     certificate is attached as Schedule E.




EXHIBIT 10.12

13.4 The Borrowers will jointly and severally ensure that, based on the
     Financial Statements and per the date to which they relate, as any sum
     remains to be lent to or remains payable under this Agreement:

     (a)  the Stockholders' Equity will in the year 1999 not be less than
          US-Dollars 92 million;

     (b)  the Stockholders' Equity will in the year 2000 and 2001 not be less
          than US Dollars 100 million;

     (c)  the ratio of Stockholders Equity to Total Capitalization will be more
          than 1 to 2;

     (d)  the ratio of Income from Operations to Interest Expense will not in
          respect of any financial year of the FEI Group, or any 12 month period
          ending on the last day of a quarter, be less than 4 for the first and
          second quarter of 1999 and thereafter not less than 6.

     If FEI Group acquires assets for an amount exceeding 25% of its
     Stockholders' Equity according to its latest Financial Statements before
     such acquisition, the Borrowers may request the Lender to adjust the
     minimum ratios mentioned under 13.4 sub (d) to reflect such acquisition.

13.5 FEI will not dispose and will procure that none of its subsidiaries
     (including PEO) will, except with the consent of the Lender (disregarding
     disposals in the ordinary course of business and any sale, lease, transfer
     or other disposal of any of its revenues or its assets on an arm's length
     basis for fair market value and the payment of lawful dividends) sell,
     lease, transfer, lend (other than the lending of cash to any of its
     subsidiaries) or otherwise dispose of, by one or more transactions or
     series of transactions (whether related or not), the whole or any material
     part of its respective business, revenues or assets ("material" in this
     context means a sale, lease, transfer, loan or disposal of any part of its
     business, assets or revenues which, by itself (in the case of a single
     transaction) or which aggregated (in the case of a number of related
     transactions), is more than 10 percent of the revenues or assets of the FEI
     Group taken as a whole or, in any case, the disposal of which (alone or so
     aggregated) would have a material adverse effect on any Borrower's ability
     to perform or comply with its obligations under this Agreement).

13.6 FEI will ensure that there is no material change in the nature of the
     business of the FEI Group taken as a whole (whether by a single transaction
     or a number of related or unrelated transactions, whether at one time or
     over a period of time and whether by disposal, acquisition or otherwise)
     which has or could have a material adverse effect on any Borrower's ability
     to perform and comply with its obligations under this Agreement.




EXHIBIT 10.12

14.  EVENTS OF DEFAULT

The following are Events of Default:

(a)  Non-payment: The Borrowers do not pay in the manner provided in this
     Agreement (i) any principal payable under it when due, unless the Borrowers
     satisfy the Lender that non-payment is due solely to administrative error
     (whether by the Borrowers or a bank involved in transferring funds to the
     Lender) and payment is made within 5 Business Days after written notice of
     that non-payment has been given to it by the Lender or (ii) any other sum
     payable under it within 10 Business Days after written notice of that
     non-payment has been given to it by the Lender.

(b)  Breach of Representation or Warranty: Any representation or warranty by the
     Borrowers pursuant to Clause 10 is not complied with in any material
     respect or is or proves to have been incorrect, in any material respect,
     when made.

(c)  Breach of Other Obligation: The Borrowers do not perform or comply in any
     material respect with any one or more of their other obligations under this
     Agreement and, if that default is capable of remedy, it is not remedied
     within 30 days after written notice of that default has been given to it by
     the Lender.

(d)  Cross Default: Any other indebtedness of the Borrowers in respect of
     borrowed money and forming part of its Total Debt (i) is payable (whether
     automatically under the provisions of any agreement relating to that
     indebtedness or as a result of any declaration or the Eke made under any
     such agreement) before its normal maturity by reason of any actual default
     or event of default, however described, and is not paid on becoming so
     payable or within any applicable grace period unless it is being contested
     in good faith by appropriate means or (ii) is not paid by reason of the
     actual default of the Borrowers when due nor within any applicable grace
     period in any agreement relating to that indebtedness unless it is being
     contested in good faith by appropriate means, except in any such case where
     the Borrowers is prevented, directly or indirectly, by any government or
     other authority from fulfilling the relevant obligation. However, no Event
     of Default will occur under this Clause 14 (d) unless the amount of the
     indebtedness for borrowed money in respect of which any event mentioned in
     this Clause 14 (d) has occurred equals or exceeds US-Dollars 5 million or
     its equivalent in other currencies (as reasonably determined by the
     Lender).




