                                  COMMON STOCK
                               ------------------
 
    This Prospectus relates to the offer and sale by the holders thereof (the
"Selling Stockholders"), of 4,840,927 common stock, par value $.001 per share
(the "Common Stock"), of Ultrafem, Inc. ("Ultrafem" or the "Company") including
3,722,552 shares issuable upon conversion or exercise of certain outstanding
securities convertible into or exercisable for shares of Common Stock. (The
shares of Common Stock offered hereby are sometimes referred to herein as the
"Shares"). The Company's Common Stock is quoted on the Nasdaq National Market
under the trading symbol "UFEM." On May 15, 1997, the last reported sales price
for the Common Stock on the Nasdaq National Market was $14 5/8 per share. See
"Price Range of Common Stock."
 
    Subject to certain agreed upon lock-up periods more fully described below,
the Shares may be sold from time to time by the Selling Stockholders directly,
or through agents designated from time to time or through dealers or
underwriters also to be designated, on terms to be determined at the time of
sale. To the extent required, the specific Shares to be sold, the names of the
Selling Stockholders, the purchase price, the public offering price, the names
of any such agents, dealers or underwriters and any applicable commission or
discount with respect to a particular offer will be set forth in an accompanying
Prospectus supplement (or, if required, a post-effective amendment to the
Registration Statement of which this Prospectus forms a part). The distribution
of the Shares may be effected in one or more transactions that may take place on
the Nasdaq National Market or the over-the-counter market, including ordinary
broker's transactions, privately negotiated transactions or through sales to one
or more dealers for resale of such securities as principals, at market prices
prevailing at the time of sale, at prices related to such prevailing market
prices or at negotiated prices. Usual and customary or specifically negotiated
brokerage fees, commissions or discounts may be paid by the Selling Stockholders
in connection with such sales. Certain Selling Stockholders have agreed to
effect such sales through Hampshire Securities Corporation ("Hampshire"), one of
the underwriters that has previously underwritten public offerings of Common
Stock by the Company. See "Plan of Distribution."
 
    The Selling Stockholders and intermediaries through whom the Shares are sold
may be deemed "underwriters" within the meaning of the Securities Act of 1933,
as amended (the "Securities Act"), with respect to the Shares, and any profits
realized or commissions received may be deemed underwriting compensation. The
Company has agreed to indemnify the Selling Stockholders against certain
liabilities, including liabilities under the Securities Act.
 
    The Company will not receive any of the proceeds from the sale of Shares
offered hereby. Expenses of this Offering, estimated at $50,000, are payable by
the Company. The aggregate proceeds to the Selling Stockholders from the sale of
the Shares will be the purchase price of the Shares sold, less the aggregate
underwriting fees, discounts and commissions, if any. See "Selling
Stockholders."
 
    THE SHARES OFFERED HEREBY ARE SPECULATIVE AND INVOLVE A SUBSTANTIAL DEGREE
OF RISK. PROSPECTIVE INVESTORS SHOULD CAREFULLY READ THE FACTORS SET FORTH UNDER

                                  RISK FACTORS
 
    IN ADDITION TO THE OTHER INFORMATION INCLUDED IN, OR INCORPORATED BY
REFERENCE INTO, THIS PROSPECTUS, THE FOLLOWING RISK FACTORS SHOULD BE CONSIDERED
CAREFULLY IN EVALUATING THE COMPANY AND ITS BUSINESS BEFORE PURCHASING THE
SHARES OF COMMON STOCK OFFERED HEREBY. PROSPECTIVE INVESTORS ARE CAUTIONED THAT
THE STATEMENTS IN THIS PROSPECTUS THAT ARE NOT DESCRIPTIONS OF HISTORICAL FACTS
MAY BE FORWARD-LOOKING STATEMENT. SUCH STATEMENTS ARE BASED ON MANY ASSUMPTIONS
AND ARE SUBJECT TO RISKS AND UNCERTAINTIES. ACTUAL RESULTS COULD DIFFER
MATERIALLY FROM THE RESULTS DISCUSSED IN THE FORWARD LOOKING STATEMENTS DUE TO A
NUMBER OF FACTORS, INCLUDING, BUT NOT LIMITED TO, THOSE IDENTIFIED BELOW.
 
HISTORY OF LOSSES
 
    From the Company's inception in March 1990 through June 30, 1996, the
Company had not generated any revenue, and has only recently begun generating
revenue. Revenues to date have been limited. Through December 1996, the Company
has expended more than $33.9 million for, among other things, marketing,
research and development activities, engineering and design of fully automated
manufacturing systems, clinical testing, meeting domestic and international
regulatory requirements, domestic and international applications for patent
protection, applications for domestic trademark protection, and market research.
The Company may encounter difficulties experienced by companies which have only
recently begun generating revenues, many of which may be beyond the Company's
control, such as unanticipated problems and costs related to marketing of the
Company's first commercial product, INSTEAD-Registered Trademark-.
INSTEAD-Registered Trademark- is a feminine protection product which collects,
rather than absorbs menstrual fluid, and is based on the Company's proprietary
SoftCup Technology-Registered Trademark-. Management expects to continue
incurring operating losses for the foreseeable future, until such time as the
Company derives significant revenues from the sale of
INSTEAD-Registered Trademark-. Sales of INSTEAD-Registered Trademark- commenced
in the Fall of 1996. There can be no assurance that the Company will be
profitable. See "Need for Additional Financing for Unforeseen Risks."
 
