     CN has provided to SLQ the Information Binder, which contains descriptions

6.6  CONFIDENTIALITY

     CN and SLQ agree that:

     (a)    Each party will treat in confidence this Agreement, including all

            preparation of this Agreement and all other related documents. The
            obligation of each party to treat such agreements, documents,
            materials and other information in confidence shall not apply to any

            such other party, or (iv) is later lawfully acquired by such party
            from other sources.

     (b)    This Agreement and any information obtained from CN shall be treated
            as confidential and shall not be disclosed to any third party (other
            than to a government or regulatory authority entitled to the
            disclosure thereof by law and to each party's affiliates,
            consultants or their respective representative, solicitors and
            accountants) except in situations where a valid judicial decision
            may order the Agreement to be disclosed either in whole or in part.
            The parties submitting the Agreement to such governmental or
            regulatory authority shall request the governmental or regulatory
            authority to preserve the confidentiality of the business sensitive
            portions of the Agreement.

     (c)    In the event the transaction contemplated herein is not completed
            and this Agreement is terminated, each party will treat in

            findings which it or any of its consultants, affiliates or their
            respective representatives, solicitors and accountants shall have
            obtained or made regarding the other party during the course of the
            negotiations relating to this Agreement, the investigation of the
            other party and the preparation of this Agreement and other
            documents relating to this Agreement, and shall promptly return to

            which may have been furnished in connection therewith.

     (d)    Other than as specified herein, neither of the parties hereto shall
            make any public announcement or disclosure concerning this
            Agreement, the transactions contemplated hereby or the information
            required to be kept confidential hereunder to any party without the
            prior written consent of the other party unless, in the written
            opinion of counsel, such party is compelled by law to do so,
            including pursuant to public disclosure requirements under
            applicable securities legislation, and then only with prior written
            notice to the other party, except that the parties acknowledge the
            Emons Transportation Group Inc., an affiliate of the Purchaser, is
            required pursuant to US securities law applicable to it to file a
            copy of this Agreement with the SEC in electronic form. Both SLQ and

ARTICLE 7 - LEASES, LICENSES, CONTRACTS AND ORDERS
- --------------------------------------------------

7.1  ASSUMED CONTRACTS AND AGENCY ORDERS
     -----------------------------------

     It is understood and agreed that the Purchased Assets will be sold subject
     to the Assumed Contracts and Agency Orders in effect on the Closing Date,
     whether or not shown on the Right-of-way Plans and whether or not recorded
     in the public land records. Subject to Section 3.4, CN represents that
     Schedule E is a list of all leases, licenses, contracts and agreements
     known to CN. CN represents and warrants that no contract not listed on
     Schedule E will have a material adverse effect on SLQ's ability to operate
     the Sherbrooke Line or to conduct its business.

7.2  BENEFITS AND OBLIGATIONS
     ------------------------

     Subject to Paragraph 3.1(d) and Section 3.4, SLQ shall, to the extent
     assignable, succeed to all of the rights and benefits and shall assume all
     of the duties and obligations under the Assumed Contracts and Agency Orders
     as and from the Commencement Date.  CN agrees to indemnify and save
     harmless SLQ against all claims or obligations associated with an Assumed
     Contract and Agency Order to the extent such claim can be attributable to
     an incident which occurred before the Commencement Date.  To CN's
     knowledge, such Assumed Contracts and Agency Orders will not have a
     material adverse effect on SLQ's ability to operate the Sherbrooke Line in
     substantially the same manner as operated by CN.  To the extent that the
     assignment of any agreement, contract, lease, commitment, or undertaking to
     be assigned, as provided herein, shall require the consent of another party
     thereto, this Agreement shall not constitute an agreement to assign the
     same if an attempted assignment would constitute a breach thereof, but CN
     agrees that it will use its best efforts to obtain the written consent of
     the other parties to all material agreements, contracts, leases,
     commitments, and undertakings to the assignment thereof, and if such
     consent is not obtained, CN will cooperate with SLQ in any reasonable
     arrangement designed to provide for SLQ the benefits under any such
     material agreements, contracts, leases, commitments, and undertakings,
     including enforcement at SLQ's cost of any and all rights of CN against
     another party thereto arising out of the breach or cancellation thereof by
     another party or otherwise.  CN makes no representation with respect to the
     effect of any failure to obtain any such consent to the transfer or
     assignment of any such material leases, licenses, contracts, or orders on
     SLQ's ability to operate the Sherbrooke Line.  Nothing herein shall require
     CN to make any payments to a lessor or other party to any such agreement or
     to incur any legal or enforcement costs in furtherance of the objectives
     described in this paragraph.

            approved by SLQ in writing;

     derived from the use of the utility right-of-way corridor shall accrue
     solely to CN.  If CN exercises its right under this provision, CN will
     provide SLQ with 30 days' written notice before undertaking any such work.
     In no event, shall CN's use of the utility right-of-way corridor interfere
     with SLQ's ability to provide uninterrupted rail service on or across the
     Sherbrooke Line, or interfere with any utility lines or other than existing
     use of the utility right-of-way corridor.

                                       22

     If works to be performed by CN for the use of the utility right-of-way
     corridor render it necessary to relocate the trackage of the Sherbrooke
     Line or portions thereof in order for SLQ to continue to provide
     uninterrupted rail service on the Sherbrooke Line, outside of the purchased
     lands, CN shall not be entitled to commence such work unless or until it
     has acquired for and on behalf of SLQ necessary contiguous land for the
     relocation of the trackage in order for SLQ to continue to provide
     uninterrupted rail service despite CN's work.  Further, if such work or the
     resulting facilities interfere with SLQ's ability to provide uninterrupted
     rail service on or over the Sherbrooke Line, CN, or its successors or
     assigns, shall bear all reasonable costs associated with any necessary
     relocation of the trackage, if such relocation is performed by SLQ and all
     costs if performed by CN or by a third party. CN shall retain an easement
     in, under and across the Purchased Lands for the purpose of constructing,
     maintaining, repairing, operating and relocating any fibre optic or utility
     facilities.  SLQ will not locate nor grant the right to any party other
     than CN to locate any other fibre optic or other utility facilities on the
     Sherbrooke Line, except for the purposes of a local network.


IN WITNESS WHEREOF the parties have executed this Agreement as of the day and

     B.  Leasing is a newly formed corporation organized under the laws of
Delaware and a wholly-owned subsidiary of SLR.

     C.  SLQ is a newly formed corporation organized under the laws of Quebec,
Canada, and a wholly-owned subsidiary of Railroad Group.
 
     D.  Lender and the U.S. Borrowers desire to amend and restate the Original
Agreement and join in Leasing and SLQ on the terms and conditions stated
hereunder in order to provide for, among other things, a loan to be made by
Lender to SLQ in connection with SLQ's acquisition of the Sherbrooke Short Line
Railroad located in Quebec, Canada (the "Sherbrooke Acquisition") and other
loans to the U.S. Borrowers to enable SLQ to finance certain capital
improvements and for other general corporate purposes of the U.S. Borrowers.

     NOW THEREFORE, in consideration of the mutual conditions and agreements
set forth in this Agreement, and for good and valuable consideration, the
receipt of which is hereby acknowledged, the Borrowers and the Lender hereby
agree as follows:

          writing, including, by telecopy, not later than 11:00 a.m. (Chicago

          notwithstanding,

                    (i)    if the Lender shall, at least one Business Day before
               the date of any requested Borrowing, notify the U.S. Borrowers or
               SLQ, as the case may be, that the introduction of or any change
               in or in the interpretation of any law or regulation makes it
               unlawful, or that any central bank or other Governmental
               Authority makes it unlawful, for the Lender to perform its
               obligations hereunder to make Offshore Rate Loans; or

                    (ii)   if the Lender is unable, after reasonable efforts,
               due to prevailing market conditions, to provide timely
               information for the determination of the Eurodollar Rate or CDOR
               Rate, as the case may be, or is otherwise unable to determine the
               Eurodollar Rate or the CDOR Rate at any time, or

                    (iii)  if the Lender has reasonably determined that the
               Eurodollar Rate or CDOR Rate is inadequate to compensate the
               Lender,

                                      -27-

          then, in any such event, the right of the Borrowers to select Offshore
          Rate Loans shall be suspended until the Lender shall notify the
          Borrowers that the circumstances causing such suspension no longer
          exist; and (A) in the case of any Offshore Rate Loans bearing interest
          at the Eurodollar Rate, each such Offshore Rate Loan shall be a Base
          Rate Loan, and (B) in the case of any Offshore Rate Loans bearing
          interest at the CDOR Rate, all such Offshore Rate Loans shall
          thereafter accrue interest at a rate to be negotiated in good faith by
          SLQ and the Lender.

               (c)  Each Notice of Borrowing shall be irrevocable and binding on
          the Borrowers.  In the case of any requested Offshore Rate Loans, the
          requesting Borrower shall indemnify the Lender against any loss,
          reasonable cost or expense incurred by the Lender as a result of any
          failure to fulfill on or before the date specified in such Notice of
          Borrowing for such Loan the applicable conditions set forth in Article
                                                                         -------

          reasonable calculations), cost or expense incurred by reason of the
          liquidation or reemployment of deposits or other funds acquired by the
          Lender to fund the requested Loan, as a result of such failure, is not
          made on such date.

               (d)  Emons, on behalf of the U.S. Borrowers and SLQ, shall notify
          the Lender in writing of the names of the officers and employees
          authorized to request any Loans on behalf of the U.S. Borrowers and
          SLQ, and shall provide the Lender with a specimen signature of each
          such officer or employee.  The Lender shall be entitled to rely
          conclusively on such officer's or employee's authority to request a
          Loan on behalf of the U.S. Borrowers or SLQ, until the Lender receives
          written notice to the contrary.  The Lender shall have no duty to
          verify the authenticity of the signature appearing on any written
          Notice of Borrowing.

               (e)  The Lender shall establish or cause to be established on its
          books in the name of the U.S. Borrowers and SLQ an account (each, a
          "Loan Account") to evidence Loans made to the U.S. Borrowers and SLQ,

          respectively.  In the case of the U.S. Borrowers, the Lender will
          credit or cause to be credited to a commercial account for each of the
          U.S. Borrowers (each a "Demand Deposit Account") maintained by Emons

          amounts credited to each such Demand Deposit Account, and advanced to
          the U.S. Borrowers as a Loan pursuant to this Agreement will be
          debited to such U.S. Borrower's Loan Account and result in an increase
          in the principal balance outstanding in the applicable Loan Account in
          the amount thereof.  In the case of SLQ, Lender shall disburse the
          Canadian Term Loan as directed by Emons on behalf of SLQ as follows:
          (i) an amount equal to C$5,900,010 shall be disbursed to the trust
          account of Ogilvy Renault, escrow agent, maintained at the Royal Bank
          of Canada in Montreal, Quebec and (ii) an

          amount equal to C$683,490 shall be disbursed to an account of SLQ at
          the Toronto office of ABN AMRO Bank Canada; both such amounts will be
          debited to SLQ's Loan Account and result in an increase in the
          principal balance outstanding in SLQ's Loan Account.  The Lender is
          hereby authorized, at its option, either (A) to endorse the date and
          amount of each Loan made by it and each repayment or prepayment of
          principal of Loans made with respect to the applicable Note on the
          schedule annexed to and constituting a part of the Note or (B) to
          record such Loans, repayments and prepayments in its books and
          records, such schedule or such books and records, as the case may be,
          constituting prima facie evidence, absent manifest error, of the
          accuracy of the information contained therein.

               results in the repayment or greater than 25% of the Available
               Canadian Term Loan Amount prior to December 21, 2003. The U.S.
               Borrowers and SLQ shall give the Lender not less than three (3)
               Business Days' prior written notice of the date on which each

               to repay the B Term Loan until the B Term Loan is paid in full
               and next to the A Term Loan to installments or reductions due in
               the inverse order of maturity until paid in full, then to the

               remitted by SLQ shall be applied to the Canadian Term Loan, to
               installments in the inverse order of maturity until paid in full;
               provided, however, that any Excess Cash Flow Payment attributable
               to Excess Cash Flow allocable to SLQ shall only be applied to the

               Available Canadian Term Loan Amount, shall be permanently reduced
               by the amount of each Mandatory Prepayment. In addition, at the
               Lender's option the Working Capital Commitment shall be
               permanently reduced on a dollar for dollar basis by the amount of
               such Mandatory Prepayments in excess of those applied to the B

          additional restrictions which exclude particular types of Accounts
          from Eligible Receivables, and (iii) to establish Eligibility
          Reserves, increase the amount thereof and add additional types of
          Eligibility Reserves. The Borrowers expressly acknowledge that the
          above referenced reductions, restrictions and additions may have the
          effect of reducing the credit available under this Agreement.

          any Loan be an Offshore Rate Loan (in the case of the Canadian Term
          Loan, such Loan shall then accrue interest at a rate to be negotiated
          in good faith by SLQ and the Lender); and (ii) in the case of the A
          Term Loan, the B Term Loan and the Working Capital Loan, the U.S.
          Borrowers shall pay interest on the Loans for which they are liable on
          the unpaid principal amount thereof at the Default Rate, such interest
          being payable on demand.

