Dear Mr. Englmeier,

We are pleased to confirm to you that we will make a business line of credit
available to your company in an amount of

                                DM 5,000,000.--
                    (in words: Deutsche Mark five million).

Presently, until further notice, we will charge 6% p.a. for utilisation of this
line of credit.

Within the scope of this line of credit, as in the past, we are gladly prepared
to arrange for special financing, to acquire bills of exchange which fulfil the
requirements of the European Central Bank (ECB), to open documentary credits as
well as to conclude forward exchange deals.  Upon demand, we will co-ordinate
the respective terms with you.

To the account of this line of credit, pursuant to your loan application of 9
November 1998, we have taken over the commitment for the business loan amounting
to US$ 250,000. -- of Temic-RF Technologies (Phils.) Inc. at Deutsche Bank
Philippines, Manila Branch. Additionally, also to the account of the line of
credit, pursuant to your loan application of 9 March 1999, we have made a
business loan presently in an amount of DM 500,000. -- available to Toplan GmbH.
<PAGE>

You can use a portion of the line of credit in an amount of up to DM 2,500,000.
-- in order to refinance investment costs by way of loans with a maximum term of
up to 47 months.

We are limiting our commitment for the time being to 31 December 1999.  We will
contact you promptly prior to expiration of this time limit regarding the
further handling of the line of credit.

In connection with our willingness to provide finance, we still assume that you
will not put other banks in a better position regarding collateral for business
lines of credit and/or we will be given equal treatment in the event of a
possible provision of collateral.

We request that you keep us informed on the further economic development of your
company as well as subsidiaries in Manila by submission of quarterly business
analyses.

Our General Terms and Conditions are applicable.

As an indication of your agreement with this loan commitment, we request you
furnish the enclosed copy of this letter with a legally binding signature and
return this copy to us.

Sincerely yours,

Deutsche Bank AG
