of the provisions of this Agreement shall be binding unless made

          24.  No remedy referred to in this Agreement is intend
ed to be exclusive, but each shall be cumulative and in addition
to any other remedy referred to herein or otherwise available at
law or in equity.  The failure of either party at any time or
times to require performance of any provision hereof shall in no
manner affect the right, at a later time, to enforce such provi

ed in accordance with the substantive law of the State of Dela
ware.

the masculine, feminine or neuter, singular or plural, as the
identity of the person or persons may require.

          28.  This Agreement is being made and entered into

person as a third party beneficiary of this Agreement or other

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

          This Amendment No. 14 to the Software License Agreement
dated April 17, 1987 (this "Amendment"), is entered into this 2nd
day of May, 1994, by and between Intergraph Corporation
("Intergraph"), a Delaware corporation having its principal
office and place of business at 1 Madison Industrial Park,
Huntsville, Alabama 35894, and Bentley Systems, Incorporated
("BSI"), a Delaware corporation having its principal office and
place of business at 690 Pennsylvania Drive, Exton, Pennsylvania
19431.


                      W I T N E S S E T H:

          WHEREAS, the parties hereto entered into a Software
License Agreement dated April 17, 1987, and amended by prior
Amendments No. 1 through No. 13;
          WHEREAS, the parties hereto are parties to a Settlement
Agreement and Mutual General Release of even date herewith, which
is one of several agreements that collectively comprise the
definitive agreement among the parties in settlement of certain
litigation and arbitration proceedings pending between and among
them;

          WHEREAS, as part of the definitive agreement, the
parties hereto have agreed to enter into this Amendment to
further amend the terms of the Software License Agreement;

          WHEREAS, the parties now wish to establish the BSI
Comprehensive Support Plan as the basis for future MicroStation
support for End Users; and

          WHEREAS, the parties desire to terminate the Software
License Agreement on December 31, 1994, after which time the
Software License Agreement will be succeeded by a new
Distribution Agreement between the parties.

          NOW, THEREFORE, intending to be legally bound hereby,
the parties hereto agree as follows:


                    ARTICLE I.  DEFINITIONS

          The following words, terms, and phrases shall in this
Agreement have the following meaning:

          1.01  "Software Reissue" means the distribution or
license of copies of the Licensed Programs by Intergraph for use
by an existing End User on a different category of workstation
architecture (as classified by Intergraph when the End User
license was issued) than that originally used by such End User
for the Licensed Programs, where such user has relinquished the
original license and destroyed all copies of original
documentation and original software, and where Intergraph has not
previously paid to BSI a royalty for such transaction.  The term
Software Reissue shall not apply to upgrades to the Clipper
workstation issued by Intergraph pursuant to Paragraph 6 of
Amendment No. 1 to the Software License Agreement.
                               
                               
                           ARTICLE II

          2.01      Non-Exclusivity

               (a)  Intergraph and BSI agree that the license
granted to Intergraph in the April 17, 1987, Software License
Agreement is non-exclusive as of the date hereof.  This Amendment
shall be effective on the date first set forth above, and shall
expire with the termination of the Software License Agreement on
December 31, 1994, to be succeeded January 1, 1995 by the
Distribution Agreement between the parties.

               (b)  BSI agrees that through December 31, 1994,
BSI will not distribute end-user products other than MicroStation
Review (all platforms) and MicroStation Field under the terms set
forth below:

                    (i)  BSI shall have the right to distribute
MicroStation Review (all platforms) and MicroStation Field only
to existing CSP subscribers and only direct and without
advertising such products;

                    (ii) BSI will provide for product
registration;

                    (iii)     the U.S. List price and royalty for
MicroStation Field shall be *** and ***, respectively; and

                    (iv)  BSI may compensate a CSP Partner in an
amount less than *** of the list price for sales
of MicroStation Review and MicroStation Field to sites served by
the CSP Partner.

               (c)  Notwithstanding subparagraph (b) above,
during 1994, BSI shall have the right to:

                    (i)  enter into agreements pursuant to which
it grants rights to distribute MicroStation "engine" software
(which does not make available to users the MicroStation user
interface as such) to developers for incorporation and bundled
distribution with their applications for use by third parties;
and

                    (ii) distribute software for educational
purposes to training centers, schools and students at nominal
cost, pursuant to Paragraph 6.08 of the Business Relations
Agreement of even date herewith.


          2.02  Alternate Platform Upgrades.  Intergraph shall
not market, advertise, offer for sale, sell, or renew existing
agreements for (a) Alternate Platform Upgrades without charge or
at a discount conditioned upon the purchase of maintenance
services, or (b) maintenance services at a discount or without
charge conditioned upon the purchase of Alternate Platform
Upgrades. The term "Upgrades" in this paragraph shall mean
enhancements, modifications, additions and substitutions to the
Licensed Programs which are offered normally at additional
charge.  The term "Alternate Platforms" means platforms other
than Intergraph Clipper Workstation or Sun Microsystems SPARC
workstations sold or serviced by Intergraph Corporation.


          2.03  Reissue Royalties.
                
                 (a)  Within thirty (30) days of the date of
  this Agreement, Intergraph shall pay to BSI ***
  of the royalties payable by Intergraph to BSI pursuant
  to Section 5.1 for each copy of the Licensed Programs
  distributed by Intergraph as a Software Reissue from January
  1, 1993, until March 31, 1994. Thereafter, Reissue Royalties
  shall be due and paid quarterly through December 31, 1994, at
  a rate of *** of the royalty rate specified in
  Section 5.1 for each copy.

               (b)  Intergraph shall have no obligation to pay a
royalty to BSI for a Software Reissue made by Intergraph pursuant
to its existing "Phoenix program" (in which an existing Clipper
workstation is physically upgraded by installing an Intel
processor within such workstation), provided that the
MicroStation License for the Intel processor is immediately
placed under CSP Maintenance.

          2.04  Termination.  The following provision shall
replace the termination for cause provisions in Section 13:

          (a)  This Agreement may be terminated for a material
breach of this Agreement, but only pursuant to the procedures set
forth in this Section 2.04.  If either party believes that a
material breach of this Agreement has occurred, that party (the
"aggrieved party") must first give the other party written notice
of termination specifically identifying the breach or breaches
alleged to have occurred.  The party receiving written notice
shall then have thirty (30) days in which to cure such breach or
breaches.  If within the thirty (30) days the breach or breaches
are not cured to the satisfaction of the aggrieved party, then
the aggrieved party may file a Demand For Arbitration seeking a
determination of whether a material breach has occurred.  Such
Demand for Arbitration shall be determined in accordance with the
procedures set forth in Section 14.13 hereof.  Except for claimed
breaches involving payment obligations where the paying party has
failed to make timely payment of at least fifty percent (50%) of
the disputed amount to the other party, neither party may
withhold its performance under this Agreement unless and until
there has been a final determination pursuant to Section 14.13
that a material breach has occurred.  The parties agree to take
all reasonable steps necessary to expedite a final determination
in accordance with Section 14.13.

          (b)  The parties hereto specifically agree and
acknowledge that subparagraph (a) sets forth an essential and
unique provision of this Agreement and that the failure of either
party strictly to adhere to the terms of subparagraph (a) above,
including unilaterally withholding its performance under this
Agreement, will cause irreparable harm to the other party.  The
parties further specifically agree and acknowledge that either
party shall be entitled to injunctive relief to enforce strictly
the terms of subparagraph (a).

          (c)  If BSI has withheld performance by failing to
provide to Intergraph any error correction change to the Licensed
Programs, which change has been provided by BSI to any third
party, then Intergraph shall have the right to withdraw and use
source code under the terms of Section 10.6.

     Intergraph will continue to have the rights set forth in
this Section 2.04(c) until either (1) BSI resumes performance in
accordance with the terms of this Agreement or (2) there is a
final determination pursuant to Section 2.04(a) that Intergraph
has committed a material breach of this Agreement, whichever
first occurs.

          2.05  Term.  Section 12.1 of the Software License
Agreement shall be amended to read as follows:

                         12.1  Duration -- Unless
               terminated as provided in Section
               13 as amended by Section 2.04 of
               Amendment No. 14, this Agreement
               shall remain in force until
               December 31, 1994, to be succeeded
               January 1, 1995, by the
               Distribution Agreement between BSI
               and Intergraph.

          2.06  CSP.  In furtherance of establishing the BSI
Comprehensive Support Program ("CSP") as the basis for future
MicroStation support for End Users:

               (a)  There shall be no minimum contract value
required for  CSP after the date of this Agreement.  The last
sentence of Section 7.1 of the Software License Agreement is
hereby deleted, and shall have no further force or effect.

               (b)  BSI shall have the right to offer CSP to end
users directly or indirectly.

          2.07  CSP Support CD's.

               (a)  Intergraph shall have the right to distribute
the quarterly CSP support CD's (including the foreign language
translations of resources contained therein) as an upgrade to End
Users that have not contracted for CSP maintenance services.

               (b)  The parties agree that Section 5.1 is hereby
revised to provide for a list price of *** for each quarterly
CSP CD and a royalty of *** payable by Intergraph to BSI for each
such CD distributed by Intergraph to End Users.

          2.08  Time Extensions.

               (a)  The parties agree that the April 30, 1994
date contained in Section 5.1(g) of the Software License
Agreement shall be revised to June 30, 1994.

               (b)  The parties agree that the June 30, 1994 date
set forth in Section 5.1(e) of the Software License Agreement
shall be revised to December 31, 1994.

          2.09 Minimum Obligations for Certain Platforms.  The
following language shall be added to Section 5.1:

               Licensor and Licensee agree to offer MicroStation
               Version 5 on Dec Alpha NT, IBM RS 6000 and SGI
               platforms.  Licensee guarantees to Licensor a
               Minimum Number of royalty unit sales on each of
               these platforms between the initial date of
               availability of each such version and December 31,
               1994.  To the extent that Intergraph has failed to
               fulfill the Minimum Number of sales with actual
               licenses, Intergraph shall remit to BSI the
               balance of its commitment hereunder with its
               fourth quarter 1994 royalty payment for the
               Licensed Programs.  Such payment of the balance
               shall be treated as prepaid purchases as to such
               product.  The term "Minimum Number" shall mean,
               with respect to each such version, the number of
               calendar days between the date of its initial
               availability from BSI and December 31, 1994,
               multiplied by 1.39.

          2.10  Superseded Provisions.  The parties acknowledge
and agree that Section 9.1 of the Software License Agreement
shall not be construed to prohibit activities of BSI permitted
under the Business Relations Agreement.

          2.11  Royalty Report.  Intergraph shall include in the
reports accompanying its quarterly royalty payments an
itemization by platform and country for sales or licenses of each
product (including Intergraph TD products separate from other
PC's or Intergraph Clipper workstations).  Intergraph shall
itemize by product traded or migrated both trade-up and migration
programs in such royalty reports.

