Required Payment to the Agent within three Business Days of the Advance Date,
then, retroactively to the Advance Date, the Payor and the recipient(s) shall
each be obligated to pay interest on the Required Payment as follows:

            (i) if the Required Payment shall represent a payment to be made by
      the Company to the Lenders, the recipient(s) shall be obligated
      retroactively to the Advance Date to pay interest in respect of the
      Required Payment at the Post-Default Rate (and, in case the recipient(s)
      shall return the Required Payment to the Agent, without limiting the
      obligation of the Company under Section 3.02 hereof to pay interest to
      such recipient(s) at the Post-Default Rate in respect of the Required
      Payment) and

            (ii) if the Required Payment shall represent proceeds of a Loan to
      be made by the Lender to the Company, the Payor and the Company shall each
      be obligated retroactively to the Advance Date to pay interest in respect
      of the Required Payment at the rate of interest provided for such Required
      Payment pursuant to Section 3.02 hereof (and, in case the Company shall
      return the Required Payment to the Agent, without limiting any claim the
      Company may have against the Payor in respect of the Required Payment).

      4.07  Sharing of Payments, Etc.

      (a) The Company agrees that, in addition to (and without limitation of)
any right of set-off, banker's lien or counterclaim a Lender may otherwise have,
each Lender shall be entitled, at its option, to offset balances held by it for
account of the Company at any of its offices, in Dollars or in any other
currency, against any principal of or interest on any of such Lender's Loans or
any other amount payable to such Lender hereunder, that is not paid when due
(regardless of whether such balances are then due to the Company), in which case
it shall promptly notify the Company and the Agent



                                      -33-
<PAGE>   34
thereof, provided that such Lender's failure to give such notice shall not
affect the validity thereof.

      (b) If any Lender shall obtain from any Obligor payment of any principal
of or interest on any Loan owing to it or payment of any other amount under this
Agreement or any other Basic Document through the exercise of any right of
set-off, banker's lien or counterclaim or similar right or otherwise (other than
from the Agent as provided herein), and, as a result of such payment, such
Lender shall have received a greater percentage of the principal of or interest
on the Loans or such other amounts then due hereunder or thereunder by such
Obligor to such Lender than the percentage received by any other Lender, it
shall promptly purchase from such other Lenders participations in (or, if and to
the extent specified by such Lender, direct interests in) the Loans or such
other amounts, respectively, owing to such other Lenders (or in interest due
thereon, as the case may be) in such amounts, and make such other adjustments
from time to time as shall be equitable, to the end that all the Lenders shall
share the benefit of such excess payment (net of any expenses that may be
incurred by such Lender in obtaining or preserving such excess payment) pro rata
in accordance with the unpaid principal of and/or interest on the Loans or such
other amounts, respectively, owing to each of the Lenders. To such end all the
Lenders shall make appropriate adjustments among themselves (by the resale of
participations sold or otherwise) if such payment is rescinded or must otherwise
be restored.

      (c) The Company agrees that any Lender so purchasing such a participation
(or direct interest) may exercise all rights of set-off, banker's lien,
counterclaim or similar rights with respect to such participation as fully as if
such Lender were a direct holder of Loans or other amounts (as the case may be)
owing to such Lender in the amount of such participation.

      (d) Nothing contained herein shall require any Lender to exercise any such
right or shall affect the right of any Lender to exercise, and retain the
benefits of exercising, any such right with respect to any other indebtedness or
obligation of any Obligor. If, under any applicable bankruptcy, insolvency or
other similar law, any Lender receives a secured claim in lieu of a set-off to
which this Section 4.07 applies, such Lender shall, to the extent practicable,
exercise its rights in respect of such secured claim in a manner consistent with
the rights of the Lender entitled under this Section 4.07 to share in the
benefits of any recovery on such secured claim.

      Section 5.  Yield Protection, Etc.

      5.01  Additional Costs.

      (a) The Company shall pay directly to the Agent on behalf of any Lender
from time to time such amounts as any Lender may determine to be necessary to



                                      -34-
<PAGE>   35
compensate such Lender for any costs that such Lender determines are
attributable to its making or maintaining of any Loans or its obligation to make
any Loans hereunder, or any reduction in any amount receivable by such Lender
hereunder in respect of any Loans or such obligation (such increases in costs
and reductions in amounts receivable being herein called "Additional Costs"),
resulting from any Regulatory Change that:

            (i) shall subject any Lender (or its Lending Office) to any tax,
      duty or other charge in respect of such Loans or its Notes or changes the
      basis of taxation of any amounts payable to such Lender under this
      Agreement or its Notes in respect of Loans (excluding changes in the rate
      of tax on the overall net income of such Lender or of such Lending Office
      by the jurisdiction in which such Lender has its principal office or such
      Lending Office); or

            (ii) imposes or modifies any reserve, special deposit or similar
      requirements relating to any extensions of credit or other assets of, or
      any deposits with or other liabilities of, such Lender (including, without
      limitation, any of such Loans or any deposits referred to in the
      definition of "Eurodollar Rate" in Section 1.01 hereof), or any commitment
      of such Lender (including, without limitation, the Commitment of such
      Lender hereunder); or

            (iii) imposes any other condition affecting this Agreement or its
      Notes (or any of such extensions of credit or liabilities) or its
      Commitment.

      (b) Without limiting the effect of the foregoing provisions of this
Section 5.01 (but without duplication), the Company shall pay to the Agent on
behalf of any Lender from time to time on request such amounts as such Lender
may determine to be necessary to compensate such Lender (or, without
duplication, the bank holding company of which such Lender is a subsidiary) for
any costs that it determines are attributable to the maintenance by such Lender
(or any Lending Office or such bank holding company), pursuant to any law or
regulation or any interpretation, directive or request (having the force of law
and where the failure to comply therewith would be unlawful) of any court or
governmental or monetary authority (i) following any Regulatory Change or (ii)
implementing any risk-based capital guideline or other requirement (having the
force of law and where the failure to comply therewith would be unlawful)
heretofore or hereafter issued by any government or governmental or supervisory
authority implementing at the national level the Basle Accord, of capital in
respect of its Commitments or Loans (such compensation to include, without
limitation, an amount equal to any reduction of the rate of return on assets or
equity of such Lender (or any Lending Office or such bank holding company) to a
level below that which such Lender (or any Lending Office or such bank holding
company) could have achieved but for such law, regulation, interpretation,
directive or request). For purposes of this Section 5.01(b), "Basle Accord"
shall mean the proposals for risk-based capital framework described by the Basle
Committee on Banking Regulations and Supervisory Practices in its paper entitled
"International Convergence of Capital Measurement and Capital Standards" dated
July 1988, as amended, modified and supplemented and in effect



                                      -35-
<PAGE>   36
from time to time or any replacement thereof.

      (c) Each Lender shall notify the Agent (who shall in turn notify the
Company) of any event occurring after the date of this Agreement entitling such
Lender to compensation under paragraph (a) or (b) of this Section 5.01 as
promptly as practicable, but in any event within 45 days, after such Lender
obtains actual knowledge thereof; provided that (i) if any Lender fails to give
such notice within 45 days after it obtains actual knowledge of such an event,
such Lender shall, with respect to compensation payable pursuant to this Section
5.01 in respect of any costs resulting from such event, only be entitled to
payment under this Section 5.01 for costs incurred from and after the date 45
days prior to the date that such Lender does give such notice and (ii) each
Lender will designate a different Lending Office for the Loans of such Lender if
such designation will avoid the need for, or reduce the amount of, such
compensation and will not, in the sole opinion of such Lender, be
disadvantageous to such Lender, except that such Lender shall have no obligation
to designate a Lending Office located in the United States of America. Each
Lender will furnish to the Company a certificate setting forth the basis and
amount of each request by such Lender for compensation under paragraph (a) or
(b) of this Section 5.01. Determinations and allocations by any Lender for
purposes of this Section 5.01 of the effect of any Regulatory Change pursuant to
paragraph (a) or (b) of this Section 5.01, or of the effect of capital
maintained pursuant to paragraph (b) of this Section 5.01, on its costs or rate
of return of maintaining Loans or its obligation to make Loans, or on amounts
receivable by it in respect of Loans, and of the amounts required to compensate
such Lender under this Section 5.01, shall be conclusive, provided that such
determinations and allocations are made on a reasonable basis.

