ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS.

On  June  9,  1999,  we  acquired  System  Resources   Corporation  ("SRC"),  an
information  technology government  contractor.  We acquired SRC through a stock
purchase by our wholly owned  subsidiary,  Titan  Technologies  and  Information
Systems  Corporation  ("Titan  Technologies").  We will be  accounting  for this
transaction as a purchase.  We and the former  stockholders  of SRC will file an
election under the Internal Revenue Code to have the transaction  taxed as if it
were a sale of assets for federal tax  purposes.  The terms of the  purchase are
set forth in a Stock Purchase  Agreement  dated June 9, 1999, by and among Titan
Technologies,  SRC and the SRC stockholders, a copy of which is filed as Exhibit
2.1. We refer you to the stock  purchase  agreement for  additional  information
about the terms and conditions of the transaction. On June 10, 1999, we issued a
press release  announcing  the signing of the stock  purchase  agreement and the
closing of the  acquisition.  We are  incorporating  the press release into this
Form 8-K, and a copy has been attached as Exhibit 99.1.

We purchased all of the SRC stock for an aggregate of  $33,000,000  in cash paid
at  closing,  less a  $500,000  holdback,  and an  aggregate  of  $2,000,000  in
promissory notes which bear interest at 7% per annum and become fully payable on
June 9, 2000.  The  purchase  price is subject to a working  capital  adjustment
based  upon an  audit  of the  closing  balance  sheet  to be  completed  by our
auditors.  SRC had  stockholder's  equity of  approximately  $11,400,000  on its
interim  closing  balance  sheet.  In  addition,   we  agreed  to  pay  the  SRC
stockholders  one-half of approximately  $1,500,000 in SRC receivables aged more
than 720 days to the extent that any of those  receivables are collected  within
two years following the closing date.

We used borrowings  from our $75 million term loan,  which is a component of our
$190 million credit facility,  to fund the SRC  acquisition.  In connection with
the SRC  transaction,  our bank  syndicate,  with The Bank of Nova Scotia as the
administrative  agent,  amended and increased our existing credit facility.  The
credit  facility  includes a $55 million line of credit for working  capital and
general  corporate  purposes,  $60  million  in lines  of  credit  dedicated  to
acquisitions  and  the  $75  million  term  loan  referred  to  above.  We  used
approximately $5 million on the term loan to retire SRC's outstanding bank debt.

SRC, which is headquartered in Boston,  Massachusetts and has 10 offices located
in the United States,  principally  acts as a provider of  information  systems,
solutions and services,  primarily for U.S. government agencies.  SRC's business
base includes aviation and airport systems,  security,  logistics automation and
command and  control.  SRC will  continue  to devote its assets to its  existing
business base,  including future expansion.  In order to realize the anticipated
benefits of this  acquisition,  we must  efficiently  integrate  and combine the
operations  of  Titan   Technologies  and  SRC.  The  process  of  rationalizing
government  contracting,   management  services,  administrative  organizations,
facilities,  management information systems and other aspects of operations will
present a  significant  challenge to the  management  of the two  companies.  We
cannot  assure you that this  integration  process will be successful or that we
will fully realize the anticipated  benefits of the SRC acquisition.  Dedication
of our resources to the integration of SRC may detract attention from day-to-day
business of both Titan  Technologies and SRC. We have completed six acquisitions
of  information  technology  defense  contractors  during the past 18 months and
continue to pursue  other  acquisitions.  The  dedication  of  resources  to the
integration of SRC may also detract  attention from our integration  efforts for
our other acquisitions and our other ongoing operations.

The   difficulties   of  integration  may  be  increased  by  the  necessity  of
coordinating geographically separated organizations,  integrating personnel with
disparate business  backgrounds and combining different  corporate cultures.  We
cannot assure you that there will not be substantial  costs  associated with the
integration  process,  that such  activities  will not result in a  decrease  in
revenues  or that  there  will not be other  material  adverse  effects of these
integration efforts.

                                    Agreement

         Now,  Therefore,  in  consideration  of the foregoing  premises and the

         2.2 Allocation of Purchase Price. At the Closing,  Buyer shall pay each
Stockholder  an amount in cash  equal to the  product  of (i) the  Stockholder's

equal to the number of Shares held by such  Stockholder  on the Closing  Date as

                  (b)  Following  completion  of the  audit in  accordance  with
Section 2.3(d),  the principal  amount of the Notes shall be adjusted based upon
any  adjustments  to the  calculation  of Excess  Working  Capital or  Deficient
Working  Capital,  if any,  made  pursuant to Section  2.3(d).  If the principal
amount  of the Notes is  adjusted,  then the  interest  accruals  shall  also be
adjusted so that interest accrues on the adjusted  principal amount of the Notes

shall audit the  Unaudited  Interim  Balance  Sheet for  conformity to generally

changes to any method of accounting or accounting practice, such as depreciation
methods, used by SRC in preparing the Unaudited Interim Balance Sheet so long as
such methods and practices are in accordance  with GAAP,  consistently  applied.
Any  adjustment  to the  Unaudited  Interim  Balance  Sheet  proposed  by Arthur
Andersen llp shall be subject to review by SRC's auditors, Ernst & Young llp. If
the  opinions  of Arthur  Andersen  llp and  Ernst & Young llp  differ as to the
necessity of the  adjustment,  a third  auditing firm mutually  agreeable to the

adjustment  will be made to the Notes unless the  aggregate  effect of the audit

days included in the calculation of Excess Accounts Receivable are not collected
prior to the date of maturity of the Notes or if any unbilled fee retainages and
rate variances included in the calculation of Excess Accounts Receivable are not
collected  within 270 days of the Closing  Date,  then the  uncollected  amounts
shall be deducted  dollar for dollar from and offset against first the principal
of the Notes (pro rata), and then against any accrued and unpaid interest on the
Notes (pro rata).  If the  principal  amount of the Notes is adjusted,  then the
interest  accruals  shall  also be  adjusted  so that  interest  accrues  on the
adjusted  principal  amount of the Notes from the Closing Date. The Stockholders
shall  exchange the original Notes for new Notes  reflecting any  adjustments to
principal.  All other terms and  conditions of such Notes will remain  unchanged
(except for changes in accrued interest).

         2.5 Excess Accounts Receivable.  At Closing, SRC shall deliver to Buyer
a  detailed   schedule  setting  forth  by  contract  each  billed  or  unbilled
receivable,  each  unbilled  retainages  for  completed  contracts and each rate
variances for completed  contracts included in SRC's Excess Accounts  Receivable
and SRC's Old Excess  Accounts  Receivable,  which shall be  attached  hereto as
Schedule 2.5.  Following the Closing,  SRC, Buyer or Parent shall administer the
collection  of the  Excess  Accounts  Receivable  and  the Old  Excess  Accounts
Receivable  using  reasonable  billing and collection  practices to collect such
receivables  within a reasonable  period of time given the nature and age of the
receivables  and,  in  the  case  of the  receivables  in  the  Excess  Accounts
Receivable,  the terms of the Notes.  Neither  SRC,  Buyer nor any  affiliate of
Buyer  shall  act  as  a  fiduciary  of  the  Stockholders  in  collecting  such
receivables.  SRC shall  maintain  records with respect to its collection of all
Excess  Accounts  Receivable  and the Old  Excess  Accounts  Receivable  and its
out-of-pocket  collection  costs specific to such receivables and shall send the
Stockholders  a monthly  report of all such  collections  and  collection  costs
during  the  preceding  month.  The  Stockholder  Representative  may  contact a
designated  representative  of Buyer to discuss any questions  about the monthly
reports.  Upon the request of the  Stockholder  Representative,  Buyer will meet
with such representative quarterly in San Diego, California (or such other place
as is mutually  agreed to by the Stockholder  Representative  and the designated
representative of Buyer),  at a mutually  convenient date and time to review the

Receivable.) SRC shall pay to the Stockholders  (pro rata) the Collection Amount

certification shall be presented on or before April 15 of each of 2000, 2001 and
2002) of the amount of Old Excess  Accounts  Receivable  collected  during  such
period,   net  of  the  accrued   out-of-pocket   costs  of  collection,   which
certification  shall be done in conjunction with Buyer's annual financial audits
for the fiscal years ending December 31, 1999,  2000 and 2001.  Buyer may offset
any amount due to the Buyer  under  Section  2.4  against  any amount due to the

     4.  Representations  and  Warranties  of SRC.  Except  as set  forth in the
disclosure  schedules  attached  hereto (each a  "Schedule,"  collectively,  the
"Disclosure Schedule"), SRC and each of the Stockholders, jointly and severally,
represents and warrants to Buyer, as of the Closing Date, as follows:

         4.1  Organization  and Standing.  SRC is a corporation  duly organized,
validly  existing and in good  standing  under the laws of the State of Delaware
and is qualified or licensed to do business  and is in good  standing  under the
laws of  each of the  States  listed  on  Schedule  4.1.  SRC has all  requisite
corporate  power and all  necessary  governmental  approvals  to own,  lease and
operate its  properties  and assets,  and to carry on its  business as presently
conducted.  SRC is qualified or licensed to do business in all  jurisdictions in
which the nature of its  business or  properties  requires  such  qualification,
except where the failure to so qualify will not cause a material  adverse effect
on the business,  assets or financial  condition of SRC.  Except as disclosed in
Schedule 4.1, SRC has not conducted  business  under, or otherwise used, for any
purpose or in any jurisdiction any fictitious name,  assumed name, trade name or
other name other than "System Resources Corporation."

         4.2 No  Subsidiaries.  Except as set forth on Schedule  4.2, SRC has no
direct  or  indirect  subsidiaries  and does  not own or  control,  directly  or
indirectly,  any interest in any other  corporation,  association,  partnership,
joint venture or other business entity.  SRC has not agreed and is not obligated
to  make  any  future  investment  in  or  capital  contribution  to  any  other
corporation, association, partnership, joint venture or other business entity.

         4.3  Authorization.  The  Stockholders  have all  requisite  power  and
authority to enter into this Agreement, to sell and transfer the Shares pursuant
to this  Agreement and to carry out and perform all of their  obligations  under
the terms of this  Agreement.  All corporate  action on the part of SRC, if any,
and all  actions  on the part of SRC's  officers,  directors,  Stockholders  and
security holders that are necessary for the authorization,  execution,  delivery
and performance of the Agreement have been taken.  The Agreement,  when executed
and delivered,  shall constitute the legal and binding obligation of SRC and the
Stockholders,  enforceable  against SRC and the Stockholders,  respectively,  in
accordance  with  its  terms,  except  as  limited  by  applicable   bankruptcy,
insolvency,  reorganization,  moratorium  or other laws of  general  application
relating to or affecting  enforcement  of creditor's  rights and by rules of law
governing specific performance, injunctive relief or other equitable remedies.

         4.4 Title to Stock; Encumbrances. The Stockholders are the true, lawful
record and beneficial  owners of the Shares being  transferred and sold to Buyer
hereunder,  with no restrictions on the Stockholders' voting rights or rights of
transfer or  disposition  pertaining  to such  Shares,  except as may be imposed
under applicable securities laws, and the Shares constitute all of the shares of
capital stock of SRC owned  beneficially or of record by the Stockholders.  None
of the Shares is subject to any voting trust or other  agreement or  arrangement
with respect to the voting thereof. Upon the Closing,  Buyer will own all of the
outstanding  shares of capital  stock of SRC free and clear of any lien or other
Encumbrances  (as defined in Section 4.30).  All  outstanding  shares of capital
stock of SRC have been issued in compliance with applicable  securities laws and
other  applicable  Legal  Requirements  (as  defined  in  Section  4.30)  and in
compliance with all requirements of applicable  Contracts (as defined in Section
4.30).

         4.5 No Breach,  Etc. The execution  and delivery of this  Agreement and
all  documents  and  certificates  to be  delivered  hereunder  by SRC  and  the
Stockholders in connection with the transactions contemplated hereby do not, and
the  performance  and   consummation  by  SRC  and  the  Stockholders  of  their
obligations  hereunder will not result in any conflict with, breach or violation
of or  default,  termination,  forfeiture  or  Encumbrance  under  any  terms or
provisions of SRC's Certificate of Incorporation or Bylaws,  any statute,  rule,
regulation,  judicial or governmental  decree, order or judgment or any material
agreement,  lease or other instrument or other  obligation,  to which SRC or the
Stockholders  are a party or to which SRC's assets or any  Stockholders'  assets
are subject and do not require any consent, approval, authorization or permit of
or filing with or notification to any  Governmental  Body (as defined in Section
4.30),  other than a filing under the Hart-Scott  Rodino Antitrust  Improvements
Act of 1976,  as amended  (the "HSR Act"),  or,  except as disclosed in Schedule
4.5, require any notice,  consent or approval of any third party,  including any
party to a Material Contract (as defined in Section 4.16(a)).

         4.6  Capitalization.  The  authorized  capital stock of SRC consists of
Fifteen  Million  (15,000,000)  shares of Common Stock,  no par value,  of which
Seven Million One Hundred Fifty Thousand  (7,150,000) shares of Common Stock are
and will be,  immediately prior to the Closing,  issued and outstanding.  All of
such shares of  outstanding  Common Stock are owned by the  Stockholders  in the
amounts  indicated on the Schedule of  Stockholders  and are being sold to Buyer
hereunder.   No  other  shares  of  capital  stock  or  securities  of  SRC  are
outstanding. All of the issued and outstanding shares of Common Stock of SRC are
duly authorized,  validly issued, fully paid and nonassessable,  were not issued
in violation or breach of any preemptive or similar rights, and have been issued
in compliance with all applicable  federal and state  securities laws. There are
no outstanding options,  warrants,  convertible securities or other rights under
which SRC is or may become obligated to issue,  assign or transfer any shares of
its  capital  stock,  and none of the  foregoing  will  arise as a result of the
execution  or  performance  of the  Agreement or the  transactions  contemplated
herein. Except as set forth in Schedule 4.6, SRC has never repurchased, redeemed
or otherwise  reacquired any shares of its capital stock or other securities and
none of the shares of capital  stock or  securities of SRC is subject to a right
of repurchase in favor of SRC.

         4.7 Taxes.

                  (a) All tax  returns  required  to be filed by or on behalf of
SRC with any  Governmental  Body on or before the  Closing  Date or for  periods
occurring on or before the Closing Date (i) have been or will be filed when due,
including  extensions  and (ii) have  been,  or will be when  filed,  accurately
prepared in all  material  respects.  SRC has,  within the time  (including  any
extensions  of applicable  due dates) and in the manner  prescribed by law, paid
all Taxes that are due and payable.  SRC's  Financial  Statements (as defined in
Section 4.8) fully accrue all  liabilities  for Taxes required to be recorded in
accordance  with GAAP  consistently  applied with respect to all periods through
the dates  thereof  in  accordance  with  GAAP  consistently  applied,  with the
exception of any federal built-in gains tax resulting from the Election. "Tax or
Taxes" shall mean all federal,  state,  county, city,  municipality,  assessment
districts,  local  and  foreign  taxes and other  assessments  and  governmental
charges of a similar nature owed by SRC  including,  but not limited to, income,
sales, use, excise,  personal and real property  (tangible and intangible) taxes
imposed by any  Government  Body (as defined in Section 4.30)  (whether  imposed
directly or through withholding), including interest, penalties and additions to
Tax applicable thereto, but excluding any other Tax payable by the Stockholders.

                  (b) No  claim  or  legal  proceeding  is  pending  or has been
threatened  against or with  respect to SRC in respect of any Tax.  There are no
unsatisfied liabilities for Taxes (including liabilities for interest, additions
to tax and penalties  thereon and related  expenses) with respect to any written
notice of deficiency or similar document received by SRC. There are no liens for
Taxes upon any of the assets of SRC,  except liens for current Taxes not yet due
and payable.  No extension or waiver of any limitation  period applicable to any
SRC Tax  returns  has been  granted  by SRC (or any  other  person)  and no such
extension or waiver has been  requested.  Since  January 1, 1993,  no SRC return
relating to Taxes has been examined or audited by any  Governmental  Body except
as disclosed on Schedule 4.7(b).

                  (c) At all times from  October  1, 1989  through  the  Closing
Date, SRC has been an S corporation  for federal tax purposes within the meaning
of Section  1361(a)(1) of the Code and has used the last Friday prior to the 1st
day of October as its taxable year.  Prior to Closing,  SRC and the Stockholders
have not taken any action that has or shall result in the  termination  of SRC's
status as an S corporation  within the meaning of Section 1361(a)(1) of the Code
or imposition of a tax on SRC under the  provisions of Section 1374 of the Code.
Except as  disclosed  on  Schedule  4.7(c),  as of the date  hereof  SRC has not
conducted  any  business  in any  state or  political  subdivision  in which the
disposition  of any of its assets  including  goodwill in a transaction in which

political  subdivision of a corporate level tax. Except as disclosed on Schedule
4.7(c),  SRC does not conduct any  business  which is a historic  business of, a
continuation of, or successor to any business which was previously  conducted by
another  corporation  or any other entity  which was subject to a United  States
corporate  level tax on its gain or income  including a tax imposed by reason of
the  provisions  of  Section  1374  and  1375 of the  Code,  or any  predecessor
provisions thereto.  SRC has never acquired any asset,  including goodwill,  the
basis of which was  determined  in whole or in part by reference to the basis of
the  asset  in the  hands of a C  corporation  within  the  meaning  of  Section
1361(a)(2)  of the Code or S  corporation  subject to the  provisions of Section
1374 of the Code or  predecessor  provisions  thereto.  Except as  disclosed  on
Schedule 4.7(c), SRC has no accumulated earnings and profits.

                  (d) Except for  potential  Tax on built-in  gain under Section
1374 of the Code as  disclosed  on Schedule  4.7(c),  which shall not exceed the
Excluded  Liability (as defined in Section 8.1), SRC will not be liable from and
after the Closing for any Tax under Section 1374 of the Code in connection  with
the deemed sale of assets caused by the Election.

licenses) does not infringe, violate or misappropriate any intellectual property
rights of any third party. SRC is the owner or licensee of all right,  title and
interest in and to all of the SRC  Intellectual  Property  free and clear of all
liens and  Encumbrances,  and has the right to use without  further payment to a
third party all of the SRC Intellectual  Property. To the best knowledge of SRC,
there are no actual or claimed  infringements,  violations or  misappropriations
existing  by or against  any third  party with  respect to the SRC  Intellectual
Property.  To the best knowledge of SRC, all of the SRC Intellectual Property is
valid and  enforceable,  and  neither  SRC nor any  Stockholder  has,  by act or
failure to act, including without limitation,  by failure to attach any required
notice or failure to pay fees,  transferred  any rights to the SRC  Intellectual
Property into the public domain.  SRC is not making use of any SRC  Intellectual
Property  in  connection  with the  business of SRC in which any present or past
employee,  partner,  Stockholder,  licensor, licensee or agent of SRC has or has
claimed an interest,  and to the best  knowledge of SRC, there are no facts that
could reasonably be expected to give rise to such a claim.

Contract  is  valid  and in full  force  and  effect,  and,  to the  best of the
knowledge of SRC, is enforceable by SRC in accordance with its terms, subject to

written notice or other communication  regarding any actual or possible material
violation or breach of, or default under, any Material  Contract;  and

any of its material rights under any Material Contract; .

Material Contract.

                  (e) The Contracts  identified in Schedule 4.16(a) and Schedule

         4.18 Employee and Labor Matters; Benefit Plans.

                  (a)  Schedule  4.18(a)(i)   identifies  each  salary,   bonus,

benefit of any employee of SRC ("Employee"). Schedule 4.18(a)(ii) identifies the
schedule  of  payments   under  SRC's   deferred   compensation   and  incentive
compensation  programs.  Except as specified in Schedule 4.18(a)(i) and payments
under SRC's 401(k) plan, or as otherwise  required by law, SRC has no obligation
to any current or former  employee or  beneficiary of such  individuals  for any
deferred compensation or other deferred payments.

                  (b) Except as set forth in Schedule  4.18(a)(i),  SRC does not
maintain,  sponsor  or  contribute  to,  and,  has not at any  time in the  past
maintained,  sponsored or contributed to, any employee  pension benefit plan (as
defined in Section 3(2) of the Employee  Retirement Income Security Act of 1974,
as amended  ("ERISA"),  whether or not excluded  from  coverage  under  specific
Titles or Merger  Subtitles  of ERISA) for the  benefit of  Employees  or former
Employees (a "Pension Plan").

                  (c) SRC  maintains,  sponsors  or  contributes  only to  those
employee welfare benefit plans (as defined in Section 3(1) of ERISA,  whether or
not excluded from coverage under specific  Titles or Merger  Subtitles of ERISA)
for the benefit of Employees or former Employees which are described in Schedule
4.18(a) (the "Welfare Plans"), none of which is a multiemployer plan (within the
meaning of Section 3(37) of ERISA).

                  (d) With respect to each Plan,  SRC has prepared and delivered
to Buyer:

                          (i)  an  accurate  and  complete  copy  of  such  Plan
(including all amendments thereto);

                          (ii) an accurate and complete copy of completed annual

third party funding vehicle, an accurate and complete copy of the trust or other
funding agreement  (including all amendments  thereto) and accurate and complete
copies of the most recent financial statements thereof;

                          (v)  accurate  and  complete  copies of all  Contracts
relating  to  such  Plan,  including  service  provider  agreements,   insurance
contracts,   minimum  premium  contracts,   stop-loss   agreements,   investment

keeping agreements; and

                          (vi) an accurate and complete  copy of the most recent
determination  letter received from the Internal Revenue Service with respect to
such Plan (if such Plan is intended to be qualified  under Section 401(a) of the
Code).

                  (e) SRC is not and has never been  required to be treated as a
single  employer  with any other Person  under  Section  4001(b)(1)  of ERISA or
Section  414(b),  (c), (m) or (o) of the Code. SRC has never been a member of an
"affiliated service group" within the meaning of Section 414(m) of the Code. SRC
has never made a complete or partial  withdrawal from a  multiemployer  plan, as
such term is  defined  in  Section  3(37) of  ERISA,  resulting  in  "withdrawal
liability," as such term is defined in Section 4201 of ERISA (without  regard to
subsequent  reduction or waiver of such  liability  under either Section 4207 or
4208 of ERISA).

                  (f) SRC does not have any plan or  commitment  to  create  any
additional Welfare Plan or any Pension Plan, or to modify or change any existing
Welfare  Plan or Pension  Plan (other than to comply with  applicable  law) in a
manner that would affect any Employee.

                  (g) No Welfare Plan provides death, medical or health benefits
(whether or not insured)  with respect to any current or former  Employee  after
any such  Employee's  termination  of service  (other than (i) benefit  coverage
mandated by applicable  law,  including  coverage  provided  pursuant to Section
4980B of the Code, (ii) deferred compensation benefits accrued as liabilities on
the Unaudited  Interim Balance Sheet,  and (iii) benefits the full cost of which
are borne by current or former Employees (or the Employees' beneficiaries)).

                  (h) With respect to each of the Welfare Plans  constituting  a
group  health plan within the meaning of Section  4980B(g)(2)  of the Code,  the
provisions of Section 4980B of the Code ("COBRA") have been complied with in all
material respects.

                  (i) Except as specified in Schedule 4.18(i), each of the Plans
has been operated and  administered in all material  respects in accordance with
applicable Legal Requirements, including but not limited to ERISA and the Code.

                  (j) Except as specified in Schedule 4.18(i), each of the Plans
intended to be qualified  under  Section  401(a) of the Code has received (or is
the subject of) a favorable determination from the Internal Revenue Service, and
neither  SRC nor any of the  Stockholders  is aware of any  reason  why any such
determination letter could reasonably be expected to be revoked.

                  (k)  Except  as set forth in  Schedule  4.18(k),  neither  the
execution,  delivery or performance of this Agreement,  nor the  consummation of
the  sale  of  Shares  or any of the  other  transactions  contemplated  by this
Agreement,  will  result in any  payment by SRC  (including  any  bonus,  golden
parachute or severance payment) to any current or former Employee or director of
SRC (whether or not under any Plan), or materially increase the benefits payable
under any Plan, or result in any  acceleration of the time of payment or vesting
of any such benefits.

                  (l) Schedule 4.18(l) contains a list of all salaried Employees
of SRC as of the date of this Agreement, and correctly reflects, in all material
respects,  their  salaries,  any other  compensation  payable to them (including
compensation  payable  pursuant to bonus,  deferred  compensation  or commission
arrangements),  their dates of employment and their positions.  Schedule 4.18(l)
also contains a list of all Employees of SRC with  security  clearances  and the
level  of  such  security  clearance.  SRC is  not a  party  to  any  collective
bargaining  contract or other  Contract with a labor union  involving any of its
Employees.  Except as specified in Schedule 4.18(l),  all of SRC's employees are
"at will" employees.

                  (m)  Except  as set  forth on  Schedule  4.18(m)  there are no
Employees currently on disability or other leave.

                  (n) SRC is in  compliance  in all material  respects  with all
applicable Legal Requirements and Contracts  relating to employment,  employment
practices,  wages,  bonuses and terms and  conditions of  employment,  including
employee  compensation  matters including without  limitation Legal Requirements
respecting employment discrimination,  workers' compensation, family and medical
leave,  the  Immigration  Reform and Control  Act, and  occupational  safety and
health  requirements,  and  has  not  and is not  engaged  in any  unfair  labor
practice.

                  (o)   Neither   SRC  nor  any   Shareholder   has   made   any
representation  or  promise  to any  employee  of SRC  regarding  any  benefits,
compensation  or other  payments that might be paid or distributed by SRC to any
employee of SRC as a result of the  consummation of any transaction  involving a
change of control of SRC, including the transaction contemplated hereby.

                  (p) SRC has good labor relations generally with its Employees.

                  (q) All persons  classified by SRC as independent  contractors
do satisfy and have satisfied the  requirements of law in effect at that time to
be so classified,  and SRC has fully and accurately  reported their compensation
on IRS  Forms  1099  when  required  to do so,  except  to the  extent  that any
misclassification  of any such person will not have a material adverse effect on
SRC.

                  (r)  There is no  charge  or  compliance  proceeding  actually
pending or, to the best knowledge of SRC threatened against SRC before the Equal
Employment  Opportunity  Commission  or any  state,  local,  or  foreign  agency
responsible for the prevention of unlawful employment practices.

         4.19  Compliance  with Laws. SRC is, and at all times during the period
prior  to the  date  hereof  SRC has  been,  in  material  compliance  with  all
applicable  Legal  Requirements.  Except as set forth on  Schedule  4.19,  since

Governmental  Body  regarding  any material  violation  of, or failure to comply
with, any Legal Requirements.

         4.20   Governmental   Authorizations.    SRC   has   all   Governmental
Authorizations  necessary to enable SRC to conduct its business in the manner in
which business is currently  being  conducted,  except where any failure to have
such  Governmental  Authorizations  has not had and  will  not  have a  material
adverse effect on SRC. SRC is, and at all times has been, in compliance with the
material terms and requirements of such Governmental Authorizations. SRC has not
received any notice or other  communication from any Governmental Body regarding
(a) any actual or  possible  violation  of or failure to comply with any term or
requirement  of any  Governmental  Authorization,  or (b) any actual or possible
revocation, withdrawal, suspension, cancellation, termination or modification of
any Governmental Authorization.  "Governmental Authorization" shall mean any (a)
permit,  license,  consent,  certificate,   franchise,  permission,   clearance,
registration,   qualification,   or  authorization  issued,  granted,  given  or
otherwise made available by or under the authority of any  Governmental  Body or
pursuant to any Legal Requirement; or (b) right under any Government Contract.

         4.21  Related  Persons.  Except as set forth in Schedule  4.21,  (a) no
Stockholder, director, officer, former director or officer of SRC, or any member
of the  immediate  family of such person or any entity  owned or  controlled  in
whole or in part by any such  person or any trust  for the  benefit  of any such
person or any member of such person's  immediate family  ("Related  Party") has,

has entered into, or has had any direct or indirect  financial  interest in, any
material Contract, transaction or business dealing with or involving SRC; (d) no
Related  Party  is  competing,  or  has  at  any  time,  competed,  directly  or
indirectly,  with SRC; and (e) no Related  Party has any claim or right  against
SRC (other than rights to receive  compensation  for  services  performed  as an
employee of SRC).

         4.22  Insurance.  Schedule  4.22  sets  forth (a) an  accurate  summary
description of each insurance policy providing  coverage for liability  exposure
(including  policies  providing  property,   casualty,  liability  and  workers'
compensation  coverage  and  bond  and  surety  arrangements)  to  which  SRC is
currently,  or has been during the past three years, a party, a named insured or
otherwise  the  beneficiary  of  coverage  and (b) all  insurance  loss  runs or
worker's  compensation  claims  received for the past three policy  years.  With
respect to each such insurance  policy:  to SRC's  knowledge,  (a) the policy is
legal, valid, binding,  enforceable and in full force and effect; (b) there will
be no breach or other violation of the policy  resulting from this  transaction;
and (c) SRC is not in material  breach or default with respect to each policy it
maintains  (including  with  respect to the payment of premiums or the giving of
notices),  and no event has  occurred  which,  with notice or the lapse of time,
would constitute such a breach or default, or permit  termination,  modification
or acceleration, under each such policy.

         4.23  Real  Property;  Owned or  Leased.  Schedule  4.23  sets  forth a
complete and accurate  description  of each parcel of real property  owned by or
leased to SRC.  All the  leases  listed on  Schedule  4.23 are valid and in full
force and effect, and there does not exist any default or event that with notice
or lapse of time, or both,  would constitute a default under any of these leases
and no person (except SRC and the owner of such real property under the terms of
the applicable lease) has any right of possession to such leased property or any
part  thereof.  SRC  owns  clear  and  marketable  title,  free of any  liens or
Encumbrances,  to all improvements and fixtures located on these real properties
and reflected on SRC's Unaudited  Interim  Balance Sheet.  There is presently no
pending or, to SRC's knowledge, contemplated condemnation of any of the property
listed on Schedule 4.23 or any part  thereof,  and SRC has made no commitment to
any governmental or  quasi-governmental  entity or to any other person or entity
which  relates to such  property  or  imposes  upon SRC or SRC's  successors  or
assigns any  obligation to pay or contribute  property or money or to construct,
install or  maintain  any  improvements  on or off such  property.  There are no
violations by SRC of any law,  including  any  building,  planning or zoning law
relating  to any owned or leased  real  properties  that  would  have a material
adverse effect on SRC or its financial condition, assets, liabilities, business,
or operations.

         4.24  Environmental  Matters.  SRC is in  compliance  in  all  material
respects with all applicable  Environmental  Laws, which compliance includes the
possession by SRC of all permits and other  Government  Authorizations  required
under  applicable   Environmental  Laws,  and  compliance  with  the  terms  and
conditions   thereof.   SRC  has  not  received  any  written  notice  or  other
communication,  whether from a Governmental  Body,  citizens group,  employee or
otherwise,  that  alleges  that  SRC is not or was not in  compliance  with  any
Environmental Law, and, to the best knowledge of SRC, there are no circumstances
that may prevent or interfere with SRC's compliance with any  Environmental  Law
in the future. During the term of any of SRC's leases, no current or prior owner
of any  property  leased  or  controlled  by SRC has  notified  SRC  that it has
received any written notice or other communication,  whether from a Governmental
Body, citizens group,  employee or otherwise,  that alleges that such current or
prior owner or any occupier of the property is or was not in compliance with any
Environmental  Law. SRC is not required to obtain any Government  Authorizations
pursuant to Environmental  Laws in connection with the operation of its business
as currently  conducted.  Except as disclosed on Schedule 4.24, none of the real
properties leased by SRC pursuant to the Leases (including,  without limitation,
soils, surface water and groundwater located at such properties) is contaminated
with any Materials of Environmental  Concern.  To the best knowledge of SRC none
of  the  property  leased  by  SRC  (other  than  pursuant  to  the  Leases)  is
contaminated with any Materials of Environmental  Concern.  "Environmental  Law"
means any  federal,  state,  local or  foreign  Legal  Requirement  relating  to
pollution or protection of human health or the  environment  (including  ambient
air, surface water, ground water, land surface or subsurface strata),  including
any law or regulation relating to emissions,  discharges, releases or threatened
releases of Materials of  Environmental  Concern,  or otherwise  relating to the
manufacture,   processing,  distribution,  use,  treatment,  storage,  disposal,
transport or handling of  Materials  of  Environmental  Concern.  "Materials  of
Environmental  Concern" include  chemicals,  pollutants,  contaminants,  wastes,
toxic substances,  petroleum and petroleum products and any other substance that
is now or hereafter  regulated by any  Environmental  Law or that is otherwise a
danger to health, reproduction or the environment.

         4.25  Corporate  Records  SRC  has  delivered,  or made  available  for
inspection,  to Buyer  accurate  and  complete  copies of (1) SRC's  articles of
incorporation  and  bylaws,  including  all  amendments  thereto;  (2) the stock
records of SRC; and (3) the minutes and other records of the formal  meeting and
proceedings (including any actions taken by written consent or otherwise without
a meeting) of the Stockholders, the board of directors of SRC and all committees
of the board of  directors of SRC.  There have been no formal  meetings or other
proceedings of the Stockholders,  the board of directors of SRC or any committee
of the board of directors of SRC that are not fully reflected in such minutes or
other records. The stock records and minutes books are accurate,  up to date and
complete in all material respects.

         4.26 Full Disclosure. No statement by the Stockholders or SRC contained
in this Agreement,  or the Exhibits,  Schedules or other attachments  hereto, or
any written  certificate  furnished or to be furnished to Buyer pursuant  hereto
(when read together)  contains any untrue  statement of a material fact or omits
to state a material  fact  necessary in order to make the  statements  contained
herein or therein not misleading in light of the circumstances  under which they
were made.

         4.27 Brokers. Other than Granite Hill Advisors,  llc, no broker, finder
or  investment  banker is  entitled to any  brokerage,  finder's or other fee or
commission  in  connection  with  this  Agreement  based on any  arrangement  or
agreement made by or on behalf of SRC or the Stockholders.

         4.28 Disallowable  Expense Items. Except as disclosed on Schedule 4.28,
all costs related to any Related Party (as defined in Section 4.21),  including,
but not limited,  to compensation,  consultation fees, life insurance  premiums,
auto  allowances,  business meals,  related party facility cost and any facility
purchase  options  have  been  properly  classified  as  unallowable  costs  for
Government Contract accounting purposes as described below in Schedule 4.28.

         4.29 Year 2000 Compliance. Except as set forth in Schedule 4.29, all of
SRC's products and internal systems are designed to be used prior to, during and
after the year 2000, and are Year 2000 Compliant.  At Buyer's request,  SRC will
provide the results of the testing to date of all of SRC's  products and systems

with Buyer's compliance plan.

severally and not jointly,  represents and warrants to Buyer,  as of the Closing

financial condition of Buyer.

         6.2 Corporate Power;  Authorization.  Buyer has all requisite legal and
corporate  power and  authority to enter into the  Agreement  and to execute and

Documents.  All corporate action on the part of Buyer and all action on the part
of its officers and  directors  necessary for the  authorization,  execution and
delivery of this  Agreement and the  Transaction  Documents by Buyer and for the
performance of Buyer's obligations  hereunder and thereunder has been taken, and
the Agreement and the Transaction  Documents,  when duly executed and delivered,
shall constitute the valid and binding  obligation of Buyer enforceable  against
Buyer in accordance with its terms, except as limited by applicable  bankruptcy,
insolvency,  reorganization,  moratorium  or other laws of  general  application
relating to or affecting  enforcement  of creditor's  rights and by rules of law

conflict  with,  breach or violation of or default,  termination,  forfeiture or
Encumbrance   under  any  terms  of   provisions  of  Buyer's   Certificate   of
Incorporation or Bylaws, any statute, rule, regulation, judicial or governmental
decree,  order or judgment or any material agreement,  lease or other instrument

date of grant equally over four years, on an annual basis.

         7.7 Intentionally Left Blank.







     8.Additional Agreements.

         8.1 Payment of Taxes.  SRC has paid any corporate  level Taxes required
to be paid by SRC in respect of all periods on or prior to the Closing Date that
were due and payable on or prior to the Closing  Date with the  exception of the
federal BIG Tax and any corporate level state taxes accrued in the normal course
of SRC's business  (without  regard to the  Election).  Except for any corporate
level  Taxes  paid  by  SRC in  accordance  with  the  preceding  sentence,  the
Stockholders  have paid, or (to the extent not yet due and payable) will pay, in
a timely fashion,  all Taxes required to be paid that are properly includible in
their personal tax returns  attributable to their ownership of Shares in respect
of all  periods  on or prior to the  Closing  Date.  Such Taxes  shall  include,
without  limitation,  all Taxes for which the Stockholders are liable due to the
status of SRC as an S  corporation  for  federal  income tax  purposes  (and any
analogous  provisions  of state or local  law) and,  in  particular,  such Taxes
arising as a result of the  Election  (as defined in Section 8.2) other than the
Excluded  Liability and any corporate level Taxes required to be paid in respect
to all periods on or prior to the Closing  Date that are not yet due and payable
as of the Closing Date. The Stockholders shall reimburse Buyer or SRC within ten
(10) days of any  payment by Buyer or SRC for the  payment  of, any and all such
Taxes of SRC or the Stockholders attributable to any taxable period ending on or
prior  to the  Closing  Date,  other  than up to  $630,000  attributable  to any
built-in  gain incurred  under  Section 1374 of the Code in connection  with the
deemed sale of assets caused by the Election  ("Excluded  Liability")  and other
than any Tax liability  accrued on the Unaudited  Interim Balance Sheet (such as
liabilities for employer taxes).  Prior to the Closing,  the parties shall agree
upon the amount of built-in-gain  based upon the recommendations of the parties'
outside  consultants and shall  determine the amount of the Excluded  Liability,
which shall not exceed $630,000.

         8.2 Tax  Election.  Buyer and each  Stockholder  shall jointly make the
elections  provided for by Sections 338(a) and 338(h)(10) of the Code and Treas.
Reg. ss.  1.338(h)(10)-1  (and any comparable election under state or local law)
with  respect to the  purchase  of the Shares by Buyer  (each,  an  "Election").
Immediately  following  the Closing,  Buyer shall deliver a signed and completed
Form 8023 to the Stockholders and the Stockholders shall execute and deliver the
form to Buyer at the Closing.  Also, Buyer and Stockholders shall cooperate with
each other to take all actions necessary and appropriate  (including filing such
additional forms, returns,  elections,  schedules, and other documents as may be
required)  to effect  and  preserve a timely  Election  in  accordance  with the
provisions of Treas. Reg. ss.  1.338(h)(10)-1  (or any comparable  provisions of
state or local tax law) or any  successor  provisions.  Buyer and  Seller  shall
report the purchase by Buyer of the Shares pursuant to the Agreement  consistent
with the Elections (and any  comparable  election under state or local tax laws)
and shall take no position  inconsistent  therewith  in any tax  return,  or any
proceeding before any taxing authority or otherwise.

         8.3 Tax  Allocations.  In connection  with the  Elections,  immediately
after the  Closing  or within  thirty  (30) days of the  Closing,  the Buyer and
Stockholders  shall act together in good faith to (i) determine and agree upon a
"Modified  Aggregate  Deemed  Sales Price" of SRC (within the meaning of, and in
accordance with, Treas. Reg. ss. 1.338(h)(10)-1(f)) and (ii) determine and agree
upon the proper  allocations  (the  "Allocations")  of the  "Modified  Aggregate
Deemed Sales  Price"  among the  respective  assets of SRC (in  accordance  with
Section 338(b)(5) of the Code and Treasury regulations promulgated  thereunder).
Buyer and the Stockholders  shall (i) be bound by such  determinations  and such
Allocations for purposes of determining  any taxes,  (ii) prepare and file their
tax returns on a basis consistent with such  determinations and such Allocations
and (iii) take no position inconsistent with such determinations and Allocations
on any applicable tax return,  in any proceeding  before any taxing authority or
otherwise.  In the event  that any such  Allocation  is  disputed  by any taxing
authority,  the party receiving  notice of the dispute shall promptly notify the
other party hereto concerning resolution of the dispute. Any liability for taxes
arising from the  Elections  (other than the Excluded  Liability  which shall be
payable by SRC) shall be borne by the Stockholders, jointly and severally.

         8.4 Tax Matters.

                  (a) No later  than 30 days  prior to any  applicable  due date
(including  extensions),  the Stockholders shall timely prepare, or caused to be
prepared, and deliver to Buyer for its review and approval, which approval shall
not be  unreasonably  withheld,  proposed  federal and state  income tax returns
(including tax return  extensions,  as necessary) of SRC for the taxable periods
of SRC  ending  on or prior  to the  Closing.  Such  proposed  returns  shall be
prepared consistent with the elections applicable to prior returns of SRC and no
new or different  elections  for tax purposes  other than the Election  shall be
made in  connection  with such returns.  Upon Buyer's  approval of such proposed
returns  (and  extensions),  SRC shall timely  file,  or cause to be filed,  the
approved returns and the  Stockholders  shall pay, or cause to be paid, when due
all income taxes,  if any, other than the Excluded  Liability,  relating to such
returns.  If the  approved  return  includes  any  overpayment  of taxes  due to
overpayment of the Estimated Tax Payment,  then, when SRC receives the refund or
otherwise obtains the benefit of the overpayment through an offset against Taxes
then payable,  SRC will remit the overpayment to the Stockholders (pro rata). If
Buyer does not approve of any return as proposed by Stockholders,  Buyer and the
Stockholders together with their respective tax advisors will attempt to resolve
any  disputed  issues  within  the 30 day review and  approval  period.  If such
disputes  cannot be resolved,  then SRC shall timely  prepare and file a request
for extension for such disputed returns, and the parties shall promptly select a
nationally   recognized  "Big  Five"  accounting  firm  (which  is  neither  the
accountants  to Buyer nor the  Stockholders  nor SRC) to  resolve  all  disputed
matters.  If the parties cannot agree on a Big Five accounting  firm, each party
shall rank all eligible  firms from most  acceptable to least  acceptable  (with
most acceptable  being designated 1, next most 2, and so on) and the firm having
the lowest combined  numerical value shall be deemed the mutually selected firm,
whose resolution of disputed issues shall be final and binding upon all parties.

                  (b) The Buyer shall have the right to  participate  in and the
Stockholders shall have the right to control,  at the Stockholders' own cost and
expense,  any income tax audit or administrative or court proceeding relating to
income tax returns of SRC for  periods  prior to  Closing.  Notwithstanding  the
foregoing,  the  Stockholders  shall not be  permitted to take any action in, or
settle any claim  arising  out of,  such audit or  proceeding  without the prior
written consent of Buyer, which consent shall not be unreasonably withheld.

                  (c) After  the  Closing,  the  Stockholders  and  Buyer  shall
provide  each other with such  cooperation  and  information  relating to SRC as
either party  reasonably may request in filing any federal or state or local Tax
return  (or  amended  return),  determining  any tax  liability,  conducting  or
defending any audit or other  proceeding in respect of Taxes or effectuating the
terms of this Agreement.

     9. Indemnification.

         9.1 Survival of Representations, Etc.

                  (a) Subject to the  indemnification  limitations  set forth in
Section 9.3, the  representations  and  warranties  made by SRC  (including  the
representations and warranties set forth in Section 4) shall survive the Closing
and  shall  expire on the  first  anniversary  of the  Closing  Date;  provided,
however,  that if, at any time  prior to the first  anniversary  of the  Closing
Date, any Parent Indemnitee (defined below),  acting in good faith,  delivers to
any of the Stockholders a written notice alleging the existence of an inaccuracy
in or a breach of any of the  representations  and  warranties  made by SRC (and
setting forth in reasonable detail the basis for such Parent Indemnitee's belief

                  (b) The representations, warranties, covenants and obligations
of SRC and the  Stockholders,  and the rights and remedies that may be exercised

and after the  Closing,  the  Stockholders,  jointly and  severally,  shall hold
harmless  and  indemnify  each of the Parent  Indemnitees  from and  against any
Damages  (regardless  of whether such  Damages  relate to any third party claim)

with any of the representations,  warranties,  covenants and agreements given or
made by SRC or the Stockholders in this Agreement,  the Disclosure  Schedules or

accrued on the Unaudited  Interim  Balance Sheet as Other Accrued  Liabilities);
(iii) any alleged  obligation of SRC or its Stockholders for investment  banking
or other  fees  arising  from the sale of the Shares  other than the  investment
banking fees payable to Granite Hill Advisors llc as disclosed on Schedule 4.27;
(iv) any  Damages  to SRC  resulting  from  the  failure  to have  the  Deferred
Compensation Trust administered in accordance with the trust documents;  (v) any
Legal Proceeding  relating to any claim under clause "(i)",  "(ii)",  "(iii)" or
"(iv)" above (including any Legal Proceeding  commenced by any Parent Indemnitee

                  (b)  The  Stockholders  acknowledge  and  agree  that  if  SRC
suffers, incurs or otherwise becomes subject to any Damages as a result of or in
connection  with any  inaccuracy in or breach of any  representation,  warranty,
covenant or  obligation,  then (without  limiting any of the rights of SRC as an
Parent Indemnitee) Buyer shall also be deemed, by virtue of its ownership of the
stock of SRC, to have  incurred  Damages as a result of and in  connection  with
such inaccuracy or breach.

