may acquire upon exchange of such Canadian Buyer Shares will not be registered
under the Act at Closing and may not be sold or otherwise disposed of in the
United States or to a U.S. Person (as defined in Regulation S under the Act)
unless they are so registered or are sold or otherwise disposed of in a
transaction that is exempt from such registration, and (ii) the certificates
representing such Canadian Buyer Shares and such shares of Common Stock will
bear legends for so long as such shares are restricted securities under the Act,
in addition to the legends required by Canadian law, identical with or similar
to the following:

                  "THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE UNITED
STATES SECURITIES ACT OF 1933 OR THE SECURITIES LAWS OF ANY STATE OF THE UNITED
STATES. THEY MAY NOT BE SOLD OR OTHERWISE TRANSFERRED IN THE UNITED STATES OR TO
A U.S. PERSON (AS DEFINED IN REGULATION S OF THE SEC UNDER SUCH ACT) IN THE
ABSENCE OF REGISTRATION (OR IN COMPLIANCE WITH AN EXEMPTION FROM SUCH
REGISTRATION) UNDER SUCH ACT AND SUCH APPLICABLE STATE SECURITIES LAWS."


                  (b) Each Seller acknowledges that he or she has received and
read carefully (x) TKOG's Registration Statement on Form S-1 as filed with the
SEC on March 17, 1998 and any amendments and supplements thereto ("Registration

31, 1997 ("Form 10-K"), and (z) TKOG's Quarterly Report on Form 10-Q for the

                  (c) Each Seller has evaluated the merits and risks of an
investment in the Canadian Buyer Shares to be issued at the Closing hereunder
and the shares of Common Stock for which they are exchangeable, and has
affirmatively decided to make such investment based solely on such evaluation,
the representations, warranties and covenants of TKOG and the Buyers contained
in this Agreement (or in any schedule, certificate or other document delivered
by TKOG or the Buyers pursuant hereto) and the information contained (or
incorporated by reference) in the documents referred to in Section 4.26(b).

                  (d) None of the Sellers is affiliated, directly or indirectly,
with a member broker-dealer firm of the National Association of Securities

or otherwise dispose of any of such securities, or any interest therein, in

plan or intention to sell, exchange or otherwise dispose of any of such
securities, or any interest therein, in violation of such registration
requirements.

              (f) Each Seller is either (i) an accredited investor as that term
is defined in Rule 501 promulgated under the Act, or (ii) has, either alone or
with his purchaser representative or representatives (as that term is defined in
Rule 501 promulgated under the Act), such knowledge and experience in financial
and business matters that he is capable of evaluating the merits and risks of an
investment in the Common Stock. By reason of each Seller's business or financial
experience, he or she is a sophisticated investor who has the capacity to
protect his or her interest in connection with the transactions contemplated
hereunder and has both appropriate knowledge and experience with the current
business operations and prospects of TKOG and in financial and business matters
to evaluate properly the merits and risks of the Common Stock and the related
transactions contemplated hereunder.

              (g) Seller has read this Agreement and all other documents
provided by TKOG in connection herewith and fully understands the terms under
which the Common Stock is being issued to him or her. TKOG and the Buyers have
made available to each Seller the opportunity to ask questions of and receive
answers from TKOG or the Buyers concerning TKOG and the terms and conditions
under which Common Stock will be issued to him or her and to obtain any
additional information which TKOG or the Buyers possess or can acquire without
unreasonable effort or expense that is necessary to verify the accuracy of
information furnished in connection with this Agreement or in response to any
request for information. Each Seller is satisfied with such answers and
information.

                           Notes shall be automatically adjusted to
                           appropriately reflect any such adjustment to the
                           liability for deferred taxes or the goodwill and the
                           Sellers shall within ten (10) Business Days after the
                           determination of the Final May 31 Financial

                           Notes (the "Revised May 31 Dividend Notes"); and

                  (iv)     the May 31 Dividend Notes and, if applicable, the
                           Revised May 31 Dividend Notes shall be non-recourse

                           by, and payable only with the proceeds of, the
                           Sellers' Accounts Receivable (including the proceeds
                           therefrom) in accordance with Section 8.1.

                  (d) The Sellers, TKOG and the Buyers acknowledge that
effective on May 25, 1998, the Company reduced its stated capital in respect of
the Class A shares and the Class C shares in the capital stock of the Company by
an aggregate amount of $368,122 (the "Stated Capital Amount"), and that the
Stated Capital Amount remains unpaid as of the date hereof. The Sellers, TKOG
and the Buyers agree that the Company shall pay in full the Stated Capital
Amount to the Sellers on or prior to Closing Date, and that the Company may draw
on the existing credit facility with the Toronto-Dominion Bank (as disclosed in
Section 4.9(a) of the Disclosure Schedule), up to the current limits under such
facility, for the purpose of funding such payment of the Stated Capital Amount.

                  (e) Except as expressly provided for in this Section and
except for employment remuneration paid to the Sellers in a manner consistent
with past practice or in accordance with the Employment Agreements to the extent
such agreements are effective as of the date hereof, from the date hereof until
the Closing neither the Company nor any Company Subsidiary shall, and the
Sellers shall not cause or permit the Company or any of the Company Subsidiaries
to, make any distribution to any Seller.

                  6.11 HOLDCO GUARANTIES. Each Seller shall cause each Holdco of

Guaranty substantially in the form of EXHIBIT H hereto (a "Guaranty") at the
Closing and in any event prior to such Seller transferring any Canadian Buyer
Shares that he or she owns to his or her Holdco. The Sellers acknowledge and
agree that the execution of a Guaranty by each Holdco is a material inducement
to TKOG and the Buyers to enter into this Agreement. Each Seller hereby
represents and warrants with respect to his or her Holdco that at such time as
the Holdco shall execute and deliver the Guaranty:

                  (a) The Holdco shall be duly organized, validly existing and
in good standing 

<PAGE>   42
                                                                         Page 42


under the laws of its jurisdiction of incorporation. The Holdco shall have full
corporate power and authority to own its properties and to carry on its business
as contemplated under Section 8.2. The Holdco shall be duly qualified to
transact business and in good standing in each jurisdiction wherein the nature
of the business done or the property owned, leased or operated by it requires
such qualification, except where the failure to be so qualified would not be
reasonably likely to have a Material Adverse Effect.

              (b) The Board of Directors of the Holdco shall have taken all
action required by law, its constituting document and its by-laws to authorize
the execution, delivery and performance by such Holdco of its Guaranty, and no
action of its shareholder shall have been required. The Guaranty shall have been
executed and delivered by the Holdcos in accordance with the terms of this
Section and will constitute the legal, valid and binding obligation of the
Holdco, enforceable against it in accordance with its terms, except as such
enforceability may be limited by applicable bankruptcy, insolvency, moratorium
or other laws affecting the rights of creditors generally and by general
principles of equity.

