ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.

         (a) On December 22, 1999, Biomagnetic Technologies, Inc. ("BTi")
         acquired all of the issued and outstanding capital stock ("Shares")
         of Neuromag Oy pursuant to the terms of a Share Purchase Agreement
         by and between Marconi Medical Systems, Inc. ("Marconi") and BTi
         (the "Share Purchase Agreement"). Under the terms of the Share
         Purchase Agreement, BTi paid a total of $10 million in cash to
         Marconi for the purchase of the Shares and agreed to pay between a
         minimum of $2.5 million and a maximum of $5 million in royalties to
         Marconi under a royalty agreement over the next eight years, and
         additional consideration of up to approximately $1.8 million
         dependent upon the occurrence of certain future events.

         The Company has obtained a loan from AIG Private Bank Ltd. totaling $11
         million that is secured by Shares of Neuromag Oy and is guaranteed by
         an entity unaffiliated with the Company. The loan matures June 30,
         2000. Martin Egli, a board member of BTi, also serves on the Board of
         Directors of AIG Private Bank Ltd. As a part of its ongoing financing
         strategies, the Company intends to raise additional capital for the
         purposes of repaying the loan and to continue to fund operations. There
         can be no assurance that the Company will be able to raise such capital
         on terms acceptable to the Company, if at all.

         (b) Similar to BTi, Neuromag Oy, is engaged in research, development
         and manufacturing of magnetic source imaging systems. Neuromag Oy is
         located in Helsinki, Finland. BTi intends to continue the operations
         of Neuromag Oy as a subsidiary of BTi.

         The description of the transaction set forth above is qualified in its
         entirety by reference to the Share Purchase Agreement filed with this
         Current Report and the Press Release issued by BTi dated December 23,
         1999, copies of which are attached to this Current Report as Exhibits
         2.1 and 99.1, respectively.

ITEM 7.  FINANCIAL STATEMENTS AND EXHIBITS.

         (a)      FINANCIAL STATEMENTS OF BUSINESS ACQUIRED.

         The Financial Information of Neuromag Oy required to be filed pursuant
         to Item 7(a) of Form 8-K was not available at the time of filing of

         Persons on the part of Purchaser or the Company (including without

         change in ownership) is required for the lawful and valid execution,

6.       INDEMNITY

         6.1      Indemnity of Seller

         If Seller is in breach of this Agreement, the Purchase Price shall, as
         the sole and exclusive remedy, be reduced by an amount corresponding to
         the deficiency or cost or direct loss actually incurred by the
         Purchaser (subject to Section 6.2) as a direct result of such breach.
         Such reduction may not, however, in any event exceed ten percent (10%)
         of the Purchase Price, which constitutes Seller's maximum liability
         under this Agreement or otherwise on whatever ground.

<PAGE>


         6.2      Limitation of Liability

         Seller's liability under this Agreement (including under Section 6.1
         above) is limited as follows:

         (a)      For the purposes of this Agreement, a liability, which is
                  contingent, shall not constitute a deficiency, cost or loss,
                  unless and until such contingent liability becomes an actual
                  liability and is due and payable. No Claim may be made if the
                  claim is based on facts or circumstances known to Purchaser or
                  its advisors prior to Closing.

         (b)      Purchaser shall not be entitled to make any Claim to the
                  extent that a provision or allowance for the matter of the
                  deficiency, cost or loss (whether as a specific reserve or as
                  a general reserve) has been made in the Financial Statements,
                  or the same is otherwise accounted for or reflected in the
                  Financial Statements.

         (c)      No liability shall arise in respect of any breach of this
                  Agreement or otherwise:

                  (i)     if and to the extent that any Claim occurs as a result
                          of any legislation not in force at the date hereof, or
                          which takes effect retrospectively, or occurs as a
                          result of any increase in the rate of tax in force at
                          the date hereof or any change in the practice of the
                          relevant tax authorities;

                  (ii)    if such liability would not have arisen but for an
                          act, omission or transaction carried out by Purchaser,
                          or persons deriving title from Purchaser after
                          Closing.

         (d)      In the event it is found that there is a breach of this
                  Agreement for which Seller is liable, Purchaser shall be
                  entitled, by way of remedy, to a reduction of the Purchase
                  Price as set out in Section 6.1. This remedy shall be



                                       19
<PAGE>


                  exclusive, and it is specifically agreed that no remedy
                  whatsoever under the Finnish Sale of Goods Act (355/1987),
                  including (but not limited to) the right to rescind this
                  Agreement, shall be available to Purchaser.

