On May 9, 2003, we offered to purchase the limited partnership units of Winthrop
Growth Investors 1 Limited Partnership upon the terms and subject to the
conditions of the offer to purchase of that date. This notice supplements the
information contained in the original offer to purchase and extends the offer
period. We are using the same defined terms in this supplement that we used in
the original offer to purchase.

WE ARE ISSUING THIS SUPPLEMENT TO YOU TO PROVIDE YOU ADDITIONAL INFORMATION
CONCERNING THE OFFER AND TO EXTEND THE OFFER PERIOD. WE URGE YOU TO READ THE
FOLLOWING PARAGRAPHS CAREFULLY. PLEASE READ THE OFFER TO PURCHASE, TOGETHER WITH
THIS SUPPLEMENT, FOR A DESCRIPTION OF OUR OFFER. QUESTIONS AND REQUESTS FOR
ADDITIONAL COPIES OF THE OFFER TO PURCHASE, THIS SUPPLEMENT, THE AMENDED
ACKNOWLEDGMENT AND AGREEMENT, OR THE AMENDED LETTER OF TRANSMITTAL MAY BE
DIRECTED TO THE INFORMATION AGENT AT (800) 461-2657.

Please take note of the following clarifications and supplements to the offer to
purchase:

EXTENSION OF TERM

         We have extended the term or our offer. The offer was scheduled to
expire on June 6, 2003, but has been extended to midnight, New York time on June
19, 2003. If you have not already done so, please remember that to accept our
offer, you must complete and return the enclosed amended acknowledgment and
agreement and related documents, as more fully described below, to us before
midnight, New York time on June 19, 2003. As of June 4, 2003, 282 units, or
1.10%, had been tendered to us in response to this offer.

MAXIMUM NUMBER OF UNITS TO BE ACCEPTED

         We are offering to purchase all outstanding limited partnership units
not held by us, subject to the conditions of the offer.

CONDITIONS OF THE OFFER

         Our original offer to purchase stated that we will not be required to
accept for payment and pay for units upon the occurrence of the conditions
specified in "The Offer--Section 17. Conditions of the Offer" or any event that
might reasonably be expected to result in such occurrence. The conditions of the
offer include the lack of any change that may be materially adverse or that may
have a material adverse effect. We will interpret all references to "that might
reasonably be expected," "which may have" or "which may be" to mean those events
that would be likely in the judgment of a reasonably prudent investor.



         The conditions set forth in our original offer to purchase include the
lack of any "extraordinary" change or material adverse change in the financial,
real estate or money markets or major equity security indices in the United
States. We will interpret "extraordinary" to mean materially adverse.

         The conditions also include the lack of certain events that might
affect "the benefits expected to be derived by us." We expect the benefits of
our offer to be economic benefits arising from the ownership of the tendered
units and the voting rights associated with those units.

         All conditions of the offer, other than those conditions that are
dependent upon receipt of necessary government approvals, must be satisfied or
waived in compliance with the securities laws and the tender offer rules. If
there is any question as to whether a condition is satisfied or waived, then we
will exercise due care to ensure that the unitholders receive prompt notice of
the failure of any condition.

         The paragraph following the conditions to the offer shall read as
follows:

                  The foregoing conditions are for our sole benefit and may be
         asserted by us regardless of the circumstances giving rise to such
         conditions or may be waived by us in whole or in part in our reasonable
         discretion. The failure by us at any time to exercise any of the
         foregoing rights shall not be deemed a waiver of any such right, the
         waiver of any such right with respect to any particular facts or
         circumstances shall not be deemed a waiver with respect to any other
         facts or circumstances and each right shall be deemed a continuing
         right which may be asserted at any time permitted by the securities
         laws. However, in interpreting these conditions, we shall at all times
         comply with our obligations under the securities laws, and where a
         condition is subject to our discretion or judgment, we shall act as a
         reasonably prudent investor would act.