              (c) The execution, delivery and performance of the Guaranty by the
Holdco will not (i) conflict with or violate the constituting documents or
by-laws or resolutions of the directors or shareholders of the Holdco or (ii)
conflict with, violate, result in the breach of any term of, constitute a
default under, require the consent or approval of or any notice to or filing
with any third party or governmental authority under, or create an Encumbrance
on any of the shares of capital stock or the assets of the Holdco under, (x) any
note, mortgage, deed of trust or other agreement or instrument to which the
Holdco or its shareholder is a party or by which either of them or their
respective assets are bound, or (y) any law, order, rule, regulation, decree,
writ, injunction, license, approval, authorization, franchise or permit of any
governmental body having jurisdiction over it or its shareholder.

Suitability Questionnaire and Representation Letter dated the date hereof
substantially in the form of EXHIBIT I hereto.

non-resident of Canada for the purposes of the Income Tax Act (Canada) shall
deliver or has delivered to the Buyers a certificate under Section 116 of the
Income Tax Act (Canada) describing such Seller's Company Shares and setting
forth a certificate limit at least equal to the Canadian dollar equivalent of
the Purchase Price allocable to such Company Shares.


                                   ARTICLE VII

                        COVENANTS OF TKOG AND THE BUYERS

                  TKOG and the Buyers hereby covenant and agree as follows:

                  7.1 CERTAIN FILINGS. TKOG and the Buyers agree to make or
cause to be made all filings with regulatory authorities that are required to be
made by TKOG and the Buyers or their 

<PAGE>   43
                                                                         Page 43


respective affiliates to carry out the transactions contemplated by this
Agreement, and the Voting, Exchange and Support Trust Agreement. TKOG and the
Buyers agree to assist the Sellers in making all such filings, applications and
notices as may be necessary or desirable in order to obtain the authorization,
approval or consent of any governmental entity which may be reasonably required
or which the Sellers may reasonably request in connection with the consummation
of the transactions contemplated hereby.

         7.2 EFFORTS TO SATISFY CONDITIONS. TKOG and the Buyers agree to use
their respective reasonable efforts to satisfy the conditions set forth in
Articles VIII and IX hereof that are within their control.

         7.3 FURTHER ASSURANCES. TKOG and the Buyers agree to execute and
deliver such additional documents and instruments, and to perform such
additional acts, as the Sellers may reasonably request to effectuate or carry
out and perform all the terms, provisions and conditions of this Agreement and
the Voting, Exchange and Support Trust Agreement and the transactions
contemplated hereby, and to effectuate the intent and purposes hereof and
thereof.

         7.4 NOTIFICATION OF CERTAIN MATTERS. TKOG and the Buyers shall promptly
notify the Sellers of (i) the occurrence or non-occurrence of any fact or event
which would be reasonably likely (A) to cause any representation or warranty of
TKOG or the Buyers contained in this Agreement to be untrue or inaccurate in any
material respect at any time from the date hereof to the Closing Date or (B) to
cause any covenant, condition or agreement of TKOG or the Buyers in this
Agreement not to be complied with or satisfied in any material respect and (ii)
any failure of TKOG or the Buyers to comply with or satisfy any covenant,
condition or agreement to be complied with or satisfied by either of them
hereunder in any material respect; provided, however, that no such notification
shall affect the representations or warranties of TKOG and the Buyers, or the
Sellers' right to rely thereon, or the conditions to the obligations of the
Sellers. TKOG and the Buyers shall give prompt notice to the Sellers of any
notice or other communication from any third party alleging that the consent of
such third party is or may be required in connection with the transactions
contemplated by this Agreement.

         7.5 REGISTRATION.

              (a) TKOG and the Buyers shall, at their cost and expense, file no
later than the later of (i) five (5) days after the date hereof, and (ii) three
(3) days after TKOG receives all information from the Sellers which it deems
reasonably necessary to file, and use their reasonable best efforts to cause to
become effective as promptly as possible thereafter, a registration statement
(the "Resale Registration Statement") on the appropriate form pursuant to the
Act, covering the resale of all shares of the Common Stock issued and delivered
upon exchange of the Canadian Buyers Shares or the Exchangeable Shares issuable
pursuant hereto; provided that the obligation to file and maintain the
effectiveness of a Resale Registration Statement shall only exist until the
first anniversary of the Closing; further provided that in the event that after
the first anniversary of the Closing, the Sellers or the Holdcos are unable to
sell the Common Stock issued and delivered in exchange for the Exchangeable
Shares pursuant to Rule 144 promulgated under the Act (other than the volume
limitation and manner of sale limitations), TKOG and Buyers shall, at their cost
and expense, as soon as practicable after notice from a Seller or Holdco of such
inability to rely on 

<PAGE>   44
                                                                         Page 44


Rule 144, file, and use their reasonable best efforts to cause to become
effective as promptly as possible thereafter, up to two (2) additional Resale
Registration Statements which Resale Registration Statements shall only remain
effective for a forty five day period. In addition, during the period ending on
the first anniversary of the Closing, TKOG and Buyers, at the written request of
those Sellers or Holdcos who were not included in the Resale Registration
Statement referred to in the first clause of this Section 7.5(a), shall file and
use their reasonable best efforts to cause to become effective one (1)
additional Resale Registration Statement; provided that the obligation to file
and maintain the effectiveness of such second Resale Registration Statement
shall only exist until the first anniversary of the Closing Date.

              (b) Notwithstanding the provisions of Section , with respect to
any Resale Registration Statement filed or to be filed pursuant to Section , if
TKOG determines that, in its reasonable judgment, it would (because of the
existence of, or in anticipation of, any acquisition or corporate reorganization
or other transaction, financing activity, stock repurchase or development
involving TKOG or any subsidiary or the unavailability for reasons substantially
beyond TKOG's control of any required financial statements, or any other event
or condition of similar significance to the Company or any of its subsidiaries)
be disadvantageous (a "Material Development Condition") to TKOG or any of its
subsidiaries or its stockholders for such a Resale Registration Statement to
become effective or to be maintained effective or for sales of Common Stock to
continue pursuant to the Resale Registration Statement, TKOG shall,
notwithstanding Section , be entitled, upon the delivery or transmission of a
written notice from TKOG (a "Delay Notice") to such effect to all of the Sellers
or Holdcos included or to be included in such Resale Registration Statement, (i)
to cause sales of Common Stock by such Sellers or Holdcos pursuant to such
Resale Registration Statement to cease, whereupon such Sellers or Holdcos shall
immediately cease any such sales until they receive a further notice from TKOG,
or, (ii) to cause such Resale Registration Statement to be withdrawn and the
effectiveness of such Resale Registration Statement to be terminated. In the
event a Resale Registration Statement is filed and subsequently withdrawn by
reason of any existing or anticipated Material Development Condition as
hereinbefore provided, TKOG shall use its best efforts to cause a new Resale
Registration Statement covering resales by the Sellers or Holdcos of the Common
Stock to be filed with the SEC not later than the five Business Days after date
on which such Material Development Condition expires and to use its reasonable
efforts to cause such registration to be effective as soon as practicable after
such Material Development Condition expires.

