Dear Stockholders:
 
  You are cordially invited to attend a Special Meeting of Stockholders of
FluoroScan Imaging Systems, Inc. ("FluoroScan"), which will be held at the
offices of Katten Muchin & Zavis, 525 West Monroe Street, Chicago, Illinois
60661, on Thursday, August 29, 1996, at 8:00 a.m., local time.
 
  At this important meeting you will be asked to consider and vote upon a
proposal to approve and adopt an Agreement and Plan of Merger, dated as of
July 18, 1996 (the "Merger Agreement"), by and among FluoroScan, Hologic, Inc.
("Hologic"), and Fenway Acquisition Corp., a newly-formed and wholly-owned
subsidiary of Hologic ("Merger Sub"), and the merger (the "Merger") of Merger
Sub with and into FluoroScan. If the Merger Agreement and the Merger are
approved, and the Merger becomes effective, FluoroScan will become a wholly-
owned subsidiary of Hologic and each outstanding share of FluoroScan Common
Stock issued and outstanding immediately prior to the consummation of the
Merger (the "Effective Time") will be converted into the right to receive
 .31069 shares of Hologic Common Stock, subject to adjustment as described
below (the "Conversion Ratio"). If the average closing price per share of the
Hologic Common Stock as quoted on the Nasdaq National Market for the ten
trading days ending two business days prior to the Effective Time (the
"Average Market Value") is greater than $50.29, the Conversion Ratio will be
adjusted to equal $15.63 divided by the Average Market Value. If the Average
Market Value is less than $30.17, at Hologic's election the Conversion Ratio
will be adjusted to equal $9.37 divided by the Average Market Value. If the
Average Market Value is less than $30.17, and Hologic does not elect to adjust
the Conversion Ratio, the Board of Directors of FluoroScan may elect to
terminate the Merger Agreement and the Merger. Under Delaware Law, FluoroScan
stockholders will not be entitled to any appraisal rights with respect to the
Merger.
 
  Rodman & Renshaw, Inc. ("Rodman") was retained by FluoroScan to act as its
independent financial advisor in connection with the Merger. As discussed in
the accompanying Proxy Statement/Prospectus, Rodman has delivered to the
FluoroScan Board of Directors its written opinion, dated July 18, 1996, that,
as of the date of such opinion and subject to certain assumptions, factors and
limitations set forth in such opinion, the Conversion Ratio to be offered to
FluoroScan's stockholders pursuant to the Merger is fair, from a financial
point of view, to such stockholders. A copy of the opinion of Rodman is
attached as Appendix B to the accompanying Proxy Statement/Prospectus, and you
are urged to read it in its entirety.
 
  YOUR BOARD OF DIRECTORS HAS DETERMINED THAT THE MERGER IS FAIR AND IN THE
BEST INTERESTS OF FLUOROSCAN AND ITS STOCKHOLDERS, HAS UNANIMOUSLY APPROVED
THE MERGER AGREEMENT AND UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS VOTE FOR
THE APPROVAL AND ADOPTION OF THE MERGER AGREEMENT AND THE MERGER.
 
  YOU SHOULD NOT RETURN CERTIFICATES FOR FLUOROSCAN COMMON STOCK WITH THE
ENCLOSED PROXY CARD. YOU SHOULD NOT FORWARD YOUR STOCK CERTIFICATES UNTIL YOU
HAVE RECEIVED A TRANSMITTAL LETTER FROM THE EXCHANGE AGENT.
 
  It is important that your shares be represented at the Special Meeting,
regardless of the number you hold. Therefore, please sign, date and return the
enclosed proxy card as soon as possible, whether or not you plan to attend the
Special Meeting. This will not prevent you from voting your shares in person
if you subsequently choose to attend the Special Meeting.
 
                                          Sincerely,
 
 
                                          Larry S. Grossman

                               ----------------
  A Special Meeting of Stockholders of FluoroScan Imaging Systems, Inc., a

are described more fully in the accompanying Proxy Statement/Prospectus:
 
    (1) To consider and vote upon a proposal to approve and adopt an
  Agreement and Plan of Merger, dated as of July 18, 1996 (the "Merger
  Agreement"), by and among FluoroScan, Hologic, Inc., a Delaware corporation
  ("Hologic"), and Fenway Acquisition Corp., a Delaware corporation and
  wholly-owned subsidiary of Hologic ("Merger Sub"), and the merger (the

  subsidiary of Hologic and each share of FluoroScan Common Stock, par value
  $0.0001 per share (the "FluoroScan Common Stock"), issued and outstanding
  immediately prior to the Effective Time will be converted into the right to
  receive .31069 shares of Hologic Common Stock, $.01 par value per share
  (the "Hologic Common Stock"), subject to adjustment as described below (the
  "Conversion Ratio"). If the average closing price per share of the Hologic
  Common Stock as quoted on the Nasdaq National Market for the ten trading
  days ending two business days prior to the Effective Time (the "Average
  Market Value") is greater than $50.29, the Conversion Ratio will be
  adjusted to equal $15.63 divided by the Average Market Value, and (ii) if
  the Average Market Value is less than $30.17, at Hologic's election the
  Conversion Ratio will be adjusted to equal $9.37 divided by the Average
  Market Value. If the Average Market Value is less than $30.17, and Hologic
  does not elect to adjust the Conversion Ratio, the Board of Directors of
  FluoroScan may elect to terminate the Merger Agreement and the Merger.
 
    (2) To transact such other business as may properly come before the

date will be entitled to notice of, and to vote at, the Special Meeting or any
adjournments or postponements thereof.

 [HOLOGIC LOGO] [FLUOROSCAN LOGO]HOLOGIC, INC.
 
                                  PROSPECTUS
 
                         COMMON STOCK, $0.01 PAR VALUE
 
                               ---------------
 
  This Proxy Statement/Prospectus is being furnished to stockholders of
FluoroScan Imaging Systems, Inc., a Delaware corporation ("FluoroScan"), in
connection with the solicitation of proxies by the Board of Directors of
FluoroScan for use at a Special Meeting of Stockholders to be held at the
offices of Katten Muchin & Zavis, 525 West Monroe Street, Chicago, Illinois
60661, on Thursday, August 29, 1996, at 8:00 a.m., local time, and at any and
all adjournments or postponements thereof (the "Special Meeting").
 
  This Proxy Statement/Prospectus relates to the proposed merger (the
"Merger") of Fenway Acquisition Corp. ("Merger Sub"), a Delaware corporation
and wholly-owned subsidiary of Hologic, Inc., a Delaware corporation
("Hologic"), with and into FluoroScan, with FluoroScan surviving the Merger,
pursuant to an Agreement and Plan of Merger, dated as of July 18, 1996, a copy
of which is attached hereto as Appendix A (the "Merger Agreement"), among
FluoroScan, Merger Sub and Hologic. As a result of the Merger, FluoroScan will
become a wholly-owned subsidiary of Hologic.
 
  At the effective time of the Merger (the "Effective Time"), each outstanding
share of FluoroScan Common Stock, $0.0001 par value per share ("FluoroScan
Common Stock"), issued and outstanding immediately prior to the Effective Time
will be converted into the right to receive .31069 shares of Hologic Common
Stock, $.01 par value per share (the "Hologic Common Stock"), subject to
adjustment as described below (the "Conversion Ratio"). If the average closing
price of the Hologic Common Stock as quoted on the Nasdaq National Market for
the ten trading days ending two business days prior to the Effective Time (the
"Average Market Value") is greater than $50.29, the Conversion Ratio will be
adjusted to equal $15.63 divided by the Average Market Value, and (ii) if the
Average Market Value is less than $30.17, at Hologic's election the Conversion
Ratio will be adjusted to equal $9.37 divided by the Average Market Value. If
the Average Market Value is less than $30.17, and Hologic does not elect to
adjust the Conversion Ratio, the Board of Directors of FluoroScan may elect to
terminate the Merger Agreement and the Merger. Holders of FluoroScan Common
Stock shall also have the right to receive together with each share of Hologic
Common Stock issued in connection with the Merger, an associated common stock
purchase right ("Hologic Purchase Right") pursuant to the Rights Agreement
dated as of December 22, 1992, as amended (the "Rights Agreement"), between
Hologic and American Stock Transfer & Trust Company, as Rights Agent.
References herein to the Hologic Common Stock issuable in the Merger shall be
deemed to include the associated Hologic Purchase Rights. As of the Record
Date, there were 4,622,894 shares of FluoroScan Common Stock outstanding.
Assuming no adjustment to the Conversion Ratio, and without giving effect to
the issuance of any shares of FluoroScan Common Stock after the Record Date,
upon consummation of the Merger, Hologic will issue approximately 1,436,287
shares of Hologic Common Stock.
 
  This Proxy Statement/Prospectus also constitutes the Prospectus of Hologic
under the Securities Act of 1933, as amended (the "Securities Act"), with
respect to the shares of Hologic Common Stock to be issued in connection with
the Merger. Shares of Hologic Common Stock are traded on the Nasdaq National
Market under the symbol "HOLX." On August 5, 1996, the closing sales price of
the Hologic Common Stock, as reported on the Nasdaq National Market, was
$37.25 per share.
 
  This Proxy Statement/Prospectus, the accompanying Notice of Special Meeting
and the accompanying form of proxy are first being mailed to FluoroScan
stockholders on or about August 7, 1996.
 
  The Board of Directors of FluoroScan has unanimously determined that the
Merger is fair to and in the best interests of FluoroScan and its
Stockholders, unanimously approved the Merger Agreement (and the transactions
contemplated thereby) and unanimously recommends that holders of FluoroScan
Common Stock vote FOR the approval and adoption of the Merger Agreement and
the Merger. See "The Merger and Related Transactions--Background of the
Merger," "--FluoroScan's Reasons for the Merger," "--Recommendation of
FluoroScan Board of Directors," and "--Interests of Certain Persons in the

  The following is a brief summary of certain information contained elsewhere
in this Proxy Statement/Prospectus, including the Appendices hereto. This
summary does not contain a complete statement of all material information
relating to the Merger Agreement and the Merger and is subject to, and
qualified in its entirety by, the more detailed information and financial
statements contained elsewhere in this Proxy Statement/Prospectus. FluoroScan
stockholders are urged to carefully read this Proxy Statement/Prospectus and
the attached Appendices in their entirety. Forward-looking statements made in
this Proxy Statement/Prospectus are made pursuant to the safe harbor provisions
of the Private Securities Litigation Reform Act of 1995. All forward-looking
statements involve risks and uncertainties, and actual results could differ
materially from those set forth in the forward-looking statements contained
herein, including as a result of the risks described below under "Risk
Factors."
 
                                 THE COMPANIES
 
HOLOGIC
 
  Hologic, Inc., a Delaware corporation ("Hologic"), is a leading international
developer, manufacturer and marketer of X-ray bone densitometers which
precisely measure bone density for use in the diagnosis and monitoring of
metabolic bone diseases such as osteoporosis. Hologic pioneered the use of
dual-energy X-ray absorptiometry ("DXA") to measure bone density, introducing
the first DXA bone densitometer in 1987. Since this introduction, DXA systems
have become the standard for measuring bone density. In 1995, Hologic
introduced its fourth generation of DXA bone densitometers, its clinically
oriented QDR(R) 4500 ACCLAIM(TM) product line. Hologic is also developing
products that it believes will complement its DXA product line, including an
ultrasound bone analyzer, the Sahara(TM) and, through a joint development
effort with another company, a diagnostic strip test to detect biochemical
markers that indicate the rate of a patient's bone loss. The mailing address of
Hologic's principal executive offices is: 590 Lincoln Street, Waltham,
Massachusetts 02154, and its telephone number is: (617) 890-2300.
 
FENWAY ACQUISITION CORP.
 
  Fenway Acquisition Corp., a wholly-owned subsidiary of Hologic ("Merger
Sub"), is a newly formed Delaware corporation created for the sole purpose of
consummating the transactions contemplated by the Merger Agreement. Merger Sub
has not conducted any activities other than those incident to its formation,
its execution of the Merger Agreement and its participation in the preparation
of this Proxy Statement/Prospectus. As a result of the Merger, Merger Sub will
be merged with and into FluoroScan, with FluoroScan surviving the Merger and
becoming a wholly-owned subsidiary of Hologic. The mailing address and
telephone number of Merger Sub are the same as those of Hologic.
 
FLUOROSCAN
 
  FluoroScan Imaging Systems, Inc., a Delaware corporation ("FluoroScan"),
manufactures and distributes the FluoroScan Imaging System(TM) (the "FluoroScan
System"), a low intensity, real time X-ray imaging device which provides high
resolution images at radiation levels and at a cost well below those of
conventional X-ray and fluoroscopic equipment. The FluoroScan System technology
is based on a micro channel plate image intensifier commonly known as a "night
vision" intensifier. To date, FluoroScan has sold the FluoroScan System
primarily to hospitals and surgery centers for use by orthopedic surgeons in
the operating room and, to a lesser extent, for other medical uses. FluoroScan
was incorporated in Delaware in 1984 under the name HealthMate, Inc.
("HealthMate"), as the successor to HealthMate of Illinois, Inc. and Lixiscope
of America, Inc., which were incorporated in Illinois in 1982 and 1981,
respectively. The mailing address of FluoroScan's principal executive offices
is: 650-B Anthony Trail, Northbrook, Illinois 60062, and its telephone number
is: (847)564-5400.

all adjournments or postponements thereof, the "Special Meeting").
 
PURPOSE OF THE SPECIAL MEETING
 
  At the Special Meeting, holders of FluoroScan Common Stock will be asked to
consider and vote upon a proposal to approve and adopt the Merger Agreement and
the Merger. Stockholders of FluoroScan will also consider and vote upon any
other matter that may properly come before the Special Meeting.
 
VOTE REQUIRED; RECORD DATE
 
  The affirmative vote of the holders of a majority of the outstanding shares
of FluoroScan Common Stock entitled to vote at the Special Meeting is required
for the approval and adoption of the Merger Agreement and the Merger. Holders
of FluoroScan Common Stock are entitled to one vote per share. Only holders of

outstanding shares of FluoroScan Common Stock as of the Record Date) in favor
of the Merger. Moreover, Larry S. Grossman and Arlen L. Issette, the Chief

agreements with Hologic pursuant to which they have agreed to vote, and have
granted Hologic irrevocable proxies with respect to, all shares of FluoroScan

                                   THE MERGER
 
EFFECTS OF THE MERGER
 
  The Merger will become effective after satisfaction of all conditions to the
Merger Agreement and on the date the Articles of Merger are duly filed with the
Secretary of State of the State of Delaware (the "Effective Time"). Assuming
all of the conditions to the Merger are fulfilled, it is expected that the
Effective Time will occur on August 29, 1996, or as soon thereafter as
practicable. Upon consummation of the Merger, FluoroScan will become a wholly-
owned subsidiary of Hologic, and the stockholders of FluoroScan will become
stockholders of Hologic.
 
CONVERSION OF SHARES
 
  At the Effective Time, each share of FluoroScan Common Stock issued and
outstanding immediately prior to the Effective Time will be converted into the
right to receive .31069 shares of Hologic Common Stock, subject to adjustment
as described below (the "Conversion Ratio"). If the average closing price per
share of the Hologic Common Stock as quoted on the Nasdaq National Market for
the ten trading days ending two business days prior to the Effective Time (the
"Average Market Value") is greater than $50.29, the Conversion Ratio shall be
adjusted to equal $15.63 divided by the Average Market Value, and (ii) if the
Average Market Value is less than $30.17, at Hologic's election the Conversion
Ratio will be adjusted to equal $9.37 divided by the Average Market Value. If
the Average Market Value is less than $30.17, and Hologic does not elect to
adjust the Conversion Ratio, the Board of Directors of FluoroScan may elect to
terminate the Merger Agreement and the Merger. Hologic will not be required to
issue fractional shares of Hologic Common Stock in connection with the Merger.
In lieu of any fractional shares of Hologic Common Stock that would otherwise
be issued to FluoroScan stockholders, such stockholders will receive cash in
the amount of the Conversion Ratio multiplied by the Average Market Value.
Holders of FluoroScan Common Stock shall also have the right to receive
together with each share of Hologic Common Stock issued in connection with the
Merger, an associated common stock purchase right ("Hologic Purchase Right")
pursuant to the Rights Agreement dated as of December 22, 1992, as amended (the
"Rights Agreement"), between Hologic and American Stock Transfer & Trust
Company, as Rights Agent. References herein to Hologic Common Stock issuable in
the Merger shall be deemed to include the associated Hologic Purchase Rights.
See "The Merger and Related Transactions--General," "--Conversion of Shares;
Procedures for Exchange of Certificates."
 
CONVERSION OF OPTIONS
 
  At the Effective Time, each outstanding option to purchase FluoroScan Common
Stock (the "FluoroScan Plan Options") granted under FluoroScan's 1994 Amended
and Restated Stock Incentive Plan, as amended, (the "FluoroScan 1994 Plan"),
the 1995 Stock Incentive Plan (the "FluoroScan 1995 Plan") and the 1994
Directors Stock Option Plan (the "FluoroScan Directors Plan" and, collectively,
the "FluoroScan Option Plans"), and each option to purchase FluoroScan units
(the "FluoroScan Units"), with each FluoroScan Unit consisting of one share of
FluoroScan Common Stock and a warrant to purchase one share of FluoroScan
Common Stock (the "FluoroScan Unit Options," collectively with the FluoroScan
Plan Options, the "FluoroScan Options"), will be assumed by Hologic. Each
FluoroScan Option so assumed shall continue to have, and be subject to, the
same terms and conditions set forth in the FluoroScan Option prior to the
Effective Time, except that (a) each FluoroScan Plan Option will be exercisable
for that number of whole shares of Hologic Common Stock equal to the number of
shares of FluoroScan Common Stock that were issuable upon exercise of the
FluoroScan Plan Option immediately prior to the Effective Time multiplied by
the Conversion Ratio, and (b) each FluoroScan Unit Option shall be exercisable
for that number of whole Hologic units, with each Hologic unit consisting of
one share of Hologic Common Stock and a warrant to purchase one share of
Hologic Common Stock (a "Hologic Unit"), equal to the number of FluoroScan
Units that were issuable upon exercise of the FluoroScan Unit Option
immediately prior to the Effective Time multiplied by the Conversion Ratio, and
(c) the per share exercise price for the Hologic Common Stock and the Hologic
Units issuable upon exercise of the FluoroScan
 
                                       7
<PAGE>
 
Plan Options, the FluoroScan Unit Options and the warrants included in the
FluoroScan Units ("FluoroScan Unit Warrants") will be equal to the quotient
determined by dividing the exercise price at which such option or warrant was

OPINION OF FLUOROSCAN'S FINANCIAL ADVISOR
 
  Rodman & Renshaw, Inc. ("Rodman") has delivered its written opinion to the
FluoroScan Board of Directors dated July 18, 1996 that, as of the date of such
opinion and subject to certain assumptions, factors and limitations set forth
in such opinion, the Conversion Ratio to be offered to FluoroScan's
stockholders is fair, from a financial point of view, to such stockholders. A
copy of the opinion of Rodman, which sets forth the assumptions made, matters
considered and limitations on the review undertaken by Rodman, is attached as
Appendix B to this Proxy Statement/Prospectus. Stockholders of FluoroScan are
urged to read the opinion carefully and in its entirety. See "The Merger and
Related Transactions--Opinion of FluoroScan's Financial Advisor."
 
RECOMMENDATION OF THE FLUOROSCAN BOARD OF DIRECTORS
 
  The FluoroScan Board of Directors has unanimously determined that the Merger
is fair to, and in the best interests of, the FluoroScan stockholders and has
approved the Merger Agreement and the Merger. The FluoroScan Board of Directors
unanimously recommends that FluoroScan's stockholders approve and adopt the
Merger Agreement and the Merger. See "The Merger and Related Transactions--
Background of the Merger," "--FluoroScan's Reasons for the Merger," "--
Recommendation of FluoroScan Board of Directors," and "--Interests of Certain
Persons in the Merger."
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
  In considering the recommendation of the FluoroScan Board of Directors with
respect to the Merger Agreement and the transactions contemplated thereby,
stockholders should be aware that certain members of FluoroScan's management
(some of whom are members of FluoroScan's Board of Directors) and the
FluoroScan Board of Directors have certain interests in the Merger in addition
to their interests as stockholders of FluoroScan generally. Among other things,
the Merger Agreement includes provisions obligating Hologic to preserve and
assume certain indemnification rights and benefits of, and to provide liability
insurance coverage for, the directors of FluoroScan, and to become obligated
under Amended and Restated Employment Agreements with Larry S. Grossman and
Arlen L. Issette, the Chief Executive Officer and President of FluoroScan,
respectively, which were entered into on July 18, 1996 upon execution of the
Merger Agreement, pursuant to which Messrs. Grossman and Issette will continue
to serve as Chief Executive Officer and President of FluoroScan, respectively,
remain as directors of FluoroScan and become Vice Presidents of Hologic
following the consummation of the Merger. In addition, Mr. Grossman will also
become a director of Hologic at the Effective Time. In addition, the
outstanding Director Options to purchase, in the aggregate, 72,000 shares of
Fluoroscan Common Stock will entitle the holders to receive cash payments equal
to the fair market value of such shares minus their exercise price following
the Merger. Each of the holders of Director Options has agreed to waive his
right to such payment and have his Director Options assumed by Hologic in the
event that such cash payments would cause the Merger not to qualify as a
pooling of interests for accounting and financial reporting purposes. See "The
Merger and Related Transactions--Interests of Certain Persons in the Merger."
 
OPTION AGREEMENT WITH CERTAIN STOCKHOLDERS
 
  As a condition to entering into the Merger Agreement, on July 18, 1996,
Hologic entered into a Stockholder Option Agreement with Messrs. Grossman and
Issette (the "Stockholder Option Agreement"). Under the Stockholder Option
Agreement, Messrs. Grossman and Issette have granted Hologic an option, under
certain circumstances if the Merger is not consummated, to purchase the shares
of FluoroScan Common Stock held by them at an exercise price equal to the
Conversion Ratio. The number of shares of FluoroScan Common Stock
 
                                       8
<PAGE>
 
covered by the Stockholder Option Agreements is 1,467,152 which constitutes
approximately 31.7% of the number of outstanding shares of FluoroScan Common
Stock on the Record Date. See "The Merger and Related Transactions--Option
Agreement with Certain Stockholders."
 
CONDITIONS TO THE MERGER
 
  In addition to the requirement that the stockholders of FluoroScan approve
the Merger, consummation of the Merger is subject to a number of other
conditions that, if not satisfied or waived, may result in the termination of
the Merger Agreement. Each party's obligation to consummate the Merger is
conditioned upon, among other things, the accuracy of the other party's
representations, the other party's performance of its covenants, absence of
certain litigation, absence of material adverse change to the business of the
other party, and favorable legal opinions to the effect that the Merger will be
treated for federal income tax purposes as a tax-free reorganization. In
addition, Hologic may terminate the Merger Agreement if it does not receive
favorable letters from the respective independent accountants of Hologic and
FluoroScan that the Merger will qualify as a pooling of interests for
accounting and financial reporting purposes. See "The Merger and Related
Transactions--Conditions to the Merger."
 
TERMINATION; TERMINATION FEES AND EXPENSES
 
  The Merger Agreement is subject to termination: (i) by the mutual consent of
the Boards of Directors of Hologic and FluoroScan, (ii) by either party, if,
without the fault of such terminating party, the Merger shall not have been
consummated on or before November 30, 1996, (iii) by either party, if there
shall be issued a final order by any court of competent jurisdiction or other
governmental body in the United States restraining, enjoining or otherwise
prohibiting the Merger, (iv) by either party if the Merger Agreement shall fail
to receive the requisite approval of the stockholders of FluoroScan, (v) by the
Board of Directors of FluoroScan if the Average Market Value of the Hologic
Common Stock is less than $30.17 and Hologic does not elect to adjust the
Conversion Ratio to equal $9.37 divided by the Average Market Value, and (vi)
in certain other circumstances. Under certain circumstances, if the Merger
Agreement is terminated, Hologic may be entitled to receive from FluoroScan a
termination fee of $2.4 million and the payment of up to $1.5 million for fees
and expenses relating to the transaction. Under certain other circumstances, if
the Merger Agreement is terminated, Hologic or FluoroScan may be entitled to
receive from the other the payment of up to $1.5 million for fees and expenses
relating to the transaction. See "The Merger and Related Transactions--
Termination" and "--Termination Fee and Expenses."
 
CERTAIN FEDERAL INCOME TAX MATTERS
 
  The Merger is intended to qualify as a reorganization within the meaning of
Section 368(a) of the Internal Revenue Code of 1986, as amended (the "Code"). A
condition to the obligations of Hologic and FluoroScan to consummate the Merger
is the receipt by them of an opinion of legal counsel to the effect that, among
other things: (i) the Merger will qualify as a reorganization within the
meaning of Section 368(a) of the Code: (ii) each of Hologic, Merger Sub and
FluoroScan will be a party to the reorganization within the meaning of Section
368(b) of the Code; and (iii) no gain or loss will be recognized by a holder of
FluoroScan Common Stock as a result of the Merger with respect to shares of
FluoroScan Common Stock converted solely into shares of Hologic Common Stock
(except with respect to cash, if any, received in lieu of fractional share
interests). However, consummation of the Merger is not conditioned upon the
receipt of a private letter ruling from the Internal Revenue Service as to the
tax consequences of Merger. See "The Merger and Related Transactions--Certain
Federal Income Tax Matters."
 
ACCOUNTING TREATMENT
 
  The Merger is intended to qualify as a pooling of interests for accounting
and financial reporting purposes. Hologic and FluoroScan have been advised by,
and will receive letters from Arthur Andersen LLP, Hologic's independent
accountants, and BDO Seidman, LLP, FluoroScan's independent accountants, to the
effect that, the Merger will qualify as a pooling of interests for accounting
and financial reporting purposes. Under this method
 
                                       9
<PAGE>
 
of accounting, the recorded assets and liabilities of Hologic and FluoroScan
will be carried forward to Hologic at their recorded amounts, the consolidated
income of Hologic will include income of Hologic and FluoroScan for the entire
fiscal year in which the combination occurs, and the reported income of the
separate companies for prior periods will be combined and restated as
consolidated income of Hologic.
 
REGULATORY APPROVALS
 
  Neither Hologic nor FluoroScan is aware of any governmental or regulatory
approvals required for the consummation of the Merger other than (i) compliance
with the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the
" HSR Act"), as described below, (ii) compliance with applicable securities
laws and (iii) certain filings under Delaware Law.
 
  The Merger is subject to the HSR Act and the rules and regulations
thereunder, which provide that certain transactions may not be consummated
until required information and materials have been furnished to the Antitrust
Division of the Department of Justice (the "Antitrust Division") and the
Federal Trade Commission (the "FTC") and certain waiting periods have been
expired or been terminated. On August 1, 1996, Hologic and FluoroScan filed the
required information and materials with the Antitrust Division and FTC and
requested early termination of the waiting period under the HSR Act. See "The
Merger and Related Transactions--Regulatory Approvals."
 
NO APPRAISAL RIGHTS
 
  Under Delaware Law, the holders of FluoroScan Common Stock are not entitled
to any appraisal rights in connection with the Merger. See "The Merger and
Related Transactions--No Appraisal Rights."
 
COMPARATIVE RIGHTS OF STOCKHOLDERS
 
  See "Comparison of Rights of Stockholders of Hologic and FluoroScan" for a
summary of certain differences between the rights of holders of Hologic Common
Stock and the rights of holders of FluoroScan Common Stock.
 
EXCHANGE OF STOCK CERTIFICATES
 
  If the Merger becomes effective, the holders of record of FluoroScan Common
Stock will be required to surrender their stock certificates in exchange for
certificates representing shares of Hologic Common Stock and a cash payment in
lieu of fractional shares, if any. Certificates should not be surrendered at
this time. See "The Merger and Related Transactions--Conversion of Shares;
Procedures for Exchange of Certificates."

                                 RISK FACTORS
 
  In addition to the other information in this Proxy Statement/Prospectus, the
following risk factors should be considered carefully by the FluoroScan
stockholders in determining whether to vote for the approval and adoption of
the Merger Agreement and the Merger, and the acquisition of the securities
offered hereby. For the period following the Merger, references to the
business and operations of Hologic should be considered to refer to Hologic
and its subsidiaries, including FluoroScan, unless the context otherwise
requires. Forward-looking statements made in this section and elsewhere in
this Proxy Statement/Prospectus are made pursuant to the safe harbor
provisions of the Private Securities Litigation Reform Act of 1995. All
forward-looking statements involve risks and uncertainties, and actual results
could differ materially from those set forth in the forward-looking statements
contained herein for a variety of reasons, including but not limited to the
risks outlined in this section.
 
RISKS RELATING TO THE MERGER
 
  Integration of the Two Companies. Hologic and FluoroScan have each entered
into the Merger Agreement with the expectation that the Merger will benefit
both Hologic and FluoroScan. See "The Merger--Reasons for the Merger."
Achieving the anticipated benefits from the Merger will depend in part upon
whether the businesses of Hologic and FluoroScan can be managed and
coordinated in a timely, efficient and effective manner, and there can be no
assurance that this will occur. The difficulties of such integration may be
increased by the necessity of coordinating geographically separated
organizations (Hologic and FluoroScan are based in the Boston and Chicago
metropolitan area, respectively) and integrating personnel with disparate
background and corporate cultures. The integration process will require the
dedication of management resources that will detract attention from the daily
business of Hologic and FluoroScan. In addition, Hologic anticipates
integrating FluoroScan products into its foreign sales and distribution
channels. The risk inherent in such integration may be greater than those
associated with the integration of FluoroScan's and Hologic's domestic
operations. See "Risk Factors--Reliance on Foreign Sales." The timing and
manner of the implementation of decisions made with respect to the ongoing
business of the combined companies following the Merger will materially affect
the operations of Hologic and FluoroScan. This integration process may cause
an interruption of, or a loss of momentum in, the activities of either or both
of the businesses of Hologic and FluoroScan, which could have a material
adverse effect on Hologic's business.
 
  Transaction Costs. Hologic and FluoroScan estimate that they will incur
direct transaction costs of approximately $1.8 million associated with the
Merger. These transaction costs will be expensed in the period incurred under
the pooling-of-interests method of accounting for business combinations. As a
result, the earnings of the combined entity will be adversely affected. This
decrease in Hologic's earnings may have a significant impact on the market
price of Hologic Common Stock. This amount is a preliminary estimate only and
therefore subject to change. There can be no assurance that Hologic and
FluoroScan will not incur additional charges to reflect costs associated with
the Merger.
 
RISKS RELATING TO HOLOGIC AND FLUOROSCAN
 
  The risk factors in this subsection apply to each of Hologic and FluoroScan
individually, where appropriate, and also are expected to apply to Hologic
following the consummation of the Merger.
 
  Dependence of Product Sales on Availability and Acceptance of New Drug
Therapies. Hologic believes that it is important for the continued growth of
its sales of bone densitometers and other related products, that the efficacy
of new drug therapies to treat osteoporosis and other bone disorders be
demonstrated, that broadened regulatory approval of those therapies be granted
in the United States and elsewhere, and once approved, that these new drug
therapies gain acceptance. Similarly, FluoroScan believes that it is important
for the continued growth of sales of its products that the efficacy of
therapies that could broaden the use of minimally invasive orthopedic surgery
such as synthetic bone materials be demonstrated, that broadened regulatory
approval of those therapies be granted in the United States and elsewhere, and
once approved, that these new therapies gain acceptance. There can be no
assurance that any therapies under development or in clinical trials will
prove to be
 
                                      16
<PAGE>
 
effective, obtain FDA approval or, once approved, gain acceptance. The failure
of one or more of these therapies to gain wide acceptance, or the failure of
new therapies to be approved and gain acceptance, could have a material
adverse effect on Hologic's business.
 
  Uncertainty of Health Care Reform. Health care reform and medical cost
containment have received significant attention in the United States and many
foreign countries. Certain reform proposals and cost containment measurers
could limit the use of Hologic's and FluoroScan's products, reduce
reimbursement available for such use, or adversely affect the use of new
therapies for which Hologic's or FluoroScan's products may be targeted. As a
result, such reforms or cost containment measures could materially and
adversely affect sales of each of Hologic's and FluoroScan's products.
Uncertainty in the medical community regarding the nature and effect of
proposed health care reforms and cost containment measures may also have a
material adverse effect on Hologic's business.
 
  Third Party Reimbursement for Bone Density Examinations. Reimbursement for
the use of DXA bone densitometers has been approved by health care insurance
systems in the United States and many foreign countries, including Belgium,
Brazil, Canada, Germany, Greece, Japan, South Korea, Spain and Switzerland. In
the United States, DXA examinations are paid for by many private third party
insurers. In addition, the Health Care Finance Administration ("HCFA"), which
establishes guidelines for the reimbursement of health care providers treating
Medicare and Medicaid patients, has recommended reimbursement for DXA
examinations. The actual reimbursement amounts provided for DXA examinations
is determined by the individual state Medicare carriers. As of December 1995,
several of the more populous states, including California, Connecticut, New
York, New Jersey and Pennsylvania, had no or only partial reimbursement of DXA
examinations. Hologic believes that it is important for the continued growth
of sales of Hologic's DXA bone densitometers in the United States and
internationally that reimbursement for bone density examinations be retained
and broadened. A reduction in reimbursement levels for Hologic's products
could have a material adverse effect on Hologic's business.
 
  Developing Markets; Need to Broaden Market Acceptance. The continued success
of Hologic's products that address the clinical market for the early diagnosis
and monitoring of osteoporosis, will depend upon the acceptance and adoption
of newly introduced and emerging drug therapies to treat osteoporosis by the
broad market of primary care providers, such as gynecologists and family
physicians, and Hologic's ability to broaden sales of its products to these
physician groups. In order to penetrate this market more effectively, Hologic
has expanded its sales and marketing activities, including increasing its
sales force, advertising and participation in trade shows. Historically,
FluoroScan has marketed its products to hospitals and surgery centers for use
by orthopedic surgeons in the operating room. The continued success of
FluoroScan's products will be dependent upon its ability to broaden its sales
to orthopedic and podiatric physician groups. There can be no assurance that
either Hologic or FluoroScan will be successful in obtaining broader market
acceptance for its products. Failure to do so could have a material adverse
effect on Hologic's business.
 
  Product Development; Uncertainty of Market Acceptance. Hologic's and
FluoroScan's success will depend upon their ability to enhance their existing
products, to develop new products to meet regulatory and customer requirements
and to achieve market acceptance. Hologic is developing an enhanced ultrasound
bone analyzer, the Sahara and, together with Serex, Inc., a diagnostic strip
test to detect biochemical markers that indicate the rate of a patient's bone
loss. FluoroScan is developing a new generation of its FluoroScan imaging
system, including a medical version of the FluoroScan II and a model with a
six-inch field-of-view. The development of these products will be subject to
all of the risks associated with new product development, including
unanticipated delays, expenses, technical problems or other difficulties that
could result in the abandonment or substantial change in the commercialization
of these new products. Given the uncertainties inherent in new product
development and introduction, there can be no assurance that Hologic or
FluoroScan will be successful in introducing products or product enhancements
on a timely basis, if at all, or that Hologic or FluoroScan will be able to
market these products and product enhancements once developed. Failure to do
so could have a material adverse effect on Hologic's business.
 
 
                                      17
<PAGE>
 
  Obsolescence and Rapid Technological Change. The markets for Hologic's and
FluoroScan's products are highly competitive and subject to rapid
technological change and evolving industry requirements and standards. Hologic
and FluoroScan believe that these trends will continue into the foreseeable
future. Several companies have developed or are expected to develop DXA bone
densitometry systems or other products that measure or assess bone density or
bone mineral status, which compete, or will compete, with Hologic's products.
These other systems include single photon absorptiometry, radiographic
absorptionetry, quantitative computed topography, ultrasound and biochemical
markers. Although Hologic believes that DXA technology is more precise than
competing technologies and is capable of scanning a broader range of sites,
certain competing technologies have cost or other advantages which may limit
Hologic's DXA market. Hologic's products may also compete with sales of used
and refurbished systems. In addition, many companies, research institutions
and universities may be working in a number of engineering and radiology
disciplines similar to those being used and developed by FluoroScan. As a
result, FluoroScan's products may become subject to competition from products
using technologies other than those developed by FlouroScan, which may render
FluoroScan's products obsolete or less attractive to customers if FluoroScan
cannot participate in such new technologies. No assurance can be given that
continuing improvements in current or new technologies will not make them
technically equivalent or superior to Hologic's or FluoroScan's technology, in
addition to providing cost or other advantages.
 
  Competition. Hologic competes directly with a number of companies with
significant financial resources, including Lunar, Norland Medical Systems,
Aloha and Hitachi, each of which has developed DXA systems to measure bone
density. FluoroScan competes directly with a limited number of companies
including Xi Tec, Lunar, OEC Medical and Lixi. Xi Tec manufactures products
comparable to FluoroScan's pursuant to a sublicense from FluoroScan which
expires in July 1997. OEC Medical and Lunar each manufacture small C-Arm
imaging systems that do not use FluoroScans patented technology. Lixi
manufactures an X-ray tube version, Lixiscope, only for the industrial
marketplace. FluoroScan also competes indirectly with manufacturers of
conventional C-Arm image intensifiers including Philips, Siemans, General
Electric, OEC Medical, Fischer Imaging and Picker International. These
competitors have substantially greater financial and marketing resources than
Hologic and FluoroScan. There can be no assurance that either Hologic or
FluoroScan will be able to compete successfully.
 
  Quarterly Fluctuations in Operating Results. Hologic's and FluoroScan's
results of operations have been and may continue to be subject to significant
quarterly variation. The results for a particular quarter may vary due to a
number of factors including the overall state of health care and cost
containment efforts, the development status and demand for drug therapies to
treat osteoporosis, economic conditions in Hologic's and FluoroScan's markets,
the timing of orders, the timing of expenditures in anticipation of future
sales, the mix of products sold by Hologic and FluoroScan, the introduction of
new products and product enhancements by Hologic, FluoroScan or their
respective competitors, and pricing and other competitive conditions. Hologic
also believes that its sales in Europe may be seasonal, with reduced orders in
the summer months reflecting summer vacation schedules. Customers may also
cancel or reschedule shipments and production difficulties could delay
shipments. Any of these factors also could materially adversely affect
Hologic's annual results of operations.
 
  No Assurance that New Products Will Receive FDA or Foreign Regulatory
Clearances. Medical devices cannot be marketed in the United States without
clearance or approval by the FDA. Medical devices sold in the United States
must also be manufactured in compliance with FDA Good Manufacturing Practices,
which regulate the design, manufacture, packing, storage and installation of
medical devices. Moreover, medical devices are required to comply with FDA
regulations relating to investigational research, labeling and post-market
reporting. States may also regulate the manufacture, sale and use of medical
devices, particularly those that employ X-ray technology. Hologic's and
FluoroScan's products are also subject to approval and regulation by certain
foreign regulatory and safety agencies. The process of obtaining clearances
and approvals can be costly and time-consuming. Moreover, any approvals or
clearances, once obtained, can be withdrawn or modified. Hologic and
FluoroScan have obtained all necessary FDA marketing clearances for Hologic's
DXA bone densitometers and FluoroScan's FluoroScan System under the less
stringent 510(k) marketing clearance procedure. Hologic believes that its
ultrasound products and over-the-counter biochemical marker strip test under
development may
 
                                      18
<PAGE>
 
require the more stringent and time consuming FDA premarket approval to be
marketed in the United States. Delay or inability to obtain any necessary
United States or foreign clearances or approvals for Hologic's or FluoroScan's
products could have a material adverse effect on Hologic's business.
 
  Reliance on Serex for the Development of Biochemical Marker Strip
Test. Hologic has entered into a research and development agreement with Serex
to develop biochemical marker strip tests to monitor bone resorption. Serex is
a relatively small company with limited resources and limited operating
history. There can be no assurance that Serex will be able to meet its
obligations under this agreement or otherwise be successful in developing the
strip test on a timely basis or within budget, if at all. Any such failure on
the part of Serex could have a material adverse effect on Hologic's future
prospects.
 
  Reliance on Foreign Sales; Restriction on FluoroScan's Foreign Sales. In the
six month period ending March 30, 1996 and in fiscal 1995, foreign sales
accounted for approximately 56% and 75%, respectively, of Hologic's product
sales. Hologic maintains sales and service offices in Belgium, France and
Spain. The expenses and sales of these offices are denominated in local
currencies. Hologic anticipates that foreign sales and foreign denominated
sales will continue to account for a significant portion of Hologic's total
sales, which will result in a significant portion of Hologic's revenues being
subject to risks associated with foreign sales, including risks of exchange
rate fluctuations, limitations on foreign sales of high technology products
and other United States and foreign regulatory requirements and policy
changes, political and economic instability, difficulties in accounts
receivable collection, difficulties in managing distributors or
representatives and seasonality of sales. Moreover, FluoroScan's technology is
governed by the International Traffic in Arms Regulations of the United States
Department of State. As a result, the export of FluoroScan Systems to certain
countries may be limited or prohibited. Hologic has hedged its foreign
currency exposure by borrowing funds in local European currencies to pay the
expenses of its foreign offices. There can be no assurance that these hedging
activities will be successful, or that exchange rate fluctuations or other
risks associated with international sales and operations will not have a
material adverse effect on Hologic's business.
 
  Dependence on Third Party Distributors; Significant Customer. For its sales
and service activities outside of the United States, Canada and certain
European countries, Hologic is primarily dependent upon third party
distributors. In the first six months of fiscal 1996 and in fiscal 1995,
Hologic's sales to its exclusive Japanese distributor, Toyo Medic Co., Ltd.
("Toyo Medic"), accounted for 20% of product sales. There can be no assurance
that Toyo Medic or any of Hologic's other distributors will continue to
provide sales and services for Hologic at acceptable levels, if at all, or
that Hologic would be able to replace any distributors on terms as
advantageous to Hologic should any of its existing arrangements terminate.
Further, there can be no assurance that Hologic will be able to make
arrangements with additional distributors to access new markets. Material
adverse changes in the relationship between Hologic and its distributors,
including the loss of Toyo Medic as a distributor or an adverse change in the
relationship between Hologic and Toyo Medic, or the failure of Hologic to
enter into advantageous arrangements with distributors in new markets, could
have a material adverse effect on Hologic's business.
 
  Uncertainty of Patent and Proprietary Rights Protection. Hologic relies upon
trade secrets and patents to protect its technology. Hologic has obtained 12
patents, licensed five patents and has pending 18 patent applications in the
United States relating to its DXA technology, and has obtained three patents,
licensed four patents and has pending two patent applications in the United
States relating to its ultrasound technology. Hologic has obtained or applied
for corresponding patents and patent applications for certain of these patents
and patent applications for certain foreign countries. There can be no
assurance that any of Hologic's patent applications will be granted or that
any patent or patent application will provide significant protection for
Hologic's products and technology. Moreover, there can be no assurance that
foreign intellectual property laws will protect Hologic's intellectual
property rights. In the absence of significant patent protection, Hologic may
be vulnerable to competitors who attempt to copy Hologic's products, processes
or technology.
 
  Hologic had been involved in extensive patent litigation with Lunar, with
each party claiming that the other is infringing certain patents held by the
other. This litigation was settled by agreement dated November 22, 1995.
 
                                      19
<PAGE>
 
The agreement provides for certain royalties to be paid by each party to the
other for future sales of products using certain defined technologies. Hologic
does not believe that amounts to be paid by either party under this
arrangement will be material. The agreement also provides that neither party
will engage the other party in patent litigation relating to these
technologies for a period of ten years following the date of the agreement,
regardless of the infringement claimed and regardless of whether the
technology in question currently exists or is developed or acquired by the
other party in the future. There can be no assurance that Lunar will not use
Hologic's technology during this ten-year period in a manner that would
materially and adversely affect Hologic's business.
 
  FluoroScan has two licenses from NASA to use and develop certain technology
that is used in its products and that are the subject of three patents held by
NASA. FluoroScan's license is exclusive in the United States. However, under
FluoroScan's license agreement with NASA, NASA retains the right to use its
technologies in connection with devices that it produces, including devices
that may be produced and marketed by NASA in direct competition with
FluoroScan. NASA also has the right to circumvent the exclusivity of the
license agreement if, in NASA's opinion, such circumvention is required to
serve the public good and the national interest of the United States, and
FluoroScan cannot serve such functions. Moreover, FluoroScan's license
agreement with NASA is exclusive only in the United States and its
territories. Accordingly, NASA retains the right to license its technologies
to others outside of the United States, where such technologies are patented
or can be patented. The technology covered by the NASA patents is not patented
in many foreign countries and may therefore not be protectable or may be
cumbersome and expensive to enforce in such countries. Therefore, a competitor
in one of these countries could reverse engineer FluoroScan's products and
manufacture and sell products in direct competition with FluoroScan outside
the United States. One of the patents, covering important technology
incorporated in FluoroScan's products, expires in July 1997 and the other two
patents expire in 2003. These patents previously had expiration dates in
February 1996 and 2002, but were extended as a result of the passage of the
General Agreement on Tariff and Trade ("GATT"). Upon expiration of a patent,
all of the technology covered by these patents will be accessible to potential
competitors, which could have a material adverse effect on FluoroScan's
business.
 
  Acquisition Risks. Hologic expects that in addition to internal development
it will continue to seek to expand its products and technology in part through
acquisitions or strategic alliances in complimentary markets, including other
diagnostic or imaging markets, or other women's health care markets. There can
be no assurance Hologic will be successful in identifying, acquiring and
developing products and technology. If any potential acquisition opportunities
are identified, there can be no assurance that Hologic will consummate such
acquisitions or successfully integrate the technology or businesses acquired
into Hologic. Acquisitions involve a number of special risks, including the
diversion of management's attention, the assimilation of the operations and
personnel of the acquired companies, the incorporation of acquired products
into existing product lines, adverse short-term effects on reported operating
results, the amortization of acquired intangible assets, the loss of key
employees of the acquired company or business and the difficulty of presenting
a unified corporate image. No assurance can be given that any acquisition by
Hologic will or will not occur, that if an acquisition does occur it will not
materially and adversely affect Hologic or that any such acquisition will be
successful in enhancing Hologic's business. If the operations of the acquired
company do not meet expectations, Hologic may be required to restructure the
acquired business or write off the value of some or all of the assets of the
acquired business.
 
  Attraction and Retention of Key Personnel. The future success of Hologic
will depend in large part on the continued services of its executive officers,
including the executive officers of FluoroScan, as well as Hologic's ability
to attract and retain other highly qualified and well-trained managerial and
technical personnel. There may be only a limited number of persons with the
requisite skills to serve in these positions and it may become increasingly
difficult for Hologic to hire such personnel. Competition for such personnel
is intense, and there can be no assurance that Hologic will be able to attract
and retain personnel necessary for the development of its business. FluoroScan
has been, and for the foreseeable future will continue to be, dependent upon
the services of Larry S. Grossman and Arlene L. Issette, its Chief Executive
Officer and President, respectively. Hologic has entered into Amended and
Restated Employment Agreements with Messrs. Grossman and Issette which expire
 
                                      20
<PAGE>
 
in February 1999. There can be no assurance that either or both of Messrs.
Grossman and Issette will continue their employment after the expiration of
their employment agreements or that they will not terminate their employment
prior to such expiration. S. David Ellenbogen and Jay A. Stein, the Chief
Executive Officer and Senior Vice President, respectively, of Hologic, also
serve in similar positions at Vivid Technologies, Inc. ("Vivid"). Under a
management agreement between Hologic and Vivid, Hologic has agreed to provide
management services to Vivid, including the part-time assistance of Mr.
Ellenbogen and Dr. Stein. Mr. Ellenbogen and Dr. Stein typically devote up to
approximately 16 and eight hours per week, respectively, to Vivid. See
"Certain Transactions."
 
  Product Liability. Hologic's and FluoroScan's businesses involve the risk of
product liability claims inherent to the medical device business. Hologic
currently maintains product liability insurance with an aggregate coverage
limit of $6.0 million per year, subject to certain deductibles and exclusions.
FluoroScan currently maintains product liability insurance with a coverage
limit of $1.0 million per occurrence, with an aggregate limit of $2.0 million
per year, subject to certain deductibles and exclusions. There can be no
assurance that Hologic's and FluoroScan's insurance will be sufficient to
protect them from product liability claims, or that product liability
insurance will be available to Hologic at a reasonable cost, if at all, in the
future. An underinsured or uninsured claim could have a material adverse
effect on Hologic's financial condition.
 
