    Article 5: Operations of the Bank Pool

    The interbank agreement signed on this date shall govern the relations among
    the banks with respect to this credit line.

    The Banks have designated CBC-Banque as Pool Coordinator.

    Article 6: Purpose

    The credit line, in its current forms, is intended to cover the Borrower's
    financial needs arising from the execution of its corporate purpose.

    Article 7: Accounts

    This credit line operates in one or more accounts (current or non-current)
    with each of the Banks. These accounts are only the elements of the sole and
    indivisible "credit account" which the Borrower has with each Bank.
    Therefore, each Bank may make transfers from one element of the "credit
    account" to another on its books, merge the accounts and offset the debit
    balances in some accounts with the credit balances of other accounts. When
    the transfer requires conversion of foreign currencies, the conversion rate
    shall be determined by the Banks.

    These accounts are governed at each of the Banks by the Bank's general
    conditions governing this type of account, with which the Borrower hereby
    expressly stipulates that it is familiar.

    All sums due may be recorded in an account as of the due date.

    Article 8: Forms of use

    The credit line may be used in all forms and under all conditions stipulated
    to or to be stipulated to by the parties, without resulting in novation.
    Until otherwise established, the credit line may be used in the forms and
    under the conditions defined hereinafter:

    A. EUR 26,800,000.00 in the form of bank guarantees issued with pledged
    deposits and EUR 10,000,000.00 in the form of bank guarantees without
    pledged deposits.

    The EUR 10,000,000.00 line shall be used only after the limit on the EUR
    26,800,000.00 line of credit has been reached.

    The issue of bank guarantees and all terms thereof, as well as any
    extensions of such guarantees, shall be subject, on a case by case basis, to
    the prior agreement of the Banks, without prejudice to the limits set by
    each Bank based on the current and future commitments of the Borrower
    resulting from agreements other than this agreement. Their use in the form
    of bank guarantees shall be recorded in the books of the Pool Coordinator.

    B. EUR 3,600,000 in the form of advances on current accounts and/or straight
    loans and/or letters of credit and EUR 9,000,000 in the form of an advance
    intended for the payment of installments of estimated corporate taxes.
    In addition to being governed by this agreement, these credit lines shall be
    governed by specific agreements to be established by each of the banks
    concerned within the Bank Pool. Their use shall be recorded in the books of
    the Lending Banks.

    The parties reserve the right to agree on new forms of use.

    In the event of termination pursuant to Article 17 (immediate payment), the
    credit account with each of the Banks shall be closed on the effective date
    of the termination.

    The existence and the amount of the claim of each of the Banks, as well as
    the position of the Borrower's "credit account" with each Bank, are verified
    by the account statement or by any other

                                                                               4

    accounting document prepared by the Banks; said documents shall constitute
    sufficient proof, without requiring presentation of any other instrument,
    whether recorded by notary or not, to be presented.

    Article 9: Compliance with legal and regulatory provisions

    The Borrower undertakes to comply with the regulations of the competent
    monetary authorities, in particular the Institut Belgo-Luxembourgeois du
    Change (IBLC) and to provide the Banks with any document or proof required
    by said authorities.

    The Borrower shall ensure, at any time, that it is performing its activities
    in strict compliance with the current and future regulations governing the
    import, export and transit of arms, munitions, military materiel and related
    technologies.

    Article 10: Terms and conditions of the lines that may be used in the form
    of bank guarantees

    a) Terms and conditions


       The Banks shall establish, to the order and on behalf of the Borrower,
       guarantees to return advances and performance guarantees, in EURO or in
       currencies, under the Borrower's entire and exclusive responsibility. The
       issuance of these guarantees shall be governed by the General Conditions
       governing the issuance of guarantees.

       Any request for the issuance of bank guarantees shall be subject to the
       prior written approval of the Banks.

    b) Chronology

       The Borrower undertakes to comply with the following chronology, contract
       by contract:

       -  receipt by the Pool Coordinator of the written request to issue a
          guarantee;
       -  request for approval from the Banks;
       -  receipt by the Banks of export credit letters;
       -  receipt by the Banks of a copy of the specific OND policy, possibly a
          definitive  undertaking subject to the condition
          precedent that export licenses are obtained;
       -  receipt of export licenses;
       -  issue of the guarantees;
       -  receipt and freezing of the pledge advances in accordance with the
          terms and conditions  stipulated in Articles 8 and 18A.

    The banks agree that the performance guarantees shall be issued before
    export licenses are obtained.

    This chronology may be modified with the prior written consent of the Banks.

                                                                               5

<PAGE>

    c) Commission and fees

       The issuance of guarantees shall result in the payment of a commission of
       1.25% per year, payable quarterly in advance, and every quarter started
       requiring full payment. It shall be calculated on the amount guaranteed
       at the beginning of the quarter and shall be due until the full and
       definitive discharge of the Banks' commitments.

       Moreover, the Borrower shall be responsible for commissions claimed by
       the Banks' correspondents, the final issuers of the guarantees.

       All other fees (telex, port, etc.) and costs incurred by the Banks in
       issuing the guarantees shall also be paid by the Borrower. The Borrower
       shall also be responsible for fees claims by the Banks' correspondents.

    Article 11: Terms and conditions for computing interest and commissions

    The debt interest and commissions shall be calculated on the basis of the
    actual number of days elapsed and a debt rate established on the basis of a
    commercial 360-day year (365 days for the pound sterling), except where
    otherwise stipulated herein.

    Article 12: Commissions on bank guarantees

    For each guarantee that the Banks agree to issue, two commissions of 1%
    shall be recorded.

