                           CONTINGENT STOCK AGREEMENT

     This Contingent Stock Agreement, effective as of January 1, 1996, is by The
Rouse Company, a Maryland corporation (the "Company"), in favor of and for the
benefit of the Holders and the Representatives (as such terms are hereinafter
defined).

                             PRELIMINARY STATEMENTS

     1. The Company, TRC Acquisition Company I, a newly-formed Delaware
corporation and a wholly-owned subsidiary of the Company ("Newco"), and The
Hughes Corporation, a Delaware corporation ("THC"), are parties to that certain
Agreement and Plan of Merger dated as of February 22, 1996 (the "Merger
Agreement"), which provides, among other things, for the merger of THC with and
into Newco (the "Merger"), as a result of which each outstanding share of common
stock of THC (other than shares held by THC or any of its subsidiaries) will be
converted into the right to receive (i) upon the effectiveness of the Merger,
shares of Rouse Common Stock (as hereinafter defined) and, if required pursuant
to the terms of the Merger Agreement, cash and (ii) subsequent to the
effectiveness of the Merger, additional shares of Rouse Common Stock or, in
certain circumstances, Rouse Preferred Stock, pursuant to the terms of this
Agreement.

     2. The number of shares of Rouse Common Stock deliverable by the Company
upon the effectiveness of the Merger will be determined as provided in the
Merger Agreement. The number of shares of Rouse Common Stock deliverable by the
Company subsequent to the effectiveness of the Merger (the "Contingent Shares")
is not susceptible of being ascertained as of the time of the Merger because of
the uncertainty as to the value of certain Assets (as hereinafter defined) as of
the time of the Merger. Accordingly, the number of Contingent Shares will be
determined as provided in this Agreement based upon the future economic
performance of the Business Units (as hereinafter defined) and related Assets.

     3. It is a condition precedent to the obligations of THC to close the
transactions contemplated by the Merger Agreement that the Company shall have
executed and delivered this Agreement.

     4. This Agreement and the Merger Agreement are inter-related and
non-severable, and the parties to the Merger Agreement would not have
consummated the Merger had this Agreement not been executed and delivered and
vice versa.

     NOW, THEREFORE, in consideration of the premises and the covenants
contained herein and in the Merger Agreement, and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
Company, intending to be legally bound, hereby agrees as follows:

Summerlin Business Unit (the "Summerlin Business Unit Account") shall be
credited with an amount equal to the sum of the following:

     (a) an amount equal to 50% of Excess Cash Flow of the Summerlin Business
Unit for the applicable Computation Period until the aggregate credits to the
Summerlin Business Unit Account under this clause (a) for All Computation
Periods equal a cumulative 7.5% per annum, compounded semi-annually, amount
calculated on the Adjusted Net Equity Balance of the Summerlin Business Unit
Account as of the beginning of each Prior Computation Period;

     (b) an amount equal to 50% of (i) Excess Cash Flow for the Summerlin
Business Unit for the applicable Computation Period minus (ii) 200% of the
credits to the Summerlin Business Unit Account under clause (a) above for such
Computation Period, until the aggregate credits to the Summerlin Business Unit
Account under this clause (b) for All Computation Periods equal to 50% of the
Initial Net Equity of the Summerlin Business Unit;

     (c) an amount equal to 75% of (i) Excess Cash Flow for the Summerlin
Business Unit for the applicable Computation Period minus (ii) 200% of the
credits to the Summerlin Business Unit Account under clauses (a) and (b) above
for such Computation Period, until the aggregate credits to the Summerlin
Business Unit Account under this clause (c) for All Computation Periods equal
$40,000,000;

                                       18

<PAGE>

     (d) an amount equal to 25% of (i) Excess Cash Flow for the Summerlin
Business Unit for the applicable Computation Period minus (ii) the sum of (A)
200% of the credits to the Summerlin Business Unit Account under clauses (a) and

     Section 2.07. Asset Appraisals and Holders' FMV Allocation. (a) The Fair
Market Value of the Assets comprising each Business Unit or portion thereof
shall be determined by appraisal as of the Valuation Date with respect to such
Business Unit or portion thereof. If any of the Assets comprising any Business
Unit are held indirectly by the Company or any Business Unit Entity through any
other Person, the appraisal required under this Section 2.07 with respect to
such Assets shall determine the Fair Market Value of such Assets as owned by
such other Person, in which event the Fair Market Value of such Assets for
purposes of computing the number of Contingent Shares to be delivered by the
Company in connection with such Valuation Date shall be determined by
multiplying such Fair Market Value by the percentage interest in the equity of
such other Person owned by the Company or such Business Unit Entity, taking into
account any preferential rights associated with any Equity Interest owned by any
Person therein.

     (b) Within five days after the Valuation Date with respect to each Business
Unit or portion thereof, the Representatives and the Company shall each appoint
one appraiser for each item of Assets included in such Business Unit or portion
thereof. The two appraisers so appointed shall, within five days after the
second of them has been appointed, appoint a third appraiser and such appraisers
shall constitute the "Appraisal Panel" with respect to such item of Assets. If
the two appraisers appointed are unable to agree on the third appraiser within
such five-day period, either the Representatives or the Company may apply to any
court of competent jurisdiction for the appointment of a third appraiser. If
either the Representatives or the Company fails to appoint an appraiser within
five days after notice from the other that the recipient of such notice has
failed to appoint an appraiser within the five-day period referred to above, the
appraiser appointed by the other shall be deemed to constitute the Appraisal
Panel. Each appraiser shall be a real estate and financial expert who is
generally recognized as having current competence in the valuation of Assets
similar to the Assets being appraised in the area(s) where such Assets are
located. Each appraiser shall be independent and, as such, shall not be an
Associate of the Company or any Holder (other than as a result of contractual
relationships arising out of such appraisal or any prior appraisal pursuant to
this Agreement). The fees and expenses of each Appraisal Panel shall be paid by
the Company. Notwithstanding anything to the contrary set forth above, any
appraiser may be appointed to appraise more than one item of Assets at any one
time, or may be appointed repeatedly over time.

     (c) Each Appraisal Panel shall be instructed to determine, within 45 days
of its appointment, the Fair Market Value of the Assets comprising the relevant
Business Unit or portion thereof as of the relevant Valuation Date. If any
Appraisal Panel consists of three appraisers, the Fair Market Value
determination that shall differ the most from the second highest Fair Market
Value determination of all three appraisers shall be excluded, the remaining two
Fair Market Value determinations shall be averaged and such average shall
constitute the determination of the Appraisal Panel. Each Appraisal Panel shall
furnish the Company and the Representatives with a written report of its
determination within the 45-day period referred to above, which report shall (i)
be signed by each member of such Appraisal Panel and (ii) specify the amount
determined by such Appraisal Panel to be the Fair Market Value of the relevant
Assets as of the relevant Valuation Date. The determination of the Fair Market
Value of such Assets by the Appraisal Panel shall be final and binding on the
Parties.

     (d) Upon determining the Fair Market Value of the Assets comprising any
Business Unit or portion thereof, the aggregate Fair Market Value of all of the
Assets comprising such Business Unit or portion thereof shall be reduced by an
amount equal to the amount of all accounts payable and other indebtedness
properly reflected on the records and books of account of such Business Unit or
portion thereof in accordance with the terms

                                       19

<PAGE>

of this Agreement which have not been taken into account as an Expenditure in
determining the Excess Cash Flow for any Computation Period for the applicable
Business Unit Account of such Business Unit or portion thereof, excluding any
such amounts which were taken into account in determining the Fair Market Value
of any of such Assets (the "Adjusted Fair Market Value"). Upon determining the
Adjusted Fair Market Value of any Business Unit or portion thereof, an amount
equal to such Adjusted Fair Market Value shall be allocated between the Company
and the Holders in the same manner that credits to the Business Unit Account for
such Business Unit are calculated under Section 2.03, 2.04, 2.05 or 2.06 (as
appropriate), as if such Adjusted Fair Market Value were the Excess Cash Flow
upon which such calculations are to be made and taking into account all previous
credits which have been made to such Business Unit Account based upon Excess
Cash Flow for such Business Unit; provided, however, that (i) such allocations
shall be determined without regard to any development or management fee
otherwise payable to the Company or any of its Subsidiaries, other than any
General Business Unit Reduction Amount or Summerlin Business Unit Reduction
Amount (which for purposes of this paragraph (d) shall include 3% of the gross
proceeds from sales of real estate comprising the applicable Business Unit prior
to such Valuation Date irrespective of whether such proceeds have been received
by the Company or any of its Subsidiaries) which represents amounts actually
received by or owing to the Company or any of its Subsidiaries which have not
been taken into account under Section 2.03(c)(ii)(B) or 2.06(e)(ii)(D),
respectively, with regard to the sale, prior to the applicable Valuation Date,
of any real estate which comprised the General Business Unit or the Summerlin
Business Unit, and (ii) the amount determined to be allocable to the Holders as
provided above shall be reduced by an amount equal to 50% of the fees and
expenses of each Appraisal Panel which have been paid by the Company with
respect to such Business Unit or portion thereof. As used herein, "Holders' FMV
Allocation", when used with reference to the Assets comprising any Business Unit
or portion thereof, means the portion of the Adjusted Fair Market Value of such
Assets allocable to the account of the Holders pursuant to this paragraph (d).

     (e) For purposes of this Agreement, "Fair Market Value" means, with respect
to any Asset, the most probable price in terms of money which such Asset would
bring at a fair sale for its highest reasonable use, determined in a
commercially reasonable manner, and where the title to such Asset will pass from
the seller to the buyer with (i) each of the buyer and the seller acting
prudently and knowledgeably, (ii) the price not being affected by any undue
stimulus, (iii) neither the buyer nor seller being under compulsion to sell or
buy such Asset, (iv) each of the buyer and the seller being typically motivated,
well informed and advised and acting in what it considers to be its best
interests, (v) a reasonable period of time being allowed for exposure of such
Asset in the open market and (vi) the payment of the purchase price being made
in cash. In determining the Fair Market Value of any Asset, there shall be taken
into account, as appropriate, all Liabilities relating to such Asset to the
extent that they are secured by a Lien on such Asset or would otherwise encumber
such Asset in the hands of the buyer, and the appraisers shall assume that the
Asset being appraised is to be sold in a commercially reasonable manner.

     Section 2.08. Delivery of Contingent Shares. (a) The Company shall be
obligated to deliver Contingent Shares with respect to each Business Unit (i)
following each Calculation Date (including the Valuation Date for such Business
Unit) as provided in paragraph (b) below and (ii) following the Valuation Date
for such Business Unit or portion thereof as provided in paragraph (c) below.

     (b) The aggregate number of Contingent Shares to be delivered by the
Company to the Holders with respect to all of the Business Units following each
Calculation Date as contemplated by paragraph (a)(i) above shall be determined
as of such Calculation Date and shall be a number (the "Computation Period
Distribution Amount") equal to the product of (i) 0.992 times (ii) the sum of
(A) an amount equal to (x) the aggregate positive balances of the Business Unit
Accounts as of such Calculation Date divided by (y) the Current Share Value as
of such Calculation Date plus (B) an amount equal to (x) the Dividend Adjustment
with respect to the number of Contingent Shares determined under clause (A)
above divided by (y) the Current Share Value as of such Calculation Date. The
Company shall unconditionally and irrevocably deliver to each Holder (or his
designee), as soon as practicable and in any event within 60 days after each
Calculation Date, that number of Contingent Shares determined by multiplying (1)
the Computation Period Distribution Amount with respect to such Calculation Date
by (2) such Holder's Percentage Interest.

     (c) The aggregate number of Contingent Shares to be delivered by the
Company to the Holders with respect to any Business Unit or portion thereof as
contemplated by paragraph (a)(ii) above shall be determined as follows:

                                       20

<PAGE>

               (i) In the event that the Company delivers all of the Contingent
          Shares contemplated by paragraph (a)(ii) above with respect to any
          Business Unit or portion thereof in one installment, the aggregate
          number of Contingent Shares to be delivered by the Company shall be
          determined as of the Valuation Distribution Date for such Business
          Unit or portion thereof and shall be a number equal to the product of
          (A) 0.992 times (B) the sum of:

                    (x) an amount equal to (1) the Holders' FMV Allocation with
          respect to such Assets divided by (2) the Valuation Distribution Share
          Value as of the Valuation Distribution Date for such Business Unit or
          portion thereof plus

                    (y) an amount equal to (1) the Dividend Adjustment with
          respect to the number of Contingent Shares determined under clause (x)
          above divided by (2) the Valuation Distribution Share Value as of such
          Valuation Distribution Date.

               The Company shall unconditionally and irrevocably deliver to each
          Holder (or his designee), as soon as practicable and in any event
          within 12 months after the applicable Valuation Date, that number of
          Contingent Shares determined by multiplying (a) the aggregate number
          of Contingent Shares being delivered by the Company on such Valuation
          Distribution Date under this clause (i) by (b) such Holder's
          Percentage Interest.

               (ii) In the event that the Company delivers the Contingent Shares
          contemplated by paragraph (a)(ii) above with respect to any Business
          Unit or portion thereof in more than one installment, on each
          Valuation Distribution Date for such Business Unit or portion thereof,
          the "Holders' FMV Allocation Amount" shall be calculated, being an
          amount equal to the product of:

                    (A) the aggregate number of Contingent Shares being
          delivered by the Company on such Valuation Distribution Date times

                    (B) the Valuation Distribution Share Value with respect to
          such Valuation Distribution Date times

                    (C) a fraction, the numerator of which is such Valuation
          Distribution Share Value and the denominator of which is the sum of
          (x) such Valuation Distribution Share Value plus (y) the Dividend
          Adjustment with respect to one share of Rouse Common Stock during the
          period commencing on the applicable Valuation Date to and including
          such Valuation Distribution Date times

                    (D) 0.992.

               The Company shall continue to deliver Contingent Shares to the
          Holders with respect to such Business Unit or portion thereof pursuant
          to this clause (ii) until such time as the sum of the Holders' FMV
          Allocation Amount with respect to each Valuation Distribution Date for
          such Business Unit or portion thereof equals the Holders' FMV
          Allocation with respect to such Business Unit or portion thereof. In
          connection with each such Valuation Distribution Date, the Company
          shall unconditionally and irrevocably deliver to each Holder (or his
          designee) a number of Contingent Shares equal to the product of (1)
          the aggregate number of Contingent Shares being delivered by the
          Company on such Valuation Distribution Date under this clause (ii)
          times (2) such Holder's Percentage Interest. The Company shall
          unconditionally and irrevocably deliver to each Holder (or his
          designee), as soon as practicable and in any event within 12 months
          after the applicable Valuation Date, all Contingent Shares required to
          be delivered under paragraph (a)(ii) above with respect to each
          Business Unit or portion thereof.

     (d) In the event that the Company fails to deliver Contingent Shares on or
before the date on which the Company is obligated to deliver such Contingent
Shares, the Company shall become obligated to deliver to each Holder that number
of additional Contingent Shares which is equal to the quotient of (i) the
return, calculated at the Applicable Federal Rate plus 5%, on an amount equal to
(A) the number of Contingent Shares

                                       21

<PAGE>

which should have been delivered to such Holder times (B) the Current Share
Value utilized to determine the number of Contingent Shares to be delivered by
the Company in connection with the applicable Calculation Date, such return to
accrue on such amount for the period commencing on the day that such Contingent
Shares were required to be delivered by the Company to such Holder and
continuing thereafter until the Company delivers such Contingent Shares to such
Holder or delivers Contingent Preferred Shares to such Holder in accordance with
Section 4.16 divided by (ii) the Current Share Value utilized to determine the
number of Contingent Shares to be delivered by the Company in connection with
the applicable Calculation Date.

