  Dear Shareholder:

       We invite you to attend a Special Meeting (the "Infocore Meeting") of
  Shareholders to be held at 661 Moore Road, King of Prussia, Pennsylvania 19406
  on Monday, April 21, 1997, at 10:00 a.m., local time.

       In a recent mailing, I appraised you of our merger discussions with 
  Conestoga Enterprises, Inc. with whom we have worked as a joint venture
  partner in the successful effort to acquire 4 PCS licenses in the recent FCC
  auctions. At this writing, we have completed a number of important steps in
  the merger process including the completion of the SEC review process.

       At the Infocore Meeting, shareholders will be asked to consider and vote
  upon approval of the Agreement and Plan of Merger dated as of March 14, 1997
  (the "Merger Agreement") among Infocore, Conestoga Enterprises, Inc. ("CEI")
  and CI Merger Corporation, a wholly owned subsidiary of CEI ("Merger Sub").
  Pursuant to the Merger Agreement, Infocore would be merged (the "Merger") with
  and into Merger Sub, with Merger Sub being the surviving corporation.  In
  connection with the Merger and as more fully described in the accompanying
  Joint Proxy Statement/Prospectus, shares of Infocore common stock, par value
  $.02 per share (the "Infocore Common Shares"), outstanding as of the effective
  time of the Merger will be converted into and become a right to receive shares
  of CEI common stock, par value $5.00 per share ("CEI Common Shares").  All
  outstanding Infocore Common Shares shall in the aggregate be converted into
  200,000 CEI Common Shares.

       Your attention is directed to the attached Proxy Statement/Prospectus
  which contains a more complete description of the terms of the Merger and
  provides detailed financial, business and other information concerning
  Infocore and CEI.

       After careful consideration of the terms of the Merger Agreement, the
  board of directors of Infocore has determined that the Merger is in the best
  interests of Infocore and its shareholders.  ACCORDINGLY, YOUR BOARD OF
  DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE FOR APPROVAL OF THE MERGER
  AGREEMENT.

       It is very important that your shares be represented at the Infocore
  Meeting, whether or not you plan to attend in person.  The affirmative vote of
  a majority of the Infocore Common Shares present and entitled to vote at the
  Infocore Meeting is required to approve the Merger Agreement.  We urge you to
  execute, date and return the enclosed proxy card in the enclosed postage-paid
  envelope as soon as possible to assure that your shares will be voted at the
  meeting.  On behalf of the Board of Directors, we thank you for your support
  and urge you to vote "FOR" approval of the Merger Agreement.

       Infocore shareholders will be entitled to exercise statutory dissenters'
  rights with respect to the Merger.  To exercise such rights, Infocore
  shareholders must provide written notice of their intention to dissent to
  Infocore prior to the vote at the Infocore Meeting.  Returned proxies which do
  not contain voting instructions will be voted "FOR" approval of the Merger.

                                      Sincerely,


                                      Harrison H. Clement, Jr.
                                      President and Chief Executive Officer

                        SPECIAL MEETING OF SHAREHOLDERS
                                 APRIL 21, 1997

                          CONESTOGA ENTERPRISES, INC.
                                PROSPECTUS FOR
                      200,000 SHARES OF CEI COMMON STOCK
                           PAR VALUE $5.00 PER SHARE

       This Proxy Statement/Prospectus is being furnished to holders of common
  stock, $.02 par value ("Infocore Common Shares"), of Infocore, Inc., a
  Pennsylvania corporation ("Infocore"), in connection with the solicitation of
  proxies by Infocore's Board of Directors (the "Infocore Board") for use at a
  Special Meeting of Shareholders (the "Infocore Meeting") to be held at 661
  Moore Road, King of Prussia, Pennsylvania 19406, on Monday, April 21, 1997 at
  10:00 a.m., local time.  At the Infocore Meeting, shareholders of Infocore
  will be asked to consider and vote upon (i) a proposal to approve the
  Agreement and Plan of Merger dated as of March 14, 1997 (the "Merger
  Agreement") among Infocore, Conestoga Enterprises, Inc., a Pennsylvania
  corporation ("CEI") and CI Merger Corporation, a wholly owned subsidiary of
  CEI ("Merger Sub"), and (ii) such other business as may properly come before
  the Infocore Meeting or any adjournment thereof.

       Pursuant to the Merger Agreement, Infocore would be merged (the "Merger")
  with and into Merger Sub, with Merger Sub being the surviving corporation.
  All outstanding Infocore Common Shares shall in the aggregate be converted
  into 200,000 CEI Common Shares.

       This Proxy Statement/Prospectus also constitutes a prospectus of CEI
  filed as part of a registration statement filed with the Securities and
  Exchange Commission (the "Commission") relating to 200,000 CEI Common Shares
  issuable pursuant to the Merger Agreement.  All information contained in this
  Proxy Statement/Prospectus with respect to CEI and its subsidiaries has been
  supplied by CEI, and all information with respect to Infocore has been
  supplied by Infocore.

       Shareholders should carefully consider the information under "RISK
  FACTORS" beginning on page 14 in determining how to vote with respect to the
  matters to be considered at the Infocore Meeting and, with respect to Infocore
  shareholders, whether to exercise dissenters' rights.

       This Proxy Statement/Prospectus does not cover any resales of the CEI
  Common Shares issuable in the Merger by any shareholders deemed to be
  affiliates of Infocore or CEI.  No person is authorized to make use of this
  Proxy Statement/Prospectus in connection with any such resale.

       THE CEI COMMON SHARES ISSUABLE IN THE MERGER HAVE NOT BEEN APPROVED OR
  DISAPPROVED BY THE SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES
  COMMISSION, NOR HAS THE SECURITIES AND EXCHANGE COMMISSION OR ANY STATE
  SECURITIES COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROXY
  STATEMENT/PROSPECTUS.  ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL
  OFFENSE.

       This Proxy Statement/Prospectus and the accompanying proxy cards and
  notices of special meeting are first being mailed to shareholders of Infocore
  on or about April 9, 1997.

  The date of this Proxy Statement/Prospectus is April 9, 1997

 other than those contained in this Proxy Statement/Prospectus and, if given or

 not constitute an offer to sell, or a solicitation of an offer to buy, any
 security other than the securities covered by this Proxy Statement/Prospectus,
 or the solicitation of a proxy to or from any person in any jurisdiction where
 it is unlawful to make such offer or solicitation of an offer or proxy
 solicitation. Neither the delivery of this Proxy Statement/Prospectus nor any
 distribution of securities made hereunder shall, under any circumstances,
 create any implication that there has been no change in the information about
 CEI or Infocore contained in this Proxy Statement/Prospectus since the date
 hereof.

                                    SUMMARY

       This summary does not purport to be complete and is qualified in its
     entirety by the more detailed information appearing elsewhere or
     incorporated by reference in this Proxy Statement/Prospectus and the
     Appendices hereto.  Shareholders are urged to read this entire Proxy
     Statement/Prospectus, including the Appendices hereto.  Certain terms used
     in this summary and elsewhere in this Proxy Statement/Prospectus are used
     as defined in this summary or elsewhere in this Proxy Statement/Prospectus.


                                 The Companies

     CEI

       Conestoga Enterprises, Inc. ("CEI"), incorporated in the Commonwealth of
     Pennsylvania in 1989, is a holding company with wholly owned subsidiaries
     engaged in various aspects of the telecommunications business.

       CEI's principal subsidiaries are Conestoga Telephone and Telegraph
     Company ("CTT") and Buffalo Valley Telephone Company ("BVT"), both of which
     are local exchange carriers ("LEC").  CTT, incorporated in 1902, furnishes
     communication services, mainly local and toll telephone service, to an area
     of approximately 300 square miles, including parts of Berks, Chester,
     Lancaster and Montgomery Counties in Pennsylvania.  CTT provides service to
     approximately 48,150 access lines.  The population of CTT's service area is
     estimated to be 120,400.  BVT was originally founded in 1904 and provides
     local telephone service to Union and Northumberland Counties in Central
     Pennsylvania.  BVT provides service to approximately 19,100 telephone
     access lines.  The population of BVT service area is estimated to be
     32,000.

       Other subsidiaries include Northern Communications, Inc. ("NCI"), which
     is engaged in the resale of long distance service as a non-regulated
     business, Conestoga Mobile Systems, Inc. ("CMS"), which is engaged in the
     provision of paging services, and Conestoga Investment Corporation ("CIC"),
     which is an investment company incorporated in the State of Delaware to
     hold certain CEI investments.  CMS provides service to approximately 4,700
     paging access lines.

       CEI owns interests in two joint ventures which provide cellular telephone
     services in the Reading,  Harrisburg, Lancaster and York Metropolitan
     Areas.  In 1995, CTT acquired an 11.85% interest in a partnership that
     provides Internet and similar computer services in Pennsylvania east of the
     Susquehanna River.

       CEI owns a 60% interest in Conestoga Wireless Company ("CWC"), which was
     formed by CEI and Infocore in March 1995 to bid in the auctions by the
     Federal Communications Commission for bandwidth to provide Personal
     Communication Services ("PCS"), a wireless telecommunications technology.
     CWC was successful in bidding for radio spectrum "D" bandwidth in the
     Reading, Pottsville and Williamsport, Pennsylvania basic trading areas and
     for "F" bandwidth in the Sunbury basic trading area.  These territories
     cover nine (9) counties in Pennsylvania with a population of 840,000.

       CEI's executive offices are located at 202 East First Street, Birdsboro,
     Pennsylvania 19508, and its telephone number is (610) 582-8711.

     Infocore, Inc.

       Infocore, Inc., a Pennsylvania corporation ("Infocore"),  is a
     diversified telecommunications services company founded in 1981, which
     designs, installs and maintains telephone and computer systems and resells
     local exchange and toll services.  Infocore Wireless, Inc., a wholly owned
     subsidiary, owns a 40% interest in CWC.

       Infocore's offices are located at 661 Moore Road, King of Prussia,
     Pennsylvania 19406, and its telephone number is (610) 337-9611.

                             The Infocore Meeting

General

          The special meeting of the shareholders of Infocore will be held
on Monday, April 21, 1997, at 10:00 a.m., local time, at 661 Moore Road,
King of Prussia, Pennsylvania 19406 (the "Infocore Meeting").

Matters to be Considered at the Infocore Meeting

          At the Infocore Meeting, holders of common stock, par value $.02
per share, of Infocore ("Infocore Common Shares"), will be asked to
consider and vote upon (i) a proposal to approve the Agreement and Plan of
Merger dated as of March 14, 1997 (the "Merger Agreement") among Infocore,
CEI and CI Merger Corporation, a wholly owned subsidiary of CEI ("Merger
Sub"), and (ii) such other business as may properly come before the
Infocore Meeting or any adjournment thereof.  See "THE INFOCORE MEETING-- 
Matters to be Considered at the Infocore Meeting."

Record Date; Shares Outstanding; Quorum; Vote Required

          Only holders of record of Infocore Common Shares at the close of
business on April 7, 1997 (the "Infocore Record Date"), will be entitled to
notice of, and to vote at, the Infocore Meeting. Each Infocore Common Share
outstanding on the Infocore Record Date entitles its holder, as of that date, to
one vote. As of the Infocore Record Date, there were 5,778,956 Infocore Common
Shares outstanding and entitled to be voted at the meeting, held by
approximately 142 shareholders of record, and outstanding options to acquire an
additional 921,731 Inforce Common Shares. The presence in person or by proxy of
the holders of a majority of the Infocore Common Shares entitled to vote at the
Infocore Meeting shall constitute a quorum at the Infocore Meeting. See "THE
INFOCORE MEETING--Infocore Record Date; Shares Outstanding; Quorum, Vote
Required." Pursuant to the applicable provisions of the Pennsylvania Business
Corporation Law ("PBCL") and Infocore's bylaws (the "Infocore Bylaws"), the
affirmative vote of a majority of the Infocore Common Shares present and
entitled to vote at the Infocore Meeting is required to approve the Merger
Agreement. See "THE INFOCORE MEETING--Vote Required."

          As of the Infocore Record Date, directors and executive officers of
Infocore beneficially owned approximately 1,228,004 Infocore Common Shares or
approximately 21.24% of the Infocore Common Shares entitled to vote at the
Infocore Meeting, and such persons also hold options to acquire an additional
719,000 Infocore Common Shares. See "BUSINESS OF INFOCORE--Security Ownership of
Certain Beneficial Owners and Management of Infocore." The directors and
executive officers of Infocore have indicated that they intend to vote all of
such shares in favor of approval of the Merger Agreement. See "THE INFOCORE
MEETING--Vote Required."


                                  The Merger

Terms of the Merger

          Pursuant to the Merger Agreement, Infocore would be merged (the
"Merger") with and into Merger Sub, with Merger Sub being the surviving
corporation. All outstanding Infocore Common Shares (including Infocore Common
Shares acquired pursuant to the exercise of outstanding options between the
Infocore Record Date and the Effective Time) shall in the aggregate be converted
into 200,000 CEI Common Shares (the "Merger Consideration"), less fractional
shares and Dissenters' shares.

          No fractional CEI Common Shares will be issued.  Holders of
Infocore Common Shares who would otherwise be entitled to receive a
fractional share of CEI Common Stock instead will receive a cash payment
determined by multiplying the fractional interest to which such holder
would otherwise be entitled by the Market Value of a CEI Common Share.  See
"THE MERGER--Terms of the Merger."

INFOCORE SHAREHOLDERS SHOULD NOT FORWARD STOCK CERTIFICATES FOR INFOCORE
COMMON SHARES TO CEI OR INFOCORE UNTIL THEY HAVE RECEIVED A RETURN

INSTRUCTION FORM. INFOCORE SHAREHOLDERS SHOULD NOT RETURN STOCK CERTIFICATES
WITH THE ENCLOSED PROXY CARD.

Recommendation of the Infocore Board of Directors

        The consideration to be received by holders of Infocore Common Shares in
the Merger was negotiated by the Infocore Board in light of various factors,
including Infocore's and CEI's recent operating results, current financial
condition and perceived future prospects. THE BOARD OF DIRECTORS OF INFOCORE
BELIEVES THAT THE MERGER IS IN THE BEST INTERESTS OF INFOCORE SHAREHOLDERS, HAS
UNANIMOUSLY APPROVED THE MERGER AGREEMENT AND RECOMMENDS THAT INFOCORE'S
SHAREHOLDERS VOTE "FOR" APPROVAL OF THE MERGER AGREEMENT. See "THE MERGER--
Infocore's Reasons for the Merger; Recommendation of the Infocore Board of
Directors."

Opinion of CEI Financial Advisor

        JSI Financial Services ("JSI") rendered its opinion to the Board of
Directors of CEI (the "CEI Board") on March 14, 1997 to the effect that the
consideration to be paid by CEI to holders of Infocore Common Shares in the
Merger is fair to the CEI shareholders from a financial point of view. This
opinion, which is attached to this Proxy Statement/Prospectus as Appendix B,
should be read in its entirety with respect to the assumptions made and other
matters considered by JSI in rendering such opinion. CEI has agreed to pay JSI
$15,000 for acting as its financial advisor in connection with the Merger.
See "THE MERGER--Opinion of CEI Financial Advisor."

Conditions to the Merger

        Consummation of the Merger is subject to various conditions, including
the approval of the Merger Agreement by the requisite vote of the shareholders
of Infocore and the satisfaction of various conditions set forth in the
Agreement and Plan of Merger dated as of March 14, 1997, among CEI, Merger Sub
and Infocore ("Merger Agreement"), a copy of which is attached hereto as
Appendix A. Among other conditions, the Merger is conditioned upon the exercise
of dissenters' rights by holders of not more than 10% of the Infocore Common
Stock. See "THE MERGER--Terms of the Merger--Conditions to the Merger". CEI's
obligations are also conditioned upon Harrison H. Clement, Jr., President and
Chief Executive Officer of Infocore, and Henry M. Stringer, Senior Vice
President of Infocore, entering into employment agreements with Merger Sub
providing for their continued employment after the Merger.

Certain Covenants

        Upon consummation of the Merger, the separate existence of Infocore and
its board of directors will terminate, but the directors and officers of CEI and
Merger Sub will continue in office. See "THE MERGER--Terms of the Merger."


        Infocore has agreed that, except as described below, it will not
initiate discussions or negotiations relating to a transaction involving a
merger, consolidation, sale or similar transaction involving a significant
portion of the stock or assets of Infocore (an "Acquisition Transaction").
Infocore, however, is permitted to disclose information to, and to engage in
discussions and negotiations with, a person who makes a bona fide offer to
engage in such an Acquisition Transaction on terms which are more favorable to
the Infocore shareholders than the Merger, and who can reasonably be expected to
consummate such an Acquisition Transaction on the terms that have been proposed,
and which disclosure, discussions and negotiations, in the judgment of Infocore,
shall be required by reason of the fiduciary obligations of the Infocore Board.
See "THE MERGER--Terms of the Merger."

- --------------------------------------------------------------------------------

     Effective Time

        Once the conditions to the Merger have been satisfied, the Merger will
become effective upon the filing and acceptance of articles of merger by the
Corporation Bureau of the Commonwealth of Pennsylvania (the "Effective Time").
See "THE MERGER--Terms of the Merger; Effective Time."

Termination; Waiver; Amendment

        The Merger Agreement may be terminated at any time before the Closing
Date in a number of circumstances, including (i) by mutual consent of the
parties, (ii) by either party if the Effective Time shall not have occurred on
or before November 1, 1997 (except under certain circumstances), and (iii) by
either party upon a material breach of any representation, warranty, covenant or
agreement by the other party.

        In addition, if requested by the Infocore Board pursuant to the
fiduciary obligations of Infocore's directors, Infocore may terminate the Merger
Agreement (subject to its obligations to pay the termination fee described
below) in order to accept an offer for an Acquisition Transaction other than the
Merger which the Infocore Board concludes is more favorable to the Infocore
shareholders than the Merger. See "THE MERGER--Terms of the Merger--Termination;
Waiver; Amendment."

        Prior to the Effective Time, any provision of the Merger Agreement may
be waived or amended under certain circumstances, as set forth in the Merger
Agreement. See "THE MERGER--Terms of the Merger--Termination; Waiver;
Amendment."

Fees and Expenses

        Except as described below, whether or not the Merger is consummated, all
costs and expenses incurred in connection with the Merger Agreement and the
transactions contemplated thereby will be paid by the party incurring such
costs.

        In the following circumstances, Infocore has agreed to pay CEI a break-
up fee in the amount of $100,000: (1) the Merger Agreement being terminated by
CEI due to (i) Infocore's representations and warranties contained in the Merger
Agreement not being true and correct in all material respects when made or as of
the Closing Date; or (ii) Infocore's failure to perform in all material respects
all obligations and comply in all material respects with all agreements,
undertakings, covenants and conditions required by the Merger Agreement to be
performed or complied with by it at or prior to the Effective Date; (2) the
Merger Agreement being terminated by Infocore in order to enter into an
Acquisition Transaction; or (3) the Merger Agreement being terminated by either
CEI or Infocore as a result of the failure to obtain Infocore shareholder
approval of the Merger Agreement and the transactions contemplated thereby.

        In the following circumstance, CEI has agreed to pay Infocore a break-up
fee in the amount of $100,000: the Merger Agreement being terminated by Infocore
due to (i) CEI's or Merger Sub's representations and warranties contained in the
Merger Agreement not being true and correct in all material respects when made
or as of the Closing Date; or (ii) the failure of CEI or Merger Sub to perform
in all material respects all obligations and comply in all material respects
with all agreements, undertakings, covenants and conditions required by the
Merger Agreement to be performed or complied with by CEI at or prior to the
Effective Date.

Dissenters' Rights

        Pursuant to the PBCL, the holders of Infocore Common Shares will have
the right to dissent from approval of the Merger, and to demand and receive the
"fair value" of their Infocore Common Shares. In order to assert such
dissenters' rights, an Infocore shareholder must (i) file a written notice of
intention to dissent with Infocore prior to the shareholder vote at the Infocore
Meeting, (ii) refrain from voting in favor of the Merger, (iii) file a written

- --------------------------------------------------------------------------------

                                      -9-

- --------------------------------------------------------------------------------

demand for payment and deposit the certificates representing his or her shares
in accordance with the terms of the notice to demand payment that will be sent
by Infocore, and (iv) comply with certain other statutory procedures set forth
in the PBCL. Proxies which are returned but which do not contain voting
instructions will be voted in favor of the Merger Agreement, which will result
in a forfeiture of dissenters' rights with respect to the Merger. A copy of the
applicable sections of the PBCL are attached to this Joint Proxy
Statement/Prospectus as Appendix C. Any deviation from the procedures set forth
in such statutory provisions may result in the forfeiture of dissenters' rights
with respect to the Merger. Accordingly, shareholders wishing to assert
dissenters' rights are urged to read carefully "THE MERGER--Dissenters' Rights"
and Appendix C to this Proxy Statement/Prospectus.

        CEI shareholders are not entitled to dissenters' rights in this
transaction.

Certain Federal Income Tax Consequences

        It is intended that the Merger will be treated for federal income tax
purposes as a reorganization within the meaning of Section 368(a) of the
Internal Revenue Code of 1986, as amended (the "Code"), and that, accordingly,
for federal income tax purposes: (i) Infocore, Merger Sub and CEI will each be
a "party to a reorganization" within the meaning of Section 368(b) of the Code,
(ii) no gain or loss will be recognized by Infocore by reason of the Merger,
(iii) except for any cash received in lieu of any fractional shares, no gain or
loss will be recognized by holders of Infocore Common Shares who, pursuant to
the Merger, receive solely CEI Common Shares in exchange for their Infocore
Common Shares, (iv) the basis of the CEI Common Shares to be received by an
Infocore shareholder will generally be the same as the basis of the Infocore
Common Shares surrendered in exchange therefor, less any basis attributable to
any fractional shares for which cash is received, and (v) the holding period of
the CEI Common Shares to be received by a shareholder of Infocore will include
the period during which the Infocore Common Shares surrendered in exchange
therefor were held, provided that the Infocore Common Shares surrendered were
held as a capital asset as of the Effective Time.

        Infocore's obligation to consummate the Merger is conditioned upon
receipt of an opinion of Saul, Ewing, Remick & Saul, tax counsel to Infocore,
substantially to the effect that the federal income tax consequences of the
Merger are as summarized above. Such an opinion of Saul, Ewing, Remick & Saul is
attached to this Proxy Statement/Prospectus as Appendix D. See "THE MERGER--
Certain Federal Income Tax Consequences."

        EACH INFOCORE SHAREHOLDER IS ENCOURAGED TO CONSULT HIS OR HER OWN TAX
ADVISOR AS TO PARTICULAR FACTS AND CIRCUMSTANCES WHICH MAY BE UNIQUE TO SUCH
SHAREHOLDER AND NOT COMMON TO INFOCORE SHAREHOLDERS AS A WHOLE AND ALSO AS TO
ANY ESTATE, GIFT, STATE, LOCAL OR FOREIGN TAX CONSEQUENCES ARISING OUT OF THE
MERGER AND/OR ANY SALE THEREAFTER OF CEI COMMON SHARES RECEIVED IN THE MERGER.

Accounting Treatment

        The Merger will be accounted for as a purchase of Infocore by CEI for
accounting and financial reporting purposes. See "THE MERGER--Accounting
Treatment."

Interest of Certain Persons in the Merger

        Certain directors and officers of Infocore have interests in the Merger
that are in addition to their interests as shareholders of Infocore generally.
These include the employment agreements between Harrison H. Clement, Jr.,
President and Chief Executive Officer of Infocore, and Henry M. Stringer, Senior
Vice President of Infocore, and Merger Sub upon which the Merger is conditioned.
See "THE MERGER--Terms of the Merger--Employment Contracts" and "THE MERGER--
Interest of Certain Persons in the Merger."

Comparison of Shareholder Rights

        Upon the exchange of shares in the Merger, holders of Infocore Common
Shares will become holders of CEI Common Shares. The rights of shareholders of
CEI are governed by the PBCL and by the CEI Articles and the bylaws of CEI (the
"CEI Bylaws"). The rights of common shareholders of CEI differ from the rights
of holders of Infocore Common Shares with respect to certain matters. For a
description of these differences, see "COMPARISON OF SHAREHOLDER RIGHTS."


                      Selected Historical Financial Data

        The following tables present selected historical financial data for CEI
and Infocore. The selected financial data set forth below for CEI for each of
the years in the five-year period ended December 31, 1996 and for Infocore for
each of the years in the three-year period ended December 31, 1996, are derived
from the financial statements of CEI and Infocore, respectively. The historical
financial information is not necessarily indicative of future operations or the
actual results that would have occurred had the Merger been consummated at the
beginning of the periods presented and should not be construed as representative
of future operations. Information regarding CEI and Infocore has been provided
by CEI and Infocore, respectively.

                                 RISK FACTORS

        The consideration to be received by holders of Infocore Common Shares
pursuant to the Merger consists of CEI Common Shares. In addition to the other
information contained in this Proxy Statement/Prospectus, holders of Infocore
Common Shares should consider carefully the following risk factors relating to
CEI and the CEI Common Shares before deciding how to vote with respect to the
Merger:

Competitive Industry

        CEI engages in various aspects of the telecommunications industry which
are becoming increasingly competitive. As a result of technological and
regulatory developments, CEI faces the risk of new or increased competition in
virtually all businesses in which it engages. It is not possible to predict the
future effect of these developments on the telecommunications industry in
general or on CEI in particular.

        In recent years, the telecommunications industry has been influenced by
rapid technological change in areas such as transmission capacity, switching
equipment, digital systems, fiber-optic cable, FAX, mobile and wireless
communications technologies, computer hardware and software, computer networking
and the Internet. The technological developments have resulted in an increase in
demand for telecommunications services, and also have, or soon will, make
possible the offering of a wide range of new, interactive, broadband
telecommunications services, including interactive video. These changes create
the opportunity for existing and new services to be delivered in a number of
different ways by a variety of different providers.

        The telecommunications industry has also been marked by an increasing
trend toward deregulation and increased competition. In recent years,
competitive access providers ("CAPs") and system bypass offered by long distance
(interexchange or "IXC") carriers, have emerged to offer alternative access for
the origination and termination of long distance calls than the local loop of
the local exchange carriers ("LECs"). These alternative access providers
represent a competitive inroad into a significant source of LEC revenue --
network access charges.

        In addition, the recently enacted Telecommunications Act of 1996 (the
"Act"), among other things, will open the local telephone markets of LECs to new
competitors, such as AT&T, MCI, Sprint, cable television providers and other
LECs, many of which have substantially greater technical, financial, marketing
and personnel resources than CEI. The Act will also permit LECs to enter into
new lines of business such as the long distance telephone business, and the sale
of television services over telephone lines, satellite or (in certain
circumstances) cable. CEI expects that any such new lines of business will be
more competitive and involve a higher degree of risk than CEI's traditional LEC
operations.

        There can be no assurance that CEI's business and profitability will not
be adversely affected as technological and regulatory changes permit new
competitors to access CEI's customer base and provide telecommunications
services within CEI's traditional local franchise area. In addition, there can
be no assurance that CEI will have the financial, technical or managerial and
other resources necessary to successfully invest, operate and compete in the new
business opportunities presented by these fundamental changes to the
telecommunications industry.

Effect of Regulation

        CEI's local exchange telephone subsidiaries, CTT and BVT, are subject to
a rate making process regulated by the Pennsylvania Public Utility Commission
(the "PaPUC"). Consequently, the ability of CEI's telephone subsidiaries to
generate increased income and cash flow is largely dependent on their ability to
increase their subscriber base, obtain higher message volumes and control their
expenses. The PaPUC continually reviews the appropriateness of the earnings of
public utilities. Consequently, the PaPUC could at any time initiate a review of
the appropriateness of the earnings of CTT or BVT and take action concerning
their rates.

