                              THE TITAN CORPORATION
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  JUNE 30, 1998

              (Dollar amounts in thousands, except per share data)

NOTE (1)  BASIS OF FINANCIAL STATEMENT PREPARATION

The accompanying consolidated financial information of The Titan Corporation 
and its subsidiaries ("the Company" or "Titan") should be read in conjunction 
with the Notes to Consolidated Financial Statements contained in the 
Company's Annual Report on Form 10-K/A to the Securities and Exchange 
Commission for the year ended December 31, 1997 and DBA Systems, Inc.'s 
("DBA") Annual Report on Form 10-K for the year ended June 30, 1997. The 
accompanying financial information includes all subsidiaries on a 
consolidated basis and all normal recurring adjustments which are considered 
necessary by the Company's management for a fair presentation of the 
financial position and results of operations for the periods presented. 
However, these results are not necessarily indicative of results for a full 
year. The prior year financial statements have been restated to reflect two 
mergers in 1998 (see Note 2) and the discontinuance of certain operations in 
1997 (see Note 3). Additionally, certain prior year amounts have been 
reclassified to conform to the 1998 presentation.

The preparation of financial statements in conformity with generally accepted 
accounting principles requires management to make estimates and assumptions 
that affect the reported amounts of assets and liabilities and disclosure of 
contingent assets and liabilities at the date of the financial statements and 
the reported amounts of revenues and expenses during the reporting period. 
Actual results could differ from those estimates.

NEW ACCOUNTING STANDARDS. In January 1998, the Company adopted Statement of 
Financial Accounting Standards No. 130, "Reporting Comprehensive Income" 
("SFAS 130"). This Statement establishes standards for reporting and display 
of comprehensive income and its components in a full set of general purpose 
financial statements. The objective of the Statement is to report a measure 
of all changes in equity of an enterprise that result from transactions and 
other economic events of the period other than transactions with owners 
("comprehensive income"). Comprehensive income is the total of net income and 
all other nonowner changes in equity. The adoption of the accounting and 
disclosure provisions of SFAS 130 has had no material impact on the Company's 
financial statements and results of operations, as comprehensive income is 
the same as net income for all periods presented herein.

In March 1998, the Company adopted Statement of Financial Accounting 
Standards No. 132, "Employers' Disclosures about Pensions and Other 
Postretirement Benefits" ("SFAS 132"). This statement revises and 
standardizes employers' disclosures about pension and other postretirement 
benefit plans, but it does not change the measurement or recognition of those 
plans. This Statement further requires restatement of disclosure provisions 
for earlier periods provided for comparative purposes. The adoption of SFAS 
132 has had no material impact on the Company's financial statements or 
related disclosures thereto.

In March 1998, the Accounting Standards Executive Committee issued AICPA 
Statement of Position 98-1, "Accounting for the Costs of Computer Software 
Developed or Obtained for Internal Use" ("SOP 98-

                                        6

<PAGE>

1"). This Statement provides guidance on accounting for the costs of computer 
software developed or obtained for internal use and identifies 
characteristics of internal-use software as well as assists in determining 
when computer software is for internal use. SOP 98-1 is effective for fiscal 
years beginning after December 15, 1998, with earlier application permitted. 
The Company has not yet determined what impact, if any, the adoption of the 
accounting and disclosure provisions of SOP 98-1 will have on the Company's 
financial statements, results of operations or related disclosures thereto.

In April 1998, the Accounting Standards Executive Committee issued AICPA 
Statement of Position 98-5, "Reporting on the Costs of Start-Up Activities" 
("SOP 98-5"). This Statement provides guidance on the financial reporting of 
start-up costs and organization costs and requires that such costs of 
start-up activities be expensed as incurred. SOP 98-5 is effective for fiscal 
years beginning after December 15, 1998, with earlier application permitted. 
The Company expects to adopt the provisions of SOP 98-5, which will result in 
a charge to be reported as a cumulative effect of a change in accounting 
principle. Management believes that the adoption of this bulletin may result 
in a significant non-cash charge. However, management has not yet determined 
what impact the adoption of this bulletin will have on net income.

NOTE (2)  MERGERS AND ACQUISITION

On June 30, 1998, the Company consummated a merger with Horizons Technology, 
Inc. ("Horizons"), a Delaware corporation, in a stock-for-stock transaction. 
Horizons is a provider of systems engineering and program management 
services, computer systems integration and high-end software and has become 
part of Titan's Information Technologies segment. Titan issued approximately 
3,200,000 shares of common stock in exchange for all the outstanding shares 
of Horizons stock based on exchange ratios of approximately .37 and .82 
shares of Titan's common stock for each share of Horizons' common stock and 
Horizons' preferred stock, respectively. The merger constituted a tax-free 
reorganization and has been accounted for as a pooling of interests.

On February 27, 1998, the Company consummated a merger with DBA Systems, Inc. 
("DBA"), a Florida Corporation, in a stock-for-stock transaction. DBA is a 
developer and manufacturer of digital imaging products, electro-optical 
systems and threat simulation/training systems. DBA's products and systems 
are primarily used by the defense and intelligence communities; accordingly, 
it is included in Titan's Information Technologies segment. Titan issued 
approximately 6,100,000 shares of common stock for all the outstanding shares 
of DBA stock based on an exchange ratio of approximately 1.37 shares of Titan 
common stock for each share of DBA stock. The special charges of $1,460 in 
the six months ended June 30, 1998, primarily represent the costs and 
expenses related to this merger. The merger constituted a tax-free 
reorganization and has been accounted for as a pooling of interests.

In connection with its acquisition of DBA, Titan acquired land and a building 
which are included in other non-current assets. DBA recorded a $2.0 million 
charge in its quarter ended September 30, 1997 to recognize an impairment in 
the value of this asset. Management is actively marketing the property for 
sale through various channels and believes that the carrying value of this 
asset, as reflected in the accompanying financial statements for the quarter 
ended June 30, 1998, is stated at an amount that is fully recoverable.

DBA also recorded a $3.0 million charge in the quarter ended September 30, 
1997, in recognition of certain environmental matters at its 

                                        7

<PAGE>

Kissimmee facility including, but not limited to, soil contamination and 
potential asbestos and lead based paint contamination. These matters became 
known to DBA as a result of an environmental study performed as part of 
Titan's acquisition due diligence process. The accrual has been recorded in 
accordance with SFAS No. 5 and SOP 96-1 and represents an initial estimate 
which could change significantly as further studies are performed. In the 
accompanying balance sheet, approximately $.2 million is included in other 
current liabilities and the remaining $2.8 million is included in other 
non-current liabilities based on the estimated timing of continued 
assessments and remediation work to be performed. The Company had commenced 
its pre cleanup activities which are expected to continue through at least 
fiscal 1998.

Also, concurrent with this acquisition, DBA recorded certain charges, in 
addition to those noted above, aggregating to $4.8 million, relating to the 
write down of certain assets to estimated net realizable value in the quarter 
ended December 31, 1997.

Effective January 1, 1998, Horizons' January 31 and DBA's June 30 fiscal 
year-ends have been changed to coincide with the Company's year-end. The 1997 
financial statements presented have been restated to include the combined 
results of operations, financial position and cash flows of Horizons and DBA 
as if the mergers had occurred at the beginning of the periods presented.

The combining periods of Titan, DBA and Horizons are as follows:

A pooling of interests adjustment has been made in the consolidated 
statements of cash flows and consolidated statements of stockholders' equity 
for the six months ended June 30, 1997 to reflect the activity for DBA in the 
six months ended December 31, 1996, as reported in DBA's Form 10-Q for the 
fiscal quarter ended December 31, 1996. The pooling of interests adjustments 
in the consolidated statements of cash flows and consolidated statements of 
stockholders' equity for the six months ended June 30, 1998, reflect the 
activity for Horizons for the month ended January 31, 1998, included in 
Titan's results of operations in both the year ended December 31, 1997, and 
the six months ended June 30, 1998. Revenues from continuing operations for 
Horizons for January 1998 were $2,032.

million in cash, and notes payable to the shareholders of Validity totaling 
$3 million, subject to post-closing adjustments, if any, due and payable 
March 31, 1999, and bearing interest at the prime rate. The transaction has 
been accounted for as a purchase; accordingly, the consolidated balance sheet 
includes Validity as of June 30, 1998. The excess of the purchase price over 
the estimated fair value of net assets acquired, to be amortized on a 
straight-line basis over 30 years, was approximately $18.9 million as of June 
30, 1998, based on net assets acquired of $560. Validity's results of 
operations have been consolidated with the Company's results of operations 
beginning April 1, 1998.

NOTE (3)  DISCONTINUED OPERATIONS

In April 1997, the Company's Board of Directors adopted a plan to divest the 
Company's broadband communications business. The results of the broadband 
communications business have been accounted for as a discontinued operation 
in accordance with Accounting Principles Board Opinion No. 30, which among 
other provisions, anticipates that the plan of disposal will be carried out 
within one year. Management has identified several potential strategic 
investors with whom it is presently involved in negotiations for the sale of 
all or part of the business and/or technology of the broadband communications 
business. Concurrently, Titan continues to search for other potential 
investors. During the first quarter of 1998, the Company received 
approximately $2,600 as settlement of certain contingencies related to the 
broadband patents and intangibles as well as initial payments related to 
licensing the technology. These proceeds were applied to net current assets 
of discontinued operations. The Company hopes to receive additional cash 
proceeds, amounts of which cannot be presently determined, through September 
30, 1998, at which time management expects to have adequate information to 
determine the ultimate realizability of the net assets of this discontinued 
operation.