DEPENDENCE ON SINGLE PRODUCT
 
    The Company's future profitability initially depends primarily on the
successful commercialization of INSTEAD-Registered Trademark- as an alternative
to currently available feminine protection products. Should the introduction of
INSTEAD-Registered Trademark- be unsuccessful for any reason, there would be a
material adverse effect on the Company's business, financial condition and
results of operation. See "-- Risks Associated with Research and Development for
Other Applications of the SoftCup Technology."
 
NEED FOR ADDITIONAL FINANCING FOR UNFORESEEN RISKS
 
    The Company believes that the level of financial resources available to it
is an important factor in its ability to achieve the marketing and distribution
of INSTEAD-Registered Trademark- and in its ability to develop and eventually
bring medical products to market. If the Company is unable to raise additional
capital or arrange satisfactory working capital or additional equity financing,
the Company may be unable to complete the distribution of
INSTEAD-Registered Trademark- into the full United States market. Also, the
Company may require additional financing if unforeseen risks are encountered.
Additional financings may require the issuance of new equity securities, and
there can be no assurance that the Company will be able to obtain working
capital or additional financing at a favorable rate, if at all. See "--Risks
Associated with Research and Development for Other Applications of the SoftCup
Technology."
 
LACK OF MANUFACTURING EXPERIENCE; NEED TO ACHIEVE ECONOMIES OF SCALE AND LIMITED
  MANUFACTURING RESOURCES
 
    The Company has only limited experience in manufacturing quantities of
INSTEAD-Registered Trademark- for the commercial market and has not yet
manufactured INSTEAD-Registered Trademark- on a cost-efficient basis. There can
be no
 
                                       5
<PAGE>
assurance that the Company will be able to manufacture quantities of
INSTEAD-Registered Trademark- for the commercial market on a cost efficient
basis, if at all. In the future the Company will be required to increase the
quantity of units it can produce, reduce per-unit manufacturing costs and
related marketing expenses and achieve high quality standards in order to
successfully market INSTEAD-Registered Trademark- on a commercial scale
throughout the full United States market. These criteria will only be satisfied
if the Company is able to either enhance significantly its existing production
capabilities or enter into arrangements with third parties capable of
manufacturing INSTEAD-Registered Trademark- on a cost-efficient basis. If the
Company encounters production difficulties or delays, including problems
involving production yield, quality control and assurance or supplies or
components, there could be a material adverse effect on the Company's business,
financial condition and results of operations. See "--History of Losses."
 
MARKETING RISKS; UNCERTAINTY OF CONSUMER ACCEPTANCE
 
    The Company has incurred, and expects to continue to incur, substantial
marketing expense in launching INSTEAD-Registered Trademark- into the United
States market. The marketing risks that the Company may encounter are compounded
by the unique nature of INSTEAD-Registered Trademark-. Because
INSTEAD-Registered Trademark- is fundamentally different from nearly all
commercially available forms of feminine protection, successful introduction of
INSTEAD-Registered Trademark- will face several obstacles, including a change in
established personal hygiene regimen and educating potential consumers on how to
use INSTEAD-Registered Trademark-. Furthermore, the Company will be competing
with other products which are already familiar to the target audience, and the
Company will be required to incur substantial marketing expense in order to
introduce INSTEAD-Registered Trademark- to consumers. There can be no assurance
that the Company will develop an effective marketing or advertising campaign to
overcome these obstacles. See "--Risks Associated with Potential Competitive
Response."
 
NECESSITY OF REGULATORY CLEARANCES TO MARKET
 
    The production and distribution of INSTEAD-Registered Trademark- are subject
to regulation in the United States and other countries in which
INSTEAD-Registered Trademark- may be sold. In 1993, the Food and Drug
Administration (the "FDA") cleared the Company's pre-market notification
submission under Section 510(k) of the Federal Food, Drug, and Cosmetic Act of
1938, as amended (the "FDCA"). The FDA's clearance of this notification enables
the Company to market INSTEAD-Registered Trademark- in the United States and to
export it overseas subject to the general controls provisions of the FDCA.
Subsequent to FDA clearance of this notification submission, certain
modifications, which the Company believes are minor, were made in the materials
used in INSTEAD-Registered Trademark- to improve the manufacturing process. An
applicable FDA regulation requires the filing of a new 510(k) notification when,
among other things, there is a major change or modification in the intended use
of the device, or a change or modification in material, chemical composition or
manufacturing process, that could significantly affect the device's safety or
effectiveness. A device manufacturer is responsible for making the initial
determination as to whether a proposed change to a cleared device or its
intended use necessitates the filing of a new 510(k) notification. The Company
has conducted testing subsequent to the changes, which the Company believes are
minor, in materials. The Company has been advised by its regulatory counsel,
Arent Fox Kintner Plotkin & Kahn, that no additional 510(k) notification is
required for these changes, although there can be no assurance that the FDA will
not require such a 510(k) notification. If a new 510(k) notification were to be
required by the FDA for the changes in materials of
INSTEAD-Registered Trademark-, there can be no assurance that the FDA would
clear a new 510(k) notification submitted by the Company, or that the FDA would
not prohibit the Company from selling INSTEAD-Registered Trademark- until the
510(k) notification was cleared. The FDA review time for 510(k) notifications
could be lengthy. The failure to obtain a new 510(k) clearance, if required, on
a timely basis, if at all, would have a material adverse effect on the Company's
business, financial condition and results of operations.
 
