                                 AMENDMENT NO. 1

        This Amendment No. 1 amends and supplements the Tender Offer Statement
on Schedule TO (the "Schedule TO") by Equity Resource Dover Fund, Limited
Partnership, a Massachusetts limited partnership, Eggert Dagbjartsson, its
general partner and Equity Resource Investments LLC, its manager (collectively
the "Purchaser") to purchase 50 units (the "Units") of limited partnership
interests in 1999 Broadway Associates Limited Partnership, a Delaware limited
partnership (the "Partnership"), at $10,000 for each Unit, net to the seller in
cash, without interest, less the amount of any distributions declared or paid
from any source by the Partnership with respect to the Units after April 20,
2005 (without regard to the record date), upon the terms and subject to the
conditions set forth in the Offer to Purchase (the "Offer to Purchase") and in
the related Agreement of Sale, copies of which are attached hereto as Exhibits
(a)(l) and (a)(3) (which are herein collectively referred to as the "Offer").
The information in the Offer to Purchase, including all schedules and annexes
thereto, is hereby expressly incorporated herein by reference in response to all
the items of this Statement, except as otherwise set forth below.

        ITEMS 1, 4 AND 12

        Items 1, 4 and 12 of the Schedule TO/T, which incorporate by reference
the information contained in the Offer to Purchase, are hereby amended as
follows:

ITEM 1--SUMMARY TERM SHEET

    Question 4 of Summary Term Sheet is amended in its entirety to read as
follows:

    "How much are you offering to pay for my securities and what is the form of
    payment? Will I have to pay fees or commissions? Dover Fund is offering to
    purchase 50 Units ("Units") of limited partnership interests in 1999
    Broadway Associates Limited Partnership, a Delaware limited partnership (the
    "Partnership"). Dover Fund is offering to pay a purchase price of $10,000
    for each Unit, to the seller in cash, without interest, less the amount of
    any distributions declared or paid from any source by the Partnership with
    respect to the Units after April 20, 2005 (without regard to the record
    date), upon the terms and subject to the conditions set forth in this Offer
    to Purchase (the "Offer to Purchase") and in the Agreement of Sale, as each
    may be supplemented or amended from time to time (which together constitute
    the "Offer"). The Purchaser will pay all transfer fees charged by the
    general partner of the Partnership. If any distributions are declared or
    paid from any source by the Partnership while the Offer is open, the
    Purchaser will amend the Offer to disclose the event and to extend the Offer
    so that 10 business days remain in the offer prior to the expiration of the
    Offer. If you tender your Units in the Offer and you were not entitled to
    receive any distribution declared or paid from any source by the Partnership
    with respect to your Units after April 20, 2005, the amount paid to you in
    the Offer will not be reduced by the amount of any distribution you were not
    entitled to receive. Limited partners who hold their units in a brokerage
    account or in trust may be required to pay commissions or similar payments
    if they tender their Units. Limited partners should consult their advisors
    concerning such brokerage fees, commissions or similar expenses associated
    with the tender their Units."

    Question 7 of Summary Term Sheet is amended in its entirety to read as
follows:

    "Can the offer be extended or amended and under what circumstances? Yes, we
    may elect to extend the offer in order to extend the period of time during
    which the offer is open and/or to amend the offer in any respect (including,
    without limitation, by increasing or decreasing the offer price). If the
    Offer is amended with less than 10 business days remaining in the offering
    period, the Offer will be extended to give limited partners at least 10
    business days following the filing of the amendment to consider the amended
    offer. If you do not tender your Units during the initial

                                        2


    offering period, you will not have the opportunity to accept the offer. See
    'THE OFFER--Section 5--Extension of Tender Period; Termination; Amendment.""

ITEM 4--TERMS OF THE TRANSACTION

    Paragraph 1 of "The Offer" is amended to read as follows:

    "Equity Resource Dover Fund, Limited Partnership, a Massachusetts limited
    partnership, Eggert Dagbjartsson, its general partner and Equity Resource
    Investments LLC, its manager (collectively "Dover Fund" or the "Purchaser"),
    hereby offers to purchase 50 Units ("Units") of limited partnership
    interests in 1999 Broadway Associates Limited Partnership, a Delaware
    limited partnership (the "Partnership"). Dover Fund is offering to pay a
    purchase price of $10,000 for each Unit, to the seller in cash, without
    interest, less the amount of any distributions declared or paid from any
    source by the Partnership with respect to the Units after April 20, 2005
    (without regard to the record date), upon the terms and subject to the
    conditions set forth in this Offer to Purchase (the "Offer to Purchase") and
    in the Agreement of Sale, as each may be supplemented or amended from time
    to time (which together constitute the "Offer".) Neither Dover Fund, Equity
    Resource Investments LLC, Dover Fund's manager nor Eggert Dagbjartsson,
    Dover Fund's general partner is an affiliate of the Partnership or the
    general partner of the Partnership. The Units sought to be purchased
    pursuant to the Offer represent, to the best knowledge of the Purchaser,
    approximately 10.9% of all Units outstanding as of the date of the Offer."