     (e) If an Event of Default shall have occurred and be continuing (other
than any Event of Default applicable under the circumstances described in
paragraph (f) below), the Representatives may, by notice in writing delivered to
the Company, (i) accelerate the Company's obligation to deliver Contingent
Shares pursuant to paragraph (c) above or (ii) require the Company, in
satisfaction of the Company's obligation to deliver Contingent Shares
thereafter, to issue and deliver to the Holders an aggregate number of
Contingent Preferred Shares (including fractional shares) determined by dividing
(A) the aggregate number of Contingent Shares which would otherwise be delivered
to the Holders pursuant to paragraph (c) above by (B) the quotient of (x) $100
divided by (y) the Current Share Value as of the date of such notice. Upon
receipt of such notice, the Company shall cause the appraisals described in
Section 2.07 to be initiated and completed as soon as practicable as of the
Calculation Date for the most recent Computation Period ended on or before the
date of such notice, and the Company shall unconditionally and irrevocably
deliver such Contingent Shares or Contingent Preferred Shares, as applicable, as
soon as practicable and in any event within 15 days after the completion of such
appraisals.

     (f) If (i) but for the provisions of Section 7.05(b), an Event of Default
described in clause (c) of the definition thereof would have occurred and be
continuing with respect to any Business Unit Entity solely on account of the
non-performance by the Company of any covenant contained in Section 4.10, 4.11,
4.12 or 4.13 as such covenant relates to such Business Unit Entity and (ii) in
connection with such circumstances, (A) the Company shall have determined in
good faith that it would neither be commercially reasonable nor in the best
interests of the Company and the Holders for the Company to take, or cause to be
taken, the actions necessary to avoid such non-performance and (B) the Company
shall have given prior written notice of such non-performance to the
Representatives confirming that the Company has made the determination described
in subclause (A) and setting forth, in reasonable detail, the reasons therefor,
then the Representatives may, by notice in writing delivered to the Company, (i)
accelerate the Company's obligation to deliver Contingent Shares pursuant to
paragraph (c) above with respect to the Assets comprising the Business Unit to
which such non-performance relates or (ii) require the Company, in satisfaction
of the Company's obligation to deliver Contingent Shares thereafter with respect
to the Assets comprising the Business Unit to which such non-performance
relates, to issue and deliver to the Holders an aggregate number of Contingent
Preferred Shares (including fractional shares) determined by dividing (A) the
aggregate number of Contingent Shares which would otherwise be delivered to the
Holders pursuant to paragraph (c) above by (B) the quotient of (x) $100 divided
by (y) the Current Share Value as of the date of such notice. Upon receipt of
such notice, the Company shall cause the appraisals described in Section 2.07 to
be initiated and completed with respect to such Assets as soon as practicable as
of the Calculation Date for the most recent Computation Period ended on or
before the date of such notice, and the Company shall unconditionally and
irrevocably deliver such Contingent Shares or Contingent Preferred Shares, as
applicable, as soon as practicable and in any event within 15 days after the
completion of such appraisals; provided, however, that in connection with any
appraisal conducted pursuant to this paragraph (f), the Appraisal Panel shall be
instructed to determine the Fair Market Value of the relevant Assets as if no
Person is required to make any additional contribution to the capital of, or
investment in, or loan or advance in respect of, such Assets.

     (g) If any foreclosure on, or the exercise of any similar remedy with
respect to, any of the Assets comprising any Business Unit shall occur or (i) an
Event of Default described in clause (e), (f), (g), (h), (i) or (j) of the
definition thereof shall have occurred and be continuing with respect to any
Business Unit Entity other than HHPLP, as if such clauses applied to each such
Business Unit Entity instead of the Company and HHPLP and (ii) if, in connection
with such Event of Default, (A) the Company shall have determined in good faith
that it would neither be commercially reasonable nor in the best interests of
the Company and the Holders for the Company to take, or cause to be taken, the
actions necessary to avoid such Event of Default and (B) the Company shall have
given prior written notice of such Event of Default to the Representatives
confirming that the Company has made the determination described in subclause
(A) and setting forth, in reasonable detail, the reasons therefor, then in any
such event the Representatives may, by notice in writing delivered to the
Company, (i) accelerate the Company's

                                       22

<PAGE>

obligation to deliver Contingent Shares pursuant to paragraph (c) above with
respect to any Assets comprising any Business Unit which are owned by such
Business Unit Entity or (ii) require the Company, in satisfaction of the
Company's obligation to deliver Contingent Shares thereafter with respect to any
Assets comprising any Business Unit which are owned by such Business Unit
Entity, to issue and deliver to the Holders an aggregate number of Contingent
Preferred Shares (including fractional shares) determined by dividing (A) the
aggregate number of Contingent Shares which would otherwise be delivered to the
Holders pursuant to paragraph (c) above by (B) the quotient of (x) $100 divided
by (y) the Current Share Value as of the date of such notice. Upon receipt of
such notice, the Company shall cause the appraisals described in Section 2.07 to
be initiated and completed with respect to such Assets as soon as practicable as
of the Calculation Date for the most recent Computation Period ended on or
before the date of such notice, and the Company shall unconditionally and
irrevocably deliver such Contingent Shares or Contingent Preferred Shares, as
applicable, as soon as practicable and in any event within 15 days after the
completion of such appraisals; provided, however, that in connection with any
appraisal conducted pursuant to this paragraph (g), the Appraisal Panel shall be
instructed to determine the Fair Market Value of the relevant Assets as if no
Person is required to make any additional contribution to the capital of, or
investment in, or loan or advance in respect of, such Assets.

     (h) Except as otherwise required by applicable tax Laws, in connection with
each delivery of Contingent Shares or Contingent Preferred Shares pursuant to
this Agreement, the Contingent Stock Distribution Value of each Holder shall be
discounted to the effective date hereof at the Contingent Stock Distribution
Discount Rate to determine the amount of contingent stock distribution principal
(the "Contingent Stock Distribution Principal") and the amount of Contingent
Stock Distribution Interest. Contingent Stock Distribution Interest shall be
treated by the Company and each Holder as interest for federal income tax
purposes.

     (i) All Contingent Shares to be delivered hereunder shall be newly-issued
shares of Rouse Common Stock or, at the election of the Company, Treasury
Shares; provided, however, that (i) in the event the Company is precluded or
otherwise unable, for any reason, to deliver newly-issued shares of Rouse Common
Stock to the Holders, the Company shall deliver or cause to be delivered
Treasury Shares to the Holders and (ii) in the event the Company is precluded or
otherwise unable, for any reason, to deliver Treasury Shares to the Holders, the
Company shall deliver or cause to be delivered newly-issued shares of Rouse
Common Stock to the Holders.

     (j) Notwithstanding anything to the contrary contained herein, at any time
at which the Company is obligated to deliver Contingent Shares to the Holders
pursuant to the terms of this Agreement, the Company shall not deliver any
fractional shares of Rouse Common Stock to any Holder and, in lieu of delivering
such fractional shares, the following provisions shall apply:

               (i) with respect to any fractional shares which would have
          otherwise been delivered by the Company to a Holder based upon Excess
          Cash Flow:

                    (A) if the last Calculation Date with respect to any
          Business Unit shall not have occurred, on the next succeeding
          Calculation Date the Company shall deliver to such Holder a number of
          Contingent Shares equal to the sum of (x) such number of fractional
          shares plus (y) the number of Contingent Shares which the Company is
          obligated to deliver to such Holder based upon Excess Cash Flow for
          the Computation Period ending on such succeeding Calculation Date plus
          (z) a number of Contingent Shares equal to (1) the Dividend Adjustment
          with respect to a share of Rouse Common Stock during the period
          commencing on the Calculation Date on which such fractional shares
          would have otherwise been delivered and ending on the date on which
          the Contingent Shares to be delivered by the Company in connection
          with such succeeding Calculation Date are actually delivered to the
          Holders multiplied by (2) the number of such fractional shares divided
          by (3) the Current Share Value utilized in determining the number of
          Contingent Shares to be delivered by the Company in connection with
          such succeeding Calculation Date; and

                    (B) if no Calculation Date with respect to any Business Unit
          or portion thereof will occur after such Calculation Date, the Company
          shall pay such Holder an amount in cash equal to such fractional
          shares times the Current Share Value utilized in determining the

                                       23

<PAGE>

          number of Contingent Shares to be delivered by the Company in
          connection with such Calculation Date; and

               (ii) with respect to any fractional shares which would otherwise
          have been delivered by the Company to the Holders in connection with
          any Valuation Date, the Company shall pay each Holder an amount in
          cash equal to (A) the number of fractional shares which would have
          otherwise been delivered by the Company to such Holder in connection
          with such Valuation Date times (B) the Valuation Distribution Share
          Value utilized in determining the number of Contingent Shares to be
          delivered by the Company to the Holders in connection with such
          Valuation Date.

     (k) Notwithstanding anything to the contrary contained in this Agreement,
in the event that the Company receives a Representatives' Diversion Notice in
accordance with the provisions of Section 5.10(b), the Company shall, in lieu of
delivering the number of Contingent Shares described in such Representatives'
Diversion Notice to the Holders, deliver such Contingent Shares to the
Representatives, in which event the number of Contingent Shares otherwise
deliverable to the Holders shall be appropriately reduced pro rata in accordance
with their respective Percentage Interests.

     Section 2.09. Debits to the Business Unit Accounts. Upon the delivery by
the Company to the Holders of all Contingent Shares required to be delivered in
connection with any Calculation Date, the Business Unit Account with respect to
which such Contingent Shares were delivered shall be debited by an amount equal
to the product of (i) the sum of the number of Contingent Shares so delivered by
the Company plus the aggregate number of fractional shares which were not
delivered to the Holders in accordance with the provisions of Section 2.08(j)
times (ii) the Current Share Value utilized in determining the number of
Contingent Shares delivered times (iii) 1.008.

     Section 2.10. Tax Adjustments. (a) The Company shall compute the pro forma
taxable income or loss for each Business Unit ("Business Unit Income or Loss")
for each taxable year, utilizing the method of tax accounting and, to the extent
applicable, the elections employed in the preparation of the consolidated
federal income tax return of the group of corporations of which the Company is
the common parent (the "Company Consolidated Group") for such taxable year.
Notwithstanding the form of ownership of a Business Unit, such computation shall
be made as though each Business Unit was a separate corporation filing a
separate return of taxable income which was taxed at the Applicable Tax Rate, as
determined with respect to such Business Unit. The Business Unit Income or Loss
for each Business Unit shall be computed utilizing the actual items of income,
gain, loss and deduction attributable to the Assets, Liabilities and operations
of such Business Unit; provided, however, that in making such computation, the
State and Local Tax Adjustment shall be taken as a deduction.

     (b) If such calculation results in a Business Unit Income or Loss which is
a loss for such taxable year, the Tax Adjustment for such year shall be zero and
such loss shall be carried forward and treated as an item of deduction that will
reduce any calculation of Business Unit Income or Loss of such Business Unit
which results in income in any future period in accordance with the principles
of Section 172(b) of the Code and the regulations promulgated thereunder. No
unutilized Business Unit Income or Loss which is a loss will be carried back to
any prior taxable year.

     (c) The Company shall estimate the Business Unit Income or Loss of each
Business Unit for each Computation Period and, based upon such estimates, shall
compute the estimated Tax Adjustment for such Computation Period for each
Business Unit (the "Computation Period Tax Adjustment"). In the event and to the
extent that the Tax Adjustment with respect to any Business Unit for the
calendar year is different than the aggregate Computation Period Tax Adjustments
for such Business Unit for such year, such difference shall be added to, or
subtracted from, the next succeeding Computation Period Tax Adjustment for such
Business Unit until fully accounted for.

     (d) The Business Unit Income or Loss and the Computation Period Tax
Adjustments for each Business Unit for each Computation Period shall be
determined by the Company within 20 days following the end of such Computation
Period.

     (e) The Business Unit Income or Loss and the Computation Period Tax
Adjustments for each Business Unit for each taxable year shall be reviewed and
reported on by KPMG Peat Marwick LLP (or other independent certified public
accountants satisfactory to the Representatives) within 90 days following the
end of such taxable year. Such report shall be submitted to the Review Committee
for its approval within 90 days following the end of such taxable year and, once
approved, shall (except for adjustments contemplated by this Section 2.10) be
final, binding and conclusive for purposes of the determinations to be made
pursuant hereto.

     (f) The Company shall furnish to the Representatives all information and
documentation necessary or useful in the computation of each Computation Period
Tax Adjustment and the Tax Adjustment. The Company shall permit the
Representatives, or their designated representatives, to have full access, at
any reasonable time and from time to time during the term of this Agreement and
for a period of five years thereafter, to all relevant tax returns and
supporting papers of the Company Consolidated Group and their Affiliates,
wherever located, and shall furnish, and request that the independent
accountants of the Company Consolidated Group furnish, to the Representatives,
such additional tax and other information and documents in the possession of
such Persons with respect to the Company Consolidated Group and the computation
of each Computation Period Tax Adjustment and the Tax Adjustment as the
Representatives may from time to time reasonably request.

     Section 2.11. Company Loans. The Company may, at its option, make loans and
advances to any Business Unit Entity for the account of any Business Unit from
time to time for the sole purpose of providing working capital and other funds
for use in connection with such Business Unit as contemplated by this Agreement
(each a "Company Loan"); provided, however, that prior to making any Company
Loan, the Company shall pay or cause to be paid in cash any payable owed to such
Business Unit by the Company or any Affiliate of the Company, irrespective of
whether the same are due and payable. To the extent that any Business Unit
requires funds for such purposes, the Company may, at its option, (a) cause the
applicable Business Unit Entity to borrow such funds for the account of such
Business Unit from a financial institution on commercially reasonable terms or
(b) make a Company Loan to such Business Unit Entity for the account of such
Business Unit. The interest rate applicable to each Company Loan shall be no
greater than the interest rate that would be charged to the relevant Business
Unit Entity for a comparable loan made to such Business Unit Entity in an
arms'-length transaction with a Person that is not an Associate of the Company;
provided, however, that if such Business Unit Entity could not reasonably be
expected to obtain such funds through a borrowing from a financial institution
at a per annum interest rate of less than 15%, then such Company Loan shall
accrue interest at the rate of 15% per annum.

     Section 2.12. Advances. In the event that (a) any Business Unit has
insufficient funds for working capital purposes, (b) the Company is not
obligated to make a Revolving Credit Loan to the applicable Business Unit Entity
pursuant to Section 4.03(b), (c) third party financing to fund such working
capital requirements is unavailable to such Business Unit Entity and (d) the
Company elects not to make a Company Loan to such Business Unit Entity for the
account of such Business Unit, such Business Unit Entity or any other Business
Unit Entity may, with the unanimous consent of the Review Committee, loan funds
to such Business Unit from any other Business Unit (each such loan, an
"Advance"); provided, however, that prior to any Advance being made to such
Business Unit, the Company shall pay or cause to be paid in cash any payable
owed to such Business Unit by the Company or any Affiliate of the Company,
irrespective of whether the same are due and payable. Advances shall not bear
any interest and shall be repaid by the recipient Business Unit to the Business
Unit making such Advance on each Calculation Date thereafter, to the extent that
the Excess Cash Flow of such Business Unit as of such Calculation Date exceeds
its working capital requirements after giving effect to any payments required to
be made to the Company pursuant to Section 4.03(c).