FEDERAL INCOME TAX MATTERS

         The information provided in our original offer to purchase under "The
Offer--Section 6. Certain Federal Income Tax Matters" is our best understanding
of the tax consequences to a unitholder tendering units in this offer. However,
this information does not take into account the individual situation of any
unitholder and should not be considered a substitute for your tax advisor who is
more familiar with your personal circumstances. You should consult your tax
advisor regarding the United States federal, state, local and foreign tax
consequences of selling the interests in your partnership represented by your
units pursuant to our offer or a decision not to sell in light of your specific
tax situation.

INFORMATION CONCERNING YOUR PARTNERSHIP

         We are currently engaged in discussions regarding the acquisition of
the general partnership interests in your partnership that are owned or
controlled by Winthrop Financial Associates, A Limited Partnership, a Maryland
limited partnership, including those owned by Linnaeus-Lexington Associates
Limited Partnership, one of your partnership's general partners. There can be no
assurance that the acquisition will be consummated or how the acquisition will
be structured, and no specific allocation of value has been assigned to the
general partnership interests in your partnership.

INFORMATION CONCERNING AIMCO PROPERTIES

         More recent financial information regarding AIMCO Properties is now
available on our Quarterly Report on Form 10-Q for the quarter ended March 31,
2003, filed May 12, 2003 (particularly the management's discussion and analysis
of financial condition and results of operation). The summary financial
information provided in the original offer to purchase should be read in
conjunction with such financial statements.

ADDITIONAL INFORMATION

         Your partnership's prospectus, pursuant to which units in your
partnership were sold, indicated that your partnership was intended to be
self-liquidating and that it was anticipated that the partnership's properties
would be sold within five to seven years of their acquisition, provided market
conditions permit. . We do not currently expect that any of the partnership's
property will be sold in the foreseeable future.

         Section 9 of the offer to purchase contains an erroneous reference to
March 31, 2002. We determined our offer price on the basis of your partnership's
operating results for the quarter ended March 31, 2003.

         If you decide to accept our offer, you should complete and sign the
enclosed amended acknowledgment and agreement as instructed in the amended
letter of transmittal attached as Annex I, the terms of which will supersede the
acknowledgment and agreement delivered with the original offer materials. The
signed acknowledgment and agreement and any other documents required by the
letter of transmittal must be mailed or delivered to The Altman Group, Inc.,
which is acting as Information Agent in connection with our offer, at one of its

                                      -2-



not wish to withdraw your tender, then we will deem the terms of the amended
form of the letter of transmittal and amended form of the acknowledgment and
agreement enclosed in this mailing to supersede the terms of the previously
submitted letter of transmittal and acknowledgment and agreement. (The forms
differ only in that the amended form letter of transmittal clarifies that you
are not attesting to your understanding of the terms of the offer to purchase
and the form acknowledgment and agreement enclosed herewith does not request
that you acknowledge that you have "reviewed" the offering material .)

         The acknowledgment and agreement and any other documents required by
the letter of transmittal should be sent or delivered by each unitholder or such
unitholder's broker, dealer, bank, trust company or other nominee to the
Information Agent at its address set forth below.

Ladies and Gentlemen:

         The Signatory (the "Signatory") executing the Acknowledgment and
Agreement relating to the captioned offer (the "Acknowledgment and Agreement"),
which is enclosed, upon the terms and subject to the conditions set forth in the
offer to purchase, hereby and thereby tenders to the Purchaser the units set
forth in the box entitled "Description of Units Tendered" on the Acknowledgment
and Agreement, including all interests represented by such units (collectively,
the "Units"), at the consideration indicated in the offer to purchase as
supplemented or amended. Capitalized terms used herein but not otherwise defined
herein shall have the meanings ascribed thereto in such Acknowledgment and
Agreement.