                                      -14-
<PAGE>
 
        An amendment to the Pennsylvania Public Utility Act passed in 1993,
commonly referred to as Chapter 30, provides for streamlined rate regulation and
a method for determining rates other than the rate base/rate of return
regulation and procedures traditionally provided for in the Pennsylvania Public
Utility Act. Chapter 30 provides for what are being called "price caps" under a
price stability mechanism in which a telephone company's annual revenues from
non-competitive services may be permitted to increase or decrease from the
previous year's total as a result of price changes based upon the annual change
in the gross domestic product price index, as calculated by the United States
Department of Commerce, minus a productivity offset, with no limitation on the
profits or losses that may be earned by a regulated telephone company. In order
to avail itself of the changed rate determination procedures permitted by
Chapter 30, the utility must commit itself to provide universal broadband
services by 2015. Broadband services are defined as a "communication channel
using any technology and having a bandwidth equal to or greater than 1.544
megabits per second." The PaPUC is exerting substantial pressure on the LECs to
avail themselves of the alternate pricing procedure provided in Chapter 30.
Although CEI is evaluating its alternatives under Chapter 30, it has not yet
determined whether it wishes to avail itself of the Chapter 30 alternate pricing
procedures and what effect such pricing would have upon CEI and its LEC
subsidiaries, if elected. The effect of complying with Chapter 30 on the
earnings and profits of CEI cannot now be determined.

Limited Trading Market for CEI Common Shares

        CEI's Common Shares are listed on the NASDAQ Small Cap Market, which
market provides a trading market for CEI Common Shares. Since CEI Common Shares
were listed with NASDAQ in June 1994, an average of 18,758 shares have traded
each month. Because of such limited trading, sales of significant amounts of CEI
Common Shares may be difficult and any such sales might have a material adverse
effect upon the prevailing market price for CEI Common Shares.

Personal Communication Services

        In March 1995, CEI and Infocore formed Conestoga Wireless Company
("CWC"). CEI owns 60%, and a wholly owned subsidiary of Infocore, Infocore
Wireless, owns 40% of CWC. CWC was formed to bid in the Federal Communication
Commission's ("FCC") auctions for personal communication service ("PCS")
bandwidth. PCS is a wireless communications service based on lower power and a
higher frequency bandwidth than cellular service. It is anticipated to be more
reliable, of better quality and less expensive than cellular.

        CWC was a successful bidder in the FCC auctions for PCS in the basic
trading areas of Reading, Pottsville, Sunbury and Williamsport, Pennsylvania,
which cover nine (9) counties in Southeastern and Central Pennsylvania with a
population of 840,000. It is anticipated that the licenses will be issued to CWC
by June 1, 1997.

        CEI anticipates spending as much as $17,000,000 during 1997 to develop
portions of its PCS system. The total cost over ten (10) years fully to develop
the system is estimated to be as much as $45,000,000. As the result of the
acquisition of Infocore, CEI will bear the entire financial burden and risk of
building and implementing the PCS system.

        CEI anticipates funding CWC's 1997 PCS expenditures through internally
generated earnings, liquidation of certain investment assets and borrowing. CEI
anticipates funding the balance of the costs of PCS through internally generated
earnings, borrowing or raising additional equity.

        PCS will be a highly competitive business. CWC will compete with
cellular service providers and other PCS service providers throughout its entire
PCS license area. At least three service providers have licenses or systems to
compete with CWC in each part of its PCS license area. The PCS system will be in
competition with cellular service which is already well established in its
entire license area.

        The implementation of CWC's PCS business will involve the start up of a
new business in wireless communication. There do not exist historical financial
statements from which to prepare pro forma financial

                                      -15-
<PAGE>
 
statements with respect to such business. The start-up of CWC's PCS business is
a venture for which there can be no assurance of success.

Effect of Substantial Indebtedness and Preferred Stock on Future Operations

        At December 31, 1996, CEI had approximately $28 million of long-term
debt outstanding and approximately $12.8 million of $3.42 Series A Convertible
Preferred Shares, as compared to approximately $63.1 million of common
shareholder equity. This resulted in a ratio of debt and preferred stock to
equity of approximately 40%/60%. CEI will incur substantial additional
indebtedness in order to develop and construct the PCS system and infrastructure
with the probable result that the ratio of debt and preferred stock to equity
will be weighed even more heavily in favor of debt and preferred stock.

        Although such a level of debt and preferred stock is not unusual in the
telephone industry, such additional debt combined with the existing and
preferred stock will have important consequences on CEI's future operations,
including (i) CEI will incur significant interest expense along with significant
preferred stock dividend and principal repayment obligations, (ii) CEI is
subject to significant unscheduled preferred stock redemption obligations
because the outstanding CEI $3.42 Series A Preferred Shares may be "put" by the
holders thereof beginning in June 1998; (iii) CEI's increased leverage may make
it more vulnerable to economic downturns and reduce its flexibility in
responding to changing business and economic conditions; and (iv) payment of
dividends on CEI Common Shares, or future increases in the dividend rate on CEI
Common Shares, may be restricted by covenants in CEI's debt instruments or by
the level of financial resources needed to service CEI's additional debt and
preferred stock.

Dilution to Earnings

        The purchase price being paid by CEI in the Merger with Infocore is in
excess of the current book value of Infocore's assets. This purchase price in
excess of Infocore's book value will be accounted for by CEI as "goodwill",
which will be amortized over a period not to exceed ten (10) years. This
goodwill amortization will each year result in a non-cash charge to CEI's
reported earnings. It is possible, therefore, that if the Merger is consummated,
reported earnings per CEI Share will be diluted below present earnings levels.
See "SUMMARY--Selected Historical Financial Data."
 
        In addition, the financing of the costs of implementing the PCS system
is also likely to have a dilutive effect upon CEI earnings per share. The
interest costs of borrowings to finance the PCS system will be substantial and
are likely initially to lower reported earnings. If additional CEI stock is sold
for equity financing, such additional stock is likely to lower the reported
earnings per CEI share.  Furthermore, the loss of the income from any
investment assets sold to finance the implementation of PCS could also have a
dilutive effect on CEI's earnings.

Dividend Policy

        CEI has paid quarterly dividends since 1990. CTT paid dividends from
1909 through 1989. CEI does not intend to alter this policy in the foreseeable
future. However, as a holding company, CEI's ability to pay dividends on its
common stock and preferred stock will be dependent upon, among other factors,
its earnings, financial condition and cash requirements at the time such payment
is considered, and the payment of dividends to CEI by its subsidiaries. CEI's
local exchange telephone subsidiaries, CTT and BVT, are subject to rate
regulation by the PaPUC, and the amount of earnings and dividends of such
subsidiaries may be affected by such regulation. The dilutive effect of the
acquisition of Infocore and, even more significantly, the dilutive effect of the
implementation of CWC's PCS system could have a significant impact upon CEI's
continued ability to pay, or increase, dividends. See "RISK FACTORS--Effect of
Regulation."

Regulated/Nonregulated Revenue Mix

        The proportion of CEI's revenues derived from its nonregulated
activities have been increasing in recent years. It increased from 11.6% in 1994
to 13.9% in 1996. Infocore's revenues are wholly nonregulated. The

                                      -16-
<PAGE>
 
addition of Infocore's revenues to CEI's revenues in 1996 would have increased
CEI's 1996 nonregulated revenues to approximately 27%. PCS revenues will also be
nonregulated revenues. Consequently, as CWC's offering of PCS services goes on
line, an increasing portion of CEI's revenues will be derived from its
nonregulated business.

        The shift from regulated to nonregulated revenues will afford CEI the
opportunity for higher rates of return from prices that are not limited by PaPUC
regulation. However, at the same time such shift will expose CEI to fluctuating
rates of return from prices governed by market forces, not regulation. The
regulated revenue base of CTT and BVT, even with the advent of competition, has
provided CEI with a relatively stable earnings base. With the growth of CEI's
nonregulated business, this stable earnings base will increasingly constitute a
smaller portion, and the fluctuating earnings base governed by market forces a
greater portion, of the revenues of CEI and its subsidiaries. As a result of
such shift, CEI will be more vulnerable to competition and economic downturns
which may reduce its ability to respond to changing business and economic
conditions. Consequently, the payment of dividends on CEI's Common Shares, or
future increases in the dividend rate on CEI Common Shares, could be impacted by
the revenue shift from regulated to nonregulated revenues.

Integration of the Operations of Infocore and CEI

        As with any acquisition, there will be a period of substantial
adjustment as the management and employees of Infocore become integrated with
those of CEI. The businesses of Infocore and CEI are quite different. CEI
basically provides land line telephone services to many subscribers. Infocore
provides what are essentially consulting services to a much smaller customer
base.

                             THE INFOCORE MEETING

General

        This Joint Proxy Statement/Prospectus is being furnished to holders of
Infocore Common Shares in connection with the solicitation of proxies by the
Infocore Board to be used at the Infocore Meeting or any adjournment thereof.

        A proxy card has been enclosed with the Joint Proxy Statement/Prospectus
for use by holders of Infocore Common Shares.

        The Meeting will be held on Monday, April 21, 1997, at 10 a.m., local
time, at 661 Moore Road, King of Prussia, Pennsylvania 19406.

Matters to be Considered at the Infocore Meeting

        At the Infocore Meeting, shareholders of Infocore will consider and vote
upon a proposal to approve and adopt the Merger Agreement. Shareholders of
Infocore will also consider such other matters as may properly come before the
Infocore Meeting or any adjournment thereof.

        If the Merger Agreement is not approved at the Infocore Meeting, it is
anticipated that Infocore's annual shareholders' meeting would be held in July
1997. If the Merger is approved, it is not anticipated that Infocore would hold
its 1997 annual meeting unless the Merger Agreement is terminated.

Infocore Record Date; Shares Outstanding; Quorum

        Only shareholders of record of Infocore at the close of business on 
April 7, 1997 (the "Infocore Record Date"), will be entitled to receive notice
of the Infocore Meeting, and only holders of record of Infocore Common Shares as
of the Infocore Record Date will be entitled to vote at the Infocore Meeting. At
the close of business on April 7, 1997, there were issued and outstanding
5,778,956 Infocore Common Shares, and outstanding options to acquire an
additional 921,731 Infocore Common Shares. Each Infocore Common Share entitles
the holder to one vote. The presence at the Infocore Meeting, in person or by
proxy, of shareholders entitled to cast a majority of the votes at the Infocore
Meeting will constitute a quorum at the Infocore Meeting.

Vote Required

        Pursuant to the applicable provisions of the PBCL and Infocore's bylaws
(the "Infocore Bylaws"), the affirmative vote of a majority of the outstanding
Infocore Common Shares present and entitled to vote at the Infocore Meeting is
required to approve the Merger Agreement.

        As of the Infocore Record Date, directors and executive officers of
Infocore were the beneficial owners of approximately 1,228,004 Infocore Common
Shares, or approximately 21.24% of the outstanding Infocore Common Shares
entitled to vote at the Infocore Meeting, and such persons also held options to
acquire an additional 719,000 Infocore Common Shares. See "BUSINESS OF 
INFOCORE--Security Ownership of Certain Beneficial Owners and Management of
Infocore." The directors and executive officers of Infocore have indicated that
they intend to vote all such shares in favor of the Merger Agreement.

        Effect of Abstentions

        Holders of Infocore Common Shares entitled to vote at the Infocore
Meeting may withhold authority to vote on the Merger Agreement. Such abstention
will be considered as shares present and entitled to vote at the Infocore
Meeting, for the purposes of determining the quorum and the required vote for
approval of the Merger Agreement, but will not be counted as votes cast in the
affirmative. Therefore, abstentions by holders of Infocore Common Shares will
have the effect of a vote against the Merger Agreement.

                                      -18-
<PAGE>
 
Voting, Revocation and Solicitation of Proxies

        All Infocore Common Shares represented by properly executed proxies
received in time for the Infocore Meeting will be voted at the Infocore Meeting
in the manner specified by the holders thereof, unless such proxies have been
revoked prior to the vote. Proxies which do not contain voting instructions will
be voted for approval of the Merger Agreement.

        It is not expected that any matter other than those referred to herein
will be brought before the Infocore Meeting. If, however, other matters are
properly presented, the persons named as proxyholders will vote in accordance
with their judgment with respect to such matters. In the event that Infocore's
management desires to adjourn the Infocore Meeting in order to solicit
additional votes in favor of the Merger, the persons named in the Infocore proxy
card shall not be permitted to use the discretionary authority granted by such
proxy card to vote in favor of any such adjournment any Infocore shares which
were voted against the Merger.

        A shareholder who executes and returns a proxy on the enclosed form has
the power to revoke it at any time before it is voted. The giving of a proxy
does not affect the right of shareholders to attend the Infocore Meeting and
vote in person. A shareholder's presence at the Infocore Meeting, however, will
not in itself revoke the shareholder's proxy. A shareholder may revoke a proxy
at any time prior to its exercise by filing with the Secretary of Infocore, at
or before the Infocore Meeting, a duly executed revocation or a proxy bearing a

     the Merger is not intended to be a complete description of all facts
     regarding the Merger and is qualified in all respects by reference to the
     Merger Agreement attached to this Proxy Statement/Prospectus as Appendix A

     Merger, see "SUMMARY--The Merger."

     Background of the Merger

          Infocore

          Infocore is a telecommunications company founded in 1981 which
     provides communication services to a variety of customers in Southeastern
     Pennsylvania.  It provides resale of long distance services, maintenance
     services for customers' communication systems and the design and
     installation of customers' communication systems.  It has also been active
     in the PCS area and has provided the expertise for the participation of CWC
     in the PCS auctions.

          Infocore Common Shares are not listed on the Nasdaq National Market,
     the Nasdaq Small-Cap Market or any stock exchange, and Infocore is not
     subject to the reporting requirements of the Exchange Act.  There is no
     market maker holding an inventory position in Infocore Common Shares, and
     the trading market for Infocore Common Shares is extremely thin.

          Historically, Infocore has operated in an extremely competitive
     environment.  It has operated in many ways as a consulting company and its
     primary attractiveness is the knowledge and expertise of its employees.

          Industry Overview

          In recent years, the telecommunications industry has been experiencing
     rapid and fundamental changes.  These changes have resulted from three
     long-term telecommunications industry trends: (i) rapid advancements in
     telecommunications technology; (ii) increasing demand for
     telecommunications services; and (iii) increased competition.

          Technological advancements in transmission capacity, including
     advancements in switching equipment, the development of digital systems,
     the development of fiber-optic cable, the advent of wireless technology
     such as cellular and PCS, and even the ability to enhance the capacity of
     basic twisted copper wire, have greatly increased the speed and delivery
     capability of the telecommunications infrastructure.  Technological
     developments in equipment and systems, including the advent of mobile
     telephones, computers, network software technologies, FAX, and the Internet
     with its world-wide computer web, have all greatly increased the demand for
     telecommunications services.  These changes are also blurring the divisions
     which formerly separated the computer, video, telephone, and cable
     television industries.

          The combination of advances in transmission and equipment technology
     will soon make possible the offering of a wide range of new, interactive
     broadband telecommunication services, including interactive video and
     enhanced data transmission, which may further enhance the demand for
     telecommunications services.  All of these changes create the opportunity
     for existing and new services to be delivered by a number of different
     service providers.  These changes provide growth opportunities to LECs, so
     long as (1) they have sufficient size and capital to make the necessary
     capital investments, (2) they can successfully operate in new markets that
     differ from traditional regulated telco operations; and (3) they have the
     manpower with the expertise to develop and provide the enhanced services
     and systems.

          Deregulation and competition are a principal focus of the
     telecommunications industry both at the Federal and state levels.  The LECs
     will be under pressure to give competitors access to their local loops and
     switching centers.  This could divert revenue from the LECs.  However, the
     LECs will still own their local loops and switches, and the time and cost
     of building competitive systems will be substantial.  The LECs will have
     the

                                      -20-
<PAGE>
 
     right to charge competitive amounts for such access, and such charges
     should reflect the cost for their competitors to build competitive systems.

          Although the shape of future telecommunications industry regulation
     cannot be predicted, it is likely that the incremental progress of
     deregulation will continue to open new markets to service providers.  As an
     example, in recent years, competitive access providers ("CAPs") and system
     bypass offered by long distance (interexchange or "IXC") carriers, have
     emerged to offer alternative access for the origination and termination of
     long distance calls based on the local loop.  These alternative access
     providers represent a competitive inroad into a significant source of LEC
     revenue--network access charges.

          The combination of technological innovation, increased demand and
     competition is greatly altering the telecommunications industry.  Without a
     doubt, the LECs will likely be faced with increasing challenges to their
     historical revenue base.  LECs will also have a variety of investment
     options in a changing technological, competitive and regulatory
     environment.  These investment options offer the opportunity to take
     advantage of the increasing demand for telecommunications services.


          Infocore Strategic Options

          In 1995, the Board of Directors and executive officers of Infocore
     identified wireless telephony as an area of major opportunity for the
     Company and formed a joint venture with CEI to pursue the ownership of
     broadband PCS licenses.  At the same time, management decided to re-focus
     on the sale and service of customer premise equipment as a continuing
     source of  profitability.  In the opinion of the Board of Directors, there
     were several strategic options to enhance shareholder value:  achieve
     accelerated growth in the company's core business by acquisition, or raise
     new equity to fund wireless ventures.  These options were constrained by
     Infocore's small size and limited access to capital.

          Since that time, however, the Board of Directors and executive
     officers have recognized that success in winning licenses to provide PCS
     services requires substantial capital for Infocore to preserve its equity
     ownership level in the wireless venture.  Extensive conversations with
     investment bankers have suggested that the company may have difficulty
     raising additional equity.  Efforts to identify suitable acquisitions have
     been unsuccessful.

     Merger Negotiations

          In December 1996, management of CEI and Infocore held preliminary
     discussions about the possibility of merging the two companies.  Because of
     shared values and traditions and similar views about the future shape of
     the telecommunications industry, there was consensus to continue exploring
     a possible merger.  The Infocore Board was apprised of these discussions
     during its regularly scheduled meeting on December 16, 1996.

          At a strategic planning session with Conestoga's Board on December 23,
     1996, CEI management determined that part of Conestoga's strategic plan
     would be to achieve growth through the acquisition of firms providing
     services within the telecommunications industry.  In that planning session
     it was also mentioned that the acquisition of Infocore might fit within
     such strategic plan.

          Management reviewed its discussion with Infocore at the monthly
     meeting of CEI Board on January 28, 1997.  The board discussed the
     possibility of acquiring Infocore and established a general range of the
     amount of stock it would be willing to exchange for all of the outstanding
     stock of Infocore.  The board gave management permission to pursue the
     negotiations with Infocore.

          Following further informal and formal discussions between management
     of the two companies, a special meeting of the Board of Directors of
     Infocore was held on February 6, 1997.  Infocore's legal counsel was
     present at this meeting.  The purpose of the meeting was to review the
     status of negotiations with CEI regarding the proposed business combination
     between CEI and Infocore and to authorize a special committee of the Board
     to assist in the evaluation and negotiation of a merger agreement between
     the two companies.  The Board members, with the input of counsel, discussed
     the appropriate decision-making process that the Board had to

                                      -21-
<PAGE>
 
     undertake in order to fulfill its fiduciary duties to Infocore and its
     shareholders in properly evaluating a proposed merger price with CEI.
     There was discussion that the engagement of an investment banker to render
     a fairness opinion was not desirable in this particular instance because of
     the difficulty in establishing market comparables with Infocore's business
     and the high cost of obtaining such an opinion in the context of  the
     relatively small purchase price for the business combination.  Management
     agreed to prepare and distribute to the Board a detailed evaluation of the
     expected range of merger prices in light of Infocore's financial results
     and industry, as well as publicly available financial and other information
     regarding CEI.

          On February 10, 1997, Messrs. Clement and Cenerazzo, as
     representatives of Infocore, and Messrs. Bentz and Kramer, on behalf of
     CEI, met at CEI's offices to negotiate the terms of the merger.  During the
     course of that meeting, the parties were able to resolve, through
     negotiation, all substantial issues relating to the merger transaction.

          The Board of Directors of CEI held a special meeting on February 10,
     1997 to consider the acquisition of Infocore.  CEI's legal counsel was
     present at the meeting.  The Board discussed the proposed acquisition in
     terms of the assets and value of Infocore to be acquired, the consideration
     CEI should pay and the conditions that should attach to the transaction.
     The Board authorized management to execute a letter of intent and a
     definitive merger agreement to acquire Infocore for 200,000 shares of CEI
     common stock provided that the principal officers of Infocore enter into
     acceptable employment agreements which include a covenant not to compete
     after the acquisition.
 
          Another special meeting of the Board of Directors of Infocore and its
     counsel was held on February 11, 1997.  The purpose of the meeting was to
     review current negotiations between Infocore management and CEI regarding
     their business combination and the proposed terms of the transaction.
     Management reviewed CEI's proposal that Infocore shareholders would receive
     200,000 shares of CEI common stock in the aggregate.  The Board extensively
     discussed whether the proposed terms of the merger transaction was a fair
     proposal and maximized value for Infocore's shareholders.  The Board
     unanimously resolved to approve the transaction with CEI upon the terms and
     conditions discussed during the meeting, and directed that the transaction
     be submitted to the shareholders of Infocore for their approval.

          A letter of intent between CEI and Infocore relating to the business
     combination was negotiated and executed on February 13, 1997.  Following
     the execution of the letter of intent, Infocore and CEI proceeded with the
     due diligence effort.  In connection with this due diligence review, CEI
     utilized the services of several professional organizations, including
     Miller and Murray, LLP, Beard and Company, Inc., its independent
     accountant, and JSI Financial Services.  The purpose of the due diligence
     program was to further evaluate Infocore's management team and various
     operational, financial and legal matters relating to Infocore.  In
     connection with this process, during the period from the middle of February
     through early March, 1997, several telephone conferences, meetings and
     facility site visits were scheduled by representatives of CEI with the
     management of Infocore.

          Simultaneous with the due diligence review of Infocore by CEI, counsel
     for CEI commenced the preparation of the Merger Agreement.  Following
     distribution and review of the first draft of such document,
     representatives of Infocore and CEI management and their counsel met on
     March 6, 1997 to negotiate the Merger Agreement.  The parties held several
     additional telephone conferences to continue their negotiation of the
     Agreement over the next several days.  The Merger Agreement was approved at
     an Infocore Board meeting held on March 10, 1997 and signed on March 14,
     1997, and its execution was announced by CEI on March 14, 1997 through a
     press release.

     Infocore's Reasons for the Merger; Recommendation of the Infocore Board of
     Directors

          The Infocore Board believes that the Merger will benefit  Infocore,
     its shareholders, employees and customers for the reasons discussed below.
     The Infocore Board believes that the proposed transaction with CEI offers
     Infocore's shareholders very favorable value for their Infocore shares, and
     liquidity of their investment.

          In reaching its determination and recommendations above, the Infocore
     Board considered a number of factors, including, without limitation, the
     following material factors:

          -    The Infocore Board's belief that, based on its familiarity with
               Infocore's business, financial condition, earnings and prospects,
               as well as the current conditions in the telecommunications
               industry, the terms of the Merger Agreement are attractive to
               Infocore shareholders.

          -    The Infocore Board's consideration of the fact that the Infocore
               shareholders have no market for the Infocore Common Shares and
               that the CEI Common Shares will be  publicly listed on NASDAQ,
               thereby providing a significant increase in the liquidity of the
               investment of Infocore shareholders.

          -    The fact that the Merger was structured to qualify as a tax-free
               exchange so that the Infocore shareholders will be able to
               convert their shares of Infocore stock into CEI Common Shares
               without incurring a federal income tax liability.

          -    The Infocore Board's review of the strategic option of remaining
               independent.  The Infocore Board concluded that Infocore would be
               at a competitive disadvantage as a small independent company in
               attempting to consummate acquisitions to expand its core
               business, as well as to finance its 40% ownership position in
               CWC.  The Infocore Board believed that there is a substantial
               risk of Infocore being unable to maintain its 40% ownership
               position in CWC in the future because of the substantial capital
               investment requirements which will accompany its build-out of the
               PCS system.

          -    The Infocore Board's consideration that from time to time in the
               past, there have been informal discussions between Infocore
               management and third parties about the possible acquisition of
               Infocore, and the merger consideration being offered by CEI was
               attractive in light of such prior discussions.  Based upon its
               experience, the Infocore Board did not believe that it was likely
               that attractive offers from additional potential acquirors would
               materialize.

          -    The Infocore Board's consideration of CEI's willingness to
               maintain the independent operations of Infocore and initially to
               retain the continued employment of all Infocore employees
               following the Merger. The Infocore Board believed that the career
               opportunities of Infocore employees will be enhanced by the CEI
               affiliation and that there appears to be a natural fit between
               Infocore and CEI in operational alignment, values and traditions.

          -    The Infocore Board's belief that most Infocore customers will
               continue to do business with the new entity because of the
               reputation of CEI and the wider range of communication services
               which Infocore will be able to offer in the future.

          The Infocore Board did not assign any specific or relative weights to
     the factors under its consideration.

          FOR THE FOREGOING REASONS, THE BOARD OF DIRECTORS OF INFOCORE BELIEVES
     THAT THE MERGER IS IN THE BEST INTERESTS OF INFOCORE SHAREHOLDERS, HAS
     APPROVED THE MERGER AGREEMENT AND RECOMMENDS THAT THE INFOCORE SHAREHOLDERS
     VOTE "FOR" APPROVAL OF THE MERGER AGREEMENT.

CEI's Reasons for the Merger

     The CEI Board believes that the Merger will benefit CEI, its shareholders
and employees and will also benefit the Infocore shareholders who receive CEI
Common Shares in the Merger. CEI's strategic long range plan includes growth
through acquisitions and participation in the expansion of the communications
industry and the developing technologies available thereto. The CEI Board
believes that the Merger offers CEI the opportunity to make a strategic
acquisition that, by increasing the telecommunication services it is capable of
offering and broadening its pool of talented telecommunication professionals,
will greatly increase the capacity of CEI to compete in a competitive market and
consequently increase the value of the CEI shares. CEI plans to operate Infocore
following the Merger as a stand-alone subsidiary. The CEI Board has concluded,
in view of the foregoing and the factors set forth below, that the Merger is in
the best interests of CEI. In reaching its determinations and recommendations
above, the CEI Board considered a number of factors, including, without
limitation, the following material factors:

          .    The CEI Board's strategic plan includes growth through the
               acquisition of service providers to the telecommunication
               industry, including firms like Infocore.

          .    The CEI Board's belief, based on its familiarity with the
               business of CEI and Infocore, and the combined financial
               conditions, earnings and prospects of the two companies, as well
               as the current conditions in the telecommunications industry,
               that the terms of the Merger Agreement are attractive to CEI
               shareholders.

          .    The CEI Board's belief that the addition of Infocore's
               telecommunications services offerings, areas of expertise, and
               pool of talented employees will enable CEI and Infocore in
               combination better to take advantage of many of the opportunities
               currently available in the telecommunications industry, such as
               becoming a PCS provider, providing ISDN and other broadband
               services to their subscribers and expanding data communication
               services, while at the same time achieving cost savings due to
               economies of scale.

          .    The CEI Board's belief that the provision of PCS services through
               a wholly owned subsidiary, CWC, combined with the knowledge and
               expertise of Infocore's employees in the procurement, development
               and marketing of PCS, will greatly enhance CEI's ability
               successfully to provide PCS services.

          .    The CEI Board's confidence in, and respect for, the talented
               employees of Infocore who will be able to make a major
               contribution to CEI's future growth and economic well-being.

          .    The opinion of JSI Financial Services that as of the date of such
               opinion (March 14, 1997), the consideration to be paid pursuant
               to the Merger was fair, from a financial point of view, to the
               shareholders of CEI.  The written opinion of JSI Financial
               Services, updated as of the date of this Proxy
               Statement/Prospectus, is reproduced in full as Appendix C hereto,
               and CEI's shareholders are urged to read the opinion carefully in
               its entirety.  See "THE MERGER--Opinion of CEI Financial
               Advisor."

The CEI Board did not assign any specific or relative weights to the factors
under its consideration.

     FOR THE FOREGOING REASONS, THE BOARD OF DIRECTORS OF CEI BELIEVES THAT THE
MERGER IS IN THE BEST INTERESTS OF CEI SHAREHOLDERS; HAS ENTERED INTO THE MERGER
AGREEMENT; AND HAS APPROVED THE ISSUANCE OF CEI COMMON SHARES TO THE INFOCORE
SHAREHOLDERS IN THE MERGER.