          2.12  Migration.  Licensees of MicroStation PC shall be
entitled to migrate to the forthcoming "Chicago" (DOS 7/Windows
4) operating environment at *** charge.  Licensees of
MicroStation PC shall be entitled to migrate to the Windows NT
platform at *** charge at any time after upgrading to
Version 5.  Licensees of MicroStation SPARC shall be entitled to
migrate to Solaris 2 at *** charge at any time after
upgrading to Version 5.

          2.13  Product Registration.  Intergraph shall have the
option to retain responsibility to register End Users of Version
5 of MicroStation or to assign this function in its entirety to
BSI by furnishing written notice to BSI of such assignment.

                2.14  Product Kitting.  BSI may do product
kitting for BSI's CSP and ISD customers and other persons to whom
BSI may distribute software under the terms of this Amendment.

          All other terms and conditions of the Software License
Agreement, as amended, shall remain unchanged.

June 13, 1990



Mr. Al Yocom
Computer Services Manager
Department of Transportation
700 Broadway Avenue, East
Pierre, South Dakota   57501

Dear Al:

Since I was involved in the previous generation of policy
regarding MicroStation, I have chosen to answer your letter this
time also.  In giving you our position, I have coordinated it
with Bentley Systems.

Since my letter of November 1988, I think the following
significant events are worth noting:

1)   MicroStation has been ported to the Macintosh and is
     deliverable.

2)   MicroStation Release 4.0 will be available later this year
     for the PC MS-DOS environment and  will take advantage of the
     extended features of the 386 and 486 Intel processor.  This
     product   will not be available on the lower level PC products.
     That same functionality level (Release 4.0)  will be available on
     the Intergraph CLIPPER platform in the first quarter of 1991.

3)   MicroStation on CLIPPER has become the base product for our
     AEC and Mapping application   products.
  
4)   Intergraph has decided that MicroStation and the IGDS format
     are no longer to be considered     proprietary and we are in the
     process of making that announcement.  As you know, there were
     previous restrictions regarding interfacing to that file format;
     all those restrictions are now     lifted.

5)   OS2 has failed to live up to its early promises and has not
     been a significant force in the    computer industry to date; and
     the new release of Windows for MS-DOS is probably going to
     result in that environment being the predominant PC environment
     for the next few years.

6)   UNIX has evolved into two fundamental camps with some
     differences even within the camps;      however, the application
     program interface standards make portability easier in the UNIX
     environment.

7)   There is an effort underway at Bentley Systems to convert
     MicroStation such that it is more easily     ported to the
     various UNIX platforms.  The status of that effort is that there
     is preliminary      release on the VAX-Station, but no production
     product is available now or in the near future.

Therefore, our commitment to JDTF is that Intergraph/Bentley
Systems will keep MicroStation current as an open software
platform on the CLIPPER-based Intergraph products and under MS-
DOS on the PC for the indefinite future.  We are approaching the
time in which we must make a decision as to which other platform
we will support in the summer of 1991.  The three choices we are
considering are:  OS2. the Sun SPARC platform and the IBM 6000
platform.  We would welcome a dialogue in the next six weeks that
would participate in the decision regarding which of these three
platforms we will offer.  There is a commitment on our part to do
this; it is merely a matter of deciding which of these comes
first.

I value both my and Intergraph's relationship with the JDTF and
look forward to being able to provide your MicroStation as a
basis for your future development.  If I can do anything to
further clarify this position or adjust it to meet your
requirements, please contact me.




Sincerely,



Jim Meadlock
CEO

Products on Alternate Platforms.  Intergraph and BSI shall use
their best efforts to accomplish this objective.

          2.02  Encouragement to Subscribe.  In furtherance of
the parties' mutual objective to establish MicroStationCSP as the
primary support program for MicroStation Products, Intergraph

offered by Intergraph to subscribe instead to MicroStationCSP.

          2.03  Promotion.  Intergraph, upon depletion of current
inventory of Product Kits, hereafter shall not include any
information regarding any support programs for MicroStation
Products other than MicroStationCSP in Alternate Platform kits.

such software and documentation relating thereto.

          2.05  Restrictions on Alternate Platform Support
Service.

               (a) Intergraph shall not market, advertise, offer

upon the purchase of Upgrades.

               (c)  In the event that Intergraph has, prior to
March 30, 1994, made any proposal to a third party account for
support services which would be prohibited under sub-paragraph
2.05 (b) above  and remained outstanding as of March 30, 1994,
then Intergraph shall make best efforts to convert said account
to MicroStationCSP; however, if this is not possible, Intergraph
will be allowed to honor said quote.


                          ARTICLE III
                      RATES; COMPENSATION

ble for the invoicing and collection of all subscription fees
from all Subscribers to which it has sold MicroStationCSP.

          3.03  Compensation to BSI for MicroStationCSP.

latest renewal, as to the applicable country of service, to each
extant individual contract under which Intergraph has sold
MicroStationCSP support service, pro-rated at one-twelfth of the
annual rate per month, and then by multiplying the aggregate of
such amounts, in the currency of each country, by BSI's
compensation rate hereunder.  Such BSI compensation rate shall be
*** of such aggregate MicroStationCSP fees
earned during 1994, and *** of such aggregate
MicroStationCSP fees earned thereafter.  Intergraph shall remit
such earned subscription fees to BSI in accordance with Paragraph
3.05 hereof.


          3.04  Compensation To BSI for Other Alternate Platform
Support.  Alternate Platform support fees are deemed to be earned
based on proration of the periodic charges for contracts in

Intergraph shall pay to BSI *** of the Net
Revenues that it earns during 1994 and *** of
the Net Revenues that it earns on or after January 1, 1995.  The

quarter.  Amounts due in currencies other than U.S. dollars will
be converted and paid in U.S. dollars at the mid-market exchange
rates published in the Wall Street Journal on the day before such
payments are due.  Intergraph bears all responsibility and risk
for collections from end users.

               (b)  Intergraph shall submit with each royalty
payment a full report setting forth the identity of each Sub
scriber and each site, the contract number, the type of support
service, the period of coverage, and the fees earned from such
subscriber.

          3.06  Records; Audit.  Intergraph shall maintain
sufficient and accurate records of all revenues and deductions
relating to its furnishing of MicroStationCSP and Alternate
Platform support service to permit the computation of the sums
due hereunder to BSI.  Intergraph shall, upon ten (10) days
advance written notice by BSI, but not more frequently than once
each calendar year, permit reasonable inspection of such records
by BSI or its accountants at the offices of Intergraph during

          3.07  Taxes.  Each party shall be responsible and shall
pay any and all taxes that are due and payable with respect to

                 BENTLEY SYSTEMS, INCORPORATED
                      OEM SOFTWARE LICENSE

                      TERMS AND CONDITIONS
                      --------------------

I.   DEFINITIONS.


In this Agreement, the terms:

     (a) "Source Code" means a human readable form of computer
program showing the computer language instructions comprising the
program, from which Object Code can be produced, in which the
program logic may be deduced by a human being, and from which a
printed listing can be made by processing it with a computer.

     (b) "Object Code" means a form of computer program resulting
from the compilation or other processing of Source Code by a
computer into machine language or intermediate code, and thus is
a form that would not be convenient to human understanding of the
program logic, but which is appropriate for the construction and
linking of binary executable modules, as well as for the
execution by a computer.

     (c) "Licensed Programs" or "Run Time Engine"  means
MicroStation Version 5 Runtime Engine software in Object Code
only as specified in Exhibit F, and all modifications and
enhancements thereof, if any.

     (d) "Use" means copying any portion of the Licensed Programs
into a computer and/or transmitting it to a computer for
processing of the machine instructions or statements contained in
the Licensed Programs.

     (e) "License" means the non-exclusive, non-transferable
right of Licensee to use, reproduce and distribute the Licensed
Programs integrated with a Licensee Accepted Application and
subject to the provisions of this Agreement.

     (f) "Supported Environments" shall mean those set forth in
Exhibit F.

     (g) "Derivative Work" means a revision, modification,
translation, abridgement, condensation or expansion of a computer
program, or any other form in which such program may be recast,
transferred or adapted, which if prepared without the consent of
BSI would constitute a copyright infringement.

     (h) "Intergraph PointStation Application" shall mean an
Intergraph product in which the Licensed Programs, or any part
thereof, are integrated with an Accepted Application for
execution by an End User on a Supported Environment.  Intergraph
PointStation Applications may only run other applications that
are themselves "Accepted Applications" and then only if they are
invoked at the beginning of the session. Intergraph PointStation
Applications may not be used on a server to run other
applications.

     (i) "End User License Agreement" means the standard
Intergraph written End User License Agreement, in the form
attached hereto as Exhibit A, which will be entered into between
Licensee and an End User to enable the End User to lawfully use
Licensee's Intergraph PointStation Application on the platform
specified in the Agreement.

     (j) "Intellectual Property Rights" means all rights held by
any Party to any item of Intellectual Property.

     (k) "Significant Value Added" means vertical application
software that provides significant functions not available
through the Licensed Programs alone.  Such application software
should combine the functionality of the Licensed Programs in
novel ways, enhance the basic Licensed Program's capabilities,
and otherwise provide "higher" level functions.

     (l)  An "Accepted Application" shall mean an application
that (except to the extent that BSI and Intergraph mutually agree
in writing) meet the criteria in subparagraphs (i), (ii), and
(iii) below, and meet the criteria in  either of subparagraphs
(iv) or (v) below:

          (i)  It must have been developed by Intergraph (but may
contain third-party content comprising less than 50% of the
object code), or Intergraph must be in possession of the
exclusive distribution license for the United States.

          (ii) It must prerequisite (that is, technically require
for its operation) MicroStation V5.

          (iii)     It must have been, and must continue to be,
actively marketed and sold as a product to End Users and
Resellers for operation with MicroStation V5 (even if also
available in the form of an Intergraph PointStation Application).

          (iv) It must be or must have been actively marketed and
sold by Intergraph as of March 30, 1994 at a U.S. list price
exceeding One Thousand Dollars ($1,000.00).  Notwithstanding the
foregoing sentence, the *** are
deemed to meet the criterion in this section (iv). In no event
will any member of the existing ***
family of products be considered an Accepted Application.

          (v)  BSI and Intergraph must agree that it demonstrates
"Significant Value Added", as to its Intergraph value content, to
an extent at least on the order of existing Intergraph
applications meeting the criteria (i) through (iv) above.  For
products solely developed by Intergraph (or for which Intergraph
has the exclusive worldwide distribution license), the bona fide
U. S. list price shall be considered to measure the Intergraph
value content.


II.  OWNERSHIP OF LICENSED PROGRAMS.

Licensee acknowledges and agrees that:

     (a) Title to and all rights of ownership in the Licensed
Programs, and all copies of all or any part thereof, are and
remain with BSI;

     (b) The Licensed Programs contain and are comprised of BSI's
trade secrets and other proprietary, confidential information;
and

     (c) Licensee will not sell, lease, lend, transfer, assign,
hypothecate, or otherwise distribute the Licensed Programs except
as expressly authorized in this Agreement.



