                          FUNDING COMMITMENT AGREEMENT

     THIS FUNDING COMMITMENT AGREEMENT (this "Agreement"), is entered into as of
October 17, 1996, among HOMESTEAD VILLAGE INCORPORATED, a Maryland corporation
("Homestead"), PTR HOMESTEAD VILLAGE LIMITED PARTNERSHIP, a Delaware limited

Maryland real estate investment trust ("PTR").


                                    RECITALS

     A.   Prior to the date hereof, PTR agreed to make to PTR Homestead Village
Incorporated (the "Prior Corporate Borrower") a loan (the "Corporate Loan"), of
up to a maximum amount of $127,602,594 (the "Maximum Corporate Loan Amount") to
fund, among other things, acquisition and construction costs and expenses
incurred in connection with the acquisition and development of Homestead Village
extended stay lodging facilities.  In connection with agreeing to make the
Corporate Loan, PTR and the Prior Corporate Borrower agreed that the Prior
Corporate Borrower's repayment obligation for funds advanced in respect of the
Corporate Loan would be adjusted by a premium factor of 1.113164866782 (the
"Premium Factor").  To evidence the Prior Corporate Borrower's obligation to
repay the Corporate Loan, at the adjusted rate, the Prior Corporate Borrower has
delivered to PTR an Amended and Restated Promissory Note (the "Corporate Note"),
dated May 28, 1996, in the face amount of $142,042,725 (i.e., the Maximum
Corporate Loan Amount as adjusted by the Premium Factor) (which note amended and
restated a prior promissory note dated January 24, 1996, and delivered by the
Prior Corporate Borrower to PTR to evidence the Corporate Loan), and to secure
the payment obligations under the Corporate Note and the Partnership Note (as
defined below), the Prior Corporate Borrower has, prior to the date hereof,
delivered to PTR deeds of trust and mortgages (the "Existing Corporate Security
Documents"), creating liens on the existing Homestead Village Projects listed in
Exhibit A hereto which are owned by the Prior Corporate Borrower (the "Existing
Corporate Projects").  (The Corporate Note, the Existing Corporate Security
Documents and all other instruments heretofore delivered by the Prior Corporate
Borrower in connection therewith to secure the payment of the Corporate Note and
the Partnership Note are herein called the "Existing Corporate Loan Documents".)

     B.   Prior to the date hereof, PTR agreed to make to the Partnership
Borrower a loan (the "Partnership Loan") of up to a maximum amount of
$71,230,145 (the "Maximum Partnership Loan Amount") to fund, among other things,
acquisition and construction costs and expenses incurred in connection with the
acquisition and development of Homestead Village

                                       1

extended stay lodging facilities.  In connection with agreeing to make the
Partnership Loan, PTR and the Partnership agreed that the Partnership Borrower's
repayment obligation for funds advanced in respect of the Partnership Loan would
be adjusted by the Premium Factor.  To evidence the Partnership Borrower's
obligation to repay the Partnership Loan, at the adjusted rate, the Partnership
Borrower has delivered to PTR an Amended and Restated Promissory Note (the
"Partnership Note"), dated May 28, 1996, in the face amount of $79,290,895
(i.e., the Maximum Partnership Loan Amount as adjusted by the Premium Factor)
(which note amended and restated a prior promissory note dated January 24, 1996,
and delivered by the Partnership Borrower to PTR to evidence the Partnership
Loan), and to secure the payment obligations under the Corporate Note and the
Partnership Note, the Partnership Borrower has, prior to the date hereof,
delivered to PTR those certain deeds of trust and mortgages listed in Part II of
Exhibit A hereto (the "Existing Partnership Security Documents"), creating liens
on the existing Homestead Village Projects listed in Exhibit A hereto which are
owned by the Partnership Borrower (the "Existing Partnership Projects").  (The
Partnership Note, the Existing Partnership Security Documents and all other
instruments heretofore delivered by the Partnership Borrower in connection
therewith to secure the payment of the Corporate Note and the Partnership Note
are herein called the "Existing Partnership Loan Documents"; and the Existing
Corporate Loan Documents and Existing Partnership Loan Documents are
collectively referred to herein as the "Existing Loan Documents".)

     C.   On the date hereof, the parties are entering into a series of
transactions as described in that certain Merger and Distribution Agreement,
dated as of May 21, 1996, among Security Capital Atlantic Incorporated
("Atlantic"), PTR, Security Capital Group Incorporated ("SCG") and Homestead
(the "Merger Agreement"), pursuant to which, among other things, Homestead is,
contemporaneously herewith, acquiring all of the stock of PTR's subsidiaries
which own, operate or develop PTR's Homestead Village extended-stay lodging
facilities.  As a consequence of the mergers contemplated under the Merger
Agreement, the Prior Corporate Borrower has been merged into Homestead and in
connection therewith Homestead has succeeded to and assumed all of the Prior
Corporate Borrower's obligations and liabilities, including those under the
Corporate Note and the Existing Corporate Loan Documents.

