                        MEETING DATE:  JANUARY 21, 1997
To the Members:

     A Special Meeting (the "Meeting") of the Members of WhiteRock Portfolio
Investors, L.L.C. (the "Company") will be held on Tuesday, January 21, 1997 at
2:00 P.M., Central Prevailing Time, at the offices of Brazos GenPar, Inc., the
Company's Administrator, located at 600 N. Pearl Street, Suite 1500, Dallas,
Texas, 75201 for the following purposes:

     1.  To ratify various actions taken by the Board of Managers by unanimous
written consent in lieu of a meeting to elect two additional Managers, and at

accountant for the Company and other actions in furtherance of compliance with
the Investment Company Act of 1940;

     2.  To approve the following amendments to the Company's Limited Liability
Company Agreement ("Operating Agreement"):


     (a)  amendments with respect to approval of Unit transfers and admittance
          of new Members directly by the Unitholders rather than the Board of
          Managers, and changing those persons to whom various dissolution
          events may apply, each of which amendment is designed to provide an
          alternative method for the Company to obtain various desired
          attributes respecting its entity classification as a partnership for
          certain tax purposes, and corresponding amendments to delete certain
          requirements previously applicable to the Managers as a group;

                                       i

          basis between meetings of the Board of Managers, and to allow for
          appointment of certain subordinate officers;

     (e)  an amendment designed to match the ability of the Company to call
          Capital Commitments from its Members more closely with the Company's
          obligation to meet its own capital commitments with respect to its
          portfolio investments;

     (f)  amendments designed to eliminate the obligation of the Company to send
          all tax filings, returns and correspondence of the Company to each
          Member automatically rather than upon request;

     (g)  an amendment to enable the Managers to make certain ministerial or
          corrective amendments to the Operating Agreement, or those required by
          law or otherwise advisable, without the vote of the Members, provided
          various protections of those parties affected are in place;

     (h)  amendments to expand the definition of Qualified Investment and extend
          the termination date of the Company designed to permit additional
          flexibility in seeking to invest a portion of the Company's assets in
          real estate related investments on a global basis;

     (i)  an amendment to create a Unit dividend reinvestment plan for the

          undefined in the Definitions section of the Operating Agreement, and

          notice provisions and other factual matters referenced in the

Company's Board; to reelect Nori Gerardo and William Peressini as Managers to
the Company's board, and to reduce the number of vacant Board positions by one
for a total of four;

     4.  To approve various Unit issuances, capital calls, transfers of Units
among certain Members and the admission of certain new Members of the Company;
and

     5.  To transact such other business as may properly come before the Meeting
or any adjournment thereof.

     THE BOARD OF MANAGERS HAS PREVIOUSLY CONSIDERED AND RECOMMENDS FOR APPROVAL

                                January 21, 1997

     This proxy statement is furnished in connection with the solicitation by
the Board of Managers of WhiteRock Portfolio Investors, L.L.C. (the "Company")
of proxies to be voted at a Special Meeting of Members to be held on Tuesday,
January 21, 1997, and any adjournment thereof.  The purposes of the Meeting are
set forth in the accompanying Notice of Special Meeting of Members dated January
6, 1997.  All capitalized terms used herein or in the Notice have the meanings
assigned to them in the Company's Limited Liability Company Agreement (the
"Operating Agreement").

     This proxy solicitation will be made primarily by mailing this proxy
statement and the accompanying proxy card to Members commencing on January 6,
1997.   Supplementary solicitations may be made by telephone, telegram or by
personal interview.  Brazos GenPar, Inc. (the "Administrator"), 600 N. Pearl
Street, Suite 1500, LB 164, Dallas, Texas 75201, and Officers and Managers of
the

                                       v
<PAGE>
 
Company who participate in such solicitations will receive no special
compensation for their services.  The expenses of preparing and mailing this
proxy statement and its enclosures and all other solicitation expenses will be
paid by the Administrator.

     If the enclosed proxy is executed properly and returned in time to be voted
at the Meeting, and is not revoked, the Units represented thereby will be voted
according to the instructions marked on the proxy.  If no instructions are
marked on an otherwise properly executed proxy, the Units represented thereby
will be voted in favor of proposals 1 - 4 (and all subparts of each proposal) as
listed on the Notice of Special Meeting.

                   OUTSTANDING UNITS AND VOTING REQUIREMENTS

     The Board of Managers has fixed the close of business on December 16, 1996
as the record date for purposes of determining Unitholders eligible to vote at
the Meeting and any adjournments thereof.  As of December 16, 1996, there were
1,374,023 Units of the Company issued and outstanding.  The PacifiCorp
Master Retirement Trust is the only record holder of the Company that has a
beneficial interest in 5% or more of the Company's outstanding Units.  Only
Units of record at the close of business on that date

                                       vi
<PAGE>
 
are entitled to notice of and to vote at the Meeting.  Each such Unitholder is
entitled to one vote for each full Unit of participation, and a proportionate
vote for each fractional Unit, of the Company held on the record date.

     The holders of a majority of the outstanding Units of the Company must be
present in person or represented by proxy at the Meeting in order to constitute
a quorum for the transaction of any business.  If a quorum is present at the
Meeting but sufficient votes to approve one or more of the items on the agenda
are not received, the persons named as proxies may propose one or more
adjournments of the Meeting to permit further solicitation of proxies with
respect to those items.  In so doing, the persons named as proxies will attempt
to determine if an adjournment and additional Unitholder solicitation are
reasonable and in the best interest of Members, and will vote for or against
adjournment accordingly.   Any such adjournment will require the affirmative
vote of a majority of the Units present at the Meeting or represented by proxy.

     If the enclosed proxy is executed properly and returned in time to be voted
at the Meeting, and is not revoked, the Units represented thereby will be voted
according to the instructions marked on the proxy.  The persons voted as proxies
will use their best judgment in

                                      vii
<PAGE>
 
voting in connection with the transaction of such other business as may properly
come before the Meeting or any adjournment thereof.  A Member giving a proxy may
revoke it at any time before it is executed by a vote thereon by giving written
notice of its revocation to the Secretary of the Company at the address
indicated on the Notice of Special Meeting, by executing and delivering to the
Company another proxy dated subsequent to the proxy to be revoked, or by
attending the Meeting and voting in person.

