I                                : SALE AND PURCHASE
                                 -------------------

 .0  SALE AND PURCHASE OF PARTNERSHIP INTERESTS AND MEMBERSHIP INTERESTS.
Pursuant to the terms and provisions of this Agreement and subject to the
conditions hereinafter set forth, on the Closing Date, Buyer will purchase from
the Sellers all of their Partnership Interests and the Membership Interests of
MCIC Corp in MCLtd.  Such purchased securities shall be transferred and assigned
to Sub I and Sub II as directed by Alliance in its sole discretion.

 .1  PURCHASE PRICE.  The aggregate purchase price, subject to the adjustments
as provided in this Agreement, shall be Thirteen Million Dollars ($13,000,000)
(subject to such adjustments, the "Purchase Price") payable in cash as follows:
(a) on the Closing Date, Buyer will wire transfer to accounts designated by
Sellers, in immediately available federal funds, an amount equal to Eleven
Million Dollars ($11,000,000) (subject to the adjustments to the Purchase Price
set forth herein) and (b) on the Closing Date, Buyer will wire transfer to an
account designated by the Escrow Agent (as defined in the Escrow Agreement), in
immediately available federal funds, Two Million Dollars ($2,000,000) (including
any interest accrued thereon, the "Escrow Amount") to the Escrow Agent in
accordance with the terms of an escrow agreement (the "Escrow Agreement") in the
form attached hereto as EXHIBIT "B".  The Escrow Amount shall be held by the
Escrow Agent for Buyer's use as security for the obligations of the Sellers
referred to in this Agreement (including, without limitation, the indemnity
obligations of the Sellers referred to in Article IX herein).  In the event
that, as of the date on which the remaining Escrow Amount would otherwise be
released to the Sellers, there remain one or more outstanding Claims for which
the Sellers may be required to make payment as provided in this Agreement, then
the Escrow Agent shall continue to hold a portion of the Escrow Amount, in
accordance with the terms of the

                                          4
<PAGE>

Escrow Agreement, until the final resolution of such Claim or Claims.  The
Sellers' agreed upon allocation of the Purchase Price among the Sellers shall be
equal to the percentages shown on EXHIBIT "A" attached hereto,  which Buyer
shall utilize both for the payment of the Purchase Price on the Closing Date and
the Escrow Agent shall utilize for the release of any amount of the Escrow
Amount to the Sellers, as applicable.  Each of the Sellers acknowledges that it
has agreed to such allocation and that Buyer and Escrow Agent shall have no
responsibility for such allocation, and each Seller agrees to indemnify and hold
Buyer and Escrow Agent harmless from and against any disputes, disagreements or
claims (including, without limitation, all costs and expenses incurred in
connection therewith) arising from or challenging such allocation.  The Purchase
Price shall be reduced by (a) subject to the last sentence of this Section, the
amount of the bonuses to be paid by any of the Operating Entities to certain of
the officers, agents, directors and employees thereof, whether such bonuses are
to be paid as of the Closing Date or have been committed by any of the Operating
Entities to be paid at a subsequent date, all of which bonuses are listed on
SCHEDULE 2.2(b) hereof, (b) amounts required to retire all outstanding options,
each as listed on SCHEDULE 2.2(b) and (c) the aggregate amount of fees and
expenses paid, payable or incurred by any of the Operating Entities in
connection with this Agreement and the transactions contemplated hereby (the
"Transaction Expenses"), as estimated on SCHEDULE 2.2(c).  Final expenses will
be provided on an updated SCHEDULE 2.2(c) on the date immediately preceding the
Closing Date.  Upon the execution of this Agreement and unless terminated in
accordance with the terms hereof, if the Closing fails to occur prior to
November 19, 1997, the Purchase Price shall increase by Five Thousand Dollars
($5,000) per day (the "Delinquency Amount"), beginning November 19, 1997, until
the Closing Date; provided, however, that (i) such November 19 date shall be
conterminously extended to the extent that Buyer makes the filing required under
the HSR Act and Sellers or Shareholders, as applicable, do not, within five (5)
days following the date of this Agreement, and (ii) the Purchase Price shall not
be increased by the Delinquency Amount, if the failure of the Closing to occur
by that date is due to Sellers' inability to satisfy the closing condition
expressed in any of paragraphs (a), (c), (e), (f), (h), (i), (j), (k), (n), (p),
(q), or (r), of Section 8.1.  For the avoidance of doubt, a delay in the Closing
caused by the necessity of obtaining any third party lessor or customer consent
shall not result in an extension of the November 19 date for purposes of
computation of the Delinquency Amount.  Notwithstanding the foregoing, with
respect to year-end discretionary bonuses payable to employees of the Operating
Entities, Sellers shall be responsible for one-third of the amount thereof, such
one-third amount shall not exceed Fifty Thousand Dollars ($50,000); Buyer will
invoice the Sellers at the time that final year-end discretionary bonuses are
determined, and Sellers will be required to make cash payment to Buyer within
ten (10) days of receipt of such invoice.  The year-end discretionary bonuses
shall be reasonably consistent with the amount provided in the prior year and
Buyer shall consult with Sellers regarding the amount of such final year-end
discretionary bonuses.

 .2  ASSET VALUATION.  The assets of the Operating Entities shall be valued as
set forth on SCHEDULE 2.3 (the "Asset Valuation").  Each Seller and the Buyer
covenants and agrees

                                          5
<PAGE>

that it shall utilize such Asset Valuation when filing all applicable forms with
the Internal Revenue Service and any other Tax authority and further covenants
and agrees that it will not take a position on any federal, state or local tax
return, before any governmental agency charged with the collection of any tax or
in any judicial proceeding that is in any way inconsistent with the Asset
Valuation and will cooperate with one another in the timely filing (consistent
with such Asset Valuation) on the applicable tax forms with the Internal Revenue
Service or any other governmental agency of all applicable tax returns.

