Item  5.      Other Events.

     GTS Duratek,  Inc. ("GTS  Duratek" or the "Company")  announced that it had
entered into a $60 million credit  facility  underwritten  and arranged by First
Union Capital Markets Corporation to replace its existing facility. Participants
in the facility  include First Union  Commercial  Corporation,  National Bank of
Canada and Wachovia Bank.

     The credit facility includes a $35 million revolving line of credit,  based
on  the  amount  of  eligible  accounts   receivable,   to  refinance   existing
indebtedness and to fund working capital requirements, a $20 million acquisition
line of credit to finance  acquisitions  or stock  repurchases  and a $5 million
equipment line of credit to finance up to 75% of the Company's  acquisition cost
of new equipment  purchases.  Borrowings under the credit facility bear interest
initially  at either (i) the LIBOR  rate plus 2.25% or,  (ii) the Base Rate plus
1%, at the Company's  option.  The Base Rate is the higher of (a) the Prime Rate
(as defined in the Credit  Agreement)  and (b) the sum of the Federal Funds Rate
plus 1/2 of 1%. The interest rate is subject to adjustment  after June 30, 1999,
depending upon the Company's  ratio of debt to operating  income.  Substantially
all of the Company's assets,  excluding real property and inventory, are pledged
as collateral  under the credit  facility.  The credit  facility has a five year
term.  In  connection  with this new  facility,  GTS  Duratek has agreed to seek
stockholder  approval at its 1999 annual meeting of  stockholders  to extend the
mandatory redemption date of its outstanding  convertible preferred stock beyond
the maturity  date of this new facility;  if this approval is not obtained,  the
credit facility converts to a three year term.

              GTS DURATEK INCREASES CREDIT FACILITY TO $60 MILLION

     Columbia,  Md. - GTS Duratek,  Inc. (Nasdaq - DRTK) announced today that it
has entered  into a $60 million  credit  facility  underwritten  and arranged by
First Union Capital Markets  Corporation.  Participants in the facility  include
First Union Commercial Corporation,  National Bank of Canada, and Wachovia Bank.

     "We are pleased to have extended our  relationship  with these  prestigious
financial institutions. The increased credit facility will provide the necessary
resources  to fuel our  long-term  strategy  and enable us to take  advantage of
growth opportunities, such as possible acquisitions, as they arise." said Robert
E. Prince, President and CEO.

     Robert F. Shawver,  Executive Vice  President and CFO added,  "coupled with
the strong cash position generated from our operations, management believes that
GTS Duratek is uniquely  positioned to capitalize on these market  opportunities
by its size, breadth and technologies."

     David Sozio,  Managing  Director of First Union Capital  Markets Corp. said
"First  Union is pleased to arrange  this  financing.  We believe  that this new
credit  facility  represents  a major step in the  evolution  of the Company and
positions them well for further growth."

     The increased  credit  facility  includes a $35 million  revolving  line of
credit,  based on the  amount of  eligible  accounts  receivable,  to  refinance
existing  indebtedness and to fund working capital  requirements,  a $20 million
acquisition line of credit to finance acquisitions or stock repurchases and a $5
million  equipment  line  of  credit  to  finance  up to 75%  of  the  Company's
acquisition cost of new equipment purchases.  Substantially all of the Company's
assets,  excluding real property and inventory,  are pledged as collateral under
the credit  facility.  The credit  facility has a five year term.  In connection
with this new facility,  GTS Duratek has agreed to seek stockholder  approval at
its 1999 annual meeting of stockholders to extend the mandatory  redemption date
of its outstanding  convertible preferred stock beyond the maturity date of this
new facility; if this approval is not obtained,  the credit facility converts to
a three year term.

     GTS Duratek implements technologies and provides services many of which are
related to managing radiation and treating radioactive waste and other hazardous
waste.

     The  Company has  included in its  periodic  filings  under the  Securities
Exchange Act of 1934,  including its Form 10-Q for the quarter  ended  September
30,  1998,  pursuant to the "safe  harbor"  provisions  contained in the Private
Securities  Litigation Reform Act of 1995, certain  cautionary  statements which
are  intended  to  identify  certain  important  factors  that  could  cause the
Company's   actual  results  to  differ   materially  from  those  contained  in
forward-looking  statements  of the Company made by or on behalf of the Company.
Reference is made to such statements for a complete discussion of those factors,
which include the ability to manage the commercial waste  processing  operations
acquired  from SEG and to obtain  additional  waste  processing  contracts,  the
ability to extend the Savannah River M-Area  contract,  future awards by the DOE
and other  governmental  agencies,  public and  political  concerns  surrounding
radioactive  waste  clean-up  efforts,   and  the  timing  of  contract  awards,
extensions,  and  non-renewals in the technical  support services area. Also, as
stated herein, the timing of contracting  efforts, and timing and success in new
contract awards have affected  period-to-period  comparisons and are expected to
do so in the future.

the loss of the  amount  so  recovered  shall be  ratably  shared  among all the
Lenders  in  accordance  with  their  respective   Revolving  Credit  Commitment
Percentages  (unless the amounts so recovered  by or on behalf of the  Borrowers
pertain  to a  Swingline  Loan  extended  after the  occurrence  and  during the
continuance  of an Event  of  Default  of which  the  Administrative  Agent  has
received  actual  notice and which such Event of Default  has not been waived by

Lender will, on the date the  applicable  Revolving  Credit Loan would have been
made, purchase an undivided  participating  interest in the Swingline Loan to be
refunded in an amount equal to its Revolving Credit Commitment Percentage of the
aggregate amount of such Swingline Loan. Each Lender will  immediately  transfer
to the Swingline  Lender,  in  immediately  available  funds,  the amount of its
participation and upon receipt thereof the Swingline Lender will deliver to such
Lender a certificate  evidencing such participation dated the date of receipt of
such funds and for such amount. Whenever, at any time after the Swingline Lender
has received from any Lender such Lender's participating interest in a Swingline
Loan,  the  Swingline  Lender  receives  any  payment  on account  thereof,  the
Swingline  Lender will distribute to such Lender its  participating  interest in
such  amount  (appropriately  adjusted,  in the case of  interest  payments,  to
reflect the period of time during which such Lender's participating interest was
outstanding and funded).

                            LETTER OF CREDIT FACILITY

     SECTION  3.1 L/C  Commitment. 

     (a) Subject to the terms and  conditions  hereof,  the Issuing  Lender,  in
reliance on the  agreements  of the other  Lenders set forth in Section  3.4(a),
agrees to issue standby letters of credit  ("Letters of Credit") for the account
of the  Borrowers  on a joint and  several  basis on any  Business  Day from the
Closing Date through but not  including the  Revolving  Credit  Maturity Date in
such form as may be approved from time to time by the Issuing Lender;  provided,
that the Issuing  Lender shall have no  obligation to issue any Letter of Credit
if, after giving effect to such issuance,  (i) the L/C Obligations  would exceed
the L/C Commitment or (ii) the sum of (A) the L/C  Obligations at such time plus
(B) the aggregate principal amount of all outstanding Revolving Credit Loans and
Swingline Loans would exceed the then applicable Borrowing Limit. If at any time
the L/C Obligations exceed such permitted amount, the Borrowers shall furnish to
the  Administrative  Agent cash collateral  satisfactory  to the  Administrative
Agent in an amount equal to such excess to be applied in accordance with Section
12.2(b).  

     (b) Each Letter of Credit shall (i) be  denominated in Dollars in a minimum
amount of  $100,000,  (ii) be a  standby  letter  of  credit  issued to  support
obligations  of the  Borrowers  or  any of  their  Subsidiaries,  contingent  or
otherwise,  incurred in the ordinary course of business,  (iii) expire on a date
no later than one (1) year from the date of issuance thereof;  provided, that in
no case shall such  expiration  date be later than three (3) Business Days prior
to the Revolving Credit Maturity Date and (iv) be subject to the Uniform Customs
and, to the extent not  inconsistent  therewith,  the laws of the State of North
Carolina.  The Issuing  Lender  shall not at any time be  obligated to issue any
Letter of Credit  hereunder if such issuance  would  conflict with, or cause the
Issuing  Lender or any L/C  Participant  to exceed  any limits  imposed  by, any
Applicable  Law.  References  herein to "issue"  and  derivations  thereof  with
respect to Letters of Credit shall also include  extensions or  modifications of
any Existing Letters of Credit, unless the context otherwise requires.

     SECTION 3.2 Procedure for Issuance of Letters of Credit. The Borrowers may
from time to time  request  that the Issuing  Lender issue a Letter of Credit by
delivering  to the  Issuing  Lender  at the  Administrative  Agent's  Office  an
Application  therefor,  completed to the satisfaction of the Issuing Lender, and
such other  certificates,  documents  and other  papers and  information  as the
Issuing Lender may request. Upon receipt of any Application,  the Issuing Lender
shall process such Application and the certificates,  documents and other papers
and information  delivered to it in connection  therewith in accordance with its
customary  procedures  and shall,  subject to Section 3.1 and Article VI hereof,
promptly issue the Letter of Credit requested thereby (but in no event shall the
Issuing  Lender be required to issue any Letter of Credit earlier than three (3)
Business Days after its receipt of the  Application  therefor and all such other
certificates,  documents and other papers and information  relating  thereto) by
issuing the original of such Letter of Credit to the  beneficiary  thereof or as
otherwise  may be agreed by the Issuing  Lender and the  Borrowers.  The Issuing
Lender shall  promptly  furnish to the Borrowers a copy of such Letter of Credit
and promptly  notify each Lender of the issuance and upon request by any Lender,
furnish  to such  Lender a copy of such  Letter of Credit and the amount of such
Lender's L/C Participation therein.

                                       26

     SECTION 3.3 Commissions and Other Charges.

     (a) The Borrowers shall pay to the Administrative Agent, for the account of
the Issuing Lender and the L/C Participants,  a letter of credit commission with
respect to each  Letter of Credit in an amount  equal to the  product of (i) the
face amount of such Letter of Credit  times (ii) an annual  percentage  equal to
the Applicable  Margin with respect to LIBOR Rate Loans in effect on the date of
issuance of such Letter of Credit. Such commission shall be payable quarterly in
arrears on the last Business Day of each  calendar  quarter and on the Revolving
Credit Maturity Date.

     (b) In addition to the foregoing  commission,  the Borrowers  shall pay the
Issuing  Lender an  issuance  fee of 0.125% per annum on the face amount of each
Letter of Credit,  payable quarterly in arrears on the last Business Day of each
calendar quarter and on the Revolving Credit Maturity Date; provided,  that such
issuance  fee shall not be  payable  with  respect  to the  Existing  Letters of
Credit.

     (c) The  Borrowers  shall also pay all  normal  costs and  expenses  of the
Issuing Lender in connection with the issuance, transfer or other administration
of the Letters of Credit.

     (d) The Administrative Agent shall, promptly following its receipt thereof,
distribute  to the  Issuing  Lender  and the L/C  Participants  all  commissions
received  by the  Administrative  Agent  in  accordance  with  their  respective
Revolving Credit Commitment Percentages.

     SECTION 3.4 L/C Participations.

     (a) The Issuing  Lender  irrevocably  agrees to grant and hereby  grants to
each L/C  Participant,  and,  to induce the Issuing  Lender to issue  Letters of
Credit hereunder, each L/C Participant irrevocably agrees to accept and purchase
and hereby  accepts  and  purchases  from the Issuing  Lender,  on the terms and
conditions  hereinafter  stated, for such L/C Participant's own account and risk
an  undivided  interest  equal  to  such  L/C  Participant's   Revolving  Credit
Commitment  Percentage in the Issuing Lender's obligations and rights under each
Letter of Credit  issued  hereunder  and the  amount of each  draft  paid by the
Issuing Lender thereunder.  Each L/C Participant unconditionally and irrevocably
agrees  with the  Issuing  Lender  that,  if a draft is paid under any Letter of
Credit for which the Issuing  Lender is not  reimbursed in full by the Borrowers
in accordance with the terms of this Agreement,  such L/C Participant  shall pay
to the Issuing  Lender upon demand at the Issuing  Lender's  address for notices
specified  herein an amount  equal to such L/C  Participant's  Revolving  Credit
Commitment Percentage of the amount of such draft, or any part thereof, which is
not so reimbursed.

                                       27
<PAGE>

     (b)  Upon  becoming  aware  of any  amount  required  to be paid by any L/C
Participant to the Issuing Lender pursuant to  Section 3.4(a)  in respect of any
unreimbursed  portion of any payment made by the Issuing Lender under any Letter
of Credit,  the Issuing  Lender shall notify each L/C  Participant of the amount
and due date of such required payment and such L/C Participant  shall pay to the
Issuing  Lender the amount  specified on the  applicable  due date.  If any such
amount is paid to the Issuing  Lender after the date such  payment is due,  such
L/C Participant  shall pay to the Issuing Lender on demand,  in addition to such
amount,  the product of (i) such amount,  times (ii) the daily  average  Federal
Funds Rate as determined by the Administrative  Agent during the period from and
including  the date such  payment  is due to the date on which  such  payment is
immediately  available  to the  Issuing  Lender,  times  (iii)  a  fraction  the
numerator of which is the number of days that elapse  during such period and the
denominator of which is 360. A certificate of the Issuing Lender with respect to
any amounts  owing under this Section  3.4(b) shall be conclusive in the absence
of  manifest  error.  With  respect  to  payment  to the  Issuing  Lender of the
unreimbursed  amounts  described in this Section 3.4(b), if the L/C Participants
receive  notice that any such  payment is due (A) prior to 1:00 p.m.  (Charlotte
time) on any Business  Day, such payment shall be due that Business Day, and (B)
after 1:00 p.m.  (Charlotte time) on any Business Day, such payment shall be due
on the following Business Day.

     (c) Whenever,  at any time after the Issuing  Lender has made payment under
any Letter of Credit and has received  from any L/C  Participant  its  Revolving
Credit  Commitment  Percentage of such payment in  accordance  with this Section
3.4, the Issuing  Lender  receives any payment  related to such Letter of Credit
(whether directly from any Borrower or otherwise), or any payment of interest on
account thereof,  the Issuing Lender will distribute to such L/C Participant its
pro rata  share  thereof;  provided,  that in the  event  that any such  payment
received by the Issuing  Lender  shall be required to be returned by the Issuing
Lender,  such L/C  Participant  shall  return to the Issuing  Lender the portion
thereof previously distributed by the Issuing Lender to it.

     SECTION 3.5  Reimbursement  Obligation  of the  Borrowers. The  Borrowers
jointly and  severally  agree to  reimburse  the Issuing  Lender on each date on
which the Issuing  Lender  notifies  the  Borrowers  of the date and amount of a
draft  paid  under any Letter of Credit for the amount of (a) such draft so paid
and (b) any taxes,  fees,  charges or other  costs or  expenses  incurred by the
Issuing Lender in connection with such payment.  Each such payment shall be made
to the Issuing  Lender at its address  for  notices  specified  herein in lawful
money of the United States and in immediately available funds. Interest shall be
payable on any and all  amounts  remaining  unpaid by the  Borrowers  under this
Article  III from the date  such  amounts  become  payable  (whether  at  stated
maturity,  by acceleration or otherwise) until payment in full at the rate which
would be payable on any  outstanding  Base Rate Loans  which were then  overdue.
Unless the Borrowers have otherwise  previously  reimbursed the Issuing  Lender,
then on the date on which the Issuing Lender  notifies the Borrowers of the date
and amount of a draft paid under any Letter of Credit,  the  Borrowers  shall be
deemed to have timely  given a Notice of  Revolving  Credit/Swingline  Borrowing
hereunder to the Administrative Agent requesting the Lenders to make a Base Rate
Loan  on such  date in an  amount  equal  to the  amount  of such  drawing  and,
regardless of whether or not the  conditions  precedent  specified in Article VI
have been satisfied,  the Lenders shall make Base Rate Loans in such amount, the
proceeds  of which  shall be applied to  reimburse  the  Issuing  Lender for the
amount of the related drawing and costs and expenses.

                                       28
<PAGE>

     SECTION 3.6  Obligations  Absolute. The obligations of the Borrowers under
this Article III (including  without  limitation the  Reimbursement  Obligation)
shall  be  absolute  and  unconditional  under  any  and all  circumstances  and
irrespective  of any  set-off,  counterclaim  or defense  to  payment  which the
Borrowers may have or have had against the Issuing Lender or any  beneficiary of
a Letter of Credit.  The Borrowers  also agree with the Issuing  Lender that the
Issuing Lender shall not be responsible for, and the Reimbursement Obligation of
the  Borrowers  under  Section 3.5 shall not be affected by, among other things,
the validity or genuineness of documents or of any  endorsements  thereon,  even
though such documents  shall in fact prove to be invalid,  fraudulent or forged,
or any dispute  between or among the Borrowers and any beneficiary of any Letter
of Credit or any other party to which such  Letter of Credit may be  transferred
or any claims whatsoever of a Borrower against any beneficiary of such Letter of
Credit or any such  transferee.  The Issuing  Lender shall not be liable for any
error, omission, interruption or delay in transmission,  dispatch or delivery of
any message or advice,  however  transmitted,  in connection  with any Letter of
Credit,  except for errors or  omissions  caused by the Issuing  Lender's  gross
negligence or willful  misconduct.  The Borrowers agree that any action taken or
omitted by the Issuing  Lender under or in connection  with any Letter of Credit
or the related drafts or documents,  if done in the absence of gross  negligence
or willful  misconduct and in accordance with the standards of care specified in
the Uniform Customs and, to the extent not inconsistent therewith, the UCC shall
be binding on the Borrowers and shall not result in any liability of the Issuing
Lender  to the  Borrowers.  The  responsibility  of the  Issuing  Lender  to the
Borrowers in connection with any draft presented for payment under any Letter of
Credit shall, in addition to any payment  obligation  expressly  provided for in
such Letter of Credit,  be limited to determining that the documents  (including
each  draft)  delivered  under  such  Letter of Credit in  connection  with such
presentment are in conformity with such Letter of Credit.

