         THIS AGREEMENT AND DECLARATION OF TRUST (the "Agreement") is made as
of the 6th day of March, 1997, by and among Lomas Financial Corporation. Inc.,
a Delaware corporation and a Debtor and a Debtor-in-possession ("LFC"), Lomas
Information Systems. Inc., a Nevada corporation and a Debtor and a
Debtor-in-possession ("LIS"), Lomas Administrative Services, Inc., a Nevada
corporation and a Debtor and a Debtor-in-possession ("LAS"), Siena Holdings,
Inc., a Delaware corporation ("Reorganized LFC"), Siena Information Services,
Inc., a Nevada corporation ("Reorganized LIS"), and Lomas Mortgage USA, Inc., a
Connecticut corporation and a Debtor and a Debtor-in-possession ("LMUSA"),

Esq. and Martin J. Bienenstock, Esq., as Trustees for the LMUSA Litigation
Trust, and Martin R. Pollner, Esq., as the Trustee hereunder (as defined
below).

                                    RECITALS

         A.      LFC, and its subsidiaries LMUSA, LIS and LAS (the "Debtors"),
filed voluntary petitions under Chapter 11 of the United States Bankruptcy Code
on or about October 10, 1995.

         The Joint Chapter 11 Plan for LFC, LIS and LAS, dated April 8, 1996,
(the "LFC Plan"), a copy of which is attached hereto as Exhibit A, was filed
with the Bankruptcy Court in the proceeding captioned In re Lomas Financial
Corporation, Lomas Information Systems, Inc. and Lomas Administrative
Services, Inc., Debtors, Case Nos. 95-1235, 1237 and 1238 (PJW).

         The LMUSA Chapter 11 Plan, dated April 8, 1996, (the "LMUSA Plan"), a
copy of which is attached hereto as Exhibit B, was filed with the Bankruptcy
Court in the proceeding captioned In re Lomas Mortgage USA, Inc., Debtor, Case
No. 95-1236 (PJW). (The LFC Plan and the LMUSA Plan are collectively the
"Plans".)

         B.      The LFC Plan, as modified by certain modifications approved by
the Bankruptcy Court and attached hereto as Exhibit C, was confirmed by order
of the Bankruptcy Court dated October 4, 1996 (the "LFC Order").

         The LMUSA Plan, as modified by certain modifications approved by the
Bankruptcy Court and attached hereto as Exhibit D, was confirmed by order of
the Bankruptcy Court dated October 1, 1996 (the "LMUSA Order").

         Pursuant to the LMUSA Plan, the LMUSA Litigation Trust (the "Original
LMUSA Litigation Trust") was established. Neil B. Glassman, Esq. and Martin J.
Bienenstock, Esq. were named trustees of the Original LMUSA Litigation Trust.
Pursuant to the LMUSA Litigation Trust

<PAGE>   6
Agreement dated as of October 1, 1996, a copy of which is attached as Exhibit
E, certain assets of LMUSA were deemed transferred to the Original LMUSA
Litigation Trust.

         Pursuant to paragraph 21 of the LMUSA Order, the assets of the
Original LMUSA Litigation Trust are deemed transferred to the LFC/LMUSA Trust.

         The LFC Plan also provided for a litigation trust to be created solely
for certain assets of LFC, LIS, and LAS; however, pursuant to paragraph 21 of
the LFC Order, those assets will instead be transferred directly to the
LFC/LMUSA Trust.

         C.      On February 21,1997, the Bankruptcy Court approved the
Agreement Between LMU Statutory Creditors' Committee and LFC Statutory
Creditors' Committee in Respect of Intercompany Claims (the "Intercreditor
Agreement"), a copy of which is attached as Exhibit F. Pursuant to and subject
to the express terms of the Intercreditor Agreement, the Plans, the LFC Order,
and the LMUSA Order, this LFC/LMUSA Trust (the "Trust" or the "LFC/LMUSA
Trust") is hereby established.

         D.      Pursuant to the terms of the Intercreditor Agreement, the LFC
Order, and the LMUSA Order, each of LFC, LIS, LAS, LMUSA, and the Original
LUMSA Litigation Trust shall be deemed to have transferred and assigned to the
LFC/LMUSA Trust, the assets specified in paragraph 19 of the LFC Order and
paragraph 20 of the LMUSA Order, namely all claims, rights, or causes of action
that constitute or constituted property of any of the Estates or of the
Debtors, whether arising under the Bankruptcy Code or under nonbankruptcy law
(including all books, records, privileges and defenses relating thereto),
including, without limitation, all rights of setoff and rights under Section
502(d) of the Bankruptcy Code and all avoiding power actions, including,
without limitation, under Sections 544, 545, 547, 548, 549, 550 and 553 of the
Bankruptcy Code or under applicable nonbankruptcy law as applied through
Section 544(b) of the Bankruptcy Code, other than Intercompany Claims and other
than any asset or interest owned or held by any of the Debtors as reflected in
its Confirmation Date balance sheet and otherwise reflected in LFC's financial
statements and accompanying notes, such as notes, debentures, nursing home
contracts, other contracts, excess benefit plan assets, MSP/rabbi trust fund
assets, stocks or other securities or partnership interests. Notwithstanding
the foregoing, as the Plans further provide, the Debtors shall retain their
rights of setoff and their rights under Section 502(d) of the Bankruptcy Code
to the extent necessary to defend against a Claim by any person against whom
claims, rights or causes of action are assigned to the LFC/LMUSA Trust pursuant
to the preceding sentence. The Original LMUSA Litigation Trust has not been
funded. In addition, the Intercreditor Agreement, the LFC Order, and the LMUSA
Order provide that the LFC Administrative Beneficiary and the Reorganized LMUSA
(or the Original LMUSA Litigation Trust) shall transfer to the LFC/LMUSA Trust
such amount as the respective Creditors' Committees shall have specified in the
Intercreditor Agreement, namely $3,000,000 and $2,000,000, as an initial
Expense Reserve.

