                                December 9, 1994      



Dear Stockholders:
    
     We are pleased to invite you to a Special Meeting of Stockholders of
InterCAP Graphics Systems, Inc., a Delaware corporation ("InterCAP"), to be held
on January 11, 1995, at 8:00 a.m., local time (the "Meeting"), at the offices
of InterCAP, 116 Defense Highway, Suite 400, Annapolis, Maryland 21401. The
purpose of the meeting is to obtain your approval of the acquisition of InterCAP
by Intergraph Corporation, a Delaware corporation ("Intergraph").      
    
     On September 30, 1994, InterCAP signed an Agreement and Plan of
Reorganization (as subsequently amended as of December 7, 1994, the
"Reorganization Agreement") with Intergraph and Intergraph DC Corporation
Subsidiary 7, a Delaware corporation and a wholly owned subsidiary of Intergraph
("Intergraph Sub"), providing for the merger of Intergraph Sub with and into
InterCAP (the "Merger"). As a result of the Merger, InterCAP would become a
wholly owned subsidiary of Intergraph. Pursuant to the terms of the
Reorganization Agreement, each outstanding share of InterCAP Common Stock,
InterCAP Series B Preferred Stock, and InterCAP Series C Preferred Stock would
be converted into a fraction of a share of Intergraph Common Stock, par value
$.10 per share (the "Intergraph Common Stock"), having a value of $0.90975693,
and each share of InterCAP Series A Preferred Stock would be converted into a
fraction of a share of Intergraph Common Stock having a value of $1.475. At the
Meeting, you will be asked to approve the Reorganization Agreement and the
transactions contemplated thereby.       

     You will also be asked at the Meeting and in connection with the Merger, to
approve an amendment to the Certificate of Incorporation of InterCAP (the
"Charter Amendment").  In 1993, the stockholders of InterCAP approved an
amendment to the Certificate of Incorporation of InterCAP that reduced the
liquidation preference of the InterCAP Series A Preferred Stock to $1.475 per
share plus (if the effective date of the liquidation was after October 1, 1994)
an amount equal to one-half of all accrued but unpaid dividends thereon (the
"Series A Liquidation Preference").  To facilitate the Merger, the holders of
the InterCAP Series A Preferred Stock have agreed to postpone the increase in
the Series A Liquidation Preference to January 15, 1995 and thereby postpone any
further increase in the difference between the value of the InterCAP Series A
Preferred Stock and the remaining classes of InterCAP Stock.  The Charter
Amendment to be voted on at the Meeting would make this change to the
Certificate of Incorporation of InterCAP.

     After careful consideration, your Board of Directors has unanimously
adopted and approved the Charter Amendment, the Reorganization Agreement and the
transactions
<PAGE>
 
contemplated thereby (collectively, the "Proposed Transactions").  The Board
believes that the Proposed Transactions are advisable and in the best interests
of InterCAP and its stockholders and recommends that you vote "FOR" the proposal
to adopt and approve the Charter Amendment and "FOR" the adoption and approval
of the Reorganization Agreement and the transactions contemplated thereby.

     The accompanying Prospectus/Proxy Statement provides a detailed description
of the Proposed Transactions. We urge you to give careful consideration to the
Prospectus/Proxy Statement.

     Approval of the Proposed Transactions requires (i) in the case of the
Charter Amendment, the affirmative vote of (a) a majority of the outstanding
shares of InterCAP Common Stock and InterCAP Preferred Stock, voting as a single
class; (b) a majority of the outstanding shares of InterCAP Series A Preferred
Stock, voting separately; (c) a majority of the outstanding shares of InterCAP
Series A Preferred Stock, and InterCAP Series B Preferred Stock, voting as a
single class; and (d) a majority of the outstanding InterCAP Series C Preferred
Stock, voting separately; and (ii) in the case of the Reorganization Agreement
and the transactions contemplated thereby, the affirmative vote of (a) at least
66.67% of the outstanding shares of InterCAP Common Stock and the InterCAP
Preferred Stock, voting as a single class, and (b) a majority of the outstanding
shares of InterCAP Series A Preferred Stock and InterCAP Series B Preferred
Stock, voting as a single class.

     To ensure that your shares are represented, please vote, date, sign and
mail the enclosed proxy in the envelope provided, whether or not you expect to
be present at the Meeting.

                                  Sincerely,

     The Merger and Related Transactions

          Aggregate Merger Consideration

          Pursuant to the Reorganization Agreement, Intergraph will pay or
     furnish total consideration having a value (based on the Share
     Determination Market Price, as hereinafter defined) of $7.5 million for the
     entire equity interest of InterCAP.  Such consideration will be paid or
     furnished (i) by the conversion of outstanding InterCAP Options (as defined
     herein) into options to acquire Intergraph Common Stock such that the
     aggregate value of all options (based upon the difference between the
     exchange ratio per share of InterCAP Common Stock and the exercise price
     per share of such options) so converted at the time the Merger is
     consummated will be equal to $1,021,573.65 (the "Aggregate Assumed Option
     Spread"), (ii) by the issuance of shares of Intergraph Common Stock (and
     cash payments in respect of fractional shares) in an amount equal to $7.5
     million minus the Aggregate Assumed Option  Spread (the amount specified in
     this clause (ii) is referred to as the "Closing Merger Consideration").
     The Closing Merger Consideration shall be allocated among the classes of
     InterCAP Stock (as defined herein) according to the exchange ratios
     described elsewhere in this summary.  See "The Reorganization Agreement--
     Manner and Basis of Converting InterCAP Stock."  The precise number of
     shares of Intergraph Common Stock issued to each stockholder of InterCAP
     shall be determined prior to consummation of the Merger based on the
     applicable exchange ratio and the Share Determination Market Price.  It is
     expected that, upon consummation of the Merger, the holders of InterCAP
     Stock will receive shares of Intergraph Common Stock representing
     approximately 1.57% of the Intergraph Common Stock outstanding as of such
     time.

          Reasons for the Merger

          In the discussions that led to the execution of the Reorganization
     Agreement, Intergraph and InterCAP identified a number of potential joint
     benefits resulting from the Merger, including expanded marketing,
     distribution and technical opportunities for the two companies, a more
     diversified intellectual property base, and the benefits of combining the
     complementary products of the two firms.  In addition, Intergraph believes
     that the acquisition of InterCAP will provide Intergraph with both
     strategic and technical advantages by expanding Intergraph's product mix
     and customer base.  The InterCAP Board of Directors believes the Merger
     will enhance InterCAP's marketing and distribution capabilities as well as
     its financial and technical resources for product development.  In
     addition, the Merger affords InterCAP investors with liquidity

                                      -4-
<PAGE>
 
     for their InterCAP Common Stock and InterCAP Preferred Stock (collectively
     "InterCAP Stock").  See "The Merger and Related Transactions."

          Recommendation of InterCAP's Board of Directors
         
          The Board of Directors of InterCAP has unanimously adopted and
     approved the Charter Amendment, the Reorganization Agreement and the
     transactions contemplated thereby (collectively, the "Proposed
     Transactions").  The Board believes that the Proposed Transactions are
     advisable and in the best interests of InterCAP and its stockholders and
     recommends that InterCAP stockholders vote for approval and adoption of the
     Proposed Transactions.  The Board's recommendation is based on its
     collective subjective analysis of the Proposed Transactions and is not
     supported by an opinion from an investment banking firm as to the fairness
     of the Proposed Transactions, from a financial point of view, to InterCAP's
     stockholders.  See "The Merger and Related Transactions--InterCAP's Reasons
     for the Merger."  In making its recommendation, one of the many factors
     considered by the Board was that the Merger provided InterCAP stockholders
     with the opportunity to make a tax-free exchange of InterCAP Stock for
     Intergraph Common Stock.  The Board was aware, however, that counsel's
     opinion on certain aspects of the tax treatment of the Merger would
     recognize that the issue was not free from doubt and subject to some legal
     uncertainty.  See "The Merger and Related Transactions--InterCAP's Reasons
     for the Merger" and "--Certain Federal Income Tax Considerations."      

          Related Agreements

          Preferred Stock Agreement.  Pursuant to the Preferred Stock Agreement
          -------------------------                                            
     entered into between InterCAP and certain stockholders of InterCAP as of
     September 30, 1994 (the "Preferred Stock Agreement"), such stockholders
     have agreed, among other things, (i) to vote all of their shares of
     InterCAP Stock in favor of approving the Charter Amendment; (ii) in the
     case of holders of InterCAP Series A Preferred Stock, to elect to take the
     liquidation preference of $1.475 per share of InterCAP Series A Preferred
     Stock; (iii) in the case of the remaining classes of InterCAP Preferred
     Stock, to elect to convert the InterCAP Series B Preferred Stock and
     InterCAP Series C Preferred Stock into InterCAP Common Stock prior to the
     consummation of the Merger; and (iv) that the receipt of a fraction of a
     share of Intergraph Common Stock with a value of $1.475 per share of
     InterCAP Series A Preferred Stock and the receipt of a fraction of a share
     of Intergraph Common Stock with a value of $0.90975693 per share of
     InterCAP Common Stock upon conversion of the InterCAP Series B Preferred
     Stock and the InterCAP Series C Preferred Stock shall be in complete and
     full satisfaction of all

                                      -5-
<PAGE>
 
     rights and preferences attendant to such Preferred Stock.  Consummation of
     the Merger is conditioned on approval of the Charter Amendment contemplated
     by the Preferred Stock Agreement.  The stockholders who are parties to the
     Preferred Stock Agreement have agreed to vote in favor of the Charter
     Amendment, but have not agreed to vote in favor of, and are free to vote
     against or not vote at all with respect to the Merger.  See "The Merger and
     Related Transactions--Preferred Stock Agreement" and "Stockholder Approval
     of the Reorganization Agreement, the Merger and the Charter Amendment."

          Escrow Agreement.  Under the terms of the Reorganization Agreement and
          ----------------                                                      
     the Escrow Agreement (the "Escrow Agreement") to be entered into among
     Intergraph, the Stockholders' Committee (as defined in the Reorganization
     Agreement) and an escrow agent to be selected by Intergraph and InterCAP
     (the "Escrow Agent"), at the consummation of the Merger, Intergraph will
     deliver to the Escrow Agent one or more certificates representing a portion
     of the shares of Intergraph Common Stock to be issued to the InterCAP
     stockholders, equal in the aggregate to fifteen percent (15%) of the
     aggregate shares of Intergraph Common Stock to be issued to all InterCAP
     stockholders in the Merger (such shares being referred to herein as the
     "Escrow Shares").  The Escrow Shares will secure the InterCAP stockholders'
     indemnification obligations with respect to the representations and
     warranties made by InterCAP in the Reorganization Agreement.  In the event
     a valid indemnification claim is timely asserted by Intergraph, some or all
     of the Escrow Shares will be forfeited by the InterCAP stockholders and
     returned to Intergraph.  The Escrow Shares will remain in escrow until the
     90th day after the consummation of the Merger, at which time the Escrow
     Agent will distribute the remaining Escrow Shares which are not then
     subject to pending claims by indemnified person(s) under the Escrow
     Agreement, if any, to the InterCAP stockholders in the manner described in
     the Escrow Agreement.  See "The Merger and Related Transactions--Escrow
     Agreement."

          InterCAP Incentive Stock Option Agreements

          Under the terms of certain employee stock option agreements (the "ISO
     Agreements") entered into from time to time between InterCAP and various
     employees (each an "Optionee"), InterCAP has granted options denominated as
     incentive stock options to each Optionee in consideration of the continued
     employment service of the Optionee (the "ISO's").  The options are
     authorized by the InterCAP 1989 Stock Option Plan (the "InterCAP Option
     Plan").  Intergraph will assume such options in connection with the Merger,
     following adjustment of the exercise price and number of shares covered
     thereby.  See "The Merger and Related Transactions--Options Outstanding
     Prior to the Merger."

                                      -6-
<PAGE>
 
          InterCAP Nonqualified Stock Option Agreements

          Under the terms of Nonqualified Stock Option Agreements between
     InterCAP and various Optionees, InterCAP has granted nonqualified stock
     options to each Optionee in recognition of such Optionee's past service to
     InterCAP and to induce the Optionee to remain an employee of InterCAP
     following its merger with Intergraph Sub (the "NQSO's").  The options are
     authorized by the InterCAP 1994 Nonqualified Stock Option Program (the
     "InterCAP Option Program").  Intergraph will assume such options in
     connection with the Merger, following adjustment of the exercise price and
     number of shares covered thereby.  See "The Merger and Related
     Transactions--Options Outstanding Prior to the Merger."

          Certain Federal Income Tax Considerations

          Counsel to InterCAP and counsel to Intergraph have each provided an
     opinion that the Merger will be treated as a tax-free reorganization for
     federal income tax purposes, so that no gain or loss will be recognized by
     InterCAP stockholders on the exchange of InterCAP Stock for Intergraph
     Common Stock, except to the extent that InterCAP stockholders receive cash
     in lieu of fractional shares in the exchange.  Such opinions are based upon
     certain assumptions and subject to certain qualifications noted therein.
     Moreover, the opinions on whether the Merger satisfies the "continuity of
     proprietary interest" requirement of a tax-free reorganization express that
     the issue is not free from doubt and is subject to some legal uncertainty.
     In addition, such opinions will assume that at the time the Merger is
     consummated, the InterCAP stockholders will furnish InterCAP and Intergraph
     with certificates confirming that the InterCAP stockholders, as a group, do
     not then have a present intention to sell, transfer, pledge or otherwise
     dispose of more than 50% of the shares of Intergraph Common Stock to be
     received in the Merger.  The Reorganization Agreement does not require the
     parties to obtain a ruling from the Internal Revenue Service as to the tax
     consequences of the Merger.  INTERCAP STOCKHOLDERS ARE URGED TO CONSULT
     THEIR OWN TAX ADVISORS REGARDING SUCH TAX CONSEQUENCES.  See "The Merger
     and Related Transactions--Certain Federal Income Tax Considerations."

          Accounting Treatment

          The Merger is expected to be treated as a purchase for financial
     accounting purposes.  See "The Merger and Related Transactions--Accounting
     Treatment."

                                      -7-

          Governmental and Regulatory Approvals

          Intergraph and InterCAP are aware of no governmental or regulatory
     approvals required for consummation of the Merger, other than compliance
     with the Securities Act and applicable state securities and "blue sky"
     laws.

          Dissenters' Rights

          Under the Delaware Act (as hereinafter defined), record holders of
     InterCAP Stock who or which, prior to the vote at the Meeting, properly
     demand appraisal and vote against or abstain from voting on the
     Reorganization Agreement and the Merger have the right to obtain a cash
     payment for the "fair value" of their shares (excluding any element of
     value arising from the accomplishment or expectation of the Merger).  In
     order to exercise such rights, holders of InterCAP Stock must comply with
     the procedural requirements of Section 262 of the Delaware Act, a
     description of which is provided in "The Merger and Related Transactions--
     Dissenters' Rights" and the full text of which is attached to this
     Prospectus/Proxy Statement as Appendix C.  Such "fair value" would be
     determined in judicial proceedings, the result of which cannot be
     predicted.  Failure to take any of the steps required under Section 262 on
     a timely basis may result in the loss of appraisal rights.  Intergraph's
     obligation to consummate the Merger is subject to the condition that the
     holders of no more than 5% of the shares of InterCAP Stock shall have
     perfected their dissenters' rights.

          Exchange of Certificates

          The exchange of certificates evidencing shares of InterCAP Stock for
     certificates evidencing shares of Intergraph Common Stock will be made upon
     surrender of InterCAP share certificates to the exchange agent appointed by
     Intergraph to act in such capacity with respect to the Merger (the
     "Exchange Agent").  As soon as practicable after the Effective Date, the
     Exchange Agent will mail to each holder of record of InterCAP Stock a
     letter of transmittal and written instructions for use in effecting the
     surrender of InterCAP share certificates (collectively, the "Letter of
     Transmittal").  CERTIFICATES SHOULD NOT BE SURRENDERED FOR EXCHANGE BEFORE
     THE STOCKHOLDERS OF INTERCAP RECEIVE THE LETTER OF TRANSMITTAL FROM THE
     EXCHANGE AGENT FOLLOWING CONSUMMATION OF THE MERGER.

     The Reorganization Agreement
         
          If the Reorganization Agreement and the Merger are approved and
     adopted by the stockholders of InterCAP and the other conditions to the
     Merger are satisfied or waived, the Merger will become effective upon the
     filing by InterCAP of a certificate of merger with the Secretary of State
     of the State of Delaware, in the manner provided under Section 251 of the
     Delaware Act (the date of such filing being referred to herein as the
     "Effective Date").  Assuming all conditions to the Merger are met or waived
     prior thereto, it is anticipated that the Effective Date will occur on or
     about January 12, 1995.      

          General

          Effects of the Merger.  Upon consummation of the Merger, Intergraph
          ---------------------                                              
     Sub will be merged with and into InterCAP, with InterCAP surviving the
     Merger and becoming a wholly owned subsidiary of Intergraph (the "Surviving
     Corporation").  The officers and directors of Intergraph Sub immediately
     prior to the Merger will be the officers and directors of the surviving
     corporation in the Merger.  The stockholders of InterCAP will become
     stockholders of Intergraph (as described below), and their rights will be
     governed by Intergraph's Certificate of Incorporation and Restated By-laws.

          Conversion of Shares of InterCAP Stock.  Upon consummation of the
          --------------------------------------                           
     Merger, (a) each then outstanding share of InterCAP Common Stock will
     automatically be converted into the right to receive a fraction of a share
     of Intergraph Common Stock having a value of $0.90975693; (b) each then
     outstanding share of InterCAP Preferred Stock will automatically be
     converted into a fraction of a share of Intergraph Common Stock as follows:
     (i) each share of InterCAP Series A Preferred Stock will be automatically
     converted into the right to receive a fraction of a share of Intergraph
     Common Stock having a value of $1.475; (ii) each share of InterCAP Series B
     Preferred Stock, if any, will be automatically converted into the right to
     receive a fraction of a share of Intergraph Common Stock having a value of
     $0.90975693; and (iii) each share of InterCAP Series C Preferred Stock, if
     any, will be automatically converted into the right to receive a fraction
     of a share of Intergraph Common Stock having a value of $0.90975693.  Cash
     will be paid in lieu of issuing fractional shares.  Each share of
     Intergraph Common Stock will be valued at the average closing sale price of
     Intergraph Common Stock as reported by NASDAQ for the ten (10) days of
     trading immediately preceding the fifth business day prior to the Effective
     Date (the "Share Determination Market Price").

          Assumption of Options.  Upon consummation of the Merger, each
          ---------------------                                        
     outstanding InterCAP option denominated as an ISO and each outstanding NQSO
     (each, an "InterCAP Option") will be assumed by Intergraph and
     automatically converted into an option to purchase a number of shares of
     Intergraph Common Stock determined by multiplying the number of shares of
     InterCAP Common Stock subject to the InterCAP Option by the fraction
     resulting from dividing $0.90975693 by the Share Determination Market Price
     (the "Option Conversion Fraction").  The exercise price of each assumed
     option (an "Assumed Option") will be equal to the exercise price of the
     InterCAP Option at the time the Merger is consummated divided by the Option
     Conversion Fraction.  The other terms of the Assumed Options will remain
     unchanged, and, as a result, the ISO's will be fully vested by virtue of
     the Merger and the NQSO's will be 50% vested upon the Effective Date, with
     an additional 25% to vest on the two succeeding anniversaries of the
     Effective Date so long as the Optionee remains an employee of the Surviving
     Corporation.  To avoid fractional shares, the number of shares of
     Intergraph Common Stock subject to an Assumed Option will be rounded up to
     the nearest whole share.  Prior to the Effective Date, Intergraph intends
     to file Registration Statements on Form S-8 with the SEC with respect to
     the issuance of shares of Intergraph Common Stock upon exercise of the
     Assumed Options.

          At the Record Date, the number of shares of InterCAP Common Stock
     subject to ISO's and NQSO's were 935,062 and 391,562, respectively.

          Conditions to the Merger

          In addition to the requirement that the approval by InterCAP's
     stockholders be received, consummation of the Merger is subject to a number
     of other conditions that, if not satisfied or waived, may cause the Merger
     not to be consummated and the Reorganization Agreement to be terminated.
     Intergraph's obligation to consummate the Merger is conditioned on, among
     other things, the accuracy of InterCAP's representations, the absence of a
     material adverse change in InterCAP's business, InterCAP's performance of
     its covenants and each party's receipt of favorable legal opinions
     (including an opinion to the effect that the Merger will be treated for
     federal income tax purposes as a tax-free reorganization).  See "The
     Reorganization Agreement--Conditions to the Merger."

          Representations and Covenants

          In the Reorganization Agreement, InterCAP made a number of
     representations regarding its capital structure, operations, financial
     condition and other matters, including its authority to enter into the
     Reorganization Agreement

                                      -10-
<PAGE>
 
     and to consummate the Merger.  InterCAP covenanted, among other things,
     that, until the consummation of the Merger or the termination of the
     Reorganization Agreement, it will operate its business in the normal and
     ordinary course, use its best efforts to maintain its business and refrain
     from taking certain actions without Intergraph's written consent.  In
     addition, each party agreed to use its best efforts to consummate the
     Merger.  InterCAP has agreed not to initiate, solicit or facilitate any
     proposals that compete with the Merger, and that, if the Board of Directors
     of InterCAP receives an unsolicited proposal from a third party, it may
     pursue or accept such proposal, but only upon certification in writing to
     Intergraph that the Board of Directors of InterCAP has determined that the
     proposal or offer is more favorable to InterCAP and its stockholders and
     that the Board of Directors of InterCAP has determined, with the advice of
     counsel, that it must accept such proposal or offer in the exercise of its
     fiduciary duties.  See "The Reorganization Agreement--Representations and
     Warranties; Certain Covenants."  Moreover, if such action results in
     termination of the Reorganization Agreement, InterCAP must pay a
     termination fee to Intergraph.  See "The Reorganization Agreement--
     Termination Fee."

          Indemnification

          By virtue of their adoption and approval of the Reorganization
     Agreement, the InterCAP stockholders will have agreed, jointly and
     severally, to indemnify Intergraph and Intergraph Sub and their respective
     affiliates, successors and assigns (the "Indemnified Persons") against
     certain losses arising from a breach of the representations and warranties
     made by InterCAP in the Reorganization Agreement.  However, the maximum
     liability of each InterCAP stockholder for such indemnification will not
     (in the absence of fraud, willful misrepresentation, willful omission of a
     material fact, or violations of the applicable securities laws) exceed such
     stockholder's pro rata share of the Escrow Shares.  See "The Merger and
     Related Transactions--Escrow Agreement."

          Termination of the Reorganization Agreement
         
          The Reorganization Agreement may be terminated under certain
     circumstances, including termination by the mutual consent of Intergraph,
     Intergraph Sub and InterCAP, termination by InterCAP in the event the
     InterCAP Board of Directors determines to pursue a superior offer
     concerning a merger or similar transactions, and termination by Intergraph,
     Intergraph Sub or InterCAP if the Merger is not consummated on or before
     January 15, 1995.  See "The Reorganization Agreement--Termination."

          Amendment of the Reorganization Agreement

          The Reorganization Agreement may be amended by the parties thereto as
     provided therein, provided such amendment is in writing, at any time before
     or after the approval and adoption of the Reorganization Agreement and the
     Merger by the InterCAP stockholders.  After any such stockholder approval
     and adoption has been obtained, however, no amendment of any of the
     agreements executed in connection with the Merger may be made that reduces
     the total Merger consideration or that materially affects the rights of
     InterCAP's stockholders hereunder, without obtaining such further approval.
     See "The Reorganization Agreement--Amendment."

          Expenses of the Merger; Termination Fee

          Each party to the Reorganization Agreement will pay its own costs and
     expenses incident to the Reorganization Agreement and in carrying out the
     transactions contemplated thereby.  Notwithstanding the foregoing, the
     Reorganization Agreement requires InterCAP to reimburse Intergraph for its
     transaction expenses (including attorneys fees) in connection with the
     Reorganization Agreement if InterCAP intentionally breaches the covenants
     in the Reorganization Agreement or makes certain knowing material
     misstatements to Intergraph in connection therewith.  In addition, the
     Reorganization Agreement requires InterCAP to pay a termination fee to
     Intergraph if InterCAP terminates the Reorganization Agreement to pursue a
     superior offer, if the InterCAP Board of Directors withdraws or modifies
     its recommendation to the stockholders concerning the Merger, or if the
     stockholders disapprove the Merger and then pursue a superior offer within
     180 days.  Such termination fee, if any, will be equal to the greatest of
     (i) Intergraph's expenses (not to exceed $300,000), (ii) $200,000 and (iii)
     10% of the excess of the total consideration received in the superior offer
     over $7,500,000.  See "The Reorganization Agreement--Termination Fee."


     The Charter Amendment

          The Board of Directors of InterCAP has adopted resolutions
     recommending, and at the Meeting InterCAP stockholders will be asked to
     consider and act upon, the Charter Amendment.  The Charter Amendment would
     extend the date (from October 1, 1994 to January 15, 1995) upon which the
     liquidation preference of the InterCAP Series A Preferred Stock would be
     increased from $1.475 per share to $1.475 per share plus one-half of all
     accrued but unpaid dividends thereon.  See "Stockholder Approval of
     Reorganization

     InterCAP's Certificate of Incorporation," and "Appendix B--Form of
     Amendment to InterCAP's Certificate of Incorporation."


     Vote of Stockholders of InterCAP

          Stockholder Vote

          The Reorganization Agreement and the transactions contemplated thereby
     must be approved by the stockholders of InterCAP.  An amendment to the
     certificate of incorporation of InterCAP, as amended (the "InterCAP
     Certificate") must be approved prior to the consummation of the Merger.
     Accordingly, both the Charter Amendment and the Reorganization Agreement
     must be adopted and approved by the stockholders of InterCAP.

          Stockholder Meeting
    
          A special meeting of the InterCAP stockholders will be held on
     January 11, 1995 at 8:00 a.m. at the offices of InterCAP, 116 Defense
     Highway, Suite 400, Annapolis, Maryland 21401, for purposes of (i)
     consideration of the approval and adoption of the Charter Amendment; and
     (ii) consideration of the adoption and approval of the Reorganization
     Agreement (the "Meeting").      

          Record Date and Shares Entitled to Vote

          The Board of Directors of InterCAP has fixed the close of business on
     December 1, 1994 as the record date (the "Record Date") for the
     determination of stockholders entitled to notice of and to vote at the
     Meeting.  Accordingly, only InterCAP stockholders as of the close of
     business on the Record Date will be entitled to vote at the Meeting.  At
     the close of business as of the Record Date, there were the following
     number of shares of capital stock of InterCAP outstanding and entitled to
     vote: (i) 2,911,478 shares of InterCAP Common Stock and (ii) 3,597,155
     shares of InterCAP Preferred Stock, of which (A) 927,326 shares are
     designated InterCAP Series A Preferred Stock; (B) 1,716,387 shares are
     designated as InterCAP Series B Preferred Stock; and (C) 953,442 shares are
     designated as InterCAP Series C Preferred Stock.  Each share of InterCAP
     Common Stock and InterCAP Preferred Stock, respectively, is entitled to one
     vote per share, except that the InterCAP Series A Preferred Stock is
     entitled to 1.3329 votes per share of InterCAP Series A Preferred Stock.

          Proxies; Quorum

          Shares of InterCAP Common Stock and InterCAP Preferred Stock
     represented at the Meeting by properly executed proxies will, unless such
     proxies previously have been revoked, be voted in accordance with the
     instructions indicated in such proxies.  If no instructions are so
     indicated, such shares will be voted by InterCAP in favor of the adoption
     and approval of the Charter Amendment and adoption and approval of the
     Reorganization Agreement and the transactions contemplated thereby.

          Any InterCAP stockholder giving a proxy in the form accompanying this
     Prospectus/Proxy Statement has the power to revoke the proxy before its
     use.  A proxy can be revoked (i) by an instrument of revocation delivered
     before the Meeting to the Secretary of InterCAP, (ii) by a duly executed
     proxy bearing a later date or time than the date or time of the proxy being
     revoked, or (iii) by voting in person at the Meeting.  Attendance at the
     Meeting will not by itself revoke a proxy.

          The presence either in person or by properly executed proxy of the
     holders of a majority of the outstanding shares of each class of InterCAP
     Stock entitled to vote on the Charter Amendment and the Reorganization
     Agreement is necessary to constitute a quorum at the Meeting.

          Vote Required for Charter Amendment

          Under the InterCAP Certificate and the Delaware General Corporation
     Law ("Delaware Act"), approval and adoption of the Charter Amendment
     requires the affirmative vote of the holders of (i) a majority of the
     outstanding shares of InterCAP Common Stock and InterCAP Preferred Stock,
     voting as a single class; (ii) a majority of the outstanding shares of
     InterCAP Series A Preferred Stock, voting separately; (iii) a majority of
     the outstanding shares of InterCAP Series A Preferred Stock and InterCAP
     Series B Preferred Stock, voting as a single class; and (iv) a majority of
     the outstanding InterCAP Series C Preferred Stock, voting separately.  The
     failure of a holder of record of InterCAP Stock to vote in person or by
     proxy at the Meeting will have the same effect as a vote against the
     Charter Amendment.  Substantially all the holders of the InterCAP Preferred
     Stock have agreed to vote all their InterCAP Stock in favor of the Charter
     Amendment, and such holders have sufficient voting power to satisfy each of
     clauses (i)-(iv) above.  See "Stockholder Approval of Reorganization
     Agreement, the Merger and the Charter Amendment--Vote Required for Charter
     Amendment."  Accordingly, the Charter Amendment will be

                                      -14-
<PAGE>
 
     approved and adopted by InterCAP's stockholders at the Meeting even if no
     other stockholder of InterCAP votes in favor of the Charter Amendment.

          Vote Required for Reorganization Agreement and Merger

          Under InterCAP's Certificate and the Delaware Act, approval and
     adoption of the Reorganization Agreement and Merger requires the
     affirmative vote of (i) at least 66.67% of the outstanding shares of
     InterCAP Common Stock and the InterCAP Preferred Stock, voting as a single
     class, and (ii) a majority of the outstanding shares of InterCAP Series A
     Preferred Stock and InterCAP Series B Preferred Stock, voting as a single
     class.  The failure of a holder of record of InterCAP Stock to vote in
     person or by proxy at the Meeting will have the same effect as a vote
     against the Reorganization Agreement.  Although none of the InterCAP
     stockholders is under any contractual obligation to vote his or its shares
     of InterCAP Stock in favor of the Merger, the directors of InterCAP have
     indicated that they presently intend to vote all shares of InterCAP Stock
     over which they exercise voting power in favor of the Merger.  See
     "Stockholder Approval of Reorganization Agreement, the Merger and the
     Charter Amendment--Beneficial Security Ownership of Management."
     Accordingly, if the directors vote in accordance with their indication, the
     requisite stockholder approval required under the Reorganization Agreement
     will be obtained.

          Beneficial Security Ownership of Management

          The directors and executive officers of InterCAP beneficially owned,
     or exercised voting control over, as of September 30, 1994, 1,145,070
     shares (representing 39.33% of the total outstanding shares) of InterCAP
     Common Stock, 927,326 shares (representing 100.00% of the total outstanding
     shares) of InterCAP Series A Preferred Stock, which in turn represents
     1,236,033 votes, 1,696,657 shares (representing 98.85% of the total
     outstanding shares) of InterCAP Series B Preferred Stock, and 953,442
     shares (representing 100.00% of the total outstanding shares) of InterCAP
     Series C Preferred Stock.  Insofar as the holders of InterCAP Common Stock
     and InterCAP Preferred Stock are required to vote as a single class, such
     directors and executive officers beneficially own or control 73.80% of the
     combined classes; insofar as the holders of InterCAP Series A Preferred
     Stock and InterCAP Series B Preferred Stock are required to vote as a
     single class, such directors and executive officers beneficially own or
     control 99.33% of the combined classes.

                                  RISK FACTORS


     In addition to the information contained elsewhere in this Prospectus/Proxy
Statement, the following risk factors should be considered carefully in
evaluating the merits and risks of acquiring shares of Intergraph Common Stock
in the Merger.


Volatility of Share Price
        
     Intergraph Common Stock is traded on NASDAQ, and is subject to fluctuations
in market price.  See "Market Price Data".  Factors such as quarterly variations
in operating results, the announcement of technological innovations, strategic
partnerships or new product offerings by Intergraph or its competitors, and the
entrance of new competitors into the interactive computer graphics industry each
may have a significant impact on the market price of Intergraph Common Stock.
In addition, Intergraph Common Stock may experience price and volume
fluctuations unrelated to operating performance.  From the beginning of the 1994
fiscal year to the date of this Prospectus/Proxy Statement, the market price of
Intergraph Common Stock, as reported by NASDAQ, has ranged from a low of $7.75
per share to a high of $11.25 per share.  On December 6, 1994, the closing sale
price of Intergraph Common Stock as reported by NASDAQ was $8.00 per share.
The current market price of Intergraph Common Stock is presently at or near the
low end of its historical price range and such market price has declined during
recent quarters.  There can be no assurance that the Intergraph Common Stock
price will not experience further declines in the future.  In accordance with
the Escrow Agreement, except with respect to deposits into escrow of 30 or fewer
Escrow Shares on behalf of an InterCAP stockholder, the Escrow Shares will not
be released from escrow to InterCAP stockholders before the 90th day after the
Effective Date, and thus will remain subject to the risk of price declines
affecting the Intergraph Common Stock during such 90-day period.  Moreover, any
Escrow Shares released to Intergraph in satisfaction of the InterCAP
stockholders' indemnification obligations will be valued based on the Share
Determination Market Price as determined prior to the Effective Date, and thus
will not reflect the increase (if any) in the price of Intergraph Common Stock,
which would result in claims for indemnification being satisfied with property
having a greater value than the amount of the claim.      

    
Certain Tax Risks      
    
     Although it is expected that the Merger will constitute a tax-free
reorganization for federal income tax purposes (so that no gain or loss will be
recognized by InterCAP stockholders solely by virtue of the exchange of InterCAP
Stock for Intergraph Common Stock), the opinions of counsel rendered in
connection with the Merger include an important limitation to the effect that
certain contemplated distributions by limited partnership stockholders of
InterCAP to their partners, if they occur, may increase the risk that the Merger
would fail to qualify as a tax-free      

                                      -16-

reorganization for federal income tax purposes.  See "The Merger and Related
Transactions--Certain Federal Income Tax Considerations."      


Losses; Declining Financial Resources

     Intergraph incurred net losses of $.39 per share in the third quarter of
1994 and net losses of $.43 per share in the third quarter of 1993.  Net losses
for the first nine months of 1994 were $1.15 per share as compared to net losses
of $.99 per share for the first nine months of 1993.  Intergraph lost $2.51 per
share in the full year 1993 (including a restructuring charge of $1.34 per
share) as compared to earnings of $.18 per share (including a restructuring
charge of $.06 per share) and $1.47 per share in 1992 and 1991, respectively.
Intergraph's losses in 1993 were the result of a decline in systems revenue, an
overall decline in gross margin, and certain restructuring expenses from changes
in product sales and manufacturing strategies designed to make Intergraph more
competitive.  These strategic changes led to actions that resulted in an $89.8
million pretax restructuring charge in 1993, comprised of $10.5 million for
direct work force reductions, $17.1 million for elimination of operations, $56.1
million for revaluation of assets resulting from new product strategy, and $6.1
million for restructure of its electronics business.  The losses during the
first three quarters of 1994 are the result of a continuation of Intergraph's
product transition and resulting weak system sales.  See "Risk Factors--
Technological Change; Product Transition."  As a result of these losses,
Intergraph's cash balances have declined by 27% between January 1, 1994 and
September 30, 1994 and its short-term debt has increased by $24.7 million, of
which $24.4 million was incurred in third quarter of 1994.  Although Intergraph
continues to believe that its restructuring efforts and product transition
initiatives will result in reduced expenses and enhanced competitiveness, there
can be no assurance that the actions taken by Intergraph to date will be
sufficient to produce net earnings in future periods, or to prevent further
deterioration of Intergraph's cash position.


Technological Change; Product Transition

     Over the past several years, the industry in which Intergraph competes has
been characterized by a rapid move to higher performance and lower-priced
product offerings, by intense price and performance competition (including
competition from companies possessing greater financial resources than
Intergraph), by significantly shorter product cycles due to rapid technological
change, and by development and support of software standards that result in less
specific hardware dependency by customers.  As a consequence, the operating
results of Intergraph and others in the industry have and will continue to
depend on the ability to rapidly and continuously develop and deliver new
hardware products and new software products that are competitively priced, offer
enhanced performance, and meet customers' requirements for standardization and
interoperability.  There can be no assurance that Intergraph's efforts to
restructure its operations and product offerings, when complete, will be
successful in strengthening system sales or that Intergraph will be successful
in the future in developing or enhancing its products.

                                      -17-

Provisions Potentially Affecting Change in Control of Intergraph

     Intergraph's Certificate of Incorporation and Restated Bylaws contain
certain provisions that could have the effect of making it more difficult for a
third party to acquire, or discouraging a third party from attempting to
acquire, control of Intergraph.  In addition, during 1993, Intergraph adopted a
stockholder rights plan and distributed a dividend of one common share purchase
right for each outstanding share of Intergraph Common Stock.  See "Description
of Intergraph Common Stock--Stockholder Rights Plan."  These provisions may
reduce the likelihood of an acquisition of Intergraph at a premium price by a
third party.


No Dividends

     Intergraph has never paid dividends on the Intergraph Common Stock and does
not expect to pay dividends in the foreseeable future.  Intergraph currently
intends to retain future earnings, if any, to finance the operation and growth
of its business.


                               MARKET PRICE DATA


     Since April 1981, the Intergraph Common Stock has traded in the National
Association of Securities Dealers Automated Quotation System  ("NASDAQ") under
the symbol INGR.  As of September 30, 1994, there were 44,644,003 shares of
common stock outstanding, held by 5,430 stockholders of record.  The following
table sets forth, for the periods indicated, the high and low sale prices of
Intergraph Common Stock as reported on the NASDAQ National Market System.

     On September 29, 1994, the last full trading day prior to the signing of
the Reorganization Agreement, the closing price of Intergraph Common Stock as
reported on NASDAQ was $9.00 per share.  On December 6, 1994, the most recent
practicable full trading day prior to the date of mailing this Prospectus/Proxy
Statement, the closing price of Intergraph Common Stock as reported on NASDAQ
was $8.00.      

     No established public trading market exists for InterCAP Stock.  InterCAP
has not issued any shares of InterCAP Stock since July 1, 1992, except in
connection with the exercise of employee stock options and the exercise of
warrants that were granted as an inducement for certain loan guarantees made in
connection with indebtedness of InterCAP.  The exercise prices of these options
and warrants ranged from $.10 per share to $.42 per share.

     Following the Merger, Intergraph Common Stock will continue to be traded on
NASDAQ under the symbol "INGR."

     Neither Intergraph or InterCAP has ever paid cash dividends on their
respective shares of capital stock, and Intergraph anticipates that for the
foreseeable future it will continue to retain any earnings for use in the
operation of its business.


                            SELECTED FINANCIAL DATA


Intergraph Corporation

     The following selected financial data of Intergraph for each of the five
years ended December 31, 1993 are derived from the consolidated financial
statements of Intergraph Corporation, which were audited by Ernst & Young LLP,
independent auditors.  The selected financial data as of and for the nine month
periods ended September 30, 1994 and 1993 are derived from the unaudited
consolidated financial statements of Intergraph Corporation.  The unaudited
consolidated financial statements include all adjustments, consisting of normal
recurring accruals, which Intergraph considers necessary for a fair presentation
of the consolidated financial position and results of operations for these
periods.  Operating results for the nine months ended September 30, 1994 are not
necessarily indicative of the results that may be expected for the entire year
ending December 31, 1994.  The following selected financial data of Intergraph
should be read in conjunction with Intergraph's consolidated financial
statements and notes thereto and "Management's Discussion and Analysis of

                      THE MERGER AND RELATED TRANSACTIONS


Background of the Merger

     Beginning in early 1993, the Board of Directors of InterCAP and its
     management reached a conclusion that, based on the nature of InterCAP's
     products and customer mix, InterCAP would be unable to increase
     significantly its revenue base beyond historical levels absent access to a
     larger and more efficient product distribution network.  Because InterCAP's
     relatively narrow product line did not justify, in the Board's view, a
     direct investment in InterCAP to fund expansion of InterCAP's sales
     capability, InterCAP began to explore possible strategic means by which it
     could grow beyond the niche markets it served.

    
     Two fundamental factors underlying InterCAP's decision in 1993 to explore a
     strategic transaction were the redemption provisions of the InterCAP
     Preferred Stock and the liquidation preference of the InterCAP Series A
     Preferred Stock. At that time InterCAP's redemption obligations required it
     to redeem the InterCAP Preferred Stock in three annual installments, and
     honoring such obligations would have resulted in cash redemption payments
     to the holders of InterCAP Preferred Stock of approximately $1,403,000 on
     January 2, 1995, approximately $1,498,000 on January 2, 1996 and
     approximately $1,593,000 on January 2, 1997 (collectively, the "Intercap
     Redemption Obligations"). Because of InterCAP's market position and
     financial performance, certain holders of InterCAP Preferred Stock
     indicated in 1993 that they would be unwilling to waive their redemption
     rights and would seek liquidity through redemption unless InterCAP could
     provide liquidity through some other mechanism or could consummate a
     strategic transaction that provided InterCAP with an opportunity to
     increase significantly its revenues. Although the holders of InterCAP
     Preferred Stock had previously agreed to limit InterCAP's annual redemption
     obligations to its net income during the preceding 12 months, InterCAP's
     management concluded that redemption of the InterCAP Preferred Stock would
     restrict severely its ability to attract additional capital and hinder its
     ability to invest in its long-term growth.      

     In addition to the redemption provisions of the InterCAP Preferred Stock,
     management of InterCAP believed that the liquidation preference of the
     InterCAP Series A Preferred Stock would be an impediment to attracting
     additional capital or consummating a strategic transaction with, or an
     acquisition of InterCAP by, a third party.  In early 1993, InterCAP was
     expecting to post a loss for its fiscal year ended June 30, 1993 and did
     eventually post a loss of approximately $515,000.  In light of this
     expected financial performance and its effect on the value of InterCAP as a
     whole, management believed that if InterCAP were sold or participated in a
     strategic combination with one or more other companies, all or
     substantially all the proceeds from such a transaction would be distributed
     to the holders of InterCAP Preferred Stock in satisfaction of their
     liquidation preferences and, absent adjustment to such liquidation
     preferences, the amount of proceeds available for distribution to holders
     of InterCAP Common Stock, including employees who held options to acquire
     shares of InterCAP Common Stock, would be nominal at best.  In recognition
     of the importance of incentivizing InterCAP's employees to continue to
     build its business and to identify, negotiate and consummate a strategic
     transaction, in May 1993, the 

                                      -23-
 
<PAGE>
 
     Board of Directors of InterCAP proposed, and thereafter InterCAP's
     stockholders (including all holders of InterCAP Series A Preferred Stock)
     approved, an amendment to the InterCAP Certificate that reduced the
     liquidation preference of the InterCAP Series A Preferred Stock from $1.475
     per share plus all accrued but unpaid dividends thereon to $1.475 per share
     plus (if the effective date of the liquidation was after October 1, 1994)
     an amount equal to one-half of all accrued but unpaid dividends thereon.
     The primary purpose of this amendment was to create the potential to shift
     some of the implied value of the InterCAP Series A Preferred Stock to the
     InterCAP Common Stock and thereby provide incentives to InterCAP's
     management to increase the value of InterCAP and consummate a strategic
     transaction or sale of InterCAP by October 1, 1994.

     From late 1993 through the first quarter of 1994, InterCAP gave serious
     consideration to participation in a three-way merger with two companies of
     a similar size to InterCAP and with complementary businesses.  Parallel to
     this effort, discussions were held on how to fund the combined entity.  It
     became apparent that the financing requirements of the combined entity
     would be significant, and that InterCAP's capital structure would be an
     impediment to obtaining the necessary financing from traditional venture
     capital sources because of the general unwillingness or inability of the
     holders of InterCAP Preferred Stock to participate in such financing or to
     subordinate their positions to a new investor.  After it became apparent
     that a combination of equals could not be financed with traditional venture
     capital financing, InterCAP's management conducted informal discussions
     with a number of potential corporate partners, including Intergraph.  These
     discussions, however, were not successful.  InterCAP's management also
     contacted several investment banking firms to determine whether a combined
     entity could be financed through an initial public offering ("IPO").  While
     some interest was expressed, the financing requirements were viewed as too
     small for large investment banking firms and too large for small investment
     banking firms.  With no other financing alternatives, the three-way merger
     transaction was abandoned.

