or any Subsidiary consistent with current practice, and obligations under
contracts that are terminable on thirty days' or less written notice without
penalty or premium.

3.12.     Taxes.
          -----

          (a) MMA, RTS and each Subsidiary has paid or caused to be paid all
federal, state, local, foreign, and other taxes, government fees or the like,
including, without limitation, income taxes, estimated taxes, alternative
minimum taxes, franchise taxes, capital stock taxes, unincorporated business
taxes, sales taxes, use taxes, ad valorem or value added taxes, employment and
payroll-related taxes, withholding taxes, property taxes and transfer taxes,
whether or not measured in whole or in part by net income, and all deficiencies,
or other additions to tax, interest, fines and penalties (including, without
limitation, all penalties relating to information reporting) owed by it
(collectively, "Taxes" and, each individually, a "Tax"), required to be paid by
it through the date hereof, whether disputed or not. Unpaid Taxes of RTS are
accrued quarterly on their respective financial books and records in accordance
with GAAP and there are no unpaid Taxes of the Subsidiaries. All Taxes required
to be withheld by MMA, RTS or any Subsidiary including, but not limited to,
Taxes arising as a result of payments or allocations (including guaranteed
payments) to foreign persons or to employees of MMA, RTS or any Subsidiary have
been collected and withheld, and have either been paid to the respective
governmental agencies, set aside in accounts for such purpose, or accrued,
reserved against, and entered on the financial books and records of MMA, RTS or
the Subsidiaries (as the case may be).

          (b) MMA, RTS and each Subsidiary has, in accordance with applicable
law, filed all federal, state, local and foreign Tax returns (including all
schedules thereto) required to be filed by it, and all such returns, to the
knowledge of MMA and Sellers, correctly and accurately set forth the amount of
any Taxes relating to the applicable period. No Seller has or will, on a Tax
return of the Seller, treat a partnership Tax item of MMA in a manner
inconsistent with the treatment of such item on a Tax return of MMA. A list of
all federal, state, local and foreign income Tax returns filed with respect to
MMA, RTS and each Subsidiary for taxable periods ended on or after December 31,
1995, is set forth in Schedule 3.12, and said Schedule indicates those returns
                      -------------
that have been audited or subject to administrative or judicial proceedings or
currently are the subject of an audit or administrative or judicial proceeding.
For each taxable period of MMA, RTS and each Subsidiary ended on or after
December 31, 1995, MMA has delivered to MMA Buyer correct and complete copies of
all federal, state, local and foreign income Tax returns, examination reports
and statements of deficiencies assessed against or agreed to by MMA, RTS and
each Subsidiary. Sellers will arrange for the preparation and timely filing of
the final partnership Tax returns for the final taxable year of MMA ending on
the

                                       15
<PAGE>

Closing Date (including any required Internal Revenue Service ("IRS") Form 8308)
and supplying required tax information to MMA, any such filings shall be
complete and correct, and Sellers shall arrange for the timely payment of any
amounts shown or required to be shown as due thereon.

          (c) Neither the IRS nor any other Governmental Authority responsible
for the imposition or collection of any Tax (a "Taxing Authority") is now
asserting or, to the knowledge of MMA and Sellers, threatening to assert against
MMA, RTS or any Subsidiary any deficiency or claim for additional Taxes or to
initiate any examination or proceedings with respect to any partnership Tax
items. No claim has ever been made by a Taxing Authority in a jurisdiction where
MMA, RTS or any Subsidiary does not file reports and returns that any of them
(or any of the Sellers, by reason of their investment in MMA) is or may be
subject to taxation by that jurisdiction. There are no liens or security
interests (unrecorded or recorded) on any of the assets of MMA, RTS or any
Subsidiary that arose in connection with any failure (or alleged failure) by
MMA, RTS, any Subsidiary or any of the Sellers to pay any Taxes. None of MMA,
RTS or any Subsidiary has ever entered into a settlement or closing agreement
with the IRS or any comparable agreement with any other Taxing Authority.

          (d) No extension of time with respect to any date on which a Tax
return was or is to be filed by MMA, RTS or any Subsidiary is currently in
effect, and no waiver or agreement by MMA, RTS or any Subsidiary is currently in
effect for an extension of time for the assessment or payment of any Taxes or
adjustment of any partnership Tax items.

          (e) MMA has never been (nor has it ever had any liability for unpaid
Taxes because it once was) a member of an "affiliated group" (as defined in
Section 1504(a) of the Internal Revenue Code of 1986, as amended (the "Code")).
None of RTS or the Subsidiaries has ever been (nor has RTS or the Subsidiaries
ever had any liability for unpaid Taxes because it once was) a member of an
"affiliated group" (as defined in Section 1504(a) of the Code. None of MMA, RTS
or the Subsidiaries has ever filed, nor have they ever been required to file, a
consolidated, combined or unitary tax return with any other entity, other than
tax returns with each other. None of MMA, RTS or the Subsidiaries is a party to
any tax sharing agreement.

3.13.     Loans; Accounts Receivable.
          --------------------------

          All of the loans extended by RTS are listed on Schedule 3.13 and are
                                                         -------------
valid and enforceable in accordance with their respective terms and subject to
no setoff or counterclaim.  None of MMA, RTS and each Subsidiary has any
accounts receivable or loans receivable from any person, firm or corporation or
other entity which is affiliated with MMA, RTS or any Subsidiary or from any
director, officer or employee of MMA, RTS or any Subsidiary except as disclosed
in Schedule 3.13.  Nothing in this Section 3.13 is intended as a representation
   -------------                   ------------
or warranty as to the creditworthiness of any borrower or guarantor or the
current value or collectibility of any loan.

or any direct or indirect redemption, purchase or other acquisition of the
Interests, Stock or Subsidiary Stock other than distributions and dividends made
by RTS in the ordinary course and consistent with past practices;

          (h) any change in the compensation payable or to become payable by
MMA, RTS or any Subsidiary to any of its representatives, employees, agents or
independent contractors other than (x) normal increases in accordance with its
usual practices or (y) any non-recurring bonus payment or arrangement made to or
with any of such representatives, employees, agents or independent contractors;

                                       17
<PAGE>

          (i) any obligation or liability incurred by MMA, RTS or any Subsidiary
to any of its representatives, employees, or any Seller or Stockholder or any

good repair.

          (m) any agreement or understanding, whether in writing or otherwise,
for MMA, RTS or any Subsidiary to take any of the actions specified in
paragraphs (a) through (l) above.