               2.8  Prepayment Provisions; Breakage Costs. The Borrowers shall
                    -------------------------------------
          have no right to voluntarily prepay any principal amount of any Loans
          other than Base Rate Loans. If the Borrowers repay any Offshore Rate
          Loan prior to the last day of the applicable Interest Period for any
          reason, such Borrower or Borrowers shall pay to the Lender the amount
          of any cost, loss (including loss of anticipated profits) or expense
          incurred by the Lender as a result of the repayment of an Offshore
          Rate Loan prior to the last day of the Interest Period applicable to
          such Loan including, without limitation, any cost or expense incurred
          by Lender by reason of the liquidation and reemployment of deposits or
          other funds acquired by the Lender to fund the Offshore Rate Loan.

               2.9  Increased Costs; Increased Capital. In the event that the
                    ----------------------------------
          Lender determines that compliance with any United States or Canadian
          (including any state, political subdivision, provincial, territory or
          possession thereof) or other foreign law, regulation, treaty,
          directive or guideline, currently or hereafter in effect, or the
          interpretation or application thereof, or the compliance with any
          request, guideline or directive (whether or not having the force of
          law) from any United States, Canadian or foreign central bank or any
          other Governmental Authority:

                    (a)  imposes, modifies or holds applicable any reserve,
               special deposit, compulsory loan or similar requirement against,
               or imposes any other conditions with respect to assets held by,
               or deposits or other liabilities in or for the account of,
               advances or loans by, or other credit or commitment therefor
               extended by, or any other acquisition of funds by, any office of
               the Lender which is not otherwise included or accounted for in
               any determination of the Eurodollar Rate or CDOR Rate or any
               interest payable hereunder; or

                    (b)  affects or would affect the amount of capital required
               or expected to be maintained by the Lender or any corporation
               controlling the Lender and the 

                                      -33-
<PAGE>
 
               Lender determines that the amount of such capital is increased by
               or based upon the existence of the Lender's obligations to make,
               maintain or fund the Offshore Rate Loans;

          and the result is to increase (as reasonably determined by the Lender)
          the cost to the Lender of (i) agreeing to make, making, funding,
          renewing or maintaining the Offshore Rate Loans hereunder, or (ii)
          agreeing to maintain, or its maintenance of, the Working Capital
          Commitment hereunder, or to reduce any amount receivable in respect of
          any of the foregoing, or to reduce (as determined by the Lender) the
          rate of return on the Lender's or such controlling corporation's
          capital (taking into account the policies of the Lender or corporation
          with regard to capital), then, in any such case, the U.S. Borrowers
          and SLQ agree to pay, on account of the Loans for which they are
          liable, to the Lender upon the Lender's demand any additional amount
          as may be necessary to compensate fully the Lender for such additional
          cost, reduced amount receivable, or reduced rate of return as
          reasonably deter mined by the Lender to place the Lender in the same
          economic position as if such compliance had not occurred. The Lender
          will promptly notify the Borrowers, in writing, of the occurrence of
          any of the events described in this Section 2.9.

               2.10 Payments and Computations.
                    -------------------------

                    (a)  All payments of principal, interest, Reimbursement
               Obligations and fees hereunder and under the Notes payable to the
               Lender shall be made without condition or reservation of right
               and in same day funds in the same currency as the currency in
               which such amount is outstanding and delivered to the Lender not
               later than 1:00 p.m. (Chicago time) on the date due to such
               account of the Lender as the Lender may designate; and funds
               received by the Lender after that time shall be deemed to have
               been paid on the next succeeding Business Day.

                    (b)  Each of the Borrowers hereby authorizes the Lender and,
               unless the Borrowers have arranged for another means of payment
               satisfactory to the Lender, the Lender shall, if and to the
               extent any payment is due by such Borrower hereunder, to charge
               from time to time against any or all of such Borrower's accounts
               with the Lender any amount so due from such Borrower(s). The
               Lender shall notify the Borrowers of any such charge; provided,
               however, that the failure to give such notice shall not limit or
               otherwise affect the obligation of the Borrowers to make any
               payment when due hereunder.

                    (c)  All computations of interest calculated on the basis of
               the Base Rate shall be made by the Lender on the basis of a year
               of 365 or 366 days as applicable, and all calculations of all
               other interest and fees shall be calculated on the basis of a
               year of 360 days, in each case, for the actual number of days
               (including the first day but excluding the last day) occurring in
               the period for which such interest or fees are payable. Each
               determination by the Lender of an interest rate hereunder shall
               be conclusive and binding for all purposes, absent 

                                      -34-

               manifest error. For the purposes of the Interest Act (Canada) and
               disclosure thereunder, whenever interest to be paid hereunder is
               to be calculated on the basis of a year of 360 days or any other
               period of time that is less than a calendar year, the yearly rate
               of interest to which the rate determined pursuant to such
               calculation is equivalent is the rate so determined multiplied by
               the actual number of days in the calendar year in which the same
               is to be ascertained and divided by either 360 or such other
               period of time, as the case may be.

                    (d)  Whenever any payment hereunder shall be stated to be
               due on a day other than a Business Day, such payment shall be
               made on the next succeeding Business Day, and such extension of
               time shall in such case be included in the computation of payment
               of interest or the Non-Use Fee, as the case may be; provided,
                                                                   --------
               however, if such extension would cause payment of interest on or
               -------
               principal of Offshore Rate Loans to be made in the next following
               calendar month, such payment shall be made on the next preceding
               Business Day.
     
                    (e)  Prior to the occurrence of an Event of Default, except
               as otherwise directed by the U.S. Borrowers or SLQ (and
               notwithstanding any other application thereof by the Lender on
               its books, which application may be made in the Lender's
               discretion), any payments received by the Lender from the U.S.
               Borrowers shall be applied as follows: first, to pay interest due
                                                      ----- 
               in respect of Working Capital Loans; second, to pay interest due
                                                    ------   
               in respect of the B Term Loan and the A Term Loan (in that
               order); third, to pay the outstanding principal of the Working
                       ----- 
               Capital Loans which constitute Base Rate Loans; fourth, to pay
                                                               ------
               the outstanding principal of the Working Capital Loans which
               constitute Offshore Rate Loans (in the order of their maturity);
               fifth, to pay the outstanding principal of any portion of the B
               -----
               Term Loan and the A Term Loan (in that order) which constitute
               Base Rate Loans; sixth, to pay the outstanding principal of any
                                -----
               portion of the B Term Loan and the A Term Loan (in that order)
               which constitute Offshore Rate Loans; seventh, to provide cash
                                                     -------  
               collateral in respect of Letter of Credit Obligations; and
               eighth, to the payment of any other Obligation due to the Lender.
               ------
               Any payments received from SLQ by the Lender, prior to an Event
               of Default, unless otherwise directed by SLQ shall be applied to
               the Canadian Term Loan, first to any accrued interest which is
               due, then to pay the outstanding principal amount in respect
               thereof in order of maturity. During the existence of an Event of
               Default, the Lender may apply any payments received by the
               Borrowers to the Obligations for which they are liable in any
               manner determined by the Lender in its discretion. No checks,
               drafts or other instruments received by the Lender shall
               constitute final payment to the Lender for the accounts of the
               Lender unless and until such item or payment has actually been
               collected. All items or amounts which are delivered to the Lender
               by or on behalf of any Borrower or any Account Debtor on account
               of partial or full payment or otherwise as proceeds of any of the
               Properties of such Borrower or Third Party Collateral (including
               any items or amounts which may have been deposited to the U.S.
               Borrower Concentration Account or the SLQ Concentration Account)
               may,

               the Lender's discretion, be released to the Borrowers or may be
               applied by the Lender towards payment of the Obligations for
               which such Borrower is liable, whether or not then due as
               provided in the foregoing terms of this subsection.
               Notwithstanding anything to the contrary herein, (i) solely for
               purposes of determining the occurrence of an Event of Default,
               all cash, checks, instruments and other items of payment shall be
               deemed received upon actual receipt by the Lender, unless the
               same is subsequently dishonored for any reason whatsoever, (ii)
               for purposes of determining whether, under Sections 2.4 and 3.2,
                                                          ------------     ---  
               there is availability for Working Capital Loans or Letters of
               Credit and for purposes of interest calculation hereunder, (A)
               all cash and collected funds shall be deemed to have been applied
               against the Obligations on the Business Day which Lender shall
               have received, prior to 1:00 p.m. (Chicago time), such funds, and
               (B) all checks, instruments and other items of payment shall be
               deemed to have been applied against the Obligations on the second
               (2nd) Business Day after the Business Day on which the Lender
               shall have received, prior to 1:00 p.m. (Chicago time), such
               items of payment. The foregoing apportionment of payments is
               solely for the purpose of determining the obligations of the
               Borrowers hereunder and, notwithstanding such apportionment,
               Lender may on its books and records allocate payments received by
               it in a manner different from that contemplated hereby. No such
               different allocation shall alter the rights and obligations of
               the Borrowers under this Agreement determined in accordance with
               the apportionments contemplated by this subsection (e). To the
                                                       -------------- 
               extent that any of the Borrowers make a payment or payments to
               the Lender, including, without limitation, proceeds of the
               Accounts, other Properties of such Borrower or Third Party
               Collateral for the Borrowers' benefit, which payment(s) or
               proceeds or any part thereof are subsequently invalidated,
               declared to be fraudulent or preferential, set aside and/or
               required to be repaid to a trustee, receiver or any other party
               under any bankruptcy law, state or federal law, common law or
               equitable cause then, to the extent of such payment or proceeds
               received, the Obligations or part thereof intended to be
               satisfied shall be revived and continue in full force and effect,
               as if such payment or proceeds had not been received by the
               Lender.

