         amount of the drawing. The Borrower's obligation to reimburse the
         Lender for any drawing under a Letter of Credit shall be absolute and
         unconditional, irrespective of any rights of set-off, counterclaim or
         defense to payment the Borrower may claim or have against the Lender,
         the beneficiary of the Letter of Credit or any other Person;

                                    (8)      Unless the Borrower makes
         reimbursement from another source on the day of the drawing under any
         Letter of Credit, the Borrower shall be deemed to have requested an
         Advance under the Revolving Loan in the amount of the drawing, and
         (i) Lender, at its option, may make such an Advance and apply the
         proceeds of the Advance to satisfy the Borrower's obligation to
         reimburse Lender for the amount drawn on the Letter of Credit; and
         (ii) the Advance shall be repayable, with interest, in accordance
         with the terms and conditions of the Revolving Note; and

                                    (9)      no Event of Default has occurred
         and remains uncured, and no event has occurred or circumstance exists
         which, with the passage of time or the giving of notice or both,
         would constitute an Event of Default.

                           e.       Use of Revolving Loan Proceeds.  The
                                    ------------------------------

issuance of letters of credit, to finance the performance of contracts,
including Government Contracts, and for general corporate purposes.

                                    --------------------

Agreement. These fees are in addition to interest payable under the Revolving
Note:

                                    (1)      an annual commitment fee of 15
         basis points (.15%), payable in equal quarterly installments over the
         term of the Revolving Loan based on the Maximum Revolving Commitment
         Amount, with the first payment payable on the Closing Date.

                                    (2)      a unused fee per annum of 20
         basis points (.20%)based on the unused portion of the Maximum
         Revolving Commitment Amount and payable quarterly, in arrears,
         commencing on the first day following the end of the first fiscal
         quarter of Borrower after the date of this Agreement. The unused fee
         shall be determined by applying a per-diem rate of interest based on
         the interest rate set forth herein, calculated on the basis of a 360
         day year, to the actual number of days that the portion of the
         Maximum Revolving Commitment Amount is unused.

                                    (3)      a fee for any draw on a letter of
         credit honored by Lender in an amount of 1.5% of the draw amount.

                                    (4)      The Lender reserves the right to
          perform field examinations at any time, in its sole discretion. Each

one of them, as individuals authorized to communicate with the Lender. The
Borrower authorizes the Lender to accept, rely upon, act upon and comply with,
any verbal or written instructions, requests, confirmations and orders of any
employee or agent so designated by the Borrower. The Borrower acknowledges that
the transmission between the Borrower and the Lender of any such instructions,
requests, confirmations and orders involves the possibility of errors,
omissions, mistakes and discrepancies and agrees to adopt such internal
measures and operational procedures as Borrower deems necessary to protect its
interests. The Borrower hereby assumes all risk of loss arising out of: (i) the
Lender's acceptance, reliance on, compliance with or observation of any such

                  --------------------------

financial accommodations now or hereafter made by the Lender for the benefit of
the Borrower, and (ii) for any other liability or

Amended and Restated Loan Agreement Draft #4                                 11

<PAGE>

obligation of Borrower to Lender whether now or hereafter existing, of every
kind and description, whether or not evidenced by notes or other instruments,
and whether or not such liability or obligations are direct or indirect, fixed
or contingent, liquidated or unliquidated, the Borrower hereby assigns, grants
and conveys to the Lender a security interest in the Collateral. In addition,
except as prohibited by law, Borrower grants to Lender a security interest in
all accounts of Borrower with Lender or any of Lender's Affiliates. The
Borrower further agrees that the Lender shall have in respect of the Collateral
all of the rights and remedies of a secured party under the Uniform Commercial
Code, other applicable law and this Agreement. The Borrower covenants and
agrees to execute and deliver such financing statements and other instruments
and filings or perform any and all acts as are necessary in the opinion of the
Lender to perfect, maintain and protect the security interest hereby granted.
The Borrower shall not dispose of the Collateral, or any part thereof, other
than in the ordinary course of its business or as otherwise may be permitted by
this Agreement.

         4.2      Certain Rights of the Lender. The Lender shall have the right,
                  ----------------------------
but not the obligation, (i) to pay any taxes or levies on the Collateral or any
costs to repair or to preserve the Collateral; and (ii) to cure any defaults by
Borrower on contracts by the Borrower intended to give rise to Accounts. Such
payments and the costs of curing such defaults shall constitute Advances under
the Revolving Note and shall be secured pursuant to this Agreement
notwithstanding that such Advances may cause the unpaid principal balance of
the Loan to exceed the Maximum Revolving Commitment Amount.