3.15.     Ordinary Course.
          ---------------

          Except as otherwise specifically contemplated by this Agreement, since
December 31, 1998 to the date hereof, each of MMA, RTS and RSI has conducted its
business only in the ordinary course and consistently with its prior practices
and RIB has not engaged in active business.

3.16.     Banking Relations.
          -----------------

          All of the arrangements which MMA, RTS, each Subsidiary and each Fund
has with any banking institution are, in all material respects, accurately
described in Schedule 3.16, indicating with respect to each of such arrangements
             -------------
the type of arrangement maintained (such as checking account or borrowing

          (b) The business of MMA, RTS or any Subsidiary does not, to the
knowledge of MMA and Sellers, infringe any rights of any other person in

infringement of any Intellectual Property of any other person has been filed or,
to the knowledge of MMA and Sellers, is threatened to be filed. None of MMA, RTS
or the Subsidiaries or, to the knowledge of MMA and Sellers, any of their
respective employees have any agreements or arrangements with any person related

such employee's ability to engage in business activities of any nature. The
activities of the employees on behalf of MMA, RTS or any Subsidiary do not
violate any such agreements or arrangements known to MMA or Sellers.

rule or regulation), in which MMA, RTS or any Subsidiary is a party, or to the
knowledge of MMA and Sellers, with which any of them is threatened.  There are

<PAGE>

each duly registered, licensed and qualified as a transfer agent in all
jurisdictions where such registration, licensing or qualification is required in
order to conduct its business, except where the failure to be so registered,
licensed or qualified would not have an MMA Material Adverse Effect. MMA, RTS
and each Subsidiary is, and, since its inception, has been, and all of their
real properties and other assets are currently, except for any material non-
compliance prior to the date hereof which has been cured, in compliance in all
material respects with all applicable federal, state and local laws, rules,
regulations, codes, ordinances and orders. MMA has delivered to MMA Buyer true

The information contained in such forms was true and complete at the time of

or revocation of the registration of MMA as an investment adviser, RIB as a
broker-dealer or MMA or RTS as a transfer agent (as the case may be), and to the

franchises, certifications and other approvals (collectively, the "Licenses")
required from, and has filed all reports required by, Governmental Authorities
in order for it to conduct the businesses presently conducted by MMA (as
investment adviser and transfer agent), RTS or any Subsidiary (as the case may
be) in the manner presently conducted by them and to own, use and operate its
properties in the manner currently owned, used and operated, except for any such
Licenses which are required solely by reason of Buyers' participation in the
transactions contemplated hereby. None of MMA, RTS or the Subsidiaries is

which would have an MMA Material Adverse Effect.

          (b) Except as set forth in Schedule 3.19, neither MMA, RTS nor any of

similar undertaking to, or is subject to any order or directive by, or has
adopted by board resolutions at the request of (each, whether or not set forth
in Schedule 3.19, a "Regulatory Agreement"), any Governmental Authority that
   -------------

capital adequacy, its credit policies, its management or its business, nor has
MMA, RTS or any of its Subsidiaries been advised by

                                       20
<PAGE>

any Governmental Authority that it is considering issuing or requesting any
Regulatory Agreement.

3.20.     Insurance.
          ---------

          RTS has in full force and effect such insurance as is customarily
maintained by companies of similar size in the same or a similar business with
respect to its business, properties and assets and each of MMA, RTS and the
Subsidiaries has in full force and effect such insurance and bonds as are

   -------------
under any such insurance policy.

          ------------------------------------

          Except as set forth in Schedule 3.22, none of MMA, RTS, the
                                 -------------
Subsidiaries, any employee of any of them (as the case may be), any Seller or
Stockholder, or, to the knowledge of MMA and Sellers, any of their respective
spouses or family members, is a party to any material transaction or material
contract or arrangement with MMA, RTS or any Subsidiary or owns directly or
indirectly on an individual or joint basis any interest (excluding passive
investments in the shares of any enterprise which are publicly traded provided

and family members, do not exceed five percent (5%) of the outstanding shares or
comparable interest in such entity) in, or serves as an officer or director or
in another similar capacity of, any competitor or client of MMA, RTS or any
Subsidiary or any organization which has a material contract or arrangement with
MMA, RTS or any Subsidiary.

has been maintained (as defined below) by MMA, RTS or any Subsidiary at any time
during the three-year period ending on the date of the Closing.

          (b) Each Employee Program which has been maintained by MMA, RTS or any
Subsidiary during the past seven years and which has at any time been intended
to qualify under Section 401(a) or 501(c)(9) of the Code has received a
favorable determination or approval letter from the IRS regarding its
qualification under such section and no such determination or approval letter
has been revoked nor, to the knowledge of MMA and Sellers, is there any reason
for such revocation from the effective date of such Employee Program through and
including the

                                       21
<PAGE>

Closing (or, if earlier, the date that all of such Employee Program's assets
were distributed). No event or omission has occurred which would cause any such
Employee Program to lose its qualification under the applicable Code section.

          (c) Neither MMA nor Sellers knows or has reason to know of any failure
of any party to comply in any material respect with any laws applicable to the
Employee Programs that have been maintained by MMA, RTS or any Subsidiary. To
the knowledge of MMA and Sellers, each Employee Program that has been maintained
by MMA, RTS or any Subsidiary has been maintained, operated and administered in
compliance in all material respects with its terms and with any related
documents or agreements. With respect to any Employee Program ever maintained by
MMA, RTS or any Subsidiary, there has occurred no "prohibited transaction," as
defined in Section 406 of the Employee Retirement Income Security Act of 1974,
as amended ("ERISA") or Section 4975 of the Code, or breach of any duty under
ERISA or other applicable law (including, without limitation, any health care
continuation requirements or any other tax law requirements, or conditions to
favorable tax treatment, applicable to such plan), which could result, directly
or indirectly, in any material taxes, penalties or other liability to Buyers,
MMA, RTS or any Subsidiary. No litigation, arbitration, or governmental
administrative proceeding (or investigation) or other proceeding (other than
those relating to routine claims for benefits) is pending or threatened with
respect to any such Employee Program.

          (d) All contributions to, and payments from, any Employee Program
maintained by MMA, RTS or any Subsidiary that may have been required in
accordance with the terms of such Employee Program have been timely made or are
properly accrued, to the extent required. Any insurance premium under any
insurance policy related to an Employee Program for any period up to and
including the Closing Date shall have been paid before the Closing Date.

          (e) None of MMA, RTS, any Subsidiary or any ERISA Affiliate (as
defined below) while an ERISA Affiliate (i) has, at any time after January 1,
1992, maintained any Employee Program which has been subject to Title IV of
ERISA (including, but not limited to, any Multiemployer Plan (as defined below))
or (ii) has ever provided health care or any other non-pension benefits to any
employees after their employment is terminated (other than as required by part 6
of subtitle B of title I of ERISA) or has ever promised to provide such post-
termination benefits that could impose a monetary obligation or material non-
monetary obligation after Closing upon Buyers, MMA, RTS or any Subsidiary.