     D.   Upon and subject to the provisions of this Agreement, Homestead, the
Partnership Borrower and PTR desire to continue the funding provided for under
the Existing Loan Documents, and in consideration of the issuance, pursuant to
that certain Warrant Purchase Agreement, dated as of May 21, 1996 among
Atlantic, PTR, SCG and Homestead, to PTR by Homestead of warrants to purchase
shares of common stock, $0.01 par value per share, of Homestead ("Homestead
Common Stock"), PTR is willing to provide funds to Homestead and the Partnership
Borrower for the costs incurred in connection with performing due diligence
investigations, securing required development approvals and otherwise completing
the acquisition

                                       12

     Section 2.3.  FUTURE PROJECTS.  The parties acknowledge and agree that the
Future Projects identified in Exhibit A hereto are in differing stages of
consideration by Homestead and that, at any point in the process of its due
diligence review, the negotiation of definitive acquisition and related
documents and its efforts to obtain all Permits required for development of any
such Future Project, Homestead may determine, in its sole and absolute
discretion, either to proceed with the acquisition of the land for, and
development of, any such Future Project or to discontinue its efforts in respect
of any such Future Project.  Requests for advances of Loan proceeds hereunder
may include amounts required to reimburse Homestead for the costs and expenses
incurred by Homestead in its due diligence review of any such Future Project, as
well as all costs incurred in connection with its efforts to secure the Permits
required for development of any such Future Project.  Whenever such pursuit
costs ("Pursuit Costs") are to be funded with Loan proceeds, prior to the first
advance in respect of a Future Project, Homestead will provided PTR with a
notice (a "Funding Notice") identifying the Future Project, together with a
development budget (a "Development Budget") indicating the anticipated costs
that are likely to be incurred prior to the acquisition of such Future Project
by Homestead or a Subsidiary, the amount of such costs to be funded by Loan
proceeds, which amount shall in no event exceed $100,000 per Future Project, and
a schedule setting forth the anticipated time-frames for completing the due
diligence review and obtaining required Permits (a "Development Schedule").

     If Homestead elects to proceed with a Future Project, then Homestead shall
provide PTR at least 10 Business Days' prior written notice (an "Acquisition
Notice") of the anticipated closing date for the acquisition of the subject
Land, the identity of the Borrower for such transaction, and the estimated
amount of Loan proceeds that will need to be advanced at such closing.  From and
after delivery of an Acquisition Notice to PTR, the subject project shall, for
all purposes under this Agreement, be deemed a "Project".  Notwithstanding
anything to the contrary in the foregoing, funding of the first advance of Loan
proceeds in respect of any such Project shall require the recordation of
Security Documents adding such Project as security for the Loan and the
satisfaction of the other conditions set forth in Section 5.2 as to such
Project.

     In the event, however, that Homestead determines from time to time that any
Future Project is unacceptable to it and that Homestead will not expend further
efforts with respect to such Future Project, Homestead shall provide written
notice to PTR identifying any such Future Project.  In such event, any Pursuit
Costs theretofore funded with Loan proceeds, together with accrued and unpaid
interest thereon due under the terms of the Corporate Note, shall be repaid by
Homestead to PTR within 30 days after delivery of such notice to PTR.

     Section 2.4.  SUBSIDIARY LOANS.  With respect to any Future Project for
which an Acquisition Notice is delivered to PTR in accordance with Section 2.3
above, Homestead shall have the right to determine, in its sole and absolute
discretion, that a Subsidiary acquire the
 
                                       13
<PAGE>
 
subject Project, in which event, the subject Subsidiary shall, at such time as
it acquires the subject Future Project, execute and deliver to PTR Subsidiary
Security Documents in connection therewith together with an agreement in form
and substance satisfactory to PTR pursuant to which such Subsidiary agrees to be
bound by the terms of this Agreement as to such Project.  In addition, at the
election of Homestead, the subject Subsidiary shall execute a Subsidiary Note in
the amount of the Loan determined by Homestead to be allocable to such Project
and the Maximum Corporate Loan Amount and/or the Maximum Partnership Loan Amount
(as Homestead may elect) shall be decreased by the amount of any such Subsidiary
Note.  Alternatively, Homestead may elect to have funds advanced with respect to
such Project under the Corporate Loan or Partnership Loan and either loan or
contribute, or cause the Partnership Borrower to loan or contribute, the funds
so advanced to the subject Subsidiary.  In the event any Subsidiary executes a
Subsidiary Note and/or any Subsidiary Security Documents as contemplated under
this Section 2.4, the parties shall, contemporaneously therewith, execute,
deliver, and, if appropriate, record, such amendments to the Loan Documents as
may reasonably be necessary or appropriate to properly document any resulting
changes in the Maximum Corporate Loan Amount and/or the Maximum Partnership Loan
Amount.

     Section 2.5.  DURATION OF FUNDING COMMITMENT.  The obligation of PTR to
advance Loan proceeds in respect of Future Projects for which an Acquisition
Notice has not yet been delivered to PTR shall expire on March 31, 1998 (the
"Expiration Date").  Notwithstanding anything to the contrary in the foregoing,
PTR shall continue to be obligated, subject to and upon the terms and conditions
set forth herein and in the other Loan Documents, to continue to make advances
of Loan proceeds after such date for each Project for which an Acquisition
Notice has theretofore been delivered to PTR under the terms of this Agreement,
but shall not have any obligation to make further advances in respect of Pursuit
Costs for any Future Project for which only a Funding Notice has been delivered
to PTR.  On or before April 30, 1998, Homestead shall repay, or cause to be
repaid, to PTR any advances of Loan proceeds in respect of Pursuit Costs
(together with accrued and unpaid interest thereon) that have not been repaid
pursuant to Section 2.3 hereof as of the Expiration Date.

