         through the Exchange Agent, certificates representing the shares of
         Bracknell Common Stock issuable pursuant to Section 2.02 in exchange
         for outstanding Able Shares and Series D Shares. Promptly after the
         Effective Time, Subco will send, or will cause the Exchange Agent to
         send, to each holder of Able Shares or Series D Shares at the
         Effective Time a letter of transmittal for use in such exchange (which
         shall specify that the delivery shall be effected, and risk of loss
         and title shall pass, only upon proper delivery of the certificates
         representing Able Shares or Series D Shares to the Exchange Agent).

                  (b) Each holder of Able Shares or Series D Shares that have
         been converted into a right to receive Bracknell Common Stock, upon
         surrender to the Exchange Agent of a certificate or certificates
         representing such Able Shares or Series D Shares, together with a
         properly completed letter of transmittal covering such Able Shares or
         Series D Shares, will be entitled to receive in exchange therefor that
         number of whole shares of Bracknell Common Stock which such holder has
         the right to receive pursuant to Section 2.02, and the certificate or
         certificates for Able Shares or Series D Shares so surrendered shall
         be cancelled. Until so surrendered, each such certificate shall, after
         the Effective Time, represent for all purposes, only the right to
         receive upon such surrender a certificate representing shares of
         Bracknell Common Stock and cash in lieu of any fractional shares of
         Bracknell Common Stock as contemplated by this Section 2.03 and
         Section 2.05.

                  (c) If any shares of Bracknell Common Stock are to be issued
         to a Person other than the registered holder of Able Shares or Series
         D Shares represented by the certificate or certificates surrendered in
         exchange therefor, it shall be a condition to such issuance that the
         certificate or certificates so surrendered shall be properly endorsed
         or otherwise be in proper form for transfer and that the Person
         requesting such issuance shall pay to the Exchange Agent any transfer
         Tax or other Taxes required as a result of such issuance to a Person
         other than the registered holder of such Able Shares or Series D
         Shares or establish to the satisfaction of the Exchange Agent that
         such Tax has been paid or is not payable.

                  (d) After the Effective Time, there shall be no further
         registration of transfers of Able Shares or Series D Shares. If, after
         the Effective Time, certificates representing Able Shares or Series D
         Shares are presented to the Surviving Corporation, they shall be
         cancelled and exchanged as provided for, and in accordance with the
         procedures set forth, in this Article II.

                  (e) Any shares of Bracknell Common Stock made available to
         the Exchange Agent pursuant to Section 2.03(a) that remain unclaimed
         by the holders of Able Shares or


                                      17
<PAGE>   19

         Series D Shares six months after the Effective Time shall be returned
         to Bracknell, upon demand, and any such holder who has not exchanged
         his Able Shares or Series D Shares in accordance with this Section
         prior to that time shall thereafter look only to Bracknell to exchange
         such Able Shares or Series D Shares. Notwithstanding the foregoing,
         the Surviving Corporation and Bracknell shall not be liable to any
         holder of Able Shares or Series D Shares for any amount paid, or any
         shares of Bracknell Common Stock delivered, to a public official
         pursuant to applicable abandoned property Laws. Any shares of
         Bracknell Common Stock or other amounts remaining unclaimed by holders
         of Able Shares or Series D Shares two years after the Effective Time
         (or such earlier date immediately prior to such time as such amounts
         would otherwise escheat to or become property of any Governmental
         Authority) shall, to the extent permitted by applicable Law, become
         the property of Bracknell free and clear of any claims or interest of
         any Person previously entitled thereto.

                  (f) No dividends or other distributions on shares of
         Bracknell Common Stock shall be paid to the holder of any
         unsurrendered certificates representing Able Shares or Series D Shares
         until such certificates are surrendered as provided in this Section.
         Upon such surrender, there shall be paid, without interest, to the
         Person in whose name the certificates representing the shares of
         Bracknell Common Stock into which such Able Shares or Series D Shares
         were converted are registered, all dividends and other distributions
         paid in respect of such Bracknell Common Stock on a date subsequent
         to, and in respect of a record date after, the Effective Time.

                  SECTION 2.04 Adjustments. If at any time during the period
between the date of this Agreement and the Effective Time, any change in the
outstanding shares of Bracknell Common Stock, Able Shares or Series D Shares
shall occur, including by reason of any reclassification, recapitalization,
stock split or combination, exchange or readjustment of shares, or any stock
dividend thereon with a record date during such period, the Conversion Number
and the Series D Conversion Number shall be appropriately adjusted.

                  SECTION 2.05 Fractional Shares. No fractional shares of
Bracknell Common Stock shall be issued in the Merger. All fractional shares of
Bracknell Common Stock that a holder of Able Shares would otherwise be entitled
to receive as a result of the Merger shall be aggregated and if a fractional
share results from such aggregation, such holder shall be entitled to receive,
in lieu thereof, an amount in cash determined by multiplying the average of the
daily closing sale prices per share of Bracknell Common Stock on The Toronto
Stock Exchange (the "TSE") for the ten trading days next preceding the
Effective Time by the fraction of a share of Bracknell Common Stock to which
such holder would otherwise have been entitled. Alternatively, the Surviving
Corporation shall have the option of instructing the Exchange Agent to
aggregate all fractional shares of Bracknell Common Stock, sell such shares in
the public market and distribute to holders of Able Shares a pro rata portion
of the proceeds of such sale; provided that Bracknell shall pay all transaction
costs associated therewith. No such cash in lieu of fractional shares of
Bracknell Common Stock shall be paid to any holder of Able Shares until
certificates representing such Able Shares are surrendered and exchanged in
accordance with Section 2.03.

                  SECTION 2.06 Dissenting Shares.

                  (a) Notwithstanding any other provisions of this Agreement to
         the contrary, Able Shares and Series D Shares that are outstanding
         immediately prior to the Effective Time and which are held by Able
         stockholders who shall have not voted in favor of the Merger or
         consented thereto in writing and who shall be entitled to and shall
         have demanded properly in writing, appraisal for such shares in
         accordance with the Florida General Corporation Law (collectively, the
         "Dissenting Shares") shall not be converted into or represent the
         right to receive Bracknell Common Stock. Such stockholders instead
         shall be entitled to receive payment of the appraised value of such
         Able Shares or Series D Shares held by them in accordance with the
         provisions of the Florida General Corporation Law, except that all
         Dissenting Shares held by such stockholders, who shall have failed to
         perfect or who effectively shall have withdrawn, forfeited, or lost
         their rights to appraisal of such Able Shares or Series D Shares under
         the Florida General Corporation Law, shall thereupon be deemed to have
         been converted into and to have become exchangeable for, as of the
         Effective Time, the right to receive, without any interest thereon,
         Bracknell Common Stock in the manner provided in Section 2.03 above.

                  (b) Able shall give Bracknell prompt notice of any demands
         for appraisal received by it, withdrawals of such demands, and any
         other instruments served pursuant to the Florida General Corporation
         Law and received by Able and relating thereto. Able shall direct all
         negotiations and proceedings with respect to demands for appraisal
         rights under the Florida General Corporation Law and shall keep
         Bracknell informed regarding the progress thereof.

                                   ARTICLE IV

                     REPRESENTATIONS AND WARRANTIES OF ABLE

                  Able represents and warrants to Bracknell and Subco that:

                  SECTION 4.01 Corporate Existence and Power. Able and each of
its Subsidiaries is a corporation or other entity duly organized, validly
existing and in good standing under the Laws of its jurisdiction of
incorporation or organization, has all requisite power and authority to own,
lease and operate its properties and to carry on its Business as now being
conducted, and is duly qualified and in good standing to do business in each
jurisdiction in which the Business it is conducting, or the operation, ownership
or leasing of its properties, makes such qualification necessary, other than in
such jurisdictions where the failure to so qualify would not have an Able
Material Adverse Effect. For purposes of this Agreement, an "Able Material
Adverse Change" or "Able Material Adverse Effect," means any change or effect,
either individually or in the aggregate, that is or may be reasonably expected
to be materially adverse to the Business, assets, liabilities, properties,
financial condition or results of operations of Able or an Able Significant
Subsidiary. For the purposes of this Agreement, an "Able Significant Subsidiary"
means a Subsidiary of Able which individually accounted for 10% or more of the
total revenues, net income, cash flows from operations or assets of Able and its
Subsidiaries on a consolidated basis in either of Able's previous two fiscal
years. Able has heretofore delivered to Bracknell true and complete copies of
Able's articles of incorporation and bylaws as currently in effect.

