                                BASIC TRANSACTION

      2.1 Merger; Surviving Corporation. In accordance with the provisions of
this Agreement, the General Corporation Law of the State of Delaware ("DGCL")
and the Business Corporation Act of the State of Florida ("FBCA"), at the
Effective Time the Company shall be merged with and into Merger Sub, and Merger
Sub shall be the surviving corporation in the Merger (hereinafter sometimes
called the "SURVIVING CORPORATION") and shall continue its corporate existence
under the laws of the State of Delaware. At the Effective Time, the separate
existence of the Company shall cease. All properties, franchises and rights
belonging to the


                                     - 6 -
<PAGE>

Company and Merger Sub, by virtue of the Merger and without further act or deed,
shall be deemed to be vested in the Surviving Corporation, which shall
thenceforth be responsible for all the liabilities and obligations of each of
Merger Sub and the Company.

      2.2 Certificate of Incorporation. At the Effective Time, Article 1 of the
Certificate of Incorporation of Merger Sub, as in effect immediately prior to
the Effective Time, shall be amended to read in its entirety as follows:

                  "1. Name: The name of the corporation shall be Geopak
Corporation."

Except for such amendment, the Certificate of Incorporation of Merger Sub as in
effect immediately prior to the Effective Time shall thereafter continue in full
force and effect as the Certificate of Incorporation of the Surviving
Corporation until altered or amended as provided therein or by applicable law.

      2.3 By-laws. Merger Sub's By-laws as in effect immediately prior to the
Effective Time shall be the By-laws of the Surviving Corporation until altered,
amended or repealed as provided therein or by applicable law.

      2.4 Directors and Officers. The directors of Merger Sub immediately prior
to the Effective Time shall serve as directors of the Surviving Corporation
following the Effective Time in accordance with the Certificate of Incorporation
and By-laws of the Surviving Corporation and the DGCL. The officers of the
Company immediately prior to the Effective Time shall serve in such capacities
at the pleasure of the Board of Directors of the Surviving Corporation following
the Effective Time in accordance with the Certificate of Incorporation and
By-Laws of the Surviving Corporation and the DGCL.

      2.5 Effective Time. The Merger shall become effective at the time and date
that the last of the following two events has occurred: (i) the acceptance for
filing of a certificate of merger (the "DGCL CERTIFICATE OF MERGER"), in the
form attached hereto as Exhibit 1, by the Secretary of State of the State of
Delaware in accordance with the provisions of Section 252 of the DGCL; and (ii)
the acceptance for filing of articles of merger (the "FBCA ARTICLES OF MERGER"),
in the form attached hereto as Exhibit 2, by the Secretary of State of the State
of Florida, in accordance with Section 607.1109 of the FBCA. The DGCL
Certificate of Merger and the FBCA Articles of Merger shall be executed by
Merger Sub and/or the Company, as applicable, and delivered to the Secretary of
State of the State of Delaware and the Secretary of State of the State of
Florida, respectively, for filing, as stated above, on the Closing Date. The
date and time when the Merger shall become effective are referred to herein as
the "Effective Time."

      2.6 Conversion of Securities.

                  (a) At the Effective Time, all of the issued and outstanding
shares of Company Common Stock other than Company Common Stock owned by Bentley
shall be converted into the right to receive following (the "MERGER
CONSIDERATION"):


                                     - 7 -
<PAGE>

                        (i) cash in an amount equal to $8,000,000;

                        (ii) 35,000 shares of Bentley's Class C Senior Common
Stock to be issued in accordance with the Joinder to the Securities Purchase
Agreement;

                        (iii) 480,000 shares of Bentley's Class D Non-Voting
Common Stock; and

                        (iv) warrants to purchase 485,333 shares of Bentley's
Class B Non-Voting Common Stock to be issued in accordance with the Joinder to
the Securities Purchase Agreement.

The shares of capital stock and the warrants to purchase shares of capital stock
to be issued and sold by Bentley at the Effective Time pursuant to this Section
2.6(a) collectively are referred to as the "BENTLEY SECURITIES."

                  (b) At the Effective Time, all of the outstanding shares of
Company Common Stock owned by Bentley shall be cancelled.

                  (c) At the Effective Time, each of the then outstanding
options held by Company employees to purchase Company Common Stock shall by
virtue of the Merger and at the Effective Time, and without any further action
on the part of any holder thereof, be assumed by Bentley and converted into an
option to purchase, under Bentley's 1997 Stock Option Plan, that number of
shares of Bentley Class B Common Stock determined by multiplying the number of
shares of Company Common Stock subject to such option at the Effective Time by
1.4667, at an exercise price per share equal to the exercise price per share of
such option immediately prior to the Effective Time divided by 1.4667. If the
foregoing calculation results in an option being exercisable for a fraction of a
share of Bentley Class B Common Stock, then the number of shares of Bentley
Class B Common Stock subject to such option shall be rounded up to the nearest
whole number of shares. The term, exercisability, vesting schedule, status as an
"Incentive Stock Option" under Section 422 of the Code, if applicable, and all
other terms and conditions of stock options issued pursuant to this Section
2.6(c) will to the extent permitted by law and otherwise reasonably practicable
remain unchanged. Continuous employment with the Company shall be credited to
the optionees for purposes of determining the vesting of the number of shares of
Bentley Class B Common Stock subject to exercise under the optionees' converted
stock options after the Effective Time, and all optionees who have fully vested
options to purchase shares of capital stock of Geopak immediately prior to the
Effective Time will receive fully vested options to purchase shares of Bentley
Class B Common Stock in accordance with the conversion ratio set forth above.