          (f) With respect to each Employee Program maintained by MMA, RTS or
any Subsidiary within the three (3) years preceding the Closing, complete and
correct copies of the following documents (if applicable to such Employee
Program) have previously been delivered to MMA Buyer: (i) all documents
embodying or governing such Employee Program, and any funding medium for the
Employee Program (including, without limitation, trust agreements) as they may
have been amended; (ii) the most recent IRS determination or approval letter
with respect to such Employee Program under Code Sections 401 or 501(c)(9), and
any applications for determination or approval subsequently filed with the IRS;
(iii) the three (3) most recently

                                       22
<PAGE>

filed IRS Forms 5500, with all applicable schedules and accountants' opinions
attached thereto; (iv) the summary plan description for such Employee Program
(or other descriptions of such Employee Program provided to employees) and all
modifications thereto; (v) any insurance policy (including any fiduciary
liability insurance policy) related to such Employee Program; (vi) any documents
evidencing any loan to an Employee Program that is a leveraged employee stock
ownership plan; and (vii) all other materials reasonably necessary for MMA Buyer
to perform any of its responsibilities with respect to any Employee Program
subsequent to the Closing (including, without limitation, health care
continuation requirements).

          (g) Each Employee Program listed on Schedule 3.23 may be amended,
                                              -------------
terminated, modified or otherwise revised by MMA, RTS or any Subsidiary (as the
case may be) subject to compliance with applicable law.

          (h) For purposes of this section:

                 (i) "Employee Program" means (A) all employee benefit plans
within the meaning of ERISA Section 3(3), including, but not limited to,
multiple employer welfare arrangements (within the meaning of ERISA Section
3(4)), plans to which more than one unaffiliated employer contributes and
employee benefit plans (such as foreign or excess benefit plans) which are not
subject to ERISA; and (B) all stock option plans, bonus or incentive award
plans, severance pay policies or agreements, deferred compensation agreements,
supplemental income arrangements, vacation plans, and all other employee benefit
plans, agreements, and arrangements not described in (A) above. In the case of
an Employee Program funded through an organization described in Code Section
501(c)(9), each reference to such Employee Program shall include a reference to
such organization.

                 (ii) An entity "maintains" an Employee Program if such entity
sponsors, contributes to, or provides (or has promised to provide) benefits
under such Employee Program, or has any obligation (by agreement or under
applicable law) to contribute to or provide benefits under such Employee
Program, or if such Employee Program provides benefits to or otherwise covers
employees of such entity, or their spouses, dependents, or beneficiaries.

                 (iii) An entity is an "ERISA Affiliate" of MMA, RTS or any
Subsidiary during any period in which it is, or was, considered a single
employer with MMA, RTS or any Subsidiary under ERISA Section 4001(b) or part of
the same "controlled group" as MMA, RTS or any Subsidiary for purposes of Code
Section 414 or ERISA Section 302(d)(8)(C).

                 (iv) "Multiemployer Plan" shall have the meaning set forth in
ERISA Section 3(37).

3.28.     Additional Representations and Warranties relating to each Fund.
          ---------------------------------------------------------------

          (a) Since inception, each Fund has been and continues to be a duly
registered investment company in material compliance with the Investment Company
Act and the rules and regulations promulgated thereunder and duly registered or
licensed and in good standing under the laws of each jurisdiction in which such
qualification is necessary. To the knowledge of MMA and Sellers, each Fund,
since its inception, has been, except for any material non-compliance prior to
the date hereof which has been cured, in compliance in all material respects
with all applicable federal and state laws, rules, regulations and orders,
except as set forth on Schedule 3.28(a). Since their initial offering, shares of
                       ----------------
each Fund have been duly qualified for sale under the securities laws of each
jurisdiction in which they have been sold or offered for sale at such time or
times during which such qualification was required except where the failure to
be so registered or licensed would not have an MMA Material Adverse Effect. The
offering and sale of shares of each Fund have been registered under the
Securities Act of 1933, as amended (the "Securities Act"), during such period or
periods for which such registration is required, the related registration
statement has become effective under the Securities Act, no stop order
suspending the effectiveness of such registration statement has been issued and
no proceedings for that purpose have been instituted or, to the knowledge of MMA
and Sellers, are contemplated. As the same pertain to each Fund, to the
knowledge of MMA and Sellers, the registration statement of the Fund under the
Investment Company Act and/or the Securities Act has, at all times when such
registration statement was effective, complied in all material respects with the
requirements of the Investment Company Act and the Securities Act then in effect
and

                                       25
<PAGE>

neither such registration statement nor any amendments thereto contained at the
time such registration statement became effective and during which time that the
registration statement was in use, an untrue statement of a material fact or
omitted to state a material fact required to be stated therein or necessary to
make the statements therein, in the light of the circumstances under which they
were made, not misleading. Copies of the current registration statement of each
Fund under the Investment Company Act and/or the Securities Act which was filed
____________, 199_, (the "Registration Statement") have been made available to
MMA Buyer. All shares of each Fund were sold pursuant to an effective
registration statement to the extent required by the Securities Act and have
been duly authorized and, when issued, were validly issued, fully-paid and non-
assessable against each Fund. Each Fund's investments made since inception have
been made in all material respects in accordance with its investment objective,
investment policies and restrictions set forth in its registration statement in
effect at the time the investments were made (except where any violation of the
foregoing has been cured and the Fund has been made whole for any resulting
losses) and have been held in accordance with its respective investment policies
and restrictions, to the extent applicable and in effect at the time such
investments were held.

          (b) As to each Fund, there has been in full force and effect an
investment advisory agreement at all times since the inception of each Fund.
Each agreement pursuant to which MMA, RTS or any Subsidiary has received
compensation respecting its activities in connection with each Fund was duly
approved and has been duly renewed in accordance with the applicable provisions
of the Investment Company Act.

          (c) Except as set forth on Schedule 3.28(c), there are no special
                                     ----------------
restrictions, consent judgments or SEC or judicial orders on or with regard to
any Fund currently in effect.

          (d) Since its inception, each Fund has continuously elected and
qualified to be treated as a "regulated investment company" under Subsection M
of the Code and has continuously been eligible to compute, and has for each
taxable year computed, its federal income tax under Section 852 of the Code.
None of MMA, RTS, any Subsidiary or, to the knowledge of MMA and Sellers, any
Fund, has received any notice or other communication relating to or affecting
such status.

