds that the fair value of his or
her shares, plus interest, exceeds the amount paid by the corporation or the
proceeds of sale by the shareholder, whichever amount is applicable.
 
  (i) The court, in a proceeding commenced under subsection (f), shall
determine all costs of the proceeding, including the reasonable compensation
and expenses of the appraisers, if any, appointed by the court under
subsection (g), but shall exclude the fees and expenses of counsel and experts
for the respective parties. If the fair value of the shares as determined by
the court materially exceeds the amount which the corporation estimated to be
the fair value of the shares or if no estimate was made in accordance with
subsection (c), then all or any part of the costs may be assessed against the
corporation. If the amount which any dissenter estimated to be the fair value
of the shares materially exceeds the fair value of the shares as determined by
the court, then all or any part of the costs may be assessed against that
dissenter. The court may also assess the fees and expenses of counsel and
experts for the respective parties, in amounts the court finds equitable, as
follows:
 
    (1) Against the corporation and in favor of any or all dissenters if the
  court finds that the corporation did not substantially comply with the
  requirements of subsections (a), (b), (c), (d), or (f).
 
    (2) Against either the corporation or a dissenter and in favor of any
  other party if the court finds that the party against whom the fees and
  expenses are assessed acted arbitrarily, vexatiously, or not in good faith
  with respect to the rights provided by this Section.
 
  If the court finds that the services of counsel for any dissenter were of
substantial benefit to other dissenters similarly situated and that the fees
for those services should not be assessed against the corporation, the court
may award to that counsel reasonable fees to be paid out of the amounts
awarded to the dissenters who are benefited. Except as otherwise provided in
this Section, the practice, procedure, judgment and costs shall be governed by
the Code of Civil Procedure.
 
  (j) As used in this Section:
 
    (1) "Fair value", with respect to a dissenter's shares, means the value
  of the shares immediately before the consummation of the corporate action
  to which the dissenter objects excluding any appreciation or depreciation
  in anticipation of the corporate action, unless exclusion would be
  inequitable.
 
    (2) "Interest" means interest from the effective date of the corporate
  action until the date of payment, at the average rate currently paid by the
  corporation on its principal bank loans or, if none, at a rate that is fair
  and equitable under all the circumstances.

                                    PART I
 
ITEM 1. BUSINESS
 
  CORCOM, Inc. is an Illinois corporation incorporated in March, 1955. Except
as otherwise indicated by the context, references herein to "CORCOM" or the
"Company" mean CORCOM, Inc. and its subsidiaries. CORCOM's business consists
of the design, manufacture, and sale of radio frequency interference filters
to the commercial, facility, and military filter markets. The Company also
manufactures and sells a broad line of power entry devices that are used to
connect electronic equipment to an external power source.
 
PRODUCTS
 
  Radio frequency interference (RFI) filters are electronic components used to
protect electronic equipment from radio frequency interference conducted
through the AC power cord. They are also used to control the emission of the
RFI generated by electronic equipment so these emissions do not interfere with
other electronic devices. Customers purchase RFI filters for emission control
purposes to bring their equipment into compliance with government regulations
that limit the amount of radio frequency interference that can be emitted by
digital computing devices. The Company also manufactures a complete line of
Signal Sentrya products, filtered modular RJ jacks designed to solve RFI
problems on signal lines.
 
  CORCOM maintains a catalog of standard commercial filters that contains
approximately 500 designs, offering a variety of sizes, electrical
configurations, current ratings and environmental capabilities. These filters
consist of electronic circuits utilizing passive electrical components:
inductance coils, capacitors, and resistors. These are enclosed in a metal or
plastic case having terminals, lead wires, or an integral connector, for
attachment to associated equipment. Sales of commercial filters, including
Signal Sentrya products, accounted for approximately 72% of net sales in 1997,
75% in 1996, and 70% in 1995.
 
  CORCOM also manufactures and sells RFI filters for the military and facility
markets. Both product lines are similar to commercial filters in their basic
function and design. However, military filters are subject to extremely high
performance requirements as described by military specification. Facility
filters are larger versions of the Company's line of commercial filters and
are used to control RFI conducted through the main power line feeding secure
facilities. Together they represented 5% of 1997 sales, 4% of 1996 sales, and
5% of 1995 sales.
 
  The Company also distributes a line of power entry products that are used to
connect electronic equipment with a power source. These devices come in a
variety of configurations and may include an on-off switch, voltage selector,
fuse holder, and an IEC connector. Some power entry products also contain an
RFI filter. CORCOM's line of power entry products contains items of its own
design, plus some products obtained under a private label agreement. Sales of
power entry devices accounted for 23% of net sales in 1997, 21% in 1996, and
25% in 1995.
 
  In addition to filters and power entry products, the Company distributes a
variety of A/C power cords for use with filters and power entry products
having integral power connectors plus a series of line to line capacitors used
for RFI suppression.
 
  All of the Company's products are marketed under its federally registered
trademark, "CORCOM".
 
  CORCOM filters are designed to meet the requirements of one or more safety
and reliability specifications, such as those of Underwriters Laboratories
(UL), the Canadian Standards Association (CSA), the Verband Deutscher
Electrotechniker (VDE) in Germany, and the Schweizerischer Elektrotechnischer
Verein (SEV) in Switzerland.
 
  All CORCOM filters are designed and built to operate continuously for at
least five years when connected across a live A/C power line. CORCOM filters
must perform without interruption because in most cases they are energized
even when the equipment in which they are installed is switched off.
 
                                      D-2

MARKETS
 
  CORCOM power line RFI filters are used as electronic pollution control
devices by manufacturers of digital electronic equipment all over the world.
In addition, many filters are used by field service organizations for
installation in sensitive equipment which was manufactured without an
effective filter. Power entry products are sold into the same markets and
through the same channels of distribution. Military filters are sold to
defense contractors and U.S. government agencies for use in sensitive
electronic devices. Facility filters are sold principally to contractors for
installation in screen room test facilities, computer installations, or other
locations containing sensitive electronic equipment.
 
  Over 4,000 customers in the United States and more than 100 customers in
other countries purchased filters and power entry products from CORCOM or its
distributors in 1997. No single customer accounted for more than 10% of sales
in 1997, 1996, or 1995.
 
DISTRIBUTION
 
  Sales of CORCOM products in the United States are obtained by 18 independent
sales representative firms which call on major original equipment
manufacturers (OEM's), government contractors, U.S. government agencies, and
independent electronic parts distributors. There are 28 United States
distributor firms which carry the Company's products; these distributors
service the smaller OEM's and the service organizations. Both representatives
and distributors handle other types of products, and some distributors carry
competing lines.
 
  Export sales are conducted through combination representative/distributor
organizations. Representative sales are on a commission basis with shipments
directly to OEM's. On a distributor basis, filters and power entry products
are imported and sold to customers within their countries.
 
  The Company has 35 international representative/distributors plus wholly-
owned subsidiaries in Germany and Mexico. This network sold into 24 countries
in 1997. Primary export markets include Canada, Germany, the United Kingdom,
France, Italy, Spain, Sweden, Japan, South Korea, Taiwan, and Hong Kong.
International catalogs are published in German, Japanese, Malaysian, Chinese
and English. During 1997, the Company closed its direct sales office in Hong
Kong but continues to serve this market through local distributors. Total
international sales, which include the sales from Corcom's German subsidiary,
totaled $9,933,000 in 1997 (27.0% of net sales), $9,490,000 in 1996 (28.6% of
net sales) and $7,688,000 in 1995 (25.1% of net sales).
 
  Export sales from the United States are invoiced in United States dollars
while sales of the Company's German subsidiary are invoiced in German
Deutschmarks. All international sales are subject to factors such as changes
in foreign exchange rates, protective tariffs, tax policy and export/import
controls.
 
  CORCOM supports the marketing of its products by wide distribution of its
catalogs, by advertising in technical publications, and via an informational
internet site on the worldwide web. Advertising and catalog costs for the
Company were approximately $289,000, $284,000, and $209,000 in 1997, 1996, and
1995, respectively.
 
BACKLOG
 
  The Company's backlog of orders with firm delivery schedules was
approximately $8,260,000 on January 31, 1998, compared to $9,296,000 on
January 31, 1997. The backlog consists principally of special orders and
scheduled increments of volume contracts. Most catalog items are shipped from
inventory. Typical lead time for special orders is 12-14 weeks. Over 80% of
all orders are scheduled for delivery within 6 months. The Company does not
believe that its business is subject to seasonal variations.
 
COMPETITION
 
  Although industry statistics generally are not available, CORCOM believes
that in the United States it accounts for approximately 25% of commercial and
industrial power line interference filters, exclusive of military
applications. Competition principally includes Schaffner A.G. of Switzerland;
Delta of Taiwan;
 
                                      D-3
<PAGE>
 
Aerovox, Inc.; Stanford Applied Engineering, Inc.; as well as a number of
lesser participants. CORCOM believes that its sales volume is approximately
equal to the aggregate volume of its three principal United States
competitors. In Europe, the principal competitors are Schaffner A.G., Siemens,
Timonda and Eichoff. In the Far East CORCOM's principal competitor is Delta.
Many of the competitors are firms much larger than CORCOM, with far greater
financial resources, broader product lines and larger marketing organizations.
 
  CORCOM believes that its position in the commercial and industrial power
line interference filter market results from a number of factors, including
the Company's concentration on this market sector, its emphasis on application
engineering to meet individual customer requirements, its reputation for high
product reliability and quality, its broad catalog line, and its ability to
provide standard items from inventory and/or local distributor stock. The
Company believes that these factors have to date enabled CORCOM products to
achieve high acceptance in the marketplace.
 
  Because the Company's products are an integral part of the digital
electronic equipment produced by its OEM customers, there will always be the
possibility of a customer electing to produce its own RFI filters and power
entry products rather than purchase the Company's products.
 
