         NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1.  FINANCIAL STATEMENTS
    SUMMARY OF OPERATIONS AND BASIS OF PRESENTATION

     Omega Protein Corporation ("Omega" or the "Company"), produces and markets
a variety of products produced from menhaden (a fish found in commercial
quantities), including regular grade and value added specialty fish meals, crude
and refined fish oils and fish solubles. The Company's fish meal products are
used as nutritional feed additives by animal feed manufacturers and by
commercial livestock and poultry farmers. The Company's crude fish oil is sold
to food producers in Europe, and its refined fish oil products are used in
aquaculture feeds and certain industrial applications. Fish solubles are sold as
protein additives for animal feed and as organic fertilizers.

     On January 26, 1998, Marine Genetics Corporation ("Marine Genetics") merged
into Omega, a Nevada corporation wholly-owned by Zapata Corporation ("Zapata"),
with Omega Protein Corporation being the surviving entity.  The common control
merger was accounted for at historical cost in a manner similar to that in a
pooling of interests accounting. In connection with the merger, Marine Genetics
outstanding common stock was converted into Omega common stock at the rate of
one share for 19,676 shares of Omega common stock and Omega's pre-merger
outstanding common stock was canceled and treated as treasury stock.  As a
result, the Company's capitalization at September 30, 1997, is as follows:
authorized capital stock of 80,000,000 shares common stock, par value $0.01 per
share; 10,000,000 shares of preferred stock, par value of $0.01 per share; and
19,676,000 shares of issued and outstanding common stock.

     On April 8, 1998, the Company completed an initial public offering of
8,500,000 of its common stock at a gross price of $16.00 per share. On May 7,
1998, the Underwriters exercised their option to acquire 1,275,000 additional
shares at the same gross price. Of the 9,775,000 total shares sold in the
offering, the Company issued and sold 4,600,000 shares, and Zapata sold
5,175,000 shares. Zapata now owns approximately 59.7% of the shares of the
Company's outstanding common stock.  As a result of the Company's completed
public offering, the Company's capitalization at June 30, 1998 is as follows:
authorized capital stock of 80,000,000 shares common stock, par value $0.01 per
share; 10,000,000 shares of preferred stock, par value $0.01 per share; and
24,276,000 shares of issued and outstanding common stock.
 
     The unaudited condensed consolidated financial statements included herein
have been prepared by Omega, without audit, pursuant to the rules and

nature.  The condensed consolidated balance sheet at September 30, 1997 has been
derived from the audited financial statements at that date. Although Omega
believes that the disclosures are adequate to make the information presented not
misleading, certain information and footnote disclosures, including a
description of significant accounting policies, normally included in financial

condensed consolidated financial statements should be read in conjunction with
the financial statements and the notes thereto included in Omega's Registration
Statement on Form S-1 (Reg. No.333-44967) filed with the Securities and Exchange
Commission on January 27, 1998, as amended through and declared effective on
April 2, 1998. The results of operations for the three months and nine months
ended June 30, 1998 are not necessarily indicative of the results to be expected
for any subsequent quarter or the entire fiscal year ending September 30, 1998.

New Accounting Pronouncements

     In February 1997, the FASB issued Statement of Financial Accounting
Standards No. 128, "Earnings Per Share" ("SFAS 128"), which established
standards for computing and presenting earnings per share. The Company adopted
the statement on October 1, 1997. Basic earnings per share was computed by
dividing income by the weighted average number of common shares outstanding.
Diluted earnings per share was computed by dividing income by the sum of the
weighted average number of common shares outstanding and the effect of any
dilutive stock options.

     In June 1997, the FASB issued Statement of Financial Accounting Standards
No. 130, "Reporting Comprehensive Income" ("SFAS 130"), which is effective for
fiscal years beginning after December 15, 1997. SFAS 130 establishes standards
for reporting and display of comprehensive income and its components (revenues,
expenses, gains and losses) in a full set of general-purpose financial
statements. It requires (a) classification of items of other comprehensive
income by their nature in a financial statement, and (b) display of the
accumulated balance of other comprehensive income separate from retained
earnings and additional paid-in capital in the equity section of a statement of
financial position. The Company will adopt the provisions of the statement in
fiscal 1999. The Company anticipates that implementing the provisions of SFAS
130 will not have a significant impact on the Company's existing operations.

     In June 1997, the FASB also issued Statement of Financial Accounting
Standards No. 131, "Disclosure About Segments of an Enterprise and Related
Information" ("SFAS 131"), which is effective for periods beginning after
December 15, 1997.  The statement need not be applied to interim financial
statements in the initial year of its application.  SFAS 131 establishes
standards for reporting information about operating segments in annual financial
statements and requires selected information about operating segments in interim
financial reports issued to shareholders.  It also establishes standards for
related disclosures about products and services, geographic areas and major
customers.  This Statement supersedes SFAS 14, "Financial Reporting for Segments
of a Business Enterprise," but retains the requirement to report information
about major customers.  The Company will adopt the provisions of the statement
in fiscal 1999. The Company anticipates that implementing the provisions of SFAS
131 will not have a significant impact on the Company's existing operations.

     In February 1998, the FASB issued Statement of Financial Accounting
Standards No. 132, "Employers' Disclosures About Pensions and Other
Postretirement Benefits" ("SFAS 132"), which is effective for fiscal years
beginning after December 15, 1997. SFAS 132 significantly changes 

                                       7
<PAGE>
 
current financial statement disclosure requirements from those that were
required under SFAS 87, "Employers' Accounting for Pensions"; SFAS 88,
"Employers' Accounting for Settlements and Curtailments of Defined Benefit
Pension Plans and for Termination Benefits"; and SFAS 106, "Employers'
Accounting for Postretirement Benefits Other Than Pensions." SFAS 132 does not
change the existing measurement or recognition provisions of FASB Statement Nos.
87, 88 or 106. It requires that additional information be disclosed regarding
changes in benefit obligation and fair values of plan assets, standardizes the
disclosure requirements for pensions and other postretirement benefits and
presents them in one footnote, and eliminates certain disclosures that are no
longer considered useful. The Company will adopt the provisions of the statement
in fiscal 1999.

     In June 1998, the FASB issued Statement of Financial Accounting Standards
No. 133, "Accounting for Derivative Instruments and Hedging Activities" (SFAS
133), which is effective for fiscal years beginning after June 15, 1999. SFAS
133 establishes standards requiring all derivatives to be recognized in the
statement of financial position as either assets or liabilities and measured at
fair value. The Company will adopt the provisions of the statement in fiscal
year 2000. The Company anticipates that implementing the provisions of SFAS 133
will not have a significant impact on the Company's existing operations.

2.  ASSET ACQUISITIONS

      On November 3, 1997, the Company acquired the fishing and processing
assets of American Protein, Inc. ("American Protein"), which operated ten
steamers and a menhaden processing plant in the Chesapeake Bay area, for $14.5
million in cash (the "American Protein Acquisition"). American Protein's
facilities were located in close proximity to the Company's Reedville, Virginia
facility.  Shortly after completing this transaction, the Company closed the
American Protein processing plant and began integrating its assets into the
Company's existing operations.

     On November 25, 1997, the Company purchased the fishing and processing
assets of Gulf Protein, Inc. ("Gulf Protein"), which included six steamers, five
spotter planes and the processing equipment located at the Gulf Protein plant
near Morgan City, Louisiana for $13.6 million in cash and the assumption of
$883,000 in liabilities (the "Gulf Protein Acquisition").  The Company accounted
for this acquisition as a purchase; thus, the results of operations began being
included in the Company's Statement of Operations beginning November 25, 1997.
In connection with the Gulf Protein Acquisition, the Company also entered into a
five-year lease for the Gulf Protein plant at a $220,000 annual rental rate.
The Company is currently upgrading this plant's processing capabilities so that
it can manufacture specialty meals. The Company began operations at the Morgan
City, Louisiana plant at the start of the 1998 fishing season.

     These acquisitions were financed by a $28.1 million intercompany loan from
Zapata. The interest rate on this loan was 8.5 % and was repayable in quarterly
installments beginning May 1, 1998. The loan, which was to mature on August 1,
2002, was prepaid in May 1998 with a portion of the proceeds from the Company's
initial public offering described in Note 1.

3.  INVENTORIES

     Fish product inventories are stated at the lower of cost or market.
Materials, parts and supplies are stated at average cost.
 
     The Company's fishing season runs from mid-April to the end of October in
the Gulf Coast and from the beginning of May to the end of December in the
Atlantic Coast. Government regulations preclude the Company from fishing during
the off-seasons. During the off-seasons, the Company incurs costs (i.e., plant
and vessel related labor, utilities, rent and depreciation) that are directly
related to the Company's infrastructure that will be used in the upcoming
fishing season. Costs that are incurred subsequent to a fish catch are deferred
until the next season and are included with inventory.
 
     The Company's inventory cost system considers all costs, both variable and
fixed, associated with an annual fish catch and its processing. The Company's
costing system allocates cost to inventory quantities on a per unit basis as
calculated by a formula that considers total estimated inventoriable costs for a
fishing season (including off-season costs) to total estimated fish catch. The
inventory is relieved at average cost as the product is sold. The Company
adjusts the cost of sales, off-season costs and inventory balances at the end of
each quarter based on revised estimates of total inventoriable costs and fish
catch.

Inventory as of June 30, 1998 and September 30, 1997 is summarized as follows:

On May 12, 1998, the Company closed on its fiscal 1998 Title XI application and
received $2.6 million of additional Title XI borrowings for qualified Title XI
projects. The Company is currently authorized to receive up to $20.6 million in
loans under the Title XI program. To date the Company has used $15.0 million of
the authorized Title XI funds.

     The Company utilized proceeds from the initial public offering as described

5.  STOCK OPTION PLANS

1998 Long-Term Incentive Plan

     On January 26, 1998, the 1998 Long-Term Incentive Plan of the Company (the
"1998 Incentive Plan") was approved by the Company's Board of Directors and the
Company's then sole stockholder, Zapata.  The 1998 Incentive Plan provides for
the grant of any or all of the following types of awards: stock options, stock
appreciation rights, stock awards and cash awards.  The Board granted 1,657,360
stock options under the 1998 Incentive Plan at $12.75 per share on January 26,

                                       10
<PAGE>
 
1998.  These granted options vest ratably over three years from the date of
grant and expire ten years from the date of grant.

Non-Management Director Stock Option Plan

     On January 26, 1998, the Non-Management Director Stock Option Plan (the
"Directors Plan") was approved by the Board of Directors and the Company's then
sole stockholder, Zapata. The Directors Plan provides that the initial Chairman
of the Board be granted options to purchase 568,200 shares of common stock and
each other initial non-employee director of the Company will be granted options
to purchase 14,200 shares of common stock at a price determined by the Board.
The Board granted 582,400 stock options under the Directors Plan at $12.75 per
share on January 26, 1998, of which 568,200 were granted to the Chairman of the
Board and 14,200 were granted to the other Board member.  During May 1998 two
additional members were elected to the Board and were each granted 14,200
options at the market price on the date of grant. These granted options vest
ratably over the three years from the date of grant and expire ten years from
the date of grant.

6. CERTAIN TRANSACTIONS AND ARRANGEMENTS BETWEEN THE COMPANY AND ZAPATA

     Upon completion of the Company's initial public offering in April 1998, the
Company and Zapata entered into certain agreements that include the Separation,
Sublease, Registration Rights, Tax Indemnity and Administrative Services
Agreements. The Separation Agreement required the Company to repay $33.3 million
of indebtedness owed by the Company to Zapata contemporaneously with the
consummation of the Company's initial public offering and also prohibits Zapata
from competing with the Company for a period of five years. The Sublease
Agreement provides for the Company to lease its principal corporate offices in
Houston, Texas from Zapata and provides for the Company to utilize certain
shared office equipment for no additional charge. The Registration Rights
Agreement sets forth the rights and responsibilities of each party concerning
certain registration filings and provides for the sharing of fees and expenses
related to such filings. The Tax Indemnity Agreement requires the Company to be
responsible for federal, state and local income taxes from its operations and
the Administrative Services Agreement allows the Company to provide certain
administrative services to Zapata at the Company's estimated cost.

7.  INVESTMENT IN VENTURE MILLING COMPANY
 
     On September 16, 1997, the Company's wholly-owned subsidiary, Venture
Milling Company, a Delaware corporation ("Venture Milling"), sold substantially
all of its assets to an unrelated third party (the "Venture Milling
Disposition"). Venture Milling was primarily in the business of blending
different animal protein products (i.e., fish meal, blood meal and feather meal)
for sale to producers of feed for broilers and other animals with low
nutritional requirements. Venture Milling had revenues and operating income of
$10.4 million and $71,532, respectively, for the quarter ended June 30, 1997,
and $25.3 million and $201,377, respectively, for the nine months ended June 30,
1997. The Venture Milling Disposition resulted in a $531,000 pre-tax loss to the
Company in the fourth quarter of fiscal 1997 and did not have a material impact
on the Company's balance sheet since Venture Milling leased most of the assets
employed in its operations.

8.  LITIGATION
 
     The Company is defending various claims and litigation arising from its
operations.  In the opinion of management, any losses resulting from these
matters will not have a material adverse affect on the Company's results of
operations, cash flows or financial position.

9.  SUBSEQUENT EVENT

Revolving Line of Credit

     On August 11, 1998, the Company entered into a $20.0 million revolving
credit agreement with SunTrust Bank, South Florida, N.A. fulfilling the December
30, 1997 Commitment letter. Under the Credit Facility the Company may make
borrowings in a principal amount not to exceed $20.0 million at any time.
Borrowings under this facility may be used for working capital and capital
expenditures. Interest accrues on borrowings that will be outstanding under the
Credit Facility at the Company's election, either (i) the bank's prime rate less
75 basis points, or (ii) LIBOR plus a margin based on the Company's financial
performance. The Credit Facility is collateralized by all of the Company's trade
receivables, inventory and specific computer equipment. The Company and its
subsidiaries are required to comply with certain financial covenants, including
maintenance of a minimum tangible net worth, debt to tangible net worth ratio,
funded debt to cash flow ratio and fixed charges ratio, and certain other
covenants.

GENERAL

     Omega Protein Corporation ("Omega" or the "Company") and its predecessors
have been a wholly-owned subsidiary of Zapata Corporation ("Zapata"), a publicly
traded company which has shares listed on the New York Stock Exchange, since
1973 when Zapata acquired the Company's operations. The Company is the largest
U.S. producer of protein-rich meal and oil derived from marine sources. The
Company's products are produced from menhaden (a fish found in commercial
quantities), including regular grade and value added specialty fish meals, crude
and refined fish oils and fish solubles. The Company's fish meal products are
used as nutritional feed additives by animal feed manufacturers and by
commercial livestock and poultry farmers. The Company's crude fish oil is sold
to food producers in Europe and its refined fish oil products are used in
aquaculture feeds and certain industrial applications. Fish solubles are sold as
protein additives for animal feed and as organic fertilizers.

     On September 16, 1997, the Company's wholly-owned subsidiary, Venture
Milling Company, a Delaware corporation ("Venture Milling"), sold substantially
all of its assets to an unrelated third party (the "Venture Milling
Disposition"). Venture Milling was primarily in the business of blending
different animal protein products (i.e., fish meal, blood meal and feather meal)
for sale to producers of feed for broilers and other animals with low
nutritional requirements. Venture Milling had revenues and operating income of
$10.4 million and $71,532, respectively, for the quarter ended June 30, 1997,
and $25.3 million and $201,377, respectively, for the nine months ended June 30,
1997. The Venture Milling Disposition resulted in a $531,000 pre-tax loss to the
Company in the fourth quarter of fiscal 1997 and did not have a material impact
on the Company's balance sheet since Venture Milling leased most of the assets
employed in its operations.

     On November 3, 1997, Omega acquired the fishing and processing assets of
American Protein, Inc. ("American Protein"), which operated ten steamers and a
menhaden processing plant in the Chesapeake Bay area, for $14.5 million in cash
(the "American Protein Acquisition"). American Protein's facilities were located
in close proximity to the Company's Reedville, Virginia facility.  Shortly after
completing this transaction, Omega closed the American Protein processing plant
and began integrating its assets into the Company's existing operations.

     On November 25, 1997, the Company purchased the fishing and processing
assets of Gulf Protein, Inc. ("Gulf Protein"), which included six steamers, five
spotter planes and the processing equipment located at the Gulf Protein plant
near Morgan City, Louisiana for $13.6 million in cash and the assumption of
$883,000 in Title XI debt (the "Gulf Protein Acquisition," and together with the
American Protein Acquisition, the "Recent Acquisitions"). In connection with the
Gulf Protein Acquisition, Omega also entered into a five-year lease for the Gulf
Protein plant at a $220,000 annual rental rate. Omega began operations at the
Morgan City, Louisiana plant at the start of the 1998 fishing season.
 
LIQUIDITY AND CAPITAL RESOURCES

     The Company's primary sources of liquidity and capital resources have been
cash flows from operations, borrowings from Zapata, bank credit facilities and
term loans from various lenders provided pursuant to the Title XI of the Marine
Act of 1936 ("Title XI"). These sources of cash flows have been offset by cash
used for capital expenditures (including acquisitions) and payment of long-term
debt. During fiscal 1997, Zapata contributed to the Company as equity $41.9
million of intercompany debt owed to Zapata. As a result, the historical
liquidity and capital resources of the Company may not be indicative of the
Company's future liquidity and capital resources.

     Omega's unrestricted cash balance totaled $41.9 million at June 30, 1998,
up $36.4 million from September 30, 1997 and up $37.7 million from June 30,
1997. This increase was due primarily to the completion of the April 8, 1998
initial public offering of 8,500,000 of the Company's common stock at a gross
price of $16.00 per share and the May 7, 1998 Underwriters exercise of their
option to acquire 1,275,000 additional shares at the same gross price. Of the
9,775,000 total shares sold in the Offering, the Company sold and issued
4,600,000 shares, and Zapata sold 5,175,000 shares.

     Reflecting the Recent Acquisitions, investing activities used $41.5 million
through the third quarter of fiscal 1998 while using $6.8 million during the
corresponding fiscal 1997 period. Excluding the Recent Acquisitions, the Company
anticipates making approximately $18.0 million of capital expenditures in fiscal
1998, a significant portion of which will be used to refurbish vessels, plant
assets and to acquire certain equipment, including a new evaporation unit for
the Reedville, Virginia plant.

      Net financing activities provided $68.5 million during the nine month
period ending June 30, 1998, due primarily to the Company's completed initial
public offering which provided $68.0 million in cash. Financing activities also
provided $2.6 million pursuant to the Title XI guaranteed program. The Company
also assumed $883,000 of Title XI debt in connection with the recent acquisition
of the 

                                       14
<PAGE>
 
Gulf Protein Plant.

     As previously described in Note 1, the Company completed its initial public
offering on April 8, 1998. Subsequent to the Offering, the underwriters elected
to purchase over-allotment options. These issuances generated net proceeds of
approximately $68.0 million (after deducting underwriting discounts and
commissions and offering expenses). Of these proceeds, the Company used
approximately $33.3 million to repay indebtedness to Zapata and $2.1 million to
repay bank indebtedness. Of the $33.3 million indebtedness owed to Zapata, $28.1
million was incurred to fund the cash portion of the purchase price for the
Recent Acquisitions and the balance was primarily incurred to pay the Company's
federal income taxes. The Company has invested the remaining net proceeds in
short-term government securities and interest bearing cash equivalents pending
their use. The Company intends to use these proceeds to fund possible
acquisitions and other capital expenditures as well as for general corporate
purposes.

     On August 11, 1998 the Company entered into a $20.0 million revolving
credit agreement with SunTrust Bank, South Florida, N.A.(the "Credit Facility")
fulfilling the commitment letter dated December 30, 1997. Under the Credit
Facility the Company may make borrowings in a principal amount not to exceed
$20.0 million at any time. Borrowings under this facility may be used for
working capital and capital expenditures. Interest accrues on borrowings that
will be outstanding under the Credit Facility at the Company's election, either
(i) the bank's prime rate less 75 basis points, or (ii) LIBOR plus a margin
based on the Company's financial performance. The Credit Facility is
collateralized by all of the Company's trade receivables, inventory and specific
computer equipment. The Company and its subsidiaries are required to comply with
certain financial covenants, including maintenance of a minimum tangible net
worth, debt to tangible net worth ratio, funded debt to cash flow ratio and
fixed charges ratio, and certain other covenants. As of August 14, 1998, the
Company had no borrowings outstanding under the Credit Facility.
 