      2.7 Exchange of Certificates. At the Closing, immediately after the
Effective Time of the Merger, all of the Stockholders shall surrender to the
Surviving Corporation all of the outstanding certificates theretofore
representing shares of Company Common Stock in exchange for the Merger
Consideration payable to the Stockholders at Closing. Until such certificates
are surrendered, outstanding certificates formerly representing shares of
Company Common Stock shall be deemed for all purposes as evidencing the right to
receive the Merger Consideration into


                                     - 8 -
<PAGE>

which such shares have been converted as though said surrender and exchange had
taken place. In no event will a holder of shares of Company Common Stock be
entitled to interest on the Merger Consideration issuable in respect of such
shares.

      2.8 Restricted Securities.

                  (a) The Bentley Securities to be issued pursuant to this
Agreement and the Securities Purchase Agreement have not been, and, except as
contemplated by the Registration Rights Agreement, will not be, registered under
the Securities Act, and will be issued in a transaction that is exempt from the
registration requirements of the Securities Act. Until such Bentley Securities
are registered and sold under the Securities Act, they will be "restricted
securities" under the federal securities laws and cannot be offered or resold
except pursuant to registration under the Securities Act or an available
exemption from registration.

                  (b) All certificates representing such Bentley Securities
shall bear, in addition to any other legends required under applicable
securities laws, the following legend and such other legends as are required by
the Transaction Documents:

      The shares represented by this certificate have not been registered under
the Securities Act of 1933, as amended, and may not be transferred except
pursuant to registration under the Securities Act or pursuant to an available
exemption from registration.

      2.9 Allocation of Consideration. The Merger Consideration shall be
allocated among the Stockholders in proportion to the number of shares of
Company Common Stock owned by each such Stockholder at the Effective Time;
provided, however, that no fraction of a share of any Bentley Securities will be
issued.

      2.10 Closing. The closing of the transactions contemplated by this
Agreement ("CLOSING") shall take place at the offices of Drinker Biddle & Reath
LLP, Eighteenth and Cherry Streets, Philadelphia, Pennsylvania 19103, or at such
other location as the parties may agree, on September 18, 2001, or on such other
date that the Parties may agree. The date on which the Closing actually occurs
is referred to herein as the "CLOSING DATE."

      2.11 Transactions at Closing. At the Closing:

                  (a) The Stockholders shall surrender certificates representing
Company Common Stock pursuant to Section 2.7, and the Company and the
Stockholders shall deliver to Bentley and the Surviving Corporation such
documents, instruments and certificates as are required by this Agreement to be
delivered by them.

                  (b) Bentley shall deliver to the Company and Stockholders:

                        (i) the Merger Consideration allocated pursuant to
Section 2.9; and

                        (ii) such documents, instruments and certificates as are
required by this Agreement to be delivered by Bentley and Merger Sub.

               REPRESENTATIONS AND WARRANTIES OF THE STOCKHOLDERS

      The Stockholders, jointly and severally, hereby represent and warrant to
Bentley and Merger Sub as follows:

      4.1 Contravention; Validity.

                  (a) The execution, delivery and performance by the
Stockholders of this Agreement and each of the Collateral Documents to which
they are parties, the consummation by the Stockholders of the transactions
contemplated hereby and thereby, and compliance by the Stockholders with all of

which the Stockholders or any of the Company Common Stock may be bound.

                  (b) This Agreement has been duly and validly executed and
delivered by each Stockholder and constitutes the valid and binding obligation
of each such Stockholder (with respect to his or her obligations hereunder),
enforceable against each such Stockholder in accordance with its terms, except
as enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting creditors' rights generally
and except as enforceability may be subject to general principles of equity
(regardless of whether such enforceability is considered in a proceeding in

      4.2 Company Representations. To the best knowledge of each Stockholder,
the representations and warranties of the Company in Article 3 are true,
complete and accurate.


                                     - 11 -
<PAGE>

      4.3 Alienability of Shares.

                  (a) Each Stockholder has the unfettered right to alienate the
shares of Company Common Stock owned by him or her. Each Stockholder will cause
such unfettered alienability of his or her shares of Company Common Stock
(including by way of exclusion thereof from any community property) to remain in
effect until the Closing.

                  (b) Each Stockholder represents that, if married, he or she is
not physically nor legally separated from his or her spouse, is not involved in
divorce proceedings with his or her spouse and that the transactions entered
into pursuant to this Agreement constitute arms' length transactions.

      4.4 Rights and Options. Except as set forth on Schedule 4.4 and for the
rights granted to Bentley under the Option Agreement, there are no options,
warrants, calls or other rights, agreements or commitments relating to the
Company Common Stock owned by each Stockholder, including any right of
conversion or exchange, actually or contingently, under any outstanding security
or other instrument.