              (c) Each Seller hereby covenants and agrees that he or she will
promptly provide TKOG notice of any sale made pursuant to the Resale
Registration Statement and, upon receipt of a Delay Notice, each Seller shall
cease to make any sales of Common Stock pursuant to the Resale Registration
Statement.

              (d) Notwithstanding the foregoing, if the Resale Registration
Statement is not effective at the Closing, the parties hereto shall enter into a
Registration Rights Agreement which shall be reasonably acceptable to the
parties hereto.

         7.6 EMPLOYEE BENEFITS.

              (a) Within three months after the Closing, TKOG and the Buyers
shall provide

<PAGE>   45
                                                                         Page 45


to the employees of the Company and the Company Subsidiaries retirement benefits
that are reasonably equivalent (based on, among other matters, the differences
between U.S. laws and Canadian laws relating to retirement benefits) to the
retirement benefits received by the U.S. based employees of the subsidiaries of
TKOG (the "Retirement Arrangements").

                  (b) For the purposes of determining eligibility for membership
in and entitlement to benefits under the terms of the Retirement Arrangements,
TKOG and the Buyers agree that the employees of the Company and the Company
Subsidiaries shall be credited for their period of employment with the Company
and the Company Subsidiaries to the extent permitted by such Retirement
Arrangement.

                  (c) Until the first anniversary of the Closing Date, TKOG
shall use its reasonable efforts to cause the Company and the Company
Subsidiaries to maintain any and all medical, dental, disability, life insurance
or other health benefits plans, including supplemental health benefits plans,
currently provided by the Company and the Company Subsidiaries to their
employees as of the date hereof or provide substantially comparable plans.

                  7.7 FILING TAX RETURNS. Until the fifth anniversary of the
Closing Date, TKOG shall cause the Company and the Company Subsidiaries not to
file any tax returns or reports with any governmental authority (the
"Post-Closing Returns") that have been prepared or presented on a basis that is
inconsistent with the Returns filed prior to the Closing Date, unless TKOG has
first consulted with the Agent with respect to such Post-Closing Returns and has
provided the Agent with an opportunity to discuss the basis upon which such
Post-Closing Returns have been prepared or presented.

                  7.8 LIMITATION ON FUNDAMENTAL CHANGES. Without the written
consent of the Agent, which consent shall not be unreasonably withheld or
delayed, Amalco shall not to enter into any merger, consolidation or
amalgamation, except as is permitted pursuant to Section 7.10.

                  7.9 LIMITATION ON RELIEF FROM SHAREHOLDERS AND FORMER
SHAREHOLDERS. Without the written consent of the Agent, TKOG shall not, in its
capacity as a creditor of the Company or Amalco, seek any payment from any
Seller solely by virtue of such Seller being or having been a shareholder of the
Company or Amalco.

                  7.10 LIMITATION OF UNLIMITED LIABILITY COMPANY. When TKOG
determines, in its reasonable judgment, that it no longer receives and has no
reasonable belief that it will receive a tax benefit in the future from the use
of an unlimited liability company that it will cause Amalco to amend its
constating documents, amalgamate, register as a limited liability company, or
take such other action such that Amalco is no longer an unlimited liability
company; provided, however that TKOG shall not be required to take such action
if it receives the written consent of the Agent not to take such action.


                                  ARTICLE VIII

                                                                         Page 48

              The parties hereby covenant and agree as follows:

              8.1 NOTES AND ACCOUNTS RECEIVABLE.

              (a) For purposes of this Agreement, "Notes" shall mean the May 31
Bonus Notes, the Revised May 31 Bonus Notes, the May 31 Dividend Notes and the
Revised May 31 Dividend Notes. The Notes shall be secured by the Sellers'
Accounts Receivable and the proceeds from the collection of the Sellers'
Accounts Receivable, and shall otherwise not be recourse obligations of the
Company or any Company Subsidiary. No interest shall accrue or be payable on the
Notes. The Notes shall be repaid in full in accordance with the terms thereof
and this Section 8.1 in the following order:

                  (i)      the May 31 Bonus Notes or, if applicable, the Revised
                           May 31 Bonus Notes; and

                  (ii)     the May 31 Dividend Notes or, if applicable, the
                           Revised May 31 Dividend Notes;

provided that the Notes shall not be repayable by the Company or LAMB U.S. until
after the Final May 31 Financial Statements have been determined pursuant to
Section .

                  (b) Concurrently with the delivery of the May 31 Financial
Statements pursuant to Section 8.3, the Sellers shall deliver to TKOG and the
Buyers a list of accounts receivable of each of the Company and LAMB U.S. as at
May 31, 1998 (the "Accounts Receivables List"), which list shall set forth: (w)
the name of each account debtor; (x) the total accounts receivable by each such
account debtor; (y) the amount of any reserve in respect of doubtful accounts
that has been allocated in respect of each such account receivable; and (z) the
net accounts receivable owed by each such account debtor. For greater certainty,
the Accounts Receivable List shall not include accounts receivable of the
Company Subsidiaries other than LAMB U.S. Subject to Section , the Accounts
Receivable List shall also designate, as to each account receivable, whether;

                  (i)      the account receivable is to be for the benefit of
                           the Sellers for the purposes of repayment of the
                           Notes (a "Sellers' Account Receivable"); or

                  (ii)     the account receivable is to be for the benefit of
                           the Buyers or the Company and the Company
                           Subsidiaries (a "Buyer's Account
                           Receivable").

                  (c)      The aggregate amount of the Sellers' Accounts
                           Receivable:

                  (i)      shall be net of reserves in respect of doubtful
                           accounts allocated to each individual Sellers'
                           Account Receivable;

                  (ii)     shall be up, to but not in excess of, the aggregate
                           principal amounts outstanding under the Notes;

<PAGE>   47
                                                                         Page 47


                  (iii)    shall not include any retainers paid by any account
                           debtor to the debtor to the Company or the Company
                           Subsidiaries; and

                  (iv)     shall include any account receivable of the Company
                           or LAMB U.S. that has been entirely written off as
                           uncollectible as at May 31, 1998, notwithstanding
                           that such account receivable is not identified on the
                           Accounts Receivables List; provided, however that the
                           amount of each such account receivable shall be zero
                           for the purposes of clause (ii) of this Section
                           8.1(c).

                  (d) In the event that any of the amounts set forth on the
Accounts Receivable List are changed as a result of the Closing Audit, the
Sellers shall, within ten (10) Business Days after the determination of the
Final May 31 Financial Statements pursuant to Section , prepare and deliver to
TKOG and the Buyers a revised Accounts Receivable List (which, for greater
certainty, may set forth a revised designation of accounts receivable as between
the Sellers' Accounts Receivable and Buyer's Account Receivable), such that the
aggregate amount of Sellers' Accounts Receivable identified on the revised
Accounts Receivable List is in accordance with Section .