 .3  CERTAIN CONTRACT RIGHTS.  Without limiting the generality of actions to be
taken and documents to be delivered by or on behalf of Sellers at the Closing,
Sellers agree to (i) cause an assignment of all (A) agreements and arrangements
with customers of the Operating Entities and (B) other Material Contracts of the
Operating Entities designated by Buyer prior to the Closing, in each case from
the existing Operating Entity party thereto to MCLtd, and (ii) provide
reasonably satisfactory evidence of such assignment(s) to Buyer.

 .4  ADMISSION AS NEW PARTNERS OR MEMBERS.  In accordance with Article V of the
First Amended and Restated Partnership Agreement of MCIC (the "Partnership
Agreement") and Article V of the Operating Agreement of MCLtd (the "Operating
Agreement"), each of the Sellers agrees to the sale and transfer of the
Partnership Interests and Membership Interests to Buyer and to the admission of
any of Alliance, Sub I or Sub II as new partners or members of MCIC and MCLtd,
respective, and that such sale, transfer or admission shall not trigger any
dissolution or termination provision of MCIC or MCLtd under Article VII of the
Partnership Agreement or Article VII of the Operating Agreement.  In accordance
with the terms of the Partnership Agreement and Operating Agreement, each of the
Sellers acknowledges receipt of written notice of the proposed transfer or sale
of the Partnership Interests and Membership Interests, waives any and all rights
of first refusal and waives any and all time and notice requirements contained
therein.


II                            : CLOSING AND CLOSING DATE
                              --------------------------

Interests and Membership Interests and the other transactions provided for in
this Agreement (the "Closing") shall take place at the offices of Kahn,
Kleinman, Yanowitz & Arnson Co., L.P.A., on the earliest practicable date
following the satisfaction (or waiver by the appropriate party(ies)) of the
conditions precedent to Closing set forth in Article VIII herein, commencing at
10:00 a.m. local time, and all other transactions provided for herein to occur
on and as of the Closing Date shall be deemed to have occurred simultaneously
and to be effective as of the close of business on such date.

 .1  DELIVERY AT CLOSING.  Concurrently with the Closing, Buyer will deliver (or
cause to be delivered) to the Sellers, and Sellers will deliver (or cause to be
delivered) to Buyer those consents, agreements, certificates, documents and
instruments described in a closing agenda to be delivered prior to the Closing.

attached hereto.

 .4  FINANCIAL STATEMENTS; NO UNDISCLOSED LIABILITIES.  (a) The Sellers have
delivered to Buyer true and complete copies of (i) the audited consolidated
balance sheets of MCIC at December 31, 1994, 1995 and 1996, and the related
consolidated statements of income, cash flow and changes in partners' equity for
the fiscal years then ended, and (ii) the audited balance sheets of MCIC-HNI and
Leasing at December 31, 1994, 1995 and 1996, and the related statements of
income, cash flow and changes in partners' equity for the fiscal years then
ended (collectively, the materials referred to in clauses (i) and (ii) are the
"Financial Statements") all of which have been prepared in accordance with
generally accepted accounting principles consistently applied ("GAAP")
throughout the periods involved, other than accruals for any employee vacation
pay obligations.  Such balance sheets, including the related notes thereto, as
of their respective dates, fairly present the financial position, assets and
liabilities (whether accrued, absolute, contingent or otherwise) of MCIC,
MCIC-HNI and Leasing, respectively, and such statements of income, cash flow and
changes in partners' equity fairly present the results of operations, cash flow
and changes in partners' equity of MCIC, MCIC-HNI and Leasing, respectively, for
the periods indicated, all in accordance with GAAP.  The Sellers have delivered
to Buyer true and complete copies of (x) the unaudited consolidated financial
statements of MCIC as of and for the period ended August 31, 1997, and (y) the
unaudited financial statements of MCIC-HNI and Leasing as of and for the period
ended August 31, 1997 (collectively, the materials referred to in clauses (x)
and (y) are the "Interim Statements").  Except as noted therein and subject to
normal year end adjustments which are not expected in the aggregate to be
material and accruals for bonuses payable to officers, agents, directors and
employees, the Interim Statements fairly present the financial position, assets
and liabilities (whether accrued, absolute, contingent or otherwise) of such
entities at August 31, 1997 and the results of such entities' respective results
of operations, cash flow and changes in partners' equity for the eight months
then ended, all in conformity with GAAP and applied on a consistent basis with
prior periods; provided, however, footnotes required by GAAP have been omitted
from such Interim Statements.  Sellers represent that for both financial
statement and tax purposes, the assets, liabilities and operations of each of
MCLtd, SPECT and MCIC-MMMC have been consolidated with those of MCIC.

    (b)  Except as set forth in SCHEDULE 4.5 attached hereto or set forth in
the Financial Statements and the Interim Statements, there is no claim,
liability or obligation of any nature, whether absolute, accrued, known or
unknown, contingent or otherwise, affecting the Operating Entities or their
businesses, other than obligations incurred in the ordinary course of such
businesses consistent with past practice, none of which constitutes a Material
Adverse Effect.

    (c)  SCHEDULE 4.5 attached hereto lists each distribution, dividend or
similar payment to the Sellers on or with respect to the Partnership Interests
and/or Membership Interests made during 1997 and through the Closing Date.