     After abandoning the three-way merger and with the liquidation preference
     of the InterCAP Series A Preferred Stock scheduled to increase on
     October 1, 1994, InterCAP's management, under the direction of its Board of
     Directors, began to explore a sale of the company. InterCAP first
     considered an IPO as a stand-alone company, but potential underwriters
     indicated that because of InterCAP's size and capital structure, an IPO
     would not be feasible in the short term, would not be of a size that would
     result in the automatic conversion of the InterCAP Preferred Stock into
     InterCAP Common Stock, and could not be expected to provide a reasonable
     return for InterCAP's stockholders. After careful consideration, the Board
     of Directors concluded that an IPO entailed greater risks and a lower
     probability of success than a sale of InterCAP as a means of achieving
     liquidity for InterCAP's stockholders.

     InterCAP's management believed that a few companies, including Intergraph,
     were the most logical acquisition candidates for InterCAP and approached
     these companies early in the second quarter of 1994 regarding their
     interest in a possible acquisition of InterCAP.  InterCAP also sought to
     engage an investment firm to assist it in identifying potential acquirors
     of InterCAP with whom InterCAP did not have a prior relationship.  The
     first two investment banking firms 

                                      -24-

<PAGE>
 
both declined to accept an engagement with InterCAP and in connection with such
declination indicated that it would be difficult to find a company interested in
acquiring InterCAP and that if one were found, the expected value of the 
transaction to InterCAP's stockholders would be in the range of one times its 
revenues for the preceding 12 month period.  InterCAP ultimately retained an 
investment banker in May 1994 and while a number of potential acquirors were 
contacted as a result of this engagement and some interest was expressed, no 
company contacted made an offer to acquire InterCAP or any proposal involving a 
transaction with InterCAP, and no company was willing to move forward to 
negotiate a transaction on a timely basis.

     InterCAP first approached Intergraph about a possible acquisition on April 
20, 1994.  On that date, management of InterCAP telecopied a memorandum to 
Intergraph, advising that a decision had been made by the Board of Directors of 
InterCAP to explore selling the company and soliciting an indication of interest
on the part of Intergraph in possibly acquiring InterCAP.  A representative of 
Intergraph telephoned the President of InterCAP later that day to express a 
positive interest and to suggest that a meeting be held to discuss such a
transaction. At the first such meeting, held on June 17, 1994, the parties
discussed the general terms upon which they might both agree to an acquisition
of InterCAP, including that the acquisition price would generally be in the
range of approximately 1.5 times InterCAP's annual revenues.

     During the next several weeks, through the months of July and into early
August, 1994, management of Intergraph and InterCAP spoke on a limited basis by
telephone and through correspondence about the other requirements each party
would have in a transaction and the possible benefits to each party of such a
transaction. On August 16, 1994, operational officers of InterCAP and Intergraph
met to discuss each party's products and technology, focusing on whether
InterCAP's technology would be of benefit to Intergraph and its product
offerings and on whether Intergraph could provide a wider distribution network
for InterCAP's existing products. Following this meeting, each of the parties
considered the potential benefits to them and decided to continue discussions on
the specific terms and conditions of a transaction.

     On August 23, 1994, the Presidents of InterCAP and Intergraph met to
outline the parameters for a transaction and reached a preliminary understanding
concerning the price and structure of a proposed acquisition. They agreed that
their understanding was subject to the negotiation of acceptable documentation,
approval by their respective boards of directors, the completion by Intergraph
of a comprehensive due diligence review of InterCAP, and other matters. Because
the liquidation preference of the InterCAP Series A Preferred Stock was
scheduled to increase beginning on October 1, 1994, InterCAP indicated to
Intergraph a strong desire to conclude negotiations and execute a binding
agreement by the end of September, 1994 and to reach a separate agreement with
the holders of the InterCAP Series A Preferred Stock to postpone the
effectiveness of the increase in the liquidation preference to the earliest
future date by which consummation of the Merger could be assured.

     Commencing during the last week of August of 1994 and throughout the month
of September of 1994, Intergraph performed a due diligence review of the
legal, financial and technical aspects of InterCAP's business.  Intergraph
also directed its counsel to begin preparation 

                                      -25-
<PAGE>
 
of a draft of the Reorganization Agreement, and on September 8, 1994, the
initial draft of the Reorganization Agreement was distributed by Intergraph's
counsel to representatives of InterCAP and InterCAP's counsel. Thereafter,
further due diligence and negotiations concerning the Reorganization Agreement
(as well as the additional agreements contemplated thereby) proceeded
simultaneously. Throughout this time period, members of the boards of directors
of InterCAP and Intergraph were kept apprised of the status of discussions. The
InterCAP Board of Directors met on September 12, 1994 to discuss the progress of
negotiations, and met again on September 26, 1994 to approve the Reorganization
Agreement in the form of the draft furnished to the directors on September 24,
1994, with such changes as the executive officers of InterCAP might approve.
Negotiations continued until September 30, 1994 when the Reorganization
Agreement, the Preferred Stock Agreement, and various employment agreements
contemplated thereby were executed.
 
    
     Promptly following the execution of the Reorganization Agreement on 
September 30, 1994, representatives of InterCAP and Intergraph commenced 
preparation of this Prospectus/Proxy Statement and the related Registration 
Statement, which Registration Statement was ultimately filed on October 28, 
1994. Thereafter, InterCAP and Intergraph determined that the Registration 
Statement had not been declared effective early enough to permit consummation of
the Merger by December 31, 1994--the date specified in the Reorganization 
Agreement as the time at which either Intergraph or InterCAP would be permitted 
to unilaterally terminate the Reorganization Agreement if the Merger had not yet
been consummated (the "Merger Termination Date"). Both Intergraph and InterCAP 
desired to extend the Merger Termination Date to allow consummation of the 
Merger after December 31, 1994. In order to do so, however, Intergraph and 
InterCAP determined that it first would be necessary to postpone the effective 
date of the InterCAP Redemption Obligations for substantially all the InterCAP 
Preferred Stock (which otherwise would have become operative beginning on 
January 2, 1995) in order to allow additional time for the Merger to be 
consummated. Accordingly, in early December of 1994, InterCAP sought and 
obtained a written commitment from the Specified Preferred Stockholders (as 
hereinafter defined) to postpone the effective date of the InterCAP Redemption 
Obligations relating to substantially all the InterCAP Preferred Stock from 
January 2, 1995 until January 16, 1995. In reliance upon that written 
commitment, InterCAP, Intergraph Subsidiary and Intergraph then executed 
Amendment No. 1 to Agreement and Plan of Reorganization dated as of December 7, 
1994 (the "Reorganization Agreement Amendment"), which extended the date by 
which the conditions of Closing contained in the Reorganization Agreement were 
required to be satisfied (or waived) from December 31, 1994 until January 15, 
1995.      
 
Joint Reasons for the Merger
 
     Intergraph and InterCAP have identified various potential mutual benefits
of the Merger that they believe will contribute to the achievement by Intergraph
and InterCAP of their strategic goals and objectives, including the following:

     .    increased technical, marketing and distribution resources to enable
          the InterCAP products to compete more effectively in the market for
          technical illustration software;

     .    the availability of greater research and development resources to be
          applied to the development and enhancement of InterCAP's products;

     .    the synergistic benefits available from combining InterCAP's
          technology and presence in key markets with Intergraph's complementary
          array of products and market position;

     .    the enhancement of the information delivery component of Intergraph's
          software products by the addition of InterCAP's technical know-how and
          expertise in that area; and

     .    the ability of Intergraph and InterCAP to collaborate on future
          product development.


Intergraph's Reasons for the Merger

     In addition to the anticipated mutual benefits described above, the Board
of Directors of Intergraph believes that the Merger may enhance Intergraph's
ability to compete in the market 

                                      -26-
<PAGE>
 
for various software products, including those used to create and maintain
technical illustrations. Intergraph believes that the Merger reasonably may be
expected to:

     .    improve Intergraph's market position in publishing and document
          management  software markets by enhancing credibility with customers,
          business alliances and standards organization;

     .    demonstrate to customers and others Intergraph's serious intention to
          enhance its product mix for publishing, document management and
          technical illustration markets;

     .    enhance Intergraph's marketplace credibility and acceptance in the
          market for Interactive Electronic Technical Manual ("IETM") software
          products more quickly than could be accomplished without the Merger;

     .    afford Intergraph with access to InterCAP's installed customer base of
          over 150 customers (having an especially strong concentration of
          aerospace, automotive, manufacturing and electronics customers), many
          of which are not present customers of Intergraph;

     .    provide Intergraph with additional technical expertise in the use of
          Computer Graphics Metafile ("CGM") as well as other graphic formats,
          the design and development of IETM's, the integration of technical
          illustration products, and the development of standards-based
          publishing products;

     .    permit Intergraph to influence the development of international
          standards relating to IETM's and CGM technology; and

     .    improve Intergraph's position in the desktop technical illustration
          market and support Intergraph's effort to achieve a leading position
          in publishing and document management software markets.
    
     In the course of its deliberations concerning the Merger, Intergraph's
Board of Directors received presentations from, and reviewed a number of
additional relevant factors with, Intergraph's management.  The principal
factors considered by Intergraph's Board of Directors in determining the
exchange ratio for the Merger were InterCAP's historical and projected revenue,
the strategic benefits of the acquisition as described above, and the
complementary nature of InterCAP's product mix and customer base with the
product mix and customer base of Intergraph.  The Intergraph Board of Directors
also considered the transaction prices for certain other acquisitions in the
engineering, publishing and graphic arts software markets as a multiple of the
acquired firms' annual revenues.  Applying these factors to InterCAP, Intergraph
arrived at an aggregate purchase price for the entire equity interest in
InterCAP of $7.5 million.  The exchange ratio for the InterCAP Series A
Preferred Stock was established at $1.475 based on the liquidation preference
provisions of the InterCAP Certificate, as in effect on September 30, 1994 when 
the      

                                      -27-
<PAGE>

     
Reorganization Agreement was originally executed (which provisions are
applicable in the case of a transaction such as the Merger). The exchange ratio
for the remaining InterCAP Stock of $0.90975693 per share was then determined
from the aggregate $7.5 million amount (but after reduction to reflect the value
of the Assumed Options and reduction to reflect the $1.475 liquidation
preference required to be paid in respect of the InterCAP Series A Preferred
Stock).      


InterCAP's Reasons For The Merger

     In addition to the anticipated mutual benefits described above, the
InterCAP Board of Directors believes that the Merger provides InterCAP and its
stockholders with liquidity, an attractive return on their investments and a
number of other strategic benefits that would not be available if InterCAP were
to remain as a stand-alone company.
    
     InterCAP's Board of Directors believes that the shares of Intergraph Common
Stock to be received by the stockholders of InterCAP will enable them to realize
an attractive return on their investment compared to available alternatives.
The holders of InterCAP Series A Preferred Stock will receive shares of
Intergraph Common Stock with a value of $1.475 per share, which is equal to the
original price paid to InterCAP for such stock in December 1988.  This price is
believed to be attractive to the holders of the InterCAP Series A Preferred
Stock because it represents a significant increase in the perceived value of the
InterCAP Series A Preferred Stock since 1990, when InterCAP was in serious
financial trouble.  The holders of InterCAP Series B Preferred Stock and
InterCAP Series C Preferred Stock will receive shares of Intergraph Common Stock
with a value of approximately $.91 per share, which is in excess of the current
liquidation preferences for both of those series of InterCAP Preferred Stock and
approximately $.41 per share and $.25 per share, respectively, in excess of the
original issue price for such stock.  Similarly, the holders of InterCAP Common
Stock will receive shares of Intergraph Common Stock with an initial value that
is in all cases in excess of the original issue price paid to InterCAP for such
shares.  Although the InterCAP directors recognize that no assurance can be
given that the value of the Intergraph Common Stock will remain at the Share
Determination Market Price used in the Merger, they collectively believe that
the aggregate consideration to be received by InterCAP stockholders in the
Merger is fairly representative of the value of InterCAP as of the date of the
Reorganization Agreement.  This belief, although subjective, is based on the
Board's intimate familiarity with InterCAP's history and financial and strategic
position at the time the Reorganization Agreement was negotiated, as discussed
above under "Background of the Merger," and on all the other factors considered
by InterCAP's Board of Directors in assessing the proposed Merger, both positive
and negative, as discussed below.  The InterCAP Board of Directors did not,
however, seek or obtain the opinion of any investment banking firm with respect
to the fairness of the Merger, from a financial point of view, to the InterCAP
stockholders because of cost and timing concerns, the collective experience of
the Board with respect to similar private company transactions, and a
recognition by the Board that the consideration to be received from Intergraph
was at a price that was in excess of the price that the Board expected would be
received upon a sale of InterCAP.  Instead of relying on a fairness opinion from
an investment banking firm, the Board gave detailed attention to the financial
aspects of the Merger      

                                      -28-
<PAGE>
 
and considered carefully the views of its management members, outside directors
and venture capital firm representatives, all of whom have significant prior
business and software industry experience and financial acumen, as to the proper
valuation of InterCAP. Although InterCAP's Board of Directors, taken as a whole,
possesses sufficient voting control over shares of InterCAP Stock to approve the
Merger without action by any other InterCAP stockholder, a majority of the Board
members are not employed by InterCAP, and their financial interests in InterCAP
and the Merger are limited to being holders of InterCAP Stock and receiving the
consideration therefor contemplated by the Merger Agreement.

     At a meeting of the InterCAP Board of Directors held on November 28, 1994,
the Board, after reviewing InterCAP's financial position and results of
operations since September 26, 1994 and other factors it deemed relevant
regarding InterCAP and Intergraph since that date, unanimously reaffirmed its
initial conclusion that the aggregate consideration to be received by
InterCAP stockholders in the Merger is fairly representative of the value of
InterCAP as of such date.

     The InterCAP Board of Directors viewed the Merger as a means by which
InterCAP stockholders would be able to obtain liquidity for their InterCAP
Stock.  Providing liquidity to InterCAP's stockholders was of critical
importance to InterCAP's Board of Directors for a number of reasons.  First,
many holders of InterCAP Common Stock originally invested in InterCAP in 1987,
and it was perceived that providing a route to liquidity to these stockholders
was long overdue.  Second, the redemption provisions of the InterCAP Preferred
Stock and the pending adjustment to the liquidation preference of the InterCAP
Series A Preferred Stock forced InterCAP ultimately to identify and pursue a
transaction that would provide liquidity to the holders of InterCAP Preferred
Stock.  Finally, the Merger provides InterCAP's stockholders with the only route
to liquidity that is reasonably available to InterCAP today.  In this regard-
the Board of Directors considered the feasibility and prospects of alternative
means to provide liquidity for InterCAP stockholders, including other potential
business combinations and an IPO.  The Board of Directors also considered
whether any other potential acquiror might offer the same or similar benefits to
InterCAP, and concluded that no other company had the strategic fit or could
offer the benefits available from Intergraph within the same time frame.  See
"The Merger and Related Transactions--Background of the Merger."

     In evaluating the proposed Merger, the InterCAP Board of Directors
discussed and considered a wide variety of factors, including the relative value
of InterCAP as reflected in the proposed Reorganization Agreement compared with
the implied valuation of InterCAP based on comparable publicly traded companies
(including Autodesk, Inc., Auto-trol Technology Corporation, Frame Technologies
and Interleaf), as well as the potential dilution/accretion to InterCAP
stockholders that would result from the transaction.  The Board of Directors
reviewed the history of merger discussions with Intergraph, as well as the
status of discussions with other potential corporate strategic partners,
investors and acquirors.  The Board of Directors also considered the advantages
and disadvantages that the Merger would present to InterCAP's achievement of its
strategic objectives.  As part of the evaluation process, the Board of Directors
reviewed extensive information about the business, operations and future
prospects of both 

                                      -29-
<PAGE>
 
InterCAP and Intergraph, including annual, quarterly and other reports and proxy
statements filed by Intergraph, and InterCAP's current business plan and
projected financial results of operations. In addition, the Board analyzed and
reviewed the proposed Reorganization Agreement.

     After completing its evaluation, the Board of Directors concluded that the
proposed Merger would afford InterCAP many advantages and a greater opportunity
to accomplish its strategic objectives, including the following:

     .    direct access to Intergraph's distribution channels to distribute
          InterCAP's existing software products to Intergraph's large and
          diversified customer base;

     .    access to necessary product distribution channels not presently
          available to InterCAP through which it may market and sell its new
          products, including native CGM architecture products and products
          based on Microsoft or Intel (as opposed to UNIX) operating systems;

     .    access to significant research and development resources to help
          diversify InterCAP's traditional products and services; and

     .    minimal, if any, disruption to InterCAP's employees and existing
          customers.

     The Board also evaluated the effect of the proposed merger on InterCAP's
stockholders and concluded that the proposed Merger offered many advantages to
them as well, including the following:

     .    converting an illiquid investment into a liquid investment;

     .    providing InterCAP's investors with a positive return on their
          InterCAP investment that likely exceeds the return achievable from the
          various alternatives considered by the Board of Directors;

     .    providing InterCAP's stockholders with an opportunity to be investors
          in a combined graphics company with greater resources and potential
          than InterCAP as a stand-alone company; and
    
     .    providing a tax-free exchange of InterCAP Stock for Intergraph Common
          Stock, although the Board was aware that counsel's opinion on this
          issue would recognize that the issue was not free from doubt and
          subject to some legal uncertainty.     

     After considering the foregoing factors, the Board of Directors unanimously
approved the Reorganization Agreement and the transactions contemplated thereby,
including the Merger, and recommended that the stockholders of InterCAP approve
and adopt the Reorganization Agreement and the Merger.  In view of the wide
variety of factors considered, both positive and negative, 

                                      -30-
<PAGE>
 
InterCAP's Board of Directors did not find it practicable to, and did not,
quantify or otherwise assign relative weights to the specific factors
considered.


InterCAP Board Recommendation

     THE BOARD OF DIRECTORS OF INTERCAP BELIEVES THAT THE MERGER IS FAIR TO AND
IN THE BEST INTERESTS OF INTERCAP AND ITS STOCKHOLDERS AND THEREFORE UNANIMOUSLY
RECOMMENDS THAT STOCKHOLDERS VOTE FOR THE APPROVAL AND ADOPTION OF THE
REORGANIZATION AGREEMENT AND THE MERGER.


Effect on InterCAP if Merger is not Approved

     As a part of the negotiation of the Reorganization Agreement, Intergraph
did not require the directors of InterCAP or any other InterCAP stockholder to
agree to vote their shares of InterCAP Stock in favor of the Merger.
Intergraph's position was based on its recognition that a competing offer to
acquire InterCAP could create a fiduciary conflict for directors of InterCAP,
and that any voting agreement with such persons likely would contain significant
exceptions or, if not, might be vulnerable to legal challenge.  In lieu of
voting agreements from InterCAP's major stockholders, Intergraph instead
negotiated a termination fee to protect itself in the event of a competing offer
to acquire InterCAP.  See "The Reorganization Agreement--Termination Fee."
Accordingly, neither InterCAP's directors nor any InterCAP stockholder is
contractually obligated to vote in favor of the Merger.  See "Stockholder
Approval of Reorganization Agreement, the Merger and the Charter Amendment."
    
     Because each of the directors of InterCAP has indicated that he currently
intends to vote all shares of InterCAP Stock over which he has voting control in
favor of the Merger, and because such votes would be sufficient to approve the
Merger, InterCAP believes that, absent extraordinary circumstances (such as the
submission by a third party of a superior offer for InterCAP), the requisite
stockholder approval for the Merger will be obtained.  This indication from
InterCAP's directors, however, is not equivalent to an enforceable contractual
obligation, and each director remains free to vote against, or not vote at all
with respect to, the Merger.  InterCAP believes that the most likely event that
would cause one or more of its directors to vote against the Merger would be the
submission by a third party of a superior competing offer to acquire InterCAP.
Although InterCAP believes the probability of such an event occurring to be low,
if it were to happen, InterCAP's Board would be permitted to consider such offer
under the terms of the Reorganization Agreement, and based on such
consideration, could modify its recommendation to InterCAP's stockholders with
respect to approval of the Merger.  If the Merger were not approved because of
the modification or withdrawal of the InterCAP Board's recommendation in the
face of a higher competing offer to the Merger, InterCAP expects that it would
move rapidly to close such a competing transaction.     

                                      -31-
<PAGE>
 
    
     In addition, even if the requisite stockholder approval for the Merger is
obtained, it is possible that the Merger might not be consummated based on the
failure of InterCAP to satisfy one or more of the conditions to consummation of
the Merger.  See "The Reorganization Agreement--Conditions to the Merger."
Among other things, such a failure to satisfy closing conditions could occur if
InterCAP and Intergraph did not receive Continuity Certificates covering at
least 50% of the shares of Intergraph Common Stock in the Merger, or if holders
of more than 5% of the InterCAP Stock preserved their dissenter's rights with
respect to the Merger.     
    
     If the Merger is not approved or consummated for other reasons, InterCAP
will be faced with commencement on January 16, 1995 of a mandatory redemption of
a portion of the InterCAP Preferred Stock held by the Specified Preferred
Stockholders, and it is unlikely that InterCAP would have the requisite cash
resources to meet those obligations without serious disruption of its
operations. In addition, effective January 15, 1995, the liquidation preference
for the InterCAP Series A Preferred Stock will increase by an aggregate of
approximately $450,000, which would reduce the amount other holders of InterCAP
Stock would receive in a transaction like the Merger by a similar amount.
Although certain holders of InterCAP Preferred Stock have expressed an
unwillingness to further postpone or modify the redemption provisions for a
significant period of time, InterCAP would attempt to negotiate a further
deferral of the InterCap Redemption Obligations beyond January 16, 1995 in order
to provide it with additional time to identify a potential alternate acquisition
candidate. If such negotiations proved unsuccessful or if an alternative
transaction could not be consummated, InterCAP could be forced to pursue more
drastic means to prevent redemption of the InterCAP Preferred Stock, including
filing for bankruptcy protection under Chapter 11 of the United States
Bankruptcy Code. If the Merger is not consummated, no assurance can be given
that InterCAP would be successful in negotiating an extension of its redemption
obligations or in consummating a transaction to replace the proposed Merger.
    

Interests of Certain Persons in the Merger

     In assessing the terms and conditions of the proposed Reorganization
Agreement and the Merger, the Board of Directors of InterCAP was aware that the
Reorganization Agreement and the Merger would have various consequences in which
certain executive officers and directors of InterCAP would have an interest.  In
considering the recommendations of InterCAP's Board of Directors with respect to
the Merger, InterCAP stockholders should be aware that certain executive
officers and directors of InterCAP have interests in the Merger discussed below
that are in addition to the interests of InterCAP stockholders generally.
    
     Certain Interests of A.G.W. Biddle III     

     In accordance with the terms of the existing employment agreement dated
September 10, 1990 by and between InterCAP and A.G.W. Biddle, III ("Biddle"),
the President and Chief Executive Officer and a director of InterCAP, the Merger
will constitute a "change in control" of InterCAP as defined in such agreement.
Under that agreement, a change in control will result in a payment to Biddle
following the Merger of $167,000.  In addition, Biddle may elect to continue
certain employee benefits under InterCAP policies and practices for a period of
one year 

                                      -32-
<PAGE>
 
following the change in control. These aspects of Biddle's 1990 employment
agreement, among other matters, are confirmed in a new employment agreement
between Biddle and Intergraph Sub, the effectiveness of which is conditioned
upon consummation of the Merger (the "Biddle-Intergraph Employment Agreement").
The Biddle-Intergraph Employment Agreement would become effective only upon
consummation of the Merger and would continue, unless otherwise terminated in
accordance with the terms of such agreement, for a period of three months from
the Effective Date.

     Under the Biddle-Intergraph Employment Agreement, Biddle's salary and bonus
would continue at their pre-Merger levels, and accordingly, Mr. Biddle's total
salary and bonus for the three month term of his employment by the Surviving
Corporation will be $41,750.  The Biddle-Intergraph Employment Agreement also
obligates Biddle to a non-competition agreement for a period of two years
following termination of his employment (unless such termination is occasioned
(i) by InterCAP's breach of the agreement, or (ii) because InterCAP terminates
Biddle's employment without cause, in which case Biddle would only be obligated
under the noncompetition provisions if InterCAP paid him a lump sum of $167,000
within thirty days of termination). Under the terms of the Biddle-Intergraph
Employment Agreement, a loan in the principal amount of $30,000 previously made
by InterCAP to enable Biddle to exercise stock options on September 13, 1993 (i)
will not be forgiven and will be required to be repaid within thirty months
following the Effective Date, and (ii) will continue to bear interest upon its
original terms, with such interest to be forgiven by InterCAP at the end of each
year until the note matures.

     Upon consummation of the Merger, by virtue of resolutions adopted by the
InterCAP Board of Directors on September 26, 1994, Biddle will receive NQSO's
under the InterCAP Option Program to acquire 80,724 additional shares of
InterCAP Common Stock at an exercise price of $.10 per share.  Accordingly, the
aggregate difference as of the Effective Date, between the applicable exchange
ratio in the Merger and the exercise price for these options will be $65,366.82.
These options will be fully vested upon issuance and will be exercisable up to
five years following the Effective Date in accordance with Biddle's 1990
employment agreement with InterCAP.

     In addition to the NQSO's described in the immediately preceding paragraph,
Biddle is the beneficial owner of 508,586 shares of InterCAP Common Stock,
11,986 shares of InterCAP Series A Preferred Stock, and 19,027 shares of
InterCAP Series B Preferred Stock.  See "Security Ownership of Certain
Beneficial Owners and Management of InterCAP."

     Certain Interests of John C. Gebhardt

     In connection with the Merger, Intergraph has required that John C.
Gebhardt ("Gebhardt"), a director and officer of InterCAP, enter into an
employment agreement (the "Gebhardt Employment Agreement") with Intergraph Sub
which will become binding upon InterCAP as the Surviving Corporation in the
Merger.  Gebhardt currently has no employment agreement with InterCAP.  The
Gebhardt Employment Agreement would become effective only 

                                      -33-
<PAGE>
 
upon consummation of the Merger and would continue, unless otherwise terminated
in accordance with the terms of such agreement, for a period of two years from
the Effective Date. Under the Gebhardt Employment Agreement, Gebhardt's salary
would continue at its pre-Merger level and Gebhardt would be paid additional
incentive compensation similar to his current incentive compensation at a rate
of $10,000 per year ($833 per month) until InterCAP adopts an incentive
compensation program that affords Gebhardt a reasonable opportunity to earn
annual cash awards of not less than $10,000. The Gebhardt Employment Agreement
also obligates Gebhardt to a non-competition agreement for a period of two years
following termination of his employment. In the event the Gebhardt Employment
Agreement is terminated by InterCAP without cause, or is breached by InterCAP,
Gebhardt is entitled to receive, as a lump sum, the greater of his compensation
for the remaining term of the agreement or one-half of his gross annual salary.
Under certain other circumstances, Gebhardt may receive termination pay of one-
half his gross annual salary. Under the terms of the Gebhardt Employment
Agreement, a loan in the principal amount of $35,640 previously made by InterCAP
to enable Gebhardt to exercise stock options on September 13, 1993 (i) will be
forgiven by InterCAP if Gebhardt remains an InterCAP Employee until the second
anniversary of the Effective Date, and (ii) will continue to bear interest upon
its original terms, with such interest to be forgiven by InterCAP at the end of
each year until the note matures.

     Upon consummation of the Merger, by virtue of resolutions adopted by the
InterCAP Board of Directors on September 26, 1994, Gebhardt will receive NQSO's
under the InterCAP Option Program to acquire 95,920 additional shares of
InterCAP Common Stock at an exercise price of $.10 per share.  Accordingly, the
aggregate difference, as of the Effective Date, between the applicable exchange
ratio in the Merger and the exercise price for these options will be $77,671.89.
These options will be 50% vested when granted with an additional 25% to vest on
each of the first and second anniversaries of the Effective Date.

     In addition to the NQSO's described in the immediately preceding paragraph,
Gebhardt is the beneficial owner of 484,205 shares of InterCAP Common Stock.
See "Security Ownership of Certain Beneficial Owners and Management of
InterCAP."

     Certain Interests of Thomas O. Mills

     In connection with the Merger, Intergraph has required that Thomas O. Mills
("Mills"), a director and officer of InterCAP, enter into an employment
agreement (the "Mills Employment Agreement") with Intergraph Sub which will
become binding upon InterCAP as the Surviving Corporation in the Merger.  Mills
currently has no employment agreement with InterCAP.  The Mills Employment
Agreement would become effective only upon consummation of the Merger and would
continue, unless otherwise terminated in accordance with the terms of such
agreement, for a period of two years from the Effective Date.  Under the Mills
Employment Agreement, Mills' salary would continue at its pre-Merger level and
Mills would be paid additional incentive compensation similar to his current
incentive compensation at a rate of $6,699 per year ($558 per month) until
InterCAP adopts an incentive compensation program that affords Mills a
reasonable opportunity to earn annual cash awards of not less than $10,000.  The
Mills Employment 

                                      -34-
<PAGE>
 
Agreement also obligates Mills to a non-competition agreement for a period of
two years following termination of his employment. In the event the Mills
Employment Agreement is terminated by InterCAP without cause, or is breached by
InterCAP, Mills is entitled to receive, as a lump sum, the greater of his
compensation for the remaining term of the agreement or one-half of his gross
annual salary. Under certain other circumstances, Mills may receive termination
pay of one-half his gross annual salary. Under the terms of the Mills Employment
Agreement, a loan in the principal amount of $14,872.50 previously made by
InterCAP to enable Mills to exercise stock options on September 13, 1993 (i)
will be forgiven by InterCAP if Mills remains an InterCAP Employee until the
second anniversary of the Effective Date, and (ii) will continue to bear
interest upon its original terms, with such interest to be forgiven by InterCAP
at the end of each year until the note matures.

     Upon consummation of the Merger, by virtue of resolutions adopted by the
InterCAP Board of Directors on September 26, 1994, Mills will receive NQSO's
under the InterCAP Option Program to acquire 43,450 additional shares of
InterCAP Common Stock at an exercise price of $.13 per share.  Accordingly, the
aggregate difference, as of the Effective Date, between the applicable exchange
ratio in the Merger and the exercise price for these options will be $33,880.04.
These options will be 50% vested when granted with an additional 25% to vest on
each of the first and second anniversaries of the Effective Date.

     Under the terms of certain option agreements issued by InterCAP under the
InterCAP Option Plan and denominated as incentive stock options, all such
options which are not vested will become immediately vested in full upon a
transaction such as the Merger.  As a result of the acceleration of vesting of
such options and upon consummation of the Merger, Mr. Mills will become entitled
to exercise ISO's to acquire up to an additional 17,000 presently unvested
shares of InterCAP Common Stock at an exercise price of $.42 per share, which
ISO's will be assumed by Intergraph pursuant to the Reorganization Agreement and
converted into options to purchase shares of Intergraph Common Stock.  The
aggregate difference between the applicable exchange ratio in the Merger and the
exercise price of these options, as of the Effective Date, will be $8,325.87.
See "The Merger and Related Transactions--Options Outstanding Prior to the
Merger."

     In addition to the NQSO's described above and the accelerated vesting of
options described in the immediately preceding paragraph, Mills is the
beneficial owner of 198,340 shares of InterCAP Common Stock.  See "Security
Ownership of Certain Beneficial Owners and Management of InterCAP."

     Certain Interests of Other Employees

     In connection with the Merger, Intergraph also has required that seven
employees of InterCAP other than Biddle, Gebhardt and Mills enter into
employment agreements with Intergraph Sub which will become binding upon
InterCAP as the Surviving Corporation in the Merger.  The affected employees
currently have no employment agreements with InterCAP.  Each employment
agreement provides for compensation and benefits at a rate or at levels equal to
such 

                                      -35-
<PAGE>
 
    
employees' compensation and benefits in effect at the time of the Merger.
Each agreement has a two year term and contains non-competition provisions which
are effective for one year after termination of employment.  None of the
InterCAP employees entering into such employment agreements (other than Biddle,
Gebhardt and Mills) is a director of InterCAP or was involved in the Board of
Directors' evaluation of the Merger.     

     Finally, the Reorganization Agreement provides that all employees of
InterCAP will be credited for their years of service at InterCAP for purposes of
employee welfare and pension benefit plans maintained for employees of
Intergraph and its affiliates, including the Surviving Corporation.  This
provision is applicable to all employees continuing in their employment with
InterCAP following the Merger, including Biddle, Gebhardt and Mills.

     Interests of Certain Parties to the Preferred Stock Agreement

     The signatories to the Preferred Stock Agreement (other than InterCAP) are
Venture First II L.P. ("Venture First"), Geocapital II L.P. ("Geocapital") and
Biddle.  W. Andrew Grubbs, one of the directors of InterCAP, is a general
partner of the sole general partner of Venture First, and Venture First is the
beneficial owner of 36,260 shares of InterCAP Common Stock, 915,340 shares of
InterCAP Series A Preferred Stock, and 1,677,630 shares of InterCAP Series B
Preferred Stock.  James Harrison, one of the directors of InterCAP, is a general
partner of Geocapital, and Geocapital is the beneficial owner of 953,442 shares
of InterCAP Series C Preferred Stock.  See "Security Ownership of Certain
Beneficial Owners and Management of InterCAP."  Messrs. Grubbs and Harrison have
no material interest in the Merger other than the respective interests of
Venture First and Geocapital as stockholders of InterCAP.  Mr. Biddle's
interests in the Merger are separately described above.


Certain Federal Income Tax Considerations

     The following discussion summarizes certain federal income tax consequences
of the Merger to Intergraph, Intergraph Sub, InterCAP and the InterCAP
stockholders relating to the Merger.  This discussion does not address other
federal income tax considerations that may be relevant to particular InterCAP
stockholders in light of their particular circumstances, such as dealers in
securities, stockholders who do not hold their InterCAP Stock as capital assets,
foreign persons or persons who acquired their shares in compensatory
transactions.

     In addition, the following discussion does not address the tax consequences
of transactions effectuated prior or subsequent to, or concurrently with, the
Merger (whether or not any such transactions are undertaken in connection with
the Merger).  Without limiting the generality of the immediately preceding
sentence, the following discussion does not address the tax consequences of the
assumption by Intergraph of the outstanding InterCAP Options, the award or
exercise of any InterCAP Options, the federal income tax characterization of the
InterCAP Options as nonqualified or qualified incentive stock options, or the
issuance or exercise of the InterCAP Warrants.

                                      -36-
<PAGE>
 
     ACCORDINGLY, INTERCAP STOCKHOLDERS ARE URGED TO CONSULT THEIR OWN TAX
ADVISORS AS TO THE SPECIFIC TAX CONSEQUENCES OF THE MERGER, INCLUDING THE
APPLICABILITY OF FEDERAL, STATE, LOCAL, AND FOREIGN TAX LAWS.

     No party to the Merger has requested a ruling from the Internal Revenue
Service (the "Service") with regard to the federal income tax consequences of
the Merger.  This discussion reflects, and is supported by, opinions of Balch &
Bingham, special counsel to Intergraph, and Womble Carlyle Sandridge & Rice,
P.L.L.C., counsel to InterCAP (collectively, the "Exhibit Opinions").  The
Exhibit Opinions, which are attached as Exhibit 8(a) and Exhibit 8(b),
respectively, to the Registration Statement of which this Prospectus/Proxy
Statement is a part, are based on and subject to certain qualifications and
assumptions as noted therein. InterCAP stockholders should be aware that this
discussion and the Exhibit Opinions are based upon counsel's interpretation of
the Internal Revenue Code of 1986, as amended (the "Code"), applicable United
States Department of Treasury ("Treasury") regulations, judicial authority and
administrative rulings and practice, all as of the date thereof. InterCAP
stockholders also should specifically note that the Exhibit Opinions contain an
especially important qualification concerning the Code's requirement that the
Merger involve a "continuity of proprietary interest." See "The Merger and
Related Transactions--Certain Federal Income Tax Considerations--Limitations on
Opinions and Discussions--Continuity of Interest Limitation." The opinions are
not binding on the Service and there can be no assurance that future
legislative, judicial or administrative changes or interpretations will not
adversely affect the accuracy of the statements and conclusions set forth
herein. Any such changes or interpretations could be applied retroactively and
could affect the tax consequences of the Merger.

     Consequences to Intergraph, Intergraph Sub and InterCAP

     The Merger as described in the Reorganization Agreement will constitute a
reorganization as defined in (S)368(a)(1)(A) of the Code by virtue of the
application of (S)368(a)(2)(E) of the Code.  No gain or loss will be recognized
by Intergraph, Intergraph Sub or InterCAP upon Intergraph's issuance of
Intergraph Common Stock solely in exchange for InterCAP Stock and the transfer
by operation of law of Intergraph Sub's assets and liabilities to InterCAP upon
consummation of the Merger.

     InterCAP's taxable year will end for federal income tax purposes on the
date of the Merger, and InterCAP will be required to file a federal income tax
return for its short taxable year ending on the date of the Merger.

     As a result of the Merger, InterCAP will experience an ownership change as
defined in (S)382(g) of the Code with the result that any InterCAP tax credit
carryforwards, net operating loss carryforwards, capital loss carryforwards or
built-in deductions will become subject to the limitations on use provided by
(S)(S)382 and 383 of the Code.  In addition, Intergraph's acquisition of
InterCAP in the Merger will result in the imposition of certain consolidated
return limitations on the ability of the Intergraph consolidated return group to
utilize any InterCAP tax credit 

                                      -37-
<PAGE>
 
carryforwards, net operating loss carryforwards, capital loss carryforwards or
built-in deductions pursuant to the Treasury regulations under (S) 1502 of the
Code.

     Consequences to InterCAP Stockholders

     No gain or loss will be recognized by holders of InterCAP Stock upon their
receipt in the Merger of Intergraph Common Stock in exchange therefor (except to
the extent of cash received in lieu of a fractional share of Intergraph Common
Stock).

     The aggregate tax basis of Intergraph Common Stock received in the Merger
(including any fractional share deemed received) will be the same as the
aggregate tax basis of the InterCAP Stock surrendered in exchange therefor.

     The holding period for federal income tax purposes of each share of
Intergraph Common Stock received by each InterCAP stockholder in the Merger will
include the period during which such stockholder held his or her InterCAP Stock
surrendered in exchange therefor, provided that the InterCAP Stock is held as a
capital asset at the time of the Merger.

     Cash payments in lieu of a fractional share will be treated as if a
fractional share of Intergraph Common Stock had been issued in the Merger and
then redeemed by Intergraph.  An InterCAP stockholder receiving such cash will
recognize gain or loss upon such payment equal to the difference (if any)
between such stockholder's basis in the fractional share (which will be a pro
rata portion of the stockholder's basis in the Intergraph Common Stock received
in the Merger) and the amount of cash received.

     A recipient of shares of Intergraph Common Stock could recognize income to
the extent that such shares were considered by the Service to be received in
exchange for consideration other than InterCAP Stock, such as dividends accrued
on such InterCAP Stock.  All or a portion of such income may be taxable as
ordinary income.

     Limitations on Opinions and Discussions

     General Limitations.  As a condition to the Merger, each of Intergraph and
     -------------------                                                       
InterCAP will receive an opinion from its respective counsel dated as of the
closing of the Merger to the effect that the Merger will constitute a
reorganization as defined in (S) 368(a) of the Code.  Such opinions (the
"Closing Opinions") will also be based on certain assumptions and subject to
certain qualifications similar to those contained in the Exhibit Opinions.
InterCAP stockholders should be aware that neither the Exhibit Opinions nor the
Closing Opinions bind the Service and the Service is therefore not precluded
from successfully asserting a contrary opinion.  In addition, as noted earlier,
all the tax opinions are subject to certain assumptions, including, but not
limited to, the truth and accuracy of certain representations made by
Intergraph, InterCAP and certain stockholders of InterCAP.  Of particular
importance to the opinion that the Merger will be treated as a tax-free
reorganization for federal income tax purposes are (i) certain assumptions and
representations relating to the Code's "continuity of interest" requirement, and
(ii) the fact that 

                                      -38-
<PAGE>
 
the opinion on this issue as it relates to certain contemplated distributions by
limited partnership stockholders of InterCAP (which are described below) is not
free from doubt and is subject to some legal uncertainty, as discussed below.
See "The Merger and Related Transactions--Tax Certification" and "--Certain
Federal Income Tax Consequences--Limitations on Opinions and Discussions--
Continuity of Interest Limitation.

     Continuity of Interest Limitation.  In order to satisfy the continuity of
     ---------------------------------                                        
interest requirement, InterCAP stockholders must not, pursuant to a plan or
intent existing at or prior to the Merger, sell, transfer, pledge or otherwise
dispose of an aggregate amount of (i) their InterCAP Stock in anticipation of
the Merger and (ii) Intergraph Common Stock to be received in the Merger
(collectively, "Planned Dispositions"), such that InterCAP stockholders, as a
group, would no longer have a meaningful equity interest in the InterCAP
business being conducted by Intergraph after the Merger. InterCAP stockholders
generally will be regarded as having a meaningful equity interest as long as the
number of shares of Intergraph Common Stock received in the Merger less the
number of shares subject to Planned Dispositions (if any) represents, in the
aggregate, a continuing interest through stock ownership in Intergraph that is
equal in value, as of the Effective Date, to more than 50% of the value of all
of the formerly outstanding InterCAP Stock as of the same date. The consummation
of the Merger therefore is conditioned upon receipt by Intergraph and InterCAP
of Continuity Certificates (as hereinafter defined), which cover at least 50% of
the Intergraph Common Stock to be issued in the Merger. The Continuity
Certificates require stockholders of InterCAP immediately prior to the Merger to
confirm that, as of the Effective Date of the Merger, they have no present plan
or intent to engage in a Planned Disposition of all or a specified portion of
the shares of Intergraph Common Stock received in the Merger. The form of the
Continuity Certificate to be executed by an entity stockholder of InterCAP
permits such entity to distribute shares of Intergraph Common Stock to the
partners, stockholders or other beneficial owners of the entity if such
distribution is required under the entity's partnership agreement, certificate
or articles of incorporation or other governing instrument. See "The Merger and
Related Transactions--Tax Certification."
    
     Two of the InterCAP stockholders hold approximately 98.6% of the InterCAP
Preferred Stock, and 54.7% of the outstanding InterCAP Preferred Stock and
InterCAP Common Stock taken together, and will receive approximately 58.8% of
the Closing Merger Consideration.  These two InterCAP stockholders are limited
partnerships, and one of them (which owns 100% of the InterCAP Series C
Preferred Stock and will receive approximately 13.4% of the  Closing Merger
Consideration) is required under its partnership agreement to distribute to its
partners the shares of Intergraph Common Stock to be received by such entity in
the Merger (the "Required Distributions").  The other such partnership
stockholder (which will receive approximately 45.4% of the Closing Merger
Consideration) is not required to make Required Distributions and has advised
InterCAP that it presently intends to hold the shares of Intergraph Common Stock
received by such partnership in the Merger.  Although the matter is not entirely
free from doubt, the Required Distributions should not be construed as Planned
Dispositions, such that the InterCAP stockholders, as a group, would no longer
have a meaningful continuing equity interest in the InterCAP business being
conducted by Intergraph after the Merger.  Although the Exhibit      

                                      -39-
<PAGE>
 
Opinions address, and the Closing Opinions will address, whether the Required
Distributions would constitute a Planned Disposition (and thus cause the Merger
to fail the Code's continuity of proprietary interest requirement and fail to
constitute a reorganization), the Exhibit Opinions address (and the Closing
Opinions will address) this issue with the qualification that the issue is not
free from doubt because (i) available tax authorities address the issue in the
context of distributions by corporations, not partnerships, (ii) counsel was
unable to locate any published tax authorities involving distributions by
partnerships, and (iii) the Service at one time took a contrary position in the
corporate context but subsequently reversed that position in 1984. Counsel's
opinion that any Required Distributions by InterCAP's limited partnership
stockholders "should not violate the continuity of proprietary interest
requirement" should be viewed by InterCAP stockholders as an explained or
reasoned opinion on that issue which reflects counsel's professional judgment
but acknowledges the existence of legal uncertainty under the applicable tax
authorities.
    