     SECTION 2.6.  PROJECT SPECIFIC FUNDING COMMITMENT.  PTR's obligation under
this Agreement to make advances of Loan proceeds in respect of a designated
Project shall not exceed the lesser of (i) the actual aggregate hard and soft
costs incurred by the applicable Borrower in connection with the acquisition,
development, design and construction of such Project, or (ii), except as
provided in Section 6.6, the amount allocated to such Project in Exhibit A
hereto, and all costs in respect of a Project in excess of the Loan amount
allocated to such Project shall, except as provided in such Section 6.6, be
funded by Homestead as and when needed.  In addition, PTR's obligation to make
advances in respect of a designated Project shall expire on the second
anniversary of the date on which the subject Land was acquired by

                                       14
<PAGE>
 
Homestead or the applicable Subsidiary.  In the event Final Completion of such
Project has not been achieved by such date, PTR shall have no obligation to make
any further advances of Loan proceeds in connection with such Project and all
costs required to complete such Project shall be funded by Homestead as and when
required in order to assure that such Project is completed and placed in
operation as soon as is reasonably practicable.  If, however, Final Completion
of such Project has not been achieved by the date which is 30 months after the
date of acquisition of the subject Land, then, at the election of PTR, exercised
by delivering written notice to Homestead, Homestead shall repay, or cause the
applicable Subsidiary to repay, within 30 days after receipt of such notice the
amount of Loan proceeds advanced in respect of such Project (together with
accrued and unpaid interest on such amount), and upon receipt of such payment,
this Agreement, solely as it relates to such Project, shall terminate and PTR
shall cause to be released the Security Documents recorded or filed against such
Project.

     Section 2.7.  REPLACEMENT PROJECTS.  Homestead agrees that for each Future
Project rejected by Homestead pursuant to Section 2.3 (a "Rejected Project"),
Homestead will propose to PTR in writing a proposed substitute future project (a
"Proposed Substitute Future Project") to take the place of such Rejected
Project.  Any such Proposed Substitute Future Project shall be located within
the Geographic Area and, except as specifically noted in writing by Homestead,
shall conform, to Homestead's then current knowledge, to the Prototypical
Project requirements.  Homestead may select a Proposed Substitute Future Project
from its then contemplated Homestead Village projects which Homestead is
considering pursuing or, if all such contemplated projects are then already
included within the list of Future Projects under this Agreement, then Homestead
may delay in identifying a Proposed Substitute Future Project until, in the
ordinary course of its business, a new site for a contemplated Homestead Village
project is identified within the Geographic Area.  Homestead shall not, however,
be obligated to identify a new potential Homestead Village site solely for the
purposes of presenting to PTR a Proposed Substitute Future Project.

     PTR shall have a period of 20 Business Days after receipt of any such
Proposed Substitute Project to approve or reject, in its sole and absolute
discretion, any such proposal, and failure of PTR to provide Homestead with
written notice within such 20-Business Day period shall be deemed a rejection by
PTR of the subject Proposed Substitute Future Project.  If PTR timely approves a
Proposed Substitute Future Project, then such project shall be substituted in
the place and stead of the Rejected Project in Exhibit A hereto, and shall for
all purposes under this Agreement thereafter be deemed a Future Project.  The
maximum amount of Loan proceeds that will be available to fund such Future
Project (if Homestead thereafter delivers an Acquisition Notice for such
Project) shall be equal to the Loan amount originally allocated to the
applicable Rejected Project in Exhibit A.
 
                                       15
<PAGE>
 
     In the event that any Proposed Substitute Future Project is rejected or
deemed rejected by PTR, Homestead shall be free to pursue the Proposed
Substitute Future Project on its own.  For each Rejected Project, Homestead
shall be required (subject to the limitations set forth above) to propose to PTR
up to a maximum of three (3) Proposed Substitute Future Projects.  If PTR
rejects all three (3) Proposed Substitute Future Projects submitted by Homestead
in respect of a particular Rejected Project, then the Maximum Loan Amount, and
PTR's funding commitment hereunder, shall be reduced by the amount allocated to
the Rejected Project in Exhibit A hereto.  The obligation of Homestead to
propose to PTR Proposed Substitute Future Projects shall in any event terminate
on the Expiration Date.

     Section 2.8.  RELEASE OF SECURITY DOCUMENTS.  The parties acknowledge and
agree that the Notes are convertible, in whole or in part, into shares of
Homestead Common Stock up to the maximum amount of the unpaid principal amount
of such Notes outstanding from time to time and otherwise pursuant and subject
to the terms and conditions of such Notes.  Any such conversion shall reduce the
amount of the debt evidenced by the Notes and secured by the Security Documents
by the amount determined in accordance with the conversion provisions of the
Notes.  In connection with any partial conversion of the Notes, Homestead may
request that, in lieu of or in addition to reducing the amount secured by the
Security Documents, PTR release any one or more of the Projects then subject to
the Security Documents and having a value equivalent to or less than the amount
of the debt reduction resulting from such  conversion.  The release of any
Projects from the lien of the Security Documents shall, however, be subject to
the approval of PTR, which approval shall not to be unreasonably withheld or
delayed.