     Abstentions will not be counted for or against any proposal to which they
relate, but will be counted for purposes of determining the Units present at the
Meeting.  Abstentions will therefore have the effect of a "no" vote for purposes
of obtaining the requisite approvals of the proposals before the Meeting.

     The Company will promptly furnish a copy of its most recent annual report
and the most recent semi-annual report to any Member upon request.  Such
requests should be directed to

     The Company's Board of Managers has no separate nominating, compensation or
audit committee, or any committee performing similar functions, although Mr.
Wirkkala was designated in April, 1996 to serve as liaison for the Board in
connection with the services to be provided by the Company's independent
accountant.  The Board as a whole acts in these capacities.

     As of December 16, 1996, all Managers and Officers of the Company as a
group owned approximately 0.29% of the Company's outstanding securities.

     No per meeting attendance fees have been authorized for any of the
Managers.  For fiscal 1995, no compensation was paid to any "disinterested"
Board member for attendance at any regularly scheduled meeting of the Board.
The Company has no bonus, profit-sharing, pension or retirement plan.

          Ratification of Selection of Auditors
          -------------------------------------

     At a meeting of the Board of Managers held April 3, 1996, a majority of the
Board, including a majority of

                                       x
<PAGE>
 
Managers who are not "interested persons" of the Company, selected KPMG Peat
Marwick to serve as independent certified public accountants for the Company for
the fiscal years ending December 31, 1995 and December 31, 1996.  Under the
Investment Company Act of 1940 ("Investment Company Act"), such a designation
remains subject to the right of the Company, by a Majority-in-Interest Vote of
the Unitholders at any meeting called for the purpose, to terminate such
employment immediately without penalty.   KPMG Peat Marwick has no direct or
material indirect ownership interest in the Company.  The Investment Company Act
requires the Board's selection to be submitted to Unitholders for ratification
or rejection at the next annual meeting of the Unitholders.  Insofar as the
Company's Operating Agreement does not require regular annual meetings, the
Company is taking the opportunity to secure ratification by the Unitholders at
the Meeting of such appointment of KPMG Peat Marwick.

     A representative of KPMG Peat Marwick is expected to attend the Meeting.
The representative will be given an opportunity to make a statement and will be
expected to respond to any appropriate questions from Unitholders.

     other than a pro rata basis among all Members or Persons having such
     unfulfilled Capital Commitments, so long as any additional Units to be
     issued are fully paid for in cash at the time of their issuance.   Except
     in connection with Unit purchases effected in connection with the Unit
     dividend reinvestment plan of the Company established by Section 3.4(a)
     hereof, to the extent an existing Member desires to increase its Capital
     Commitment, it shall submit to the Company a new Admission Agreement with
     the amount of the additional Capital Commitment indicated therein.  The
     President may accept such additional Capital Commitment on behalf of the
     Company, but only after consulting with and receiving no objection from
     either a Majority of the Managers or a Majority-in-Interest of the Members.

                    ---------------------------------                        
     Member to the Company is limited to its Capital Commitment as specified in
     its Admission Agreement or Schedule A hereof, as either may be amended from
     time to time by agreement of the Company and such Member or to reflect 
     the Capital Commitments made by Admission Agreements.  Such Capital
     Commitments, at the time they are

     contribution of capital, loan, or otherwise.

     no fewer than three members at all times, and each of whom shall be an
     individual Member over 21 years of age qualified to serve as a director
     under the 1940 Act (the "Managers"), and no more than 60% of whom may be

     capacity as such shall have the authority or capacity to bind the Company 
     or conduct its business.  The Managers shall act on behalf of the Company 
     only as a body and, except as required by the 1940 Act or the rules 
     issued thereunder, such action shall be carried either by an affirmative
     vote of a Majority of the Managers cast at a meeting duly called and at
     which a quorum of one third of all Managers is present, or alternatively,
     by unanimous written consent. Similarly, no Member in its capacity as such
     shall have the authority or capacity to bind the Company or conduct its
     business, but shall have only such voting and other management and
     participation rights as are specifically set forth herein.

     resold or Transferred by the Member without appropriate registration or the
     availability of an exemption from such requirements; (d) Transfer of the
     Units is further subject to the discretionary approval of the President 
     and the Members pursuant to the terms hereof; (e) it meets one or
     more of the following requirements: (i) it is an "accredited investor"
     within the meaning of Section 501(a) of Regulation D promulgated under the
     1933 Act; or (ii) it or its authorized representative (A) has sufficient
     knowledge or experience in financial and business matters to enable an
     evaluation of the merits and risks of owning one or more Units in the
     Company, and (B) has access to all of the information that would otherwise
     be available to it if the offering of the Units were registered

               (a)  No Member may Transfer all or any part of its Ownership
     Interest in the Company or substitute the transferee as a new Member
     without obtaining the prior approval of the President and approval by
     written consent or vote held at a meeting by those Members
     holding more than 50 percent of the outstanding Units (calculated without 
     regard to the Units held by the Transferring Member in either the 
     numerator or the denominator), which approval may be withheld in the sole 
     and absolute discretion of the President and each Member; provided, 
                                                               --------

     successor-in-interest to Mr. Crandall's Unit position who has agreed to
     maintain a one percent Ownership Interest in the Company for tax purposes)
     may grant a security interest in Distributions to be made with respect to
     his Units, and such grant shall not be considered a "Transfer" for purposes
     of this Agreement nor shall any transfer made to the grantee in connection
     with such a security interest make the grantee or transferee a Member of
     the Company unless the consents otherwise required by this Agreement are
     received.

