Item 5.   Other

(a)

  Hadron, Inc. (the "Company") entered into a Loan and Security
Agreement dated June 29, 1999 (the "Loan Agreement") among the
Company, United Bank and each of the Company's wholly owned
subsidiaries, Avenue Technologies, Inc., Vail Research and
Technology Corporation, Sycom Services, Inc., and Engineering &
Information Services, Inc.  The Loan Agreement provides the Company
with a one-year $1.5 million line of credit facility (the "Credit
Facility") and a three-year $1.5 million term loan (the "Term
Loan").  Interest on each of the facilities is at the prime rate
plus 150 basis points.  Dr. C.W. Gilluly, Chairman of the Company,
and his wife have personally guaranteed the Term Loan.

  The Credit Facility replaces the Company's previous line
of credit with Century National Bank.  Proceeds from the Term Loan
were used to repay the Company's $1.5 million in short-term notes
that were issued in connection with the Company's May 1999
acquisition of Avenue Technologies, Inc. ("ATI").  The Term Loan
provides for monthly principal payments of $41,667, plus interest.

  The Term Loan and the Credit Facility are secured by the
accounts receivable and other assets of the Company.  In addition,
the convertible notes issued by the Company to the former
shareholders of ATI in connection with the Company's acquisition of
ATI were subordinated to the Company's obligations under the Term
Note and the Credit Facility.

(b)

  During June 1999, George E. Fowler, S. Amber Gordon, Donald E.
Jewell, Robert J. Lynch and Donald E. Ziegler, all of whom are
officers or directors of the Company, converted  their respective
$24,000 two-year convertible promissory notes into 40,000 shares
each of the Company's common stock at the stated exercise price of
$.60 per share.


(c)
  In June 1999, Dr. C.W Gilluly exercised warrants to acquire 400,000
shares of the Company's common stock at a purchase price of $.25 per share.

                        COMMERCIAL NOTE

                        IMPORTANT NOTICE

THIS INSTRUMENT CONTAINS A CONFESSION OF JUDGMENT PROVISION WHICH
CONSTITUTES A WAIVER OF IMPORTANT RIGHTS YOU MAY HAVE AS A DEBTOR
AND ALLOWS THE CREDITOR TO OBTAIN A JUDGMENT AGAINST YOU WITHOUT
ANY FURTHER NOTICE.

$1,500,000.00                                        June 29, 1999

     FOR VALUE RECEIVED, the undersigned (the "Borrower")
jointly and severally promise to pay to the order of UNITED BANK
(the "Bank," which term shall include any holder of this Note)
without offset, at the Bank's office located at 2071 Chain Bridge
Road, Vienna, Virginia 22182 (or at such other address as the
Bank shall designate), the principal sum of One Million Five
Hundred Thousand and no/100 Dollars ($1,500,000.00), together
with interest on the principal balance outstanding from time to
time at the rate provided in this Note.

     INTEREST RATE.  This Note shall bear interest on the
principal balance outstanding from time to time, from the date of
this Note until paid in full, a variable rate per annum equal, at
all times, to the Prime Rate plus 1.50%.  The "Prime Rate" shall
mean that variable rate of interest published in  The Wall Street
Journal from time to time as the domestic prime rate under the
heading "Money Rates".  Adjustments to a variable interest rate
will be effective, without prior notice, as of the effective date
of any change in the Prime Rate. Interest shall be computed on
the basis of a 360 day year, counting the actual number of days
elapsed.  If The Wall Street Journal shall cease to publish the
Prime Rate, the term "Prime Rate" shall thereafter mean the
rate announced from time to time by the Bank as its prime rate of
interest and evidenced by a certificate signed by any officer of
the Bank setting forth said prime rate of interest in effect on
any given date, whether or not such rate is otherwise published
or announced.

     PAYMENT TERMS.  The Borrower agrees to pay this Note as
follows:

     (a)     In installments of $41,666.67 each, plus interest,
beginning July 31, 1999, and continuing on the last day of each
consecutive month thereafter; provided, however,

     (b)     principal, interest and all other charges shall be
due and payable in full on June 30, 2002.

     PREPAYMENT.  The Borrower may pay the whole or any part
of the outstanding indebtedness evidenced by this Note at any
time without penalty by paying the principal amount to be prepaid
together with accrued interest thereon to the date of prepayment.
<PAGE>
     DEFAULT.  Each of the following events or conditions
shall constitute a default ("Default") under this Note:

     (a)     the failure to make any payment of principal,
interest or any other amount due under this Note when such
payment is due;

     (b)     any default under the terms of any of the Loan
Documents, or the failure to perform or observe any warranty,
covenant, or other condition of any of the Loan Documents;

     (c)     any default by the Borrower or any indorser or
guarantor of the payment of this Note with respect to any
indebtedness to the Bank (other than this Note);

     (d)     the death, incompetence, merger, consolidation,
reorganization, dissolution, or termination of existence of any
Party; or the pledge, lease or other disposition, without the
prior written approval of the Bank, of all or substantially all
of the assets of any Party;

     (e)     any change, or any transaction which results or
could result in a change, in the Control of any Party;

     (f)     the determination by the Bank that any warranty,
representation, certificate, statement or information provided by
any Party or any Person on behalf of a Party to the Bank in
connection with any of the Loan Documents, or to induce the Bank
to make or extend or modify the terms of the loan evidenced by
this Note, was false or misleading, or that any Party or any
Person on behalf of a Party failed to provide or disclose any
material facts or information, which failure rendered such
warranty, representation, certificate, statement or information
materially misleading;

     (g)     the inability of any Party to pay its debts as
they mature, the insolvency of any Party, the filing of a
petition by or against any Party under the provisions of any
bankruptcy, reorganization, arrangement, insolvency, liquidation
or similar law for relief of debtors, the appointment or
application for appointment of any receiver for any Party or the
property of any Party, the issuance or service of any attachment,
levy, garnishment, tax lien or similar process against any Party
or the property of any Party, the entry of a judgment against any
Party, or an assignment for the benefit of creditors by any
Party;

     (h)     any agreement or other document granting the
Bank security for the payment of this Note shall cease for any
reason to be in full force and effect as such security with the
priority stated to be created thereby, or the grantor of such
security shall contest the validity or enforceability of the
security or deny that it has any further liability or obligation
under such agreement or other document; provided that the
Borrower shall have the opportunity to cure any such cessation in
the effect or priority of such security resulting from any act or
omission by the Bank for a period of ten (10) days after notice
thereof from the Bank to the Borrower;
<PAGE>
     (i)     any indorsement or guaranty of the payment of
this Note shall cease for any reason to be in full force and
effect, or any indorser or guarantor shall contest the validity
or enforceability of the indorsement or guaranty or deny that it
has any further liability or obligation under the indorsement or
guaranty; or

     (j)     the determination by the Bank that (i) there has
occurred a material adverse change in the financial condition of
any Party, (ii) the value of any property securing this Note has
been materially impaired, or (iii) there has occurred or
developed an event or condition which materially impairs the
prospect of payment or performance of any of the obligations of
any Party under the Loan Documents.

     ACCELERATION.  At the option of the Bank, upon the
occurrence of a Default as defined above, the full amount
remaining unpaid on this Note shall become immediately due and
payable without presentment, demand or notice of any kind; and
the Bank may exercise any or all remedies available to it under
applicable law and the Loan Documents.

     CONFESSION OF JUDGMENT.  The Borrower appoints Philip
C. Baxa, Esquire, and Mary C. Zinsner, Esquire, either of whom
may act, as its duly constituted attorney-in-fact with authority,
in the name, place, and stead of the Borrower, to confess
judgment in the office of the clerk of the Circuit Court of
Fairfax County, Virginia against it, in the full amount due under
this Note, upon the occurrence of a Default under this Note.

     ACCOUNT RECORD.  The Bank shall maintain records of the
dates and amounts of advances of principal and payments of
principal and interest, the date to which interest has been paid,
accrued interest, the unpaid principal balance, and any other
account information.  Such records shall be maintained
unilaterally by the Bank without notice to the Borrower and shall
be presumed to be correct, provided, however, any failure of the
Bank to maintain such records or any error therein or in any
notice hereunder shall not in any manner affect the obligation of
the Borrower to pay this Note in accordance with the terms
hereof.