          (e) At the Closing Date, each Fund will have timely filed all Tax
returns, reports and other filings (including information returns, declarations
and reports) (the "Mutual Fund Tax Returns") required to be filed by it on or
before such date, any such Mutual Fund Tax Returns shall be, to the knowledge of
MMA and Sellers, complete and correct, and each Fund will have paid, or withheld
and paid over, all Taxes shown or required to be shown as due on such Mutual
Fund Tax Returns. No such Mutual Fund Tax Return is currently under audit, no
assessment has been asserted with respect to such Mutual Fund Tax Returns, and
no requests for waivers of the time to make any such assessment are pending.
None of the Funds is delinquent in the payment of any Tax, assessment or
governmental charge.

          (f) None of MMA, RTS, any Subsidiary or any person who is an
"affiliated person" (as defined in the Investment Company Act) or an "interested
person" (as defined in the Investment Company Act) of MMA, RTS or any
Subsidiary, receives or is entitled to receive any

                                       26
<PAGE>

compensation directly or indirectly (i) from any person in connection with the
purchase or sale of securities or other property to, from or on behalf of such
Fund, other than as broker in connection with the purchase or sale of securities
in compliance with Section 17(e) of the Investment Company Act and regulations
thereunder, or (ii) from any Fund or its security holders for other than bona
fide investment advisory, administrative or other services. Accurate and
complete disclosure of all such compensation arrangements has been made in the
Registration Statement filed under the federal securities laws.

          (g) MMA has made available to MMA Buyer correct and complete copies of
the audited financial statements, prepared in accordance with GAAP, of each Fund
for the past five fiscal years, and unaudited financial statements, prepared in
accordance with GAAP, of each Fund as of its most recent semi-annual stub period
(the "1999 Unaudited Financials") (each hereinafter referred to as a "Mutual
Fund Financial Statement"). Each of the Mutual Fund Financial Statements is
consistent with the books and records of such Fund, is complete and correct in
all material respects and presents fairly the financial position of such Fund in
accordance with GAAP applied on a consistent basis (except as otherwise noted
therein) at the respective date of such Mutual Fund Financial Statements and the
results of operations and cash flows for the respective periods indicated
(except in the case of the 1999 Unaudited Financials, the absence of footnotes
and customary year end adjustments). The Mutual Fund Financial Statements
reflect and disclose all material changes in accounting principles and practices
adopted by each Fund during the periods covered by each Mutual Fund Financial
Statement.

          (h) Except as set forth on Schedule 3.28(h), there is no litigation or
                                     ----------------
action, suit, proceeding or investigation at law or in equity pending or, to the
knowledge of MMA and Sellers, threatened in any court or before or by any
Governmental Authority, or before any arbitrator, by or against each Fund, or,
to the knowledge of MMA and Sellers, any officer or director thereof, MMA, RTS
or any Subsidiary relating to the activities of any Fund, that, if successful,
would result in any disqualification of MMA under Section 9(a) of the Investment
Company Act, or any event which would require MMA to give an affirmative
response to any of the questions in Item 11 of MMA's Form ADV (or any similar or
successor form) or Item 3 of the SEC Supplement to Form TA-1 (or any similar
successor form) or require an affirmative response from RIB under Item 7 of
RIB's Form BD (or any similar or successor form) or from RSI under Item 3 of the
SEC Supplement to Form TA-1 (or any similar successor form). There are no
judgments, injunctions, orders or other judicial or administrative mandates
outstanding against or affecting any Fund or, to the knowledge of MMA and
Sellers, any officer or director thereof relating to the activities of or
affecting any Fund.

          (i) Except as set forth on Schedule 3.28(i), to the knowledge of MMA
                                     ----------------
and Sellers, each Fund complies, and has been maintained in compliance, in all
material respects, with all applicable requirements, including all reporting and
disclosure requirements, prescribed by any and all applicable laws or
regulations and orders thereunder.

          (j) The exhibit list in the Registration Statement includes all of the
documents that would be required to be included thereon if such Registration
Statement were being refiled.

          (k) MMA has furnished to MMA Buyer, with respect to each Fund,
complete and correct copies of (i) Annual and Semi-Annual Reports and proxy
statements of the Fund pertaining to the last five years of the Fund, each in
the form delivered to the Fund's shareholders, as well as any additional report
or other material generally delivered to such shareholders since the delivery of
such Annual Report or Semi-Annual Report, as the case may be; (ii) all
Prospectuses, together with Statements of Additional Information of each Fund,
filed with the SEC in the last five years and (iii) all reports of each Fund on
Form N-SAR together with any and all exhibits annexed thereto from the last five
years of each Fund; each in the form filed with the SEC (all of the foregoing
documents referred to in (i), (ii) and (iii) being collectively referred to
herein as the "Fund Statements"). To the knowledge of MMA and Sellers, the
information contained in the Fund Statements does not contain any untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary in order to make any material statement made
therein, in light of the circumstances, not misleading. The financial
statements, including, without limitation, the Statement of Assets and
Liabilities, the Statement of Operations and the Statement of Changes in Net
Assets, and the notes thereto set forth in any such Annual or Semi-Annual Report
fairly present the financial position of each Fund as at the dates of such
statements and the results of its operations for the periods covered thereby in
accordance with GAAP consistently applied (except as noted therein). Since the
end of the period covered by any such Annual or Semi-Annual Report, there has
occurred no event or condition which would (i) require any Fund to file an
additional amendment, registration statement, prospectus, prospectus supplement,
report or other document with the SEC, which document has not been so filed with
the SEC and delivered to Buyers or (ii) require any Fund to conduct a meeting of
its shareholders, in each case other than with respect to the transactions
contemplated by this Agreement.