         9.3 Threshold; Ceiling.

                  (a) Except as set forth in this  Section 9.3 the  Stockholders
shall not be required to make any  indemnification  payment  pursuant to Section
9.2 for any inaccuracy in or breach of any of their  representations,  covenants
or  obligations  set forth  herein  until  such time as the total  amount of all
Damages that have been directly or indirectly suffered or incurred by any one or
more of the  Parent  Indemnities,  or to  which  any  one or more of the  Parent
Indemnities  has or have  otherwise  become  subject,  exceeds  $400,000  in the
aggregate  (excluding (i) any liability for Taxes payable pursuant to Section 8,
other than the Excluded Liability; and (ii) any liability under clauses (ii) and
(iv) of Section 9.2(a), or any Legal Proceeding relating thereto; (collectively,
the "Excluded Claims"),  each of which shall be payable without any deductible).
If  the  total  amount  of  such  Damages  exceeds  $400,000,  then  the  Parent
Indemnities  shall be entitled to be  indemnified  against and  compensated  and
reimbursed only for the portion of such Damages  exceeding  $400,000.  Any legal
fees  incurred  in  defending  any  action,  claim,  or  proceeding,  brought or
threatened  by those  persons  listed on  Schedule  9.3  against SRC shall count
against  the  deductible,  even  though  the  claim  itself  is not  subject  to
indemnification.  If any  Damages  are  incurred  due to a claim as set forth in
Section  9.2(a)(iii),  the first  $200,000 in Damages  shall  count  against the
$400,000 deductible to the extent of any remaining deductible.  The Stockholders
shall jointly and severally indemnify each of the Parent  Indemnitees,  pursuant
to Section 9.2(a)(iii) to the extent such Damages exceed $200,000 and the extent
of the portion of any of the first  $200,000  in Damages  that cannot be set off
against the deductible because of prior claims against the deductible.

                  (b) The  indemnification  liability of Stockholders under this
Section 9 shall not exceed  $2,625,000  (excluding any interest payable pursuant
to Section 9.8).

         9.4 No  Contribution.  Each  Stockholder  waives,  and acknowledges and
agrees  that he shall not have and shall not  exercise  or assert (or attempt to
exercise or assert),  any right of  contribution,  right of  indemnity  or other
right or remedy against SRC in connection with any indemnification obligation or
any other  liability to which he may become subject under or in connection  with
this Agreement.

         9.5  Indemnification by Buyer.  Subject to the limitations set forth in
Section 9, the Buyer will indemnify and hold harmless the Stockholders and their
heirs,  executors  and legal  representatives  from and  against (i) any and all
Damages  arising  out  of any  misrepresentation  or  breach  of or  default  in
connection with any of the representations, warranties, covenants and agreements
given or made by the Buyer in this  Agreement,  the Disclosure  Schedules or any
exhibit or schedule to this  Agreement  and (ii) any claim by any person who was
an employee of SRC on the Closing  Date  against the  Stockholders  based solely
upon actions  taken or not taken by Buyer or SRC following the Closing Date with
respect  to such  person's  salary  or  benefits  as an  employee  at SRC or any
affiliated  company of Buyer or such person's  employment  following the Closing
Date (so long as any claim is not  based  upon any  promise  or  commitment  for
ongoing  employment  by SRC prior to the Closing Date or its  Stockholders),  so
long as the claim is not based  upon a breach of  promise  disclosed  in Section
4.18(o); provided however (i) any claim for indemnity shall be asserted prior to
the expiration of the survival  period set forth in Section 9.1.  Recovery under
Section 9.5 shall be the exclusive remedy under this Agreement for any claim for
monetary  damages arising out of any breach or default in connection with any of
the  representations,  warranties,  covenants  or  agreements  set forth in this
Agreement,  the  Disclosure  Schedules  or  any  exhibit  or  schedule  to  this
Agreement;  unless such breach or default is the result of willful misconduct or
fraud on the part of the Buyer.

         9.6 Defense of Third Party  Claims.  In the event of the  occurrence of
any event that any party  asserts is an  indemnifiable  event  pursuant  to this
Section 9, the party claiming  indemnification  (the "Indemnified  Party") shall
provide  prompt  notice to the party  required to provide  indemnification  (the
"Indemnifying   Party"),   specifying  in   reasonable   detail  the  facts  and
circumstances  with respect to such claim or Legal  Proceeding and the basis for
which indemnification is available hereunder.  If such claim or Legal Proceeding
involves the claim of any third  party,  the  Indemnifying  Party shall have the
right to control the defense or settlement (using counsel reasonably  acceptable
to the Indemnified  Party);  provided,  however,  that (a) the Indemnified Party
shall be entitled to participate in the defense of such Legal  Proceeding at its
own expense,  (b) the Indemnifying Party shall obtain the prior written approval
of the Indemnified  Party (which approval shall not be unreasonably  withheld or
delayed)  before  entering  into any  settlement  of such Legal  Proceeding  if,
pursuant to or as a result of such settlement,  injunctive or other non-monetary
relief would be imposed against the Indemnified  Party, and (c) the Indemnifying
Party shall not be entitled to control (but shall be entitled to  participate at
its own expense in the defense of), and the Indemnified  Party shall be entitled
to have sole  control  over,  with respect to the defense or  settlement  of any
claim or Legal  Proceeding to the extent such claim or Legal Proceeding seeks an
order,  injunction  or other  equitable  relief  or a  declaration  against  the
Indemnified  Party which,  if successful,  would  materially  interfere with the
business, operations, assets, condition (financial or otherwise) or prospects of
the  Indemnified  Party  or  SRC or to the  extent  that  such  claim  or  Legal
Proceeding is also brought against the  Indemnifying  Party and the Indemnifying
Party and the Indemnified Party have conflicting interests in the claim or Legal
Proceeding,  including different  defenses,  provided that the Indemnified Party
shall provide written notice to the Indemnifying Party of its election to assume
control  over  the  defense  of  such  claim   pursuant  to  this  Section  9.6.
Notwithstanding anything to the contrary in the foregoing, in no event shall the
Stockholders,  their heirs,  executors or legal  representatives  be entitled to
control  the  defense of any Legal  Proceeding  against  the Parent  Indemnitees
involving  the  claim of any  Governmental  Body with  which  any of the  Parent
Indemnitees  are  conducting  business  at the time  such  Legal  Proceeding  is
brought;  provided,  however,  that the Stockholders shall be entitled, at their
own expense, to participate (in a non-leading role) in such Legal Proceedings.

non-renewal  of such  policy due to the claim  experience  or any  increases  in
premiums or deductibles on such policy resulting from the claim experience). Any
Indemnified  Party  shall  act in good  faith and in a  commercially  reasonable
manner to minimize  that amount of any Damages it may  otherwise  suffer  (other
than  pursuant to any third party  claim  covered by Section  9.6) to the extent
such minimization is within its actual control and will not materially interfere
with the business,  operations,  assets,  condition  (financial or otherwise) or
prospects of the Indemnified Party.

intended to provide any rights or remedies to any person  other than the parties
hereto and their respective successors and assigns (if any).

         10.15  Entire  Agreement.  This  Agreement  and  the  other  agreements
referred  to herein and the letter  agreement  dated of even date  herewith  set
forth the entire  understanding  of the parties  hereto  relating to the subject
matter hereof and thereof and supersede all prior agreements and  understandings
among or between any of the parties  relating to the subject  matter  hereof and
thereof.

         10.16 Construction.

                  (a) For  purposes  of this  Agreement,  whenever  the  context
requires:  the singular  number shall  include the plural,  and vice versa;  the
masculine  gender shall  include the feminine and neuter  genders;  the feminine
gender shall  include the masculine  and neuter  genders;  and the neuter gender
shall include the masculine and feminine genders.

                  (b) The parties hereto agree that any rule of  construction to
the effect that  ambiguities are to be resolved against the drafting party shall
not be applied in the construction or interpretation of this Agreement.

                  (c) As  used  in  this  Agreement,  the  words  "include"  and
"including,"  and  variations  thereof,  shall  not be  deemed  to be  terms  of
limitation,  but rather  shall be deemed to be  followed  by the words  "without
limitation."

Except as otherwise  indicated,  all  references in this Agreement to "Sections"
and  "Exhibits" are intended to refer to Sections of this Agreement and Exhibits
to this Agreement.

         10.17  Negotiation of Disputes.  Except as provided in Sections  2.3(d)
and 8.4, if a dispute arises between the parties relating to the  interpretation
or performance of this Agreement or any other agreement or instrument that is an
exhibit to this Agreement or the grounds for the  termination  thereof,  and the
parties cannot  resolve the dispute  within thirty days of a written  request by
either party to the other, such dispute shall be referred to the Chief Financial
Officer of Buyer and the Stockholders' Agent for resolution.  Such persons shall
hold a meeting to attempt in good faith to negotiate a resolution of the dispute
prior to pursuing  other  available  remedies.  If within 10 business days after
such meeting,  the Chief Financial Officer of Buyer and the Stockholders'  Agent
have not  succeeded in  negotiating  a resolution  of the dispute,  such dispute
shall be submitted to arbitration as set forth in Section 10.18 below.

         10.18  Arbitration.  Except as  provided  in  Sections  2.3(d) and 8.4,
disputes  that have not been  successfully  resolved  pursuant to Section  10.17
above shall be submitted to final and binding arbitration under the then current
commercial  rules  and  regulations  of  JAMS  Endispute  ("JAMS")  relating  to
voluntary  arbitration  in San  Diego,  California.  The  arbitration  shall  be
conducted by three  arbitrators,  one selected by each party to the  arbitration
and one selected by  arbitrators  appointed by the parties.  If the  arbitrators
cannot agree on a third  arbitrator,  the third  arbitrator shall be selected in
accordance  with the JAMS rules.  If a party fails to  designate  an  arbitrator
within the time limits set by the JAMS  rules,  the  arbitrator  selected by the
other party shall be the sole arbitrator.  All arbitrators must be knowledgeable
in the subject matter at issue in the dispute.  Each party shall  initially bear
its own costs and legal fees  associated  with such  arbitration and the parties
shall  split  the  cost of the  arbitrators.  The  prevailing  party in any such
arbitration  shall be  entitled to recover  from the other party the  reasonable
attorneys'  fees,  costs  and  expenses  incurred  by such  prevailing  party in
connection with such  arbitration.  The decision of the  arbitrator(s)  shall be
final and may be sued on or  enforced by the party in whose favor it runs in any
court of  competent  jurisdiction  at the option of the  successful  party.  The
rights and  obligations of the parties to arbitrate any dispute  relating to the
interpretation  or  performance  of  this  Agreement  or  the  grounds  for  the
termination  thereof,  shall  survive  the  expiration  or  termination  of this
Agreement for any reason. The arbitrator(s) shall be empowered to award specific
performance,  injunctive relief and other equitable remedies as well as damages,
but shall not be empowered to award  punitive or exemplary  damages or award any
damages in excess of any limitations set forth in this Agreement.

$149,650                                                            June 9, 1999
                                                           San Diego, California

         FOR  VALUE  RECEIVED,   TITAN  TECHNOLOGIES  AND  INFORMATION   SYSTEMS
CORPORATION, a Delaware corporation ("Borrower"),  hereby promises to pay to the
order of THE SAMIR A.  DESAI  1998  IRREVOCABLE  TRUST  DATED  FEBRUARY  2, 1998
("Holder"),  in lawful money of the United States of America and in  immediately
available  funds,  the  principal  sum of One Hundred  Forty Nine  Thousand  Six
Hundred  Fifty  Dollars  ($149,650.00)  (the "Loan")  together  with accrued and
unpaid interest thereon, payable on the date and in the manner set forth below.

         This Promissory Note is one of the Notes referred to in and is executed
and delivered in connection  with that certain Stock  Purchase  Agreement  dated
June 9, 1999, by and among Borrower,  Holder,  the other  stockholders of System
Resources Corporation,  a Delaware corporation ("System Resources  Corporation")
(as the same may from time to time be  amended,  modified or  supplemented,  the
"Stock Purchase  Agreement") and System Resources  Corporation.  All capitalized
terms used herein and not  otherwise  defined  herein shall have the  respective
meanings given to them in the Stock Purchase Agreement.

1.                Repayment.  The outstanding  principal  amount of the Loan and
                  all  accrued  and  unpaid  interest  thereon  shall be due and
                  payable  on June 9, 2000 or upon  acceleration  of the Note in
                  accordance  with  the  terms  hereof  ("Maturity  Date").  The
                  principal amount of this Note is subject to further adjustment
                  as set forth in Section 2.3 of the Stock Purchase Agreement.

2.                Interest Rate.  Borrower  further  promises to pay interest on
                  the  outstanding  principal  amount  hereof  (as  adjusted  in
                  accordance  with the Stock Purchase  Agreement)  from the date
                  hereof until payment in full,  which interest shall be payable
                  at the rate of seven  percent  (7%) per  annum or the  maximum
                  rate  permissible by law (which under the laws of the State of
                  California  shall  be  deemed  to  be  the  laws  relating  to
                  permissible rates of interest on commercial loans),  whichever
                  is  less.  Interest  shall  be  calculated  on the  basis of a
                  365-day year for the actual number of days elapsed.

3.                Place of  Payment.  All  amounts  payable  hereunder  shall be
                  payable  by  delivery  of a check to the  Stockholders'  Agent
                  under the Stock Purchase Agreement.

4.                Application  of  Payments.  Payments  on this  Note  shall  be
                  applied  first to  accrued  interest,  and  thereafter  to the
                  outstanding principal balance hereof.

5.                Offset.   Borrower   shall  be  entitled  to  offset   certain
                  uncollected  accounts receivable against the principal balance
                  of the  Note  in  accordance  with  Section  2.4 of the  Stock
                  Purchase  Agreement and Borrower and any Titan Indemnitees (as
                  defined in the Stock Purchase  Agreement) shall be entitled to
                  offset Damages  against the outstanding  principal  balance of
                  the Note in accordance with the offset procedures set forth in
                  the Stock Purchase Agreement.

6.                Default.  The following shall  constitute a default under this
                  Note (a "Default"):  (i) Borrower's failure to pay in full the
                  amount due under this Note,  including  any accrued and unpaid
                  interest,  on the date the same  becomes  due and  payable  or
                  within five (5) calendar days  thereafter;  (ii) the making of
                  an  assignment by Borrower for the benefit of creditors or the
                  application  or consent by  Borrower to the  appointment  of a
                  trustee or receiver for its property; (iii) the appointment of
                  a trustee or receiver for Borrower,  which trustee or receiver
                  is  not   discharged   within   sixty  (60)  days  after  such
                  appointment;   or  (iv)   the   institution   of   bankruptcy,
                  reorganization,   insolvency  or  similar  proceedings  by  or
                  against Borrower, which if instituted against it, is consented
                  to  or  not  dismissed  within  sixty  (60)  days  after  such
                  institution.  Upon the occurrence of Borrower's  Default,  all
                  unpaid  principal and accrued interest shall, at the option of
                  Holder, be accelerated and become due and payable in full.

7.                Prepayment.  Borrower may prepay this  Promissory  Note at any
                  time either in whole or in part without penalty.

8.                Waiver;   Payment  of  Fees  and  Expenses.   Borrower  waives
                  presentment  and  demand  for  payment,  notice  of  dishonor,
                  protest and notice of protest of this Note,  and shall pay all
                  costs  of  collection   when  incurred,   including,   without
                  limitation,   reasonable  attorneys'  fees,  costs  and  other
                  expenses.   The  right  to  plead  any  and  all  statutes  of
                  limitations  as a defense to any demands  hereunder  is hereby
                  waived to the full extent permitted by law.

9.                Governing  Law.  This Note shall be governed by, and construed
                  and  enforced  in  accordance  with,  the laws of the State of
                  California,  excluding  conflict of laws principles that would
                  cause the application of laws of any other jurisdiction.

10.               Successors  and  Assigns.  The  provisions  of this Note shall
                  inure to the  benefit of and be binding  on any  successor  to
                  Borrower.  This Note is not a negotiable instrument and Holder
                  shall not be entitled to assign the Note, except for estate or
                  tax planning  purposes,  without the prior written  consent of
                  Borrower  and in the  case  of any  assignment,  including  an
                  assignment for estate or tax planning purposes,  the agreement
                  by the  assignee to become  subject to the terms of this Note,
                  the  offset  provisions   referenced  herein  and  the  offset
                  provisions referenced in the Stock Purchase Agreement.

                               FORM OF GUARANTEE

                                    GUARANTEE


         As an  inducement  to and in  consideration  of SAMIR A.  DESAI AND THE
SAMIR A. DESAI 1998 IRREVOCABLE TRUST dated February 2, 1998 (each a "Creditor",
and collectively the "Creditors")  granting credit under that certain Promissory
Note of even date herewith (the "Note") to TITAN  TECHNOLOGIES  AND  INFORMATION
SYSTEMS CORPORATION, a Delaware corporation ("Debtor") of which the undersigned,
THE  TITAN  CORPORATION,  a  Delaware  corporation  ("Guarantor"),  is the  sole
stockholder, Guarantor, intending to be legally and equitably bound, does hereby
unconditionally  and irrevocably  guarantee to the Creditors,  their  respective
successors and assigns, prompt and full payment of all indebtedness of Debtor to
the Creditors (the  "Guarantied  Indebtedness")  resulting from the Note arising
out of the purchase of capital stock of System Resources Corporation pursuant to
that certain Stock  Purchase  Agreement  dated of even date herewith (the "Stock
Purchase  Agreement") by and among System Resources  Corporation,  the Creditors
and Debtor, regardless of any invalidity, irregularity, unenforceability or lack
of genuineness of any document creating the Guarantied Indebtedness.

         The liability of Guarantor shall be absolute and unconditional, and its
obligations  hereunder shall not in any way be diminished,  limited or otherwise
affected by (1) the liquidation or dissolution of Debtor; (2) any adverse change
in the  condition  (financial  or  otherwise)  of Debtor;  (3) the  discharge or
release of Debtor for any reason, including,  without limitation, as a result of
bankruptcy, receivership or similar proceedings; or (4) any waiver or indulgence
granted by the  Creditors  in the  exercise  of any of its  rights and  remedies
against or in respect of any failure in the performance by Debtor.

         Guarantor  hereby  expressly  waives  notices  of  creation,   advance,
increase,  existence,  extension, renewal, modification or assignment of, and of
any indulgence with respect to, the Guarantied  Indebtedness.  Guarantor  hereby
expressly  waives  presentment,  demand,  notice  of  nonpayment,  dishonor  and
protest, notice of the amount of the Guarantied Indebtedness  outstanding at any
time,  notice of any change in financial  condition of any person  liable on the
Guarantied  Indebtedness or any part thereof,  all other notices  respecting the
Guarantied  Indebtedness  and diligence and  promptness in bringing suit against
Debtor on the Guarantied Indebtedness,  or any part thereof. The maturity of the
Guarantied  Indebtedness  and any part  thereof may be  accelerated,  increased,
extended  or renewed  one or more times by the  Creditors  in their  discretion,
without  notice to  Guarantor.  No notice to or demand on  Guarantor in any case
shall, of itself,  entitle Guarantor to any other or further notice or demand in
similar or other circumstances.

         Guarantor  hereby  expressly  waives any and all rights of subrogation,
reimbursement,  indemnification,  exoneration,  contribution  or any other claim
which  Guarantor  may now or hereafter  have against  Debtor or any other person
directly or contingently liable for the Guarantied  Indebtedness,  or against or
with respect to Debtor's property (including without limitation any property now
or hereafter securing the Guarantied  Indebtedness),  arising from the existence
or performance of this Guarantee.  If Guarantor receives any amount in violation
of this paragraph and its obligations  hereunder,  whether matured or unmatured,
are not paid in full, such amount shall be deemed to have been paid to Guarantor
for the benefit of, and held in trust for the  benefit  of, the  Creditors,  and
shall  forthwith  be paid to the  Creditors  to be credited  and applied to such
obligations.

         The  Creditors  are not required to seek  collection or take any action
against Debtor as a condition to the Guarantor's  liability and obligation under
this  Guarantee,  and the  Creditors  need not  institute  suit or exhaust their
remedies  against,  any security  deposit or collateral  or any other  guarantee
prior to enforcing this Guarantee against the Guarantor.

         In the  event  that the  Creditors  are  forced  to  retain  attorneys,
collection  agencies or other outside parties,  to effect collection pursuant to
this  Guarantee,  Guarantor  agrees to be liable,  in addition to the Guarantied
Indebtedness, for the payment of reasonable attorneys' fees, collection fees and
all other costs incurred in effecting such collection.

         Guarantor is a corporation duly organized, validly existing and in good
standing under the laws of the State of Delaware and has all requisite corporate
power and authority and is entitled to carry on its  respective  business as now
being conducted by it and to own, lease or operate its respective  properties as
and in the places where such business is now conducted  and  properties  are now
owned, leased or operated.  Guarantor is qualified or licensed to do business in
all  jurisdictions  in which the nature of its business or  properties  requires
such  qualification,  except  where the  failure to so qualify  would not have a
material  adverse  effect on the  business  assets  or  financial  condition  of
Guarantor.

         Guarantor has all requisite  legal and corporate power and authority to
enter into this  Guarantee  and to carry out and perform all of its  obligations
under the terms of this Guarantee. All corporate action on the part of Guarantor
and all  action on the part of its  officers  and  directors  necessary  for the
authorization, execution and delivery of this Guarantee by Guarantor and for the
performance of Guarantor's  obligations hereunder and thereunder has been taken,
and this Guarantee, when duly executed and delivered, shall constitute the valid
and binding obligation of Guarantor  enforceable against Guarantor in accordance
with  its  terms,  except  as  limited  by  applicable  bankruptcy,  insolvency,
reorganization,  moratorium or other laws of general application  relating to or
affecting  enforcement  of  creditor's  rights  and by  rules  of law  governing
specific performance, injunctive relief or other equitable remedies.

         The execution and delivery of this Guarantee by Guarantor does not, and
the performance and consummation by Guarantor of its obligations  hereunder will
not  result  in  any  conflict  with,  breach  or  violation  of  provisions  of
Guarantor's   Certificate  of  Incorporation  or  Bylaws,  any  statute,   rule,

thereunder.  Section 1542 of the Civil Code of the State of California  provides
as follows:

                  A  general  release  does not  extend to claims
         which the creditor  does not know or suspect to exist in
         his favor at the time of executing the release, which if
         known  by  him  must  have   materially   affected   his
         settlement with the debtor.

Each  Releasor  also hereby waives the benefits of, and any rights such Releasor
may have under,  any statute or common law  principle  of similar  effect in any
jurisdiction.

4. REPRESENTATIONS AND WARRANTIES. Each Releasor represents and warrants that:

                  (a) such Releasor has not assigned,  transferred,  conveyed or
         otherwise  disposed of any Claim against any of the  Releasees,  or any
         direct or indirect interest in any such Claim, in whole or in part;

                  (b) to the best of such Releasor's knowledge,  no other person

                  (c) no Associated  Party of such Releasor has or had any Claim
         against any of the Releasees;

                  (d) to the best of such  Releasor's  knowledge,  no Associated
         Party of such  Releasor  will in the future have any Claim  against any
         Releasee that arises directly or indirectly from or relates directly or
         indirectly to any circumstance,  agreement, activity, action, omission,
         event or matter  occurring  or  existing  on or before the date of this
         General Release;

         Associated Parties in accordance with its terms;

                  (g) there is no action, suit, proceeding, dispute, litigation,
         claim,  complaint or  investigation  by or before any court,  tribunal,
         governmental body, governmental agency or arbitrator pending or, to the
         best  of the  knowledge  of  such  Releasor,  threatened  against  such
         Releasor or any of such Releasor's  Associated  Parties that challenges
         or would  challenge the execution and delivery of this General  Release
         or the  taking  of any of the  actions  required  to be  taken  by such
         Releasor under this General Release;

                  (h) neither the execution and delivery of this General Release
         nor the  performance  hereof will (i) result in any violation or breach
         of any  agreement or other  instrument to which such Releasor or any of
         such Releasor's Associated Parties is a party or by which such Releasor
         or any of such Releasor's  Associated  Parties is bound, or (ii) result
         in a violation of any law, rule, regulation, treaty, ruling, directive,
         order,  arbitration award, judgment or decree to which such Releasor or

         delivery of this General Release or the performance hereof.

5.       MISCELLANEOUS.

                  (a) This General  Release sets forth the entire  understanding
         of the parties relating to the subject matter hereof and supersedes all
         prior  agreements  and  understandings  among  or  between  any  of the
         Releasors and Releasees relating to the subject matter hereof.

                  (b) If any  provision of this  General  Release or any part of
         any such  provision  is held under any  circumstances  to be invalid or
         unenforceable  in any  jurisdiction,  then (i) such  provision  or part
         thereof  shall,  with  respect  to  such   circumstances  and  in  such
         jurisdiction,  be deemed amended to conform to applicable laws so as to
         be valid and  enforceable  to the  fullest  possible  extent,  (ii) the
         invalidity or  unenforceability of such provision or part thereof under
         such  circumstances  and in such  jurisdiction  shall  not  affect  the
         validity or  enforceability of such provision or part thereof under any
         other  circumstances  or in any  other  jurisdiction,  and  (iii)  such
         invalidity or  enforceability  of such  provision or part thereof shall
         not affect the  validity or  enforceability  of the  remainder  of such
         provision or the validity or  enforceability  of any other provision of
         this General  Release.  If any provision of this General Release or any
         part  of  such  provision  is  held  to be  unenforceable  against  any
         Releasor,  then the  unenforceability of such provision or part thereof
         against  such  Releasor  shall not  affect the  enforceability  thereof
         against any other  Releasor.  Each provision of this General Release is
         separable from every other provision of this General Release,  and each
         part of each provision of this General  Release is separable from every
         other part of such provision.

                  (c) This General  Release  shall be  construed  in  accordance
         with,  and  governed  in all  respects  by,  the  laws of the  State of
         California (without giving effect to principles of conflicts of laws).

                  (d)  This   General   Release   may  be  executed  in  several
         counterparts,  each of which shall  constitute  an original  and all of
         which, when taken together, shall constitute one agreement.

                  (e) Each Releasor  shall execute  and/or cause to be delivered
         to each Releasee such instruments and other  documents,  and shall take
         such other  actions,  as such Releasee may  reasonably  request for the
         purpose of carrying out or evidencing  any of the actions  contemplated
         by this General Release.

                  (f) If any action or  proceeding  for the  enforcement  of any
         provision  hereof  is  initiated  by  any  Releasor  or  Releasee,  the
         prevailing  party shall be entitled  to recover  reasonable  attorneys'
         fees,  costs and  disbursements  to the extent  actually  incurred  (in
         addition  to any  other  relief to which  the  prevailing  party may be
         entitled).

                  (g) This General  Release shall be effective  with respect to,
         and shall be binding upon and  enforceable  against,  each Releasor who
         executes this General  Release,  regardless of whether any of the other
         Releasors executes this General Release.

                  (h)  Whenever  required by the context,  the  singular  number
         shall include the plural,  and vice versa;  the masculine  gender shall
         include the feminine and neuter  genders;  and the neuter  gender shall
         include the masculine and feminine genders.

                  (i) Any rule of  construction  to the effect that  ambiguities
         are to be resolved  against the drafting  party shall not be applied in
         the construction or interpretation of this General Release.

                  (j) As used in this General  Release,  the words "include" and
         "including," and variations thereof, shall not be deemed to be terms of
         limitation,  and shall be deemed to be followed  by the words  "without
         limitation."

                  Re:       System Resources Corporation

Ladies and Gentlemen:

         We have acted as special  counsel to System  Resources  Corporation,  a
Delaware corporation ("SRC"), and the Stockholders of SRC  ("Stockholders"),  in
connection  with the  Stock  Purchase  Agreement  dated as of June 9,  1999 (the
"Agreement")  by and among  SRC,  Titan  Technologies  and  Information  Systems
Corporation (the "Buyer"), and the Stockholders.

         This  opinion  is  delivered  to you  pursuant  to  Section  3.2 of the
Agreement.  Capitalized  terms used herein and not otherwise  defined shall have
the meanings given them in the Agreement.

         In  connection  with  this  opinion,  we  have  (i)  investigated  such
questions of law, (ii) examined such documents and records of SRC,  certificates
of public  officials and other  documents,  and (iii) received such  information
from  officers  or  representatives  of  SRC  as we  have  deemed  necessary  or
appropriate for the purposes of this opinion. We call your attention to the fact
that we have not represented  SRC on a day-to-day  basis with respect to various
contract and other matters.  Specifically,  we advise you that SRC has relied on
the advice of McKenna & Cuneo, LLP with respect to certain matters. Accordingly,
there may exist matters of a legal nature with respect to which we have not been
consulted or engaged.

         We  have  examined  the  following   documents  and  instruments   (the
"Transaction Documents"):

         (a)      An executed copy of the Agreement;

         (b) The form of Guaranty by The Titan Corporation (the "Parent") to the
Stockholders attached as an exhibit to the Agreement;

         (c) The form of  Promissory  Note  issued by the Buyer  attached  as an
exhibit to the Agreement;

         (d)  The  form  of  General  Release  attached  as an  exhibit  to  the
Agreement;

         (e) The form of Consulting  Agreement  with Samir A. Desai  executed in
connection with the Agreement; and

         (f) The form of Noncompetition and  Confidentiality  Agreement attached
as an exhibit to the Agreement.

         We have also reviewed SRC's  Certificate of  Incorporation,  as amended
(the  "Certificate"),  and By-laws (the  "By-laws");  and a certificate of legal
existence and good standing with respect to SRC issued by the Delaware Secretary
of State  dated May 11,  1999,  and  certificates  of  qualification  to conduct
business set forth on Schedule "A" attached hereto.

         We have assumed, without independently verifying such assumptions,  the
genuineness  of the  signatures  on all of the  documents  examined  by us,  the
authenticity of all documents  furnished for our  examination as originals,  and
the conformity to original documents of all documents furnished to us as copies,
including documents transmitted by telecopier.

         In  rendering  our  opinion,  we have assumed that the Buyer and Parent
have the power and authority and have taken the action  necessary to execute and
deliver  the  relevant  Transaction  Documents;   that  no  consent,   approval,
authorization,  declaration,  registration or filing by or with any governmental
agency,  authority,  commission,  board or bureau is required for such execution
and delivery by the Buyer and Parent in connection with the consummation by such
party of the transactions contemplated by the Transaction Documents other than a
filing  under the  Hart-Scott  Rodino  Antitrust  Improvements  Act of 1976,  as
amended,  and such other  consents as have been obtained by the Buyer and Parent
prior to the date  hereof;  and that the  Transaction  Documents  have been duly
executed  and  delivered by the Buyer and the Parent and  constitute  the legal,
valid, binding and enforceable obligations of the Buyer and the Parent.

         In rendering  this opinion as to factual  matters,  we have relied upon
the  accuracy  of  statements  made  to us by  officers  and  directors  of  SRC
(including  for this purpose  representations  and warranties of SRC made in the
Agreement),  and our review of such other documents and certificates of officers
or directors of SRC or of public  officials as we have deemed  necessary for the
purpose of giving this  opinion.  We have assumed  that,  as of the date hereof,
there  have  been no  changes  in  respect  of the  matters  set  forth  in such
certificates.  We have not made any other independent factual investigation with
respect to the matters  discussed  herein.  Further,  we have not made any other
independent  review or  investigation  of  instruments,  orders,  judgments,  or
decrees  by  which  SRC or its  properties  may be  bound,  nor have we made any
independent investigations of proceedings, if any, pending or threatened against
SRC.

         When  an  opinion  set  forth  is  given  to "our  knowledge",  or with
reference  to matters  "of which we are  aware" or "which  are known to us",  or
words of similar import,  the relevant  knowledge or awareness is limited to the
actual  knowledge or awareness  of the  individual  lawyers in the firm who have
participated directly in the specific transactions to which this opinion relates
and without any special or additional  investigation undertaken for the purposes
of this opinion.  In connection with the opinion expressed in Paragraphs 1 and 2
as to valid  existence,  corporate  good standing and  qualification  to conduct
business,   we  have  relied  solely  on  legal   existence  and  good  standing
certificates relating to SRC as referenced above.

         The  opinions  hereinafter  expressed  are  subject  to  the  following
qualifications:

         a.   the   application   and   effect   of   bankruptcy,    insolvency,
reorganization, moratorium, fraudulent or preferential transfer or conveyance or
other  similar  statutes,  rules,  regulations,  court  decisions  or other laws
relating to or affecting the enforcement of creditors' rights and remedies;

         b.  the   unavailability  or  limitations  on  the  availability  of  a
particular  right or remedy provided to the Buyer in the Transaction  Documents,
whether in a proceeding in equity or at law, as a result of the  application  of
the principles of equity,  as the  availability of equitable rights and remedies
is  subject  to and  within  the sole  discretion  of the  court  in  which  any
proceeding for enforcement may be brought; and

         c. the fact that  provisions  relating to  indemnification,  release or
waiver  (including,  without  limitation,  the waiver of certain  defenses,  the
waiver of stay and extension  laws and other  exemption and  redemption  rights)
contained in the  Transaction  Documents may be limited (i) by applicable  laws,
statutes or the policies  underlying such laws or statutes or (ii) by applicable
laws  rendering  unenforceable,  in whole or in part, (a) the release of a party
from,  the waiver of rights  against a party for,  or the  indemnification  of a
party  against,  liability for its own wrongful or negligent  acts under certain
circumstances or (b) any waiver or release contrary to public policy.

         Based upon and subject to the foregoing  limitations and qualifications
and those set forth below, we are of the opinion that:

         1. SRC has been duly incorporated and is a validly existing corporation
in corporate good standing  under the laws of the state of Delaware.  SRC has no
subsidiaries.

         2. SRC has the requisite  corporate  power to own or lease its property
and assets and to conduct its business as it is currently  being  conducted and,
to the best of our  knowledge,  is  qualified  as a  foreign  corporation  to do
business  and is in good  standing  in each  jurisdiction  in the United  States
listed on  Schedule  "A"  attached  hereto.  To our  knowledge,  except  for the
jurisdictions  listed on Schedule "A," there is no other  jurisdiction  in which
the  ownership of SRC's  property or the conduct of its business  requires  such
qualification,  except where the failure to so qualify would not have a material
adverse effect on SRC's assets,  financial  condition or operations (a "Material
Adverse Effect").

         3. The Stock Purchase Agreement has been duly authorized,  executed and
delivered by SRC and has been duly  executed and  delivered by the  Stockholders
and  constitutes  a valid and  binding  agreement  of SRC and the  Stockholders,
respectively,  enforceable  against SRC and the  Stockholders in accordance with
its terms.

         4. Immediately  prior to the Closing,  the authorized  capital stock of
SRC consisted of Fifteen  Million  (15,000,000)  shares of Common Stock,  no par
value, of which Seven Million One Hundred Fifty Thousand  (7,150,000)  shares of
Common  Stock are and will be,  immediately  prior to the  Closing,  issued  and
outstanding.  The Shares have been duly authorized,  validly issued,  fully paid
and  nonassessable.  To the  best of our  knowledge,  there  are no  outstanding
subscriptions,  options, warrants, rights to convert, capital stock equivalents,
stock  appreciation  rights or other rights to purchase or otherwise acquire any
of SRC's capital stock or other securities,  or rights under phantom stock plans
or similar plans or arrangements.

         5. Upon  delivery  of the  Shares to the Buyer and the  payment  of the
Purchase  Price for the Shares by the Buyer to the  Stockholders  in  accordance
with the  terms of the  Agreement,  the  Buyer  will be the  owner of all of the
Shares, free and clear of any adverse claim.

         6. There are no stock  transfer  taxes due and imposed upon transfer of
the Shares by the Stockholders to the Buyer.

         7. The  execution and delivery of the Stock  Purchase  Agreement by SRC
and the  Stockholders  and the  consummation  of the  transactions  contemplated
thereby do not violate any provision of SRC's  Certificate of  Incorporation  or
its Bylaws,  do not  constitute a default  under the  provisions of any material
agreement  known  to  us  to  which  the  Stockholders  (in  their  capacity  as
stockholders)  are a party or by which  the  Stockholders  are  bound  (in their
capacity  as  stockholders)  and,  do not  violate  or  contravene  (a),  to our
knowledge,  any  governmental  statute,  rule or  regulation  applicable  to the
Stockholders  or SRC,  or (b) any order,  writ,  judgment,  injunction,  decree,
determination  or award which has been entered  against the  Stockholders or SRC
and of which we are aware,  the violation or contravention of which would have a
Material Adverse Effect.

         8. To our knowledge,  there is no action,  proceeding or  investigation
pending or overtly  threatened  against the Stockholders or SRC before any court
or  administrative  agency that  questions  the  validity of the Stock  Purchase
Agreement or that would result, either individually or in the aggregate,  in any
Material Adverse Effect.

         9. All consents,  approvals,  authorizations or orders of, and filings,
registrations and qualifications  with any regulatory  authority or governmental
body in the United States required for the  consummation by the  Stockholders or
SRC of the  transactions  contemplated  by the  Agreements  have  been  made  or
obtained.

         We  are  counsel   admitted  to   practice  in  the   Commonwealth   of
Massachusetts,  and we express no opinion  with respect to the laws of any other
jurisdiction, other than the federal law of the United States of America and the
General  Corporation  Law  of  the  State  of  Delaware  and  the  laws  of  the
Commonwealth of  Massachusetts.  No opinion is expressed  herein with respect to
the qualification of the Note or the Guaranty under the securities or "blue sky"
laws of any state or foreign  jurisdiction,  nor is any opinion expressed herein
with respect to antitrust laws. We call your attention  specifically to the fact
that we are not admitted to practice in the State of Delaware. We have based our
opinion  with  respect  to  Delaware  law  on  our  examination  of  appropriate
certificates  from  officers  or  officials  of the  State of  Delaware,  and of
applicable  statutory  provisions  of  Delaware  corporate  law, as set forth in
unofficial compilations, and have made no investigation of regulations, rules or
cases  interpreting  or applying  those  statutory  provisions.  This opinion is
limited to the present laws and to the facts as they presently  exist. We assume
no obligation to revise or supplement  this opinion  should the present  federal
laws of the United States, or the present laws of Massachusetts or Delaware,  be
changed by legislative  action,  judicial decision,  or otherwise.  Further,  we
express no opinion with respect to any government  authority,  license or permit
that may be required in  connection  with the operation of SRC after the date of
this opinion.  We express no opinion as to the  applicability  or effect of laws
relating to choice-of-law or conflict-of-law matters.

         We express no opinion  as to any  matter  other than as  expressly  set
forth above,  and no other opinion is intended to be implied nor may be inferred
herefrom.  The opinions  expressed above are given as of the date hereof, and we
undertake no obligation  hereby and disclaim any obligation to advise you of any
change after the date hereof pertaining to any matter referred to herein.

         This  opinion is  furnished  for the  benefit of and may be relied upon
only by the Buyer.  This  opinion may not be relied upon by any other  entity or
Person without, in each instance, obtaining our prior written consent.

                                                       Very truly yours,




                                                       MINTZ LEVIN COHN, FERRIS,
                                                       GLOVSKY and POPEO, P.C.

Cooley Godward LLP             ATTORNEYS AT LAW




June 9, 1999


                                                               Barbara L. Borden
                                                                    619 550-6064
                                                               [email protected]

To the Stockholders of
System Resources Corporation listed on
the Attached Schedule A

Dear Ladies and Gentlemen:

We have  acted as counsel  for The Titan  Corporation,  a  Delaware  corporation
("Titan"),  and  Titan  Technologies  and  Information  Systems  Corporation,  a
Delaware  corporation  ("Titan  Technologies")  and  wholly-owned  subsidiary of
Titan, in connection  with the purchase of all the outstanding  shares of System
Resources  Corporation,  a Delaware  corporation  ("SRC"),  pursuant  to a Stock
Purchase Agreement dated June 9, 1999, by and among Titan Technologies,  SRC and
the  stockholders  of SRC (the  "Purchase  Agreement").  We are  rendering  this
opinion pursuant to Section 3.2(g) of the Purchase Agreement.  Capitalized terms
used but not defined  herein have the  respective  meanings given to them in the
Purchase Agreement or Guarantee (as defined below).

In  connection  with  this  opinion,  we  have  examined  and  relied  upon  the
representations  and  warranties  as to factual  matters  contained  in and made
pursuant  to the  Purchase  Agreement,  the  Guarantee  dated  June 9, 1999 (the
"Guarantee") by Titan, as guarantor, in favor of the former stockholders of SRC,
as  secured   parties,   the   Noncompetition   Agreement  by  and  among  Titan
Technologies,  SRC and the stockholders of SRC (the "Noncompetition  Agreement")
and the Promissory  Notes dated June 9, 1999, in the aggregate  principal amount
of $2,000,000 issued by Titan  Technologies  pursuant to the Purchase  Agreement
(the "Notes") (the Purchase  Agreement,  Noncompetition  Agreement and Notes are
collectively  referred to herein as the  "Agreements"),  and originals or copies
certified  to  our  satisfaction  of  such  records,  documents,   certificates,
opinions,  memoranda and other  instruments  as in our judgment are necessary or
appropriate to enable us to render the opinion expressed below.

In rendering this opinion, we have assumed:  the genuineness and authenticity of
all  signatures  on  original  documents;  the  authenticity  of  all  documents
submitted to us as  originals;  the  conformity  to  originals of all  documents
submitted  to us as copies;  the  accuracy,  completeness  and  authenticity  of
certificates  of public  officials;  and the due  authorization,  execution  and
delivery of all documents (except the due authorization,  execution and delivery
by Titan  Technologies  of the Agreements  and by Titan of the Guarantee)  where
authorization,  execution and delivery are prerequisites to the effectiveness of
such  documents.  We have  also  assumed:  that all  individuals  executing  and
delivering  documents  had the  legal  capacity  to  execute  and  deliver  such
documents;  that Titan and Titan  Technologies  have received all documents that
they were to receive under the Agreements;  that the Agreements are binding upon
the parties thereto other than Titan Technologies; that the Guarantee is binding
upon the parties thereto other than Titan; that the Creditors are relying on the
Guarantee and would not grant credit under the related  Promissory  Notes in the
absence  of the  Guarantee;  that  Titan and Titan  Technologies  have filed any
required state  franchise or income tax returns and have paid any required state
franchise  or income  taxes;  and that  there  are no  extrinsic  agreements  or
understandings  among any of the parties to the Agreements  that would modify or
interpret the terms of the Agreements or the respective rights or obligations of
the parties thereunder.

Our  opinion  in  paragraph  3,  below,   is  subject  to  and  limited  by  the
qualification that, if Titan is deemed to be liable as a principal on the Notes,
it is likely that it will also be entitled to the rights and defenses  otherwise
available to a principal with respect to the Notes.

We express no opinion with respect to the effect of (a) any  modification  to or
amendment of the Guarantied  Indebtedness of Titan Technologies  without Titan's
consent which  materially  increases such  Guarantied  Indebtedness;  or (b) any
election of remedies by the  Creditors  following  the failure to timely pay the
Guarantied  Indebtedness  or any other action by the Creditors  that  materially
prejudices  Titan,  if, in any such  instance,  such  election or action  occurs
without  notice to Titan and without  granting  Titan an opportunity to cure any
default by Titan Technologies.

With regard to our opinion in  paragraph  4 below with  respect to any  material
agreement  known to us, we have relied  solely upon (i) inquiries of officers of
Titan Technologies,  (ii) a list supplied to us by Titan Technologies, a copy of
which is  attached  hereto as Exhibit A, of material  agreements  to which Titan
Technologies  is a party,  or by which it is bound, as the date hereof and (iii)
an examination of the items of the aforementioned  list; we have made no further
investigations.

We have assumed that the Creditors will act in accordance  with  applicable law,
and, to the extent  required by such  applicable  law,  the  Creditors  will act
fairly,  in good faith and in a  commercially  reasonable  and prudent manner in
exercising its rights.

We express no  opinion  regarding  any law or  governmental  rule or  regulation
regarding maximum allowable interest rates.

Our opinion is  expressed  only with  respect to the federal  laws of the United
States  of  America  and the laws of the  State of  California  and the  General
Corporation  Law of the State of  Delaware.  We express no opinion as to whether
the laws of any particular jurisdiction apply, and no opinion to the extent that
the laws of any jurisdiction other than those identified above are applicable to
the  subject  matter  hereof.  We  are  not  rendering  any  opinion:  (i) as to
compliance  with, or the effects upon  obligations  arising under the Agreements
of,  any  law,  rule or  regulation  relating  to  securities  or to the sale or
issuance  thereof;  (ii) as to compliance  with, or the effects upon obligations
arising  under the  Agreements  of,  any law,  rule or  regulation  relating  to
antitrust, trade regulation or unfair competition;  or (iii) except as expressly
set forth below, as to the  enforceability of any of the agreements  attached as
exhibits to the Purchase Agreement.