         E.      The Intercreditor Agreement and the LFC Order and LMUSA Order
provide that the Trustee will be responsible for pursuing, as appropriate, the
claims and causes of action assigned to the Trust through litigation or, if
appropriate, settlement and distribution of, pursuant to SECTION 4.3





                                      -2-

and 4.4, any Net Proceeds of such litigation or settlement to (i) Reorganized
LMUSA for distribution to holders of Allowed LMUSA Class 3 Claims or (ii) to
the LFC Administrative Beneficiary for eventual distribution to the holders of
Allowed LFC Class 3 Claims, Allowed LIS Class 3 Claims or Allowed LAS Class 3
Claims in accordance with SECTION 7.5 of the LFC Plan. The Plans further
provide that the Trustee will be discharged from any further distribution
responsibility after distribution to the LFC Administrative Beneficiary or
Reorganized LMUSA, who will be responsible for further distribution of any such
Net Proceeds. The LFC Administrative Beneficiary will be discharged from any
further distribution responsibility after distribution to Reorganized LFC,
Reorganized LIS, and Reorganized LAS.

         F.      The Trust shall be deemed not to be any of the Debtors or a
successor to any of the Debtors, but only the assignee of the assets
transferred to the Trust.

         G.      It is desired that the mechanism for payment of funds
constituting proceeds of the Trust Assets be specified and that the Trustee's
rights, powers and duties with respect to the Trust created hereby be
established.

         H.      The Trustee shall be authorized to do and perform such acts,
to execute and deliver such bills of sale, instruments of transfer and other
documents and to engage the services of such agents, attorneys, accountants,
appraisers, consultants and other persons as he may deem necessary or advisable
in order to carry out the purposes of the Trust created hereby.

         2.1 Declaration of Trust. Pursuant to the Plans, the Intercreditor
Agreement, and paragraph 21 of the LFC Order and the LMUSA Order, on the
Effective Date, each of the Debtors transferred the Initial Trust Assets to the

Agreement and of the Plans. Upon the transfer of the Trust Assets, the Debtor
shall retain no interest in such assets. This Trust is irrevocable. The
transfers shall be treated for federal income tax purposes, as transfers of the
assets to the LFC Administrative Beneficiary and the Reorganized LMUSA, on
behalf of the creditors of the Debtor, Pro Rata, and deemed transfers by them
to the Trust.

         2.2     No Additional Beneficiaries. The Trust shall be solely for the
benefit of the LFC Administrative Beneficiary and Reorganized LMUSA as trustees
for the benefit of certain of the creditors of the Debtors as set forth in the
Plans.

         2.3     Property In Trust. The Trustee shall hold the legal title to
all property at any time constituting a part of the Trust Assets and hereby
declares that he shall hold such property in trust to be administered and
disposed of pursuant to the terms of this Agreement for the benefit of the LFC
Administrative Beneficiary and Reorganized LMUSA as trustee for the benefit of
certain of the creditors of the Debtors pursuant to the terms of the Plan. The
Trustee is further authorized to make disbursements and payments from the Trust
in accordance with the provisions hereof.

         2.4     Creation of Expense Fund. The transfer of the Expense Fund to
the Trustee, in trust, is subject to the terms of this SECTION 2.4. The Expense
Fund is to be used solely to cover the expenses of the Trust as set forth in
SECTION 4.1. Neither the LFC Administrative Beneficiary, Reorganized LMUSA, nor
any of their subsidiaries, affiliates, agents, or assigns shall have any
obligation to pay any of the expenses of the Trust, other than the obligation
to transfer the Expense Fund to the Trust. The LFC Administrative Beneficiary

termination and winding up of the Trust pursuant to ARTICLE 3, any amounts
remaining in the Expense Fund as set forth in SECTION 4.4.

         2.5     Purpose of Trust. The sole purpose of this Trust is to
liquidate the Trust Assets in a manner calculated to conserve and protect the
value of the Trust Assets and to liquidate and distribute such assets to the
LFC Administrative Beneficiary and Reorganized LMUSA, as trustee, in as prompt
and orderly a fashion as possible after the payment of, or provision for,
expenses and liabilities. The Plan further provides that the LFC Administrative
Beneficiary will be responsible for distribution of any such Net Proceeds to
the holders of Allowed LFC Class 3 Claims, Allowed LIS Class 3 Claims or
Allowed LAS Class 3 Claims in accordance with SECTION 7.5 of the LFC Plan. The
Trustee shall report the Trust for Federal income tax purposes as a
pass-through grantor trust or as may be otherwise required or permitted under
applicable law. Pursuant to this express purpose, and subject to the provisions
of ARTICLE 5, the Trustee is hereby authorized and directed to take all
reasonable and necessary action to hold, conserve, and protect the Trust Assets
and to collect on, sell, or otherwise liquidate or dispose of the Trust Assets,
and to distribute the Net Proceeds of such disposition in as prompt, efficient
and orderly a fashion as possible in accordance with the provisions of ARTICLE
4.