                    (f)  Each Borrower hereby authorizes the Lender, and the
               Lender may, in its discretion, charge to each Borrower at any
               time when due all or any portion of any of the Obligations for
               which it is liable (and interest, if any, thereon), including but
               not limited to any costs and expenses of the Lender relating
               thereto for which such Borrower is liable pursuant to the terms
               of this Agreement or any other Loan Document, by charging Emons'
               Demand Deposit Account or any other bank account of any Borrower
               liable for such Obligation maintained with the Lender; provided,

               however, that the provisions of this subsection (f) shall not

               affect such Borrower's obligation to pay when due all amounts
               payable by such Borrower under this Agreement, or any other Loan
               Document, whether or not there are sufficient funds therefor in
               the Demand Deposit Account or any such other bank account of such
               Borrower.

               and without deduction for any and all present or future taxes,
               levies, imposts, deductions, charges or withholdings, and all
               liabilities with respect thereto, excluding taxes imposed on the
                                                 ---------
               Lender's income, and franchise taxes imposed on the Lender, by
               the jurisdiction under the laws of which the Lender is organized
               or any political subdivision thereof and excluding also any net
               income taxes imposed on the Lender as a result of its present or
               former connection with Canada or any province or any political
               subdivision thereof other than a connection arising from the
               Lender having executed, delivered or performed its obligations,
               received payment under or enforced this Agreement (all such
               nonexcluded taxes, levies, imposts, deductions, charges,
               withholdings and liabilities being hereinafter referred to as
               "Taxes"). If any of the Borrowers shall be required by law to
                -----
               deduct any Taxes from or in respect of any sum payable hereunder
               to the Lender, (i) the sum payable shall be increased as may be
               necessary so that after making all required deductions (including
               deductions applicable to additional sums payable under this
               Section 2.11) the Lender receives an amount equal to the sum it
               ------------
               would have received had no such deductions been made, (ii) such
               Borrower shall make such deductions with respect to Obligations
               for which they are liable and (iii) such Borrower shall pay the
               full amount so deducted to the relevant taxing authority or other
               appropriate authority in accordance with applicable law.


                    (b)  In addition, each Borrower agrees to pay any present or
               future stamp or documentary taxes or any other excise or property
               taxes, charges or similar levies which arise from any payment
               made hereunder or under the Notes for which such Borrower is
               liable or from the execution, delivery or registration of, or
               otherwise with respect to, this Agreement or the Notes for which
               such Borrower is liable (but specifically excluding, any taxes
               due as a result of any assignment or participation made by the
               Lender as permitted by the terms of Section 11.2 hereof)
               (hereinafter referred to as "Other Taxes").

                    (c)  The U.S. Borrowers, in respect of the U.S. Loan
               Repayment Obligations, and SLQ, in respect of the Canadian Term
               Loan Repayment Obligations, agree to indemnify the Lender for the
               full amount of Taxes or Other Taxes (including, without
               limitation, any Taxes or Other Taxes imposed by any jurisdiction
               on amounts payable under this Section 2.11) paid by the Lender
                                             ------------
               and any liability (including penalties, interest and expenses)
               arising therefrom or with respect thereto. Any amounts due from
               any of the U.S. Borrower or SLQ as the case may be in accordance

               Lender agrees that it shall not pay any Taxes or Other Taxes if
               it has received written notice from any Borrower that such

               perfected security interest in any of such Borrower's Property or
               any of the Lender's rights and remedies hereunder.

                    (d)  Within 30 days after the date of any payment of Taxes,
               the Borrower making such payment will furnish to the Lender, at
               its address referred to on the signature page hereto, the
               original or a certified copy of a receipt evidencing payment

               Lender's request therefor, and as to such Taxes and taxing
               authorities specifically designated in such request and
               respecting which no receipt is delivered by such Borrower, a
               certificate from each appropriate taxing authority or an opinion
               of counsel acceptable to the Lender, in either case, stating that
               such payment is exempt from or not subject to such Taxes.

                    (e)  Without prejudice to the survival of any other
               agreement of the Borrowers hereunder, the agreements and
               obligations of the Borrowers contained in this Section 2.11 shall

                    --------------
          Emons on behalf of the Borrowers, giving effect to reserves

          set forth in a Borrowing Base Certificate delivered to the Lender by
          Emons on behalf of the Borrowers in accordance with Section 5.2(i) and
                                                              --------------   
          Article VIII. The Lender shall have the right to review, confirm and

          values ascribed by the U.S. Borrowers and SLQ to Eligible Receivables,
          and the reserves therefor, in any Borrowing Base Certificate, such
          adjustments to include, without limitation, reductions for such
          reserves as the Lender deems proper and reasonable.

                    ---------------------                                      
          or extending any Letter of Credit, the U.S. Borrowers shall pay to the
          Lender a fee (the "L/C Fee") in an amount equal to the Applicable
                             -------                                       
          Margin for Letters of Credit multiplied by the face amount of the

          extended and then multiplied by a fraction, the numerator of which is
          the number of days from the issue date (or extension date) of such
          Letter of Credit through but not including the expiry date (or new
          expiry date) of such Letter of Credit and the denominator of which
          shall be 365. In addition, if any Letter of Credit has a period longer
          than one (1) year or if any Letter of Credit is renewed so that it
          does not expire until after the first anniversary of its issuance, the
          U.S. Borrowers shall pay to the Lender on each anniversary of the date
          such Letter of Credit is issued until such Letter of Credit expires or
          is terminated, an amount equal to (i) the Applicable Margin for
          Letters of Credit multiplied by (ii) the face amount of such Letter of
                            -------------
          Credit then outstanding, multiplied by (ii) a fraction, the numerator
                                   -------------
          of which shall be the number of days in the in the succeeding twelve
          (12) month period prior to the stated expiration date of such Letter
          of Credit, and the denominator of which shall be 365.

               (b)  Increased Capital.  If either (i) the introduction of or any
                    -----------------                                           
          change in or in the interpretation of any law or regulation or (ii)
          compliance by the Lender with any guideline or request from any
          central bank or other Governmental Authority (whether or not having
          the force of law) affects or would affect the amount of capital
          required or expected to be maintained by it or any corporation
          controlling it and the Lender determines, on the basis of reasonable
          allocations, that the amount of such capital is increased by or is
          based upon its issuance or maintenance of, or commitment to issue, the
          Letters of Credit then, upon demand by the Lender, the U.S. Borrowers
          shall immediately pay to Lender, from time to time as specified by the
          Lender, additional amounts sufficient to compensate the Lender
          therefor. A certificate as to such amounts submitted to the U.S.
          Borrowers by the Lender shall, in the absence of manifest error, be
          conclusive and binding for all purposes.

          agree to protect, indemnify, pay and save the Lender harmless from and
          against any and all claims, demands, liabilities, damages, losses,
          costs, charges and expenses (including reasonable attorneys' fees)
          which the Lender may incur or be subject to as a consequence, direct
          or indirect, of (i) the issuance of any Letter of Credit other than as
          a result of the Lender's recklessness or willful misconduct, as
          determined by a court of competent jurisdiction or (ii) the failure of
          the Lender to honor a drawing under a Letter of Credit as a result of
          any act or omission, whether rightful or wrongful, of any present or
          future de jure or de facto Governmental Authority (all such acts or
          omissions herein called "Government Acts").

          negligence or willful misconduct of the Lender: (i) for the form,
          validity, sufficiency, accuracy, genuineness or legal effect of any
          document submitted by any party in connection with the application for

          to be in any or all respects invalid, insufficient, inaccurate,
          fraudulent or forged; (ii) for the validity or sufficiency of any
          instrument transferring or assigning or purporting to transfer or
          assign a Letter of Credit or the rights or benefits thereunder or
          proceeds thereof, in whole or in part, which may prove to be invalid
          or ineffective for any reason; (iii) for failure of the beneficiary of
          a Letter of Credit to comply duly with conditions required in order to
          draw upon such Letter of Credit; (iv) for errors, omissions,
          interruptions or delays in transmission or delivery of any messages,
          by mail, cable, telegraph, telex or otherwise, whether or not they be
          in cipher; (v) for errors in interpretation of technical terms; (vi)
          for any loss or delay in the transmission or otherwise of any document
          required in order to make a drawing under any Letter of Credit or of
          the proceeds thereof; (vii) for the misapplication by the beneficiary
          of a Letter of Credit of the proceeds of any drawing under such Letter
          of Credit; and (viii) for any consequences arising from causes beyond
          the control of the Lender including, without limitation, any
          Government Acts. None of the above shall affect, impair, or prevent
          the vesting of any of the Lender's rights or powers under this Section
                                                                         -------

          limitation of the specific provisions hereinabove set forth, any
          action taken or omitted by the Lender under or in connection with the
          Letters of Credit or any related certificates, if taken or omitted in
          Good Faith, shall not put the Lender under any resulting liability to
          the U.S. Borrowers or relieve the U.S. Borrowers of any of their
          obligations hereunder to any such Person.

               limitation, any sums at any time on deposit in any Collection
               Account or the U.S. Borrower Concentration Account), provided,

     from time to time hereafter to execute, deliver and/or cause to be recorded
     such mortgages, deeds of trust, leasehold mortgages, leasehold deeds of
     trust and other security documents reasonably requested 

                                      -45-

     by the Lender (collectively, the "Real Property Security Documents")
                                       --------------------------------
     relating to all of such Borrower's right, title and interest in all of
     those easements, rights-of-way, plots, pieces or parcels of land now or
     hereafter owned, leased or otherwise acquired by such Borrower, the
     improvements situated thereon and other rights relating thereto
     (collectively, the "Real Property"). The Real Property Security Documents
                         -------------
     shall be in form and substance reasonably satisfactory to the Lender and
     grant valid and perfected Liens on the Real Property to the Lender.

          4.3  Perfection and Protection of Security Interest.
               ---------------------------------------------- 

               (a)  The U.S. Borrowers shall, at their expense, perform all
          steps reasonably requested by the Lender at any time to perfect,
          maintain, protect, and enforce its Liens in the Collateral including,
          without limitation: (i) executing and filing financing or continuation
          statements, and amendments thereof, in form and substance satisfactory
          to the Lender; (ii) delivering to the Lender the original certificates
          of title for all motor vehicles of the U.S. Borrowers with the
          Lender's security interest properly endorsed thereon; (iii) delivering
          to the Lender the originals of all instruments, documents, and chattel
          paper, and all other Collateral of which the Lender determines it
          should have physical possession in order to perfect and protect the
          Lender's security interest therein, duly endorsed or assigned to the
          Lender without restriction; (iv) delivering to the Lender warehouse
          receipts covering any portion of the Collateral located in warehouses
          and for which warehouse receipts are issued; (v) delivering to the
          Lender all letters of credit on which any U.S. Borrower is named
          beneficiary; (vi) the filing and recordation with the U.S. Surface
          Transportation Board of this Agreement (or a memorandum thereof) and
          any other agreement under which any Person other than the Borrowers
          shall use any Rolling Stock; and (vii) taking such other steps as are
          deemed necessary by the Lender to maintain and protect its Liens. To
          the extent permitted by applicable law, the Lender may file, without
          any Borrower's signature, one or more financing statements disclosing
          its Liens. Each U.S. Borrower agrees that a carbon, photographic,
          photostatic, or other reproduction of this Agreement or of a financing
          statement is sufficient as a financing statement.

               (b)  If any Collateral is at any time in the possession or
          control of any warehouseman, bailee or any agent of any of the U.S.
          Borrowers, then such Borrower shall notify the Lender thereof and
          shall notify such Person of the Lender's security interest in such
          Collateral and, upon the Lender's request, instruct such Person to
          hold all such Collateral for the Lender's account subject to the
          Lender's instructions.  If at any time significant operations of any
          of the U.S. Borrower's business is operated on or any significant
          Collateral is located on any premises that are not owned by a U.S.
          Borrower, then such Borrower shall use Good Faith efforts to obtain,
          at the request of the Lender, attornment agreements in form and
          substance satisfactory to the Lender with the owner or lessor of such
          premises.

               (c)  From time to time, each U.S. Borrower shall, upon the
          Lender's request, execute and deliver confirmatory written instruments
          pledging to the Lender the Collateral, but any such Borrower's failure
          to do so shall not affect or limit the Lender's security interest or
          the Lender's other rights in and to the Collateral.  So long as the
          Working Capital Commitment is in effect or any of the Obligations
          remain outstanding, the Lender's Liens shall continue in full force
          and effect in all Collateral.

