      NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS 
                         (Unaudited)

Note 1.   General

     The accompanying condensed consolidated financial statements
of Telos Corporation ("Telos") (formerly C3, Inc.) and its wholly
owned  subsidiaries, Telos Corporation (California), Telos  Field
Engineering  Inc.,  and  Telos International  (collectively,  the
"Company") have been prepared without audit.  Certain information
and   note   disclosures  normally  included  in  the   financial
statements  presented  in  accordance  with  generally   accepted
accounting  principles  have  been  condensed  or  omitted.   The
Company  believes the disclosures made are adequate to  make  the
information  presented consistent with past  practices.  However,
these condensed consolidated financial statements should be  read
in  conjunction  with the consolidated financial  statements  and
notes thereto included in the Company's annual report on Form 10-
K for the fiscal year ended December 31, 1994.
     
     In  the  opinion of the Company, the accompanying  condensed
consolidated  financial statements reflect  all  adjustments  and
reclassifications   (which   include   only   normal    recurring
adjustments)  necessary to present fairly the financial  position
of the Company as of June 30, 1995 and December 31, 1994, and the
results  of its operations and its cash flows for the six  months
ended   June  30,  1995  and  1994.   Interim  results  are   not
necessarily indicative of fiscal year performance because of  the
impact of seasonal and short-term variations.
     
     Included  in Systems and Services sales for the  six  months
ended June 30, 1995 are Product sales of $23,563,000.
     
     Certain reclassifications have been made to the prior year's 
financial statements to conform to the classifications used in the
current period.

Note 3.   Debt Obligations

Senior Credit Facility

      On April 17, 1995, the Company refinanced its senior credit
facility ("Facility") with its existing lender.  The new Facility
remains a $45 million commitment with a maturity date of July  1,
1996.  Other terms and conditions of the Facility are similar  to
the Company's previous Facility except that certain financial and
non  financial covenants have been amended.  In 1995, certain  of
the  Company's shareholders have made deposits with the Company's
bank  to  provide the Company with increased borrowing capability
under   its  Facility.   Total  shareholder  deposits  with   the
Company's   bank   total  $7  million.   The  Company   and   its
shareholders have agreed to negotiate appropriate return  to  the
shareholders  for  this provision of capital.  Such  negotiations
are  in process.  The Company currently anticipates that the form
of  such  return  will  be  long term  instruments  substantially
similar to the ones to be issued in exchange for the subordinated
bridge  notes.  See Senior Subordinated Notes, Series B described
below.

Senior Subordinated Note, Series A

      At  June  30, 1995, the Company had $675,000 of the  senior
subordinated  notes, Series A, outstanding  with  Mr.  John  R.C.
Porter  ("Porter"),  the Company's majority  common  shareholder.
The  Company was not in compliance with the financial maintenance
covenants of the senior subordinated notes, Series A as  of  June
30, 1995.  Porter has agreed to waive such non compliance.

Senior Subordinated Notes, Series B

      The Company entered into an agreement with Union de Banques
Suisses  (Luxembourg) S. A. ("UBS") on June 8, 1995  whereby  the
Company  paid UBS $5.8 million in outstanding principal, $500,000
of  accrued  interest and $200,000 of legal and  other  fees   in
satisfaction of the claims of UBS with respect to the Series  B-1
and B-2 notes.

     The  funds  to  pay  UBS were provided  by  certain  of  the
Company's common shareholders.  The shareholders have been issued
subordinated bridge notes aggregating approximately $6.5 million.
The  notes  have  a  maturity date of October 1,  1996  and  have
interest  rates  ranging  from 14% to 17  1/2%.   Currently,  the
Company   is  negotiating  terms  for  certain  long  term   debt
instruments  that  will  replace the subordinated  bridge  notes.
While  the  terms have not been finalized, these debt instruments
are  expected  to  bear similar stated interest and  may  contain
certain  substantial  prepayment premiums currently  expected  to
have a value of approximately 13 1/2% per annum which become  due
should specified events happen.