                  (e) The Sellers' Account Receivables and the proceeds from the
collection of the Sellers' Accounts Receivables shall remain the property of the
Company and LAMB US, as the case may be, subject to the payment obligations
under the Notes and the Sellers' security interest in such receivables and
proceeds, all in accordance with the Notes.

                  (f) The Company and LAMB U.S. shall each establish a separate,
interest-bearing bank account at the same financial institution where each of
the Company and LAMB U.S. currently conduct its banking business (the "Trust
Accounts"), which shall be in the name of the Company and LAMB U.S.,
respectively, and shall designate Michael Bass, or such other person as may by
appointed by the Sellers as Account Trustee pursuant to Section , as the sole
Person authorized to make withdrawals from the Trust Accounts. Except as
expressly provided for in Section , none of TKOG, the Buyers, the Company or any
of the Company Subsidiaries shall; (i) be entitled to withdraw, or have any
right of recourse to or set-off against, any funds held, or required to be
deposited, in the Trust Accounts at any time, or (ii) encumber or pledge any
funds held in the Trust Accounts as security in any manner.

                  (g) Upon receipt by the Company or LAMB U.S. of any proceeds
from the collection of a Sellers' Account Receivable, the Company or LAMB U.S.,
as the case may be, shall forthwith deposit such proceeds into its respective
Trust Account and shall provide the Account Trustee with the names of the
debtors from which such proceeds were collected. Each of the Sellers
acknowledges and agrees that the Company and LAMB U.S. shall have no liability
under or with respect to the Notes or the payment thereof other than to deposit
the proceeds from any Sellers' Account Receivable into the appropriate Trust
Account. Subject to Sections 8.1(k) and (l), the Account Trustee may from time
to time withdraw amounts from the Trust Accounts and pay such amounts to the
Sellers in satisfaction of all or a portion of the amounts outstanding under the
Notes. Upon receipt of such payment by the Sellers, the Company or LAMB U.S., as
the case may be, shall be deemed to have paid the Notes, in the order prescribed
in Section 8.1(a), to the extent of such payment, and upon receipt by the
Sellers of payment equal to the aggregate principal

<PAGE>   48
                                                                         Page 48

amount outstanding under each of the Notes, the Account Trustee shall on behalf
of the Sellers acknowledge repayment in full of such Notes.

              (h) The Sellers hereby appoint Michael Bass as trustee (the
"Account Trustee") of all amounts paid by the Company or LAMB U.S. into the
Trust Accounts pursuant to Section . In the event the Account Trustee shall die
or resign or otherwise terminate his status as such, the successor shall be any
Seller appointed by the Account Trustee or, in the case of the death of the
Account Trustee or in the event that the Account Trustee fails to appoint a
successor after a vacancy has been created, elected by the vote or written
consent of a majority in interest of the Sellers.

              (i) The Sellers' Accounts Receivable shall be collected in a
manner consistent with past practice and consistent with the collection of all
other accounts receivable of the Company, the Company Subsidiaries and/or LAMB
U.S., provided that the Company, the Company Subsidiaries and LAMB U.S. shall
not be required to pay for any costs or expenses associated with any third party
collection efforts.

              (j) If the Company or LAMB U.S. receives proceeds from the
collection of accounts receivable from an account debtor that owes Sellers'
Accounts Receivable, Buyer's Accounts Receivable or any other accounts
receivable, such proceeds, shall first be attributed to the invoice, if any,
specified by such account debtor as the invoice being paid and if no invoice in
respect of an account receivable is specified, such proceeds shall be attributed
to the Sellers' Accounts Receivable up to the full amount of the Sellers'
Accounts Receivable owed by such account debtor. Once the full amount of the
Sellers' Accounts Receivable owed by such account debtor has been repaid and the
proceeds have been deposited by the Company or LAMB U.S. into the Trust Accounts
in accordance with Section 8.1(h), any subsequent collections by the Company
and/or LAMB U.S. from such account debtor shall be on account of the Buyer's
Accounts Receivable owed by such account debtor up to the full amount of the
Buyer's Accounts Receivable owed by such account debtor. Once the full amount of
the Buyer's Accounts Receivable owed by such account debtor has been repaid, any
subsequent collections by the Company or LAMB U.S. of accounts receivable billed
after the date hereof shall be on account of any other account receivable owed
by such account debtor.

              (k) In the event that the aggregate proceeds from the collection
of the Sellers' Accounts Receivable exceed the aggregate principal amounts
outstanding under the Notes, such excess shall be on account of the Sellers and
shall be deemed to be an increase of the Cash Purchase Price. In the event that
the aggregate proceeds from the collection of the Sellers' Accounts Receivable
does not equal or exceed the aggregate principal amounts outstanding under the
Notes, the full amount of such deficiency shall be deemed to be in respect of
the May 31 Dividend Notes or, if applicable, the Revised May 31 Dividend Notes
up to the aggregate principal amounts outstanding under such Notes.

              (l) Until such time as the total funds held in the Trust Accounts
exceed the equivalent of $150,000 (the "WIP Holdback"), the Account Trustee
shall not, without the prior written consent of the Buyers, distribute any funds
from any Trust Accounts to any Seller. At any time thereafter, the Account
Trustee shall not distribute any funds from the Trust Accounts if such

<PAGE>   49
                                                                         Page 49


distribution would cause the total funds held in the Trust Accounts to be less
than the WIP Holdback. Notwithstanding the foregoing, once the conditions for
the release of the WIP Holdback set out in Section have been satisfied, the
foregoing restrictions on distributions of the funds in the Trust Accounts shall
no longer apply.

              (m) The Company and LAMB U.S. shall withhold any and all amounts
on accounts of taxes payable by the Sellers in connection with the payments
pursuant to Sections 6.10(a) and in respect of the Notes and shall remit such
amounts to the appropriate taxation authority.

              (n) Any interest accrued on the funds held in the Trust Accounts
shall be for the benefit of the Sellers and such interest shall not be
considered as satisfaction in any way of the obligations under the Notes;
provided that any interest accrued on the amount of the WIP Holdback shall be
paid to the Sellers or the Company, as the case may be, in the same manner as
the WIP Holdback is paid.

         8.2   CORPORATE ACTIONS REQUIRED IN CONNECTION WITH CANADIAN BUYER.

              (a) As soon as practicable after the date hereof, but in any event
no later than three (3) Business Days prior to the Closing Date, the Sellers
shall cause the Company to be continued under the NS Act as a limited liability
company.

              (b) Immediately following the continuance described above, but
prior to the Closing Date, Sellers and TKOG shall cause the Company and Canadian
Buyer, respectively, to apply for and obtain an order of the Supreme Court of
Nova Scotia under Section 134 of the NS Act, approving the amalgamation of the
Company and Canadian Buyer (the "Amalgamation Order"), which order will be held
in trust by the solicitors for the Sellers pending and subject to the Closing.

