The notary explained the prohibition against involvement pursuant to the
Notarial Code of the City of Basel (EG/ZGB ? 233 Para. 1 No. 4) and pursuant
to the German law on drawing up documents (? 3 Para. 1 No. 7).  The question
as to whether the Notary or the office partner of the Notary or any other
persons affiliated with the Notary in the exercise of his profession or
working in the same offices is/are involved in the sense of these provisions
was denied both by the parties involved and by the Notary.

The person appearing, acting as stated above, declared as follows, with the
request that this be documented by the Notary:

                             Preliminary Remarks

1.    With a notarial document of the officiating Notary, Dr. Dieter
      Granicher, Basel (Switzerland) (Document Record 2000/60), Rofin
      acquired from MDKM all the shares held by MDKM in Carl Baasel
      Lasertechnik GmbH (referred to as the "document" hereinafter).  The
      document is known to the parties and they waive having it read aloud
      and attached as an appendix to this agreement.

2.    Pursuant to Art. 6.3 of the document, MDKM undertook to transfer to
      Rofin its rights and obligations resulting from the option agreement
      between Mr. Carl Baasel and MDKM (Document Record No. 3374/1999 of
      Notary Dr. Peter Anton, Munich) (referred to as the "option agreement"
      hereinafter), which is known to the parties, who waive having it read
      aloud and attached as an appendix to this agreement.  Rofin has
      undertaken to conclude such an agreement and to accept the transfer.

In execution of the aforementioned obligations, MDKM and Rofin agree as
follows:

                                      Section 1

1.1   MDKM hereby transfers to Rofin its rights and obligations resulting
      from the option agreement, thereby being released from all liability.

1.2   Rofin accepts the transfer.

1.3   The provisions of Article 6.3 Sentences 4 to 6 of the document continue
      to apply.  MDKM does not accept any warranty or guarantee with regard
      to the option agreement, over and above the guarantee provided in
      Article 6.3 Sentence 6 of the document.

                                      Section 2

2.1   The commerce taxes, fees (including notarial fees), public charges and
      costs that occur in connection with this agreement or its
      implementation will be paid by Rofin.

2.2   Each party will pay the taxes and costs it incurs for its own
      consultants.

                                                               [initials]

                                  Option Agreement

                                      between

                          Mannesmann Demag Krauss-Maffei AG
                            with domicile in Munich (MDKM)

                                        and

                        Carl Ferdinand Baasel, Starnberg (CFB)

I.    Preamble

The shareholders of the company Carl Baasel Lasertechnik GmbH [limited
liability corporation] - referred to as the company hereinafter - registered
in the Commercial Register of the Munich District Court under HRB 70075, with
domicile in Starnberg, with a fully paid-in capital stock of DM 4,000,000.00,
are CFB with two shares with a par value of a total of DM 399,600.00,
corresponding to 9.99% of the capital stock, Mr. Josef Settele with a share
of DM 120,000.00, corresponding to 3% of the capital stock, which share was
sold and ceded to MDKM by a notarial document, effective today (Document
Record No. .../99), and MDKM with two shares with a par value of a total of
DM 3,480,400.00, corresponding to 87.01% of the capital stock (referred to as
MDKM shares hereinafter).

MDKM intends to sell its interest in the company.  CFB might not wish to sell
his interest until a later point in time.  In order to grant an acquiring
party an assured legal position to acquisition of 100% of the shares of the
company and, on the other hand, to allow MDKM the necessary freedom to
conduct negotiations, the parties, with this agreement, grant one another
reciprocal put and call options with regard to the shares held by CFB, which
MDKM can transfer to an acquiring party.

This stated, the parties agree as follows:




















                                                                 [initials]

<PAGE>

                                  Section 1
                               Purchase Option

CFB hereby grants MDKM an irrevocable, unconditional option to acquire the
shares in the company held by CFB, in the amount of DM 380,000.00 and DM
19,600.00 (referred to as "option shares" hereinafter), by purchasing them.
MDKM can exercise the purchase option at any time, but no earlier than
1/1/03, with advance notice of one month by means of notarial declaration
issued to CFB.  When the acceptance declaration is received by CFB, a
purchase agreement at the terms stated in section 3 will come about.  The
option can only be exercised uniformly, with regard to all the option shares.