         4.3      Financing Statements. At the request of the Lender, Borrower
                  --------------------
will join with the Lender in executing financing statements, continuation
statements and other documents with respect to the Collateral pursuant to the
Uniform Commercial Code or otherwise, in form satisfactory to the Lender, and
Borrower will pay the cost of filing the same in all public offices wherever
the Lender deems filing to be necessary or desirable. Borrower agrees that a
carbon, photographic, photostatic or other reproduction of this Agreement or of
a financing statement is sufficient as a financing statement; provided,
however, that it shall not limit the obligations of Borrower as previously set
forth herein. Borrower grants the Lender the right, at the Lender's option, to
file any or all such financing statements, continuation statements and other
documents pursuant to the Uniform Commercial Code and otherwise, without
Borrower's signature, and irrevocably appoints the Lender as Borrower's
attorney-in-fact to execute any such statements and documents in Borrower's
name and to perform all other acts which the Lender deems appropriate to
perfect and to continue the security interests conferred by this Agreement.

         4.4      Records of Collateral; Information. Borrower at all times will
                  ----------------------------------
maintain accurate books and records covering the Collateral. Borrower
immediately will mark all books and records with an entry showing the absolute
assignment of and granting of a security interest in all Collateral to Lender,
and hereby grants the Lender the right to audit the books and records of
Borrower relating to Collateral at any time and from time to time. Borrower
shall (i) promptly furnish the Lender with any information with respect to
Collateral requested by Lender; (ii) allow the Lender or its representatives to
inspect the Collateral, at any time and wherever located, and to inspect and
copy, or furnish the Lender or its representatives with copies of all records
relating to the Collateral; (iii) furnish the Lender or its representatives such
information as the Lender may request to identify the Collateral, at the time
and in the form requested by

Amended and Restated Loan Agreement Draft #4                                 12

<PAGE>

Lender; and (iv) deliver upon request to Lender shipping and delivery receipts
evidencing the shipment of goods and invoices evidencing the receipt of the
Collateral and payment for the Collateral.

         4.5      No Release. No injury to the Collateral, loss or destruction
                  ----------
of the Collateral, failure to perfect or to continue the perfection of Lender's
security interest in the Collateral, or release of Lender's security interest
in the Collateral, or any part of it, shall relieve Borrower of any obligation
under this Agreement or under any of the other Loan Documents. Borrower
expressly waives all defenses based on suretyship or impairment of collateral,
and shall not be released or discharged of any obligation under the Loan
Documents, in whole or in part, by Lender's failure to protect or preserve the
Collateral. No Person, in deciding to enter into this Loan Agreement, has
relied on the execution of this Loan Agreement or the granting of a security
interest in Collateral by any other Person. Each Person comprised by the term
Borrower waives notice of any change in financial condition of any Person
liable for the Loans or any part thereof, and agrees that maturity of the Loans
or any part thereof may be accelerated, extended or renewed one or more times
by Lender in its discretion, without notice to the Person and without affecting
Lender's security interest in the Collateral. Lender shall not be required to
bring any action against any other Person or to resort to any other security or
to any balance of any deposit account as a condition of enforcing its rights
against any of the Collateral.

         4.8      Indemnification. In any suit, proceeding or action brought by
                  ---------------
or against the Lender relating to the Collateral, the Borrower will save,
indemnify and keep the Lender harmless from and against all reasonable expense,
loss or damage suffered by reason of any defense, set-off, counterclaim,
recoupment or reduction of liability whatsoever of any obligor thereunder,
arising out of a breach by the Borrower of any obligation thereunder or arising
out of any other agreement, indebtedness or liability at any time owing to or
in favor of such obligor or its successors from the Borrower, and all such
obligations of the Borrower shall be and remain enforceable against and only
against the Borrower and shall not be enforceable against the Lender. The
foregoing obligation of the Borrower to indemnify the Lender shall survive the
payment of the Loans and the termination of this Agreement but shall not extend
to any suit, proceeding or action arising out of the Lender's gross negligence
or willful misconduct.

         ARTICLE 5.  BORROWER'S REPRESENTATIONS AND WARRANTIES.