              (c) Immediately following the Closing and on the Closing Date, the
following actions will be completed in the following sequential order:

                  (i)      those Sellers, if any, who have so designated in
                           writing to Canadian Buyer on or prior to the Closing
                           Date, shall be entitled to transfer any or all of the
                           Canadian Buyer Shares received by them pursuant to
                           Section to any corporation so designated by them (a
                           "Holdco");

                  (ii)     those Sellers, if any, who have so designated in
                           writing to TKOG and Canadian Buyer at least five (5)
                           Business Days prior to the Closing Date, shall
                           deliver a Retraction Request (as defined in the Buyer
                           Share Conditions) in accordance with the Buyer Share
                           Conditions, and TKOG shall be deemed to have
                           exercised its Retraction Call Right (as defined in
                           the Buyer Share Conditions) in respect of the
                           Canadian Buyer Shares subject to such Retraction
                           Request, and such Sellers shall be deemed to have
                           exchanged such Canadian Buyer Shares, upon delivery
                           of such Retraction Request to

                                                                         Page 50


                           Canadian Buyer, with the intent that Common Stock
                           shall be delivered as soon as practicable following
                           the Closing Date; and

                  (iii)    Canadian Buyer and the Company shall be amalgamated
                           (the "Amalgamation") by way of Amalgamation Agreement
                           under the NS Act and the resulting company ("Amalco")
                           will be an unlimited liability company under the NS
                           Act. Amalco will have an authorized capital of
                           100,000,000 common shares and 1,000,000 exchangeable
                           shares ("Exchangeable Shares") having rights,
                           privileges, restrictions and conditions attaching
                           thereto identical to the Buyer Share Conditions.

                           Upon the Amalgamation, the shares of each of Canadian
                           Buyer and the Company will be converted into shares
                           of Amalco or cancelled as follows:

                           A.       all of the issued and outstanding common
                                    shares in the capital of Canadian Buyer will
                                    be converted into common shares in the
                                    capital of Amalco on the basis of 1 common
                                    share of Amalco for each common share of
                                    Canadian Buyer;

                           B.       all of the issued and outstanding Canadian
                                    Buyer Shares will be converted into an
                                    equivalent number of Exchangeable Shares;
                                    and

                           C.       all of the issued and outstanding shares in
                                    the capital of the Company will be cancelled
                                    without any repayment of capital in respect
                                    thereof.

                  (d) The parties agree that the Voting, Exchange and Support
Trust Agreement shall continue to apply after the Amalgamation such that the
rights of, and the obligations of TKOG to, the holders of Exchangeable Shares
shall, after the Amalgamation, be identical to such rights and obligations in
respect of the holders of Canadian Buyer Shares under the Voting, Exchange and
Support Trust Agreement immediately prior to the Amalgamation.

                  (e) For the purposes of clause (ii) of Section 8.2(c), TKOG,
Buyer and the Sellers shall waive all requirements in Article 6 of the Buyer
Share Conditions regarding time periods for giving notice in connection with the
delivery of a Retraction Request, such that the effective time for the
redemption or purchase of the Canadian Buyer Shares pursuant to a Retraction
Request delivered on the Closing Date shall be deemed to be prior to the
Amalgamation.

                  8.3      POST-CLOSING ADJUSTMENTS.

                  (a) Within ten (10) Business Days after May 31, 1998, the
Sellers shall provide the Buyers with draft consolidated financial statements of
the Company and the Company Subsidiaries as at and for the four month period
ending May 31, 1998 (the "May 31, 1998 

<PAGE>   51
                                                                         Page 51


Financial Statements"). The May 31, 1998 Financial Statements shall have been
prepared in accordance with GAAP applied on a basis that is consistent with the
Financial Statements and shall fairly present in all material respects the
consolidated financial condition of the Company and the Company Subsidiaries as
at and for May 31, 1998. In addition, the May 31, 1998 Financial Statements
shall be prepared using the same accounting principles and practices, including
any policies or practices with respect to the establishment of reserves for
work-in-process and accounts receivable, utilized in the preparation of the
Financial Statements. Notwithstanding the foregoing, the May 31, 1998 Financial
Statements will not include a statement of changes in financial position and
will include comparative figures in respect of the year ended January 31, 1998
compared to the four months ended May 31, 1998.

                  (b) Following the Closing, the Buyers and its representatives
shall conduct an audit of the books and records of the Company and the Company
Subsidiaries as of and for the four month period ended May 31, 1998 (the
"Closing Audit"). The Closing Audit shall be conducted in a manner such that
Arthur Andersen LLP, TKOG's independent auditors, could issue a report thereon.
The Closing Audit shall be completed within forty-five (45) days after the
delivery of the May 31, 1998 Financial Statements. The Buyers shall provide the
Agent with a reasonable opportunity to discuss any proposed adjustments to the
May 31, 1998 Financial Statements proposed by Arthur Andersen LLP prior to the
delivery of the Audit Report.

                  (c) No later than the forty-sixth (46th) day after the
delivery of the May 31, 1998 Financial Statements, the Buyers shall deliver to
Tedd Avey or his designee a copy of any proposed adjustments to the May 31, 1998
Financial Statements based on the Closing Audit (the "Audit Report"). Within
fifteen (15) Business Days after the delivery of the Audit Report to Tedd Avey
or his designee, the Designated Sellers shall deliver to the Buyers a written
notice (the "Dispute Notice") of any objections to any item or amount set forth
in the Audit Report, specifying in reasonable detail the reason for each
objection and the amount of each proposed adjustment (the "Disputed Items"). The
determination in the Audit Report of any item not objected to by the Designated
Sellers in the Dispute Notice shall be final, binding and conclusive on all the
parties to this Agreement. After receipt of the Dispute Notice, the Designated
Sellers and the Buyers and their representatives and advisors shall meet to
discuss the Disputed Items in an effort to reach agreement with respect thereto.
If the Designated Sellers and the Buyers are able to reach an agreement as to
any Disputed Items, then such determination as agreed upon in writing as to such
Disputed Items shall become final, binding and conclusive upon all the parties
and such items shall no longer be Disputed Items. If the Designated Sellers and
the Buyers are unable to reach an agreement in writing as to any Disputed Items
within ten (10) Business Days after receipt of the Designated Sellers' notice of
Disputed Items, then the unresolved Disputed Items shall be submitted for
resolution as provided in Section for a determination that shall be final,
binding and conclusive on all the parties to this Agreement.

                  (d) If during the ten Business Day period referred to in
Section the Designated Sellers and the Buyers cannot resolve all such Disputed
Items, the parties shall promptly thereafter, but in no event more than five
Business Days thereafter, cause a partner of Ernst & Young Chartered
Accountants, located in its Toronto, Ontario office ("E&Y"), promptly to review
this Agreement, the May 31, 1998 Financial Statements, the Audit Report, the
Dispute Notice and the unresolved Disputed Items for purposes of resolving the
unresolved Disputed Items. In making 

<PAGE>   52
                                                                         Page 52


such calculation, E&Y shall make a determination in accordance with the terms
and provisions of this Agreement only of unresolved Disputed Items and in the
case of all other items shall use the amounts which are agreed upon by the
Designated Sellers and the Buyers. E&Y shall deliver to the Designated Sellers
and the Buyers, as promptly as possible but in no event later than twenty (20)
Business Days after the parties submit their dispute to such accounting firm, a
report setting forth its resolution of the unresolved Disputed Items. Such
report shall be final, binding and conclusive upon the parties hereto. The cost
of such report shall be borne equally by the Sellers, on the one hand, and the
Buyers, on the other hand. Each party agrees that neither it nor its affiliates
currently contemplates retaining E&Y for any substantial engagement having a
purpose other than the performance of the services set forth herein. The May 31,
1998 Financial Statements, as adjusted pursuant to the provisions of this
Section , shall be referred to for purposes of this Agreement as the "Final May
31, 1998 Financial Statements."