     IMMEDIATELY AVAILABLE FUNDS.  The principal of and
interest on this Note shall be payable in immediately available
funds in lawful money of the United States which shall be legal
tender for public and private debts at the time of payment.
The making of any payment in other than immediately available
funds which the Bank, at its option, elects to accept shall be
subject to collection, and interest shall continue to accrue until
the funds by which payment is made are available to the Bank for its use.
<PAGE>
     ADJUSTMENT TO BILLING NOTICE.  If, because a variable
interest rate or the outstanding principal balance of this Note
changes between the date of a billing notice and the end of a
billing period or the Date of Maturity, the actual amount due and
payable is different from the amount billed, then the amount
billed must be paid.  The next following billing notice shall be
adjusted by the amount of the difference, or a supplemental
billing notice or rebate, as the case may be, shall be sent to
the Borrower following the Date of Maturity.  A supplemental
billing notice following the Date of Maturity shall be
immediately due and payable in full.

     APPLICATION OF PAYMENTS.  Payments will be applied to
interest, late charges and other charges due at the time such
payments are received, and principal, in that order.  All
payments shall be applied to satisfaction of scheduled payments
in the order in which they become due.

     WAIVER.  The Borrower and any indorser of this Note (i)
waive presentment, demand, protest and notice of dishonor and
protest, (ii) waive the benefit of their homestead exemptions as
to this debt, (iii) waive any right which they may have to
require the Bank to proceed against any other Party or any
collateral given to secure the payment of this Note, and (iv)
agree that, without notice to the Borrower or any indorser and
without affecting the liability of the Borrower or any indorser,
the Bank, at any time or times, may grant extensions of the time
for any payment due on this Note or any other indulgence or
forbearance, release any Party from the obligation to make
payments on this Note, permit the renewal of this Note, or permit
the substitution, exchange or release of any security for this
Note.

     LATE CHARGE; ATTORNEYS' FEES.  If the Borrower fails to
pay any amount due under this Note within 10 days of the date
due, the Borrower shall pay to the Bank on demand a late charge
equal to five percent (5%) of the amount due.  The Borrower shall
pay to the Bank on demand all costs incurred by the Bank, and
reasonable attorneys' fees, in the collection or enforcement of
this Note in the event of Default, whether or not suit is
brought.

     SET-OFF.  The Bank will have the right upon the
occurrence of a Default, in addition to all other remedies
permitted by law (including, without limitation, other rights of
set-off), to set off the amount now or hereafter due under this
Note or due under any other obligation of the Borrower to the
Bank against any and all accounts, credits, money, securities, or
other property now or hereafter on deposit with, held by, or in
the possession of the Bank to the credit or for the account of
the Borrower, without notice to or consent by the Borrower.  In
addition to the right of set-off, to secure the payment of this
Note the Borrower assigns and grants to the Bank a security
interest in all accounts, credits, money, securities, or other
property now or hereafter on deposit with, held by, or in the
possession of the Bank to the credit or for the account of the
Borrower.

occurrence of a Default as defined above, the full amount
remaining unpaid on this Note shall become immediately due and

billed must be paid.  The next following billing notice shall be

III.  THE SECURITY INTERESTS.

     (A)  Grant of Security Interests.  To secure the due and
punctual payment of all Obligations, howsoever created, arising
or evidenced, whether direct or indirect, absolute or contingent,
now or hereafter existing or due or to become due, in accordance
with the terms thereof and to secure the due and punctual
performance of all of the obligations of the Borrower contained
in the Notes and this Agreement and in the other Loan Documents
to which it is a party and in order to induce the Bank to enter
into this Agreement and make the Advances and the Term Loan
provided for therein and herein in accordance with the terms
hereof and thereof, the Borrower hereby grants to the Bank a
security interest in all of the Borrower's right, title and
interest in, to and under the following, whether now existing or
hereafter acquired (all of which are herein collectively called
the "Collateral"):

     (1)  all Receivables;

     (2)  all Other Intangibles;

     (3)  all Equipment;

     (4)  all Inventory;

     (5)  to the extent not included in the foregoing, all
other personal property, whether tangible or intangible, and
wherever located, including, but not limited to, the balance of
every deposit account now or hereafter existing of the Borrower
with any bank and all monies of the Borrower and all rights to
payment of money of the Borrower;

     (6)  to the extent not included in the foregoing, all
books, ledgers and records and all computer programs, tapes,
discs, data processing software, transaction files, master files
and related property and rights (including computer and
peripheral equipment) necessary or helpful in enforcing,
identifying or establishing any item of Collateral; and

      (7)  to the extent not otherwise included, all Proceeds
and products of any or all of the foregoing, whether existing on
the date hereof or arising hereafter.
<PAGE>
     (B)  Continuing Liability of the Borrower.  Anything herein
to the contrary notwithstanding, the Borrower shall remain liable
to observe and perform all the terms and conditions to be
observed and performed by it under any contract, agreement,
warranty or other obligation with respect to the Collateral, and
shall do nothing to impair the security interests herein granted.
The Bank shall not have any obligation or liability under any
such contract, agreement, warranty or obligation by reason of or
arising out of this Agreement or the receipt by the Bank of any
payment relating to any Collateral, nor shall the Bank be
required to perform or fulfill any of the obligations of the
Borrower with respect to the Collateral, to make any inquiry as
to the nature or sufficiency of any payment received by it or the
sufficiency of the performance of any party's obligations with
respect to any Collateral.  Furthermore, the Bank shall not be
required to file any claim or demand to collect any amount due,
or to enforce the performance of any party's obligations with
respect to, the Collateral.

     (C)  Sales and Collections.

     (1)   The Borrower is authorized (a) to sell in the
ordinary course of its business for fair value and on an arm's-
length basis any of its Inventory normally held by it for such
purpose and (b) to use and consume, in the ordinary course of its
business, any raw materials, supplies and materials normally held
by it for such purpose.  The Bank may upon the occurrence of any
Default, without cause or notice, curtail or terminate such
authority at any time.

     (2)  All Account Debtors shall be notified to make
payments under Receivables constituting "Remittances" under the
Lockbox Agreement directly to the Bank in accordance with the
terms of the Lockbox Agreement.  The Borrower will use all
reasonable efforts to cause each Account Debtor to comply with
the foregoing instruction.  In furtherance of the foregoing, the
Borrower authorizes the Bank (a) to ask for, demand, collect,
receive and give acquittances and receipts for any and all
amounts due and to become due under any Collateral and, in the
name of the Borrower or its own name or otherwise, (b) to take
possession of, indorse and collect any checks, drafts, notes,
acceptances or other instruments for the payment of moneys due
under any Collateral and (c) to file any claim or take any other
action in any court of law or equity or otherwise which it may
deem appropriate for the purpose of collecting any amounts due
under any Collateral.  The Bank shall have no obligation to
obtain or record any information relating to the source of such
funds or the obligations in respect of which payments have been
made, other than as required by the Lockbox Agreement.
<PAGE>
     (D)  Segregation of Proceeds.

     (1)  The Bank shall have the right at any time
(regardless of whether or not a Default shall have occurred) to
cause to be opened and maintained at the principal office of the
Bank a non-interest bearing bank account (the "Cash Collateral
Account") which will contain only Proceeds (other than those
collected pursuant to the Lockbox Agreement).  Any cash proceeds
(as such term is defined in Section 9-306(1) of the UCC) received
by the Bank from the Borrower pursuant to paragraph (2) of this
subsection (D), whether consisting of checks, notes, drafts,
bills of exchange, money orders, commercial paper or other
Proceeds received on account of any Collateral, shall be promptly
deposited in the Cash Collateral Account, and until so deposited
shall be held in trust for and as the Bank's property and shall
not be commingled with any funds of the Borrower not constituting
Proceeds of Collateral.  The name in which the Cash Collateral
Account is carried shall clearly indicate that the funds
deposited therein are the property of the Borrower, subject to
the security interest of the Bank hereunder.  Such Proceeds, when
deposited, shall continue to be security for the Obligations and
shall not constitute payment thereof until applied as hereinafter
provided.  The Bank shall have sole dominion and control over the
funds deposited in the Cash Collateral Account, and such funds
may be withdrawn therefrom only by the Bank; provided, however,
that until a Default shall occur, all collected funds on deposit
in the Cash Collateral Account, or so much thereof as is not
required to make payment of the Obligations which have become due
and payable, shall be withdrawn by the Bank on the Business Day
next following the day on which the Bank considers the funds
deposited therein to be collected funds and disbursed to the
Borrower or its order.