  Anti-takeover Provisions; Management Control. Hologic's Certificate of
Incorporation and By-laws include certain provisions that may have the effect
of discouraging or preventing a change in control of Hologic. In addition,
Hologic made a rights distribution in December 1992 that could also have the
effect of discouraging or preventing a change in control of Hologic. These
provisions could limit the price that stockholders of Hologic might receive in
the future for shares of Hologic Common Stock. See "Comparison of Rights of
Stockholders of Hologic and FluoroScan" and "Description of Hologic Capital
Stock."
 
  Volatility of Hologic Stock Price. The market price of Hologic Common Stock
has been and may continue to be highly volatile. From January 1, 1996 to
August 5, 1996, the price per share of Hologic's Common Stock has ranged from
a high of $49.50 to a low of $17.25. Factors such as quarterly fluctuations in
Hologic's results of operations, the announcement of technological innovations
or new products by Hologic or its competitors, variations in anticipated or
actual operating results, market conditions, and general economic conditions
may have a significant impact on the market price of Hologic Common Stock.

person or by proxy.
 
INTENTIONS AND AGREEMENTS TO VOTE
 
  Each of the directors and executive officers of FluoroScan has advised
FluoroScan that he intends to vote all shares of FluoroScan Common Stock over
which he has voting control (a total of 1,701,428 or approximately 36.8% of
the outstanding shares of FluoroScan Common Stock as of the Record Date) in
favor of the Merger. Moreover, Larry S. Grossman and Arlen L. Issette, the
Chief Executive Officer and President of FluoroScan, respectively, have
entered into agreements with Hologic pursuant to which they have agreed to
vote and have granted Hologic irrevocable proxies with respect to all shares
of FluoroScan Common Stock over which they hold or have voting control (a
total of 1,697,028 shares, or approximately 36.7% of the outstanding shares of
FluoroScan Common Stock as of the Record Date) in favor of the Merger.
 
VOTING OF PROXIES
 
  A form of proxy for voting shares of FluoroScan Common Stock at the Special
Meeting is enclosed. All shares of FluoroScan Common Stock which are entitled
to vote and are represented at the Special Meeting by properly executed
proxies received prior to or at the Special Meeting, and not duly and timely
revoked, will be voted at the Special Meeting in accordance with the
instructions indicated on such proxies. IF NO INSTRUCTIONS ARE INDICATED, SUCH
PROXIES WILL BE VOTED FOR APPROVAL AND ADOPTION OF THE MERGER AGREEMENT AND
THE MERGER. The Board of Directors of FluoroScan knows of no other matters to
be presented at the Special Meeting other than those described in this Proxy
Statement/Prospectus. If any other matters are properly presented at the
Special Meeting for consideration, including, among other things,
consideration of a motion to adjourn or postpone the Special Meeting to
another time and/or place (including, without limitation, for the purpose of
soliciting additional proxies), the persons named in the enclosed form of
proxy will have discretion to vote on such matters in accordance with their
best judgment.
 
  Any proxy given pursuant to this solicitation may be revoked by the person
giving it at any time before it is voted. Proxies may be revoked or superseded
by: (i) filing with the Secretary of FluoroScan at or before the taking of the
vote at the Special Meeting, a written notice of revocation bearing a later
date than the proxy; (ii) duly executing a later dated proxy relating to the
same shares and delivering it to the Secretary of FluoroScan before the taking
of the vote at the Special Meeting; or (iii) attending the Special Meeting and
voting in person (although attendance at the Special Meeting will not in and
of itself constitute a revocation of a proxy). Any written notice of
revocation or subsequent proxy should be sent so as to be delivered to
FluoroScan Imaging Systems, Inc., 650-B Anthony Trail, Northbrook, Illinois
60062, Attention: Secretary, or hand-delivered to the Secretary of FluoroScan,
at or before the taking of the vote at the Special Meeting.

VOTE REQUIRED
 
  The approval and adoption of the Merger Agreement and the Merger requires
the affirmative vote of the holders of at least a majority of the outstanding
shares of FluoroScan Common Stock entitled to vote thereon.
 
QUORUM; ABSTENTIONS AND BROKER NON-VOTES
 
  The presence, in person or by properly executed proxy, of the holders of
shares of FluoroScan Common Stock entitled to vote at the Special Meeting
representing a majority of the outstanding shares of FluoroScan Common Stock
as of the Record Date is necessary to constitute a quorum at the Special
Meeting. Abstentions and broker non-votes are each included in the
determination of the number of shares present for the purpose of determining
whether a quorum is present, and each is tabulated separately. In determining
whether the proposal relating to the approval and adoption of the Merger
Agreement and the Merger has been approved, abstentions and broker non-votes
will have the same effect as votes against the proposal.
 
SOLICITATION OF PROXIES AND EXPENSES
 
  FluoroScan will bear the cost of the solicitation of proxies in the enclosed
form from its stockholders, which solicitation will be primarily by use of the
mails. In addition to solicitation by use of the mails, proxies may be
solicited by directors, officers and employees of FluoroScan in person or by
telephone, telegram, facsimile transmission or other means of communication.
Such directors, officers and employees will not be additionally compensated,
but may be reimbursed for reasonable out-of-pocket expenses in connection with
such solicitation. Arrangements will also be made with custodians, nominees
and fiduciaries for forwarding of proxy solicitation materials to beneficial
owners of shares held of record by such custodians, nominees and fiduciaries,
and FluoroScan will reimburse such custodians, nominees and fiduciaries for
reasonable expenses incurred in connection therewith. FluoroScan has also
retained MacKenzie Partners, Inc. at an estimated cost of $4,000 plus
reimbursement of expenses, to assist in the solicitation of proxies by
telephone and by mail.
 
  THE FLUOROSCAN BOARD OF DIRECTORS HAS DETERMINED THAT THE MERGER IS IN THE
BEST INTERESTS OF FLUOROSCAN AND ITS STOCKHOLDERS AND HAS THEREFORE

                      THE MERGER AND RELATED TRANSACTIONS
 
  The following is a summary of the material features of the proposed Merger.
To the extent that it relates to the Merger Agreement, the following
description does not purport to be complete and is qualified in its entirety
by reference to the Merger Agreement, which is attached as Appendix A to this
Proxy Statement/Prospectus. All stockholders are urged to read the Merger
Agreement in its entirety.
 
GENERAL
 
  The Merger Agreement provides for the merger of the newly-formed Fenway
Acquisition Corp., a Delaware corporation and wholly-owned subsidiary of
Hologic ("Merger Sub"), with and into FluoroScan. FluoroScan will be the
surviving corporation in the Merger and will become a wholly-owned subsidiary
of Hologic as a result of the Merger.
 
  The current directors and officers of Hologic will continue to serve in
their current capacities following the Merger. The current officers of
FluoroScan are expected to continue to serve FluoroScan in their current
capacities following the Merger. Following the Merger, the Board of Directors
of FluoroScan is expected to consist of Larry S. Grossman and Arlen L.
Issette, the Chief Executive Officer and President of FluoroScan,
respectively, and three members appointed by Hologic. Messrs. Grossman and
Issette will also become Vice Presidents of Hologic, and Hologic has agreed to
elect Mr. Grossman to its Board of Directors upon the consummation of the
Merger. See "Hologic Management--Executive Officers and Directors." The
stockholders of FluoroScan will become stockholders of Hologic (as described
below) upon consummation of the Merger, and their rights as such will be
governed by the Hologic Certificate of Incorporation and By-laws and will
continue to be governed by Delaware Law. See "Comparison of Rights of
Stockholders of Hologic and FluoroScan" and "Description of Hologic Capital
Stock."
 
  Conversion of Shares. Upon consummation of the Merger, each share of
FluoroScan Common Stock issued and outstanding immediately prior to the
Effective Time will be converted into the right to receive .31069 shares of
Hologic Common Stock, subject to adjustment as set forth below (the
"Conversion Ratio"). If the average closing price per share of the Hologic
Common Stock as quoted on the Nasdaq National Market for the ten trading days
ending two business days prior to the Effective Time (the "Average Market
Value") is greater than $50.29, the Conversion Ratio shall be adjusted to
equal $15.63 divided by the Average Market Value. If the Average Market Value
is less than $30.17, at Hologic's election the Conversion Ratio will be
adjusted to equal $9.37 divided by the Average Market Value. If the Average
Market Value is less than $30.17 and Hologic does not elect to adjust the
Conversion Ratio, the Board of Directors of FluoroScan may elect to terminate
the Merger Agreement and the Merger. No fractional shares of Hologic Common
Stock will be issued pursuant to the Merger. In lieu of any fractional share
of Hologic Common Stock that would otherwise be issued to FluoroScan
stockholders pursuant to the Merger Agreement, such FluoroScan stockholders
will receive cash in an amount equal to such fractional share multiplied by
the Average Market Value. Holders of FluoroScan Common Stock shall also have
the right to receive together with each share of Hologic Common Stock issued
in the Merger, an associated common stock purchase right ("Hologic Purchase
Right") pursuant to the Rights Agreement dated as of December 22, 1992, as
amended (the "Rights Agreement"), between Hologic and American Stock Transfer
& Trust Company, as Rights Agent. References herein to the Hologic Common
Stock issuable in the Merger shall be deemed to include the associated Hologic
Purchase Rights.
 
  As of the Record Date, there were 4,622,894 shares of FluoroScan Common
Stock outstanding and 11,310,790 shares of Hologic Common Stock outstanding.
Assuming no adjustment to the Conversion Ratio, and without giving effect to
the issuance of any shares of FluoroScan Common Stock or Hologic Common Stock
after the Record Date, upon consummation of the Merger, the outstanding shares
of FluoroScan Common Stock would be converted into approximately 1,436,287
shares of Hologic Common Stock, representing approximately 11.3% of the
approximately 12,747,077 shares of Hologic Common Stock that would be
outstanding after the Merger, assuming no issuance of any other shares of
Hologic Common Stock or FluoroScan Common Stock after the Record Date.
 
 
                                      24

  Conversion of Options. Each outstanding option to purchase FluoroScan Common
Stock (the "FluoroScan Plan Options") granted under the FluoroScan Option
Plans, and each option to purchase a FluoroScan unit ("FluoroScan Unit"), with
each FluoroScan Unit consisting of one share of FluoroScan Common Stock and a
warrant to purchase one share of FluoroScan Common Stock (the "FluoroScan Unit
Options," collectively with the FluoroScan Plan Options, the "FluoroScan
Options"), will be assumed by Hologic. Each FluoroScan Option so assumed shall
continue to have, and be subject to, the same terms and conditions set forth
in the FluoroScan Option prior to the Effective Time, except that (a) each
FluoroScan Plan Option shall be exercisable for that number of whole shares of
Hologic Common Stock equal to the number of shares of FluoroScan Common Stock
that were issuable upon exercise of the FluoroScan Plan Option immediately
prior to the Effective Time multiplied by the Conversion Ratio, and (b) each
FluoroScan Unit Option shall be exercisable for that number of whole Hologic
units, with each Hologic unit consisting of one share of Hologic Common Stock
and a warrant to purchase one share of Hologic Common Stock (a "Hologic
Unit"), equal to the number of FluoroScan Units that were issuable upon
exercise of the FluoroScan Unit Option immediately prior to the Effective Time
multiplied by the Conversion Ratio, and (c) the per share exercise price for
the Hologic Common Stock and the Hologic Units issuable upon exercise of the
FluoroScan Plan Options, the FluoroScan Unit Options and the warrants included
in the FluoroScan Units (the "FluoroScan Unit Warrants") will be equal to the
quotient determined by dividing the exercise price at which such option or
warrant was exercisable immediately prior to the Effective Time by the
Conversion Ratio.
 
  As of the Record Date, there were (i) 957,800 shares of FluoroScan Common
Stock subject to outstanding FluoroScan Plan Options with exercise prices
ranging from $5.75 to $10.125 per share, (ii) 100,000 FluoroScan Units subject
to outstanding FluoroScan Unit Options with an exercise price of $10.50 per
FluoroScan Unit, and (iii) 100,000 shares of FluoroScan Common Stock subject
to the FluoroScan Unit Warrants, with an exercise price of $7.20 per share,
that are issuable upon exercise of FluoroScan Unit Options. Assuming no
adjustment to the Conversion Ratio and no exercise or grant of any FluoroScan
Options after the Record Date, upon consummation of the Merger (i) the
FluoroScan Plan Options would be converted into the right to purchase
approximately 297,600 shares of Hologic Common Stock at exercise prices
ranging from approximately $18.50 to $32.59 per share, (ii) the FluoroScan
Unit Options would be converted into the right to purchase approximately
31,069 Hologic Units, with an exercise price of approximately $33.80 per Unit,
and (iii) the FluoroScan Unit Warrants issuable upon exercise of the
FluoroScan Unit Options would be converted into the right to purchase
approximately 31,069 shares of Hologic Common Stock with an exercise price of
approximately $23.17 per share. Hologic has agreed to file and maintain the
effectiveness of a Registration Statement on Form S-8 under the Securities Act
with respect to all shares of Hologic Common Stock subject to FluoroScan Plan
Options to be assumed by Hologic that may be registered on Form S-8. In
addition, the holders of FluoroScan Unit Options will have demand and
piggyback registration rights with respect to the registration of the
underlying Hologic securities that will become subject to the FluoroScan Unit
Options upon their assumption by Hologic.
 
  As of the Record Date, there were 1,355,766 shares of Hologic Common Stock
subject to outstanding options, with exercise prices ranging from $.05 to
$45.25 per share.
 
BACKGROUND OF THE MERGER
 
  In recent years, management and the Board of Directors of Hologic have
discussed various business opportunities and strategic objectives, which
primarily focused on expanding Hologic's product lines. In the course of such
discussions, Hologic has considered possible alliances, combinations,
strategic investments and transactions with various participants in industries
compatible with Hologic's business.
 
  In early May 1996, management representatives of Hologic approached
representatives of FluoroScan to seek information regarding FluoroScan's
business. At the meeting, the parties exchanged general information regarding
their respective businesses and discussed in general terms potential product
distribution or technical collaboration. There were no discussions regarding a
possible business combination at this meeting.
 
  On June 4, 1996, Hologic senior management met to review their assessment of
FluoroScan and decided to invite FluoroScan management to visit Hologic for
further discussions.
 
                                      25

  On June 18, 1996, Messrs. Grossman and Issette, the Chief Executive Officer
and President of FluoroScan, respectively, met with Messrs. Ellenbogen, Muir
and Weinstein, the Chairman and Chief Executive Officer, Vice President of
Finance, and Vice President of New Business Development of Hologic,
respectively, at Hologic's Waltham, Massachusetts facility. At this meeting,
Hologic first mentioned its interest in a possible business combination with
FluoroScan, and the senior management teams of Hologic and FluoroScan began to
explore the feasibility of such a combination.
 
  On June 26, 1996, at a special meeting of the Hologic Board, Hologic's
management made an initial presentation on the considerations regarding, and
received questions and comments of the Hologic Board with respect to, a
possible business combination with FluoroScan. At this meeting, members of
Hologic management made a presentation consisting of descriptions of
FluoroScan's product lines, the results of preliminary due diligence through
the date of the meeting, and the possible risks and benefits of the proposed
combination. After consideration of management's presentation, the Hologic
Board concluded that management should pursue discussions with FluoroScan
regarding a possible strategic business combination.
 
  On June 28, 1996, Hologic formally engaged Needham & Company, Inc. to serve
as its financial advisor with regard to the potential business combination of
Hologic and FluoroScan.
 
  On July 1, 1996, Messrs. Grossman, Issette, Ellenbogen, Muir and Weinstein
met at an off-site location to discuss the possibility of a business
combination. At this time the parties discussed specific issues relating to
the combination including valuation, exchange ratio, representation of
FluoroScan management on the Hologic Board, and the continued employment of
FluoroScan executive officers. Upon the conclusion of this meeting, the
parties had reached a preliminary understanding on the general structure and
terms of a possible business combination.
 
  On July 3, 1996, management and legal, accounting and financial advisors of
Hologic, and management and legal and accounting advisors of FluoroScan met in
Chicago, Illinois to discuss the primary issues and terms of the potential
business combination of the two companies and to fix a timetable for the
proposed combination.
 
  From July 8 to July 10, 1996, management and legal, accounting and financial
advisors of Hologic and FluoroScan conducted their due diligence review of the
respective companies. During this time, representatives of the two companies
held a number of discussions regarding the terms of the proposed business
combination and the potential synergies and operational issues associated with
the proposed combination.
 
  On July 11, 1996, FluoroScan formally engaged the services of Rodman as its
financial advisor with regard to the proposed business combination.
 
  On July 16, 1996, at a special meeting of the Hologic Board called to review
the progress of the business combination negotiations and to consider the
approval of the Merger Agreement, a representative of Needham & Company, Inc.
made a presentation in which he reviewed certain strategic and financial
analyses of the proposed business combination. Outside legal counsel to
Hologic then reviewed with the Hologic Board its fiduciary duties in
considering the proposed combination and reviewed the principal terms of the
Merger Agreement and other documents related to the Merger. In addition,
management representatives of Hologic presented the Hologic Board with the
results of their due diligence review of FluoroScan and a summary of the
potential risks, synergies and benefits of the proposed combination. After
consideration of the various presentations, and discussion of the issues
raised in the course of such presentations, the Hologic Board unanimously
approved the Merger and the terms of the Merger Agreement and the other
related agreements, in substantially the form presented to the Hologic Board,
concluding that the Merger was fair to, and in the best interests of, Hologic.
 
  On July 16, 1996, as part of a special meeting of the FluoroScan Board
called to review the progress of the business combination negotiations and to
consider the approval of the Merger Agreement, a representative of Rodman made
a presentation in which he reviewed certain strategic and financial analyses
of the proposed business combination, and presented that firm's tentative oral
opinion that the conversion ratio to be paid to FluoroScan's stockholders in
the Merger, as then proposed, was fair, from a financial point of view, to
such
 
                                      26
<PAGE>
 
stockholders. Outside legal counsel to FluoroScan then reviewed with the Board
its fiduciary duties in considering the proposed combination and reviewed the
principal terms of the Merger Agreement and other documents related to the
Merger. In addition, management representatives of FluoroScan presented the
results of their due diligence review of Hologic and a summary of the
potential risks, synergies and benefits of the proposed combination. After
consideration of the various presentations, and discussion of the issues
raised in the course of such presentations, the FluoroScan Board unanimously
authorized the officers of FluoroScan to proceed with negotiations with
Hologic the next day, with the understanding that the FluoroScan Board would
reconvene prior to signing the Merger Agreement to further discuss the Merger
and further consider the opinion of Rodman as to whether the consideration to
be paid to FluoroScan stockholders in the Merger was fair, from a financial
point of view, to such stockholders.
 
  Negotiations between the management of Hologic and FluoroScan continued
throughout July 17 and July 18, 1996 both as to the terms of the Merger
Agreement, including the Conversion Ratio, termination rights and termination
fees, and nonsolicitation provisions, and as to the terms of certain
agreements related to the Merger Agreement. Final agreement on these and other
issues was reached over the course of several discussions between Messrs.
Grossman, Issette, Ellenbogen, Muir and Weinstein over this two day period.
 
  On July 18, 1996 at a special meeting of the Hologic Board called to review
the final terms of the Merger Agreement and the other related documents,
outside counsel to Hologic and a representative of Needham & Company, Inc.
reviewed with the Board the material changes to the terms of the Merger from
those presented at the July 16 meeting. Representatives of Hologic's
management also reviewed certain due diligence issues with the Board at this
meeting. The Board, after considering the revised terms of the Merger
Agreement, the other related documents, and the other issues discussed at the
meeting, again unanimously approved the Merger Agreement, the other related
agreements, and the Merger.
 
  On July 18, 1996 at a special meeting of the FluoroScan Board called to
review the final terms of the Merger Agreement and the other related documents
and to consider the approval of the Merger Agreement, management and outside
counsel to FluoroScan reviewed with the Board the material changes to the
terms of the Merger from those presented at the July 16 meeting. A
representative of Rodman presented that firm's oral opinion, confirmed in
writing later that day, that the Conversion Ratio was fair from a financial
point of view to such stockholders. The Board, after considering the revised
terms of the Merger Agreement and the other related documents and the various
presentations, unanimously approved the Merger and the terms of the Merger
Agreement and the other related agreements, in substantially the form
presented to the Board, concluding that the consideration to be paid to
FluoroScan's stockholders in the Merger was fair to and in the best interests
of FluoroScan and its stockholders.
 
  On the evening of July 18, 1996 Hologic, FluoroScan and Merger Sub executed
the Merger Agreement and certain related agreements.
 
HOLOGIC'S REASONS FOR THE MERGER
 
  The Board of Directors of Hologic has determined that the Merger is in the
best interests of Hologic and its stockholders, and therefore unanimously
approved the Merger.
 
  Hologic has been seeking to leverage its medical device development,
manufacturing and distribution expertise to expand, through acquisition or
strategic alliances, into complementary markets such as other diagnostic or
imaging markets. See "Information Relating to Hologic--Strategy." Hologic
believes that the business of FluoroScan meets this criteria for complementary
expansion and diversification. Among other things, the Hologic Board and
management considered the following factors: (i) FluoroScan products are based
on X-ray technology, an area of Hologic technical expertise; (ii) FluoroScan
products address a market, minimally invasive orthopedic surgery, that Hologic
believes offers attractive future growth potential; (iii) FluoroScan has
established an effective sales channel in the United States to address its
market which Hologic believes will be complimentary to Hologic's existing
domestic sales channels; (iv) Hologic believes that its well established
international sales and marketing structure could be used to accelerate the
expansion of the sale of FluoroScan's products in international markets; (v)
Hologic believes that its greater resources, including research and
 
                                      27
<PAGE>
 
development personnel and working capital, should be able to further assist
FluoroScan in maintaining and enhancing its market position; and
(vi) FluoroScan's size was in the appropriate range for effective integration
with Hologic. Hologic's Board and management believed that a combination of
the foregoing factors, among others, should enhance stockholder value of
Hologic in the future, but Hologic's Board of Directors did not assign greater
relative weight to any one of these factors.
 
  In approving the Merger Agreement, as part of the due diligence process, the
Hologic Board considered the information about FluoroScan available to it from
FluoroScan management and interviews with FluoroScan customers, an assessment
of FluoroScan's technology, resources, distribution network, and financial
condition, and information contained in FluoroScan's filings with the
Commission. In doing so, the Hologic Board not only considered the benefits
that could arise from the Merger, but also considered certain adverse effects
relating to the Merger, including the dilution to Hologic stockholders
resulting from the issuance of the shares of Hologic Common Stock pursuant to
the Merger, certain nonrecurring costs that would result from the Merger, and
the risks inherent in any merger, including the risk that the businesses of
Hologic and FluoroScan will not be able to be successfully integrated, and
other risks and uncertainties relating to the businesses of Hologic and
FluoroScan, including without limitation those described herein under "Risk
Factors."
 
FLUOROSCAN'S REASONS FOR THE MERGER
 
  In its evaluation of the Merger, FluoroScan's Board of Directors considered
a number of factors prior to approving the Merger, including the following:
 
  .  The Merger would provide FluoroScan's stockholders with shares of
     Hologic Common Stock in a tax-free exchange at a substantial premium
     over the current market price for FluoroScan Common Stock.
 
  .  The Merger would enable FluoroScan's stockholders to own shares in
     Hologic, which is a company with access to broader markets and
     distribution channels than those of FluoroScan; and, at the same time,
     would provide FluoroScan's stockholders the opportunity to continue to
     participate in the long term growth and appreciation of both Hologic and
     FluoroScan.
 
  .  The Merger would provide the opportunity to increase revenues by
     combining the customer bases and complementary product offerings of both
     companies.
 
  .  The Merger would provide the potential to expand the market presence of
     FluoroScan worldwide through Hologic's sales force and distribution
     networks.
 
  .  The Merger would provide FluoroScan's stockholders with greater
     liquidity in their investment than they have had with their FluoroScan
     shares because of the larger trading volume of Hologic's Common Stock.
 
  .  Information with respect to the financial condition and business of
     Hologic, including among other things, Hologic's recent and historical
     stock and earnings performance, the demonstrated ability of Hologic to
     successfully implement its growth strategy, and the ability of Hologic
     to access the capital markets and its stated commitment to expanding
     FluoroScan's business.
 
  .  The terms of the Merger Agreement offer FluoroScan's stockholders
     certain protection including an increase in the Conversion Ratio if the
     price of Hologic Common Stock falls below a certain threshold level or,
     in the event Hologic does not agree to increase the Conversion Ratio
     should the price of Hologic Common Stock fall below such a level,
     providing FluoroScan the right to terminate the Merger Agreement and the
     Merger. See "The Merger and Related Transactions--Background of the
     Merger" and "--Termination."
 
  .  The opinion of Rodman to FluoroScan's Board that, as of July 18, 1996,
     the Conversion Ratio was fair, from a financial point of view, to
     FluoroScan's stockholders. See "The Merger and Related Transactions--
     Opinion of FluoroScan's Financial Advisor."
 
  In the course of its deliberations, the Board of Directors of FluoroScan
reviewed a number of additional factors relevant to the Merger, including
principally (i) the capital structure of Hologic; (ii) premiums to market and
multiples paid in other merger and acquisition transactions of this nature;
(iii) an analysis of the relative
 
                                      28
<PAGE>
 
value that FluoroScan might contribute to the future business and prospects of
the combined company; (iv) the compatibility of the management and businesses
of Hologic and FluoroScan; (v) the financial presentation by Rodman; and (vi)
reports from management and legal advisors on specific terms of the Merger
Agreement and the other agreements to be entered into in connection with the
Merger Agreement and other matters. For a discussion of many of the foregoing
factors, see "The Merger and Related Transactions--Opinion of FluoroScan
Financial Advisor" below.
 
  The Board of Directors of FluoroScan also considered a number of potentially
negative factors in its deliberations concerning the Merger, including, among
other things: (i) the possibility of management disruption associated with the
Merger and the risk that, despite the efforts of the combined company, key
management personnel of FluoroScan might not continue with the combined
company; (ii) the risk that the benefits sought to be achieved by the Merger,
such as operating leverage and access to an established foreign distribution
network, will not be achieved; (iii) the fact that Hologic Common Stock was
trading at a relatively high multiple of earnings; (iv) the downward
adjustment to the Conversion Ratio if the Average Market Value exceeds $50.29;
(v) the loss of independence which would result from being a wholly-owned
subsidiary of Hologic; and (vi) the risks of the medical device industry in
general and Hologic in particular such as those described elsewhere in this
Proxy Statement/Prospectus. See "Risk Factors."
 
  The foregoing discussion of the information and factors considered by
FluoroScan's Board of Directors is not intended to be exhaustive but is
believed to include all material factors considered by the FluoroScan Board.
In view of the wide variety of factors, both positive and negative, considered
by FluoroScan's Board of Directors, the Board did not find it practical to,
and did not, quantify or otherwise assign relative weights to the specific
factors considered and individual directors may have given differing weights
to different factors.
 
  After taking into consideration all of the factors set forth above, together
with an analysis of the presentations of management, Rodman, and legal
counsel, the Board of Directors of FluoroScan unanimously determined that the
Merger was fair to and in the best interests of FluoroScan and its
stockholders and that FluoroScan should proceed with the Merger at this time.
 
OPINION OF FLUOROSCAN'S FINANCIAL ADVISOR
 
  At the special meeting of FluoroScan's Board of Directors on July 18, 1996,
Rodman rendered its written opinion that, as of such date, based upon and
subject to the various considerations set forth in the opinion, the Conversion
Ratio is fair to the holders of FluoroScan Common Stock. Rodman's opinion
addresses only the fairness of the Conversion Ratio from a financial point of
view to the holders of FluoroScan Common Stock and does not constitute a
recommendation to any stockholder of FluoroScan as to how such stockholder
should vote at the Special Meeting. The full text of the opinion of Rodman,
which sets forth the assumptions made, procedures followed, matters considered
and limits of its review, is attached hereto as Appendix B and is incorporated
herein by reference. Stockholders of FluoroScan Common Stock are urged to read
such opinion in its entirety.
 
  In arriving at the opinion dated July 18, 1996, Rodman has, among other
things, with respect to FluoroScan: (i) reviewed, from a financial point of
view, the Merger Agreement and annexes thereto; (ii) reviewed the Annual
Reports to Stockholders and Annual Reports on Form 10-KSB of FluoroScan for
the years ended December 31, 1994 and 1995 and its interim reports on Form 10-
QSB and 8-K filed since July 11, 1994; (iii) reviewed certain publicly
available financial and operating data relating to the business and prospects
of FluoroScan, which historical information and data the management of
FluoroScan represented to Rodman as fairly presenting the financial condition
and operating results of FluoroScan as of the dates presented and, with
respect to the prospects of FluoroScan, as being reasonable evaluations of
FluoroScan's prospects; (iv) discussed certain financial information and the
business and prospects of FluoroScan with its senior management; (v) reviewed
the reported historical and recent market prices and trading volumes of
FluoroScan's Common Stock; (vi) compared the financial, operating and stock
price performance of FluoroScan with certain other publicly held companies
deemed comparable; (vii) reviewed the financial terms, to the extent publicly
available, of certain
 
                                      29
<PAGE>
 
other acquisition transactions deemed comparable; and (viii) made such other
analyses and examinations as Rodman deemed necessary or appropriate. Rodman
has, among other things, with respect to Hologic: (i) studied the Annual
Reports to Stockholders and Annual Reports on Form 10-K of Hologic for the
years ended September 25, 1993, September 24, 1994 and September 30, 1995 and
its interim reports on Form 10-Q and 8-K filed since September 25, 1993; (ii)
reviewed certain publicly available financial and operating data relating to
the business and prospects of Hologic, which historical information and data
the management of Hologic represented to Rodman as fairly presenting the
financial condition and results of operations of Hologic as of the dates
presented and, with respect to the prospects of Hologic, as being reasonable
evaluations of Hologic's prospects; (iii) discussed certain financial
information and the business and prospects of Hologic with its senior
management; (iv) reviewed the reported historical and recent market prices and
trading volumes of Hologic's Common Stock; (v) compared the financial,
operating and stock price performance of Hologic with certain other publicly
held companies deemed comparable; (vi) reviewed the financial terms, to the
extent publicly available, of certain other acquisition transactions deemed
comparable; and (vii) made such other analyses and examinations as Rodman
deemed necessary or appropriate.
 
  Rodman relied upon the accuracy and completeness of all information supplied
or otherwise made available to it by FluoroScan and Hologic or obtained by it
from other sources, and relied upon the representations of respective
management of FluoroScan and Hologic that they are unaware of any information
or facts that would make the information provided incomplete or misleading.
Rodman has not independently verified such information, undertaken an
independent appraisal of the assets or liabilities (contingent or otherwise)
of FluoroScan or Hologic, nor has it been furnished with any such appraisals.
With respect to the publicly available financial forecasts with regard to each
of FluoroScan and Hologic which Rodman reviewed, it relied on the
representations of respective management of FluoroScan and Hologic that such
available forecasts were reasonable and that: (i) as to the respective
forecasts, they were not aware of any facts that would make such information
incomplete, in any material respect, or misleading; and (ii) there had been no
material adverse developments in the business (financial or otherwise) or
prospects of FluoroScan or Hologic, since each company's most recent fiscal
year end. Rodman assumed, on the basis of advice from FluoroScan's independent
public accountants and counsel, that the Merger will be treated as a pooling
of interests in accordance with generally accepted accounting principles and
as a tax free reorganization for Federal income tax purposes. While Rodman
believes that its review, as described herein, is an adequate basis for the
opinion it has expressed, its opinion is necessarily based upon market,
economic and other conditions that existed and could be evaluated as of the
date of its opinion and any change in such conditions would require a re-
evaluation of its opinion.
 
  In the performance of its financial advisory services, Rodman was not
authorized to solicit, and did not solicit, interest from any party with
respect to the acquisition of FluoroScan or any of its assets. No other
limitations were imposed upon Rodman by FluoroScan with respect to the
investigations to be made or procedures to be followed by it in rendering its
opinion.
 
  Comparative Stock Price Performance. As part of its analysis, Rodman
reviewed the recent stock market performance of FluoroScan and Hologic and
compared such performance to a group of diagnostic device companies, including
Alliance Imaging, Fischer Imaging and OEC Medical Systems (the "Diagnostic
Device Companies") and a group of osteoporosis companies, including Lunar and
Norland Medical Systems. Rodman observed that over the period from January 6,
1995 through July 12, 1996, FluoroScan underperformed its peer group and the
S&P 500 and Hologic outperformed its peer group and the S&P 500.
 
  Comparable Company Analysis. Rodman reviewed selected actual and estimated
financial, operating and stock market information for FluoroScan and compared
that information with corresponding information for comparable Diagnostic
Device Companies.
 
  Rodman compared the total enterprise value (equity value at market, plus
total long-term debt, less cash and cash equivalents) of the Diagnostic Device
Companies to revenues, income before interest and taxes ("EBIT") and income
before interest, taxes, depreciation and amortization ("EBITDA") for the
latest 12
 
                                      30
<PAGE>
 
months as reported by each company to the Commission, and the stock prices of
the Diagnostic Device Companies to the Diagnostic Device Companies' reported
earnings per share for the latest 12 months and projected earnings per share
for the 12 months ending December 31, 1996 and December 31, 1997 (where
available).
 
  Such analysis indicated that for the Diagnostic Device Companies the range
of multiples were as follows: (i) for revenue, the range of multiples was 1.0
to 2.3 with a Diagnostic Device Company average of 1.5; (ii) for EBIT, the
range of multiples was 12.7 to 17.9 with a Diagnostic Device Company average
of 14.5; (iii) for EBITDA, the range of multiples was 5.5 to 11.7 with a
Diagnostic Device Company average of 9.0; and (iv) for market capitalization
(equity value at market) in terms of a multiple of net income, the range of
multiples was 12.8 to 20.2 with a Diagnostic Device Company average of 15.6.
 
  By comparison, the multiples for FluoroScan were 1.6 times its revenues,
11.2 times its EBIT, 10.5 times its EBITDA and 18.0 times its market
capitalization/net income.
 
  Comparable Transaction Analysis. Rodman reviewed certain publicly available
information relating to three completed merger and acquisition transactions
deemed comparable. The comparable transactions involved the combination of:
(i) Osteo Sciences with Metra Biosystems; (ii) Orthomet with Wright Medical
Technology; and (iii) BioSurface Technology with Genzyme. Rodman reviewed the
consideration paid in such transactions in terms of price paid for the common
stock ("Equity Value"), plus total debt, less cash and cash equivalents
("Total Consideration"), as a multiple of latest 12 months revenues, EBIT and
EBITDA, and Equity Value as a multiple of net income. The average of these
multiples was 2.0 times, 19.4 times, 12.1 times and 24.6 times, respectively.
Based on the conversion ratio for FluoroScan Common Stock under the Merger
Agreement, as of July 18, 1996, Total Consideration to holders of FluoroScan
Common Stock from the Merger represents multiples of 3.3 times latest 12 month
revenues of FluoroScan, 23.3 times latest 12 month EBIT of FluoroScan, 22.0
times latest 12 month EBITDA of FluoroScan and Equity Value to latest 12 month
net income of 44.6 times.
 
  Discounted Cash Flow Analysis. Rodman conducted a discounted cash flow
analysis for the years ending December 31, 1996 to 2000 for the purpose of
valuing the outstanding shares of FluoroScan Common Stock. It computed the
terminal value of FluoroScan using projected EBITDA for the year ending
December 31, 2000 multiplied by a range of EBITDA multiples, which varied from
10.0 to 20.0 times. The terminal value of the business, as well as cash flows
for the preceding years, were then discounted five years at a range of
discount rates from 10.0% to 15.0%. This analysis indicated a range of values
per share of FluoroScan Common Stock of $7.17 to $10.65, compared to an actual
price on July 17, 1996 of $8.00.
 
  Rodman's summary and further analysis showed that the "Comparable Company
Analysis" implied a valuation per share that ranges from $6.94 to $9.91 with
an average of $7.97, the "Comparable Transaction Analysis" implied a valuation
per share that ranged from $8.90 to $13.09 with an average of $10.97, the
"Discounted Cash Flow Analysis" implied a valuation per share that ranged from
$7.17 to $10.65 with an average of $8.79. The average of all valuation methods
implied a valuation per share of FluoroScan Common Stock of $9.25. As of the
date of Rodman's opinion the Conversion Ratio offered by Hologic for each
FluoroScan Common Share exceeded the minimum value for FluoroScan determined
under each valuation method and the average value for FluoroScan Common Stock
determined under all of these valuation methods.
 
  The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analysis or summary description. Selecting
portions of the analyses or of the summary set forth above, without
considering the analysis as a whole, could create an incomplete view of the
processes underlying Rodman's opinion. In arriving at its fairness
determination, Rodman considered the results of all such analyses. No company
or transaction used in the above analysis as a comparison is identical to
FluoroScan or Hologic or the proposed Merger, accordingly, an analysis of the
results of the foregoing is not purely quantitative. Rather, it involves
complex considerations and judgments concerning the differences in operating
and financial characteristics of the companies and other factors that could
affect the public trading values of the companies or company to which they are
compared.

  The analyses were prepared solely for purposes of enabling Rodman to provide
its opinion as to the fairness to holders of FluoroScan Common Stock of the
Conversion Ratio pursuant to the Merger Agreement and do not purport to be
appraisals or necessarily reflect the prices at which businesses or securities
actually may be sold. Analyses based upon forecasts of future results are not
necessarily indicative of actual future results which may be significantly
more or less favorable than suggested by such analyses. The FluoroScan Board
retained Rodman to act as its financial advisor in connection with the
consideration by FluoroScan of the Merger, and to provide an opinion as to the
fairness, from a financial point of view, of the consideration to be received
by the holders of FluoroScan Common Stock in such transaction. As described
above, Rodman's opinion and presentation to the FluoroScan Board was one of
several factors taken into consideration by the FluoroScan Board in making its
determination to approve the Merger. The foregoing summary does not purport to
be a complete description of the analyses performed by Rodman and is qualified
by reference to the written opinion of Rodman set forth in Appendix B hereto.
 
SELECTION AND COMPENSATION OF FLUOROSCAN'S FINANCIAL ADVISOR
 
  Rodman is a nationally recognized investment banking firm and, as part of
its investment banking activities, is regularly engaged in the valuations of
businesses and their securities in connection with mergers and acquisitions,
negotiated under writing secondary distributions of listed and unlisted
securities, private placements and valuations for corporate and other
purposes. Rodman has never been involved in any prior transaction with either
FluoroScan or Hologic. Rodman was retained to provide a fairness opinion in
its capacity as an independent financial advisor. Pursuant to a letter
agreement dated July 11, 1996 and amended July 17, 1996, FluoroScan agreed to
pay Rodman a fee of $200,000, payable in cash as follows: (i) $50,000 upon
execution of the engagement letter; (ii) $100,000 upon rendering a fairness
opinion; and (iii) $50,000 at the Effective Time. FluoroScan also agreed to
reimburse Rodman for expenses not to exceed $20,000, including fees and
expenses of its legal counsel incurred by it and to indemnify Rodman for
certain liabilities that may arise out of the rendering of its services or
opinions.
 
RECOMMENDATION OF FLUOROSCAN BOARD OF DIRECTORS
 
  THE BOARD OF DIRECTORS OF FLUOROSCAN HAS DETERMINED THAT THE MERGER IS FAIR
TO AND IN THE BEST INTERESTS OF FLUOROSCAN AND ITS STOCKHOLDERS AND HAS
UNANIMOUSLY RECOMMENDED A VOTE FOR APPROVAL AND ADOPTION OF THE MERGER
AGREEMENT AND THE MERGER.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
  In considering the recommendation of the FluoroScan Board of Directors with
respect to the Merger, stockholders of FluoroScan should be aware that certain
members of FluoroScan's management and the FluoroScan Board of Directors have
interests in the Merger that are in addition to the interests of the
stockholders of FluoroScan generally. The FluoroScan Board of Directors was
aware of these interests and considered them, among other matters, in
approving the Merger Agreement and the Merger.
 
  Stock Options. Pursuant to the Merger Agreement, at the Effective Time, each
FluoroScan Plan Option then outstanding under the FluoroScan Option Plans,
whether vested or unvested, shall be assumed by Hologic as described under
"The Merger and Related Transactions--General" above. In addition, the
outstanding Director Options to purchase, in the aggregate, 72,000 shares of
FluoroScan Common Stock will entitle the holders to receive cash payments
equal to the fair market value of such shares minus their exercise price
following the Merger. Assuming a fair market value of $12.50 per share of
FluoroScan Common Stock, these directors would receive an aggregate of
approximately $400,000 if they exercised their right to receive cash payments
for all of their outstanding options. Each of the holders of Director Options
has agreed to waive his right to such payment and have his Director Options
assumed by Hologic in the event that such cash payments would cause the Merger
not to qualify as a pooling of interest for accounting and financial reporting
purposes. As of the Record Date Larry S. Grossman, Arlen L. Issette and all
current officers as a group held options to
 
                                      32
<PAGE>
 
purchase 300,000, 300,000 and 735,000 shares, respectively, of FluoroScan
Common Stock under the FluoroScan Option Plans at exercise prices ranging from
$6.19 to $7.15 per share, and the independent FluoroScan Directors held
options to purchase 72,000 shares of FluoroScan Common Stock at exercise
prices ranging from $6.19 to $9.63 per share. In addition, one director holds
FluoroScan Unit Options to purchase FluoroScan Units at an exercise price of
$10.50 per FluoroScan Unit.
 
  Employment Arrangements with Certain FluoroScan Officers. Simultaneously
with the execution of the Merger Agreement, each of Larry S. Grossman and
Arlen L. Issette, the Chief Executive Officer and President of FluoroScan,
respectively, entered into an Amended and Restated Employment Agreement
("Employment Agreement") with FluoroScan and Hologic that will become
effective and supersede their current employment agreements (the "Current
Employment Agreements")with FluoroScan upon consummation of the Merger. The
Employment Agreements provide for the continuation of Messrs. Grossman's and
Issette's employment with FluoroScan on terms substantially equivalent to
their respective Current Employment Agreements.
 
  The Employment Agreements provide that Messrs. Grossman and Issette will
continue as Chief Executive Officer and President of FluoroScan, respectively,
continue as directors of FluoroScan and become Vice Presidents of Hologic, and
that Mr. Grossman will become a director of Hologic upon the consummation of
the Merger. The Employment Agreements continue through the term of the Current
Employment Agreements, February 15, 1999. During the term of the Employment
Agreements, Messrs. Grossman and Issette will receive their current salary of
$220,000 per year, subject to a 5% increase in each year commencing on
February 15, 1997, will be entitled to a discretionary bonus as determined by
the Board of Directors of Hologic or FluoroScan, and participate in Hologic's
fringe benefit plans on the same terms as other Hologic executive officers.
The Employment Agreements also provide for the continuation of $2,000,000 of
split dollar life insurance policies, with a cost of $28,000 per year, for the
benefit of members of Messrs. Grossman's and Issette's respective families and
the right of each of Messrs. Grossman and Issette to buy-out the policies for
their cash value upon termination of his Employment Agreement.
 
  The Employment Agreements contain other terms similar to those contained in
the Current Employment Agreements, including (i) the right of Hologic and
FluoroScan to terminate Messrs. Grossman or Issette for cause, (ii) the right
of Messrs. Grossman or Issette to terminate his services, while continuing to
be paid under his Employment Agreement for the remainder of the term, if he is
required to relocate outside of the Chicago Metropolitan Area, upon certain
changes of his responsibilities, or upon certain changes of control of
FluoroScan or Hologic, (iii) proprietary information and confidentiality
agreements, and (iv) the agreement of each of Messrs. Grossman and Issette not
to compete with Hologic or FluoroScan for a period of two years following his
termination of employment (including any period in which he is paid a salary,
whether or not employed).
 
  Continuing Rights to Indemnification; Limitation of Liability; Directors'
and Officers' Liability Insurance. The Merger Agreement provides that for a
period of five years after the Effective Time, Hologic will cause FluoroScan
to maintain in effect the current policies of directors' and officers'
liability insurance maintained by FluoroScan (or policies of at least the same
coverage and amounts containing terms and conditions which are no less
advantageous) with respect to claims arising from facts or events which
occurred before the Effective Time; provided, however, that FluoroScan will
not be obligated to make annual premium payments for such insurance to the
extent that such premiums exceed an amount equal to 150% of the annual
premiums paid as of the date of the Merger Agreement by FluoroScan for such
insurance and, if such premiums exceed such amount, FluoroScan will only be
required to purchase insurance policies in amounts and with coverage as
reasonably can be purchased for such amount.
 
  The Merger Agreement further provides that Hologic will assume joint
liability with FluoroScan for its indemnification obligations to FluoroScan's
directors, in all capacities in which such directors served FluoroScan or its
subsidiaries while directors prior to the Effective Time, as set forth in
FluoroScan's Amended and Restated Certificate of Incorporation, provided that
Hologic's maximum obligation under this agreement will be limited to the
working capital of FluoroScan as of the Effective Time less any amounts
indemnified by FluoroScan
 
                                      33
<PAGE>
 
(excluding amounts paid by insurance of FluoroScan). FluoroScan's Amended and
Restated Certificate of Incorporation provides that FluoroScan's directors
will be indemnified to the full extent permitted by Delaware Law.
 
  The Merger Agreement further provides that Hologic will assume joint
liability with FluoroScan for any indemnification obligation it may have to
directors of FluoroScan who continue to serve as directors of FluoroScan after
the Effective Time pursuant to any indemnification agreements entered into by
FluoroScan with such directors, with respect to acts or events (in any
capacity) while serving as a director of FluoroScan on or after the Effective
Time. Pursuant to their Employment Agreements, Messrs. Issette and Grossman
will continue to serve as directors of FluoroScan following the consummation
of the Merger and thereby continue to be entitled to such indemnification. In
addition, under Mr. Grossman's Employment Agreement, Hologic has also agreed
to enter into an indemnification agreement with Mr. Grossman on the same terms
as Hologic's indemnification agreements with its current directors.
 
MATERIAL CONTACTS BETWEEN HOLOGIC AND FLUOROSCAN
 
  Other than the discussions in May, June and July 1996 between Hologic and
FluoroScan concerning the feasibility of a strategic relationship between
Hologic and FluoroScan and the negotiations relating to, and entry into, the
Merger Agreement discussed in "The Merger and Related Transactions--Background
of the Merger," the Stockholder Option Agreement between Hologic and certain
Stockholders of FluoroScan discussed under "The Merger and Related
Transactions--Option Agreement with Certain Stockholders" and the Stockholder
Agreements between Hologic and certain stockholders of FluoroScan discussed
under "The Special Meeting--Intentions and Agreements to Vote," Hologic and
FluoroScan do not know of any past, present or proposed material contracts,
arrangements, understandings, relationships, negotiations or transactions
between FluoroScan or its affiliates and Hologic or its affiliates.
 
REPRESENTATIONS, WARRANTIES AND COVENANTS
 
  Hologic and FluoroScan have made certain representations and warranties to
each other relating to, among other things, organization, capitalization and
share ownership, authorization for, and absence of conflicts resulting from,
the Merger, compliance with laws, the accuracy and completeness of financial
statements and certain filings with the Commission, financial condition,
employment benefit plans, legal actions and proceedings and, in the case of
FluoroScan, intellectual property, tax matters, contracts, insurance, product
warranty, inventories, environmental matters, properties, employees,
customers, suppliers, and financial condition.
 
  Hologic and FluoroScan have agreed: (i) to use their respective commercially
reasonable efforts to consummate the transactions contemplated by the Merger
Agreement; (ii) to obtain all waivers, permits, consents, approvals or other
authorizations from third parties and governmental entities necessary for the
consummation of the transactions contemplated by the Merger Agreement; (iii)
to jointly prepare and file with the Commission under the Exchange Act proxy
materials for the purpose of soliciting proxies from FluoroScan stockholders
to vote in favor of the approval of the Merger Agreement at the Special
Meeting; (iv) to promptly notify the other party in writing of the occurrence
of any event or development that would (a) render any statement,
representation or warranty of either party in the Merger Agreement inaccurate
or incomplete in any material respect or (b) constitute or result in a breach
by either party or failure by either party to comply with, any agreement or
covenant in the Merger Agreement applicable to such party; (v) to promptly
advise and cooperate with the other party prior to a party's issuance of any
press release or other information to the press or to any third party with
respect to the Merger Agreement or the transactions contemplated thereby; and
(vi) to keep confidential and not use in any manner any information or
documents obtained from the other party, except as provided in the Merger
Agreement.
 