     The Company believes that the net proceeds from the Offering, together with
existing cash, cash equivalents, short-term investments and funds available
through its Credit Facility will be sufficient to meet its working capital and
capital expenditure requirements through at least the end of 1999.

INTERIM RESULTS FOR THE THIRD QUARTER ENDED JUNE 30, 1998 AND 1997

     REVENUES. Third quarter fiscal 1998 revenues increased $0.5 million from
$31.0 million in third quarter fiscal 1997 to $31.5 million in the current
quarter. Excluding $10.4 million of revenues attributable to the Venture Milling
operations during the quarter ended June 30, 1997, the comparative quarterly
increase in revenues for June 1998, would be approximately $10.9 or a 53%
increase in revenues. This growth resulted  primarily from a 54.4% increase in
the tons of regular grade meal and a 27.5% increase in the tons of specialty
grade meal shipped, coupled with a 22.3% increase in tons of oil shipped
compared to third quarter fiscal 1997. Additionally, the average selling price
of all the Company's product lines increased 12.2%. The increase in sales
volumes for fish meal and fish oil reflect higher levels of inventory carried
over into fiscal 1998 from the fiscal 1997 fishing season as compared to the
levels of inventory the Company carried over into fiscal 1997 from the fiscal
1996 fishing season and increased demand for the Company's products.

                                       16
<PAGE>
 
     COST OF SALES. Cost of sales, including depreciation and amortization, for
third quarter fiscal 1998 was $19.2 million, a 15.8% decrease from the $22.8
million in the third quarter fiscal 1997. As a percent of revenues, cost of
sales was 61.0% in third quarter 1998 as compared to 73.6% in third quarter
fiscal 1997. Exclusive of the Venture Milling results from third quarter fiscal
1997, the Company's cost of sales as a percentage of revenues for the third
quarter of fiscal 1998 increased 0.3%. Per ton cost of sales were slightly
higher in fiscal 1998 compared to fiscal 1997, due mainly to an increase in
maintenance and vessel related labor costs. Adjusted for the Venture Milling
Disposition, cost of sales as a percentage of net sales for the third quarter
fiscal 1997 would have been 60.7%.

     GROSS PROFIT. Gross Profit increased $4.1 million or 50.0% from $8.2
million in the third quarter fiscal 1997 to $12.3 million in the third quarter
fiscal 1998. As a percentage of revenues, the Company's gross profit margin
increased from 26.4% in the third quarter fiscal 1997 to 39.0% in the third
quarter fiscal 1998. The improvement in gross profit margin in the third quarter
fiscal 1998 was the result of a 27.5%  overall  increase in sales volume of the
Company's higher margin specialty products combined with higher prices received
for the Company's crude oil, refined oil, and the elimination of lower gross
margin sales resulting from the Venture Milling Disposition.
 
     SELLING, GENERAL AND ADMINISTRATIVE PRODUCTS. Selling, general and
administrative expenses increased $168,000 or 9.6%, from $1.7 million in third
quarter fiscal 1997 to $1.9 million in third quarter fiscal 1998 and  increased
as a percentage of revenues from 5.6% in the third quarter fiscal 1997 to 6.1%
in the third quarter fiscal 1998. The comparative quarterly increase in fiscal
1998 over fiscal 1997 was due largely to increased employee related costs.

     OPERATING INCOME. As a result of the factors discussed above, the Company's
operating income of $10.4 million for the three months ended June 30, 1998 was
$3.9 million or 60.1%, greater than the three months ended June 30, 1997.
Operating income as a percent of sales rose to 32.9% for the three months ended
June 30, 1998, as compared to 20.8% for the three  month period ended June 31,
1997.

     INTEREST INCOME (EXPENSE), NET. Interest expense decreased by $538,000,
from $108,000 of interest expense net for the three months ended June 30, 1997
to $430,000 of interest income net for the three months ended June 30,1998. The
decrease in fiscal 1998 net interest expense is due to the Company's investment
of the proceeds from the sale of common stock in the aggregate amount of $40.0
million for the third quarter ended June 30, 1998.

     OTHER INCOME (EXPENSE), NET. Other income (expense) decreased by  $83,000
from $32,000 of other income net, in the third quarter fiscal 1997 to $51,000 of
other expense in the third quarter fiscal 1998. This is primarily due to the
writedown of an investment in a joint venture.

     PROVISION FOR INCOME TAXES. The Company recorded a $2.7 million provision
for income tax for the third quarter fiscal 1997, for a 42.2% effective tax
rate, in comparison to a $4.1 million provision for the third quarter fiscal
1998 resulting in a 38.3% effective tax rate. The effective tax rates
approximate the applicable combined state and federal statutory tax rates for
the respective 

                                       17

periods.

INTERIM RESULTS FOR THE NINE MONTHS ENDED JUNE 30, 1998 AND 1997

     REVENUES. Revenues increased $11.4 million or 14.3%, in the first nine
months of  fiscal 1998 from $79.6 million in 1997 to $91.0 million in fiscal
1998. The improvement was attributed to a 32.6% increase in the tons of fish
meal shipped and a 72.3% increase in the tons of fish oil shipped, coupled with
an 18.6% increase in the overall average selling price of the Company's product
lines. Sales volumes for the Company's fish meal and fish oil products were
significantly higher in the first nine months of fiscal 1998 versus sales
volumes during the first nine months of fiscal 1997 due primarily to higher
levels of inventory carried into fiscal 1998 and increased demand for the
Company's products.  Excluding Venture Milling revenues, the Company had
revenues of $54.3 million for the first nine months of fiscal 1997.

     COST OF SALES. Cost of sales, including depreciation and amortization, for
the first nine months of fiscal 1998, was $55.9 million, a 9.6% decrease from
the $61.9 million for the same period in fiscal 1997. As a percent of revenue,
cost of sales was 61.5% in fiscal 1998 as compared to 77.7% in fiscal 1997.
Exclusive of the Venture Milling Disposition, the Company's cost of sales for
fiscal 1998 as a percentage of revenue decreased 6.3%. However per ton cost of
sales were slightly higher in fiscal 1998 production compared to fiscal 1997,
due mainly to an increase in maintenance and vessel related labor costs.
Adjusted for the Venture Milling Disposition, cost of sales as a percentage of
revenue for fiscal 1997 would have been 67.8%.

     GROSS PROFIT. Gross profit increased $17.4 million or 98.3%, from $17.7
million in fiscal 1997 to $35.1 million in fiscal 1998. As a percentage of
revenues, gross profit increased from 22.3% through the third quarter fiscal
1997 to 38.5% through the third quarter fiscal 1998. The gross profit
performance was primarily a result of an 18.6% increase in the overall selling
prices of the Company's products and the elimination of lower gross margin sales
resulting from the Venture Milling Disposition.

     SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expenses increased  $539,000 or 13.6%, from $4.0 million in
fiscal 1997 to $4.5 million in fiscal 1998. The increases in 1998 were due
primarily to increased employee related costs and consulting fees.
 
     OPERATING INCOME. As a result of the factors discussed above, the Company's
operating income increased to $30.6 million in fiscal 1998, from $13.7 million
in fiscal 1997. As a percentage of revenues, operating income increased to 33.6%
in 1998, from 17.3% in fiscal 1997.

     INTEREST INCOME (EXPENSE), NET. Interest expense increased $55,000 or
11.0%, from $498,000 in fiscal 1997 to $553,000 in fiscal 1998. The increase in
fiscal 1998 net interest expense is due to a $28.1 million intercompany
acquisition loan from Zapata. The interest rate on this loan was 8.5%. This loan
was prepaid in full with a portion of the net proceeds from the Company's
initial public offering.

                                       18
<PAGE>
 
     OTHER INCOME (EXPENSE), NET. Other expense increased $145,000 in 1998. This
is primarily due to the writedown in the investment in a joint venture.

     PROVISION FOR INCOME TAXES. The Company recorded an $11.3 million provision
for income taxes in fiscal 1998. This represents an effective tax rate of 37.7%
in comparison to a $5.1 million tax provision in fiscal 1997, representing an
effective tax rate of 38.3%. The effective tax rates approximate the applicable
combined state and federal statutory tax rates for the respective periods.

Seasonal and Quarterly Results

     The Company's menhaden harvesting and processing business is seasonal in
nature. The Company generally has higher sales during the menhaden harvesting
season (which includes the third and fourth quarter of each fiscal year) due to
increased product availability, but prices during the fishing season tend to be
lower than during the off-season. As a result, the Company's quarterly operating
results have fluctuated in the past and may fluctuate in the future. In
addition, from time to time the Company defers sales of inventory based on
worldwide prices for competing products that affect prices for the Company's
products which may affect comparable period comparisons.

Year 2000

     The Company has converted most of its computer information systems enabling
proper processing of transactions related to the year 2000 and beyond.  The cost
of conversion was immaterial and has been expensed.  The Company continues to
evaluate its systems and expects that all of its systems will be compliant prior
to the year 2000.

PART II.  OTHER INFORMATION
 
ITEM 1.  LEGAL PROCEEDINGS

     The Company is involved in various claims and disputes arising in the
normal course of business, including claims made by employees under the Jones
Act which generally are covered by the Company's insurance. The Company believes
that it has adequate insurance coverage for all existing matters and that the
outcome of all pending proceedings, individually and in the aggregate, will not
have a material adverse effect upon the Company's business, results of
operations, cash flows or financial position.

ITEM 2.  CHANGES IN SECURITIES

     In April and May, 1998, the Company sold 4,600,000 shares of its common
stock for an aggregate offering priced of $73.6 million. Also pursuant to the
Registration Statement,  Zapata, as a selling stockholder, sold 5,175,000 shares
of common stock of the Company for an aggregate offering price of $82.8 million.
The net Offering proceeds to the Company and Zapata, as selling stockholder,
after underwriting discounts and commissions expenses was $68.0 million and
$77.2 million, respectively. All disbursements from the aggregate proceeds of
the Offering (including expenses) were direct or indirect payments to non-
related parties.

     On April 8, 1998, the Company used approximately $33.3 million of its net
proceeds from the Offering to repay an acquisition loan and certain other
indebtedness owed Zapata and approximately $2.1 million to repay a bank loan.
The Company anticipates using the balance of the net proceeds for capital
expenditures (including possible acquisitions), working capital and general
corporate purposes. All unused net proceeds have been invested in cash, cash
equivalents and short-term investments. The use of the proceeds from the
Offering to date does not represent a material change in the use of the proceeds
described in the prospectus included in the Registration Statement. As
represented below, on August 11, 1998 the Company entered into a Revolving
Credit Agreement with SunTrust Bank of South Florida, N.A. The Revolving Credit
Facility Agreement prohibits the Company from paying or declaring dividends in
excess of 50% of its consolidated net income (as defined therein).
 
ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

     The Company was formed on January 26, 1998 to effect the reincorporation of
Marine Genetics Corporation ("Marine Genetics") from a Delaware corporation to a
Nevada corporation and to change its name to Omega Protein Corporation. In
January 1998, the Company's sole stockholder, Zapata, provided its written
consent with respect to various matters, including the following actions: (1)
the election of Joseph L. von Rosenberg III, Avram Glazer and Malcolm Glazer as
the Company's directors; (2) the merger of the Company with Marine Genetics
Corporation; (3) the approval of the Company's 1998 Long-Term Incentive Plan;
and (4) the approval of the Company's 1998 Non-Employee Directors' Stock Option
Plan.

the aforementioned transaction unless payment pursuant to the Note, Deed of
Trust and Security Agreement and Ship Mortgage shall be guaranteed
unconditionally by the Guarantor. This Guaranty Agreement is executed and
delivered by the Guarantor in order to induce the Government to enter into the
aforementioned transaction with the Payor and Payee.

either the Note, Deed of Trust and Security Agreement or the ship Mortgage to be

Government presently existing or which may in any manner or means hereafter be
incurred, including any further loans and advances made to Payor by the
Government under the provisions hereof, shall be promptly paid in full when due,
in United States currency, in accordance with the provisions governing such
payment. This Guaranty is unconditional and absolute and if for any reason such
sums, or any part thereof, shall not be paid promptly when due, the Guarantor
will immediately pay the same to the Government pursuant to the provisions
governing such payment, regardless of any defenses or rights of setoff or
counterclaims which the Payor may have or assert, and regardless of whether the
Payee or the Government shall have taken any steps to enforce any rights against
the Payor or any other person to collect such sums, or any part thereof, and
regardless of any other condition or contingency. The Guarantor also agrees to
pay the Government the costs and expenses of collecting such sums, or any part
thereof, or of enforcing this Guaranty Agreement, including attorneys' fees.

     health or safety statutes, ordinances, orders, rules, regulations or
     requirements, and have removed in compliance with all applicable
     environmental requirements from and off the Premises all hazardous
     materials, substances, petroleum products and waste.

     3. There are no statutes, orders, rules, regulations or agreements relating
     to environmental matters requiring any work, repairs, feasibility studies,
     remedial investigations, clean up costs, construction or capital
     expenditures, or any other response costs with respect to the Premises, nor
     have the Borrower or any other individual or entity received any notice of
     any of the same.

     4. No hazardous or toxic materials, substances, pollutants, contaminants or
     wastes have been released, spilled, leaked, poured, dumped, deposited,

     remedial investigations, feasibility studies, clean up costs or other
     response costs pending or threatened, relating to the ownership, use,
     maintenance or operations of the Premises, nor is there any basis for such
     law suits, claims, proceedings or investigations being instituted or filed.

II  Notwithstanding any matter shown in ENPRO's January 15, 1996, Phase 1
     Environmental Assessment Report:

     1. The Borrower and/or any other individual or entity will operate the
     Premises and shall at all times receive, handle, use, store, treat, ship
     and dispose of all hazardous materials, substances, petroleum products and
     waste in strict compliance with all applicable environmental, health or
     safety statutes, ordinances, orders, rules, regulations or requirements,
     and will remove in compliance with all applicable environmental
<PAGE>
 
     requirements from and off the Premises all hazardous materials, substances,
     petroleum products and waste.

     2. The Borrower further covenants that it will promptly notify the
     Government of any fact or event which affects, alters or limits the
     representations and warranties made in the preceding sections, above, and

     to information relating to the Borrower's compliance with this Agreement.

The foregoing representations and warranties shall survive the execution of this
Agreement and any closing occurring under any of the Loan Documents (defined

agree to defend and indemnify the Government against and hold it harmless from

exemplary, actual, compensatory and punitive), penalties, expenditures, costs
and legal or other expenses which the Government may suffer or incur as a direct
or indirect consequence of any of the following:

     Government of any of its rights, remedies, liens, interest or discretion
     under this Agreement or any of the other Loan Documents, against the
     Borrower and the Guarantor or any other person or entity, or in or to any
     property now or hereafter constituting collateral for or on account of any
     loans or obligations of the Borrower and the Guarantor;

          Government; except that the Borrower and the Guarantor shall not be
          obligated to pay any judgment which any court of competent
          jurisdiction may render against the Government upon an express finding

Case No. OG-G-867

                       TITLE XI FINANCIAL AGREEMENT

  THIS TITLE XI FINANCIAL AGREEMENT (hereinafter, the "Financial Agreement")
dated May 12, 1998, is made and entered into by Omega Protein, Inc., formerly
Zapata Protein (USA), Inc., 1514 Martens Drive, Hammond, Louisiana 70401
(hereinafter, the "Borrower"), Omega Protein Corporation, formerly Marine
Genetics Corporation, 1717 St. James Place, Suite 550, Houston, Texas 77056,
(hereinafter, the "Guarantor"), and the UNITED STATES OF AMERICA, acting by and
through the Secretary of Commerce, (hereinafter, the "Government"),

  WHEREAS, heretofore, the Government, pursuant to the Fisheries Obligation
Guarantee Program, as provided in 46 USC (S)1271, et. seq., (hereinafter "FOG"),
made, entered into, and delivered certain agreements and covenants, as contained
in the Commitment to Guarantee Note dated January 28, 1988, as amended on
November 15, 1988, and the Commitment to Guarantee Note executed on November 22,
1988, and further amended by an Approval Letter dated January 22, 1998,

its guarantee of Borrower's loan from the Bank includes all of the items listed
below:

  1.  THE EQUIPMENT:  The Borrower will provide to the Government security
interests, evidenced by UCC filings, in the full amount of the Guaranteed Note,
on all of the property described below (hereinafter, the "Equipment");

  All fisheries unloading, processing, holding, and distribution equipment of
  whatsoever nature, now or at any time in the future, together with all
  accessories, improvements, replacements, substitutions, or additions thereto,
  used for the Borrower's  fisheries operations on the properties which secure
  the Promissory Note and any other debt to the Government, or on any other

  all hand and power tools; and all office equipment, all together with all
  associated equipment, machinery, parts, tools, purse boats, or other items of
  whatsoever nature and whether fixed or unfixed to the aforementioned property

  THIS EXCLUDES ONLY SUCH FIRST UCC SECURITY INTERESTS TO THIRD PARTIES as may
be necessary and appropriate to secure credit from such parties for the specific
purpose of purchasing specific equipment (hereinafter "Purchase-Money
Equipment").  In such cases, the Borrower agrees to the following:

       (a)  To give to the Government UCC security interests on the Purchase-
Money Equipment second only to the first interests pledged to the lenders of the
purchase-money (hereinafter the "Purchase-Money UCC security interests"); and

       (b)  That the amount secured by the Purchase-Money UCC security interests
shall not exceed the specific purchase cost of said equipment; and

       (c)  The term of the credit secured to buy the Purchase-Money Equipment
(and likewise, the duration of the Purchase-Money UCC security interests) shall
not exceed an ordinarily prudent commercial term; and

       (d)  No other Equipment or rights shall be secured by the Purchase-Money
UCC security interests; and

       (e)  Upon full repayment of the amounts secured by the Purchase-Money
Equipment, as reflected in the Purchase-Money UCC security interests, these
interests shall be satisfied and the Government's second UCC security interest
will ascend to first priority.

  THE EQUIPMENT SHALL BE INVENTORIED sufficiently to describe with certainty in
the security agreement and associated UCC filing.  The inventory shall be valued
by appraisers acceptable to the Government.  The inventory and appraisals shall
be at the Borrower's cost and paid before this loan is closed, unless this
requirement is specifically waived by the Government.

  THE UCC SECURITY AGREEMENT SHALL CONTAIN the following provisions:

       (a)  That the Government may enter upon any premises where the Equipment
may be located and marshal, secure, protect, and do all things necessary to
preserve the Equipment immediately upon the Borrower's default, but before any
judicial action regarding such default; and

       (b)  Such other provisions as the Government deems necessary to protect
its interest; and

       (c)  Omega Protein, Inc., formerly Zapata Protein (USA), Inc., and Omega
Protein Corporation, formerly Marine Genetics Corporation, agree that neither
corporation will enter into 

                                       3
<PAGE>
 
any transaction or agreement with any party which will result in that party
having a secured interest in the Equipment unless that party first enters into a
written agreement, with provisions acceptable to the Government, that:

          (i)  Except for purchase money lien holders, recognize the
Government's senior interest in, and sole rights to, the equipment or proceeds
of the Equipment's liquidation; and

          (ii)  Agree not to interfere in any way with, but instead to cooperate
in all reasonable ways with, the Government entering upon any property owned or
leased by the Borrower in order to marshal, secure, protect, and do all things
necessary to preserve the Equipment.

  2.  THE REAL PROPERTY includes:

A Deed of Trust in the full amount of the FOG Debt, on such real property, as
more fully described in Exhibit 1, attached, owned by Borrower, together with
all improvements thereon which comprise the Borrower's fisheries processing
facility in Reedville, Virginia.

  3.  THE GUARANTEE:  An unconditional guarantee of repayment of the FOG Debt
will be given to the Government by Omega Protein Corporation, formerly Marine
Genetics Corporation, (the "Guarantor").