III. LICENSE.

     (a) BSI grants to Licensee a non-exclusive, non-
transferable, world-wide license to use the Licensed Programs
solely for the purpose of creating Intergraph PointStation
Applications, as defined herein, and to distribute Intergraph
PointStation Applications, subject to the condition that in order
to qualify for integration with the Licensed Programs to create
an Intergraph PointStation Application, the application must be
an Accepted Application hereunder.

     (b) Title to the Licensed Programs shall remain in BSI at
all times.  Licensee does not have, and shall not attempt to
obtain, any title to BSI's Licensed Programs or Intellectual
Property.

     (c) Licensee is acquiring an Object Code Version of the
Licensed Programs, and thus shall not have the right to modify or
adapt the Licensed Programs for incorporation into Intergraph
PointStation Applications.

     (d) Certain Transactions.  For any Intergraph PointStation
Application as to which the list price is at any time less than
BSI's list price for MicroStation Draft, then notwithstanding the
terms of Section IV and Exhibit B hereto, the royalty payable to
BSI for distribution of each copy of such Intergraph PointStation
Application during such time shall be equal to the purchase price
which Intergraph at such time pays to BSI for Product Kits of
MicroStation Draft pursuant to the Distribution Agreement of even
date herewith or, if lapsed, the final such price payable
thereunder at the time of such lapse.  Intergraph's discount
schedules and policies (for end users, resellers, and
distributors) for Intergraph PointStation applications, shall be
consistent with its then-existing discount schedules and policies
for its other software products.

     (e) Internal Use.  BSI hereby grants to Licensee a personal,
non-exclusive, and non-transferable license to use the Licensed
Programs on any of its internal systems for the sole purpose of
creating Intergraph PointStation Applications, without payment of
any royalty.

     (f) Demonstrations.  BSI hereby grants to Licensee a
personal, non-exclusive, and non-transferable license to use the
Licensed Programs without fee or royalty solely for
demonstrations of Intergraph PointStation Applications to
existing or potential end-users, and for training and support.

     (g) Loan Copies.  As part of the demonstration to potential
end-users, Licensee shall be allowed to loan copies of Intergraph
PointStation Applications without the payment of a royalty or fee
under this Agreement.  All such loans will be limited to
evaluation purposes, and copies used for productive purposes
shall be specifically excluded from this provision.  Licensee
agrees to use its best judgment in the loaning of copies of
Intergraph PointStation Applications.

IV.  LICENSE FEE, PAYMENT AND TAXES.

     (a) As compensation for the license to use the Licensed
Programs as set forth in this Agreement, Licensee shall pay to
BSI the royalties and other fees set forth in Exhibit B.  Royalty
payments required as documented in Licensee's records and
maintained in accordance with Section V hereof, shall be due
within thirty (30) days after the end of each calendar quarter
for copies of any Intergraph PointStation Application distributed
by Licensee during such calendar quarter.  In no event shall
Licensee be entitled to a refund of any License Fees or prepaid
royalties, except in the case of return by End Users within 90
days.

     (b) All payments provided for in this Agreement are
exclusive of, and Licensee shall pay, all taxes, customs duties,
insurance, shipping and other charges.  Payments made to BSI
shall be in U.S. Dollars.

     (c) If any payment, or any other sum due from Licensee under
this Agreement, should become overdue, a late payment charge of
one and one-half percent (1.5%) per month on the overdue balance
shall be paid to BSI by Licensee.  Such late payment charge shall
be due and payable upon request from BSI.

V.   RECORD KEEPING AND REPORTS.

     (a) Licensee agrees to maintain reasonable royalty records
relating to all Intergraph PointStation Applications licensed
hereunder.  Licensee shall prepare and submit summary quarterly
reports to BSI no later than thirty (30) days following the last
business day of each calendar quarter, which reports must specify
the name, and quantities of all Intergraph PointStation
Applications licensed to End Users, distributors, or resellers
during such quarter.

     (b)  Licensee agrees to allow an independent certified
public accountant, or other audit professional, selected by BSI
and acceptable to the Licensee to audit and analyze appropriate
accounting records of Licensee, including the Registration
database described in Section VII(b) hereof, to ensure compliance
with all terms of this Agreement.  Any such audit shall be
permitted by Licensee within ten (10) days of Licensee's receipt
of a written request of BSI to audit, during normal business
hours.  The cost of such an audit will be borne by BSI unless a
material discrepancy indicating inadequate record keeping or that
additional license or royalty fees are due to BSI is discovered,
in which case the cost of the audit shall be borne by Licensee.
A discrepancy shall be deemed material if it involves an
adjustment of more than Five Thousand Dollars ($5,000.00) in
favor of BSI.  Audits shall not interfere unreasonably with
Licensee's business activities.

VI.  TRADEMARKS AND COPYRIGHT NOTICES.

     (a) The trademarks and trade names under which BSI markets
any of its products are the property of BSI.  This Agreement
gives Licensee no rights therein, except the restricted license
to reproduce such trademarks and trade names in any authorized
reproduction of an Intergraph PointStation Application, provided
that BSI is referenced as the owner of the trade name or
trademark, as specified in EXHIBIT C.  Licensee may not market
the Licensed Programs alone or in any form other than in an
Intergraph PointStation Application, as defined herein.
Licensee's Intergraph PointStation Applications may be marketed
under any name of Licensee's choosing, however, such Intergraph
PointStation Application shall be designated as containing BSI's
Licensed Programs, which shall be acknowledged in accordance with
EXHIBIT C attached hereto. Intergraph may refer to Intergraph
PointStation Applications as "MicroStation Engine Powered" or
"MicroStation Engine Based" but may not use the word
"MicroStation" in any other reference to Intergraph PointStation
Applications (e.g. "MicroStation Powered" or "MicroStation
Based") or in any manner that otherwise implies that a license
for MicroStation is provided with the Intergraph PointStation
Application.


     (b) Licensee agrees to use the trademark, trade name and
copyright notices of the Licensed Programs and any documentation
in connection with its advertisement and distribution of any
Intergraph PointStation Application.  Licensee shall request and
use reasonable diligence to ensure compliance hereto by all
Licensee's distributors and dealers.  Trademark, trade name and
copyright notices placed by Licensee shall read as specified in
EXHIBIT C, attached hereto.  BSI retains the right to specify the
reasonable quality and standards of all materials upon which a
BSI trademark or trade name is used.  In the case of a failure by
Licensee to adhere to such standards of quality such failure
shall be grounds for BSI to terminate Licensee's right to the use
of such trademark or trade name in such cases.

VII. LICENSED PROGRAM REPRODUCTION AND SERIALIZATION.

     (a) Licensee is authorized to reproduce the Licensed
Programs for inclusion in an Intergraph PointStation Application
only at the location of its principal office specified on the
first page of this Agreement.  A subsidiary or affiliate of
Licensee, which has been authorized by Licensee to reproduce its
Intergraph PointStation Applications, shall have the right to
reproduce the Licensed Programs only under the condition that any
reproduction site other than Licensee's principal office must be
specifically authorized by BSI to reproduce the Licensed Programs
for inclusion in Intergraph PointStation Applications, which
authorization shall not be unreasonably withheld.

     (b) Licensee will assign a unique serial number to each copy
of an Intergraph PointStation Application.   Licensee will also
require each End User of an Intergraph PointStation Application
to agree to an End User Software License Agreement in the form
attached hereto as Exhibit A and to register with Licensee, and
Licensee will maintain a Registration database showing the serial
number, registered owner, and date of acquisition  of each copy
of an Intergraph PointStation Application.

VIII.     DISTRIBUTION AND EXPORT RESTRICTIONS.

     (a) Licensee shall include an End-User License Agreement in
the form attached hereto as Exhibit A with each copy of an
Intergraph PointStation Application distributed to End Users.
Licensee shall use its best efforts to obtain either directly or
through its distribution channels, the signature of the end user
on such End User License Agreement.  Breaking a shrink wrap seal
will be considered equivalent to an end user signature.

     (b) Licensee shall take reasonable steps to ensure that each
intermediate entity in its chain of distribution to the final end
user respects BSI's copyrights, trade names and trademarks,
complies with the  licensing and reporting requirements of this
Agreement, and makes no unauthorized copies of the Licensed
Programs or Intergraph PointStation Application.

     (c) End Users may use Intergraph PointStation Applications
for the term and in the manner provided for in the End User
License Agreement.  End User rights and obligations set forth
therein will survive any termination of the relationship between
Licensee and BSI.

     (d) Licensee warrants and hereby gives written assurance to
BSI that it will do all things necessary to comply with the
current United States Export Administration and any other United
States laws and regulations as they apply to the Licensed
Programs, Intergraph PointStation Application, and all other
things delivered to, or derived from things delivered to,
Licensee under this Agreement (all and any part of such things
collectively referred to as "Technical Data").  Licensee agrees
to comply with these laws and regulations as they apply at the
time of exporting said Technical Data, as they may be revised and
modified at various times.


IX.  PATENTS AND COPYRIGHTS.

     (a) BSI warrants

          (i)  that it is the owner of the Licensed
               Programs, including all intellectual property
               rights therein under copyright, patent, trademark,
               trade secret, and other applicable law;

         (ii)  that the Licensed Programs do not
               infringe or otherwise violate any copyright,
               patent, or trade secret of any third-party; and

        (iii)  that as of the date hereof it has not
               received notice of any claim from a third-party
               that the Licensed Programs infringe intellectual
               property rights of any third-party.

     (b) BSI will defend any action brought against Licensee to
the extent that it is based upon a claim that the unmodified
Licensed Programs furnished hereunder and used within the scope
of the license granted hereunder, infringe a patent or copyright
or misappropriate a trade secret.  BSI will pay resulting costs,
damages and legal fees finally awarded against Licensee in any
such action, which are attributable to such claim provided that
(i) the Licensee notifies BSI promptly in writing of any such
claim and (ii) BSI has sole control of the defense of any such
claim and all related settlement negotiations.

     (c) Should the Licensed Programs become, or be likely to
become, in BSI's opinion, the subject of a third-party claim of
infringement of copyright or patent, BSI may procure for Licensee
the right to continue using the Licensed Programs, or replace or
modify them to make them non-infringing and functionally
equivalent to the Licensed Programs.  BSI shall have no liability
for, and Licensee shall indemnify and hold BSI harmless from and
against any claim based upon (i) use of other than a unaltered
release of the Licensed Programs or (ii) use, operation or
combination of the Licensed Programs with non-BSI programs or
data if such infringement would have been avoided but for such
use, operation or combination.

     (d) This Section IX states the entire liability of BSI with
respect to infringement of copyrights, patents, or other
intellectual property rights.