     Section 2.13. Underfunding of Employee Benefit Plans. Notwithstanding
anything to the contrary contained in this Agreement, in the event that (a) the
termination of the qualified defined benefit plan currently maintained by THC
results in any costs or benefit payments (other than taxes) paid or to be paid
or incurred by THC or any of its Subsidiaries as the result of such termination
(after all costs that may be paid by such plan are paid by the plan) which are
in excess of the reversion amount (before taxes), if any, of such plan on the
date of its liquidation (the amount of such costs or benefit payments together
with interest accruing thereon at the rate of 5% from the date such costs are
incurred or benefit payments made until the date such benefit costs or payments
are deducted as set forth below being referred to as the "Underfunded Amount")
and (b) the Business Unit Accounts have an aggregate positive balance as of any
Calculation Date ending after the final determination of such Underfunded
Amount, then the aggregate positive balances of the Business Unit Accounts shall
be reduced, prior to

                                       25

<PAGE>

calculating the aggregate number of Contingent Shares to be delivered by the
Company to the Holders pursuant to Section 2.08(b), by an amount equal to the
lesser of (i) the aggregate positive balances of the Business Unit Accounts as
of such Calculation Date and (ii) the amount of such Underfunded Amount which
has not previously been utilized to reduce the aggregate positive balances of
the Business Unit Accounts; provided, however, that in no event shall the
aggregate amount of such reduction to the aggregate positive balances of the
Business Unit Accounts exceed the amount of such Underfunded Amount. The
Representatives shall be entitled to participate in all material decisions
related to the termination of such Pension Plan, including the bidding and
selection of any annuities purchased to fund the obligations of such Pension
Plan, and Rouse shall keep the Representatives fully informed of the status and
details of all actions taken or proposed to be taken in connection therewith.

<PAGE>

     (l) promptly, such other information in the possession of the Company, any
Business Unit Entity or any of their respective Subsidiaries as any member of
the Review Committee may from time to time reasonably request respecting the
Business Units or the Assets comprising any Business Unit.

     Section 4.02. Ownership of Assets of the Business Units. The Company shall
cause the Assets comprising each Business Unit to be maintained at all times in
(a) HHPLP or (b) with the prior written consent of the Representatives, a (i)
separate partnership in which the Company and its Subsidiaries are the only
partners or (ii) direct or indirect wholly-owned Subsidiary of the Company (each
of HHPLP and such partnerships or wholly-owned Subsidiaries being herein called
a "Business Unit Entity"). The Company shall at all times be the direct or
indirect owner of 100% of the Equity Interests of each Business Unit Entity. The
Assets of each Business Unit Entity shall be developed and operated separate and
apart from other Assets now owned or hereafter acquired by the Company or any of
its Subsidiaries or Affiliates and shall be accounted for and administered
hereunder as a single functional unit. The Company shall, as soon as practicable
and in any event within 30 days after the execution and delivery of this
Agreement, amend the Sixth Amended and Restated Agreement of Limited Partnership
of HHPLP, dated as of January 1, 1990, to include provisions which, and the
Company shall cause each other Business Unit Entity to have governing documents
or be a party to Contracts which, (A) implement the provisions of this Article
IV, including provisions which prohibit such Business Unit Entity from taking,
directly or indirectly, any of the actions described in Section 4.05 without the
prior written consent of a majority of the members of the Review Committee, (B)
prohibit such Business Unit Entity from developing commercial buildings on any
of the Assets comprising any Business Unit, (C) prohibit such Business Unit
Entity, without the prior unanimous approval of the Review Committee, from
Transferring any of the Assets comprising any Business Unit other than in
transactions entered into on terms no less favorable than those that could be
obtained in an arm's-length transaction with a Person that is not an Associate
of the Company or any Business Unit Entity and which provide consideration to
the Company or such Business Unit Entity in an amount at least equal to the Fair
Market Value of such Assets and (D) prohibit such Business Unit Entity from
amending, modifying or supplementing its governing documents or such Contracts
in any manner which affects the provisions described in clauses (A) through (C)
above or this clause (D). The Company shall, to the extent reasonably
practicable, consult with the Review Committee before initiating or responding
to any material Claim affecting any Business Unit or any of the Assets
comprising such Business Unit. The Representatives may, by an instrument in
writing, waive compliance by the Company with any provision of this Section
4.02, either generally or in a particular instance and either retroactively or
prospectively.

     Section 4.03. Capitalization of Business Units. (a) With respect to the
Playa Vista Business Unit, capital requirements shall be as determined under the
Playa Vista Partnership Agreements. At the present time, capital requirements
are mutually determined by Maguire Thomas Partners and by HHPLP or its
Affiliates. However, such requirements are currently under review in connection
with the restructuring of the Playa Vista Partnership Agreements to permit
participation by Dreamworks SKG and the related equity and debt financings which
are contemplated in connection with such restructuring (the "Playa Vista
Financings"). To the extent that HHPLP (which term includes for purposes of the
remaining provisions of this paragraph (a) any Business Unit Entity succeeding
to the interests of HHPLP in the Assets comprising the Playa Vista Business
Unit) or its Affiliates, together with Maguire Thomas Partners, determine to
contribute additional capital to either of the Playa Vista Partnerships
(including any contributions in connection with the Dreamworks SKG
restructuring), the Company shall make such contributions to the Playa Vista
Partnerships on behalf of HHPLP or its Affiliates in an amount not to exceed
$15,000,000 (the "Funding Requirement"); provided, however, that the Company
shall not be obligated to make any such contribution unless (i) with respect to
all or any portion of the first $10,000,000 of the Funding Requirement, a
majority of the members of the Review Committee determine that the Company
should make such contribution at such time and (ii) with respect to all or any
portion of the Funding Requirement in excess of $10,000,000, all of the members
of the Review Committee determine that the Company should make such contribution
at such time and, provided further, that any capital contributions made to the
Playa Vista Partnerships during the period commencing January 1, 1996 to and
including the Effective Time shall be deemed for all purposes of this Agreement
to have been made by the Company pursuant to the Funding Requirement. If funding
is provided by the Company pursuant to the Funding Requirement, the Holders
shall be entitled to the benefit of the Hughes Funding pursuant to the Value
Indices with respect to the Playa Vista Business Unit. If the Company funds less
than $10,000,000 pursuant to the Funding Requirement, the Company shall, on or
before the tenth day after the Termination Date, credit the Playa Vista Business
Unit Account with an amount equal to (A) $10,000,000 minus the amount of the
Hughes Funding plus (B) a 7% per annum, compounded semi-annually, return on such
amount

                                       30

<PAGE>

accruing from the effective date hereof until such amount is credited to the
Playa Vista Business Unit Account. To the extent that all or any portion of the
Funding Requirement is not funded nor required to be funded pursuant to this
paragraph (a) and is not credited nor required to be credited to the Playa Vista
Business Unit Account pursuant to the immediately preceding sentence, the
obligation of the Company to fund such amount shall expire at such time as the
Playa Vista Financings are consummated or, if not consummated, at such time as
the agreements between HHPLP or its Affiliates and Maguire Thomas Partners for
mutually agreed commitments to capital for the project expire or are terminated
(the "Termination Date").

     (b) Subject to the terms and conditions hereof, during the period
commencing on the Effective Date and continuing thereafter to and until the date
which is nine months after the Effective Date, the Company shall, from time to
time, make a loan or loans to the Business Unit Entities owning the Assets
comprising the General Business Unit, the Howard Hughes Center Business Unit and
the Summerlin Business Unit, on a revolving credit basis, in an aggregate
principal amount not at any time exceeding $25,000,000 (the "Revolving Credit
Loans"); provided, however, that if, on the date which is nine months after the
Effective Date, the unutilized portion of the commitment under the working
capital component of the Bank of America credit facility currently available to
HHPLP, or any replacement facility, is less than $20,000,000, then the Company
shall continue to, from time to time, make Revolving Credit Loans to such
Business Unit Entities until the date which is two years after the Effective
Date, in an aggregate principal amount not at any time exceeding $20,000,000
minus the unutilized portion of such commitment on the date which is nine months
after the Effective Date. Each Revolving Credit Loan made by the Company to a
Business Unit Entity shall be made solely for the account of a single Business
Unit. In no event will the Company be obligated to make any Revolving Credit
Loan to any Business Unit Entity unless such Business Unit Entity could not
reasonably be expected to obtain funds for the working capital requirements of
the applicable Business Unit through a borrowing from a financial institution on
commercially reasonable terms. The proceeds of each Revolving Credit Loan shall
be used by the Business Unit Entity borrowing such funds solely (i) for working
capital purposes of the relevant Business Unit for whose account such Revolving
Credit Loan was made and (ii) in connection with the operation of the relevant
Business Unit for whose account such Revolving Credit Loan was made and the
Assets comprising such Business Unit. The terms and conditions of each Revolving
Credit Loan shall be no less favorable to the borrowing Business Unit Entity
than would be obtained in an arms'-length transaction with a Person that is not
an Associate, except that each Revolving Credit Loan shall bear interest on the
unpaid principal amount thereof from the date such Revolving Credit Loan is made
until repaid at a floating rate per annum equal to the prime rate of interest
charged from time to time by the First National Bank of Maryland. In the event
that the aggregate working capital requirements of two or more of the Business
Units referred to above exceed $25,000,000 at any time, the Revolving Credit
Loans required hereby may be allocated by the Company between or among such
Business Units as it reasonably determines in good faith. The Revolving Credit
Loans will not be deemed to be Company Loans and vice versa.

     (c) On each Calculation Date occurring while any amount under any Revolving
Credit Loan remains outstanding, the working capital needs of the General
Business Unit, the Howard Hughes Business Unit and the Summerlin Business Unit
shall be reviewed. To the extent that Excess Cash Flow for the applicable
Computation Period for any such Business Unit exceeds the funds required by such
Business Unit for working capital purposes, such excess shall be paid by the
applicable Business Unit Entity towards the repayment of any Revolving Credit
Loans made by the Company to such Business Unit Entity for the account of such
Business Unit. To the extent that any amount under any Revolving Credit Loan
remains outstanding after giving effect to the payments contemplated by the
immediately preceding sentence, any amounts held by the applicable Business Unit
Entities for the account of any Business Unit in excess of the funds required by
such Business Unit for working capital purposes shall be paid to the Company by
such Business Unit Entities, pro rata based upon the amounts of such excess
funds, towards the repayment of any Revolving Credit Loans made by the Company
to any Business Unit Entity for the account of any other Business Unit. Any
amount paid by a Business Unit Entity for the account of a Business Unit towards
the payment of a Revolving Credit Loan made to a Business Unit Entity for the
account of any other Business Unit shall constitute (i) an Advance by the
Business Unit for whose account such payment is being made to the Business Unit
for whose account such Revolving Credit Loan was borrowed and (ii) a payment
from the Business Unit for whose account such Revolving Credit Loan was borrowed
to the Company. Any payments made by any Business Unit Entity to the Company
pursuant to this paragraph (c) shall be applied first to interest, then to
principal.

          in an arm's- length transaction with a Person that is not an Associate
          of the Company or any Business Unit Entity, or (B) could reasonably be
          expected to result in a material adverse effect on (1) the Company's

          and the Summerlin Business Unit;

     (c) Notwithstanding the foregoing, no transaction described in clauses
(a)(i) through (a)(iv) above or clauses (b)(ii) through (b)(iv) above shall
require the consent of the Review Committee if and to the extent that such
transaction has been duly approved by the Board of Directors of THC prior to the

or other modification shall have been duly approved by the holders of the
Contingent Preferred Shares or the Representatives in accordance with the
provisions of the Rouse Increasing Rate Preferred Stock or (ii) in the event
that no Contingent Preferred Shares are issued and outstanding, the Company
shall have obtained the approval of its shareholders contemplated by Section

described in clause (ii) have been satisfied, the Company may, without the
consent of any Holder or the Representatives, amend such Articles to eliminate
the restrictions contained

                                       33

Agreement, the Representatives will be entitled to designate an individual for
election to the Rouse Board; provided, however, that such individual is
reasonably acceptable to the Company at the time of his initial designation.
Pursuant to the terms of the Merger Agreement, the Company, in accordance with
its bylaws, has increased the size of the Rouse Board by one and caused the
vacancy created by such increase to be filled by the election of the individual
designated on behalf of the Holders in the Merger Agreement (the "Holders'
Designee"), which election is effective as of the Effective Date. Such Holders'
Designee will serve until the first annual meeting of the stockholders of the
Company following the date hereof and until his successor shall be duly elected
and qualified or until his death, disability, removal or resignation.

     (b) So long as the Representatives possess the right of designation
described in paragraph (a) above, the Company shall nominate (or shall cause to
be nominated) for election at each annual meeting of the stockholders of the
Company after the date hereof, the incumbent Holders' Designee or such other
individual as the Representatives may designate; provided, however, that such
other individual is reasonably acceptable to the Company at the time of his
initial designation.

     (c) So long as the Representatives possess the right of designation
described in paragraph (a) above, if the Holders' Designee should die, become
disabled, be removed, retire or resign during the term of his office, the
Representatives shall be entitled to designate a successor Holders' Designee
reasonably acceptable to the Company at the time of his initial designation, in
which event the Company shall cause such successor Holders' Designee to be
promptly elected as a member of the Rouse Board to fill the vacancy created by
such death, disability, removal, retirement or resignation.

     (d) So long as the Representatives possess the right of designation
described in paragraph (a) above, without the prior written consent of the
Representatives (which consent will not be unreasonably withheld), neither the
Company nor the Rouse Board will (i) recommend that the Holders' Designee be
removed by the stockholders of the Company or (ii) fail to recommend any
incumbent Holders' Designee for reelection.

     Section 4.07. Treasury Shares. All purchases or other acquisitions of
shares of Rouse Common Stock by the Company shall be implemented in compliance

and accounts of the Company and any Business Unit Entity), all at such
reasonable times and as often as such Review Committee member or such
Representative may reasonably request. As an accommodation to the Company, the
Representatives will endeavor to arrange their visits and inspections hereunder
to coincide with the regular meetings of the Review Committee contemplated by
Section 6.01; provided, however, that the Representatives shall not be so
obligated if they believe the Company may not be in compliance with any
provision of this Agreement. All out-of-pocket expenses incurred by the Company,
the Holder Members and the Independent Member in connection with such visits and
inspections shall constitute Expenditures hereunder; provided, however, that (i)
in no event shall any other cost or expense, including any salary or other
wages, incurred

                                       34

between any member of the Review Committee and any officers, directors or
employees of the Company or any Business Unit Entity be deemed an Expenditure
hereunder and (ii) if an Event of Default shall have occurred and be continuing,

deemed an Expenditure hereunder.

the Holders and record therein each Holder's name, address and Percentage
Interest. Such registry shall be kept at the principal corporate office of the
Company and shall be made available for inspection by any Representative or any

shall initially be comprised of the Persons and other information set forth on

Assignee, such notice specifying the name of the Transferring Holder, the name
and address for notice purposes of such Eligible Assignee, the Percentage
Interest Transferred to such Eligible Assignee and the cause (if applicable) of
the Transfer, the Company shall revise the registry to reflect such Transfer.
The Company, the Representatives and the Escrow Agent may deem and treat the
Persons listed in the registry as the Holders for all purposes of this
Agreement. Any request, authority or consent of any Person who, at the time of
making of such request or giving such authority or consent, is a Holder shall be
conclusive and binding on any subsequent Eligible Assignee of such Holder.

customarily obtained by the Company in connection with its own Assets and
operations.