                  (e) For the purposes of conducting the Closing Audit and
determining the Final May 31, 1998 Financial Statements, TKOG, the Buyers and
the Sellers acknowledge and agree that the fixed assets of the Company and the
Company Subsidiaries, which include the accounting and computer systems and
related equipment, shall be reflected on the consolidated balance sheet of the
Company and the Company Subsidiaries on a basis consistent with past practice;
provided, however that such assets have been reflected in accordance with GAAP;
and provided, further that, with respect to the accounting and computer systems
and related equipment, such fixed assets have been amortized on a 30% declining
balance basis consistent with past practice.

              8.4 IRREVOCABLE APPOINTMENT OF AGENT. By the execution and
delivery of this Agreement, including any counterparts hereof, each Seller
hereby irrevocably constitutes and appoints Tedd Avey with full power of
substitution, to be the Sellers' attorney and representative (the "Agent") to
take any and all actions and to execute any and all documents as the Agent may
deem necessary or appropriate in connection with the Closing or the transactions
contemplated by this Article VIII, in the name of each Seller and on each
Seller's behalf in any way that such Seller could do if personally present and
acting. If TKOG or the Buyers are required to provide any notice or take any
action with respect to any Seller in connection with the Closing or the
transactions contemplated by Article VIII, each of the Sellers hereby agrees
that TKOG or the Buyers shall be able to take such action against, or provide
such notice to, the Agent. Unless there is no existing person that has been
designated to act as Agent by the Sellers, all rights of the Sellers that may be
exercised in connection with the Closing or the transactions contemplated by
Article VIII shall be exercised by the Sellers only through or by the Agent on
behalf of the Sellers and the Buyers and TKOG shall not be required to take
directions from any other Seller for so long as such Agent continues to act and
has not otherwise been removed as Agent. In the event the Agent shall die or
resign or otherwise terminate his status as such, the successor shall be any
Seller appointed by the Agent or, in the case of the death of the Agent or where
the Agent fails to appoint a successor after a vacancy has been created, elected
by the vote or written consent of a majority of the Sellers. The power of
attorney granted in this Section 8.4 is not intended to be a continuing power of
attorney within the meaning of and governed by the Substitute Decisions Act
(Ontario), or any similar power of attorney under equivalent legislation in any
of the provinces or territories of Canada (a "CPOA"). The execution of this
Agreement shall not terminate any such CPOA previously granted by the Sellers
and shall not be terminated by the execution by the Sellers in the future of any
CPOA.

         12.2 INDEMNIFICATION BY THE SELLERS.

              (a) Subject to Sections 12.2(b) and , the Designated Sellers
shall, jointly and severally, and the other Sellers shall, severally and not
jointly, indemnify and hold harmless TKOG, the Buyers, the Company, the Company
Subsidiaries and their respective directors, officers and employees (the
"Indemnified Parties") from and against any Loss incurred or suffered by such
Person as a result of, arising from or in connection with:
<PAGE>   58
                                                                         Page 58



                  (i) a breach by a Seller of any representation or warranty
         made by such Seller in this Agreement or in any Schedule or certificate
         delivered pursuant hereto; and

                 (ii) a failure by a Seller to perform or comply with any
         covenant or agreement on the part of such Seller contained herein; and

                 (iii) the lease in respect of 600 North Pearl in Dallas, Texas,
         referred to in Section 4.11 of the Disclosure Schedule.

The amount paid pursuant to the preceding sentence shall be paid to the Buyers
or, at the Buyers' election, to the Company and shall be the amount required to
put the Buyers or the Company, as the case may be, in the position it would have
been in had such representation, warranty, covenant or agreement not been
breached. Any payment made by a Seller under this Section 12.2 shall be treated
as a reduction in the aggregate consideration received by such Seller from Buyer
pursuant to this Agreement.

              (b) Notwithstanding Section , the Sellers shall not have any
obligation to indemnify Indemnified Parties from and against any Loss as a
result of, arising from or in connection with clause (i) of Section : (i) until
the Indemnified Parties have suffered aggregate Losses, by reason of all such
breaches (excluding any such individual breaches or series of related breaches
resulting in Losses of less than $U.S.10,000; provided, however, that all Losses
for individual breaches or series of related breaches in excess of $U.S.10,000
shall be included) in excess of $U.S.95,000, provided that once the Indemnified
Parties' aggregate Losses exceed $U.S.95,000, the Sellers shall indemnify the
Indemnified Parties for all Losses in excess of $U.S.47,500; or (ii) to the
extent the aggregate Losses the Indemnified Parties have suffered by reason of
all such breaches of representations and warranties of the Sellers in this
Agreement or in any Schedule or certificate delivered pursuant hereto exceed the
Purchase Price (the "Cap"), in the absence of fraud or intentional
misrepresentation, the Sellers will have no obligation to indemnify the
Indemnified Parties from and against further Losses in excess of the Cap. For
purposes of determining whether an event described in clause (i) of Section
12.2(a) has occurred, any requirement in any representation or warranty that an
event or fact be material or have a Material Adverse Effect for such event or
fact to constitute a misrepresentation or breach of such warranty shall be
ignored.

              (c) Notwithstanding anything to the contrary contained in Section
12.2(b) or anywhere else in this Agreement, the Designated Sellers shall,
jointly and severally, and the other Sellers shall, severally and not jointly,
indemnify and hold harmless, the Indemnified Parties from and against any Loss
incurred or suffered by such Person after the Closing Date as a result of,
arising from or in connection with:

                  (i) any fraudulent acts or intentional misconduct, which
         occurred prior to the Closing Date, by any of the Sellers, the Company,
         any of the Company Subsidiaries or any of their respective employees
         against a third party; PROVIDED, HOWEVER, that this Section shall not
         apply to negligence; and PROVIDED FURTHER that any such claim must have
         been

<PAGE>   59
                                                                         Page 59

         asserted by such third party prior to the second anniversary of the
         date hereof;

                   (ii) the failure of the Company or the Company Subsidiaries
         to collect the full amount of the Buyer's Accounts Receivable after a
         reasonable period of time, provided that the Company or the Company
         Subsidiaries have used reasonable efforts, consistent with past
         practice, to collect such accounts receivable; and

                   (iii) any claim, action or other proceeding commenced by any
         Seller against the Indemnified Parties challenging the validity of the
         distributions to the Sellers contemplated by Section .