Opinion of CEI Financial Advisor


     CEI retained JSI Financial Services ("JSI") to act as its financial advisor
in connection with a potential purchase of Infocore, to consider the proposed
consideration offered by CEI (the "Consideration") and to provide an opinion as
to the fairness, from a financial point of view, to the CEI shareholders of the
Consideration to be paid in the Merger.  JSI was selected to act as CEI's
financial advisor based upon its qualifications, expertise and reputation as an
advisor to firms engaged in the telecommunications industry.

     JSI provides business and financial intermediation, valuation, strategic
and business planning, and syndication services to clients in the
telecommunications, broadcasting and cable industries.  JSI has performed
valuations of telecommunications concerns for a variety of purposes, including
mergers and acquisitions, divestitures, gift and estate taxes, employee stock
ownership plans, financial restructurings, and other objectives.

     On March 14, 1997, JSI delivered its opinion to CEI that, based upon and
subject to the considerations set forth therein, as of such date the
Consideration to be paid to the shareholders of Infocore by CEI pursuant to the
Merger Agreement was fair, from a financial point of view, to the shareholders
of CEI.  This opinion (the "JSI Opinion"), was updated as of the date of this
Proxy Statement/Prospectus.  The JSI Opinion is based upon economic, market and
other conditions in effect as of the date thereof.  No limitations were imposed
by the CEI Board upon JSI with respect to the investigations made or procedures
followed by them in rendering the JSI Opinion.  The JSI Opinion, which sets
forth assumptions made, material reviewed, matters considered and limits on the
review, is attached hereto as Appendix C to this Proxy Statement/Prospectus and
is incorporated herein by reference.  JSI has consented to the inclusion of its
opinion in this Proxy Statement/Prospectus and has reviewed the following
summary of its opinion.

     In rendering its opinion, JSI, among other things, considered (i) the
nature and economic outlook of the telecommunications industry; (ii) the
financial and operating history of CEI and Infocore; (iii) CEI's and Infocore's
earnings and cash flow for the last three years and management's assessment of
future earnings and cash flow; (iv) price and trading ranges for CEI Common
Shares over the prior 33 months; and (v) the estimated  value of identifiable
assets and benefits associated with the Infocore acquisition.

     In rendering the opinion, JSI reviewed specific documents, relied upon
information and performed procedures as follows: (i) reviewed CEI's and
Infocore's audited financial statements for the periods December 31, 1994
through December 31, 1996; (ii) reviewed Securities and Exchange Commission
Forms 10-K filed by CEI for the fiscal years ending December 31, 1991 through
December 31, 1995; (iii) reviewed the history of CEI's stock transfer prices for
the period June 1, 1994 through March 14, 1997; (iv) reviewed the Merger
Agreement; (v) had discussions with CEI management about the Merger and current
and future business prospects for both CEI and Infocore; and (vi) performed such
other analysis and considered such other factors as it deemed appropriate.

     In rendering their opinion, JSI relied, without independent verification,
on the accuracy and completeness of all financial and other information that was
publicly available or furnished to it by CEI, Infocore and/or their advisors.

     Nature and Economic Outlook Of The Telecommunications Industry.  In
     --------------------------------------------------------------     
rendering their opinion, JSI considered the nature and economic outlook of the
telecommunications industry.  It pointed out that since the divestiture of AT&T
in 1984, LECs have experienced significant revenue growth due, in large part, to
the imposition of a federal access charge structure and cost recovery system
which provides for the regulated returns of the LECs.  This, in addition to
advances in technologies and services (e.g., digital switching, distribution
over fiber optic cable, and enhanced regulated and unregulated service offerings
as a result of enhanced switching capabilities), subscriber growth due to
increasing population, access line growth due to increasing demands from
existing subscribers (e.g., home facsimile machines and Internet access), and
decreasing operating cost structures due to technological and system advances,
as well as efficiencies due to economies of scale, have enhanced the
profitability of telecommunications properties.

     JSI stated that it continues to believe that the outlook for continued
growth and expansion of independent telephone companies appears favorable for a
number of reasons.  First, subscribership will continue to grow as the
telecommunications needs of end users expand.  The widespread use of the
Internet, data communications, wireless services, and broadband services will
expand the use of the telecommunications network.  Second, as technology
improves and new services continue to be brought to market, the provider of
those services will continue to grow.  The direct link that the LEC has to the
end user well positions the LEC to be the primary future provider of
telecommunications services.  Third, as competition becomes a reality in the LEC
market, there is room for the LECs to grow.  As the regulatory environment moves
to a more competitive nature, the ability for more rural LECs to expand into
more urban markets as a competitive local exchange carrier (CLEC) is enhanced.
Rural LECs already have the switching network (usually with digital capacity),
existing operational systems and infrastructure, a distribution network (which
is increasingly fiber optic), and the management know-how to successfully
compete in these areas.

     The acquisition of Infocore should support CEI's growth and expansion into
the areas of opportunity described above.  Infocore with its experience in data
communications and wireless services has technical expertise that can assist CEI
to take advantage of such expanded use of the telecommunications network  and
help CEI make such new technology and services available to its customers.

     JSI reported that it considered the current nature and economic outlook of
the telecommunications industry, as well as the nature of the services rendered
by Infocore and economic outlook therefor when arriving at its opinion regarding
the overall fairness of the Merger Agreement.  It reviewed the competitive
threats presented both by emerging competitive technologies, such as PCS, and
threats posed by federal and state legislative initiatives to deregulate the
local telephone business.  It acknowledged the competitive threat technological
and regulatory developments pose to the independent LEC's traditional monopoly,
but posited that such developments will only enhance, in the long-run, the
inherent value of communications properties, provided such properties are
properly managed and strategically positioned for the future.  It stated its
belief that a continually increasing customer base and entering related but non-
traditional lines of business are core strategies for the communications
provider of tomorrow and reported that CEI's management has articulated a
strategy consistent with this belief, including growth, both within the
telephone industry, as well as into other businesses, such as PCS, through
acquisition and internal growth.  JSI perceives CEI's management to be well
positioned to seize the opportunities of the future communications business.
The Merger with Infocore will assist CEI's efforts to enter related lines of
business.  Accordingly, JSI concluded that the current nature and economic
outlook of the telecommunications industry reflected favorably upon the Infocore
acquisition.

     CEI's and Infocore's Financial and Operating History.  JSI reviewed the
     ----------------------------------------------------                   
financial and operating history of CEI and Infocore to gain appreciation of the
operational benefits and synergies of the Merger.  JSI stated its belief that
the Merger would provide benefits to CEI through the addition of management with
enhanced experience in non-traditional but related lines of business.  JSI also
stated its belief that the association will benefit Infocore through enhanced
exposure to CEI's customer base and the expansion of distribution channels for
its traditional services.

     CEI's and Infocore's Earnings and Cash Flow Analysis.   JSI reviewed recent
     ----------------------------------------------------                       
financial and operating performance of CEI and Infocore and discussed the
anticipated impact of the Merger on consolidated earnings and cash flow with
CEI's management. The focus of JSI's review of earnings and cash flow was to
determine the impact the Merger would have on CEI's earnings per share.
Projections provided by CEI management indicated the Merger would not dilute
CEI's projected 1997 earnings per share.

     Estimated Value of Identifiable Assets and Benefits.  JSI reviewed the
     ---------------------------------------------------                   
overall fairness of the Consideration paid pursuant to the Merger by subtracting
from the aggregate consideration paid the estimated value of certain
identifiable assets and benefits to arrive at net consideration paid for the
Infocore operations.  Identifiable assets and benefits included excess cash
above amounts considered necessary to support Infocore's operations,  Infocore's
40% ownership of CWC, and Infocore's available tax loss carryforwards.  The net
consideration paid for Infocore's operations was then compared to a valuation of
Infocore's operations based on traditional capitalization of earnings methods of
valuation.

     Additional Analysis and Other Factors Considered.  JSI performed other
     ------------------------------------------------                      
analyses and considered such other factors as it deemed necessary in coming to
an opinion on the overall fairness of the Merger to the CEI common shareholders.
The material procedures and factors were:

     1.  JSI considered the use of other traditional methods of valuation
including guideline company and discounted future income techniques.  However,
given the satisfactory results of other analyses performed, the lack of reliable
financial data for guideline companies comparable in size and operating nature
to Infocore, and the size of the Merger relative to the total capitalization of
CEI, such alternative valuation methods were not deemed necessary.

     2.  The potential for an association with CEI to enhance the profitability
of Infocore.   JSI believed that the consolidation of Infocore's and CEI's
operations would result in enhanced future revenue opportunities for the
combined entity.

     3.  JSI believed that Infocore's management and professional team is
capable and able to assist CEI in post-acquisition operational issues,
particularly with respect to the build-out and operation of CEI's PCS properties
and entry into related, non-traditional lines of business. The existence in
place of Infocore's management team was a positive influence on JSI's overall
conclusion.

     In arriving at its Opinion, JSI considered the factors outlined above as
well as other factors salient to the transaction.  This summary does not purport
to be a complete description of the analysis performed by JSI pursuant to its
engagement; the foregoing paragraphs, however, reflect all material analyses
performed by JSI.  The preparation of a fairness opinion involves various
determinations as to the most appropriate and relevant methods of financial
analysis and the application of those methods to the particular circumstances.

     Based on the foregoing analysis, JSI rendered the opinion that, as of the
date of this Proxy Statement/Prospectus, the Consideration to be paid pursuant
to the Merger is fair, from a financial point of view, to the shareholders of
CEI.

     Terms of the Merger

          Effect of the Merger

          Pursuant to the Merger Agreement, Infocore will be merged with and
     into Merger Sub, with Merger Sub as the surviving entity (sometimes
     referred to as the "Surviving Corporation") and a wholly owned subsidiary
     of CEI, and the separate corporate existence of Merger Sub with all its
     rights, privileges, immunities, powers and franchises shall continue
     unaffected by the Merger.  The shares of common stock of Merger Sub issued
     and outstanding immediately prior to the Effective Time will remain
     outstanding and unchanged after the Merger, and will thereafter constitute
     all of the issued and outstanding capital stock of the Surviving
     Corporation.  The articles of incorporation and bylaws of Merger Sub in
     effect immediately prior to the Merger will remain in effect as the
     articles of incorporation and bylaws of the Surviving Corporation, except
     that Article I of the articles of incorporation will be amended to read as
     follows:  "The name of the corporation is Infocore, Inc."  The directors
     and officers of Merger Sub immediately prior to the Merger will remain in
     office as the directors and officers of the Surviving Corporation.

          Merger Consideration

          In connection with the Merger, each Infocore Common Share outstanding
     as of the Effective Time, other than Infocore Common Shares held by persons
     who have perfected dissenters' rights, will be converted into and become a
     right to receive CEI Common Shares. For a description of the CEI Common
     Shares, see "DESCRIPTION OF CAPITAL STOCK OF CEI."

          Closing; Effective Time

          The Merger Agreement provides that the Closing of the Merger will
     occur on a mutually agreeable date no later than the fifth business day
     after satisfaction or waiver of certain conditions set forth in the Merger
     Agreement (the "Closing Date").  See "THE MERGER--Terms of the Merger--
     Conditions to the Merger."  On the Closing Date, or as soon thereafter as
     practicable, the parties will execute and file in the office of the
     Corporation Bureau of the Commonwealth of Pennsylvania appropriate articles
     of merger (the "Articles of Merger") in accordance with the provisions of
     the PBCL.  The Merger will become effective (the "Effective Time") upon the
     filing of the Articles of Merger, or the effective date specified therein,
     whichever is later.

          Representations and Warranties

          Infocore, CEI and Merger Sub have made certain customary
     representations and warranties as set forth in the Merger Agreement.  The

     of, and absence of false information in, reports filed with the Commission.

          Conduct of Business Pending the Merger

          Infocore has agreed that (except as expressly contemplated or
     permitted by the Merger Agreement or to the extent that CEI otherwise
     consents in writing), between the date of the Merger Agreement and the
     Effective Time (a) it will conduct its business in the ordinary course,

     the Infocore 1991 Stock Option Plan; (h) it will not incur or guarantee any

          Certain Covenants

          Pursuant to the Merger Agreement, each of Infocore and CEI has agreed,
     from the date of the Merger Agreement to the Effective Time, (a) to
     promptly inform the other party in writing if any information set forth in
     the schedules called for in the Merger Agreement is not accurate or
     complete in all material respects; (b) that Infocore will give CEI
     reasonable access to its personnel, properties, books, contracts, documents
     and records; (c) to obtain all consents, approvals and authorizations
     required by the Merger Agreement; (d) to use reasonable best efforts to
     satisfy all conditions of the Merger Agreement; and (e) to refrain from
     making, issuing or releasing any public announcements concerning the Merger
     without making a good faith effort to inform the other party.

          Pursuant to the terms of the Merger Agreement, Infocore has agreed (a)
     to call and hold a meeting of its shareholders for the purpose of voting on
     the Merger Agreement; (b) prior to the Closing Date, to deliver to CEI
     letters regarding affiliates for purposes of Rule 145 under the Securities
     Act; and (c) to provide CEI with all proxy materials which Infocore intends
     to use in connection with the Merger.

          Pursuant to the terms of the Merger Agreement, CEI has also agreed (a)
     to file the Registration Statement with the SEC to register the CEI Common
     Shares to be issued in the Merger, and use its reasonable best efforts to
     cause the Registration Statement to become effective; (b) to file all
     applicable state securities applications and use its reasonable best
     efforts to qualify the CEI Common Shares to be issued in such states; and
     (c) to file an application with the Nasdaq Small Cap Market to list the CEI
     Common Shares issuable in connection with the Merger, and to use its
     reasonable best efforts to obtain approval of such application upon
     official notice of issuance.

          Employment Contracts with Infocore Employees

          In the Merger Agreement and employment contracts referenced therein,
     Merger Sub has agreed to employ Harrison H. Clement, Jr., President and
     Chief Executive Officer of Infocore, and Henry M. Stringer, Senior Vice
     President of Infocore, for a period of two years following the Effective
     Date at their current salaries.  They may only be terminated during such
     period for due cause.  During this two year period, Merger Sub has agreed
     to provide them with the same benefits they are receiving from Infocore or
     with benefits comparable thereto.  The agreements also provide that, if
     during such two year period a third party acquires control of CEI, Harrison
     H. Clement, Jr. would be entitled to receive his salary for eighteen months
     after his termination of

                                      -26-
<PAGE>
 
     employment within such two year period and Henry M. Stringer a salary for
     twelve months thereafter.  In turn, Messrs. Clement and Stringer agree not
     to compete with CEI and its subsidiaries in the wireless business in the
     CWC PCS license area during such two year period and not to solicit the
     customers of CEI and its subsidiaries for one year after the termination of
     their employment.

          No Solicitation; Pursuit of Other Transactions

          In the Merger Agreement, Infocore has agreed that, except as described
     below, it will not, nor will it authorize any of its officers, directors,
     employees, affiliates, investment bankers or other representatives or
     agents to, directly or indirectly, solicit, encourage (including by way of
     furnishing non-public information), initiate discussions or negotiations
     relating to or take any other action to facilitate, any inquiries or the
     making of any proposal for an "Acquisition Transaction," which is defined
     in the Merger Agreement to mean the occurrence of any of the following
     events:  (i) Infocore is acquired by merger or otherwise by any person or
     group, other than CEI, Merger Sub or any of their respective affiliates (a
     "Third Party"); (ii) a Third Party acquires more than 30% in value of the
     assets of Infocore; (iii) a Third Party acquires more than 30% of the
     outstanding Infocore Common Shares; (iv) Infocore adopts and implements a
     plan of liquidation relating to, or extraordinary dividend equal to, more
     than 30% in value of the assets of Infocore; or (v) Infocore enters into a
     preliminary or definitive agreement with a Third Party relating to any of
     the transactions referred to in clauses (i) through (iv) above.  Infocore
     has agreed promptly to notify CEI orally and in writing of any inquiries or
     proposals regarding an Acquisition Transaction.

          Infocore, however, is permitted to disclose information to, and to
     engage in discussions and negotiations concerning an Acquisition
     Transaction with, a person who makes a bona fide offer to engage in an
     Acquisition Transaction for consideration and on terms which are more
     favorable to the Infocore shareholders than the terms of the Merger, and
     who can reasonably be expected to consummate the Acquisition Transaction on
     the terms that have been proposed, and which disclosure, discussions and
     negotiations shall be required by reason of the fiduciary obligations of
     the directors of Infocore.

          In addition, Infocore is permitted, subject to its obligations to pay
     CEI a termination fee, to terminate the Merger Agreement and accept an
     offer for an Acquisition Transaction which the Infocore Board concludes is
     more favorable to the Infocore shareholders than the Merger.

          Conditions to the Merger

          The obligations of Infocore, CEI and Merger Sub to consummate the
     Merger are subject to, among other things, the satisfaction of the
     following conditions: (a) the performance by Infocore, CEI and Merger Sub
     of their respective obligations under the Merger Agreement and the accuracy
     of their respective representations and warranties contained therein; (b)
     approval of the Merger Agreement and the transactions contemplated thereby
     by the shareholders of Infocore; (c) Harrison H. Clement, Jr., President
     and Chief Executive Officer of Infocore and Henry M. Stringer, Senior Vice
     President of Infocore, having executed and delivered to CEI employment
     agreements; (d) the absence of any injunctions which would prevent the
     consummation of the transactions contemplated by the Merger Agreement; (e)
     the absence of any action, suit or proceeding against Infocore or CEI
     brought by the Antitrust Division of the Department of Justice (the
     "Antitrust Division") or the Federal Trade Commission (the "FTC")
     challenging the Merger under federal antitrust laws; (f) the listing on the
     NASDAQ Small Cap Market of the shares of CEI Common Stock issuable in
     connection with the Merger; and (g) the effectiveness of the Registration
     Statement and the absence of stop orders suspending the effectiveness.

          The obligations of CEI and Merger Sub to consummate the Merger are
     further subject to: (a) the receipt by CEI of letters from Infocore's
     affiliates for purposes of Rule 145 under the Securities Act; (b) the
     exercise of dissenters' rights by no more than 10% of the outstanding
     Infocore Common Shares; (c) the receipt by CEI of an opinion dated the
     Closing Date from Saul, Ewing, Remick & Saul, counsel to Infocore, in form
     and substance reasonably satisfactory to CEI and its counsel; (d) the
     receipt by CEI of the written resignations of those Infocore directors and
     officers designated by CEI; and (e) all outstanding stock options granted
     by Infocore pursuant to the Infocore 1991 Stock Option Plan having been
     either (i) exercised and Infocore Common Stock issued pursuant thereto; or
     (ii) effectively and conclusively relinquished and terminated by the
     optionees. The

                                      -27-
<PAGE>
 
     obligations of Infocore to consummate the Merger are subject to the receipt
     of an opinion from Saul, Ewing, Remick & Saul, tax counsel to Infocore, as
     to certain tax matters.

          The obligations of CEI to consummate the Merger is subject to the
     receipt by CEI of the written opinion of JSI Financial Services that the
     consideration to be paid by CEI in the Merger is fair to CEI's shareholders
     from a financial point of view and to such opinion not being withdrawn
     following the mailing of this Proxy Statement/Prospectus.

          Waiver; Amendment

          Prior to the Effective Time, any provision of the Merger Agreement may
     be:  (a) waived by the party benefitted by the provision, by board of
     directors or authorized officer action, if in the judgment of such board or
     such officer such waiver would not have a material adverse effect on the
     benefits intended to its shareholders; or (b) amended or modified at any
     time by an agreement in writing duly authorized and executed by each of the
     parties, except that after approval of the Merger Agreement by the
     shareholders of Infocore or CEI, no amendment which by law requires
     approval by the shareholders of Infocore or CEI may be made without such
     shareholder approval.

          Termination

          The Merger Agreement provides that, notwithstanding approval by the
     shareholders of Infocore, the Merger Agreement may be terminated and the
     transactions contemplated in the Merger Agreement abandoned at any time
     prior to the Closing Date:  (a) by mutual consent of CEI and Infocore, or
     (b) by either Infocore or CEI in the event (i) of a material breach by the
     other party of any representation, warranty, covenant or agreement
     contained in the Merger Agreement, or (ii) if the Effective Time shall not
     have occurred on or by November 1, 1997, unless the failure to do so is due
     to the breach of the Merger Agreement by the party seeking to terminate or
     the parties agree to extend the Effective Time beyond such date.

          Infocore may terminate the Merger Agreement, subject to its
     obligations to pay the termination fee described below, in order to accept
     an offer for an Acquisition Transaction which the Infocore Board concludes
     is more favorable to the Infocore shareholders than the Merger.

          Fees and Expenses

          Except as set forth below, whether or not the Merger is consummated,
     all costs and expenses incurred in connection with the Merger Agreement and
     the transactions contemplated thereby shall be paid by the party incurring
     such costs.  If the Merger is consummated, costs incurred by Infocore will
     ultimately be reflected in CEI's consolidated financial position.

          In the three following circumstances, Infocore has agreed to pay CEI a
     break-up fee of $100,000:  (i) CEI terminates the Merger Agreement due to a
     breach thereof by Infocore; (ii) Infocore terminates the Merger Agreement
     in order to enter into an Acquisition Transaction; and (iii) either CEI or
     Infocore terminates the Merger Agreement because the required approval of
     Infocore's shareholders has not been obtained.

          CEI has agreed to pay Infocore a break-up fee in the amount of
     $100,000 if the Merger Agreement is terminated by Infocore due to a breach
     thereof by CEI.

          Conversion of Infocore Shares

          On the Effective Date, all outstanding Infocore Common Shares shall in
     the aggregate be converted into 200,000 CEI Common Shares except for
     fractional shares and Dissenter's shares.

          Shares of Infocore Common Stock which are outstanding immediately
     prior to the Effective Date and which are held by shareholders who have
     delivered to Infocore a timely written objection to the Plan of Merger and
     who have not voted such shares in favor of the Merger ("Objecting Shares")
     shall not be converted into

                                      -28-
<PAGE>
 
     shares of CEI Common Stock, but instead, the holders thereof shall be
     entitled only to such dissenters' rights as are granted by the applicable
     Pennsylvania law; provided, however, that if any holder of Objecting Shares
     shall withdraw, lose, or forfeit his or her rights as a dissenting
     shareholder under applicable Pennsylvania law, such Objecting Shares shall
     thereupon be converted into CEI Common Stock in accordance with the terms
     of the Plan of Merger.  For a description of the Infocore shareholder
     action required to perfect dissenters' rights, see "Terms of the Merger--
     Dissenters' Rights."

          No Fractional Shares

          Neither fractional shares of CEI Common Stock nor script certificates
     thereof will be issued in connection with the Merger, but in lieu thereof
     each holder of shares of Infocore Common Stock otherwise entitled to a
     fraction of a share of CEI Common Stock will be paid in cash an amount
     equal to such fraction multiplied by an amount equal the average of the
     last reported bid and ask prices per share of CEI Common Stock for the
     Effective Date, as reported on the Nasdaq Quoted System.  No such holder
     will be entitled to dividends, voting rights or other rights in respect of
     any such fractional shares.

          Delivery of Shares

          As soon as practicable after the Effective Date, each Infocore
     shareholder will be mailed instructions, a form letter of transmittal and
     any materials to be used to surrender certificates representing Infocore
     Common Stock in exchange for certificates representing the CEI Common Stock
     (and cash in lieu of fractional shares) which such holder is entitled to
     receive pursuant to the Plan of Merger.  All certificates so surrendered
     will be cancelled.

          Dividends or other distributions on CEI Common Stock which are
     declared or made after the Effective Date will be withheld with respect to
     shares of CEI Common Stock issued pursuant to the Merger until the
     certificates for the Infocore Common Stock which were converted into said
     shares of CEI Common Stock have been surrendered and replaced with CEI
     Common Stock certificates.  Dividends or other distributions so withheld
     will not bear interest.

          No transfer taxes will be payable by Infocore shareholders in
     connection with the exchange of certificates representing Infocore Common
     Stock for certificates representing CEI Common Stock, except that, if any
     certificate is to be issued in the name other than that in which the
     certificate of Infocore common stock surrendered in exchange therefor is
     registered, it will be a condition of such exchange that the person
     requesting such exchange pay CEI any transfer or other taxes required in
     connection therewith or satisfy CEI that such tax has been paid or is not
     applicable.

          INFOCORE SHAREHOLDERS SHOULD NOT SURRENDER THEIR INFOCORE COMMON STOCK
     CERTIFICATES FOR EXCHANGE UNTIL THEY HAVE RECEIVED INSTRUCTIONS AND OTHER
     MATERIALS.  HOWEVER, INFOCORE SHAREHOLDERS ARE URGED TO NOTIFY INFOCORE NOW
     AT (610) 337-9611, IF THEIR CERTIFICATES ARE LOST, STOLEN OR DESTROYED, IN
     ORDER TO BEGIN THE PROCESS OF ISSUANCE OF REPLACEMENT CERTIFICATES.

     Interest of Certain Persons in the Merger

          Certain directors and officers of Infocore have interests in the
     Merger that are in addition to their interests as shareholders of Infocore
     generally.  These include CEI's agreement to employ Harrison H. Clement,
     Jr., President and Chief Executive Officer of Infocore and Henry M.
     Stringer, Senior Vice President of Infocore for two years after the
     Effective Date under the terms of the employment agreements.  See "THE
     MERGER--Terms of the Merger--Employment Agreements."

     Accounting Treatment

          The Merger will be treated as a purchase of Infocore by CEI for
     accounting and financial reporting purposes.  Under the purchase method of
     accounting, the assets and liabilities of Infocore will be recorded on the
     consolidated books of CEI at their fair values at the Effective Time.  The
     excess of the value of the consideration paid by CEI over the fair value of
     the assets and liabilities acquired will be treated as goodwill and will be
     amortized over a period not to exceed ten years.

     Certain Federal Income Tax Consequences

          The following is a summary of the anticipated material federal income
     tax consequences of the Merger.  Each shareholder's individual
     circumstances may affect the tax consequences of the Merger to that
     shareholder.  In addition, no information is provided herein with respect
     to the tax consequences of the Merger under applicable foreign, state or
     local laws.  Consequently, each Infocore shareholder is advised to consult
     his own tax advisor as to the specific tax consequences of the Merger.

          It is intended that the Merger will be treated for federal income tax
     purposes as a reorganization within the meaning of Section 368(a) of the
     Internal Revenue Code of 1986, as amended (the "Code"), and that,
     accordingly, for federal income tax purposes: (i) Infocore, Merger Sub and
     CEI will each be a "party to a reorganization" within the meaning of
     Section 368(b) of the Code; (ii) no gain or loss will be recognized by
     Infocore or CEI by reason of the Merger; (iii) except for any cash received
     in lieu of any fractional shares, no gain or loss will be recognized by
     holders of Infocore Common Shares who, pursuant to the Merger, receive
     solely CEI Common Shares in exchange for their Infocore Common Shares, (iv)
     the basis of the CEI Common Shares to be received by an Infocore
     shareholder will generally be the same as the basis of the Infocore Common
     Shares surrendered in exchange therefor, less any basis attributable to any
     fractional shares for which cash is received; and (v) the holding period of
     the CEI Common Shares to be received by a shareholder of Infocore will
     include the period during which the Infocore Common Shares surrendered in
     exchange therefor were held, provided that the Infocore Common Shares
     surrendered were held as a capital asset on the date of the exchange
     pursuant to the Merger.

          Infocore's obligation to consummate the Merger is conditioned upon
     receipt of an opinion of Saul, Ewing, Remick & Saul, tax counsel to
     Infocore, substantially to the effect that the federal income tax
     consequences of the Merger are as summarized above. Such an opinion of
     Saul, Ewing, Remick & Saul is attached to this Proxy Statement/Prospectus
     as Appendix D.

          Assuming that the Merger satisfies all of the requirements of a
     reorganization within the meaning of Section 368(a) of the Code, the Merger
     will have the following tax consequences to an Infocore shareholder who
     held Infocore Common Shares as a capital asset and will hold the CEI Common
     Shares received in exchange therefor as a capital asset.