each Fund to the date hereof, no event or development has occurred that has had

Fund) nor any Fund has:

complaints from a governmental or regulatory authority or a self-regulatory
body, investigations or hearings (or communications indicating that the same may

to its attention which would, in any manner, challenge, prevent, alter or
materially delay any of the transactions contemplated hereby, and MMA will keep

breach or default had such event occurred or been known to MMA, RTS or Sellers
prior to the date hereof, of any of the representations, warranties or covenants
of MMA, RTS or Sellers contained in or referred to in this Agreement or any
Schedule or Exhibit referred to in this Agreement, in which case MMA shall give
detailed written notice thereof to MMA Buyer and MMA, RTS and Sellers shall use
its and their respective commercially reasonable efforts to prevent or promptly
remedy the same, and (iii) the status of regulatory applications, third party

prevent, alter or materially delay any of the transactions contemplated hereby,
and MMA Buyer will keep MMA fully informed with respect to such events, (ii) any
event which would cause or constitute a breach or default, or would have caused
or constituted a breach or default had such event occurred or been known to
Buyers prior to the date hereof, of any of the representations, warranties or
covenants of Buyers or FBR contained in or referred to in this Agreement or any
Schedule or Exhibit referred to in this Agreement, in which case MMA Buyer shall
give detailed written notice thereof to MMA and Buyers shall use their
commercially reasonable efforts to prevent or promptly remedy the same, and
(iii) the status of regulatory applications, third party consents, shareholder
approvals and registration amendments required pursuant to Article VI or any
application or notice to or filing with the OTS or other banking authority. MMA
Buyer shall also provide to MMA prior to the filing all proposed applications
and other documents and material responses that it intends to file with any
Governmental Authority relating to any of the transactions contemplated by this
Agreement, together with copies of any responses, comments, denials or approvals
issued by any Governmental Authority

                                       36
<PAGE>

shall obligate MMA Buyer to provide to MMA any confidential information to be
filed or filed with the OTS or any other banking authority, such as MMA Buyer's
business plan for RTS or the financial or biographical information of any
management official or senior executive of MMA Buyer, FBR or any of their
affiliates.


7.2.      Access.
          ------

          MMA, RTS and the Subsidiaries shall upon reasonable notice afford
(and, with respect to the Funds, shall use its best efforts to make available)
to Buyers and their representatives such access during normal business hours
throughout the period prior to the Closing Date to MMA's, RTS's and each
Subsidiary's books, records and Owned and Leased Real Estate and each Fund's
books, records, properties, and to such other information as MMA Buyer may
reasonably request that pertain to the operation of MMA, RTS, each Subsidiary or
each Fund, provided, such access does not unreasonably interfere with the
business of MMA, RTS, each Subsidiary or each Fund.  Without limiting the
foregoing, MMA acknowledges that MMA Buyer shall make requests necessary to
afford MMA Buyer the opportunity to complete its due diligence review of the
operations, books and records of the Funds.

7.3.      Information.
          -----------

          Each of Buyers, MMA (on behalf of itself and the Subsidiaries) and RTS
shall hold, and shall cause its respective directors, officers, employees,
agents, consultants and advisors to hold, in strict confidence, unless
disclosure to a regulatory authority is necessary in connection with any
necessary regulatory approval or unless compelled to disclose by judicial or
administrative process or by other requirement of law or the applicable
requirements of any regulatory agency or relevant stock exchange, all nonpublic
records, books, contracts, instruments, computer data and other data and
information (collectively, the "Information") concerning Buyers, MMA, RTS, the
Subsidiaries or the Funds furnished to Buyers or MMA (as the case may be) by the
other or the Funds or their respective representatives pursuant to this
Agreement (except to the extent that such information can be shown to have been
(a) previously known by such party on a non-confidential basis, (b) in the
public domain through no fault of such party or (c) later lawfully acquired from
other sources by the party to which it was furnished), and none of Buyers, MMA
(on behalf of itself and the Subsidiaries) or RTS (as the case may be) shall
release or disclose such Information to any other person, except its auditors,
attorneys, financial advisors, other consultants and advisors and, to the extent
permitted above, regulatory authorities.  In the event of the termination of
this Agreement, each of Buyers, MMA (on behalf of itself and the Subsidiaries)
and RTS shall return to the other party or destroy all information furnished to
it and its representatives and all analyses, compilations, data, studies other
documents prepared by them or their representatives containing or based in whole
or in part on any such furnished information (including information reflecting
MMA Buyer's review of each Fund).  Neither Sellers on one hand nor Buyers on the
other hand shall, directly or indirectly, defame, disparage, make derogatory
statements about or attempt knowingly to create

                                       37
<PAGE>

any negative inference regarding the business of MMA, RTS, Sellers, the Funds or
Buyers and their respective affiliates.

7.4.      Qualification of each Fund.
          --------------------------

          Subject to applicable fiduciary duties of the Board of
Directors/Trustees of the Funds to each Fund, MMA will use its commercially
reasonable efforts to cause each Fund to take no action (i) that would prevent
each Fund from qualifying as a "regulated investment company", within the
meaning of Section 851 of the Code or being eligible to compute its income under
Section 852 of the Code or so computing its income, or (ii) that would be
inconsistent with each Fund's prospectus and other offering, advertising and
marketing materials.

7.5.      Forms.
          -----

          Prior to the Closing, MMA and RTS shall, and MMA shall cause the
Subsidiaries to, cooperate with MMA Buyer in the preparation and filing of all
forms and amendments to forms, including, without limitation, Forms ADV, BD and
TA-1 of MMA Buyer to be filed with federal agencies and self-regulatory
organizations and the state securities commissions, and all other documents
required to be filed or delivered under applicable federal and state laws, and
regulations promulgated thereunder, including, without limitation, the Advisers
Act and the Exchange Act and applicable related state acts and insurance laws,
as a result of the consummation of the transactions contemplated by this
Agreement and in order to put MMA Buyer in the position to operate the business
of MMA, RTS and RIB after the Closing Date in the same manner as they are
currently conducting business.  Each of MMA and RTS shall use, and MMA shall
cause RIB to use, its respective commercially reasonable efforts to obtain as
promptly as practicable all licenses, permits, approvals and authorizations, and
to complete all applications and make all filings necessary (subject to MMA
Buyer's prior approval) to (i) enable MMA Buyer to operate the business of MMA,
RTS and RIB and shall provide MMA Buyer with copies of all such materials prior
to submission and a reasonable opportunity to comment thereon and (ii) prepare
RIB's registration and license under the Exchange Act and state laws as a
broker-dealer and maintain RIB's membership in the NASD.  In this regard, MMA
shall provide on Schedule 7.5 a list of all states and other jurisdictions where
                 ------------
RIB is registered or otherwise qualified to conduct business as a broker-dealer.
After the Closing, MMA Buyer will maintain in good condition all presently
existing books, records, files and documents of MMA for the time periods and in
the locations required by the Advisers Act and the rules thereunder including,
without limitation, Rule 204-2, or by Governmental Authorities.

7.6.      Exclusivity.
          -----------

          None of MMA (on behalf of itself and the Subsidiaries), RTS, or the
Sellers will accept, negotiate, solicit, initiate or encourage the submission of
any proposal or offer from any person other than Buyers relating to the
acquisition of all or substantially all of the Interests, Stock, Subsidiary
Stock or assets of MMA, RTS or the Subsidiaries (including any acquisition
structured as a merger, consolidation, or share exchange).  Each of MMA and
Sellers shall

                                       38
<PAGE>

promptly notify MMA Buyer of the terms of any such proposal or offer and provide
to MMA Buyer a copy of any written offer or proposal with respect to the
foregoing prior to the Closing Date.