Revenues for the broadband communications business were $47 and $5 for the 
three months and $47 and $529 for the six months ended June 30, 1998 and 
1997, respectively. Included in the loss from discontinued operation of $343 
is a tax benefit of $177 for the six months ended June 30, 1997. The Company 
deferred losses from the discontinued operation of $9,721 in fiscal year 1997 
and $661 and $3,951 in the three and six months ended June 30, 1998, 
respectively, which 

                                        9

<PAGE>

primarily represented amortization costs of intangible assets, and to a 
lesser extent, certain wind-down costs of the business. Included in the 
deferred losses is interest of $90 and $190 in the three and six months ended 
June 30, 1998, respectively, allocated to the discontinued operation based on 
the ratio of net assets to be sold to the sum of total net assets of the 
Company. Net current assets of the discontinued operation consist primarily 
of accounts receivable, inventory, and cummulative deferred losses from the 
date of discontinuance net of accounts payable, accrued compensation and 
other current liabilities. Net noncurrent assets of discontinued operation 
consist primarily of property and equipment.

In December 1997, the Horizons' Board of Directors adopted a plan to wind 
down and exit its commercial software business (Information Systems segment 
or "ISG"), in order to focus entirely on its profitable government 
information technologies business or Systems Engineering segment. 
Accordingly, the Information Systems segment has been accounted for as a 
discontinued operation for all periods presented in accordance with 
Accounting Principles Board Opinion No. 30 (APB 30), which among other 
provisions, anticipates that the plan of disposal will be carried out within 
one year.

In the fourth quarter of 1997, the Company recorded a charge of approximately 
$3,600 for costs to be incurred in future periods in connection with the 
winding down of this operation. Net current liabilities of discontinued 
operations consist primarily of accrued facility costs, warranties, and 
anticipated operating losses from the date of discontinuance until the 
estimated disposal date net of certain accounts receivable balances. Prior 
year restated combined financial statements reflect the ISG business as a 
discontinued operation. Revenues for the ISG business were $683 and $800 for 
the three months and $1,299 and $1,565 for the six months ended June 30, 1998 
and 1997, respectively. Losses from ISG applied to the deferred charge were 
$946 and $1,601 in the three and six month periods ended June 30, 1998, 
respectively. Included in the losses of $262 and $753 from discontinued 
operations are tax benefits of $75 and $216 for the three and six months 
ended June 30, 1997, respectively.

NOTE (4)  DEBT

In March 1998, the Company's line of credit agreement was amended to increase 
the available credit to $30,000 and extend the maturity date to June 30, 
1999. At June 30, 1998, borrowings outstanding under the line of credit were 
$20,800, at a weighted average interest rate of 7.89% and commitments under 
letters of credit under this agreement were $1,081. At June 30, 1998, 
Horizons had $5,537 outstanding under a line of credit at an interest rate of 
10.5%. At June 30, 1998, the Company was in compliance with all financial 
covenants under its various debt agreements.

On July 29, 1998, the Company entered into a credit agreement with a bank 
syndicate under which it may borrow up to $80 million. The credit facility 
includes a five year $55 million working capital line of credit and a one 
year $25 million component dedicated for acquisitions which converts any 
outstanding balances after one year into a term loan, to be repaid in 
increasing quarterly amounts over four years. The Company has the option to 
borrow at the bank base rate or at LIBOR, plus applicable margins based on 
the ratio of total debt to EBITDA (earnings before interest, taxes, 
depreciation and amortization). The agreement contains, among other financial 
covenants, provisions which set maximum debt to EBITDA limits and which 
require the Company to maintain stipulated levels of EBITDA, tangible net 
worth, a minimum quick ratio, and minimum coverage of fixed charges, as 
defined. Initial proceeds of $36.1 million were used 

                                        10

to pay off and replace the outstanding line of credit balances with Titan's 
and Horizons' banks and for working capital purposes.

In the three and six months ended June 30, 1998, respectively, options to 
purchase 277,100 and 279,800 shares of common stock at prices ranging from 
$7.00 to $9.50 and $6.69 to $9.50 per share were not included in the 
computation of diluted EPS, as the exercise price of such options was greater 
than the average market price of the common shares. Similarly, in the three 
and six months ended June 30, 1997, respectively, options to purchase 
1,045,500 and 1,302,900 shares of common stock at prices ranging from $3.63 
to $9.50 and $3.58 to $9.50 were not included in the computation of EPS. In 
the six months ended June 30, 1998, 9,121,200 shares of common stock that 
could result from the conversion of the Company's convertible subordinated 
debentures were not included in the computation of diluted EPS, as the effect 
would have been anti-dilutive. In all periods in both 1998 and 1997, 463,248 
shares of common stock that could result from the conversion of cumulative 
convertible preferred stock were not included in the computation of diluted 
EPS, as the effect would have been anti-dilutive.

In 1998 and 1997, 333,333 common shares that could result from the conversion 
of Series B Cumulative Convertible Redeemable Preferred Stock were not 
included in the computation of diluted EPS, as the effect would have been 
anti-dilutive. In June 1998, the Company redeemed 416,667 shares of this 
stock at $6.00 per share. In July 1998, the Company redeemed the remainder of 
this stock. Also anti-dilutive in the six months ended June 30, 1997, were 
warrants outstanding for 100,000 common shares. The warrants were exercised 
in June 1998.

NOTE (6)  COMMITMENTS AND CONTINGENCIES

On April 19, 1995, the Company was served in a lawsuit entitled DONALD P. 
SHAW V. TITAN CORPORATION (the "Lawsuit"). The Lawsuit was pending in the 
United States District Court for the Eastern District of Virginia, Alexandria 
Division, and sought compensatory damages in an aggregate amount of 
$3,000,000 and punitive damages in the amount of $1,050,000 on account of 
alleged wrongful termination and intentional infliction of emotional 
distress. The Lawsuit resulted in a verdict for the plaintiff awarding 
$65,000 in compensatory damages and $350,000 in punitive damages which was 
affirmed on appeal in February 1998, and was paid in June 1998. The outcome 
of the Lawsuit did not have a material adverse effect on the financial 
position or results of operations of the Company.

NOTE (7)  SUBSEQUENT EVENTS

On July 1, 1998, the Company entered into a definitive merger agreement with 
Delfin Systems ("Delfin"), a California corporation, whereby, if approved by 
the stockholders of Delfin, Delfin will become a wholly-owned subsidiary of 
The Titan Corporation in a stock-for-stock transaction. On August 7, 1998, 
Titan entered into a definitive agreement with VisiCom Laboratories, Inc., a 
California corporation, whereby, if approved by the stockholders of VisiCom, 
VisiCom will become a wholly-owned subsidiary of The Titan Corporation in a 
stock-for-stock transaction. Both acquisitions will be accounted for as 
poolings of interests.

                              THE TITAN CORPORATION


           ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF
                       OPERATIONS AND FINANCIAL CONDITION

                          (Dollar amounts in thousands,
                             except per share data)


RESULTS OF OPERATIONS

Consolidated results:

Revenues for the second quarter of 1998 increased from $56,511 in the second 
quarter of 1997 to $58,815. Revenues for the six months ended June 30 were 
$108,783 and $112,729 in 1998 and 1997, respectively. In both the second 
quarter and six months ended June 30, 1998 compared to the corresponding 
periods of 1997, the Medical Sterilization and Food Pasteurization segment 
reported increased revenues and operating income. The Company reported net 
income of $2,533 and $3,169 for the second quarter and six months of 1998 
compared to $1,480 and $2,767 for the second quarter and six months of 1997. 
Included in the six months ended June 30, 1998 is a special pre-tax charge 
for merger related expenses of $1,460. Included in the second quarter and six 
months of 1997 is a loss from discontinued operations of $262 and $1,096, 
respectively. The Company recorded a deferred loss from certain of the 
discontinued operations of $661 and $3,951 in the quarter and six months 
ended June 30, 1998, respectively, which primarily represented amortization 
costs of intangible assets, and to a lesser degree, wind-down costs of that 
business. Income from continuing operations in the second quarter and six 
months of 1998 was $2,533 and $3,169, compared to $1,742 and $3,863 in the 
second quarter and six months of 1997. This difference was primarily due to 
the impact of the changes in revenues noted above, as well as the impact of 
the special merger related expenses in 1998.

Selling, general and administrative expense ("SG&A") as a percentage of 
revenue decreased from 14% in the second quarter of 1997 to 10% for the same 
period in 1998, and from 13% in the six months of 1996 to 12% for the same 
period in 1997. These decreases were due primarily to the impact of ongoing 
cost reduction measures taken across all business segments. Research and 
development costs (R&D) decreased overall from $2,005 in the second quarter 
of 1997 to $994 for the same period in 1998, and from $3,630 for the six 
months of 1997 to $2,512 for the same period in 1998. This change was 
primarily due to the completion of certain development and certification 
efforts in the Communications Systems segment in early 1998.

Net interest expense increased $327 and $417 in the second quarter and six 
months ended June 30, 1998 compared to the comparable periods of 1997, 
primarily from interest related to increased borrowings on the Company's line 
of credit.

The income tax provision is a 33% and 34% effective rate in the second 
quarter and six months of 1998 compared to a 42% and 36% effective rate in 
the second quarter and six months of 1997, respectively. These effective 
rates approximate the expected combined federal and state statutory rates, 
less expected credits, primarily R&D credits.

Business Segments:

THREE MONTHS ENDED JUNE 30, 1998 AND 1997:

In the Information Technologies segment, revenues grew $2,890, from $36,128 
in the second quarter of 1997 to $39,018 in the second quarter of 1998. The 
increase in revenues is principally due to the revenues generated by the 
acquired business Validity, which was acquired in March 1998. Operating 
income increased $442 from $4,689 in the second quarter of 1997 to $5,131 in 
the second quarter of 1998, primarily reflecting the impact of the increased 
revenues. Furthermore, 1998 and 1997 revenue and operating income include 
non-recurring credits resulting from the reevaluation of estimates of certain 
allowable contract costs based upon favorable developments with certain 
government agencies.