    Paragraph 6 of "The Offer-Introduction" is amended to read as follows:

    "No Selling Commissions Units sold in the informal market "matching service"
    usually require payment of a selling commission of the greater of $200 or
    8.75%. If you accept the Offer, you will not pay any selling commission.
    Limited partners who hold their units in a brokerage account or in trust
    may, however, be required to pay commissions or similar payments if they
    tender their Units. Limited partners should consult their advisors
    concerning such brokerage fees, commissions or similar expenses associated
    with the tender their Units."

    Paragraph 9 of "The Offer-Risk Factors" is amended to read as follows:

    "The Purchaser has not engaged a depository to hold tendered units until
    payment. A depository is an independent agent who holds tendered units until
    payment. The Purchaser has not engaged a depository for the Offer and the
    transfer of units will not be dependent on a depository's determination that
    payment has been made. The primary risk associated with the Purchaser's
    decision to not engage a depository is that the Purchaser could assume
    ownership of tendered units before all terms of the Offer (including payment
    for the Units) are complete since it is the Purchaser and not the
    independent Depository who will be responsible for the transfer of Units and
    payment to those Limited Partners who tender Units. The Purchaser will not,
    however, accept Units tendered under the Offer until the Offer has expired
    and all conditions of the Offer have either been satisfied or waived."

    "The Offer-Section 1-Terms of the Offer" is amended in its entirety to read
as follows:

    "Upon the terms and subject to the conditions of the Offer, the Purchaser
    will accept for payment and pay for up to 50 Units that are validly tendered
    on or prior to the Expiration Date (as defined below). The term "Expiration
    Date" means 12:00 midnight, Eastern Time, on May 20, 2005, unless the
    Purchaser extends the period of time for which the Offer is open, in which
    event the term "Expiration Date" shall mean the latest date on which the
    Offer, as so extended by the Purchaser, shall expire.

                                        3


    The Offer is conditioned on satisfaction of certain conditions. See
    "Offer--Section 15--Certain Conditions of the Offer," which sets forth in
    full the conditions of the Offer. The Purchaser will not be required to
    accept for payment or to pay for any Units tendered, and may amend or
    terminate the Offer if the Agreement of Sale is not properly completed and
    duly executed.

    Purchaser reserves the right (but shall not be obligated) to waive any or
    all of these conditions. If any or all of those conditions have not been
    satisfied or waived by the Expiration Date, Purchaser reserves the right
    (but shall not be obligated) to (i) terminate the Offer and return all
    tendered Units to tendering Limited Partners, (ii) waive all of the
    unsatisfied conditions and, subject to complying with applicable rules and
    regulations of the SEC, purchase all Units validly tendered, (iii) extend
    the Offer and, subject to the right of Limited Partners to withdraw Units
    until the Expiration Date, retain the Units that have been tendered during
    the period or periods for which the Offer is extended or (iv) otherwise
    amend the Offer. If any material conditions are waived, the Purchaser will
    amend the Offer to disclose its waiver. If the amendment is filed with less
    than ten (10) business days remaining in the Offer, the Purchaser will
    extend the offer giving limited partners at least ten (10) business days
    following the amendment to consider the amended offer."

    "The Offer-Section 2-Proration; Acceptance for Payment and Payment for
Units" is amended in its entirety to read as follows:

    "If fewer than 50 Units are validly tendered and not properly withdrawn
    prior to the Expiration Date, the Purchaser, upon the terms and subject to
    the conditions of the Offer, will accept for payment all of those Units so
    tendered.

    The Purchaser will pay for shares properly tendered promptly after the
    expiration of the offer in accordance with Rule 14e-l(c).

    If more than 50 Units are validly tendered and not properly withdrawn on or
    prior to the Expiration Date, the Purchaser, upon the terms and subject to
    the conditions of the Offer, will accept for payment 50 Units so tendered,
    on a pro rata basis, with appropriate adjustments to avoid tenders of
    fractional Units. As a result, if Units are purchased on a prorated basis,
    the total number of Units accepted for payment will be based on the highest
    number up to 50 Units under which Units can be accepted without the tender
    of fractional Units.

    In the event that proration is required, the Purchaser will determine the
    precise number of Units to be accepted and will announce the final results
    of proration as soon as practicable, but in no event, later than five (5)
    business days following the Expiration Date. A letter announcing the final
    results of proration will be mailed to all tendering limited partners and a
    press release announcing the final results of proration will be released.
    Purchaser will not pay for any Units tendered until after the final results
    of proration have been determined.