 .5  ACCOUNTS RECEIVABLE.  Except as set forth in SCHEDULE 4.6 attached hereto,
the accounts receivable of each of the Operating Entities arising from their
respective operations as reflected in the Financial Statements, the Interim
Statements and the latest available monthly balance sheets delivered to the
Buyer by the Sellers represent valid claims against the account debtors for
sales made or services rendered by the Operating Entities in the ordinary course
of business consistent with past practice.

 .6  INTELLECTUAL PROPERTY.  Set forth on SCHEDULE 4.7 attached hereto is a list
of all trade names, assumed names, service names, service marks, trademarks,
logos, patents, copyrights, licenses and other tangible or written intellectual
property rights (the "Intellectual Property") owned by the Operating Entities or
used or required by the Operating Entities in the operation of their businesses.
Except as set forth on SCHEDULE 4.7 attached hereto, the Operating Entities hold
all the right, title and interest in and to the Intellectual Property, free and
clear of all Liens.  The Operating Entities own or have the right to use,
without the making of any payment (other than (i) a payment made in connection
with an equipment lease listed on SCHEDULE 1.8 or (ii) periodic payments to and
filings with a governmental authority for continued usage or validity) or the
granting of any rights to others, all Intellectual Property necessary to conduct
its business as presently being conducted.  Except as set forth on SCHEDULE 4.7
attached hereto, to the Knowledge of Sellers, the conduct of the business of the
Operating Entities as now conducted does not infringe or conflict with any
intellectual property rights of others.  The Operating Entities have, as of the
date hereof, and will have as of the Closing Date, satisfied all governmental
requirements necessary to maintain the validity of all Intellectual Property,
and the right to use such Intellectual Property; provided, that this sentence
shall apply only to such of the Intellectual Property as is subject to or
covered by applicable statutes or regulations affecting the validity and/or
right to use intellectual property rights.  Except as set forth on SCHEDULE 4.7
attached hereto, no suit or proceeding by others alleging infringement of any
intellectual property rights of such third parties is pending against any
Operating Entity, or to the Knowledge of Sellers, threatened against any
Operating Entity by any third party.  All licenses, rights and other agreements
pertaining to the Intellectual Property are in compliance in all material
respects with all applicable laws, rules and regulations in all jurisdictions in
which the Operating Entities conduct any business.  Except as set forth on
SCHEDULE 4.7, the execution and delivery of this Agreement and the consummation
of the transactions contemplated hereby will not alter or impair the rights and
interests of the Operating Entities in any of the Intellectual Property and the
Operating Entities will have the same rights and interests in such items at and
after the Closing Date as they had immediately prior to the Closing Date.

promissory notes and other documents evidencing or relating to debt for borrowed

is there any basis for any claim of breach or default, in any obligation to be

SCHEDULE 4.9.  SCHEDULE 4.9 discloses for each policy the risks insured against,
coverage limits, deductible amounts, all outstanding claims thereunder, the
carrier, and whether the terms of such policy provide for retrospective premium
adjustments.  All such policies are in full force and effect in accordance with
their terms, no notice of cancellation has been received, and to the Knowledge
of Sellers, there is no existing breach or default or event which, with the
giving of notice or lapse of time or both, would constitute a breach or default

the Knowledge of Sellers, there are no organizational efforts presently being
made involving any of such employees.  Each Operating Entity's relations with
its employees are generally good.  Except as disclosed on SCHEDULE 4.10, the
Sellers have no actual knowledge that any executive or officer of an Operating
Entity has any plans to terminate his or her employment with such Operating
Entity.

    (b)  ERISA.

         (b)  SCHEDULE 4.10 attached hereto contains a list of all "employee
    pension benefit plans" (as defined in Section 3(2) of ERISA) (sometimes
    referred to herein as "Pension Plans"), "employee welfare benefit plans"

    insurance coverage (including, without limitation, self-insured
    arrangements), workers' compensation, disability benefits, supplemental
    unemployment benefits, vacation benefits or retirement

                                          15
<PAGE>

    benefits, or for profit sharing, deferred compensation, bonuses, incentive
    compensation or post-retirement insurance, compensation or benefits,
    maintained or contributed to by the Operating Entities or any other person
    or entity that, together with the Operating Entities, is treated as a
    single employer under Section 414(b), (c), (m) or (o) of the Code (the
    Operating Entities and each such other person or entity, a "Commonly
    Controlled Entity"), for the benefit of any current or former employees,
    officers or directors of the Operating Entities or dependents of any such
    person (collectively, "Benefit Plans").  The Operating Entities have
    delivered or made available to Buyer, its counsel, representatives or
    advisors, true, complete and correct copies of (i) each Benefit Plan (or,
    in the case of any unwritten Benefit Plans, descriptions thereof), (ii) the
    most recent annual report on Form 5500 filed with the Internal Revenue
    Service with respect to each Benefit Plan (if any such report was
    required), (iii) the most recent summary plan description for each Benefit
    Plan for which such summary plan description is required, (iv) each trust
    agreement and group annuity contract relating to any Benefit Plan and (v)

    material respects in accordance with its terms, or (B) any failure by the
    Operating Entities or any Benefit Plan to comply in all material respects,
    or any failure of any Benefit Plan to be operated and administered in all
    material respects, in accordance with the applicable provisions of ERISA
    and the Code."  Except as disclosed in SCHEDULE 4.10 attached hereto, no
    Operating Entity or Commonly Controlled Entity has, within one (1) year
    before the date of this Agreement, announced or otherwise made any
    commitment to create or amend any Benefit Plan.