     Section 4.13. Corporate Existence; Etc. Subject to the provisions of

Stock Exchange require such approval prior to the Company issuing new shares of
Rouse Common Stock for delivery to the Holders in satisfaction of its obligation

limitation of the foregoing, if and to the extent so required, prior to July 1,
1997 the Company shall (i) submit this Agreement and the transactions
contemplated hereby for the approval of its shareholders at a meeting of its
shareholders to be held prior to July 15, 1997, (ii) through the Rouse Board,
recommend to its shareholders approval of this Agreement and the transactions

shall be a remedy properly available to the Representatives and the Holders for
a breach of such covenant.

     Section 4.16. Contingent Preferred Shares. Notwithstanding any provision of
this Agreement to the contrary, if the Company is required to deliver Contingent

Contingent Shares on the Delivery Date, including any such preclusion or
inability which results because the issuance by the

                                       36

<PAGE>

Company of shares of Rouse Common Stock and delivery of such shares to the
Holders in satisfaction of its obligation to deliver Contingent Shares hereunder
would be a breach or violation of any then effective New York Stock Exchange
Listing Agreement to which the Company is a party, then the Company shall
immediately issue and deliver shares of Rouse Increasing Rate Preferred Stock
("Contingent Preferred Shares") in lieu thereof. The aggregate number of
Contingent Preferred Shares (including fractional shares) to be issued and
delivered by the Company on any Delivery Date shall be determined by dividing
(a) 125% of the sum of (i) the aggregate number of Contingent Shares originally
required to be delivered by the Company on the Delivery Date plus (ii) the
aggregate number of Contingent Shares required to be delivered by the Company
pursuant to Section 2.08(d) by (b) the quotient of (i) $100 divided by (ii) the
Current Share Value used in calculating such aggregate number of such Contingent
Shares. The obligation of the Company to issue and deliver shares of Contingent
Preferred Shares under this Section 4.16 shall terminate if and when this
Agreement and the transactions contemplated hereby have been duly and validly
approved by the Company's shareholders as contemplated by Section 4.15;
provided, however, that no such termination shall relieve the Company from (A)
any liability for any breach of this Section 4.16 prior to such termination or
(B) any obligation to deliver Contingent Preferred Shares pursuant to Section
2.08(e).

     Section 4.17. Reservation of Shares. (a) The Company will at all times
reserve and keep available (free of preemptive rights), out of its authorized
and unissued shares of Rouse Common Stock solely for issuance pursuant to this
Agreement, the full number of shares of Rouse Common Stock as the Rouse Board,
after consultation with independent financial advisors and legal counsel, shall
determine in good faith to be issuable under this Agreement.

     (b) The Company will at all times reserve and keep available (free of
preemptive rights), solely for issuance pursuant to this Agreement, all shares
of Rouse Preferred Stock constituting the Rouse Increasing Rate Preferred Stock.

     Section 4.18. Abandonment of Assets. In the event that: (a) the Company, in
its good faith judgment, determines, based upon reasonable assumptions and after
consultation with the Review Committee, that the continued ownership and
operation of any Business Unit would be neither profitable to nor in the best
interests of the Company and the Holders; (b) the Company is not obligated to
make a Revolving Credit Loan to the applicable Business Unit Entity pursuant to
Section 4.03(b); (c) third party financing to fund the cash requirements of such
Business Unit is unavailable to the applicable Business Unit Entity; (d) the
Company is unwilling to make a Company Loan to the applicable Business Unit
Entity in connection with such Business Unit; and (e) the Review Committee has
rejected a request to have another Business Unit make an Advance to such
Business Unit, then the Company may cease to operate such Business Unit;
provided, however, that prior to any such cessation, the Company shall (i)
unless otherwise consented to by the Representatives, use commercially
reasonable efforts for a period of at least 12 months to market and sell or
lease the Assets comprising such Business Unit and (ii) if no potential
purchaser or lessee for any of such Assets exists as of the last day of such
period, the Company shall, unless otherwise consented to by the Representatives,
sell any such Assets at a public auction, for cash or credit, at the highest
price bid for such Assets at such auction. Any and all costs, expenses and
proceeds that are incurred, paid and received, as applicable, in connection with
any such sale of Assets shall constitute Receipts and Expenditures, as
applicable, with respect to the applicable Business Unit and, provided further,
that in the event that such cessation relates to the Playa Vista Business Unit
prior to the Termination Date, and the Company has funded less than $10,000,000
pursuant to the Funding Requirement, the Company shall, on the date of such
cessation, credit the Playa Vista Business Unit Account with an amount equal to:
(i) $10,000,000 minus the amount of the Hughes Funding plus (ii) a 7% per annum,
compounded semi-annually, return on such amount accruing from the effective date
hereof until such amount is credited to the Playa Vista Business Unit Account.

     Section 5.01. Authority and Liabilities of the Representatives. (a) Except
as otherwise provided herein, (i) the Representatives shall have full power and
authority to represent the Holders with respect to all matters arising under
this Agreement and shall have, and may exercise, such rights, powers, privileges
and remedies as are reasonably incidental thereto and (ii) all actions taken by
the Representatives hereunder shall be binding upon the Holders, as if expressly
confirmed and ratified by each of the Holders. Without limiting the

                                       37

<PAGE>

generality of the foregoing, except as otherwise provided herein, the
Representatives shall have full power and authority, on behalf of the Holders,
to interpret all of the terms and provisions of this Agreement and to compromise
and settle all disputes between the Company and the Holders (or any of them)
arising under this Agreement. So long as the Representatives are authorized to
act under this Agreement, each of the Holders hereby irrevocably appoints the
Representatives to act as the attorney-in-fact of such Holder, with full
authority in its place and stead, and in the name of the Holders, the
Representatives or otherwise, from time to time to take any action and to
execute any instrument which the Representatives may deem necessary or advisable
to carry out their duties and responsibilities and otherwise act under this
Agreement.

     (b) The Representatives will be acting herein solely as an accommodation to
the Holders, and each Representative, in exercising his rights, powers,
privileges and remedies and performing his duties and responsibilities
hereunder, will endeavor to use the same care that he uses when acting solely
for his own account. The duties of the Representatives shall be determined only
with reference to this Agreement, and no Representative is or shall be charged
with knowledge of, or with any duties or responsibilities under or in connection
with, any other document or instrument. No implied duties or covenants shall be
read into this Agreement on the part of the Representatives. No Representative
shall be obligated to take any legal action hereunder which is contrary to
applicable Law or which might, in such Representative's judgment, involve any
expense or Liability unless such Representative has been indemnified to his
satisfaction by the Holders. The Representatives shall be authorized to exercise
their discretion in acting or refraining from acting hereunder and in connection
herewith and shall not be liable for any mistakes of fact or errors of judgment,
or for any acts or omissions of any kind, unless caused by the willful
misconduct or gross negligence of such Representative. IT IS THE INTENT OF THE
PARTIES THAT NO REPRESENTATIVE SHALL BE LIABLE FOR OR ON ACCOUNT OF ANY ACTION
TAKEN OR OMITTED BY HIM HEREUNDER OR IN CONNECTION HEREWITH CAUSED BY THE
ORDINARY NEGLIGENCE (WHETHER SOLE OR CONTRIBUTORY) OF SUCH REPRESENTATIVE. In no
event shall any Representative be liable to any Person for incidental,
consequential or indirect damages in his capacity as such. Except as provided in
Sections 5.01(e) and 5.11, no Representative shall have any duty to the Company,
any of its Subsidiaries or the Review Committee, nor shall any Representative be
liable to the Company or any of its officers, directors, shareholders, partners,
employees, agents, servants or Subsidiaries or any member of the Review
Committee for any act or failure to act hereunder or connection herewith.

     (c) No Representative shall be under any obligation to make any
investigation in respect of the subject matter of this Agreement. No
Representative shall be charged with knowledge (actual or constructive) of any
Event of Default or any failure on the part of the Company in the performance of
its obligations hereunder, unless a clear written notice thereof shall have been
previously furnished to such Representative.

     (d) Each individual serving as a Representative hereunder will be acting
only in his capacity as a Representative and not in his individual capacity or
in any other capacity, including as an agent, representative, employee, officer,
director, stockholder, partner or fiduciary of any other Person. Accordingly,
notwithstanding anything contained herein or elsewhere to the contrary, in no
event shall any Associate of any Representative be liable for or on account of
any action taken or omitted by such Representative nor shall recourse be had to
the Assets or business of any such Associate on account of any such action or
omission.

     (e) Any Representative may be or become a Holder and may otherwise deal
with the Company and its Subsidiaries with the same rights he would have if he
were not a Representative hereunder. Without limitation of the foregoing, any
Representative who is also a Holder shall have, and may exercise, all the rights
and powers vested in such Representative in his capacity as a Holder the same as
if such Representative were not a Representative hereunder.

     (f) No Representative shall hold himself out to be an agent, employee or
representative of the Company, and no act or omission by any Representative
shall bind or obligate the Company, any of its Subsidiaries or any Business Unit
Entity.

     Section 5.02. Directions to Representatives. (a) The Representatives may
rely upon and shall in all respects be fully protected in acting or refraining
from acting in accordance with any request, instruction or direction of the
Majority Holders, and the Representatives shall not be liable for any action
taken, suffered or omitted by them in accordance with any such request,
instruction or direction. Each request, instruction or direction

                                       38

<PAGE>

made or given to the Representatives by the Majority Holders, and any action
taken, suffered or omitted by the Representatives pursuant thereto, shall be
binding upon all Holders. No Representative shall be under any obligation to
take any action or refrain from taking action at the request, instruction or
direction of the Holders (or any of them).

     (b) The Representatives may at any time request instructions from the
Majority Holders with respect to any matter arising hereunder or in connection
herewith, and the Representatives (i) shall be entitled to refrain from acting
with respect to such matter unless and until they have received instructions
from the Majority Holders to do so and (ii) shall not incur Liability to any
Person by reason of so refraining.

     Section 5.03. Reliance Upon Documents and Opinions of Counsel. Each
Representative may rely and shall be fully protected in acting upon any notice,
request, consent, certificate, resolution, appraisal, report or other paper or
document believed by him to be genuine and to have signed or presented by the
proper Person or Persons. Each Representative may consult with counsel (who may
be of counsel to the Company) and the opinion of such counsel shall be full and
complete authorization and protection in respect of any action taken or suffered
by such Representative hereunder in good faith and in accordance with the
opinion of such counsel.

     Section 5.04. No Responsibility for Recitals, Etc. The recitals and
statements contained in this Agreement shall be taken as the recitals and
statements of the Company only, and no Representative assumes responsibility for
the correctness of the same. No Representative shall be liable or responsible to
any Person for (i) the representations, warranties or other statements made by
any other Person, (ii) the performance of this Agreement or any other instrument
or document by the Company or any of its Subsidiaries, (iii) any actions taken
or omitted by any other Person or (iv) the execution, value, sufficiency,
validity or enforceability of this Agreement or any other instrument or
document. No Representative shall be accountable to any Holder for any shares of
Rouse Common Stock or Rouse Increasing Rate Preferred Stock delivered hereunder
or responsible for the business, operations, Assets, condition (financial or
other) or results of operation of the Company or any of its Subsidiaries.

     Section 5.05. Actions by Representatives. (a) Except as otherwise expressly
provided herein, all actions required or permitted to be taken by the
Representatives hereunder shall be evidenced by, and taken upon, the written
direction of a majority of the Representatives. The Company shall be entitled to
rely on the representations of a majority of the Representatives as to their
authority to take any action under or in connection with this Agreement.

     (b) The Representatives may exercise any of their rights, power, privileges
or remedies hereunder or perform any of their duties hereunder either directly
or by or through agents or attorneys, and no Representative shall be responsible
for any misconduct or negligence on the part of any agent or attorneys appointed
by the Representatives with due care hereunder. The Representatives shall be
entitled to retain and consult with such independent advisors and other experts
as the Representatives shall deem necessary or appropriate in connection with
the performance of their duties and responsibilities and the exercise of their
authority or powers hereunder.

     Section 5.06. Resignation and Removal. (a) Any Representative may at any
time resign and be discharged of his duties and obligations hereunder by giving
not less than 30 days' prior written notice to the Company, the other
Representatives and the Holders. Such resignation shall take place on the day
specified in such notice, unless previously a successor Representative shall
have been appointed as provided in Section 5.07, in which event such resignation
shall take effect immediately upon the appointment of such successor
Representative.

     (b) Any Representative may be removed at any time, with or without cause,
by an instrument or instruments in writing signed by the Majority Holders,
specifying the removal and the date when it shall take effect. Upon the
resignation or removal of any Representative becoming effective, all the rights,
powers, duties and obligations of such Representative shall forthwith terminate
except as otherwise provided herein.

     (c) Subject to the provisions of Sections 5.01, 5.02, 5.03, 5.04 and 5.05,
no such resignation or removal shall relieve any Representative from Liability
for any breach of this Agreement by such Representative prior to the effective
date of such resignation or removal. Anything herein to the contrary
notwithstanding, all

                                       39

<PAGE>

indemnities and rights to payment and reimbursement of each Representative
hereunder shall survive his resignation or removal and the Company's performance
of its obligations hereunder.

     Section 5.07. Appointment of Successor Representative. (a) In the event of
the death, resignation or incapacity of any Representative, the remaining
Representatives (whether one or more) shall appoint a successor Representative
by an instrument or instruments in writing executed by the remaining
Representatives and delivered to the Company and the Holders; provided, however,
that if no appointment of a successor Representative shall have been made within
30 days after the date of such death, resignation or incapacity, as the case may
be, the Majority Holders shall have the right to appoint a successor
Representative by written notice given to the Company and the remaining
Representatives. For purposes of this paragraph (a), "incapacity" means, when
respect to any Representative, a physical or mental condition which, in the good
faith judgment of the other Representatives, (i) prevents such Representative
from being able to perform the services contemplated to be performed by a
Representative under this Agreement, (ii) has continued for at least 90 days and
(iii) is expected to continue.

     (b) In the event a Representative shall be removed by the Majority Holders
as provided in Section 5.06(b), the Majority Holders may appoint a successor
Representative by an instrument or instruments in writing signed by the Majority
Holders and delivered to the Company and the remaining Representatives. In the
event the Majority Holders fail to so appoint a successor Representative within
30 days after the date of such removal, the remaining Representatives (whether
one or more) shall have the right to appoint a successor Representative by an
instrument or instruments in writing executed by the remaining Representatives
and delivered to the Company and the Holders.

     (c) If any Representative shall die or resign or be removed in accordance
with Section 5.06 and if a successor Representative shall not have been
appointed within 60 days after the day of such death, resignation or removal,
either of the remaining Representatives may apply to any court of competent
jurisdiction to appoint a successor Representative, and such court may
thereupon, after such notice (if any) as it may consider proper, appoint a
successor Representative.

     Section 5.08. Acceptance of Appointment by Successor Representative. Any
successor Representative appointed hereunder shall execute and deliver to the
remaining Representatives (for the express benefit of all the Holders) an
instrument in writing accepting such appointment (a copy of which shall be sent
to all Holders), and thereupon such successor Representative, without further
act or deed, shall become vested with all the rights, powers, duties and
obligations of his predecessor, with like effect as if originally named as a
Representative herein.