On the  basis of the  foregoing,  in  reliance  thereon  and with the  foregoing
qualifications, we are of the opinion that:

     1. Each of Titan and Titan Technologies is a corporation duly incorporated,
validly existing and in good standing under the laws of the State of Delaware.

     2. Titan  Technologies  has the requisite  corporate power and authority to
perform its obligations under the Agreements.  Titan has the requisite corporate
power  and  authority  to  perform  its  obligations  under the  Guarantee.  The
execution, delivery and performance of the Agreements by Titan Technologies have
been duly authorized by all necessary action on the part of Titan  Technologies'
board of directors. The execution,  delivery and performance of the Guarantee by
Titan have been duly  authorized by all necessary  action on the part of Titan's
board of  directors.  The  Agreements  have been duly and validly  executed  and
delivered  by  Titan  Technologies.  The  Guarantee  has been  duly and  validly
executed and delivered by Titan.

     3. The Agreements  constitute the legal,  valid and binding  obligations of
Titan  Technologies,  enforceable  against Titan Technologies in accordance with
their  terms,  except as may be limited by, and  subject to (a)  general  equity
principles and to limitations on the availability of equitable relief, including
specific  performance;  (b) the  effect of  applicable  bankruptcy,  insolvency,
reorganization,  arrangement, moratorium, receivership, suretyship, dissolution,
moratorium,  receivership  or other  similar laws  relating to or affecting  the
rights of creditors generally,  including but not limited to those affecting the
rights of secured  creditors;  (c)  limitations  on a borrower's or  guarantor's
ability to waive rights or benefits  given by statute or  otherwise,  including,
without  limitation,  rights and  benefits  belonging  to the  primary  obligor,
whether or not such primary  obligor has itself  waived such rights or benefits;
(d)  limitations  on the  right of a lender  to impose  added  charges  for late
payments or defaults by the borrower,  where it is determined  that such charges
bear no reasonable  relation to the damage suffered by the lender as a result of
such late payments or defaults or where the  requirements  of  California  Civil
Code Section  2954.5 are not met; (e)  limitations  on the  enforceability  of a
clause  prohibiting  or  restricting  prepayment  of  indebtedness  or  imposing
prepayment charges;  (f) the effect of California Civil Code Section 1717 on the
recovery of attorneys' fees in contract actions;  (g) limitations on the ability
of a  secured  creditor  to enter,  take  possession  of, or deal as owner  with
respect  to the  collateral  without  judicial  authorization;  (h)  limitations
imposed by California  law on the  appointment  of receivers;  (i) the effect of
California  Civil  Code  Section  3433;  (j)  fraudulent  conveyance  laws;  (k)
limitations   created  by  or  arising   under   statute  or  case  law  on  the
enforceability  of certain covenants and agreements where (1) the breach of such
covenants  or  provisions  imposes  restrictions  or  burdens  upon the  debtor,
including the  acceleration of indebtedness due under debt  instruments,  and it
cannot be demonstrated  that the enforcement of such  restrictions or burdens is
reasonably  necessary for the  protection of the creditor or (2) the  creditor's
enforcement  of such  covenants  or  provisions  under the  circumstances  would
violate the  creditor's  implied  covenant of good faith and fair  dealing;  (l)
limitations  imposed by public policy on  indemnification;  (m) applicable  laws
limiting rights to indemnity;  (n) defenses  available to guarantors  generally;
(o) limitations on corporate  distributions  imposed by Sections 500 et. seq. of
the  General  Corporation  Law of the  State of  California;  and (o) any  other
limitations  which,  in the  event of a  default  by Titan  Technologies  in its
obligations  under the Agreements or a default by Titan in its obligations under
the  Guarantee,  would act as a  limitation  on the  rights of  lender,  each in
accordance  with  California law  ("Enforceability  Exceptions").  The Guarantee
constitutes  the legal,  valid and  binding  obligations  of Titan,  enforceable
against  Titan in  accordance  with its terms,  except as may be limited by, and
subject to the Enforceability Exceptions.

     4.  The  execution  and  delivery  of  the  Purchase   Agreement  by  Titan
Technologies and the consummation of the  transactions  contemplated  thereby do
not violate any provision of Titan Technologies' Certificate of Incorporation or
its Bylaws,  do not  constitute a default  under the  provisions of any material
agreement  known to us to which Titan  Technologies is a party or by which Titan
Technologies  is bound and, do not violate or  contravene  (a) any  governmental
statute, rule or regulation applicable to Titan Technologies,  or (b) any order,
writ,  judgment,  injunction,  decree,  determination  or award  which  has been
entered against Titan  Technologies  and of which we are aware, the violation or
contravention  of which  would have a  material  adverse  effect on the  assets,
financial  condition  or  operations  (a  "Material  Adverse  Effect")  of Titan
Technologies.

     5. To our  knowledge,  there  is no  action,  proceeding  or  investigation
pending or overtly  threatened  against Titan  Technologies  or Titan before any
court or  administrative  agency that  questions  the  validity of the  Purchase
Agreement or the Guarantee or that might result,  either  individually or in the
aggregate, in any Material Adverse Effect on Titan Technologies and Titan, taken
as a whole.

     6. All  consents,  approvals,  authorizations  or orders of,  and  filings,
registrations and qualifications with any regulatory or governmental body in the
United States required for the  consummation by Titan  Technologies and Titan of
the transactions contemplated by the Agreements have been made or obtained.

This  opinion  letter and the  opinions  expressed  herein are intended for your
benefit  and are not to be made  available  to or be  relied  upon by any  other
person, firm or entity without our prior written consent.

Very truly yours,

COOLEY GODWARD LLP

3.       CONFIDENTIAL INFORMATION.

                  Seller   acknowledges   and  agrees   that  all   Confidential
Information  known or  obtained  by  Seller,  whether  before  or after the date
hereof,  is the property of the Company.  Therefore,  Seller  agrees that Seller
will not, at any time,  disclose to any unauthorized  Persons or use for his own
account or for the  benefit  of any third  party any  Confidential  Information,
whether Seller has such information in Seller's memory or embodied in writing or
other physical form,  without Buyer's written consent,  unless and to the extent
that the Confidential Information is or becomes generally known to and available
for use by the public  other than as a result of Seller's  fault or the fault of
any other  Person  bound by a duty of  confidentiality  to Buyer or the Company.
Seller  agrees to deliver to Buyer at the time of execution  of this  Agreement,
and at any other time Buyer may request, all documents, memoranda, notes, plans,
records,  reports,  and other  documentation,  models,  components,  devices, or
computer  software,  whether embodied in a disk or in other form (and all copies
of all of the foregoing), relating to the businesses,  operations, or affairs of
the Company and any other Confidential  Information that Seller may then possess
or have under Seller's control. Notwithstanding the foregoing, Seller may retain
copies of financial  information  necessary for the purpose of filing income tax
returns or substantiating prior income tax returns filed on behalf of Seller.

4.       NONCOMPETITION.

                  As an  inducement  for Buyer to enter into the Stock  Purchase
Agreement and as additional  consideration  for the  consideration to be paid to
Seller under the Stock Purchase Agreement, Seller agrees that:

                  (a) For a period of two years after the Closing:

                          (i) Seller will not, directly or indirectly, engage or
invest in,  own,  manage,  operate,  finance,  control,  or  participate  in the
ownership,  management,  operation,  financing  or control of, be  employed  by,
associated  with,  or in any manner  connected  with,  lend Seller's name or any
similar name to, lend Seller's  credit to, or render  services or advice to, any
business  whose  activities  directly  compete  in  whole  or in part  with  the
activities of the Company in the  government  sector,  whether  federal,  state,
municipal or otherwise,  or with existing commercial  customers by providing the
services historically provided by the Company to such customers,  as of the date
of this Agreement,  anywhere within the United States;  provided,  however, that
Seller may purchase or  otherwise  acquire up to (but not more than) one percent
of  any  class  of  securities  of  any   enterprise   (but  without   otherwise
participating  in the  activities of such  enterprise)  if such  securities  are
listed on any national or regional  securities  exchange or have been registered
under Section 12(g) of the Securities  Exchange Act of 1934.  Seller agrees that
this covenant is reasonable with respect to its duration, geographical area, and
scope.

                          (ii) Seller will not,  directly or indirectly,  either
for himself or any other Person, (A) induce or attempt to induce any employee of
the Company to leave the employ of the Company,  (B) in any way  interfere  with
the  relationship  between  the Company and any  employee  of the  Company,  (C)
employ,  or  otherwise  engage  as  an  employee,   independent  contractor,  or
otherwise,  any employee of the Company who is employed by Buyer, Buyer's Parent
or the  Company at the time of contact  by Seller for such  employment  or other
engagement, or (D) induce or attempt to induce any customer, supplier, licensee,
or business relation of the Company to cease doing business with the Company, or
in any way  interfere  with the  relationship  between any  customer,  supplier,
licensee, or business relation of the Company.

                          (iii) Seller will not, directly or indirectly,  either
for himself or any other  Person,  solicit the  business of any Person  known to
Seller to be a  customer  of the  Company  for the  purpose of  engaging  in any
business  with respect to any program in which the Company has  contracts or has
submitted  bids as of the  date  of this  Agreement,  and  any  new  defense  or
government programs that require the same or similar services as are provided by
the Company on the date of this Agreement, anywhere in the United States whether
or not Seller had personal contact with such Person;

                  (b) In the event of a breach by  Seller  of any  covenant  set
forth in Subsection  4(a) of this  Agreement,  the term of such covenant will be
extended by the period of the duration of such breach;

                  (c) Seller will,  for a period of two years after the Closing,
within ten days after accepting any employment,  advise Buyer of the identity of
any  employer of Seller.  Buyer or the  Company may serve  notice upon each such
employer  that Seller is bound by this  Agreement and furnish each such employer
with a copy of this Agreement or relevant portions thereof.

5.       REMEDIES.

                  If Seller  breaches the covenants set forth in Sections 3 or 4
of this  Agreement,  Buyer and the Company  will be  entitled  to the  following
remedies:

                  (a) Damages from Seller; and

                  (b) In addition  to its right to damages and any other  rights
it may have,  to obtain  injunctive  or other  equitable  relief to restrain any
breach or threatened breach or otherwise to specifically  enforce the provisions
of Sections 3 and 4 of this Agreement,  it being agreed that money damages alone
would be  inadequate  to  compensate  the Buyer and the  Company and would be an
inadequate remedy for such breach.

                  (c) The rights and  remedies of the parties to this  Agreement
are cumulative and not alternative.

6.       SUCCESSORS AND ASSIGNS.

                  This  Agreement  will be binding  upon Buyer,  the Company and
Seller  and will  inure  to the  benefit  of Buyer  and the  Company  and  their
affiliates,  successors and assigns and Seller and Seller's  assigns,  heirs and
legal representatives.

7.       WAIVER.

                  The rights and remedies of the parties to this  Agreement  are
cumulative and not  alternative.  Neither the failure nor any delay by any party
in exercising any right,  power,  or privilege under this Agreement will operate
as a waiver of such  right,  power,  or  privilege,  and no  single  or  partial
exercise of any such right,  power,  or  privilege  will  preclude  any other or
further exercise of such right, power, or privilege or the exercise of any other
right,  power, or privilege.  To the maximum extent permitted by applicable law,
(a) no claim or right  arising out of this  Agreement  can be  discharged by one
party,  in whole or in part, by a waiver or  renunciation  of the claim or right
unless in writing signed by the other party;  (b) no waiver that may be given by
a party  will be  applicable  except in the  specific  instance  for which it is
given; and (c) no notice to or demand on one party will be deemed to be a waiver
of any  obligation of such party or of the right of the party giving such notice
or demand to take further  action  without  notice or demand as provided in this
Agreement.

8.       GOVERNING LAW.

                  This  Agreement  will be  governed by the laws of the State of
California without regard to conflicts of laws principles.

9.       JURISDICTION; SERVICE OF PROCESS.

                  Any action or proceeding  seeking to enforce any provision of,
or based on any right arising out of, this Agreement may be brought  against any
of the  parties in the courts of the State of  California,  County of San Diego,
or, if it has or can acquire  jurisdiction,  in the United States District Court
for the Southern District of California, and each of the parties consents to the
jurisdiction  of such courts (and of the  appropriate  appellate  courts) in any
such action or proceeding  and waives any  objection to venue laid  therein.  In
addition,  Buyer may, at its option,  bring any action or proceeding  seeking to
enforce any provision  of, or based on any right arising out of, this  Agreement
against Seller in the courts of the Commonwealth of Massachusetts, or, if it has
or can  acquire  jurisdiction,  in the  United  States  District  Court  for the
Commonwealth of Massachusetts, and Seller hereby consents to the jurisdiction of
such  courts  (and of the  appropriate  appellate  courts) in any such action or
proceeding and waives any objection to venue laid therein. Process in any action
or proceeding  referred to in the preceding  sentence may be served on any party
anywhere in the world.

10.      SEVERABILITY.

                  Whenever  possible each  provision and term of this  Agreement
will be  interpreted  in a manner to be effective and valid but if any provision
or term of this  Agreement  is held to be  prohibited  by or invalid,  then such
provision or term will be ineffective  only to the extent of such prohibition or
invalidity,  without  invalidating  or  affecting in any manner  whatsoever  the
remainder of such provision or term or the remaining provisions or terms of this
Agreement.  If any of the covenants set forth in Section 4 of this Agreement are
held to be  unreasonable,  arbitrary,  or against public policy,  such covenants
will be considered  divisible with respect to scope,  time, and geographic area,
and in such lesser scope,  time and geographic area, will be effective,  binding
and enforceable against Seller.

11.      COUNTERPARTS.

                  This  Agreement  may be executed in one or more  counterparts,
each of which will be deemed to be an original copy of this Agreement and all of
which,  when  taken  together,  will be  deemed to  constitute  one and the same
agreement.

12.      SECTION HEADINGS, CONSTRUCTION.

                  The  headings of Sections in this  Agreement  are provided for
convenience  only and will not affect its  construction or  interpretation.  All

                          LEASE MODIFICATION AGREEMENT


         THIS LEASE MODIFICATION AGREEMENT  ("Amendment") dated June ____, 1999,
by and between MNM SERVICES,  Inc., a Massachusetts  corporation  ("Lessor") and
SYSTEM RESOURCES CORPORATION,  a Delaware corporation ("Lessee")  (collectively,
the "Parties").

                                   WITNESSETH

         WHEREAS,  the parties entered into a Lease Agreement dated May 31, 1996
(the "Lease") for those certain premises  designated in said lease consisting of
Unit 409 at 1805  Crystal  Drive  located in  Arlington,  Virginia  (hereinafter
referred to as the "Lease");

         WHEREAS,  the  Parties  acknowledge  that Lessee will become the wholly
owned  subsidiary of Titan  Technologies  and  Information  Systems  Corporation
("Buyer") in connection  with a Stock  Purchase  Agreement  dated June ___, 1999
(the "Agreement") by and among Buyer, Lessee, and the stockholders of Lessee, as
defined in the Agreement; and

         WHEREAS,  Lessor  and  Lessee  mutually  intend and desire to amend the
Lease on and subject to the terms and conditions hereinafter set forth.

         NOW  THEREFORE,  in  consideration  of the  premises and other good and
valuable  consideration,  the receipt and legal  sufficiency  of which is hereby
acknowledged, Lessor and Lessee hereby agree as follows:

1. The following new Section 16 of the Lease is hereby added to the Lease:

                  16.      Assignment.

                  The Lessee shall not assign or sublet the whole or any part of
                  the leased premises  without  Lessor's prior written  consent,
                  which consent shall not be unreasonably  withheld.  Lessor may
                  withhold  its  consent  if in its  reasonable  discretion  the
                  proposed  assignee  is not  creditworthy  and  Lessor is being
                  asked to release the Lessee from all further  liability  under
                  the  Lease.  Lessee  shall  remain  liable to  Lessor  for the
                  payment of rent and for the full  performance of the covenants
                  and  conditions  of this Lease  regardless in the event of any
                  subletting  of the premises by Lessee  unless Lessor agrees in
                  writing  to  release  Lessee in order to  trigger a release of
                  funds  under  Section 2 of the  Indemnity  Side Letter of even
                  date attached  hereto as Exhibit A ("Exhibit  A").  Lessor may
                  not condition its consent to any assignment or sublease on the
                  payment of any fees or upon any modifications to the Lease.

2. The following new Section 17 is hereby added to the Lease:

                  17.      Termination Option.

                           Lessor shall have the right to  terminate  this Lease
                  by giving  Lessee six (6) months  written  notice to Lessee of
                  Lessor's  intent to terminate the Lease  ("Lessor  Termination
                  Option").  Notwithstanding  the  foregoing,  if the Lessee has
                  sublet  any  portion  of the  premises,  or has  assigned  its
                  interest in the Lease in each instance in accordance  with the
                  provisions  of Section 1 of this  Amendment,  the Lessor shall
                  not have the right to exercise the Lessor  Termination  Option
                  as to any  assigned  or sublet  premises.  Lessor  retains the
                  right to exercise the Lessor  Termination  Option prior to the
                  approval or acceptance of any proposed sublease or assignment.

                           The  Lessee  shall have the right to  terminate  this
                  Lease by giving  four (4) months  written  notice to Lessor of
                  Lessee's  intent to terminate the Lease  ("Lessee  Termination
                  Option");  provided, however, that Lessee shall have the right
                  to exercise  the Lessee  Termination  Option only if either of
                  the conditions set forth in the first two sentences of Section
                  4(c) of Exhibit A occurs.

3. As amended hereby,  the Lease is ratified and confirmed and declared to be in
full force and effect.  Unless otherwise defined herein, all defined terms shall
have the meaning set forth in the Agreement and the Lease.

         THIS LEASE MODIFICATION AGREEMENT  ("Amendment") dated June ____, 1999,
by and between MNM SERVICES,  Inc., a Massachusetts  corporation  ("Lessor") and
SYSTEM RESOURCES CORPORATION,  a Delaware corporation ("Lessee")  (collectively,
the "Parties").

                                   WITNESSETH

         WHEREAS, the parties entered into a Lease Agreement dated July 16, 1996
(the "Lease") for those certain premises  designated in said lease consisting of
Unit 317C at the Hilton  Head  Island  Beach & Tennis  Resort  located in Hilton
Head, South Carolina (hereinafter referred to as the "Lease");

         WHEREAS,  the  Parties  acknowledge  that Lessee will become the wholly
owned  subsidiary of Titan  Technologies  and  Information  Systems  Corporation
("Buyer") in connection  with a Stock  Purchase  Agreement  dated June ___, 1999
(the "Agreement") by and among Buyer, Lessee, and the stockholders of Lessee, as
defined in the Agreement; and

         WHEREAS,  Lessor  and  Lessee  mutually  intend and desire to amend the
Lease on and subject to the terms and conditions hereinafter set forth.

         NOW  THEREFORE,  in  consideration  of the  premises and other good and
valuable  consideration,  the receipt and legal  sufficiency  of which is hereby
acknowledged, Lessor and Lessee hereby agree as follows:

1. The following new Section 16 of the Lease is hereby added to the Lease:

                  16.      Assignment.

                  The Lessee shall not assign or sublet the whole or any part of
                  the leased premises  without  Lessor's prior written  consent,
                  which consent shall not be unreasonably  withheld.  Lessor may
                  withhold  its  consent  if in its  reasonable  discretion  the
                  proposed  assignee  is not  creditworthy  and  Lessor is being
                  asked to release the Lessee from all further  liability  under
                  the  Lease.  Lessee  shall  remain  liable to  Lessor  for the
                  payment of rent and for the full  performance of the covenants
                  and  conditions  of this Lease  regardless in the event of any
                  subletting  of the premises by Lessee  unless Lessor agrees in
                  writing  to  release  Lessee in order to  trigger a release of
                  funds  under  Section 2 of the  Indemnity  Side Letter of even
                  date attached  hereto as Exhibit A ("Exhibit  A").  Lessor may
                  not condition its consent to any assignment or sublease on the
                  payment of any fees or upon any modifications to the Lease.

2. The following new Section 17 is hereby added to the Lease:

                  17.      Termination Option.

                           Lessor shall have the right to  terminate  this Lease
                  by giving  Lessee six (6) months  written  notice to Lessee of
                  Lessor's  intent to terminate the Lease  ("Lessor  Termination
                  Option").  Notwithstanding  the  foregoing,  if the Lessee has
                  sublet  any  portion  of the  premises,  or has  assigned  its
                  interest in the Lease in each instance in accordance  with the
                  provisions  of Section 1 of this  Amendment,  the Lessor shall
                  not have the right to exercise the Lessor  Termination  Option
                  as to any  assigned  or sublet  premises.  Lessor  retains the
                  right to exercise the Lessor  Termination  Option prior to the
                  approval or acceptance of any proposed sublease or assignment.

                           The  Lessee  shall have the right to  terminate  this
                  Lease by giving  four (4) months  written  notice to Lessor of
                  Lessee's  intent to terminate the Lease  ("Lessee  Termination
                  Option");  provided, however, that Lessee shall have the right
                  to exercise  the Lessee  Termination  Option only if either of
                  the conditions set forth in the first two sentences of Section
                  4(c) of Exhibit A occurs.

                                      NO. 2


         THIS LEASE MODIFICATION AGREEMENT NO. 2 ("Second Amendment") dated June
____,  1999,  by and between MNM  SERVICES,  INC., a  Massachusetts  corporation
("Lessor") and SYSTEM RESOURCES  CORPORATION,  a Delaware corporation ("Lessee")
(collectively, the "Parties").

                                   WITNESSETH

         WHEREAS,  the parties  entered into a Lease  Agreement dated October 1,
1996  (the  "Lease")  for  those  certain  premises  designated  in  said  lease
consisting  of 4,182  square  feet on the first floor  within 128  Wheeler  Road
located in Burlington, Massachusetts (hereinafter referred to as the "Lease");

         WHEREAS,  the  Parties  acknowledge  that Lessee will become the wholly
owned  subsidiary of Titan  Technologies  and  Information  Systems  Corporation
("Buyer") in connection  with a Stock  Purchase  Agreement  dated June ___, 1999
(the "Agreement") by and among Buyer, Lessee, and the stockholders of Lessee, as
defined in the Agreement; and

         WHEREAS,  Lessor  and  Lessee  mutually  intend and desire to amend the
Lease on and subject to the terms and conditions hereinafter set forth.

         NOW  THEREFORE,  in  consideration  of the  premises and other good and
valuable  consideration,  the receipt and legal  sufficiency  of which is hereby
acknowledged, Lessor and Lessee hereby agree as follows:

     1. Section 13 of the Lease ("Assignment"), shall be deleted in its entirety
and replaced with the following language:

                  The Lessee shall not assign or sublet the whole or any part of
                  the leased premises  without  Lessor's prior written  consent,
                  which consent shall not be unreasonably  withheld.  Lessor may
                  withhold  its  consent  if in its  reasonable  discretion  the
                  proposed  assignee  is not  creditworthy  and  Lessor is being
                  asked to release the Lessee from all further  liability  under
                  the  Lease.  Lessee  shall  remain  liable to  Lessor  for the
                  payment of rent and for the full  performance of the covenants
                  and  conditions  of this Lease  regardless in the event of any
                  subletting  of the premises by Lessee  unless Lessor agrees in
                  writing  to  release  Lessee in order to  trigger a release of
                  funds  under  Section 2 of the  Indemnity  Side Letter of even
                  date attached  hereto as Exhibit A ("Exhibit  A").  Lessor may
                  not condition its consent to any assignment or sublease on the
                  payment of any fees or upon any modifications to the Lease.

     2. The following new Section 35 is hereby added to the Lease and Section 35
is renumbered as Section 36:

                  35.      Termination Option.

                           Lessor shall have the right to  terminate  this Lease
                  by giving  Lessee six (6) months  written  notice to Lessee of
                  Lessor's  intent to terminate the Lease  ("Lessor  Termination
                  Option").  Notwithstanding  the  foregoing,  if the Lessee has
                  sublet  any  portion  of the  premises,  or has  assigned  its
                  interest in the Lease in each instance in accordance  with the
                  provisions of Section 1 of this Second  Amendment,  the Lessor
                  shall not have the right to  exercise  the Lessor  Termination
                  Option as to any assigned or sublet  premises.  Lessor retains
                  the right to exercise the Lessor  Termination  Option prior to
                  the  approval  or  acceptance  of  any  proposed  sublease  or
                  assignment.

                           The  Lessee  shall have the right to  terminate  this
                  Lease by giving  four (4) months  written  notice to Lessor of
                  Lessee's  intent to terminate the Lease  ("Lessee  Termination
                  Option");  provided, however, that Lessee shall have the right
                  to exercise  the Lessee  Termination  Option only if either of
                  the conditions set forth in the first two sentences of Section
                  4(c) of Exhibit A occurs.

     3. As amended  hereby,  the Lease is ratified and confirmed and declared to
be in full force and effect.  Unless otherwise defined herein, all defined terms
shall have the meaning set forth in the Agreement and the Lease.

         THIS LEASE MODIFICATION AGREEMENT NO. 2 ("Second Amendment") dated June
____,  1999,  by and between MNM  SERVICES,  INC., a  Massachusetts  corporation
("Lessor") and SYSTEM RESOURCES  CORPORATION,  a Delaware corporation ("Lessee")
(collectively, the "Parties").

                                   WITNESSETH

         WHEREAS,  the parties  entered into a Lease  Agreement dated October 1,
1996  (the  "Lease")  for  those  certain  premises  designated  in  said  lease
consisting  of 5,286  square  feet on the first floor  within 128  Wheeler  Road
located in Burlington, Massachusetts (hereinafter referred to as the "Lease");

         WHEREAS,  the  Parties  acknowledge  that Lessee will become the wholly
owned  subsidiary of Titan  Technologies  and  Information  Systems  Corporation
("Buyer") in connection  with a Stock  Purchase  Agreement  dated June ___, 1999
(the "Agreement") by and among Buyer, Lessee, and the stockholders of Lessee, as
defined in the Agreement; and

         WHEREAS,  Lessor  and  Lessee  mutually  intend and desire to amend the
Lease on and subject to the terms and conditions hereinafter set forth.

         NOW  THEREFORE,  in  consideration  of the  premises and other good and
valuable  consideration,  the receipt and legal  sufficiency  of which is hereby
acknowledged, Lessor and Lessee hereby agree as follows:

     1. Section 13 of the Lease ("Assignment"), shall be deleted in its entirety
and replaced with the following language:

                  The Lessee shall not assign or sublet the whole or any part of
                  the leased premises  without  Lessor's prior written  consent,
                  which consent shall not be unreasonably  withheld.  Lessor may
                  withhold  its  consent  if in its  reasonable  discretion  the
                  proposed  assignee  is not  creditworthy  and  Lessor is being
                  asked to release the Lessee from all further  liability  under
                  the  Lease.  Lessee  shall  remain  liable to  Lessor  for the
                  payment of rent and for the full  performance of the covenants
                  and  conditions  of this Lease  regardless in the event of any
                  subletting  of the premises by Lessee  unless Lessor agrees in
                  writing  to  release  Lessee in order to  trigger a release of
                  funds  under  Section 2 of the  Indemnity  Side Letter of even
                  date attached  hereto as Exhibit A ("Exhibit  A").  Lessor may
                  not condition its consent to any assignment or sublease on the
                  payment of any fees or upon any modifications to the Lease.

     2. The following new Section 35 is hereby added to the Lease and Section 35
is renumbered as Section 36:

                  35.      Termination Option.

                           Lessor shall have the right to  terminate  this Lease
                  by giving  Lessee six (6) months  written  notice to Lessee of
                  Lessor's  intent to terminate the Lease  ("Lessor  Termination
                  Option").  Notwithstanding  the  foregoing,  if the Lessee has
                  sublet  any  portion  of the  premises,  or has  assigned  its
                  interest in the Lease in each instance in accordance  with the
                  provisions of Section 1 of this Second  Amendment,  the Lessor
                  shall not have the right to  exercise  the Lessor  Termination
                  Option as to any assigned or sublet  premises.  Lessor retains
                  the right to exercise the Lessor  Termination  Option prior to
                  the  approval  or  acceptance  of  any  proposed  sublease  or
                  assignment.

                           The  Lessee  shall have the right to  terminate  this
                  Lease by giving  four (4) months  written  notice to Lessor of
                  Lessee's  intent to terminate the Lease  ("Lessee  Termination
                  Option");  provided, however, that Lessee shall have the right

                                   WITNESSETH

         WHEREAS,  the parties  entered into a Lease  Agreement dated October 1,
1996  (the  "Lease")  for  those  certain  premises  designated  in  said  lease
consisting  of 12,663  square feet on the second  floor  within 128 Wheeler Road
located in Burlington, Massachusetts (hereinafter referred to as the "Lease");

         WHEREAS,  the  Parties  acknowledge  that Lessee will become the wholly

("Buyer") in connection  with a Stock  Purchase  Agreement  dated June ___, 1999

         NOW  THEREFORE,  in  consideration  of the  premises and other good and
valuable  consideration,  the receipt and legal  sufficiency  of which is hereby
acknowledged, Lessor and Lessee hereby agree as follows:

     1. Section 13 of the Lease ("Assignment"), shall be deleted in its entirety
and replaced with the following language:

                  The Lessee shall not assign or sublet the whole or any part of
                  the leased premises  without  Lessor's prior written  consent,
                  which consent shall not be unreasonably  withheld.  Lessor may
                  withhold  its  consent  if in its  reasonable  discretion  the

                  asked to release the Lessee from all further  liability  under
                  the  Lease.  Lessee  shall  remain  liable to  Lessor  for the
                  payment of rent and for the full  performance of the covenants
                  and  conditions  of this Lease  regardless in the event of any
                  subletting  of the premises by Lessee  unless Lessor agrees in
                  writing  to  release  Lessee in order to  trigger a release of
                  funds  under  Section 2 of the  Indemnity  Side Letter of even

                  not condition its consent to any assignment or sublease on the
                  payment of any fees or upon any modifications to the Lease.

     2. The following new Section 35 is hereby added to the Lease and Section 35
is renumbered Section 36:

                  35.      Termination Option.

                           Lessor shall have the right to  terminate  this Lease
                  by giving  Lessee six (6) months  written  notice to Lessee of
                  Lessor's  intent to terminate the Lease  ("Lessor  Termination
                  Option").  Notwithstanding  the  foregoing,  if the Lessee has
                  sublet  any  portion  of the  premises,  or has  assigned  its
                  interest in the Lease in each instance in accordance  with the
                  provisions of Section 1 of this Second  Amendment,  the Lessor
                  shall not have the right to  exercise  the Lessor  Termination
                  Option as to any assigned or sublet  premises.  Lessor retains
                  the right to exercise the Lessor  Termination  Option prior to
                  the  approval  or  acceptance  of  any  proposed  sublease  or

                           The  Lessee  shall have the right to  terminate  this
                  Lease by giving  four (4) months  written  notice to Lessor of
                  Lessee's  intent to terminate the Lease  ("Lessee  Termination

underscored)  when used in this Agreement,  including its preamble and recitals,
shall, except where the context otherwise requires,  have the following meanings
(such  meanings  to be equally  applicable  to the  singular  and  plural  forms
thereof):

         "Administrative  Agent" is defined in the preamble  and  includes  each
other Person appointed as the successor Administrative Agent pursuant to Section
9.4.

indirectly,  controls,  is  controlled  by or is under common  control with such
Person. "Control" of a Person means the power, directly or indirectly,

         basis)  having  ordinary  voting power for the  election of  directors,
         managing members or general partners (as applicable); or

                  (b) to direct or cause the  direction  of the  management  and
         policies of such Person (whether by contract or otherwise).

         "Agreement"  means, on any date, this Credit Agreement as originally in
effect  on the  Effective  Date and as  thereafter  from  time to time  amended,
supplemented,  amended and restated or otherwise  modified and in effect on such
date.

         "Alternate  Base Rate" means,  on any date and with respect to all Base
Rate  Loans,  a  fluctuating  rate of interest  per annum  (rounded  upward,  if
necessary, to the next highest 1/16 of 1%) equal to the higher of

                  (a)  the Base Rate in effect on such day; and

                  (b) the  Federal  Funds Rate in effect on such day plus 1/2 of
         1%.

Changes in the rate of interest on that portion of any Loans  maintained as Base

not affect the Alternate Base Rate in effect after such change.

         "Applicable  Commitment  Fee  Margin"  means at all  times  during  the
applicable  periods  set forth  below  with  respect  to the fee  payable to the
Lenders pursuant to Section 3.3.1:

percentage set forth below under the column entitled "Applicable  Commitment Fee

         Commitment Fee Margin in respect of the New Acquisition Loan Commitment
         (i) shall be reduced to 0.67% (on a per annum basis) upon  reduction of
         the New  Acquisition  Loan  Commitment to $23,333,000 or less, and (ii)

         Loan  Lender")  will make loans  (relative to such Lender,  its "Term B
         Loans")  to the  Borrower  equal  to such  Lender's  Percentage  of the
         aggregate amount of each Borrowing of the Term B Loans requested by the
         Borrower  to be made on such  day.  No  amounts  paid or  prepaid  with
         respect to Term B Loans may be reborrowed.

                  (c) From time to time on any Business Day  occurring  from and
         after the Effective  Date but prior to the New  Acquisition  Conversion
         Date, each Lender that has a New Acquisition Loan Commitment  (referred
         to as a "New Acquisition Loan Lender",  and together with each Original
         Acquisition  Loan  Lender  and each Term B Loan  Lender,  a "Term  Loan
         Lender") will make loans (relative to such Lender, its "New Acquisition
         Loans")  to the  Borrower  equal  to such  Lender's  Percentage  of the
         aggregate amount of each Borrowing of the New Acquisition Loans

                                      -31-

requested  by the  Borrower to be made on such day.  No amounts  paid or prepaid
with respect to New Acquisition Loans may be reborrowed.

         SECTION  2.1.5.  Lenders Not  Permitted  or Required to Make Loans.  No
Lender shall be  permitted or required to make any Loan if, after giving  effect
thereto, the aggregate outstanding principal amount of:

                  (a)  all Revolving Loans

                           (i) of all Revolving Loan Lenders and the outstanding
                  principal  amount of all Swing Line Loans,  together  with the
                  aggregate amount of all Letter of Credit  Outstandings,  would
                  exceed the then existing Revolving Loan Commitment Amount; or

                           (ii) of such  Revolving  Loan Lender,  together  with
                  such Lender's  Percentage of the aggregate amount of all Swing
                  Line Loans and  Letter of Credit  Outstandings,  would  exceed
                  such Lender's  Percentage of the then existing  Revolving Loan
                  Commitment Amount;

                  (b)  all Term B Loans

                           (i) of all Lenders made on the  Effective  Date would
                  exceed the Term B Loan Commitment Amount; or

                           (ii) of  such  Lender  with a Term B Loan  Commitment
                  made  on  the  Effective   Date  would  exceed  such  Lender's
                  Percentage of the Term B Loan Commitment Amount; or

                  (c)  all New Acquisition Loans

                           (i) of all Lenders made prior to the New  Acquisition
                  Conversion  Date  would  exceed  the  New   Acquisition   Loan
                  Commitment Amount; or

                           (ii)  of  such  Lender  with a New  Acquisition  Loan
                  Commitment made prior to the New  Acquisition  Conversion Date
                  would exceed such Lender's  Percentage of the New  Acquisition
                  Loan Commitment Amount; or

                  (d) (i) all Swing Line Loans  would  exceed the then  existing
         Swing Line Loan Commitment Amount or (ii) unless otherwise agreed to by
         the Swing Line  Lender,  in its sole  discretion,  the sum of all Swing
         Line Loans and  Revolving  Loans made by Scotiabank  plus  Scotiabank's
         Percentage  multiplied  by the  aggregate  amount  of  Letter of Credit
         Outstandings   would  exceed  the  amount   determined  by  multiplying
         Scotiabank's  Percentage by the then existing Revolving Loan Commitment
         Amount.

         SECTION  2.1.6.  Issuer Not  Permitted or Required to Issue  Letters of
Credit.  No Issuer  shall be permitted or required to issue any Letter of Credit
if, after  giving  effect  thereto,  (a) the  aggregate  amount of all Letter of
Credit  Outstandings  would exceed the Letter of Credit Commitment Amount or (b)
the sum of the aggregate  amount of all Letter of Credit  Outstandings  plus the
aggregate  principal  amount of all  Revolving  Loans and Swing  Line Loans then
outstanding would exceed the Revolving Loan Commitment Amount.

         SECTION  2.2.  Reduction  of the  Commitment  Amounts.  The  Commitment
Amounts are subject to reduction from time to time pursuant to this Section 2.2.

         SECTION  2.2.1.  Optional.  The Borrower  may, from time to time on any
Business Day occurring after the Effective Date,  voluntarily  reduce the amount
of the Revolving Loan Commitment  Amount,  the New  Acquisition  Loan Commitment
Amount (on any date before the New Acquisition  Conversion Date), the Swing Line
Loan Commitment Amount or the Letter of Credit Commitment Amount on the Business
Day so specified by the Borrower;  provided,  however,  that all such reductions
shall  require at least one Business  Day's prior  notice to the  Administrative
Agent and be permanent, and any partial reduction of any Commitment Amount shall
be in a minimum  amount of $1,000,000  and in an integral  multiple of $500,000.
Any  reduction  of the  Revolving  Loan  Commitment  Amount  which  reduces  the
Revolving Loan Commitment Amount below the then current amount of the Swing Line
Loan Commitment Amount shall result in an automatic and corresponding  reduction
of the Swing Line Loan  Commitment  Amount to the amount of the  Revolving  Loan
Commitment  Amount,  as so reduced,  without  any further  action on the part of
Scotiabank or otherwise.  Any reduction of the Revolving Loan Commitment  Amount
which reduces the Revolving Loan Commitment Amount below the then current amount
of the Letter of Credit  Commitment  Amount  shall  result in an  automatic  and
corresponding  reduction of the Letter of Credit Commitment Amount to the amount
of the Revolving  Loan  Commitment  Amount,  as so reduced,  without any further
action on the part of Scotiabank or otherwise.

         SECTION 2.2.2.  Mandatory.  (a) On the New Acquisition Conversion Date,
the New Acquisition Loan Commitment  Amount shall  automatically and without the
requirement  of any action on the part of any Person be  permanently  reduced to
zero,  and (b) on the date the  Borrower or any of its  Restricted  Subsidiaries
receives any Net Proceeds and after the expiration of any period  designated for
the purchase of Qualified Assets, if appropriate,  the amounts outstanding under
the Term  Loans,  the New  Acquisition  Conversion  Amount (on and after the New
Acquisition  Conversion  Date) and the Revolving Loan Commitment  Amount (on the
date all Term Loans have been paid in full), shall be reduced by an amount equal
to 100% of Net Proceeds  with respect to Net Proceeds  described in clauses (b),
(c), and (d) of the definition thereof and 50% of such Net Proceeds with respect
to the Net Proceeds described in clause (a) of the definition thereof; provided,
however,  that the Revolving Loan Commitment Amount shall only be reduced by the
Net Proceeds described in clause (b) of the definition thereof.

         SECTION 2.3. Borrowing Procedures.  Loans (other than Swing Line Loans)
shall be made by the Lenders in accordance  with Section  2.3.1,  and Swing Line
Loans shall be made by Scotiabank in accordance with Section 2.3.2.

                                      -33-

         SECTION  2.3.1.  Borrowing  Procedure.  In the case of other than Swing
Line Loans, by delivering a Borrowing Request to the Administrative  Agent on or
before 12:00 noon,  New York time, on a Business Day, the Borrower may from time
to time irrevocably  request,  on not less than one Business Day's notice in the
case of Base Rate Loans, or three Business Days' notice in the case of LIBO Rate
Loans,  and in either  case not more than five  Business  Days'  notice,  that a
Borrowing  be made,  in the case of LIBO  Rate  Loans,  in a  minimum  amount of
$500,000 and an integral  multiple of $500,000,  in the case of Base Rate Loans,
in a minimum  amount of  $500,000  and an integral  multiple of $100,000  or, in
either case, in the unused amount of the applicable Commitment. On the terms and
subject to the conditions of this  Agreement,  each Borrowing shall be comprised
of the type of Loans,  and shall be made on the Business Day,  specified in such
Borrowing Request. In the case of other than Swing Line Loans, on or before 1:00
p.m. (New York City time) on such Business Day each Lender that has a Commitment
to make the Loans being  requested shall deposit with the  Administrative  Agent
same day funds in an amount equal to such  Lender's  Percentage of the requested
Borrowing.  Such  deposit  will be made to an account  which the  Administrative
Agent shall  specify from time to time by notice to the  Lenders.  To the extent
funds are received from the Lenders,  the  Administrative  Agent shall make such
funds  available to the  Borrower by wire  transfer to the accounts the Borrower
shall have specified in its Borrowing  Request.  No Lender's  obligation to make
any Loan shall be affected by any other Lender's failure to make any Loan.

         SECTION 2.3.2.  Swing Line Loans.  (a) By telephonic  notice,  promptly
followed  (within one Business  Day) by the  delivery of a confirming  Borrowing
Request,  to Scotiabank on or before 12:00 noon,  New York time, on the Business
Day the  proposed  Swing Line Loan is to be made,  the Borrower may from time to
time  irrevocably  request  that Swing Line  Loans be made by  Scotiabank  in an
aggregate  minimum  principal  amount of $500,000  and an  integral  multiple of
$100,000. All Swing Line Loans shall be made as Base Rate Loans and shall not be
entitled to be converted  into LIBO Rate Loans.  The proceeds of each Swing Line
Loan shall be made  available  by  Scotiabank,  by its close of  business on the
Business Day  telephonic  notice is received by it as provided in this clause to
the Borrower by wire transfer to the account the Borrower  shall have  specified
in its notice therefor.

                  (b) If

                          (i) any Swing Line Loan shall be outstanding  for more
                  than four Business Days;

                          (ii) any Swing Line Loan is or will be  outstanding on
                  a date when the  Borrower  requests  that a Revolving  Loan be
                  made; or

                          (iii) any Default shall occur and be continuing,

each Revolving Loan Lender (other than  Scotiabank)  irrevocably  agrees that it
will, at the request of Scotiabank, make a Revolving Loan (which shall initially
be funded as a Base Rate Loan) in an amount equal to such Lender's Percentage of
the  aggregate  principal  amount of all such Swing Line Loans then  outstanding
(such  outstanding  Swing Line Loans  hereinafter  referred to as the  "Refunded
Swing Line Loans"). On or before 1:00 p.m. (New York time) on

                                      -34-
<PAGE>



the first  Business  Day  following  receipt by each Lender of a request to make
Revolving  Loans as provided in the  preceding  sentence,  each  Revolving  Loan
Lender  shall  deposit  in an  account  specified  by  Scotiabank  the amount so
requested  in same day funds and such funds  shall be applied by  Scotiabank  to
repay the Refunded Swing Line Loans. At the time the aforementioned Lenders make
the above referenced  Revolving Loans,  Scotiabank shall be deemed to have made,
(in  consideration  of the making of the Refunded  Swing Line Loans),  Revolving
Loans in an amount equal to Scotiabank's  Percentage of the aggregate  principal
amount of the Refunded Swing Line Loans.  Upon the making (or deemed making,  in
the case of  Scotiabank)  of any Revolving  Loans  pursuant to this clause,  the
amount so funded shall become  outstanding  under such  Revolving  Loan Lender's
Revolving  Note and shall no longer be owed  under  the  Swing  Line  Note.  All
interest  payable with respect to any  Revolving  Loans made (or deemed made, in
the case of Scotiabank) pursuant to this clause shall be appropriately  adjusted
to reflect the period of time during which Scotiabank had outstanding Swing Line
Loans in respect of which such  Revolving  Loans were made.  Each Revolving Loan
Lender's obligation to make the Revolving Loans referred to in this clause shall
be absolute  and  unconditional  and shall not be affected by any  circumstance,
including  (i) any  set-off,  counterclaim,  recoupment,  defense or other right
which such Lender may have against Scotiabank, any Obligor or any Person for any
reason whatsoever;  (ii) the occurrence or continuance of any Default; (iii) any
adverse  change in the condition  (financial or otherwise) of any Obligor;  (iv)
the  acceleration  or  maturity of any  Obligations  or the  termination  of any
Commitment  after the  making of any Swing  Line  Loan;  (v) any  breach of this
Agreement  or any  other  Loan  Document  by  any  Person;  or  (vi)  any  other
circumstance,  happening or event  whatsoever,  whether or not similar to any of
the foregoing.