      5.02 Illegality. Notwithstanding any other provision of this Agreement, in
the event that it becomes unlawful for any Lender or its Lending Office to honor
its obligation to make or maintain any of its Loans hereunder (and, in the
reasonable opinion of such Lender, the designation of a different Lending Office
would either not avoid such unlawfulness or would be disadvantageous to the
Lender), then such Lender shall immediately notify the Agent, and such Lender's
obligation to maintain or continue Loans bearing interest at the Eurodollar Rate
shall be suspended (until such Lender shall notify the Agent that the
circumstances causing such unlawfulness no longer exist), whereupon such
Lender's Loans shall automatically convert into Loans bearing interest at the
Base Rate and such Lender shall not be entitled to compensation from the Company
of the type set forth in Section 5.04 hereof resulting therefrom.

      5.03  Taxes.

      (a) All payments on account of the principal of and interest on the Loans,
fees and all other amounts payable hereunder by the Company to or for the
account of the Agent or any Lender, including, without limitation, amounts
payable under clause (b) of



                                      -36-
<PAGE>   37
this Section 5.03, shall be made free and clear of and without reduction or
liability for Mexican Taxes. The Company will pay all Mexican Taxes for its
account, prior to the date on which penalties attach thereto, except for any
Mexican Taxes (other than Mexican Taxes imposed on or in respect of any amount
payable hereunder, under the Notes or under any other Basic Document) the
payment of which is being contested in good faith and by proper proceedings and
against which adequate reserves are being maintained, so long as no claim for
such Mexican Taxes is made on the Agent or any Lender. If, as a result of the
making of any deduction or withholding of Mexican Taxes under this Section 5.03,
and the Agent or a Lender obtains the benefit of a credit or relief against or
repayment of any tax through an actual reduction in taxes paid or receipt of a
refund (a "Tax Credit"), the Agent or Lender, as the case may be, shall
reimburse to the Company an amount equal to the proportion of the Tax Credit as
will leave the Agent or Lender after such reimbursement in no better or worse
position (on an after tax basis) than it would have been in if such deduction or
withholding had been made and such increased payment had not been required.
Nothing in this clause shall obligate the Agent or Lender to utilize such Tax
Credit in priority to any other credit or relief available to it for tax
purposes, but the Agent or Lender shall otherwise take reasonable steps to
obtain the benefit of such Tax Credit. If the benefit obtained by the Agent or
Lender through use of the Tax Credit is reduced or eliminated after payment has
been made to Company under this Section 5.03 (through adjustment to the Agent's
or Lender's tax return or otherwise), the Company shall be obligated to repay to
such Agent or Lender the amount by which the tax benefit to the Agent or Lender
is reduced. Nothing in this clause shall obligate the Agent or Lender to
disclose any information regarding its tax affairs or computations to the
Company.

      (b) The Company shall indemnify the Agent and each Lender against, and
reimburse the Agent and each Lender on demand for, any Mexican Taxes and any
loss, liability, claim or expense, including interest, penalties and legal fees,
which the Agent or such Lender (as the case may be) may incur at any time
arising out of or in connection with any failure of the Company to make any
payment of Mexican Taxes when due.

      (c) In the event that the Company is required by applicable law, decree or
regulation to deduct or withhold Mexican Taxes from any amounts payable on,
under or in respect of this Agreement or the Loans (including, without
limitation, the Mexican income taxes referred to in clause (f) of this Section
5.03), the Company shall promptly pay the Person entitled to such amount such
additional amounts as may be required, after the deduction or withholding of
Mexican Taxes to enable such Person to receive from the Company, on the due date
thereof, an amount equal to the full amount stated to be payable to such Person
under this Agreement.

      (d) The Company shall not be obligated to pay the Agent or any Lender any
additional amounts described in Section 5.03(c) in respect of Mexican Taxes to
the extent that such Mexican Taxes or any portion thereof have been imposed as a
result of: (A) the failure of any Lender (i) to provide to the Company, upon the
written request




                                      -37-
<PAGE>   38
of the Company and if and when required under applicable law, a letter
specifying that such Lender is the effective beneficiary of interest hereunder
and under the Note held by such Lender, as set forth in the Resolucion
Miscelanea Fiscal para 1997 or any equivalent administrative regulations in
effect thereafter while this Agreement shall remain in full force and effect,
(ii) following a reasonable written request of the Company, to complete and to
file with the appropriate governmental authority (at the Company's expense), or
to provide to the Company, such forms, certificates, documents, information,
applications, declarations or returns prescribed by any law, rule or regulation
enacted or issued by Mexico or any political subdivision thereof or authority
therein, or a double taxation treaty to which Mexico is a party and which is in
effect, that are necessary to avoid or reduce such Mexican Taxes pursuant to
provisions of any law, rule or regulation enacted or issued by Mexico or any
political subdivision thereof or authority therein, or a double taxation treaty
to which Mexico is a party and which in effect (provided that such Lender shall
be under no obligation to provide to the Company or to file with any
governmental authority any such forms, certificates, documents, information,
applications, declarations or returns which contain any information that such
Lender reasonably deems to be confidential or proprietary, and the provision or
the filing of which would, in the reasonable judgment of such Lender, be
materially adverse to such Lender, or (iii) to maintain its registration with
the Ministry of Finance and Public Credits as a foreign financial institution
for purposes of the Mexican Income Tax Law, the rules thereunder (or any
successor statute or rules) and any administrative regulations (resoluciones
miscelaneas) thereunder so long as such requirement remains applicable and such
Lender remains legally entitled to maintain such registration or (B) the
redesignation of the Lender's Lending Office to another jurisdiction (except if
such redesignation results from an event of illegality described in 5.03
hereof).

      (e) Each Lender that is not organized under the laws of Mexico and that is
a signatory hereto represents and warrants that, as of the date hereof, such
Lender is (i) registered with the Ministry of Finance and Public Credit as a
foreign financial institution for purposes of the Mexican Income Tax Law, the
rules thereunder and any administrative regulations (resoluciones miscelaneas)
thereunder and (ii) a resident for tax purposes of a jurisdiction with which
Mexico has in effect a treaty for the avoidance of double taxation.

      (f) The Company represents and warrants to the Lenders and the Agent that,
on and as of the date of this Agreement and assuming the accuracy of the
representations made by each Lender in Section 5.03(e), none of this Agreement,
any other Basic Document, or the execution or delivery by the Company of this
Agreement or any other Basic Document, is subject to any Mexican Taxes, and no
payment to be made by the Company under this Agreement is subject to any Mexican
Taxes, except for Mexican income taxes at the rate of 4.9% on amounts payable by
the Company hereunder (other than principal of the Loans) required to be
withheld and paid by the Company.

      (g) The Company shall furnish to the Agent, upon the request of any Lender




                                      -38-
<PAGE>   39
(through the Agent), original official tax receipts, or certified copies
thereof, in respect of each payment of Mexican Taxes required under this Section
5.03, when it delivers the compliance certificate required to be delivered
pursuant to Section 9.01 hereof, and the Company shall promptly furnish to the
Agent at its request or at the request of any Lender (through the Agent) any
other information, documents and receipts that the Agent or such Lender may
reasonably require to establish to its satisfaction that full and timely payment
has been made of all Mexican Taxes required to be paid under this Section 5.03.