     Effect of Failure to Qualify as Tax-Free Reorganization.  A successful
     -------------------------------------------------------               
challenge by the Service to the tax-free reorganization status of the Merger (as
a result of a failure of the continuity of interest requirement or otherwise)
would result in InterCAP stockholders recognizing taxable gain or loss with
respect to each share of InterCAP Stock surrendered equal to the difference
between the stockholder's basis in such share and the fair market value, as of
the Effective Date, of the Intergraph Common Stock and Intergraph Rights
received in exchange therefor.  In such event, a stockholder's aggregate basis
in Intergraph Common Stock so received would equal its fair market value at the
Effective Date and the holding period for such stock would begin on the day
after the Effective Date.     


Preferred Stock Agreement

     In connection with the execution of the Reorganization Agreement and as a
condition to its obligation to consummate the Merger, Intergraph required that
the Preferred Stock Agreement be executed by the holders of all of the InterCAP
Series A Preferred Stock, all of the InterCAP Series C Preferred Stock, and
98.85% of the InterCAP Series B Preferred Stock (collectively, the "Specified
Preferred Stockholders").  Pursuant to the Preferred Stock Agreement, the
Specified Preferred Stockholders have agreed (i) to vote all of their shares of
InterCAP Stock in favor of approving the Charter Amendment, (ii) in the case of
holders of InterCAP Series A Preferred Stock, to elect to take the liquidation
preference of $1.475 per share of InterCAP Series A Preferred Stock, (iii) to
exercise the Warrant (as defined herein) in full immediately prior to the
Effective Date in the manner contemplated by the Preferred Stock Agreement, (iv)
in the case of the holders of the remaining classes of InterCAP Preferred Stock,
to elect to convert all of such InterCAP Series B Preferred Stock and InterCAP
Series C Preferred Stock into InterCAP Common Stock prior to the consummation of
the Merger, and (v) that the receipt of a fraction of a share of Intergraph
Common Stock with a value of $1.475 per share of InterCAP Series A Preferred
Stock and the receipt of a fraction of a share of Intergraph Common Stock with a
value of $0.90975693 per share of InterCAP Common Stock upon the conversion of
the InterCAP 

                                      -40-
<PAGE>
 
Series B Preferred Stock and InterCAP Series C Preferred Stock shall be in
complete and full satisfaction of all rights and preferences attendant to such
InterCAP Preferred Stock.
    
     By separate letter agreement dated December 7, 1994 the Specified Preferred
Stockholders also agreed to postpone the effective date of the InterCAP 
Redemption Obligations relating to their InterCAP Preferred Stock from January 
2, 1995 until January 16, 1995 in order to permit the extension of the Merger 
Termination Date from December 31, 1994 until January 15, 1995.      

     In the absence of the adoption and approval of the Charter Amendment
contemplated by the Preferred Stock Agreement, the liquidation preference of
$1.475 for each share of InterCAP Series A Preferred Stock would have adjusted
as of October 1, 1994 to approximately $1.91 for each share of InterCAP Series A
Preferred Stock and would increase thereafter on a daily basis at an annual rate
per share of $.07375.  Under the terms of the InterCAP Certificate, a
consolidation or merger of InterCAP of the kind contemplated by the
Reorganization Agreement constitutes a "liquidation, dissolution or winding up"
that triggers the right of the holders of InterCAP Series A Preferred Stock to
receive the foregoing liquidation preference.  The effect of the Charter
Amendment is to modify the date (by changing such date from October 1, 1994 to
January 15, 1995) upon which the foregoing adjustment to the liquidation
preference otherwise would occur. See "Proposal to Amend InterCAP's Certificate
of Incorporation."

     As of the Record Date, the 408,586 shares of InterCAP Common Stock and
3,886,835 shares of InterCAP Preferred Stock subject to the Preferred Stock
Agreement represented approximately 63.00% of the voting power outstanding of
InterCAP Common Stock and InterCAP Preferred Stock, taken together as a single
class, and 99.5% of the outstanding InterCAP Preferred Stock.  Accordingly, the
Charter Amendment will be approved and adopted by InterCAP's stockholders at the
Meeting even if no other stockholder of InterCAP votes in favor of the Charter
Amendment.

     Although the Specified Preferred Stockholders have agreed pursuant to the
Preferred Stock Agreement to vote all their shares of InterCAP Stock in favor of
the Charter Amendment, they have not agreed to vote their shares of InterCAP
Stock in favor of approval of the Reorganization Agreement and the Merger
because Intergraph did not ask them to do so.  Accordingly, each of the
Specified Preferred Stockholders is free to vote his or its shares of InterCAP
Stock in favor of or against approval of the Merger, or to refrain from voting
at all with respect to the Merger.  Each of the directors of InterCAP, however,
including Mr. Biddle who is a Specified Preferred Stockholder and Messrs. Grubbs
and Harrison, who are general partners of venture capital funds that are the
other  Specified Preferred Stockholders, has indicated that he currently intends
to vote all shares of InterCAP Stock over which he exercises voting control in
favor of the Merger.  Although it is possible that a subsequent event, such as
an offer to acquire InterCAP from a third party that is perceived to be superior
to the proposed Merger with Intergraph, could cause one or more of the Specified
Preferred Stockholders to decide to vote against the Merger, InterCAP believes
that the occurrence of such an event would necessarily require reconsideration
by the Board of the Merger as a whole and the Board's recommendations to the
InterCAP stockholders with respect thereto.  See "The Merger and Related
Transactions--Effect on InterCAP if Merger is not Approved."

Escrow Agreement

     Under the terms of the Reorganization Agreement and the Escrow Agreement,
at the Effective Date, Intergraph will deliver to the Escrow Agent one or more
certificates representing the Escrow Shares.  By virtue of InterCAP stockholder
approval of the Reorganization Agreement, a committee of three!persons,
initially represented by A.G.W. Biddle, III, John C. Gebhardt and Joy E.
Binford, will be appointed to represent the InterCAP stockholders (the
"Stockholders' Committee").  The Escrow Shares will secure the InterCAP
stockholders' indemnification obligations with respect to the representations
and warranties made by InterCAP in the Reorganization Agreement.  The Escrow
Shares will remain in escrow until the ninetieth day after the Effective Date,
at which time the Escrow Agent will distribute the remaining Escrow Shares which
are not then subject to pending or disputed claims by indemnified person(s)
under the Escrow Agreement, if any, to the InterCAP stockholders in the manner
described in the Escrow Agreement. No distribution to the InterCAP stockholders
will be made, however, if there has been a claim delivered to the Escrow Agent
by an indemnified person(s), the claim has not been settled or discharged, and
the balance of the Escrow Shares after distribution, if the indemnified
person(s) prevailed on such claim, would be insufficient to discharge the claim.
At the request of the Stockholders' Committee at any time prior to the end of
the ninety day escrow period, the Escrow Agent is required to distribute the
portion of the Escrow Fund that is attributable to each InterCAP stockholder on
whose behalf 30 or fewer shares of Intergraph Common Stock were initially
contributed to the Escrow. 

     The InterCAP stockholders have the right to vote the Escrow Shares while
such shares are in escrow, but they will not have the right to sell the Escrow
Shares while in escrow, regardless of any changes in the stock price of the
Escrow Shares. Dividends or other distributions with respect to the Escrow
Shares, if any, would be placed in the escrow account and distributed together
with such Escrow Shares in accordance with the terms of the Escrow Agreement.
The Escrow Agreement may be terminated at any time upon receipt by the Escrow
Agent of 10 days' prior written notice of termination executed by Intergraph and
the Stockholders' Committee directing the distribution of all property then held
by the Escrow Agent. See "Risk Factors."


Options Outstanding Prior to the Merger

     InterCAP Option Plan

     On March 2, 1989, InterCAP adopted the InterCAP 1989 Stock Option Plan (the
"InterCAP Option Plan").  The InterCAP Option Plan authorized the issuance of
incentive stock options within the meaning of Section 422 of the Code, as well
as options not qualifying as incentive stock options.  Options under the
InterCAP Option Plan could be issued to employees or officers of or consultants
to InterCAP or its subsidiaries.  As of September 30, 1994, the Board of
Directors of InterCAP had granted outstanding options denominated as incentive
stock options 

                                      -42-
<PAGE>
 
to acquire 935,062 shares of InterCAP Common Stock, and options to acquire
1,173,376 shares of InterCAP Common Stock had been exercised or terminated.

     InterCAP Option Program

     The Board of Directors of InterCAP, pursuant to a resolution adopted on
March 1, 1991, authorized the grant of options for shares of InterCAP Common
Stock remaining for grant under the InterCAP Option Plan in the event of a
change of control or sale of InterCAP, such grant to be made on a pro rata basis
to the holders of outstanding options under the InterCAP Option Plan at the
weighted average exercise price of options then outstanding under the InterCAP
Option Plan.  In adopting this resolution, the Board of Directors of InterCAP
determined that the value, if any, of the authorized options available for grant
under the InterCAP Option Plan should inure to the benefit of InterCAP's
employees in the event of a change in control or sale of InterCAP.  Because the
InterCAP Option Plan prohibits the issuance thereunder of options (including
nonqualified options) at exercise prices that are below the fair market value of
a share of InterCAP Common Stock at the date of grant, the Board of Directors of
InterCAP determined that the March 1, 1991 resolution could not be implemented
through use of the InterCAP Option Plan. As a result, by resolution adopted on
September 26, 1994, the InterCAP Board of Directors rescinded the March 1, 1991
resolution and released from reservation under the InterCAP Option Plan the
391,562 shares that remained available for option grants thereunder. Concurrent
with this action, the InterCAP Board of Directors, by resolution approved on
September 26, 1994, adopted the InterCAP 1994 Nonqualified Stock Option Program
(the "InterCAP Option Program") and reserved up to a maximum of 391,562 shares
of InterCAP Common Stock for issuance upon exercise of NQSO's issued under the
InterCAP Option Program. Finally, on September 26, 1994, all available options
under the InterCAP Option Program were granted to various employees and officers
of InterCAP in a manner consistent with the original March 1, 1991 resolution,
conditioned upon consummation of the Merger. The InterCAP ISO's and NQSO's are
collectively referred to as the "InterCAP Options."

     ISO Agreements

     To evidence option grants made under the InterCAP Option Plan, InterCAP has
entered into agreements denominated as incentive stock option agreements (the
"ISO Agreements") with various employees (each, an "Optionee").  Under the terms
of each ISO Agreement, InterCAP has granted ISO's to each Optionee in
consideration of the continued service of the Optionee.  Under the InterCAP
Option Plan, the ISO's are periodically exercisable at the option price
specified in the ISO Agreement, but they must be exercised within ten years from
the date of issue.  The ISO's generally are only exercisable, however, if the
Optionee has remained in continuous employment with InterCAP from the date of
grant until the date of the proposed exercise.  The shares of InterCAP Common
Stock acquired upon the exercise of the ISO are not covered by a registration
statement under the Securities Act or under any state securities laws.  In
general, the ISO's terminate upon the termination of service of the Optionee as
an officer or employee of InterCAP.  If the Optionee ceases to be an employee of
InterCAP within three years after the date of grant, InterCAP has the right to
repurchase all shares of InterCAP Common 

                                      -43-
<PAGE>
 
Stock acquired by the Optionee pursuant to the ISO Agreements, under the terms
and conditions as specified in such ISO Agreement.

     Although the ISO Agreements generally provide for incremental vesting of
each ISO, the ISO Agreements also provide for accelerated vesting in the event
of certain change-in-control transactions affecting InterCAP.  The Merger
constitutes such a transaction, and accordingly, all ISO's, whether or not then
fully vested, will be fully vested by virtue of the Merger.

     The Reorganization Agreement provides for the assumption by Intergraph of
each ISO upon the terms set forth in the ISO Agreements, except for (i) the
deletion of provisions which by their nature are not applicable to Intergraph or
the Intergraph Common Stock, or provisions which have been rendered inapplicable
by the passage of time, and (ii) adjustment of the number of shares covered by
the ISO and the exercise price as discussed under "The Reorganization 
Agreement--InterCAP Options."

     Nonqualified Stock Option Agreements

     Under the terms of the InterCAP Option Program and the Nonqualified Stock
Option Agreements entered into in connection with the grant of NQSO's thereunder
(the "NQSO Agreements"), InterCAP has granted to certain Optionees NQSO's in
recognition of past service to InterCAP and to induce the Optionees to remain in
the employ of InterCAP following the Merger.  The effectiveness of the grant is
conditional on and subject to the consummation of the Merger.  If the Merger is
consummated pursuant to the Reorganization Agreement, the grant shall be deemed
to have been made immediately before the consummation of the Merger.  The NQSO's
are periodically exercisable at the exercise price specified in each NQSO
Agreement, but they must be exercised within ten years from the date of issue.
The NQSO's generally are only exercisable, however, if the Optionee has remained
in continuous employment with InterCAP from the date of the NQSO Agreement until
the date of the proposed exercise.

     The NQSO Agreements provide that each NQSO will be 50% vested upon
consummation of the Merger, and that an additional 25% of each such NQSO will
vest annually on the two succeeding anniversaries of the Effective Date.  The
NQSO Agreements also provide for (i) accelerated vesting of each NQSO and a
ninety day exercise window in the event the Optionee's employment by the
Surviving Corporation is terminated for a reason other than cause, and (ii)
accelerated vesting of each NQSO and a one year exercise window in the event of
death of the Optionee.  As required by Biddle's 1990 employment agreement with
InterCAP, the NQSO granted to Biddle under the InterCAP Option Program with
respect to 80,724 shares of InterCAP Common Stock will be fully vested at the
Effective Date and Biddle will be permitted to exercise such NQSO for a period
of five years from the Effective Date, whether or not Biddle is then an employee
of the Surviving Corporation.

     The Reorganization Agreement provides for the assumption by Intergraph of
each NQSO upon the terms set forth in the NQSO Agreements, except for adjustment
of the number of shares 

                                      -44-
<PAGE>
 
covered by the option and the exercise price as discussed under "The
Reorganization Agreement--InterCAP Options."


Governmental and Regulatory Approvals

     Intergraph and InterCAP are aware of no governmental or regulatory
approvals required for consummation of the Merger, other than compliance with
the Securities Act and applicable state securities and "blue sky" laws.


Tax Certification

     Consummation of the Merger is conditioned upon receipt by Intergraph and
InterCAP of certificates executed by holders of the InterCAP Stock, and covering
at least 50% of the Intergraph Common Stock to be issued in the Merger (the
"Continuity Certificates").  The Continuity Certificates require the
stockholders of InterCAP immediately prior to the Merger to confirm that, as of
the Effective Date, they have no present plan or intent to engage in a sale,
exchange, transfer, pledge or other disposition of all or a specified portion of
the shares of Intergraph Common Stock received in the Merger. The specified
portion referred to in the certificates may vary, but the obligations of
InterCAP and Intergraph to consummate the Merger are conditioned upon the
receipt of Continuity Certificates confirming as of the Effective Date that the
holders of InterCAP Stock do not, when viewed as a group, have a present plan or
intent to sell, exchange, transfer, pledge or otherwise dispose of more than 50%
of the Intergraph Common Stock received in the Merger. The form of the
Continuity Certificate to be executed by an entity stockholder of InterCAP
permits such entity to distribute shares of Intergraph Common Stock to the
partners, shareholders or other beneficial owners of the entity if such
distribution is required under the entity's partnership agreement, certificate
or articles of incorporation or other governing instrument. However, the entity
is required to confirm as of the Effective Date that, to the best knowledge of
the entity after due inquiry, there is no present plan or intent on the part of
the recipients of the required distribution to engage in a sale, exchange,
transfer, pledge or other disposition of the portion of the shares of Intergraph
Common Stock to be received by the recipients as specified in the Continuity
Certificate. Among other assumptions, the Exhibit Opinions and the Closing
Opinions concerning the tax consequences of the Merger will rely on, and assume
the accuracy of, the Continuity Certificates.


Employment Agreements

     Intergraph Sub has entered into employment agreements with ten key
employees of InterCAP.  The effectiveness of these agreements is conditioned
upon consummation of the Merger.  In general, these agreements provide, among
other things, for the continued employment of the employees at their pre-Merger
salary, bonus and benefit levels for a period of two years from the Effective
Date (unless the agreements are terminated under particular circumstances), 

                                      -45-
<PAGE>
 
and obligate the employees under non-competition agreements for a period of one
year following termination of employment. In the case of the Biddle-Intergraph
Employment Agreement, Biddle's employment by the Surviving Corporation would
continue at his pre-Merger salary, bonus and benefit levels for a period of
three months from the Effective Date (unless the agreement is terminated under
particular circumstances), and Biddle would be obligated under a non-competition
agreement for a period of two years following termination of employment. The
Biddle-Intergraph Employment Agreement also reaffirms the change-in-control
payment of $167,000 due to Biddle following the Merger in accordance with his
1990 employment agreement with InterCAP. See "The Merger and Related
Transactions--Interests of Certain Persons in the Merger."

     In addition, Intergraph has agreed in the Reorganization Agreement that for
so long as InterCAP remains profitable (but in no event for a period longer than
one year from the Effective Date), (i) the salaries of InterCAP employees will
not be generally reduced as part of any Intergraph-wide reduction of employee
compensation, and (ii) the employees of InterCAP will not be subject to any
Intergraph-wide layoffs or reductions in force.  Nonetheless, all InterCAP
employees will remain employees at will (unless otherwise agreed in writing by
Intergraph), and Intergraph may generally reduce the InterCAP work force
(otherwise than as part of an Intergraph-wide layoff or reduction in force) if
it determines in its sole discretion to do so based on the business conditions,
cost structure and results of operations of InterCAP.  See "The Merger and
Related Transactions--Interests of Certain Persons in the Merger."


Accounting Treatment

     The Merger is expected to be accounted for by the purchase method for
financial accounting purposes.  Under this method of accounting, the assets and
liabilities of InterCAP will be accounted for at cost.  Cost is determined by
reference to the fair value of the net assets acquired or the fair value of the
consideration given. Accordingly, the assets of InterCAP will be recorded at the
fair value of the Intergraph Common Stock received in the Merger and the Assumed
Option Spread (a total of $7.5 million).  Income of the combined company will
include income of InterCAP from the date of the Merger forward and income of
Intergraph for the entire fiscal year in which the combination occurs.  See "The
Reorganization Agreement--Conditions to the Merger."


Dissenters' Rights

     Holders of InterCAP Stock are entitled to appraisal rights under Section
262 of the Delaware Act.  A person having a beneficial interest in shares of
InterCAP Stock held of record in the name of another person, such as a broker or
nominee, must act promptly to cause the record holder to follow the steps
summarized below properly and in a timely manner to perfect whatever appraisal
rights the beneficial owner may have.

                                      -46-
<PAGE>
 
     The following discussion is not a complete statement of the law pertaining
to appraisal rights under the Delaware Act and is qualified in its entirety by
the full text of Section 262 which is reprinted in its entirety as Appendix C to
this Prospectus/Proxy Statement.  All references in Section 262 and in this
summary to a "stockholder" are to the record holder of the shares of InterCAP
Stock as to which appraisal rights are asserted.

     Under the Delaware Act, holders of shares of InterCAP Stock who follow the
procedures set forth in Section 262 will be entitled to have their shares of
InterCAP Stock appraised by the Delaware Court of Chancery and to receive
payment of the "fair value" of such shares, exclusive of any element of value
arising from the accomplishment or expectation of the Merger, together with a
fair rate of interest, as determined by such court.

     Under Section 262, at least 20 days prior to the Meeting (as hereinafter
defined), InterCAP must notify each of its stockholders entitled to appraisal
rights that such appraisal rights are available and include in such notice a
copy of Section 262.  This Prospectus/Proxy Statement shall constitute such
notice to the holders of shares of InterCAP Stock and a copy of Section 262
is attached to this Prospectus/Proxy Statement as Appendix C.  Any InterCAP
stockholder who or which wishes to exercise such appraisal rights or who or
which wishes to preserve his or its right to do so should review the following
discussion and Appendix C carefully because failure to comply timely and
properly with the procedures specified will result in the loss of appraisal
rights under the Delaware Act.

     A holder of shares of InterCAP Stock wishing to exercise his or its
appraisal rights must deliver to InterCAP, prior to the taking of the vote on
the Merger at the Meeting, a written demand for appraisal of his or its shares
of InterCAP Stock and must not vote in favor of the approval and adoption of the
Reorganization Agreement and the Merger at the Meeting.  The failure to vote in
favor of the Reorganization Agreement and the Merger, or a vote in person or by
proxy against the Merger, will not in and of itself constitute a written demand
for appraisal satisfying the requirements of Section 262.  In addition, a holder
of shares of InterCAP Stock wishing to exercise his or its appraisal rights must
hold of record such shares on the date the written demand for appraisal is made
and must continue to hold such shares until the Effective Date.

     Only a holder of record of shares of InterCAP Stock is entitled to assert
appraisal rights for the shares of InterCAP Stock registered in that holder's
name.  A demand for appraisal should be executed by or on behalf of the holder
of record, fully and correctly, as his or its name appears on his or its stock
certificates.  If the shares of InterCAP Stock are owned of record in a
fiduciary capacity, such as by a trustee, guardian or custodian, execution of
the demand should be made in that capacity, and if the shares of InterCAP Stock
are owned of record by more than one person, as in a joint tenancy and tenancy
in common, the demand should be executed by or on behalf of all joint owners.
An authorized agent, including one or more joint owners, may execute a demand
for appraisal on behalf of a holder of record; however, the agent must identify
the record owner or owners and expressly disclose the fact that, in executing
the demand, the 

                                      -47-
<PAGE>
 
agent is agent for such owner or owners. All written demands for appraisal
should be sent or delivered to InterCAP at 116 Defense Highway, Suite 400,
Annapolis, Maryland 21401.

     Within ten days after the Effective Date, InterCAP will notify each holder
of InterCAP Stock who has complied with Section 262 and who has not voted in
favor of the Merger of the date the Merger became effective.

     Within 120 days after the Effective Date, but not thereafter, InterCAP or
any stockholder entitled to appraisal rights under Section 262 may file a
petition in the Delaware Court of Chancery demanding a determination of the fair
value of the shares of InterCAP Stock held by any such stockholders.  InterCAP
is under no obligation to and has no present intention to file a petition with
respect to the appraisal of the fair value of the shares of InterCAP Stock.
Accordingly, it is the obligation of the stockholders of InterCAP to initiate
all necessary action to perfect their appraisal rights within the time
prescribed in Section 262.

     Within 120 days after the Effective Date, any stockholder of InterCAP who
has complied with the requirement for exercise of appraisal rights will be
entitled, upon written request, to receive from InterCAP a statement setting
forth the aggregate number of shares of InterCAP Stock not voted in favor of the
approval and adoption of the Reorganization Agreement and the Merger and with
respect to which demands for appraisal have been received and the aggregate
number of holders of such shares. Such statement must be mailed to such
stockholder within ten days after a written request therefor has been received
by InterCAP or within ten days after the expiration of the period for delivery
of demands for appraisal by stockholders outlined above, whichever is later.

     If a petition for an appraisal is timely filed, after a hearing on such
petition, the Delaware Court of Chancery will determine the stockholders
entitled to appraisal rights and will appraise the "fair value" of their shares
of InterCAP Stock, exclusive of any element of value arising from the
accomplishment or expectation of the Merger, together with a fair rate of
interest, if any, to be paid upon the amount determined to be the fair value.
Stockholders considering seeking appraisal should be aware that the fair value
of their shares of InterCAP Stock as determined under Section 262 could be more
than, the same as or less than the consideration they would receive pursuant to
the Reorganization Agreement if they did not seek appraisal of their shares of
InterCAP Stock.  The Delaware Supreme Court has stated that "proof of value by
any techniques or methods which are generally considered acceptable in the
financial community and otherwise admissible in court" should be considered in
the appraisal proceedings.  In addition, Delaware courts have decided that the
statutory appraisal remedy, depending on factual circumstances, may or may not
be a dissenter's exclusive remedy.  The costs of the action may be determined by
the court and taxed upon the parties as the court deems equitable.  The court
may also order that all or a portion of the expenses incurred by any stockholder
in connection with an appraisal, including, without limitation, reasonable
attorneys' fees and the fees and expenses of experts utilized in the appraisal
proceeding, be charged pro rata against the value of all of the shares of
InterCAP Stock entitled to appraisal.

                                      -48-
<PAGE>
 
     Any holder of shares of InterCAP Stock who has duly demanded an appraisal
in compliance with Section 262 will not, after the Effective Date, be entitled
to vote the shares of InterCAP Stock subject to such demand for any purpose or
be entitled to the payment of dividends or other distributions on those shares
(except dividends or other distributions payable to holders of record of shares
of InterCAP Stock as of a date prior to the Effective Date).

     If any stockholder who demands appraisal of his or its shares of InterCAP
Stock under Section 262 fails to perfect, or effectively withdraws or loses, his
or its right to appraisal, as provided in the Delaware Act, the shares of
InterCAP Stock of such stockholder will be converted into the right to receive
shares of Intergraph Common Stock in accordance with the Reorganization
Agreement.  A stockholder will fail to perfect, or effectively lose or withdraw,
his or its right to appraisal if no petition for appraisal is filed within 120
days after the Effective Date, or if the stockholder delivers to InterCAP a
written withdrawal of his or its demand for appraisal and acceptance of the
Merger, except that any such attempt to withdraw made more than 60 days after
the Effective Date will require the written approval of InterCAP.

     Failure to follow the steps required by Section 262 of the Delaware Act for
perfecting appraisal rights may result in the loss of such rights, in which
event an InterCAP stockholder will be entitled to receive a fraction of a share
of Intergraph Common Stock for each share of InterCAP Stock owned by him or it
as follows: (a) each share of InterCAP Common Stock will be converted into the
right to receive a fraction of a share of Intergraph Common Stock having a value
of (determined prior to the Closing Date using the Share Determination Market
Price) $0.90975693, (b) each share of InterCAP Series A Preferred Stock will be
converted into the right to receive a fraction of a share of Intergraph Common
Stock having a value of $1.475, and (c) each share of InterCAP Series B
Preferred Stock and each share of InterCAP Series C Preferred Stock will be
converted into the right to receive a fraction of a share of Intergraph Common
Stock having a value of $0.90975693.


     STOCKHOLDERS ELECTING TO EXERCISE THEIR APPRAISAL RIGHTS UNDER SECTION 262
MUST NOT VOTE FOR APPROVAL OF THE MERGER.  A VOTE BY A STOCKHOLDER AGAINST
APPROVAL OF THE MERGER IS NOT REQUIRED IN ORDER FOR THAT STOCKHOLDER TO EXERCISE
APPRAISAL RIGHTS.  HOWEVER, IF A STOCKHOLDER RETURNS A SIGNED PROXY BUT DOES NOT
SPECIFY A VOTE AGAINST APPROVAL OF THE MERGER OR A DIRECTION TO ABSTAIN, THE
PROXY, IF NOT REVOKED, WILL BE VOTED FOR APPROVAL OF THE MERGER, WHICH WILL HAVE
THE EFFECT OF WAIVING THAT STOCKHOLDER'S APPRAISAL RIGHTS.

                          THE REORGANIZATION AGREEMENT

    
     The following is a brief summary of the Reorganization Agreement, which
(including the Reorganization Agreement Amendment and the exhibits to the
Reorganization Agreement) is attached as Appendix A to this Prospectus/Proxy
Statement and is incorporated herein by reference in its entirety. Such summary
is qualified in its entirety by reference to the Reorganization Agreement.     

Effective Date of the Merger
    
     If the Merger is approved by the stockholders of InterCAP and the other
conditions to the Merger are satisfied or waived, the Merger will become
effective upon the filing by Intergraph Sub and InterCAP of the Certificate of
Merger with the Secretary of State of the State of Delaware, in the manner
provided under Section 251 of the Delaware Act.  Assuming all conditions to the
Merger are met or waived prior thereto, it is anticipated that the Effective
Date will occur on or about January 12, 1995.      


Effects of the Merger

     Upon consummation of the Merger, Intergraph Sub will be merged with and
into InterCAP, with InterCAP surviving the Merger and becoming a wholly owned
subsidiary of Intergraph (the "Surviving Corporation").  The directors and
executive officers of Intergraph will remain unchanged as a result of the
Merger.  Upon consummation of the Merger, the members of the Surviving
Corporation's Board of Directors will be James W. Meadlock (Chief Executive
Officer and Chairman of the Board of Intergraph), Stephen J. Phillips (an
Executive Vice President of Intergraph) and Tommy D. Steele (an Executive Vice
President of Intergraph).  The officers of InterCAP in office immediately prior
to the Effective Date will no longer serve in such capacity and the officers of
the Surviving Corporation will be the officers of Intergraph Sub prior to the
Merger.  The officers of Intergraph Sub prior to the Merger will be James W.
Meadlock (Chief Executive Officer), Stephen J. Phillips (Executive Vice
President and Secretary), and Tommy D. Steele (Executive Vice President).  The
stockholders of InterCAP will become stockholders of Intergraph (as described
below), and their rights will be governed by Intergraph's Certificate of
Incorporation, Restated By-laws and the Stockholder Rights Plan.  See
"Description of Intergraph Capital Stock" and "Principal Differences Between
Intergraph and InterCAP Capital Stock."


Aggregate Merger Consideration

     Pursuant to the Reorganization Agreement, Intergraph will pay or furnish
total consideration having a value (based on the Share Determination Market
Price) of $7.5 million for the entire equity interest of InterCAP.  Such
consideration will be paid or furnished (i) by the 

                                      -50-
<PAGE>
 
conversion of the InterCAP Options into options to acquire Intergraph Common
Stock such that the Aggregate Assumed Option Spread of all options so converted
will be equal to $1,021,573.65, (ii) in the amount of the Closing Merger
Consideration by the issuance of shares of Intergraph Common Stock (and cash
payments in respect of fractional shares) in an amount equal to $7.5 million
minus the Aggregate Assumed Option Spread. The Closing Merger Consideration will
be allocated among the classes of InterCAP Stock according to the exchange
ratios described below. See "The Reorganization Agreement--Manner and Basis of
Converting InterCAP Stock." The precise number of shares of Intergraph Common
Stock issued to each stockholder of InterCAP will be determined prior to the
Effective Date based on the applicable exchange ratio and the Share
Determination Market Price. It is expected (assuming the Share Determination
Market Price were determined as of September 30, 1994 rather than the Effective
Date) that, upon consummation of the Merger, the holders of InterCAP Stock will
receive shares of Intergraph Common Stock representing approximately 1.57% of
the Intergraph Common Stock outstanding as of such time.


Manner and Basis of Converting InterCAP Stock

     Upon the consummation of the Merger, (a) each issued and outstanding share
of common stock of Intergraph Sub will be converted into one share of common
stock of the Surviving Corporation, (b) each share of InterCAP Stock that is
either, (i) authorized but unissued, (ii) owned by InterCAP as treasury stock,
or (iii) owned by any subsidiary of InterCAP will be cancelled, (c) each then
outstanding share of InterCAP Common Stock (other than shares held by dissenting
stockholders) will automatically be converted into the right to receive a
fraction of a share of Intergraph Common Stock having a value (determined prior
to the Closing Date using the Share Determination Market Price) of $0.90975693,
and (d) each then outstanding share of InterCAP Preferred Stock (other than
shares held by the dissenting stockholders) will be automatically converted into
the right to receive a fraction of a share of Intergraph Common Stock as
follows: (i) each share of InterCAP Series A Preferred Stock will be converted
into the right to receive a fraction of a share of Intergraph Common Stock
having a value (determined prior to the Closing Date using the Share
Determination Market Price) of $1.475, (ii) each share of InterCAP Series B
Preferred Stock, if any, will be exchanged and converted into the right to
receive a fraction of a share of Intergraph Common Stock having a value
(determined prior to the Closing Date using the Share Determination Market
Price) of $0.90975693, (iii) each share of InterCAP Series C Preferred Stock, if
any, will be exchanged and converted into the right to receive a fraction of a
share of Intergraph Common Stock having a value (determined prior to the Closing
Date using the Share Determination Market Price) of $0.90975693.  Additionally,
each share of Intergraph Common Stock to be issued upon conversion of shares of
InterCAP Stock in accordance with the Reorganization Agreement will include the
corresponding percentage of a right (the "Intergraph Rights") to purchase
"Common Shares" pursuant to and as defined in the Rights Agreement dated August
25, 1993 by and between Intergraph and Harris Trust and Savings Bank, an
Illinois banking corporation (the "Intergraph Rights Agreement").  See
"Description of Intergraph Capital Stock--Stockholder Rights Plan."

     If upon a consummation of the Merger, any holder of InterCAP Stock would be
entitled to receive a number of shares of Intergraph Common Stock that includes
a fraction, then in lieu of a fractional share, such holder will be entitled to
receive cash equal to $0.90975693 multiplied by the fraction of a share of
Intergraph Common Stock to which the stockholder would otherwise be entitled.

     Based upon the capitalization of InterCAP and Intergraph as of September
30, 1994, and the exchange ratios set forth above (and assuming the Share
Determination Market Price were determined as of September 30, 1994 rather than
at the Effective Date), the stockholders of InterCAP will own Intergraph Common
Stock representing approximately 1.57% of the Intergraph Common Stock
outstanding immediately after consummation of the Merger.

     As promptly as practicable after the Effective Date, the Exchange Agent
will mail the Letter of Transmittal to each holder of record of InterCAP Stock
as of the Effective Date.  The Letter of Transmittal will contain information
and instructions with respect to the surrender of InterCAP share certificates in
exchange for new certificates representing shares of Intergraph Common Stock
(other than the Escrow Shares to be delivered into escrow on behalf of such
holder pursuant to the terms of the Reorganization Agreement) (each, an
"Intergraph Certificate") and cash payment for any fractional shares resulting
from the exchange. INTERCAP SHARE CERTIFICATES SHOULD NOT BE SURRENDERED UNTIL
THE LETTER OF TRANSMITTAL IS RECEIVED.

     In the event of a transfer of ownership of shares of InterCAP Stock which
is not registered on the transfer records of InterCAP, an Intergraph Certificate
representing the proper number of shares of Intergraph Common Stock may be
issued to a transferee if the InterCAP Certificate representing such InterCAP
Stock is presented to Intergraph, accompanied by all documents required to
evidence and effect such transfer and by evidence that any applicable stock
transfer taxes have been paid.  Until surrendered to Intergraph, each InterCAP
Certificate will be deemed, on and after the Effective Date, to represent only
the right to receive upon such surrender Intergraph Certificates representing
shares of Intergraph Common Stock (other than the Escrow Shares) and cash, if
any, in lieu of a fractional share of Intergraph Common Stock to which such
holder has become entitled.

INTERCAP CERTIFICATES SHOULD NOT BE SURRENDERED BY THE HOLDERS OF INTERCAP STOCK
TO INTERGRAPH UNTIL A LETTER OF TRANSMITTAL IS RECEIVED AFTER THE EFFECTIVE DATE
OF THE MERGER.


InterCAP Options

     Pursuant to the Reorganization Agreement, each outstanding InterCAP Option
will be assumed by Intergraph and automatically converted into an option to
purchase shares of Intergraph Common Stock (the "Assumed Options").  Each
InterCAP Option so assumed by Intergraph will be exercisable for a number of
shares of Intergraph Common Stock determined 

                                      -52-
<PAGE>
 
by multiplying the number of shares of InterCAP Common Stock subject to the
InterCAP Option by the fraction resulting from (i) dividing $0.90975693 by (ii)
the Share Determination Market Price (the resulting fraction of which is the
"Option Conversion Fraction"), at an exercise price equal to the exercise price
of the InterCAP Option at the time of the Merger divided by the Option
Conversion Fraction. Each Assumed Option will have the same terms and
conditions, including the same term, status as an "incentive stock option" under
the Code (if such InterCAP Option had been an "incentive stock option") and
vesting schedules, which in the case of the ISO's provides for full vesting at
the Effective Date. To avoid fractional shares, the number of shares of
Intergraph Common Stock subject to an Assumed Option will be rounded up to the
nearest whole share and the exercise price will be rounded up to the nearest
cent. Prior to the Effective Date, Intergraph intends to file Registration
Statements on Form S-8 with the SEC with respect to the issuance of shares of
Intergraph Common Stock upon exercise of the Assumed Options.

     At the Effective Date, it is expected that 1,326,624 InterCAP Options will
be outstanding, of which 935,062 are ISO's and 391,562 are NQSO's.

agreed, jointly and severally, to indemnify Intergraph and Intergraph Sub and
their respective affiliates, successors and assigns (the "Indemnified Persons")
against certain losses arising from a breach of the representations and
warranties made by InterCAP in the Reorganization Agreement.  However, the
maximum liability of each InterCAP stockholder for such indemnification will not
(in the absence of fraud, willful misrepresentation, willful omission of a
material fact, or violation of the applicable securities laws) exceed such
stockholder's pro rata share of the Escrow Shares.  See "The Merger and Related

Termination

     The Reorganization Agreement provides that it may be terminated at any time

          (i) Mutual written consent duly authorized by the Boards of Directors
of Intergraph and InterCAP;

                                      -57-
<PAGE>

     
          (ii)  Intergraph, if any of Intergraph's Closing Conditions are not
satisfied or waived in writing by Intergraph by January 15, 1995;      
    
          (iii) InterCAP, if any of InterCAP's Closing Conditions are not
satisfied or waived in writing by InterCAP by January 15, 1995;      
    
          (iv)  Intergraph or InterCAP, if the Effective Date shall not have
occurred on or before January 15, 1995, or such later date agreed to in writing
by Intergraph and InterCAP;      

          (v)   Intergraph or InterCAP, if any court of competent jurisdiction
in the United States or other United States (federal or state) governmental body
shall have issued an order, decree or ruling or taken any other action
restraining, enjoining or otherwise prohibiting the Merger and such order,
decree, ruling or other action shall have been final and nonappealable; or

          (vi)  InterCAP, if the InterCAP Board of Directors determines to
pursue or accept a bona fide proposal or offer from a third party concerning any
merger, sale of assets, sale of additional securities or any similar transaction
and the Board of Directors has determined that the proposal or offer is more
favorable to InterCAP and its stockholders than the Merger and that it must
accept such proposal or offer in exercise of its fiduciary duties (any such
offer or proposal is referred to as a "Superior Offer," and termination in
respect of any Superior Offer is referred to as a "Superior Offer Termination").
See "The Reorganization Agreement--Certain Covenants" and "--Conditions to the
Merger."


Amendment

     The Reorganization Agreement may be amended in writing by InterCAP and
Intergraph at any time before or after approval of InterCAP's stockholders of
the Reorganization Agreement and the Merger, except that, after such stockholder
approval, no amendment may be made which reduces the total consideration paid by
Intergraph to the InterCAP stockholders or which materially and adversely
affects the rights of InterCAP's stockholders without the approval of such
stockholders.


Merger Expenses and Fees

     The Reorganization Agreement provides that, except under certain
circumstances, each of InterCAP and Intergraph will pay its own expenses
incurred in preparing for, entering into and carrying out the transactions
contemplated by the Reorganization Agreement.  Under certain circumstances,
however, if (i) neither Intergraph nor Intergraph Sub is then in material breach
of the Reorganization Agreement, and (ii) if the Reorganization Agreement is
terminated by Intergraph following any intentional breach by InterCAP of its
covenants contained in Article IV of the Reorganization Agreement or any
intentional or reckless material misstatement or omission

                                      -58-
<PAGE>
 
by InterCAP contained in the representations in Article III of the 
Reorganization Agreement, then in any such case, InterCAP must reimburse 
Intergraph for all reasonable, actual documented out-of-pocket fees or expenses 
(including but not limited to reasonable fees and expenses of counsel, 
accounting fees, travel expenses, registration or filing fees and the like) 
actually incurred in good faith by Intergraph or on its behalf in connection 
with the proposed Merger or the negotiation, structuring, evaluation or 
consummation of the transactions contemplated by the Reorganization Agreement 
(collectively, the "Designated Expenses").  Any such reimbursement must be made 
not later than three business days after the submission by Intergraph of a 
statement therefor.


Termination Fee

     The Reorganization Agreement also provides for the payment to Intergraph of
a termination fee in the event the Reorganization Agreement is terminated under
certain circumstances. According to the Reorganization Agreement, so long as
neither Intergraph nor Intergraph Sub is then in material breach of the
Reorganization Agreement and Intergraph and Intergraph Sub have satisfied the
conditions to InterCAP's obligations to consummate the Merger (to the extent
satisfaction or performance of such conditions is in the exclusive control of
Intergraph), if the Reorganization Agreement is terminated (i) by InterCAP
pursuant to a Superior Offer Termination, (ii) by Intergraph as a result of the
withdrawal or modification by the InterCAP Board of Directors of its
recommendation to the InterCAP stockholders with respect to the Merger (but only
if such withdrawal arises out of, relates to or follows any inquiry, contact or
proposal to InterCAP from a third party concerning any Superior Offer or other
proposed merger, sale of assets, sale of additional securities or similar
transaction), or (iii) by either party if any Superior Offer is approved by the
requisite vote of the holders of InterCAP Stock within 180 days of such
termination if such Superior Offer or the reasonable possibility of such
Superior Offer was known to InterCAP or its directors at the time the
Reorganization Agreement was terminated, then, in any such case, InterCAP shall
pay to Intergraph, at Intergraph's election, the amount hereafter specified (the
"Termination Fee"). If applicable, the Termination Fee will be equal to the
greatest of (i) the Designated Expenses plus an amount equal to the fully
allocated, reasonable documented cost of time (consisting of salary and
benefits) actually expended by Intergraph officers and employees in
investigating, negotiating, and taking steps necessary to consummate, the
transactions contemplated by the Reorganization Agreement (but in no event to
exceed $300,000 in the aggregate), (ii) $200,000 in cash, or (iii) 10% of the
excess over $7,500,000 of the total consideration (whether in the form of cash,
securities or other property, or an assumption of options or warrants) to be
paid to InterCAP or its security holders in connection with the Superior Offer.
The Reorganization Agreement requires that the applicable Termination Fee be
paid to Intergraph within ten days of termination unless the amount specified in
clause (iii) is selected by Intergraph, in which case such amount shall be
payable upon consummation of the transactions contemplated by the Superior
Offer.

THE BOARD OF DIRECTORS OF INTERCAP UNANIMOUSLY RECOMMENDS A VOTE FOR ADOPTION
AND APPROVAL OF THE REORGANIZATION AGREEMENT AND THE MERGER.

           PROPOSAL TO AMEND INTERCAP'S CERTIFICATE OF INCORPORATION


General

     The Board of Directors of InterCAP has adopted resolutions recommending,
and at the Meeting InterCAP stockholders will be asked to consider and act upon,
a proposed amendment to Article Fourth, Section I A, paragraph 4(a) of
InterCAP's Certificate that would extend the date from October 1, 1994 to
January 15, 1995, after which the liquidation preference of the InterCAP Series
A Preferred Stock would be increased from $1.475 per share to $1.475 per share
plus one-half of all accrued but unpaid dividends (which accrued at $1.475
annually) thereon.  The form of the Charter Amendment is attached as Appendix B
hereto.


Background

     Under the terms of the InterCAP Certificate, the original liquidation
preference of the InterCAP Series A Preferred Stock was fixed at $1.475 per
share, plus an amount equal to all accrued but unpaid dividends (at a rate of
10% per year) thereon from the original issue date (in 1988 or 1989) to the
effective date of the liquidation.  In addition, the InterCAP Certificate
provides that a consolidation or merger of InterCAP or a sale of all or
substantially all the assets of InterCAP is to be regarded as a liquidation of
InterCAP.  Moreover, in the case of a consolidation, merger or asset sale, each
holder of InterCAP Series A Preferred Stock is provided the option to elect to
receive in the transaction either the liquidation preference for the InterCAP
Series A Preferred Stock or to have the conversion privileges of the InterCAP
Series A Preferred Stock be appropriately adjusted such that after the
transaction, the InterCAP Series A Preferred Stock would be convertible into the
number of shares of stock or other securities or property of InterCAP or the
successor corporation to which a holder of that number of shares of InterCAP
Common Stock issuable upon conversion of the InterCAP Series A Preferred Stock
would have been entitled in the transaction.