      4.5 Securities Law Matters.

                  (a) Each of Gabriel Norona and Francisco Norona is an
"accredited investor" as such term is defined in Rule 501 of Regulation D under
the Securities Act.

                  (b) The principal residence of each of Gabriel Norona,
Francisco Norona, Dean Bowman, Andrew Panayatoff and Orestes Norat is located in
the State of Florida and the principal residence of Robert Cormack is located in
Australia. No Stockholder has received any communications from Bentley or its
Representatives regarding his investment in the Bentley Securities at any
location other than in the state or jurisdiction of his principal residence. At
all times during the negotiation of this Agreement and the related transactions,
each Stockholder has been represented by Gabriel Norona, as his purchaser
representative, and Norman Malinski, P.A., as his counsel.

                  (c) (i) The Bentley Securities will be acquired by each
Stockholder for investment for the Stockholder's own account, and not with a
view to the sale or distribution of any part thereof in violation of applicable
Federal and state securities laws, and (ii) no Stockholder has any current
intention of selling, granting participation in or otherwise distributing the
same in violation of applicable Federal and state securities laws.

                  (d) Each Stockholder understands that the Bentley Securities
will not be registered under the Securities Act or any state securities law on
the basis that the sale provided for in this Agreement and the issuance of the
Bentley Securities hereunder is exempt from registration under the Securities
Act or any state securities law. Except as required by the Registration Rights
Agreement, Bentley shall not be obligated to register the Bentley Securities
under the Securities Act or any state securities law.

                  (e) Each Stockholder understands that the Bentley Securities
will bear a restrictive legend prohibiting transfers thereof except in
compliance with applicable Federal


                                     - 12 -
<PAGE>

and state securities laws and will not be transferred of record except in
compliance therewith. Bentley may require, as a condition to transferring the
Bentley Securities, an opinion of counsel satisfactory to it that such transfer
complies with applicable Federal and state securities laws. Stop transfer
instructions will be issued to Bentley's transfer agent, if any, with respect to
the Bentley Securities or, if Bentley acts as its own transfer agent, Bentley
will make a notation on its records concerning these restrictions on transfer.

                  (f) Each Stockholder understands that unless previously
registered with the Securities and Exchange Commission, the Bentley Securities
may not be sold, transferred or otherwise disposed of without registration under
the Securities Act or an exemption therefrom, and that in the absence of an
effective registration statement covering the Bentley Securities or an available
exemption from registration under the Securities Act, the Bentley Securities
must be held indefinitely. In particular, each Stockholder is aware that the
Bentley Securities may not be sold pursuant to Rule 144 promulgated under the
Securities Act ("RULE 144") unless all of the conditions of that Rule are met.
Among the current conditions for use of Rule 144 by certain holders is the
availability to the public of current information about Bentley. Such
information is not now available.

                  (g) Each Stockholder (i) can afford to bear the economic risk
of holding the unregistered Bentley Securities for an indefinite period of time,
has no need for liquidity in any Bentley Securities he or she may hold, and has
adequate means for providing for his or her current needs and contingencies,
(ii) can afford to suffer a complete loss of his or her investment in the
Bentley Securities, and (iii) understands and has taken cognizance of all risk
factors related to the receipt of the Bentley Securities. Each Stockholder's
overall commitment to investments which are not readily marketable is not
disproportionate to his or her net worth and his investment in Bentley
Securities will not cause such overall commitment to become excessive. Each
Stockholder has such knowledge and experience in business and financial matters
that he or she is capable of evaluating Bentley and the activities thereof and
the risks and merits of investment in the Bentley Securities, of making an
informed investment decision thereon and of protecting his or her interests in
connection with the transaction.

                  (h) Each Stockholder (i) is familiar with the business and
financial condition, properties, operations and prospects of Bentley, (ii) has
received and carefully reviewed and evaluated the Bentley Information Statement
dated July 31, 2001 and the supplement thereto dated August 15, 2001
(collectively, the "INFORMATION STATEMENT"), which have been provided by Bentley
to the Stockholders, including the "Risk Factors" set forth therein, and (iii)
has been given, through his or her Representatives, full access to all material
information concerning the condition, properties, operations and prospects of
Bentley, including, without limitation, all material books of Bentley and
contracts and documents relating to the transactions contemplated hereby. Each
Stockholder and his or her Representatives have had an opportunity to ask
questions of, and to receive information from, Bentley and persons acting on its
behalf concerning the terms and conditions of his or her investment in the
Bentley Securities and to obtain any additional information necessary to verify
the accuracy of the information and data received by him or her. Neither the
Stockholders nor their Representatives have been furnished any offering
literature other than the Information Statement and the documents attached as
exhibits thereto, and the Stockholders and their Representatives have relied or
will


                                     - 13 -
<PAGE>

rely only on the information contained in the Information Statement and its
exhibits and such other information as is described in this subparagraph (h),
furnished or made available to them by Bentley.

                  (i) Each Stockholder acknowledges that at no time has there
been any representation, guarantee or warranty to him or her by any
broker-dealer, Bentley, their agents or employees, or any other person,
expressly or by implication, concerning any of the following:

                        (i) the approximate or exact length of time that the
Stockholder will be required to retain ownership of Bentley Securities;

                        (ii) the percentage of profit or amount of, or type of
consideration, profit or loss to be realized, if any, as a result of an
investment in Bentley Securities; or

                        (iii) that the past performance or experience of Bentley
will in any way indicate the predictable results of the ownership of Bentley
Securities.

