[LETTERHEAD OF PARKER/HUNTER INCORPORATED]

September 30, 1998

The Board of Directors
Carnegie Group, Inc.

Pittsburgh, PA 15222

Gentlemen:

You have requested our opinion as to the fairness, from a financial point of 
view, to the holders of common stock, par value $.01 per share (the "Common 
Stock"), of Carnegie Group, Inc. ("Carnegie" or the "Company") of the 
consideration to be received by such holders in connection with the Agreement 
and Plan of Merger (the "Agreement") by and among Logica Inc., Logica 
Acquisition Corp. and Carnegie.  The Agreement provides for the commencement of
a tender offer ("Offer") to purchase all shares of Common Stock of the Company
at a price of $5.00 per share in cash for each share of Common Stock of the
Company.

Parker/Hunter Incorporated, as part of its investment banking business, is 
regularly engaged in the valuation of businesses and their securities in 
connection with mergers and acquisitions, negotiated underwritings, the purchase
and sale of listed and unlisted securities, private placements and valuations 
for estate, corporate and other purposes. Further, we have provided investment 
banking services to the Company in the past and have received customary fees for
such services.

In connection with our opinion, we have reviewed, among other things, the 
following: (i) the Agreement dated as of September 30, 1998; (ii) the Company's 
audited financial statements as of December 31, 1997 and for the five prior 
fiscal years then ended and its unaudited financial statements as of June 30, 
1998 and June 30, 1997 and for the six month periods then ended; (iii) certain 
other publicly available and internal information, primarily financial in 
nature, including financial projections for the Company prepared by the 
management of the Company; (iv) certain publicly available information 
concerning the trading of, and the trading markets for, the Common Stock, (v) 
the nature and financial terms of certain recent business combinations which we 
believe to be relevant; and (vi) certain publicly available information 
regarding companies that we believe to be comparable to the Company as well as 
trading market information for certain of such other companies' securities. We 
have also met with certain senior officers and directors of the Company to 
discuss the foregoing as well as the operations, financial condition, history 
and prospects of the Company and other matters we believe to be relevant. We 
have taken into account our assesment of general economic, market and financial 
conditions and our experience in securities valuation generally. We have also

                                                            Carnegie Group, Inc.
                                                              September 30, 1998
                                                                          Page 2

considered such other information, financial studies, analyses, investigations
and financial, economic, market and trading criteria that we deemed relevant. We
have not been requested to and did not solicit third party indications of
interest in acquiring all or any part of the Company.

In rendering this opinion, we relied, without independent verification, on the
accuracy and completeness of all financial and other information that was
publicly available or furnished or otherwise communicated to us by the Company.
We have not made an independent evaluation or appraisal of the assets or
liabilities of the Company, nor have we been furnished with any such evaluations
or appraisals. With respect to the Company's financial projections, we have
assumed that they have been reasonably prepared on bases reflecting the best
currently available estimates and good faith judgments of the Company's
management and we express no opinion with respect to such projections or the
assumptions on which they are based. Our opinion is necessarily based upon the
business, market, monetary, economic, and other conditions as they exist on, and
can be evaluated as of, the date of this letter and does not predict or take
into account any changes which may occur, or information which may become
available, after the date hereof. Further, our opinion does not address the
relative merits of the Offer and any other potential transactions or business
strategies considered by the Board of Directors of the Company, and does not
constitute a recommendation to any holder of the Common Stock of the Company as
to whether such holder should tender its shares in the Offer or as to how such
holder should vote with respect to the merger.

In the ordinary course of our business, we may actively trade the equity 
securities of the Company for our own account and for the accounts of our 
customers and, accordingly, may at any time hold a long or short position in 
such securities.

Based upon and subject to the foregoing, it is our opinion that, as of the date
hereof, the consideration to be received by the holders of Common Stock pursuant
to the Agreement is fair to such holders from a financial point of view.

Very truly yours,

PARKER/HUNTER INCORPORATED