     As discussed under "The Merger and Related Transactions--Background of the
Merger," the Board of Directors of InterCAP began actively considering a
strategic transaction involving InterCAP, including the possible sale of
InterCAP, in 1993.  Management believed that if InterCAP were then sold or
participated in a strategic combination with one or more other companies, all or
substantially all the proceeds would be distributed to the holders of InterCAP
Preferred Stock in respect of their liquidation preferences and, absent
adjustment to such liquidation preferences, the amount of proceeds available for
distribution to holders of InterCAP Common Stock, including employees who held
options to acquire shares of InterCAP Common Stock, would be nominal at best.
In recognition of the importance of incentivizing InterCAP's employees to
continue to build its business and to identify, negotiate and consummate a
strategic transaction, in May 1993, the Board of Directors of InterCAP proposed,
and thereafter InterCAP's stockholders (including all holders of InterCAP Series
A Preferred Stock) approved, an 

                                      -60-
<PAGE>
 
amendment to InterCAP's Certificate that reduced the liquidation preference of
the InterCAP Series A Preferred Stock from $1.475 per share plus all accrued but
unpaid dividends thereon to $1.475 per share plus (if the effective date of the
liquidation was after October 1, 1994) an amount equal to one-half of all
accrued but unpaid dividends thereon. The primary purpose of this amendment was
to provide incentive to InterCAP's management to consummate a strategic
transaction or sale of InterCAP by October 1, 1994.
    
     When active discussions between InterCAP and Intergraph commenced in August
1994, it became apparent that it would be difficult to consummate a merger
transaction by October 1, 1994.  Accordingly, InterCAP management personnel
asked the holders of InterCAP Series A Preferred Stock if they would be willing
to postpone the increase in the Series A Liquidation Preference to a date after
October 1, 1994 provided that InterCAP could execute a definitive agreement with
Intergraph by no later than September 30, 1994.  Such holders agreed on the
condition that the Merger be consummated no later than January 15, 1995. By 
virtue of the Reorganization Agreement Amendment, such holders have also agreed 
to postpone their rights in connection with the InterCAP Redemption Obligations 
until January 16, 1995 to permit consummation of the Merger no later than 
January 15, 1995.      

     Pursuant to the Preferred Stock Agreement, the holders of InterCAP
Preferred Stock who are parties thereto have agreed to vote all shares of
InterCAP Stock they own in favor of the Charter Amendment.  Such stockholders
have not, however, agreed to vote in favor of approval of the Reorganization
Agreement and the Merger, and they remain free to vote against, or not vote at
all with respect to, such matters.  See "Stockholder Approval of Reorganization
Agreement, the Merger and the Charter Amendment."


Effect of the Charter Amendment
    
     If the Charter Amendment is approved and adopted, the effect will be to fix
the liquidation preference of the InterCAP Series A Preferred Stock at $1.475
per share until January 15, 1995.  Accordingly, if the Merger is approved and
consummated prior to that date, the holders of InterCAP Series A Preferred Stock
will receive shares of Intergraph Common Stock with a value of $1.475 for each
share of InterCAP Series A Preferred Stock they own.  From a financial
viewpoint, the Charter Amendment benefits the holders of InterCAP Series B
Preferred Stock, InterCAP Series C Preferred Stock and InterCAP Common Stock by
increasing the amount of the Intergraph Common Stock they will receive in the
Merger by approximately 8%, or $.07 per InterCAP share.      


               STOCKHOLDER APPROVAL OF REORGANIZATION AGREEMENT,
                      THE MERGER AND THE CHARTER AMENDMENT


Stockholder Vote

     The Reorganization Agreement and the transactions contemplated thereby must
be approved by the stockholders of InterCAP.  The Charter Amendment must also be
approved by 

                                      -61-
<PAGE>
 
the stockholders of InterCAP prior to the consummation of the Merger. See
"Proposal to Amend InterCAP's Certificate of Incorporation." Accordingly, both
the Charter Amendment and the Reorganization Agreement must be accepted and
approved by the stockholders of InterCAP.


Stockholder Meeting

    
     A special meeting of the InterCAP stockholders will be held on January 11,
1995 at 8:00 a.m. at InterCAP's offices at 116 Defense Highway, Suite 400,
Annapolis, Maryland 21401, for purposes of (i) consideration of the approval and
adoption of the Charter Amendment; and (ii) consideration of the approval of the
Reorganization Agreement (the "Meeting").      


Record Date and Shares Entitled to Vote

     The Board of Directors of InterCAP has fixed the close of business on
December 1, 1994 as the Record Date for the determination of stockholders
entitled to notice of and to vote at the Meeting.  Accordingly, only InterCAP
stockholders as of the close of business on the Record Date will be entitled to
vote at the Meeting.  On the Record Date, there were the following number of
shares of capital stock of InterCAP outstanding and entitled to vote: (i)
2,911,478 shares of InterCAP Common Stock and (ii) 3,597,155 shares of InterCAP
Preferred Stock, of which (A) 927,326 shares are designated InterCAP Series A
Preferred Stock; (B) 1,716,387 shares are designated as InterCAP Series B
Preferred Stock; and (C) 953,442 shares are designated as InterCAP Series C
Preferred Stock.  Each share of InterCAP Common Stock and InterCAP Preferred
Stock is entitled to one vote per share, except that the InterCAP Series A
Preferred Stock is entitled to 1.3329 votes per InterCAP Series A Preferred
share.


Proxies; Quorum

     Shares of InterCAP Common Stock and InterCAP Preferred Stock represented at
the Meeting by properly executed proxies will, unless such proxies previously
have been revoked, be voted in accordance with the instructions indicated in
such proxies.  If no instructions are so indicated, such shares will be voted by
InterCAP in favor of the adoption and approval of the Charter Amendment and
adoption and approval of the Reorganization Agreement and the transactions
contemplated thereby.  See "Proxy Solicitation."

     Any InterCAP stockholder giving a proxy in the form accompanying this
Prospectus/Proxy Statement has the power to revoke the proxy before its use.  A
proxy can be revoked (i) by an instrument of revocation delivered before the
Meeting to the Secretary of InterCAP, (ii) by a duly executed proxy bearing a
later date or time than the date or time of the proxy being revoked, or (iii) by
voting in person at the Meeting.  Attendance at the Meeting will not by itself
revoke a proxy.

                                      -62-
<PAGE>
 
     The presence either in person or by properly executed proxy of the holders
of a majority of the outstanding shares of each class of InterCAP Stock entitled
to vote on the Charter Amendment and the Reorganization Agreement is necessary
to constitute a quorum at the Meeting.


Vote Required for Charter Amendment

     Under the InterCAP Certificate and the Delaware Act, approval and adoption
of the Charter Amendment requires the affirmative vote of the holders of (i) a
majority of the outstanding shares of InterCAP Common Stock and InterCAP
Preferred Stock, voting as a single class; (ii) a majority of the outstanding
shares of InterCAP Series A Preferred Stock, voting separately; (iii) a majority
of the outstanding shares of InterCAP Series A Preferred Stock and InterCAP
Series B Preferred Stock; voting as a single class; and (iv) a majority of the
outstanding InterCAP Series C Preferred Stock, voting separately. The failure of
a holder of record of InterCAP Stock to vote in person or by proxy at the
Meeting will have the same effect as a vote against the Charter Amendment.
Substantially all the holders of the InterCAP Preferred Stock have agreed to
vote all of their InterCAP Stock in favor of the Charter Amendment, and such
holders have sufficient voting power to satisfy each of clauses (i)-(iv) above.
At the close of business on the Record Date, such persons held approximately
14.03% of the outstanding InterCAP Common Stock, 100% of the outstanding
InterCAP Series A Preferred Stock, approximately 98.85% of the outstanding
InterCAP Series B Preferred Stock, 100% of the outstanding InterCAP Series C
Preferred Stock, and approximately 63.00% of the combined voting power of the
InterCAP Common Stock and InterCAP Preferred Stock, taken together. Accordingly,
the Charter Amendment will be approved and adopted by InterCAP's stockholders at
the Meeting, even if no other stockholders of InterCAP vote in favor of the
Charter Amendment.


Vote Required for Reorganization Agreement and Merger

     Under the InterCAP Certificate and the Delaware Act, approval and adoption
of the Reorganization Agreement and Merger requires the affirmative vote of (i)
at least 66.67% of the outstanding shares of InterCAP Common Stock and the
InterCAP Preferred Stock, voting as a single class, and (ii) a majority of the
outstanding shares of InterCAP Series A Preferred Stock and InterCAP Series B
Preferred Stock, voting as a single class.  The failure of a holder of record of
InterCAP Stock to vote in person or by proxy at the Meeting will have the same
effect as a vote against the Reorganization Agreement.  The directors of
InterCAP have indicated that they presently intend to vote all shares of
InterCAP Stock over which they have voting power in favor of the Merger.
Accordingly, if the directors vote in accordance with this indication, the
Merger will be approved by the stockholders, even if no other stockholder of
InterCAP votes in favor of the Merger.  InterCAP stockholders should note that
neither the directors of InterCAP nor any other InterCAP stockholder is under
any contractual obligation to vote his or its shares of InterCAP stock in favor
of the Merger.  Accordingly, although the 

                                      -63-
<PAGE>
 
directors of InterCAP have indicated their current intention is to vote in favor
of the Merger, such indication is not binding on them and they each retain the
right to vote against, or not vote at all with respect to, the Merger.


Beneficial Security Ownership of Certain Persons

     The directors and executive officers of InterCAP beneficially owned, or
exercised voting control over, as of September 30, 1994, 1,145,070 shares
(representing 39.33% of the total outstanding shares) of InterCAP Common Stock,
927,326 shares (representing 100.00% of the total outstanding shares) of
InterCAP Series A Preferred Stock, which in turn represents 1,236,033 votes,
1,696,657 shares (representing 98.85% of the total outstanding shares) of
InterCAP Series B Preferred Stock, and 953,442 shares (representing 100.00% of
the total outstanding shares) of InterCAP Series C Preferred Stock. Insofar as
the holders of InterCAP Common Stock and InterCAP Preferred Stock are required
to vote as a single class, such directors and executive officers beneficially
own or control 73.80% of the combined classes; insofar as the holders of
InterCAP Series A Preferred Stock and InterCAP Series B Preferred Stock are
required to vote as a single class, such directors and executive officers
beneficially own or control 99.33% of the combined classes. See "Security
Ownership of Certain Beneficial Owners and Management of InterCAP."


Dissenters' Rights

     Holders of InterCAP Stock have the right to demand appraisal of, and obtain
payment for, the "fair value" of their shares by following the procedures
prescribed in Section 262 of the Delaware Act, a copy of which is attached
hereto as Appendix C.  A holder of shares of InterCAP Stock who or which wishes
to exercise his or its appraisal rights must not vote in favor of the approval
and adoption of the Reorganization Agreement and the Merger.  Failure to take
any of the steps required under Section 262 on a timely basis may result in the
loss of appraisal rights.  See "The Merger And Related Transactions--Dissenters'
Rights" in this Prospectus/Proxy Statement.

are incorporated herein by reference. See "Available Information" and
"Incorporation of Certain Documents by Reference."     

    
Recent Developments      
         
     In its Quarterly Report on Form 10-Q for the quarter ended June 30, 1994,
Intergraph reported the award by the United States Navy on July 13, 1994 of a
multi-year, indefinite delivery, indefinite quantity contract (the Naval Air
Systems Command and Space and Naval Warfare Command or "NAVAIR and SPAWAR"
contract) to provide computer aided design, manufacturing and engineering
systems and services for electronics and mechanical applications. Intergraph
further reported that the award of this contract (which has an estimated value
of $398 million) had been formally protested by one of the losing bidders.
Subsequent to the filing of its September 30, 1994 Quarterly Report on Form 
10-Q, the formal protest was rejected by the General Services Administration's
Board of Contract Appeals. As a result, the Navy's award of this contract to
Intergraph was upheld.      
         
     In its annual report to shareholders for the year ended December 31, 1993,
Intergraph reported the August, 1993 signing of an agreement with Sun
Microsystems Computer Corporation ("Sun") to co-develop the next generation Sun
SPARC high-end microprocessor, develop a SPARC-based, high quality desktop
computer system, and port the Windows NT operating system to that computer
system.  In addition, under the terms of the agreement Sun hired seventy-seven
employees of Intergraph's Advanced Processor Division ("APD") on January 1, 1994
and has the obligation to offer employment to the remaining twenty APD employees
on January 1, 1995.  The commercial result of the agreement for Intergraph was
the right to purchase from Sun the co-developed microprocessor and the right to
sell the SPARC-based computer system operating under the Windows NT operating
system with Intergraph's technical software applications, all in the second half
of 1995.       
         
     Sun and Intergraph agreed to revise certain terms of the agreement in mid-
1994.  Thereafter, Sun terminated the agreement with Intergraph effective
October 7, 1994.  As a result, the next generation Sun SPARC microprocessor will
not be co-developed, Intergraph will not develop the SPARC-based desktop
computer system, Intergraph will not port the Windows NT operating system to
that computer system, and Intergraph will not have the right to sell the
computer system.  However, Intergraph retains a right for approximately three
years to purchase Sun developed microprocessors.  APD employees hired by Sun on
January 1, 1994 remain the employees of Sun and Sun still has the obligation to
hire remaining APD employees effective January 1, 1995.  Intergraph has ceased
design of its own microprocessor, and will cease volume production of its
microprocessor in 1995.  Termination of the contract by Sun did not of itself 
     

                                      -65-
<PAGE>
 
    
produce any adverse financial effects to Intergraph, and Intergraph does not
expect that such termination will result in adverse effects on its future
operations.      
                  
     In late November 1994 it was disclosed that a rare problem may exist with
initial versions of Intel's Pentium microprocessor, which is used in many of
Intergraph's workstations.  The problem relates to an unlikely sequence of
operations that can produce a round-off error when dividing certain numbers and
carrying the answer to several decimal places.  Intel has said the error is 
likely to occur only once in every nine billion random division operations.
Intergraph has shipped several thousand Pentium processor-based workstations and
servers to date.      
         
     Intergraph has not experienced any reports of this problem from a customer
site, and has not experienced the problem during internal development.
Accordingly, Intergraph at present has no reason to believe that current or
future customers are likely to encounter the problem, and it has experienced no
adverse impact on sales thus far. Intel has said it will warrant the processor
on this issue, and Intergraph's business arrangements with Intel provide
warranty coverage of the Pentium microprocessor by Intel. For these reasons,
Intergraph at present does not believe this problem is likely to adversely
affect its results of operations or financial position.      


                      MANAGEMENT'S DISCUSSION AND ANALYSIS
          OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS OF INTERCAP


     The following discussion should be read in conjunction with the InterCAP
consolidated financial statements and notes thereto appearing elsewhere in this
Prospectus/Proxy Statement.


Overview

     InterCAP designs and produces complex computer software systems that assist
in creating, editing, converting and presenting technical illustrations used by
large manufacturing firms.  InterCAP's revenues are derived through the initial
license of its products and from annual license renewals and related customer
support services.

     InterCAP is a small company vendor of "big ticket" software products, with
the majority of its new license revenues being made up of individual orders in
excess of $75,000.  InterCAP's customers are generally Fortune 500 corporations
or are large government agencies.  Consequently, InterCAP has very little
ability to influence the timing of its customers' buying decisions or orders.
As a result, a single order may make the difference between InterCAP reporting
profits and reporting losses.  Accordingly, InterCAP has traditionally
experienced significant volatility in its quarterly and annual sales levels and
profitability due to fluctuations in unit sales of the Illustrator products.
Pricing has played no role in this volatility, as InterCAP has not modified its
pricing or discount policies since 1991.

                                      -66-
<PAGE>
 
     Because of the newness of InterCAP's MetaLink products, essentially all of
the company's revenues have been and continue to be the result of initial and
annual license fees for the Illustrator product family in general, and the
Illustrator 2 product in particular.  The following table breaks down the
sources of InterCAP's revenue for the periods indicated by product family (with
dollars expressed in thousands).

Results of Operations - Years Ended June 30, 1992, 1993 and 1994

     Summary

     Net income for the year ended June 30, 1994 was $781,000 compared to a net
loss of $515,000 during the year ended June 30, 1993. The year ended June 30,
1994 increase in net income was due to a 19% increase in revenues coupled with a
16% decrease in operating expenses.

     The net loss for the year ended June 30, 1993 was $515,000 compared to net
income of $207,000 during the year ended June 30, 1992. The net loss incurred
during the year ended June 30, 1993 was due to an 18% decline in revenues.

     Net income was $207,000 during the year ended June 30, 1992, down 81.4%
from the same period the preceding year. The relative decrease was predominantly
due to extraordinary nonoperating gains recognized in fiscal 1991.

     During the years ended June 30, 1994 and 1992, net operating loss
carryforwards were utilized to reduce income taxes otherwise payable. The
benefit of this reduction is shown as an extraordinary item in the accompanying
consolidated statements of operations for the year ended June 30, 1992. InterCAP
had net operating loss carryforwards for income tax purposes of 

                                      -67-
<PAGE>
 
approximately $ 1,478,000, $2,500,000, and $2,300,000 at June 30, 1994, June 30,
1993, and June 30, 1992, respectively, expiring in years 2002 through 2006.

     Revenues

     InterCAP sells (licenses) its products directly through its own sales force
located in the U.S. and Germany, and through original equipment manufacturers
and distributors. Customer support revenues, which include recurring annual
license renewals and other related services, are conducted through the company's
U.S. and Swiss operations. Revenues are classified as U.S. Direct, Foreign
Direct, Original Equipment Manufacturers and Distributors, U.S. Customer Support
and Foreign Customer Support.

     Consolidated sales revenues increased by $711,000, or 19%, to $4,490,000
for the year ended June 30, 1994, as compared to the year ended June 30, 1993.
The year ended June 30, 1994 increase is primarily attributable to increases in
U.S. direct sales, which increased 78%, or $846,000, to $1,931,000. Of this
amount, $483,000 was made up of orders for the new MetaLink products, and the
balance consisted of license fees for InterCAP's Illustrator 2 and derivative
products. InterCAP believes fiscal 1995 U.S. sales will be comparable to 1994
results.

     The increase in fiscal 1994 U.S. Direct Sales was partially offset by a
35%, or $78,000, decrease in Foreign Direct Sales from InterCAP's German
operations, which are conducted through a wholly owned subsidiary of InterCAP.
InterCAP attributes the decline to general conditions in the sluggish German
economy. InterCAP does not expect German revenues to improve significantly until
the German economy improves.

     Original Equipment Manufacturer and Distributor sales decreased 25%, or
$182,000 for the year ended June 30, 1994 to $549,000. InterCAP terminated its
relationship with its largest European distributor and replaced it with two new
distributors located in Europe. Reductions in sales were due to weakness in the
overall European economy, and from disruption due to new distributors coming on
board mid-year and year-end. InterCAP anticipates modest growth in distributor
sales in fiscal 1995 as the new distributors become more productive.

     U.S. Customer Support revenues increased 8%, or $65,000, to $869,000 for
the year ended June 30, 1994, due to growth in the installed base.

     Foreign Customer Support revenues from InterCAP's wholly owned Swiss
subsidiary, which services customers located in England, Germany, Switzerland,
France and Italy, increased 6%, or $53,000, to $937,000 for the year ended June
30, 1994, due to growth in the installed base. InterCAP expects customer support
revenues to increase modestly in fiscal 1995.

     For the year ended June 30, 1993, total consolidated sales revenues
declined 18%, or $818,000, to $3,779,000, as compared to $4,597,000 for the year
ended June 30, 1992. Decreases were experienced in every revenue classification
and geographic location except for Foreign Customer Support, which enjoyed an
increase of 51%, or $299,000, to $884,000 for the 

                                      -68-
<PAGE>
 
year ended June 30, 1993. U.S. Direct Sales, Foreign Direct Sales, Distributor
sales and U.S. Customer Support were down 13%, 61%, 16%, and 13%, respectively,
from the comparable prior year period. The downturns in both U.S. and European
economies were the primary cause for the decline as major corporations halted or
delayed capital expenditures and focused on downsizing.

     The Foreign Customer Support revenue increase during the year ended June
30, 1993 was due to growth in the number of customers purchasing annual license
renewals.

     Consolidated sales revenues increased by $144,000, or 3.2% during the year
ended June 30, 1992 to $4,597,000, as compared to $4,452,000 during the year
ended June 30, 1991. U.S. Direct Sales, Original Equipment Manufacturers and
Distributors and Foreign Customer Support were up 24%, 43% and 42%,
respectively, from the comparable prior year period. These increases were offset
by decreases in Foreign Direct Sales and U.S. Customer Support revenues of 44%
and 26%, respectively.

     Selling, General and Administrative Expenses

     For the year ended June 30, 1994, selling, general and administrative
expenses decreased by 16%, or $504,000, from fiscal 1993 due to a 12% reduction
in headcount. All reductions were in the sales area and resulted from a decision
to focus sales efforts on a fewer number of larger opportunities. This reduction
resulted in decreased direct labor expenses of 16%, or $337,000, and led to
related reductions in overhead expenses. InterCAP plans to continue to monitor
closely all expenses and does not anticipate a significant increase in expenses
for fiscal year 1995.

     For the year ended June 30, 1993, selling, general and administrative
expenses decreased 5%, or $152,000 from the year ended June 30, 1992. Increases
in advertising expense, professional fees and direct labor expenses of $49,000,
$51,000 and $50,000, respectively, were offset against reductions in equipment
rental expenses and bad debt expenses of $80,000 and $44,000, respectively.

     Selling, general and administrative expenses increased 5%, or $154,000
during the year ended June 30, 1992 due to increases of $314,000 in direct labor
expenses, $49,000 in taxes and licenses and $44,000 in bad debt expenses, offset
by reductions of $152,000 in professional fees.

     Gross Margin

     Gross margin for the year ended June 30, 1994, was 78.2% versus 69.8% and
73.1% for the years ended June 30, 1993, and June 30, 1992, respectively. The
8.4 point increase in gross margin from the year ended June 30, 1993 to the year
ended June 30, 1994 was the result of a shift downwards in the ratio of sales
through distributors to total company sales, because sales through distributors
earn a lower margin than direct sales to end users.

                                      -69-
<PAGE>
 
     Gross margins at the year ended June 30, 1993, declined 3.3 points from the
year ended June 30, 1992, due to a decline in sales volume.

     Gross margins for the year ended June 30, 1992, decreased 9.0 points from
the same period of the preceding year, primarily due to distributor commissions
included in cost of products sold during the year ended June 30, 1992. During
the year ended June 30, 1991, Distributor Commissions were offset against
Original Equipment Manufacturer and Distributor revenues resulting in a higher
reported margin.

     Taxes

     Taxes have historically not been a significant item in InterCAP reporting
due to the utilization of net operating loss carryforwards accumulated prior to
1991. At June 30, 1994, InterCAP's net operating loss carryforward balance was
$1,478,000, versus $2,500,000 at June 30, 1993 and $2,300,000 at June 30, 1992.

     Liquidity and Capital Resources

     At June 30, 1994, InterCAP had approximately $132,000 in cash and cash
equivalents, as compared to $260,000 at June 30, 1993. InterCAP's net working
capital was $527,000 at June 30, 1994, as compared to a $39,000 working capital
deficit at June 30, 1993. The increase was primarily attributable to increased
cash flow from increased sales activity and profitable operations. Under the
terms of the InterCAP Preferred Stock, beginning in January 1995, InterCAP may
be required to redeem in three annual payments the outstanding InterCAP
Preferred Stock at its original issue price, plus dividends accrued at a 10%
annual rate from the original date of purchase (the "Redemption Amounts").
Because maximum redemption payments are limited to InterCAP's preceding 12
months net income, the precise Redemption Amounts, if any, are currently
unknown.


Results of Operations - Three Months Ended September 30, 1993 and 1994

     Summary

     InterCAP's net income for the quarter ended September 30, 1994, was
$194,000, compared to a loss of $224,000 during the quarter ended September 30,
1993. InterCAP's increase in net income for the quarter ended September 30, 1994
was due to a 107% increase in revenues, while operating expenses increased 14%.

     Revenues

     InterCAP sells (licenses) its products directly through its own sales force
located in the U.S. and Germany, and through Original Equipment Manufacturers
and Distributors. Customer support revenues which include recurring annual
license renewals and other related services are 

                                      -70-
<PAGE>
 
conducted through the company's U.S. and Swiss operations. Revenues are
classified as U.S. Direct, Foreign Direct, Original Equipment Manufacturers and
Distributors, U.S. Customer Support and Foreign Customer Support.

     During the quarter ended September 30, 1994, U.S. Direct Sales, Foreign
Direct Sales and Foreign Customer Support were up 584% or $492,000, 304% or
$35,000, and 74% or $103,000, respectively, from the comparably weak prior year
period. U.S. Direct Sales included a single sale for $519,000 to the U.S.
Department of Defense, which represented the first order InterCAP has received
under the JCALS contract originally awarded in 1992. Revenues for the quarter
ended September 30, 1994 were $1,110,007 compared with $536,145 for the
comparable quarter of the prior year. Original Equipment Manufacturer and
Distributor Sales and U.S. Customer Support Revenue declined 13% or $24,000 and
14% or $14,000, respectively, during the quarter ended September 30, 1994 versus
the quarter ended September 30, 1993.

     Gross Margin

     Gross margin for the quarter ended September 30, 1994 was 77.7% versus
63.0% for the quarter ended September 30, 1993 due to strong revenue growth on
modest expense increases.

     Selling, General and Administrative Expenses

     During the quarter ending September 30, 1994, selling, general and
administrative expenses increased 14%, or $75,000, from the quarter ended
September 30, 1993. The increase is partially due to increases in professional
fees, which were up 775% or $30,000, due to recognition of audit and tax
preparation fees in the first quarter of fiscal year 1995 versus recognition of
similar charges in the second and third quarter of fiscal year 1994.

     Taxes and licenses were up $25,000 or 102% during the quarter ending
September 30, 1994 as compared to the quarter ended September 30, 1993, due to a
favorable 1993 adjustment of $25,000 to reduce an overaccrual of value added tax
incurred by InterCAP's German subsidiary. Direct labor costs were up 4% or
$19,000 during the quarter ended September 30, 1994, as compared to the quarter
ended September 30, 1993.

     Taxes

     During the quarter, InterCAP utilized net operating loss carryforwards to
reduce its accrued tax expense to approximately 7% of net income, or $14,000.

     Liquidity and Capital Resources

     At September 30, 1994, InterCAP had approximately $14,000 in cash and cash
equivalents as compared to $132,000 at June 30, 1994. InterCAP's net working
capital was $717,000 at September 30, 1994, as compared to a $527,000 working
capital at June 30, 1994. The increase was primarily attributable to increased
cash flow from sales activity and profitable operations.

                                      -71-
<PAGE>
 
     InterCAP has a $400,000 revolving credit agreement. Availability is
restricted by the receivable balances.

     InterCAP believes that existing cash balances together with cash from
operations and cash available from its revolving line of credit agreement will
be adequate to meet operating cash requirements during the upcoming fiscal year
(exclusive of any Redemption Amounts required in connection with the InterCAP
Preferred Stock).


                             BUSINESS OF INTERCAP


Introduction

     InterCAP was incorporated in Delaware in 1987. The principal offices of
InterCAP are located at 116 Defense Highway, Suite 400, Annapolis, Maryland
21401, telephone (410) 224-2926. InterCAP has two wholly owned foreign sales and
customer support subsidiaries, InterCAP Graphics Systems, Gmbh, 
Paul-Ehrlich-Strasse 1, 69181 Leimen, Germany, and InterCAP Graphics Systems,
AG, Dorfzentrum, 8917 Oberlunkhofen, Switzerland.

     InterCAP designs and produces complex computer software systems that assist
in creating, editing, converting and presenting technical illustrations used
extensively by large manufacturing firms in documentation, maintenance,
manufacturing and assembly, and training. InterCAP's products allow illustrators
to include many different types of graphic source materials in their electronic
artwork and provide the capability to incorporate and blend existing CAD
graphics with scanned images derived from existing paper, film, electronic and
live video artwork to produce high-quality finished artwork on a wide variety of
text composition systems, laser printers, phototypesetters and plotters.

     InterCAP markets its software products directly and through independent
distributors, primarily to large multinational corporations. InterCAP has a
diversified domestic and international customer base. InterCAP's clients include
market leaders in aerospace, automotive, defense, farm and construction
equipment manufacturers, medical products, recreation, industrial equipment,
electronic systems, computer systems and consumer products. Domestic business
includes government programs with the Department of Defense "Commerce at Light
Speed" ("CALS") initiative. InterCAP sells its products through a direct sales
force of three sales persons (two domestic and one international), and seven
value-added resellers ("VARs"), which include international distributors and
original equipment manufacturers ("OEMs"). Pre-sales support is a joint effort
of InterCAP's salesmen and technical support engineers along with VARs,
distributors and OEMs in international installations. Customer support is
generally handled directly by InterCAP.

     InterCAP is now focusing on assisting clients in two strategic areas: (1)
cost reduction in the creation and management of quality illustrations and
technical drawings, and (2) efficiency 

                                      -72-
<PAGE>
 
improvement in the overall technical document publishing and distribution
process. While InterCAP is already a leading source of software for professional
technical illustrators, InterCAP is also pioneering the evolution of critical
industry standards in the CGM and CALS arenas.


Principal Products and Services

     From the perspective of the underlying technology, all of InterCAP's
products are directly derived from the lead product in each of two core software
source code sets. These are the Illustrator and MetaLink product families. The
individual products within a product family are comprised of essentially
identical internal technology, with a relatively small amount of effort devoted
to modifying the user interface. Such modifications allow InterCAP to disable or
highlight different functions, and hence offer a suite of internally identical
products with graduated levels of performance at different price points. By way
of example, a writer often needs a simple, low cost, easy-to-use graphics
package that is complementary to the complex and expensive systems used by a
professional illustrator. From a pricing and packaging standpoint, InterCAP
offers a product for each, but internally, both products are in fact the same-
high end system. The Illustrator 2 family includes Illustrator 2 ($27,000),
Mechanical Drafting Plus ($9,950), Quick-Edit ($2,500), RedLiner ($995) and 
X-Change ($4,950). The MetaLink family is comprised of MetaLink Author ($7,500)
and MetaLink RunTime ($995).

     The primary differences between the product suites relates to their
underlying data model, and their targeted hardware and operating system
platforms. The Illustrator architecture uses 1980's computer technology, was
designed specifically and exclusively to support UNIX operating system based
hardware, and uses InterCAP's proprietary graphics format as its internal data
model. The architecture is extremely feature rich, and is recognized in the
industry to be among the most powerful illustration tools on the market. The
products are fully mature from the perspective of reliability as a result of the
input of thousands of man years of production illustration into the development
process. While "state of the art" in today's market, InterCAP anticipates
changes to the market that are both a long-term threat and an intermediate-term
opportunity. Because of the long lead times in developing software, InterCAP
began developing its next generation MetaLink technology in 1993, even though it
expects the Illustrator family to continue to generate the majority of
InterCAP's revenues at least through 1995. Over the next two to three years, as
the MetaLink family of products begin to match the functionality of the
Illustrator products, InterCAP's plan is to migrate its installed customer base
to MetaLink based software tools.

     Although the MetaLink family of products currently lacks the richness and
robustness of the Illustrator products due to its newness, InterCAP believes
MetaLink products are responsive to the long-term direction of its markets for
three primary reasons. First, the sharing of technical information, including
graphics, is becoming increasingly important as vendors, customers and suppliers
continue to try to compress time-to-market and time-to-repair. The rapid sharing
of technical information remains a significant bottleneck in industry.
Historically, such information exchange was addressed through the use of filters
between proprietary systems. This business 

                                      -73-
<PAGE>
 
model is well supported by the Illustrator products, and is standard practice in
today's market. InterCAP believes that the elimination of the filtering process
will make possible a potentially significant improvement in the speed and
accuracy with which companies can share information. To eliminate filtering
requires the extensive native use of international standards rather than
proprietary formats. The internal data model in MetaLink is the Computer
Graphics Metafile (CGM), which is the International Standards Organization's
recommended open systems format for the exchange of illustrations. CGM has been
adopted as the preferred graphics format by the U.S. Department of Defense,
aerospace, telecommunications, and automobile industries, among others. InterCAP
has played a key role in the authorship of the CGM standard, and InterCAP
officers hold senior positions in the several of the related international
standards bodies. Second, MetaLink has been designed to support fully both UNIX
and PC based operating systems. InterCAP believes that the PC presents an
attractive target market for its products, and positions it to compete more
effectively against companies selling only UNIX based products.

     Finally, Illustrator represents nearly 1,000,000 lines of computer code
developed over a decade. The complexity and size of the system increases the
cost and time involved in enhancing or modifying the products. InterCAP
management believes that "starting from scratch" with respect to the development
of a next generation computer architecture will provide it long-term advantages
in the speed and quality from which future MetaLink based products can be
spawned from the new core architecture.

     InterCAP presently offers seven major software products, described below,
each of which currently run, on UNIX-based workstations. The software is
supplied in a bundle with a complete "suite" of input and output device drivers
and file format conversion programs. InterCAP is presently developing versions
of its existing products to run on personal computers ("PCs") utilizing 32-bit
Microsoft/TM/ operating systems and is planning additional products to expand
its 32-bit PC offerings, while maintaining its position in the UNIX market.

          Illustrator 2 automates the graphics authoring and creation segment of
the computer-aided publishing process. It allows professional technical
illustrators in the aerospace, defense, electronics, heavy equipment and other
manufacturing industries to manipulate graphic data by combining mixed media,
such as raster data (scanned images), video, and two dimensional and three
dimensional vector data (geometric entities). Illustrator 2 features an
intuitive user interface, data integration and manipulation capabilities, data
storage and retrieval abilities, and time-saving data creation and editing
features.

          Mechanical Drafting Plus was developed specifically for creating,
editing and maintaining high quality legacy mechanical engineering drawings.
Mechanical Drafting Plus features hybrid raster/vector databases, dimensioning
and tolerancing capability.

          Quick Edit, first made available in 1992, is a graphics editor that
permits technical authors and other casual users of industrial graphics quickly
and easily to "finish-up" or modify illustrations. With over 200 drawing and
editing commands at their disposal, technical writers, engineers, and
illustrators can use Quick Edit for raster, vector and photo editing, all under
a 

                                      -74-
<PAGE>
 
single user interface. Quick Edit is conveniently distributed across any local
area networks to enhance productivity while facilitating the sharing of
professional expertise.

          Red-Liner is an easy-to-use software package for electronically
viewing, marking up, and commenting on technical illustrations and engineering
drawings. It can be used on a stand alone basis or integrated with Illustrator
2. Released in 1993, Red-Liner can create industry-standard CGM vector graphics
markup files, protect the original art from changes during markup, and guide
revisions of the finalized graphics.

          X-Change is a graphical data conversion tool that provides direct
translation between a variety of industry-standard file formats. It is designed
to streamline the flow of graphic data between engineering, manufacturing and
publishing functions. In addition to InterCAP's proprietary formats, this
package can convert from a large variety of dissimilar software products and
peripheral devices, including all major U.S. government, international and
industrial standards. X-Change was first released in 1993.

          MetaLink Author, InterCAP's newest product, is targeted to
illustrators and "document engineers" responsible for assembling intelligent
graphics for use within intelligent electronic information presentation systems
known as Interactive Electronic Technical Manuals or "IETM's". MetaLink is the
first native implementation of the new CGM standard that supports animation,
integrated revision control, and graphical linking (i.e., the ability to "chick"
on an arbitrary portion of an electronic image, and receive related or more
detailed information, for example, to determine whether a highlighted part
represented in a computer displayed graphic is in stock, or to instruct the
computer to play a video sequence showing how to replace the identified part in
a real piece of equipment).

          MetaLink Runtime is the companion product to InterCAP's MetaLink
Author. MetaLink Runtime allows organizations to present CGM encoded electronic
technical illustrations in advanced IETM's and intelligent graphics
applications. The architecture is expected to be the base of all future InterCAP
graphics products.

     InterCAP also provides a variety of services ancillary to the design and
marketing of its products, including system installations, training and support.
These services are essential to maintaining an important part of InterCAP's
business renewal customers.


Product Pricing and Licensing

     InterCAP's sales practices are based on the concept popularized by IBM of a
relatively large "Initial License Fee" followed each year by smaller recurring
but non-optional annual use or annual license fees. The annual fee is not a
"maintenance" charge, because all that is conveyed to the customer is the right
to continue to use the software for another 12-month period. This pricing model
has the benefit of increasing the reliability and predictability of recurring
revenues, and allows InterCAP to forecast a significant portion of its revenues
more accurately. The 

                                      -75-
<PAGE>
 
Annual Renewal Fee is based on 21% of the list price for the Initial License Fee
of the relevant product. Both Initial License Fees and Annual Renewal Fees are
subject to published discounts based on the cumulative installed value of all
previous orders. Quantity discounts range up to 35% on Initial License Fees, and
40% for Annual Renewal Fees. Professional services such as training, consulting
or customer support beyond the telephone hotline represent incremental costs and
are charged separately. InterCAP charges a 25% premium for each of its licensing
options and services in the European and Japanese markets. InterCAP generally
does not discount from its published price book, except for large volume orders
of its lower priced products when the customer takes on added responsibility,
such as reproduction and distribution within the account.


Competition

     At the "high end" of the illustration market, InterCAP competes with 
Auto-trol Technology Corporation. In this segment, InterCAP competes on the
quality of its software products and technical support, and on its tight
adherence to industry standards, rather than on price. InterCAP's products also
sometimes compete with less sophisticated illustrator products, such as those
offered by Corel and Autodesk, Inc., when price is more heavily weighted than
performance.

     In the graphics data conversion tool arena, InterCAP competes against low
price, often PC-based, software tools. InterCAP competes in this segment through
the high quality of its adherence to the CGM standard.

     The MetaLink family of products currently has no direct competition. By
virtue of InterCAP's leading role in developing the new international standards
on which these products are based, InterCAP was the first, and is still the
only, company to market this new technology.


Backlog

     InterCap's annual license renewals from its installed base total
approximately $2,000,000. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations of InterCAP." Customer renewal rates have
historically averaged around 95% annually. InterCAP has a $5,800,000 "Indefinite
Delivery Indefinite Quantity" contract to supply software to the Department of
Defense over an eight-year period, although there can be no assurance that any
amounts will be received under this contract in future years. The JCALS program
is a Department of Defense initiative designed to automate and streamline the
creation and distribution of technical information. The program, taken as a
whole, has a nominal value of $744 million. Computer Science Corporation is the
Prime Contractor. InterCAP received its IDIQ subcontract in 1992 to provide
versions of its Illustrator products as a component in the overall system. An
IDIQ contract from the U.S. Government is not a "contract" in the commercial
sense. Rather, it is a sales vehicle under which line buying entities within the
government, such as an individual Air Force base, can procure products. The 
contract award 

                                      -76-
<PAGE>
 
carries with it the implicit endorsement of the government as "best value." In
addition, as part of a IDIQ award, master pricing agreements are negotiated that
effectively eliminate the red-tape normally involved in a government
procurement. Although an IDIQ contract makes procurement of competing products
more difficult, it carries with it no direct funding, and actual purchasing
decisions are left to the discretion of the line buying entities. The government
can cancel the master contract at any time with no reason, and individual buying
entities are under no obligation to procure through the contract. The nominal
$5.8 million contract awarded to InterCAP represents the government's estimate,
as well as a maximum, of purchases it believes buying entities may procure
during the 10 year life of the contract. During the first two years after the
contract award, InterCAP received no revenues from the contract. In September
1994, InterCAP received the first order under the contract for $519,000 for
Illustrator products for delivery to various Army, Navy and Air Force bases.
While InterCAP expects additional orders will be obtained in the future, it is
not currently aware of any planned procurements, and has no additional revenues
from the contract built into its internal operating plans.


Strategic Partnerships

     InterCAP has a number of strategic partnerships in place that extend and
enhance the sales, marketing, support and technical resources of the company.
The partnership members include ArborText, Computer Science Corporation, DEC,
Fujitsu, Hewlett-Packard, IBM, InContext, InterLeaf, Rank Xerox, Sun and Xerox.
Several of these companies are also customers. These relationships each
generally call for coordinated marketing activities, the cross provision of
hardware and software at discounts or as no charge loans to facilitate tighter
integration between complementary product offerings, and joint sales calls,
where multi-company solutions are appropriate to a particular customer's needs.
CSC, Rank Xerox, and Sun have directly distributed InterCAP products through
several of their sales channels, and Fujitsu imbeds certain InterCAP technology
in several of its own product offerings.


Employees

     As of September 30, 1994, InterCAP employed 36 persons on a full time
basis, including three in its office in Germany and four in its office in
Switzerland. InterCAP also employs several part-time employees. InterCAP
believes its employee relations are good.


Properties

     InterCAP's headquarters are located in an office building in Annapolis,
Maryland, where InterCAP leases approximately 8,000 square feet of office space.
This lease expires in September of 1995. InterCAP also leases approximately
1,200 square feet of office space in each of its offices in Germany and
Switzerland.

                    DESCRIPTION OF INTERGRAPH CAPITAL STOCK


     The authorized capital stock of Intergraph consists of 100,000,000 shares
of Intergraph Common Stock, $.10 par value.  As of September 30, 1994, there
were 44,644,003 shares of Intergraph Common Stock outstanding.


Intergraph Common Stock

     Holders of Intergraph Common Stock are entitled to one vote for each share
held on all matters submitted to a vote of stockholders and do not have
cumulative voting rights.  If a quorum is present, the affirmative vote of a
majority of the shares represented constitutes an act of the stockholders,
including the election of directors.  Holders of Intergraph Common Stock are
entitled to receive ratably such dividends, if any, as may be declared by the
Board of Directors out of funds legally available therefor.  Intergraph has
never, however, paid dividends on the

                                      -79-
<PAGE>
 
Intergraph Common Stock and does not expect to pay dividends in the foreseeable
future.  See "Risk Factors."  Upon the liquidation, dissolution or winding up of
Intergraph, the holders of Intergraph Common Stock are entitled to receive
ratably the net assets of Intergraph available after the payment of all debts
and other liabilities.  The outstanding shares of Intergraph Common Stock are,
and the shares of Intergraph Common Stock issued in the Merger will be, duly
authorized, fully paid and nonassessable.


Stockholder Rights Plan

     On August 25, 1993, the Board of Directors of Intergraph declared a
dividend distribution of one right (a "Right") for each outstanding share of
Intergraph Common Stock (the "Common Shares") of Intergraph.  The distribution
was payable on September 7, 1993 (the "Rights Record Date") to the stockholders
of record as of the close of business on the Rights Record Date.  Each Right
entitles the registered holder to purchase from Intergraph one Common Share at a
price of $50.00 (the "Purchase Price"), subject to adjustment.  The description
and terms of the Rights are set forth in a Rights Agreement, dated August 25,
1993 (the "Rights Agreement"), between Intergraph and Harris Trust and Savings
Bank, as Rights Agent (the "Rights Agent").

     The following is a general description only and is subject to the detailed
terms and conditions of the Rights Agreement.

     Rights Evidenced by Intergraph Common Stock

     Until the earlier to occur of (i) the close of business on the tenth
calendar day following a public announcement that a person or group of
affiliated or associated persons has acquired, or obtained the right to acquire,
beneficial ownership of 15% or more of the outstanding Common Shares (an
"Acquiring Person"), and (ii) the close of business on the tenth business day
(or such later date as may be specified by the Board of Directors) following the
commencement of a tender offer or exchange offer by a person or group of
affiliated or associated persons, the consummation of which would result in
beneficial ownership by such person or group of 15% or more of the outstanding
Common Shares (the earlier of such dates being hereinafter called the
"Distribution Date"), the Rights will be evidenced, with respect to any of the
Common Share certificates outstanding as of the Rights Record Date, by such
Common Share certificates.

     The Rights Agreement provides that, until the Distribution Date, the Rights
will be transferred with and only with the Common Shares.  Until the
Distribution Date (or earlier redemption or expiration of the Rights), new
Common Share certificates issued after the Rights Record Date upon transfer or
new issuance of Common Shares will contain a notation incorporating the Rights
Agreement by reference.  Until the Distribution Date (or earlier redemption or
expiration of the Rights), the surrender for transfer of any certificates for
Common Shares in respect of which Rights have been issued will also constitute
the transfer of the Rights associated with the Common Shares represented by such
certificates.  As soon as practicable following the Distribution Date, separate
certificates evidencing the Rights (the "Right

                                      -80-
<PAGE>
 
Certificates") will be mailed to holders of record of the Common Shares as of
the close of business on the Distribution Date and such separate Right
Certificates alone will evidence the Rights.

     Exercise of Rights Certificates; Expiration of Rights

     No Right is exercisable at any time prior to the Distribution Date.  The
Rights will expire on September 7, 2003 (the "Final Expiration Date") unless
earlier redeemed or exchanged by Intergraph as described below.  Until a Right
is exercised, the holder thereof, as such, will have no rights as a stockholder
of Intergraph, including without limitation the right to vote or to receive
dividends.