          CEI Common Shares Received

          No gain or loss will be recognized by an Infocore shareholder upon the
     receipt of CEI Common Shares in exchange for Infocore Common Shares. The
     tax basis of the CEI Common Shares received by an Infocore shareholder in
     the Merger will equal the tax basis of the Infocore Common Shares
     surrendered in exchange therefor and, provided that such Infocore Common
     Shares were held as a capital asset as of the Effective Date, the holding
     period of the CEI Common Shares received by the shareholder will include
     the holding period for such Infocore Common Shares. An Infocore shareholder
     who receives cash in lieu of a fractional share of CEI Common Stock will
     generally recognize gain or loss to the extent that the cash received is
     more, or less than, the shareholder's tax basis in such fractional share.

          Dividends on CEI Shares

          Distributions of cash or other property received by holders of CEI
     Common Shares will be taxable dividends taxed at ordinary income tax rates
     to the extent of the earnings and profits of CEI.  Corporate holders,

                                      -30-
<PAGE>
 
     however, may be entitled to a dividends received deduction under Section
     243 of the Code (a 70 percent deduction is provided for corporate
     recipients which own less than 20 percent of CEI).

          Sale of CEI Common Shares

          A sale of CEI Common Shares received in the Merger will result in the
     recognition of capital gain or loss to the seller (provided the CEI Common
     Shares were held as a capital asset at the time of the sale).  Gain or loss
     will be computed by determining the difference between the sales price
     realized by the holder and such holder's basis in the shares sold.

          EACH INFOCORE SHAREHOLDER IS ENCOURAGED TO CONSULT HIS OR HER OWN TAX
     ADVISOR AS TO PARTICULAR FACTS AND CIRCUMSTANCES WHICH MAY BE UNIQUE TO
     SUCH SHAREHOLDER AND NOT COMMON TO SHAREHOLDERS AS A WHOLE AND ALSO AS TO
     ANY ESTATE, GIFT, STATE, LOCAL OR FOREIGN TAX CONSEQUENCES ARISING OUT OF
     THE MERGER AND/OR ANY SALE THEREAFTER OF CEI COMMON SHARES RECEIVED IN THE
     MERGER.

     Dissenters' Rights

          General

          Pursuant to the PBCL, any holder of Infocore Common Shares has the
     right to dissent from the Merger and to obtain payment of the "fair value"
     (as defined therein) of such holder's Infocore Common Shares, in the event
     that the Merger is consummated.  CEI shareholders will not have dissenters'
     rights in connection with the Merger.

          Any shareholder of Infocore who contemplates exercising a holder's
     right to dissent is urged to read carefully the provisions of Subchapter D
     of Chapter 15 of the PBCL attached to this Proxy Statement/Prospectus as
     Appendix B.  The following is a summary of the steps to be taken if the
     right to dissent is to be exercised, and should be read in connection with
     the full text Subchapter D of Chapter 15 of the PBCL.  Each step must be
     taken in the indicated order and in strict compliance with the applicable
     provisions of the statute in order to perfect dissenters' rights.  The
     failure of any holder of Infocore Common Shares to comply with the
     aforesaid steps will result in the holder receiving the consideration
     contemplated by the Merger Agreement in the event that the Merger is
     consummated.  See "THE MERGER--Terms of the Merger--Merger Consideration."

          Any written notice or demand which is required in connection with the
     exercise of dissenters' rights, whether before or after the Effective Time,
     must be sent to Infocore, Inc. at 661 Moore Road, Suite 110, King of
     Prussia, PA 19406, Attention: Secretary.

          Pursuant to the Merger Agreement, CEI is not obligated to consummate
     the Merger if holders of more than 10% of the outstanding Infocore Common
     Shares exercise dissenters' rights.

          Fair Value

          The term "fair value" means the value of an Infocore Common Share
     immediately before consummation of the Merger taking into account all
     relevant factors, but excluding any appreciation or depreciation in
     anticipation of the Merger.

          Notice of Intention to Dissent

          An Infocore shareholder who wishes to dissent must file with Infocore,
     prior to the vote of shareholders on the Merger at the Infocore Meeting, a
     written notice of intention to demand payment of the fair value of such
     holder's Infocore Common Shares if the Merger is effected, must effect no
     change in the beneficial ownership of his Infocore Common Shares from the
     date of such notice through the Effective Time, and must refrain from

                                      -31-
<PAGE>
 
     voting his Infocore Common Shares for approval of the Merger Agreement.
     Neither a proxy nor a vote against approval of the Merger will constitute
     the necessary written notice of intention to dissent.

          Notice to Demand Payment

          If the Merger Agreement is approved by the required vote of holders of
     Infocore Common Shares, Infocore will mail a notice to all dissenters who
     gave due notice of intention to demand payment and who refrained from
     voting for approval of the Merger Agreement.  The notice will state where
     and when a written demand for payment must be sent and certificates for
     Infocore Common Shares must be deposited in order to obtain payment, and
     will include a form for demanding payment and a copy of Subchapter D of
     Chapter 15 of the PBCL.  The time set for receipt of the demand for payment
     and deposit of stock certificates will be not less than 30 days from the
     date of mailing of the notice.

          Failure to Comply with Notice to Demand Payment, etc.

          A holder of Infocore Common Shares who fails timely to demand payment
     or fails timely to deposit his Infocore share certificates, as required by
     Infocore's notice, will forfeit his dissenters' rights and will receive CEI
     Common Shares plus cash for fractional shares in exchange for his Infocore
     Common Shares.

          Payment of Fair Value of Shares

          Promptly after the Effective Time, or upon timely receipt of demand
     for payment if the Merger already has been consummated, Infocore will
     either remit to dissenters who have made demand and have deposited their
     stock certificates the amount that Infocore estimates to be the fair value
     of the Infocore Common Shares or give written notice that no such
     remittance is being made.  The remittance or notice will be accompanied by
     (i) a closing balance sheet and statement of income of Infocore for a
     fiscal year ending not more than 16 months before the date of remittance or
     notice together with the latest available interim financial statements;
     (ii) a statement of Infocore's estimate of the fair value of the Infocore
     Common Shares; and (iii) a notice of the right of the dissenter to demand
     supplemental payment under the PBCL accompanied by a copy of Subchapter D
     of Chapter 15 of the PBCL.

          Estimate by Dissenter of Fair Value of Shares

          If a dissenter believes that the amount stated or remitted by Infocore
     is less than the fair value of the Infocore Common Shares, a dissenter may
     send to Infocore his own estimate of the fair value of the Infocore Common
     Shares, which shall be deemed to be a demand for payment of the amount of
     the deficiency.  If Infocore remits payment of its estimated value of a
     dissenter's Infocore Common Shares and the dissenter does not file his own
     estimate within 30 days after the mailing by Infocore of its remittance,
     the dissenter will be entitled to no more than the amount remitted to him
     by Infocore.

          Valuation Proceedings

          If any demands for payment remain unsettled, within 60 days after the
     latest to occur of (i) the Effective Date; (ii) timely receipt by Infocore
     of any demands for payment; or (iii) timely receipt by Infocore of any
     estimates by dissenters of fair value, Infocore may file in the Court of
     Common Pleas of Montgomery County (the "Court") an application requesting
     that the fair value of the Infocore Common Shares be determined by the
     Court. In such case, all dissenters, wherever residing, whose demands have
     not been settled, shall be made parties to the proceeding as in an action
     against their shares, and a copy of the application shall be served on each
     such dissenter.

          If Infocore were to fail to file such an application, then any
     dissenter, on behalf of all dissenters who have made a demand and who have
     not settled their claim against Infocore, may file an application in the
     name of Infocore at any time within the 30-day period after the expiration
     of the 60-day period and request that the fair value be determined by the
     Court.  The fair value determined by the Court may, but need not, equal the
     dissenters' estimates of fair value.  If no dissenter files such an
     application, then each dissenter entitled to do so

                                      -32-
<PAGE>
 
     shall be paid Infocore's estimate of the fair value of the Infocore Common
     Shares and no more, and may bring an action to recover any amount not
     previously remitted, plus interest at a rate the Court finds fair and
     equitable.

          Infocore intends to negotiate in good faith with any dissenting
     shareholders.  If after negotiation a claim cannot be settled, then
     Infocore intends to file an application requesting that the fair value of
     the Infocore Common Shares be determined by the Court.

          Costs and Expenses

          The costs and expenses of any valuation proceedings in the Court,
     including the reasonable compensation and expenses of any appraiser
     appointed by the Court to recommend a decision on the issue of fair value,
     will be determined by the Court and assessed against Infocore except that
     any part of the costs and expenses may be apportioned and assessed by the
     Court against all or any of the dissenters who are parties and whose action
     in demanding supplemental payment the Court finds to be dilatory, obdurate,
     arbitrary, vexatious or in bad faith.


                              RESALE RESTRICTIONS


          The CEI Common Shares issuable in connection with the Merger have been
     registered under the Securities Act, but such registration does not cover
     resales by shareholders of Infocore who may be deemed to control, be
     controlled by or be under common control with Infocore or CEI at the time
     of or after the Merger and who therefore may be deemed "affiliates" of
     Infocore or CEI as that term is used in Rule 145 under the Securities Act.
     Such affiliates may not sell the CEI Common Shares acquired in connection
     with the Merger except pursuant to:  (i) an effective registration
     statement under the Securities Act covering such shares; (ii) the
     conditions contemplated by paragraph (d) of Rule 145; or (iii) another
     applicable exemption from the registration requirements of the Securities
     Act.  Rule 145, as currently in effect, imposes restrictions on the manner
     in which such affiliates may make resales and also on the quantities of
     resales which such affiliates, and others with whom they act in concert,
     may make within any three-month period.

          The Merger Agreement requires as a condition to the Merger that each
     such affiliate of Infocore enter into an agreement not to sell CEI Common
     Shares acquired in the Merger except in accordance with the requirements of
     the Securities Act and the regulations thereunder.

          Persons who may be deemed to be affiliates of Infocore include
     directors, officers and certain large holders of Infocore Common Shares.
     Management of Infocore will notify those persons whom it believes may be
     such affiliates.  Infocore shareholders who are not deemed to be affiliates
     of Infocore or CEI may sell their CEI Common Shares without being subject
     to the above restrictions.


                      DESCRIPTION OF CAPITAL STOCK OF CEI

          As of March 14, 1997, CEI's authorized capital stock consisted of
     10,000,000 CEI Common Shares, par value $5.00 per share, 4,477,227 shares
     of which were issued and outstanding, and 900,000 CEI $3.42 Series A
     Preferred Shares, 196,618 shares of which were issued and outstanding.

     CEI Common Shares

          The following description of the CEI Common Shares is not intended to
     be complete and is qualified in its entirety by reference to CEI's
     Articles, a copy of which is on file with the Commission.

       Voting Rights

       Generally, with respect to all matters upon which shareholders are
entitled to vote (including the election of directors) or to which shareholders
are entitled to give consent, the holders of the outstanding CEI Common Shares
shall be entitled to cast one vote for each CEI Common Share held, provided that
each shareholder has cumulative voting rights in all elections for directors,
which is the right to cast as many votes in the aggregate as shall equal the
number of shares held by him or her multiplied by the number of directors to be
elected, and each shareholder may cast a whole number of votes for one candidate
or distribute such votes among two or more candidates.

       Ranking

       The CEI Common Shares rank, with respect to the payment of dividends
or distribution of assets upon liquidation, junior to the CEI $3.42 Series A
Preferred Shares.

       Dividends and Distributions

       The CEI Common Shares shall receive such dividends as are from time to
time declared by the CEI Board, subject to the prior payment of the dividends
due on the CEI $3.42 Series A Preferred Shares.

       In the case of dividends or other distributions payable in stock or
stock split-ups or divisions, shares of the CEI Common Shares shall be
distributed only with respect to CEI Common Shares.

       Liquidation Rights

       In the event of dissolution, liquidation or winding up of CEI, whether
voluntary or involuntary, holders of the CEI Common Shares shall be entitled to
payment out of the assets of CEI ratably in accordance with the number of shares
held by them, respectively, subject to the prior liquidation rights of the CEI
$3.42 Series A Preferred Shares.

       General

       CEI serves as the transfer agent and registrar for CEI Common Shares.

CEI $3.42 Series A Preferred Shares

       The following description of the material terms of the CEI $3.42
Series A Preferred Shares is not intended to be complete, and is qualified in
its entirety by reference to CEI's Articles, a copy of which is on file with the
Commission.

       The CEI $3.42 Series A Preferred Shares were issued to some of the
shareholders of Buffalo Valley Telephone Company (BVT) as a form of payment for
CEI's acquisition of BVT.

       Rank

       The CEI $3.42 Series A Preferred Shares rank, with respect to the
payment of dividends or distribution of assets upon liquidation, senior to CEI's
Common Shares, or any other class or series of CEI stock expressly stated to
rank junior to the CEI $3.42 Series A Preferred Shares ("Junior Stock"). The CEI
$3.42 Series A Preferred Shares rank pari passu with any other class or series
of CEI Stock expressly stated to be on a parity with the CEI $3.42 Series A
Preferred Shares ("Parity Stock"). As discussed below under "--Voting Rights",
CEI may not issue any stock ranking senior to the CEI $3.42 Series A Preferred
Shares ("Senior Stock") without the consent of the holders, voting together as a
single class, of the CEI $3.42 Series A Preferred Shares and any outstanding
Parity Stock.

                                      -34-
<PAGE>
 
       Dividends

       Holders of the CEI $3.42 Series A Preferred Shares are entitled to
receive, as and if declared by the CEI Board out of CEI funds legally available
therefor, cash dividends at an annual rate of $3.42 per share. Dividends are
paid in equal semi-annual installments of $1.71 and are cumulative. No interest
is payable in respect of any dividend payments which may be in arrears. So long
as CEI has funds legally available for such purpose, the CEI Board has a
mandatory duty to declare and pay dividends on the CEI $3.42 Series A Preferred
Shares (as well as to make required redemptions of CEI $3.42 Series A Preferred
Shares), and holders shall have the right to specifically enforce declaration
and payment of dividends (as well as required redemptions) to the extent
permitted by Section 1521(b) of the PBCL.

       Unless full cumulative dividends on outstanding CEI $3.42 Series A
Preferred Shares have been paid, no dividend or other distribution (except in
Junior Stock) shall be declared or paid on any Junior Stock and no amount shall
be set aside or applied to the redemption, purchase or other acquisition of
Junior Stock other than by exchange therefor of Junior Stock or, with respect to
redemptions, purchases or other acquisitions of Junior Stock other than CEI
Common Shares, out of the proceeds of a substantially concurrent sale of shares
of Junior Stock.

       Liquidation Rights

       In the event of any liquidation, dissolution or winding up of CEI, the
holders of CEI $3.42 Series A Preferred Shares shall be entitled to receive from
the assets of CEI payment in cash of $65 per share, plus a further amount equal
to unpaid cumulative dividends on CEI $3.42 Series A Preferred Shares accrued to
the date of payment, before any amount shall be paid or set aside for, or any
distribution of assets shall be made to, the holders of Junior Stock. If upon
any such liquidation, dissolution or winding up, the amounts payable with
respect to the holders of CEI $3.42 Series A Preferred Shares and any other
outstanding Parity Stock cannot be paid in full, then the holders of CEI $3.42
Series A Preferred Shares and such Parity Stock will share ratably in any such
distribution in proportion to the full respective preferential amounts
(including unpaid cumulative dividends, if any) to which they are entitled. None
of the following transactions will be considered a liquidation, dissolution or
winding up of CEI for these purposes: (i) a merger or consolidation of CEI with
any other corporation; (ii) a reorganization or division of CEI; (iii) the
purchase or redemption of all or part of any outstanding CEI stock; (iv) a sale
or transfer of all or any part of CEI's assets; or (v) a share exchange to which
CEI is a party.

       Conversion Rights

       The CEI $3.42 Series A Preferred Shares are convertible at the option
of the holder at any time into a number of whole shares of CEI Common Stock
equal to the liquidation preference of $65 divided by the conversion price in
effect at the time of such conversion (with fractional shares paid in cash as
described below). The right to convert CEI $3.42 Series A Preferred Shares which
have been called for redemption by CEI will terminate at the close of business
on the business day next preceding the redemption date unless CEI shall default
in paying the redemption price. See "--Redemption at the Option of CEI" below.

       The conversion price of the currently issued and outstanding CEI $3.42
Series A Preferred Shares is $34.425.

       The conversion price is subject to adjustment in certain events,
including: (i) dividends and other distributions on CEI Common Shares payable in
shares of any class or series of CEI capital stock; (ii) certain subdivisions,
combinations and reclassifications of CEI Common Shares; (iii) the issuance to
all holders of CEI Common Shares of rights, options or warrants entitling them
to subscribe for or purchase CEI Common Shares at less than the current market
price (as defined); and (iv) distributions to all holders of CEI Common Shares
of evidences of indebtedness of CEI or assets (excluding cash dividends) or
rights or warrants (other than the rights or warrants described in clause (iii)
above) to purchase or subscribe for any CEI securities.

                                      -35-
<PAGE>
 
       In the event of any (i) capital reorganization of CEI; (ii) merger,
consolidation or share exchange of CEI with or into another corporation; (iii)
division of CEI; or (iv) sale, lease, exchange or other disposition of all or
substantially all of the property and assets of CEI as a result of which other
than solely cash shall be exchanged for CEI Common Shares, all holders of CEI
$3.42 Series A Preferred Shares will thereafter have the right to convert CEI
$3.42 Series A Preferred Shares into the kind and amount of securities, stock or
other assets which the holders would have been entitled to receive upon such
reorganization, merger, consolidation, share exchange, division, sale, lease,
exchange or other disposition if the holders had held the number of CEI Common
Shares issuable upon conversion of their CEI $3.42 Series A Preferred Shares
immediately prior to such reorganization, merger, consolidation, share exchange,
division, sale, lease, exchange or other disposition.

       No adjustment of the conversion price will be required to be made
until cumulative adjustments amount to 1% or more of the conversion price as
last adjusted, except that any adjustments which are not required to be made
shall be carried forward and taken into account in calculating each subsequent
adjustment.
 
       Upon conversion of any CEI $3.42 Series A Preferred Shares, CEI shall
deliver to the holder of the shares, together with the certificates for the CEI
Common Shares issued upon conversion, payment for all accrued and unpaid
cumulative dividends on such shares through the date of conversion.

       Fractional CEI Common Shares will not be issued upon conversion.  In
lieu thereof, CEI will either pay a cash adjustment based upon market price of
CEI Common Shares on the business day preceding the date of conversion or
deliver a scrip certificate of CEI in respect of such fractional share.

       CEI will reserve a number of CEI Common Shares sufficient for the
satisfaction of any scrip certificates and the conversion of all outstanding CEI
$3.42 Series A Preferred Shares. For so long as CEI Common Shares are listed or
included for quotation or trading on any securities exchange or market or
trading system, CEI will list or include on any such exchange, market or system
all CEI Common Shares issuable upon conversion of the outstanding CEI $3.42
Series A Preferred Shares.

       Redemption at the Option of CEI

       The CEI $3.42 Series A Preferred Shares are not subject to any mandatory 
redemption or sinking fund provision. Commencing on May 31, 2000, the fourth
anniversary of the Closing Date of CEI's acquisition of BVT, the CEI $3.42
Series A Preferred Shares issued in such transaction will be redeemable for
cash, at the option of CEI, on at least 30 but not more than 60 days notice, in
whole or in part from time to time. The redemption price shall equal the
applicable percentage of $65 per share specified below, plus an amount equal to
the accrued and unpaid cumulative dividends to the redemption date:

holders have been made, CEI may not redeem any CEI $3.42 Series A Preferred
Shares or shares of Parity Stock unless all outstanding CEI $3.42 Series A

are redeemed, and CEI may not purchase or otherwise acquire any CEI $3.42 Series
A Preferred Shares or shares of Parity Stock except in accordance with a
purchase or exchange offer made simultaneously to all holders of CEI $3.42
Series A Preferred Shares and shares of Parity Stock which, in the reasonable
opinion of the CEI Board, will result in fair and equitable treatment among all
such shares. If less than all of the outstanding CEI $3.42 Series A Preferred
Shares shall be called for redemption, the particular shares to be redeemed
shall be selected by lot or by such other equitable manner as may be prescribed
by the CEI Board.

       Redemption at the Option of the Holders

       Commencing on May 30, 1998, the second anniversary of the Closing Date of
CEI's acquisition of BVT and at any time or from time to time thereafter, each
holder of CEI $3.42 Series A Preferred Shares issued in such transaction shall
have the right, at such holder's option, to require CEI to redeem all or a
portion of such holder's CEI $3.42 Series A Preferred Shares at a redemption
price of $65, plus an amount equal to the accrued and unpaid cumulative
dividends thereon to the redemption date. Requests for redemption by holders of
CEI $3.42 Series A Preferred Shares will be irrevocable and (unless CEI shall
default in making the requested redemption) shall terminate all conversion
rights of the holder with respect to the CEI $3.42 Series A Preferred Shares to
be redeemed.

       Holders may not exercise their optional redemption right for less than
100 shares of CEI $3.42 Series A Preferred Shares (or, if less than 100, all
shares of CEI $3.42 Series A Preferred Shares owned by such holder). As of each
March 31, June 30, September 30 and December 31, CEI shall redeem all CEI $3.42
Series A Preferred Shares for which a notice of optional redemption has been
received by CEI prior to the close of business on the immediately preceding
February 15, May 15, August 15 or November 15, respectively. CEI shall also
redeem all CEI $3.42 Series A Preferred Shares for which a notice of optional
redemption has been received by CEI during the 30 day period following the date
of mailing by CEI to the holders of a notice of a reclassification, capital
reorganization, merger, consolidation, share exchange, division, sale, lease,
exchange or other disposition of assets, liquidation, dissolution or winding-up
relating to CEI.

       Voting Rights

       Except as indicated below or as required by law, holders of CEI $3.42
Series A Preferred Shares will have no voting rights. In the event that (i)
dividends upon the CEI $3.42 Series A Preferred Shares shall be in arrears in an
amount equal to three full semi-annual dividends thereon or (ii) any redemption
of CEI $3.42 Series A Preferred Shares at the option of the holder has not been
made as required, the number of directors constituting the full CEI Board shall
be increased by two, and the holders of the CEI $3.42 Series A Preferred Shares,
voting noncumulatively separately as a single class together with the holders of
any other shares of CEI preferred stock having similar voting rights then
exercisable, shall be entitled to elect two additional members of the CEI Board
until all accumulated and unpaid dividends have been paid and all required
redemptions have been made.

       Without the affirmative vote of the holders of at least a majority of the
CEI $3.42 Series A Preferred Shares, CEI may not amend, alter, change or repeal
any of the express terms of the CEI $3.42 Series A Preferred Shares.

       In addition, without the affirmative vote of the holders of at least a
majority of the CEI $3.42 Series A Preferred Shares then outstanding or, if
holders of other series of CEI preferred stock have the right to vote as a class
on such matter under CEI's Articles, the holders of at least a majority of CEI
$3.42 Series A Preferred Shares and other series of CEI preferred stock voting
as a single class, CEI shall not (i) authorize or permit any shares of Senior
Stock to be outstanding; (ii) increase the authorized number of shares of Senior
Stock; or (iii) merge, consolidate, divide or participate in a share exchange
with any other corporation if the corporation surviving or resulting from such
transaction would have outstanding shares of Senior Stock in excess of the
number of shares of Senior Stock of CEI permitted to be outstanding immediately
prior to such merger, consolidation, division or share exchange.

                                      -37-
<PAGE>
 
       When holders of CEI $3.42 Series A Preferred Shares have the right to
vote as described above, each holder of a CEI Series A Preferred Share shall be
entitled to one vote or fraction thereof, for each $10.00 or fraction thereof,
of the $65 liquidation preference represented by such CEI Series A Preferred
Share.

       No Trading Market

       The CEI $3.42 Series A Preferred Shares is not listed on Nasdaq or any
securities exchange. An active public trading market for the CEI $3.42 Series A
Preferred Shares has not developed since it was issued as part of the
acquisition of BVT.

       No Rating

        CEI has not applied for a rating of the CEI $3.42 Series A Preferred
Shares from Moody's, S&P or any other statistical rating organization.

        Miscellaneous

        CEI serves as the transfer agent, conversion agent and registrar for the
CEI $3.42 Series A Preferred Shares. Holders of CEI $3.42 Series A Preferred
Shares have no preemptive rights with respect to any shares of capital stock of
CEI or any other securities of CEI convertible into or carrying rights or
options to purchase any such shares.

        Pennsylvania Anti-Takeover Law Provisions

        CEI is subject to various statutory "anti-takeover" provisions of the
PBCL, including Subchapters 25E and F of the PBCL.

        Subchapter 25E (relating to control transactions) provides that if any
person or group acquires 20% or more of the voting power of a covered
corporation, the remaining shareholders may demand from such person or group the
fair value of their shares, including a proportionate amount of any control
premium. Subchapter 25F (relating to business combinations) delays for five
years and imposes conditions upon "business combinations" between an "interested
shareholder" and the corporation. The term "business combination" is defined
broadly to include various transactions utilizing a corporation's assets for
purchase price amortization or refinancing purposes. An "interested shareholder"
is defined generally as the beneficial owner of at least 20% of a corporation's
voting shares. Subchapters 25E and F contain a wide variety of transactional and
status exemptions, exclusions and safe harbors. The foregoing descriptions are
qualified in their entirety by reference to the applicable statutory provisions
incorporated herein by reference.

        The CEI Bylaws, however, render several other "anti-takeover" provisions
of the PBCL inapplicable to CEI, including Subchapters 25G (relating to control-
share acquisitions), 25H (relating to disgorgement), 25I (relating to certain
required severance payments) and 25J (relating to labor contracts), as well as a
standard of required director conduct giving directors broader discretion than
is permitted under the traditional rule of director conduct to consider the
interests of a wide range of groups affected by its decisions and to reject
proposed acquisitions or changes in control. The CEI Board of Directors has
adopted and is submitting to its shareholders for approval at CEI's Annual
Meeting of Shareholders scheduled for May 3, 1997, a by-law amendment which
makes applicable to CEI the aforementioned broader discretion for directors to
consider the interests of various interest groups and to reject proposed
acquisitions or changes in control.

        The PBCL permits an amendment of the corporation's articles or other
corporate action, if approved by shareholders generally, to provide mandatory
special treatment for specified groups of nonconsenting shareholders of the same
class by providing, for example, that shares of common stock held only by
designated shareholders of record, and no other shares of common stock, shall be
cashed out at a price determined by the corporation, subject to applicable
dissenters' rights.

                       COMPARISON OF SHAREHOLDER RIGHTS

Introduction

        Upon consummation of the Merger holders of Infocore Common Shares,
whose rights presently are governed by the PBCL and Infocore's Articles and
Bylaws, will become holders of CEI Common Shares. Accordingly, their rights will
be governed by the PBCL and CEI's Articles and Bylaws. Certain differences arise
from differences between the Infocore Articles and the Infocore Bylaws, on the
one hand, and the CEI Articles and CEI Bylaws, on the other hand, as well as
from differences in treatment under the PBCL in certain instances of publicly
traded or "registered" corporations, such as CEI, as compared to privately held
"non-registered" corporations, such as Infocore. The following discussion is not
intended to be a complete statement of all differences and is qualified in its
entirety by reference to applicable Pennsylvania corporate laws and the Articles
and Bylaws of Infocore and CEI. See "INCORPORATION OF DOCUMENTS BY REFERENCE"
and "AVAILABLE INFORMATION."

Dividends

        Holders of Infocore Common Shares are entitled to receive such
dividends as may be declared by the Infocore Board from time to time. Infocore
has never paid a cash dividend on the common shares.

        Holders of CEI $3.42 Series A Preferred Shares are entitled to
cumulative semi-annual cash dividends of $1.71 ($3.42 annually) per share. CEI
Preferred Shares have preference over CEI Common Shares as to dividends. See
"DESCRIPTION OF CAPITAL STOCK OF CEI--CEI $3.42 Series A Preferred Shares."
 
