1.0 PURPOSE

This Exhibit A defines the tasks to be performed by LMF, the deliverable items
and delivery schedule for the LDI Detector development.

2.0 APPLICABLE DOCUMENTS

The following documents of the exact issue form part of this Exhibit A to the
extent that they are referenced herein:

Quality Requirements:      ISO-9000

3.0 REQUIREMENTS

3.1 ELECTRONICS DESIGN APPROACH

The CCD sensor will be mounted in a [**] housing with approximately [**] (to
be confirmed) [**] feedthroughs. Within the housing, the feedthroughs connect
to a [**] which connects the [**] to the sensor.

The feedthroughs connect to the [**] which will be attached to the [**]
enclosure. The [**] will house [**] (to be confirmed) [**].

This design approach of the [**] allows for a [**]. To reduce development
time, LMF will adapt an existing [**] and an existing [**] for this project.
The [**] will require changes to its [**] and firmware changes to its [**].
The [**] will require changes to [**] to allow for different [**].

The other [**] will require new design and development. In developing this
system, the main emphasis is to design the [**] such that the main component
of [**] is dominated by the [**] from the [**]. Thus, the most crucial [**]
is the [**]. The other [**] and [**] and [**] play an important role in the
system design, but are mainly based on [**].

[**] Indicates that information has been omitted and filed separately with the
Commission pursuant to a request for confidential treatment.

                                     - 19 -

3.2 SENSOR OPERATION

In order to maximize system performance, the [**] and [**] must be optimized.
In this application, the [**] is defined as the [**]. Ideally, this [**]
would be at least [**] with a [**] of less than [**]. Since it appears that
dramatic improvements in the [**] appear limited at this time, the [**] is
assumed [**]. The current test system, based on measurement made on a similar
[**] should have a [**] of approximately [**]. Therefore, to meet the [**]
requirements for [**], the [**] would ideally be at most [**].

[**] will be employed for two reasons. The first is that this will [**] the
[**] so that the [**] is limited to within [**]. The second reason is to [**]
the [**]. This, in turn, [**] the [**] which is important to maximize
efficiency [**].

The [**] has [**] outputs. In order to [**] the [**] required for any single
[**], all [**] outputs will be utilized [**]. This will [**] for each [**] of
what would otherwise be required. This will [**], but also the [**] since [**].

The other major component of [**] is [**]. In addition to the use of [**]
outputs, the [**] will be [**] to [**] the [**] to an acceptable level. With
sufficient [**], the [**] can also be [**].

                              GKSS No. P3.3.02.F.02

                                    regarding

               the Purchase of Gradient Multi-layer X-ray Mirrors

CONFIDENTIAL TREATMENT HAS BEEN REQUESTED AS TO CERTAIN PORTIONS OF THIS
EXHIBIT, WHICH PORTIONS HAVE BEEN OMITTED AND REPLACED WITH [**] AND FILED
SEPARATELY WITH THE COMMISSION.

<PAGE>

1.       CONTRACT PRODUCTS

         "Contract products" are the X-ray mirrors defined in APPENDIX 1 to this
         Contract.

         GKSS agrees not to sell contract products to third parties. AXS agrees
         to make contract products available to the market at unfair [SIC]
         conditions.

2.       ORDERS

2.1      GKSS shall supply AXS on the basis of individual purchase orders
         ("orders") according to the conditions of this Contract.

2.2      Each order shall list the necessary information, such as item delivered
         (type of mirror, parameters, and quantity), delivery date, and contract
         number. GKSS shall immediately confirm each order in writing.

2.3      Unless otherwise expressly agreed in this Contract or in the respective
         order, the AXS terms and conditions of orders Appendixed to this
         Contract as APPENDIX 2 shall apply to orders. General GKSS terms and
         conditions of business that differ from the aforementioned terms and
         conditions shall not apply.

2.4      The prices established in APPENDIX 3 of this Contract shall be used as
         a basis for calculating charges; these are fixed prices until September
         30, 1999. Changes in price shall be made by mutual agreement and
         specified in writing. GKSS is prepared to renegotiate the prices in the
         event of an increase in the ordered quantity or a reduction of the
         market price.