     Adjustment to Prevent Dilution

     The Purchase Price payable, and the number of Common Shares or other
securities issuable, upon exercise of the Rights are subject to adjustment from
time to time to prevent dilution (i) in the event of a stock dividend on, or a
subdivision, combination or reclassification of, the Common Shares, (ii) upon
the grant to holders of the Common Shares of certain rights or warrants to
subscribe for or purchase Common Shares at a price, or securities convertible
into Common Shares with a conversion price, less than the then current market
price of the Common Shares or (iii) upon the distribution to holders of the
Common Shares of evidences of indebtedness or cash (excluding regular periodic
cash dividends), assets, stock (excluding dividends payable in Common Shares) or
of subscription rights or warrants (other than those referred to above).

     Protection Against Certain Unfair Two-Step or Coercive Transactions; Right
     to Buy Intergraph Common Stock at Half Price

     In the event (a "Flip-in Event") that (i) any person or group of affiliated
or associated persons becomes the beneficial owner of 15% or more of the
outstanding Common Shares, or (ii) any Acquiring Person merges into or combines
with Intergraph and Intergraph is the surviving corporation, proper provision
shall be made so that each holder of a Right, other than Rights that are or were
owned beneficially by the Acquiring Person (which, from and after the later of
the Distribution Date and the date of the earlier of either of such events, will
be void), will thereafter have the right to receive, upon exercise thereof at
the then current exercise price of the Right, that number of Common Shares (or,
under certain circumstances, an economically equivalent security or securities
or assets of Intergraph) having a market value of two times the exercise price
of the Right.

     To illustrate the operation of such an adjustment, at a Purchase Price of
$16.00, assuming the current market price (as determined pursuant to the
provisions of the Rights Agreement) per Common Share was $8.00, each Right not
owned beneficially by an Acquiring Person at or after the time of such an
occurrence would entitle its holder to purchase (after the Distribution Date)
from Intergraph four Common Shares (having a market value of $32.00) for $16.00.

                                      -81-
<PAGE>
 
     In the event (a "Flip-over Event") that, following the first date of public
announcement that a person has become an Acquiring Person, (i) Intergraph merges
with or into any person and Intergraph is not the surviving corporation, (ii)
any person merges with or into Intergraph and Intergraph is the surviving
corporation, but its Common Shares are changed or exchanged, or (iii) 50% or
more of Intergraph's assets or earning power, including without limitation
securities creating obligations of Intergraph, are sold, proper provision shall
be made so that each holder of a Right will thereafter have the right to
receive, upon the exercise thereof at the then current exercise price of the
Right, that number of shares of common stock (or, under certain circumstances,
an economically equivalent security or securities) of such other person which at
the time of such transaction would have a market value of two times the exercise
price of the Right.

     At any time after the later of the Distribution Date and the first
occurrence of a Flip-in Event or Flip-over Event and prior to the acquisition by
any person or group of affiliated or associated persons of 50% or more of the
outstanding Common Shares, the Board of Directors of Intergraph may exchange the
Rights (other than any Rights which have become void), in whole or in part, at
an exchange ratio of one Common Share per Right (subject to adjustment).

     With certain exceptions, no adjustment in the Purchase Price will be
required until cumulative adjustments require an adjustment in the Purchase
Price of at least 1%.  Intergraph is not required to issue fractional Common
Shares or other securities issuable upon the exercise of Rights.  In lieu of
issuing such securities, Intergraph may make a cash payment, as provided in the
Rights Agreement.

     Redemption

     Intergraph may redeem the Rights in whole, but not in part, at a price of
$0.01 per Right (the "Redemption Price"), at any time prior to the close of
business on the earlier of (i) the Distribution Date and (ii) the Final
Expiration Date.  Immediately upon any redemption of the Rights, the right to
exercise the Rights will terminate and the only right of the holders of Rights
will be to receive the Redemption Price.

     Amendment of Intergraph Rights Plan

     The Rights Agreement may be amended by the Board of Directors in any manner
prior to the Distribution Date without the approval of any holders of
certificates representing Common Shares.  After the Distribution Date, the
Rights Agreement may be amended by the Board of Directors without the approval
of any holders of Right Certificates, including amendments which add other
events requiring adjustment to the Purchase Price payable and the number of
Common Shares or other securities issuable or property purchasable upon the
exercise of the Rights or which modify procedures relating to the redemption of
the Rights, provided that no amendment may be made which decreases the stated
Redemption Price or the period of time remaining until the Final Expiration Date
or which modifies a time period relating to when the Rights may be redeemed at
such time as the Rights are not then redeemable.  Under certain circumstances
set

                                      -82-
<PAGE>
 
forth in the Rights Agreement, the Rights Agreement may only be amended by
action of the Independent Directors (defined as any director who is not an
officer or employee of Intergraph and (i) who was a director prior to August 25,
1993, and is not an Acquiring Person, an affiliate or associate thereof or a
representative of any Acquiring Person, affiliate or associate, or (ii) who
becomes a director after August 25, 1993 and is not an Acquiring Person, an
affiliate or associate thereof or a representative of any Acquiring Person,
affiliate or associate and who is recommended or nominated for election to the
Board of Directors by a majority of the Independent Directors).

     Certain Change in Control Effects

     The Rights have certain anti-takeover effects.  The Rights will cause
substantial dilution to a person or group that attempts to acquire Intergraph on
terms not approved by the Board of Directors, except pursuant to an offer
conditioned on a substantial number of Rights being acquired.  However, the
Rights should not interfere with any merger or other business combination
approved by the Board of Directors since (subject to the limitations described
above) the Rights may be redeemed by Intergraph at the Redemption Price prior to
the Distribution Date, subject to extension by a majority of the Independent
Directors.  Thus, the rights are intended to encourage persons who may seek to
acquire control of Intergraph to initiate such an acquisition through
negotiations with the Board of Directors.  However, the effect of the Rights may
be to discourage a third party from making a partial tender offer or otherwise
attempting to obtain a substantial equity position in the Common Shares of, or
seeking to obtain control of, Intergraph.  To the extent any potential acquirors
are deterred by the Rights, the Rights may have the effect of preserving
incumbent management in office.

     As of September 30, 1994, there were 44,644,003 Common Shares issued and
outstanding and 4,222,368 Common Shares reserved for issuance pursuant to
employee benefit plans.  As long as the Rights are attached to the Common
Shares, Intergraph will issue one Right with each new Common Share so that all
such Common Shares will have Rights attached.

     The Rights Agreement, which includes the form of Right Certificate as an
exhibit thereto, and the form of press release announcing the declaration of the
dividend distribution of the Rights are filed as exhibits to the Registration
Statement of which this Prospectus/Proxy Statement is a part and are
incorporated herein by this reference.  The foregoing description of the Rights
does not purport to be complete and is qualified in its entirety by reference to
such exhibits.


Delaware Law and Certain Charter and By-law Provisions

     Indemnification

     Intergraph's Certificate of Incorporation includes provisions eliminating
the personal liability of Intergraph's directors for monetary damages resulting
from breaches of their fiduciary duties to the extent permitted by Delaware law.
Intergraph's Certificate of Incorporation and

                                      -83-
<PAGE>
 
Restated By-laws include provisions indemnifying Intergraph's directors and
officers to the fullest extent permitted by Delaware law, including under
circumstances in which indemnification is otherwise discretionary, and
permitting the Board of Directors to grant indemnification to employees and
agents to the fullest extent permitted by Delaware law.

     Nominations of Directors and Stockholder Proposals

     Intergraph's Restated By-laws require that nominations for the Board of
Directors made by a stockholder and proposals by stockholders seeking to have
any business conducted at a stockholders' meeting comply with particular notice
procedures.  A notice by a stockholder of a planned nomination or of proposed
business must generally be given not later than 60 days nor earlier than 90 days
prior to the date of the meeting.  A stockholder's notice of nomination must
include particular information about the stockholder, the nominee and any
beneficial owner on whose behalf the nomination is made and a notice from a
stockholder proposing business to be brought before the meeting must describe
such business and include information about the stockholder making the proposal,
any beneficial owner on whose behalf the proposal is made, and any other
stockholder known to be supporting the proposal.

     Delaware's Anti-Takeover Law

     Intergraph is subject to the provisions of Section 203 of the Delaware Act.
In general Section 203 prohibits certain publicly held Delaware corporations
from engaging in a "business combination" with an "interested stockholder" for a
period of three years after the date of the transaction in which the person or
entity became an interested stockholder, unless, among other exceptions, (i) the
business combination is approved by the Board of Directors prior to the date the
interested stockholder attained such status, or by the holders of two-thirds of
the outstanding voting stock not owned by the interested stockholder or (ii) the
interested stockholder acquired 85% or more of the outstanding voting stock of
Intergraph in the transaction.  For purposes of Section 203, a "business
combination" is defined broadly to include mergers, asset sales and other
transactions resulting in a financial benefit to the interested stockholder.
Subject to certain exceptions, an "interested stockholder" is a person or entity
who, together with affiliates and associates, owns, or within the three
immediately preceding years of a business combination did own, 15% of the
corporation's outstanding voting stock.

     Actions by Stockholders

     Intergraph's Restated By-laws provide that any action required or permitted
to be taken by the stockholders of Intergraph shall be taken only at a duly
called annual or special meeting of the stockholders, or by the written consent
of all stockholders entitled to vote.  Special meetings may be called only by
the Board of Directors or the Chief Executive Officer of Intergraph.  In
addition, Intergraph's Restated Bylaws provides that the Board of Directors may,
from time to time, fix the number of directors constituting the Board of
Directors, and only the directors are permitted to fill vacancies on the Board
of Directors.

                                      -84-
<PAGE>
 
     Amendment of Certificate of Incorporation and Restated By-laws

     The Delaware Act provides generally that the affirmative vote of a majority
of the shares entitled to vote on any matter is required to amend a
corporation's certificate of incorporation or by-laws, unless a corporation's
certificate of incorporation or by-laws, as the case may be, requires a greater
percentage.  Neither the Certificate of Incorporation nor the Restated By-laws
of Intergraph require a higher percentage.

     Effect on Change in Control

     The provisions of the Certificate of Incorporation and Restated By-laws
discussed above and under "Management of Intergraph" in Intergraph's definitive
Proxy Statement for the Annual Meeting of Stockholders held May 12, 1994 could
make more difficult or discourage a proxy contest or the acquisition of control
by a holder of a substantial block of Intergraph Common Stock or the removal of
any incumbent member of the Board of Directors.  Such provisions could also have
the effect of discouraging a third party from making a tender offer or otherwise
attempting to obtain control of Intergraph, even though such an attempt might be
beneficial to Intergraph and its stockholders.

InterCAP Common Stock

     Holders of InterCAP Common Stock are entitled to one vote for each share
held of record on all matters submitted to a vote of the stockholders.  Holders
of InterCAP Common Stock are entitled to such dividends as may be declared by
the Board of Directors out of funds legally available therefor, subject to prior
dividend rights of the outstanding InterCAP Preferred Stock.  Shares of InterCAP
Common Stock have no conversion, preemptive or other rights to subscribe for
additional shares and are not subject to redemption, except that shares of
InterCAP Common Stock issued upon conversion of the InterCAP Preferred Stock
have the same preemptive rights as shares of InterCAP Preferred Stock.  All of
the outstanding shares of InterCAP Common Stock are fully paid and
nonassessable.

     As of September 30, 1994, 2,911,478 shares of InterCAP Common Stock were
issued and outstanding and held of record by 79 stockholders.


InterCAP Preferred Stock

     InterCAP is currently authorized to issue 1,872,938 shares of InterCAP
Series A Preferred Stock, 2,000,000 shares of InterCAP Series B Preferred Stock
and 953,442 shares of InterCAP Series C Preferred Stock.  As of September 30,
1994, 927,326 shares of the InterCAP Series A Preferred Stock, 1,716,387 shares
of InterCAP Series B Preferred Stock and all the shares of the InterCAP Series C
Preferred Stock were issued and outstanding and were held of record by four
stockholders.

     Conversion

     Holders of InterCAP Preferred Stock are entitled to convert each share of
InterCAP Preferred Stock at any time into fully paid and nonassessable shares of
InterCAP Common Stock without payment of additional consideration.  The InterCAP
Preferred Stock is convertible into the number of shares of InterCAP Common
Stock which results from dividing the applicable "Conversion Price" per share in
effect at the time of conversion into $1.475 for each share of InterCAP Series A
Preferred Stock being converted, into $.50 for each share of InterCAP Series B
Preferred Stock being converted and into $.65552 for each share of InterCAP
Series C Preferred Stock being converted.  The initial Conversion Prices per
share of the InterCAP Series A Preferred Stock, InterCAP Series B Preferred
Stock and InterCAP Series C Preferred Stock were $1.475, $.50 and $.65552,
respectively.

     The initial Conversion Price per share for each series of InterCAP
Preferred Stock is subject to adjustment in the event of any stock split, stock
dividend, reclassification, merger, sale of assets, sale of shares of InterCAP
Common Stock (or InterCAP Common Stock equivalents) below the Conversion Price
(other than under InterCAP's stock option plans or other stock purchase
arrangements approved by InterCAP's Board of Directors, conversion of the
InterCAP Preferred Stock or exercise of the InterCAP Warrants) or other similar
event affecting the

                                      -86-
<PAGE>
 
InterCAP Common Stock.  As of September 30, 1994, the Conversion Price per share
of InterCAP Series A Preferred Stock had been adjusted to approximately $1.11
per share, making each share of the InterCAP Series A Preferred Stock
convertible into 1.3329 shares of InterCAP Common Stock.

     Each share of InterCAP Preferred Stock will automatically be converted into
shares of InterCAP Common Stock upon the closing of an underwritten public
offering of InterCAP Common Stock pursuant to an effective registration
statement filed under the Securities Act in which the public offering price per
share, when multiplied by the number of shares of InterCAP Common Stock
outstanding immediately after such public offering on a fully diluted basis,
equals or exceeds $15,000,000.

     Voting Rights

     In general, holders of InterCAP Preferred Stock vote together with holders
of InterCAP Common Stock on all matters submitted to a vote of stockholders.
Each holder of InterCAP Preferred Stock is entitled to the number of votes on
stockholder matters equal to the number of shares of InterCAP Common Stock into
which such holder's shares of InterCAP Preferred Stock can be converted on the
record date for the matter to be voted upon.  In addition, the consent of the
holders of at least a majority of the InterCAP Series A Preferred Stock (voting
separately), at least a majority of the InterCAP Series A Preferred Stock and
InterCAP Series B Preferred Stock (voting as a single class), at least a
majority (and in certain cases at least 66.67%) of the InterCAP Preferred Stock
(voting as a single class) and at least of a majority of the InterCAP Series C
Preferred Stock (voting separately) is required as specified in the InterCAP
Certificate for any redemption of the InterCAP Preferred Stock other than on the
terms set forth in the InterCAP Certificate, any redemption of InterCAP Common
Stock (subject to certain exceptions), any issuance by InterCAP of any equity
security senior to or on a parity with the InterCAP Preferred Stock as to
dividend, redemption and liquidation rights, any sale of all or substantially
all the assets of InterCAP, any merger or consolidation of InterCAP, any
reclassification or recapitalization of InterCAP, any sale of stock by an
InterCAP subsidiary, any increase or decrease in the total number of authorized
shares of InterCAP Preferred Stock, any issuance of securities by InterCAP for
property other than cash or any amendment to the InterCAP Certificate or its 
By-Laws.

     Dividends

     Holders of InterCAP Preferred Stock are entitled to receive when, as and if
declared by the Board of Directors of InterCAP out of funds of InterCAP legally
available for the payment of dividends, cumulative dividends at the annual rate
of $.1475 per share of InterCAP Series A Preferred Stock, $.05 per share of
InterCAP Series B Preferred Stock and $.065552 per share of InterCAP Series C
Preferred Stock.  As of June 30, 1994, the accrued but unpaid dividends on the
InterCAP Series A Preferred Stock totaled approximately $.82 per share in the
case of 339,068 shares and approximately $.79 per share in the case of the
remaining 576,272 shares of InterCAP Series A Preferred Stock.  As of June 30,
1994, the accrued but unpaid dividends on

                                      -87-
<PAGE>
 
the InterCAP Series B Preferred Stock and the InterCAP Series C Preferred Stock
totalled approximately $.17 per share and approximately $.17 per share,
respectively.  After payment in full of all cumulative dividends on the InterCAP
Preferred Stock, each holder of InterCAP Preferred Stock is entitled to
participate in any dividends declared and paid on the InterCAP Common Stock on
the basis of the number of shares of InterCAP Common Stock into which the
InterCAP Preferred Stock is convertible on the record date for such dividend.
To date, no dividends have been declared or paid on any capital stock of
InterCAP.

     Liquidation

     Holders of InterCAP Series C Preferred Stock have a liquidation preference
senior to the holders of InterCAP Series A Preferred Stock, InterCAP Series B
Preferred Stock and InterCAP Common Stock equal to $.65552 per share, plus all
accrued and unpaid dividends thereon.  Holders of InterCAP Series B Preferred
Stock have a liquidation preference senior to the holders of InterCAP Series A
Preferred Stock and InterCAP Common Stock equal to $.5978 per share, plus an
amount equal to one-half of all accrued and unpaid dividends thereon from
January 1, 1993 to the effective date of the liquidation.  Holders of InterCAP
Series A Preferred Stock have a liquidation preference senior to the holders of
InterCAP Common Stock equal to $1.475 per share, plus an amount equal to 
one-half of all accrued but unpaid dividends thereon if the effective date of
the liquidation is after October 1, 1994. Pursuant to the Charter Amendment, the
liquidation preference of the InterCAP Series A Preferred Stock would be amended
to provide that the liquidation preference will be $1.475 per share unless the
effective date of the liquidation is after January 15, 1995, in which case the
liquidation preference for the InterCAP Series A Preferred Stock would be $1.475
per share, plus an amount equal to all accrued and unpaid dividends thereon. See
"Proposal to Amend InterCAP's Certificate of Incorporation." After the payment
in full of all such liquidation preferences, if the net assets of InterCAP
available for distribution to its stockholders are $5,000,000 or less, the
holders of InterCAP Preferred Stock and InterCAP Common Stock share ratably per
share in any remaining proceeds.

     Redemption
    
     The InterCAP Certificate provides that InterCAP must redeem the InterCAP
Preferred Stock in three equal annual installments commencing January 2, 1994,
at a redemption price of $1.475 per share of InterCAP Series A Preferred Stock,
$.50 per share of InterCAP Series B Preferred Stock and $.65552 per share of
InterCAP Series C Preferred Stock, plus in all cases all accrued but unpaid
dividends thereon.  Holders of InterCAP Series C Preferred Stock have a
redemption preference senior to the holders of InterCAP Series A Preferred Stock
and InterCAP Series B Preferred Stock.  Holders of InterCAP Series B Preferred
Stock have a redemption preference senior to InterCAP Series A Preferred Stock.
Any redemption of InterCAP Preferred Stock is to be funded by use of a sinking
fund.  Pursuant to InterCAP's Certificate, the holders of the InterCAP Preferred
Stock waived their right to have the InterCAP Preferred Stock redeemed through
January 1, 1995 and agreed that InterCAP could limit its redemption obligations
in each year to the amount of its net income in the 12-month period preceding
each redemption date. Pursuant to the letter agreement executed by the Specified
Preferred Stockholders on December 7, 1994, such holders of InterCAP Preferred 
Stock further postponed their rights in connection with the InterCAP Redemption 
Obligations through January 15, 1995.

     Preemptive Rights

     Holders of InterCAP Preferred Stock and any InterCAP Common Stock issued
upon the conversion of InterCAP Preferred Stock have the preemptive right to
purchase a pro rata portion of all issuances by InterCAP of equity securities or
warrants, rights or other options to purchase InterCAP equity securities other
than securities issued in connection with stock splits and dividends, the
InterCAP Preferred Stock or InterCAP Common Stock issued upon conversion
thereof, securities issued pursuant to any stock option plan, stock purchase
plan or similar arrangement or securities issued after a merger or public
offering by InterCAP.  The holders of a majority of the InterCAP Preferred Stock
may waive the preemptive rights with respect to any proposed issuance by
InterCAP of its securities.


Options

     For a description of the outstanding options under InterCAP's 1989 Stock
Option Plan and 1994 Non-Qualified Stock Option Program, see "The Merger and
Related Transactions--Options Outstanding Prior to the Merger."


Warrants

     At September 30, 1994, there were warrants outstanding entitling the holder
thereof to purchase up to 50,000 shares of InterCAP Common Stock at an exercise
price of $.25 per share (the "Warrants").  Pursuant to the Preferred Stock
Agreement, InterCAP and the holder of the Warrants have agreed that the Warrants
will be exercised immediately prior to the Effective Date on a cashless basis by
the holder relinquishing the right to purchase 13,740 shares of InterCAP Common
Stock under the Warrants in exchange for the issuance by InterCAP to the holder
of 36,260 shares of InterCAP Common Stock.


             PRINCIPAL DIFFERENCES BETWEEN INTERGRAPH AND INTERCAP
                                 CAPITAL STOCK


     Both Intergraph and InterCAP are Delaware corporations.  Consequently,
except for differences arising out of their respective certificates of
incorporation and by-laws and the Intergraph Rights Agreement, the rights of
holders of Intergraph Common Stock and InterCAP Common Stock are identical;
however, as outlined below, there are significant differences between the
rights, preferences and privileges of the holders of InterCAP Preferred Stock
and the holders of Intergraph Common Stock.  The comparison set forth below is
not meant to be a complete statement of the comparative rights of holders of
Intergraph Common Stock and the holders of InterCAP Common Stock and InterCAP
Preferred Stock, and the identification of specific differences between the
rights of such holders is not meant to indicate that other equally

                                      -89-
<PAGE>
 
or more significant differences do not exist.  Such differences can be
determined in full by reference to the respective corporate documents of
Intergraph and InterCAP.


Power to Call Special Stockholders' Meetings

     The Restated By-laws of Intergraph provide that only the Board of Directors
or the Chairman of the Board of Directors, in either case pursuant to a
resolution adopted by a majority of the entire Board of Directors, may call a
special meeting of stockholders.  InterCAP's By-laws permit the Board of
Directors, the Chairman of the Board or the President to call a special meeting
of stockholders.


Stockholder Rights Plan

     In August of 1993, the Board of Directors of Intergraph adopted a
Stockholder Rights Plan which is described in more detail under "Description of
Intergraph Capital Stock--Stockholder Rights Plan."  InterCAP does not have a
stockholder rights plan.


Vacancies on the Board of Directors

     Intergraph's Restated By-laws provide that only the directors remaining in
office may fill vacancies in the Board of Directors resulting from death,
resignation, retirement, disqualification or other cause.  InterCAP's By-laws
permit the remaining directors or the stockholders to fill any vacancies in the
Board of Directors.


Stockholder Approval of Certain Business Combinations

     InterCAP does not have a class of voting stock that is listed on a national
securities exchange and is therefore not subject to Section 203 of the Delaware
Act.  Intergraph Common Stock is traded on NASDAQ and, therefore, Intergraph is
subject to Section 203 of the Delaware Act.  In certain circumstances, Section
203 makes it more difficult for an acquiror to effect a business combination
with a corporation subject to its provisions.  See "Description of Intergraph
Capital Stock--Delaware Law and Certain Charter and By-law Provisions--
Delaware's Anti-Takeover Law."


Action by Consent of Stockholders

     Holders of InterCAP Stock are entitled to take action, without a meeting,
without prior notice and without a vote, if a consent in writing is signed by a
majority of the stockholders of InterCAP Stock entitled to vote on the matter
being considered.  The By-laws of Intergraph also

                                      -90-
<PAGE>
 
permit action by non-unanimous written consent in lieu of a stockholders'
meeting, but impose various requirements on the duration and effectiveness of
such written consents, permit the Board of Directors to fix a record date with
respect to such consents, establish procedures for the appointment of inspectors
of elections to review such consents (and any revocations thereof), and
prescribe procedures for challenges to the decision of the inspectors of
elections.


Stockholder Voting

     All holders of Intergraph Common Stock vote equally on all matters to be
voted on by Intergraph's stockholders, except as otherwise required by law.
Holders of InterCAP Preferred Stock will no longer have one or more separate
class votes with respect to approval of certain matters, including any merger,
consolidation, reclassification, recapitalization or sale of substantially all
of the assets, redemption or repurchase of shares of capital stock, issuance of
senior equity securities, or any amendment or modification of the certificate of
incorporation or by-laws.  Upon consummation of the Merger, holders of InterCAP
Preferred Stock will receive Intergraph Common Stock and will vote equally with
all other holders of Intergraph Common Stock.


Liquidation, Conversion, Redemption

     Upon liquidation, dissolution or winding up of InterCAP, the holders of
InterCAP Preferred Stock have certain rights to receive distribution of net
assets of InterCAP prior and in preference to any holders of InterCAP Common
Stock.  All stockholders of Intergraph would share ratably in the net assets of
Intergraph upon the occurrence of any such event.  In addition, holders of
InterCAP Preferred Stock will lose all conversion and redemption rights provided
in the InterCAP Certificate.

                         Report of Independent Auditors


Board of Directors
InterCAP Graphics Systems, Inc.


We have audited the accompanying consolidated balance sheets of InterCAP
Graphics Systems, Inc. as of June 30, 1994 and 1993, and the related
consolidated statements of operations, shareholders' equity, and cash flows for
each of the three years in the period ended June 30, 1994.  These financial
statements are the responsibility of the Company's management.  Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the consolidated financial position of
InterCAP Graphics Systems, Inc. at June 30, 1994 and 1993, and the consolidated
results of its operations and its cash flows for each of the three years in the
period ended June 30, 1994, in conformity with generally accepted accounting
principles.

As discussed in Note 2 to the financial statements, in 1994 the Company changed
its method of accounting for income taxes.

                  Notes to Consolidated Financial Statements

                                 June 30, 1994

1. Description of Business

InterCAP Graphics Systems, Inc. (InterCAP) develops, licenses and supports
proprietary computer software and interfaces designed to be used on workstation
computers for the illustration of technical documents produced by computer-aided
publishing software systems. Revenues are derived from sales in the United
States and Europe.

2. Accounting Policies

Principles of Consolidation

The consolidated financial statements include the accounts of InterCAP and its
subsidiaries, all of which are wholly-owned.  All intercompany balances and
transactions have been eliminated in consolidation.

Computer Software and Other Assets

Software development costs are capitalized upon the establishment of
technological feasibility. Amortization of such costs (approximately $562,000,
$494,000  and $403,000 during 1994, 1993 and 1992, respectively) is provided on
a product-by-product basis at the greater of (a) the ratio of current gross
revenue from the product to the sum of current and anticipated gross revenues or
(b) the straight-line method over the remaining estimated economic life of the
product. Generally an estimated economic life of five years is assigned to
capitalized software development costs. Amortization of other assets is provided
on a straight-line basis over the estimated useful lives ranging from five to
ten years.

Revenue Recognition

Revenues derived from initial license fees are recognized upon delivery of the
software.  License renewal fees are recognized as revenue on the annual renewal
date of the license.  Costs are accrued for unfulfilled obligations upon
delivery of the software which have historically not been material.  Service
revenues, comprised of consulting and training fees, are recognized upon
delivery of the services.  Revenue recognition is subject to the collectibility
of such amounts.  Licenses are sold, generally on credit, to independent users
in the United States and Europe.  InterCAP performs ongoing credit evaluations 
of its customers and generally does not require collateral.

2. ACCOUNTING POLICIES (CONTINUED)
 
FURNITURE AND EQUIPMENT
 
Furniture and equipment are stated at cost and depreciated using the straight-
line method over estimated useful lives ranging from three to five years.
Depreciation expense was approximately $104,000, $122,000 and $119,000 during
the years ended June 30, 1994, 1993 and 1992, respectively.
 
INCOME TAXES
 
Effective July 1, 1993, the Company adopted Statement of Financial Accounting
Standards (FAS) 109, "Accounting for Income Taxes."  FAS 109 requires a change
from the deferred to the liability method of accounting for deferred income
taxes.  As permitted by the Statement, prior year financial statements have not
been restated.  There was no cumulative effect as a result of adopting FAS 109.
 
FOREIGN CURRENCY TRANSLATION
 
The financial statements of foreign subsidiaries have been translated in U.S.
dollars in accordance with FAS 52, "Foreign Currency Translation."  Assets and
liabilities of foreign operations are translated into U.S. dollars at the rates
of exchange at the balance sheet dates and the effects of translation
adjustments are deferred and included as a component of shareholders' equity.
Revenues and expenses are translated into U.S. dollars using weighted average
exchange rates.  The effects on the statements of operations of transaction
gains are approximately $34,000, $7,000 and $59,000 for the years ended June 30,
1994, 1993 and 1992, respectively, and are included in other income on the
financial statements.
 
NET LOSS PER SHARE
 
Net loss per common share is computed using the weighted average number of
common shares outstanding during the period.  Other shares issuable upon the
exercise of stock options and warrants or conversion of preferred stock have
been excluded from the computation because the effect of their inclusion would
be anti-dilutive.  Cumulative dividends on preferred shares were deducted from
net income in computing the net loss per share.

5. RELATED PARTY TRANSACTIONS
 
In conjunction with a repurchase of 801,951 shares of common stock and 100,000
shares of Series B preferred stock, the Company borrowed $225,000 from two
related parties in April, 1992.  These related parties guaranteed the bank loan
outstanding at June 30, 1993 in return for a fee equal to the difference between
12% and the loan's interest rate, prime rate plus 2%, multiplied by the
outstanding principal.  In addition, the related parties were given warrants to
purchase 162,709 shares of common stock at $0.10 per share.  These warrants
expire April, 1997 (Note 7).
 
During April 1993, two other related parties loaned the Company $200,000 for
operating purposes.  These related parties were given warrants to purchase
81,354 shares of common stock at $0.10 per share expiring April 1998 (Note 7).
The total balance due to related parties plus interest at 12% was repaid during
1994, $402,797 in cash and $22,203 through the exercise of warrants to purchase
222,031 shares of common stock.
 
Interest expense incurred during 1994, 1993 and 1992 related to the above
transactions was $36,000, $38,500 and $6,200, respectively.
 
6. REDEEMABLE PREFERRED SHARES
 
The Company has authorized 10,000,000 preferred shares of which 1,876,480 were
designated Series A Convertible Preferred.  Series A shares are convertible into
common shares at a 1.3329 to 1 ratio, subject to adjustment for any sales of
common equivalents at less than $.50 per share. Series A shares also carry
specific liquidation rights which waive dividends until October 1, 1994 from
which point the forfeited dividends shall be restated retroactively to the time
of purchase (December 1988) at an annual rate of $.07375 per share.  At June 30,
1994, undeclared, cumulative dividends of approximately $735,000 were unpaid.
InterCAP may be required to redeem (at $1.475 per share plus accrued dividends)
the Series A shares, in three equal annual installments beginning January 1995,
unless the holders elect to convert such shares to common. Maximum mandatory
redemption amounts are limited to the Company's earnings during the preceding 12
months. Any such redemption is subject to the redemption rights of the Series B
shareholders and Series C shareholders.

6. REDEEMABLE PREFERRED SHARES (CONTINUED)

The Company designated 1,797,300 of the authorized preferred shares as Series B
Convertible Preferred.  The Series B shares are convertible into common shares
at a 1 to 1 ratio, subject to anti-dilution adjustments. The Series B shares
carry liquidation preferences of $.50 per share and rank similar to the Series A
shares as to dividends.  Increases in liquidation preferences were waived from
January 1, 1993 through October 1, 1994.  Dividends accrue at an annual rate of
$.05 per share until October 1, 1994.  On October 1, 1994 and thereafter, the
liquidation preference will be $.5978 per share plus one half accrued and unpaid
dividends and dividends will be restated at an annual rate of $.025 per share,
rather than $.05 per share. At June 30, 1994, cumulative dividends of
approximately $151,000 ($0.08 per share) were unpaid. InterCAP may be required
to redeem the Series B shares in three equal annual installments beginning
January 1995 at $.50 per share plus any accrued dividends, unless the holders
elect to convert such shares to common. Maximum mandatory redemption amounts are
limited to the Company's earnings during the preceding 12 months, and are junior
to the rights of the Series C preferred shares.
 
The Company designated 953,442 shares as Series C Convertible Preferred.  The
Series C shares are convertible into common shares at a 1 to 1 ratio, subject to
anti-dilution adjustments. Upon liquidation, the Series C preferred shareholders
receive $0.65552 per share plus declared and unpaid dividends before Series A,
Series B, and common stock shareholders are entitled to receive money for their
shares. Series C shareholders rank similar to Series A and Series B
shareholders, with respect to dividends (which accrue at the annual rate of
$0.065552 per share).  At June 30, 1994, cumulative dividends of approximately
$160,000 ($0.17 per share) were unpaid. InterCAP may be required to redeem the
Series C shares in three equal annual installments beginning January 1995 at
$0.65552 per share plus any accrued dividends, unless the shareholders elect to
convert such shares to common. Maximum mandatory redemption amounts are limited
to the Company's earnings during the preceding 12 months.
 
The preferred shareholders are entitled to the number of votes equal to the
largest number of full common shares into which such shares of preferred stock
could be converted.  In connection with the sale of the Series A, B, and C
shares, InterCAP agreed to certain covenants including restrictions on loans to
and investments in others, mergers and acquisitions, creation of indebtedness,
capital expenditures, redemption of capital stock, and cash or property
dividends on common shares.

7. SHAREHOLDERS' EQUITY
 
The Company has a Stock Option Plan which provides for 2,500,000 shares of
common stock to be granted under the Plan.  The purpose of the Plan is to
compensate various key executives and key employees for services rendered to or
on behalf of the Company.  Under the plan, options generally vest at the rate of
25% each year beginning one year from the date of grant.  There are 431,255 such
options vested and outstanding at June 30, 1994 exercisable at prices ranging
from $0.10 to $0.42.
 
The following table summarizes the option activity for the years ended June 30:

8.  INCOME TAXES
 
At June 30, 1994 InterCAP has net operating loss carryforwards (NOL) of
approximately $1,478,000 and a general business credit carryforward of $278,000
expiring on varying dates through 2008.  In addition, the Company has an
alternative minimum tax carryforward of approximately $31,000 with no expiration
date.
 
Deferred income taxes reflect the net tax effects of net operating loss and
alternative minimum tax carryforwards, research credits and temporary
differences between the carrying amounts of assets and liabilities for financial
reporting purposes and the amounts used for income tax purposes.  Significant
components of the Company's deferred tax assets and liability at June 30, 1994
are as follows:

10. 401(k) PLAN
 
Effective August 31, 1987, the Company adopted a defined contribution and
profit-sharing plan. This plan, which covers substantially all employees,
stipulates that employees may elect an amount between 2% and 15% of their total
compensation to contribute to the plan.
 
At the end of each plan year, the Company, at its discretion, may make a profit-
sharing contribution to the plan, which would be allocated to the accounts of
all eligible employees on the basis of their compensation. All employees who are
participants during the plan year and are employed by the Company on the last
day of the plan year would be eligible to share in the profit-sharing
contribution. No contributions have been made by the Company to the plan for the
three years in the period ended June 30, 1994.
 
11. SUBSEQUENT EVENT
 
On September 30, 1994, the Company entered into an agreement and plan of
reorganization with Intergraph Corporation whereby the Company will become a
wholly-owned subsidiary of Intergraph in a transaction which is expected to be
accounted for as a purchase transaction.

and sufficiency of which are hereby acknowledged, the parties, intending to be
legally bound, hereby agree as follows:


                                   ARTICLE I.

                                   THE MERGER

     SECTION 1.1  The Merger.  Upon the terms and subject to the conditions
                  ----------                                               
hereof, and in accordance with the General Corporation Law of the State of
Delaware (the "GCL"), Intergraph Subsidiary shall be merged with and into
InterCAP (the "MERGER") and InterCAP shall become a wholly-owned subsidiary of
Intergraph as soon as practicable following the satisfaction or waiver, if
permissible, of the conditions set forth in Article VII hereof.  Following the
Merger, InterCAP shall continue as the surviving corporation with the name
InterCAP Graphics Systems, Inc. (the "SURVIVING CORPORATION") and the separate
corporate existence of Intergraph Subsidiary shall cease.  (Intergraph
Subsidiary and InterCAP are sometimes referred to as the "CONSTITUENT
CORPORATIONS".)

     SECTION 1.2  Effective Time.  The Merger shall be consummated by the filing
                  --------------                                                
with the Delaware Secretary of State of a Certificate of Merger in the form
attached hereto as Exhibit A in accordance with the relevant provisions of the 
GCL and by the certification by the 

                                       1
<PAGE>
 
Secretary of State of Delaware that the Certificate of Merger has been filed
in such office.  (The date and time of such issuance and filing or such other
time and date as may be specified in the Certificate of Merger shall be the
"EFFECTIVE TIME").

     SECTION 1.3  Certain Effects of the Merger.  The Merger shall have the
                  -----------------------------                            
effects set forth in Section 259 of the GCL.

     SECTION 1.4  Certificate of Incorporation and By-Laws.  The Certificate of
                  ----------------------------------------                     
Incorporation and the By-Laws of Intergraph Subsidiary, in each case as in
effect at the Effective Time, shall be the Certificate of Incorporation and By-
Laws of the Surviving Corporation, except that the name of the Surviving
Corporation shall be as specified in Section 1.1.

     SECTION 1.5  Directors and Officers.  The directors and officers of
                  ----------------------                                
Intergraph Subsidiary at the Effective Time shall be the directors and officers
of the Surviving Corporation and shall hold office from the Effective Time until
their respective successors are duly elected or appointed and qualified in the
manner provided in the Certificate of Incorporation and By-Laws of the Surviving
Corporation, or as otherwise provided by law.

     SECTION 1.6  Tax-Free Reorganization.  For federal income tax purposes, the
                  -----------------------                                       
parties intend that the Merger be treated as a tax-free reorganization within
the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended
(the "CODE").  Except for cash paid in lieu of fractional shares, no
consideration that could constitute "other property" within the meaning of
Section 356(b) of the Code is being transferred by Intergraph for the InterCAP
Stock (as defined in Section 2.1) in the Merger.  The parties shall not take a
position on any tax return inconsistent with this Section 1.6.

     SECTION 1.7  Stockholders' Communications.  InterCAP, acting through its
                  ----------------------------                               
Board of Directors, shall, in accordance with applicable law:

          (a) duly call, give notice of, convene and hold a meeting (the
"STOCKHOLDERS' MEETING") of its stockholders as soon as practicable after the
Form S-4 (as defined below) has been declared effective, for the purpose of
approving and adopting this Agreement and the transactions contemplated thereby;

          (b) include in the Proxy Statement (as defined in paragraph (c) below)
the unanimous recommendation of its Board of Directors that the stockholders of
InterCAP vote in favor of the approval and adoption of this Agreement and the
transactions contemplated hereby;

          (c) (i) obtain and furnish the information required to be included by
it in the Proxy Statement and cause the Proxy Statement to be mailed to its
stockholders at the earliest practicable time following the effectiveness of the
Form S-4, and (ii) use its best efforts to obtain the approval and adoption of
the Merger by all of InterCAP's stockholders.  The letter to stockholders,
notice of Stockholder's Meeting, proxy statement (together with the prospectus

                                       2
<PAGE>
 
portion of the registration statement on Form S-4 (the "FORM S-4") registering
the Intergraph Common Stock to be issued in the Merger under the Securities Act
of 1933, as amended (the "SECURITIES ACT")), and form of proxy to be distributed
to stockholders in connection with the Merger shall be in form and substance
reasonably satisfactory to Intergraph, and are collectively referred to herein
as the "PROXY STATEMENT";

          (d) permit the exercise of the Warrants (as defined in Section 3.3),
and the conversion of certain shares of InterCAP Preferred Stock (as hereafter
defined) into InterCAP Common Stock (as hereafter defined), pursuant to the
terms of that certain Preferred Stock Agreement dated of even date herewith
between InterCAP and the holders of at least 95% of InterCAP Preferred Stock, a
copy of which is attached as EXHIBIT B to this Agreement (the "PREFERRED STOCK
AGREEMENT"); and

          (e) in connection with the Stockholders' Meeting, unanimously
recommend that the stockholders approve an amendment to InterCAP's certificate
of incorporation in the form contemplated by the Preferred Stock Agreement (the
"CHARTER AMENDMENT").

     SECTION 1.8  Preparation of S-4; Other Filings.  As promptly as practicable
                  ---------------------------------                             
after the date of this Agreement, Intergraph shall prepare and file with the
Securities and Exchange Commission ("SEC") the Form S-4.  Each of Intergraph and
InterCAP shall use its best efforts to respond to any comments of the SEC, to
have the Form S-4 declared effective under the Securities Act as promptly as
practicable after such filing, and to cause the Proxy Statement to be mailed to
the holders of InterCAP Stock (as defined in Section 2.1) at the earliest
practicable time, but in any event within two business days after the Form S-4
has been declared effective by the SEC.  As promptly as practicable after the
date of this Agreement, Intergraph and InterCAP shall properly prepare and file
any other filings required under the Securities Exchange Act of 1934, as amended
(the "EXCHANGE ACT"), the Securities Act or any other federal or state laws, and
Intergraph shall properly prepare and file any filings required under state
securities or "blue sky" laws, in each case relating to the Merger and the
transactions contemplated by this Agreement (collectively, the "OTHER FILINGS").
InterCAP shall promptly furnish Intergraph with all information concerning
InterCAP as may be reasonably required in connection with any action
contemplated by this Section 1.8.  Each party will notify the other party
promptly of the receipt of any comments from the SEC or its staff and of any
request by the SEC or its staff or any other government officials for amendments
or supplements to the Form S-4 or any Other Filing or for additional
information. Each party will supply the other party with copies of all
correspondence between such party or any of its representatives, on the one
hand, and the SEC, or its staff or any other government officials, on the other
hand, with respect to the Form S-4, the Merger or any Other Filing.  Each party
shall promptly provide the other party (or its counsel) with copies of all
filings made by such party with any governmental authority in connection with
this Agreement and the transactions contemplated hereby and thereby.  The Form
S-4 and the Other Filings shall comply in all material respects with all
applicable requirements of law.  Whenever any event occurs which should be set
forth in an amendment or supplement to the Form S-4 or any Other Filing, 
Intergraph or InterCAP, as the case may be, shall promptly 

                                       3
<PAGE>
 
inform the other party of such occurrence and cooperate in filing with
the SEC or its staff or any other government officials, and/or mailing to
stockholders of InterCAP, such amendment or supplement.

     SECTION 1.9  Closing.  Upon the terms and subject to the conditions hereof,
                  -------                                                       
as soon as practicable after the vote of the stockholders of InterCAP in favor
of the approval and adoption of this Agreement has been obtained, and the
satisfaction or waiver, if permissible, of the conditions set forth in Article
VII hereof, InterCAP, Intergraph Subsidiary and Intergraph shall execute and
deliver the Certificate of Merger, as described in Section 1.2, and the parties
hereto shall take all such other and further actions as may be required by law
to make the Merger effective.  Prior to the filing of the Certificate of Merger
pursuant to Section 1.2, a closing (the "CLOSING") will be held at such place as
the parties may agree for the purpose of confirming all of the foregoing.  The
date upon which the Closing takes place is sometimes referred to hereinafter as
the "CLOSING DATE".


                                  ARTICLE II.

                EFFECT OF THE MERGER ON THE CAPITAL STOCK OF THE
               CONSTITUENT CORPORATIONS; EXCHANGE OF CERTIFICATES

     SECTION 2.1  Total Consideration; Effect on Capital Stock.  In
                  --------------------------------------------     
consideration of the Merger, Intergraph will (i) issue to the holders of the
common and preferred shares of InterCAP stock (collectively, the "INTERCAP
STOCK"), shares of Intergraph common stock, par value $.10 per share
("INTERGRAPH COMMON STOCK"), (ii) pay cash in respect of fractional shares
pursuant to Section 2.2(c) hereof, and (iii) assume certain outstanding InterCAP
stock options as specified in Section 2.3 (collectively, the "MERGER
CONSIDERATION").  The aggregate number of shares of Intergraph Common Stock to
be issued to holders of InterCAP Stock in the Merger, exclusive of shares
issuable upon the exercise of Assumed Options under Section 2.3 (the "TOTAL
INTERGRAPH SHARE AMOUNT") shall be determined by (i) subtracting the Aggregate
Assumed Option Spread (as defined in Section 2.3(e)) from $7,500,000 (with the
result of such subtraction being referred to as the "CLOSING MERGER
CONSIDERATION"), and (ii) dividing the Closing Merger Consideration by the
average closing sale price of Intergraph Common Stock as reported by the NASDAQ
National Market System for the ten (10) days of trading immediately preceding
the fifth business day prior to the Closing Date (the "SHARE DETERMINATION
MARKET PRICE").  The Total Intergraph Share Amount shall be available for the
conversion and exchange of all outstanding shares of capital stock of InterCAP
and for all options (other than the Assumed Options to be assumed under Section
2.3), warrants, rights, calls, commitments or agreements of any character to
which InterCAP is a party or by which it is bound calling for the issuance of
shares of capital stock of InterCAP, or any securities convertible into or
exercisable or exchangeable for, or representing the right to purchase or
otherwise receive, directly or indirectly, any such capital stock, or other
arrangements to acquire, at any time or under any circumstance, capital stock of
InterCAP or any such other securities (the "FULLY DILUTED INTERCAP SHARES").