     SECTION 3.7 Effect of Application . To the extent that any provision of any
Application  related to any Letter of Credit is inconsistent with the provisions
of this Article III, the provisions of this Article III shall apply.

repayment  of a LIBOR  Rate  Loan to prepay  the Term  Loans in whole or in part
without premium or penalty except as provided below and as required  pursuant to
Section 5.9. Upon receipt of any such notice, the Administrative  Agent promptly

Term  Loans  hereunder  shall be in an  aggregate  principal  amount of at least
$1,000,000 or any whole  multiple of $250,000 in excess  thereof with respect to
Base Rate Loans and  $2,000,000  or any whole  multiple  of  $500,000  in excess
thereof  with respect to LIBOR Rate Loans,  shall be applied to the  outstanding
principal  balance of the Term Loans on a pro rata basis between the Term A Loan
Facility  and the Term B Loan  Facility on a pro rata basis among each  separate
Term Loan under each such facility to reduce the remaining  scheduled  principal
installments  of the separate  outstanding  Term Loans under each such facility.

so notify the  Lenders.  Each  prepayment  under this  Section  4.4(b)  shall be
applied to reduce on a pro rata basis in inverse order of maturity the remaining
scheduled principal installments of the Term A Loans.

                                       31
<PAGE>

     (c) No  Reborrowing  of Term Loans.  Amounts  prepaid  under the Term Loans
pursuant to Section 4.3 or Section 4.4 may not be reborrowed and will constitute
a permanent  reduction in the applicable Term Loan  Commitment.  Each prepayment

Lender  representing the Borrowers'  obligation to pay such Lender's Term B Loan
Commitment  in  accordance  with the terms  hereof.  Each Term Note  shall  bear
interest on the unpaid principal amount thereof at the applicable  interest rate
per annum specified in Section 5.1.

                             GENERAL LOAN PROVISIONS

    SECTION 5.1 Interest.

     (a) Interest Rate Options.  Subject to the  provisions of this Section 5.1,
at the  election  of GTS on behalf of the  Borrowers,  the  aggregate  principal
balance of any Revolving  Credit Note and any Term Loan Note shall bear interest
at (i) the Base Rate plus the  Applicable  Margin as set forth in Section 5.1(c)
or (ii) the LIBOR  Rate  plus the  Applicable  Margin  as set  forth in  Section
5.1(c);  provided  that the LIBOR Rate shall not be  available  until  three (3)
Business Days after the Closing Date.  The Swingline Note shall bear interest at
the Base Rate plus the  Applicable  Margin as set forth in Section  5.1(c).  The
Borrowers  shall  select  the rate of  interest  and  Interest  Period,  if any,
applicable  to any  Loan at the  time a  Notice  of  Revolving  Credit/Swingline
Borrowing is given pursuant to Section 2.3(a) or a Notice of Term Loan Borrowing
is   given   pursuant   to   Section   4.2  or  at  the   time   a   Notice   of
Conversion/Continuation  is given  pursuant to Section 5.2. Each Loan or portion
thereof  bearing  interest based on the Base Rate (other than  Swingline  Loans)
shall be a "Base Rate Loan", each Loan or portion thereof bearing interest based
on the LIBOR Rate shall be a "LIBOR Rate Loan." Any Loan or any portion  thereof
as to which the Borrowers  have not duly  specified an interest rate as provided
herein shall be deemed a Base Rate Loan.

     (b)  Interest  Periods.  In  connection  with each LIBOR Rate Loan,  GTS on
behalf of the  Borrowers,  by giving  notice at the times  described  in Section
5.1(a),  shall elect an  interest  period  (each,  an  "Interest  Period") to be
applicable to such LIBOR Rate Loan,  which Interest  Period shall be a period of
one (1),  two (2),  three (3), or six (6) months with respect to each LIBOR Rate
Loan; provided that:

                                       32
<PAGE>

     (i) the  Interest  Period  shall  commence  on the  date of  advance  of or
conversion  to any LIBOR Rate Loan and,  in the case of  immediately  successive
Interest Periods,  each successive Interest Period shall commence on the date on
which the next preceding Interest Period expires;

     (ii) if any Interest Period would  otherwise  expire on a day that is not a
Business Day, such Interest Period shall expire on the next succeeding  Business
Day;  provided,  that if any  Interest  Period with respect to a LIBOR Rate Loan
would  otherwise  expire on a day that is not a Business Day but is a day of the
month after which no further  Business Day occurs in such month,  such  Interest
Period shall expire on the next preceding Business Day;

     (iii) any Interest  Period with respect to a LIBOR Rate Loan that begins on
the last  Business  Day of a calendar  month (or on a day for which  there is no
numerically  corresponding day in the calendar month at the end of such Interest
Period) shall end on the last Business Day of the relevant calendar month at the
end of such Interest Period;

     (iv)  no  Interest   Period  shall  extend  beyond  the  Revolving   Credit
Termination  Date,  the Term A Loan  Maturity  Date or the Term B Loan  Maturity
Date,  as  applicable,  no Interest  Periods  shall be selected by the Borrowers
which would  result in the  repayment of any LIBOR Rate Loan prior to the end of
an Interest Period; and

     (v) there shall be no more than six (6)  Interest  Periods in effect at any
time.

     (c) Applicable Margin. The Applicable Margin provided for in Section 5.1(a)
with  respect to the Loans (the  "Applicable  Margin")  shall (i) on the Closing
Date and for the fiscal  quarters  ending March 31, 1999 and June 30, 1999 equal
1.00% with respect to Base Rate Loans and Swingline Loans and 2.25% with respect
to LIBOR Rate Loans and (ii) for each fiscal quarter thereafter be determined by
reference to the Leverage Ratio as of the end of the fiscal quarter  immediately
preceding the delivery of the  applicable  Officer's  Compliance  Certificate as
follows:


              Leverage                               Applicable Margin Per Annum
Level         Ratio                                  Base Rate +    LIBOR Rate +
- -----         -----                                  ---------------------------

  3           Greater than 2.00 to 1.00 but
              Less than or equal to 2.50 to 1.00          0.75%            2.00%

  4           Less than or equal to 2.00 to 1.00          0.50%            1.75%

<PAGE>

Adjustments,   if  any,  in  the   Applicable   Margin  shall  be  made  by  the
Administrative  Agent on the tenth  (10th)  Business  Day after  receipt  by the
Administrative  Agent of quarterly  financial  statements  for the Borrowers and
their Subsidiaries and the accompanying Officer's Compliance Certificate setting
forth the Leverage Ratio of the Borrowers and their  Subsidiaries as of the most
recent fiscal quarter end. In addition to any increase,  if any, in the interest
rate purusant to Section 5.1(d), in the event the Borrowers fail to deliver such
financial  statements and  certificate  within the time required by Sections 8.1
and 8.2 hereof, the Applicable Margin shall be the highest Applicable Margin set
forth above until the delivery of such financial statements and certificate.

     (d)  Default  Rate.  Subject  to Section  12.3,  at the  discretion  of the
Administrative  Agent and Required  Lenders,  upon the occurrence and during the
continuance of an Event of Default,  (i) the Borrowers  shall no longer have the
option to request  LIBOR Rate Loans or  Swingline  Loans,  (ii) all  outstanding
LIBOR Rate Loans shall bear  interest  at a rate per annum two  percent  (2%) in
excess of the rate then applicable to LIBOR Rate Loans, as applicable, until the
end of the  applicable  Interest  Period and  thereafter  at a rate equal to two
percent  (2%)  in  excess  of the  rate  then  applicable  to  Base  Rate  Loans
(calculated at the highest  Applicable  Margin),  and (iii) all outstanding Base
Rate Loans and Swingline  Loans shall bear interest at a rate per annum equal to
two  percent  (2%) in  excess of the rate then  applicable  to Base Rate  Loans.
Interest  shall  continue  to accrue on the Notes after the filing by or against
any Borrower of any petition  seeking any relief in  bankruptcy or under any act
or law  pertaining to insolvency or debtor  relief,  whether  state,  federal or
foreign.

     (e) Interest Payment and  Computation.  Interest on each Base Rate Loan and
Swingline  Loans  shall be payable in arrears on the last  Business  Day of each
calendar quarter commencing March 31, 1999; and interest on each LIBOR Rate Loan
shall be payable on the last day of each Interest Period applicable thereto, and
if such Interest Period extends over three (3) months,  at the end of each three
(3) month interval during such Interest  Period.  All interest  rates,  fees and
commissions  provided hereunder shall be computed on the basis of a 360-day year
and assessed for the actual number of days elapsed.

     (f) Maximum Rate. In no contingency or event whatsoever shall the aggregate
of all amounts  deemed  interest  hereunder or under any of the Notes charged or
collected  pursuant  to the terms of this  Agreement  or  pursuant to any of the
Notes exceed the highest rate permissible under any Applicable Law which a court
of competent  jurisdiction  shall,  in a final  determination,  deem  applicable
hereto.  In the event that such a court determines that the Lenders have charged
or received  interest  hereunder in excess of the highest  applicable  rate, the
rate in effect  hereunder  shall  automatically  be reduced to the maximum  rate
permitted by Applicable Law and the Lenders shall at the Administrative  Agent's
option (i) promptly refund to the Borrowers any interest  received by Lenders in
excess  of the  maximum  lawful  rate or (ii)  shall  apply  such  excess to the
principal balance of the Obligations. It is the intent hereof that the Borrowers
not pay or contract to pay,  and that neither the  Administrative  Agent nor any
Lender  receive or  contract to receive,  directly or  indirectly  in any manner
whatsoever,  interest in excess of that which may be paid by the Borrowers under
Applicable Law.

     SECTION  5.2 Notice and Manner of  Conversion  or  Continuation  of Loans.
Provided  that no Event of Default  has  occurred  and is then  continuing,  the
Borrowers  shall  have the option to  convert  at any time  following  the third
Business Day after the Closing Date all or any portion of its  outstanding  Base
Rate  Loans  (other  than  Swingline  Loans)  in a  principal  amount  equal  to
$2,000,000 or any whole  multiple of $500,000 in excess thereof into one or more
LIBOR Rate Loans and (b) upon the expiration of any Interest Period, (i) convert
all or any part of its outstanding  LIBOR Rate Loans in a principal amount equal
to $1,000,000 or a whole  multiple of $250,000 in excess  thereof into Base Rate
Loans or (ii) continue  such LIBOR Rate Loans as LIBOR Rate Loans.  Whenever the
Borrowers  desire to convert or continue Loans as provided above,  GTS on behalf
of the Borrowers shall give the  Administrative  Agent irrevocable prior written
notice in the form attached as Exhibit F (a "Notice of Conversion/Continuation")
not later than 11:00 a.m.  (Charlotte  time) three (3) Business  Days before the
day on  which a  proposed  conversion  or  continuation  of  such  Loan is to be
effective  specifying  (A) the Loans to be converted or  continued,  and, in the
case of any LIBOR Rate Loan to be  converted or  continued,  the last day of the
Interest  Period  therefor  specifying  the Credit  Facility  to which such Loan
relates,  (B) the effective date of such conversion or continuation (which shall
be a Business  Day),  (C) the principal  amount of such Loans to be converted or
continued,  and (D) the Interest  Period to be applicable  to such  converted or
continued  LIBOR Rate Loan. The  Administrative  Agent shall promptly notify the
Lenders of such Notice of Conversion/Continuation.

     SECTION 5.3 Fees.

     (a) Commitment Fee.  Commencing on the Closing Date and continuing  through
but excluding the Revolving Credit Maturity Date, the Borrowers shall pay to the
Administrative   Agent,  for  the  account  of  the  Lenders,  a  non-refundable
commitment  fee at a rate per  annum  equal to the rate  set  forth  below  (the
"Commitment  Fee Rate") on the average  daily  unused  portion of the  Aggregate
Commitment (the outstanding  principal  balance of all Loans and L/C Obligations
shall be considered  usage).  The  commitment fee shall be payable in arrears on
the last Business Day of each calendar quarter commencing March 31, 1999, and on
the Revolving  Credit Maturity Date. Such commitment fee shall be distributed by
the Administrative Agent to the Lenders pro rata in accordance with the Lenders'
respective  Commitment  Percentages.  The Commitment Fee Rate provided for above
shall equal the percentage set forth below  corresponding  to the level at which
the  Applicable  Margin is  determined in accordance  with Section  5.1(c).  Any
change in the applicable  level at which  Applicable  Margin is determined shall
result in a corresponding and simultaneous change in the Commitment Fee Rate.

                  Level                              Commitment Fee Rate
                  -----                              -------------------

                    1                                       0.500%

                    2                                       0.375%

                    3                                       0.375%

                    4                                       0.375%

     (b)  Administrative  Agent's and Other  Fees.  In order to  compensate  the
Administrative  Agent  for  structuring  and  syndicating  the Loans and for its
obligations  hereunder,  the Borrowers agree to pay to the Administrative Agent,
for its  account,  the  fees set  forth in the  separate  fee  letter  agreement
executed  by the GTS,  on  behalf of itself  and the  other  Borrowers,  and the
Administrative Agent dated November 6, 1998.

     SECTION  5.4  Manner of  Payment. (a) Each  payment  by the  Borrowers  on
account of the principal of or interest on the Revolving  Credit Loans or of any
fee,  commission  or other  amounts  (including  the  Reimbursement  Obligation)
payable to the Lenders under this Agreement with respect to the Revolving Credit
Loans,  the  Letters of Credit or any  Revolving  Credit  Note shall be made not
later than 1:00 p.m.  (Charlotte  time) on the date  specified for payment under
this Agreement to the Administrative Agent at the Administrative  Agent's Office
for the  account  of the  Lenders  (other  than as set forth  below) pro rata in
accordance  with  their  respective  Revolving  Credit  Commitment  Percentages,
(except as specified below) in Dollars, in immediately available funds and shall
be made without any set-off,  counterclaim  or  deduction  whatsoever,  (b) each
payment to the  Administrative  Agent on account of the principal of or interest
on the Swingline Loans or of any fee,  commission or other amounts shall be made
in like manner, except for the account of the Swingline Lender, (c) each payment
by the  Borrowers on account of the principal of or interest on the Term A Loans
or of any fee,  commission  or other  amounts  payable to the Lenders under this
Agreement  with  respect to the Term A Loans or any Term A Note shall be made in
like manner,  except for the account of the Lenders pro rata in accordance  with
their respective Term A Loan  Percentages,  (d) each payment by the Borrowers on
account  of the  principal  of or  interest  on the  Term B Loans or of any fee,
commission or other amounts  payable to the Lenders  under this  Agreement  with
respect  to the Term B Loans or any  Term B Note  shall be made in like  manner,
except  for the  account  of the  Lenders  pro  rata in  accordance  with  their
respective  Term B Loan  Percentages  and (e) any other  amounts  payable to the
Lenders  under  this  Agreement  shall be made in like  manner,  except  for the
account of the  Lenders pro rata based on its or their  respective  share in the
Obligation with respect to which such payment was received. Any payment received
after  such  time but  before  2:00 p.m.  (Charlotte  time) on such day shall be
deemed a payment  on such date for the  purposes  of Section  12.1,  but for all
other purposes shall be deemed to have been made on the next succeeding Business

receipt by the  Administrative  Agent of each such payment,  the  Administrative
Agent  shall  distribute  to each  Lender at its  address  for notices set forth
herein  its pro rata  share of such  payment in  accordance  with such  Lender's
Commitment  Percentage  (except as specified below) and shall wire advice of the
amount of such credit to each Lender.  Each payment to the Administrative  Agent
of the Issuing Lender's fees or L/C  Participants'  commissions shall be made in
like manner,  but for the account of the Issuing Lender or the L/C  Participant,
as  the  case  may  be.  Each  payment  to  the  Administrative   Agent  of  the
Administrative  Agent's or Issuing  Lender's fees or expenses  shall be made for
the account of the  Administrative  Agent or Issuing Lender, as the case may be,

under this  Agreement or any Note shall be specified to be made upon a day which
is not a Business  Day, it shall be made on the next  succeeding  day which is a
Business  Day and such  extension  of time  shall in such  case be  included  in
computing any interest if payable along with such payment.

     SECTION  5.5  Crediting  of Payments  and  Proceeds. In the event that the
Borrowers shall fail to pay any of the Obligations  when due and the Obligations
have been  accelerated  pursuant to Section 12.2,  all payments  received by the
Lenders upon the Notes and the other  Obligations  and all net proceeds from the
enforcement of the  Obligations  shall be applied first to all expenses then due
and payable by the Borrowers hereunder,  then to all indemnity  obligations then
due and payable by the Borrowers hereunder,  then to all Administrative  Agent's
and Issuing Lender's fees then due and payable, then to all commitment and other
fees and commissions  then due and payable,  then to accrued and unpaid interest
on the Swingline  Note to the  Swingline  Lender,  then to the principal  amount
outstanding  under the Swingline Note to the Swingline  Lender,  then to accrued
and unpaid  interest on the other Notes and the  Reimbursement  Obligation  (pro
rata in accordance with all such amounts due),  then to the principal  amount of
the other Notes and Reimbursement Obligation and any termination payments due in
respect of a Hedging  Agreement with any Lender (which such Hedging Agreement is
permitted hereunder and required or requested by the Required Lenders) (pro rata
in accordance with all such amounts due) and then to the cash collateral account
described in Section  12.2(b) hereof to the extent of any L/C  Obligations  then
outstanding,  then to any  termination  payments  due in  respect  of a  Hedging
Agreement  with any Lender (which such Hedging  Agreement is permitted,  but not
required or requested by the Required Lenders), in that order.

     SECTION 5.6 Adjustments. If any Lender (a "Benefited Lender") shall at any
time  receive  any  payment  of all or part of the  Obligations  owing to it, or
interest  thereon,  or if any Lender shall at any time receive any collateral in
respect of the Obligations owing to it (whether voluntarily or involuntarily, by
set-off  or  otherwise)  in a greater  proportion  than any such  payment to and
collateral  received by any other Lender,  if any, in respect of the Obligations
owing to such other Lender,  or interest  thereon,  such Benefited  Lender shall
purchase  for cash from the  other  Lenders  such  portion  of each  such  other
Lender's  Extensions  of Credit,  or shall  provide such other  Lenders with the
benefits of any such collateral,  or the proceeds thereof, as shall be necessary
to cause such  Benefited  Lender to share the excess payment or benefits of such
collateral or proceeds ratably with each of the Lenders;  provided,  that if all
or any portion of such excess  payment or benefits is thereafter  recovered from
such Benefited Lender, such purchase shall be rescinded,  and the purchase price
and benefits returned to the extent of such recovery,  but without interest. The
Borrowers  agree that each Lender so  purchasing  a portion of another  Lender's
Extensions  of Credit may  exercise  all rights of payment  (including,  without
limitation,  rights of set-off) with respect to such portion as fully as if such
Lender were the direct holder of such portion.