        Holders of CEI Common Shares are entitled to receive such dividends as 
may be declared by the CEI Board from time to time. CEI and its predecessor
publicly held corporation, CTT, have maintained a policy of paying cash
dividends since 1909, and CEI does not intend to alter this policy in the
foreseeable future. During 1996 CEI has paid dividends on the CEI Common Shares
at the annual rate of $1.20 per share. If all of the outstanding options to 
acquire 921,731 Infocore Common Shares are exercised with the result that 
6,700,687 Infocore Common Shares are issued and outstanding on the Closing Date,
the Common Stock Exchange Ratio will be .0298477 CEI Common Share for each 
Infocore Common Share. Consequently, Infocore shareholders will receive 2.98477 
CEI Common Shares for each 100 Infocore Common Shares and,  under CEI's current 
dividend policy, will receive annual dividends totalling $3.58 for each 100 
shares of Infocore common converted to CEI common. See "DESCRIPTION OF CAPITAL 
STOCK OF CEI -- CEI Common Shares."

Voting Rights Generally

        With respect to most matters on which shareholders are entitled
to vote, holders of Infocore Common Shares are entitled to one vote per share.
Holders of Infocore Common Shares are not entitled to cumulate their votes for
the election of directors. Any action to be taken by vote of the Infocore
shareholders shall be authorized upon the affirmative vote of a majority of the
Infocore Common Shares represented and entitled to vote at a shareholders
meeting.

        Except as required by law or as described below, holders of CEI $3.42 
Series A Preferred Shares have no voting rights. If CEI fails to pay dividends
in an amount equal to three full semi-annual dividends or fails to redeem CEI
$3.42 Series A Preferred Shares when required, holders of CEI $3.42 Series A
Preferred Shares, voting as a class together with any other CEI preferred
shareholders having a similar right,will be entitled to elect two directors to
the CEI Board. Holders of CEI $3.42 Series A Preferred Shares also have voting
rights in limited circumstances where CEI desires to take specified corporate
actions that may be adverse to the rights and preferences of the CEI $3.42
Series A Preferred Shares. Where any such voting rights apply, each CEI
Preferred Share shall have one vote (or fraction thereof) for each $10 (or
fraction thereof) of liquidation preference of such shares. See "DESCRIPTION OF
CAPITAL STOCK OF CEI--CEI $3.42 Series A Preferred Shares."

        With respect to all matters on which shareholders are entitled to vote 
(excluding the election of directors), CEI Common Shares are entitled to one
vote per share. Holders of CEI common Shares are entitled to cumulate their
votes for the election of directors. See "DESCRIPTION OF CAPITAL STOCK OF CEI--
CEI Common Shares." Except for the election of directors, in general, any action
to be taken by vote of the CEI

                                      -39-
<PAGE>
 
shareholders shall be authorized upon the affirmative vote of a majority of the 
votes cast at a shareholders meeting.

Classified Board of Directors

        The PBCL permits a corporation's Board of Directors to be divided into 
various classes serving staggering terms of office. The CEI Bylaws provide that
the CEI Board be divided into three classes of directors of three directors
each. At each annual meeting of shareholders, one class of directors is elected
to serve for a three-year term. Classification of directors has the effect of
making it more difficult for shareholders to change the composition of the Board
of Directors. At least two annual meetings of shareholders, instead of one, will
generally be required to effect a change in the majority of the Board of
Directors. Such classification provisions could have the effect of discouraging
a third party from initiating a proxy contest, making a tender offer or
otherwise attempting to obtain control of CEI.

        Infocore's Board is not classified.  Any shareholders seeking to elect 
its designees to a majority of the seats on the Infocore Board, therefore, could
do so at any annual meeting.

Number of Directors

        The Infocore Bylaws establish the number of directors as at least one 
and not more than eleven. The CEI Bylaws establish the number of directors at
nine.

Removal of Directors

        Infocore directors may be removed from office without cause by
shareholder vote. CEI directors may only be removed for cause by shareholder
vote. This removal restriction strengthens the anti-takeover effect of the
classified board provision in the CEI Bylaws.

Filling Vacancies on the Board of Directors

        The Infocore Bylaws provide that vacancies occurring on the Board of 
Directors may be filled by the affirmative vote of a majority of the remaining
directors, even if the number of remaining directors constitutes less than a
quorum. Any director so chosen shall serve for the balance of the unexpired
term.

        The CEI Bylaws provide that vacancies occurring on the Board of 
Directors may be filled by the affirmative vote of a majority of the remaining
directors, even if the number of remaining directors constitutes less than a
quorum. Any director so chosen shall have a term of office equal to the
unexpired portion of the term of the director whose place shall be vacant.

Call of Special Shareholders' Meeting

        Special meetings of the shareholders of Infocore may be called by (i) 
the board of directors, (ii) the chairman of the board or the president, or
(iii) at the request of the holders of not less than 20% of all the outstanding
shares of Infocore entitled to vote at such meeting. Special meetings of CEI's
shareholders may be called by (i) the president, (ii) the Board of Directors or
(iii) the president upon the written request of the holders of not less than 20%
of all outstanding shares of CEI entitled to vote at such meeting, provided such
request specifies the purpose of the meeting. No business other than that stated
in the notice of meeting may be acted upon at a CEI special shareholders'
meeting.

Notice of Shareholders' Meeting

        Notice of an Infocore shareholders' meeting must be delivered at least 
ten days prior to the day named for a meeting called to consider a fundamental
change under Chapter 19 of the PBCL or five days prior thereto in any other
case. Notice of a CEI shareholders' meeting must be given at least ten days
before the date of the meeting, unless a greater period of notice is required by
law in a particular case.

                                      -40-
<PAGE>
 
Quorum Requirements and Adjournment of Meetings

        The presence, in person or by proxy, of the holders of a majority of 
the outstanding shares entitled to vote at a meeting constitutes a quorum for an
Infocore and a CEI shareholders' meeting. A majority of the outstanding shares
represented at the meeting, even if less than a quorum, may adjourn an Infocore
or CEI shareholders' meeting from time to time. Notice of adjournment is not
required.

        Shareholders present at a duly convened Infocore shareholders'
meeting may continue to transact business until adjournment of the meeting,
notwithstanding the withdrawal of enough shareholders to leave less than a
quorum. In the case of an Infocore shareholders' meeting called for the election
of directors, such meeting may be adjourned for any period not exceeding 15
days; and those Infocore shareholders who attend a meeting which had previously
been adjourned shall, even if they are less than a quorum, constitute a quorum
for the purpose of electing directors, but for no other purpose.

        If a quorum is not present at a CEI shareholders' meeting, no
business may be transacted except to adjourn the meeting to a future time.

Action Without Meeting

        Infocore and CEI shareholders may take action only at a shareholders'
meeting or by unanimous written consent.

Dissenters' Rights

        Under the PBCL, shareholders are generally entitled to dissent
from, and demand payment of the fair value of their shares in connection with a
plan of merger, consolidation, share exchange, asset transfer or division. In
accordance with the PBCL, holders of Infocore Common Shares are entitled to
dissenters' rights in connection with the Merger. See "THE MERGER--Dissenters'
Rights."

        Dissenters' rights under the PBCL would be available to holders of CEI 
Common Shares in connection with a plan of merger, consolidation, share
exchange, asset transfer or division to which CEI is a party. CEI is not a party
to the Merger.

Limitations on Directors' Liability

        As permitted by the PBCL, both the Infocore and CEI Bylaws provide that 
directors shall not be personally liable to the corporation or its shareholders
for monetary damages for any action taken, or any failure to take any action,
unless the director has breached or failed to perform the duties of his or her
office under applicable Pennsylvania law and the breach or failure to perform
constitutes self-dealing, willful misconduct or recklessness. These provisions,
however, do not apply to the responsibility or liability of a director pursuant
to any criminal statute or the liability of a director for the payment of taxes
pursuant to local, state or federal law.

Indemnification

        Sections 1741 and 1742 of the PBCL generally provide that a corporation 
may indemnify directors and officers against liabilities they may incur in such
capacity provided that the particular person acted in good faith and in a manner
he or she reasonably believed to be in, or not opposed to, the best interests of
the corporation, and, with respect to any criminal proceeding, had no reasonable
cause to believe his or her conduct was unlawful. In the case of actions against
a director or officer by or in the right of the corporation, the power to
indemnify extends only to expenses (not judgments and amounts paid in
settlement) and such power generally does not exist if the person otherwise
entitled to indemnification shall have been adjudged to be liable to the
corporation unless it is judicially determined that, despite the adjudication of
liability but in view of all the circumstances of the case, the person is fairly
and reasonably entitled to indemnification for specified expenses. Section 1743
of the PBCL also requires a corporation to indemnify directors and officers
against expenses they

                                      -41-
<PAGE>
 
may incur in defending actions against them in such capacities if they are
successful on the merits or otherwise in the defense of such actions.

        Section 1746 of the PBCL also grants a corporation broad authority, 
beyond the power granted under Sections 1741 and 1742, to indemnify its
directors, officers and other agents for liabilities and expenses incurred in
such capacity, except in circumstances where the act or failure to act giving
rise to the claim for indemnification is determined by a court to have
constituted willful misconduct or recklessness. Pursuant to the authority of
Section 1746 of the PBCL, both the CEI and Infocore Bylaws provide for
indemnification of directors, officers and other agents of the corporation to
the extent otherwise permitted by Section 1741 of the PBCL and also in certain
circumstances not otherwise permitted by Sections 1741 and 1742 of the PBCL.

State Anti-Takeover Law Provisions

        The PBCL contains certain "anti-takeover" provisions that are only 
applicable to "registered" corporations. These provisions do not apply to
Infocore. Because CEI is a registered corporation, these provisions could be
applicable to CEI. See "DESCRIPTION OF CAPITAL STOCK OF CEI--Pennsylvania Anti-
Takeover Law Provisions."

        Subchapter 25E of the PBCL is a "cash-out" antitakeover statute
which generally provides that if any person or group acquires 20% or more of the
voting power of a corporation, the remaining shareholders may demand from such
person or group the fair value of their shares, including a proportionate amount
of any control premium.

        Under Subchapter 25F of the PBCL, CEI is prohibited from engaging in 
specified business combination transactions with an interested stockholder
(defined in general as any beneficial owner of at least 20% of CEI's outstanding
voting power) during the five-year period following the date such person became
an interested stockholder unless (i) the business combination or share
acquisition is approved by CEI's Board prior to the date such person becomes an
interested stockholder, (ii) the business combination is approved by unanimous
vote of the holders of all outstanding common stock, or (iii) the interested
shareholder owns at least 80% of CEI's outstanding voting power, the business
combination is approved by a majority of the holders of CEI voting shares (not
including shares held by the interested shareholder), and the interested
shareholder complies with specified procedural and minimum fair price criteria.
After the five-year period, a business combination may be effected if (i) the
transaction is approved by a majority of the outstanding CEI voting power (not
including shares held by the interested shareholder), or (ii) the transaction is
approved by a majority of the outstanding CEI voting power (including shares
held by the interested shareholder) and the interested shareholder complies with
specified procedural and minimum fair price criteria. CEI is also subject to
another Pennsylvania law provision (PBCL Section 2538) which requires certain
fundamental transactions with an interested shareholder to be approved by a
majority of the corporation's directors who are unaffiliated with such
shareholder.

Amendment of Articles of Incorporation

        Persons holding at least 10% of the Infocore Common Shares may propose 
amendments to the Infocore Articles. Because CEI is a registered corporation,
under the PBCL, CEI shareholders are not entitled to propose amendments to the
CEI Articles, and all amendments must first be approved by the CEI Board.

        Except for the general requirement that charter amendments affecting 
any particular class or series of stock be approved by the affected class or
series, proposed amendments to the Infocore and the CEI Articles require
shareholder approval by the affirmative vote of a majority of the votes cast by
all shareholders entitled to vote thereon. For a description of the amendments
to the CEI Articles requiring a separate class vote, see "DESCRIPTION OF CAPITAL
STOCK OF CEI--CEI $3.42 Series A Preferred Shares--Voting Rights."

Amendment of Bylaws

        The Infocore Bylaws may be amended by a majority vote of the 
shareholders entitled to vote thereon at any regular or special meeting duly
convened after notice to the shareholders for that purpose. In addition, the

                                      -42-
<PAGE>
 
Board of Directors may, by a majority vote, amend the Bylaws, subject to the
power of the shareholders to change such action, provided that the specific 
amendment does not relate to any subject that is committed expressly to the 
shareholders by any provision of the PBCL.

        The CEI Bylaws may be amended at any regular or special meeting of the 
CEI shareholders by a majority vote of all the shares represented and entitled
to vote at the meeting.

                              BUSINESS OF INFOCORE

Description of Business

        Infocore is a diversified regional communication services provider with
its executive offices located at 661 Moore Road, King of Prussia, Pennsylvania
19406, telephone number (610) 337-9611. As of December 31, 1996, Infocore had
approximately 542 customers.

        Founded in 1981, Infocore provides a broad array of premise equipment 
and network services, primarily to commercial markets throughout Southeastern
Pennsylvania. The sale and service of customer premise equipment, which includes
the sale and service of voice and data communications equipment, including
business telephone systems, local area networks and computer-telephone
integration, contributed approximately 53% of Infocore's revenues in 1996.
Infocore's resale of local and long distance services contributed approximately
47% of its 1996 revenues. In 1995, Infocore formed a wholly owned subsidiary,
Infocore Wireless ("IW"), to pursue ownership of PCS licenses. On March 9, 1995,
Conestoga Enterprises, Inc. and IW formed CWC, a Pennsylvania limited liability
company. On January 14, 1997, CWC was a successful bidder in the Federal
Communications Commission's PCS radio spectrum D, E and F Block Auction. CWC was
the high bidder for radio spectrum licenses in four basic trading areas:
Reading, Pottsville, Sunbury and Williamsport. These territories cover nine
Pennsylvania counties with a total population of approximately 840,000.

Security Ownership of Certain Beneficial Owners and Management of Infocore

        The following table sets forth as of April 7, 1997 certain information
regarding the beneficial ownership of Infocore Common Shares by (i) each
director and executive officer of Infocore, (ii) all directors and executive
officers of Infocore as a group, and (iii) each other person known by Infocore
to own beneficially more than 5% of the Infocore Common Shares .

                                 PLAN OF MERGER

               2.1  The Merger.  On the Effective Date Infocore shall be merged
                    ----------                                                 
     with and into Sub pursuant to this Agreement and the separate existence of
     Infocore shall cease.  Sub shall be the surviving corporation in the Merger
     (sometimes hereinafter referred to as the "Surviving Corporation"), and the
     separate corporate existence of Sub with all its rights, privileges,
     immunities, powers and franchises shall continue unaffected by the Merger.
     The Infocore 1991 Stock Option Plan shall be terminated as of the Effective
     Date.

               2.2  Conversion and Exchange of Shares.
                    --------------------------------- 

                    (a) CEI Common Stock.  The shares of CEI Common Stock issued

                        ----------------

     all of the issued and outstanding shares of the capital stock of the
     Surviving Corporation.

                    (c) Infocore Common Stock.  Upon the Effective Date, the 
                        ---------------------      
     shares of Infocore Common Stock issued and outstanding and held by any
     person, except for Dissenters' Shares, shall, by virtue of the Merger and
     without any action on the part of the holder thereof, become and be
     converted into that number of shares of CEI Common Stock as is equal to the
     number of shares of Infocore Common Stock held by such person multiplied by
     a fraction, the numerator of which is 200,000 and the denominator of which
     is the number of shares of Infocore Common Stock issued and outstanding
     immediately prior to the Effective Date.

               2.3  Timing.
                    ------ 

                    (a) Shareholder Approval.  Infocore shall submit this 
                        --------------------       
     Agreement to its shareholders for approval as provided in Section 5.5
     hereof. In connection with such meeting, Infocore and CEI shall each take,
     as promptly as practical, such reasonable steps as shall be necessary for
     the preparation and filing by CEI of a registration statement under the
     1933 Act on Form S-4 (the "Registration Statement") with the SEC and shall
     use its reasonable best efforts to cause the Registration Statement to
     become effective as soon as practicable.

                    (b) Closing and Effective Date.  The parties shall hold a 
                        --------------------------     
     closing (the "Closing") on a mutually agreeable date (the "Closing Date")
     no later than the fifth business day after the satisfaction or waiver of
     the conditions set forth in Article V and Article VI of this Agreement, at
     10:00 A.M., local time, at the offices of CEI, or at such other place or
     time as the parties agree upon. On the Closing Date or as soon thereafter
     as is practicable, the parties shall execute and file in the offices of the
     Corporation Bureau of the Commonwealth of Pennsylvania appropriate Articles
     of Merger in accordance with the provisions of the Corporation Law. The
     "Effective Date" shall be the date of filing the Articles of Merger.

               2.4  Dissenters' Rights.  The shares of Infocore Common Stock
                    ------------------                                      
     ("Dissenters' Shares") held by any shareholder of Infocore who has
     exercised dissenters' rights pursuant to the Corporation Law (a "Dissenting
     Shareholder") shall not be converted pursuant to this plan unless and until
     the holder thereof shall have failed to perfect or shall have effectively
     withdrawn or lost such holder's rights to dissent from the Merger under the
     Corporation Law, and shall be entitled to receive only the payment to the
     extent provided for by the Corporation Law.  If any such holder shall fail
     to perfect or shall have effectively withdrawn or lost the right to
     dissent, the Dissenters' Shares held by such Dissenting Shareholder shall
     thereupon be treated as though such shares had been converted into shares
     of CEI Common Stock pursuant to the terms hereof.

               2.5  Surrender and Exchange of Infocore Certificates.
                    -----------------------------------------------

                    (a) Delivery of Certificates.  As soon as feasible after the
                        ------------------------                                
     Effective Date, CEI will, upon surrender of all certificates for Infocore
     Common Stock ("Old Certificates") held by an Infocore shareholder,
     accompanied by a duly executed letter of transmittal in proper form (if
     required by CEI), issue and deliver to such Infocore shareholder a
     certificate representing the number of shares of CEI Common Stock to which
     such Infocore shareholder is entitled under the terms of the Merger, and a
     check for fractional shares as provided below.

                    (b) No Fractional Shares.  No certificates for fractional 
                        -------------------- 
     shares of CEI Common Stock shall be issued in connection with the Merger.
     In lieu thereof, CEI shall issue to any holder of Infocore Common Stock
     certificates otherwise entitled to a fractional share, upon surrender of
     such certificates as provided above, a check for an amount of cash equal to
     the fraction of a share represented by the certificates so surrendered
     multiplied by an amount equal to the sum of the average of the last
     reported bid and ask prices per share of CEI Common Stock for the Effective
     Date, as reported on the NASDAQ Quotation System.

                    (c) Dividends.  If any dividend on CEI Common Stock is 
                        ---------   
     declared after the Effective Date, the declaration shall include dividends
     on all shares of CEI Common Stock into which shares of Infocore Common
     Stock have been converted under this Agreement, but no former holder of
     Infocore Common Stock shall be entitled to receive payment of any such
     dividend until surrender of the shareholder's Old Certificates have been
     effected in accordance with the instructions furnished by CEI. Upon
     surrender for exchange of a shareholder's Old Certificates, such
     shareholder shall be entitled to receive from CEI an amount equal to all
     such dividends declared and for which the payment date has occurred,
     without interest thereon and less the amount of taxes, if any, which may
     have been imposed or paid thereon, on the shares of CEI Common Stock into
     which the shares represented by such Old Certificates have been converted.

                    (d) Closing of Stock Transfer Books.  After the Effective 
                        -------------------------------  
     Date, there shall be no transfer on the stock transfer books of Infocore or
     CEI of shares of Infocore Common Stock. If Old Certificates are presented
     for transfer after the Effective Date, they shall be cancelled and
     certificates representing shares of CEI Common Stock and cash for
     fractional shares shall be issued in exchange therefor as provided herein.

                    (e) Unclaimed Merger Consideration.  To the extent permitted
                        ------------------------------
     by law, in the event that any Old Certificates have not been surrendered
     for exchange in accordance with this Section on or before the second
     anniversary of the Effective Date, CEI may at any time thereafter, with or
     without notice to the holders of record of such Old Certificates, sell for
     the accounts of any or all of such holders any or all of the shares of CEI
     Common Stock which such holders are entitled to receive under Subsection
     (a) hereof (the "Unclaimed Shares"). Any such sale may be made by public or
     private sale or sales at any broker's board or on any securities exchange
     in such manner and at such times as CEI shall determine. If in the opinion
     of counsel for CEI it is necessary or desirable, any Unclaimed Shares may
     be registered for sale under the 1933 Act and applicable state laws. CEI
     shall not be obligated to make any sale of Unclaimed Shares if it shall
     determine not to do so, even if notice of sale of the Unclaimed Shares has
     been given. The net proceeds of any such sale of Unclaimed Shares shall be
     held for holders of the unsurrendered Old Certificates whose Unclaimed
     Shares have been sold, to be paid to them upon surrender of the Old
     Certificates. From and after any such sale, the sole right of the holders
     of the unsurrendered Old Certificates whose Unclaimed Shares have been sold
     shall be the right to collect the net sale proceeds held by CEI for their
     respective accounts, and such holders shall not be entitled to receive any
     interest on such net sale proceeds held by CEI.

                    (f) Escheat.  If outstanding certificates for shares of 
                        -------      
     Infocore Common Stock are not surrendered prior to the date on which such
     certificates would otherwise escheat to or become the property of any
     governmental unit or agency, the unclaimed items shall, to the extent
     permitted by abandoned property and any other applicable law, become the
     property of CEI (and to the extent not in its possession shall be paid over
     to it), free and clear of all claims or interest of any person previously
     entitled to such claims.  Notwithstanding the foregoing, neither CEI nor
     its agents or any other person shall be liable to any former holder of
     Infocore Common Stock for any property delivered to a public official
     pursuant to applicable abandoned property, escheat or similar laws.

                    (g) Lost or Stolen Certificates.  In the event any Old
                        ---------------------------                       
     Certificate shall have been lost, stolen or destroyed, upon the making of
     an affidavit of that fact by the person claiming such Old Certificate to be
     lost, stolen or destroyed and, if required by CEI, the posting by such
     person of a bond in such amount as CEI may

                                      -4-
<PAGE>
 
     direct as indemnity against any claim that may be made against it with
     respect to such Certificate, CEI will issue in exchange for such lost,
     stolen or destroyed Old Certificate, a certificate for that number of
     shares of CEI Common Stock into which such Old Certificates have been
     converted pursuant to this Agreement and cash for fractional shares as
     provided herein.

               2.6  Articles of Incorporation, By-laws, and Directors and
                    -----------------------------------------------------
     Officers of Sub.  The Articles of Incorporation and By-laws of Sub in
     ---------------                                                      
     effect immediately prior to the Merger shall remain in effect as the
     Articles of Incorporation and By-laws of the Surviving Corporation, except
     that Article I of the Articles of Incorporation of Sub shall be amended to
     read as follows:  "The name of the Corporation is Infocore, Inc."  The

     the directors of the Surviving Corporation.  Provided they have executed
     and delivered the employment agreements referred to in Section 6.3,

     Officer of the Surviving Corporation and Henry M. Stringer shall become the

     Subsidiaries, taken as a whole, which would constitute an Infocore Material
     Adverse Effect.

               3.10 Tax and Other Returns and Reports.  All federal, state,
                    ---------------------------------                      
     local and foreign tax returns, reports and statements required to be filed
     by Infocore or any Subsidiary have been filed within the time and in the
     manner prescribed by law.  Such returns correctly reflected the facts
     regarding the income, businesses, assets, operations and activities of
     Infocore and any Subsidiary.  Such returns correctly reflected all taxes
     due or payable by Infocore or any Subsidiary through the date of this
     Agreement.  Taxes shown to be due and payable thereon have been paid or
     adequately reserved, and there are no pending assessments, asserted
     deficiencies or claims for additional taxes which have not been paid.
     There are no material deficiencies which representatives of the IRS or any
     other taxing authority have advised Infocore are expected to be included in
     an audit report, and no material special charges, penalties, interest or
     fines are being asserted against Infocore or any of its Subsidiaries with
     respect to payment or failure to pay any taxes.  None of the federal tax
     returns filed by Infocore have been audited by the IRS.  In the opinion of
     Infocore's management, the reserve or accrual for taxes shown on the
     Infocore Balance Sheet is sufficient for payment of all unpaid federal,
     state, local and foreign taxes of Infocore and its Subsidiaries through
     such date.

               3.11 Dividends and Stock Purchases.  Since December 31, 1996
                    -----------------------------                          
     Infocore has not declared, set aside or paid any dividend, or made or
     agreed to make any other distribution or payment in respect of shares of
     Infocore's capital stock nor has it redeemed, purchased or otherwise
     acquired or agreed to redeem, purchase or otherwise acquire any shares of
     Infocore's capital stock.

               3.12 Assets.  Infocore and its Subsidiaries have good and
                    ------                                              
     marketable title to all material assets owned by them constituting real
     property and good title to all material assets owned by them constituting
     personal property, including without limitation those assets reflected in
     the Infocore Financial Statements in the amounts and categories reflected
     therein, free and clear of all mortgages, liens, pledges, charges or
     encumbrances or other third party interests of any nature whatsoever,
     except (a) the lien of current taxes not yet due and payable, (b) assets
     disposed of by Infocore or any Subsidiary since December 31, 1996 solely in
     the ordinary course of business consistent with past practice, (c) such
     secured indebtedness, financing or capital lease obligations, or purchase
     money security interest as are disclosed in the Infocore Financial
     Statements covering the properties referred to therein, and (d) such other
     imperfections of title, easements, mortgages, liens, pledges, charges and
     encumbrances, if any, as do not materially detract from the value, or
     interfere with the present or proposed use, of the assets subject thereto.
     All tangible assets material to the operation of Infocore's business are in
     good working order and repair and comply in all material respects with
     applicable rules, regulations and standards regarding their intended use.
     Infocore's tangible assets meet, in all material respects, all current
     industry technical performance standards for assets of their particular
     design.  Infocore has an inventory of spare parts and other materials
     relating to its business of the type, nature and amount consistent with
     Infocore's past practices and good industry practices.

               3.13 Accounts Receivable.  The accounts receivable reflected on
                    -------------------                                       
     the Infocore Balance Sheet and arising thereafter to and including the
     Effective Date, arose, and will arise, from bona fide transactions in the
     ordinary course of business and are and will be fully collectible, subject
     to any reserve for doubtful accounts on the Infocore Balance Sheet.  The
     amount of accounts receivable reflected on the Infocore Balance Sheet is
     accurately reflected in the invoices and statements rendered by Infocore
     and its Subsidiaries.

               3.14 Contracts.
                    --------- 

                    (a) The Infocore Schedule sets forth each contract,
     agreement, note, debenture, bond, lease, mortgage, license, understanding,
     or arrangement to which Infocore or any Subsidiary is a party or may be
     bound, except for (i) those that may be terminated without liability or
     penalty on not more than thirty days notice, (ii) those under which the
     executory obligation requiring future performance of Infocore or any
     Subsidiary involves an individual amount of less than $1,000, or (iii)
     those under which the sole executory obligation of Infocore consists of
     outstanding equipment warranties (collectively the "Contracts").

<PAGE>
 
                    (b) All Contracts are in force in accordance with their
     terms. Neither Infocore nor any Subsidiary (nor any other party) has
     violated any material provision of, or committed or failed to perform any
     act which with notice, lapse of time or both would constitute a material
     default under the provisions of, any Contract. The Infocore Schedule
     identifies all Contracts which require the consent or approval of third
     parties to the execution and delivery of this Agreement or to the
     consummation and performance of the transactions contemplated hereby.

               3.15 Litigation.  No claim, action, suit, arbitration, or other
                    ----------                                                
     proceeding is pending, or known by Infocore to be threatened against
     Infocore or any Subsidiary or any of their properties before any court,
     governmental or regulatory official, body or authority, arbitrator or
     mediator.  To the knowledge of Infocore, no investigation is pending or
     threatened against Infocore or any Subsidiary or any of their properties
     before any court, governmental or regulatory official, body or authority,
     arbitrator or mediator.  There are no judgments, consent decrees,
     injunctions, or any other judicial or administrative mandates of any nature
     outstanding against Infocore or any Subsidiary.  There are no claims,
     actions, suits or other proceedings pending, or known by Infocore to be
     threatened, against any director or officer of Infocore.  To the knowledge
     of Infocore, no events have occurred which could reasonably be expected to
     form the basis for a claim or other proceedings against Infocore's
     directors or officers for breach of fiduciary duty.