                                       4
<PAGE>
 
For purposes of the calculation of the exchange ratio for Intergraph Common
Stock under Section 2.1(c) hereof, it is assumed that the number of Fully
Diluted InterCAP Shares is as set forth in InterCAP's representations and
warranties in Section 3.3 hereof. At the Effective Time, subject and pursuant to
the terms and conditions of this Agreement, by virtue of the Merger and without
any action on the part of the Constituent Corporations or the holders of the
capital stock of the Constituent Corporations:

          (a) CAPITAL STOCK OF INTERGRAPH SUBSIDIARY.  Each issued and
outstanding share of the common stock, par value $.01 per share, of Intergraph
Subsidiary shall be converted into one share of common stock, par value $.01 per
share, of the Surviving Corporation.

          (b) CANCELLATION OF CERTAIN SHARES OF INTERCAP STOCK.  Each share of
InterCAP Stock that is (i) owned by InterCAP as treasury stock, (ii) authorized
but unissued, or (iii) owned by any subsidiary of InterCAP, shall be cancelled
and no Intergraph Common Stock or other consideration shall be delivered in
exchange therefor.  As used herein, a "subsidiary" of any corporation means
another corporation an amount of whose voting securities sufficient to elect at
least a majority of its Board of Directors is owned directly or indirectly by
such corporation.

          (c) EXCHANGE RATIOS.  Subject to Sections 2.1 and 2.2 of this
Agreement, shares of InterCAP Stock shall be exchanged and converted into shares
of Intergraph Common Stock on the following basis:

              (i) each share of InterCAP Series A Convertible Preferred Stock, 
$.01 par value per share ("INTERCAP SERIES A PREFERRED STOCK"), issued and
outstanding at the Effective Time (other than shares cancelled pursuant to
Section 2.1(b) and shares held by Dissenting Stockholders, if any), including
all accrued and unpaid dividends thereon, shall be exchanged and converted into
the right to receive a fraction of a share of Intergraph Common Stock having a
value (determined prior to the Closing Date using the Share Determination Market
Price) of $1.475000000 (the "SERIES A EXCHANGE RATIO");

              (ii) each share of (a) InterCAP common stock, $.01 par value per 
share ("INTERCAP COMMON STOCK"), (b) InterCAP Series B Convertible Preferred 
Stock, $.01 par value per share ("INTERCAP SERIES B PREFERRED STOCK"), if any,
and (c) InterCAP Series C Convertible Preferred Stock, $.01 par value per share
("INTERCAP SERIES C PREFERRED STOCK"), if any, issued and outstanding at the
Effective Time (other than shares cancelled pursuant to Section 2.1(b) and
shares held by Dissenting Stockholders, if any), including all accrued and
unpaid dividends thereon, shall be exchanged and converted into the right to
receive a fraction of a share of Intergraph Common Stock having a value
(determined prior to the Closing Date using the Share Determination Market
Price) of $.90975693 (the "NON-SERIES A EXCHANGE RATIO"); and

              (iii)  For purposes of this Agreement,

                                       5
<PAGE>
 
              (A) the Series A Exchange Ratio and the Non-Series A Exchange 
Ratio are referred to as the "EXCHANGE RATIOS";

              (B) all calculations under this Section 2.1(c) shall be rounded 
to the nearest one hundred millionth (.00000001).

Each share of Intergraph Common Stock to be issued upon conversion of shares of
InterCAP Stock in accordance with this Section 2.1(c) shall include the
corresponding percentage of a right (the "INTERGRAPH RIGHTS") to purchase
"Common Shares" pursuant to and as defined in the Rights Agreement dated August
25, 1993 by and between Intergraph and Harris Trust and Savings Bank, an
Illinois banking corporation (the "INTERGRAPH RIGHTS AGREEMENT").  Prior to the
Distribution Date (as defined in the Intergraph Rights Agreement), all
references in this Agreement to the Intergraph Common Stock to be received in
the Merger shall be deemed to include the Intergraph Rights.  For convenience of
reference, the shares of Intergraph Common Stock to be issued upon the exchange
and conversion of InterCAP Stock in accordance with this Section 2.1(c) are
sometimes hereinafter collectively referred to as the "INTERGRAPH SHARES".

          (d) SHARES OF DISSENTING STOCKHOLDERS.  Each issued and outstanding
share of InterCAP Stock held by any InterCAP stockholder who has not voted for
the Merger and who shall have delivered a written demand for payment of the fair
value of such InterCAP Stock within the time and in the manner provided in
Section 262 of the GCL ("DISSENTING STOCKHOLDERS"), if any, shall not be
exchanged and converted as described in Section 2.1(c) but shall become the
right to receive such consideration as may be determined to be due to such
Dissenting Stockholder pursuant to Section 262 of the GCL (the "DELAWARE
STATUTE"); provided, however, that each share of InterCAP Stock issued and
           --------  -------                                              
outstanding at the Effective Time and held by a Dissenting Stockholder who or
which shall, after the Effective Time, withdraw his or its demand for appraisal
or lose or fail to perfect his or its right of appraisal as provided in the
Delaware Statute shall be deemed, as of the Effective Time, to be exchanged and
converted into Intergraph Common Stock as provided in Section 2.1(c), without
interest.  After the Effective Time, as provided in the Delaware Statute, no
Dissenting Stockholder will be entitled to vote the shares of InterCAP Stock
which are the subject of such Dissenting Stockholder's demand for appraisal for
any purpose or be entitled to the payment of dividends or other distributions on
such shares.

          (e) ADJUSTMENTS FOR CAPITAL CHANGES.  If, prior to the Effective Time,
Intergraph recapitalizes through a subdivision of its outstanding shares into a
greater number of shares, or a combination of its outstanding shares into a
lesser number of shares, or reorganizes, reclassifies or otherwise changes its
outstanding shares into the same or a different number of shares or other
classes, or declares a dividend on its outstanding shares payable in shares of
its capital stock or securities convertible into shares of its capital stock (a
"STOCK ADJUSTMENT EVENT"), then the applicable Exchange Ratio for InterCAP Stock
will be adjusted appropriately so as to maintain the relative proportionate
interests of the holders of shares of InterCAP Stock and the holders of shares
of Intergraph Common Stock.

     SECTION 2.2  Escrow Deposit; Exchange of Certificates.
                  ---------------------------------------- 

          (a) ESCROW DEPOSIT.  Before the Effective Time of the Merger,
Intergraph and InterCAP shall appoint a mutually acceptable escrow agent (the
"ESCROW AGENT") to serve as such under the Escrow Agreement (as defined in
Section 2.2(b)).  At the Effective Time, Intergraph shall cause to be deposited
with the Escrow Agent a certificate or certificates on behalf of each of the
stockholders of InterCAP (the "STOCKHOLDERS"), other than Dissenting
Stockholders, and such Stockholders, by their approval of the Merger, shall be
deemed to have authorized and directed Intergraph to make such deposit on their
behalf, representing fifteen percent (15%) of the Intergraph Shares to be issued
to each such Stockholder rounded up to the nearest whole share of Intergraph
Common Stock (collectively, the "ESCROW SHARES").

          (b) PROCEDURE FOR EXCHANGE.  Before the Effective Time of the Merger,
Intergraph shall appoint its transfer agent or such other entity as it may
determine to act as exchange agent (the "EXCHANGE AGENT") in the Merger.  As
soon as practicable following the Closing, Intergraph shall make available to
the Exchange Agent the Intergraph Shares (exclusive of the Escrow Shares).  As
soon as practicable after the Closing, the Exchange Agent shall mail to each
holder of record of a certificate (an "OLD CERTIFICATE") representing InterCAP
Stock at the Effective Time, (i) a letter of transmittal (which shall specify
that delivery shall be effected, and risk of loss and title to the Old
Certificates shall pass, only upon delivery of the Old Certificates to the
Exchange Agent and shall be in form reasonably satisfactory to Intergraph), and
(ii) instructions for use in effecting the surrender of the Old Certificates in
exchange for certificates evidencing the Intergraph Shares.  Upon surrender to
the Exchange Agent of an Old Certificate for cancellation, accompanied by a duly
executed letter of transmittal, the holder of such Old Certificate shall be
entitled to receive in exchange therefor, one or more certificates representing
the number of Intergraph Shares (other than Escrow Shares) to which such holder
is entitled under Section 2.1 (the "NEW CERTIFICATES").  The Old Certificates so
surrendered shall be forthwith cancelled.  In the event any Old Certificates are
alleged to be lost, stolen or destroyed, the record owner of such Old
Certificates shall deliver to the Exchange Agent (i) an affidavit confirming
that such Old Certificates are lost, stolen or destroyed, (ii) a bond or other
indemnity agreement in form satisfactory to Intergraph sufficient to indemnify
Intergraph in respect of any subsequent claim relating to such lost, stolen or
destroyed certificates, and (iii) a duly executed letter of transmittal.  Upon
receipt of the items specified in clauses (i) - (iii) above, the Exchange Agent
shall issue and deliver New Certificates in respect thereof as if the lost,
stolen or destroyed Old Certificates had been surrendered in compliance with
this Agreement.  In the event of a transfer of ownership of shares of InterCAP
Stock which is not registered on the transfer records of InterCAP, a New
Certificate representing the proper number of shares of Intergraph Common Stock
may be issued to a transferee if the Old Certificate representing such InterCAP
Stock is presented to the Exchange Agent, accompanied by all documents required
to evidence and effect such transfer and by evidence that any applicable stock
or other transfer taxes have been paid.  Until surrendered as contemplated by
this Section 2.2, each Old Certificate shall be deemed, on and after the
Effective Time, to represent only the right to receive upon such surrender, New
Certificates representing the applicable Intergraph Shares (other than the
Escrow

                                       7
<PAGE>
 
Shares) as contemplated by Section 2.1(c), in all cases without interest.  All
Escrow Shares shall be held by, and distributed in accordance with, the terms
and provisions of an Escrow Agreement among InterCAP, Intergraph, the
Stockholders Committee (as hereafter defined) and the Escrow Agent in the form
of EXHIBIT C (the "ESCROW AGREEMENT").

          (c) FRACTIONAL SHARES.  No fractional shares of Intergraph Common
Stock will be issued in connection with the Merger, but in lieu thereof, each
holder of InterCAP Stock who would otherwise be entitled to receive a fraction
of a share of Intergraph Common Stock (after giving effect to the rounding
requirements of the last sentence of Section 2.2(a)) will receive from
Intergraph, at such time as such Stockholder shall receive a New Certificate
representing whole shares of Intergraph Common Stock as contemplated by Section
2.2(b), an amount of cash equal to the product of (i) the Share Determination
Market Price, multiplied by (ii) the fraction of a share of Intergraph Common
Stock otherwise issuable to such holder.  The fractional interests of each
Stockholder will be aggregated so that no Stockholder will receive cash in an
amount equal or greater than the value of the Share Determination Market Price
of one whole share of Intergraph Common Stock.

          (d) NO FURTHER OWNERSHIP RIGHTS IN INTERCAP STOCK.  All shares of
Intergraph Common Stock issued upon the surrender for exchange of shares of
InterCAP Stock in accordance with the terms of this Article II shall be deemed
to have been issued in full satisfaction of all rights pertaining to such shares
of InterCAP Stock.  If, after the Effective Time, any Old Certificate is
presented to the Surviving Corporation for any reason, such Old Certificate
shall be cancelled and exchanged as provided in this Article II.

          (e) NO LIABILITY.  Neither Intergraph, Intergraph Subsidiary nor
InterCAP shall be liable to any holder of shares of InterCAP Stock, or
Intergraph Common Stock, as the case may be, for shares (or dividends or
distributions with respect thereto) of Intergraph Common Stock to be issued in
exchange for InterCAP Stock pursuant to this Section 2.2, if, at the end of the
period from the Closing through the expiration of the time specified by
applicable Escheat Law (as hereafter defined), such shares are delivered to a
public official pursuant to any applicable abandoned property, escheat or
similar law ("ESCHEAT LAW").

     SECTION 2.3  Conversion of InterCAP Options.  At the Effective Time, each
                  ------------------------------                              
of InterCAP's then outstanding options (an "OPTION") shall be converted and
assumed as follows:

          (a) Each outstanding incentive stock option under InterCAP's 1989
Stock Option Plan (the "INTERCAP OPTION PLAN") which is listed on SCHEDULE 3.1
(collectively, the "ISO'S"), and each outstanding nonqualified stock option
awarded by InterCAP under InterCAP's 1994 Non-Qualified Stock Option Program
(the "INTERCAP OPTION PROGRAM") which is listed on SCHEDULE 3.1 (collectively,
the "NQSO'S"), shall, by virtue of the Merger and without any further action on
the part of the holder thereof, be assumed by Intergraph and automatically
converted into an option to purchase a number of shares of Intergraph Common
Stock determined by multiplying the number of shares of InterCAP Common Stock 
covered by 

                                       8
<PAGE>
 
the Option immediately prior to the Effective Time by the Option Conversion
Fraction, as defined below and rounded up to the nearest whole number of shares
(the "ADJUSTED INTERGRAPH SHARE AMOUNT"). The exercise price per share of
Intergraph Common Stock shall equal the exercise price in effect under such
Option immediately prior to the Effective Time divided by the Option Conversion
Fraction, and rounded up to the nearest whole cent (the "ADJUSTED INTERGRAPH
EXERCISE PRICE").

          (b) The options to purchase Intergraph Common Stock into which the
Options are converted pursuant to Section 2.3(a) shall contain the same status
as "incentive stock options" under Section 422 of the Code (but only if such
Options were theretofore incentive stock options under Section 422 of the Code),
and, except as disclosed on SCHEDULE 2.3, shall otherwise be on substantially
the same terms and conditions as the Option being assumed (including without
limitation, a requirement that the vesting of each ISO shall be accelerated by
virtue of the Merger and the vesting of each NQSO shall be as set forth in the
form of Non-Qualified Stock Option Agreement attached as EXHIBIT E hereto (the
"NQSO AGREEMENT")).  Following conversion and assumption by Intergraph, the
Options are referred to herein as "ASSUMED OPTIONS."

          (c) As used herein, the term "OPTION CONVERSION FRACTION" means a
fraction, the numerator of which is $.90975693 and the denominator of which is
the Share Determination Market Price.

          (d) Intergraph shall take all corporate action necessary to reserve
for, or otherwise permit the issuance of, a sufficient number of shares of
Intergraph Common Stock for delivery upon exercise of the Assumed Options in
accordance with this Section 2.3.  Prior to the Effective Time, Intergraph shall
file one or more registration statements on Form S-8 (the "FORM S-8") with
respect to the shares of Intergraph Common Stock subject to such Assumed
Options, and shall use its best efforts to maintain the effectiveness of such
registration statement as of the Effective Time and for so long as such Assumed
Options remain outstanding.

          (e) For purposes of this Agreement, the term "AGGREGATE ASSUMED OPTION
SPREAD" means an amount equal to $1,021,573.65.


                                  ARTICLE III.

                   REPRESENTATIONS AND WARRANTIES OF INTERCAP

     InterCAP represents, warrants and covenants to Intergraph and to Intergraph
Subsidiary as follows:

     SECTION 3.1  Organization and Qualification.  InterCAP is a corporation
                  ------------------------------                            
duly organized, validly existing and in good standing under the laws of the
State of Delaware, and has all requisite power and authority to own, lease, and 
operate its properties and assets, and to carry on 

                                       9

its business as is now being conducted.  InterCAP is duly qualified as a

     SECTION 3.3  Capitalization.
                  -------------- 

          (a) As of the date of this Agreement, the authorized capital stock of
InterCAP consists of 20,000,000 shares of InterCAP Common Stock, $.01 par value,
and 10,000,000 shares of InterCAP Preferred Stock, par value $.01 per share
("INTERCAP PREFERRED STOCK"), of which 2,911,478 shares of InterCAP Common
Stock, 927,326 shares of InterCAP Preferred Stock designated as InterCAP Series
A Convertible Preferred Stock, 1,716,387 shares of InterCAP Preferred Stock 
designated as InterCAP Series B Convertible Preferred Stock, and 953,442 shares 

                                      10
<PAGE>
 
of InterCAP Preferred Stock designated as InterCAP Series C Convertible
Preferred Stock are issued and outstanding. InterCAP previously reserved up to a
maximum of 2,500,000 shares of InterCAP Common Stock for issuance upon the
exercise of Options pursuant to the InterCAP Option Plan, of which (i) 1,173,376
have been exercised or have terminated or expired unexercised, (ii) 935,062 have
been granted and remain outstanding but unexercised as ISO's at exercise prices
ranging from $.10 to $.42 per share of InterCAP Common Stock with an aggregate
exercise price of $137,331.20, and (iii) 391,562 have been irrevocably retired
from such reservation and are no longer available for future grants or awards.
InterCAP has reserved up to a maximum of 391,562 shares of InterCAP Common Stock
for issuance upon exercise of Options pursuant to the InterCAP Option Program,
all of which Options have been or will be granted on terms set forth in the NQSO
Agreement, as disclosed on Schedule 2.3, to such persons, with respect to such
InterCAP Stock, and at such exercise prices as are listed on SCHEDULE 3.1 (and
an aggregate exercise price of $48,000.53). InterCAP has reserved 50,000 shares
of InterCAP Common Stock for issuance upon the exercise of warrants expiring in
December of 1996 and having an exercise price of $.25 per share of InterCAP
Common Stock (the "WARRANTS"). Pursuant to the Preferred Stock Agreement, such
Warrants will be exercised prior to the Effective Time, resulting in the
issuance of an additional 36,260 shares of InterCAP Common Stock. SCHEDULE 3.1
sets forth, with respect to each Option, the number of shares of InterCAP Common
Stock covered by such Option, the exercise price, the term and the holder of
such Option. Except as disclosed on SCHEDULE 2.3, each ISO has been awarded on
the terms set forth in the form of "InterCAP Graphics Systems, Inc. 1989
Employee Stock Option Agreement" attached hereto as EXHIBIT D, and each NQSO has
been awarded on the terms set forth in the NQSO Agreement. The ISO's have been
awarded under, and in substantial compliance with the terms of, the InterCAP
Option Plan, and the InterCAP Option Plan has been validly approved by the
requisite vote of the InterCAP Stockholders. As of the Effective Time, all
issued and outstanding shares of InterCAP Stock reflected on the amended
SCHEDULE 3.1 required to be delivered under Section 3.1 will be duly and validly
issued, fully paid and nonassessable. SCHEDULE 3.3 hereto provides a summary of
the capital structure of InterCAP as of the date of this Agreement, and except
for transactions expressly contemplated by the Preferred Stock Agreement, such
summary will accurately describe the capital structure of InterCAP at the
Effective Time. Except as disclosed on SCHEDULES 3.1 or 3.3, there are no
outstanding subscriptions, options, rights, warrants, convertible securities, or
other agreements, commitments, or obligations of InterCAP to issue any shares of
its capital stock of any class, except as contemplated by this Agreement, or to
sell, hypothecate, dispose of, or otherwise transfer shares or any other equity
interest in InterCAP.

          (b) The InterCAP Series A Preferred Stock has a liquidation preference
of $1.4750 per share, and is convertible into InterCAP Common Stock at a ratio
of 1.0 to  1.3329, and neither such liquidation preference nor conversion ratio
has been adjusted or modified since June 30, 1994, except to the extent the
effect of such adjustment or modification will be waived or postponed upon
execution of the Preferred Stock Agreement.  As of June 30, 1994, undeclared,
accrued but unpaid dividends on the InterCAP Series A Preferred Stock totaled
$.82 per share in the case of 339,068 shares and $.79 per share in the case of
the remaining 576,272 

                                      11
<PAGE>
 
shares of InterCAP Series A Preferred Stock (rounded to the nearest cent).  
Since June 30, 1994, undeclared, unpaid dividends on the InterCAP Series A
Preferred Stock have accrued and continue to accrue on a daily basis at an
annualized rate of 10% ($.1475 per share) (collectively, the "ACCRUED SERIES A
DIVIDENDS"). By virtue of the Preferred Stock Agreement and the Charter
Amendment, the liquidation preference for the InterCAP Series A Preferred Stock
will be fixed at $1.4750 per share during the period specified in the Preferred
Stock Agreement and as of the Effective Time, and such liquidation preference
will not have been increased to reflect any portion of the Accrued Series A
Dividends. The InterCAP Series B Preferred Stock has a liquidation preference of
$.5978 per share. After October 1, 1994, such liquidation preference will be
$.5978 plus one-half of all accrued and unpaid dividends (whether or not
declared) from January 1, 1993 (the "DIVIDEND ADJUSTMENT AMOUNT"), which
Dividend Adjustment Amount will be approximately $.04 per share as of October 1,
1994, and will accrue at a rate of $.025 per year thereafter. The InterCAP
Series B Preferred Stock is convertible into InterCAP Common Stock at a ratio of
1.0 to 1.0. Neither the liquidation preference of the InterCAP Series B
Preferred Stock nor its conversion ratio has been adjusted or modified since
June 30, 1994, other than increases in such liquidation preference on a daily
basis at an annualized rate of 5% ($.025 per share) in respect to additional
undeclared, accrued but unpaid dividends. The InterCAP Series C Preferred Stock
has a liquidation preference of $.65552 per share plus accrued and unpaid
dividends, whether or not declared (which, as of June 30, 1994, were $.17 per
share, rounded to the nearest cent), and is convertible into InterCAP Common
Stock at a ratio of 1.0 to 1.0, and neither such liquidation preference nor such
conversion ratio has been adjusted or modified since June 30, 1994, other than
increases in such liquidation preference on a daily basis at an annualized rate
of 10% ($.065552 per share) in respect of additional undeclared, accrued but
unpaid dividends.

          (c) All options to acquire any equity interest in InterCAP, other than
the ISO's and NQSO's, and all warrants to purchase InterCAP Common Stock or
InterCAP Preferred Stock, including all Warrants, have been exercised or have
expired, or will be exercised or will expire prior to Closing.

          (d) Except as described on SCHEDULE 3.3, InterCAP is not obligated
(either by virtue of its certificate of incorporation or otherwise) under or
with respect to any put, call, redemption right, repurchase obligation, right of
first refusal, buy-sell arrangement or other contractual commitment of InterCAP
to repurchase or redeem any InterCAP Stock (collectively a "REPURCHASE
OBLIGATION").  As of the date of this Agreement, no Repurchase Obligation is
currently in effect that requires InterCAP to redeem or repurchase any InterCAP
Stock, and as of the Effective Time, no Repurchase Obligation will obligate
InterCAP to redeem or repurchase any InterCAP Stock.

     SECTION 3.4  Authority.  This Agreement has been duly authorized by the
                  ---------

acceleration or imposition would have a Material Adverse Effect; or (iii) will

and every one of its obligations hereunder have been obtained or will be

     SECTION 3.10  Environmental Matters.
                   --------------------- 

          (a) InterCAP has obtained all the necessary permits under, has
complied with and is currently in full compliance with, all restrictions,
limitations, conditions, standards, prohibitions, and other requirements under,
all applicable laws relating to pollution, waste disposal, or protection of the
environment, including, without limitation, laws relating to emissions,
discharges, releases or threatened releases of pollutants, contaminants,
chemicals, or industrial, toxic, or hazardous substances or wastes, into the

water, land surface, or subsurface strata) or otherwise relating to the
manufacture, processing, distribution, use, treatment, storage, disposal,
transport or handling of pollutants, contaminants, chemicals, or industrial,
toxic or hazardous substances or wastes or other Environmental Laws (as defined
in Section 10.9(b)).  InterCAP has not released or disposed of, or arranged or
provided for disposal of, any Polluting Substances in a manner that violates or
contravenes any applicable Environmental Law.

          (b) InterCAP's leasehold interest in its office space is, to the best
of InterCAP's knowledge, free of any and all Polluting Substances (as defined in
Section 10.9(c)) or other type of contamination that are matters of
environmental concern, and InterCAP owns no interest in real estate other than
such leasehold interest.

          (c) There is no civil, criminal, or administrative action, suit,
demand, claim, hearing, notice of violation, investigation, proceeding, notice
or demand letter pending or, to the knowledge of InterCAP, threatened against
InterCAP relating in any way to the Environmental

Laws or any rule, regulation, ordinance, interpretation, code, plan, order, 
decree, judgment, injunction, notice or demand letter issued, entered, 
promulgated, or approved thereunder.

     SECTION 3.11  Intellectual Property.
                   --------------------- 

          (a) SCHEDULE 3.11 of this Agreement lists (i) by product or program
name, every computer software product and program which is solely and
exclusively owned by InterCAP, and which is material to the business of InterCAP
as presently constituted, as well as all documentation owned by InterCAP which
is shipped to end users (collectively, "INTERCAP PRODUCTS"); (ii) by product
name or the identity of the sole or joint owner, every computer software
product, program, or other intellectual property which is separately owned by,
or jointly owned with, a third party (collectively, "ISD'S"), and which is
material to the business of InterCAP ("ISD PROPERTY"); (iii) each and every
registered and unregistered trademark and trademark application, trade name,
registered patent and patent application, and copyright registration and
copyright registration application, which is solely or jointly owned or, in the
case of applications, filed by or on behalf of InterCAP (collectively, the
"INTELLECTUAL PROPERTY RIGHTS").

          (i) The InterCAP Products and the ISD Property (collectively, the
"SOFTWARE PRODUCTS") constitute all of the computer software code currently
necessary for InterCAP to conduct the material aspects of its business as
presently constituted (including but not limited to supporting customers,
modifying and enhancing the InterCAP Products, developing software to meet
product commitments to existing customers and customer prospects, and developing
software to meet existing product development plans) and, to the best of
InterCAP's knowledge and belief, meet InterCAP's current business plans;
provided, however, that to the extent the Software Products may not be
- --------  -------                                                     
sufficient to meet InterCAP's current business or product development plans,
InterCAP does not have reason to believe that InterCAP would be incapable of, or
prohibited from, independently creating or obtaining such computer software code
as may be necessary to carry out such plans.

          (ii) InterCAP is the sole and exclusive owner of all right, title, and
interest in and to the InterCAP Products, and owns licenses or other valid
rights to use any intellectual property upon which the InterCAP Products are
based or from which the InterCAP Products are derived, including but not limited
to the right to use, reproduce, modify, and distribute the InterCAP Products, as
well as the right to grant licenses to ISD's and pursue infringement actions.
To the best of InterCAP's knowledge and belief, InterCAP's exercise and full
enjoyment of the rights and privileges appurtenant to such exclusive ownership
will not infringe upon the intellectual property rights of others, and no person
or other entity has made, or to the best of InterCAP's knowledge, threatened to
make any claim that the exercise and full enjoyment of such rights will
constitute an infringement of the intellectual property rights of such other
person or entity.

                                      17
<PAGE>
 
          (iii)   InterCAP has valid and sufficient rights in the ISD Property
to permit InterCAP to conduct its business and, to the best of InterCAP's
knowledge and belief, to meet InterCAP's current business plans.  To the best 
of InterCAP's knowledge and belief, none of the ISD's currently intend, or 
during the past year have threatened, to terminate or revoke such rights.

          (b) Except as disclosed in SCHEDULE 3.11 to this Agreement, the
InterCAP Products are free and clear of liens, mortgages, and other
encumbrances, and InterCAP has not released, disclosed, or created or suffered
the creation of a contingent or existing obligation to release, disclose,
transfer, deliver, or license (i) the source codes for any of the InterCAP
Products, or (ii) any trade secrets or other confidential or proprietary
information relating to the InterCAP Products (including, without limitation,
information relating to or describing source code architecture, subroutine
calls, algorithms (if any), or programmers' notes or similar documentation),
unless such release, disclosure, transfer, delivery, or license was accompanied
by a non-disclosure agreement prohibiting the recipient from using or disclosing
such trade secrets or information.  Neither the execution and delivery of this
Agreement or any other agreement referred to herein, nor the consummation of the
transactions contemplated hereby, will cause or result in the release or
disclosure of any of the foregoing.

          (c) Except as disclosed in SCHEDULE 3.11, each and every current and
former employee and consultant of InterCAP hired or retained by InterCAP since
January 1, 1988 who had access to InterCAP's trade secrets and proprietary and
confidential information has entered into an employment, non-disclosure, or
consulting agreement (collectively, "Protective Agreements") with InterCAP
containing provisions (i) assigning all of such employee's or consultant's
right, title, and interest, if any, in and to the InterCAP Products to InterCAP,
or designating the product of any programming services performed for InterCAP to
be Works-Made-For-Hire, as that term is defined in Section 101 of the Copyright
Act of 1976, and (ii) prohibiting the disclosure of InterCAP's trade secrets and
proprietary and confidential information by such employee or consultant.  To the
best of InterCAP's knowledge and belief, there have been no breaches of any of
the Protective Agreements, or any other unauthorized release, disclosure, use,
or appropriation of any InterCAP trade secrets or other confidential or
proprietary information of InterCAP.

          (d) InterCAP has no copyright registrations, trademark registrations,
or patents.

          (e) Except as disclosed in SCHEDULE 3.11 to this Agreement, InterCAP
is under no existing or contingent obligation to compensate any other person or

     SECTION 3.12  Employee Benefit Plans.
                   ---------------------- 
 
          (a) PLANS AND RELATED DOCUMENTS.  InterCAP does not have or purport to
have, and does not contribute to, any pension, profit-sharing, option, severance
compensation or incentive plan or arrangement, or any other type of Employee
Benefit Plan (as defined in Section 3(3) of the Employee Retirement Income
Security Act of 1974 ("ERISA")) ("EMPLOYEE PLAN"), or have any obligation to, or
customary arrangement with, employees for bonuses, incentive compensation,
vacations, severance pay, insurance or other benefits, except as set forth in
SCHEDULE 3.12 of this Agreement (other than statutory protections afforded to
employees under non-U.S. law).  A complete and accurate summary of each Employee
Plan and a complete and accurate copy of each document prepared in connection
with such Employee Plan has been furnished to Intergraph.
 
          (b) ABSENCE OF CERTAIN TYPES OF PLANS.  None of the Employee Plans is
a multi-employer plan (within the meaning of Section 3(37) or 4001(a)(3) of
ERISA) or a single employer pension plan (within the meaning of Section
4001(a)(15) of ERISA) for which InterCAP could incur liability under Section
4063 or 4064 of ERISA.  Except as set forth in SCHEDULE 3.12, none of the
Employee Plans is a severance plan within the meaning of the provisions of ERISA
applicable to severance plans. Except as set forth in SCHEDULE 3.12, none of the
Employee Plans obligate InterCAP to pay separation, severance, termination, or
similar-type benefits solely as a result of any transaction contemplated by this
Agreement or as a result of a "change in control" with respect to InterCAP,
within the meaning of such terms under Section 280G of the Code. None of the
Employee Plans provides for or promises retiree medical or life insurance
benefits to any current or former employee, officer, or director of InterCAP.
 
          (c) COMPLIANCE WITH APPLICABLE LAW.  Each Employee Plan has been
operated in all material respects in accordance with the requirements of all
applicable laws, including, without limitation, ERISA and the Code.  InterCAP
has timely filed all reports or other materials required to be filed under ERISA
in connection with the Employee Plans.  InterCAP has performed all obligations
required to be performed by it or under, is not in any respect in default under
or in violation of, and has no knowledge of any default or violation by any
party to, any Employee Plan.  No legal action, suit, or claim is pending or
threatened with respect to any Employee Plan (other than claims for benefits in
the ordinary course) and, to InterCAP's knowledge, no fact or event exists that
could give rise to any such action, suit, or claim. The Internal Revenue Service
has issued a favorable determination letter with respect to the qualification of
each Employee Plan which is intended to be qualified and with respect to each
trust established in connection with any Employee Plan which is intended to be
exempt from federal income taxation under Section 501(a) of the Code, except in
the case of the InterCAP Graphics Systems, Inc. 401(k) Profit Sharing Plan and
Trust (the "401(k) PLAN"), which has been operated since inception pursuant to
standardized prototype plan forms which have received favorable determination
letters from the Internal Revenue Service.

                                      19
<PAGE>
 
          (d) PLAN CONTRIBUTIONS AND FUNDING.  All contributions, premiums, or
payments required to be made with respect to any Employee Plan have been made on
or before their due dates.  All such contributions have been fully deducted for
income tax purposes, no such deduction has been challenged or disallowed by any
governmental entity, and no fact or event exists which could give rise to any
such challenge or disallowance. As of the Closing, no Employee Plan which is
subject to Title IV of ERISA will have an "UNFUNDED BENEFIT LIABILITY" (within
the meaning of Section 4001(a)(18) of ERISA). No funded plan, arrangement, or
policy covering employees, officers, or directors of InterCAP or its
subsidiaries employed outside of the United States has any unfunded liabilities
that, as of the balance sheets provided pursuant to Section 3.6 of this
Agreement, were not fully reflected in such balance sheets.

          (a) There are no labor or employment controversies pending or, to the
knowledge of InterCAP, threatened between InterCAP or its subsidiaries and any
of their employees;
 
          (b) InterCAP is not now, and has never been, a party to any collective
bargaining agreement or other labor union contract applicable to persons
employed by InterCAP or its subsidiaries, nor are there any activities or
proceedings of any labor union to organize any such employees; and
 
          (c) There are no unfair labor practice complaints pending against
InterCAP before the National Labor Relations Board or any current union
representation questions involving employees of InterCAP or its subsidiaries.
 
     SECTION 3.15  Compliance with Laws.  InterCAP and its subsidiaries have
                   --------------------                                     
been and continue to be in compliance with all, and are not in violation of any,
applicable laws, regulations, or administrative orders of any county, state,
municipality, or of any subdivision thereof to which their business, properties,
or any part thereof is subject, the violation of which, or the non-compliance
with which, would have a Material Adverse Effect.
 
     SECTION 3.16  Litigation and Customer Relations.  No suit, action,
                   ---------------------------------                   
arbitration, administrative proceeding, or governmental investigation is pending
or, to InterCAP's knowledge, threatened by, against or affecting InterCAP or its
business, properties, rights, assets, or financial condition.  InterCAP is not
in violation of any order, writ, injunction, or decree to which it is subject of
any federal, state, local, or foreign court, department, agency, or
instrumentality.  InterCAP has furnished Intergraph with copies of all written
customer complaints made against InterCAP in connection with the performance or
lack thereof of its software since July 1, 1992, 
 
                                      20
 
<PAGE>
 
and none of InterCAP's software has been rejected or returned as a result of
unacceptable performance or functionality. To the best of InterCAP's knowledge,
no material portion of InterCAP's renewal customer base has materially reduced
or terminated, or, to the knowledge of InterCAP intends to materially reduce or
terminate, the amount of its renewal business with InterCAP. InterCAP has
furnished to Intergraph true and correct copies of InterCAP's standard form of
end-user license agreement, distributor agreement and renewal agreement
(collectively, the "SPECIFIED PRODUCT AGREEMENTS"), and except as disclosed on
SCHEDULE 3.17, all of InterCAP's relationships with end-users or distributors
conform to the material terms of the Specified Product Agreements and contain no
material terms in addition to those contained in the Specified Product
Agreements. SCHEDULE 3.17 lists all distributors or others having currently
effective rights to sell, license, market or distribute any of the InterCAP
Products. Except as disclosed on SCHEDULE 3.16, to the best of InterCAP's
knowledge, none of its end-user licensees or renewal licensees has expressed to
InterCAP an intention to reduce their license commitments with InterCAP.
 
     SECTION 3.17  Assets and Material Contracts; Insurance.  InterCAP has good
                   ----------------------------------------

Intellectual Property Rights, free and clear of any and all liens, claims, and
encumbrances, except as described on the Financial Statements or in any of the
Schedules to this Agreement.  InterCAP has sufficient rights to use the assets
and properties currently employed in the conduct of its business.  InterCAP
maintains adequate insurance coverage on its assets and properties in accordance
with customary industry practice.  SCHEDULE 3.17 lists and briefly describes all
policies of title, asset, fire, hazard, casualty, liability, life, workers'
compensation and other forms of insurance held by InterCAP.  Except as described
on SCHEDULE 3.17, InterCAP has no material contracts to which it is a party or
by which it is bound.  All contracts to which InterCAP is a party (including,
without limitation, any debt instrument or agreement) are valid and legally
binding and are in full force and effect.  To InterCAP's knowledge, there are no
defaults thereunder by any party thereto, and there are no conditions which,
with notice, the lapse of time, or both, would constitute a default by any party
thereunder. To the best of InterCAP's knowledge, SCHEDULE 3.17 also lists all
written or oral contracts, agreements and other instruments not made in the
ordinary course of business to which InterCAP is a party, or made in the
ordinary course of business and referred to in clauses (i) through (xiv) of this

In the event this Agreement is terminated pursuant to the provisions of Article

copies of such material to the extent necessary to defend (and solely for the
purpose of defending) its interests in any then pending or threatened dispute
between Intergraph and InterCAP concerning or relating to this Agreement.

     SECTION 6.2  Objections of Stockholders.  InterCAP will promptly advise
                  --------------------------

Intergraph and InterCAP by this Section 6.6 shall survive for one (1) year from
the date this Agreement terminates.  Subject to written advice of counsel with
respect to legal requirements relating to public disclosure of matters related
to the subject matter of this Agreement, the timing and content of any
announcements, press releases or other public statements concerning the proposal
contained herein will occur upon, and be determined by, the mutual consent of
Intergraph and InterCAP.  Intergraph shall request confidential treatment of the
schedules to this Agreement in connection with the filing of the Form S-4 and,
if applicable, the Forms S-8.

     SECTION 6.7  Employee Matters.  Intergraph presently intends that, after

employees of InterCAP immediately prior to the Effective Time shall not be
generally reduced as part of any Intergraph-wide reduction of employee
compensation, and (ii) the employees of InterCAP immediately prior to the

the business conditions, cost structure, and results of operations of InterCAP.

     SECTION 6.8  Expenses.  Except as set forth in Section 8.3, the parties
                  --------

Directors determines, in good faith, to pursue or accept a bona fide proposal or
offer from any Third Party concerning any merger, sale of assets, sale of
additional securities or any similar transaction, and certifies in writing to
Intergraph that (i) in the judgment of the Board of Directors such proposal or
offer is more favorable to InterCAP and the Stockholders than the Merger, and
(ii) the Board of Directors has determined, with the written advice of counsel,
that it must accept or pursue such proposal or offer in the exercise of its
fiduciary duties (any such offer or proposal is referred to as the "SUPERIOR
OFFER").

     SECTION 8.2  Effect of Termination.  In the event of the termination and
                  ---------------------                                      
abandonment of this Agreement pursuant to Section 8.1 hereof, this Agreement
shall forthwith become void and have no effect, without any liability on the
part of any party or its directors, officers or stockholders, other than the
provisions of Sections 6.6, 8.2, 8.3, 8.4 and 9.3.

     SECTION 8.3  Reimbursement of Expenses.  Provided that neither Intergraph
                  -------------------------                                   
or Intergraph Subsidiary is then in material breach of this Agreement, if this
Agreement is terminated by Intergraph following any intentional breach by
InterCAP of its covenants contained in Article IV of this Agreement, or any
intentional or reckless material misstatement or omission by InterCAP contained
in the representations in Article III of this Agreement, then in any such case,
InterCAP shall reimburse Intergraph (not later than three business days after
submission of a statement therefor) for all reasonable, actual documented out-
of-pocket fees or expenses (including but not limited to reasonable fees and
expenses of counsel, accounting fees, travel expenses, registration or filing
fees and the like) actually incurred in good faith by Intergraph or on its
behalf in connection with the proposed Merger or the negotiation, structuring,
evaluation or consummation of the transactions contemplated by this Agreement
(collectively, the "Designated Expenses").

     SECTION 8.4  Termination Fee.  Provided that neither Intergraph nor
                  ---------------                                       
Intergraph Subsidiary is then in material breach of this Agreement and that
Intergraph and Intergraph Subsidiary have satisfied the conditions of Section
7.1 (the satisfaction or performance of which are in the exclusive control of
Intergraph) and Section 7.3, if this Agreement is terminated (i) by InterCAP
pursuant to Section 8.1(f), (ii) by Intergraph as a result of the withdrawal or
material modification by the InterCAP Board of Directors of its recommendation
to the Stockholders with respect to the Merger (but only if such withdrawal
arises out of, relates to or follows any inquiry, contact or proposal to
InterCAP from a Third Party concerning any Superior Offer or other proposed
merger, sale of assets, sale of additional securities or similar transaction),
or (iii) by either party and any Superior Offer is approved by the requisite
vote of the holders of InterCAP Stock within 180 days of such termination if
such Superior Offer or the reasonable possibility of such Superior Offer was
known to InterCAP or its directors at the time this Agreement was 

                                      37
<PAGE>
 
terminated, then in any such case, InterCAP shall pay to Intergraph, at
Intergraph's election, an amount (the "Termination Fee") equal to the greater of
(i) the Designated Expenses plus an amount equal to the fully allocated,
reasonable documented cost of time (consisting of salary and benefits) actually
expended by Intergraph officers and employees in investigating, negotiating, and
taking steps necessary to consummate, the transactions contemplated by this
Agreement, but in no event to exceed $300,000 in the aggregate, (ii) $200,000 in
cash, or (iii) 10% of the excess over $7,500,000 of the total consideration
(whether in the form of cash, securities or other property, or assumption of
options or warrants) to be paid to InterCAP or its security holders in
connection with the Superior Offer. The applicable Termination Fee shall be paid
to Intergraph within 10 days of termination unless the amount specified in
clause (iii) is selected by Intergraph, in which case such amount shall be
payable upon consummation of the transaction contemplated by the Superior Offer.

     SECTION 8.5  Amendment.  To the extent permitted by applicable law, this
                  ---------                                                  
Agreement may be amended by action taken by or on behalf of the Boards of
Directors of Intergraph and InterCAP at any time before or after adoption of
this Agreement (but prior to the Effective Time), by the stockholders of
InterCAP; provided, however, that after any submission of this Agreement to such
          -----------------                                                     
stockholders for approval, no amendment shall be made which reduces the
applicable Merger Consideration or which materially and adversely affects the
rights of InterCAP's Stockholders hereunder without the approval of such
Stockholders.  This Agreement may not be amended except by an instrument in
writing signed on behalf of all the parties.

     SECTION 8.6  Extension; Waiver.  At any time prior to the Effective Time,
                  -----------------                                           
the parties may (i) extend the time for the performance of any of the
obligations or other acts of the other parties hereto, (ii) waive any
inaccuracies in the representations and warranties contained herein or in any
document, certificate or writing delivered pursuant hereto, or (iii) waive
compliance with any of the agreements or conditions contained herein.  Any
agreement on the part of any party to any such extension or waiver shall be

party.

                      SURVIVAL; INDEMNIFICATION; REMEDIES

     SECTION 9.1  Survival of Representations and Warranties.  All
                  ------------------------------------------      
representations, warranties, covenants and agreements of InterCAP contained in
this Agreement or in any instrument delivered pursuant to this Agreement or at
Closing shall survive the Closing to the extent specified in Section 9.2(d),
notwithstanding any investigation, audit or inspection at any time made by or on
behalf of Intergraph.  All statements contained in any certificate or other
instrument executed and delivered by InterCAP or its authorized officers or
representatives in accordance with this Agreement shall be deemed
representations by InterCAP.  All representations, warranties, covenants and
agreements of Intergraph shall terminate at the 

                                      38
<PAGE>
 
Effective Time and be of no further force and effect, and Intergraph shall have
no liability with respect thereto; provided, however, that for the benefit of
                                   -----------------
InterCAP and its Stockholders the covenants and agreements contained in Sections
2.3(d), 6.6, 6.7 and 9.2 of this Agreement shall survive the Closing.