     Ownership Interest (or any portion thereof) shall be admitted as a Member
     (a "Substituted Member") and admitted to all the rights of the Member who
     initially assigned the Ownership Interest, only with the prior approval of
     the President and by written consent or vote held at a meeting by those 
     non-Transferring Members holding more than 50 percent of the outstanding
     Units (calculated without regard to the Units held by the Transferring
     Member in either the numerator or the denominator), which approval may be
     withheld in their the sole and absolute discretion of the President and
     each Member. If so admitted pursuant to the terms of Article III hereof,
     the Substituted Member shall have all the rights and powers and is subject
     to all the restrictions and liabilities of the Member originally having the
     Ownership Interest. The admission of a Substituted Member, without more,
     shall not release the Member originally assigning the Ownership Interest
     from any liability to the Company that may have existed prior to the
     approval.

     permit the President or any other Officer designated by the
     President to admit Additional Members and, consistent with the terms

     held by the Dissociating Member in either the numerator or the
     denominator), which approval may be withheld in the sole and absolute

     Explanation:  Under Internal Revenue Service ("IRS") authorities existing
     -----------                                                              
at the time the Company was organized, whether an entity had at least three of
the "corporate"

                                      xix
<PAGE>
 
characteristics of limited liability, continuity of life, centralized management
and free transferability of interests determined whether the entity will be
considered by the IRS as an association taxable as a corporation or,
alternatively, a partnership with essentially "pass-through" tax status for
Federal tax purposes. In appropriate circumstances, these requirements could be
satisfied by reference solely to the designated managers of a limited liability
company rather than the members generally. The Operating Agreement currently
takes this approach, requiring the Managers (who approve the admission or
substitution of new Members and to whom certain of the dissolution events apply
exclusively) collectively to satisfy certain requirements set forth in IRS
Revenue Procedure 95-10, 1995-3 I.R.B. 20 ("Rev. Proc. 95-10"), which procedure
addresses the tax classification of limited liability companies generally.
Specifically, Section 4.1, by reference to the "Rev. Proc. 95-10 Member-Manager
Requirements" proposed for deletion above, requires the Managers collectively to
maintain one percent ownership of the Company's outstanding Units as suggested
by Rev. Proc. 95-10 with respect to member-managed limited liability companies.
(Although Rev. Proc. 95-10 provides a safe harbor for those entities
seeking rulings from the IRS as to their classifications,

                                       xx
<PAGE>
 
the Company has not sought, nor does it currently intend to seek such a
ruling.)

     On December 17, 1996, the Internal Revenue Service  promulgated new
regulations (the "check-the-box" regulations) simplifying the Federal entity tax
classification rules applicable to limited liability companies such as the
Company, and which provide additional flexibility to the Company for purposes of
its Federal tax classification.  See Treasury Regulation (S) 301.7701-1 et seq.
                                 ---                                    -- ---  
Some, but not all of the states, are expected to follow the new Federal
classification rules, in whole or in part.

     In any event, it is no longer anticipated that the Managers will maintain
the necessary ownership to ensure pass-through tax classification for all state
and Federal purposes simply by virtue of satisfying the Rev. Proc. 95-10
requirements.  In this regard, however, requiring the Managers to comply with
the one percent ownership requirement set forth in Rev. Proc. 95-10 is not the
exclusive method by which the Company may be deemed to have the attributes
needed for classification as a partnership.  In Rev. Proc. 95-10, the IRS
recognizes that a limited liability company also may satisfy the requirements
for pass-through tax treatment by applying the four

                                      xxi
<PAGE>
 
characteristics discussed above to the members as a whole. Moreover, it is
expected that, at least in the near term, this "four factor" approach may
continue to be followed in a number of states notwithstanding the promulgation
by the IRS of the new Federal tax regulations. Therefore, pending counsel's
review of the position taken by the various states with regard to the new
Federal classification regulations, the amendments listed above are designed to
enable the Company to continue to be classified as a partnership for most state
tax purposes without regard to the provisions affecting solely the Managers, by
appropriately limiting the transferability of Units and admission of new
Members, as well as the continuation of the Company upon certain dissolution
events, by (1) vesting power to approve certain admissions and substitutions
directly in the Members (acting through a majority vote of the outstanding
Units), and (2) applying dissociation events to all of the Members rather than
just the Managers. The amendments to the form of Admission Agreement are largely
conforming changes.

     In addition to the tax related amendments discussed above, the amendment of
the quorum language in Section 4.1 noted above is discussed in the following
section.

 Clarification of Various Quorum and Voting Percentages
 ------------------------------------------------------

     Proposed Amendments:  In addition to the proposed amendment of Section 4.1

noted above which would change the quorum requirement for the Board from "two"
Board members to "one third," a corresponding change to Section 4.2(b) is
proposed as follows:

     4.2  ELECTION, TENURE, AND REMOVAL OF MANAGERS 
          -----------------------------------------            
               . . . .

    
               (b) Upon any vacancy on the Board of Managers, unless otherwise
     required by law, the remaining Managers shall elect each successor Manager
     by a unanimous vote of the remaining Managers; provided, however, that in
                                                    --------  -------         
     the event of any vacancy on the Board where the Managers cannot agree by
     unanimous vote within 10 days on a successor Manager qualified to serve
     hereunder or whenever at least one third of the remaining Managers have
     been previously elected by the Managers without subsequent ratification by
     the Members, election of any new Manager, who shall be qualified to serve
     hereunder, shall instead be by Majority-in-Interest Vote of the Members,
     who may either vote to fill such vacancy at that time or, alternatively, to
     reduce the number of Managers then serving to the number then remaining in
     office if not less than three; and provided, further, that the Managers may
     thereafter vote to again increase such number to not more than five at any
     later time pursuant to and subject to the requirements of Section 4.2(d)
     hereof.      

     Explanation:  The amendments to Sections 4.1 and 4.2 clarify the quorum
     -----------                                                            
requirements and conform them with the Investment Company Act by stating the
number of Managers constituting a quorum as a fraction of the total Board (one
third) rather than an absolute number.  These amendments are made necessary by
the increase in the number of Managers from three to five shortly after the
Company was formed.