     Section 5.09. Compensation and Indemnification. (a) The Representatives
shall look solely to the Holders and the Escrow Account for payment of any
compensation payable to them for their services hereunder and for any
indemnification against any Liability incurred by them in connection with the
Agreement. As compensation for performance of services hereunder as
Representatives, each Representative shall receive an amount equal to $30,000
(subject to adjustment as provided below) per annum, payable monthly in arrears
on the last day of each calendar month for so long as such Representative has
any duties or obligations under this Agreement, plus such additional
compensation as may at any time or from time to time be proposed in writing by
the Representatives (or any one of them) and approved by the Majority Holders.
In the event this Agreement, or the period of service hereunder of any
Representative, shall commence or end on other than the first or last day of a
calendar month, such monthly amount (but no other amount unless otherwise
agreed) shall be appropriately prorated. All payments due to the Representatives
under the foregoing sentence may be paid from the Escrow Account and the
Representatives shall be authorized to make withdrawals from the Escrow Account
for such purpose. The amount of the annual fee referred to above shall be
adjusted upwards or downwards, as the case may be, for each calendar year
commencing after the date hereof by the amount of the change (if any) in the
Cost of Living during the prior calendar year based on the Consumer Price Index
for Urban Consumers All Items--Less Shelter--Index (1967=100) as published with
respect to the greater Houston metropolitan area by the Bureau of Labor
Statistics for the United States Department of Labor. If such Index is
discontinued or revised in any material respect, the Representatives, acting in
good faith and after consultation with an independent consultant, shall
designate a substitute index which shall thereafter be used in order to obtain
substantially the same result as would have been obtained had such Index not
been so discontinued or revised.

                                       40

<PAGE>

     (b) In addition to the fees described above, each Representative shall be
entitled to be promptly reimbursed by the Holders for the reasonable
out-of-pocket expenses incurred by such Representative in connection with his
service as a Representative hereunder. All payments due to the Representatives
under the foregoing sentence may be paid from the Escrow Account and the
Representatives shall be authorized to make withdrawals from the Escrow Account
for such purpose.

     Section 5.10. Representatives' Escrow Account. (a) Contemporaneously with
the execution of this Agreement, the Representatives shall establish a special
purpose escrow account with a bank or trust company selected by the
Representatives (the "Escrow Agent"). The Escrow Agent shall administer the
Escrow Account in accordance with the terms and conditions of an escrow
agreement to be entered into between the Representatives and the Escrow Agent
(the "Escrow Agreement"). The Escrow Agreement shall be in such form and contain
such terms and conditions (consistent with this Agreement) as the
Representatives shall approve. The Escrow Account shall be held by and remain in
the exclusive possession of, and under the sole dominion and control of, the
Representatives for the ratable benefit of the Holders and the Representatives
during the period from the date hereof until the date on which the
Representatives shall cease to have any further duties or obligations hereunder
(the "Escrow Termination Date") and shall be maintained at all times in
accordance with the terms of this Agreement. Unless otherwise specifically
provided herein, the Escrow Account shall be subject to debit or withdrawals
solely by the Representatives as provided in this Agreement and no other Person
shall have any control over or right of withdrawal from the Escrow Account;
provided, however, that if at any time there shall not be any Representative
then serving hereunder, disbursements from the Escrow Account may be authorized
upon written instructions from the Majority Holders. No payments shall be made
out of the Escrow Account except for the purposes and on the terms provided in
this Agreement. As security for all compensation, expenses, indemnification
payments and other amounts due or to become due to the Representative hereunder,
each Representative, without any action on the part of the Holders, the Escrow
Agent or any other Person, shall have and may enforce a first priority security
interest in and Lien upon all moneys and other Assets contained from time to
time in the Escrow Account.

     (b) Concurrently with the execution of this Agreement, there is being
transferred to the Escrow Account the sum of $1,500,000 pursuant to
authorization set forth in that certain Agreement and Plan of Merger dated as of
February 22, 1996 among the Company, TRC Acquisition Company II, a Delaware
corporation, and HHPLP relating to the Partnership Merger. If, subsequent to the
date hereof, the Representatives acting in good faith believe that additional
funds are required or may be required for the Escrow Account in order to enable
the Representatives to receive the compensation to which they are entitled
hereunder and to discharge their responsibilities and duties and otherwise act
on behalf of Holders pursuant to this Agreement, the Representatives shall have
the right to direct that a specified number of the Contingent Shares and/or
Contingent Preferred Shares otherwise issuable to the Holders hereunder,
determined as of the next succeeding Calculation Date, be withheld and instead
delivered to or as directed by the Representatives, such Contingent Shares
and/or Contingent Preferred Shares to be withheld from the Contingent Shares
and/or Contingent Preferred Shares otherwise deliverable to the Holders pro rata
in accordance with their respective Percentage Interests. Such direction shall
be evidenced by notice duly authorized and given by the Representatives to the
Company (a "Representatives' Diversion Notice"), a copy of which shall be
concurrently mailed to all Holders, in which event the Company shall be
obligated to withhold and so direct and deliver the Contingent Shares and/or
Contingent Preferred Shares as provided in the Representatives' Diversion
Notice. The Representatives shall cause the Contingent Shares and/or Contingent
Preferred Shares so received to be sold as promptly as prudent marketing
conditions will permit with the net proceeds of each such sale to be deposited
to the Escrow Account. Any and all deposits made into the Escrow Account shall
be irrevocable and the amount of such deposit and any interest and investment
earnings thereon shall be held by the Representatives and applied, invested and
transferred solely as provided herein and in the Escrow Agreement.

     (c) Anything in this Section 5.10 to the contrary notwithstanding, the
Majority Holders may at any time or from time to time by written notice to the
Representatives (i) instruct the Representatives to withdraw any
Representatives' Diversion Notice or (ii) authorize or direct that all or part
of any amounts deposited in the Escrow Account in accordance with paragraph (b)
above be distributed to all Holders ratably in accordance with their respective
Percentage Interests.

                                       41

<PAGE>

     (d) The Representatives shall maintain or cause to be maintained at the
expense of the Holders, books of account on a cash basis and record therein (i)
all funds received by the Representatives on behalf of the Holders, (ii) all
payments or disbursements of funds to the Representatives in payment of
compensation or for reimbursement of expenses pursuant to Section 5.09, (iii)
all payments or disbursements to any other Person for the benefit of, or
approved by, the Holders, (iv) all other deposits into and transfers to and from
the Escrow Account and (v) all investment transactions contemplated by paragraph
(f) below effected by the Representatives and/or the Escrow Agent. The
Representatives shall endeavor to make such books of account available during
normal business hours for inspection by the Holders and their respective
representatives upon reasonable prior notice, but only if the Holders or Holders
requesting such inspection agree to pay all costs and expenses relating thereto.
In addition to such books of account, the Representatives shall maintain or
cause to be maintained at all times a current list of the investments in the
Escrow Account. Not later than the 60th day after each Calculation Date, the
Representatives shall provide or cause to be provided to the Holders a statement
specifying the amounts held in, and the activity for, the Escrow Account at the
close of business on the last business day preceding such Calculation Date.

     (e) The Representatives shall transfer funds available in the Escrow
Account as follows:

               (i) at any time and from time to time, the Representatives shall
          withdraw amounts held in the Escrow Account and apply such amounts as
          required or permitted by this Agreement; and

               (ii) on the Escrow Termination Date, the Representatives shall
          withdraw any and all amounts held in the Escrow Account from the
          Escrow Account and, after the payment or provision for payment of all
          expenses and Liabilities of the Holders and the Representatives under
          this Agreement, transfer the remaining amount to the Holders ratably
          in accordance with their respective Percentage Interests.

In addition, the Representatives may at any time or from time to time withdraw
all or part of the funds in the Escrow Account and distribute the funds so
withdrawn to the Holders ratably in accordance with their respective Percentage
Interests.

     (f) Amounts held in the Escrow Account shall be invested only in Permitted
Investments. Any interest, investment income or gain realized as a result of any
of the amounts held in the Escrow Account (net of the expenses incurred in
connection with making any Permitted Investments) shall be credited to the
Escrow Account and may be reinvested in Permitted Investments. Neither the
Escrow Agent nor any of the Representatives (or their Associates) shall have any
liability to any of the Holders or any other Person for any Loss resulting from
any Permitted Investment other than Losses arising out of his or its willful
misconduct, fraud or gross negligence. For purposes of this Agreement, the term
"Permitted Investments" means any of the following investments: (i) securities
issued or directly and fully guaranteed or insured by the United States or any
agency or instrumentality thereof (provided that the full faith and credit of
the United States is pledged in support thereof) having a maturity not exceeding
30 days from the date of acquisition, (ii) time deposits and certificates of
deposit of any commercial bank of recognized standing having capital and surplus
in excess of $500,000,000, provided that the long term senior unsecured debt of
such bank is rated at least A+ or the equivalent thereof by Standard & Poor's
Corporation or at least A1 or the equivalent thereof by Moody's Investors
Service, having a maturity not exceeding 30 days from the date of acquisition,
and (iii) commercial paper issued by the parent corporation of any commercial
bank or by any domestic corporation, provided that such commercial paper is
rated at least A-1 or the equivalent thereof by Standard & Poor's Corporation or
at least P-1 or the equivalent thereof by Moody's Investors Service, having a
maturity not exceeding 30 days from the date of acquisition.

     (g) Any and all interest and other income earned or loss realized on any
Contingent Shares or Preferred Contingent Shares held by the Representatives for
the benefit of the Holders or any amounts held in the Escrow Account for any and
all federal, state and local income tax purposes shall be attributed to the
Holders. The Representatives shall provide, or cause to be provided, information
to the Holders to enable the Holders to (i) determine any and all requirements
of governmental authorities for the payment of taxes and the reporting or
withholding of any payments for tax purposes hereunder and (ii) prepare and
file, or cause to be prepared and filed, all tax returns, reports and other
information required with respect to the Escrow Account. The Holders, ratably
according to their respective Percentage Interests, shall indemnify and hold the
Representatives harmless against any and all Claims, Liabilities and Losses for
tax withholding and/or reporting for any payments made hereunder. Such
indemnities shall survive the Escrow Termination Date, the termination or
discharge of this Agreement and the

                                       42

<PAGE>

death, resignation or removal of any Representative. The Representatives shall
have no obligation whatsoever with respect to the making, reporting or
withholding of any payments for tax purposes. If requested by the
Representatives, each Holder will provide the Representatives with such
information as may be required by applicable taxing authorities or tax Laws.

     Section 5.11. Confidentiality. No Representative will disclose to any
Person, or use for any improper purpose, any of documents or other information
furnished to it by the Company hereunder except for the purposes contemplated by
this Agreement. Notwithstanding the foregoing, each Representative shall be
permitted to:

     (a) disclose any such documents or other information (i) to the Company or
any employee, agent, advisor, consultant, officer, director or stockholder of
the Company or any Affiliate of the Company, (ii) to any member of the Review
Committee or any employee, agent, legal counsel, accountant, advisor or
consultant of the Review Committee or (iii) to the extent that such documents or
information (A) are furnished or made available to such Representative by the
Company on a non-confidential basis, (B) is or becomes generally known or
available other than as a result of a disclosure by such Representative or (C)
is or becomes known or available to such Representative on a non-confidential
basis from a source (other than the Company) which, to such Representative's
knowledge, is not prohibited from disclosing such documents or information to
such Representative by a legal, contractual, fiduciary or other obligation to
the Company; and

     (b) otherwise disclose and use any such documents or other information (i)
as the Company shall approve from time to time (which approval shall not be
unreasonably withheld), (ii) as shall be required in response to any summons or
subpoena or in connection with any litigation, (iii) to the extent such
Representative believes it necessary to comply with applicable Law or (iv) to
the extent such Representative believes it necessary in the performance of his
duties and obligations hereunder or in the exercise or enforcement of his
rights, powers, privileges, remedies or immunities hereunder.

     If any Representative intends to disclose any information which is subject
to the foregoing confidentiality restriction pursuant to clause (b)(ii) or
(b)(iii) above, such Representative will notify the Company, to the extent
practicable, so that the Company may seek an appropriate protective order. If
requested by the Company, each Representative will acknowledge in writing that
he is aware that the United States securities laws prohibit any Person who has
material non-public information about a company with securities registered under
the Exchange Act from purchasing or selling securities of such company based on
such non-public information or disclosing such information to any other Person
under circumstances where it is reasonably foreseeable that other such Person is
likely to sell securities of such company based on such non-public information.

     Section 5.12. Controlling Provisions. If any provision of this Article V
conflicts with or is contrary to any other provision of this Agreement, such
provision of this Article V shall govern and control.

     Section 5.13. Indemnification. The Holders shall indemnify and save each
Representative harmless against any Claims, Liabilities and Losses, not arising
from his own gross negligence or intentional misconduct, which such
Representative may incur in the good faith exercise and performance of his
powers and responsibilities hereunder.

                                   ARTICLE VI

                         CONCERNING THE REVIEW COMMITTEE

     Section 6.01. General. A committee (the "Review Committee") shall be
established for the purpose of meeting on a periodic basis (no less frequently
than once during each calendar quarter unless all of the members of the Review
Committee shall otherwise agree) to review and discuss the management, operation
and development of the Business Units and related Assets. In connection with its
preparation of any business plan for the management, development and operation
of the Business Units and related Assets or any amendment thereto, the Company
will consult with the Review Committee for the purpose of seeking advice and
recommendations from the Review Committee regarding such business plan or
amendment thereto. Promptly after each business plan (or amendment thereto) is
finalized, the Company will provide each member of the Review Committee with a
copy

                                       43

<PAGE>

thereof. It is understood and agreed that the object of each such business plan
will be to maximize the value of the Business Units and related Assets. The
reasonable fees of, and the reasonable costs and expenses incurred by, the
Review Committee and its members in furtherance of their responsibilities shall
be borne by the Company and fairly allocated among the Business Units for
purposes of determining the Excess Cash Flow of the Business Units, such
allocation to be made in a manner reasonably determined by the Company in good
faith.

     Section 6.02. Composition. The Review Committee shall be composed of five
members. Two members shall be designated by the Company (the "Company Members")
and two members shall be designated by the Representatives (the "Holder
Members"). The Company Members and the Holder Members shall jointly appoint a
fifth member (the "Independent Member") who shall be independent and, as such,
shall not be an Associate of the Company or any Holder. Each Company Member may
be an officer, employee or consultant of the Company. Each member of the Review
Committee shall be experienced in, and shall be generally recognized as having
current competence in, the management and development of residential and
commercial properties similar to the Assets comprising the Business Units.

     Section 6.03. Resignation and Removal. (a) Any member of the Review
Committee may at any time resign and be discharged of his duties and obligations
hereunder by giving prior written notice to the Company, the Representatives and
the other members of the Review Committee.

     (b) The Company shall have the exclusive right at any time, with or without
cause, to remove each Company Member by giving written notice to the
Representatives and the other members of the Review Committee, which notice
shall name the individual appointed by the Company to succeed such member. If
either Company Member shall die or resign, the Company shall have the exclusive
right to appoint a successor by giving written notice to the Representatives and
the other members of the Review Committee. If the Company fails to appoint a
successor within 15 days of becoming aware of such death or resignation, the
remaining members of the Review Committee shall be deemed to constitute the
Review Committee until such time as the Company appoints a successor as
aforesaid.