     At such time as all amounts owing to PTR under or in respect of any of the
Loan Documents have been paid in accordance with the provisions of the Loan
Documents or if not paid  then, to the extent permitted under the Notes,
converted into Homestead Common Stock, and when PTR has no further obligation to
make any advance, disbursement or payment of any kind or to extend credit under
or with respect to any of the Loan Documents, then this Agreement shall
terminate and upon receipt of demand therefor from Homestead, PTR shall execute
and deliver to Homestead appropriate instruments of release or reconveyance of
any Security Documents then in effect.


                                   ARTICLE 3.

<PAGE>

funds by PTR) as follows:

     Section 3.1.  EXISTENCE AND POWER.  Homestead and each Borrower is duly

engaged, and to own and develop each Project which it owns.

     Section 3.2.  AUTHORIZATION AND BINDING OBLIGATIONS.  The borrowing
evidenced by the Notes and the execution, delivery and performance of this
Agreement and all other Loan Documents by Homestead and each Borrower (i) are
within the power of the subject entity and (ii) have been duly authorized.  Each
of the Loan Documents executed by Homestead and/or any Borrower, when executed
and delivered, will constitute the legal, valid and binding obligations of such
entity and are enforceable against such entity in accordance with its respective
terms, subject to bankruptcy and insolvency laws, equitable principles, and laws
affecting creditors rights generally.

     Section 3.3.  NO LEGAL BAR OR RESULTANT LIEN.  None of the (i) execution
and delivery of, (ii) fulfillment of the terms and conditions of, or (iii) the
consummation of the transactions contemplated by the Loan Documents to which
Homestead and/or any Borrower is a party (a) violate any provisions of the
articles or certificate of incorporation, bylaws or partnership agreement of
such entity, (b) violate or constitute a default under any contract, agreement
or instrument, or any law, ordinance, rule or regulation of any Governmental
Authority, to which such entity is subject, (c) to such entity's knowledge,
violate or constitute a default under any Governmental Requirement so as to
create a Material Adverse Effect or (d) to such entity's knowledge, result in

     Section 3.4.  NO CONSENT.  The execution, delivery and performance of the
Loan Documents to which Homestead and/or each Borrower is a party does not
require the consent or approval of any other person, including, without
limitation, any financial institution or other creditor of such entity, any
trustee, conservator, receiver or administrator, or any regulatory authority or
governmental body of the United States of America or any state thereof or any
Governmental Authority.

     Section 3.5.  COMPLIANCE WITH LAWS.  All Plans, Projects,  Properties,
Improvements and their intended use presently comply, and throughout the term of
this Agreement will continue to comply, in all material respects with all
Governmental Requirements and all public

<PAGE>
 
and private restrictions or other agreements affecting each such Property,
including, without limitation, building codes, special use permits, zoning
codes, Environmental Laws, applicable requirements of fire underwriters,
restrictive covenants, easements and other agreements affecting the Property.
All Permits currently required by Governmental Requirements to be obtained for
the Projects now subject to this Agreement have been obtained, and neither
Homestead nor any Borrower has any reason to believe that any Permits that
subsequently may be required to enable it to construct, occupy, operate, use or
sell any of the Property will not be obtained in due course.

     Section 3.6.  LITIGATION.  Except as disclosed to PTR in writing, at the
date of this Agreement there is no litigation, legal, administrative, or
arbitral proceeding, investigation or other action of any nature pending or, to
the knowledge of Homestead or any Borrower, threatened against or affecting any
Borrower or Homestead that involves the possibility of any judgment or liability
(not fully covered by insurance) that would have a Material Adverse Effect.

     Section 3.7.  DEFAULTS.  To the knowledge of Homestead and each Borrower,
neither Homestead nor any Borrower is in default, and no event or circumstance
has occurred that, but for the passage of time or the giving of notice, or both,
would constitute a default, in any respect under any agreement of instrument
that may have a Material Adverse Effect.  No Event Default has occurred
hereunder.

     Section 3.8.  STATUS OF PROPERTY.  The Borrower delivering any Security
Documents to PTR is the fee simple owner of the subject Property free and clear
of all restrictions, covenants, easements, liens and encumbrances, including,
without limitation, mechanics', materialmen's and suppliers' liens (except liens
securing PTR and matters reflected in the Title Policy).  To Homestead and each
Borrower's knowledge:  each Property is a legal lot under applicable laws,
statutes, ordinances and regulations of the governing jurisdiction; each
Property is carried, or is in the process of being changed so as to be carried,
on the tax rolls of the governing jurisdiction as a separate, subdivided parcel;
each Property has, or will have upon completion of construction, full access to
the public highways and to the services of all utilities, including water, storm
sewer, sanitary sewer, electricity and telephone, required to serve the intended
use of the Property; each Property under construction or completed is zoned
under applicable zoning laws and ordinances so as to permit the construction and
development of the Project planned for such Property and the use and occupancy
of the Property as contemplated under this Agreement; and each Property under
construction or completed currently complies in all material respects with such
laws and ordinances and with all private restrictions applicable thereto and any
special use permit, variance, exception, or other special zoning authorization
applicable thereto; each Property currently complies in all material respects
with all Governmental Requirements
 
                                       18
<PAGE>
 
applicable thereto. To Borrower's knowledge, the liens of the Security Documents
executed by it are valid liens covering the subject Properties.