EXHIBIT 10.12


(e)  INSOLVENCY: FEI or PEOI is (or is deemed by law or a court to be) insolvent
     (including a faillissement (within the meaning of the Netherlands'
     bankruptcy act) or unable to pay its debts or one of the Borrowers stops,
     suspends or threatens to stop or suspend payment of all or a material part
     of its indebtedness (including a surse'ance van betaling, within the
     meaning of the Netherlands' bankruptcy act), begins negotiations or takes
     any other step with a view to the deferral, rescheduling or other
     readjustment of all of its indebtedness (or of any material part which it
     will or might otherwise be unable to pay when due), proposes or makes a
     general assignment or an arrangement or composition with or for the benefit
     of the relevant creditors or a moratorium is agreed or declared in respect
     of or affecting all or a material part of the indebtedness of the
     Borrowers.

(f)  WINDING-UP: An order is made or an effective resolution is passed for the
     winding-up of one of the Borrowers.

(g)  ANALOGOUS EVENTS: Any event occurs which, under the law of any relevant
     jurisdiction, has an analogous or equivalent effect to any event mentioned
     in Clause 14 (e).

(h)  CHANGE OF CONTROL: The Lender has given written notice to FEI that it
     ceases to own directly or indirectly more than 50 per cent of the issued
     equity share capital of FEI. However, no Event of Default will occur under
     this clause 14 (h) unless 120 days have elapsed since the Lender ceased to
     own directly or indirectly more than 50 per cent of the issued equity share
     capital of FEI, or since the relevant written notice, whichever is latest.

(i)  CHANGE IN RELATIONSHIP BORROWERS: FEI ceases to own directly or indirectly
     100 per cent of the issued equity share capital of PEOI, unless such
     reduction is approved beforehand in writing by the Lender.

If at any time and for any reason (and whether within or beyond the control of
any party to this Agreement) any Event of Default has occurred then at any time
thereafter, the Lender shall by written notice to the Borrowers declare all
Outstanding Amounts, all unpaid accrued interest or fees and any other sum then
payable under this Agreement to be immediately due and payable, whereupon they
shall become so due and payable, unless the event which constitutes the Event of
Default is remedied before the Lender has sent the aforementioned notice and the
Lender is informed of such remedy by the Borrowers in writing before the Lender
sent such notice.




EXHIBIT 10.12

However, if the Event of Default as referred to under Clause 14 (e) or 14 (g) is
capable of being cured, the Outstanding Amounts, all unpaid accrued interest or
fees and any other sum then payable under this Agreement, shall become due and
payable 5 days after the notice to declare all such amounts due and payable has
been sent by the Lender, unless the Lender explicitly mentions a different
period in such notice, and unless FEI Group did not meet the ratios mentioned in
Clause 13.4, based on latest monthly management report as FEI submits to the
Lender each month, in which case all amounts outstanding as referred to win
become due and payable immediately. If an Event of Default as referred to under
Clause 14 (e) or 14 (g) has
occurred, no Revolving Advances or draw downs form the Current Account will be
possible till such Event of Default is cured, unless approved by the Lender
beforehand.

At any time after such occurrence the Lender may, by notice in writing to the
Borrowers, declare that the Facility is cancelled and that all amounts
outstanding thereunder, if any, are immediately due and payable, together with
interest thereon and any other costs, charges and expenses. Such declaration
shall be effective forthwith.

The Borrowers jointly and severally under-take to indemnify the Lender against
any reasonable direct loss or expenses which any of them may sustain or incur as
a consequence of the occurrence of any Event of Default hereunder.

15.  CANCELLATION BY BORROWERS

15.1 NOTICE OF CANCELLATION

     FEI may declare on behalf of the Borrowers in writing that the Facility is
     cancelled in full or in part. If the Facility is cancelled in part, such

     will be effective on the date mentioned in the notice ("Cancellation
     date"). The Cancellation Date should be at least five (5) Business Days
     after receipt by the Lender of such notice.

15.2 PARTIAL CANCELLATION

     A partial cancellation will only become effective if on the Cancellation
     Date the Outstanding Amounts are less than the proposed amended Maximum
     Amount.

15.3 CANCELLATION IS IRREVOCABLE

     Any cancellation in accordance with this article 15 will be irrevocable.
     Any reduction of the Maximum Amount made in accordance with this Clause 15,

remedies herein provided are cumulative and not exclusive of any rights or
remedies provided by law.