     SECTION  5.7 Nature of  Obligations  of  Lenders  Regarding  Extensions  of
Credit;  Assumption by the Administrative Agent. The obligations of the Lenders
under this  Agreement to make the Loans and issue or  participate  in Letters of
Credit  are  several  and are  not  joint  or  joint  and  several.  Unless  the
Administrative  Agent  shall  have  received  notice  from a  Lender  prior to a
proposed  borrowing  date  that  such  Lender  will  not make  available  to the
Administrative  Agent such Lender's ratable portion of the amount to be borrowed
on such date  (which  notice  shall not release  such Lender of its  obligations
hereunder),  the Administrative  Agent may assume that such Lender has made such
portion available to the Administrative  Agent on the proposed borrowing date in
accordance  with Sections 2.3(b) and 4.2, and the  Administrative  Agent may, in
reliance upon such  assumption,  make  available to the Borrowers on such date a
corresponding  amount.  If such amount is made  available to the  Administrative
Agent  on a date  after  such  borrowing  date,  such  Lender  shall  pay to the
Administrative  Agent on demand an amount,  until paid,  equal to the product of
(a) the amount of such Lender's Commitment  Percentage of such borrowing,  times
(b) the daily average Federal Funds Rate during such period as determined by the
Administrative  Agent, times (c) a fraction the numerator of which is the number
of days that elapse from and including  such borrowing date to the date on which
Lender's  Commitment  Percentage of such borrowing shall have become immediately
available to the  Administrative  Agent and the  denominator  of which is 360. A
certificate of the Administrative  Agent with respect to any amounts owing under
this Section 5.7 shall be conclusive,  absent  manifest  error. If such Lender's
Commitment   Percentage  of  such   borrowing  is  not  made  available  to  the
Administrative  Agent by such  Lender  within  three (3)  Business  Days of such
borrowing  date,  the  Administrative  Agent shall be  entitled to recover  such
amount made available by the  Administrative  Agent with interest thereon at the
rate per annum  applicable  to Base Rate Loans  hereunder,  on demand,  from the
Borrowers.  The failure of any Lender to make its  Revolving  Credit  Commitment
Percentage,  Term A Loan Percentage or Term B Loan Percentage, as applicable, of
any Loan available  shall not relieve it or any other Lender of its  obligation,
if any,  hereunder to make its Revolving Credit  Commitment  Percentage,  Term A
Loan Percentage or Term B Loan Percentage, as applicable, of such Loan available
on such borrowing  date,  but no Lender shall be responsible  for the failure of
any other Lender to make its Revolving Credit Commitment Percentage, Term A Loan
Percentage or Term B Loan Percentage,  as applicable,  of such Loan available on
the borrowing date.

     SECTION 5.8 Changed Circumstances.

     (a) Circumstances Affecting LIBOR Rate Availability. If with respect to any
Interest Period the Administrative  Agent or any Lender (after consultation with
Administrative Agent) shall determine that, by reason of circumstances affecting
the foreign exchange and interbank markets  generally,  deposits in eurodollars,
in the applicable amounts are not being quoted via Telerate Page 3750 or offered
to the  Administrative  Agent or such Lender for such Interest Period,  then the
Administrative  Agent  shall  forthwith  give notice  thereof to the  Borrowers.
Thereafter,  until the  Administrative  Agent  notifies the Borrowers  that such
circumstances  no longer exist, the obligation of the Lenders to make LIBOR Rate
Loans and the right of the Borrowers to convert any Loan to or continue any Loan
as a LIBOR Rate Loan shall be suspended,  and the Borrowers  shall repay in full
(or cause to be repaid in full) the then  outstanding  principal  amount of each
such LIBOR Rate Loans together with accrued interest thereon, on the last day of
the then current  Interest Period  applicable to such LIBOR Rate Loan or convert
the then  outstanding  principal  amount of each such  LIBOR Rate Loan to a Base
Rate Loan as of the last day of such Interest Period.

     (b) Laws Affecting LIBOR Rate Availability.  If, after the date hereof, the
introduction  of, or any  change  in,  any  Applicable  Law or any change in the
interpretation or administration thereof by any Governmental Authority,  central
bank or comparable  agency  charged with the  interpretation  or  administration
thereof,  or  compliance  by any  Lender  (or any of  their  respective  Lending
Offices) with any request or directive  (whether or not having the force of law)
of any such Authority, central bank or comparable agency, shall make it unlawful
or  impossible  for any of the  Lenders  (or  any of  their  respective  Lending
Offices) to honor its  obligations  hereunder to make or maintain any LIBOR Rate
Loan, such Lender shall promptly give notice thereof to the Administrative Agent
and the Administrative Agent shall promptly give notice to the Borrowers and the
other Lenders. Thereafter, until the Administrative Agent notifies the Borrowers
that such  circumstances  no longer exist, (i) the obligations of the Lenders to
make  LIBOR  Rate Loans and the right of the  Borrowers  to convert  any Loan or
continue any Loan as a LIBOR Rate Loan shall be  suspended  and  thereafter  the
Borrowers  may  select  only Base Rate Loans  hereunder,  and (ii) if any of the
Lenders  may not  lawfully  continue to maintain a LIBOR Rate Loan to the end of
the then current  Interest Period  applicable  thereto as a LIBOR Rate Loan, the
applicable  LIBOR Rate Loan shall  immediately  be converted to a Base Rate Loan
for the remainder of such Interest Period.

                                       38

     (c) Increased Costs. If, after the date hereof, the introduction of, or any
change  in, any  Applicable  Law,  or in the  interpretation  or  administration
thereof by any Governmental Authority, central bank or comparable agency charged
with the interpretation or administration  thereof,  or compliance by any of the
Lenders  (or any of  their  respective  Lending  Offices)  with any  request  or
directive  (whether or not having the force of law) of such  Authority,  central
bank or comparable agency:

     (i) shall  subject any of the Lenders (or any of their  respective  Lending
Offices) to any tax,  duty or other charge with  respect to any Note,  Letter of
Credit or  Application  or shall change the basis of taxation of payments to any
of the Lenders (or any of their respective  Lending Offices) of the principal of
or interest on any Note,  Letter of Credit or  Application  or any other amounts
due under this Agreement in respect  thereof  (except for changes in the rate of
tax on the overall  net income of any of the Lenders or any of their  respective
Lending Offices imposed by the jurisdiction in which such Lender is organized or
is or should be qualified to do business or such Lending Office is located); or

     (ii)  shall  impose,  modify or deem  applicable  any  reserve  (including,
without limitation, any imposed by the Board of Governors of the Federal Reserve
System),  special deposit,  insurance or capital or similar  requirement against
assets of, deposits with or for the account of, or credit extended by any of the
Lenders (or any of their  respective  Lending Offices) or shall impose on any of
the Lenders (or any of their respective Lending Offices) or the foreign exchange
and interbank markets any other condition  affecting any Note; and the result of
any of the  foregoing  is to  increase  the  costs  to  any  of the  Lenders  of
maintaining any LIBOR Rate Loan or issuing or participating in Letters of Credit
or to reduce the yield or amount of any sum received or receivable by any of the
Lenders under this  Agreement or under the Notes in respect of a LIBOR Rate Loan
or Letter of Credit or  Application,  then such Lender shall promptly notify the
Administrative  Agent,  and the  Administrative  Agent shall promptly notify the
Borrowers of such fact and demand compensation therefor and, within fifteen (15)
days after such notice by the  Administrative  Agent, the Borrowers shall pay to
such Lender such additional  amount or amounts as will compensate such Lender or
Lenders for such  increased  cost or reduction.  The  Administrative  Agent will
promptly  notify the Borrowers of any event of which it has knowledge which will
entitle such Lender to compensation  pursuant to this Section 5.8(c);  provided,
that the Administrative Agent shall incur no liability whatsoever to the Lenders
or the Borrowers in the event it fails to do so. The amount of such compensation
shall be determined, in the applicable Lender's sole discretion,  based upon the
assumption  that such Lender funded its Commitment  Percentage of the LIBOR Rate
Loans in the London  interbank  market and using any  reasonable  attribution or
averaging  methods  which  such  Lender  deems  appropriate  and  practical.   A
certificate of such Lender setting forth the basis for  determining  such amount
or amounts  necessary  to  compensate  such  Lender  shall be  forwarded  to the
Borrowers through the Administrative Agent and shall be conclusively presumed to
be correct save for manifest error.

                                       39

     SECTION 5.9 Indemnity. The Borrowers  hereby indemnify each of the Lenders
against any loss or expense which may arise or be  attributable to each Lender's
obtaining,  liquidating or employing deposits or other funds acquired to effect,
fund or maintain any Loan (a) as a  consequence  of any failure by the Borrowers
to make any payment when due of any amount due  hereunder in  connection  with a
LIBOR Rate Loan,  (b) due to any  failure of the  Borrowers  to borrow on a date
specified therefor in a Notice of Borrowing or Notice of Continuation/Conversion
or (c) due to any payment,  prepayment or conversion of any LIBOR Rate Loan on a
date other than the last day of the Interest Period therefor. The amount of such
loss or expense shall be determined, in the applicable Lender's sole discretion,
based upon the assumption  that such Lender funded its Commitment  Percentage of
the LIBOR  Rate Loans in the London  interbank  market and using any  reasonable
attribution  or  averaging  methods  which such  Lender  deems  appropriate  and
practical.  A certificate of such Lender setting forth the basis for determining
such amount or amounts necessary to compensate such Lender shall be forwarded to
the  Borrowers  through  the  Administrative  Agent  and  shall be  conclusively
presumed to be correct save for manifest error.


     SECTION 5.10 Capital Requirements. If after the date hereof either (a) the
introduction of, or any change in, or in the  interpretation  of, any Applicable
Law or (b)  compliance  with any  guideline  or request from any central bank or
comparable  agency or other  Governmental  Authority  (whether or not having the
force of law),  has or would have the effect of  reducing  the rate of return on
the capital of, or has affected or would  affect the amount of capital  required
to be maintained by, any Lender or any corporation  controlling such Lender as a
consequence of, or with reference to the  Commitments  and other  commitments of
this type, below the rate which the Lender or such other  corporation could have
achieved but for such introduction,  change or compliance,  then within five (5)
Business Days after written demand by any such Lender,  the Borrowers  shall pay
to such Lender from time to time as specified by such Lender additional  amounts
sufficient to compensate such Lender or other corporation for such reduction.  A
certificate as to such amounts submitted to the Borrowers and the Administrative
Agent by such Lender, shall, in the absence of manifest error, be presumed to be
correct and binding for all purposes.

     SECTION 5.11 Taxes.

     (a)  Payments  Free  and  Clear.  Any and  all  payments  by the  Borrowers
hereunder  or under the Notes or the  Letters  of Credit  shall be made free and
clear of and without deduction for any and all present or future taxes,  levies,
imposts,  deductions,  charges or withholding,  and all liabilities with respect
thereto excluding,  (i) in the case of each Lender and the Administrative Agent,
income and franchise taxes imposed by the  jurisdiction  under the laws of which
such Lender or the Administrative  Agent (as the case may be) is organized or is
or should be qualified to do business or any political subdivision thereof, (ii)
in  the  case  of  each  Lender,  income  and  franchise  taxes  imposed  by the
jurisdiction  of such  Lender's  Lending  Office  or any  political  subdivision
thereof and (iii) any United  States  federal  income tax that is imposed on, or
required to be deducted from, a payment hereunder (or under the Notes or Letters
of  Credit) by reason of a failure to comply  with the  requirements  of Section
5.11(e) (all such non-excluded  taxes,  levies,  imposts,  deductions,  charges,
withholdings and liabilities being hereinafter  referred to as "Taxes").  If the
Borrowers shall be required by law to deduct any Taxes from or in respect of any
sum payable hereunder or under any Note or Letter of Credit to any Lender or the
Administrative Agent, (A) the sum payable shall be increased as may be necessary
so that after making all required deductions (including deductions applicable to
additional   sums  payable   under  this  Section   5.11)  such  Lender  or  the
Administrative Agent (as the case may be) receives an amount equal to the amount
such party  would  have  received  had no such  deductions  been  made,  (B) the
Borrowers  shall  make such  deductions,  (C) the  Borrowers  shall pay the full
amount  deducted  to  the  relevant  taxing  authority  or  other  authority  in
accordance  with  applicable  law, and (D) the  Borrowers  shall  deliver to the
Administrative  Agent evidence of such payment to the relevant taxing  authority
or other authority in the manner provided in Section 5.11(d).

     (b) Stamp and Other Taxes. In addition, the Borrowers shall pay any present
or future stamp,  registration,  recordation or  documentary  taxes or any other
similar fees or charges or excise or property taxes, levies of the United States
or  any  state  or  political  subdivision  thereof  or any  applicable  foreign
jurisdiction  which arise from any payment made hereunder or from the execution,
delivery or registration  of, or otherwise with respect to, this Agreement,  the
Loans, the Letters of Credit, the other Loan Documents, or the perfection of any
rights or  security  interest  in respect  thereto  (hereinafter  referred to as
"Other Taxes").

Administrative  Agent for the full amount of Taxes and Other  Taxes  (including,
without  limitation,  any Taxes and Other Taxes imposed by any  jurisdiction  on
amounts   payable   under  this  Section  5.11)  paid  by  such  Lender  or  the
Administrative  Agent  (as  the  case  may  be)  and  any  liability  (including
penalties,  interest and expenses)  arising  therefrom or with respect  thereto,
whether or not such Taxes or Other  Taxes were  correctly  or legally  asserted.
Such  indemnification  shall be made within  thirty (30) days from the date such
Lender or the  Administrative  Agent (as the case may be) makes  written  demand
therefor.

     (d)  Evidence  of  Payment.  Within  thirty (30) days after the date of any
payment  of  Taxes  or  Other  Taxes,   the  Borrowers   shall  furnish  to  the
Administrative  Agent, at its address  referred to in Section 14.1, the original
or a certified copy of a receipt evidencing payment thereof or other evidence of
payment satisfactory to the Administrative Agent.

jurisdiction  other than the United States or any state thereof shall deliver to
the Borrowers,  with a copy to the Administrative  Agent, on the Closing Date or

applicable,  (i) two United States Internal  Revenue Service Forms 4224 or Forms
1001, as applicable (or successor  forms)  properly  completed and certifying in
each case that such Lender is entitled to a complete  exemption from withholding
or deduction for or on account of any United States  federal  income taxes,  and
(ii) an Internal  Revenue Service Form W-8 or W-9 or successor  applicable form,
as the  case may be,  to  establish  an  exemption  from  United  States  backup
withholding  taxes. Each such Lender further agrees to deliver to the Borrowers,
with a copy to the  Administrative  Agent,  a Form  1001 or 4224 and Form W-8 or
W-9, or successor  applicable forms or manner of certification,  as the case may
be, on or before  the date that any such form  expires or  becomes  obsolete  or
after the  occurrence  of any event  requiring  a change in the most recent form
previously  delivered by it to the  Borrowers,  certifying in the case of a Form
1001 or 4224 that  such  Lender is  entitled  to  receive  payments  under  this
Agreement  without  deduction or withholding of any United States federal income
taxes (unless in any such case an event (including without limitation any change
in treaty,  law or regulation)  has occurred prior to the date on which any such
delivery would  otherwise be required which renders such forms  inapplicable  or
the exemption to which such forms relate  unavailable  and such Lender  notifies
the  Borrowers and the  Administrative  Agent that it is not entitled to receive
payments without deduction or withholding of United States federal income taxes)
and, in the case of a Form W-8 or W-9,  establishing  an  exemption  from United

the  Borrowers  hereunder,  the  agreements  and  obligations  of the  Borrowers

Obligations and the termination of the Commitments.

as provided in the Security Documents.

     SECTION 7.1  Representations  and Warranties.  To induce the Administrative
Agent and Lenders to enter into this Agreement and to induce the Lenders to make
Extensions  of Credit,  each  Borrower  hereby  represents  and  warrants to the
Administrative  Agent and  Lenders  both before and after  giving  effect to the
transactions    contemplated   hereunder   that:   

     (a) Organization;  Power; Qualification.  Each Borrower and each Subsidiary
(including DuraTherm,  Inc.) thereof is duly organized,  validly existing and in
good  standing  under  the  laws of the  jurisdiction  of its  incorporation  or
formation, has the power and authority to own its properties and to carry on its
business  as now  being  and  hereafter  proposed  to be  conducted  and is duly
qualified  and  authorized  to do  business  in each  jurisdiction  in which the
character  of  its  properties  or the  nature  of its  business  requires  such
qualification and  authorization,  except where the failure to be duly qualified
and authorized will not have a Material  Adverse Effect.  The  jurisdictions  in
which each Borrower and each Subsidiary (including DuraTherm,  Inc.) thereof are
organized  and  qualified to do business as of the Closing Date are described on
Schedule 7.1(a).

     (b) Ownership. Each Subsidiary (including DuraTherm, Inc.) of each Borrower
as of the Closing Date is listed on Schedule 7.1(b). As of the Closing Date, the
capitalization  of each  Borrower and each  Subsidiary  thereof  consists of the
number of  shares,  authorized,  issued and  outstanding,  of such  classes  and

shares  have been duly  authorized  and  validly  issued  and are fully paid and
nonassessable.  The shareholders of the Subsidiaries (including DuraTherm, Inc.)
of each  Borrower  and the number of shares owned by each as of the Closing Date
are  described  on  Schedule  7.1(b).  As of  the  Closing  Date,  there  are no
outstanding  stock  purchase  warrants,   subscriptions,   options,  securities,

issuance  of  capital  stock  of  any  Borrower  or  any  Subsidiary  (including
DuraTherm, Inc.) thereof, except as described on Schedule 7.1(b).