     Section 3.9.  USE OF PROCEEDS.  None of the proceeds of the Loans has been
or shall be used to purchase or carry, or to reduce or retire or refinance any
credit incurred to purchase or carry, any margin stock (within the meaning of
Regulations G and U of the Board of Governors of the Federal Reserve System) or
to extend credit to others for the purpose of purchasing or carrying any margin
stock.

     Section 3.10.  REAL PROPERTY ENVIRONMENTAL MATTERS.  To the actual
knowledge of Homestead and each Borrower, except as disclosed in the
environmental audits prepared for Homestead and/or any such Borrower and
delivered to PTR, no hazardous substances or solid waste are located at or on or
have been disposed of or otherwise released on or to any of the Properties in
violation of any Environmental Laws.

     Section 3.11.  FINANCIAL CONDITION.  All financial statements delivered to
PTR concerning Homestead and each Borrower fairly and accurately present the
financial condition of such entities as of the date of such statements and have
been prepared in accordance with generally accepted accounting principles
applied on a consistent basis, and there are no contingent liabilities not
disclosed thereby which would have a Material Adverse Effect.  Since the close
of the period covered by the latest financial statements delivered to PTR with
respect to Homestead's and each Borrower's assets, liabilities, or financial
condition, no event has occurred (including, without limitation, any litigation
or administrative proceedings) and no change in such entities' financial

as may reasonably be necessary for PTR to evaluate the proposed Material Change.
PTR shall deliver written notice to Homestead within 10 Business Days after
receipt of the requested Material Change stating whether such Material Change

                       PROCEDURE FOR ADVANCES; RESERVES

     Section 6.1.  GENERAL.  PTR will disburse the proceeds of the Loans on a
monthly basis for the cost categories set forth in the applicable Development
Budgets and Project Budgets.  Homestead shall submit a written request for
advance in a form approved by PTR by the 25th day of each month and, provided
PTR determines that all conditions precedent to the advance

                                      29
<PAGE>
 
have been satisfied, disbursements will be made by the 1st day of the
immediately following month.  Each request for advance shall set forth, on a
Project-by-Project basis, Homestead's reasonable estimate of the hard and soft
costs and expenses incurred during the month just ending and for which
reimbursement is being sought.  With each request for advance after the first,
Homestead shall also provide a reconciliation indicating the amount by which the
immediately preceding advance made by PTR exceeded the actual hard and soft
costs for the period covered by such advance and the amount by which the request
for advance for the month just ending has been adjusted on account of any over-
or underpayment by PTR for the preceding month.  With respect to the final
advance of Loan proceeds in respect of a Project, if the final reconciliation
submitted in the month following such advance reflects that Loan proceeds in
excess of actual costs were advanced, such overpayment (together with accrued
and unpaid interest thereon) shall be repaid by Borrower to PTR within 15 days
after such reconciliation is delivered to PTR.  Any additional Loan proceeds
owing to Borrower on the basis of such final reconciliation shall be advanced by
PTR with the balance of the monthly advance made by PTR under this Section 6.1.

     All disbursements with respect to any request for an advance submitted
other than on the 25th day of a month will be made within ten (10) business days
after the later of (i) receipt by PTR of a written request for an advance from
Homestead in a form approved by PTR and (ii) PTR's determination that all
conditions precedent to the advance have been satisfied.

     All disbursements shall be made in accordance with any instructions
contained in the Homestead request for advance.

     Section 6.2.  PAYMENTS TO PTR. Notwithstanding any other provisions of this
Agreement, PTR may, at it's option and without notice or authorization by
Homestead or any Borrower, use any Loan proceeds to pay, as and when due, any
interest on the Loans.  The parties acknowledge that the Loans provide for
interest reserves in amounts sufficient to pay all interest due and payable in
respect of each Project through completion of same, and Homestead and each
Borrower specifically authorizes PTR to advance portions of such interest
reserves to pay interest on the Loans as and when the same comes due.

     Section 6.3.  RETAINAGE AND CONTRACTOR'S FEE HOLDBACK.  The parties
acknowledge that PTR shall retain, and Homestead shall not request disbursement,
of any retainages provided for under any Construction Contract, which amounts
shall be retained by PTR to secure full and complete performance of all
construction obligations hereunder (hereinafter, the "Retainage Holdback").
Provided no Default exists hereunder, PTR shall disburse the Retainage Holdback
in accordance with the provisions of the applicable Construction Contract as
requested by Homestead in its requests for advances.  Upon the occurrence of a
Default hereunder, PTR shall

                                      30
<PAGE>
 
have no obligation to make further disbursements from the Retainage Holdback,
and no Borrower shall be entitled to any such disbursements, until such Default
is cured.  Upon the occurrence of an Event of Default hereunder, PTR may apply
the Retainage Holdback against any of the obligations secured by the Security
Documents as PTR sees fit or, in PTR's discretion, to the completion of any
incomplete Improvements.  Subject to the foregoing terms and provisions, to the
extent not theretofore disbursed, PTR will disburse the amounts in the Retainage
Holdback in respect of a Project concurrently with the Final Advance for such
Project.