         SUBJECT TO AND EFFECTIVE UPON ACCEPTANCE FOR CONSIDERATION OF ANY OF
THE UNITS TENDERED HEREBY AND THEREBY IN ACCORDANCE WITH THE TERMS OF THE OFFER
TO PURCHASE, THE SIGNATORY HEREBY AND THEREBY IRREVOCABLY SELLS, ASSIGNS,
TRANSFERS, CONVEYS AND DELIVERS TO, OR UPON THE ORDER OF, THE PURCHASER ALL
RIGHT, TITLE AND INTEREST IN AND TO SUCH UNITS TENDERED HEREBY AND THEREBY THAT
ARE ACCEPTED FOR PAYMENT PURSUANT TO THE OFFER TO PURCHASE, INCLUDING, WITHOUT
LIMITATION, (I) ALL OF THE SIGNATORY'S INTEREST IN THE CAPITAL OF THE
PARTNERSHIP, AND THE SIGNATORY'S INTEREST IN ALL PROFITS, LOSSES AND
DISTRIBUTIONS OF ANY KIND TO WHICH THE SIGNATORY SHALL AT ANY TIME BE ENTITLED
IN RESPECT OF HIS OWNERSHIP OF THE UNITS, INCLUDING, WITHOUT LIMITATION,
DISTRIBUTIONS IN THE ORDINARY COURSE, DISTRIBUTIONS FROM SALES OF ASSETS,
DISTRIBUTIONS UPON LIQUIDATION, WINDING-UP, OR DISSOLUTION, PAYMENTS IN
SETTLEMENT OF EXISTING OR FUTURE LITIGATION, DAMAGES PAID IN CONNECTION WITH ANY
EXISTING OR FUTURE LITIGATION AND ALL OTHER DISTRIBUTIONS AND PAYMENTS MADE FROM
AND AFTER THE EXPIRATION DATE, IN RESPECT OF THE UNITS TENDERED BY THE SIGNATORY
AND ACCEPTED FOR PAYMENT AND THEREBY PURCHASED BY THE PURCHASER; (II) ALL OTHER
PAYMENTS, IF ANY, DUE OR TO BECOME DUE TO THE SIGNATORY IN RESPECT OF THE UNITS,
UNDER OR ARISING OUT OF THE AGREEMENT AND CERTIFICATE OF LIMITED PARTNERSHIP OF
THE PARTNERSHIP (THE "PARTNERSHIP AGREEMENT"), OR ANY AGREEMENT PURSUANT TO
WHICH THE UNITS WERE SOLD (THE "PURCHASE AGREEMENT"), WHETHER AS CONTRACTUAL
OBLIGATIONS, DAMAGES, INSURANCE PROCEEDS, CONDEMNATION AWARDS OR OTHERWISE;
(III) ALL OF THE SIGNATORY'S CLAIMS, RIGHTS, POWERS, PRIVILEGES, AUTHORITY,
OPTIONS, SECURITY INTERESTS, LIENS AND REMEDIES, IF ANY, UNDER OR ARISING OUT OF
THE PARTNERSHIP AGREEMENT OR PURCHASE AGREEMENT OR THE SIGNATORY'S OWNERSHIP OF
THE UNITS, INCLUDING, WITHOUT LIMITATION, ANY AND ALL VOTING RIGHTS, RIGHTS OF
FIRST OFFER, FIRST REFUSAL OR SIMILAR RIGHTS, AND RIGHTS TO BE SUBSTITUTED AS A
LIMITED PARTNER OF THE PARTNERSHIP; AND (IV) ALL PAST, PRESENT AND FUTURE
CLAIMS, IF ANY, OF THE SIGNATORY WHETHER ON BEHALF OF THE PARTNERSHIP,
INDIVIDUALLY OR ON BEHALF OF A PUTATIVE CLASS (INCLUDING WITHOUT LIMITATION ANY
CLAIMS AGAINST LIMITED PARTNERS OF THE PARTNERSHIP, THE GENERAL PARTNER(S)
AND/OR ANY AFFILIATES THEREOF) UNDER, ARISING OUT OF OR RELATED TO THE
PARTNERSHIP AGREEMENT, THE PURCHASE AGREEMENT, THE SIGNATORY'S STATUS AS A
LIMITED PARTNER, THE TERMS OR CONDITIONS OF THE OFFER TO PURCHASE, THE
MANAGEMENT OF THE PARTNERSHIP, MONIES LOANED OR ADVANCED, SERVICES RENDERED TO
THE PARTNERSHIP OR ITS PARTNERS, OR ANY OTHER CLAIMS ARISING OUT OF OR RELATED
TO THE SIGNATORY'S OWNERSHIP OF UNITS IN THE PARTNERSHIP.