  CORCOM's major competitor in power entry products is Schaffner A.G. of
Zurich, Switzerland. The Company believes that the two companies comprise
approximately half the market for these devices in the United States, with
each company having approximately the same market share.
 
PRODUCTION, TESTING, AND ASSEMBLY
 
  CORCOM's products are composed of electrical components such as capacitors
and inductors and connectors which are wired into specific circuit
configurations, soldered, assembled into metal or plastic housings, and
tested. Materials and components generally are available from multiple
sources, and loss of a particular supplier would not be expected to have a
materially adverse effect on the Company's operations.
 
ENGINEERING
 
  The Engineering Department is divided into four sections--Applications,
Catalog, Support, and Manufacturing Engineering. Applications Engineering
provides assistance to key OEM accounts as well as customers within specific
geographic regions. Catalog Engineering develops new products based on input
from Marketing, and maintains and improves existing catalog products through
new technologies. Support Engineering consists of Safety Engineering, which
ensures compliance with safety regulations worldwide, and Test Engineering,
which develops and maintains all testing and inspection equipment.
Manufacturing Engineering verifies that the necessary equipment, tooling and
processes are in place, and updates manufacturing on new and developing
techniques and processes. The costs associated with the Engineering Department
were $1,333,000 in 1997. This compares to $1,220,000 in 1996 and $1,247,000 in
1995.
 
ISO REGISTRATION
 
  CORCOM's manufacturing facilities were granted ISO 9001 registration in 1995
by Underwriters Laboratories. This registration validates a company's
management system to the internationally accepted ISO 9001 standard relative
to the design, manufacturing, and quality of the products it manufactures. ISO
registration is seen as a benefit to CORCOM's customers, as well as a vehicle
to promote a continuous improvement philosophy within the Company.
 
GOVERNMENT REGULATIONS
 
  The Federal Communications Commission (FCC) has adopted regulations to
reduce the interference potential of electronic equipment having circuitry
"that generates and uses timing signals or pulses at a rate in excess of
10,000 pulses (cycles) per second and uses digital techniques." This
definition includes essentially all
 
                                      D-4
<PAGE>
 
A/C powered computers and other digital equipment. Although the FCC has
exempted several specific types of devices, compliance with these rules has
been required for most types of A/C powered digital equipment since October,
1983.
 
  CORCOM believes that in most cases compliance with the FCC requirements will
require the suppression of conducted RFI through the use of power line
interference filters, and these are now considered a standard component in
most A/C powered digital electronic equipment.
 
  Outside the United States, RFI is controlled by national and regional
regulation. In Europe, the European Union (EU) has established directives to
control RFI which, in most respects, take into account the recommendations of
the special committee on radio interference (CISPR) of the International
Electrotechnical Commission (IEC). As of January 1, 1996, all electrical or
electronic products under the scope of the EU directives intended for sale or
distribution in the EU countries must display the CE marking for proof of
compliance with the EU specifications. These specifications in many respects
are similar to the FCC rules. It is therefore possible for a manufacturer
using a CORCOM filter to produce equipment in such a manner that it complies
with both FCC and international interference control regulations as well as
domestic and foreign safety requirements.
 
PATENTS
 
  The Company holds 11 patents. It may be possible for competitors of CORCOM
to copy aspects of its products even though the Company regards these as
proprietary. However, the Company believes that patent protection is of less
importance than the knowledge and experience of its management and personnel
and their ability to develop and market the Company's products. The Company
will apply for patents if and when it develops patentable processes or
products. The Company is not aware that the manufacture and sale of its
products, including those presently under development, require it to obtain
any licenses from others, although it may be necessary or desirable in the
future to obtain licenses for one or more of its future products.
 
EMPLOYEES
 
  On January 31, 1998, CORCOM had 672 full-time employees, of whom 576 were
engaged in production activities, 19 in product development and related
activities, 23 in sales and marketing, and 54 in general and administrative
capacities. The Company considers its employee relations to be excellent. The
Company has not experienced any work stoppage due to a labor dispute in over
31 years.
 
RECENT DEVELOPMENT
 
  On March 10, 1998 Corcom, Inc. (the "Registrant") entered into an Agreement
and Plan of Merger by and among Communications Instruments, Inc., a North
Carolina corporation ("ACII"), RF Acquisition Corp., an Illinois corporation
and wholly owned subsidiary of CII ("Merger Sub") and the Registrant (the
"Merger Agreement"). CII is owned by Code Hennessy & Simmons, LLC, a Chicago
based private investment firm, and CII management. Pursuant to the Merger
Agreement, (a) CII will acquire all of the Registrant's issued and outstanding
shares of common stock for $13.00 per share in cash, or approximately $51.2
million, and (b) Merger Sub will merge with and into Registrant (the
"Merger"), with Registrant being the surviving corporation in the Merger.
 
  The closing of the Merger is subject to the satisfaction of certain
conditions, including, among other matters, approval by the holders of two-
thirds of the issued and outstanding shares of common stock of the Registrant,
certain regulatory approvals and receipt by CII of debt financing necessary to
consummate the Merger, a commitment for which has been provided by Bank of
America National Trust and Savings Association. This financing is subject to
certain conditions, including the execution of a definitive credit agreement
satisfactory to Bank of America. A copy of the Merger Agreement is attached as
Exhibit 2.1 to the registrant's Current Report on Form 8-K (date of report
March 10, 1998) and is hereby incorporated by reference.
 
                                      D-5
<PAGE>
 
  CII also entered into an agreement with Werner E. Neuman, the President of
the Registrant, and James A. Steinback, a Director of the Registrant, whereby
such individuals agreed to vote in favor of the Merger. These two individuals
hold approximately 31% of the shares outstanding. A copy of this voting
agreement is attached as Exhibit 99.1 to the aforesaid Form 8-K and is hereby
incorporated by reference.
 
  A copy of the press release of the Registrant, dated March 11, 1998, is
attached as Exhibit 99.2 to the aforesaid Form 8-K and is hereby incorporated
by reference.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS.
 
  CORCOM's net sales for 1997 were $36,788,000, an increase of 10.9% from the
$33,166,000 reported for the previous year. The bulk of the increase came in
the form of a volume increase in the Company's North American commercial
filter business, the result of an increase in the overall electronics market.
There were no appreciable price changes year to year. Between 1995 and 1996,
sales increased 8.2%. Most of this increase came as a result of volume
increases in the Company's North American and European commercial filter
businesses. The increase in North America was the result of an increase in the
overall electronics market. The increase in Europe was principally
attributable to more stringent European RFI/EMI testing regulations which went
into effect January 1, 1996. There were no appreciable price changes in this
period either.
 
  The Company's backlog of orders with firm delivery schedules was $8,260,000
as of January 31, 1998, compared to $9,296,000 as of January 31, 1997 and
$10,346,000 on January 31, 1996. There has been a reduction in the last two
years of very long lead time orders by certain of the Company's customers;
however the value of orders deliverable in the upcoming 13 week period has
remained relatively constant over the last two years.
 
  In 1997 the Company's gross margins improved to 39.1% of sales from the
37.9% reported in 1996. This was primarily the result of cost reductions in
certain raw materials used by the Company, coupled with the
 
                                      D-7
<PAGE>
 
leveraging impact of higher production levels on the Company's fixed
production-related costs. The period 1995 to 1996 also showed an improvement
in gross margins from 37.1% in 1995 to 37.9% in 1996. This improvement was due
to a shift in mix to more profitable European sales partially offset by an
increase in the peso-based costs at the Company's Mexican production facility
as a result of the inflation in that currency during 1996. Since a portion of
the Company's costs are Mexican peso-based, should the value of that currency
increase relative to the dollar, or if inflation in Mexico escalates, the
Company's manufacturing costs could rise.
 
  Engineering expenses in 1997, at $1,333,000, were about 9.3% higher than the
$1,220,000 incurred in 1996, the result of resources added to this area in
1997 to keep up with rising demand. In 1996, engineering expenses were
approximately the same as they were in 1995. As a percent of revenue,
engineering expenses remained about the same in 1997, at 3.6% of sales, as
they were in 1996.
 
  Selling, administrative and other expenses were $545,000, or 7%, higher in
1997 than in 1996, the majority of which was due to higher commission and
sales expenses on the higher 1997 revenue and higher incentive compensation
costs on higher 1997 pretax income. Sales, administrative and other expenses
increased $704,000, or 10%, from 1995 to 1996. The major components of this
increase were higher sales commission and sales expenses on the higher levels
of sales in 1996.
 
  Interest expense was $10,000 in 1997 as compared with $16,000 and $71,000
for 1996 and 1995 respectively. Interest expense for 1997 and 1996 represents
the interest portion of lease payments on certain equipment leases only.
Interest expense for 1995 includes not only the interest portion of the
Company's lease payments, but interest expense on cash borrowings against the
Company's line of credit for a portion of that year. There have been no cash
borrowings since 1995.
 
  The Company recorded interest income from its cash and investments of
$306,000 in 1997. This was $172,000 higher than in 1996 as a result of the
increase in the Company's cash balances in this period. Interest income in
1996 was $127,000 higher than 1995, also the result of an increase in the
Company's level of cash.
 
  The Company's pre-tax earnings for 1997 were $5,013,000. This compares to
pre-tax earnings of $3,683,000 and $2,967,000 in 1996 and 1995 respectively.
The primary reasons for the improvement are discussed above.
 
  The Company recorded a provision for income tax expense of $2,010,000 in
1997. This represents approximately 40% of pretax earnings. In 1996, the
Company recorded a net income tax benefit of $1,789,000. The principal
component of this benefit was a $2,000,000 reversal of part of the valuation
allowance which existed as of December 31, 1995 as related to existing tax net
operating loss (NOL) carryforwards. Since it became apparent in 1996 that
there were no longer any uncertainties surrounding the ultimate utilization of
these NOL's, the valuation allowances against this deferred asset were
removed, resulting in the negative income tax expense in the period. In 1995,
the Company had recorded a minimal provision for income tax expense of
$181,000, or 6.1% of pretax earnings.
 