                  ARTICLE III. ADDITIONAL COLLATERAL

  1.  Individual Transferable Quotas:  Should a limited fisheries access system
be initiated at some future date under which the Borrower is granted a
transferable fishery conservation and management allocation (including, but not
limited to, allocations, permits, quotas, licenses, cage tags, or any other
fisheries access restriction or right, however characterized, of whatsoever
nature) affecting, necessary for, or in any other way, however characterized,
associated with any of the property included in the Collateral, the Borrower
agrees to grant to the Government a full senior security interest in such
allocation by whatsoever means deemed by the Government to be appropriate
(including, but not limited to, the Borrower's execution of security agreements
and the filing of financing statements under the UCC).  Further, if the Borrower
fails to do so, the Borrower agrees that the Government may use, for the purpose
of executing and otherwise perfecting whatever documents may be required to
effect the grant to the Government of such a full security interest in such
fisheries conservation and management allocation, the attorney-in-fact authority
conferred upon the Government by ARTICLE XI of this agreement.

  2.  OTHER COLLATERAL:  Any new, different, substitute or other collateral
which may, from time to time, be provided by Borrower or Guarantor to the
Government, will be subject to all of the covenants and provisions of all of the
documents executed in connection with this transaction, including, but not
limited to the Deed of Trust and Security Agreement, the Ship Mortgage, this
Financial Agreement, the Guaranteed Note, the Promissory Note, and UCC security
interests.

for erroneous calculations and for payments required under the Note and other
security documents, which are delinquent.

       (c)  THE PAYMENT OF THE INITIAL FEE is being made to the Government
concurrently with the execution and delivery of the Guaranteed Note, the receipt
whereof by the Government is hereby acknowledged, and covers a twelve-month

premium charges hereunder (other than deficient premium charges) shall cease as
of the last time the Government shall have been obligated to make payment under

       (f)  IF AT THE TIME OF TERMINATION of the Guarantee the Government holds

accordance with this SECTION (or the time for application of which has not

Government as collateral security for the payment of the Note and any amounts
due under the security documents, and any sum due to the Government if the
Guarantee shall terminate pursuant to payment of the Guarantee by the Government
or if there is a failure of the holder of the Guaranteed Note to properly demand
payment of the Guarantee from the Government within 60 days of notification of a
default under the Guaranteed Note by the Government and the Guarantee is
terminated.  If payment of the Guarantee shall have been demanded and shall not
have been made, for any reason (other than under the conditions under which the
Government is not required to make payment of the Guarantee) within the thirty-
day period therefor, any excess fee or any annual fee which has not been applied

indemnity.

proceeds will be applied as directed by the GOVERNMENT.  If an Event of Default
exists, the GOVERNMENT shall retain such insurance and, if such Event of Default

     (f)  IN THE EVENT OF AN ACTUAL OR CONSTRUCTIVE TOTAL LOSS, or an agreed or
compromised total loss of or in case of requisition of title to the VESSEL, all

discretion of the GOVERNMENT, and upon notice to the BORROWER, assign to any
person, firm, or corporation executing a surety or guarantee bond or other
agreements, to save or release the VESSEL from such arrest, all right, title,
and interest of the GOVERNMENT in and to said insurance covering said loss,
damage, or expense, as collateral security to indemnify against liability under

certified copy of this Mortgage with the VESSEL's papers on board the VESSEL,

"NOTICE OF MORTGAGE:  This VESSEL is covered by a First Preferred Ship Mortgage
given to the United States of America, under authority of the Ship Mortgage Act,
1920, as amended.  Under the terms of said Mortgage, neither the owner of this
VESSEL, any charterer, the Master of this VESSEL, nor any other person has any
right, power, or authority to create, incur, or permit to be imposed upon the
VESSEL any liens, maritime or otherwise, other than the lien of said Mortgage
and liens for crew's wages, for wages of a stevadore when employed directly by
the owner, the operator, master or agent of this VESSEL, for salvage, or the
extent there are liens subordinate to the Mortgage, other liens incident to
current operation for repairs"

     SECTION 5:   NOTICES TO THE GOVERNMENT:

     (a)  OF ACTION AGAINST VESSEL:  In the event that a suit or claim is filed
against the VESSEL, or if the VESSEL shall be levied upon or taken into custody,
or detained by any proceeding in any court, or tribunal, the BORROWER will,
within 72 hours, notify the GOVERNMENT by telegram or facsimile, confirmed by
letter, and the BORROWER will, within fifteen (15) days thereafter, cause the
VESSEL to be discharged.

the BORROWER shall furnish the GOVERNMENT full information regarding any
casualties or other accidents or damage to the VESSEL, including copies of any
supporting documents, i.e., accident reports, claims, etc.; provided that such
obligation shall not exist with respect to any casualty, accident, or damage
that is less than $50,000 in amount, or is covered by insurance (including any
deductible permitted by this Mortgage).

     SECTION 6:   MAINTENANCE AND INSPECTION COSTS:

     (a)  VESSEL MAINTENANCE:  At all times, at the BORROWER'S own cost and
expense, the BORROWER will maintain and preserve the VESSEL in as good
condition, working order and repair as on the date of this Mortgage, ordinary
wear and tear excepted; provided, however, if subsequent to the date of this
Mortgage, the VESSEL is reconstructed or reconditioned, the BORROWER will keep
the VESSEL in as good condition, working order, and repair as the VESSEL was on
the date said reconstruction or reconditioning was completed, ordinary wear and
tear excepted. In addition to the foregoing, the BORROWER will keep the VESSEL
in as good condition as will enable her to pass such inspection as may be
required by marine underwriters as a condition of their writing such insurance
in such amounts as are required under this Mortgage.

     (b)  INSPECTION OF VESSEL: The BORROWER shall afford the GOVERNMENT or its
authorized representatives full and complete access to the VESSEL, in port or at
sea, at such times as the GOVERNMENT, in its sole discretion, may require, for
the purpose of inspecting or valuing the VESSEL, her cargo, log, and papers.

     (c)  BORROWER TO PAY THE COST OF ANNUAL INSPECTIONS, audits or appraisals,
provided for in Paragraphs 6(a) and 6(b), immediately above, within 30 days of
the GOVERNMENT's demand and all such amounts disbursed by the GOVERNMENT for
such purpose shall, until fully repaid by the BORROWER, be added (payable upon
the GOVERNMENT'S demand) to the BORROWER'S Promissory note to the GOVERNMENT and
shall earn interest at the same rate as the other principal of the BORROWER'S
Promissory Note and shall be secured by the Ship Mortgage and other securities
which secure the BORROWER'S Promissory Note to the GOVERNMENT.

     SECTION 7.   TAXES & FEES:



                                       5

time all taxes, assessments, GOVERNMENTAL charges, fines, and penalties lawfully
imposed on the VESSEL.

     (b)  The BORROWER may fail to pay and discharge any taxes, assessments,
governmental charges, fines and penalties (together, "Charges") imposed on the

reimburse the GOVERNMENT for any and all expenditures which the GOVERNMENT may
elect to make from time to time to protect the security granted hereunder (in
the event of the BORROWER'S failure to do so), including, without limitation of
the foregoing, payment of taxes, repairs, insurance premiums, the discharge of
any lien, libel or seizure of the VESSEL, and expenses incurred by the
GOVERNMENT in retaking the VESSEL; and any such payment made by the GOVERNMENT
shall be for the account of the BORROWER, and the making thereof by the
GOVERNMENT shall not cure the BORROWER'S default in that regard nor constitute a
waiver of any right or remedy granted to the GOVERNMENT hereunder, and all sums
so expended by the GOVERNMENT or any liability incurred by it shall be
immediately due and payable and shall be deemed to be an indebtedness of the
BORROWER and secured by this Mortgage, and until paid shall bear interest at the
same rate as that provided in the Promissory Note.

     SECTION 9:   GOVERNMENT'S PRIOR WRITTEN CONSENT REQUIRED:  The BORROWER
shall not, without prior written consent of the Chief, Financial Services
Division, National Marine Fisheries Service, take any of the following actions:

     (a)  SELL, MORTGAGE, TRANSFER, OR CHARTER THE VESSEL, and any such written
consent obtained from the GOVERNMENT to any one sale, mortgage, transfer, or
charter, shall not be construed to be a waiver of this provision with respect to
any subsequent proposed sale, mortgage, transfer, or charter.  Any such sale,
mortgage,  transfer, or charter of the VESSEL shall be subject to the provisions
of this Mortgage and to the lien it creates.

     (b)  REMOVE, ATTEMPT TO REMOVE, OR ALLOW THE VESSEL TO BE MOVED beyond the
Exclusive Economic Zone (EEZ) of the United States of America, as defined in 16
USC (S)1802(6)/1/, with the further limitation that the VESSEL may not be moved
to or from zones contiguous to the territorial seas of the Commonwealth of
Puerto Rico, U.S. Virgin Islands or Northern Mariana Islands without prior
written consent of the Chief, Financial Services Division, (NMFS).  Further, it

GOVERNMENT upon the VESSEL owner.

     (c)  TRANSFER PORT OF DOCUMENTATION OF THE VESSEL.

     SECTION 10.  COMPLIANCE WITH FEDERAL SHIP MORTGAGE ACT: The BORROWER will
comply with and satisfy all the provisions of the Ship Mortgage Act, 1920, as
amended, 46 USC 31301, et seq. in order to establish and maintain this Mortgage
as a Preferred Ship Mortgage upon the VESSEL.

     SECTION 11.  OPERATING RESTRICTIONS:

     (a)  DOCUMENTATION:  The BORROWER will keep the VESSEL documented under the
laws of the United States.

territorial sea of the United States, the Commonwealth of Puerto Rico, the
commonwealth of the Northern Mariana Islands (to the extent consistent with the
Covenant and the United Nations Trusteeship Agreement), and the United States
overseas territories and possessions.  The Exclusive Economic Zone extends to a
distance 200 nautical miles from the baseline from which the breadth of the
territorial sea is measured.  In cases where the maritime boundary with a
neighboring State remains to be determined, the boundary of the Exclusive
Economic Zone shall be determined by the United States and other State concerned
in accordance with equitable principles.

     (b)  LAWFUL OPERATION: The BORROWER will not cause or permit the VESSEL to
be operated in any manner contrary to law or contrary to any rules and
regulations which may from time to time be prescribed pursuant to law.

     (c)  IF THE GOVERNMENT'S WRITTEN CONSENT TO REMOVE THE VESSEL BEYOND THE
LIMITS OF THE UNITED STATES IS OBTAINED, the BORROWER will not abandon the
VESSEL in a foreign port.  The BORROWER will not engage in any unlawful trade or
violate any law or carry any cargo that will expose the VESSEL to penalty,
forfeiture, or capture, and will not do, or suffer or permit to be done,
anything which can or may injuriously affect the documentation of the VESSEL
under the laws and regulations of the United States.

     (d)  UPON DEMAND BY THE GOVERNMENT TO THE MASTER OF THE VESSEL or the
BORROWER, the BORROWER will return the VESSEL to the EEZ of the United States
and, if the GOVERNMENT so demands, to a port of call chosen by the GOVERNMENT,
thereby revoking any prior consent extended by the GOVERNMENT with respect to
operation of the VESSEL outside the EEZ of the United States.

     SECTION 12.  SEVERABILITY CLAUSE:  In the event that this Mortgage, the
Notes, or any provisions hereof or thereof shall be deemed invalid in whole or
in part by reason of any present or future law of the United States or any
decision of any authoritative court, said invalidity or unenforceability shall
not render any other provision(s) herein unenforceable or invalid; and the
remaining provision(s) shall remain in full force and effect.

     SECTION 13.  POWER OF ATTORNEY:  If the documents at any time held by the
GOVERNMENT are deemed by the GOVERNMENT, for any reason, to be insufficient to
carry out the true intent and spirit of this Mortgage and the Notes, then from
time to time the BORROWER will execute on its own behalf such other and further
assurances and documents as in the opinion of counsel for the GOVERNMENT may be
required more effectually to subject the VESSEL to the payment of the principal
sum of the Notes, together with interest thereon, as in the Notes and this
Mortgage.  Upon failure of the BORROWER so to do, the GOVERNMENT may execute any
and all such other and further assurances and documents, for and in the name of
the BORROWER and the BORROWER hereby irrevocably appoint the GOVERNMENT the
agent attorney-in-fact of the BORROWER so to do.  Any expenses of the GOVERNMENT
in connection with the foregoing shall be a debt due from the BORROWER to the
GOVERNMENT in payment thereof and shall be secured by the lien of this Mortgage.

proceeding or pursuant to subsection (e) following, all costs, expenses,
charges, damages, or losses by reason of such use; and if at any time the
GOVERNMENT shall avail itself of the right herein given it to retake the VESSEL

or whether any Default has occurred, or as to the propriety of the sale, or as
to the application of proceeds thereof.

rate.

such proceedings as to them or any of them as may seem proper towards the
defense of such suit and the discharge of such lien, and all expenditures made
or incurred by them or any of them for the purpose of such defense or discharge
shall be a debt due from the BORROWER to the GOVERNMENT and payment thereof
shall be secured by the lien of this Mortgage.

     (c)  JURISDICTION AND VENUE:  The BORROWER hereby expressly and irrevocably

addition to every other power and remedy herein specifically given or now or
hereafter existing at law, in equity, admiralty, or by statute, and each and
every power and remedy whether specifically herein given or otherwise existing
may be exercised from time to time and as often and in such order as may be
deemed expedient by the GOVERNMENT, and shall not be construed to be a waiver of
the right to exercise at the same time or thereafter any other power or remedy.
No delay or omission by the GOVERNMENT in the exercise of any right or power or
in the pursuance of any remedy occurring upon any Event of Default shall impair
any such right, power, or remedy or be construed to be a waiver of any such
Event of Default or to be any acquiescence therein; nor shall the acceptance by
the GOVERNMENT of any security or of any payment of or on account of the Note
maturing after any Event of Default or of any payment on account of any past
Event of Default be construed to be a waiver of any right to take advantage of
any future Event of Default or of any past Event of Default not completely cured
thereby.

     (b)  THE GOVERNMENT, IN ADDITION TO SUCH OTHER RIGHTS OR REMEDIES it may
have, shall have the right, in its discretion, to take any and all action
authorized by Sections 1105(c) and 1105(e) of Title XI and, to the extent not in
express conflict with the action authorized by said Sections, or with this
SECTION, any and all action provided for in or authorized or permitted by or in
respect of this Mortgage, the Notes, Collateral or Security, and Policies of
Insurance (including all action provided for in or authorized or permitted by or
in respect of any or all said documents by the GOVERNMENT).

     SECTION 9.   GOVERNMENTAL FAILURE TO JUDICIALLY ENFORCE THE PROVISIONS OF
THESE DOCUMENTS DOES NOT INVALIDATE SAME: Where the GOVERNMENT shall have
proceeded to enforce any right, power, or remedy under this Mortgage, or any
other document which has been executed by the BORROWER, by foreclosure, entry,
or otherwise, and such proceedings shall have been discontinued or abandoned for
any reason, or shall have been determined adversely to the GOVERNMENT, then and
in every such case the BORROWER and the GOVERNMENT shall be restored to their
former positions and rights hereunder with respect to the property subject or

          This Revolving Credit Note (this "Note") is the Note defined in, and
evidences Advances incurred pursuant to, that certain Revolving Credit
Agreement, dated as of August 11, 1998, by and among the Company and the Lender
(as amended, restated, modified and supplemented from time to time, the "Credit

complete description of such terms and conditions, including, without
limitation, the circumstances under which the maturity of this Note may or will

any Advance under the Credit Agreement to an account of the Company or payment
under a Letter of Credit Obligation to an account of the Company or any
Guarantor or recording such amount on the grid schedule attached hereto shall,
in the absence of manifest error, constitute presumptive evidence of such
Advance or payment.  Such account records or grid schedule shall constitute, in
the absence of manifest error, presumptive evidence of principal amounts
outstanding and repayments made under this Note and the Credit Agreement, at any
time and from time to time, provided that the failure of the Lender to record on

payment shall not affect the obligation of the undersigned to repay such amount,
together with interest thereon, in accordance with this Note and the Credit
Agreement.

          Failure or forbearance of the Lender to exercise any right hereunder,
or otherwise granted by the Credit Agreement or by law, shall not affect or
release the liability of the Company hereunder, and shall not constitute a
waiver of such right unless so stated in writing by such of the Lenders as are
required under the Credit Agreement to effect such waiver.  THIS NOTE SHALL BE
DEEMED TO BE MADE UNDER, AND SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED
BY, THE LAWS OF THE STATE OF FLORIDA.  TIME IS OF THE ESSENCE OF THIS NOTE.

is or hereinafter will be granted by the Company pursuant to transactions or
agreements in form and substance satisfactory to the Lender.

          (b) Property in Possession.  In addition, as collateral security for
the prompt and complete payment and performance when due of the Obligations and
in order to induce the Lender as aforesaid, the Lender is hereby granted a lien
and security interest in all property of the Company held by the Lender,

          (c) The Company intends and hereby acknowledges that the grant of a
security interest in the Collateral to the Lender conveys a security interest in

Collateral is owned individually, jointly or severally by the Company.

          3.  Right of Lender; Limitations on the Lender's Obligations;
              License.

          (a) The Company Remains Liable.  It is expressly agreed by the Company
that,



                                      -7-
<PAGE>
 
anything herein to the contrary notwithstanding, the Company shall remain liable
under each of its Contracts and each of its Licenses to observe and perform all
the conditions and obligations to be observed and performed by it thereunder and
the Company shall perform all of its duties and obligations thereunder, all in
accordance with and pursuant to the terms and provisions of each such Contract
or License. The Lender shall not have any obligation or liability under any
Contract or License by reason of or arising out of this Agreement or the
granting to the Lender of a security interest therein or the receipt by the
Lender of any payment relating to any Contract or License pursuant hereto, nor
shall the Lender be required or obligated in any manner to perform or fulfill
any of the obligations of the Company under or pursuant to any Contract or
License, or to make any payment, or to make any inquiry as to the nature or the
sufficiency of any payment received by it or the sufficiency of any performance
by any party under any Contract or License, or to present or file any claim, or
to take any action to collect or enforce any performance or the payment of any
amounts which may have been assigned to it or to which it may be entitled at any
time or times.

          (b) Direct Collection.  The Lender may at any time, on or after the
Acceleration Date, open the Company's mail and collect any and all amounts due
from Account Debtors, and notify Account Debtors of the Company, parties to the
Contracts of the Company, obligors of Instruments of the Company and obligors in
respect of Chattel Paper of the Company that the Accounts and the right, title
and interest of the Company in and under such Contracts, such Instruments and
such Chattel Paper have been assigned to the Lender and that payments shall be
made directly to the Lender or to a lockbox designated by the Lender.  Upon the
request of the Lender made at any time on or after the Acceleration Date, the
Company will so notify such Account Debtors, parties to such Contracts, obligors
of such Instruments and obligors in respect of such Chattel Paper.  The Lender
also may at any time on or after the Acceleration Date, in its own name or in
the name of the Company, communicate with such Account Debtors, parties to such
Contracts, obligors of such Instruments and obligors in respect of such Chattel
Paper to verify with such Persons to the Lender's sole satisfaction the
existence, amount and terms of any such Accounts, Contracts, Instruments or
Chattel Paper.

          (c) Test Verifications.  Upon reasonable prior notice to the Company
(unless an Event of Default has occurred, in which case no notice is necessary),
the Lender shall have the right to make test verifications of the Accounts and
physical verifications of the Inventory in any reasonable manner and through any
reasonable medium that it considers advisable, provided however, that (i) the
Lender must choose a manner and medium which will not be conspicuous to the
clients and customers of the Company, (ii) the Company agrees to furnish all
such assistance and information as the Lender may require in connection
therewith, and (iii) in the event the Lender exercises its right to make test
verifications at a time when no Event of Default has occurred or is continuing,
the Lender shall pay all expenses associated with such test verification.

          4.  Representations, Warranties and Covenants.  The Company hereby
represents, warrants and covenants that:

          (a) Locations, Name of Debtor, Etc.  All of the Inventory is located
at the




                                      -8-
<PAGE>
 
places specified in Schedule 1 attached hereto and such location is an owned,
leased or bailment location as specified in Schedule 1 attached hereto. The
correct corporate name, the principal place of business and the chief executive
office of the Company and the places where the Company's books and records
concerning the Collateral are currently kept are set forth in Schedule 2
attached hereto and made a part hereof. All records concerning Accounts and
General Intangibles and all originals of any Documents, Instruments or Chattel
Paper are located at the addresses set forth on Schedule 2 and none of the
Accounts or General Intangibles is evidenced by a promissory note or other
Instrument except for notes or other Instruments which have been delivered to
the Lender.