     Section 6.4.  INTEREST RESERVE.  PTR shall, on the date hereof, withhold
from the proceeds of the Loans available for distribution the amount of Seven
Million, Nine Hundred Five Thousand, Four Hundred Sixty-Six Dollars ($7,905,466)
(the "Interest Reserve").  Provided no Default exists hereunder, the Interest
Reserve shall be disbursed for the payment of interest on the Loans as such
interest becomes due and payable.  Upon the occurrence of a Default hereunder,
PTR shall have no obligation to make further disbursements from the Interest
Reserve, and no Borrower shall be entitled to any such disbursements, until such
Default is cured.  Should interest payable on the Loans exceed the amount of the
Interest Reserve, the Borrowers shall promptly pay such amounts.  Upon the
occurrence of an Event of Default, PTR may apply any undisbursed portion of the
foregoing reserve against any of the obligations secured by the Security
Documents as it sees fit or, at PTR's discretion, to the completion of and
incomplete Improvements.

     Section 6.5.  OWNER'S CONTINGENCY.  The parties acknowledge that each
Project Budget shall contain an owner's contingency (an "Owner's Contingency")
equal to no less than 2% of Project hard and soft costs contained within the
Project Budget.  Provided no Default exists hereunder, the Owner's Contingency
for a Project shall be disbursed by PTR to the subject Borrower to cover
unanticipated Project costs, costs associated with change orders and hard and
soft cost overruns (before such Borrower or Homestead, as guarantor under the
Completion and Payment Guaranty, shall be required to cover such additional
costs pursuant to the provisions of Section 6.6 hereinbelow or the Completion
and Payment Guaranty) as and when such payments are due and payable.  Requests
for disbursement of portions of the Owner's Contingency shall be made with
Homestead's monthly requests for advance of Loan proceeds.  Upon the occurrence
of a Default hereunder, PTR shall have no obligation to advance any portion of
the Owner's Contingency until such Default is cured.  Upon the occurrence of an
Event of Default, PTR may apply the Owner's Contingency against any of the
obligations secured by the Security Documents as PTR sees fit, or at PTR's
option, to the completion of any incomplete Improvements.

     Section 6.6.  COST OVERRUNS AND SAVINGS; CHANGE ORDER RESERVE.  In the
event that the costs to acquire and complete any Project in its entirety,
including, without limitation, the

                                      31
<PAGE>
 
furnishing thereof, exceed the amount of Loan proceeds available for the subject
Project (including the applicable Owner's Contingency), then the subject
Borrower shall with its own funds pay all costs and expenses which may be
required to complete the subject Project as and when such costs and expenses
become due and payable.  In the event the costs to acquire and complete any
Project are less than the amount of Loan proceeds allocated to the subject
Project, then the unapplied portion of the Loan proceeds (including any
unexpended portion of the applicable Owner's Contingency and amounts required to
be refunded by Borrower under Section 6.1 for any overpayments of Loan proceeds
made in the final advance for a Project) shall be retained by PTR as a reserve
for Change Orders on other Projects which are made in accordance with the
requirements of this Agreement (the "Change Order Reserve").  Provided no
Default exists hereunder, the Change Order Reserve shall be disbursed by PTR to
any Borrower from time to time to cover the costs of Change Orders to the extent
any such Change Order results in Project costs exceeding the Project Budget,
including the Owner's Contingency, for such Project (before such Borrower or
Homestead, as guarantor under the Completion and Payment Guaranty, shall be
required to cover such additional costs pursuant to the provisions of this
Section 6.6 or the Completion and Payment Guaranty).  Requests for disbursement
of portions of the Change Order Reserve shall be made with Homestead's monthly
requests for advance of Loan proceeds.  Upon the occurrence of a Default
hereunder, PTR shall have no obligation to advance any portion of the Change
Order Reserve until such Default is cured.  Upon the occurrence of an Event of
Default, PTR may apply the Change Order Reserve against any of the obligations
secured by the Security Documents as PTR sees fit or, at  PTR's option, to the
completion of any incomplete Improvements.


                                  ARTICLE 7.

                               EVENTS OF DEFAULT

any sums required to be paid under the Notes, the Security Documents, this
Agreement or any other Loan Documents, and such failure is not cured within 10

any of the other Loan Documents other than as set forth elsewhere in this
Article 7 (for which no additional grace or cure period is given by this Section
7.2, or the existence of any breach or inaccuracy in any of the representations,
covenants or warranties set forth in this Agreement or in any of the other Loan
Documents, provided, however, that (i) no Event of Default shall exist hereunder

any of the other Loan Documents (other than this Agreement) until Homestead or
such Borrower, as applicable, shall have failed to cure such breach within any
applicable notice and cure period therein provided; and (ii) no Event of Default
shall exist hereunder on account of a breach of any representation, warranty or
covenant contained herein unless and until PTR shall provide written notice of
such breach to Homestead or such Borrower and such entity shall fail to cure the
same within 30 days after receipt of such notice, provided if such breach is of
such a nature that it cannot be cured within such 30 day period, it shall not
constitute an Event of Default hereunder so long as Homestead or such Borrower,
as applicable, commences its cure of such breach within such 30 day period and
thereafter diligently and continuously proceeds with the curing of same within a
reasonable period of time not to exceed 180 days.

     Section 7.3.  JUDGMENT OR ATTACHMENT.  The entry by any court of a final
judgment in excess of $500,000 against Homestead or a Borrower that is not
satisfactorily stayed or discharged within 30 days from the date thereof, or any

shall not be released, stayed or otherwise provided for to PTR's satisfaction
within 30 days after the occurrence thereof; provided that in the case of a
stay, Homestead or the subject Borrower, as applicable, shall have reserved for
the full amount thereof.