Item 2.  Management's Discussion and Analysis of Financial
         Condition and Results of Operations.

General

     In  the  first  half  of  1995, the Company  had  comparable
revenues  to  the  first  half of 1994, and  increased  operating
profit  as compared to 1994. The higher operating profit  results
from  declines  in  selling, general and administrative  expenses
which  include  a  reduction in rebid  efforts  and  spending  on
product initiatives.
     
     Total backlog from existing contracts was $405 million as of
June  30, 1995, as compared to $328 million at December 31, 1994.
As  of  June 30, 1995, the funded backlog of the Company  totaled
$82  million, a decrease of $11 million from December  31,  1994.
Funded  backlog represents aggregate contract revenues  remaining
to  be  earned by the Company at a given time, but  only  to  the
extent,  in  the  case  of  government  contracts,  funded  by  a
procuring government agency and allotted to the contracts.

Results of Operations
     
     The  condensed consolidated statements of income include the
results  of operations of Telos Corporation and its wholly  owned
subsidiaries   Telos   Corporation  (California),   Telos   Field
Engineering  Inc., and Telos International ("the Company").   The
major  elements  of  the  Company's  operating  expenses   as   a
percentage  of  sales for the three and six month  periods  ended
June 30, 1995 and 1994 are as follows:

Financial Data by Market Segment

      The Company operates in three market segments: systems  and
services  (the "Systems and Services Group"), which  consists  of
systems  integration  and  software services;  computer  hardware
maintenance  (the  "Field  Engineering  Group");  and  consulting
services (the "Consulting Group").

      Sales, gross profit, and gross margin by market segment for
the periods designated below are as follows:


                        Three Months Ended     Six Months Ended

     For  the  three  month  period ended June  30,  1995,  sales
declined  by $1.3 million, or 3.0%, to $41.8 million  from  $43.1
million  for the comparable 1994 period.    The decrease for  the
three  month  period is attributable to the Systems and  Services
Group, which reported a decrease in sales of $1.4 million for the
three  month  period, and to the Field Engineering  Group,  which
reported  a  decrease in sales of $500,000 for  the  three  month
period,  offset by an increase in Consulting Group sales for  the
three  month period of $600,000.  Within the Systems and Services
Group,  certain  of  the Company's software services  groups  had
decreased  sales  of $900,000 in the three month  period  due  to
certain contracts not being renewed during 1995.  The decline  in
sales within the Field Engineering Group of $500,000 in the three
month  period is attributable to reductions in contract  activity
for  the  segment,  and in warranty services related  to  systems
integration  customers.  The Consulting Group sales  increase  of
$600,000  for the three month period is attributable to increased
billable  hours  resulting  from  obtaining  new  customers   and
expanding service to existing customers.
     
     Sales  increased  $1.5 million from $87.1 million  to  $88.6
million for the six months ended June 30, 1995 as compared to the
same  1994  period.   The increase for the six  month  period  is
attributable  to  the Systems and Services Group,  which  had  an
increase of $400,000 for the six month period, and the Consulting
Group,  which  had  a $1.8 million increase  for  the  six  month
period,  offset by a decline in Field Engineering Group sales  of
$700,000 for the six month period.

     For  the  six month period ended June 30, 1995, the majority
of  the increase within the Systems and Services Group is due  to
systems  integration sales, which increased $3.7 million  in  the
first  six  months of 1995 compared to the same period  in  1994.
This  increase  is  attributable to order volume  under  the  INS
contract,  which  was  awarded in  September  1994,  as  well  as
increased  sales  in other business lines of the  division.   The
decrease in sales within the Field Engineering Group for the  six
month  period  of $700,000 is due to the reductions  in  contract
activity  and  the  performance of  warranty  services  discussed
above.   The increase of $1.8 million in sales for the Consulting
Group  for the six month period is the result of the increase  in
billable hours and expansion of services also discussed above.
     
     Cost  of  sales  increased by $700,000  or  1.8%,  to  $35.3
million in the three month period ended June 30, 1995, from $34.6
million  in the comparable 1994 period.  The increase in cost  of
sales  is primarily due to the Field Engineering Group,  with  an
increase in cost of sales for the three month period of $800,000.
The  increase  in  cost of sales within this Group,  despite  its
decrease  in  sales for the three month period  of  $500,000,  is
attributable to certain increased costs at the division's  depots
and  overseas locations.  For the six months ended June 30, 1995,
cost  of  sales increased $2.2 million, or 3.1%, to $73.2 million
from $71.0 million for the same period in 1994.  The increase  is
a result of the increase in sales volume for the six month period.
     
     Gross profit declined $1.9 million in the three month period
to $6.5 million, from $8.4 million in the comparable 1994 period.
For  the six month period, gross profit decreased by $700,000  to
$15.4 million from $16.1 million.  The decline in both periods is
primarily  attributable to the decline in  gross  profit  in  the
Field  Engineering  Group discussed above.   Gross  margins  were
15.6%  and 17.4% for the three and six month periods of  1995  as
compared to 19.6% and 18.6% for the comparable periods of 1994.
     
     Selling,   general,  and  administrative  expense   ("SG&A")
decreased by approximately $2.0 million or 31.4%, to $4.3 million
in the second quarter of 1995 from $6.3 million in the comparable
period  of 1994.  For the six month period of 1995, SG&A declined
$1.3  million to $11.1 million from $12.4 million in  1994.   The
decreases are primarily due to reduced spending by the Company in
certain administrative cost areas and in its bid and proposal and
marketing efforts.   The Company has also reduced its spending on
certain  of  its  product initiatives in 1995.   Also,  the  1994
period included significant costs associated with contract  rebid
activities.    SG&A as a percentage of sales decreased  to  10.4%
for  the second quarter of 1995 from 14.7% in the comparable 1994
period.   SG&A as a percentage of sales for the six month  period
ended June 30, 1995 decreased to 12.5% from 14.3% compared to the
same period in 1994 due to a decrease in SG &A and an increase in
sales.
     
     Goodwill amortization expense was $795,000 and $1.6  million
for  each  of  the three and six month periods, respectively,  in
1995  and 1994, as the Company continues to amortize its goodwill
balance  which resulted primarily from the acquisition  of  Telos
Corporation.

     Operating  income increased by $100,000 to $1.4  million  in
the  three  month period from $1.3 in the comparable 1994  period
and  increased $600,000 to $2.7 million from $2.1 million for the
six  month period, as a result of the aforementioned increase  in
sales and declines in SG&A.
     
     Other  non-operating income was approximately $4,000 in  the
three  month period of 1995 compared to approximately $14,000  of
other  non-operating expense in the comparable 1994 period.   For
the  1995  six month period, non-operating income was  $9,000  as
compared to income of $14,000 for the comparable 1994 period.
     
     Interest  expense increased approximately $500,000  to  $1.4
million in the second quarter of 1995 period from $900,000 in the
comparable  1994  period, as a result  of  the  increase  in  the
outstanding  balance  of the senior credit facility  and  related
interest rate.  Interest expense for the first six months of 1995
of  $2.6  million  is  an  increase  of  $1.0  million  from  the
comparable 1994 period interest expense of $1.6 million.
     
     The  Company  did not have an income tax provision  for  the
three month and six month periods ended June 30, 1995 as a result
of  utilization  of  net operating loss carryforwards.   For  the
comparable periods of 1994, the Company had provisions for income
taxes of $14,000 and $400,000, respectively.
     
Liquidity and Capital Resources

     For  the  six  months ended June 30, 1995, the Company  used
$3.4 million of cash in operating activities.  This was primarily
the result of the Company's effort to reduce its accounts payable
and  other  liabilities.  These uses of cash were funded  by  the
Company's credit facility, which resulted in an increase  in  the
credit  facility  during the first half of  1995.   However,  the
Company  also  had significant cash collections of  its  accounts
receivable  during  the  second quarter, which  has  reduced  the
credit  facility balance from March 31, 1995 to  June  30,  1995.
Operating cash uses and purchases of property and equipment  were
funded  from  borrowings of $4.3 million from the  senior  credit
facility.
     
     The  Company continues to have constraints on its  liquidity
as  it  funds  its  revenue growth and its product  and  bid  and
proposal  efforts.   The  Company has an active  cash  management
program   designed  to  monitor  and  control  significant   cash
commitments  as  well as to ensure sufficient funds  for  Company
operations and growth.

     At  June 30, 1995, the Company had outstanding debt of $45.4
million,  consisting of $38.3 million under  the  secured  senior
credit  facility  and  $7.1 million in  subordinated  debt.   The
senior credit facility was refinanced on April 17, 1995 and has a
maturity  date  of  July  1,  1996.   Under  the  terms  of   the
refinancing,  the  total  commitment  under  the  senior   credit
facility  remains  at  $45  million, with  terms  and  conditions
similar  to  the  previous  senior  credit  facility  except  for
amendments  made  to certain of the financial  and  non-financial
covenants.   In 1995, certain of the Company's shareholders  have
made deposits with the Company's bank to provide the Company with
increased   borrowing  capability  under  its  Facility.    Total
shareholder  deposits with the Company's bank total  $7  million.
The  Company  and  its  shareholders  have  agreed  to  negotiate
appropriate  return  to the shareholders for  this  provision  of
capital.    Such  negotiations  are  in  process.   The   Company
currently anticipates that the form of such return will  be  long
term  instruments substantially similar to the ones to be  issued
in exchange for the subordinated bridge notes, described below.
     
     At  June  30, 1995, the Company had $675,000 of  the  senior
subordinated  notes, Series A, outstanding  with  Mr.  John  R.C.
Porter  ("Porter"),  the Company's majority  common  shareholder.
The  Company was not in compliance with the financial maintenance
covenants of the senior subordinated notes, Series A as  of  June
30, 1995.  Porter has agreed to waive such non compliance.
     
      The Company entered into an agreement with Union de Banques
Suisses  (Luxembourg) S. A. ("UBS") on June 8, 1995  whereby  the
Company  paid UBS $5.8 million in outstanding principal, $500,000
of  accrued  interest and $200,000 of legal and  other  fees   in
satisfaction of the claims of UBS with respect to the Series  B-1
and B-2 notes.

     The  funds  to  pay  UBS were provided  by  certain  of  the
Company's common shareholders.  The shareholders have been issued
subordinated bridge notes aggregating approximately $6.5 million.
The  notes  have  a  maturity date of October 1,  1996  and  have
interest  rates  ranging  from 14% to 17  1/2%.   Currently,  the
Company   is  negotiating  terms  for  certain  long  term   debt
instruments  that  will  replace the subordinated  bridge  notes.
While  the  terms have not been finalized, these debt instruments
are  expected  to  bear similar stated interest and  may  contain
certain  substantial  prepayment premiums currently  expected  to
have a value of approximately 13 1/2% per annum which become  due
should specified events happen.

interest being payable as follows:

      a. Interest only, at the rate of fourteen percent (14%) per

      b. If not sooner paid, the outstanding and unpaid principal
balance shall be paid on or before October 1, 1996.

     c. Principal and interest on this note are payable in lawful
money  of the United States.  The principal and interest on  this
Note  may  be  prepaid at any time after ten  (10)  days  written
notice  to  the Lender, in whole or in part, without  premium  or

      d.  If  any payment of principal or interest on  this  Note

authorized by law or executive order to close, such payment shall

      e.  Upon  receipt  by  the Borrower of evidence  reasonably
satisfactory to it of the mutilation, destruction, loss or  theft

new  note  of  like  tenor  in lieu of this  Note  so  mutilated,
destroyed, lost or stolen.

     f. Payments made on account hereof shall be applied first to
accrued  and unpaid interest and the remainder shall be  credited

                           I.  DEFAULT
                                
      1.1  It is expressly agreed by Borrower that the failure to
pay, when due, any amount of principal, or no more than five days
after  due  date  any amount of interest, or  in  the  event  the
Borrower files any petition, or any petition is filed against  it
and not dismissed within sixty (60) days, under any bankruptcy or
insolvency  law  or  for  the  appointment  of  a  receiver   for
substantially all its assets or in the event the Borrower makes a
general assignment for the benefit of creditors, shall be  deemed
to be Events of Default under this Note.

      1.2    If  an Event of Default occurs, the lender,  at  his
option,  may  accelerate this Note and may by written  notice  to
Borrower declare the entire unpaid principal amount of this  Note
and all interest accrued and unpaid thereon to be immediately due
and  payable whereupon the unpaid principal amount and  all  such
accrued  interest shall become and be forthwith due and  payable,
without  presentment, demand, protest or further  notice  of  any
kind.  The failure of the Lender to give such notice shall, in no
event,  be  deemed a waiver of any of the Lender rights hereunder
as long as the Event of Default continues.

      1.3    Upon default in the payment of the principal of this
Note or any other sum payable hereunder when due upon demand,  at
maturity  or  by  reason  of acceleration of  maturity,  Borrower
agrees  to pay all costs of collection incurred by the holder  of
the  Note, including reasonable attorneys' fees, whether suit  is
brought  or  not,  and  all other costs and  expenses  reasonably
connected with collection of the indebtedness evidenced hereby.

                      II.     SUBORDINATION
                                
      This  Note  is  also  subject to the  following  terms  and
conditions and provisions with respect to a security interest.

      2.1   The Borrower, for itself, its successors and assigns,
covenants  and  agrees, and the Lender and each  holder  of  this
Note,  by his acceptance thereof, likewise covenants and  agrees,
that the payment of the principal of and interest on the Note  is
hereby  expressly subordinated in right of payment to  the  prior
payment  in  full of all indebtedness now and hereafter  due  and
owing  to  NationsBank, N.A. or to any participant,  assignee  or
successor under the Revolving and Reducing Senior Facility Credit
Agreement  dated  as  of  January 14, 1992,  as  amended  now  or
hereafter  or under any agreement with respect to the refinancing
of  any  such  indebtedness (collectively, the "Agreement")  (all
such indebtedness collectively "Senior Indebtedness").

     2.2   In the event of the occurrence of any Event of Default
under the Agreement, all principal and interest due on all Senior
Indebtedness  shall first be paid in full before any  payment  is
made  upon  the  Note,  and  in any such  event  any  payment  or
distribution of any kind or character, whether in cash,  property
or  securities  (other than shares of stock of  the  Company,  as
reorganized  and  readjusted, or securities  of  the  corporation
provided  for  by  a plan of reorganization or readjustment,  the
payment  of which is subordinated to the payment in full  of  all


Senior Indebtedness which may at the time be outstanding,)  which
shall  be made upon or in respect of the Note shall be paid  over
to  the  holders  of such Senior Indebtedness for application  in
payment thereof, unless and until such Senior Indebtedness  shall
have  been  paid  and  satisfied in full.  Without  limiting  the
foregoing,  no payment of principal shall be made upon  the  Note
without  the prior written consent of the holder(s) of a majority
of  the  Senior Indebtedness outstanding at the time of any  such
proposed payment.

     2.3   No present or future holder of any Senior Indebtedness
shall be prejudiced in his right to enforce subordination of  the
Note by any act or failure to act on the part of the Company.

     2.4   The provisions of this Note are solely for the purpose
of  defining  the  relative  rights  of  the  holders  of  Senior
Indebtedness on the one hand, and the holder of the Note  on  the
other  hand,  and  nothing herein shall impair,  as  between  the
Company and the Noteholder, the obligation of the Company to  pay
to the Noteholder the principal, if any, and interest on the Note
in  accordance with its terms, nor shall anything herein  prevent
the  Noteholder, upon default hereunder, provided the  Noteholder
shall  have first obtained the written approval of the  holder(s)
of  a  majority of the Senior Indebtedness then outstanding, from
exercising all remedies otherwise permitted by applicable law  or
hereunder, subject to the rights under this Section II of holders
of  Senior  Indebtedness  to payment of  all  cash,  property  or
securities otherwise payable or deliverable to the Noteholders.

      2.5    Subject  to  the  payment  in  full  of  all  Senior
Indebtedness, the holder of the Note shall be subrogated  to  the
rights  of the holders of Senior Indebtedness to receive payments
or  distributions  of assets of the Company made  on  the  Senior
Indebtedness  until  the principal of and interest  on  the  Note
shall be paid in full.

      This  Note  shall be construed and enforced  in  accordance
with,  and governed by the laws of the State of Virginia  without
giving effect to Conflict of Laws.

                           I.  DEFAULT
                                
      1.1  It is expressly agreed by Borrower that the failure to
pay, when due, any amount of principal, or no more than five days
after  due  date  any amount of interest, or  in  the  event  the
Borrower files any petition, or any petition is filed against  it
and not dismissed within sixty (60) days, under any bankruptcy or
insolvency  law  or  for  the  appointment  of  a  receiver   for

option,  may  accelerate this Note and may by written  notice  to
Borrower declare the entire unpaid principal amount of this  Note

and  payable whereupon the unpaid principal amount and  all  such
accrued  interest shall become and be forthwith due and  payable,
without  presentment, demand, protest or further  notice  of  any

distribution of any kind or character, whether in cash,  property
or  securities  (other than shares of stock of  the  Company,  as
reorganized  and  readjusted, or securities  of  the  corporation
provided  for  by  a plan of reorganization or readjustment,  the
payment  of which is subordinated to the payment in full  of  all


Senior Indebtedness which may at the time be outstanding,)  which

of  defining  the  relative  rights  of  the  holders  of  Senior
Indebtedness on the one hand, and the holder of the Note  on  the
other  hand,  and  nothing herein shall impair,  as  between  the

exercising all remedies otherwise permitted by applicable law  or
hereunder, subject to the rights under this Section II of holders
of  Senior  Indebtedness  to payment of  all  cash,  property  or
securities otherwise payable or deliverable to the Noteholders.

with,  and governed by the laws of the State of Virginia  without
giving effect to Conflict of Laws.

                           I.  DEFAULT
                                
      1.1  It is expressly agreed by Borrower that the failure to
pay, when due, any amount of principal, or no more than five days
after  due  date  any amount of interest, or  in  the  event  the
Borrower files any petition, or any petition is filed against  it
and not dismissed within sixty (60) days, under any bankruptcy or
insolvency  law  or  for  the  appointment  of  a  receiver   for
substantially all its assets or in the event the Borrower makes a
general assignment for the benefit of creditors, shall be  deemed
to be Events of Default under this Note.

      1.2    If  an Event of Default occurs, the lender,  at  his
option,  may  accelerate this Note and may by written  notice  to
Borrower declare the entire unpaid principal amount of this  Note
and all interest accrued and unpaid thereon to be immediately due
and  payable whereupon the unpaid principal amount and  all  such
accrued  interest shall become and be forthwith due and  payable,
without  presentment, demand, protest or further  notice  of  any
kind.  The failure of the Lender to give such notice shall, in no
event,  be  deemed a waiver of any of the Lender rights hereunder
as long as the Event of Default continues.

      1.3    Upon default in the payment of the principal of this
Note or any other sum payable hereunder when due upon demand,  at
maturity  or  by  reason  of acceleration of  maturity,  Borrower
agrees  to pay all costs of collection incurred by the holder  of
the  Note, including reasonable attorneys' fees, whether suit  is
brought  or  not,  and  all other costs and  expenses  reasonably
connected with collection of the indebtedness evidenced hereby.

                      II.     SUBORDINATION
                                
      This  Note  is  also  subject to the  following  terms  and
conditions and provisions with respect to a security interest.

      2.1   The Borrower, for itself, its successors and assigns,
covenants  and  agrees, and the Lender and each  holder  of  this
Note,  by his acceptance thereof, likewise covenants and  agrees,
that the payment of the principal of and interest on the Note  is
hereby  expressly subordinated in right of payment to  the  prior
payment  in  full of all indebtedness now and hereafter  due  and
owing  to  NationsBank, N.A. or to any participant,  assignee  or
successor under the Revolving and Reducing Senior Facility Credit
Agreement  dated  as  of  January 14, 1992,  as  amended  now  or
hereafter  or under any agreement with respect to the refinancing
of  any  such  indebtedness (collectively, the "Agreement")  (all
such indebtedness collectively "Senior Indebtedness").

     2.2   In the event of the occurrence of any Event of Default
under the Agreement, all principal and interest due on all Senior
Indebtedness  shall first be paid in full before any  payment  is
made  upon  the  Note,  and  in any such  event  any  payment  or
distribution of any kind or character, whether in cash,  property
or  securities  (other than shares of stock of  the  Company,  as
reorganized  and  readjusted, or securities  of  the  corporation
provided  for  by  a plan of reorganization or readjustment,  the
payment  of which is subordinated to the payment in full  of  all


Senior Indebtedness which may at the time be outstanding,)  which
shall  be made upon or in respect of the Note shall be paid  over
to  the  holders  of such Senior Indebtedness for application  in
payment thereof, unless and until such Senior Indebtedness  shall
have  been  paid  and  satisfied in full.  Without  limiting  the
foregoing,  no payment of principal shall be made upon  the  Note
without  the prior written consent of the holder(s) of a majority
of  the  Senior Indebtedness outstanding at the time of any  such
proposed payment.

     2.3   No present or future holder of any Senior Indebtedness
shall be prejudiced in his right to enforce subordination of  the
Note by any act or failure to act on the part of the Company.


     2.4   The provisions of this Note are solely for the purpose
of  defining  the  relative  rights  of  the  holders  of  Senior
Indebtedness on the one hand, and the holder of the Note  on  the
other  hand,  and  nothing herein shall impair,  as  between  the
Company and the Noteholder, the obligation of the Company to  pay
to the Noteholder the principal, if any, and interest on the Note
in  accordance with its terms, nor shall anything herein  prevent
the  Noteholder, upon default hereunder, provided the  Noteholder
shall  have first obtained the written approval of the  holder(s)
of  a  majority of the Senior Indebtedness then outstanding, from
exercising all remedies otherwise permitted by applicable law  or
hereunder, subject to the rights under this Section II of holders
of  Senior  Indebtedness  to payment of  all  cash,  property  or
securities otherwise payable or deliverable to the Noteholders.

      2.5    Subject  to  the  payment  in  full  of  all  Senior
Indebtedness, the holder of the Note shall be subrogated  to  the
rights  of the holders of Senior Indebtedness to receive payments
or  distributions  of assets of the Company made  on  the  Senior
Indebtedness  until  the principal of and interest  on  the  Note
shall be paid in full.

      This  Note  shall be construed and enforced  in  accordance
with,  and governed by the laws of the State of Virginia  without
giving effect to Conflict of Laws.