2.5      Delivery shall be ex works, including packaging. GKSS shall ensure that
         the contract products are packed with consideration of all normal
         transportation risks.

2.6      Payment shall be made within 30 (thirty) days after delivery and upon
         receipt and verification of the invoice.

2.7      The delivery time for orders less than or equal to 15 units shall be 6
         (six) weeks, beginning with receipt of the commercially and technically
         cleared order by GKSS and confirmation of the order by GKSS. GKSS shall
         confirm the commercially and technically cleared order within two (2)
         weeks. The delivery period for subsequent orders shall be six (6) weeks
         after the delivery of each previous order.

3.       REQUIREMENTS FORECAST

         AXS shall first determine its projected needs for the contract products
         over a period of 12 (twelve) months, beginning on the effective date of
         this Contract.

<PAGE>

         This requirements forecast shall be adjusted and updated quarterly for
         each subsequent 12 (twelve) month period (revolving requirements
         forecast). The requirements forecast is intended to ensure the fewest
         interruptions in product deliveries to AXS and shall have no binding
         effect.

4.       RIGHT TO EMERGENCY PRODUCTION

4.1      GKSS recognizes that the continuous availability of the contract
         products is of the utmost importance to AXS. To ensure the continuous
         availability of the contract products for AXS, GKSS and AXS agree upon
         a right to emergency production as stipulated in Item 4.2 below.

4.2      If and to the extent that GKSS for any reason ceases production of the
         contract products or fails to fulfill its delivery obligations for a
         period of more than one (1) month, AXS may demand that GKSS enable AKS
         (particularly through the immediate provision by GKSS of technical
         information and documents, including software, needed for the
         production and testing of the contract products) to manufacture the
         contract products itself or to have contract products manufactured and
         distributed for it, and that GKSS grant the necessary rights (including
         relevant patent rights of GKSS).

         If the right to emergency production is exercised, then GKSS shall be
         entitled to an appropriate licensing fee for the use of its technical
         information and documents/software-programs and/or patent rights.

         In the event that it exercises its right to emergency production, AXS
         may require that GKSS make available at appropriate terms and
         conditions any special tools and/or equipment that would otherwise be
         unobtainable. If GKSS is unable to comply with this requirement, then
         it shall enable AXS to construct copies these special tools and/or
         equipment to the extent possible.

4.3      The right to emergency production shall end as soon as the circumstance
         requiring the right to emergency production has been permanently
         rectified. If a third party is used during emergency production, then
         this third party shall be required to enter into a confidentiality
         agreement.

         In the event of delay or inability to comply, any existing legal claims
         that exceed the terms of Item 4 shall remain unaffected thereby.

5.       WARRANTY AND LIABILITY

5.1      GKSS warrants that the contract products correspond to the
         specifications as defined in APPENDIX 1.

         The warranty period shall be 12 (twelve) months, beginning with
         acceptance of the contract products by AXS. The contract products must
         be accepted no later

<PAGE>

         than eight (8) weeks after delivery by GKSS. If acceptance is not
         expressly refused within this period, then the contract products shall
         be considered as accepted.

         Complaints regarding defects must be promptly communicated to GKSS in
         writing. GKSS shall have the right to choose whether to repair the
         defect or to replace the defective contract product with a
         non-defective contract product within 20 (twenty) working days after
         the defective contract products have been received by GKSS. If the
         defects are not remedied, AXS shall have the right to demand at its
         discretion either a reduction of the price or cancellation of the
         Contract for the delivery about which a complaint has been made. Any
         further warranty claims shall be precluded in this case.

         The warranty period shall be three (3) months for any repaired or
         replaced contract products delivered, although it shall continue at
         least until the expiration of the original warranty period.

5.2      Liability of GKSS, its legal representatives, and its agents due to
         breach of contract or tort shall be limited to willful misconduct,
         gross negligence, lack of a guaranteed quality, and violation of an
         obligation if such violation would endanger the object of the Contract.
         Liability shall be limited to DM 500,000 (five hundred thousand
         Deutsche marks).

5.3      AXS shall indemnify GKSS against all product liability claims made by
         third parties due to faulty contract products.