(In connection with Proposal no. 3, however, the Unitholdersare being asked to
approved a reduction in the number of Managers to four on a going forward
basis.) The use of a portion of the Board, stated as a fraction, will also be
self-correcting in the event the number of Board members changes again in the
future.

                         Recusal Procedure for Managers
                         ------------------------------
     Proposed Amendment:  Section 11.6 shall be amended in relevant part as
     ------------------                                                    
follows:
    
               11.6  RIGHTS OF MANAGERS AND OFFICERS TO CONDUCT OTHER  BUSINESS;
                     ----------------------------------------------------------
     CONFLICTS OF INTEREST.  Subject to the requirements of Section 17 of the
     1940 Act and the provisions of any Company Code of Ethics adopted pursuant
     to Rule 17j-1 under the 1940 Act, nothing contained in this Agreement shall
     be deemed to restrict in any way the freedom of each Member, Manager, or
     Officer, Brazos and each of their Affiliates, including any director,
     manager, officer, or employee of such Person, to conduct any other business
     or any other activity whatsoever, including without limitation, the
     acquisition, holding and disposing of real estate, Securities or assets of
     any entity whether or not such activities would also have been appropriate
     for the Company, and without having or incurring any obligation to offer
     any interest therein to the Company or any Member.  No Manager or Officer
     shall be deemed to have a conflict of interest by virtue of any such
     activity or by virtue of its employment by or relationship to Brazos or any
     of its Affiliates or the activities undertaken by them.  To the extent any
     Manager believes that he or she may have a conflict of interest with
     respect to any matter to be considered by the Managers, such Manager shall
     promptly disclose such conflict to the other Managers, and thereafter shall
     recuse himself or herself from further consideration of such matter.  To
     the fullest extent allowed by applicable law, any action taken by the other
     Managers with respect to such matter may be taken if approved or ratified
     by the requisite percentage or written consent of the Managers pursuant to
     the terms hereof without counting for these purposes the recused Manager or
     Managers in either the numerator or denominator, and any action that could
     otherwise be taken or ratified by unanimous written consent may be effected
     instead by the unanimous written consent of the non-recused Managers.  Any
     such action may also be taken or ratified pursuant to the Majority-in-
     Interest Vote of the Members.       

                                      xxiv

     Explanation:  This amendment provides a procedure whereby a Manager may
     -----------                                                            
recuse itself in the event of a conflict of interest.

                        Officer Succession and Vacancies
                        --------------------------------
     Proposed Amendment:  Sections 4.5 and 4.10 of the Operating Agreement shall
     ------------------                                                         
be amended in relevant part to read as follows:
    
               4.5  ELECTION, TENURE, AND REMOVAL OF OFFICERS.  At all times,
                    -----------------------------------------                
     the Managers shall have elected by Majority Vote a President, one or more
     Vice-Presidents, a Treasurer, and a Secretary to serve as the Officers and
     authorized agents of the Company.  A person may hold more than one office
     in the Company except that no person may serve concurrently as both
     President and Secretary of the Company.  Officers may but need not be
     Members or Managers.  Each Officer shall hold office at the pleasure of the
     Board of Managers or until his or her failure to qualify for such position
     pursuant to the terms hereof, death, resignation, or removal with or
     without cause by a Majority Vote of the Managers.  Any vacancy in a Board
     of Managers-appointed Officer position other than the President shall be
     filled on an interim basis prior to the next meeting of the Managers as
     provided herein, or, if not provided herein, at the direction of the
     President.  Any vacancy in the position of President shall be filled on an
     interim basis by the Treasurer, and if both positions are vacant, then by
     that Vice President previously designated to fill such role, if any, by the
     President or the Board of Managers, and if none, then by the Vice President
     with the longest length of service with the Company or, to the extent two
     or more Vice Presidents have the same length of service, by the one whose
     last name appears first alphabetically.  In the event only one Officer
     shall remain at any time, then regardless of his or her position such
     Officer shall exercise the powers of the President on an interim basis
     until election of one or more replacements by the Managers.  In the absence
     of any Officers, authority to operate the Company shall reside solely in
     the Managers or any other duly authorized designee of the Managers.      

     . . . .
    
               4.10  SUBORDINATE OFFICERS; COMMITTEES.  By notice to the
                     -------------------------------- 
     Managers, the Treasurer may appoint an Assistant Treasurer and the
     Secretary may appoint up to two       

                                      xxv
<PAGE>
 
    
     Assistant Secretaries, each of whom shall be fully qualified to serve
     as the Treasurer or Secretary, respectively. The Board of Managers may
     also from time to time authorize any committee or Officer to appoint
     assistant and subordinate Officers. Election or appointment of an Officer,
     employee or agent, whether by action of the Managers or otherwise, shall
     not in and of itself create contract rights. As to any assistant or
     subordinate Officer, any committee or Officer authorized hereby or by the
     Managers or which appointed such assistant or subordinate Officer in
     the first place may remove such Officer.  The removal of an Officer does
     not prejudice any of his or her contract rights, if any.     

     Explanation:  The proposed amendment is designed to clarify the line of
     -----------                                                            
succession should vacancies in the Company's primary Officer positions arise, as
recently occurred, and to provide for the appointment of certain subordinate
Officers in the Operating Agreement itself rather than requiring a subsequent
Board resolution.  The clarification is needed because in the past, the Company
has had several Vice-Presidents at one time.  Under the amendment, these would
succeed the President and Treasurer in clear order of priority.  The President
would also be able to appoint replacements to fill vacancies on an interim basis
between Board meetings.