      (h) If any Obligor is required to pay additional amounts to or for the
account of any Lender pursuant to this Section 5.03 in excess of any additional
amounts that may be payable on the Closing Date (and, in the case of a Lender
that becomes a Lender hereunder after the Closing Date, in excess of any
additional amounts that would have been payable had such Lender been a Lender on
the Closing Date), then such Lender will designate a different Lending Office
for the Loans of such Lender if such designation would eliminate or reduce any
such excess additional amounts and would not, in the reasonable opinion of such
Lender, be disadvantageous to such Lender.

      5.04 Compensation. The Company shall pay to the Agent for account of each
Lender, upon the request of such Lender through the Agent, such amount or
amounts as shall be sufficient (in the reasonable opinion of such Lender) to
compensate it for any loss, cost or expense that such Lender determines is
attributable to:

            (a) any payment or mandatory or optional prepayment of a Loan made
      by such Lender for any reason (including, without limitation, the
      acceleration of the Loans pursuant to Section 10 hereof) on a date other
      than the last day of an Interest Period for such Loan; or

            (b) any failure by the Company for any reason (including, without
      limitation, the failure of any of the conditions precedent specified in
      Section 7 hereof to be satisfied) to borrow a Loan from such Lender on the
      date for such borrowing specified in the relevant notice of borrowing
      given pursuant to Section 2.02 hereof.

Without limiting the effect of the preceding sentence, such compensation shall
include an amount equal to the excess, if any, of (i) the amount of interest
that otherwise would have accrued on the principal amount so paid, prepaid, or
not borrowed for the period from the date of such payment, prepayment, or
failure to borrow to the last day of the then current Interest Period for such
Loan (or, in the case of a failure to borrow, the Interest Period for such Loan
that would have commenced on the date specified for such borrowing) at the
applicable rate of interest for such Loan provided for herein over (ii) the
amount of interest that otherwise would have accrued on such principal amount at
a rate per annum equal to the interest component of the amount such Lender would
have bid in the London interbank market for Dollar deposits of leading banks in
amounts comparable to such principal amount and with maturities comparable to
such


                                      -39-
<PAGE>   40
 period (as reasonably determined by such Lender).

      5.05 Replacement of Lenders. Each Lender agrees that if it makes any
demand for payment under Sections 5.02 or 5.03 hereof, and such demand is made
as a result of the failure by such Lender to maintain its registration with the
Ministry of Finance and Public Credits as a foreign financial institution for
purposes of the Mexican Income Tax Law and the rules thereunder (where such
Lender remains legally entitled to maintain such registration), so long as no
Event of Default has occurred and is continuing, at the request of the Company,
such Lender shall assign its Loans (i) to one or more assignees agreeing to
purchase such Loans and identified either by the Company or the Agent (who
shall, upon request by the Company, use its reasonable efforts to identify an
assignee) by written notice to such Lender or, which assignees (if identified by
the Company) shall be reasonably acceptable to the Agent, and shall otherwise
satisfy the requirements of Section 12.07 hereof, (ii) in an amount on the date
of such assignment equal to the amount that would be payable to such Lender if
such assignment were a prepayment in full of such Lender's Loans and (iii)
pursuant to documentation reasonably satisfactory to such Lender.

      Section 6.  Guarantee.

      6.01 The Guarantee. The Guarantors hereby jointly and severally guarantee
to each Lender and the Agent and their respective successors and assigns the
prompt payment in full when due (whether at stated maturity, by acceleration or
otherwise) of the principal of and interest on the Loans made by the Lenders to,
and the Notes held by each Lender of, the Company and all other amounts from
time to time owing to the Lenders or the Agent by the Company under this
Agreement and under the Notes and by the Company under any of the other Basic
Documents (including amounts payable in accordance with Sections 5 and 12.04
hereof), in each case strictly in accordance with the terms thereof (such
obligations being herein collectively called the "Guaranteed Obligations"). The
Guarantors hereby further jointly and severally agree that if the Company shall
fail to pay in full when due (whether at stated maturity, by acceleration or
otherwise) any of the Guaranteed Obligations, the Guarantors will promptly pay
the same, without any demand or notice whatsoever, and that in the case of any
extension of time of payment or renewal of any of the Guaranteed Obligations,
the same will be promptly paid in full when due (whether at extended maturity,
by acceleration or otherwise) in accordance with the terms of such extension or
renewal.

      6.02 Obligations Unconditional. The obligations of the Guarantors under
Section 6.01 hereof are absolute and unconditional, joint and several,
irrespective of the value, genuineness, validity, regularity or enforceability
of the obligations of the Company under this Agreement, the Notes or any other
agreement or instrument referred to herein or therein, or any substitution,
release or exchange of any other guarantee of or security for any of the
Guaranteed Obligations, and, to the fullest extent permitted by applicable law,
irrespective of any other circumstance whatsoever that



                                      -40-
<PAGE>   41
might otherwise constitute a legal or equitable discharge or defense of a surety
or guarantor, it being the intent of this Section 6.02 that the obligations of
the Guarantors hereunder shall be absolute and unconditional, joint and several,
under any and all circumstances. Without limiting the generality of the
foregoing, it is agreed that the occurrence of any one or more of the following
shall not alter or impair the liability of the Guarantors hereunder which shall
remain absolute and unconditional as described above:

            (i) at any time or from time to time, without notice to the
      Guarantors, the time for any performance of or compliance with any of the
      Guaranteed Obligations shall be extended, or such performance or
      compliance shall be waived;

            (ii) any of the acts mentioned in any of the provisions of this
      Agreement or the Notes or any other agreement or instrument referred to
      herein or therein shall be done or omitted;

            (iii) the maturity of any of the Guaranteed Obligations shall be
      accelerated, or any of the Guaranteed Obligations shall be modified,
      supplemented or amended in any respect, or any right under this Agreement
      or the Notes or any other agreement or instrument referred to herein or
      therein shall be waived or any other guarantee of any of the Guaranteed
      Obligations or any security therefor shall be released or exchanged in
      whole or in part or otherwise dealt with;

            (iv) insolvency, bankruptcy, reorganization, arrangement,
      adjustment, composition, assignment for the benefit of creditors,
      liquidation, winding up or dissolution of the Company or any Guarantor;

            (v) any limitation, discharge, moratorium or cessation of the
      liability of the Company or any Guarantor due to any statute, regulation,
      decree, judgment, order, stay or rule of law, or any invalidity or
      unenforceability in whole or in part of any documents evidencing the
      obligations of the Company hereunder;

            (vi) any merger, acquisition, consolidation or change in structure
      of the Company, SLT or the Trust, or any sale, lease, transfer or other
      disposition of any or all of the assets or shares or ownership interests
      of the Company, SLT or the Trust;

            (vii) any assignment or other transfer, in whole or in part, of the
      interests in and rights under this Agreement, including the right of the
      Lender to receive payment of the Guaranteed Obligations and the other
      amounts payable hereunder or any assignment or other transfer, in whole or
      in part, of the interests of the Lender in and to any collateral securing
      the Guaranteed Obligations;



                                      -41-
<PAGE>   42
            (viii) any claim, counterclaim or setoff, other than that of prior
      payment in cash in full or performance, that the Company, SLT or the Trust
      may have or assert, including any defense of incapacity or lack of
      corporate, partnership or other authority to execute any Basic Documents
      or any related documents or any collateral securing the Guaranteed
      Obligations;

            (ix) the amendment, modification, renewal, extension, cancellation
      or surrender of any agreement, document or instrument relating to any
      Basic Document or any collateral securing the Guaranteed Obligations
      (other than any cancellation or surrender reflecting prior payment in cash
      in full or performance), or the exchange, release, or waiver of any
      collateral securing the Guaranteed Obligations;

            (x) the exercise or nonexercise by the Lender of any power, right or
      remedy with respect to any of the Guaranteed Obligations or any collateral
      securing any of the Guaranteed Obligations, including the compromise,
      release, settlement or waiver by the Lender with or of the Company, the
      Trust or SLT or any other Person;

            (xi) the vote, claim, distribution, election, acceptance, action or
      inaction by the Lender in any bankruptcy case related to any of the
      Guaranteed Obligations, or any collateral securing the Guaranteed
      Obligations; or

            (xii) any impairment or invalidity of any of the collateral securing
      any of the Guaranteed Obligations or any failure to perfect (including a
      failure to perfect after the occurrence of a Default hereunder) any of the
      Liens of the Lender thereon or therein.