    The Company has also decided to label INSTEAD-Registered Trademark- with a
12 hour maximum wear time. The labeling for INSTEAD-Registered Trademark-, as
cleared by the FDA in the original 510(k) notification, included an 8 hour
maximum wear time. The Company conducted a clinical study to support the safety
of the 12 hour wear time. The
 
                                       6
<PAGE>
Company does not believe a new 510(k) notification is necessary to increase the
maximum wear time to 12 hours. Prior to finalizing the change in labeling, the
Company met with the FDA on June 19, 1996. At that meeting the results of these
studies were discussed and the FDA requested that the Company submit the results
of its clinical testing, which the Company provided on July 17, 1996. On October
25, 1996 the Company received a letter from the FDA confirming that the Company
could increase the wear time of INSTEAD-Registered Trademark- to 12 hours
without filing a new 510(k) notification.
 
    Any product with a 510(k) notification cleared by the FDA and its
manufacturer are subject to continuing regulatory review and the FDA has the
authority to, among other things, order or request restrictions on the
distribution of products or the withdrawal of products from market even after
clearance of a 510(k) submission is obtained.
 
    The Company's manufacturing facility in Missoula, Montana is subject to the
Good Manufacturing Practices ("GMP") regulations which are promulgated by the
FDA, international quality standards and other regulatory requirements. The
failure by the Company to comply with the foregoing could adversely affect the
Company's production and financial condition.
 
    In order to distribute INSTEAD-Registered Trademark- in foreign countries,
the Company must comply with all regulatory requirements of the countries in
which the Company intends to sell INSTEAD-Registered Trademark-, including
regulations with respect to labeling and importing into such countries and FDA
requirements for export thereto. There can be no assurance that the Company will
be able to comply with such requirements. The Company will require FDA clearance
or pre-market approval to market other applications of the SoftCup Technology in
the United States.
 
PRODUCT LIABILITY; POSSIBILITY OF INSUFFICIENT INSURANCE COVERAGE
 
    Testing, manufacturing and marketing of INSTEAD-Registered Trademark- entail
an inherent risk of product liability, and such risk may be increased because
INSTEAD-Registered Trademark- is used internally. The Company presently
maintains what it believes to be a sufficient level of product liability
insurance. Such insurance is expensive and, in the future, may not continue to
be available on acceptable terms, if at all. The Company's business, financial
condition and results of operations may be materially adversely affected by a
successful product liability claim, or series of such claims, in excess of any
insurance coverage. There can be no assurance that product liability claims will
not be successfully asserted against the Company.
 
COMPETITION
 
    The market for feminine protection and medical products is presently
dominated by large, long-established and well-financed companies which have
substantially greater resources than the Company. There can be no assurance that
other companies will not develop new or enhanced feminine protection products
that are either more effective than INSTEAD-Registered Trademark-, or would
render INSTEAD-Registered Trademark- obsolete or non-competitive. In addition,
there can be no assurance that existing competitive companies will not increase
their level of advertising and marketing expenditures in response to the
introduction of INSTEAD-Registered Trademark-. See "--Risks Associated with
Potential Competitive Response."
 
RISKS ASSOCIATED WITH POTENTIAL COMPETITIVE RESPONSE
 
    Subsequent to the Company's initial public offering of Common Stock (the
"IPO"), the Company identified its target geography for the initial launch of
INSTEAD-Registered Trademark-, established a broker network, and established
certain key trade accounts. The initial indications from the early stages of the
launch reflect higher costs related to trade, distribution and marketing
spending levels than previously anticipated. The Company believes that this is
due to the response to the launch of INSTEAD-Registered Trademark- by companies
with competitive products. There can be no assurance that the Company's
competitors will not significantly increase their spending on promotional
activities as a reaction to the introduction of INSTEAD-Registered Trademark-.
See
"--Marketing Risks; Uncertainty of Consumer Acceptance."
 
                                       7
<PAGE>
INHERENT LIMITATION OF MARKET RESEARCH AND CONSUMER USE TESTING
 
    The Company conducted test studies for the purposes of evaluating potential
consumer interest in INSTEAD-Registered Trademark- and developing a market
strategy for INSTEAD-Registered Trademark-. Due to the inherent limitations of
market research and consumer testing to accurately indicate consumer
preferences, the results of such research and tests may not accurately reflect
INSTEAD-Registered Trademark-'s actual market potential.
 
RISKS INHERENT IN OBTAINING AND PROTECTING PATENTS AND PROPRIETARY TECHNOLOGY
 
    The Company's success will depend, in part, on its ability to obtain and
protect patents and trade secrets, and operate without infringing the
proprietary rights of other companies and individuals in the United States and
abroad. A continuation patent application based on, and including the subject
matter of, a patent application for the SoftCup Technology (for use for feminine
protection during menstruation either with or without vaginal drug delivery)
originally filed by Ms. Audrey Contente, the founder of the Company, was allowed
by the United States Patent and Trademark Office (the "Patent and Trademark
Office") on December 11, 1992. The United States patent was issued on March 22,
1994 and expires on March 22, 2011. Additional patent applications are pending
in the United States on other aspects and applications of the SoftCup Technology
and certain manufacturing processes related to such technology. The Company has
also filed international patent applications with respect to the SoftCup
Technology (for use for feminine protection during menstruation either with or
without vaginal drug delivery). There can be no assurance that any additional
patents will issue or that any issued patents will provide the Company with
competitive advantages or will not be challenged by other companies or
individuals. There can be no assurance that other companies and individuals will
not independently develop similar products, duplicate the SoftCup Technology or
design around the Company's patent. In addition, the Company could incur
substantial costs in defending suits brought against it on such intellectual
property rights or in prosecuting suits that the Company brings against other
parties to protect its intellectual property rights. The Company also relies on
trade secrets and other unpatented proprietary technology. The Company seeks to
protect its trade secrets and proprietary know-how in part with confidentiality
agreements with employees and consultants. There can be no assurance that the
agreements will not be breached, that the Company will have adequate remedies
for any breach, or that the Company's trade secrets will not otherwise become
known or independently developed by competitors or that others will not
independently develop substantially equivalent proprietary products and
processes or otherwise gain access to the Company's proprietary technology.
 