            Reinstatement of Original Capital Commitment Obligations
            --------------------------------------------------------
              to the Extent of Refunds Distributed to the Members
              ---------------------------------------------------

     Proposed Amendments:  Section 3.2(c) shall be amended to read as follows:
     -------------------                                                      

          (c) On or prior to the date of admission of any Additional or
     Substituted Member, and prior to the issuance of any additional Units to an
     existing Member, each such

                                      xxvi
<PAGE>
     
     Member agrees to and shall make a Capital Contribution in the amount,
     if any, and at the time or times (each, a "Closing") set forth
     opposite its name on Schedule A or its Admission Agreement or as
     may be stated in any Capital Call (as defined below) issued
     by the Company in accordance with this Agreement; provided, however, that
                                                       --------  -------      
     any Additional Member or Substituted Member for whom the Company has
     previously received a Capital Contribution with respect to any Unit(s) to
     be registered on the books and records of the Company in the name of such
     Member pursuant to the terms hereof shall not be required to make any
     additional contribution at the time of such Member's admission.
     The total amount of capital that each Member or Person seeking admission
     as a Member agrees to contribute to purchase Units shall be set forth
     and designated as its "Total Capital Commitment" on Schedule A or its
     "Total Remaining Commitment" on its Admission Agreement, as the
     case may be, and any part of such commitment that remains unfulfilled
     at any time may be called by the Company upon ten Business Days
     Notice to such Member or potential Member (a "Capital Call").
     For these purposes, to the extent the Company receives any refund
     attributable to an investment made by the Company that does not reduce the
     original capital commitment made by the Company with respect to such
     investment, then the amount of any distribution made to the Members on
     account of the Company's receipt of such refund (excluding, however, any
     amount attributable to interest on such refund) shall be added back, on a
     pro rata basis, to the amount of any previously reduced remaining Capital
     Commitment of the Members so as to remain available to be redrawn by the
     Company as part of each Members' Total Capital Commitment.  All such
     refunded amounts shall be accounted for by the Company to the Members. 
     

     A corresponding change shall be made to Section

4.14 ("Major Actions") as follows:
    
               (b)  Causing the Company to make any Capital Call with respect to
     any outstanding Capital Commitment after the aggregate amount of prior
     Capital Contributions made to the Company and not subsequently refunded
     exceeds $15 million, without the prior approval of the Managers; provided,
                                                                      -------- 
     however, that the President or any other Officer authorized by the
     -------                                                           
     President may make Capital Calls prior to the time such limit is exceeded
     without regard for further direction from the Managers so long as such
     Capital Calls are made to enable the Company to meet any legal obligation
     that was previously duly approved by the Managers.       


     Explanation:  This amendment is designed to enable the Company to meet its
     -----------                                                               
capital commitments with respect to

                                     xxvii
<PAGE>
 
investments it has made. For example, the Company's initial investment was in
Brazos Fund, L.P. Pursuant to the Amended and Restated Limited Partnership
Agreement governing Brazos Fund, L.P. (the "Brazos LPA"), however, as a limited
partner in Brazos Fund, L.P. the Company has received various distributions in
the nature of refunds of its original capital contributions to Brazos Fund,
L.P., together with interest thereon, each time that an additional limited
partner has been admitted to Brazos Fund, L.P. subsequent to the date of the
Company's own admission as a partner therein. (Each of these admissions also
effectively lowered the overall percentage interest of the Company as a partner
in Brazos Fund, L.P.) The Brazos LPA, however, provides that the amount of such
refunds increases the remaining capital commitment of the limited partners
receiving the refunds (for example, the Company), so that such amounts
effectively remain available to be redrawn by Brazos Fund, L.P. as originally
agreed with the affected limited partner. The Company's Operating Agreement
currently does not have a similar "redraw" provision, and thus, to the extent
the Company desires to distribute to its own Members such refunds received from
Brazos Fund, L.P. or with respect to other past or future investments that may
also be structured in this manner (e.g., the Company's recent investment in the

                                     xxviii
<PAGE>
 
Lone Star Opportunity Fund, L.P.), rather than retaining them for immediate
reinvestment, the Company could either find itself obligated on such investments
without the ability to draw already contributed and refunded capital from its
own Members, or, to prevent such shortfalls, the Company could be forced to
retain a greater share of such distributions in anticipation of additional calls
from Brazos Fund, L.P. or similarly structured investments of the Company.

                       and Correspondence to All Members
                       ---------------------------------

     Proposed Amendment:  Section 9.4 of the Operating Agreement shall be
     ------------------                                                  
amended as follows:

    
               9.4  ANNUAL REPORT.  Within sixty (60) days after the end of each
                    -------------                                               
     Company Fiscal Year, the Managers shall cause to be prepared and furnished
     to each Member (a) the balance sheet of the Company dated as of the end of
     the Fiscal Year then ended; (b) a related statement of cash flow and income
     or loss for the Company for the same year, together with a report thereon
     by a firm of independent certified public accountants selected in
     accordance with this Agreement and the 1940 Act with respect to the audit
     of such financial statements by such firm; (c) a statement of change in net
     assets and liabilities of the Company for the same year; and (d) a list of
     investments held by the Company during such Fiscal Year; and (e) such other
     information as is required by the 1940 Act.      

               9.4.1  COST OF REPORTS AND AUDITS.  The expenses incurred in
                      --------------------------                           
     furnishing the reports and information, as well as the annual audit of the
     books and records of the Company, as required by this Article IX, shall be
     borne by Brazos.

               9.4.2  PREPARATION AND FILING OF INCOME TAX  RETURNS AND OTHER
                      -------------------------------------------------------
     WRITINGS.  The Managers shall cause the preparation and timely filing of
     --------                                                                
     all Company tax returns, shall on behalf of the Company make such tax
     elections,

                                      xxix
<PAGE>
 
    
     determinations, and allocations as appear to be appropriate, and shall
     timely make all other filings required by any governmental authority having
     jurisdiction to require such filing, the cost of which shall be borne by
     the Company. The Managers shall also cause to be delivered to the Members,
     within ninety (90) days after the expiration of each tax year of the
     Company, a Form K-1 prepared by the Company's accountant. This form shall
     show the allocation of profit or loss of the Company for Federal income tax
     purposes, including all separately stated items, to each Member. No
     election shall be made by the Company or any Member to be excluded from the
     application of the provisions of subchapter K of the Code or from any
     similar provision of state tax laws. Upon the distribution of any Asset of
     the Company to any party hereto, the Company, at the Managers' option, may
     file an election in accordance with applicable Treasury Regulations to
     cause the basis of any Asset to be adjusted for federal income tax purposes
     as provided in sections 734, 743, and 754 of the Code.      
    