Revenues in the Communications Systems segment decreased $1,624 from $12,501 
in the second quarter of 1997 to $10,877 in the second quarter of 1998, due 
to decreased shipments made on the Company's contract with PT. Pasifik 
Satelit Nusantara (PSN) to provide rural telephony terminals for a system in 
Indonesia. This was partially offset by increased revenues recorded on the 
Company's Mini-DAMA production contract. Operating performance for this 
segment improved from an operating loss of $564 in the second quarter of 1997 
to operating income of $316 in the second quarter of 1998, principally due to 
increased margins, as well as the winding down from 1997 to 1998 of 
significant development and certification efforts.

The commercial satellite communications business accounted for approximately 
$1,205 of the Communications Systems segment revenues generated in the second 
quarter of 1998. The commercial satellite communications business provides 
Xpress Connection terminals to PSN as well as the ground segment for the 
multi media Asia (M2A) project. The ongoing economic and political turmoil in 
Asia could result in a material and adverse impact on this segment's revenues 
and operating results for the remainder of 1998.

Software Systems segment revenues increased $326 from $3,857 in the second 
quarter of 1997 to $4,183 in the second quarter of 1998, primarily due to 
work performed on contracts with certain new customers in this business. The 
increase in operating income of $411 from $653 of operating income in the 
second quarter of 1997 to $1,064 in the second quarter of 1998 was 
principally due to increased revenues and the impact of cost reductions made 
by the Company during 1997.

Revenues and operating performance in the Medical Sterilization and Food 
Pasteurization segment improved from $1,484 and $4 in the second quarter of 
1997 to $3,221 and $432 in the second quarter of 1998, respectively. This 
improvement primarily relates to work being performed on contracts to provide 
in-house SureBeam sterilization systems.

In the Emerging Technologies segment, revenues declined $1,025 from $2,541 in 
the second quarter of 1997 to $1,516 in the second quarter of 1998 primarily 
due to the wind down of the Company's environmental consulting business 
during the first quarter of 1998 and due to the near completion of certain of 
the Company's contracts to build linear electron accelerators.

SIX MONTHS ENDED JUNE 30, 1998 AND 1997:

In the Information Technologies segment, revenues and operating income 
declined from $72,977 and $8,748 in the six months ended June 30, 1997 to 
$70,495 and $7,696 in the six months ended June 30, 1998. The decline in 
revenues was primarily due to the redeployment of Department of Defense 
("DOD") funding appropriations, which impacted certain work the Company 
performs for the U.S. Navy and due to a change in revenue mix to a more labor 
intensive mix compared to a more material intensive mix. The decline in 
operating performance was primarily due to the impact of the special 
acquisition related charges of $1,460 in 1998.

Revenues for the Communications Systems segment decreased $751 from $23,526 
in the six months ended June 30, 1997 to $22,775 in the six months ended June 
30, 1998, due primarily to the decreased shipments made on the Company's 
contract for a rural telephony system in Indonesia noted above. Segment 
operating performance improved $1,545 from an operating loss of $433 in the 
six months ended June 30, 1997 to operating income of $1,112 in the six 
months ended June 30, 1998. This improvement reflects the wind-down of 
significant development and certification expenditures incurred in the prior 
year.

Software Systems segment revenues decreased $222 from $7,896 in the six 
months ended June 30, 1997 to $7,674 in the six months ended June 30, 1998, 
however operating income increased $284 from $1,428 in the six months ended 
June 30, 1997 to $1,712 in the six months ended June 30, 1998. The increase 
in operating income resulted primarily from the impact of cost reduction 
measures taken by the Company in 1997.

Revenues and operating performance in the Medical Sterilization and Food 
Pasteurization segment improved from revenues of $2,629 and an operating loss 
of $22 in the six months ended June 30, 1997 to revenue of $5,168 and 
operating income of $640 in the six months ended June 30, 1998. This 
improvement primarily relates to work being performed on contracts to provide 
in-house SureBeam sterilization systems.

The Emerging Technologies segment revenues and operating performance declined 
from revenue and operating income of $5,701 and $254 in the six months of 
1997 to revenue and an operating loss of $2,671 and $431 in the six months of 
1998. This decline is primarily due to the wind down of the Company's 
environmental consulting business during the first quarter of 1998 and 
reduced margins related to wind-down costs incurred on certain of the 
Company's contracts to build linear electron accelerators.

LIQUIDITY AND CAPITAL RESOURCES

During the six months ended June 30, 1998, Titan used $4,502 for operating 
requirements. Significant cash uses include an increase in accounts 
receivable balances of $8,849 primarily in the Information Technologies and 
Communications Systems segments, an increase in inventories of $3,252 
primarily related to government satellite communications and commercial rural 
telephony products, and the funding requirements for acquisition related 
charges of $1,460, accrued compensation obligations of $1,279 and other 
accrued obligations of $627.

Approximately $2,700 and $2,000 of the increase in receivables and inventory, 
respectively, is related to the commercial satellite communications business. 
Titan's aggregate investment in the commercial satellite communications 
business is reflected in the balance sheet primarily within the captions of 
Accounts Receivable, Inventories, and Property and Equipment and aggregates 
approximately $20,100 at June 30, 1998. The Company has negotiated a payment 
plan with its customer PSN for settlement of all amounts due from PSN, 
whereby PSN will make monthly installments over the next 15 months, with a 
balloon payment at the end of the term. In the event that PSN obtains 
financing from additional sources, the payment terms will be renegotiated at 
that time. The Company is continually assessing the impact of the recent 
events in Asia, including the currency devaluation in Indonesia, Malaysia, 
Taiwan and the Philippines, on its Communications Systems segment, and 
presently does not believe that there has been any significant impairment in 
its aggregate investment, as mentioned above, or in the segment's business.

Cash of $11,679, net of cash acquired, was used for the Company's acquisition 
of Validity Corporation. Cash was provided primarily by the Company's lines 
of credit ($8,660) and by the sale of investments ($4,499). On July 29, 1998, 
the Company entered into a credit agreement with a bank syndicate under which 
it may borrow up to $80 million. The credit facility includes a five year $55 
million working capital line of credit and a one year $25 million component 
dedicated for acquisitions which converts any outstanding balances after one 
year into a term loan, to be repaid in increasing quarterly amounts over four 
years. The Company has the option to borrow at the bank base rate or at 
LIBOR, plus applicable margins based on the ratio of total debt to EBITDA 
(earnings before interest, taxes, depreciation and amortization). The 
agreement contains, among other financial covenants, provisions which set 
maximum debt to EBITDA limits and which require the Company to maintain 
stipulated levels of EBITDA, tangible net worth, a minimum quick ratio, and 
minimum coverage of fixed charges, as defined. Initial proceeds of $36.1 
million were used to pay off and replace the outstanding line of credit 
balances with Titan's and Horizons' banks and for working capital purposes.

Funding for the advancement of the Company's strategic goals, including 
acquisitions and continued investment in targeted commercial businesses and 
start-up ventures, is expected to continue throughout 1998. The Company plans 
to finance these requirements from a combination of sources, which include 
cash generation from the Company's core businesses and the expansion of the 
Company's bank line of credit as described above. Furthermore, the Company 
anticipates selling the assets of its broadband communications business in 
1998, and is also exploring several equity alternatives as potential sources 

                                        17

of capital. One of Titan's primary strategies is the funding of growth in 
specific subsidiaries through spin-out transactions. If Titan is unable to 
implement this strategy, whether in whole or in part, then the Company may 
need to complete additional equity or debt financings to fund the continued 
expansion of its operations and potential acquisitions of new technologies. 
Any additional equity or convertible debt financings could, however, result 
in substantial dilution to the Company's stockholders. Management is 
continually monitoring and reevaluating its level of investment in all of its 
operations and the financing sources available to achieve the Company's goals 
in each business area.

The Company has a 141,000 square foot manufacturing facility in Kissimmee, 
Florida which was obtained in the acquisition of DBA. The property has been 
held for sale since June 1996. A charge was recorded by DBA in the quarter 
ended December 31, 1997 to adjust the carrying value of the property to 
estimated fair market value. Management continues to actively market the 
property and regularly reviews it for further impairment. Management believes 
that the recorded value of the property continues to approximate estimated 
fair market value.

DBA also recorded a $3.0 million charge in the quarter ended September 30, 
1997 in recognition of certain environmental matters including, but not 
limited to soil contamination and potential asbestos and lead based paint 
contamination at the Company's Kissimmee, Florida facility. These matters 
became known to DBA as a result of a limited environmental study performed as 
part of Titan's acquisition due diligence process. The accrual has been 
recorded in accordance with SFAS No. 5 and SOP 96-1 and represents an initial 
estimate which could change significantly as further studies are performed. 
In the accompanying balance sheet, approximately $.2 million is included in 
other current liabilities and the remaining $2.8 million is included in other 
non-current liabilities based on the estimated timing of remediation work to 
be performed. The Company has commenced its pre cleanup activities, which are 
expected to continue through at least fiscal 1998.

HOWEVER, that all initial Loans shall be made as Base Rate Loans.  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


                                     -32-

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 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.

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

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


                                     -33-

<PAGE>

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, 
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


                                     -34-

<PAGE>

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 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.

                                     -35-

<PAGE>


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.

     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


                                     -36-

<PAGE>

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 be rebuttably presumptive evidence of the 
accuracy of the information so set forth; PROVIDED, HOWEVER, that the failure 
of any Lender to make any such notations shall not limit or otherwise affect 
any Obligations of any Obligor.

                      REPAYMENTS, PREPAYMENTS, INTEREST AND FEES

     SECTION 3.1.  REPAYMENTS AND PREPAYMENTS; APPLICATION.