X.   WARRANTY, SUPPORT AND MAINTENANCE.

     (a) If Licensee finds what it believes to be a Deficiency
per Exhibit G, which materially affects performance, and provides
BSI with a written report, BSI will either use reasonable efforts
to promptly correct, at no cost to Licensee, any such errors or
failures, or at its discretion, allow Licensee to loan copies of
MicroStation Version 5 for a particular application, solely in
accordance with the procedure set forth in Exhibit G hereof.
This is Licensee's sole and exclusive remedy for breach of any
express or implied warranties hereunder, other than the warranty
against infringement specified in Section IX hereof.  BSI's
warranty and obligations shall extend so long as Licensee is
current on its support payment obligations specified in Exhibit
D.  BSI's warranty and obligation is solely for the benefit of
Licensee, which has no authority to extend this warranty to any
other person or entity.  BSI MAKES NO WARRANTY THAT ALL ERRORS OR
FAILURES WILL BE CORRECTED.

     (b) BSI agrees to provide to Licensee the support defined in
Exhibit D attached hereto, and Licensee agrees to pay for such
support as specified therein.

     (c) Licensee is solely responsible for all magnetic media
and other program materials provided to End Users and for passing
on to its distributors, dealers and End Users all maintenance
material.  These responsibilities may be performed at Licensee's
discretion, but in no event shall BSI provide any of these
services.  Licensee is solely responsible for all verbal and
written contact with the End Users of its Intergraph PointStation
Applications including (a) software maintenance including patches
and updates; and (b) software support including operational
instruction, problem reporting and technical advice.

     (d) EXCEPT AS PROVIDED IN SECTION (a) HEREIN, ALL WARRANTIES
(INCLUDING BUT NOT LIMITED TO THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE) AND
REPRESENTATIONS EXPRESSED OR IMPLIED BY STATUTE, COMMON LAW, OR
OTHERWISE ARE HEREBY EXCLUDED.

XI.  CONFIDENTIAL INFORMATION.

     (a) The Licensed Programs, and all information which is
provided to Licensee hereunder is confidential, including without
limitation, drawings, Object Code, Source Code, computer program
listings, techniques, algorithms and processes and technical and
marketing information ("Confidential Information") and shall be
treated confidentially by Licensee, its employees and
representatives and shall not be disclosed by Licensee without
BSI's prior written consent.  Information shall not be considered
to be Confidential Information if it (a) is already or otherwise
becomes publicly known through no act of the receiving party; (b)
is lawfully received from third-parties subject to no restriction
of confidentiality; or (c) can be shown by the receiving party to
have been independently developed by it prior to such disclosure.

     (b) Licensee shall not copy, reproduce, remanufacture, or
disassemble the Object Code or in any way duplicate all or any
part of the Confidential Information, including translating it
into another software language, except in accordance with the
terms and conditions of this Agreement.

XII. LIMITATION OF LIABILITY.

     (a) In no event shall BSI be liable for any loss of profits,
loss of business, loss of use or of data, interruption of
business, or for indirect, special, incidental or consequential
damage or injury, direct or indirect, of any kind, whether under
this Agreement or otherwise.  In no case will BSI be liable for
any representation or warranty made to any third party by
Licensee, any agent for Licensee, or any distributor or dealer or
other person or entity in the distribution chain.

     (b) Notwithstanding anything in this Agreement to the
contrary, the entire liability of BSI to Licensee for damages
concerning performance or nonperformance by BSI or in any way
related to the subject matter of this Agreement and regardless of
whether the claim for such damages is based in contract or in
tort, shall not exceed the amount of payments made hereunder by
Licensee to BSI.

XIII.     TERM OF AGREEMENT AND TERMINATION.

     (a) The term of this Agreement shall commence on the date
executed by BSI and shall continue unless earlier terminated as
provided in this section or otherwise rightfully terminated.
Notwithstanding the foregoing, Licensee may not distribute
Intergraph PointStation Applications before January 1, 1995.
     (b) BSI may terminate this Agreement forthwith and all
rights and licenses granted hereunder if Licensee materially
breaches this Agreement, and if such breach is not cured within
thirty (30) days after written notice of the breach.

     (c) Notwithstanding any other provision of this Agreement,
the occurrence of any of the following events shall, at the
option of BSI, constitute an event of material breach under this
Agreement entitling BSI to terminate this Agreement forthwith:

          (i)  If a petition or action shall be filed
               or taken by or against Licensee under any law
               dealing with insolvency, bankruptcy or suspension
               of payment;

         (ii)  If a Receiver is appointed over the
               assets or undertaking of Licensee (or any part
               thereof);

        (iii)  If Licensee enters into a deed or
               arrangement or makes an assignment for the benefit
               of creditors; or

         (iv)  If Licensee ceases to function as a
               going concern or an order is made or a resolution
               passed to that effect except for the purposes of
               amalgamation or reorganization.

Licensee shall notify BSI immediately upon the occurrence of any
of the foregoing events.

     (d) The obligations of Licensee in Section XI hereunder

Intergraph PointStation Applications and shall promptly return to
BSI and make no further use of the Licensed Programs and other
materials provided to Licensee under this Agreement.

     (e) This Agreement is executory in nature and so long as
Licensee has any continuing obligations hereunder, BSI shall be
entitled to protect the Licensed Programs and master reproduction
sets of the Licensed Programs from breaches of this Agreement.
BSI reserves the right to repossess, after a thirty (30) day
notice period in which Licensee fails to cure any such material
breach, the Licensed Programs and master reproduction sets.  This
right shall continue to subsist notwithstanding the termination
of this Agreement and is without prejudice to any accrued rights
of BSI hereunder.

XIV. GENERAL.

     (a) In the event that any one or more of the provisions of
this Agreement shall be found to be illegal or unenforceable,
then notwithstanding, this Agreement shall remain in full force
and effect, and such term or provision shall be deemed severed.

     (b) Neither party's right to require performance of the
other party's obligations hereunder shall be affected by any
previous waiver, forbearance, or course of dealing.

     (c) This is a License Agreement.  No agency, partnership,
joint venture or other joint relationship is created hereby and
neither Licensee nor Licensee's agents have any authority of any
kind to bind BSI in any respect whatsoever.

     (d) Notwithstanding anything in this Agreement to the
contrary, no default, delay or failure to perform on the part of
either party shall be considered a breach of this Agreement if
such default, delay or failure to perform is shown to be due
entirely to causes beyond the reasonable control of the party
charged with a default, including, but not limited to, causes
such as strikes or other labor disputes, riots, civil
disturbances, actions of governmental authorities, epidemics,
war, embargoes, severe weather, fire, earthquakes, acts of God or
the public enemy, nuclear disasters, or default of a common
carrier.

     (e) Wherever in this Agreement either party's consent is
required, such consent shall not unreasonably be withheld or
delayed.

     (f) This Agreement, together with the Exhibits hereto, the
Settlement Agreement and Mutual General Release, Amendment 14 to
the Software License Agreement, the Business Relations Agreement,
the Intergraph CSP Agreement and the Distribution Agreement,
collectively set forth the entire agreement and understanding
between and among the parties and, except as specifically
provided herein, supersede and merge all prior oral and written
agreements, discussions and understandings between the parties,
and neither of the parties shall be bound by any conditions,
inducements or representations other than as expressly provided
for herein or as fully set forth on or subsequent to the date
hereof in writing and signed by a proper and duly authorized
representative of the party to be bound hereby.  Unless otherwise
specified herein, this Agreement does not supersede or merge the
Software License Agreement dated April 17, 1987, as amended, the
Stock Purchase Agreement, the Stockholders' Agreement, or the
Software License Agreement For IGDS File Formats, or the Amended
License Agreement dated January 28, 1993.

     (g) The terms and conditions of this Agreement shall
prevail, notwithstanding any variance with any purchase order or
other written instrument submitted by Licensee, whether formally
rejected by BSI or not.  This Agreement may be amended or
modified only in a writing, signed by each party.

     (h) Notices under this Agreement shall be sufficient only if
mailed postage prepaid by certified or registered mail, return
receipt requested.  Notices by mail shall be deemed received
three business days after deposit.  Notices to BSI or Licensee as
appropriate, shall be sent to the address of such party specified
on the first page of this Agreement.

     (i) All disputes arising out of this Agreement shall be
settled by binding arbitration before a single arbitrator in
accordance with the Commercial Arbitration Rules of the American
Arbitration Association.  The arbitration will be conducted in
Wilmington, Delaware and the decision of the Arbitrator will be
final, and may be reduced to judgment in any court of competent
jurisdiction.  Each party shall bear its own costs and expenses
in connection with an arbitration proceeding.

     (j) This Agreement shall be interpreted and governed by the
substantive law of the State of Delaware.

     (k) BSI agrees to deposit a copy of the Source Code of the
Licensed Programs, including all software materials necessary for
a successful build of the Licensed Programs, with an independent
Escrow Agent under an Escrow Agreement in the form attached
hereto as Exhibit E.


     (l) Licensee may not distribute with Intergraph PointStation App
lications any BSI documentation, printed or on-line, other than
the Permitted Documentation provided pursuant to Exhibit G, and
then only with BSI's prior written consent.  The criteria for
such consent by BSI (which will not be unreasonably withheld)
will be its determination that the full documentation for the
Intergraph PointStation Application sufficiently emphasizes its
Significant Value Added, rather than the functions of the
Licensed Programs

          WHEREAS, Licensor and Licensee have entered into an OEM
Software License Agreement for MicroStation V5 Runtime Engine
(the "License Agreement") dated                   , pursuant to
which Licensor has licensed to Licensee certain computer
software, including updates  thereof from time to time developed
by Licensor (collectively, the "Product"); and

Escrow Agreement; and


          WHEREAS, Licensor and Licensee desire that upon the
occurrence of a "Default" as defined in Paragraph 6 hereof,
Licensee shall obtain the source code and all revisions thereof,
and accordingly, Licensor agrees to deliver said source code to
the Escrow Agent;


          NOW, THEREFORE, each intending to be legally bound
hereby, Licensor, Licensee and Escrow Agent agree as follows:


          1.   Source Code.  As used herein, "Source Code" means
a human readable form of the Product showing the computer
language instructions comprising the program, from which Object
Code can be produced, in which the program logic may be deduced
by a human being, and from which a printed listing can be made by

          2.   Engagement of Escrow Agent.  Licensor hereby
engages Escrow Agent and Escrow Agent hereby accepts such
engagement subject to the terms and conditions of this Agreement.
The Escrow Agent, acting as the agent of Licensor, shall accept
and hold the Source Code in a fireproof safe at its offices at
the address indicated above until the Escrow Agent receives
notice pursuant to the terms of this Agreement that the Escrow
Agent is to deliver the Source Code to Licensor or Licensee.


          3.   Deposit of Source Code.  Licensor shall deposit
the Source Code with the Escrow Agent on or before January 15,
1995.  Licensor shall deposit with the Escrow Agent Source Code
for modifications and enhancements, if any, to the Product within
ten (10) days of delivery of such modification or enhancements by
Licensor to Licensee.  Upon receipt of the Source Code and each
modification to the Source Code, the Escrow Agent shall send to
Licensee, with a copy to Licensor, a written confirmation that
the Source Code or additions thereto have been delivered to it.
The confirmation shall contain a list of the items which Licensor
has delivered to the Escrow Agent, and the date of such delivery.