          (b) Accounts Accurate.  The amount represented by the Company to the
Lender in the most recent financial statements delivered to the Lender and from
time to time in the future as the amount owing by each Account Debtor is within
five percent (5%) of the true and correct amount actually owing by such Account
Debtor thereunder, and the aggregate amount owing by all Account Debtors in
respect of all Accounts is within five percent (5%) of the true and correct
amount actually owing by such Account Debtors thereunder.

          (c) Exclusive Possession and Control.  The Company has exclusive
possession and control of the Inventory, except for (i) Inventory temporarily in
transit with common or other carriers, (ii) Inventory located at (A) a location
listed on Schedule 1 specifying that the Company does not have exclusive
possession and control or (B) such other locations as are permitted by the
Lender pursuant to Section 5(b) of this Agreement, and (iii) Inventory located
at the places of business of the Company's customers.

          (d) Legal Owner.  The Company is the legal and beneficial owner of, or
has rights to use, the Collateral free and clear of all Liens other than
Permitted Liens and, in the case of Patents or Trademarks, free and clear of all
licenses, registered-user agreements and covenants not to sue third persons.
The Company has not, during the five (5) years preceding the date hereof, been
known as or used any other corporate, trade or fictitious name, except as
disclosed on Schedule 3 hereto, nor acquired all or substantially all the
assets, capital stock or operating unit of any Person, except as disclosed on
Schedule 3 hereto, and each predecessor in interest of the Company during the
five (5) years preceding the Closing Date is disclosed on Schedule 3 hereto.

          (e) No Security Agreement.  No effective security agreement, financing
statement, equivalent security or lien instrument or continuation statement
covering all or any part of the Collateral is on file or of record in any public
office, except (i) such as may have been filed by the Company in favor of the
Lender pursuant to this Agreement, and (ii) those filed by the United States to
secure the Title XI Financing.

          (f) Financing Statements.  This Agreement creates in favor of the
Lender a legal, valid and enforceable Lien on the Collateral, securing the
payment of the Obligations.  When financing statements have been filed in the
appropriate offices under the UCC in the




                                      -9-
<PAGE>
 
locations listed on Schedule 4, the Lender will have a fully perfected first
priority Lien on the Collateral, except where limited or prohibited by the terms
of a Contract, provided however, that with regard to any Lien on the collateral
securing any Title XI Financing, a description of such collateral and the
respective locations to be attached hereto as Schedule 4(f), the Lender will
have a fully perfected security interest subordinate only to any security
interest securing such Title XI Financing. When the Trademark Security Agreement
has been filed in the United States Patent and Trademark Office, the Lender will
have a fully perfected first priority Lien on the Collateral, to the extent such
Lien may be perfected by the filing of such agreements in the United States
Patent and Trademark Office.

          (g) No Governmental Approval.  No Governmental Approval, and no notice
to any governmental agency is required either (i) for the grant of a Lien by the
Company in the Collateral pursuant to this Agreement or (ii) the exercise by the
Lender of the rights provided for in this Agreement or the remedies in respect
to the Collateral pursuant to this Agreement other than any  notice and consent
required pursuant to the Title XI Financing.

          (h) Trademarks.  The Trademarks and any trademarks in which the
Company has been granted rights pursuant to Trademark Licenses, are subsisting
and have not been adjudged invalid or unenforceable; each of the Trademarks and
any trademark in which the Company has been granted rights pursuant to Trademark
Licenses, is valid and enforceable; to the best of the Company's knowledge, no
claim has been made that the use of any of the Trademarks or any trademark in
which the Company has been granted rights pursuant to the Trademark Licenses
does or may violate the rights of any third person; upon registration of its
Trademarks, the Company will use for the duration of this Agreement, proper
statutory notice in connection with its use of the Trademarks; and the Company
will use, for the duration of this Agreement, consistent standards of quality in
its manufacture of products sold under the Trademarks and any Trademarks in
which the Company has been granted rights pursuant to the Trademark Licenses.

          (i) Patents.  As of the date hereof the Company has no rights in or to
any Patents or Patent Licenses.

          5.  Covenants.  The Company covenants and agrees with the Lender that
from and after the date of this Agreement:

          (a) Further Documentation; Pledge of Instruments.  At any time and
from time to time, upon the written request of the Lender, and at the sole
expense of the Company, the Company will promptly and duly execute and deliver
any and all such further instruments, documents and agreements and take such
further action as the Lender may deem necessary or desirable in order to perfect
and protect any Lien granted or purported to be granted hereby or to enable the
Lender to exercise and enforce its rights and remedies hereunder with respect to
the Collateral.  Without limiting the generality of the foregoing, the Company
will (i) secure all consents and approvals necessary or appropriate for the
assignment to the Lender of any material License or material Contract held by
the Company or in which the Company has any rights,




                                     -10-
<PAGE>
 
(ii) mark conspicuously each item of Chattel Paper and each related Contract and
each of its records pertaining to the Chattel Paper, with a legend, in form and
substance satisfactory to the Lender, indicating that such Chattel Paper or
related Contract is subject to the security interest granted hereby, (iii) if
any Account shall be evidenced by a promissory note or other Instrument
(including, without limitation, any Letter of Credit on which the Company is
named as a beneficiary), deliver and pledge to the Lender hereunder such
certificate, note or other Instrument duly indorsed and accompanied by duly
executed instruments of transfer or assignment, all in form and substance
reasonably satisfactory to the Lender, and (iv) execute and file such financing
or continuation statements, or amendments thereto, and such other instruments or
notices, as may be necessary or desirable, in form and substance reasonably
satisfactory to the Lender, in order to perfect and preserve the security
interest granted or purported to be granted hereby. The Company hereby
authorizes the Lender to file any such financing or continuation statements
without the signature of the Company to the extent permitted by applicable law.
The Company hereby agrees that a carbon, photographic, photostatic or other
reproduction of this Agreement or of a financing statement is sufficient as a
financing statement to the extent permitted by applicable law. If any Inventory
is in the possession or control of any warehouseman or any of the Company's
agents or processors, the Company shall, upon the Lender's reasonable request,
notify such warehouseman, agent or processor of the Lender's security interest
in such Inventory and, upon the Lender's request, instruct them to hold all such
Inventory for the Lender's account and, from and after the occurrence of, and
during the continuance of, an Event of Default, subject to the Lender's
instructions.

          (b) Location of Inventory.  The Company shall keep the Inventory at
the places specified in Schedule 1 hereof, except for Inventory temporarily in
transit between such locations and, so long as no Event of Default has occurred
and is continuing, the Company may designate additional Inventory locations
within the continental United States ("Domestic Locations") by delivering
written notice to the Lender at least thirty (30) days prior to establishing any
such location, provided however, that the Company may, so long as no Event of
Default has occurred and is continuing, designate additional Inventory locations
outside of the continental United States ("Foreign Locations") with prior
written consent of the Lender, which consent may be withheld if the Company is
unable to perfect the Lender's security interest in all Collateral located at
such Foreign Location. Prior to the establishment of a Domestic  Location the
Company shall cause to be made all filings under the UCC necessary or
appropriate to preserve the perfection of the security interests described
herein in the Inventory to be located at such location and to the extent that
such location is owned by any Person other than the Company, will obtain a lien
waiver with respect to such Inventory in form and substance reasonably
satisfactory to the Lender.  Upon the establishment of a Domestic Location,
Schedule 1 hereto shall be deemed amended to add such location thereto without
further action by the Lender or the Company, and the Company hereby authorizes
the Lender to substitute a new Schedule 1 hereto to reflect such additional
location(s).  Prior to the establishment of a Foreign Location in a country
other than the United States, the Company shall cause all requirements under
such countries' law to be satisfied such that the Lender shall have a valid and
enforceable security interest in all Collateral located in such Foreign
Location.



                                     -11-
<PAGE>
 
          (c) Location of Other Collateral.  The Company will keep its principal
place of business and chief executive office and the office where it keeps all
records concerning the Collateral, and the office where it keeps all originals
of any Documents, Instruments or Chattel Paper, at the locations therefor
specified in Schedule 2 unless (i) the Company shall have given the Lender at
least thirty (30) days' prior written notice of the establishment of a new
location (which shall be within the United States) and (ii) the Company shall
have made all filings under the UCC necessary or appropriate and obtained any
Collateral Access Agreements (as determined by the Lender in its reasonable
discretion) to preserve the perfection of Lender's Lien in the Collateral.  The
Company will hold and preserve such records and Documents, Instruments and
Chattel Paper and will permit representatives of the Lender, or any authorized
employee, agent or representative thereof, at any time during customary business
hours and as often as shall be reasonably requested, to inspect and make copies
and abstracts from such records and Documents, Instruments and Chattel Paper.

          (d) Maintenance of Records.  The Company will keep and maintain at the
Company's own cost and expense satisfactory and complete records of the
Collateral in a manner reasonably acceptable to the Lender, including, without
limitation, a record of all payments received and all credits granted with
respect to such Collateral and a record of the Lender's security interest on the
Collateral.  Upon the occurrence and during the continuance of an Event of
Default, the Company shall, for the Lender's further security, deliver and turn
over to the Lender or the Lender's designated representatives at any time upon
request by the Lender or the Lender's designated representative, copies of any
such books and records (including, without limitation, any and all computer
tapes, programs, and source codes relating to the Collateral or any part or
parts thereof).

          (e) Indemnification.  In any suit, proceeding or action brought by the
Lender relating to any Account, Chattel Paper, Contract, General Intangible or
Instrument for any sum owing thereunder, or to enforce any provision of any
Account, Chattel Paper, Contract, General Intangible or Instrument, the Company
will save, indemnify and keep the Lender harmless from and against all expense,
loss or damages suffered by reason of any defense, setoff, counterclaim,
recoupment or reduction of liability whatsoever of the obligor thereunder,
arising out of a breach by the Company of any obligation thereunder or arising
out of any other agreement, indebtedness or liability at any time owing to, or
in favor of, such obligor or its successors from the Company, and all such
obligations of the Company shall be and remain enforceable against and only
against the Company and shall not be enforceable against the Lender.

          (f) Limitations of Liens on Collateral.  The Company will not create,
permit or suffer to exist, and will defend the Collateral against and take such
other action as is necessary to remove, any Lien on the Collateral, and will
defend the right, title and interest of the Lender in and to any of the
Company's rights to the Collateral, including, without limitation, the proceeds
and products thereof, against the claims and demands of all Persons whatsoever,
excluding any Permitted Liens.




                                     -12-
<PAGE>
 
          (g) No Changes in Payments.  The Company will not (i) grant any
extension of the time of payment of any of the Collateral except in the ordinary
course of business or compromise, compound or settle the same for less than the
full amount thereof except in the ordinary course of business, (ii) release,
wholly or partly, any Person liable for the payment thereof except in the
ordinary course of business, or (iii) allow any credit or discount whatsoever
thereon other than trade discounts granted in the ordinary course of business.

          (h) Limitations on Disposition of Assets.  The Company will not sell,
transfer, lease or otherwise dispose of any of the Collateral or contract to do
so, except to the extent permitted under the terms of the Credit Agreement.

          (i) Notice of Liens, etc.  The Company will advise the Lender
promptly, and in reasonable detail, of (i) any material Lien or claim made by or
asserted against any or all of the Collateral, and (ii) the occurrence of any
other event which would have a Material Adverse Effect on the aggregate value of
the Collateral or on the Liens with respect to such Collateral created
hereunder.

          (j) Notice Regarding Governmental Accounts.  The Company shall
promptly comply with, and continue to comply with, the Assignment of Claims Act
of 1940, as amended (31 U.S.C. (S) 3727 et seq.) and any other comparable law or
act enacted by any state or local governmental authority (collectively, the
"Assignment Laws") applicable to all Contracts and all Accounts with respect to
which the United States of America or any department, agency or instrumentality
thereof or any other state or local governmental agency is, respectively, a
party or the Account Debtor (all such Contracts and Accounts hereinafter
collectively referred to as "Government Receivables").  The Company shall
promptly deliver to the Lender evidence of such compliance, which evidence shall
be in form and substance satisfactory to the Lender.  At any time when an Event
of Default has occurred and is continuing, the Company will take any action
required or requested by the Lender to give notice of the Lender's security
interest in such Government Receivables under the provisions of the Assignment
Laws.

          (k) Limitations on Name Change.  The Company will not change its name,
identity or corporate structure in any manner which might make any financing
statement filed hereunder seriously misleading, unless it shall have (i) given
the Lender at least fifteen (15) days' prior written notice thereof, and (ii)
certified to the Lender that all filings reflecting such new name, identity or
structure have been made which are necessary or appropriate to preserve the
perfection of the security interests described herein.

          (l) Limitations on Consignment.  The Company will not at any time
place  Inventory with a value which, in the aggregate, exceeds $100,000, on
consignment with any Person without the Lender's prior written consent, which
consent may not be unreasonably withheld, provided however, that the Lender may
withhold consent if unable to obtain a fully perfected first priority interest
the Collateral to be consigned.  If at any time during the term of




                                     -13-
<PAGE>
 
this Agreement, any Inventory is placed by the Company on consignment with any
Person ("Consignee"), with the prior written consent of the Lender, the Company
shall, prior to the delivery of any such consigned Inventory: (i) provide the
Lender with all consignment agreements and other instruments and documentation
to be used in connection with such consignment, all of which agreements,
instruments and documentation shall be acceptable in form and substance to the
Lender, (ii) prepare, execute and file appropriate financing statements with
respect to any consigned Inventory showing the Consignee as debtor, the Company
as secured party and the Lender as assignee of secured party, (iii) prepare,
execute and file appropriate financing statements with respect to any consigned
Inventory showing the Company as debtor and the Lender as secured party, (iv)
after all financing statements referred to in clauses (ii) and (iii) above shall
have been filed, conduct a search of all filings made against the Consignee in
all jurisdictions in which the Inventory to be consigned is to be located while
on consignment, and deliver to the Lender copies of the results of all such
searches, and (v) notify, in writing, all creditors of the Consignee which are
or may be holders of security interests in the Inventory to be consigned that
the Company expects to deliver certain Inventory to the Consignee, all of which
Inventory shall be described in such notice by item or type.

          (m) Covenants Regarding Patents, Trademarks.  The Company shall notify
the Lender immediately if it knows or has reason to know that any Patent or any
registration relating to any Trademark which is material to the conduct of the
Company's business may become abandoned, canceled or declared invalid, or if any
Trademark or the invention disclosed in any of the Patents is dedicated to the
public domain, or of any material adverse determination in any proceeding in the
United States Patent and Trademark Office or in any United States court
regarding the Company's ownership of any Patent or Trademark which is material
to the conduct of the Company's business, its right to register the same, or to
keep and maintain the same.  If the Company, either itself or through any agent,
employee, licensee or designee, applies for a Patent or files an application for
the registration of any Trademark with the United States Patent and Trademark
Office or in any analogous office or agency in any other country or any
political subdivision thereof, or otherwise obtains rights in any Patent or
Trademark, the Company will promptly inform the Lender, and, upon request of the
Lender, execute and deliver any and all agreements, instruments, documents and
papers as the Lender may request to evidence the Lender's security interest in
such Patent or Trademark and the General Intangibles used in connection
therewith, including, without limitation, in the case of Trademarks, the
goodwill of the Company's business connected with the use thereof or symbolized
thereby.  Consistent with the Company's past business practice, the Company will
take all reasonably necessary actions permitted by applicable law (i) to
prosecute each Patent or Trademark application which is material to the conduct
of the company's business; (ii) to attempt to obtain the broadest Patent or
registration of a Trademark therefrom and (iii) to maintain each Patent and
Trademark registration which is material to the conduct of the Company's
business, including, without limitation, with respect to Patents, payments of
required maintenance fees, and, with respect to Trademarks, filing of
applications for renewal, affidavits of use and affidavits of incontestability.
In the event that the Company fails to take any of such actions, the Lender may
do so in the Company's name or, if an Event of Default has occurred and is
continuing in the Lender's name,




                                     -14-
<PAGE>
 
and all expenses incurred by the Lender in connection therewith shall be paid by
the Company in accordance with Section 9 hereof. Consistent with the Company's
past business practices, the Company shall use its best efforts to detect
infringers of the Patents and Trademarks which are material to its business. In
the event that any of the Patents or Trademarks is infringed or, in the case of
any Trademark, diluted by a third party, the Company shall (i) notify the Lender
promptly after it learns thereof and (ii) unless the Company shall reasonably
determine that such Patent or Trademark is not material to the conduct of the
Company's business, to promptly take appropriate action to enjoin such
infringement or, in the case of any Trademark, dilution and to seek any and all
damages for such infringement or dilution or shall take such other actions
(including entering into licenses or covenants not to sue) as the Company in the
exercise of its business judgment shall reasonably deem appropriate under the
circumstances to protect the Patents or Trademarks. In the event that the
Company fails to take any such actions the Lender may do so in the Company's
name or, if an Event of Default has occurred and is continuing, in the Lender's
name, and all expenses incurred by the Lender in connection therewith shall be
paid by the Company in accordance with Section 9 hereof.

          (n) Covenants Regarding Contracts.  The Company shall use its
reasonable efforts to ensure that all Contracts relating to the Accounts with
respect to which the Account Debtor is the United States of America or any
department, agency or instrumentality thereof, permit the assignment by the
Company to the Lender of such Contract and any Accounts arising thereunder.

          6   Insurance.  (a)  The Company shall at its sole cost and expense
provide and maintain in full force and effect for the benefit of the Lender,
insurance with respect to the Collateral and all parts thereof, as required
under, and on the terms and conditions set forth in, Section 5.04 of the Credit
Agreement, which terms and conditions are hereby incorporated herein by
reference as fully as if fully set forth herein.

          (b) The Company hereby (i) directs all insurers under such policies of
insurance maintained hereunder and under the Credit Agreement to pay all
proceeds payable thereunder directly to the Lender, and (ii) irrevocably makes,
constitutes and appoints the Lender (and all officers, employees or agents
designated by the Lender) as the Company's true and lawful attorney (and agent-
in-fact) for the purpose of making, settling and adjusting claims under such
policies of insurance if the proceeds of such claims are to be applied to the
Obligations pursuant to the last sentence of this Section 6(b), endorsing the
name of the Company on any check, draft, instrument or other item of payment for
the proceeds of such policies of insurance which are to be applied to the
Obligations pursuant to the last sentence of this Section 6(b), and for making
all determinations and decisions with respect to such policies of insurance
which relate to proceeds to be applied to the Obligations.  The Company shall
promptly notify the Lender in writing of any payment it receives of insurance
proceeds in respect of damaged or destroyed Collateral in excess of $150,000.

          (c) If any insurance required to be provided hereunder shall expire,
be withdrawn, become void by breach of any condition thereof by the Company, or
become void or



                                     -15-
<PAGE>
 
questionable by reason of the failure or impairment of the capital of any
insurer, or if for any other reason whatsoever any such insurance shall become
unsatisfactory to the Lender in its reasonable credit judgment, the Company
immediately shall obtain new or additional insurance which shall be satisfactory
to the Lender in its reasonable credit judgment. The Company shall not take out
any separate or additional insurance which is contributing in the event of loss
unless it is properly endorsed and otherwise satisfactory to the Lender in all
respects.

          (d) In the event the Company at any time or times hereafter shall fail
to obtain or maintain any of the policies of insurance required above or to pay
any premium in whole or in part relating thereto, the Lender, without waiving or
releasing any obligations or default by the Company hereunder, may at any time
or times thereafter (but shall not be obligated to) obtain and maintain such
policies of insurance and pay such premium and take any other action with
respect thereto which the Lender deems advisable.  All sums so disbursed by the
Lender, including attorneys' fees, court costs, expenses and other charges
relating thereto, shall be payable, on demand, by the Company to the Lender in
accordance with Section 9 hereof.