         (i)  Except as disclosed in SCHEDULE 4.10 attached hereto, all Pension
    Plans intended to qualify under Section 401(a) of the Code have been the
    subject of determination letters from the Internal Revenue Service to the
    effect that such Pension Plans are qualified and exempt from Federal income
    taxes under Section 401(a) and 501(a), respectively, of the Code, and no
    such determination letter has been revoked nor has any such Pension Plan
    been amended since the date of its most recent determination letter or
    application therefor in any respect, and no event has occurred that would
    adversely affect its qualification or materially increase its costs in a
    manner which would constitute a Material Adverse Effect.  Except as
    disclosed on SCHEDULE 4.10, there have been no violations of ERISA or the
    Code which could have a Material Adverse Effect with respect to the filing
    of applicable documents, notices or reports (including, without limitation,
    annual reports filed on IRS Form 5500) relating to any Benefit Plan
    maintained by the Operating Entities or any Commonly Controlled Entity with
    any governmental authority or the furnishing of such required documents to
    the participants or beneficiaries of such Benefit Plans.

<PAGE>

         (ii) Neither the Operating Entities nor any Commonly Controlled Entity
    has within the five (5) year period immediately preceding the date hereof
    maintained, contributed to or been obligated to contribute to any Benefit
    Plan that is subject to Title IV of ERISA or Section 412 of the Code.
    Neither the Operating Entities nor any Commonly Controlled Entity is
    required to contribute to any "multiemployer plan" (as defined in Section
    4001(a) (3) of ERISA) or has withdrawn from any multiemployer plan where
    such withdrawal has resulted or would result in any "withdrawal liability"
    (within the meaning of Section 4201 of ERISA) that has not been fully paid.

        (iii) With respect to any Benefit Plan that is an employee welfare
    benefit plan, except as disclosed in SCHEDULE 4.10 attached hereto, (1) no
    such Benefit Plan is funded through a "welfare benefits fund", as such term
    is defined in Section 419 (e) of the Code, (2) each such Benefit Plan that
    is a "group health plan", as such term is defined in Section 5000 (b)(1) of
    the Code, complies substantially with the applicable requirements of
    Section 4980B(f) of the Code and (3) except as provided in writing in such
    plan, there are no understandings, agreements or undertakings, written or
    oral, that would prevent any such plan (including any such plan covering
    retirees or other former employees) from being amended or terminated
    without liability to the Operating Entities or any Subsidiary on or at any
    time after the Closing Date which could constitute a Material Adverse
    Effect.  Except as set forth in SCHEDULE 4.10 attached hereto, no Benefit
    Plan that is a welfare benefit plan provides for post-retirement medical or
    life insurance benefits coverage to any current or former employee,
    officer, or director of the Operating Entities or any dependent of any such
    individual except as may be required under Section 4980B of the Code.

         (iv) Except as set forth in SCHEDULE 2.2(b), no employee, officer or
    director of the Operating Entities or any other person will be entitled to
    any additional compensation or benefits or any acceleration of the time of
    payment or vesting of any compensation or benefits under any Benefit Plan
    as a result of the transactions contemplated by this Agreement.

         (v)  Except as set forth in SCHEDULE 4.10, all contributions due and
    payable on or before the Closing Date in respect of any Benefit Plan will
    or have been made in full and proper form, or adequate accruals have been
    provided for in the financial statements referred to in Section 4.5, in
    accordance with GAAP, for all other contributions or amounts in respect of
    the Benefit Plans for periods ending on the Closing Date, pursuant to
    routine administrative procedures or, in the case of any contributory
    Benefit Plan, amounts have been or will be contributed to such Benefit Plan
    within the time prescribed by the Code, ERISA, or any regulations
    thereunder or interpretations thereof by the Internal Revenue Service or
    the Department of Labor.

                                          17
<PAGE>

         (vi) As of the date hereof and the Closing Date, except as set forth
    in SCHEDULE 4.10 there are no actions, suits, disputes, arbitrations or
    claims pending (other than routine claims for benefits) and the Operating
    Entities have received no notice of any legal, administrative or other
    proceedings or governmental investigations pending or, to the knowledge of
    the Sellers, threatened against any Benefit Plan or against the assets of
    any Benefit Plan.

            (viii) Sellers shall not be deemed to have breached the
    representations and warranties of this Section 4.10(c) solely on account of
    an assertion by the Internal Revenue Service that the termination in
    accordance with Section 8.1(q) of this Agreement of any Benefit Plan
    intended to qualify under Section 401(k) of the Code fails to qualify under
    Section 401(k)(10)(A)(i) of the Code.

 .10 PAYMENT OF TAXES; DISTRIBUTIONS.  Each of the Operating Entities has timely
filed all Tax Returns required to have been filed by it and has paid or accrued
all Taxes due to any taxing authority with respect to all taxing periods ending
on or prior to the date hereof, and all such Tax Returns are true, correct and
complete in all material respects.  The Financial Statements and Interim
Statements include an adequate reserve for all Taxes not yet due or with respect
to which Tax Returns, as of the Closing, are not required to have been filed, in
each case to reflect the operations of the Sellers and Operating Entities
through the Closing.  Except as set forth in SCHEDULE 4.11, there is no pending
Tax audit, investigation or other proceeding by a governmental authority against
or affecting any of the Sellers and Operating Entities.  Each of the Sellers and
Operating Entities has (or before the Closing will have) filed true, correct and