          4.   Ownership.  The Source Code held by the Escrow
Agent shall remain the exclusive property of the Licensor, and
the Escrow Agent shall not use the Source Code or disclose the
same to any third party except as specifically provided for
herein.


          5.   Representations of Licensor to Licensee.  Licensor
represents and warrants to Licensee that (i) the Source Code
delivered to the Escrow Agent constitutes the source code for the
Product licensed to the Licensee pursuant to the License
Agreement; and (ii) the Source Code delivered to the Escrow Agent
is in a form suitable for reproduction by computer and photocopy
equipment, and consists of a source language statement of the
program or programs comprising the Product in sufficient detail
to allow a reasonably skilled third-party programmer or analyst
to modify, maintain or enhance the Product.


          6.   Default.  Licensor shall be deemed to be in
default of this Agreement upon the occurrence of any one of the
following events (each of which is called a "Default"):
               a.   if the Licensor fails to discharge any of its
maintenance obligations pursuant to the Product Support Program
for the Product in accordance with the written agreement between
the Licensor and Licensee, and such failure continues for thirty
(30) days after Licensee's notification to Licensor specifying in
detail in which respects the Product is not properly being
supported; or
               b.   if the Licensor become insolvent, makes a
general assignment for the benefit of creditors, files a
voluntary petition of bankruptcy, or suffers or permits the
appointment of a receiver for its business or assets; or
               c.   if the License Agreement is terminated by
reason of a material uncured breach by Licensee.




          7.   Release of Source Code.
               a.   Upon the occurrence of a "Default" as defined
above, Licensee shall give written notice (the "Notice of
Default") to Escrow Agent and Licensor of the occurrence of
Default.  The Notice of Default shall, at minimum, (i) be
labelled "Notice of Default", (ii) identify the License Agreement
and this Escrow Agreement, (iii) specify the nature of the
default, (iv) identify the Source Code with specificity, and (v)
instruct the Escrow Agent to transfer the Source Code to
Licensee.
               b.   Upon receipt of the Notice of Default, the
Escrow Agent shall send a copy thereof to the Licensor by
certified or registered mail, postage prepaid, return receipt
requested.  If the Licensor desires to dispute the Notice of
Default, the Licensor shall, within fourteen (14) days after the
receipt of the copy of the Notice of Default from the Escrow
Agent, deliver to the Escrow Agent a statement (the "Dispute
Statement") stating that no Default has occurred, whereupon the
provisions of Paragraph 11 below will become applicable.  If the
Escrow Agent receives the Dispute Statement within said fourteen
(14) days, the Escrow Agent shall send a copy thereof to Licensee
by certified or registered mail, return receipt requested, and
the Escrow Agent shall continue to hold the Source Code in
accordance with this Escrow Agreement.  If the Escrow Agent does
not receive a Dispute Statement within said fourteen (14) days,
the Escrow Agent is authorized and directed to deliver the Source
Code to the Licensee.


          8.   Use of Source Code; Confidentiality.
               a.   Upon the occurrence of a Default and receipt
by the Licensee of the Source Code, Licensee may use the Source
Code solely to modify, enhance and support the Product, and to
make a reasonable number of copies of the Source Code to assist
in the performance of such tasks;
               b.   Licensee acknowledges and agrees that the
Source Code constitutes confidential proprietary information of
the Licensor.  Licensee may disclose the Source Code only to
those employees required to have knowledge of such information to
perform their duties.  Licensee shall protect the Source Code
with the same degree of care as it protects its own confidential
information, and in no event less than a reasonable degree of
care.


          9.   Deposit with Escrow Agent After Default.  If a
Default occurs and is later cured, Licensee shall promptly return
the Source Code to the Escrow Agent.


          10.  Termination.  If the License Agreement terminates
pursuant to its expiration or a breach by Licensee,  Licensor
shall give notice of such termination to the Escrow Agent and
Licensee.  The Escrow Agent shall then transfer the Source Code
to Licensor and the Escrow Agreement will terminate.


          11.  Disputes.
               a.   In the event that Licensor files a Dispute
Statement with the Escrow Agent in the manner and within the time
period set forth in Paragraph 7(b) hereof, the Escrow Agent shall
not release the Source Code to Licensee except in accordance with
(i) a final decision of the arbitration panel as hereinafter
provided, or (ii) receipt of an agreement with authorized and
notarized signatures of both Licensor and Licensee, authorizing
the release of the Source Code to Licensee.
               b.   Disputes arising under this Agreement shall
be referred immediately to, and settled by, binding arbitration.
The arbitration panel shall consist of one person.  The
arbitration shall be conducted in Wilmington, Delaware in
accordance with the Commercial Arbitration Rules of the American
Arbitration Association.  The Escrow Agent shall give prompt
effect to any authenticated arbitration award.


          12.  Payment to Escrow Agent.  As compensation for the
services performed by the Escrow Agent hereunder, the Escrow
Agent shall receive a fee of                        ($
) per year, which fee may be reasonably increased by Escrow Agent

             LICENSED PROGRAM PRODUCT SPECIFICATION
             --------------------------------------

The Runtime Engine will be based on MicroStation Version 5, and
will not be upgraded or enhanced for future MicroStation versions
(such as Version 6).

1.0  Supported Functionality:

     A. Licensed Programs will contain only a subset of the
existing functionality of MicroStation V5 (except that there may
be additional code required to implement the mechanisms for
limiting the functionality of the Licensed Programs to less than
the functionality of MicroStation V5, and to limit the MicroCSL
and MDL applications that the Licensed Programs will execute to
the set of Accepted Applications). To the extent that the
functionality of MicroStation V5 on a particular Supported
Environment is less than its functionality on any other Supported
Environment, the functionality of the Licensed Programs on the
first such Supported Environment may contain only a subset of the
functionality of Licensed Programs on such other Supported
Environment.

     B.   Licensed Programs will contain the following
MicroStation V5 functionality:

          (i) MicroCSL Runtime Support

               (a) The Licensed Programs will support the
MicroCSL function set of V5.

               (b) The Licensed Programs will include the ability
to start MicroCSL Programs from among the set of MicroCSL
executables required for the operation of the Accepted
Applications only. Such MicroCSL executables must be started at
program startup time through the Licensed Programs' "-a" command
line switch facility.

               (c) The MicroCSL development environment for the
Licensed Programs will consist of the MicroCSL development
environment as delivered to accompany MicroStation V5. The
MicroCSL library itself may be different to accomodate the
changes required to restrict the MicroCSL programs that the
Licensed Programs will execute.

               (d) The MicroCSL runtime environment will include
the routines necessary to support the Intergraph-developed  "AS"
library. Intergraph is responsible for support of the "AS"
library.

          (ii)   MicroStation Development Language (MDL) Runtime
Support

               (a) The Licensed Programs will support the MDL
built-in function set of V5.

               (b) The Licensed Programs will include the ability
to start MDL programs from among the set MDL programs required
for the operation of the Accepted Applications only. Such MDL
programs must be started at program startup through the License
Programs "MS_INITAPP" and/or "MS_DGNAPP" facility.

               (c) The Licensed Programs will include the ability
to start the MDL utilities mentioned in Paragraph 1(b)(vi) of
this Exhibit F during the program session.

               (d) The MDL development environment for the
Licensed Programs will consist of the MDL development environment
as delivered to accompany MicroStation V5. Certain libraries may
be added or modified from those in the MicroStation V5
environment to accomodate the changes required to restrict the
MDL programs that the Licensed Programs will execute.

               (e) The Licensed Programs will include support for
MDL  functions including, but not limited to, ***

         
BUT only, as to each Supported Environment, to the extent that
such functions are available in MicroStation V5 for such
Supported Environment.
         

          (iii)   Dynamic Link Module (DLM) Runtime Support

               (a) The Licensed Programs will support DLM's and
such DLM's will have the functionality available to DLM's in
MicroStation V5. For a particular DLM to be supported, it must be
built with the compiler and linker used to build the Licensed
Programs on the Supported Environment.

               (b) The Licensed Programs will include the ability
to load DLM's from among the set of DLM's required for the
operation of the Accepted Applications.

          (iv)  To the extent that such support is included in
MicroStation V5, the Licensed Programs shall provide a tool kit
and hooks to extend element types and manipulations.

          (v) Database Support. To the extent that the databases
listed below are supported in MicroStation V5, they shall be
supported in the Licensed Programs.
            RIS
            Oracle
            Informix
            Xbase
            ODBC

          (vi) The Licensed Programs shall provide the following
utility programs with the functionality of MicroStation V5:
            EDG
            T23/T32
            DWG/DXF
            CGM
            Font Installer

          (vii) The Licensed Programs shall display 3D files
including any Open/GL functionality included in MicroStation V5
for a particular Supported Environment. In any event, the
Licensed Programs shall include support for the programming
interface known as "MOGLE" to the extent support is included in
MicroStation V5 for a particular Supported Environment.

          (viii) The Licensed Programs shall include ONLY the
rendering functionality included in MicroStation Draft, including
            wiremesh display
            raster hidden line display
            smooth shading display
             and
            global lighting display

          (ix) The Licensed Programs shall be constructed such
that an Accepted Application that runs on Licensed Programs can
be run on MicroStation V5 for the same Supported Environment.
Some source code modifications to the Accepted Application will
be required to accomodate the changes required to restrict the
MicroCSL, MDL, and DLM applications that the Licensed Programs
will execute, but those changes will not prevent the Accepted
Application so modified from running on MicroStation V5.
    
          (x) The Licensed Program shall provide a minimal 2D/3D
drafting Graphics User Interface that consists ONLY of:
    
               (a) A command window with functionality similar to
     the functionality of MicroStation V5's command window.
    
               (b) Command Palettes to access supported commands.
    
               (c) Dialog Boxes and Settings Boxes required to
set user-adjustable parameters used by the supported commands.
    
          (xi) The Licensed Programs shall use the Intergraph
     licensing API.
    
          (xii) The Licensed Programs shall support European
localization to the extent same is supported by MicroStation V5
for a particular Supported Environment.
    
          (xiii) The Licensed Programs shall support
internationalization for Asian languages to the extent supported
by MicroStation V5 for a particular Supported Environment.