7.7.      Taxes.
          -----

          (a) Each Seller shall be liable for all transfer taxes which are due
as a result of his, her or its transfer of Interests and/or Stock pursuant to
this Agreement.

          (b) Sellers shall cause MMA not to amend any Tax return (including any
schedule thereto) filed as of the date of this Agreement, unless required by
applicable law and disclosed in Schedule 3.12 (as such schedule may be amended
at any time prior to the Closing Date by notice to Buyers). Sellers, on behalf
of MMA, shall prepare and file the final partnership Tax returns for the final
taxable year of MMA ending on the Closing Date required to be filed after the
date hereof in a manner that such returns shall be consistent with returns for
prior years.

          (c) Sellers shall cause MMA to make a timely election under Code
Section 754 to adjust the basis of partnership property in the manner provided
in Code Sections 734 and 743 for the final taxable year of MMA ending on the
Closing Date, and, in doing so, to include with the final partnership Tax
returns of MMA for such final year any "Section 754 Forms" that are required to
be so included on account of the election under Code Section 754. Sellers and
Buyers shall cooperate fully, and in good faith, with each other in making this
election, determining the fair market value of each asset of MMA and allocating
the Purchase Price for the Interests among those assets in accordance with
Sections 755 and 1060(d) of the Code. "Section 754 Forms" shall mean all
returns, documents, statements, and other forms that are required to be
submitted to the IRS in connection with a Code Section 754 election made by a
partnership with respect to which there has been an applicable asset acquisition
within the meaning of Code Section 1060(d), and any analogous forms that are
required to be filed for state or local tax purposes.

          (d) Any failure by Buyers to withhold monies from the Purchase Price
for the Interests that results in Taxes being assessed against Buyers shall be
treated as taxes for which Buyers are entitled to indemnification pursuant to
this Agreement.

          (e) In no event will Buyers or any of their affiliates be responsible
for any Tax liability that arises as a result of the transfer of Interests or
Stock pursuant to this Agreement, including any state or local Tax liability
resulting in connection with such transfer; any such liability shall be the
responsibility of Sellers.

7.8.      Waiver.
          ------

          Each Seller waives any and all rights under the Partnership Agreement,
including, but not limited to rights of first refusal ("ROFR") and tag along
rights ("TAR").  In addition, Seller waives any and all notice provisions and
waiting periods contemplated by the Partnership

                                       39
<PAGE>

Agreement including, but not limited to such notice provisions and waiting
periods associated with the ROFR, TAR and sale of partnership provisions.

commercially reasonable efforts to promptly prepare and file all necessary
documentation, to effect all applications, notices, petitions and filings, to
obtain as promptly as practicable all permits, consents, approvals and
authorizations of all third parties and Governmental Authorities that are
necessary or advisable to consummate the transactions contemplated by this
Agreement and to comply with the terms and conditions of all such permits,
consents, approvals and authorizations of all such Governmental Authorities.

          (b) Except as limited by Section 7.1(b), MMA shall have the right to
                                   -------------
review in advance all the information relating to MMA and its Subsidiaries that
appears in any filing made with, or written materials submitted to, any third
party or any Governmental Authority in connection with the transactions
contemplated by this Agreement. In exercising the foregoing right, MMA shall act
reasonably and as promptly as practicable. The parties hereto agree that they
will consult with each other with respect to the obtaining of all permits,
consents, approvals and authorizations of all third parties and Governmental
Authorities necessary or advisable to consummate the transactions contemplated
by this Agreement and each party will keep the other apprised of the status of
matters relating to completion of the transactions contemplated herein.

          (c) MMA and Buyers shall, upon request, furnish each other with all
information concerning itself, its Subsidiaries, representatives, stockholders,
partners and affiliates and such other matters as may be reasonably necessary or
advisable in connection with any other statement, filing, notice or application
made by or on behalf of Buyers, MMA, RTS or any Subsidiary to any Governmental
Authority in connection with the transactions contemplated by this Agreement.

          (d) MMA Buyer and MMA shall promptly advise each other upon receiving
any communication from any Governmental Authority whose consent or approval is
required for consummation of the transactions contemplated by this Agreement
which causes such party to believe that there is a reasonable likelihood that
any regulatory approval will not be obtained or that the receipt of any such
approval will be materially delayed.

7.10.     Proxy Statement.
          ----------------

          Prior to mailing to the shareholders of each Fund, MMA Buyer and MMA
shall prepare proxy materials which are subject to regulation under the Exchange
Act or the Investment Company Act and which are to be used for any shareholders'
meeting directly or indirectly relating to the transaction.  MMA Buyer and MMA
shall use their best efforts to finalize the proxy statement to their mutual
satisfaction.  If the requisite percentage of shareholders of each Fund fails to
approve any one or more of the proposals for which approval was being sought at
the shareholder meeting, and any adjournment thereof, MMA Buyer may, in

                                       40
<PAGE>

its sole discretion, elect in writing within five days after the failure to
approve, time being of the essence, not to consummate the transaction and
terminate this Agreement. If MMA Buyer timely elects to terminate this Agreement
as provided herein, no party shall have any liability to the other hereunder.

7.11.     Press Releases, Etc.
          --------------------

          MMA Buyer and MMA shall consult with each other as to the form,
substance and timing of any press release or other public disclosure of matters
related to this Agreement or any of the transactions contemplated hereby and no
such press release or other public disclosure shall be made without the consent
of the other party or parties, which shall not be unreasonably withheld or
delayed; provided, however, that the parties may make such disclosures as are
required by law after making reasonable efforts in the circumstances to consult
in advance with the other parties.

7.12.     Minority Stock.
          --------------

          The General Partner shall use its good faith efforts to acquire as
promptly as practicable the Minority Stock of the Additional Stockholders.  In
the event that the General Partner has not acquired all of the Minority Stock
owned by the Additional Stockholders within three months after the date hereof,
then at the request of MMA Buyer, MMA shall cause RTS to undertake a reverse
merger, reverse stock split or similar action, to the extent not prohibited by
applicable law, to convert the Minority Stock then owned by Additional
Stockholders to a right to receive cash or dissenter or appraisal rights.