         SECTION 2.4.  Continuation  and Conversion  Elections.  By delivering a
Continuation/  Conversion Notice to the Administrative  Agent on or before 12:00
noon,  New York time,  on a Business  Day,  the  Borrower  may from time to time
irrevocably  elect,  on not less than one  Business  Days' notice in the case of
Base Rate Loans,  or three Business Days' notice in the case of LIBO Rate Loans,
and in either case not more than five Business  Days'  notice,  that all, or any
portion in an aggregate minimum amount of $1,000,000 and an integral multiple of
$1,000,000 be, in the case of Base Rate Loans, converted into LIBO Rate Loans or
be, in the case of LIBO Rate Loans,  converted into Base Rate Loans or continued
as LIBO Rate Loans (in the  absence  of  delivery  of a  Continuation/Conversion
Notice with respect to any LIBO Rate Loan at least three  Business Days (but not
more than five Business  Days) before the last day of the then current  Interest
Period  with  respect  thereto,  such LIBO Rate  Loan  shall,  on such last day,
automatically  convert to a Base Rate Loan);  provided,  however,  that (x) each
such  conversion  or  continuation  shall  be pro  rated  among  the  applicable
outstanding  Loans of all Lenders that have made such Loans,  and (y) no portion
of the  outstanding  principal  amount of any Loans may be  continued  as, or be
converted into, LIBO Rate Loans when any Default has occurred and is continuing.

         SECTION  2.5.  Funding.  Each Lender may, if it so elects,  fulfill its
obligation to make, continue or convert LIBO Rate Loans hereunder by causing one
of its foreign  branches or Affiliates  (or an  international  banking  facility
created by such  Lender)  to make or  maintain  such LIBO Rate  Loan;  provided,
however,  that such LIBO Rate Loan shall nonetheless be deemed to have been made
and to be held by such Lender,  and the obligation of the Borrower to repay such
LIBO Rate Loan shall  nevertheless  be to such  Lender  for the  account of such
foreign branch,

                                      -35-

<PAGE>



Affiliate or international  banking facility.  In addition,  the Borrower hereby
consents  and agrees  that,  for  purposes of any  determination  to be made for
purposes of Section 4.1, 4.2, 4.3 or 4.4, it shall be conclusively  assumed that
each Lender elected to fund all LIBO Rate Loans by purchasing Dollar deposits in
its LIBOR Office's interbank eurodollar market.

         SECTION 2.6. Issuance  Procedures.  By delivering to the Administrative
Agent an Issuance  Request on or before 12:00 noon, New York time, on a Business
Day,  the Borrower  may from time to time  irrevocably  request on not less than
three  nor more  than  ten  Business  Days'  notice,  in the case of an  initial
issuance  of a Letter of Credit and not less than  three  Business  Days'  prior
notice,  in the case of a request for the extension of the Stated Expiry Date of
a standby  Letter of Credit,  that an Issuer issue,  or extend the Stated Expiry
Date of, as the case may be, an irrevocable Letter of Credit in such form as may
be  requested  by the  Borrower  and  approved  by such  Issuer,  solely for the
purposes described in Section 7.1.8. Each Letter of Credit shall by its terms be
stated to expire on a date (its "Stated  Expiry Date") no later than the earlier
to occur of (i) the Revolving Loan Commitment  Termination Date and (ii) (unless
otherwise  agreed to by an Issuer,  in its sole  discretion)  two years from the
date of its issuance. Each Issuer will make available to the beneficiary thereof
the original of the Letter of Credit which it issues hereunder.

         SECTION 2.6.1. Other Lenders' Participation.  Upon the issuance of each
Letter  of Credit  issued by an Issuer  pursuant  hereto,  and  without  further
action,  each  Revolving Loan Lender (other than such Issuer) shall be deemed to
have  irrevocably  purchased,  to the extent of its Percentage to make Revolving
Loans,  a  participation  interest  in such  Letter  of  Credit  (including  the
Contingent Liability and any Reimbursement Obligation with respect thereto), and
such  Revolving  Loan  Lender  shall,  to the extent of its  Percentage  to make
Revolving  Loans,  be  responsible  for  reimbursing  promptly (and in any event
within one Business Day) the Issuer for Reimbursement Obligations which have not
been  reimbursed by the Borrower in accordance  with Section 2.6.3. In addition,
such  Revolving  Loan  Lender  shall,  to the extent of its  Percentage  to make
Revolving  Loans,  be  entitled  to  receive a ratable  portion of the Letter of
Credit fees  payable  pursuant to Section  3.3.3 with  respect to each Letter of
Credit  (other  than the  issuance  fees  payable to an Issuer of such Letter of
Credit  pursuant to the last sentence of Section 3.3.3) and of interest  payable
pursuant to Section 3.2 with  respect to any  Reimbursement  Obligation.  To the
extent  that  any  Revolving  Loan  Lender  has  reimbursed  any  Issuer  for  a
Disbursement,  such Lender  shall be entitled to receive its ratable  portion of
any amounts subsequently received (from the Borrower or otherwise) in respect of
such Disbursement.

         SECTION  2.6.2.  Disbursements.  An Issuer will notify the Borrower and
the  Administrative  Agent promptly of the presentment for payment of any Letter
of  Credit  issued  by such  Issuer,  together  with  notice  of the  date  (the
"Disbursement   Date")  such  payment  shall  be  made  (each  such  payment,  a
"Disbursement").  Subject to the terms and  provisions  of such Letter of Credit
and this  Agreement,  the  applicable  Issuer  shall  make such  payment  to the
beneficiary (or its designee) of such Letter of Credit.  Prior to 1:00 p.m., New
York time,  on the first  Business Day  following  the  Disbursement  Date,  the
Borrower  will  reimburse  the  Administrative  Agent,  for the  account  of the
applicable  Issuer,  for all amounts which such Issuer has disbursed  under such
Letter of Credit,  together with  interest  thereon at a rate per annum equal to
the rate

                                      -36-
<PAGE>



per annum then in effect for Base Rate Loans  (with the then  Applicable  Margin
for  Revolving  Loans  accruing on such amount)  pursuant to Section 3.2 for the
period  from the  Disbursement  Date  through  the  date of such  reimbursement.
Without  limiting in any way the foregoing and  notwithstanding  anything to the
contrary  contained  herein or in any  separate  application  for any  Letter of
Credit,  the Borrower hereby  acknowledges and agrees that it shall be obligated
to reimburse the applicable Issuer upon each Disbursement of a Letter of Credit,
and it shall be deemed to be the  obligor  for  purposes  of each such Letter of
Credit issued  hereunder  (whether the account party on such Letter of Credit is
the Borrower or a Subsidiary).

         SECTION  2.6.3.   Reimbursement.   The  obligation  (a   "Reimbursement
Obligation")  of the Borrower  under  Section  2.6.2 to reimburse an Issuer with
respect to each Disbursement (including interest thereon), and, upon the failure
of the Borrower to reimburse an Issuer,  each Revolving Loan Lender's obligation
under Section 2.6.1 to reimburse an Issuer,  shall be absolute and unconditional
under any and all circumstances and irrespective of any setoff,  counterclaim or
defense to payment which the Borrower or such Revolving Loan Lender, as the case
may be, may have or have had against  such Issuer or any Lender,  including  any
defense  based upon the failure of any  Disbursement  to conform to the terms of
the applicable  Letter of Credit (if, in such Issuer's good faith opinion,  such
Disbursement  is  determined  to be  appropriate)  or any  non-  application  or
misapplication  by the  beneficiary  of the  proceeds  of such Letter of Credit;
provided,  however,  that  after  paying  in full its  Reimbursement  Obligation
hereunder,  nothing herein shall  adversely  affect the right of the Borrower or
such Lender,  as the case may be, to commence any  proceeding  against an Issuer
for any wrongful  Disbursement made by such Issuer under a Letter of Credit as a
result of acts or omissions  constituting  gross negligence or wilful misconduct
on the part of such Issuer.

         SECTION 2.6.4. Deemed Disbursements. Upon the occurrence and during the
continuation  of any Default  under Section  8.1.9 or upon  notification  by the
Administrative  Agent (acting at the  direction of the Required  Lenders) to the
Borrower of its  obligations  under this Section,  following the  occurrence and
during the continuation of any other Event of Default,

                  (a) the  aggregate  Stated  Amount  of all  Letters  of Credit
         shall,  without  demand  upon or  notice to the  Borrower  or any other
         Person, be deemed to have been paid or disbursed by the Issuers of such
         Letters  of Credit  (notwithstanding  that such  amount may not in fact
         have been paid or disbursed); and

                  (b) the Borrower shall be  immediately  obligated to reimburse
         the Issuers for the amount  deemed to have been so paid or disbursed by
         such Issuers.

Amounts  payable by the Borrower  pursuant to this Section shall be deposited in
immediately available funds with the Administrative Agent and held as collateral
security for the Reimbursement Obligations. When all Defaults giving rise to the
deemed   disbursements  under  this  Section  have  been  cured  or  waived  the
Administrative  Agent shall  return to the  Borrower all amounts then on deposit
with the  Administrative  Agent  pursuant  to this  Section  which have not been
applied to the satisfaction of the Reimbursement Obligations.


                                      -37-
<PAGE>



         SECTION 2.6.5. Nature of Reimbursement Obligations.  The Borrower, each
other Obligor and, to the extent set forth in Section 2.6.1, each Revolving Loan
Lender shall assume all risks of the acts,  omissions or misuse of any Letter of
Credit by the  beneficiary  thereof.  No Issuer (except to the extent of its own
gross negligence or wilful misconduct) shall be responsible for:

                  (a) the form, validity, sufficiency,  accuracy, genuineness or
         legal effect of any Letter of Credit or any  document  submitted by any
         party in connection  with the  application for and issuance of a Letter
         of Credit, even if it should in fact prove to be in any or all respects
         invalid, insufficient, inaccurate, fraudulent or forged;

                  (b) the form, validity, sufficiency,  accuracy, genuineness or
         legal effect of any instrument  transferring or assigning or purporting
         to  transfer  or assign a Letter of  Credit or the  rights or  benefits
         thereunder or the proceeds thereof in whole or in part, which may prove
         to be invalid or ineffective for any reason;

                  (c) failure of the beneficiary to comply fully with conditions
         required in order to demand payment under a Letter of Credit;

                  (d) errors, omissions, interruptions or delays in transmission
         or  delivery  of any  messages,  by mail,  cable,  telegraph,  telex or
         otherwise; or

                  (e) any loss or delay in the  transmission or otherwise of any
         document  or draft  required  in order to make a  Disbursement  under a
         Letter of Credit.

None of the foregoing shall affect,  impair or prevent the vesting of any of the
rights or powers granted to any Issuer or any Revolving  Loan Lender  hereunder.
In furtherance and not in limitation or derogation of any of the foregoing,  any
action  taken or  omitted  to be  taken  by an  Issuer  in good  faith  (and not
constituting gross negligence or willful  misconduct) shall be binding upon each
Obligor and each such  Secured  Party,  and shall not put such Issuer  under any
resulting liability to any Obligor or any Secured Party, as the case may be.

         SECTION 2.7.  Notes.  Each Lender's  Loans under a Commitment  shall be
evidenced by a Note  payable to the order of such Lender in a maximum  principal
amount equal to such Lender's Percentage of the original  applicable  Commitment
Amount. The Borrower hereby irrevocably authorizes each Lender to make (or cause
to be made) appropriate notations on the grid attached to such Lender's Note (or
on any  continuation of such grid),  which  notations,  if made, shall evidence,
inter alia, the date of, the outstanding principal of, and the interest rate and
Interest Period applicable to the Loans evidenced thereby.  Such notations shall

                                    (B) all  such  voluntary  prepayments  shall
                           require  at least one but no more than five  Business

                           aggregate   minimum   amount  of  $1,000,000  and  an
                           integral  multiple of $1,000,000  and, in the case of

                  (b) On each date when the sum of (i) the aggregate outstanding
         principal  amount of all Revolving  Loans and Swing Line Loans and (ii)
         the aggregate amount of all Letter of Credit  Outstandings  exceeds the
         Revolving  Loan  Commitment  Amount (as it may be reduced  from time to
         time,  including  pursuant to Section 2.2),  the Borrower  shall make a
         mandatory prepayment of all the Revolving Loans or all Swing Line Loans
         (or both) and, if necessary, give cash collateral to the Administrative
         Agent pursuant to an agreement satisfactory to the Administrative Agent
         to collateralize Letter of Credit Outstandings,  in an aggregate amount
         equal to such excess. On the first Business Day following the Effective
         Date, the Borrower shall make a mandatory prepayment of Revolving Loans
         (which prepayment shall not result in a reduction of the Revolving Loan
         Commitment  Amount)  in an  aggregate  principal  amount  of  at  least
         $35,200,000.

                  (c)  Concurrently  with the receipt (or deemed receipt) of any
         Net Proceeds by the Borrower or any of its Restricted Subsidiaries, the
         Borrower  shall  make a  mandatory  prepayment  of the  Loans (i) in an
         amount equal to 100% of the Net  Proceeds  with respect to Net Proceeds
         described  in clauses (b),  (c) and (d) of the  definition  thereof and
         (ii)  50% of  such  Net  Proceeds  with  respect  to the  Net  Proceeds
         described in clause (a) of the definition  thereof, in each case, to be
         applied as set forth in Section  3.1.2.  The  Borrower  will,  prior to
         prepaying the Loans,  give the  Administrative  Agent telephone  notice
         (promptly  confirmed  in writing)  requesting  that the  Administrative
         Agent  provide  notice of such  prepayment  to each Lender  entitled to
         receive any portion of such prepayment.

                  (d) On the Stated Maturity Date and on each Quarterly  Payment
         Date  occurring  during any period set forth below,  the Borrower shall
         make a  scheduled  repayment  of the  aggregate  outstanding  principal
         amount of:

                           (i) the  Original  Acquisition  Loans,  if any, in an

Each  prepayment  of any Loans made  pursuant to this  Section  shall be without
premium or penalty,  except as may be required by Section 4.4. No  prepayment of
principal of any Revolving  Loans or Swing Line Loans  pursuant to clause (a) or
(b) shall cause a reduction in the Revolving Loan Commitment Amount or the Swing
Line Loan Commitment Amount, as the case may be.

         SECTION  3.1.2.  Application.  Amounts  prepaid shall be applied as set
forth in this Section.

         prepayment or repayment,  first, to the principal  amount thereof being
         maintained  as Base Rate Loans,  and second,  to the  principal  amount
         thereof being maintained as LIBO Rate Loans;  provided,  that mandatory
         prepayments  of LIBO Rate Loans made  pursuant to clause (c) of Section
         3.1.1,  if not made on the last day of the Interest Period with respect
         thereto,  shall be (i) prepaid subject to the provisions of Section 4.4
         (together  with a payment  of all  accrued  interest)  or (ii) upon the
         written  request  of the  Borrower,  so long as no  Default or Event of
         Default has  occurred and is  continuing,  the last day of the relevant
         Interest Period so long as the funds  representing  such prepayment are

         documentation  in form and  substance  reasonably  satisfactory  to the
         Administrative Agent.

                  (b) Each  prepayment  of Loans made  pursuant to clause (c) of
         Section  3.1.1  shall  be  applied  (i)  first,  (A)  prior  to the New
         Acquisition  Conversion Date, as applicable,  pro rata to the mandatory
         prepayment  of  the  outstanding   principal  amount  of  all  Original
         Acquisition  Loans,  Term B Loans or New Acquisition  Loans, and (B) on
         and  after  the  New  Acquisition  Conversion  Date,  to the  mandatory
         prepayment of the outstanding  principal amount of all Term Loans (with
         the amount of such  prepayment  of the Term Loans being  applied to all
         remaining amortization payments of each Term Loan,

                                      -42-

         pro rata among all such outstanding  Term Loans),  until all Term Loans
         have been paid in full,  and except that with  respect to the amount of
         any such  prepayment that is allocated to the then  outstanding  Term B
         Loans,  each such Term B Loan Lender shall have the right to refuse any
         such  prepayment  by  giving  written  notice  of such  refusal  to the
         Borrower  within  five  Business  Days after such Term B Loan  Lender's
         receipt of notice from the Administrative Agent of such prepayment (and
         the  Borrower  shall not prepay any such Term B Loans  until such tenth
         Business Day or such time as the Borrower  receives written notice from
         such Term B Loan Lender that it consents to such prepayment,  whichever
         is earlier). 50% of any prepayment so refused shall be applied pro rata
         to the remaining  Original  Acquisition  Loans, Term B Loans (of Term B
         Loan Lenders that did not refuse such prepayment  pursuant  hereto) and
         New Acquisition  Loans, and the Borrower shall retain the remaining 50%
         of any  prepayment  so refused;  (ii) second,  once all Term Loans have
         been  repaid in full and all Term  Loan  Commitment  Amounts  have been
         reduced to $0, all  prepayments of Loans made pursuant to clause (c) of
         Section  3.1.1  shall be applied to the  repayment  of any  outstanding
         Revolving  Loans and, in the case of Asset Sales only,  a reduction  of
         the Revolving Loan Commitment Amount in accordance with Section 2.2.2.

         SECTION 3.2. Interest Provisions. Interest on the outstanding principal
amount of Loans shall accrue and be payable in accordance with this Section 3.2.

         SECTION  3.2.1.  Rates.  Subject  to  Section  2.3.2,  pursuant  to  an
appropriately delivered Borrowing Request or Continuation/Conversion Notice, the
Borrower may elect that Loans  comprising a Borrowing  accrue interest at a rate
per annum:

                  (a) on that  portion  maintained  from  time to time as a Base
         Rate  Loan,  equal to the sum of the  Alternate  Base Rate from time to
         time in effect plus the Applicable Margin; provided that all Swing Line
         Loans shall always  accrue  interest at the then  effective  Applicable
         Margin for Revolving Loans maintained as Base Rate Loans; and

                  (b) on that  portion  maintained  as a LIBO Rate Loan,  during
         each Interest Period applicable  thereto,  equal to the sum of the LIBO
         Rate (Reserve  Adjusted) for such Interest  Period plus the  Applicable
         Margin.

         All LIBO Rate Loans shall bear  interest  from and  including the first
day of the  applicable  Interest  Period to (but not  including) the last day of
such Interest  Period at the interest rate determined as applicable to such LIBO
Rate Loan.

         SECTION 3.2.2. Post-Maturity Rates. After the date any principal amount
of any Loan or  Reimbursement  Obligation  is due and  payable  (whether  on the
Stated  Maturity  Date,  upon  acceleration  or  otherwise),  or after any other
monetary  Obligation  of the  Borrower  shall have become due and  payable,  the
Borrower shall pay, but only to the extent permitted by law,  interest (after as
well as  before  judgment)  on such  amounts  at a rate per  annum  equal to the
Alternate Base Rate from time to time in effect plus the Applicable  Margin then
in effect plus a margin of 2%.

         SECTION 3.2.3.  Payment Dates.  Interest  accrued on each Loan shall be
payable, without duplication:

                  (a)  on the Stated Maturity Date therefor;

                  (b) on the date of any payment or  prepayment,  in whole or in
         part, of principal  outstanding on such Loan on the principal amount so
         paid or prepaid;

                  (c) with respect to Base Rate Loans, on each Quarterly Payment
         Date occurring after the Effective Date;

                  (d) with  respect to LIBO Rate Loans,  on the last day of each
         applicable  Interest  Period (and, if such Interest Period shall exceed
         three  months,  on the  date  occurring  on each  three-month  interval
         occurring after the first day of such Interest Period); and

                  (e) on that portion of any Loans the Stated  Maturity  Date of
         which  is   accelerated   pursuant  to  Section  8.2  or  Section  8.3,
         immediately upon such acceleration.

Interest  accrued  on Loans or other  monetary  Obligations  arising  under this
Agreement  or any other  Loan  Document  after  the date such  amount is due and
payable  (whether on the Stated Maturity Date,  upon  acceleration or otherwise)
shall be payable upon demand.

         SECTION 3.3.  Fees.  The  Borrower  agrees to pay the fees set forth in
this Section 3.3. All such fees shall be non-refundable.

         SECTION  3.3.1.  Commitment  Fee.  The  Borrower  agrees  to pay to the
Administrative  Agent for the account of each Lender,  for the period (including
any portion  thereof when any of its  Commitments are suspended by reason of the
Borrower's  inability to satisfy any  condition of Article V)  commencing on the
Effective Date and  continuing  through the  applicable  Commitment  Termination
Date,  a  commitment  fee in an amount equal to the  Applicable  Commitment  Fee
Margin, in each case on such Lender's Percentage of the sum of the average daily
unused  portion of the  applicable  Commitment  Amount  (net of Letter of Credit
Outstandings,  in the  case  of  the  Revolving  Loan  Commitment  Amount.)  All
commitment  fees payable  pursuant to this Section shall be calculated on a year
comprised of 360 days and payable by the  Borrower in arrears on each  Quarterly
Payment Date,  commencing  with the first  Quarterly  Payment Date following the
Effective Date, on the New Acquisition Conversion Date and on the Revolving Loan
Commitment Termination Date. The making of Swing Line Loans shall not constitute
usage of the  Revolving  Loan  Commitment  with  respect to the  calculation  of
commitment fees to be paid by the Borrower to the Lenders.

         SECTION  3.3.2.  Agent's  Fee.  The  Borrower  agrees  to  pay  to  the
Administrative  Agent,  for its own account,  the fees in the amounts and on the
dates set forth in the Fee Letter.

         SECTION 3.3.3.  Letter of Credit Fee. The Borrower agrees to pay to the
Administrative Agent, for the pro rata account of the applicable Issuer and each
Revolving Loan Lender, a

                                      -44-
<PAGE>



Letter of Credit fee in an amount per annum equal to the then Applicable  Margin
for  Revolving  Loans  maintained  as LIBO Rate Loans,  multiplied by the Stated
Amount of each such Letter of Credit, such fees being payable,  upon issuance of
each  Letter of Credit  (for the period from the date of issuance to the earlier
of the expiration  date of the applicable  Letter of Credit and the  immediately
succeeding  Quarterly  Payment  Date),  quarterly  in arrears on each  Quarterly
Payment Date. The Borrower  further  agrees to pay to the  applicable  Issuer in
advance on the date of issuance or  extension  of each Letter of Credit (for the
period from the date of issuance  to the earlier of the  expiration  date of the
applicable  Letter of Credit and the immediately  succeeding  Quarterly  Payment
Date,  and  thereafter  quarterly in arrears on each  Quarterly  Payment Date) a
fronting fee as  specified  in the Fee Letter or as  otherwise  agreed to by the
Borrower and such Issuer.


                                   ARTICLE IV

                     CERTAIN LIBO RATE AND OTHER PROVISIONS

         SECTION 4.1. LIBO Rate Lending Unlawful.  If any Lender shall determine
(which determination shall, upon notice thereof to the Borrower and the Lenders,
be  conclusive  and binding on the  Borrower)  that the  introduction  of or any
change in or in the interpretation of any law makes it unlawful,  or any central
bank or other  governmental  authority  asserts  that it is  unlawful,  for such
Lender to make, continue or maintain any Loan as, or to convert any Loan into, a
LIBO Rate Loan, the  obligations of such Lender to make,  continue,  maintain or
convert any such LIBO Rate Loan shall,  upon such  determination,  forthwith  be
suspended  until such  Lender  shall  notify the  Administrative  Agent that the
circumstances  causing such suspension no longer exist, and all outstanding LIBO
Rate Loans of such Lender  shall  automatically  convert into Base Rate Loans at
the end of the then current Interest Periods with respect thereto or sooner,  if
required by such law or assertion.

         SECTION 4.2. Deposits  Unavailable.  If the Administrative  Agent shall
have determined that:

                  (a)  Dollar  deposits  in the  relevant  amount  and  for  the
         relevant  Interest  Period  are  not  available  to it in its  relevant
         market; or

                  (b) by reason of circumstances affecting it's relevant market,
         adequate  means  do  not  exist  for  ascertaining  the  interest  rate
         applicable hereunder to LIBO Rate Loans,

then, upon notice from the Administrative Agent to the Borrower and the Lenders,
the  obligations  of all  Lenders  under  Section 2.3 and Section 2.4 to make or
continue  any Loans as, or to convert  any Loans  into,  LIBO Rate  Loans  shall
forthwith be suspended until the Administrative  Agent shall notify the Borrower
and the Lenders that the circumstances causing such suspension no longer exist.


                                      -45-
<PAGE>



         SECTION 4.3.  Increased LIBO Rate Loan Costs,  etc. The Borrower agrees
to reimburse  each Lender for any increase in the cost to such Lender of, or any
reduction  in the amount of any sum  receivable  by such  Lender in respect  of,
making,  continuing or maintaining  (or of its  obligation to make,  continue or
maintain) any Loans as, or of converting  (or of its  obligation to convert) any
Loans into,  LIBO Rate Loans that arise in connection with any change in, or the
introduction,  adoption,  effectiveness,  interpretation,   reinterpretation  or
phase-in after the date hereof of, any law or regulation,  directive, guideline,
decision  or  request  (whether  or not  having  the force of law) of any court,
central bank, regulator or other governmental authority, except for such changes
with respect to increased capital costs and taxes which are governed by Sections
4.5 and 4.6, respectively.  Such Lender shall promptly notify the Administrative
Agent and the  Borrower in writing of the  occurrence  of any such  event,  such
notice to state, in reasonable  detail,  the reasons therefor and the additional
amount  required  fully to  compensate  such Lender for such  increased  cost or
reduced  amount.  Such  additional  amounts  shall be  payable  by the  Borrower
directly to such Lender within five days (with at least one day being a Business
Day) of its receipt of such  notice,  and such notice  shall,  in the absence of
manifest error, be conclusive and binding on the Borrower.

         Without  limiting the foregoing,  in the event that, as a result of any
such  change,  introduction,  adoption or the like  described  above,  the LIBOR
Reserve Percentage decreases for any Lender's LIBO Rate Loans, such Lender shall
give  prompt  notice  thereof  in writing  to the  Administrative  Agent and the
Borrower.  On the first Business Day following delivery of such notice, the LIBO
Rate (Reserve  Adjusted)  attributable to such Lender's LIBO Rate Loans shall be
adjusted to give the Borrower the benefit of such  decrease (for so long as such
decrease shall remain in effect).

         SECTION 4.4.  Funding  Losses.  In the event any Lender shall incur any
loss or  expense  (including  any loss or  expense  incurred  by  reason  of the
liquidation or  reemployment  of deposits or other funds acquired by such Lender
to make,  continue or maintain any portion of the  principal  amount of any Loan
as, or to convert any portion of the  principal  amount of any Loan into, a LIBO
Rate Loan) as a result of:

                  (a) any conversion or repayment or prepayment of the principal
         amount of any LIBO Rate Loans on a date other than the  scheduled  last
         day of the Interest  Period  applicable  thereto,  whether  pursuant to
         Section 3.1 or otherwise;

                  (b) any Loans not being made as LIBO Rate Loans in  accordance
         with the Borrowing Request therefor; or

                  (c) any Loans not being  continued as, or converted into, LIBO
         Rate  Loans  in  accordance  with  the  Continuation/Conversion  Notice
         therefor,

then, upon the written notice of such Lender to the Borrower (with a copy to the
Administrative  Agent),  the  Borrower  shall,  within  five days of its receipt
thereof,  pay  directly to such  Lender  such amount as will (in the  reasonable
determination of such Lender) reimburse such Lender for

                                      -46-
<PAGE>



such loss or expense.  Such written notice (which shall include  calculations in
reasonable  detail) shall, be rebuttably  presumptive  evidence of the amount of
such loss or expense.

         SECTION  4.5.  Increased  Capital  Costs.  If  any  change  in,  or the
introduction,  adoption,  effectiveness,  interpretation,   reinterpretation  or
phase-in of, any law or regulation,  directive,  guideline,  decision or request
(whether or not having the force of law) of any court,  central bank,  regulator
or other  governmental  authority  affects or would affect the amount of capital
required or expected to be  maintained by any Lender  (including  any Issuer) or
any Person  controlling such Lender,  and such Lender  determines (in good faith
but in its sole and absolute  discretion) that the rate of return on its or such
controlling  Person's  capital as a consequence of the  Commitments or the Loans
made, or the Letters of Credit issued by or  participated  in, by such Lender is
reduced to a level below that which such Lender or such controlling Person could
have achieved but for the occurrence of any such circumstance, then, in any such
case upon notice from time to time by such Lender to the Borrower,  the Borrower
shall immediately pay directly to such Lender additional  amounts  sufficient to
compensate such Lender or such controlling  Person for such reduction in rate of
return.  A statement of such Lender as to any such additional  amount or amounts
(including  calculations  thereof in  reasonable  detail)  shall,  be rebuttably
presumptive  evidence of the amount of such loss or expense. In determining such
amount,  such Lender may use any method of averaging and attribution that it (in
its sole and absolute discretion) shall deem applicable.

         SECTION 4.6.  Taxes.  (a) Any and all payments by the Borrower and each
other  Obligor under this  Agreement and each other Loan Document  shall be made
without  setoff,  counterclaim  or other  defense,  and free and clear  of,  and
without deduction or withholding for or on account of, any Taxes,  except to the
extent such Taxes are  imposed by law. In the event that any Taxes are  required
by law to be deducted or  withheld  from any payment  required to be made by the
Borrower or any other Obligor to or on behalf of the Administrative Agent or any
Lender hereunder or under any other Loan Document, then:

                           (i)   subject  to  clause  (f),  if  such  Taxes  are
                  Non-Excluded  Taxes,  the  amount  of such  payment  shall  be
                  increased as may be necessary  such that such payment is made,
                  after  withholding  or  deduction  for or on  account  of such
                  Taxes,  in an amount that is not less than the amount provided
                  for herein or in such other Loan Document; and

                           (ii) the Borrower  shall  withhold the full amount of
                  such Taxes from such payment (as increased  pursuant to clause
                  (a)  (i))  and  shall  pay  such  amount  to the  Governmental
                  Authority  imposing such Taxes in accordance  with  applicable
                  law.

                  (b) In addition, the Borrower and each other Obligor shall pay
         any and all Other Taxes imposed to the relevant Governmental  Authority
         imposing such Other Taxes in accordance with applicable law.

                  (c) As promptly as practicable  after the payment of any Taxes
         or Other  Taxes,  and in any event  within 45 days of any such  payment
         being due, the Borrower shall

                                      -47-
<PAGE>



         furnish to the Administrative Agent a copy of an official receipt (or a
         certified  copy thereof)  evidencing the payment of such Taxes or Other
         Taxes. The Administrative  Agent shall make copies thereof available to
         any Lender upon request therefor.

                  (d) Subject to clause (f), the Borrower  shall  indemnify  the
         Administrative  Agent and each  Lender for any  Non-Excluded  Taxes and
         Other Taxes  levied,  imposed or  assessed on (and  whether or not paid
         directly  by) the  Administrative  Agent or such Lender (and whether or
         not such  Non-Excluded  Taxes or Other Taxes are  correctly  or legally
         asserted by the relevant Governmental Authority).  Promptly upon having
         knowledge  that any such  Non-Excluded  Taxes or Other  Taxes have been
         levied,  imposed or assessed,  and promptly upon notice  thereof by the
         Administrative  Agent  or any  Lender,  the  Borrower  shall  pay  such
         Non-Excluded Taxes or Other Taxes directly to the relevant Governmental
         Authority (provided, however, that neither the Administrative Agent nor
         any Lender shall be under any  obligation to provide any such notice to
         the  Borrower).   In  addition,   the  Borrower  shall   indemnify  the
         Administrative Agent and each Lender for any incremental Taxes that may
         become payable by the Administrative Agent or any Lender as a result of
         any  failure  of  the  Borrower  to  pay  any  Taxes  when  due  to the
         appropriate  Governmental Authority or to deliver to the Administrative
         Agent, pursuant to clause (c), documentation  evidencing the payment of
         Taxes or Other Taxes. With respect to indemnification  for Non-Excluded
         Taxes and Other Taxes actually paid by the Administrative  Agent or any
         Lender or the  indemnification  provided in the  immediately  preceding
         sentence,  such indemnification  shall be made within 30 days after the
         date the Administrative Agent or such Lender, as the case may be, makes
         written demand  therefor.  The Borrower  acknowledges  that any payment
         made to the Administrative Agent or any Borrower or to any Governmental
         Authority in respect of the indemnification obligations of the Borrower
         provided in this clause shall  constitute a payment in respect of which
         the provisions of clause (a) and this clause shall apply.

                  (e)  Each  Non-U.S.  Lender,  on or prior to the date on which
         such non-U.S.  Lender becomes a Lender hereunder (and from time to time
         thereafter  upon the  request  of the  Borrower  or the  Administrative
         Agent, but only for so long as such non-U.S. Lender is legally entitled
         to do so), shall deliver to the Borrower and the  Administrative  Agent
         either

                           (i) (x) two  duly  completed  copies  of  either  (A)
                  Internal  Revenue  Service Form 1001 or (B)  Internal  Revenue
                  Service Form 4224, or in either case an  applicable  successor
                  form,  and  (y) a duly  completed  copy  of  Internal  Revenue
                  Service Form W-8 or W-9 or applicable successor form; or

                           (ii) in the  case of a  Non-U.S.  Lender  that is not
                  legally  entitled  to  deliver  either  form  listed in clause
                  (e)(i)(x),  (x) a certificate of a duly authorized  officer of
                  such Non-U.S.  Lender to the effect that such Non-U.S.  Lender
                  is not (A) a "bank" within the meaning of Section 881(c)(3)(A)
                  of the Code,  (B) a "10 percent  shareholder"  of the Borrower
                  within the meaning of Section 881(c)(3)(B) of the Code, or (C)
                  a controlled  foreign  corporation  receiving  interest from a
                  related

                                      -48-
<PAGE>



                  person within the meaning of Section  881(c)(3)(C) of the Code
                  (such  certificate,  an "Exemption  Certificate")  and (y) two
                  duly completed  copies of Internal Revenue Service Form W-8 or
                  applicable successor form.

                  (f) The  Borrower  shall  not be  obligated  to  gross  up any
         payments to any Lender  pursuant to clause (a)(i),  or to indemnify any
         Lender  pursuant  to clause (d),  in respect of United  States  federal
         withholding  taxes to the extent imposed as a result of (i) the failure
         of such Lender to deliver to the  Borrower  the form or forms and/or an
         Exemption Certificate, as applicable to such Lender, pursuant to clause
         (e),  (ii)  such  form  or  forms  and/or  Exemption   Certificate  not
         establishing a complete exemption from U.S. federal  withholding tax or
         the  information  or  certifications  made  therein by the Lender being
         untrue or inaccurate on the date delivered in any material respect,  or
         (iii) the Lender  designating  a successor  lending  office at which it
         maintains  its Loans  which has the  effect of causing  such  Lender to
         become  obligated  for tax  payments  in  excess  of  those  in  effect
         immediately  prior to such  designation;  provided,  however,  that the
         Borrower shall be obligated to gross up any payments to any such Lender
         pursuant to clause (a)(i), and to indemnify any such Lender pursuant to
         clause (d), in respect to United States  federal  withholding  taxes if
         (i) any  such  failure  to  deliver  a form or  forms  or an  Exemption
         Certificate  or  the  failure  of  such  form  or  forms  or  Exemption
         Certificate  to  establish  a  complete  exemption  from  U.S.  federal
         withholding  tax or inaccuracy or untruth  contained  therein  resulted
         from a change in any applicable  statute,  treaty,  regulation or other
         applicable law or any interpretation of any of the foregoing  occurring
         after the date  hereof,  which  change  rendered  such Lender no longer
         legally entitled to deliver such form or forms or Exemption Certificate
         or otherwise  ineligible  for a complete  exemption  from U.S.  federal
         withholding tax, or rendered the information or certifications  made in
         such form or forms or Exemption  Certificate  untrue or inaccurate in a
         material respect, (ii) the redesignation of the Lender's lending office
         was made at the  request of the  Borrower  or (iii) the  obligation  to
         gross up payments to any such  Lender  pursuant to clause  (a)(i) or to
         indemnify any such Lender  pursuant to clause (d) is with respect to an
         Assignee  Lender  that  becomes  an  Assignee  Lender as a result of an
         assignment made at the request of the Borrower.

         SECTION 4.7. Payments,  Computations,  etc. Unless otherwise  expressly
provided,  all payments by the Borrower  pursuant to this Agreement,  the Notes,
each Letter of Credit or any other Loan  Document  shall be made by the Borrower
to the Administrative  Agent for the pro rata account of the Lenders entitled to
receive  such  payment.   All  such   payments   required  to  be  made  to  the
Administrative  Agent shall be made, without setoff,  deduction or counterclaim,
not later  than  1:00  p.m.,  New York  time,  on the date  due,  in same day or
immediately  available funds, to such account as the Administrative  Agent shall
specify from time to time by notice to the Borrower.  Funds  received after that
time shall be deemed to have been  received by the  Administrative  Agent on the
next succeeding  Business Day. The Administrative  Agent shall promptly remit in
same day funds to each Lender its share,  if any, of such  payments  received by
the Administrative Agent for the account of such Lender. All interest (including
interest  on LIBO Rate  Loans)  and fees shall be  computed  on the basis of the
actual  number of days  (including  the first  day but  excluding  the last day)
occurring during the period for which such

                                      -49-
<PAGE>



interest or fee is payable over a year comprised of 360 days (or, in the case of
interest on a Base Rate Loan  (calculated at other than the Federal Funds Rate),
365 days or, if  appropriate,  366 days).  Whenever any payment to be made shall
otherwise  be due on a day  which is not a  Business  Day,  such  payment  shall
(except  as  otherwise  required  by clause  (c) of the  definition  of the term
"Interest  Period")  be made  on the  next  succeeding  Business  Day  and  such
extension of time shall be included in computing  interest and fees,  if any, in
connection with such payment.

         SECTION  4.8.  Sharing  of  Payments.  If any Lender  shall  obtain any
payment or other recovery  (whether  voluntary,  involuntary,  by application of
setoff or otherwise) on account of any Loan or Reimbursement  Obligation  (other
than pursuant to the terms of Section 4.3, 4.4, 4.5 or 4.6) in excess of its pro
rata share of payments  then or therewith  obtained by all Lenders,  such Lender
shall purchase from the other Lenders such  participations  in Credit Extensions
made by them as shall be necessary to cause such purchasing  Lender to share the
excess payment or other recovery ratably with each of them;  provided,  however,
that if all or any portion of the excess payment or other recovery is thereafter
recovered from such purchasing  Lender, the purchase shall be rescinded and each
Lender which has sold a  participation  to the purchasing  Lender shall repay to
the purchasing  Lender the purchase price to the ratable extent of such recovery
together with an amount equal to such selling  Lender's ratable share (according
to the proportion of:

                  (a) the amount of such selling Lender's required  repayment to
         the purchasing Lender

to

                  (b) total amount so recovered from the  purchasing  Lender) of
         any interest or other amount paid or payable by the  purchasing  Lender
         in respect of the total amount so recovered.  The Borrower  agrees that
         any Lender so purchasing a  participation  from another Lender pursuant
         to this Section may, to the fullest extent  permitted by law,  exercise
         all its  rights of payment  (including  pursuant  to Section  4.9) with
         respect  to such  participation  as  fully as if such  Lender  were the
         direct creditor of the Borrower in the amount of such participation. If
         under any applicable  bankruptcy,  insolvency or other similar law, any
         Lender  receives  a  secured  claim in lieu of a setoff  to which  this
         Section applies, such Lender shall, to the extent practicable, exercise
         its rights in respect of such secured claim in a manner consistent with
         the rights of the Lenders  entitled  under this Section to share in the
         benefits of any recovery on such secured claim.

         SECTION 4.9. Setoff.  Each Lender shall, upon the occurrence and during
the  continuance of any Default  described in clauses (a) through (d) of Section
8.1.9 or, with the consent of the  Required  Lenders,  upon the  occurrence  and
during  the  continuance  of any  other  Event of  Default,  have  the  right to
appropriate and apply to the payment of the Obligations  owing to it (whether or
not then due), and (as security for such Obligations) the Borrower hereby grants
to each Lender a continuing security interest in, any and all balances, credits,
deposits,  accounts or moneys of the Borrower then or thereafter maintained with
such Lender;  provided,  however,  that any such  appropriation  and application
shall be subject to the provisions of

                                      -50-
<PAGE>



Section  4.8.  Each  Lender  agrees  promptly  to notify  the  Borrower  and the
Administrative  Agent after any such setoff and application made by such Lender;
provided,  however,  that the failure to give such  notice  shall not affect the
validity of such setoff and  application.  The rights of each Lender  under this
Section are in addition to other rights and remedies  (including other rights of
setoff under applicable law or otherwise) which such Lender may have.

         SECTION 4.10.  Replacement of Lender. Each Lender agrees that, upon the
occurrence of any event set forth in Sections 4.1, 4.3, 4.5, or 4.6, such Lender
will use  reasonable  efforts to book and maintain its Loans through a different
lending  office or to transfer its Loans to an Affiliate  with the  objective of
avoiding  or  minimizing  the  consequences  of such event;  provided  that such
booking  or  transfer  is  not  otherwise  disadvantageous  to  such  Lender  as
determined by such Lender in its sole and absolute discretion. If any Lender has
demanded to be paid  additional  amounts  pursuant to Sections  4.1, 4.3, 4.5 or
4.6, and the payment of such additional  amounts are, and are likely to continue
to be, more onerous in the reasonable judgment of the Borrower than with respect
to the other Lenders, then the Borrower shall have the right at any time when no
Default or Event of Default shall have occurred and be continuing to seek one or
more financial  institutions  which are not Affiliates of the Borrower  (each, a
"Replacement Lender") to purchase with the written consent of the Administrative
Agent  (which  consent  shall not be (x) required if such  proposed  Replacement
Lender is already a Lender,  or an  Affiliate of a Lender,  or (y)  unreasonably
delayed or withheld) the  outstanding  Loans and Commitments of such Lender (the
"Affected  Lender"),  and if the  Borrower  locates a  Replacement  Lender,  the
Affected Lender shall, upon

                          (i) prior written notice to the Administrative Agent,

                          (ii)  (A)  payment  to  the  Affected  Lender  of  the
                  purchase  price agreed between it and the  Replacement  Lender
                  (or, failing such agreement, a purchase price in the amount of
                  the  outstanding  principal  amount of the  Affected  Lender's
                  Loans and accrued  interest thereon to the date of payment) by
                  the Replacement Lender plus (B) payment by the Borrower of all
                  amounts  (other than  principal and interest)  then due to the
                  Affected Lender or accrued for its account  hereunder or under
                  any other Loan Document,

                          (iii)  satisfaction  of the  provisions  set  forth in
                  Section 10.11.1, and

                          (iv) payment by the  Borrower to the  Affected  Lender
                  and the Administrative  Agent of all reasonable  out-of-pocket
                  expenses in connection  with such  assignment  and  assumption
                  (including the processing fees described in Section 10.11.1),

assign and delegate all its rights and obligations  under this Agreement and any
other Loan Document to which it is a party (including its outstanding  Loans) to
the  Replacement   Lender  (such   assignment  to  be  made  without   recourse,
representation or warranty), and the Replacement Lender shall assume such rights
and  obligations,  whereupon the  Replacement  Lender shall in  accordance  with
Section  10.11.1  become a party to each Loan  Document  to which  the  Affected
Lender  is a party  and  shall  have  the  rights  and  obligations  of a Lender
thereunder and the

                                      -51-

Affected Lender shall be released from its obligations  hereunder and each other
Loan Document to the extent of such assignment and delegation.

respective properties, businesses, assets or revenues, which could

                                      -60-

reasonably be expected to have a Material  Adverse Effect except as disclosed in
Item 6.7 of the  Disclosure  Schedule  or (ii)  which  purports  to  affect  the
legality,  validity  or  enforceability  of this  Agreement  or any  other  Loan

         SECTION 6.8.  Subsidiaries.  The Borrower has no  Subsidiaries,  except
those Subsidiaries

                  (a)  which  are  identified  in  Item  6.8 of  the  Disclosure
         Schedule; or

                  (b) which are permitted to have been  organized or acquired in

         SECTION    6.11.    Pension    and    Welfare    Plans.    During   the
twelve-consecutive-month  period prior to the date of the execution and delivery
of this Agreement and prior to the date of any Credit  Extension  hereunder,  no
steps have been taken to terminate any Pension Plan under circumstances in which
the Pension Plan has insufficient  assets to pay all its benefit liabilities (as
required  by section  4041(b)(1)  of ERISA),  and no  contribution  failure  has
occurred  with respect to any Pension  Plan,  sufficient  to give rise to a Lien
under section 302(f) of ERISA.  No condition  exists or event or transaction has
occurred  with respect to any Pension Plan which might result in the  incurrence
by the Borrower or any member of the Controlled Group of any material liability,
material  fine or  material  penalty.  Except as  disclosed  in Item 6.11 of the
Disclosure Schedule, neither the Borrower nor any member of the Controlled Group

         threatened

                           (i)  claims,  complaints,  notices  or  requests  for
                  information   received   by  the   Borrower   or  any  of  its
                  Subsidiaries  with  respect to any  alleged  violation  of any
                  Environmental  Law which could  result in a  liability  to the
                  Borrower  or  its   Restricted   Subsidiaries   in  excess  of
                  $1,000,000 individually or in the aggregate, or

                  Borrower  or  its   Restricted   Subsidiaries   in  excess  of
                  $1,000,000 individually or in the aggregate;

         CERCLIS  or on any  similar  state  list or  which  is the  subject  of
         federal,  state or local  enforcement  actions or other  investigations
         which  may  lead  to  material  claims  against  the  Borrower  or such
         Subsidiary  for any  remedial  work,  damage to  natural  resources  or
         personal injury, including claims under CERCLA;

                  (h) there are no polychlorinated biphenyls or friable asbestos

         aggregate,  have,  or could  reasonably be expected to have, a Material
         Adverse Effect; and


                                      -62-
<PAGE>



                  (i) no  conditions  exist at, on or under any  property now or
         previously  owned or leased by the Borrower which,  with the passage of
         time,  or the  giving of notice or both,  would  give rise to  material
         liability under any Environmental Law.