         2.6     Income Tax Status. Consistent with Revenue Procedure 94-45,
1994-28 I.R.B.124, the Trust shall be treated as a liquidating trust pursuant
to Treasury Regulation Section 301.7701-4(d) and as a grantor trust pursuant to
Sections 671-677 of the Internal Revenue Code





                                      -6-

                                      LFC/LMUSA JOINT LITIGATION TRUST AGREEMENT

owned and established by the Debtor to satisfy the claims of its creditors. Any
items of income, deduction and credit loss of the Trust shall be allocated, for
federal income tax purposes, to the LFC Administrative Beneficiary and
Reorganized LMUSA. Pro Rata, on behalf of the creditors of the Debtors,
provided, however, that items of income (or deduction) attributable to sources
the distributions from which (or the expenses of which) are solely to the LFC
Administrative Beneficiary should be allocated solely to the LFC Administrative
Beneficiary on behalf of the appropriate LFC creditors. The income of the Trust
will be treated as subject to tax on a current basis to such beneficiaries.

         2.7     No Reversion to the LFC Administrative Beneficiary and
Reorganized LMUSA. In no event shall any part of the Trust Assets revert to or
be distributed to the LFC Administrative Beneficiary or Reorganized LMUSA
except in their capacities as trustees for the benefit of certain creditors
pursuant to the Plans.

         2.8     Instruments of Further Assurance: Information. The Debtors and
such persons as shall have the right and power after the Effective Date, upon
reasonable request of the Trustee, shall execute, acknowledge and deliver such
further instruments and do such further acts as may be necessary or proper to
effectively carry out the purposes of this Agreement, to transfer any property
intended to be conveyed hereby, and to vest in the Trustee, his successors and
assigns, the estate, powers, instruments or funds in trust hereunder.

                       DURATION AND TERMINATION OF TRUST

         3.1     Duration. The existence of this Trust shall terminate five
years from the date hereof, unless an earlier termination is required by the
applicable laws of the State of Delaware, or by the action of the LFC
Administrative Beneficiary and Reorganized LMUSA as provided in ARTICLE 8 or
unless earlier terminated by the distribution of all of the Trust Assets as
provided in SECTION 4.4. Notwithstanding the foregoing, in the event the
Trustee shall have been unable after reasonable efforts to settle or litigate
to a conclusion all causes of action included in the Trust Assets within the
first four years of the initial five-year term of the Trust Agreement, the
Trustee shall have the right to ask the court to extend the term of the Trust
for successive one-year renewal terms until all such causes of action have been
settled or litigated to a conclusion in fulfillment of the purposes of the
Trust. Pursuant to Revenue Procedure 94-45, 1994-28 I.R.B. 124, each such
extension must be approved by the Court within six months of the extended term.

         3.2     Continuance of Trust for Winding Up: Accounting. (a) After the
termination of the Trust and for the purpose of liquidating and winding up its
affairs, the Trustee shall continue to act as such until all duties have been
fully performed. Upon distribution of all of the Trust Assets, the Trustee
shall hold the books, records and files delivered to or created by the Trustee
for a period of four years. At the Trustee's discretion, all of such records
and documents may be destroyed at any time after four years from the
distribution of all of the Trust Assets. Except as otherwise specifically





                                      -7-

provided herein, upon the distribution of all of the Trust Assets, the Trustee
shall have no further duties or obligations hereunder except to account as
provided in SECTIONS 4.5 and 4.6. In the event that the Trustees have qualified
the Trust as a Delaware business trust in accordance with SECTION 10.1, upon
the completion of winding up and after termination of the Trust, the Trustees
shall file a certificate of cancellation in accordance with 12 Del. C. Section
3810(D).

         (b)     On the termination of the Trust, the Trustee has the authority
to apply to the Bankruptcy Court for any and all orders approving his
accounting for any of his actions as Trustee and discharging him from any and
all liability for acting as Trustee under this Trust.

                                   ARTICLE 4

                         ADMINISTRATION OF TRUST ESTATE

         4.1     Expense Reserve. On the Effective Date, the Trustee shall
establish the Expense Reserve for the payment of all expenses, debts, charges,
liabilities and obligations with respect to the Trust, including, without
limitation, (a) all costs and expenses, including those of professionals
retained by the Trustee, incurred in connection with any litigation, (b)
Trustee's fees, (c) all costs and expenses incurred in connection with
indemnifying the Trustee pursuant to SECTION 6.4, (d) all fees and expenses,
including those of professionals and other agents and employees retained by the
Trustee, incurred in connection with the performance of the Trustee's duties
and obligations including, without limitation, fees incurred in connection with
holding, collecting on, liquidating or otherwise disposing of the Trust Assets,
secretarial and office expenses, all applicable taxes and all expenses of
distribution and (e) all fees and expenses, including those of professionals
and other agents and employees retained by the Trustee, incurred in connection
with the winding up of the Trust pursuant to ARTICLE 3. The amount of the
Expense Reserve shall initially be the $5,000,000 Expense Fund received by the
Trustee pursuant to the terms of SECTIONS 2.1 and 2.4 less $ 1,000,000 which
shall be held in reserve pursuant to the terms of SECTION 4.2 (the
"Supplemental Reserve"). Thereafter, the Expense Reserve shall be funded out of
the proceeds of the Trust Assets as provided in SECTION 4.2 and the
Supplemental Reserve to the extent necessary and available. Upon the collection
of net proceeds from Recoveries in an amount equal to $1 million in the
aggregate, the Supplemental Reserve shall be distributed to the Beneficiaries,
as provided in Section 4.3; provided, however, that the Trustee shall not be
entitled to a percentage commission under Section 7.1 hereof upon the release
of the Supplemental Reserve. Any remaining balance in the Expense Reserve,
after the payment of all expenses, debts, charges, liabilities and obligations
intended to be paid therefrom, shall be distributed to the LFC Administrative
Beneficiary or Reorganized LMUSA, as trustees, as provided in SECTIONS 4.3 and
4.4. Any monies deposited in the Expense Reserve shall be invested in
interest-bearing deposits or investments that satisfy the requirements of
SECTION 5.1 and the interest earned thereon shall be credited to the Expense
Reserve.