     SECTION 3.1.1.  REPAYMENTS AND PREPAYMENTS.  The Borrower shall repay in
full the unpaid principal amount of each Loan upon the applicable Stated
Maturity Date therefor.  Prior thereto, payments and prepayments of Loans shall
or may be made as set forth below.

          (a) From time to time on any Business Day, the Borrower may make a
     voluntary prepayment, in whole or in part, of the outstanding principal
     amount of any:

               (i) Loans (other than Swing Line Loans), PROVIDED, HOWEVER, that

                    (A)  any such prepayment of the Term Loan shall be applied
               to the remaining amortization payments, for the Term Loan as
               provided for in SECTION 3.1.1(d) and any such prepayment of
               Revolving Loans shall be made PRO RATA among the Revolving Loans
               of the same type and, if applicable, having the same Interest
               Period of all Lenders that have made such Revolving Loans;

                    (B)  all such voluntary prepayments shall require at least
               one but no more than five Business Days' prior written notice to
               the Administrative Agent; and

                    (C)  all such voluntary partial prepayments shall be, in the
               case of LIBO Rate Loans, in an aggregate minimum amount of
               $1,000,000 and an integral multiple of $1,000,000 and, in the
               case of Base Rate Loans, in an aggregate minimum amount of
               $500,000 and an integral multiple of $100,000; and

               (ii) Swing Line Loans, PROVIDED that

                    (A)  all such voluntary prepayments shall require prior
               telephonic notice to Scotiabank on or before 1:00 p.m., New York
               time, on the day of such prepayment (such notice to be confirmed
               in writing within 24 hours thereafter); and

                                     -37-

<PAGE>


                    (B)  all such voluntary partial prepayments shall be in an
               aggregate minimum amount of $200,000 and an integral multiple of
               $100,000.

          (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 and SECTION 3.1.2), 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.

          (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 such 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.

          (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 the
     Term Loans, if any, in an amount equal to the amount set forth below:

     Loans is so accelerated (in which case the portion so accelerated shall be
     so repaid).

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.

          (a) Subject to CLAUSE (b), each prepayment or repayment of the
     principal of the Loans shall be applied, to the extent of such 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 prepaid
     subject to the provisions of SECTION 4.4 (together with a payment of all
     accrued interest).

          (b) Each prepayment of Loans made pursuant to CLAUSE (c) of SECTION
     3.1.1 shall be applied (i) FIRST, (A) prior to the Conversion Date, to the
     mandatory prepayment of the outstanding principal amount of all Term Loans
     and/or a reduction in the Term Loan Commitment Amount, and (B) on and after
     the 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 the remaining Term Loan, amortization
     payments, in inverse order in accordance with the amount of each such
     remaining Term Loan amortization payment), until all Term Loans have been

     and the Term Loan Commitment Amount has 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

     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.

                                     -40-

<PAGE>


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 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 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.

     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.

     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.

                                     -42-

<PAGE>


     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 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


                                     -43-

<PAGE>


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 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

                                     -44-

<PAGE>


     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 73
     
          (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 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



                                     -45-

<PAGE>



     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 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


                                     -46-

<PAGE>

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 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


                                     -47-

<PAGE>

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

required to be appended to the Borrower Closing Date Certificate shall be in
form and substance reasonably satisfactory to the Administrative Agent.

     SECTION 5.1.3.  DELIVERY OF NOTES.  The Administrative Agent shall have
received, for the account of each Lender, such Lender's Notes duly executed and

     Agent), pledge to the Administrative Agent all of the outstanding shares of
     capital stock of (i) each U.S. Subsidiary and (ii) any Subsidiary that is

     sentence of this Section, not more than 65% of the capital stock of any
     Foreign Subsidiary shall be so pledged), along with undated stock powers

     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.

which may be the corporate general counsel of the Borrower, (which shall be from
counsel satisfactory to the Administrative Agent) relating thereto, which legal
opinions shall be in form and substance satisfactory to the Administrative
Agent.  The Borrower agrees that if, as a result of a change in law after the
date hereof, (i) a Foreign Subsidiary can execute and deliver a supplement to
the Subsidiary Guaranty or execute and deliver a supplement to the Subsidiary
Pledge Agreement as a pledgor or (ii) the Borrower or any Subsidiary can pledge
more than 65% of the Capital Stock of any Foreign Subsidiary or any intercompany
Indebtedness of any Subsidiary evidenced by a note or other instrument, in any
such case without material adverse tax consequences to the Borrower or such
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

foregoing, the Borrower shall, and shall cause each of its Subsidiaries to,
promptly execute, deliver and/or file (as applicable) Uniform Commercial Code

     Subsidiary or such Obligor, as the case may be, or shall result in the
     entry of an order for relief or shall remain for 60 days undismissed;
     PROVIDED, that the Borrower, each Subsidiary and each Obligor hereby
     expressly authorizes each Secured Party to appear in any court conducting
     any such case or proceeding during such 60-day period to preserve, protect
     and defend their rights under the Loan Documents; or

          (e) take any action authorizing, or in furtherance of, any of the
     foregoing.

     SECTION 8.1.10.  IMPAIRMENT OF SECURITY, ETC.  Any Loan Document or any
Lien granted thereunder shall (except in accordance with its terms), in whole or
in part, terminate, cease to be effective or cease to be the legally valid,
binding and enforceable obligation of any Obligor party thereto; any Obligor or
any other party shall, directly or indirectly, contest in any manner such
effectiveness, validity, binding nature or enforceability; or, except as
permitted under any Loan Document, any Lien securing any Obligation shall, in
whole or in part, cease to be a perfected first priority Lien.

     SECTION 8.1.11.  FAILURE OF SUBORDINATION.  Unless otherwise waived or
consented to by the Administrative Agent, the Lenders and the Issuers in
writing, the subordination provisions relating to any Subordinated Debt (the
"SUBORDINATION PROVISIONS") shall fail to be enforceable by the Administrative
Agent, the Lenders and the Issuers in accordance with the terms thereof, or the
monetary Obligations shall fail to constitute "Senior Indebtedness" (or similar
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


                                     -77-

<PAGE>

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.  

     SECTION 8.1.12. GOVERNMENT CONTRACTS.  Any government contract is
terminated for default or any "show cause" letter is not ultimately cured.

     SECTION 8.2.  ACTION IF BANKRUPTCY.  If any Event of Default described in
CLAUSES (a) through (d) of SECTION 8.1.9 shall occur, the Commitments (if not
theretofore terminated) shall automatically terminate and the outstanding
principal amount of all outstanding Loans and all other Obligations (including
Reimbursement Obligations) shall automatically be and become immediately due and
payable, without presentment, protest, notice or demand (all of which are hereby
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.

     SECTION 8.3.  ACTION IF OTHER EVENT OF DEFAULT.  If any Event of Default
(other than any Event of Default described in CLAUSES (a) through (d) of SECTION
8.1.9) shall occur for any reason, whether voluntary or involuntary, and be
continuing, the Administrative Agent, upon the direction of the Required
Lenders, shall by notice to the Borrower declare all or any portion of the
outstanding principal amount of the Loans and other Obligations (including
Reimbursement Obligations) to be due and payable and/or the Commitments (if not
theretofore terminated) to be terminated, whereupon the full unpaid amount of
such Loans and other Obligations which shall be so declared due and payable
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
Borrower and the Obligors shall automatically and immediately be obligated to
deposit with the Administrative Agent cash collateral in an amount equal to all
Letter of Credit Outstandings.


                                      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
                                     -78-

<PAGE>

thereto.  Each Lender hereby indemnifies (which indemnity shall
survive any termination of this Agreement) the Credit Agents, PRO RATA according
to such Lender's 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 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,

                                     -79-

<PAGE>

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 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.

                                     -80-

     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.

                               MISCELLANEOUS PROVISIONS

     SECTION 10.1.  WAIVERS, AMENDMENTS, ETC.  The provisions of this Agreement
and of each other Loan Document may from time to time be amended, modified or
waived, if such amendment, modification or waiver is in writing and consented to
by the Borrower and the Required Lenders; PROVIDED, HOWEVER, that no such
amendment, modification or waiver shall:

          (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);

                                     -81-

<PAGE>


          (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

     in either case without the consent of all Lenders as expressly provided
     herein or therein;

          (g) change any of the terms of CLAUSE (c) 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.

any party hereto under this Agreement or any other Loan Document shall be in
writing or by facsimile and addressed, delivered or transmitted to such party at

on demand all reasonable expenses of the Administrative Agent (including the
reasonable fees, costs and out-of-pocket expenses of counsel to the


                                     -82-

counsel, if any, who may be retained by counsel to the Administrative Agent) in
connection with

          (a)(i) the syndication efforts of Scotiabank and any due diligence
     investigation; PROVIDED, HOWEVER, that the Borrower shall not pay for
     expenses incurred in connection with assignments which occur after the
     Closing Date and (ii) the negotiation, preparation, execution and delivery
     and administration of this Agreement and of each other Loan Document,
     including schedules and exhibits, and any amendments, waivers, consents,

     Document as may from time to time hereafter be required, whether or not the

all liability for, any stamp or other taxes which may be payable in connection
with the execution or delivery of this Agreement, the Credit Extensions
hereunder, or the issuance of the Notes, Letters of Credit or any other Loan
Documents.  The Borrower also agrees to reimburse each Secured Party upon demand
for all reasonable out-of-pocket expenses (including reasonable attorneys' fees
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"
with the Borrower, whether or not consummated, of any Obligations and (y) the
enforcement of any Obligations.

     SECTION 10.4.  INDEMNIFICATION.  In consideration of the execution and
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

     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

     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);

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.

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

                                     -86-

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.  Notwithstanding any other term 
of this Section, the agreement of 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, 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.