RISKS ASSOCIATED WITH RESEARCH AND DEVELOPMENT FOR OTHER APPLICATIONS OF THE
  SOFTCUP TECHNOLOGY
 
    Although the Company is currently focusing its primary efforts and capital
resources on introducing INSTEAD-Registered Trademark- into the United States
and international markets, the Company intends to use a portion of its resources
to pursue research on potential medical and health care applications of the
SoftCup Technology. If such research leads to the development of new products,
the Company would require further additional capital and/or a strategic partner
to market and distribute such products. There can be no assurance that such
research or development will be successful, that these additional potential
applications of the SoftCup Technology will result in the Company's introduction
of other products or that any additional financing will be available or, if
available, will be on terms acceptable to the Company.
 
    The Company's focus on research and development of medical applications of
the SoftCup Technology is contingent on many factors which are generally
difficult to identify and quantify. They are dependent on a number of factors
which are not in the Company's control, including the results of clinical trials
and other scientific findings, and the regulatory requirements of clinical
testing and market approvals. See
"--Necessity of Regulatory Clearances to Market." Accordingly, there can be no
assurance that any of the goals or timetables described in, or incorporated by
reference into, this Prospectus relating to other potential applications of the
SoftCup Technology can be met.

DEPENDENCE ON KEY PERSONNEL
 
    The Company's success is dependent, in large part, on the continued service
of its key management, certain scientific and technical advisors and its ability
to attract and retain qualified employees. Competition for such employees is
intense. The Company has obtained key-person life insurance policies on the
lives of John W. Andersen, the President, Chief Executive Officer and Chairman
of the Board of the Company and on Audrey Contente, Executive Vice President and
Founder of the Company who invented the SoftCup Technology. There can be no
assurance that any such key-person life insurance will continue to be available
in the future to the Company at a satisfactory premium.
 
CERTAIN ANTI-TAKEOVER PROVISIONS
 
    Certain provisions of the Company's Restated Certificate of Incorporation
and Amended and Restated By-Laws could have the effect of discouraging a third
party from pursuing a non-negotiated takeover of the Company and preventing
certain changes in control. The Restated Certificate of Incorporation provides
that the Board of Directors is divided into three classes. One class of
directors is elected at each annual meeting of stockholders for a three-year
term. The Restated Certificate of Incorporation restricts certain business
combinations with an interested stockholder (typically a beneficial owner of 15%
or more of the outstanding voting shares of the Company's capital stock,
excluding certain persons). In addition, the Amended and Restated By-Laws and
the Restated Certificate of Incorporation require advance notice to the Board of
Directors of stockholder proposals or stockholder nominees for directors to be
considered at the next annual meeting of stockholders and restrict the ability
of stockholders to call meetings. The Restated Certificate of Incorporation and
Amended and Restated By-Laws also limit the ability of stockholders to remove
directors, call stockholders meetings and act by written consent and provide
that vacancies in the Board of Directors may only be filled by a majority of the
remaining directors. In addition, the Company's Restated Certificate of
Incorporation authorizes the issuance of 5,000,000 shares of preferred stock
with such designation, rights and preferences as may be determined from time to
time by the Board of Directors. The Board of Directors may, without stockholder
approval, issue preferred stock with dividend, liquidation, conversion, voting
or other rights which could adversely affect the voting power or other rights of
the holders of the Common Stock. There can be no assurance that the Company will
not issue additional shares of preferred stock in the future. These provisions
could discourage a third party from pursuing a takeover of the Company at a
price considered attractive by many stockholders, since such provisions could
have the effect of delaying an acquiring party from gaining control of the
Company and its Board of Directors. See "Description of Capital Stock--Preferred
Stock" and
"--Certain Provisions of the Company's Certificate of Incorporation and
By-Laws."
 
LIMITED TRADING HISTORY; VOLATILITY OF PRICE
 
    Prior to the IPO, there had been no public trading market for the Common
Stock, and there can be no assurance that a regular trading market for the
Common Stock will continue after the Offering or that the market price for the
Common Stock will not fall. In addition, market prices of securities of many
companies in the earlier stages of development have experienced wide
fluctuations not necessarily related to the operating performance of such
companies. For example, the price of the Common Stock ranged from $14 3/8 on May
1, 1996 to $36 on May 22, 1996, closing at $19 3/8 on June 28, 1996. On October
31, 1996 the staff of the Commission informed the Company that it had commenced
an informal inquiry with respect to certain matters, which the Company believes
relates to the volatility of the price of its Common Stock in the May and June
1996 period. The Company believes it has complied with all securities laws and,
although the Commission has not requested any information from the Company, the
Company has informed the Commission that it wishes to assist the Commission with
its inquiry. While there can be no assurance as to the scope or outcome of any
inquiry by the Commission, the Company believes that this matter will not have a
material adverse effect on its business, prospects, financial condition or
results of operations. The Company further believes that factors such as
legislative, regulatory and technological
 
                                       9
<PAGE>
developments and quarterly variations in financial results and market conditions
could cause the market price of the Common Stock to fluctuate substantially.
These market fluctuations may adversely affect the price of and market for the
Common Stock and could result in additional inquiries. See "Price Range of
Common Stock."
 