          4.4  Location of Properties.  Each Borrower represents and warrants to
               ----------------------                                           
     Lender that as of the date hereof:  (a) SCHEDULE 4.4 attached hereto and
                                             ------------                    
     incorporated herein by this reference is a correct and complete list of
     such Borrower's chief executive office, head of office, the location of its
     books and records, the locations of the Properties of such Borrower, and
     the locations of all of its other places of business; and (b) SCHEDULE 4.4
                                                                   ------------
     attached hereto correctly identifies any of such facilities and locations
     that are not owned by such Borrower and to the best of such Borrower's
     knowledge, sets forth the names of the owners and lessors or sublessors of
     such facilities and locations.  Such Borrower covenants and agrees that it
     will not maintain its Properties at any location other than those listed
     for it on SCHEDULE 4.4 attached hereto, and it will not otherwise change or
               ------------                                                     
     add to any of such locations, unless it gives the Lender at least five (5)
     days' prior written notice thereof and executes any and all financing
     statements and other documents that the Lender requests in connection
     therewith.

          4.5  Title to, Liens on, and Sale and Use of Properties.  Each
               --------------------------------------------------       
     Borrower represents and warrants to the Lender and agrees with the Lender
     that: (a) all the Properties of such Borrower are and will continue to be
     owned by such Borrower (whether by fee, leasehold, easement, right-of-way
     or otherwise) free and clear of all Liens whatsoever, except for Permitted
     Liens; (b) the Lender's Liens on the Properties of such Borrower will not
     be subject to any Lien which is prior in right of prepayment, other than
     the obligations to pay taxes with respect to real property (which taxes
     shall be paid when due); (c) such Borrower will use, store, and maintain
     its Properties with all reasonable care and will use its Properties for
     lawful purposes only; (d) upon the Lender's request, Accounts for any

     Authority shall be duly assigned or hypothecated, as the case may be, to
     the Lender in full compliance with the Federal Assignment of Claims Act (31
     U.S.C.A. (S) 3727 et seq.) or similar statute, if applicable, and (e) such
     Borrower will not, without the Lender's prior written approval, sell, or
     dispose of or permit the sale or disposition of any of its Properties,
     except for sales of Inventory in the ordinary course of business, and
     Equipment as permitted by Section 4.9; provided, however, that Lender's
                               -----------
     approval of the sale of the non-essential real estate Properties of such
     Borrower shall not be unreasonably withheld or delayed, and provided that
     the Net Cash Proceeds thereof are prepaid, if required under Section
                                                                  -------
     2.6(b). The inclusion of proceeds in the Properties of such Borrower
     ------
     subject to the Liens of Lender shall not be deemed to constitute the
     Lender's consent to any sale or other disposition of such Properties except
     as expressly permitted herein.

          4.6  Access and Examination; Appraisals.  The Lender may at all
               ----------------------------------

     exists) have access to, examine, audit, make extracts from, copy and
     inspect each Borrower's records, files, and books of account and the
     Properties of such Borrower, and discuss such Borrower's affairs with such
     Borrower's officers and management.  Each Borrower will deliver to the
     Lender any instrument necessary for the Lender to obtain records from any
     service bureau maintaining records for such Borrower.  Whenever a Default
     or Event of Default exists, such Borrower shall, at its expense and upon
     the Lender's request, provide the Lender with appraisals or updates thereof
     of any or all of the Properties of such Borrower from an appraiser, and
     prepared on a basis satisfactory to the Lender.

     the Collection Accounts described on Schedule 4.8 under arrangements
                                          ------------                   
     established by the Borrowers and acceptable to the Lender.  The Collection
     Accounts shall be maintained on terms acceptable to the Lender, subject to
     agreements in substantially the form attached hereto and made a part hereof
     as EXHIBIT H ("Collection Account Agreements") among the applicable
        ---------   -----------------------------                       
     Borrower, the Lender and the applicable financial institution at which such

     remit all amounts deposited in the applicable Collection Account, on a
     daily basis or as the Lender may direct to either the U.S. Borrower
     Concentration Account in the case of collections of the U.S. Borrowers, or
     the SLQ Concentration Account in the case of collections of SLQ, as the
     case may be. At all times during the term of this Agreement and
     notwithstanding the termination of this Agreement, until all of the
     Obligations shall have been fully paid and satisfied, each Borrower shall
     continue to deposit, or cause to be deposited, directly into a Collection
     Account or the U.S. Borrower Concentration Account or the SLQ Concentration
     Account, as the case may be, all collections of Accounts and other proceeds
     of Properties of such Borrower; provided, however that Finance may maintain
                                     --------  -------
     an operating account with First Union Bank of Delaware in Wilmington,
     Delaware provided that the amount on deposit in such account at no time
              --------
     exceeds $15,000.

          4.9  Equipment.  Each Borrower represents and warrants to the Lender
               ---------                                                      
     and agrees with the Lender that all of the Equipment owned or leased by
     such Borrower is and will be used or held for use in such Borrower's
     business (which includes the lease of such equipment to third parties from
     time to time), and is and will be fit for such purposes.  Each Borrower
     will use the Equipment in a careful and proper manner and will comply with
     and conform to all governmental laws, rules and regulations relating
     thereto.  Without limitation to the foregoing, each Borrower will (i) to
     the extent applicable to such Borrower, cause all Equipment to be used in
     compliance with all rules of AAR and FRA and (ii) will not permit any items
     of Equipment to be used outside the continental United States or Canada.
     Each Borrower shall keep and maintain its Equipment in good operating
     condition and repair (ordinary wear and tear excepted) and 

                                      -48-
<PAGE>
 
     shall make all necessary replacements thereof so that the condition and
     operating efficiency thereof will at all times be maintained and preserved,
     reasonable wear and tear excepted. Each Borrower will cause such item of
     Equipment which constitutes Rolling Stock to be maintained in conformance
     with all rules and regulations of AAR and FRA, to the extent applicable
     and, if mandated, modified so that it will qualify for unrestricted
     interchange in the United States or Canada and remain suitable for its
     intended use. Each Borrower shall promptly inform the Lender of any
     material additions to or deletions from the Equipment. No Borrower shall
     permit any Equipment to become a fixture to real property or an accession
     to other personal property, unless the Lender has a valid and perfected
     Lien in such real or personal property. Each Borrower will cause each item
     of Rolling Stock owned by such Borrower to be kept marked and numbered with
     the identifying mark and number set forth in SCHEDULE 4.9 hereto. No
                                                  ------------            
     Borrower will place or permit any such item of Rolling Stock to be placed
     in operation or exercise any control or dominion over the same until such
     number shall have been so marked on both sides thereof and will replace or
     cause to be replaced promptly any such name and words which may be removed,
     defaced, obliterated or destroyed. No Borrower will change or permit to be
     changed the identifying mark or number of any item of Rolling Stock unless
     and until a statement of new mark and/or number or numbers to be
     substituted therefor shall have been filed, recorded and deposited by such
     Borrower in all public offices where this Agreement shall have been filed,
     recorded and deposited. Except for occasional sales of Equipment, the
     proceeds of which represent the fair market value therefor and do not
     exceed $100,000 in the aggregate for all the Borrowers during any Fiscal
     Year, the Borrowers shall not, without the Lender's prior written consent,
     sell, lease as a lessor, or otherwise dispose of any of the Equipment.

          4.10 Contract Rights.  Each Borrower shall fully perform all of its
               ---------------                                               
     material obligations under each material contract to which it is a party
     and shall enforce all of its rights and remedies thereunder as it deems
     appropriate in its business judgment; provided, however, that such Borrower
                                           --------  -------                    
     shall not take any action or fail to take any action with respect to its
     Contract Rights which, in such Borrower's business judgment, exercised in
     Good Faith, would result in a waiver or other loss of any material right or
     remedy of such Borrower thereunder. Without limiting the generality of the
     foregoing, such Borrower shall take all action necessary or appropriate to
     permit, and shall not take any action which would have any material adverse
     effect upon, the full enforcement of all indemnification rights under its
     Contract Rights. Except in the ordinary course of business and consistent
     with past practices, no Borrower shall, without the Lender's prior written
     consent, modify, amend, supplement, compromise, satisfy, release, or
     discharge any of its Contract Rights, any collateral securing the same, any
     Person liable directly or indirectly with respect thereto, or any agreement
     relating to any of its Contract Rights or the collateral therefor. Each
     Borrower shall notify the Lender in writing, promptly after such Borrower
     becomes aware thereof, of any event or fact which could give rise to a
     claim by it for indemnification under any of its Contract Rights, and shall
     diligently pursue such right and report to the Lender on all further
     developments with respect thereto. If an Event of Default exists and the
     Borrowers have not cured or are unable to cure such Event of Default, then
     the Lender may directly enforce any material right

                                      -49-
<PAGE>
 
     in any Contract Rights of any of the Borrowers in its own or such
     Borrower's name and may enter into such settlements or other agreements
     with respect thereto as the Lender determines. In any suit, proceeding or
     action brought by the Lender under any Contract Rights for any sum owing
     thereunder or to enforce any provision thereof, each Borrower shall
     indemnify and hold the Lender harmless from and against all expense, loss
     or damage suffered by reason of any defense, setoff, counterclaims,
     recoupment, or reduction of liability whatsoever of the obligor thereunder
     arising out of a breach by any Borrower of any obligation thereunder or
     arising out of any other agreement, indebtedness or liability at any time
     owing from any Borrower to or in favor of such obligor or its successors.
     All such obligations of any Borrower shall be and remain enforceable only
     against such Borrower and shall not be enforceable against the Lender.
     Notwithstanding any provision hereof to the contrary, each of the Borrowers
     shall at all times remain liable to observe and perform all of its duties
     and obligations under its Contract Rights, and the Lender's exercise of any
     of its rights with respect to the Properties of each Borrower shall not
     release any Borrower from any of such duties and obligations. The Lender
     shall not be obligated to perform or fulfill any of a Borrower's duties or
     obligations under its Contract Rights or to make any payment thereunder, or
     to make any inquiry as to the nature or sufficiency of any payment or
     property received by it thereunder or the sufficiency of performance by any
     party thereunder, or to present or file any claim, or to take any action to
     collect or enforce any performance, any payment of any amounts, or any
     delivery of any property. Notwithstanding any provision in this Section
                                                                     -------
     4.10 to the contrary, provided no Event of Default has occurred and is
     ----
     continuing, the Lender shall not be permitted to waive or release on behalf
     of any Borrower any rights that any Borrower may have (whether at law or in
     equity) against any other party to its Contract Rights.

          4.11 Right to Cure.  The Lender may, in its discretion and at any time
               -------------                                                    
     after at least ten (10) days prior written notice, for any Borrower's
     account and at such Borrower's expense, pay any amount not being disputed
     by such Borrower in Good Faith or do any act required of such Borrower
     hereunder or reasonably requested by the Lender to preserve, protect,
     maintain or enforce the Obligations, the Properties of such Borrower or the
     Lender's Liens therein, and which such Borrower fails to pay or do,
     including, without limitation, payment of any judgment against such
     Borrower, any insurance premium, any warehouse charge, any landlord's
     claim, and any other Lien upon or with respect to the Properties of such
     Borrower. All payments that the Lender makes under this Section 4.11 and
                                                             ------------
     all out-of-pocket costs and expenses that the Lender pays or incurs in
     connection with any action taken by it hereunder shall be payable on
     demand. Any payment made or other action taken by the Lender under this
     Section 4.11 shall be without prejudice to any right to assert an Event of
     ------------
     Default hereunder and to proceed thereafter as herein provided.