     SECTION 9.2  Indemnification.
                  --------------- 

          (a) Subject to Section 9.2(e), the Stockholders, jointly and
severally, shall indemnify the Indemnified Persons for, and hold each of them
harmless from and against, any and all Losses arising from or in connection with
any Event of Indemnification, up to that amount constituting the Escrow Fund (as
defined in the Escrow Agreement), which indemnification pursuant to this Section
9.2(a) shall be effected solely in accordance with the terms and provisions of
the Escrow Agreement and shall be subject to the qualifications and limitations
set forth therein. In connection therewith, the Stockholders shall have no
liability to the Indemnified Persons in respect of Losses arising from or in
connection with any Event of Indemnification over and above the amounts from
time to time representing their respective interests in the Escrow Fund; and the
Indemnified Persons, and each of them, shall look for indemnification in respect
of any such claim under this Section 9.2(a) solely to the Escrow Fund in
accordance with the terms and provisions of the Escrow Agreement (it being
understood that nothing contained in this Section 9.2(a) shall in any way limit,
impair, modify or otherwise affect the rights of the Indemnified Persons,
including rights available under the Securities Act or the Exchange Act (A) to
bring any claim, demand, suit or cause of action otherwise available to the
Indemnified Persons based upon an allegation or allegations that InterCAP or the
Stockholders, or any of them, had an intent to defraud or made a willful
misrepresentation or willful omission of a material fact in connection with this
Agreement or any related agreements and the transactions contemplated hereby or
thereby or (B) to enforce any judgment of a court of competent jurisdiction or
decision of an arbitrator which finds or determines that InterCAP or the
Stockholders, or any of them, had an intent to defraud or made a willful
misrepresentation or omission of a material fact in connection with this
Agreement and the transactions contemplated hereby or thereby).

          (b) No claim shall be brought under Section 9.2(a) hereof unless the
Indemnified Persons, or any of them, at any time prior to the applicable
Survival Date, give the Stockholders' Committee (a) written notice of the
existence of any such claim, specifying the nature and basis of such claim and
the amount thereof, to the extent known or (b) written notice pursuant to
Section 9.2(d) of any third party claim, the existence of which might give rise
to such a claim.  Upon the giving of such written notice as aforesaid, the
Indemnified Persons, or any of them, shall have the right to commence
appropriate proceedings subsequent to the Survival Date for the enforcement of
their rights under Section 9.2(a).

          (c) The obligations and liabilities of a Stockholder with respect to
Losses resulting from the assertion of liability by third parties (each, a
"THIRD PARTY CLAIM") shall be subject to the following terms and conditions:

                                      39
<PAGE>
 
              (i) The Indemnified Persons shall promptly (and, in any event, 
     within ten (10) business days) give written notice to the Stockholders'
     Committee of any Third Party Claim which might give rise to any loss by the
     Indemnified Persons, stating the nature and basis of such Third Party
     Claim, and the amount thereof to the extent known. Such notice shall be
     accompanied by copies of all relevant documentation with respect to such
     Third Party Claim, including, without limitation, any summons, complaint or
     other pleading which may have been served, any written demand or any other
     document or instrument.
 
              (ii) The Indemnified Persons shall assume the defense of any Third
     Party Claims with counsel of their own choosing, which counsel shall be
     reasonably satisfactory to the Stockholders' Committee, and shall act
     reasonably and in accordance with their good faith business judgment in
     handling such Third Party Claims and shall not effect any settlement
     without the consent of the Stockholders' Committee, which consent shall not
     unreasonably be withheld or delayed. The Stockholders' Committee (and the
     Stockholders) and the Indemnified Persons shall make available to each
     other and their counsel and accountants all books and records and
     information relating to any Third Party Claims, keep each other fully
     apprised as to the details and progress of all proceedings relating thereto
     and render to each other such assistance as may be reasonably required to
     ensure the proper and adequate defense of any and all Third Party Claims.
 
          (d) Subject to the further provisions of this Section 9.2(d), the
representations and warranties of Intergraph and Intergraph Subsidiary shall be
deemed to be a condition to the Merger and shall not survive beyond the
Effective Time, and the representations and warranties made by InterCAP in
Article III hereof shall survive the Effective Time until the ninetieth (90th)
day after the Closing Date.  The representations and warranties made by the
parties hereto to counsel in connection with the opinions to be delivered (a)
pursuant to Article VII hereof at the Closing or (b) in connection with the
preparation of the registration statement on Forms S-4 and S-8 for the
Intergraph Common Stock shall survive the Effective Time; provided, however,
                                                          --------  ------- 
that such representations and warranties shall only be deemed to speak as of the
later of the date such representations and warranties were made or the Closing
Date.  For convenience of reference, the date upon which any representation and
warranty contained herein shall terminate is referred to herein as the "SURVIVAL
DATE".  Anything contained herein to the contrary notwithstanding, the
representations and warranties of InterCAP contained in this Agreement (i) are
being given by InterCAP on behalf of the Stockholders and for the purpose of
binding the Stockholders to the terms and provisions of this Section 9.2 and the
Escrow Agreement, and as an inducement to Intergraph and Intergraph Subsidiary
to enter into this Agreement and to approve the Merger (and InterCAP
acknowledges that Intergraph and Intergraph Subsidiary have expressly relied
thereon) and (ii) are solely for the benefit of the Indemnified Persons and each
of them.  Accordingly, no third party (including, without limitation, the
Stockholders) or any other holder of InterCAP Common Stock or anyone acting on
behalf of any thereof) other than the Indemnified Persons, and each of them,
shall be a third party or other beneficiary of such representations and
warranties and  no such third party shall have any rights of contribution
against InterCAP or the

Surviving Corporation with respect to such representations or warranties or any 
matter subject to or resulting in indemnification under this Section 9.2 or 
otherwise.

          (e) Anything to the contrary contained in Section 9.2 notwithstanding:

              (i)      The Stockholders shall not be obligated to indemnify the
     Indemnified Persons pursuant to this Section 9.2 with respect to any Losses
     until the aggregate amount of such Losses exceeds $150,000 (the "BASKET
     AMOUNT"), whereupon the Stockholders shall be obligated to indemnify the 
     Indemnified Persons for all Losses in excess of the Basket Amount (up to 
     their respective pro rata interest in the Escrow Fund as provided below 
                      --- ----
     in Section 9.2(e)(ii)).

              (ii)     The maximum aggregate liability of each Stockholder for
     indemnification under this Section 9.2 shall not exceed its or their 
     pro rata share of the aggregate amount of the Escrow Fund, determined on 
     --- ----
     the basis of the proportion which the number of Escrow Shares contributed
     into escrow by or on behalf of such Stockholder pursuant to Section 2.2(a)
     hereof bears to the total number of Escrow Shares contributed into escrow
     by or on behalf of all Stockholders pursuant to Section 2.2(a) hereof.

          (f) (i)      Upon approval of the Merger, the Stockholders shall be
deemed, for themselves and their personal representatives and other successors,
to have constituted and appointed, effective from and after the Effective Time,
a committee of three persons initially to consist of Joy E. Binford, A.G.W.
Biddle, III, and John C. Gebhardt, as their agents and attorneys-in-fact (the
"STOCKHOLDERS' COMMITTEE") to take all action required or permitted under this
Agreement and the Escrow Agreement (including, without limitation, the execution
and delivery of the Escrow Agreement on behalf of the Stockholders, the giving
and receiving of all notices and consents and the execution and delivery of all
documents, including any amendments of any non-material term or provision hereof
or the Escrow Agreement, and the execution and delivery of any agreements and
releases in connection with the settlement of any dispute or claim under Section
9.2 hereof or the Escrow Agreement).  The vote of a majority of the
Stockholders' Committee shall be required to take any action on behalf of the
Stockholders pursuant to the authority granted to them under this Section
9.2(f).

              (ii)     In the event of the death, physical or mental incapacity
or resignation of any of the members of any of the Stockholders' Committee or a
vacancy thereon for any other reason, the remaining members of the Stockholders'
Committee shall promptly appoint a further substitute or substitutes and shall
advise Intergraph thereof. As between the Stockholders' Committee and the
Stockholders, the members of the Stockholders' Committee shall not be liable
for, and shall be indemnified by the Stockholders or provided with insurance
against, any good faith error of judgment on their part or any other act done or
omitted by them in good faith in connection with their duties as members of such
Committee, except for gross negligence or willful misconduct. The Stockholders'
Committee may consult with professional advisors of its choice. The
Stockholders' Committee shall not be responsible for the genuineness

                                      41
<PAGE>
 
or validity of any document and shall have no liability for acting in accordance
with any written instructions given to them and believed by them to be signed by
the proper parties. The reasonable expenses incurred by the members of the
Stockholders' Committee in performing their duties (including fees and expenses
of professional advisors) and any indemnification to be provided to the
Stockholders' Committee, up to a maximum of $5000, shall be borne by the
Surviving Corporation.

     SECTION 9.3   Remedies.  In the event InterCAP breaches or wrongfully
                   --------                                               
terminates this Agreement or the additional agreements contemplated thereby,
Intergraph may, (i) terminate this Agreement or such other agreements and shall
have no further obligation to InterCAP thereunder, or (ii) require specific
performance of InterCAP's obligations under this Agreement or such other
agreements(including without limitation, InterCAP's obligations under Articles
VIII and IX), or seek actual damages arising from such breach or wrongful
termination in lieu of such specific performance.  In the event Intergraph
breaches or wrongfully terminates this agreement or the additional agreements
contemplated thereby, InterCAP may (i) terminate this Agreement or such other
agreements and shall have no further obligation to Intergraph thereunder, or
(ii) require specific performance of Intergraph's obligations under this
Agreement of such other agreements, or seek actual damages arising from such
breach or wrongful termination in lieu of such specific performance.  Each
party's rights to terminate such agreements and be relieved of its obligations
thereunder, or require specific performance or recover actual damages shall be
such party's sole and exclusive remedies for breach or termination of such
agreements.  Intergraph and InterCAP acknowledge and agree that the foregoing
limitation of remedies is not intended as a penalty, and that the exclusive
remedies prescribed above shall be in lieu of all actual, direct, special,
incidental, consequential, punitive or other damage remedies therefor, whether
arising in tort, contract or otherwise, or any other right or remedy under
applicable law.

among the parties with respect to the subject matter hereof and supersedes all
other prior agreements and understandings both written and oral, among the
parties or any of them with respect to the subject matter hereof, and (b) shall
not be assigned by operation of law or otherwise, provided that Intergraph may
assign its rights and obligations to any direct or indirect, wholly-owned
subsidiary of Intergraph, but no such assignment shall relieve Intergraph of its

     NOW, THEREFORE, in consideration of the premises and the mutual covenant
and agreements hereinafter set forth, and such other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
parties, intending to be legally bound, hereby agree as follows:

     1.  Amendment to Certificate of Incorporation.  Each of Venture First,
         -----------------------------------------                         
Biddle and GeoCapital irrevocably covenant and agree to each other and InterCAP
to vote all of the shares of capital stock of InterCAP they now own and
hereafter acquire, or to execute a written consent of stockholders in lieu of

irrevocably agree, and do hereby elect pursuant to Article Fourth, Section IA,
paragraphs 4(c) and 6(i) of the Certificate to receive the liquidation
preference of $1.475 per share of Series A Stock (without further adjustment of
any kind after the date of this Agreement) pursuant to the Merger in respect of
all shares of Series A Stock owned by them, such liquidation preference to be

The execution and delivery of this Agreement shall constitute irrevocable notice
of such election for purposes of Article Fourth, Section 1A, paragraph 6(i) of
the Certificate.

     3.  Exercise of Warrant.  Venture First agrees to exercise the Warrant in
         -------------------                                                  
full immediately prior to the Effective Time, the parties agreeing that the
execution and delivery of this Agreement constitutes sufficient notice of such
exercise.  In connection with the exercise by Venture First of the Warrant,
InterCAP and Venture First agree that, in lieu of the delivery by Venture First
to InterCAP of cash in an amount equal to the Aggregate Warrant Price, Venture
First shall and does hereby relinquish the right to purchase a number of Warrant
Shares at the price set forth in the Warrant such that, upon such exercise,
Venture First shall receive 36,260 shares of InterCAP Common Stock plus cash in
lieu of fractional shares as provided in the Merger Agreement.  InterCAP and
Venture First further agree that the exercise of the Warrant upon the foregoing
terms shall be in full satisfaction of InterCAP's obligations to deliver shares
of InterCAP Common Stock upon exercise of the Warrant.

     4.  Conversion of Series B Stock and Series C Stock.  So long as the
         -----------------------------------------------                 
Effective Time of the Merger occurs on or before January 15, 1995, (i) Venture
First and Biddle irrevocably agree to convert each share of Series B Stock owned
by them into one share of InterCAP 

                                       2
<PAGE>
 
Common Stock prior to the Effective Time in accordance with Article Fourth,
Section IB, paragraph 6(a) of the Certificate; and (ii) GeoCapital irrevocably
agrees to convert each share of Series C Stock owned by it into one share of
InterCAP Common Stock prior to the Effective Time in accordance with Article
Fourth, Section IC, paragraph 6(a) of the Certificate. The execution and
delivery of this Agreement constitutes irrevocable notice to InterCAP (i) by
Venture First and Biddle to convert all shares of Series B Stock owned by them
into InterCAP Common Stock as required by Article Fourth, Section 1B, paragraph
6(d) of the Certificate and (ii) by GeoCapital to convert all shares of Series C
Stock owned by it into InterCAP Common Stock as required by Article Fourth,
Section 1C, paragraph 6(d) of the Certificate.

the Merger Agreement in exchange for their respective shares of Series A Stock

such shares of Series A Stock and Series B Stock and all rights and preferences
attendant thereto (including, by way of illustration and not limitation, rights
to receive accrued but unpaid dividends, rights to receive a liquidation
preference other than $1.475 per share for the Series A Stock in the Merger and
rights to receive a different number of shares of InterCAP Common Stock upon
conversion of the Series B Stock), and until surrendered as contemplated by the
Certificate or the Merger Agreement, as the case may be, each certificate

be deemed, on and after the Effective Time, to represent only the right to
receive upon such surrender, New Certificates representing the applicable number
of shares of Intergraph Common Stock (based on the applicable Exchange Ratio) as
set forth in the Merger Agreement (in all cases without interest).  GeoCapital
agrees that the shares of Intergraph Common Stock and any cash in lieu of
fractional shares to be delivered to GeoCapital in accordance with the terms of
the Merger Agreement in exchange for its shares of Series C Stock shall be in
full satisfaction of all rights pertaining to such shares of Series C Stock and
all rights and preferences attendant thereto (including, by way of illustration
and not limitation, rights to receive accrued but unpaid dividends and the
rights to receive a different number of shares of InterCAP Common Stock upon
conversion of the Series C Stock), and until surrendered as contemplated by the
Merger Agreement each certificate representing its shares of Series C Stock
shall be deemed, on and after the Effective Time, to represent only the right to
receive upon such surrender, New Certificates representing the applicable number
of shares of Intergraph Common Stock (based on the applicable Exchange Ratio) as
set forth in the Merger Agreement (in all cases without interest).

     6.  Governing Law.  This Agreement shall be governed by and construed and
         -------------                                                        
enforced in accordance with the laws of the State of Delaware applicable to
agreements made and to be performed entirely within such State without giving

together shall constitute one and the same instrument.

     8.  Assignment.  This Agreement shall be binding upon and inure to the
         ----------

assignment without such consent shall be null and void and of no force or
effect.

     9.  Third Party Beneficiaries.  None of the provisions of this Agreement or
         -------------------------                                              
any document contemplated hereby is intended to grant any right or benefit to
any person or entity which is not a party to this Agreement except that the
parties hereto acknowledge that Intergraph is relying on this Agreement in

is hereafter amended if as a result of such amendment, the rights of the holders
of Series A Stock, Series B Stock or Series C Stock are adversely affected in
any manner whatsoever.

     12. Severability.  In the event that any provision in this Agreement shall

be determined to be invalid, illegal or unenforceable in any respect, the
remaining provisions of this Agreement shall not be in any way impaired, and the
illegal, invalid or unenforceable provision shall be fully severed from this
Agreement and there shall be automatically added in lieu thereof a provision as
similar in terms and intent to such severed provisions as may be legal, valid
and enforceable.

     13. Entire Agreement.  This Agreement sets forth our entire understanding
         ----------------

represent a legally binding agreement upon execution by each of us.  This
Agreement will be enforceable against each party hereto and its successors and
assigns (including any transferee of any shares of Series A Stock and Series B
Stock of Venture First or Biddle and including any transferee of any shares of
Series C Stock of GeoCapital) in accordance with its terms.  If requested by
InterCAP, Venture First, Biddle and GeoCapital agree to submit all certificates
representing the Series A Stock, the Series B Stock and the Series C Stock to
InterCAP for the placement thereon of a legend referencing the existence and
restrictions in this Agreement.  Pending the placement of such 

                                       4

legends on such certificates, Venture First, Biddle and GeoCapital shall not

                                ESCROW AGREEMENT


     THIS ESCROW AGREEMENT ("Agreement"), dated as of , 1994, among Intergraph
Corporation, a Delaware corporation ("Parent"), A.G.W. Biddle, III, John C.
Gebhardt and Joy E. Binford (the "Stockholders' Committee") and , in its
capacity as Escrow Agent hereunder (the "Escrow Agent", which term shall also
include any successor escrow agent appointed in accordance with Section 10(b)
hereof).

     Reference is made to the Agreement and Plan of Reorganization dated as of
September , 1994 (the "Reorganization Agreement"), among Parent, Intergraph DC
Corporation-Subsidiary-7, a Delaware corporation and a wholly-owned subsidiary
of Parent (the "Acquisition Sub"), and InterCAP Graphics Systems, Inc., a
Delaware corporation (the "Company"), providing for, among other things, the
merger (the "Merger") of Acquisition Sub with and into the Company, with the
Company surviving the Merger as a wholly-owned subsidiary of Parent and the
stockholders of the Company receiving shares of Intergraph Common Stock in
exchange for shares of InterCAP Stock, in the manner provided in the
Reorganization Agreement.  As used herein, the term "Reorganization Agreement"
shall be deemed to mean and include the Reorganization Agreement and all of the
schedules and exhibits thereto and all other agreements executed and delivered
in connection therewith.  All capitalized terms used but not defined herein
shall have the meanings ascribed thereto in the Reorganization Agreement.

     This Agreement is designed to implement the provisions of the
Reorganization Agreement pursuant to which Parent, on behalf of the
Stockholders, is depositing with the Escrow Agent shares of Intergraph Common
Stock issued in the Merger to the Stockholders as security for the satisfaction
of the indemnification obligations of the Stockholders pursuant to Section 9.2
of the Reorganization Agreement.

     NOW, THEREFORE, to induce Parent to enter into, and in consideration of
Parent entering into, the Reorganization Agreement, and in consideration of the
premises and the representations and warranties and agreements contained herein,
the parties hereto agree as follows:

     1.  Appointment of Escrow Agent.  The Escrow Agent is hereby appointed to
         ---------------------------                                          
act as escrow agent hereunder and the Escrow Agent agrees to act as such.

     2.  Stockholders' Committee.  Pursuant to Section 9.2(f) of the
         -----------------------                                    
Reorganization Agreement, the Stockholders have, by their approval of the
Merger, constituted and appointed as their agents and attorneys-in-fact (who, by
execution of this Agreement, will be deemed to accept such appointment) a
committee of three persons, to consist initially of A.G.W. Biddle, III, John C.
Gebhardt and Joy E. Binford and such other persons as from time to time may be
designated in substitution therefor as the "Stockholders' Committee", with full
power and authority to take all action required or permitted under this
Agreement (including, but not limited to, the giving and receipt of all notices
and consents and the execution and delivery of all documents, including any
amendments hereto and any agreements and releases in connection with 
<PAGE>
 
the settlement of disputes hereunder). The vote of a majority of the
Stockholders' Committee shall be required to take any action on behalf of the
Stockholders pursuant to the authority granted to them under Section 9.2(f) of
the Reorganization Agreement and this Section 2. The reasonable expenses
incurred by the Stockholders' Committee in performing its duties as the
Stockholders' Committee as well as the costs of indemnifying or insuring the
Stockholders' Committee pursuant to the Reorganization Agreement (including
reasonable legal fees and expenses of counsel thereto) shall be borne (i) by the
Company up to an aggregate amount not to exceed $5,000; and (ii) severally by
the Stockholders, pro rata based upon the relative number of shares of
                  --- ----            
Intergraph Common Stock delivered into escrow hereunder by or on behalf of such
Stockholders to the extent such expenses exceed $5,000 in the aggregate.

     3.  Escrow Fund and Escrow Account.
         ------------------------------ 

         (a) On the date hereof, in accordance with Section 2.2(a) of the
Reorganization Agreement, Parent is delivering (or causing the Exchange Agent to
deliver) to the Escrow Agent one or more certificates representing the Escrow
Shares and the Escrow Agent is accepting such certificates in escrow for the
benefit of the Stockholders and the Indemnified Persons pursuant to the
provisions of this Agreement.  The shares of Intergraph Common Stock delivered
to the Escrow Agent pursuant to this Section 3(a), together with any dividends
or distributions in cash, stock or property or any securities of Parent issued
in respect thereof (including, without limitation, any shares issued pursuant to
any stock dividend, stock split, reverse stock split, combination or
reclassification thereof) shall become part of, and are hereinafter referred to
collectively as, the "Escrow Fund."

         (b) The Escrow Agent shall establish a segregated account (the "Escrow
Account") at its office located at its address set forth in Section 11(a) of
this Agreement in which to hold the Escrow Fund.

     4.  Rights to the Escrow Fund.  The Escrow Fund shall be for the exclusive
         -------------------------                                             
benefit of the Stockholders and the Indemnified Persons and their respective
successors and assigns, as provided herein and in the Reorganization Agreement,
and no other person or entity shall have any right, title or interest therein.

     5.  Distribution of the Escrow Fund.  The Escrow Agent shall continue to
         -------------------------------                                     
hold the Escrow Fund in its possession until authorized hereunder to distribute
the Escrow Fund.  The Escrow Agent shall distribute the Escrow Fund as follows:

         (a) In the event any Indemnified Person (the "Claiming Person") asserts
a right of indemnity against the Stockholders under Section 9.2 of the
Reorganization Agreement, the Claiming Person shall execute and deliver to the
Escrow Agent (with a copy being sent simultaneously to the Stockholders'
Committee) a written notice to such effect (a "Notice of Claim"; and the right
of indemnity asserted in a Notice of Claim being hereinafter referred to as 

                                       2
<PAGE>
 
a "Claim") and instructing the Escrow Agent to deliver that portion of the
Escrow Fund the Fair Market Value (as defined in Section 6 hereof) of which
shall equal the amount of the Claim (or, if the amount of the Claim shall be
greater than the Fair Market Value of the Escrow Fund, the balance of the Escrow
Fund) to such Claiming Person and the following shall apply:

               (i)  a Notice of Claim delivered to the Escrow Agent pursuant to
         this Section 5(a) shall set forth the nature and details of such Claim
         (to the extent known), and the amount thereof (or if not ascertainable,
         a reasonable maximum amount thereof); and

               (ii) if within 10 business days after receipt of any Notice of
         Claim by the Escrow Agent pursuant to this Section 5(a), the
         Stockholders' Committee fails to notify the Escrow Agent that the
         Claim, or the amount thereof, is disputed, the Escrow Agent shall,
         within 5 days after the expiration of such 10-day period, deliver to
         the Claiming Person that portion of the Escrow Fund the Fair Market
         Value of which shall equal the amount of the Claim as set forth in such
         Notice of Claim (or, if the amount of the Claim shall be greater than
         the Fair Market Value of the entire Escrow Fund as of such date, the
         balance of the Escrow Fund) (the date of any such delivery being
         referred to herein as a "Release Date"). If the Stockholders' Committee
         does so notify the Escrow Agent of such dispute (a copy of such notice
         being simultaneously sent to the Claiming Person), the Escrow Agent
         shall not deliver such amount to such Claiming Person (or to the
         Stockholders pursuant to Section 5(c) hereof) until 5 days after such
         dispute has been settled as provided in Section 11 hereof and notice of
         such settlement and of the amount, if any, to be paid in respect of the
         disputed Claim has been delivered to the Escrow Agent and the
         Stockholders' Committee (the date of receipt of any such notice being
         referred to herein as a "Settlement Notice Date"; and a Release Date or
         a Settlement Notice Date being referred to herein as a "Determination
         Date").

         (b) Anything contained herein to the contrary notwithstanding, if the
Escrow Agent is authorized, at any time pursuant to Section 5(a) hereof, to
deliver all or any portion of the Escrow Fund to Parent with respect to a Claim
or Claims, then such delivery shall be made regardless of the Escrow Agent's
prior or subsequent receipt of any Notice of Claim or Notice of Dispute with
respect to any other Claim or Claims.

         (c) Subject to Section 5(a) hereof, on the ninetieth (90th) day after
the Closing Date, the Escrow Agent shall distribute to the Stockholders the
entire balance, if any, of the Escrow Fund, that is in excess of the aggregate
amounts specified in all Notices of Claim which, prior to such date, have not
been paid to Parent or otherwise discharged pursuant to this Section 5. Any
portion of the Escrow Fund which shall continue to be held by the Escrow Agent
pursuant to the preceding sentence shall be so held until such time as all
disputed Claims 

                                       3
<PAGE>
 
hereunder have been settled and notice of such settlement or settlements setting
forth the amounts to be paid to Parent, on the one hand, and the Stockholders,
on the other hand, have been delivered to the Escrow Agent. If a portion of the
Escrow Fund is to be delivered to the Stockholders as provided in this Section
5(c), the Escrow Agent shall disburse such portion of the Escrow Fund as
follows:

               FIRST, to each Stockholder who has previously exchanged his or
         its Old Certificates of InterCAP Stock in the manner provided in
         Section 2.2(b) of the Reorganization Agreement, that number of shares
         of Intergraph Common Stock (the "Distributable Shares") as shall equal
         such Stockholders pro rata portion of the Escrow Fund based on his or
                           --- ----               
         its relative contribution of the Escrow Shares to the Escrow Fund,
         together with any cash, property or securities of Parent issued in
         respect of such Distributable Shares (including, without limitation,
         any shares issued pursuant to any stock split, reverse stock split,
         combination or reclassification thereof); and

               SECOND, to Parent (to hold for the benefit of such Stockholders
         pursuant to Section 2.2(e) of the Reorganization Agreement) the balance
         thereof with respect to those Stockholders, if any, who have failed to
         exchange their Old Certificates in the manner contemplated by Section
         2.2(b) of the Reorganization Agreement.

               (c) Notwithstanding anything in this Agreement to the contrary,
if the Stockholders' Committee executes and delivers to the Escrow Agent (with a
copy being sent simultaneously to the Parent) a written notice instructing the
Escrow Agent to distribute that portion of the Escrow Fund as is attributable to
each Stockholder on whose behalf thirty (30) or fewer Escrow Shares were
initially contributed to the Escrow Account, the Escrow Agent shall distribute
such portion of the Escrow Fund to such Stockholders, pro rata based on this
                                                      --- ----               
relative contribution of Escrow Shares to the Escrow Fund.

               (d) To facilitate the distribution of Escrow Shares from the
Escrow Account in accordance with the terms of this Section 5, the Escrow Agent
is authorized to present certificates representing the Escrow Shares to the
Exchange Agent for split-up, reissuance and delivery by the Exchange Agent to
Parent, Claiming Person or Stockholders, as the case may be.

     6.  Valuation.  For all purposes of this Agreement, the "Fair Market Value"
         ---------                                                              
of any property (other than cash and shares of Intergraph Common Stock)
contained in the Escrow Fund as of any date shall be the fair market value of
such property as of such date as determined by the Board of Directors of Parent
in the good faith exercise of its reasonable business judgment, and the "Fair
Market Value" per share of Intergraph Common Stock shall be the Share
Determination Market Price.

                                       4
<PAGE>
 
     7.  Stockholder Rights.  Anything contained herein to the contrary
         ------------------                                            
notwithstanding, the holder of shares of Intergraph Common Stock held in the
Escrow Account shall at all times retain and have the full and absolute right to
exercise, all rights and indicia of ownership, including, without limitation,
voting and consensual rights, other than the right to receive dividends and
other distributions in respect of, and the right to transfer or otherwise
dispose of, such shares while such shares remain subject to this Agreement. If
any such shares of Intergraph Common Stock are transferred to the Parent
pursuant to Section 5 hereof in satisfaction of a Claim or Claims, all rights
and indicia of ownership shall thereupon reside with the Parent or any
subsequent holders thereof.

     8.  Termination.  This Agreement may be terminated at any time by and upon
         -----------                                                           
the receipt by the Escrow Agent of 10 days' prior written notice of termination
executed by Parent and the Stockholders' Committee directing the distribution of
all property then held by the Escrow Agent under and pursuant to this Agreement.
This Agreement shall automatically terminate if and when all amounts in the
Escrow Account (including all the securities in which any funds contained in the
Escrow Account shall have been invested) shall have been distributed by the
Escrow Agent in accordance with the terms of this Agreement.

     9.  Escrow Agent.
         ------------ 

         (a)   Obligations.
               ----------- 

               (i) The obligations of the Escrow Agent are those specifically
provided in this Agreement, and the Escrow Agent shall have no liability under,
or duty to inquire into the terms and provisions of, any agreement among the
other parties hereto. The duties of the Escrow Agent are purely ministerial in
nature, and it shall not incur any liability whatsoever, except for willful
misconduct or gross negligence. The Escrow Agent may consult with counsel of its
choice, and shall not be liable for following the advice of such counsel.

               (ii) The Escrow Agent shall not have any responsibility for the
genuineness of validity of any document or other item deposited with it or of
any signature thereon and shall not have any liability for acting in accordance
with any written instructions or certificates given to it hereunder and believed
by it to be signed by the proper parties.

         (b) Resignation and Removal.  The Escrow Agent may resign and be
             -----------------------
discharged from its duties hereunder at any time by giving at least 30 days'
prior written notice of such resignation to Parent and the Stockholders'
Committee, specifying a date upon which such resignation shall take effect;
provided, however, that the Escrow Agent shall continue to serve until its
- --------  -------
successor accepts the Escrow Fund. Upon receipt of such notice, a successor
escrow agent shall be appointed by Parent and the Stockholders' Committee, such
successor escrow agent to become the Escrow Agent hereunder on the resignation
date specified in such notice. If a written instrument of acceptance by a
successor escrow agent shall not have been 

                                       5
<PAGE>
 
delivered to the Escrow Agent within 40 days after the giving of such notice of
resignation, the resigning Escrow Agent may at the expense of Parent petition
any court of competent jurisdiction for the appointment of a successor escrow
agent. Parent and the Stockholders' Committee, acting jointly, may at any time
substitute a new escrow agent by giving 10 days' prior written notice thereof to
the Escrow Agent then acting and by Parent paying all fees and expenses of such
Escrow Agent.

         (c) Indemnification.  Parent shall hold the Escrow Agent harmless and
             ---------------                                                  
indemnify the Escrow Agent against any loss, liability, expense (including
attorneys' fees and expenses), claim or demand (a "Loss") that may be incurred
by the Escrow Agent arising out of or in connection with the performance of its
obligations in accordance with the provisions of this Agreement as a consequence
of Parent's action; the Stockholders (to the extent of their rights in the
Escrow Fund) shall severally hold the Escrow Agent harmless and indemnify the
Escrow Agent against any Loss that may be incurred by the Escrow Agent arising
out of or in connection with the performance of its obligations in accordance
with the provisions of this Agreement as a consequence of the Stockholders'
action; and each of the Parent, on the one hand, and the Stockholders, on the
other hand (which Stockholders shall be severally liable therefor, pro rata
                                                                   --- ----
based upon the relative number of shares of Intergraph Common Stock held in
escrow hereunder by or on behalf of such Stockholders) shall hold the Escrow
Agent harmless and indemnify the Escrow Agent against 50% of any Loss arising
out of or in connection with the performance of its obligations in accordance
with the provisions of this Agreement which are not the consequence of any
action of any other party hereto, except for any of the foregoing arising out of
the gross negligence of willful misconduct of the Escrow Agent.  The foregoing
indemnities in this paragraph shall survive the resignation or substitution of
any Escrow Agent or the termination of this Agreement.

         (d) Fees of Escrow Agent. Parent shall pay the Escrow Agent 100% of the
             -------------------- 
fees set forth on Schedule I hereto from and after the date hereof as
compensation for the ordinary administrative services to be rendered hereunder
and all other reasonable fees and expenses of the Escrow Agent, including
reasonable attorneys' fees and expenses, if any, which it may incur in
connection with the performance of its duties under this Agreement.

     10.  Disputes.  If any dispute should arise with respect to the payment or
          --------                                                             
ownership or right of possession of the Escrow Fund, or the duties of the Escrow
Agent hereunder, the Escrow Agent is authorized and directed to retain in its
possession, without liability to anyone, all or any part of the Escrow Fund
until such dispute shall have been settled either by mutual agreement of Parent
and the Stockholders' Committee (evidenced by appropriate instructions in
writing to the Escrow Agent signed by Parent and the Stockholders' Committee) or
by the final order, decree or judgment of a court of competent jurisdiction in
the United States of America (the time for appeal having expired with no appeal
having been taken) in a proceeding to which Parent and the Stockholders'
Committee are parties, but the Escrow Agent shall be under no duty whatsoever to
institute or defend any such proceedings.  In the event of any dispute between
or 

                                       6
<PAGE>
 
among any of the parties to this Agreement, or between or among them or any of
them and any other person, resulting in adverse claims or demand being made upon
the Escrow Fund, or in the event that the Escrow Agent, in good faith, is in
doubt as to what action it should take hereunder, the Escrow Agent may, at its
option, file a suit in interpleader in a court of competent jurisdiction, or
refuse to comply with any claims or demands on it, or refuse to take any other
action hereunder, so long as such dispute shall continue or such doubt shall
exist. The Escrow Agent shall be entitled to continue to so refrain from acting
until (a) the rights of all parties have been fully and finally adjudicated by
the final order, decree or judgment of a court of competent jurisdiction in the
United States of America (the time for appeal having expired with no appeal
having been taken) or (b) all differences shall have been adjusted and all doubt
resolved by agreement among all of the interested persons, and in each case the
Escrow Agent shall have been notified thereof in a writing signed by all such
persons.

                        InterCAP Graphics Systems, Inc.
                      1989 Employee Stock Option Agreement


          THIS EMPLOYEE STOCK OPTION AGREEMENT entered into this 6th day of
June, 1994 between InterCAP Graphics Systems, Inc., a Delaware corporation,
having its principal office at 116 Defense Highway, Annapolis, Maryland 21401
(hereinafter referred to as "Company") and ___________________, an individual
residing in the state of Maryland (hereafter referred to as the "Optionee").

                                  WITNESSETH:
                                  -----------

          WHEREAS, the Optionee is now engaged in the performance of services 
for the Company as an employee of the Company, and

          WHEREAS, the Company desires that the Optionee continue to engage in
services on behalf of the Company and the Company desires to afford the Optionee
an additional incentive pursuant to its 1989 Employee Stock Option Plan (the
"Plan"), a copy of which is attached hereto as Exhibit A and the terms of which
are incorporated herein by reference, to either acquire or increase, as the case
may be, his proprietary interest in the success of the Company;

          NOW, THEREFORE, in consideration of the premises and of the mutual
agreements hereinafter set forth, the parties hereto hereby mutually agree as
follows:

          1.   Grant of Option.  Subject to the terms and conditions 
               ---------------
hereinafter set forth, the Company hereby grants to the Optionee, in
consideration of his continued service on behalf of the Company, the option to
purchase during the period specified in Section 2, and at the purchase price
specified in Section 3, all of or any part of 10,000 shares (the "Shares") of
the Common Stock of the Company, which Shares when issued upon the exercise of
such option and paid for in accordance with the terms hereof shall be fully paid
and nonassessable. This option shall be an incentive stock option ("ISO") within
the meaning of Section 422A of the Internal Revenue Code of 1986, as amended
(the "Code").

          2.   Period and Exercise.
               -------------------

          A.   No part of this option may be exercised (i) before the first 
anniversary of issuance (the "Date of Grant"), or (ii) more than ten years 
from the date of issue. The minimum number of Shares with respect to which 
this option may be exercised in part at one time shall be 100. Subject to the 
foregoing and to the provisions of Sections 4 and 5 hereof, the Optionee may 
exercise this option as follows:

               (i) at any time or times from the Date of Grant through the first
     anniversary of the Date of Grant, the Optionee may exercise this option as
     to any number of Shares up to 25% of the total number of Shares covered
     hereby;
<PAGE>
 
               (ii)   at any time or times from the first anniversary of the 
     Date of Grant through the second anniversary of the Date of Grant, the 
     Optionee may exercise this option as to any number of Shares which, when 
     added to the Shares as to which the Optionee has theretofore exercised 
     this option, will not exceed 50% of the total number of Shares covered 
     hereby;

               (iii)  at any time or times from the second anniversary through
     the third anniversary of the Date of Grant, the Optionee may exercise this
     option as to any number of Shares which, when added to the Shares as to
     which the Optionee has theretofore exercised this option will not exceed
     75% of the total number of Shares covered hereby; and

               (iv)   at any time or times from after the third anniversary of
     the Date of Grant through the tenth year after the original issue, the
     Optionee may exercise this option as to any number of Shares which, when
     added to the Shares as to which the Optionee has theretofore exercise this
     option, will not exceed the total number of Shares covered hereby.

          B.   Except as otherwise provided in Sections 4 or 5, this option
shall be exercisable only if the Optionee has remained in continuous employment
with the Company from the Date of Grant until the date of the proposed exercise.
For the purpose of this Agreement, a period of engagement as an employee or
officer shall be considered continuing intact for any period that the Optionee
is on military or sick leave or other bona fide leave of absence, provided that
the period of such leave does not exceed ninety days, or, if longer, as long as
the Optionee's right to re-employment is guaranteed either by statute or by
contract.  The period of engagement as an employee or officer shall also be
considered continuing intact while the Optionee is not in active service because
of disability.  For purposes of this Section 2(B), "disability" shall mean the
inability of the Optionee to engage in any substantial gainful activity by
reason of any medically determinable physical or mental impairment which can be
expected to result in death, or which has lasted or can be expected to last for
a continuous period of not less than twelve months.  The Committee (as defined
below) shall determine whether the Optionee is disabled within the meaning of
this Section 2(B).  Subject to the limitations of this Section 2(B) above with
respect to the permissible length of a leave of absence, in authorizing a leave
of absence the Board of Directors of the Company (the "Board") or the
Compensation Committee of the Board (the "Committee") may, in its discretion,
give credit for the time of such leave in computing whether sufficient time has
elapsed for the option or any part thereof to be exercised.  Termination of a
period of engagement as an employee or officer of the Company to enter the
employ or serve as an officer of a subsidiary corporation (as defined in Section
425(f) of the Code) of the Company, as the case may be, shall not be deemed to
interrupt continuous employment.

          C.   This option may be exercised pursuant to its terms by the
Optionee's giving written notice thereof to the Secretary or Treasurer of the
Company at its then principal office.  Such notice shall state the number of
Shares with respect to which the option is being exercised

                                       2
<PAGE>
 
and shall be accompanied by payment in full of the purchase price for such
Shares in cash, by certified or bank cashier's check payable to the order of the
Company.

          In the event this option shall be exercised, pursuant to Section 5, by
any person other than the Optionee, the aforesaid notice shall also be
accompanied by appropriate proof of the right of such person to exercise the
same.

          D.   The stock certificates evidencing the Shares acquired upon
exercise of the option, if such Shares are not covered by a registration
statement under the Securities Act of 1933, as amended (the "Securities Act"),
and are not registered under applicable state securities laws, shall bear the
following legend:

               "These securities have not been registered under the Securities
     Act of 1933, as amended, or under any applicable state securities laws.
     They may not be sold, offered for sale, pledged, hypothecated or otherwise
     transferred unless registered under said Act and under any applicable state
     securities laws or unless, in the opinion of counsel for the Company, such
     registration is not required."

          E.   The Company may in its discretion require, regardless of whether
a registration statement under the Securities Act and under applicable state
securities laws is then in effect with respect to the Shares issuable upon such
exercise, or the offer and sale of such Shares are exempt from the registration
provisions of the Securities Act and of any applicable state securities laws,
that as a condition precedent to the exercise of this option, the person
exercising the option give to the Company a written representation and
undertaking, satisfactory in form and substance to the Company, that he or she
is acquiring the Shares for his or her own account for investment and not with a
view to the distribution or resale thereof and otherwise establish to the
Company's satisfaction that the offer or sale of the Shares issuable upon
exercise of the option will not constitute or result in any breach or violation
of the Securities Act, any applicable state securities laws, or any similar act
or statute or any rulings or regulations thereunder.

          3.   Option Price.  Subject to the provisions of Section 8, the option
               ------------                                                     
price per Share shall be $_________.  Such price has been found by the Board to
be not less than 100% of the fair market value per Share as of the Date of
Grant.

          4.   Termination of Option.  In the event of the termination of the
               ---------------------                                         
service of the Optionee as an officer or employee: (i) involuntarily, for cause
(which shall include, without limitation, termination for breach of his or her
employment agreement, if any), or voluntarily, for any reason, this option and
all rights hereunder will automatically terminate simultaneously with the
occurrence of such termination; or (ii) for any reason, except death, this
option and all rights hereunder will automatically terminate on the earlier of
(a) 90 days from the date of termination (as fixed and determined by the
Committee) or (b) the tenth anniversary of the original issue.

                                       3
<PAGE>
 
          5.  Non-Assignability and Death of Optionee.
              --------------------------------------- 

          A.  Notwithstanding anything to the contrary herein contained,
neither this option nor any rights represented hereby shall be transferable or
assignable by the Optionee otherwise than by will or by the laws of descent and
distribution, and this option shall be exercisable during the Optionee's
lifetime only by the Optionee, and any attempt to transfer or assign this option
in violation of the foregoing shall be void and of no force or effect.

          B.  In the event the Optionee's employment by the Company is
terminated because of death: (i) the option may be exercised only to the extent
exercisable by the Optionee on the date of the death of the Optionee; (ii) the
option shall be exercisable only by the executor or administrator of the
Optionee or the person to whom the Optionee's rights under the option shall pass
by the will of the Optionee or the laws of descent and distribution; and (iii)
the option may only be exercised within one year of the date of death of the
Optionee, but in no event after the tenth anniversary of the original issue.

          6.  Repurchase of Shares.
              -------------------- 

          A.  If, for any reason, including, without limitation, discharge,
retirement, disability or death, the Optionee ceases to be an employee of the
Corporation or a related corporation within three years of the Date of Grant,
the Corporation shall have the right (but shall not be obligated) to repurchase
all Shares acquired pursuant to this Agreement, including Shares acquired
following termination of the Optionee's employment pursuant to the exercise of
the option granted hereunder by the Optionee, the Optionee's estate, or any
person acquiring the Option by will or the laws of intestate succession (the
"Repurchase Shares").

          B.  If the Corporation desires to repurchase the Repurchase Shares,
the Corporation shall provide written notice of its desire to repurchase within
ninety days following termination of the Optionee's employment by the
Corporation (or, with respect to Shares acquired through the exercise of options
following the close of such ninety-day period, within thirty days following the
date of such exercise).  Such notice shall be provided to the Optionee, the
Optionee's estate or such other person as may then be the registered holder of
such Repurchase Shares (collectively referred to herein as the "Registered
Holder").  When the Corporation provides such notice to the Registered Holder,
the Registered Holder shall tender the stock certificate or certificates
representing the Repurchase Shares to the Corporation at a Closing to be held on
the tenth business day following the date of the Corporation's notice at 10:00
a.m. at the Corporation's principal place of business, or at such other time and
place as the parties shall agree.  At the Closing, the Corporation shall tender
the purchase price of the Repurchase Shares as provided in Section 6(C).  If the
Corporation shall fail to provide such notice with respect to any Repurchase
Shares, the provisions of this Section 6 shall be inapplicable with respect to
such Shares.