          7   Collections.  The Lender may at any time, on or after the
Acceleration Date, open the Company's mail and collect any and all amounts due
from Account Debtors and notify Account Debtors of the Company, parties to the
Contracts of the Company, obligors of Instruments of the Company and obligors in
respect of Chattel Paper of the Company that the Accounts and the right, title
and interest of the Company in and under such Contracts, Instruments and Chattel
Paper have been assigned to the Lender and that payments shall be made directly
to the Lender or to a lockbox designated by the Lender and upon the request of
the Lender, the Company will deposit any and all payments received on account of
any Government Receivables directly to the Lender or to a lockbox designated by
the Lender.  Upon the request of the Lender on or after the Acceleration Date,
the Company will so notify such Account Debtors, parties to such Contracts,
obligors of such Instruments and obligors in respect of such Chattel Paper.  The
Lender may at any time, in its own name or in the name of the Company,
communicate with such Account Debtors, parties to such Contracts, obligors of
such Instruments and obligors in respect of such Chattel Paper to verify with
such Persons to the Lender's satisfaction the existence, amount and terms of any
such Accounts, Contracts, Instruments or Chattel Paper.

          8   Lender's Appointment as Attorney-in-Fact.  On the Closing Date,
the Company shall execute and deliver to the Lender a power of attorney (the
"Power of Attorney") substantially in the form attached hereto as Exhibit A.
The power of attorney granted pursuant to the Power of Attorney is a power
coupled with an interest and shall be irrevocable until the Commitment
Termination Date.  The powers conferred on the Lender under the Power of
Attorney are solely to protect the Lender's interest in the Collateral and shall
not impose any duty upon the Lender to exercise any such powers.  The Lender
agrees that (a) it shall not exercise any power or authority granted  under the
Power of Attorney unless the Lender first declares the Note, including without
limitation, principal, accrued interest and costs of collection and all other
Obligations immediately due and payable, and (b) the Lender shall account for
any moneys




                                     -16-
<PAGE>
 
received by the Lender in respect of any foreclosure on or disposition of the
Collateral pursuant to the Power of Attorney provided that the Lender shall not
have any duty as to any Collateral, and the Lender shall be accountable only for
amounts it actually receives as a result of the exercise of such powers. THE
LENDER OR ITS RESPECTIVE AFFILIATES, OFFICERS, DIRECTORS, EMPLOYEES, AGENTS OR
REPRESENTATIVES SHALL NOT BE RESPONSIBLE TO THE COMPANY FOR ANY ACT OR FAILURE
TO ACT UNDER ANY POWER OF ATTORNEY OR OTHERWISE, EXCEPT IN RESPECT OF DAMAGES TO
THE EXTENT CAUSED BY THEIR OWN GROSS NEGLIGENCE OR WILLFUL MISCONDUCT, NOR FOR
ANY PUNITIVE, EXEMPLARY, INDIRECT OR CONSEQUENTIAL DAMAGES.

          9   Performance by Lender of the Company's Obligations.  If the
Company fails to perform or comply promptly with any of its agreements contained
herein and the Lender, as provided for by the terms of this Agreement, shall
itself perform or comply, or otherwise cause performance or compliance, with
such agreement, the expenses of the Lender incurred in connection with such
performance or compliance, together with interest thereon at the highest rate
then applicable under the Credit Agreement, shall be payable by the Company to
the Lender on demand and shall constitute Obligations secured hereby.

          10  Rights and Remedies Upon Default.  (a)  If an Event of Default
shall occur and be continuing, the Lender may exercise in addition to all other
rights and remedies granted to it in this Agreement and in any other Loan
Document, all rights and remedies of a secured party under the UCC.  Without
limiting the generality of the foregoing, the Company expressly agrees that on
or after the Acceleration Date, without demand of performance or other demand,
advertisement or notice of any kind (except the notice specified below of time
and place of public or private sale) to or upon the Company or any other Person
(all and each of which demands, advertisements and/or notices are hereby
expressly waived to the maximum extent permitted by the UCC and other applicable
law), may forthwith enter upon the premises of the Company where any Collateral
is located through self-help, without judicial process, without first obtaining
a final judgment or giving the Company notice and opportunity for a hearing on
the Lender's claim or the Lender's action, and without paying rent, and collect,
receive, assemble, process, appropriate and realize upon the Collateral, or any
part thereof, and/or may forthwith sell, lease, assign, give an option or
options to purchase, or sell or otherwise dispose of and deliver said Collateral
(or contract to do so), or any part thereof, in one or more parcels at public or
private sale or sales, at any exchange or broker's board or at any of the
Lender's offices or elsewhere at such prices as it may deem best, for cash or on
credit or for future delivery without assumption of any credit risk.  The Lender
shall have the right upon any such public sale or sales, and, to the extent
permitted by applicable law, upon any such private sale or sales, to purchase
the whole or any part of said Collateral so sold, free of any right or equity of
redemption, which equity of redemption the Company hereby releases.  Such sales
may be adjourned and continued from time to time with or without notice.  The
Lender shall have the right to conduct such sales on the Company's premises or
elsewhere and shall have the right to use the Company's premises without charge
for such sales for such time or times as the Lender deems necessary or
advisable.  The Company further agrees, at the Lender's request on or after the
Acceleration Date, to assemble the Collateral and make it




                                     -17-
<PAGE>
 
available to the Lender at places which the Lender shall select, whether at the
Company's premises or elsewhere. Until the Lender is able to effect a sale,
lease, or other disposition of Collateral hereunder, the Lender shall have the
right to use or operate the Collateral, or any part thereof, to the extent that
it deems appropriate for the purpose of preserving Collateral or its value or
for any other purpose deemed appropriate by the Lender. The Lender shall have no
obligation to the Company to maintain or preserve the rights of the Company as
against third parties with respect to the Collateral while the Collateral is in
the possession of the Lender. The Lender may, if it so elects, seek the
appointment of a receiver or keeper to take possession of Collateral and to
enforce any of the Lender's remedies with respect to such appointment without
prior notice or hearing. The Lender shall apply the net proceeds of any such
collection, recovery, receipt, appropriation, realization or sale, as provided
in Section 10(d) hereof, the Company remaining liable for any deficiency
remaining unpaid after such application, and only after so paying over such net
proceeds and after the payment by the Lender of any other amount required by any
provision of law, including Section 9-504(1)(c) of the UCC, need the Lender
account for the surplus, if any, to the Company. To the maximum extent permitted
by applicable law, the Company waives all claims, damages, and demands against
the Lender arising out of the repossession, retention or sale of the Collateral
except such as arise out of the gross negligence or wilful misconduct of the
Lender. The Company agrees that the Lender need not give more than ten (10)
days' notice (which notification shall be deemed given when given in the manner
provided in Section 13 hereof) of the time and place of any public sale or of
the time after which a private sale may take place, and that such notice is
reasonable notification of such matters. The Company shall remain liable for any
deficiency if the proceeds of any sale or disposition of the Collateral are
insufficient to pay all Obligations, the Company also being liable for the
reasonable fees and expenses of any attorneys employed by the Lender to collect
such deficiency.

          (b) The Company also agrees to pay all costs of the Lender, including,
without limitation, the expenses and reasonable attorneys' fees, incurred in
connection with the enforcement of any of its rights and remedies hereunder.

          (c) The Company hereby waives presentment, demand, protest or any
notice (to the maximum extent permitted by applicable law) of any kind in
connection with this Agreement or any Collateral.

          (d) The Proceeds of any sale, disposition or other realization upon
all or any part of the Collateral shall be distributed by the Lender in the
following order of priorities:

              (i)    first, to the Lender in an amount sufficient to pay in full
     the reasonable expenses of the Lender in connection with such sale,
     disposition or other realization, including all expenses, liabilities and
     advances incurred or made by the Lender in connection therewith, including,
     without limitation, reasonable attorney's fees actually incurred by the
     Lender;



                                     -18-
<PAGE>
 
              (ii)   second, to the Lender in an amount equal to the then unpaid
     principal of and accrued interest and prepayment premiums, if any, on the
     Obligations;

              (iii)  third, to the Lender, in an amount equal to any other
     Obligations which are then unpaid; and

              (iv)   finally, upon payment in full of all of the Obligations, to
     pay to the Company, or its representatives or as a court of competent
     jurisdiction otherwise may direct, any surplus then remaining from such
     Proceeds.

          11  Limitation on the Lender's Duties.  The powers conferred on the
Lender hereunder are solely to protect its interest in the Collateral and shall
not impose any duty upon it to exercise any such powers.  Except for exercising
reasonable care in the custody and preservation of Collateral in its possession
or possession of its agents or nominees and the accounting for moneys actually
received by it hereunder, the Lender shall have no duty as to any Collateral or
any income thereon or as to the taking of any necessary steps to preserve rights
against any parties or any other rights pertaining to the Collateral.  The
Lender shall be deemed to have exercised reasonable care in the custody and
preservation of the Collateral in its possession if such Collateral is accorded
treatment substantially equal to that which the Lender accords its own property.

          12  Term of Agreement; Reinstatement; Assignment.  This Agreement and
the Liens granted hereunder shall remain in full force and effect until (x) the
Obligations have been paid and performed in full and the Credit Agreement has
been terminated, (y) the cash collateralization in full of all contingent
obligations and liabilities (other than contingent indemnification obligations
which have not yet been asserted) and (z) the expiration or termination of the
Commitment.  Further, this Agreement and the Liens granted hereunder shall
remain in full force and effect and continue to be effective should any petition
be filed by or against the Company for liquidation or reorganization, should the
Company become insolvent or make an assignment for the benefit of creditors or
should a receiver or trustee be appointed for all or any significant part of the
Company's assets, and shall continue to be effective or be reinstated, as the
case may be, if at any time payment and performance of the Obligations and the
cash collateral for any such contingent obligations and liabilities, or any part
thereof, is, pursuant to applicable law, rescinded or reduced in amount, or must
otherwise be restored or returned by any obligee of the Obligations, whether as
a "voidable preference," "fraudulent conveyance," or otherwise, all as though
such payment or performance had not been made.  In the event that any payment or
performance or any such cash collateral, or any part thereof, is rescinded,
reduced, restored or returned, the Obligations shall be reinstated and deemed
reduced only by such amount paid and not so rescinded, reduced, restored or
returned.

          13  Security Interest Absolute. All rights of the Lender and security
interests hereunder, and all obligations of the Company hereunder, shall be
absolute and unconditional irrespective of:



                                     -19-
<PAGE>
 
              (i)    any lack of validity or enforceability of the Loan
     Documents, the other Security Documents or any other agreement or
     instrument relating thereto;

              (ii)   any change in the time, manner or place of payment of, or
     in any other term of, all or any of the obligations, or any other amendment
     or waiver of or any consent to any departure from the Loan Documents,
     including, without limitation, any increase in the Obligations resulting
     from the extension of additional credit to the Company or otherwise;

              (iii)  any taking, exchange, release or non-perfection of any
     other collateral, or any taking, release or amendment or waiver of or
     consent to departure from any guaranty, for all or any of the Obligations;

              (iv)   any manner of application of collateral, or proceeds
     thereof, to all or any of the Obligations, or any manner of sale or other
     disposition of any collateral for all or any part of the Obligations or any
     other assets of the Company;

              (v)    any change, restructuring or termination of the corporate
     structure or existence of the Company; or

              (vi)   any other circumstance which might otherwise constitute a
     defense available to, or a discharge of, the Company or a third party
     pledgor.

          14  Use and Protection of Patent and Trademark Collateral.
Notwithstanding anything to the contrary contained herein, unless an Event of
Default has occurred and is continuing, the Lender shall from time to time
execute and deliver, upon the written request of the Company, any and all
instruments, certificates or other documents, in the form so requested,
necessary or appropriate in the judgment of the Company to permit the Company to
continue to exploit, license, use, enjoy and protect the Patents and Trademarks.

          15  Amendments; Consents.  No amendment, modification, supplement,
termination, or waiver of any provision of this Agreement, and no consent to any
departure by the Company therefrom, may in any event be effective unless in
writing signed by the Lender, and then only in the specific instance and for the
specific purpose given.
 
          16  Notices.  Except as otherwise provided herein, whenever it is
provided herein that any notice, demand, request, consent, approval, declaration
or other communication shall or may be given to or served upon any of the
parties by any other party, or whenever any of the parties desires to give or
serve upon any other party any other communication with respect to this
Agreement, each such notice, demand, request, consent, approval, declaration or
other communication shall be in writing and shall be delivered in the manner and
to the addresses set forth in Section 9.03 of the Credit Agreement.

          17  Severability; Time of Essence.  Every provision of this Agreement
is intended to be severable.  If any term or provision of this Agreement or any
other document delivered in connection herewith shall be unenforceable in any
respect, the enforceability of the remaining provisions shall not thereby by
affected.  Time is of the essence of this Agreement.

          18  GOVERNING LAW; SUBMISSION TO JURISDICTION.

          (a) THIS AGREEMENT AND ALL OTHER DOCUMENTS CONTEMPLATED HEREBY, AND
THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER SHALL BE CONSTRUED AND

          (b) ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT  MAY
BE BROUGHT IN THE COURTS OF THE STATE OF FLORIDA OR OF THE UNITED STATES FOR THE
SOUTHERN DISTRICT OF FLORIDA, AND, BY EXECUTION AND DELIVERY OF THIS AGREEMENT,
THE COMPANY HEREBY ACCEPTS FOR ITSELF AND IN RESPECT OF ITS PROPERTY, GENERALLY
AND UNCONDITIONALLY, THE JURISDICTION OF THE AFORESAID COURTS.  THE PARTIES
HERETO HEREBY IRREVOCABLY WAIVE TRIAL BY JURY, AND THE COMPANY HEREBY
IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING, WITHOUT LIMITATION, ANY OBJECTION
TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF FORUM NON CONVENIENS, WHICH IT
MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY SUCH ACTION OR PROCEEDING IN
SUCH RESPECTIVE JURISDICTIONS.

          (c) Nothing herein shall affect the right of the Lender to serve
process in any other manner permitted by law or to commence legal proceedings or
otherwise proceed against the Company in any other jurisdiction.

          19  Expenses.  The Company shall pay all reasonable costs, expenses,
taxes and fees incurred (i) by the Lender in connection with the negotiation,
preparation, execution and delivery of this Agreement, the term sheet and
Commitment Letter relating to this Agreement, and all certificates, opinions and
other documents relating to these transactions, including, without limitation,
the disbursements and professional fees of King & Spalding, counsel to the
Lender; (ii) by the Lender in connection with the perfection, registration,
maintenance, administration, custody and preservation of the Collateral,
including, without limitation, with respect to any and all stamp, intangible or
other taxes that may be payable or determined in the future to be payable in
connection with the Loan Documents, this Agreement, the Security Documents, and
all other documents executed or delivered in connection therewith, and relating

the occurrence of any Event of Default or




                                     -21-
<PAGE>
 
acceleration pursuant to Section 8.02 of the Credit Agreement, including,
without limitation, in connection with (a) the negotiation, preparation,
execution and delivery of any waiver, amendment or consent by the Lender
relating to the Loan Documents or the Security Documents, (b) the negotiation of
any restructuring or workout transaction, and the preparation, execution and
delivery of any documents prepared in connection therewith, and (c) enforcement
or foreclosure with respect to the Loan Documents or the Security Documents, in
all such cases such costs, expenses, taxes and fees shall include, without
limitation, the disbursements and reasonable professional fees actually incurred
of counsel to the Lender. To the extent that any such fees and expenses are
subject to value added taxes, such taxes will be paid by the Company. To the
extent reimbursement is sought pursuant to this Section or any other document
executed pursuant hereto, the Lender shall submit to the Company a statement of
expenses to be paid by the Company. Such expenses shall be due and payable
within thirty (30) days of the date of the original statement to the extent that
the Lender is entitled to such reimbursement.

          20  Indemnity. The Company agrees to protect, indemnify and save
harmless the Lender, and all directors, officers, employees and agents of the
Lender, from and against any and all (i) claims, demands and causes of action of
any nature whatsoever brought by any Person not a party to this Agreement and
arising from or related or incident to this Agreement or any other Loan
Document, (ii) costs and expenses incident to the defense of such claims,
demands and causes of action, including, without limitation, reasonable
attorneys' fees, and (iii) liabilities, judgments, settlements, penalties and
assessments arising from such claims, demands and causes of action, provided
such claims, costs and liabilities are not the result of the gross negligence or
willful misconduct of the Lender.  The indemnity contained in this Section shall
survive the termination of this Agreement.

          21  Further Indemnification.  The Company agrees to pay, and to save
the Lender harmless from, any and all liabilities with respect to, or resulting
from any delay in paying, any and all excise, sales or other similar taxes which
may be payable or determined to be payable with respect to any of the Collateral
or in connection with any of the transactions contemplated by this Agreement.

          22  Benefit of the Agreement.  This Agreement shall be binding upon
and inure to the benefit of and be enforceable by the respective successors and
assigns of the parties hereto, provided that the Company may not assign or
transfer any of its interest hereunder without the prior written consent of the
Lender, and no such assignment or transfer of any such obligations shall relieve
the Company of its obligations hereunder unless the Lender shall have consented
to such release in a writing specifically referring to the obligation from which
the Company is to be released.  Without limiting the generality of the
foregoing, the Lender may assign or otherwise transfer all or any portion of its
rights and obligations under this Agreement, to any other Person, and such other
Person shall thereupon become vested with all the benefits in respect thereof
granted to the Lender herein or otherwise, subject, however, to Section 9.08 of
the Credit Agreement (concerning assignments and participations).

such policies; (c) pay or discharge any taxes, liens, security interests, or
other encumbrances levied or placed on or threatened against the Company or its
property; (d) defend any suit, action or proceeding brought against the Company

any time or from time to time, all acts and other things that the Attorney
reasonably deems necessary to perfect, preserve, or realize upon the Company's
property or assets and Attorney's Liens thereon, all as fully and effectively as

there exist an Event of Default, or such would result from the Borrowing, and
(iv) the aggregate outstanding amount of Advances plus Letter of Credit
Obligations, after giving effect to each Borrowing shall not exceed the
Commitment.  At no time shall the number of Borrowings outstanding under this
Article II exceed ten (10); provided that, for the purpose of determining the
number of Borrowings outstanding, all Borrowings consisting of Prime Rate
Advances under the Commitment shall be considered as one Borrowing.  Borrowings
under the Commitment shall be made through Advances by the Lender.  All Advances
by the Lender shall be evidenced by a single Note payable to the Lender in the
form of Exhibit F attached hereto with appropriate insertions.  The Note shall
be dated the date hereof, shall be payable to the order of the Lender in the
principal amount of $20,000,000, shall bear interest as provided for in this
Agreement and shall mature on the Commitment Termination Date or sooner should
the principal and accrued interest thereon be declared immediately due and
payable as provided for hereinafter.

          SECTION 2.02.  Method of Borrowing Under the Commitment.  (a) The
Company shall give the Lender written or telephonic notice (promptly confirmed
in writing) of any requested Borrowing under the Commitment, substantially in
the form of Exhibit G attached hereto (a "Notice of Borrowing"), specifying (i)
the amount of the Borrowing, (ii) the date the proposed Borrowing is to be made
(which shall be a Business Day), (iii) whether the Borrowing will consist of
Prime Rate Advances or LIBOR Advances, and (iv) in the case of a Borrowing
consisting of LIBOR Advances, the duration of the initial Interest Period
Applicable thereto.  Each Notice of Borrowing shall be given to the Lender (x)
in the case of Prime Rate Advances, not later than 11:00 a.m. (Ft. Lauderdale,
Florida time) the same Business Day of such requested Borrowing or (y) in the
case of LIBOR Advances, at least three Business Days before the date such
requested Borrowing is to be made (which shall be a Business Day).  The Lender
shall be entitled to rely on any telephonic Notice of Borrowing which it
believes in good faith to have been given by an Executive Officer of the
Company, and any Advances made by the Lender based on such telephonic notice
shall, when deposited by the Lender to the Company's Account No. 417006231174 at
SunTrust, be Advances for all purposes hereunder.  Lender shall make each
Advance, if it received proper notification as specified above, available in the

          (b)  Whenever the Company desires to convert all or a portion of an
outstanding Borrowing consisting of Prime Rate Advances into one or more
Borrowings consisting of LIBOR Advances, or to continue a Borrowing consisting
of LIBOR Advances for a new Interest Period, it shall give the Lender written
notice or telephonic notice (promptly confirmed in writing) at least three
Business Days before the date of such conversion, specifying each such Borrowing
to be converted into or continued as LIBOR Advances.  Such notice, substantially
in the form of Exhibit H attached hereto (a "Notice of Continuation/Conversion")
shall be given prior to 11:00 a.m. (Ft. Lauderdale, Florida time) on the date
specified.  Each such Notice of Continuation/Conversion shall be irrevocable and
shall specify the aggregate principal amount of the Advances to be converted or
continued, the date of such conversion or continuation and the Interest Period
applicable thereto.  If, upon the expiration of any Interest Period in respect
of any Borrowing, the Company shall have failed to deliver the Notice of
Continuation/Conversion, the Company shall be deemed to have elected to convert
or continue such Borrowing to a Borrowing consisting of Prime Rate Advances.  So
long as any Event of Default shall have occurred and be continuing, no Borrowing
may be converted into or continued as (upon expiration of the current Interest
Period) LIBOR Advances unless the Lender shall have otherwise consented in
writing. No conversion of any Borrowing of LIBOR Advances shall be permitted
except on the last day of the Interest Period in respect thereof.