  The Company's net income after tax in 1997 was $3,003,000 ($.76 per share,
diluted). This compares to net earnings of $5,472,000 ($.1.38 per share,
diluted) and $2,786,000 ($.72 per share, diluted) in 1996 and 1995
respectively. The decrease from 1996 to 1997 is due to the effect of the 1996
tax credit described in the paragraph above. If both 1995 and 1996 earnings
were taxed at the full statutory 40% rate, proforma diluted earnings per share
for these two periods would have been $.46 and $.56, respectively. Weighted
average shares outstanding (diluted) for 1997 were 3,952,000, a decrease of
5,000 shares from the 3,957,000 weighted average shares outstanding reported
for 1996. The decrease was the net effect of the issuance of the 48,000 shares
on exercise of stock options by certain key employees in 1996, the dilutive
effect of existing unexercised stock options, and the purchase by the Company
throughout 1997 of 98,300 shares for the treasury. Weighted average shares
outstanding in 1996 were 3,957,000, an increase of 90,000 shares from the
3,867,000 reported in 1995. This increase was the joint result of the issuance
of 75,000 shares on exercise of stock options by certain key employees in
1996, and the dilutive effect of existing unexercised stock options.
 
                                      D-8

LIQUIDITY AND CAPITAL RESOURCES
 
  As of December 31, 1997, the Company had cash reserves on hand of $8,232,000
as compared with $4,789,000 cash on hand as of December 31, 1996. This cash is
invested in money-market, Eurodollar, and other conservative and liquid
vehicles. In addition to current cash reserves, the Company's loan agreement
with American National Bank and Trust Company of Chicago was renewed on
December 31, 1996 and is now in effect until April 30, 1998. This agreement is
an unsecured line of credit with maximum borrowings of $4,000,000, or 80% of
eligible accounts receivable, whichever is less. Interest on this loan is the
Company's choice of either LIBOR plus 150 basis points, or the Bank's prime
rate. There were no borrowings against this agreement as either December 31,
1997 or 1996.
 
  As of December 31, 1997, the Company had foreign income tax carryforwards of
$1,894,000, principally in Hong Kong, Mexico and the West Indies.
Approximately $1,485,000 of the foreign NOL carryforwards have no expiration
date. The company had no domestic income tax NOL carryforwards remaining as of
December 31, 1997.
 
  Management feels that existing cash balances and the existing bank line of
credit will be sufficient to support its cash needs through 1998.
 
  In 1997, the Company began converting its computer systems to be year 2000
compliant. Most of the Company's business software consists of externally
written, generic "packages" which have already been upgraded to be year 2000
compliant by their publishers. These upgraded versions have been made
available to the Company as part of its normal software licensing and/or
maintenance agreements. In certain cases, installation of the upgraded systems
may require additional purchased hardware or software which would be recorded
as assets and amortized. In addition to its main purchased business software,
but to a much lesser extent, the Company also has some internally developed
systems and subsystems which are in the process of being made year 2000
compliant. The Company does not believe it will encounter any material
problems with this conversion. Management does not feel that the cost of this
conversion will be material.

preceding sentence.

  We have audited the consolidated financial statements and related financial
statement schedules of Corcom, Inc. and Subsidiaries listed in the index on
page F-1 of this Form 10-K. These financial statements are the responsibility
of the Company's management. Our responsibility is to express an opinion on
these financial statements and related schedules based on our audits.
 
  We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements and related
schedules are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements and related schedules. An audit also includes assessing the
accounting principles used and significant estimates made by management, as
well as evaluating the overall financial statement presentation. We believe
that our audits provides a reasonable basis for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Corcom, Inc.
and Subsidiaries as of December 31, 1997 and 1996 and the consolidated results
of their operations and their cash flows for each of the years in the three
year period ended December 31, 1997 in conformity with generally accepted
accounting principles. In addition, in our opinion, the financial statement
schedules referred to above, when considered in relation to the basic
financial statements taken as a whole, present fairly, in all material
respects, the information required to be included herein.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Principles of Consolidation
 
  The consolidated financial statements include the accounts of Corcom, Inc.
and its wholly-owned subsidiaries (the Company). Intercompany accounts and
transactions have been eliminated in consolidation.
 
 Cash Equivalents
 
  The Company considers all highly liquid investments with original maturities
of three months or less as cash equivalents.
 
 Inventories
 
  Inventories are stated at the lower of cost or market. The first-in, first-
out method is used to determine cost.
 
 Property, Plant and Equipment
 
  Property, plant and equipment are stated at cost. Depreciation is computed
principally by the straight-line method over the estimated useful lives of the
related assets or terms of the related leases for leasehold improvements, if
shorter. Estimated useful lives range from three to eight years.
 
  Amounts incurred for maintenance and repairs are charged to operations as
incurred. Expenditures for improvements are capitalized. Upon sale or
retirement, the related cost and accumulated depreciation are removed from the
respective accounts and any resulting gain or loss is included in the
consolidated statements of income.
 
 Treasury Stock
 
  In March, 1997 the board of directors authorized the repurchase, at
management's discretion, of up to 200,000 shares of the Company's stock.
Shares repurchased under this authorization were used to offset the dilution
caused by the Company's employee stock option plan. The Company's repurchases
of shares of common stock are recorded as "Treasury Stock" and result in a
reduction of "Stockholders' Equity."
 
 Income Taxes
 
  Income taxes are accounted for in accordance with SFAS No. 109, "Accounting
for Income Taxes." The Company recognizes deferred tax liabilities and assets
for the expected future tax consequences of events that have been included in
the financial statements or tax returns. Under this method, deferred income
taxes are recorded to reflect the tax consequences on future years of
differences between the basis of assets and liabilities for income tax and for
financial reporting purposes using enacted tax rates in effect for the year in
which the differences are expected to reverse. In addition, the amounts of any
future tax benefits are reduced by a valuation allowance to the extent such
benefits are not expected to be fully realized.
 
 Translation of Foreign Currencies
 
  The Company measures foreign assets, liabilities, equity, and results of
operations in the functional currencies of the countries in which it operates
except for its operations in Mexico for which the U.S. dollar is the
functional currency. The Company translates foreign currency financial
statements by translating balance sheet accounts at the current exchange rate
in effect at year-end and income statement accounts at the average exchange
rates during the year.
 
  Translation adjustments result from the process of translating foreign
currency financial statements into U.S. dollars. These translation
adjustments, which are generally not included in the determination of net
income, are reported separately as a component of stockholders' equity.

 Revenue Recognition
 
  Sales to customers are recorded at the time of shipment net of estimated
discounts and allowances.
 
 Earnings per Share
 
  In 1997, the Financial Accounting Standards Board issued Statement No. 128,
"Earnings per Share." Statement 128 replaced the calculation of primary and
fully diluted earnings per share with basic and diluted earnings per share.
Unlike primary earnings per share, basic earnings per share excludes any
dilutive effects of stock options. Diluted earnings per share is very similar
to the previously reported fully diluted earnings per share. All earnings per
share amounts for all periods have been presented, and where appropriate,
restated to conform to the Statement 128 requirements.
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
 New Accounting Pronouncements
 
  The Company will implement the provisions of Statement of Financial
Accounting Standards No. 130, "Reporting Comprehensive Income Summary" (SFAS
130) for financial statements issued for fiscal years beginning after December
15, 1997. SFAS 130 establishes standards for reporting and display of
comprehensive income and its components (revenues, expenses, gains and losses)
in a full set of general-purpose financial statements. Management does not
believe this statement will have a material impact on its financial
statements.
 
  The Company will implement the provisions of Statement of Financial
Accounting Standard No. 131, "Disclosures about Segments of an Enterprise and
Related Information" (SFAS 131) for financial statements issued for periods
beginning after December 15, 1997. SFAS 131, which is based on the management
approach to segment reporting, includes requirements to report selected
segment information quarterly and entity-wide disclosures about products and
services, major customers, and the material countries in which the entity
holds assets and reports revenues. Management does not believe this statement
will have a material impact on its financial statements.
 
  Statement of Financial Accounting Standards No. 132, "Employers' Disclosures
about Pensions and Other Postretirement Benefits" (SFAS 132), effective for
fiscal years beginning after December 15, 1997, standardizes the disclosure
requirements for pensions and other postretirement benefits, requires
additional information on changes in the benefit obligation and fair values of
plan assets and eliminates certain disclosures that are no longer useful.
Management has yet to determine the impact of this pronouncement on its
financial statements.

  As of December 31, 1997, the Company maintained a valuation allowance with
respect to the deferred tax asset as a result of the uncertainty of ultimate
realization of foreign NOL carryforwards. The Company had foreign income tax
carryforwards of $1,894,000, principally in Hong Kong, Mexico and the West
Indies. Approximately $1,485,000 of the foreign NOL carryforwards have no
expiration date.
 
6. EMPLOYEE BENEFIT PLANS
 
  The Company has established certain stock-based compensation plans,
described below, for the benefit of certain officers, key employees, and
directors. The Company accounts for these plans under APB Opinion No. 25,
"Accounting for Stock Issued to Employees" (APB 25) and related
Interpretations. Accordingly, no compensation expense has been recognized
related to these plans. Under Statement of Financial Accounting Standards No.
123, "Accounting for Stock-Based Compensation" (SFAS 123), compensation
expense is measured based on the fair value method. The Company has adopted
the disclosure-only provisions of SFAS 123.
 
  The Company has stock option plans which provide for the granting of options
to certain officers, key employees, and directors. The option price per share
is not less than the market price at the date of grant. Options granted under
the officer and key employee plan become exercisable at 40% one year from date
of grant and an additional 20% per year thereafter. Options granted under the
directors' plan become exercisable six months after date of grant. All
unexercised options expire five years after the date of grant.
 