     (c) Authorization of Agreement, Loan Documents and Borrowing. Each Borrower
and each Subsidiary thereof has the right, power and authority and has taken all
necessary  corporate and other action to authorize the  execution,  delivery and
performance  of this  Agreement and each of the other Loan Documents to which it
is a party in accordance with their respective terms. This Agreement and each of
the other Loan  Documents  have been duly  executed  and  delivered  by the duly
authorized officers of each Borrower and each of its Subsidiaries party thereto,
and each such document  constitutes the legal,  valid and binding  obligation of
each Borrower or its Subsidiary  party thereto,  enforceable in accordance  with
its terms, except as such enforcement may be limited by bankruptcy,  insolvency,
reorganization,  moratorium or similar state or federal  debtor relief laws from
time to time in effect  which affect the  enforcement  of  creditors'  rights in
general and the availability of equitable remedies.

     (d) Compliance of Agreement,  Loan Documents and Borrowing with Laws,  Etc.
The execution,  delivery and  performance  by each Borrower and each  Subsidiary
thereof  of the Loan  Documents  to  which  each  such  Person  is a  party,  in
accordance  with  their  respective  terms,  the  borrowings  hereunder  and the
transactions  contemplated  hereby do not and will not,  by the passage of time,
the giving of notice or  otherwise,  (i)  require any  Governmental  Approval or
violate any Applicable  Law relating to any Borrower or any Subsidiary  thereof,
(ii)  conflict  with,  result in a breach of or  constitute a default  under the
articles  of  incorporation,  bylaws or other  organizational  documents  of any
Borrower  or  any  Subsidiary  thereof  or any  indenture,  agreement  or  other
instrument to which such Person is a party or by which any of its properties may
be bound or any Governmental  Approval  relating to such Person, or (iii) result
in or require the creation or imposition of any Lien upon or with respect to any
property now owned or hereafter acquired by such Person other than Liens arising
under the Loan Documents.

                                       47
<PAGE>

     (e) Compliance  with Law;  Governmental  Approvals.  Each Borrower and each
Subsidiary  (including  DuraTherm,   Inc.)  thereof  (i)  has  all  Governmental
Approvals required by any Applicable Law for it to conduct its business, each of
which is in full force and effect,  is final and not subject to review on appeal
and is not  the  subject  of any  pending  or,  to the  best  of its  knowledge,
threatened attack by direct or collateral proceeding,  and (ii) is in compliance
with each  Governmental  Approval  applicable to it and in  compliance  with all
other  Applicable  Laws relating to it or any of its respective  properties,  in
each case  except to the extent that any such lack of  Governmental  Approval or
failure to comply would not have a Material Adverse Effect.

     (f) Tax Returns and Payments.  Each Borrower and each Subsidiary (including
DuraTherm,  Inc.)  thereof  has duly  filed or caused  to be filed all  federal,
state,  material  local and other tax returns  required by Applicable  Law to be
filed, and has paid, or made adequate provision for the payment of, all federal,
state,  local and other taxes,  assessments and  governmental  charges or levies
upon it and its property,  income, profits and assets which are due and payable.
No  Governmental  Authority  has  asserted  any Lien or other claim  against any
Borrower or  Subsidiary  (including  DuraTherm,  Inc.)  thereof  with respect to
unpaid taxes which has not been  discharged or resolved.  The charges,  accruals
and  reserves  on the  books of each  Borrower  and each  Subsidiary  (including
DuraTherm,  Inc.) thereof in respect of federal, state, material local and other
taxes for all Fiscal Years and portions  thereof since the  organization of such
Borrower and each  Subsidiary  (including  DuraTherm,  Inc.)  thereof are in the
judgment  of each  such  Borrower  adequate,  and each  such  Borrower  does not
anticipate any additional taxes or assessments for any of such years.

     (g)  Intellectual  Property  Matters.  Each  Borrower  and each  Subsidiary
thereof owns or possesses  rights to use all franchises,  licenses,  copyrights,
copyright applications, patents, patent rights or licenses, patent applications,
trademarks,  trademark rights,  trade names,  trade name rights,  copyrights and
rights with respect to the foregoing which are required to conduct its business.
No event has occurred  which  permits,  or after notice or lapse of time or both
would permit,  the revocation or termination of any such rights, and no Borrower
nor any  Subsidiary  thereof  is liable to any  Person  for  infringement  under
Applicable  Law with  respect  to any such  rights as a result  of its  business
operations.

     (h)  Environmental  Matters.  In the ordinary course of its business,  each
Borrower  conducts an ongoing review of the effect of Environmental  Laws on the
business,  operations and properties of such Borrower and its  Subsidiaries,  in
the course of which it identifies and evaluates associated liabilities and costs
(including,  without limitation,  any capital or operating expenditures required
for clean-up or closure of properties presently or previously owned, any capital
or  operating  expenditures  required  to achieve or  maintain  compliance  with
environmental  protection  standards  imposed  by law or as a  condition  of any
license,  permit or contract,  any related constraints on operating  activities,
including any periodic or permanent shutdown of any facility or reduction in the
level of or change in the nature of operations  conducted at any such  facility,
any costs or  liabilities  in  connection  with  off-site  disposal of wastes or
Hazardous Substances,  and any actual or potential liabilities to third parties,
including employees,  and any related costs and expenses).  On the basis of this
review, each Borrower has concluded that such associated  liabilities and costs,
including the costs of compliance with Environmental  Laws, could not reasonably
be expected to have a Material Adverse Effect.

     (i) ERISA.

by the Internal  Revenue  Service to be so qualified,  and each trust related to

Pension  Plan,  nor has any Borrower or any ERISA  Affiliate  failed to make any
contributions  or to pay any amounts due and owing as required by Section 412 of

ERISA,  nor has there been any event  requiring  any  disclosure  under  Section
4041(c)(3)(C) or 4063(a) of ERISA with respect to any Pension Plan;

     (iv) No Borrower  nor any ERISA  Affiliate  has: (A) engaged in a nonexempt

     (j)  Margin  Stock.  No  Borrower  nor any  Subsidiary  thereof  is engaged
principally or as one of its activities in the business of extending  credit for
the purpose of  "purchasing" or "carrying" any "margin stock" (as each such term
is defined or used in  Regulation  U of the Board of  Governors  of the  Federal
Reserve  System).  No part of the  proceeds  of any of the Loans or  Letters  of
Credit will be used for  purchasing or carrying  margin stock or for any purpose
which  violates,  or  which  would  be  inconsistent  with,  the  provisions  of
Regulation T, U or X of such Board of Governors.

     (k) Government  Regulation.  No Borrower nor any  Subsidiary  thereof is an
"investment  company" or a company  "controlled" by an "investment  company" (as
each such term is  defined or used in the  Investment  Company  Act of 1940,  as
amended) and no Borrower nor any  Subsidiary  thereof is, or after giving effect
to any  Extension  of Credit  will be,  subject to  regulation  under the Public
Utility  Holding  Company Act of 1935 or the  Interstate  Commerce  Act, each as
amended,  or any other  Applicable  Law which  limits  its  ability  to incur or
consummate the transactions contemplated hereby.

list of all Material Contracts of the Borrowers and their Subsidiaries in effect
as of the Closing Date not listed on any other  Schedule  hereto;  other than as

effect  to  the  consummation  of the  transactions  contemplated  by  the  Loan
Documents  will be,  in full  force  and  effect  in  accordance  with the terms
thereof.  The Borrowers and their  Subsidiaries have delivered or made available

stable  work force in place and is not,  as of the  Closing  Date,  party to any
collective  bargaining  agreement nor has any labor union been recognized as the
representative  of its  employees  except as set forth on  Schedule  7.1(m).  No
Borrower knows of any pending, threatened or contemplated strikes, work stoppage
or other  collective  labor  disputes  involving  its  employees or those of its
Subsidiaries, which would have a Material Adverse Effect.

the Borrowers and their Subsidiaries (including DuraTherm, Inc.) as of September

present the assets,  liabilities  and  financial  position of the  Borrowers and
their Subsidiaries (including DuraTherm, Inc.) as at such dates, and the results
of the operations and changes of financial  position for the periods then ended.
All such  financial  statements,  including  the  related  schedules  and  notes
thereto,  have been prepared in accordance with GAAP,  except in the case of the
unaudited financial  statements referred to above, for the omission of footnotes
and  ordinary  year end  adjustments).  The  Borrowers  and  their  Subsidiaries
(including DuraTherm, Inc.) have no Debt, obligation or other unusual forward or
long-term  commitment  which is not  reflected  in  accordance  with GAAP in the

DuraTherm,  Inc.) taken as a whole and no event has occurred or condition arisen
that could reasonably be expected to have a Material  Adverse Effect,  except as

such title to the real property  owned by it as is necessary or desirable to the
conduct  of its  business  and  valid  and  legal  title to all of its  personal
property  and assets,  including,  but not limited to,  those  reflected  on the
balance  sheets of the Borrowers and their  Subsidiaries  delivered  pursuant to
Section 7.1(o),  except those which have been disposed of by any Borrower or any
Subsidiary  thereof  subsequent to such date which dispositions have been in the
ordinary course of business or as otherwise expressly permitted hereunder.

     (r)  Liens.  None of the  properties  and  assets  of any  Borrower  or any
Subsidiary  thereof is subject to any Lien, except Permitted Liens. No financing
statement  under  the  Uniform  Commercial  Code of any  state  which  names any
Borrower or any  Subsidiary  thereof or any of their  respective  trade names or
divisions  as debtor  and which has not been  terminated,  has been filed in any
state or other  jurisdiction  and no  Borrower  nor any  Subsidiary  thereof has
signed any such financing  statement or any security  agreement  authorizing any
secured party thereunder to file any such financing statement, except to perfect

thereof have performed and are in compliance  with all of the terms of such Debt
and Guaranty  Obligations and all instruments and agreements  relating  thereto,
and no default or event of default,  or event or condition  which with notice or

part of any  Borrower or any  Subsidiary  (including  DuraTherm,  Inc.)  thereof
exists with respect to any such Debt or Guaranty Obligation.

     (t)  Litigation.  Except for matters  existing on the Closing  Date and set
forth on Schedule  7.1(t),  there are no actions,  suits or proceedings  pending
nor, to the  knowledge of any Borrower,  threatened  against or in any other way
relating  adversely to or affecting  any Borrower or any  Subsidiary  (including
DuraTherm,  Inc.) thereof or any of their respective  properties in any court or
before any  arbitrator  of any kind or before or by any  Governmental  Authority
which, if adversely  determined  could reasonably be expected to have a Material
Adverse Effect,  and which are reasonably  likely to be determined  adversely to
the Borrower or such Subsidiary.

                                       51
<PAGE>

     (u)  Absence of  Defaults.  No event has  occurred or is  continuing  which
constitutes a Default or an Event of Default.

     (v)  Accounts.  Each  Account  shown  on the  most  recent  Borrowing  Base
Certificate is, as of the date of the Borrowing Base  Certificate,  qualified to
be in the Borrowing Base.

     (w) Year 2000.

     (i) As of the Closing Date, each Borrower and each  Subsidiary  thereof (A)
has  initiated  a  review  and  assessment  of all  areas  of its  business  and
operations  (including those affected by information received from suppliers and
vendors)  that  may be  adversely  affected  by a Year  2000  Problem,  (B)  has
developed  or is in the  process of  developing  a  comprehensive  and  detailed
strategic  plan to address its Year 2000 Problem,  if any, and will, on a timely
basis (but in no event later than  September 30, 1999),  implement such plan and
(C) reasonably believes that the necessary  expenditure of capital and resources
to eliminate  any such Year 2000  Problem will not result in a Material  Adverse
Effect.

     (ii) As of the Closing Date, to the best knowledge of each Borrower  (after
due inquiry),  each material supplier,  vendor and customer of such Borrower and
each Subsidiary of such Borrower thereof will on a timely basis  eliminate,  its
Year 2000 Problem.

     (iii) "Year 2000  Problem"  shall  mean,  with  respect to any Person,  the
possibility that the computer  applications  and software  programs used by such
Person in the  operation of its business will be unable to  effectively  process
data including data fields requiring references to dates on and after January 1,
2000,  and may  experience or produce  invalid or incorrect  results or abnormal
operation related to or as a result of the occurrence of such dates.

     (x) Accuracy and  Completeness  of  Information.  All written  information,
reports and other papers and data other than financial  projections  produced by
or on behalf of each Borrower and each Subsidiary  (including  DuraTherm,  Inc.)
thereof  and  furnished  to the  Lenders  were,  at the time  the  same  were so
furnished, complete and correct in all material respects to the extent necessary
to give the recipient a true and accurate  knowledge of the subject  matter.  No
document furnished or written statement other than financial projections made to
the  Administrative  Agent or the  Lenders  by any  Borrower  or any  Subsidiary
(including  DuraTherm,   Inc.)  thereof  in  connection  with  the  negotiation,
preparation or execution of this Agreement or any of the Loan Documents contains
or will contain any untrue statement of a fact material to the  creditworthiness
of any Borrower or any Subsidiary (including  DuraTherm,  Inc.) thereof or omits
or will omit to state a material fact  necessary in order to make the statements
contained therein not misleading. No Borrower is aware of any facts which it has
not disclosed in writing to the  Administrative  Agent having a Material Adverse
Effect, or insofar as any Borrower can now foresee, could reasonably be expected
to have a Material Adverse Effect.

                                       52

representations   and   warranties  set  forth  in  this  Article  VII  and  all

     SECTION 12.2 Remedies. Upon the occurrence and during the  continuation of
an  Event  of  Default,   with  the  consent  of  the  Required   Lenders,   the
Administrative  Agent may,  or upon the  request of the  Required  Lenders,  the
Administrative Agent shall, by notice to the Borrowers:

     (a) Acceleration;  Termination of Facilities.  Declare the principal of and
interest on the Loans, the Notes and the  Reimbursement  Obligations at the time
outstanding, and all other amounts owed to the Lenders and to the Administrative
Agent under this  Agreement or any of the other Loan  Documents  (other than any
Hedging Agreement) (including, without limitation, all L/C Obligations,  whether
or not the  beneficiaries of the then  outstanding  Letters of Credit shall have
presented the documents  required  thereunder) and all other Obligations  (other
than  obligations  owing under any Hedging  Agreement),  to be forthwith due and
payable,  whereupon the same shall  immediately  become due and payable  without
presentment,  demand,  protest  or other  notice of any  kind,  all of which are
expressly waived,  anything in this Agreement or the other Loan Documents to the
contrary notwithstanding, and terminate the Credit Facility and any right of the
Borrowers to request borrowings or Letters of Credit thereunder;  provided, that
upon the occurrence of an Event of Default  specified in Section 12.1(j) or (k),
the Credit Facility shall be automatically terminated and all Obligations (other
than obligations owing under any Hedging Agreement) shall  automatically  become
due and payable.

     (b) Letters of Credit.  With  respect to all Letters of Credit with respect

acceleration pursuant to the preceding paragraph,  require the Borrowers at such
time to deposit in a cash collateral account opened by the Administrative  Agent
an amount  equal to the  aggregate  then  undrawn and  unexpired  amount of such
Letters of Credit. Amounts held in such cash collateral account shall be applied
by the Administrative Agent to the payment of drafts drawn under such Letters of
Credit,  and the unused  portion  thereof after all such Letters of Credit shall
have  expired or been fully  drawn upon,  if any,  shall be applied to repay the
other  Obligations.  After all such Letters of Credit shall have expired or been
fully drawn upon, the Reimbursement Obligation shall have been satisfied and all
other  Obligations  shall have been paid in full,  the balance,  if any, in such
cash collateral account shall be returned to the Borrowers.

                                       72
<PAGE>

     (c) Rights of  Collection.  Exercise  on behalf of the  Lenders  all of its
other rights and remedies  under this  Agreement,  the other Loan  Documents and
Applicable Law, in order to satisfy all of the Obligations of the Borrowers.

     SECTION  12.3  Rights  and  Remedies  Cumulative;  Non-Waiver;  etc.  The
enumeration  of the  rights and  remedies  of the  Administrative  Agent and the
Lenders set forth in this  Agreement  is not intended to be  exhaustive  and the
exercise  by the  Administrative  Agent and the  Lenders  of any right or remedy
shall not preclude  the  exercise of any other rights or remedies,  all of which
shall be cumulative, and shall be in addition to any other right or remedy given
hereunder or under the Loan Documents or that may now or hereafter  exist in law
or in equity or by suit or otherwise.  No delay or failure to take action on the
part of the Administrative Agent or any Lender in exercising any right, power or
privilege  shall  operate as a waiver  thereof,  nor shall any single or partial
exercise  of any  such  right,  power or  privilege  preclude  other or  further
exercise thereof or the exercise of any other right, power or privilege or shall
be  construed  to be a waiver of any  Event of  Default.  No  course of  dealing
between  the  Borrowers,  the  Administrative  Agent  and the  Lenders  or their
respective agents or employees shall be effective to change, modify or discharge
any  provision  of this  Agreement  or any of the  other  Loan  Documents  or to
constitute a waiver of any Event of Default.


                                  ARTICLE XIII

                  THE ADMINISTRATIVE AGENT AND COLLATERAL AGENT

     SECTION  13.1  Appointment.  Each  of  the  Lenders  hereby   irrevocably
designates  and appoints First Union as  Administrative  Agent and as Collateral
Agent of such  Lender,  in each case,  under this  Agreement  and the other Loan
Documents for the term hereof and each such Lender  irrevocably  authorizes each
of First Union as Administrative  Agent and as Collateral Agent for such Lender,
to take such action on its behalf under the provisions of this Agreement and the
other Loan  Documents and to exercise such powers and perform such duties as are
expressly  delegated to such Agent by the terms of this Agreement and such other
Loan  Documents,  together with such other powers as are  reasonably  incidental
thereto.  Notwithstanding  any  provision  to the  contrary  elsewhere  in  this
Agreement or such other Loan  Documents,  neither Agent shall have any duties or
responsibilities,  except those  expressly set forth herein and therein,  or any
fiduciary  relationship with any Lender,  and no implied  covenants,  functions,
responsibilities,  duties,  obligations or  liabilities  shall be read into this
Agreement or the other Loan Documents or otherwise exist against any Agent.  Any
reference  to the  Agent in this  Article  XIII  shall be deemed to refer to the
Administrative Agent or Collateral Agent, as applicable,  solely in its capacity
as  Administrative  Agent or Collateral  Agent,  as  applicable,  and not in its
capacity as a Lender.