     C.  Licensed Programs will include ONLY the subset of
MicroStation V5 commands that are included in Microstation Draft,
a copy of  the preliminary specification for which shall be
supplied by BSI within thirty (30) days of the date hereof and
attached to this Agreement as Exhibit H, and shall at a minimum
include the following:
    
     ***

     D.   Commands and features that are included in MicroStation
Draft but are not included in MicroStation V5 will NOT be
supported in the Licensed Programs.  Additionally, the following
commands and features will NOT be supported in the Licensed
Programs regardless of whether or not they are included in
MicroStation Draft:

            Tutorials
            Cursor Alignments
            Constraint placement
            Advanced rendering options (except as noted above)

                            EXHIBIT G
                            ---------

            DEVELOPMENT PLAN, ACCEPTANCE AND REMEDY

1.  Intergraph shall provide to BSI no later than May 16, 1994 a
list and price-book descriptions (including the U.S. list prices
as of March 30, 1994) of all products existing at March 30, 1994
which it believes meet the criteria set forth in sub-paragraphs
(i) through (iv) of the definition of "Accepted Application" in
Section I(l) ("the Criteria"), and which it desires to integrate
with the Licensed Programs to create Intergraph PointStation
Applications.  No   Intergraph products existing at March 30,
1994 other than those listed therein will be considered to meet
the Criteria, and BSI shall have no obligations hereunder with
respect to such other Intergraph products existing at March 30,
1994.  Subsequent Intergraph applications, upon Intergraph's
written request, will ultimately be considered as candidates for
Accepted Applications with respect to the criteria in
subparagraphs (i), (ii), (iii), and (v) in Section I(l), but will
not be a condition for determination of initial Deficiencies
pursuant to Paragraph 4 below.

2.  Intergraph shall, no later than July 1, 1994, supply to BSI
the MicroCSL executable names, MDL application names, and DLM
names required for operation of each Accepted Application.

3.  BSI shall use best efforts to implement the Runtime Engine as
set forth in Exhibit F,  test it and deliver it to Licensee on or
before August 30, 1994.  BSI will extract a subset of the
MicroStation Version 5 Reference Manual that addresses the end
user command subset available in the Licensed Programs and
provide it in machine-readable form as Permitted Documentation
for inclusion in Intergraph PointStation documentation. BSI will
provide this material in "as is" condition.

4.  Licensee shall, no later than November 15, 1994, specifically
identify in writing to BSI any Deficiencies in the Runtime
Engine. As used in this paragraph, a "Deficiency" means an
instance in which an Accepted Application successfully executes
on MicroStation V5, but fails to execute substantially the same
functions on the Runtime Engine, where such failure is due to
causes other than differences between MicroStation V5 and the
Runtime Engine defined in Exhibit F sections B(vii), B(viii),
B(x), C and D.

5.  In the event that BSI fails to correct on or before
December 31, 1994, a Deficiency reported to it by Licensee before
November 15, 1994 (unless the Runtime Engine was delivered to
Licensee after August 30, 1994, in which case Licensee shall
notify BSI of any Deficiency no later than ninety (90) days after
the Runtime Engine is delivered to Licensee, and BSI shall have
until thirty (30) days thereafter to correct it), Licensee shall
be entitled to temporarily loan copies of MicroStation V5, to End
Users at the royalty rate provided herein for such Accepted
Applications only.  BSI shall furnish such loan copies to
Licensee.  At such time as BSI has corrected such Deficiency,
Licensee shall furnish the applicable Intergraph PointStation
Application to the End Users, retrieve from the End Users the
loaned copies of MicroStation V5 and return such copies to BSI.

                          ---------
                              
              "MicroStation Draft" Command Set
                             and
              MicroStation Engine Specification
                             



This document provide specification for the MicroStation
Runtime Engine (MRTE) to be developed by Bentley Systems,
Inc. for use by Intergraph Corporation in accordance with
the provisions of the OEM SOFTWARE LICENSE AGREEMENT FOR
MICROSTATION V5 RUNTIME ENGINE dated May 2, 1994.  This
document is supplied as Appendix H of the abovementioned
agreement, but it includes not only the "MicroStation Draft"
(Note 1) Command set but additional specifications which
will be helpful to Intergraph to begin planning for the
MRTE.

Exhibit H.1 lists the MDL applications that are included in
the MRTE, although in some cases the functionality of these
MDL applications is limited compared to their functionality
in MicroStation Version 5 as documented herein.  Exhibit H.2
lists the standalone utility programs included with the
MRTE.  The database servers from MicroStation Version 5 are
included unmodified in the MRTE, and are not listed since
they vary from one platform to another.

The MicroStation Draft command set is documented in a
spreadsheet in Exhibit H.3.  The first column contains every
command that is contained in the core of MicroStation
Version 5.0 and additionally those in the MDL applications
that are included with MicroStation Draft.  MicroStation
Draft includes some additional commands that are not listed
because they were not supported in MicroStation Version 5,
and are thus explicitly excluded from the MRTE in the OEM
Agreement.  The second column lists whether the command is
supported in Draft.  Blank entries are interpreted as "YES".
The third column lists whether the command is supported is
MRTE.  Again, blank entries are interpreted as YES.  If the
command IS NOT supported in MicroStation Draft but IS
supported in MRTE, the column has YES explicitly for
contrast.  The fourth column indicates whether a user
interface is provided for the command in the MRTE.  The
fifth column consists of some comments for commands for
which clarification is necessary.




- ------------------------------------
Note 1:  The final product may be called something other
than MicroStation Draft.

                  DISTRIBUTION AGREEMENT
                  ----------------------


          THIS AGREEMENT is entered into this 2nd day of
May, 1994, by and between INTERGRAPH CORPORATION
("Intergraph"), a Delaware corporation having its principal
office and place of business at One Madison Industrial Park,
Huntsville, Alabama 35894, and BENTLEY SYSTEMS, INCORPORATED
("BSI"), a Delaware corporation having its principal office
and place of business at 690 Pennsylvania Drive, Exton,
Pennsylvania 19341.

                      W I T N E S S E T H:

          WHEREAS, the parties hereto are parties to a
Settlement Agreement and Mutual General Release of even date
herewith, which is one of several agreements that
collectively comprise the definitive agreement among the
parties in settlement of certain litigation and arbitration
proceedings pending between and among them;

          WHEREAS, BSI has developed computer programs
entitled MicroStation, MicroStation Review, MicroStation
Modeler, MicroStation Field and MicroStation Draft;

          WHEREAS, as part of the definitive agreement, the
parties hereto have agreed to enter into this Agreement
pursuant to which BSI shall give Intergraph certain rights
to distribute certain BSI software.

          NOW, THEREFORE, intending to be legally bound
hereby, the parties hereto agree as follows:

                           ARTICLE I
                          DEFINITIONS
                          -----------

          The following words, terms and phrases shall in
this Agreement have the following meanings:

          1.01  "Additional Module" means an additional
Product sold for installation on the same workstation with
another Product.

          1.02  "Agent" means a third party that sells the
Products on behalf of Intergraph to End Users for
compensation and without taking title to the Products.  An
Agent is not an employee of Intergraph.

          1.03 "Direct Account" means an account existing as
of January 1, 1995, on which a member of the Intergraph
direct sales force regularly calls in person and where title
to all Products purchased by such account passes directly
from Intergraph to such account without direct or indirect
compensation to an Agent.

          1.04  "Distributor" or "Reseller" means a person
that purchases Products from Intergraph and resells such
Products to a Reseller or an End User.

          1.05  "End User" means a person or entity that
purchases copies of one or more of the Products from
Intergraph or a Distributor or Reseller of Intergraph, and
uses such Products solely to fulfill its own internal needs
(and not for redistribution, remarketing, timesharing or
service bureau use) in accordance with the terms of an End
User License.

          1.06  "End User License" means the written shrink-
wrapped license agreement contained in each Product Kit
pursuant to which BSI, as Licensor, grants to an End User
the limited right to use a Product.

          1.07  "Intergraph" means Intergraph Corporation, a
Delaware corporation, and all subsidiaries and affiliates,
which means entities in which Intergraph owns more than
fifty percent (50%) of the outstanding common stock.

          1.08  "Intergraph Substantial Value Added
Application" refers to a determination made, as to a
computer software application program, with respect to a
particular Product (unless otherwise mutually agreed in
writing) as follows:

               (a) it must be computer software developed by
Intergraph (which may contain third-party content
compromising less than 50% of the object code), or to which
Intergraph has the exclusive distribution license in the
United States, and which prerequisites (that is, technically
requires for its operation) the Product, and which is
actively marketed and sold as a product to End Users and
Resellers for operation with such Product, and

                    (i) has a bona fide Intergraph U.S. list
price of at least twenty-five percent (25%) of the U.S. list
price of the Product which it prerequisites; or

                    (ii) if it is an application which is
actively marketed by Intergraph as of March 30, 1994, it
shall be deemed to be an Intergraph Substantial Value Added
Application with respect to MicroStation if its U.S. list
price on that date exceeds One Thousand Dollars ($1000.00);
and it shall be deemed an Intergraph Substantial Value Added
Application with respect to MicroStation Review if it
prerequisites MicroStation Review and its U.S. list price
exceeds Five Hundred Dollars ($500.00).  Notwithstanding the
foregoing sentence, the *** applications
are considered to be Intergraph Substantial Value Added
Applications with respect to MicroStation, and in no event
will any member of the ***
family of products be considered Intergraph Substantial
Value Added Applications.

          1.09  "Intergraph-Manufactured Computer System"
means a computer system manufactured by or for Intergraph
for distribution under the Intergraph brand name.

          1.10  "Intergraph Project Services" means bona

               (a)  BSI shall have and retain sole ownership
of the Trademarks, including the goodwill pertaining
thereto.  Intergraph shall market, distribute and support
the Products only under the applicable Trademarks, and not
under any other trademark or logo.  Intergraph shall not use
the Trademarks or any word, symbol or design confusingly
similar thereto, as part of its corporate name, or as part
of the name of any product of Intergraph.  Intergraph shall
not remove or alter any copyright notices, trademarks or
logos from the Product Kits.

               (b)  To protect and preserve the goodwill and
image of BSI and the Products, Intergraph shall (i) conduct
business in a manner that reflects favorably at all times on
the Products and the reputation of BSI; (ii) avoid
deceptive, misleading or unethical practices that are or
might be detrimental to BSI, the Products or the public,
including any disparagement of BSI or the Products; (iii)
make no false or misleading representations with respect to
BSI or the Products; (iv) refrain from publishing or
employing any misleading or deceptive advertising material
with respect to the Products; and (v) refrain from making
any representations, warranties or guarantees to its
Distributors, Resellers or End Users with respect to the
specifications, features or capabilities of Products that
are inconsistent with the End User Licenses or the
documentation contained in the Product Kits.

          9.02 No Copying, Etc.  Except as specified herein,
Intergraph shall not, without the prior written consent of
BSI, copy, reverse engineer, disassemble, decompile,
translate or modify the Products, or grant any other person
or entity the right to do so.

          9.03 Notification of Infringement, Etc.
Intergraph shall promptly notify BSI of (a) any claims,
allegations or notification that the marketing, licensing or
use of the Products may or will infringe any patent,
copyright, trademark or other intellectual property right of
any other person or entity; (b) any determination or
discovery that any person or entity is or may be infringing
any copyright, patent, trademark or other intellectual
property right owned by BSI; and (c) any failure of an End
User to comply with the Registration requirements for the
Products.