          (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

                                     -87-

     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 

                                     -88-

<PAGE>

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

          (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
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

OPTION, IN THE COURTS OF ANY JURISDICTION WHERE SUCH COLLATERAL OR OTHER
PROPERTY MAY BE FOUND.  THE BORROWER HEREBY

Event of Default has occurred and is continuing, then any such Dividend or
payment shall be paid directly to the Administrative Agent for the benefit of
the Secured Parties.

     SECTION 2.5.  CONTINUING SECURITY INTEREST.  This Pledge Agreement shall
create a continuing security interest in the Collateral and shall

          (a) remain in full force and effect until the Termination Date;

          (b) be binding upon the Pledgor 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 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
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 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.

                            REPRESENTATIONS AND WARRANTIES

     SECTION 3.1.  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 

          (a) any Pledged Interests (other than Pledged Notes) constituting
     Collateral,

               (i) all of such Pledged Interests are duly authorized, and
          validly issued, fully paid, and non-assessable, and constitute that
          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 

                                    -6-
<PAGE>

          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

     SECTION 4.1.  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.

     SECTION 4.1.1.  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

                                    -7-
<PAGE>

     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.

     SECTION 4.1.2.  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.

                                    -8-
<PAGE>

     SECTION 4.1.3.  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.

     SECTION 4.1.4.  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.

     SECTION 4.1.5.  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 

                                    -9-
<PAGE>

          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.

     SECTION 4.1.6.  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, 

                                    -10-
<PAGE>

          (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

     SECTION 5.1.  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.

     SECTION 5.2.  ADMINISTRATIVE AGENT MAY PERFORM.  If the Pledgor fails to
perform any agreement contained herein, the Administrative Agent may perform, or
cause performance of, 

                                    -11-
<PAGE>

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.

     SECTION 5.3.  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.

     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 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

     SECTION 6.1.  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 

                                    -12-
<PAGE>

     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.

     [SECTION 6.2.  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 

                                    -13-
<PAGE>

     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.]

     SECTION 6.3.  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

          (a) any lack of validity 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 any Obligor or any other Person under the provisions of
          the Credit Agreement, any other Loan Document or otherwise, or

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

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

          (e) any amendment to, rescission, waiver, or other modification of, or
     any consent to 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 (including the Collateral), or any amendment to or waiver or
     release of or addition to or consent to departure from any guaranty, for
     any of the Secured Obligations; or


                                       -6-
<PAGE>


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

     SECTION 2.7.  POSTPONEMENT OF SUBROGATION, ETC.  Each Pledgor agrees 
that it will not exercise any rights which it may acquire by reason of any 
payment made hereunder, whether by way of subrogation, reimbursement or 
otherwise, until following the Termination Date.  Any amount paid prior to 
the Termination Date shall be held in trust for the benefit of the Secured 
Parties and shall immediately be paid to the Administrative Agent for the 
benefit of the Secured Parties and credited and applied against the Secured 
Obligations, whether matured or unmatured, in accordance with the terms of 
the Credit Agreement; PROVIDED, HOWEVER, that if

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

          (b) the Termination Date has occurred;

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

                                     ARTICLE III
                            REPRESENTATIONS AND WARRANTIES

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

     SECTION 3.1.1.  OWNERSHIP, NO LIENS, ETC.  Each 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 applicable 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 

          (a) any Pledged Interests (other than Pledged Notes) constituting
     Collateral,

               (i) all of such Pledged Interests are duly authorized, and
          validly issued, fully paid, and non-assessable, and constitute that
          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) in the case of 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

     SECTION 4.1.  COVENANTS.  Each 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.

     SECTION 4.1.1.  PROTECT COLLATERAL; FURTHER ASSURANCES, ETC.  Each 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).  Each 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.  Each Pledgor agrees that from time to
time, at the expense of such 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.  Each Pledgor will pledge hereunder, immediately upon its
acquisition (directly or indirectly) thereof, any and all additional
Indebtedness owed to such Pledgor pursuant to any note with an Obligor.  Each
Pledgor further covenants and agrees as follows:

          (a)  If any 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), such 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 such 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 such 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 any Pledgor, then such 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 such
     Pledgor, as additional collateral securing the Secured Obligations.


                                       -9-
<PAGE>


          (b)  Except as otherwise expressly permitted by the Credit Agreement,
     without the prior written consent of the Administrative Agent, no Pledgor
     will (i) consent to any material modification, extension or alteration of
     the terms of any membership or operating agreement of the LLCs or the
     Partnerships or (ii) accept a surrender of any 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)  Each 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 such 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.

     SECTION 4.1.2.  REGISTRATION OF PLEDGED INTERESTS, ETC.  Concurrently with
the execution and delivery of this Pledge Agreement, each 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 such Pledgor owns a Pledged Interest
(other than in the case of a Certificated Interest or a Pledged Note)) has
registered the pledge by such 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.

     SECTION 4.1.3.  STOCK POWERS, ETC.  Each Pledgor agrees that all
Certificated Interests constituting Collateral delivered by such 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 is necessary under all applicable laws to perfect
the Lien in favor of the Secured Parties on such Collateral.  Each 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.

     SECTION 4.1.4.  CONTINUOUS PLEDGE.  Each 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


                                       -10-
<PAGE>


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 such 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.

     SECTION 4.1.5.  VOTING RIGHTS; DIVIDENDS, ETC.  Each Pledgor agrees:  

          (a) after any Default of the nature referred to in Section 8.1.9 of
     the Credit Agreement or an Event of Default shall have occurred and be
     continuing, promptly upon receipt of notice thereof by such 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 any 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
          each 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
          each 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 any Pledgor but which such Pledgor is then
obligated to deliver to the Administrative Agent, shall, until delivery to the
Administrative Agent, be held by such 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), such
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 such Pledgor, promptly deliver such proxies and other


                                       -11-
<PAGE>


documents, if any, as shall be reasonably requested by such Pledgor which are 
necessary to allow such 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 any Pledgor that would impair any Collateral or be inconsistent with 
or violate any provision of the Credit Agreement or any other Loan Document.

     SECTION 4.1.6.  ADDITIONAL UNDERTAKINGS.  No Pledgor will, 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, each 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)  each 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 any 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.

                               THE Administrative Agent

     SECTION 5.1. ADMINISTRATIVE AGENT APPOINTED ATTORNEY-IN-FACT.  Each 
Pledgor hereby irrevocably appoints the Administrative Agent as such Pledgor's
attorney-in-fact, with full


                                       -12-
<PAGE>


authority in the place and stead of such Pledgor and in the name of such 
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.

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

     SECTION 5.2. ADMINISTRATIVE AGENT MAY PERFORM.  If any Pledgor fails to
perform any agreement contained herein, the Administrative Agent may itself
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 Pledgors pursuant to SECTION 6.4.

     SECTION 5.3. 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 their 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 are 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.

     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;


                                       -13-
<PAGE>


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 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 (or either one 
of them) to comply with any such request at any time shall not in itself be 
deemed a failure to exercise reasonable care.

                                      ARTICLE VI
                                       REMEDIES

     SECTION 6.1.  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.  Each Pledgor agrees that, to the extent notice of sale 
     shall be required by law, at least ten days' prior notice to any 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,


                                       -14-
<PAGE>


               (iv) endorse any checks, drafts, or other writings in any
          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 any Pledgor)
          endorsements, assignments, stock powers and other instruments of
          conveyance or transfer with respect to all or any of the Collateral.

     [SECTION 6.2.  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, each Pledgor agrees that, upon request of either Administrative
Agent, such Pledgor will, at such 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.

Each 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 such Pledgor to perform any of the covenants
contained in this Section and, consequently,


                                       -15-
<PAGE>


jointly and severally, agrees that, if any Pledgor shall fail to perform any 
of such covenants, the Pledgors 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.]

     SECTION 6.3.  COMPLIANCE WITH RESTRICTIONS.  Each 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 are 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 each 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 any Pledgor for any discount
allowed by the reason of the fact that such Collateral is sold in compliance
with any such limitation or restriction.

     SECTION 6.4.  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 applicable Pledgor or to whomsoever may be lawfully entitled to receive such
surplus.

     SECTION 6.5.  INDEMNITY AND EXPENSES.  Each Pledgor hereby jointly and
severally agrees to indemnify and hold harmless the Administrative Agent from
and against any and all claims, losses, and liabilities arising out of or
resulting from this Pledge Agreement (including enforcement of this Pledge
Agreement), except claims, losses, or liabilities resulting from an
Administrative Agent's gross negligence or wilful misconduct.  Upon demand, each
Pledgor jointly and severally agrees that it will pay to the Administrative
Agent the amount of any and all reasonable expenses, including the reasonable
fees and disbursements of their counsel and of any experts and agent, which the
Administrative Agent may incur in connection with:


                                       -16-
<PAGE>


          (a) the administration of this Pledge Agreement, the Credit Agreement
     and any other Loan Document;

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

          (c) the exercise or enforcement of any of the rights of the
     Administrative Agent hereunder; or

          (d) the failure by any Pledgor to perform or observe any of the
     provisions hereof.


                                     ARTICLE VII
                               MISCELLANEOUS PROVISIONS

     SECTION 7.1.  LOAN DOCUMENT.  This Pledge Agreement is a Loan Document
executed pursuant to the Credit Agreement and shall (unless otherwise expressly
indicated herein) be construed, administered and applied in accordance with the
terms and provisions thereof, including Article X thereof. 

     SECTION 7.2.  PROTECTION OF COLLATERAL.  The Administrative Agent may from
time to time, at their option, perform any act which any Pledgor agrees
hereunder to perform and which such Pledgor shall fail to perform after being
requested in writing so to perform (it being understood that no such request
need be given after the occurrence and during the continuance of an Event of
Default) and the Administrative Agent may from time to time take any other
action which the Administrative Agent reasonably deems necessary for the
maintenance, preservation or protection of any of the Collateral or of their
security interest therein.