         4.2     Increase of Expense Reserve Using Trust Assets. To the extent
the Trustee in his discretion determines that the amount of funds in the
Expense Reserve is at any time or may become insufficient, the Trustee, in his
discretion and judgment, may from time to time make additional





                                      -8-

                                      LFC/LMUSA JOINT LITIGATION TRUST AGREEMENT
<PAGE>   13
contributions to the Expense Reserve out of the Trust Assets or Supplemental
Reserve, for such reasonable amount or amounts as the Trustee in his discretion
and judgment may determine to be necessary or advisable to meet unliquidated or
contingent liabilities of the Trust. In no event shall the Trustee be required
to use his personal funds or assets for such purposes.

         4.3     Interim Distributions.

                 (a)(i)   Pursuant to Paragraph 13(i) of the Intercreditor
         Agreement, sixty percent (60%) of the Net Proceeds of all Recoveries
         shall be transferred to the LFC Administrative Beneficiary, and 40% of
         the Net Proceeds of all Recoveries shall be paid to Reorganized LMUSA,
         regardless of whether LFC, LIS, LAS or LMU owned the claims; provided,
         however, that 100% of the proceeds of claims for any nonfeasance or
         misfeasance in the creation of, or the administration or potential
         utilization of the proceeds of, the Rabbi Trusts shall belong solely
         to LFC. If a recovery from a third party results in the third party
         having an allowed claim against either LFC or LMU or their
         subsidiaries, the 60:40 allocation set forth above shall be determined
         after subtracting the amount LFC or LMU or their respective
         subsidiaries must distribute in respect of the allowed claim and
         paying the amount of such distribution to the entity that must make
         the distribution.

                 (ii) Pursuant to Paragraph 13.1 of the Intercreditor
         Agreement, 100% of the costs of pursuing claims for nonfeasance or
         misfeasance in the creation of, or the administration or potential
         utilization of the Rabbi Trust shall be borne solely by LFC Creditor
         Trust.

         (b)     All payments to be made by the Trustee to the LFC
Administrative Beneficiary or Reorganized LMUSA shall be made only from the
assets, income and proceeds of the Trust and only to the extent that the
Trustee shall have received sufficient assets, income or proceeds of the Trust
Assets to make such payments in accordance with the terms of this SECTION 4.3.
The LFC Administrative Beneficiary and Reorganized LMUSA shall look solely to
the assets, income and proceeds of the Trust for any distributions as herein
provided.

         (c)     As often as, in the discretion and judgment of the Trustee,
there shall be an amount of monies in the Trust sufficient to render feasible a
distribution of cash or other property to the LFC Administrative Beneficiary
and Reorganized LMUSA, but (subject to there being a sufficient amount
available pursuant to the terms of this subsection) no less often than
annually, the Trustee shall distribute and pay, or cause to be distributed and
paid, to the LFC Administrative Beneficiary and Reorganized LMUSA, such
aggregate amount of cash or other non-cash property designated by the Trustee
in his discretion for distribution to the LFC Administrative Beneficiary and
Reorganized LMUSA, if any, as shall then be held in the Trust, excluding
reasonable amounts of cash held in the reserve funds pursuant to SECTION 4.1 OR
4.2 or held for withholding of taxes or other charges pursuant to SECTION 4.7
or otherwise needed to pay the expenses, debts, charges, liabilities and
obligations of the Trust. The distributions shall be in accordance with
Paragraph 13(i) of the Intercreditor Agreement. In accordance with Revenue
Procedure 94-45, 1994-28 I.R.B.124, the Trustee is required to distribute all
current income (including the proceeds of any asset sale) to the beneficiaries
at least annually, except that the Trustee may retain an amount of net proceeds
or net





                                      -9-

                                      LFC/LMUSA JOINT LITIGATION TRUST AGREEMENT
<PAGE>   14
income reasonably necessary to maintain the value of its assets or to meet
claims and contingent liabilities (including disputed claims).

         4.4     Final Distribution. If the Trustee determines that all claims,
debts, liabilities and obligations of the Trust, whether contingent or
noncontingent, disputed or undisputed, liquidated or unliquidated have been
paid or discharged, and that all the Trust Assets have been converted to cash
or non-cash property designated by the Trustee in his discretion for
distribution to the LFC Administrative Beneficiary and Reorganized LMUSA, or if
the existence of the Trust shall terminate pursuant to SECTION 3.1 OR 3.2, the
Trustee shall, as expeditiously as is consistent with the conservation and
protection of the Trust, and notwithstanding the distribution provisions of
SECTION 4.3, distribute the Trust Assets to the LFC Administrative Beneficiary
and Reorganized LMUSA subject to maintaining a reserve for expenses incurred in
winding up the Trust pursuant to SECTIONS 4.1 AND 4.2. The distributions shall
be in accordance with Paragraph 13(i) of the Intercreditor Agreement.

         4.5     Reports to LFC Administrative Beneficiary and Reorganized
LMUSA. As soon as practicable but not later than 120 days after the end of each
fiscal year of the Trust and after termination of the Trust, the Trustee shall
submit a written report and account to the LFC Administrative Beneficiary,
Reorganized LMUSA and the Beneficiaries' Committee showing (a) the assets and
liabilities of the Trust at the end of each fiscal quarter or upon termination
of the Trust and the receipts and disbursements of the Trustee for such fiscal
year or period, certified by independent public accountants, (b) any changes in
the Trust Assets which have not previously been reported, (c) any action taken
by the Trustee in the performance of his duties under this Agreement which he
has not previously reported and which in his opinion materially affects the
Trust and (d) if applicable, the amount of compensation paid to the Trustee for
the prior year pursuant to SECTION 7.1. The Trustee may submit similar reports
for such interim periods during the fiscal year as he in his discretion deems
advisable. In addition, the Trustee shall provide a report describing the
occurrence of any material events concerning the Trust, the Trustee or the
Trust Assets. The fiscal year of the Trust shall end on the last day of
December of each year unless the Trustee deems it advisable to establish some
other date as the date on which the fiscal year of the Trust shall end;
provided that establishment of such other date is permissible under the Tax
Code.