               9.4.3  CONTROVERSIES WITH THE INTERNAL REVENUE  SERVICE.  In the
                      ------------------------------------------------         
     event of any controversy with the Internal Revenue Service or any other
     taxing authority involving the Company or any individual Member or Members,
     the outcome of which may adversely affect the Company, directly or
     indirectly, or the amount of the allocation of income, gain, loss,
     deduction, or credit of the Company to such Member, the Company may, at its
     option, incur expenses it deems necessary or advisable in the interest of
     the Company in connection with any such controversy, including, without
     limitation, reasonable attorneys' and accountants' fees.  Brazos is hereby
     designated by the Members as the "tax matters partner" of the Company as
     defined in Section 6231(a)(7) of the Code and in such capacity shall
     represent the Company in any disputes, controversies or proceedings with
     the Internal Revenue Service.  The Company will promptly send to each
     Member that requests it a copy of all correspondence sent to or received
     from the Internal Revenue Service by the Company during the one year
     period prior to receipt of the request.       
     
     Explanation:  The Operating Agreement currently provides that all tax
     -----------                                                          
returns and related correspondence will be transmitted to all of the Members
automatically.  Insofar as the Members will at all times number at least 100,
and each has the right to inspect and copy all such returns and correspondence
at the offices of the

                                      xxx
<PAGE>
 
Administrator, the amendments are designed to eliminate the more burdensome
requirements of automatic distribution to all Members while still affording them
reasonable access to the information.


                Procedure for Amending the Operating Agreement
                ----------------------------------------------

     Proposed Amendment:  Section 13.1 shall be amended to read as follows:
     ------------------                                                    

               13.1  AMENDMENT.
                     --------- 
    
               (a) Any provision of this Agreement may be amended by Majority-
     in-Interest Vote of the Members, or by the Managers as they deem necessary
     or desirable without the vote of the Members if needed to supply any
     omission, to cure, correct or supplement any ambiguous, defective, or
     inconsistent provision hereof or provision containing factual information
     no longer current, to conform this Agreement to the requirements of the
     Act, the Code, the 1933 Act, the 1940 Act, ERISA, or any other applicable
     laws or regulations, and in such instances upon a vote of two-thirds in
     number of all Managers then serving at a meeting of the Managers duly held
     or by their unanimous written consent in lieu of a meeting, but neither the
     Members nor the Managers shall be liable for failing to do so, and provided
     further that no amendment of this Agreement shall, without the consent of
             ----                                                             
     the affected Member or Manager, as the case may be (i) increase the
     liability of a Member beyond the liability of such Member expressly set
     forth in this Agreement or as applicable, its Admission Agreement, or
     otherwise modify or affect the limited liability of such Member or the
     liability of any Manager or agent of the Company; (ii) change the maximum
     Capital Contribution required of any Member (other than as provided in this
     Agreement or its Admission Agreement); (iii) change the method of
     allocations made under the provisions of Articles VII, VIII, and XV hereto
     to any Member (except as allowed by this Agreement); or (iv) change any
     rights with respect to any Unit in the Company by reducing the amount
     payable thereon upon liquidation of the Company or by diminishing or
     eliminating any voting rights pertaining thereto, without a two-thirds in
     interest approval of the Members and, to the extent such amendment
     materially and adversely affects the rights and obligations of a Manager or
     Member hereunder, the affirmative consent of any affected Manager or Member
     or alternatively with respect to such Member, granting it the right to
     immediate redemption of its Units.       
     
                                      xxxi
<PAGE>
 
          (b) For any amendment the Managers shall deliver to each Member, as
     provided for in Section 13.1, written notice requesting if necessary such
     Member's consent and upon receipt of the required consents and execution of
     the documents setting forth the amendment, such amendment shall become
     effective.  Any alleged amendment hereto that is not so documented shall be
     ineffective.
    
          (c)  Notwithstanding any other provision of this Agreement, the
     Managers are also specifically authorized, upon the advice of legal counsel
     for the Company that doing so will not adversely affect the pass-through
     tax status of the Company, to amend any or all of Sections 3.1(b), 10.1(a),
     10.3, 10.4, and 15.1(c) of this Agreement to require approval of transfers,
     substitutions, admissions, and continuation of the Company upon the
     happening of a dissolution event in a manner other than by vote of the
     Members holding more than 50 percent of the outstanding Units, and any such
     amendment shall become effective without the approval of any other Member.
     All such amendments shall be provided promptly to the Members.       
     
     Explanation:  This amendment will accomplish two purposes.  First, it will
     -----------                                                               
make it easier for management to update the Operating Agreement to correct
errors, clarify ambiguities, and take other necessary or advisable actions
without calling a meeting of the Members, given the substantial expense that is
incurred in doing so.

     Second, the amendment adding subsection "(c)" is designed to give the
Managers of the Company the flexibility, without the need for further approval
by the Members, to revise sections of the Operating Agreement imposing
restrictions on the Company designed to satisfy the rules on partnership tax
classification discussed in subsection 2(a) above.  The amendment would make it
easier to take advantage of the increased flexibility if the check-the-box
procedures recently adopted by the Internal Revenue

                                     xxxii
<PAGE>
 
Service are followed in the states where the Company does business. Any changes
in the current requirements, however, would only be made with advice of legal
counsel.