     (c) The Representatives shall have the exclusive right at any time, with or
without cause, to remove each Holder Member by giving written notice to the
Company and the other members of the Review Committee, which notice shall name
the individual appointed by the Representatives to succeed such member. If
either Holder Member shall die or resign, the Representatives shall have the
exclusive right to appoint a successor by giving written notice to the Company
and the other members of the Review Committee. If the Representatives fail to
appoint a successor within 15 days of becoming aware of such death or
resignation, the remaining members of the Review Committee shall be deemed to
constitute the Review Committee until such time as the Representatives appoint a
successor as aforesaid.

     (d) The Company Members and the Holder Members, acting unanimously, shall
have the exclusive right at any time, with or without cause, to remove the
Independent Member by giving written notice to the Representatives and the
Company, which notice shall name the individual unanimously appointed by the
Company Members and the Holder Members to succeed such Independent Member. If
the Independent Member shall die or resign, the Company Members and the Holder
Members, acting unanimously, shall have the exclusive right to appoint a
successor by giving written notice to the Representatives and the Company. If
the Company Members and the Holder Members fail to unanimously appoint a
successor Independent Member within 15 days of becoming aware of such death or
resignation, any Company Member or Holder Member may apply to any court of
competent jurisdiction to appoint a successor Independent Member, and such court
may thereupon, after such notice (if any) as it may consider proper, appoint a

any employee, agent, advisor, consultant, officer, director or stockholder of

     (b) disclose and use any such documents or other information (i) as the
Company shall approve from time to time (which approval shall not be

subpoena or in connection with any litigation, (iii) to the extent such member
believes it necessary to comply with applicable Law or (iv) to the extent such
member believes it necessary in the performance of his duties and obligations

remedies or immunities hereunder.

If any member of the Review Committee intends to disclose any information which
is subject to the foregoing confidentiality restriction pursuant to clause
(b)(ii) or (b)(iii) above, such member of the Review Committee will notify the
Company, to the extent practicable, so that the Company may seek an appropriate
protective order. If requested by the Company, each member of the Review
Committee will acknowledge in writing that he is aware that the United States
securities laws prohibit any Person who has material non-public information
about a company with securities registered under the Exchange Act from
purchasing or selling securities of such company based on such non-public
information or disclosing such information to any other Person under

sell securities of such company based on such non-public information.

member of the Review Committee harmless against any Claims, Liabilities and
Losses, not arising from his own default, gross negligence or intentional
misconduct, which such member may incur in the good faith exercise and
performance of his powers and responsibilities hereunder.

     Section 7.02. Dispute Resolution. (a) In the event of any dispute between
the Company, on the one hand, and the Representatives, on the other hand, with
respect to any matter covered by this Agreement (including whether the
provisions of this Agreement have been complied with), the Company and the
Representatives (the "Disputants") shall first use their best efforts to resolve
such dispute between themselves. If the Disputants are unable to resolve the
dispute within 15 days, they agree to submit the dispute to mediation in
accordance with the Commercial Mediation Rules of the American Arbitration
Association. The Disputants will jointly appoint a mutually acceptable mediator,
seeking assistance in such regard from the American Arbitration Association if
they are unable to agree upon such appointment within ten days following the
15-day period referred to above. Upon appointment of the mediator, the
Disputants agree to participate in good faith in the mediation and negotiations
relating thereto for 20 days. If the Disputants are not successful in resolving
the dispute through mediation within such 20-day period, either Disputant may
submit the dispute to arbitration in accordance with the following provisions of
this Section 7.02. The fees and expenses of the mediator shall be borne by the
non-prevailing party or, in the event there is no clear prevailing party, as the
mediator deems appropriate.

     (b) To submit a dispute to arbitration as contemplated by paragraph (a)
above, a Disputant must give written notice to the other Disputant, in which
event the dispute shall be settled by arbitration in accordance with the
Expedited Procedures of the Commercial Arbitration Rules of the American
Arbitration Association except as otherwise provided below. The arbitrators
shall have sole discretion with regard to the admissibility of evidence. Each
Disputant shall have the right to be represented by counsel. All rulings of the
arbitrators shall be in writing, shall be determined by at least a majority of
their number and shall be delivered to the Disputants. The fees and expenses of
the arbitrators shall be borne by the non-prevailing Disputant or, in the event
there is no clear prevailing Disputant, as the arbitrators deem appropriate.

     (c) In the event there is any disputed question of law involved in any
arbitration proceeding hereunder, such as the proper legal interpretation of any
provision of this Agreement, the arbitrators shall make separate and distinct
findings of all facts material to the disputed question of law to be decided
and, on the basis of the facts so found, express their conclusion of the
question of law. The facts so found shall be conclusive and binding on the
Disputants, but any legal conclusion reached by the arbitrators from such facts
may be submitted by either Disputant to a court of law for final determination
by initiation of a civil action in the manner provided by law. Such action, to
be valid, must be commenced within 20 days after receipt of the arbitrators'
decision. If no civil action is commenced within such 20-day period, the legal
conclusion reached by the arbitrators shall be conclusive and binding on the
Disputants. Any such civil action shall be submitted, heard and determined
solely on the basis of the facts found by the arbitrators. Neither of the
Disputants shall, or shall be entitled to, submit any additional or different
facts for consideration by the court. In the event any civil action is commenced
under this paragraph (c), the party who prevails or substantially prevails (as
determined by the court) in such civil action shall be entitled to recover from
the other party all of its Losses incurred in connection with such action and on
appeal.

     (d) Except as limited by paragraph (c) above, the Disputants agree that
judgment upon the award rendered by the arbitrators may be entered in any court
of competent jurisdiction, and the Disputants hereby consent and commit
themselves to the jurisdiction of the courts of the State of Delaware and the
United States District Court for New Castle County, Delaware for purposes of the
enforcement of any arbitration award. In the event legal proceedings are
commenced to enforce the rights awarded in any arbitration proceeding hereunder,
the party who prevails or substantially prevails (as determined by the court) in
such legal proceeding shall be entitled to recover from the other party all of
its Losses incurred in connection with such legal proceeding and on appeal.

     (e) All arbitration conferences and hearings pursuant to this Section 7.02
shall be conducted in Wilmington, Delaware or at such other place as the
Disputants may mutually agree.

     Section 7.03. Benefit and Burden. (a) This Agreement shall inure to the
benefit of and shall be binding upon, the Parties and their respective
executors, personal representatives, administrators, successors, heirs,
distributees, devisees, legatees and permitted assigns.

     (b) Anything herein or elsewhere to the contrary notwithstanding, all
covenants and agreements on the part of the Company herein are hereby declared
to be for the benefit of the Holders and the Representatives and their
respective executors, personal representatives, administrators, successors,
heirs, devisees, legatees and permitted assigns, and each such Person shall be
entitled to enforce this Agreement the same as if it

                                       47

<PAGE>

were a signatory hereto. Nothing in this Agreement is intended to, or shall,
preclude or restrict any Holder from instituting and maintaining in his or its
own name such suits and proceedings as such Person may deem necessary to enforce
delivery of all Contingent Shares and Contingent Preferred Shares which such
Person is entitled to receive hereunder or to otherwise protect and enforce such
Person's rights, privileges and interests hereunder.

     Section 7.04. Consolidations, Mergers, Etc. (a) The Company will require
any successor (whether direct or indirect, by purchase, merger, consolidation or
otherwise) to all or substantially all of the business and/or Assets of the
Company, by agreement in form and substance reasonably acceptable to the
Representatives, to expressly assume and agree to perform this Agreement in the
same manner and to the same extent that the Company would be required to perform
it if no such succession had taken place. Failure of the Company to obtain such
agreement prior to the effectiveness of any such succession shall be a material
breach of this Agreement. As used herein, the term "Company" shall include any
successor to its business and/or Assets as aforesaid which executes and delivers
the agreement provided for in this paragraph (a) or which otherwise becomes
bound by all the terms and provisions of this Agreement by operation of Law.

     (b) The Company acknowledges that this Agreement and the rights of the
Holders hereunder (including (i) the right of the Holders to receive securities
which are freely tradable and readily marketable and (ii) the non-taxable
receipt by the Holders of Rouse Common Stock pursuant to the Merger and of
Contingent Shares hereunder) are of major importance to the Holders and that
each Holder is justified in believing and assuming that the Company will not
voluntarily undertake or complete any Prohibited Transaction. The Company
expressly agrees that, without the prior written consent of the Majority
Holders, it will not undertake or complete any Prohibited Transaction. As used
herein, "Prohibited Transaction" means (A) any reorganization of the Company or
any consolidation or merger of the Company with or into another entity, (B) any
recapitalization, reclassification or change in the capital structure of the
Company, (C) any partial or complete liquidation, dissolution or winding up of
the affairs of the Company or (D) any other transaction or event if, in any such
case and for any reason, (i) the Company or any successor to the Company shall
be incapable of, or restricted or prohibited from, delivering (on a timely
basis) freely tradable and readily marketable securities comparable to the
Contingent Shares or the Contingent Preferred Shares (as applicable) hereunder
or (ii) such transaction or event could reasonably be expected to have a
prejudicial effect on the Holders with respect to their non-taxable receipt of
securities pursuant to the Merger Agreement or this Agreement.

     (c) In the event the Company desires to implement any transaction of the
type described in clauses (A) through (D) of paragraph (b) above which the
Company has concluded, in good faith, does not constitute a Prohibited
Transaction (a "Proposed Transaction"), the Company shall, as soon as
practicable prior to the implementation of the Proposed Transaction, give
written notice to the Representatives describing the Proposed Transaction in
reasonable detail and setting forth the Company's conclusion that the Proposed
Transaction does not constitute a Prohibited Transaction and the reasons
therefor. Such notice may also contain a request that the Representatives agree
with the conclusion set forth therein. Upon receipt of any such request, the
Representatives shall consider the same in good faith and shall be authorized
(but not obligated) to agree, on behalf of the Holders, with the Company's
conclusion that the Proposed Transaction does not constitute a Prohibited
Transaction. Any such agreement of the Representatives (i) shall be in writing,
(ii) shall be limited to the Proposed Transaction in question and shall not
extend or apply to any other transaction or event and (iii) may be conditioned
upon and subject to the execution and delivery to the Representatives of one or
more instruments in writing designed to fairly and equitably protect the rights,
privileges, interests and remedies of the Holders and the Representatives
against one or more effects of the Proposed Transaction. Moreover, each such
agreement of the Representatives shall be binding upon the Holders and, in the
absence of fraud or bad faith, the Company shall be fully protected for purposes
of this Section 7.04 in acting in accordance with such agreement.

     (d) Nothing in this Section 7.04 shall relieve the Company of any of its
obligations contained elsewhere in this Agreement.

     Section 7.05. Company as Fiduciary. (a) The Company acknowledges and agrees
that it is accountable as a fiduciary to the Holders and their respective
executors, personal representatives, administrators, successors, heirs,
distributees, devisees, legatees and permitted assigns, which fiduciary duty
shall be the same as the fiduciary duty owed by a director of a corporation to
the stockholders of such corporation. Without limitation of the foregoing, the
Company shall, and shall cause each Business Unit Entity to, (i) exercise
reasonable care and act with

                                       48

<PAGE>

good faith and integrity in managing and operating the Business Units and the
Assets comprising the Business Units and (ii) deal with the Holders and the
Representatives fairly and in good faith.

     (b) Except as provided in Section 4.03, no obligation or covenant imposed
on the Company by this Agreement, including under Sections 4.10, 4.11, 4.12 and
4.13, shall be construed to obligate the Company or any of its Subsidiaries in
any way to make loans to, advance funds to, invest additional capital in or
extend its credit in order to obtain financing for, or provide working capital
for, any Business Unit or any Business Unit Entity, except in its sole and
absolute discretion. The Company makes no representation or warranty that the
operation of any Business Unit or any portion of the Assets of any Business Unit
shall be profitable or that any Business Unit will have Receipts sufficient to
obligate the Company to deliver Contingent Shares hereunder.

     Section 7.06. No Third Party Rights. Nothing in this Agreement shall be
deemed to create any right in any creditor or other Person other than the
Parties, the members of the Review Committee and the other Persons referred to
in Section 7.03(a), and this Agreement shall not be construed in any respect to
be a Contract in whole or in part for the benefit of any Person other than the
Parties, the members of the Review Committee and the other Persons referred to
in Section 7.03(a).

     Section 7.07. Amendments and Waiver. (a) Except as provided in Section
4.02, this Agreement may be not be amended, supplemented or modified, nor may
compliance by the Company with any provision of this Agreement be waived (either
generally or in a particular instance and either retroactively or
prospectively), except in each case by an instrument in writing duly entered
into by the Company and all of the Representatives. Without limitation of the
foregoing, the Representatives may, without the consent of any of the Holders,
enter into one or more instruments supplemental hereto as they may deem
desirable in order to (i) add to the covenants of the Company in this Agreement,
(ii) surrender any right or power conferred upon the Company by this Agreement,
(iii) evidence any succession of any Person to the Company and the assumption by
such successor of the covenants of the Company contained herein, (iv) cure any
ambiguity in (or cure, correct or supplement any defective provision of) this
Agreement in such manner as shall not be inconsistent with this Agreement or
adversely affect the rights, privileges or remedies of the Holders under this
Agreement. Notwithstanding the foregoing, no such amendment, supplement,
modification or waiver will be effective:

               (A) except as provided in clause (B) below, without the prior
          written consent of the Majority Holders, if such amendment,
          supplement, modification or waiver would (1) add any provision to this
          Agreement, change in any manner or eliminate any of the provisions of
          this Agreement or modify in any respect the rights of the Holders
          under this Agreement, in each case if such addition, change,
          elimination or modification would materially and adversely affect the
          rights, privileges or remedies of the Holders under this Agreement, or
          (2) waive any Event of Default;

               (B) without the prior written consent of all the Holders, if such
          amendment, supplement, modification or waiver would (1) change the
          amount of, or times for the delivery of, Contingent Shares or
          Contingent Preferred Shares to be delivered by the Company under this
          Agreement in a manner adverse to the Holders, (2) change the Valuation
          Date of any Business Unit, (3) reduce the Percentage Interest of any
          Holder (other than due to an assignment to an Eligible Assignee), (4)
          substitute any Equity Interest for the Contingent Shares or Contingent
          Preferred Shares required to be delivered by the Company under this
          Agreement (unless otherwise specifically permitted in this Agreement),
          (5) waive any Event of Default under clause (b) of the definition
          thereof or (6) change the provisions of this Section 7.07 (except to
          increase any percentage required to approve any such amendment,
          supplement, modification or waiver or to provide that certain other
          provisions of this Agreement cannot be amended, supplemented, modified
          or waived without the consent of all of the Holders affected thereby);

               (C) without the prior written consent of all members of the
          Review Committee, if such amendment, supplement, modification or
          waiver would adversely affect the rights, duties or immunities of the
          members of the Review Committee under this Agreement; or

                                       49

<PAGE>

               (D) without the prior written consent of all of the
          Representatives, if such amendment, supplement, modification or waiver
          would adversely affect the rights, duties or immunities of the
          Representatives under this Agreement.