Guarantor executes and delivers to the Lender a Letter of Credit Application,
provided further that (i) no Letter of Credit shall have an expiration date that
is later than the earlier of (x) one year after the date of issuance thereof or
(y) the Commitment Termination Date (provided that a Letter of Credit may
provide that it is extendible for consecutive one year periods if such period
does not end after the Commitment Termination Date); (ii) the Company shall not
request that the Lender issue any Letter of Credit, if, after giving effect to
such issuance, the sum of the aggregate Letter of Credit Obligations plus the
aggregate outstanding principal amount of the Advances would exceed the
Commitment; and (iii) the Company shall not request that the Lender issue any
Letter of Credit if after giving effect to such issuance, the aggregate Letter
of Credit Obligations would exceed the  Letter of Credit Subfacility.  To the
extent of any conflict between the terms of this Agreement and any Letter of
Credit Application, this Agreement shall control, including, but not limited to
all fees to be paid to Lender under this Agreement.

presented by the beneficiary of such Letter of Credit which would require the
Lender to make payment under the Letter of Credit, provided that the Lender may
require reasonable changes in any such documents and certificates in accordance
with its customary letter of credit practices, and provided further, that no
Letter of Credit shall require payment against a conforming draft to be made
thereunder on the same Business Day that such draft is presented if such
presentation is made after 11:00 AM (Fort Lauderdale, Florida time). In
determining whether to pay any draft under any Letter of Credit, the Lender
shall be responsible only to determine that the documents and certificate
required to be delivered under its Letter of Credit have been delivered, and
that they comply on their face with the requirements of the Letter of Credit.

          (b)  The Lender agrees, subject to the terms and conditions set forth
in this Agreement, to issue for the account of such Account Party a Letter of
Credit in a face amount equal to the face amount requested under paragraph (a)
above, following its receipt of a notice required by Section 2.04(a).

          (c)  As of the Closing Date, each of the Existing Letters of Credit
shall be deemed to have been issued by the Lender in accordance with the terms
hereof.

          SECTION 2.05.  Payment of Amounts drawn under Letters of Credit.

          (a)  In the event of any request for a drawing under any Letter of
Credit by the beneficiary thereof, the Lender shall notify the Company on or
before the date on which the Lender intends to honor such drawing, and the
Company and the Account Party (if other than the Company) jointly and severally
agree to reimburse the Lender on the day on which such drawing is honored in an
amount, in same day funds, equal to the amount of such drawing.

          (b)  Notwithstanding any provision of this Agreement to the contrary,
to the extent that any Letter of Credit or portion thereof remains outstanding
on the Commitment Termination Date, for any reason whatsoever, the Company and
the Guarantors hereby agree that the beneficiary or beneficiaries thereof shall
be deemed to have made a drawing of all available amounts pursuant to such
Letters of Credit on the Commitment Termination Date which amount shall be held
by the Lender, in an interest bearing account, as cash collateral for its
remaining obligations pursuant to such Letters of Credit.

          (c)  As between the Company, any Account Party and the Lender, the
Company and such Account Party assume all risk of the acts and omissions of, or
misuse of, the Letters of Credit issued by the Lender, by the respective
beneficiaries of such Letters of Credit.  In furtherance and not in limitation
of the foregoing, the Lender shall not be responsible (i) for the form,
validity, sufficiency, accuracy, genuineness or legal effect of any document
submitted by any party in connection with the application for and issuance of
such Letters of Credit, even if it should in fact



                                      19
<PAGE>
 
prove to be in any or all respects insufficient, inaccurate, fraudulent or
forged or otherwise invalid; (ii) for the validity or sufficiency of any
instrument transferring or assigning or purporting to transfer or assign any
such Letter of Credit or the rights or benefits thereunder or proceeds thereof
in whole or in part which may prove to be invalid or ineffective for any reason;
(iii) for failure of the beneficiary of any such Letter of Credit to comply
fully with the conditions required in order to draw upon such Letter of Credit;
(iv) for errors, omissions, interruptions or delays in transmission or delivery
of any messages, by mail, cable, telegraph, telex, telecopy or otherwise; (v)
for good faith errors in interpretation of technical terms; (vi) for any loss or
delay in the transmission or otherwise of any document required in order to make
a drawing under any such Letter of Credit or the proceeds thereof; (vii) for the
misapplication by the beneficiary of any such Letter of Credit; and (viii) for
any consequences arising from causes beyond the control of the Lender; provided
however that the Lender shall assume the risk of the acts and omissions of, the
Letters of Credit issued by the Lender which result directly from the Lender's
gross negligence or willful misconduct.

          SECTION 2.06.  Prepayment of Borrowings Under the Commitment.

          (a)  The Company shall have the right to prepay Borrowings under the
Commitment, in whole at any time or in part from time to time, without premium
or penalty (but, in the case of LIBOR Advances, subject to the funding
indemnification provisions of Section 2.16), provided that (i) the Company gives
the Lender prior written notice of such prepayment, specifying the date such
prepayment will occur (which shall be a Business Day), (x) in the case of any
Prime Rate Advance, at least one Business Day in advance of such date or (y) in
the case of any LIBOR Advance during an Interest Period, at least three Business
Days in advance of such date, (ii) each partial prepayment shall be in an amount
of at least $500,000, and (iii) such prepayments include interest accrued, on
the principal amount prepaid, to the prepayment date.

          (b)  The Company, when providing notice of prepayment pursuant to this
Section 2.06, may designate the specific Borrowing or Borrowings which are to be
prepaid.  In the absence of a designation by the Company, the Lender shall make
such designation in its sole discretion.  All voluntary prepayments shall be
applied to the payment of interest before application to principal.

          SECTION 2.07.  Voluntary Reduction of the Commitment.  Upon at least
five (5) Business Days' prior written notice (or telephonic notice promptly
confirmed in writing) to the Lender, which notice shall specify (1) the amount
by which the Commitment is to be terminated and (2) the date such termination is
to occur, the Company shall have the right, without premium or penalty, to
terminate the Commitment, in whole or in part, provided that (a) any partial
termination pursuant to this Section 2.07 shall be in an amount of at least
$1,000,000 and integral multiples of $500,000, (b) the amount of the Commitment
shall not be reduced to an amount less than $10,000,000, and (c) any such
termination shall apply to permanently reduce the Commitment.  If the sum of (i)
the aggregate principal amount of Advances plus (ii) the Letter of Credit
Obligations exceeds the amount of the Commitment as so reduced, the Company
shall immediately repay Borrowings under the Commitment by an amount equal to
such excess, together with accrued but unpaid interest on such excess.



                                      20
<PAGE>
 
          SECTION 2.08.  Termination of the Commitment.  The unpaid principal
balance and all accrued and unpaid interest on the Note will be due and payable
upon the first of the following dates or events to occur:  (i) the Acceleration
Date; or (ii) upon the expiration of the Commitment on the Commitment
Termination Date.

          SECTION 2.09.  Use of Proceeds.  The proceeds of each Borrowing under
the Commitment will be used by the Company solely for general corporate purposes
including working capital and fixed asset capital expenditures.

          SECTION 2.10.  Fees.

          (a)  On the Closing Date, the Company shall pay to SunTrust $50,000
(the "Upfront Fee"), which fee is a one time fee and shall be fully earned and
nonrefundable when paid.

          (b)  The Company shall pay to the Lender, (subject to the last
sentence hereof), a commitment fee (the "Commitment Fee") for the period
commencing on the Closing Date to and including the Commitment Termination Date,
computed at a rate of one-eighth of a percent (0.125%) multiplied by the average
daily unused portion of the Commitment of the Lender, such fee being payable
quarterly in arrears through the last day of each calendar quarter and due not
later than the 5th of the month immediately following the last day of such
calendar quarter, unless such day is not a Business Day, in which case such fee
is payable on the next Business Day following the 5th of such calendar quarter,
commencing on September 30, 1998, and ending on the Commitment Termination Date.
The Commitment Fee is a per annum fee and will be calculated on the basis of a
360-day year for the actual number of days elapsed. For purposes of calculating
the Commitment Fee, outstanding Letter of Credit Obligations shall not be usage
of the Commitment.

          (c)  The Company agrees to pay upon the issuance or negotiation of
each letter of credit, to the Lender, a letter of credit fee equal to the
Applicable LC Fee Percentage as set forth in SunTrust Standard Fee Schedule (the
"Letter of Credit Fee").

          (d)  The Company hereby authorizes the Lender to withdraw an amount
equal to the fees which are due and payable under clauses (a) or (b) above from
any of its accounts with the Lender if not paid on the due date for such fees.
The Lender shall give the Company notice of any such withdrawals, provided,
however, that failure by the Lender to give the Company notice shall not prevent
the Lender from making any such withdrawals under this Section.

          SECTION 2.11.  Interest.

          (a)  Interest Rate. For each Borrowing, subject to the limitations set
forth in Section 2.01, the Company shall be entitled to select between the
following two options to establish the rate of interest at which the unpaid
principal amount of the Note shall accrue:



                                      21
<PAGE>
 
               (i)   Prime Rate Advances - interest shall accrue at the Prime
                     Rate less 0.75%; or

               (ii)  LIBOR Advances - interest shall accrue at LIBOR plus the
                     Applicable Margin.

     Provided that the Company shall not select an interest rate based on LIBOR
for an Interest Period which extends beyond the Expiration Date.

          (b)  Payment of Interest.  Interest shall be payable to the Lender in
arrears as follows:

               (i)   Prime Rate Advances - on the first day of each calendar
                     month.

               (ii)  LIBOR Advances - on the last day of the Interest Period
                     (subject to Section 2.12(c)(iii)), provided however, that
                     if the Interest Period for any LIBOR Advance is 6 months,
                     payment shall be made (x) on the last day of each three
                     month period prior to the expiration of the Interest
                     Period, and if such day is not a Business Day then on the
                     next Business Day, and (y) at the expiration of the
                     Interest Period.

          SECTION 2.12.  Interest Periods.

          (a)  In connection with the making or continuation of, or conversion
into, each Borrowing of LIBOR Advances, the Company shall select an Interest
Period to be applicable to such LIBOR Advance, which Interest Period shall be
either a 1, 2, 3 or 6 month period.

          (b)  In connection with the making of each Prime Rate Advance the
Interest Period shall end on a date not later than the Commitment Termination
Date.

          (c)  Notwithstanding paragraphs (a) or (b) above:

               (i)   The initial Interest Period for any Borrowing of LIBOR
     Advances shall commence on the date of such Borrowing (including the date
     of any conversion from a Borrowing consisting of Prime Rate Advances) and
     each Interest Period occurring thereafter in respect of a continuation of
     such Borrowing shall commence on the day on which the immediately preceding
     Interest Period expires;

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



                                      22
<PAGE>
 
               (iii) Any Interest Period in respect of LIBOR Advances which
     begins on a day for which there is no numerically corresponding day in the
     calendar month at the end of such Interest Period shall, subject to part
     (iv) below, expire on the last Business Day of such calendar month; and

               (iv)  No Interest Period with respect to the Advances shall
     extend beyond the Commitment Termination Date.

          SECTION 2.13.  Extension of Commitment.  No earlier than 180 days but
no later than 120 days prior to the then applicable Commitment Termination Date,
the Company may request that the Commitment Termination Date be extended by the
Lender for an additional two (2) year  period.  The Lender may agree or not
agree to such extension in the exercise of its sole discretion; provided,
however, that the Lender shall inform the Company no later than 90 days prior to
the then applicable Commitment Termination Date of the Lender's decision as to
whether to extend the Commitment Termination Date.  Notwithstanding anything
herein to the contrary, the Commitment Termination Date may only be extended, in
the aggregate, for up to one additional two-year period pursuant to this
Section 2.13. If the Lender agrees, in its sole discretion, to extend the
Commitment Termination Date, then the applicable Commitment Termination Date
shall automatically be so extended two years from such date, upon written notice
thereof being delivered by the Lender, to the Company and completion by the
Company and its Subsidiaries of any conditions to such extension required by the
Lender.

          SECTION 2.14.  Increased Costs.

          (a)  If, by reason of (x) after the date hereof, the introduction of
or any change (including, without limitation, any change by way of imposition or
increase of reserve requirements) in or in the interpretation of any law or
regulation, or (y) the compliance with any guideline or request from any central
bank or other governmental authority or quasi-governmental authority exercising
control over banks or financial institutions generally (whether or not having
the force of law):

          (i)  Lender shall be subject to any tax, duty or other charge with
     respect to its LIBOR Advances or Letter of Credit Obligations or its
     obligation to make LIBOR Advances or issue letters of credit, or the basis
     of taxation of payments to Lender of the principal of or interest on its
     LIBOR Advances or on its obligation to issue Letters of Credit shall have
     changed (except for changes in the tax on the overall net income of, or any
     franchise tax on, the Lender or its Lending Office imposed by the
     jurisdiction in which the  Lender's principal executive office is located);
     or

          (ii) any reserve (including, without limitation, any imposed by the
     Board of Governors of the Federal Reserve System), special deposit or
     similar requirement against assets of, deposits with or for the account of,
     or credit extended by, the Lender's Lending Office shall be imposed or
     deemed applicable or any other condition



                                      23
<PAGE>
 
     affecting its LIBOR Advances or Letter of Credit Obligations or its
     obligation to make LIBOR Advances or issue Letters of Credit shall be
     imposed on the Lender, its Lending Office or the London interbank market;

and as a result thereof there shall be any increase in the cost to the Lender of
agreeing to make or making, funding or maintaining LIBOR Advances (excepts to
the extent already included in the determination of LIBOR for LIBOR Advances) or
Letters of Credit, or there shall be a reduction in the amount received or
receivable by the Lender or its Lending Office, then the Company shall from time
to time, upon written notice from and demand by the Lender on the Company, pay
to the Lender for the account of the Lender within five Business Days after the
date of such notice and demand, additional amounts sufficient to indemnify the
Lender against such increased cost.  A certificate as to the amount of such
increased cost, submitted to the Company by the Lender in good faith and
accompanied by a statement prepared by the Lender describing in reasonable
detail the basis for and calculation of such increased cost, shall, except for
manifest error, be final, conclusive and binding for all purposes.  In the event
that the Company shall pay the increased cost accrued through the date of
payment as required under this Section 2.14(a), plus any funding losses as
described in Section 2.16, then the Company shall have the right to convert the
relevant LIBOR Advance to a Prime Rate Advance and the Lender shall be deemed to
have given its consent thereto, as required hereunder.   The Lender will
promptly notify the Company of any such adoption, change or compliance of which
it has knowledge which will entitle the Lender to compensation pursuant to the
Section, however, the failure to give notice shall not affect the Lender's right
to such compensation.

          (b)  If the Lender shall determine that at any time, because of the
circumstances described in clauses (x) or (y) in Subsection 2.14(a) or any other
circumstances beyond the Lender's reasonable control arising after the date of
this Agreement affecting the Lender or the London interbank market or the United
States secondary certificate of deposit market or the Lender's position in such
markets, LIBOR, as determined by the Lender, will not adequately and fairly
reflect the cost to the Lender of funding its LIBOR Advances, then, and in any
such event:

          (i)   the Lender shall forthwith give notice (by telephone confirmed
     in writing) to the Company;

          (ii)  the Company's right to request and the Lender's obligation to
     make or permit portions of the Advances to remain outstanding past the last
     day of the then current Interest Periods as LIBOR Advances shall be
     immediately suspended; and

          (iii) the Lender shall make an Advance as part of the requested
     Borrowing of LIBOR Advances, as the case may be, as a Prime Rate Advance,
     which such Prime Rate Advance shall, for all other purposes, be considered
     part of such Borrowing.

          SECTION 2.15.  Capital Adequacy. If, after the date of this Agreement,
the Lender shall have determined that the adoption of any applicable law, rule
or regulation regarding capital adequacy, or any change therein, or any change
in the interpretation or administration thereof by any




                                      24
<PAGE>
 
governmental authority, central bank or comparable agency charged with the
interpretation or administration thereof, or compliance by the Lender with any
request or directive regarding capital adequacy not currently in effect or fully
applicable as of the Closing Date (whether or not having the force of law) of
any such authority, central bank or comparable agency, has or would have the
effect of reducing the rate of return on the Lender's capital as a consequence
of its obligations hereunder to a level below that which the Lender could have
achieved but for such adoption, change or compliance (taking into consideration
the Lender's policies with respect to capital adequacy) by an amount deemed by
the Lender in its sole discretion to be material, then, from time to time,
promptly upon demand by the Lender, the Company shall pay the Lender such
additional amount or amounts as will compensate the Lender for such reduction. A
certificate of the Lender claiming compensation under this Section 2.15 and
setting forth the additional amount or amounts to be paid to it hereunder shall
be conclusive absent manifest error. In determining any such amount, the Lender
may use any reasonable averaging and attribution methods. The Lender will
promptly notify the Company of any such adoption, change or compliance of which
it has knowledge which will entitle the Lender to compensation pursuant to this
Section, but the failure to give such notice shall not affect the Lender's right
to such compensation provided the Lender gives such notice within 90 days after
an officer of the Lender having responsibility for the administration of this
Agreement shall have received actual notice of such adoption, change or
compliance.

          SECTION 2.16.  Funding Losses.  The Company shall compensate the
Lender, upon its written request to the Company (which request shall set forth
the basis for requesting such amounts in reasonable detail and which request
shall be made in good faith and, absent manifest error, shall be final,
conclusive and binding upon all of the parties hereto), for all losses, expenses
and liabilities (including, without limitation, any interest paid by the Lender
to lenders of funds borrowed by it to make or carry its LIBOR Advances, in
either case to the extent not recoverable by the Lender in connection with a re-
employment of such funds and including loss of anticipated profits, which the
Lender may sustain): (i) if for any reason (other than a default by the Lender)
a borrowing of, or conversion to or continuation of, LIBOR Advances to the
Company does not occur on the date specified therefor in a Notice of Borrowing
or Notice of Continuation/Conversion (whether or not withdrawn), (ii) if any
repayment (including mandatory prepayments and any conversions) of any LIBOR
Advances by the Company occurs on a date which is not the last day of an
Interest Period applicable thereto, or (iii) if, for any reason, the Company
defaults in its obligation to repay its LIBOR Advances when required by the
terms of this Agreement, provided however, that the Company shall not be
required to pay any penalty or fee for any losses, expenses and liabilities
incurred by the Lender (i) as a result of Lender's determination that the making
or continuance of a LIBOR Advance has become unlawful by compliance by the
Lender in good faith with any applicable law, governmental rule, regulation,
guideline or order as further described in Section 2.22 hereto, or (ii) as a
result of Lender's determination that adequate and fair means do not exist for
ascertaining the applicable interest rate as described in Section 2.21 hereto.

          SECTION 2.17.  Making of Payments.



                                      25
<PAGE>
 
          (a)  The Fees and all payments of principal of, or interest on, the
Note shall be made in immediately available funds free and clear of any
defenses, set-offs, counterclaims or withholdings or deductions for taxes to the
Lender at its principal office in Ft. Lauderdale, Florida, for the Lender's
account.  All such payments shall be made not later than 1:00 p.m. (Ft.
Lauderdale, Florida time) and funds received after that hour shall be deemed to
have been received by the Lender on the next following Business Day.

          (b)  Subject to Subsection 2.12(c)(ii), whenever any payment to be
made hereunder or under any Note shall be stated to be due on a day which is not
a Business Day, the due date thereof shall be extended to the next succeeding
Business Day and, with respect to payments of principal, interest thereon shall
be payable at the applicable rate during such extension.