          9.04 Indemnification.  BSI shall defend and hold
Intergraph harmless from all claims, suits, damages and
expenses (including attorney's fees) arising from a claim
that a Product supplied hereunder infringes a United States
patent, copyright or other intellectual property right,
provided that BSI receives prompt written notice of any such
claim from Intergraph, and BSI is afforded the opportunity
to exercise sole control of the defense and all negotiations
pertaining to such claim.  BSI shall also have the right, at
its expense, either to procure the right for Intergraph to
continue to distribute such Product, or to replace or modify
it so that it becomes non-infringing.  If neither of the
foregoing alternatives is available on terms that BSI, in
its sole discretion, deems desirable, Intergraph shall
return Product Kits containing such Product upon written
request from BSI, in which event BSI shall grant Intergraph
a credit equal to the price paid by Intergraph for such
returned Product Kits, provided that they are undamaged.

          9.05  Escrow.   Within sixty (60) days of the date
of this Agreement, BSI agrees to deposit a copy of the
source code and all software material for a successful build
of the Product in escrow with an escrow agent and under an
escrow agreement acceptable to BSI and Intergraph, in the
form of Exhibit B hereto.  BSI will supplement the source
code in escrow to maintain it at a level that is consistent
with the current release available for sale to End Users.
Upon any termination of this Agreement by Intergraph
pursuant to Paragraphs 10.02 or 10.03, or pursuant to
Paragraph 10.04 hereof by reason of termination by
Intergraph of the Software License Agreement or the Business
Relations Agreement, Intergraph shall have the right to
withdraw the materials from escrow and to make them
available to no more than three (3) employees of Intergraph,
who will agree to maintain the materials in confidence for
the benefit of BSI, and who will use the material solely for
the purpose of maintaining and supporting existing licensed
End Users of Product.  The obligations under this section
will survive any termination of this Agreement, and will
remain in effect until no End User requires support and
maintenance of the Product, at which time the materials will
be returned to BSI or its successor in interest.

                ARTICLE X.  TERM; TERMINATION
                -----------------------------

          10.01  Term.  This Agreement, which is the
successor agreement to the Software License Agreement
between the parties hereto, shall become effective on
January 1, 1995, and shall continue indefinitely, unless
sooner terminated as provided herein.

          10.02  Termination for Material Breach.

          (a)  This Agreement may be terminated for a
material breach of this Agreement, but only pursuant to the
procedures set forth in this Paragraph 10.02. If this
Agreement is terminated due to termination of the Business
Relations Agreement, or the Software License Agreement as
amended, termination of this Agreement shall be done only in
accordance with this Paragraph 10.02. If either party
believes that a material breach of this Agreement has
occurred, that party (the "aggrieved party") must first give
the other party written notice of termination specifically
identifying the breach or breaches alleged to have occurred.
The party receiving written notice shall then have thirty
(30) days in which to cure such breach or breaches.  If
within the thirty (30) days the breach or breaches are not
cured to the satisfaction of the aggrieved party, then the
aggrieved party may file a Demand For Arbitration seeking a
determination of whether a material breach has occurred.
Such Demand for Arbitration shall be determined in
accordance with the procedures set forth in Paragraph 11.09
hereof.  Except for claimed breaches involving payment
obligations where the paying party has failed to make timely
payment of at least fifty percent (50%) of the disputed
amount to the other party, neither party may withhold its
performance under this Agreement unless and until there has
been a final determination pursuant to Paragraph 11.09 that
a material breach has occurred.  The parties agree to take
all reasonable steps necessary to expedite a final
determination in accordance with Paragraph 11.09.

          (b)  The parties hereto specifically agree and
acknowledge that subparagraph (a) sets forth an essential
and unique provision of this Agreement and that the failure
of either party strictly to adhere to the terms of
subparagraph (a) above, including unilaterally withholding
its performance under this Agreement, will cause irreparable
harm to the other party.  The parties further specifically
agree and acknowledge that either party shall be entitled to
injunctive relief to enforce strictly the terms of
subparagraph (a).

          (c)  If BSI withholds performance under this
Agreement, then Intergraph shall have available to it the
following rights:

               (i) If BSI has withheld performance by
failing or refusing to supply Product to Intergraph,
Intergraph shall then have a license to copy and distribute
Product in accordance with this Agreement;

               (ii)  If BSI has withheld performance by
failing to provide to Intergraph any error correction change
to the Product, which change has been provided by BSI to any
third party, then Intergraph shall have the right to
withdraw and use source code under the terms of Paragraph
9.05.

     Intergraph will continue to have the rights set forth
in this Paragraph 10.02(c) until either (1) BSI resumes
performance in accordance with the terms of this Agreement
or (2) there is a final determination pursuant to Paragraphs
10.02(a) that Intergraph has committed a material breach of
this Agreement, whichever first occurs.

          10.03  Bankruptcy.  If either party shall file or
have filed against it any bankruptcy or similar proceeding,
or enter into any formal arrangement with its creditors, or
demonstrate a financial condition of such nature that the
other party may reasonably believe that such party may not
be capable of performing all of its obligations under this
Agreement, or cease doing business in the ordinary course,
then the other party shall have the right to terminate this
Agreement upon thirty (30) days written notice.

          10.04     Termination of Collateral Agreements.
Upon the sooner of a termination of (i) the Software License
Agreement dated April 17, 1987 between BSI and Intergraph
prior to December 31, 1994 or (ii) the Business Relations
Agreement dated of even date herewith between BSI and
Intergraph, then this Agreement may be terminated, but only
in accordance with the provisions of Paragraph 10.02 of this
Agreement.

          10.05     Consequences of Termination.  Upon
termination of this Agreement pursuant to Paragraph 10.02,
10.03 or 10.04 hereof, Intergraph may continue to dispose of
its existing inventories of Product Kits, but it shall
otherwise discontinue all further promotion and marketing of
the Products.  Without limiting the generality of the
foregoing, Intergraph shall cease all display, advertising
and use of all Trademarks of BSI and will not thereafter
use, advertise or display any such Trademarks.  Upon
termination of this Agreement, the due date of all
outstanding invoices for the Products Kits shall
automatically be accelerated and all such invoices shall
become due and payable.  All orders or portions thereof
remaining unshipped as of the effective date of termination
may be canceled by BSI.  Upon termination of this Agreement,
BSI shall have the option, which it may exercise at any time
by written notice to Intergraph, to repurchase some or all
of the remaining uncommitted inventory of Product Kits held
by Intergraph.  BSI shall pay Intergraph for all Product
Kits so repurchased (if received in a new and resalable
condition) an amount equal to the price paid by Intergraph
to BSI.

          10.06     Survival.  Paragraphs 2.02, 3.06, 3.09,
4.03, 5.06, and 5.07  and Articles VI, VIII, IX, X, and XI
shall survive the termination of this Agreement.

                  SOURCE CODE ESCROW AGREEMENT


          THIS IS AN AGREEMENT, dated                   ,
1994, by and among Intergraph Corporation, a Delaware
corporation having a mailing address of One Madison
Industrial Park, Huntsville, Alabama 35894, Bentley Systems,
Incorporated("BSI"), a Delaware corporation having a mailing
address of 690 Pennsylvania Drive, Exton, Pennsylvania 19341
and                    ("Escrow Agent"), having a mailing
address of                             .


                      W I T N E S S E T H:


          WHEREAS, BSI and Intergraph have entered into a
Distribution Agreement for MicroStation (the "Distribution
Agreement") dated May 2, 1994, pursuant to which BSI shall
distribute to Intergraph certain computer software products,
including updates thereof (the "Products"); and


          WHEREAS, BSI desires not to disclose the source
code for the Products to Intergraph except as provided in an
applicable Escrow Agreement; and


          WHEREAS, BSI and Intergraph desire that upon the
occurrence of a "Default" as defined in Paragraph 6 hereof,
Intergraph shall obtain the source code and all updates
thereof, and accordingly, BSI agrees to deliver said source
code to the Escrow Agent;


          NOW, THEREFORE, each intending to be legally bound
hereby, BSI, Intergraph and Escrow Agent agree as follows:


          1.   Source Code.  As used herein, "Source Code"
means a human readable form of the Products showing the
computer language instructions comprising the programs, from
which Object Code can be produced, in which the program
logic may be deduced by a human being, and from which a
printed listing can be made by processing it with a
computer.


          2.   Engagement of Escrow Agent.  BSI hereby
engages Escrow Agent and Escrow Agent hereby accepts such
engagement subject to the terms and conditions of this
Agreement.  The Escrow Agent, acting as the agent of BSI,
shall accept and hold the Source Code in a fireproof safe at
its offices at the address indicated above until the Escrow
Agent receives notice pursuant to the terms of this
Agreement that the Escrow Agent is to deliver the Source
Code to BSI or Intergraph.


          3.   Deposit of Source Code.  BSI shall deposit
the Source Code with the Escrow Agent on or before January
15, 1995.  BSI shall deposit with the Escrow Agent Source
Code for updates, if any, to the Products within ten (10)
days of delivery of each update by BSI to Intergraph.  Upon
receipt of the Source Code and each update to the Source
Code, the Escrow Agent shall send to Intergraph, with a copy
to BSI, a written confirmation that the Source Code or
additions thereto have been delivered to it.  The
confirmation shall contain a list of the items which BSI has
delivered to the Escrow Agent, and the date of such
delivery.

          4.   Ownership.  The Source Code held by the
Escrow Agent shall remain the exclusive property of BSI, and
the Escrow Agent shall not use the Source Code or disclose
the same to any third party except as specifically provided
for herein.

          5.   Representations of BSI to Intergraph.  BSI
represents and warrants to Intergraph that (i) the Source
Code delivered to the Escrow Agent constitutes the source
code for the Products distributed to Intergraph pursuant to
the Distribution Agreement; and (ii) the Source Code
delivered to the Escrow Agent is in a form suitable for
reproduction by computer and photocopy equipment, and
consists of a source language statement of the program or
programs comprising the Product in sufficient detail to
allow a reasonably skilled third-party programmer or analyst
to modify, maintain or enhance the Products.
          6.   Default.  BSI shall be deemed to be in
default of this Agreement upon the occurrence of any one of
the following events (each of which is called a "Default"):

               a.   if the Distribution Agreement is
terminated by Intergraph pursuant to Paragraph 10.03 of the
Distribution Agreement; or

               b.   if the Distribution Agreement is
terminated by Intergraph by reason of a material uncured
breach by BSI pursuant to Paragraph 10.02 of the
Distribution Agreement; or

               c.   if the Distribution Agreement is
terminated by Intergraph in accordance with the provisions
of Paragraph 10.04 of the Distribution Agreement by reason
of a material uncured breach by BSI of the Software License
Agreement or the Business Relations Agreement.


