                                  WITNESSETH:

     WHEREAS, the parties hereto presently are all affiliates of each other;

     WHEREAS, each party hereto uses certain names, trademarks and other
intellectual property owned by other of the parties hereto and may use
certain services, facilities, products and related items of other of the
parties hereto; and

<PAGE>

     WHEREAS, the parties hereto desire to confirm by a written agreement the
arm's-length terms and conditions under which all such use has taken place and
shall take place in the future;

     NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants contained herein, the parties hereto hereby agree as follows:

     1.0  DEFINITIONS

          1.1  "Affiliate" shall mean any person or entity which, directly or
indirectly, controls a party hereto, or is controlled by a party hereto, it
being understood that for such purposes "control" shall mean possession,
directly or indirectly, of the power to direct or cause the direction of the
management and policies of such person or entity, whether through the
ownership of voting securities or by contract or otherwise.

          1.2  "Change of Control" shall mean, with respect to any party
hereto, a change in the possession to a third party who is presently not an
Affiliate, directly or indirectly, of the power to direct or cause the
direction of the management of policies of such party, whether through a
change in the ownership of voting securities or by contract or otherwise
which occurs prior to completion of a public offering of at least $25,000,000
(twenty five million dollars) on a well-established public stock market (e.g.
NASDAQ, Neuer Markt, or others). An initial public offering and transfer of
control of a party to public ownership shall specifically not constitute a
Change of Control.

          1.3  "Intellectual Property" shall mean all patents, patent
applications, inventions, trademarks, trademark applications, copyrights,
copyright applications, trade secrets, common law rights and other
intellectual property rights of any nature whatsoever in existence as of the
Date of the Agreement, provided, however, that in the

<PAGE>

case of any patents and patent applications of Bruker Daltonics, only those
patents and patent applications listed on Attachment B shall be included in
Intellectual Property.

          1.4  "Lien" shall mean, with respect to any item, any mortgage,
deed of trust, pledge, hypothecation, assignment, security interest, lien,
charge, restriction, adverse claim by a third party, title defect or
encumbrance of any kind.

          1.5  The "Name" shall mean the name "BRUKER", any logos associated
therewith, and all Intellectual Property rights related thereto together with
all goodwill associated therewith.

     2.0  NAME

          2.1  The parties acknowledge that BA-DE owns the entire right,
title and interest in and to the Name in Germany, as well as various
international countries listed in Attachment A. The parties acknowledge that
BPAG-DE owns the entire right, title and interest in and to the Name in the
U.S., Israel and the rest of the world, except where the rights to the Name
are specifically owned by BA-DE.

          2.2  BA-DE and BPAG-DE hereby confirm that the other parties have
properly used the Name prior to the date hereof.

          2.3  BA-DE and BPAG-DE hereby grant the other parties hereto a
perpetual, irrevocable, non-exclusive, royalty-free, non-transferable right
and license to use the Name in connection with the conduct and operation of
the business, as the same may be conducted from time to time, of each such
party, subject to and in accordance with the following:

               2.3.1  Each party shall use the Name in such a manner that it
does not interfere with any other party's use of the Name. Moreover, all
parties hereto have or


<PAGE>

will endeavour to adopt additional names in conjunction with the Name Bruker
to identify clearly the scope and purpose of each autonomous business (e.g.
Bruker Optics, Bruker Daltonics, Bruker AXS, Bruker Medical, etc.)

               2.3.2  No party shall at any time, directly or indirectly,
take any material action which materially detracts from the goodwill
associated with the Name.

               2.3.3  Notwithstanding the irrevocable, perpetual nature of
the license set forth in this Section 2.3, for ten (10) years after the
signing of this Agreement, a Party's license under this Section 2.3 may
become null and void at the option of BPAG-DE and BA-DE, which option must be
exercised in writing within ninety (90) days of the occurrence if a party (a)
files a voluntary petition for bankruptcy, (b) has an involuntary petition
for bankruptcy filed against it which remains undismissed for at least sixty
(60) consecutive days, (c) fails to comply with the provisions of this
Section 2.3, (d) suffers a major loss of its reputation in its industry or
marketplace, such as by the distribution of defective, harmful, illegal, or
dangerous goods or merchandise which materially detracts from the goodwill
associated with the Name, or (e) undergoes a Change of Control. Provided,
however, that each party hereto which may receive such written notice under
this section, shall be given a ninety (90) day period after receipt of
written notice to cure the problem or occurrence which led to the notice.

               2.3.4  While the license set forth in this Section 2.3 is
non-transferable, a party shall have the right to have its Affiliates use the
Name subject to and in accordance with the following:

                    2.3.4.1  Use by an Affiliate shall be subject to all the
conditions of this Section 2.3.


<PAGE>

                    2.3.4.2  The party to this Agreement which permits its
Affiliate to use the Name shall be fully responsible under this Agreement for
the use of the Name by such Affiliate.

               2.3.5  No party shall take any action which would cause a Lien
to be placed on the Name or on a party's license rights under this Section
2.3.