         SECTION 6.13. Accuracy of Information.  None of the factual information
heretofore  or  contemporaneously  furnished  by or on behalf of the Borrower in
writing  to any  Secured  Party  for  purposes  of or in  connection  with  this
Agreement,  or any  transaction  contemplated  hereby  or  with  respect  to any
Permitted  Acquisition or the financing  contemplated  hereby (true and complete
copies of which were  furnished to the Secured  Parties in  connection  with its
execution  and delivery  hereof),  contains  any untrue  statement of a material
fact,  and  none  of  the  other  factual  information  hereafter  furnished  in
connection with this Agreement or any other Loan Document by the Borrower or any
other  Obligor to any  Secured  Party will  contain  any untrue  statement  of a
material  fact on the date as of which such  information  is dated or  certified
and,  as of the date of the  execution  and  delivery of this  Agreement  by the
Administrative  Agent and each Lender,  the  information  delivered prior to the
date of  execution  and  delivery of this  Agreement  (unless  such  information
specifically  relates to a prior  date) does not,  and the  factual  information
hereafter  furnished shall not on the date as of which such information is dated
or certified,  omit to state any material fact necessary to make any information
not misleading.

         SECTION  6.14.  Regulations  U and X.  No  Obligor  is  engaged  in the
business of extending  credit for the purpose of purchasing  or carrying  margin
stock,  and no  proceeds  of any Credit  Extensions  will be used to purchase or
carry  margin  stock or  otherwise  for a purpose  which  violates,  or would be
inconsistent  with, F.R.S. Board Regulation U or X. Terms for which meanings are
provided  in  F.R.S.  Board  Regulation  U or X or any  regulations  substituted
therefor,  as from time to time in effect,  are used in this  Section  with such
meanings.

         SECTION 6.15.  Year 2000  Problem.  Each Obligor has reviewed the areas
within its business and operations which could be adversely affected by, and has
developed  or is  developing a program to address on a timely  basis,  the "Year
2000 Problem" (that is, the risk that computer applications used by such Obligor
may be  unable  to  recognize  and  properly  perform  date-sensitive  functions
involving certain dates prior to and any date after December 31, 1999). Based on
such review and  program,  no Obligor  reasonably  believes  that the "Year 2000
Problem" could reasonably be expected to have a Material Adverse Effect.  At the
request  of  the   Administrative   Agent,   the  Borrower   shall  provide  the
Administrative Agent assurance reasonably acceptable to the Administrative Agent
of the Borrower's Year 2000 compatibility.

         SECTION 6.16. Government  Contracts.  The Borrower is not materially in
default as to the terms of any  government  contract and has received no notices
of  default  or notices  to cure  under any  government  contract  for which the
performance deficiency noted by any Governmental Authority has not been cured or
otherwise resolved to such Governmental Authority's satisfaction.

         SECTION 6.17. No Debarment.  The Borrower is not subject to any pending
or threatened debarment proceedings.


                                      -63-

         SECTION  6.18.  Assignment  of Payments.  The Borrower has the right to
assign to the Administrative  Agent all payments due or to become due under each
of the Borrower's or the Restricted Subsidiary's government contracts, and there
exists no uncancelled  prior  assignment of payments under any of such Persons's
government contracts.


                                   ARTICLE VII

         previous  Fiscal Year and ending  with the end of such Fiscal  Quarter,
         and including (in each case),  in comparative  form the figures for the
         corresponding  Fiscal  Quarter  in,  and year to date  portion  of, the

         covenants  set forth in Section  7.2.4 and stating  that no Default has

cause each of its Subsidiaries to, maintain,  preserve, protect and keep its and
their  respective  properties  in  good  repair,  working  order  and  condition

representatives, at reasonable times and intervals upon reasonable notice to the
Borrower,  to visit its  offices,  to discuss  its  financial  matters  with its

not the  obligation,  to contact the  contracting  officer under any  government
contract  directly to determine the  Borrower's or any  Restricted  Subsidiary's
contract  performance status on the government  contract;  however,  any contact
between the  Administrative  Agent and the contracting  officer shall be made on
reasonable  notice to the Borrower and in the  presence of a  representative  or
representatives  of the Borrower.  At the  Administrative  Agent's request,  the

         the applicable Pledge Agreement, pledge to the Administrative Agent for
         its benefit and that of the Secured  Parties,  all  intercompany  notes

         determined  in good  faith by the  Administrative  Agent in  excess  of
         $2,500,000, such Obligor will execute and deliver to the Administrative
         Agent  a  Mortgage,  together  with,  in the  case  of  real  property,
         mortgagee's title insurance policies in amounts,  in form and substance
         (including, if available, a revolving credit endorsement) and issued by
         insurers  satisfactory to the  Administrative  Agent, and such policies
         shall be accompanied by evidence of the payment in full of all premiums
         thereon.

together,  in each case,  with such  opinions of legal counsel for the Borrower,
which may be the corporate general counsel of the Borrower, (which shall be from
counsel satisfactory to the Administrative Agent) relating thereto,  which legal

Subsidiary,  then the provisions of clause (a) of this Section shall  thereafter
apply to any Foreign  Subsidiary  and/or (as the case may be) the  provisions of

other  Affiliates,  unless  such  arrangement  or  contract  (i) is on fair  and
reasonable terms no less favorable to the Borrower or such Restricted Subsidiary

term) referring to the  Obligations;  or the Borrower or any of its Subsidiaries
shall,  directly  or  indirectly,  disavow  or  contest  in any  manner  (i) the
effectiveness,   validity  or   enforceability   of  any  of  the  Subordination
Provisions,  (ii) that the Subordination Provisions exist for the benefit of the
Administrative  Agent, the Lenders and the Issuers or (iii) that all payments of
principal of or premium and interest on the Subordinated  Debt, or realized from
the liquidation of any property of any Obligor,  shall be subject to any of such
Subordination Provisions.

expressly  waived by the  Borrower)  and the Borrower or any other Obligor shall
automatically  and  immediately be obligated to deposit with the  Administrative
Agent cash collateral in an amount equal to all Letter of Credit Outstandings.

(other than any Event of Default described in clauses (a) through (d) of Section

shall be and become  immediately due and payable,  without further  presentment,
protest,  notice or  demand  (all of which are  hereby  expressly  waived by the
Borrower)  and/or,  as the case may be, the Commitments  shall terminate and the

                                   ARTICLE IX

                                THE CREDIT AGENTS

         SECTION 9.1. Actions. Each Lender hereby appoints (a) Scotiabank as its
Administrative  Agent and  Imperial  as its  Documentation  Agent  under and for
purposes  of this  Agreement,  the Notes and each other Loan  Document,  and (b)
Scotiabank as its Agent (as defined in the Collateral  Documents)  under and for
purposes of the Collateral  Documents.  Each Lender authorizes the Credit Agents
to act on behalf of such Lender under this  Agreement,  the Notes and each other
Loan  Document  and,  in the  absence  of other  written  instructions  from the
Required  Lenders  received from time to time by the Credit Agents (with respect
to which the Credit  Agents  agree that they will  comply,  except as  otherwise
provided in this  Section or as  otherwise  advised by counsel in order to avoid
contravention  of  applicable  law),  to  exercise  such  powers  hereunder  and
thereunder as are specifically  delegated to or required of the Credit Agents by
the terms hereof and  thereof,  together  with such powers as may be  reasonably
incidental  thereto.  Each Lender  hereby  indemnifies  (which  indemnity  shall
survive any termination of this Agreement) the Credit Agents, pro rata according
to such Lender's  Total  Percentage,  from and against any and all  liabilities,
obligations,  losses,  damages,  claims, costs or expenses of any kind or nature
whatsoever  which  may at any time be  imposed  on,  incurred  by,  or  asserted
against,  the  Credit  Agents  in any way  relating  to or  arising  out of this
Agreement,  the  Notes  and  any  other  Loan  Document,   including  reasonable
attorneys'  fees,  and as to which the Credit  Agents are not  reimbursed by the
Borrower;  provided,  however, that no Lender shall be liable for the payment of
any portion of such liabilities,  obligations, losses, damages, claims, costs or
expenses  which are determined by a court of competent  jurisdiction  in a final
proceeding to have resulted from the Credit  Agents' gross  negligence or wilful
misconduct. The Credit Agents shall not be required to take any action hereunder
or under any other Loan Document,  or to prosecute or defend any suit in respect
of this  Agreement  or any other  Loan  Document,  unless  they are  indemnified
hereunder to their satisfaction.  If any indemnity in favor of the Credit Agents
shall be or become, in the Credit Agents' determination,  inadequate, the Credit
Agents may call for additional  indemnification from the Lenders and cease to do
the acts indemnified against hereunder until such additional indemnity is given.

         SECTION 9.2. Funding  Reliance,  etc. Unless the  Administrative  Agent
shall have been  notified by telephone,  confirmed in writing,  by any Lender by
3:00 p.m.,  New York time,  on the Business  Day prior to a Borrowing  that such
Lender will not make available the amount which would  constitute its Percentage
of such Borrowing on the date specified therefor,  the Administrative  Agent may
assume  that such Lender has made such amount  available  to the  Administrative
Agent and, in reliance upon such  assumption,  make  available to the Borrower a
corresponding  amount. If and to the extent that such Lender shall not have made
such amount available to the Administrative  Agent, such Lender and the Borrower
severally  agree to repay the  Administrative  Agent  forthwith  on demand  such
corresponding  amount together with interest thereon, for each day from the date
the Administrative  Agent made such amount available to the Borrower to the date
such  amount  is  repaid  to the  Administrative  Agent,  at the  interest  rate
applicable at the time to Loans  comprising  such  Borrowing (in the case of the
Borrower)  and (in the case of a  Lender),  at the  Federal  Funds Rate (for the
first two Business Days after which such

                                      -83-
<PAGE>



amount has not been repaid,  and  thereafter at the interest rate  applicable to
Loans comprising such Borrowing.

         SECTION 9.3.  Exculpation.  Neither the Credit  Agents nor any of their
directors,  officers,  employees or agents shall be liable to any Lender for any
action  taken or omitted to be taken by them under this  Agreement  or any other
Loan  Document,  or in connection  herewith or  therewith,  except for their own
wilful  misconduct  or gross  negligence,  nor  responsible  for any recitals or
warranties  herein  or  therein,  nor  for  the  effectiveness,  enforceability,
validity or due execution of this Agreement or any other Loan Document,  nor for
the creation, perfection or priority of any Liens purported to be created by any
of the Loan Documents, or the validity, genuineness, enforceability,  existence,
value  or  sufficiency  of any  collateral  security,  nor to make  any  inquiry
respecting the performance by the Borrower of its obligations hereunder or under
any other Loan Document. Any such inquiry which may be made by the Credit Agents
shall not  obligate  it to make any further  inquiry or to take any action.  The
Credit Agents shall be entitled to rely upon advice of counsel  concerning legal
matters and upon any notice,  consent,  certificate,  statement or writing which
the Credit Agents  believe to be genuine and to have been  presented by a proper
Person.

         SECTION 9.4. Successor. Either of the Credit Agents may resign from its
agency  position at any time upon at least 30 days' prior notice to the Borrower
and all Lenders.  If either of the Credit Agents at any time shall  resign,  the
Required  Lenders  may,  upon at least 3 days' (so long as one of such days is a
Business  Day) prior notice to the Borrower  and all  Lenders,  appoint  another
Lender as a successor  Administrative  Agent,  Documentation Agent, or Agent, as
appropriate,   which   shall   thereupon   become  the   Administrative   Agent,
Documentation  Agent  or  Agent,  as  appropriate,  hereunder.  If no  successor
Administrative Agent,  Documentation Agent or Agent, as appropriate,  shall have
been so  appointed  by the  Required  Lenders,  and  shall  have  accepted  such
appointment,  within 30 days after the retiring  Credit Agent's giving notice of
resignation,  then the retiring Credit Agent may, on behalf of the Lenders, upon
at least 3 days'  prior  notice  to the  Borrower  and all  Lenders,  appoint  a
successor  Administrative  Agent,  Documentation Agent or Agent, as appropriate,
which shall be one of the Lenders or a commercial banking institution  organized
under the laws of the U.S. (or any State thereof) or a U.S.  branch or agency of
a commercial banking institution,  and having (x) a combined capital and surplus
of at least $250,000,000 and (y) a credit rating of AA or better by Moody's or a
comparable  rating by S&P;  provided,  however,  that if,  after  expending  all
reasonable  commercial  efforts,  such retiring Credit Agent is unable to find a
commercial  banking  institution which is willing to accept such appointment and
which  meets the  qualifications  set forth in clause (y) above,  such  retiring
Credit Agent,  shall be permitted to appoint as its successor from all available
commercial  banking   institutions  willing  to  accept  such  appointment  such
institution  having the highest  credit rating of all such available and willing
institutions.  Upon the  acceptance  of any  appointment  as such  Credit  Agent
hereunder by a successor  Credit  Agent,  such  successor  Credit Agent shall be
entitled to receive  from the retiring  Credit Agent such  documents of transfer
and assignment as such successor Credit Agent may reasonably request,  and shall
thereupon succeed to and become vested with all rights,  powers,  privileges and
duties of the retiring  Credit  Agent,  and the  retiring  Credit Agent shall be
discharged from its duties and

                                      -84-
<PAGE>



obligations under this Agreement.  After any retiring Credit Agent's resignation
hereunder as the Credit Agent, the provisions of

                  (a) this  Article  IX shall  inure  to its  benefit  as to any
         actions  taken or omitted to be taken by it while it was a Credit Agent
         under this Agreement; and

                  (b) Section 10.3 and Section  10.4 shall  continue to inure to
         its benefit.


         SECTION 9.5.  Credit  Extensions  by Scotiabank  and Imperial.  Each of
Scotiabank  and  Imperial  shall have the same rights and powers with respect to
(x) the Credit Extensions made by it or any of its Affiliates, and (y) the Notes
held by it or any of its  Affiliates  as any other  Lender and may  exercise the
same as if it were not a Credit Agent.  Such Credit Agent and its Affiliates may
accept  deposits  from,  lend  money  to,  and  generally  engage in any kind of
business with the Borrower or any  Subsidiary or Affiliate of the Borrower as if
Scotiabank or Imperial, as appropriate were not a Credit Agent hereunder.

         SECTION 9.6. Credit  Decisions.  Each Lender  acknowledges that it has,
independently  of the Credit  Agents and each  other  Lender,  and based on such
Lender's  review of the financial  information of the Borrower,  this Agreement,
the other Loan Documents  (the terms and provisions of which being  satisfactory
to such Lender) and such other documents, information and investigations as such
Lender  has  deemed  appropriate,  made its own  credit  decision  to extend its
Commitments.  Each Lender also acknowledges  that it will,  independently of the
Credit  Agents  and  each  other  Lender,  and  based on such  other  documents,
information  and  investigations  as it  shall  deem  appropriate  at any  time,
continue to make its own credit  decisions as to  exercising  or not  exercising
from time to time any rights and privileges available to it under this Agreement
or any other Loan Document.

         SECTION 9.7. Copies, etc. Each Credit Agent shall give prompt notice to
each Lender of each notice or request  required or permitted to be given to such
Credit Agent by the  Borrower  pursuant to the terms of this  Agreement  (unless
concurrently  delivered to the Lenders by the Borrower).  Such Credit Agent will
distribute to each Lender each  document or instrument  received for its account
and copies of all other  communications  received by such Credit  Agent from the
Borrower for distribution to the Lenders by such Credit Agent in accordance with
the terms of this Agreement or any other Loan Document.

Agreement  and of each other  Loan  Document  may from time to time be  amended,

                  (a)  extend any  Commitment  Termination  Date or modify  this
         Section 10.1 without the consent of all Lenders;

                  (b) increase the aggregate  amount of any Lender's  Percentage
         of any Commitment  Amount,  increase the aggregate  amount of any Loans
         required to be made by a Lender  pursuant to its  Commitments or reduce
         any fees  described  in Article III  payable to any Lender  without the
         consent of such Lender;

                  (c) extend the Stated  Maturity Date for any Lender's Loan, or
         reduce the principal amount of or rate of interest on any Lender's Loan
         or extend the date on which  interest or fees are payable in respect of
         such Lender's Loans,  in each case,  without the consent of such Lender
         (it being understood and agreed,  however, that any vote to rescind any
         acceleration  made  pursuant  to Section 8.2 and Section 8.3 of amounts
         owing  with  respect  to the  Loans and other  Obligations  shall  only
         require the vote of the Required Lenders);

                  (d)  change  the  definition  of  "Required  Lenders"  or  any
         requirement  hereunder  that  any  particular  action  be  taken by all
         Lenders without the consent of all Lenders;

                  (e) increase the Stated  Amount of any Letter of Credit unless
         consented to by the Issuer of such Letter of Credit;

                  (f) release (i) any  Guarantor  from its  obligations  under a
         Guaranty or (ii) all or  substantially  all of the collateral under the
         Loan  Documents,  in either case  without the consent of all Lenders as
         expressly provided herein or therein;

                  (g) change any of the terms of clause (d) of Section  2.1.4 or
         Section 2.3.2 without the consent of Scotiabank; or

                  (h) affect  adversely the interests,  rights or obligations of
         the Administrative Agent (in its capacity as the Administrative Agent),
         or any Issuer (in its capacity as Issuer),  unless  consented to by the
         Administrative Agent or such Issuer, as the case may be.

No failure or delay on the part of the  Administrative  Agent, any Issuer or any
Lender in exercising  any power or right under this  Agreement or any other Loan
Document  shall  operate  as a waiver  thereof,  nor shall any single or partial
exercise  of any such  power or right  preclude  any other or  further  exercise
thereof or the  exercise of any other power or right.  No notice to or demand on
the Borrower or any other  Obligor in any case shall entitle it to any notice or
demand  in  similar  or  other  circumstances.  No  waiver  or  approval  by the
Administrative Agent, any Issuer or any Lender under this Agreement or any other
Loan  Document  shall,  except  as may be  otherwise  stated  in such  waiver or
approval,  be  applicable  to  subsequent  transactions.  No waiver or  approval
hereunder shall require any similar or dissimilar waiver or approval  thereafter
to be granted hereunder.

                  (a) (i) the  syndication  efforts  of  Scotiabank  and any due

         Document  and/or  any  Uniform  Commercial  Code  financing  statements
         relating  thereto  and  all  amendments,  supplements,  amendments  and

and legal  expenses of counsel to each  Secured  Party  incurred by such Secured
Party in connection with (x) the negotiation of any  restructuring or "work-out"

enforcement of any Obligations.

delivery  of  this  Agreement  by  each  Secured  Party,   the  Borrower  hereby
indemnifies,  exonerates  and  holds  each  Secured  Party  and  each  of  their
respective  officers,  directors,   employees  and  agents  (collectively,   the
"Indemnified  Parties")  free and harmless from and against any and all actions,
causes of action,  suits, losses,  costs,  liabilities and damages, and expenses
incurred in connection  therewith  (irrespective of whether any such Indemnified
Party is a party to the action for which  indemnification  hereunder is sought),
including  reasonable  attorneys' fees and  disbursements,  whether  incurred in
connection  with  actions  between or among the  parties  hereto or the  parties
hereto and third parties (collectively, the "Indemnified Liabilities"), incurred
by the Indemnified  Parties or any of them as a result of, or arising out of, or
relating to

                  (a) any transaction  financed or to be financed in whole or in
         part,  directly  or  indirectly,   with  the  proceeds  of  any  Credit
         Extension,  including all Indemnified Liabilities arising in connection
         with transactions  contemplated hereby or by any other Loan Document or
         transactions  which are financed with proceeds of any Loan or which are
         supported by any Letter of Credit;

                  (b) the entering into and  performance  of this  Agreement and
         any other Loan Document by any of the  Indemnified  Parties  (including
         any action brought by or on behalf of the Borrower as the result of any
         determination by the Required Lenders pursuant to Article V not to fund
         any Credit  Extension),  provided  that any such  action is resolved in
         favor of such Indemnified Party;

                  (c) any investigation, litigation or proceeding related to any
         acquisition  or  proposed  acquisition  by the  Borrower  or any of its
         Subsidiaries  of all or any  portion  of the  stock  or  assets  of any
         Person, whether or not an Indemnified Party is party thereto;

                  (d) any investigation, litigation or proceeding related to any
         environmental  cleanup,  audit,  compliance or other matter relating to
         the protection of the environment or the Release by the Borrower or any
         of its Subsidiaries of any Hazardous Material;

                  (e) the presence on or under, or the escape, seepage, leakage,
         spillage, discharge,  emission,  discharging or releases from, any real
         property owned or operated by the Borrower or any Subsidiary thereof of
         any Hazardous  Material  (including any losses,  liabilities,  damages,
         injuries,  costs,  expenses  or claims  asserted  or arising  under any
         Environmental  Law),  regardless  of  whether  caused by, or within the
         control of, the Borrower or such Subsidiary; or

                  (f) each Lender's Environmental Liability (the indemnification
         herein  shall  survive  repayment  of the Notes and any transfer of the
         property of the Borrower or any of its  Subsidiaries  by foreclosure or
         by a deed  in  lieu  of  foreclosure  for  any  Lender's  Environmental
         Liability,  regardless of whether  caused by, or within the control of,
         the Borrower or such Subsidiary);


                                      -88-
<PAGE>



except  for any  such  Indemnified  Liabilities  arising  for the  account  of a
particular Indemnified Party by reason of the relevant Indemnified Party's gross
negligence or wilful  misconduct.  The Borrower and its  successors  and assigns
hereby waive, release and agree not to make any claim or bring any cost recovery
action against,  any Secured Party under CERCLA or any state equivalent,  or any
similar law now existing or hereafter  enacted.  It is expressly  understood and
agreed that to the extent that any of such Persons is strictly  liable under any
Environmental  Laws,  the  Borrower's  obligation  to  such  Person  under  this
indemnity  shall likewise be without regard to fault on the part of the Borrower
with respect to the  violation or condition  which  results in liability of such
Person. If and to the extent that the foregoing undertaking may be unenforceable
for any reason,  the Borrower hereby agrees to make the maximum  contribution to
the payment and  satisfaction  of each of the Indemnified  Liabilities  which is
permissible under applicable law.

         SECTION 10.5. Survival.  The obligations of the Borrower under Sections
4.3,  4.4, 4.5, 4.6,  10.3 and 10.4,  and the  obligations  of the Lenders under
Section  9.1,  shall in each case  survive  any  assignment  from one  Lender to
another  (in the case of  Sections  10.3 and 10.4) and any  termination  of this
Agreement, the payment in full of all the Obligations and the termination of all
the  Commitments.  The  representations  and warranties made by the Borrower and
each other  Obligor in this  Agreement  and in each  other Loan  Document  shall
survive the  execution  and delivery of this  Agreement and each such other Loan
Document.  The Fee Letter  shall,  upon the  Effective  Date,  supercede  in all
respects,  the Fee Letter  dated as of June 8, 1998  between  the  Borrower  and
Scotiabank.

         SECTION  10.6.  Severability.  Any  provision of this  Agreement or any
other Loan Document  which is prohibited or  unenforceable  in any  jurisdiction
shall, as to such provision and such jurisdiction,  be ineffective to the extent
of such  prohibition  or  unenforceability  without  invalidating  the remaining
provisions of this  Agreement or such Loan Document or affecting the validity or
enforceability of such provision in any other jurisdiction.

         SECTION 10.7.  Headings.  The various headings of this Agreement and of
each other Loan Document are inserted for convenience  only and shall not affect
the meaning or  interpretation  of this Agreement or such other Loan Document or
any provisions hereof or thereof.

         SECTION  10.8.  Execution in  Counterparts,  Effectiveness,  etc.  This
Agreement may be executed by the parties hereto in several counterparts, each of
which shall be an original  and all of which shall  constitute  together but one
and the same agreement.  This Agreement shall become effective when counterparts
hereof  executed on behalf of the Borrower,  the  Administrative  Agent and each
Lender (or notice thereof  satisfactory to the Administrative  Agent) shall have
been  received by the  Administrative  Agent and notice  thereof shall have been
given by the Administrative Agent to the Borrower and each Lender.

         SECTION 10.9.  Governing Law; Entire Agreement.  THIS AGREEMENT, THE
NOTES AND EACH OTHER LOAN DOCUMENT (INCLUDING PROVISIONS WITH
RESPECT TO INTEREST, LOAN CHARGES AND COMMITMENT FEES) SHALL

                                      -89-

EACH BE DEEMED TO BE A CONTRACT  MADE UNDER AND GOVERNED BY THE INTERNAL LAWS OF
THE STATE OF NEW YORK (INCLUDING FOR SUCH PURPOSE  SECTIONS 5-1401 AND 5-1402 OF
THE GENERAL OBLIGATIONS LAW OF THE STATE OF NEW YORK), EXCEPT TO THE EXTENT THAT
THE VALIDITY OR  PERFECTION  OF A SECURITY  INTEREST OR MORTGAGE  HEREUNDER,  OR
REMEDIES HEREUNDER,  IN RESPECT OF ANY PARTICULAR COLLATERAL ARE GOVERNED BY THE
LAWS OF A JURISDICTION OTHER THAN THE STATE OF NEW YORK.

This  Agreement,  the  Notes,  the  other  Loan  Documents  and the  Fee  Letter
constitute the entire understanding among the parties hereto with respect to the
subject matter hereof and thereof and supersede any prior agreements, written or
oral, with respect thereto;  provided,  however,  that all provisions  regarding
indemnification  and  expenses  in  the  Existing  Credit  Agreement  including,
Sections  3.3,  10.3  and 10.4  thereunder,  shall  survive  the  amendment  and
restatement of the Existing  Credit  Agreement and shall continue and be binding
on the parties hereto.

         SECTION 10.10.  Successors and Assigns. This Agreement shall be binding
upon and shall inure to the benefit of the parties  hereto and their  respective
successors and assigns; provided, however, that:

                  (a) the  Borrower  may not  assign or  transfer  its rights or
         obligations   hereunder  without  the  prior  written  consent  of  the
         Administrative Agent and all Lenders; and

                  (b) the rights of sale, assignment and transfer of the Lenders
         are subject to Section 10.11.

         SECTION 10.11. Sale and Transfer of Loans and Notes;  Participations in
Loans and Notes. Each Lender may assign, or sell  participations  in, its Loans,
Letters of Credit and  Commitments  to one or more other  Persons in  accordance
with this Section 10.11.

         SECTION 10.11.1.  Assignments.  Any Lender,

                  (a) with the consent of the  Borrower  and the  Administrative
         Agent (which  consents  shall not be  unreasonably  delayed or withheld
         and, which consent, in the case of the Borrower,  shall not be required
         during the  continuation of an Event of Default) may at any time assign
         and  delegate  to  one  or  more  commercial  banks;   other  financial
         institutions;  special-purpose investment funds which are organized for
         the  specific  purpose  of  making,   acquiring  participations  in  or
         investing  in loans of the type made  pursuant to this  Agreement;  and
         funds that typically invest in bank loans, and

                  (b) upon notice to the Borrower and the Administrative  Agent,
         may assign and delegate to any of its  Affiliates,  any other Lender or
         an Approved Fund

(each Person described in either of the foregoing clauses as being the Person to
whom such assignment and delegation is to be made, being hereinafter referred to
as an  "Assignee  Lender"),  all or any fraction of such  Lender's  total Loans,
Letter of Credit Outstandings and Commitments

                                      -90-
<PAGE>



in a minimum  aggregate  amount of $5,000,000  if such  assignment is to a party
other than an Affiliate or another  Lender,  a fund or an Approved  Fund (or, if
less,  the entire  remaining  amount of such  Lender's  Loans,  Letter of Credit
Outstandings and Commitments).  Each Obligor and the Administrative  Agent shall
be entitled to continue to deal solely and directly  with a Lender in connection
with the interests so assigned and delegated to an Assignee Lender until

                  (c) notice of such  assignment and  delegation,  together with
         (i) payment  instructions,  (ii) the Internal  Revenue Service Forms or
         other statements  contemplated or required to be delivered  pursuant to
         Section 4.6, if applicable, and (iii) addresses and related information
         with respect to such Assignee Lender,  shall have been delivered to the
         Borrower and the Administrative  Agent by such assignor Lender and such
         Assignee Lender;

                  (d) such Assignee  Lender shall have executed and delivered to
         the  Borrower  and  the   Administrative   Agent  a  Lender  Assignment
         Agreement, accepted by the Administrative Agent; and

                  (e) the processing fees described below shall have been paid.

From and  after the date  that the  Administrative  Agent  accepts  such  Lender
Assignment  Agreement,  (x) the  Assignee  Lender  thereunder  shall  be  deemed
automatically  to have  become a party  hereto and to the extent that rights and
obligations  hereunder have been assigned and delegated to such Assignee  Lender
in connection with such Lender Assignment  Agreement,  shall have the rights and
obligations of a Lender  hereunder and under the other Loan  Documents,  and (y)
the assignor  Lender,  to the extent that rights and obligations  hereunder have
been  assigned and  delegated by it in  connection  with such Lender  Assignment
Agreement,  shall be released from its obligations hereunder and under the other
Loan  Documents.  Within five Business Days after its receipt of notice that the
Administrative  Agent has received and  accepted an executed  Lender  Assignment
Agreement (and if requested by the Assignee Lender),  but subject to clause (c),
the Borrower shall execute and deliver to the Administrative Agent (for delivery
to the relevant  Assignee  Lender) a new Note evidencing such Assignee  Lender's
assigned Loans and  Commitments  and, if the assignor  Lender has retained Loans
and Commitments  hereunder (and if requested by such Lender), a replacement Note
in the principal  amount of the Loans and  Commitments  retained by the assignor
Lender  hereunder  (such Note to be in exchange  for, but not in payment of, the
Note then held by such assignor Lender).  Each such Note shall be dated the date
of the predecessor  Note. The assignor Lender shall mark each  predecessor  Note
"exchanged" and deliver each of them to the Borrower.  Accrued  interest on that
part of each  predecessor  Note evidenced by a new Note, and accrued fees, shall
be paid as provided in the Lender Assignment Agreement. Accrued interest on that
part of each  predecessor  Note evidenced by a replacement Note shall be paid to
the assignor Lender. Accrued interest and accrued fees shall be paid at the same
time or times  provided  in the  predecessor  Note and in this  Agreement.  Such
assignor  Lender or such Assignee  Lender must also pay a processing  fee in the
amount  of  $3,500 to the  Administrative  Agent  upon  delivery  of any  Lender
Assignment Agreement unless such Assignee Lender is another Lender, an Affiliate
of such assignor Lender or an Approved Fund.  Notwithstanding  any other term of
this Section, the agreement of

                                      -91-
<PAGE>



Scotiabank  to  provide  the Swing  Line  Loan  Commitment  shall not  impair or
otherwise  restrict  in any  manner  the  ability  of  Scotiabank  to  make  any
assignment  of its Loans or  Commitments,  it being  understood  and agreed that
Scotiabank may terminate its Swing Line Loan  Commitment,  either in whole or in
part,  in connection  with the making of any  assignment so long as the assignee
has agreed to assume the Swing Line Loan  Commitment.  Any attempted  assignment
and  delegation not made in accordance  with this Section  10.11.1 shall be null
and void.  Notwithstanding  anything to the contrary  set forth  above,  (i) any
Lender may (without requesting the consent of the Borrower or the Administrative
Agent) pledge its Loans to a Federal  Reserve Bank in support of borrowings made
by such Lender from such  Federal  Reserve  Bank,  and (ii) any Lender that is a
fund that  invests in bank loans may (without the consent of the Borrower or the
Administrative Agent) pledge all or any portion of its rights in connection with
this Agreement to holders of  obligations  owed, or securities  issued,  by such
fund as security for such  obligations or securities,  or to the trustee for, or
other representative of, such holders,  provided,  that any foreclosure or other
exercise  of  remedies  by such  holder  or  trustee  shall  be  subject  to the
provisions of this Section  regarding  assignments  in all  respects.  No pledge
described in the  immediately  preceding  clause (ii) shall  release such Lender
from its obligations hereunder.

                  (f) In the event that S&P or  Moody's,  shall,  after the date
         that any Person becomes a Lender,  downgrade the long-term  certificate
         of deposit ratings of such Lender,  and the resulting  ratings shall be
         below BBB- or Baa3, respectively, or the equivalent, then the Borrower,
         the Swingline Lender and each Issuer shall each have the right, but not
         the  obligation,  upon  notice to such  Lender  and the  Administrative
         Agent, to replace such Lender with a Replacement  Lender  acceptable to
         the  Borrower  and the  Administrative  Agent (such  consents not to be
         unreasonably withheld or delayed;  provided, that no such consent shall
         be required if the Replacement Lender is an existing Lender),  and upon
         any such downgrading of any Lender's  long-term  certificate of deposit
         rating,  each such  Lender  hereby  agrees to  transfer  and assign (in
         accordance with Section 10.11.1) all of its Commitments,  Loans,  Notes
         and other rights and  obligations  under this  Agreement  and all other
         Loan   Documents   (including   Reimbursement   Obligations)   to  such
         Replacement Lender;  provided,  however, that (i) such assignment shall
         be without  recourse,  representation or warranty (other than that such
         Lender owns the Commitments,  Loans and Notes being assigned,  free and
         clear of any Liens) and (ii) the purchase price paid by the Replacement
         Lender shall be in the amount of such Lender's Loans and its Percentage
         of outstanding Reimbursement Obligations, together with all accrued and
         unpaid  interest and fees in respect  thereof,  plus all other  amounts
         (other  than the  amounts  (if any)  demanded  and  unreimbursed  under
         Sections 4.2, 4.3, 4.5 and 4.6,  which shall be paid by the  Borrower),
         owing  to  such  Lender   hereunder.   Upon  any  such  termination  or
         assignment,  such  Lender  shall  cease to be a party  hereto but shall
         continue  to be  entitled to the  benefits  of any  provisions  of this
         Agreement  which  by  their  terms  survive  the  termination  of  this
         Agreement.

                  (g) Upon  receipt  by the  Borrower  of the  predecessor  Note
         marked  "canceled",  the  Borrower  shall issue a  replacement  Note or
         Notes,  as the  case  may  be,  to such  Replacement  Lender  and  such
         institution  shall  become  a  "Lender"  for all  purposes  under  this
         Agreement and the other Loan Documents.

The  Borrower  hereby  designates  the  Administrative  Agent  to  serve  as the
Borrower's agent, solely for the purpose of this Section, to maintain a register
(the  "Register")  on which the  Administrative  Agent will record each Lender's
Commitment,  the Loans made by each Lender and the Notes  evidencing such Loans,
and each  repayment  in  respect  of the  principal  amount of the Loans of each
Lender and annexed to which the Administrative Agent shall retain a copy of each
Lender Assignment  Agreement  delivered to the Administrative  Agent pursuant to
this Section. Failure to make any recordation, or any error in such recordation,
shall not affect the Borrower's or any other Obligor's Obligations in respect of
such Loans or Notes.  The entries in the Register  shall be  conclusive,  in the
absence of manifest error, and the Borrower,  the  Administrative  Agent and the
Lenders  shall  treat  each  Person  in whose  name a Loan and  related  Note is
registered   as  the  owner   thereof  for  all  purposes  of  this   Agreement,
notwithstanding  notice or any  provision  herein to the  contrary.  A  Lender's
Commitment  and the Loans made pursuant  thereto and the Notes  evidencing  such
Loans  may be  assigned  or  otherwise  transferred  in whole or in part only by
registration of such  assignment or transfer in the Register.  Any assignment or
transfer  of a Lender's  Commitment  or the Loans or the Notes  evidencing  such
Loans made  pursuant  thereto  shall be  registered  in the  Register  only upon
delivery  to the  Administrative  Agent of a Lender  Assignment  Agreement  duly
executed  by the  assignor  thereof.  No  assignment  or  transfer of a Lender's
Commitment or the Loans made pursuant thereto or the Notes evidencing such Loans
shall be effective  unless such  assignment or transfer shall have been recorded
in the Register by the Administrative Agent as provided in this Section.

         SECTION  10.11.2.  Participations.  Any  Lender may sell to one or more
commercial  banks,  financial  institutions,  any of its Affiliates,  a fund, an
Approved  Fund or  another  Lender  (each of such  commercial  banks,  financial
institutions, any of its Affiliates, a fund, an Approved Fund and another Lender
being  herein  called a  "Participant")  participating  interests  in any of the
Loans,  Commitments,  or other  interests  of such Lender  hereunder;  provided,
however, that

                  (a) no participation  contemplated in this Section 10.11 shall
         relieve  such  Lender  from its  Commitments  or its other  obligations
         hereunder or under any other Loan Document;

                  (b)  such  Lender  shall  remain  solely  responsible  for the
         performance of its Commitments and such other obligations;

                  (c) the Borrower and each other Obligor and the Administrative
         Agent shall  continue to deal solely and  directly  with such Lender in
         connection  with  such  Lender's  rights  and  obligations  under  this
         Agreement and each of the other Loan Documents;

                  (d) no Participant, unless such Participant is an Affiliate of
         such Lender or is itself a Lender,  shall be  entitled to require  such
         Lender to take or refrain from taking any action hereunder or under any
         other  Loan  Document,  except  that such  Lender  may  agree  with any
         Participant  that such  Lender  will not,  without  such  Participant's
         consent, take any actions of the type described in clause (a), (b), (f)
         or, to the extent  requiring the consent of each Lender,  clause (c) of
         Section 10.1; and


                                      -93-

                  (e) the Borrower shall not be required to pay any amount under
         this Agreement that is greater than the amount which it would have been
         required to pay had no participating interest been sold.

The  Borrower  acknowledges  and agrees that each  Participant,  for purposes of
Sections 4.3, 4.4, 4.5, 4.6, 4.8, 4.9, 7.1.1, 10.3 and 10.4, shall be considered
a Lender.  Each  Participant  shall  only be  indemnified  for  increased  costs
pursuant to Section  4.3,  4.5 or 4.6 if and to the extent that the Lender which
sold such participating interest to such Participant concurrently is entitled to
make,  and does make,  a claim on the  Borrower for such  increased  costs.  Any
Lender  that sells a  participating  interest in any Loan,  Commitment  or other
interest to a Participant  under this Section  10.11.2 shall  indemnify and hold
harmless the Borrower and the  Administrative  Agent from and against any taxes,
penalties,  interest or other costs or losses (including  reasonable  attorneys'
fees and  expenses)  incurred or payable by the  Borrower or the  Administrative
Agent as a result of the failure of the Borrower or the Administrative  Agent to
comply with its  obligations  to deduct or withhold  any Taxes from any payments
made pursuant to this Agreement to such Lender or the  Administrative  Agent, as
the case may be,  which  Taxes  would not have been  incurred or payable if such
Participant  had been a  Non-U.S.  Lender  that was  entitled  to deliver to the
Borrower, the Administrative Agent or such Lender, and did in fact so deliver, a
duly  completed  and valid  Form  1001 or 4224 (or  applicable  successor  form)
entitling  such  Participant to receive  payments  under this Agreement  without
deduction or withholding of any United States federal taxes.

         SECTION  10.12.  Other  Transactions.  Nothing  contained  herein shall
preclude the Administrative  Agent, any Issuer or any other Lender from engaging
in any transaction,  in addition to those  contemplated by this Agreement or any
other Loan  Document,  with the Borrower or any of its  Affiliates  in which the
Borrower or such Affiliate is not restricted hereby from engaging with any other
Person.

         SECTION 10.13.  Confidentiality.  The Administrative  Agent, the Issuer
and the Lenders shall hold all non-public information (which has been identified
as such by the  Borrower  or any of its  Subsidiaries)  provided  to them by the
Borrower  or any of its  Subsidiaries  pursuant  to or in  connection  with this
Agreement  in  accordance   with  their   customary   procedures   for  handling
confidential information of this nature, but may make disclosure to any of their
examiners,   regulators   (including  the  National   Association  of  Insurance
Commissioners),  Affiliates,  outside auditors,  counsel and other  professional
advisors in  connection  with this  Agreement  or any other Loan  Document or as
reasonably  required  by any  potential  bona fide  transferee,  participant  or
assignee,  or in connection with the exercise of remedies under a Loan Document,
or as requested by any governmental agency or representative thereof or pursuant
to legal process;  provided,  however,  that unless  specifically  prohibited by
applicable law or court order,  the  Administrative  Agent,  the Issuer and each
Lender shall  promptly  notify the  Borrower of any request by any  governmental
agency or representative thereof (other than any such request in connection with
an  examination  of the financial  condition of the  Administrative  Agent,  the
Issuer or such Lender by such  governmental  agency) for  disclosure of any such
non-public  information  and,  where  practicable,  prior to  disclosure of such
information;  prior to any such disclosure  pursuant to this Section 10.13,  the
Administrative Agent, the Issuer and each Lender shall require any such bona

                                      -94-
<PAGE>



fide transferee,  participant and assignee  receiving a disclosure of non-public
information to agree, for the benefit of the Borrower and its  Subsidiaries,  in
writing to be bound by this Section 10.13; and to require such Person to require
any other Person to whom such Person discloses such non-public information to be
similarly bound by this Section 10.13; and except as may be required by an order
of a court of competent  jurisdiction  and to the extent set forth  therein,  no
Lender shall be obligated or required to return any  materials  furnished by the
Borrower or any of its Subsidiaries.

         SECTION  10.14.  Forum  Selection  and  Consent  to  Jurisdiction.  ANY
LITIGATION  BASED HEREON,  OR ARISING OUT OF, UNDER, OR IN CONNECTION WITH, THIS
AGREEMENT  OR ANY OTHER  LOAN  DOCUMENT,  OR ANY  COURSE OF  CONDUCT,  COURSE OF
DEALING,  STATEMENTS  (WHETHER ORAL OR WRITTEN) OR ACTIONS OF THE ADMINISTRATIVE
AGENT,  THE  LENDERS,  ANY ISSUER OR THE  BORROWER  IN  CONNECTION  HEREWITH  OR
THEREWITH SHALL BE BROUGHT AND MAINTAINED EXCLUSIVELY IN THE COURTS OF THE STATE
OF NEW YORK OR IN THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN  DISTRICT OF
NEW YORK;  PROVIDED,  HOWEVER,  THAT ANY SUIT  SEEKING  ENFORCEMENT  AGAINST ANY
COLLATERAL  OR OTHER  PROPERTY  MAY BE BROUGHT,  AT THE  ADMINISTRATIVE  AGENT'S
OPTION,  IN THE  COURTS  OF ANY  JURISDICTION  WHERE  SUCH  COLLATERAL  OR OTHER
PROPERTY  MAY BE FOUND.  THE  BORROWER  HEREBY  IRREVOCABLY  APPOINTS CSC UNITED
STATES  CORPORATION  COMPANY (THE "PROCESS  AGENT"),  WITH AN OFFICE ON THE DATE
HEREOF AT 375 HUDSON STREET,  NEW YORK, NEW YORK 10014, AS ITS AGENT TO RECEIVE,
ON ITS BEHALF AND ON BEHALF OF ITS  PROPERTY,  SERVICE OF COPIES OF THE  SUMMONS
AND  COMPLAINT  AND ANY OTHER  PROCESS WHICH MAY BE SERVED IN ANY SUCH ACTION OR
PROCEEDING.  SUCH  SERVICE MAY BE MADE BY MAILING OR  DELIVERING  A COPY OF SUCH
PROCESS TO THE  BORROWER  IN CARE OF THE PROCESS  AGENT AT THE  PROCESS  AGENT'S
ABOVE ADDRESS,  AND THE BORROWER HEREBY  IRREVOCABLY  AUTHORIZES AND DIRECTS THE
PROCESS  AGENT TO ACCEPT SUCH SERVICE ON ITS BEHALF.  THE  BORROWER  IRREVOCABLY
CONSENTS TO THE SERVICE OF PROCESS BY REGISTERED MAIL,  POSTAGE  PREPAID,  OR BY
PERSONAL  SERVICE  WITHIN OR WITHOUT  THE STATE OF NEW YORK AT THE  ADDRESS  FOR
NOTICES SPECIFIED IN SECTION 10.2. THE BORROWER HEREBY EXPRESSLY AND IRREVOCABLY
WAIVES,  TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY HAVE
OR HEREAFTER MAY HAVE TO THE LAYING OF VENUE OF ANY SUCH  LITIGATION  BROUGHT IN
ANY SUCH COURT REFERRED TO ABOVE AND ANY CLAIM THAT ANY SUCH LITIGATION HAS BEEN
BROUGHT  IN AN  INCONVENIENT  FORUM.  TO THE  EXTENT  THAT THE  BORROWER  HAS OR
HEREAFTER  MAY ACQUIRE ANY IMMUNITY FROM  JURISDICTION  OF ANY COURT OR FROM ANY
LEGAL PROCESS (WHETHER THROUGH SERVICE OR NOTICE,  ATTACHMENT PRIOR TO JUDGMENT,
ATTACHMENT  IN AID OF  EXECUTION  OR  OTHERWISE)  WITH  RESPECT TO ITSELF OR ITS
PROPERTY, THE BORROWER HEREBY IRREVOCABLY WAIVES

                                      -95-
<PAGE>



TO THE  FULLEST  EXTENT  PERMITTED  BY  LAW  SUCH  IMMUNITY  IN  RESPECT  OF ITS
OBLIGATIONS UNDER THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS.