         4.6     Income Tax Information. (a) The Trustee shall, at the time and
in the manner prescribed by the Tax Code and Revenue Procedure 94/45, 1994-28
I.R.B.124, file such tax returns and reports as may be required by applicable
law and specifically must file the tax returns of this Trust as a grantor-trust
according to Treasury Regulation 1.671-4(a), and shall promptly furnish copies
of such returns and reports as filed to the Administrative Beneficiary,
Reorganized LMUSA and the Beneficiaries' Committee.

         (b)     As soon as practicable after the close of each fiscal year,
the Trustee shall mail to the LFC Administrative Beneficiary, Reorganized LMUSA
and the Beneficiaries' Committee a statement showing the dates and amounts of
all distributions made by the Trustee and such other information as is
reasonably available to the Trustee which may be helpful to the LFC

Administrative Beneficiary and Reorganized LMUSA for the proper reporting of
income with respect to assets held by it as trustee for the benefit of certain
creditors pursuant to the Plan.

         The Trustee may retain professionals to perform his duties under this
SECTION 4.6, and may rely upon the performance of such professionals with
respect to such duties.

         4.7     Withholding of Taxes and Other Charges. The Trustee may
withhold from any amounts distributable at any time to the LFC Administrative
Beneficiary and Reorganized LMUSA such sum or sums as may be sufficient to pay
any tax or taxes or other charge or charges which have been or may be imposed
on the LFC Administrative Beneficiary and Reorganized LMUSA under the income
tax laws of the United States or of any state or political subdivision or
entity by reason of any distribution provided for in SECTIONS 4.3 and 4.4,
whenever such withholding is required by any law, regulation, rule, ruling,
directive or other governmental requirement, and the Trustee, in the exercise
of his discretion and judgment, may enter into agreements with taxing or other
authorities for the payment of such amounts as may be withheld in accordance
with the provisions of this SECTION 4.7. Notwithstanding the foregoing but
without prejudice to the Trustee's rights hereunder, the LFC Administrative
Beneficiary and Reorganized LMUSA shall have the right with respect to the
United States or any state or political subdivision or entity to contest the
imposition of any tax or other charge by reason of any distribution hereunder.

         4.8     Other Reports. The Trustee shall prepare and file audited
year-end and unaudited interim financial reports as may be required by
regulatory authorities (if any), applicable laws, rules or regulations or as
the Trustee in his discretion deems advisable during the fiscal year.

                                   ARTICLE 5

time, on behalf of the Trust or the LFC Administrative Beneficiary and
Reorganized LMUSA, enter into or engage in any business or any development of
real property, and no part of the Trust Assets or the proceeds, revenue or
income therefrom shall be used or disposed of by the Trustee in furtherance of
any business or development of real property. This limitation shall apply

short-term certificates of deposit of federally insured banking institutions
having in excess of $500,000,000 in capital and surplus that will ensure that
this Trust remains a pass-through grantor trust under Revenue Procedure 94-45,

or otherwise liquidate the investment until such time as such funds are (a)
needed to pay expenses incurred pursuant to this Agreement, or (b) to be
distributed pursuant to SECTIONS 4.3 AND 4.4; provided, however, that the
Trustee may liquidate such





                                      -11-

investments if the Trustee determines in his discretion that liquidation is
necessary to protect the Trust from loss on the amounts invested. The Trustee

the Trustee's status as Trustee.

the provisions of SECTION 5.1, The Trustee shall have the following specific
powers and responsibilities in addition to any powers and responsibilities
conferred upon him by any other section or provision of this Agreement:

of the Trust Assets is situated in any state or other jurisdiction in which the
Trustee is not qualified to act as Trustee, to nominate and appoint an
individual or corporate trustee qualified to act in such state or other
jurisdiction in connection with the property situated in the state or other
jurisdiction as a trustee of such property and require from such trustee such
security as may be designated by the Trustee. The trustee so appointed shall
have all the rights, powers, privileges and duties of the Trustee hereunder and
shall be subject to the conditions and limitations of this Trust, except as
modified or limited by the Trustee herein and except where the same may be
modified by the laws of such state or other jurisdiction (in which case, the
laws of the state or other jurisdiction in which such trustee is acting shall
prevail to the extent necessary). Such trustee shall be answerable to the
Trustee herein appointed for all monies, assets and other property which may be
received by it in connection with the administration of such property, and
shall be compensated as the Trustee shall determine. The Trustee hereunder may
remove such trustee, with or without cause, and appoint a successor trustee at
any time by the execution by the Trustee of a written instrument declaring such
trustee removed from office and specifying the effective date and time of
removal;

         (i)     To perform any act authorized, permitted or required under any
instrument, contract, agreement or cause of action relating to or forming a
part of the Trust, whether in the nature of an approval, consent, demand or
notice thereunder or otherwise, unless such act would require the consent of
the LFC Administrative Beneficiary or Reorganized LMUSA in accordance with the
express provisions of this Agreement;