Revolving Loan to Borrower, Borrower makes the following representations and

all applicable laws, ordinances, rules, regulations, orders and other
requirements of any governmental authority or arbitrator, and with all terms and
conditions of its Governance Documents, and with each agreement binding upon or
affecting Borrower or any of its properties. Borrower is not in default with
respect to any Debt. Borrower will take all necessary actions to remain in full
compliance with such laws, ordinances, rules, regulations, orders and any other
requirements, the Governance Documents and all other agreements. Should Borrower
be deemed by any governmental authority or deem itself to be in violation of any
relevant law, ordinance, rule, regulation, orders or other requirement,
Governance Document or agreement, Borrower shall notify the Lender promptly of
such violation and take all necessary remedial actions. Without limiting the
generality of the foregoing, Borrower represents to Lender that: (1) Borrower
has previously disclosed to Lender all of Borrower's activities that involve the
use, manufacturing, storage, disposal, emission, discharge, generation or
transportation of Hazardous Wastes, Toxic Substances or other materials
regulated by Environmental Laws; (2) Borrower has complied and is in full
compliance with all Environmental Laws; (3) Borrower maintains in full force and

property have been obtained, are in effect, have been complied with in all
material respects by Borrower, are free from challenge, and to the best of
Borrower's knowledge are fully assignable to the Lender for the purpose of
securing the Revolving Loan. Borrower has no knowledge and has not received any
notice to the effect that any product it manufactures or sells, or any service
it renders, or any process, method, know-how, trade secret, part or material it

Amended and Restated Loan Agreement Draft #4                                  16

interest in and to all Intellectual Property used in and material to the
operation of its business or, for such Intellectual Property that is not owned,
possesses adequate licenses or other legally enforceable rights to use the same.
The Borrower has no reason to believe that any valid basis exists upon which a
claim adversely affecting any such Intellectual Property may be asserted against
the Borrower or any subsidiary. To the best knowledge of the Borrower, no Person
is infringing upon the Intellectual Property used by the Borrower or any
subsidiary material to the operation of their respective businesses. The
Borrower has taken appropriate steps to protect the secrecy, confidentiality and
value of its and all subsidiaries' rights in and to such Intellectual Property
and to prevent others from using such Intellectual Property without consent.

pursuant to this Agreement or any of the Loan Documents, when viewed together,
contains or will contain any untrue statement of a fact material to the

fact necessary in order to make the statements contained herein or therein, or
furnished herewith or therewith, not misleading.

                  ------------------

been the surviving entity in a merger or acquired any business.

date on which this representation is made or deemed made; (i) no Termination

assumptions used to fund such Plans), whether or not vested, did not, as of the
last annual valuation date prior to the date on which this representation is
made or deemed made, exceed the current value of the assets of such Plan
allocable to such accrued liabilities.

                           c.       Neither the Borrower nor any of its

any liability under Sections 406, 409, 502(i), or 502(l) of ERISA or Section
4975 of the Code, or under any agreement or other instrument pursuant to which

purpose other than the purposes or purposes specified hereinabove.

         7.8      Other Agreements.  Enter into any  agreement or  undertaking

limitation, the purchase, sale or exchange of property or the rendering of any
service, with any Affiliate, except in the ordinary course of and pursuant to
the reasonable requirements of the Borrower's business and upon fair and
reasonable terms no less favorable to the Borrower than would be applicable in
a comparable arm's-length transaction with a Person not an Affiliate.

         ARTICLE 8.  COLLECTION, DEPOSIT AND ASSIGNMENT OF PAYMENTS.
         ----------------------------------------------------------