6.       PROTECTION OF INDUSTRIAL PROPERTY RIGHTS

         If a third party exercises legitimate claims against AXS based upon or
         related to patent rights due to the method of manufacturing the
         contract products, then GKSS shall be obligated to choose between the
         following actions, to be performed at its own expense:

         - to obtain a right of use for AXS from the owner of the patent rights,
           or

         - to change the parts of the contract products relevant to the patent
           rights, or

         - to replace the parts relevant to the patent rights with parts not
           subject to the patent rights, or

         - to take back the corresponding contract products in exchange for a
           refund of the purchase price.

         A prerequisite for this is that AXS must immediately advise GKSS of
         all claims made, as well as all subsequent proceedings.

<PAGE>

         Any further claims resulting from infringement of patent rights owned
         by third parties shall be precluded.

7.       CONFIDENTIALITY

         Each contracting party shall maintain confidentiality regarding
         technical documents and information, as well as special knowledge of
         each other's internal matters, and shall divulge such information to
         third parties only with the explicit consent of the other contracting
         party, if and to the extent that this information is not generally
         known through publication or some other form without breaching this
         obligation of confidentiality.

         Any third parties that may become involved in this Contract must also
         be explicitly subjected to this obligation. This obligation shall
         continue in effect even after termination of this Contract.

8.       CONTRACTUAL PERIOD

         This Contract shall come into effect upon signing.
         AXS shall be obligated to purchase mirrors in a cumulative total volume
         of DM 360,000 during the period of October 1, 1998 to September 30,
         2001. The Contract may be terminated no earlier than September 30, 2000
         with a 12-month period of notice. In the event of this premature
         termination, AXS shall be obligated to purchase mirrors valued at no
         less then DM 240,000.

9.       OTHER PROVISIONS

9.1      No ancillary agreements exist. Changes and additions to this Contract
         must be made in writing.

9.2      Should individual provisions of this Contract be or become invalid,
         then the remaining provisions of this Agreement shall be unaffected
         thereby. In such an event, both sides shall replace the invalid
         provision with a valid provision that achieves the purpose of the
         affected provision to the extent possible. A similar procedure must be
         applied should a loophole become apparent in the course of completing
         the Contract.

9.3      Two (2) copies of the Contract shall be prepared, with each contracting
         party receiving one copy.

APPENDIX 2

                             CONDITIONS OF PURCHASE

I. PURCHASE ORDER AND ORDER CONFIRMATION
(1) Bruker AXS Analytical X-Ray Systems GmbH (purchaser) may cancel the purchase
order if the supplier has not provided written confirmation (order confirmation)
within two weeks after receipt.
(2) If the order confirmation differs from the purchase order, the purchaser
shall be bound only if he has agreed to the difference in writing. Specifically,
the purchaser shall be bound by the supplier's general terms and conditions of
business only to the extent that these terms and conditions are in accordance
with the purchaser's terms and conditions, or if the purchaser agrees to them in
writing. Acceptance of product deliveries or services, as well as payments, do
not constitute an agreement.
(3) Changes or additions to the purchase order shall be valid only if they are
confirmed in writing by the purchaser.

II. DELIVERY TIME
(1) Timeliness of product deliveries shall be determined based upon their
arrival at the receiving location specified by the purchaser, and the timeliness
of product deliveries involving assembly or installation, as well as services,
shall be based upon their acceptance.
(2) In the event of a discernible delay of a product delivery or service, the
purchaser must be notified of this delay immediately and his decision regarding
further action must be obtained.

III. TRANSFER OF RISK, SHIPPING
(1) For services and product deliveries involving assembly or installation, risk
shall be transferred upon acceptance; for product deliveries without setup or
assembly, risk shall be transferred upon their arrival at the receiving location
specified by the purchaser.
(2) Unless otherwise agreed, the supplier shall bear the costs for shipping and
packaging. In the case of pricing ex works or from the supplier's sales
warehouse, shipments must be made at the lowest possible cost in each case,
unless the purchaser has specified a particular mode of shipment. The supplier
shall bear additional costs incurred due to a failure to comply with shipping
regulations. The purchaser may also specify the mode of shipment for pricing
free consignee. The supplier shall bear the additional costs of any accelerated
shipment needed in order to comply with his delivery deadline.
(3) Each delivery shall be accompanied by a packing slip or delivery receipt
containing details of the contents as well as the complete purchase order
identification code. An immediate notification of the shipment must be sent with
this same information.