          2.4  In the event a party at any time believes a person or entity
not a party to this Agreement is infringing the Name or in the event any
party's use of the Name at any time leads to a claim that it is infringing
the rights of a third party, the parties hereto will work together and
cooperate in good faith with respect to the handling of such matter. The
financial burden of enforcing the rights in the Name will be shared equitably
between the parties hereto.

     3.0  TECHNOLOGY

          3.1  The parties acknowledge that each party hereto (a) owns
various technology and the Intellectual Property relating thereto, and (b)
has used and uses the technology and Intellectual Property of other parties
hereto, provided, however, that use of the patents and patent applications
included in such Intellectual Property by each party hereto (other than use
pursuant to the separate written agreements referred to in Section 3.3 below)
is limited to use of these patents and patent applications as it is in effect
prior to the Date of the Agreement, and (c) that the Bruker Daltonics patents
and patent applications described in Schedule B are used only by those parties
specified as using such patents and patent applications in such Schedule B.

          3.2  Each party confirms that the other parties hereto have
properly used its technology and related Intellectual Property prior to the
date hereof.

<PAGE>


          3.3  Each party acknowledges that certain specific written
agreements are in place between certain parties hereto defining the use,
royalties and terms and conditions of use of technology and related
intellectual property between the specific parties to such separate
previously existing written agreements. This Agreement shall not supersede or
replace any existing written agreements pertaining to the subject matter
hereof. For all technology and related intellectual property which is not
governed by a specific separate written agreement between the parties or
between any one or more parties and a third party, each party hereby grants
each of the other parties hereto a perpetual, irrevocable, non-exclusive,
royalty free, non-transferable right and license to use the technology and
related Intellectual Property of the granting party in connection with the
conduct and operation of the business, as the same may be conducted from time
to time, of each such other party, unless such other party hereto undergoes a
Change of Control, subject to and in accordance with the following:

               3.3.1  In the event a party (the "First Party") desires
to make a broader use of the technology or Intellectual Property of another
party (the "Second Party") hereto than the use of such Intellectual Property
by the First Party as of the Date of this Agreement, the two parties shall
negotiate in good faith regarding the possibility of entering into a written
agreement permitting the First Party to make such broader use, on arm's
length terms and conditions such as would be utilized in a typical
transaction with a person or entity not a party to this Agreement, provided,
however, that neither the First Party nor the Second Party shall have any
obligation to enter into any such agreement.

               3.3.2  No party (the "First Party") shall at any time
take any


<PAGE>

action which would materially adversely affect the value of any technology or
Intellectual Property of any other party hereto, which has been made
available to the First Party hereunder.

               3.3.3  Each party shall use the technology and Intellectual
Property of the other parties in such a manner that it does not materially
interfere with any other party's use thereof.

               3.3.4  While the license set forth in this Section 3.3. is
non-transferable, a party shall have the right to have its Affiliates use the
technology or Intellectual Property of another party hereto subject to and in
accordance with the following:

                    3.3.4.1  Use by an Affiliate shall be subject to all of
the conditions of this Section 3.3.

                    3.3.4.2  The party to this Agreement which permits its
Affiliate to use the technology or Intellectual Property of another party
shall be fully responsible for the use thereof by such Affiliate.

               3.3.5  No party shall take any action which shall cause a Lien
to be placed on the technology or Intellectual Property of another party
hereto or on such party's license rights under this Section 3.3.

          3.4  In the event a party at any time believes a person or entity
not a party to this Agreement is infringing the technology or Intellectual
Property of any party to this Agreement or in the event any party's use of
the technology or Intellectual Property of a party to this Agreement at any
time leads to a claim that such using party is infringing the rights of a
third party, the party which owns such technology or Intellectual Property
will be responsible for the handling of such matter, provided that such owning

<PAGE>

party shall receive reasonable cooperation in connection therewith from the
other parties hereto which use such technology or Intellectual Property.

     4.0  DISTRIBUTION

          4.1  The parties acknowledge that prior to the date hereof they
have used, and may continue to use after the date hereof, selected common
distribution channels for their respective products, including through the
Affiliates of the parties hereto.

          4.2  Such common distribution channels shall continue, and no party
shall take any action which would interfere with the right of any other party
hereto to use such distribution channels.

          4.3  The terms and conditions of sale and the transfer pricing for
such distribution will be on an arm's length basis as would be utilized in a
typical transaction with a person or entity not a party to this Agreement.

          4.4  No common sales channel shall have any exclusivity in any
country or other geographic area and any party hereto shall have the right to
establish its own subsidiary sales channel or third-party sales channels in
any country or other geographic area at any time for any reason. However, in
this case sixty (60) days written notice shall be given.

          4.5  In addition to the ability to establish a new sales channel as
described in Section 4.4 hereof, a party hereto shall have the right at any
time to establish additional exclusive or non-exclusive sales channels in any
country, geographic area or market segment with sixty (60) days written
notice.