  FluoroScan has also agreed: (i) to permit representatives of Hologic to have
full access to all premises, properties, financial and accounting records,
contracts, other records, documents and personnel, of or pertaining to
FluoroScan; (ii) to obtain from its affiliates the agreements referred to
under "The Merger and Related
 
                                      34

Transactions--Accounting Treatment;" and (iii) to encourage the employees of
FluoroScan to remain in the employ of FluoroScan following the Effective Time
 .
 
CONDUCT OF BUSINESS OF FLUOROSCAN PENDING THE MERGER
 
  FluoroScan has agreed in the Merger Agreement that prior to the consummation
of the Merger, it will, among other things, conduct its operations in the
ordinary course of business and in compliance with all applicable laws and
regulations and, to the extent consistent therewith, use all reasonable
efforts to preserve intact its current business organization, keep its
physical assets in good working condition, keep available the services of its
current officers and employees and preserve its relationships with customers,
suppliers and others having business dealings with it to the end that its
goodwill and ongoing business shall not be impaired in any material respect.
 
  FluoroScan has also agreed that prior to the consummation of the Merger it
will not, without the prior written consent of Hologic, take certain actions
including without limitation: (i) the issuance, sale or delivery of
securities, or the commitment or authorization therefor; (ii) the split,
recombination or reclassification of shares of capital stock or the payment of
any dividend; (iii) the creation or assumption of debt (except in the ordinary
course of business) or the making of any loans; (iv) the adoption or amendment
of any employee benefit plan or employment or severance arrangement; (v) the
acquisition, sale or transfer of any equity interests in any entity (except in
the ordinary course of business); (vi) any amendment of FluoroScan charter
documents; (vii) any changes in any material respect in accounting methods;
(viii) the discharge or satisfaction of security interests; (ix) the mortgage
or pledge of any property or assets; (x) the transfer of any intellectual
property (except in the ordinary course of business); (xi) the taking of any
action that would result in a violation or default under any material
contract; (xii) the making or commitment to make any capital expenditure in
excess of specified dollar amounts; (xiii) the taking of any action that would
result in a breach of any representation or warranty in the Merger Agreement
or would result in any of the conditions to the Merger not being satisfied; or
(xiv) the taking of any action that would jeopardize the treatment of the
Merger as a "pooling of interests."
 
NO SOLICITATION
 
  The Merger Agreement provides that subject to certain exceptions described
below, FluoroScan will not, and will not permit its officers, directors,
employees, representatives and agents, directly or indirectly: (i) to
encourage, solicit, initiate, engage or participate in discussions or
negotiations with any person or entity (other than Hologic) concerning any
merger, consolidation, sale of material assets, tender offer,
recapitalization, accumulation of shares of FluoroScan Common Stock, proxy
solicitation or other business combination involving FluoroScan or any
subsidiary or division of FluoroScan (an "Acquisition Transaction"); or (ii)
to provide any information concerning the business, properties or assets of
FluoroScan to any person or entity (other than Hologic). Nonetheless, if
FluoroScan receives an unsolicited written proposal for, or an unsolicited
written indication of a serious interest in entering into, an Acquisition
Transaction from a bona fide, financially capable third party that contains no
financing contingency, (i) FluoroScan in its discretion may furnish to and
communicate with such third party public information requested by such party,
and (ii) FluoroScan may enter into discussions and negotiations with such
third party and may, at the request of such third party, furnish such third
party with non-public information concerning FluoroScan, provided (in the case
of this clause (ii)) that (a) FluoroScan gives Hologic written notice thereof
at least five business days prior to furnishing any such information, (b)
FluoroScan's Board of Directors, after consultation with and based upon the
advice of an independent financial advisor (who may be FluoroScan's regularly
engaged financial advisor), determines in good faith that such third party is
financially capable, without any financing contingency, of consummating an
Acquisition Transaction that would yield a higher value to FluoroScan
stockholders than will the Merger, (c) FluoroScan's Board of Directors, after
weighing such advice, determines that taking such action is more likely than
not to lead to an Acquisition Transaction with such third party that would
yield a higher value to FluoroScan stockholders than will the Merger, and (d)
the Company's Board of Directors shall have been advised in writing by
independent legal counsel (who may be the Company's regular legal counsel),
that any failure to provide such non-public information to such party would
likely constitute a breach of the fiduciary responsibilities of the Board of
Directors to FluoroScan's stockholders.
 
                                      35

receipt of any inquiries or proposals relating to an Acquisition Transaction
and any actions taken pursuant to the preceding paragraph.

EFFECTIVE TIME
 
  The Effective Time of the Merger will occur upon the filing of a Certificate
of Merger with the Secretary of State of the State of Delaware or at such
later time as is specified on such certificate. The filing of the Certificate
of Merger will occur as soon as practicable after the satisfaction of the
conditions set forth in the Merger Agreement, which is currently expected to
be on or about August 29, 1996. The Merger Agreement may be terminated by
either party if the Merger has not been consummated on or before November 30,
1996 and under certain other conditions. See "The Merger and Related
Transactions--Conditions to the Merger," "--Termination" and "--Termination
Fees and Expenses."
 
TERMINATION
 
  The party or parties identified below may terminate the Merger Agreement
prior to the Effective Time (whether before or after stockholder approval is
obtained) with the prior authorization of its or their respective Boards of
Directors, as the case may be, as follows:
 
    (i) Hologic and FluoroScan may terminate the Merger Agreement by mutual
  consent;

  (a) without fault of such terminating party, the Merger shall not have been
  consummated on or before November 30, 1996, (b) any court of competent
  jurisdiction in the United States or other governmental body in the United
  States shall have issued an order (other than a temporary restraining
  order), decree or ruling or taken any other action
 
                                      37
<PAGE>
 
  restraining, enjoining or otherwise prohibiting the Merger, and such order,
  decree ruling or other action shall have become final and nonappealable, or
  (c) FluoroScan stockholders fail to approve the Merger Agreement and the
  Merger at the Special Meeting;
 
    (iii) Hologic may terminate the Merger Agreement if (a) FluoroScan shall
  have failed to comply in any material respect with any of the covenants or
  agreements contained in the Merger Agreement to be complied with or
  performed by FluoroScan at or prior to such date of termination; provided,
  however, that if such failure or failures are capable of being cured prior
  to the Effective Time, such failure, or failures shall not have been cured
  within 15 days of delivery to FluoroScan of written notice of such failure
  or failures, (b) there exists a breach or breaches of any representation or
  warranty of FluoroScan contained in the Merger Agreement in any material
  respect such that a Hologic closing condition would not be satisfied;
  provided, however, that if such failure, breach or breaches are capable of
  being cured prior to the Effective Time, such failure, breach or breaches
  shall not have been cured within 15 days of delivery to FluoroScan of
  written notice of such failure, breach or breaches, or (c) FluoroScan shall
  furnish or disclose non-public information to a third party with respect to
  any Acquisition Transaction, or shall have resolved to do the foregoing and
  publicly disclose such resolution; and
 
    (iv) FluoroScan may terminate the Merger Agreement if (a) Hologic or
  Merger Sub shall have failed to comply in any material respect with any of
  the covenants or agreements contained in the Merger Agreement to be
  complied with or performed by Hologic or Merger Sub at or prior to such
  date of termination; provided, however, that if such failure or failures
  are capable of being cured prior to the Effective Time, such failure or
  failures shall not have been cured within 15 days of delivery to Hologic of
  written notice of such failure or failures, (b) there exists a breach or
  breaches of any representation or warranty of Hologic or Merger Sub
  contained in the Merger Agreement in any material respect such that a
  FluoroScan closing condition would not be satisfied; provided, however,
  that if such failure, breach or breaches are capable of being cured prior
  to the Effective Time, such failure, breach or breaches shall not be cured
  within 15 days of delivery to Hologic of written notice of such failure,
  breach or breaches; or (c) if the Average Market Value of the Hologic
  Common Stock is less than $30.17 and Hologic does not elect to adjust the
  conversion ratio to equal $9.37 divided by the Average Market Price within
  15 days after the date of the Special Meeting.
 
TERMINATION FEE AND EXPENSES
 
  In the event of a termination of the Merger Agreement (i) because FluoroScan
stockholders fail to approve the Merger Agreement and the Merger at the
Special Meeting or (ii) by Hologic as a result of a breach by FluoroScan of
the Merger Agreement or FluoroScan furnishing or disclosing non-public
information to a third party with respect to any potential Acquisition
Transaction, or resolving to do the foregoing and publicly disclosing such
resolution, then FluoroScan shall pay Hologic up to $1.5 million for all
documented fees and expenses incurred by Hologic (including the reasonable
fees and expenses of counsel, accountants, consultants and advisors) in
connection with the Merger Agreement and the transactions contemplated thereby
(the "Hologic Documented Expenses").
 
  In the event of a termination of the Merger Agreement (i) because FluoroScan
stockholders fail to approve the Merger Agreement and the Merger at the
Special Meeting, where the Board of Directors of FluoroScan withdraws its
recommendation of the Merger or modifies such recommendation in a manner
adverse to Hologic, or (ii) as a result of FluoroScan disclosing non-public
information to a third party with respect to any potential Acquisition
Transaction, or resolving to do the foregoing and publicly disclosing such
resolution, FluoroScan shall promptly pay Hologic an additional fee of $2.4
million (the "Termination Fee"). To the extent that either Hologic Documented
Expenses or the Termination Fee have not already become payable and been paid,
and, if prior to any termination of the Merger Agreement (other than a
termination of the Merger Agreement by FluoroScan as a result of any breaches
of the Merger Agreement by Hologic or Hologic's election not to adjust the
Conversion Ratio if the Average Market Value is below $30.17), any person
shall have made a bona fide proposal concerning a Business Combination
Transaction (as defined below) and prior to or within twelve months after the
termination of the Merger Agreement, FluoroScan or any of its subsidiaries, or
any affiliate of
 
                                      38
<PAGE>
 
FluoroScan, enters into a definitive agreement with a third party with respect
to a Business Combination Transaction or a Business Combination Transaction is
effected, then FluoroScan, prior to entering into any such definitive
agreement or effecting any such Business Combination Transaction, shall
promptly pay Hologic the Hologic Documented Expenses and the Termination Fee.
For purposes of the foregoing, the term "Business Combination Transaction"
means any of the following involving FluoroScan or any of its subsidiaries,
that is material to the business, results of operation, prospects or financial
condition of FluoroScan: (i) any merger, consolidation, share exchange,
business combination or other similar transaction (other than the Merger);
(ii) any sale, lease, exchange, transfer or other disposition of 50% or more
of the assets of FluoroScan and its subsidiaries in a single transaction or
series of transactions; or (iii) the acquisition by a person or entity, or any
"group" (as such term is defined under Section 13(d) of the Exchange Act and
the rules and regulations thereunder) of beneficial ownership of 33 1/3% or
more of the shares of FluoroScan Common Stock, whether by tender offer,
exchange offer or otherwise. The merger cancellation fees described above
could have the effect of discouraging a third party from pursuing a takeover
or other acquisition transaction involving FluoroScan because the cost of such
takeover or other acquisition transaction, if successful, would be increased
by the amount of such fees.
 
  In the event of a termination of the Merger Agreement by FluoroScan as a
result of a breach by Hologic or Merger Sub, Hologic shall pay to FluoroScan
up to $1.5 million for all documented fees and expenses incurred by FluoroScan
(including the reasonable fees and expenses of counsel, accountants,
consultants and advisors) in connection with the Merger Agreement and the
transactions contemplated thereby.
 
OPTION AGREEMENT WITH CERTAIN STOCKHOLDERS
 
  On July 18, 1996, Hologic entered into a Stockholder Option Agreement with
Messrs. Grossman and Issette (the "Stockholder Option Agreement"). Under the
Stockholder Option Agreement, Messrs. Grossman and Issette have granted
Hologic an option in certain circumstances where the Termination Fee is
payable, to purchase the shares of FluoroScan Common Stock held by them at an
exercise price equal to the Conversion Ratio. The number of shares of
FluoroScan Common Stock covered by the Stockholder Option Agreements is
1,467,152 which constitutes approximately 31.7% of the number of outstanding
shares of FluoroScan Common Stock on the Record Date.
 
CONVERSION OF SHARES; PROCEDURES FOR EXCHANGE OF CERTIFICATES
 
  The conversion, at the Conversion Ratio, of FluoroScan Common Stock into
shares of Hologic Common Stock will occur automatically at the Effective Time.
 
  As soon as practicable after the Effective Time, a transmittal letter will
be mailed by American Stock Transfer & Trust Company (the "Exchange Agent") to
each stockholder of FluoroScan informing such stockholder of the procedures to
follow in forwarding his or her certificates for FluoroScan Common Stock to
the Exchange Agent. Upon receipt of such certificates, the Exchange Agent will
deliver whole shares of Hologic Common Stock to such stockholder and cash in
lieu of fractional shares pursuant to the terms of the Merger Agreement and in
accordance with the transmittal letter, together with any dividends or other
distributions to which such stockholder is entitled, without interest. For a
description of how the amount of cash in lieu of fractional shares will be
determined, see "The Merger Agreement and Related Transactions--General."
 
  If any issuance of shares of Hologic Common Stock in exchange for shares of
FluoroScan Common Stock is to be made to a person other than the holder of
FluoroScan Common Stock in whose name the certificate is registered at the
Effective Time, it will be a condition of such exchange that the certificate
so surrendered be properly endorsed or otherwise in proper form for transfer
and that the holder of FluoroScan Common Stock requesting such issuance either
pay any transfer or other tax required or establish to the satisfaction of
Hologic that such tax has been paid or is not payable.
 
  After the Effective Time, there will be no further transfers of FluoroScan
Common Stock on the stock transfer books of FluoroScan. If a certificate
representing FluoroScan Common Stock is presented for transfer, it will be
 
                                      39
<PAGE>
 
canceled and a certificate representing the appropriate number of whole shares
of Hologic Common Stock and cash in lieu of fractional shares and any
dividends and distributions will be issued in exchange therefor, without
interest.
 
  After the Effective Time and until surrendered, shares of FluoroScan Common
Stock will be deemed for all corporate purposes, other than the payment of
dividends and distributions, to evidence ownership of the number of whole
shares of Hologic Common Stock into which such shares of FluoroScan Common
Stock were converted at the Effective Time. No dividends or other
distributions, if any, payable to holders of Hologic Common Stock will be paid
to the holders of any certificates for shares of FluoroScan Common Stock until
such certificates are surrendered. Upon surrender of such certificates, all
such declared dividends and distributions payable after the Effective Time
will be paid to the holder of record of the whole shares of Hologic Common
Stock represented by the certificate issued in exchange therefor, without
interest.
 
  HOLDERS OF FLUOROSCAN COMMON STOCK SHOULD NOT FORWARD STOCK CERTIFICATES TO
THE EXCHANGE AGENT UNTIL THEY HAVE RECEIVED TRANSMITTAL LETTERS. HOLDERS OF
FLUOROSCAN COMMON STOCK SHOULD NOT RETURN STOCK CERTIFICATES WITH THE ENCLOSED
PROXY CARD.
 
CERTAIN FEDERAL INCOME TAX MATTERS
 
  Set forth below is a discussion of certain federal income tax consequences
of the Merger to stockholders of FluoroScan who hold shares as a capital
asset. The discussion does not address the tax consequences that may be
relevant to a particular stockholder subject to special treatment under
certain federal income tax laws, such as dealers in securities, banks,
insurance companies, tax-exempt organizations, non-United States persons,
stockholders who acquired their shares of FluoroScan Common Stock pursuant to
the exercise of options or otherwise as compensation, and persons holding
(directly or indirectly) five percent or more of the outstanding shares of
Hologic Common Stock following the Merger. In addition, the following
discussion does not address the tax consequences of the Merger arising under
the laws of any state, local or foreign jurisdiction or the tax consequences
of transactions effectuated prior or subsequent to or concurrently with the
Merger (whether or not such transactions are in connection with the Merger),
including, without limitation, transactions in which FluoroScan Common Stock
is acquired or shares of Hologic Common Stock are disposed of. Moreover, the
tax consequences to holders of options or warrants are not discussed. The
discussion is based upon the Code, treasury regulations thereunder and
administrative rulings and court decisions as of the date hereof. All of the
foregoing are subject to change, possibly with retroactive effect, and any
such change could affect the continuing validity of this discussion.
FluoroScan does not intend to request a ruling from the Internal Revenue
Service ("IRS") with respect to the Merger, and opinions of counsel are not
binding on the IRS or the courts.
 
  FLUOROSCAN'S STOCKHOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS
CONCERNING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES OF THE
MERGER TO THEM IN THEIR PARTICULAR CIRCUMSTANCES.
 
  This summary is based upon the advice of Brown, Rudnick, Freed and Gesmer,
counsel to Hologic, and Katten Muchin & Zavis, counsel to FluoroScan, one or
both of whom will be delivering opinions to Hologic and FluoroScan that,
subject to the limitations and qualifications referred to therein, the Merger
will constitute a reorganization within the meaning of Section 368(a) of the
Code (a "Reorganization"). Qualification of the Merger as a Reorganization
will generally result in the following federal income tax consequences:
 
    (a) No gain or loss will be recognized by FluoroScan, Hologic or Merger
  Sub solely as a result of the consummation of the Merger;
 
    (b) No gain, loss or income will be recognized by holders of FluoroScan
  Common Stock upon the receipt of shares of Hologic Common Stock in exchange
  therefor (except with respect to any cash received by holders of FluoroScan
  Common Stock in respect of fractional shares);
 
 
                                      40
<PAGE>
 
    (c) The aggregate tax basis of the shares of Hologic Common Stock
  received by a holder of FluoroScan Common Stock in the Merger will be the
  same as the aggregate tax basis of FluoroScan Common Stock surrendered in
  exchange therefor by such stockholder, reduced by amounts allocable to
  fractional shares for which cash is to be received;
 
    (d) The holding period of the shares of Hologic Common Stock received in
  the Merger by the holders of FluoroScan Common Stock will include the
  period during which the shares of FluoroScan Common Stock surrendered in
  exchange therefor were held, provided that FluoroScan Common Stock is held
  as a capital asset in the hands of the holders of FluoroScan Common Stock
  on the date of the exchange; and
 
    (e) Cash payments received by holders of FluoroScan Common Stock in lieu
  of a fractional share will be treated as if such fractional share of
  Hologic Common Stock had been issued in the Merger and then redeemed by
  Hologic. A holder of FluoroScan Common Stock receiving such cash will
  generally recognize gain or loss, upon such payment, measured by the
  difference (if any) between the amount of cash received and the basis in
  such fractional share.
 
  The foregoing opinions are based upon the representation of management of
Hologic that the Hologic Purchase Rights have no value and that the likelihood
of their being exercisable is both speculative and remote. In the event that
such rights were determined to have value, the FluoroScan shareholders might
recognize taxable income, limited in the case of each shareholder to the
lesser of the gain realized upon the Merger or the value of the rights.
 
  In rendering their opinions, Brown, Rudnick, Freed and Gesmer and Katten
Muchin & Zavis will rely upon information contained in this Proxy
Statement/Prospectus, representations and warranties of FluoroScan and Hologic
and certificates of officers of FluoroScan and Hologic with regard to the
particular facts and circumstances applicable to the transactions
contemplated, without independent verification. In particular, the opinion
will be issued in reliance on certain representations from FluoroScan and
Hologic and certain principal stockholders of FluoroScan and Hologic with
respect to the satisfaction of the continuity of interest requirement of the
regulations interpreting Section 368 of the Code, and certain other matters.
 
  A successful IRS challenge to the reorganization status of the Merger would
result in a holder of FluoroScan Common Stock recognizing gain or loss with
respect to each share of FluoroScan Common Stock surrendered equal to the
difference between the stockholder's basis in such share and the fair market
value, as of the date of the Merger, of the shares of Hologic Common Stock
received in exchange therefor. In such event, a stockholder's aggregate basis
in the shares of Hologic Common Stock so received would equal its fair market
value, and the stockholder's holding period for such stock would begin the day
after the Merger.
 
ACCOUNTING TREATMENT
 
  The Merger is intended to qualify as a pooling of interests for accounting
and financial reporting purposes. Hologic and FluoroScan have been advised by,
and will receive letters from Arthur Andersen LLP, Hologic's independent
accountants, and BDO Seidman, LLP, FluoroScan's independent accountants, to
the effect that, the Merger will qualify as a pooling of interests for
accounting and financial reporting purposes. Under this method of accounting,
the recorded assets and liabilities of Hologic and FluoroScan will be carried
forward to Hologic at their recorded amounts, the consolidated income of
Hologic will include income of Hologic and FluoroScan for the entire fiscal
year in which the combination occurs and the reported income of the separate
companies for prior periods will be combined and restated as consolidated
income of Hologic. See "The Merger and Related Transactions--Conditions to the
Merger" and "Hologic, Inc. Unaudited Pro Forma Combined Condensed Financial
Statements."
 
  The respective affiliates of Hologic and FluoroScan have each executed
written agreements to the effect that such person will not transfer shares of
Hologic Common Stock or FluoroScan Common Stock until the date that Hologic
publishes financial statements which reflect 30 days of post-merger combined
continued operations of Hologic (which agreements relate to the ability of
Hologic to account for the Merger as a pooling of interests).

FEDERAL SECURITIES LAW CONSEQUENCES
 
  All shares of Hologic Common Stock to be issued in the Merger will be freely
transferable, except that any shares of Hologic Common Stock received by
persons who are deemed to be "affiliates" (as such term is defined under the
Securities Act) of FluoroScan or Hologic prior to the Merger may be sold by
them only in transactions permitted by the resale provisions of Rule 145 under
the Securities Act with respect to affiliates of FluoroScan, or Rule 144 under
the Securities Act with respect to persons who are or become affiliates of
Hologic, or as otherwise permitted under the Securities Act. Persons who may
be deemed to be affiliates of FluoroScan or Hologic generally include
individuals or entities that control, are controlled by, or are under common
control with, such party and may include certain officers and directors of
such party as well as principal stockholders of such party.
 
  Affiliates of FluoroScan may not sell their shares of Hologic Common Stock,
except pursuant to an effective registration statement under the Securities
Act covering such shares or in compliance with Rule 145 (or Rule 144 under the
Securities Act in the case of persons who are or become affiliates of Hologic)
or another applicable exemption from the registration requirements of the
Securities Act. In general, under Rule 145, for two years following the
Effective Time, an affiliate of FluoroScan prior to the Merger (together with
certain related persons) will be entitled to sell shares of Hologic Common
Stock acquired in the Merger only through unsolicited "broker transactions" or
in transactions directly with a "market maker," as such terms are defined in
Rule 144. Additionally, the number of shares to be sold by such an affiliate
(together with certain related persons and certain persons acting in concert)
within any three-month period for purposes of Rule 145 may not exceed the
greater of 1% of the outstanding shares of Hologic Common Stock or the average
weekly trading volume of the shares of Hologic Common Stock during the four
calendar weeks preceding such sale. Rule 145 will only remain available,
however, to persons who were affiliates of FluoroScan prior to the Merger, if
Hologic remains current with its informational filings with the Commission
under the Exchange Act. Two years after the Effective Time, a person who was
an affiliate of FluoroScan prior to the Merger will be able to sell shares of
Hologic Common Stock without regard to such manner of sale or volume
limitations, provided that Hologic is current with its Exchange Act
informational filings and such person is not then an affiliate of Hologic.
Three years after the Effective Time, a person who was an affiliate of
FluoroScan prior to the Merger will be able to sell such shares of Hologic
Common Stock without any restrictions so long as such person had not been an
affiliate of Hologic for at least three months prior to the sale.
 
REGULATORY MATTERS
 
  Neither Hologic nor FluoroScan is aware of any governmental or regulatory
approvals required for the consummation of the Merger other than (i)
compliance with the HSR Act, as described below, (ii) compliance with
applicable securities laws and (iii) certain filings under Delaware Law.
 
  The Merger is subject to the HSR Act and the rules and regulations
thereunder, which provide that certain transactions may not be consummated
until required information and materials have been furnished to the Antitrust
Division of the Department of Justice (the "Antitrust Division") and the
Federal Trade Commission
(the "FTC") and certain waiting periods have been expired or been terminated.
On August 1, 1996, Hologic and FluoroScan filed the required information and
materials with the Antitrust Division and FTC and requested early termination
of the waiting period under the HSR Act.
 
  Hologic's and FluoroScan's request for early termination of the waiting
period under the HSR Act has not yet been granted, however, neither party is
aware of any reason why the Antitrust Division or the FTC will deny the
request for early termination. The termination of the HSR Act waiting periods
does not preclude the Antitrust Division or the FTC from challenging the
Merger (or any part thereof) on antitrust grounds. Accordingly at any time
before or after the Effective Time, either the Antitrust Division or the FTC
could take such action under the antitrust laws as it deems necessary or
desirable in the public interest, or certain other persons, including the
attorney general of one or more states or private parties, could take action
under the antitrust laws, including seeking to enjoin the Merger (or any part
thereof). There can be no assurance that a challenge to the Merger will not be
made or, if such a challenge is made, that Hologic or FluoroScan will prevail.

                         INFORMATION REGARDING HOLOGIC
 
  Hologic is a leading international developer, manufacturer and marketer of
X-ray bone densitometers which precisely measure bone density for use in the
diagnosis and monitoring of metabolic bone diseases such as osteoporosis.
Hologic pioneered the use of dual-energy X-ray absorptiometry ("DXA") to
measure bone density, introducing the first DXA bone densitometer in 1987.
Since this introduction, DXA systems have become the standard for measuring
bone density. In 1995, Hologic introduced its fourth generation of DXA bone
densitometers, its clinically oriented QDR 4500 ACCLAIM product line.
 
  To address the growing clinical market for the early diagnosis and
monitoring of osteoporosis, Hologic is developing products that it believes
will complement its DXA product line. In December 1994, Hologic acquired the
ultrasound bone analyzer business of Walker Sonix, Inc. ("Walker Sonix").
Hologic is developing an enhanced ultrasound bone analyzer, the Sahara, which
it has recently introduced in clinical test sites in the United States and
certain international markets. Hologic believes that ultrasound systems could
represent a relatively low cost, compact, easy-to-use, non-X-ray based,
screening technique to assist in the initial diagnosis of osteoporosis. In
September 1994, Hologic began a joint development effort with Serex, Inc.
("Serex") to develop a diagnostic strip test to detect biochemical markers
that indicate the rate of a patient's bone loss. The strip test is being
designed to provide a physician with a real-time means of measuring a
patient's biochemical response to osteoporosis therapies and compliance with
those therapies, as a complement to periodic bone density measurements.
Hologic and Serex have also recently entered into an agreement in principle
with a leading pharmaceutical company to develop and market an over-the-
counter version of the strip test.
 
BACKGROUND
 
  Osteoporosis. Osteoporosis is a condition characterized by reduced bone
density that leads to an increased risk of fractures. Bone is a dynamic organ
that is maintained through a process referred to as remodeling in which old
bone is removed (resorption) and new bone is formed. In early adulthood, the
levels of bone resorption and bone formation are generally balanced, with the
quantity and distribution of bone throughout the body varying over time
depending on muscle mass, strength and use. When remodeling does not function
properly, and resorption exceeds formation, the result is a net loss of bone
mass and density, often causing diminished structural integrity of the
skeleton (particularly of the trabecular "spongy" bone) and an increased risk
of fracture.
 
  According to the National Osteoporosis Foundation (the "NOF"), 25 million
Americans, 80% of whom are women, and approximately 200 million people
worldwide, suffer from osteoporosis. Osteoporosis typically develops silently
over a period of years, eventually progressing to a point where a fracture can
easily occur, causing pain and disability. The post-menopausal female
population has the highest incidence of osteoporosis and the highest rate of
morbidity (loss of quality of life) and mortality due to osteoporosis. The NOF
estimates that in the United States osteoporosis contributes to more than 1.3
million fractures annually, a majority of which were of the spine and hip, and
that related direct health care and indirect productivity costs in 1987 were
approximately $10 billion. Hip fractures lead to the most serious
consequences. According to the NOF, as many as one in every five hip fracture
patients dies from complications within a year after fracture, one in every
four requires long-term care and an even higher percentage of hip fracture
patients never return to an active and independent lifestyle.
 
  Until recently, osteoporosis was thought to be an untreatable consequence of
aging. Hologic believes that the recent development and introduction of new
drug therapies, the aging of the population, and an increased focus on women's
health issues and preventive medical practices has created a growing awareness
among patients and physicians that osteoporosis is treatable.
 
  Therapies. Hologic believes that over 70 clinical studies are currently in
progress to assess the safety and effectiveness of new therapies to treat
osteoporosis. However, prior to 1995, there were only two approved drug
treatments for osteoporosis in the United States, hormone replacement therapy,
using estrogen and related
 
                                      50
<PAGE>
 
hormones ("HRT"), and calcitonin, with the most widely prescribed treatment
being HRT. Patient concerns regarding complications related to prolonged use
of HRT have contributed to a low compliance rate. Until recently, calcitonin
was available only in an injectable form, a delivery method that has
contributed to low patient compliance. Although HRT and calcitonin have
generally been shown in clinical trials to slow or stop the loss of bone mass,
these therapies have not been proven to restore bone mass.
 
  In September 1995, the FDA approved Merck's drug Fosamax for the treatment
of established osteoporosis in post-menopausal women. Fosamax is a
bisphosphonate that acts by coating the bone surface and inhibiting bone
resorption. Merck reported that in clinical studies of Fosamax conducted in
over 16 countries post-menopausal patients with established osteoporosis who
were treated with Fosamax gained on average of 7-10% bone mass in the spine
and 7-8% bone mass in the hip over a three-year period compared to patients
treated with placebo, and that Fosamax reduced the number of new vertebral
fractures (fractures of the spine) by approximately 48% compared with placebo.
Merck is conducting ongoing clinical trials to determine the effectiveness of
Fosamax in preventing osteoporosis, and in April 1996 filed a supplement with
the FDA for approval of the use of Fosamax for that purpose. Fosamax is also
approved in approximately 40 countries in addition to the United States. In
March 1996, Merck reported that more than 475,000 patients worldwide were
taking Fosamax.
 
  Other therapies cleared by the FDA to treat osteoporosis in 1995 are a one-
tablet hormone replacement therapy, which combines estrogen and progestin,
developed by Wyeth-Ayerst Laboratories, and an intra-nasal formulation of
calcitonin developed by Sandoz. In addition, in November 1995, an FDA advisory
committee recommended that the FDA approve slow-release sodium fluoride for
the treatment of post-menopausal osteoporosis. Additional therapies undergoing
clinical trials for the prevention or treatment of osteoporosis include
bisphosphonates being developed by Proctor & Gamble (Rasidronate), Boehringer-
Mannheim (Ibandronate) and Sanofi (Tiludronate), and estrogen analogues or
anti-estrogens being developed by Eli Lilly (Raloxifene) and Pfizer
(Draloxifene).
 
  In several European countries, Japan and other international markets, there
has been an earlier availability and greater acceptance of osteoporosis
therapies. Some of these therapies include estrogens, bisphosphonates,
calcitonins, vitamin D compounds and ipriflavone.
 
  The timing of when and where new drugs will become commercially available,
if ever, is uncertain. However, Hologic believes that there will be broadened
and new approvals of osteoporosis therapies for both treatment and prevention
which should positively impact the bone assessment market worldwide.
 
  Diagnosis and Monitoring of Osteoporosis. There are a number of different
technologies that are available that can be used to assess bone mineral
status.
 
  Since the introduction of the first DXA bone densitometer by Hologic in
1987, dual energy X-ray absorptiometry has become the primary means of
measuring bone density. Prior to that introduction, the most widely used bone
density measuring technique for the hip and spine was dual photon
absorptiometry (DPA). DPA systems were not very precise and required
relatively long scanning times and the use of an expensive radioactive source
that required periodic replacement. In contrast, DXA systems have much higher
precision, require significantly shorter scanning times and do not require a
radioactive source. DXA systems require a low patient radiation exposure. The
most advanced DXA systems can be used to measure the bone density of the whole
body, or any site, including the most important fracture sites of the hip or
spine. As a result of their precision and versatility, DXA systems have become
the predominant means of evaluating low bone density before fractures occur
and monitoring changes in a patient's bone density in response to therapies.
 
  Other bone assessment technologies include single photon absorptiometry
(SPA), radiographic absorptiometry (RA), quantitative computed tomography
(QCT), quantitative ultrasound and biochemical markers.
 
  Single photon absorptiometry was introduced in the 1960s and represents an
effective method of measuring bone density at a peripheral site of the
skeleton (forearm or heel), although it cannot be used to measure the
 
                                      51
<PAGE>
 
most important fracture sites of the spine or hip. SPA systems also have the
added inconvenience of requiring the patient to place the site being scanned
in water or other tissue-equivalent media to achieve precision. SPA, however,
does represent a relatively inexpensive and valuable tool in the diagnosis of
osteoporosis with reasonable precision and low radiation exposure.
 
  Quantitative computed tomography was introduced in the mid 1970s and can
measure bone density by using a CT scanner to determine both the patient's
bone density and bone distribution in three dimensions. QCT, however, has
remained limited in clinical use because of its relatively high radiation dose
and the high cost of CT scanner equipment.
 
  Radiographic absorptiometry, also introduced in the 1970s, measures bone
density from two X-ray images (radiographs) of the hand placed alongside a
calibration device using a conventional X-ray machine. The radiographs are
sent to a central processing laboratory where a computer measures the density
of the bone. The precision of this technique is comparable to SPA
measurements. An advantage of this system is that it does not require any
additional capital investment, as traditional X-ray equipment can be used to
obtain the radiographs. The technique, however, cannot be used to measure and
monitor the hip or spine. Also, because the radiograph must be sent to a
laboratory for testing, it does not provide a real-time assessment of bone
density, and, if the test is positive, a follow-up consultation is required.
Hologic believes that RA will be useful in rural areas where there may not be
a sufficient concentration of patients to justify a capital investment in DXA
bone density measuring equipment.
 
  Ultrasound has long been used in medical testing. However, the use of
ultrasound for the detection of osteoporosis was not commercially introduced
until recently, and then only in certain foreign countries. Ultrasound
measurement has concentrated mainly on the calcaneous (the heel), which is
comprised primarily of trabecular bone, as a measuring site. Initial clinical
trials of ultrasound systems have indicated a significant association of low
ultrasonic bone measurements of the calcaneous and the risk of fracture. The
latest developments in hardware and software, resulting in enhanced precision
and ease of use, are currently making ultrasound techniques an option for the
diagnosis of osteoporosis. Major advantages of ultrasound examination are the
complete absence of radiation and the small size and low cost of the
equipment. Ultrasound devices do not use X-rays in making their measurements
and therefore do not require X-ray licensing or registered operators. However,
because ultrasound bone measurements currently are not as precise as DXA and
other measurements, they are less reliable for continued monitoring of small
changes in bone density or for assessing the response to therapies. In
addition, they are generally limited to measurements at peripheral sites, not
the more important spine or hip fracture sites. Accordingly, Hologic believes
that the most likely use for ultrasound techniques currently employed and
under development by Hologic and others will be for initial screening for
osteoporosis and not for continued monitoring of changes in bone density or
the response to therapies.
 
  Biochemical markers are substances that are produced within the body that
correlate directly or indirectly to disease or bodily function. A number of
biochemical markers have been discovered that can be used to measure the rate
of bone resorption or formation. These measurements, while not measuring bone
density, can provide a means to assess quickly (within approximately three
months) the effectiveness of treatment and patient compliance with therapies
for osteoporosis. A baseline and subsequent bone density tests (as frequently
as annually) must be used in conjunction with biochemical marker measurements
to assess fully the bone density of the patient. Because biochemical markers
cannot be used independently to diagnose osteoporosis or risk of fracture, or
to monitor a patient's changes in bone density as a result of therapy or
otherwise, Hologic believes that biochemical marker tests, including those
being developed by Hologic, will complement and not replace densitometry.
 
  Market. Hologic believes that the clinical market for osteoporosis
diagnostic and monitoring products is expanding due to the recent development
and introduction of new drug therapies to treat osteoporosis, the more
widespread and increased reimbursement for bone density examinations, the
aging of the population, and an increased focus on women's health issues and
preventive medical practices. All of these factors have led to an increased
awareness by women and primary care providers, such as gynecologists and
family physicians, that
 
                                      52
<PAGE>
 
osteoporosis is a treatable disease and that measurement of bone density is an
integral component of diagnosis and monitoring of this disease.
 
  Upon obtaining FDA approval for Fosamax in September 1995, Merck launched an
extensive educational campaign to increase patient and physician awareness
that osteoporosis is a treatable disease. In connection with this effort,
Merck is promoting the use of DXA and other techniques to diagnose and monitor
osteoporosis and the effects of drug therapies. Hologic believes that this
comprehensive Merck program will further accelerate the growth of the bone
densitometer and related markets. Currently, Fosamax is only approved for use
by patients with established osteoporosis. However, Merck and other drug
companies are conducting ongoing clinical trials to establish the efficacy of
drug therapies to prevent osteoporosis in high risk patients. In April 1996,
Merck filed a supplement with the United States FDA for a new indication for
Fosamax--the prevention of osteoporosis in women. Such approval would increase
the need for patient testing and monitoring at an earlier age, before a
patient is afflicted with osteoporosis.
 
  In the United States, the Health Care Finance Administration, which
establishes guidelines for the reimbursement of health care providers treating
Medicare and Medicaid patients, provided validation for DXA bone densitometry
examinations as a clinically useful procedure by recommending the
reimbursement for DXA bone evaluations at the rate of $68 per scan effective
April 1994. Effective January 1995, HCFA furthered the clinical use of DXA
evaluations by increasing the recommended reimbursement rate to $124. In part
as a result of the reimbursement policy recommendations implemented by HCFA,
bone density examinations are paid for by many private third party insurers in
the United States.
 
  With the recent increase in reimbursement levels in the United States, and
the FDA approval of Fosamax and other drug therapies, Hologic believes that
the United States market for bone densitometers and other methods of bone
mineral assessment will expand from the hospitals, large clinics, research
institutions and imaging and women's centers, to the larger potential market
of primary care providers, including gynecologists and family physicians.
 
  In several European countries, Japan and other international markets, there
has been a greater availability or acceptance of osteoporosis therapies and an
earlier adoption of reimbursement for bone densitometry exams. Countries in
which reimbursement for the use of X-ray bone densitometers has been approved
include Belgium, Brazil, Canada, Germany, Greece, Japan, South Korea, Spain
and Switzerland. In addition, the Japanese government has been actively
supporting an educational program to promote public awareness of osteoporosis
as a treatable disease. In Latin American countries such as Argentina, Brazil
and Chile, and in Pacific Rim countries, such as Australia, The Peoples
Republic of China, South Korea and Taiwan, there is a growing use of
osteoporosis therapies and an expanding market for osteoporosis diagnostic and
monitoring equipment.
 
HOLOGIC'S STRATEGY
 
  Hologic's goal is (i) to become the leading fully-integrated supplier of
technologically advanced, innovative and clinically valuable diagnostic
systems and tests that address the growing market for osteoporosis prevention
and treatment, and (ii) to diversify into other medical device markets which
it believes will be complementary to its current business. Key elements of
this strategy are as follows:
 
  Maintain and Enhance DXA Technological Leadership. Hologic has been a
pioneer in the development of DXA bone densitometers. Since commercially
introducing the first DXA bone densitometer in 1987, Hologic introduced a bone
densitometer capable of assessing the bone density of the entire body in 1989,
introduced the first bone densitometer capable of taking supine lateral
measurements of the spine in 1991 and introduced its fourth generation
clinically-oriented QDR 4500 ACCLAIM series of bone densitometers in 1995. The
ACCLAIM series integrates Hologic's most advanced X-ray technology into a
compact package that facilitates installation in a standard examination room.
Hologic believes that because of their technological features, its DXA systems
have been and continue to be the most widely used bone densitometers for
clinical studies
 
                                      53
<PAGE>
 
involving the emerging drug therapies for osteoporosis. Hologic intends to
continue to enhance and expand upon its core technical expertise to develop
increasingly efficient and cost-effective DXA bone densitometer solutions.
 
  Expand Range of Complementary Bone Diagnostic and Monitoring
Products. Hologic believes that a significant market exists for relatively
low-cost products that assess bone density, employ technologies that do not
use X-rays or other ionizing radiation, and may be used in a doctor's office.
In order to address this market, Hologic is pursuing the development and
acquisition of products that use ultrasound and biochemical markers to assess
bone mineral status. Recent milestones achieved by Hologic in connection with
this pursuit include the following:
 
  .  In December 1994, Hologic acquired the Walker Sonix ultrasound bone
     analyzer business.
 
  .  In September 1995, Hologic introduced a prototype of the Sahara, an
     internally developed advanced ultrasound bone analyzer that does not
     require the use of water, at the American Society of Bone Mineral
     Research.
 
  .  In September 1994, Hologic began a joint development effort with Serex
     to develop a low-cost biochemical marker strip test.
 
  .  In December 1995, Hologic and Serex further entered into an agreement in
     principle with a major pharmaceutical company to develop an over-the-
     counter version of the biochemical marker strip test.
 
Hologic believes that if it is able to develop these products successfully it
will be in a position to offer a full range of diagnostic and monitoring
products for the growing osteoporosis market. Hologic also plans to pursue
other product development and market opportunities in the area of bone
assessment that Hologic identifies as promising.
 
  Expand United States Distribution. Hologic believes that the continued
development of its distribution network in the United States will be an
important factor in its continued success. Hologic has developed an
experienced 61 person direct sales force covering the United States, has
recently entered into agreement with Leisegong Medical Systems for the
exclusive distribution of certain of Hologic's products to gynecologists and
primary care physicians, and plans to enhance further its distribution
capabilities in the United States through a combination of an expansion of its
sales force and strategic alliances with companies with established
distribution channels in the various market segments for Hologic's products.
 
  Continued International Expansion. International sales have accounted for
approximately 56% and 75% of Hologic's sales in the first six months of fiscal
1996 and fiscal 1995, respectively, with such sales being made predominantly
to countries in Western Europe and Japan. In fiscal 1995, Hologic increased
its efforts to expand its market penetration into new markets in Latin
America, including Argentina, Brazil and Chile, and along the Pacific Rim,
including Australia, The Peoples Republic of China, South Korea and Taiwan.
Hologic intends to continue to seek to expand sales in these and other less-
developed territories.
 
  Diversification into Complementary Markets. Hologic is seeking to leverage
its medical device development, manufacturing and distribution expertise to
expand, through acquisition or strategic alliances, into complementary
markets. Such markets could include other diagnostic or imaging markets, as
represented by FluoroScan, or other women's healthcare markets.
 
  There can be no assurance that Hologic will be able to implement
successfully any of its strategies on a timely basis, if at all, or if
successfully implemented, that any of these strategies will enable Hologic to
maintain or enhance its growth.
 
BONE ASSESSMENT PRODUCTS
 
  Hologic's products include a family of DXA bone densitometers which are used
for the precise measurement of bone density to assist physicians in the
diagnosis and monitoring of metabolic bone diseases such as osteoporosis.
Since commercially introducing the first DXA bone densitometer in 1987,
Hologic
 
                                      54
<PAGE>
 
introduced its first bone densitometer capable of assessing the bone density
of the entire body in 1989, introduced the first bone densitometer capable of
taking lateral measurements of the spine in 1991, and, in 1995, introduced its
new QDR 4500 ACCLAIM fourth generation series of bone densitometers, which
integrates Hologic's most advanced X-ray technology into a compact package
that facilitates installation in a standard examination room. The United
States list prices for Hologic's DXA bone densitometers range from
approximately $55,000 to $165,000 per system.
 
  Hologic believes that a significant market may exist for relatively low-cost
products that assess bone mineral status, employ technologies that do not use
ionizing radiation and may be used in a doctor's office. In order to address
this market, Hologic has acquired or is developing products that use
ultrasound or measure biochemical markers to assist in the assessment of bone
mineral status.
 
  QDR X-Ray Bone Densitometers. Since Hologic's first commercial shipment of a
DXA system in October 1987, Hologic has sold more than 2,800 DXA systems.
Hologic believes that its systems' performance advantages and their early
adoption by leading clinical investigators have led to their market
acceptance. Hologic's DXA systems have been purchased for multiple-site
studies sponsored by the pharmaceutical companies and by the United States
government for evaluation of the incidence and treatment of osteoporosis. In
addition, pharmaceutical companies have promoted the purchase of the systems
for use by physicians to assist in the diagnosis and treatment of
osteoporosis.
 
  Advantages of Hologic's DXA systems include high precision (consistency from
test to test), low patient radiation exposure equivalent to 1/10th of a
conventional chest X-ray, a relatively fast scanning time, low operating cost,
no radioactive source and the ability to measure bone density of the most
important fracture sites, the spine and hip. Studies conducted by Hologic and
independent investigators have demonstrated that the systems can detect a
change in spine bone density with a precision error of less than 1%.
 
  All Hologic's DXA systems employ Hologic's patented Automatic Internal
Reference System, which continuously calibrates each patient's bone density
measurement to a known standard. This system virtually eliminates errors that
might result from manual calibration and saves operators the time-consuming
task of calibrating several times a day. The system automatically compensates
for drift in the X-ray system, detectors or other electronic components which
ensures long-term measurement stability.
 
  Each of Hologic's DXA systems contains an X-ray source mounted beneath the
patient, who is positioned lying on her back. The X-ray source generates
alternating high and low energy pulses in a thin beam that passes through
Hologic's patented Automatic Internal Reference System and then through the
patient to an X-ray detector mounted above the patient. Controlled by a
computer, the X-ray source and detector are moved in tandem across the
patient. When the X-ray beam is detected, it contains information about the X-
ray absorbing characteristics of both the patient and the calibration
materials in the Automatic Internal Reference System at each of the two levels
of radiation. The system converts this information into a digital format which
is processed and analyzed by a computer and displayed on a high-resolution
color monitor, both of which are incorporated into the system.
 
  Hologic has invested substantial resources in developing operating and
applications software for its systems. The software includes calibration
software, automated scan and analysis programs for each scan site, a patient
data base manager that archives all raw data for later retrieval and analysis
and allows the operator to review the current image with an earlier image of
the same patient.
 
  Initial DXA systems developed by Hologic employed a single narrow pencil
beam detected by one receptor. In 1991, Hologic introduced the first bone
densitometer employing a high density fan shaped X-ray beam that is detected
by an array of receptors. This configuration enables the system to obtain
better quality images with improved spatial resolution, significantly faster
scanning time and higher patient throughput compared to single-beam systems.
Moreover, for standard spine and hip scans, fan beam technology can reduce
scan time by a factor of more than 25 compared to older single-beam scanning
systems.
 
                                      55
<PAGE>
 
  Hologic developed this fan beam technology to perform lateral (side-to-side)
scans of the lower spine, in addition to the posterior-anterior (back-to-
front) measurements performed by Hologic's pencil beam systems. The earliest
and most dramatic loss of bone density in the spine occurs primarily in the
spine's soft (trabecular) bone, which is positioned directly behind the hard
(cortical) bone when taking back-to-front measurements. This results in bone
density measurements that average the density of the soft and hard bone and
tends to mask changes in the soft bone. A lateral scan permits the imaging and
measurement of the spine's soft bone with only limited interference from hard
bone. In addition, a lateral scan reduces the interference caused by abnormal
accumulation of bone and calcium deposits in and around the spine.
 
  Numerous scientific articles have established lateral bone densitometry,
using supine patient positioning, as a highly precise and more diagnostically
sensitive way to measure the spine than conventional posterior-anterior
examinations. Lateral densitometry also eliminates scan artifacts such as
aortic calcification or degenerative disease of the spinal processes that can
distort conventional posterior-anterior measurements.
 
  In November 1994, Hologic introduced the QDR 4500A ACCLAIM at the annual
meeting of the Radiological Society of North America and in January 1995
obtained FDA clearance to sell the system in the United States. See
"Information Regarding Hologic--Regulation."
 
  Hologic's QDR 4500 ACCLAIM series of bone densitometers offers rapid
scanning and high resolution imaging using the latest available fan beam and
high density, solid-state multi-detector array technology. In addition, the
QDR 4500 ACCLAIM series is built in modular configurations that allow
customers to add new features and capabilities, while protecting their
investment in the equipment and patient data.
 
  An important feature of the QDR 4500A and QDR 4500SL is their ability to
perform lateral (side-to-side) scans of the lower spine, without turning the
patient on her side, in addition to the posterior-anterior (back-to-front)
measurements. The QDR 4500A and QDR 4500SL ACCLAIM are capable of producing
high quality images of the spine, lateral spine, hip and other skeletal sites.
The ACCLAIM's scan arm allows for multiple scan views without patient
repositioning. The images produced can be combined with capabilities that
enable vertebral dimensions to be determined with a radiation dose
approximately ten to 100 times lower than that of conventional chest X-rays.
Using the QDR 4500A or the QDR 4500SL, high-quality lateral images of the
entire spine can now be obtained in as little as ten seconds.
 