                  SECTION 4.02 Corporate Authorization. Able has all requisite
corporate power and authority to enter into this Agreement and to consummate the
transactions contemplated hereby. The execution and delivery of this Agreement
and the consummation of the transactions contemplated hereby have, except for
any required approval by Able's stockholders in connection with the Merger, been
duly authorized by all necessary corporate action on the part of Able. Able's
Board of Directors has authorized Able to enter into this Agreement, has
determined that this Agreement is in the best interests of Able and its
stockholders and has recommended that Able's stockholders vote in favor of the
Merger and the other transactions contemplated hereby. This Agreement has been
duly executed and delivered by Able and constitutes a valid and binding
obligation of Able enforceable in accordance with its terms, subject to
bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium and
similar Laws now or hereafter in effect, affecting creditors' rights and
remedies and to general principles of equity.

                  SECTION 4.03 Governmental Authorization. No consent, approval,
Order or authorization of, or registration, declaration or filing with, or
Permit from, any Governmental Authority is required by or with respect to Able
or any of its Subsidiaries in connection with the execution, delivery and
performance of this Agreement by Able or the consummation of the Merger or other
transactions contemplated hereby, other than (i) compliance with the applicable
requirements of the HSR Act and the Exchange Act, and (ii) the filing of a
certificate of merger with the Secretary of State of the State of Florida,
except where the failure of any action to be taken by any Governmental Authority
or filing to be made would not have an Able Material


                                       20
<PAGE>   22

Adverse Effect or prevent consummation of the Merger or the other transactions
contemplated hereby.

                  SECTION 4.04 Non-Contravention. The execution and delivery of
this Agreement by Able does not, and the consummation of the transactions
contemplated hereby by Able will not, conflict with, or result in any violation
of, or default (with or without notice or lapse of time, or both) under, or give
rise to a right of termination, cancellation or acceleration of any obligation
or the loss of a material benefit under, or the creation of a Lien on assets or
property or right of first refusal with respect to any asset or property (any
such conflict, violation, default, right of termination, cancellation or
acceleration, loss, creation or right of first refusal, a "Violation"), pursuant
to any provision of the articles of incorporation or bylaws of Able or any of
its Subsidiaries or, except as set forth on Schedule 4.04 hereto, or as to which
requisite waivers or consents have been obtained and assuming the consents,
approvals, authorizations or Permits and filings or notifications referred to in
Section 4.03 are duly and timely obtained or made, result in any Violation of
any loan or credit agreement, note, mortgage, indenture, Lease, Benefit
Arrangement or other agreement, obligation, instrument, Permit, concession,
franchise, Order or Law applicable to Able or any of its Subsidiaries or their
respective properties or assets, except for any Violations which would not have
an Able Material Adverse Effect.

                  SECTION 4.05 Capitalization.

                  (a)      The entire authorized capital stock of Able consists
         of (i) 25,000,000 shares of common stock, par value $.001 per share,

         16,374,504 Able Shares are validly issued and outstanding and 5,000
         shares of Series C Convertible Preferred Stock (the "Series C Shares")
         are validly issued and outstanding. Each of the aforesaid shares has
         been validly issued, is fully paid and nonassessable, and has not been

         of the Series D Shares will be validly issued, fully paid,
         nonassessable, and will not be issued in contravention of any
         preemptive rights. Able has also granted options to purchase 3,322,885
         Able Shares (the "Able Stock Options") to the Persons (who are present
         or former officers, directors, employees or advisors), at the exercise
         prices and in the amounts listed on Schedule 4.05(a)(i), of which
         2,260,000 were granted outside of Able's Stock Option Plan and
         1,062,885 were granted under Able's Stock Option Plan. Able has also
         issued warrants and other options to purchase 4,777,031 Able Shares to
         other Persons, at the exercise prices and in amounts listed on Schedule
         4.05(a)(ii). Except as set forth in Schedules 4.05(a)(i) and
         4.05(a)(ii) hereto, no options, warrants or other rights to acquire,
         sell, or issue shares of capital stock of Able are outstanding, and
         except as disclosed in Schedule 4.05(a)(iii), between the date hereof
         and the Effective Time, no shares of capital stock of Able and no such
         options, warrants or rights will be issued. Except as set forth in
         Schedule 4.05(a)(iv), Able has not issued, granted or awarded any

<PAGE>   23

                  (b)      No bonds, debentures, notes or other indebtedness
         having the right to vote (or convertible into securities having the
         right to vote) on any matters on which stockholders may vote ("Voting
         Debt") that were issued by Able are outstanding. Except as set forth in
         this Section 4.05, there are outstanding (A) no shares of capital
         stock, Voting Debt or other voting securities of Able, (B) no
         securities of Able or any Subsidiary of Able convertible into or
         exchangeable for shares of capital stock, Voting Debt or other voting
         securities of Able or any Subsidiary of Able, and (C) no options,
         warrants, calls, rights (including preemptive rights), commitments or

         cause to be issued, delivered, sold, purchased, redeemed or acquired,
         additional shares of capital stock or any Voting Debt or other voting
         securities of Able or of any Subsidiary of Able or obligating Able or
         any Subsidiary of Able to grant, extend or enter into any such option,
         warrant, call, right, commitment or agreement.

                  (c)      Except as listed in Schedule 4.05(c), there are not
         as of the date hereof and there will not be at the Effective Time any
         stockholder agreements, voting trusts or other agreements or
         understandings to which Able is a party or by which it is bound
         relating to the voting of any shares of the capital stock of Able which
         will limit in any way the granting of proxies by or on behalf of or
         from, or the casting of votes by, Able stockholders with respect to the
         Merger. There are no restrictions on the ability of Able to vote the
         stock of any of its Subsidiaries.

                  SECTION 4.06 Subsidiaries. Schedule 4.06(i) sets forth the

Able. The authorized and issued and outstanding shares of capital stock of each
Subsidiary of Able are set forth on Schedule 4.06(ii). Except as set forth in
Schedule 4.06(iii), all of the outstanding capital stock of, or other ownership
interests in, each Subsidiary of Able is owned by Able, directly or indirectly,
free and clear of any Lien and free of any other limitation or restriction
(including any restriction on the right to vote, sell or otherwise dispose of
such capital stock or other ownership interests).

                  SECTION 4.07 SEC Filings.

                  (a)      Able has delivered to Bracknell (i) Able's annual
         report on Form 10-K for the fiscal year ended October 31, 1999 (amended
         May 26, 2000) (the "Able 10-K"), (ii) its quarterly reports on Form

         reference (the filings referred to in clauses (i) through (v) above and

                                       22
<PAGE>   24

                  (b)      As of its filing date or with respect to any proxy
         statements, as of the date it was first mailed to Able stockholders,
         each such report or statement filed pursuant to the Exchange Act
         complied as to form in all material respects with the requirements of
         the Exchange Act and did not contain any untrue statement of a material
         fact or omit to state any material fact necessary in order to make the
         statements made therein, in the light of the circumstances under which
         they were made, not misleading.

                  (c)      Each such registration statement and any amendment
         thereto filed pursuant to the Securities Act of 1933, as of the date
         such statement or amendment became effective, complied as to form in
         all material respects with the Securities Act of 1933 and did not
         contain any untrue statement of a material fact or omit to state any
         material fact required to be stated therein or necessary to make the
         statements therein not misleading.

