BETWEEN:

registered with the Registry of Commerce and Companies of Nanterre under number
B 349 961 607 RCS d'Evry, represented by Mr. Muir, legal representative duly
authorized,

(hereafter, the "Employer"),

                                                                ON THE ONE HAND,

AND

Mr. Jean Chaintreuil, born on March, 1955, a French Citizen, residing36, rue du
General Brunet, 75019 Paris,

(hereafter the "Employee"),

                                                              ON THE OTHER HAND.

PREAMBLE:

A.   The employee was hired by the Hologic France SA, Hologic Europe N.V,
Hologic Espana S.A. as a General Manager/ President European Operations pursuant
to an indefinite term employment agreement dated October 1, 1991, with a monthly
gross salary amounting to FRF 36.667,00 (EUR 5589,85) and a variable
compensation in consideration of the achievement by the Employee of objectives
defined in the annex B of the employment agreement.

Under Annex C of his employment contract, the Employee is bound by a
non-competition undertaking, which is applicable both during and after the
termination of his employment contract.

At the same time, the Employee was a corporate officer in his capacity as
President of Hologic France and as legal representative ("Administrateur
Delegue") of Hologic Europe N.V and as President and a corporate officer of
Hologic Espana S.A..

B.   As General Manager/ President European Operations, the Employee was in
charge of the management of the sales teams and ensuring the reporting of the
sales forecast relating to the product line he was in charge of in Europe.

<PAGE>

C.   Since the new reorganization decided by the Group, the Employee indicated
to the Employer his disagreement on the essential points of the commercial
policy decided by the company and that he must apply in Europe.

The Employee put into question the commercial plans for which the group gave him
management responsibility.

The Employee criticized, several times, the reorganization plan for the European
team stating that the reduction and the redeployment of the staff did not permit
him to assure the commercial development objectives of the group.

In general, it appears that the Employee was reluctant to apply the decisions of
the group in a context in which it is important that the management team fully
back company policy.

This criticisms regarding the commercial plans for Europe created a discord with
the other managers and demotivated his staff.

Considering the position of the Employee and the highly competitive business in
which the company operates, this situation could not continue.

D.   Considering this situation, the Employee, decided to resign from his
position as an employee of Hologic Europe N.V and Hologic Espana S.A by two
letters dated January 15th, 2002 in which he asked to be exempted from working
during his notice period. Hologic Europe N.V and Hologic Espana S.A have agreed
to exempt the Employee from working during his notice period.

E.   The situation between the parties became difficult and the Employer
convened the Employee to a preliminary interview scheduled on January 21, 2002
by a letter duly handed to Employee.

During the preliminary interview on January 29, 2002, the Employer explained the
reasons why it was considering dismissing the Employee.

The Employer considered that the explanations given by the Employee were not
satisfactory and, therefore, the Employer notified the Employee, by registered
mail dated February, 1st 2002, of his dismissal for disagreement on the
essential points of the commercial policy of the company, which created
disagreement with the other managers and demotivated his employees.

The Employer also informed the Employee that it would provide him, at the end of
the notice period, with a Labor Certificate ("Certificat de Travail"), an
Unemployment Attestation ("Attestation Assedic") and the full amount remaining
due to him against written receipt ("Recu pour Solde de tout Compte").

The Employee was also notified that he must respect his contractual
confidential, discretion and non-competition undertakings.

                                                                               2

F.   The Employee immediately contested the reasons for his dismissal arguing
that his dismissal was unfair and wrongful and that the Employer did not comply
with the legal rules regarding dismissal procedures.

First, the Employee considered that his dismissal was invalid because his
dismissal letter was signed by a person who had did not have authority to
represent the Employer.

The Employee considered also that his dismissal letter was not duly notified
pursuant to the legal requirements, which provide that the dismissal letter
should be sent by registered letter with acknowledgment receipt.

The Employee added that the Employer violated the terms of his employment
agreement, the annex and the exhibits.

The Employee considered also that the dismissal based on disagreement on the
essential points of the commercial policy of the company was without basis and
that there was only a disagreement on minor points.

The Employee considered that he has simply exercised his right of expression,
which the law and the case law recognize as a legal right.

The Employee added that the Employer did not demonstrate that this so-called
disagreement on the essential points of the commercial policy of the company had
disturbed, in any way, the proper functioning of the company.

The Employee added that the demotivation of his staff and the resulting internal
tensions were the consequences of the group reorganization and not due to his
opinion.

G.   The Employee asserted that his dismissal was based, in reality, on economic
grounds and was not for personal cause.

Therefore, the Employee considered that his dismissal for personal cause was
decided by the Employer in order not to comply with the specific procedures for
economic dismissals and that the true reason for his dismissal was the decision
of the Employer to replace qualified and senior employees by new employees
having lower salaries.

The Employee stated that the Employer violated the legal requirements concerning
economic dismissals and case law regarding outplacement, as well as the ordered
of dismissal rules.

Moreover, the Employee stated that the measures taken against him were very
brutal and offensive.

Furthermore, the Employee added that the Employer did not comply with the legal
rules regarding dismissal procedures and with its obligations under the terms of
the employment agreement and concerning the amounts remaining due to him.

H.   Under these conditions, the Employee asserted that, considering the
procedures used, the fact that his dismissal was unfair and considering the
violation by the Employer of its obligations under the terms of the employment
agreement and the contractual documents, he suffered important moral, financial
and professional prejudice given his age (46 years old

                                                                               3

when his was dismissed), family responsibilities and professional career which
will necessarily be affected by the decision of the Employer to put an end to
his employment agreement.

The Employee indicated that because of his age (46 years old) he would probably
not find a new job after his dismissal.

The Employee added that the damage caused to him was all the more important
since the government unemployment allocations are digressive and his dismissal
would also came him to lose his complementary retirement points, so that the
amount of his complementary pension would substantially decrease.

Lastly, the Employee indicated that because of his senior position his dismissal
had an impact on his reputation, both from a professional and personal point of
view.

Consequently, the Employee indicated to the Employer that he intended to bring
legal action before the labor court in order to obtain damages.

I.   The Employer argued that it had complied with the legal rules regarding
dismissal procedures and that the dismissal was completely justified by a
disagreement on the essential points of the commercial policy of the company
which had a negative impact on other managers and staff.

The Employer indicated that the grounds for the dismissal were real and serious
and could be verified.

The Employer considered that the disagreement with and the behavior by the
Employee resulted in a demotivation of his staff and also created tension inside
the company disturbing the functioning of the company.

The Employer considered that the criticism of the Employee exceeded the right of
executive expression.

The Employer confirmed that it fully respected the procedural rules.

The Employer considered that the person who signed the letters concerning the
dismissal and who was present during the preliminary interview had all necessary
authority to represent the Employer.

J.   A disagreement therefore exists between the Employee, on the one hand, and
the Employer, on the other hand.

Discussions therefore took place, after which the parties, with their counsel,
in order to resolve the disagreements arising from the dismissal of the Employee
and his claims for damages, an indemnity, payment of additional salary and other
amounts, reached an agreement, pursuant Articles 1134 and 2044 to 2058 of the
Civil Code, and made reciprocal concessions in order to avoid the cost,
uncertainty and the adverse publicity of litigation, and agreed to put an end to
their dispute without restriction or limitation.

                                                                               4