               Qualified Investment Definition; Termination Date
               -------------------------------------------------

     Proposed Amendments:  The definition of "Qualified Investment" and Section
     -------------------                                                       
2.3 shall be amended to read as follows, and the Termination Date shall be
extended as indicated:

    
          "QUALIFIED INVESTMENT" shall mean any real estate related investment
     of any kind or type, including any investment in any direct or indirect
     interest (whether characterized as equity, debt, or otherwise) in any of
     the following:  (i) any Real Property; (ii) any loan or other obligation
     relating to any Real Property (whether performing or non-performing); or
     (iii) any Security issued by, or any other interest in, any entity directly
     or indirectly engaged primarily in the business of acquiring, developing,
     constructing, managing, operating, holding, and/or disposing of any Real

     that the Real Property and other real estate related investments
     comprising or relating to each Qualified Investment shall, over
     the life of the Company, be targeted to include Real Property and other
     real estate related investments not less than 50% of which are located in

     2.3  INVESTMENT OBJECTIVES AND POLICIES OF THE COMPANY.
     ---  ------------------------------------------------- 

          (a)  The investment objective of the Company shall be to seek high
     total returns by buying, selling, exchanging or otherwise acquiring,
     holding, trading, investing in, managing, and dealing with Qualified
     Investments, whether such assets are acquired directly, or indirectly
     through

                                     xxxiii
<PAGE>
 
    
     partnerships, joint ventures, or otherwise. In pursuing its objectives, the
     Company shall focus primarily on acquiring, directly or indirectly,
     managing and disposing of distressed debt (including mortgage loans) and
     owned real estate ("REO") portfolios, single asset acquisitions, operating
     companies, development opportunities, tax exempt bonds, limited partnership
     interests, and high yield commercial mortgage-backed Securities, including
     but not limited to investing in entities organized or to be organized by
     Brazos and its Affiliates. The investment objectives and policies of the
     Company are set forth in more detail in Schedule B hereof, which is
     incorporated herein by reference. Subject to the terms and conditions of
     this Agreement, the Company shall have the power and authority to do all
     such other acts and things as may be necessary, desirable, expedient,
     convenient for, or incidental to, the furtherance and accomplishment of the
     foregoing objectives and policies and for the protection and benefit of the
     Company, including investing in any other types of incidental non-real
     estate related assets that are part of a Qualified Investment.     
     
     Explanation:  These amendments clarify and broaden the definition of real
     -----------                                                              
estate related investments in which the Company may invest to enable the Company
to be less constrained in its international focus both with respect to
geographic limits and time limits.

                    Adoption of a Dividend Reinvestment Plan
                    ----------------------------------------

     Proposed Amendment:  Section 3.4 shall be redesignated 3.4(b) and a new
     ------------------                                                     
subsection (a) shall be added as follows:

          3.4  VOLUNTARY CAPITAL CONTRIBUTIONS OF THE MEMBERS.
               ---------------------------------------------- 
    
          (a)  There is hereby established a dividend reinvestment plan for the
          Company pursuant to which any Unitholder, in the discretion of the
          President, his designee, or any other designee of the Managers, shall
          have the option, prior to the declaration of a dividend, to elect
          whether to receive such dividend in cash or in additional Units issued
          at the then current value of such Units. No sales load shall be 
          charged in connection with any additional Unit purchases made pursuant
          to the plan, nor shall any Unitholder be required to provide
          additional consideration in connection therewith.        
          

                                     xxxiv

     Explanation:  This amendment will enable the Company's Unitholders the
     -----------                                                           
option to reinvest dividends, an action which currently requires approval of the
Board of Managers or a Majority-in-Interest Vote of the Members on a case-by-
case basis.

               Indemnification of Managers, Officers and Others
               ------------------------------------------------

     Proposed Amendments:  Sections 11.3(c) and (d)
     -------------------                           
shall be amended as follows:

    
          (c) Subject to any limitations provided by the 1940 Act and this
     Agreement, the Company shall have the power and authority to advance
     expenses to any Indemnitee, and shall advance such expenses to the fullest
     extent permitted by law. Specifically, upon the submission of a claim to
     the Company for indemnification hereunder, the Company shall pay such claim
     from Company Assets within 45 days unless it has been determined prior to
     such time, and subject in any event to recoupment by the Company upon any
     later determination, (1) by a final decision on the merits by a court or
     other body of competent jurisdiction before whom the issue of entitlement
     to indemnification hereunder is brought that such Indemnitee is not
     entitled to indemnification hereunder or, (2) in the absence of such a
     decision, (i) by a Majority Vote of those Managers of the Company not
     parties to the Proceeding ("Disinterested Non-Party Managers") that the
     Indemnitee is not entitled to indemnification hereunder, or (ii) if such
     vote is not obtainable because of the lack of Disinterested Non-Party
     Managers, or even if obtainable, if such Majority so directs, independent
     legal counsel, in a written opinion, concludes that the Indemnitee is not
     entitled to indemnification hereunder because of Disabling Conduct. All
     requests for indemnification or advancement of expenses shall be
     accompanied by an undertaking by the claimant to repay the Company in the
     event such a determination is made and proof reasonably satisfactory to the
     Disinterested Non-Party Managers that the claimant is capable of meeting
     such undertaking.     
    
           (d)  The       

                                      xxxv
<PAGE>
 
    

     Company may also indemnify and advance expenses to other Persons providing
     services to the Company or any of its Affiliates to the full extent
     provided by law as if the Company were a corporation organized under the
     Delaware General Corporation Law, provided in either event that such
     advance or indemnification has been approved by a Majority of the Managers.
         

     Explanation:  This amendment is designed to clarify the previous
     -----------                                                     
indemnification provisions and to obligate the Company to indemnify its managers
and officers and advance their expenses to the fullest extent allowed by law.

                              ====================

                      LIMITED LIABILITY COMPANY AGREEMENT

                                      FOR

                     WHITEROCK PORTFOLIO INVESTORS, L.L.C.

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


                                  Dated as of
                               the Effective Date
                                 stated herein.
    
                         Restated with all Amendments
                       Made as of January 21, 1997      

     Finally, other conforming changes such as updating of the Table of Contents

be made, and the

                                     xxxvii
<PAGE>
 
Operating Agreement shall be regenerated in its entirety as so amended and
restated to date.