                  (d)      WORK-IN-PROGRESS.

                  (i) The Designated Sellers, jointly and severally, and the
         other Sellers, severally and not jointly, hereby indemnify the
         Indemnified Parties against, and hold them harmless from, any failure
         to collect any amounts relating to any work-in-process of the Company
         and the Company Subsidiaries as set forth in the balance sheet in the
         Final May 31, 1998 Financial Statements (the "Closing Audit WIP") that
         remains uncollected after the second anniversary of the Closing Date
         (the "WIP Termination Date").

                  (ii) The Sellers' indemnification obligations under Section
         12.2(d)(i) shall be limited to an amount equal to the Closing Audit WIP
         less $150,000 (the "Threshold WIP") and shall cease to have effect at
         such time as an amount equal to the Threshold WIP has been billed and
         collected in accordance with Section . If an amount equal to the
         Threshold WIP has not been billed and collected by the WIP Termination
         Date, the Sellers' indemnification obligations shall be satisfied by
         payment by the Sellers to the Buyers of an amount (the "WIP Shortfall")
         equal to the difference between the Threshold WIP and the amount of
         billed and collected Closing Audit WIP as at the WIP Termination Date,
         and such amount shall be deemed to be a reduction in each of the
         Sellers' proportionate amount of the Cash Purchase Price. Any amount
         due and owing pursuant to this Section shall first be satisfied by the
         payment to the Buyers of the WIP Holdback. If the WIP Shortfall exceeds
         the WIP Holdback, Sellers shall promptly pay to Buyers the amount of
         such difference in accordance with the provisions of this Section .

                  (iii) All amounts in respect of any work-in-process of the
         Company or the Company Subsidiaries that are billed after May 31, 1998
         shall be deemed to be amounts billed in respect of the Closing Audit
         WIP, until the aggregate amount billed exceeds the Threshold WIP. All
         proceeds collected by the Company or the Company Subsidiaries after May
         31, 1998 in respect of accounts receivable (other than the Sellers'
         Accounts Receivable and the Buyer's Accounts Receivable) shall, subject
         to Section 8.1(j), be deemed to be amounts collected in respect of the
         Closing Audit WIP, until the aggregate amount collected exceeds the
         Threshold WIP. Once the Threshold WIP has been billed and collected,
         the conditions for the release of the WIP Holdback shall be deemed to
         have been satisfied for the purposes of Section , and the Buyers shall
         notify the Account Trustee to this effect.

                                                                         Page 60


                  (iv) TKOG shall cause the Company to calculate the amount of
         billed and collected Closing Audit WIP, and to give notice of these
         amounts to the Account Trustee on behalf of the Sellers, on a quarterly
         basis and at the earlier of: (i) such time as an amount equal to the
         Threshold WIP has been billed and collected; and (ii) the WIP
         Termination Date.

                  (e) To the maximum extent permitted by law, each Seller hereby
releases from any and all manner of claims, demands, causes of action,
obligations, damages or liabilities whatsoever of every kind and nature, at law
or in equity, known or unknown, and whether or not discoverable, which such
Seller has or may have for any period prior to the Closing, and any claim for
attorneys' fees or costs incurred against any other Seller, TKOG or the Buyers,
except for (i) claims against TKOG or the Buyers relating to their respective
indemnification obligations hereunder or (ii) any employment-related claim.

                  (f) No Seller shall be liable to indemnify or hold harmless
any Indemnified Party from or against any Loss incurred or suffered by such
Indemnified Party as a result of, arising from, or in connection with any breach
of representation, warranty, covenant or agreement on the part of any other
Seller or Sellers contained in any Employment Agreement, including without
limitation any covenants regarding non-competition.

                  (g) Notwithstanding anything to the contrary contained in this
Article XII, no Seller other than a Designated Seller shall be liable to
indemnify or hold harmless any Indemnified Party for an aggregate amount in
excess of each Seller's proportionate amount of the Purchase Price, and no
Designated Seller shall be liable to indemnify or hold harmless any Indemnified
Party for an aggregate amount in excess of each Designated Seller's
proportionate amount of the Purchase Price, plus an amount equal to each
Designated Sellers' proportionate amount (as amongst themselves) of U.S.
$300,000.

                  12.3     INDEMNIFICATION BY TKOG AND THE BUYERS.

                  (a) TKOG and the Buyers shall jointly and severally indemnify
and hold harmless each Seller from and against any Loss incurred or suffered by
such Seller as a result of, arising from or in connection with:

                  (i) a breach by TKOG or the Buyers of any representation or
         warranty made by TKOG or the Buyers in this Agreement and the Voting,
         Exchange and Support Trust Agreement or in any Schedule or certificate
         delivered pursuant hereto or in the Voting, Exchange and Support Trust
         Agreement; and

                 (ii) a failure by TKOG or the Buyers to perform or comply with
         any covenant or agreement on the part of TKOG or the Buyers contained
         herein, including any covenant contained in Article VII, or in the
         Voting, Exchange and Support Trust Agreement.

                  (b) In connection with the Resale Registration Statement, the
Sellers shall furnish, in writing, to TKOG such information as TKOG may
reasonably request, including any and all information with respect to the
distribution method intended to be used by any Seller. 

<PAGE>   61
                                                                         Page 61


TKOG shall indemnify and hold harmless, in the case of the Resale Registration
Statement, each Seller from and against any Loss suffered or incurred by such
Seller, as a result, of arising from, or in connection with any action or
proceeding, whether commenced or threatened, pursuant to the Act that is based
upon any untrue statement or alleged untrue statement of any material fact
contained in the Resale Registration Statement, any preliminary prospectus,
final prospectus or summary prospectus contained therein, or any amendment or
supplement thereto, or any omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances in which they were made, not misleading;
provided, however, that TKOG shall have no obligation to indemnify any Seller if
any material misstatement or omission was corrected by TKOG and such corrected
preliminary prospectus, final prospectus or prospectus summary or amendment or
supplement thereto was delivered to such Seller and not delivered by such Seller
to the purchaser of the Common Stock. TKOG shall reimburse each such Seller for
any legal or any other expenses reasonably incurred by them in connection with
investigating or defending any such Loss. TKOG shall not be liable to indemnify
or hold harmless any person pursuant to this Section 12.3(b) to the extent that
any such Loss results or arises, is in connection with, or is based upon, an
untrue statement or alleged untrue statement or omission or alleged omission
made in the Resale Registration Statement or any such preliminary prospectus,
final prospectus, summary prospectus, amendment or supplement in reliance upon
and in conformity with information furnished to TKOG, in writing, by any Seller
for purposes of inclusion therein. The foregoing indemnity shall remain in full
force and effect regardless of any investigation made by or on behalf of such
Seller and shall survive the transfer of the Common Stock by any such Seller (or
his or her Holdco).