  The fair value of each option granted is estimated on the date of grant
using the Black-Scholes option pricing model with the following assumptions:
(1) expected volatility of 57.6%, (2) risk-free interest rate of 6.9% in 1995
and 5.9% in 1994, and (3) expected life of 4.13 to 4.26 years. The Company has
declared no cash dividends during 1997, 1996, and 1995.
 
  There were no stock options granted in 1997. The weighted average fair value
of stock options, calculated using the Black-Scholes option pricing model,
granted during 1996 and 1995, respectively, was $3.68 and $1.63. Had the
Company elected to apply the provisions SFAS 123 regarding recognition of
compensation expense to

SUBSEQUENT EVENT [UNAUDITED]
 
  On March 10, 1998 the Company entered into an Agreement and Plan of Merger
by and among Communications Instruments, Inc., a North Carolina corporation
("CII"), RF Acquisition Corp., an Illinois corporation and wholly owned
subsidiary of CII ("Merger Sub") and the Company (the "Merger Agreement"). CII
is owned by Code Hennessy & Simmons, LLC, a Chicago based private investment
firm, and CII management. Pursuant to the Merger Agreement, (a) CII will
acquire all of the Company's issued and outstanding shares of common stock for
$13.00 per share in cash, or approximately $51.2 million, and (b) Merger Sub
will merge with and into the Company (the "Merger"), with the Company being
the surviving corporation in the Merger.
 
  The closing of the Merger is subject to the satisfaction of certain
conditions, including, among other matters, approval by the holders of two-
thirds of the issued and outstanding shares of common stock of the Company,
certain regulatory approvals and receipt by CII of debt financing necessary to
consummate the Merger, a commitment for which has been provided by Bank of
America National Trust and Savings Association. This financing is subject to
certain conditions, including the execution of a definitive credit agreement
satisfactory to Bank of America.
 
  CII also entered into an agreement with Werner E. Neuman, the President and
Chairman of the Board of Directors of the Company, and James A. Steinback, a
Director of the Company, whereby such individuals agreed to vote in favor of
the Merger. These two individuals hold approximately 31% of the shares
outstanding.

Mr. Werner E. Neuman
President
Corcom, Inc.
844 East Rockland Road
Libertyville, IL 60048-3375
 
Dear Mr. Neuman:
 
  The Chicago Dearborn Company ("Chicago Dearborn") is pleased to set forth
the terms of this engagement letter agreement (the "Agreement") relating to
its retention for financial advisory services by Corcom, Inc. ("Corcom").
 
  1. Description of Engagement. Chicago Dearborn agrees to act as the
exclusive financial advisor and agent for Corcom to provide financial advisory
and investment banking services in connection with a financial evaluation of
Corcom and a review of financial and strategic alternatives.
 
  The terms of this Agreement shall extend from the date of this letter for a
period of twelve months thereafter, and may be extended on a quarter-to-
quarter basis by mutual written consent of the parties hereto, hereinafter
referred to as the "Term."
 
  2. Services to be Provided. In connection with its financial evaluation of
Corcom, a review of financial and strategic alternatives and a Transaction, as
defined herein, Chicago Dearborn will, or will stand ready to:
 
    Review the businesses, operations and assets of Corcom; Analyze the
  historical and projected financial performance of Corcom;
 
    Prepare an information package describing the business and prospects of
  Corcom;
 
    Formulate a strategy for discussions and negotiations with potential
  partners;
 
    Compile a list of potential partners and, at Corcom's request, contact
  potential partners to present the opportunity and distribute the
  information package;
 
    Coordinate and assist in due diligence meetings with potential partners;
 
    Assist in the negotiations and execution of a definitive purchase
  agreement pursuant to a Transaction, as defined herein;
 
    Render an opinion to the Board of Directors of Corcom, if requested, as
  to the fairness of any Transaction, as defined herein, to the shareholders
  of Corcom from a financial point of view; and
 
    Provide, as deemed appropriate by Chicago Dearborn, additional financial
  advisory services related to a Transaction, as defined herein.
 
  3. Compensation. In consideration of Chicago Dearborn providing, or standing
ready to provide, the financial advisory services described in paragraph 2
above, Corcom agrees to pay to Chicago Dearborn the following:
 
    a) a non-refundable Retainer of $25,000 per quarter, due and payable in
  advance, with the first quarter payable upon signing of this Agreement, and
  with such Retainer to be credited against any Financial Advisory Fee
  payable pursuant to paragraph 3b below, and
 
                                     D-33
<PAGE>
 
    b) in the event there is a transaction or series of transactions
  ("Transaction") whereby, directly or indirectly, control or a material
  interest in the stock or assets of Corcom is transferred for consideration,
  including, without limitation, by means of a merger, consolidation, sale of
  assets, sale of stock, stock or rights offering, tender or exchange offer,
  leveraged buyout, the formation of a joint venture or partnership,
  recapitalization, restructuring, business combination or investment by
  another entity involving Corcom, Corcom agrees to pay Chicago Dearborn a
  Financial Advisory Fee equal to:
 
      (i) $150,000 on the first $10.0 million of the Transaction Value, as
    defined in paragraph 4 below, and
 
      (ii) 1.50% of the Transaction Value, as defined in paragraph 4 below,
    in excess of $10.0 million.
 
    c) If so requested by the Board of Directors of Corcom, Chicago Dearborn
  shall render one or more opinions ("Opinions"), verbal or written,
  regarding the terms of any proposed Transaction, from a financial point of
  view. In such an event, Corcom will pay Chicago Dearborn a one time opinion
  fee (the "Opinion Fee") of $100,000 in cash upon delivery of the first of
  such Opinions. Corcom agrees that (a) the Opinions shall be used solely by
  the Board of Directors of Corcom, including any Committee thereof, in
  considering the terms of the proposed Transaction and (b) Corcom shall not
  furnish the Opinions or any summaries or excerpts thereof to any other
  person or persons or use the Opinions for any other purpose without the
  prior written approval of Chicago Dearborn; provided, however, that in any
  event, Corcom is hereby authorized to use or introduce into evidence or
  otherwise refer to the Opinions in connection with any litigation relating
  to the proposed Transaction or as otherwise required, in the reasonable
  judgment of counsel for Corcom, by law. Corcom also may, in its discretion,
  publish or refer to the Opinions in any proxy statement or otherwise in
  connection with the proposed Transaction, so long as Chicago Dearborn gives
  its prior written consent to such publication or reference, which consent
  shall not be unreasonably withheld. The Opinion Fee shall be credited
  against the Financial Advisory Fee payable under paragraph 3b above.
 
  Subject to the provisions set forth in paragraph 11 herein, this Financial
Advisory Fee shall be payable in immediately available funds on the closing
date of a Transaction regardless of whether such closing occurs during the
Term or such Transaction is initiated during the Term and is closed within
nine months of the Term. Corcom's obligation to pay the Financial Advisory Fee
shall be contingent solely upon closing of a Transaction. The Financial
Advisory Fee shall not include any fees earned by Chicago Dearborn or others
for furnishing services other than as provided herein, such as fees payable in
connection with the placement or arrangement of any debt or equity financing
necessary to consummate a Transaction or advisory work unrelated to the
Transaction including, without limitation, advisory fees associated with any
divestitures of assets by Corcom following a Transaction.
 
  4. Definition of Transaction Value. "Transaction Value" shall be defined as
the total consideration paid for the stock (including stock options or stock
issuable pursuant to stock options) or assets of Corcom and will be the sum of
all cash, the market value of any securities issued (if the securities are not
readily marketable, the market value will be established at fair value or by
mutual agreement) as consideration towards the purchase of such stock or
assets, the present value of (i) any non-compete payments payable pursuant to
a Transaction, (ii) any post-closing adjustments, (iii) any contingent future
payments (such amounts to be determined in good faith negotiations between
Corcom and Chicago Dearborn) using a discount rate of 10% per annum, and the
unpaid principal amount of any funded-debt obligation (debt for borrowed money
including, without limitation, any interest-bearing debt or capitalized lease
obligation) of Corcom assumed or discharged pursuant to a Transaction, or in
the case of a purchase of stock of Corcom, the amount of such obligations at
the time of closing of a Transaction.
 
  5. Expenses. In addition to the Financial Advisory Fee and Retainer
described in paragraph 3 above, Corcom agrees to promptly reimburse Chicago
Dearborn, upon request, for all reasonable travel and external legal fees and
other out-of-pocket expenses incurred in performing the financial advisory
services hereunder regardless of whether a Transaction is consummated. Corcom
will not reimburse out-of-pocket expenses in excess of $20,000 without having
granted its prior approval, provided such approval will not be unreasonably
withheld.
 
 
                                     D-34
<PAGE>
 
  6. Indemnification. Corcom agrees to: (i) indemnify and hold harmless
Chicago Dearborn, its directors, officers, agents, employees, and any
individual(s) who may be deemed to control Chicago Dearborn (collectively
"Indemnified Persons") against all losses, claims, damages, penalties,
judgments, liabilities and expenses of every kind whatsoever (including,
without limitation, all reasonable expenses of litigation or preparation
therefor, including reasonable attorney's fees, whether or not an Indemnified
Person is a party thereto) (collectively, "Liabilities"), which any of the
Indemnified Persons may pay or incur arising out of or relating to this
Agreement or the Transaction; and (ii) expressly and irrevocably waive any and
all rights and objections which it may have against any Indemnified Persons in
respect of any Liabilities arising out of or relating to this Agreement or the
Transaction, except, in each case, to the extent that such Liabilities arise
primarily from an Indemnified Person's gross negligence or willful misconduct.
 
  Corcom further agrees not to settle any claim, litigation or proceeding
(whether or not any Indemnified Person is a party thereto) relating to this
Agreement or Transaction without Chicago Dearborn's prior written consent
unless: (i) such settlement releases all the Indemnified Persons from any and
all Liabilities related to this Agreement or the Transaction; and (ii) the
entire settlement amount and all costs of settlement are borne by Corcom.
 