          4.12 Power of Attorney.  Each Borrower hereby appoints the Lender and
               -----------------                                               
     the Lender's designees as such Borrower's attorney, with power to send
     requests for verification of accounts to customers or account debtors and
     after an Event of Default has occurred and as long as such Event of Default
     is continuing:  (a) to endorse such 

                                      -50-
<PAGE>
 
     Borrower's name on any checks, notes, acceptances, money orders, or other
     forms of payment or security that come into the Lender's possession; (b) to
     sign such Borrower's name on any invoice, bill of lading, or other document
     of title relating to any Properties of such Borrower, on drafts against
     customers, on assignments of Accounts, on notices of assignment, financing
     statements and other public records; (c) to notify the post office
     authorities to change the address for delivery of such Borrower's mail to
     an address designated by the Lender and to receive, open and dispose of all
     mail addressed to such Borrower; and (d) to do all things necessary to
     carry out this Agreement. Each Borrower ratifies and approves all acts of
     such attorney. Neither the Lender nor the attorney will be liable for any
     acts or omissions or for any error of judgment or mistake of fact or law
     except to the extent of the Lender's gross negligence or willful
     misconduct. This power, being coupled with an interest, is irrevocable
     until this Agreement has been terminated and the Obligations have been
     fully satisfied.

          4.13 The Lender's Rights, Duties and Liabilities.  Each Borrower
               -------------------------------------------                
     assumes all responsibility and liability arising from or relating to the
     use, sale or other disposition of the Properties of such Borrower except
     for liability resulting from the Lender's or any of its respective
     attorney's gross negligence or willful misconduct.  The Lender and its
     officers, directors, employees, and agents shall not be liable or
     responsible in any way for the safekeeping of any of the Properties of such
     Borrower except to the extent of the Lender's gross negligence or willful
     misconduct with respect thereto, or for any loss or damage thereto, or for
     any diminution in the value thereof, or for any act of default of any
     warehouseman, carrier, forwarding agency or other person whomsoever, all of
     which shall be at such Borrower's sole risk.  The Obligations shall not be
     affected by any failure of the Lender to take any steps to perfect its
     Liens or to collect or realize upon the Properties of such Borrower, nor
     shall loss of or damage to the Properties of such Borrower release any
     Borrower from any of the Obligations.  After the occurrence of and during
     the continuance of a Default or Event of Default, the Lender may (but shall
     not be required to), without notice to or consent from any of the
     Borrowers, sue upon or otherwise collect, extend the time for payment of,
     modify or amend the terms of, compromise or settle for cash, credit, or
     otherwise upon any terms, grant other indulgences, extensions, renewals,
     compositions, or releases, and take or omit to take any other action with
     respect to the Properties of such Borrower, any security therefor, any
     agreement relating thereto, any insurance applicable thereto, or any Person
     liable directly or indirectly in connection with any of the foregoing,
     without discharging or otherwise affecting the liability of such Borrower
     for the Obligations or under this Agreement or any other agreement now or
     hereafter existing between the Lender and such Borrower.

          4.14 The Guaranty.  Subject to Section 4.14(f) hereof, each of the

     Borrowers hereby unconditionally guarantees the full and punctual payment
     when due (whether at stated maturity, upon acceleration or otherwise) of
     the Canadian Term Loan Repayment Obligations (the obligations of each of
     the U.S. Borrowers under this Section 4.14 referred to in this Loan
                                   ------------
     Agreement as the "Guaranty"). Upon failure by SLQ to pay punctually when
     due any of the Canadian Term Loan Repayment Obligations, each of the U.S.
     Borrowers agrees that it shall forthwith on demand pay the amount not so
     paid at the place and in the manner specified in the relevant Loan
     Document, as the case may be. This Guaranty is a guaranty of payment and
     not of collection. The U.S. Borrowers shall be jointly and severally liable
     for the Canadian Term Loan Repayment Obligations under this Guaranty.

               (a)  Guaranty Unconditional.  Subject to Section 4.14(f) and

          hereunder shall be unconditional and absolute and, without limiting
          the generality of the foregoing, shall not be released, discharged or
          otherwise affected by any of the following, whether occurring before
          or after receipt by the Lender of notice of termination of this
          Guaranty:

                    (i)   any extension, renewal, settlement, compromise, waiver
               or release in respect of any obligation of SLQ under any of the
               Loan Documents, by operation of law or otherwise or any
               obligation of any other guarantor of any of the Canadian Term
               Loan Repayment Obligations;

                    (ii)  any modification or amendment of or supplement to any
               other Loan Document;

                    (iii) any release, nonperfection or invalidity of any direct
               or indirect security for any obligation of SLQ under any Loan
               Document, or any obligations of any other guarantor of any of the
               Canadian Term Loan Repayment Obligations;

                    (iv)  any change in the corporate existence, structure or
               ownership of SLQ or any other guarantor of any of the Canadian
               Term Loan Repayment Obligations, or any insolvency, bankruptcy,
               reorganization or other similar proceeding affecting SLQ, or any
               other guarantor of the Canadian Term Loan Repayment Obligations,
               or its assets or any resulting release or discharge of any
               obligation of SLQ, or any other guarantor of any of the Canadian
               Term Loan Repayment Obligations;

                    (v)   the existence of any claim, setoff or other rights
               which the U.S. Borrowers may have at any time against SLQ, any
               other guarantor of any of the Canadian Term Loan Repayment
               Obligations, the Lender or 

                                      -52-

               transactions;

                    (vi)   any invalidity or unenforceability relating to or
               against SLQ, or any other guarantor of any of the Canadian Term
               Loan Repayment Obligations, for any reason related to the Loan
               Documents or any provision of applicable law or regulation
               purporting to prohibit the payment by SLQ, or any other guarantor
               of the Canadian Term Loan Repayment Obligations, of the principal
               of or interest or any other amount payable by SLQ under the Loan
               Documents;

                    (vii)  any failure or omission to enforce any right, power
               or remedy with respect to the Canadian Term Loan Repayment
               Obligations or any part thereof or any agreement relating
               thereto, or any collateral securing the Canadian Term Loan
               Repayment Obligations or any part thereof;

                    (viii) any failure or omission to enforce any right, power
               or remedy with respect to the Canadian Term Loan Repayment
               Obligations or any part thereof or any agreement relating
               thereto, or any collateral securing the Canadian Term Loan
               Repayment Obligations or any part thereof;

                    (ix)   the application of payments received from any source
               to the payment of indebtedness other than the Canadian Term Loan
               Repayment Obligations, any part thereof or amounts which are not
               covered by this Guaranty even though the Lender might lawfully
               have elected to apply such payments to any part or all of the
               Canadian Term Loan Repayment Obligations or to amounts which are
               not covered by this Guaranty; or

                    (x)    any other act or omission to act or delay of any kind
               by SLQ, any other guarantor of the Canadian Term Loan Repayment
               Obligations, the Lender, or any other person or any other
               circumstance whatsoever which might, but for the provisions of
               this paragraph, constitute a legal or equitable discharge of any
               U.S. Borrower's obligations hereunder.

               (b)  Discharge Only Upon Payment In Full: Reinstatement In
                    -----------------------------------------------------
          Certain Circumstances.  The obligations of each of the U.S. Borrowers
          ---------------------                                                
          hereunder shall remain in full force and effect until all Canadian
          Term Loan Repayment Obligations shall have been paid in full. If at
          any time any payment of the principal of or interest or any other
          amount payable by SLQ or any other party on account of the Canadian
          Term Loan Repayment Obligations is rescinded or must be otherwise
          restored or returned upon the insolvency, bankruptcy or reorganization
          of SLQ or otherwise, the obligations of each of the U.S.

                                      -53-
<PAGE>
 
          Borrowers hereunder with respect to such payment shall be reinstated
          as though such payment had been due but not made at such time.

               (c)  Waivers.  Each of the U.S. Borrowers irrevocably waives
                    -------                                                
          notice of acceptance hereof, presentment, demand, protest, the benefit
          of any statutes of limitations and, to the fullest extent permitted by
          law, any notice not provided for herein, as well as any requirement
          that at any time any action be taken by any person against SLQ, any
          other guarantor of the Canadian Term Loan Repayment Obligations, any
          other person or any collateral securing the Canadian Term Loan
          Repayment Obligations.

               (d)  Subrogation.  Each of the U.S. Borrowers hereby waives and
                    -----------                                               
          agrees not to assert any right, claim or cause of action, including,
          without limitation, a claim for subrogation, reimbursement,
          indemnification or otherwise, against SLQ arising out of or by reason
          of this Guaranty or the obligations hereunder, including, without
          limitation, the payment or securing or purchasing of any of the
          Canadian Term Loan Repayment Obligations by any of the U.S. Borrowers
          unless and until the Canadian Term Loan Repayment Obligations are paid
          in full.

               (e)  Stay of Acceleration.  If acceleration of the time for
                    --------------------                                  
          payment of any amount payable by SLQ under any of the Loan Documents
          is stayed upon the insolvency, bankruptcy or reorganization of SLQ,
          all such amounts otherwise subject to acceleration under the terms of
          the Loan Documents shall nonetheless be payable by each of the U.S.
          Borrowers hereunder forthwith on demand by the Lender.

               (f)  Limitation on Canadian Term Loan Repayment Obligations.
                    ------------------------------------------------------ 

                    (i) It is the intention of each of the U.S. Borrowers and
               the Lender that each U.S. Borrower's obligations under this
               Guaranty shall be, but not in excess of, as of any date, the
               greater of the following (such greater amount determined
               hereunder being the relevant U.S. Borrower's "Maximum
               Liability"): (i) the aggregate amount of all monies received by
               the U.S. Borrower from SLQ during the term of this Agreement
               (whether by loan, capital infusion or other means other than by
               way of repayment of the SLQ Intercompany Obligations), or (ii)
               the maximum amount (such amount being the U.S. Borrower's
               "Alternative Limitation") not subject (but for the provisions of
               this Section 4.14(f)) to avoidance under the Bankruptcy Code.  To

               Borrower, only to the extent such obligations would otherwise be
               subject to avoidance under the Bankruptcy Code if such U.S.
               Borrower is not deemed to have received valuable consideration,
               fair value or reasonably equivalent value for its obligations

               which, after giving effect thereto, would not render such U.S.
               Borrower insolvent, or leave such U.S. Borrower with an
               unreasonably small capital to conduct its business, or cause such
               U.S. Borrower to have incurred debts (or intended to have
               incurred debts) beyond its ability to pay such debts as they
               mature, at the time such obligations are deemed to have been
               incurred under the Bankruptcy Code. As used herein, the terms
               "insolvent" and "unreasonably small capital" shall likewise be
               determined in accordance with the Bankruptcy Code. This Section
                                                                       -------

               -------
               Borrower is intended solely to preserve the rights of the Lender
               hereunder to the maximum extent not subject to avoidance under
               the Bankruptcy Code, and none of the U.S. Borrowers nor any other
               person or entity shall have any right or claim under this Section
                                                                         -------

               -------
               extent necessary so that the obligations of the U.S. Borrowers
               hereunder shall not be rendered voidable under the Bankruptcy
               Code.

                    (ii)  Each of the U.S. Borrowers agrees that the Canadian
               Term Loan Repayment Obligations may at any time and from time to
               time exceed the Maximum Liability of each U.S. Borrower, and may
               exceed the aggregate Maximum Liability of the other U.S.
               Borrowers, without impairing this Guaranty or affecting the
               rights and remedies of the Lender hereunder.  Nothing in this
               Section 4.14(f) shall be construed to increase any U.S.

               Borrower's obligations hereunder beyond its Maximum Liability.

                    (iii) Nothing in this Section 4.14(f) shall affect any U.S.
                                           ---------------                      
               Borrower's joint and several liability for the entire amount of
               the Canadian Term Loan Repayment Obligations (up to such U.S.
               Borrower's Maximum Liability).  Each of the U.S. Borrowers
               covenants and agrees that its right to receive any contribution
               under this Guaranty from any  non-paying U.S. Borrower shall be
               subordinate and junior in right of payment to all the Canadian
               Term Loan Repayment Obligations.