  The ACCLAIM systems are designed to require less floor space than any other
bone densitometer capable of taking hip and spine measurements. The special
tabletop design and motorized scanner C-arm allow the QDR 4500C and QDR 4500SL
to be installed in a standard 8ft x 8ft examination room (the QDR 4500W and
QDR 4500A require an 8ft X 10ft room). Installation requirements for any of
the ACCLAIM bone densitometers are minimal and normally do not require special
electrical, structural or lead-shielding preparation. In addition to their
small size, the QDR 4500 series offers virtually silent operation.
 
  The ACCLAIM series has replaced Hologic's QDR 1500, QDR 2000 and QDR
2000plus products. Hologic has retained its QDR 1000plus system as a low-price
offering. The QDR 1000plus employs Hologic's older pencil beam technology. In
the first six months of fiscal 1996, the ACCLAIM series accounted for
approximately 89% of DXA sales.
 
  Ultrasound. In December 1994, Hologic acquired the ultrasound bone analyzer
business of Walker Sonix. Walker Sonix had developed an ultrasound product
line to assess bone mineral status of the heel. The location of the heel
facilitates easy coupling of the ultrasound transducers at a site with a
relatively low amount of overlying soft tissue. The heel is also made up of
predominantly trabecular bone which tends to be more metabolically active. The
Walker Sonix ultrasound devices measure two parameters, Broadbased Ultrasound
Attention (BUA) and Speed of Sound (SOS) through a water medium to
characterize bone mineral status. The use of water as a medium, which is a
characteristic of other ultrasound bone analyzers, requires the patient to
place her foot in water. The use of water requires cumbersome plumbing and
cleaning mechanisms to be incorporated in the system.
 
                                      56
<PAGE>
 
  Hologic developed internally an enhanced dry ultrasound bone analyzer,
called "Sahara" that does not require the use of water. Hologic believes that
this "dry" technology does offers further operator convenience by the
elimination of the water handling required between each patient. The
elimination of the use of water has also enabled Hologic to reduce the size
and weight of the device. In September 1995, Hologic introduced a prototype of
the Sahara at the American Society of Bone Mineral Research. Hologic initiated
clinical trials of the Sahara in the United States in the fourth quarter of
fiscal 1995 and commenced international sales of the system in the third
quarter of fiscal 1996. Commercial introduction of the system in the United
States is dependent upon FDA approval. Hologic believes that this approval
process may take as long as two to three years. There can be no assurance that
Hologic will be able to obtain FDA approval for the Sahara on a timely basis,
if at all.
 
  Recent studies have suggested that ultrasound provides good separation of
fracture populations from reference groups and suggests that this method is a
promising screening tool for evaluating a patient's fracture risk. However,
ultrasound does not allow for direct assessment of important hip and spine
fracture sites, has undocumented ability to follow the effects of therapy and
has less precision (reproducibility of results) compared to DXA measurements.
Accordingly, Hologic believes that ultrasound systems will be used
predominantly as a low cost initial screening or diagnostic tool and not as a
patient monitoring tool.
 
  Biochemical Markers. In September 1994, Hologic entered into a joint
development agreement with Serex to develop a simple strip test for use by
physicians to monitor the levels of a patient's biochemical markers that
indicate the rate of bone resorption. In December 1995, Hologic and Serex
expanded the scope of this development effort by entering into an agreement in
principle with a major pharmaceutical company to develop an over-the-counter
version of this strip test. Although biochemical markers cannot measure bone
density, Hologic believes that biochemical markers may be useful as a tool to
determine if therapy is effective. This is accomplished by comparing the
baseline level of the marker with the value obtained from a serial measurement
performed only two or three months following the start of therapy. This same
technique may be useful to evaluate patient compliance with a prescribed
therapy.
 
  Traditionally, biochemical markers of bone were performed using high
pressure liquid chromatography ("HPLC") methods conducted in a research
laboratory. HPLC procedures are complex, labor intensive requiring a highly
trained technician, relatively slow, subject to high variability and
expensive. For these reasons, biochemical markers of bone using HPLC methods
have not been used for routine clinical testing. Recently, several
immunodiagnostic tests that are antibody-based have been developed as
biochemical markers of bone remodeling. Immunodiagnostic tests may be
performed in a variety of technical formats. The format that has been
introduced by several companies is the microtitre plate system, which is used
for many different types of in-vitro diagnostic tests and is normally
performed in a reference laboratory.
 
  Serex has developed a proprietary and patented technology that enables
complex immuno-chemistry assays to be performed in a strip test format that
Hologic believes is well-suited for testing directly in the physician's office
or the home to provide a real-time assessment of bone resorption. In September
1994, Hologic purchased a minority interest in Serex and entered into a
license and supply agreement with Serex to develop a urine-based bone
resorption test deliverable in a diagnostic strip test format. Hologic
believes that other applications for biochemical markers of bone as well as
new markers are likely to be developed in the future, and under its agreement
with Serex, Hologic retains the first right of negotiation to develop and
license such tests. There can be no assurance that Serex will be able to
develop effective strip tests, either for physician or over-the-counter use,
on a timely basis, if at all, that once developed, any strip test will be
approved or cleared for sale in the United States or other jurisdictions, or
that once cleared or approved for sale any strip test will be commercially
successful.
 
OTHER PRODUCTS; SCANORA
 
  In order to take advantage of its European sales force and associated
distribution capability, in May 1993, Hologic entered into exclusive
distribution agreement with Soredex, S.A. ("Soredex"), a division of Orion
 
                                      57
<PAGE>
 
Corporation of Helsinki, Finland, to distribute Scanora, a specialized system
for taking X-ray images of the maxillo-facial anatomy (teeth, jaw and other
facial structures).
 
  The Scanora system supports more than 1,000 different image modes, including
pre-surgical planning of dental implants, reconstructive surgery and temporal
mandibular joint repair. This system provides significantly improved images of
the maxillo-facial anatomy compared to other techniques available in the
market, such as panoramic X-rays or computed tomography. Dental implant
procedures have experienced significant growth in Europe over the past five
years.
 
  Under the agreement, Hologic is the exclusive distributor of Scanora systems
in Western Europe, the Middle East and Africa, excluding South Africa and
Namibia. In addition, Hologic has non-exclusive distribution rights in several
Eastern European countries. The agreement with Soredex provides for Hologic to
purchase a minimum number of systems in each contract year. In the event that
Hologic does not achieve the minimum levels set forth under this agreement,
Soredex has the option to terminate the distribution agreement. Hologic has
met its minimum purchase requirements in each year of the contract. The
agreement expired in May 1996, subject to the rights of each party to pursue
an extension under conditions to be agreed upon at such time. Hologic intends
to seek an extension of the distribution agreement. There can be no assurance
that Hologic and Soredex will agree to an extension of the distribution
agreement on favorable terms, if at all.
 
CUSTOMERS
 
  Hologic's DXA customers include many pharmaceutical companies active in the
field of bone mineral metabolism, such as Eli Lilly, Merck, Pfizer, Proctor &
Gamble, Rhone-Poulenc/Rorer, Sanofi Research and SmithKline. Hologic believes
that because of their technological features, its DXA systems have been and
continue to be the most widely used bone densitometers for clinical studies
involving the emerging drug therapies for osteoporosis. Hologic has a group of
11 employees who provide data collection and quality assurance services to
such customers. Initial clinical evaluation sites for Hologic's DXA systems
included leading medical and research institutions, such as the Mayo Clinic,
the Massachusetts General Hospital and the University of California at San
Francisco in the United States; the University of Lyon and Guy's Hospital in
Europe; and Kobe University in Japan. These institutions, along with many
other leading medical institutions, continue to be users of Hologic's DXA
systems.
 
  The clinical demand for Hologic's DXA bone densitometers is growing as a
result of the increased worldwide focus on women's health problems and the
availability of new osteoporosis therapies entering the market. More than 75%
of Hologic's new sales of DXA systems have shifted to the clinical segment of
the market which includes radiologists, endocrinologists and rheumatologists.
Hologic expects a further shift in the market for bone densitometers to
primary care physicians, including gynecologists and family physicians, in
response to the development of new drug therapies for osteoporosis and the
growing awareness of osteoporosis as a treatable disease.
 
  In the first six months of fiscal 1996 and fiscal 1995, Hologic's sales to
its Japanese distributor, Toyo Medic, accounted for approximately 20% of
product sales. The loss of Toyo Medic as a customer of Hologic or an adverse
change in the relationship between Hologic and Toyo Medic could have a
material adverse affect on Hologic's business.
 
MARKETING AND SALES
 
  In the United States, Hologic sells its DXA systems primarily through its
direct sales force. As of June 30, 1996, Hologic had approximately 16
employees engaged in sales in the United States. In order to penetrate this
market more effectively, Hologic has expanded its direct marketing activities,
including additions to its sales force, and has implemented various leasing
programs, including a program with a third party leasing company to make its
QDR 4500C ACCLAIM system available to physicians on a fee-per-scan basis. To
meet the growing demand for its products, Hologic plans to enhance further its
distribution capabilities in the United States through
 
                                      58
<PAGE>
 
a combination of an expansion of its sales force and strategic alliances with
companies with established distribution channels in the various market
segments for Hologic's products. In the first quarter of Fiscal 1996, Hologic
entered into a distribution agreement with Leisegang Medical Systems. Under
this Agreement Leisegang has the exclusive right (subject to attaining certain
quotas) to represent certain Hologic products to OB/GYN and primary care
physicians in the United States.
 
  Hologic sells its DXA and Scanora systems in international markets through
independent distributors, as well as a direct sales force in France, the
Benelux countries, Spain and Portugal. As of June 30, 1996, Hologic had eight
employees engaged in sales in Europe.
 
  Hologic distributes its products in Japan through Toyo Medic, which has been
Hologic's exclusive distributor in Japan since April 1988. The agreement
requires Toyo Medic to purchase certain minimum quantities and to provide
technical and warranty support to its customers.
 
  In certain other territories outside the United States, Hologic sells its
DXA systems through independent distributors, all of whom offer technical
support. Employees of these distributors and sales representatives have
undergone product and technical training related to Hologic's products.
Hologic has increased its efforts to expand its market penetration into Latin
America, including Argentina, Brazil and Chile, and into Pacific Rim countries
other than Japan, including Australia, The Peoples Republic of China, South
Korea and Taiwan, by working with local sales representatives and distributors
or entering into strategic marketing alliances in those territories. Hologic
believes that with time, Eastern Europe may present a significant opportunity
for growth and also is seeking to expand its presence in the area.
 
  In the first six months of fiscal 1996 and in fiscal 1995, foreign sales
accounted for approximately 56% and 75% of Hologic's product sales,
respectively. Hologic believes that the relatively high level of foreign sales
reflects, in part, a more advanced regulatory status for drug therapies for
osteoporosis in certain foreign countries than in the United States.
Additionally, the large percentage of foreign sales in Japan in fiscal 1994
reflect a government initiative in Japan to provide wide-spread screening for
women's health problems such as osteoporosis and Hologic's efforts to develop
new foreign markets. Hologic's foreign sales are subject to risks generally
associated with foreign sales, including United States and foreign regulatory
approval requirements and policy changes. The relative strength of the United
States dollar in relation to foreign currencies may also adversely affect
Hologic's sales to foreign countries. Hologic also believes that its sales to
Europe may be seasonal, with reduced orders in the summer months reflecting
summer vacation schedules. International sales will also be affected by
government approval of new drug therapies, changes in local health care
policies regarding reimbursement and the strength of promotional efforts by
its distributors. See "Hologic Management's Discussion and Analysis of
Financial Condition and Results of Operations" and Note 11 of Notes to Hologic
Consolidated Financial Statements.
 
COMPETITION
 
  The bone assessment market is highly competitive and characterized by
continual change and improvement in technology, and multiple technologies that
have been or are under development. Some of the companies in this industry
have significantly greater manufacturing, marketing and financial resources
than Hologic. See "Information Regarding Hologic--Background."
 
  Five companies, Lunar, Norland Medical Systems, Aloka, Hitachi and
Osteometer, have developed DXA systems to measure bone density which compete
with Hologic's systems. Hologic believes that competition in the field of DXA
bone densitometry is based upon their price, precision, speed of measurement,
patient radiation dose, cost and ease of operation, product versatility,
product reliability and quality of service. Hologic believes that it competes
effectively with respect to these criteria. Hologic believes that its DXA
systems will also compete with other X-ray based modalities, including a
radiographic absorptiometry product developed by CompuMed Inc. which has been
licensed to Merck. Hologic's DXA systems also compete with specially-
 
                                      59
<PAGE>
 
equipped CT scanners and may compete with used and refurbished DXA systems.
See "Information Regarding Hologic--Background" for a discussion of the
technical advantages and disadvantages of these other systems.
 
  Several companies, including Igea SPA, McCue Ultrasonics, Lunar, Myriad
Ultrasound, Osteometer and Metra Biosysems, Sofratest and Vitel have developed
ultrasound systems to assess bone mineral status. Some of these companies have
had substantially more experience than Hologic in developing and marketing
their systems. Hologic believes that competition in the field of ultrasound
systems is based on price, precision, speed of measurement, cost and ease of
operation, product versatility, product reliability and quality of service.
Hologic believes that advantages of its Sahara ultrasound bone analyzer system
include the system's dry operation, simple single-button operation, and a
compact and self-contained design that does not require the use of a separate
computer. No ultrasound bone analyzer has been approved for commercial sale in
the United States. The timing of FDA clearance or approval for ultrasound bone
analyzers in the United States, developed by Hologic and others, could have a
significant impact on their respective market shares. Hologic believes that
ultrasound systems will compete with DXA systems in the diagnostic market for
initial screening of patients. However, Hologic believes that because
ultrasound systems can only measure peripheral skeletal sites and do not have
the precision of DXA systems, DXA systems will continue to be the predominant
means of monitoring bone density for patients being treated for or at high
risk of osteoporosis.
 
  Three companies have obtained FDA clearance to market biochemical marker
tests that evaluate bone turnover in a microtitre format. Ostex International
and Metra Biosystems have been cleared to market biochemical markers that
assess bone resorption. Hybritech and Metra Biosystems have been cleared to
market biochemical markers that assess bone formation. One or more of these
companies may develop point-of-care, over-the-counter or other biochemical
marker tests that would compete with the biochemical marker strip tests being
developed by Hologic and Serex. Competition in this market will be based upon
price, product reliability, diagnostic sensitivity, precision and ease of use.
There can be no assurance that Hologic and Serex will be able to compete
effectively in this market.
 
MANUFACTURING
 
  Hologic's manufacturing operations for its DXA and ultrasound systems
consist primarily of assembly, test, burn-in and quality control. Hologic
purchases a major portion of the parts and peripheral components for its
products, and manufactures certain subsystems, such as the high-voltage X-ray
power supply, from raw materials. Parts and materials are readily available
from several supply sources.
 
  Hologic is required to purchase all of its requirements for Scanora from
Soredex. Failure of Soredex to manufacture those systems on time and in
accordance with specifications would have an adverse impact on Hologic's sales
of those systems.
 
BACKLOG
 
  Backlog for Hologic's systems as of June 29, 1996 and June 24, 1995 totaled
approximately $8.4 million and $4.2 million, respectively. Backlog consists of
purchase orders for which a delivery schedule within the next twelve months
has been specified by the customer. Orders included in backlog may be canceled
or rescheduled by customers without significant penalty. Backlog as of any
particular date should not be relied upon as indicative of Hologic's net
revenues for any future period.
 
RESEARCH AND DEVELOPMENT
 
  Hologic's research and development efforts are focused on enhancing its
existing products and developing new products for the bone assessment market.
Hologic's research and development personnel also are involved in establishing
protocols, monitoring, interpreting and submitting test data to the FDA and
other regulatory agencies to obtain the requisite clearances and approvals for
its products. At June 30, 1996, Hologic had 41 persons engaged in research and
development, of whom 28 persons were engaged in the enhancement of the
 
                                      60
<PAGE>
 
DXA product line and 13 persons were engaged in the development and
enhancement of Hologic's ultrasound systems. Of these persons, 12 persons were
engaged in software development. The research and development group was
responsible for the introduction of Hologic's fourth generation QDR ACCLAIM
series of DXA bone densitometers during 1995 and the ongoing development of
Hologic's Sahara bone analyzer. During the first six months of fiscal 1995,
and during fiscal 1995, 1994 and 1993, Hologic's research and product
development expenses were approximately $3.1 million, $4.3 million, $3.4
million and $3.2 million, respectively.
 
PATENTS AND PROPRIETARY RIGHTS
 
  Hologic relies upon trade secrets and patents to protect its technology. Due
to the rapid technological change that characterizes the medical
instrumentation industry, Hologic believes that the improvement of existing
products, reliance upon trade secrets and unpatented proprietary know-how and
the development of new products are generally as important as patent
protection in establishing and maintaining a competitive advantage.
Nevertheless, Hologic has obtained patents and will continue to make efforts
to obtain patents, when available, in connection with its product development
program. Hologic has obtained 12 patents, licensed five patents and has
pending 18 patent applications in the United States relating to its DXA
technology, and has obtained three patents, licensed four patents and has
pending two patent applications in the United States relating to its
ultrasound technology. Hologic has obtained or applied for corresponding
patents and patent applications for certain of these patents and patent
applications in certain foreign countries. There can be no assurance that any
of Hologic's patent applications will be granted or that any patent or patent
application will provide significant protection for Hologic's products and
technology. Moreover, there can be no assurance that foreign intellectual
property laws will protect Hologic's intellectual property rights. In the
absence of significant patent protection, Hologic may be vulnerable to
competitors who attempt to copy Hologic's products, processes or technology.
 
  In September 1994, Serex granted Hologic an exclusive license to use Serex's
technology to manufacture, market, sell and distribute the biochemical marker
strip test being developed under a joint development agreement between Serex
and Hologic. Serex further granted Hologic the right of first negotiation with
respect to the development and distribution of new products conceived of by
Serex for application in bone metabolism. In order to maintain its exclusive
rights, Hologic is required to purchase a certain minimum number of tests or
pay Serex amounts that would have been paid had Hologic purchased the minimum
number of tests. If Hologic does not meet these minimum requirements, its
rights become nonexclusive.
 
  In June 1989, Hologic granted an exclusive worldwide license of certain of
its DXA technology to Vivid Technologies, Inc., an affiliate of S. David
Ellenbogen and Jay A. Stein, the Chief Executive Officer and Senior Vice
President of Hologic, for the sole purpose of developing a baggage inspection
and security system.
 
  Until recently, Hologic had been involved in extensive patent litigation
with Lunar, with each party claiming that the other was infringing certain
patents held by the other. This litigation was settled by agreement dated
November 22, 1995. The agreement provides for certain royalties to be paid by
each party to the other for future sales of products using certain defined
technologies. Hologic does not believe that amounts to be paid by either party
under this arrangement will be material. The agreement also provides that
neither party will engage the other party in patent litigation for a period of
ten years following the date of the agreement, regardless of the infringement
claimed and regardless of whether the technology in question currently exists
or is developed or acquired by the other party in the future. Neither party is
required to disclose to the other any of its technology during this ten year
period or otherwise. However, there can be no assurance that Lunar will not
use Hologic's technology in a manner that would materially and adversely
affect Hologic's business and results of operations.
 
THIRD PARTY REIMBURSEMENT
 
  In the United States, the Health Care Finance Administration, which
establishes guidelines for the reimbursement of health care providers treating
Medicare and Medicaid patients, provided validation for DXA bone densitometry
examinations as a clinically useful procedure by recommending the
reimbursement for DXA bone evaluations at an initial rate of $68 per scan
effective April 1994, which was increased to $124, effective
 
                                      61
<PAGE>
 
January 1995. The actual reimbursement amounts provided for DXA examinations
is determined by the individual state Medicare carriers. As of December 1995,
several of the more populous states, including California, Connecticut, New
York, New Jersey and Pennsylvania, had no or only partial reimbursement of DXA
examinations. In part as a result of HCFA's recommendations, bone density
examinations are paid for by many private third party insurers in the United
States.
 
  In several European countries, Japan and other international markets, there
has generally been an earlier adoption of reimbursement for bone densitometry
exams. Countries in which reimbursement for the use of X-ray bone
densitometers has been approved include Belgium, Brazil, Canada, Germany,
Greece, Japan, South Korea, Spain and Switzerland. In addition, in Japan,
where there is a general aversion to ionizing devices, the government has
initiated a program to subsidize purchases of ultrasound bone densitometers.
As a result, there is much greater use of ultrasound bone densitometers in
Japan than in any other country. However, DXA bone densitometers continue to
account for a substantial portion of the Japanese market.
 
REGULATION
 
  The medical devices manufactured and marketed by Hologic are subject to
regulation by the FDA and, in many instances, by foreign governments. Under
the Federal Food, Drug and Cosmetic Act (the "FDA Act"), manufacturers of
medical devices must comply with certain regulations governing the testing,
manufacturing, packaging and marketing of medical devices. Hologic's products
are also subject to the Radiation Control for Health and Safety Act,
administered by the FDA, which imposes performance standards and record
keeping, reporting, product testing and product labeling requirements for
devices using radiation, such as X-rays.
 
  The FDA generally must approve the commercial sale of new medical devices.
Commercial sales of Hologic's medical devices within the United States must be
preceded by either a premarket notification filing pursuant to Section 510(k)
of the FDA Act or the granting of a premarket approval. The 510(k)
notification filing must contain information that establishes that the device
is substantially equivalent to an existing device that has been continuously
marketed since May 28, 1976. Hologic received FDA market clearance under
510(k) for its DXA bone densitometers and expects to be eligible to seek
510(k) clearance for its biochemical marker strip test for use by physicians,
once developed.
 
  The premarket approval procedure involves a more complex and lengthy testing
and review process by the FDA than the 510(k) premarket notification procedure
and often requires at least several years to obtain. Hologic must first obtain
an investigational device exemption ("IDE") for the product to conduct
extensive clinical testing of the device to obtain the necessary clinical data
for submission to the FDA. The FDA will thereafter only grant premarket
approval if, after evaluating this clinical data, it finds that the safety and
efficacy of the product has been sufficiently demonstrated. This approval may
restrict the number of devices distributed or require additional patient
follow-up for an indefinite period of time. Hologic believes that the approval
to market its ultrasound products and its over-the-counter biochemical market
strip test, once developed, in the United States may be subject to this more
stringent FDA review process.
 
  Hologic's systems are also subject to approval by certain foreign regulatory
and safety agencies.
 
  No assurance can be given that the FDA or foreign regulatory agencies will
give the requisite approvals or clearances for any of Hologic's medical
devices under development on a timely basis, if at all. Moreover, after
clearance is given, these agencies can later withdraw the clearance or require
Hologic to change the device or its manufacturing process or labeling, to
supply additional proof of its safety and effectiveness, or to recall, repair,
replace or refund the cost of the medical device, if it is shown to be
hazardous or defective. The process of obtaining clearance to market products
is costly and time-consuming and can delay the marketing and sale of Hologic's
products.
 
  As a manufacturer of medical devices, Hologic is subject to certain other
FDA regulations and Hologic's manufacturing processes and facilities are
subject to continuing review by the FDA. Most states and certain other
 
                                      62
<PAGE>
 
foreign countries monitor and require licensing of X-ray devices. Federal,
state and foreign regulations regarding the manufacture and sale of medical
devices are subject to future change. Hologic cannot predict what impact, if
any, such changes might have on its business.
 
EMPLOYEES
 
  As of June 30, 1996, Hologic had 241 full-time employees, including 75 in
manufacturing operations, 41 in research and development, 87 in marketing,
sales and support services, 27 in finance and administration and 11 in medical
data management. None of Hologic's employees are represented by a union.
Hologic considers its employee relations to be good.
 
PROPERTIES
 
  Hologic leases a 83,500 square foot building located in Waltham,
Massachusetts under a lease which expires in 2002. Hologic also leases an
additional 3,100 square feet of nearby office space under a tenancy at will.
Hologic believes that its facilities will be adequate for its needs for the
foreseeable future. Hologic also maintains sales and service offices in
France, Belgium and Spain. Hologic believes that it has adequate space for its
anticipated needs and that suitable additional space will be available at
commercially reasonable prices as needed.
 
LITIGATION
 
  On November 22, 1995, Hologic and Lunar entered into a settlement agreement
relating to litigation involving allegations of each party against the other
of patent infringement. See "Information Regarding Hologic--Patents and
Proprietary Rights."
 
  Until recently, Hologic had been involved in litigation brought in January
1995 by B.V. Optische Industrie de Oude Delft and two subsidiaries ("Oldelft")
claiming damages relating to a prior patent dispute. On December 14, 1995, the
United States District Court for the Southern District of New York granted
Hologic's Motion to Dismiss and dismissed all claims against Hologic. In
January 1996, Oldelft filed a motion for reconsideration of the dismissal and
amended its complaint. In April 1996, the Court denied Oldelft its motion for
reconsideration of the dismissal, and in May 1996 Hologic and Oldelft settled
this matter.

    HOLOGIC MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
                             RESULTS OF OPERATIONS
 
OVERVIEW
 
  Since inception, Hologic has experienced generally increasing annual sales
as interest in bone diseases, such as osteoporosis, has grown, as new drug
therapies have become available in the United States and other countries to
treat these diseases and as the use of DXA systems to measure bone density has
become more widespread. Hologic's revenues increased 75% to $43.4 million in
1995 from $24.8 million in 1993. During 1995, Hologic's net income was
adversely impacted by litigation costs of $2.5 million, or $0.21 per share,
incurred in connection with Hologic's dispute with Lunar, which was settled in
November 1995, and, to a lesser extent, its dispute with Oldelft which was
dismissed in December 1995. In fiscal 1993, Hologic's sales dropped slightly
from fiscal 1992 as a result of certain recessionary economic trends in Europe
and a significant reduction of United States sales due to uncertainty over the
direction of proposed healthcare reform. In fiscal 1994 and 1995, the economic
climate in Europe steadily improved and the uncertainty over United States
government reform of the healthcare system abated. In addition, Hologic was
successful in its efforts to develop new international markets in Latin
America and the Pacific Rim.
 
  Hologic commenced operations in April 1986 and was primarily engaged in
product development through the end of fiscal 1987. Hologic shipped the first
QDR 1000 for clinical testing in June 1987 and began commercial shipments of
the system in October 1987 upon receipt of FDA marketing clearance. Hologic
introduced a bone densitometer capable of assessing the bone density of the
entire body in 1989, introduced the first bone densitometer capable of taking
supine lateral measurements of the spine in 1991, and introduced its fourth
generation clinically-oriented QDR 4500 ACCLAIM series of bone densitometers
at the annual meeting of the Radiological Society of North America in November
1994. Hologic's shipments of its high-end QDR 4500A ACCLAIM began in January
1995 and of its entire ACCLAIM product line began in the third quarter of
fiscal 1995. In the first six months of fiscal 1996, ACCLAIM sales represented
approximately 90% of Hologic's total DXA sales. Hologic achieved a slightly
higher gross margin on this product line because of higher selling prices and
lower overall manufacturing costs than the older DXA line.
 
  Hologic believes that the two major drivers of the growth in demand for its
bone densitometers are (i) the availability of new and effective drug
therapies to treat and prevent bone diseases, including osteoporosis, and (ii)
the availability of reimbursement to healthcare providers for bone density
measurements of patients. On September 29, 1995, the FDA cleared for marketing
Merck's new bisphosphonate, Fosamax, for treatment of established osteoporosis
in post-menopausal women. The Health Care Finance Administration, the agency
which administers Medicare, increased the recommended reimbursement rate for
DXA tests to a national average of $124, effective January 1, 1995, from $68,
the original recommended reimbursement rate which went into effect in April
1994.
 
RECENT DEVELOPMENTS
 
  For the three and nine months ended June 29, 1996, Hologic reported revenues
of $22,829,028 and $56,349,729, respectively, as compared with revenues of
$11,301,320 and $30,531,294 for the same periods ended June 24, 1995. Hologic
also reported net income for the three and nine months ended June 29, 1996 of
$3,940,030, or $.32 per share, and $8,271,037, or $.76 per share,
respectively, as compared with net income of $487,668, or $.06 per share, and
$1,284,998, or $.15 per share, for the same periods ended June 24, 1995.

</TABLE>
 
SIX MONTHS ENDED MARCH 30, 1996 COMPARED TO SIX MONTHS ENDED MARCH 25, 1995
 
  Revenues. Total revenues for the first six months fiscal 1996 increased 74%
to $33,520,701 from $19,229,974 for the first six months of fiscal 1995. This
increase was primarily due to the increase in the total number of DXA bone
densitometer product shipments in both Hologic's domestic and international
markets, particularly in the United States where product sales for the first
six months of fiscal 1996 increased 600% over the prior year. There was also a
shift in product sales mix to Hologic's new line of bone densitometers, the
ACCLAIM series, which Hologic began shipping in January 1995. The new ACCLAIM
products have higher average selling prices than the comparable DXA bone
densitometers which they replace. For the second quarter of fiscal 1996, sales
of the ACCLAIM product accounted for over 93% of product sales. Other revenues
also increased due to increases in revenue relating to medical data management
services provided to pharmaceutical companies to assist in the collection and
monitoring of clinical trial data.
 
  In the first six months of fiscal 1996, approximately 44% of product sales
were generated in the United States, 27% in Asia, 23% in Europe, and 6% in
other international markets. In the first six months of fiscal 1995,
approximately 12% of product sales were generated in the United States, 41% in
Asia, 40% in Europe and 7% in other international markets.
 
  Hologic believes that the two major drivers of the growth in demand for its
bone densitometers are (i) the availability of new and effective drug
therapies to treat and prevent bone diseases, including osteoporosis, and (ii)
the availability of reimbursement to healthcare providers for bone density
measurements of patients. On September 29, 1995, the FDA cleared for marketing
Merck's new bisphosphonate, Fosamax, for treatment of established osteoporosis
in post-menopausal women. The Health Care Finance Administration, the agency
which administers Medicare, increased the recommended reimbursement rate for
DXA tests to a national average of
 
                                      65
<PAGE>
 
$124, effective January 1, 1995, from $68, the original recommended
reimbursement rate which went into effect in April 1994.
 
  Costs and Expenses. The cost of product sales decreased as a percentage of
product sales to 47% in the first six months of fiscal 1996 from 56% in the
first six months of fiscal 1995. In the first six months of fiscal 1996, these
costs decreased as a percentage of product sales primarily due to increasing
shipments of Hologic's new family of DXA bone densitometers, the ACCLAIM
series, a volume increase in the number of DXA systems sold resulting in
certain manufacturing efficiencies, and an increase in sales by Hologic's
direct sales force (primarily in the United States) which results in higher
selling prices. Hologic began selling the ACCLAIM product in the second
quarter of fiscal 1995 and has recognized higher gross margins than on the
older DXA product line from higher average selling prices and lower labor and
overhead-related manufacturing costs.
 
  Research and development expenses increased 48% to $3,076,899 (9% of total
revenues) in the first six months of fiscal 1996 from $2,076,566 (11% of total
revenues) for the first six months of fiscal 1995. The increase in research
and development expenses in the fiscal 1996 period was primarily due to the
addition of engineering personnel and outside consultants working on the
development of new products. As a percentage of total revenues, research and
development expenses declined in the first six months of fiscal 1996,
reflecting increased revenues during that period.
 
  Selling and marketing expenses increased 63% to $5,758,126 (18% of product
sales) in the first six months of 1996 from $3,534,468 (19% of product sales)
in the first six months of fiscal 1995. The increase in selling and marketing
expenses in the fiscal 1996 period was primarily due to an increase in sales
personnel and related expenses, marketing and promotional costs incurred in
connection with the introduction of the ACCLAIM series and increased sales
commissions based on the higher sales volume. In addition, Hologic incurred
additional costs in connection with its strategic alliances for the
development of new products and the distribution of products through new sales
channels.
 
  General and administrative expenses increased 59% to $3,250,551 (10% of
total revenues) in the first six months of fiscal 1996 from $2,039,807 (11% of
total revenues) in the first six months of fiscal 1995. The increase in
general and administrative expenses in the fiscal 1996 period were primarily
due to increased headcount and other compensation-related expenditures, and an
increase in accounts receivable reserves, which reflects the increase in
accounts receivable.
 
  Litigation expenses incurred in the first six months of fiscal 1996 and in
fiscal 1995 were in connection with Hologic's disputes with Lunar and Oldelft.
Legal expenses in connection with the patent litigation with Lunar began in
October 1994 and represent a substantial portion of the total litigation
expenses. In November 1995, a definitive agreement that provides for the
cross-licensing of certain patent rights and a non-assertion agreement for all
patents involving DXA and ultrasound technologies for a period of ten years
was reached by Hologic and Lunar. The complaint brought by Oldelft against
Hologic was dismissed in December 1995. In January 1996, Oldelft filed a
motion for reconsideration of the dismissal and amended its complaint. In
April 1996, the Court denied Oldelft its motion for reconsideration of the
dismissal, and in May 1996 Hologic and Oldelft settled this matter.
 
  Interest Income. Interest income increased to $749,245 in the first six
months of fiscal 1996 from $282,571 in the comparable period in fiscal 1995 as
Hologic earned a higher rate of return on a higher investment base than in the
prior year. In January 1996, Hologic received proceeds of approximately
$49,300,000 from a public sale of Common Stock which increased the investment
base. Hologic has invested these proceeds in investment grade corporate and
government securities. In fiscal 1996, Hologic has also increased the number
of long-term receivables to Latin American customers which generates
additional interest income.
 
  Other Expense. In the first six months of fiscal 1996, Hologic incurred
other expenses of $123,763. These expenses were slightly less than other
expenses incurred in the comparable period of fiscal 1995 and were primarily
attributable to the interest costs on the line of credit established by
Hologic in the third quarter of fiscal
 
                                      66
<PAGE>
 
1994 and, to a lesser extent, foreign currency exchange losses arising from
Hologic's U.S. dollar denominated sales transactions to its European
subsidiaries. Hologic's European subsidiaries utilize the line of credit to
borrow funds in their local currencies to pay for all intercompany sales,
thereby reducing the foreign currency exposure on those transactions. To the
extent that foreign currency exchange rates fluctuate in the future, Hologic
may be exposed to continued financial risk. Although Hologic has established a
borrowing line denominated in the two foreign currencies (the French Franc and
the Belgian Franc) in which the subsidiaries currently conduct business to
minimize this risk, there can be no assurance that Hologic will be successful
or can fully hedge its foreign currency exposure.
 
  Provision for Income Taxes. Hologic's effective tax rate for the first six
months of fiscal 1996 was 28.4%. Hologic's effective tax rate is lower than
the statutory tax rates due primarily to the utilization of tax credits, the
utilization of net operating losses in foreign jurisdictions and tax benefits
associated with Hologic's foreign sales corporation. Hologic's effective tax
rate may increase for the remainder of fiscal 1996 depending on the mix of
U.S. versus international income and the availability of tax credits.
 
FISCAL YEARS ENDED SEPTEMBER 30, 1995, SEPTEMBER 24, 1994 AND SEPTEMBER 25,
1993
 
  Revenues. Total revenues were $43.4 million in fiscal 1995, $38.5 million in
fiscal 1994 and $24.8 million in fiscal 1993. The increase in total revenues
of 13% in fiscal 1995 compared to fiscal 1994 was primarily due to the
increase in the total number of DXA product shipments in both Hologic's
domestic and international markets, particularly to Europe where product sales
increased 30% over the prior year. During fiscal 1995, there was also a shift
in product sales mix to Hologic's new line of bone densitometers, the ACCLAIM
series, which Hologic began shipping in January 1995. The new ACCLAIM products
have higher average selling prices than the comparable DXA bone densitometers
which they replace. For the current year, sales of the ACCLAIM product
accounted for over 42% of product sales. The increase in total revenues in
fiscal 1994 compared to 1993 was primarily due to the increase in the total
number of DXA product shipments in both Hologic's domestic and international
markets, particularly Japan where Hologic's distributor accounted for 28% of
product sales in fiscal 1994. During fiscal 1994, there was also a shift in
product sales mix from fiscal 1993, with an increased percentage of sales
being derived from the higher-priced QDR 2000plus and QDR 2000 systems, and an
increase in sales of two X-ray products which Hologic began to sell as a
distributor, primarily in Europe.
 
  Other revenues consist of royalty revenues from Hologic's licensing of its
technology to a related party and revenue relating to medical data management
services provided to pharmaceutical companies to assist in the collection and
monitoring of clinical trial data. In fiscal 1995, other revenue increased 59%
to $2.3 million from $1.4 million in fiscal 1994, primarily due to an increase
in revenue for medical data management services. In fiscal 1994, other revenue
increased 101% from $710,000 in fiscal 1993 primarily due to an increase in
royalty revenues and, to a lesser extent, an increase in revenue relating to
medical data management services.
 
  In fiscal 1995, approximately 37% of product sales were generated in Europe,
29% in Asia, 25% in the United States and 9% in other international markets.
In fiscal 1994, approximately 38% of product sales were generated in Asia, 31%
in Europe, 26% in the United States and 5% in other international markets. In
fiscal 1993, approximately 51% of product sales were generated in Europe, 26%
in the United States, 17% in Asia and 6% in other international markets.
Hologic expects that foreign sales in the current fiscal year will continue to
account for a substantial portion of product sales.
 
  Costs and Expenses. The cost of product sales decreased as a percentage of
product sales to 54% in fiscal 1995 from 56% in fiscal 1994 and from 57% in
fiscal 1993. In fiscal 1995, these costs decreased as a percentage of product
sales primarily due to Hologic initiating shipments of its new family of DXA
bone densitometers, the ACCLAIM series, and a volume increase in the number of
DXA systems sold resulting in certain manufacturing efficiencies. Hologic
began selling the ACCLAIM product in the second quarter of fiscal 1995 and has
recognized higher gross margins than on the older DXA product line from higher
average selling prices and lower labor and overhead-related manufacturing
costs. In fiscal 1994, the cost of product sales decreased as a
 
                                      67
<PAGE>
 
percentage of product sales primarily due to the volume increase in the number
of DXA systems sold and the associated manufacturing efficiencies. These gross
margin improvements were offset somewhat by increased sales of X-ray systems,
which are distributed but not manufactured by Hologic in Europe, resulting in
an overall gross margin percentage that is less than what is earned on the DXA
product line.
 
  Research and development expenses increased 25% to $4.3 million (10% of
total revenues) in fiscal 1995 from $3.4 million (9% of total revenues) in
fiscal 1994 primarily due to the addition of engineering personnel and outside
consultants working on the development of new products and the funding of
Serex to develop a biochemical marker strip test. In fiscal 1994, research and
development expenses increased from $3.2 million (13% of total revenues) in
fiscal 1993 primarily due to the addition of engineering personnel working on
the development of new products and due to higher prototype material costs
associated with Hologic's new fourth-generation QDR 4500 ACCLAIM bone
densitometers.
 
  Selling and marketing expenses increased 33% to $7.8 million (19% of product
sales) in fiscal 1995 from $5.9 million (16% of product sales) in fiscal 1994.
The increase in fiscal 1995 expenses was primarily due to an increase in sales
personnel and related expenses, marketing and promotional costs incurred in
connection with the introduction of the QDR 4500 ACCLAIM product and increased
sales commissions based on the higher sales volume. In fiscal 1994, selling
and marketing expenses increased 8% from $5.5 million (23% of product sales)
in fiscal 1993. The increase in fiscal 1994 from 1993 was primarily due to
increased sales commissions based on the higher sales volume, especially in
North America and Latin America where Hologic sells directly to end-user
customers. In addition, Hologic incurred additional costs in connection with
its initiation of a formal new business development effort, which has resulted
in Hologic's recent product acquisitions and strategic alliances. The decrease
in expenses as a percentage of product sales in fiscal 1994 was due to the
significant increase in sales volume to distributors which generally do not
receive commissions.
 
  General and administrative expenses increased to $4.5 million (10% of total
revenues) in fiscal 1995 from $4.2 million (11% of total revenues) in fiscal
1994 and $3.5 million (14% of total revenues) in fiscal 1993. The increase in
fiscal 1995 was primarily due to increased head count and other compensation-
related expenditures. The increase in fiscal 1994 when compared to fiscal 1993
was primarily due to increases in accounts receivable reserves, which reflects
the increase in accounts receivable, and an increase in employee incentive
programs. These increases were offset in part by a decrease of general and
administrative expenses in Europe as part of the reorganization begun in the
fourth quarter of fiscal 1993.
 
  Litigation expenses incurred in fiscal 1995 were in connection with
Hologic's disputes with Lunar and Oldelft. Legal expenses in connection with
the patent litigation with Lunar began in October 1994 and represent a
substantial portion of the total litigation expenses. In November 1995, a
definitive agreement that provides for the cross-licensing of certain patent
rights involving DXA and ultrasound technologies for a period of ten years was
reached by Hologic and Lunar. The complaint brought by Oldelft against Hologic
was dismissed in December 1995.
 
  In the fourth quarter of fiscal 1993, Hologic recorded a restructuring
charge of $900,000. This nonrecurring charge covered the reorganization of its
European operations, including consolidation of the distribution and
administrative infrastructure, asset write-offs including receivables and
inventory, and a reduction of its European workforce. The charges from this
restructuring were a result of the weak European economy and Hologic's desire
to reallocate its resources to expanding territories with greater growth
potential. At the end of fiscal 1994, Hologic's reorganization was complete
and all restructuring charges had been incurred.
 
  Interest Income. Interest income increased to $610,000 in fiscal 1995 from
$320,000 in fiscal 1994 as Hologic earned a higher rate of return on a
slightly higher investment base than in the prior year and increased the
number of long-term receivables to Latin American customers. In fiscal 1994,
interest income increased from $300,000 in fiscal 1993 as Hologic earned a
slightly higher rate of return on a slightly lower investment base than in the
preceding year.
 
 
                                      68
<PAGE>
 
  Other Expense. In fiscal 1995 and 1994, Hologic incurred other expenses of
$270,000 and $80,000, respectively. These expenses were primarily attributable
to the interest costs on a line of credit established by Hologic in the third
quarter of fiscal 1994 for use by Hologic's European subsidiaries to borrow
funds in their local currencies to pay for all intercompany sales, thereby
reducing the foreign currency exposure on those transactions.
 
  In fiscal 1993, Hologic recognized other expenses of $440,000 which
primarily represented foreign currency exchange losses, net of hedge
transactions, arising from Hologic's United States dollar-denominated sales to
its three European subsidiaries. Approximately one-half of the losses for the
year were incurred in the first quarter, prior to the implementation of
Hologic's program to purchase foreign currency forward contracts to hedge its
foreign currency exposure. In 1993, the United States dollar strengthened
significantly against the three foreign currencies (the French franc, the
Belgian franc and the Spanish peseta) in which the subsidiaries conducted
business causing Hologic to recognize a transaction loss.
 
  To the extent that foreign currency exchange rates fluctuate in the future,
Hologic may be exposed to continued financial risk. Although Hologic has
established a borrowing line denominated in the two foreign currencies (the
French franc and the Belgian franc) in which the subsidiaries currently
conduct business to minimize this risk, there can be no assurance that Hologic
will be successful or can fully hedge its outstanding exposure.
 
  Provision for Income Taxes. Hologic's effective tax rate was 25.8% in fiscal
1995 and 30.8% in fiscal 1994. In fiscal 1993, Hologic had a benefit for
income taxes as a result of that year's loss. Hologic's effective tax rate is
lower than the statutory tax rates due primarily to the utilization of tax
credits, the utilization of net operating losses in foreign jurisdictions and
tax benefits associated with Hologic's foreign sales corporation.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  Hologic has funded its operations primarily through cash flows from
operations and the issuance of securities.
 
  At March 30, 1996, Hologic's working capital was $74,559,246. At such date,
Hologic had $62,016,180 in cash, cash equivalents and short-term investments.
The cash, cash equivalents and investments balance increased approximately
$52,076,000 from September 30, 1995 primarily due to the net proceeds of
approximately $49,300,000 from the public offering of common stock in the
second quarter. In addition, the cash and investments balance increased
approximately $2,776,000 primarily due to the proceeds and tax benefits from
the exercise of stock options and an increase in Hologic's current
liabilities, which were partially offset by an increase in accounts
receivable. The increase in current liabilities and accounts receivable
reflects Hologic's introduction of its new ACCLAIM family of bone
densitometers and the increase in sales activity. At March 30, 1996, one
customer had accounts receivable outstanding of approximately $3,355,000,
which were current within their payment terms. Hologic finances certain sales
to Latin America over a two to three year time frame. At March 30, 1996,
Hologic had long-term accounts receivable outstanding of approximately
$942,000 relating to these sales, which were included in other assets. In the
first six months of fiscal 1996, Hologic purchased approximately $686,000 of
property and equipment, primarily computers and other equipment associated
with the hiring of additional personnel.
 
  Hologic and FluoroScan estimate that they will incur direct transaction
costs of approximately $1.8 million associated with the Merger. These
transactions costs will be expensed in the period incurred under the pooling-
of-interests method of accounting for business combinations. As a result, the
earnings of the combined entity will be adversely affected. This amount is a
preliminary estimate only and therefore subject to change. There can be no
assurance that Hologic and FluoroScan will not incur additional charges to
reflect costs associated with the Merger.
 
  Hologic does not currently have any significant capital commitments and
believes that existing sources of liquidity, including the anticipated net
proceeds of the proposed offering, funds expected to be generated from
operations and a $3.0 million credit line for use by its European
subsidiaries, will provide adequate cash to fund Hologic's anticipated working
capital and other cash needs for the foreseeable future.

                       INFORMATION REGARDING FLUOROSCAN
 
GENERAL
 
  FluoroScan manufactures and distributes the FluoroScan Imaging System (the
"FluoroScan System"), a low intensity, real time X-ray imaging device which
provides high resolution images at radiation levels and at a cost well below
those of conventional X-ray and fluoroscopic equipment. The FluoroScan System
technology is based on a micro channel plate image intensifier commonly known
as a "night vision" intensifier. This technology permits the FluoroScan System
to produce high resolution images using only a small amount of radiation that
is converted to visible light and amplified approximately 50,000 times. In
this manner, the FluoroScan System provides both still X-ray pictures and real
time images similar to those produced by a video camera, permitting users to
view, for example, the movement of bones in a flexing hand as well as the
placement of bones in a still extremity or the circuitry inside a computer.
 
  FluoroScan believes it has the largest installed base of mini C-arms in the
medical device market. FluoroScan currently sells different models of the
FluoroScan System and certain related products to various customers including
major university hospitals, clinics and orthopedic surgeons.
 
BACKGROUND
 
  FluoroScan was incorporated in Delaware in 1984 under the name HealthMate,
Inc. ("HealthMate"), as the successor to HealthMate of Illinois, Inc. and
Lixiscope of America, Inc., which were incorporated in Illinois in 1982 and
1981, respectively. In 1984 and 1985, HealthMate entered into two exclusive
license agreements with NASA for certain patents and developed the underlying
technology into the current FluoroScan Imaging System. See "Information
Regarding FluoroScan--Licenses and Other Proprietary Information," below.
 
  HealthMate completed a $3.5 million initial public offering in 1985.
Offering proceeds were used to market the FluoroScan System and for continued
research and development of the exclusively licensed technology. Mr. Grossman,
one of HealthMate's founders, left HealthMate in 1986 due to a disagreement
with certain members of the Board of Directors as to the future direction of
FluoroScan and resigned as a director in 1987. Mr. Issette, who had joined
HealthMate in 1984 as a director, also resigned in 1987. HealthMate's business
experienced a significant downturn following Mr. Grossman's departure. In
March 1989, Messrs. Grossman and Issette returned to HealthMate and caused
HealthMate to file a Chapter 11 petition for protection under the United
States Bankruptcy Code. Messrs. Grossman and Issette also reorganized
HealthMate into a privately-held company, after making equity contributions of
$100,000 each in connection with the reorganization plan. The reorganization
plan was confirmed in June 1991 and closed in September 1991. In 1991,
HealthMate changed its name to "FluoroScan Imaging Systems, Inc." and
FluoroScan made the final payment in respect of its remaining obligations to
creditors in April 1994.
 
  In July 1994, FluoroScan completed a public offering of FluoroScan Units
which netted FluoroScan $3.087 million. Each Unit consisted of one share of
FluoroScan Common Stock and one FluoroScan Redeemable Common Stock Warrant. In
August 1994 FluoroScan received an additional $913,000 in proceeds from the
exercise of an over allotment option granted to the underwriter.
 