  An Indemnified Person shall have the right to employ his own counsel in any
suit, action or proceeding arising from the Agreement or the Transaction if
the Indemnified Person reasonably concludes, based on advice of counsel, that
a conflict of interest exists between Corcom and the Indemnified Person which
would materially impact the effective representation of the Indemnified
Person. In the event that the Indemnified Person concludes that such a
conflict of interest exists, the Indemnified Person shall have the right to:
(i) assume and direct the defense of such suit, action, or proceeding on his
own behalf; and (ii) to select counsel which will represent him in any such
action, suit or proceeding, and Corcom shall indemnify the Indemnified Person
for the reasonable legal fees and expenses of such counsel and other out-of-
pocket expenses reasonably incurred by the Indemnified Person.
 
  7. Referral. Corcom acknowledges that, although The First National Bank of
Chicago (the "Bank") has referred Corcom to Chicago Dearborn, neither the Bank
nor any of its affiliates, officers, directors or employees shall have any
responsibility or liability of any kind whatsoever in connection with the
services rendered pursuant to this Agreement. Furthermore, Corcom acknowledges
that Chicago Dearborn is not an affiliate of the Bank.
 
  8. Persons Entitled to Reliance. Corcom recognizes that Chicago Dearborn has
been retained only by the undersigned, and that its engagement of Chicago
Dearborn is not deemed to be on behalf of and is not intended to confer rights
upon any shareholder, owner or partner of Corcom or any other person not a
party hereto as against Chicago Dearborn or any of Chicago Dearborn's
affiliates, the respective directors, officers, agents and employees of
Chicago Dearborn's affiliates or each other person, if any, controlling
Chicago Dearborn or any of Chicago Dearborn's affiliates. Unless otherwise
expressly stated in an opinion letter issued by Chicago Dearborn or otherwise
expressly agreed to by Chicago Dearborn, no one other than Corcom is
authorized to rely upon this engagement of Chicago Dearborn or any statements
or conduct by Chicago Dearborn.
 
  9. Cooperation. In connection with Chicago Dearborn's activities pursuant to
this Agreement, Corcom will cooperate with Chicago Dearborn and will, to the
extent possible, furnish Chicago Dearborn with all information and data
concerning the Transaction and Corcom which Chicago Dearborn deems appropriate
and will, to the extent possible, provide Chicago Dearborn with access to
Corcom's respective officers, directors, employees, financial advisors,
independent accountants and legal counsel. Corcom represents and warrants that
all information made available to Chicago Dearborn by Corcom or contained in
any filing by Corcom with any court or governmental regulatory agency,
commission or instrumentality with respect to any Transaction will, at all
times during the period of the engagement of Chicago Dearborn hereunder, be
complete and correct in all material respects and will not contain any untrue
statement of a material fact or omit to state a material fact necessary in
order to make the statements therein not misleading in the light of the
circumstances under which such statements are made. Corcom further represents
and warrants that any projections provided by it to Chicago Dearborn will have
been prepared in good faith and will be based upon assumptions which, in light
of the circumstances under which they are made, are reasonable. Corcom
acknowledges and agrees that, in rendering
 
                                     D-35
<PAGE>
 
its services hereunder, Chicago Dearborn will be using and relying on
information provided by Corcom or information available from public sources
and other sources deemed reliable by Chicago Dearborn without independent
verification thereof by Chicago Dearborn or independent appraisal by Chicago
Dearborn. Chicago Dearborn does not assume responsibility for the accuracy or
completeness of any of this information regarding Corcom.
 
  10. Confidentiality
 
    a) Chicago Dearborn agrees to keep confidential non-public information
  which it receives from Corcom concerning Corcom and the Transaction and to
  disclose that information only with the consent of Corcom or as required by
  law or legal process.
 
    b) Corcom agrees to keep confidential non-public information which it
  receives from Chicago Dearborn (including, without limitation, opinions and
  advice) and to disclose that information only with the consent of Chicago
  Dearborn; provided that Corcom may disclose the fact that it has retained
  Chicago Dearborn as an advisor, and as required by regulation, law or legal
  process.
 
TERMINATION
 
  This Agreement shall become effective upon Corcom's acceptance of this
letter. This Agreement may be terminated during the Term by either Chicago
Dearborn or Corcom giving thirty days prior written notice of termination to
the other. Neither termination of this Agreement nor consummation of the
Transaction contemplated herein shall affect i) any compensation earned by
Chicago Dearborn up to and including the date of termination or consummation;
ii) the reimbursement of expenses incurred by Chicago Dearborn up to the date
of termination or consummation; and iii) paragraphs 3-12, inclusive, of this
Agreement. If this Agreement is terminated by Corcom or this Agreement is
terminated by Chicago Dearborn after a breach of the Agreement by Corcom or
the Agreement's Term expires without renewal, and if a Transaction is
consummated during the period of nine months following a termination for any
of the three foregoing reasons, then the Financial Advisory Fee in respect of
such Transaction shall become due and payable. Notwithstanding anything to the
contrary contained herein, Chicago Dearborn shall not be entitled to any
Financial Advisory Fee pursuant to this Agreement if Chicago Dearborn
terminates this Agreement, other than termination due to Corcom's breach of
terms of this Agreement.
 
  12. Miscellaneous.
 
    a) Corcom may not assign this Agreement. Chicago Dearborn may not assign
  this Agreement to any party other than a related affiliate.
 
    b) Corcom agrees that, upon consummation of a Transaction, Chicago
  Dearborn has the right to publish a tombstone advertisement in financial
  publications at its own expense describing its services hereunder.
 
    c) The Agreement represented by this letter shall be governed by the laws
  of the State of Illinois.
 
  Please confirm that the foregoing is in accordance with your understanding
of this Agreement by signing and returning to us a copy of this letter.

NOTE E--MERGER
 
  On March 10, 1998, the Company entered into an Agreement and Plan of Merger
by and among Communications Instruments, Inc., a North Carolina corporation
("CII"), RF Acquisition Corp., an Illinois corporation and wholly owned
subsidiary of CII ("Merger Sub") and the Company (the "Merger Agreement"). CII
is owned by Code Hennessy & Simmons, LLC, a Chicago based private investment
firm, and CII management. Pursuant to the Merger Agreement, (a) CII will
acquire all of the Company's issued and outstanding shares of common stock for
$13.00 per share in cash, or approximately $51.2 million, and (b) Merger Sub
will merge with and into the Company (the "Merger"), with the Company being
the surviving corporation in the Merger.
 
  The closing of the Merger is subject to the satisfaction of certain
conditions, including, among other matters, approval by the holders of two-
thirds of the issued and outstanding shares of common stock of the Company,
certain regulatory approvals and receipt by CII of debt financing necessary to
consummate the Merger, a commitment for which has been provided by Bank of
America National Trust and Savings Association. This financing is subject to
certain conditions, including the execution of a definitive credit agreement
satisfactory to Bank of America.
 
  CII also entered into an agreement with Werner E. Neuman, the President and
Chairman of the Board of Directors of the Company, and James A. Steinback, a
Director of the Company, whereby such individuals agreed to vote in favor of
the Merger. These two individuals hold approximately 31% of the shares
outstanding.

  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
                                  OPERATIONS.
 
RESULTS OF OPERATIONS--FIRST QUARTER 1998 VS. FIRST QUARTER 1997
 
  CORCOM's net sales for the first quarter of 1998 were $9,385,000, an
increase of 4.4% from the $8,993,000 reported for the first quarter of 1997.
This increase was the result of volume increases in the Company's North
American commercial filter business. There were no appreciable price changes
year to year.
 
  Cost of sales for the current quarter were 62.5% of net sales, about the
same as the year ago period. A portion of the Company's manufacturing costs
are Mexican peso-based. While this currency has been relatively stable over
the past year versus the US dollar, the Company's manufacturing costs could
rise if the value of the peso increases relative to the dollar, or if
inflation in Mexico escalates.
 
  Engineering expenses, at $425,000 in the first quarter of 1998, were 26%
higher than the $338,000 reported in the first quarter of 1997, the result of
an increased commitment to new product development. Selling, administrative
and other expenses rose in 1998 to $2,042,000 from the $1,976,000 reported in
the first quarter of 1997. The largest component of this increase were higher
commission expenses on the higher level of sales volume.
 
  Interest income in first quarter of 1998 period was $114,000 compared with
$49,000 in the first quarter of 1997. This was the result of higher cash
investments in the 1998 period.
 
  The Company's pre-tax earnings for the first quarter of 1998 were $1,168,000
as compared with $1,101,000 for the first quarter of 1997. The reasons for the
improvement are discussed above.
 
  The Company recorded a provision for income taxes of $468,000, or 40% of
pretax income, in the first quarter of 1998 as compared to a provision of
$360,000, or 33% of pretax income, in the first quarter of 1997.
 
  After tax, the Company's net earnings for the first quarter of 1998 were
$700,000 ($.19 per share basic, $.18 per share diluted). This compares to net
earnings in the year ago period of $741,000 ($.19 per share basic, $.19 per
share diluted).
 
LIQUIDITY AND CAPITAL RESOURCES
 
  As of April 4, 1998, the company had cash reserves on hand of $8,151,000 as
compared to $8,232,000 as of December 31, 1997. In addition to current cash
reserves, the Company's loan agreement with American National Bank and Trust
Company of Chicago is still in place. This agreement is an unsecured line of
credit with maximum borrowings of $4,000,000, or 80% of eligible accounts
receivable, whichever is less. Interest on this loan is the Company's choice
of either LIBOR plus one hundred fifty basis points, or the Bank's prime rate.
This agreement, which was to have expired April 30, 1998, has been extended
through June 30, 1998 (see exhibit 10.1). There were no borrowings against
this agreement as of April 4, 1998.
 