               3.16 Insurance.  Each of Infocore and its Subsidiaries maintains
                    ---------                                                  
     insurance coverage on its structures, facilities, machinery, equipment and
     other assets and properties and with respect to its employees and
     operations which covers liabilities and risks customarily insured against
     by similar businesses on customary terms.  The Infocore Schedule contains a
     complete and accurate description of the insurance coverage applicable to
     Infocore and its Subsidiaries, including amounts and lines of coverage,
     terms, expiration date, premium and loss experience history by line of
     coverage.  All such policies are occurrence, rather than claims made
     policies.  There are no provisions in such policies for retroactive or
     retrospective premium adjustments.  The insurance binders and policies
     listed on the Infocore Schedule are valid and in full force and effect and
     will continue in full force and effect until the Effective Date.  Neither
     Infocore nor any Subsidiary has been refused any insurance by an insurance
     carrier to which it has applied for insurance during the past three years.
     Infocore and each Subsidiary has complied in all material respects with the
     provisions of such policies.

               3.17 Labor Matters.  Neither Infocore nor any Subsidiary is a
                    -------------                                           
     party to or bound by any collective bargaining agreements with respect to
     any employees of Infocore or any Subsidiary.  Since December 31, 1996,
     there has not been, nor to the knowledge of Infocore was there or is there
     threatened, any strike, slowdown, picketing or work stoppage by any union
     or other group of employees against Infocore or any Subsidiary or any of
     their premises, or any other labor trouble or other occurrence, event or
     condition of a similar character which may have an Infocore Material
     Adverse Effect.

               3.18 Employee Benefit Plans.
                    ---------------------- 

                    (a) With respect to each employee benefit plan (including,
     without limitation, any "employee benefit plan," as defined in Section 3(3)
     of ERISA) (all the foregoing being herein called "Benefit Plans"),
     maintained or contributed to by Infocore or any of its Subsidiaries,
     Infocore has made available to CEI a true and correct copy of (i) the most
     recent annual report (Form 5500) filed with the IRS, (ii) such Benefit
     Plan, (iii) each trust agreement and group annuity contract, if any,
     relating to such Benefit Plan and (iv) the most recent actuarial report or
     valuation relating to any Benefit Plan subject to Title IV of ERISA.

                    (b) With respect to the Benefit Plans, individually and in
     the aggregate, no event has occurred, and to the knowledge of Infocore,
     there exists no condition or set of circumstances in connection with which
     Infocore or any of its Subsidiaries is subject to any liability that could
     be reasonably expected to have an Infocore Material Adverse Effect, under
     ERISA, the Code or any other applicable law. All Benefit Plans conform to,
     and have been administered and operated in compliance, in all material
     respects, with the requirements of the applicable plan documents, ERISA,
     the Code and any other applicable law.

                    (c) With respect to the Benefit Plans, individually and in
     the aggregate, there are no material funded benefit obligations for which
     contributions have not been made or properly accrued and there are no
     material unfunded benefit obligations which have not been accounted for by
     reserves, or otherwise properly footnoted

                                      -8-

     in accordance with generally accepted accounting principles, on the
     consolidated financial statements of Infocore and its Subsidiaries.

                    (d) Each Benefit Plan that is intended to be qualified under
     Section 401(a) of the Code has received a favorable determination letter
     from the Internal Revenue Service.  No such Benefit Plan has been
     completely or partially terminated since December 31, 1992.

                    (e) No Benefit Plan, nor any fiduciary thereof, has engaged
     in a transaction which is reasonably likely to subject any Benefit Plan, or
     any fiduciary thereof, to any material taxes or penalties for a "prohibited
     transaction" (as defined in Section 406 of ERISA or Section 4975 of the
     Code) or any material penalty under Section 502 of ERISA.

               3.19 Franchises, Licenses, Permits, Etc.  Infocore and its
                    ----------------------------------                   
     Subsidiaries own or possess in the operation of their respective businesses
     all franchises, licenses, permits, consents, approvals, rights, waivers and
     other governmental authorizations ("Authorizations") which are material to
     the conduct of the business of Infocore and its Subsidiaries, taken as a
     whole.  Neither Infocore nor any Subsidiary is in material default, or has
     received any notice of any claim or material default, with respect to any
     such Authorization or any notice of any other material claim or proceeding
     or threatened proceeding relating to any such Authorization or claimed lack
     of any necessary material Authorization.  Neither the execution or delivery
     of this Agreement nor the consummation of the transactions contemplated
     hereby will require any notice or consent under or have any material
     adverse effect upon any such Authorization.

               3.20 Patents and Trademarks.  Except as set forth on the Infocore
                    ----------------------                                      
     Schedule, Infocore does not own, license or use in its business any
     material patents, trademarks, copyrights or other intellectual property
     assets.  Infocore and its Subsidiaries own (free and clear of all liens)
     all such patents, trademarks, tradenames, copyrights and applications with
     respect thereto and other intellectual property, have entered into a
     subsisting license agreement with respect thereto, or otherwise have
     adequate authority to use such intellectual property in the conduct of
     Infocore's business.  Neither Infocore nor any Subsidiary has received any
     notice or other information with respect to any alleged infringement or
     unlawful use of any such asset nor has Infocore or any Subsidiary granted
     or agreed to grant any license to use any such asset.

                    ---------------                                            
     Subsidiaries have conducted their business solely in the ordinary course
     consistent with past practice.  Without limitation of the foregoing, since

     part of the Registration Statement (the "Prospectus and Proxy Statement")
     to be filed with the SEC by CEI in connection with the issuance of CEI
     Common Stock pursuant to the Merger or any other documents to be filed with
     the SEC in connection with the transactions contemplated hereby will, at
     the respective times such documents are filed, and, in the case of the
     Registration Statement, when it becomes effective and at all times

     hereunder contains any untrue statement of material fact or omits to state
     a material fact necessary in order to make the statements contained therein
     or herein, in light of the circumstances in which they are made, not
     misleading.

               3.25 Tax Free Reorganization Matters.
                    ------------------------------- 

                    (a) To the best of the knowledge of the management of
     Infocore, there is no current plan or intention by the shareholders of
     Infocore to sell, exchange or otherwise dispose of a number of shares of
     CEI Common Stock received in the Merger that would reduce the former
     Infocore shareholders' ownership of CEI Common Stock to a number of shares
     having a value, as of the date of the Merger, of less than fifty percent
     (50%) of the value of all of the formerly outstanding capital stock of
     Infocore as of the same date. For purposes of this representation, shares
     of Infocore Common Stock exchanged for cash in lieu of fractional shares
     will be treated as outstanding Infocore stock on the date of the Merger.

                    (b) As a result of the Merger, Infocore will transfer and
     Sub will acquire at least ninety percent (90%) of the fair market value of
     the net assets and at least seventy percent (70%) of the fair market value
     of the gross assets held by Infocore immediately prior to the Merger. For
     purposes of this representation, the amount of Infocore assets used to pay
     Infocore reorganization expenses will be included as assets of Infocore
     held immediately prior to the Merger.

                    (c) The liabilities of Infocore assumed by Sub and the
     liabilities to which the transferred assets of Infocore are subject, if
     any, were incurred by Infocore in the ordinary course of its business.

                    (d) Infocore will pay its expenses, if any, incurred in
     connection with the Merger.

                    (e) Infocore is not under the jurisdiction of a court in a
     Title 11 or similar case within the meaning of Section 368(a)(3)(A) of the
     Code.

                    (f) Infocore is not an investment company as defined in
     Section 368(a)(2)(F)(iii) and (iv) of the Code.

               With respect to the Articles of Incorporation of CEI, the
     execution, delivery and performance by CEI of this Agreement and the
     transactions contemplated hereby will not (i) result in any violation,

     Subsidiaries at December 31, 1996 described above is referred to herein as
     the "CEI Balance Sheet".  Except as disclosed in the CEI SEC Documents, CEI
     is not a party to any material probable business combination for which
     financial statements are required to be disclosed pursuant to Section 3-05
     of Regulation S-X under the 1933 Act.

               4.8  Brokerage.  In connection with the transactions contemplated
                    ---------

               4.9  Reports.  CEI has previously furnished Infocore with true

     of the date of such document any untrue statement of a material fact or
     omitted to state a material fact required to be stated therein or necessary
     in order to make the statements therein, in light of the circumstances
     under which they were made, not misleading.  Each of such documents which
     is subject to the 1933 Act or the 1934 Act, or the regulations promulgated
     thereunder, complied in all material respects when filed in form with such
     Acts and the applicable regulations thereunder.  Each of the CEI SEC
     Documents was timely filed and all reports required to be filed by CEI with
     the SEC from the date of this Agreement through the Effective Date shall be
     timely filed.

               4.10 Information Supplied.  None of the information supplied or
                    --------------------

     incorporation by reference in the Registration Statement (including the
     Prospectus and Proxy Statement) to be filed with the SEC by CEI in
     connection with the issuance of CEI Common Stock pursuant to the Merger or
     any other documents to be filed with the SEC in connection with the
     transactions contemplated hereby will, at the respective times such
     documents are filed, and, in the case of the Registration Statement, when
     it becomes effective and at all times necessary to comply with the 1933
     Act, and, with respect to the Prospectus and Proxy Statement, when mailed
     and at all times through the Closing Date contain any untrue statement of
     material fact or omit to state any material fact necessary in order to make
     the statements therein, in light of the circumstances in which they are
     made, not

                                      -13-
<PAGE>
 
     misleading.  All documents filed by CEI and its Subsidiaries with the SEC
     and any other regulatory agency in connection with the Merger will comply
     in all material respects with the provisions of all applicable rules and
     regulations.

               4.11 Disclosure.  No representation or warranty hereunder or
                    ----------

     any written certificate, statement, or other document delivered by CEI
     hereunder contains any untrue statement of material fact or omits to state
     a material fact necessary in order to make the statements contained therein
     or herein, in light of the circumstances in which they are made, not

                    -----------                                          
     reacquire any of the shares of CEI Common Stock it will issue to the
     shareholders of Infocore pursuant to the Merger.  Following the Effective
     Date, Sub, CEI, and/or its affiliates will continue the historic business
     of Infocore and its Subsidiaries as presently conducted.  CEI presently
     controls Sub within the meaning of Section 368(c) of the Code, and
     following the Effective Date, Sub will not issue additional shares of its
     stock that would result in CEI losing control of Sub within the meaning of
     Section 368(c) of the Code.

               4.13 Absence of Adverse Changes.  Since December 31, 1996, there
                    --------------------------                                 
     has been no change in the business, assets, liabilities, financial
     condition, results of operations or prospects of CEI and its Subsidiaries,
     taken as a whole, which would constitute a CEI Material Adverse Effect.

principles on Infocore's most recent monthly financial statements); or (v)
Infocore enters into a preliminary or definitive agreement with a Third Party
relating to any of the transactions referred to in clauses (i) through (iv)

of any such inquiries or proposals. Any such notification shall include the
identity of the person making such proposal or request, the terms thereof, and
any other information with respect thereto as CEI may reasonably request.
Nothing contained in this Agreement shall be construed to prohibit Infocore from
(a) disclosing, under protection of an appropriate confidentiality agreement,
non-public information concerning Infocore to, and engaging in discussions and
negotiations concerning an Acquisition Transaction with, a person who has made a
bona fide offer to engage in an Acquisition Transaction for a consideration and
on terms which are more favorable to the Infocore shareholders than the terms of
the Merger, and who can reasonably be expected to consummate the Acquisition
Transaction on the terms that have been proposed, and which disclosure,
discussions and negotiations, in the judgment of Infocore, shall be required by
reason of the fiduciary obligations of the Board of Directors of Infocore and
(b) subject to Infocore's obligations under Section 8.5(a) hereof and only after
terminating this Agreement in accordance with Section 8.1(c)(iii) hereof,
accepting such offer for an Acquisition Transaction from such person which the

shareholders than the Merger contemplated hereby.

judgment) are, at the time this Agreement is submitted for approval to the

such person to deliver to CEI, on or prior to the Closing Date, a written
agreement, in the form attached hereto as Exhibit "A" acknowledging and agreeing
to abide by the limitations imposed by law in respect of the sale or other
disposition of CEI Common Stock received by such person pursuant to the Merger.

shareholders of such corporation, and the other parties hereto may rely on the
delivery of such a waiver as conclusive evidence of such judgment and the
validity of the waiver.

Conestoga Enterprises, Inc.

Attention:  Executive Vice President

Dear Sir:

   This letter is delivered to you in compliance with Section 5.10 of the
Agreement and Plan of Merger, dated March 14, 1997 (the "Agreement"), between
Infocore, Inc. ("Infocore"), Conestoga Enterprises, Inc. ("CEI") and CI Merger
Corporation ("Sub"), providing for the merger (the "Merger") of Infocore with
and into Sub.

   Pursuant to the Merger, the shares of outstanding Infocore common stock will
be converted into shares of CEI Common Stock, par value $5.00 per share ("CEI
Common Stock").

   The Merger is intended to qualify for federal income tax purposes as a
reorganization within the meaning of Section 368(a) of the Internal Revenue Code
of 1986, as amended (the "Code"). In this regard, as we understand is customary
in such merger transactions, you are seeking representations and covenants from
persons who are Infocore directors, Infocore executive officers or who hold five
percent (5%) or more of the outstanding Infocore common stock concerning their
intentions, as of the date hereof, to hold and not to dispose of CEI Common
Stock that they receive in the Merger ("Merger Stock").

   In addition, I understand that the resale by me of Merger Stock will be
subject to certain restrictions under the federal securities laws. In this
regard, as we understand is customary in such merger transactions, you are
seeking representations and covenants from persons who are Infocore directors,
Infocore executive officers or who hold five percent (5%) or more of the
outstanding Infocore common stock to the effect that any resale of such Merger
Stock will be performed in compliance with applicable federal securities laws.

Tax Matters

   The undersigned hereby represents to CEI that the undersigned has no plan or
intention to sell, exchange or otherwise dispose of any Merger Stock that is
received by the undersigned in the Merger. I understand that Saul, Ewing, 
<PAGE>
 
Remick & Saul will rely upon such representations and covenants in delivering
its tax opinions concerning the Merger.

Securities Law Matters
- ----------------------

   The undersigned hereby acknowledges, solely for the purpose of this
undertaking, that the undersigned may be deemed to be an "affiliate" of Infocore
as that term is used in paragraph (c) of Rule 145 under the Securities Act of
1933, as amended (the "Act").

   The undersigned represents and warrants to you that any shares of Merger
Stock which the undersigned shall receive in exchange for shares of common stock
of Infocore are not being acquired by the undersigned with a view to their
distribution except to the extent and in the manner provided for in paragraph
(d) of Rule 145 under the Act.

   The undersigned acknowledges that it has been advised by counsel for Infocore
of the provisions of the federal securities laws which relate to resales of
Merger Stock, to be received by the undersigned in connection with the Merger,
and the undersigned hereby undertakes to comply fully with such provisions.  The
undersigned also agrees that CEI may place the legend set forth below on the
certificate or certificates for any or all Merger Stock to be received by
<PAGE>
 
Conestoga Enterprises, Inc.

Page 2

the undersigned in connection with the Merger, may file stop-transfer
instructions with respect to such shares with the transfer agent for such shares
and may refuse to transfer such shares except upon delivery to CEI of an
opinion, in form and substance satisfactory to CEI, of counsel acceptable to CEI
to the effect that the proposed transfer of some or all of such shares does not
violate federal securities laws.

     Pursuant to the provisions of the preceding paragraph, the certificate or
certificates evidencing Merger Stock received by the undersigned may bear the
following legend:

        "The shares represented by this certificate have been issued or
   transferred to the registered owner hereof as of the result of a transaction
   to which Rule 145 under the Securities Act of 1933, as amended, applies.
   Such shares, therefore, are transferable only upon, and are otherwise subject
   to, certain conditions specified in a certain letter dated _________________,
   1997 from the registered owner hereof to Conestoga Enterprises, Inc. (a copy
   of which is on file with the Secretary of Conestoga Enterprises, Inc.), and
   no transfer of such shares shall be valid or effective until such conditions
   have been fulfilled."

   It is understood that CEI is required to file certain periodic reports under
the Securities Exchange Act of 1934, as amended, with the Securities and
Exchange Commission and that no sales of Merger Stock received by the
undersigned in the Merger may be made under Rule 145(d) unless CEI has informed
the undersigned that it has filed all such reports required to be filed during
the 12 months preceding a proposed sale. It is further understood that CEI will
promptly respond to requests by the undersigned as to the filing of such
reports.

                                                  Very truly yours,

                             EMPLOYMENT AGREEMENT
                             --------------------


          THIS AGREEMENT is made                         , 1997, by and between
                                 ------------------------
     CI MERGER CORPORATION (the "Company"), a Pennsylvania corporation, and
     HARRISON H. CLEMENT, JR. (the "Employee"), of
                                                   ----------------------------
                    , Pennsylvania.
     ---------------

                                  BACKGROUND


          Pursuant to an Agreement and Plan of Merger dated March 14, 1997, by
     and among Conestoga Enterprises, Inc. ("CEI"), Infocore, Inc. ("Infocore")
     and the Company, Infocore in the near future will be merged with and into
     the Company, which will be the surviving corporation. Pursuant to such plan
     of merger (the "Plan of Merger"), as of the Effective Date of the merger
     specified therein (the "Effective Date"), the corporate name of the Company
     will become "Infocore, Inc.". The Employee is currently President and Chief
     Executive Officer of Infocore and the parties have agreed that he shall be
     employed by the Company as of the Effective Date under the terms and
     provisions contained in this Agreement.


                                   AGREEMENT


          Therefore, each intending to be legally bound hereby, the parties
     agree as follows:

          1.   Employment and Employment Duties.  Under the terms and conditions
               --------------------------------                                 
     contained in this Agreement, the Company employs the Employee as President
     and Chief Executive Officer and the Employee accepts such employment. The
     Employee's employment duties shall be those specified for the President of
     the Company in the Company's by-laws and those additional duties,
     commensurate with such position, assigned by the Board of Directors of the
     Company (the "Board"). The Employee shall report directly to the Board. The
     Employee's employment shall be on a full-time basis and he shall not be
     engaged or employed in other business activities (whether for pecuniary
     advantage or not) during the term of this Agreement, except that he shall
     be permitted to serve on the boards of directors of business or charitable
     organizations, provided such service does not materially affect the
     performance
<PAGE>
 
     of his employment duties for the Company.  The Employee shall discharge his
     employment duties in a diligent and conscientious fashion.

          2.   Term.  The Employee's employment hereunder shall be for a period
               ----                                                            
     of two (2) years, commencing upon the Effective Date. Notwithstanding the
     foregoing: (i) the Company may terminate the Employee's employment at any
     time (A) upon fifteen (15) days prior written notice for any reason or for
     no reason, or (B) without prior notice for cause (as defined below); and
     (ii) the Employee may terminate the Employee's employment at any time
     without prior notice for any reason or for no reason. For purposes of this
     Agreement, the Employee's employment shall be deemed to have been
     terminated for cause in the event the Company terminates it as a result of:

               (a) the Employee's breach of his confidentiality obligations
     specified in Section 5;
               (b) the willful failure or refusal by the Employee to perform any
     of his material employment duties or his material obligations under this
     Agreement which shall not have ceased or been corrected within fifteen (15)
     days following a written warning from the Company; or
               (c) the commission of any act or the failure to act by the
     Employee which constitutes a crime or offense involving money or other
     property of any of the CEI Companies (as defined in Section 5) or which
     constitutes a felony in the jurisdiction involved.

          3.   Severance Compensation.
               ---------------------- 

               3.1  General Rule.  Unless the provisions of Section 3.2 apply,
                    ------------                                              
     in the event of the termination of the Employee's employment by the Company
     other than for cause prior to the expiration of the two (2) year term
     referred to in Section 2, the Company shall be obligated to pay to the
     Employee, within fifteen (15) days after the date of termination, an amount
     equal to the greater of: (i) fifty percent (50%) of the Employee's annual
     salary determined as of the date of termination of employment, or (ii) the
     aggregate salary otherwise payable to the Employee for the balance of the
     two (2) year term referred to in Section 2, determined as of the date of
     termination of employment.

               3.2  Change of Control.  If, during the term of this Agreement,
                    -----------------                                         
     the Employee's employment with the Company is terminated within ninety (90)
     days of the date of a change of control (as defined below), either
<PAGE>
 
     by the Employee or by the Company other than for cause, the Company shall
     pay to the Employee, within fifteen (15) days of the date of termination of
     employment, an amount equal to the greater of: (i) the amount payable to
     the Employee as determined by the application of the provisions of Section
     3.1, or (ii) one and one-half (1.5) times the Employee's annual salary,
     determined as of the date of termination of employment. The Company shall
     be obligated to make such payment in lieu of, and not in addition to, the
     Company's payment obligations under Section 3.1. For purposes of this
     Agreement, a change of control shall be deemed to have occurred in the
     event of: (i) the acquisition, directly or indirectly, by any person or
     entity, or persons or entities acting in concert, whether by purchase,
     merger, consolidation or otherwise, of voting power over that number of
     voting shares of the capital stock of either the Company or CEI which, when
     combined with the existing voting power of such persons or entities, would
     enable them to cast fifty percent (50%) or more of the votes which all
     shareholders of the Company or CEI, respectively, would be entitled to cast
     in the election of directors of either the Company or CEI, or (ii) the
     sale, lease, exchange or other transfer (in one transaction or a series of
     related transactions) of all, or substantially all, of the assets of the
     Company to a transferee other than CEI or a company or entity of which a
     controlling interest is owned by CEI.

               3.3  Termination for Cause.  In the event of the termination of
                    ---------------------                                     
     the Employee's employment at any time by the Company for cause, the Company
     shall have no obligation to pay the Employee any sums following the
     termination of his employment.

          4.   Compensation.  As compensation for the performance of his
               ------------                                             
     employment duties, during the term hereof the Company shall pay or provide
     to the Employee the following:

               (a) A salary in the annual amount of One Hundred Two Thousand
     Dollars ($102,000), payable in accordance with the Company's normal payroll
     practices in effect from time to time. The Employee's salary shall be
     reviewed by the Board at the same time and in the same manner as is
     customary for the employees of CEI and its subsidiaries and may be
     increased, in the sole discretion of the Board, based upon the Employee's
     satisfactory performance of his employment duties.

               (b) The provision of those fringe benefits which were provided to
     the Employee in his position as President and CEO of Infocore as of the
     Effective Date under plans or insurance policies maintained by the
<PAGE>
 
     Company from time to time, but in no event having benefits less than
     comparable to those of Infocore.  Such fringe benefits include four (4)
     weeks paid vacation, personal use of a Company automobile, medical health
     and disability insurance coverage, inclusion in the Company's 401(k) profit
     sharing plan and its officers' profit sharing plan, and reimbursement of
     business expenses under policies similar to those in effect with Infocore.

               (c) Maintenance of a life insurance policy insuring the
     Employee's life with a death benefit of Three Hundred Fifty Thousand
     Dollars ($350,000.00) payable to the beneficiary or beneficiaries
     designated by the Employee.

          5.   Confidentiality.  The Employee acknowledges that he has had, and
               ---------------                                                 
     in fulfilling his duties under this Agreement he will have, access to
     confidential information regarding the business and financial affairs of
     the Company, CEI, and/or the other subsidiaries of CEI (collectively, the
     "CEI Companies"). The Employee hereby agrees to hold all such information
     in the strictest confidence, to discuss such information only with
     authorized personnel of the CEI Companies, and, except as required by law
     or compelled by legal process, to refrain from disclosing such information
     to any other party, both during the term of this Agreement and after the
     termination hereof. The provisions of this Section 5 shall not apply to
     information which is or becomes generally available to or known by the
     public other than as a result of disclosure by the Employee.

          6.   Covenant Not to Compete.  The Employee agrees that, in order to
               -----------------------                                        
     protect the legitimate interests and property rights of the Employer, for a
     period of one (1) year after the termination of the Employee's employment
     with the Company (regardless of the reason for the termination), the
     Employee shall not:

               (a) Engage, directly or indirectly, either as owner, partner,
     agent, employee, consultant, member, or shareholder, or otherwise operate,
     control, join or participate in, lend money to, or be connected with any
     commercial enterprise or business which is engaged within the Territory (as
     defined below) in any facet of the wireless telecommunications business
     carried on by any of the CEI Companies as of the date of termination of the
     Employee's employment;

               (b) Approach, solicit, contact, or otherwise establish a business
     relationship with any customer of any of the CEI Companies or any
     prospective customer of any of the CEI Companies with whom any of such
     companies has had significant contact on or before the date of termination
     of the Employee's employment, for a
<PAGE>
 
     purpose related to the business carried on by any of the CEI Companies as
     of the date of termination of the Employee's employment;

               (c) Assist any other person, partnership, corporation, limited
     liability company, or other entity in the pursuit of the activities from
     which the Employee is prohibited in engaging under the provisions of
     Subsections (a) and (b) above; or

               (d) Induce by active solicitation any present or future employees
     or agents of the Company or the other CEI Companies to directly or
     indirectly engage in any competitive business or to terminate their
     employment with any of the CEI Companies.

     For purposes of this Agreement, the term "Territory" shall mean those
     geographical areas encompassed by the Reading, Pottsville, Sunbury, and
     Williamsport Basic Trading Areas, as defined by the Federal Communications
     Commission for the issuance of personal communication services licenses.
     Nothing contained in this Section 6 shall prohibit the Employee from:  (i)
     investing in and owning securities issued by any publicly-held company
     which are traded on any recognized securities exchange or in the over-the-
     counter market; or (ii) accepting employment, after termination of his
     employment with the Company, with a customer of the Company which is not a
     significant customer.

          7.   Equitable Relief.  The Employee recognizes and agrees that, in
               ----------------                                              
     the event of a breach or threatened breach of his covenants and obligations
     contained in Section 5 and/or Section 6 of this Agreement, the Company will
     suffer irreparable harm and damage, that such harm and damage may be
     extremely difficult or impossible to quantify, and that therefore the
     Company shall be entitled to injunctive relief. Nothing contained herein,
     however, shall be construed as precluding the Company from pursuing any
     other remedies available to it for such breach or threatened breach,
     including the recovery of damages at law.

          8.   Restrictions Excessive.  In the event the restrictions imposed by
               ----------------------                                           
     the covenant contained in Section 6 are deemed by any court having
     jurisdiction to be unreasonable or otherwise unenforceable by reason of
     their duration, territory or the scope of the activities prohibited, it is
     agreed by the parties that such court may construe and enforce this
     Agreement by reducing the time period, territory, or scope of activities to
     an extent which such court deems to be reasonable and enforceable.

          9.   Severability.  If any provision or provisions of this Agreement
               ------------                                                   
     shall be deemed to contravene or be invalid under the laws of any
     jurisdiction where this Agreement is in force, the parties agree that such
     contravention or invalidity shall not invalidate the entire Agreement, but
     it shall be construed as not containing the particular provision or
     provisions held to be invalid and the rights and obligations of the parties
     shall be construed and enforced accordingly.

          10.  Miscellaneous.
               ------------- 
               (a) This Agreement shall be construed, interpreted and enforced
     in accordance with the laws (but not the law of conflict of laws) of the
     Commonwealth of Pennsylvania.

               (b) This Agreement and its provisions shall be binding upon and
     inure to the benefit of the respective legal representatives, successors,

     any of his rights nor delegate any of his duties under this Agreement
     without the prior written consent of the Company.

               (c) This Agreement constitutes the entire Agreement between the
     parties and supersedes all prior negotiations, understandings and
     agreements of any nature whatsoever, whether oral or written, with respect
     to the subject matter hereof. No amendment, waiver or discharge of any
     provision of this Agreement shall be effective against any party, unless
     that party shall have consented thereto in writing.