IV. INVOICES

Invoices must specify the purchase order identification code as well as the
numbers for each individual item. Invoices are not payable so long as this
information is missing. Copies of invoices must be identified as duplicates.

<PAGE>

V. PAYMENTS

(1) Unless otherwise agreed, payments shall be made
within 14 days minus a 3% discount, or within 30 days minus a 2% discount, or
within 90 days net.
(2) The payment period shall begin as soon as the product delivery or service
has been completed and the properly issued invoice has been received. If the
supplier must provide material tests, inspection logs, quality documents, or
other documents, the receipt of these documents shall also be a prerequisite for
the completeness of the product delivery or service. A discount deduction shall
also be permitted if the purchaser offsets or withholds payments in an
appropriate amount due to defects; the payment period shall begin following
complete remedy of the defect or defects.
(3) Payments do not constitute recognition of the products or services as
complying with the Contract.

VI. LIABILITY FOR DEFECTS

(1) The supplier must provide a one-year warranty for his products and services.
The warranty period shall begin with the transfer of risk (Item III, Para. 1).
In the event of product deliveries to locations where the purchaser is
conducting projects outside of his factories or facilities, the warranty period
shall begin with the acceptance by the party for whom the purchaser is
conducting the project or projects. The warranty period shall end no later than
two years following transfer of risk.
(2) If defects are determined before or upon transfer of risk or appear during
the warranty period, then the supplier must bear the costs for either
eliminating the defect or delivering a new non-defective product or service,
based upon the purchaser's choice. This shall also apply to product deliveries
in which inspection is limited to random samples. The purchaser shall make a
decision based upon his own reasonable discretion.
(3) If the supplier fails to remedy the defect or provide a new product delivery
or service within an appropriate time period determined by the purchaser, then
the purchaser shall have the right to withdraw fully or partially from the
Contract without compensation, or to require a reduction of the price, or to
demand that the supplier perform or have performed at his own cost repairs or
new product deliveries, or to demand compensation for nonperformance. This shall
also apply if the supplier declares that he is unable to remedy the defect or to
deliver a new product or service within an appropriate period of time.
(4) Repairs may be performed at supplier's cost without the specification of a
time period if delivery is made following the onset of a delay and the purchaser
has an interest in immediate repair in order to avoid a delay or for other
reasons of urgency.
(5) The rights described above shall expire one year after the defect is
reported.
(6) More extensive legal rights, especially regarding reimbursement of costs for
useless work or processing, shall remain unaffected.

<PAGE>

(7) Complaints regarding defects may be raised within one month of product
delivery or performance of service or, if the defect is noticed only during
work, processing or utilization, with one month from the time that the defect is
detected.
(8) The aforementioned arrangements shall apply similarly for services performed
to remedy defects.
(9) The supplier shall bear the costs and risks for the return of defective
delivered products.

VII. SUBCONTRACTING ORDERS TO THIRD PARTIES

Orders may not be subcontracted to third parties without the written consent of
the purchaser, and such subcontracting shall entitle the purchaser to fully or
partly withdraw from the Contract or to demand compensation for damages.

VIII. MATERIAL PROVIDED BY THE PURCHASER

(1) Material provided by the purchaser shall remain the property of the
purchaser and must be separately stored, marked, and managed at no cost.
Provided material may be used only for the purchaser's orders. The supplier must
compensate the purchaser in the event of depreciation in value or loss. This
shall also apply for the authorized transfer of use of material associated with
the order.
(2) The material shall be processed or transformed for the purchaser. The
purchaser shall become the owner of the new or transformed item. If this is not
possible for legal reasons, then the purchaser and the supplier agree that the
purchaser shall become the owner of the new item at every point in time during
the processing and transformation. The supplier shall store the new item free of