                                       73
<PAGE>

     SECTION  13.2  Delegation of Duties. The Agents may  execute any of their
respective  duties  under  this  Agreement  and the other Loan  Documents  by or
through agents or  attorneys-in-fact  and shall be entitled to advice of counsel
concerning all matters  pertaining to such duties. No Agent shall be responsible
for the negligence or misconduct of any agents or attorneys-in-fact  selected by
such Agent with reasonable care.

     SECTION 13.3 Exculpatory Provisions. Neither Agent nor any of such Agent's
officers,  directors,  employees,  agents,  attorneys-in-fact,  Subsidiaries  or
Affiliates  shall be (a) liable for any action  lawfully  taken or omitted to be
taken by it or such Person  under or in  connection  with this  Agreement or the
other  Loan  Documents  (except  for  actions  occasioned  solely by its or such
Person's own gross negligence or willful misconduct),  or (b) responsible in any
manner to any of the Lenders for any recitals,  statements,  representations  or
warranties made by any Borrower or any Subsidiary thereof or any officer thereof
contained in this Agreement or the other Loan  Documents or in any  certificate,
report,  statement or other document referred to or provided for in, or received
by such Agent under or in  connection  with,  this  Agreement  or the other Loan
Documents or for the value, validity, effectiveness, genuineness, enforceability
or  sufficiency of this Agreement or the other Loan Documents or for any failure
of any Borrower or any Subsidiary  thereof to perform its obligations  hereunder
or thereunder. No Agent shall be under any obligation to any Lender to ascertain
or to inquire  as to the  observance  or  performance  of any of the  agreements
contained in, or conditions of, this  Agreement,  or to inspect the  properties,
books or records of the Borrowers or any of their Subsidiaries.

     SECTION 13.4 Reliance by the Agents. The Agents shall be entitled to rely,
and shall be fully  protected in relying,  upon any note,  writing,  resolution,
notice, consent, certificate,  affidavit, letter, cablegram, telegram, telecopy,
telex or teletype  message,  statement,  order or other document or conversation
believed by such Agent to be genuine and correct and to have been  signed,  sent
or made by the proper Person or Persons and upon advice and  statements of legal
counsel (including, without limitation,  counsel to the Borrowers),  independent
accountants  and other experts  selected by such Agent.  The Agents may deem and
treat the payee of any Note as the owner  thereof for all  purposes  unless such
Note shall have been  transferred in accordance  with Section 14.10 hereof.  The
Agents shall be fully  justified in failing or refusing to take any action under
this  Agreement  and the other Loan  Documents  unless  such Agent  shall  first
receive such advice or concurrence  of the Required  Lenders (or, when expressly
required  hereby or by the relevant other Loan Document,  all the Lenders) as it
deems  appropriate or it shall first be indemnified to its  satisfaction  by the
Lenders against any and all liability and expense which may be incurred by it by
reason of taking or  continuing to take any such action except for its own gross
negligence  or  willful  misconduct.  The  Agents  shall  in all  cases be fully
protected in acting, or in refraining from acting,  under this Agreement and the
Notes in accordance  with a request of the Required  Lenders (or, when expressly
required  hereby,  all the  Lenders),  and such  request and any action taken or
failure to act  pursuant  thereto  shall be binding upon all the Lenders and all
future holders of the Notes.

                                       74
<PAGE>

     SECTION 13.5 Notice of Default. No Agent shall be deemed to have knowledge
or notice of the occurrence of any Default or Event of Default  hereunder unless
it has  received  notice  from a  Lender  or the  Borrowers  referring  to  this
Agreement,  describing  such  Default or Event of Default and stating  that such
notice is a "notice of  default".  In the event that any Agent  receives  such a
notice,  it shall  promptly  give  notice  thereof to the other Agent and to the
Lenders. The Agents shall take such action with respect to such Default or Event
of Default as shall be  reasonably  directed by the Required  Lenders;  provided
that unless and until such Agent shall have received such directions, such Agent
may (but shall not be  obligated  to) take such  action,  or refrain from taking
such  action,  with respect to such Default or Event of Default as it shall deem
advisable in the best interests of the Lenders,  except to the extent that other
provisions of this Agreement  expressly require that any such action be taken or
not be taken  only with the  consent  and  authorization  or the  request of the
Lenders or Required Lenders, as applicable.

     SECTION  13.6  Non-Reliance on the Agents and Other Lenders. Each Lender
expressly  acknowledges  that neither  Agent nor any of such  Agent's  officers,
directors, employees, agents, attorneys-in-fact,  Subsidiaries or Affiliates has
made  any  representations  or  warranties  to it and  that no act by any  Agent
hereinafter  taken,  including any review of the affairs of the Borrowers or any
of their  Subsidiaries,  shall be deemed to  constitute  any  representation  or
warranty by such Agent to any Lender.  Each Lender represents to each Agent that
it has,  independently  and without reliance upon any Agent or any other Lender,
and based on such documents and information as it has deemed  appropriate,  made
its own appraisal of and investigation into the business, operations,  property,
financial and other  condition and  creditworthiness  of the Borrowers and their
Subsidiaries  and  made  its own  decision  to  make  its  Loans  and  issue  or
participate in Letter of Credit  hereunder and enter into this  Agreement.  Each
Lender also represents that it will, independently and without reliance upon any
Agent or any other Lender,  and based on such  documents and  information  as it
shall deem  appropriate at the time,  continue to make its own credit  analysis,
appraisals and decisions in taking or not taking action under this Agreement and
the other Loan Documents,  and to make such  investigation as it deems necessary
to inform itself as to the business,  operations,  property, financial and other
condition and  creditworthiness of the Borrowers and their Subsidiaries.  Except
for notices,  reports and other documents  expressly required to be furnished to
the Lenders by an Agent hereunder or by the other Loan Documents, no Agent shall
have any duty or  responsibility  to provide any Lender with any credit or other
information concerning the business,  operations,  property, financial and other
condition or  creditworthiness  of the  Borrowers  or any of their  Subsidiaries
which  may  come  into the  possession  of any  Agent  or any of its  respective
officers,  directors,  employees,  agents,  attorneys-in-fact,  Subsidiaries  or
Affiliates.

     SECTION 13.7  Indemnification. The Lenders agree to indemnify each of the
Administrative Agent and Collateral Agent in its respective capacity as such and
(to the  extent  not  reimbursed  by the  Borrowers  and  without  limiting  the
obligation  of the  Borrowers to do so),  ratably  according  to the  respective
amounts  of  their  Commitment  Percentages,   from  and  against  any  and  all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs,  expenses or  disbursements  of any kind whatsoever which may at any time
(including,  without limitation,  at any time following the payment of the Notes
or any Reimbursement  Obligation) be imposed on, incurred by or asserted against
any Agent in any way  relating to or arising out of this  Agreement or the other
Loan  Documents,  or any  documents  contemplated  by or  referred  to herein or
therein or the transactions  contemplated  hereby or thereby or any action taken
or  omitted  by any  Agent  under or in  connection  with any of the  foregoing;
provided  that no Lender  shall be liable for the payment of any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs,  expenses or disbursements  resulting solely from such Agent's bad faith,
gross  negligence  or willful  misconduct.  The  agreements in this Section 13.7
shall survive the payment of the Notes,  any  Reimbursement  Obligation  and all
other amounts payable hereunder and the termination of this Agreement.

                                       75
<PAGE>

     SECTION 13.8 The Agents in Their  Individual  Capacity. Each Agent and its
respective  Subsidiaries  and Affiliates may make loans to, accept deposits from
and  generally  engage in any kind of business with the Borrowers as though such
Agent were not an Agent hereunder.  With respect to any Loans made or renewed by
it and any Note issued to it and with respect to any Letter of Credit  issued by
it or  participated  in by it,  such Agent shall have the same rights and powers
under this Agreement and the other Loan Documents as any Lender and may exercise
the same as though it were not an Agent,  and the terms  "Lender" and  "Lenders"
shall include the Agent in its individual capacity, if applicable.

     SECTION 13.9  Resignation of the Agents;  Successor Agents. Subject to the
appointment  and  acceptance  of a successor  as provided  below,  any Agent may
resign at any time by giving  notice  thereof to the Lenders and the  Borrowers.
Upon any such resignation,  the Required Lenders shall have the right to appoint
a successor Agent,  which successor shall have minimum capital and surplus of at
least  $500,000,000.  If no successor  Agent shall have been so appointed by the
Required  Lenders and shall have  accepted such  appointment  within thirty (30)
days after such Agent's giving of notice of resignation, then such Agent may, on
behalf of the Lenders,  appoint a successor  Agent,  which  successor shall have
minimum capital and surplus of at least $500,000,000. Upon the acceptance of any
appointment as Agent hereunder by a successor Agent,  such successor Agent shall
thereupon succeed to and become vested with all rights,  powers,  privileges and
duties of the retiring  Agent,  and the retiring Agent shall be discharged  from
its duties and obligations  hereunder.  After any retiring  Agent's  resignation
hereunder as Agent, the provisions of this Section 13.9 shall continue in effect
for its  benefit in respect  of any  actions  taken or omitted to be taken by it
while it was acting as 946808354946808430Agent946808430.

     (a)  Method  of  Communication.   Except  as  otherwise  provided  in  this
Agreement,  all notices and communications  hereunder shall be in writing, or by
telephone  subsequently  confirmed in writing.  Any notice shall be effective if
delivered by hand delivery or sent via telecopy,  recognized  overnight  courier
service or certified mail, return receipt requested, and shall be presumed to be

courier  service and (iii) on the third  Business Day following the date sent by
certified  mail,   return  receipt   requested.   A  telephonic  notice  to  the
Administrative Agent as understood by the Administrative Agent will be deemed to
be the  controlling  and  proper  notice in the event of a  discrepancy  with or
failure to receive a confirming written notice.

     SECTION 14.6 Binding Arbitration; Waiver of Jury Trial.

     (a) Binding  Arbitration.  Upon demand of any party, whether made before or
after institution of any judicial proceeding,  any dispute, claim or controversy
arising  out of,  connected  with or  relating  to the Notes or any  other  Loan
Documents ("Disputes"),  between or among parties to the Notes or any other Loan
Document  shall  be  resolved  by  binding   arbitration  as  provided   herein.
Institution of a judicial proceeding by a party does not waive the right of that
party to demand arbitration hereunder. Disputes may include, without limitation,
tort claims, counterclaims, claims brought as class actions, claims arising from
Loan  Documents  executed  in the  future,  disputes  as to  whether a matter is
subject to arbitration,  or claims concerning any aspect of the past, present or
future  relationships  arising  out of or  connected  with the  Loan  Documents.
Arbitration  shall be conducted  under and governed by the Commercial  Financial
Disputes Arbitration Rules (the "Arbitration Rules") of the American Arbitration
Association  and Title 9 of the U.S.  Code.  All  arbitration  hearings shall be
conducted in Charlotte,  North Carolina.  The expedited  procedures set forth in
Rule 51, et seq. of the Arbitration  Rules shall be applicable to claims of less
than  $1,000,000.  All  applicable  statutes  of  limitation  shall apply to any
Dispute.  A  judgment  upon  the  award  may  be  entered  in any  court  having
jurisdiction.   Notwithstanding   anything   foregoing  to  the  contrary,   any
arbitration  proceeding  demanded  hereunder shall begin within ninety (90) days
after such demand thereof and shall be concluded within one hundred twenty (120)
days after such  demand.  These time  limitations  may not be extended  unless a
party hereto shows cause for extension and then such extension  shall not exceed
a total of sixty (60) days.  The panel from which all  arbitrators  are selected
shall be comprised of licensed  attorneys.  The single  arbitrator  selected for
expedited  procedure  shall be a retired judge from the highest court of general
jurisdiction,  state  or  federal,  of the  state  where  the  hearing  will  be
conducted.  The  parties  hereto do not waive any  applicable  Federal  or state
substantive law except as provided herein.  Notwithstanding the foregoing,  this
paragraph shall not apply to any Hedging Agreement that is a Loan Document.

     (b) Jury Trial. THE ADMINISTRATIVE AGENT, THE COLLATERAL AGENT, EACH LENDER
AND EACH BORROWER  HEREBY  ACKNOWLEDGE  THAT BY AGREEING TO BINDING  ARBITRATION
THEY HAVE  IRREVOCABLY  WAIVED  THEIR  RESPECTIVE  RIGHTS TO A JURY  TRIAL  WITH
RESPECT TO ANY ACTION,  CLAIM OR OTHER PROCEEDING  ARISING OUT OF ANY DISPUTE IN
CONNECTION  WITH THIS  AGREEMENT,  THE NOTES OR THE OTHER  LOAN  DOCUMENTS,  ANY
RIGHTS OR OBLIGATIONS HEREUNDER OR THEREUNDER, OR THE PERFORMANCE OF SUCH RIGHTS
AND OBLIGATIONS.

                                       79
<PAGE>

     (c) Preservation of Certain Remedies. Notwithstanding the preceding binding
arbitration  provisions,  the  parties  hereto  and  the  other  Loan  Documents
preserve,  without diminution,  certain remedies that such Persons may employ or
exercise  freely,  either alone, in conjunction  with or during a Dispute.  Each
such Person shall have and hereby  reserves the right to proceed in any court of
proper  jurisdiction  or by self help to exercise  or  prosecute  the  following
remedies:  (i) all rights to foreclose  against any real or personal property or
other  security by  exercising a power of sale granted in the Loan  Documents or
under  applicable law or by judicial  foreclosure  and sale,  (ii) all rights of
self help including peaceful occupation of property and collection of rents, set
off, and  peaceful  possession  of  property,  (iii)  obtaining  provisional  or
ancillary remedies  including  injunctive  relief,  sequestration,  garnishment,
attachment,  appointment  of receiver  and in filing an  involuntary  bankruptcy
proceeding,  and (iv) when  applicable,  a judgment by  confession  of judgment.
Preservation  of these  remedies  does not limit the power of an  arbitrator  to
grant similar remedies that may be requested by a party in a Dispute.

     SECTION  14.7  Reversal  of Payments. To the extent any  Borrower  makes a
payment or payments  to any Agent for the ratable  benefit of the Lenders or any
Agent  receives  any  payment or proceeds of the  collateral  which  payments or
proceeds  or any part  thereof  are  subsequently  invalidated,  declared  to be
fraudulent or preferential, set aside and/or required to be repaid to a trustee,
receiver or any other  party under any  bankruptcy  law,  state or federal  law,
common law or equitable  cause,  then, to the extent of such payment or proceeds
repaid,  the  Obligations  or part  thereof  intended to be  satisfied  shall be
revived and  continued  in full force and effect as if such  payment or proceeds
had not been received by such Agent.

     SECTION 14.8 Injunctive Relief; Punitive Damages.

     (a) The  Borrowers  recognize  that,  in the event any  Borrowers  fails to
perform,  observe or discharge any of its obligations or liabilities  under this
Agreement,  any remedy of law may prove to be inadequate  relief to the Lenders.
Therefore,  each Borrower agrees that the Lenders, at the Lenders' option, shall
be  entitled  to  temporary  and  permanent  injunctive  relief in any such case
without the necessity of proving actual damages.

     (b) Each Agent,  each Lender and each Borrower (on behalf of itself and its
Subsidiaries)  hereby  agree that no such Person shall have a remedy of punitive
or exemplary  damages  against any other party to a Loan  Document and each such
Person  hereby  waives any right or claim to punitive or exemplary  damages that
they may now have or may arise in the  future in  connection  with any  Dispute,
whether such Dispute is resolved through arbitration or judicially.

     (c) The  parties  agree  that they shall not have a remedy of  punitive  or
exemplary  damages  against any other party in any Dispute and hereby  waive any
right or claim to punitive or exemplary damages they have now or which may arise
in the future in connection  with any Dispute whether the Dispute is resolved by
arbitration or judicially.

     SECTION  14.9   Accounting   Matters.  All   financial   and   accounting
calculations,  measurements  and  computations  made for any purpose relating to
this Agreement,  including, without limitation, all computations utilized by any
Borrower or any  Subsidiary  thereof to determine  compliance  with any covenant
contained herein,  shall, except as otherwise  expressly  contemplated hereby or
unless there is an express written direction by the Administrative  Agent to the
contrary agreed to by the Borrowers,  be performed in accordance with GAAP as in
effect on the Closing  Date. In the event that after the Closing Date changes in
GAAP shall be mandated  by the  Financial  Accounting  Standards  Board,  or any
similar accounting body of comparable standing, or changes shall be recommended,
consented  to or  concurred  in by  the  certified  public  accountants  of  the
Borrowers, to the extent that such changes would modify such accounting terms or
the  interpretation  or computation  thereof,  such changes shall be followed in
defining  such  accounting  terms only from and after the date the Borrowers and
the Lenders shall have amended this Agreement to the extent necessary to reflect
any such changes in the financial  covenants  and other terms and  conditions of
this Agreement.

     SECTION 14.10 Successors and Assigns; Participations.

     (a) Benefit of Agreement. This Agreement shall be binding upon and inure to
the benefit of the Borrowers,  the Agents and the Lenders, all future holders of
the  Notes,  and  their  respective  successors  and  assigns,  except  that the
Borrowers shall not assign or transfer any of their rights or obligations  under
this Agreement without the prior written consent of each Lender.

     (b)  Assignment  by  Lenders.  Each  Lender  may,  with the  consent of the
Borrowers  (so long as no  Default  or  Event of  Default  has  occurred  and is

not be unreasonably withheld,  assign to one or more Eligible Assignees all or a
portion  of  its  interests,   rights  and  obligations   under  this  Agreement
(including,  without limitation, all or a portion of the Extensions of Credit at

hereunder,  to pay to the Administrative Agent and the Lenders an amount greater

Borrower,  such Borrower shall have an enforceable right of contribution against
the  remaining  Borrowers,  and the  remaining  Borrowers  shall be jointly  and
severally  liable,  for  repayment  of the full amount of such  excess  payment.
Subject only to the subordination provided in the following subsection (f), such
Borrower further shall be subrogated to any and all rights of the Administrative

Section 14.19,  be rendered  insolvent under any Applicable Law by reason of its
incurring of obligations  to any other Borrower under the foregoing  subsections

indemnity,  to the full extent provided in the foregoing subsections (c) and (d)
above, against the remaining Borrowers,  such that all Obligations of all of the

<PAGE>

     (f) The rights of any Borrower to  contribution,  subrogation and indemnity
under this  Section  14.19 or under  Applicable  Law shall in all events and all
respects be subject and  subordinate to the rights of the  Administrative  Agent
and the Lenders under this  Agreement  and subject to the prior full,  final and
indefeasible  payment  to  the  Administrative  Agent  and  the  Lenders  of all
Obligations  and no such right may be  exercised  until all of such  Obligations

provision of the Security  Documents  which  imposes  additional  burdens on any
Borrower  or any  Subsidiary  thereof  or  further  restricts  the rights of any
Borrower  or any  Subsidiary  thereof or gives the Agents or Lenders  additional
rights shall not be deemed to be in conflict or inconsistent with this Agreement
and shall be given full force and effect.