SUBSTANTIAL AMOUNT OF SHARES ELIGIBLE FOR FUTURE SALE; POTENTIAL ADVERSE EFFECT
  ON MARKET PRICE OF COMMON STOCK
 
    Upon consummation of the Offering, the Company will have 11,671,592 shares
of Common Stock outstanding. In addition, as of March 31, 1997, there has been
reserved 1,327,031 shares of Common Stock for issuance upon the conversion or
exercise of outstanding securities. The 5,910,000 shares of Common Stock sold in
the Company's underwritten public offerings, other than shares which may have
been purchased by "affiliates" of the Company, will be freely tradeable without
restriction or further registration under the Securities Act. On December 12,
1996, the Company filed a Registration Statement on Form S-8 (Reg. No.
333-17765) with respect to 1,708,612 shares of Common Stock issuable pursuant to
its stock option plans and certain options and warrants which have been granted
to employees and consultants of the Company; such Registration Statement
includes 1,312,031 shares of Common Stock issued or issuable upon conversion or
exercise of outstanding securities of the Company. Approximately 1,463,016 of
the remaining shares of Common Stock outstanding and issuable upon conversion or
exercise of outstanding securities would be "restricted securities," as that
term is defined under Rule 144 promulgated under the Securities Act ("Rule
144"), and may only be sold pursuant to a registration statement under the
Securities Act or an applicable exemption from the registration requirements of
the Securities Act, including Rule 144.
 
    All officers, directors and certain security holders agreed with Hampshire
in connection with the IPO not to, directly or indirectly, offer, sell, contract
to sell or otherwise dispose of their shares of Common Stock, or other
securities convertible into or exercisable for shares of Common Stock, without
the prior written consent of Hampshire, prior to August 22, 1997. An aggregate
of 4,896,530 shares of Common Stock outstanding and issuable upon conversion or
exercise of outstanding securities are subject to these lock-up arrangements.
Hampshire has agreed with Jefferies & Company, Inc. ("Jefferies"), an
underwriter for the Company's second public offering of Common Stock, not to
release any of such security holders from the contractual restriction without
the prior written consent of Jefferies. The Company has, subject to certain
exceptions, agreed not to offer, issue or sell any shares of Common Stock or
securities exercisable for or convertible into shares of Common Stock until May
13, 1997 without the prior written consent of Jefferies, and until August 22,
1997 without the prior written consent of Hampshire. No predictions can be made
as to the effect, if any, that market sales of shares of existing stockholders
or the availability of such shares for future sale will have on the market price
of shares of Common Stock prevailing from time to time. The prevailing market
price of the Common Stock after the Offering could be adversely affected by
future sales of substantial amounts of Common Stock by existing stockholders.
 
LACK OF DIVIDENDS
 
    The Company has generated limited revenues to date and does not expect to
pay cash dividends for the foreseeable future.

Selling Stockholders.
 
                          PRICE RANGE OF COMMON STOCK
 
    The Common Stock was initially offered to the public on February 22, 1996 at
a price of $10.00 per share and is quoted on the Nasdaq National Market. The
following table sets forth the range of high and low sale prices for the Common
Stock for the periods indicated as reported on the Nasdaq National Market.

    On May 15, 1997, the last sale price of the Common Stock was $14 5/8 as
reported on the Nasdaq National Market. At March 31, 1997, there were 221
stockholders of record of the Common Stock.
 
                                DIVIDEND POLICY
 
    The Company has not paid any dividends on its Common Stock to date. The
payment of dividends, if any, in the future is within the discretion of the
Board of Directors and will depend on the Company's earnings, its capital
requirements and financial condition. It is the present intention of the Board
of Directors to retain all earnings, if any, for use in the Company's business
operations and, accordingly, the Board of Directors does not expect to declare
or pay any cash dividends in the foreseeable future.

Directors out of funds legally available therefor. In the event of a liquidation
or dissolution of the Company, holders of Common Stock are entitled to share
ratably in all assets remaining after payment of liabilities and the liquidation
preference of any outstanding preferred stock. Holders of shares of Common
Stock, as such, have no conversion, preemptive or other subscription rights, and
there are no redemption provisions applicable to the Common Stock. All of the
outstanding shares of Common Stock are, and the shares of Common Stock offered
hereby, when issued against the consideration set forth in this Prospectus, will
be, fully paid and nonassessable.
 
PREFERRED STOCK
 
    The Company is authorized to issue 5,000,000 shares of the Preferred Stock,
none of which shares are outstanding as of the date of this Prospectus. The
Board of Directors of the Company has the authority at any time and from time to
time to establish and designate one or more series of preferred stock, to fix
the number of shares of any series (which number may vary between series) and to
fix the dividend rights and preferences, the redemption price (if any) and
terms, liquidation rights, sinking fund provisions (if any), conversion
provisions (if any) and the voting powers (if any). The Board of Directors,
without stockholder approval, could issue preferred stock with voting and
conversion rights that could adversely affect the voting power of holders of the
Common Stock. Certain companies have used the issuance of preferred stock as an
anti-takeover device, and the Board of Directors of the Company could, without
stockholder approval, issue preferred stock with certain voting, conversion
and/or redemption rights that could discourage any attempt to obtain control of
the Company in a transaction not approved by the Board of Directors. The Board
of Directors has authorized the issuance of 48,750 shares of Series A Preferred
Stock and previously issued 6,532.5 shares of Series A Preferred Stock. As of
the date of this Prospectus all issued and outstanding shares of Series A
Preferred Stock had been converted into Common Stock. The rights, preferences,
privileges, restrictions and other matters relating to such shares are as
follows:
 