     Explanation:  The remaining amendments outlined above are designed to
     -----------                                                          
clarify the Operating Agreement and update changed factual information.  For
example, several terms defined in the main articles of the Operating Agreement
were not cross-referenced in the definitions section.  Other changes were needed
to reflect the resignation of Robert Gidel as the Company's Secretary and its
original contact person, and the recent election of the additional Managers.

                                   PROPOSAL 3

            ELECTION OF ADDITIONAL PERSONS TO THE BOARD OF MANAGERS;
                        RE-ELECTION OF CERTAIN MANAGERS

     The Board of Managers has approved for submission to the Unitholders Mr.
Craig Longfield and Mr. Dan Rosborough for election to fill the vacancies
created on the Board by the recent resignations of Messrs. Crandall, Wirkkala
and Lanz.  The Board has also approved submitting the names of Ms. Nori Gerardo
and Mr. William Peressini for re-election by the Unitholders at this time as
well.  Each nominee has indicated his or her willingness to serve if elected.
Each nominee will hold office until his or her death, Resignation, Removal or
Dissociation as a Member and until his or her successor is elected and
qualified.  Subject to adoption of Proposal 2(b)

                                    xxxviii
<PAGE>
 
above, a vote for the proposed slate of four Managers will also be deemed a vote
in favor of reducing the current number of Managers from five to four in
accordance with Section 4.2(b) of the Operating Agreement as it will be amended
pursuant to this proxy solicitation.

     Information on the business experience during the past five years of Mr.
Peressini is set forth in Proposal No. 1 above. Such information regarding the
business experience of Messrs. Longfield and Rosborough and Ms. Gerardo is set
forth below:

     Mr. Peressini is considered an "interested person" of the Company, as that
term is defined in Section 2(a)(19) of the Investment Company Act.  Messrs.
Longfield and Rosborough and Ms. Gerardo are not considered "interested persons"
of the Company.

     The Company's Board of Managers has no separate nominating, compensation or
audit committee, or any committee performing similar functions, although the
Board previously had designated Mr. Brian Wirkkala to serve as liaison for the
Board in connection with the services to be provided by the Company's
independent accountant. The Board as a whole acts in these capacities.

     As of December 16, 1996, all Managers and Officers of the Company as a
group owned approximately [1.2%] of the Company's outstanding securities.

     No per meeting attendance fees have been authorized for any of the
Managers.  For fiscal 1995 and 1996, no compensation was paid to any
"disinterested" Board member for attendance at any regularly scheduled meeting
of the Board.  The Company has no bonus, profit-sharing, pension or retirement
plan.

                                   PROPOSAL 4

             APPROVAL OF VARIOUS UNIT ISSUANCES AND UNIT TRANSFERS

     The Managers have determined it to be in the best interest of the Company
(1) to be able to accept additional Capital Commitments from certain of the
existing Members to the extent offered by such Members, (2) to approve the
transfer of any or all of Mr. Crandall's Units to Mr. Grayken, (3) to approve
the making of additional gifts by Brazos

Principal Genpar, L.P. ("Brazos") of Units purchased by it to those of its
employees or employees of affiliates who are already Members of the Company, and
(4) to approve the transfer of Units from each of Messrs. Wirkkala and Lanz, as
outgoing Managers, to each of Messrs. Longfield and Rosborough (the newly
elected Managers), respectively, if they so agree among themselves. By prior
board resolution and under the provisions of the amended Operating Agreement
discussed above, however, such actions can only be taken if approved by the
President and those Members holding more than 50 percent of the outstanding
Units of the Company. The Managers therefore request authorization from the
Members for the President or his designee to take the actions indicated above.

     With respect to the issuances of new Units, a vote for this proposal will
authorize the President to accept additional Capital Commitments on behalf of
the Company and its Managers from those Members indicated below, and thereafter
to call capital from any or all of such Members from time to time, but solely
for the purpose of fulfilling the Company's obligations with respect to its
investments as previously approved by the Managers (including its subscription
for a limited partner interest in the Lone Star Opportunity Fund, L.P.), and the
President's acceptance shall remain subject to the Company's receipt of a valid
Admission

Agreement or equivalent subscription document from each of the following
Members. In this regard, if approved by vote of the Unitholders, the President
or his designee may accept additional Capital Commitments in the following or
any lesser amounts from the Members listed below, and thereafter may act to call
capital from such persons from time to time, and shall cause the Company to
issue additional Units therefor on its books to the extent fully paid in cash:

     A vote in favor of this proposal shall also be a vote of approval of the

Grayken, and of Messrs. Wirkkala or Lanz's Units to Messrs. Rosborough and
Longfield, in either case in the discretion of the transferor and on such terms
as the transferor and transferee may agree amongst themselves, and to the
admission of Messrs. Rosborough and Longfield as Members of the Company, whether

gifts of any of the Units held by Brazos Principal Genpar, L.P. ("Brazos") from
time to time and whenever issued (including any Units newly issued pursuant to
the approvals requested above), in the sole discretion of Brazos, to any of
those persons previously identified to and approved by the Board of Managers by
Unanimous Written Consent dated as of December 22, 1995, each of whom is
currently a Member of the Company, and subject in either case to a determination
by the Company's Administrator that such actions are permitted under applicable
securities laws without adverse consequence to the Company or its Members.

                                 OTHER MATTERS

     The Board of Managers does not intend to present for action at the Meeting
any business other than the matters described in the Notice of Special Meeting,
and at the date of this Proxy Statement is not aware of any other matters that
properly may be presented for action at the Meeting.  If any other business not
described herein should properly be brought before the Meeting, or if any
procedural matters requiring a vote of Unitholders should arise at the Meeting,
the persons named as proxies or their substitutes will vote the Units

     The Company is not required, and does not intend, to hold annual or other
periodic meetings of Members except as required by the Investment Company Act.
The next meeting of Members will be held at such time as the Board of Managers