               (g)  Right of Setoff.  Without limiting the rights of the Lender
                    ---------------                                            
          under applicable law, each U.S. Borrower authorizes the Lender to
          apply or offset any sums standing to the credit of such U.S. Borrower
          with any office, branch, subsidiary or affiliate of the Lender to the
          payment when due of any amount owing by the U.S. Borrowers under this
          Guaranty.

         any law, statute, regulation, ordinance, judgment, order, or decree
         applicable to it which violation would in any respect materially and
         adversely affect the Properties of such Borrower, the repayment of the
         Obligations, the Lender's rights under the Loan Documents, or such
         Borrower's Property, business, operations, or condition (financial or
         otherwise), taken as a whole.

               6.17 No Default.  Such Borrower is not in default with respect
                    ----------
         to any note, indenture, loan agreement, mortgage, lease, deed, or other
         agreement to which such Borrower is a party or by which it is bound,
         which default would materially and adversely affect the Properties of
         such Borrower, the repayment of the Obligations, any Lender's rights
         under the Loan Documents, or such Borrower's Property, business,
         operations, or condition (financial or otherwise), taken as a whole.

                    ----- 

                    (a)  Neither such Borrower nor any of its ERISA Affiliates
               has or contributes to any Plan other than those listed on
               SCHEDULE 6.18 attached hereto and incorporated herein by this
               -------------
               reference.

                    (b)  Except as provided on SCHEDULE 6.18 attached hereto,
                                               -------------
               none of such Borrower's Benefit Plans has been terminated or
               partially terminated or is insolvent or in reorganization, nor
               have any proceedings been instituted to terminate or reorganize
               any Plan.

                    (c)  Neither such Borrower nor any of its ERISA Affiliates
               has withdrawn from any Multiemployer Plan in a complete or
               partial withdrawal, nor has a condition occurred which if
               continued would result in a complete or partial withdrawal.

                    (d)  Neither such Borrower nor any of its ERISA Affiliates
               has incurred any withdrawal liability, including contingent
               withdrawal liability, to any Benefit Plan pursuant to Title IV of
               ERISA as of December 31, 1997.

                    (e)  Neither such Borrower nor any of its ERISA Affiliate
               has any liability to the PBGC other than for required insurance
               premiums which have been paid when due.

                    (f)  No Reportable Event has occurred with respect to a
               Benefit Plan.

                    (g)  No Benefit Plan has an "accumulated funding deficiency"
               (whether or not waived) as defined in Section 302 of ERISA or in
               Section 412 of the Code.

                    (h)  Except as provided on SCHEDULE 6.18 attached hereto, to
                                               -------------
               the best of such Borrower's knowledge each Plan is in substantial
               compliance with ERISA, and neither any Borrower nor any of its
               ERISA Affiliates has received any notice asserting that a Plan is
               not in compliance with ERISA.

                    (i)  Except as provided on SCHEDULE 6.18 attached hereto,
                                               -------------
               each Plan which is intended to be a qualified Plan has been
               determined by the IRS to be qualified under Section 401(a) of the
               Code as currently in effect and neither such Borrower nor any of
               its ERISA Affiliates knows or has reason to know why each such
               plan should not continue to be so qualified, and each trust
               related to such Plan has been determined to be exempt from
               federal income tax under Section 501(a) of the Code.

                    (j)  Except as provided on SCHEDULE 6.18 attached hereto,
                                               -------------
               neither such Borrower nor any of its ERISA Affiliates maintains
               or contributes to any employer welfare benefit plan within the
               meaning of Section 3(1) of ERISA which provides lifetime benefits
               to retirees.

                    (k)  Neither such Borrower nor any of its ERISA Affiliates
               has failed to make a required installment under subsection (m) of
               Section 412 of the Code or any other payment required under
               Section 412 of the Code on or before the due date for such
               installment or other payment.

                    (l)  Neither such Borrower nor any of its ERISA Affiliates
               is required to provide security to a Benefit Plan under Section
               401(a)(29) of the Code due to a Plan amendment that results in an
               increase in current liability for the plan year.

                    (m)  To the best of Borrower's knowledge, neither such
               Borrower, nor any of its ERISA Affiliates, nor any other "party-
               in-interest" or "disqualified person" has engaged in a
               "prohibited transaction," as such terms are defined in Section
               4975 of the Code and Section 406 of ERISA, in connection with any
               Plan or any other employee benefit plan to which the Borrower or
               any of its ERISA Affiliates is, or within the immediately
               preceding six (6) years was, an "employer" as defined in Section
               3(5) of ERISA or has taken or failed to take any action which
               would constitute or result in a Termination Event.

                    (n)  To the best of Borrower's knowledge, neither such
               Borrower nor any of its ERISA Affiliates has failed to comply
               with the health care continuation coverage requirements of
               Section 4980B of the Code in respect of employees and former
               employees of such Borrower or such ERISA Affiliate and their
               dependant and beneficiaries which alone or in the aggregate would
               subject such Borrower or such ERISA Affiliate to any material
               liability.

                    (o)  To the best knowledge of such Borrower or any of its
               ERISA Affiliates after due inquiry, the consummation of the
               transactions contemplated by the Acquisition shall not result in
               any liability to any Borrower or any ERISA Affiliates under any
               employment-related agreement, contract or arrangement, whether
               written or oral, including without limitation, any severance pay
               agreement. The liability of any Borrower or any of its ERISA
               Affiliates to make payments to any employee on account of
               termination of employment under individual employment or
               severance agreements does not in the aggregate give rise to any
               material liability to the Borrower or such ERISA Affiliate.

               6.19 Taxes. Except as set forth on SCHEDULE 6.19, such Borrower
                    -----                         ------------- 
         has filed all tax returns and other reports which it was required by
         law to file on or prior to the date hereof and has paid all taxes
         assessments, fees, and other governmental charges, and penalties and
         interest, if any, against it or its Property, income, or franchise,
         that are due and payable except where the failure to do so could not,
         individually or in the aggregate, have a material adverse effect on the
         business, operations, properties, assets or condition (financial or
         otherwise) of such Borrower.

               6.20 Investment Act. Such Borrower is not an "investment company"
                    --------------  
         nor an "affiliated person" of, or "promoter" or "principal underwriter"
         for, an "investment company," as such terms are defined in the
         Investment Company Act of 1940, as amended (15 U.S.C. ss. 80(a)(l), et
         seq.). The making of Loans under the A Term Loan Facility, the B Term
         Loan Facility, the Canadian Term Loan Facility or the Working Capital
         Facility, and other financial accommodations hereunder by the Lender,
         the application of the proceeds and repayment thereof by the Borrowers
         and the consummation of the other transactions contemplated by this
         Agreement and the Loan Documents do not violate any provisions of such
         Act or any rule, regulation or order issued by the Securities and
         Exchange Commission thereunder.

               6.21 Margin Securities. Such Borrower does not own any "margin
                    -----------------  
         security" (as that term is defined in Regulations U and X) and the
         proceeds of Loans under the A Term Loan Facility, the B Term Loan
         Facility, the Canadian Term Loan Facility and the Working Capital
         Facility, and the other financial accommodations made pursuant to this
         Agreement will be used only for the purposes contemplated hereunder.
         None of the transactions contemplated by this Agreement, or the Loan
         Documents will violate Regulations U or X. None of the Loans under the
         A Term Loan Facility, the B Term Loan Facility, the Canadian Term Loan
         Facility or the Working Capital Facility or the other financial
         accommodations hereunder have been or will be used, directly or

                                      -67-
<PAGE>
 
         indirectly, for the purpose of purchasing or carrying any margin
         security, for the purpose of reducing or retiring any Debt or other
         Person's indebtedness which was originally incurred to purchase or
         carry any margin security, or for any other purpose which might cause
         any such loan or other financial accommodation to be considered a
         "purpose credit" within the meaning of Regulation U or X. Such Borrower
         will neither take nor permit any agent acting on its behalf to take any
         action which might cause any transaction, obligation or right created
         by this Agreement, or any document or instrument delivered pursuant
         hereto, to violate any regulation of the Federal Reserve Board.

               6.22 Benefit. Each of the Borrowers will benefit, directly or
                    ------- 
         indirectly, from the Credit Facilities as a result of the synergistic
         operations of their respective businesses.

               6.23 Industries Corporate Separateness. Since August 1, 1992, and
                    ---------------------------------
         to the best knowledge of such Borrower prior to that date, there have
         been no transfers of property or property rights (including money) by
         Industries to, or to Industries by, any of the other Borrowers without
         adequate consideration and the observance of "corporate formalities"
         other than the distribution by Industries of dividends to Emons in
         accordance with applicable corporate law and, after giving effect
         thereto, Industries retained sufficient capital for its operations and
         to pay known liabilities. "Corporate formalities" as used herein, with
         respect to any transaction, includes the adoption of appropriate
         authorizing resolutions, evidencing such transaction by customary
         documentation, executed and delivered by duly authorized officers, and
         compliance with the terms and conditions set forth in such
         documentation. Industries has not and does not commingle its assets,
         liabilities or business functions with those of the other Borrowers.
         Industries has at all times maintained separate accounting and
         corporate records and has had regular board of director meetings and
         shareholder meetings as contemplated by its Articles of Incorporation
         and By-laws. Industries now holds (and has held at all times) itself
         out as a separate corporation and not as a division of any other
         Borrower, nor has Industries represented or conducted its affairs at
         any time in a manner which would cause other Persons to believe that
         any other Borrower is part of or a division of Industries. Industries
         maintains bank accounts separate and apart from the other Borrowers and
         is billed for and pays its own expenses or pays its pro rata share of
         common expenses on a fair and equitable allocation basis. To the extent
         Industries is included in the consolidated financial statements of
         Emons and the other Borrowers, the existence and ownership of
         Industries has been adequately disclosed in footnotes.

               6.24 Disclosure. Neither this Agreement nor any document or
                    ----------    
         statement furnished to the Lender by or on behalf of any Borrower or in
         contemplation of this Agreement or in connection herewith contains any
         untrue statement of a material fact or omits to state any material fact
         necessary in order to make the statements contained herein or therein
         not materially misleading.

                                 ARTICLE VII.
                      AFFIRMATIVE AND NEGATIVE COVENANTS

     Each U.S. Borrower covenants that, so long as any of the Obligations remain
outstanding or the Working Capital Commitment is in effect, and SLQ covenants
that so long as any of the obligations under the Canadian Term Loan Repayment
Obligations remain outstanding unless the Lender shall otherwise consent in
writing:

          7.1  Taxes and Other Obligations. Such Borrower shall, and shall cause
               ---------------------------  
     each of its Subsidiaries to (a) file when due all tax returns and other
     reports which it is required to file (taking into account any allowed
     extensions), (b) pay, or provide for the payment, when due, of all taxes,
     fees, assessments and other governmental charges against it or upon its
     Property, income and franchises, make all required withholding and other
     tax deposits, and establish adequate reserves for the payment of all such
     items, and provide to the Lender, upon request, satisfactory evidence of
     its timely compliance with the foregoing and (c) pay when due all claims of
     materialmen, mechanics, carriers, warehousemen, landlords and other like
     Persons, and all other indebtedness owed by it and perform and discharge in
     a timely manner all other obligations undertaken by it; provided, however,
                                                             --------  -------
     that such Borrower and its Subsidiaries need not pay any tax, fee,
     assessment, governmental charge, or Debt, or discharge any other
     obligation, that any of them is contesting in Good Faith by appropriate
     proceedings diligently pursued, and for which adequate reserves are
     maintained, so long as no Lien, other than a Permitted Lien, results from
     such non-payment.