    The first commission is due upon issuance by the Banks and shall be payable
    in one payment no later than the receipt of the first installment payment.

    The second commission is due on a prorated basis as the Borrower's receipts
    for its deliveries are received. However, for simplification purposes and
    until otherwise established, this second commission shall be deducted when
    the receipts for the last delivery of each contract are received.

    The Bank that has issued the guarantee on behalf of the Banks in the Bank
    Pool which have agreed to participate shall collect the Bank Pool's
    commissions from the Borrower, which so agrees, and shall repay to each of
    the other participating Banks the percentage to which it is entitled.

    Article 13: Charging the sums due to the "credit account" of each Bank

    The amount due on the Banks' claim results from the debit balance of the
    "credit account" on the day of the statement. At any time, even after this
    statement, the accounts may be debited for the amount that the Borrower owes
    or will owe all the Banks under this credit line.

    Article 14: Payments / Fees

    a) The Borrower hereby declares that it waives the benefit of Articles 1253,
       1255, and 1256 of the Civil Code and, therefore, grants the Banks the
       right to charge payments received, from any source, against the portion
       of the debt which the Banks intend to discharge.

                                                                               6

<PAGE>

    b) Any payment due on a date other than a bank business day must be made on
       the preceding bank business day.

       For the purpose of this agreement, a bank business day is a day when the
       Banks and the Clearing Chamber are open in Brussels (or, with respect to
       currencies, a day when the banks are operating simultaneously in
       Brussels, London and in the country of the currency).

    c) All costs, taxes, stamp taxes, recording fees, attorneys' fees,
       notification fees, renewal fees, discharge fees and, generally, all costs
       deemed necessary to create the securities or liquidate said securities or
       for the forced execution of the Borrower's obligations shall be paid by
       the Borrower.

       This is also true for all other sums due by the Borrower, for any reason,
       such as, for example, insurance premiums, if they have been advanced by
       the Banks.

    d) The Borrower shall be liable for the additional amount of EUR 12,500.00
       to CBC Banque for its participation in the costs to establish this
       agreement and the related agreements; this sum shall be payable at the
       time this agreement is signed.

    Article 15: Commitments

    The Borrower makes the following commitments as of the date of this
    agreement and until the payment in full of all sums due to the Banks
    hereunder:

    a) The Borrower shall allow persons delegated by the Banks to review on site
       the originals of the contracts that are the origin of the guarantees
       issued or to be issued, referred to hereinafter as the "export

    b) The Borrower shall act to ensure the receipt of all authorizations and
       approvals, the filing of all declarations, and the performance of all
       formalities that may be required with respect to Borrower after the date
       of this agreement in order to ensure its complete performance under this
       agreement.

    c) Upon receipt, the Borrower shall provide to the Banks the export licenses
       for the export contracts. It shall do the same with respect to license
       renewals.

    d) It shall provide the Banks, as soon as they are issued, with the OND
       policies described in Article 18 A 3 hereinafter; moreover, any review by
       the Banks of an export contract for which it is seeking financing shall
       be subject to the production of an OND commitment for said contract.

    e) Borrower shall ensure the legality of the transactions financed by this
       credit line with respect to Belgian, international or foreign
       legislation.

    f) Within 15 days after publication, the Borrower and its parent company

       within 30 days after they are established; the Borrower shall also
       present quarterly a statement of the progress of the export contracts and
       the latest provisional statement of the results for the year in progress.

                                                                               7

       information made by the Banks which could affect the execution of this
       agreement.

       It shall also allow the Banks to exercise any and all means of monitoring
       and control, at their expense (except in the event Borrowers fails in the
       obligations defined in the first paragraph of this point "h", in which
       case, the fees shall be paid by the Borrower).

    i) The Borrower shall inform the Banks of any circumstance and any act as
       defined in Article 17 (immediate payment) hereinafter, including all
       documents related to bylaw changes.

    j) As of this date, the Borrower shall not secure any loan, debt, guaranty
       or any commitment that constitutes a debt, by mortgage, lien, pledge,

       or undertaking to create a security interest of this type on all or part
       of its current and future assets, without the prior written agreement of
       the Banks. In such cases, the Banks shall have the right to demand that
       the Borrower provide the Banks with the same securities to guarantee this
       credit line, in the same proportion and with the same rank.

    k) The Borrower undertakes, as long as this credit line is utilized in its
       current forms, to consult the Banks at the time of any request for credit
       not described in this agreement. If the Banks' conditions are at least as
       favorable as those offered by the competition, the Borrower undertakes to
       give the Banks priority in extending it such additional credit.

    l) Each Bank shall receive from the Borrower a portion of the financial
       service in proportion to the percentage of its participation in this
       credit line.

    m) The Borrower undertakes, by signing this agreement, to maintain its
       equity capital (Items 10/15 - 20 - 21 - 50) at a minimum amount of EUR
       40,000,000.00 and its working capital (Items 10/15 + 16 + 17 - 20/28) at
       a minimum amount of EUR 30,000,000.00.

    n) The Borrower is prohibited from granting advances to companies that are
       part of the ALLIED RESEARCH CORPORATION Inc. group.

       request, the claims resulting from the delivery of letters of credit
       issued in its favor under the export contracts.

    Article 16: Merger

    In the event the Borrower is acquired by another company, in the event of
    merger by the formation of a new company, or in the event of consolidation
    of another company, the credit agreement shall continue with the new entity,
    except in a case governed by Article 17 (immediate payment) hereinafter.

    Article 17: Immediate payment

    The Banks have the option to suspend, close or terminate the credit line, in
    whole or in part, and to require the immediate repayment of all or part of
    their claim, without advance or formal notice:

                                                                               8