         SECTION 10.15.  Waiver of Jury Trial. THE  ADMINISTRATIVE  AGENT,  EACH
LENDER,  EACH  ISSUER  AND  THE  BORROWER  HEREBY  KNOWINGLY,   VOLUNTARILY  AND
INTENTIONALLY  WAIVE TO THE FULLEST EXTENT  PERMITTED BY LAW ANY RIGHTS THEY MAY
HAVE TO A TRIAL BY JURY IN RESPECT OF ANY  LITIGATION  BASED HEREON,  OR ARISING
OUT OF, UNDER, OR IN CONNECTION WITH, THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT,
OR ANY  COURSE  OF  CONDUCT,  COURSE OF  DEALING,  STATEMENTS  (WHETHER  ORAL OR
WRITTEN) OR ACTIONS OF THE ADMINISTRATIVE AGENT, SUCH LENDER, SUCH ISSUER OR THE
BORROWER IN CONNECTION  HEREWITH OR  THEREWITH.  THE BORROWER  ACKNOWLEDGES  AND
AGREES THAT IT HAS RECEIVED FULL AND SUFFICIENT CONSIDERATION FOR THIS PROVISION
(AND EACH OTHER  PROVISION  OF EACH OTHER LOAN  DOCUMENT TO WHICH IT IS A PARTY)
AND THAT THIS PROVISION IS A MATERIAL  INDUCEMENT FOR THE ADMINISTRATIVE  AGENT,
EACH LENDER AND EACH ISSUER  ENTERING  INTO THIS  AGREEMENT  AND EACH SUCH OTHER
LOAN DOCUMENT.

Without  limiting  clause (c), any Lender may assign or  otherwise  transfer (in
whole or in part) any Note or Loan held by it to any other Person or entity, and
such other Person or entity shall  thereupon  become  vested with all the rights
and benefits in respect  thereof  granted to such Lender under any Loan Document
(including  this  Pledge  Agreement)  or  otherwise,  subject,  however,  to any
contrary  provisions in such  assignment or transfer,  and to the  provisions of

transfer  or other  disposition  of  Collateral  in  accordance  with the Credit
Agreement or (ii) the occurrence of the Termination Date, the security interests
granted herein shall automatically terminate with respect to (x) such Collateral
(in the case of clause (i)) or (y) all  Collateral (in the case of clause (ii)),
and at such time the  Administrative  Agent will, at the Pledgor's sole expense,
deliver to the applicable Pledgor,  without any  representations,  warranties or
recourse of any kind whatsoever,  all  certificates  and instruments  previously
delivered to an  Administrative  Agent  representing  or evidencing  all Pledged
Interests,  together with all other Collateral held by the Administrative  Agent
hereunder,  and execute and deliver to the Pledgor such documents as the Pledgor
shall reasonably request to evidence such termination.


                                   ARTICLE III
                         REPRESENTATIONS AND WARRANTIES

3.1. SECTION Representations and Warranties, etc. In order to induce the Secured
Parties  to enter  into  the  Credit  Agreement  and to make  Credit  Extensions
thereunder,  the Pledgor  represents  and warrants to each Secured  Party as set
forth in this Article.

         SECTION 3.1.1.  Ownership,  No Liens, etc. The Pledgor is the legal and
beneficial  owner of, and has good and  marketable  title to (and has full right
and authority to pledge and assign) its Collateral, free and clear of all Liens,
options and other charges,  except any Lien granted  pursuant hereto in favor of
the Secured Parties.

         SECTION 3.1.2. Valid Security  Interest.  The execution and delivery of
this  Pledge  Agreement,  together  with (a)(i) in the case of  Collateral  that
constitutes  a  Certificated  Interest,  the delivery of such  Collateral to the
Administrative Agent together with undated stock powers executed in blank by the
Pledgor,  (ii) in the case of  Collateral  that  constitutes  an  uncertificated
security,   the   registration   with  the  Pledged   Interest  Issuer  of  such
uncertificated  security,  or (iii) in the case of Collateral  that  constitutes
Pledged Notes,  delivery of such Collateral and an allonge to such Collateral to
the  Administrative  Agent,  or (b) in  the  case  of  other  than  Certificated
Interests,  the filing of U.C.C.  financing  statements  in the  filing  offices
listed on Attachment 1 hereto, is effective to create a valid, perfected,  first
priority security interest in such Collateral and all proceeds thereof, securing
the Secured  Obligations.  Possession by the Administrative Agent of the Pledged
Interests,  if  certificated,  or  registration  by the  Pledgor of the  Pledged
Interests, if uncertificated, is the only action necessary to perfect or protect
such  security  interest  in the Pledged  Interests  and the  proceeds  thereof,
subject to Section 9-306 of the U.C.C.

         SECTION 3.1.3.  As to Pledged Interests.  In the case of

                  percentage  of the  issued and  outstanding  shares of Capital
                  Stock,   Partnership   Interests,   LLC  Interests  and  other
                  ownership  interest of each Pledged  Interest Issuer set forth
                  on Attachment I hereto; and

(ii)              the Pledgor has delivered to the Administrative Agent true and
                  complete copies of the partnership,  membership,  operating or
                  ownership agreements, as applicable, for each Pledged Interest
                  Issuer that is a LLC or a  Partnership,  which  agreements are
                  currently  in full force and effect and have not been  amended
                  or modified except as disclosed to the Administrative Agent in
                  writing;

(b)      each Pledged Note, all of such Pledged Notes have been duly authorized,
         executed,  endorsed, issued and delivered, and are the legal, valid and
         binding obligation of the issuers thereof, and are not in default.

         SECTION  3.1.4.  Location of Pledgor.  The  jurisdictions  in which the
Pledgor is located for  purposes of Sections  9-103 and 9-104 of the U.C.C.  are
set forth in Attachment 1 hereto.

         SECTION  3.1.5.  Nature  of  Pledged  Interests.  No LLC  Interests  or
Partnership Interests are represented by certificates.


                                   ARTICLE IV
                                    COVENANTS

4.1.  SECTION  Covenants.  The Pledgor  covenants  and agrees that, at all times
prior to the Termination Date, it will perform,  comply with and be bound by the
obligations set forth in this Article.

4.1.1.  SECTION  Protect  Collateral;   Further  Assurances,  etc.  The  Pledgor
covenants  and  agrees  that it will not  sell,  assign,  transfer,  pledge,  or
encumber  in  any  other  manner  the   Collateral   (except  in  favor  of  the
Administrative  Agent hereunder).  The Pledgor will warrant and defend the right
and title herein granted unto the Administrative  Agent in and to the Collateral
(and all right,  title, and interest  represented by the Collateral) against the
claims and demands of all other  Persons.  The Pledgor  agrees that from time to
time, at the expense of the Pledgor,  it will  promptly  execute and deliver all
further  instruments,  and take all further  action,  that may be  necessary  or
desirable,  or that either Administrative Agent may reasonably request, in order
to perfect and protect any security  interest granted or purported to be granted
hereby or to enable the  Administrative  Agent to  exercise  and  enforce  their
rights and remedies  hereunder with respect to any Collateral.  The Pledgor will
not, without thirty (30) days' prior written notice to the Administrative Agent,
(i) change its name or structure so as to make any financing or other  statement
filed  pursuant to this Pledge  Agreement  become  seriously  misleading or (ii)
change the  jurisdiction in which it is located to other than those specified in


         Section 3.1.4. The Pledgor will pledge hereunder,  immediately upon its
acquisition   (directly  or   indirectly)   thereof,   any  and  all  additional
Indebtedness  owed to the  Pledgor  pursuant  to any note with an  Obligor.  The
Pledgor further covenants and agrees as follows:

                  (a) If the Pledgor  shall become  entitled to receive or shall
         receive  any  stock or other  certificate  (including  any  certificate
         representing  a  Dividend  or a  Distribution  in  connection  with any
         reclassification,  increase or reduction of capital or any  certificate
         issued  in  connection  with any  reorganization),  option  or  rights,
         whether in addition to, in  substitution  of, as a conversion of, or in
         exchange  for any portion of the  Collateral  (or  otherwise in respect
         thereof),  the  Pledgor  shall  accept  the  same as the  agent  of the
         Administrative  Agent,  hold the same in trust  for the  Administrative
         Agent and deliver the same forthwith to the Administrative Agent in the
         exact form  received,  duly  endorsed  (in blank) by the Pledgor to the
         Administrative Agent, if required, together with an undated stock power
         or other  necessary  instrument of transfer  covering such  certificate
         duly executed in blank by the Pledgor, to be held by the Administrative
         Agent,  subject to the terms of this Pledge  Agreement,  as  additional
         security for the Secured Obligations.  In addition,  any sums paid upon
         or in respect of the Collateral  upon the liquidation or dissolution of
         any Pledged Interest Issuer shall be held by the  Administrative  Agent
         as  additional  security  for the Secured  Obligations.  If any sums of
         money or property so paid or  distributed  in respect of any Collateral
         shall be received by the Pledgor,  then the Pledgor  shall,  until such
         money or property is paid or  delivered  to the  Administrative  Agent,
         hold such money or property in trust for the  Administrative  Agent (on
         behalf of the  Secured  Parties),  segregated  from other  funds of the
         Pledgor, as additional collateral securing the Secured Obligations.

                  (b)  Except as  otherwise  expressly  permitted  by the Credit
         Agreement,  without  the prior  written  consent of the  Administrative
         Agent,  the Pledgor will not (i) consent to any material  modification,
         extension or alteration of the terms of any partnership,  membership or
         operating  agreement of the LLCs or the  Partnerships  or (ii) accept a
         surrender of any partnership,  membership or operating agreement of any
         of the LLCs or the Partnerships,  as applicable, or waive any breach of
         or default under any such agreement by any other party thereto.

                  (c) The Pledgor will advise the Administrative Agent promptly,
         in reasonable  detail (i) of any Lien or claim made or asserted against
         any material part of the Collateral, (ii) of any material change in the
         composition of the Collateral, and (iii) of the occurrence of any other
         event  relating  specifically  to the Pledgor or its assets which could
         reasonably  be  expected  to  have a  material  adverse  effect  on the
         aggregate value of the Collateral or on the security  interests created
         hereunder.

4.1.2.  SECTION  Registration of Pledged Interests,  etc.  Concurrently with the
execution and delivery of this Pledge  Agreement,  the Pledgor shall execute and
deliver to the applicable  Pledged  Interest  Issuer  instructions  to register,
substantially  in the form of Exhibit A hereto,  and cause each Pledged Interest
Issuer  to  execute  and  deliver  to  the  Administrative   Agent  the  Initial
Transaction Statement, substantially in the form of Exhibit B hereto, confirming
that each Pledged  Interest Issuer (in which the Pledgor owns a Pledged Interest
(other  than in the case of a  Certificated  Interest  or a Pledged  Note))  has
registered  the pledge by the Pledgor  effected by this Pledge  Agreement on its
books.  In  addition,  the  Pledgor  agrees  that it shall  cause each Issuer of
Certificated  Securities to execute and deliver to the  Administrative  Agent an
acknowledgment in a form satisfactory to the Administrative Agent.

4.1.3.  SECTION  Stock  Powers,  etc. The Pledgor  agrees that all  Certificated
Interests  constituting  Collateral  delivered  by the Pledgor  pursuant to this
Pledge  Agreement  will be  accompanied  by duly  executed  undated  blank stock
powers,  or  other  equivalent   instruments  of  transfer   acceptable  to  the
Administrative  Agent, as are necessary under all applicable laws to perfect the
Lien in favor of the Secured Parties on such Collateral.  The Pledgor will, from
time to time upon the request of the Administrative  Agent,  promptly deliver to
the Administrative Agent such stock powers, instruments,  and similar documents,
satisfactory in form and substance to the Administrative  Agent, with respect to
the Collateral as the Administrative Agent may reasonably request and will, from
time to time upon the request of the Administrative  Agent after the occurrence,
and during the  continuance,  of any Event of  Default,  promptly  transfer  any
Pledged Interests or other shares of Capital Stock or other ownership  interests
constituting  Collateral  into  the  name  of  any  nominee  designated  by  the
Administrative Agent.

4.1.4.  SECTION  Continuous Pledge. The Pledgor will, at all times, keep pledged
to the Administrative  Agent pursuant hereto all Pledged Interests and all other
shares of Capital Stock or other ownership  interests  constituting  Collateral,
all Dividends and Distributions  with respect thereto (provided that if no Event
of Default or Default  described in Section 8.1.9 of the Credit  Agreement shall
have occurred or be continuing, such Dividends and Distributions may be used for
working capital or other purposes),  all Pledged Notes, all interest,  principal
and other  proceeds  received by the  Administrative  Agent with  respect to the
Pledged  Notes,  and all other  Collateral  and other  securities,  instruments,
proceeds,  and rights  from time to time  received  by or  distributable  to the
Pledgor in respect of any  Collateral  and will not permit any Pledged  Interest
Issuer to issue any Capital Stock or other  ownership  interests which shall not
have been  immediately  duly  pledged  hereunder on a first  priority  perfected
basis.

4.1.5.            SECTION   Voting Rights; Dividends, etc.  The Pledgor agrees:

(a)      after any  Default of the nature  referred  to in Section  8.1.9 of the
         Credit  Agreement  or any Event of Default  shall have  occurred and be
         continuing,  promptly upon receipt of notice thereof by the Pledgor and
         without  any  request  therefor by either  Administrative  Agent,  such
         Pledgor  will  deliver  (properly  endorsed  where  required  hereby or
         requested by the Administrative  Agent) to the Administrative Agent all
         Dividends,  Distributions, all other cash payments, and all proceeds of
         the Collateral,  all of which shall be held by the Administrative Agent
         for the benefit of the Secured Parties as additional Collateral for use
         in accordance with Section 6.4; and

(b)      after any Event of Default shall have  occurred and be  continuing  and
         the Administrative Agent has notified the Pledgor of the Administrative
         Agent's intention to exercise its voting power under this Section.

(i)               the Administrative Agent may exercise (to the exclusion of the
                  Pledgor) the voting power and all other  incidental  rights of
                  ownership  with  respect  to any  Pledged  Interests  or other
                  shares  of  Capital   Stock  or  other   ownership   interests
                  constituting  Collateral  and the  Pledgor  hereby  grants the
                  Administrative  Agent an irrevocable proxy,  exercisable under
                  such  circumstances,  to vote the Pledged  Interests  and such
                  other Collateral; and

(ii)              promptly   to  deliver  to  the   Administrative   Agent  such
                  additional  proxies  and  other  documents  requested  by  the
                  Administrative   Agent  as  may  be  necessary  to  allow  the
                  Administrative Agent to exercise such voting power.

All Dividends,  Distributions,  cash payments and proceeds which may at any time
and from  time to time be held by the  Pledgor  but which  the  Pledgor  is then
obligated to deliver to the Administrative  Agent,  shall, until delivery to the
Administrative  Agent, be held by the Pledgor  separate and apart from its other
property in trust for the Secured Parties.  The Administrative Agent agrees that
unless  an Event of  Default  shall  have  occurred  and be  continuing  and the
Administrative  Agent shall have given the notice referred to in clause (b), the
Pledgor  shall have the  exclusive  voting  power with  respect to any shares of
Capital  Stock  or  other  ownership  interests  (including  any of the  Pledged
Interests)  constituting Collateral and the Administrative Agent shall, upon the
written  request  of the  Pledgor,  promptly  deliver  such  proxies  and  other
documents,  if any, as shall be  reasonably  requested by the Pledgor  which are
necessary to allow the Pledgor to exercise voting power with respect to any such
share of  Capital  Stock  or other  ownership  interests  (including  any of the
Pledged Interests)  constituting  Collateral;  provided,  however,  that no vote
shall be cast, or consent, waiver, or ratification given, or action taken by the
Pledgor that would impair any Collateral or be inconsistent  with or violate any
provision of the Credit Agreement or any other Loan Document.

4.1.6. SECTION Additional Undertakings.  The Pledgor will not, without the prior
written consent of the Administrative Agent, take or omit to take any action the
taking or the omission of which could result in any  impairment or alteration of
any instrument  constituting  Collateral.  In furtherance of the foregoing,  the
Pledgor  agrees  that it will not,  without  the prior  written  consent  of the
Administrative Agent which consent shall not be unreasonably withheld:

(a)      enter  into any  agreement  amending,  supplementing,  or  waiving  any
         provision  of any Pledged Note  (including  any  underlying  instrument
         pursuant  to which such  Pledged  Note is issued)  or  compromising  or
         releasing or extending  the time for payment of any  obligation  of the
         maker thereof; or

(b)      take or omit to take any  action the  taking or the  omission  of which
         would result in any  impairment or alteration of any  obligation of the
         maker of any Pledged Note or other instrument constituting Collateral.

SECTION  4.1.7.  Pledgor  Remains  Liable.   Anything  herein  to  the  contrary
notwithstanding,

                  (a) the  Pledgor  shall  remain  liable to perform  all of its
         duties and  obligations  as an owner of the Pledged  Interests,  to the
         same extent as if this Pledge Agreement had not been executed;

                  (b) the exercise by either  Administrative  Agent or any other
         Secured  Party of any of its rights  hereunder  shall not  release  the
         Pledgor from any of its duties or  obligations  as owner of the Pledged
         Interests; and

                  (c) neither  Administrative  Agent nor any other Secured Party
         shall  have any  obligation  or  liability  as an owner of any  Pledged
         Interest as applicable, by reason of this Pledge Agreement.


                                    ARTICLE V
                                    THE AGENT

5.1. SECTION Administrative Agent Appointed Attorney-in-Fact. The Pledgor hereby
irrevocably appoints the Administrative Agent as the Pledgor's attorney-in-fact,
with full authority in the place and stead of the Pledgor and in the name of the
Pledgor  or  otherwise,   from  time  to  time  in  the  Administrative  Agent's
discretion,  after the occurrence and during the continuance of a Default of the
nature  referred to in Section 8.1.9 of the Credit  Agreement or any other Event
of  Default,  to take any  action  and to  execute  any  instrument  which  such
Administrative  Agent may deem necessary or advisable to accomplish the purposes
of this Pledge Agreement:

(a)      to ask, demand, collect, sue for, recover, compromise, receive and give
         acquittance  and  receipts for moneys due and to become due under or in
         respect of any of the Collateral;

(b)      to  receive,  endorse,  and  collect  any drafts or other  instruments,
         documents and chattel paper, in connection with clause (a); and

(c)      to file any  claims or take any  action or  institute  any  proceedings
         which such Administrative Agent may deem necessary or desirable for the
         collection of any of the  Collateral or otherwise to enforce the rights
         of such Administrative Agent with respect to any of the Collateral.

The Pledgor hereby acknowledges,  consents and agrees that the power of attorney
granted pursuant to this Section is irrevocable and coupled with an interest.

5.2. SECTION  Administrative  Agent May Perform. If the Pledgor fails to perform
any agreement  contained herein, the Administrative  Agent may perform, or cause
performance   of,  such   agreement,   and  the   reasonable   expenses  of  the
Administrative  Agent  incurred  in  connection  therewith  shall be jointly and
severally payable by the Pledgor pursuant to Section 6.4.

5.3.  SECTION  Administrative  Agent Have No Duty.  The powers  conferred on the
Administrative Agent hereunder are solely to protect its interests (on behalf of
the Secured  Parties) in the  Collateral  and shall not impose any duty on it to
exercise any such powers.  Except for  reasonable  care of any Collateral in its
possession and the accounting for moneys actually received by it hereunder,  the
Administrative  Agent shall have no duty as to any Collateral or  responsibility
for

(a)      ascertaining  or taking  action  with  respect  to calls,  conversions,
         exchanges, maturities, tenders or other matters relative to any Pledged
         Property,  whether or not the Administrative  Agent has or is deemed to
         have knowledge of such matters, or

(b)      taking any necessary  steps to preserve rights against prior parties or
         any other rights pertaining to any Collateral.

5.4. SECTION Reasonable Care. The  Administrative  Agent is required to exercise
reasonable care in the custody and  preservation of any of the Collateral in its
possession;  provided, however, the Administrative Agent shall be deemed to have
exercised  reasonable  care  in  the  custody  and  preservation  of  any of the
Collateral  if it takes such action for that  purpose as the Pledgor  reasonably
requests  in writing  at times  other  than upon the  occurrence  and during the
continuance of any Event of Default.  The failure of the Administrative Agent to
comply with any such request at any time shall not in itself be deemed a failure
to exercise reasonable care.


                                   ARTICLE VI
                                    REMEDIES

6.1. SECTION Certain  Remedies.  If any Event of Default shall have occurred and
be continuing:

(a)       The Administrative Agent may exercise in respect of the Collateral, in
          addition to other rights and remedies provided for herein or otherwise
          available  to it, all the rights and  remedies  of a secured  party on
          default  under the U.C.C.  (whether  or not the U.C.C.  applies to the
          affected  Collateral) and also may, without notice except as specified
          below,  sell the Collateral or any part thereof in one or more parcels
          at public or private sale, at any of the Administrative Agent' offices
          or  elsewhere,  for cash, on credit or for future  delivery,  and upon
          such other  terms as the  Administrative  Agent may deem  commercially
          reasonable.  The Pledgor  agrees  that,  to the extent  notice of sale
          shall be  required  by law,  at least  ten days'  prior  notice to the
          Pledgor  of the time and place of any  public  sale or the time  after
          which  any  private  sale is to be made  shall  constitute  reasonable
          notification.  The Administrative Agent shall not be obligated to make
          any sale of Collateral regardless of notice of sale having been given.
          The  Administrative  Agent may adjourn any public or private sale from
          time to time by announcement at the time and place fixed therefor, and
          such sale may,  without further notice,  be made at the time and place
          to which it was so adjourned.

(b)       The Administrative Agent may

(i)               transfer  all or any part of the  Collateral  into the name of
                  the  Administrative  Agent  or its  nominee,  with or  without
                  disclosing  that  such  Collateral  is  subject  to  the  Lien
                  hereunder,

(ii)              notify the parties  obligated on any of the Collateral to make
                  payment  to the  Administrative  Agent of any amount due or to
                  become due thereunder,

(iii)             enforce  collection  of any  of  the  Collateral  by  suit  or
                  otherwise, and surrender,  release or exchange all or any part
                  thereof,  or  compromise  or extend  or renew  for any  period
                  (whether  or  not  longer  than  the   original   period)  any
                  obligations of any nature of any party with respect thereto,

(iv)              endorse any checks, drafts, or other writings in the Pledgor's
                  name to allow collection of the Collateral,

(v)               take control of any proceeds of the Collateral, and

(vi)              execute  (in  the  name,  place  and  stead  of  the  Pledgor)
                  endorsements,  assignments, stock powers and other instruments
                  of  conveyance  or transfer  with respect to all or any of the
                  Collateral.

6.2. [SECTION  Securities Laws. If the  Administrative  Agent shall determine to
exercise  their right to sell all or any of the  Collateral  pursuant to Section
6.1, the Pledgor  agrees that,  upon request of the  Administrative  Agent,  the
Pledgor will, at the Pledgor's own expense:

(a)       execute  and  deliver,   and  cause  each  issuer  of  the  Collateral
          contemplated  to be sold and the  directors  and  officers  thereof to
          execute and deliver,  all such  instruments  and documents,  and do or
          cause to be done all such other acts and things,  as may be  necessary
          or, in the opinion of the Administrative Agent,  advisable to register
          such Collateral under the provisions of the Securities Act of 1933, as
          from  time to time  amended  (the  "Securities  Act")  and  comparable
          legislation  in other  jurisdictions,  and to cause  the  registration
          statement relating thereto to become effective and to remain effective
          for such period as  prospectuses  are required by law to be furnished,
          and to make all amendments and supplements  thereto and to the related
          prospectus  which,  in the opinion of the  Administrative  Agent,  are
          necessary or advisable, all in conformity with the requirements of the
          Securities  Act and the rules and  regulations  of the  Securities and
          Exchange  Commission  applicable  thereto and comparable  legislation,
          rules and regulations in other jurisdictions;

(b)      use its  best  efforts  to  qualify  the  Collateral  under  the  state
         securities or "Blue Sky" laws and to obtain all necessary  governmental
         approvals  for  the  sale  of  the  Collateral,  as  requested  by  the
         Administrative Agent;

(c)      cause  each  such  Pledged  Interest  Issuer to make  available  to its
         security holders,  as soon as practicable,  an earnings  statement that
         will satisfy the  provisions of Section 11(a) of the Securities Act and
         comparable legislation in other jurisdictions; and

(d)      do or  cause  to be done  all such  other  acts  and  things  as may be
         necessary to make such sale of the Collateral or any part thereof valid
         and binding and in compliance with applicable law.

The Pledgor further acknowledges the impossibility of ascertaining the amount of
damages  that would be  suffered  by the  Administrative  Agent and the  Secured
Parties by reason of the failure by the Pledgor to perform any of the  covenants
contained in this Section and,  consequently,  agrees that, if the Pledgor shall
fail to perform  any of such  covenants,  the Pledgor  shall pay, as  liquidated
damages and not as a penalty, an amount equal to the value (as determined by the
Administrative  Agent) of the  Collateral on the date the  Administrative  Agent
shall demand compliance with this Section.]

6.3. SECTION Compliance with  Restrictions.  The Pledgor agrees that in any sale
of any of the Collateral whenever an Event of Default shall have occurred and be
continuing,  the  Administrative  Agent is hereby  authorized to comply with any
limitation or restriction in connection with such sale as they may be advised by
counsel  is  necessary  in  order to  avoid  any  violation  of  applicable  law
(including  compliance  with  such  procedures  as may  restrict  the  number of
prospective  bidders and purchasers,  require that such prospective  bidders and
purchasers have certain  qualifications,  and restrict such prospective  bidders
and  purchasers to persons who will represent and agree that they are purchasing
for their own account for investment and not with a view to the  distribution or
resale of such  Collateral),  or in order to obtain any required approval of the
sale or of the purchaser by any governmental  regulatory  authority or official,
and the Pledgor  further  agrees that such  compliance  shall not result in such
sale  being  considered  or  deemed  not to have  been  made  in a  commercially
reasonable manner, nor shall the Administrative Agent or any other Secured Party
be liable nor accountable to the Pledgor for any discount  allowed by the reason
of the fact that such  Collateral is sold in compliance with any such limitation
or restriction.

6.4.  SECTION  Application  of  Proceeds.  All  cash  proceeds  received  by the
Administrative  Agent  in  respect  of any sale of,  collection  from,  or other
realization  upon, all or any part of the  Collateral  may, in the discretion of
the  Administrative  Agent,  be held by the  Administrative  Agent as additional
collateral  security for, or then or at any time  thereafter  be applied  (after
payment of any amounts payable to the  Administrative  Agent pursuant to Section
10.3  of the  Credit  Agreement  and  Section  6.5) in  whole  or in part by the
Administrative Agent against, all or any part of the Secured Obligations in such
order as the Administrative Agent shall elect.

         Any surplus of such cash or cash  proceeds  held by the  Administrative
Agent and remaining after the occurrence of the  Termination  Date shall be paid
over to the Pledgor or to  whomsoever  may be lawfully  entitled to receive such

(b)        be binding  upon the  Grantor  and its  successors,  transferees  and
           assigns; and

(c)        inure,  together  with the rights and remedies of the  Administrative
           Agent hereunder,  to the benefit of the Administrative Agent and each
           other Secured Party.

Without  limiting the  generality  of the  foregoing  clause (c), any Lender may
assign or otherwise  transfer (in whole or in part) any Note or Credit Extension
held by it to any other Person or entity,  and such other Person or entity shall
thereupon  become  vested with all the rights and  benefits  in respect  thereof
granted  to such  Lender  under  any  Loan  Document  (including  this  Security
Agreement) or otherwise,  subject,  however,  to any contrary provisions in such
assignment or transfer, and to the provisions of Section 10.11 and Article IX of
the  Credit  Agreement.  Upon (i) the sale,  transfer  or other  disposition  of
Collateral in accordance with the Credit Agreement or (ii) the occurrence of the
Termination  Date, the security  interests  granted  herein shall  automatically
terminate with respect to (x) such Collateral (in the case of clause (i)) or (y)
all Collateral (in the case of clause (ii)), and at such time the Administrative
Agent will,  at the Grantor's  sole expense,  execute and deliver to the Grantor
(without  any  representations,  warranties  or recourse  to the  Administrative
Agent),  such documents as the Grantor shall reasonably request to evidence such
termination.

SECTION  2.4  Grantor   Remains   Liable.   Anything   herein  to  the  contrary
notwithstanding

(a)      the Grantor  shall remain  liable under the  contracts  and  agreements
         included in the Collateral to the extent set forth  therein,  and shall
         perform  all of its duties and  obligations  under such  contracts  and
         agreements  to the same extent as if this  Security  Agreement  had not
         been executed;

(b)      the exercise by the Administrative Agent of any of its rights hereunder
         shall not  release the  Grantor  from any of its duties or  obligations
         under any such contracts or agreements included in the Collateral; and

(c)      neither the Administrative Agent nor any other Secured Party shall have
         any  obligation  or liability  under any such  contracts or  agreements
         included in the  Collateral by reason of this Security  Agreement,  nor
         shall the Administrative  Agent or any other Secured Party be obligated
         to perform any of the  obligations or duties of the Grantor  thereunder
         or to take any  action to  collect  or  enforce  any claim for  payment
         assigned hereunder.

         Locations");  provided,  however,  that the  Grantor  may  move  and/or
         maintain  certain  items  of  Equipment  at  locations  other  than  at
         Specified  Locations so long as the value of Collateral of this type of
         the  Grantor  and  similar  Collateral  (as  defined in the  Subsidiary
         Security  Agreement) of the Restricted  Subsidiaries,  shall not exceed
         $2,000,000 at any time;

(b)      cause  the  Equipment  to be  maintained  and  preserved  in  the  same

         improvements  in connection  therewith which are necessary or desirable
         to  such  end;  and  promptly  furnish  to the  Administrative  Agent a

         Default shall have occurred or be  continuing)  and make abstracts from
         such records and chattel paper. In addition, the Grantor shall give the
         Administrative  Agent a supplement  to Schedule I hereto  ---------- on

         any   changes  to  the   information   set  forth  in  Section   3.1.1.


(b)      Upon written notice by the Administrative Agent to the Grantor pursuant
         to this  clause,  all  proceeds of  Collateral  received by the Grantor
         shall be delivered in kind to the Administrative Agent for deposit to a
         deposit account (the  "Collateral  Account") of the Grantor  maintained
         with the Administrative  Agent, and the Grantor shall not commingle any
         such  proceeds,  and  shall  hold  separate  and  apart  from all other
         property,  all such  proceeds  in express  trust for the benefit of the
         Administrative   Agent   until   delivery   thereof   is  made  to  the
         Administrative Agent. The Administrative Agent will not give the notice
         referred to in the preceding  sentence unless there shall have occurred
         and be continuing a Default of the nature set forth in Section 8.1.9 of
         the Credit Agreement or an Event of Default.

(c)      The  Administrative  Agent  shall have the right to apply any amount in
         the Collateral Account to the payment of any Secured  Obligations which
         are due and payable or payable  upon  demand,  or to the payment of any
         Secured Obligations at any time that an Event of Default shall exist.

(d)      The  Grantor  shall not cause the  aggregate  value of  Receivables  or
         Related  Contracts  or  rights  thereunder  and the  value  of  similar
         Receivables  and  Related  Contracts  (as  defined  in  the  Subsidiary
         Security  Agreement) as to which a Lien in favor of the  Administrative
         Agent  cannot be granted  hereunder  pursuant  to clause (c) of Section
         2.1,  or  pursuant  to the  Subsidiary  Security  Agreement,  to exceed
         $2,000,000 at any time.

4.1.3. SECTION As to Collateral.

(a)      Until the  occurrence  and  continuance  of a Default of the nature set
         forth in Section 8.1.9 of the Credit  Agreement or an Event of Default,
         and such time as the  Administrative  Agent shall notify the Grantor of
         the  revocation  of such power and  authority  the  Grantor  may in the
         ordinary  course of its business  (except as otherwise  permitted under
         the Credit Agreement), at its own expense, sell, lease or furnish under
         the  contracts  of service any of the  Inventory  normally  held by the
         Grantor for such purpose,  and use and consume,  in the ordinary course
         of its  business  (except  as  otherwise  permitted  under  the  Credit
         Agreement),  any raw materials,  work in process or materials  normally
         held by the  Grantor  for  such  purpose,  will,  at its  own  expense,
         endeavor to collect,  as and when due,  all amounts due with respect to
         any of the Collateral, including the taking of such action with respect
         to such collection as the  Administrative  Agent may reasonably request
         following  the  occurrence  of a  Default  of the  nature  set forth in
         Section 8.1.9 of the Credit Agreement or an Event of Default or, in the
         absence of such  request,  as the Grantor may deem  advisable,  and may
         grant,  in  the  ordinary  course  of  business  (except  as  otherwise
         permitted under the Credit Agreement), to any party obligated on any of
         the Collateral, any rebate, refund or allowance to which such party may
         be lawfully  entitled,  and may accept,  in connection  therewith,  the
         return of goods,  the sale or lease of which  shall  have given rise to
         such Collateral.  The Administrative  Agent,  however, may, at any time
         following  a Default of the  nature  set forth in Section  8.1.9 of the
         Credit  Agreement or an Event of Default,  whether  before or after any
         revocation  of such power and  authority  or the maturity of any of the
         Secured  Obligations,  notify  any  parties  obligated  on  any  of the
         Collateral to make payment to the  Administrative  Agent of any amounts
         due or to become due  thereunder  and enforce  collection of any of the
         Collateral by suit or otherwise and surrender, release, or exchange all
         or any part  thereof,  or  compromise or extend or renew for any period
         (whether  or not longer  than the  original  period)  any  indebtedness
         thereunder  or evidenced  thereby.  Upon request of the  Administrative
         Agent  following a Default of the nature set forth in Section  8.1.9 of
         the Credit  Agreement or an Event of Default,  the Grantor will, at its
         own expense,  notify any parties  obligated on any of the Collateral to
         make  payment  to the  Administrative  Agent of any  amounts  due or to
         become due thereunder.

(b)      The Administrative  Agent is authorized to endorse,  in the name of the
         Grantor,  any item,  howsoever  received by the  Administrative  Agent,
         representing any payment on or other proceeds of any of the Collateral.

4.1.4. SECTION As to Intellectual Property Collateral. The Grantor covenants and
agrees to comply with the following  provisions as such provisions relate to any
Intellectual Property Collateral of the Grantor that:

(a)      The Grantor shall not,  unless the Grantor shall either (i)  reasonably
         and in good faith  determine  (and notice of such  determination  shall
         have been delivered to the Administrative Agent) that any of the Patent
         Collateral is of negligible economic value to the Grantor, or (ii) have
         a valid business purpose to do otherwise, do any act, or omit to do any
         act, whereby any of the Patent Collateral may lapse or become abandoned
         or dedicated to the public or unenforceable.

(b)      The  Grantor  shall not,  and the  Grantor  shall not permit any of its
         licensees  to, unless the Grantor  shall either (i)  reasonably  and in
         good faith determine (and notice of such determination  shall have been
         delivered  to the  Administrative  Agent)  that  any  of the  Trademark
         Collateral is of negligible economic value to the Grantor, or (ii) have
         a valid business purpose to do otherwise,

(i)               fail to continue  to use any of the  Trademark  Collateral  in
                  order to  maintain  all of the  Trademark  Collateral  in full
                  force free from any claim of abandonment for non-use,

(ii)              fail to maintain  as in the past the  quality of products  and
                  services offered under all of the Trademark Collateral,

                  notice of such registration,

(iv)              adopt or use any other Trademark which is confusingly  similar
                  or a colorable imitation of any of the Trademark Collateral,

(v)               use  any of  the  Trademark  Collateral  registered  with  any
                  Federal or state or foreign  authority except for the uses for
                  which  registration or application for  registration of all of
                  the Trademark Collateral has been made, and

(vi)              do or permit any act or  knowingly  omit to do any act whereby
                  any of the Trademark Collateral may lapse or become invalid or
                  unenforceable.

(c)       The Grantor shall not, unless the Grantor shall either

(i)               reasonably  and in good faith  determine  (and  notice of such
                  determination  shall have been delivered to the Administrative
                  Agent)  that  any of the  Copyright  Collateral  or any of the
                  Trade Secrets  Collateral is of negligible  economic  value to
                  the Grantor, or

(ii)              have a valid  business  purpose to do otherwise,  do or permit
                  any act or  knowingly  omit to do any act  whereby  any of the
                  Copyright  Collateral or any of the Trade  Secrets  Collateral
                  may lapse or become invalid or  unenforceable or placed in the
                  public  domain  except  upon  expiration  of  the  end  of  an
                  unrenewable term of a registration thereof.

(d)      The Grantor shall notify the  Administrative  Agent  immediately  if it
         knows,  or has reason to know,  that any  application  or  registration
         relating to any material item of the Intellectual  Property  Collateral
         may become abandoned or dedicated to the public or placed in the public
         domain or invalid or unenforceable,  or of any adverse determination or
         development (including the institution of, or any such determination or
         development  in,  any  proceeding  in  the  United  States  Patent  and
         Trademark  Office,  the United States  Copyright  Office or any foreign
         counterpart  thereof or any court) regarding the Grantor's ownership of
         any of the Intellectual Property Collateral,  its right to register the
         same or to keep and maintain and enforce the same.

(e)      In no  event  shall  the  Grantor  or  any of  its  agents,  employees,
         designees or licensees file an application for the  registration of any
         Intellectual  Property  Collateral  with the United  States  Patent and
         Trademark  Office,  the United States  Copyright  Office or any similar
         office  or agency in any other  country  or any  political  subdivision
         thereof, unless it promptly upon such filing informs the Administrative
         Agent,  and upon  request of the  Administrative  Agent,  executes  and
         delivers any and all agreements,  instruments,  documents and papers as
         the  Administrative  Agent  may  reasonably  request  to  evidence  the
         Administrative  Agent's security interest in such Intellectual Property
         Collateral  and the  goodwill  and general  intangibles  of the Grantor
         relating thereto or represented thereby.

(f)      The Grantor shall take all necessary steps, including in any proceeding
         before the United States Patent and Trademark Office, the United States
         Copyright  Office or any similar  office or agency in any other country
         or any  political  subdivision  thereof,  to  maintain  and  pursue any
         application  (and to  obtain  the  relevant  registration)  filed  with
         respect  to, and to  maintain  any  registration  of, the  Intellectual
         Property Collateral,  including the filing of applications for renewal,
         affidavits  of use,  affidavits  of  incontestability  and  opposition,
         interference and  cancellation  proceedings and the payment of fees and

         required to  acknowledge  or  register  or perfect  the  Administrative
         Agent's interest in any part of the Intellectual Property Collateral.

4.1.5.  SECTION  Insurance.  The Grantor will maintain or cause to be maintained
with responsible  insurance companies insurance with respect to its business and
properties  (including the Equipment and Inventory)  against such casualties and
contingencies  and of such types and in such amounts as is required  pursuant to
the Credit  Agreement and will,  upon the request of the  Administrative  Agent,
furnish a certificate of a reputable  insurance  broker setting forth the nature
and extent of all insurance  maintained  by the Grantor in accordance  with this
Section. Without limiting the foregoing, the Grantor further agrees as follows:

(a)      Each policy for property insurance shall show the Administrative  Agent
         as loss payee.

(b)      Each policy for liability insurance shall show the Administrative Agent
         as an additional insured.

(c)      Each  insurance  policy  shall  provide  that at least  30 days'  prior
         written  notice  of  cancellation  or of  lapse  shall  be given to the
         Administrative Agent by the insured (or at least 10 days' prior written
         notice of  cancellation  shall be given with  respect to failure to pay
         the premium).

(d)      The Grantor shall, if so requested by the Administrative Agent, deliver
         to the Administrative Agent a copy of each insurance policy.

4.1.6. SECTION Transfers and Other Liens. The Grantor shall not:

(a)      sell, assign (by operation of law or otherwise) or otherwise dispose of
         any of the Collateral, except as permitted by the Credit Agreement; or

(b)      create or suffer to exist any Lien or other charge or encumbrance  upon
         or with respect to any of the Collateral to secure  Indebtedness of any
         Person or entity,  except  for the  security  interest  created by this
         Security Agreement and except as permitted by the Credit Agreement.

4.1.7.  SECTION Further  Assurances,  etc. The Grantor agrees that, from time to
time at its own  expense,  it will  promptly  execute  and  deliver  all further
instruments and documents, and take all further action, that may be necessary or
desirable (provided that it is reasonable), or that the Administrative Agent may
reasonably  request,  in order to perfect,  preserve  and  protect any  security
interest   granted  or  purported  to  be  granted   hereby  or  to  enable  the
Administrative  Agent to exercise and enforce its rights and remedies  hereunder
with  respect  to  any  Collateral.  Without  limiting  the  generality  of  the
foregoing, the Grantor will

(a)      mark  conspicuously  each document  (evidencing  title) included in the
         Inventory,  each chattel  paper  included in the  Receivables  and each
         Related Contract and, at the request of the Administrative  Agent, upon
         the occurrence  and during the  continuance of an Event of Default each
         of its records  pertaining to the Collateral with a legend, in form and
         substance  satisfactory to the  Administrative  Agent,  indicating that
         such document, chattel paper, Related Contract or Collateral is subject
         to the security interest granted hereby;

(b)      if any  Receivable  shall be evidenced  by a  promissory  note or other
         instrument, negotiable document or chattel paper, deliver and pledge to
         the  Administrative  Agent hereunder such promissory note,  instrument,
         negotiable  document or chattel paper duly endorsed and  accompanied by
         duly executed  instruments of transfer or  assignment,  all in form and
         substance satisfactory to the Administrative Agent;

(c)      execute  and  file  such  financing  or  continuation  statements,   or
         amendments  thereto,  and such other instruments or notices [(including
         any  assignment  of  claim  form  under  or  pursuant  to  the  federal
         assignment  of claims  statute,  31 U.S.C.  ss. 3726,  any successor or
         amended version thereof or any regulation promulgated under or pursuant
         to any version  thereof)],  as may be necessary or desirable  (provided
         that it is reasonable),  or as the Administrative  Agent may reasonably
         request,  in order to perfect and preserve the security  interests  and
         other rights  granted or purported to be granted to the  Administrative
         Agent hereby; and

(d)      furnish  to  the  Administrative  Agent,  from  time  to  time  at  the
         Administrative  Agent's  request,   statements  and  schedules  further
         identifying  and  describing  the  Collateral and such other reports in
         connection  with  the  Collateral  as  the  Administrative   Agent  may
         reasonably request, all in reasonable detail.

With respect to the foregoing and the grant of the security interest  hereunder,
the  Grantor  hereby  authorizes  the  Administrative  Agent to file one or more
financing or continuation statements, and amendments thereto, relative to all or
any part of the Collateral  without the signature of the Grantor where permitted
by law. A carbon,  photographic or other reproduction of this Security Agreement
or any financing  statement covering the Collateral or any part thereof shall be
sufficient as a financing statement where permitted by law.