         NOTWITHSTANDING ANY PROVISION IN THE PARTNERSHIP AGREEMENT OR ANY
PURCHASE AGREEMENT TO THE CONTRARY, THE SIGNATORY HEREBY AND THEREBY DIRECTS THE
GENERAL PARTNER OF THE PARTNERSHIP TO MAKE ALL DISTRIBUTIONS AFTER THE PURCHASER
ACCEPTS THE TENDERED UNITS FOR PAYMENT TO THE PURCHASER OR ITS DESIGNEE. Subject
to and effective upon acceptance for payment of any Unit tendered hereby and
thereby, the Signatory hereby requests that the Purchaser be admitted to the
Partnership as a limited partner under the terms of the Partnership Agreement.
Upon request, the Signatory will execute and deliver additional documents deemed
by the Information Agent or the Purchaser to be necessary or desirable to
complete the assignment, transfer and purchase of Units tendered hereby and
thereby and will hold any distributions received from the Partnership after the
Expiration Date in trust for the benefit of the Purchaser and, if necessary,
will promptly forward to the Purchaser any such distributions immediately upon
receipt. The Purchaser reserves the right to transfer or assign, in whole or in
part,


                                Annex I - Page 2



from time to time, to one or more of its affiliates, the right to purchase Units
tendered pursuant to the offer to purchase, but any such transfer or assignment
will not relieve the Purchaser of its obligations under the offer to purchase or
prejudice the rights of tendering limited partners to receive payment for Units
validly tendered and accepted for payment pursuant to the offer to purchase.

         By executing the enclosed Acknowledgment and Agreement, the Signatory
represents that either (i) the Signatory is not a plan subject to Title I of the
Employee Retirement Income Security Act of 1974, as amended ("ERISA"), or
Section 4975 of the Internal Revenue Code of 1986, as amended (the "Code"), or
an entity deemed to hold "plan assets" within the meaning of 29 C.F.R. Section
2510.3-101 of any such plan, or (ii) the tender and acceptance of Units pursuant
to the offer to purchase will not result in a nonexempt prohibited transaction
under Section 406 of ERISA or Section 4975 of the Code.

         The Signatory recognizes that under certain circumstances set forth in
the offer to purchase, the Purchaser may not be required to accept for
consideration any or all of the Units tendered hereby. In such event, the
Signatory understands that any Acknowledgment and Agreement for Units not
accepted for payment may be returned to the Signatory or destroyed by the
Purchaser (or its agent). THIS TENDER IS IRREVOCABLE, EXCEPT THAT UNITS TENDERED
PURSUANT TO THE OFFER TO PURCHASE MAY BE WITHDRAWN AT ANY TIME PRIOR TO THE
EXPIRATION DATE OR ON OR AFTER JULY 3, 2003 IF UNITS VALIDLY TENDERED HAVE NOT
BEEN ACCEPTED FOR PAYMENT.

         THE SIGNATORY HAS BEEN ADVISED THAT THE PURCHASER IS AN AFFILIATE OF
THE GENERAL PARTNER OF THE PARTNERSHIP AND THE GENERAL PARTNER DOES NOT MAKE ANY
RECOMMENDATION AS TO WHETHER TO TENDER OR REFRAIN FROM TENDERING UNITS IN THE
OFFER TO PURCHASE. THE SIGNATORY HAS MADE HIS OR HER OWN DECISION TO TENDER
UNITS. THE SIGNATORY ALSO REPRESENTS AND WARRANTS THAT HE OR SHE WAS ADVISED TO
CONSULT AN ATTORNEY WITH RESPECT TO HIS OR HER DECISION WHETHER TO TENDER
HIS/HER INTEREST(s).