      4.6 Transactions with Affiliates. Except as disclosed in Schedule 4.6, the
Company is not a party to any contract or agreement with any Stockholder, any
other Affiliate or any Affiliate of any Stockholder.

      4.7 Stock Ownership. Each Stockholder is the owner of record and the
beneficial owner of that number of shares of Company Common Stock set forth
opposite his or her name in Schedule 4.7, free and clear of all Encumbrances.

      4.8 Capital Stock. The authorized capital stock of the Company is as set
forth on Schedule 4.8. The issued and outstanding capital stock is owned of
record and beneficially by the Stockholders and by Bentley in the proportions
set forth in Schedule 4.8 hereto. All such outstanding shares of capital stock

      4.18 Employee Benefit Plans; Employment Matters.

                  (a) Schedule 4.18(a) hereto lists each "employee pension
benefit plan", as such term is defined in Section 3(2) of ERISA (each, a
"PENSION PLAN"), and each "employee welfare benefit plan", as such term is
defined in Section 3(1) of ERISA (together with the Pension Plans, the "PLANS")
which is maintained by the Company or to which the Company contributes and which
is subject to ERISA, excluding any Plan which is a multi-employer plan as such
term is defined in Section 3(37) of ERISA. Each Pension Plan that is intended to
be qualified under Section 401(a) of the Code (i) has received a favorable
determination letter from the Internal Revenue Service and the Company is not
aware of any circumstances likely to result in revocation of any such favorable
determination letter and (ii) has been amended to comply with the Tax Reform Act
of 1986 and subsequent laws. Each Plan has complied in all material respects
with the applicable provisions of ERISA and the Code. The Company has not
engaged in any transaction with respect to any Plan which, assuming the taxable
period of such transaction expired as of the date of this Agreement, could
result in any taxes or penalties on prohibited transactions under Section 4975
of the Code or under Section 502(i) of ERISA, in an amount that would reasonably
be expected to have a Material Adverse Effect.

                  (b) No Pension Plan has an "accumulated funding deficiency",
as such term is defined in Section 302 of ERISA and Section 412 of the Code
(whether or not waived). The Company had not incurred any liability to the
Pension Benefit Guaranty Corporation under Title IV of ERISA, other than for the
payment of premiums, all of which have been paid when due. No notice of a
"reportable event," within the meaning of Section 4043 of ERISA for which the
30-day reporting requirement has not been waived, has been required to be filed
for any Pension Plan within the 12-month period ending on the date hereof. The
Company has not incurred a partial or complete withdrawal from any Plan that is
a multi-employer plan, other than a withdrawal that would result in de minimis
liability not in excess of the maximum amount subject to reduction under Section
4209 of ERISA.

                  (c) Except as set forth on Schedule 4.18(c), under each
Pension Plan that is a "single employer plan," within the meaning of Section
4001(a)(15) of ERISA, as of the last day of the most recent plan year ended
prior to the date hereof, the actuarially determined present value of "benefit
liabilities," within the meaning of Section 4001(a)(16) of ERISA (as determined
on the basis of actuarial assumptions contained in the Plan's most recent
actuarial valuation), did not exceed the then current value of the assets of
such Plan. There has been no material change in the financial condition of such
Plan since the last day of the most recent plan year.

                  (d) The Company has no obligations for retiree health and life
benefits under any Plan, except as set forth on Schedule 4.18(d). Subject to the
provisions of the Stockholders' Agreement, the Company may amend or terminate
any such Plan, under the terms of such Plan, without incurring any material
liability thereunder.

                  (e) None of the Plans provides for the payment of separation,
severance, termination or similar-type benefits to any person or obligates the
Company to pay separation, severance, termination or similar-type benefits
solely or partially as a result of any


                                     - 19 -
<PAGE>

transaction contemplated by this Agreement or as a result of a "change in
control", within the meaning of such term under Section 280G of the Code.
Neither the execution and delivery of this Agreement nor the consummation of the
transactions contemplated hereby, either alone or together with another event,
will (i) result in any payment (including, without limitation, severance,
unemployment compensation, golden parachute, forgiveness of indebtedness or
otherwise) becoming due under any Plan, (ii) increase any benefits otherwise
payable under any Plan or other arrangement, (iii) result in the acceleration of
the time of payment, vesting or funding of any benefits, or (iv) affect in any
respects any Plan's current treatment under any Legal Requirements including any
tax or social contribution law.

                  (f) There are no collective bargaining agreements applicable
to any Persons employed by the Company, and the Company has no duty to bargain
with any labor organization with respect to any such Person. There are not
pending any unfair labor practice charges against the Company, nor is there any
demand for recognition, or any other request or demand from a labor organization
for representative status with respect to any person employed by the Company.

                  (g) The Company is in substantial compliance with all
applicable Legal Requirements respecting employment conditions and practices,
has withheld all amounts required by any applicable Legal Requirements or
Contracts to be withheld from the wages or salaries of its employees, and is not
liable for any arrears of wages or any Taxes or penalties for failure to comply
with any of the foregoing.