     SECTION 7.3.  BINDING ON SUCCESSORS, TRANSFEREES AND ASSIGNS; ASSIGNMENT. 
This Pledge Agreement shall be jointly and several binding upon each Pledgor and
its successors, transferees and assigns and shall inure to the benefit of and be
enforceable by each Secured Party and their respective successors, transferees
and assigns; PROVIDED, HOWEVER, that no Pledgor may assign any of its
obligations hereunder without the prior written consent of all Lenders.

     SECTION 7.4.  AMENDMENTS, ETC.  No amendment to or waiver of any provision
of this Pledge Agreement, nor consent to any departure by any Pledgor herefrom,
shall in any event be effective unless the same shall be in writing and signed
by the Administrative Agent (on behalf of the Lenders or the Required Lenders,
as the case may be) and then such waiver or consent shall be effective only in
the specific instance and for the specific purpose for which given.

     SECTION 7.5.  NOTICES.  All notices and other communications provided for
hereunder shall be in writing (including facsimile communication) and, mailed or
telecopied or delivered to each Pledgor, in care of the Borrower at the address

                                       -17-
<PAGE>


notices and other communications, when mailed and properly addressed with 
postage prepaid or if properly addressed and sent by pre-paid courier 
service, shall be deemed given when received; any such notice or 
communication, if transmitted by telecopier, shall be deemed given when 
transmitted and electronically confirmed.

     SECTION 7.6.  ADDITIONAL SUBSIDIARY PLEDGORS.  Upon the execution and

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

     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.

     SECTION 4.1.3.  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 (i) 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, (ii) 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 (iii) 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.

     Patent Collateral is of negligible economic value to the Grantor, or (ii)

     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

          services offered under all of the Trademark Collateral,

               (iii) fail to employ all of the Trademark Collateral registered
          with any Federal or state or foreign authority with an appropriate
          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 


                                     -13-
<PAGE>

          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 taxes (except to the
     extent that dedication, abandonment or invalidation is permitted under the
     foregoing CLAUSES (a), (b) and (c)).

          (g) The Grantor shall, contemporaneously herewith, execute and deliver
     to the Administrative Agent a Patent Security Agreement, a Trademark
     Security Agreement and a Copyright Security Agreement in the forms of
     EXHIBIT A, EXHIBIT B and 


                                     -14-
<PAGE>

     EXHIBIT C hereto, respectively, and shall execute and deliver to the 
     Administrative Agent any other document required to acknowledge or 
     register or perfect the Administrative Agent's interest in any part of 
     the Intellectual Property Collateral.

     SECTION 4.1.5.  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.

     SECTION 4.1.6.  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.

     SECTION 4.1.7.  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


                                     -15-
<PAGE>

          (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. Section 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


                                        -16-
<PAGE>

     SECTION 5.1. 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.

     SECTION 5.2.  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.

     SECTION 5.3.  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; 


                                     -17-
<PAGE>

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

     SECTION 6.1.  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.

          (b) 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 


                                     -18-
<PAGE>

     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.

     SECTION 6.2.  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 payment of (i) all Obligations of the Borrower now or hereafter existing
under the Credit Agreement and each other Loan Document to which the Borrower is
or may become a party, whether for principal, interest, costs, fees, expenses or
otherwise, and (ii) all obligations of each Grantor and each other Obligor now
or hereafter existing under this Security Agreement and each other Loan Document
to which such Grantor or such other Obligor is or may become a party, with all
such obligations of the Borrower and such Grantor and such other Obligor being
collectively referred to as the "SECURED OBLIGATIONS".

     SECTION 2.3.  CONTINUING SECURITY INTEREST; TRANSFER OF NOTES.  This
Security Agreement shall create a continuing security interest in the Collateral
and shall

          (a) remain in full force and effect until the Termination Date;

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

          (c) inure, together with the rights and remedies of the Administrative

     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 each Grantor's sole expense, execute and deliver to the
applicable Grantor (without any representations, warranties or recourse to
either Administrative Agent), such documents as such Grantor shall reasonably
request to evidence such termination.

     SECTION 2.4.  GRANTOR REMAINS LIABLE.  Anything herein to the contrary
notwithstanding

          (a) each 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;

                                     -7-

<PAGE>


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

          (c) neither 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 any Grantor thereunder or to take any
     action to collect or enforce any claim for payment assigned hereunder.

     SECTION 2.5.  SECURITY INTEREST ABSOLUTE.  All rights of the Administrative
Agent and the security interests granted to the Administrative Agent hereunder,
and all obligations of each Grantor hereunder, shall be absolute and
unconditional, irrespective of

     (a)  any lack of validity 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 any Obligor or any other Person 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
     of, or collateral securing, any Secured Obligations;

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

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

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

                                     -8-

<PAGE>


     (f)  any addition, exchange, release, surrender or non-perfection of any
collateral (including the Collateral), or any amendment to or waiver or release
of or addition to or consent to departure from any guaranty, for any of the
Secured Obligations; or

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

     SECTION 2.6.  POSTPONEMENT OF SUBROGATION, ETC.  Each Grantor agrees that
it will not exercise any rights which it may acquire by way of rights of
subrogation under this Security Agreement, by any payment made hereunder,
whether by way of subrogation, reimbursement or otherwise, until following the
Termination Date.  Any amount paid to any Grantor 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 to the
Administrative Agent for the benefit of the Secured Parties and credited and
applied against the Obligations, whether matured or unmatured, in accordance
with the terms of the Credit Agreement; PROVIDED, HOWEVER, that if 

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

          (b) the Termination Date has occurred;

then each Secured Party agrees that, at such Grantor's request, the
Administrative Agent, on behalf of the Secured Parties, will execute and deliver
to such Grantor appropriate documents (without recourse and without
representation or warranty) necessary to evidence the transfer by subrogation to
such Grantor of an interest in the Obligations resulting from such payment by
such Grantor.  In furtherance of the foregoing, at all times prior to the
Termination Date, each Grantor shall refrain from taking any action or
commencing any proceeding against any 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
Security Agreement to any Secured Party.  Notwithstanding the foregoing, to the
extent necessary to toll the statute of limitations, such Grantor 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.

     in the Collateral Account to the payment of any Secured Obligations which

     hereunder pursuant to CLAUSE (C) of SECTION 2.1 (including Liens granted by
     other Grantors), or pursuant to the Borrower Security Agreement to exceed
     $2,000,000 at any time.

     SECTION 4.1.3.  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 such Grantor of the
     revocation of such power and authority such Grantor (i) 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 such 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 such Grantor for
     such purpose,(ii) 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 such Grantor may
     deem advisable, and (iii) 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

          (b) The Administrative Agent is authorized to endorse, in the name of
     such Grantor, any item, howsoever received by the Administrative Agent,

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

          (a)Such Grantor shall not, unless such 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 such 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)Such Grantor shall not, and such Grantor shall not permit any of
     its licensees to, unless such 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 such 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,

               (iii) fail to employ all of the Trademark Collateral registered
          with any Federal or state or foreign authority with an appropriate
          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.

                                     -15-

<PAGE>


          (c)Such Grantor shall not, unless such 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 such 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) Such 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 such 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 such 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 such Grantor relating thereto or represented
     thereby.

          (f)Such 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 

                                     -16-

<PAGE>


     payment of fees and taxes (except to the extent that dedication, 
     abandonment or invalidation is permitted under the foregoing CLAUSES 
     (A), (B) and (C)).

          (g)Such Grantor shall, contemporaneously herewith, execute and deliver
     to the Administrative Agent a Patent Security Agreement, a Trademark
     Security Agreement and a Copyright Security Agreement in the forms of
     EXHIBIT A, EXHIBIT B and EXHIBIT C hereto, respectively, and shall execute

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

maintained with responsible insurance companies insurance with respect to its
business and properties (including the Equipment and Inventory) against such

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 such Grantor
in accordance with this Section.  Without limiting the foregoing, such 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) Such Grantor shall, if so requested by the Administrative Agent,
     deliver to the Administrative Agent a copy of each insurance policy.

     SECTION 4.1.6.  TRANSFERS AND OTHER LIENS.  Such Grantor shall not:

     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

     SECTION 4.1.7.  FURTHER ASSURANCES, ETC.  Such 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, such 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, and 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. Section 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,
such 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 such 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.

                                      THE AGENT

     SECTION 5.1. ADMINISTRATIVE AGENT APPOINTED ATTORNEY-IN-FACT.  Each 
Grantor hereby irrevocably appoints the Administrative Agent such Grantor's 
attorney-in-fact, with full authority in the place and stead of such Grantor 
and in the name o tf such 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 such Grantor hereunder
     (including all obligations of such Grantor pursuant to SECTION 4.1.7).

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

     SECTION 5.2.  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 such
Grantor pursuant to SECTION 6.2.

     SECTION 5.3.  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.

                                     -19-

<PAGE>


     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

     SECTION 6.1.  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 each Grantor to, and such 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.  Each Grantor agrees that, to the extent notice of sale
          shall be required by law, at least ten days' prior notice to such
          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.

          (b) 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


                                     -20-

<PAGE>

     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.

     SECTION 6.2.  INDEMNITY AND EXPENSES.

          (a) Each Grantor jointly and severally 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) Each 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.

     Re:  THE TITAN CORPORATION

Ladies and Gentlemen:

This letter is furnished to you in connection with the Credit Agreement, dated
as of July 29, 1998 (the "CREDIT AGREEMENT"), between The Titan Corporation (the
"BORROWER"), various financial institutions from time to time parties thereto
(the "LENDERS"), The Bank of Nova Scotia as the agent for the Lenders (in such
capacity, the "AGENT"), and Imperial Bank as the documentation agent.  Unless
otherwise defined, terms used herein have the meanings provided in the Credit
Agreement.