                                    ARTICLE V

                            THE ADMINISTRATIVE AGENT

5.1. SECTION Administrative Agent Appointed Attorney-in-Fact. The Grantor hereby
irrevocably  appoints the Administrative  Agent the Grantor's  attorney-in-fact,
with full authority in the place and stead of the Grantor and in the name of the
Grantor  or  otherwise,   from  time  to  time  in  the  Administrative  Agent's
discretion, following the occurrence and continuation of a Default of the nature
set forth in Section  8.1.9 of the Credit  Agreement or an Event of Default,  to
take any action and to execute any instrument which the Administrative Agent may
deem  necessary  or  advisable  to  accomplish  the  purposes  of this  Security
Agreement, including:

(a)      to ask, demand, collect, sue for, recover, compromise, receive and give
         acquittance  and  receipts for moneys due and to become due under or in
         respect of any of the Collateral;

(b)      to  receive,  endorse,  and  collect  any drafts or other  instruments,
         documents and chattel paper, in connection with clause (a) above;

(c)      to file any  claims or take any  action or  institute  any  proceedings
         which the Administrative  Agent may deem necessary or desirable for the
         collection of any of the  Collateral or otherwise to enforce the rights
         of the Administrative Agent with respect to any of the Collateral; and

(d)      to  perform  the  affirmative  obligations  of  the  Grantor  hereunder
         (including all obligations of the Grantor pursuant to Section 4.1.7).

The Grantor hereby acknowledges,  consents and agrees that the power of attorney
granted pursuant to this Section is irrevocable and coupled with an interest.

5.2. SECTION  Administrative  Agent May Perform. If any Grantor fails to perform
any agreement contained herein, the Administrative  Agent may itself perform, or
cause  performance  of, such agreement,  and the expenses of the  Administrative
Agent incurred in connection  therewith shall be payable by the Grantor pursuant
to Section 6.2.

5.3.  SECTION  Administrative  Agent Has No Duty.  In  addition  to,  and not in
limitation of,  Section 2.4, the powers  conferred on the  Administrative  Agent
hereunder are solely to protect its interest (on behalf of the Secured  Parties)
in the  Collateral  and shall not  impose  any duty on it to  exercise  any such
powers.  Except for reasonable  care of any Collateral in its possession and the
accounting  for moneys  actually  received by it hereunder,  the  Administrative
Agent  shall  have no  duty  as to any  Collateral  or as to the  taking  of any
necessary  steps to preserve  rights  against  prior parties or any other rights
pertaining to any Collateral.

         SECTION 5.4.  Reasonable Care. The Administrative  Agent is required to
exercise  reasonable  care  in  the  custody  and  preservation  of  any  of the
Collateral in its possession;  provided, however, the Administrative Agent shall
be deemed to have exercised  reasonable care in the custody and  preservation of
any of the  Collateral,  if it takes such action for that purpose as any Grantor
reasonably  requests  in writing at times  other  than upon the  occurrence  and
during  the   continuance   of  any  Event  of  Default,   but  failure  of  the
Administrative  Agent to comply  with any such  request at any time shall not in
itself be deemed a failure to exercise reasonable care.

                                   ARTICLE VI

                                    REMEDIES

6.1. SECTION Certain  Remedies.  If any Event of Default shall have occurred and
be continuing:

(a)      The Administrative Agent may exercise in respect of the Collateral,  in
         addition to other rights and remedies  provided for herein or otherwise
         available  to it,  all the rights and  remedies  of a secured  party on
         default  under the U.C.C.  (whether  or not the  U.C.C.  applies to the
         affected Collateral) and also may

(i)               require the Grantor to, and the Grantor  hereby agrees that it
                  will,  at its expense and upon  request of the  Administrative
                  Agent  forthwith,  assemble all or part of the  Collateral  as
                  directed by the Administrative  Agent and make it available to
                  the  Administrative  Agent at a place to be  designated by the
                  Administrative  Agent which is  reasonably  convenient to both
                  parties, and

(ii)              without notice except as specified below,  sell the Collateral
                  or any  part  thereof  in one or more  parcels  at  public  or
                  private sale, at any of the Administrative  Agent's offices or
                  elsewhere,  for cash,  on credit or for future  delivery,  and
                  upon such  other  terms as the  Administrative  Agent may deem
                  commercially  reasonable.  The  Grantor  agrees  that,  to the
                  extent  notice of sale shall be  required by law, at least ten
                  days' prior notice to the Grantor of the time and place of any
                  public sale or the time after which any private  sale is to be
                  made   shall   constitute   reasonable    notification.    The
                  Administrative  Agent shall not be  obligated to make any sale
                  of Collateral  regardless of notice of sale having been given.
                  The  Administrative  Agent may  adjourn  any public or private
                  sale from time to time by  announcement  at the time and place
                  fixed therefor,  and such sale may, without further notice, be
                  made at the time and place to which it was so adjourned.

(iii)             All cash  proceeds  received  by the  Administrative  Agent in
                  respect of any sale of,  collection from, or other realization
                  upon all or any part of the Collateral  may, in the discretion
                  of the  Administrative  Agent,  be held by the  Administrative
                  Agent as collateral for, and/or then or at any time thereafter
                  applied  (after   payment  of  any  amounts   payable  to  the
                  Administrative  Agent  pursuant to Section 6.2) in whole or in
                  part by the  Administrative  Agent for the ratable  benefit of
                  the Secured  Parties  against,  all or any part of the Secured
                  Obligations  in such order as the  Administrative  Agent shall
                  elect.  Any surplus of such cash or cash  proceeds held by the
                  Administrative  Agent and  remaining  after payment in full in
                  cash of all the Secured  Obligations shall be paid over to the
                  applicable  Grantor or to whomsoever may be lawfully  entitled
                  to receive such surplus. 6.2. SECTION Indemnity and Expenses.

(a)      The  Grantor  agrees to  indemnify  the  Administrative  Agent from and
         against any and all claims,  losses and  liabilities  arising out of or
         resulting from this Security Agreement  (including  enforcement of this
         Security  Agreement),  except claims,  losses or liabilities  resulting
         from the Administrative Agent's gross negligence or wilful misconduct.

(b)      The Grantor will upon demand pay to the Administrative Agent the amount
         of any and all reasonable  expenses,  including the reasonable fees and
         disbursements  of its counsel and of any experts and agents,  which the
         Administrative Agent may incur in connection with

(i)               the administration of this Security Agreement,

(ii)              the custody,  preservation,  use or operation  of, or the sale
                  of,  collection  from, or other  realization  upon, any of the
                  Collateral, and

(iii)             the  exercise  or  enforcement  of any of  the  rights  of the
                  Administrative Agent or the Secured Parties hereunder, or (iv)
                  the  failure by any  Grantor to perform or observe  any of the
                  provisions hereof.


                                   ARTICLE VII

The Bank of Nova Scotia, as Administrative Agent
600 Peachtree Street, N.E., Suite 2700

Re:  The Titan Corporation

Ladies and Gentlemen:

listed in Exhibit "A" attached hereto; and

     o. copies of the good  standing/status  certificates  listed in Exhibit "B"
attached hereto.

For purposes of this opinion, the agreements,  documents,  notes and instruments
referred  to in  clauses  (a)  through  (l) above are  hereinafter  collectively
referred to as the "Transaction Documents". The Persons described on Exhibit "C"
are sometimes  collectively  referred to herein as the "New  Subsidiaries."  The
Persons described on Exhibit "D" are sometimes  collectively  referred to herein
as the "Existing Subsidiaries".

Based  upon  the  foregoing,  and  subject  to  the  limitations,   assumptions,
exceptions  and  qualifications  set forth below, I am of the opinion that as of
the date hereof:

     1.       The Borrower is (i) a corporation  duly  incorporated and existing
              and in good  standing  under  the laws of  Delaware  and (ii) duly
              qualified to do business in each jurisdiction  where the nature of
              its business requires such qualification  except where the failure
              to so qualify would not constitute a Material Adverse Effect.  The
              Borrower  has full power and  authority,  and holds all  requisite
              governmental licenses,  permits and other approvals, to enter into
              and perform its  Obligations  under each  Transaction  Document to
              which it is a party and to conduct its business  substantially  as
              currently conducted by it.

     2.       Each New  Subsidiary is (i) a corporation  duly  incorporated  and
              existing and in good  standing  under the laws of the state of its
              incorporation  and (ii)  duly  qualified  to do  business  in each
              jurisdiction  where  the  nature  of its  business  requires  such
              qualification  except  where the  failure to so qualify  would not
              constitute a Material Adverse Effect. Each New Subsidiary has full
              power  and  authority,   and  holds  all  requisite   governmental
              licenses,  permits and other approvals,  to enter into and perform
              its Obligations  under each Transaction  Document to which it is a
              party and to  conduct  its  business  substantially  as  currently
              conducted  by it such  that the  failure  to hold  such  licenses,
              permits,  and other  approvals  would not  constitute  a  Material
              Adverse Effect.

     3.       The Borrower has duly authorized by all necessary corporate action
              the  execution,  delivery  and  performance  of  each  Transaction
              Document to which it is a party,  and the execution,  delivery and
              performance thereof do not

              (a)     contravene the Organic Documents of the Borrower;

              (b)     contravene any law or  governmental  regulation or, to the
                      best of my knowledge, any contractual  restriction,  court
                      decree or order binding on or affecting the Borrower,  the
                      contravention  of  which  constitute  a  Material  Adverse
                      Effect; or

              (c)     result in, or require the creation or  imposition  of, any
                      Lien under any agreement or  instrument on any  properties
                      of  the  Borrower,  other  than  a Lien  in  favor  of the
                      Administrative   Agent   pursuant   to  the   terms  of  a
                      Transaction Document.

<PAGE>

     4.       Each  New  Subsidiary  and  each  Existing   Subsidiary  has  duly
              authorized  by  all  necessary  corporate  action  the  execution,
              delivery and performance of each Transaction  Document to which it
              is a party, and the execution, delivery and performance thereof do
              not

              (a)     contravene the Organic Documents of such New Subsidiary or
                      Existing Subsidiary, as the case may be;

              (b)     contravene any law or  governmental  regulation or, to the
                      best of my knowledge, any contractual  restriction,  court
                      decree  or  order   binding  on  or  affecting   such  New
                      Subsidiary or Existing Subsidiary, as the case may be, the
                      contravention  of  which  constitute  a  Material  Adverse
                      Effect; or

              (c)     result in, or require the creation or  imposition  of, any
                      Lien under any agreement or  instrument on any  properties
                      of such New Subsidiary or Existing Subsidiary, as the case
                      may be,  other than a Lien in favor of the  Administrative
                      Agent pursuant to the terms of a Transaction Document.

     5.       No  authorization or approval or other action by, and no notice to
              or filing with, any  governmental  authority or regulatory body is
              required for the due  execution,  delivery or  performance  by the
              Borrower or any New  Subsidiary  or Existing  Subsidiary of any of
              the  Transaction  Documents to which it is a party and which would
              contribute a Material Adverse Effect.

     6.       There is no pending,  nor, to the best of my  knowledge  after due
              inquiry, threatened litigation, action, proceeding,  investigation
              or  labor  controversy  affecting  the  Borrower  or  any  of  its
              properties,  business,  assets  or  revenues  which  may  cause  a
              Material  Adverse Effect or which purports to affect the legality,
              validity or enforceability of any of the Transaction Documents.

     7.       There is no pending,  nor, to the best of my  knowledge  after due
              inquiry, threatened litigation, action, proceeding,  investigation
              or labor controversy affecting each New Subsidiary,  each Existing
              Subsidiary or any of its properties,  business, assets or revenues
              which may cause a Material  Adverse  Effect or which  purports  to
              affect the  legality,  validity  or  enforceability  of any of the
              Transaction Documents.

     8.       The  Pledged   Interests  (as  defined  in  the  Borrower   Pledge
              Agreement),  other than Pledged  Notes (as defined in the Borrower
              Pledge  Agreement),  issued  by the  New  Subsidiaries  listed  in
              Attachment  I to the  Borrower  Pledge  Supplement  have been duly
              authorized and validly issued,  are fully paid and  non_assessable
              and constitute all of the issued and  outstanding  shares of stock
              of such New Subsidiaries.

<PAGE>

     9        The  Pledged  Interests  (as  defined  in  the  Subsidiary  Pledge
              Agreement), other than Pledged Notes (as defined in the Subsidiary
              Pledge  Agreement),  issued  by the  New  Subsidiaries  listed  in
              Attachment I to the Subsidiary  Pledge  Supplement  have been duly
              authorized and validly issued,  are fully paid and  non_assessable
              and constitute all of the issued and  outstanding  shares of stock
              of such New Subsidiaries.

I assume for purposes of this opinion that each individual, corporation, limited
liability  company,  partnership,   association,   joint_stock  company,  trust,
unincorporated organization, joint venture or Governmental Authority (foreign or
domestic) (each, a "Person") who is a party to any of the Transaction  Documents
(other than the Borrower, the New Subsidiaries and the Existing Subsidiaries) is
duly  organized,  validly  existing and in good  standing  under the laws of its
jurisdiction of organization;  that each of such Transaction  Documents has been
duly  authorized by each Person who is a party thereto (other than the Borrower,
the  New  Subsidiaries  and  the  Existing  Subsidiaries);   that  each  of  the
Transaction Documents has been duly executed and delivered by each Person who is
a party thereto (other than the Borrower,  the New Subsidiaries and the Existing
Subsidiaries)  and constitutes or will  constitute the legal,  valid and binding
obligation of each Person (other than the Borrower, the New Subsidiaries and the
Existing Subsidiaries),  enforceable in accordance with its terms; and that each
Person  (other  than  the  Borrower,  the  New  Subsidiaries  and  the  Existing
Subsidiaries)  that is a party to any  Transaction  Document  has the  requisite
corporate or other organizational power and authority to perform its obligations
under such  Transaction  Document.  I am not  expressing  any  opinion as to the
effect of any compliance or non_compliance  by any agent,  bank, or other lender
with any state or federal laws or  regulations  applicable  to the  transactions
contemplated by the Transaction Documents because of the nature of such Person's
business.

For  purposes of my opinions in  paragraphs  1 and 2 above with  respect to good
standing, I have relied upon the certificates  described in Exhibit "B" attached
hereto.

Whenever a statement  herein is qualified by "knowledge" or any similar  phrase,
it is intended  to  indicate  that,  during the course of my  representation  of
Borrower,  the New  Subsidiaries and the Existing  Subsidiaries,  no information
that would give me current actual  knowledge of the inaccuracy of such statement
has come to my attention.

The opinions expressed above are limited to the laws of the State of California,
the general corporate laws of the State of Delaware, and the Federal laws of the
United States, and do not express any opinion herein concerning any other law.

I express no opinion  regarding any laws, rules or regulations that relate to or
limit the effect of the Transaction Documents with respect to contracts with any
governmental  agency involving  matters of national  security or other sensitive
military or governmental activities.

As to  certain  factual  matters,  we  have,  with  your  consent,  relied  upon
certificates or opinions of officers,  counsel or other  representatives  of the
Borrower and the  Subsidiaries  and the  representations  and  warranties of the
Borrower and the  Subsidiaries  in the Loan Documents,  all without  independent
verification  by us.  In  addition,  we  have  obtained  and  relied  upon  such
certificates and assurances from public officials as we have deemed necessary.

We have  investigated  such  questions of law for the purpose of rendering  this
opinion as we have deemed  necessary.  Members of our firm who are involved with
this matter are admitted to the bars in the States of  California  and New York.
For the purposes of our opinion, we have assumed,  with your consent and without
independent  investigation,  the correctness and accuracy of the opinion,  dated
June 9, 1999,  of Ira Frazer,  Esq.,  general  counsel to the  Borrower.  We are
opining  herein only as to the effect on the subject  transaction of the present
internal laws of the States of New York and  California and Federal law (without
regard  to  conflicts  of laws or  principles),  excluding  municipal  and local
ordinances  and  regulations.   We  express  no  opinion  with  respect  to  the
applicability  to or the effect on the  subject  transaction  of the laws of any
other  jurisdiction.  We  expressly  disclaim  any  responsibility  to revise or
supplement  this opinion should any such laws be changed by, or  compilations of
any such laws be updated to reflect,  legislative or regulatory action, judicial
decision  or  otherwise  after the date  hereof.  Nor do we opine upon any laws,
rules or  regulations  that relate to or limit the effect of the Loan  Documents
with respect to contracts  with any  governmental  agency  involving  matters of
national security or other sensitive military or governmental activities.

                       GENERAL ASSUMPTIONS AND LIMITATIONS

Our  opinions  expressed  below are  subject to the  following  assumptions  and
limitations:

         (1) We have assumed the  genuineness of all signatures on the documents
reviewed  by us,  the  authenticity  of all such  documents  submitted  to us as
originals,  and the conformity to the originals of all such documents  submitted
to us as photocopies or conformed  copies and the  authenticity of the originals
of such latter documents.

         (2) We have assumed that: (i) the Administrative  Agent and the Lenders
have not waived,  subordinated or agreed to any  modification of the attachment,
perfection or priority of the security  interests  created by the Loan Documents
or acted in any way inconsistent with the maintenance,  perfection,  or priority
of such security interests; (ii) the tangible personal property constituting the
Collateral located in California and described on the Financing Statements filed
in the appropriate California  governmental office will at all relevant times be

<PAGE>

located in the State of  California;  (iii) at all relevant  times,  each of the
parties to the Loan  Documents  (a) is validly  existing and in good standing in
the respective jurisdiction of its organization and has satisfied all applicable
governmental  requirements and other laws and requirements,  in each case to the
extent  necessary  to its  execution,  delivery  and  performance  of  the  Loan
Documents to which it is a party,  (b) has the  requisite  power and  authority,
respectively, to act with respect to the authorization,  execution, delivery and
performance of such documents and agreements to which it is a party, and (c) has
duly and validly  authorized,  executed and delivered each of such documents and
agreements to which it is a party; (iv) the execution,  delivery and performance
of the Loan Documents by each party do not conflict with,  result in a breach or
violation of, or  constitute a default  under,  any of the terms,  conditions or
provisions of the articles or  certificate of  incorporation  or by_laws of each
such party;  and (v) the Loan  Documents  are  enforceable  against  each of the
parties  (other  than  the  Borrower,  the New  Subsidiaries  and  the  Existing
Subsidiaries) in accordance with their terms.

         (3) We have assumed that: (i) other than the Loan Documents,  there are
no agreements or understandings among the parties, written or oral, and no usage
of trade or course of prior  dealing  among the parties  which would,  in either
case, define, modify, limit,  supplement or qualify the terms of any of the Loan
Documents,  and (ii) each of the Borrower, the New Subsidiaries and the Existing
Subsidiaries has rights in the Collateral owned by it such that each item of the
Collateral  constitutes  property  in which a security  interest  can be granted
under  the UCC,  and that each of the  Borrower,  the New  Subsidiaries  and the
Existing Subsidiaries has received value under the Transaction Documents, all as
required  by  Section  9_203 of the UCC for a  security  interest  to  attach to
collateral and be enforceable.

         (4) We have  assumed  that  all  applicable  California  taxes  due and
payable by the Administrative Agent and the Lenders have been paid.

                                    OPINIONS

Based  upon the  foregoing,  and  subject  to the  limitations,  qualifications,
assumptions and exceptions set forth below, we are of the opinion that:

2.  Each  of  the  Transaction  Documents  to  which  the  Borrower  is a  party
constitutes the legal, valid and binding obligation of the Borrower  enforceable
against the Borrower in accordance with its terms.

3. Each of the  Transaction  Documents to which each New  Subsidiary  is a party
constitutes  the legal,  valid and  binding  obligation  of such New  Subsidiary
enforceable against such New Subsidiary in accordance with its terms.

4.  The  Subsidiary  Guaranty,   as  supplemented  by  the  Subsidiary  Guaranty
Supplement, and as reaffirmed by the Obligor Affirmation, constitutes the legal,
valid and binding  obligation  of each  Subsidiary  party  thereto,  enforceable
against such Subsidiary in accordance with its terms.

5. The Borrower Pledge Agreement, as amended by the Obligor Affirmation, creates
a valid security interest in favor of the Administrative Agent in the Collateral
(as  defined  in the  Borrower  Pledge  Agreement,  as  amended  by the  Obligor
Affirmation),  as security for the Secured  Obligations,  and the Administrative
Agent having and maintaining  possession of the  certificates  representing  the
Pledged  Interests  (as defined in the Borrower  Pledge  Agreement),  other than
Pledged Notes (as defined in the Borrower Pledge Agreement), together with stock
powers duly  executed in blank by the Borrower  delivered to the  Administrative
Agent today results in the perfection of such security  interest,  and, further,
the Administrative Agent is a "protected purchaser" of such Pledged Interests.

6. The Subsidiary  Pledge  Agreement,  as supplemented by the Subsidiary  Pledge
Supplement,  creates a valid  security  interest in favor of the  Administrative
Agent in the  Collateral  (as defined in the  Subsidiary  Pledge  Agreement,  as
supplemented by the Subsidiary Pledge  Supplement),  as security for the Secured
Obligations,  and the Administrative Agent having and maintaining  possession of
the  certificates   representing  the  Pledged  Interests  (as  defined  in  the
Subsidiary  Pledge  Agreement),  other  than  Pledged  Notes (as  defined in the
Subsidiary Pledge Agreement),  together with stock powers duly executed in blank
by the relevant Subsidiary  delivered to the Administrative  Agent today results
in the perfection of such security  interest,  and, further,  the Administrative
Agent is a "protected purchaser" of such Pledged Interests.

7. The  provisions of the Borrower  Security  Agreement are effective  under the
laws of the State of New York to create in favor of the  Administrative  Agent a
legal and valid  security  interest  in all  right,  title and  interest  of the
Borrower in and to all Borrower Collateral,  in which a security interest can be
created  under  the UCC (the  "Borrower  UCC  Collateral"),  including,  without
limitation (a) all "equipment" and "inventory" (each as defined in the UCC), now
or  hereafter  owned  by the  Borrower,  and  located  in  California,  (b)  all
"accounts"  and  "general  intangibles"  (each  as  defined  in the  UCC) now or
hereafter owned by the Borrower, to the extent that the Borrower is deemed to be
located in  California  within the meaning of Section  9_103 of the UCC, and (c)
all  "proceeds"  (as  defined  in the  UCC)  of such  "equipment",  "inventory",
"accounts" and "general  intangibles" (located in California or, with respect to
intangible  collateral,  to the extent the  Borrower  continues to be located in
California within the meaning of Section 9_103 of the UCC).

8. The provisions of the Subsidiary Security  Agreement,  as supplemented by the
Subsidiary Security Supplement, are effective under the laws of the State of New
York to create in favor of the  Administrative  Agent a legal and valid security
interest  in all right,  title and  interest  of each  Subsidiary  in and to all
Subsidiary Collateral, in which a security interest can be created under the UCC
(the  "Subsidiary  UCC  Collateral"),  including,  without  limitation  (a)  all
"equipment" and "inventory" (each as defined in the UCC), now or hereafter owned
by each Subsidiary,  and located in California,  (b) all "accounts" and "general
intangibles"  (each  as  defined  in the  UCC)  now or  hereafter  owned by each
Subsidiary,  to the  extent  that each  Subsidiary  is deemed to be  located  in
California  within  the  meaning  of  Section  9_103  of the  UCC,  and  (c) all
"proceeds" (as defined in the UCC) of such "equipment",  "inventory", "accounts"
and "general  intangibles" (located in California or, with respect to intangible
collateral,  to the  extent  each such  Subsidiary  continues  to be  located in
California within the meaning of Section 9_103 of the UCC).

9. The Financing  Statements that are to be filed in California (the "California
Financing  Statements")  are in appropriate form for filing under the California
UCC and,  upon the  filing of such  Financing  Statements  in the  office of the
California Secretary of State (the "Filing Office") and the payment of customary
fees and  charges  which are  required  in  connection  with such  filings,  the
Administrative Agent's security interest in all right, title and interest of the
Borrower  and  the  Subsidiaries  in and  to the  Borrower  UCC  Collateral  and
Subsidiary UCC Collateral, respectively, shall be fully perfected, to the extent
that a security  interest in such  collateral  can be perfected by the filing of
such financing statements in such office.

10. Except for the filing of the  Financing  Statements in the Filing Office and
the payment of the fees and charges  described  in  paragraph 8 above,  no other
recordation or filing need be made, and no other action need be taken,  in order
to perfect or maintain the  perfection of the  Administrative  Agent's  security
interest in the Borrower UCC Collateral and the Subsidiary UCC Collateral to the
extent such  security  interest may be perfected  under the laws of  California,
other than the filings and actions described above (regarding Pledged Interests)
or below.

11. No consent,  approval,  authorization or order of, or filing or registration
with, any Federal or New York State  governmental  agency or body is required to
be made in  connection  with the  execution,  delivery  and  performance  by the
Borrower of the Transaction Documents to which it is a party.

12. The  Copyright  Security  Agreements  create in favor of the  Administrative
Agent a valid security  interest in each of the copyrights  listed in Schedule A
thereto  which is duly and validly  registered  in the United  States  Copyright

<PAGE>

Office (each a "Copyright" and collectively the  "Copyrights").  Upon the proper
filing of the  California  Financing  Statements in the office of the California
Secretary of State and the recordation of the Copyright  Security  Agreements in
the  United  States  Copyright  Office,  the  Administrative  Agent  will have a
perfected  security  interest in each Copyright to the extent the holder of each
Copyright is located in  California  within the meaning of Section  9-103 of the
UCC.

13. The Patent Security Agreements create in favor of the Administrative Agent a
valid  security  interest  in each of the  patents  listed in Schedule A thereto
which is duly and  validly  issued by the United  States  Patent  and  Trademark
Office (each a "Patent" and collectively the "Patents").  Upon the proper filing
of the California Financing Statements in the office of the California Secretary
of State and the  recordation  of the Patent  Security  Agreements in the United
States  Patent  and  Trademark  Office,  the  Administrative  Agent  will have a
perfected  security  interest  in each  Patent to the  extent the holder of each
Patent is located in California within the meaning of Section 9-103 of the UCC.

14. The  Trademark  Security  Agreements  create in favor of the  Administrative
Agent a valid security  interest in each of the trademarks  listed in Schedule A
thereto  which is duly and validly  registered  in the United  States Patent and
Trademark Office (each a "Trademark" and collectively  the  "Trademarks").  Upon
the proper filing of the  California  Financing  Statements in the office of the
California  Secretary of State and the  recordation  of the  Trademark  Security
Agreements in the United States Patent and Trademark Office,  the Administrative
Agent will have a perfected  security  interest in each  Trademark to the extent
the holder of each  Trademark  is located in  California  within the  meaning of
Section 9-103 of the UCC.

15.  Each of the  Existing  Documents  remain in full  force and  effect and the
security  interests (and the perfection of such security interests to the extent
such security  interests are  perfected  immediately  prior to the execution and
delivery of the  Transaction  Documents)  created by the  Existing  Documents in
favor of the  Administrative  Agent will not become unperfected by reason of the
execution and delivery of the Credit Agreement.


                     ADDITIONAL ASSUMPTIONS, QUALIFICATIONS,
                           LIMITATIONS AND EXCEPTIONS

Our  opinions   expressed   above  are  subject  to  the  following   additional
qualifications, assumptions, limitations and exceptions:

<PAGE>

         (i) Our opinion is based upon our review only of those laws,  statutes,
rules and  regulations  which,  in our  experience,  are normally  applicable to
transactions  which are  similar to the  transactions  contemplated  by the Loan
Documents,  and we are not expressing any opinion as to the effect of compliance
by any party to the Loan Documents with any laws, statutes, rules or regulations
applicable to the transactions  because of the nature of such party's  business,
and we have assumed that the  Borrower,  the Existing  Subsidiaries  and the New
Subsidiaries are not subject to any licensing or other  regulatory  requirements
or  provisions  under New York,  California  or  Federal  law,  other than those
generally affecting persons conducting  business for profit,  which would affect
the ability of the Borrower,  the Existing  Subsidiaries or the New Subsidiaries
to perform their respective  obligations under the Loan Documents.  However,  to
our  best  knowledge,  the  Borrower,  the  Existing  Subsidiaries  and  the New
Subsidiaries are not subject to any licensing or other  regulatory  requirements
or provisions under New York, California or Federal law (other than (a) security
clearance  required for government  contracts and (b) regulations  that apply to
Persons doing business with the United State government).

         (ii) Whenever a statement herein is qualified by "known to us", "to our
best knowledge" or similar phrase,  it is intended to indicate that,  during the
course of our representation of the Borrower,  the Existing Subsidiaries and the
New Subsidiaries,  no information that would give us current actual knowledge of
the inaccuracy of such statement has come to the attention of those attorneys in
this firm who have rendered legal services in connection with the representation
described in the  introductory  paragraph of this opinion  letter.  We have not,
however,  undertaken  any further  independent  investigation  to determine  the
accuracy of any such statement,  and any limited inquiry undertaken by us during
the  preparation  of this  opinion  letter  should  not be  regarded  as such an
investigation or imply that we have any duty to make such an  investigation;  no
inference as to our knowledge of any matters bearing on the accuracy of any such
statement should be drawn from the fact of our  representation  of the Borrower,
the Existing  Subsidiaries  and the New  Subsidiaries  in  connection  with this
transaction.

         (iii) For purposes of our  opinions 4 and 5 above,  (i) we have assumed
that the  Administrative  Agent and the other  Lenders do not have notice of any
adverse  claim to the  Pledged  Interests,  (ii) the  Collateral  defined in the
Borrower Pledge  Agreement (as amended) and the Subsidiary  Pledge Agreement (as
amended by the  Subsidiary  Pledge  Supplement)  is and will  remain  physically
within the State of New York, (iii) "protected purchaser" shall have the meaning
set  forth in UCC  Section  8303,  and (iv)  such  opinions  do not apply to any



<PAGE>

proceeds  or other  distributions  received  in  connection  therewith.  For the
purposes of opinions 11 through 13 above we have  assumed that the holder of the
Copyrights, Patents and Trademarks at the time of filing and recordation of each
of the Copyright  Security  Agreements,  the Patent Security  Agreements and the
Trademark Security  Agreements,  respectively,  is as indicated on the Schedules
attached thereto.

         (iv) Our  opinions  set  forth in  paragraphs  1, 2, 3 and 14 above are
limited by the following:

                  a)   applicable    bankruptcy,    receivership,    insolvency,
reorganization,  moratorium or other similar laws  affecting the  enforcement of
the rights and remedies of creditors,  secured  parties and parties to executory
contracts  generally;  and such duties and standards as are or may be imposed on
creditors,    including,    without   limitation,   good   faith,   materiality,
reasonableness,  and fair dealing under the UCC or any other  applicable  law or
judicial decision; and

                  b) general  principles of equity  (regardless  of whether such
enforceability  is  considered  in a  proceeding  in  equity  or at law) and the
exercise  of  equitable  powers  by a court of  competent  jurisdiction  (and no
opinion is given herein as to any specific or equitable relief of any kind or as
to the availability of equitable remedies);

         (v) Our opinions are limited by the following:

                  a)  applicable  laws relating to  fraudulent  conveyances  and
preferential transfers, as to which we express no opinion; and

                  b) law and public  policy  governing  provisions of any of the
Loan  Documents   providing   contribution   to  a  party  or   indemnifying  or
prospectively releasing a party with respect to a liability.

         (vi) Our opinions are subject to the  constitutionality  and  continued
validity of all statutes and laws  reviewed and relied upon by us in  connection
with rendering the opinions set forth herein.

         (vii) We  advise  you that  courts  may not  strictly  enforce  certain
covenants  contained in the Loan Documents or allow acceleration of the maturity
of the debt  evidenced  by  thereby if it  concludes  that such  enforcement  or
acceleration would be unreasonable under the then existing circumstances.

         (viii) We  express no opinion  as to the  validity,  enforceability  or
perfection  of any security  interest in (a) any property  with respect to which
any federal filing, registration or consent is necessary to assign or perfect an
interest therein (except as expressly stated in paragraphs 11, 12 and 13 above),



<PAGE>

(b) any  equipment,  rail cars or vehicles as to which  perfection of a security
interest is dependent  upon a notation  being made on a certificate  of title or
the like,  (c) any  property  the  creation  of a security  interest in which is
excluded from the California UCC or the UCC (e.g.,  claims for wages, loans made
by an insurance company,  rights of setoff, tort claims, etc.), (d) any consumer
goods,  equipment used in farming  operations,  farm products,  crops, timber or
minerals and the like  (including  oil and gas) or accounts  resulting  from the
sale  thereof,  any  beneficial  interest in a trust or a  decedent's  estate or
letters  of  credit  (all as  defined  in the  California  UCC or the  UCC),  or
accounts,  chattel paper, documents,  instruments or general intangibles (all as
defined in the UCC) which are or will be due from the United  States,  any state
of the United States,  county,  municipality or other  governmental  body or any
agency, department or instrumentality thereof, unless the same has been assigned
to the Lenders pursuant to the Assignment of Claims Act of 1940, as amended,  or
any similar law or regulation  relating to the assignment or pledge thereof;  in
that connection,  however, the creation and perfection of a security interest in
such  collateral  is  accomplished  under the Loan  Documents  together with the
filing  of the  Borrower  Financing  Statements  and  the  Subsidiary  Financing
Statements  and the  Administrative  Agent's  taking  possession  of the Pledged
Interests as noted above, (e) balances,  credits,  deposits,  accounts,  deposit
accounts or monies  maintained  at an office or branch of the Lenders other than
an office or branch located within the State of California,  (f) goods which are
moveable  in  nature,  (g) any  interest  in or claim in or under any  policy of
insurance,  except a claim to proceeds payable by reason of loss or damage under
insurance policies maintained with respect to inventory or equipment as required
by and in compliance with the Loan  Documents,  (h) goods as against a consignor
which has  delivered or may hereafter  deliver such goods to the  Borrower,  the
Existing  Subsidiaries  or the New  Subsidiaries  under a true  consignment  (as
distinguished  from a  consignment  intended as  security),  (i) goods which are
installed  in or affixed  to, or become a part of a product or mass with,  goods
which are not items of Collateral,  (j) inventory in the event of any failure by
the Borrower, the Existing Subsidiaries or the New Subsidiaries to have compiled
or to comply  fully  with the Fair  Labor  Standards  Act of 1932,  as  amended,
including Sections 206 and 207 thereof, or (k) fixtures. Furthermore, we express
no opinion (a) regarding  whether any particular item of Collateral is or is not
a  "fixture",  or (b) with  respect  to the  priority  of any  lien or  security
interest  under the Loan  Documents  (other than the specific  opinion  rendered
above in paragraphs 4 and 5 regarding "protected purchasers").  We bring to your
attention the fact that security  interests in deposit  accounts  subject to the
California UCC are perfected by notice to the depositary institution, and not by
filing of a financing statement.

         (ix)  Certain  rights,  remedies,  and  waivers  contained  in the Loan
Documents may be limited or rendered  ineffective by applicable laws or judicial
decisions governing such provisions or are otherwise limited by the restrictions
of public policy.

<PAGE>

         (x) We call to your attention the fact that under the  California  UCC,
the  effectiveness of financing  statements will lapse five years after the date
of filing  thereof,  and your  security  interests  perfected  pursuant  to such
financing statements will become unperfected, unless continuation statements are
filed within six months prior to the end of such five_year  period. We also call
to your attention to the fact that security  interests  under the California UCC
perfected pursuant to such financing statements in any of the Collateral will be
terminated (a) as to any  Collateral  acquired by a debtor more than four months
after such party  changes its name,  identity or corporate  structure to such an
extent as to make its financing  statements seriously  misleading,  unless a new
appropriate   financing   statement   indicating  the  new  name,   identity  or
organizational  structure of such party is properly  filed before the expiration
of four months  after such  change and (b) as to any  collateral  consisting  of
accounts,  general  intangibles  or mobile  goods,  four  months  after a debtor
changes its chief executive  office (or, if earlier,  when perfection  under the
laws of the applicable  state would have lapsed under the first sentence of this
paragraph),   unless  such   security   interests  are  perfected  in  such  new
jurisdiction before that termination. We further call your attention to the fact
that, with respect to any collateral consisting of goods which are (a) relocated
to another  jurisdiction,  refiling  in such  jurisdiction  may be  required  to
continue perfection under the laws of such jurisdiction,  and (b) relocated from
another jurisdiction to California, refiling in California within four months is
required  to  continue  any  perfection  obtained  under  the law of such  other
jurisdiction;  provided,  however,  goods relocated from another jurisdiction to
California  complying  with the  description  of the collateral in the financing
statements (described above) will not require any such refiling.

         (xi) We bring to your  attention  the fact that (a) security  interests
granted with respect to after_acquired property are not enforceable or perfected
until the party  granting  the security  interest  has  acquired  rights in such
properties,  (b) that  certain  rights of debtors and duties of secured  parties
described  in Sections  1102(3) and 9501(3) of the  California  UCC and Sections
1_102(3) and 9_501(3) of the UCC may not be waived,  released or  disclaimed  by
agreement  prior  to  a  default,   (c)  security  interests  in  favor  of  the
Administrative  Agent  and  the  Lenders  may  be  affected  in  the  future  by
circumstances  covered by  Section  9301(4) of the  California  UCC and  Section
9_301(4) of the UCC, and (d) our opinions are further subject to the limitations
with  respect to buyers in the  ordinary  course of business  imposed by Section
9307 and 9308 of the  California UCC and Sections 9_307 and 9_308 of the UCC and
the limitations with respect to documents, instruments and securities imposed by
Section 9309 of the California UCC and Section 9_309 of the UCC.

         (xii) This  opinion  insofar as it opines on the creation of a security
interest is limited to the creation of security  interests under the laws of the
States of New York and California.

<PAGE>

         (xiii) We express  no opinion  with  respect to the  validity,  binding
effect or  enforceability  of any provision of the Loan Documents which purports
to authorize the  Administrative  Agent or the Lenders to sign or file financing
statements  without the signature of the applicable debtor (except to the extent
a secured  party may be  permitted  to  execute  and file  financing  statements
without the signature of the debtor under Section  9402(2) of the California UCC
and Section 9_402(2) of the UCC).

         (xiv) The creation or  enforceability  of any security interest granted
in accounts  receivable  is subject  (except as provided in Section  9318 of the
California  UCC and Section  9_318 of the UCC, as  applicable)  to the rights of
account debtors,  and the terms of any contracts  between the respective  debtor
and such account  debtors,  and any claims or defenses of such  account  debtors
against the respective debtor arising under or outside such contracts.

         (xv)  We  call  your   attention  to  the  fact  that,   under  certain
circumstances  described in Section 9306 of the California UCC and Section 9_306
of the UCC, the right of a secured  party to enforce a security  interest in the
proceeds  of  collateral  may be limited  (unless  the  proceeds  consist of the
collateral  described  in the  financing  statements  (described  above) and the
security interest in such proceeds can be perfected by the proper filing of such
financing statements).

         (xvi) We  advise  you that  guarantors  of  personal  property  secured
obligations  may be treated as "debtors"  under the  California UCC and the UCC,
thereby  accorded  rights and remedies of debtors  established by the California
UCC and the UCC.

         (xvii) We express no opinion as to (a) the title to or the descriptions
of, any  security  interest in any property  described in the Loan  Documents in
which a security  interest has been granted pursuant to the Loan Documents;  (b)
the existence or effect of liens, security interests,  charges,  encumbrances or
claims of right or  ownership  with  respect  thereto  (other than the  security
interests  granted  in favor of the  Administrative  Agent);  (c)  whether  such
property is the  property  intended to secure the  obligations  of the  Borrower
under the Loan Documents;  and (d) any matter affecting or in any way related to
title.  We draw your  attention to the fact that  certain  third party liens may
impact the  priority  of the  Administrative  Agent's  security  interest in the
Collateral.

         (xviii)  We  express  no  opinion  with  respect  to  the  validity  or
enforceability of any provision of the Loan Documents that:

<PAGE>

                  a) In effect, liquidates damages for the breach of a contract;

                  b) Imposes what a court may deem to be  penalties  (prepayment
penalties or otherwise),  forfeitures, late payment charges or an increased rate
of interest,  upon  delinquency  or default in the payment of sums due under the
Loan Documents or any other defaults;

                  c) Seeks to define what constitutes good faith or commercially
reasonable  behavior.  We note that a court might not permit the exercise of any
right or remedy provided in the Loan Documents if, under the circumstances  then
existing,  such exercise is deemed to be inconsistent  with the covenant of good
faith and fair dealing  implied under  applicable law to exist in all agreements
or if the party  seeking  to  exercise  such  right or remedy  fails to act in a
commercially  reasonable  manner or fails to  fulfill  other  duties  imposed by
statute or judicial  decisions.  We do  believe,  however,  that  subject to the
limitations  expressed  elsewhere in this  opinion,  enforcement  and/or (to the
extent permitted under the Loan Documents) acceleration would be available if an
event of default occurs as a result of a material breach of a material  covenant
contained in the Loan Documents;

                  d) To the extent public  policy limits  provisions of the Loan
Documents,  purports to indemnify or otherwise  exonerate  any party to the Loan
Documents  from the  consequences  of its  inadvertent  failure to take  actions
required  to be  taken by it  thereunder,  it being  acknowledged  that  certain
defenses, such as waiver, estoppel and laches, may not be waivable in any event;

                  e)  Purports  to grant  to the  Administrative  Agent  and the
Lenders any "self help" or summary remedies;

                  f) Purports to waive the right of the  Borrower,  the Existing
Subsidiaries or the New Subsidiaries to object to subject matter jurisdiction or
venue, or to assert any defense based on lack of subject matter  jurisdiction or
venue;

                  g)   Purports   to  waive   the   Borrower's,   the   Existing
Subsidiaries' or the New Subsidiaries' right to a jury trial; and/or

<PAGE>

                  h) Purports to  exculpate  or release any party  thereto  from
liability for the acts or omissions of such party proximately causing damages or
injuries as the result of such party's  ordinary or gross  negligence or willful
or intentional misconduct,  or which purports to impose a duty upon the Borrower
or any other  person,  firm or entity,  to  indemnify  any other  party when any
claimed  damages  result  from the  ordinary or gross  negligence  or willful or
intentional  misconduct of the party  seeking such  indemnity to the extent such
provisions violate public policy.

         (xix) We bring your attention to the fact that requirements in the Loan
Documents  specifying that provisions  thereof may only be waived in writing may
not be valid,  binding or enforceable to the extent that an oral agreement or an
implied  agreement  by trade  practice  or course of  conduct  has been  created
modifying any provisions of such documents.

         (xx) We express  no  opinion,  as to the  legality,  validity,  binding
nature,  enforceability  or otherwise with respect to (a) broadly stated waivers
of suretyship defenses,  presentment,  protest,  demand,  notice,  appraisement,
valuation,  stay, extension,  moratorium,  redemption or other rights granted by
law to the  extent  such  waivers  are  held  to be  against  public  policy  or
prohibited  by law, (b) any provision of any Loan Document that may be deemed to
provide for the application of monies  deposited in any account  maintained with
the  Administrative  Agent or the Lender or  collected  by any of the  foregoing
notwithstanding  that no event of default shall have occurred and be continuing,
(c) any provisions which purport to create a power of attorney,  proxy or agency
relationship,  (d) any provision in the Loan Documents that provides for a power
of  attorney  or for the  appointment  of a receiver  as a matter of right,  (e)
except as expressly  addressed by the opinions set forth above,  any schedule or
exhibit to any of the Loan Documents, (f) the enforceability of any indemnity or
reimbursement  obligation by the Borrower,  the Existing Subsidiaries or the New
Subsidiaries  concerning  environmental  remediation  or the costs of compliance
with any  environmental  protection law to the extent public policy restricts or
objects  such  provisions,  or (g) any  provision  of the  Loan  Documents  that
purports to allow a set off by the  Administrative  Agent or the Lenders against
funds held by the Borrower, the Existing Subsidiaries or the New Subsidiaries in
trust, special accounts or other segregated accounts.

         (xxi) We advise you that certain  actions may have to be  undertaken by
the  Administrative  Agent  and/or the Lenders if  revisions to Article 9 of the
Uniform  Commercial  Code  proposed by the American Law Institute are adopted by
any relevant jurisdiction.

(collectively,  the "Reliance Parties"),  or by any Reliance Party for any other

summarized or referred to in any  publication or document,  in whole or in part,
for any  purposes  whatsoever,  or furnished to any Person other than a Reliance
Party (or a Person  considering  whether to become a Reliance Party),  except as

agencies to which a Reliance Party is subject.