  In November 1995, FluoroScan International, Inc. was incorporated as a
wholly-owned subsidiary of FluoroScan.
 
THE FLUOROSCAN TECHNOLOGY
 
  The basis of the FluoroScan System technology is a second generation micro
channel plate image intensifier commonly referred to as a "night vision"
intensifier. This technology permits the FluoroScan System to produce high
resolution readily viewable images by using a small amount of radiation,
converting it to visible light and amplifying it approximately 50,000 times.
The same night vision intensifier, as used by the military, allows clear views
of a battlefield at night by amplifying small amounts of ambient light.
 
                                      70
<PAGE>
 
  The FluoroScan System technology offers several advantages over existing
real time X-ray imaging devices (also known as C-arms, image intensifiers or
fluoroscopy equipment). These advantages include:
 
    (1) Substantial reduction of radiation to the patient and of scatter
  radiation to the surgeon and other operating room personnel. FluoroScan
  estimates that the FluoroScan System reduces radiation exposure by
  approximately 90% as compared to a conventional C-arm imaging device, based
  on testing conducted by independent health physicists. Because of this
  reduction, FluoroScan has received waivers from the legal requirement
  imposed by many states that persons in a room with an operating X-ray
  device must wear lead aprons. FluoroScan is not aware of any other X-ray
  device which has received such waivers.
 
    (2) The FluoroScan System costs approximately one-third of the cost of a
  conventional C-arm, although the relevant health care codes for
  reimbursement are the same for the FluoroScan System and conventional
  fluoroscopy equipment. Thus, users in the health care field are able to
  recover the cost of purchasing the FluoroScan System more quickly and with
  fewer procedures.
 
    (3) The FluoroScan System is mobile, does not require lead-lined rooms
  and can often be operated without a radiology technician. Users of the
  FluoroScan System can move the unit easily from room to room, thereby
  saving space and money.
 
    (4) The FluoroScan System does not require the regular service and tube
  replacement required by conventional C-arms. The FluoroScan System operates
  with micro amperage current instead of the milli amperage current used by
  conventional equipment, and a typical setting ranging from 25 to 99
  microamps rather than the typical 3,000 microamps (three milliamps) for
  conventional equipment. For these reasons, the FluoroScan System can be
  operated continuously without overheating, while conventional equipment can
  require frequent and lengthy cooling-off periods or internal cooling
  devices, and FluoroScan's X-ray tube has a longer life than conventional
  equipment. In addition, the X-ray tube replacement cost for a FluoroScan
  System is approximately $5,000, which is substantially less than the cost
  to replace an X-ray tube in a conventional C-arm.
 
THE MARKET
 
 Medical Applications
 
  Approximately 98% of FluoroScan's sales are to healthcare customers. The
FluoroScan System is used in the healthcare field primarily for extremity
imaging to assist with various minimally invasive surgical procedures and to
detect fractures and foreign objects. Historically, FluoroScan has sold the
FluoroScan system primarily to hospitals and ambulatory surgery centers for
use by orthopedic surgeons in the operating room, and to a lesser extent, for
other medical uses.
 
  FluoroScan believes that certain trends in the healthcare industry will
enable the company to broaden its FluoroScan sales from these hospitals and
surgery centers to private orthopedic and podiatric physician groups. Some of
these trends include:
 
  .  the emergence of technology that enables minimally invasive procedures
     and therapies;
 
  .  the increase in the number of office-based procedures and examinations
     as a result of efforts to contain healthcare costs; and
 
  .  the development of new treatments and pharmaceuticals such as synthetic
     bone materials that are facilited by the use of a mini C-arm to perform
     these procedures.
 
 Other Applications
 
  FluoroScan has also sold the FluoroScan System for industrial use. It is
used in various industries for quality control, inspection of parts and other
imaging requirements.

THE FLUOROSCAN MODELS AND RELATED PRODUCTS
 
  FluoroScan currently sells different models of FluoroScan System units,
accessory supply items, service and extended service contracts.
 
  FluoroScan III. The FluoroScan III imaging system was introduced in the
fourth quarter of 1995. The FluoroScan III typically has a four- or five-inch
field-of-view and is targeted primarily at orthopedic surgeons, operating
rooms, emergency rooms and ambulatory surgery centers. The new system replaced
FluoroScan I (the first generation model FluoroScan System) and has a number
of technical enhancements. FluoroScan III has dual video channels that allow a
surgeon to display different views of the anatomy for side-by-side comparison.
The unit also features four image buffer memories for instant recall of
previous images. The unit also provides for permanent storage of up to 4,000
full resolution digital images.
 
  The unit stands approximately four feet high, weighs about 240 pounds and
can be plugged into any standard outlet. It rests on a portable, wheeled base
cabinet, and all vital functions are computer controlled. Images can be viewed
on the monitor or, through the addition of options, printed on thermal paper
or stored on video tape or computer diskette.
 
  FluoroScan II. FluoroScan has introduced the FluoroScan II to veterinarians
and has exhibited a prototype of the FluoroScan II to orthopedic surgeons for
use in their offices and to other medical and veterinary offices, podiatrists
and sports medicine physicians as well as for use by the military and various
industries. FluoroScan believes that the target audience for the three-inch
field-of-view FluoroScan II consists of users seeking a lower cost or more
mobile unit than the FluoroScan III. FluoroScan manufactures two versions of
the FluoroScan II for the veterinary and medical markets. The veterinary
version differs from the medical version of the FluoroScan II in that it is
contained in a portable carrying case with a removable C-arm, which may be
hand held. FluoroScan began sales of the veterinary version of this item in
the third quarter 1995. FluoroScan expects to begin sales of the medical
version of the FluoroScan II in the first quarter of 1997.
 
  Future Models. FluoroScan is now developing another model which will permit
imaging of larger areas, such as adult hips and spines. These applications are
currently being served mainly with conventional high-radiation imaging
products. See "Information Regarding FluoroScan--Research and Development,"
below.
 
OTHER PRODUCTS AND SERVICES
 
  In addition to FluoroScan System models, FluoroScan also sells accessory
items and options such as custom designed sterile drapes, thermal printer
paper, video cassette recorders, and video printers. The drapes are required
in the operating room for each procedure performed in order to maintain a
sterile field. In addition, thermal printer paper is sold for use with a video
printer. This printer permits users to produce a hard copy picture of the
FluoroScan System image. Sales of accessory items and options have increased
with increased FluoroScan System sales, and FluoroScan expects this trend to
continue. FluoroScan also derives revenues from service sales and the sale of
extended maintenance agreements. Sales of accessories, options and service
currently account for approximately 7% of sales annually.
 
SALES AND MARKETING
 
  FluoroScan markets and sells the FluoroScan System and related products in
the United States health care market through its employees and a national
network of independent sales representatives and sales representative
organizations. Products are marketed and sold to non-health care customers in
the United States through one independent industrial sales representative. All
of these sales representatives are paid, on a commission basis, after the
customer has paid for the purchased FluoroScan System unit. Sales
representatives generally earn commissions equal to 20% of net sales. All
medical sales representatives have been granted exclusive territories and are
required to meet specified sales quotas.
 
  Domestic marketing efforts are centered on trade show appearances, direct
mailing of promotional videos, product brochures, and print advertising in
trade journals. FluoroScan representatives currently attend in excess
 
                                      72
<PAGE>
 
of 100 trade shows and laboratory exhibitions per year and FluoroScan
currently mails in excess of 200 videos per month. FluoroScan plans to expand
its efforts in print advertising, direct mailings, and trade show appearances.
 
  To promote expansion of its international business, FluoroScan established a
wholly-owned subsidiary in November 1995, FluoroScan International Inc., which
operates a branch in Paris, France. FluoroScan markets, sells and services its
products internationally through independent distributors who purchase units
from FluoroScan for resale to their customers. There are currently
international distributors selling FluoroScan's products in Australia,
Austria, Belgium, Canada, Finland, France, Holland, Germany, Hong Kong,
Iceland, Italy, Korea, Luxembourg, Norway, Sweden, Switzerland and the United
Kingdom. In 1995, international sales comprised approximately 8% of
FluoroScan's total annual sales. Management expects such sales to continue to
grow as the FluoroScan System receives certain variances and allowances to
sell in foreign countries and because of its ongoing establishment of foreign
distribution networks.
 
CORPORATE COLLABORATIONS
 
 Norian Corporation. On June 12, 1995, FluoroScan announced that it had
entered into a worldwide exclusive partnership agreement with Norian
Corporation ("Norian"), based in Cupertino, CA. The agreement provides for
FluoroScan to provide imaging equipment for seminars introducing Norian's
Skeletal Repair System(TM) ("SRS") to orthopedic surgeons.
 
  Norian is in clinical trials in the U.S. and Europe for SRS. SRS is a
material that is injected into a fracture and has been shown to hold the bones
in position while providing the raw materials to help the body repair itself
more rapidly. Since SRS requires extensive imaging from the initial injection
through the healing process, FluoroScan believes that FDA approval and market
acceptance of SRS could provide long-term benefits for FluoroScan. There can
be no assurance that SRS will receive FDA approval, or if approved will gain
wide market acceptance or enhance sales of FluoroScan's products.
 
 Picker International. On June 4, 1996, FluoroScan announced that it had
signed a renewable one year agreement with Picker International ("Picker") to
provide on-site, same day nationwide servicing of FluoroScan equipment to
FluoroScan customers in the United States. Picker also serves as FluoroScan's
distributor in Canada.
 
MANUFACTURING AND SUPPLIERS
 
  FluoroScan manufactures all FluoroScan System models and related products at
its manufacturing facility in Northbrook, Illinois. Current manufacturing
capacity permits the production of approximately 30 units per month.
Generally, units for use in the health care field are manufactured without a
prior order, while units for use in industrial applications are custom made to
the customer's specifications.
 
  FluoroScan manufactures all of the FluoroScan System's components from raw
materials, with the exception of the X-ray tube, fiberoptic taper, night
vision intensifier, video monitor and camera. All of the raw materials and
most of the purchased components used in manufacturing FluoroScan's products
are readily available from numerous sources. Several key components require
high technology and are manufactured by only one or a small number of
suppliers, including Incom Inc., Kevex X-Ray, Inc., Litton Inc., and Schott
Fiber Optics Inc.
 
  Although FluoroScan uses materials in its manufacturing process that may be
subject to federal, state and/or local environmental laws, the costs and
effects of compliance with these laws have not had a material effect on
FluoroScan's financial condition or results of operations during any of the
past three years.

COMPETITION
 
  FluoroScan is the exclusive licensee for the FluoroScan System technology in
the United States. FluoroScan's known direct competitor in the manufacture of
the mini C-arm imaging systems is Xi Tec, which has manufactured a comparable
system pursuant to a sublicense from FluoroScan. Other direct competitors
include OEC Medical and Lunar, each of which manufactures a small conventional
C-arm imaging system that does not use FluoroScan's patented technology and
Lixi, which manufactures an X-ray tube version, Lixiscope, only for the
industrial marketplace. FluoroScan believes that Lixi's products have
infringed on one of the three patents originally licensed by FluoroScan from
NASA and has so notified NASA. This patent expires in July 1997, and as a
consequence, some of FluoroScan's competitors may then attempt to utilize this
technology. See "Information Regarding FluoroScan--Licenses and Other
Proprietary Information."
 
  Although it has no other direct competition, FluoroScan competes indirectly
with manufacturers of conventional C-arms, including Siemens A.G., General
Electric Company, Fischer Imaging Corporation, OEC Medical Inc., Philips N.V.
and Picker. These competitors have substantially greater financial and
marketing resources than FluoroScan.
 
  Both direct and indirect competition is based largely on price, quality,
service and production capabilities. FluoroScan believes it is well positioned
to compete effectively due to the FluoroScan System's significantly lower
levels of radiation and its cost, mobility, quality and durability. See
"Information Regarding FluoroScan--The FluoroScan Models and Related
Products."
 
LICENSES AND OTHER PROPRIETARY INFORMATION
 
  FluoroScan has two license agreements with the United States government as
represented by NASA that are exclusive within the United States. The first
agreement gives FluoroScan exclusive rights to manufacture and distribute a
nonradioactive isotope version of NASA's low intensity X-ray and gamma ray
imaging device (patent no. 4,142,101). This technology provides the ability to
amplify X-rays that have been converted to visible light. This license
agreement and underlying patent previously had an expiration date of February
1996 but was extended as a result of GATT and now expires in July 1997. The
second agreement gives FluoroScan exclusive rights to manufacture and
distribute NASA's high voltage isolation transformer (patent no. 4,510,476)
and high voltage power supply (patent no. 4,517,472). This technology allows
FluoroScan products to produce low levels of radiation. This second license
and underlying patent previously had an expiration date of 2002 but was
extended as a result of GATT and now expires 2003. All three of these patents
are incorporated into FluoroScan technology. Pursuant to the licenses,
FluoroScan may be required to grant sublicenses to the extent that NASA
believes such sublicenses are necessary for the health and safety needs of the
United States and such needs cannot be fulfilled by FluoroScan. FluoroScan
must pay NASA royalties equal to 4.5% of the portion of the selling price of
each FluoroScan System that incorporates all of the licensed technology
attributable to NASA's patents. In the event FluoroScan sells a FluoroScan
System utilizing the technology covered by only the high voltage power supply
and high voltage isolation transformer patent, the royalty payment is reduced
to 3.5% of the patented portion of the selling price. Sales of products to the
United States government carry no royalty obligation, but the selling price of
such products must be reduced in an amount equal to the royalty that would
otherwise have been payable.
 
  Under an exclusive, perpetual consulting agreement with QTR Corporation
("QTR"), whose principals are the inventors of the technology underlying the
NASA patents, QTR provided certain technical expertise and assistance to
FluoroScan. In the past, FluoroScan paid QTR $300 per FluoroScan System sold
that utilized QTR's developments. FluoroScan incurred and paid royalties to
QTR of $37,200 and $44,400 in 1993, and 1994, respectively, pursuant to such
agreement. During the 1994 year, FluoroScan began to utilize alternative
technology and ceased payments to QTR Corporation.
 
  Both NASA license agreements allow FluoroScan to call to NASA's attention
any incidents of infringement and to suspend royalty payments if NASA does not
bring suit against the alleged infringer within six months. At such time as
the infringement is determined to have ended, the license agreements require
FluoroScan to pay the royalties previously suspended, offset by FluoroScan's
legal and other expenses incurred in prosecuting such infringement claims
minus any recoveries from infringement claims.

  In 1992, FluoroScan and the U.S. Department of Justice representing NASA
brought suit against Dow Corning Wright and Xi Tec for alleged infringement of
the NASA low intensity X-ray and gamma ray imaging device patent. In 1993, the
parties agreed to settle the litigation. As part of the settlement, the
defendants agreed to pay to FluoroScan a lump sum of $250,000 plus two
subsequent payments of $50,000 each. These payments were used by FluoroScan to
offset its litigation and other expenses and to pay NASA $50,000, representing
NASA's share of such settlement. In addition, FluoroScan granted Xi Tec a
nonexclusive, nonassignable and nontransferable sublicense under the NASA
license covering the X-ray and gamma ray imaging device patent which patent
previously had an expiration date of February 26, 1996 and was extended as a
result of GATT to July 1997. Under the sublicense, Xi Tec is obligated to pay
royalties to FluoroScan of $1,375 per covered device sold by Xi Tec during the
first 12 months of the license, $1,675 per covered device for the next 300
devices Xi Tec sells, and $1,375 per covered device sold thereafter through
the expiration date. From the royalties to be paid by Xi Tec to FluoroScan,
FluoroScan is obligated to pay $250 per device to NASA. In 1993, 1994 and
1995, Xi Tec incurred and paid royalties to FluoroScan of approximately
$97,625, $154,100 and $204,350, respectively, for sales of licensed products
reported by Xi Tec to FluoroScan. Of these royalties, FluoroScan incurred and
paid royalties of $17,750, $25,500 and $28,000 for 1993, 1994 and 1995,
respectively, to NASA.
 
  As the result of the alleged infringement, FluoroScan incurred legal and
other expenses of approximately $243,000 during 1993 and 1992. From 1987
through 1991, FluoroScan suspended royalty payments to NASA of $168,000.
Suspended royalties in 1992 and 1993 totaled approximately $105,000 and
$95,000, respectively.
 
  FluoroScan has also notified NASA that Lixi, may be infringing on the X-ray
and gamma ray imaging device patent. Lixi sells X-ray tube version lixiscopes
only in the industrial marketplace, to which FluoroScan makes sales
representing approximately 2% of total sales. On July 1, 1994, FluoroScan and
NASA entered into a settlement agreement relating to previously suspended
royalties. Pursuant to the terms of the settlement agreement, FluoroScan paid
NASA approximately $79,500 in respect of all suspended royalties through March
28, 1994 and agreed to pay 50% of royalties incurred after March 28, 1994,
with the remaining 50% payable either when the alleged Lixi infringement
ceases, when NASA sues Lixi or when the license covering the X-ray and gamma
ray imaging device patent expires. As a result of the settlement agreement,
FluoroScan realized a settlement gain of approximately $287,900 during the
third quarter of 1994. Suspended royalties as of December 31, 1994 and 1995
totaled $42,590 and $58,880, respectively.
 
  In addition to the patented NASA technology, FluoroScan considers certain of
its processes, design developments and improvements to be proprietary trade
secrets. FluoroScan may apply for patents on certain design developments in
the future.
 
GOVERNMENT REGULATION
 
  FluoroScan is required to obtain certain clearances, acceptances to market
and variances from the FDA to sell the FluoroScan System in the United States
health care market. The requisite clearances, acceptances to market and
variances have been obtained for the FluoroScan System. Variances are granted
for five-year periods and are renewable for an unlimited number of five-year
periods. FluoroScan's current variance expires April 12, 2000. Any new models
could, however, require additional clearances, acceptances to market and
variances. In addition to the FDA requirements, various states also impose
regulations on X-ray and fluoroscopic equipment. Management believes
FluoroScan has complied or received waivers from compliance with all such
regulations for FluoroScan products currently sold and in use. FluoroScan is
also subject to various ongoing reporting and other compliance requirements.
 
  FluoroScan may also be subject to certain state disclosure and other laws
that could be interpreted to impose certain restrictions on FluoroScan's
relationships with its independent sales representatives, including
restrictions on FluoroScan's ability to terminate such representatives without
advance notice and, in some cases, without cause. In 1994, FluoroScan settled
a lawsuit filed by a former sales representative who alleged, among other
things, failure to comply with such state laws. Such settlement is not
material to FluoroScan's financial condition or results of operations.

RESEARCH AND DEVELOPMENT
 
  For the years ended December 31, 1993, 1994 and 1995 research and
development expenditures amounted to $298,530, $213,462 and $306,110,
respectively. Such expenditures to date have focused on mechanical, electrical
and software engineering, as well as design and aesthetic improvements to the
FluoroScan System. In 1995, FluoroScan introduced the new hospital model
FluoroScan System III, which FluoroScan believes has become the industry
standard. Management expects to spend significant amounts on research and
development activities in subsequent years and to focus such activities on new
product development, expansion of applications for current products and
continued streamlining of manufacturing processes.
 
EMPLOYEES
 
  As of June 30, 1996, FluoroScan had 35 full-time employees; it occasionally
uses the services of temporary workers as well. FluoroScan considers its
employee relations to be good. None of FluoroScan's employees are represented
by a union.
 
PROPERTY
 
  FluoroScan's executive offices and manufacturing facilities have been
located at 650-B Anthony Trail, Northbrook, Illinois, since 1988. These
facilities, which consist of approximately 13,500 square feet of space, are
leased by FluoroScan pursuant to a lease which expires in February 1997.
Rental expense was $74,289, $78,750, and $103,933 for 1993, 1994, and 1995,
respectively. Under the terms of the lease, FluoroScan is also obligated to
pay its pro rata share of the annual real estate taxes and certain operating
expenses in excess of specified amounts. These additional payments were
approximately $5,200, $5,900 and $7,000 in 1993, 1994 and 1995, respectively.
 
  Of the leased space, approximately 6,250 square feet are used for
manufacturing, production and storage purposes, and approximately 7,250 square
feet are used for offices. FluoroScan is currently in negotiations to lease
additional space contiguous to its existing facility, which Management
believes would be sufficient to accommodate anticipated growth for the
foreseeable future.
 
  In 1995, FluoroScan International, Inc. entered into a three-year lease
agreement for an office facility in Paris, France. The agreement expires in
November, 1998, and has two three-year options to extend the lease,
exercisable at FluoroScan's discretion. Lease terms specify an annual rental
amount of FF199,250 (approximately $40,000) plus building maintenance charges.
 
LEGAL PROCEEDINGS
 
    FluoroScan is not presently involved in any legal proceedings which, if not
settled in favor of FluoroScan, would have a material adverse effect on its
financial condition.

  FLUOROSCAN MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
                             RESULTS OF OPERATIONS
 
RECENT DEVELOPMENTS
 
  For the three and six months ended June 30, 1996, FluroScan Imaging Systems,
Inc. reported net sales of $3,402,698 and $6,904,732, respectively, as
compared with net sales of $3,573,737 and $6,064,659 for the same periods
ended June 30, 1995. FluroScan Imaging Systems, Inc. also reported net income
for the three and six months ended June 30, 1996 of $165,794, or $0.05 per
share and $569,405 $0.16 per share, respectively, as compared with $417,689,
or $0.12 per share, and $758,311, or $0.22 per share, for the corresponding
periods ended June 30, 1995. See "Risk Factors."

</TABLE>
 
THREE MONTHS ENDED MARCH 31, 1995 AND 1996
 
  Net sales for the three months ended March 31, 1996 were $3,502,034 compared
with $2,490,922 for the three months ended March 31, 1995, an increase of
$1,011,112 or 40.6%. This increase was due primarily to increased sales of
four- and five-inch field-of-view FluoroScan Systems. This was partially
offset by the decline in sales of the three-inch field-of-view units.
FluoroScan believes that this was a result of a shift in market preference
toward four- and five-inch field of view FluoroScan System units, even though
these units are sold at higher unit prices. During the period ended March 31,
1996, FluoroScan also ceased production of the FluoroScan System I model,
which was replaced by the FluoroScan System III model in fourth quarter 1995.
The FluoroScan System III model is distinguished from earlier models in that
it has dual video and permanent image storage capabilities. The remaining
inventory of FluoroScan System I models was sold in first quarter 1996.
 
  FluoroScan's gross profit increased $542,954 or 37.4% for the three month
period ended March 31, 1996, as compared to the same period of 1995. Gross
profit as a percentage of net sales was 57.0% for the first three months of
1996, compared to 58.3% in the comparable period of 1995. This decrease
occurred primarily as a result of a greater percentage of four- and five-inch
field of view units in FluoroScan's sales mix. Although higher net sales and
gross profit are realized on such units, gross profit as a percentage of sales
was slightly lower than on the three-inch field of view units. Also
contributing to the gross profit percentage decline were lower margins on the
newly introduced FluoroScan System III model (which is slightly more expensive
to produce), relative to the FluoroScan System I model which it replaced.
 
  Selling, general and administrative expenses in the first three months of
1996 were $1,412,315 or 40.3% of net sales, compared with $1,020,377 or 40.9%
of net sales in the comparable period in 1995. This increase was primarily
attributable to higher commission expense, compensation costs, advertising and
tradeshow expenditures, as well as costs associated with FluoroScan's new
branch in France, which was opened in November 1994.
 
 
                                      77
<PAGE>
 
  FluoroScan's other income was $94,108 for the three months ended March 31,
1996, compared to $106,335 for the three months ended March 31, 1995, a
decrease of $12,227. This was primarily due to the expiration in February 1996
of a sublicense agreement under which FluoroScan previously had been recording
royalty income.
 
  Net income was $403,611 or $0.12 per share for the three months ended March
31, 1996, based on weighted average common shares outstanding of 3,495,417.
This represented an 18.5% increase in net income from the comparable 1995
period amount of $340,622 or $0.10 per share based on weighted average common
shares and share equivalents outstanding of 3,506,538.
 
YEARS ENDED DECEMBER 31, 1994 AND 1995
 
  FluoroScan's net sales for 1995 were $13,146,979, compared with $9,170,505
for 1994, an increase of $3,976,474 or 43.4%. This increase was generated from
several sources. Most of the increase can be attributed to sales of four- and
five-inch field-of-view FluoroScan System I units, which more than tripled
from 1994 levels. Such units were first introduced in June 1994. Sales of the
FluoroScan System II veterinary units, which FluoroScan began selling in
August 1994, more than doubled in 1995. Net sales in 1995 also benefited from
the February introduction of FluoroScan's new generation VGA video enhancement
system and the new FluoroScan System III model, which FluoroScan began selling
in November 1995. These increases in 1995 were partially offset by the decline
in sales of the three-inch field-of-view units. Management believes that this
was a result of a shift in market preference toward four- and five-inch field-
of-view FluoroScan System units, even though these are sold at higher unit
prices.
 
  FluoroScan's gross profit increased $2,175,096 or 39.4% in 1995, compared
with the prior year. FluoroScan's gross profit as a percentage of net sales
was 58.5% for 1995, compared with 60.1% in 1994. The decrease occurred
primarily as a result of a greater percentage of four- and five-inch field-of-
view units in FluoroScan's sales mix. Although higher net sales and gross
profit are realized on such units, gross profit as a percentage of sales was
slightly lower than on the three-inch field-of-view units.
 
  Selling, general and administrative expense for 1995 was $5,832,622 or 44.4%
of net sales, compared with $3,720,521 or 40.6% of net sales in 1994. This
increase was primarily attributable to new product introduction costs and
higher commission expense, compensation costs, investor relations expense and
royalty expense. In the third quarter of 1994, FluoroScan entered into an
agreement with NASA with respect to suspended royalties. Accordingly, cash
flow was reduced, as was the balance sheet liability for royalties, by the
amount paid to NASA (approximately $79,500), and the excess of the balance
sheet liability over the amount so paid (approximately $287,900) was reported
as a reduction of selling, general and administrative expenses.
 
  FluoroScan's other income was $485,409 for 1995 compared to $271,434 for the
prior year, an increase of $213,975. This was due primarily to an increase in
interest income and royalty income.
 
  The income tax expense in 1994 of $292,000 was significantly affected by the
adjustment of the tax asset valuation allowance by $597,000. This allowance
was fully utilized as of December 31, 1994. FluoroScan incurred income tax
expense of $863,000 in 1995.
 
  Net income was $1,478,737 or $0.43 per share for 1995, based on weighted
average common shares and share equivalents outstanding of 3,472,519. This
includes 715,216 shares issued in connection with FluoroScan's July 1994
initial public offering and weighted fully in the 1995 year. Net income
decreased 16.6% from the 1994 period income of $1,772,767 or $0.57 per share
based on weighted average common shares and share equivalents outstanding of
3,106,721. Net income was significantly impacted by the reduction of the tax
asset valuation allowance in 1994. Tax expense, net income and net income per
common share would have been $937,000, $1,404,737 and $0.40, respectively, for
1995 compared to $826,000, $1,238,860 and $0.40, respectively, for 1994 had
FluoroScan provided taxes at a combined statutory rate of 40% in 1994.

<PAGE>
 
YEARS ENDED DECEMBER 31, 1993 AND 1994
 
  Net sales for 1994 were $9,170,505, compared with $6,927,761 for 1993, an
increase of $2,242,744 or 32.4%. The introduction of four- and five-inch
field-of-view FluoroScan System units, domestically and abroad, accounted for
90.8% of this increase. International sales, which increased 122.4% in 1994
over 1993, also contributed to the total year-to-year increase. Sales of
three-inch field-of-view units declined 4.5%. Management believes that this
was a result of a shift in market preference toward four-inch field-of-view
FluoroScan System units, which FluoroScan sells at higher unit prices.
 
  FluoroScan's gross profit increased $1,318,629 or 31.4% for the year ended
December 31, 1994, compared to the year ended December 31, 1993. FluoroScan's
gross profit as a percentage of net sales declined from 60.6% in 1993 to 60.1%
in 1994. The decrease resulted from a greater percentage of international
sales in the sales mix, as well as lower margins on four- and five-inch field-
of-view FluoroScan System units. Sales to international distributors are
discounted, with no commission expense. Four- and five-inch field-of-view
FluoroScan System units were introduced in the second quarter of 1994 and were
priced for immediate market acceptance. Although FluoroScan realized higher
net sales and gross profit on such units, gross profit as a percentage of net
sales was slightly lower than on the three-inch field-of-view units.
 
  Selling, general and administrative expense for 1994 was $3,720,521 or 40.6%
of net sales, compared with $3,493,466 or 50.5% of net sales in 1993.
Significant increases occurred in sales commissions, compensation costs, and
shipping and freight charges. These were partially offset by reductions in
research and development expenses and a benefit to FluoroScan resulting from
an agreement with NASA with respect to suspended royalties during the third
quarter of 1994. Accordingly, cash flow was reduced, as was the balance sheet
liability for royalties, by the amount paid to NASA (approximately $79,500),
and the excess (approximately $287,900) of the balance sheet liability over
the amount so paid was reported as income to FluoroScan.
 
  In 1993, other income included $154,091 in patent litigation settlement
proceeds, net of litigation costs. In 1994, other income included a $106,783
increase in interest income over the 1993 amount.
 
  FluoroScan had a tax loss carryforward from prior years equal to
approximately $673,300, which would have expired in specified amounts between
the years 2002 and 2004. Because FluoroScan is exempt from the Internal
Revenue Code Section 382 limitations on loss carryforwards, all of these
losses were deemed to be available. FluoroScan adopted Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes," effective January
1, 1992, but due to FluoroScan's then-recent bankruptcy the entire tax asset
was fully reserved as the valuation allowance. Because of FluoroScan's
increased profitability in 1994 and 1993, management determined that future
taxable income would likely be sufficient to adjust the valuation allowance
and realize the tax asset. The income tax expense in 1994 of $292,000 and the
income benefit in 1993 of $485,000 reflect the adjustment of the valuation
allowance by $597,000 and $897,000, respectively, as described in the notes to
consolidated financial statements.
 
  Net income was $1,772,767 or $0.57 per share for 1994, based on weighted
average common shares and share equivalents outstanding of 3,106,721. This
represented a 21.6% increase over the net income for 1993 of $1,458,324 or
$0.52 per share, based on weighted average common shares and share equivalents
outstanding of 2,787,303.
 
  The adjustment to the valuation allowance with respect to deferred tax
assets significantly affected FluoroScan's provision for taxes on income.
Since no valuation allowance remained at December 31, 1994, such adjustments
are not expected to continue. Tax expense, net income and net income per
common share would have been $826,000, $1,238,860 and $0.40, respectively, for
1994 compared to $389,000, $583,994 and $0.21, respectively, for 1993 had
FluoroScan provided taxes at a combined statutory rate of 40% in each of these
periods.

 Liquidity and Capital Resources
 
  FluoroScan's working capital requirements have primarily related to its
level of sales. Working capital at March 31, 1996 was $8,248,456 representing
increase of $428,777 from December 31, 1995. This increase was primarily
attributable to higher accounts receivable which increased due to a higher
level of sales concentrated at the end of the quarter. This was, in part,
offset by increases in taxes payable. Cash used in operating activities
amounted to $97,653 for the three months ended March 31, 1996. In the
comparable period of 1995, cash provided by operating activities was $118,574.
The aforementioned increase in accounts receivable in the first quarter of
1996 was the primary reason for this difference.
 
  FluoroScan currently has no long-term debt. As of December 31, 1994,
FluoroScan had a $300,000 line-of-credit. No borrowings were made on the line-
of-credit and FluoroScan elected not to renew this credit facility upon its
expiration in May, 1995. FluoroScan believes cash balances, which totaled
$5,316,908 at March 31, 1996, and internally generated funds will be
sufficient to meet its liquidity needs for the foreseeable future. FluoroScan
may use portions of its cash balance to fund increases in sales and marketing
programs and in research and development. Such cash investments, while
designed to increase net sales, would increase selling, general and
administrative expenses.
 
  Capital expenditures for the three months ended March 31, 1996 were $24,039,
compared with $67,842 in the comparable period of the prior year. Expenditures
primarily consisted of purchases of computer and office equipment.
 
  Capital expenditures in 1995 were $239,970, compared with $395,409 in 1994.
Expenditures in 1995 consisted primarily of manufacturing equipment and
computer equipment and software. The majority of prior year expenditures
related to tooling and molds associated with the development of new products,
computer equipment, and leasehold improvements.

(2) The amount "realized" reflects the appreciation on the date of exercise
    (based on the excess of the fair market value of the shares on the date of
    exercise over the exercise price). However, because the executive officers
    may keep the shares they acquired upon the exercise of the options (or
    sell them at a different price), these amounts do not necessarily reflect
    cash realized upon the sale of those shares.

  Executive Bonus Program. The Compensation Committee of the Board of
Directors approved an Executive and Key Employee Bonus Program for fiscal 1996
under which executive officers, senior management and key contributors
selected by the Compensation Committee may be eligible for cash bonuses,
awarded at the discretion of the Compensation Committee, to be paid in the
first quarter of fiscal 1997. Under this program, if pre-tax profits exceed
$2,000,000, a bonus pool is expected to be created equal to up to 8% of
Hologic's pre-tax

profits. If pre-tax profits exceed $1,000,000 and are $2,000,000 or less, a
bonus pool is expected to be created equal to up to 8% of Hologic's pre-tax
profits which exceed a base amount of $1,000,000. No bonus pool is expected to
be created if Hologic's pre-tax profits do not exceed $1,000,000. For fiscal
1995, bonuses of $225,000 were granted under an identical program approved for
that year.

administers Hologic's 1986 Combination Stock Option Plan, the Employee Stock
Purchase Plan, will administer Hologic's Executive and Key Employee Bonus
Program for fiscal 1996 and will administer Hologic's 1995 Combination Stock

                             CERTAIN TRANSACTIONS
 
  For the fiscal year ended September 30, 1995, the following transactions
occurred which involved more than $60,000 between Hologic and any director,
executive officer, five percent (5%) beneficial owner of Hologic's Common
Stock or any member of the immediate family of any of the foregoing persons.
 
VIVID TECHNOLOGIES, INC.
 
  In June 1989, Hologic granted an exclusive worldwide license of certain of
its QDR technology to Vivid Technologies, Inc. ("Vivid") for the sole purpose
of developing a baggage inspection and security system. Mr. Ellenbogen and Dr.
Stein are directors of Vivid and hold similar offices in Vivid as they do in
Hologic. Mr. Ellenbogen and Dr. Stein collectively own approximately 23% of
the outstanding voting stock of Vivid.
 
  In return for its license of the QDR technology, Vivid is required to pay
Hologic royalties of 5% of the first $50 million of net sales of products
using Hologic's technology, and 3% of net sales in excess of $50 million, up
to a maximum of $200 million of net sales. The maximum aggregate royalties
payable by Vivid to Hologic under this arrangement are $7 million. In fiscal
1995, Vivid paid Hologic royalties of approximately $719,000 under the License
Agreement.
 
  Under a management agreement, Hologic has agreed to provide Vivid with
management, engineering and administrative support, and had provided space at
Hologic's facilities. Vivid vacated this space in the second quarter of fiscal
1996. The support services provided by Hologic under this arrangement include
the part-time management services of Mr. Ellenbogen and Dr. Stein and other
managerial personnel, and secretarial, telephone and similar services. Vivid
is required to pay Hologic its proportionate share of Hologic's overhead,
including rent and the salary of Hologic's employees rendering services to
Vivid. Under this arrangement, no compensation is paid by Vivid to any of
Hologic's employees. The management agreement may be terminated by either
party on six month's written notice. For the fiscal year ended September 30,
1995, Vivid was charged approximately $740,000 by Hologic for services
rendered under the agreement, manufactured sub-assemblies, spare parts and
space at Hologic's facilities. In December 1995, Vivid paid Hologic a $40,000
bonus for the management services provided in fiscal 1995. Hologic estimates
that Mr. Ellenbogen and Dr. Stein have each been spending approximately
sixteen and eight hours per week, respectively, on matters involving Vivid.
 
INDEBTEDNESS
 
  In fiscal 1995, Steve L. Nakashige, the President and Chief Operating
Officer of Hologic, borrowed an aggregate of $161,000 from Hologic pursuant to
a bridge loan to assist Mr. Nakashige in the purchase of a local primary
residence in connection with his relocation to Massachusetts. In fiscal 1995,
Mark A. Duerst, the Vice President of Sales and Marketing of Hologic, borrowed
an aggregate of $155,000 from Hologic pursuant to a bridge loan to assist Mr.
Duerst in the purchase of a local primary residence in connection with his
relocation to Massachusetts. Both loans had no stated interest rate and have
been repaid in full.

                      DESCRIPTION OF HOLOGIC COMMON STOCK
 
  Hologic's authorized capital stock consists of 30,000,000 shares of Common
Stock, $.01 par value, and 1,622,685 shares of Preferred Stock, $.01 par value
(the "Hologic Preferred Stock").
 
HOLOGIC COMMON STOCK
 
  The holders of Hologic Common Stock are entitled to one vote per share on
all matters to be voted on by stockholders and are entitled to receive such
dividends, if any, as may be declared from time to time by the Board of
Directors from funds legally available therefor. Upon liquidation or
dissolution of Hologic, the holders of Hologic Common Stock are entitled to
receive all assets available for distribution to the stockholders, subject to
any preferential or other rights of the holders of Preferred Stock. Hologic
Common Stock has no preemptive or other subscription rights, and there are no
conversion rights or redemption or sinking fund provisions with respect to
such shares. The holders of Hologic Common Stock are entitled to one vote for
each share held of record on all matters submitted to a vote of stockholders.
The holders of Hologic Common Stock do not have cumulative voting rights in
the election of directors. All of the shares of Hologic Common Stock are, and
the shares to be delivered upon consummation of the Merger will be, fully paid
and non assessable.
 
  As of August 5, 1996, there were 11,310,790 shares of Hologic Common Stock
outstanding, held of record by approximately 262 stockholders.
 
PREFERRED STOCK
 
  Hologic is authorized to issue up to 1,622,685 shares of Hologic Preferred
Stock, none of which are outstanding. The Board of Directors may, without
future action of the stockholders of Hologic, issue the Hologic Preferred
Stock in one or more classes or series and fix the rights and preferences
thereof, including the dividend rights, dividend rates, conversion rights,
voting rights, terms of redemption (including sinking fund provisions),
redemption price or prices, liquidation preferences and the number of shares
constituting any class or series, or the designations of such class or series.
 
  The voting and other rights of the holders of Hologic Common Stock will be
subject to, and may be adversely affected by, the rights of holders of any
Hologic Preferred Stock that may be issued in the future. Issuances of Hologic
Preferred Stock, while providing desirable flexibility in connection with
possible acquisitions and other corporate purposes, could have the effect of
making it more difficult for a third party to acquire, or of discouraging a
third party from acquiring, a majority of the outstanding voting stock of
Hologic. Hologic has no present plans to reissue any shares of Hologic
Preferred Stock.
 
CERTAIN PROVISIONS AFFECTING STOCKHOLDERS
 
  In addition to the Hologic Preferred Stock, the Hologic Certificate of
Incorporation includes several additional provisions which may render more
difficult an unfriendly tender offer, proxy content, merger or other change in
control of Hologic. These provisions may discourage bids for Hologic and
therefore may limit the price that certain investors might be willing to pay
in the future for shares of Hologic Common Stock.
 
  The Hologic Certificate of Incorporation contains a so-called "anti-
greenmail" provision. The provision is intended to discourage speculators who
accumulate beneficial ownership of a significant block of stock and then,
under the threat of making a tender offer or proxy contest or instigating some
other corporate disruption, succeed in extracting from the corporation a
premium price to repurchase the shares acquired by the speculator. This tactic
has become known as greenmail. The anti-greenmail provision prohibits Hologic
from purchasing any shares of Hologic Common Stock from a related person at a
per share price in excess of the fair market value at the time of such
purchase, unless the purchase is approved by two-thirds of the holders of the
outstanding shares of Hologic Common Stock, excluding any votes cast by the
Related Person. The term Related Person is defined in general to mean any
person, other than a founder of Hologic (Mr. Ellenbogen and Dr. Stein), who
acquires more than 5% of Hologic's voting stock. Stockholder approval is not
required for such purchases when the offer is made available on the same terms
to all holders of shares of Hologic Common Stock or when the purchases are
effected on the open market.
 
                                      91
<PAGE>
 
  The Hologic Certificate of Incorporation also contains a provision that will
require the affirmative vote of the holders of 80% of the outstanding Hologic
Common Stock to approve amendments to the Hologic Certificate of Incorporation
or to approve extraordinary transactions that are required to be approved by
stockholders under Delaware Law, including mergers, sales of substantially all
of Hologic's assets and dissolution, which actions are not approved by a
majority of the continuing Directors (as defined below) of Hologic. The
Hologic Certificate of Incorporation provides that the affirmative vote of the
holders of only a majority of the outstanding Hologic Common Stock is required
to approve such matters if they have been approved by the Continuing
Directors. The term Continuing Director is defined to mean (i) any member of
the Board of Directors who is unaffiliated with a Related Person and was a
member of the Board of Directors prior to the time any person became a Related
Person and (ii) any successor to such a Continuing Director who is not
affiliated with any Related Person and is recommended to succeed a Continuing
Director by a majority of the Continuing Directors then on the Board of
Directors. A majority of the Continuing Directors can designate a new director
to be a Continuing Director, even though such person is affiliated with a
Related Person.
 
  The Continuing Directors are currently closely affiliated with management
and are anticipated to continue to be so into the foreseeable future.
Accordingly, the effect of the provision of Hologic's Certificate of
Incorporation described in the preceding paragraph would be to make it
unlikely that any transaction requiring a stockholder vote would receive the
requisite approval unless supported by management. The 80% voting requirement
would apply to recapitalizations, management-led buy-outs and other
management-led transactions requiring the vote of stockholders under the
Delaware Law, if such transactions were not approved by the Continuing
Directors to management. However, because of the likelihood of the close
association of the Continuing Directors to management, it would be more likely
that such transactions would obtain the approval of the Continuing Directors
and require only majority stockholder approval.
 
  Another provision included in the Hologic Certificate of Incorporation
requires the Board of Directors to consider social, economic and other factors
in evaluating whether certain types of corporate transactions proposed by
another party are in the best interests of Hologic and its stockholders. These
transactions include (i) the purchase or acquisition through exchange or
otherwise of any of Hologic's outstanding equity securities, (ii) the merger
or consolidation of Hologic with another corporation and (iii) the purchase or
other acquisition of all or substantially all of Hologic's properties and
assets.
 
  Section 203 of the Delaware General Corporation Law prohibits a Delaware
corporation from engaging in a wide range of specified transactions with any
interested stockholder, defined to include, among others, any person or entity
who in the last three years obtained 15% or more of any class or series of
stock entitled to vote in the election of directors, unless, among other
exceptions, the transaction is approved by (i) the Board of Directors prior to
the date the interested stockholder obtained such status or (ii) the holders
of two-thirds of the outstanding shares of each class or series of stock
entitled to vote generally in the election of directors, not including those
shares owned by the interested stockholder. By virtue of Hologic's decision
not to elect out of the statute's provisions, the statute applies to Hologic.
 
RIGHTS DISTRIBUTION
 
  In 1992, the Board of Directors declared a dividend distribution of one
right (a "Right") for each outstanding share of Hologic Common Stock held of
record on December 22, 1992 or issued thereafter prior to "Separation Time,"
as defined below. After December 22, 1992 and for so long as the Rights are
not transferable separately from the Hologic Common Stock, one Right is deemed
to be delivered with each share of Hologic Common Stock issued or transferred
by Hologic.
 
  The "Separation Time" is the close of business on the earlier of (i) the
tenth business day (or such earlier or later date not beyond the thirtieth day
as of the Board of Directors may decide) (a "Flip-in Date"), after the
 
                                      92
<PAGE>
 
announcement that a person has acquired 15% or more of the outstanding Hologic
Common Stock of Hologic (or that a person already owning 15% has acquired any
more Hologic Common Stock) (an "Acquiring Person") or (ii) the tenth business
day (or such later date as the Board of Directors may decide) after any person
commences a tender or exchange offer to acquire beneficial ownership of 15% or
more of the outstanding shares of Hologic Common Stock. Until the Separation
Time, the Rights will be evidenced solely by the Hologic Common Stock
certificates and may be transferred only with the Hologic Common Stock.
 
  After the Separation Time, the Rights become exercisable and may be
transferred independently of shares of Hologic Common Stock, and separate
certificate evidencing the Rights will be mailed to stockholders. The Rights
will expire on the earlier of (i) December 22, 2002, or (ii) the date on which
the Rights are redeemed.
 
  Commencing after the Flip-in Date has occurred, the holders of Rights,
except the Acquiring Person, are entitled to purchase the number of shares of
Hologic's Hologic Common Stock having a market value equal to twice the
exercise price of $15 per share (the "Exercise Price"). However, in lieu of
the rights to purchase shares of Hologic's Hologic Common Stock at an
effective 50% discount, the Board of Directors of Hologic may elect to issue
one share of Hologic Common Stock for each Right held by each holder other
than the Acquiring Person.
 
  After the Acquiring Person has become such, and prior to the expiration of
the Rights, Hologic may not (i) consolidate or merge with any other person,
(ii) sell or otherwise transfer to any other person more than 50% of Hologic's
assets, or assets generating more than 50% of Hologic's operating income or
cash flow, (iii) engage in certain self-dealing transactions with Acquiring
Persons, or (iv) permit certain events to occur when there is an Acquiring
Person, if at the time of such merger, sale or self-dealt transaction the
Acquiring Person controls the board of directors and, in the case of merger,
will receive different treatment than other stockholders, unless in any such
case provision is made so that each holder of a Right will thereafter have the
right to receive, at the then current Exercise Price, a number of shares of
common stock of the Acquiring Person engaging in the transaction having a
market value equal to two times the Exercise Price of the Right.
 
  The Rights may be terminated by Hologic at any time prior to the close of
business on a Flip-in Date.
 
  The provisions in the Certificate of Incorporation and By-Laws referred to
above, and the authority of the Board of Directors to issue additional shares
of Hologic Common Stock and accelerate the exercisability of the Rights could
be used by the Board of Directors in a manner calculated to prevent the
removal of management and make more difficult or discourage a change in
control of Hologic. The distribution of Rights and certain aspects of the
foregoing provisions in Hologic's Certificate of Incorporation and By-Laws
were designed to afford the Board of Directors the opportunity to evaluate the
terms of a takeover attempt without haste or undue pressure, advise
stockholders of its findings, and to negotiate to protect the interests of all
stockholders. See "Risk Factors--Anti-takeover Provisions; Management
Control."
 
TRANSFER AGENT AND REGISTRAR
 
  The transfer agent and registrar for Hologic's Common Stock is American
Stock Transfer and Trust Company.

        COMPARISON OF RIGHTS OF STOCKHOLDERS OF HOLOGIC AND FLUOROSCAN
 
  The following is a summary of certain of the material differences between
the rights of holders of Hologic Common Stock and the rights of holders of
FluoroScan Common Stock. Hologic and FluoroScan are each organized under the
laws of the State of Delaware, therefore, such differences arise from
differences between various provisions of the Certificate of Incorporation,
By-Laws and Rights Agreement of Hologic (the "Hologic Charter Documents") and
the Amended and Restated Certificate of Incorporation and By-Laws of
FluoroScan (the "FluoroScan Charter Documents"). For a complete description of
the rights of holders of Hologic Common Stock, see "Description Of Hologic
Capital Stock."
 
NUMBER, CLASSIFICATION AND REMOVAL OF DIRECTORS
 
  The Hologic Charter Documents provide that the number of directors of
Hologic shall be fixed by the Board of Directors or by the vote of the holders
of 80% of the outstanding voting stock of Hologic, and that any one or more of
the directors may be removed from office only with cause, by a vote of the
majority of the directors then in office or by a vote of the holders of 80% of
the outstanding voting stock of Hologic. Hologic does not have a classified
Board of Directors and each director holds office from the time such person is
elected until the next annual meeting of the stockholders of Hologic and
thereafter until their successors are chosen and qualified.
 
  The FluoroScan Charter Documents provide that the number of directors of
FluoroScan shall be fixed by a majority of the directors in office, and that
any one or more of the directors may be removed, with or without cause, by the
vote of the holders of a majority of the outstanding voting stock of
FluoroScan entitled to vote on the election of directors; provided, however,
that if cumulative voting is permitted and less than the entire Board of
Directors is to be removed, no director may be removed without cause if the
votes cast against the removal of such director would be sufficient to elect
such director if cumulatively voted at an election of the entire Board of
Directors. FluoroScan has a classified Board of Directors consisting of one
Class I Director, two Class II Directors and two Class III Directors. Pursuant
to FluoroScan Charter Documents, directors are elected for terms ending three
years from the annual meeting of FluoroScan stockholders at which such
director was last elected.
 