    DIVIDENDS.  Each share of Series A Preferred Stock is entitled to receive
cumulative dividends at an annual rate of $8.00 per share. Upon conversion into
Common Stock, all cumulative dividends in arrears will be forfeited. Holders of
Series A Preferred Stock are entitled to receive such cumulative annual
dividends prior to the payment of any dividend in respect of the Common Stock
(the "Series A Preferred Stock Dividend Preference"). If the Series A Preferred
Stock Dividend Preference is not either fully paid or declared, then no
distribution shall be made on any Common Stock (although the arrearage shall
accumulate) and the Company will not redeem or purchase any Common Stock or make
monies available for a sinking fund for the redemption or purchase of any Common
Stock. Holders of Series A Preferred Stock are entitled to share in any dividend
after payment of the Series A Preferred Stock Dividend Preference in the
proportion that the number of Series A Preferred Stock outstanding bears to the
total number of all shares outstanding (whether preferred stock or Common
Stock), treating such holders as if they had converted such Series A Preferred
Stock into Common Stock.
 
                                       17
<PAGE>
    LIQUIDATION PREFERENCE.  Upon reducing the Company's capital (which results
in a distribution of assets) or upon any voluntary or involuntary liquidation,
dissolution or winding-up of the Company (collectively, a "Liquidating Event"),
the holders of the Series A Preferred Stock shall be entitled to receive, before
any distribution of assets to the holders of the Common Stock, a liquidation
preference (the "Series A Preferred Stock Liquidation Preference"). For each
outstanding share of Series A Preferred Stock, the Series A Preferred Stock
Liquidation Preference shall be equal to the sum of (i) One Hundred Dollars
($100.00) and (ii) any unpaid Series A Preferred Stock Dividend Preference. The
Series A Preferred Stock Dividend Preference shall be paid after the Series A
Preferred Stock Liquidation Preference, and the Series A Preferred Stock
Liquidation Preference shall be distributed ratably among the holders of the
Series A Preferred Stock in proportion to the number of shares owned by each
holder of such stock. After payment of the Series A Preferred Stock Liquidation
Preference, the Company's assets available for distribution shall be distributed
among the holders of Series A Preferred Stock and Common Stock PRO RATA, based
on the number of shares of stock held by each, treating such holders of Series A
Preferred Stock as if they had converted such stock into Common Stock
immediately before such distribution. If, upon any Liquidating Event, the
amounts payable with respect to the Series A Preferred Stock and any other stock
of the Company ranking as to any such distribution on a parity with the Series A
Preferred Stock are not paid in full, the holders of the Series A Preferred
Stock and such parity stock shall share ratably in any such distribution of
assets of the Company in proportion to the full preferential amounts to which
they are entitled.
 
    VOTING.  In general, the holder of each share of the Series A Preferred
Stock shall (i) be entitled to the number of votes equal to the number of shares
of Common Stock into which such share of Series A Preferred Stock could be
converted on the record date for the vote or the date of the solicitation of any
written consent of stockholders, (ii) have voting rights and powers equal to the
voting rights and powers of the Common Stock and (iii) be entitled to notice of
any stockholders' meeting in accordance with the By-Laws of the Company.
Fractional votes shall not, however, be permitted.
 
    RIGHT TO CONVERT.  Each share of Series A Preferred Stock shall be
convertible, at any time at the option of the holder, into shares of Common
Stock at a conversion rate equal to the quotient obtained by dividing One
Hundred Dollars ($100.00) by a conversion price, initially equal to $8.00 per
share (the "Conversion Price"). The Conversion Price shall be adjusted from time
to time to protect against dilution. No fractional share shall be issued upon
the conversion of any share or shares of Series A Preferred Stock. See "--
Anti-Dilution" below.
 
    ANTI-DILUTION.  If the Company issues any shares of Common Stock or
convertible preferred stock, or rights to purchase Common Stock, warrants,
options, other rights or other securities (to the extent such other rights or
securities are convertible into or exchangeable or exercisable for shares of
Common Stock) for consideration per share less than the prevailing Conversion
Price, then the Conversion Price in effect immediately before such issuance
shall be adjusted to a price equal to the consideration per share received by
the Company. If the number of shares of Common Stock outstanding is increased by
a Common Stock dividend or by subdivision or split-up of Common Stock, then the
Conversion Price shall be appropriately decreased in proportion to such increase
in outstanding shares. If the number of shares of Common Stock outstanding is
decreased by a combination of the outstanding shares of Common Stock, then the
Conversion Price shall be appropriately increased in proportion to such decrease
in outstanding shares.
 
    If there is any reorganization, reclassification, consolidation or merger
(including a merger in which the Company is the surviving entity) of the
Company, then each share of Series A Preferred Stock shall (in lieu of being
exercisable for shares of Common Stock), after such reorganization,
reclassification, consolidation or merger, be exercisable into the kind and
number of shares of stock or other securities or property (including cash) of
the Company or of the corporation resulting from such consolidation or surviving
such merger to which the holder of the number of shares of Common Stock
deliverable (immediately before the time of such reorganization,
reclassification, consolidation or merger) upon conversion of such Series A
 
                                       18
<PAGE>
Preferred Stock would have been entitled upon such reorganization,
reclassification, consolidation or merger.
 