    If, prior to the Expiration Date, the Purchaser increases the Offer Price,
    the increased Offer Price will be paid for all Units accepted for payment
    pursuant to the Offer, whether or not those Units were tendered prior to
    such increase."

    Paragraph 1 of "The Offer-Section 6-Tax Consequences is amended to read as
follows:

    "The following is a summary of the federal income tax consequences of a sale
    of Units pursuant to the Offer based on the fact that the Partnership is a
    partnership for federal income tax purposes and not a "publicly traded
    partnership" as defined in Section 7704 of the Internal Revenue Code of
    1986, as amended (the "Code"). "Publicly traded partnerships", as defined in
    Section 7704, are partnerships that are traded on an established securities
    market or readily tradable on a secondary market. Publicly traded
    partnerships are taxed as corporations. "

                                        4


    "The Offer-Section 7-Purpose and Effects of the Offer" is amended in its
entirety to read as follows:

    "The Purchaser is making the Offer for investment purposes with a view
    towards making a profit. Its intent is to acquire Units at a discount to the
    value that it might ultimately realize from owning Units. No independent
    party has been retained by the Purchaser to evaluate or render any opinion
    with respect to the fairness of the Offer Price and no representation is
    made as to the fairness of the Offer Price. In establishing the Offer Price,
    the Purchaser primarily consider two factors: prices previously paid for
    Units and the Property's current potential value.

    Over the past twelve months, the Purchaser has acquired 5 Units in the
    Partnership at a price of $5,000 per Unit. Prior to that, an affiliate of
    the Purchaser acquired 23.5 Units through a November 21, 2001 tender offer.
    It acquired those Units at a price of $20,000 per Unit. These are the only
    trades of Units that the Purchaser is aware of over that period. The change
    in price between the 2001 tender offer and the acquisition of Units in the
    past twelve months was based on the market weakness and tenant issues
    discussed in the Partnership's recent financial statements and in section 10
    of the Offer. While many of these issues still exist, recent operating
    improvements, including an increase in both rental income and occupancy, led
    the Purchaser to reanalyze the Partnership.

    In this analysis, the Purchaser attempted to estimate the value of Units.
    The Partnership owns an interest in a 42-story, 635,737 (net rentable)
    square foot office tower (the "Office Tower") and an eight-story parking
    garage (the "Garage") located in downtown Denver, Colorado. The Office Tower
    and Garage are collectively known as the "Property". According to the
    Partnership's most recent financial statements, the Property has a heavy
    concentration of tenants in the technology and telecommunications
    industries, both of which have been experiencing severe decline. Notably,
    Lucent Technologies, which leases 12% of the Property, has vacated its space
    and is marketing it for sublease. Lucent's lease is scheduled to expire
    December 2005, at which time the Partnership will be required to re-tenant
    the space.

    Because of the decline in the Denver real estate market, the Partnership may
    be unable to find a new tenant or tenants at rental rates that will generate
    cash flow sufficient to meet its debt service obligations, in which case the
    Partnership may be required to raise additional capital or sell the
    property. This risk makes it difficult to establish a market value for
    Units, especially when you consider that opportunities to resell Units and
    mitigate any subsequent decline in value (should a decline occur) are
    limited given the illiquid nature of limited partnership units (see below).
    The method the Purchaser ultimately relied on in establishing the Offer
    Price was based on an estimate of the Property's value using the recent sale
    of a property located at 1700 Broadway in Denver (the "Comparison
    Property"). The Comparison Property is a high-rise office tower located
    three blocks from the Property. The Comparison Property was built in 1954
    (approximately thirty years prior to the Property), but has undergone an
    extensive renovation.

    The Comparison Property was sold in June 2004 at a price of $87 per square
    foot. The Purchaser multiplied this per square foot sale price by the
    635,737 square feet of rentable space in the Office Tower to come up with a
    property value of $55,309,119. The Purchaser assigned no additional value to
    the Garage since spaces in the Garage are assigned to tenants of the Office
    Tower and generate no additional revenue. In establishing the Offer Price,
    the Purchaser deducted 3% selling commissions from the $55,309,119 value to
    come up with a net property value of $53,649,845. It then added other assets
    of $5,506,000 and deducted liabilities of $50,946,000 (taken from the
    Partnership's most recent 10-K) to come up with a $8,209,548 net asset value
    (NAV) for the Partnership. Limited partners own a 99% economic interest in
    the Partnership. There are 460 limited partnership Units. Based on this
    ownership interest, the Partnership NAV of $8,209,548 translates into a per
    Unit NAV of $17,847.