7.13.     Tax Cooperation.
          ---------------

          Buyers and Sellers shall reasonably cooperate with each other in
connection with the preparation of Tax returns (including the Mutual Fund Tax
Returns) of MMA, RTS, the Subsidiaries and the Funds and MMA, RTS, RIB or the
Sellers (on behalf of RSI and themselves) shall preserve all information,
returns, books, records and documents relating to any liabilities for Taxes with
respect to a taxable period until the later of the expiration of all applicable
statutes of limitation and extensions thereof, or a final determination with
respect to Taxes for such period and shall not destroy or otherwise dispose of
any record without first providing the other party with a reasonable opportunity
to review and copy the same.

7.14.     Name Change.
          -----------

          In the event of termination of this Agreement, as soon as practicable,
each Buyer shall change its name so that it no longer contains any reference to
the name "Money Management Associates."

8.1.      Conditions to Each Party's Obligations to Consummate.
          ----------------------------------------------------

          The respective obligations of each party to consummate the
transactions contemplated by this Agreement shall be subject to the fulfillment

          (a) Regulatory Approvals. The transactions contemplated by this
              ---------------------
Agreement shall have been approved by all Governmental Authorities, the approval

any non-standard condition or requirement of any non-standard commitment which
is unreasonably burdensome in the reasonable judgment of the parties hereto; and
all waiting periods arising under applicable law shall have duly lapsed or been
terminated.

          (b) No Orders. None of Buyers, MMA, RTS, any Subsidiary or any Fund
              ---------
shall be subject to any order, decree or injunction of a court or agency of
competent jurisdiction which enjoins or prohibits the consummation of any of the
transactions contemplated by this Agreement or prevents MMA Buyer from operating
the business of MMA, RTS and the Subsidiaries upon Closing in the same manner as
the business is currently operating.

          (c) Litigation. No action or proceeding shall have been instituted or
              -----------
threatened by any court, Governmental Authority, self-regulatory body or other
person or entity and remain pending before any court, governmental body or self-
regulatory body or be threatened, to restrain or prohibit or to recover damages
in respect of any or all of the transactions contemplated by this Agreement
which is reasonably likely to have a Buyer Material Adverse Effect or an MMA
Material Adverse Effect (as the case may be) with respect to any of the parties
hereto, or would hinder MMA Buyer's ability to conduct the business of MMA, RTS
and RIB upon Closing in the same manner as the business is currently being
conducted; nor shall any Governmental Authority or other person or entity have
notified any party to this Agreement or any of its affiliates that consummation
of any or all of the transactions contemplated by this Agreement would
constitute a violation of the laws of any jurisdiction or that it intends to
commence any action or proceeding to restrain or prohibit or to recover damages
in respect of any or all of the transactions contemplated by this Agreement,

              -----------
party under this Agreement shall be net of (i) any amounts recovered or
recoverable by the indemnified party pursuant to any indemnification by or
indemnification agreement with any third party, other than any insurance policy,
and (ii) any insurance proceeds (net of associated incremental premiums)
available as an offset against such Losses.

     9.3.  Claims Procedures.
           -----------------

          (a) Notice. An indemnified party shall give written notice to an
              -------
indemnifying party promptly upon receipt of written notice or sixty (60) days
from discovery by the indemnified party of any claim, demand or cause of action
which may give rise to a claim for indemnification under this Agreement (a
"Claim") setting forth in detail all information that forms the basis of such
Claim. Except as otherwise set forth in Section 9.2(a) or (c), the failure to
                                        -------------     ---
give such notice shall not affect the right of the indemnified party to
indemnity hereunder except to the extent such failure has adversely affected the
rights of the indemnifying party.

          (b) Third Party Procedures. In the case of any Claim (other than a
              -----------------------
Claim by an indemnified party for a breach of representation or warranty with
respect to ownership/title as set forth in Sections 3.3, 3.9 or 4.1), the
                                           ------------  ---    ---
indemnified party may defend, settle or otherwise compromise, or pay a Claim
unless it shall have received notice (within thirty (30) days of the
indemnifying party's receipt of the notice of such Claim from the indemnified
party) from the indemnifying party that the indemnifying party either disputes
that it has indemnification responsibility relating to such Claim or it intends,
at its sole cost and expense, to assume the defense of any such matter, in which
latter case the indemnified party shall have the right, at no

                                       50
<PAGE>

cost or expense to the indemnifying party, to participate in such
defense; provided, that, any legal counsel selected by the indemnifying party
pursuant to this Section 9.3(b) shall be reasonably satisfactory to the
                 -------------
indemnified party; and provided, further, that the indemnifying party shall not,
in the defense of such Claim, consent to the entry of any judgment or enter into
any settlement, except with the written consent of the indemnified party (which
consent shall not be unreasonably withheld or delayed), which provides for
anything other than money damages or other money payments or which does not
include as an unconditional term thereof the giving by the claimant or the
plaintiff to the indemnified party a release from all liability in respect of
such Claim. If the indemnifying party does not assume the defense of a Claim or
dispute that it has indemnification responsibility with respect to such Claim
within the time period specified above, the indemnifying party shall pay all
costs of each indemnified party arising out of the defense until the defense is
assumed. The indemnified party shall take all appropriate action to permit and
authorize the indemnifying party fully to participate, to the extent provided
above, in the defense of any such Claim. The indemnifying party shall keep the
indemnified party fully apprised at all times as to the status of the defense.
If the indemnifying party does not assume the defense, the indemnified party
shall keep the indemnifying party reasonably apprised as to the status of the
defense. If the Claim is one that by its nature cannot be defended solely by the
indemnifying party, then the indemnified party shall make available such
information and assistance as the indemnifying party may reasonably request and
shall cooperate with the indemnifying party in such defense, at the expense of
the indemnifying party.

          (c) Indemnified Party Procedures. A party which has a Claim for
              -----------------------------
indemnification under this Article IX, other than as described in Section
                           ----------                             -------
9.3(b), shall promptly notify the other parties hereto of such Claim. If within
-----
thirty (30) days of the receipt of such notice of Claim, the parties cannot
agree on the amount of or responsibility for such Claim, the parties agree to
submit such dispute to binding arbitration to be held in Bethesda, Maryland
under the rules of the American Arbitration Association. Any such arbitration
shall be conducted by three arbitrators, one of whom shall be selected by the
Seller Representative, one of whom shall be selected by Buyers and one of whom
shall be selected by the arbitrators selected by the Seller Representative and
Buyers. The expenses of any such arbitration shall be paid by the non-prevailing
party as determined by the final order of the arbitrators.

          (d) Remedies. Absent fraud or criminal activity and except for
              --------
equitable remedies, the remedies provided for in this Article IX shall
                                                      ----------
constitute the sole and exclusive remedy of the parties hereto for any post-
Closing claims made for breach of this Agreement or the representations and
warranties contained herein or in connection with the transactions contemplated
hereby or any of the other matters covered by this Article IX. Nothing in this
                                                   -----------
subsection is intended to affect any rights under the Note, Escrow Agreement,
Deed of Trust or UCC-1 Financing Statement.