Notwithstanding anything to the contrary contained herein, Article V of this
Agreement may be amended, supplemented or modified at any time solely by an
instrument in writing signed (x) by the Representatives with the consent of the
Majority Holders and (y) if and to the extent that such amendment, modification
or supplement would in any way be prejudicial to the Company, by the Company. In
the case of any amendment, supplement, modification or waiver referred to in
clause (x) above, it shall not be necessary for the Majority Holders to approve
the particular form of such amendment, supplement, modification or waiver, but
it shall be sufficient if the Majority Holders shall approve the substance
thereof. Similarly, in the case of any amendment, supplement, modification or
waiver referred to in clause (y) above, it shall not be necessary for the
Holders to approve the particular form of such amendment, supplement,
modification or waiver, but it shall be sufficient if the Holders shall approve
the substance thereof. No such amendment, supplement, modification or waiver
shall extend to or affect any provision, term or obligation not expressly
amended, supplemented, modified or waived thereby or impair any right consequent
thereon. Any amendment, supplement, modification or waiver entered into pursuant
to this paragraph (a) shall be binding upon all Parties. Copies of each
amendment, supplement, modification or waiver entered into pursuant to this
paragraph (a) shall be delivered by the Company to each of the Representatives
and each Holder.

     (b) The Company will not, directly or indirectly, pay or cause to be paid
any remuneration (whether in the form of a fee or otherwise) to any Holder as
consideration for or as an inducement to such Holder's consenting to any
proposed amendment, supplement, modification or waiver of this Agreement unless
such remuneration is concurrently paid, on the same terms, ratably to all the
Holders.

     (c) No failure or delay on the part of any Party in exercising any right,
power or privilege hereunder and no course of dealing between or among any of
the Parties shall operate as a waiver of any right, power or privilege
hereunder. No single or partial exercise of any right, power or privilege
hereunder shall preclude any other or further exercise thereof or the exercise
of any other right, power or privilege hereunder. No notice to or demand on any
Party in any case shall entitle such Party to any other or further notice or
demand in similar or other circumstances or constitute a waiver of the rights of
any Party to any other or further action in any circumstances without notice or
demand.

     (d) None of the expenses (including, without limitation, counsel fees and
expenses) incurred by the Company or any Business Unit Entity in connection with
any amendment, supplement, modification or waiver of this Agreement shall be
deemed an Expenditure hereunder unless otherwise consented to by the
Representatives in writing.

     Section 7.08. Further Documents. The Company agrees to execute any and all
documents, and to perform any and all other acts, as may be necessary or
reasonably requested by the Representatives to accomplish the purposes of this
Agreement.

     Section 7.09. Assignments. (a) Except for a Transfer by a Holder to an
Eligible Assignee or as permitted by Section 7.04, neither this Agreement nor
any right, interest or obligation hereunder may be assigned by (i) by the
Company without the prior written consent of the Representatives or (ii) by any
Holder, and any attempt to do so shall be null and void.

     (b) Except as otherwise provided herein or prohibited by applicable law,
the Company may acquire from any Holder all (but not less than all) of the
rights and interests of such Holder hereunder; provided, however, that (i)
voting or consensual rights of such Holder hereunder shall automatically expire
and terminate concurrently with the assignment to the Company of the rights and
interests of such Holder hereunder and (ii) in no event shall the Company or any
Subsidiary or Affiliate of the Company acquire the rights and interests of a
Holder hereunder prior to December 31, 1997.

     Section 7.10. Severability. Should any clause, sentence, paragraph,
subsection, Section or Article of this Agreement be judicially declared to be
invalid, unenforceable or void, such decision will not have the effect of
invalidating or voiding the remainder of this Agreement, and the part or parts
of this Agreement so held to

                                       50

<PAGE>

be invalid, unenforceable or void will be deemed to have been stricken herefrom,
and the remainder will have the same force and effectiveness as if such stricken
part or parts had never been included herein.

     Section 7.11. Specific Performance. The covenants and obligations contained
in this Agreement relate to special, unique and extraordinary matters and a
violation of any of the terms hereof or thereof by the Company would cause
irreparable injury to the Holders and/or the Representatives in an amount which
would be impossible to estimate or determine and for which any remedy at law
would be inadequate. As such, the Company agrees that if the Company fails or
refuses to fulfill any of its obligations under this Agreement or to make any
payment or deliver any instrument required hereunder, then the Holders and/or
the Representatives shall have the remedy of specific performance, which remedy
shall be cumulative and nonexclusive and shall be in addition to any other
rights and remedies otherwise available under any other Contract or at law or in
equity and to which the Holders and/or the Representatives might be entitled.

     Section 7.12. APPLICABLE LAW. THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS
OF THE COMPANY HEREUNDER SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH
THE LAWS OF THE STATE OF DELAWARE, WITHOUT GIVING EFFECT TO THE CONFLICT OF LAW
PRINCIPLES THEREOF.

     Section 7.13. Submission to Jurisdiction. The Company hereby irrevocably
and unconditionally consents to submit to the exclusive jurisdiction of the
courts of the State of Delaware and the United States of America located in the
State of Delaware (the "Delaware Courts") for any litigation arising out of or
relating to this Agreement and the transactions contemplated hereby (and agrees
not to commence any litigation relating thereto except in a Delaware Court),
waives any objection to the laying of venue of any such litigation in any
Delaware Court and agrees not to plead or claim that any litigation brought in
any Delaware Court has been brought in an inconvenient forum; provided, however,
that nothing contained in this Section 7.13 is intended to waive the right of
the Company to remove any action or proceeding commenced in any state Delaware
Court to an appropriate federal Delaware Court to the extent the basis for such
removal exists under applicable Law. The Company hereby irrevocably (i) appoints
The Corporation Trust Company (the "Process Agent"), with an office on the date
hereof at 1209 Orange Street, Wilmington, Delaware 19801, as its agent to
receive on behalf of it and its Assets service of copies of the summons and

this Agreement, if a Trigger Event has occurred, for a period that is 180 days following the later
of (i) the first anniversary of the Operative Date and (ii) the occurrence of such Trigger Event,
the Qualified Holders may, subject to Sections 2.2 and 2.4, request registration
under the Securities Act of the Registrable Securities (a “Demand Registration”). The
request for a Demand Registration shall specify the number of Registrable Securities requested to
be registered and the intended method of distribution; provided, however, that
Parent shall not be obligated to effect a Demand Registration unless the Qualified Holders request
that Parent register Registrable Securities representing in the aggregate at least 5% of the
outstanding Parent Common Stock. Within ten days after receipt of any such request, Parent shall
give written notice of such requested registration to all other holders of Registrable Securities
and, subject to Section 2.3, shall include as part of such Demand Registration all
Registrable Securities with respect to which Parent has received written requests for inclusion
therein within 15 days after the receipt of Parent’s notice by such holders.

Agreement shall be deemed to have been effected for purposes of Section 2.1 if (i) it has
been declared effective by the Commission and (ii) at least 75% of the Registrable Securities
requested to be included in such registration shall have been registered and sold.

3

 

          2.3 Priority on Demand Registration. If a Demand Registration is an underwritten
offering and the managing underwriters advise Parent in writing, with a copy to be delivered to the
Qualified Holders, that, in their opinion, the number of Registrable Securities requested to be
included in such offering, and other securities requested to be included in such offering, exceeds
the largest number of securities which can be sold therein without adversely affecting the
marketability of the offering and within a price range reasonably acceptable to the holders of a
majority of the Registrable Securities requested to be registered, Parent shall first include in
such registration, prior to the inclusion of any securities which are not Registrable Securities,
the Registrable Securities requested to be included which in the opinion of such underwriters can
be sold without adversely affecting the marketability of the offering, pro rata
among the respective holders thereof on the basis of the amount of Registrable Securities owned by
each such requesting holder.

          2.4 Restrictions on Registration. Parent may postpone or suspend, as applicable, for
no more than one period of up to 90 days in any 12-month period the filing, effectiveness or use of
a registration statement for a Demand Registration (and the holders of Registrable Securities
participating in such offering hereby agree not to offer or sell any Registrable Securities
pursuant to such registration statement during such postponement or suspension), pursuant to
this Section 2.4 or clause (iii) of Section 5.2, if Parent determines in good faith
that such filing or effectiveness might (a) interfere with or adversely affect the negotiation or
completion of any material transaction or other material event that is being contemplated by Parent
or (b) involve initial or continuing disclosure obligations relating to a material event or
material state of facts regarding Parent the disclosure of which would, in the reasonable judgment
of Parent, be adverse to its interests; provided, that, in the event of such a
postponement or suspension of registration, the holders of Registrable Securities initially
requesting such Demand Registration shall be entitled to withdraw such request and, if such request
is withdrawn, such Demand Registration shall not count as the Demand Registration hereunder. In
the event Parent shall exercise its postponement or suspension rights hereunder, (x) the applicable
time period during which a registration statement is to remain effective under Section 5.2
and the 180-day period specified in Section 2.1 shall be extended by a period of time equal
to the duration of such postponement or suspension. The number and length of suspension and
postponement periods in any 12-month period under this Section 2.4 shall be aggregated with
the number and the length of Suspension Periods under clause (iii) of Section 5.2, such
that Parent shall not be permitted to postpone or suspend, for more than 90 days in such 12-month
period the filing, effectiveness or use of a registration statement for a Demand Registration
pursuant to Section 2.4 and/or clause (iii) of Section 5.2 taken together.

          2.5 Selection of Underwriters. In the event that any public offering pursuant to a
Demand Registration shall involve, in whole or in part, an underwritten offering, Parent shall have
the right to designate a nationally recognized underwriter or underwriters as the lead or managing
underwriter(s) of such underwritten offering who shall be reasonably acceptable to the holders of a
majority of the Registrable Securities proposed to be sold in such underwritten offering. The
Stockholders and Parent agree that if the Stockholders’ Registrable Securities, or any portion
thereof, are sold in any public offering involving, in whole or in part, an underwritten offering,
then the Stockholders and Parent will enter into a customary underwriting agreement with the
underwriter(s) selected pursuant to the preceding sentence.

     3. Piggyback Registration.

          3.1 Right to Piggyback. If on or after the first anniversary of the Operative Date
and prior to the 18 month anniversary of the Operative Date, Parent proposes to register Parent
Common Stock (for its own account or for the account of any other holder of its securities) under
the Securities Act (other than pursuant to a Demand Registration which shall be governed by
Section 2, and registrations on Form S-4 (or F-4) or Form S-8 or on any successor or other
form promulgated for similar purposes or relating to a Rule 145 transaction) and the registration
form to be used may be used for the registration of Registrable Securities for sale to the public
under the Securities Act (a “Piggyback Registration”), the Company shall give prompt
written notice to all holders of Registrable Securities of its intention to effect such a
registration and, subject to the terms hereof, shall use commercially reasonable efforts to include
in such registration all Registrable Securities with respect to which the Company has received
written requests for inclusion therein (which request shall specify the number of Registrable
Securities intended to be disposed of by such Holder) within 21 days after such holders receive the
Company’s notice; provided, that (i) if, at any time after giving written notice of its
intention to register any securities and prior to the effective date of the registration statement
filed in connection with such registration, the Company shall determine for any reason not to
proceed with the proposed registration, the Company may, at its election, give written notice of
such determination to each holder of Registrable Securities and thereupon shall be relieved of its
obligation to register any Registrable Securities in connection with such registration and (ii) if
such registration involves an underwritten offering by the Company, all holders requesting to be
included in the Company’s registration must sell their Registrable Securities to such underwriters
who shall have been selected by the Company on the same terms and conditions as apply to the
Company, with such differences, including any with respect to indemnification and contribution, as
may be customary or appropriate in combined primary and secondary offerings.

          3.2 Priority on Primary Registrations. If a Piggyback Registration is an underwritten
primary offering on behalf of the Company, and the managing underwriters advise the Company in
writing that in their opinion the number of securities requested to be included in such offering
exceeds the largest number of securities which can be sold therein without adversely affecting the
marketability of the offering and within a price range reasonably acceptable to the Company, the
Company shall include in such registration (a) first, the securities the Company proposes to sell,
(b) second, the Registrable Securities requested to be included in such registration, pro
rata among the respective holders thereof on the basis of the amount of Registrable
Securities owned by each such holder and (c) third, other securities requested to be included in
such registration.

          3.3 Selection of Underwriters. The Company shall have the right to select the
investment banker(s) and/or manager(s) to administer the offering in connection with any Piggyback
Registration.

          3.4 Other Agreements. Each holder of Registrable Securities agrees that, if they
participate in the Piggyback Registration, they will execute such other customary agreements as the
Company may reasonably request to further accomplish the purposes of this Section 3.

5

 

     4. Holdback Agreements. Upon the written request of the underwriters managing an
underwritten registered public offering of Parent Common Stock pursuant to a Demand Registration
or a Piggyback Registration in which Registrable Securities are included, the holders of
Registrable Securities shall not effect any public sale or distribution (including sales pursuant
to Rule 144) of equity securities of Parent, or any securities convertible into or exchangeable or
exercisable for such securities, during the 7 days prior to, and during the 90-day period beginning
on, the effective date of such Demand Registration or Piggyback Registration (or such shorter
period as may be required for officers and directors of Parent).

     5. Registration Procedures. Whenever the holders of Registrable Securities have
properly requested that any Registrable Securities be registered pursuant to this Agreement, Parent
shall use commercially reasonable efforts to effect the registration under the Securities Act of
the sale of such Registrable Securities in accordance with the intended method of disposition
thereof, and pursuant thereto Parent shall as expeditiously as possible:

          5.1 prepare and file with the Commission a registration statement and such amendments and
supplements as may be necessary with respect to such Registrable Securities and, subject to the
postponement and suspension provisions of Sections 2.4 and 5.2, use its
commercially reasonable efforts to cause such registration statement to become effective;

          5.2 notify each holder of Registrable Securities of the effectiveness of the registration
statement filed hereunder and prepare and file with the Commission such amendments and supplements
to such registration statement and the prospectus used in connection therewith as may be necessary
to keep such registration statement effective for a period of not less than 30 days (or until the
distribution described in the registration statement has been completed or such lesser period of
time as Parent or any seller may be required under the Securities Act to deliver a prospectus in
connection with any sale of Registrable Securities and to comply with the provisions of the
Securities Act with respect to the disposition of all securities covered by such registration
statement during such period in accordance with the intended methods of disposition by the sellers
set forth in such registration statement); provided, however, that at any time,
upon written notice to the participating holders of Registrable Securities, Parent may suspend the
use or effectiveness of any registration statement (and the holders of Registrable Securities
participating in such offering hereby agree not to offer or sell any Registrable Securities
pursuant to such registration statement during the Suspension Period) upon and continuing until the
discontinuation of (i) the issuance by the Commission of a stop order with respect to such
registration statement or the initiation of proceedings with respect to such registration statement
under Section 8(d) or 8(e) of the Securities Act, (ii) the occurrence of any event or the existence
of any fact as a result of which (A) any registration statement shall contain any untrue statement
of a material fact or omit to state any material fact required to be stated therein or necessary to
make the statements therein not misleading or (B) any prospectus included in any such registration
statement shall contain any untrue statement of a material fact or omit to state any 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 or (iii) the occurrence or existence of
any pending corporate development, including without limitation any such development that may
(y) interfere with or adversely affect the negotiation or completion of any material transaction or
other material event that is being contemplated by Parent or (z) involve initial or continuing
disclosure obligations relating to a material event or