shareholder of Sellers or any Operating Entity in his, her or its capacity as
such, which if decided adversely to Seller, such Operating Entity or such other
person, might reasonably be expected to have a Material Adverse Effect on any
Seller or any Operating Entity, or relates to the consummation of the
transactions or obligations contemplated hereby.  Sellers shall give prompt
notice to Buyer of any notice of, or other communication received by Sellers or
any Operating Entity relating to, a breach, default or event which, with notice
or lapse of time or both, would become a breach or default under any agreement,
indenture or instrument material to the financial condition, business,
properties, results of operations or prospects of Sellers or any Operating
Entity, and any notice or other communication from any third party or
governmental agency alleging that the consent or approval of such third party or
governmental agency is or may be required in connection with the transactions
contemplated by this Agreement.  Sellers shall promptly notify Buyer of the
occurrence, or non-occurrence, of any event the occurrence, or non-occurrence,
of which would be reasonably likely to cause any representation or warranty of
it contained in this Agreement to be untrue or inaccurate and any failure of it
to comply with or satisfy any covenant, condition or agreement to be complied
with or satisfied by it hereunder.  In addition, Sellers shall give prompt
notice to the Buyer of any facts or circumstances that arise or become evident
after the date of this Agreement and on or before the Closing Date which
reasonably could be expected to materially and adversely affect the business of
the Operating Entities, taken as a whole.

 .3  DISTRIBUTIONS AND ASSIGNMENTS.  The parties agree that, prior to the
Closing, the Sellers shall cause the Operating Entities to distribute to the
Shareholders (a) the sales/use tax refund claims and related claims against
equipment vendors (the "Vendor Sales Tax Claims") identified on SCHEDULE 6.4
attached hereto and (b) the stock or other ownership interests of each of the
Defunct Entities.  The parties agree that no Purchase Price adjustment shall be
effected in connection with such distributions.  The allocation of such
distributions shall be determined by the Sellers in their sole discretion, and
each of the Sellers agrees that Buyer shall have no responsibility therefor and
agrees, jointly and severally, to indemnify Buyer against any contrary claim by
any Seller or other third party.  Any Tax liability arising in connection with
such distribution shall be the sole responsibility of the Sellers, and each of
the Sellers, jointly and severally, agree to indemnify Buyer against any Tax
claim or liability asserted by any Tax authority.  Sellers represent and warrant
that the effect of the distributions contemplated by this Section 6.4 on the
balance sheets included within the Interim Statements referred to in Section 4.5
will not be significant.  To the extent that the Vendor Sales Tax Claims cannot
be resolved through cash payments made by the applicable vendors, and instead
such vendor(s) provide a credit to any of the Operating Entities in respect of
such claims, then, promptly following each realization upon such credits, Buyer
shall cause the applicable Operating Entities to pay the cash amount thereof to
the Sellers.

 .4  PRESS RELEASES.  Except as required by applicable law, none of the
Operating Entities nor any Seller shall give notice to third parties or
otherwise make any public statement or releases concerning this Agreement or the
transactions contemplated hereby except for such

                                          31
<PAGE>

written information as shall have been approved in writing as to form and
content by Buyer, which approval shall not be unreasonably withheld.

 .5  NO SHOP; NOTICE OF PROPOSALS.  Until the Closing Date or termination of
this Agreement, Sellers shall not directly or indirectly, solicit, initiate, or
encourage any inquiries or proposals that constitute, or could reasonably be
expected to lead to, a proposal or offer for a merger, consolidation, business
combination, sale of substantial assets, sale of partnership units, membership
units or shares of capital stock (including without limitation by way of a
tender offer) or similar transactions involving any of the Operating Entities,
other than the transactions contemplated by this Agreement (any of the foregoing
inquiries or proposals being referred to in this Agreement as an "Acquisition
Proposal"), engage in negotiations or discussions concerning, or provide any
non-public information to any person or entity relating to, any Acquisition
Proposal, or agree to, approve or recommend any Acquisition Proposal.  If after
the making of this Agreement any person or entity extends to Sellers any
Acquisition Proposal, or Sellers become aware of any Acquisition Proposal,
directly or indirectly, and regardless of the form of the transaction, or
Sellers become aware that any person or entity is seeking to conduct any
discussions with respect to any such matters, then in each such case Sellers
shall promptly notify Buyer of such information, including the identity of such
person or entity.  Without limiting the foregoing, it is understood that any
violation of the restrictions set forth in this Section 6.6 by any director,
officer, employee or affiliate of any Shareholder, Seller or Operating Entity or
any investment banker, financial advisor, attorney, accountant or other
representative of any Shareholder, Seller or Operating Entity shall be deemed to
be a breach of this Section 6.6 by the Sellers.

 .6  REASONABLE EFFORTS.  Subject to the terms and conditions hereof, Sellers
agree to use all of their reasonable efforts to take, or cause to be taken, to
do, or cause to be done, and to assist and cooperate with the Buyer in doing,
all things necessary, proper or advisable under applicable laws and regulations
to consummate and make effective, as soon as practicable, the transactions
contemplated by this Agreement.  Such actions shall include, without limitation,
(a) using reasonable efforts to obtain any consents, amendments to or waivers
under the terms of any Material Contracts that are required or advisable as a
result of the transactions contemplated by this Agreement, and (b) using
reasonable efforts to defend any lawsuits or other legal proceedings, whether
judicial or administrative and whether brought derivatively or on behalf of
third parties (including governmental agencies or officials), challenging this
Agreement or the consummation of the transactions contemplated hereby.  Subject
to the terms and conditions hereof, Sellers agree to use all its reasonable
efforts to take, or cause to be taken, all actions and to do, or cause to be
done, all things necessary to satisfy all the conditions of Closing set forth
herein at the earliest possible time.

 .7  SECTION 754 ELECTIONS. On or following the Closing, Buyer will cause a
Section 754 election to be made under the Code with respect to MCIC and
MCIC-HNI.  Sellers acknowledge and agree to such elections and further agree
that they will indemnify Buyer and hold Buyer harmless from and against any
claims, damages, losses and expenses

                                          32
<PAGE>

incurred as a result of any claim asserted by the joint venture partner in
MCIC-HNI as a result thereof.