     (2)  Upon notice by the Bank to the Borrower that
the Cash Collateral Account has been opened, the Borrower shall
cause all cash Proceeds collected by it pursuant to paragraph
(1), above, to be delivered to the Bank forthwith upon receipt,
in the original form in which received (with such indorsements or
assignments as may be necessary to permit collection thereof by
the Bank), and for such purpose the Borrower hereby irrevocably
authorizes and empowers the Bank, its officers, employees and
authorized agents to indorse and sign the name of the Borrower on
all checks, drafts, money orders or other media of payment so
delivered, and such indorsements or assignments shall, for all
purposes, be deemed to have been made by the Borrower prior to
any indorsement or assignment thereof by the Bank.  The Bank may
use any convenient or customary means for the purpose of
collecting such checks, drafts, money orders or other media of
payment.

     (E)  Verification of Receivables.  The Bank shall have the
right to make test verifications of Receivables in any manner and
through any medium that it considers advisable, and the Borrower
agrees to furnish all such assistance and information as the Bank
may require in connection therewith.  The Borrower at its expense
will cause either independent certified public accountants or, if
agreeable to the Bank in its sole discretion, the Borrower's
chief financial officer, to furnish to the Bank at any time and
from time to time promptly upon the Bank's request, the following
<PAGE>
reports:  (i) a reconciliation of all Receivables, (ii) an aging
of all Receivables, (iii) trial balances and (iv) a test
verification of such Receivables as the Bank may request.

     (F)  Release of Collateral.

     (1)  The Borrower may sell or realize upon or
transfer or otherwise dispose of Collateral as permitted by
Section VI(B)(13), and the security interests of the Bank in such
Collateral so sold, realized upon or disposed of (but not in the
Proceeds arising from such sale, realization or disposition)
shall cease immediately upon such sale, realization or
disposition, without any further action on the part of the Bank.
The Bank, if requested in writing by the Borrower but at the
expense of the Borrower, is hereby authorized and instructed to
deliver to the Account Debtor or the purchaser or other
transferee of any such Collateral a certificate stating that the
Bank no longer has a security interest therein, and such Account
Debtor or such purchaser or other transferee shall be entitled to
rely conclusively on such certificate for any and all purposes.

     (2)  Upon the payment in full of all of the
Obligations and if there is no commitment by the Bank to make
further Advances, incur obligations or otherwise give value, the
Bank will (as soon as reasonably practicable after receipt of
notice from the Borrower requesting the same but at the expense
of the Borrower) send the Borrower, for each jurisdiction in
which a UCC financing statement is on file to perfect the
security interests granted to the Bank hereunder, a termination
statement to the effect that the Bank no longer claims a security
interest under such financing statement.

IV.	CONDITIONS PRECEDENT.

V.	REPRESENTATIONS AND WARRANTIES.

     Each Borrower represents and warrants that:

     (A)  Corporate Existence and Power.  Said Borrower is duly
organized, validly existing and in good standing under the laws
of the state of its incorporation, and has all powers and all
material governmental licenses, authorizations, consents and
approvals required to carry on its business as now conducted.
Said Borrower is duly qualified as a foreign corporation,
licensed and in good standing in each jurisdiction where
qualification or licensing is required by the nature of its
business or the character and location of its property, business
or customers and in which the failure to so qualify or be
licensed, as the case may be, in the aggregate, could have a
material adverse effect on the business, financial position,
results of operations, properties or prospects of said Borrower.
<PAGE>
     (B)   Organizational and Governmental Authorization;
Contravention.  The execution, delivery and performance by said
Borrower of this Agreement, the Notes and the other Loan
Documents to which it is a party are within its organizational
power, have been duly authorized by all necessary action, require
no action by or in respect of, or filing with, any governmental
body, agency or official and do not contravene, or constitute
(with or without the giving of notice or lapse of time or both) a
default under, any provision of applicable law or of the
organizational documents of said Borrower or of any agreement,
judgment, injunction, order, decree or other instrument binding
upon or affecting said Borrower or result in the creation or
imposition of any Lien (other than the Lien of this Agreement and
the other Loan Documents) on any of its assets.

     (C)  Binding Effect.  This Agreement constitutes a valid and
binding agreement of said Borrower and the Notes, when executed
and delivered in accordance with this Agreement, will constitute
valid and binding obligations of said Borrower, in each case
enforceable against said Borrower in accordance with its terms,
except as (1) the enforceability hereof and thereof may be
limited by bankruptcy, insolvency or similar laws affecting
creditors' rights generally and (2) rights of acceleration and
the availability of equitable remedies may be limited by
equitable principles of general applicability.

     (D)  Title to Collateral.  Except for the security interests
granted to the Bank pursuant to this Agreement, the Borrower is
the sole owners of each item of the Collateral, having good and
marketable title thereto, free and clear of any and all Liens,
except Permitted Liens.

     (E)  Validity, Perfection and Priority of Security
Interests.

     (1)  By complying with Section VI(B)(1), said
Borrower will have created a valid security interest in favor of
the Bank in all existing Collateral and in all identifiable
Proceeds of such Collateral, which security interest (except in
respect of motor vehicles for which the exclusive manner of
perfecting a security interest therein is by noting such security
interest on the certificate of title in accordance with local
law) would be prior to the claims of a trustee in bankruptcy
under Section 544(a) of the federal Bankruptcy Code.  Continuing
compliance by said Borrower with the provisions of Section
VI(B)(2) will also (a) create valid security interests in all
Collateral acquired after the date hereof and in all identifiable
Proceeds of such Collateral and (b) cause such security interests
in all Collateral and in all Proceeds which are (i) identifiable
cash Proceeds of Collateral covered by financing statements
required to be filed hereunder, (ii) identifiable Proceeds in
which a security interest may be perfected by such filing under
the UCC and (iii) any Proceeds in the Cash Collateral Account and
the account used in connection with the Lockbox Agreement to be
duly perfected under the UCC, in each case prior to the claims of
a trustee in bankruptcy under the federal Bankruptcy Code.
<PAGE>
     (2)  The security interests of the Bank in the
Collateral rank first in priority.  Other than financing
statements or other similar documents perfecting the security
interests of the Bank, no financing statements or similar
documents covering all or any part of the Collateral are on file
or of record in any government office in any jurisdiction in
which such filing or recording would be effective to perfect a
security interest in such Collateral, nor is any of the
Collateral in the possession of any person (other than said
Borrower) asserting any claim thereto or security interest
therein.

     (F)  Enforceability of Receivables and Other Intangibles.
To the best knowledge of said Borrower, each Receivable and Other
Intangible is a valid and binding obligation of the related
Account Debtor in respect thereof, enforceable in accordance with
its terms, except as such enforceability may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium or
similar laws affecting the enforcement of creditors' rights
generally and by general provisions of equity (regardless of
whether such enforceability is considered in a proceeding in
equity or at law), and complies with any applicable legal
requirements.

     (G)  Place of Business; Location of Collateral.  Appendix 1
hereto correctly sets forth said Borrower's current chief
executive office, any and all chief executive offices of said
Borrower within the previous four (4) months, all other places of
business of said Borrower and the offices of said Borrower where
records concerning Receivables and Other Intangibles are kept.
Appendix 2 hereto correctly sets forth the location of all
Equipment and Inventory, other than rolling stock, aircraft,
goods in transit and Inventory sold in the ordinary course of
business as permitted by Section VI(B)(13) of this Agreement.
Except as otherwise specified in Appendix 2 hereto, all Inventory
and Equipment has been located at the address specified on said
Appendix 2 at all times during the four-month period prior to the
date hereof while owned by said Borrower.  All Inventory has been
and will be produced in compliance with the Fair Labor Standards
Act, 29 U.S.C. SS 201-219.  No Inventory is evidenced by a
negotiable document of title, warehouse receipt or bill of
lading.  No non-negotiable document of title, warehouse receipt
or bill of lading has been issued to any person other than said
Borrower, and said Borrower has retained possession  of all of
such non-negotiable documents, warehouse receipts and bills of
lading.  No amount payable under or in connection with any of the
Collateral is evidenced by promissory notes or other instruments.