The Guarantors hereby expressly waive diligence, presentment, demand of payment,
protest and all notices whatsoever, and any requirement that the Agent or any
Lender exhaust any right, power or remedy or proceed against the Company under
this Agreement or the Notes or any other agreement or instrument referred to
herein or therein, or against any other Person under any other guarantee of, or
security for, any of the Guaranteed Obligations. Without notice to or further
assent from any Guarantor the Lenders may discharge or release, in whole or in
part, any Guarantor or any other Person liable for the payment and performance
of all or any part of the Guaranteed Obligations, and may permit or consent to
any such action or any result of such action, and shall not be obligated to
demand or enforce payment or performance upon any of the Guaranteed Obligations
or collateral securing any Guaranteed Obligations, nor shall the Lenders be
liable to any Guarantor or any other Person for any failure to collect or
enforce payment or performance of any of the Guaranteed Obligations or to
realize on any of the collateral securing any Guaranteed Obligation.

      6.03 Reinstatement. The obligations of the Guarantors under this Section 6



                                      -42-
<PAGE>   43
shall be automatically reinstated if and to the extent that for any reason any
payment by or on behalf of the Company in respect of the Guaranteed Obligations
is rescinded or must be otherwise restored by any holder of any of the
Guaranteed Obligations, whether as a result of any proceedings in bankruptcy or
reorganization or otherwise and the Guarantors jointly and severally agree that
they will indemnify the Agent and each Lender on demand for all reasonable costs
and expenses (including, without limitation, fees of counsel) incurred by the

of Section 6.01 hereof notwithstanding any stay, injunction or other prohibition
preventing such declaration (or such obligations from becoming automatically due
and payable) as against the Company and that, in the event of such declaration

represents and warrants to the Agent and the Lenders at all times during the
term of this Agreement that:

         8.01 Corporate Existence. Each of the Obligors (a) is a corporation,


                                      -48-
<PAGE>   49
partnership or other entity duly organized, validly existing and in good
standing under the laws of the jurisdiction of its organization; (b) has all
requisite corporate or other power, and has all material governmental licenses,
authorizations, consents and approvals necessary to own its assets and carry on
its business as now being or as proposed to be conducted; and (c) is qualified

of the business conducted by it makes such qualification necessary and where
failure so to qualify could (either individually or in the aggregate) have a
Material Adverse Effect.

         8.02 Financial Condition. The Obligors have heretofore furnished to
each of the Lenders the following:

         (i)      (a) audited and consolidated balance sheets of the Trust and
                  SLT as at December 31, 1996 and the related consolidated
                  statements of income, retained earnings and cash flow of the
                  Trust and SLT for the fiscal year ended on said date, with the
                  opinion thereon (in the case of said consolidated balance
                  sheet and statements) of a nationally recognized public
                  accounting firm,

                  (b) the unaudited consolidated balance sheets of the Trust and
                  SLT as at June 30, 1997 and the related consolidated
                  statements of income, retained earnings and cash flow of the
                  Trust and SLT for the six-month period ended on such date; and

         (ii) an opening balance sheet of each Hotel Company giving effect to

correct in all material respects and fairly present the consolidated financial
condition of the Trust and SLT, as at said dates and the consolidated results of
their operations for the fiscal year and six-month period ended on said dates
(subject, in the case of such financial statements as at June 30, 1997, to
normal year-end audit adjustments), all in accordance with generally accepted
accounting principles and practices applied on a consistent basis. None of the
Obligors has on the date hereof any material contingent liabilities, liabilities
for taxes, unusual forward or long-term commitments or unrealized or anticipated
losses from any unfavorable commitments, except as referred to or reflected or
provided for in said balance sheets as at said dates. Since December 31, 1996,

condition, operations, business or prospects taken as a whole of the Trust and
SLT from that set forth in said financial statements as at said date.

         8.03 Litigation. There are no legal or arbitral proceedings, or any
proceedings by or before any governmental or regulatory authority or agency, now

Obligors or any of their respective Subsidiaries that (x) contest the
Acquisition or (y) if adversely determined


                                      -49-
<PAGE>   50
could (in the aggregate), could reasonably be expected to have a material
adverse effect on the financial condition, operations, assets, business or
properties of the Obligors, taken as a whole. There are no legal or arbitral
proceedings, or any proceedings by or before any governmental or regulatory
authority or agency, now pending or (to the knowledge of any Obligor) threatened
against SLC Mexico or any of the Hotel Companies or any of their respective
Subsidiaries that (x) contest the Acquisition or (y) if adversely determined
could reasonably be expected to have a material adverse effect on the financial
condition, operations, assets, business or properties of the SLC Mexico and the
Hotel Companies, taken as a whole.

         8.04 No Breach. None of the execution and delivery of this Agreement
and the Notes and the other Basic Documents, the consummation of the
transactions herein and therein contemplated or compliance with the terms and
provisions hereof and thereof will conflict with or result in a breach of, or
require any consent under, the estatutos sociales, partnership agreement, or, as
the case may be, trust agreement of any Obligor, or any applicable law or
regulation, or any order, writ, injunction or decree of any court or
governmental authority or agency, or any agreement or instrument to which any of
the Obligors or any of their Subsidiaries is a party or by which any of them or
any of their Property is bound or to which any of them is subject, or constitute
a default under any such agreement or instrument, or (except for the Liens
created pursuant to the Security Documents) result in the creation or imposition
of any Lien upon any Property of any of the Obligor or any of their respective
Subsidiaries pursuant to the terms of any such agreement or instrument.

         8.05 Action. Each Obligor has all necessary corporate or partnership
power (as the case may be), authority and legal right to execute, deliver and
perform its obligations under each of the Basic Documents to which it is a
party; the execution, delivery and performance by each Obligor of each of the
Basic Documents to which it is a party have been duly authorized by all
necessary corporate or partnership action (as the case may be) on its part
(including, without limitation, any required shareholder or partnership
approvals); and this Agreement has been duly and validly executed and delivered
by each Obligor and constitutes, and each of the Notes and the other Basic
Documents to which it is a party when executed and delivered by such Obligor (in
the case of the Notes, for value) will constitute, its legal, valid and binding
obligation, enforceable against each Obligor in accordance with its terms.

         8.06 Approvals. No authorizations, approvals or consents of, and no
filings or registrations with, any governmental or regulatory authority or
agency, or any securities exchange, are necessary for the consummation of the
Acquisition or the execution, delivery or performance by any Obligor of the
Basic Documents to which it is a party or the execution, delivery or performance
by each Person party to any Acquisition Document, or for the legality, validity
or enforceability thereof.