              12.4 ASSUMPTION OF DEFENSE. An indemnified party shall promptly
give notice to each indemnifying party after obtaining Knowledge of any matter
as to which recovery may be sought against such indemnifying party because of
the indemnity set forth above, and, if such indemnity shall arise from the claim
of a third party, shall permit such indemnifying party to assume the defense of
any such claim or any litigation resulting from such claim; PROVIDED, HOWEVER,
that failure promptly to give any such notice shall not affect the
indemnification provided under this Article XII, except to the extent such
indemnifying party shall have been prejudiced as a result of such failure.
Notwithstanding the foregoing, an indemnifying party may not assume the defense
of any such third-party claim if it does not demonstrate to the reasonable
satisfaction of the indemnified party that it has adequate financial resources
to defend such claim and pay any and all Losses that may result therefrom, or if
the claim (i) is reasonably likely to result in imprisonment of the indemnified
party, (ii) is reasonably likely to result in a criminal penalty or fine against
the indemnified party the consequences of which would be reasonably likely to
have a material adverse effect on the indemnified party unrelated to the size of
such penalty or fine, or (iii) is reasonably likely to result in an equitable
remedy which would materially impair the indemnified party's ability to exercise
its rights under this Agreement, or impair TKOG's or Canadian Buyer's right or
ability to operate the Company. If an indemnifying party assumes the defense of
such third party claim, such indemnifying party shall agree prior thereto in
writing that it is liable under this Article XII to indemnify the indemnified
party in accordance with the terms contained herein in respect of such claim,
shall conduct such defense diligently, shall have full and complete control over
the conduct of such proceeding on behalf of the indemnified party and shall, in
his or her or its sole discretion, have the right to decide all matters of
procedure, strategy, substance and settlement relating to such proceeding;
PROVIDED, HOWEVER, that any counsel chosen by such indemnifying party to conduct

<PAGE>   62
                                                                         Page 62



such defense shall be reasonably satisfactory to the indemnified party. The
indemnified party may participate in such proceeding and retain separate
co-counsel at its sole cost and expense (except that the indemnifying party
shall be responsible for the fees and expenses of one separate co-counsel for
the indemnified party to the extent the indemnified party is advised by its
counsel that either (x) the counsel the indemnifying party has selected has a
conflict of interest or (y) there are legal defenses available to the
indemnified party that are different from or additional to those available to
the indemnifying party), and the indemnifying party will not without the written
consent of the indemnified party consent to the entry of any judgment or enter
into any settlement with respect to the matter which does not include a
provision whereby the plaintiff or the claimant in the matter releases the
indemnified party from all liability with respect thereto. Failure by an
indemnifying party to notify the indemnified party of its election to defend any
such claim or action by a third party within thirty (30) days after notice
thereof shall have been given to such indemnifying party by the indemnified
party shall be deemed a waiver by such indemnifying party of its right to defend
such claim or action.

              12.5 NON-ASSUMPTION OF DEFENSE. If no indemnifying party is
permitted or elects to assume the defense of any such claim by a third party or
litigation resulting therefrom, the indemnified party shall diligently defend
against such claim or litigation in such manner as it may deem appropriate and,
in such event, the indemnifying party or parties shall promptly reimburse the
indemnified party for all reasonable out-of-pocket costs and expenses, legal or
otherwise, incurred by the indemnified party and its affiliates in connection
with the defense against such claim or litigation, as such costs and expenses
are incurred. Any counsel chosen by such indemnified party to conduct such
defense must be reasonably satisfactory to the indemnifying party or parties,
and only one counsel shall be retained to represent all indemnified parties in
an action (except that if litigation is pending in more than one jurisdiction
with respect to an action, one such counsel may be retained in each jurisdiction
in which such litigation is pending).

              12.6 INDEMNIFIED PARTY'S COOPERATION AS TO PROCEEDINGS. The
indemnified party will cooperate in all reasonable respects with any
indemnifying party in the conduct of any proceeding as to which such
indemnifying party assumes the defense. For the cooperation of the indemnified
party pursuant to this Section , the indemnifying party or parties shall
promptly reimburse the indemnified party for all reasonable out-of-pocket costs
and expenses, legal or otherwise, incurred by the indemnified party or its
affiliates in connection therewith, as such costs and expenses are incurred.

              12.7 LIMITATION ON LOSSES. (a) The amount of any Loss incurred or
suffered by any Indemnified Party, any Seller shall be net of: (i) any insurance
proceeds received by such Person in connection with the breach, failure or other
event which gave rise to such Loss; and (ii) any reduction in taxes payable by
such Person as a result of the deductibility of such Loss against taxable
income.

              (b) The amount of any Loss incurred or suffered by any Indemnified
Party shall be increased by any Tax incurred or reasonably expected to be
incurred as a result of or related to any such Loss, including without
limitation any Tax related to the inclusion in gross income of insurance
proceeds or a payment.

expenses incurred by the Company for the benefit of the Sellers prior to May 31,
1998 shall be paid by the Company and all expenses incurred by the Company for
the benefit of the Sellers after May 31, 1998 shall be paid out of the amounts
held in the Trust Account prior to any distribution to the Sellers. TKOG and the
Buyers shall pay all costs and expenses incurred by or on behalf of the Sellers
in connection with the matters described in Section , including any and all
reasonable fees, costs or expenses incurred by or on behalf of the Sellers in
connection with:

                  (a) the advice and representation of the law firm of Stewart
McKelvey Stirling Scales, or such other Nova Scotia counsel as may be retained

Agreement;

DesLauriers & Binnington solely in respect of matters pertaining to the
transactions contemplated by Section ;

                  (c) the incorporation of Holdcos for those Sellers who will
receive and retain Canadian Buyer Shares; and

                  (d) the preparation and filing of annual tax and other
corporate returns in respect of each Holdcos until the second December 31 after
the Holdco no longer holds any Exchangeable Shares in an amount not to exceed
$2,500 per year; PROVIDED, however, that Sellers shall indemnify the Indemnified
Parties and any of their affiliates or agents for any Loss such Persons may
suffer as a result of any inaccuracy in any information provided by Sellers in
connection with such returns.

                  13.2 NON-SOLICITATION. From the date hereof until the Closing
Date or the termination of this Agreement pursuant to Article XI hereof, none of
the Sellers nor the Company (or its officers, directors, employees, agents or
representatives) shall encourage, solicit, entertain or participate in an offer
from, engage in discussions or otherwise negotiate with, or provide any
information to, any party (other than TKOG, the Buyers and their respective
officers, directors, employees, agents or representatives) with respect to the
sale or merger of the Company or any Company Subsidiary or any sale or other
transfer of their respective assets or capital stock.

                  13.3 ENTIRETY OF AGREEMENT. This Agreement (including the
Disclosure Schedule and all other Schedules and Exhibits hereto), together with
the other documents and certificates delivered hereunder, state the entire
agreement of the parties, merge all prior negotiations, agreements and

binding upon, inure to the benefit of, and be enforceable by the parties hereto
and their respective heirs, personal representatives, legatees, successors and
permitted assigns. Except as otherwise expressly provided in Article XII, this