                         REPRESENTATIONS AND WARRANTIES

     The Assignors represent and warrant that:

     SECTION 2.01 Title to  Collateral.  Each  Assignor has good and  marketable
title to all of the  Collateral,  free and clear of any Liens  other  than Liens
permitted by Section 11.3 of the Credit  Agreement.  Each Assignor has taken all
actions  necessary  under the UCC to perfect its  interest in any  Accounts  and
"chattel  paper" (as defined in the UCC) purchased or otherwise  acquired by it,
as against its  assignors  and  creditors  of its  assignors.  No  Assignor  has
performed any acts which might prevent the  Collateral  Agent from enforcing any
of the terms of this Agreement or which would limit the Collateral  Agent in any
such enforcement. Other than financing statements or other similar or equivalent
documents  or  instruments  with  respect to the  Security  Interests  and Liens
permitted  by Section  11.3 of the Credit  Agreement,  no  financing  statement,
mortgage,  security  agreement or similar or  equivalent  document or instrument
covering  all or any  part of the  Collateral  is on file  or of  record  in any
jurisdiction  in which such filing or recording  would be effective to perfect a
Lien on such Collateral. No Collateral is in the possession of any Person (other
than the Assignor) asserting any claim thereto or security interest therein, (a)
except as provided in Schedule 11.3 of the Credit  Agreement and (b) except that
the  Collateral  Agent or its  designee may have  possession  of  Collateral  as
contemplated hereby and by the Credit Agreement.

     SECTION 2.02 Validity,  Perfection and Priority of Security Interests.  The
Security  Interests  constitute valid security  interests under the UCC securing
the  Obligations.   When  UCC  financing   statements  or  financing   statement
amendments,  as  applicable,  containing a description  of the Collateral in the
form  specified  in  Exhibit  B hereto  shall  have  been  filed in the  offices
specified in Schedule  4.01  hereto,  the Security  Interests  shall  constitute
perfected  security  interests in all right, title and interest of the Assignors
in the  Collateral  to  the  extent  that a  security  interest  therein  may be
perfected by filing  pursuant to the UCC, prior to all other Liens and rights of
others  therein  except  for  Liens  permitted  by  Section  11.3 of the  Credit
Agreement.

     SECTION 2.03  Insurance.  The Equipment is insured in  accordance  with the
requirements of the Credit Agreement and Section 4.10 of this Agreement.

                                   ARTICLE III
                                SECURITY INTEREST

     SECTION 3.01 Grant of Security  Interests.  In order to secure the full and
punctual payment of the Obligations in accordance with the terms thereof, and to
secure the performance of all of the obligations of the Assignors  hereunder and
the  Borrowers  under the Credit  Agreement and the other Loan  Documents,  each
Assignor hereby grants to the Collateral Agent a continuing security interest in
and to all of the  Collateral,  whether  now  owned  or  existing  or  hereafter
acquired,  created or arising, whether tangible or intangible, and regardless of
where located.

     SECTION  3.02  Continuing   Liability  of  the  Borrowers;   Right  to  Use
Collateral.  The Security  Interests  are granted as security only and shall not
subject the Collateral Agent or the Lenders to, or transfer or in any way affect
or modify,  any  obligation  or liability of any Assignor with respect to any of
the Collateral or any transaction in connection therewith. So long as no Default
or Event of Default shall have occurred and be  continuing,  each Assignor shall
have the right to use its  Collateral  except to the extent  otherwise  provided
herein with respect to the Collateral Accounts.

     SECTION 3.03 Cash Proceeds Account.

     (a) Creation of Cash Proceeds Account. There is hereby established with the
Collateral Agent a cash collateral  account (the "Cash Proceeds Account") in the
name of "GTS DURATEK,  INC. - FIRST UNION NATIONAL BANK" and under the exclusive
control of the Collateral Agent into which there shall be deposited from time to
time the  cash  proceeds  of the  Collateral  required  to be  delivered  to the
Collateral  Agent  pursuant  to  paragraph  (b) of  this  Section  or any  other
provision of the Loan  Documents.  Any income  received by the Collateral  Agent
with respect to the balance from time to time standing to the credit of the Cash
Proceeds Account,  including any interest, shall remain, or be deposited, in the
Cash Proceeds Account.  All right, title and interest in and to the cash amounts
on deposit from time to time in the Cash Proceeds  Account shall constitute part
of the  Collateral  and shall not constitute  payment of the  Obligations  until
applied thereto as hereinafter provided.

     (b) Deposits to Cash Proceeds  Account.  Upon the request of the Collateral
Agent upon the occurrence and during the continuation of any Default or Event of
Default,  the  Assignors  shall  instruct all Account  Debtors and other Persons
obligated  in respect of Accounts and other  Collateral  to make all payments in
respect of the Accounts or other Collateral  directly to a post office box which
shall be in the name and under the  control of the  Collateral  Agent.  All such
payments  made to the  Collateral  Agent shall be deposited in the Cash Proceeds
Account. In addition to the foregoing,  upon the request of the Collateral Agent
upon the  occurrence  and  during  the  continuation  of a  Default  or Event of
Default,  each Assignor agrees that if the proceeds of any Collateral (including
the payments made in respect of Accounts) shall be received by it, such Assignor


                                       8

<PAGE>


shall as promptly as possible deposit such proceeds to the Cash Proceeds Account
and  until  so  deposited,  all  such  proceeds  shall  be held in trust by such
Assignor  for and as the  property  of the  Collateral  Agent  and  shall not be
commingled  with any other  funds or property of such  Assignor.  The  Assignors
hereby  irrevocably  authorize and empower the Collateral  Agent,  its officers,
employees and  authorized  agents to endorse and sign their names on all checks,
drafts,  money  orders  or  other  media  of  payment  so  delivered,  and  such
endorsements or assignments shall, for all purposes, be deemed to have been made
by  the  Assignors  prior  to  any  endorsement  or  assignment  thereof  by the
Collateral Agent. The Collateral Agent may use any convenient or customary means
for the purpose of collecting such checks,  drafts,  money orders or other media
of payment.

     (c) Withdrawals from Cash Proceeds Account.  Upon the occurrence and during
the continuation of a Default or Event of Default, collected funds on deposit in
the Cash  Proceeds  Account  shall be withdrawn by the  Collateral  Agent on the
Business Day following the day on which the Collateral Agent considers the funds
deposited  therein to be  collected  funds and applied to repay the  Obligations
which  are  then due and  payable  pursuant  to  Section  5.04 of this  Security
Agreement and, if applicable, Section 5.5 of the Credit Agreement.

     SECTION 3.04 Cash Collateral Account.  All amounts required to be deposited
by the Assignors as cash collateral  pursuant to Section 5.04(b) hereof shall be
deposited  in  a  cash  collateral  account  (the  "Cash  Collateral   Account")
established  and  maintained by each  Assignor at the offices of the  Collateral
Agent or such other bank as such Assignor and the Collateral Agent may agree, in
the name and under the exclusive control of the Collateral Agent. Forthwith upon
such  establishment,  such  Assignor  shall notify the  Collateral  Agent of the
location,  account name and account number of such account.  Any income received
with respect to the balance from time to time standing to the credit of the Cash
Collateral   Account,   including  any  interest  or  capital  gains  on  Liquid
Investments,  shall remain, or be deposited, in the Cash Collateral Account. All
right,  title and  interest in and to the cash  amounts on deposit  from time to
time in the Cash Collateral  Account  together with any Liquid  Investments from
time  to time  made  pursuant  to  Section  3.05  shall  constitute  part of the
Collateral  hereunder and shall not constitute  payment of the Obligations until
applied  thereto as  hereinafter  provided.  If and when any  portion of the L/C
Obligations on which any deposit in the Cash  Collateral  Account was based (the
"Relevant  Contingent  Exposure") shall become fixed (a "Direct  Exposure") as a
result of the  payment by the  issuer  thereof  of a draft  presented  under any
Letter of Credit,  the  amount of such  Direct  Exposure  (but not more than the
amount in the Cash  Collateral  Account at the time) shall be  withdrawn  by the
Collateral  Agent from the Cash Collateral  Account for application  pursuant to
Section 5.04 and, if applicable,  Section 5.5 of the Credit  Agreement,  and the
Relevant  Contingent  Exposure  shall  thereupon be reduced by such  amount.  If
immediately  available  cash on  deposit in the Cash  Collateral  Account is not
sufficient to make any  distribution to the Collateral Agent referred to in this
Section 3.04, the  Collateral  Agent shall cause to be liquidated as promptly as
practicable such Liquid Investments in the Cash Collateral Account designated by
Duratek as required to obtain  sufficient  cash to make such  distribution  and,
notwithstanding  any other  provision of this Section  3.04,  such  distribution
shall not be made until such  liquidation has taken place. So long as no Default
or Event of Default shall have occurred and be continuing, the funds in the Cash
Collateral Account in excess of the Relevant  Contingent  Exposure shall be paid
to Duratek on demand.

     SECTION 3.05 Investment of Funds in Collateral Accounts. Amounts on deposit
in the Cash  Collateral  Account shall be invested and  reinvested  from time to
time in such  Liquid  Investments  as  Duratek  shall  determine,  which  Liquid
Investments shall be held in the name and be under the control of the Collateral
Agent,  provided  that,  if a Default or an Event of Default has occurred and is
continuing,  the Collateral Agent may liquidate any such Liquid  Investments and
apply or cause to be applied the  proceeds  thereof in the manner  specified  in
Section 5.04. For this purpose,  "Liquid  Investments"  means Cash  Equivalents;
provided that (a) each Liquid  Investment  shall mature within 180 days after it
is acquired by the  Collateral  Agent and (b) in order to provide the Collateral
Agent with a perfected  security interest therein,  each Liquid Investment shall
be either:

                    (i) evidenced by negotiable certificates or instruments,  or
               if nonnegotiable then issued in the name of the Collateral Agent,
               which (together with any appropriate instruments of transfer) are
               delivered  to,  and held  by,  the  Collateral  Agent or an agent
               thereof   (which  shall  not  be  any  Assignor  or  any  of  its
               Affiliates) in the State of North Carolina; or

                    (ii) in book-entry  form and issued by the United States and
               subject  to  pledge  under  applicable  state  law  and  Treasury
               regulations  and as to which (in the  opinion  of  counsel to the
               Collateral Agent) appropriate  measures shall have been taken for
               perfection of the Security Interests.


                                   ARTICLE IV
                                    COVENANTS

     The Assignors  covenant and agree with the Collateral  Agent that until the
payment in full of all  Obligations  and  termination  of the  Commitments,  the
Assignors will comply with the following:

     SECTION  4.01  Delivery  of  Perfection  Certificate;  Filing of  Financing
Statements  and  Delivery of Search  Reports.  On or prior to the Closing  Date,
each Assignor shall deliver a Perfection Certificate to the Collateral Agent and
shall cause all  filings,  recordings,  notices and other  actions  specified in
Schedule 4.01 hereto to have been  completed.  The  information set forth in the
Perfection  Certificate  shall be correct  and  complete.  At the expense of the
Assignors,  the Collateral  Agent shall be entitled to file search  requests and
confirmations  of receipt  of notices  from each  filing  jurisdiction  and each
notice  recipient set forth in Schedule 4.01  confirming the filing  information
set forth in such Schedule.

     SECTION 4.02 Change of Name, Identity or Structure;  Locations of Places of
Business,  Chief  Executive  Office and Collateral.  No Assignor will change its
name,  identity or corporate  structure in any manner unless it shall have given
the  Collateral  Agent not less than ten (10) days'  prior  notice  thereof.  No
Assignor  will change the location of (a) its place or places of  business,  its
chief executive office or its chief place of business or (b) the locations where
it keeps or holds  any  Collateral  or any  records  relating  thereto  from the
applicable location described in such Assignor's  Perfection  Certificate unless


                                       10


<PAGE>

it shall have given the  Collateral  Agent not less than thirty (30) days' prior
notice  thereof,  provided,  however,  that Equipment may be moved without prior
notice  to the  Collateral  Agent  within  or into  any  jurisdiction  in  which
financing  statements  have been filed which  perfect the security  interests in
such Equipment in such  jurisdiction.  In any event, no Assignor will change the
location of its place or places of business,  its chief executive  office or any
Collateral if such change would cause the Security  Interests in such Collateral
to lapse or cease to be perfected.

     SECTION 4.03 Further Assurances.  Each Assignor will, from time to time, at
its  expense,  execute,  deliver,  file and  record any  statement,  assignment,
instrument,  document,  agreement  or other  paper  and take  any  other  action
(including,  without  limitation,  any  filings  of  financing  or  continuation
statements  under  the UCC,  any  filings  with the  United  States  Patent  and
Trademark  Office and any Notices of Assignment  under the  Assignment of Claims
Act),  that  from  time to time  may be  necessary  or  desirable,  or that  the
Collateral Agent may request, in order to create, preserve,  perfect, confirm or
validate the Security  Interests or to enable the Collateral Agent to obtain the
full benefit of this  Agreement,  or to enable the Collateral  Agent to exercise
and enforce any of its rights,  powers and remedies  created  hereunder or under
Applicable Law with respect to any of the Collateral. To the extent permitted by
Applicable Law, each Assignor hereby  authorizes the Collateral Agent to execute
and file financing statements or continuation statements without such Assignor's
signature appearing thereon.  Each Assignor agrees that a carbon,  photographic,
photostatic or other reproduction of this Agreement or of a financing  statement
is sufficient as a financing statement. The Assignors shall pay the costs of, or
incidental  to,  any  recording  or  filing  of any  financing  or  continuation
statements concerning the Collateral.

     SECTION 4.04  Collateral in Possession of Other Persons.  If any Collateral
is at any time in the possession or control of any  warehouseman,  bailee or any
Assignor's agents or processors,  such Assignor shall notify such  warehouseman,
bailee,  agent or processor of the Security Interests created hereby and to hold
all such Collateral for the Collateral Agent's account subject to the Collateral
Agent's instructions.

     SECTION 4.05 Books and Records.  The Assignors shall keep full and accurate
books and records relating to the Collateral, including, without limitation, the
originals of all  documentation  with respect  thereto,  records of all payments
received,  all credits granted thereon,  all merchandise  returned and all other
dealings  therewith,  and the  Assignors  will  make the same  available  to the
Collateral Agent for inspection,  at the Assignors' own cost and expense, at any
and all reasonable  times upon demand.  Upon direction by the Collateral  Agent,
the  Assignors  shall  stamp or  otherwise  mark such books and  records in such
manner as the Collateral  Agent may  reasonably  require in order to reflect the
Security Interests.


                                       11

<PAGE>

     SECTION 4.06  Delivery of  Instruments.   The  Assignors  will  immediately
deliver each Instrument,  certificated  security and uncertificated  security to
the Collateral Agent indorsed (as applicable) to the Collateral Agent;  provided
that so long as no  Default  or Event of  Default  shall  have  occurred  and be
continuing and except as provided by any other Loan Document,  the Assignors may
retain for collection in the ordinary course of business any Instruments  (other
than certificated securities,  checks, drafts and other Instruments constituting
payments in respect of Accounts and other Collateral, as to which the provisions
of Section 3.03 hereof shall apply)  received by them in the ordinary  course of
business and the Collateral Agent shall,  promptly upon request of any Assignor,
make appropriate  arrangements  for making any other Instrument  pledged by such
Assignor  available to it for purposes of  presentation,  collection  or renewal
(any such  arrangement to be effected,  to the extent deemed  appropriate to the
Collateral Agent, against trust receipt or like document).

     SECTION 4.07 Modification of Assigned Agreements, Etc.  Each Assignor shall
keep the Collateral  Agent informed of all material  circumstances  bearing upon
the right, title and interest of such Assignor under the Assigned Agreements. No
Assignor will,  except with the consent of the Collateral  Agent amend,  modify,
extend,  renew,  cancel or terminate any Assigned  Agreement,  waive any default
under or breach of any  Assigned  Agreement,  compromise  or settle any material
dispute,  claim,  suit or legal proceeding  relating to any Assigned  Agreement,
sell or assign any Assigned Agreement or interest therein,  consent to or permit
or accept any  prepayment of amounts to become due under or in  connection  with
any Assigned Agreement,  except as expressly provided therein, or take any other
action in connection with any Assigned Agreement which would impair the value of
the  interests or rights of such  Assignor  thereunder or which would impair the
interests or rights of the Collateral  Agent under this Agreement,  except that,
unless  the  Collateral  Agent  shall  have  notified  such  Assignor  upon  the
occurrence  of a Default or Event of Default  that this  exception  is no longer
applicable,  such Assignor may modify,  make adjustments with respect to, extend
or renew  any  Assigned  Agreements  in the  ordinary  course of  business.  The
Assignor will duly fulfill all of its  obligations  under or in connection  with
the  Assigned  Agreements  unless the failure to do so could not  reasonably  be
expected to have a Material Adverse Effect.

     SECTION 4.08 Equipment;  Fixtures.  The Assignors shall promptly inform the
Collateral  Agent of any material  additions to or deletions  from the Equipment
and shall not permit  any such  items to become a fixture  to real  estate or an
accession to other personal property.

     SECTION 4.09  Disposition of Collateral.  Without the prior written consent
of the Collateral Agent, the Assignors will not sell, lease, exchange, assign or
otherwise  dispose  of, or grant any option  with  respect  to, any  Collateral,
except  that,  subject  to the rights of the  Collateral  Agent  hereunder  if a
Default  or an Event of Default  shall  have  occurred  and be  continuing,  the
Assignors may grant Licenses in their  respective  Patents and Trademarks in the
ordinary course of their businesses, and to the extent permitted by Section 11.6
of the Credit  Agreement,  the Assignors may sell,  lease or exchange  obsolete,
unused or unnecessary  Equipment in the ordinary course of business,  whereupon,
in the case of such a sale or exchange, the Security Interests created hereby in
such item (but not in any Proceeds  arising  from such sale or  exchange)  shall
cease  immediately  without  any  further  action on the part of the  Collateral
Agent.


