                              FINANCIAL STATEMENTS

         The Carbide/Graphite Group, Inc. and Subsidiaries herein are referenced
as the "Company." The Company's current fiscal year ends July 31, 1999.

1.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

INTERIM ACCOUNTING

         The Company's Annual Report on Form 10-K for its fiscal year ended July
31, 1998 includes additional information about the Company, its operations and
its consolidated financial statements, and contains a summary of significant
accounting policies followed by the Company in preparation of its consolidated
financial statements and should be read in conjunction with this quarterly
report on Form 10-Q. These policies were also followed in preparing the
Unaudited Condensed Consolidated Financial Statements included herein. The 1998
year-end consolidated balance sheet data contained herein were derived from
audited financial statements, but does not include all disclosures required by
generally accepted accounting principles.

         In the opinion of management, all adjustments that are of a normal and
recurring nature necessary for a fair statement of the results of operations of
these interim periods have been included. The net income for the nine months
ended April 30, 1999 is not necessarily indicative of the results to be expected
for the full fiscal year. The Management Discussion and Analysis that follows
these notes contains additional information on the results of operations and
financial position of the Company. These comments should be read in conjunction
with these financial statements.

         The weighted-average number of options for common stock outstanding for
the quarter and nine months ended April 30, 1999 were 432,500 and 436,500,
respectively, versus 351,167 and 391,667 for the quarter and nine months ended
April 30, 1998, respectively. Since the Company's results were a net loss from
operations for the quarter and nine months ended April 30, 1998, common
equivalent shares were excluded from the diluted earnings per share computations
for those periods as their effect would have been anti-dilutive.

4.       CONTINGENCIES:

         In May 1997, the Company was served with a subpoena issued by a Grand
Jury empanelled by the United States District Court for the Eastern District of
Pennsylvania. The Company was advised by attorneys for the Department of Justice
(DOJ) that the Grand Jury is investigating price fixing by producers of graphite
products in the United States and abroad during the past five years. The Company
is cooperating with the DOJ in the investigation. The DOJ has granted the
Company and certain former and present senior executives the opportunity to
participate in its Corporate Leniency Program and the Company has entered into
an agreement with the DOJ under which the Company and such executives who
cooperate will not be subject to criminal prosecution with respect to the
investigation if charges are issued by the Grand Jury. Under the agreement, the

                THE CARBIDE/GRAPHITE GROUP, INC. AND SUBSIDIARIES

                         FINANCIAL STATEMENTS--CONTINUED


Company has agreed to use its best efforts to provide for restitution to its
domestic customers for actual damages if any conduct of the Company which
violated the Federal Antitrust Laws in the manufacture and sale of such graphite
products caused damage to such customers.

         Subsequent to the initiation of the DOJ investigation, four civil cases
were filed in the United States District Court for the Eastern District of
Pennsylvania in Philadelphia asserting claims on behalf of a class of purchasers
for violations of the Sherman Act. These cases, which have been consolidated,
name the Company, UCAR International, Inc. (UCAR), SGL Carbon Corporation (SGL
Corp.) and SGL Carbon AG (SGL) as defendants (together, the Named Defendants)
and seek treble damages. On March 30, 1998, a number of purchasers who were
previously included in the purported class of plaintiffs covered by the
consolidated case initiated a separate action in the same District Court which
asserts substantially the same claims and seeks the same relief as the
consolidated case and names the Named Defendants, as well as Showa Denko Carbon,
Inc. (Showa Denko). Thereafter, seven additional groups of purchasers who were
previously included in the purported class of plaintiffs covered by the
consolidated case instituted their own actions against the Named Defendants,
Showa Denko and, in several cases, certain present or former related parties of
UCAR and Showa Denko, asserting substantially the same claims and seeking the
same relief as in the consolidated case. Four such actions were filed in the
United States District Court for the Eastern District of Pennsylvania on April
3, 1998, April 17, 1998, May 14, 1998 and March 31, 1999, respectively. One
action was filed in the United States District Court for the Northern District
of Ohio on April 17, 1998 but has been transferred to the Eastern District of
Pennsylvania for pre-trial proceedings. Another action was filed in the United
States District Court for the Western District of Pennsylvania on June 17, 1998
but has also been transferred to the Eastern District of Pennsylvania for
pre-trial proceedings. The complaints or amended complaints in some of the cases
have also named as defendants other companies including Mitsubishi Corporation,
Tokai Carbon U.S.A., Inc. and related companies. On December 7, 1998, the
Company was served with a complaint filed by Chapparrel Steel Company against
the Named Defendants, Showa Denko and parties related to Showa Denko and UCAR in
state court in Ellis County, Texas alleging violations of various Texas state
antitrust laws and seeking treble damages. Chaparral Steel Company has filed an
amended complaint adding two additional related plaintiffs.