          SECTION 2.18.  Default Rate of Interest.  On the Acceleration Date, to
the extent permitted by law, all unpaid amounts hereunder shall, on such date
and thereafter, accrue an interest rate of Prime Rate plus an additional two
percent (2.0%) per annum until payment in full.  Interest accruing pursuant to
this Section 2.18 will be due and payable upon demand.

          SECTION 2.19.  Calculation of Interest.  Interest payable on the Note,
including interest payable as provided in Section 2.18, shall be calculated as
follows:

          (a)  Prime Rate Advances - Interest shall be calculated on the basis
of a 365-day year and paid for actual number of days elapsed.

          (b)  LIBOR Advances - Interest shall be calculated on the basis of a
360-day year and  paid for the actual number of days elapsed.

          SECTION 2.20.  Payments Free of Taxes.  All payments made by the
Company under this Agreement and the Note shall be made free and clear of, and
without deduction for, any Tax.  To the extent that the Company is obligated by
Applicable Law to make any deduction or withholding on account of any Tax from
any amount payable to the Lender under this Agreement or the Note, the Company
shall (1) make such deduction or withholding and pay the same to the relevant
governmental authority and (2) pay such additional amount to the Lender as is
necessary to result in the Lender receiving a net after-tax (or after-assessment
or after-charge) amount equal to the amount to which the Lender would have been
entitled under this Agreement or the Note absent such deduction or withholding.

          SECTION 2.21.  Interest Rate Not Ascertainable, etc. In the event that
the Lender, in the case of LIBOR, shall have determined (which determination
shall be made in good faith and, absent manifest error, shall be final,
conclusive and binding upon all parties) that on any date for determining LIBOR
for any Interest Period, by reason of any changes arising after the date of this
Agreement affecting the London interbank market or the Lender's position in such
market, adequate and fair means do not exist for ascertaining the applicable
interest rate on the basis provided for in the definition of LIBOR then, and in
any such event, the Lender shall forthwith give notice (by



                                      26
<PAGE>
 
telephone confirmed in writing) to the Company of such determination and a
summary of the basis for such determination. Until the Lender notifies the
Company that the circumstances giving rise to the suspension described herein no
longer exist, the obligations of the Lender to make or permit portions of the
Advances to remain outstanding past the last day of the then current Interest
Periods as LIBOR Advances shall be suspended, and such affected Advances shall
bear the same interest as Prime Rate Advances.

          SECTION 2.22.  Illegality.

          (a)  In the event that the Lender shall have determined (which
determination shall be made in good faith and, absent manifest error, shall be
final, conclusive and binding upon all parties) at any time that the making or
continuance of any LIBOR Advance has become unlawful by compliance by the Lender
in good faith with any applicable law, governmental rule, regulation, guideline
or order (whether or not having the force of law and whether or not failure to
comply therewith would be unlawful), then, in any such event, the Lender shall
give prompt notice (by telephone confirmed in writing) to the Company of such
determination and a summary of the basis for such determination.

          (b)  Upon the giving of the notice to the Company referred to in
subsection (a) above, (i) the Company's right to request and the Lender's
obligation to make LIBOR Advances shall be immediately suspended, and the Lender
shall make an Advance as part of the requested Borrowing of LIBOR Advances as a
Prime Rate Advance, and (ii) if the affected LIBOR Advance or Advances are then
outstanding, the Company shall immediately, or if permitted by applicable law,
no later than the date permitted thereby, upon at least one Business Day's
written notice to the Lender, convert each such Advance into a Prime Rate
Advance with an Interest Period ending on the date on which the Interest Period
applicable to the affected LIBOR Advances expires.

          (c)  Notwithstanding any other provision contained in this Agreement,
Lender shall not be obligated to issue any Letter of Credit if the issuance of
such Letter of Credit shall have become unlawful or prohibited by compliance by
Lender in good faith with any law, governmental rule, request, order,
injunction, judgment or decree (whether or not having the force of law).

          SECTION 2.23.  Letter of Credit Obligations Absolute.  The obligation
of each Account Party to reimburse the Lender for drawings made under Letters of
Credit issued for the account of the Account Party shall be unconditional and
irrevocable and shall be paid strictly in accordance with the terms of this
Agreement under all circumstances,  including without limitation, the following
circumstances:

          (a)  Any lack of validity or enforceability of any Letter of Credit;

          (b)  The existence of any claim, set-off, defense or other right which
the Company or any Subsidiary or Affiliate of the Company may have at any time
against a beneficiary or any transferee of any Letter of Credit (or any Persons
or entities for whom any such beneficiary or



                                      27
<PAGE>
 
transferee may be acting), or any other Person, whether in connection with this
Agreement, the transactions contemplated herein or any unrelated transaction
(including without limitation any underlying transaction between the Company or
any of its Subsidiaries and Affiliates and the beneficiary for which such Letter
of Credit was procured);

          (c)  Any draft, demand, certificate or any other document presented
under any Letter of Credit proving to be forged, fraudulent or invalid in any
respect or any statement therein being untrue or inaccurate in any respect;

          (d)  Payment by the Lender under any Letter of Credit against
presentation of a demand, draft or certificate or other document which does not
comply with the terms of such Letter of Credit;

          (e)  Any other circumstance or happening whatsoever which is similar
to any of the foregoing; or

          (f)  the fact that a Default or an Event of Default shall have

provided however, that the Account Party shall not be obligated to reimburse the
Lender for drawings made under the Letters of Credit if the payment of such
drawing by the Lender results directly from Lender's gross negligence or wilful
misconduct.

                        REPRESENTATIONS AND WARRANTIES
                        ------------------------------

          The Company and the Subsidiaries represent and warrant as follows:

          SECTION 4.01.  Corporate Status of Company; Status of Subsidiaries.
The Company and each Subsidiary is a corporation, duly organized, validly
existing and in good standing under the laws of the jurisdictions of their
respective incorporation and have the corporate power and authority to own their
respective property and assets and to transact the businesses in which they
respectively are engaged or presently propose to engage and are duly qualified
and in good standing as foreign corporations in all states where failure to be
so qualified and in good standing could have a Materially Adverse Effect.  The
Company and each of its Subsidiaries have the power to own their respective
properties and to carry on their respective businesses as now being conducted.
The Company is adequately capitalized for the purpose of conducting its
business, was not formed solely for the purpose of acting as agent for, or as an
instrumentality of, any Subsidiary.

          SECTION 4.02.  Corporate Power and Authority.  Each of the Company and
the Guarantors has the corporate power and has taken all necessary corporate
action (including, without



                                      32
<PAGE>
 
limitation, any consent of stockholders required by law or by its certificate of
incorporation or bylaws) to authorize it, to execute, deliver and carry out the
terms and provisions of and to incur its obligations under this Agreement, the
Note, any Letter of Credit Applications, the Security Documents and the other
Loan Documents to which it is a party. This Agreement, the Note, the Security
Documents and the other Loan Documents have been duly authorized, executed and
delivered by the Company and the Guarantors party thereto.

          SECTION 4.03.  Compliance with Other Instruments.  The execution,
delivery and performance by the Company and any Guarantors party thereto, as the
case may be, of this Agreement, the Note, any Letter of Credit Applications, the
Security Documents and the other Loan Documents to which it is a party, (a) will
not contravene any provision of Applicable Law, rule, regulation, judgment,
order or ruling, (b) will not conflict with, be inconsistent with, or result in
any breach of any of the terms, covenants, conditions or provisions of, or
constitute a default under, or result in the creation or imposition of any Lien
upon any of the property or assets of the Company or any of its Subsidiaries
pursuant to the terms of any indenture, mortgage, deed to secure debt, deed of
trust, or any other  agreement or instrument to which the Company or any of its
Subsidiaries is a signatory or by which it is bound or to which it may be
subject, (c) will not violate any provision of the certificate of incorporation
(or equivalent thereof) or bylaws (or equivalent thereof) of the Company or any
of its Subsidiaries or other document governing the constitution or conduct of
affairs of any Subsidiary of the Company, (d) will not require any Governmental
Approval that affects the operation of the Company and the Guarantors and which
would have a Materially Adverse Effect were it not obtained, and that has not
been obtained as of the Closing Date and (e) will not result in the creation of
any Lien upon the assets or properties of the Company and its Subsidiaries
except Permitted Liens and those contemplated by the Security Documents.
Neither the Company nor any of its Subsidiaries is a party to, or otherwise
subject to any provision contained in, any instrument evidencing Indebtedness of
the Company or any of its Subsidiaries, any agreement relating thereto or any
other contract or agreement (including its charter) which limits the amount of,
or otherwise imposes restrictions on the incurring of, Indebtedness of the type
to be evidenced by the Note other than the Title XI Financing.

          SECTION 4.04.  Enforceable Obligations. This Agreement, the Note, any
Letter of Credit Application, the Security Documents and the other Loan
Documents constitute the legal, valid and binding obligation of the Company and
the Guarantors party thereto, enforceable in accordance with their terms, except
as the enforceability thereof may be limited by Bankruptcy Law and by general
principles of equity.

          SECTION 4.05.  Governmental Authorizations.  The Company and its
Subsidiaries are in good standing with respect to all governmental
authorizations, consents, approvals, orders, licenses and other actions required
by any governmental or non-governmental authority or Person, except where the
failure to maintain such good standing will not have a Materially Adverse Effect
on the Company and its Subsidiaries.



                                      33
<PAGE>
 
          SECTION 4.06.  Intellectual Property.  Each of the Company and its
Subsidiaries owns or has the right to use all patents, trademarks, service
marks, trade names, copyrights, licenses and other rights, free from burdensome
restrictions, which are material for the operation of its business as presently
conducted.  Nothing has come to the attention of the Company, any of its
Subsidiaries or any of their respective directors and officers to the effect
that (i) any product, process, method, substance, part or other material
presently contemplated to be sold by or employed by the Company or any of its
Subsidiaries in connection with its business may infringe any patent, trademark,
service mark, trade name, copyright, license or other right owned by any other
Person, (ii) there is no pending or threatened claim or litigation against or
affecting the Company or any of its Subsidiaries contesting its right to sell or
use any such product, process, method, substance, part or other material or
(iii) there is not pending or proposed any patent, invention, device,
application or principle or any statute, law, rule, regulation, standard or code
which would prevent, inhibit or render obsolete the production or sale of any
products of, or substantially reduce the projected revenues of, or otherwise
have a Materially Adverse Effect on the Company or any of its Subsidiaries.

          SECTION 4.07.  Outstanding Indebtedness.  Except for (i) Indebtedness
existing on the Closing Date and set forth in Schedule 4.07 and (ii)
Indebtedness permitted by Section 6.01, neither the Company nor any of its
Subsidiaries, on a consolidated basis, has outstanding any Indebtedness.  There
exists no default under the provisions of any instrument evidencing or securing
any Indebtedness of the Company or any of its Subsidiaries or of any agreement
otherwise relating thereto which has had or would reasonably be expected to have
a Materially Adverse Effect.

          SECTION 4.08.  Insurance Coverage.  Each property of the Company or
any of its Subsidiaries is insured for the benefit of the Company or a
Subsidiary of the Company in amounts deemed adequate by the Company's management
in its reasonable business judgment and not materially less than those amounts
customary in the industry in which the Company and its Subsidiaries operate
against risks usually insured against by Persons operating businesses similar to
those of the Company or its Subsidiaries in the localities where such properties
are located, and the Lender has been named loss payee or additional insured, as
its interest may appear, on all such policies.  Attached as Schedule 4.08 hereto
are certificates evidencing such insurance.

          SECTION 4.09.  Title to Properties.  Each of the Company and its
Subsidiaries has (i) good and marketable fee simple title to its respective real
properties (other than real properties it leases from others), including such
real properties reflected in the financial statements referred to in Section
4.14, subject to no Lien of any kind except Permitted Liens, and (ii) good title
to all of its other respective properties and assets (other than properties and
assets which it leases from others), including the other properties and assets
reflected in the financial statements referred to in Section 4.14.  With the
exception of the Company's lease of the Hammond, Louisiana office space, each of
the Company and its Subsidiaries enjoys peaceful and undisturbed possession in
all  leases necessary for the operation of its respective properties and assets,
none of which contains any unusual or burdensome provisions that would adversely
affect or impair the operation of such properties and assets, and all such
leases are valid and subsisting and in full force and effect.  For purposes of
this Section 4.09 the Company's month to month leases on warehouse space in (i)
Dubuque, Iowa, (ii)



                                      34
<PAGE>
 
Gunterville, Alabama, (iii) St. Louis, Missouri and (iv) Avondale, Louisiana,
shall constitute valid and subsisting leases, provided that the Company shall
have other warehouse options in the event they are no longer able to utilize any
one of the warehouses they currently use.

          SECTION 4.10.  No Burdensome Restrictions.  Neither the Company nor
any of its Subsidiaries is a party to any contract or agreement that would
result in any burdensome restrictions that might reasonably be expected to have
a Materially Adverse Effect on the Company or any of its Subsidiaries,
including, but not limited to, any collective bargaining agreements.

          SECTION 4.11.  No Material Violation of Law.  Neither the Company nor
any of its Subsidiaries has any notice of any violation of any law, statute,
order, regulation or judgment entered against it by any court that may
reasonably be expected to have a Materially Adverse Effect.

          SECTION 4.12.  No Default Under Other Agreements.  Neither the Company
nor any of its Subsidiaries is in default under any material agreement to which
it is a party.

          SECTION 4.13.  No Equity Investments.  Neither the Company nor any of
its Subsidiaries possesses investments in any equity or other long-term
investments in any Person, except investments permitted by Section 6.08 or
listed on Schedule 4.13 attached hereto.

          SECTION 4.14.  Financial Statements.  The audited consolidated
financial statements of the Company dated September 30, 1997, and the related
consolidated statements of income (including supporting footnote disclosures),
with the opinion of Coopers & Lybrand, L.L.P., the unaudited consolidated
quarterly financial statements of the Company dated March 31, 1998 (subject to
year end adjustments and supporting footnote disclosures), and the related
consolidated statements of income (including supporting footnote disclosures),
all heretofore furnished to the Lender, are all true and correct in all material
respects and present fairly the consolidated financial condition at the date of
said financial statements and the results of operations for the fiscal period
then ending of the Company.  The Company as of such date did not have any
significant liabilities, contingent or otherwise, including liabilities for
Taxes or any unusual forward or long-term commitments which were not disclosed
by or reserved against in the financial statements referred to above or in the
notes thereto, and at the present time there are no material unrealized or
anticipated losses from any unfavorable commitments of the Company or any of its
Subsidiaries.  All such financial statements have been prepared in accordance
with GAAP applied on a consistent basis throughout the periods involved.  Since
March 31, 1998, there has been no material adverse change in the operations,
business, property or assets of, or in the condition (financial or otherwise)
of, the Company.

          SECTION 4.15.  Litigation.  Except as disclosed on Schedule 4.15
attached hereto, there are no actions, suits, investigations or proceedings
pending or threatened against or affecting the Company or any of its
Subsidiaries or any of their properties or rights by or before any court,
arbitrator or administrative or governmental body that would have a Materially
Adverse Effect on the Company or any of its Subsidiaries.



                                      35
<PAGE>
 
          SECTION 4.16.  Taxes.  Each of the Company and its Subsidiaries has
filed or caused to be filed all declarations, reports and tax returns including,
in the case of the Company and each Subsidiary located in the United States, all
federal and state income tax returns which it is required by law to file, and
has paid all Taxes which are shown as being due and payable on such returns or
on any assessments made against it or any of its properties.  The accruals and
reserves on the books of the Company and its Subsidiaries in respect of Taxes
are adequate in all material respects for all periods.  Neither the Company nor
any of its Subsidiaries has any knowledge of any unpaid adjustment, assessment
or any penalties or interest of significance, or any basis therefor, by any
taxing authority for any period, except those being contested in good faith and
by appropriate proceedings which effectively stay the enforcement of any Lien
and the attachment of a penalty.

          SECTION 4.17.  Margin Regulations.  No part of the proceeds of any of
the Advances will be used for any purpose which violates, or which would be
inconsistent or not in compliance with, the provisions of the applicable Margin
Regulations.

          SECTION 4.18.  ERISA.  Except as disclosed on Schedule 4.18 attached
hereto:

          (a)  Identification of Plans.  (i) Neither the Company nor any ERISA
     Affiliate maintains or contributes to, or has maintained or contributed to,
     any Plan that is an ERISA Plan, and (ii) neither the Company nor any of its
     Subsidiaries maintains or contributes to, or has maintained or contributed
     to, any Plan that is an Executive Arrangement;

          (b)  Compliance.  Each Plan has at all times been maintained, by its
     terms and in operation, in accordance with all Applicable Laws, except such
     noncompliance (when taken as a whole) that will not have a Materially
     Adverse Effect;

          (c)  Liabilities.  Neither the Company nor any of its Subsidiaries is
     currently nor has in the last 6 years been obligated to make contributions
     (directly or indirectly) to a Multiemployer Plan, nor is it currently nor
     will it become subject to any liability (including withdrawal liability),
     tax or penalty whatsoever to any Person whomsoever with respect to any Plan
     including, but not limited to, any tax, penalty or liability arising under
     Title I or Title IV or ERISA or Chapter 43 of the Code, except such
     liabilities (when taken as a whole) as will not have a Materially Adverse
     Effect; and

          (d)  Funding.  The Company and each ERISA Affiliate has made full and
     timely payment of all amounts (i) required to be contributed under the
     terms of each Plan and Applicable Law and (ii) required to be paid as
     expenses of each Plan.  No Plan has an "amount of unfunded benefit
     liabilities" (as defined in Section 4001(a)(18) of ERISA).

          SECTION 4.19.  Compliance With Environmental Laws.

          (a)  The Company and its Subsidiaries are not in violation of, and do
not presently have outstanding any liability under, have not been notified that
they are or may be liable under and



                                      36
<PAGE>
 
do not have knowledge of any liability or potential liability (including any
liability relating to matters set forth in Part A. of Schedule 4.19) except as
set forth in Part A. of Schedule 4.19, under any applicable Environmental Laws
which violation, liability or potential liability could reasonably be expected
to have a Materially Adverse Effect.

          (b)  Except as set forth in Part B. of Schedule 4.19, neither the
Company nor any of its Subsidiaries has received a written request for
information under any Environmental Laws stating or suggesting that the Company
or any of its Subsidiaries has or may have liability thereunder or written
notice that any such Person has been identified as a potentially responsible
party under any Environmental Laws, or any comparable state law, or any public
health or safety or welfare law, nor has any such Person received any written
notification that any Hazardous Substance that it or any of its respective
predecessors in interest has generated, stored, treated, handled, transported,
or disposed of, has been released or is threatened to be released at any site at
which any Person intends to conduct or is conducting a remedial investigation or
other action pursuant to any Environmental Laws.

          (c)  Except as set forth in Part C. of Schedule 4.19, each of the
Company and its Subsidiaries has obtained all  permits, licenses or other
authorizations required for the conduct of their respective operations under all
applicable Environmental and Asbestos Laws and each such authorization is in
full force and effect.

          (d)  Except as set forth in Part D. of Schedule 4.19, each of Company
and its Subsidiaries complies in all material respects with all laws and
regulations relating to equal employment opportunity and employee safety in all
jurisdictions in which it is presently doing business, and the Company will use
its reasonable best efforts to comply, and to cause each of its Subsidiaries to
comply, with all such laws and regulations which may be legally imposed in the
future in jurisdictions in which the Company or any of its Subsidiaries may then
be doing business.

          SECTION 4.20.  Possession of Material Patents, Trademarks, Etc.  Each
of the Company and its Subsidiaries possesses all patents, trademarks, licenses,
and other intellectual property rights that are necessary in any material
respect for the ownership, maintenance and operation of its properties and
assets and they are possessed free from any burdensome restrictions.  To the
Company's knowledge, there are no infringements of such patents, trademarks,
licenses, and other intellectual property rights that could have a Materially
Adverse Effect on the Company or any of its Subsidiaries.

sets forth the name of each Subsidiary of the Company, the jurisdiction of such

Capital Stock of each such Subsidiary have been validly issued and are fully

owned Subsidiary of the Company free of any Lien or claim.

          SECTION 4.22.  Disclosure.  Neither this Agreement, any Loan Document
nor any other document, certificate or statement furnished to the Lender by or
on behalf of the Company or any Guarantor in connection herewith contains any
untrue statement of a material fact or omits to state a material fact necessary
in order to make the statements contained herein and therein not misleading, if,
in either case, such fact is material to an understanding of the financial
condition, business, prospects or property of the Company, or the ability of the
Company to fulfill its obligations under any Loan Documents to which it is a
party.