         8.07 Legal Form. This Agreement and each other Basic Document is in
proper


                                      -50-
<PAGE>   51
legal form under the law of Mexico for the enforcement thereof against the
Obligors and, as the case may be, SLC Mexico under such law, and if this
Agreement and each other Basic Document were stated to be governed by such law,
they would constitute legal, valid and binding obligations of each Obligor and,
as the case may be, SLC Mexico under such law, enforceable in accordance with
their respective terms. All formalities required in Mexico for the validity and
enforceability of this Agreement and each other Basic Document (including,
without limitation, any necessary registration, recording or filing with any
court or other authority in Mexico (other than any such registration, recording
or filing of the Mortgage, which, on the date hereof will not be accomplished))
have been accomplished, and no Mexican Taxes are required to be paid and no
notarization is required, for the validity and enforceability thereof (other
than, upon any registration, recording or filing of a Mortgage pursuant to the
terms hereof, Mexican Taxes payable at such time).

         8.08 Ranking. This Agreement and each other Basic Document and the
obligations evidenced hereby and thereby are and will at all times be direct and
unconditional general obligations of each Obligor and rank and will at all times
rank in right of payment and otherwise at least pari passu with all other senior
unsecured Indebtedness of each Obligor, whether now existing or hereafter
outstanding.

         8.09 Taxes. Each of the Obligor, SLC Mexico and their respective
Subsidiaries have filed all material tax returns that are required to be filed
by them and have paid all taxes due pursuant to such returns or pursuant to any
assessment received by any of the Obligor, SLC Mexico or any of their respective
Subsidiaries. The charges, accruals and reserves on the books of the Obligors,
SLC Mexico and their respective Subsidiaries in respect of taxes and other
governmental charges are, in the opinion of the Obligors, adequate.

         8.10 Commercial Activity; Absence of Immunity. Each of the Company and
SLC Mexico is subject to civil and commercial law with respect to its
obligations under each of the Basic Documents to which it is a party. The
execution, delivery and performance by the Company and SLC Mexico of each Basic
Document to which it is a party constitute private and commercial acts rather
than public or governmental acts. None of the Company, SLC Mexico, nor any of
their respective Properties or revenues, is entitled to any right of immunity in
any jurisdiction from suit, court jurisdiction, judgment, attachment (whether
before or after judgment), set-off or execution of a judgment or from any other
legal process or remedy relating to the obligations of such Person under any of
the Basic Documents to which it is a party.

         8.11 Material Agreements and Liens. Schedule 8.11 hereto is a complete

included herein or therein or delivered pursuant hereto or thereto, when taken
as a whole do not contain any untrue statement of material fact or omit to state
any material fact necessary to make the statements herein or therein, in light
of the circumstances under which they were made, not misleading. All written
information furnished after the date hereof by the Obligors and their respective
Subsidiaries to the Agent and the Lenders in connection with this Agreement and
the other Basic Documents and the transactions contemplated hereby and thereby
will be true, complete and accurate in every material respect, or (in the case
of projections) based on reasonable estimates, on the date as of which such
information is stated or certified. There is no fact known to any Obligor that
could have a Material Adverse Effect that has not been disclosed herein, in the

         8.15 ERISA. As of the Closing Date, none of the Guarantors has any

reasonably be expected to have a Material Adverse Effect has occurred with
respect to any Plan and there is no lien outstanding under Section 412 of the
Code or Section 302 of ERISA with respect to any Obligor's assets. As of the

                                      -52-

material respects with the requirements of ERISA and the Code and plan documents
for any Employee Benefit Plan which has or could reasonably be expected to have
a Material Adverse Effect and are not in default (as defined in Section
4219(c)(5) of ERISA) with respect to payments to a Multiemployer Plan which has
or could reasonably be expected to have a Material Adverse Effect. None of the
Guarantors, nor any member of their respective ERISA Controlled Groups
(determined without reference to Section 414(m) or (o) of the Code, if
liabilities of entities in the Guarantors' ERISA Controlled Group solely by
reason of Section 414(m) or (o) could not result in liability to the Guarantors)

4201 or 4204 of ERISA which, individually or in the aggregate is in excess of
$5,000,000 or has or could reasonably be expected to have a Material Adverse
Effect. To the best knowledge of the Guarantors, no Multiemployer Plan is or is
likely to be disqualified for tax purposes, in reorganization (within the
meaning of Section 4241 of ERISA or Section 418 of the Code) or is insolvent (as
defined in Section 4245 of ERISA), which event would have a Material Adverse
Effect. No liability to the PBGC (other than required premium payments), the
Internal Revenue Service (with respect to an Employee Benefit Plan), any Plan or
any trust established under Section 4049 of ERISA has been, or is expected by
the Guarantors to be, incurred by the Guarantors (other than annual
contributions) which is in excess of $5,000,000 or would have a Material Adverse
Effect. Except as otherwise disclosed on Schedule 8.15 hereto, none of the
Guarantors has any contingent liability with respect to any post-retirement
benefits under any "welfare plan" (as defined in Section 3(1) of ERISA) or
withdrawal liability or exist fee or charge with respect to any "welfare plan"
(as defined in Section 3(1) of ERISA), other than liability for continuation
coverage under Part 6 of Title I of ERISA or state laws which require similar
continuation coverage for which the employee pays approximately the full cost of
coverage, and other than such liability that is both not more than $5,000,000
and that would not have a Material Adverse Effect. No lien under Section 412(n)
of the Code or 302(f) of ERISA or requirement to provide security under Section
401(a)(29) of the Code or Section 307 of ERISA has been or is reasonably
expected by the Guarantors to be imposed on the assets of the Guarantors. Except
as disclosed on Schedule 8.15 none of the Guarantors is a party to any
collective bargaining agreement. None of the Guarantors has engaged in any
transaction prohibited by Section 408 of ERISA or Section 4975 of the Code which
has a Material Adverse Effect. As of the Closing Date and throughout the term of
the Loan, none of the Guarantors is or will be an "employee benefit plan" as
defined in Section 3(3) of ERISA, which is subject to Title I of ERISA, and none
of the assets of the Guarantors will constitute "plan assets" of one or more
such plans for purposes of Title I of ERISA. As of the Closing Date and
throughout the term of the Loan, none of the Guarantors is or will be a
"governmental plan" within the meaning of Section 3(3) of ERISA and none of the
Guarantors will be subject to state statutes applicable to such Guarantors
regulating investments.

Subsidiaries has obtained all environmental, health and safety permits, licenses

shall provide to the Agent, within ten (10) days of the Agent's request, any
document, filing or correspondence relating to an Employee Benefit Plan which

if the events could result in Material Adverse Effect.

                  (b) None of the Guarantors shall engage in any transaction
which would cause any obligation, or action taken or to be taken, hereunder (or
the exercise by the Agent on behalf of the Lenders of any of its rights under
this Agreement or the other Basic Documents) to be a non-exempt (under a
statutory or administrative class exemption) prohibited transaction under ERISA

would subject Lender to liability for a violation of ERISA or such a state
statute.

                  (c) SLT and the Trust further covenant and agree to deliver to
the Agent such certifications or other evidence from time to time throughout the

plan" within the meaning of Section 3(3) of ERISA; (ii) none of the Guarantors

         Subsidiaries) an Environmental Claim that, in the judgment of the
         Majority Lenders is reasonably likely to be determined adversely to the
         applicable Obligor or Subsidiary, and the amount thereof (either
         individually or in the aggregate) is reasonably likely to have a
         Material Adverse Effect (insofar as such amount is payable by such
         Obligor or Subsidiary but after deducting any portion thereof that is
         reasonably expected to be paid by other creditworthy Persons jointly

other formalities of any kind, all of which are hereby expressly waived by each
Obligor; and (2) in the case of the occurrence of an Event of Default referred
to in clause (j) or (k) of this Section 10 with respect to any Obligor, the
Commitments shall automatically be terminated and the principal amount then
outstanding of, and the accrued interest on, the Loans and all other amounts
payable by the Obligors hereunder and under the Notes (including, without
limitation, any amounts payable under Section 5.04 hereof) shall automatically
become immediately due and payable without presentment, demand, protest or other
formalities of any kind, all of which are hereby expressly waived by each
Obligor; and (3) in the case of the occurrence of an Event of Default referred
to in clauses (a), (b), (c), (d), (e) (f), (g), (h), (i), (j), (k), (m), (n),
(p), (r) or (s), the Agent may, and if so requested by the Majority Lenders,
shall, cause the Mortgages to be registered with the applicable public registry
of property, at the expense of the Obligors, and the cost and expense associated
with such registration shall be for the account of the Obligors and shall

         Section 11. The Agent.