Very truly yours,

                                                                       EXHIBIT J



                               SUBSIDIARY GUARANTY

         This  SUBSIDIARY  GUARANTY  (as  amended,  supplemented,   amended  and
restated or otherwise  modified from time to time, the "Guaranty"),  dated as of
July 29, 1998, is made by each  Subsidiary  (such  capitalized  term,  and other
terms used in this Guaranty, to have the meanings set forth in Article I) of THE
TITAN  CORPORATION,  a Delaware  corporation (the "Borrower"),  now or after the
date  hereof  (including  pursuant  to  Section  5.5) a party  to this  Guaranty
(individually  referred to as a "Guarantor" and collectively  referred to as the

         WHEREAS, pursuant to a Credit Agreement,  dated as of July 29, 1998 (as
amended,  supplemented,  amended and restated or otherwise modified from time to
time,  the  "Credit  Agreement"),  among the  Borrower,  the  various  financial
institutions  as  are,  or  may  from  time  to  time  become,  parties  thereto
(collectively  referred to as the  "Lenders"),  the  Administrative  Agent,  and
Imperial Bank, as Documentation Agent, the Lenders and the Issuers have extended
Commitments to make Credit Extensions to the Borrower;

         WHEREAS,  as  a  condition  precedent  to  the  making  of  the  Credit
Extensions  (including the initial Credit Extension) under the Credit Agreement,
each Guarantor is required to execute and deliver this Guaranty;

         WHEREAS, each Guarantor has duly authorized the execution, delivery and
         performance of this Guaranty; and

         WHEREAS,  it is in the best interests of each Guarantor to execute this
Guaranty inasmuch as such Guarantor will derive  substantial direct and indirect
benefits  from the Credit  Extensions  made from time to time to the Borrower by
the Lenders and the Issuers pursuant to the Credit Agreement;

         NOW THEREFORE, for good and valuable consideration the receipt of which
is hereby  acknowledged,  and in order to induce the  Lenders and the Issuers to
make Credit Extensions (including the initial Credit Extension) to the Borrower,
each  Guarantor  jointly and severally  agrees,  for the benefit of each Secured
Party, as follows:

preamble and recitals, have the meanings provided in the Credit Agreement.


                                   ARTICLE II
                               GUARANTY PROVISIONS

2.1. SECTION Guaranty.  Each Guarantor hereby jointly and severally  absolutely,
unconditionally and irrevocably

(a)      guarantees  the full and punctual  payment when due,  whether at stated
         maturity, by required prepayment, declaration,  acceleration, demand or
         otherwise,  of all  Obligations  of the Borrower and each other Obligor
         now or hereafter existing,  whether for principal,  interest (including
         interest  accruing at the then  applicable  rate provided in the Credit
         Agreement  after the  occurrence  of any  Default  set forth in Section
         8.1.9 of the Credit  Agreement,  whether or not a claim for post-filing
         or post-petition interest is allowed under applicable law following the
         institution  of a proceeding  under  bankruptcy,  insolvency or similar
         laws),   fees,   Reimbursement   Obligations,   expenses  or  otherwise
         (including  all  such  amounts  which  would  become  due  but  for the
         operation  of the  automatic  stay under  Section  362(a) of the United
         States  Bankruptcy  Code,  11  U.S.C.ss.362(a),  and the  operation  of
         Sections  502(b) and 506(b) of the United  States  Bankruptcy  Code, 11
         U.S.C.ss.502(b) andss.506(b)); and


(b)      indemnifies and holds harmless each Secured Party for any and all costs
         and  expenses  (including  reasonable  attorneys'  fees  and  expenses)
         incurred  by such  Secured  Party in  enforcing  any rights  under this
         Guaranty;

provided,  however, that each Guarantor shall only be liable under this Guaranty
for the maximum  amount of such liability  that can be hereby  incurred  without
rendering  this  Guaranty,  as it  relates  to such  Guarantor,  voidable  under
applicable law relating to fraudulent conveyance or fraudulent transfer, and not
for any greater amount. This Guaranty constitutes a guaranty of payment when due
and not of collection,  and each Guarantor specifically agrees that it shall not
be necessary or required that any Secured Party  exercise any right,  assert any
claim or demand or enforce any remedy whatsoever against the Borrower, any other
Obligor or any other Person before or as a condition to the  obligations of such
Guarantor hereunder.

2.2.  SECTION  Reinstatement,  etc. Each Guarantor  hereby jointly and severally
agrees that this Guaranty shall  continue to be effective or be  reinstated,  as
the case may be, if at any time any  payment (in whole or in part) of any of the
Obligations  is  invalidated,  declared to be  fraudulent or  preferential,  set
aside,  rescinded or must otherwise be restored by any Secured  Party,  upon the
insolvency,  bankruptcy,  reorganization (or similar event) of the Borrower, any
other Obligor or otherwise, all as though such payment had not been made.


2.3.  SECTION Guaranty  Absolute,  etc. This Guaranty shall in all respects be a
continuing,  absolute,  unconditional and irrevocable  guaranty of payment,  and
shall remain in full force and effect until the  Termination  Date has occurred.
Each  Guarantor  jointly and severally  guarantees  that the  Obligations of the
Borrower and each other  Obligor will be paid  strictly in  accordance  with the
terms of the Credit  Agreement  and each other Loan  Document  under  which they
arise,  regardless of any law, regulation or order now or hereafter in effect in
any jurisdiction  affecting any of such terms or the rights of any Secured Party
with respect thereto.  The liability of each Guarantor under this Guaranty shall
be joint and several, absolute, unconditional and irrevocable irrespective of:

(a)      any  lack  of  validity,  legality  or  enforceability  of  the  Credit
         Agreement or any other Loan Document;

(b)      the failure of any Secured Party

(i)               to  assert  any claim or  demand  or to  enforce  any right or
                  remedy  against the  Borrower,  any other Obligor or any other
                  Person (including any other guarantor) under the provisions of
                  the Credit Agreement, any other Loan Document or otherwise, or

(ii)              to exercise  any right or remedy  against any other  guarantor
                  (including  each  Guarantor) of, or collateral  securing,  any
                  Obligations;

(c)      any change in the time,  manner or place of payment of, or in any other
         term of, all or any part of the  Obligations,  or any other  extension,
         compromise or renewal of any Obligation;

(d)      any reduction, limitation, impairment or termination of any Obligations
         for any  reason,  including  any claim of waiver,  release,  surrender,
         alteration  or  compromise,  and  shall  not be  subject  to (and  each
         Guarantor  hereby  waives  any  right to or claim  of) any  defense  or
         setoff, counterclaim, recoupment or termination whatsoever by reason of
         the invalidity, illegality,  nongenuineness,  irregularity, compromise,
         unenforceability  of, or any other event or occurrence  affecting,  any
         Obligations or otherwise;

(e)      any amendment to, rescission,  waiver, or other modification of, or any
         consent to or departure from, any of the terms of the Credit  Agreement
         or any other Loan Document;

(f)      any addition,  exchange,  release,  surrender or  non-perfection of any
         collateral, or any amendment to or waiver or release or addition of, or
         consent to or departure  from,  any other  guaranty held by any Secured
         Party securing any of the Obligations; or

(g)      any other  circumstance  which  might  otherwise  constitute  a defense
         available to, or a legal or equitable  discharge of, the Borrower,  any
         other Obligor, any surety or any guarantor.

2.4.  SECTION  Setoff  .  Each  Guarantor  hereby  irrevocably   authorizes  the
Administrative  Agent and each other Secured Party, without the requirement that
any notice be given to such  Guarantor  (such notice being  expressly  waived by
each  Guarantor),  upon the occurrence and during the continuance of any Default
described in clauses (a) through (d) of Section 8.1.9 of the Credit Agreement as
it relates to the Borrower or, with the consent of the  Required  Lenders,  upon
the  occurrence  and during the  continuance  of any other Event of Default,  to
set-off and appropriate and apply to the payment of the Obligations owing to the
Secured Parties (whether or not then due, and whether or not the  Administrative
Agent or such  other  Secured  Party  has made any  demand  for  payment  of the
Obligations),  any and all  balances,  claims,  credits,  deposits  (general  or
special,  time or  demand,  provisional  or  final),  accounts  or money of such
Guarantor  then or  thereafter  maintained  with such Secured  Party;  provided,
however,  that any such  appropriation  and application  shall be subject to the
provisions of Section 4.8 of the Credit Agreement.  Each Secured Party agrees to
notify the  applicable  Guarantor  and the  Administrative  Agent after any such
setoff and application made by such Secured Party;  provided,  however, that the
failure to give such  notice  shall not affect the  validity  of such setoff and
application. The rights of each Secured Party under this Section are in addition
to other rights and remedies  (including other rights of setoff under applicable
law or otherwise) which such Secured Party may have.

2.5. SECTION Waiver,  etc. Each Guarantor hereby waives  promptness,  diligence,
notice of acceptance and any other notice with respect to any of the Obligations
and this Guaranty and any requirement that the Administrative Agent or any other
Secured  Party  protect,  secure,  perfect or insure any Lien,  or any  property
subject  thereto,  or exhaust any right or take any action against the Borrower,
any other Obligor or any other Person  (including any other guarantor) or entity
or any collateral securing the Obligations, as the case may be.

2.6.  SECTION  Postponement of Subrogation,  etc. Each Guarantor  agrees that it
will  not  exercise  any  rights  which  it may  acquire  by way  of  rights  of
subrogation  under this  Guaranty  or any other Loan  Document  to which it is a
party,  nor shall any Guarantor seek or be entitled to seek any  contribution or
reimbursement from the Borrower or any other Obligor,  in respect of any payment
made hereunder,  under any other Loan Document or otherwise, until following the
Termination  Date.  Any  amount  paid to any  Guarantor  on  account of any such
subrogation  rights prior to the Termination Date shall be held in trust for the
benefit of the Secured Parties and shall  immediately be paid and turned over to
the  Administrative  Agent for the benefit of the  Secured  Parties in the exact
form received by such Guarantor  (duly  endorsed in favor of the  Administrative
Agent, if required), to be credited and applied against the Obligations, whether
matured or unmatured, in accordance with Section 2.8; provided, however, that if

(a)      any  Guarantor  has made  payment to the Secured  Parties of all or any
         part of the Obligations; and

(b)      the Termination Date has occurred;

then at such Guarantor's  request,  the Administrative  Agent, (on behalf of the
Secured Parties) will, at the expense of such Guarantor,  execute and deliver to
such   Guarantor   appropriate   documents   (without   recourse   and   without
representation or warranty) necessary to evidence the transfer by subrogation to
such Guarantor of an interest in the Obligations  resulting from such payment by
such  Guarantor.  In  furtherance  of the  foregoing,  at all times prior to the
Termination  Date,  each  Guarantor  shall  refrain  from  taking  any action or
commencing  any  proceeding  against the  Borrower or any other  Obligor (or its
successors  or assigns,  whether in connection  with a bankruptcy  proceeding or
otherwise)  to recover any  amounts in the  respect of payments  made under this
Guaranty to any Secured  Party.  Notwithstanding  the  foregoing,  to the extent
necessary  to toll the  statute of  limitations,  such  Guarantor  may take such
action required to preserve any rights it has by way of rights of subrogation as
consented to by the Administrative Agent in its reasonable discretion.

2.7. SECTION Successors, Transferees and Assigns, etc. This Guaranty shall:

(a)      be binding upon each  Guarantor,  and its  successors,  transferees and
         assigns; and

(b)      inure to the benefit of and be enforceable by the Administrative  Agent
         and each other Secured Party.

Without  limiting  the  generality  of clause  (b),  any  Lender  may  assign or
otherwise transfer (in whole or in part) any Note or Credit Extension held by it
to any other Person and such other Person shall thereupon become vested with all
rights and  benefits in respect  thereof  granted to such Lender  under any Loan
Document  (including  this  Guaranty) or  otherwise,  subject,  however,  to any
contrary  provisions in such  assignment or transfer,  and to the  provisions of
Article X of the Credit Agreement.

2.8.  SECTION  Payments;  Application.  Each  Guarantor  hereby agrees with each
Secured Party as follows:

(a)      Each  Guarantor  agrees  that  all  payments  made  by  such  Guarantor
         hereunder will be made in Dollars to the Administrative  Agent, without
         set-off,  counterclaim or other defense and in accordance with Sections
         4.6 and 4.7 of the  Credit  Agreement,  free and  clear of and  without
         deduction for any Taxes,  the Guarantor  hereby agreeing to comply with
         and be bound by the  provisions  of Sections  4.6 and 4.7 of the Credit
         Agreement  in  respect of all  payments  made by it  hereunder  and the
         provisions of which  Sections are hereby  incorporated  into and made a
         part of  this  Guaranty  by  this  reference  as if set  forth  herein;
         provided,  that  references to the "Borrower" in such Sections shall be
         deemed to be references to each --------  Guarantor,  and references to
         "this Agreement" shall be deemed to be references to this Guaranty.

(b)      All payments made hereunder shall be applied upon receipt as follows:

(i)               first,  to  the  payment  of  all  Obligations  owing  to  the
                  Administrative Agent;

(ii)              second,  after  payment in full of the  amounts  specified  in
                  clause (b)(i), to the ratable payment of all other Obligations
                  owing to the Secured Parties; and

(iii)             third,  after  payment  in full of the  amounts  specified  in
                  clauses  (b)(i) and (b)(ii),  and  following  the  Termination
                  Date, to such Guarantor or any other Person lawfully  entitled
                  to receive such surplus.

         SECTION 2.9.  Acceleration of Guaranty.  Each Guarantor  hereby jointly
and  severally  agrees that,  in the event of an Event of Default  under Section
8.1.9 of the Credit  Agreement,  and if such Default  shall occur at a time when
any of the Obligations may not then be due and payable,  each Guarantor  jointly
and  severally  agrees  that it will pay to the  Administrative  Agent  (for the
benefit of the Secured Parties) forthwith the full amount which would be payable
hereunder by each Guarantor if all such Obligations were then due and payable.

                                   ARTICLE III
                         REPRESENTATIONS AND WARRANTIES

3.1.  SECTION  Representations.  In order to induce the Secured Parties to enter
into the Credit Agreement and make Credit Extensions thereunder,  each Guarantor
represents  and  warrants to each  Secured  Party that the  representations  and
warranties  contained  in  Article VI of the  Credit  Agreement,  insofar as the
representations  and warranties  contained  therein are applicable to it and its
properties,   are  true  and  correct  in  all  material  respects,   each  such
representation  and warranty set forth in such Article (insofar as applicable as
aforesaid)  and all other terms of the Credit  Agreement  to which  reference is
made therein,  together with all related  definitions and ancillary  provisions,
being  hereby  incorporated  into  this  Guaranty  by this  reference  as though
specifically set forth in this Article.  Furthermore,  each Guarantor represents
that it has  knowledge  of the  Borrower's  and each other  Obligor's  financial
condition and affairs and that it has adequate means to obtain from the Borrower
and each other Obligor on an ongoing basis  information  relating thereto and to
the Borrower's and such  Obligor's  ability to pay and perform the  Obligations,
and agrees to assume the  responsibility  for keeping,  and to keep, so informed
for so long as this  Guaranty  is in effect.  Each  Guarantor  acknowledges  and
agrees that the Secured  Parties  shall have no obligation  to  investigate  the
financial  condition or affairs of any Obligor for the benefit of such Guarantor
nor to advise  such  Guarantor  of any fact  respecting,  or any  change in, the
financial  condition or affairs of the Borrower or any other  Obligor that might
become known to any Secured Party at any time, whether or not such Secured Party
knows or believes or has reason to know or believe  that any such fact or change
is unknown to such Guarantor, or might (or does) materially increase the risk of
such Guarantor as guarantor,  or might (or would) affect the willingness of such
Guarantor to continue as a guarantor of the Obligations.


                                   ARTICLE IV
                                 COVENANTS, ETC.

4.1. SECTION Covenants.  Each Guarantor  covenants and agrees that, at all times
prior to the Termination Date, it will perform,  comply with and be bound by all
of the agreements,  covenants and obligations  contained in the Credit Agreement
(including  Article VII thereof)  which are  applicable to such Guarantor or its
properties, each such agreement, covenant and obligation contained in the Credit
Agreement and all other terms of the Credit Agreement to which reference is made
herein,  together with all related definitions and ancillary  provisions,  being
hereby  incorporated into this Guaranty by this reference as though specifically
set forth in this Article.


                                    ARTICLE V

consent of all Lenders.

5.3. SECTION Amendments, etc. No amendment to or waiver of any provision of this
Guaranty,  nor consent to any departure by any Guarantor herefrom,  shall in any

waiver or consent shall be effective  only in the specific  instance and for the
specific purpose for which given.

5.4.  SECTION  Notices.  All  notices  and  other  communications  provided  for

right.  The remedies  herein  provided are  cumulative  and not exclusive of any
remedies provided by law.

                  (b) In the event  that the  Borrower  shall  make,  and/or any
Subordinated  Creditor shall receive from any source whatsoever,  any payment on
Intercompany Debt in contravention of this Subordination  Agreement or the terms

Borrower in the event of

                          (i) any  insolvency or bankruptcy  case or proceeding,
or any  receivership,  liquidation,  reorganization  or  other  similar  case or
proceeding  in  connection  therewith,  relative  to  the  Borrower,  or to  its
creditors, as such, or to its assets,

                          (ii) any liquidation,  dissolution or other winding up
of the Borrower,  whether  voluntary or involuntary and whether or not involving
insolvency or bankruptcy, or

                          (iii) any  assignment  for the benefit of creditors or
any other marshaling of assets and liabilities of the Borrower,

then, and in any such event,  unless the  Administrative  Agent shall  otherwise
agree in  writing,  the  Lenders  shall  receive  payment in cash in full of all
amounts due or to become due  (whether or not the Senior  Indebtedness  has been
declared  due and  payable  prior to the date on which the  Senior  Indebtedness
would  otherwise  have  become due and  payable)  on or in respect of all Senior
Indebtedness   (including   post-petition   interest)  before  the  Subordinated
Creditors or anyone claiming through or on their behalf (including any receiver,
trustee,  or otherwise)  are entitled to receive from any source  whatsoever any

                  (b) If any proceedings, liquidation, dissolution or winding up
referred to in clause (a) above is commenced by or against the Borrower,

                          (i) the Administrative Agent or the Lenders are hereby
irrevocably  authorized  and empowered (in their own names or in the name of the
Borrower  or  otherwise),  but shall have no  obligation,  to  demand,  sue for,
collect and receive every payment or distribution in respect of the Intercompany
Debt above and give acquittance  therefor and to file claims and proofs of claim
and  take  such  other  action  (including,   without  limitation,   voting  the
Intercompany  Debt or  enforcing  any security  interest or other lien  securing
payment of the Intercompany Debt) as the Lenders or the Administrative Agent may
reasonably deem necessary or advisable for the exercise or enforcement of any of
the rights or interests of the Lenders or the  Administrative  Agent  hereunder;
provided  that in the event the  Administrative  Agent or the Lenders  take such
action, the Administrative  Agent or the Lenders shall apply all proceeds first,
to the  payment  of  the  costs  -----  of  enforcement  of  this  Subordination
Agreement,  and  second,  to the pro rata  payment of the ------ --- ---- Senior
Indebtedness; and

                          (ii)  the   Subordinated   Creditors  shall  duly  and
promptly take such action as the Lenders or the Administrative Agent may request
(A) to collect  the  Intercompany  Debt for the  account of the  Lenders and the
Administrative  Agent  and to file  appropriate  claims  or  proofs  of claim in
respect of the  Intercompany  Debt, (B) to execute and deliver to the Lenders or
the  Administrative  Agent  such  powers  of  attorney,  assignments,  or  other
instruments as the Lenders or the Administrative Agent may reasonably request in
order to enable  them to enforce  any and all claims  with  respect  to, and any
security  interests and other liens securing payment of, the  Intercompany  Debt
and (C) to collect and receive any and all payments or  distributions  which may
be payable or deliverable upon or with respect to the Intercompany Debt.

                  (c) All payments from any source  whatsoever or  distributions
of assets of the Borrower,  whether in cash, property or securities upon or with
respect  to the  Intercompany  Debt  which  are  received  by  the  Subordinated
Creditors  contrary to the provisions of this  Subordination  Agreement shall be
received in trust for the pro rata benefit of the Lenders,  shall be  segregated
from other funds and property  held by --- ---- the  Subordinated  Creditors and
shall be forthwith paid over to the Administrative  Agent in the same form as so
received (with any necessary  indorsement) to be applied,  pro rata (in the case
of cash) to, or --- ---- held as collateral (in the case of noncash  property or
securities) for, the payment or prepayment of the Senior  Indebtedness,  whether
matured  or  unmatured,  in  accordance  with the  terms  of this  Subordination
Agreement.

                  (d)  The  Lenders  and the  Administrative  Agent  are  hereby
authorized  to demand  specific  performance  of this  Subordination  Agreement,
whether or not the Borrower or any  Subordinated  Creditor  shall have  complied
with  any of the  provisions  hereof  applicable  to it,  at any  time  when the
Subordinated  Creditors  or any one of them shall have failed to comply with any
of the  provisions  of  this  Subordination  Agreement  applicable  to  it.  The
Subordinated  Creditors  hereby  irrevocably  waive any defense  (other than the
defense of payment in full of the Senior  Indebtedness) based on the adequacy of
a remedy at law which  might be  asserted  as a bar to such  remedy of  specific
performance.

     SECTION  4.  No  Enforcement  or  Commencement  of  Any  Proceedings.  Each
Subordinated  Creditor  agrees that,  so long as any Senior  Indebtedness  shall
remain unpaid,  or any Commitment shall be in effect, it will not accelerate the
maturity of the Intercompany  Debt or commence,  or join with any creditor other
than the  Lenders in  commencing  any  proceeding  referred  to in clause (a) of
Section 3.

     SECTION 5. Rights of Subrogation.  The Subordinated Creditors agree that no
payment or distribution to the Lenders or the  Administrative  Agent pursuant to
the provisions of this  Subordination  Agreement shall entitle the  Subordinated
Creditors to exercise any rights of  subrogation  in respect  thereof  until all
Senior  Indebtedness has been paid in cash in full and the Commitments have been
terminated.  The Subordinated Creditors agree that the subordination  provisions
contained herein shall not be affected by any action,  or failure to act, by the
Administrative  Agent or the Lenders which results, or may result, in affecting,
impairing or  extinguishing  any right of  reimbursement or subrogation or other
right  or  remedy  of  the   Subordinated   Creditors   against  the   Borrower.
Notwithstanding  the foregoing,  to the extent  necessary to toll the statute of
limitations,  the  Subordinated  Creditors  may take  such  action  required  to
preserve any rights they have by way of rights of subrogation as consented to by
the Administrative Agent in its reasonable discretion.

     SECTION 6.  Subordination  Legend;  Further  Assurances.  The  Subordinated
Creditors  and the  Borrower  will  cause  each  note  and  instrument  (if any)
evidencing the Intercompany Debt to be endorsed with the following legend:

                  "The indebtedness evidenced by this instrument is subordinated
         to the prior  payment  in cash in full of the Senior  Indebtedness  (as
         defined in the Intercompany  Subordination Agreement,  dated as of June
         9, 1999) pursuant to, and to the extent  provided in, the  Intercompany
         Subordination  Agreement  by the maker hereof and payee named herein in
         favor of the  Lenders  and any person now or  hereafter  designated  as
         their agent."

Each of the  Subordinated  Creditors and the Borrower  hereby agrees to mark its
books of account in such a manner as shall be effective to give proper notice of
the  effect  of  this  Subordination  Agreement  and  will,  in the  case of any
Intercompany  Debt which is not evidenced by any note or  instrument,  following
the  occurrence  and  subject  to the  continuation  of a  Default  of the  type
described in Section 8.1.1 or 8.1.9 of the Amended and Restated Credit Agreement
or Event of  Default,  upon  the  Administrative  Agent's  request,  cause  such
Intercompany  Debt to be  evidenced  by an  appropriate  note or  instrument  or
instruments  endorsed with the above legend. Each of the Subordinated  Creditors
and the  Borrower  will at its  expense  and at any time  and from  time to time
promptly execute and deliver all further  instruments and documents and take all
further  action that may be necessary or that the Lenders or the  Administrative
Agent may reasonably  request in order to protect any right or interest  granted
or  purported  to  be  granted  hereunder  or  to  enable  the  Lenders  or  the
Administrative   Agent  to  exercise  and  enforce  their  rights  and  remedies
hereunder.

     SECTION  7.  No  Change  in  or  Disposition  of  Intercompany   Debt.  The
Subordinated  Creditors  will not,  without  the prior  written  consent  of the
Administrative Agent:

                  (a)  sell,  assign to any  Person  other  than a  Subordinated
Creditor, transfer, endorse, pledge, encumber or otherwise dispose of any of the
Intercompany Debt;

                  (b)  permit  the terms of any of the  Intercompany  Debt to be
changed in such a manner as to have a material adverse effect upon the rights or
interests of the Lenders or the Administrative Agent; or

                  (c) upon the  occurrence  and during the  continuation  of any
Default of the type  described in Section  8.1.1 or Section 8.1.9 of the Amended
and Restated Credit Agreement or Event of Default,  take, or permit to be taken,
any action to  assert,  collect or  enforce  the  Intercompany  Debt or any part
thereof.

     SECTION 8. Agreement by the Borrower.  The Borrower agrees that it will not
make any payment on any of the Intercompany  Debt, or take any other action,  in
contravention of the provisions of this Subordination Agreement.

     SECTION 9. Obligations  Hereunder Not Affected.  All rights and interest of
the Lenders and the  Administrative  Agent  hereunder,  and all  agreements  and
obligations  of the  Subordinated  Creditors and the Borrower  hereunder,  shall
remain in full force and effect irrespective of:

                  (a) any lack of validity  or  enforceability  of any  document
evidencing Senior Indebtedness;

                  (b) any change in the time,  manner or place of payment of, or
any other term of, all or any of the Senior Indebtedness, or any other amendment
or waiver of or any consent to departure from any of the documents evidencing or
relating to the Senior Indebtedness;

                  (c) any exchange, release or non-perfection of any collateral,
or any  release  or  amendment  or waiver of or consent  to  departure  from any
guaranty or Loan Document, for all or any of the Senior Indebtedness;

                  (d) any failure of any Lender or the  Administrative  Agent to
assert  any claim or to  enforce  any right or remedy  against  any other  party
hereto under the  provisions of this  Subordination  Agreement,  the Amended and
Restated   Credit   Agreement  or  any  other  Loan  Document  other  than  this
Subordination Agreement;

                  (e) any  reduction,  limitation,  impairment or termination of
the Senior  Indebtedness  for any reason  (other  than the defense of payment in
full of the  Senior  Indebtedness),  including  any  claim of  waiver,  release,
surrender,  alteration  or  compromise,  and  shall not be  subject  to (and the
Borrower and each  Subordinated  Creditor hereby waive any right to or claim of)
any  defense  (other  than  the  defense  of  payment  in  full  of  the  Senior
Indebtedness) or setoff,  counterclaim,  recoupment or termination whatsoever by
reason of  invalidity,  illegality,  nongenuineness,  irregularity,  compromise,
unenforceability  of, or any other  event or  occurrence  affecting,  any Senior
Indebtedness; and

                  (f) any other circumstance which might otherwise  constitute a
defense  (other than the defense of payment in full of the Senior  Indebtedness)
available  to,  or a  discharge  of,  the  Borrower  in  respect  of the  Senior
Indebtedness  or the  Subordinated  Creditors  in respect of this  Subordination
Agreement.

This Subordination Agreement shall continue to be effective or be reinstated, as
the case may be, if at any time any payment of any of the Senior Indebtedness is
rescinded  or must  otherwise  be returned  by any Lender or the  Administrative
Agent upon the  insolvency,  bankruptcy  or  reorganization  of the  Borrower or
otherwise,  all as though  such  payment  had not been  made.  The  Subordinated
Creditors  acknowledge and agree that the Lenders and the  Administrative  Agent
may in accordance with the terms of the Amended and Restated  Credit  Agreement,
without  notice or demand and without  affecting or impairing  the  Subordinated
Creditors'  obligations  hereunder,  from  time to time (i)  renew,  compromise,
extend,  increase,  accelerate  or otherwise  change the time for payment of, or
otherwise  change  the terms of the  Senior  Indebtedness  or any part  thereof,
including,  without  limitation,  to increase  or decrease  the rate of interest
thereon or the  principal  amount  thereof;  (ii) take or hold  security for the
payment of the Senior Indebtedness and exchange,  enforce, foreclose upon, waive
and release any such security; (iii) apply such security and direct the order or
manner of sale thereof as the  Administrative  Agent and the  Lenders,  in their
sole  discretion,  may  determine;  (iv)  release  and  substitute  one or  more
endorsers,  warrantors, borrowers or other obligors; and (v) exercise or refrain
from exercising any rights against the Borrower or any other Person.

     SECTION  10.  Representations  and  Warranties.  Each  of the  Subordinated
Creditors,  in respect of itself and the Intercompany  Debt owing to it, and the
Borrower, as the case may be, hereby represents and warrants as follows:

                  (a) the Subordinated  Creditors own the Intercompany  Debt now
outstanding  free and  clear of any Lien  other  than  pursuant  to any  general
security agreement then in effect;

                  (b) this  Subordination  Agreement  constitutes a legal, valid
and  binding  obligation  of  each  Subordinated   Creditor  and  the  Borrower,
enforceable in accordance  with its terms (subject to the effects of bankruptcy,
insolvency, fraudulent conveyance, reorganization,  moratorium and other similar
laws relating to or affecting  creditors'  rights  generally,  general equitable
principles  (whether  considered  in a  proceeding  in  equity or at law) and an
implied covenant of good faith and fair dealing).

     SECTION 11. Amendments, Waivers. No amendment or waiver of any provision of
this  Subordination  Agreement nor consent or any departure by the  Subordinated
Creditors or the Borrower here from,  shall in any event be effective unless the
same shall be in writing  and signed by the  Administrative  Agent and the other
parties  hereto,  and then such waiver,  amendment or consent shall be effective
only in the specific  instance and for the specific purpose for which given. Any
waiver, forbearance, failure or delay by the Administrative Agent or the Lenders
in  exercising,  or the exercise or beginning of exercise by the  Administrative
Agent or the Lenders of, any right, power or remedy, simultaneous or later shall
not preclude the further,  simultaneous  or later  exercise  thereof,  and every
right,  power or  remedy  of the  Administrative  Agent  and the  Lenders  shall
continue  in full  force  and  effect  until  such  right,  power or  remedy  is
specifically waived in a writing executed or authorized by such Lenders.

     SECTION 12. Expenses.  The Subordinated  Creditors and the Borrower jointly
and severally  agree to pay,  upon demand,  to the  Administrative  Agent or the
Lenders,  as applicable,  any and all reasonable costs and expenses,  including,
without  limitation,  reasonable  attorneys'  fees and  disbursements  which the
Lenders or the Administrative Agent may incur in connection with the exercise or
enforcement   of  any  of  the  rights  or   interest  of  the  Lenders  or  the
Administrative Agent hereunder.

     SECTION 13.  Address  for  Notices.  All  notices and other  communications
provided for hereunder shall be in writing (including  facsimile  communication)
and  mailed or  telecopied  or  delivered  to  either  party  hereto,  if to the
Borrower, the Administrative Agent or any Lender, addressed to it at the address
of the Borrower or such Lender or the Administrative  Agent (as the case may be)
listed in the Amended and Restated Credit Agreement or in the Lender  Assignment
Agreement,  as applicable,  and, if to other parties  hereto,  addressed to such
parties in care of the  Borrower  at the  address  specified  in the Amended and
Restated  Credit  Agreement.  All such  notices and other  communications,  when
mailed and properly  addressed with postage prepaid or if properly addressed and

notice or communication, if transmitted by facsimile, shall be deemed given when
the confirmation of transmission thereof is received by the transmitter.

     SECTION 14. Entire Agreement;  Severability.  This Subordination  Agreement
contains  the entire  subordination  agreement  among the  parties  hereto  with
respect  to  the  subject  matter  hereof.  If any of  the  provisions  of  this
Subordination   Agreement   shall  be  held  invalid  or   unenforceable,   this
Subordination   Agreement  shall  be  construed  as  if  not  containing   those
provisions,  and the rights  and  obligations  of the  parties  hereto  shall be
construed and enforced accordingly.

     SECTION  15.  Cumulative  Rights.  The rights,  powers and  remedies of the
Lenders and the Administrative Agent under this Subordination Agreement shall be
in  addition  to all rights,  powers and  remedies  given to the Lenders and the
Administrative  Agent by virtue of any contract,  statute or rule of law, all of
which  rights,  powers and  remedies  shall be  cumulative  and may be exercised
successively or concurrently. The parties hereto expressly acknowledge and agree
that  the  Lenders  and  the  Administrative  Agent  are  intended,  and by this
reference  expressly made,  third party  beneficiaries of the provisions of this
Subordination Agreement.

     SECTION 16. Continuing  Agreement;  Transfer of Notes.  This  Subordination
Agreement is a continuing  agreement of subordination  and the Lenders may, from
time to time and without notice to the Subordinated Creditors,  extend credit to
or make other financial  arrangements with the Borrower in reliance hereon. This
Subordination  Agreement  shall (a) remain in full  force and  effect  until the
Senior  Indebtedness  shall  have been paid in cash in full and all  Commitments
terminated,  (b) be binding upon the  Subordinated  Creditors,  the Borrower and
their  respective  successors,  transferees  and  assigns,  and (c) inure to the
benefit of and be  enforceable by the  Administrative  Agent and each Lender and
their  respective  successors,  transferees  and assigns.  Without  limiting the
generality of the  foregoing,  any Lender may,  subject to the provisions of the
Amended and Restated Credit Agreement,  assign or otherwise  transfer the Senior
Indebtedness  held by it to any other  Person,  subject to Section  10.11 of the
Amended and Restated  Credit  Agreement  and such other  Person shall  thereupon
become  vested  with all the rights in respect  thereof  granted to such  Lender
herein or otherwise.

To:      The Titan Corporation,
           as Borrower

         The Bank of Nova Scotia,
           as Administrative Agent


                              THE TITAN CORPORATION

Gentlemen and Ladies:

         We refer to clause  (d) of Section  10.11.1  of the  Credit  Agreement,
dated as of June 9, 1999 (as  amended,  supplemented,  amended  and  restated or
otherwise modified from time to time, the "Credit  Agreement"),  among The Titan
Corporation,  a Delaware  corporation (the  "Borrower"),  the various  financial
institutions as are or may become parties thereto (collectively, the "Lenders"),
The  Bank  of  Nova  Scotia,  as  administrative  agent  for  the  Lenders  (the
"Administrative  Agent") and  Imperial  Bank,  as  Documentation  Agent.  Unless
otherwise  defined herein or the context otherwise  requires,  terms used herein
have the meanings provided in the Credit Agreement.

         As of ____ __, ____ (the  "Assignment  Date"),  THE BANK OF NOVA SCOTIA
(the "Assignor")  irrevocably  sells,  transfers,  conveys and assigns,  without
recourse,  representation or warranty (except as expressly set forth herein), to
[ASSIGNEE]  (the  "Assignee")  and the Assignee  irrevocably  purchases from the
Assignor that portion of the Loans and Commitments of the Lender as set forth in
Schedule I hereto (the  "Assigned  Portion") so that after giving  effect to the
foregoing   assignment  and  delegation,   the  Assignor's  and  the  Assignee's
Percentages  for the  purposes  of the  Credit  Agreement  and each  other  Loan
Document will be as set forth on Schedule I hereto.

         In addition, this agreement constitutes notice to each of you, pursuant
to clause (c) of Section 10.11.1 of the Credit Agreement,  of the assignment and
delegation to the Assignee of the Assigned Portion of the Credit  Extensions and
Commitments  of the Assignor  outstanding  under the Credit  Agreement as of the
Assignment Date.

         The Assignee shall pay to the Assignor on the Assignment Date an amount
equal to (a) all accrued and unpaid interest on the Assigned Portion and (b) all
accrued and unpaid  commitment  fees payable  under  Section 3.3.1 of the Credit
Agreement with respect to the Assigned  Portion.  In any event,  the Assignee is
entitled to receive  all  payments on account of  interest,  principal  and fees
accrued with  respect to the Assigned  Portion for the period from and after the
Assignment Date.

         The Assignee  hereby  acknowledges  and confirms that it has received a
copy of the Credit  Agreement and the exhibits  related  thereto,  together with
copies of the  documents  which were  required to be delivered  under the Credit
Agreement as a condition to the making of the Credit Extensions thereunder.  The

                  set forth in the Credit Agreement and the other Loan Documents
                  as if it were an original signatory thereto; and

         specified in the second paragraph hereof.

         [The  parties  hereto  understand  that no  processing  fee of the type

law and treaties in effect as of the date hereof, no United States federal taxes
will be required to be withheld by the Administrative Agent or the Borrower with
respect  to any  payments  to be made to the  Assignee  in respect of the Credit
Agreement.

         Notwithstanding  any other  provisions  hereof,  if the consents of the
Borrower and the Administrative  Agent are required under Section 10.11.1 of the
Credit Agreement,  the assignment and delegation  contemplated in this agreement

Exhibit M
Form of Officer's Solvency Certificate
                                                                       EXHIBIT M


                              SOLVENCY CERTIFICATE


         This Certificate (this  "Certificate") is delivered pursuant to Section
5.1.10 of the Amended and Restated  Credit  Agreement,  dated as of June 9, 1999
(as amended, supplemented,  amended and restated or otherwise modified from time
to  time,  the  "Amended  and  Restated  Credit  Agreement"),  among  The  Titan
Corporation,  a Delaware  corporation (the  "Borrower"),  the various  financial
institutions as are, or may from time to time become,  parties thereto (together
with their successors,  transferees,  and assigns,  the "Lenders"),  The Bank of
Nova  Scotia,  as  administrative  agent (the  "Administrative  Agent")  for the
Lenders and Imperial Bank, as  Documentation  Agent.  Unless  otherwise  defined
herein, terms used herein have the meanings provided in the Amended and Restated
Credit Agreement.

         The undersigned  hereby  certifies that [s]he is the [chief  financial]
Authorized Officer of the Borrower (in such capacity,  the "CFO") and that he is
authorized  to execute and deliver this  Certificate  on behalf of the Borrower.
The undersigned further certifies on behalf of the Borrower, that:



<PAGE>

                  (a) The CFO has continued to monitor the  financial  condition
and operations of the Borrower and its  Subsidiaries,  and the CFO has knowledge
of and has participated in the negotiation of the  transactions  contemplated by
the Amended and Restated Credit Agreement and the other Loan Documents.

                  (b) The CFO  and his  staff  are  familiar  with  the  process
through  which the  consolidated  financial  statements  of the Borrower and its
Subsidiaries were generated and prepared.

                  (c) The CFO is familiar with the process through which the Pro
Forma Balance Sheet was generated  and prepared.  In making the  statements  set
forth  in  paragraph  (f)  hereof,  the  CFO  has  considered  the  current  and
anticipated future capital requirements of the Borrower and its Subsidiaries for
the  current  and  future  conduct of the  businesses  of the  Borrower  and its
Subsidiaries.

                  (d)  Based  on the  information  reflected  in the  Pro  Forma
Balance  Sheet and the CFO's  involvement  in the  process  of  collecting  such
information,  the CFO has no reason to believe that the Pro Forma  Balance Sheet
and related financial statements are not

                          (i) a fair  and  reasonable  presentation  of the  pro
forma financial  condition and operations of the Borrower and its  Subsidiaries,
as of the date hereof, on a going-concern basis; and

                          (ii)  a  reasonable   projection   of  the   financial
position,  results  of  operations  and  cash  flows  of the  Borrower  and  its
Subsidiaries

in each case on the  basis of the  assumptions  stated in the Pro Forma  Balance
Sheet, which assumptions the CFO believes to be reasonable.

                  (e) Immediately following the consummation of the transactions
contemplated  by the Amended and Restated  Credit  Agreement  and the other Loan
Documents, the Borrower will be able to pay its Debts (as defined below) as they
become due,  will have assets which will have a "fair  saleable  value"  greater
than its Debts as they become  absolute and matured,  and will have assets which
will have a fair value greater than the sum of all its Debts.

                  (f) Both before and  immediately  after giving  effect to each
transaction  contemplated by the Amended and Restated  Credit  Agreement and the
other Loan Documents,  the Borrower does not have unreasonably small capital and
it is not  engaged  in  businesses  or  transactions,  and  (to  the  best of my
knowledge)  does  not  intend  that it  will be  engaged  in any  businesses  or
transactions, for which it has unreasonably small capital.

                  (g) Both before and  immediately  after giving  effect to each
transaction  contemplated by the Amended and Restated  Credit  Agreement and the
other Loan Documents, the Borrower does not intend to incur, nor believe that it
has incurred, Debts beyond its ability to pay them as they mature.

                  (h) Both before and  immediately  after giving  effect to each
transaction  contemplated by the Amended and Restated Credit  Agreement and each
other Loan Document,  the Borrower has not incurred any obligation  under, or in
connection  therewith,  with actual  intent to hinder,  delay or defraud  either
present or future creditors of the Borrower or any of its Subsidiaries.

                  (i)  For  purposes  hereof,  "Debts"  means  all  liabilities,
obligations,  commitments  and  indebtedness  of any and every  kind and  nature
(including all obligations to trade creditors), whether heretofore or now owing,
arising,  due, or payable by the Borrower to any person and howsoever evidenced,
created,  incurred,  acquired,  or owing,  whether primary,  secondary,  direct,
contingent,  fixed, or otherwise (the foregoing to include,  without limitation,
all  monetary   obligations  arising  under  the  Amended  and  Restated  Credit
Agreement).

                  (j) The "fair  salable  value" of the  Borrower's  assets  and
investments  means the amount which may be realized  within a  reasonable  time,
either through  collection or sale of such  investments  and other assets at the
regular  market  value,  based upon the amount  which could be obtained  for the
property in question  within  such  period by a capable  and  diligent  business
person  from an  interested  buyer who is willing  to  purchase  under  ordinary
selling  conditions.  Although no  determination of the "fair salable value" has
been made, it is my opinion that the asset amounts  reflected  upon the historic
records of the Borrower do not exceed the "fair salable value."

                  (k) The CFO hereby  acknowledges,  on behalf of the  Borrower,
that the  Administrative  Agent and each of the  Lenders  have  relied  upon the
statements  contained  herein and such statements are a material  inducement for
the  Administrative  Agent and each of the Lenders to enter into the Amended and
Restated Credit Agreement and the other Loan Documents.

Notwithstanding  anything to the contrary herein,  the CFO (i) is executing this
Certificate on behalf of the Borrower solely in his representative  capacity and
not in his individual capacity, and (ii) shall not have any liability whatsoever
for any statements,  certifications or representations  made herein,  other than
liability   arising  directly  out  of  his  intentional   misconduct  or  gross
negligence.



<PAGE>


         IN WITNESS  WHEREOF,  the undersigned  Authorized  Officer has executed
this Certificate on this ____ day of June, 1999.

                           TITAN CORPORATION ACQUIRES
                          SYSTEM RESOURCES CORPORATION

      TITAN CONTINUES STRATEGY TO ACQUIRE INFORMATION TECHNOLOGY COMPANIES

                     SYSTEM RESOURCES CORPORATION GENERATED
                         REVENUES OF $63 MILLION IN 1998

San Diego,  June 10, 1999 - The Titan  Corporation  (NYSE:  TTN) announced today
that it has  acquired 100 percent of the stock of System  Resources  Corporation
(SRC) in a  transaction  accounted  for as a  purchase.  SRC,  headquartered  in
Boston,  Massachusetts,  generated  revenue of $63  million  for its fiscal year
ended  September 30, 1998.  The  acquisition  will be financed by Titan's credit
facilities. The specific terms of the acquisition were not disclosed.

         System  Resources   Corporation,   founded  in  1985,  has  experienced
continued  growth as a provider of  information  systems  solutions and services
including   complex,   high-end   customized   systems  utilizing  leading  edge
technologies.  SRC's  business base  principally  includes  aviation and airport
systems,  security,  logistics  automation,  and command and control.  SRC has a
diverse  range of clients  within the  Department of Defense,  Federal  Aviation
Administration,   other  federal  agencies,  state  governments  and  commercial
organizations.  SRC employs  approximately 600 people based in ten U.S. offices.
Samir  A.  Desai,  founder  and  Chief  Executive  Officer  of SRC will act as a
consultant to Titan.

         Commenting on the  acquisition,  Titan's  President and Chief Executive
Officer,  Gene W. Ray said,  "We are very  excited that SRC has joined the Titan
family.  Not only has SRC  experienced  a growth  rate of over 20 percent  since
1996, SRC also brings additional  significant  information technology capability
to Titan,  particularly in the security and  intelligence  areas. Ray went on to
say, "The  integration of SRC and Titan is expected to be very smooth due to the
similar  customer  base  and  geographic  location  of  operations  of  the  two
companies." Ray concluded, "With the acquisition of SRC, Titan's core government
information technology business is nearly one third of a billion dollars in size
on an annualized  revenue run rate basis.  Through  internal  growth and further
acquisitions,  we remain  committed to building a billion dollar business in the
Defense Information Technology area over the next several years."

         The  Titan   Corporation  is  a  leading  provider  and  integrator  of
state-of-the-art  information technology,  satellite  communications systems and
services, and medical product sterilization and food pasteurization products and
services. In addition to maximizing internal growth, Titan employs a strategy of
acquiring  businesses  that can be readily  integrated  into its  existing  core
businesses in order to increase  profitability  and grow market share.  The firm
has annualized sales in excess of $400 million with a total backlog of more than
$1.0 billion and has 2,800 employees.  Titan Corporation is headquartered in San
Diego, CA.