                                  Section 2
                               Selling Option

MDKM hereby grants CFB an irrevocable, unconditional option, which can be
exercised at any time, but no later than 12/31/07, to sell the option shares
to MDKM.  CFB can exercise the selling option with advance notice of one
month, by means of a notarial declaration issued to MDKM.  When the
acceptance declaration is received by MDKM or the party acquiring the MDKM
shares, to whom MDKM has transferred the rights and obligations resulting
from this agreement, pursuant to section 4.1, a purchase agreement at the
terms stated in section 3 will come about.  Section 1 Sentence 4 applies
analogously.

                                  Section 3
                             Purchase Agreement

3.1    CFB sells the option shares to MDKM, with all their rights and
       obligations, effective on the date this purchase agreement comes
       about, and cedes them to MDKM.

       The purchase price for the option shares is DM 12,287,000.00 (in
       words: twelve million two hundred eighty-seven thousand German marks),
       referred to as "base purchase price" hereinafter.


















                                                                [initials]

<PAGE>

3.2   If MDKM achieves a purchase price related to 100% of the shares of the
      company of more than DM 130,000,000.00 (one hundred thirty million
      German marks) in a sale of all shares of the company (with the transfer
      of rights and obligations resulting from this agreement counting as a
      share of the option shares, with regard to the option shares), before
      12/31/02 (deciding factor: date of the notarial agreement), the base
      price to be paid to CFB pursuant to 3.1 is increased by 80% of the
      additional purchase price that exceeds DM 130,000,000.00, calculated
      with reference to the option shares (9.99% of the capital stock)
      (increased price).  In this connection, any monetary or ancillary
      payments, equivalent to money, which are paid by the acquiring party,
      must be included as part of the purchase price, if they would be viewed
      as an additional purchase price or a substitute purchase price when
      considered from an objective economic point of view.  If the acquiring
      party settles monetary commerce accounts or redeems group or bank
      guaranties assumed on behalf of the company, this is not considered
      part of the purchase price.  If MDKM sells only part of the shares
      and/or the option shares of the company, Para. 3.2 applies analogously,
      with the provision that for purposes of the application of Para. 3.2 to
      the relationship between the parties, partial sales always count as
      proportional sales of the shares of MDKM and the option shares, in a
      ratio of 90.01 : 9.99, regardless of the actual conditions.

3.3   CFB warrants that the option shares are established with legal
      validity, fully paid in, and free of the rights of third parties,
      particularly that the option shares have not been placed under lien nor
      ceded as security or for any other reason to a third party, and that
      there are no other rights of third parties to acquisition of the option
      shares.  Any further warranty or liability, no matter for what legal
      reason it might exist, is precluded.

3.4   Cession of the option shares takes place with the postponing condition
      of payment of the full purchase price.  The purchase price owed becomes
      due within 30 days after this purchase agreement goes into effect.



















                                                                  [initials]

                                Section 4
                     Cession of the Legal Position

4.1   MDKM is entitled to transfer all the rights and obligations resulting
      from this agreement, with the effect of being released from all
      liability, to the party acquiring the MDKM shares, or to a third party
      named by such acquiring party.  This agreement will be referred to as
      "option cession agreement" hereinafter.  MDKM will inform CFB about the
      identity of the party acquiring the MDKM shares, in person, within 10
      days before notarization of the sale of the MDKM shares, and will
      request CFB to exercise his option right, as described below, within 8
      days after receipt of this information.