         11.01 Appointment, Powers and Immunities. Each Lender hereby
irrevocably appoints and authorizes the Agent to act as its agent hereunder and
under the other Basic Documents with such powers as are specifically delegated
to the Agent by the terms of this Agreement and of the other Basic Documents,
together with such other powers as are reasonably incidental thereto. The Agent
(which term as used in this sentence and in Section 11.05 and the first sentence
of Section 11.06 hereof shall include reference to its affiliates and its own
and its affiliates' officers, directors,


                                      -73-

expressly set forth in this Agreement and in the other Basic Documents, and
shall not by reason of this Agreement or any other Basic Document be a trustee
for any Lender; (b) shall not be responsible to the Lenders for any recitals,
statements, representations or warranties contained in this Agreement or in any
other Basic Document, or in any certificate or other document referred to or
provided for in, or received by any of them under, this Agreement or any other
Basic Document, or for the value, validity, effectiveness, genuineness,
enforceability or sufficiency of this Agreement, any Note or any other Basic
Document or any other document referred to or provided for herein or therein or
for any failure by the Company or any other Person to perform any of its
obligations hereunder or thereunder; (c) shall not be required to initiate or
conduct any litigation or collection proceedings hereunder or under any other
Basic Document; and (d) shall not be responsible for any action taken or omitted
to be taken by it hereunder or under any other Basic Document or under any other
document or instrument referred to or provided for herein or therein or in
connection herewith or therewith, except for its own gross negligence or willful
misconduct. The Agent may employ agents and attorneys-in-fact and shall not be
responsible for the negligence or misconduct of any such agents or
attorneys-in-fact selected by it in good faith. The Agent may deem and treat the
payee of any Note as the holder thereof for all purposes hereof unless and until
a notice of the assignment or transfer thereof shall have been filed with the
Agent.

         11.02 Reliance by Agent. The Agent shall be entitled to rely upon any
certification, notice or other communication (including, without limitation, any
thereof by telephone, facsimile, telex, telegram or cable) believed by it to be
genuine and correct and to have been signed or sent by or on behalf of the
proper Person or Persons, and upon advice and statements of legal counsel,
independent accountants and other experts selected by the Agent. As to any
matters not expressly provided for by this Agreement or any other Basic
Document, the Agent shall in all cases be fully protected in acting, or in
refraining from acting, hereunder or thereunder in accordance with instructions
given by the Majority Lenders or, if provided herein, in accordance with the
instructions given by all of the Lenders and such instructions of such Lenders
and any action taken or failure to act pursuant thereto shall be binding on all
of the Lenders.

         11.03 Defaults. The Agent shall not be deemed to have knowledge or
notice of the occurrence of a Default unless the Agent has received notice from
a Lender or the Company specifying such Default and stating that such notice is
a "Notice of Default". In the event that the Agent receives such a notice of the
occurrence of a Default, the Agent shall give prompt notice thereof to the
Lenders. The Agent shall (subject to Section 11.07 hereof) take such action with
respect to such Default as shall be directed by the Majority Lenders provided
that, unless and until the Agent shall have received such directions, the Agent
may (but shall not be obligated to) take such action, or refrain from taking
such action, with respect to such Default as it shall deem advisable in the best
interest of the Lenders except to the extent that this Agreement expressly
requires that such action be taken, or not be taken, only with the consent or
upon the authorization of the Majority Lenders or all of the Lenders.

and may exercise the same as though Bancomer, S.A. were not acting as the Agent,
and the term "Lender" or "Lenders" shall, unless the context otherwise
indicates, include Bancomer, S.A. in its individual capacity. Bancomer, S.A.
(and any successor acting as Agent) and its affiliates may (without having to
account therefor to any Lender) accept deposits from, lend money to, make
investments in and generally engage in any kind of banking or other business
with the Obligors (and any of their Subsidiaries or Affiliates) as if it were
not acting as the Agent, and Bancomer, S.A. and its affiliates may accept fees
and other consideration from the Obligors for services in connection with this
Agreement or otherwise without having to account for the same to the Lenders.

         11.05 Indemnification. The Lenders agree to indemnify the Agent (to the
extent not reimbursed under Section 12.03 hereof, but without limiting the
obligations of the Company under said Section 12.03) ratably in accordance with
the aggregate principal amount of the Loans held by the Lenders (or, if no Loans
are at the time outstanding, ratably in accordance with their respective
Commitments), for any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind and nature whatsoever that may be imposed on, incurred by or asserted
against the Agent (including by any Lender) arising out of or by reason of any
investigation in or in any way relating to or arising out of this Agreement or
any other Basic Document or any other documents contemplated by or referred to
herein or therein or the transactions contemplated hereby or thereby (including,
without limitation, the costs and expenses that the Company is obligated to pay
under Section 12.03 hereof but excluding, unless a Default has occurred and is
continuing, normal administrative costs and expenses incident to the performance
of its agency duties hereunder) or the enforcement of any of the terms hereof or
thereof or of any such other documents, provided that no Lender shall be liable
for any of the foregoing to the extent they arise from the gross negligence or
willful misconduct of the party to be indemnified.

         11.06 Non-Reliance on Agent and Other Lenders. Each Lender agrees that
it has, independently and without reliance on the Agent or any other Lender, and
based on such documents and information as it has deemed appropriate, made its
own credit analysis of the Parent and its Subsidiaries and decision to enter
into this Agreement and that it will, independently and without reliance upon
the Agent or any other Lender, and based on such documents and information as it
shall deem appropriate at the time, continue to make its own analysis and
decisions in taking or not taking action under this Agreement or under any other
Basic Document. The Agent shall not be required to keep itself informed as to
the performance or observance by any Obligor of this Agreement or any of the
other Basic Documents or any other document referred to or provided for herein
or therein or to inspect the Properties or books of the Parent or any of its
Subsidiaries. Except for notices, reports and other documents and information


                                      -75-
<PAGE>   76
expressly required to be furnished to the Lenders by the Agent hereunder or
under the Security Documents, the Agent shall not have any duty or
responsibility to provide any Lender with any credit or other information
concerning the affairs, financial condition or business of the Parent or any of
its Subsidiaries (or any of their affiliates) that may come into the possession
of the Agent or any of its affiliates.

         11.07 Failure to Act. Except for action expressly required of the Agent
hereunder and under the other Basic Documents, the Agent shall in all cases be
fully justified in failing or refusing to act hereunder and thereunder unless it
shall receive further assurances to its satisfaction from the Lenders of their
indemnification obligations under Section 11.05 hereof against any and all
liability and expense that may be incurred by it by reason of taking or
continuing to take any such action.