  The Company does not believe it will need to identify additional sources of
capital over the next year and feels that current cash reserves, cash provided
by operating activities, and the existing credit facility will be sufficient
to meet its operating needs and capital resource requirements.
 
YEAR 2000 ISSUES
 
  In 1997, the Company began converting its computer systems to be year 2000
compliant. Most of the Company's business software consists of externally
written, generic "packages" which have already been upgraded to be year 2000
compliant by their publishers. These upgraded versions have been made
available to the Company as part of its normal software licensing and/or
maintenance agreements. In certain cases, installation of the upgraded systems
may require additional purchased hardware or software which would be recorded
as assets and amortized. In addition to its main purchased business software,
but to a much lesser extent, the Company also has some internally developed
systems and subsystems which are in the process of being made year 2000
compliant. The company does not believe it will encounter any material
problems with this conversion. Management does not feel that the cost of this
conversion will be material.

              AMERICAN NATIONAL BANK AND TRUST COMPANY OF CHICAGO
 
                   REVOLVING LINE OF CREDIT NOTE (UNSECURED)
 
$4,000,000.00                  Chicago, Illinois                 April 30, 1998
                                                             Due: June 30, 1998
 
  For Value Received, the undersigned jointly and severally (if more than one)
("Borrower"), promises to pay to the order of American National Bank and Trust
Company of Chicago ("Bank"), at its principal place of business in Chicago,
Illinois or such other place as Bank may designate from time to time
hereafter, the principal sum of FOUR MILLION AND NO/100 DOLLARS
($4,000,000.00) or such lesser principal sum as may then be owed by Borrower
to Bank hereunder, such payment to occur on June 30, 1998. Borrower's
obligations under this Note shall be defined and referred to herein as
"Borrower's Liabilities".
 
  This Note restates and replaces a Revolving Line of Credit Note in the
principal amount of $4,000,000.00, dated December 31, 1996 executed by
Borrower in favor of Bank (the "Prior Note") and is not a repayment or
novation of the Prior Note.
 
  Borrower may prepay all or part of the principal, together with accrued
interest on the amount so prepaid, without penalty during the term of the
Note. All prepayments shall be applied upon installments of the most remote
maturity.
 
  The principal amount of this Note is available to the Borrower on a
revolving basis. The undersigned may borrow, repay and reborrow any amount,
subject to the limitations contained in the Loan Agreement dated December 27,
1995, as amended from time to time, executed by and between Corcom, Inc. and
Bank (the "Loan Agreement"), provided that the total outstanding principal
balance does not exceed the principal amount of this Note and that Borrower
has complied with all the terms of this Note and the Loan Agreement. The books
and records of the Bank shall be determinative of the unpaid balance of this
Note from time to time outstanding, absent manifest error.
 
  Reference is hereby made to the Loan Agreement for a statement of the terms
and conditions under which the loan evidenced hereby has been made, is to be
repaid and for a statement of Bank's remedies upon the occurrence of an "Event
of Default" as defined in the Loan Agreement. The terms and conditions of the
Loan Agreement are incorporated herein by reference in their entirety.
 
  Borrower's Liabilities unpaid from time to time shall bear interest
(computed on the basis of a 360-day year and actual days elapsed) from the
date hereof until paid at a per annum rate at all times equal to the Bank's
Base Rate or equivalent as announced or published publicly from time to time
(the "Base Rate"). Therefore, interest shall be calculated for each day at
1/360th of the applicable per annum rate. The Base Rate is not indicative of
the lowest or best rate offered by the Bank to any customer or group of
customers. A change in the Base Rate shall constitute a corresponding change
in the interest rate hereunder effective on and as of the date of such change
in the Base Rate. The above notwithstanding, Borrower may elect to and cause
all or a portion of the principal outstanding on this Note to bear interest at
a daily rate equal to one and one-half percent (1.5) in excess of the London
Interbank Offered Rate ("LIBOR") as announced by Bank from time to time
pursuant to the terms and conditions of that certain London Interbank Offered
Rate Borrowing Agreement between Borrower and Bank dated March 28, 1995.
Interest accruing prior to maturity shall be payable by Borrower to Bank
monthly, or as billed by Bank to Borrower, at Bank's principal place of
business, or at such other place as Bank may designate from time to time
hereafter. All unpaid interest at maturity shall be paid with the principal
amount of Borrower's Liabilities due hereunder.
 
  Upon the occurrence of an Event of Default, as hereinafter defined, interest
on the unpaid principal balance shall accrue at a rate equal to the then
existing Base Rate plus three percent (3%) per annum.
 
 
                                     E-11
<PAGE>
 
  Borrower agrees that in any action or proceeding instituted to collect or
enforce collection of this Note, the amount recorded on the books and records
of the Bank shall be prima facie evidence of the unpaid principal balance of
the Note; provided that the failure of the Bank to record any advance
hereunder shall not limit or otherwise affect the obligation of the Company to
repay the principal amount owing on this Note together with accrued interest
thereon.
 
  If any payment becomes due and payable on a Saturday, Sunday or legal
holiday under the laws of the State of Illinois, the due date of such payment
shall be extended to the next business day. If the date for any payment of
principal is thereby extended or is extended by operation of law or otherwise,
interest thereon shall be payable at the then applicable rate of interest for
such extended time.
 
  Borrower warrants and represents to Bank that Borrower shall use the
proceeds represented by this Note solely for the proper business purposes, and
consistently with all applicable laws and statutes.
 
  All of Bank's rights and remedies under this Note are cumulative and non-
exclusive. The acceptance by Bank of any partial payment made hereunder after
the time when any of Borrower's Liabilities become due and payable will not
establish a custom, or waive any rights of Bank to enforce prompt payment
thereof. Bank's failure to require strict performance by Borrower of any
provision of this Note shall not waive, affect or diminish any right of Bank
thereafter to demand strict compliance and performance therewith. Any waiver
of an Event of Default hereunder shall not suspend, waive or affect any other
Event of Default hereunder. Borrower and every endorser waive presentment,
demand and protest and notice of presentment, protest, default, non-payment,
maturity, release, compromise, settlement, extension or renewal of this Note,
and hereby ratify and confirm whatever Bank may do in this regard. Borrower
further waives and all notice or demand to which Bank might to entitled with
respect to this Note by virtue of any applicable statute or law (to the extent
permitted by law).
 
  Borrower agrees to pay, upon Bank's demand therefore, any and all reasonable
costs, fees and expenses (including attorneys' fees, costs and expenses)
incurred in enforcing any of Bank's rights hereunder, and to the extent not
paid the same shall become part of Borrower's Liabilities hereunder.
 
  If any provision of this Note or the application thereof to any party or
circumstance is held invalid or unenforceable, the remainder of this Note and
the application thereof to other parties or circumstances will not be affected
thereby, the provisions of this Note being severable in any such instance.
 
  This Note is submitted by Borrower to Bank at Bank's principal place of
business and shall be deemed to have been made there at. This Note shall be
governed and controlled by the laws of the State of Illinois as to
interpretation, validity, construction, affect, choice of law and in all other
respects.
 
  No modification, waiver, estoppel, amendment, discharge or change of this
Note or any related instrument shall be valid unless the same is in writing
and signed by the party against which the enforcement of such modification,
waiver, estoppel, amendment, discharge or change is sought.
 
  TO INDUCE BANK TO ACCEPT THIS NOTE, BORROWER IRREVOCABLY AGREES THAT,
SUBJECT TO BANK'S SOLE AND ABSOLUTE ELECTION, ALL ACTIONS OR PROCEEDINGS IN
ANY WAY, MANNER OR RESPECT, ARISING OUT OF OR FROM OR RELATED TO THIS NOTE
SHALL BE LITIGATED IN COURTS HAVING SITUS WITHIN THE CITY OF CHICAGO, STATE OF
ILLINOIS. BORROWER HEREBY CONSENTS TO THE JURISDICTION OF ANY LOCAL, STATE OR
FEDERAL COURT LOCATED WITHIN SMD CITY AND STATE AND WAIVES ANY OBJECTION IT
MAY HAVE BASED ON IMPROPER VENUE OR FORUM NON CONVENIENS TO THE CONDUCT OF ANY
PROCEEDING INSTITUTED HEREUNDER.

                                    PART I
 
ITEM 1. BUSINESS
 
  CORCOM, Inc. is an Illinois corporation incorporated in March, 1955. Except
as otherwise indicated by the context, references herein to "CORCOM" or the
"Company" mean CORCOM, Inc. and its subsidiaries. CORCOM's business consists
of the design, manufacture, and sale of radio frequency interference filters
to the commercial, facility, and military filter markets. The Company also
manufactures and sells a broad line of power entry devices that are used to
connect electronic equipment to an external power source.
 
 Products
 
  Radio frequency interference (RFI) filters are electronic components used to
protect electronic equipment from radio frequency interference conducted
through the AC power cord. They are also used to control the emission of the
RFI generated by electronic equipment so these emissions do not interfere with
other electronic devices. Customers purchase RFI filters for emission control
purposes to bring their equipment into compliance with government regulations
that limit the amount of radio frequency interference that can be emitted by
digital computing devices. The Company also manufactures a complete line of
Signal Sentry(c) products, filtered modular RJ jacks designed to solve RFI
problems on signal lines.
 
  CORCOM maintains a catalog of standard commercial filters that contains
approximately 500 designs, offering a variety of sizes, electrical
configurations, current ratings and environmental capabilities. These filters
consist of electronic circuits utilizing passive electrical components:
inductance coils, capacitors, and resistors. These are enclosed in a metal or
plastic case having terminals, lead wires, or an integral connector, for
attachment to associated equipment. Sales of commercial filters, including
Signal Sentry(c) products, accounted for approximately 72% of net sales in
1997, 75% in 1996, and 70% in 1995.
 