         (j)     To file or cause to be filed all required federal, state,
local and foreign tax filings, make any tax elections available to the Trust
under federal, state, local or foreign law, and prepare applications for
rulings or other administrative determinations from federal, state, local and
foreign tax authorities as may be reasonably necessary to determine the tax
liabilities of the Trust or its Beneficiaries;

         (k)     In connection with his duties hereunder, to employ such
agents, nunc pro tunc to October 31, 1996, including counsel, accountants,
experts, advisors or other persons (which counsel, accountants, experts,
advisors or other persons may serve in the future, serve at present, or have
served in the past in such capacity or a similar capacity for the Beneficiaries
or the LFC or LMUSA Creditors' Committees), and to confer upon them such
authority as the Trustee in his discretion may

deem appropriate, and to pay reasonable compensation therefor upon submission
of invoices; provided, however, that the Trustee may not retain as counsel of
record in any litigation he may commence the law firm of which the Trustee is a
member, partner, or otherwise associated; further provided, however, that the
Trustee may retain such firm of which he is a member, partner or otherwise
associated to perform such other legal services concerning the administration
of the trust and advice concerning the investigation and coordination of the
various potential claims and litigations, as the Trustee may in his discretion
deem appropriate; and

         (l)     To waive any attorney-client privilege that existed or exists
as between the Debtors and their counsel respecting claims held by the Trust so
as to cause such counsel to disclose all information to the Trustee.

         5.3     Discretionary Submission of Questions to LFC Administrative
Beneficiary and/or Reorganized LMUSA on Behalf of Creditors Trust. The Trustee,
in his sole discretion and judgment, may, but shall not be required to, submit
to the Beneficiaries' Committee at any time, and from time to time, any question
or questions regarding which the Trustee may desire to have explicit approval
of the Beneficiaries' Committee for the taking of any specific action proposed
to be taken by the Trustee with respect to the Trust, or the administration and
distribution of the Trust Assets. Any Trustee shall be protected in acting in
good faith in reliance upon such instructions and shall have no liability for
acting in accordance therewith. If the Trustee, in his sole discretion and
judgment, determines that the investigation or prosecution of any particular
claim or cause of action might involve him or the law firm of which he is a
member, partner or otherwise associated to have a conflict of interest or a
violation of the Code of Professional Responsibility, the Trustee may recuse
himself from further involvement in such claim or cause of action other than to
submit to the Beneficiaries' Committee any relevant information in his
possession. It shall then be the responsibility of the Beneficiaries' Committee
to appoint one or more substitute trustees ("Substitute Trustee") under SECTION
5.2(A) to take such actions as they may deem appropriate with respect to such
claim or cause of action, including retention of professionals and any other
duties that would otherwise be exercised by the Trustee hereunder; provided,
however, that the Trustee shall have the right to recommend a Substitute
Trustee to the Beneficiaries' Committee. The compensation for any such
Substitute Trustee(s) shall be equivalent to the percentage of net proceeds
distributed to creditors that would otherwise be paid to the Trustee under
SECTION 7.1 for such recovery. The Substitute Trustee shall be required to
execute an agreement with the Trustee evidencing his appointment hereunder and
agreeing to be bound hereby. In the event that the Beneficiaries' Committee
fails to respond or direct a Trustee within the time reasonably designated by
the Trustee, the Trustee may take such action as it deems appropriate or may
take no action, in either case without liability for such action or failure to
act. All costs and expenses incurred by the Trustee in the exercise of any
right, power or authority conferred by this SECTION 5.3 shall be costs and
expenses of the Trust. With respect to any Substitute Trustee, the Trustee
shall have the right to approve a budget for such Substitute Trustee.

         5.4     Additional Powers of Trustee. Subject to the express
limitations contained herein, the Trustee shall have, and may exercise with
respect to the Trust Assets, or any part thereof, and to the administration and
distribution of the Trust Assets, all powers now or hereafter conferred on





                                      -14-

                                      LFC/LMUSA JOINT LITIGATION TRUST AGREEMENT

trustees by the laws of the State of Delaware. The powers conferred by this
SECTION 5.4 in no way limit any power conferred on the Trustee by any other
section hereof but shall be in addition thereto; provided, however, that the
powers conferred by this SECTION 5.4 are conferred and may be exercised only
and solely within the limitations and for the limited purposes imposed and
expressed in ARTICLE 2 and in SECTION 5.1. Moreover, the powers of the Trustee
are hereby expressly limited to those necessary to maintain the value of and
liquidate the Trust assets.

         5.5     Limitations on Powers of Trustee to Deal with Trust in
Non-Fiduciary Capacity. The Trustee may not sell property to or borrow property
from the Trust. The Trustee may not acquire property from the Trust unless such
acquisition is approved in advance by (a) the Bankruptcy Court or (b) the
Securities and Exchange Commission pursuant to Section 17(b) of the Investment
Company Act.

                                   ARTICLE 6

                             CONCERNING THE TRUSTEE

         6.1     Generally. The Trustee accepts and undertakes to discharge the
Trust upon the terms and conditions hereof. The Trustee shall exercise those
rights and powers vested by this Agreement, and use the same degree of care and
skill in his exercise as a prudent person would exercise or use under the
circumstances in the conduct of his own affairs. Notwithstanding anything to
the contrary stated or implied in this Agreement, the Trustee shall not be
liable under this Agreement other than for his proven willful misconduct.