                  (h) The Company has not engaged in any unfair labor practice
within the meaning of the National Labor Relations Act and has not violated any
Legal Requirement prohibiting discrimination on the basis of race, color,
national origin, sex, religion, age, marital status, or handicap in its
employment conditions or practices. There are not pending or, to any
Stockholder's knowledge, threatened unfair labor practice charges or
discrimination complaints relating to race, color, national origin, sex,
religion, age, marital status, or handicap against the Company in, by or before
any Governmental Authority.

                  (i) There are no existing or, to any Stockholder's knowledge,
threatened, labor strikes, disputes, grievances or other labor controversies
affecting the Company. There are no pending or, to any Stockholder's knowledge,
threatened arbitration proceedings under any Contract.

                  (j) The Company is not a party to any employment agreement or
arrangement, written or oral, relating to its employees which cannot be
terminated at will by the Company.

                  (k) Schedule 4.18(k) sets forth a true and complete list of
the names, titles and rates of compensation of the eighteen most highly
compensated employees of the Company.

      4.19 Customers. As of the date hereof, none of the twenty (20) customers
to whom the Company made the most sales (measured by gross revenues) during the
fiscal year ended


                                     - 20 -
<PAGE>

December 31, 2000 and/or during 2001 fiscal year-to-date has cancelled or
otherwise terminated prior to the expiration of the contract term, or, to the
Stockholders' knowledge, made any written threat to the Company to cancel or
otherwise terminate its relationship with the Company.

      4.20 Brokers or Finders. No broker or finder has acted directly or
indirectly for the Stockholders or any of their Affiliates in connection with
the transactions contemplated by this Agreement. Neither the Stockholders nor
any of their Affiliates has incurred any obligation to pay any brokerage or
finder's fee or other commission in connection with the transactions
contemplated by this Agreement.

      4.21 Full Disclosure. Neither this Agreement (including all Exhibits and
Schedules hereto and any other agreements or documents delivered on the Closing
Date), nor any written report or Financial Statement delivered or furnished to
Bentley by or on behalf of the Stockholders pursuant to or in connection with
this Agreement, or the transactions contemplated hereby, contains any untrue
statement of a material fact or omits to state a material fact necessary to make
the statements contained herein or therein not misleading in light of the
circumstances under which they were made. There is no fact known to the
Stockholders that has not been disclosed to Bentley in writing that has or could
reasonably be expected to have a Material Adverse Effect.

      The Parties agree as follows with respect to the period following Closing:

continuing employees of the Surviving Corporation and all employees of the
Company engaged directly by Bentley shall be eligible for employee benefits

benefits that the Company had been providing to such continuing employees
immediately prior to the Effective Time, and (ii) Bentley shall grant all
continuing employees of the Surviving Corporation credit for service (to the

                                     - 25 -

      8.2 Tax Matters.

                  (a) Bentley shall cause the Company to prepare and file all
Returns required by law of the Company for all taxable periods ending on or
before the Closing Date (the "PRE-CLOSING PERIODS") and the Stockholders shall
be responsible for, and indemnify Bentley against, the payment of all income,
franchise or similar Taxes of the Company attributable to such periods, whenever
incurred or assessed, in excess of the amounts reflected for Tax liabilities in
the Financial Statements or, in the case of Taxes accruing after the periods
covered by the Financial Statements, to the extent such Taxes were not incurred
in the ordinary course of business.

                  (b) The Returns for the Pre-Closing Periods shall be made
available to the Stockholders no less than 21 calendar days prior to the filing
thereof with the appropriate Governmental Authority for review by the
Stockholders. From and after the Closing Date, Bentley and the Company, on the
one hand, and the Stockholders, on the other hand, shall make available to the
other, as reasonably requested, all information, records or documents relating
to the Tax liabilities of the Company for all periods ending on or prior to the
Closing Date, and will preserve such information, records or documents until the
expiration of any applicable statute of limitations or extensions thereof.

                  (c) Bentley shall notify the Stockholders of any pending or
threatened federal, state, local or foreign tax audit, examinations or
assessments which may affect any tax liability for which the Stockholders are
liable. The Stockholders shall have the sole right to conduct any tax audit or
administrative or court proceeding relating to a potential liability for such
taxes and shall bear all costs and expenses of such audit or examination.
Bentley shall not settle any tax claim for which the Stockholders may be liable
without prior written consent of Stockholders which consent shall not be
unreasonably withheld.

                  (d) Neither Bentley nor the Stockholders shall take any
action, and Bentley shall cause the Company to refrain from taking any action,
that would adversely affect the treatment of the Merger as a reorganization
within the meaning of Section 368(a)(2)(D) of the Code.