                                       12

     SECTION 4.10  Insurance.  Prior to the Closing  Date,  each  Assignor  will
cause the  Collateral  Agent to be named as an  insured  party and loss payee on
each insurance  policy  covering  risks  relating to any of its Equipment.  Each
Assignor will deliver to the Collateral Agent,  upon its request,  the insurance
policies  for such  insurance  or  certificates  of  insurance  evidencing  such
coverage.  Each such  insurance  policy shall include  effective  waivers by the
insurer of all claims for  insurance  premiums  against  the  Collateral  Agent,
provide for coverage to the  Collateral  Agent  regardless of the breach by such
Assignor  of any  warranty or  representation  made  therein,  not be subject to
co-insurance,  provide  that all  insurance  proceeds in excess of $250,000  per
claim shall be payable to such  Assignor  and the  Collateral  Agent and provide
that no  cancellation,  termination  or material  modification  thereof shall be
effective until at least thirty (30) days after receipt by the Collateral  Agent
of notice thereof. So long as no Default or Event of Default has occurred and is
continuing, the Collateral Agent shall deliver the proceeds of any claims in the
Collateral Agent's possession to the Assignor. Each Assignor hereby appoints the
Collateral  Agent as its  attorney-in-fact  to make  proof of  loss,  claim  for
insurance  and  adjustments  with  insurers,  and  to  execute  or  endorse  all
documents,  checks or drafts in connection with payments made as a result of any
insurance  policies,  but the Collateral Agent agrees not to exercise any of the
foregoing rights unless a Default or an Event of Default shall have occurred and
be  continuing.  Each  Assignor  assumes all  liability  and  responsibility  in
connection with the Collateral acquired by it and the liability of such Assignor
to pay the  Obligations  shall in no way be affected or  diminished by reason of
the fact that such Collateral may be lost, destroyed, stolen, damaged or for any
reason whatsoever unavailable to such Assignor.

     SECTION  4.11  Information  Regarding  Collateral.    The  Assignors  will,
promptly upon  request,  provide to the  Collateral  Agent all  information  and
evidence it may  reasonably  request  concerning  the  Collateral  to enable the
Collateral Agent to enforce the provisions of this Agreement.

     SECTION 4.12 Covenants Regarding Patent and Trademark Collateral.

     (a) Each  Assignor  (either  itself or through  licensees)  will,  for each
Patent,  not do any act,  or omit to do any act,  whereby  any  Patent  which is
material to the conduct of such  Assignor's  business may become  invalidated or
dedicated to the public,  and shall  continue to mark any products  covered by a
Patent with the relevant patent number or indication that a Patent is pending as
required by the Patent laws.

     (b) Each  Assignor  (either  itself or, if  permitted  by law,  through its
licensees or its sublicensees)  will, for each Trademark material to the conduct
of such Assignor's business, (i) maintain such Trademark in full force free from
any claim of abandonment or invalidity for non-use, (ii) maintain the quality of
products and services offered under such Trademark,  display such Trademark with
notice of federal  registration  to the extent  required by Applicable Law, (iv)
not knowingly use or knowingly  permit the use of such Trademark in violation of
any third  party  rights  and (v) not  permit  any  assignment  in gross of such
Trademark.

     (c) Each Assignor (either itself or through  licensees) will, for each work
covered by a material copyright,  continue to publish, reproduce, display, adopt
and distribute the work with appropriate copyright notice.


                                       13

     (d) Each Assignor shall notify the Collateral Agent immediately if it knows
or has  reason  to  know  that  any  Patent,  Trademark  or  copyright  (or  any
application or  registration  relating  thereto)  material to the conduct of its
business may become  abandoned  or  dedicated  to the public,  or of any adverse
determination or development (including, without limitation, the institution of,
or any such determination or development in, any proceeding in the United States
Patent  and  Trademark  Office,  United  States  Copyright  Office or any court)
regarding such Assignor's ownership of any Patent,  Trademark or copyright,  its
right to register the same or to keep and maintain the same.

     (e) Each  Assignor  will take all  necessary  steps to file,  maintain  and
pursue each  material  application  relating to the Patents,  Trademarks  and/or
copyrights  (and to obtain the relevant grant or  registration)  and to maintain
each registration of the Patents, Trademarks and copyrights which is material to
the conduct of such Assignor's  business,  including  filing of applications for
renewal, affidavits of use, affidavits of incontestability and maintenance fees,
and,  if  consistent  with  good  business  judgment,  to  initiate  opposition,
interference and cancellation proceedings against third parties.

     (f) In the event that any rights to any  Patent,  Trademark,  copyright  or
License relating  thereto material to the conduct of any Assignor's  business is
believed  infringed,  misappropriated or diluted by a third party, such Assignor
shall notify the Collateral Agent promptly after it learns thereof and shall, if
consistent  with  good  business   judgment,   promptly  sue  for  infringement,
misappropriation  or  dilution  and to  recover  any and all  damages  for  such
infringement,  misappropriation or dilution, and take such other actions as such
Assignor shall  reasonably deem appropriate  under the  circumstances to protect
such Patent, Trademark, copyright or License.

     (g) In no event  shall any  Assignor,  either  itself or through any agent,
employee, licensee or designee, file an application for any Patent, Trademark or
copyright  with the United  States Patent and  Trademark  Office,  United States
Copyright  Office or any office or agency in any  political  subdivision  of the
United  States or in any other  country or any  political  subdivision  thereof,
unless not less than ten (10) days  prior  thereto  it  informs  the  Collateral
Agent, and, upon request of the Collateral Agent,  executes and delivers any and
all agreements,  instruments,  documents and papers as the Collateral  Agent may
request  to  evidence  the  Security  Interests  in such  Patent,  Trademark  or
copyright and the goodwill or accounts and general  intangibles of such Assignor
relating thereto or represented  thereby,  and such Assignor hereby appoints the
Collateral Agent its  attorney-in-fact to execute and file such writings for the
foregoing purposes.

                          REMEDIES; RIGHTS UPON DEFAULT

     SECTION 5.01 General Authority.  The Assignors hereby  irrevocably  appoint
the  Collateral  Agent  their  true and  lawful  attorney,  with  full  power of
substitution,  in the name of any or all of the Assignors,  the Collateral Agent
or  otherwise,  in the  name  of each  Assignor,  the  Agents,  the  Lenders  or
otherwise,  for the sole use and  benefit of the  Collateral  Agent,  but at the
Assignors'  expense,  to the extent permitted by law to exercise at any time and
from time to time while an Event of Default has occurred and is continuing,  all
or any of the following powers with respect to all or any of the Collateral, all
acts of such attorney  being hereby  ratified and confirmed;  such power,  being
coupled with an interest,  is irrevocable until the Obligations are paid in full
and the Commitments are terminated:

                    (a)  to  demand,   sue  for,   collect,   receive  and  give
               acquittance  for any and all  monies  due or to  become  due with
               respect to any Collateral or by virtue thereof,

                    (b) to settle, compromise, compound, prosecute or defend any
               action or proceeding with respect to any Collateral,

                    (c) to sell,  transfer,  assign or otherwise deal in or with
               the same or the  proceeds or avails  thereof,  including  without
               limitation  for  the  implementation  of any  assignment,  lease,
               License,  sublicense,  grant of option, sale or other disposition
               of any  Patent,  Trademark  or  copyright  or any action  related
               thereto, as fully and effectually as if the Collateral Agent were
               the absolute owner thereof, and

                    (d) to extend the time of payment of any or all  thereof and
               to make any allowance and other adjustments with reference to the
               Collateral;

provided  that the  Collateral  Agent shall give such Assignor not less than ten
(10)  days'  prior  notice of the time and  place of any sale or other  intended
disposition of any of such Assignor's Collateral, except any Collateral which is
perishable or threatens to decline speedily in value or is of a type customarily
sold on a recognized  market.  The Collateral Agent and such Assignor agree that
such notice constitutes "reasonable  notification" within the meaning of Section
9-504(3) of the UCC. Except as otherwise  provided herein,  each Assignor hereby
waives,  to the extent  permitted by Applicable Law, notice and judicial hearing
in connection  with the Collateral  Agent's taking  possession or the Collateral
Agent's  dispositions of any of the Collateral,  including,  without limitation,
any and all prior notice and hearing for any prejudgment  remedy or remedies and
any such right which such Assignor would  otherwise have under the  Constitution
or any statute of the United States or of any state.

     SECTION 5.02 Remedies upon Event of Default.

     (a) If any Event of Default has occurred and is continuing,  the Collateral
Agent may  exercise  on  behalf  of  itself,  the  Administrative  Agent and the
Lenders, upon the request of the Required Lenders, all rights of a secured party


                                       15



<PAGE>

under the UCC  (whether or not in effect in the  jurisdiction  where such rights
are exercised) and, in addition,  the Collateral  Agent may, upon the request of
the Required Lenders, without being required to give any notice to any Assignor,
except as herein provided or as may be required by mandatory  provisions of law,
(i)  withdraw all cash and Liquid  Investments  in the  Collateral  Accounts and
apply such cash and Liquid  Investments  and other cash, if any, then held by it
as  Collateral  as  specified in Section 5.04 and (ii) if there shall be no such
cash or Liquid  Investments  or if such  cash and  Liquid  Investments  shall be
insufficient  to pay all the Obligations in full or cannot be so applied for any
reason,  sell the  Collateral or any part thereof at public or private sale, for
cash,  upon  credit or for future  delivery,  and at such price or prices as the
Collateral Agent may deem satisfactory. The Collateral Agent, the Administrative
Agent or any Lender may be the purchaser of any or all of the Collateral so sold
at any public sale (or, if the  Collateral  is of a type  customarily  sold in a
recognized  market or is of a type which is the  subject  of widely  distributed
standard price  quotations,  at any private sale) and  thereafter  hold the same
absolutely,  free from any right or claim of whatsoever kind. The Assignors will
execute and deliver such  documents and take such other action as the Collateral
Agent deems  necessary  or  advisable in order that any such sale may be made in
compliance  with law. Upon any such sale,  the  Collateral  Agent shall have the
right to deliver, assign and transfer to the purchaser thereof the Collateral so
sold  (without  warranty).  Each  purchaser  at any  such  sale  shall  hold the
Collateral  so sold to it  absolutely  and  free  from  any  claim  or  right of
whatsoever  kind,  including  any equity or right of redemption of the Assignors
which may be waived,  and the Assignors,  to the extent permitted by law, hereby
specifically  waive all rights of redemption,  stay or appraisal which they have
or may have under any law now existing or hereafter adopted. The notice (if any)
of such sale  required by Section  5.01 shall (i) in the case of a public  sale,
state the time and place fixed for such sale,  and (ii) in the case of a private
sale,  state the day after which such sale may be  consummated.  Any such public
sale shall be held at such time or times within  ordinary  business hours and at
such place or places as the Collateral Agent may fix in the notice of such sale.
At any such  sale the  Collateral  may be sold in one lot as an  entirety  or in
separate  parcels,  as the Collateral Agent may determine.  The Collateral Agent
shall not be  obligated to make any such sale  pursuant to any such notice.  The
Collateral  Agent may,  without  notice or  publication,  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  without further  notice.  In the
case of any sale of all or any part of the  Collateral  on credit or for  future
delivery,  the Collateral so sold may be retained by the Collateral  Agent until
the selling price is paid by the purchaser  thereof,  but the  Collateral  Agent
shall not incur any  liability  in the case of the failure of such  purchaser to
take up and pay for the Collateral so sold and, in the case of any such failure,
such  Collateral  may again be sold  upon like  notice.  The  Collateral  Agent,
instead of exercising the power of sale herein conferred upon it, may proceed by
a suit or suits at law or in equity to foreclose the Security Interests and sell
the Collateral, or any portion thereof, under a judgment or decree of a court or
courts of  competent  jurisdiction.  The  Assignors  shall  remain  jointly  and
severally liable for any deficiency.

     (b) For the purpose of enforcing any and all rights and remedies under this
Agreement  the  Collateral  Agent may (i)  require  the  Assignors  to, and each
Assignor  agrees  that it will,  at its  expense  and upon  the  request  of the
Collateral  Agent,  forthwith  assemble  all or any  part of the  Collateral  as
directed by the Collateral  Agent and make it available at a place designated by
the Collateral  Agent which is, in the Collateral  Agent's  opinion,  reasonably
convenient to the Collateral Agent and such Assignor, whether at the premises of
such Assignor or otherwise,  it being understood that such Assignor's obligation
so to deliver  the  Collateral  is of the  essence of this  Agreement  and that,


                                       16

<PAGE>

accordingly,  upon  application  to a court of equity having  jurisdiction,  the
Collateral Agent shall be entitled to a decree requiring specific performance by
such Assignor of such  obligations;  (ii) to the extent  permitted by Applicable
Law, enter,  with or without process of law and without breach of the peace, any
premise where any of the Collateral is or may be located,  and without charge or
liability to the  Collateral  Agent seize and remove such  Collateral  from such
premises; (iii) have access to and use the Assignors' books and records relating
to the Collateral; and (iv) prior to the disposition of the Collateral, store or
transfer  it  without  charge in or by means of any  storage  or  transportation
facility owned or leased by the Assignors,  process, repair or recondition it or
otherwise  prepare  it for  disposition  in any  manner  and to the  extent  the
Collateral Agent deems  appropriate and, in connection with such preparation and
disposition,  use  without  charge any  Patent,  Trademark,  copyright,  License
relating  thereto or technical  process used by the  Assignors.  The  Collateral
Agent may also render any or all of the  Collateral  unusable at any  Assignor's
premises and may dispose of such Collateral on such premises  without  liability
for rent or costs.

     (c) Without  limiting  the  generality  of the  foregoing,  if any Event of
Default has  occurred and is  continuing  (but subject to the terms of any prior
License permitted hereby):

                         (i) the  Collateral  Agent may license,  or sublicense,
                    whether  general,  special or  otherwise,  and whether on an
                    exclusive or non-exclusive basis, any Patents, Trademarks or
                    copyrights  included in the Collateral  throughout the world
                    for  such  term or  terms,  on such  conditions  and in such
                    manner as the Collateral  Agent shall in its sole discretion
                    determine;

                         (ii) the  Collateral  Agent may  (without  assuming any
                    obligations or liability  thereunder),  at any time and from
                    time to time, enforce (and shall have the exclusive right to
                    enforce)  against any licensee or sublicensee all rights and
                    remedies of the  Assignor  in, to and under any License with
                    respect to any Patent or Trademark,  or license with respect
                    to  copyrights  and take or refrain  from  taking any action
                    under  any  provision  thereof,   and  the  Assignor  hereby
                    releases the  Collateral  Agent from, and agrees to hold the
                    Collateral  Agent free and  harmless  from and  against  any
                    claims arising out of, any lawful action so taken or omitted
                    to be taken with respect thereto; and

                         (iii)  upon  request  by  the  Collateral  Agent,  each
                    Assignor  will use its best efforts to obtain all  requisite
                    consents or approvals by the licensor or sublicensor of each
                    License  with  respect to Patents,  license  with respect to
                    copyrights  or License with respect to  Trademarks to effect
                    the  assignment of all of the Assignor's  rights,  title and
                    interest  thereunder to the Collateral Agent or its designee
                    and will execute and deliver to the Collateral Agent a power
                    of  attorney,  in form  and  substance  satisfactory  to the
                    Collateral  Agent,  for  the  implementation  of any  lease,
                    assignment,  license,  sublicense,  grant of option, sale or
                    other disposition of a Patent, Trademark or copyright; and



                                      17


<PAGE>

                         (iv) the  Collateral  Agent may direct any  Assignor to
                    refrain,  in which event such Assignor shall  refrain,  from
                    using or practicing  any  Trademark,  Patent or copyright in
                    any manner whatsoever,  directly or indirectly and shall, if
                    requested by the  Collateral  Agent  change such  Assignor's
                    name to eliminate  therefrom  any use of any  Trademark  and
                    will  execute  such  other  and  further  documents  as  the
                    Collateral  Agent may  request to further  confirm  this and
                    transfer  ownership of the Trademarks,  Patents,  copyrights
                    and registrations and any pending  applications  therefor to
                    the Collateral Agent.

     (d) In the event of any  disposition of any Patent,  Trademark or copyright
pursuant to this  Article V, the  Assignors  shall  supply  their  know-how  and
expertise  relating  to the  manufacture  and sale of the  products  or services
bearing  Trademarks  or the  products,  services  or works made or  rendered  in
connection with or under Patents,  Trademarks or copyrights,  and their customer
lists and other records  relating to such Patents,  Trademarks or copyrights and
to the  distribution  of said  products,  services or works,  to the  Collateral
Agent.

     (e) If any Event of Default has occurred and is  continuing,  each Assignor
shall use its best efforts upon the reasonable  request of the Collateral  Agent
to obtain from the appropriate  governmental  authorities the necessary consents
and  approvals,  if any,  for the  assignment  or transfer  of any  governmental
authorizations, governmental licenses and governmental permits to the Collateral
Agent or its designee upon acceleration of the Obligations.

     SECTION  5.03  Limitation  on Duty of the  Collateral  Agent in  Respect of
Collateral.  Beyond the exercise of reasonable care in the custody thereof,  the
Collateral  Agent shall have no duty to exercise any rights or take any steps to
preserve the rights of any Assignor in the Collateral in its or such  Assignors
possession or control or in the  possession or control of any agent or bailee or
any income thereon or as to the  preservation of rights against prior parties or
any other rights pertaining thereto, nor shall the Collateral Agent be liable to
the Assignor or any other Person for failure to meet any  obligation  imposed by
Section 9-207 of the UCC or any successor provision.  The Collateral Agent shall
be deemed to have exercised  reasonable care in the custody and  preservation of
the  Collateral  in its  possession  if the  Collateral  is  accorded  treatment
substantially equal to that which it accords its own property,  and shall not be
liable or responsible  for any loss or damage to any of the  Collateral,  or for
any  diminution  in the value  thereof,  by reason of the act or omission of any
warehouseman,  carrier,  forwarding  agency,  consignee or other agent or bailee
selected by the Collateral Agent in good faith.