  CORCOM also manufactures and sells RFI filters for the military and facility
markets. Both product lines are similar to commercial filters in their basic
function and design. However, military filters are subject to extremely high
performance requirements as described by military specification. Facility
filters are larger versions of the Company's line of commercial filters and
are used to control RFI conducted through the main power line feeding secure
facilities. Together they represented 5% of 1997 sales, 4% of 1996 sales, and
5% of 1995 sales.
 
  The Company also distributes a line of power entry products that are used to
connect electronic equipment with a power source. These devices come in a
variety of configurations and may include an on-off switch, voltage selector,
fuse holder, and an IEC connector. Some power entry products also contain an
RFI filter. CORCOM's line of power entry products contains items of its own
design, plus some products obtained under a private label agreement. Sales of
power entry devices accounted for 23% of net sales in 1997, 21% in 1996, and
25% in 1995.
 
  In addition to filters and power entry products, the Company distributes a
variety of A/C power cords for use with filters and power entry products
having integral power connectors plus a series of line to line capacitors used
for RFI suppression.
 
  All of the Company's products are marketed under its federally registered
trademark, "CORCOM".
 
  CORCOM filters are designed to meet the requirements of one or more safety
and reliability specifications, such as those of Underwriters Laboratories
(UL), the Canadian Standards Association (CSA), the Verband Deutscher
Electrotechniker (VDE) in Germany, and the Schweizerischer Elektrotechnischer
Verein (SEV) in Switzerland.
 
  All CORCOM filters are designed and built to operate continuously for at
least five years when connected across a live A/C power line. CORCOM filters
must perform without interruption because in most cases they are energized
even when the equipment in which they are installed is switched off.
 
                                      F-2

 Markets
 
  CORCOM power line RFI filters are used as electronic pollution control
devices by manufacturers of digital electronic equipment all over the world.
In addition, many filters are used by field service organizations for
installation in sensitive equipment which was manufactured without an
effective filter. Power entry products are sold into the same markets and
through the same channels of distribution. Military filters are sold to
defense contractors and U.S. government agencies for use in sensitive
electronic devices. Facility filters are sold principally to contractors for
installation in screen room test facilities, computer installations, or other
locations containing sensitive electronic equipment.
 
  Over 4,000 customers in the United States and more than 100 customers in
other countries purchased filters and power entry products from CORCOM or its
distributors in 1997. No single customer accounted for more than 10% of sales
in 1997, 1996, or 1995.
 
 Distribution
 
  Sales of CORCOM products in the United States are obtained by 18 independent
sales representative firms which call on major original equipment
manufacturers (OEM's), government contractors, U.S. government agencies, and
independent electronic parts distributors. There are 28 United States
distributor firms which carry the Company's products; these distributors
service the smaller OEM's and the service organizations. Both representatives
and distributors handle other types of products, and some distributors carry
competing lines.
 
  Export sales are conducted through combination representative/distributor
organizations. Representative sales are on a commission basis with shipments
directly to OEM's. On a distributor basis, filters and power entry products
are imported and sold to customers within their countries.
 
  The Company has 35 international representative/distributors plus wholly-
owned subsidiaries in Germany and Mexico. This network sold into 24 countries
in 1997. Primary export markets include Canada, Germany, the United Kingdom,
France, Italy, Spain, Sweden, Japan, South Korea, Taiwan, and Hong Kong.
International catalogs are published in German and English. During 1997 the
Company closed its direct sales office in Hong Kong but continues to serve
this market through local distributors. Total international sales, which
include the sales from Corcom's German subsidiary, totaled $9,933,000 in 1997
(27.0% of net sales), $9,490,000 in 1996 (28.6% of net sales) and $7,688,000
in 1995 (25.1% of net sales). For further business information by geographic
area, reference is made to note 8 to the Consolidated Financial Statements.
 
  Export sales from the United States are invoiced in United States dollars
while sales of the Company's German subsidiary are invoiced in German
Deutschmarks. All international sales are subject to factors such as changes
in foreign exchange rates, protective tariffs, tax policy and export/import
controls.
 
  CORCOM supports the marketing of its products by wide distribution of its
catalogs, by advertising in technical publications, and via an informational
internet site on the worldwide web. Advertising and catalog costs for the
Company were approximately $289,000, $284,000, and $209,000 in 1997, 1996, and
1995, respectively.
 
 Backlog
 
  The Company's backlog of orders with firm delivery schedules was
approximately $8,260,000 on January 31, 1998, compared to $9,296,000 on
January 31, 1997. The backlog consists principally of special orders and
scheduled increments of volume contracts. Most catalog items are shipped from
inventory. Typical lead time for special orders is 12-14 weeks. Over 80% of
all orders are scheduled for delivery within 6 months. The Company does not
believe that its business is subject to seasonal variations.
 
 Competition
 
  Although industry statistics generally are not available, CORCOM believes
that in the United States it accounts for approximately 25% of commercial and
industrial power line interference filters, exclusive of
 
                                      F-3
<PAGE>
 
military applications. Competition principally includes Schaffner A.G. of
Switzerland; Delta of Taiwan; Aerovox, Inc.; Stanford Applied Engineering,
Inc.; as well as a number of lesser participants. CORCOM believes that its
sales volume is approximately equal to the aggregate volume of its three
principal United States competitors. In Europe the principal competitors are
Schaffner A.G., Siemens, Timonda and Eichoff. In the Far East CORCOM's
principal competitor is Delta. Many of the competitors are firms much larger
than CORCOM, with far greater financial resources, broader product lines and
larger marketing organizations.
 
  CORCOM believes that its position in the commercial and industrial power
line interference filter market results from a number of factors, including
the Company's concentration on this market sector, its emphasis on application
engineering to meet individual customer requirements, its reputation for high
product reliability and quality, its broad catalog line, and its ability to
provide standard items from inventory and/or local distributor stock. The
Company believes that these factors have to date enabled CORCOM products to
achieve high acceptance in the marketplace.
 
  Because the Company's products are an integral part of the digital
electronic equipment produced by its OEM customers, there will always be the
possibility of a customer electing to produce its own RFI filters and power
entry products rather than purchase the Company's products.
 
  CORCOM's major competitor in power entry products is Schaffner A.G. of
Zurich, Switzerland. The Company believes that the two companies comprise
approximately half the market for these devices in the United States, with
each company having approximately the same market share.
 
 Production, Testing, and Assembly
 
  CORCOM's products are composed of electrical components such as capacitors
and inductors and connectors which are wired into specific circuit
configurations, soldered, assembled into metal or plastic housings, and
tested. Materials and components generally are available from multiple
sources, and loss of a particular supplier would not be expected to have a
materially adverse effect on the Company's operations.
 
 Engineering
 
  The Engineering Department is divided into four sections--Applications,
Catalog, Support, and Manufacturing Engineering. Applications Engineering
provides assistance to key OEM accounts as well as customers within specific
geographic regions. Catalog Engineering develops new products based on input
from Marketing, and maintains and improves existing catalog products through
new technologies. Support Engineering consists of Safety Engineering, which
ensures compliance with safety regulations worldwide, and Test Engineering,
which develops and maintains all testing and inspection equipment.
Manufacturing Engineering verifies that the necessary equipment, tooling and
processes are in place, and updates manufacturing on new and developing
techniques and processes. The costs associated with the Engineering Department
were $1,333,000 in 1997. This compares to $1,220,000 in 1996 and $1,247,000 in
1995.
 
 ISO Registration
 
  CORCOM's manufacturing facilities were granted ISO 9001 registration in 1995
by Underwriters Laboratories. This registration validates a company's
management system to the internationally accepted ISO 9001 standard relative
to the design, manufacturing, and quality of the products it manufactures. ISO
registration is seen as a benefit to CORCOM's customers, as well as a vehicle
to promote a continuous improvement philosophy within the Company.
 
 Government Regulations
 
  The Federal Communications Commission (FCC) has adopted regulations to
reduce the interference potential of electronic equipment having circuitry
"that generates and uses timing signals or pulses at a rate in
 
                                      F-4
<PAGE>
 
excess of 10,000 pulses (cycles) per second and uses digital techniques." This
definition includes essentially all A/C powered computers and other digital
equipment. Although the FCC has exempted several specific types of devices,
compliance with these rules has been required for most types of A/C powered
digital equipment since October, 1983.
 
  CORCOM believes that in most cases compliance with the FCC requirements will
require the suppression of conducted RFI through the use of power line
interference filters, and these are now considered a standard component in
most A/C powered digital electronic equipment.
 
  Outside the United States, RFI is controlled by national and regional
regulation. In Europe, the European Union (EU) has established directives to
control RFI which, in most respects, take into account the recommendations of
the special committee on radio interference (CISPR) of the International
Electrotechnical Commission (IEC). As of January 1, 1996, all electrical or
electronic products under the scope of the EU directives intended for sale or
distribution in the EU countries must display the CE marking for proof of
compliance with the EU specifications. These specifications in many respects
are similar to the FCC rules. It is therefore possible for a manufacturer
using a CORCOM filter to produce equipment in such a manner that it complies
with both FCC and international interference control regulations as well as
domestic and foreign safety requirements.
 
 Patents
 
  The Company holds 12 patents. It may be possible for competitors of CORCOM
to copy aspects of its products even though the Company regards these as
proprietary. However, the Company believes that patent protection is of less
importance than the knowledge and experience of its management and personnel
and their ability to develop and market the Company's products. The Company
will apply for patents if and when it develops patentable processes or
products. The Company is not aware that the manufacture and sale of its
products, including those presently under development, require it to obtain
any licenses from others, although it may be necessary or desirable in the
future to obtain licenses for one or more of its future products.
 
 Employees
 
  On January 31, 1998, CORCOM had 672 full-time employees, of whom 576 were
engaged in production activities, 19 in product development and related
activities, 23 in sales and marketing, and 54 in general and administrative
capacities. The Company considers its employee relations to be excellent. The
Company has not experienced any work stoppage due to a labor dispute in over
31 years.
 