In connection with this opinion, I have examined originals or copies, certified
or otherwise identified to my satisfaction, of such certificates or comparable
documents of public officials and of officers and other representatives of the
Borrower and the Subsidiaries, and such other agreements, instruments and other
documents, as I have deemed necessary for the purposes of this opinion.

In addition, in connection with this opinion, I have examined originals or
copies, certified or otherwise identified to my satisfaction, of the following
documents (each dated July 29, 1998, unless otherwise stated):

     (a)  the Credit Agreement;

     (b)  the Notes;


<PAGE>



     (c)  the Borrower Security Agreement;

     (d)  the Subsidiary Security Agreement; 

     (e)  the Borrower Pledge Agreement;

     (f)  the Subsidiary Pledge Agreement;

     (g)  the Subsidiary Guaranty;

     (h)  the Intercompany Subordination Agreement;

     (i)  the Trademark Security Agreement;

     (j)  the Patent Security Agreement;

     (k)  the Copyright Security Agreement;

     (l)  copies of the Articles and Certificates of Incorporation and By-Laws
          described on Exhibit "A" attached hereto (collectively, the "Organic
          Documents");

     (m)  copies of the resolutions of the Board of Directors of the entities
          described on Exhibit "A" attached hereto; and

     (n)  copies of the good standing/status certificates described on Exhibit
          "B" attached hereto.

For purposes of this opinion, the agreements, documents, notes and instruments
referred to in clauses (a) through (k) above are hereinafter collectively
referred to as the "TRANSACTION DOCUMENTS."  The Persons described on Exhibit
"A" other than Borrower are sometimes collectively referred to herein as the
"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 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 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 Agent pursuant to the
               terms of a Transaction Document.

     4.   Each 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 Subsidiary;

          (b)  contravene any law or governmental regulation or, to the best of
               my knowledge, any contractual restriction, court decree or order
               binding on 

<PAGE>



The Bank of Nova Scotia

Page 4


               or affecting such Subsidiary, 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
               Subsidiary, other than a Lien in favor of the 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 of any of the
     Transaction Documents to which it is a party.

     6.   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 each Subsidiary of any of the
     Transaction Documents to which it is a party.

     7.   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.

     8.   There is no pending, nor, to the best of my knowledge after due
     inquiry, threatened litigation, action, proceeding, investigation or labor
     controversy affecting each 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.

     9.   The Pledged Interests (as defined in the Borrower Pledge Agreement),
     other than Pledged Notes (as defined in the Borrower Pledge Agreement),
     issued by the Subsidiaries listed in ATTACHMENT I to the Borrower Pledge
     Agreement 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 Subsidiaries.


<PAGE>


The Bank of Nova Scotia

     10.  The Pledged Interests (as defined in the Subsidiary Pledge Agreement),
     other than Pledged Notes (as defined in the Subsidiary Pledge Agreement),
     issued by the Subsidiaries listed in ATTACHMENT I to the Subsidiary Pledge
     Agreement 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 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 and the 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 and the
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 and the
Subsidiaries) and constitutes or will constitute the legal, valid and binding
obligation of each Person (other than the Borrower and the Subsidiaries),
enforceable in accordance with its terms; and that each Person (other than the
Borrower and the 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 and the Subsidiaries, no information that would give me current actual
knowledge of the inaccuracy of such statement has come to my attention.

I express no opinion herein as to any law other than the laws of the State of
California, the general corporate laws of the State of Delaware, and the federal
law of the United States.  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.

The opinions expressed herein have been rendered at your request, are solely for
your benefit in connection with the transactions contemplated by the Transaction
Documents and may not be relied upon by you in any other manner or by any other
Person in any manner or for any purpose and may not be communicated or published

Re:   THE TITAN CORPORATION

Ladies and Gentlemen:

This letter is furnished to you in connection with the Credit Agreement, dated

(the "LENDERS"), The Bank of Nova Scotia as the agent for the Lenders (in such

We have acted as special counsel to the Borrower and its Subsidiaries in

below). In that regard, we have examined originals or copies, certified or 
otherwise identified to our satisfaction, of the following documents (each 
dated July 29, 1998, unless otherwise stated):

      a.     the Credit Agreement;

      b.     the Notes;

             California UCC, naming the Borrower as debtor and the
             Administrative Agent as secured party, covering the Collateral
             described in the Borrower Security Agreement and the Borrower
             Pledge Agreement (the "BORROWER SECURITY AGREEMENT COLLATERAL"),
             which Financing Statements will be filed in the filing offices (the
             "BORROWER SECURITY AGREEMENT FILING OFFICES") listed in ITEM A in
             SCHEDULE I hereto; and

      m.     execution copies of financing statements on Form UCC-1 (the
             "SECURITY AGREEMENT FINANCING STATEMENTS") under the California
             UCC, naming the relevant Subsidiary as debtor and the

             "SECURITY AGREEMENT FILING OFFICES") listed in ITEM B in SCHEDULE I
             hereto.
      
For purposes of this opinion, the agreements, documents, notes and instruments

"A" other than Borrower are sometimes collectively referred to herein as the

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 Transaction 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

internal laws of the States of New York, 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 Transaction
Documents with respect to contracts with any governmental agency involving
matters of national security or other sensitive military or governmental
activities.

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 Transaction
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 UCC-1s
filed in the appropriate California governmental office will at all relevant
times be located in the State of California; (iii) at all relevant times, each
of the parties (other than the Borrower and the Subsidiaries) to the Transaction
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 Transaction 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; and (iv) the execution, delivery and performance at closing of the 
Transaction Documents by each party, other than the Borrower and the 
Subsidiaries, 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.

      (3)    We have assumed that:  (i) other than the Transaction 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, supplement or qualify the terms of any of the
Transaction Documents, and (ii) each of the Borrower and the Subsidiaries has
rights in the Collateral owned by it such that each item of Collateral
constitutes property in which a security interest can be granted under the UCC,
and that each of the Borrower and the 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: 

      1.     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.

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

      3.     The Borrower Pledge Agreement creates a valid security interest in
favor of the Administrative Agent in the Collateral (as defined in the Borrower
Pledge Agreement), as security for the Secured Obligations (as defined in the
Borrower Pledge Agreement), 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 (either in California
or New York) results in the perfection of such security interest, and, further,
the Administrative Agent is a "protected purchaser" of such Pledged Interests.

      4.     The Subsidiary Pledge Agreement creates a valid security interest
in favor of the Administrative Agent in the Collateral (as defined in the
Subsidiary Pledge Agreement), as security for the Secured Obligations (as
defined in the Subsidiary Pledge Agreement), 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 (either in California or New York) results in the
perfection of such security interest, and, further, the Administrative Agent is
a "protected purchaser" of such Pledged Interests.

      5.     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 Security Agreement 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 Borrower continues to be
located in California within the meaning of Section 9-103 of the UCC). 

      6.     The provisions of the Subsidiary 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 



<PAGE>

The Bank of Nova Scotia
July 29, 1998
Page 6


security interest in all right, title and interest of each Subsidiary in and 
to all Subsidiary Security Agreement 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). 

      7.     The Financing Statements are in appropriate form for filing and,
upon the filing of (a) the Borrower Security Agreement Financing Statements in
the Borrower Security Agreement Filing Offices, and (b) the Security Agreement
Financing Statements in the Security Agreement Filing Offices, and the payment
of the fees and charges set forth on SCHEDULE I hereto which are required in
connection with such filings, the Administrative Agent's security interest in
all right, title and interest of the Obligors in and to the Borrower UCC
Collateral and the Subsidiary UCC Collateral, 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 offices.

      8.     Except for the filing of (a) the Borrower Security Agreement
Financing Statements in the Borrower Security Agreement Filing Offices, and (b)
the Security Agreement Financing Statements in the Security Agreement Filing
Offices, and the payment of the fees and charges described in PARAGRAPH 7 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, other than the filings and actions described above (regarding
Pledged Interests) or below.

      9.     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, except for
(i) recording the Trademark Security Agreement and the Patent Security Agreement
with the United States Patent and Trademark Office and 



<PAGE>

The Bank of Nova Scotia
July 29, 1998
Page 7


the Copyright Security Agreement with the United States Copyright Office, and 
(ii) filing the Financing Statements in the appropriate filing offices in all 
appropriate jurisdictions.

      10.    The Copyright Security Agreement creates 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 Office (each a "Copyright" and collectively the "Copyrights").  Upon
the proper filing of the Financing Statements in the offices listed in Schedule
I hereto and the recordation of the Copyright Security Agreement in the United
States Copyright Office, the Administrative Agent will have a perfected security
interest in each Copyright.

      11.    The Patent Security Agreement creates 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 Financing Statements in the offices listed in Schedule I
hereto and the recordation of the Patent Security Agreement in the United States
Patent and Trademark Office, the Administrative Agent will have a perfected
security interest in each Patent.

      12.    The Trademark Security Agreement creates a 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 Financing Statements in the
offices listed in Schedule I hereto and the recordation of the Trademark
Security Agreement in the United States Patent and Trademark Office, the
Administrative Agent will have a perfected security interest in each Trademark.

                       ADDITIONAL ASSUMPTIONS, QUALIFICATIONS, 
                              LIMITATIONS AND EXCEPTIONS

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

      (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
Transaction Documents, and we are not expressing any opinion as to the effect of
compliance by any party to the Transaction Documents with


<PAGE>

The Bank of Nova Scotia
July 29, 1998
Page 8


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 and the 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 or the Subsidiaries to 
perform their respective obligations under the Transaction Documents.  
However, to our best knowledge, Borrower and the Subsidiaries are not subject 
to any licensing or other regulatory requirements or provisions under New 
York, California or Federal law. 

      (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 Borrower and the 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 Borrower and the Subsidiaries in
connection with this transaction.