CERTAIN ADDITIONAL PROVISIONS AFFECTING STOCKHOLDERS
 
  The Hologic Charter Documents contain additional provisions which are not
contained in FluoroScan Charter Documents, which provisions may render more
difficult an unfriendly tender offer, proxy contest, merger or other change in
control. These provisions include a so-called "anti-greenmail" provision, a
super-majority voting provision, and a provision that requires the Board of
Directors to consider social, economic and other factors in evaluating whether
certain types of corporate transactions proposed by another party are in the
best interests of Hologic and its stockholders. See "Description Of Hologic
Capital Stock--Certain Provisions Affecting Stockholders." The Hologic Charter
Documents also include the Rights Agreement, pursuant to which one right is
distributed with each share of Hologic Common Stock. Each right entitles each
eligible holder thereof, under certain circumstances, to receive or purchase
additional shares of Hologic Common Stock. See "Description Of Hologic Capital
Stock--Rights Distribution." The FluoroScan Charter Documents contain no such
provisions.
 
  The foregoing summary does not purport to be a complete statement of the
rights of holders of Hologic Common Stock and FluoroScan Common Stock under,
and is qualified in its entirety by reference to, the Delaware Law, the
Hologic Charter Documents, and FluoroScan Charter Documents. See "Description
Of Hologic Capital Stock" for a more detailed summary of certain rights
relating to Hologic Common Stock .

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Hologic, Inc.:
 
  We have audited the accompanying consolidated balance sheets of Hologic,
Inc. (a Delaware corporation) and subsidiaries as of September 24, 1994 and
September 30, 1995, and the related consolidated statements of operations,
stockholders' equity and cash flows for each of the three years in the period
ended September 30, 1995. These financial statements are the responsibility of
the Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Hologic, Inc. and
subsidiaries as of September 24, 1994 and September 30, 1995, and the results
of their operations and their cash flows for each of the three years in the
period ended September 30, 1995, in conformity with generally accepted
accounting principles.
 
  Our audit was made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The schedule listed in Item 21(b) is
the responsibility of the Company's management and is presented for purposes
of complying with the Securities and Exchange Commission's rules and is not
part of the basic financial statements. This schedule has been subjected to
the auditing procedures applied in the audit of the basic financial statements
and, in our opinion, fairly states in all material respects the financial data
required to be set forth therein in relation to the basic financial statements
taken as a whole.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
               (INCLUDING DATA APPLICABLE TO UNAUDITED PERIODS)
 
 
(1) OPERATIONS
 
  Hologic, Inc. (the Company) is engaged in the development, manufacture and
distribution of proprietary x-ray and other medical systems.
 
(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  The accompanying consolidated financial statements reflect the application
of certain accounting policies as described in this note and elsewhere in the
accompanying consolidated financial statements.
 
 (a) Principles of Consolidation
 
  The accompanying consolidated financial statements include the accounts of
the Company and all of its wholly owned subsidiaries. All material
intercompany accounts and transactions have been eliminated in consolidation.
 
 (b) Change in Fiscal Year
 
  During fiscal 1993, the Company elected to change its fiscal year-end from
September 30 to the last Saturday in September. Fiscal 1993, 1994 and 1995
ended on September 25, 1993, September 24, 1994 and September 30, 1995.
 
 (c) Management Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements, and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
 (d) Stock Split
 
  On March 25, 1996, the stockholders of the Company approved a two-for-one
stock split of the Common Stock. The stock split has been retroactively
reflected in the accompanying consolidated financial statements and notes for
all periods presented.
 
 (e) Cash and Cash Equivalents and Short-term Investments
 
  The Company considers all highly liquid investments with maturities of three
months or less at the time of acquisition to be cash equivalents. Included in
cash equivalents at September 24, 1994 is approximately $4,804,000 of
securities purchased under agreements to resell. Included in cash equivalents
at September 30, 1995 is approximately $4,217,000 of securities purchased
under agreements to resell. Included in cash equivalents at March 30, 1996 is
approximately $4,567,000 of securities purchased under agreements to resell.
The securities purchased under agreements to resell are collateralized by U.S.
Government securities. Short-term investments have maturities of greater than
three months and consist of securities issued by the U.S. Government and its
agencies.
 
  The Company accounts for investments in accordance with the Statement of
Financial Accounting Standards (SFAS) No. 115, Accounting for Certain
Investments in Debt and Equity Securities. Under SFAS No. 115, investments
that the Company has the positive intent and ability to hold to maturity are
reported at amortized cost, which approximates fair market value, and are
classified as held-to-maturity. These investments include cash, cash
equivalents and securities issued by U.S. Government agencies, which total
approximately $6,522,000 and $57,311,000 at September 30, 1995 and March 30,
1996, respectively. Investments purchased to be held for indefinite periods of
time and not intended at the time of purchase to be held until maturity are
classified as available-for-sale, which total approximately $1,803,000 at
September 30, 1995. These investments consist of securities issued by the U.S.
Government and are carried at cost which approximates fair market value.

               (INCLUDING DATA APPLICABLE TO UNAUDITED PERIODS)
 
 (f) Concentration of Credit Risk
 
  SFAS No. 105, Disclosure of Information about Financial Instruments with
Off-Balance-Sheet Risk and Financial Instruments with Concentration of Credit
Risk, requires disclosure of any significant off-balance-sheet and credit risk
concentrations. Financial instruments that subject the Company to credit risk
consist primarily of trade accounts receivable. The Company utilizes
distributors in certain countries with various credit terms, depending on the
individual circumstances. One distributor had amounts due to the Company of
approximately $4,817,000, $2,231,000 and $3,355,000 as of September 24, 1994,
September 30, 1995 and March 30, 1996, respectively. This distributor
accounted for 14%, 28% and 20% of product sales for fiscal 1993, 1994 and
1995, respectively and 32% and 20% for the six months ended March 25, 1995 and
March 30, 1996, respectively.

</TABLE>
 
  Work-in-process and finished goods inventories consist of materials, labor
and manufacturing overhead.
 
 (h) Depreciation and Amortization
 
  The Company provides for depreciation and amortization by charges to
operations, using the straight-line and declining-balance methods, which
allocate the cost of property and equipment over the following estimated
useful lives:

             Furniture and fixtures.....     5-7 Years
             Leasehold improvements..... Life of lease
</TABLE>
 
 (i) Intangible Assets
 
  The Company assesses the realizability of intangible assets in accordance
with SFAS No. 121, Accounting for Impairment of Long-lived Assets and for
Long-lived Assets To Be Disposed Of.
 
 (j) Foreign Currency Translation
 
  The Company translates certain of its accounts and the financial statements
of its foreign subsidiaries in accordance with SFAS No. 52, Foreign Currency
Translation. In translating the accounts of the foreign subsidiaries into U.S.
dollars, assets and liabilities are translated at the rate of exchange in
effect at year-end, while stockholders' equity is translated at historical
rates. Revenue and expense accounts are translated using the weighted average
exchange rate in effect during the year. Gains and losses from foreign
currency translation are credited or charged to cumulative translation
adjustment, included in stockholders' equity in the accompanying consolidated
balance sheets.
 
  Transaction losses of approximately $430,000 in fiscal 1993 are included in
other expense in the accompanying consolidated statements of operations.
Transaction gains in fiscal 1994, 1995 and for the six months ended March 25,
1995 and March 30, 1996 were not significant.

               (INCLUDING DATA APPLICABLE TO UNAUDITED PERIODS)
 
 (k) Revenue Recognition
 
  The Company recognizes product revenue upon shipment. A provision is made at
that time for estimated warranty costs to be incurred. Other revenues are
recorded at the time the product is shipped or the service rendered.
 
  Maintenance revenues are recognized over the term of the contract. Cash
received in excess of revenues recognized is included in deferred revenue in
the accompanying consolidated balance sheets.
 
 (l) Research and Development and Software Development Costs
 
  Research and development costs, other than software development costs, have
been charged to operations as incurred. SFAS No. 86, Accounting for the Costs
of Computer Software To Be Sold, Leased or Otherwise Marketed, requires the
capitalization of certain computer software development costs incurred after
technological feasibility is established. The Company believes that once
technological feasibility of a software product has been established, the
additional development costs incurred to bring the product to a commercially
acceptable level are not significant.
 
 (m) Net Income (Loss) per Common and Common Equivalent Share
 
  Net income (loss) per share data are computed using the weighted average
number of shares of common stock outstanding during each period. Common
equivalent shares from stock options have been included in the computation
using the treasury stock method only when their effect would be dilutive.
Fully dilutive net income per share has been separately presented only when
the difference from primary net income per share is significant.
 
 (n) Restructuring Charge
 
  In fiscal 1993, the Company recorded a nonrecurring restructuring charge of
$900,000, representing the costs associated with reorganizing its European
operations. These costs included a reduction in work force, consolidation of
distribution and administrative functions, and asset write-offs and write-
downs. The restructuring was completed during the fourth quarter of fiscal
1994.
 
 (o) Derivative Financial Instruments
 
  During October 1994, the Financial Accounting Standards Board issued SFAS
No. 119, Disclosure About Derivative Financial Instruments and Fair Value of
Financial Instruments, which requires disclosures about derivative financial
instruments. SFAS No. 119 will be effective for fiscal 1996. The Company does
not expect the adoption of this standard to have a material effect on its
consolidated financial position or results of operations. At September 30,
1995 and March 30, 1996, the Company had no instruments requiring disclosure
under SFAS No. 119.
 
 (p) Interim Financial Statements
 
  The accompanying consolidated balance sheet as of March 30, 1996, the
consolidated statements of operations and cash flows for the six months ended
March 25, 1995 and March 30, 1996, and the consolidated statement of
stockholders' equity for the six months ended March 30, 1996 are unaudited,
but, in the opinion of management, have been prepared on a basis substantially
consistent with the audited financial statements and include all adjustments,
consisting only of normal recurring adjustments, necessary for a fair
presentation of the results of these interim periods. The results of the six
months ended March 30, 1996 are not necessarily indicative of the results to
be expected for the year ended September 28, 1996.

               (INCLUDING DATA APPLICABLE TO UNAUDITED PERIODS)
 
(3) LINE OF CREDIT
 
  The Company maintains a line of credit with a bank for the equivalent of
$3,000,000, which bears interest at the Paris Interbank Offered Rate (6.375%
at September 30, 1995) plus 2.25%. The borrowings under this line are
primarily used by the Company's European subsidiaries to settle intercompany
sales and are denominated in the respective local currencies of its European
subsidiaries. The line of credit may be canceled by the bank with a 30-day
notice. Interest expense on this line of credit of approximately $79,000 and
$204,000 has been included in other expenses in the accompanying consolidated
statements of operations for 1994 and 1995, respectively and approximately
$92,000 and $78,000 for the six months ended March 25, 1995 and March 30,
1996, respectively.
 
(4) INCOME TAXES
 
  The Company provides for income taxes under the liability method in
accordance with SFAS No. 109, Accounting for Income Taxes.
 
  The provision (benefit) for income taxes in the accompanying consolidated
statements of operations consists of the following:

  The valuation allowance relates primarily to certain deferred tax assets in
foreign jurisdictions, for which realization is uncertain. The reduction in
the valuation allowance in 1995 is directly attributable to the reduction of
foreign net operating losses.

 (c) Rights Agreement
 
  In December 1992, the Company adopted a shareholder rights plan. The plan is
intended to protect shareholders from unfair or coercive takeover practices.
In accordance with the plan, the Board of Directors declared a dividend
distribution of one common stock purchase right for each share of common stock
outstanding until the rights become detachable. Each right entitles the
registered holder to purchase from the Company one share of common stock for
$15, adjusted for certain events. In the event that the Company is acquired in
a merger or other business combination transaction or more than 50% of its
assets or earning power are sold, each holder shall thereafter have the right
to receive, upon exercise of each right, that number of shares of Common Stock
of the acquiring Company which at the time of such transaction would have a
market value of two times the $15 per share exercise price. The rights will
not be detachable or exercisable until certain events occur. The Board of
Directors may elect to terminate the rights under certain circumstances.
 
 (d) Public Offering
 
  On January 26, 1996, the Company completed a secondary public offering of

fiscal 1993, 1994 and 1995, respectively and approximately $66,000 and
$173,000 for the six months ended March 25, 1995 and March 30, 1996,

(13) LITIGATION
 
  On September 7, 1994, Lunar Corporation (Lunar) filed a complaint in United
States District Court against the Company, alleging, among other things, that
two of the Company's patents are not valid and infringe on three of Lunar's
patents. The Company filed a counterclaim against Lunar with respect to the
infringement of two of the Company's patents and a declaration that certain of
Lunar's patents are invalid and unenforceable.
 
  On November 22, 1995, the Company and Lunar executed a definitive agreement
settling all disputes between the parties. The agreement provides for the
cross-licensing of certain patent rights and continuing payments between the
parties related to future sales. The Company and Lunar have agreed not to
engage each other in patent litigation in the area of x-ray densitometry and
ultrasound for a ten-year period. Management believes that the financial terms
of this agreement will not have a material adverse effect on the Company's
financial position or results of operations.
 
  On January 24, 1995, B.V. Optische Industrie de Oude Delft (Oldelft) filed
suit in the United States District Court against the Company seeking
unspecified treble damages, attorneys' fees and costs relating to a prior
patent dispute between the Company and Oldelft relating to equalization
radiography. On December 14, 1995, the litigation was dismissed by the United
States District Court. Management believes that the outcome of this dispute
will not have a material adverse effect on the Company's financial position or
results of operations.

              REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS
 
To the Board of Directors of FluoroScan Imaging Systems, Inc.:
 
  We have audited the accompanying consolidated balance sheets of FluoroScan
Imaging Systems, Inc. and subsidiary as of December 31, 1994 and 1995, and the
related consolidated statements of income, stockholders' equity, and cash
flows for each of the three years in the period ended December 31, 1995. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.
 
  In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of FluoroScan
Imaging Systems, Inc. and subsidiary at December 31, 1994 and 1995, and the
results of their operations and their cash flows for each of the three years
in the period ended December 31, 1995, in conformity with generally accepted
accounting principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
  (INFORMATION PROVIDED AS OF MARCH 31, 1996 AND THE PERIODS ENDED MARCH 31,
                         1995 AND 1996 ARE UNAUDITED)
 
1. SUMMARY OF ACCOUNTING POLICIES
 
 Operations
 
  The Company is a manufacturer and worldwide distributor of low-intensity,
real-time X-ray imaging devices primarily to health care providers and, to a
lesser extent, to industrial and other users, from its facility in Northbrook,
Illinois.
 
 Consolidation
 
  The consolidated financial statements include the accounts of the Company
and its wholly owned subsidiary, FluoroScan International, Inc., which was
incorporated in November, 1995 and operates a branch in Paris, France. All
significant intercompany balances and transactions have been eliminated.
 
 Interim Financial Statements
 
  The financial information as of March 31, 1996 and with respect to the three
months ended March 31, 1995 and 1996 is unaudited. In the opinion of
management, such information contains all adjustments, consisting only of
normal recurring accruals, necessary for a fair presentation of the results
for such periods.
 
 Estimates
 
  The consolidated financial statements include estimated amounts and
disclosures based on management's assumptions about future events. Actual
results may differ from those estimates.
 
 Cash and Cash Equivalents
 
  The Company considers all highly liquid investments with a maturity of three
months or less to be cash equivalents. Carrying amounts approximate fair value
because of the short-term maturity of instruments.
 
 Concentration of Credit Risk
 
  Financial instruments that potentially subject the Company to significant
concentrations of credit risk consist principally of cash instruments and
trade accounts receivable. The Company maintains cash, cash equivalents, and
short-term investments, primarily invested in treasury bills, with various
financial institutions. The Company provides credit, in the normal course of
business, to national and international health care providers. The Company
performs ongoing credit evaluation of its customers and maintains allowances
for potential credit losses, if necessary. As of December 31, 1995, trade
receivables from the Company's distributor for Canada amounted to $89,380 or
approximately 5% of trade receivables. The entire amount was current. As of
March 31, 1996, trade receivables from the Company's distributor for Germany,
Switzerland, and Austria amounted to $156,726 or 6% of trade receivables. All
amounts were current.
 
 Inventories
 
  Inventories, which principally consist of raw materials and assembled parts,
are stated at the lower of cost or market. Cost is determined using the first-
in, first-out method.
 
 Property, Plant and Equipment
 
  Property, plant and equipment are stated at cost and depreciated over
estimated useful lives of 5 to 7 years, except leasehold improvements which
are amortized over the lesser of the lease term or the useful life of the
 
                                     F-23

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
  (INFORMATION PROVIDED AS OF MARCH 31, 1996 AND THE PERIODS ENDED MARCH 31,
                         1995 AND 1996 ARE UNAUDITED)

property. Straight-line depreciation is used for financial reporting and
amounted to $127,965, $142,786, and $129,360 for 1993, 1994, and 1995,
respectively and $41,609 and $32,898 for the three months ended March 31, 1995
and 1996, respectively. Accelerated methods are used for income tax purposes.
 
 Research and Development
 
  Research and development costs are expensed as incurred. Research and
development costs are included in general and administrative expenses in the
accompanying statements of income and were approximately $298,530 in 1993,
$213,462 in 1994 and $306,110 in 1995 and $68,183 and $78,636 for the three
months ended March 31, 1995 and 1996, respectively.
 
 Advertising
 
  Advertising costs are generally charged to operations in the year incurred
and totaled $17,255 in 1993, $74,547 in 1994, and $198,383 in 1995 and $30,274
and $70,522 for the three months ended March 31, 1995 and 1996, respectively.
 
 Income Taxes
 
  The provision for income taxes includes federal and state income taxes
currently payable and those deferred because of temporary differences between
the financial statement and tax bases of assets and liabilities and the
utilization of net operating losses and tax credit carryovers.
 
 Net Income Per Share
 
  Net income per common share is computed based on the weighted average number
of common shares and common share equivalents outstanding. When dilutive,
stock options and warrants are included as share equivalents using the
treasury stock method.
 
 Reclassifications
 
  Certain reclassifications have been made to prior years to conform to the
presentation used in 1996.
 
2. PROPERTY, PLANT AND EQUIPMENT
 
  Property, plant and equipment consists of the following:

3. ROYALTY AGREEMENTS
 
  (a) The Company is the licensee under two license agreements, covering three
patents, with the United States of America as represented by the National
Aeronautics and Space Administration (NASA). The three patents are the Low
Intensity X-ray Imaging patent (which expires in July 1997), Isolation
Transformer patent and High Voltage Power Supply patent (which both expire in
2002). Under the agreements the Company is required to pay NASA a royalty
equal to 4.5% of sales of the licensed components when all three patents are
used and 3.5% of sales of the licensed components when only the High Voltage
Power Supply and Isolation Transformer patents are used. During 1994, the
Company discontinued using the Low Intensity X-ray Imaging patent. The royalty
payments were further reduced since the components associated with this patent
were of a much higher cost than the components in the other two licensed
inventions. Royalty expense was $94,820, $81,320 and $19,372 for 1993, 1994
and 1995, respectively and $5,952 and $6,594 for the three months ended March
31, 1995 and 1996, respectively. The Company suspended payment of royalties in
1987, in accordance with the agreements, due to the alleged infringement of
one of the licensed patents by three unrelated entities. During 1993, the
Company incurred approximately $146,000 in legal and other costs related to
protecting this patent from infringement. Also during 1993, a $300,000
settlement was reached with two of the alleged infringers and is included in
other income. As part of the settlement, the Company granted one of the
infringers a personal, nonassignable, nontransferable and nonexclusive
sublicense, subject to the payment of royalties. Royalties earned under this
sublicense agreement were $97,625, $154,100 and $204,350 in 1993, 1994 and
1995, respectively and $50,250 and $35,175 for the three months ended March
31, 1995 and 1996, respectively, and are included in other income in the
accompanying consolidated statements of income.
 
  (b) On July 1, 1994, the Company and NASA entered into a settlement relating
to suspended royalties. Pursuant to the terms of the settlement agreement, the
Company paid NASA $79,500 in respect of all suspended royalties through March
28, 1994. Additionally, the Company agreed to timely pay 50% of royalties
incurred after March 28, 1994, with the remaining 50% payable either when the
alleged infringement ceases, when NASA files suit against the alleged
infringer or when the license covering the X-ray and gamma ray imaging device
patent expires in 1997. While payment of royalties was suspended, the Company
continued to accrue royalty expense pursuant to the terms of the agreements.
Therefore, as a result of the settlement agreement the Company realized a
settlement gain of approximately $287,900 in 1994, which was recognized as a
reduction of selling, general and administrative expense in 1994. The Company
has accrued 100% of the royalties incurred after March 28, 1994. Suspended
royalties at December 31, 1994 and 1995, and March 31, 1996 were $42,590,
$58,880, and $62,176 respectively.
 
  (c) Pursuant to a consulting agreement, the Company was previously obligated
to pay to QTR Corporation, whose principals are the inventors of the
technology underlying the NASA patents, a royalty of $300 per FluoroScan
device sold that utilizes QTR Corporation's developments. The royalties
incurred by the Company under the QTR Corporation agreement were $37,200 and
$44,400 for 1993 and 1994, respectively. During the 1994 year, the Company
began to utilize alternative technology and ceased payments to QTR
Corporation.
 
4. LEASES
 
  The Company leases its industrial and office facilities in Northbrook,
Illinois under an operating lease which expires in 1997. The Company is
currently in the process of negotiating an extension to this lease. In 1995,
the Company entered into a three year operating lease agreement for an office
facility in Paris, France. The agreement contains two three-year options,
exercisable at the Company's discretion. Total rent expense for all leases was
$74,289, $78,750 and $103,933 in 1993, 1994 and 1995, respectively and $22,272
and $36,604 for

  No valuation allowances remained at December 31, 1994 or December 31, 1995.
The net change in the valuation allowance for the deferred tax asset was a
decrease of $897,000 and $597,000 for the years ended December 31, 1993 and
1994, respectively, as a result of changes in the Company's assessment of the
realizability of the related deferred tax asset in future years. Other
deferred items consist primarily of temporary differences between the carrying
amount of inventory for financial reporting purposes and the basis used for
income tax purposes.
 
6. STOCKHOLDERS' EQUITY
 
  In July 1994, the Company completed an initial public offering of 1,000,000
units, each unit consisting of one share of common stock at $6.90 per share
and one warrant at $.10 per warrant. Of the 1,000,000 shares of common stock
offered, 565,216 shares were offered by the Company and 434,784 shares were
offered by stockholders. All of the warrants were offered by the Company. In
addition, the Company granted the underwriter an option, which was exercised,
to purchase up to 150,000 units to cover over-allotments. Proceeds to the
Company from the initial offering and over-allotment, after deducting
commissions and offering expenses paid by the Company, were approximately
$4,000,000.
 
  As described above, the Company issued 1,150,000 warrants. The warrants,
which became exercisable in July 1995 and expire in July 1999, have an
exercise price of $7.00 per warrant. The warrants are subject to redemption at
$.01 per warrant, commencing in July 1996, provided that 30 days written
notice has been provided and the closing bid price of the common stock equals
or exceeds $9.00 per share for ten consecutive trading days.
 
  In connection with the offering, the Company agreed to sell to the
underwriter, for nominal consideration, the right to purchase up to an
aggregate of 100,000 units at $10.50 per unit. The right, which is exercisable
for a period of four years commencing in July 1995, grants the holder certain
piggyback and demand rights with respect to registration under the Securities
Act.
 
  Stock Split and Stock Dividend--On April 15, 1994, the Board of Directors
declared a 1,344-for-1 stock split which became effective on April 22, 1994.
On June 24, 1994 the Company effected a 17.6% stock dividend. All share and
per share data has been restated to reflect the stock split and dividend.
 
  Stock Incentive Plans--The Company has two stock incentive plans, both of
which are active. In April 1994, the Company adopted a stock option plan (the
"1994 Plan") and in June 1995 the Company's stockholders approved a separate
stock option plan (the "1995 Plan"). Both plans provide for the issuance of
incentive stock options at a purchase price approximating the fair market
value of the Company's common shares at the date of the grant (or 110% of such
fair market value in the case of substantial stockholders). The 1994 and 1995
Plans

Board of Directors approved the establishment of a stock option plan for non-
employee directors and the granting to the current non-employee directors of
options to purchase an aggregate of 30,000 shares at an exercise price equal
to the fair market value of the common stock on August 20, 1994, all subject
to stockholder approval. In December 1994, the employee directors on the Board
of Directors adopted the 1994 Directors Stock Option Plan, subject to approval
by the stockholders at the 1995 Annual Meeting. Such approval was obtained in
June, 1995. A total of 600,000 shares of the Company's common stock have been
reserved pursuant to such plan. The following table provides summary

                          AGREEMENT AND PLAN OF MERGER

   AGREEMENT entered into as of the 18th day of July, 1996, by and among
Hologic, Inc., a Delaware corporation, with its principal place of business in
Waltham, Massachusetts (the "Parent"), Fenway Acquisition Corp., a Delaware
corporation and wholly owned subsidiary of the Parent, with its principal place
of business in Waltham, Massachusetts (the "Acquisition Subsidiary"), and
FluoroScan Imaging Systems, Inc., a Delaware corporation, with its principal
place of business in Northbrook, Illinois ("the Company").  The Parent, the
Acquisition Subsidiary and the Company are referred to collectively herein as
the "Parties"

   WHEREAS, the Parties have agreed that it is in their best interests for the
Acquisition Subsidiary to merge with and into the Company upon the terms and
conditions set forth herein.  The Boards of Directors of the Acquisition
Subsidiary and the Company have approved the merger of their respective
companies and have recommended to the respective stockholders of the Acquisition
Subsidiary and the Company that they approve the merger and this Agreement.

   WHEREAS, this Agreement contemplates a tax-free merger of the Acquisition
Subsidiary with and into the Company.  In such merger, the stockholders of the
Company will receive capital stock of the Parent in exchange for their capital
stock of the Company and thereby continue to participate in the equity and
appreciation of the combined enterprise.

   NOW, THEREFORE, in consideration of the mutual agreements herein contained,
the Parties hereto agree as follows:

                                   ARTICLE I

           ----------                                                       
Agreement, the Acquisition Subsidiary shall merge with and into the Company
(with such merger referred to herein as the "Merger") at the Effective Time (as
defined below).  From and after the Effective Time, the separate corporate
existence of the Acquisition Subsidiary shall cease and the Company shall
continue as the surviving corporation in the Merger (the "Surviving
Corporation").  The "Effective Time" shall be the time at which the Company and
the Acquisition Subsidiary file a certificate of merger in substantially the
form attached hereto as Exhibit A (the "Certificate of Merger") in accordance
                        ---------                                            
with the relevant provisions of the Delaware General Corporation Law ("DGCL"),
with the Secretary of State of the State of Delaware.  The Merger shall have the
effects set forth in Section 251 and 259 of the DGCL.

    1.2    The Closing.  The closing of the transactions contemplated by this
           -----------                                                       
Agreement (the "Closing") shall take place at the offices of Brown, Rudnick,
Freed & Gesmer in Boston, Massachusetts, commencing at 9:00 a.m. local time on
the second business day after the receipt of Requisite Stockholder Approval (as

mutually 


                                      A-1
<PAGE>
 
agreeable later date as soon as practicable after the satisfaction or
waiver of all conditions to the obligations of the Parties to consummate the
transactions contemplated hereby (the "Closing Date"); provided, however, that
the Closing Date shall be no later than November 30, 1996.

    1.3    Actions at the Closing.  At the Closing, subject to the satisfaction
           ----------------------                                              
or waiver of all of the Conditions set forth in Article 5, not theretofor
satisfied or waived, (a) the Company and the Acquisition Subsidiary shall file
with the Secretary of State of the State of Delaware the Certificate of Merger
and (b) the Parent shall deliver a certificate for the Merger Shares (as defined
below) to American Stock Transfer & Trust Company or other entity reasonably
satisfactory to the Company appointed by the Parent to act as the exchange agent
(the "Exchange Agent") in accordance with Section 1.7.

    1.4    Additional Actions.  The Surviving Corporation may, at any time after
           ------------------                                                   
the Effective Time, take any action, including executing and delivering any
document, in the name and on behalf of either the Company or the Acquisition
Subsidiary, in order to consummate the transactions contemplated by this
Agreement.

    1.5    Conversion of Shares.  At the Effective Time, by virtue of the Merger
           --------------------                                                 
and without any action on the part of any Party or the holder of any of the
following securities:

          (a) Each share of common stock, $.0001 par value per share, of the
Company ("Company Shares") issued and outstanding immediately prior to the
Effective Time (other than Company Shares owned by the Parent or the Acquisition
Subsidiary and Company Shares held in the Company's treasury) shall be converted
into and represent the right to receive such number of shares of common stock,
$.01 par value per share, of the Parent ("Parent Common Stock") as is equal to
the Conversion Ratio.  The "Conversion Ratio" shall be .31069; provided,
                                                               -------- 
however, that if the Average Market Value (as hereinafter defined) of the Parent
- -------                                                                         
Common Stock is greater than $50.29, the Conversion Ratio shall equal $15.63
divided by the Average Market Value; and provided, further, that if the Average
                                         --------  -------                     
Market Value of the Parent Common Stock is less than $30.17, and the Parent so
elects on a timely basis as set forth in Section 6.3(iii) (a "Parent Adjustment
Election"), the conversion ratio shall equal $9.37 divided by the Average Market
Value.  If the Average Market Value of the Parent Common Stock is less than
$30.17 and Parent does not make a Parent Adjustment Election, the Conversion
Ratio shall continue to be .31069, subject to the Company's right to terminate
this Agreement as set forth herein.  For purposes hereof, the term "Average
Market Value" means the arithmetic average (rounded to the nearest five decimal
places) of the closing price per share of the Parent Common Stock as reported on
the Nasdaq National Market for the ten (10) consecutive trading days ending two
trading days prior to the Closing.  Holders of Company Shares shall also have
the right to receive together with each share of Parent Common Stock issued in
the Merger pursuant to this Section 1.5(a), an associated common stock purchase
right ("Parent Purchase Right") pursuant to the Rights Agreement dated as of
December 22, 1992, as amended, between the Parent and the Rights Agent named
therein.  References herein to Parent Common Stock issuable in the Merger shall
be deemed to include the associated Parent Purchase Rights.

                                      A-2

<PAGE>
 
    The Conversion Ratio shall at all times be rounded to the nearest fifth
decimal place.  The Conversion Ratio shall be subject to equitable adjustment in
the event of any stock split, stock dividend, reverse stock split,
reorganization, recapitalization or similar event affecting the Parent Common
Stock between the date of this Agreement and the Effective Time.  Stockholders
of record of the Company as of the Effective Time ("Company Stockholders") shall
be entitled to receive immediately all of the shares of Parent Common Stock into
which their Company Shares were converted pursuant to this Section 1.5(a) (the
"Merger Shares").

          (b) No certificates or scrip representing fractional Merger Shares
shall be issued to former Company Stockholders upon the surrender for exchange
of Certificates (as defined below), and such former Company Stockholders shall
not be entitled to any voting rights, rights to receive any dividends or
distributions or other rights as a stockholder of the Parent with respect to any
fractional Merger Shares that would otherwise be issued to such former Company
Stockholders.  In lieu of any fractional Merger Shares that would otherwise be
issued, each former Company Stockholder that would have been entitled to receive
a fractional Merger Share shall, upon proper surrender of such person's
Certificates representing such fractional Merger Shares, receive cash in an
amount equal to such fractional Merger Share multiplied by the Conversion Ratio
times the Average Market Value.  The Merger Shares and the cash to be received
in lieu of fractional Merger Shares are collectively referred to herein as the
"Merger Consideration."

          (c) Each Company Share held in the Company's treasury immediately
prior to the Effective Time and each Company Share owned by the Parent or the
Acquisition Subsidiary shall be canceled and retired without payment of any
consideration therefor.

          (d) Each share of common stock, $.01 par value per share, of the
Acquisition Subsidiary issued and outstanding immediately prior to the Effective
Time shall be converted into and thereafter evidence one share of common stock,
$.01 par value per share, of the Surviving Corporation.

    1.6    No Appraisal Rights.  This Agreement provides that the Company
           -------------------                                           
Stockholders shall be entitled to notice of the Special Meeting (as defined in
Section 4.3 below).  The Company Shares are designated as Nasdaq National Market
securities and the Parent Common Stock is designated as a Nasdaq National Market
security and is contemplated to be so designated at the record date for the
Special Meeting.  Therefore, in accordance with Section 262 of the DGCL, no
Company Stockholder shall be entitled to appraisal rights.

    1.7    Exchange of Shares.
           ------------------ 

          (a) Prior to the Effective Time, the Parent shall appoint the Exchange
Agent (or such other Exchange Agent as the parties shall mutually agree) to
effect the exchange for the Merger Consideration of Certificates that,
immediately prior to the Effective Time, represented Company Shares converted
into Merger Shares pursuant to Section 1.5 ("Certificates").  On or before the
Closing Date, the Parent shall deliver to the Exchange Agent, in trust for the
benefit of holders of Certificates, a stock certificate (issued in the name of
the Exchange Agent or its

                                      A-3

<PAGE>
 
nominee) representing Merger Shares, as described in Section 1.5(a) and
sufficient funds to make cash payments in lieu of fractional Merger Shares, as
described in Section 1.5(b). As soon as practicable after the Effective Time,
the Parent shall cause the Exchange Agent to send a notice and a transmittal
form to each holder of a Certificate (other than those surrendered and paid for
at the Closing) advising such holder of the effectiveness of the Merger and the
procedure for surrendering to the Exchange Agent such Certificate in exchange
for the Merger Consideration. Each holder of a Certificate, upon proper
surrender thereof to the Exchange Agent in accordance with the instructions in
such notice, shall be entitled to receive in exchange therefor (subject to any
taxes required to be withheld) the Merger Consideration, without interest,
determined pursuant to Sections 1.5(a) and (b). Until properly surrendered, each
such Certificate shall be deemed for all purposes to evidence only the right to
receive the Merger Consideration determined pursuant to Sections 1.5(a) and (b).
Holders of Certificates shall not be entitled to receive certificates for the
Merger Shares or cash payments to which they would otherwise be entitled until
such Certificates are properly surrendered.

          (b) If any Merger Consideration is to be issued or paid in the name of
a person other than the person in whose name the Certificate surrendered in
exchange therefor is registered, it shall be a condition to the issuance and
payment of such Merger Consideration that (i) the Certificate so surrendered
shall be transferable, and shall be properly assigned, endorsed or accompanied
by appropriate stock powers, (ii) such transfer shall otherwise be proper and
(iii) the person requesting such transfer shall pay to the Exchange Agent any
transfer or other taxes payable by reason of the foregoing or establish to the
satisfaction of the Exchange Agent that such taxes have been paid or are not
required to be paid.  Notwithstanding the foregoing, neither the Exchange Agent
nor any Party shall be liable to a holder of Company Shares for any Merger
Shares issuable to such holder pursuant to Section 1.5(a) that are delivered to
a public official in accordance with applicable abandoned property, escheat or
similar laws.

          (c) In the event any Certificate shall have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the person claiming
such Certificate to be lost, stolen or destroyed, the Parent shall direct the
Exchange Agent to issue in exchange for such lost, stolen or destroyed
Certificate the Merger Shares issuable in exchange therefor pursuant to Section
1.5(a) and to make any cash payment in lieu of a fractional Merger Share
pursuant to Section 1.5(b).  The Board of Directors of the Parent may, in its
discretion and as a condition precedent to the issuance thereof, require the
owner of such lost, stolen or destroyed Certificate to give the Parent a bond in
such sum as it may direct as indemnity against any claim that may be made
against the Parent with respect to the Certificate alleged to have been lost,
stolen or destroyed.

          (d) The Exchange Agent shall invest the cash portion of the Merger
Consideration as directed by the Parent; provided, however, that all risk of
loss related to such investments shall be borne by the Parent.

          (e) Promptly following the date which is six months after the Closing
Date, the Exchange Agent shall return to the Parent all Merger Consideration
(including the proceeds of any investments thereof) in its possession, and the
Exchange Agent's duties shall terminate. 

                                      A-4

<PAGE>
 
Thereafter, each holder of a Certificate may surrender such Certificate to the
Parent and, subject to applicable abandoned property, escheat and similar laws,
receive in exchange therefor the Merger Consideration, without interest,
issuable with respect thereto pursuant to Sections 1.5(a) and (b).

    1.8    Dividends.  No dividends or other distributions that are payable to
           ---------                                                          
the holders of record of Parent Common Stock as of a date on or after the
Effective Time shall be paid to former Company Stockholders entitled by reason
of the Merger to receive Merger Shares until such holders surrender their
Certificates in accordance with Section 1.7.  Upon such surrender, the Parent
shall pay or deliver to the persons in whose name the certificates representing
such Merger Shares are issued any dividends or other distributions that are
payable to the holders of record of Parent Common Stock as of a date on or after
the Effective Time and which were paid or delivered between the Effective Time
and the time of such surrender provided that no such person shall be entitled
receive any interest on such dividends or other distributions.

    1.9    Options and Warrants.
           -------------------- 

          (a) As of the Effective Time, all (i) options to purchase Company
Shares issued by the Company pursuant to its stock option plans or otherwise
("Options"), whether vested or unvested, and  (ii) options to purchase Company
units, each unit ("Unit") consisting of one share of Common Stock and a warrant
to purchase one share of Common Stock ("Unit Options"), whether or not
exercisable, shall be assumed by the Parent.  Immediately after the Effective
Time, each Option and Unit Option outstanding immediately prior to the Effective
Time shall be deemed to constitute an option or warrant to acquire, on the same
terms and conditions as were applicable under such Option or Unit Option at the
Effective Time (without giving effect to the Merger), such number of shares of
Parent Common Stock and warrants to purchase shares of Parent Common Stock is
equal to the number of Company Shares and warrants to purchase Company Shares
subject to the unexercised portion of such Option or Unit Option multiplied by
the Conversion Ratio (except as otherwise provided in the applicable instrument,
with any fraction resulting from such multiplication to be paid in cash upon the
exercise of such Option or Unit Option based upon the closing price of Parent
Common Stock on the Nasdaq National Market on the date of exercise).  The
exercise price per share of each such assumed Option and Unit Option shall be
equal to the exercise price of such Option or Unit Option immediately prior to
the Effective Time, divided by the Conversion Ratio.  The terms, exercisability,
vesting schedule, status as an "incentive stock option" under Section 422 of the
Internal Revenue Code of 1986 (as amended, the "Code"), if applicable, and all
of the other terms of the Options and Unit Options shall otherwise remain
unchanged.  Without limiting the foregoing, for purposes of determining vesting
of the Options and otherwise, employees of the Company will be credited for
their full term during which they were employed by the Company.

          (b) As soon as practicable after the Effective Time, the Parent or the
Surviving Corporation shall deliver to the holders of Options and Unit Options
appropriate notices setting forth such holders' rights pursuant to such Options
or Unit Options, as amended by this Section 1.9, and the agreements evidencing
such Options or Unit Options shall continue

                                      A-5

<PAGE>
 
in effect on the same terms and conditions (subject to the amendments provided
for in this Section 1.9 and such notice).

          (c) The Parent shall take all corporate action necessary to reserve
for issuance a sufficient number of shares of Parent Common Stock for delivery
upon exercise of the Options and Unit Options, including the warrants
thereunder, assumed in accordance with this Section 1.9.  As soon as practicable
after the Effective Time, and in any event within thirty (30) days thereafter,
the Parent shall file a Registration Statement on Form S-8 (or any successor
form) under the Securities Act of 1933, as amended (the "Securities Act") with
respect to all shares of Parent Common Stock subject to Options that may be
registered on a Form S-8, and shall use commercially reasonable efforts to
maintain the effectiveness of such Registration Statement for so long as such
Options remain outstanding.

          (d) The Company shall use commercially reasonable efforts to obtain,
prior to the Closing, the consent from each holder of an Option or Unit Option
to the amendment of such Option or Unit Option pursuant to this Section 1.9
(unless such consent is not required under the terms of the applicable
agreement, instrument or plan).

    1.10   Certificate of Incorporation.  The Certificate of Incorporation of
           ----------------------------                                      
the Surviving Corporation shall be the Certificate of Incorporation of the
Company as amended and restated in the Certificate of Merger.

    1.11   Bylaws.  The Bylaws of the Surviving Corporation shall be the same as
           ------                                                               
the Bylaws of the Acquisition Subsidiary immediately prior to the Effective
Time, except that the name of the corporation set forth therein shall be changed
to the name of the Company.

    1.12   Directors and Officers.  The directors of the Acquisition Subsidiary
           ----------------------                                              
shall become the directors of the Surviving Corporation as of the Effective
Time.  Promptly after the Effective Time, the board of directors of the
Surviving Corporation shall be expanded to a number not to exceed five and Larry
S. Grossman and Arlen L. Issette shall be elected to the Board.  The officers of
the Company at the Effective Time shall remain as officers of the Surviving
Corporation after the Effective Time, retaining their respective positions.

    1.13   No Further Rights.  From and after the Effective Time, no Company
           -----------------                                                
Shares shall be deemed to be outstanding, and holders of Certificates shall
cease to have any rights with respect thereto, other than the right to receive
Merger Shares or cash in lieu thereof under Sections 1.5(a) and (b) or as
otherwise provided herein or by law.

    1.14   Closing of Transfer Books.  At the Effective Time, the stock transfer
           -------------------------                                            
books of the Company shall be closed and no transfer of Company Shares shall
thereafter be made.  If, after the Effective Time, Certificates are presented to
the Surviving Corporation, the Parent or the Exchange Agent, they shall be
canceled and exchanged for Merger Consideration in accordance with Sections
1.5(a) and (b).

to do business and in good standing as a foreign corporation in Illinois and
Michigan and it is not required to be licensed or qualified to conduct its
business or own its property in any other jurisdiction, except where the failure
to be so licensed or qualified would not, individually or in the aggregate, have
a material adverse effect on the business, properties, operations, prospectus,
assets, revenues or condition (financial or otherwise) of the Company and its
Subsidiaries (as defined below) on a consolidated basis (a "Company Material
Adverse Effect").

    2.2    Capitalization . The authorized capital stock of the Company consists
           --------------

Unit Options and the warrants included in the Units, upon issuance in accordance
with the terms and conditions specified in the instruments pursuant to which
they are issuable and upon payment therefor, will be duly authorized and validly

number of Company Shares subject to each instrument) and the Company' Redeemable
Common Stock Warrants (all of which warrants shall be redeemed or exercised as
of the Effective Time), there are no (i) outstanding or authorized
subscriptions, warrants, options or other rights granted by the Company or
binding upon the Company to purchase or acquire, or preemptive rights with
respect to the issuance or sale of, the capital stock of the Company or which
obligate or may obligate the Company to issue any additional shares of its
capital stock or any securities convertible into or evidencing the right to
subscribe for any shares of its capital stock, (ii) other securities of the

                                      A-7

identifies each holder of Options and Warrants, which Options or Warrants (x) do
not by their terms require the holder to accept the assumption by the Parent of
such Options or Warrants pursuant to Section 1.9(a) hereof, or (y) contain terms
and conditions that would result in acceleration of the vesting schedule or
exercise period set forth therein upon the consummation of the Merger.

    2.3    Subsidiaries.  Schedule 2.3 of the Company Disclosure Schedule sets
           ------------   ------------

outstanding shares of each class of its capital stock, the names of the holders
thereof and the number of shares held by each such holder, (d) the number of

Subsidiary is duly qualified to conduct business and is in good standing under
the laws of each jurisdiction in which the nature of its businesses or the
ownership or leasing of its properties requires such qualification, except where
the failure to so qualify would not, individually or in the aggregate, have a
Company Material Adverse Effect.  Each Subsidiary has all requisite corporate
power and authority to carry on the businesses in which it is engaged and to own
and use the properties owned and used by it.  The Company has delivered to the
Parent correct and complete copies of the Charter and Bylaws of each Subsidiary,
as amended to date.  All of the issued and outstanding shares of capital stock
of each Subsidiary are duly authorized and validly issued, fully paid,
nonassessable and free of preemptive rights.  All shares of each Subsidiary that
are held of record or owned beneficially by either the Company or any Subsidiary
are held or owned free and clear of any restrictions on transfer (other than
restrictions under the Securities Act and state securities laws), claims,
security interests, options, warrants, rights, contracts, calls, commitments,
equities and demands.  There are no outstanding or authorized options, warrants,
rights, agreements or commitments to which the Company or any Subsidiary is a
party or which are binding on any of them providing for the issuance,
disposition or acquisition of any capital stock of any Subsidiary.  There are no
outstanding stock appreciation, phantom stock or similar rights with respect to
any Subsidiary.  There are no voting trusts, proxies, or other agreements or
understandings with respect to the voting of any capital stock of any
Subsidiary.  No Subsidiary is in default under or in violation of any provision
of its Charter or Bylaws.  The Company does not control directly or indirectly
or have any direct or indirect equity participation in any corporation,
partnership, trust, or other business association which is not a Subsidiary.

    2.4    Authorization of Transaction.  The Company has all requisite power
           ----------------------------

approval of the Merger by a majority of the votes represented by the outstanding
Company Shares entitled to vote on this Agreement and the Merger (the "Requisite
Stockholder Approval"), the performance by the Company of this Agreement and the

of Parent, threatened) against Parent or any of its subsidiaries, and there are
no outstanding court orders, court decrees, or court stipulations to which
Parent or any of its subsidiaries is a party or by which any of their respective

transactions contemplated hereby, or (b) materially restrict the present
business, properties, operations, prospects, assets or condition, financial or
otherwise, of Parent, or (c) would, individually or in the aggregate have a
Parent Material Adverse Effect or materially impair or preclude the Parent's or
the Acquisition Subsidiary's ability to consummate the Merger or the other
transactions contemplated hereby.  Parent has no reason to believe that any such
claim, action, suit, arbitration, proceeding or investigation may be brought

written notice of any event or development that would (a) render any statement,
representation or warranty of the Company in this Agreement (including the
Company Disclosure Schedule) inaccurate or incomplete in any material respect,
or (b) constitute or result in a breach by the 


                                     A-35

<PAGE>
 
Company of, or a failure by the Company to comply with, any agreement or
covenant in this Agreement applicable to such Party. The Parent or the
Acquisition Subsidiary shall promptly deliver to the Company written notice of
any event or development that would (i) render any statement, representation or
warranty of the Parent or the Acquisition Subsidiary in this Agreement
inaccurate or incomplete in any material respect, or (ii) constitute or result
in a breach by the Parent or the Acquisition Subsidiary of, or a failure by the
Parent or the Acquisition Subsidiary to comply with, any agreement or covenant
in this Agreement applicable to such Party. No such disclosure shall be deemed
to avoid or cure any such misrepresentation or breach.

           ----------- 

          (a)  The Company shall not, and the Company shall use commercially
reasonable efforts to cause each of its officers, directors, employees,
representatives and agents not to, directly or indirectly, (a) encourage,
solicit, initiate, engage or participate in discussions or negotiations with any
person or entity (other than the Parent) concerning any merger, consolidation,
sale of material assets, tender offer, recapitalization, accumulation of Company
Shares, proxy solicitation or other business combination involving the Company,
any Subsidiary or any division of the Company or any Subsidiary (an "Acquisition
Transaction") or (b) provide any information concerning the business, properties
or assets of the Company or any Subsidiary to any person or entity (other than
the Parent).

    
          (b) Anything herein to the contrary notwithstanding, in the event the
Company receives an unsolicited written proposal for, or an unsolicited written
indication of a serious interest in entering into, an Acquisition Transaction
from a bona fide, financially capable third party that contains no financing
contingency, (i) the Company in its discretion may furnish to and communicate
with such third party public information requested by such party, and (ii) the
Company may enter into discussions and negotiations with such third party and
may, at the request of such third party, furnish such third party with non-
public information concerning the Company, provided (in the case of this clause
(ii)) that (A) the Company gives the Buyer written notice thereof at least five
(5) business days prior to furnishing any such information, (B) the Company's
Board of Directors, after consultation with and based upon the advice of an
independent financial advisor (who may be the Company's regularly engaged
financial advisor), determines in good faith that such third party is
financially capable, without any financing contingency, of consummating an
Acquisition Transaction that would yield a higher value to the Company
Stockholders than will the Merger, (C) the Company's Board of Directors, after
weighing such advice, determines that taking such action is more likely than not
to lead to an Acquisition Transaction with such third party that would yield a
higher value to the Company Stockholders than will the Merger, and (D) the
Company's Board of Directors shall have been advised in writing by independent
legal counsel (who may be the Company's regular legal counsel), that any failure
to provide such non-public information to such party would likely constitute a
breach of the fiduciary responsibilities of the Board of Directors to the
Company Stockholders.