         On February 10, 1999, a U.S. corporation which allegedly made purchases
on behalf of two foreign entities and a group of 22 foreign purchasers which are
based in several foreign countries filed a complaint against the Company, UCAR,
SGL, Tokai Carbon Co., Ltd., Tokai Carbon U.S.A., Inc., Nippon Carbon Co., Ltd.,
SEC Corporation and certain present and former related parties of UCAR in United
States District Court for the Eastern District of Pennsylvania. This complaint
has been amended to add four additional defendants. This case asserts
substantially the same claims and seeks the same relief as the consolidated
case. Other foreign purchasers have also made similar claims against the Company
but have not filed lawsuits.

         The Company understands that defendants UCAR and Showa Denko have
reached settlement agreements with the class action plaintiffs, which have been
approved by the court, and have also settled claims brought by various
individual purchasers. The Company further understands that UCAR, SGL, Robert J.
Koehler and Showa Denko have pleaded guilty to antitrust conspiracy charges
filed by the DOJ and have been ordered to pay fines in connection with those
guilty pleas.

         The Company has also advised the Commission of the European Communities
(the European Commission) that it wishes to invoke its Leniency Notice.
Generally under these guidelines, the European Commission may substantially
reduce fines and other penalties if a company cooperates with the European
Commission and in the judgment of the European Commission provides significant
information. The Company understands that the European Commission will determine
any fines at the completion of its proceedings that may not be concluded for a
year or more.

                         FINANCIAL STATEMENTS--CONTINUED


         On June 18, 1998, a group of Canadian purchasers filed a lawsuit in the
Ontario Court (General Division) claiming a conspiracy and violations of the
Canadian Competition Act. The Canadian lawsuit names the Named Defendants and
Showa Denko, as well as several present or former parents, subsidiaries and/or
affiliates of UCAR, SGL and Showa Denko. The Canadian Competition and Consumer
Law Division (Canadian Division) has initiated an inquiry and the Company is
cooperating fully with the authorities conducting that inquiry pursuant to an
agreement with the Director of Research and Investigation of the Canadian
Division under which the Company and its present and former officers, directors
and employees will not be subject to criminal prosecution.

         During fiscal 1998, the Company recorded a $38 million pre-tax charge
($25 million after expected tax benefits) for potential liabilities resulting
from civil lawsuits, claims, legal costs and other expenses associated with the
pending antitrust matters (the Antitrust Charge). The Company has entered into
settlement agreements with purchasers representing approximately 27% of the
domestic graphite electrode sales that are the subject of the antitrust claims.
These agreements provide for additional payments to such purchasers under
certain conditions. In addition, the Company may settle with various additional
purchasers. The Company understands that defendants UCAR and Showa Denko have
reached settlements with the class action plaintiffs and various individual
purchasers at amounts substantially higher than the levels contemplated in the
Antitrust Charge. Possible future settlements with other purchasers and the
effect of such possible additional payments noted above (along with other
liabilities, costs and expenses resulting from the antitrust matters, including
the European Commission antitrust investigation and future developments) could
result in aggregate costs which could differ materially and adversely from the
Antitrust Charge and could affect the Company's financial condition and its
ability to service its currently planned liquidity needs.

         The Company is also involved in various legal proceedings considered
incidental to the conduct of its business or otherwise not material in the
judgement of management. Management does not believe that its loss exposure
related to these cases is materially greater than amounts provided in the
consolidated balance sheet as of April 30, 1999. As of April 30, 1999, a $0.1
million reserve has been recorded to provide for estimated exposure on claims
for which a loss is deemed probable.