Sellers, which approval shall not be unreasonably withheld.

 .1  REASONABLE EFFORTS.  From the date of this Agreement until the Closing
Date, subject to the terms and conditions hereof, Buyer agrees to use all its
reasonable efforts to take, or cause to be taken, to do, or cause to be done,
and to assist and cooperate with the Sellers in doing, all things necessary,
proper or advisable under applicable laws and regulations to consummate and make
effective, as soon as practicable, the transactions contemplated by this
Agreement.  Such actions shall include, without limitation, (a) using reasonable
efforts to obtain any consents, amendments to or waivers under the terms of any
material contracts, commitments or arrangements that are required as a result of
the transactions contemplated by this Agreement, and (b) using reasonable
efforts to defend any lawsuits or other legal proceedings, whether judicial or
administrative and whether brought derivatively or on behalf of third parties
(including governmental agencies or officials), challenging this Agreement or
the consummation of the transactions contemplated hereby.  Subject to the terms
and conditions hereof, Buyer agrees to use all its reasonable efforts to take,
or cause to be taken, all actions and to do, or cause to be done, all things
necessary to satisfy all the conditions of Closing set forth herein at the
earliest possible time.

 .2  CERTAIN TAX RETURNS.  Buyer shall, and Sellers acknowledge that Buyer
shall, be responsible for causing the preparation of all Tax Returns for MCIC
and MCLtd. which come due for filing after the Closing Date; provided, however,
that with respect to such Tax Returns that relate to any period prior to the
Closing Date, Sellers shall have an opportunity to review such Tax Returns and
such Tax Returns shall be subject to Sellers' consent, which consent shall not
be unreasonably withheld.  If Sellers' consent is reasonably withheld, Sellers
shall be entitled to prepare such Tax Returns at Sellers' expense (subject to
Buyer's review and consent, which consent shall not be unreasonably withheld).
Sellers shall not take any action inconsistent with this Section 7.3.  Buyer
shall make available upon reasonable request and at Sellers' expense, certain
books and records of the Operating Entities which are needed by or helpful to
the Sellers or any government agency in connection with Sellers' preparation of
the sales tax refund claims referred to in Sections 4.5(c) and 6.4 above and any
other tax issues, audits and governmental investigations affecting Sellers that
relate to any period prior to the Closing Date.

 .3  OFFICERS' AND DIRECTORS' INSURANCE; INDEMNIFICATION.

    ()   Buyer agrees to cause the Operating Entities (i) not to change, for
seven (7) years after the Closing Date, the provisions of any of the Operating
Entities charter documents or applicable indemnification agreements in effect on
the date hereof (the "Indemnification Agreements") in each case relating to
indemnification of each present or former director, officer or employee of the
Operating Entities (together with any successor by operation of law,
individually a "Seller Indemnified Party" and collectively the "Seller
Indemnified Parties") in a manner which adversely affects the rights of such
Seller Indemnified Party to indemnification thereunder and (ii) to perform its
obligations thereunder, or exercise any discretionary authority thereunder, to
the fullest extent permissible by law to provide such Seller Indemnified Party
with all rights to indemnification available thereunder.  Notwithstanding the
foregoing, nothing in this Agreement shall constitute a waiver of, or otherwise
operate to adversely affect, the existing rights of the Seller Indemnified
Parties under the Indemnification Agreements relating to the indemnification of
any Seller Indemnified Party.  Nothing in this Section shall preclude Buyer from
restructuring any of the Operating Entities as long as the indemnification
obligations remain effective against the applicable Operating Entity or its
legal successor.

    (a)  Buyer agrees to cause the Operating Entities to maintain for seven (7)
years after the Closing Date, any officers' and directors' liability insurance
policies currently in place indemnifying and holding harmless the Seller
Indemnified Parties with respect to any actions or omissions occurring prior to
the Closing Date, on terms no less advantageous to the Seller Indemnified
Parties than the Operating Entities' existing policies.  Notwithstanding the
foregoing, no Operating Entity shall be obligated to pay more than the most
recent annual premium payment (subject to annual increase in the same percentage
as increases in a national consumer price index selected by Buyer in good faith)
to maintain such insurance coverage, and Buyer may elect to provide comparable
coverage for the Seller Indemnified Parties through another policy of insurance
maintained by Buyer or an affiliate of Buyer.

    (b)  This Section 7.4 shall survive the Closing, is intended to benefit
Sellers and each of the Seller Indemnified Parties (each of whom shall be
entitled to enforce this Section 7.4 against the Operating Entities) and shall
be binding on all successors and assigns of the Operating Entities, provided
that this paragraph shall not create any right in any person other than the
Seller Indemnified Parties and no such other person shall become a third party
beneficiary of this Agreement.  Notwithstanding anything in this Agreement to
the contrary, this Section 7.4 shall not provide to any Seller Indemnified Party
indemnification protections greater than that currently in effect and provided
by an Operating Entity.