    AUTOMATIC CONVERSION.  Each share of Series A Preferred Stock shall
automatically convert into shares of Common Stock immediately upon (i) the
closing of the sale of the Common Stock in a firm commitment, underwritten
public offering registered under the Securities Act (other than a registration
relating solely to a transaction under Rule 145 thereunder or to an employee
benefit plan), at a public offering price equal to or exceeding $20.00 per share
of Common Stock (appropriately adjusted for any recapitalization) and the
aggregate net proceeds to the Company (before deduction for underwriters'
commissions and expenses relating to the issuance, including without limitation
fees of the Company's counsel) of which equal or exceed $15.0 million or (ii)
receipt by the Company of the affirmative vote, at a duly noticed stockholders'
meeting or pursuant to a duly solicited written consent of approval of the
holders of at least a majority of the outstanding shares of the Series A
Preferred Stock voting together as a single class, in favor of converting all of
the Series A Preferred Stock into Common Stock.
 
SECTION 203 OF THE DELAWARE GENERAL CORPORATION LAW
 
    The Company is subject to the provisions of Section 203 of the Delaware
General Corporation Law ("DGCL"). Section 203 provides, with certain exceptions,
that a Delaware corporation may not engage in certain business combinations with
a person or affiliate or associate of such person who is an "interested
stockholder" for a period of three years from the date such person became an
interested stockholder unless: (i) the transaction resulting in the acquiring
person's becoming an interested stockholder, or the business combination, is
approved by the Board of Directors of the Company before the person becomes an
interested stockholder; (ii) the interested stockholder acquires 85% or more of
the outstanding voting stock of the Company in the same transaction which makes
it an interested stockholder (excluding certain employee stock option plans); or
(iii) on or after the date the person becomes an interested stockholder, the
business combination is approved by the Company's board of directors and by the
holders of at least 66 2/3% of the Company's outstanding voting stock at an
annual or special meeting, excluding shares owned by the interested stockholder.
An "interested stockholder" is defined as any person that is (x) the owner of
15% or more of the outstanding voting stock of the Company or (y) an affiliate
or associate of the Company and was the owner of 15% or more of the outstanding
voting stock of the Company at any time within the three year period immediately
prior to the date on which it is sought to be determined whether such person is
an interested stockholder.
 
DIRECTORS' LIABILITY
 
    The Company's Restated Certificate of Incorporation contains provisions to
(i) eliminate the personal liability of its directors for monetary damages
resulting from breaches of their fiduciary duty (other than breaches of the duty
of loyalty, acts or omissions not in good faith or which involve intentional
misconduct or a knowing violation of law, violations under Section 174 of the
DGCL, for any transaction from which the director derived an improper personal
benefit or any act or omission occurring prior to the date when the provision
became effective) and (ii) indemnify its directors and officers to the fullest
extent permitted by Section 145 of the DGCL, including circumstances in which
indemnification is otherwise discretionary. The Company believes that these
provisions are necessary to attract and retain qualified persons as directors
and officers.
 
CERTAIN PROVISIONS OF THE COMPANY'S CERTIFICATE OF INCORPORATION AND BY-LAWS
 
    The Company's Restated Certificate of Incorporation and Amended and Restated
By-Laws contain several provisions that may be deemed to have the effect of
making more difficult the acquisition of control of the Company by means of a
hostile tender offer, open market purchases, a proxy contest or otherwise. The
provisions of the Restated Certificate of Incorporation and the Amended and
Restated By-Laws discussed below are designed to help to ensure that holders of
Common Stock are treated fairly and
 
                                       19
<PAGE>
equally in a multistep acquisition. In addition, they are intended to encourage
persons seeking to acquire control of the Company to initiate such an
acquisition through arm's-length negotiations with the Company's Board of
Directors.
 
    CLASSIFIED BOARD OF DIRECTORS.  The Company's Restated Certificate of
Incorporation provides that the Board of Directors shall be divided into three
classes of directors serving staggered terms. One class of directors will be
elected at each annual meeting of stockholders for a three-year term. Thus, at
least two annual meetings of stockholders, instead of one, generally will be
required to change the majority of the Company's Board of Directors. This may
have the effect of making it more difficult to acquire control of the Company by
means of a hostile tender offer, open market purchases, a proxy contest or
otherwise.
 
    STOCKHOLDER MEETINGS.  Subject only to the rights of holders of preferred
stock, only a majority of the Company's Board of Directors, the Chairman, the
President or Chief Executive Officer will be able to call an annual meeting of
stockholders and only a majority of the Company's Board of Directors, by
majority vote, or the Chairman, the President or the Chief Executive Officer,
will be able to call a special meeting of stockholders. In addition, subject
only to the rights of holders of preferred stock, stockholders may not take any
action by written consent.
 
    RESTRICTIONS ON CERTAIN BUSINESS COMBINATIONS.  The Company's Restated
Certificate of Incorporation provides that certain business combinations such as
mergers and stock and assets sales, with an interested stockholder (typically a
beneficial owner of more than 15% of the outstanding voting shares of the
Company's capital stock, excluding certain persons), be approved by (a) the
holders of 75% of the voting power of the then outstanding voting shares, voting
together as a single class, and (b) at least a majority of the voting power of
the then outstanding voting shares, voting as a single class, which are not
owned beneficially, directly or indirectly, by the interested stockholder,
unless the transaction is approved by a majority of certain directors or meets
certain fair price provisions.
 
    REQUIREMENTS FOR ADVANCE NOTIFICATION OF STOCKHOLDER NOMINATIONS AND
PROPOSALS.  The Company's Restated Certificate of Incorporation establishes
advance notice procedures with regard to stockholder nominations, other than by
or at the direction of the Board of Directors, of candidates for election as
directors. The Amended and Restated By-Laws establishes advance notice
procedures with regard to stockholder proposals other than by or at the
direction of the Board of Directors of business to be brought before a meeting.
 