         (e)      No reduction of the Purchase Price shall be made due to a
                  breach of this Agreement, unless the total amount of the
                  Claims, which Purchaser may make under this Agreement, in the
                  aggregate amounts to or exceeds One Hundred Thousand Dollars
                  (U.S. $100,000), in which case the reduction shall be made for
                  the full amount of the claim. No individual claim which is
                  less than Ten Thousand Dollars (U.S. $10,000) shall be taken
                  into account.

         (f)      No claim shall be brought unless notice in writing of any such
                  claim, accompanied by all relevant particulars thereof
                  specifying the nature of the breach and the amount claimed in
                  respect thereof, has been given to Seller within thirty (30)
                  days from the date Purchaser became aware of the circumstances
                  giving rise to a Claim, and in any event not later than twelve
                  (12) months from the Closing Date.

         (g)      No liability shall arise from any breach of this Agreement in
                  respect to any deficiency, cost or loss which is recoverable
                  under a policy of insurance in force on the Closing Date, or
                  which would have been recoverable had the insurance protection
                  level, which existed on August 11, 1999, been continued.

         (h)      Purchaser shall take all reasonable steps to mitigate losses
                  and Seller shall not be liable for any claim to the extent
                  Purchaser could reasonably have mitigated any cost or loss
                  resulting from a breach of this Agreement.

         (i)      When it is determined that Purchaser shall be entitled to
                  payment, subject to the limitations in this SECTION 6, PAYMENT
                  SHALL BE made directly from Seller, in immediately available
                  funds to the bank account(s) identified by Purchaser, within
                  10 days of final determination.

         6.3      Third Party Claims and Recovery

         In case Purchaser becomes aware of any Third Party Claim, which could
         lead to a breach of this Agreement, Purchaser shall, in order to
         maintain the right to bring a Claim against Seller:

         (a)      as soon as reasonably practicable, but in no event later than
                  thirty (30) days after the date Purchaser became aware of any
                  circumstance giving rise to a Third Party Claim, give notice
                  thereof to Seller;

         (b)      not make any admission of liability, agreement or compromise
                  with any person, body or authority in relation thereto,
                  without obtaining the prior consent of Seller;

         (c)      in any action resist, defend, appeal and compromise such claim
                  in the best interest of Seller;

         (d)      give Seller, or Seller's duly authorized representatives,
                  reasonable access to the personnel of Purchaser and to any
                  relevant premises, accounts, documents and records within
                  their respective power, to enable Seller, or Seller's duly
                  authorized representatives, to examine such claim, premises,
                  accounts, documents and records and to take copies or
                  photocopies thereof.

         In case a Third Party Claim would arise that could lead to a breach of
         this Agreement, any negotiation, dispute or litigation relating thereto
         with any third party shall be handled by Seller.

         If Seller has made any payment to Purchaser as a settlement of any
         claim (the "Settlement Payment") and Purchaser has the right to recover
         from any third party any amount payable as a result of facts or
         circumstances forming the basis of such claim, then Purchaser shall,
         upon request of Seller, either assign that right to Seller or, if
         Seller so directs, Purchaser shall at the direction and cost of Seller
         pursue the



                                       21
<PAGE>


         said recovery and account to Seller for any monies or property
         recovered. In either case, that portion of any amount recovered from
         the third party which is in excess of the Settlement Payment, after
         deduction of Seller's reasonable costs in pursuing said recovery, shall
         be the property of Purchaser.

         Notwithstanding any of the foregoing, Seller shall have no obligation
         to satisfy any claim in respect of any Third Party Claim before the
         matter is subject to a final non-appealable decision.

         6.4      Indemnity of Purchaser

         Purchaser shall as from the Closing Date indemnify, defend and hold
         Seller harmless against any and all losses, damages, costs and expenses
         (including reasonable attorneys' fees) actually suffered or incurred by
         Seller arising out of or resulting from any breach by Purchaser of this
         Agreement or from events or circumstances for which Seller does not
         bear any responsibility as agreed hereunder.