      8.3 Non-Competition.

                  (a) As an inducement to Bentley, and recognizing that Bentley
would not have entered into this Agreement and the Collateral Documents without
the Non-Competition Covenants, no Stockholder nor any Affiliate thereof shall,
directly or indirectly, until two (2) years from the Closing Date:

                        (i) engage, anywhere in the Territory, in developing,
publishing, marketing, selling or supporting software useful in any civil
engineering market (including, without limitation, the transportation, road,
bridge, site and subdivision development, and survey and structures markets)
that is substantially similar to or in competition with any software product
offered by Bentley, the Company, the Surviving Corporation or their Affiliates
(collectively, the "Bentley Entities") or planned to be offered by any Bentley
Entity, or to


                                     - 26 -
<PAGE>

provide anywhere in the Territory any service substantially similar to or in
competition with any service offered by any Bentley Entity;

                        (ii) be or become a shareholder, director, partner,
owner, officer, employee or agent of, or consultant to, or give financial or
other assistance to, Autodesk, Inc. or Intergraph Corporation or any other
Person engaged in, or considering in engaging in, any such activities other than
the Bentley Entities following the Effective Time; provided, however, that
nothing herein shall prohibit such Stockholder from owning, as a passive
investor, up to one percent (1%) of the outstanding publicly traded stock of any
corporation so engaged;

                        (iii) seek, in competition with the Bentley Entities, to
procure orders from, purchase any product from or do business with, any customer
or supplier thereof;

                        (iv) solicit, or contact with a view to the engagement
or employment of, an employee of the Bentley Entities;

                        (v) seek to contract with or engage (in such a way as to
adversely affect or interfere with the Bentley Entities) any Person who has been
contracted with or engaged to manufacture, assemble, supply or deliver products,
goods, materials or services to the Bentley Entities; or

                        (vi) engage in or participate in any effort or act to
induce any of the customers, associates, consultants, partners, or employees of
the Bentley Entities to take any action which might be disadvantageous to the
Bentley Entities.

The foregoing covenants are collectively referred to herein as the
"NON-COMPETITION COVENANTS."

                  (b) Each of the Stockholders agrees that a violation of any of
the Non-Competition Covenants will cause irreparable damage to the Bentley
Entities and that it is and will be impossible to estimate or determine the
damage that will be suffered by the Bentley Entities in the event of a breach by
a Stockholder of any such covenant. Therefore, each Stockholder further agrees
that the Bentley Entities and/or any non-violating Stockholder shall be entitled
to an injunction out of any court of competent jurisdiction, restraining any
further violation of such covenant or covenants by such Stockholder, his or her
employer, employees, partners, agents or other associates, or any of them, such
right to an injunction to be cumulative and in addition to whatever other
remedies the Bentley Entities may have.

                  (c) The invalidity of any one or more of the provisions
contained in this Section 8.3 shall not affect the enforceability of the
remaining portions of this Section. If one or more of the provisions contained
in this Section shall be invalid, this Section shall be construed as if such
provision had not been inserted, and if such invalidity should be caused by the
length of any period of time or the size of any area set forth in this Section,
such period of time or such area, or both, shall, without need of further action
by any party hereto, be deemed to be reduced to a period or area that will cure
such invalidity.

<PAGE>

                  (d) The period set forth in Section 8.3(a) shall be extended
by the duration of any violation of such provision by a Stockholder with respect
to such violating Stockholder.

                                   ARTICLE 9

                                 INDEMNIFICATION

      9.1 Survival of Representations and Warranties. The representations and
warranties contained in this Agreement shall survive the Effective Time. Neither
the period of survival nor the liability of a Party with respect to such Party's
representations and warranties shall be reduced by any investigation made at any
time by or on behalf of another Party. The covenants and agreements contained in
this Agreement or any certificate or other writing required to be delivered
pursuant hereto shall survive the Effective Time to the extent specifically
contemplated by the terms thereof.

      9.2 Indemnification by Stockholders and Company. Bentley and its
Affiliates (including, after the Effective Time, the Surviving Corporation),
officers, directors, stockholders, employees, agents, successors and assigns
(collectively, the "BENTLEY INDEMNIFIED PARTIES"), shall be indemnified and held
harmless by the Company and the Stockholders, jointly and severally, for any and
all liabilities, losses, damages, claims, costs and expenses, interest, awards,
judgments and penalties (including, without limitation, reasonable attorneys'
and consultants' fees and expenses and other costs of defending, investigating
or settling claims) actually suffered or incurred by them (including, without
limitation, in connection with any action brought or otherwise initiated by any
of them) (hereinafter, "DAMAGES"), arising out of or resulting from:

                  (a) any inaccuracy in or the breach of any representation or
warranty made by the Company or the Stockholders in this Agreement;

                  (b) the breach or non-fulfillment of any covenant or agreement
made by the Company or the Stockholders in this Agreement;

                  (c) any liability or other obligation of the Company existing
on the Closing Date and not disclosed in the Financial Statements, other than
current liabilities incurred in the ordinary course of business consistent with
past practice;

                  (d) any infringement of any trademark, copyright, patent or
other proprietary or intellectual property right of any Person; and

                  (e) all liability of the Company or the Stockholders for Taxes
that are due or accrue before the Closing Date.

      9.3 Indemnification by Bentley. The Stockholders and their respective
Affiliates (collectively, the "STOCKHOLDER INDEMNIFIED PARTIES"), shall be

                  (b) the breach or non-fulfillment of any covenant or agreement
made by Bentley or Merger Sub in this Agreement.