    VOTE REQUIRED TO AMEND OR REPEAL CERTAIN PROVISIONS OF THE COMPANY'S
RESTATED CERTIFICATE OF INCORPORATION AND AMENDED AND RESTATED BY-LAWS.  The
Company's Restated Certificate of Incorporation establishes certain super
majority voting requirements to amend or repeal certain provisions of the
Company's Restated Certificate of Incorporation and Amended and Restated
By-Laws.
 
TRANSFER AGENT AND REGISTRAR
 
    The transfer agent and registrar for the Common Stock is American Stock
Transfer & Trust Company, New York, New York.
 
                                       20
<PAGE>
                              PLAN OF DISTRIBUTION
 
    Any or all of the Shares may be sold from time to time to purchasers
directly by the Selling Stockholders. Alternatively, the Selling Stockholders
may from time to time offer the Shares through underwriters, dealers or agents
who may receive compensation in the form of underwriting discounts, concessions
or commissions from the Selling Stockholders and/or the purchasers of the Shares
for whom they may act as agents. The Selling Stockholders and any such
underwriters, dealers or agents that participate in the distribution of the
Shares may be deemed to be underwriters under the Securities Act, and any profit
on the sale of the Shares by them and any discounts, commissions or concessions
received by them may be deemed to be underwriting discounts and commissions
under the Securities Act. The Shares may be sold from time to time in one or
more transactions at a fixed offering price, which may be changed, or at varying
prices determined at the time of sale or at negotiated prices. The distribution
of the Shares by the Selling Stockholders may be effected in one or more
transactions that may take place on Nasdaq National Market, including ordinary
brokers' transactions, privately-negotiated transactions or through sales to one
or more broker-dealers for resale of such shares as principals, at market prices
prevailing at the time of sale, at prices related to such prevailing market
prices or at negotiated prices. Usual and customary or specifically negotiated
brokerage fees, discounts and commissions may be paid by the Selling
Stockholders in connection with such sales of securities.
 
    At the time a particular offer of the Shares is made, to the extent
required, a supplement to this Prospectus will be distributed (or, if required,
a post-effective amendment to the Registration Statement of which this
Prospectus is a part will be filed) which will identify the specific Shares
being offered and set forth the aggregate amount of Shares being offered, the
purchase price and the terms of the offering, including the name or names of the
Selling Stockholders and of any underwriters, dealers or agents, the purchase
price paid by any underwriter for Shares purchased from the Selling Stockholder,
any discounts, commissions and other items constituting compensation from the
Selling Stockholders and/or the Company and any discounts, commissions or
concessions allowed or reallowed or paid to dealers, including the proposed
selling price to the public. In addition, an underwritten offering will require
clearance by the National Association of Securities Dealers, Inc. of the
underwriter's compensation arrangements. The Company will not receive any of the
proceeds from the sale by the Selling Stockholders of the Shares offered hereby.
All of the filing fees and other expenses of this Registration Statement will be
borne in full by the Company, other than any underwriting fees, discounts and
commissions relating to this Offering.
 
    Pursuant to certain agreements granting registration rights to certain
Selling Stockholders, which were executed in connection with a 1995 private
placement, the Company will use its best efforts to keep the Registration
Statement, of which this Prospectus forms a part, effective under the Securities
Act for a period of five and one half years after February 22, 1996 and the
Company will pay substantially all of the expenses incident to the Offering and
sale of the Shares to the public, other than underwriting fees, discounts and
commissions. Most of the agreements which provide for registration rights to the
Selling Stockholders provide for cross-indemnification of the Selling
Stockholders and the Company, to the extent permitted by law, for losses,
claims, damages, liabilities and expenses arising, under certain circumstances,
out of any registration of the Shares. The registration rights agreements also
provide that in connection with an underwritten offering, the Company will
indemnify the underwriters thereof, their officers and directors and each person
who controls such underwriters (within the meaning of the Securities Act) to the
same extent as provided with respect to the indemnification of the Selling
Stockholders signatory to such agreement, except with respect to information
provided by such underwriters specifically for inclusion within the appropriate
registration statement.
 
    In order to comply with certain states securities laws, if applicable, the
Shares will be sold in such jurisdictions only through registered or licensed
brokers or dealers. In certain states the Shares may not be sold unless the
Shares have been registered or qualified for sale in such state, or unless an
exemption from registration or qualification is available and is obtained.
 
                                       21
<PAGE>
    In addition, certain holders of Common Stock, as well as the officers and
directors of the Company, are subject to a contractual restriction prohibiting
the offer and/or sale of their shares of Common Stock or other securities of the
Company, prior to August 22, 1997, without the prior written consent of
Hampshire. Hampshire has agreed with Jefferies not to release any of such
stockholders from the contractual restriction without the prior written consent
of Jefferies.
 
    In addition to sales pursuant to the Registration Statement of which this
Prospectus forms a part, the Shares may be sold in accordance with Rule 144.
 
                                 LEGAL MATTERS
 
    Certain legal matters will be passed upon for the Company by Shereff,
Friedman, Hoffman & Goodman, LLP, New York, New York. Martin Nussbaum, a member
of Shereff, Friedman, Hoffman & Goodman, LLP, is a director of the Company and a
Selling Stockholder; certain other members of the firm are also Selling
Stockholders. See "Selling Stockholders."