         8.1      Rights and Responsibilities in Collection of Accounts. The
                  -----------------------------------------------------
Lender shall not, under any circumstances, be liable for any error or omission
or delay of any kind occurring in the settlement, collection or payment of any
Accounts or any instrument received in payment thereof or for any damage
resulting therefrom. The Lender is authorized to accept the return of the goods
represented by any of the Accounts, without notice to or consent by Borrower,
or without discharging or in any manner affecting the Revolving Loan. Upon
receipt of any returned or rejected goods, Borrower shall immediately issue and
deliver a credit memo to the Lender with respect thereto or, at the Lender's
election, Borrower may set aside such goods, mark them in the Lender's name and
hold them in trust for the benefit of the Lender at Borrower's expense and,
upon the Lender's request, shall pay the Lender the sales price thereof. If the
Lender shall request Borrower to pay the sales price of such goods and Borrower
fails to pay forthwith the sales price to the Lender, the Lender may take
possession of such goods and sell or cause such goods to be sold at public or
private sale, at such prices, to such purchasers, and upon such terms as the
Lender deems advisable. Borrower shall remain liable to the Lender for any
deficiency and shall pay the costs and expenses of such sale, including
reasonable attorneys' fees. Borrower shall use its best efforts and shall take
any and all steps necessary to collect any Accounts which are not directly
assigned to the Lender, including without limitation, the filing and pursuit of
legal action in furtherance of said collection efforts. Borrower acknowledges
that any failure to comply with the requirements of this Section 8.2 shall
cause irreparable harm to the Lender for which the Lender has no adequate
remedy at law, and agrees that the Lender shall be entitled to injunctive or
other equitable relief to compel Borrower's compliance with the provisions of
this Section.

other action shall be initiated by or on behalf of any Customer, which is based
upon a claim or contest with respect to any Government Contract or Government
Account that, if adversely determined to the Borrower, would have a material
adverse effect on the Borrower's financial condition, as determined by the
Lender in its reasonable discretion; or

                           i.       any Government Contract is terminated
for default, provided that said Government Contract is material to the
financial performance of Borrower, said determination of materiality to be in
Lender's sole discretion; or

                           j.       any loss, theft, damage or destruction of

or Section 4975 of the Code, or under any agreement or other instrument
pursuant to which the Borrower or any of its subsidiaries or any ERISA

         9.2      Rights and Remedies of the Lender.  Upon the  occurrence  of

terminated, and declare the entire unpaid principal amounts of the Revolving
Loan, all interest accrued and unpaid thereon, and all other amounts payable

immediately due and payable (except that upon the occurrence of an Event of

the Borrower is the debtor, such acceleration shall occur automatically and
immediately without any declaration or other action on the part of the Lender)
whereupon the Revolving Loan, all such accrued interest, and

Amended and Restated Loan Agreement Draft #4                                  27

all such amounts shall become and be immediately due and payable, without
presentment, demand, protest or further notice of any kind, all of which are
hereby expressly waived by Borrower, anything contained herein or in any of the
other Loan Documents to the contrary notwithstanding;

                           b.       Take possession or control of, store, lease,
operate, manage, sell or otherwise dispose of all or any part of the Collateral
in accordance with the remedies provided to secured parties under the Uniform

taking possession of the Collateral, the Lender may enter the Borrower's
premises and otherwise proceed without legal process, and the Borrower shall on
the Lender's demand, promptly assemble and make the Collateral available to the
Lender at a place designated by the Lender. The Lender shall be entitled to
immediate possession of all books and records evidencing or pertaining to any
of the Collateral;

                           c.       Notify any or all Customers to make any
Payments due to Borrower from such Customers directly to the Lender. To
facilitate direct collection, Borrower hereby appoints the Lender and any
officer or employee of the Lender, as the Lender may from time to time
designate, as attorney-in-fact for Borrower to (i) receive, open and dispose of
all mail addressed to Borrower and take therefrom any Payments on or proceeds
of Accounts; (ii) take over Borrower's post office boxes or make such other
arrangements, in which Borrower shall cooperate, to receive Borrower's mail,
including notifying the post office authorities to change the address for
delivery of mail addressed to Borrower to such address as the Lender shall

endorse the name of Borrower on any invoice or bill of lading relating to any
of the Accounts, on verifications of Accounts sent to any Customer, to drafts
against any Customer, to assignments of Accounts, and to notices to any
Customer; and (v) do all acts and things necessary to carry out this Agreement
and the transactions contemplated hereby, including signing the name of
Borrower on any instruments required by law in connection with the transactions
contemplated hereby and on financing statements as permitted under the Uniform

attorney-in-fact shall be liable for any acts of commission or omission, or for
any error of judgment or mistake of fact or law of any such attorney-in-fact
unless such acts are due to willful misconduct. This power, being coupled with
an interest and given to secure an obligation, is irrevocable so long as the
Revolving Loan remains unsatisfied, or any Loan Document remains effective, as
solely determined by the Lender;