 Recent Development
 
  On March 10, 1998 Corcom, Inc. (the "Registrant") entered into an Agreement
and Plan of Merger by and among Communications Instruments, Inc., a North
Carolina corporation ("CII"), RF Acquisition Corp., an Illinois corporation
and wholly owned subsidiary of CII ("Merger Sub") and the Registrant (the
"Merger Agreement"). CII is owned by Code Hennessy & Simmons, LLC, a Chicago
based private investment firm, and CII management. Pursuant to the Merger
Agreement, (a) CII will acquire all of the Registrant's issued and outstanding
shares of common stock for $13.00 per share in cash, or approximately $51.2
million, and (b) Merger Sub will merge with and into Registrant (the
"Merger"), with Registrant being the surviving corporation in the Merger.
 
  The closing of the Merger is subject to the satisfaction of certain
conditions, including, among other matters, approval by the holders of two-
thirds of the issued and outstanding shares of common stock of the Registrant,
certain regulatory approvals and receipt by CII of debt financing necessary to
consummate the Merger, a commitment for which has been provided by Bank of
America National Trust and Savings Association. This financing is subject to
certain conditions, including the execution of a definitive credit agreement
satisfactory to Bank of America. A copy of the Merger Agreement is attached as
Exhibit 2.1 to the registrant's Current Report on Form 8-K (date of report
March 10, 1998) and is hereby incorporated by reference.
 
                                      F-5
<PAGE>
 
  CII also entered into an agreement with Werner E. Neuman, the President of
the Registrant, and James A. Steinback, a Director of the Registrant, whereby
such individuals agreed to vote in favor of the Merger. These two individuals
hold approximately 31% of the shares outstanding. A copy of this voting
agreement is attached as Exhibit 99.1 to the aforesaid Form 8-K and is hereby
incorporated by reference.
 
  A copy of the press release of the Registrant, dated March 11, 1998, is
attached as Exhibit 99.2 to the aforesaid Form 8-K and is hereby incorporated
by reference.
 
ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS.
 
  CORCOM's net sales for 1997 were $36,788,000, an increase of 10.9% from the
$33,166,000 reported for the previous year. The bulk of the increase came in
the form of a volume increase in the Company's North American commercial
filter business, the result of an increase in the overall electronics market.
Volume increases represented approximately $3,258,000 of the total increase of
$3,622,000. There were no appreciable price changes year to year. Between 1995
and 1996, sales increased 8.2%. Most of this increase came as a result of
volume increases in the Company's North American and European commercial
filter businesses. The increase in North America was the result of an increase
in the overall electronics market. The increase in Europe was principally
attributable to more stringent European RFI/EMI testing regulations which went
into effect January 1, 1996. There were no appreciable price changes in this
period either.
 
  The Company's backlog of orders with firm delivery schedules was $8,260,000
as of January 31, 1998, compared to $9,296,000 as of January 31, 1997 and
$10,346,000 on January 31, 1996. There has been a reduction in the last two
years of very long lead time orders by certain of the Company's customers;
however the value of orders deliverable in the upcoming 13 week period has
remained relatively constant over the last two years.
 
  In 1997 the Company's gross margins improved to 39.1% of sales from the
37.9% reported in 1996. This was primarily the result of cost reductions in
certain raw materials used by the Company, coupled with the leveraging impact
of higher production levels on the Company's fixed production-related costs.
The period 1995 to 1996 also showed an improvement in gross margins from 37.1%
in 1995 to 37.9% in 1996. This improvement was due to a shift in mix to more
profitable European sales partially offset by an increase in the peso-based
costs at the Company's Mexican production facility as a result of the
inflation in that currency during 1996. Since a portion of the Company's costs
are Mexican peso- based, should the value of that currency increase relative
to the dollar, or if inflation in Mexico escalates, the Company's
manufacturing costs could rise.
 
  Engineering expenses in 1997, at $1,333,000, were about 9.3% higher than the
$1,220,000 incurred in 1996, the result of resources added to this area in
1997 to keep up with rising demand. In 1996, engineering expenses were
approximately the same as they were in 1995. As a percent of revenue,
engineering expenses remained about the same in 1997, at 3.6% of sales, as
they were in 1996.
 
  Selling, administrative and other expenses were $545,000, or 7%, higher in
1997 than in 1996, the majority of which was due to higher commission and
sales expenses on the higher 1997 revenue and higher incentive compensation
costs on higher 1997 pretax income. Sales, administrative and other expenses
increased $704,000, or 10%, from 1995 to 1996. The major components of this
increase were higher sales commission and sales expenses on the higher levels
of sales in 1996.
 
  Interest expense was $10,000 in 1997 as compared with $16,000 and $71,000
for 1996 and 1995 respectively. Interest expense for 1997 and 1996 represents
the interest portion of lease payments on certain equipment leases only.
Interest expense for 1995 includes not only the interest portion of the
Company's lease payments, but interest expense on cash borrowings against the
Company's line of credit for a portion of that year. There have been no cash
borrowings since 1995.
 
  The Company recorded interest income from its cash and investments of
$306,000 in 1997. This was $172,000 higher than in 1996 as a result of the
increase in the Company's cash balances in this period. Interest income in
1996 was $127,000 higher than 1995, also the result of an increase in the
Company's level of cash.
 
                                      F-6
<PAGE>
 
  The Company's pre-tax earnings for 1997 were $5,013,000. This compares to
pre-tax earnings of $3,683,000 and $2,967,000 in 1996 and 1995 respectively.
The primary reasons for the improvement are discussed above.
 
  The Company recorded a provision for income tax expense of $2,010,000 in
1997. This represents approximately 40% of pretax earnings. In 1996, the
Company recorded a net income tax benefit of $1,789,000. The principal
component of this benefit was a $2,000,000 reversal of part of the valuation
allowance which existed as of December 31, 1995 as related to existing tax net
operating loss (NOL) carryforwards. Since it became apparent in 1996 that
there were no longer any uncertainties surrounding the ultimate utilization of
these NOL's, the valuation allowances against this deferred asset were
removed, resulting in the negative income tax expense in the period. In 1995,
the Company had recorded a minimal provision for income tax expense of
$181,000, or 6.1% of pretax earnings.
 
The Company's net income after tax in 1997 was $3,003,000 ($.76 per share,
diluted). This compares to net earnings of $5,472,000 ($.1.38 per share,
diluted) and $2,786,000 ($.72 per share, diluted) in 1996 and 1995
respectively. The decrease from 1996 to 1997 is due to the effect of the 1996
tax credit described in the paragraph above. If both 1995 and 1996 earnings
were taxed at the full statutory 40% rate, proforma diluted earnings per share
for these two periods would have been $.46 and $.56, respectively. Weighted
average shares outstanding (diluted) for 1997 were 3,952,000, a decrease of
5,000 shares from the 3,957,000 weighted average shares outstanding reported
for 1996. The decrease was the net effect of the issuance of the 48,000 shares
on exercise of stock options by certain key employees in 1996, the dilutive
effect of existing unexercised stock options, and the purchase by the Company
throughout 1997 of 98,300 shares for the treasury. Weighted average shares
outstanding in 1996 were 3,957,000, an increase of 90,000 shares from the
3,867,000 reported in 1995. This increase was the joint result of the issuance
of 75,000 shares on exercise of stock options by certain key employees in
1996, and the dilutive effect of existing unexercised stock options.
 
 Liquidity and Capital Resources
 
  As of December 31, 1997, the Company had cash reserves on hand of $8,232,000
as compared with $4,789,000 cash on hand as of December 31, 1996. As detailed
in the Consolidated Statements of Cash Flow presented on page F-6 of this Form
10-K, this increase in cash was the net result of cash provided by operating
activities (principally net income plus depreciation) of $5,558,000, less cash
invested in property, plant, and equipment of $1,288,000, less cash used in
financing activities (principally the repurchase of Corcom common shares for
treasury) of $827,000. This cash is invested in money-market, Eurodollar, and
other conservative and liquid vehicles. In addition to current cash reserves,
the Company's loan agreement with American National Bank and Trust Company of
Chicago was renewed on December 31, 1996 and is now in effect until April 30,
1998. This agreement is an unsecured line of credit with maximum borrowings of
$4,000,000, or 80% of eligible accounts receivable, whichever is less.
Interest on this loan is the Company's choice of either LIBOR plus 150 basis
points, or the Bank's prime rate. There were no borrowings against this
agreement as of either December 31, 1997 or 1996.
 
  As of December 31, 1997, the Company had foreign income tax carryforwards of
$1,894,000, principally in Hong Kong, Mexico and the West Indies.
Approximately $1,485,000 of the foreign NOL carryforwards have no expiration
date. The company had no domestic income tax NOL carryforwards remaining as of
December 31, 1997.
 
  Management feels that existing cash balances and the existing bank line of
credit will be sufficient to support its cash needs through 1998. Except for a
significant change in general economic conditions affecting the Company, its
suppliers, and/or its customers, the Company is not aware of any trends which
would be reasonably likely to result in the Company's liquidity increasing
(other than as a result of profitable operations) or decreasing in a material
manner.
 
  In 1997, the Company began converting its computer systems to be year 2000
compliant. Most of the Company's business software consists of externally
written, generic "packages" which have already been
 
                                      F-7

upgraded to be year 2000 compliant by their publishers. These upgraded
versions have been made available to the Company as part of its normal
software licensing and/or maintenance agreements. In certain cases,
installation of the upgraded systems may require additional purchased hardware
or software which would be recorded as assets and amortized. In addition to
its main purchased business software, but to a much lesser extent, the Company
also has some internally developed systems and subsystems which are in the
process of being made year 2000 compliant. The Company does not believe it
will encounter any material problems with this conversion. Management does not
feel that the cost of this conversion will be material.