         The Signatory hereby and thereby represents and warrants for the
benefit of the Partnership and the Purchaser that the Signatory owns the Units
tendered hereby and thereby and has full power and authority and has taken all
necessary action to validly tender, sell, assign, transfer, convey and deliver
the Units tendered hereby and thereby and that when the same are accepted for
payment by the Purchaser, the Purchaser will acquire good, marketable and
unencumbered title thereto, free and clear of all liens, restrictions, charges,
encumbrances, conditional sales agreements or other obligations relating to the
sale or transfer thereof, and such Units will not be subject to any adverse
claims and that the transfer and assignment contemplated herein and therein are
in compliance with all applicable laws and regulations.

         All authority herein or therein conferred or agreed to be conferred
shall survive the death or incapacity of the Signatory, and any obligations of
the Signatory shall be binding upon the heirs, personal representatives,
trustees in bankruptcy, legal representatives, and successors and assigns of the
Signatory.

         The Signatory represents and warrants that, to the extent a certificate
evidencing the Units tendered hereby and thereby (the "original certificate") is
not delivered by the Signatory together with the Acknowledgment and Agreement,
(i) the Signatory represents and warrants to the Purchaser that the Signatory
has not sold, transferred, conveyed, assigned, pledged, deposited or otherwise
disposed of any portion of the Units, (ii) the Signatory has caused a diligent
search of its records to be taken and has been unable to locate the original
certificate, (iii) if the Signatory shall find or recover the original
certificate evidencing the Units, the Signatory will immediately and without
consideration surrender it to the Purchaser; and (iv) the Signatory shall at all
times indemnify, defend, and save harmless the Purchaser and the Partnership,
its successors, and its assigns from and against any and all claims, actions,
and suits, whether groundless or otherwise, and from and against any and all
liabilities, losses, damages, judgments, costs, charges, counsel fees, and other
expenses of every nature and character by reason of honoring or refusing to
honor the original certificate when presented by or on behalf of a holder in due
course of a holder appearing to or believed by the Partnership to be such, or by
issuance or delivery of a replacement certificate, or the making of any payment,
delivery, or credit in respect of the original certificate without surrender
thereof, or in respect of the replacement certificate.

partnership or others acting in a fiduciary or representative capacity, such
persons should, in addition to having their signatures guaranteed, indicate
their title in the Signature Box and must submit proper evidence satisfactory to

4.       TAX CERTIFICATIONS. The limited partner(s) tendering Units to the
         Purchaser pursuant to the Offer must furnish the Purchaser with the
         limited partner(s)' taxpayer identification number ("TIN") and certify
         as true, under penalties of perjury, the representations in Box 6 and
         Box 7 of the Acknowledgment and Agreement. By signing the Signature
         Box, the limited partner(s) certifies that the TIN as printed (or
         corrected) on Acknowledgment and Agreement in the box entitled
         "Description of Units Tendered" and the representations made in Box 6
         and Box 7 of the Acknowledgment and Agreement are correct. See attached
         Guidelines for Certification of Taxpayer Identification Number on
         Substitute Form W-9 for guidance in determining the proper TIN to give
         the Purchaser.

U.S. PERSONS. A limited partner that is a U.S. citizen or a resident alien
individual, a domestic corporation, a domestic partnership, a domestic trust or
a domestic estate (collectively, "U.S. Persons"), as those terms are defined in
the Code, should follow the instructions below with respect to certifying Box 6
and Box 7 of the Acknowledgment and Agreement.

BOX 6 - SUBSTITUTE FORM W-9.

Part (i), Taxpayer Identification Number -- Tendering limited partners must
certify to the Purchaser that the TIN as printed (or corrected) on the
Acknowledgment and Agreement in the box entitled "Description of Units Tendered"
is correct. If a correct TIN is not provided, penalties may be imposed by the
Internal Revenue Service (the "IRS"), in addition to the limited partner being
subject to backup withholding.

Part (ii), Backup Withholding -- In order to avoid 30% Federal income tax backup
withholding, the tendering limited partner must certify, under penalty of
perjury, that such limited partner is not subject to backup withholding. Certain
limited partners (including, among others, all corporations and certain exempt
non-profit organizations) are not subject to backup withholding. Backup
withholding is not an additional tax. If withholding results in an overpayment
of taxes, a refund may be obtained from the IRS.

When determining the TIN to be furnished, please refer to the following as a
guide:

Individual accounts - should reflect owner's TIN.
Joint accounts - should reflect the TIN of the owner whose name appears first.