through an independent distributor) sold by BTI or Neuromag during the
Royalty Period, of which royalties Instru shall always receive thirty-five
point nine (35.9) and SITRA sixty-four point one (64.1) per cent from
Marconi. Where Products are sold through an independent distributor, BTI
hereby irrevocably agrees to pay Marconi royalties in the amount of *** of
the Distributor Sale Price of all Products sold by BTI or Neuromag during the
Royalty Period. A Product shall be deemed sold on the date that the Product
is shipped by BTI or Neuromag, as the case may be. The purchase price of
shielded rooms sold by BTI or Neuromag shall be a deduction from the End-User
Sales Price or the Distributor Sale Price, as the case may be. In case
Products are subject to revenue sharing arrangements, e.g. invoiced on a fee
per scan basis, or otherwise leased by BTI, BTI shall pay royalties on the
staggered payments as they are made. It such transaction occurs during the
term of this Agreement, the obligation of BTI to pay royalties for such
transaction shall continue notwithstanding the end of the term of this
Agreement.

2.2      Notwithstanding Section 2.1:

         a) BTI's minimum royalty obligation under this Agreement shall be the

3.       ROYALTY PAYMENT

3.1 Within sixty (60) days from each anniversary of the Closing Date, BTI shall
render a written report to Marconi (each a "Royalty Report") stating the
quantity and End User Sale Price or Distributor Sale Price (as the case may be)
of all Products sold, leased or otherwise disposed of during the one (1) year
period ending on the anniversary of the Closing Date, together with a
calculation of the amount shown therein to be due (the "Annual Royalty"). For
the year ending on:

         a) the first anniversary of the Closing Date, the report shall be
accompanied by remittance in full of the Annual Royalty.

         b) the second anniversary of the Closing Date, the report shall be
accompanied by remittance in full of the Annual Royalty plus the Initial
Difference Amount. For the avoidance of doubt, example calculations of the
amount due under this Section 3.1(b) are set forth in SCHEDULE 3.1(B) attached
hereto and incorporated by reference herein.

         c) each of the third, fourth, fifth, sixth, seventh, and eighth
anniversaries of the Closing Date, the report shall be accompanied by remittance
in full of the Annual Royalty plus the Annual Difference Amount.

3.2. Upon payment pursuant to Section 3.1 above of aggregate amounts:

         a) equal to the Minimum Royalty, BTI shall not be required to pay any
additional Annual Difference Amount.

         b) equal to the Maximum Royalty, BTI shall not be required to pay any
additional Annual Royalty or Annual Difference Amount.

3.3 Upon payment pursuant to Section 3.1 of aggregate amounts equal to or
greater than the Minimum Royalty, the aggregate of the Initial Difference Amount
and the Annual Difference Amounts already paid pursuant to Section 3.1 shall be
a credit against future Annual Royalties.


                                       43
<PAGE>


3.4 Any payment under this Agreement shall be considered made when BTI has
effected such payment, to a bank account assigned by Marconi or according to
such other instructions as may be provided from time to time in writing by
Marconi, free from any taxes, levies, bank fees and charges and the like. Any
payment under this Agreement not made when due shall be subject to interest
at the lesser of (i) *** per year; or (ii) the maximum rate allowed by law.

3.5 Marconi acknowledges that it is required to transfer the Royalties received
by Marconi from BTI hereunder to Instru and SITRA (collectively, the "Previous
Shareholders") pursuant to an arrangement between Marconi and the Previous
Shareholders (the "Previous Shareholders Royalty Agreement"). Marconi will
indemnify, defend, and hold BTI harmless against any claim asserted by the
Previous Shareholders to the extent that such claim alleges or is based upon
Marconi's failure to transfer any Royalties received by Marconi from BTI to the
Previous Shareholders pursuant to the terms of the Previous Shareholders'
Royalty Agreement.

4.       SECURITY

         As security for its obligations under this Agreement, BTI shall prior
to the execution of this Agreement provide Marconi with a third party guarantee
(the "Guarantee"), which shall be satisfactory to Marconi, in an amount equal to
the Initial Minimum Royalty Portion until May 22, 2002, whereupon the Guarantee
shall continue to be in force in an amount equal to the Annual Minimum Royalty
Portion until May 22, 2008, of which Guarantee a copy is attached to this
Agreement as SCHEDULE 4. In the event that Marconi has to draw down on all or a
part of the Guarantee, BTI shall immediately and in any case within thirty (30)
days upon such draw down replenish the Guarantee to the above required amount or
obtain an alternate guarantee of form substantially similar to the Guarantee in
the above required amount. The Guarantee shall include a provision whereby
Marconi has the right to transfer its rights under the guarantee to Instru
and/or SITRA. BTI's obligation to provide the foregoing Guarantee shall
terminate upon payment pursuant to Section 3.1 of all the Royalties to be paid
under this Agreement.