                             --------------------


          THIS AGREEMENT is made                         , 1997, by and between
                                 ------------------------
     CI MERGER CORPORATION (the "Company"), a Pennsylvania corporation, and
     HENRY M. STRINGER (the "Employee"), of
                                            ------------------------------------
                     , Pennsylvania.
     ----------------

                                  BACKGROUND


          Pursuant to an Agreement and Plan of Merger dated March 14, 1997, by
     and among Conestoga Enterprises, Inc. ("CEI"), Infocore, Inc. ("Infocore")
     and the Company, Infocore in the near future will be merged with and into

     plan of merger (the "Plan of Merger"), as of the Effective Date of the
     merger specified therein (the "Effective Date"), the corporate name of the
     Company will become "Infocore, Inc.". The Employee is currently Senior Vice
     President of Infocore and the parties have agreed that he shall be employed
     by the Company as of the Effective Date under the terms and provisions
     contained in this Agreement.


                                   AGREEMENT


          Therefore, each intending to be legally bound hereby, the parties
     agree as follows:

          1.   Employment and Employment Duties.  Under the terms and conditions
               --------------------------------                                 
     contained in this Agreement, the Company employs the Employee as Senior
     Vice President and the Employee accepts such employment. The Employee's
     employment duties shall include primary management of the Company's sales
     and marketing functions and those additional duties, commensurate with his
     position, assigned by the President and/or the Board of Directors of the
     Company (the "Board"). The Employee shall report directly to the President.
     The Employee's employment shall be on a full-time basis and he shall not be
     engaged or employed in other business activities (whether for pecuniary
     advantage or not) during the term of this Agreement. The Employee shall
     discharge his employment duties in a diligent and conscientious fashion.
<PAGE>
 
          2.   Term.  The Employee's employment hereunder shall be for a period
               ----                                                            
     of two (2) years, commencing upon the Effective Date.  Notwithstanding the
     foregoing:  (i) the Company may terminate the Employee's employment at any
     time (A) upon fifteen (15) days prior written notice for any reason or for
     no reason, or (B) without prior notice for cause (as defined below); and
     (ii) the Employee may terminate the Employee's employment at any time
     without prior notice for any reason or for no reason. For purposes of this
     Agreement, the Employee's employment shall be deemed to have been
     terminated for cause in the event the Company terminates it as a result of:

               (a) the Employee's breach of his confidentiality obligations
     specified in Section 5;

               (b) the willful failure or refusal by the Employee to perform any
     of his material employment duties or his material obligations under this
     Agreement which shall not have ceased or been corrected within fifteen (15)
     days following a written warning from the Company; or

               (c) the commission of any act or the failure to act by the
     Employee which constitutes a crime or offense involving money or other
     property of any of the CEI Companies (as defined in Section 5) or which
     constitutes a felony in the jurisdiction involved.

          3.   Severance Compensation.
               ---------------------- 

               3.1  General Rule.  Unless the provisions of Section 3.2 apply,
                    ------------                                              
     in the event of the termination of the Employee's employment by the Company
     other than for cause prior to the expiration of the two (2) year term
     referred to in Section 2, the Company shall be obligated to pay to the
     Employee, within fifteen (15) days after the date of termination, an amount
     equal to the greater of: (i) fifty percent (50%) of the Employee's annual
     salary determined as of the date of termination of employment, or (ii) the
     aggregate salary otherwise payable to the Employee for the balance of the
     two (2) year term referred to in Section 2, determined as of the date of
     termination of employment.

               3.2  Change of Control.  If, during the term of this Agreement,
                    -----------------                                         
     the Employee's employment with the Company is terminated within ninety (90)
     days of the date of a change of control (as defined below), either by the
     Employee or by the Company other than for cause, the Company shall pay to
     the Employee, within fifteen (15) days of the date of termination of
     employment, an amount equal to the greater of:  (i) the amount payable to
<PAGE>
 
     the Employee as determined by the application of the provisions of Section
     3.1, or (ii) the amount of the Employee's annual salary, determined as of
     the date of termination of employment. The Company shall be obligated to
     make such payment in lieu of, and not in addition to, the Company's payment
     obligations under Section 3.1. For purposes of this Agreement, a change of
     control shall be deemed to have occurred in the event of: (i) the
     acquisition, directly or indirectly, by any person or entity, or persons or
     entities acting in concert, whether by purchase, merger, consolidation or
     otherwise, of voting power over that number of voting shares of the capital
     stock of either the Company or CEI which, when combined with the existing
     voting power of such persons or entities, would enable them to cast fifty
     percent (50%) or more of the votes which all shareholders of the Company or
     CEI, respectively, would be entitled to cast in the election of directors
     of either the Company or CEI, or (ii) the sale, lease, exchange or other
     transfer (in one transaction or a series of related transactions) of all,
     or substantially all, of the assets of the Company to a transferee other
     than CEI or a company or entity of which a controlling interest is owned by
     CEI.

               3.3  Termination for Cause.  In the event of the termination of
                    ---------------------                                     
     the Employee's employment at any time by the Company for cause, the Company
     shall have no obligation to pay the Employee any sums following the
     termination of his employment.

          4.   Compensation.  As compensation for the performance of his
               ------------                                             
     employment duties, during the term hereof the Company shall pay or provide
     to the Employee the following:

               (a) A salary in the annual amount of Ninety Thousand Dollars
     ($90,000), payable in accordance with the Company's normal payroll
     practices in effect from time to time. The Employee's salary shall be
     reviewed by the Board at the same time and in the same manner as is
     customary for the employees of CEI and its subsidiaries and may be
     increased, in the sole discretion of the Board, based upon the Employee's
     satisfactory performance of his employment duties.

               (b) The provision of those fringe benefits which were provided to
     the Employee in his position as Senior Vice President of Infocore as of the
     Effective Date under plans or insurance policies maintained by the Company
     from time to time, but in no event having benefits less than comparable to
     those of Infocore. Such fringe benefits include four (4) weeks paid
     vacation, personal use of a Company automobile, medical health and
     disability
<PAGE>
 
     insurance coverage, inclusion in the Company's 401(k) profit sharing plan
     and its officers' profit sharing plan, and reimbursement of business
     expenses under policies similar to those in effect with Infocore.

               (c) Maintenance of a life insurance policy insuring the
     Employee's life with a death benefit of Three Hundred Fifty Thousand
     Dollars ($350,000.00) payable to the beneficiary or beneficiaries
     designated by the Employee.

          5.   Confidentiality.  The Employee acknowledges that he has had, and
               ---------------                                                 
     in fulfilling his duties under this Agreement he will have, access to
     confidential information regarding the business and financial affairs of
     the Company, CEI, and/or the other subsidiaries of CEI (collectively, the
     "CEI Companies"). The Employee hereby agrees to hold all such information
     in the strictest confidence, to discuss such information only with
     authorized personnel of the CEI Companies, and, except as required by law
     or compelled by legal process, to refrain from disclosing such information
     to any other party, both during the term of this Agreement and after the
     termination hereof. The provisions of this Section 5 shall not apply to
     information which is or becomes generally available to or known by the
     public other than as a result of disclosure by the Employee.

          6.   Covenant Not to Compete.  The Employee agrees that, in order to
               -----------------------                                        
     protect the legitimate interests and property rights of the Employer, for a
     period of one (1) year after the termination of the Employee's employment
     with the Company (regardless of the reason for the termination), the
     Employee shall not:

               (a) Engage, directly or indirectly, either as owner, partner,
     agent, employee, consultant, member, or shareholder, or otherwise operate,
     control, join or participate in, lend money to, or be connected with any
     commercial enterprise or business which is engaged within the Territory (as
     defined below) in any facet of the wireless telecommunications business
     carried on by any of the CEI Companies as of the date of termination of the
     Employee's employment;

               (b) Approach, solicit, contact, or otherwise establish a business
     relationship with any customer of any of the CEI Companies or any
     prospective customer of any of the CEI Companies with whom any of such
     companies has had significant contact on or before the date of termination
     of the Employee's employment, for a purpose related to the business carried
     on by any of the CEI Companies as of the date of termination of the
     Employee's employment;
<PAGE>
 
               (c) Assist any other person, partnership, corporation, limited
     liability company, or other entity in the pursuit of the activities from

               (d) Induce by active solicitation any present or future employees
     or agents of the Company or the other CEI Companies to directly or
     indirectly engage in any competitive business or to terminate their
     employment with any of the CEI Companies.

     For purposes of this Agreement, the term "Territory" shall mean those
     geographical areas encompassed by the Reading, Pottsville, Sunbury, and
     Williamsport Basic Trading Areas, as defined by the Federal Communications
     Commission for the issuance of personal communication services licenses.
     Nothing contained in this Section 6 shall prohibit the Employee from:  (i)
     investing in and owning securities issued by any publicly-held company
     which are traded on any recognized securities exchange or in the over-the-
     counter market; or (ii) accepting employment, after termination of his
     employment with the Company, with a customer of the Company which is not a
     significant customer.

          7.   Equitable Relief.  The Employee recognizes and agrees that, in
               ----------------                                              
     the event of a breach or threatened breach of his covenants and obligations
     contained in Section 5 and/or Section 6 of this Agreement, the Company will
     suffer irreparable harm and damage, that such harm and damage may be
     extremely difficult or impossible to quantify, and that therefore the
     Company shall be entitled to injunctive relief. Nothing contained herein,
     however, shall be construed as precluding the Company from pursuing any
     other remedies available to it for such breach or threatened breach,
     including the recovery of damages at law.

          8.   Restrictions Excessive.  In the event the restrictions imposed by
               ----------------------                                           
     the covenant contained in Section 6 are deemed by any court having
     jurisdiction to be unreasonable or otherwise unenforceable by reason of
     their duration, territory or the scope of the activities prohibited, it is
     agreed by the parties that such court may construe and enforce this
     Agreement by reducing the time period, territory, or scope of activities to
     an extent which such court deems to be reasonable and enforceable.

          9.   Severability.  If any provision or provisions of this Agreement
               ------------                                                   
     shall be deemed to contravene or be invalid under the laws of any
     jurisdiction where this Agreement is in force, the parties agree that such
<PAGE>
 
     contravention or invalidity shall not invalidate the entire Agreement, but
     it shall be construed as not containing the particular provision or
     provisions held to be invalid and the rights and obligations of the parties
     shall be construed and enforced accordingly.

          10.  Miscellaneous.
               ------------- 
               (a) This Agreement shall be construed, interpreted and enforced
     in accordance with the laws (but not the law of conflict of laws) of the
     Commonwealth of Pennsylvania.

               (b) This Agreement and its provisions shall be binding upon and
     inure to the benefit of the respective legal representatives, successors,
     heirs, and permitted assigns of the parties.  The Employee shall not assign
     any of his rights nor delegate any of his duties under this Agreement
     without the prior written consent of the Company.

telecommunications, broadcasting and cable industries. JSI has performed
valuations of telecommunications concerns for a variety of purposes including
mergers and acquisitions, divestitures, gift and estate taxes, employee stock
ownership plans, financial restructurings, and other objectives.

In arriving at our opinion, we have, among other things, (i) considered the
nature and economic outlook of the telecommunications industry, (ii) the
financial and operating history of Conestoga and Infocore, (iii) Conestoga's and
Infocore's earnings and cash flow for the last three years and management's
assessment for future earnings and cash flow, (iv) price and trading ranges for
Conestoga's Common Stock over the prior 33 months, and (v) the value of revenue
streams and other identifiable assets or benefits associated with the Infocore
acquisition.

Specific documents and information relied upon and procedures performed in
arriving at our opinion included reviewing Conestoga's and Infocore's audited
financial statements for the periods December 31, 1994 through December 31,
1996; reviewing Securities and Exchange Commission Forms 10-K filed by
Conestoga for the fiscal years ending December 31, 1991 through December 31,
1995; reviewing the history of Conestoga's stock transfer prices for the period
June 1, 1994 through March 14, 1997; reviewing the Merger Agreement; having
discussions with Conestoga management about the Merger and current and future
business prospects for both Conestoga and Infocore; and performing such
<PAGE>
 
other analysis and considering such other factors as we deemed appropriate.

In rendering this opinion, we have relied, without independent verification, on
the accuracy, completeness, and fairness of all financial and other information
that was publicly available or furnished to us by Conestoga, Infocore and/or
their advisors.

Based upon our analysis of the factors deemed relevant, it is our opinion that,
as of the date of this letter, the Consideration to be paid pursuant to the
Merger is fair, from a financial point of view, to the shareholders of
Conestoga.

Very truly yours,

JSI Financial Services

               (1) Except as otherwise provided in paragraph (2), the holders of
          the shares of any class or series of shares that, at the record date
          fixed to determine the shareholders entitled to notice of and to vote
          at the meeting at which a plan specified in any of section 1930,
          1931(d), 1932(c) or 1952(d) is to be voted on, are either:

               fractional shares.

                                      C-1
<PAGE>
 
                    (ii) Shares of any preferred or special class unless the
               articles, the plan or the terms of the transaction entitle all
               shareholders of the class to vote thereon and require for the
               adoption of the plan or the effectuation of the transaction the
               affirmative vote of a majority of the votes cast by all
               shareholders of the class.

                    (iii) Shares entitled to dissenters rights under section
               1906(c) (relating to dissenters rights upon special treatment).

               (3) The shareholders of a corporation that acquires by purchase,
          lease, exchange or other disposition all or substantially all of the
          shares, property or assets of another corporation by the issuance of
          shares, obligations or otherwise, with or without assuming the
          liabilities of the other corporation and with or without the
          intervention of another corporation or other person, shall not be
          entitled to the rights and remedies of dissenting shareholders
          provided in this subchapter regardless of the fact, if it be the case,
          that the acquisition was accomplished by the issuance of voting shares
          of the corporation to be outstanding immediately after the acquisition
          sufficient to elect a majority or more of the directors of the
          corporation.

          (c) Grant of optional dissenters rights.--The bylaws or a resolution
of the board of directors may direct that all or a part of the shareholders
shall have dissenters rights in connection with any corporate action or other
transaction that would otherwise not entitle such shareholders to dissenters
rights.

          (d) Notice of dissenters rights.--Unless otherwise provided by
statute, if a proposed corporate action that would give rise to dissenters
rights under this subpart is submitted to a vote at a meeting of shareholders,
there shall be included in or enclosed with the notice of meeting:

               (1) a statement of the proposed action and a statement that the
          shareholders have a right to dissent and obtain payment of the fair
          value of their shares by complying with the terms of this subchapter;
          and

               (2) a copy of this subchapter.

          (e) Other statutes.--The procedures of this subchapter shall also be
applicable to any transaction described in any statute other than this part that
makes reference to this subchapter for the purpose of granting dissenters
rights.

          (f) Certain provisions of articles ineffective.--This subchapter may
not be relaxed by any provision of the articles.

          (g) Cross references.--See sections 1105 (relating to restriction on
equitable relief), 1904 (relating to de facto transaction doctrine abolished)
and 2512 (relating to dissenters rights procedure).


(S) 1572.  Definitions

          The following words and phrases when used in this subchapter shall
have the meanings given to them in this section unless the context clearly
indicates otherwise:

          "Corporation."  The issuer of the shares held or owned by the
dissenter before the corporate action or the successor by merger, consolidation,
division, conversion or otherwise of that issuer. A plan of division may
designate which of the resulting corporations is the successor corporation for
the purposes of this subchapter. The successor corporation in a division shall
have sole responsibility for payments to dissenters and other liabilities under
this subchapter except as otherwise provided in the plan of division.

                                      C-2
<PAGE>
 
          "Dissenter."  A shareholder or beneficial owner who is entitled to and
does assert dissenters rights under this subchapter and who has performed every
act required up to the time involved for the assertion of those rights.

          "Fair value."  The fair value of shares immediately before the
effectuation of the corporate action to which the dissenter objects, taking into
account all relevant factors, but excluding any appreciation or depreciation in
anticipation of the corporate action.

          "Interest."  Interest from the effective date of the corporate action
until the date of payment at such rate as is fair and equitable under all the
circumstances, taking into account all relevant factors, including the average
rate currently paid by the corporation on its principal bank loans.


(S) 1573.  Record and beneficial holders and owners

          (a) Record holders of shares.--A record holder of shares of a business
corporation may assert dissenters rights as to fewer than all of the shares
registered in his name only if he dissents with respect to all the shares of the
same class or series beneficially owned by any one person and discloses the name
and address of the person or persons on whose behalf he dissents. In that event,
his rights shall be determined as if the shares as to which he has dissented and
his other shares were registered in the names of different shareholders.

          (b) Beneficial owners of shares.--A beneficial owner of shares of a
business corporation who is not the record holder may assert dissenters rights
with respect to shares held on his behalf and shall be treated as a dissenting
shareholder under the terms of this subchapter if he submits to the corporation
not later than the time of the assertion of dissenters rights a written consent
of the record holder. A beneficial owner may not dissent with respect to some
but less than all shares of the same class or series owned by the owner, whether
or not the shares so owned by him are registered in his name.


(S) 1574.  Notice of intention to dissent

          If the proposed corporate action is submitted to a vote at a meeting
of shareholders of a business corporation, any person who wishes to dissent and
obtain payment of the fair value of his shares must file with the corporation,
prior to the vote, a written notice of intention to demand that he be paid the
fair value for his shares if the proposed action is effectuated, must effect no
change in the beneficial ownership of his shares from the date of such filing
continuously through the effective date of the proposed action and must refrain
from voting his shares in approval of such action. A dissenter who fails in any
respect shall not acquire any right to payment of the fair value of his shares
under this subchapter. Neither a proxy nor a vote against the proposed corporate
action shall constitute the written notice required by this section.


(S) 1575.  Notice to demand payment

          (a) General rule.--If the proposed corporate action is approved by the
required vote at a meeting of shareholders of a business corporation, the
corporation shall mail a further notice to all dissenters who gave due notice of
intention to demand payment of the fair value of their shares and who refrained
from voting in favor of the proposed action. If the proposed corporate action is
to be taken without a vote of shareholders, the corporation shall send to all
shareholders who are entitled to dissent and demand payment of the fair value of
their shares a notice of the adoption of the plan or other corporate action. In
either case, the notice shall:

              (1) State where and when a demand for payment must be sent and
          certificates for certificated shares must be deposited in order to
          obtain payment.

                                      C-3
<PAGE>
 
               (2) Inform holders of uncertificated shares to what extent
          transfer of shares will be restricted from the time that demand for
          payment is received.

               (3) Supply a form for demanding payment that includes a request
          for certification of the date on which the shareholder, or the person
          on whose behalf the shareholder dissents, acquired beneficial
          ownership of the shares.

               (4) Be accompanied by a copy of this subchapter.

          (b) Time for receipt of demand for payment.--The time set for receipt
of the demand and deposit of certificated shares shall be not less than 30 days
from the mailing of the notice.


(S) 1576.  Failure to comply with notice to demand payment, etc.

          (a) Effect of failure of shareholder to act.--A shareholder who fails
to timely demand payment, or fails (in the case of certificated shares) to
timely deposit certificates, as required by a notice pursuant to section 1575
(relating to notice to demand payment) shall not have any right under this
subchapter to receive payment of the fair value of his shares.

          (b) Restriction on uncertificated shares.--If the shares are not
represented by certificates, the business corporation may restrict their
transfer from the time of receipt of demand for payment until effectuation of
the proposed corporate action or the release of restrictions under the terms of
section 1577(a) (relating to failure to effectuate corporate action).

          (c) Rights retained by shareholder.--The dissenter shall retain all
other rights of a shareholder until those rights are modified by effectuation of
the proposed corporate action.


(S) 1577.  Release of restrictions or payment for shares

          (a) Failure to effectuate corporate action.--Within 60 days after the
date set for demanding payment and depositing certificates, if the business
corporation has not effectuated the proposed corporate action, it shall return
any certificates that have been deposited and release uncertificated shares from
any transfer restrictions imposed by reason of the demand for payment.

          (b) Renewal of notice of demand payment.--When uncertificated shares
have been released from transfer restrictions and deposited certificates have
been returned, the corporation may at any later time send a new notice
conforming to the requirements of section 1575 (relating to notice to demand
payment), with like effect.

          (c) Payment of fair value of shares.--Promptly after effectuation of
the proposed corporate action, or upon timely receipt of demand for payment if
the corporate action has already been effectuated, the corporation shall either
remit to dissenters who have made demand and (if their shares are certificated)
have deposited their certificates the amount that the corporation estimates to
be the fair value of the shares, or give written notice that no remittance under
this section will be made. The remittance or notice shall be accompanied by:

               (1) The closing balance sheet and statement of income of the
          issuer of the shares held or owned by the dissenter for a fiscal year
          ending not more than 16 months before the  date of remittance or
          notice together with the latest available interim financial
          statements.

               (2) A statement of the corporation's estimate of the fair value
          of the shares.

                                      C-4
<PAGE>
 
               (3) A notice of the right of the dissenter to demand payment or
          supplemental payment, as the case may be, accompanied by a copy of
          this subchapter.

          (d) Failure to make payment.--If the corporation does not remit the
amount of its estimate of the fair value of the shares as provided by subsection
(c), it shall return any certificates that have been deposited and release
uncertificated shares from any transfer restrictions imposed by reason of the
demand for payment. The corporation may make a notation on any such certificate
or on the records of the corporation relating to any such uncertificated shares
that such demand has been made. If shares with respect to which notation has
been made shall be transferred, each new certificate issued therefor or the
records relating to any transferred uncertificated shares shall bear a similar
notation, together with the name of the original dissenting holder or owner of
such shares. A transferee of such shares shall not acquire by such transfer any
rights in the corporation other than those that the original dissenter had after
making demand for payment of their fair value.


(S) 1578.  Estimate by dissenter of fair value of shares

          (a) General rule.--If the business corporation gives notice of its
estimate of the fair value of the shares, without remitting such amount, or
remits payment of its estimate of the fair value of a dissenter's shares as
permitted by section 1577(c) (relating to payment of fair value of shares) and
the dissenter believes that the amount stated or remitted is less than the fair
value of his shares, he may send to the corporation his own estimate of the fair
value of the shares, which shall be deemed a demand for payment of the amount or
the deficiency.

          (b) Effect or failure to file estimate.--Where the dissenter does not
file his own estimate under subsection (a) within 30 days after the mailing by
the corporation of its remittance or notice, the dissenter shall be entitled to
no more than the amount stated in the notice or remitted to him by the
corporation.


(S) 1579.  Valuation proceedings generally

          (a) General rule.--Within 60 days after the latest of:

               (1) effectuation of the proposed corporate action;

               (2) timely receipt of any demands for payment under section 1575
          (relating to notice to demand payment); or

               (3) timely receipt of any estimates pursuant to section 1578
          (relating to estimate by dissenter of fair value of shares);

if any demands for payment remain unsettled, the business corporation may
file in court an application for relief requesting that the fair value of
the shares be determined by the court.

          (b) Mandatory joinder of dissenters.--All dissenters, wherever
residing, whose demands have not been settled shall be made parties to the
proceeding as in an action against their shares. A copy of the application shall
be served on each such dissenter. If a dissenter is a nonresident, the copy may
be served on him in the manner provided or prescribed by or pursuant to 42
Pa.C.S. Ch. 53 (relating to bases of jurisdiction and interstate and
international procedure)./1/

<PAGE>
 
          (c) Jurisdiction of the court.--The jurisdiction of the court shall be
plenary and exclusive. The court may appoint an appraiser to receive evidence
and recommend a decision on the issue of fair value. The appraiser shall have
such power and authority as may be specified in the order of appointment or in
any amendment thereof.

          (d) Measure of recovery.--Each dissenter who is made a party shall be
entitled to recover the amount by which the fair value of his shares is found to
exceed the amount, if any, previously remitted, plus interest.

          (e) Effect of corporation's failure to file application.--If the
corporation fails to file an application as provided in subsection (a), any
dissenter who made a demand and who has not already settled his claim against
the corporation may do so in the name of the corporation at any time within 30
days after the expiration of the 60-day period. If a dissenter does not file an
application within the 30-day period, each dissenter entitled to file an
application shall be paid the corporation's estimate of the fair value of the
shares and no more, and may bring an action to recover any amount not previously
remitted.


(S) 1580.  Costs and expenses of valuation proceedings

          (a) General rule.--The costs and expenses of any proceeding under
section 1579 (relating to valuation proceedings generally), including the
reasonable compensation and expenses of the appraiser appointed by the court,
shall be determined by the court and assessed against the business corporation
except that any part of the costs and expenses may be apportioned and assessed
as the court deems appropriate against all or some of the dissenters who are
parties and whose action in demanding supplemental payment under section 1578
(relating to estimate by dissenter of fair value of shares) the court finds to
be dilatory, obdurate, arbitrary, vexatious or in bad faith.

          (b) Assessment of counsel fees and expert fees where lack of good
faith appears.--Fees and expenses of counsel and of experts for the respective
parties may be assessed as the court deems appropriate against the corporation
and in favor of any or all dissenters if the corporation failed to comply
substantially with the requirements of this subchapter and may be assessed
against either the corporation or a dissenter, in favor of any other party, if
the court finds that the party against whom the fees and expenses are assessed
acted in bad faith or in a dilatory, obdurate, arbitrary or vexatious manner in
respect to the rights provided in this subchapter.

          (c) Award of fees for benefits to other dissenters.--If the court
finds that the services of counsel for any dissenter were of substantial benefit
to other dissenters similarly situated and should not be assessed against the
corporation, it may award to those counsel reasonable fees to be paid out of the
amounts awarded to the dissenters who were benefited.

                                    PART II

                     INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20.  Indemnification of Directors and Officers


       Sections 1741 and 1742 of the Pennsylvania Business Corporation Law of
1988, as amended (the "PBCL"), provide that a business corporation may indemnify
directors and officers against liabilities that they may incur as such provided
that the particular person acted in good faith and in a manner he or she
reasonably believed to be in, or not opposed to, the best interests of the
corporation, and, with respect to any criminal proceeding, had no reasonable
cause to believe his or her conduct was unlawful. In the case of actions against
a director or officer by or in the right of the corporation, the power to
indemnify extends only to expenses (not judgments and amounts paid in
settlement) and such power generally does not exist if the person otherwise
entitled to indemnification shall have been adjudged to be liable to the
corporation unless it is judicially determined that, despite the adjudication of
liability but in view of all the circumstances of the case, the person is fairly
and reasonably entitled to indemnification for specified expenses. Under Section
1743 of the PBCL, the corporation is required to indemnify directors and
officers against expenses they may incur in defending actions against them in
such capacities if they are successful on the merits or otherwise in the defense
of such actions. Under Section 1745 of the PBCL, a corporation may pay the
expenses of a director or officer incurred in defending an action or proceeding
in advance of the final disposition thereof upon receipt of an undertaking from
such person to repay the amounts advanced unless it is ultimately determined
that such person is entitled to indemnification from the corporation.

       Section 1746 of the PBCL grants a corporation broad authority to
indemnify its directors, officers and other agents for liabilities and expenses
incurred in such capacity, except in circumstances where the act or failure to
act giving rise to the claim for indemnification is determined by a court to
have constituted willful misconduct or recklessness. Pursuant to the authority
of Section 1746 of the PBCL, the CEI Bylaws provide that in connection with any
action, suit or proceeding in which a person may be involved by reason of being
or having been a director, officer, employee or agent of CEI, the directors and
officers of CEI shall be indemnified to the fullest extent permitted by law,
except for liabilities arising under the Securities Act of 1933, as amended.

       As authorized by Section 1747 of the PBCL, CEI maintains, on behalf of
its directors and officers, insurance protection against certain liabilities
arising out of the discharge of their duties, as well as insurance covering CEI
for indemnification payments made to its directors and officers for certain
liabilities. The premiums for such insurance are paid by CEI.

Item 22.  Undertakings

(1)    The undersigned registrant hereby undertakes:

(a)    To file, during any period in which offers or sales are being made, a
       post-effective amendment to this registration statement:

(i)    To include any prospectus required by section 10(a)(3) of the
       Securities Act of 1933;

(ii)   To reflect in the prospectus any facts or events arising after the
       effective date of the registration statement (or the most recent post-
       effective amendment thereof) which, individually or in the aggregate,
       represent a fundamental change in the information set forth in the
       registration statement;

(iii)  To include any material information with respect to the plan of
       distribution not previously disclosed in the registration statement or
       any material change to such information in the registration statement.