4.2   MDKM warrants that

      a)  At the request of CFB, which request must be declared to MDKM,
          before the option cession agreement is concluded, the party
          acquiring the MDKM shares, or a third party, at the request of the
          acquiring party, issues an unconditional guaranty of a major German
          bank for DM 12,287,000.00, for its own account, which is
          irrevocable until 4/1/03, and which is issued with waiver of the
          objections pursuant to section 770 and section 771 BGB [German
          Civil Code] as well as the right of deposit, and secures CFB's
          claims resulting from this agreement, or

      b)  if CFB has not issued a request pursuant to Number 4.2 a) before
          conclusion of the option cession agreement, the party acquiring
          the MDKM shares takes on the obligation to give CFB the guaranty
          indicated in Number 4.2 a), at his request,

      c)  where in either of the aforementioned cases, CFB can give the
          guaranty back at any time.

4.3   The documented costs of this guaranty will be paid by CFB up to a
      maximum amount of 0.50% p.a., until return of the guaranty.



















                                                                [initials]

                                 Section 5
                                Miscellaneous

5.1   MDKM takes on the obligation, with regard to CFB, to exercise its vote
      in the general shareholders' meeting of the company that decides about
      the allocation of the profit for 1999, to the effect that the highest
      possible distribution of the surplus for the year 1999 will be
      resolved.

5.2   The parties to the agreement are in accord that the provisions of this
      agreement concerning the option shares will always take precedence over
      the provisions of the bylaws of the company.  MDKM takes on the
      obligation, with regard to CFB, to work towards annulment of section 7
      Para. 5 and 6 of the bylaws and towards an agreement concerning a claim
      to full distribution for the shareholders, by giving its approval in
      this regard, at the next general shareholders' meeting of the company.

5.3   Upon request by MDKM or the party acquiring the MDKM shares, CFB will
      work towards a shareholders' resolution that provides that in future
      fiscal years (including the fiscal year in which the option is
      exercised, but not longer than for the fiscal year ending on 12/31/02),
      full distribution of the surplus for the year that is achieved in each
      instance will take place or, for the option shares, that a guaranteed
      dividend in the amount of 5.75% p.a. of the base purchase price (if the
      option is exercised early: on a prorated basis) will be paid by the
      company or the majority shareholder, independent of the actual balance
      sheet result for the year in each instance.  The acquiring party must
      exercise this option by 3/31/01, but not before the end of six months
      after acquisition of the MDKM shares.  If the acquiring party does not
      exercise this option, full distribution of the profit for the year in
      each instance is considered to have been agreed.

5.4   If payment of a guaranteed dividend is resolved, CFB can demand that
      the acquiring party provide security as described in Number 4.2 a) for
      the entire amount of the guaranteed dividends to be paid for the
      periods up to 1/1/03.  MDKM warrants that the acquiring party will
      provide such security.

                                  Section 6
                                    Costs

The costs of this document and its implementation will be paid by MDKM.
Unless otherwise agreed, each party pays its own costs as it incurs them.











                                                               [initials]

<PAGE>
                                 Section 7
                               Validity Clause

If a provision of this agreement is or becomes null, unenforceable, or
legally invalid, regardless of the reason, this does not affect the validity
of the other provisions.  The invalid, ineffective, or unenforceable
provision must be replaced by a new and enforceable provision that
corresponds to the economic intent of the parties when concluding the
agreement.  The same holds true if it turns out that there are gaps in the
agreement.

                                  Section 8
                               Confidentiality

The parties to the agreement undertake to treat the content of this agreement
as confidential until 6/30/00, but at most until sale of the MDKM shares
occurs, and not to inform uninvolved third parties of it, unless this is
necessary within the scope of the sales process ("need to know basis").




































                                                                 [initials]

                   [deleted by hand, corrected to 9]
                               Notes, Copies

The parties were instructed that a cession of shares if the option is
exercised must be reported to the company, pursuant to section 16 GmbHG [law
on limited liability companies].  The Notary furthermore pointed out the
obligation of the management to immediately file a new list of shareholders
with the Commercial Register.  This will be done by the parties after the
cession of shares goes into effect.

Subjugation to collection measures for the purchase price obligation is
waived.

There is no real estate included in the assets of the company.

The following parties receive a copy of this document:

a)    each party to the agreement,
b)    the company,
c)    the German Revenue Office as a notice pursuant to section 54 EStDVO
      [code for enforcement of income tax law].