                                       4
<PAGE>
 
          C.  The purchase price of the Repurchase Shares purchased pursuant to
this Section 6 (the "Purchase Price") shall be an amount per Share to be
determined according to the following equation:

          Purchase Price = (R +/- NI) - PSLP
                           -----------------
                                       CSE
          where:

          R    =    the Company's gross revenues from operations for the 12-
                    month period ending as of the last day of the calendar
                    quarter immediately preceding the date of termination of
                    Optionee's employment, computed in accordance with generally
                    accepted accounting principles

          NI   =    the Company's net income (or net loss) for the 12-month
                    period ending as of the last day of the calendar quarter
                    immediately preceding the date of termination of Optionee's
                    employment, computed in accordance with generally accepted
                    accounting principles; in the case of net income, such
                    amount shall be added to R and in the case of net loss, such
                    amount shall be subtracted from R

          PSLP =    the full aggregate liquidation preference to which the
                    holders of the Company's outstanding shares of preferred
                    stock would be entitled as of the date of the termination of
                    Optionee's employment if the Company were deemed to have
                    been subjected to a transaction triggering such a
                    liquidation preference on such date

          CSE  =    the number of shares of Common Stock outstanding as of the
                    date of termination of Optionee's employment calculated on a
                    fully diluted basis assuming the conversion and exchange of
                    all outstanding securities of the Company convertible into
                    or exchangeable for shares of Common Stock and the exercise
                    in full of all outstanding warrants, options or similar
                    rights that are exercisable on the date of such termination
                    without further contingency

The Purchase Price of the Repurchase Shares shall be determined by the Committee
in good faith.  Payment of the Purchase Price for the Repurchase Shares shall be
in cash unless otherwise agreed by the Committee and the Registered Holder.

          D.   Unless the Committee shall otherwise agree, the aggregate
Purchase Price for any Repurchase Shares purchased hereunder shall be reduced by
the amount of any advances or loans made to the Registered Holder by the
Corporation which have not been repaid in full

                                       5
<PAGE>
 
as of the date of the Closing.  If the aggregate amount of such advances or
loans exceeds the Purchase Price of the Repurchase Shares under this Section 6,
the excess shall be and remain until paid the obligation of the Optionee or his
estate.

          E.   The provisions 6(A) through 6(D) shall terminate if the company
is sold as defined in Section (8).

          7.   Listing, Registration and Other Legal Requirements.
               -------------------------------------------------- 

          A.   In the event shares of the Common Stock shall be listed on any
national securities exchange, the Company shall not be required to issue or
deliver any certificate for Shares purchased upon the exercise of this option
prior to completion of listing of such Shares on such national securities
exchange and any other exchange on which the shares of the Common Stock may then
be listed, and prior to the registration of the same under the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), and any similar act or
statute.  In such event, and in the further event of the exercise of this option
with respect to any Shares subject hereto, the Company at its own cost shall
make prompt application for completion of such listing and/or registration of
such Shares as may be necessary.

          B.   The granting and exercise of this option and the Company's
obligation to deliver Shares pursuant to an exercise of this option shall be
subject to all applicable federal and state laws, rules and regulations, and
listing requirements of any stock exchange, and to such approvals by a
regulatory or governmental agency as may be required.  Accordingly, if in the
opinion of the Company, Shares subject to this option are required to be
registered under the Exchange Act or under any applicable state securities laws,
and such registration has not been effected or a prospectus complying with the
requirements of Section 10 of the Securities Act is not available for delivery
upon exercise of this option, the Company shall not be required to deliver the
Shares subject to the option to the extent being exercised until the
registration has been effected and the prospectus made available.  Pending the
satisfaction of the foregoing such exercise shall be deemed suspended and there
shall be returned to the person exercising this option the proceeds representing
the exercise price.  In such event, the Company shall provide notice to the
Optionee or his representative of the satisfaction of the foregoing registration
condition, whereupon the right to exercise this option shall be reinstated.

          C.   In no event shall there first become exercisable by the Optionee
in any one calendar year incentive stock options granted under the Plan or any
other incentive stock option plan of the Company or any parent or subsidiary
corporation (as defined in Sections 425(e) and (f) of the Code) of the Company
with respect to shares having an aggregate fair market value (determined at the
time an option is granted) greater than $100,000.

          8.   Capital Adjustment and Sale of the Company.
               ------------------------------------------ 

          A.   If prior to the expiration of this option there shall be any
stock dividend, stock split, combination or exchange of shares, merger,
consolidation, recapitalization, separation,

                                       6
<PAGE>
 
reorganization, liquidation, extraordinary dividend payable in stock of a
corporation other than the Company, or otherwise than in cash, or any other like
event by or of the Company, and as often as the same shall occur, then the
number, class and kind of shares of stock then subject to this option and the
purchase price per share of such stock shall be appropriately adjusted by the
Committee or the Board to reflect such event so that the Optionee shall be
entitled to receive such number of shares or other securities which the Optionee
would have been entitled to receive had this option been exercised prior to the
occurrence of such event.  The determination of the Committee or the Board in
respect thereof shall be conclusive.

          B.   In the event of (a) the sale of all or substantially all of the
Company's assets, (b) the sale by the Company's stockholders in a single
transaction or a series of related transactions of more than 50% of the
Company's outstanding capital stock, or (c) a merger to which the Company is a
party but in which the Company is not the surviving corporation, or a
consolidation of the Company with another entity, as a result of which the
stockholders of the Company, immediately after such merger or consolidation,
hold less than 50% of the equity securities of the surviving or resulting
corporation (the events described in clauses (a)-(c) above being hereinafter
referred to as the "Subject Events") prior to the full vesting of these options,
then this option shall be deemed immediately exercisable in full as of the day
immediately preceding the date of such Subject Event.

          C.   In the event of (i) the sale by the Company's stockholders in a
single transaction or a series of related transactions of all of the Company's
outstanding capital stock, or (ii) a merger or consolidation as described in
clause (c) of Section 8(B) (the events described in clauses (i) and (ii) above
being hereinafter referred to as the "Sale Events") prior to July 1, 1994, with
respect to all Shares purchased by the Optionee on the day immediately preceding
the date of such Sale Event which Shares became purchasable by the Optionee
solely because of the operation of Section 8(B) hereof (the "Accelerated
Shares"), the amount of cash, securities or other property or consideration (the
"Consideration") payable by the purchaser of the Accelerated Shares (the
"Purchaser") with respect to its purchase of the Accelerated Shares in
connection with the Sale Event shall be payable by the Purchaser to the Optionee
on terms no less favorable than the following:

               (1) One-half of the Consideration (in corresponding increments of
     cash, stock or other property) shall be delivered by the Purchaser to the
     Optionee on the date of closing of the Sale Event (the "Closing"); and

               (2) One-half of the Consideration shall be delivered by the
     Purchaser to an escrow account maintained at a bank or with any other third
     party acceptable to the Purchaser and the Company, such Consideration to be
     disbursed to the Optionee (or to the Purchaser) as follows:

                   (a)   If the Optionee has not voluntarily terminated his or
               her employment with the Company prior to the first anniversary of
               the Closing (the "First Anniversary"), one-half of the remaining

                                       7
<PAGE>
 
               Consideration together with "Interest" thereon as hereinafter
               provided, shall be delivered by the Purchaser to the Optionee on
               the First Anniversary.

                    (b)   If the Optionee has not voluntarily terminated his or
               her employment with the Company prior to the second anniversary
               of the Closing (the "Second Anniversary"), all the remaining
               Consideration, together with all remaining "Interest" thereon as
               hereinafter provided, shall be delivered by the Purchaser to the
               Optionee on the Second Anniversary; and

                    (c)   If the Optionee voluntarily terminates his employment
               with the Company prior to the First Anniversary or the Second
               Anniversary (other than by reason of his or her death or
               disability), all Consideration remaining in the escrow account,
               together with all remaining "Interest" thereon, shall be returned
               to the Purchaser as of the date of such termination.

          All cash Consideration deposited in the escrow account shall bear
interest, payable by the Purchaser, at the rate of ten percent (10%) per annum,
compounded annually.  Any interest earned in the escrow account on cash
Consideration deposited therein shall be applied towards payment of "Interest"
as described below.  In the case that shares of stock, other securities, notes
or other evidences of indebtedness or other property constitute some or all of
the Consideration, the Purchaser shall deposit in the escrow account at the
Closing a number of shares of stock or other units of ownership, or a note or
other evidence of indebtedness with a face value or principal amount, or other
property with a fair market value as determined by the Board, as the case may
be, reasonably expected to be equal to one hundred twenty-one percent (121%) of
the value of shares of stock, or the face value or principal amount of the note
or other evidence of indebtedness, or the fair market value of any other
property otherwise deliverable to the Optionee with respect to the Accelerated
Shares so placed in escrow as it is paid out.  Specifically, the intent of this
provision is that 50% of the face value of the consideration for accelerated
shares shall be paid at closing at 100%.  25% of the consideration shall be paid
on the first anniversary with interest of 10%.  25% of the consideration shall
be paid on the second anniversary plus 21%.  This provision shall apply to cash
and cash like investments.  It shall be assumed that pure equity securities
shall appreciate by 10% annually and no provision for interest shall be made,
though all dividends on those shares shall be added to the escrow account.  The
amount of blended securities (debt and equity like securities) to be placed in
escrow at closing shall be determined by the Board of Directors to meet the
intent of the proceeding, and shall then be forever fixed and not subject to
later adjustment.  Any distribution to the Optionee of Consideration on the
First Anniversary shall include all cash Consideration to be distributed
pursuant to clause (2)(a) above together with interest earned through the First
Anniversary on such cash portion as described above, plus one hundred ten
percent (110%) of the securities or other property constituting the
Consideration to be distributed from the escrow account pursuant to clause
(2)(a).  As used herein, the term "Interest" shall mean interest earned on all
cash

                                       8
<PAGE>
 
Consideration pursuant to this paragraph and all additional shares of stock,
notes or other property required to be deposited by the Purchaser in the escrow
account at the Closing.

          9.   No Other Adjustments.  Except as provided in Section 8, no
               --------------------                                      
adjustments shall be made for dividends or other rights for which the record
shall be prior to the issuance of a stock certificate to the Optionee by reason
of his exercise of this option.

          10.  Rights in Option Stock.  The Optionee shall not be considered a
               ----------------------                                         
record holder of any of the Shares in respect of which he shall exercise this
option until the date on which he shall actually be recorded as the holder of
such Shares upon the stock records of the Company and full payment shall have
been made for the Shares.

          11.  Stock Reserved.  The Company shall at all times during the term
               --------------                                                 
of this Option Agreement reserve and keep available such number of Shares as
will be sufficient to satisfy the requirements of this Option Agreement and
shall pay all original issue taxes, if any, on the exercise option, and all
other fees and expenses necessarily incurred by the Company in connection
therewith.

          12.  Not Employment Agreement.  This Agreement does not constitute an
               ------------------------                                        
employment agreement and shall not confer on the Optionee any right to continue
in the employ of the Company, or prevent, or in any way impair the right of the
Company at any time to terminate the employment of the Optionee as, if
applicable, an officer or employee, with or without cause.

          13.  Termination, Modification, or Amendment of Plan.  The rights of
               -----------------------------------------------                
the Optionee, or the personal representative of the Optionee, or of a
beneficiary of the Optionee who acquires the right to exercise this option by
bequest or inheritance on the death of the Optionee shall not be adversely
affected in any termination, modification, or amendment of the Plan pursuant to
which this option is granted, without the consent of the Optionee or of such
personal representative or beneficiary.

          14.  Liability of Board.  No member of the Board or of the Committee
               ------------------                                             
shall be liable for any action or determination made in good faith in respect of
the Plan or this option.

          15.  Successors.  This Option Agreement shall be binding upon any
               ----------                                                  
successor of the Company.

                        InterCAP Graphics Systems, Inc.
                      Nonqualified Stock Option Agreement


     THIS NONQUALIFIED STOCK OPTION AGREEMENT ("Agreement") entered into this __
day of September, 1994, between InterCAP Graphics Systems, Inc., a Delaware
corporation, having its principal office at 116 Defense Highway, Annapolis,
Maryland 21401 (hereafter referred to as "Company") and _________________, an
individual residing in the state or country, as the case may be, of ____________
(hereafter referred to as the "Optionee").

                                  WITNESSETH:
                                  -----------

     WHEREAS, the Optionee is now engaged in the performance of services for the
Company as an employee of the Company; and

     WHEREAS, pursuant to the Company's 1994 Non-Qualified Stock Option Program
the Board of Directors of the Company has authorized and directed the Company to
issue to the Optionee an option to acquire shares of the Company's Common Stock,
$.01 par value per share (the "Common Stock"), in recognition of past service to
the Company and to induce the present option holders to remain in the employ of
the Company following its merger with Intergraph DC Corporation - Subsidiary 7
("Intergraph Sub"), a Delaware corporation and a wholly-owned subsidiary of
Intergraph Corporation ("Intergraph"), a Delaware corporation;

     NOW, THEREFORE, in consideration of the premises and of the mutual
agreements hereinafter set forth, the parties hereto hereby mutually agree as
follows:

          1.  Grant of Option.  Subject to the terms and conditions hereinafter 
              ---------------
set forth, the Company hereby grants to the Optionee, in consideration of the
Optionee's prior service to the Company and the Optionee's continued service on
behalf of the Company and its successor, the option to purchase during the
period specified in Section 2, and at the purchase price specified in Section 3,
all of or any part of _______ shares (the "Shares") of the Common Stock of the
Company, which Shares when issued upon the exercise of such option and paid for
in accordance with the terms hereof shall be fully paid and nonassessable.  The
effectiveness of the foregoing grant is expressly conditioned on and subject to
the consummation of the merger of Intergraph Sub with and into the Company and
the other transactions (collectively, the "Transactions") contemplated by that
certain Agreement and Plan of Reorganization by and among Intergraph, Intergraph
Sub and the Company dated September ___, 1994 (the "Merger Agreement").
Provided the Transactions are consummated pursuant to the Merger Agreement, the
foregoing grant shall be deemed to have been made immediately before the
consummation of the Transactions.  This option shall be a nonqualified option
under the Internal Revenue Code of 1986, as amended (the "Code").
<PAGE>
 
          2.  Period and Exercise.
              ------------------- 

              A. No part of this option may be exercised (i) before the 
effective date of the consummation of the Transactions pursuant to the Merger
Agreement (the "Date of Grant"), or (ii) after the tenth anniversary of the Date
of Grant (the "Expiration Date"). The minimum number of Shares with respect to
which this option may be exercised in part at one time shall be one-fourth (1/4)
of the Shares. Subject to the foregoing and to the provisions of Sections 4 and
5 hereof, the Optionee may exercise this option as follows:

                 (i)   at any time or times from the Date of Grant through the 
          first anniversary of the Date of Grant, the Optionee may purchase up
          to one-half (1/2) of the Shares;

                 (ii)  at any time or times from the first anniversary of the 
          Date of Grant through the second anniversary of the Date of Grant, the
          Optionee may purchase up to three-fourths (3/4) of the Shares; and

                 (iii) at any time or times from the second anniversary of the 
          Date of Grant through the Expiration Date, the Optionee may purchase
          all of the Shares.

              B. Except as otherwise provided in Sections 4 or 5, this option
shall be exercisable only if the Optionee has remained in continuous employment
with the Company from the date of this Agreement until the date of the proposed
exercise. For purposes of this Agreement, a period of engagement as an employee
or officer shall be considered continuing intact for any period that the
Optionee is on military or sick leave or other bona fide leave of absence,
provided that the period of such leave does not exceed ninety days, or, if
longer, as long as the Optionee's right to re-employment is guaranteed either by
statute or by contract. The period of engagement as an employee or officer shall
also be considered continuing intact while the Optionee is not in active service
because of disability. For the purposes of this Section 2(B), "disability" shall
mean the inability of the Optionee to engage in any substantial gainful activity
by reason of any medically determinable physical or mental impairment which can
be expected to result in death, or which has lasted or can be expected to last
for a continuous period of not less than twelve months. The Board shall
determine whether the Optionee is disabled within the meaning of this Section
2(B). Subject to the limitations of this Section 2(B) above with respect to the
permissible length of a leave of absence, in authorizing a leave of absence the
Board of Directors of the Company may, in its discretion, give credit for the
time of such leave in computing whether sufficient time has elapsed for the
option or any part thereof to be exercised. Termination of a period of
engagement as an employee or officer of the Company to enter the employ or serve
as an officer of a subsidiary or parent corporation (as defined in Section
424(f) of the Code) of the Company, as the case may be, shall not be deemed to
interrupt continuous employment.

                                       2
<PAGE>
 
              C. This option may be exercised pursuant to its terms by the 
Optionee's giving written notice thereof to the Treasurer of the Company at its
then principal office, or as otherwise directed by the Company. Such notice
shall state the number of Shares with respect to which the option is being
exercised and shall be accompanied by payment in full of the purchase price for
such Shares in cash, or by certified or bank cashier's check payable to the
order of the Company.

                 In the event this option shall be exercised, pursuant to
Section 5, by any person other than the Optionee, the aforesaid notice shall
also be accompanied by proof reasonably acceptable to the Company of the right
of such person to exercise the same.

              D. The stock certificates evidencing the Shares acquired upon
exercise of the option, if such Shares are not covered by a registration
statement under the Securities Act of 1933, as amended (the "Securities Act")
and are not registered under applicable state securities laws, shall bear the
following legend:

              "These securities have not been registered under the 
          Securities Act of 1933, as amended, or under any applicable 
          state securities laws.  They may not be sold, offered for 
          sale, pledged, hypothecated or otherwise transferred unless
          registered under said Act and under any applicable state 
          securities laws or unless, in the opinion of counsel for the 
          Company, such registration is not required."

              E. The Company may in its discretion require, regardless of
whether a registration statement under the Securities Act and under applicable
state securities laws is then in effect with respect to the Shares issuable upon
such exercise, or the offer and sale of such Shares are exempt from the
registration provisions of the Securities Act and of any applicable state
securities laws, that as a condition precedent to the exercise of this option,
the person exercising the option give to the Company a written representation
and undertaking, satisfactory in form and substance to the Company, that he or
she is acquiring the Shares for his or her own account for investment and not
with a view to the distribution or resale thereof and otherwise establish to the
Company's satisfaction that the offer or sale of the Shares issuable upon
exercise of the option will not constitute or result in any breach or violation
of the Securities Act, any applicable state securities laws, or any similar act
or statute or any rulings or regulations thereunder.

          3.  Exercise Price.  Subject to the provisions of Section 7, the 
              --------------
exercise price per Share shall be $____.___ (the "Exercise Price").

          4.  Non-Assignability.  Notwithstanding anything to the contrary 
              -----------------
herein contained, neither this option nor any rights represented hereby shall be
transferable or assignable 

                                       3
<PAGE>
 
by the Optionee otherwise than by will or by the laws of descent and
distribution, and this option shall be exercisable during the Optionee's
lifetime only by the Optionee, and any attempt by the Optionee to transfer or
assign this option in violation of the foregoing shall be void and of no force
or effect.

          5.  Termination of Option.
              --------------------- 

              A.  In the event of the termination of the service of the 
Optionee as an officer or employee by the Company for Cause (as hereinafter
defined) or voluntarily by the Optionee for any reason other than breach by the
Company of any written employment agreement (if any) between Optionee and the
Company: (i) the option may be exercised only to the extent exercisable on the
date of such termination; and (ii) the option may only be exercised within 90
days of the date of such termination, but in no event after the Expiration Date.
As used in this Agreement, the term "Cause" shall mean (i) "cause" as defined in
any written employment agreement (if any) between Optionee and the Company, or
(ii) in the absence of such an employment agreement, any of the following: (A)
conviction of the Optionee of a felony involving moral turpitude, (B) gross
malfeasance in the performance of the Optionee's duties, or (C) intentional
substantial damage, theft or destruction by the Optionee of property of the
Company.

              B. In the event the Optionee's employment by the Company is
terminated because of death: (i) on the date of the death of the Optionee, the
vesting period for the numbers of Shares as to which the option may be exercised
shall accelerate and the option shall become fully exercisable as to any
unpurchased Shares; (ii) the option shall be exercisable only by the executor or
administrator of the Optionee or the person to whom the Optionee's rights under
the option shall pass by the will of the Optionee or the laws of descent and
distribution; and (iii) the option may only be exercised within one year of the
date of death of the Optionee, but in no event after the Expiration Date.

              C. In the event the Optionee's employment is terminated by the
Company other than for Cause or by the Optionee due to breach by the Company of
a written employment agreement (if any) between Optionee and the Company: (i) on
the date of such event, the vesting period for the number of Shares as to which
the option may be exercised shall accelerate and the option shall become fully
exercisable as to any unpurchased Shares; and (ii) the option may only be
exercised within 90 days following such termination, but in no event after the
Expiration Date.

          6.  Capital Adjustment; Sale of the Company Subsequent to the 
              ---------------------------------------------------------
              Transactions.
              ------------

              A. If following the consummation of the Transactions and prior to
the expiration of this option there shall be any stock dividend, stock split,
combination or exchange of shares, recapitalization, separation, reorganization,
liquidation, extraordinary dividend payable 

                                       4
<PAGE>
 
in stock of a corporation other than the Company, or otherwise than in cash, or
any other like event by or of the Company, and as often as the same shall occur,
then the number, class and kind of shares of stock then subject to this option
and the purchase price per share of such stock shall be appropriately adjusted
by the Board to reflect such event so that the Optionee shall be entitled to
receive such number of shares or other securities which the Optionee would have
been entitled to receive had this option been exercised prior to the occurrence
of such event. The determination of the Board in respect thereof shall be
conclusive.

              B.  If the Company is merged with or consolidated into any other
corporation (otherwise than as part of the Transactions), or if all or
substantially all of the business or property of the Company is sold, or if the
Company is liquidated or dissolved, or if a tender or exchange offer is made for
all or any part of the Company's voting securities, or if any other actual or
threatened change in control of the Company occurs, the Board, with or without
the consent of the option recipient, may (but shall not be obligated to), either
at the time of or in anticipation of any such transaction, take any of the
following actions that the Board may deem appropriate in its sole and absolute
discretion: (i) cancel any option by providing for the payment to the option
recipient of the excess of the closing sale price of the Shares as reported on
the National Association of Securities Dealers, Inc. Automated Quotations
National Market System on the day immediately prior to such cancellation, over
the Exercise Price of the option (provided, however, that such alternative shall
                                  -----------------                             
only be available to the Board if the vesting of all previously unvested options
held by the option recipient under this Agreement is first accelerated), (ii)
substitute a new option of substantially equivalent value for any option or
(iii) accelerate the exercise terms of any option.

          7.  No Other Adjustments.  Except as provided in Section 7, no 
              --------------------
adjustments shall be made for dividends or other rights for which the record
date shall be prior to the issuance of a stock certificate to the Optionee by
reason of the exercise of this option.

          8.  Rights in Option Stock. The Optionee shall not be considered a
              ----------------------
record holder of any of the Shares in respect of which he or she shall exercise
this option until the date on which the Optionee shall actually be recorded as
the holder of such Shares upon the stock records of the Company and full payment
shall have been made for the Shares.

          9.  Stock Reserved.  The Company shall at all times during the term 
              --------------
of this Option Agreement keep available such number of Shares as will be
sufficient to satisfy the requirements of this Agreement and shall pay all
original issue taxes, if any, on the exercise of this option, and all other fees
and expenses necessarily incurred by the Company in connection therewith.

          10. Not Employment Agreement.  This Agreement does not constitute an
              ------------------------                                        
employment agreement and shall not confer on the Optionee any right to continue
in the employ of the Company, or prevent, or in any way impair the right of the
Company at any time to 

                                       5
<PAGE>
 
terminate the employment of the Optionee as, if applicable, an officer or
employee, with or without cause.

          11. Liability of Board.  No member of the Board shall be liable for 
              ------------------
any action or determination made in good faith in respect of this option.

          12. Successors.  This Agreement shall be binding upon any successor 
              ----------
of the Company. Optionee and the Company acknowledge and agree that upon
consummation of the Transactions, Intergraph will assume the rights and
obligations of the Company under this Agreement. In connection with such
assumption, (i) references in this Agreement to "Shares" shall be deemed to
refer to shares of Intergraph common stock, $.10 par value per share (adjusted
as set forth in (ii) below), (ii) the number of Shares covered by this option
and the Exercise Price shall be adjusted as set forth in Section 2.3 of the
Merger Agreement, (iii) references to the Company shall be deemed to refer to
Intergraph, and (iv) references to the Board shall be deemed to be references to
the Board of Directors of Intergraph. Optionee hereby consents to the foregoing
assumptions.

          13. Notices.  All notices which are provided for under any of the
              -------                                                      
provisions of this Option Agreement shall be in writing, and shall be given by
registered or certified mail, return receipt requested.  Any such notice shall
be deemed to have been given on, and such notice shall be deemed dated, the date
when the same shall have been deposited for mailing, postage prepaid, in a
United States Post Office (except for any notice of change of address, which
shall be deemed given on, and dated, the date the same shall be received).  All
notices provided to be given to the Company shall be addressed to the attention
of the Treasurer of the Company at the Company's principal address, or at such
other address as the Company may designate by notice hereunder.  All notices
provided to be given to the Optionee or to his personal representative or
beneficiary, shall be addressed to him or her at the address of the Optionee set
forth above, or at such other address as he or she may designate by notice
hereunder.

          14. Fractional Shares.  The Company shall not be required to issue any
              -----------------                                                 
fractional Share upon exercise of this option, but it shall pay to the Optionee,
or to his personal representative or beneficiary who acquires the right to
exercise this option by bequest or inheritance on the death of the Optionee, the
cash equivalent of any fractional share interests, as determined in the sole
discretion of the Board.

          15. Withholding.  Whenever the Company proposes or is required to 
              -----------
issue or transfer Shares, the Company shall have the right to require the
Optionee, prior to the issuance or delivery of any certificates for such Shares,
to remit to the Company, or provide indemnification satisfactory to the Company
for, an amount sufficient to satisfy any federal, state, local, and foreign
withholding tax requirements incurred as a result of an option exercise by such
Optionee.

          16. Governing Law.  This Agreement shall be deemed made in the State 
              -------------
of Delaware and shall be governed by and construed and enforced in accordance
with the laws of such State applicable to contracts made and to be performed in
such State without giving effect to the principles of conflict of laws.

duly executed on the day and year first above written.

     The undersigned understands and agrees that it is intended that the Merger

     The undersigned understands and agrees that it is intended that the Merger
will be treated as a "reorganization" for federal income tax purposes.  The

     The undersigned hereby certifies to Intergraph and InterCAP as follows:

     (a)  The undersigned has, and as of the Effective Time of the Merger will
     have, no present plan or intent to engage in a sale, exchange, transfer,

     Distribution").

     (b)  To the best of the undersigned's knowledge and after due investigation
     and inquiry, in the event the undersigned has, or as of the Effective Time
     of the Merger will have, a present plan or intention to make a Required
     Distribution within two years of the Effective Time of the Merger, each of
     the recipients of the shares of Intergraph Common Stock in the Required
     Distribution has, and as of the Effective Time of the Merger will have, no

Biddle, III ("Biddle"), Venture First II L.P. ("VFL") and GeoCapital II, L.P.

stock redemption obligations for the Company's Series A Convertible Preferred 
Stock, $.01 par value per share ("Series A Stock"), Series B Convertible 
Preferred Stock, $.01 par value per share ("Series B Stock"), and Series C 
Convertible Preferred Stock, $.01 par value per share ("Series C Stock" and, 
together with the Series A Stock and the  Series B Stock collectively 
referred to as the "Preferred Stock"). As of the date hereof, VFL and Biddle own
all the outstanding shares of Series A Stock, VFL and Biddle own substantially 
all of the outstanding shares of the Series B Stock and GeoCap owns all the

     1.   Notwithstanding the provisions of ARTICLE FOURTH, Section IA, 
paragraph 7 of the Certificate of Incorporation of the Company with respect to 
the Series A Stock, Section IB, paragraph 7 of the Certificate of Designations 
of the Company with respect to the Series B Stock and Section IC, paragraph 7 of
the Certificate of Designations of the Company with respect to the Series C 
Stock (collectively, the "Redemption Provisions"), and notwithstanding the 
provisions of paragraph 1(a) and (b) of the letter agreement among the Company, 
VFL and GeoCap dated December 9, 1991, Biddle, VFL and GeoCap hereby waive and 
agree to postpone the right to have their respective shares of Preferred Stock 
redeemed in accordance with the Redemption Provisions on the Sinking Fund 
Payment Date

(as defined in the Redemption Provisions) which otherwise would occur on January
2, 1995.  This waiver and agreement to postpone the Sinking Fund Payment Date is
effective until January 16, 1995 unless such date is further waived or postponed
by a written agreement signed by the holders of all the Preferred Stock (which 
date, as so waived or postponed, shall be treated as the first Sinking Fund 
Payment Date for purposes of the Redemption Provisions).

    2.  Upon the Company's request, GeoCap, Biddle and VFL agree to vote all 
shares of the Company's capital stock held by them and to do or cause to be done
all such other acts and to execute and deliver all such agreements,
certificates, written consents of stockholders, undertakings or other documents
and instruments necessary to amend the Company's Certificate of Incorporation
with respect to the Preferred Stock or waive or postpone compliance by the
Company with the Redemption Provisions consistent with the intent and purposes
of paragraph 1 above.

    3.  This letter sets forth our agreement concerning the matters discussed 
herein, shall represent a legally binding agreement upon execution by each of 
us.  This letter is intended to serve as written notice waiving the rights of 
the undersigned as contemplated by paragraph 7(g) of each of the Redemption 
Provisions.  This letter will be enforceable against each party hereto and its 
successors and assigns (including any Preferred Stock transferee) in accordance 
with its terms.  The parties hereto each hereby consent to specific performance 
of their obligations hereunder by the other parties hereto.  At the request of 
VFL, Biddle and GeoCap, the Company will place a legend on any certificate for 
Preferred Stock that refers to this letter agreement and indicates that the 
shares evidenced thereby are subject hereto.

    If the foregoing correctly sets forth our agreement, please sign below and 
return an original executed counterpart to me by December 7, 1994.

                                        Very truly yours,

                               SECTION 262 OF THE
                       DELAWARE BUSINESS CORPORATION ACT
<PAGE>
 
                                   APPENDIX C

                               SECTION 262 OF THE
                       DELAWARE BUSINESS CORPORATION ACT

          262  APPRAISAL RIGHTS.--(a)  Any stockholder of a corporation of this
State who holds shares of stock on the date of the making of a demand pursuant
to subsection (d) of this section with respect to such shares, who continuously
holds such shares through the effective date of the merger or consolidation, who
has otherwise complied with subsection (d) of this section and who has neither
voted in favor of the merger or consolidation nor consented thereto in writing
pursuant to (S)228 of this title shall be entitled to an appraisal by the Court
of Chancery of the fair value of his shares of stock under the circumstances
described in subsections (b) and (c) of this section.  As used in this section,
the word "stockholder" means a holder of record of stock in a stock corporation
and also a member of record of a nonstock corporation; the words "stock" and
"share" mean and include what is ordinarily meant by those words and also
membership or membership interest of a member of a nonstock corporation.

          (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to (S)251, 252, 254, 257, 258 or 263 of this title:

          (1) Provided, however, that no appraisal rights under this section
shall be available for the shares of any class or series of stock which, at the
record date fixed to determine the stockholders entitled to receive notice of
and to vote at the meeting of stockholders to act upon the agreement of merger
or consolidation, were either (i) listed on a national securities exchange or
designated as a national market system security on an interdealer quotation
system by the National Association of Securities Dealers, Inc. or (ii) held of
record by more than 2,000 stockholders; and further provided that no appraisal
rights shall be available for any shares of stock of the constituent corporation
surviving a merger if the merger did not require for its approval the vote of
the stockholders of the surviving corporation as provided in subsection (f) of
(S)251 of this title.

          (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
under this section shall be available for the shares of any class or series of
stock of a constituent corporation if the holders thereof are required by the
terms of an agreement of merger or consolidation pursuant to (S)(S)251, 252,
254, 257, 258 and 263 of this title to accept for such stock anything except:

          a.  Shares of stock of the corporation surviving or resulting from 
such merger or consolidation;

          b.  Shares of stock of any other corporation which at the effective
date of the merger or consolidation will be either listed on a national
securities exchange or designated as a national market system security on an
interdealer quotation system by the National Association of Securities Dealers,
Inc. or held of record by more than 2,000 stockholders;
<PAGE>
 
          c.  Cash in lieu of fractional shares of the corporations described in
the foregoing subparagraphs a. and b. of this paragraph; or

          d.  Any combination of the shares of stock and cash in lieu of
fractional shares described in the foregoing subparagraphs a., b. and c. of this
paragraph.

          (3) In the event all of the stock of a subsidiary Delaware corporation
party to a merger effected under (S)253 of this title is not owned by the parent
corporation immediately prior to the merger, appraisal rights shall be available
for the shares of the subsidiary Delaware corporation.

          (c) Any corporation may provide in its certificate of incorporation
that appraisal rights under this section shall be available for the shares of
any class or series of its stock as a result of an amendment to its certificate
of incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation.  If the certificate of incorporation contains such a provision,
the procedures of this section, including those set forth in subsections (d) and
(e) of this section, shall apply as nearly as is practicable.

          (d) Appraisal rights shall be perfected as follows:

          (1) If a proposed merger or consolidation for which appraisal rights
are provided under this section is to be submitted for approval at a meeting of
stockholders, the corporation, not less than 20 days prior to the meeting, shall
notify each of its stockholders who was such on the record date for such meeting
with respect to shares for which appraisal rights are available pursuant to
subsections (b) or (c) hereof that appraisal rights are available for any or all
of the shares of the constituent corporations, and shall include in such notice
a copy of this section.  Each stockholder electing to demand the appraisal of
his shares shall deliver to the corporation, before the taking of the vote on
the merger or consolidation, a written demand for appraisal of his shares.  Such
demand will be sufficient if it reasonably informs the corporation of the
identity of the stockholder and that the stockholder intends thereby to demand
the appraisal of his shares.  A proxy or vote against the merger or
consolidation shall not constitute such a demand.  A stockholder electing to
take such action must do so by a separate written demand as herein provided.
Within 10 days after the effective date of such merger or consolidation, the
surviving or resulting corporation shall notify each stockholder of each
constituent corporation who has complied with this subsection and has not voted
in favor of or consented to the merger or consolidation of the date that the
merger or consolidation has become effective; or

          (2) If the merger or consolidation was approved pursuant to (S)228 or
253 of this title, the surviving or resulting corporation, either before the
effective date of the merger or consolidation or within 10 days thereafter,
shall notify each of the stockholders entitled to appraisal rights of the
effective date of the merger or consolidation and that appraisal rights are
available for any or all of the shares of the constituent corporation, and shall
include in such notice a copy of this section.  The notice shall be sent by
certified or registered mail, return receipt requested, addressed to the
stockholder at his address as it appears on the records of the

                                      -2-
<PAGE>
 
corporation.  Any stockholder entitled to appraisal rights may, within 20 days
after the date of mailing of the notice, demand in writing from the surviving or
resulting corporation the appraisal of his shares.  Such demand will be
sufficient if it reasonably informs the corporation of the identity of the
stockholder and that the stockholder intends thereby to demand the appraisal of
his shares.

          (e) Within 120 days after the effective date of the merger or
consolidation, the surviving or resulting corporation or any stockholder who has
complied with subsections (a) and (d) hereof and who is otherwise entitled to
appraisal rights, may file a petition in the Court of Chancery demanding a
determination of the value of the stock of all such stockholders.
Notwithstanding the foregoing, at any time within 60 days after the effective
date of the merger or consolidation, any stockholder shall have the right to
withdraw his demand for appraisal and to accept the terms offered upon the
merger or consolidation.  Within 120 days after the effective date of the merger
or consolidation, any stockholder who has complied with the requirements of
subsections (a) and (d) hereof, upon written request, shall be entitled to
receive from the corporation surviving the merger or resulting from the
consolidation a statement setting forth the aggregate number of shares not voted
in favor of the merger or consolidation and with respect to which demands for
appraisal have been received and the aggregate number of holders of such shares.
Such written statement shall be mailed to the stockholder within 10 days after
his written request for such a statement is received by the surviving or
resulting corporation or within 10 days after expiration of the period for
delivery of demands for appraisal under subsection (d) hereof, whichever is
later.

          (f) Upon the filing of any such petition by a stockholder, service of
a copy thereof shall be made upon the surviving or resulting corporation, which
shall within 20 days after such service file in the office of the Register in
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving or resulting corporation.  If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list.  The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the addresses
therein stated.  Such notice shall also be given by 1 or more publications at
least 1 week before the day of the hearing, in a newspaper of general
circulation published in the City of Wilmington, Delaware or such publication as
the Court deems advisable.  The forms of the notices by mail and by publication
shall be approved by the Court, and the costs thereof shall be borne by the
surviving or resulting corporation.

          (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled to
appraisal rights.  The Court may require the stockholders who have demanded an
appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.

                                      -3-
<PAGE>
 
          (h) After determining the stockholders entitled to an appraisal, the
Court shall appraise the shares, determining their fair value exclusive of any
element of value arising from the accomplishment or expectation of the merger or
consolidation, together with a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value.  In determining such fair value, the
Court shall take into account all relevant factors.  In determining the fair
rate of interest, the Court may consider all relevant factors, including the
rate of interest which the surviving or resulting corporation would have had to
pay to borrow money during the pendency of the proceeding.  Upon application by
the surviving or resulting corporation or by any stockholder entitled to
participate in the appraisal proceeding, the Court may, in its discretion,
permit discovery or other pretrial proceedings and may proceed to trial upon the
appraisal prior to the final determination of the stockholder entitled to an
appraisal.  Any stockholder whose name appears on the list filed by the
surviving or resulting corporation pursuant to subsection (f) of this section
and who has submitted his certificates of stock to the Register in Chancery, if
such is required, may participate fully in all proceedings until it is finally
determined that he is not entitled to appraisal rights under this section.

          (i) The Court shall direct the payment of the fair value of the
shares, together with interest, if any, by the surviving or resulting
corporation to the stockholders entitled thereto.  Interest may be simple or
compound, as the Court may direct.  Payment shall be so made to each such
stockholder, in the case of holders of uncertificated stock forthwith, and the
case of holders of shares represented by certificates upon the surrender to the
corporation of the certificates representing such stock.  The Court's decree may
be enforced as other decrees in the Court of Chancery may be enforced, whether
such surviving or resulting corporation be a corporation of this State or of any
state.

          (j) The costs of the proceeding may be determined by the Court and
taxed upon the parties as the Court deems equitable in the circumstances.  Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.

          (k) From and after the effective date of the merger or consolidation,
no stockholder who has demanded his appraisal rights as provided in subsection
(d) of this section shall be entitled to vote such stock for any purpose or to
receive payment of dividends or other distributions on the stock (except
dividends or other distributions payable to stockholders of record at a date
which is prior to the effective date of the merger or consolidation); provided,
however, that if no petition for an appraisal shall be filed within the time
provided in subsection (e) of this section, or if such stockholder shall deliver
to the surviving or resulting corporation a written withdrawal of his demand for
an appraisal and an acceptance of the merger or consolidation, either within 60
days after the effective date of the merger or consolidation as provided in
subsection (e) of this section or thereafter with the written approval of the
corporation, then the right of such stockholder to an appraisal shall cease.
Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery
shall be dismissed as to any

                                      -4-
<PAGE>
 
stockholder without the approval of the Court, and such approval may be
conditioned upon such terms as the Court deems just.

          (l) The shares of the surviving or resulting corporation to which the
shares of such objecting stockholders would have been converted had they
assented to the merger or consolidation shall have the status of authorized and
unissued shares of the surviving or resulting corporation.  (Last amended by Ch.
337, L. '92, eff. 7-1-92.)

                                   PART II.
                    INFORMATION NOT REQUIRED IN PROSPECTUS


Item 20.  Indemnification of Directors and Officers.

     Article VIII(d) of the Certificate of Incorporation of Intergraph permits
indemnification of directors and officers to the full extent permitted by the
Delaware General Corporation Law.

     Article IX of the Certificate of Incorporation of Intergraph eliminates a
director's personal liability for monetary damages for breaches of his fiduciary
duty, except for liability for: (a) breaches of the duty of loyalty to
Intergraph or its shareholders, (b) acts or omissions not in good faith or
involving intentional misconduct or knowing violations of the law, (c) the
payment of unlawful dividends or unlawful stock repurchases or redemptions, or
(d) transactions in which the director received an improper personal benefit.
Liability arising out of acts or omissions which occurred before the enactment
of Article IX are not covered by the provision.

     Article IX of the Certificate of Incorporation of Intergraph also
authorizes Intergraph to indemnify an officer, director, employee, or agent of
Intergraph for all expenses, liability, and losses incurred in connection with
any action, suit, or proceeding in which he is or was a party or is threatened
to be made a party by reason of the fact that he is or was an officer or
director of Intergraph, whether the basis of such proceeding is alleged action
in an official capacity as a director, officer, employee or agent, or in any
other capacity while serving as a director, officer, employee, or agent.  This
provision permits indemnification only upon a finding by the disinterested
directors or the shareholders that he acted in good faith and in a manner he
reasonably believed to be in, or not opposed to, the best interests of
Intergraph.  Article IX also authorizes Intergraph to advance litigation
expenses to an officer or director prior to the final disposition of the action.
The making of such advance is conditioned upon the officer or director giving
Intergraph an undertaking to repay the amount advanced if indemnification is
ultimately deemed unavailable.  If indemnification or advancement of expenses is
authorized, it will not exclude any rights to indemnification or advancement of
expenses which a director, officer, employee, or agent may have under a by-law,
agreement, board or shareholder resolution, or otherwise.  The indemnification
or advancement of expenses provided by Article IX will continue as to a person
who ceases to be a director, officer, employee, or agent, and inures to the
benefit of his heirs, executors, and administrators.

     Section 145 of the Delaware General Corporation Law permits indemnification
by Intergraph of any director, officer, employee or agent of Intergraph or
person who is serving or was serving at Intergraph's request as a director,
officer, employee or agent of another corporation or other enterprise, against
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement, actually and reasonably incurred by him in connection with the
defense of any threatened, pending or completed action (whether civil, criminal,
administrative or investigative), to which he is or may be a party by reason of
having been such director, officer, employee or agent, provided that he acted in
good faith and in a manner he reasonably


                                     II-1
<PAGE>
 
believed to be in or not opposed to the best interests of Intergraph, and, with
respect to any criminal action or proceeding, he had no reasonable cause to
believe his conduct was unlawful.  Intergraph also has the power under Section
145 to indemnify the persons identified above from threatened, pending or
completed actions or suits by or in the right of Intergraph to procure a
judgment in its favor by reason of the fact that such person was a director,
officer, employee or agent of Intergraph or is or was serving at the request of
Intergraph as a director, officer, employee or agent of another corporation or
enterprise against expenses actually and reasonably incurred by him in
connection with the defense or settlement of the action if he acted in good
faith and in a manner he reasonably believed to be in or not opposed to the best
interest of Intergraph, except that no indemnification can be made with regard
to any claim, issue or matter as to which the person has been adjudged to be
liable for negligence or misconduct in the performance of his duty to Intergraph
unless and only to the extent that the Delaware Court of Chancery or the court
in which the action was brought determines that the person was fairly and
reasonably entitled to indemnity.  Any indemnification (unless ordered by a
court) must be made by Intergraph only as authorized in the specific case upon a
determination that indemnification of the person is proper under the
circumstances because he has met the applicable standards of conduct.  The
determination must be made by the Board of Directors by a majority vote of a
quorum consisting of directors who are not parties to the action, or if a quorum
is not obtainable or, even if obtainable, a quorum of disinterested directors so
directs, by independent counsel in a written opinion, or by the stockholders.
Intergraph may pay the expenses of an action in advance of final disposition if
authorized by the Board of Directors in a specific case upon receipt of an
undertaking by the person to be indemnified to repay any such advances unless it
shall ultimately be determined that such person is entitled to be indemnified by
Intergraph as authorized by law.

     Article IX of the registrant's Bylaws provides for indemnification of the
registrant's directors, officers, employees or agents to the extent permitted by
Section 145 of the Delaware General Corporation Law.  Article IX of the
registrant's Bylaws further provides that the registrant may purchase and
maintain insurance on behalf of those persons described above as eligible for
indemnification for liability arising out of such person's duties or status with
the registrant whether or not indemnification in respect of such liability would
be permissible.

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of Intergraph
pursuant to the foregoing provisions, or otherwise, Intergraph has been advised
that in the opinion of the 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 Intergraph of expenses incurred or paid by a director, officer or
controlling person of Intergraph 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, Intergraph 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.

               (ii)  To reflect in the prospectus any facts or events arising
after the effective date of the registration statement (or the most recent post-

               (iii) To include any material information with respect to the

any material change to such information in the registration statement;     
              
          (2)  That, for the purpose of determining any liability under the

pursuant to paragraph (c) immediately preceding, or (ii) that purports to meet
the requirements of Section 10(a)(3) of the Act and is used in connection with
an offering of securities subject to Rule 415, will be filed as a part of an
amendment to the registration statement and will not be used until such
amendment is effective, and that, for purposes 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.       
         
     (f)  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