(b)    That, for the purpose of determining any liability under the
       Securities Act of 1933, each such post-effective amendment shall be
       deemed to be a new registration statement relating to the securities
       offered therein, and the offering of such securities at that time
       shall be deemed to be the initial bona fide offering thereof.

(c)    To remove from registration by means of a post-effective amendment any
       of the securities being registered which remain unsold at the
       termination of the offering.

(2)    The undersigned registrant hereby undertakes to respond to requests for
       information that is incorporated by reference into the prospectus
       pursuant to Items 4, 10(b), 11, or 13 of this Form, within one business
       day of receipt of such request, and to send the incorporated documents by
       first class mail or other equally prompt means. This includes information
       contained in documents filed subsequent to the effective date of the
       registration statement through the date of responding to the request.

(3)    The undersigned registrant hereby undertakes to supply by means of a 
       post-effective amendment all information concerning a transaction, and
       the company being acquired involved therein, that was not the subject of
       and included in the registration statement when it became effective.

(4)    The undersigned registrant hereby undertakes that, for purposes of
       determining any liability under the Securities Act of 1933, each filing
       of the registrant's annual report pursuant to section 13(a) or section
       15(d) of the Securities Exchange Act of 1934 (and, where applicable, each
       filing of an employee benefit plan's annual report pursuant to section
       15(d) of the Securities Exchange Act of 1934) that is incorporated by
       reference in the registration statement shall be deemed to be a new
       registration statement relating to the securities offered therein, and
       the offering of such securities at that time shall be deemed to be the
       initial bona fide offering thereof.

(5)    Insofar as indemnification for liabilities arising under the Securities
       Act of 1933 may be permitted to directors, officers and controlling
       persons of the registrant pursuant to the foregoing provisions, or
       otherwise, the registrant has been advised that in the opinion of the
       Securities and Exchange Commission such indemnification is against public
       policy as expressed in the Act and is, therefore, unenforceable. In the
       event that a claim for indemnification against such liabilities (other
       than the payment by the registrant of expenses incurred or paid by a
       director, officer or controlling person of the registrant in the
       successful defense of any action, suit or proceeding) is asserted by such
       director, officer or controlling person in connection with the securities
       being registered, the registrant will, unless in the opinion of its
       counsel the matter has been settled by controlling precedent, submit to a
       court of appropriate jurisdiction the question whether such
       indemnification by it is against public policy as expressed in the Act
       and will be governed by the final adjudication of such issue.

                                      C-3
<PAGE>
 
(6)    The undersigned registrant hereby undertakes that:

(a)    For purposes of determining any liability under the Securities Act of
       1933, the information omitted from the prospectus filed as part of this
       registration statement in reliance upon Rule 430A and contained in a form
       of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4)
       or 497(h) under the Securities Act shall be deemed to be part of this
       registration statement as of the time it was declared effective.

(b)    For the purpose of determining any liability under the Securities Act of
       1933, each post-effective amendment that contains a form of prospectus
       shall be deemed to be a new registration statement relating to the
       securities offered therein, and the offering of such securities at that
       time shall be deemed to be the initial bona fide offering thereof.

Re: Certain Federal Income Tax Consequences of the Agreement and Plan of Merger
    among Conestoga Enterprises, Inc., Infocore, Inc. and CI Merger Corporation
    ----------------------------------------------------------------------------


Gentlemen:

      We have acted as special tax counsel to Infocore, Inc., a Pennsylvania 
corporation ("Infocore"), in connection with the proposed merger (the "Merger") 
of Infocore with and into CI Merger Corporation, a Pennsylvania corporation 
("Merger Sub"), pursuant to the terms of the Agreement and Plan of Merger among 
Conestoga Enterprises, Inc., a Pennsylvania corporation ("CEI"), Infocore and 
Merger Sub dated as of March 14, 1997 (the "Merger Agreement"), and as further 
described in the Registration Statement on Form S-4 filed by CEI with the 
Securities and Exchange Commission (the "Registration Statement").

      This opinion is being rendered pursuant to your request and in accordance 
with the requirements of Form S-4 and Section 7.7 of the Merger Agreement.  All 
capitalized terms, unless otherwise specified, have the meaning assigned to them
in the Registration Statement.

      In rendering the opinion set forth below, we have relied upon certain 
written representations and covenants of CEI and of Infocore ("Representation 
Certificates"), as well as those representations set forth in Sections 3.25 and 
4.12 of the Merger Agreement. In connection with this opinion, we have examined
and are relying upon (without any independent examination or review) the truth
and accuracy, at all relevant times, of the statements, covenants,
representations and warranties contained in the following documents: (i) the
Merger Agreement, (ii) the Representation Certificates, (iii) the Registration
Statement, and (iv) such other instruments and documents as we have deemed
necessary or appropriate in order to enable us to render the opinion below.

      In our examination, we have also assumed, with your permission and without
independent investigation, that (i) original documents (including signatures) 
are authentic, documents submitted to us as copies conform to the original 
documents, and there has been (or will be by the date of the Merger) due 
execution and delivery of all documents where due execution and delivery are 
prerequisites to the effectiveness of those documents and (ii) the Merger will 
be effective under the laws of the Commonwealth of Pennsylvania.

      In rendering our opinion, we have considered the applicable provisions of 
the Internal Revenue Code of 1986, as amended (the "Code"), Treasury 
Regulations, pertinent judicial








<PAGE>
 
authorities, interpretive rulings of the Internal Revenue Service, all as in
effect as of today's date, and such other authorities as we have considered
relevant.

                                     FACTS
                                     -----

      Infocore is a diversified telecommunications services company which 
designs, installs and maintains telephone and computer systems and resells local
exchange and toll services.  CEI is a holding company, with the wholly-owned 
subsidiaries engaged in various aspects of the telecommunications business.

      Pursuant to the Merger Agreement, Infocore will merge with and into Merger
Sub.  Merger Sub will be the surviving corporation and will continue to be a 
wholly-owned subsidiary of CEI following the Merger.  By virtue of the Merger, 
the Infocore Common Shares held by any person immediately prior to the Effective
Time will become and be converted into that number of CEI Common Shares as is 
equal to the number of Infocore Common Shares held by such person multiplied by 
a fraction, the numerator of which is 200,000 and the denominator of which is 
the number of Infocore Common Shares issued and outstanding immediately prior to
the Effective Time.  Holders of Infocore Common Shares who would otherwise be 
entitled to receive a fractional share of CEI Common Stock will receive a cash 
payment in lieu of such fractional share.

                                   OPINIONS
                                   --------

      Based upon and subject to the foregoing, and based upon our reliance on 
the accuracy of the representations set forth in the Merger Agreement and 
Representation Certificates and subject to the assumptions and qualifications 
set forth herein, we are of the opinion that for federal income tax purposes:

1.   The Merger will, under current law, constitute a tax-free reorganization 
     under section 368(a) of the Code.

2.   CEI, Merger Sub, and Infocore will each be a "party to a reorganization" 
     within the meaning of section 368(b) of the Code.

As a tax-free reorganization, the Merger will have the following federal income 
tax consequences:

3.   No gain or loss will be reorganized by Infocore (or by Merger Sub by reason
     of being the successor to Infocore) by reason of the Merger.

4.   Except for any cash received in lieu of any fractional shares, no gain or
     loss will be recognized by holders of Infocore Common Shares who, pursuant
     to the Merger, receive solely CEI Common Shares in exchange for their
     Infocore Common Shares.

                                      -2-
<PAGE>
 
5.   The basis of the CEI Common Shares to be received by an Infocore
     shareholder will be the same as the basis of the Infocore Common Shares
     surrendered in exchange therefor, less any basis attributable to any
     fractional share for which cash is received.

6.   The holding period of the CEI Common Shares to be received by an Infocore
     shareholder will include the period during which the Infocore Common Shares
     surrendered in exchange therefor were held, provided that the Infocore
     Common Shares were held as a capital asset by such Infocore shareholder at
     the Effective Time.

      This opinion represents and is based upon our best judgment regarding the
application of federal income tax laws arising under the Code, existing judicial
decisions, administrative regulations and published rulings and procedures.  Our
opinion is not binding upon the Internal Revenue Service or the courts, and
there is no assurance that the Internal Revenue Service will not assert a
contrary position. Furthermore, no assurance can be given that future
legislative, judicial or administrative changes, on either a prospective or
retroactive basis, will not adversely affect the accuracy of the conclusions
stated herein. Nevertheless, we undertake no responsibility to advise you of any
new developments in the application or interpretation of the federal income tax
laws.

      No opinion is expressed as to any transaction other than the Merger as 
described in the Merger Agreement or to any transaction whatsoever, including 
the Merger, if all the transactions described in the Merger Agreement are not 
consummated in accordance with the terms of such Merger Agreement and without
waiver or breach of any material provision thereof or if all the
representations, warranties, statements and assumptions upon which we relied are
not true and accurate at all relevant times. In the event any one of the
statements, representations, warranties or assumptions upon which we have relied
to issue this opinion is incorrect, our opinion might be adversely affected and
may not be relied upon.

      This opinion is being furnished only to you in connection with the Merger 
and solely for your benefit in connection therewith and may not be used or 
relied upon for any other purpose and may not be circulated, quoted or otherwise
referred to for any purpose without our express written consent.

      Notwithstanding the foregoing, we hereby consent to the use of this 
opinion as Appendix D to the joint proxy statement/prospectus forming a part of 
the Registration Statement.  We also consent to all references to our firm in 
the Registration Statement.  In giving such opinion, we do not thereby admit 
that we are acting within the category of persons whose consent is required 
under Section 7 of the Securities Act of 1933, as amended, or the rules or 
regulations of the Securities and Exchange Commission thereunder.


                                    Very truly yours,

                                    Saul, Ewing, Remick & Saul

     Re:  Conestoga Enterprises, Inc. (the "Company) and 
          Infocore, Inc.
          ("Infocore") Registration Statement on Form S-4
          --------------------------------------------------

Gentlemen:

     We have acted as counsel for the Company, a Pennsylvania corporation, in
connection with the preparation of a registration statement on Form S-4 (the
"Registration Statement") filed with the Securities and Exchange Commission
under the Securities Act of 1933 as amended (the "Act"), relating to the
proposed Agreement and Plan of Merger dated March 14, 1997 ("Merger Agreement")
by and among the Company, Infocore and CI Merger Corporation, a wholly owned
subsidiary of the Company whereby the Company will offer up to 200,000 shares of
Company Common Stock, par value $5 per share, to the Infocore shareholders under
the Merger Agreement.  In connection thereto, we have reviewed (a) the
Registration Statement; (b) the Company's Articles of Incorporation and By-Laws;
and (c) a copy of the Merger Agreement.  Our opinion, as set forth below is
limited to the Pennsylvania Business Corporation Law of 1988, as amended.

      In our opinion, the issuance of the shares of Company Common Stock in
connection with the Merger Agreement will be legally issued, fully paid and non-
assessable.

     We hereby consent to the use of this opinion as an exhibit to the
Registration Statement.  The opinion expressed herein is for the sole benefit
of, and may be relied upon, only by the Company.

                                    Very truly yours,

                             EMPLOYMENT AGREEMENT
                             --------------------


          THIS AGREEMENT is made                         , 1997, by and between
                                 ------------------------
     CI MERGER CORPORATION (the "Company"), a Pennsylvania corporation, and
     HARRISON H. CLEMENT, JR. (the "Employee"), of
                                                   ---------------------------
               , Pennsylvania.
- ---------------
                

                                  BACKGROUND


          Pursuant to an Agreement and Plan of Merger dated March 14, 1997, by
     and among Conestoga Enterprises, Inc. ("CEI"), Infocore, Inc. ("Infocore")
     and the Company, Infocore in the near future will be merged with and into
     the Company, which will be the surviving corporation. Pursuant to such plan
     of merger (the "Plan of Merger"), as of the Effective Date of the merger
     specified therein (the "Effective Date"), the corporate name of the Company
     will become "Infocore, Inc.". The Employee is currently President and Chief
     Executive Officer of Infocore and the parties have agreed that he shall be
     employed by the Company as of the Effective Date under the terms and
     provisions contained in this Agreement.


                                   AGREEMENT


          Therefore, each intending to be legally bound hereby, the parties
     agree as follows:

          1.   Employment and Employment Duties.  Under the terms and conditions
               --------------------------------                                 
     contained in this Agreement, the Company employs the Employee as President
     and Chief Executive Officer and the Employee accepts such employment. The
     Employee's employment duties shall be those specified for the President of
     the Company in the Company's by-laws and those additional duties,
     commensurate with such position, assigned by the Board of Directors of the
     Company (the "Board"). The Employee shall report directly to the Board. The
     Employee's employment shall be on a full-time basis and he shall not be
     engaged or employed in other business activities (whether for pecuniary
     advantage or not) during the term of this Agreement, except that he shall
     be permitted to serve on the boards of directors of business or charitable
     organizations, provided such service does not materially affect the
     performance of his employment duties for the Company. The Employee shall
     discharge his employment duties in a diligent and conscientious fashion.
<PAGE>
 
          2.   Term.  The Employee's employment hereunder shall be for a period
               ----                                                            
     of two (2) years, commencing upon the Effective Date. Notwithstanding the
     foregoing: (i) the Company may terminate the Employee's employment at any
     time (A) upon fifteen (15) days prior written notice for any reason or for
     no reason, or (B) without prior notice for cause (as defined below); and
     (ii) the Employee may terminate the Employee's employment at any time
     without prior notice for any reason or for no reason. For purposes of this
     Agreement, the Employee's employment shall be deemed to have been
     terminated for cause in the event the Company terminates it as a result of:
               (a) the Employee's breach of his confidentiality obligations
     specified in Section 5;
               (b) the willful failure or refusal by the Employee to perform any
     of his material employment duties or his material obligations under this
     Agreement which shall not have ceased or been corrected within fifteen (15)
     days following a written warning from the Company; or
               (c) the commission of any act or the failure to act by the
     Employee which constitutes a crime or offense involving money or other
     property of any of the CEI Companies (as defined in Section 5) or which
     constitutes a felony in the jurisdiction involved.

          3.   Severance Compensation.

     or compelled by legal process, to refrain from disclosing such information

          6.   Covenant Not to Compete.  The Employee agrees that, in order to
               -----------------------                                        
     protect the legitimate interests and property rights of the Employer, for a

     Employee shall not:
               (a) Engage, directly or indirectly, either as owner, partner,
     agent, employee, consultant, member, or shareholder, or otherwise operate,
     control, join or participate in, lend money to, or be connected with any
     commercial enterprise or business which is engaged within the Territory (as
     defined below) in any facet of the wireless telecommunications business
     carried on by any of the CEI Companies as of the date of termination of the
     Employee's employment;
               (b) Approach, solicit, contact, or otherwise establish a business
     relationship with any customer of any of the CEI Companies or any
     prospective customer of any of the CEI Companies with whom any of such
     companies has had significant contact on or before the date of termination
     of the Employee's employment, for a purpose related to the business carried
     on by any of the CEI Companies as of the date of termination of the
     Employee's employment;
<PAGE>
 
               (c) Assist any other person, partnership, corporation, limited
     liability company, or other entity in the pursuit of the activities from

               (d) Induce by active solicitation any present or future employees
     or agents of the Company or the other CEI Companies to directly or
     indirectly engage in any competitive business or to terminate their
     employment with any of the CEI Companies.

     For purposes of this Agreement, the term "Territory" shall mean those
     geographical areas encompassed by the Reading, Pottsville, Sunbury, and
     Williamsport Basic Trading Areas, as defined by the Federal Communications
     Commission for the issuance of personal communication services licenses.
     Nothing contained in this Section 6 shall prohibit the Employee from:  (i)
     investing in and owning securities issued by any publicly-held company
     which are traded on any recognized securities exchange or in the over-the-
     counter market; or (ii) accepting employment, after termination of his
     employment with the Company, with a customer of the Company which is not a
     significant customer.

          7.   Equitable Relief.  The Employee recognizes and agrees that, in
               ----------------                                              
     the event of a breach or threatened breach of his covenants and obligations
     contained in Section 5 and/or Section 6 of this Agreement, the Company will
     suffer irreparable harm and damage, that such harm and damage may be
     extremely difficult or impossible to quantify, and that therefore the
     Company shall be entitled to injunctive relief. Nothing contained herein,
     however, shall be construed as precluding the Company from pursuing any
     other remedies available to it for such breach or threatened breach,
     including the recovery of damages at law.

          8.   Restrictions Excessive.  In the event the restrictions imposed by
               ----------------------                                           
     the covenant contained in Section 6 are deemed by any court having
     jurisdiction to be unreasonable or otherwise unenforceable by reason of
     their duration, territory or the scope of the activities prohibited, it is
     agreed by the parties that such court may construe and enforce this
     Agreement by reducing the time period, territory, or scope of activities to
     an extent which such court deems to be reasonable and enforceable.

          9.   Severability.  If any provision or provisions of this Agreement
               ------------                                                   
     shall be deemed to contravene or be invalid under the laws of any
     jurisdiction where this Agreement is in force, the parties agree that such
<PAGE>
 
     contravention or invalidity shall not invalidate the entire Agreement, but
     it shall be construed as not containing the particular provision or
     provisions held to be invalid and the rights and obligations of the parties
     shall be construed and enforced accordingly.

          10.  Miscellaneous.
               ------------- 
               (a) This Agreement shall be construed, interpreted and enforced
     in accordance with the laws (but not the law of conflict of laws) of the
     Commonwealth of Pennsylvania.
               (b) This Agreement and its provisions shall be binding upon and
     inure to the benefit of the respective legal representatives, successors,
     heirs, and permitted assigns of the parties.  The Employee shall not assign
     any of his rights nor delegate any of his duties under this Agreement
     without the prior written consent of the Company.
               (c) This Agreement constitutes the entire Agreement between the
     parties and supersedes all prior negotiations, understandings and
     agreements of any nature whatsoever, whether oral or written, with respect
     to the subject matter hereof.  No amendment, waiver or discharge of any
     provision of this Agreement shall be effective against any party, unless
     that party shall have consented thereto in writing.
               (d) The headings to the sections of this Agreement are inserted
     only for convenience of reference and are not intended, nor shall they be
     construed, to modify, define, limit or expand the intent of the parties as
     expressed in this Agreement.

          IN WITNESS WHEREOF, the parties have executed this Agreement the day
     and year first above written.

Williamsport Basic Trading Areas, as defined by the Federal Communications
Commission for the issuance of personal communication services licenses. Nothing
contained in this Section 6 shall prohibit the Employee from: (i) investing in
and owning securities issued by any publicly-held company which are traded on
any recognized securities exchange or in the over-the-counter market; or (ii)
accepting employment, after termination of his employment with the Company, with
a customer of the Company which is not a significant customer.

          7.   Equitable Relief.  The Employee recognizes and agrees that, in
               ----------------                                              
the event of a breach or threatened breach of his covenants and obligations
contained in Section 5 and/or Section 6 of this Agreement, the Company will
suffer irreparable harm and damage, that such harm and damage may be
extremely difficult or impossible to quantify, and that therefore the
Company shall be entitled to injunctive relief.  Nothing contained herein,
however, shall be construed as precluding the Company from pursuing any
other remedies available to it for such breach or threatened breach,
including the recovery of damages at law.

          8.   Restrictions Excessive.  In the event the restrictions imposed by
               ----------------------                                           
the covenant contained in Section 6 are deemed by any court having jurisdiction
to be unreasonable or otherwise unenforceable by reason of their duration,
territory or the scope of the activities prohibited, it is agreed by the parties
that such court may construe and enforce this Agreement by reducing the time
period, territory, or scope of activities to an extent which such court deems to
be reasonable and enforceable.

          9.   Severability.  If any provision or provisions of this Agreement
               ------------                                                   
shall be deemed to contravene or be invalid under the laws of any
jurisdiction where this Agreement is in force, the parties agree that such
<PAGE>
 
contravention or invalidity shall not invalidate the entire Agreement, but it
shall be construed as not containing the particular provision or provisions held
to be invalid and the rights and obligations of the parties shall be construed
and enforced accordingly.

          10.  Miscellaneous.
               ------------- 

               (a) This Agreement shall be construed, interpreted and enforced
in accordance with the laws (but not the law of conflict of laws) of the
Commonwealth of Pennsylvania.

               (b) This Agreement and its provisions shall be binding upon and
inure to the benefit of the respective legal representatives, successors, heirs,
and permitted assigns of the parties. The Employee shall not assign any of his
rights nor delegate any of his duties under this Agreement without the prior
written consent of the Company.

               (c) This Agreement constitutes the entire Agreement between the
parties and supersedes all prior negotiations, understandings and agreements of
any nature whatsoever, whether oral or written, with respect to the subject
matter hereof. No amendment, waiver or discharge of any provision of this
Agreement shall be effective against any party, unless that party shall have
consented thereto in writing.

               (d) The headings to the sections of this Agreement are inserted
only for convenience of reference and are not intended, nor shall they be
construed, to modify, define, limit or expand the intent of the parties as
expressed in this Agreement.

        IN WITNESS WHEREOF, the parties have executed this Agreement the day
and year first above written.

                                 INSTRUCTIONS

                   Forming Part of the Terms and Conditions
                         of this Letter of Transmittal


     1.   Use of Letter of Transmittal.  This Letter of Transmittal, properly
filled in, dated and signed, together with your surrendered Infocore stock
certificates (the "Surrendered Certificates") and any other documents required
by these Instructions, should be sent by mail or delivered by hand to the
Exchange Agent, in each case at the appropriate address as set forth above.  The
method of delivery of all documents is at the option and risk of the
shareholder, but if delivery is by mail, registered mail with return receipt
requested, properly insured, is recommended.  A return envelope is enclosed for
your convenience.

     2.   Signatures.  If you wish your CEI Common Stock certificate to be
issued in your name, this Letter of Transmittal must be signed by you or on your
behalf as the registered holder(s) of the Surrendered Certificates.  In the case
of joint tenants, both must sign.  If the Surrendered Certificates are
registered in different forms of the name of any person signing this Letter of
Transmittal (e.g., "John Smith" on one certificate and "J. Smith" on another),
it will be necessary for such person either to sign this Letter of Transmittal
in each way in which the certificates are registered or to sign as many Letters
of Transmittal as there are different forms of name.  If the Surrendered
Certificates have been transferred or assigned, please follow Instruction 4.

     3.   Issuance of CEI Common Stock Certificate in Same Name.  If the CEI
Common Stock certificate is to be issued in the name of the registered holder as
shown on the Surrendered Certificates, the Surrendered Certificates need not be
endorsed.

     4.   Issuance of CEI Common Stock Certificate in Different Names.  If the
CEI Common Stock Certificate is to be issued in the name of someone other than
the registered owner of the Surrendered Certificates, please be guided by the
following:

          a.   Endorsement and Guarantee.  The Surrendered Certificates must be
               -------------------------                                       
properly endorsed (or accompanied by appropriate stock powers properly executed
by the registered holder of such certificates) to the person who is to receive
the CEI Common Stock certificate.  The signature of the registered holder on the
endorsement or stock powers must correspond with the name as written upon the
face of the Surrendered Certificates in every particular and must be guaranteed
by a commercial bank (not a savings bank or savings and loan association) or
trust company in the United States or by a member firm of any national
securities exchange or of the National Association of Securities Dealers, Inc.
("Qualified Guarantor").

                                      -5-
<PAGE>
 
          b.   Transferee's Signature.  This Letter of Transmittal must be
               ----------------------                                     
signed by the transferee or by his agent, and should not be signed by the
transferor.  The signature of such transferee or agent must be guaranteed by a
Qualified Guarantor as defined in Instruction 4(a).

          c.   Transfer Taxes.  In the event that any transfer or other taxes
               --------------                                                
become payable by reason of the issuance of any CEI Common Stock certificate in
any name other than that of the registered holder, such transferee must pay such
tax to the Exchange Agent or CEI or must establish to the satisfaction of CEI
that such tax has been paid or is not payable.

          d.   Correction of or Change in Name.  For a correction of name or for
               -------------------------------                                  
a change in name which does not involve a change of ownership, proceed as
follows:  for a change in name by marriage, etc., the Surrendered Certificates
should be endorsed, e.g., "Mary Doe, now by marriage Mrs. Mary Jones," with the
signature guaranteed by a Qualified Guarantor as described in Instruction 4(a).
For a correction in name, the Surrendered Certificates should be endorsed, e.g.,
"James E. Brown, incorrectly inscribed as J.E. Brown" with the signature
guaranteed by a Qualified Guarantor as described in Instruction 4(a).

     5.   31% Backup Withholding. In order to avoid "backup withholding" of
Federal income tax on the cash received, in lieu of a fractional share of CEI
Common Stock, a stockholder must, unless an exemption applies, provide the
Exchange Agent with his correct taxpayer identification number ("TIN") on the
Form W-9 accompanying this Letter of Transmittal and certify, under penalties of
perjury, that such number is correct. If the correct TIN is not provided, a $50
penalty may be imposed by the Internal Revenue Service and payments made in lieu
of a fractional share of CEI Common Stock may be subject to backup withholding
of 31%.

          Backup withholding is not an additional Federal income tax.  Rather,
the Federal income tax liability of persons subject to backup withholding will
be reduced by the amount of such tax withheld.  If backup withholding results in
an overpayment of taxes, a refund may be obtained from the Internal Revenue
Service.

          The TIN that must be provided on the Form W-9 is that of the
registered holder of the Surrendered Certificates or of the last transferee
appearing on the transfers attached to or endorsed on the Surrendered
Certificates.  The TIN for an individual is his social security number.

          Exempt persons (including, among others, corporations) are not subject
to backup withholdings and should indicate their exempt status on Form W-9.  A
foreign person may qualify as an exempt person by submitting a statement, signed
under penalties of perjury, certifying such person's foreign status.  Such
statements can be obtained from the Exchange Agent.  A 

                                      -6-
<PAGE>
 
stockholder should consult his tax advisor as to his qualification for exemption
from backup withholdings and the procedure for obtaining such exemption.

          For additional guidance, see the enclosed Form W-9.

     6.   Supporting Evidence.  In case any Letter of Transmittal, certificate,
endorsement or stock power is executed by an agent, attorney, administrator,
executor, guardian, trustee, or in any other fiduciary or representative
capacity, or by an officer of a corporation on behalf of the corporation, there
should be submitted documentary evidence of appointment and authority to act in
such capacity (including court orders and corporate resolutions where necessary)
as well as evidence of the authority of the person making such execution to
assign, sell or transfer shares.  Such documentary evidence of authority must be
in a form satisfactory to the Exchange Agent and submitted with the Letter of
Transmittal, Surrendered Certificates and/or stock power.

     7.   Cash Payment for Fractional Shares.  CEI will not issue any fractional
shares of CEI Common Stock in connection with the Merger.  Instead, CEI will pay
holders of a fractional share of CEI Common Stock an amount in cash (rounded to
the nearest whole cent) equal to (i) $_____ (the per share market value of CEI
Common Stock as determined pursuant to the Merger Agreement on the effective
date of the merger) times (ii) the fractional share to which such holder would
otherwise be entitled.

     8.   Additional Copies.  Additional copies of this Letter of Transmittal or
the Form W-9 may be obtained from the Exchange Agent.

     9.   Multiple Certificates.  If, for tax purposes, a holder of Infocore
Common Stock wished to maintain the separate tax bases and holding period of
certain blocks of Infocore Common Stock held by such holder, or otherwise have
multiple certificates issued for the CEI Common Stock, explicit instructions to
the Exchange Agent should be provided.

     YOU ARE URGED TO COMPLETE AND RETURN THIS LETTER OF TRANSMITTAL PROMPTLY.
ANY DIVIDENDS AND OTHER DISTRIBUTIONS PAYABLE TO HOLDERS OF RECORD OF SHARES OF
CEI COMMON STOCK AFTER THE MERGER WILL NOT BE DELIVERED TO YOU BUT WILL BE HELD
(WITHOUT INTEREST) UNTIL YOU SURRENDER YOUR INFOCORE CERTIFICATE(S).

                                      -7-