      9.4 Stockholders' Representative. The Stockholders hereby appoint Gabriel
Norona (such person and any successor or successors being the "STOCKHOLDERS'
REPRESENTATIVE"), and Gabriel Norona shall act as, the representative of the
Stockholders, with full authority to act on behalf of the Stockholders and to
take any and all actions required or permitted to be taken by the Stockholders'
Representative under this Agreement, with respect to any claims (including the
settlement thereof) made by Bentley or the Stockholders for indemnification
pursuant to this Article 9. The Stockholders shall be bound by all actions taken
by the Stockholders' Representative in his capacity thereof. The Stockholders'
Representative shall promptly, and in any event within five Business Days,
provide written notice to the Stockholders of any action taken on their behalf
by the Stockholders' Representative pursuant to the authority delegated to the
Stockholders' Representative under this Section 9.4. The Stockholders'
Representative shall at all times act in his capacity as Stockholders'
Representative in a manner that the Stockholders' Representative believes to be
in the best interest of the Stockholders. The Stockholders' Representative shall
not be liable to any person for any error of judgment, or any action taken,
suffered or omitted to be taken, under this Agreement, except in the case of his
gross negligence, bad faith or willful misconduct. The Stockholders'
Representative may consult with legal counsel, independent public accountants
and other experts selected by him and shall not be liable for any action taken
or omitted to be taken in good faith by him in accordance with the advice of
such counsel, accountants or experts. The Stockholders' Representative shall not
have any duty to ascertain or to inquire as to the performance or observance of
any of the terms, covenants or conditions of this Agreement. As to any matters
not expressly provided for in this Agreement, the Stockholders' Representative
shall not be required to exercise any discretion or take any action.

this Agreement and (b) the Stockholders' Representative shall not, in any
manner, exercise, or seek to exercise, any voting power whatsoever with respect
to shares of capital stock of the Company or Bentley now or hereafter owned of
record or beneficially by any Stockholder unless the Stockholders'

such Stockholder. In all matters relating to this Article 9, the Stockholders'
Representative shall be the only party entitled to assert the rights of the
Stockholders, and the Stockholders' Representative shall perform all of the
obligations of the Stockholders hereunder. Bentley shall be entitled to rely on
all statements, representations and decisions of the Stockholders'
Representative.

      9.5 Matters Involving Third Parties.

                  (a) If any third party shall notify either Bentley, the
Surviving Corporation or the Stockholders (the "INDEMNIFIED PARTY") with respect
to any matter (a "THIRD PARTY CLAIM") that may give rise to a claim for
indemnification against the other (the


                                     - 29 -
<PAGE>

"INDEMNIFYING PARTY") under this Article, then the Indemnified Party shall
promptly notify the Indemnifying Party thereof in writing; provided, however,
that no delay on the part of the Indemnified Party in notifying any Indemnifying
Party shall relieve the Indemnifying Party from any obligation hereunder unless
(and then solely to the extent) the Indemnifying Party thereby is prejudiced.

                  (b) Any Indemnifying Party shall have the right to defend the
Indemnified Party against the Third Party Claim with counsel of the Indemnifying
Party's choice reasonably satisfactory to the Indemnified Party so long as: (i)
the Indemnifying Party notifies the Indemnified Party in writing (within 30 days
after the Indemnified Party has given notice of the Third Party Claim) that the
Indemnifying Party will indemnify the Indemnified Party from and against the
entirety of any adverse consequences the Indemnified Party may suffer resulting
from, arising out of, relating to, in the nature of or caused by the Third Party
Claim; (ii) the Indemnifying Party provides the Indemnified Party with evidence
acceptable to the Indemnified Party that the Indemnifying Party will have the
financial resources to defend against the Third Party Claim and fulfill its
indemnification obligations hereunder; (iii) settlement of, or an adverse
judgment with respect to, the Third Party Claim is not, in the good faith
judgment of the Indemnified Party, likely to establish a precedential custom or
practice adverse to the continuing business interests of the Indemnified Party;
and (iv) the Indemnifying Party conducts the defense of the Third Party Claim
actively and diligently.

                  (c) So long as the Indemnifying Party is conducting the
defense of the Third Party Claim in accordance with subsection (b) above: (i)
the Indemnified Party may retain separate co-counsel at its sole cost and
expense and participate in the defense of the Third Party Claim; (ii) the
Indemnified Party shall not consent to the entry of any judgment or enter into
any settlement with respect to the Third Party Claim without the prior written
consent of the Indemnifying Party; and (iii) the Indemnifying Party shall not
consent to the entry of any judgment or enter into any settlement with respect
to the Third Party Claim without the prior written consent of the Indemnified
Party.

                  (d) If any of the conditions in subsection (c) above is not or
no longer satisfied, however: (i) the Indemnified Party may defend against, and
consent to the entry of any judgment or enter into any settlement with respect
to, the Third Party Claim in any manner it reasonably may deem appropriate (and
the Indemnified Party need not consult with, or obtain any consent from, any
Indemnifying Party in connection therewith); (ii) the Indemnifying Party shall
reimburse the Indemnified Party promptly and periodically for the costs of
defending against the Third Party Claim (including reasonable attorneys' fees
and expenses); and (iii) the Indemnifying Party shall remain responsible for any
adverse consequences the Indemnified Party may suffer resulting from, arising
out of, relating to, in the nature of or caused by the Third Party Claim to the
fullest extent provided in this Article 9.

the respective Releasees arising contemporaneously with or prior to the Closing
or on account of or arising out of any matter, cause or event occurring
contemporaneously with or prior to the Closing, including, but not limited to,
any rights under federal or state securities laws and any rights to

Any Party may change the address to which notices are required to be sent by
giving notice of such change in the manner provided in this Section.