                                      -2-



Trust accounts - should reflect the TIN assigned to the trust.
IRA custodial accounts - should reflect the TIN of the custodian (not necessary
to provide).
Custodial accounts for the benefit of minors - should reflect the TIN of the
minor.
Corporations, partnership or other business entities - should reflect the TIN
assigned to that entity.

By signing the Signature Box, the limited partner(s) certifies that the TIN as
printed (or corrected) on the front of the Acknowledgment and Agreement is
correct.

BOX 7 - FIRPTA AFFIDAVIT -- Section 1445 of the Code requires that each limited
partner transferring interests in a partnership with real estate assets meeting
certain criteria certify under penalty of perjury the representations made in
Box 7, or be subject to withholding of tax equal to 10% of the consideration for
interests purchased. Tax withheld under Section 1445 of the Code is not an
additional tax. If withholding results in an overpayment of tax, a refund may be
claimed from the IRS.

FOREIGN PERSONS -- In order for a tendering limited partner who is a Foreign
Person (i.e., not a U.S. Person, as defined above) to qualify as exempt from 30%
backup withholding, such foreign limited partner must submit a statement, signed
under penalties of perjury, attesting to that individual's exempt status. Forms
for such statements can be obtained from the Information Agent.

5.       VALIDITY OF ACKNOWLEDGMENT AND AGREEMENT. All questions as to the
         validity, form, eligibility (including time of receipt) and acceptance
         of an Acknowledgment and Agreement and other required documents will be
         determined by the Purchaser and such determination will be final and
         binding. The Purchaser's interpretation of the terms and conditions of
         the Offer (including these Instructions for the Acknowledgment and
         Agreement) will be final and binding. The Purchaser will have the right
         to waive any irregularities or conditions as to the manner of
         tendering. Any irregularities in connection with tenders, unless
         waived, must be cured within such time as the Purchaser shall
         determine. The Acknowledgment and Agreement will not be valid until any
         irregularities have been cured or waived. Neither the Purchaser nor the
         Information Agent are under any duty to give notification of defects in
         an Acknowledgment and Agreement and will incur no liability for failure
         to give such notification.

6.       ASSIGNEE STATUS. Assignees must provide documentation to the
         Information Agent which demonstrates, to the satisfaction of the
         Purchaser, such person's status as an assignee.

7.       TRANSFER TAXES. The amount of any transfer taxes (whether imposed on
         the registered holder or such person) payable on account of the
         transfer to such person will be deducted from the consideration unless
         satisfactory evidence of the payment of such taxes or exemption
         therefrom is submitted.

8.       SPECIAL PAYMENT AND DELIVERY INSTRUCTIONS. If consideration is to be
         issued in the name of a person other than the person signing the
         Signature Box of the Acknowledgment and Agreement or if consideration
         is to be sent to someone other than such signer or to an address other
         than that set forth on the Acknowledgment and Agreement in the box
         entitled "Description of Units Tendered," the appropriate boxes on the
         Acknowledgment and Agreement must be completed.

IRS uses the numbers for identification purposes. Payers must be given the
numbers whether or not recipients are required to file a tax return. Payers must
generally withhold 30% of taxable interest, dividend, and certain other payments
to a payee who does not furnish a correct taxpayer identification number to a
payer. Certain penalties may also apply.

         PENALTIES

         (1) PENALTY FOR FAILURE TO FURNISH TAXPAYER IDENTIFICATION NUMBER --
If you fail to furnish your correct taxpayer identification number to a payer,
you are subject to a penalty of $50 for each such failure unless your failure is
due to reasonable cause and not to willful neglect.

         (2) CIVIL PENALTY FOR FALSE INFORMATION WITH RESPECT TO WITHHOLDING --
If you make a false statement with no reasonable basis that results in no
imposition of backup withholding, you are subject to a penalty of $500.

         (3) CRIMINAL PENALTY FOR FALSIFYING INFORMATION -- Willfully
falsifying certifications or affirmations may subject you to criminal penalties
including fines and/or imprisonment.