         4.INDEMNIFICATION.

                  4.1 MARCONI INDEMNIFICATION. Marconi shall indemnify,
defend and hold BTi and its directors, officers, employees, agents and
representatives (collectively, the "BTi Parties") harmless from and against
any and all costs, losses, claims, liabilities, fines, penalties, damages and
expenses, court costs, reasonable fees and disbursements of counsel,
consultants and expert witnesses (collectively, "Damages") incurred or
suffered by the BTi Parties as a consequence of any other liability or
obligation of Marconi not specifically assumed by BTi pursuant to this
Agreement or any Ancillary Agreement. For the purpose of this clause,
Neuromag is expressly excluded from the BTi Parties except as stipulated in
the Old Agreement (without giving effect to loss of rights arising out of the
termination of the Old Agreement).

                  4.2 BTI INDEMNIFICATION. BTi shall indemnify, defend and hold
Marconi and its directors, officers, employees, agents and representatives
(collectively, the "Marconi Parties") harmless from and against any and all
costs, losses, claims, liabilities, fines, penalties, damages and expenses,
court costs, reasonable fees and disbursements of counsel, consultants and
expert witnesses (collectively, ("Damages") incurred or suffered by the Marconi
Parties as a consequence of any failure to perform duly and punctually any
covenant, agreement, obligation, liability or undertaking assumed by BTi
pursuant to this Agreement or any of the Ancillary Agreements.

                  4.3 NEUROMAG INDEMNIFICATION. Neuromag shall indemnify, defend
and hold Marconi and its directors, officers, employees, agents and
representatives (collectively, the "Marconi Parties") harmless from and against
any and all costs, losses, claims, liabilities, fines, penalties, damages and
expenses, court costs, reasonable fees and disbursements of counsel, consultants
and expert witnesses (collectively, "Damages") incurred or suffered by the
Marconi Parties as a consequence of any failure

<PAGE>


to perform duly and punctually any covenant, agreement, obligation, liability or
undertaking of Neuromag whether arising under this Agreement, any Ancillary
Agreement,or as stipulated in the Old Agreement(without giving effect to loss of
rights arising out of the termination of the Old Agreement).

                  4.4 NOTICE AND OPPORTUNITY TO DEFEND. The indemnified party,
as the case may be, shall give the indemnifying party notice (either oral or
written) of any claim that could give rise to the indemnified party's right to
indemnification under Sections 4.1, 4.2 or 4.3 as soon as practicable after the
indemnified party's receipt of such notice. Notwithstanding any other term of
this Agreement, the indemnified party's failure to give notice in the manner
provided in this Section 4.4 shall not relieve the indemnifying party of its
indemnification obligations under this Agreement. The indemnifying party shall
have the right, at its option, to compromise or defend, at its own expense and
by its own counsel, any such matter involving the asserted liability of the
party seeking such indemnification. If the indemnifying party shall undertake to
compromise or defend any such asserted liability, the indemnifying party shall
promptly (and in any event not less than ten (10) days after receipt of the
indemnified party's original notice) notify the indemnified party in writing of
the indemnifying party's intention to do so. If the indemnifying party elects
not to compromise or defend the asserted liability, fails to notify indemnified
party's election to compromise or defend as herein provided, fails to admit its
obligation to indemnify under this Agreement with respect to the claim, or, if
in indemnified party's opinion, the claim could result in the indemnified
party's becoming subject to injunctive relief or relief other than the payment
of money damages that could materially adversely affect the ongoing business of
the indemnified party in any manner, the indemnified party shall have the right,
at its option, to pay, compromise or defend such asserted liability by its own
counsel and its reasonable costs and expenses shall be included as part of the
indemnifying party's indemnification obligation under this Agreement. If the
indemnifying party chooses to defend any claim, then (A) the indemnified party
may participate in the defense of any claim at its own expense and (B) the
indemnified party shall make available to the indemnifying party any books,
records or other documents within its control that are necessary or appropriate
for such defense. Notwithstanding anything to the contrary in this Section 4.4,
the indemnifying party shall (A) keep the indemnified party informed on a
reasonable and timely basis as to the status of the defense of such claim and
(B) conduct the defense of such claim in a prudent manner. Notwithstanding
anything to the contrary in this Section 4.4, the indemnifying party shall not
cease to defend, settle or otherwise dispose of any claim without the
indemnified party's prior written consent of the indemnified party (which
consent shall not be unreasonably withheld).