         6.2     Transferee Liabilities. If any liability shall be asserted
against the Trust or the Trustee as the transferee of the Trust Assets, on
account of any claimed liability of or through the Debtors or the LFC
Administrative Beneficiary or Reorganized LMUSA, the Trustee may use such part
of the Trust Assets as may be necessary in contesting any such claimed
liability and in payment, compromise, settlement and discharge thereof on terms
reasonably satisfactory to the Trustee in his discretion. In no event shall the
Trustee be required to use his personal funds or assets for such purposes. In
the event that the Trust does not have sufficient Trust Assets available for
such purpose at the time such liability is asserted, the Trustee shall be
entitled (but not required) to take appropriate action and advance any costs or
expense, subject to reimbursement from Trust Assets when available.

         6.3     Reliance by Trustee. Except as otherwise provided in SECTION
6.1:

         (a) The Trustee may rely and shall be protected in acting upon any
resolution, certificate, statement, instrument, opinion, report, notice,
request, consent, order or other paper or document believed by him to be
genuine and to have been signed or presented by the proper party or parties.





                                      -15-

<PAGE>   20
         (b)     The Trustee may consult with legal counsel or other
professionals to be selected by him, and the Trustee shall not be liable for
any action taken or suffered by him in accordance with the advice of such
professionals.

         6.4     Indemnification of Trustee. The Trustee shall be indemnified
by and receive reimbursement from the Trust against and from any and all loss,
liability or damage, including payment of attorneys' fees and other costs of
defending himself, which he may incur or sustain, other than as a result of
proven willful misconduct, in the exercise and performance of any of the powers
and duties hereunder. The Trustee may purchase with assets of the Trust, such
insurance as he feels, in the exercise of his discretion, adequately insures
that he shall be indemnified against any such loss, liability or damage
pursuant to this SECTION 6.4. Expenses (including attorneys' fees) and other
costs of the Trustee's defense shall be paid by the Trust in advance of the
final disposition of any claims against the Trustee upon receipt of an
undertaking by or on behalf of the Trustee to repay such amounts if it shall be
ultimately determined that he is not entitled to be indemnified by the Trust as
authorized in this SECTION 6.4. The terms of this SECTION 6.4 shall continue to
apply to any former Trustee.

         6.5     No Implied Duties. The Trustee shall not manage, control, use,
sell, dispose, collect or otherwise deal with the Trust or otherwise take any
action hereunder except as expressly provided herein, and no implied duties or
obligations shall be read into this Trust Agreement against the Trustee. The
Trustee nevertheless agrees that he will promptly take such action as may be
necessary to duly discharge any liens or encumbrances on any part of the Trust
Assets which result from claims against the Trustee not related to (a) the
ownership or administration of the Trust Asset, (b) any other transaction
pursuant to this Trust Agreement or (c) any document included in the Trust
Assets.

         6.6     Trustee's Lien. The Trustee shall have a lien on the Trust
Assets and the proceeds thereof for the amount of any unpaid fees and expenses,
and any liability, loss or expense that may be incurred by him in connection 
with the performance of his duties hereunder, including the expense of
defending any action or proceeding instituted against him, with respect to
which he is entitled to indemnification pursuant to SECTION 6.4.

         6.7 No Personal Liability. Persons dealing with the Trust must look
solely to the Trust or trust property for the enforcement of any claims
against the Trust or to satisfy any liability incurred by the Trustee to such
persons in carrying out the terms of this Trust, and neither the Trustee nor
the LFC Administrative Beneficiary, Reorganized LMUSA nor the Beneficiaries'
Committee shall have any personal liability or individual obligation to satisfy
any such liability.

         6.8     Valuation of Trust Assets. As soon as possible after the date
of this Agreement but in no event later than ninety (90) days thereafter, the
Trustee shall obtain a complete valuation of the Trust Assets transferred to
the Trust, and such valuation shall be used consistently by the Trustee, the
Debtor and the Beneficiaries for all federal income tax purposes. Thereafter,
the Trustee must obtain consistent valuations of the assets, pursuant to
Revenue Procedure 94-45, 1994-28 I.R.B.124.

                                   ARTICLE 7

                            COMPENSATION OF TRUSTEE

         7.1     Amount of Compensation. The Trustee shall receive as
compensation for services as Trustee hereunder, paid from the Trust Assets, an
amount equal to 2.5% of the aggregate distribution to creditors during the
entire term of this Agreement up to $30 million in recoveries and 3% on the
aggregate distribution to creditors in excess of $30 million (the "Trustee's
Commissions"). The aggregate recoveries shall be determined on a cumulative
basis. The Trustee shall have a right to draw from the Trust Assets as an
advance against the Trustee's Commissions a salary in the amount of $10,000
per month for the first year after the date of this agreement and $7,000 per
month for the second year. Such advances should be credited against any
Trustee's Commissions, but in the event that the Trustee's Commissions are less
than the amount of advances he has received, the Trustee shall not be required
to reimburse the Trust for any such amounts. The amount of such compensation
shall be included in the annual report to be sent the Beneficiaries' Committee,
LFC Administrative Beneficiary and Reorganized LMUSA pursuant to SECTION 4.5.

         7.2     Dates of Payment. The advances payable to the Trustee pursuant
to the provisions of SECTION 7.1 shall be paid monthly in arrears, commencing
with the month of January, 1997.

                                   ARTICLE 8

                         TRUSTEE AND SUCCESSOR TRUSTEES

         8.1     Number of Trustees. Subject to the provisions of SECTION 8.3
relating to the period pending the appointment of a successor Trustee, there
shall always be one and only one Trustee of this Trust. If any corporate
Trustee shall ever change its name, or shall reorganize or reincorporate, or
shall merge with or into or consolidate with any other bank or trust company,
such corporate Trustee shall be deemed to be a continuing entity and shall
continue to act as a Trustee hereunder with the same liabilities, duties,
powers, titles, discretion and privileges as are herein specified for a
Trustee.