          7.2  Corporate Existence and Good Standing. Such Borrower shall, and
               -------------------------------------
     shall cause each of its Subsidiaries to, maintain its corporate existence
     and its qualification and good standing in all jurisdictions necessary to
     conduct its business and own its Property, and shall obtain and maintain
     all licenses, permits, franchises and governmental authorizations necessary
     to conduct its business and own its Property.

          7.3  Compliance with Law and Agreements. Such Borrower shall, and
               ----------------------------------
     shall cause each of its Subsidiaries to, comply with the terms and
     provisions of each judgment, law, statute, rule, and governmental
     regulation applicable to it and each contract, mortgage, lien, lease,
     indenture, order, instrument, agreement, or document to which it is a party
     or by which it is bound, the failure to comply with which, whether
     considered individually or when aggregated with all other failures, is
     likely to have a material adverse effect on the ability of such Borrower to
     perform its obligations under this Agreement, or on the business,
     operations, properties or condition (financial or otherwise) of such
     Borrower, taken as a whole; provided, however, that such Borrower shall
                                 --------  -------
     have the right to contest the imposition of such laws, rules, regulations,
     court orders, decrees and governmental agency orders if such contest is
     made in Good Faith and diligently pursued by proper proceedings, adequate
     reserves with respect thereto have been established in accordance with
     GAAP, and such contest could not reasonably be expected to have a material
     adverse affect on the ability of such Borrower to perform its

                                      -69-
<PAGE>
 
     obligations under this Agreement, or the business, operations, properties
     or condition (financial or otherwise) of such Borrower, taken as a whole.

          7.4  Maintenance of Property. Such Borrower shall, and shall cause
               -----------------------
     each of its Subsidiaries to, maintain all of its Property necessary and
     useful in its business in good operating condition and repair, ordinary
     wear and tear excepted.

          7.5  Insurance.
               ---------  

               (a)  Such Borrower shall maintain, and shall cause each of its
          Subsidiaries to maintain, with financially sound and reputable
          insurers, insurance against loss or damage by fire with extended
          coverage; public liability and third party property damage; and such
          other hazards or of such other types as is customary for Persons
          engaged in the same or similar business, as the Lender shall
          reasonably specify, in amounts, and under policies reasonably
          acceptable to the Lender.

               (b)  Such Borrower shall cause the Lender to be named in each
          such policy as secured party or mortgagee and lender's loss payee or
          additional insured, as appropriate, in a manner acceptable to the
          Lender. Each policy of insurance shall contain a clause or endorsement
          requiring the insurer to give not less than thirty (30) days' prior
          written notice to the Lender in the event of cancellation of the
          policy for any reason whatsoever and a clause or endorsement stating
          that the interest of the Lender shall not be impaired or invalidated
          by any act or neglect of such Borrower, any of its Subsidiaries, or
          the owner of any premises for purposes more hazardous than are
          permitted by such policy. All premiums for such insurance shall be
          paid by such Borrower or its Subsidiaries, or by others for their
          account, when due, and certificates of insurance and, if requested,
          photocopies of the policies shall be delivered to the Lender. If such
          Borrower fails to procure (or cause to be procured) such insurance or
          to pay (or cause to be paid) the premiums therefor when due, the
          Lender may (but shall not be required to) do so and such amounts shall
          be due and payable on demand.

               (c)  Such Borrower shall promptly notify the Lender of any
          material loss, damage, or destruction to the Properties of such
          Borrower or arising from its use, whether or not covered by insurance.
          In the absence of any Default or Events of Default, such Borrower
          shall have the right to determine, whether and to what extent such
          proceeds shall be used for repair or replacement. If, however, any
          Default or Event of Default shall be continuing, the Lender may
          determine, in its sole discretion, whether the proceeds shall be used
          for repair or replacement. If neither an Event of Default nor a
          Default exists, such Borrower or its Subsidiary, as the case may be,
          may negotiate a settlement regarding such proceeds with the applicable
          insurance company and the Lender shall forward such proceeds to the
          applicable Borrower. If, however, an Event of Default or a Default
          exists, the Lender shall collect the insurance proceeds directly and 

                                      -70-
<PAGE>
 
          neither such Borrower nor its Subsidiary, as the case may be, shall
          enter into any settlement agreement with the applicable insurance
          company without the prior written consent of Lender, which consent
          shall not be unreasonably withheld. Any insurance proceeds paid to any
          Borrower not used to replace the property which suffered the casualty
          giving rise to the payment of such insurance proceeds within 180 days
          of receipt of such proceeds by such Borrower, shall be required to be
          paid to the Lender as a Mandatory Prepayment in accordance with
          Section 2.6(b).
          -------------

               (d)  If an Event of Default shall exist, Lender may, and if a
          decision to not rebuild or replace is made, the Lender shall, apply
          the proceeds of insurance to the payment of the Obligations of which
          such Borrower is liable as set forth in Section 2.10(e).
                                                  --------------

          7.6  Condemnation. Such Borrower shall, immediately upon learning of
               ------------
     the institution of any proceeding for the condemnation or other taking of
     any of its Property or the Property of any of its Subsidiaries, which has a
     material and adverse effect on the operations of such Borrower, notify the

                  money aggregating in excess of $100,000 shall be rendered
                  against any Borrower which is not discharged in full or stayed
                  within thirty (30) days from the date of entry thereof unless
                  such judgments are (i) covered by such Borrower's liability
                  insurance as confirmed in writing by the insurance company
                  carrying such insurance, or (ii) the subject of an obligation
                  of any Person (other than a Borrower or any Affiliate of any
                  Borrower) to indemnify such Borrower against whom such
                  judgment is rendered provided the terms of such
                                       --------
                  indemnification and the creditworthiness of the indemnitor are
                  satisfactory to the Lender in its sole discretion;

                         (m)  any event occurs which materially and adversely
                  affects the operations and financial condition of the U.S.
                  Borrowers, taken as a whole, or SLQ; or

                         (n)  any Environmental Lien shall attach to any
                  Property of any Borrower or any Borrower or any Subsidiary
                  becomes subject to any liabilities, costs, expenses, damages,
                  fines or penalties, which is likely to have a material adverse
                  effect on the financial condition of the U.S. Borrowers, taken
                  as a whole, or SLQ arising out of or relating to (i) the
                  release at any location of any Contaminant into the
                  environment, or the incurrence of remediation costs in
                  response thereto, or (ii) any violation of any Environmental
                  Laws.

                  9.2    Remedies.
                         -------- 

                         (a)  If an Event of Default exists, the Lender may
                  without notice to or demand on any Borrower, do one or more of
                  the following at any time or times and in any order: (i)
                  reduce the amount of the Working Capital Commitment, and (ii)
                  restrict the amount of or refuse to make Working Capital
                  Loans. If an Event of Default exists, the Lender may, without
                  notice to or demand on any Borrower, do one or more of the
                  following, in addition to the actions described in the
                  preceding sentence, at any time or times and in any order: (i)
                  terminate the Working Capital Commitment and (ii) declare any
                  or all Obligations to be immediately due and payable
                  (provided, however that upon the occurrence of any
                   --------  -------

                                      -82-
<PAGE>
 
                  Event of Default described in Sections 9.1(f), 9.1(g), 9.1(h),
                                                ---------------  ------  ------
                  or 9.1(i), all Obligations shall automatically become
                     ------
                  immediately due and payable without notice or demand of any
                  kind); and (iii) pursue its other rights and remedies under
                  the Loan Documents and applicable law.

                         (b)  If an Event of Default exists: (i) the Lender
                  shall have, in addition to all other rights, the rights and
                  remedies of a secured party under the UCC and under all other
                  applicable laws of the Province of Quebec, Canada; (ii) the
                  Lender may, at any time, take possession of the Properties of
                  such Borrower and keep such Properties on the premises of each
                  Borrower, at no cost to the Lender, or remove any part of it
                  to such other place or places as the Lender may desire, or
                  each Borrower shall, upon the Lender's demand, at such
                  Borrower's cost, assemble the Properties of such Borrower
                  owned by it and make it available to the Lender at a place
                  reasonably convenient to the Lender; and (iii) the Lender may
                  sell and deliver any Properties of each Borrower at public or
                  private sales, for cash, upon credit or otherwise, at such
                  prices and upon such terms as the Lender deems advisable, in
                  its sole discretion, and may, if the Lender deems it
                  reasonable, postpone or adjourn any sale of the Properties of
                  any Borrower by an announcement at the time and place of sale
                  or of such postponed or adjourned sale without giving a new
                  notice of sale. Without in any way requiring notice to be
                  given in the following manner, each Borrower agrees that any
                  notice by the Lender of sale, disposition or other intended
                  action hereunder or in connection herewith, whether required
                  by the UCC or otherwise, shall constitute reasonable notice to
                  such Borrower if such notice is mailed by registered or
                  certified mail, return receipt requested, postage prepaid, or
                  is delivered personally against receipt, at least five (5)
                  days prior to such action to such Borrower's address specified
                  in or pursuant to Section 12.8. If any Properties of any of
                                    ------------
                  the Borrowers are sold on terms other than payment in full at
                  the time of sale, no credit shall be given against the
                  Obligations until the Lender receives payment, and if the
                  buyer defaults in payment, the Lender may resell the
                  Properties of such Borrower without further notice to any
                  Borrower. In the event the Lender seeks to take possession of
                  all or any portion of the Properties of such Borrower by
                  judicial process, each Borrower irrevocably waives: (i) the
                  posting of any bond, surety or security with respect thereto
                  which might otherwise be required; (ii) any demand for
                  possession prior to the commencement of any suit or action to
                  recover the Properties of such Borrower; and (iii) any
                  requirement that the Lender retain possession and not dispose
                  of any such Properties until after trial or final judgment.
                  Each Borrower agrees that the Lender has no obligation to
                  preserve rights to the Properties of such Borrower or marshall
                  any such Properties for the benefit of any Person. The Lender
                  is hereby granted a license or other right to use, without
                  charge, each Borrower's labels, patents, copyrights, name,
                  trade secrets, trade names, trademarks, and advertising
                  matter, or any similar property, in completing production of,
                  advertising or selling any of the Properties of such Borrower,
                  and each Borrower's rights under all licenses and all
                  franchise agreements shall inure to the Lender's benefit. The
                  proceeds of sale

                  of Collateral owned by the U.S. Borrowers shall be applied by
                  Lender against the principal and/or interest of any Loans
                  and/or any other Obligations for which the U.S. Borrowers are
                  liable and the proceeds of sale of Property owned by SLQ shall
                  be applied by Lender only against the Canadian Term Loan
                  Repayment Obligations, whether or not then due, in such order
                  of application as the Lender may determine. The Lender will
                  return any excess to the Borrowers or such other Person as
                  shall be legally entitled thereto and the Borrowers shall
                  remain liable for any deficiency.

                         (c)  After the occurrence and during the continuance of
                  an Event of Default, each of the Borrowers hereby waives all
                  rights to notice and hearing prior to the exercise by the
                  Lender of the Lender's rights to repossess the Properties of
                  such Borrower without judicial process or to replevy, attach
                  or levy upon such Properties without notice or hearing.

         Borrower therefrom, shall in any event be effective without the written
         concurrence of the Lender, which the Lender shall have the right to
         grant or withhold at its sole discretion. Any waiver or consent shall
         be effective only in the specific instance and for the specific purpose
         for which it was given. No notice to or demand on any Borrower in any
         case shall entitle such Borrower to any other or further notice or
         demand in similar or other circumstances.