6

 

material state of facts regarding Parent the disclosure of which would, in the reasonable
judgment of Parent, be adverse to its interests, that, in the reasonable discretion of Parent,
makes it appropriate to suspend the availability of any registration statement and the related
prospectus (each of (i), (ii) and (iii) above is hereinafter referred to as a “Suspension
Period”); provided that Parent’s right to suspend under clause (iii) above shall be
subject to the restrictions on the length of any suspensions or postponements in any 12-month
period set forth in Section 2.4 and shall be aggregated with the length of suspension and
postpone periods under Section 2.4, such that Parent shall not be permitted to postpone or
suspend, for more than 90 days in any 12-month period the filing, effectiveness or use of a
registration statement for a Demand Registration pursuant to Section 2.4 and/or clause
(iii) of this Section 5.2 taken together. In the event that Parent shall exercise its
rights hereunder, the applicable time period during which the registration statement is to remain
effective shall be extended by a period of time equal to the duration of the Suspension Period;

          5.3 furnish to each seller of Registrable Securities such number of copies of such
registration statement, each amendment and supplement thereto, the prospectus included in such
registration statement (including each preliminary prospectus) and such other documents as such
seller may reasonably request in order to facilitate the disposition of the Registrable Securities
owned by such seller;

          5.4 use commercially reasonable efforts to register or qualify such Registrable Securities
under such other securities or blue sky laws of such jurisdictions as may be reasonably requested
by any such seller and do any and all other reasonable acts and things which may be necessary or
reasonably advisable to enable such seller to consummate the disposition in such jurisdictions of
the Registrable Securities owned by such seller (provided, however, that Parent
shall not be required to (a) qualify generally to do business in any jurisdiction where it would
not otherwise be required to qualify but for this subsection, (b) subject itself to taxation in any
such jurisdiction or (c) consent to general service of process in any such jurisdiction);

          5.5 promptly notify each seller of such Registrable Securities, at any time when a prospectus
relating thereto is required to be delivered under the Securities Act, of the happening of any
event as a result of which the prospectus included in such registration statement contains an
untrue statement of a material fact or omits any material fact necessary to make the statements
therein, in light of the circumstances under which they were made, not misleading, and, at the
request of any such seller, Parent shall promptly prepare a reasonable number of copies of a
supplement or amendment to such prospectus so that, as thereafter delivered to the sellers of such
Registrable Securities, such prospectus shall not contain an untrue statement of a material fact or
omit to state any material fact necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading, in which event the periods mentioned in
Section 5.2 shall be extended by the length of the period from and including the date when
each seller of such Registrable Securities shall have received such notice to the date on which
each such seller has received the copies of the supplemented or amended prospectus contemplated
under this Section 5.5;

7

 

          5.6 use commercially reasonable efforts to cause all such Registrable Securities to be listed
on each securities exchange and/or quotation system on which Parent Common Stock is then listed
and/or quoted;

          5.7 provide a transfer agent and registrar for all such Registrable Securities not later than
the effective date of such registration statement;

          5.8 in the case of an underwritten offering, enter into such customary agreements (including
underwriting agreements in customary form) and take all such other actions as the underwriters, if
any, reasonably request in order to expedite or facilitate the disposition of such Registrable
Securities, except to the extent any such agreement or other action would materially interfere with
the conduct of Parent’s business;

          5.9 in the case of an underwritten offering, make available for inspection by any seller of
Registrable Securities, any underwriter participating in any disposition pursuant to such
registration statement, and any attorney, accountant or other agent retained by any such seller or
underwriter, at the offices where normally kept, during normal business hours, all pertinent
financial and other records, pertinent corporate documents and properties of Parent, and cause
Parent’s officers, employees and independent accountants to supply all information reasonably
requested by any such seller, underwriter, attorney, accountant or agent in connection with such
registration statement, in each case as is necessary or reasonably advisable (based on the
reasonable advice of their respective counsel) to enable such seller or underwriter to exercise
their due diligence responsibilities and defenses under the Securities Act; provided,
however, that (i) such sellers shall have entered into a customary confidentiality
agreement reasonably acceptable to Parent and (ii) such sellers shall use their reasonable best
efforts to minimize the disruption to Parent’s business and coordinate any such investigation of
the books, records and properties of Parent and any discussions with Parent’s officers and
accountants so that all such investigations occur at the same time;

          5.10 otherwise use commercially reasonable efforts to comply with all applicable rules and
regulations of the Commission, and make available to its security holders, as soon as reasonably
practicable, an earnings statement covering the period of at least twelve months beginning with the
first day of Parent’s first full calendar quarter after the effective date of the registration
statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities
Act and Rule 158 thereunder;

          5.11 in the event of the issuance of any stop order suspending the effectiveness of a
registration statement, or of any order suspending or preventing the use of any related prospectus
or suspending the qualification of any Company Common Stock included in such registration statement
for sale in any jurisdiction, Parent shall use its commercially reasonable efforts promptly to
obtain the withdrawal of such order;

          5.12 use its commercially reasonable efforts to cause such Registrable Securities covered by
such registration statement to be registered with or approved by such other governmental agencies
or authorities as may be necessary to enable the sellers thereof to consummate the disposition of
such Registrable Securities; and

8

 

          5.13 take such other actions reasonably requested by the sellers of Registrable Securities as
are necessary or reasonably advisable in order to facilitate and/or expedite the registration and
disposition of any Registrable Securities pursuant to the terms of this Agreement.

     6. Registration Expenses. All expenses incident to Parent’s performance of or
compliance with this Agreement, including, without limitation, all registration and filing fees
(including the fees of the Financial Industry Regulatory Authority and the Commission’s
registration fees), fees of any transfer agent and registrar, fees and expenses of compliance with
securities or blue sky laws, printing expenses, reasonable “road show” or other marketing expenses,
fees and disbursements of counsel for Parent, reasonable fees and disbursements of one counsel
chosen by the holders of a majority of the Registrable Securities included in such registration up
to a maximum of $50,000 if Parent does not trigger a Suspension Period and $75,000 if Parent does
trigger a Suspension Period, fees and expenses of Parent’s independent certified public accountants
(including the fees and expenses of any comfort letters required by or incident to the performance
and compliance with this Agreement), fees and expenses of underwriters (excluding discounts and
commissions attributable to the Registrable Securities included in such registration), Parent’s
internal expenses and the expenses and fees for listing the securities to be registered on each
securities exchange or quotation system on which similar securities issued by Parent are then
listed or quoted, shall be borne by Parent; provided, however, that the sellers of
Registrable Securities shall bear their own underwriting discounts or commissions, selling or
placement agent or broker fees and commissions, and transfer taxes, if any, in connection with the
sales of securities by such sellers.

     7. Indemnification.

          7.1 In connection with any Demand Registration or Piggyback Registration, Parent agrees to
indemnify, to the extent permitted by law, each holder of Registrable Securities to be offered in
such registration, the partners or officers, directors and equity holders of such holder, and each
Person who controls such holder (within the meaning of the Securities Act) against all losses,
claims, damages, liabilities (joint or several) and expenses (including legal or other expenses
reasonably incurred by any of them in connection with investigating or defending any such loss,
claim, damage or liability) incurred by such party arising out of, based upon or caused by any of
the following statements, omissions or violations (each, a “Violation”): (i) any untrue or
alleged untrue statement of material fact contained in any registration statement, prospectus or
preliminary prospectus incident to such registration or any amendment thereof, supplement thereto
or free writing prospectus, (ii) any omission or alleged omission of a material fact required to be
stated therein or necessary to make the statements therein, in light of the circumstances in which
they were made, not misleading, or (iii) any violation or alleged violation by Parent of the
Securities Act, the Exchange Act, any state securities laws or any rule or regulation promulgated
under the Securities Act, Exchange Act or any state securities laws incident to such registration;
provided, however, that Parent shall not be liable in any such case for any such
loss, claim, damage, liability or action to the extent that it is caused (x) by a Violation that
occurs in reliance upon and in conformity with any information furnished in writing to Parent by
such holder, and stated to be specifically for use in such registration or (y) by a seller’s
failure to deliver a copy of the relevant current prospectus or any amendments or

9

 

supplements thereto or any free writing prospectus after Parent has furnished that seller or
any underwriter with copies of the same in advance of the time of first sale.

          7.2 In connection with any Demand Registration or Piggyback Registration in which a holder of
Registrable Securities is participating, each such holder agrees to indemnify, to the extent
permitted by law, Parent, its directors, officers, employees, affiliates, any other holder selling
securities in such Demand Registration or Piggyback Registration, and each Person who controls
Parent (within the meaning of the Securities Act) against all losses, claims, damages, liabilities
(joint or several) and expenses (including legal or other expenses reasonably incurred by any of
them in connection with investigating or defending any such loss, claim, damage or liability)
arising out of, based upon or caused by any Violation, to the extent that such Violation is caused
by any information furnished in writing by such holder, and stated to be specifically for use in
such registration; provided, that, the obligation to indemnify shall be individual,
not joint and several, for each holder.

          7.3 Any Person entitled to indemnification hereunder shall (a) give prompt written notice to
the indemnifying party of any claim with respect to which it seeks indemnification (provided that
the failure to give prompt notice shall not impair any Person’s right to indemnification hereunder
to the extent such failure has not materially prejudiced the indemnifying party’s ability to defend
such claim), and (b) unless in the reasonable judgment (with advice of counsel) of any indemnified
party a conflict of interest between such indemnified and indemnifying parties exists with respect
to such claim, permit such indemnifying party to assume the defense of such claim with counsel
reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying
party shall not be subject to any liability for any settlement made by the indemnified party
without its consent (but such consent shall not be unreasonably withheld). An indemnifying party
who is not entitled to, or elects not to, assume the defense of a claim shall be obligated to pay
the fees and expenses of one counsel (but not more than one) for all parties indemnified by such
indemnifying party with respect to such claim.

          7.4 The indemnification provided for under this Agreement shall remain in full force and
effect regardless of any investigation made by or on behalf of the indemnified party or any
partner, officer, director or controlling Person of such indemnified party and shall survive the
transfer of securities.

          7.5 If the indemnification provided for under this Agreement is unavailable to an indemnified
party hereunder in respect of any losses, liabilities, claims, damages and expense referred to
herein, then the indemnifying party, in lieu of indemnifying such indemnified party, shall
contribute to the amount paid or payable by such indemnified party as a result of such losses,
claims, damages, liabilities or expenses in such proportion as is appropriate to reflect the
relative fault of the indemnifying party and indemnified parties in connection with the Violation
which resulted in such losses, claims, damages, liabilities or expenses, as well as any other
relevant equitable considerations. The relative fault of such indemnifying party and indemnified
parties shall be determined by reference to, among other things, whether any Violation has been
committed by, or relates to information supplied by, such indemnifying party or indemnified
parties, and the parties’ relative intent, knowledge, access to information and opportunity to
correct or prevent such Violation. The amount paid or payable by a party as a result of the
losses, claims, damages, liabilities and expenses referred to above shall be deemed to include any

10

 

legal or other fees or expenses reasonably incurred by such party in connection with any
investigation or proceeding. If the allocation provided in this paragraph is not permitted by
applicable law, the parties shall contribute based upon the relevant benefits received by Parent
from the offering of its securities on the one hand and the net proceeds received by the holders of
Registrable Securities from the sale of such Registrable Securities on the other.

          7.6 The parties hereto agree that it would not be just and equitable if contribution pursuant
to this Section 7 were determined solely by pro rata allocation or any other method of
allocation that does not take account of the equitable considerations referred to in the
immediately preceding paragraph. No person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

          7.7 Notwithstanding anything in this Section 7 to the contrary, in connection with the
Demand Registration or any Piggyback Registration, the indemnity and contribution obligations and
liabilities of each holder of Registrable Securities shall be limited to the net amount of the
proceeds received by such holder pursuant to such registration.

     8. Participation in Underwritten Registration. No Person may participate in any
registration hereunder which is underwritten unless such Person (a) agrees to sell such Person’s
securities on the basis provided in any underwriting arrangements that are customary and approved
by Parent and (b) completes and executes all questionnaires, powers of attorney and other documents
reasonably required under the terms of such underwriting arrangements.

     9. Information by Sellers. The seller or sellers wishing to sell any Registrable
Securities in any registration shall furnish to Parent such information regarding such seller or
sellers and the distribution proposed by such seller or sellers as Parent may reasonably request in
writing and as shall be required in connection with any registration, qualification or compliance
referred to in this Agreement.

     10. Termination. This Agreement shall terminate and neither party hereto shall have
any further obligation to the other party under this Agreement upon the earlier to occur of (a) the
time when there shall be no Registrable Securities remaining or (b) the completion of the Demand
Registration permitted hereunder; provided, however, that the obligations of the
parties under Section 7 hereof shall continue until the expiration of all applicable
statutes of limitations.

     11. Miscellaneous.

          11.1 Merger Agreement. If the Merger Agreement is terminated in accordance with its
terms, this Agreement shall immediately terminate concurrently therewith and be of no further force
or effect.

          11.2 No Inconsistent Agreements. Parent shall not hereafter enter into any agreement
with respect to its securities which is inconsistent with or violates the rights granted to the
holders of Registrable Securities in this Agreement.

          11.3 Remedies. Any Person having rights under any provision of this Agreement shall be
entitled to enforce such rights specifically, to recover damages caused by

11

 

reason of any breach of any provision of this Agreement and to exercise all other rights
granted by law. The parties hereto agree and acknowledge that money damages are not an adequate
remedy for any breach of the provisions of this Agreement and that any party may apply for specific
performance and for other injunctive relief in order to enforce or prevent violation of the
provisions of this Agreement.

          11.4 Amendments and Waivers. Except as otherwise provided herein, the provisions of
this Agreement may be amended or waived only upon the prior written consent of (a) Parent and (b)
the holders of a majority of the Registrable Securities then outstanding.

          11.5 Successors, Assigns and Subsequent Holders. (a) All covenants and agreements in
this Agreement by or on behalf of any of the parties hereto shall bind and inure to the benefit of
the respective successors and the permitted assigns of the parties hereto.

          (b) The rights to cause Parent to register Registrable Securities pursuant to this Agreement
may be assigned (but only with all related obligations) by a holder of Registrable Securities to a
transferee of such securities.

          (c) No assignment or transfer pursuant to this Section 11.5 shall be effective unless
and until (i) Parent is furnished with written notice of the name and address of such transferee or
assignee and the securities with respect to which such registration rights are being assigned, and
(ii) such transferee or assignee agrees in writing to be bound by and subject to the terms and
conditions of this Agreement.

          11.6 Entire Agreement. This Agreement constitutes the entire agreement of the parties
hereto with respect to the subject matter contained herein, and supersedes and preempts all prior
agreements, negotiations, discussions and understandings among the parties hereto with respect to
such subject matter.

          11.7 Severability. Wherever possible, each provision of this Agreement will be
interpreted in such manner as to be effective and valid under applicable law and in such a way as
to, as closely as possible, achieve the intended economic effect of such provision and this
Agreement as a whole, but if any provision contained herein is, for any reason, held to be invalid,
illegal or unenforceable in any respect, such provision shall be ineffective to the extent, but
only to the extent, of such invalidity, illegality or unenforceability without invalidating the
remainder of such provision or any other provisions hereof, unless such a construction would be
unreasonable.

          11.8 Notices. All notices or other communications required or permitted hereunder
shall be in writing and shall be deemed given upon delivery (a) when delivered personally, (b) if
transmitted by facsimile when confirmation of transmission is received, (c) if sent by registered
or certified mail, postage prepaid, return receipt requested or (d) if sent by reputable overnight
courier service (providing proof of delivery); and shall be addressed as follows:
