                                PARTNERSHIP INTERESTS

         3.1. In General.

              (a)  The Partnership has two (2) classes of Partnership 
Interest:  "General Partnership Interests," and "Class A Limited Partnership 
Interests," each of which shall be divided into units as provided in 
paragraph (c) below, which units shall evidence a Person's interest in a 
particular class of Partnership Interest.  The Class A Limited Partnership 
Interests are sometimes referred to herein as "Limited Partnership 
Interests."  The Partnership may create and issue additional classes of 
General or Limited Partnership Interests in accordance with Section 3.3 
hereof.

              (b)  Any Person may at the same time hold more than one class 
of Partnership Interest and, in such event, shall for the purposes of this 
Agreement be separately entitled to the rights afforded a Partner in each of 
such classes under this Agreement.  If a General Partner contributes to the 
capital of the Partnership as a Limited Partner or acquires any Limited 
Partnership Interest, it shall be treated in all respects as a Limited 
Partner as to such Limited Partnership Interests.

              (c)  Each class of Partnership Interest issued by the 
Partnership shall be divided into units ("Units") with each Unit within a 
class of Partnership Interest representing an equal undivided fractional 
share of each item of Partnership income, gain, and loss, and in each 
distribution of Partnership assets, allocable to the Units of that class of 
Partnership Interest. Accordingly, the General Partnership Interests shall be 
divided into GP Units and the Class A Limited Partnership Interests shall be 
divided into the Class A Units.  

              (d)  The aggregate total of Units for each class of Partnership 
Interest and the aggregate total of all Units outstanding shall be as set 
forth on Exhibit A attached hereto, as such Exhibit may be amended from time 
to time, and each Partner shall be deemed to hold those Units set forth next 
to such Partner's name on Exhibit A attached hereto.

         3.2. Class A Units.  The Class A Units shall be entitled to the 
rights of redemption specified in Article XV hereof and such voting and other 
rights as may be herein specified. Additional Class A Units are authorized 
for issuance in the future to acquire the Retained Interests as provided in 
Section 3.6, upon the achievement of Discounts as provided in Section 3.7, 
pursuant to the Option Agreement and as otherwise provided for or 
contemplated by this Agreement. 

                                         -14-


         3.3. Creation and Issuance of Additional Partnership Interests.  

              (a)  Subject only to the limitations expressly set forth in 
this Agreement, the General Partner is hereby authorized to cause the 
Partnership from time to time to solicit and accept additional Capital

limitation, in connection with the contribution of property to the 
Partnership) (i) additional Units representing General Partnership Interests 
and additional Units representing Class A Limited Partnership Interests, (ii) 
additional Partnership Interests and Units in one or more newly created 
classes of Partnership Interests, (iii) one or more series of any such 
classes of Partnership Interests (iv), rights, options, or warrants 
exercisable for or convertible into Partnership Interests, and (v) other 
securities or instruments of any type or class whatsoever.  Any of the 
foregoing may be issued for cash, property, services, or such other type, 
form, and amount of consideration (including notes, other evidences of 
indebtedness or obligations of the Person acquiring the interest, rights, 
instrument or security, as the case may be) as the General Partner may 
determine to be appropriate.  

              (b)  Each class of Partnership Interest newly created and 
issued hereunder, and any series within such class, shall have such rights, 
privileges, preferences and designations, and be subject to such limitations, 
as the General Partner shall specify in its sole discretion, including, 
without limitation, (i) the allocations of items of Partnership income, gain, 
loss, deduction and credit to each such class or series of Partnership 
Interest; (ii) the right of each such class or series of Partnership Interest 
to share in Partnership distributions; (iii) the rights of each such class or 
series of Partnership Interest upon dissolution and liquidation of the 
Partnership; (iv) the voting rights of such class or series; and (v) 
restrictions on transfer (in addition to the restrictions set forth in 
Section 11.1(b)).

              (c)  The creation of an additional class of Partnership 
Interest permitted hereunder, or series within any such class, may be made by 
the General Partner by setting forth either in an amendment or an addendum to 
this Agreement the relative rights, obligations, duties, and preferences of 
each new class, or series within any such class, of Partnership Interests 
created.  A copy of this Agreement as so amended, or the addendum as so 
adopted, as the case may be, shall be provided to each other Partner.  Any 
filings necessary to be made under the Act or applicable law in connection 
with the creation of such interests shall be made by the General Partner on 
behalf of the Partnership.

              (d)  No Limited Partner shall have any preemptive or 
preferential or similar right with respect to the issuance or sale of any 
Partnership Units.

         3.4. Issuance of Additional GP Units to General Partner.  If the 
General Partner issues additional Common Shares and contributes the net 
proceeds thereof as a Capital Contribution to the Partnership, then the 
Partnership shall issue to the General Partner additional 

                                         -15-



GP Units equal to the number of Common Shares issued by the General Partner, 
the net proceeds of which are contributed to the Partnership.

         3.5. Other Provisions Relating to All Classes of Partnership 
Interests.                 
   
              (a)  Fractional Units may be issued, with the amount of any 
such fractional interest being rounded to the fourth decimal place.

              (b)  By executing this Agreement, each Partner consents and 
authorizes the Partnership, acting solely through the General Partner, to 
issue, subject only to the express requirements hereof, such interests, 
instruments and securities upon such terms and conditions as the General 
Partner may from time to time determine to be appropriate.

              (c)  Certificates for Units may be issued, at the request of 
the holder of any Units, but no Class A Units comprising Collateral may be 
certificated prior to the time such Units cease to be Collateral hereunder 
unless the certificates are delivered to the holder of the first priority 
security interest thereon, duly endorsed in blank for transfer or accompanied 
by duly executed transfer powers.  

         3.6. Issuance of Class A Units Upon Exercise of Option to Acquire 
Retained Interests.

              (a)  The Nichols Company and Safeguard each hereby grants to

"Option Expiration Date").  The exercise notice shall contain the agreement 
of the Partnership to pay all Pennsylvania real estate transfer taxes that 
may become payable upon the transfer of such Retained Interest as a result of 
such option being exercised prior to the Option Expiration Date.

              (b)  If the option granted pursuant to Section 3.6(a) has not 
been exercised prior to the Option Expiration Date, then on the Option 
Expiration Date, the Partnership shall acquire from The Nichols Company and 
Safeguard, and The Nichols Company and Safeguard shall each Transfer to the 
Partnership, all Retained Interests described in paragraph (a), free and 
clear of any Encumbrance.

              (c)  Concurrently with the acquisition of the Retained

              (e)  The total number of Class A Units to be issued by the 
Partnership to acquire all of the Retained Interests and Class A Units of 
Witmer Partnership described in paragraphs (b) and (c) above shall be 44,322 
Class A Units.  At the closing for the Transfer of the Retained Interests and 
Class A Units of Witmer Partnership to the Partnership in accordance with the 
preceding paragraphs of this Section 3.6, the Partnership shall issue to 
Safeguard and The Nichols Company, or to their successors or designees, that 
number of such 44,322 Class A Units as is indicated opposite their names on 
Exhibit D and shall pay to each such person the amount, if any, that is equal 
to the aggregate amount that would have been distributed in respect of such 
Units had they been issued on the date hereof less any amounts distributed to 
such person after August 22, 1996 and prior to the date of such acquisition 
of the Retained Interests and Class A Units of Witmer Partnership from such 
person in respect of such person's Retained Interests and Class A Units of 
Witmer Partnership.  All such Class A Units shall be, when issued, validly 
issued, fully paid, and, except as otherwise required under the Act, 
nonassessable.

         3.7. Issuance of Additional Class A and GP Units Upon Achievement of 
Mortgage Discounts.

              (a)  If any Existing Mortgage Indebtedness is repaid or 
otherwise discharged or satisfied at a Discount as defined in Section 3.7(b), 
and as a result thereof additional net equity in the Property is realized, 
the Partnership shall issue the number of additional Class A Units and GP 
Units that is equal in the aggregate to (x) the dollar amount of the 
additional net equity so achieved divided by (y) $16.50 as adjusted in 
accordance with customary practice for stock splits, stock combinations and 
stock dividends occurring after the date hereof.  Twenty-five percent (25%) 
of such additional Units shall be GP Units and issued to the General Partner; 
and the remaining seventy-five percent (75%) of such additional Units shall 
be Class A Units and issued to the persons identified on Exhibit C under the 
column entitled "Name of Limited Partners Entitled to Receive Class A Units 
Upon Realization Discount", which persons shall receive such Units in the 
relative proportions indicated thereon.  

              (b)  For purposes of this Section 3.7, "Discount" shall be the 
amount greater than zero obtained by subtracting from (A) the outstanding 
principal balance of such 

                                         -17-



Existing Mortgage Indebtedness immediately prior to its repayment, (B) the 
amount of the cash paid, plus the fair value of any other assets conveyed, to 
fully discharge the Identified Indebtedness.  If such computation does not 
result in a number greater than zero, there shall be no Discount realized in 
the repayment of such Identified Indebtedness.

              (c)  For purposes of this Section 3.7, the additional net 
equity in a Property realized through the repayment of Mortgage Indebtedness 
at a Discount shall be the amount, greater than zero, obtained by (A) if the 
original net equity of the Property is positive, (i) adding the amount of the 
Discount to the original net equity of the Property shown on Exhibit C, and 
(ii) subtracting therefrom the original net equity assigned to the Property 
on Exhibit C; or (B) if the original net equity of the Property is negative, 
by subtracting from the Discount, the amount of such negative net equity.

              (d)  Whenever the Partnership shall issue additional Class A 
Units to any person under this Section 3.7, it shall pay to each such person 
the amount, if any, that is equal to the aggregate amount that would have 
been distributed in respect of such Units had they been issued on the date 
hereof.

              (e)  The persons identified on Exhibit C as being entitled to 
receive additional Units issuable under the circumstances set forth in this 
Section 3.7 shall remain entitled to receive any such Units notwithstanding 
that any such person may, after the date hereof, cease to be a Partner.

         3.8. Register.  The General Partner shall maintain a Register at the 
principal place of business of the Partnership setting forth the names and 
addresses and the number and class of Partnership Interests and Units held by 
each Partner.  Upon any adjustment or cancellation of any Partner's 
Partnership Interest and Units, the General Partner shall make such 
adjustment or cancellation in the Register and send written notice thereof to 
the Partner so affected.  Upon an assignment by a Partner of all or a part of 
its Partnership Interest and Units in the Partnership pursuant to the terms 
hereof and as permitted hereby, the General Partner shall register such 
assignment in the Register.  The General Partner shall note on the Register 
any restrictions on the transfer of all or any part of any Partner's 
Partnership Interest and Units and any such Units that are held in escrow 
hereunder.  In the absence of manifest error, the Register shall constitute 
conclusive evidence of the interest of each Partner and other Person in the 
Partnership Interests represented by the Units.

                                CAPITAL CONTRIBUTIONS

         4.1. Capital Contributions of the Partners.  

              (a)  As of the date hereof, each Partner owns the Partnership 
Interest represented by Units as set forth on Exhibit A attached hereto, 
which Exhibit may be amended from time to time by the General Partner to the 
extent necessary to reflect redemptions, conversions, additional Capital 
Contributions, the issuance of additional Partnership Interests and Units, or 
similar events having an effect on a Partner's ownership of a Partnership 
Interest and Units.    

              (b)  The Contributed Assets of the Partnership are indicated on 
Exhibit B hereof, which schedule may be amended from time to time by the 
General Partner to reflect additional contributions to the Partnership.

         4.2. Capital Contributions Generally.  Except as otherwise expressly 
provided herein or to the extent that a Partner agrees to make a Capital 
Contribution to, or to purchase Partnership Interests from, the Partnership:  
 no Partner shall be required to contribute any capital to the Partnership;  
no Partner may withdraw any of its capital from the Partnership;  no Partner 
shall be required to make any loan to the Partnership;  loans by a Partner to 
the Partnership shall not be considered a contribution of capital, shall not 
increase the Capital Account of the lending Partner or the lending Partner's 
ownership interest in the Partnership and the repayment of such loans by the 
Partnership shall not decrease, or result in any adjustment to, the Capital 
Account of the Partner making the loans;  no interest shall be paid on any 
capital contributed to the Partnership by any Partner;  under any 
circumstances requiring a return of all or any portion of a Capital 
Contribution, no Partner shall have the right to receive property other than 
cash; and  no Partner shall be required at any time to restore any deficit in 
such Partner's Capital Account.  

         4.3. No Third Party Beneficiary. No creditor or other third party 
having dealings with the Partnership shall have the right to enforce the 
right or obligation of any Partner to make Capital Contributions or loans or 
to pursue any other right or remedy hereunder or at law or in equity, it 
being understood and agreed that the provisions of this Agreement shall be 
solely for the benefit of, and may be enforced solely by, the parties hereto 
and their respective successors and assigns.  None of the rights or 
obligations of the Partners herein set forth to make Capital Contributions or 
loans to the Partnership shall be deemed an asset of the Partnership for any 
purpose by any creditor or other third party, nor may such rights or 
obligations be sold, transferred or assigned by the Partnership or pledged or 
encumbered by the Partnership to secure any debt or other obligation of the 
Partnership or of any of the Partners.

                                      ARTICLE V

                                   CAPITAL ACCOUNTS

         5.1. Establishment and Maintenance of Capital Accounts.  A Capital 
Account shall be established for each Partner in the amount of such Partner's 
Capital Contribution to the Partnership as reflected on Exhibit B attached 
hereto, as such Exhibit may be amended from time to time by the General 
Partner.  Unless otherwise provided in this Agreement, each Partner's Capital 
Account shall be determined and maintained in accordance with the rules of 
Treasury Regulation Section 1.704-1(b)(2)(iv) (or any corresponding provision 
of succeeding law), and all provisions of this Agreement relating to the 
maintenance of Capital Accounts shall be interpreted and applied in a manner 
consistent therewith.  If the General Partner shall determine that it is 
prudent to modify the manner in which the Capital Accounts, or any debits or 
credits thereto, are computed in order to comply with such regulations, the 
General Partner shall make such modifications. Pursuant to the foregoing 
accounting rules, a Partner's Capital Account shall be increased, decreased, 
adjusted, and maintained as provided in Article VII.

         5.2. Succession to Capital Accounts.  Subject to Section 11.4, in 
the event of a transfer of any Partnership Interest permitted herein, the 
Capital Account of the transferor Partner that is attributable to the 
transferred Partnership Interest shall be carried over to the transferee of 
such interest and adjusted as provided in the Regulations under Code section 
704.

         5.3. Certain Adjustments.  In connection with any Capital 
Contribution to the Partnership in consideration for a Partnership Interest, 
or a distribution by the Partnership to a Partner in respect of a Partnership 
Interest, the General Partner shall be authorized to increase or decrease the 
Capital Accounts to reflect a revaluation of Partnership property as provided 
in Regulation Section 1.704-1(b)(2)(iv)(f).

                                      ARTICLE VI

                                    DISTRIBUTIONS

         6.1. Distributions.  The General Partner shall cause the Partnership 
to distribute, on a quarterly or other basis as determined by the General 
Partner in its sole discretion, out of funds legally available therefor, such 
amount as the General Partner in its discretion shall determine, to the 
Partners of record as of the applicable Record Date, which distributions 
shall be made to the Partners pro rata based on the number of Units held by 
them as of such Record Date, subject to such preferential or subordinated 
distributions as may be required to be made by the Partnership on any 
additional class of Units that are hereafter created and that have a 
different right to share in partnership distributions than the GP Units and 
Class A Units.  Notwithstanding the foregoing, the General Partner reserves 
the right to pro-rate distributions to incoming Limited Partners who were 
admitted during the applicable quarter or such other period in which a

                                         -20-



distribution hereunder is to be made (but excluding any incoming Limited 
Partners who received Units from an existing Limited Partner) and who held 
Partnership Units as of the applicable Record Date but held such Partnership 
Units for less than the entire period with respect to which the distribution 
hereunder is to be made, such pro-ration to be based on the number of days 
such Units were outstanding during the applicable period or any other method 
of pro-ration deemed equitable by the General Partner.  In the event that 
pro-ration is made hereunder, the General Partner shall be authorized to 
adjust the amount of the distribution payable to all other Partners as the 
General Partner deems necessary.  In no event may a Partner receive a 
distribution with respect to a Unit if such Partner is entitled to receive a 
distribution with respect to a Common Share for which such Unit has been 
exchanged, and such distribution shall be made to the Company.

         6.2. Distributions upon Liquidation.  Liquidating distributions 
shall in all cases be made in accordance with the provisions of Section 13.5.

         6.3. Additional Distribution Rules.

              (a)  Effective Date.  Distributions shall be charged against 
the Partners' Capital Accounts as of the date the distributions are made.

              (b)  Division Among Limited Partners.  Except as may otherwise 
be provided herein or in the instruments creating a class of Partnership 
Interests, each distribution made to the Limited Partners of a given class 
pursuant to this Article VI shall be divided among the Limited Partners of 
such class so that each of them shall receive the same proportion thereof as 
the Units of such class owned by such Limited Partner bear to all Units of 
the same class then owned by all Limited Partners. 

              (c)  Obligation to Repay Distribution.  In the absence of fraud 
or mistake, or except as otherwise required by law, no Partner shall have any 
obligation or responsibility to repay to the Partnership any distribution 
made by the Partnership to a Partner pursuant to this Agreement.

              (d)  Legal Requirements.  Notwithstanding anything contained 
herein to the contrary, the General Partner may withhold making a 
distribution to any Limited Partner, or to any transferee of a Limited 
Partner, until the Limited Partner or the transferee has provided the General 
Partner with all necessary information and assurances, including an opinion 
of counsel satisfactory to the General Partner requested by the General 
Partner, to determine that such distribution will be in compliance with all 
applicable laws.

              (e)  Additional Distributions.  If the Partnership has taxable 
income for any Fiscal Year then the Partnership shall, out of any funds 
legally available therefor, distribute to the Partners, in the proportions 
described in Section 6.1, on or before the 90th day following the end of the 
calendar year that includes the last day of such Fiscal Year, the amount 
necessary 

                                         -21-


for the original holders of Class A Units issued on August 22, 1996 to pay 
federal, state and local income taxes with respect to such taxable income 
allocable to such Units, computed by multiplying such taxable income by the 
highest combined federal, state and local income tax rate applicable to any 
such Partner for the calendar year that includes the last day of the Fiscal 
Year in which such taxable income is allocated to such Partner.  The 
Partnership shall not make a distribution under this Section 6.3(e) if it 
does not have sufficient cash on hand to fund such distribution.

         6.4. Taxes Withheld.  Unless treated as a Tax Payment Loan (as 
hereinafter defined), any amount paid by the Partnership for or with respect 
to any Partner on account of any withholding tax or other tax payable with 
respect to the income, profits or distributions of the Partnership pursuant 
to the Code, the Regulations, or any state or local statute, regulation or 
ordinance requiring such payment (a "Withholding Tax Act") shall be treated 
as a distribution to such Partner for all purposes of this Agreement, 
consistent with the character or source of the income, profits or cash which 
gave rise to the payment or withholding obligation.  To the extent that the 
amount required to be remitted by the Partnership under a Withholding Tax Act 
exceeds the amount then otherwise distributable to such Partner, the excess 
shall constitute a loan from the Partnership to such Partner (a "Tax Payment 
Loan") which shall be payable upon demand and shall bear interest, from the 
date that the Partnership makes the payment to the relevant taxing authority, 
at the federal tax underpayment rate, under section 6621(a)(2) of the Code, 
as reported from time to time.  So long as any Tax Payment Loan or the 
interest thereon remains unpaid, the Partnership shall make future 
distributions due to such Partner under this Agreement by applying the amount 
of any such distribution first to the payment of any unpaid interest on all 
Tax Payment Loans of such Partner and then to the repayment of the principal 
of all Tax Payment Loans of such Partner.  The General Partner shall have the 
authority to take all actions necessary to enable the Partnership to comply 
with the provisions of any Withholding Tax Act applicable to the Partnership 
and to carry out the provisions of this Section.  Nothing in this Section 
shall create any obligation on the General Partner to advance funds to the 
Partnership or to borrow funds from third parties in order to make any 
payments on account of any liability of the Partnership under a Withholding 
Tax Act.

         6.5. In-Kind Distributions.  If, at the discretion of the General 
Partner, any assets of the Partnership other than cash are distributed to the 
Partners in kind, such assets shall be valued on the basis of the fair market 
value thereof as determined by the General Partner in its reasonable 
discretion on the date of distribution.  Without limiting the General 
Partner's discretion to make such a valuation or requiring that any such 
appraisal be made, the valuation of any asset by the General Partner on the 
basis of the determination of its fair market value by an independent 
appraiser shall be deemed to be a reasonable value for such asset and a 
reasonable exercise of such discretion.  If any Partnership property other 
than cash is distributed to a Partner, the Capital Accounts of the Partners 
shall be adjusted to reflect the manner in which the unrealized income, gain, 
loss or deduction inherent in such property (that has not previously been 
reflected in the Partners' Capital Accounts) would be allocated among the 
Partners if there had been a taxable disposition of such property at its fair 
market value on the date of distribution. 

                                         -22-



The Capital Accounts of the Partner receiving a distribution in kind shall 
then be reduced by the fair market value of the property distributed.  
Subject to the limitations on such distributions in connection with any 
distribution of property of the Partnership in kind, including any 
distribution in connection with the liquidation of the Partnership, the 
General Partner need not distribute each asset ratably to all Partners, so 
long as all Partners concurrently receive distributions of cash and other 
property, valued as provided above, in the proportion to which they would 
otherwise be entitled.

                                     ARTICLE VII

                                     ALLOCATIONS
                                           
         7.1. Allocation of Net Income and Net Loss.  After giving effect to 
the special allocations set forth in Section 7.2 hereof, Net Income or Net 
Loss shall be allocated among the Partners as follows:

              (a)  Net Income for any Fiscal Year shall be allocated first to 
the Partners until the cumulative amount of Net Income allocated pursuant to 
this Section 7.1(a) is equal to the cumulative amount of Net Loss allocated 
to the Partners pursuant to Section 7.1(b) hereof for all prior periods 
(without duplication) in reverse order to which prior Net Loss was allocated. 
Thereafter, Net Income shall be allocated to the Partners in accordance with 
their Percentage Interests.

              (b)  Net Loss for any Fiscal Year shall be allocated first, to 
the extent Net Income has been allocated pursuant to Section 7.1(a) hereof 
for any prior Fiscal Year (pro rata among the Partners in proportion to their 
share of the Net Income being offset); provided that to the extent any 
allocations of Net Income are offset pursuant to this Section, such 
allocations shall be disregarded for purposes of computing subsequent 
allocations pursuant to this Section 7.1(b).  Thereafter, Net Loss shall be 
allocated to the Partners in accordance with their Percentage Interests.

              (c)  Notwithstanding the provisions of Section 7.1(b), no 
amount of Net Loss shall be allocated to any Partner if such allocation would 
cause or increase a deficit balance in such Partner's Capital Account, after 
adjusting such Capital Account for the items described in Treasury 
Regulations Section 1.704-1(b)(2)(ii)(d)(4),(5), and (6) to the extent 
required therein and increasing such Capital Account by such Partner's share 
of Partnership Minimum Gain and Minimum Gain Attributable to Partner 
Nonrecourse Debt, if any.  Rather, such Net Loss shall be allocated to the 
General Partner and, to the extent Losses have been so allocated, then, 
notwithstanding Section 7.1(a), subsequent Net Income shall be allocated one 
hundred percent (100%) to the General Partner until the aggregate amount of 
Net Income allocated under this Section 7.1(c) for the current Fiscal Year 
and all previous Fiscal Years is equal to the aggregate amount of Net Loss 
allocated to the General Partner under this Section 7.1(c).

                                         -23-


         7.2. Special Allocations.  Notwithstanding anything to the contrary 
contained in this Agreement, the following allocations shall be made as 
applicable:

              (a)  Minimum Gain Chargeback (Nonrecourse Liabilities).  If 
there is a net decrease in Partnership Minimum Gain for any Partnership 
fiscal year (except as a result of conversion or refinancing of Partnership 
indebtedness, certain capital contributions or revaluation of the Partnership 
property as further outlined in Regulation Sections 1.704-2(d)(4), (f)(2) or 
(f)(3)), each Partner shall be specially allocated items of Partnership 
income and gain for each year (and, if necessary, subsequent years) in an 
amount equal to that Partner's share of the net decrease in Partnership 
Minimum Gain.  The items to be so allocated shall be determined in accordance 
with Regulation Section 1.704-2(g).  This paragraph (a) is intended to comply 
with the minimum gain chargeback requirement in said section of the 
Regulations and shall be interpreted consistently therewith.  Allocations 
pursuant to this paragraph (a) shall be made in proportion to the respective 
amounts required to be allocated to each Partner pursuant hereto.

              (b)  Minimum Gain Attributable to Partner Nonrecourse Debt.  If 
there is a net decrease in Minimum Gain Attributable to Partner Nonrecourse 
Debt during any fiscal year (other than due to the conversion, refinancing or 
other change in the debt instrument causing it to become partially or wholly 
nonrecourse, certain capital contributions, or certain revaluations of 
Partnership property as further outlined in Regulation Section 
1.704-2(i)(4)), each Partner shall be specially allocated items of 
Partnership income and gain for such year (and, if necessary, subsequent 
years) in an amount equal to that Partner's share of the net decrease in the 
Minimum Gain Attributable to Partner Nonrecourse Debt.  The items to be so 
allocated shall be determined in accordance with Regulation Section 
1.704-2(i)(4) and (j)(2).  This paragraph (b) is intended to comply with the 
minimum gain chargeback requirement with respect to Partner Nonrecourse Debt 
contained in said section of the Regulations and shall be interpreted 
consistently therewith. Allocations pursuant to this paragraph (b) shall be 
made in proportions to the respective amounts required to be allocated to 
each Partner pursuant hereto.

              (c)  Qualified Income Offset.  In the event a Partner receives 
any adjustments, allocations or distributions described in Regulation Section 
1.704-1(b)(2)(ii)(d)(4), (5) or (6), and such Partner has an Adjusted Capital 
Account Deficit, items of Partnership income and gain shall be specially 
allocated to such Partner in an amount and manner sufficient to eliminate the 
Adjusted Capital Account Deficit as quickly as possible.  This paragraph (c) 
is intended, among other things, to meet the requirements for a "qualified 
income offset" under Regulation Section 1.704-1(b)(2)(ii)(d) and shall be 
interpreted consistently therewith.

              (d)  Nonrecourse Deductions.  Nonrecourse Deductions for any 
fiscal year or other applicable period shall be allocated to the Partners in 
accordance with their respective Percentage Interests.

                                         -24-



              (e)  Partner Nonrecourse Deductions.  Partner Nonrecourse 
Deductions for any fiscal year or other applicable period shall be specially 
allocated to the Partner that bears the economic risk of loss for the debt 
(i.e., the Partner Nonrecourse Debt) in respect of which such Partner 
Nonrecourse Deductions are attributable (as determined under Regulation 
Section 1.704-2(b)(4) and (i)(1)).

              (f)  Curative Allocations.  The Regulatory Allocations shall be 
taken into account in allocating other items of income, gain, loss and 
deduction among the Partners so that, to the extent possible, the cumulative 
net amount of allocations of Partnership items under Sections 7.1 and 7.2 
shall be equal to the net amount that would have been allocated to each 
Partner if the Regulatory Allocations had not occurred.  This paragraph (f) 
is intended to minimize to the extent possible and to the extent necessary 
any economic distortions which may result from application of the Regulatory 
Allocations and shall be interpreted in a manner consistent therewith.  For 
purposes hereof, "Regulatory Allocations" shall mean the allocations provided 
under this Section 7.2 (save paragraphs (d) and (f) hereof).

         7.3. Tax Allocations.

              (a)  Generally.  Subject to paragraphs (b), (c) and (d) hereof, 
items of income, gain, loss, deduction and credit to be allocated for income 
tax purposes (collectively, "Tax Items") shall be allocated among the 
Partners on the same basis as their respective book items.

              (b)  Sections 1245/1250 Recapture.  If any portion of gain from 
the sale of property is treated as gain which is ordinary income by virtue of 
the application of Code Sections 1245 or 1250 ("Affected Gain"), then  such 
Affected Gain shall be allocated among the Partners in the same proportion 
that the depreciation and amortization deductions giving rise to the Affected 
Gain were allocated and  other Tax Items of gain of the same character that 
would have been recognized, but for the application of Code Sections 1245 
and/or 1250, shall be allocated away from those Partners who are allocated 
Affected Gain pursuant to clause (i) so that, to the extent possible, the 
other Partners are allocated the same amount, and type, of capital gain that 
would have been allocated to them had Code Sections 1245 and/or 1250 not 
applied.  For purposes hereof, in order to determine the proportionate 
allocations of depreciation and amortization deductions for each fiscal year 
or other applicable period, such deductions shall be deemed allocated on the 
same basis as Net Income and Net Loss for such respective period.

              (c)  Allocations Respecting Section 704(c) and Revaluations.  
Notwithstanding paragraph (b) hereof, Tax Items with respect to Partnership 
property that is subject to Code Section 704(c) and/or Regulation Section 
1.704-1(b)(2)(iv)(f) (collectively "Section 704(c) Tax Items") shall be 
allocated in accordance with said Code section and/or Regulation Section 
1.704-1(b)(4)(i), as the case may be.  The Partnership shall apply the 
"traditional method" for such allocations, as described in Regulation Section 
1.704-3(b), and the 

                                         -25-


allocation of Tax Items shall be subject to the ceiling rule stated in 
Regulation Section 1.704-3(b)(1). 

              (d)  Pre-contribution Gain.  In the event that, during any 
fiscal year or other applicable period, any Title Holding Partnership 
allocates to the Partnership Pre-contribution Gain (as defined below), each 
Partner (or its successors in interest) who, pursuant to Article IV hereof, 
contributed to the capital of the Partnership the Contributed Asset to which 
a distributive share of Pre-contribution Gain is attributable shall be 
allocated that Pre-contribution Gain in accordance with its respective 
interest in such Pre-contributed Gain. For purposes hereof, "Pre-contribution 
Gain" shall mean, with respect to each Property owned by a Title Holding 
Partnership, that unrealized gain attributable to the excess of  the fair 
market value of such Property on the date at which the Contributed Asset is 
contributed to the capital of the Partnership pursuant to Article IV hereof, 
over  the adjusted tax basis of such Property on the date of such 
contribution; provided, however, that the amount of any Pre-contribution Gain 
associated with a Property shall be adjusted to account for allocations made 
in accordance with the provisions of paragraph (c) of this Section 7.3 and 
shall not, in any event, exceed that amount of gain actually allocated to the 
Partnership by a Title Holding Partnership as a result of the sale or other 
disposition of such Property.

              (a)  Do any act in contravention of this Agreement;

              (b)  Possess any Partnership property or assign rights in 
specific Partnership property for other than Partnership purposes; 

              (c)  Do any act in contravention of applicable law; or

              (d)  Without the consent of the holders of at least fifty

relief for the Partnership under any provision of the federal Bankruptcy Code 
11 U.S.C. Section 101 et seq. or any other federal or state law relating to 
insolvency, bankruptcy or reorganization.

         Nothing herein contained shall impose any obligation on any Person 
or firm doing business with the Partnership to inquire as to whether or not 
the General Partner has properly exercised its authority in executing any 
contract, lease, mortgage, deed or other instrument on behalf of the 
Partnership, and any such third Person shall be fully protected in relying 
upon such authority.

         8.5. Compensation of the General Partner.  The General Partner shall 
not be entitled to any compensation for services rendered to the Partnership

entitled under this Agreement.

         8.6. Waiver and Indemnification.

              (a)  Except as otherwise provided in Article XVIII, neither the 
General Partner nor any Person acting on its behalf, pursuant hereto, shall 
be liable, responsible or accountable in damages or otherwise to the 
Partnership or to any Partner for any acts or omissions performed or omitted 
to be performed by it within the scope of the authority conferred upon the 
General Partner by this Agreement and the Act, provided that the General 
Partner's or such other Person's conduct or omission to act was taken in good 
faith and in the belief that such conduct or omission was in the best 
interests of the Partnership and, provided further, that the General Partner 
or such other Person shall not be guilty of fraud, willful misconduct or 
gross negligence as determined by a court of competent jurisdiction.  

                                         -31-


              (b)  The Partnership shall, and hereby does, indemnify and hold 
harmless the General Partner and its Affiliates and any individual acting on 
their behalf from any loss, cost or expense, damage, claim or liability, 
including, but not limited to, reasonable attorneys' fees and expenses, 
incurred by them by reason of any act performed by them for or on behalf of 
the Partnership or the General Partner, or omitted to be performed by them, 
in accordance with the standards set forth above or in enforcing the 
provisions of this indemnity; provided, however, no Partner or any of its 
Affiliates shall have any personal liability with respect to the foregoing 
indemnification, and any such liability or indemnification shall be satisfied 
solely out of the assets of the Partnership.  

              (c)  All rights of any indemnitee hereunder shall survive the

remedies and recourse to which the person seeking indemnification shall be 
entitled, whether at law or at equity.

         8.7. Operation in Accordance with REIT Requirements.  The Partners 
acknowledge and agree that the Partnership shall be operated in a manner that 
will enable the General Partner to (a) satisfy the REIT Requirements and (b) 
avoid the imposition of any federal income or excise tax liability on either 
the General Partner or the Partnership.  Notwithstanding any provision of 
this Agreement, the General Partner shall not be required to take any action 
which would result in the General Partner ceasing to satisfy the REIT 
Requirements or the imposition of any federal income or excise tax liability 
on the General Partner.  

         8.8. Reliance by Third Parties.  

              (a)  Notwithstanding anything to the contrary in this 
Agreement, any Person dealing with the Partnership shall be entitled to 
assume that the General Partner has full power and authority to encumber, 
sell or otherwise use in any manner any and all assets of the Partnership and 
to enter into any contracts on behalf of the Partnership, and such Person 
shall be entitled to deal with the General Partner as if it were the 
Partnership's sole party in interest, both legally and beneficially.  

              (b)  Each Limited Partner hereby waives any and all defenses or 
other remedies which may be available against such Person to contest, negate 
or disaffirm any action of the General Partner in connection with any such 
dealing.  In no event shall any Person dealing with the General Partner or 
its representatives be obligated to ascertain that the terms of this 
Agreement have been complied with or to inquire into the necessity or 
expedience of any act or action of the General Partner or its 
representatives.  Each and every certificate, document or other instrument 
executed on behalf of the Partnership by the General Partner shall be 
conclusive evidence in favor of any and every person relying thereon or 
claiming thereunder that (i) at the time of the execution and delivery of 
such certificate, document or instrument, this Agreement 

                                         -32-


was in full force and effect, (ii) the Person executing and delivering such 
certificate, document or instrument was duly authorized and empowered to do 
so for and on behalf of the Partnership, and (iii) such certificate, document 
or instrument was duly executed and delivered in accordance with the terms 
and provisions of this Agreement and is binding upon the Partnership.

         8.9. Other Matters Concerning the General Partner.

              (a)  The General Partner may rely and shall be protected in 
acting or refraining from acting upon any resolution, certificate, statement, 
instrument, opinion, report, or other document believed by it to be genuine 
and to have been singed or presented by the proper party or parties.

              (b)  The General Partner may consult with legal counsel, 
accountants, appraisers, management consultants, investment bankers and other 
consultants and advisers selected by it, and any act taken or omitted to be 
taken in reliance upon the opinion of such Persons as to matters which such 
General Partner reasonably believes to be within such Person's professional 
expertise shall be conclusively presumed to have been done or omitted in good 
faith and in accordance with such opinion.

              (c)  The General Partner shall have the right, in respect of 
any of its powers or obligations hereunder, to act through any of its duly 
authorized officers and any attorney or attorneys-in-fact duly appointed by 
the General Partner; and any Person dealing with the Partnership shall be 
entitled to rely on any certificate, document or other instrument executed on 
behalf of the Partnership by a duly authorized officer or by a duly 
authorized attorney or attorneys-in-fact of the General Partner.  Each such 
attorney-in-fact shall, to the extent provided by the General Partner in the 
power of attorney, have full power and authority to do and perform all and 
every act and duty which is permitted or required to be done by the General 
Partner hereunder.

              (d)  Notwithstanding any other provisions of this Agreement or 
the Act, any action of the General Partner on behalf of the Partnership or 
any decision of the General Partner to refrain from acting on behalf of the 
Partnership, undertaken in the good faith belief that such action or omission 
is necessary or advisable in order (i) to protect or further the ability of 
the General Partner to continue to qualify as a REIT or (ii) to avoid the 
General Partner incurring any taxes under Section 857 or Section 4981 of the 
Code, is expressly authorized under this Agreement and is deemed approved by 
all of the Limited Partners.  Nothing however in this Agreement shall be 
deemed to give rise to any liability on the part of the Limited Partners for 
the General Partner's failure to qualify or continue to qualify as a REIT or 
failure to avoid incurring any taxes under the foregoing Sections of the Code.

                                         -33-


         8.10.     Meetings of Partners.

              (a)  Meetings of Partners may be called at any time by the 
General Partner to consider, and shall be so called so that the Partners may 
act on, any matter on which they are entitled to act under the terms of this 
Agreement or the Act.  In addition, the General Partner shall call a meeting 
of Class A Limited Partners when directed to do so by holders of not less 
than twenty-five percent (25%) of the then outstanding Class A Units.  Such 
direction shall be given by delivering to the General Partner a request in 
writing stating that such holders desire to call a meeting and indicating the 
general or specific purpose for which the meeting is to be called.  

              (b)  The General Partner may fix a date not more than sixty 
(60) nor less than five (5) days preceding the date of any meeting of 
Partners, or preceding the last day on which the consent of Partners may be 
effectively expressed for any purpose without a meeting, as a record date for 
the determination of the Partners entitled to notice of, and to vote at, such 
meeting or to express such consent.  In either such case, such Partners, and 
only such Partners as shall be Partners of record on the Record Date shall be 
entitled to notice of, and to vote at, such meeting and any adjournment 
thereof, or to express such consent, as the case may be, notwithstanding any 
transfer of any Partnership Interest on the Register after any such Record 
Date fixed as aforesaid.

              (c)  Notice of any meeting at which Partners are entitled to 
vote, or of any matter upon which action by written consent of such Partners 
is to be taken, shall be given to each Partner of record not less than five 
(5) nor more than sixty (60) days prior to the date of such meeting or the 
date on which consent must be given, as the case may be.  Each such notice 
will include a statement setting forth (i) the date, time and place of the 
meeting or the date by which such action is to be taken, (ii) a description 
of the matter on which such Partners are entitled to vote or of such matter 
upon which written consent is sought and (iii) instructions for the delivery 
of proxies or consents.

              (d)  Except as otherwise provided by law, at any meeting of 
Partners, the holders of a majority of the Units entitled to vote as such 
meeting shall constitute a quorum at such meeting.  In the absence of a 
quorum, the holders of a majority of the Units entitled to vote thereat 
present in person or by proxy may adjourn any meeting, from time to time, 
until a quorum shall be present.  At any such adjourned meeting at which a 
quorum shall be present, any business may be transacted which might have been 
transacted at the meeting as originally called.

              (e)  Each Partner entitled to vote at a meeting or entitled to 
express consent to Partnership action in writing without a meeting may 
authorize another person or persons to act for him by proxy.  A proxy acting 
for any Partner shall be duly appointed by an instrument in writing 
subscribed by such Partner and reasonably acceptable in form and substances 
to the General Partner.  Except as otherwise provided by law, no vote on any 
question upon which a vote of the Partners may be taken need be by ballot 
unless the General Partner shall 

                                         -34-


determine that it shall be by ballot or the holders of a majority of all 
Units  present in person or by proxy and entitled to participate in such vote 
shall so demand.  In a vote by ballot each ballot shall state the Partnership 
Interests voted and the name of the Partner or proxy voting. Unless otherwise 
provided by law or by this Agreement, all questions shall be decided by the 
vote of the holders of a majority of the Units present in person or by proxy 
at the meeting and entitled to vote on the question.

              (f)  Any action required to or which may be taken at a meeting 
of Partners may be taken without a meeting, without prior notice and without 
a vote, if a consent or consents in writing, setting forth the action so 
taken, shall be signed by Partners having not less than the minimum number of 
votes that would be necessary to authorize such action at a meeting at which 
all Units entitled to vote thereon were present and voted, and shall be 
delivered to the Partnership by delivery to the General Partner (who shall 
have custody of the books in which proceedings of meetings of Partners are 
recorded).  Prompt notice of the taking of action without a meeting shall be 
given to the Partners entitled to vote who have not consented in writing.

              (g)  The General Partner, in its sole discretion, shall 
establish all other provisions relating to meetings of Partners, in addition 
to those expressly provided herein, including notice of the time, place or 
purpose of any meeting at which any matter is to be voted on by any Partner, 
waiver of any such notice, action by consent without a meeting, the 
establishment of a record date, quorum requirements, voting in person or by 
proxy or any other matter with respect to the exercise of any such right to 
vote, in each case consistent with the terms hereof and in accordance with 
the Act.

credits and deductions for the immediately preceding Fiscal Year, together 
with all other information concerning the Partnership which may be required 
by the Code from time to time.

within 120 days after the end of each Fiscal Year Audited Financial

amendments thereto, together with executed copies of all powers of attorney 
pursuant to which this Agreement, the Certificate and all amendments thereto 
have been executed.

              (c)  Notwithstanding any other provision of this Section 9.2, 
the General Partner may keep confidential from the Limited Partners, for such 
period of time as the General Partner determines in its sole discretion to be 
reasonable, any information that (i) the General Partner reasonably believes 
to be in the nature of trade secrets or other information the disclosure of 
which the General Partner in good faith believes is not in the best interests 
of the Partnership or could damage the Partnership or its business, or (ii) 
the Partnership is required by law or by agreements with an unaffiliated 
third party to keep confidential.

         9.3. Tax Returns.  The General Partner shall cause all income and 
other tax returns of the Partnership to be prepared and filed in a timely

time designate. Funds in such accounts shall not be commingled with the funds 
of any Partner.

                             CHANGES IN GENERAL PARTNERS

         10.1.     Permitted Assignment of General Partnership Interest.  The 
General Partner shall not have the right to resign or withdraw or to Transfer 
all or any portion of its General Partnership Interest represented by GP 
Units, except that the General Partner may (a) assign all or a portion of its 
General Partnership Interest represented by outstanding GP Units to a 
substitute or additional General Partner permitted under Section 10.2; (b) 
assign its General Partnership Interest represented by outstanding GP Units 
to any Entity that has acquired, or in connection with such assignment will 
acquire, by merger, consolidation or otherwise, substantially all of its 
assets or equity interests and has been designated to succeed to its rights 
and obligations under this Agreement in accordance herewith; and (c) pledge 
or grant a security interest in its right to receive payments and 
distributions under this Agreement.  In connection with any Transfer 
described in clauses (a) and (b) of all the General Partnership Interest, the 
General Partner may withdraw as such upon the admission of the assignee.  
Sections 10.2 and 10.4 shall apply in the case of a Transfer of all or a 
portion of a General Partnership Interest.

         10.2.     Admission of Additional General Partners.  One or more 
additional or substitute General Partners may be admitted to the Partnership 
from time to time by the General Partner in the circumstances contemplated by 
Section 10.1, provided the additional or substitute general partner is 
reasonably expected, as determined by a majority of the Board of Trustees of 
BRT, to be able to fulfill the duties of a general partner hereunder.  
Otherwise, no additional General Partner may be admitted to the Partnership 
except as provided in Section 13.2.  The terms of such assignment and the 
nature of the duties of the newly admitted General Partner shall be as agreed 
upon between the General Partner and such additional General Partner.

         10.3.     Effect of Withdrawal of General Partner.  

              (a)  Upon the occurrence of an Event of Withdrawal of the 
General Partner (other than one permitted by Section 10.1), the General 
Partner shall cease to be such, and its General Partnership Interest shall be 
converted to an undesignated Limited Partnership Interest entitling the 
holder thereof to the same share of the Partnership's income, gain, loss, 
deduction and distributions as are allocated to the General Partner 
hereunder, subject to the Partnership's right to set off (i) any damages 
caused to the Partnership if the Event of Withdrawal is in violation of this 
Agreement and (ii) any obligation of the General Partner under paragraph (b).

              (b)  Upon the occurrence of an Event of Withdrawal of the 
General Partner, the General Partner shall pay to the Partnership in cash the 
amount of any deficit balance in its Capital Account unless the Event of 
Withdrawal is permitted by Section 10.1.

                                         -37-


         10.4.     Liability of a Withdrawn General Partner.  Any General 
Partner who shall commit or suffer an Event of Withdrawal or shall otherwise 
withdraw from the Partnership shall remain liable for obligations and 
liabilities incurred by it as General Partner prior to the occurrence of such

obligation or liability incurred on account of the activities of the 
Partnership thereafter.

                      TRANSFERS OF LIMITED PARTNERSHIP INTERESTS

         11.1.     General Transfer Provisions and Restrictions.

              (a)  Subject to the restrictions set forth in this Section 
11.1, any Limited Partner may Transfer all or any portion of, or right in or 
to, his or its Limited Partnership Interest, without the consent of the 
General Partner or any other Partner, except that no Limited Partner may 
Transfer Class A Units comprising Collateral in violation of the provisions 
of Article XVIII below.

              (b)  Notwithstanding the foregoing,

                   (i)  No Transfer of any Limited Partnership Interest shall 
be permitted if, in the opinion of the General Partner based on the advice of 
counsel, there is a significant possibility that such Transfer:

                        (A)  may not be effected without registration under 
the Securities Act of 1933, or would result in the violation of any 
applicable state securities laws; or

                        (B)  would result in the termination of the 
Partnership within the meaning of section 708 of the Code, or would have a 
material adverse effect on any Partner for federal income tax purposes; or

                        (C)  would cause the Partnership to be taxed other 
than as a partnership for federal income tax purposes or impair the ability 
of the Partnership to take advantage of any favorable tax election or 
treatment as a result of being taxed as a partnership (whether such 
impairment shall arise from the termination of the Partnership for federal 
tax purposes or otherwise); or

                        (D)  would cause the Partnership to become, with 
respect to any employee benefit plan subject to Title 1 of ERISA, a 
"party-in-interest" (as defined in Section 3(14) of ERISA) or a "disqualified 
person" (as defined in Section 4975(c) of the Code); or


                                      -38-



                        (E)  would cause any portion of the assets of the 
Partnership to constitute assets of any employee benefit plan pursuant to 
Department of Labor Regulations Section 2510.2-101; and

                   (ii) No Limited Partner shall effect any Transfer:

                        (A)  to any person or entity who lacks the legal 
right, power or capacity to own Partnership Units;

                        (B)  in violation of any provision of any mortgage or 
trust deed (or the note or bond secured thereby) to which the Partnership is 
a party or is otherwise bound;

                        (C)  of any component portion of Partnership Units, 
such as the Capital Account, or rights to distribution, separate and apart 
from all other components of Partnership Units; or

                        (D)  in the event such Transfer would cause BRT or 
any successor thereto to cease to comply with the REIT Requirements.

                                         -38-

         In furtherance of this subsection, the General Partner and the 
Partnership shall in no event recognize any trade of a Limited Partnership 
Interest in a secondary market or the substantial equivalent thereof and 
shall take such actions as are necessary so that such trades are not 
recognized.

              (c)  All Transfers of Limited Partnership Interests shall be by 
instrument in form and substance reasonably satisfactory to the General 
Partner.  Any Transfer of Limited Partnership Interests in violation of this 
Agreement shall be null and void ab initio and shall not operate to vest any 
rights in any transferee.

              (d)  In no event shall the Partnership dissolve or terminate 
upon the admission of any Partner to the Partnership or upon any permitted 
Transfer of a Partnership Interest by any Partner.  Each Partner hereby 
waives its right to dissolve, liquidate or terminate the Partnership in such 
event.  No Transfer of any Limited Partnership Interest in the Partnership 
shall constitute a change of Control of the Partnership.

         11.2.     Expenses.  All expenses of the Partnership and of the 
Partners occasioned by a Transfer permitted under Section 11.1 shall be borne 
by the Partner effecting such Transfer.

                                         -39-


         11.3.     Allocations with Respect to Transferred Interest.  Upon 
the permitted Transfer of all or any part of a Partnership Interest, each 
item of Partnership income (or loss) and deduction allocable to such 
Partnership Interest shall be pro rated (as to the Transferred Partnership 
Interest) between the transferor and transferee on the basis of the number of 
days in the taxable year of the Partnership preceding (and including) and 
succeeding, respectively, the date as of which the assignment is executed.  
Unless otherwise agreed by the Transferor and Transferee Partners and written 
notice of such agreement has been given to the General Partner, gain or loss 
from the sale or other taxable disposition of a Partnership capital asset 
shall be allocated to the Persons who were Partners at the time such gain or 
loss was recognized by the Partnership.

         11.4.     Section 754 Election.  The General Partner may, in its 
sole discretion, cause the Partnership to elect, pursuant to section 754 of 
the Code, to adjust the basis of Partnership property as provided in sections 
734(b) and 743(b) of the Code.  The General Partner shall be responsible for 
determining the adjustments required or permitted by said sections of the 
Code, except that, in the case of any adjustment required or permitted under 
section 743(b) of the Code, the Transferee Partner or Partners shall be 
solely responsible for determining the adjustments required thereunder unless 
such Partner or Partners provide the General Partner with all the information 
necessary for the General Partner to determine the adjustments.  If any 
adjustments to the basis of Partnership property are made pursuant to section 
732(d), 734(b) or 743(b), the capital accounts of the Partners shall be 
adjusted as specified in Regulation Section 1.704-1(b)(2)(iv)(m).

         11.5.     Transferee's Rights.  The Transfer of a Limited 
Partnership Interest in accordance with this Agreement entitles the 
transferee, subject to Section 11.3, to share in such profits and losses, to 
receive such distributions, and to receive such allocations of income, gain, 
loss, deduction, or credit or similar item to which the transferor Partner 
was entitled (to the extent of the interest Transferred) but does not entitle 
the transferee to become or to exercise any other rights of a Partner unless 
and until the transferor Partner has advised the General Partner that such 
transferor Partner is to be admitted as a Partner pursuant to Article XII.

                                     ARTICLE XII

                                ADMISSION OF PARTNERS

         12.1.     Procedure.  Substitute or additional General or Limited 
Partners may be admitted to the Partnership as a result of a permitted 
Transfer of Partnership Interests pursuant to Article X or XI.  Additional 
General or Limited Partners shall also be admitted to the Partnership as a 
result of the issuance of additional Partnership Interests pursuant to 
Article III.  Each substitute or additional Partner shall sign a supplement 
to this Agreement at the time such Partner is admitted confirming the 
admission of the new Partner hereunder, and containing such Person's binding 
agreement to be bound by all of the terms of this Agreement.

                                         -40-


         12.2.     Admission.    In connection with the admission of any new 
Partner to the Partnership, the General Partner shall have the power, right 
and authority to amend this Agreement and any applicable Exhibit or Schedule 
hereto to reflect the rights and obligations of such new Partner, including 
without limitation its obligations to contribute to the capital of the 
Partnership, rights to distributions, and rights to approve or consent to 
Partnership actions.

                                     ARTICLE XIII

                       DISSOLUTION, LIQUIDATION AND WINDING-UP

         13.1.     Events of Dissolution.  The occurrence of any of the 
following shall constitute an event of dissolution of the Partnership (an 
"Event of Dissolution"):

              (a)  the expiration of the term of the Partnership as provided 
in Section 2.5;

              (b)  the sale or other disposition in a single transaction or 
series of related transactions of all or substantially all of the assets of 
the Partnership unless such sale or other disposition involves any deferred 
payment of the consideration for such sale or disposition, in which case the 
General Partner may elect to defer the dissolution of the Partnership until 
the last day of the Fiscal Year during which the Partnership shall receive 
the balance of such deferred payment;

              (c)  subject to Section 13.2, the occurrence of an Event of 
Withdrawal with respect to a General Partner; 

              (d)  the acquisition by a single Person of all of the 
Partnership Interests;

              (e)  the issuance of a decree of dissolution by a court of 
competent jurisdiction pursuant to the Act; or

              (f)  the consent of the General Partner and the holders of at 
least  a majority of the then outstanding Class A Units.

         13.2.     Continuation of the Business of the Partnership After 
Dissolution.

              (a)  Notwithstanding Section 13.1(c), if, at the time of an 
Event of Withdrawal, there shall be one or more General Partners not affected 
by the Event of Withdrawal, then such other General Partner or General 
Partners shall (and are hereby authorized to) carry on the business of the 
Partnership, and if they do so, the Partnership shall not be liquidated and 
its business wound up.

                                         -41-


              (b)  Notwithstanding Section 13.1(c), at the time of an Event 
of Withdrawal to which subsection (a) is not applicable, the Partnership 
shall not be liquidated and its business wound up if, within 90 days after 
the occurrence of the Event of Withdrawal, Limited Partners owning a majority 
of the Units of each class then outstanding agree in writing to continue the 
business of the Partnership and to the appointment of one or more replacement 
General Partners who agree to serve as such.

         13.3.     Effect of Event of Dissolution.  Upon the occurrence of an 
Event of Dissolution, unless otherwise provided in Section 13.2, the 
Partnership shall be dissolved and shall continue solely for the purposes of 
winding up its business and liquidating in accordance with this Article XIII 
all of its assets and collecting the proceeds from such liquidation, at which 
time the Partnership shall be wound up.  Unless the business of the 
Partnership is continued as provided in Section 13.2, after the occurrence of 
an Event of Dissolution, the Partnership shall engage in no further business 
other than as necessary to operate on an interim basis and for the 
Partnership to collect its receivables, liquidate its assets and pay or 
discharge its liabilities in accordance with this Article XIII. 

         13.4.     Accounting.  In the event of the dissolution, liquidation 
and winding-up of the Partnership, a proper accounting (which shall be 
certified) shall be made of the Capital Account of each Partner and of the 
Net Income or Net Losses of the Partnership from the date of the last 
previous accounting to the date of dissolution.  Financial statements 
presenting such accounting shall include a report thereon of a certified 
public accountant selected by the Liquidating Trustee.

         13.5.     Distribution on Dissolution.

              (a)  In the event of the dissolution and liquidation of the 
Partnership for any reason, the assets of the Partnership shall be liquidated 
for distribution and distributed in the following rank and order:

                   (i)  First, for payment of creditors of the Partnership 
(other than Partners) in the order of priority as provided by law;

                   (ii) Next, for establishment of reserves as provided by 
the Liquidating Trustee to provide for contingent liabilities, if any;

                   (iii)     Next, for payment of debts of the Partnership to 
Partners, if any, in the order of priority provided by law; and

                   (iv) Last, for payment to the General Partner and to the 
holders of the Class A Units, in accordance with the positive balances in 
their respective Capital Accounts after giving effect to all contributions, 
distributions and allocations for all periods, 

                                         -42-



including the period in which such distribution occurs (other than those 
adjustments made pursuant to this Section 13.5(a)(iv)).

              (b)  Whenever the Liquidating Trustee reasonably determines 
that any reserves established pursuant to paragraph (a)(ii) above are in 
excess of the reasonable requirements of the Partnership, the amount 
determined to be excess shall be distributed to the Partners in accordance 
with the above provisions.

         13.6.     Timing Requirements.  In the event that the Partnership is 
"liquidated" within the meaning of Section 1.704-1(b)(2)(ii)(g) of the 
Regulations, any and all distributions to the Partners pursuant to Section 
13.5(a) hereof shall be made no later than the later to occur of (i) the last 
day of the taxable year of the Partnership in which such liquidation occurs, 
or (ii) ninety (90) days after the date of such liquidation.

         13.7.     Sale of Partnership Assets.  In the event of the 
liquidation of the Partnership in accordance with the terms of this 
Agreement, the Liquidating Trustee may sell Partnership or Title Holding 
Partnership property if the Liquidating Trustee has in good faith solicited 
bids from unrelated third parties before making any such sale; provided, 
however, all sales, leases, encumbrances or transfers of Partnership assets 
shall be made by the Liquidating Trustee solely on an "arm's-length" basis, 
at the best price and on the best terms and conditions as the Liquidating 
Trustee in good faith believes are reasonably available at the time and under 
the circumstances and on a non-recourse basis to the Limited Partners.  The 
liquidation of the Partnership shall not be deemed finally completed until 
the Partnership shall have received cash payments in full with respect to 
obligations such as notes, installment sale contracts or other similar 
receivables received by the Partnership in connection with the sale of 
Partnership assets and all obligations of the Partnership have been 
satisfied, released or assumed by the General Partner.  The Liquidating 
Trustee shall continue to act to enforce all of the rights of the Partnership 
pursuant to any such obligations until such obligations are paid in full or 
otherwise satisfied.

         13.8.     Distributions in Kind.  In the event that it becomes 
necessary to make a distribution of Partnership property in kind, the 
Liquidating Trustee may transfer and convey such property to the distributees 
as tenants in common, subject to any liabilities attached thereto, so as to 
vest in them undivided interests in the whole of such property in proportion 
to their respective rights to share in the proceeds of the sale of such 
property (other than as a creditor) in accordance with the provisions of 
Section 13.5 hereof.

         13.9.     Documentation of Liquidation.  Upon the completion of the 
dissolution and liquidation of the Partnership, the Partnership shall 
terminate and the Liquidating Trustee shall have the authority to execute and 
record any and all documents or instruments required to effect the 
dissolution, liquidation and termination of the Partnership.

                                         -43-


         13.10.    Liability of the Liquidating Trustee.  The Liquidating 
Trustee shall be indemnified and held harmless by the Partnership from and 
against any and all claims, demands, liabilities, costs, damages and causes 
of action of any nature whatsoever arising out of or incidental to the 
Liquidating Trustee's taking of any action authorized under or within the 
scope of this Agreement; provided, however, that the Liquidating Trustee 
shall not be entitled to indemnification, and shall not be held harmless, 
where the claim, demand, liability, cost, damage or cause of action at issue 
arose out of (a) a matter entirely unrelated to the Liquidating Trustee's 
action or conduct pursuant to the provisions of this Agreement; or (b) the 
willful misconduct or gross negligence of the Liquidating Trustee.

                                     ARTICLE XIV

                    RIGHTS AND OBLIGATIONS OF THE LIMITED PARTNERS

         14.1.     No Participation in Management.  The Limited Partners 
shall not take part in the management or control of the Partnership's 
business, transact any business in the Partnership's name, have the power to 
sign documents for or otherwise bind the Partnership or except as required by 
the Act or expressly provided by this Agreement, have any right to vote on or 
consent to any matter, provided, however, that nothing in the foregoing shall 
be deemed to prohibit or preclude any Limited Partner or its Affiliates from 
serving as an officer, trustee, director or employee of the General Partner 
or its Affiliates or otherwise transacting business with the Partnership.

         14.2.     Death, Incompetence, Bankruptcy, Etc.  The death, 
incompetence, Bankruptcy, dissolution or liquidation of a Limited Partner 
shall not cause a dissolution of the Partnership. The rights of such a 
Limited Partner to share in the income and losses of the Partnership, to 
receive distributions and to assign its Partnership Interest pursuant to this 
Article, on the happening of such an event, shall devolve on such Limited 
Partner's beneficiary or other successor, executor, administrator, guardian 
or other legal representative for the purpose of settling the estate or 
administering the property of such Limited Partner.  Such successor or 
personal representative, however, shall be admitted as a Limited Partner only 
upon compliance with the requirements set forth in Article XII.

         14.3.     No Withdrawal.  No Limited Partner may withdraw from the 
Partnership without the prior written consent of the General Partner, other 
than as expressly provided in this Agreement.

         14.4.     Power of Attorney.  Each Limited Partner constitutes and 
appoints the General Partner, any Liquidating Trustee, and authorized 
officers and attorneys-in-fact of each, and each of those acting singly, in 
each case with full power of substitution, as its true and lawful agent and 
attorney-in-fact, with full power and authority in its name, place and stead 
to:  execute, swear to, acknowledge, deliver, file and record in the 
appropriate public offices (i) all certificates, documents 

                                         -44-



and other instruments (including, without limitation, this Agreement and the 
Certificate and all amendments or restatements thereof) that the General 
Partner or the Liquidating Trustee deems appropriate or necessary to form, 
qualify or continue the existence or qualification of the Partnership as a 
limited partnership (or a partnership in which the limited partners have 
limited liability) in the State of Delaware and in all other jurisdictions in 
which the Partnership may conduct business or own property; (ii) all 
instruments that the General Partner deems appropriate or necessary to 
reflect any amendment, change, modification or restatement of this Agreement 
in accordance with its terms; (iii) all conveyances and other instruments or 
documents that the General Partner deems appropriate or necessary to reflect 
the dissolution and liquidation of the Partnership pursuant to the terms of 
this Agreement, including, without limitation, a certificate of cancellation; 
and (iv) all instruments relating to the admission, withdrawal, removal or 
substitution of any Partner pursuant to the provisions of this Agreement, or 
the Capital Contribution of any Partner.  The foregoing power of attorney is 
irrevocable and a power coupled with an interest, in recognition of the fact 
that each of the Partners will be relying upon the power of the General 
Partner to act as contemplated by this Agreement in any filing or other 
action by it on behalf of the Partnership, and it shall survive the death, 
incapacity or incompetency of a Limited Partner to the effect and extent 
permitted by law and the Transfer of all or any portion of such Limited 
Partner's Partnership Units and shall extend to such Limited Partner's heirs, 
distributees, successors, assigns and personal representatives.

         14.5.     Limited Liability of Limited Partners.  The Limited 
Partners shall not be personally liable for any obligations or debts of the 
Partnership to third parties, except to the extent provided in the Act.

                    GRANT OF REDEMPTION RIGHTS TO LIMITED PARTNERS

         15.1.     Grant of Redemption Rights.  

              (a)  The Partnership does hereby grant to each Limited Partner 
owning Class A Units and each such Limited Partner does hereby accept the 
right, but not the obligation (hereinafter such right sometimes referred to 
as the "Redemption Right"), to require the Partnership to redeem, for cash, 
on the Specified Redemption Date all or any portion of the Class A Units held 
by such Limited Partner at a redemption price equal to the Cash Amount.  The 
Redemption Right of a Limited Partner may be exercised on one or more 
occasions by the Limited Partner.  The Redemption Right shall be exercised 
pursuant to a Notice of Redemption delivered to the Partnership (with a copy 
to the General Partner) by the Limited Partner (the "Redeeming Partner") who 
is exercising the Redemption Right.  A Limited Partner may not exercise the 
Redemption Right as to fewer Class A Units than the number of such Units that 
is equal to the lesser of (a) 100 Units or (b) all of the Class A Units held 
by such Limited Partner.  Neither the Redeeming Partner nor any assignee of 
any Limited Partner shall have any right with respect to any Class A Units so 
redeemed to receive any distributions from the Partnership made after the 
Specified Redemption Date.  The 

                                         -45-


assignee of any Limited Partner may exercise the rights of such Limited 
Partner pursuant to this Section 15.1, and such Limited Partner shall be 
deemed to have assigned such rights to such assignee and shall be bound by 
the exercise of such rights by such Limited Partner's assignee.  In 
connection with any exercise of such rights by such assignee on behalf of 
such Limited Partner, the Cash Amount shall be paid by the Partnership 
directly to such assignee and not to such Limited Partner.

              (b)  The General Partner may, in connection with the issuance 
by the Partnership of additional Class A Units, impose restrictions on the 
exercise by the Limited Partners owning such Class A Units of the Redemption 
Right for such period of time as the General Partner may designate.

         15.2.     General Partner Exchange.

              (a)  Notwithstanding the provisions of Section 15.1, if a 
Limited Partner elects to exercise the Redemption Right, the General Partner 
may, in its sole and absolute discretion, elect to assume directly and 
satisfy a Redemption Right by paying to the Redeeming Partner either the Cash 
Amount or the GP Shares Amount for each Class A Unit redeemed, as elected by 
the General Partner (in its sole and absolute discretion) on the Specified 
Redemption Date, whereupon the General Partner shall acquire the Class A 
Units offered for redemption by the Redeeming Partner and shall be treated 
for all purposes of this Agreement as the owner of such Partnership Interests.

              (b)  In the event that the Partnership shall fail to pay the 
Cash Amount to any Redeeming Partner on the Specified Redemption Date 
pursuant to Section 15.1, and the General Partner shall not have elected 
pursuant to Section 15.2(a) to assume the obligations of the Partnership with 
respect thereto, the General Partner shall on the Specified Redemption Date 
contribute to the capital of the Partnership in cash (or, at its election, 
pay directly to the Redeeming Partner the full Cash Amount or GP Shares 
Amount) the full amount necessary to permit the Partnership to satisfy its 
obligations to pay to the Redeeming Partner the Cash Amount on the Specified 
Redemption Date, and the Partnership shall thereupon immediately pay to such 
Redeeming Partner such Cash Amount.

              (c)  The General Partner shall provide the Redeeming Partner 
with at least five (5) days' written notice prior to the Specified Redemption 
Date whether the Redemption Right will be redeemed by the Partnership or the 
General Partner for the Cash Amount or GP Shares Amount. The Redeeming 
Partner may rescind his or its Notice of Redemption at any time prior to the 
Specified Redemption Date if the Redemption Right is to be redeemed for the 
Cash Amount.

              (d)  In the event that the General Partner satisfies the 
Redemption Right in the manner described in Sections 15.2(a) or (b), each of 
the Redeeming Partner, the Partnership, and the General Partner shall treat 
the transaction between the General Partner and the Redeeming Partner for 
federal income tax purposes as a sale of the Redeeming Partner's Partnership 
Units to the General Partner.

                                         -46-


              (e)  Each Redeeming Partner shall execute such documents as the 
General Partner may reasonably require in connection with the issuance of 
Common Shares upon exercise of the Redemption Right, including, without 
limitation, acknowledgment that the shares will be issued without 
registration under the Securities Act, and may not be resold unless 
subsequently registered or an exemption from registration is available.

              (f)  If the Redemption Right is satisfied by the delivery of 
Common Shares, the Redeeming Partner shall be deemed to become a holder of 
Common Shares as of the close of business on the Specified Redemption Date.

         15.3.     Certain Limitations on Redemption Right.  Notwithstanding 
the provisions of Section 15.1, no Limited Partner shall have the right to 
require the Partnership to redeem any Class A Units constituting Collateral 
until such Collateral is required to be released pursuant to the provisions 
of Section 18.3, unless the Limited Partner acknowledges and agrees at the 
time of conversion that the cash paid or Common Shares issued in redemption 
of the Class A Units shall continue to constitute Collateral under Article 
XVIII.

         15.4.     Adjustments.  The number of Common Shares comprising the 
GP Shares Amount shall be subject to adjustment from time to time upon the 
occurrence of certain events, as follows:

              (a)  Adjustment for Change in Shares of Beneficial Interest.  
If at any time after the date of this Agreement, the General Partner:

                   (i)  pays a dividend or makes a distribution on its Common 
Shares in its Common Shares;

                   (ii) subdivides its outstanding Common Shares into a 
greater number of shares;

                   (iii) combines its outstanding Common Shares into a 
smaller number of shares;

                   (iv) makes a distribution on its Common Shares in its 
shares of beneficial interest other than Common Shares; or

                   (v)  issues by reclassification of its Common Shares any 
of its shares of beneficial interest;

then the number of Common Shares comprising the GP Shares Amount shall be 
adjusted so that the holder of a Class A Unit may receive in an exchange 
therefor pursuant to Section 15.2, the number of Common Shares which the 
holder of the Class A Unit would have owned immediately following such action 
if such Unit had been exchanged immediately prior thereto.  In lieu of 
adjusting the 

                                         -47-


number of Common Shares comprising the GP Shares Amount, the General Partner 
may, in its sole discretion, cause an adjustment to be made to the number of 
outstanding Class A Units such that, following any of the actions described 
above, each Class A Unit shall be converted into that number of Class A Units 
equal to the product that results from multiplying one Class A Unit by a 
fraction, the numerator of which is the number of Common Shares that will be 
outstanding immediately following the Record Date for the dividend or 
distribution or the effective date for the subdivision, combination or 
reclassification, as applicable, and the denominator of which is the number 
of Common Shares outstanding immediately prior to the dividend, distribution, 
subdivision, combination or reclassification, as applicable (assuming for 
such purposes that the dividend or distribution was paid on the Record Date). 
 In either case, the adjustment shall become effective immediately after the 
Record Date in the case of a dividend or distribution, and immediately after 
the effective date in the case of a subdivision, combination or 
reclassification.

              (b)  When No Adjustment Required.  No adjustment need be made 
for a change in the par value or no par value of the Common Shares.  

         15.5.     Certain Covenants.  Each Limited Partner covenants and 
agrees with the General Partner that all Class A Units delivered for 
redemption by it pursuant to this Article XV shall be delivered to the 
Partnership or the General Partner, as the case may be, free and clear of all 
Encumbrances.

         15.6.     Certain Changes.  In the event of a merger or 
consolidation of the General Partner with a third party or the sale of all or 
substantially all of the assets of the General Partner or a third party 
acquisition of all of the outstanding Common Shares, the General Partner may 
make such changes to this Article 15 as it deems to be appropriate in order 
to provide that each holder of Class A Units receives, in such transaction, 
or in connection with such transaction, the amount of cash, securities or 
other property which such holder would be entitled to receive if it exercised 
its Redemption Right and received the GP Shares Amount in exchange for its 
Class A Units immediately prior to consummation of such transaction.  If the 
General Partner makes such provision then, in connection therewith, it may 
also terminate or modify the Redemption Right.

                                     ARTICLE XVI

                    LIMITED PARTNER REPRESENTATIONS AND WARRANTIES

         16.1.     Representations and Warranties of the Limited Partners.

              (a)  Each of the Limited Partners hereby represents and 
warrants, severally and not jointly, to the Partnership and the General 
Partner as follows:

                                         -48-


                   (i)  That such Partner, if a corporation, partnership or 
other entity formed pursuant to any statute or other governmental authority, 
is validly formed and in good standing under the laws of the jurisdiction of 
its formation.

                   (ii) That, if such Partner is an Entity, the execution, 
delivery and performance of this Agreement by such Partner has been duly and 
validly authorized by all necessary corporate, partnership, or other similar 
action.  

                   (iii)     That this Agreement has been duly executed and 
delivered by such Limited Partner, and constitutes such Partner's legal, 
valid and binding obligation, enforceable against it in accordance with the 
terms hereof.

                   (iv) That no consent, waiver, approval or authorization 
of, or filing, registration or qualification with, or notice to any 
governmental unit or other person is required to be made, obtained or given 
by such Limited Partner in connection with the execution, delivery and 
performance of this Agreement and the transactions contemplated hereby other 
than consents, waivers, approvals or authorizations which have been obtained 
prior to the date hereof.

                   (v)  That such Partner understands that the Class A Units 
to be issued hereunder and the Common Shares issuable in redemption of Class 
A Units pursuant to Article XV hereof will not be registered under the 
Securities Act, on the grounds that the issuance of such securities is exempt 
from registration pursuant to Section 4(2) of the Securities Act or 
Regulation D promulgated thereunder, and that the reliance of the General 
Partner and the Partnership on such exemptions is predicated in part on the 
Limited Partner's representations, warranties and covenants set forth herein.

                   (vi) That the Units and any Common Shares acquired in 
exchange therefor by such Partner will be acquired for its own account, not 
as a nominee or agent, and without a view to resale or other distribution 
within the meaning of the Securities Act and the rules and regulations 
thereunder and that it will not distribute any such securities in violation 
of the Securities Act.

                   (vii)     That such Partner's principal residence or place 
of business is as set forth on Exhibit A.

                   (viii)    That such Partner understands that the Units and 
Common Shares issued in respect thereof must be held indefinitely unless 
subsequently registered under the Securities Act or an exemption from 
registration is available, and that any routine sales of Common Shares made 
under Rule 144 of the Securities and Exchange Commission under the Securities 
Act may be made only in limited amounts and in accordance with the terms and 
conditions of that Rule and that Rule 144 will not be available for use in 
connection with resales of any shares of Common Shares issued in respect of 
Units for at least one year after the date of issuance or for any Units at 
any time.

                                         -49-



                   (ix) That such Partner is well versed in financial 
matters, has had dealings in securities, including "restricted securities," 
and is fully capable of understanding the type of investment being made in 
the Units and the Common Shares and the risks involved in connection 
therewith.

                   (x)  That such Partner will not sell transfer or otherwise 
dispose of any of the Units or the Common Shares acquired in exchange 
therefor unless such securities have been registered under the Securities Act 
or the holder thereof shall have furnished to the General Partner such 
information as the General Partner may reasonably require to the effect that 
such securities may be sold without registration thereunder.

              (b)  Each Limited Partner also agrees that certificates, if 
any, representing Units or Common Shares issued to it may contain a 
restrictive legend noting the restrictions on transfer described in this 
section and required by federal and applicable state securities laws and that 
appropriate "stop-transfer" instructions may be given to the transfer agent 
for the General Partner and the Partnership.

                                     ARTICLE XVII

                    GENERAL PARTNER REPRESENTATIONS AND WARRANTIES

         17.1.     Representations and Warranties of the General Partner.  
The General Partner represents and warrants to the Partnership and the 
Limited Partners as follows

              (a)  The General Partner is a real estate investment trust duly 
formed and existing under and by virtue of the laws of the State of Maryland.

              (b)  The execution, delivery and performance of this Agreement 
by the General Partner has been duly and validly authorized by all necessary 
trust action of the General Partner. This Agreement has been duly executed 
and delivered by the General Partner, and constitutes a legal, valid and 
binding obligation of the General Partner, enforceable against the General 
Partner in accordance with the terms hereof.

              (c)  No consent, waiver, approval or authorization of, or 
filing, registration or qualification with, or notice to, any governmental

which have been obtained prior to the date hereof.

                                         -50-



                                    ARTICLE XVIII

                                   INDEMNIFICATION

         18.1.     Indemnification.

              (a)  Subject to the provisions of Section 18.2, the General 
Partner hereby indemnifies and holds harmless the Partnership and each 
Limited Partner against and from any and all liabilities, demands, claims, 
actions, causes of action, assessments, losses, fines, penalties, costs, 
damages and expenses (including, without limitation, attorneys' and 
accounting fees and expenses) (any such item, a "Liability," and collectively 
"Liabilities") sustained or incurred by such Limited Partner or the 
Partnership as a result of or arising out of (i) any inaccuracy in any 
representation or warranty made in this Agreement by the General Partner, or 
(ii) any breach by the General Partner of any of its obligations under this 
Agreement.

              (b)  Subject to the provisions of Section 18.2 hereof, each 
Limited Partner who is a Pledgor (as defined in Section 18.3(a)), severally 
and not jointly, indemnifies and holds harmless the Partnership and the 
General Partner against and from all Liabilities sustained or incurred by the 
Partnership or the General Partner as a result of or arising out of (i) any 
inaccuracy in a representation or warranty made under this Agreement by such 
Limited Partner, or (ii) any breach by such Limited Partner of its 
obligations hereunder.  

         18.2.     Limitations on Indemnification Obligations.

              (a)  No indemnified person hereunder shall be entitled to 
indemnification under Section 18.1 hereof unless the indemnified person shall 
have delivered a written notice specifying in reasonable detail the matter 
giving rise to such person's right to indemnification to the indemnifying 
party on or before the second anniversary of the date hereof.

              (b)  No person providing indemnification hereunder shall be 
liable under Section 18.1 hereof unless the total amount recoverable from 
such indemnifying person exceeds, with respect to all indemnities provided by 
such indemnifying person hereunder, an aggregate of $75,000 in the case of 
Safeguard, an aggregate of $75,000 in the case of The Nichols Company, and an 
aggregate of $75,000 in the case of BRT.

              (c)  If a claim for indemnification arises from a third party 
claim asserted against the Partnership, the indemnifying party shall have the 
right, at its own expense, to participate in the defense of the claim, action 
or proceeding which resulted in the claim for indemnification, and if such 
right is exercised, the parties shall cooperate in the defense of such action 
or proceeding; provided, however, the indemnified party shall at all times 
have the right to be in control of such defense.

                                         -51-



              (d)  Indemnification pursuant to Section 18.1 hereof and the 
remedies in respect thereof as set forth in Section 18.3 hereof shall be the 
sole and exclusive remedy of the indemnified parties for any matter covered 
thereby, regardless of the legal theories on which the claim for 
indemnification is based.

         18.3.     Security and Remedies.

              (a)  Each of Safeguard and Nichols, on behalf of themselves and 
their affiliates (collectively, "Pledgors") hereby grants to the Partnership 
a lien upon and continuing security interest in such Pledgor's Class A Units, 
and in any Common Shares issued upon redemption of such Class A Units 
pursuant to Article XV (collectively, the "Collateral") which shall be 
security for the indemnification obligations of such Pledgor hereunder.  The 
indemnification obligation of each Pledgor shall be payable out of such 
Pledgor's entire Collateral, but only from such Collateral. Any transfer by a 
Pledgor of such Pledgor's Class A Units, or Common Shares issued upon 
redemption of Class A Units, shall be subject to the lien and security 
interest granted hereby.  Each Pledgor represents and warrants that his or 
its Class A Units constituting Collateral are owned by it free and clear of 
Encumbrances other than Permitted Encumbrances, which Permitted Encumbrances 
are senior in priority to the lien and security interest created under this 
Section 18.3.

              (b)  Any person claiming indemnification hereunder shall (when 
the amount claimed is known) deliver written notice (the "Indemnity Notice") 
to the party or parties from whom indemnification is claimed describing in 
reasonable detail the rationale for the amount for which indemnification is 
sought.  A Limited Partner shall be entitled to satisfy his indemnification 
obligation by directing the Partnership to cancel in the Register that number 
of Class A Units included in the Collateral as shall be equal in value (based 
on the Current Per Share Market Price of the Common Shares issuable in 
exchange therefor pursuant to Section 15.2 as of the date of the Indemnity 
Notice) to the amount recoverable from such Limited Partner hereunder.  If 
such indemnification obligation shall not have been satisfied by any party 
within thirty (30) days after its receipt of an Indemnity Notice, the matter 
shall be submitted for binding arbitration in accordance with the provisions 
of Article XIX below.

              (c)  In the case of an adverse decision by the arbitrators in 
respect of indemnification being provided by any Limited Partner, if such 
Limited Partner does not satisfy the obligations within ten (10) days after 
the decision is rendered in the arbitration, then the Partnership shall 
cancel in the Register, without the payment of any consideration to or the 
taking of any action required by the Limited Partner, that number of Class A 
Units included in the Collateral as shall be equal in value (based on the 
Current Per Share Market Price of the Common Shares issuable in exchange 
therefor pursuant to Section 15.2 as of the date of the Indemnity Notice) to 
the amount recoverable from such Limited Partner hereunder.  Within ten (10) 
days thereafter, the General Partner shall deliver notice of such 
cancellation to the Limited Partner affected.

                                         -52-


              (d)  The rights of the Partnership and General Partner to 
cancel Collateral shall be the sole and exclusive remedy of the General 
Partner or the Partnership under this Article XVIII and no Limited Partner 
shall have any personal liability hereunder, except as otherwise provided in 
the next succeeding section.

         18.4.     Restriction on Transfer.

              (a)  In connection with the security interests granted by the 
Limited Partners to the Partnership under Section 18.3 hereof, except as 
provided in paragraph (b), the Limited Partners agree that any Class A Units 
owned by such Limited Partners shall not be Transferred, without the consent 
of the General Partner until August 22, 1998.  In addition, in the event that 
notice of a claim for indemnification has been duly given pursuant to Section 
18.2(a) but the matter for which indemnification is sought or the amount of 
the indemnification required to be paid has not been finally determined as of 
August 22, 1998, Class A Units having a sufficient value (based on the 
Current Per Share Market Price at such date of the Common Shares issuable in 
exchange therefor pursuant to Section 15.2) shall remain subject to the 
restrictions of this Section 18.4(a), until such time as the matter in 
question has been finally determined.

              (b)  Nothing in this Agreement shall prohibit the following 
Transfers: (i) transfers occurring by reason of a Limited Partner's exercise 
of his Redemption Rights subject to the pledge of the Common Shares received 
upon redemption pursuant to Section 18.3(a); (ii) transfers by The Nichols 
Company of Class A Units to its equity owners; (iii) transfers by a Limited 
Partner to his or its Affiliates; or (iv) transfers in connection with the 
foreclosure of a Permitted Encumbrance.  In the event of a Transfer permitted 
under clause (ii) or (iii), the transferee shall as a condition of such 
transfer execute an agreement acknowledging that the Class A Units are 
Collateral and are being transferred subject to the Partnership's security 
interest therein.

              (c)  Notwithstanding the foregoing, a Limited Partner may, with 
the consent of the General Partner exercised by its independent trustees in 
their sole and absolute discretion, be relieved of the restrictions on 
transferability contained in this Section 18.4 by (i) consenting to personal 
liability (by execution and delivery of an agreement to such effect in form 
and substance reasonably satisfactory to the General Partner) for any 
indemnification obligations secured by the Partnership Units, or (ii) 
pledging (by execution and delivery of a pledge agreement in form and 
substance reasonably satisfactory to the General Partner) substitute 
collateral which, in the reasonable determination of the General Partner, is 
substantially equivalent in value to the Class A Units then comprising 
Collateral.  In the event that a Limited Partner is relieved of the 
restrictions on transferability in accordance with the terms of this Section 
18.4, the security interest in such Limited Partner's Class A Units hereunder 
shall terminate without further action, and the Partnership, at the request 
of such Limited Partner, shall promptly execute and deliver any document or 
instrument reasonably requested by such Limited Partner to evidence such 
termination.

                                         -53-


         18.5.     No Credit to Capital Accounts.  No payments made by a 
Limited Partner pursuant to this Article XVIII shall be credited to the 
Capital Account of such Limited Partner.

         18.6.     Release of Collateral.  The lien and security interest on 
the Collateral shall terminate on the second anniversary of the date of this 
Agreement, except to the extent provided in the next sentence.  In the event 
that notice of a claim for indemnification has been duly given pursuant to 
Section 18.2(a) but the matter for which indemnification is sought or the 
amount of the indemnification required to be paid has not been finally 
determined at the second anniversary of the date hereof, Class A Units having 
a sufficient value (based on the Current Per Share Market Price at such date 
of the Common Shares issuable in exchange therefor pursuant to Section 15.2) 
shall remain subject to the lien and security created under Section 18.3, 
until such time as the matter in question has been finally determined.

         18.7.     Applicability.  The provisions of this Article XVIII shall 
not be applicable to any Person that becomes a Limited Partner after August 
22, 1996 except as and to the extent agreed to by the General Partner and 
such Person in connection with such Person's admission as a Limited Partner.

                                     ARTICLE XIX

                               ARBITRATION OF DISPUTES

         19.1.     Settlement of Disputes.  The parties will attempt in good 
faith to resolve any and all controversies of every kind and nature between 
the parties to this Agreement arising out of or in connection with the 
existence, construction, validity, interpretation or meaning, performance, 
non-performance, enforcement, operation, breach, continuance or termination 
of this Agreement (each, a "Dispute") promptly by negotiations between senior 
executives of the parties who have authority to settle the Dispute (and who 
do not have direct responsibility for administration of this Agreement).  The 
disputing party shall give the other party written notice of the Dispute. 
Within twenty (20) days after receipt of said notice, the receiving party 
shall submit to the other a written response.  The notice and response shall 
include (a) a statement of each party's position and a summary of the 
evidence and arguments supporting its position, and (b) the name and title of 
the executive who will represent that party.  The executives shall meet at a 
mutually acceptable time and place within thirty days of the date of the 
disputing party's notice and thereafter as often as they reasonably deem 
necessary to exchange relevant information and to attempt to resolve the 
Dispute.  If the matter has not been resolved within sixty (60) days of the 
disputing party's notice, or if the party receiving said notice will not meet 
within thirty days, either party may initiate mediation of the controversy or 
claim in accordance with the Center for Public Resources Model Procedure for 
Mediation of Business Disputes.  

                                         -54-


         19.2.     Arbitration.   

              (a)  If the Dispute has not been resolved pursuant to the 
aforesaid mediation procedure within sixty (60) days of the initiation of 
such procedure, or if either party will not participate in a mediation, the 
Dispute shall be submitted to binding arbitration in accordance with the 
rules of the American Arbitration Association.  The parties further agree 
that all matters shall be governed by the laws of the Commonwealth of 
Pennsylvania.  The parties further agree that any arbitration conducted 
pursuant to this Section shall be held in Philadelphia, Pennsylvania before a 
panel of three (3) arbitrators, one selected by the Partnership, and one 
selected by Safeguard and The Nichols Company, and the third selected by the 
arbitrators selected by the parties.  All deadlines specified in this Section 
may be extended by mutual agreement.

              (b)  The arbitration panel shall have the discretion to include 
in its decision a direction that all or part of the attorneys' fees and costs 
of any party or parties and/or the costs of such arbitration be paid by any 
other party or parties.  On the application of a party before or after the 
initial decision of the arbitration panel, and proof of its attorneys' fees

                                      ARTICLE XX

                    ASSUMPTION OF LIABILITIES AND INDEMNIFICATIONS

         20.1.     Assumption of Liabilities.  The Partnership has assumed 
and shall pay, perform and discharge when due, each of those liabilities and 
obligations that constitute Assumed Liabilities. Obligations of the 
Partnership under this Section 20.1 shall continue to inure to the benefit of 
Partners notwithstanding any subsequent redemption of Units held by them and 
their cessation as Partners in connection therewith.

         20.2.     Indemnification.  From and after the date hereof, the 
Partnership shall indemnify and hold harmless each of the Limited Partners 
and its Affiliates against and from all liability, demands, claims, actions 
or causes of action, assessments, losses, fines, penalties, costs, damages 
and expenses (including, without limitation, reasonable attorneys' and 
accountants' fees and expenses) sustained or incurred by such Limited Partner 
or Affiliate or any assignee or successor thereof (including, without 
limitation, any Substituted Limited Partner) as a result of or arising out of 
any Assumed Liability.  If a claim for indemnification is asserted against 
the Partnership hereunder, the Partnership shall have the right, at its own 
expense, to participate in the defense of any claim asserted against such 
Limited Partner or its Affiliate which resulted in the claim for 
indemnification, and if such right is exercised, the parties shall cooperate 
in the defense of such action or proceeding.

                                     ARTICLE XXI

                                  GENERAL PROVISIONS

         21.1.     Notices.  All notices, offers or other communications 
required or permitted to be given pursuant to this Agreement shall be in 
writing and may be personally served, telecopied, delivered by reputable 
courier service or sent by United States mail and shall be deemed to have 
been given when delivered in person, upon receipt of telecopy or courier 
service or three business days after deposit in United States Mail, 
registered or certified, postage prepaid, and properly addressed, by or to 
the appropriate party.  For purposes of this Section 21.1, the addresses of 
the parties hereto shall be as set forth on Exhibit A hereto.  The address of 
any party hereto may be changed by a notice in writing given in accordance 
with the provisions hereof.

         21.2.     Successors.  This Agreement and all the terms and 
provisions hereof shall be binding upon and shall inure to the benefit of all 
Partners, and their legal representatives, heirs, successors and permitted 
assigns, except as expressly herein otherwise provided.

                                         -56-


         21.3.     Effect and Interpretation.  This Agreement and all of the 
terms and provisions hereof shall be governed by and construed in accordance 
with the law, including the law on conflicts of law, of the State of Delaware.

         21.4.     Counterparts.  This Agreement may be executed in 
counterparts, each of which shall be an original, but all of which shall 
constitute one and the same instrument.

         21.5.     Partners Not Agents.  Nothing contained herein shall be 
construed to constitute any Partner the agent of another Partner, except as 
specifically provided herein, or in any manner to limit the Partners in the 
carrying on of their own respective businesses or activities. Notwithstanding 
anything to the contrary contained herein, no recourse shall be had by the 
Partnership or any Partner against any trustee, director, shareholder, 
officer, employee, agent or attorney of the General Partner under this 
Agreement, and none of the foregoing shall have any personal liability for or 
with respect to any of the foregoing.

         21.6.     Entire Understanding; Etc.  This Agreement constitutes the 
entire agreement and understanding among the Partners and supersedes any 
prior understandings and/or written or oral agreements among them respecting 
the subject matter within.

         21.7.     Amendments.  

              (a)  Except as provided in Sections 21.7(b) and (c), the 
General Partner shall have the power and authority, in its sole discretion 
and without the consent of any other Partner, to amend any and all of the 
provisions of this Agreement to issue additional Partnership Interests, or to 
establish the rights, privileges, duties and obligations of any Partner or 
class of Partnership Interest, or otherwise, except that, without the consent 
of each existing Partner adversely affected thereby, the General Partner 
shall not (except, in each and every case, as may be required to correct 
plain errors or ambiguities in this Agreement) amend this Agreement so as to 
(i) require any Partner to make any additional contribution to the capital of 
the Partnership; or (ii) require any Partner to restore any negative balance 
in its capital account or otherwise to contribute any capital to the 
Partnership, except as required under the Act, the Code or other applicable 
laws or as expressly provided herein.  

              (b)  This Agreement shall not be amended without the prior 
written consent of each Partner adversely affected if such amendment would 
(i) convert a Limited Partnership Interest in the Partnership into a General 
Partnership Interest, or (ii) modify the limited liability of a Limited 
Partner.

              (c)  In addition to the foregoing, for so long as any Class A 
Units remain outstanding, this Agreement may not be amended unless such 
amendment is approved by the holders of at least a majority of the Class A 
Units then outstanding (including the Class A Units held by the General 
Partner), except:

                                         -57-


                   (i)  as otherwise expressly provided herein;

                   (ii) to add to the obligations of the General Partner or 
surrender any right or power granted to the General Partner or any Affiliate 
of the General Partner for the benefit of the Limited Partners;

                   (iii) to reflect the issuance of additional 
Partnership Interests, and the admission, substitution, termination or 
withdrawal of Partners, in each case in accordance with the provisions of 
this Agreement;

                   (iv) to record permitted Transfers of Partnership Units on 
the books of the Partnership;

                   (v)  to reflect a change that is of an inconsequential 
nature and does not adversely affect the holders of the Class A Units in any 
material respect;

                   (vi) to cure any ambiguity or correct plain errors in this 
Agreement; or

                   (vii) to satisfy any requirements, conditions, or 
guidelines contained in any order, directive, opinion, ruling or regulation 
of a federal or state agency or contained in federal or state law.

              (d)  In any matter requiring the vote or consent of holders of 
Class A Units hereunder, Class A Units, if any, held by the General Partner 
will be entitled to be counted in such vote or consent.  

              (e)  This Section 21.7 may not be amended except with the prior 
written consent of the General Partner and the holders of at least a majority 
of the Class A United then outstanding.

         21.8.     Prior Reference Clarification.  All references in the 
Prior Agreement to "Safeguard Scientifics (Delaware), Inc." or "SSI" shall be 
deemed to have been references to Safeguard Scientifics, Inc., a Pennsylvania 
corporation, notwithstanding the stated effective date of this amendment and 
restatement of the Prior Agreement.

         21.9.     Severability.  If any provision of this Agreement, or the 
application of such provision to any person or circumstance, shall be held 
invalid by a court of competent jurisdiction, the remainder of this 
Agreement, or the application of such provision to persons or circumstances 
other than those to which it is held invalid by such court, shall not be 
affected thereby.

                                         -58-


         21.10.    Trust Provision.  This Agreement, to the extent executed 
by the trustee of a trust, is executed by such trustee solely as trustee and 
not in a separate capacity.  Nothing herein contained shall create any 
liability on, or require the performance of any covenant by, any such trustee 
individually, nor shall anything contained herein subject the individual 
personal property of any trustee to any liability.  No recourse shall be had 
for any obligation of the General Partner against any past, present or future 
trustee, shareholder, officer or employee thereof.

         21.11.    Pronouns and Headings.  As used herein, all pronouns shall 
include the masculine, feminine and neuter, and all defined terms shall 
include the singular and plural thereof wherever the context and facts 
require such construction.  The headings, titles and subtitles herein are 
inserted for convenience of reference only and are to be ignored in any 
construction of the provisions hereof.  Any references in this Agreement to 
"including" shall be deemed to mean "including without limitation."

         21.12.    Assurances.  Each of the Partners shall hereafter execute 
and deliver such further instruments and do such further acts and things as 
may be required or useful to carry out the intent and purpose of this 
Agreement and as are not inconsistent with the terms hereof.

         21.13.    Effective Time of Amendment.  This  amendment and 
restatement of the Prior Partnership Agreement shall become effective 
automatically as of November 18, 1997 upon the execution and delivery of this 
Agreement by the General Partner and the holders of 75% or more of the 
outstanding Class A Units (as of the date of this Agreement).