    (H)  Trade Names.  Any and all trade names, division names,
assumed names or other names under which said Borrower transacts,
or within the four-month period prior to the date hereof has
transacted, business are specified on Appendix 3 hereto.
<PAGE>
    (I)  Financial Information.

     (1)  The most recent fiscal year end balance sheet
of said Borrower and the related financial statements, reported
on by said Borrower's independent public accountants, copies of
which have been delivered to the Bank, fairly present, in
conformity with GAAP, the financial position of said Borrower as
of the date thereof and its results of operations and cash flows
for such fiscal year.  As of the date of such financial
statements, said Borrower did not have any material contingent
obligation, contingent liability or liability for Taxes, long-
term lease or unusual forward or long-term commitment, which is
not reflected in any of such financial statements or notes
thereto.

     (2)  Since the date of the most recent balance sheet,
there has been no material adverse change in the business,
financial position, results of operations or prospects of said
Borrower.

     (J)  Litigation.  There is no action, suit or proceeding
pending against, or to the knowledge of said Borrower threatened
against or affecting, said Borrower before any Government in
which there is a reasonable possibility of an adverse decision
which could materially adversely affect the business, financial
position or results of operations of said Borrower or which in
any manner draws into question the validity of this Agreement,
the Notes, or any other Loan Document and there is no basis known
to said Borrower for any such action, suit or proceeding.

     (K)  Marketable Title.  Said Borrower has good and
marketable title to all its properties and assets subject to no
Lien, except Permitted Liens.

     (L)  Filings.  All actions by or in respect of, and all
filings with, any governmental body, agency or official required
in connection with the execution, delivery and performance of
this Agreement, the Notes and the other Loan Documents, or
necessary for the validity or enforceability thereof or for the
protection or perfection of the rights and interests of the Bank
thereunder, will, prior to the date of delivery thereof, have
been duly taken or made, as the case may be, and will at all
times thereafter remain in full force and effect.

     (M)  Regulation U.  The proceeds of the Term Loan and the
Advances will be used by the Borrower only for the purposes set
forth in Section VI(C)(14) hereof.  None of the proceeds of any
Advance or the Term Loan will be used, directly or indirectly,
for the purpose of purchasing or carrying any "margin stock" or
for the purpose of reducing or retiring any indebtedness which
was originally incurred to purchase or carry margin stock or for
any other purpose which might constitute the loans evidenced by
the Notes, or any Advance, a "purpose credit" within the meaning
of Regulation U or Regulation X of the Board of Governors of the
Federal Reserve System.
<PAGE>
     (N)  Taxes.  Said Borrower has filed all United States
Federal income Tax returns and all other material Tax returns
which are required to be filed by it and has paid all Taxes due
pursuant to such returns or pursuant to any assessment received
by the Borrower.  The charges, accruals and reserves on the books
of said Borrower in respect of Taxes or other governmental
charges are adequate.

     (O)  Year 2000.   To the knowledge of said Borrower, the
computer systems used by and licensed by said Borrower and its
Subsidiaries are Year 2000 Compliant.  As used herein, "Year
2000 Compliant" means that neither performance nor functionality
of any computer hardware or software is affected by dates prior
to, during, or after, the year 2000; and, in particular, (i) no
value for current date will cause any interruption in operation,
(ii) date-based functionality must behave consistently for dates
prior to, during, and after, the year 2000, (iii) in all
interfaces and data storage, the century in any date must be
specified either explicitly or by unambiguous algorithms or
interfacing rules, and (iv) the year 2000 must be recognized as a
leap year.

     (P)  Disclosure.  None of this Agreement, any other Loan
Document, any schedule or exhibit thereto or document,
certificate, report, statement or other information furnished to
the Bank in connection herewith or therewith or in connection
with the consummation of the transactions contemplated hereby or
thereby contains any material misstatement of fact or omits to
state a material fact necessary to make the statements contained
herein or therein not misleading.  There is no fact materially
adversely affecting the assets, business, financial position,
results of operations or prospects of the Borrower which has not
been set forth in a footnote included in the financial statements
referred to in subsection (I)(1), above, or any exhibit or
schedule thereto.


VI.  COVENANTS.

   (A)  Financial Covenants.  The Borrower agrees that so long
as the Bank is committed to make Advances or any amount payable
under either Note or any other Loan Document remains unpaid:

    (1)  Certain Definitions.  As used in this paragraph
(1) and hereafter in this Agreement, the following terms have the
following meanings:

     "Adjusted Debt" means, as of any date, the result
derived by subtracting the outstanding principal balance of the
Borrower's $254,629.00 Convertible Note and its $260,000.00
Convertible Note, each payable to Six Nations, Inc. and dated
May 12, 1999, from the Borrower's total Debt.

     "Adjusted Net Worth" means, as of any date, the sum of
the Borrower's Net Worth and its Subordinated Debt.

other person in respect of amounts paid under a letter of credit
or similar instrument, (vii) all obligations of others secured by
a Lien on any asset of such person, whether or not such
obligation is assumed by such person and (viii) all obligations

without limiting the generality of the foregoing, any obligation,

its expense, execute, deliver, file or record such financing
statements pursuant to the UCC, applications for certificates of

exercise and enforce any of its rights, powers and remedies
hereunder, including, without limitation, its right to take
possession of the Collateral, and will use its best efforts to
obtain such waivers from landlords and mortgagees as the Bank may
request.

     (c)  To the fullest extent permitted by law, the
Borrower authorizes the Bank to sign and file financing and
continuation statements and amendments thereto with respect to
the Collateral without its signature thereon.

     (3)  Change of Name, Identity or Structure.  The
Borrower will not change its name, identity or structure in any
manner and, except as set forth on Appendix 3 hereto, will not
conduct its business under any trade, assumed or fictitious name
unless it shall have given the Bank at least thirty days' prior
written notice thereof and shall have taken all action (or made
arrangements to take such action substantially simultaneously
with such change if it is impossible to take such action in
advance) necessary or reasonably requested by the Bank to amend
any financing statement or continuation statement relating to the
security interests granted hereby in order to preserve such
security interests and to effectuate or maintain the priority
thereof against all persons.

change, makes all UCC filings required by paragraph (2) of this
subsection (B), and takes all other action necessary or that the
Bank may reasonably request to preserve, perfect, confirm and
protect the security interests granted hereby.  The Borrower will
in no event change the location of any Collateral if such change
would cause the security interest granted hereby in such
Collateral to lapse or cease to be perfected.  The Borrower will
at all times maintain its chief executive office within one of
the forty-eight contiguous states in which Article 9 of the UCC
is in effect.

     (5)  Fixtures.  The Borrower will not permit any

the Bank all instruments and documents, including, without
limitation, waivers and subordination agreements by any landlords
and mortgagees, and filed all financing statements necessary or

including, without limitation, a record of all payments received
and all credits granted with respect to the Collateral and all of
its other dealings with the Collateral.  The Borrower will mark
its books and records pertaining to the Collateral to evidence
this Agreement and the security interests granted hereby.  For
the Bank's further security, the Borrower agrees that the Bank
shall have a special property interest in all of the Borrower's
books and records pertaining to the Collateral and the Borrower
shall deliver and turn over any such books and records to the
Bank or to its representatives at any time on demand of the Bank.

     (7)  Compliance with Laws, etc.  The Borrower will
comply, in all material respects, with all acts, rules,
regulations, orders, decrees and directions of any Government
applicable to the Collateral or any part thereof or to the
operation of the Borrower's business except to the extent that
the failure to comply would not have a material adverse effect on
the financial or other condition of the Borrower; provided,
however, that the Borrower may contest any act, regulation,
order, decree or direction in any reasonable manner which shall
not in the sole opinion of the Bank adversely affect the Bank's
rights or the first priority of its security interest in the
Collateral.
<PAGE>
     (8)  Payment of Taxes, etc.  The Borrower will pay
promptly when due, all Taxes, assessments and governmental
charges or levies imposed upon the Collateral or in respect of

such charge is adequately reserved against in accordance with
GAAP.

security interest, encumbrance, or claim in or to the Collateral
other than the security interests created hereunder.