                  SECTION 4.08 Financial Statements. The audited consolidated
financial statements and unaudited consolidated interim financial statements of
Able and its consolidated Subsidiaries included in the Able 10-K and the
quarterly reports on Form 10-Q referred to in Section 4.07 fairly present, in
conformity with GAAP (except as may be indicated in the notes thereto), the
consolidated financial position of Able and its consolidated Subsidiaries as of
the dates thereof and their consolidated results of operations and cash flows
for the periods then ended (subject, in the case of any unaudited interim
financial statements, to normal year-end adjustments, none of which,
individually or in the aggregate, would have an Able Material Adverse Effect).

                  SECTION 4.09 Proxy Statement/Prospectus; Registration
Statement. None of the information supplied by Able for inclusion in (a) the
proxy statement relating to the Second Able Stockholder Meeting (also
constituting the prospectus in respect of the Bracknell Common Stock to be
exchanged for Able Shares in the Merger) (the "Proxy Statement/Prospectus"), to
be filed by Able and Bracknell with the SEC, and any amendments or supplements
thereto, or (b) the Registration Statement on Form F-4 (the "Registration
Statement") to be filed by Bracknell with the SEC in connection with the Merger,
and any amendments or supplements thereto, will, at the respective times such
documents are filed, and, in the case of the Proxy Statement/Prospectus, at the
time the Proxy Statement/Prospectus or any amendment or supplement thereto is
first mailed to stockholders of Able, at the time of the Second Able Stockholder
Meeting and at the Effective Time, and, in the case of the Registration
Statement, when it becomes effective under the Securities Act of 1933, contain
any untrue statement of a material fact or omit to state any material fact
necessary in order to make the statements made therein, in the light of the
circumstances under which they were made, not misleading. All documents that
Able is responsible for filing with the SEC in connection with the Merger will
comply as to form in all material respects with the applicable provisions of the
Exchange Act, the Securities Act of 1933 and state securities Laws.

                  SECTION 4.10 Absence of Certain Changes. Except as set forth
on Schedule 4.10 since April 30, 2000, Able and its Subsidiaries have conducted
their business in all material respects in the ordinary course consistent with

                  (a) any event, occurrence or development or state of
         circumstances or facts, which affects or relates to Able or any of its
         Subsidiaries, which has had or would reasonably be expected to have an
         Able Material Adverse Effect;

                  (b)      any declaration, setting aside or payment of any
         dividend or other distribution with respect to any shares of capital
         stock of Able, or any repurchase, redemption or other acquisition by
         Able or any of its Subsidiaries of any outstanding shares of capital
         stock or other securities of, or other ownership interests in, Able or
         any of its Subsidiaries;

                  (c)      any amendment of any term of any outstanding security
         of Able or any of its Subsidiaries;

                  (d)      any incurrence, assumption or guarantee by Able or
         any of its Subsidiaries of any indebtedness for borrowed money other

<PAGE>   27

                  (a)      Liabilities disclosed or provided for in Able's
         consolidated balance sheet dated as of April 30, 2000 included in
         Able's quarterly report on Form 10-Q for the fiscal quarter ended April
         30, 2000;

                  (b)      Liabilities incurred in the ordinary course of
         business consistent with past practices since April 30, 2000, which in

                  (c)      Liabilities under this Agreement.

                  SECTION 4.12 Real Property.

                  (a)      A complete and accurate list and description of all
         real property owned by Able or its Subsidiaries (other than Easements),
         in each case which is used or useful in the conduct of the Business, is
         set forth in Schedule 4.12(a) (the "Owned Real Property"). Able or one
         of its Subsidiaries has good, valid and marketable title in fee simple
         to each Owned Real Property free and clear of all Liens except
         Permitted Liens.

                  (b)      A complete and accurate list and description of all
         the real property leased to Able or its Subsidiaries (other than
         Easements), in each case which is used or useful in the conduct of the
         Business (the "Leased Real Property"), is set forth in Schedule
         4.12(b). Except as set forth on Schedule 4.12(b), all Material Leases
         are in writing and are valid, effective, binding and in full force and
         effect. There has been no material breach of, or default under, any
         Material Lease by Able or one of its Subsidiaries or, to Able's
         Knowledge, any other Person, which breach or default has not been cured
         or waived (and no event has occurred which, with due notice or lapse of
         time or both, may constitute a breach or default), and no party to any
         Material Lease has given Able or one of its Subsidiaries written notice
         or made a claim with respect to any breach or default under a Material
         Lease. A true and complete copy of each of the Material Leases, as
         amended to date, has been furnished to Bracknell. Able or one of its
         Subsidiaries is the lessee or sublessee under all Material Leases or
         has succeeded (or will succeed prior to the Closing Date) to the rights
         of the lessee under such Material Leases and owns the leasehold
         interest created pursuant to such Leases free and clear of all Liens
         except Permitted Liens. Able or one of its Subsidiaries validly
         occupies any improvements located on the Leased Real Property in
         accordance with the terms of the relevant Leases free and clear of all
         Liens except Permitted Liens. All consents required under the Material
         Leases in connection with the transactions contemplated by this
         Agreement have been, or as of the Closing Date will be, obtained and
         furnished in writing to Bracknell.

                  (c)      A complete and accurate list and description of all
         easements, the beneficial interest of which is owned by Able or one of
         its Subsidiaries, in each case which is used or useful in the conduct
         of the Business is listed in Schedule 4.12(c) (the "Easements").
         Schedule 4.12(c) also lists, with respect to each Easement, all
         contracts or other agreements (collectively, the "Easement Contracts")
         pursuant to which Able or one of its Subsidiaries (i) acquired rights
         to the Easement, and/or (ii) granted rights to others to use or access
         any wires, cables, or other conduit located within the respective


                                       26
<PAGE>   28

         Easement areas. Able or one of its Subsidiaries has good, valid, and
         marketable title in and to each Easement free and clear of all Liens
         except Permitted Liens. Each Easement is valid, effective and binding
         and in full force and effect. There has been no material breach of any
         Easement or Easement Contract by Able or its Subsidiaries or, to Able's
         Knowledge, any other Person, which breach has not been cured or waived.
         A true and complete copy of each Easement Contract, as amended to date,
         has been furnished to Bracknell. Able or one of its Subsidiaries
         validly occupies and uses the Easements and any improvements located on
         the Easements in accordance with the terms of the Easement Contracts.
         All consents required under the Easements and Easement Contracts in
         connection with the transactions contemplated by this Agreement have
         been, or as of the Closing Date will be, obtained and furnished in
         writing to Bracknell.

                  (d)      Schedules 4.12(a), 4.12(b) and 4.12(c) describe all
         real property owned or leased by Able or its Subsidiaries (the "Real
         Property"), and the nature of the interest of Able or its Subsidiaries
         in those properties. There is no real property (other than the Real
         Property) the use or possession of which is necessary for Able or its
         Subsidiaries to carry on the Business. Except as provided in Schedule
         4.12(d), none of the Real Property is subject to a Lease, sublease,
         license or other agreement granting any Person any right to the use,
         occupancy or enjoyment thereof (or any portion thereof), except where
         such Lease, sublease, license or other agreement would not materially
         detract from the value of the applicable property, materially impair
         the present and continued use, operation or maintenance of the property
         subject thereto, or materially impair the operations of Able or one of
         its Subsidiaries.

                  (e)      The buildings, driveways and all other structures and
         improvements upon the Real Property are all within the boundary lines
         of the applicable property or have the benefit of valid easements or
         other legal rights and there are no encroachments thereon that would
         materially affect the use thereof.

                  (f)      All buildings, structures, improvements and fixtures
         owned, leased or used by Able or its Subsidiaries in the conduct of the
         Business conform in all material respects to all applicable building,
         zoning, health, safety, environmental and other Laws, regulations,
         codes and rules adopted by national and local associations and boards
         and insurance underwriters, and all such buildings, structures,
         improvements and fixtures and the electrical, plumbing, HVAC and other
         systems thereat are in good operating condition and repair. There are
         no outstanding requirements or recommendations by any insurance company
         which has issued a policy covering any such property, or by any board
         of fire underwriters or other body exercising similar functions,
         requiring or recommending any material repairs or work to be done on
         any such property.

                  (g)      Schedule 4.12(g) lists all policies of title
         insurance insuring the interest of Able and its Subsidiaries in the
         Real Property (the "Title Policies"). All of the Title Policies are in
         full force and effect and neither Able nor any of its Subsidiaries have
         taken or will take any action that would adversely affect the coverage
         afforded the insured thereunder. Able will provide copies of each of
         the Title Policies and any related surveys to Bracknell promptly after
         the date hereof. Able will cooperate with


                                       27
<PAGE>   29

         Bracknell to obtain any new policies or amendments or endorsements to
         the Title Policies as may reasonably be required by Bracknell.

                  SECTION 4.13 Personal Property.

                  (a)      Subject to Permitted Liens, Able or its Subsidiaries
         have marketable and indefeasible title to all personal property owned
         by Able or its Subsidiaries and used in the conduct of the Business,
         other than (A) property that has been disposed of in the ordinary
         course of business, (B) property that has been disposed of in
         transactions disclosed to Bracknell in writing prior to the date
         hereof, and (C) Leased Personal Property.

                  (b)      Schedule 4.13(b) lists all of the Material Leases of
         leased personal property used in the Business conducted by Able and its
         Subsidiaries (the "Leased Personal Property"). All such Material Leases
         of Leased Personal Property are valid and binding and in full force and
         effect. There has been no material breach of any such Material Lease by
         Able or its Subsidiaries or, to Able's knowledge, any other Person,
         which breach has not been cured or waived.

                  SECTION 4.14 Accounts Receivable. Except as set forth on
Schedule 4.14, all Accounts Receivable of Able and its Subsidiaries reflected on
the balance sheet included in Able's Form 10-Q as of April 30, 2000 and all
Accounts Receivable of Able and its Subsidiaries generated after April 30, 2000
that are reflected in the accounting records of Able and its Subsidiaries as of
the Closing Date represent or will represent valid obligations arising from
sales actually made or services actually performed or billed for in the ordinary
course of business. All Accounts Receivable not paid prior to the Closing Date
are current and collectible in the ordinary course of business, except to the
extent reflected in the reserve for doubtful accounts in the financial
statements include in Able's SEC Filings. The reserve for doubtful accounts
reflected in the financial statements included in Able's SEC Filings has been
determined consistent with past practices and in accordance with GAAP. Able and
its Subsidiaries have good and valid title to the Accounts Receivable free and
clear of all Liens except Permitted Liens.

                  SECTION 4.15 Contracts. Except for (i) purchase orders,
invoices, confirmations and similar documents involving the purchase or sale of
goods or services for less than $250,000 over a period of 12 months or less,
(ii) Leases, (iii) Benefit Arrangements, and (iv) contracts relating to
intercompany obligations, Schedule 4.15(i) sets forth a list of all of the
following contracts ("Material Contracts") (A) to which Able or any of its
Subsidiaries is a party or (B) by which any of the assets of Able or any of its
Subsidiaries are bound: (1) contracts pertaining to the borrowing of money; (2)
contracts creating Liens; (3) contracts creating guarantees; (4) contracts
relating to material employment or consulting services; (5) contracts relating
to any single capital expenditure in excess of $250,000 or aggregate capital
expenditures in excess of $500,000; (6) contracts for the purchase or sale of
real property, any business or line of business or for any merger or
consolidation; (7) joint venture or partnership agreements; (8) contracts that
individually require by their respective terms after the date hereof the payment
or receipt of $250,000 or more; (9) any agreement involving derivatives, hedging
or futures under


                                       28
<PAGE>   30

which the obligations of Able or one of its Subsidiaries could reasonably be
expected to exceed $250,000; (10) any contract that limits the freedom of Able
or its Subsidiaries to compete in any line of business or to conduct business in
any geographic location; or (11) any contract for the purchase or sale of all or
substantially all of the assets or stock of any company or operating division.
All Material Contracts are valid and binding and in full force and effect.
Except as disclosed in Schedule 4.15(ii), there has been no material breach of
any contract by Able or its Subsidiaries or, to Able's Knowledge, any other
Person, which breach has not been cured or waived. Able will make available to
Bracknell true and complete copies of the Material Contracts.

                  SECTION 4.16 Litigation. Except as set forth on Schedule 4.16,
there is no Action by any Person or by or before any Governmental Authority that
is pending or, to Able's Knowledge, threatened by, against or affecting Able or
its Subsidiaries or any of their respective assets which would have or
reasonably be expected to have an Able Material Adverse Effect. Except as set
forth on Schedule 4.16, neither Able nor any of its Subsidiaries is subject to
any Order that would have an Able Material Adverse Effect.

                  SECTION 4.17 Taxes. Except as set forth on Schedule 4.17(i),
Able and its Subsidiaries have timely filed all Returns and reports required to
be filed by them on or before the date hereof, or requests for extensions to
file such Returns have been timely filed and granted and have not yet expired.
All such Returns are complete and accurate. Able and its Subsidiaries have paid,
or have set up an adequate reserve for the payment of, all Taxes due, whether or
not shown as due, on such Returns and have properly withheld and paid over to
the appropriate Governmental Authority all applicable withholding Taxes. The
interim balance sheet contained in Able's Form 10-Q for its fiscal quarter ended
April 30, 2000 contains an adequate reserve for all Taxes accrued by Able and
its Subsidiaries through April 30, 2000. Except as set forth on Schedule
4.17(ii), no deficiencies for any Taxes have been asserted, proposed or
otherwise settled or reserved against, Able has not received any notice of and
has no reason to believe that any deficiency for any Taxes will be proposed or
threatened, and no waivers of the time to assess any such Taxes are pending.
There are no material Liens for Taxes (other than Permitted Liens for current
Taxes not yet due and payable) on the assets of Able or any of its Subsidiaries.
No election under Section 341(f) of the Code has been or will be made to treat
Able or any of its Subsidiaries as a "consenting corporation" as defined in such
Section 341(f). Neither Able nor any of its Subsidiaries is a party to any
agreement, contract or arrangement that has resulted or could result in any
disallowance of a deduction for employee remuneration under Section 162(m) of
the Code or that would result, separately or in the aggregate, in any payment
(whether or not in connection with any termination of employment or otherwise)
of any "excess parachute payment" within the meaning of Section 280G of the
Code. Except as set forth on Schedule 4.17(iii), neither Able nor any of its
Subsidiaries has been a party to any deferred intercompany transaction pursuant
to which it realized but did not recognize a gain, and no excess loss account
exists with respect to the shares of stock of any member of the federal
consolidated income tax group of which Able is the common parent. Neither Able
nor any of its Subsidiaries is or has been a party to any Tax sharing agreement
or has or could have any liability for Taxes pursuant to Section 1.1502-6 of the
regulations promulgated pursuant to the Code for the Taxes of any Person other
than a corporation that is currently a member of the federal consolidated income
Tax group of which Able is the common parent. Able has no reason to believe that
any of its net


                                       29
<PAGE>   31

operating loss carryforwards, foreign Tax credit carryforwards or other similar
Tax attributes would be reduced or disallowed by any taxing authority if its
Returns for the years in which such Tax attributes were created were audited.
Except as set forth on Schedule 4.17(iv), no audit of Able or any of its
Subsidiaries by any taxing authority is currently pending or threatened, and no
issues have been raised by any taxing authority in connection with any Returns
of Able or any of its Subsidiaries.

                  SECTION 4.18 Tax Free Merger.

                  (a)      Following the Merger, the Surviving Corporation will
         hold at least 90 percent of the fair market value of the net assets,
         and at least 70 percent of the fair market value of the gross assets,
         held by Able prior to the Merger. For purposes of this representation,
         amounts used by Able to pay reorganization expenses and all
         redemptions, distributions and payments, in cash or property, made by
         Able in connection with the Merger shall be included as assets of Able
         prior to the Merger.

                  (b)      Able has no plan or intention to issue additional
         shares of it stock that would result in Bracknell losing control of
         Able within the meaning of Section 368(c) of the Code. At the time of
         the Merger, Able will not have outstanding any warrants, options,
         convertible securities, or any other type of right pursuant to which
         any Person could acquire stock in Able that, if exercised or converted,
         would affect Bracknell's acquisition or retention of such control.

                  (c)      There is no intercorporate indebtedness existing
         between Bracknell and Able or between Subco and Able. Able is not an
         investment company as defined in Section 368(a)(2)(F)(iii) and (iv) of
         the Code. On the date of the Merger, the fair market value of the
         assets of Able will exceed the sum of its liabilities plus the
         liabilities, if any, to which its assets are subject. Able is not under
         the jurisdiction of a court in a Title 11 or similar case within the
         meaning of Section 368(a)(3)(A) of the Code.

                  (d)      Able agrees to treat the Merger as a reorganization
         within the meaning of Section 368(a) of the Code. This Agreement is
         intended to constitute a "plan of reorganization" within the meaning of
         Section 1.368-2(g) of the income Tax regulations promulgated under the
         Code. Able has not knowingly taken any action that would jeopardize the
         qualification of the Merger as a reorganization within the meaning of
         Section 368(a) of the Code. During the period from the date of this
         Agreement through the Effective Time, unless all parties hereto shall
         otherwise agree in writing, Able shall not knowingly take or fail to
         take any action which action or failure would jeopardize the
         qualification of the Merger as a reorganization within the meaning of
         Section 368(a) of the Code. Able shall cause one or more of its
         responsible officers to execute and deliver certificates to confirm the
         accuracy of certain relevant facts as may be reasonably requested by
         counsel in connection with the preparation and delivery of the Tax
         opinion described in Section 9.01(f).

                  SECTION 4.19 ERISA.

                  (a)      "Employee Plans" shall mean each "employee benefit
         plan", as defined in Section 3(3) of the Employee Retirement Income
         Security Act of 1974 ("ERISA"), which (i) is subject to any provision
         of ERISA and (ii) is maintained, administered or contributed to by Able
         or any affiliate (as defined below) and covers any employee or former
         employee of Able or any affiliate or under which Able or any affiliate
         has any liability. Schedule 4.19(a) lists all Employee Plans. True and
         complete copies of such plans (and, if applicable, related trust
         agreements) and all amendments thereto have been furnished to
         Bracknell. For purposes of this Section, "affiliate" of any Person
         means any other Person which, together with such Person, would be
         treated as a single employer under Section 414 of the Code.

                  (b)      No Employee Plan individually or collectively
         constitutes a "defined benefit plan" as defined in Section 3(35) of
         ERISA.

                  (c)      No Employee Plan constitutes a "multi-employer plan",
         as defined in Section 3(37) of ERISA, and no Employee Plan is
         maintained in connection with any trust described in Section 501(c)(9)
         of the Code. No Employee Plan is subject to Title IV of ERISA. Neither
         Able nor any of its affiliates has incurred, nor has reason to expect
         to incur, any liability under Title IV of ERISA arising in connection
         with the termination of, or complete or partial withdrawal from, any
         plan previously covered by Title IV of ERISA.

                  (d)      Nothing done or omitted to be done and no transaction
         or holding of any asset under or in connection with any Employee Plan
         has or will make Able or any of its Subsidiaries or any officer or
         director of Able or any of its Subsidiaries subject to any liability
         under Title I of ERISA or liable for any Tax pursuant to Section 4975
         of the Code that would have, or reasonably be expected to have,
         individually or in the aggregate, an Able Material Adverse Effect.

                  (e)      Each Employee Plan which is intended to be qualified
         under Section 401(a) of the Code is so qualified and has been so
         qualified during the period from its adoption to date, and each trust
         forming a part thereof is exempt from Tax pursuant to Section 501(a) of
         the Code, and each Employee Plan has been maintained in material
         compliance with its terms and with the requirements prescribed by any
         and all statutes, Orders, final rules and final regulations, including
         but not limited to ERISA and the Code, which are applicable to such
         Employee Plan.

                  (f) There is no contract, agreement, plan or arrangement
         covering any employee or former employee of Able or any affiliate that,
         individually or collectively, could give rise to the payment of any
         amount that would not be deductible pursuant to the terms of Section
         280G of the Code.

                  (g)      "Benefit Arrangement" shall mean each employment,
         severance or other similar contract, arrangement or policy and each
         plan or arrangement (written or oral)


                                       31
<PAGE>   33

         providing for compensation, bonus, profit-sharing, or other forms of
         incentive or deferred compensation, vacation benefits, insurance
         coverage (including any self-insured arrangements), health or medical
         benefits, disability benefits, workers' compensation with the exception
         of the stock options disclosed in Schedule 4.05(a)(i) or Schedule
         4.05(a)(ii), supplemental unemployment benefits, severance benefits and
         post-employment or retirement benefits (including compensation, health
         or medical insurance or other benefits) which (i) is not an Employee
         Plan, (ii) is entered into, maintained or contributed to, as the case
         may be, by Able or any of its affiliates, and (iii) covers any employee
         or former employee of Able or any of its affiliates. Copies or
         descriptions of the Benefit Arrangements have been furnished to
         Bracknell. Each Benefit Arrangement has been maintained in compliance
         with its terms and with the requirements prescribed by any and all Laws
         that are applicable to such Benefit Arrangement.

                  (h)      Except as disclosed in Schedule 4.19(h), the
         transactions contemplated hereby will not result in any liability for
         severance pay to any employee or accelerate the exercisability, vesting
         or payment of any options, warrants, stock appreciation rights, phantom
         stock awards or any similar instruments, as the case may be, nor will
         any employee be entitled to any payment solely by reason of such
         transactions.

                  (i)      All contributions required to be made to trusts in
         connection with any Employee Plan that would constitute a "defined
         contribution plan" (within the meaning of Section 3(34) of ERISA) have
         been made in a timely manner in compliance with applicable law and
         regulations;

                  (j)      Other than claims in the ordinary course for benefits
         with respect to the Employee Plans or Benefit Arrangements, there are
         no Actions, suits or claims (including claims for income Taxes,
         interest, penalties, fines or excise Taxes with respect thereto)
         pending with respect to any Employee Plan or Benefit Arrangement, or
         any circumstances which might give rise to any such Action, suit or
         claim (including claims for income Taxes, interest, penalties, fines or
         excise Taxes with respect thereto);

                  (k)      All reports, returns and similar documents with
         respect to the Employee Plans or Benefit Arrangements required to be
         filed with any governmental agency have been so filed by the due date
         for such filings;

                  (l)      Able has no obligation to provide health or other
         welfare benefits to former, retired or terminated employees, except as
         specifically required under Section 4980B of the Code or Section 601 of
         ERISA. Able has complied with the notice and continuation requirements
         of Section 4980B of the Code and Section 601 of ERISA and the
         regulations thereunder.

                   (m)     Except as disclosed in writing to Bracknell prior to
         the date hereof and subject to the provisions of Section 4.10(l), there
         has been no amendment to, written interpretation or announcement
         (whether or not written) by Able or any of its affiliates relating to,
         or change in employee participation or coverage under, any Employee
         Plan or Benefit Arrangement which in the aggregate would increase the
         per employee expense of


                                       32
<PAGE>   34

         of the expense incurred on a per employee basis in respect thereof for
         the six months ended on April 30, 2000 except to the extent, with
         respect to all employees, as would not have, or reasonably be expected
         to have, individually or in the aggregate, an Able Material Adverse
         Effect.

                  SECTION 4.20 Environmental Matters. Except as set forth in

Subsidiaries; (f) no Site or any property to which Able or any of its
Subsidiaries has, directly or indirectly, transported or arranged for the
transportation of any Hazardous Material, is a current or proposed Environmental
Cleanup Site; (g) there are no Liens arising under or pursuant to any
Environmental Law on any Site and there are no facts, circumstances or

                  SECTION 4.28 Compliance With Other Applicable Laws. Able and
its Subsidiaries have in effect all Permits necessary for them to own, lease or
operate the properties and assets of Able and its Subsidiaries and to carry on
the Business as now conducted, and there has not occurred any default under any
Permit, except for the absence of Permits and for defaults under Permits that
have not had an Able Material Adverse Effect. Able and its Subsidiaries are in
compliance with all Other Applicable Law, except where failure to so comply

maintains insurance with responsible and reputable insurers in such amounts and
covering such risks and with such deductibles as are generally maintained by
like businesses, the failure of which to maintain would or would have reasonably
be expected to have an Able Material Adverse Effect. The coverage under each
such policy is in full force and effect and Able and each of its Subsidiaries is
in good standing under such policies, unless the lack of such coverage or good
standing would not have or would not reasonably be expected to have an Able
Material Adverse Effect. Neither Able nor any of its Subsidiaries has received
notice of, or has any knowledge of, any fact, condition or circumstance which
might reasonably form the basis of any claim against Able or any of its
Subsidiaries which is not fully covered by insurance (subject to deductibles)

reasonably be expected to have an Able Material Adverse Effect.

of Florida, and (iii) the filing with, and approval by, the TSE of the
conditional listing application and satisfaction of the conditions contained

         of the assets of Bracknell or any of its Subsidiaries, other than
         assets sold, leased or otherwise disposed of in the ordinary course of
         business consistent with past practice and which would not, in the
         aggregate, have a Bracknell Material Adverse Effect;

                  (e)      any material purchase or lease of any assets by
         Bracknell or any of its Subsidiaries, other than assets purchased or
         leased in the ordinary course of business consistent with past practice
         which would not, in the aggregate, have a Bracknell Material Adverse
         Effect;

                  (f)      any material increase in the compensation payable to
         any of the employees of Bracknell or any of its Subsidiaries, except

         Material Adverse Effect; or

                  (g)      any agreement or commitment by Bracknell or any of
         its Subsidiaries to take any action described in this Section 5.09.

                  SECTION 5.10 Litigation. Except as set forth on Schedule 5.10
there is no Action by any Person or by or before any Governmental Authority that
is pending or, to Bracknell's Knowledge, threatened by, against or affecting
Bracknell or its Subsidiaries or any of their respective assets that would have
a Bracknell Material Adverse Effect. Except as set



                                       40
<PAGE>   42

forth on Schedule 5.10, neither Bracknell nor any of its Subsidiaries is subject
to any Order that would have a Bracknell Material Adverse Effect.

                  SECTION 5.11 Taxes. Except as set forth on Schedule 5.11(i),
Bracknell and its Subsidiaries have timely filed all Returns required to be
filed by them on or before the date hereof, except where failure to timely file
would not have a Bracknell Material Adverse Effect. All such Returns are
complete and accurate except where the failure to be complete or accurate would
not have a Bracknell Material Adverse Effect. Bracknell and its Subsidiaries
have paid, or have set up an adequate reserve for the payment of, all Taxes
shown as due on such Returns, except where the failure to do so would not have a
Bracknell Material Adverse Effect. Bracknell's Second Quarter Interim Report for

accrued by Bracknell and its Subsidiaries through April 30, 2000. Except as set
forth on Schedule 5.11(ii), no deficiencies for any Taxes have been asserted,
proposed or assessed against Bracknell or its Subsidiaries in writing that have
not been paid or otherwise settled or reserved against, except for deficiencies
the assertion, proposing or assessment of which would not have a Bracknell
Material Adverse Effect, and no waivers of the time to assess any such Taxes are
pending (other than for current Taxes not yet due and payable) on the assets of
Bracknell or any of its Subsidiaries.

                  SECTION 5.12 Tax Free Merger.

                  (a)      Following the Merger, and as a result thereof, the
         Surviving Corporation will hold at least 90 percent of the fair market
         value of the net assets and at least 70 percent of the fair market
         value of the gross assets held by Subco prior to the Merger (excluding
         the Merger Consideration).

                  (b)      Bracknell will acquire Able stock solely in exchange
         for Bracknell voting stock, and in the Merger, shares of Able stock
         representing control of Able, as defined in Section 368(c) of the Code,
         will be exchanged solely for voting stock of Bracknell.

                  (c)      Subco will have no liabilities assumed by the
         Surviving Corporation, and will not transfer to the Surviving
         Corporation in the Merger any assets subject to liabilities.

                  (d)      There is no intercorporate indebtedness existing
         between Bracknell and Able or between Subco and Able. Bracknell does
         not own, directly or indirectly, nor has it owned during the past five
         years, directly or indirectly, any stock of Able.

                  (e)      Neither Bracknell nor Subco is an investment company
         as defined in Section 368(a)(2)(F)(iii) and (iv) of the Code.

                  (f)      Prior to the Merger, Bracknell will be in control of
         Subco within the meaning of Section 368(c) of the Code.

                  (g)      Bracknell has no plan or intention as part of the
         plan of the Merger to cause the Surviving Corporation to issue after
         the Effective Time additional shares of stock that would result in
         Bracknell losing control of the Surviving Corporation within


                                       41
<PAGE>   43

         the meaning of Section 368(c) of the Code, or any warrants, options,
         convertible securities, or any other type of right pursuant to which
         any person could acquire stock in the Surviving Corporation that, if
         exercised or converted, would affect Bracknell's acquisition or
         retention of control of the Surviving Corporation, as defined in
         Section 368(c) of the Code.

                  (h)      Bracknell has no plan or intention to reacquire any
         of the Bracknell Common Stock issued in the Merger.

                  (i)      Bracknell has no plan or intention to liquidate the
         Surviving Corporation, to merge the Surviving Corporation with or into
         another corporation or to sell or otherwise dispose of the Surviving
         Corporation stock except for transfers of stock to a corporation
         controlled by Bracknell.

                  (j)      Bracknell will cause the Surviving Corporation to
         attach to a timely filed U.S. income Tax Return for the taxable year in
         which the Merger occurs the statement required by Section
         1.367(a)-3(c)(6) of the Treasury regulations issued under Section
         367(a) of the Code.

                  (k)      Following the Merger, the Surviving Corporation will
         continue Able's historic business or use a significant portion of its
         historic business assets in a business.

                  (l)      Bracknell agrees to treat the Merger as a
         reorganization within the meaning of Section 368(a) of the Code. This
         Agreement is intended to constitute a "plan of reorganization" within
         the meaning of Section 1.368-2(g) of the income Tax regulations
         promulgated under the Code. Neither Bracknell nor Subco has knowingly
         taken any action that would jeopardize the qualification of the Merger
         as a reorganization within the meaning of Section 368(a) of the Code.
         During the period from the date of this Agreement through the Effective
         Time, unless all parties hereto shall otherwise agree in writing,
         neither Bracknell nor Subco shall knowingly take or fail to take any
         action which action or failure would jeopardize the qualification of
         the Merger as a reorganization within the meaning of Section 368(a) of
         the Code. Bracknell shall cause one or more of its responsible officers
         to execute and deliver certificates to confirm the accuracy of certain
         relevant facts as may be reasonably requested by counsel in connection
         with the preparation and delivery of the tax opinion described in
         Section 9.01(f).

                  (m)      Following the Effective Time, Bracknell shall use its
         commercially reasonable best efforts, and shall cause the Surviving
         Corporation to use its commercially reasonable best efforts, to conduct
         its business and the Surviving Corporation's business in a manner which
         would not jeopardize the characterization of the Merger as a
         reorganization within the meaning of Section 368(a) of the Code.

                  SECTION 5.13 Compliance With Other Applicable Laws. Bracknell
and its Subsidiaries have in effect all Permits necessary for them to own, lease
or operate the properties and assets of Bracknell and its Subsidiaries and to
carry on the Business as now conducted, and


                                       42
<PAGE>   44

there has not occurred any default under any Permit, except for the absence of
Permits and for defaults under Permits that have not had a Bracknell Material
Adverse Effect. Bracknell and its Subsidiaries are in compliance with all Other
Applicable Law, except where failure to so comply would not have a Bracknell
Material Adverse Effect. Except as set forth in Schedule 5.13, no investigation
or review by any Governmental Authority with respect to Bracknell or any of its
Subsidiaries is pending, or to Bracknell's Knowledge, threatened.

                  SECTION 5.14 Brokers. Except as disclosed in Schedule 5.14, no
Person is or will become entitled to receive any brokerage or finder's fee,
advisory fee or other similar payment for the transactions contemplated by this
Agreement by virtue of having been engaged by or acted on behalf of Bracknell or
any of its Subsidiaries.

                  SECTION 5.15 Certain Payments. Excluding any matters that have
been resolved, to Bracknell's Knowledge, neither Bracknell, nor any of its
Subsidiaries, directors, officers, agents, employees, or any other Person
associated with or acting for or on behalf of Bracknell or any of its
Subsidiaries, has directly or indirectly (i) made any contribution, gift, bribe,
rebate, payoff, influence payment, kickback, or other payment to any Person,
private or public, regardless of form, whether in money, property, or services
(A) to obtain favorable treatment in securing business, (B) to pay for favorable
treatment in securing business, or (C) to obtain special concessions or for
special concessions already obtained, for or in respect of Bracknell or any of
its Subsidiaries, or (ii) established or maintained any fund or asset that has
not been appropriately recorded in the books or records of Bracknell or its
Subsidiaries, which in the case of either clause (i) or (ii) would be in
violation of Law.

                  SECTION 5.16 Interim Operations of Subco. Subco was formed
solely for the purpose of engaging in the transactions contemplated hereby, has
engaged in no other business activities and has conducted its operations only as
contemplated hereby.

                  SECTION 5.17 Authorization for Bracknell Common Stock. Prior
to the Closing Date, Bracknell will have taken all necessary action to permit it
to issue the number of shares of Bracknell Common Stock to be issued pursuant to
the terms of this Agreement. Shares of Bracknell Common Stock issued pursuant to
the terms of this Agreement will, when issued, be validly issued, fully paid and
nonassessable and no person will have any preemptive right of subscription or
purchase in respect thereof. Such shares of Bracknell Common Stock will be
conditionally listed on the TSE.

                  SECTION 6.02 Stockholder Meetings.

                  (a)      Able shall cause a meeting of its stockholders to be
         duly called and held as soon as reasonably practicable, but in no event
         later than October 31, 2000 (the "First Able Stockholder Meeting"), for

         Able will, subject to the foregoing and Section 6.04, use its
         commercially reasonable best efforts to obtain the necessary approvals
         by its stockholders of this Agreement, the transactions contemplated
         hereby and such other matters as are contemplated by the terms of this
         Agreement or required by the Florida General Corporation Law, and will
         otherwise comply with all legal requirements applicable to such
         meetings.

                  SECTION 6.03 Access to Information. From the date hereof until
the Effective Time, Able will give Bracknell, its counsel, financial advisors,

to the offices, properties, books and records of Able and its Subsidiaries, will
furnish to Bracknell, its counsel, financial advisors, environmental
consultants, auditors and other authorized representatives such financial and
operating data and other information as such Persons may reasonably request and
will instruct Able's employees, counsel and financial advisors to cooperate with
Bracknell in its investigation of the business of Able and its Subsidiaries;
provided that no investigation pursuant to this Section shall affect any
representation or warranty given by Able to Bracknell hereunder; and further
provided that, such access is at normal business hours and does not materially
interfere with the conduct of Able's Business.

                  SECTION 6.04 Other Offers.

                  (a)      Able will not, nor will it permit any of its
         Subsidiaries to, nor will it authorize or permit any officer, director
         or employee of, or any investment banker, attorney, accountant or other
         advisor or representative of, Able or any of its Subsidiaries to,
         directly or indirectly, (i) solicit, initiate or encourage the
         submission of any


                                       45
<PAGE>   47

         Acquisition Proposal (as defined below) or (ii) participate in any
         discussions or negotiations regarding, or furnish to any person any
         information in respect of, or take any other action to facilitate, any
         Acquisition Proposal or any inquiries or the making of any proposal
         that constitutes, or may reasonably be expected to lead to, any
         Acquisition Proposal; provided, however, that nothing contained in this
         Section 6.04(a) shall prohibit the Able Board of Directors from
         furnishing any information to, or entering into discussions or
         negotiations with, any person that makes an unsolicited bona fide
         Acquisition Proposal if, and only to the extent that (A) the Second
         Able Stockholder Meeting shall not have occurred, (B) the Able Board of
         Directors, after consultation with outside legal counsel, determines in
         good faith that the failure to take such action would be inconsistent
         with its fiduciary duties to Able's stockholders under applicable Law,
         as such duties would exist in the absence of any limitation in this
         Agreement, (C) the Able Board of Directors determines in good faith
         that such Acquisition Proposal is reasonably likely to lead to a
         transaction that, if accepted, is reasonably likely to be consummated
         taking into account all legal, financial, regulatory and other aspects
         of the proposal and the person making the proposal, and believes in
         good faith, after consultation with its financial advisor and after
         taking into account the strategic benefits to be derived from the
         Merger and the long-term prospects of Bracknell and its Subsidiaries,
         based on the information available to the Able Board of Directors at
         the time, that such Acquisition Proposal would, if consummated, result
         in a transaction more favorable to Able's stockholders than the Merger
         (any such more favorable Acquisition Proposal being referred to herein
         as a "Superior Proposal"), and (D) prior to taking such action, Able
         (x) provides reasonable notice to Bracknell to the effect that it is
         taking such action and (y) receives from the Person submitting such
         Acquisition Proposal an executed confidentiality/standstill agreement
         in reasonably customary form and in any event containing terms at least
         as stringent as those contained in the Term Sheet between Bracknell and
         WorldCom and Able. "Acquisition Proposal" means an inquiry, offer or
         proposal regarding any of the following (other than the transactions
         contemplated by this Agreement) involving Able or any of its
         Subsidiaries: (w) any merger, consolidation, share exchange,
         recapitalization, business combination or other similar transactions;
         (x) any sale, lease, exchange, mortgage, pledge, transfer or other
         disposition of all or substantially all the assets of Able and its
         Subsidiaries, taken as a whole, in a single transaction or series of
         related transactions; (y) any tender offer or exchange offer for 20% or
         more of the outstanding Able Shares or the filing of a registration
         statement under the Securities Act of 1933 in connection therewith; or
         (z) any public announcement of a proposal, plan or intention to do any
         of the foregoing or any agreement to engage in any of the foregoing.

                  (b)      Able shall notify Bracknell of any Acquisition
         Proposal (including, the material terms and conditions thereof and the
         identity of the Person making it) as promptly as practicable (but in no
         case later than 24 hours) after its receipt thereof, and shall
         thereafter inform Bracknell on a prompt basis of the status of any
         discussions or negotiations with such third party, and any material
         changes to the terms and conditions of such Acquisition Proposal, and
         shall promptly give Bracknell a copy of any information delivered to
         such Person which has not previously been reviewed by Bracknell.