                           d.       In the Lender's own name, or in the name of
Borrower, demand, collect, receive, sue for and give receipts and releases for,
any and all amounts due on Accounts, but the Lender shall not, under any
circumstances, be liable for any error or omission or delay of any kind
occurring in the settlement, collection or payment of any Accounts or any
instrument received in payment thereof or for any damage resulting therefrom
unless caused by Lender's willful misconduct;

all of Borrower's permits, licenses, approvals, agreements and the like
relating to the Collateral or to Borrower's business to the Lender or to any
assignee of the Lender or to any purchaser of any of the Collateral;

                           g.       Obtain appointment of a receiver for all or
any of the Collateral, Borrower hereby consenting to the appointment of such a
receiver and agreeing not to oppose any such appointment. Any receiver so
appointed shall have such powers as may be conferred by the appointing
authority including any or all of the powers, rights and remedies which the
Lender is authorized to exercise by the Loan Documents, and shall have the
right to incur such obligations and to issue such certificates therefor as the
appointing authority shall authorize;

                           h.       Take any other action which the Lender
deems necessary or desirable to protect and realize upon its security interest
in the Collateral;

                           i.       Borrower acknowledges that any failure to
comply with its obligation regarding the Collateral, including (without
limiting the generality of the foregoing) granting of Assignments and
collection of the Accounts, shall cause irreparable harm to the Lender for
which the Lender has no adequate remedy at law, and agrees that the Lender
shall be entitled to specific performance, an injunction or other equitable
relief to enforce the Borrower's obligations under this Agreement; and

                           j.       In addition to the foregoing, and not in
substitution therefor, exercise any one or more of the rights and remedies
exercisable by the Lender under other provisions of this Agreement, under any
of the other Loan Documents, or provided by applicable law (including, without
limiting the generality of the foregoing, the Uniform Commercial Code).

         9.3      Application of Proceeds.  Any proceeds from the collection or
                  -----------------------
sale or other disposition of the Collateral shall be applied in the following
order of priority:

                  First, to the payment of all expenses of collecting, storing,
                  -----
leasing, operating, managing, selling or disposing of the Collateral, and to the
payment of all sums which the Lender may be required or may elect to pay, if
any, for taxes, assessments, insurance and other charges upon such Collateral or
any part thereof, and of all other payments which the Lender may be required or
authorized to make under any provision of this Agreement or of any other Loan
Document (including in each such case reasonable legal costs and attorneys' fees
and expenses);

                  Second, to the payment of all obligations on the Revolving
                  ------

                  Third, to the payment of any surplus then remaining to
                  -----
Borrower, unless otherwise provided by law or directed by a court of competent
jurisdiction; provided that Borrower shall be liable for any deficiency if the
proceeds of the Collateral are insufficient to satisfy all obligations due to
the Lender.

         9.4      Collection/Enforcement Costs. Borrower shall pay all costs and
                  ----------------------------

under this Agreement and the other Loan Documents, including without limitation,
reasonable legal costs and attorneys' fees (whether or not suit is instituted)

the parties hereto with respect to the matters contemplated herein, supersede
all prior oral and written agreements with respect to the matters contemplated
herein, and may not be modified, deleted or amended except by written instrument
executed by the parties. All terms of this Agreement and of the other Loan
Documents shall be binding upon, and shall inure to the benefit of and be
enforceable by, the parties hereto and their respective successors and assigns;
however, Borrower may not assign or transfer any of its rights or obligations

both, would constitute an Event of Default hereunder, the Lender is irrevocably
authorized, at any time or times without prior notice to Borrower, to set off,
appropriate and apply any and all deposits, credits, indebtedness or claims at
any time held or owing by the Lender to or for the credit or the account of
Borrower, in such amounts as the Lender may elect, against and on account of the
obligations and liabilities of Borrower to the Lender hereunder or under any of
the other Loan Documents, whether or not the Lender has made any demand for
payment, and although such obligations and liabilities may be contingent or
unmatured.

         10.10    Construction. This Agreement and the other Loan Documents, the
                  ------------

choice of law rules thereof).  Each party hereto hereby acknowledges that all
parties hereto participated equally in the negotiation and drafting of this
Agreement and that, accordingly, no court construing this Agreement shall
construe it more stringently against one party than against the other.

         10.11    Pronouns. All pronouns and any variations thereof shall be
                  --------
deemed to refer to the masculine, feminine, neuter, singular or plural, as the

         10.12    Headings. Article, section and subsection headings contained
                  --------
in this Agreement are inserted for convenience of reference only, shall not be
deemed to be a part of this Agreement for any purpose, and shall not in any way
define or affect the meaning, construction or scope of any of the provisions
hereof.