                  4.5 SURVIVAL OF INDEMNIFICATION OBLIGATION. Notwithstanding
any other provision of this Agreement, Marconi's, BTi's, and Neuromag's
indemnification obligations under Article 4 shall survive any termination of
this Agreement.

         5. LIMITATION ON DAMAGES. No party hereto shall be liable or
responsible for any incidental, consequential, punitive or special damages
resulting from or in any way relating to the performance of any breach under
this Agreement.

under any circumstances for any failure or delay in performance hereunder which
is caused by an act of God or any other cause beyond the reasonable control of
either party or any cause without either party's fault or negligence. If either
party is prevented from or delayed in performing any of its obligations under
this Agreement by force majeure, then that party shall give notice thereof and
shall thereupon be excused from the performance of such obligation for as long
as the circumstances of force majeure continue.

BIOMAGNETIC TECHNOLOGIES INC. ANNOUNCES ITS COMBINATION WITH NEUROMAG OY; TO
BE KNOWN AS 4-D NEUROIMAGING

San Diego, California, December 23, 1999 -- Biomagnetic Technologies, Inc
("BTi"), (OCTBB: BMTI) is extremely pleased to announce today its combination
with Neuromag Oy.

This combination of the two world leaders in the field of Magnetic Source
Imaging (MSI) will be known as 4-D NeuroImaging.  The names BTi and Neuromag
are synonymous with the great strides in MSI instrumentation that have
occurred over the last 10 years.  Through collaboration with their extensive
customer bases, the companies have contributed significantly to the recent
emergence of MSI as a powerful clinical tool.  While individually successful,
both companies realized that the full potential of MSI could be achieved more
rapidly by the combination of their extensive expertise in hardware and
software development for both research and clinical applications. By drawing
upon the best elements of the technology and applications experience of each
partner, 4-D NeuroImaging offers an exceptional, and heretofore unavailable,
resource for present and future MSI customers.

4-D NeuroImaging will continue the tradition of service and support that have
been hallmarks of the founding companies.  Both the VectorView and the Magnes
product lines will continue to be produced and fully supported, thereby
providing the broadest set of choices for our present and future customers.
4-D NeuroImaging, with company offices in San Diego, Helsinki, Finland, and
Aachen, Germany, and strong distribution in Japan and the rest of the world,
will provide an extensive global presence.

As was the case of the founding companies, 4-D NeuroImaging is committed to
the promotion of cooperation amongst the members of its far flung and diverse
customer base to develop clinical applications, to expand the frontiers of
brain research, and to make MSI the tool of choice for functional imaging of
the human brain.

The combination of the companies was accomplished when BTi purchased 100% of
the capital stock of Neuromag Oy using debt financing as part of its ongoing
financial strategy.

"The formation of 4-D NeuroImaging will significantly enhance the combined
value of both companies, and provide the necessary critical mass in
technology, applications, distribution and customer base to accelerate the
clinical acceptance of MSI as a tool for diagnosis and treatment of
neurological and neuropsychiatric disease," commented D. Scott Buchanan,
President and CEO of BTi.

"I am very pleased to see these two principals in the field of MSI come
together in a manner that will enhance each company's capabilities.
Nueromag's success in the Asian and Research market combined with BTi's
success in the Clinical market, will allow 4-D NeuroImaging to effectively
serve all market segments worldwide,"  said Dr. Enrique Maso, Chairman of
BTi, now 4-D NeuroImaging.

Antti Ahonen, General Manager of Neuromag commented that "The time is right to
bring together these two pioneers of biomagnetism.  4-D NeuroImaging will
allow both companies to continue to exercise their strengths and to combine
them to accelerate the commercial and clinical acceptance of MSI."

The new company starts with a backlog of six systems and is well positioned
to capture a growing market in MSI from a position of strength.

4-D NeuroImaging, headquartered in San Diego, CA, is dedicated to the
development of Magnetic Source Imaging systems that measure magnetic fields
in the human body and assist in the diagnosis of a potentially broad range of
medical disorders.  Its main products, the Magnes and VectorView systems,
provide the most complete line of equipment for examination of brain
function.  More than 200 insurance companies and healthcare providers have
approved reimbursement for certain MSI procedures performed with these
systems.