     Section 7.4.  VIOLATION OF GOVERNMENTAL REQUIREMENTS.  The institution of
any judicial or administrative proceeding alleging that any of the Improvements
violate any Governmental Requirements if such violation gives rise to a Material
Adverse Effect and the failure to have such proceeding dismissed or such
violation corrected within 30 days after the institution thereof, except that
Homestead or the applicable Borrower shall have the right to contest any such
proceeding beyond such 30 day period, provided that PTR is satisfied that the
prosecution of such proceeding will neither have any Material Adverse Effect nor
materially impair PTR's security.

     Section 7.5.  INSOLVENCY, ETC.  The occurrence of any of the following:

     (a) Homestead or any Borrower shall generally not pay its debts as they

<PAGE>
 
     (b) Homestead or any Borrower shall commence any case, proceeding or other
action seeking reorganization, arrangement, adjustment, liquidation, dissolution

receiver, trustee, custodian or other similar official for it or for all or any
substantial part of its property;

     (c) Homestead or any Borrower shall take any corporate action to authorize

bankruptcy, insolvency, reorganization or relief of debtors, or seeking
appointment of a receiver, trustee, custodian or other similar official for it
or for all or any substantial part of its property, and such case, proceeding or
other action (i) results in the entry of an order for relief against it which is
not fully stayed within 15 Business Days after the entry thereof or (ii) remains
undismissed for a period of 60 days.

     Section 7.6.  UNAPPROVED TRANSFER.  Any sale, conveyance, transfer,
disposition, alienation, hypothecation, leasing (except in the ordinary course
of business) or further encumbrancing of a Project, or any portion thereof or
any interest therein, by any Borrower, other than any conveyance of a portion of
the unimproved land associated with such Project which is in excess of what is
needed for such Project (which conveyance is permitted), or a sale, conveyance,
transfer, disposition, alienation, hypothecation or encumbrancing of any legal
or equitable interest in a Borrower or Homestead in violation of the Loan
Documents shall be an Event of Default as of the date of such transfer, without
any right to cure.  In the case of a permitted conveyance of excess land, as
hereinbefore provided, Lender shall, upon request of Homestead, execute a
partial release, releasing the lien of any Security Documents applicable to such
excess land.


                                  ARTICLE 8.

                                   REMEDIES

     Section 8.1.  GENERAL.  Upon the occurrence of any Event of Default an
defined in Article 7 of this Agreement, PTR, at its option, shall have the
following rights and remedies:

                                      34
<PAGE>
 
     (a) PTR may declare any one or more of the Notes to be immediately due and
payable, whereupon the Notes shall become forthwith due and payable without
presentment, demand, protest or further notice of any kind.

     (b) PTR  may bring a foreclosure action with respect to the Security
Documents, take possession of any one or more of the Properties or exercise any
other remedy provided for in the Security Documents.

     (c) PTR shall be entitled to proceed simultaneously, or selectively and
successively, to enforce its rights and remedies under the Notes, the Security
Documents, the Completion and Payment Guaranty or this Agreement, and to
exercise any or all other rights and remedies available to PTR at law or in
equity.

     (d) In the event PTR shall elect to enforce its rights selectively under
any one or more of the Loan Documents, such action shall not be deemed a waiver
or discharge of any lien or encumbrance securing payment of the Notes until such
time as PTR shall have been paid in full all sums due under the Notes or secured
by the Security Documents, including any sums advanced or disbursed pursuant to
this Agreement.  The foreclosure of any lien provided pursuant to this Agreement
or the Security Documents, without the simultaneous foreclosure of all such
liens, shall not merge the liens granted which are not foreclosed with any
interest which PTR might obtain as a result of such selective and successive
foreclosure.

     (e) PTR shall have the right, but not the obligation, to take possession of
any one or more of the Properties and proceed to complete the Improvements
thereto according to the applicable Plans.  For this purpose, each Borrower
hereby conditionally assigns to PTR as additional security for the repayment of
the Loans all of each such Borrower's rights to the Plans for the Projects owned
by it, any contracts pertaining to the Project owned by such Borrower, whether
for construction, sale or otherwise, and any Permits pertaining to the subject
Property(ies); provided, PTR shall, upon occurrence of an Event of Default, have
the option to exercise this assignment, but shall not be obligated to accept
this assignment or to assume any liability of any Borrower under any such Plans,
contracts or Permits.  Furthermore, each Borrower hereby constitutes and
appoints PTR as its true and lawful attorney-in-fact with full power of
substitution to complete, or cause to be completed, the Improvements owned by
such Borrower in the name of such Borrower and hereby empowers said attorney or
attorneys as follows: (i) to use any funds of Borrower, including any balance
that may be held in escrow and any funds which may remain unadvanced hereunder,
for the purpose of completing the Improvements being built by such Borrower;
(ii) to make such additional changes and corrections in the Plans for such
Improvements as may reasonably be necessary or desirable to complete such
Improvements in substantially the manner contemplated by the Plans for such