         10.13    Payments. If any payment or performance of any of the
                  --------
obligations under this Agreement or any of the other Loan Documents becomes due
on a day other than a Business Day, the due date shall be extended to the next
succeeding Business Day, and interest thereon (if applicable) shall be payable
at the then applicable rate during such extension.

         10.14    Accounting Terms. All accounting terms used herein which are
                  ----------------
not otherwise expressly defined in this Agreement shall have the meanings
respectively given to them in accordance with GAAP in effect on the date of this
Agreement. Except as otherwise provided herein, all financial computations made
pursuant to this Agreement shall be made in accordance with GAAP, consistently
applied, and all balance sheets and other financial statements shall be prepared
in accordance with GAAP, consistently applied. Except as otherwise provided
herein, whenever reference is made in any provision of this Agreement to a
balance sheet or other financial statement or the information depicted therein
for performing a financial computation, such terms shall mean the most recent
consolidated balance sheet or other financial statement received by the Lender
pursuant to the terms hereof.

         10.15    Execution. To facilitate execution, this Agreement and any of
                  ---------
the other Loan Documents may be executed in as many counterparts as may be
required; and it shall not be necessary that the signature of, or on behalf of,
each party, or the signatures of all persons required to bind any party, appear
on each counterpart; but it shall be sufficient that the signature of, or on
behalf of, each party, or the signatures of the persons required to bind any
party, appear on one or more of the counterparts. All counterparts shall
collectively constitute a single agreement. It shall not be necessary in making
proof of this Agreement or any other Loan Document to produce or account for
any particular number of counterparts; but rather any number of counterparts
shall be sufficient so long as those counterparts contain the respective
signatures of, or on behalf of, all of the parties hereto.

         10.16    Consent to Jurisdiction. Subject to any provision of this
                  -----------------------
Agreement requiring that disputes be submitted to arbitration, the
Borrower irrevocably consents to the jurisdiction of any state or
federal court sitting in the Commonwealth of Virginia over any suit,
action, or proceeding arising out of or relating to this Agreement or

fullest extent permitted by law, any objection that the Borrower may
now or hereafter have to the laying of venue of any such suit,
action, or

proceeding brought in any such court, or any claim that any such
suit, action, or proceeding brought in any such court has been
brought in an inconvenient forum. Final judgment in any such suit,
action, or proceeding brought in any such court shall be conclusive
and binding upon the Borrower.

         10.17    Service of Process. The Borrower consents to process being
                  ------------------
served in any suit, action or proceeding by mailing a copy thereof by

agrees that such service (i) shall be deemed in every respect effective service
of process upon the Borrower in any such suit, action or proceeding and (ii)
shall, to the fullest extent permitted by law, be taken and held to be valid
personal service upon and personal delivery to the Borrower. Nothing in this
Section shall affect the right of the Lender to serve process in any manner
permitted by law, or limit any right that the Lender may have to bring
proceedings against the Borrower in the courts of any jurisdiction or to
enforce in any lawful manner a judgment obtained in one jurisdiction in any
other jurisdiction.

sole and absolute discretion. Borrower also hereby consents to and agrees that
Lender may sell or assign any rights of Lender in any or all of the Loan
Documents pursuant to such terms and conditions as may be acceptable to Lender
in its sole and absolute discretion, to any interested Person, and nothing in
this Agreement or the other Loan Documents shall prevent, delay or otherwise
impede or effect the right of Lender to immediately sell or assign any rights of
Lender in the Loan Documents on such terms as it deems acceptable.

                  -----------

         WITHIN 90 DAYS OF THE DEMAND FOR ARBITRATION; FURTHER, THE ARBITRATOR

         REMEDIES NOR THE INSTITUTION OR MAINTENANCE OF AN ACTION FOR
         FORECLOSURE OR PROVISIONAL OR ANCILLARY REMEDIES SHALL CONSTITUTE A
         WAIVER OF THE RIGHT OF ANY PARTY, INCLUDING THE CLAIMANT IN ANY SUCH
         ACTION, TO ARBITRATE THE MERITS OF THE CONTROVERSY OR CLAIM OCCASIONING
         RESORT TO SUCH REMEDIES.