      (iii)  For purposes of our opinions 3 and 4 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 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 proceeds or other
distributions received in connection therewith.  For the purposes of opinions 9
through 12 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 Agreement, the Patent Security Agreement and the Trademark Security
Agreement, respectively, is as indicated on the Schedules attached thereto.

      (iv)   Our opinions set forth in paragraphs 1 and 2 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
      Transaction 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 Transaction 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 (i) 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 above), (ii) any equipment, rail
cars or vehicles as to which perfection of a security interest is 


<PAGE>

The Bank of Nova Scotia
July 29, 1998
Page 10


dependent upon a notation being made on a certificate of title or the like, 
(iii) 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.), (iv) 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 Lender 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 Transaction 
Documents together with the filing of the Financing Statements and the 
Administrative Agent's taking possession of the Pledged Interests as noted 
above, (v) balances, credits, deposits, accounts, deposit accounts or monies 
maintained at an office or branch of the Lender other than an office or 
branch located within the State of California, (vi) goods which are moveable 
in nature, (vii) 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 Transaction Documents, (viii) goods as 
against a consignor which has delivered or may hereafter deliver such goods 
to the Borrower or the Subsidiaries under a true consignment (as 
distinguished from a consignment intended as security), (ix) 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, (x) inventory in the event of any failure 
by the Borrower or the 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 (xi) 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 Transaction Documents (other than the specific opinion rendered above in 
paragraphs 3 and 4 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 Transaction
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>

The Bank of Nova Scotia

      (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 (i) 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 (ii) 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 (i)
relocated to another jurisdiction, refiling in such jurisdiction may be required
to continue perfection under the laws of such jurisdiction, and (ii) 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 the locations in California described in Schedule I attached hereto 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 (i) 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, (ii) 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, (iii) 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 (iv) 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.

The Bank of Nova Scotia

Page 12


      (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.

      (xiii) We express no opinion with respect to the validity, binding effect
or enforceability of any provision of the Transaction Documents which purports
to authorize the Lender 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 (i) the title to or the descriptions
of, any security interest in any property described in the Transaction Documents
in which a security interest has been granted pursuant to the Transaction
Documents; (ii) 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); (iii)
whether such property is the property intended to secure the obligations of the
Borrower under the Transaction Documents; and (iv) 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.

The Bank of Nova Scotia

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

             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 Transaction 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 Transaction 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
      Transaction 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 Transaction Documents;

             d)   To the extent public policy limits provisions of the
      Transaction Documents that purport to indemnify or otherwise exonerate any
      party to the Transaction 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 Borrower or the Subsidiaries to
      object to subject matter, jurisdiction or venue, or to assert any defense
      based on lack of subject matter, jurisdiction or venue;



<PAGE>

The Bank of Nova Scotia
July 29, 1998
Page 14


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

             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 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
Transaction 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 (i) 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, (ii) any provision of any Transaction 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, (iii) any provisions which purport to create a power of attorney,
proxy or agency relationship, (iv) any provision in the Transaction Documents
that provides for a power of attorney or for the appointment of a receiver as a
matter of right, (v) except as expressly addressed by the opinions set forth
above, any schedule or exhibit to any of the Transaction Documents, (vi) the
enforceability of any indemnity or reimbursement obligation by the Borrower or
the 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 (vii) any provision of the Transaction Documents
that purports to allow a set off by the Administrative Agent or the Lenders
against funds held by the Borrower or the Subsidiaries in trust, special
accounts or other segregated accounts.

                                 SUBSIDIARY GUARANTY

     This SUBSIDIARY GUARANTY (as amended, supplemented, amended and restated or

                                 W I T N E S S E T H:

     WHEREAS, pursuant to a Credit Agreement, dated as of July 29, 1998 (as

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:

                                 GUARANTY PROVISIONS

     SECTION 2.1.  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

                                         2
<PAGE>

     automatic stay under Section 362(a) of the United States Bankruptcy Code,
     11 U.S.C. Section 362(a), and the operation of Sections 502(b) and 506(b)
     of the United States Bankruptcy Code, 11 U.S.C. Section 502(b) and Section
     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.

     SECTION 2.2.  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.


     SECTION 2.3.  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


                                         -3-
<PAGE>

               (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.

     SECTION 2.4.   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


                                         -4-
<PAGE>

addition to other rights and remedies (including other rights of setoff under
applicable law or otherwise) which such Secured Party may have.

     SECTION 2.5.  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.

     SECTION 2.6.  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.

     SECTION 2.7.  SUCCESSORS, TRANSFEREES AND ASSIGNS, ETC.  This Guaranty
shall:


                                         -5-
<PAGE>

          (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.

     SECTION 2.8.  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


                                         -6-
<PAGE>

(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

     SECTION 3.1.  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

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

          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


                                         -4-
<PAGE>


               (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


                                         -5-
<PAGE>

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 July
     [ ], 1998) 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 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


                                         -6-
<PAGE>

          (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 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 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


                                         -7-
<PAGE>

          (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 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 herefrom, 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


                                         -8-
<PAGE>

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)

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.

Senior Indebtedness shall have been paid in cash in full and all Commitments

Credit Agreement, assign or otherwise transfer the Senior Indebtedness held by

such other Person shall thereupon become vested with all the rights in respect

                               THE TITAN CORPORATION

Gentlemen and Ladies:

     We refer to clause (d) of Section 10.11.1 of the 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 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 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 ______ __, 19__ (the "ASSIGNMENT DATE"), ______________ (the
"ASSIGNOR") irrevocably sells, transfers, conveys and assigns, without recourse,
representation or warranty (except as expressly set forth herein), to
______________ (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") with conveyances of the Revolving
Loans to include the Assignor's pro rata portion of any Letter of Credit
Outstandings the Assignor outstanding under the Credit Agreement, 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.

<PAGE>

     The Assignee shall pay to the Assignor on the Assignment Date an amount

accrued and unpaid commitment fees payable under Section 3.3.1 of the Credit
Agreement and Letter of Credit fees payable under Section 3.3.3 of the Credit
Agreement with respect to the Assigned Portion.  In addition, the Assignor shall

Letter of Credit fees, if any, which have been paid in advance pursuant to
Section 3.3.3 of the Credit Agreement for the period from and after the
Assignment Date.  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 Assignee
further confirms and agrees that in becoming a Lender and in making its
Commitments and Credit Extensions under the Credit Agreement, such actions have
and will be made without recourse to, or representation or warranty by, the
Administrative Agent.

     The Assignor represents and warrants that it is legally authorized to enter
into and deliver this agreement and represents that it is the legal and
beneficial owner of the Assigned Portion.  Except as set forth in the previous
sentence, the Assignor makes no representation or warranty and assumes no
responsibility with respect to any statements, warranties or representations
made pursuant to or in connection with this agreement, or the execution,
legality, validity, enforceability, genuineness, sufficiency or value of this
agreement, the Credit Agreement, any other Loan Document or any other instrument
or document furnished pursuant hereto or thereto, including the financial
condition of the Borrower or any of their Subsidiaries or the performance or
observance by any Lender of any of its obligations under the Credit Agreement,
any other Loan Document or any other instrument or document furnished pursuant
hereto or thereto.  The Assignee represents and warrants that it is legally
authorized to enter into and deliver this agreement and confirms that it has
received a copy of the Credit Agreement, together with copies of the most recent
financial statements delivered pursuant to Section 7.1.1 of the Credit Agreement
and such other documents and information as it has deemed appropriate to make
its own credit analysis and decision to enter into this agreement.  In addition,
the Assignee independently and without reliance upon the Assignor, the Agents or
any other Lender, and based on such documents and information as it shall deem
appropriate at the time, shall continue to make its own credit decisions in
taking or not taking action under the Credit Agreement, the other Loan Documents
and the other instruments and documents delivered in connection therewith.

     Except as otherwise provided in the Credit Agreement, effective as of the
Assignment Date

          (a)  the Assignee


                                         -2-

          Credit Agreement and shall have all the rights and obligations of a
          "Lender" under the Credit Agreement and the other Loan Documents as if
          it were an original signatory thereto to the extent specified in the
          second paragraph hereof;

               (ii)  agrees to be bound by the terms and conditions set forth in
          the Credit Agreement and the other Loan Documents as if it were an
          original signatory thereto; and

          (b)  the Assignor shall be released from its obligations under the
     Credit Agreement and the other Loan Documents to the extent specified in
     the second paragraph hereof.

     The Assignee hereby advises each of you that the Assignee's administrative
details with respect to the assigned Credit Extensions and Commitments are on
file with the Administrative Agent and requests the Administrative Agent to
acknowledge receipt of this document.

     The Assignee agrees (for the benefit of the Assignor, the Borrower and the
Administrative Agent) to furnish, if required by clause (e) of Section 4.6 of
the Credit Agreement, the applicable Internal Revenue Service forms or other
forms required thereunder no later than the date of acceptance hereof by the
Agents.  In addition, the Assignee represents and warrants (for the benefit of
the Assignor, the Borrower and the Administrative Agent) that, under applicable
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
shall not be effective unless such consents shall have been obtained and in any
event no such assignment and delegation shall be effective unless and until such
assignment has been recorded in the Register by the Administrative Agent.

     This Agreement may be executed by the Assignor and Assignee in separate
counterparts, each of which when so executed and delivered shall be deemed to be
an original and all of which taken together shall constitute one and the same
agreement.

                                 SOLVENCY CERTIFICATE


     This Certificate (this "CERTIFICATE") is delivered in connection with the
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 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 Credit Agreement.

     The undersigned hereby certifies that 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:

          (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 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

<PAGE>

               (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 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 present "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 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 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 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
     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

<PAGE>

     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
     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.


                                         -3-

     IN WITNESS WHEREOF, the undersigned Authorized Officer has executed this
Certificate on this 29th day of July, 1998.