          (e) Satisfaction of Losses. Subject to the procedures set forth above,
              -----------------------
Losses shall be satisfied as follows:

                                       51
<PAGE>

                (i) Principal Sellers shall satisfy their liability for Losses
by paying the amount of such liability to the indemnified party or, at the
written election of either Buyers or Seller Representative, by offsetting such
amount against the outstanding balance of the Note; provided, however, that in
the event any such offset is elected by Seller Representative prior to the due
date of the next installment otherwise payable under the Note, the amount of
Loss to be offset shall be increased by the applicable "short-term rate" per
annum, compounded annually, from the date paid by the indemnified party to a
third party or payable to the indemnified party by virtue of a breach of
Sections 3.3, 3.9 or 4.1 up to the date of the next installment otherwise
------------  ---    ---
payable under the Note; and

                (ii) Buyers and MMA shall satisfy their liability for Losses by
paying the amount of such liability to the Seller Representative on behalf of
the Sellers.

an agreement in writing among the parties hereto and executed in the same manner

any covenant, representation or warranty of this Agreement in one instance shall

                                       55
<PAGE>

not operate as or be deemed to be construed as a further or continuing waiver of
any other breach of such term, condition, covenant, representation or warranty,
nor shall any failure or delay at any time or times to enforce or require
performance of any provision hereof operate as a waiver of or affect in any
manner such party's right at a later time to enforce or require performance of
such provision or of any provision hereof; provided, however, that no such
waiver, unless it, by its own terms, explicitly provides to the contrary, shall
be construed to effect a continuing waiver of the provision being waived and no
such waiver in any instance shall constitute a waiver in any other instance or

compliance.

such action or proceeding may be heard and determined in such state court or, to
the extent permitted by law, in such federal court.  Each of the parties hereby
irrevocably consents to the service of process in any such action or proceeding
by the mailing by certified mail of copies of any service or copies of the
summons and complaint and any other process to such party at the address

   11.11. Seller Representative.
          ---------------------

Representative"), as such Seller's representative, attorney-in-fact and agent,
with full power of substitution to act in the name, place and stead of such
Seller with respect to the transfer of such Seller's Interests to Buyers in
accordance with the terms and provisions of this Agreement and to act on behalf
of such Seller in any litigation or arbitration involving this Agreement and to
do or refrain from doing all such further acts and things, and to execute all
such documents, as such Seller Representative shall deem necessary or
appropriate in connection with any of the transactions contemplated under this
Agreement, including, without limitation, the power:

          (a) to act for such Seller with regard to matters pertaining to
indemnification referred to in this Agreement, including the power to compromise
any claim on behalf of such Seller, to bring and transact matters of litigation
and to refer matters to arbitration;

          (b) to receive, hold, and deliver to Buyers the Interests accompanied
by executed stock powers, signature guarantees, and any other documents relating
thereto on behalf of such Seller;

          (c) to execute and deliver all ancillary agreements, certificates,
statements, notices, approvals, extensions, waivers, undertakings, amendments
and other documents required or permitted to be given in connection with the
consummation of the transactions contemplated by this Agreement;

          (d) to receive funds and give receipt for funds including in respect
of the Purchase Price for the Interests for such Seller's Interests, to
distribute to the Seller their respective share of the Purchase Price for the
Interests and to withhold from such funds a contingency reserve for the matters
referred to below;

          (e) to give and receive all notices and communications to be given or
received under this Agreement and to receive service of process in connection
with any claims under this Agreement, including service of process in connection
with arbitration; and

          (f) to take all actions which under this Agreement may be taken by the
Seller Representative and to do or refrain from doing any further act or deed on
behalf of such Seller which Seller Representative deems necessary or appropriate
in his sole discretion relating to the subject matter of this Agreement as fully
and completely as such Seller could do if personally present.

          If Daniel L. O'Connor dies or otherwise becomes incapacitated and
unable to serve as Seller Representative, Martin O'Connor shall become Seller
Representative.  The death or incapacity of any Seller shall not terminate the
agency and power of attorney granted hereby

                                       57
<PAGE>

to the Seller Representative. The appointment of Seller Representative shall be
deemed coupled with an Interest and shall be irrevocable and MMA Buyer and any
other person may conclusively and absolutely rely, without inquiry, upon any
action of Seller Representative, as the action of such Seller in all matters
referred to herein. All actions, decisions and instructions of Seller
Representative shall be conclusive and binding upon all of the Sellers and no
Seller shall have any cause of action against Seller Representative for any
action taken or not taken by Seller Representative in his role as such, except
for any action or omission taken or made fraudulently or in bad faith with
respect to such Seller. All reasonable out-of-pocket fees and expenses
(including fees payable to counsel and other professional and brokerage fees)
incurred by Seller Representative in connection with performing such function
and in connection with the transactions contemplated hereby and all payments,
damages, costs, fees and expenses in connection with any indemnification claim
by or other dispute with MMA Buyer under the Agreement shall be paid by each
Seller in proportion to his respective Interests and may be deducted by Seller
Representative from any amounts otherwise payable to any Seller hereunder.
Seller Representative may withhold from funds received on behalf of each Seller
prior to distribution of such funds to each Seller any amount which Seller
Representative deems necessary as a reserve for any such fees, expenses and
indemnification claims.

   11.12. Title Insurance.
          ---------------

          The Sellers shall and shall cause MMA, RTS and the Subsidiaries to
cooperate with MMA Buyer in obtaining, a good and valid, irrevocable ALTA title
insurance commitment (the "Title Commitment") from a title insurance company
reasonably acceptable to MMA Buyer (the "Title Company"), irrevocably committing
the Title Company (subject only to the satisfaction of any industry standard
requirements contained in the Title Commitment and reasonably acceptable to MMA
Buyer) to issuing (i) an ALTA form of title insurance policy insuring good,
valid and marketable fee simple title to the Owned Real Estate in RTS, in the
amount that MMA Buyer reasonably requests prior to Closing, or (ii) a date down
and, if required by MMA Buyer, an increased amount endorsement to the existing
title insurance policy number 95080085 issued by Chicago Title Insurance
Company, subject, in either case, to no Liens or other exceptions to title other
than Permitted Exceptions (the "Title Policy") and insuring pedestrian and
vehicular access to and from one or more legally and physically open public
rights of way satisfactory to MMA Buyer, in its sole but reasonable discretion.