         11.08 Resignation of Agent. Subject to the appointment and acceptance
of a successor Agent as provided below, the Agent may resign at any time by
giving notice thereof to the Lenders and the Company. Upon any such resignation,
the Majority Lenders shall have the right to appoint a successor Agent. If no
successor Agent shall have been so appointed by the Majority Lenders and shall
have accepted such appointment within 30 days after the retiring Agent's giving
of notice of resignation, then the retiring Agent may, on behalf of the Lenders,
appoint a successor Agent, that shall be a financial institution that has an
office in New York, New York. Upon the acceptance of any appointment as Agent
hereunder by a successor Agent, such successor Agent shall thereupon succeed to
and become vested with all the rights, powers, privileges and duties of the
retiring Agent, and the retiring Agent shall be discharged from its duties and
obligations hereunder. After any retiring Agent's resignation hereunder as
Agent, the provisions of this Section 11 shall continue in effect for its
benefit in respect of any actions taken or omitted to be taken by it while it
was acting as the Agent.

         11.09 Consents under Other Basic Documents. Except as otherwise
provided in Section 12.05 hereof with respect to this Agreement, the Agent may,
with the prior consent of the Majority Lenders (but not otherwise), consent to
any modification, supplement or waiver under any of the Basic Documents,
provided that, without the prior consent of each Lender, the Agent shall not
(except as provided herein or in the Security Documents) release any collateral
or otherwise terminate any Lien under any Basic Document providing for
collateral security, or agree to additional obligations being secured by such
collateral security, except that no such consent shall be required, and the
Agent is hereby authorized, to release any Lien covering Property that is the
subject of a disposition of Property permitted hereunder or to which the
Majority Lenders have consented.

         Section 12. Miscellaneous.

         12.01 Waiver. No failure on the part of the Agent or any Lender to
exercise and


                                      -76-
<PAGE>   77
no delay in exercising, and no course of dealing with respect to, any right,
power or privilege under this Agreement or any Note shall operate as a waiver
thereof, nor shall any single or partial exercise of any right, power or
privilege under this Agreement or any Note preclude any other or further
exercise thereof or the exercise of any other right, power or privilege. The

provided by law.

<PAGE>   78

         or therein and all costs, expenses, taxes, assessments and other
         charges incurred in connection with any filing, registration, recording
         or perfection of any security interest contemplated by any Basic
         Document or any other document referred to therein.

         12.04 Indemnification. Each Obligor hereby agrees to indemnify the
Agent and each Lender and their respective directors, officers, employees,
attorneys and agents from, and hold each of them harmless against, any and all
losses, liabilities, claims, damages or expenses incurred by any of them arising

relating to the Loans hereunder or any actual or proposed use by the Company of

         12.05 Amendments, Etc. Except as otherwise expressly provided in this
Agreement, any provision of this Agreement may be modified or supplemented only
by an instrument in writing signed by the Company, the Agent and the Majority
Lenders, or by the Company and the Agent acting with the consent of the Majority
Lenders, and any provision of this Agreement may be waived by the Majority
Lenders or by the Agent acting with the consent of the Majority Lenders;
provided that:

                  (a) no modification, supplement or waiver shall, unless by an
         instrument signed by all of the affected Lenders or by the Agent acting
         with the consent of all of the affected Lenders: (i) increase, or
         extend the term of any of the Commitments, or extend the time or waive
         any requirement for the reduction or termination of any of the
         Commitments, (ii) extend the date fixed for the payment of principal of

<PAGE>   79
                  (c) any modification or supplement of Section 6 hereof shall
         require the consent of each Guarantor.

         12.06 Successors and Assigns. This Agreement shall be binding upon and
inure to the benefit of the parties hereto and their respective successors and
permitted assigns.

         12.07 Assignments and Participations.

         (a) No Obligor may assign any of its rights or obligations hereunder or
under the Notes without the prior consent of all of the Lenders and the Agent.

         (b) Each Lender may assign any of its Loan and its Note with the
consent of the Agent and the Company (which consent shall not be unreasonably
withheld); provided that (i) any assignment by a Lender to another Lender shall
not require the Agent's consent; (ii) any partial assignment shall be in an
amount at least equal to U.S.$10,000,000; (iii) each such assignment by a Lender
of its Loan and its Note shall be made in such manner so that the same portion
of its Loans and the Note is assigned to the respective assignee; and (iv) no
such assignment may be made except to a financial institution that is (a)
registered with the Mexican Secretaria de Hacienda y Credito Publico for
purposes of Article 154, Section I of the Mexican income tax law (Ley de
Impuesto Sobre la Renta) and (b) a resident for tax purposes of a jurisdiction
with which Mexico has in effect a treaty for the avoidance of double taxation.
Upon execution and delivery by the assignee to the Company and the Agent of an
instrument in writing pursuant to which such assignee agrees to become a
"Lender" hereunder (if not already a Lender) having the Loan specified in such
instrument, and upon notice thereof to the Company and the Agent, the assignee
shall have, to the extent of such assignment, the obligations, rights and
benefits of a Lender hereunder holding the Loan (or portions thereof) assigned
to it (in addition to the Loan, if any, theretofore held by such assignee). Upon
each such assignment the assigning Lender shall pay the Agent an assignment fee
of $3,000.

         (c) A Lender may sell or agree to sell to one or more other Persons a
participation in all or any part of any Loan held by it, in which event each
purchaser of a participation (a "Participant") (which participation may not be
made to a financial institution that is not (a) registered with the Mexican
Secretaria de Hacienda y Credito Publico for purposes of Article 154, Section I
of the Mexican income tax law (Ley de Impuesto Sobre la Renta) and (b) a
resident for tax purposes of a jurisdiction with which Mexico has in effect a
treaty for the avoidance of double taxation) shall be entitled to the rights and
benefits of the provisions of Section 9.01(g) hereof with respect to its
participation in such Loan as if (and the Company shall be directly obligated to
such Participant under such provisions as if) such Participant were a "Lender"
for purposes of said Section, but, except as otherwise provided in Section
4.07(c) hereof, shall not have any other rights or benefits under this Agreement
or any Note or any other Basic


                                      -79-
<PAGE>   80
Document (the Participant's rights against such Lender in respect of such
participation to be those set forth in the agreements executed by such Lender in
favor of the Participant). All amounts payable by the Company to any Lender
under Section 5 hereof in respect of a Loan held by it, shall be determined as
if such Lender had not sold or agreed to sell any participations in such Loan
and as if such Lender were funding each of such Loan in the same way that it is
funding the portion of such Loan in which no participations have been sold. In
no event shall a Lender that sells a participation agree with the Participant to
take or refrain from taking any action hereunder or under any other Basic
Document except that such Lender may agree with the Participant that it will
not, without the consent of the Participant, agree to (i)) extend the date fixed
for the payment of principal of or interest on the Loan or any portion of any
fee hereunder payable to the Participant, (ii) reduce the amount of any such
payment of principal, (iii) reduce the rate at which interest is payable
thereon, or any fee hereunder payable to the Participant, to a level below the
rate at which the Participant is entitled to receive such interest or fee, (iv)
alter the rights or obligations of the Company to prepay the Loans or (v)
consent to any modification, supplement or waiver hereof or of any of the other
Basic Documents to the extent that the same, under Section 11.09 or 12.05
hereof, requires the consent of each Lender.

         (d) In addition to the assignments and participations permitted under
the foregoing provisions of this Section 12.07, any Lender may (without notice
to the Company, the Agent or any other Lender and without payment of any fee)
(i) assign and pledge all or any portion of its Loan and its Note to any Federal
Reserve Bank as collateral security pursuant to Regulation A and any Operating
Circular issued by such Federal Reserve Bank and (ii) assign all or any portion
of its rights under this Agreement and its Loan and its Note to an affiliate. No
such assignment shall release the assigning Lender from its obligations
hereunder.

         (e) A Lender may furnish any information concerning the Obligors in the
possession of such Lender from time to time to assignees and participants
(including prospective assignees and participants).

         (f) Anything in this Section 12.07 to the contrary notwithstanding, no
Lender may assign or participate any interest in any Loan held by it hereunder
to the Guarantors, the Company or any of their Affiliates or Subsidiaries
without the prior consent of each Lender.