     (11)  Limitations on Modifications of Receivables and
Other Intangibles; No Waivers or Extensions.  The Borrower will
not (a) amend, modify, terminate or waive any provision of any
material Receivable or Other Intangible in any manner which might
have a materially adverse effect on the value of such Receivable
or Other Intangible as Collateral, (b) fail to exercise promptly
and diligently each and every material right which it may have
under each Receivable and Other Intangible or (c) fail to deliver
to the Bank a copy of each material demand, notice or document
received by it relating in any way to any Receivable or Other
Intangible.  The Borrower will not, without the Bank's prior
written consent, grant any extension of the time of payment of
any Receivable or amounts due under any material Other
Intangible, compromise, or settle the same for less than the full
amount thereof, release, wholly or partly, any person liable for
the payment thereof or allow any credit or discount whatsoever
thereon other than trade discounts granted in the normal course
of business, except such as in the reasonable judgment of the
Borrower are advisable to enhance the collectability thereof.

     (12)  Maintenance of Insurance.  The Borrower will
maintain with financially sound insurance companies licensed to
do business where the Borrower is located insurance policies (a)
insuring the Inventory and Equipment against loss by fire,
explosion, theft and such other casualties as are usually insured
against by companies engaged in the same or similar business for
an amount satisfactory to the Bank and (b) insuring the Borrower
and the Bank against liability for personal injury arising from,
and property damage relating to, such Inventory and Equipment,
such policies to be in such form and to cover such amounts as may
be satisfactory to the Bank, with losses payable to the Borrower
and the Bank as their respective interests may appear.  The
Borrower shall, if so requested by the Bank, deliver to the Bank
as often as the Bank may reasonably request a report of the
Borrower or, if requested by the Bank, of an insurance broker
satisfactory to the Bank of the insurance on the Inventory and
<PAGE>
Equipment.  All insurance with respect to the Inventory and the
Equipment shall (w) contain a standard mortgagee clause in favor
of the Bank, (x) provide that any loss shall be payable in
accordance with the terms thereof notwithstanding any act of the
Borrower which might otherwise result in forfeiture of such
insurance and that the insurer waives all rights of set-off,
counterclaim, deduction or subrogation against the Borrower, (y)
provide that no cancellation, reduction in amount or change in
coverage therefor shall be effective until at least 30 days after
receipt by the Bank of written notice thereof and (z) provide
that the Bank may, but shall not be obligated to, pay premiums in
respect thereof.

     (13)  Limitations on Dispositions of Collateral. The
Borrower will not directly or indirectly (through the sale of
stock, merger or otherwise) without the prior written consent of
the Bank sell, transfer, lease or otherwise dispose of any of the
Collateral, or attempt, offer or contract to do so except for (a)
sales of Inventory in the ordinary course of its business for
fair value in arm's-length transactions and (b) so long as no
Default has occurred and is continuing, dispositions in a
commercially reasonable manner of Equipment which has become
redundant, worn out or obsolete or which should be replaced so as
to improve productivity, so long as the proceeds of any such
disposition are (i) used to acquire replacement equipment which
has comparable or better utility and equivalent or better value
and which is subject to a first priority security interest in
favor of the Bank therein, except as permitted by paragraph (9)
of this subsection (B), and except for Permitted Liens, or (ii)
applied to repay the Obligations.  The inclusion of Proceeds of
the Collateral under the security interests granted hereby shall
not be deemed a consent by the Bank to any sale or disposition of
any Collateral other than as permitted by this paragraph (13).

     (14)  Further Identification of Collateral.  The
Borrower will furnish to the Bank from time to time statements
and schedules further identifying and describing the Collateral
and such other reports in connection with the Collateral as the
Bank may reasonably request.

promptly and in reasonable detail (a) of any Lien, security
interest, encumbrance or claim made or asserted against any of
the Collateral, (b) of any material change in the composition of
the Collateral, and (c) of the occurrence of any other event
which would have a material effect on the aggregate value of the
Collateral or on the security interests granted to the Bank in
this Agreement.
<PAGE>
     (16)  Right of Inspection.  The Bank shall at all times
have full and free access during normal business hours to all the

with officers, employees and public accountants of the Borrower
as the Bank may deem necessary, and the Borrower agrees to render
to the Bank, at the Borrower's cost and expense, such clerical
and other assistance as may be reasonably requested with regard
thereto.  The Bank and its representatives shall at all times
also have the right to enter into and upon any premises where any
of the Inventory or Equipment is located for the purpose of
inspecting the same, observing its use or protecting interests of
the Bank therein.

     (17)  Maintenance of Equipment.  The Borrower will, at
its expense, generally maintain the Equipment in good operating
condition, ordinary wear and tear excepted.

     (18)  Reimbursement Obligation.  Should the Borrower
fail to comply with the provisions of either Note, this
Agreement, any other Loan Document to which it is a party or any
other agreement relating to the Collateral such that the value of
any Collateral or the validity, perfection, rank or value of any
security interest granted to the Bank hereunder or thereunder is
thereby diminished or potentially diminished or put at risk (as
reasonably determined by the Bank), the Bank on behalf of the
Borrower may, but shall not be required to, effect such
compliance on behalf of the Borrower, and the Borrower shall
reimburse the Bank for the cost thereof on demand, and interest
shall accrue on such reimbursement obligation from the date the
relevant costs are incurred until reimbursement thereof in full

payment or provide compensation (including without limitation the
establishment of customary employee benefit plans) for personal
services rendered by employees and other persons on terms fair
and reasonable in light of the circumstances under which such

Nothing in this paragraph (10) shall prohibit the Borrower or
such Subsidiary from making sales to or purchases from any
Affiliate and, in connection therewith, extending credit or
making payments, or from making payments for services rendered by
any Affiliate, if such sales or purchases are made or such
services are rendered in the ordinary course of business and on
terms and conditions at least as favorable to the Borrower or
such Subsidiary as the terms and conditions which would apply in
a similar transaction with a person not an Affiliate, or prohibit
the Borrower or such Subsidiary from participating in, or
effecting any transaction in connection with, any joint
enterprise or other joint arrangement with any Affiliate if the
Borrower or such Subsidiary participates in the ordinary course
of its business and on a basis no less advantageous than on the
basis on which such Affiliate participates.

     (11)  Restricted Payments.  The Borrower will not, and

right to acquire shares of the Borrower's or such Subsidiary's
capital stock.

      (12)  Investments.  The Borrower will not make or

preserve and maintain, and shall cause each of its Subsidiaries
to preserve and maintain, its senior management as currently
constituted.

     (D)  Independence of Covenants.  All covenants contained in
this Agreement shall be given independent effect so that if a
particular action or condition is not permitted by any of such
covenants, the fact that such action or condition would be
permitted by an exception to, or otherwise be within the
limitations of another covenant shall not avoid the occurrence of
a Default if such action is taken or condition exists.

VII.  REMEDIES.

     (A)  UCC Rights.  If any Default shall have occurred, the
Bank may in addition to all other rights and remedies granted to
it in this Agreement, either Note, any and all other Loan
Documents and in any other instrument or agreement securing,
evidencing or relating to the Obligations, exercise all rights
and remedies of a secured party under the UCC and all other
rights available to the Bank at law or in equity.

     (B)  Payments on Collateral.  Without limiting the rights of
the Bank under any other provision of this Agreement, if a
Default shall occur and be continuing:

     (1)  all payments received by the Borrower under or in
connection with any of the Collateral and not subject to the
Lockbox Agreement shall be held by the Borrower in trust for the
Bank, shall be segregated from other funds of the Borrower and
shall forthwith upon receipt by the Borrower be turned over to
the Bank, in the same form as received by the Borrower (duly
indorsed by the Borrower to the Bank, if required to permit
collection thereof by the Bank); and

     (2)  all such payments received by the Bank (whether
from the Borrower or otherwise) may, in the sole discretion of
the Bank, be held by the Bank as collateral security for, and
then or at any time thereafter applied in whole or in part by the
Bank to the payment of the expenses and Obligations as set forth
in subsection (J), below.
<PAGE> (C)  Possession of Collateral.  In furtherance of the
foregoing, the Borrower expressly agrees that, if a Default shall
occur and be continuing, the Bank may (i) by judicial powers, or
without judicial process if it can be done without breach of the
peace, enter any premises where any of such Collateral is or may
be located, and without charge or liability to the Bank seize and
remove such Collateral from such premises and (ii) have access to
and use of the Borrower's books and records relating to such
Collateral.