          --------------------------                                           
Merger may be abandoned at any time prior to the Effective Time, before or after

the Company, if:

          (i)  the Parent or the Acquisition Subsidiary shall have failed to
comply in any material respect with any of the covenants or agreements contained
in Articles I and IV of this Agreement to be complied with or performed by the
Parent or the Acquisition Subsidiary at or prior to such date or termination;
provided, however, that if such failure or failures are capable of being cured
prior to the Effective Time, such failure, or failures shall not have been cured
within fifteen (15) days of delivery to the Parent of written notice of such
failure or failures

         (ii)  there exists a breach or breaches of any representation or

     6.5  Effect of Termination and Abandonment.
          ------------------------------------- 

          (a) In the event of termination of this Agreement and abandonment of
the Merger pursuant to this Article VI, no Party hereto (or any of its directors
or officers) shall have any liability or further obligation to any other Party
to this Agreement, except as provided in Section 4.5 (regarding confidentiality)
and this Section 6.5 and except that nothing herein shall relieve any Party from
liability for any breach of this Agreement.

          (b) In the event of:  (i) a termination of this Agreement pursuant to
Section 6.1(iv), or (ii) any termination of this Agreement by the Parent
pursuant to Section 6.2, then the Company shall promptly pay the Parent by wire
transfer of immediately available funds to an account specified by the Parent up
to $1.5 million for all documented fees and expenses incurred by the Parent
(including the reasonable fees and expenses of counsel, accountants, consultants
and advisors) in connection with this Agreement and the transactions
contemplated hereby (subject to such $1.5 million limit, "Parent Documented
Expenses").  In the event of a termination of this Agreement pursuant to Section
6.1(iv), where the Board of Directors of the Company withdraws its
recommendation of the Merger or modifies such recommendation in a manner adverse
to the Parent,  or Section 6.2(iii), the Company shall promptly pay the Parent
by wire transfer of immediately available funds to an account specified by the
Parent an additional fee of $2.4 million (the "Break-up Fee").  To the extent
that either the Parent Documented Expenses or the Break-up Fee have not already
become payable and been paid, and, if prior to any termination pursuant to
Section 6.1(i), (ii), (iii) or (iv) or Section 6.2(i), (ii) or (iii), any person
shall have made a bona fide proposal concerning a Business Combination
Transaction and prior to or within twelve (12) months after the termination of
this Agreement the Company or any of its Subsidiaries, or any Company Affiliate
enters into a definitive agreement with a third party with respect to a Business
Combination Transaction or a Business Combination Transaction is effected, then
the Company, prior to entering into any such definitive agreement or any such
Business Combination Transaction being effected, shall promptly pay the Parent
by wire transfer of immediately available funds to an account specified by the
Parent the Parent Documented Expenses and the Break-up Fee.  As used in this
Section 6.5, the term "Business Combination Transaction" shall mean any of the
following involving the Company or any Subsidiary, that is material to the
business, results of operation, prospects or financial condition of the Company
and its Subsidiaries taken as whole:  (1) any merger, consolidation, share
exchange, business combination or other similar transaction (other than the
Merger); (2) any sale, lease, exchange, transfer or other disposition of 50% or
more of the assets of the Company and its Subsidiaries, taken as a whole, in a
single transaction or series of transactions; or (3) the acquisition by a person
or entity, or any "group" (as such term is defined under Section 13(d) of the
Exchange Act and the rules and regulations thereunder) of beneficial ownership
of 33 1/3% or more of the Company Shares, whether by tender offer, exchange
offer or otherwise.

          (c) In the event of a termination of this Agreement by the Company,
pursuant to Section 6.3, (i) or (ii) then the Parent shall promptly pay the
Company by wire transfer of immediately available funds to an account specified
by the Company up to $1.5 million for all documented fees and expenses incurred
by the Company (including the reasonable

                                      A-44

<PAGE>
 
fees and expenses of counsel, accountants, consultants and advisors) in
connection with this Agreement and the transactions contemplated hereby.

                                 MISCELLANEOUS

           -----------------                                                 
and the Company shall bear their respective expenses, in each case, in
connection with the negotiation and the consummation of the transactions
contemplated by this Agreement; provided, however, that if the Merger is
consummated, the Company and the Subsidiaries shall not incur more than $1.5
million in legal, accounting and investment banking fees and expenses in
connection with the Merger, without the consent of the Parent, which shall not
be unreasonably withheld.

    7.2    Notices.  Any notice or other communication in connection with this

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

written consent of the other parties; provided, however, that any Party may make

(in which case the disclosing Party shall advise the other Parties and provide
them with a copy of the proposed disclosure prior to making the disclosure).

    7.4    Entire Agreement.  This Agreement (including all exhibits or
           ----------------

reference to the subject matter hereof and inducements to the making of this
Agreement relied upon by any party hereto, have been expressed herein or in the
documents incorporated herein by reference.

    7.5    Severability.  The invalidity or unenforceability of any provision of
           ------------

           -------------                                                       
operation of law (a) by the Parent or the Acquisition Subsidiary without the
prior written consent of the Company or (b) by the Company without the prior
written consent of the Parent.  However, any or all rights of the Parent to
receive performance (but not the obligations of the Parent to Company hereunder)
and rights to assert claims against the Company or the Company Stockholders or
in respect of breaches of representations, warranties or covenants of the

                                      A-46

<PAGE>
 
Company hereunder, may be assigned by the Parent to (i) any direct or indirect
subsidiary, parent or other affiliate of the Parent, or (ii) any purchaser of
all or substantially all of the assets or business of the Parent after Closing
subject to such assignee's assumption of all of the Parent's obligations

of this Agreement at any time prior to the Effective Time with the prior

any amendment effected subsequent to the Requisite Stockholder Approval shall be
subject to the restrictions contained in the DGCL.  No amendment of any
provision of this Agreement shall be valid unless the same shall be in writing
and signed by all of the Parties.  No waiver by any Party of any default,
misrepresentation, or breach of warranty or covenant hereunder, whether
intentional or not, shall be deemed to extend to any prior or subsequent
default, misrepresentation, or breach of warranty or covenant hereunder or
affect in any way any rights arising by virtue of any prior or subsequent such
occurrence.

    7.8    Governing Law; Venue.
           -------------------- 

          (a) This Agreement shall be governed by and construed in accordance
with the laws of the State of Delaware (other than the choice of law principles
thereof), except that any representations and warranties with respect to real
and tangible property shall be governed by and construed in accordance with the
laws of the jurisdiction where such property is situated if other than in the
State of Delaware.

          (b) Any claim, action, suit or other proceeding initiated by any
Party, under or in connection with this Agreement may be asserted, brought,
prosecuted and maintained in any Federal or state court in the State of
Delaware, as the Party bringing such action, suit or proceeding shall elect,
having jurisdiction over the subject matter thereof, and the Parties hereby
waive any and all rights to object to the laying of venue in any such court and
to any right to claim that any such court may be an inconvenient forum. Each of
the Parties hereby submit themselves to the jurisdiction of each such court and
agree that service of process on them in any such action, suit or proceeding may
be effected by the means by which notices are to be given to it under this
Agreement.

    7.9   Remedies.  The Parties hereto acknowledge that the remedy at law for
          --------                                                            
any breach of the obligations undertaken by the Parties hereto is and will be
insufficient and inadequate and that the Parties hereto shall be entitled to
equitable relief, in addition to remedies at law.  In the event of any action to
enforce the provisions of this Agreement, each of the Parties shall waive the
defense that there is an adequate remedy at law.  Without limiting any remedies
the Parties may otherwise have hereunder or under applicable law, in the event
any Party refuses to perform its obligations under this Agreement, the other
Parties shall have, in addition to any other rights at law or equity, the right
to specific performance.

of the Company Stockholders, (b) the provisions in Sections 4.10 concerning
insurance and indemnification are intended for the benefit of the individuals
specified therein and their respective legal representatives, and (c) the

warranties of Parent, the Acquisition Subsidiary and the Company contained
herein or in any certificates or other documents delivered prior to or at the
Closing shall not be deemed waived or otherwise affected by any investigation
made by any party hereto and shall not survive the Closing.  Representations and
warranties to a party's knowledge shall mean such party shall have made due
inquiry and investigation.  Nothing herein shall relieve any party for liability
for fraud in connection with any representation or warranty made hereunder.

     NOW, THEREFORE, in consideration of the foregoing, the mutual covenants and
agreements contained herein and other valuable consideration, the receipt and

to liability for the sale of his Parent Common Stock acquired upon the Parent's
exercise of this Option pursuant to Section 16(b) of the Securities Exchange Act
of 1934 and the rules and regulations promulgated thereunder, Parent shall not
register such shares until the applicable holding period has expired and shall
promptly after request by a stockholder, loan such funds to such Stockholder as
are necessary and appropriate to pay income taxes (Federal and state, including
estimated taxes) with respect to the receipt of the Parent Common Stock upon
exercise by Parent of this Option, but reduced by any cash received by a
Stockholder in connection with such exercise, subject to the right of Parent to
secure the repayment of such loan pursuant to the pledge of such Parent Common
Stock and the obligation of the Stockholders to repay the loans upon sale of the
Parent Common Stock, but in no event later than the earlier of sixty (60) days
after (a) the effective date of the Registration Statement, or (b) the date the
shares first become saleable under Rule 144 under the Securities Act (including
any successor rule, "Rule 144"); provided that prior to being required to make
such loan to a Stockholder, the Stockholder must execute such instruments and
agreements evidencing its obligations pursuant thereto and the required pledge,
in form and substance reasonably satisfactory to Parent.  Such loans shall be
nonrecourse loans secured only by the Buyer Common Stock.

     5.3  Price Protection.  Parent agrees that for any shares of Parent Common
          ----------------                                                     
Stock issued to a Stockholder in connection with the Parent's exercise of this
Option, Parent will guarantee that the purchase price received by the
Stockholder for the sale of such Parent Common Stock will be no less than 85%
times the Average Market Value with respect to all sales of such Parent Common
Stock made within sixty (60) days of the date that such shares are saleable,
whether pursuant to an effective Registration Statement or pursuant to Rule 144,
and provided, further, that the Stockholder sells the shares through a broker
designated by Parent.  In the event that such sale yields gross proceeds of less
than the Average Market Value of such shares (calculated as set forth herein),
the Parent will promptly reimburse the Stockholder for such shortfall.

Agreement between him and the Company dated February 15, 1994 (the "Existing
Employment Agreement"); and

    WHEREAS, Employee will receive substantial economic benefit as a result of
the Merger; and

    WHEREAS, during the course of Employee's affiliation with the Company, the
Employee has become experienced in all aspects of the business of the Company,
and the growth and success of the business of the Company and the development of
a market for the Company's products has been due in large part to the services
and unique talents of the Employee; and

    WHEREAS, in order to assure itself of the continued benefits to be obtained
from the special talents and abilities of Employee, the Company desires to

    NOW, THEREFORE, in consideration of the Merger Agreement and the mutual
covenants and promises therein and herein contained, the receipt and sufficiency
of which is acknowledged, and intending to be legally bound, it is hereby agreed
by and between the parties as follows:

    1     Employment; Board of Directors.
          ------------------------------ 

    (a)   Subject to the terms and conditions of this Agreement, during the Term
(as hereinafter defined) of this Agreement (i) the Company hereby employs
Employee as the Chairman of the Board and Chief Executive Officer of the
Company, and (ii) Hologic hereby employs Employee as a Vice President of
Hologic.  Employee, together with Arlen L. Issette (unless Mr. Issette is no
longer employed by the Company), shall have general management of the day-to-day
business of the Company in the ordinary course of business and such powers as
may be reasonably incident to such responsibilities, subject in all instances to
the general supervision and direction of the Chairman of the Board and President
of Hologic,  and the Board of Directors of the Company.  Employee shall have
such executive duties as an officer of Hologic, consistent with the Company's
past practice,  as the Board of Directors of Hologic shall determine from time
to time.  Employee hereby accepts such employment.

    (b)   On or promptly after the Effective Date (as hereinafter defined)
Hologic in its capacity as the sole stockholder of the Company shall cause
Employee to be elected to the Board of Directors of the Company.

    (c)   Effective as of the Effective Date, the number of members constituting
Hologic's Board of Directors shall be increased by one (1) and Employee shall
become a member of such Board of Directors and the Company's Board of Directors.
Employee shall serve as a member of the Hologic Board of Directors until the
next annual meeting of the stockholders of Hologic and until his successor is
duly elected or appointed.  Hologic shall cause Employee to be nominated 

                                      A-80

<PAGE>
 
for election to its Board of Directors at the annual meeting of the stockholders
of Hologic following the Effective Date; provided, however, that if, at any time
                                         --------  -------                      
after the Effective Date but prior to such meeting, Employee ceases to serve as
an executive officer of either the Company or Hologic, then Hologic shall not be
obligated to cause Employee to be nominated for election to its Board of
Directors at such meeting; and, provided, further, if at any time after the
                                --------  -------
Effective Date but prior to the first anniversary of the Effective Date the
Employee ceases to serve as an executive officer of either the Company or
Hologic, if the Board of Directors of Hologic so requests, Employee shall
immediately tender his resignation from such Board and shall automatically be
deemed to have so resigned whether or not such resignation is tendered. If
Employee has satisfied the requirements set forth in the preceding sentence,
Hologic shall also cause Employee to be nominated for election to its Board of
Directors at the second annual meeting of the stockholders of Hologic following
the Effective Date; provided, however, that if, at any time after the Effective
                    --------  -------
Date but prior to the first anniversary of the such second meeting, Employee
ceases to serve as an executive officer of either the Company or Hologic, then
Hologic shall not be obligated to cause Employee to be nominated for election to
its Board of Directors at such meeting; and, provided, further, if at any time 
                                             --------  -------
after the Effective Date but prior to the second anniversary of the Effective
Date the Employee ceases to serve as an executive officer of either the Company
or Hologic, if the Board of Directors of Hologic so requests, Employee shall
immediately tender his resignation from such Board and shall automatically be
deemed to have so resigned whether or not such resignation is tendered. Except
as provided in this Section 1(c), Hologic shall have no obligation to cause
Employee to be elected or nominated for election to its Board of Directors.

    (d)  Hologic shall cause Employee to be indemnified as a director and
officer of Hologic and FluoroScan and to be advanced expenses to the same extent
that indemnification and advancement of expenses is provided by Hologic to its
remaining directors. An indemnification agreement to that effect will be entered
into between Hologic and the Employee at the Closing of the Merger.

    2    Term.  Employee's employment pursuant to the terms of this Agreement
         ----                                                                
shall commence upon the consummation of the Merger and the closing under the
Merger Agreement (the "Effective Date") and, subject to the rights of
termination provided for elsewhere herein, shall end on February 15, 1999 (the
"Term").  Upon the expiration of the Term, the employment relationship created
hereby shall continue on an at will basis, subject to the provisions of Sections
12, 13, 14, 16, 17, 19, 20, 23 and 27 of this Agreement.  Notwithstanding the
foregoing, if the Merger Agreement is terminated prior to the consummation of
the Merger, this Agreement shall be null and void and the Existing Employment
Agreement shall automatically continue as if this Agreement were never entered
into.

    3    Salary.  During the term of Employee's employment pursuant to this
         ------                                                            
Agreement in consideration for the services to be rendered by Employee to the
Company and to Hologic, the Company shall pay Employee an annual salary equal to
Two Hundred Twenty Thousand Dollars ($220,000), subject to adjustment as set
forth below and prorated for any partial year of employment (the "Base Salary").
Commencing on or about February 15, 1997 and on or about each February 15
thereafter during the Term of this Agreement, to the extent Employee is 

                                      A-81

<PAGE>
 
employed hereunder, the Board of Directors of the Company shall perform a review
of Employee's Base Salary and may, in its sole discretion, make such increases
(but no decreases) in such Base Salary as the Board determines to be
appropriate. Any such increase in the Base Salary shall be effective as of
February 15 of the year in which the Board of Directors of the Company
authorizes the increase. Notwithstanding anything to the contrary contained
herein, Employee's Base Salary shall be increased annually by not less than five
percent (5%) of the Base Salary for the prior year. The annual salary shall be
paid in equal installments in accordance with the Company's regular payroll
practices, but in no event less often than monthly.

     4    Discretionary Bonus.  The Board of Directors of the Company or of
          -------------------                                              
Hologic, in each case, in their sole discretion, may elect to award to Employee
a bonus (the "Discretionary Bonus") in an amount to be determined by such Board
in its sole judgment.  Notwithstanding the foregoing, Employee shall be entitled
to the bonus for 1996 that was previously approved by the Company's Board of
Directors and disclosed to Hologic (the "Approved Bonus").

     5    Expenses.  During the term of Employee's employment pursuant to this
          --------                                                            
Agreement, Employee shall be reimbursed for all reasonable and ordinary,
business expenses.  Employee shall furnish the Company and Hologic with the
appropriate documentation relating to such expenses and shall comply with any
additional requirements of the Company and Hologic generally applicable to the
Company's and Hologic's employees in connection therewith.  In addition,
Employee shall receive a car allowance of $420 per month.

     6    Fringe Benefits.  During the term of Employee's employment pursuant to
          ---------------                                                       
this Agreement, Employee shall be entitled to the fringe benefits no less
favorable than those generally made available to officers of Hologic from time
to time including but not limited to health care coverage (for himself and his
dependents, subject to co-payment obligations on the same basis as the executive
officers of Hologic) and long term disability coverage, as approved by the Board
of Directors of the Company or Hologic; provided, however, that the fringe
                                        --------  -------                 
benefits made available to Employee by the Company prior to the Merger shall be
deemed for purposes of this Section 6 to be as favorable as those made available
to officers of Hologic and Hologic may, in its sole discretion, elect to keep in
place any fringe benefit offered by the Company immediately prior to the Merger
or to replace any such benefit with a comparable fringe benefit; provided,
further, that if the Company elects to terminate its existing health care
coverage and to cover the Employee and his dependents under another health plan,
such plan will contain a waiver of preexisting medical conditions.  To the
extent that the availability or amount of any fringe benefit is based upon years
of service with Hologic, in determining the amount or types of benefits to which
Employee is entitled, Employee shall receive credit for his years of service as
a director or employee of the Company prior to the Merger, subject, however, to
the terms of the applicable benefit plan.

     7    Vacation.  During each year of the term of Employee's employment
          --------                                                        
pursuant to this Agreement, Employee shall be entitled to paid vacation in
accordance with Hologic's existing vacation practices, such vacations to be
taken at such times as not to disrupt the business of the Company.  For such
purpose, Employee shall receive credit for years of service to the 

                                      A-82

<PAGE>
 
Company prior to the date of the Merger. Notwithstanding the foregoing, Employee
shall be entitled to a paid vacation of not less than four weeks per calendar
year.

    8    Life Insurance.   During the term of the Company's employment pursuant
         --------------                                                        
to this Agreement, the Company shall continue to maintain two split dollar life
insurance policies on the life of Employee in the amount of One Million Dollars
($1,000,000) each; provided, however, that the maximum amount of aggregate
                   --------  -------                                      
premiums that the Company shall be obligated to pay for both of the Insurance
Policies shall not exceed Thirty Thousand Dollars ($30,000) per annum pro rated
for any partial year, and Employee understands and agrees that he shall be
personally responsible for premiums in excess of such amount; provided, however,
that if such premiums shall at any time exceed $30,000 per annum, Employee may
elect to decrease the amount of coverage under such policies such that the
premium will not exceed $30,000 per annum.  Employee's spouse shall be the
beneficiary of one such policy, and Employee's children shall be the beneficiary
of the other policy.  Employee may designate additional or different
beneficiaries for such Insurance Policies from time to time.  The Company will
maintain ownership of the policies including the cash value of the policies.
Upon termination of the Employee's employment pursuant to this Agreement, the
Employee shall have the option to purchase either or both of these policies from
the Company for the cash value thereof.

    9    Full-Time Duties.  Employee shall devote his full time, attention and
         ----------------                                                     
efforts to fulfill his duties hereunder and, to the business and interest of the
Company and Hologic, during the Term of this Agreement.  Notwithstanding the
foregoing, the Employee shall be permitted to serve on the Board of Director of
Trans Leasing International, Inc. and, subject to Section 13 and 14 hereof and
to the consent of Hologic (which consent will not be unreasonably withheld), on
the Board of Directors of other companies.

    10   Company and Hologic Policies and Procedures.  Employee agrees to comply
         -------------------------------------------                            
with the Company's and Hologic's regular employment policies and procedures as
they may be modified from time to time, provided that such policies and
procedures are communicated to Employee and apply to all employees, or all
executive employees, of the Company and Hologic on a uniform basis.  Employee
acknowledges having received copies the Company's and Hologic's employee
handbooks which contain some of the current polices and procedures of the
Company and Hologic.

    11   Early Termination.
         ----------------- 

    (a)  Termination by the Company and Hologic.  This Agreement shall
         --------------------------------------                       
automatically terminate upon the death of Employee.  At the election of the
Company and Hologic, Employee's employment pursuant to this Agreement shall
terminate prior to the expiration of the Term upon the earliest to occur of the
following: (i) the "long-term disability" of Employee; or (ii) the termination
of Employee by the Company for "just cause" pursuant to written notice thereof.

    For purposes hereof, "long term disability" shall be deemed to have occurred
if Employee is unable to perform, after reasonable accommodations by the
Company, by reason of physical or 

                                      A-83

<PAGE>
 
mental incapacity, the essential functions of his duties and obligations under
this Agreement, for a total period of 180 consecutive days in any 360-day
period. The Board of Directors of the Company (the "Board") shall determine,
according to the facts then available, whether and when "long term disability"
of the Employee has occurred. Such determination shall not be arbitrary or
unreasonable, and the Board shall take into consideration the opinion of
Employee's personal physician, if reasonably available, but such determination
by the Board shall be final and binding on the parties hereto.

    Notwithstanding the foregoing, if during the six month period commencing on
the date Employee is terminated due to "long term disability", the Board
determines that Employee no longer has a "long term disability" because Employee
is again able, and for the remainder of the Term will be able, to perform the
essential functions of his duties and obligations under this Agreement, the
Company will reinstate Employee's employment under the terms and conditions of
this Agreement.  The Board's determination as to whether Employee no longer has
a "long term disability" shall not be arbitrary or unreasonable, and the Board
shall take into consideration the opinion of Employee's personal physician, if
reasonably available, but such determination by the Board shall be final and
biding on the parties hereto.  In the event Employee is reinstated hereunder,
the Term will be deemed to recommence on the date of such reinstatement.

    For purposes hereof, "just cause" shall mean the occurrence of any of the
following events during the Term:

         (i)  a material breach of this Agreement by Employee which is not cured
         or remedied within ten (10) business days of written notice to the
         Employee, indicating the manner in which such breach can be cured or
         remedied, provided, however, that if such breach is not capable of
                   --------  -------                                       
         being cured or remedied within ten (10) business days, and if Employee
         takes all reasonable steps to initiate the cure of such breach within
         such 10-day period, proceeds at all times thereafter diligently and in
         good faith to complete the cure thereof, and completes the cure thereof
         within 20 business days of such notice, "just cause" shall not be
         deemed to exist; provided, further, that if such breach is a repeated
         material breach for which Employee has previously received notice, then
         the Company or Hologic may terminate the employment of Employee
         effective immediately;

         (ii)  criminal misconduct directly affecting the Company or Hologic;

         (iii)  unethical conduct  which reflects adversely upon Employee's
         honesty or integrity in the performance of his duties as an employee of
         the Company or Hologic and which otherwise is materially detrimental to
         the interests of the Company or Hologic;

         (iv)  if the Employee is found guilty or pleads nolo contendere to the
         commission of a crime classified as a felony under any Federal or state
         law;

         (v) chronic abuse of drugs or alcohol which continues after written
         notice to the

                                      A-84

<PAGE>
 
         Employee;
 

         (vi)  violation of any covenant contained in Section 13 or 14 hereof;
         and

         (vii)  the discovery by the Company or Hologic of a breach or breaches
         of  any of the representations, warranties or covenants of the Company
         contained in the Merger Agreement, which breach or breaches either
         individually or in the aggregate would have a Company Material Adverse
         Effect (as defined in the Merger Agreement) and which breach or
         breaches were known or should have been known to Employee prior to the
         closing of the Merger and were not disclosed to Hologic prior to said
         closing.


    Notwithstanding anything to the contrary set forth herein, at any time on or
after delivery of written notice to the Employee, the Company or Hologic may
relieve the Employee of all of his duties and responsibilities hereunder and may
relieve the Employee of authority to act on behalf of, or legally bind, the
Company and Hologic, provided, however, that any such action by the Company or
                     --------  -------                                        
Hologic, other than with "just cause" or as a result of the death or "long-term
disability" of Employee shall not relieve the Company of its obligation to pay
to the Employee all compensation and benefits provided for in this Agreement for
the balance of the Term.

    (b) Termination by Employee. At the election of Employee, Employee's
        -----------------------                                         
employment pursuant to this Agreement shall terminate prior to the expiration of
the Term upon the occurrence of an event constituting "good reason" (as defined
below), pursuant to written notice thereof to the Company and Hologic.

    For purposes hereof, "good reason" shall mean the occurrence of any of the
following events during the Term:

    (i)  a material breach of this Agreement by the Company or Hologic which is
not cured or remedied within ten (10) business days of written notice to the
Company and Hologic, indicating the manner in which such breach can be cured or
remedied; provided, however, that if such breach is not capable of being cured
          -----------------                                                   
or remedied within ten (10) business days, and if the Company takes all
reasonable steps to initiate the cure of such breach within such 10-day period,
proceeds at all time thereafter diligently and in good faith to complete the
cure thereof, and completes the cure thereof within 20 business days of such
notice, "good reason" shall not be deemed to exist.

    (ii)   any required relocation of the Employee outside of the Chicago,
Illinois metropolitan area;

    (iii)  any travel obligations which are materially in excess of those
required by the Company in the past;

                                      A-85

<PAGE>
 
    (iv) any assignment of duties inconsistent with those described in Section 1
hereof;

    (v)  any sale by Hologic to a third party of more than 51% of the stock or
assets of the Company to a party not controlled directly or indirectly by
Hologic; and

    (vi) any change in the consistency of the Board of Directors of Hologic
whereby more than 50% of the present directors are no longer serving as
directors, unless (and only so long as) S. David Ellenbogen is still serving as
Chief Executive Officer of Hologic.

The termination by the Employee's employment hereunder for good reason shall not
relieve the Company of its obligation to pay the Employee all compensation and
benefits as provided for in this Agreement for the balance of the Term.

    (c) Effect of Termination.  In the event of termination of the Employee's
        ---------------------                                                
employment by the Company for "just cause" or by the Employee other than for
"good reason," without limiting any other rights that the Company or Hologic may
have, Employee agrees that neither the Company or Hologic shall be required to
pay Employee any further compensation or benefits, to the extent permitted by
law, other than his Base Salary, Approved Bonus (but no other bonus) and car
allowance accrued to the effective date of termination and all reimbursable
expenses incurred prior to such date; provided, however, that if Employee
voluntarily terminates his employment hereunder without "good reason", he shall
not be entitled to any portion of his Accrued Bonus not previously paid to
Employee.

    12   Intellectual Property.
         --------------------- 

    (a)  Employee agrees to promptly disclose to the Company and Hologic all
ideas and suggestions coming within the scope of the business of the Company,
Hologic or any of Hologic's other subsidiaries, affiliates or successors,
whether now existing or hereafter arising and wherever located, which were
conceived or refined by him during his employment hereunder, or during his
previous affiliation with the Company, whether or not conceived or made during
regular working hours, and all such ideas and suggestions shall be the sole
property of the Company.  In the event that any such idea or suggestion is
deemed by the Company or Hologic to be an invention of patentable nature,
Employee, whether or not in the employ of the Company or Hologic, will assist
the Company and Hologic in obtaining, maintaining and enforcing patents for the
invention in the United States of America and in any and all foreign countries.
In addition, Employee will supply evidence, give testimony, sign and execute all
papers and do all other legal and proper things which the Company or Hologic
reasonably may deem necessary for obtaining, maintaining, and enforcing patents
for said invention and for vesting in the Company or Hologic full title thereto.
The foregoing obligations of Employee shall be further subject to Employee being
reimbursed for his reasonable out-of-pocket expenses in connection with services
rendered by him pursuant to the previous two (2) sentences.

    (b) Employee acknowledges that all works of authorship (including, without
limitation, works of authorship that contain software program code) relating to
the business of the Company and produced during Employee's employment hereunder,
or during his previous affiliation with 

                                      A-86

<PAGE>
 
the Company, whether they are or are not created on the Company's or Hologic's
premises or during regular working hours, are works made for hire and are the

Information or Customer Information (as such terms are defined in Section 14)
during the Noncompetition Period.  Employee acknowledges that his participation
in the conduct of any such Business alone or with any person other than the
Company or Hologic will materially impair the Business and prospects of the
Company and Hologic.

Noncompetition Period, Employee shall not knowingly attempt to or assist any
other person in attempting to do any of the following:  (i) hire any director,

    14   Protection of Proprietary Information.  Employee recognizes that the
         -------------------------------------                               
Company, Hologic and their Affiliates are engaged in a continuous program of
research and development relating to their respective business opportunities,
market forecasting, data processing, operating procedures, products, methods,
systems, techniques, machinery, tooling, designs, specifications, processes,
plans "know how" and trade secrets and that the Company, Hologic and their
Affiliates have developed information regarding costs, profits, markets,
products, customer lists, tooling, designs, plans for present and future
development and expansion into new markets and other proprietary information,
which is secret and confidential in nature and is not available to the public,
which gives the Company, Hologic and their Affiliates a special competence in
their respective and various fields of endeavor which are otherwise deemed to be
proprietary to the Company, Hologic and/or their Affiliates, all of which have
been acquired or developed at considerable expense to the Company, Hologic and
their Affiliates.  Employee acknowledges that a relationship of confidence and
trust has been developed between Employee, the Company and Hologic with respect
to information of a confidential or secret nature made known to Employee during
the term of Employee's employment by the Company and Hologic.  The information
referred to in the preceding two sentences is hereafter collectively referred to
as the "Company Information."  Employee further recognizes that the Company,
Hologic and their Affiliates have obtained and have access to certain
information concerning their respective customers which the Company, Hologic and
such Affiliates treat and desire to continue to treat on a confidential basis
("Customer Information") and that Employee, during the course of his employment
with the Company and Hologic has and will continue to have access to such
Customer Information.  Accordingly, Employee agrees that:

    (a)  Employee shall not disclose, either directly or indirectly, under any
circumstances (except as reasonably required in furtherance of the business of
the Company), at any time, any of the Company Information or Customer
Information to any person, firm, corporation, association or other entity for
any reason or purpose whatsoever; provided that the Employee shall not be deemed
to be in breach of such covenant if (i) the Employee makes such disclosure
pursuant to a subpoena or order of a court of competent jurisdiction, (ii) the
Employee shall have promptly given written notice to the Company and Hologic of
the request or demand for such disclosure, (iii) the Company and Hologic have
been afforded the right to participate at their own expense in objecting to or
limiting the nature and scope of such disclosure and (iv) the disclosure is
subject to all judicial protection available for like material, such as
protective orders and sealed records of proceedings.  Employee further agrees
not to use any of the Company information or Customer Information in any
business which is competitive with the Business of the Company, Hologic or any
Affiliate.

                                      A-88

<PAGE>
 
    (b)  Employee further agrees that at any time upon the request of the
Company or Hologic, Employee will deliver to the Company all documents and data
of any nature in his possession or control pertaining to any Company Information
and Customer Information.

    15   Other Agreements.  Employee represents and warrants to the Company and
         ----------------                                                      
Hologic, that as of the Effective Date Employee is not under any obligation to
any person or entity which is inconsistent with or in conflict with any of the
terms of this Agreement or which would prevent, limit or impair in any way
Employee's performance of all the terms of this Agreement and Employee agrees
not to enter into any agreement, either written or oral, in conflict herewith.

    16   Remedies.  The Employee expressly acknowledges that, in the event that
         --------                                                              
the provisions of Sections 12, 13 or 14 hereof are breached, the Company and
Hologic will suffer damages incapable of ascertainment and will be irreparably
damaged if any provision of such Sections is not enforced.  Therefore, should
any dispute arise with respect to the breach or threatened breach of any
provision of said Sections 12, 13 or 14, the Employee agrees and consents that,
in addition to any and all other remedies available to the Company and Hologic,
an injunction or restraining order or other equitable relief may be issued or
ordered by a court of competent jurisdiction restraining any breach of
threatened breach of any of such provisions.  The Employee consents that, for
purposes of any action initiated against the Employee hereunder, service of
process may be effected by certified mail or overnight receipted courier as set
forth in Section 20 hereof and shall be acceptable and adequate to satisfy the
requirement that service of process be served on the Employee in connection
therewith.  All such proceedings may be pursued and such remedies sought and
obtained concurrently or consecutively at the election of the Company.

    17   Integral Part of Transaction; Protection of Interests. Pursuant to the
         -----------------------------------------------------                 
Merger Agreement, Hologic is acquiring all of the business and goodwill of the
Company, and the undertakings and covenants of the Employee contained in this
Agreement are an integral part of the transactions set forth in said Merger
Agreement.  The Employee acknowledges, warrants and agrees that the restrictive
covenants contained in Sections 12, 13 and 14 of this Agreement are necessary
for the protection of the business investment by Hologic in the Merger and the
legitimate business interest of the Company, Hologic and their Affiliates,
respectively, and are reasonable in scope and content.  The Employee further
acknowledges and agrees that the territorial, time and other limitations imposed
hereunder upon the current and future business activities of the Employee are
reasonable and properly required for the adequate protection of the business
investment by Hologic in the Merger and the business affairs of the Company,
Hologic and their Affiliates, respectively, and in the event any such
territorial, time or other limitations are found to be unreasonable by a court
of competent jurisdiction, the Employee agrees and submits to the reduction of
such territorial, time or other limitations to such an area, period or otherwise
as the court may determine to be reasonable.  In the event that any limitation
contained in Sections 12, 13 or 14 of this Agreement is found to be unreasonable
or otherwise invalid in whole or in part in any jurisdiction, the Employee
agrees that such limitations shall be and remain valid in all other
jurisdictions.

    18   Joint and Several Obligations.  Hologic shall be jointly and severally
         -----------------------------                                         
liable for the performance of the obligations of the Company under this
Agreement.

    19   Severability.  The parties agree that each provision contained in this
         ------------                                                          
Agreement shall be treated as a separate and independent clause, and the
unenforceability of any one clause shall in no way impair the enforceability of
any of the other clauses herein.  Moreover, if one or more of the provisions
contained in this Agreement shall for any reason be held to be excessively broad
as to scope, activity or subject, such provisions shall be construed by the
appropriate judicial body by limiting and reducing it or them, so as to be
enforceable to the extent compatible with the applicable law.

    20   Notices.  Any notice or other communication in connection with this
         -------                                                            
Agreement shall be deemed to be delivered if in writing and if either (a)

         ------                                                            
Agreement in consideration for the services to be rendered by Employee to the
Company and to Hologic, the Company shall pay Employee an annual salary equal to
Two Hundred Twenty Thousand Dollars ($220,000), subject to adjustment as set

Commencing on or about February 15, 1997 and on or about each February 15
thereafter during the Term of this Agreement, to the extent Employee is employed
hereunder, the Board of Directors of the Company shall perform a review of
Employee's Base Salary and may, in its sole discretion, make such increases (but
no decreases) in such Base Salary as the Board determines to be appropriate.
Any such increase in the Base Salary shall be effective as of February 15 of the
year in which the Board of Directors of the Company authorizes the increase.
Notwithstanding anything to the contrary contained herein,

Employee's Base Salary shall be increased annually by not less than five 
percent (5%) of the Base Salary for the prior year.  The annual salary shall 
be paid in equal installments in accordance with the Company's regular payroll 
practices, but in no event less often than monthly.

     4    Discretionary Bonus.  The Board of Directors of the Company or of
          -------------------                                              
Hologic, in each case, in their sole discretion, may elect to award to Employee
a bonus (the "Discretionary Bonus") in an amount to be determined by such Board
in its sole judgment.  Notwithstanding the foregoing, Employee shall be entitled
to the bonus for 1996 that was previously approved by the Company's Board of
Directors and disclosed to Hologic (the "Approved Bonus").

     5    Expenses.  During the term of Employee's employment pursuant to this
          --------                                                            
Agreement, Employee shall be reimbursed for all reasonable and ordinary,
business expenses.  Employee shall furnish the Company and Hologic with the
appropriate documentation relating to such expenses and shall comply with any
additional requirements of the Company and Hologic generally applicable to the
Company's and Hologic's employees in connection therewith.  In addition,
Employee shall receive a car allowance of $420 per month.

      6  Fringe Benefits.  During the term of Employee's employment pursuant to
         ---------------                                                       
this Agreement, Employee shall be entitled to the fringe benefits no less
favorable than those generally made available to officers of Hologic from time
to time including but not limited to health care coverage (for himself and his
dependents, subject to co-payment obligations on the same basis as the executive
officers of Hologic) and long term disability coverage, as approved by the Board
of Directors of the Company or Hologic; provided, however, that the fringe
                                        --------  -------                 
benefits made available to Employee by the Company prior to the Merger shall be
deemed for purposes of this Section 6 to be as favorable as those made available
to officers of Hologic and Hologic may, in its sole discretion, elect to keep in
place any fringe benefit offered by the Company immediately prior to the Merger
or to replace any such benefit with a comparable fringe benefit; provided,
further, that if the Company elects to terminate its existing health care
coverage and to cover the Employee and his dependents under another health plan,
such plan will contain a waiver of preexisting medical conditions.  To the
extent that the availability or amount of any fringe benefit is based upon years
of service with Hologic, in determining the amount or types of benefits to which
Employee is entitled, Employee shall receive credit for his years of service as
a director or employee of the Company prior to the Merger, subject, however, to
the terms of the applicable benefit plan.

    7    Vacation.  During each year of the term of Employee's employment
         --------                                                        
pursuant to this Agreement, Employee shall be entitled to paid vacation in
accordance with Hologic's existing vacation practices, such vacations to be
taken at such times as not to disrupt the business of the Company.  For such
purpose, Employee shall receive credit for years of service to the Company prior
to the date of the Merger.  Notwithstanding the foregoing, Employee shall be
entitled to a paid vacation of not less than four weeks per calendar year.

    8    Life Insurance.   During the term of the Company's employment pursuant
         --------------                                                        
to this Agreement, the Company shall continue to maintain two split dollar life
insurance policies on

the life of Employee in the amount of One Million Dollars ($1,000,000) each; 
provided, however, that the maximum amount of aggregate premiums that the
- --------  ------- 
Company shall be obligated to pay for both of the Insurance Policies shall not 
exceed Thirty Thousand Dollars ($30,000) per annum pro rated for any partial 
year, and Employee understands and agrees that he shall be personally 
responsible for premiums in excess of such amount; provided, however, that if 
such premiums shall at any time exceed $30,000 per annum, Employee may
elect to decrease the amount of coverage under such policies such that the
premium will not exceed $30,000 per annum.  Employee's spouse shall be the
beneficiary of one such policy, and Employee's children shall be the beneficiary
of the other policy.  Employee may designate additional or different
beneficiaries for such Insurance Policies from time to time.  The Company will
maintain ownership of the policies including the cash value of the policies.
Upon termination of the Employee's employment pursuant to this Agreement, the
Employee shall have the option to purchase either or both of these policies from
the Company for the cash value thereof.

    9    Full-Time Duties.  Employee shall devote his full time, attention and
         ----------------                                                     
efforts to fulfill his duties hereunder and, to the business and interest of the
Company and Hologic, during the Term of this Agreement.  Notwithstanding the
foregoing, subject to Section 13 and 14 hereof and to the consent of the Company
(which consent will not be unreasonably withheld), the Employee shall be
permitted to serve on the Board of Directors of other companies.

    10   Company and Hologic Policies and Procedures.  Employee agrees to comply
         -------------------------------------------                            
with the Company's and Hologic's regular employment policies and procedures as
they may be modified from time to time, provided that such policies and
procedures are communicated to Employee and apply to all employees, or all
executive employees, of the Company and Hologic on a uniform basis.  Employee
acknowledges having received copies the Company's and Hologic's employee
handbooks which contain some of the current policies and procedures of the
Company and Hologic.

    11   Early Termination.
         ----------------- 

    (a)  Termination by the Company and Hologic.  This Agreement shall
         --------------------------------------                       
automatically terminate upon the death of Employee.  At the election of the
Company and Hologic, Employee's employment pursuant to this Agreement shall
terminate prior to the expiration of the Term upon the earliest to occur of the
following: (i) the "long-term disability" of Employee; or (ii) the termination
of Employee by the Company for "just cause" pursuant to written notice thereof.

    For purposes hereof, "long term disability" shall be deemed to have occurred
if Employee is unable to perform, after reasonable accommodations by the
Company, by reason of physical or mental incapacity, the essential functions of
his duties and obligations under this Agreement, for a total period of 180
consecutive days in any 360-day period.  The Board of Directors of the Company
(the "Board") shall determine, according to the facts then available, whether
and when "long term disability" of the Employee has occurred.  Such
determination 

- -------------------------------------------------------------------------------
ALI Employment Agreement                                               Page 5

<PAGE>
 
shall not be arbitrary or unreasonable, and the Board shall take into 
consideration the opinion of Employee's personal physician, if reasonably 
available, but such determination by the Board shall be final and binding on the
parties hereto.

    Notwithstanding the foregoing, if during the six month period commencing on
the date Employee is terminated due to "long term disability", the Board
determines that Employee no longer has a "long term disability" because Employee
is again able, and for the remainder of the Term will be able, to perform the
essential functions of his duties and obligations under this Agreement, the
Company will reinstate Employee's employment under the terms and conditions of
this Agreement.  The Board's determination as to whether Employee no longer has
a "long term disability" shall not be arbitrary or unreasonable, and the Board
shall take into consideration the opinion of Employee's personal physician, if
reasonably available, but such determination by the Board shall be final and
biding on the parties hereto.  In the event Employee is reinstated hereunder,
the Term will be deemed to recommence on the date of such reinstatement.

    For purposes hereof, "just cause" shall mean the occurrence of any of the
following events during the Term:

         (i)    a material breach of this Agreement by Employee which is not 
         cured or remedied within ten (10) business days of written notice to 
         the Employee, indicating the manner in which such breach can be cured 
         or remedied, provided, however, that if such breach is not capable of
                      --------  -------                                       
         being cured or remedied within ten (10) business days, and if Employee
         takes all reasonable steps to initiate the cure of such breach within
         such 10-day period, proceeds at all times thereafter diligently and in
         good faith to complete the cure thereof, and completes the cure thereof
         within 20 business days of such notice, "just cause" shall not be
         deemed to exist; provided, further, that if such breach is a repeated
         material breach for which Employee has previously received notice, then
         the Company or Hologic may terminate the employment of Employee
         effective immediately;

         (ii)   criminal misconduct directly affecting the Company or Hologic;

         (iii)  unethical conduct  which reflects adversely upon Employee's
         honesty or integrity in the performance of his duties as an employee of
         the Company or Hologic and which otherwise is materially detrimental to
         the interests of the Company or Hologic;

         (iv)   if the Employee is found guilty or pleads nolo contendere to the
         commission of a crime classified as a felony under any Federal or state
         law;

         (v)    chronic abuse of drugs or alcohol which continues after written
         notice to the Employee;

         (vi)   violation of any covenant contained in Section 13 or 14 hereof;
         and

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

<PAGE>
 
         (vii)  the discovery by the Company or Hologic of a breach or breaches
         of any of the representations, warranties or covenants of the Company
         contained in the Merger Agreement, which breach or breaches either
         individually or in the aggregate would have a Company Material Adverse
         Effect (as defined in the Merger Agreement) and which breach or
         breaches were known or should have been known to Employee prior to the
         closing of the Merger and were not disclosed to Hologic prior to said
         closing.

    Notwithstanding anything to the contrary set forth herein, at any time on or
after delivery of written notice to the Employee, the Company or Hologic may
relieve the Employee of all of his duties and responsibilities hereunder and may
relieve the Employee of authority to act on behalf of, or legally bind, the
Company and Hologic, provided, however, that any such action by the Company or
                     --------  -------                                        
Hologic, other than with "just cause" or as a result of the death or "long-term
disability" of Employee shall not relieve the Company of its obligation to pay
to the Employee all compensation and benefits provided for in this Agreement for
the balance of the Term.

    (b)  Termination by Employee. At the election of Employee, Employee's
         -----------------------                                         
employment pursuant to this Agreement shall terminate prior to the expiration of
the Term upon the occurrence of an event constituting "good reason" (as defined
below), pursuant to written notice thereof to the Company and Hologic.

    For purposes hereof, "good reason" shall mean the occurrence of any of the
following events during the Term:

    (i)    a material breach of this Agreement by the Company or Hologic which 
is not cured or remedied within ten (10) business days of written notice to the
Company and Hologic, indicating the manner in which such breach can be cured or
remedied; provided, however, that if such breach is not capable of being cured
          -----------------                                                   
or remedied within ten (10) business days, and if the Company takes all
reasonable steps to initiate the cure of such breach within such 10-day period,
proceeds at all time thereafter diligently and in good faith to complete the
cure thereof, and completes the cure thereof within 20 business days of such
notice, "good reason" shall not be deemed to exist.

    (ii)   any required relocation of the Employee outside of the Chicago,
Illinois metropolitan area;

    (iii)  any travel obligations which are materially in excess of those
required by the Company in the past;

    (iv)   any assignment of duties inconsistent with those described in Section
1 hereof;

    (v)    any sale by Hologic to a third party of more than 51% of the stock or
assets of the Company to a party not controlled directly or indirectly by
Hologic; and

                                     A-99

<PAGE>
 
    (vi)   any change in the consistency of the Board of Directors of Hologic
whereby more than 50% of the present directors are no longer serving as
directors, unless (and only so long as) S. David Ellenbogen is still serving as
Chief Executive Officer of Hologic.

The termination by the Employee's employment hereunder for good reason shall not
relieve the Company of its obligation to pay the Employee all compensation and
benefits as provided for in this Agreement for the balance of the Term.

    (c)  Effect of Termination.  In the event of termination of the Employee's
         ---------------------                                                
employment by the Company for "just cause" or by the Employee other than for
"good reason," without limiting any other rights that the Company or Hologic may
have, Employee agrees that neither the Company or Hologic shall be required to
pay Employee any further compensation or benefits, to the extent permitted by
law, other than his Base Salary, Approved Bonus (but no other bonus) and car
allowance accrued to the effective date of termination and all reimbursable
expenses incurred prior to such date; provided, however, that if Employee
voluntarily terminates his employment hereunder without "good reason", he shall
not be entitled to any portion of his Accrued Bonus not previously paid to
Employee.

    12   Intellectual Property.
         --------------------- 

    (a)  Employee agrees to promptly disclose to the Company and Hologic all
ideas and suggestions coming within the scope of the business of the Company,
Hologic or any of Hologic's other subsidiaries, affiliates or successors,
whether now existing or hereafter arising and wherever located, which were
conceived or refined by him during his employment hereunder, or during his
previous affiliation with the Company, whether or not conceived or made during
regular working hours, and all such ideas and suggestions shall be the sole
property of the Company.  In the event that any such idea or suggestion is
deemed by the Company or Hologic to be an invention of patentable nature,
Employee, whether or not in the employ of the Company or Hologic, will assist
the Company and Hologic in obtaining, maintaining and enforcing patents for the
invention in the United States of America and in any and all foreign countries.
In addition, Employee will supply evidence, give testimony, sign and execute all
papers and do all other legal and proper things which the Company or Hologic
reasonably may deem necessary for obtaining, maintaining, and enforcing patents
for said invention and for vesting in the Company or Hologic full title thereto.
The foregoing obligations of Employee shall be further subject to Employee being
reimbursed for his reasonable out-of-pocket expenses in connection with services
rendered by him pursuant to the previous two (2) sentences.

    (b)  Employee acknowledges that all works of authorship (including, without
limitation, works of authorship that contain software program code) relating to
the business of the Company and produced during Employee's employment hereunder,
or during his previous affiliation with the Company, whether they are or are not
created on the Company's or Hologic's premises or during regular working hours,
are works made for hire and are the property of the Company, and that copyrights
in those works of authorship are the property of

the Company.  If for any reason the Company or Hologic is not the author of 
any such work of authorship for copyright purposes, Employee hereby expressly 
assigns all of his rights in and to that work to the Company and agrees to 
sign any instrument of specific assignment requested.