    The Purchaser chose the Comparison Property method in establishing the Offer
    Price based on its belief that the risks associated with owning Partnership
    Units are related primarily to overall weakness in the Denver office market
    (in 2004, the Downtown Denver market experienced negative absorption of
    approximately 256,000 square feet of space). Since the Purchaser believes

                                        5


    that it is market weakness and not weakness specific to the Property that is
    causing the risks associated with owning Units, the Purchaser believes that
    recent property sales best take the market weakness into account. The
    Comparison Property was sold in June 2004. That is the most recent sale of a
    high-rise office building in the Denver market that the Purchaser is aware
    of. Though previous sales generated higher prices per square foot, the fact
    that the sale of the Comparison Property is the most recent sale along with
    the fact that the Comparison Property is located in close proximity to the
    Property, the Purchaser believes it is appropriate to use the Comparison
    Property sale price in estimating the NAV of Units in the Partnership.

    Limited partners should remember that this NAV figure is based on
    assumptions that if changed, would alter the value of Units. The Purchaser
    used the sale price of the Comparison Property in determining the offer
    price based solely on its proximity to the Property and the fact that its
    sale is the most recent sale that the Purchaser is aware of. Using the same
    approach but a different sale price would result in a different net asset
    value for Units. Additionally, using a different valuation approach would
    also result in a different net asset value for Units. For example, the
    Property's 2004 net operating income was $6,018,000 (calculated by deducting
    operating expenses of $5,578,000 for income of $11,596,000). Using a direct
    capitalization approach, applying a 9% cap rate to this 2004 net operating
    income and deducting 3% selling commissions would result in an NAV of
    $42,219 per Unit. Applying the same approach to the Property's 2004 net
    operating income adjusted to reflect potential lost revenue through lease
    terminations in 2005 would result in an NAV of ($977). The Purchaser used a
    9% cap rate in these direct capitalization approached based on its own
    analysis and understanding of historical cap rate in office markets like the
    Denver office market.

    In determining its offer price of $10,000 per unit, the Purchaser applied a
    43% illiquidity discount to the $17,847 per Unit NAV. Applying an
    illiquidity discount is standard for real estate limited partnerships.
    According to the Direct Investments Spectrum, a national reporting service
    covering limited partnerships, the average annual discounts applied to real
    estate limited partnership since 1992 have ranged from 25% to 44%. The
    Purchaser chose an illiquidity discount at the top of the average annual
    range of discounts primarily because of the risks discussed above. Other
    measures of value may be relevant to a Limited Partner, and all Limited
    Partners are urged to carefully consider all of the information contained in
    the Offer to Purchase and Agreement of Sale and to consult with their own
    advisors (tax, financial, or otherwise) in evaluating the terms of the Offer
    before deciding whether to tender Units. The Offer is being made as a
    speculative investment by the Purchaser based on its belief that there is
    inherent underlying value in the assets of the Partnership. The purpose of
    the Offer is to allow the Purchaser to benefit to the greatest extent
    possible from any one or a combination of the following:

    .   any cash distributions, whether those distributions are classified as a
    return on, or a return of, capital, from the operations in the ordinary
    course of the Partnership;

    .   any distributions of net proceeds from the sale of assets by the
    Partnership;

    .   any distributions of net proceeds from the liquidation of the
    Partnership;

    .   any cash from any redemption of the Units by the Partnership, and

    .   any proceeds that may be received from any lawsuit brought by the
    Limited Partners, which lawsuit relates to the Partnership or its General
    Partner (the Purchaser is not aware of any lawsuit at this time and is not
    planning that action in the future).

    Price Range of Units; Lack of Public Market. At present, privately
    negotiated sales and sales through intermediaries (e.g., through the trading
    system operated by the American Partnership Board, which publishes sell
    offers by holders of Units) are the only means available to a Limited
    Partner to liquidate an investment in Units (other than by accepting the
    Offer) because the Units

                                        6


    are not listed or traded on any national securities exchange or quoted on
    NASDAQ. The Purchaser and its affiliates have purchased 5 Units in the
    Partnership in the past twelve months."

    The final paragraph of "The Offer-Section 10- Certain Information Concerning
    the Partnership" is amended to read as follows:

    "Other Information. The Partnership is subject to the reporting requirements
    of the Exchange Act and accordingly is required to file reports and other
    information with the SEC relating to its business, financial results and
    other matters. These reports and other documents may be inspected at the
    SEC's Public Reference Section, Room 1024, 450 Fifth Street, N.W.,
    Washington, D.C. 20549, where copies may be obtained at prescribed rate.
    Copies should be available by mail upon payment of the SEC's customary
    charges by writing to the SEC's principal offices at 450 Fifth Street, N.W.,
    Washington, D.C. 20549. The SEC also maintains a web site that contains
    reports, proxy and other information filed electronically with the SEC, the
    address of which is http://www.sec.gov. These reports and other documents
    are no longer available at the regional offices of the SEC."