     (D)  Sale of Collateral.

     (1)  The Borrower expressly agrees that if a
Default shall occur and be continuing, the Bank, without demand
of performance or other demand or notice of any kind (except the
notice specified below of the time and place of any public or
private sale) to the Borrower or any other person (all of which
demands and notices are hereby waived by the Borrower), may
forthwith collect, receive, appropriate and realize upon the
Collateral and forthwith sell, lease, assign, give an option or
options to purchase or otherwise dispose of and deliver the
Collateral or any part thereof (or contract to do so) in one or
more parcels at public or private sale, at any exchange, broker's
board or at any office of the Bank or elsewhere in such manner as
is commercially reasonable and as the Bank may deem best, for
cash or on credit or for future delivery without assumption of
any credit risk.  The Bank shall have the right upon any such
public sale, and, to the extent permitted by law, upon any such
private sale, to purchase the whole or any part of the Collateral
so sold.  The Borrower further agrees, at the Bank's request, to
assemble the Collateral, and to make it available to the Bank at
places which the Bank may reasonably select.  To the extent
permitted by applicable law, the Borrower waives all claims,
damages and demands against the Bank arising out of the
foreclosure, repossession, retention or sale of the Collateral.

     (2)  Unless the Collateral threatens to decline
speedily in value or is of a type customarily sold in a
recognized market, the Bank shall give the Borrower five (5)
days' written notice of its intention to make any such public or
private sale or sale at a broker's board or on a securities
exchange.  Such notice shall (a) in the case of a public sale,
state the time and place fixed for such sale, (b) in the case of
a sale at a broker's board or on a securities exchange,  state
the board or exchange at which such sale is to be made and the
day on which the Collateral, or any portion thereof being sold,
will first be offered for sale and (c) in the case of a private
sale, state the day after which such sale may be consummated.
The Bank shall not be required or obligated to make any such sale
pursuant to any such notice.  The Bank may adjourn any public or
private sale or cause the same to be adjourned from time to time
by announcement at the time and place fixed for the sale, and
such sale may be made at any time or place to which the same may
be so adjourned.  In the case of any sale of all or any part of
the Collateral for credit or for future delivery, the Collateral
so sold may be retained by the Bank until the selling price is
paid by the purchaser thereof, but the Bank shall not incur any
liability in case of failure of such purchaser to pay for the
Collateral so sold and, in the case of such failure, such
Collateral may again be sold upon like notice.
<PAGE>
     (E)  Rights of Purchasers.  Upon any sale of the Collateral
(whether public or private), the Bank shall have the right to
deliver, assign and transfer to the purchaser thereof the
Collateral so sold.  Each purchaser (including the Bank) at any
such sale shall hold the Collateral so sold free from any claim
or right of whatever kind, including any equity or right of
redemption of the Borrower, and the Borrower, to the extent
permitted by law, hereby specifically waives all rights of
redemption and any right to a judicial or other stay or approval
which it has or may have under any law now existing or hereafter
adopted.

     (F)  Additional Rights of the Bank.

     (1)  The Bank shall have the right and power to
institute and maintain such suits and proceedings as it may deem
appropriate to protect and enforce the rights vested in it by
this Agreement and may proceed by suit or suits at law or in
equity to enforce such rights and to foreclose upon and sell the
Collateral or any part thereof pursuant to the judgment or decree
of a court of competent jurisdiction.

     (2)  The Bank shall, to the extent permitted by
law and without regard to the solvency or insolvency at the time
of any Person then liable for the payment of any of the
Obligations or the then value of the Collateral, and without
requiring any bond from any party to such proceedings, be
entitled to the appointment of a special receiver or receivers
(who may be the Bank) for the Collateral or any part thereof and
for the rents, issues, tolls, profits, royalties, revenues and
other income therefrom, which receiver shall have such powers as
the court making such appointment shall confer, and to the entry
of an order directing that the rents, issues, tolls, profits,
royalties, revenues and other income of the property constituting
the whole or any part of the Collateral be segregated,
sequestered and impounded for the benefit of the Bank, and the
Borrower irrevocably consents to the appointment of such receiver
or receivers and to the entry of such order.

     (G)  Remedies Not Exclusive.

     (1)  No remedy conferred upon or reserved to the
Bank in this Agreement is intended to be exclusive of any other
remedy or remedies, but every such remedy shall be cumulative and
shall be in addition to every other remedy conferred herein or
now or hereafter existing at law, in equity or by statute.

     (2)  If the Bank shall have proceeded to enforce any
right, remedy or power under this Agreement and the proceeding
for the enforcement thereof shall have been discontinued or
abandoned for any reason or shall have been determined adversely
to the Bank, the Borrower and the Bank shall, subject to any
determination in such proceeding, severally and respectively be
restored to their former positions and rights under this
Agreement, and thereafter all rights, remedies and powers of the
Bank shall continue as though no such proceedings had been taken.
<PAGE>
     (3)  All rights of action under this Agreement may be
enforced by the Bank without the possession of any instrument
evidencing any Obligation or the production thereof at any trial
or other proceeding relative thereto, and any suit or proceeding
instituted by the Bank shall be brought in its name and any
judgment shall be held as part of the Collateral.

    (H)  Waiver and Estoppel.

     (1)  The Borrower, to the extent it may lawfully
do so, agrees that it will not at any time in any manner
whatsoever claim or take the benefit or advantage of any
appraisement, valuation, stay, extension, moratorium, turnover or
redemption law, or any law now or hereafter in force permitting
it to direct the order in which the Collateral shall be sold
which may delay, prevent or otherwise affect the performance or
enforcement of this Agreement and the Borrower hereby waives the
benefits or advantage of all such laws, and covenants that it
will not hinder, delay or impede the execution of any power
granted to the Bank in this Agreement but will permit the
execution of every such power as though no such law were in
force; provided that nothing contained in this subsection (H)
shall be construed as a waiver of any rights of the Borrower
under any applicable federal bankruptcy law.

     (2)  The Borrower, to the extent it may lawfully do so,
on behalf of itself and all who may claim through or under it,
including without limitation any and all subsequent creditors,
vendees, assignees and lienors, waives and releases all rights to
demand or to have any marshalling of the Collateral upon any
sale, whether made under any power of sale granted herein or
pursuant to judicial proceedings or upon any foreclosure or any
enforcement of this Agreement and consents and agrees that all
the Collateral may at any such sale be offered and sold as an
entirety.

     (3)   The Borrower, to the extent it may lawfully do so,
waives presentment, demand, protest and any notice of any kind
(except notices explicitly required hereunder) in connection with
this Agreement and any action taken by the Bank with respect to
the Collateral.

     (I)  Power of Attorney.  The Borrower hereby irrevocably
constitutes and appoints the Bank, with full power of
substitution, as its true and lawful attorney-in-fact with full
irrevocable power and authority in the place and stead of the
Borrower and in the name of the Borrower or in its own name, from
time to time in the Bank's reasonable discretion for the purpose
of carrying out the terms of this Agreement, to take any and all
appropriate action and to execute any and all documents and
instruments which may be necessary or desirable to accomplish the
purposes of this Agreement and, without limiting the generality
of the foregoing, hereby gives the Bank the power and right, on
behalf of the Borrower, without notice to or assent by the
Borrower to do the following:
<PAGE>
     (1)  to pay or discharge Taxes, Liens, security
interests or other encumbrances levied or placed on or threatened
against the Collateral;

     (2)  to effect any repairs or any insurance called for
by the terms of this Agreement and to pay all or any part of the
premiums therefor and the costs thereof; and

     (3)  upon the occurrence and continuance of any Default
and otherwise to the extent provided in this Agreement, (a) to
direct any party liable for any payment under any of the
Collateral to make payment of any and all moneys due and to come
due thereunder directly to the Bank or as the Bank shall direct;
(b) to receive payment of and receipt for any and all moneys,
claims and other amounts due and to become due at any time in
respect of or arising out of any Collateral; (c) to sign and
indorse any invoices, freight or express bills, bills of lading,
storage or warehouse receipts, drafts against debtors,
assignments, verifications and notices in connection with
accounts and other documents relating to the Collateral; (d) to
commence and prosecute any suits, actions or proceedings at law
or in equity in any court of competent jurisdiction to collect
the Collateral or any part thereof and to enforce any other right
in respect of any Collateral; (e) to defend any suit, action or
proceeding brought against the Borrower with respect to any
Collateral; (f) to settle, compromise and adjust any suit, action
or proceeding described above and, in connection therewith, to
give such discharges or releases as the Bank may deem
appropriate; (g) to assign any patent or trademark (along with
the goodwill of the business to which such trademark pertains),
for such term or terms, on such conditions, and in such manner,
as the Bank shall in its sole discretion determine; and (h)
generally to sell, transfer, pledge, make any agreement with
respect to or otherwise deal with any of the Collateral as fully
and completely as though the Bank were the absolute owner thereof
for all purposes, and to do, at the Bank's option and the
Borrower's expense, at any time, or from time to time, all acts
and things which the Bank deems necessary to protect, preserve or
realize upon the Collateral and the Bank's security interest
therein, in order to effect the intent of this Agreement, all as
fully and effectively as the Borrower might do.

     The Borrower hereby ratifies all that said attorney shall
lawfully do or cause to be done by virtue hereof.  This power of
attorney is a power coupled with an interest and shall be
irrevocable.
<PAGE>
     (J)  Application of Proceeds.  The Bank shall retain the net
proceeds of any collection, recovery, receipt, appropriation,
realization or sale of the Collateral and, after deducting all
reasonable costs and expenses of every kind incurred therein or
incidental to the care and safekeeping of any or all of the
Collateral or in any way relating to the rights of the Bank
hereunder, including reasonable attorneys' fees and legal
expenses, apply such net proceeds to the payment in whole or in
part of the Obligations in such order as the Bank may elect, the
Borrower remaining liable for any amount remaining unpaid (and
any attorneys' fees paid by the Bank in collecting such
deficiency) after such application.  Only after applying such net
proceeds and after the payment by the Bank of any other amount
required by any provision of law, including Section 9-504(1)(c)
of the UCC, need the Bank account for the surplus, if any, to the
Borrower or to whomsoever may be lawfully entitled to the same.

VIII.  MISCELLANEOUS.

     (B)  No Waivers.  No failure on the part of the Bank to
exercise, no course of dealing with respect to, and no delay in
exercising any right, power or privilege under this Agreement or
any document or agreement contemplated hereby shall operate as a
waiver thereof nor shall any single or partial exercise of any
such right, power or privilege preclude any other or further
exercise thereof or the exercise of any other right, power or
privilege.

     (C)  Compensation and Expenses of the Bank.  The Borrower
shall pay to the Bank from time to time upon demand, all of the
fees, costs and expenses incurred by the Bank (including, without
limitation, the reasonable fees and disbursements of counsel and
any amounts payable by the Bank to any of its agents, whether on
account of fees, indemnities or otherwise) (1) arising in
connection with the preparation, administration, modification,
amendment, waiver or termination of this Agreement or any
document or agreement contemplated hereby or any consent or
waiver hereunder or thereunder or (2) incurred in connection with

and to the Collateral.
<PAGE>

hereafter indemnify, hold harmless and, on demand, reimburse the
Bank, its subsidiaries, affiliates, successors, assigns,
officers, directors, employees and agents, and their respective
heirs, executors, administrators, successors and assigns (all of
the foregoing parties, including, but not limited to, the Bank,
being hereinafter collectively referred to as the "Indemnitees"
and individually as an "Indemnitee") from, against and for any
and all liabilities, obligations, claims, damages, actions,
penalties, causes of action, losses, judgments, suits, costs,
expenses and disbursements, including, without limitation,
attorney's fees (any and all of the foregoing being hereinafter
collectively referred to as the "Liabilities" and individually as
a "Liability") which the Indemnitees, or any of them, might be or
become subjected, by reason of, or arising out of the
preparation, execution, delivery, modification, administration or
enforcement of, or performance of the Bank's rights under, this
Agreement or any other document, instrument or agreement
contemplated hereby or executed in connection herewith; provided
that the Borrower shall not be liable to any Indemnitee for any
Liability caused solely by the gross negligence or willful
misconduct of such Indemnitee.  In no event shall any Indemnitee,
as a condition to enforcing its rights under this subsection (D)
or otherwise, be obligated to make a claim against any other
person (including, without limitation, the Bank) to enforce its
rights under this subsection (D).

     (E)  Amendments, Supplements and Waivers.  The parties
hereto may, from time to time, enter into written agreements
supplemental hereto for the purpose of adding any provisions to
this Agreement, waiving any provisions hereof or changing in any
manner the rights of the parties.

     (F)  Successors and Assigns.  This Agreement shall be
binding upon and inure to the benefit of each of the parties
hereto and shall inure to the benefit of the Bank's successors
and assigns.  Nothing herein is intended or shall be construed to
give any other person any right, remedy or claim under, to or in
respect of this Agreement or any Collateral.

     (G)  Waiver of Jury Trial; Submission to Jurisdiction.  THE
BORROWER IRREVOCABLY AND UNCONDITIONALLY WAIVES ALL RIGHT TO
TRIAL BY JURY IN ANY SUIT, ACTION, PROCEEDING, OR COUNTERCLAIM
ARISING OUT OF OR RELATED TO THIS AGREEMENT, EITHER NOTE OR ANY
OTHER LOAN DOCUMENT OR ANY OF THE TRANSACTIONS CONTEMPLATED
HEREBY OR THEREBY.  Borrower irrevocably (i) submits to the
jurisdiction of any Virginia state court or federal court sitting
in the state of Virginia with respect to any suit, action, or
proceeding relating to this Agreement, either Note, or any other
Loan Document, (ii) waives any objection which it may now or
hereafter have to the laying of venue of any such suit, action,
or proceeding brought in any such court has been brought in an
inconvenient forum, and (iii) waives the right to object that any
such court does not have jurisdiction over it.  Nothing in this
paragraph shall affect the Bank's right to serve process in any
other manner permitted by law or to bring proceedings against the
Borrower in any other court having jurisdiction.
<PAGE>
     (H)  Termination; Survival.  This Agreement shall terminate
when the security interests granted hereunder have terminated and
the Collateral has been released as provided in Section III(F);
provided that the obligations of the Borrower under any of
Section VI(B)(18), VIII(C) and VIII(D) shall survive any such
termination.

     (I)  Entire Agreement.  This Agreement, the Lockbox
Agreement, the Subordination Agreements, the Notes and the other
Loan Documents set forth the entire agreement of the parties with
respect to the subject matter hereof and thereof and supersede
all previous understandings, written or oral, in respect thereof.

     (J)  Limitation of Law; Severability.

     (1)  All rights, remedies and powers provided in this
Agreement may be exercised only to the extent that the exercise
thereof does not violate any applicable provision of law, and all
the provisions of this Agreement are intended to be subject to
all applicable mandatory provisions of law which may be
controlling and to be limited to the extent necessary so that
they will not render this Agreement invalid, unenforceable in
whole or in part, or not entitled to be recorded, registered or
filed under the provisions of any applicable law.

     (2)  If any provision hereof is invalid and
unenforceable in any jurisdiction, then, to the fullest extent
permitted by law, (a) the other provisions hereof shall remain in
full force and effect in such jurisdiction and shall be liberally
construed in order to carry out the intentions of the parties
hereto as nearly as may be possible; and (b) the invalidity or
unenforceability of any provision hereof in any jurisdiction
shall not affect the validity or enforceability of such
provisions in any other jurisdiction.

     (K)  Governing Law.  This Agreement shall be governed by and
construed in accordance with the laws of the Commonwealth of
Virginia.

and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, each of the
undersigned jointly and severally (hereinafter individually and
collectively called the "Guarantors"), hereby unconditionally
guaranty to the Bank the full and prompt payment at maturity,
including accelerated or extended maturity, of all Obligations,
as hereinafter defined, of the Debtor to the Bank.  The term
"Obligations" means all indebtedness, obligations and liabilities
of the Debtor to the Bank now existing or hereafter created or
arising, whether direct or indirect, absolute or contingent,
joint or several, secured or unsecured, liquidated or
unliquidated, and evidenced by that certain Commercial Note dated
June 29, 1999 from the Debtor payable to the order of the Bank in
the original amount of $1,500,000.00, and all renewals,
increases, extensions, and modifications thereof and
substitutions therefor.