         8.2     Resignation and Removal. The Trustee may resign and be
discharged from the Trust hereby created by giving written notice thereof to
the LFC Administrative Beneficiary, Reorganized LMUSA and the Beneficiaries'
Committee as their addresses appear in the records of the Trust. Such
resignation shall become effective on the day specified in such notice or upon
the appointment of such Trustee's successor and such successor's acceptance of
such appointment, whichever is earlier. Any Trustee may be removed by agreement
of the Beneficiaries' Committee at any time with cause, or at any time after
the end of the third full fiscal year following the date of this Agreement,
without cause. The Trustee shall be entitled to compensation in accordance with
SECTION 7.1 in respect of amounts received by Trustee on all claims for which
actions or proceedings have been instituted prior to Trustee's termination.

<PAGE>   22
         8.3     Appointment of Successor Trustee. Should the Trustee at any
time resign or be removed, or die or become incapable of action, or be adjudged
a bankrupt or insolvent, a vacancy shall be deemed to exist and a successor
Trustee shall be appointed as soon as possible by the Beneficiaries' Committee
(with each having equal say); provided that such appointment shall be subject
to the approval of the Bankruptcy Court; provided, further, that no
stockholder, officer or director of the Beneficiaries' Committee shall be
appointed as a successor Trustee; and provided, further, that the Trust shall
have the right to nominate the successor Trustee. In the event that an election
has been made to treat the Trust as a Delaware business trust, if the Trust
ceases to have at least one Trustee who, in the case of a natural person, is a
Delaware resident or, in all other cases, has its principal place of business
in Delaware, appropriate action shall be taken to file a certificate of
cancellation.

         8.4     Acceptance of Appointment by Successor Trustee. Any successor
Trustee appointed hereunder shall execute an instrument accepting such
appointment hereunder and shall deliver one counterpart thereof, to the
retiring Trustee (in the case of a resignation). Thereupon such successor
Trustee shall, without any further act, become vested with all the estates,
properties, rights, powers, trusts and duties of his predecessor in the Trust
with like effect as if originally named herein; but any retiring Trustee shall
nevertheless, when requested in writing by the successor Trustee, execute and
deliver an instrument or instruments conveying and transferring to such
successor Trustee upon the trust herein expressed, all the estates, properties,
rights, powers and trusts of such retiring Trustee, and shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
him hereunder.

         8.5     Bonds. Unless a bond is required by law, no bond shall be
required of the original or any successor Trustee hereunder. If a bond is
required by law, no surety or security with respect to such bond shall be
required unless required by law.

                                   ARTICLE 9

           POWERS AND RESPONSIBILITIES OF THE BENEFICIARIES' COMMITTEE

         9.1     Any action to be taken or any question arising for a decision

the members then in office or by a writing signed by all members. The
Beneficiaries' Committee may provide for the authentication of evidence of any
action taken by them. Any member may vote in person or by proxy given to any
other member.

however, that no person serving as a member of the Beneficiaries' Committee
shall be an Affiliated Person of Reorganized LFC; Reorganized LIS; Reorganized
LAS or Reorganized LMUSA. Each member of the Beneficiaries' Committee shall
have an equal vote with respect to





                                      -18-

                                      LFC/LMUSA JOINT LITIGATION TRUST AGREEMENT

shall consist of [Robert Masterson) and [Paul Leff]. Each member of the
Beneficiaries' Committee may appoint one or more persons to act as their agent
in order to carry out their obligations under this Agreement; provided however,
that such person shall not be an Affiliated Person. The Beneficiaries'
Committee hereby appoints Weil, Gotshal & Manges and Andrews & Kurth L.L.P. as
their agent and attorneys in fact with respect to the appointment of a trustee
pursuant to SECTIONS 5.3 AND 8.3.

         9.3     The members of the Beneficiaries' Committee are expressly
authorized to incur and pay those reasonable charges and expenses that they may
deem necessary and proper for administering this Agreement. The Trustee agrees
to reimburse and indemnify the members of the Beneficiaries' Committee to the
extent of the Trust Assets for all claims, expenses, and liabilities incurred
by them in connection with the discharge of their duties under this Agreement.

         9.4     No member of the Beneficiaries' Committee shall be liable for
acts or defaults of any other member or for acts or defaults of any agent of
any other member. The member shall be free from liability in acting upon any
paper, document, or signature believed by them to be genuine and to have been
signed by the proper party. The members of the Beneficiaries' Committee shall
not be liable for any error or judgment nor any act done or omitted, nor for
any mistake of fact or law, faith, nor generally shall the member have any
accountability pursuant to this Agreement, except that each member shall be
liable for his or her own willful default or gross negligence. The members may
be advised by legal counsel, and any action under this Agreement taken or
suffered in good faith by them in accordance with opinion of counsel shall be
conclusive on the parties to this Agreement, and the members shall be fully
protected and be subject to no liability in respect to any action taken or
suffered under this Agreement.

         9.5     The Beneficiaries' Committee may adopt Bylaws and any other
form of rules to govern the internal affairs of the Beneficiaries' Committee.

         9.6     Any member of the Beneficiaries' Committee may at any time
resign by giving to the Beneficiaries' Committee a written resignation to take
effect thirty (30) days thereafter or upon the prior acceptance thereof. In the
event of the death, disability or resignation of a Committee member, a
successor member shall be appointed by the resigning member of the Committee.

                                   ARTICLE 10

                                   AMENDMENTS

         10.1    Amendments. The LFC Administrative Beneficiary and Reorganized

investments of funds included in the Trust Assets except as permitted in
SECTIONS 5.1 and 5.2. After consultation with the Trust Committees, the Trustee
may propose to the Court a modification, supplementation or amendment of this
Agreement. Such modification,