<PAGE>

may be (collectively, the "Buyer Group"), harmless of, from and against any and
all loss, claim, damage, liability, penalty or other cost or expense, including,
without limitation, reasonable attorneys' fees and costs (collectively "Claims"
and individually "Claim"), incurred or sustained by the Buyer Group, or any of

    ()   a misrepresentation or breach by Sellers of any term, representation,
warranty, covenant or agreement of the Sellers contained in this Agreement or in
any Schedule, Exhibit or other document delivered by the Sellers pursuant to the
terms of this Agreement; or

9.4 hereof, Buyer agrees to defend, indemnify, and hold the Sellers and their
officers, directors, members, partners, employees, heirs, agents, accountants,

warranty, covenant or agreement of Buyer contained in this Agreement or in any
other document delivered pursuant to this Agreement by the Buyer;

    (a)  the filing (or failure to file) or payment (or non-payment) of Tax
Returns or Taxes of the Operating Entities, to the extent that such Tax Returns
or Taxes relate to the operations of the Operating Entities (i) following the
Closing or (ii) prior to the Closing, provided that Tax liability in connection
therewith has been properly accrued on financial statements delivered to Buyer
prior to the Closing Date; provided, however, that this clause (b) shall not

indemnification claim hereunder constitutes a breach or default of any provision
of this Agreement by Sellers;

                                          39
<PAGE>

    (b)  indebtedness and other obligations of the Operating Entities owing or
in existence as of the Closing, provided that the amount or existence thereof
does not constitute a breach or default of any provision of this Agreement by
Sellers; or

    (c)  the operation of the Operating Entities following the Closing,
provided that the matter that would otherwise give rise to an indemnification
claim hereunder does not constitute a breach or default of any provision of this
Agreement by Sellers.

 .2  PAYMENT.  Subject to the limitations set forth in Section 9.4, upon the
determination by Sellers and Buyer, or absent their mutual agreement, by the
decision of a court of competent jurisdiction, of the amount of any liability
for any Claim, the Indemnifying Party (as defined in Section 9.5) shall pay to
the Indemnified Party (also as defined in Section 9.5), within ten (10) days
after such determination, the amount of any Claim.

 .3  LIMITATIONS ON INDEMNIFICATION.  The provisions set forth in Article IX
shall not be subject to any time limitations generally governing this Agreement,
except as specifically set forth in this Section 9.4 as follows:

    ()   TIME LIMITATION.  (i) The indemnification obligations of Buyer
contained in Section 9.2(a) shall expire on January 1, 1999 and the
indemnification obligations of Buyer contained in Section 9.2(b), (c) and (d)
shall have no time limitation, except that the indemnity obligations arising out
of the breach by Buyer of its covenant contained in Section 7.4 shall survive
for seven (7) years from the Closing Date, and (ii) the indemnification
obligations of Sellers contained in Section 9.1 shall expire on January 1, 1999,
except for the indemnity obligations arising out of a breach by Sellers of any
representation and warranty contained in Section 4.1 (Existence and Good
Standing), Section 4.2 (Authority), Section 4.3 (Capitalization) and Section
4.11 (Taxes) (collectively, the "Excluded Claims"), which shall have no time
limitation.  The foregoing limitations shall not apply with respect to those
pending Claims for indemnification for which written notice was given by the
Indemnified Party to the Indemnifying Party on or prior to January 1, 1999,
which written notice shall have the effect of continuing the applicable
indemnity obligations until such Claim(s) are resolved and all required payments
in respect thereof, as applicable, are made.

    (a)  DOLLAR LIMITATIONS.  Except with respect to Excluded Claims (with
respect to which there will be no "basket"), Buyer shall not be entitled to
indemnification from Sellers, and Sellers shall not be required to pay to Buyer
for, any Claims unless and until the aggregate amount of all Claims exceeds One
Hundred Thirty Thousand Dollars ($130,000) (the "Basket Amount").  In the event
Buyer's Claims exceed the Basket Amount, Buyer shall be entitled to
indemnification for such Claims in excess of the Basket Amount; PROVIDED,
FURTHER, that Sellers' aggregate liability for any Claims by Buyer (i.e., the
amount of such Claims in excess of the Basket Amount) shall in no event exceed
Two Million Dollars ($2,000,000) (the "Basket Cap"), except as to Excluded
Claims which shall not be subject to the Basket Cap.  By way of example, if the
aggregate Claims (not including Excluded

                                          40
<PAGE>

Claims) by Buyer were Two Million One Hundred Thirty Thousand Dollars
($2,130,000), then Sellers would be liable to Buyer for Two Million Dollars
($2,000,000) of such Claims (i.e., the aggregate amount thereof less the Basket
Amount).  Further, the aggregate amount that Buyer shall be entitled to recover
from Sellers for any of the Excluded Claims pursuant to this Section 9.4 shall
not exceed Thirteen Million Dollars ($13,000,000) minus any amounts previously
recovered by Buyer from Sellers in connection with any of the Claims that are
subject to the Basket Cap.  Notwithstanding the above or anything else in this
Agreement to the contrary, (i) the Basket Amount shall not apply to any known
issues or Claims relating to regulatory matters identified in writing by Buyer
to Sellers on or prior to the date hereof, (ii) any Claims in respect thereof
shall not be subject to or count toward the aggregate dollar limitation on
recoverable Claims pursuant to this paragraph, and (iii) any Claims in respect
thereof shall not be subject to any time limitation.

    (b)  OTHER LIMITATIONS.  Notwithstanding anything contained in this Article
IX to the contrary, (i) neither Sellers nor Buyer shall be liable for punitive
damages and (ii) neither Sellers nor Buyer shall be entitled to recover more
than once for any loss that may have resulted from the breach of any
representation or warranty or the breach of any covenant or agreement hereunder.