The Bank may at any time and from time to time, without
the consent of or notice to the Guarantors, without incurring
liability to the Guarantors, and without affecting, impairing or
releasing the obligations of the Guarantors hereunder, renew,
extend, change the manner, time, place, and terms of payment,
grant indulgences in connection with, settle, compromise, sell,
exchange, substitute, release, surrender, subordinate, or
exercise or refrain from exercising any rights with respect to,
any of the Obligations, any security therefor, the obligation of
any of the Guarantors hereunder or any other party primarily or
secondarily liable for any of the Obligations.
<PAGE>
The liability of the Guarantors shall not be affected,
impaired or released by (i) any failure, neglect or omission by
the Bank to realize upon or collect any of the Obligations, any
obligation hereunder, or any security for or guaranty of the
Obligations or any obligation hereunder, or to exercise any
remedies of setoff or otherwise that it may have with respect to
property of the Debtor possessed by the Bank, (ii) any defense
the Debtor or any other party primarily or secondarily liable for
any of the Obligations might have to the payment of the
Obligations, (iii) any determination that any lien taken, or
attempted to be taken, by the Bank to secure the Obligations is
invalid or unperfected, (iv) any determination that any party
executing any evidence of any of the Obligations on behalf of the
Debtor was without power or authority to do so or that for any
other reason the Obligations, any security therefor, or any other
guaranty thereof, are invalid or unenforceable, or (v) any
defenses the Debtor may have or assert to the Obligations.  It is
understood that nothing shall discharge or satisfy the
Guarantors' liability hereunder except the full performance and
payment of all Obligations with interest and expenses, or the
Bank's written release of the Guarantors' liability.

The Guarantors' liability hereunder shall not be
affected, impaired or released by the filing of a petition by or
against the Debtor under the provisions of any bankruptcy,
reorganization, arrangement, insolvency, liquidation or similar
law for relief of debtors, and upon the filing of such petition,
for the purpose of this Guaranty, all Obligations, at the option
of the Bank, shall be immediately due and payable.

The Guarantors represent and covenant that they are and
shall remain independently informed of the financial condition of
the Debtor and all other circumstances which bear on the risk of
non-payment of the Obligations.  The Guarantors waive any right
to require the Bank to disclose to them any information the Bank
has or may have in the future concerning such condition or
circumstances.

The Guarantors subordinate all obligations of the
Debtor owing to them or any of them, whether now existing or
hereafter arising, to all Obligations of the Debtor to the Bank.

The Guarantors unconditionally waive any right they may
have to be subrogated to the rights of the Bank against the
Debtor with respect to any payment by the Guarantors hereunder,
and further unconditionally waive any right they may have of
reimbursement or indemnification from the Debtor with respect to
any such payment.

If at any time any payment by the Debtor of any
Obligation is rescinded or must otherwise be restored or returned
upon the insolvency, bankruptcy, dissolution, liquidation or
reorganization of the Debtor or upon or as a result of the
appointment of a receiver, intervener or conservator of, or
trustee or similar officer for, the Debtor or any substantial
part of its property or otherwise, the Guarantors' obligations
hereunder with respect to such payment shall be reinstated as
though such payment had been due but not made at such time.
<PAGE>
The Guarantors waive (i) notice of acceptance of this
Guaranty, (ii) notice of the existence or creation of the
Obligations, (iii) presentment and demand for payment of any of
the Obligations, (iv) protest and notice of dishonor and protest
and any other notice to the Guarantors or to any other party with
respect to the Obligations, and (v) the benefit of their
homestead exemptions and any other exemptions with respect to the
Obligations.

This is a guaranty of payment and not of collection.
The Guarantors waive any right, including without limitation any
right arising from Section 49-25 or 49-26 of the Code of
Virginia, to require that the Bank bring action against the
Debtor or any other party or to require that the Bank resort to
any security or to any balance of any deposit account or credit
on the books of the Bank in favor of Debtor or any other party.

All payments, whether voluntary or involuntary,
received by the Bank from the Debtor, Guarantors, or any other
source, including amounts realized from security and deposit
account balances, may be applied by the Bank to any of the
Obligations, or any other obligations of the Guarantors or any
other obligor, in whatever order the Bank elects.

The Bank may, without notice to or consent of the
Guarantors, assign or transfer all or any part of the Obliga-
tions, and this Guaranty will inure to the benefit of the Bank's
assignee or transferee to the extent of such assignment or trans-
fer; provided, however, that the Bank shall continue to have an
unimpaired right, superior to that of any such assignee or trans-
feree, to enforce this Guaranty as to that part of the Obliga-
tions the Bank has not assigned or transferred.

The Bank will have the right, in addition to any
remedies permitted by law (including, without limitation, other
rights of set-off), to set off the amount now or hereafter due
under this Guaranty against any and all accounts, credits, money,
securities, or other property now or hereafter on deposit with,
held by, or in possession of the Bank to the credit of or for the
account of each of the Guarantors, without notice to or consent
by the Guarantors.  In addition to the right of set-off, to
secure the payment of their obligations under this Guaranty, each
of the Guarantors hereby assigns and grants to the Bank a
security interest in all accounts, credit, money, securities, or
other property now or hereafter on deposit with, held by, or in
the possession of the Bank to the credit of or for the account of
such Guarantor.

The Guarantors shall pay to the Bank on demand all
costs incurred by the Bank, and reasonable attorneys' fees, in
the collection or enforcement of this Guaranty, whether or not
suit is brought.

	The Guarantors agree to furnish the Bank, in form
acceptable to the Bank, (i) a signed, current personal financial
statement and personal federal income tax return annually, within
30 days after the filing of the latter, and (ii) such other
financial information and data as the Bank may from time to time
request.
<PAGE>
THE GUARANTORS IRREVOCABLY AND UNCONDITIONALLY WAIVE
ANY RIGHT THEY MAY HAVE TO TRIAL BY JURY IN ANY SUIT, ACTION,
PROCEEDING, OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS
GUARANTY, WHETHER SUCH SUIT, ACTION, PROCEEDING, OR COUNTERCLAIM
IS INSTITUTED BY THE BANK, THE GUARANTORS OR ANY OTHER PARTY.

The Guarantors irrevocably (i) submit to the juris-
diction of any Virginia state court or federal court sitting in
the state of Virginia with respect to any suit, action, or
proceeding relating to this Guaranty, (ii) waive any objection
which the Guarantors may now or hereafter have to the laying of
venue of any such suit, action, or proceeding brought in any such
court and any claim that any such suit, action or proceeding
brought in any such court has been brought in an inconvenient
forum, (iii) waive the right to object that any such court does
not have jurisdiction over the Guarantors, and (iv) consent to
the service of process in any such suit, action, or proceeding by
the mailing of copies of such process to the Guarantors by
certified mail at the Guarantors' addresses indicated in this
Guaranty or at such other addresses of which the Bank shall have
received notice.  Nothing in this paragraph shall affect the
Bank's right to serve process in any other manner permitted by
law or to bring proceedings against the Guarantors in any other
court having jurisdiction.

The rights and remedies of the Bank under this Guaranty
and applicable law shall be cumulative and concurrent and the
exercise of any one or more of them shall not preclude the simul-
taneous or later exercise by the Bank of any or all such other
rights or remedies.  In the event any provision of this Guaranty
is held to be invalid, illegal, or unenforceable for any reason,
then such provision only shall be deemed null and void and shall
not affect any other provisions of this Guaranty, which shall
remain effective.  No modification or waiver of any provision of
this Guaranty shall be effective unless it is in writing and
signed by the Bank, and any such waiver shall be effective only
in the specific instance and for the specific purpose for which
it is given.  The failure of the Bank to exercise any option,
right or remedy, in any one or more instances, or the acceptance
by the Bank of partial payments or partial performance, shall not
constitute a waiver of the right to exercise any option, right or
remedy at any time.  The nouns, pronouns and verbs used in this
Guaranty shall be construed as being of such number and gender as
the context may require.

This Guaranty shall be governed by and construed in
accordance with the laws of Virginia.