      10.4 Headings. The Article and Section headings of this Agreement are for
convenience only and shall not constitute a part of this Agreement or in any way
affect the meaning or interpretation thereof.

      10.5 Choice of Law; Exclusive Jurisdiction.

                  (a) This Agreement and the rights of the Parties under it
shall be governed by and construed in all respects in accordance with the laws
of the State of Delaware, without giving effect to any choice of law provision
or rule (whether of the State of Delaware or any other jurisdiction that would
cause the application of the laws of any jurisdiction other than the State of
Delaware).

                  (b) Each party hereto irrevocably and unconditionally consents
and submits to the non-exclusive jurisdiction of the courts of the State of
Delaware and of the United States of America located in the State of Delaware
for any actions, suits or proceedings arising out of or relating to this
Agreement and the transactions contemplated hereby, and further agrees that
service of any process, summons, notice or document by U.S. registered or
certified mail to


                                     - 33 -
<PAGE>

the Company or Bentley, as the case may be, at the addresses set forth in
Section 10.3 hereof, shall be effective service of process for any action, suit
or proceedings brought against such party in such court. Each party hereto
hereby irrevocably and unconditionally waives any objection to the laying of
venue of any action, suit or proceeding arising out of this Agreement or the
transactions contemplated hereby, in the courts of the State of Delaware located
in Wilmington, Delaware or the United States of America located in Wilmington,
Delaware, and hereby further irrevocably and unconditionally waives and agrees
not to plead or claim in any such court that any such action, suit or proceeding
brought in any such court has been brought in any inconvenient forum.

      10.6 Rights Cumulative. All rights and remedies of each of the Parties
under this Agreement shall be cumulative, and the exercise of one or more rights
or remedies shall not preclude the exercise of any other right or remedy
available under this Agreement or applicable law.

      10.7 Further Actions. The Parties shall execute and deliver to each other,
from time to time at or after Closing, for no additional consideration and at no
additional cost to the requesting party, such further assignments, certificates,
instruments, records, or other documents, assurances or things as may be
reasonably necessary to give full effect to this Agreement and to allow each
party fully to enjoy and exercise the rights accorded and acquired by it under
this Agreement.

      10.8 Counterparts. This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

      10.9 Entire Agreement. This Agreement (including the Exhibits, Schedules
and any other documents, instruments and certificates referred to herein, which
are incorporated in and constitute a part of this Agreement) contains the entire
agreement of the Parties and supersedes all prior oral or written agreements,
understandings and representations to the extent that they relate in any way to
the subject matter hereof, including the Letter of Intent.

      10.10 Amendments and Waivers. No amendment of any provision of this
Agreement shall be valid unless the same shall be in writing and signed by the
Parties. No waiver by any party of any default, misrepresentation or breach of
warranty or covenant hereunder shall be valid unless the same shall be in
writing and signed by the Person against whom its enforcement is sought, and no
such waiver whether intentional or not, shall be deemed to extend to any prior
or subsequent default, misrepresentation or breach of warranty or covenant
hereunder or affect in any way any rights arising by virtue of any prior or
subsequent such occurrence.

      10.11 Construction. The Parties have participated jointly in the
negotiation and drafting of this Agreement. If an ambiguity or question of
intent or interpretation arises, this Agreement shall be construed as if drafted
jointly by the parties and no presumption or burden of proof shall arise
favoring or disfavoring any party by virtue of the authorship of any of the
provisions of this Agreement. Any reference to any federal, state, local, or
foreign statute or law shall be deemed also to refer to all rules and
regulations promulgated thereunder, unless the context requires


                                     - 34 -

otherwise. The word "including" shall mean "including without limitation." The
Parties intend that each representation, warranty, covenant and condition
contained herein shall have independent significance. If any Party has breached
any representation, warranty or covenant contained herein in any respect, the
fact that there exists another representation, warranty or covenant relating to
the same subject matter (regardless of the relative levels of specificity) which
the Party has not breached shall not detract from or mitigate the fact that the
party is in breach of the first representation, warranty or covenant.

      10.12 Disclosure. The terms of this Agreement and the Collateral Documents
are confidential and no Party shall disclose to any Person such existence or
terms without the prior written consent of the other Parties, except that (i)
Bentley may make such disclosure without the consent of any other Party at any
time following the Closing, (ii) any Party may make such disclosure as is
required (in the opinion of its counsel) by applicable law, and (iii) any Party
may make such disclosure to its Representatives and lenders who agree to keep
the terms of this Agreement and the Collateral Documents strictly confidential.
Each of the Parties will be responsible for any damages resulting from the
unauthorized disclosure of the existence or terms of this Agreement or the
Collateral Documents by it or its respective Representatives.