          SECTION 4.23.  Year 2000 Compliant.  The operating systems for the
Company's and its Subsidiaries' computers and all software applications that run
on such computers are Year 2000 Compliant or will be Year 2000 Compliant no
later than December 31, 1998, except where a failure to be Year 2000 Compliant
will not have a Materially Adverse Effect.  "Year 2000 Compliant" means that
neither the performance nor functionality of the operating systems for the
Company's and its Subsidiaries' computers and all software applications that run
on such computers is affected by dates prior to, during, spanning or after
January 1, 2000, and shall include, but not be limited to (a) accurately
processing (including, but not limited to calculating, comparing and sequencing)
date and time data from, into, and between the years 1999 and 2000 and leap year
calculations, (b) functioning without error, interruption or decreased
performance relating to such date and time data, (c) accurately processing such
date and time data when used in combination with other technology, if the other
technology properly exchanges date and time data, (d) accurate date and time
data century recognition, (e) calculations that accurately use same century and
multi-century formulas and date and time values, (f) date and time data
interface values which reflect the correct century, and (g) processing, storing,
receiving and outputting all date and time data in a format that accurately
indicates the century of the date and time data.

to the operation and management of the Company and its Subsidiaries have been
transferred or otherwise established with the Lender.

          SECTION 4.25.  Solvency.  The Company and Guarantors hereby
acknowledge receipt of fair consideration and reasonably equivalent value for
the incurrence of the obligations hereunder.  Each of the Company and the
Guarantors (i) represents and warrants that, (A) after giving effect to the
incurrence of such obligations and its obligations under any Letter of Credit
applications, and (B) taking into account its rights as Contributing Guarantors,
the present fair salable value of its assets exceeds its liabilities in that it
retains sufficient capital to reasonably anticipate needs and risks of its
ongoing business, and (iii) represents and warrants that, (A) after giving
effect to the incurrence of such obligations and its obligations under any
Letter of Credit applications, and (B) and taking into account its rights as
Contributing Guarantors,  it has not incurred, nor is it obligated for, debts
beyond its ability to pay such debts as they mature, and that the present fair
salable value of its assets is greater than that needed to pay its probable
existing debts as they become due.



                                      38

     Each Guarantor further represents and warrants that because of the
provision of loans, advances and other corporate services by the Company to the
Guarantors, the Guarantors are materially interested in the financial success of
the Company and will materially benefit from the Company's entering into this
Agreement, for which its guaranty is a condition precedent.

          So long as the Note shall remain unpaid or the Lender shall have a
Commitment hereunder, unless the Lender shall otherwise consent in writing:

          SECTION 5.01.  Use of Proceeds.  The proceeds of all Borrowings will

the Board of Governors of the Federal Reserve System) or to extend credit to
others for the purpose of purchasing or carrying any such "margin security" or
"margin stock" or for any other purpose that might deem this transaction as a
"purpose credit" (within the meaning of the regulations of the Board of
Governors of the Federal Reserve System).  If requested by the Lender, the
Company will furnish to the Lender statements in conformity with the
requirements of Federal Reserve Form U-1 referred to in Regulation U.

          SECTION 5.02.  Reporting Covenants.

     (subject to customary year-end audit adjustments), (2) that the covenants
     described in Article VII have been met, and (3) whether a Default or Event
     of Default exists;

          (iii) on a quarterly basis, concurrent with the delivery of the

income statements, statements of cash flows for the Company, and any other
information deemed necessary by the Lender in its discretion.

request.

          SECTION 5.03.  Maintenance of Properties.  The Company shall, and
shall cause each of its Subsidiaries to, maintain, preserve, protect and keep,
or cause to be maintained, preserved, protected and kept, its properties and
every part thereof in good repair, working order and condition, and from time to
time will make or cause to be made all needful  and proper repairs, renewals,
replacements, extensions, additions, betterments, and improvements thereto, so
that the business carried on in connection therewith may be properly and
advantageously conducted at all times other than those which the failure to
maintain would in the aggregate, have no Materially Adverse Effect; provided,
however, that the Company and each Subsidiary shall not be under any obligation
to repair or replace any such properties which have become obsolete or have
become unsuitable or inadequate for the purpose for which they are used.

          SECTION 5.04.  Maintenance of Insurance.  The Company shall, and shall
cause each of its Subsidiaries to, (i) maintain liability and worker's
compensation insurance with financially sound and reputable insurers, and also
maintain adequate insurance on its properties against such hazards and in at

Subsidiaries to, permit any Person designated by the Lender to visit and inspect
any of its properties, corporate books and financial records, to make copies and
take extracts therefrom, and to discuss its




                                      40
<PAGE>
 
accounts, affairs, and finances with the principal officers of the Company and
such Subsidiary during reasonable business hours, all at such times as the
Lender may reasonably request; provided, however, that any time following the
occurrence and continuance of a Default or an Event of Default, no prior notice
to the Company and such Subsidiary shall be required. The Company shall, and
shall cause each of its Subsidiaries to, prepare or cause to be prepared its
interim statements and reports in accordance with GAAP, subject to usual and
customary year end audit adjustments and footnote disclosures.

     (b)  So long as the chief executive office of the Company and its
Subsidiaries remains at 1514 Martens Drive, Hammond, Louisiana, 70401, the
Company shall maintain, at 1717 St. James Place, Suite 550, Houston, Texas,

rights necessary or desirable in the normal conduct of its business, its good
standing in its state of incorporation and its qualification and good standing
as a foreign corporation in all jurisdictions where its ownership of property or
its business activities cause such qualification to be required and the failure
to do so could have a Materially Adverse Effect.

          SECTION 5.07.  Taxes and Claims.

     (a)  The Company shall, and shall cause each of its Subsidiaries to, pay
and discharge (i) all Taxes prior to the date on which penalties attach thereto,
and (ii) all claims (including, without limitation, claims for labor, materials,
supplies or services) (collectively "Other Claims") which, if unpaid, might
become a Lien having a Materially Adverse Effect upon any of its property;
provided, however, that the Company and its Subsidiaries shall not be required
to pay and discharge any such Tax or Other Claim so long as the legality or
amount thereof shall be promptly contested in good faith and by appropriate
proceedings which effectively stay the enforcement of any Lien and the
attachment of a penalty and the Company or such Subsidiary, as the case may be,
shall have set aside appropriate reserves therefor in accordance with GAAP.

     (b)  Anything contained in this Agreement and or in the Note and/or in any
other agreement executed in connection with this Agreement to the contrary
notwithstanding, Lender agrees that Company will not be liable to reimburse

binding on any of them where the failure to comply with such Applicable Law and
Contractual Obligations would reasonably be expected to have a Materially
Adverse Effect.

Subsidiaries to, deliver to the Lender:

          (i)   Promptly after the discovery of the occurrence thereof with
     respect to any Plan, or any trust established thereunder, notice of (A) a
     "reportable event" described in Section 4043 of ERISA and the regulations
     issued from time to time thereunder (other than a "reportable event" not
     subject to the provisions for 30-day notice to the PBGC under such
     regulations), or (B) any other event which could subject the Company or any
     ERISA Affiliate to any material tax, penalty or liability under Title I or
     Title IV of ERISA or Chapter 43 of the Code;

          (ii)  At the same time and in the same manner as such notice must be

amount of liability is $500,000 or more in excess of insurance coverage, and (b)
any disputes which may exist between the Company or any of its Subsidiaries and
any governmental or regulatory body, in which the amount in controversy is
$250,000 or more and which may materially and adversely affect the normal
business operations of the Company or any of its Subsidiaries or any of their
respective properties and assets.

          SECTION 5.11.  Notice of Events of Default.  The Company shall deliver
to the Lender within five (5) days after any Executive Officer obtains any
knowledge of any condition, event or act which creates or causes a Default or an

or such Subsidiary proposes to take with respect thereto.

authority imposed by law applicable to any such Subsidiary, the Company and the
Guarantors shall (1) cause each Person incorporated or otherwise organized in
the United States that hereafter becomes a Material Subsidiary (an "Additional
Guarantor") to become a Guarantor under the Guaranty Agreement and to create a
security interest in favor of the Lender in all of its assets (to the extent
required by the Guarantor Security Agreement), to the Lender upon the creation
of such Additional Guarantor by executing and delivering to the Lender the
Supplemental Documents, and (2) cause each Person incorporated or otherwise
organized in the United States that hereafter becomes a Material Subsidiary to
become a party to the Contribution Agreement by executing a supplement to

          (b)  ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS AGREEMENT OR
ANY OTHER LOAN DOCUMENT MAY BE BROUGHT IN THE COURTS OF THE STATE OF FLORIDA OR
OF THE UNITED STATES FOR THE SOUTHERN DISTRICT OF FLORIDA, AND, BY EXECUTION AND
DELIVERY OF THIS AGREEMENT, THE COMPANY HEREBY ACCEPTS FOR ITSELF AND IN RESPECT
OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, THE JURISDICTION OF THE
AFORESAID COURTS.  THE PARTIES HERETO HEREBY IRREVOCABLY WAIVE TRIAL BY JURY,
AND THE COMPANY HEREBY IRREVOCABLY WAIVES ANY OBJECTION, INCLUDING, WITHOUT
LIMITATION, ANY OBJECTION TO THE LAYING OF VENUE OR BASED ON THE GROUNDS OF
FORUM NON CONVENIENS, WHICH IT MAY NOW OR HEREAFTER HAVE TO THE BRINGING OF ANY
SUCH ACTION OR PROCEEDING IN SUCH RESPECTIVE JURISDICTIONS.

          (c)  Nothing herein shall affect the right of the Lender to serve
process in any other manner permitted by law or to commence legal proceedings or
otherwise proceed against the Company in any other jurisdiction.

          SECTION 9.06.  Expenses.  The Company shall pay all reasonable costs,
expenses, taxes and fees incurred (i) by the Lender in connection with the
negotiation, preparation, execution and delivery of this Agreement, the term
sheet and Commitment Letter relating to this Agreement, and all certificates,
opinions and other documents relating to these transactions, including, without
limitation, the disbursements and professional fees of King & Spalding, counsel
to the Lender and (ii) by the Lender in connection with or after the occurrence
of any Event of Default or acceleration under Section 8.02 of the Credit
Agreement, including, without limitation, in connection with (a) the
negotiation, preparation, execution and delivery of any waiver, amendment or
consent by the Lender relating to the Loan Documents or the Security Documents,
(b) the negotiation of any restructuring or workout transaction, and the
preparation, execution and delivery of any documents prepared in connection
therewith, and (c) enforcement or foreclosure with respect to the Loan Documents
or the Security Documents, in all such cases such costs, expenses, taxes and
fees shall include, without limitation, the disbursements and reasonable
professional fees actually incurred of counsel to any Lender.  To the extent
that any such fees and expenses are subject to value added taxes, such taxes
will be paid by the Company.  To the extent reimbursement is sought pursuant to
this Section or any other document executed pursuant hereto, the Lender shall
submit to the Company a statement of expenses to be paid by the Company.  Such
expenses shall be due and payable within fifteen (15) days of the date of the
original statement to the extent that the Lender is entitled to such
reimbursement.

          SECTION 9.07.  Indemnity.  The Company agrees to protect, indemnify
and save harmless the Lender, and all directors, officers, employees and agents
of the Lender, from and against any and all (i) claims, demands and causes of
action of any nature whatsoever brought by any Person not a party to this
Agreement and arising from or related or incident to this Agreement or any other
Loan Document, (ii) costs and expenses incident to the defense of such claims,
demands and causes of action, including, without limitation, reasonable
attorneys' fees, and (iii) liabilities, judgments, settlements, penalties and
assessments arising from such claims, demands and causes of action,




                                      56
<PAGE>
 
provided such claims, costs and liabilities are not the result of the gross
negligence or willful misconduct of the Lender. The indemnity contained in this
Section shall survive the termination of this Agreement.

          SECTION 9.08.  Benefit of the Agreement.

          (a)  This Agreement shall be binding upon and inure to the benefit of
and be enforceable by the respective successors and assigns of the parties
hereto, provided that the Company may not assign or transfer any of its interest
hereunder without the prior written consent of the Lender, and no such
assignment or transfer of any such obligations shall relieve the Company of its
obligations hereunder unless the Lender shall have consented to such release in
a writing specifically referring to the obligation from which the Company is to
be released.

          (b)  The Lender may make, carry or transfer Advances or Letter of
Credit Obligations at, to or for the account of, any of its branch offices or
the office of an Affiliate of the Lender.  The Lender may assign all or any
portion of its rights in this Agreement and the Note issued to it to a Federal
Reserve Bank; provided that no such assignment shall release the Lender from any
of its obligations hereunder.

          (c)  The Lender may assign or delegate all or a portion of its
interests, rights and obligations under this Agreement and the other Loan
Documents (including all or a portion of any of its Commitment, Letter of Credit
Obligations and the Advances at the time owing to it and the Note held by it) to
another financial or lending institution or entity; provided, however, that (i)
the Company must give its prior written consent to such assignment (which
consent shall not be unreasonably withheld) unless such assignment is to an
Affiliate of the assigning Lender or unless a Default or an Event of Default has
occurred and is continuing, (ii) such assignment or delegation is complete or is
in minimum increments of $1,000,000, and (iii) the parties to each such
assignment shall execute and deliver to the Lender an Assignment Agreement, and,
together with a Note subject to such assignment and, unless such assignment is
to an Affiliate of the Lender, a processing and recordation fee of $3,000.  The
Company shall not be responsible for such processing and recordation fee or any
costs or expenses incurred by the Lender in connection with such assignment.
From and after the effective date specified in each Assignment Agreement, which
effective date shall be at least five (5) Business Days after the execution
thereof, the assignee thereunder (the "Assignee") shall be a party hereto and to
the extent of the interest assigned by such Assignment Agreement, have the
rights and obligations of the Lender under this Agreement.  Within five (5)
Business Days after receipt of the notice and the Assignment Agreement, the
Company, at its own expense, shall execute and deliver to the Lender, in
exchange for the surrendered Note, a new Note to the order of Assignee in a
principal amount equal to the applicable Commitment assumed by it pursuant to
such Assignment Agreement and new Note to the assigning Lender in the amount of
its retained Commitment.  Such new Notes shall be in an aggregate principal
amount equal to the aggregate principal amount of such surrendered Note, shall
be dated the date of the surrendered Note which it replaces, and shall otherwise
be in substantially the form attached hereto.




                                      57

          (d)  The Lender may from time to time sell or otherwise grant
participations in all or a portion of its rights and obligations under this
Agreement and the other Loan Documents (including all or a portion of its
Commitment, Letter of Credit Obligations and the Advances owing to it and the
Note held by it) to another financial or lending institution or entity,
whereupon the holder of any such participation, if the participation agreement
so provides, shall be entitled to all of the rights of the Lender hereunder;
provided, however, that the selling Lender's obligations under this Agreement
shall remain unchanged, (ii) the selling Lender shall remain solely responsible
to the other parties hereto for the performance of such obligations, and (iii)
the Company shall continue to deal solely and directly with the Lender in
connection with the Lender's rights and obligations under this Agreement and the
other Loan Documents, and the Lender shall retain the sole right to enforce the
obligations of the Company relating to the Advances and Letter of Credit
Obligations and to approve any amendment, modification or waiver of any
provisions of this Agreement or the other Loan Documents.  If the Lender sells a
participation hereunder it shall provide prompt written notice to the Company of
the name of such participant.

          SECTION 9.09.  Subordination of Indebtedness.  Any Indebtedness of any
Guarantor now or hereafter owed to the Company is hereby subordinated in right
of payment to the payment by such Guarantor of its Guaranty Obligations such
that if a default in the payment of the Obligations shall have occurred and be
continuing, any such Indebtedness of such Guarantor owed to the Company, if
collected or received by the Company, shall be held in trust by the Company for
the holder of the Obligations and be paid over to the Lender for application of
such Guarantor's Guaranty Obligations.

          SECTION 9.10.  Maximum Interest Rate.  Nothing contained in this
Agreement, or the Note or any Letter of Credit Obligation shall require the
Company to pay interest at a rate exceeding the Maximum Permissible Rate.  If
interest payable to the Lender for any period would exceed the Maximum
Permissible Rate, such interest shall be reduced automatically to the maximum
amount that will not exceed the Maximum Permissible Rate, and interest payable
to the Lender for any subsequent period, to the extent less than the Maximum
Permissible Rate, shall, to that extent, be increased by the aggregate amount of
all such reductions.

          SECTION 9.11.  Entire Agreement.  This Agreement and the other Loan
Documents executed and delivered contemporaneously herewith, together with the
exhibits and schedules attached hereto and thereto, constitute the entire
understanding of the parties with respect to the subject matter hereof, and any
other prior or contemporaneous agreements, whether written or oral, with respect
thereto, including, without limitation, the Commitment Letter, which is
expressly superseded hereby; provided, however, that the indemnities of the
Company in favor of the Lender contained in the Commitment Letter shall survive
the execution and delivery of this Agreement.  The execution of this Agreement
and the other Loan Documents by the Company was not based upon any facts or
materials provided by the Lender, nor was the Company or any Guarantor induced
to execute this Agreement or any other Loan Document by any representation,
statement or analysis made by the Lender.




                                      58

          SECTION 9.12.  Set-Off. Upon and subsequent to the Acceleration Date,
the Lender, and each of its branches and offices, is hereby authorized by the
Company, at any time and from time to time, without notice to the Company (i) to
set off against, and to appropriate and apply to the payment of the Obligations
(in each case whether matured or unmatured) any and all amounts owing by the
Lender, or any such office or branch, to the Company (whether payable in Dollars
or any other currency, whether matured or unmatured, and, in the case of
deposits, whether general or special, time or demand and however evidenced) and
(ii) pending any such action, to the extent necessary, to hold such amounts as
collateral to secure such Obligations and Guaranty Obligations and to return as
unpaid for insufficient funds any and all checks and other items drawn against
any deposits so held as the Lender in its sole discretion may elect.  The Lender
shall give the Company notice of its intention to exercise its rights under this
Section 9.12; provided, however, that failure by the Lender to give the Company
notice shall not prevent the Lender from exercising its rights as provided in
this Section.  The Company, to the fullest extent it may effectively do so under
Applicable Law, agrees that any holder of a participation in any Advance may
exercise rights of set-off and counterclaim and other rights with respect to
such participation as fully as if such holder of a participation were a direct
creditor of the Company in the amount of such participation.

          SECTION 9.13.  Counterparts.  This Agreement may be executed in any
number of counterparts, each of which shall be deemed to be an original and all
of which, taken together, shall constitute one and the same instrument.

          SECTION 9.14.  Replacement Note.  Upon receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of the
Note, and in the case of a loss, theft or destruction, upon delivery of any
indemnity agreement reasonably satisfactory to the Company or, in the case of
any such mutilation, upon surrender and cancellation of the Note, the Company
shall execute and deliver, in lieu thereof, a replacement note identical in form
and substance to the Note and dated as of the date of the Note, and upon such
execution and delivery of the replacement note all references in this Agreement
and in all other Loan Documents to the Note shall be deemed to refer to such
replacement note.

          SECTION 9.15.  Release.  In consideration of the Lender's agreement to
enter into this Agreement and to establish the Commitment hereunder, the Company
hereby (a) releases, acquits and forever discharges the Lender, its respective
agents, employees, officers, directors, servants, representatives, attorneys,
affiliates, successors and assigns (collectively, the "Released Parties") from
any and all liabilities, claims, suits, debts, liens, losses, causes of action,
demands, rights, damages, costs and expenses of any kind, character or nature
whatsoever, known or unknown, fixed or contingent, that the Company may have or
claim to have against the Lender which might arise out of or be connected with
any act of commission or omission of the Lender existing or occurring on or
prior to the date of this Agreement, including, without limitation, any claims,
liabilities or obligations relating to or arising out of or in connection with
the Loan Documents (including, without limitation, arising out of or in
connection with the initiation, negotiation, closing or administration of the
transactions contemplated thereby or related thereto), from the beginning of
time until the execution and delivery of this Agreement (the "Released Claims")
and (b) agrees forever




                                      59

to refrain from commencing, instituting or prosecuting any lawsuit, action or
other proceeding against the Released Parties with respect to any and all
Released Claims.