    13   Noncompetition.
         -------------- 

    (a)  During the period commencing on the Effective Date and ending on the
later to occur of (i) February 15, 1999, or (ii) two (2) years following the
latest date on which Employee receives payments from the Company or Hologic
hereunder (whether in connection with Employee's employment hereunder or as a
result of the termination of Employee's employment hereunder) or otherwise in
connection with Employee's employment with the Company or Hologic after the
expiration of the Term (the "Noncompetition Period"), Employee shall not,
directly or indirectly, whether as owner, partner, shareholder, director,
consultant, agent, employee, guarantor, surety or otherwise, or through any
person, consult with or in any way aid or assist any competitor of the Company,
Hologic or any affiliate or successor entity thereof (each an "Affiliate") or
engage or attempt to engage in any employment, consulting or other activity
which directly or indirectly competes with the Business of the Company, Hologic
or any Affiliate.  For purposes of this Agreement, the term "employment" shall
include the performance of services by Employee as an employee, consultant,
agent, independent contractor or otherwise and the term "Business" shall mean
the research, development, manufacture, sale or distribution of any product (i)
within the X-ray bone densitometer, ultrasonic bone analyzer, biochemical marker
bone loss measurement, dual X-ray absorptiometry or low intensity, real time X-
ray imaging device industries, including without limitation medical and
commercial applications of such devices and technology and (ii) any other
business engaged in, planned or under development by the Company, Hologic or any
Affiliate with respect to which the Employee has had access to Company
Information or Customer Information (as such terms are defined in Section 14)
during the Noncompetition Period.  Employee acknowledges that his participation
in the conduct of any such Business alone or with any person other than the
Company or Hologic will materially impair the Business and prospects of the
Company and Hologic.

    (b)  In addition to and without limiting the foregoing, during the
Noncompetition Period, Employee shall not knowingly attempt to or assist any
other person in attempting to do any of the following:  (i) hire any director,
officer, employee, or agent of the Company, Hologic or any Affiliate or
encourage any such person to terminate such relationship with the Company,
Hologic or any Affiliate, as the case may be, (ii) encourage any customer,
client, supplier or other business relationship of the Company, Hologic or any
Affiliate to terminate or alter such relationship, whether contractual or
otherwise, to the disadvantage of the Company, Hologic or any Affiliate, as the
case may be (iii) encourage any prospective customer or supplier not to enter
into a business relationship with the Company, Hologic or any Affiliate; (iv)
impair or attempt to impair any relationship, contractual or otherwise, written
or oral, between the Company, Hologic or any Affiliate and any customer,
supplier or other business relationship of the Company, Hologic or any Affiliate
or; (v) sell or offer to sell or assist in or in connection with the sale to any

    (c)  Nothing in this Agreement shall preclude Employee from making passive
investments of not more than 2% of a class of securities of any business
enterprise registered under the Securities Exchange Act of 1934.

    14   Protection of Proprietary Information.  Employee recognizes that the
         -------------------------------------                               
Company, Hologic and their Affiliates are engaged in a continuous program of
research and development relating to their respective business opportunities,
market forecasting, data processing, operating procedures, products, methods,
systems, techniques, machinery, tooling, designs, specifications, processes,
plans "know how" and trade secrets and that the Company, Hologic and their
Affiliates have developed information regarding costs, profits, markets,
products, customer lists, tooling, designs, plans for present and future
development and expansion into new markets and other proprietary information,
which is secret and confidential in nature and is not available to the public,
which gives the Company, Hologic and their Affiliates a special competence in
their respective and various fields of endeavor which are otherwise deemed to be
proprietary to the Company, Hologic and/or their Affiliates, all of which have
been acquired or developed at considerable expense to the Company, Hologic and
their Affiliates.  Employee acknowledges that a relationship of confidence and
trust has been developed between Employee, the Company and Hologic with respect
to information of a confidential or secret nature made known to Employee during
the term of Employee's employment by the Company and Hologic.  The information
referred to in the preceding two sentences is hereafter collectively referred to
as the "Company Information."  Employee further recognizes that the Company,
Hologic and their Affiliates have obtained and have access to certain
information concerning their respective customers which the Company, Hologic and
such Affiliates treat and desire to continue to treat on a confidential basis
("Customer Information") and that Employee, during the course of his employment
with the Company and Hologic has and will continue to have access to such
Customer Information.  Accordingly, Employee agrees that:

    (a)  Employee shall not disclose, either directly or indirectly, under any
circumstances (except as reasonably required in furtherance of the business of
the Company), at any time, any of the Company Information or Customer
Information to any person, firm, corporation, association or other entity for
any reason or purpose whatsoever; provided that the Employee shall not be deemed
to be in breach of such covenant if (i) the Employee makes such disclosure
pursuant to a subpoena or order of a court of competent jurisdiction, (ii) the
Employee shall have promptly given written notice to the Company and Hologic of
the request or demand for such disclosure, (iii) the Company and Hologic have
been afforded the right to participate at their own expense in objecting to or
limiting the nature and scope of such disclosure and (iv) the disclosure is
subject to all judicial protection available for like material, such as
protective orders and sealed records of proceedings.  Employee further agrees
not to use any of the Company information or Customer Information in any
business which is competitive with the Business of the Company, Hologic or any
Affiliate.

    (b)  Employee further agrees that at any time upon the request of the
Company or Hologic, Employee will deliver to the Company all documents and data
of any nature in his possession or control pertaining to any Company Information
and Customer Information.

    15   Other Agreements.  Employee represents and warrants to the Company and
         ----------------                                                      
Hologic, that as of the Effective Date Employee is not under any obligation to
any person or entity which is inconsistent with or in conflict with any of the
terms of this Agreement or which would prevent, limit or impair in any way
Employee's performance of all the terms of this Agreement and Employee agrees
not to enter into any agreement, either written or oral, in conflict herewith.

    16   Remedies.  The Employee expressly acknowledges that, in the event that
         --------                                                              
the provisions of Sections 12, 13 or 14 hereof are breached, the Company and
Hologic will suffer damages incapable of ascertainment and will be irreparably
damaged if any provision of such Sections is not enforced.  Therefore, should
any dispute arise with respect to the breach or threatened breach of any
provision of said Sections 12, 13 or 14, the Employee agrees and consents that,
in addition to any and all other remedies available to the Company and Hologic,
an injunction or restraining order or other equitable relief may be issued or
ordered by a court of competent jurisdiction restraining any breach of
threatened breach of any of such provisions.  The Employee consents that, for
purposes of any action initiated against the Employee hereunder, service of
process may be effected by certified mail or overnight receipted courier as set
forth in Section 20 hereof and shall be acceptable and adequate to satisfy the
requirement that service of process be served on the Employee in connection
therewith.  All such proceedings may be pursued and such remedies sought and
obtained concurrently or consecutively at the election of the Company.

    17   Integral Part of Transaction; Protection of Interests. Pursuant to the
         -----------------------------------------------------                 
Merger Agreement, Hologic is acquiring all of the business and goodwill of the
Company, and the undertakings and covenants of the Employee contained in this
Agreement are an integral part of the transactions set forth in said Merger
Agreement.  The Employee acknowledges, warrants and agrees that the restrictive
covenants contained in Sections 12, 13 and 14 of this Agreement are necessary
for the protection of the business investment by Hologic in the Merger and the
legitimate business interest of the Company, Hologic and their Affiliates,
respectively, and are reasonable in scope and content.  The Employee further
acknowledges and agrees that the territorial, time and other limitations imposed
hereunder upon the current and future business activities of the Employee are
reasonable and properly required for the adequate protection of the business
investment by Hologic in the Merger and the business affairs of the Company,
Hologic and their Affiliates, respectively, and in the event any such
territorial, time or other limitations are found to be unreasonable by a court
of competent jurisdiction, the Employee agrees and submits to the reduction of
such territorial, time or other limitations to such an area, period or otherwise
as the court may determine to be reasonable.  In the event that any limitation
contained in Sections 13 or 14 of this Agreement is found to be unreasonable or
otherwise invalid in whole or in part in any jurisdiction, the Employee agrees
that such limitations shall be and remain valid in all other jurisdictions.

    18   Joint and Several Obligations.  Hologic shall be jointly and severally
         -----------------------------                                         
liable for the performance of the obligations of the Company under this
Agreement.

Dear Sirs:

undersigned upon exercise of any employee stock options or warrants, until after
such time as the Parent has published (within the meaning of Accounting Series
Release No. 130, as amended, of the Securities and Exchange Commission)

Company and the Parent.

          (b)  Until the earlier of the Effective Time (as defined in the

                          Opinion of Company's Counsel
                          ----------------------------

     The following opinions and confirmations will be subject to customary
assumptions and qualifications, including, but not limited to, compliance with
all applicable fiduciary duties.

1.   Each of the Company and its Subsidiaries is a corporation duly
     incorporated, existing and in good standing under the laws of the
     jurisdiction of its incorporation, with the corporate power and authority
     to own or lease its properties and to conduct its business as presently
     conducted.

2.   The Company is qualified to do business and is in good standing as a
     foreign corporation in the States of Illinois and Michigan.

3.   The Company has the corporate power and authority to enter into the
     Agreement and to perform its obligations thereunder. The execution and
     delivery by the Company of each of the Agreement and the Employment
     Agreements have been duly authorized by all necessary corporate action,
     including with regard to the Agreement, stockholder action, on the part of
     the Company, has been duly executed and delivered by the Company, and
     constitutes the legal, valid and binding obligation of the Company,
     enforceable against the Company in accordance with its terms.

4.   The authorized capital stock of the Company consists of (i) 1,000,000
     shares of preferred stock, $.0001 par value, none of which are issued and
     outstanding, and (ii) 14,000,000 shares of common stock, $.0001 par value,
     of which ____ shares were issued and outstanding at the close of business
     on ________________[one business day prior to the date hereof] and no
     shares are held in treasury of the Company. All such outstanding shares
     have been duly authorized and validly issued, and are fully paid and
     nonassessable.

5.   Except as disclosed in the Merger Agreement or the Company Disclosure
     Letter, the execution and delivery of the Agreement and consummation of the
     Merger and the other transactions contemplated thereby will not result in
     (i) a breach or violation of any of the terms or provisions of or
     constitute a default under or violate or conflict with the Charter or
     Bylaws of the Company or any of its Subsidiaries, (ii) to our knowledge, a
     breach or violation of any provision of any material contract or agreement
     (a) listed in the Company Disclosure Schedule or as an exhibit or
     incorporated by reference as an exhibit to the Company's 1995 Annual Report
     on Form 10-K or any subsequent Company SEC filings, to which the Company or
     any of its Subsidiaries is a party or by which the Company or any of its
     Subsidiaries is bound (the "Material Contracts"), or give rise to a right
     of termination of any such Material Contract or (iii) the creation of any
     lien on any property of the Company, any of its Subsidiaries or the
     Surviving Corporation (except due to acts of Parent or the Acquisition
     Subsidiary). To our knowledge, the Company is not a party to, or expressly
     bound by, any judgment, injunction or decree of any court or governmental
     authority which would restrict or interfere with the performance by the
     Company of its obligations under the

                                     A-109

<PAGE>
 
     Agreement. We express no opinion as to any agreement between the Company
     and NASA, which is the subject of a opinion of special government contract
     counsel.

6.   To our knowledge, all authorizations, consents and approvals of all federal
     and state governmental agencies required in order to permit the
     consummation of the Merger and the other transactions contemplated by the
     Agreement on the part of the Company and each of its Subsidiaries have been
     obtained, except for (i) the filing of the Certificate of Merger with the
     Delaware Secretary of State, and (ii) approvals and registrations which if
     not obtained would not have a Company Material Adverse Effect. We express
     no opinion as to any agreement between the Company and NASA, which may be
     the subject of a opinion of special government contract counsel.

7.   Each of the Employment Agreement, Stock Option Agreement, and Voting Rights
     Agreement entered into in connection with the Agreement (collectively the
     "Ancillary Agreements") has been duly executed and delivered by Larry S.
     Grossman and/or Arlen L. Issette (each a "Company Affiliate"), constitutes
     the legal, valid and binding obligation of the applicable Company
     Affiliate, enforceable against such Company Affiliate in accordance with
     its terms.

8.   The performance of the Ancillary Agreements and the consummation of the
     transactions therein provided will not, to our knowledge, result in a
     breach or violation of any provision of any material contract or instrument
     to which any Company Affiliate is bound. To our knowledge, no Company
     Affiliate is a party to, or expressly bound by, any judgment, injunction or
     decree of any court of government authority which would restrict or
     interfere with the performance by any Company Affiliate of its obligations
     under the Ancillary Agreements to which it is a party.

9.   Upon the filing of the Certificate of Merger with the Secretary of State of
     the State of Delaware, the Merger will be effective under Delaware law.

10.  To our knowledge, the NASA License Agreement is a valid and binding
     agreement of the Company and, assuming the due authorization and execution
     thereof by NASA and that the NASA License Agreement is in full force and
     effect, is enforceable by the Company in accordance with its terms, and the
     consummation of the Merger will not result in a breach or violation of the
     Agreement or the right of NASA to terminate the agreement. [This opinion
     may be rendered by special government contract counsel.]

11.  To our knowledge, the Company has filed with the Commission all forms,
     statements, reports and documents (including all exhibits, amendments, and
     supplements thereto) required to be filed by it under each of the
     Securities Act and the Exchange Act since July 11, 1994, and the respective
     rules and regulations thereunder, all of which complied as to form in all
     material respects with all applicable requirements of the appropriate Act
     and the rules and regulations thereunder, it being understood that we do
     not express any opinion with respect to the operating statistics, financial
     statements, financial schedules and other financial and statistical data
     included therein.

                                      A-110

<PAGE>
 
12.  The Proxy Statement/Prospectus complied as to form in all material respects
     with the requirements of the Securities Act and the Exchange Act and with
     the rules and regulations of the Commission thereunder, it being understood
     that we do not express any opinion with respect to the operating
     statistics, financial statements, financial schedules and other financial
     and statistical data included therein, or any information relating to or
     furnished by the Parent or the Acquisition Subsidiary.

The following numbered paragraphs may be in the form of a confirmation in the
Opinion Letter and not a numbered opinion:

1.   We have participated in conferences with Larry S. Grossman and Arlen L.
     Issette, the Chairman of the Board and President of the Company and other
     representatives of the Company, representatives of the Parent,
     representatives of Brown, Rudnick, Freed & Gesmer, legal counsel for the
     Parent, representatives of BDO Seidman, LLP, the independent public
     accountants for the Company, and representatives of Arthur Andersen LLP,
     the independent public accountants for the Parent, at which conferences we
     made inquiries of such representatives of the Company and the
     representatives of the Company's independent public accountants, and
     discussed the contents of the Registration Statement, the Proxy
     Statement/Prospectus and related matters and, although we are not passing
     upon and do not assume any responsibility for the accuracy, completeness or
     fairness of the statements contained in any Registration Statement or the
     Proxy Statement/Prospectus, on the basis of the foregoing, and solely with
     respect to the Company and its Subsidiaries, no facts have come our
     attention which give us reason to believe that the Registration Statement,
     as of its effective date under the Securities Act, as of the meeting date
     of the shareholders of the Company (the "Meeting Date"), and as of the date
     hereof, contained or contains any untrue statement of a material fact or
     omitted or omits to state any material fact required to be stated therein
     or necessary to make the statements therein not misleading, or that the
     Proxy Statement/Prospectus, as of its mailing date to the shareholders of
     the Company, the Meeting Date and the date hereof, included or includes any
     untrue statement of a material fact or omitted or omits to state a material
     fact necessary in order to make the statements therein, in light of the
     circumstances under which they were made, not misleading, it being
     understood that we do not express any opinion with respect to the operating
     statistics, financial statements, financial schedules and other financial
     and statistical data included therein, or any information concerning or
     furnished by the Parent or the Acquisition Subsidiary.


2.   To our knowledge, based solely on an officer's certificate, except as set
     forth in the Agreement or the Company Disclosure Schedule and as
     contemplated by the Agreement, there are no (i) outstanding or authorized
     subscriptions, warrants, options or other rights granted by the Company or
     binding upon the Company to purchase or acquire, or preemptive rights with
     respect to the issuance or sale of, the capital stock of the Company or
     which obligate or may obligate the Company to issue any additional shares
     of its capital stock or any securities convertible into or evidencing the
     right to subscribe for any shares of its capital stock, (ii) other
     securities of the Company directly or indirectly convertible into or
     exchangeable for shares of capital stock of the Company, (iii) restrictions
     on the transfer of 

                                     A-111

<PAGE>
 
     the Company's capital stock, (iv) voting rights with respect to the capital
     stock of the Company, or (v) stock appreciation, phantom stock or similar
     rights with respect to the Company. To our knowledge, except as set forth
     in the Agreement or the Company Disclosure Schedule, no holders of
     securities of the Company have rights to register such securities for sale.

3.   To our knowledge, based solely on a review of our firm's litigation docket
     and an officer's certificate, except as disclosed in the Company Disclosure
     Schedule, there are no claims, actions, suits, arbitrations, proceedings or
     investigations pending (or, to our knowledge, overtly threatened in
     writing) against the Company or any of its Subsidiary, and there are no
     outstanding court orders, court decrees, or court stipulations to which the
     Company or any of its Subsidiary is a party or by which any of their
     respective assets are bound, any of which (a) if adversely determined would
     materially restrict or interfere with the Agreement or the transactions
     contemplated thereby, or (b) materially restrict the present business
     properties, operations, prospects, assets, revenues or condition (financial
     or otherwise) of the Company or any of its Subsidiaries, or (c) would,
     individually or in the aggregate, have a Company Material Adverse Effect or
     materially impair or preclude the Company's ability to consummate the
     Merger or the other transactions contemplated thereby.

                                                                       ---------


 
                                 July 18, 1996

                                FORM OF OPINION
                            RE INTELLECTUAL PROPERTY

     Acting as special counsel, we have reviewed specified aspects of the
intellectual property rights ("the Intellectual Property") of Fluoroscan
Imaging Systems, Inc. ("Fluoroscan").

     In our review, we have relied upon the accuracy of factual information
provided by or for Fluoroscan. We have assumed the genuineness of all
signatures, the authenticity of all documents submitted to us, the conformity to
the originals of all documents submitted to us as copies, and the authority of
the originals of the copied documents. As to questions of fact material to our
opinion, we have relied on public records when available and representations of
representatives of Fluoroscan, when relevant facts were not or could not be
independently established.

     It is our opinion based upon the foregoing that the Intellectual Property
consists of:

     1.   License rights under U.S. Patents Nos. 4,142,101 ("'101 patent") and
          its Reexamination Certificate B1, 4,510,476 ("'476 patent") and
          4,517,472 ("'472 patent"), together with a license to use and sell
          under any foreign counterparts of these patents, products which
          Fluoroscan has manufactured in the United States;

     2.   The likely right to continue to use the name FLUOROSCAN in connection
          with Fluoroscan's current line of products; and

     3.   Such trade secrets as Fluoroscan has developed in its business and has
          maintained as such.

     We are not aware of any other intellectual property rights which Fluoroscan
owns, and our search in public databases has not revealed any such other rights.

A.   PATENT RIGHTS

     1.   Licensed Patents

     As of today, any required maintenance fees for the '101, '476 and '472
patents have been paid, and the patents are subsisting.

     The '101, '476 and '472 patents are assigned on their face to the United
States of America as represented by the Administrator for the National
Aeronautics and Space Administration ("NASA"). The records in the U-S-Patent and
Trademark Office, show that as of today these three patents are still assigned
to NASA. We have not uncovered information that would indicate otherwise.

     In our opinion, the three U.S. patents under which Fluoroscan is licensed
expire on the following dams::

                    '101 patent -- July 20, 1997
                    '476 patent -- June 21, 2003
                    '472 patent -- July 06, 2003
     In summary:

     1.   The '101 patent, as reexamined, pertains to and claims as the
          protected invention, a special image intensifier/screen combination,
          either alone or as a part of an x-ray system;

     2.   The '476 patent pertains to and claims as the protected invention, an
          electrical transformer that can be used in a power supply for an x-ray
          tube to step up relatively low voltage to relatively high voltage
          (such as to the voltage level needed to power an x-ray robe); and

     3.   The '472 patent pertains to and claims as the protected invention, a
          high voltage power supply circuit which can power an x-ray robe.

     In our opinion, the current Fluoroscan products use the inventions recited
in these three U.S. patents.

                                     A-114

<PAGE>
 
     We base our opinion regarding the licensed patents expressed above on our
study of the patents and their file histories, including prior an of record, on
our inspection of records maintained by the United States Patent and Trademark
Office, and on our inspection of the current Fluoroscan products and on
additional information supplied by Fluoroscan and its counsel.

2.   Patent Scope

     The '101 patent in our opinion covers an image intensifier/screen
combination having specified characteristics, and x-ray system using such a
combination, but may not cover certain other types of image intensifiers that
can be used in conjunction with screens in x-ray systems.

     The '476 and '472 patents in our opinion cover transformers and power
supply, respectively, such as used in Fluoroscan's current products, but may not
cover certain other transformers and power supplies that can be used in similar
products.

     We base our opinion regarding patent scope on our study of the patents, of
their file histories, of prior art of record therein, of additional prior art
uncovered in an independent search which we carried out, of the material
retained by Fluoroscan's counsel from the litigation involving the '101 patents,
and on our inspection of Fluoroscan's products and additional information
supplied by Fluoroscan and its counsel.

3.   Patent Validity

     In our opinion, the '101, '476 and '472 patents are valid.

     We base our opinion on validity on our study of the patents, of their file
histories, of prior art of record therein, of additional prior art uncovered in
an independent search which we carried out, of the material retained by
Fluoroscan's counsel from the litigation involving the '101 patents, and on
additional information supplied by Fluoroscan and its counsel.

4    Patent Enforceability

     In our opinion, the '101, '476 and '472 patents are enforceable.

                                     A-115

<PAGE>
 
     We base our opinion on enforceability on our study of the patents, of their
file histories, of prior art of record therein, of additional prior art
uncovered in an independent search which we carried out, of the material
retained by Fluoroscan's counsel from the litigation involving the '101 patents,
and on additional information supplied by Fluoroscan and its counsel.

5.   Subsisting License

     In our opinion, the license rights granted to Fluoroscan under the '101,
'476 and '472 patents subsist.

The license rights under the '101 patent are for a specified technology
("nonradioactive isotope" uses) and specified claims of the patent. The license
rights under the '476 and '472 patents are subject to a prior license granted in
the field of "Lixiscope" uses. Further, the license fights under all three
patents require manufacture in the U.S. There is no exclusivity in other
countries.  The licensor can terminate for cause, and Fluoroscan can terminate
at will upon notice.

     The license fights give Fluoroscan a qualified exclusivity in that:  (a)
the licensor can practice the patents at will and can make, use and sell such
products in competition with Fluoroscan; (b) the licensor can license others
under these patents if it determines that this would be required by factors such
as public health and the national interest; (c) Fluoroscan has sublicensed its
rights under the '101 patent (and the Reexamination Certificate for that patent)
to Xi Tec, Inc. ("Xi Tec") for the life of the '101 patent, pursuant to the
settlement of a lawsuit involving the '101 patent; and (d) the license to
Fluoroscan under the '476 and '472 patents is subject to a prior field-of-use
license to Hopkins International Company ("Hopkins").

     The license rights under each respective patent expire when the patent
expires, unless earlier terminated (e.g., for breach).

6.   Fluoroscan's Royalty Obligations

     In our opinion, the license rights under the three U.S. patents obligate
Fluoroscan to pay royalty. The royalty is at the rate of 4.5% while Fluoroscan's
products use all three patents. After the '101 patent expires (or if
Fluoroscan's 

                                     A-116

<PAGE>
 
products no longer use it, the royalty is at the rate of 3.5 % for the use of
either or both of the '476 and '472 patents.

     We base this opinion on our study of the license documents supplied to us
by Fluoroscan's counsel.

7.   Royalty Due To Fluoroscan

     In our opinion, Xi Tec, Inc. ("Xi Tee") has a sublicense under the '101
patent which obligates it to pay Fluoroscan a royalty of $1350 (and possibly an
additional $300) for each Xi Tec machine using the '101 patent, using the '101
patent expires in approximately one year. (In turn, Fluoroscan is obligated to
pay its licensor $300 of the royalty received per Xi Tec machine.)

     We base this information on our study of the license and sublicense
documents and information supplied to us by Fluoroscan and its counsel, and of
the material respecting the litigation involving the '101 patent retained by
Fluoroscan's counsel.

B.   RIGHTS IN THE NAME, FLUOROSCAN

     In our opinion, Fluoroscan likely has the right to continue using the name
Fluoroscan in connection with its current line of products, because it has used
it without challenge for an extended time period and for other reasons. However,
Fluoroscan has not been able to obtain a registration for that name because of a
prior use or registration of the same name by another.

     We base this opinion on documents and information supplied to us by
Fluoroscan and its counsel and our search of public records.

C.   TRADE SECRETS

     In our opinion, Fluoroscan owns certain trade secrets related to its
products and business, and has maintained them as such.

     We base this opinion on documents and information supplied to us by
Fluoroscan employees and counsel.

                                     A-117

<PAGE>
 
D.   EXPOSURE TO INTELLECTUAL PROPERTY OF OTHERS

     In our opinion, Fluoroscan's current and past products do not infringe
intellectual property of others which we have been able to uncover in our search
of public records.

     We base this opinion on our study of Fluoroscan's current and past
products, on the results of our search in public records, and on information
supplied to us by Fluoroscan and its counsel, including representations thereof
that Fluoroscan is unaware of any allegations that its products have infringed
intellectual property of others.

                                                                       ---------

                          Opinion of Parent's Counsel
                          ---------------------------

     The following opinions and confirmations will be subject to customary
assumptions and qualifications.

1.   Each of the Parent and the Acquisition Subsidiary is a corporation duly
     incorporated, existing and in good standing under the laws of the State of
     Delaware. The Parent has the corporate power and authority to own or lease
     its properties and to conduct is business as presently conducted.

2.   Each of the Parent and the Acquisition Subsidiary has the corporate power
     and authority to enter into the Agreement and to perform its respective
     obligations thereunder. The execution and delivery by the Parent of the
     Agreement has been duly authorized by all necessary corporate action on the
     part of the Parent, has been duly executed and delivered by the Parent, and
     constitutes the legal, valid and binding obligation of the Parent,
     enforceable against the Parent in accordance with its terms. The execution
     and delivery by the Acquisition Subsidiary of the Agreement has been duly
     authorized by all necessary corporate action on the part of the Acquisition
     Subsidiary, has been duly executed and delivered by the Acquisition
     Subsidiary, and constitutes the legal, valid and binding obligation of the
     Acquisition Subsidiary, enforceable against the Acquisition Subsidiary in
     accordance with its terms.

3.   The authorized capital stock of the Parent consists of (i) 1,622,685 shares
     of preferred stock, $.01 par value, none of which are outstanding, and (ii)
     30,000,000 shares of common stock, $.01 par value, of which ____ shares
     were issued and outstanding at the close of business on _______ [one
     business day prior to the date hereof]. Each share of Parent Common Stock
     is, and each share of Parent Common Stock to be issued to the stockholders
     of the Company at the Effective Time will be accompanied by one Parent
     Purchase Right. All of the issued and outstanding shares of Parent Common
     Stock are duly authorized, validly issued, fully paid and nonassessable.
     All of the Merger Shares will be, when issued in accordance with the
     Agreement, duly authorized, validly issued, fully paid and nonassessable.

4.   Except as disclosed in the Merger Agreement, the execution and delivery of
     the Agreement and consummation of the Merger and the other transactions
     contemplated thereby will not result in (i) a breach or violation of any of
     the terms or provisions of or constitute a default under or violate or
     conflict with the Charter or Bylaws of the Parent or the Acquisition
     Subsidiary, (ii) to our knowledge, a breach or violation of any provision
     of any material contract or agreement attached as or incorporated by
     reference as an exhibit to the Company's 1995 Annual Report on Form 10-K or
     any subsequent Company SEC filings to which the Parent or the Acquisition
     Subsidiary is a party or by which the Parent or the Acquisition Subsidiary
     is bound (the "Material Contracts"), or give rise to the right of
     termination of any such Material Contract or (iii) the creation of any lien
     on any property of the Parent or Acquisition

                                     A-119

<PAGE>
 
     Subsidiary (except due to acts of Parent or the Acquisition Subsidiary). To
     our knowledge, neither the Parent or the Acquisition Subsidiary is a party
     to, or expressly bound by, any judgment, injunction or decree of any court
     of governmental authority which would restrict or interfere with the
     performance by the Company of its obligations under the Agreement.

5.   To our knowledge, all authorizations, consents and approvals of all federal
     and state governmental agencies required in order to permit the
     consummation of the Merger and the other transactions contemplated by the
     Agreement on the part of the Parent and the Acquisition Subsidiary have
     been obtained, except for (i) the filing of the Certificate of Merger with
     the Delaware Secretary of State, and (ii) the approvals and registrations
     which if not obtained would not have a Parent Material Adverse Effect.

6.   Upon the filing of the Certificate of Merger with the Secretary of State of
     the State of Delaware, the Merger will be effective under Delaware law.

7.   To our knowledge, Parent has filed with the Commission all forms,
     statements, reports and documents (including all exhibits, amendments, and
     supplements thereto) required to be filed by it under each of the
     Securities Act and the Exchange Act since January 1, 1994, and the
     respective rules and regulations thereunder, all of which complied as to
     form in all material respects with all applicable requirements of the
     appropriate Act and the rules and regulations thereunder, it being
     understood that we do not need to express any opinion with respect to the
     operating statistics, financial statements, financial schedules and other
     financial and statistical data included therein.

8.   The Registration Statement has become effective under the Securities Act
     and to the best of our knowledge no stop order suspending the effectiveness
     of the Registration Statement has been issued and no proceedings for that
     purpose are pending or threatened by the Commission.

9.   The Registration Statement and the Proxy Statement/Prospectus included
     therein comply as to form in all material respects with the requirements of
     the Securities Act and the Exchange Act and with the rules and regulations
     of the Commission thereunder, it being understood that we do not need to
     express any opinion with respect to the operating statistics, financial
     statements, financial schedules and other financial and statistical data
     included therein or any information relating to or furnished by the Company
     or any of its Subsidiaries.

The following numbered paragraphs may be in the form of a confirmation in the
Opinion Letter and not a numbered opinion:

1.   We have participated in conferences with S. David Ellenbogen and Glenn P.
     Muir, the Chairman and Chief Financial Officer of the Parent, respectively,
     and other representatives of the Parent, representatives of the Company,
     representatives of Katten, Muchin & Zavis, counsel to the Company,
     representatives of BDO Seidman, LLP, the independent public accountants for
     the Company, and representatives of Arthur Andersen LLP, the independent
     public accountants for the Parent, at which conferences we made inquiries
     of such representatives of the Parent and the representatives of the
     Parent's independent public

                                     A-120

<PAGE>
 
     accountants, and discussed the contents of the Registration Statement, the
     Proxy Statement/Prospectus and related matters and, although we are not
     passing upon and do not assume any responsibility for the accuracy,
     completeness or fairness of the statements contained in any Registration
     Statement or the Proxy Statement/Prospectus, on the basis of the foregoing,
     and solely with respect to the Parent and the Acquisition Subsidiary, no
     facts have come to our attention which give us reason to believe that the
     Registration Statement, as of its effective date under the Securities Act,
     as of the meeting date of the shareholders of the Company in connection
     with the Transaction (the "Meeting Date") and as of the date hereof
     contained or contains any untrue statement of a material fact or omitted or
     omits to state any material fact required to be stated therein or necessary
     to make the statements therein not misleading, or that the Proxy
     Statement/Prospectus, as of its mailing date to the shareholders of the
     Company, the Meeting Date and the date hereof, included or includes any
     untrue statement of a material fact or omitted or omits to state a material
     fact necessary in order to make the statements therein, in light of the
     circumstances under which they were made, not misleading, it being
     understood that we do not need to express any opinion with respect to the
     operating statistics, financial statements, financial schedules and other
     financial and statistical data included therein, or any information
     concerning or furnished by the Company.

2.   To our knowledge, based solely on a review of our firm's case intake and an
     officer's certificate, except as disclosed in the Agreement, there are no
     claims, actions, suits, arbitrations, proceedings or investigations pending
     (or, to our knowledge, overtly threatened in writing) against the Parent or
     the Acquisition Subsidiary, and there are no outstanding court orders,
     court decrees, or court stipulations to which the Parent or the Acquisition
     Subsidiary is a party or by which any of their respective assets are bound,
     any of which (a) if adversely determined would materially restrict or
     interfere with the Agreement or the transactions contemplated thereby, or
     (b) materially restrict the present business properties, operations,
     prospects, assets, revenues or condition (financial or otherwise) of the
     Parent or the Acquisition Subsidiaries, or (c) would, individually or in
     the aggregate, have a Parent Material Adverse Effect or materially impair
     or preclude the Parent's or the Acquisition Subsidiary's ability to
     consummate the Merger or the other transactions contemplated thereby.

Board of Directors
FluoroScan Imaging Systems, Inc.
650-B Anthony Trail
Northbrook, IL 60062


Gentlemen:

     We understand that FluoroScan Imaging Systems, Inc., a Delaware corporation
("FluoroScan" or the "Company"), intends, subject to approval by its Board of
Directors, to enter into an Agreement and Plan of Merger substantially in the
form delivered to us on July 18, 1996 (the "Agreement of Merger") with a newly
formed acquisition corporation, a Delaware corporation (the "Sub"), and a 
wholly-owned subsidiary of Hologic, Inc., a Delaware corporation ("Hologic"),
relating to the proposed merger of the Company with and into Sub (FluoroScan
being the surviving corporation in the merger) (the "Merger") pursuant to which,
among other things: (a) each share of Class A Common Stock, $.0001 par value, of
FluoroScan issued and outstanding immediately prior to the effective time of the
Merger shall be converted into the right to receive 0.31069 shares of Common
Stock of Hologic, $.01 par value, (the "Exchange Ratio"), subject to a price
collar on the Common Stock of Hologic of $30.17 and $50.29 (the "Exchange
Ratio"); (b) each share of Common Stock issued and outstanding immediately prior
to the effective time of the Merger held in Treasury of the Company, by the Sub,
or by Hologic shall be canceled and retired and no payment shall be made with
respect thereto; and (c) all options, whether vested or unvested, to purchase
FluoroScan Common Stock and all options to purchase Company units then
outstanding shall be assumed by Hologic as provided in the Agreement of Merger.

     The Merger is expected to be considered by the stockholders of the Company 
at a special meeting of stockholders and to be consummated on or shortly after 
the date of such meeting.

     You have asked for our opinion, as investment bankers, as to whether the 
Exchange Ratio is fair to the holders of FluoroScan Common Stock from a
financial point of view.

     Rodman & Renshaw, Inc., as part of its investment banking business, is 
regularly engaged in the valuation of businesses and their securities in 
connection with mergers and acquisitions, negotiated underwritings, secondary 
distributions of listed and unlisted securities, private placements and 
valuations for estate, corporate and other purposes. We have acted as financial 
advisor to the Board of Directors of FluoroScan in connection with the Merger, 
have received fees for financial advisory services upon the execution of the 
Agreement of Merger and the

delivery of this opinion and will receive an additional fee contingent upon the 
consummation of the Merger.

        In arriving at the opinion set forth below, with respect to FluoroScan,
we have, among other things: (a) reviewed, from a financial point of view, the
Agreement of Merger and the annexes thereto; (b) studied the Annual Reports to
Stockholders and Annual Reports on Form 10-KSB for the years ended December 31,
1994 and 1995 and its interim reports on Form 10-QSB and 8-K filed since July
11, 1994; (c) reviewed certain publicly available financial and operating data
relating to FluoroScan's business and prospects, which historical information
and data the management of FluoroScan has represented to us as fairly presenting
the financial condition and operating results of FluoroScan as of the dates
presented and, with respect to the prospects of FluoroScan, as being reasonable
evaluations of FluoroScan's prospects; (d) discussed certain financial
information and the business and prospects of FluoroScan with its senior
management; (e) reviewed the reported historical and recent market prices and
trading volumes of the FluoroScan Common Stock; (f) compared the financial,
operating and stock price performance of FluoroScan with certain other companies
deemed comparable; (g) reviewed the financial terms, to the extent publicly
available, of certain other acquisition transactions deemed comparable; and (h)
made such other analyses and examinations as we deemed necessary or appropriate.
With respect to Hologic, we have, among other things: (a) studied the Annual
Reports to Stockholders and Annual Reports on Form 10-K for the years ended
September 25, 1993 September 24, 1994 and September 30, 1995 and its interim
reports on Form 10-Q and 8-K filed since September 25, 1993; (b) reviewed
certain publicly available financial and operating data relating to Hologic's
business and prospects, which historical information and data the management of
Hologic has represented to us as fairly presenting the financial condition and
results of operations of Hologic as of the dates presented and, with respect to
the prospects of Hologic, as being reasonable evaluations of Hologic's
prospects; (c) discussed certain financial information and the business and
prospects of Hologic with its senior management; (d) reviewed the reported
historical and recent market prices and trading volumes of the Hologic Common
Stock; (e) compared the financial, operating and stock price performance of
Hologic with certain other companies deemed comparable; and (f) made such other
analyses and examinations as we deemed necessary or appropriate. We also have
taken into account our assessment of economic, market and financial conditions
generally and within the industry in which FluoroScan and Hologic are engaged.

        In rendering our opinion, we have assumed and relied upon the accuracy
and completeness of all information supplied or otherwise made available to us
by FluoroScan and Hologic or obtained by us from other sources, and we have
relied upon the representations of respective management of FluoroScan and
Hologic that they are unaware of any information or facts that would make the
information provided to us incomplete or misleading. We have not independently
verified such information, undertaken an independent appraisal of the assets or
liabilities (contingent or otherwise) of FluoroScan or Hologic or have been
furnished with any such appraisals. With respect to the publicly available
financial forecasts with regard to each of FluoroScan and Hologic which we have
reviewed, we have relied on the representations of the respective management of
FluoroScan and Hologic that such available forecasts were reasonable and that:
(a) as to the respective forecasts, they are unaware of any facts that would
make such information incomplete, in any material respect, or misleading; and
(b) there have been no material adverse developments in

the business condition (financial or otherwise) or prospects of FluoroScan or 
Hologic, respectively, since each company's most recent fiscal year end.  We 
also have assumed, on the basis of advice from FluoroScan's independent public 
accountants and counsel, that the Merger will be treated as a pooling of 
interests in accordance with generally accepted accounting principles and as a 
tax free reorganization for Federal income tax purposes.

        Our opinion is necessarily based on economic, market and other 
conditions as they exist, and the information made available to us, as of the 
date hereof.  We disclaim any undertaking or obligation to advise any person of 
any change in any fact or matter affecting our opinion which may come or be 
brought to our attention after the date of this opinion.  In the performance of 
our financial advisory services, we were not authorized to solicit, and did not 
solicit, interest from any party with respect to the acquisition of FluoroScan 
or any of its assets.  No other limitations were imposed upon us by FluoroScan 
with respect to the investigations to be made or procedures to be followed by us
in rendering our opinion.

        The opinion expressed herein does not constitute a recommendation as to 
any action the Board of Directors or any stockholder of FluoroScan should take 
in connection with the Merger.  We have expressed no opinion as to the value of 
the securities of Hologic to be issued to holders of FluoroScan Common Stock 
upon consummation of the Merger, or the prices at which such securities may 
trade at any time.  Further, we express no opinion herein as to the structure, 
terms or effect of any other aspect of the Merger, including, without 
limitation, the tax consequences thereof.

        It is understood that this letter is for the information of the Board of
Directors of FluoroScan in connection with its evaluation of the fairness, from 
a financial point of view, as of the date hereof, of the Exchange Ratio to the 
holders of FluoroScan Common Stock and for inclusion in the Joint Proxy 
Statement of FluoroScan and Hologic relating to the Merger.  Without limiting 
the foregoing, in rendering this opinion, we have not been engaged to act as an 
agent or fiduciary for FluoroScan's common stockholders or any other third 
party.

        Based on and subject to the foregoing, we are of the opinion that the 
Exchange Ratio is fair to the holders of Common Stock of FluoroScan from a 
financial point of view.


                                        Very truly yours,


                                        RODMAN & RENSHAW, INC.

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  Article 10 of the Registrant's Certificate of Incorporation eliminates the
personal liability of directors to the Registrant or its stockholders for
monetary damages for breach of fiduciary duty to the extent permitted by the
Delaware General Corporation Law. Article VII of the Registrant's By-Laws
provides that the Registrant shall indemnify its officers and directors to the
extent permitted by the Delaware General Corporation Law. Section 145 of the
Delaware General Corporation Law authorizes a corporation to indemnify
directors, officers, employees or agents of the corporation if such party
acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interest of the corporation and, with respect to any
criminal action or proceeding, had no reason to believe his conduct was
unlawful, as determined in accordance with the Delaware General Corporation
Law. Section 145 further provided that indemnification shall be provided if
the party in question is successful on the merits or otherwise. The Registrant
has also entered into indemnification agreements with each of its directors.
The indemnification agreements are intended to provide the maximum protection
permitted by Delaware law with respect to indemnification of directors. The
Company may also enter into similar agreements with certain of its officers
who are not also directors. The effect of these provisions is to permit
indemnification by the Registrant for liabilities arising under the Securities
Act of 1933, as amended. The Registrant also maintains directors and officers
liability insurance.

ITEM 22. UNDERTAKINGS.
 
  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions described in Item 20 above, or
otherwise, the Registrant has been advised that in the opinion of the
Commission such indemnification is against public policy as expressed in the
Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question of
whether such indemnification by it is against public policy as expressed in
the Act and will be governed by the final adjudication of such issue.
 
  The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act that is incorporated by reference in this Registration Statement
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.
 
  The Registrant hereby undertakes as follows:
 
    (1) That prior to any public reoffering of the securities registered
  hereunder through use of a prospectus which is part of this Registration
  Statement, by any person or party who is deemed to be an underwriter within
  the meaning of Rule 145(c), the Registrant undertakes that such reoffering
  prospectus will contain the information called for by the applicable
  registration form with respect to reofferings by
 
                                     II-3
<PAGE>
 
  persons who may be deemed to be underwriters in addition to the information
  called for by the other Items of the applicable form.
 
    (2) That every prospectus (i) that is filed pursuant to paragraph (1)
  immediately preceding, or (ii) that purports to meet the requirements of
  section 10(a)(3) of the Securities Act of 1933 and is used in connection
  with an offering of securities subject to Rule 415, will be filed as a part
  of an amendment to the registration statement and will not be used until
  such amendment is effective, and that, for purposes of determining any
  liability under the Securities Act of 1933, each such post-effective
  amendment shall be deemed to be a new registration statement relating to
  the securities offered therein, and the offering of such securities at the
  time shall be deemed to be the initial bona fide offering thereof.
 
  The undersigned Registrant hereby undertakes to deliver or cause to be
delivered with the prospectus, to each person to whom the prospectus is sent
or given, the latest annual report to securityholders that is incorporated by
reference in the prospectus and furnished pursuant to and meeting the
requirements of Rule 14a-3 or Rule 14c-3 under the Exchange Act; and, where
interim financial information required to be presented by Article 3 of
Regulation S-X is not set forth in the prospectus, to deliver, or cause to be
delivered to each person to whom the prospectus is sent or given, the latest
quarterly report that is specifically incorporated by reference in the
prospectus to provide such interim financial information.
 
  The Registrant hereby undertakes to respond to requests for information that
is incorporated by reference into the prospectus pursuant to Items 4, 10(b),
11 or 13 of this Form within one business day of receipt of such request, and
to send the incorporated documents by first class mail or other equally prompt
means. This includes information contained in documents filed subsequent to
the effective date of the Registration Statement through the date of
responding to the request.
 
  The Registrant hereby undertakes to supply by means of a post-effective
amendment all information concerning a transaction, and the company being
acquired involved therein, that was not the subject of and included in the
Registration Statement when it became effective.

  RE: Registration Statement on Form S-4 of Hologic, Inc. 
      --------------------------------------------------------------------------
          
   
Ladies and Gentlemen:

     We have acted as counsel to Hologic, Inc., a Delaware corporation (the
"Company"), in connection with the preparation and filing with the Securities
and Exchange Commission of a Registration Statement on Form S-4 (the
"Registration Statement") pursuant to which the Company is registering under the
Securities Act of 1933, as amended (the "Act"), a total of 1,454,901 shares of
common stock, $.01 par value per share (the "Common Stock").  Pursuant to the
Registration Statement and an Agreement and Plan of Merger dated July 18, 1996
(the "Merger Agreement") by and among the Company, FluoroScan Imaging Systems,
Inc. ("FluoroScan") and Fenway Acquisition Corp., in the form filed as Exhibit
2.01 to the Registration Statement, the Company proposes to issue to the holders
of FluoroScan common stock, $.0001 par value per share, up to 1,454,901 shares
of Common Stock (the "Shares").  This opinion is being rendered in connection
with the filing of the Registration Statement.  Unless otherwise indicated,
capitalized terms used herein shall have the meanings ascribed thereto in the
Merger Agreement.

     For purposes of this opinion, we have assumed, without any investigation,
(i) the legal capacity of each natural person, (ii) the full power and authority
of each entity and person other than the Company and Fenway Acquisition Corp. to
execute, deliver and perform each document heretofore executed and delivered or
hereafter to be executed and delivered and to do each other act heretofore done
or hereafter to be done by such entity or person, (iii) the due authorization by
each entity or person other than the Company and Fenway Acquisition Corp. of
each document heretofore executed and delivered or hereafter to be executed and
delivered and to do each other act heretofore done or to be done by such entity
or person, (iv) the due execution and delivery by each entity or person other
than the Company and Fenway Acquisition Corp. of each document heretofore
executed and delivered or hereafter to be executed and delivered by such entity
or person, (v) the legality, validity, binding effect and enforceability as to
each entity or person other than the Company and Fenway Acquisition Corp. of
each document heretofore executed and delivered or hereafter to be executed and
delivered and of each other act heretofore done or
<PAGE>
 
     hereafter to be done by such entity or person, (vi) the genuineness of each
signature on, and the completeness of each document submitted to us as an
original, (vii) the conformity to the original of each document submitted to us
as a copy, (viii) the authenticity of the original of each document submitted to
us as a copy, (ix) the completeness, accuracy and property indexing of all
governmental and judicial records searched and (x) no modification of any
provision of any document, no waiver of any right or remedy and no exercise of
any right or remedy other than in a commercially reasonable and conscionable
manner and in good faith.

     In connection with this opinion, we have examined the following
(collectively, the "Documents"):

     (i)   the Certificate of Incorporation of the Company incorporated by
           reference as Exhibit 3.01 to the Registration Statement;
     (ii)  the By-laws of the Company incorporated by reference as Exhibit 3.02
           to the Registration Statement;
     (iii) the corporate minute books or other records of the Company;
     (iv)  a specimen certificate for the Common Stock incorporated by reference
           as Exhibit 4.01 to the Registration Statement; and
     (v)   the Merger Agreement.

     The opinions expressed herein are based solely upon (i) our review of the
Documents, (ii) discussions with S. David Ellenbogen, the Chairman of Board and
Chief Executive Officer of the Company and Glenn P. Muir, the Company's Vice
President of Finance and Treasurer; (iii) the representations and warranties of
the Company, Fenway Acquisition Corp. and FluoroScan contained in the Merger
Agreement and the schedules and exhibits thereto, (iv) discussions with those of
our attorneys who have devoted substantive attention to the matters contained
herein, and (v) such review of published sources of law as we have deemed
necessary.

     Our opinions contained herein are limited to the laws of The Commonwealth
of Massachusetts, the general corporate laws of the State of Delaware and the
federal law of the United States of America.

     Based upon and subject to the foregoing, we are of the opinion that:

     The Shares to be issued by the Company under the circumstances contemplated
in the Registration Statement are duly authorized and, when delivered pursuant
to the Merger Agreement, will be validly issued, fully paid and nonassessable.
<PAGE>
 
     We understand that this opinion is to be used in connection with the
Registration Statement.  We consent to the filing of this opinion as an Exhibit
to said Registration Statement and to the reference to our firm wherever it
appears in the Registration Statement, including the prospectuses constituting a
part thereof and any amendments thereto.  This opinion may be used in connection
with the offering of the Shares only while the Registration Statement, as it may
be amended from time to time, remains in effect.

                         Very truly yours,

                         BROWN, RUDNICK, FREED & GESMER