                  (c)      Able has ceased and terminated, and has caused its
         Subsidiaries and Affiliates, and their respective officers, directors,
         employees, investment bankers, attorneys, accountants and other agents
         and representatives to cease and terminate, any existing activities,
         discussions or negotiations with any parties conducted heretofore in
         respect of any possible Acquisition Proposal. Able shall take all
         necessary steps to promptly inform the individuals or entities referred
         to in the first sentence of Section 6.04(a) of the obligations
         undertaken in this Section 6.04.

                  (d)      The Able Board of Directors will not withdraw or
         modify, or propose to withdraw or modify, in a manner adverse to
         Bracknell, its approval or recommendation of the Merger unless the Able
         Board of Directors, after consultation with outside legal counsel,
         determines in good faith that the failure to take such action would be
         inconsistent with its fiduciary duties to Able's stockholders under
         applicable Law; provided, however, that the Able Board of Directors may
         not approve or recommend an Acquisition Proposal (and in connection
         therewith, withdraw or modify its approval or recommendation of the
         Merger) unless such an Acquisition Proposal is a Superior Proposal (and
         Able shall have first complied with its obligations set forth in
         Section 10.02 and the time referred to in the last sentence of Section
         10.02 has expired) and unless it shall have first consulted with
         outside legal counsel, and have determined that the failure to take
         such action would be inconsistent with its fiduciary duties to Able's
         stockholders.

                  (e)      Nothing contained in this Section 6.04 shall prohibit
         Able from taking and disclosing to its stockholders a position
         contemplated by Rule 14d-9 or Rule 14e-2(a) promulgated under the
         Exchange Act or from making any disclosure to Able's stockholders
         which, in the good faith reasonable judgment of the Able Board of
         Directors, after consultation with outside legal counsel, is required
         under applicable Law; provided, however, that except as otherwise
         permitted in this Section 6.04, Able does not withdraw or modify, or
         propose to withdraw or modify, its position in respect of the Merger or
         approve or recommend, or propose to approve or recommend, an
         Acquisition Proposal.

                  (f)      Notwithstanding anything contained in this Agreement
         to the contrary, any action by the Able Board of Directors permitted
         by, and taken in accordance with, this Section 6.04 shall not
         constitute a breach of this Agreement by Able. Nothing in this Section
         6.04 shall (i) permit Able to terminate this Agreement (except as
         provided in Article X hereof) or (ii) affect any other obligations of
         Able under this Agreement.

                  SECTION 6.05 Notice of Certain Events. Able shall promptly
         notify Bracknell in writing of:

                           (i)      any notice or other communication from any
                  Person alleging that the consent of such Person (or another
                  Person) is or may be required in connection with the
                  transactions contemplated by this Agreement;

                  connection with the transactions contemplated by this
                  Agreement; and

                           (iii)    any Actions, suits, claims, investigations
                  or proceedings commenced or, to Able's Knowledge threatened
                  against, relating to or involving or otherwise affecting Able
                  or any of its Subsidiaries which, if pending on the date of
                  this Agreement, would have been required to have been
                  disclosed pursuant to Section 4.16 or Section 6.20 or which

mailed to its stockholders, and if necessary, after the definitive Proxy
Statement/Prospectus shall have been mailed, promptly circulate amended,
supplemented or supplemental proxy materials and, if required in connection

                                    Bracknell to Able; provided that Able shall

                                    30 days after written notice of such breach

                                    judgement of Bracknell, would constitute an
                                    Able Material Adverse Change, or (y) any
                                    change of Law on or before the date of such
                                    termination shall have occurred which, in

                                   industry of Bracknell generally and also
                                   affects Able.

                  SECTION 10.02 Termination by Able. This Agreement may be
terminated and the Merger may be abandoned at any time prior to the Closing by
action of the Able Board of Directors in writing, if (i) Able is not in breach
of Section 6.04, (ii) the Merger shall not have been approved by the Able
stockholders, (iii) the Able Board of Directors authorizes Able, subject to
complying with the terms of this Agreement, to enter into a binding written
agreement concerning a transaction that constitutes a Superior Proposal and Able
promptly notifies Bracknell in writing that it intends to enter into such an
agreement, attaching the most current version of such agreement to such notice,
and (iv) during the three business day period after Able's notice, (A) Able
shall have negotiated with, and shall have caused its respective financial and
legal advisors to negotiate with, Bracknell to attempt to make such commercially
reasonable adjustments in the terms and conditions of this Agreement as would
enable Able to proceed with the transactions contemplated hereby, and (B) the
Able Board of Directors shall have concluded, after considering the results of
such negotiations, that any Superior Proposal giving rise to Able's notice
continues to be a Superior Proposal. Able may not effect such termination unless
contemporaneously therewith Able pays to Bracknell in immediately available
funds the fees required to be paid pursuant to Section 10.04. Able agrees (x)
that it will not enter into a binding agreement referred to in clause (iii)
above until at least the day following the third business day after it has
provided the notice to Bracknell required thereby, and (y) to notify Bracknell
promptly if its intention to enter into a written agreement referred to in its
notification shall change at any time after giving such notification.

                  SECTION 10.03 Termination by Bracknell. This Agreement may be
terminated and the Merger may be abandoned at any time prior to the Closing by
Bracknell in writing, if either (i) Able enters into a binding agreement for a
Superior Proposal, or (ii) the Able Board of Directors shall have withdrawn or
adversely modified its approval or recommendation of the Merger.

                  SECTION 10.04 Effect of Termination.

                  (a)      If this Agreement is terminated pursuant to Sections
         10.01, 10.02, or 10.03, this Agreement shall become void and of no
         effect with no liability on the part of any party hereto, except that
         (i) the agreements contained in Section 11.04 and Section 10.04 shall
         survive the termination hereof, and (ii) the parties shall be liable
         for any willful breaches hereof.

                  (b)      In the event that (i) a bona fide Acquisition
         Proposal shall have been made or any person shall have publicly
         announced an intention (whether or not conditional) to make a bona fide
         Acquisition Proposal in respect of Able or any of its Subsidiaries and
         thereafter this Agreement is terminated by either Bracknell or Able
         pursuant to Section 10.01(d) or by Bracknell pursuant to Section
         10.01(e) as a result of a material breach by Able of any of the
         covenants set forth in Section 6.04 hereof, or (ii) this Agreement is
         terminated by Able pursuant to Section 10.02, or (iii) this Agreement
         is terminated by Bracknell pursuant to Section 10.03, then on the date
         of such termination Able shall pay Bracknell a termination fee of
         $3,000,000 as liquidated damages in immediately available funds and the
         Bracknell Option shall become exercisable according to its terms.

                  (c)      In the event that this Agreement is terminated by
         Bracknell or Able pursuant to Section 10.01(d) or by Bracknell pursuant
         to Section 10.01(e) (other than as described in clause 10.04(b)(i) and
         other than as a result of a breach of Section 6.08 by Able), then Able
         shall pay Bracknell a termination fee of $3,000,000 as liquidated
         damages in immediately available funds on the date of such termination.

                  (d)      Able acknowledges that the agreements contained in
         Sections 10.04(b) and (c) are an integral part of the transactions
         contemplated by this Agreement, and that, without these agreements,
         Bracknell and Subco would not have entered into this Agreement;
         accordingly, if Able fails to promptly pay the amount due pursuant to
         Section 10.04(b) or (c), and, in order to obtain such payment,
         Bracknell commences a suit which results in a judgment against Able for
         the fee set forth in Section 10.04(b) or (c), Able shall pay to
         Bracknell its costs and expenses (including attorneys' fees) in
         connection with such suit, together with interest from the date of
         termination of this Agreement on the amounts owed at the rate of 8.5%
         per annum.