 .4  CLAIM PROCEDURE.  A person entitled to indemnification hereunder
("Indemnified Party") shall promptly give the indemnifying party (an
"Indemnifying Party") written notice of any matter which such Indemnified Party
has determined has given rise to a right of indemnification under this
Agreement, stating the amount of the Claim, if known, and method of computation
thereof, all with reasonable particularity (subject to the last sentence of this
paragraph).  The obligations and liabilities of any party under this Article IX
with respect to Claims arising from claims, assertions, events or proceedings of
any third party (including, without limitation, claims by any assignee or
successor of the Indemnified Party or any governmental agency), which are
subject to the indemnification provided for in this Article IX ("Third Party
Claims") shall be governed by and be subject to the following additional terms
and conditions:  if any Indemnified Party shall receive written notice of any
Third Party Claim, the Indemnified Party shall give the Indemnifying Party
prompt written notice of such Third Party Claim (subject to the last sentence of
this paragraph) and shall permit the Indemnifying Party, at its option, to
participate in the defense of such Third Party Claim by counsel of its own
choosing and at its expense.  Furthermore, if the Indemnifying Party
acknowledges in writing its obligation to indemnify the Indemnified Party
hereunder against any loss (without limitation) that may result from such Third
Party Claim, then the Indemnifying Party shall be entitled, at its option, to
assume and control the defense against such Third Party Claim at its expense and
through counsel of its choice if it gives prompt written notice of its intention
to do so to the Indemnified Party unless, in the reasonable opinion of counsel
for the Indemnified Party, there is a conflict or a potential conflict of
interests between the Indemnified Party and the Indemnifying Party in such
action, suit or proceeding, in which event the Indemnified Party shall be
entitled to direct the defense with respect to, but only with respect to, those
issues with respect to which such conflict exists.  In the event the
Indemnifying Party exercises its right to undertake the defense against any

                                          41
<PAGE>

such Third Party Claim as provided above, the Indemnified Party shall, and it
shall cause its affiliates to, cooperate with the Indemnifying Party in such
defense and make available to the Indemnifying Party all pertinent records,
materials and information in their possession or under their control relating
thereto as is required by the Indemnifying Party.  No such Third Party Claim,
except the settlement thereof which involves (i) the payment of money only for
which any Indemnifying Party is totally indemnified (without limitation) by the
Indemnifying Party and (ii) the unconditional release from all related liability
of the Indemnified Party, may be settled by the Indemnifying Party without the
written consent of the Indemnified Party.  Any settlement of a Third Party Claim
by an Indemnified Party without the written consent of the Indemnifying Party
shall discharge the Indemnifying Party from all liability hereunder with respect
to the subject matter of such Third Party Claim.  The foregoing notwithstanding,
the failure of any Indemnified Party to give any notice required to be given
hereunder shall not affect such Indemnified Party's right to indemnification
hereunder except to the extent the Indemnifying Party from whom such indemnity
is sought shall have been actually and materially prejudiced in its ability to
defend the claim or action for which such indemnification is sought by reason of
such failure.

 .5  OBLIGATION TO DEFEND.

    ()   The Indemnifying Party agrees, unless it assumes the defenses of any
Claim hereunder pursuant to Section 9.5, to pay the Indemnified Party's actual,
out of pocket costs of defending any Claim, including, without limitation,
attorneys' and paralegal fees, accountants' fees, witness fees, and court costs,
promptly after written demand therefor is given by the Indemnified Party to the
Indemnifying Party.

    (a)  If the Indemnifying Party undertakes the defense of any Claim pursuant
to Section 9.5, then so long as the Indemnifying Party, in good faith, is
contesting or defending the Claim: (i) the Indemnified Party may not admit any
liability with respect thereto, or settle, compromise, pay, or discharge the
same without the prior written consent of the Indemnifying Party, which consent
shall not be unreasonably withheld; (ii) the Indemnified Party agrees to
cooperate with the Indemnifying Party in the contest or defense of the Claim;
(iii) subject to Section 9.5, the Indemnified Party agrees to accept any
settlement of the Claim, provided that settlement is effected by monetary
payment or arrangements for monetary payment adequate to the Indemnified Party's
reasonable satisfaction, are made by the Indemnifying Party; and (iv) the
Indemnifying Party will provide the Indemnified Party with all information
regarding the contest or defense of the Claim and allow counsel for the
Indemnified Party to monitor, at the Indemnified Party's sole expense, all
proceedings in connection with the Claim.

 .6  EXCLUSIVE REMEDY.  The indemnification provisions of this Article IX and in
the Shareholder Consents will constitute the exclusive remedies of the parties
arising by virtue of a breach of any representation, warranty, agreement or
covenant under this Agreement unless Sellers or any person included within the
definition of "Knowledge of Sellers" made any knowingly false representation or
intentional misrepresentation with respect to any

                                          42

material fact contained in any representation or warranty set forth in this
Agreement or knowingly prevented Buyer from discovering the actual facts or
knowingly concealed the actual facts, relating to any representation or warranty
set forth in this Agreement, in which case Buyer shall be entitled to seek all
relief to which it is entitled under applicable law.  Except as provided in the
prior sentence and Article X, and without limiting the generality of the
preceding sentence, the parties shall have no right to rescind, abrogate,
terminate or abandon this Agreement.

    (d)  DROP DEAD DATE.  By Buyer or Sellers if the Closing shall not have

occur by such date is due to the failure of the Buyer or the Sellers to perform
or comply with its or their respective representations, warranties, covenants or
obligations and conditions precedent under this Agreement, then the
non-breaching party(ies) shall have the right and option to extend the Closing
Date for an additional 30 days by notifying the breaching party(ies) in writing
of such election to extend).

 .1  EFFECT OF TERMINATION.  In the event of the termination of this Agreement
according to its terms, this Agreement shall thereafter become void and have no
effect and no party hereto shall have any liability to any other party hereto or
its stockholders or directors or officers in respect thereof, except that each
party shall preserve any rights and remedies that it may have against a party
hereunder as a result of such party's breach of this Agreement.