          7.   Release of Source Code.

               a.   Upon the occurrence of a "Default" as
defined above, Intergraph shall give written notice (the
"Notice of Default") to Escrow Agent and BSI of the
occurrence of Default.  The Notice of Default shall, at
minimum, (i) be labelled "Notice of Default", (ii) identify
the Distribution Agreement and this Escrow Agreement, (iii)
specify the nature of the default, (iv) identify the Source
Code with specificity, and (v) instruct the Escrow Agent to
transfer the Source Code to Intergraph.

               b.   Upon receipt of the Notice of Default,
the Escrow Agent shall send a copy thereof to BSI by
certified or registered mail, postage prepaid, return
receipt requested.  If BSI desires to dispute the Notice of
Default, BSI shall, within fourteen (14) days after the
receipt of the copy of the Notice of Default from the Escrow
Agent, deliver to the Escrow Agent a statement (the "Dispute
Statement") stating that no Default has occurred, whereupon
the provisions of Paragraph 11 below will become applicable.
If the Escrow Agent receives the Dispute Statement within
said fourteen (14) days, the Escrow Agent shall send a copy
thereof to Intergraph by certified or registered mail,
return receipt requested, and the Escrow Agent shall
continue to hold the Source Code in accordance with this
Escrow Agreement.  If the Escrow Agent does not receive a
Dispute Statement within said fourteen (14) days, the Escrow
Agent is authorized and directed to deliver the Source Code
to Intergraph.


          8.   Use of Source Code; Confidentiality.

               a.   Upon the occurrence of a Default and
receipt by  Intergraph of the Source Code, Intergraph may
use the Source Code solely to modify, enhance and support
the Products, and to make a reasonable number of copies of
the Source Code to assist in the performance of such tasks.

               b.   Intergraph acknowledges and agrees that
the Source Code constitutes confidential proprietary
information of BSI.  Intergraph may disclose the Source Code
only to those employees required to have knowledge of such
information to perform their duties.  Intergraph shall
protect the Source Code with the same degree of care as it
protects its own confidential information, and in no event
less than a reasonable degree of care.


          9.   Deposit with Escrow Agent After Default.  If
a Default occurs and is later cured, Intergraph shall
promptly return the Source Code to the Escrow Agent.

          10.  Termination.  If the Distribution Agreement
terminates pursuant to its expiration or a breach by
Intergraph, BSI shall give notice of such termination to the
Escrow Agent and Intergraph.  The Escrow Agent shall then
transfer the Source Code to BSI and the Escrow Agreement
will terminate.


          11.  Disputes.
               a.   In the event that BSI files a Dispute
Statement with the Escrow Agent in the manner and within the
time period set forth in Paragraph 7(b) hereof, the Escrow
Agent shall not release the Source Code to Intergraph except
in accordance with (i) a final decision of the arbitrator
as hereinafter provided, or (ii) receipt of an agreement
with authorized and notarized signatures of both BSI and
Intergraph, authorizing the release of the Source Code to
Intergraph.

               b.   Disputes arising under this Agreement
shall be referred immediately to, and settled by, binding
arbitration.  The arbitration panel shall consist of one
person.  The arbitration shall be conducted in Wilmington,
Delaware in accordance with the Commercial Arbitration Rules
of the American Arbitration Association.  The Escrow Agent
shall give prompt effect to any authenticated arbitration
award.


          12.  Payment to Escrow Agent.  As compensation for
the services performed by the Escrow Agent hereunder, the
Escrow Agent shall receive a fee of
($              ) per year, which fee may be reasonably
increased by Escrow Agent from time to time.  Intergraph
shall bear all fees charged by Escrow Agent.


          13.  Termination.  This Escrow Agreement shall
terminate upon the delivery of the Source Code by Escrow
Agent to BSI or Intergraph in accordance with the terms of
this Agreement; provided, however, if BSI cures a Default
after delivery of the Source Code to Intergraph, this
Agreement shall be reinstated.


          14.  Obligations and Liabilities of Escrow Agent.

               a.   The Escrow Agent shall have no
obligation or responsibility whatsoever to determine (i) the
existence, relevance, completeness, currency, accuracy, or
any other aspects of the Source Code or (ii) whether what is
deposited by BSI is the Source Code as defined herein.

               b.   The Escrow Agent shall exercise a high
degree of care for the Source Code.  The level of care
exercised shall be at least as high as the Escrow Agent
would use to protect its own valuable documents.

               c.   The Escrow Agent shall not be
responsible for the genuineness of any affidavit or
signature and may rely conclusively upon and shall be
protected when acting upon any notice, affidavit, or other
document believed by it in good faith to be genuine and
properly made.

               d.   The Escrow Agent shall not be
responsible or liable for any act or omission on its part in
the performance of its duties as Escrow Agent under this
Agreement, except as such act or omission constitutes gross
negligence, willful misconduct or fraud, or violates the
Escrow Agent's obligation under subparagraph (b) above.

               e.   The Escrow Agent shall not be
responsible in any manner whatsoever for any failure or
inability of BSI or Intergraph to deliver the Source Code to
Escrow Agent or otherwise honor any of the provisions of
this Agreement.

               f.   Intergraph and BSI, jointly and
severally, shall reimburse and indemnify the Escrow Agent
for, and hold it harmless against any loss, liability or
expense, including counsel fees, incurred without bad faith,
willful misconduct or gross negligence on the part of the
Escrow Agent, arising out of or in connection with its
acceptance of, or performance of, its duties and obligations
under this Agreement, except the Escrow Agent's obligations
under subparagraph (b) above.

               g.   Escrow Agent shall not divulge,
disclose, use or otherwise make available to third parties
the Source Code except as provided in this Agreement.

          15.  Modifications and Amendments.  This Agreement
shall not be amended or modified except by a written
agreement signed by all of the parties hereto.

          16.  Entire Agreement.  This Agreement contains
the entire agreement between the parties with respect to the
escrow of the Source Code, and there are no other terms or
conditions, express or implied, written or oral.  This

          CERTIFIED MAIL - RETURN RECEIPT REQUESTED


March 7, 1994

James W. Meadlock
President
Intergraph Corporation
One Madison Industrial Park
Huntsville, AL   35807

RE:  Notice of Breach of Software License Agreement Between
Bentley Systems, Inc. and Intergraph Corporation dated April
17, 1987, As Amended.

Dear Mr. Meadlock:

Pursuant to Paragraph 13.3 of the Software License Agreement
between Bentley Systems, Inc. and Intergraph Corporation
dated April 17, 1987, As Amended, Bentley Systems, Inc.
(Licensor) hereby serves notice of Intergraph Corporation's
material breaches of the Agreement, as follows:

(i)  Good Faith Efforts.

Para. 9.6 of the License Agreement provides:

"Marketing.  Licensee agrees to use good faith efforts in
promoting and sub-licensing the Licensed Programs in
substantially all worldwide markets in which Intergraph
Hardware and Intergraph Software are sold."

Intergraph has breached this covenant by failing to use good
faith efforts to promote and sublicense some or all of the
Licensed Programs.  For example, Intergraph's marketing
efforts for MicroStation Review have been deliberately
limited to the point of declining to bid on substantial
procurements aggregating to millions of dollars of potential
MicroStation Review revenues.

(ii)  Sales of upgrades in Support Plans.

Paras. 7.1 & 7.2 (as amended Amend. No. 8, 09/28/92)
provides for a Comprehensive Support Plan (CSP) to be
offered by BSI and a Basic Support Plan (BSP) to be offered
by Intergraph for platforms other than Intergraph Clipper
workstations and SPARCs sold by Intergraph.  Para. 7.1
states that CSP will include upgrades for the Licensed
Programs.  Para. 7.2 states that Intergraph's BSP "...shall
not include Licensed Programs upgrades."

Intergraph has breached these provisions by promoting
offerings such as the "MicroStation Support Program" (U.S.)
and "Solutions Support Program" (Australia), which
essentially bundle Licensed Program upgrades with these
support programs.

(iii)  Pricing of Unauthorized Upgrades in (ii).

Para. 5.2 provides:

"List Price.  The List Price and associated discounts for
the Licensed Programs shall be mutually agreed upon from
time to time between Licensor and Licensee."

Amend. No. 13, para. 5.1(b) provides specific upgrade prices
for the Licensed Programs.

Intergraph has further breached the License Agreement in its
pricing of the unauthorized upgrades described in (ii) above
at levels which are different from the agreed list prices
and/or accepted discount levels.


(iv)  Copyright Marking of V5 Kits.

Para. 3 of the License Agreement provides:

"Licensee shall have the right to market the Licensed
Programs under any tradename it desires so long as Licensor
is identified as the proprietary owner of the Licensed
Programs.  Licensee shall place Licensor's copyright notice
in human readable form on the package of each copy of the
Licensed Programs sold by Licensee."

Intergraph has breached this provision by failing to put
BSI's copyright notice on the MicroStation V5 kit package,
on the media, and in advertisements and other promotional
materials.

(v)  MicroStation "Reissues" for Platform Swaps.

Intergraph has breached the License Agreement by instituting
a "Software Reissue Policy" which offers End Users new
copies of the Licensed programs on different platforms than
that specified in such Users' sub-licenses, upon payment to
Intergraph of either 10% (with Intergraph hardware) or 20%
of the list price.  A change in licensing terms which could
conceivably have permitted this was sought by Intergraph as
section 5.3 of its originally proposed Amendment 12, but it
was stricken before execution at BSI's insistence.

(vi)  Imposition of Unlawful Conditions--Kits for CSP
Distribution.

Amend. No. 13, para. 5.1(d) provides:

"Licensee agrees to sell DOS and MAC O/S versions of the
packaged Licensed Programs to Licensor at its current cost
of packaging.  The copies provided under this provision are
to be used for Licensor's ISD program, for Licensor's
Comprehensive Support Program..."

Intergraph has breached this provision of the License
Agreement by attempting to impose conditions on this
contractual duty.  Intergraph has demanded that BSI furnish
the identification of its CSP subscribers to Intergraph as a
condition of procuring the kits that BSI has a contractual
right to obtain unconditionally.  In any event, such kits
have not been timely supplied.

(vii)  Discount Changes--Without BSI Concurrence.

See para. 5.2 as quoted above.

Intergraph has beached this provision of the License
Agreement by changing all reseller discounts for  the
Licensed Programs, without BSI approval.

(viii)  Explicitly Prohibited use of "Plotlib".

Amendment 12 on July 30, 1993 in paragraph 2 provides for
Intergraph's use (without compensation) of a BSI software
library "for use with Licensee's EMS 2.x and network
plotting applications...this library is not to be used for
file viewing on graphic displays."

An Intergraph document headed "DM/View, DM/Redline Facts
Sheet 9/15/93" contains the statement that "XDMANDS display
code utilizes libustn.a supplied by BSI to the Plotting
Group for CLIX platforms."  This is expressly prohibited by
the License Agreement.



Sincerely,

\s\ Keith A. Bentley

Keith A. Bentley
President