     SECTION 5.04 Application of Proceeds.

     (a) Priority of  Distribution.  If an Event of Default  shall have occurred
and be continuing,  the proceeds of any sale of, or other  realization upon, all
or any part of the Collateral and any cash held in the Collateral Accounts shall
be applied by the Collateral  Agent in accordance with Section 5.5 of the Credit
Agreement,  and then to payment to the Assignors or their  successors or assigns
or as a  court  of  competent  jurisdiction  may  direct,  or any  surplus  then
remaining  from  such  proceeds.  The  Collateral  Agent  may make  distribution
hereunder in cash or in kind or, on a ratable basis in any combination thereof.



                                       18

<PAGE>


     (b) Distributions  with Respect to Letters of Credit.  The Collateral Agent
agrees and acknowledges  that if (after all outstanding  Loans and Reimbursement
Obligations  with  respect  to  Letters  of  Credit  have been paid in full) the
Collateral Agent is to receive a distribution on account of undrawn amounts with
respect  to  Letters  of Credit  issued  (or  deemed  issued)  under the  Credit
Agreement,  such amounts  shall be deposited in the Cash  Collateral  Account as
cash  security  for  the  repayment  of  Obligations.  Upon  termination  of all
outstanding Letters of Credit, all of such cash security shall be applied to the
remaining  Obligations.  If there  remains  any  excess  cash  security  in such
accounts,  such  excess  cash shall be  withdrawn  by the  Collateral  Agent and
distributed in accordance with Section 5.04(a) hereof.

     (c) It is understood  that the Assignors shall remain jointly and severally
liable to the extent of any deficiency between the amount of the proceeds of the
Collateral and the amount of the Obligations.

     SECTION  5.05  Assigned  Agreements.    Each  Assignor  hereby  irrevocably
authorizes and empowers the  Collateral  Agent,  in the Collateral  Agent's sole
discretion,  if an Event of Default has occurred and is  continuing,  to assert,
either  directly or on behalf of such  Assignor,  any claims such  Assignor  may
have, from time to time, against any other party to any Assigned Agreement or to
otherwise  exercise  any  right or remedy of such  Assignor  under any  Assigned
Agreement  (including without limitation,  the right to enforce directly against
any party to an Assigned Agreement all of such Assignor's rights thereunder,  to
make all  demands  and give all  notices  and  make  all  requests  required  or
permitted  to be made by such  Assignor  under any Assigned  Agreements)  as the
Collateral  Agent may deem  proper.  Each  Assignor  hereby  irrevocably  makes,
constitutes  and appoints the Collateral  Agent (and all officers,  employees or
agents  designated by the Collateral  Agent) as such  Assignor's true and lawful
attorney-in-fact for the purpose of enabling the Collateral Agent, to assert and
collect such claims and to exercise such rights and remedies.

     SECTION 5.06  Concerning  the Collateral  Agent.  The provisions of Article
XIII of the Credit  Agreement shall inure to the benefit of the Collateral Agent
in respect to this Agreement and shall be binding upon the parties to the Credit
Agreement in such respect.  In furtherance  and not in derogation of the rights,
privileges and immunities of the Collateral Agent therein set forth:

     (a) The  Collateral  Agent is  authorized  to take all  such  action  as is
provided to be taken by it as  Collateral  Agent  hereunder and all other action
incidental  thereto.  As to any matters not expressly  provided for herein,  the
Collateral  Agent may  request  instructions  from the  Lenders and shall act or
refrain from acting in accordance  with written  instructions  from the Required
Lenders (or, when expressly  required by this Agreement or the Credit Agreement,
all the Lenders) or, in the absence of such instructions, in accordance with its
discretion.

     (b) The  Collateral  Agent  shall  not be  responsible  for the  existence,
genuineness or value of any of the  Collateral or for the validity,  perfection,
priority  or  enforceability  of the  Security  Interests,  whether  impaired by
operation  of law or by reason  of any  action  or  omission  to act on its part
(other than any such action or inaction constituting gross negligence or willful
misconduct).  The Collateral Agent shall have no duty to ascertain or inquire as
to the  performance  or observance of any of the terms of this  Agreement by any
Assignor.

                                  MISCELLANEOUS

     SECTION  6.01 Notices.  Unless  otherwise  specified  herein,  all notices,
requests  or other  communications  to any party  hereunder  shall be in writing
(including bank wire,  telex,  facsimile  transmission  or similar  writing) and
shall be given or made to such  party in  accordance  with  Section  14.1 of the
Credit Agreement.

     SECTION  6.02 No Waivers;  Non-Exclusive  Remedies.  No failure or delay on
the part of the  Collateral  Agent,  the  Administrative  Agent or any Lender to
exercise,  no course of dealing with respect to, and no delay in exercising  any
right, power or privilege under this Agreement or any other Loan Document or any
other  document or agreement  contemplated  hereby or thereby 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. The rights and remedies provided herein and
in the other Loan  Documents are  cumulative  and are not exclusive of any other
remedies  provided  by law.  Without  limiting  the  foregoing,  nothing in this
Agreement  shall impair the right of the Collateral  Agent,  the  Administrative
Agent or any Lender to exercise any right of set-off or counterclaim it may have
and to apply the amount subject to such exercise to the payment of  indebtedness
of each  Assignor  other  than such  Assignor's  indebtedness  under the  Credit
Agreement  and the other  Loan  Documents.  This  Agreement  is a Loan  Document
executed pursuant to the Credit Agreement.

     SECTION  6.03   Compensation   and  Expenses  of  the   Collateral   Agent;
Indemnification.

     (a) Expenses. The Assignors shall pay (i) all out-of-pocket expenses of the
Collateral Agent,  including fees and disbursements of special and local counsel
for the Collateral Agent, in connection with the preparation and  administration
of this Agreement or any document or agreement  contemplated hereby, any consent
or waiver  hereunder or any amendment  hereof or any Default or alleged  Default
and (ii) if Default or an Event of Default occurs,  all  out-of-pocket  expenses
incurred  by  the  Collateral   Agent  and  each  Lender,   including   (without
duplication)  the fees and  disbursements  of outside counsel in connection with
such  Default or Event of Default and  collection,  bankruptcy,  insolvency  and
other enforcement proceedings resulting therefrom.

     (b)  Protection  of  Collateral.  If any Assignor  fails to comply with the
provisions of the Credit  Agreement,  this Agreement or any other Loan Document,
such that the value of any Collateral or the validity, perfection, rank or value
of any Security Interest is thereby diminished or potentially  diminished or put
at risk, the Collateral  Agent, if requested by the Required  Lenders,  may, but
shall not be required to, effect such compliance on behalf of such Assignor, and
such  Assignor  shall  reimburse the  Collateral  Agent for the costs thereof on
demand.  All  insurance  expenses   and all  expenses  of  protecting,  storing,
warehousing,  appraising,  insuring,  handling,  maintaining  and  shipping  the
Collateral,  any and all excise,  property,  sales and use taxes  imposed by any
state,  federal or local  authority on any of the  Collateral,  or in respect of
periodic appraisals and inspections of the Collateral to the extent the same may
be requested  by the  Collateral  Agent from time to time,  or in respect of the
sale or other disposition  thereof shall be borne and paid by the Assignors.  If
any Assignor fails to promptly pay any portion  thereof when due, the Collateral
Agent, the Administrative  Agent or any Lender may, at its option, but shall not

Agent, the  Administrative  Agent or any Lender for any of the foregoing and any
and all other sums for which the Assignors  may become liable  hereunder and all
costs and expenses  (including  attorneys' fees, legal expenses and court costs)
reasonably  incurred by the Collateral  Agent, the  Administrative  Agent or any
such Lender in enforcing  or  protecting  the  Security  Interests or any of its
rights or remedies under this Agreement,  shall,  together with interest thereon
for each day from the date when paid or incurred by the  Collateral  Agent until
paid by the  Assignors at the rate then  applicable to Base Rate Loans under the
Credit Agreement and shall be additional Obligations.

     (c)  Indemnification.  The  Assignors  agree,  jointly  and  severally,  to
indemnify  the  Lenders,  the  Agents,  their  affiliates  and their  respective
directors,  officers,  trustees, agents and employees (each an "Indemnitee") and
hold  each  Indemnitee  harmless  from  and  against  any and  all  liabilities,
obligations,  losses,  damages,  penalties,  claims,  demands,  actions,  suits,
judgments,  costs and expenses of any kind, including,  without limitation,  the
reasonable fees and disbursements of counsel,  which may be incurred by, imposed
on or asserted  against such Indemnitee in connection with any  investigation or
administrative or judicial  proceeding  (whether or not such Indemnitee shall be
designated a party thereto) brought or threatened  relating to or arising out of
this Agreement or in any other way connected with the  enforcement of any of the
terms of, or the preservation of any rights hereunder, or in any way relating to
or arising out of the manufacture,  ownership, ordering,  purchasing,  delivery,
control, acceptance, lease, financing,  possession,  operation, condition, sale,
return  or  other  disposition  or  use of the  Collateral  (including,  without
limitation, latent or other defects, whether or not discoverable), the violation
of the laws of any country,  state or other  governmental body or unit, any tort
(including,  without  limitation,  any  claims,  arising  or  imposed  under the
doctrine of strict liability,  or for or on account of injury to or the death of
any Person (including any Indemnitee),  or property damage),  or contract claim;
provided that no Indemnitee shall have the right to be indemnified hereunder for
such Indemnitee's own gross negligence or willful  misconduct as determined by a
court of competent jurisdiction. The Assignors agree that upon written notice by
any Indemnitee of the assertion of such a liability,  obligation,  loss, damage,
penalty,  claim,  demand,  action,  judgment or suit, the Assignors shall assume
full  responsibility for the defense thereof.  Each Indemnitee agrees to use its
best  efforts  to notify  the  Assignors  of any such  assertion  of which  such
Indemnitee has knowledge.

     (d) Obligations:  Survival.  Any amounts paid by any Indemnitee as to which
such Indemnitee has the right to reimbursement shall constitute Obligations. The
indemnity  obligations  of the  Assignors  contained  in this Section 6.03 shall
continue in full force and effect  notwithstanding the full payment of all Notes
and all of the other Obligations and notwithstanding the discharge thereof.

     SECTION 6.04  Amendments  and Waivers.  Any provision of this Agreement may
be  amended,  changed,  discharged,  terminated  or waived if, but only if, such
amendment  or  waiver is in  writing  and is  signed  by the  Assignors  and the
Collateral Agent in a manner consistent with Section 14.11 of Credit Agreement).

     SECTION 6.05  Successors and Assigns.  This Agreement shall be binding upon
and inure to the benefit of the  Assignors  and the Agents and their  respective
successors and assigns (as permitted by the Credit Agreement),  and in the event
or an assignment of all or any portion of the Obligations, the rights hereunder,
to the extent  applicable to the  indebtedness  so assigned,  may be transferred
with such  indebtedness.  This  Agreement  shall be binding on the Assignors and
their successors and assigns; provided, that the Assignors may not assign any of
their rights or obligations  hereunder  without the prior written consent of the
Agents and the Lenders.

     SECTION 6.06 Limitation of Law; Severability.

     (a) 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 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.

     (b) Any provision of this Agreement which is prohibited or unenforceable in
any  jurisdiction  shall, as to such  jurisdiction,  be ineffective  only to the
extent  of  such  prohibition  or  unenforceability   without  invalidating  the
remainder of such  provision or the  remaining  provisions  hereof or thereof or
affecting  the  validity  or  enforceability  of  such  provision  in any  other
jurisdiction.

     SECTION 6.07 Governing Law.  This Agreement shall be governed by, construed
and enforced in accordance with the laws of the State of North Carolina, without
reference to the conflicts or choice of law principles thereof.

     SECTION 6.08 Consent to  Jurisdiction.  Each  Assignor  hereby  irrevocably
consents to the personal jurisdiction of the state and federal courts located in
Mecklenburg  County,  North Carolina,  in any action,  claim or other proceeding
arising out of or any dispute in connection with this  Agreement,  any rights or
obligations hereunder,  or the performance of such rights and obligations.  Each
Assignor hereby  irrevocably  consents to the service of a summons and complaint
and other process in any action, claim or proceeding brought by any Agent or any
Lender in connection with this Agreement,  any rights or obligations  hereunder,
or the  performance of such rights and  obligations,  on behalf of itself or its
property,  in the  manner  provided  in Section  14.1 of the  Credit  Agreement.
Nothing in this Section 6.08 shall affect the right of the Administrative  Agent
or Lender to serve legal process in any other manner permitted by Applicable Law
or affect the right of any Agent or any Lender to bring any action or proceeding
against any Assignor or its properties in the courts of any other jurisdictions.

     SECTION 6.09. Binding Arbitration; Waiver of Jury Trial.

     (a) Binding  Arbitration.  Upon demand of any party  hereto,  whether  made
before or after institution of any judicial proceeding, any claim or controversy
arising  out of, or  relating to this  Agreement  or any other Loan  Document (a
"Dispute")  between  or among the  parties to this  Agreement  or any other Loan
Document shall be resolved by binding  arbitration  conducted under and governed
by the Commercial Financial Disputes Arbitration Rules (the "Arbitration Rules")
of the American Arbitration  Association (the "AAA") and the Federal Arbitration


                                       22


<PAGE>

Act.  Disputes  may include,  without  limitation,  tort claims,  counterclaims,
disputes  as to whether a matter is subject to  arbitration,  claims  brought as
class  actions,  or claims  arising  from  documents  executed in the future.  A
judgment upon the award may be entered in any court having jurisdiction.

     (b)  Special  Rules.  All  arbitration   hearings  shall  be  conducted  in
Charlotte,  North  Carolina.  A hearing shall begin within 90 days of demand for
arbitration  and all hearings  shall be concluded  within 120 days of demand for
arbitration.  These time  limitations  may not be extended  unless a party shows
cause for extension and then for no more than a total of 60 days.  The expedited
procedures  set  forth  in Rule 51 et seq.  of the  Arbitration  Rules  shall be
applicable  to claims of less than  $1,000,000.  Arbitrators  shall be  licensed
attorneys  selected from the Commercial  Financial Dispute  Arbitration Panel of
the AAA. The parties hereto do not waive applicable Federal or state substantive
law except as provided herein.

     (c) Preservation and Limitation of Remedies.

                    (i)   Notwithstanding   the  preceding  binding  arbitration
               provisions,  the parties  hereto and to the other Loan  Documents
               agree to preserve, without diminution,  certain remedies that any
               such  Persons  may  exercise   before  or  after  an  arbitration
               proceeding  is brought.  Each such Person shall have the right to
               proceed in any court of proper  jurisdiction  or by  self-help to
               exercise or prosecute the following remedies, as applicable:  (i)
               all rights to foreclose  against any real or personal property or
               other security by exercising a power of sale or under  applicable
               law by judicial foreclosure including a proceeding to confirm the
               sale; (ii) all rights of self-help  including peaceful occupation
               of real property and collection of rents,  set-off,  and peaceful
               possession of personal property;  (iii) obtaining  provisional or
               ancillary  remedies including  injunctive relief,  sequestration,
               garnishment,  attachment,  appointment  of receiver and filing an
               involuntary  bankruptcy proceeding;  and (iv) when applicable,  a
               judgment by confession of judgment. Any claim or controversy with
               regard to any party's entitlement to such remedies is a Dispute.

                    (ii)  Each  party  hereto  and to the other  Loan  Documents
               agrees that it shall not have a remedy of  punitive or  exemplary
               damages against any other party hereto or any other Loan Document
               in any Dispute  and hereby  waives any right or claim to punitive
               or exemplary damages such party has now or which may arise in the
               future in  connection  with any  Dispute,  whether the Dispute is
               resolved by arbitration or judicially.

     (d)  JURY  TRIAL.  THE  PARTIES  HERETO  AND TO THE  OTHER  LOAN  DOCUMENTS
ACKNOWLEDGE THAT BY AGREEING TO BINDING ARBITRATION THEY HAVE IRREVOCABLY WAIVED
ANY RIGHT THEY MAY HAVE TO A JURY TRIAL WITH REGARD TO A DISPUTE.

     SECTION 6.10  Counterparts;  Effectiveness.  This Agreement may be executed
in any  number of  counterparts  and by  different  parties  hereto in  separate
counterparts,  each of which when so executed  shall be deemed to be an original
and shall be binding upon all parties,  their successors and assigns, and all of
which taken together shall constitute one and the same agreement.

     SECTION 6.11 Release and Termination.

     (a) Upon any sale,  lease,  transfer  or other  disposition  of any item of
Collateral  by any Assignor in accordance  with the terms of the Loan  Documents
(other than sales of  Collateral in the ordinary  course of business  consistent
with past  practices),  the Collateral  Agent will, at such Assignor's  expense,
execute and deliver to such  Assignor  such  documents  as such  Assignor  shall
request to evidence the release of such item of Collateral  from the  assignment
and security interest granted hereby.

     (b) This Agreement shall remain in effect from the Closing Date through and
including the date upon which all Obligations  shall have been  indefeasibly and
irrevocably  paid and satisfied in full and the Commitments  terminated and upon
such date the Security Interest granted hereby shall terminate and all rights to
the Collateral shall revert to the Assignors. Upon any such termination, (i) the
Collateral  Agent shall promptly  assign,  release,  transfer and deliver to the
Assignors the  Collateral  held by it hereunder,  all  instruments of assignment
executed  in  connection  therewith,  together  with  all  monies  held  by  the
Collateral  Agent or any of its  agents  hereunder,  free and clear of the Liens
hereof and (ii) the Agents and the Lenders will promptly  execute and deliver to
the Assignors  such  documents  and  instruments  (including  but not limited to
appropriate  UCC  termination  statements)  as the  Assignors  shall  request to
evidence such termination in each such case at the expense of the Grantors.

     SECTION 6.12 Entire Agreement.  This Agreement and the other Loan Documents
constitute the entire agreement and  understanding  among the parties hereto and
supersedes any and all prior agreements and understandings, oral or written, and
any contemporaneous  oral agreements and understandings  relating to the subject
matter hereof and thereof.