                                      35
<PAGE>
 
Improvements and in a good and workmanlike manner; (iii) to employ such
contractors, subcontractors, agents, architects and inspectors as shall be
required for said purposes; (iv) to pay, settle or compromise all existing bills
and claims that are or may become liens against the subject Property(ies) or any
part thereof or may be necessary or desirable for the completion of the subject
Improvements or the clearance of title; (v) to execute all applications and
certificates in the name of Borrower which may be required by law or by any
contract relating to the subject Improvements; and (vi) to do any and every act
with respect to the applicable Property(ies) which such Borrower may do in its
own behalf.  It is understood and agreed that this power of attorney shall be
deemed to be a power coupled with an interest which cannot be revoked.  PTR, as
attorney-in-fact, shall also have the power to defend, to the extent PTR
reasonably deems necessary, at such Borrower's cost, all actions or proceedings
in connection with the subject Improvements and Property(ies).  At the time PTR
takes possession of a Property(ies), or any part thereof, all materials on such
Property owned by Borrower shall become the property of PTR for the purpose of
completing the subject Improvements.  In addition, any materials or equipment
paid for with the proceeds of the Notes but stored at a location other than the
subject Property(ies) shall become the property of PTR when it takes possession
of the subject Property(ies).  Such Borrower shall pay PTR the cost of
completion.  Each Borrower hereby authorizes PTR to add such costs to the
indebtedness of the Borrowers to PTR, which costs shall be secured by the
Security Documents.  Any of the foregoing actions by PTR shall not relieve the
Borrowers of their responsibility to repay the Notes.  The foregoing provision
shall not be construed as creating any third party beneficiary contract and
nothing in the foregoing shall be construed as giving or conferring any rights
or benefits whatsoever to or upon any other person or entities other than the
parties to this Agreement.  Homestead shall indemnify, defend and hold harmless
PTR from and against any and all claims, liabilities, loss, damages, suits,
actions, expenses (including reasonable attorneys' fees) and costs arising from
any actions taken by PTR in accordance with the power of attorney herein granted
except to the extent attributable to the gross negligence or willful misconduct
of PTR.

     (f) PTR shall not have any obligation to make any advances under the Notes
pursuant to this Agreement after the occurrence and during the continuance of an
Event of Default and at any time during such period, may unilaterally elect to
terminate any obligation of PTR to make any future advances under the Notes
pursuant to this Agreement.

     Section 8.2.  REMEDIES CUMULATIVE.  No failure or delay by PTR in the
exercise of any rights or remedies available to it under the Loan Documents or
at law or in equity shall operate as a waiver thereof, nor shall any single or
partial exercise by PTR of any such right or remedy preclude any further
exercise thereof or of any other right or remedy.  The remedies provided in the
Loan Documents or available at law or in equity are cumulative and not
alternative.

shall, without the prior written consent of PTR, which consent PTR may withhold
in its sole discretion, directly or indirectly assign, transfer or convey (i)
this Agreement or any of the other Loan Documents, (ii) any of Borrower's rights
or obligations under any of the Loan Documents, (iii) any portion of the

agreement, and supersedes all other prior agreements and understandings, both

<PAGE>
 
     Section 9.11.  NO JOINT VENTURE OR PARTNERSHIP.  Nothing contained in this
Agreement or in any of the other Loan Documents and no other aspect of the
relationship between Homestead or any Borrower and PTR shall be construed as
creating a partnership, joint venture, or other relationship of or between

and borrower.  All rights and obligations granted to or undertaken by either of
the parties hereto shall be construed as incidents of such lending relationship.

     Section 9.12.  NO THIRD PARTY BENEFICIARY RIGHTS CREATED.  The parties
hereto expressly declare that it is their joint and mutual intention that this

copies, each of which shall constitute an original, and all of which together
shall constitute one and the same document.

     Section 9.15.  SCOPE OF REVIEW OF PLANS.  Neither the approval of the Plans
nor any subsequent inspections or approvals of the Improvements during
construction shall constitute a warranty or representation by PTR or any of its
agents, representatives or designees as to the technical or legal sufficiency,
adequacy or safety of the structures or any of their component parts, including
without limitation fixtures, equipment or furnishings, nor shall such approvals
or inspections constitute such a warranty or representation as to the subsoil
conditions involved in the Property or any other physical condition or feature
pertaining to the Property.  All acts, including any failure to act, relating to
the Property by any agents, representatives or designees of PTR are performed
solely for the benefit of PTR to assure repayment of the Loans and are not for
the benefit of Borrower or any other person, including without limitation
purchasers, guests or other occupants.

rights, liens and claims for any of the proceeds and advances under the Notes to
the liens, operation and effect of the Security Documents.

     Section 9.18.  INDEMNITY.  Homestead and each Borrower agree to indemnify,
defend and hold PTR harmless from and against any and all claims, injuries,
damages and liabilities that may be asserted or claimed against PTR by any

as a result or by reason of, the construction contemplated herein or the
operation of the ownership or Encumbered Property or any part thereof.

     Section 9.19.  Limitation of Liability.  Any obligation or liability
whatsoever of PTR which may arise at any time under this Funding Commitment
Agreement or any obligation or liability which may be incurred by it pursuant to
any other instrument, transaction or undertaking contemplated hereby shall be
satisfied, if at all, out of PTR's assets only.  No such obligation or liability
shall be personally binding upon, nor shall resort for the enforcement thereof
be had to, the property of any of its shareholders, trustees, officers,
employees or agents, regardless of whether such obligation or liability is in
the nature of contract, tort or otherwise.