                  The Lender may also grant participations in all or any part of

                  qualify the Loans under the blue sky law of any state; and
                  (ii) Lender shall make and receive all payments for the

                  make such arrangements with its participants as may be
                  necessary to accomplish the foregoing. No holder of a

         Borrower. The enumeration herein of the Lender's rights and remedies is

         not intended to be exclusive, and such rights and remedies are in
         addition to and not by way of limitation of any other rights or
         remedies that the Lender may have under the UCC or other applicable
         law. The Lender shall have the right, in its sole discretion, to
         determine which rights and remedies are to be exercised and in which
         order. The exercise of one right or remedy shall not preclude the
         exercise of any others, all of which shall be cumulative. The Lender
         may, without limitation, proceed directly against any Borrower to
         collect the Obligations without any prior recourse to the Properties of

         shall operate as a waiver of any other provision, breach, default,
         right or remedy or of the same provisions, breach, default, right or
         remedy on a future occasion. No waiver by the Lender shall affect its
         rights to require strict performance of this Agreement.

                         ------------
         be prohibited or invalid, under applicable law, it shall be ineffective
         only to such extent, without invalidating the remainder of this

                                                             -----------
         harmless from and against any and all liabilities, obligations, losses,
         damages, penalties, actions, judgments, suits, costs, expenses or
         disbursements of any kind or nature whatsoever incurred by the
         Indemnitees, whether direct, indirect or consequential, as a result of

         threatened or initiated, asserting any claim for legal or equitable
         remedy against any Person under any statute or regulation (including,
         without limitation, any federal or state securities or commercial laws
         or under any common law or equitable cause or otherwise, including any

         predecessors in interest, or the past, present or future environmental
         condition of the U.S. Borrowers, or, as the case may be, SLQ's
         Property, the presence of asbestos-containing materials at or on such
         Property, or the release or threatened release of any contaminant into
         the environment from such Property), in any way arising from or in
         connection with the negotiation, preparation, execution, delivery,
         enforcement, performance and administration of this Agreement or any

         Borrowers shall have no obligation hereunder with respect to
         indemnified liabilities arising from the gross negligence or willful
         misconduct of any Indemnitee seeking such indemnification. To the
         extent that the indemnity set forth in this Section 12.9 may be

         Borrower shall pay the maximum portion of any indemnity of which it is
         liable which it is permitted to pay under applicable law. Any
         Indemnitee will promptly notify the Borrowers of the commencement of
         any legal proceeding which may give rise to any indemnified liability

         participate in the defense of such Indemnitee in any such proceeding.
         The foregoing indemnity shall survive the payment of the Obligations
         and the termination of this Agreement. All of the foregoing fees, costs
         and expenses shall be part of the Obligations, payable upon demand, and
         secured by the Properties of such Borrower.

               12.10  Waiver of Notices.  Unless otherwise expressly provided
                      -----------------
         herein, each Borrower waives presentment, protest and notice of demand
         or dishonor and protest as to any instrument, as well as any and all
         other notices to which it might otherwise be entitled. No notice to or
         demand on any Borrower which the Lender may elect to give shall entitle
         such Borrower to any or further notice or demand in the same, similar
         or other circumstances.

               12.11  Counterparts.  This Agreement may be executed in any
                      ------------
         number of counterparts, and by the Lender and each of the Borrowers in
         separate counterparts, each of which shall be an original, but all of
         which shall together constitute one and the same agreement.

               12.12  Captions.  The captions contained in this Agreement are
                      --------

         construed to modify, enlarge, or restrict any provision.

               12.13  Contribution.  To the extent that any of the U.S.
                      ------------
         Borrowers shall, under the terms of this Agreement or any Note or any
         other Loan Document, make a payment of a portion of the Obligations
         which, taking into account all other concurrent payments of the
         Obligations by the U.S. Borrowers collectively, shall exceed the amount
         which such U.S. Borrower has actually received under the Credit
         Facilities or would have otherwise paid if each U.S. Borrower had paid
         the aggregate Obligations satisfied by such payments in the same
         proportion as such U.S. Borrower's Net Worth immediately prior to such
         payments bore to the aggregate amount of all the U.S. Borrowers' Net
         Worth immediately prior to such payment; then such U.S. Borrower shall
         be entitled to contribution from, and be reimbursed by, the other U.S.
         Borrowers for the amount of such excess, pro rata based on their
         respective Net Worth immediately prior to such payment. This agreement
         regarding contribution is intended to define the relative rights of the
         U.S. Borrowers, and nothing set forth in this Section 12.13 is intended
                                                       -------------
         to or shall impair the obligations of the U.S. Borrowers, jointly and
         severally, to pay the Obligations as and when the same shall become due
         and payable in accordance with this Agreement and the Notes.

               12.14  Joint and Several Liability.  The obligations of the U.S.
                      ---------------------------
         Borrowers to repay the Working Capital Loans, the A Term Loan and the B
         Term Loan (the "U.S. Loan Repayment Obligations") and all other amounts
         due under and in connection with such Loans shall be joint and several
         obligations of the U.S. Borrowers and not SLQ. Each U.S. Borrower shall
         be liable for the full amount of the U.S. Loan Repayment Obligations
         with the rights of contribution and reimbursement against the other
         U.S.

         to time supplied to it by any Borrower under this Agreement unless such

         bank examiners and auditors; and (iii) any transferee or prospective
         transferee of any Note; or (c) any other Person in connection with any
         litigation to which the Lender is a party; provided, further, that the
                                                    --------  -------
         Lender hereby agrees that it will notify the Borrowers in writing of
         any request for information under clauses (a) and (c) above or with
         respect to any other request for information not enumerated in this
         Section 12.15 at least five (5) Business Days before complying with any
         -------------
         such request, unless such notice is specifically prohibited by
         applicable law, court order or governmental authority. If the terms of
         any request for information subject to the last proviso of the
         preceding sentence do not provide a reasonably sufficient time to give
         the Borrowers five (5) Business Days' notice, the Lender will use its
         best efforts to seek additional time for compliance in order to permit
         such notice and in any event will notify the Borrowers of such request
         as soon as practicable.

               12.16  Absence of Financial Assistance by SLQ.  For greater
                      --------------------------------------
         certainty, the parties hereto acknowledge and agree that
         notwithstanding anything to the contrary in this Agreement or any other
         Loan Documents (i) the Obligations of the U.S. Borrowers under this
         Agreement and any other Loan Documents are solely those of the U.S.
         Borrowers and not SLQ (which shall have no liability therefor), (ii)
         none of the provisions of this Agreement or any other Loan Documents
         are intended to result in SLQ furnishing any form of "financial
         assistance" (including, without limitation, by giving security) within
         the meaning of Section 123.66 of the Companies Act (Quebec) to or for
         the benefit of the U.S. Borrowers, (iii) any indemnities or other
         amounts owing under Section 12.7 or 12.9 hereof for which the U.S.
         Borrowers and SLQ may be deemed to be jointly and severally liable
         shall instead constitute the several obligations of the U.S. Borrowers
         and shall not be obligations of SLQ and (iv) under no circumstances
         shall SLQ be required by the terms of this Agreement or any other Loan
         Documents to provide "financial assistance" to any of the U.S.
         Borrowers (as such term may be interpreted by a court of competent
         jurisdiction in Quebec in considering the application of Section 123.66
         of the Companies Act (Quebec)).

               12.17  Judgment Currency.  (a) If for the purposes of obtaining
                      -----------------
         judgment in any court it is necessary to convert all or any part of the
         Obligations or any other amount due to the Lender hereunder or under
         any security in respect of the obligations of any of the Borrowers
         hereunder in any currency (the "Original Currency") into another
         currency (the "Other Currency") such Borrower, to the fullest extent
         that it may effectively do so, agrees that the rate of exchange used
         shall be that at which, in accordance with normal banking procedures,
         the Lender could purchase the Original Currency with the Other Currency
         at its principal offices in Chicago on a Business Day on which the
         Lender is open for the transaction of its banking business at such
         offices immediately preceding the day on which any such judgment, or
         any relevant part thereof, is paid or otherwise satisfied.

                      (b)  The obligations of any of the Borrowers in respect of
         any sum due in the Original Currency from such Borrower to the Lender
         hereunder or under any security in respect of such Borrower's
         obligations hereunder shall, notwithstanding any judgment in any Other
         Currency, be discharged only to the extent that on the Business Day
         following receipt by the Lender of any sum adjudged to be so due in
         such Other Currency or of any other sum in any Other Currency the
         Lender may, in accordance with its normal banking procedures, purchase
         the Original Currency with such Other Currency. If the amount of the
         Original Currency so purchased is less than the sum originally due to
         the Lender in the Original Currency, such Borrower shall, as a separate
         obligation and notwithstanding any such judgment, indemnify the Lender
         against such loss, and if the amount of the Original Currency so
         purchased exceeds the sum originally due to the Lender, the Lender
         shall remit such excess to the such Borrower.

                       EMONS TRANSPORTATION GROUP, INC.
                      COMPLETES PURCHASE OF RAIL LINE IN
                     QUEBEC, CANADA FROM CANADIAN NATIONAL

York, Pennsylvania; December 23, 1998... Emons Transportation Group, Inc.,
(Nasdaq/SmallCap: EMON) today announced that, subject to making certain filings
relating to its financing, it has completed the acquisition of a 94-mile rail
line in Quebec, Canada, through a newly formed subsidiary, the St. Lawrence &
Atlantic Railroad (Quebec) Inc. ("SLQ") for Can$7,000,000. On July 23, 1998,
Emons announced an Agreement In Principle to acquire this rail line, designated
as the "Sherbrooke Line", from Canadian National ("CN").

     The Sherbrooke Line connects with CN's Halifax-to-Montreal main line at
Ste. Rosalie, Quebec, and Emons' New England operations, the St. Lawrence &
Atlantic Railroad Company ("SLR"), at the Quebec/Vermont international border.
Based on current levels of business, SLQ will handle about 23,000 carloads of
freight in the first 12 months of operations, as well as 10,000 to 12,000
intermodal trailers and containers traveling between SLR and CN. On an
annualized basis, it is expected that this new rail operation will increase
Emons' revenues by 20% to 25%. Emons has purchased ten 2,000 horsepower
locomotives in connection with this transaction, as well as certain other
equipment and materials. As a result of this transaction closing later than
anticipated, SLQ began operating the line on December 1, 1998, under an interim
agreement with CN.

     Emons further announced that this acquisition was financed by LaSalle
National Bank of Chicago. The Company's existing loan agreement with LaSalle was
amended to include funding for this transaction, which includes a Can$6.6
million seven-year term loan, and a U.S. $2 million three-year term loan.
Borrowing under this facility will bear interest at variable rates based, at the
Company's option, on either LaSalle's prime rate or the EURODOLLAR rate with
respect to U.S. borrowings and CDOR rate with respect to Canadian borrowings.

     Robert Grossman, Chairman and Chief Executive Officer, commented, "It is
particularly gratifying to have completed this acquisition, since it is in line
with our goal of making contiguous or nearby rail acquisitions to strengthen our
existing rail franchises in the New England and Mid-Atlantic regions. Our New
England/Quebec rail franchise will be expanded to 260 contiguous main line miles
by the acquisition of this rail line. We believe there will be many synergies
between SLQ and SLR from both a cost and business development viewpoint. We are
very hopeful that we will be able to grow SLQ's business and continue to grow
SLR's business as a result of this transaction."

     Mr. Grossman concluded, "We expect to continue our two-tier strategy of
internal growth and selective acquisitions. This is the fourth, but most
significant in terms of size, acquisition that Emons has completed in the past
year."

     Emons Transportation Group, Inc., is a freight transportation and
distribution services Company serving the Mid-Atlantic and Northeast regions
through its Pennsylvania and New England/Quebec operations. Emons currently owns
five short line railroads, operates rail/truck transfer facilities and a rail
intermodal terminal, and provides its customers with warehousing and logistics
services for the movement and storage of their freight.