         12.08 Survival. The obligations of the Company under Sections 5.01,
5.03, 5.04,12.03 and 12.04 hereof, the obligations of each Guarantor under
Section 6.03 hereof, and the obligations of the Lenders under Section 11.05
hereof shall survive the repayment of the Loans and the termination of the
Commitments. In addition, each representation and warranty made, or deemed to be
made by a notice of any Loan, herein or pursuant hereto shall survive the making
of such representation and warranty, and no Lender shall be deemed to have
waived, by reason of making any Loan, any Default that may arise by reason of
such representation or warranty proving to have


                                      -80-
<PAGE>   81
been false or misleading, notwithstanding that such Lender or the Agent may have
had notice or knowledge or reason to believe that such representation or
warranty was false or misleading at the time such Loan was made.

         12.09 Captions. The table of contents and captions and section headings
appearing herein are included solely for convenience of reference and are not
intended to affect the interpretation of any provision of this Agreement.

         12.10 Counterparts. This Agreement may be executed in any number of
counterparts, all of which taken together shall constitute one and the same
instrument and any of the parties hereto may execute this Agreement by signing
any such counterpart.

         12.11 Judgment Currency. This is an international loan transaction in
which the specification of Dollars and payment in New York City is of the
essence, and the obligations of the Obligors under this Agreement to make
payment to (or for the account of) a Lender in Dollars shall not be discharged
or satisfied by any tender or recovery pursuant to any judgment expressed in or
converted into any other currency or in another place except to the extent that
such tender or recovery results in the effective receipt by such Lender in New
York City of the full amount of Dollars payable to such Lender under this
Agreement. If for the purpose of obtaining judgment in any court it is necessary
to convert a sum due hereunder in Dollars into another currency (in this Section
12.11 called the "judgment currency"), the rate of exchange that shall be
applied shall be that at which in accordance with normal banking procedures the
Agent could purchase such Dollars at its New York City office with the judgment
currency on the Business Day next preceding the day on which such judgment is
rendered. The obligation of the Obligors in respect of any such sum due from it
to the Agent or any Lender hereunder or under any Basic Document (in this
Section 12.11 called an "Entitled Person") shall, notwithstanding the rate of
exchange actually applied in rendering such judgment, be discharged only to the
extent that on the Business Day following receipt by such Entitled Person of any
sum adjudged to be due hereunder in the judgment currency such Entitled Person
may in accordance with normal banking procedures purchase and transfer Dollars
to New York City with the amount of the judgment currency so adjudged to be due;
and each of the Obligors hereby, as a separate obligation and notwithstanding
any such judgment, agrees to indemnify such Entitled Person against, and to pay
such Entitled Person on demand, in Dollars, the amount (if any) by which the sum
originally due to such Entitled Person in Dollars hereunder exceeds the amount
of the Dollars so purchased and transferred.

         12.12 Governing Law. Each of the parties hereto agrees that, pursuant
to New York State General Obligations Law Section 5-1401, this Agreement shall
be governed by, and construed in accordance with, the law of the State of New
York, United States of America.

         12.13 Jurisdiction; Service of Process; Venue.


                                      -81-
<PAGE>   82
         (a) Each of the parties hereto agrees that any suit, action or
proceeding with respect to this Agreement, any Note, any other Basic Document or
any judgment entered by any court in respect of any thereof may be brought in
the Supreme Court of the State of New York, County of New York or in the United
States District Court for the Southern District of New York, as the party
commencing such suit, action or proceeding may elect in its sole discretion; and
each of the parties hereto hereby irrevocably submits to the jurisdiction of
such courts for the purpose of any suit, action, proceeding or judgment.

         (b) Each Obligor hereby agrees that service of all writs, process and
summonses in any such suit, action or proceeding brought in the State of New
York may be made upon CT Corporation, presently located at 1633 Broadway, New
York, New York 10019, U.S.A. (the "Process Agent"), and each Obligor hereby
confirms and agrees that the Process Agent has been duly and irrevocably
appointed as its agent and true and lawful attorney-in-fact in its name, place
and stead to accept such service of any and all such writs, process and
summonses, and agrees that the failure of the Process Agent to give any notice
of any such service of process to such Obligor shall not impair or affect the
validity of such service or of any judgment based thereon. Each Obligor hereby
further irrevocably consents to the service of process in any suit, action or
proceeding in said courts by the mailing thereof by the Agent or any Lender by
registered or certified mail, postage prepaid, at its address set forth beneath
its signature hereto.

         (c) Nothing herein shall in any way be deemed to limit the ability of
the Agent or any Lender to serve any such writs, process or summonses in any
other manner permitted by applicable law or to obtain jurisdiction over any
Obligor in such other jurisdictions, and in such manner, as may be permitted by
applicable law.

         (d) Each Obligor hereby irrevocably waives any objection that it may
now or hereafter have to the laying of the venue of any suit, action or
proceeding arising out of or relating to this Agreement, the Notes or any other
Basic Document brought in the Supreme Court of the State of New York, County of
New York or in the United States District Court for the Southern District of New
York, and hereby further irrevocably waives any claim that any such suit, action
or proceeding brought in any such court has been brought in an inconvenient
forum.

         (e) Each Obligor irrevocably waives, to the fullest extent permitted by
applicable law, any claim that any action or proceeding commenced by the Agent
or any Lender relating in any way to this Agreement should be dismissed or
stayed by reason, or pending the resolution, of any action or proceeding
commenced by any Obligor relating in any way to this Agreement whether or not
commenced earlier. To the fullest extent permitted by applicable law, the
Obligors shall take all measures necessary for any such action or proceeding
commenced by the Agent or any Lender to proceed to judgment prior to the entry
of judgment in any such action or proceeding commenced


                                      -82-
<PAGE>   83
by any Obligor.

         12.14 No Immunity. To the extent that any Obligor may be or become
entitled, in any jurisdiction in which judicial proceedings may at any time be
commenced with respect to this Agreement or any other Basic Document, to claim
for itself or its Property any immunity from suit, court jurisdiction,
attachment prior to judgment, attachment in aid of execution of a judgment,
execution of a judgment or from any other legal process or remedy relating to
its obligations under this Agreement or any other Basic Document, and to the
extent that in any such jurisdiction there may be attributed such an immunity
(whether or not claimed), each of the Obligors hereby irrevocably agrees not to
claim and hereby irrevocably waives such immunity to the fullest extent
permitted by the laws of such jurisdiction and agrees that the foregoing waiver
shall have the fullest extent permitted under the Foreign Sovereign Immunities
Act of 1976 of the United States of America and is intended to be irrevocable
for purposes of such Act.

         12.15 Waiver of Jury Trial. EACH OF THE OBLIGORS, THE AGENT AND THE
LENDERS HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE
LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF
OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

         12.16 The Trustee of the Trust. The Lenders each acknowledge and agree
that the name "Starwood Lodging Trust" is a designation of the real estate
investment trust and its trustees (as trustees but not personally) under a
Declaration of Trust dated August 25, 1969, as amended and restated as of June
6, 1988, as further amended on February 1, 1995 and as further amended on June
19, 1995 and as the same may be further amended from time to time, and all
persons dealing with the Trust shall look solely to the Trust's assets for the
enforcement of any claims against the Trust, as the trustees, officers, agents
and security holders of the Trust assume no personal liability for obligations
entered into on behalf of the Trust, and their respective individual assets
shall not be subject to the claims of any person relating to such obligations.
The foregoing shall govern all direct and indirect obligations of the Trust
under the Basic Documents.

         12.17 Use of English Language. This Agreement has been negotiated and
executed in the English language. All certificates, reports, notices and other

Agreement, and absent manifest error, control the meaning of the matters set
forth therein.