5.       LONG-TERM DEBT:

         During the quarter ended April 30, 1999, the Company entered into an
agreement to amend its five year, $150 million revolving credit facility with a
consortium of banks led by PNC Bank (as amended, the 1997 Revolving Credit
Facility). The amendment, which was effective April 30, 1999, extended the
facility's maturity to December 31, 2003, temporarily increased the maximum
Consolidated Total Indebtedness to EBITDA Ratio and increased the minimum
Consolidated Tangible Net Worth, all as defined in the 1997 Revolving Credit
Facility, as amended. The amendment also provided the bank group additional
collateral (specifically, substantially all of the Company's property, plant and
equipment) under the facility and an increase to the pricing spread on
LIBOR-based interest for various degrees of leverage. As of April 30, 1999, the
interest rate on borrowings outstanding under the 1997 Revolving Credit Facility
was 6.1%.

6.       OTHER ITEMS:

OTHER EXPENSE

         During the nine months ended April 30, 1999, the Company announced
plans to close certain baking and graphitizing operations at its St. Marys,
Pennsylvania plant. Other expense in the nine months ended April 30,

1999 represents an $8.0 million pre-tax charge to provide for the estimated cost
of the facility closure activities. Included in this charge is $5.7 million for
the net write-off of impaired fixed assets and spare parts inventory, $1.4
million for hourly and salary workforce severance costs and $0.9 million in
other closure-related costs.

         Other expense for the quarter and nine months ended April 30, 1998
represents the Antitrust Charge (See Note 4 above).


EXTRAORDINARY LOSS ON THE EARLY EXTINGUISHMENT OF DEBT

         The extraordinary loss on the early extinguishment of debt in the nine
months ended April 30, 1998 represents the premium paid to Senior Note holders
in connection with a tender of substantially all of the Company's 11.5% Senior
Notes and the write off of unamortized deferred financing fees associated with
the Senior Notes tendered and a revolving credit facility replaced in connection
with the tender.


SHARE REPURCHASE PROGRAM

         During the nine months ended April 30, 1999, the Company repurchased
414,200 shares of Common Stock under its share repurchase program at a total
cost of $4.2 million. The Company is authorized to spend an additional $4.3
million under its share repurchase program.

                                   ----------


         Net sales for the quarter ended April 30, 1999 were $58.3 million
versus $72.8 million in the prior year comparable quarter. Graphite electrode
product sales for the quarter ended April 30, 1999 were $44.2 million versus
$52.6 million in the prior year comparable quarter. Calcium carbide product
sales were $14.1 million versus $20.1 million in the prior year comparable
quarter. Net sales for the nine months ended April 30, 1999 were $185.8 million
versus $221.0 million in the prior year comparable period. For the nine months
ended April 30, 1999, graphite electrode product sales decreased 12.1% to $142.3
million, while calcium carbide product sales decreased 26.3% to $43.5 million.

         Within the graphite electrode products segment, graphite electrode net
sales were $31.9 million, a 20.7% decrease resulting from a 14.2% decrease in
electrode shipments and a 7.5% decrease in average electrode prices. Graphite
electrode shipments for the quarter ended April 30, 1999 were 25.8 million
pounds versus 30.1 million



                                       13
<PAGE>   15


pounds in last year's comparable period. Weakness in certain regions of the
global economy had a negative impact on demand for electric arc furnace steel
and, as a result, lower graphite electrode shipments and prices. Lower demand
for electric arc furnace steel and, as a result, graphite electrode demand may
continue for the next several quarters. Domestic and foreign electrode shipments
as a percentage of total electrode shipments for the quarter ended April 30,
1999 were 60.0% and 40.0%, respectively, versus 56.8% and 43.2%, respectively,
in last year's comparable quarter. Average domestic electrode prices during the
quarter ended April 30, 1999 were down 10.3% from last year's comparable quarter
while average foreign net prices were down 4.2% due in part to lower
transactional prices overseas and as a result of a weaker U.S. dollar exchange
rate. The continued strength of the U.S. dollar is expected to continue to have
a negative impact on foreign price realization for the foreseeable future.
Needle coke sales during the quarter ended April 30, 1999 were $6.9 million
versus $6.0 million a year ago. A 54.4% increase in needle coke shipments more
than offset a 26.1% decrease in needle coke prices. Needle coke shipments were
unusually low in last year's third quarter due to the shutdown of Seadrift Coke,
L.P. to install production expansion equipment. The decrease in needle coke
prices was due primarily to the lower demand for graphite electrodes described
above, which in turn has resulted in weakening demand for needle coke
industry-wide. Graphite specialty product sales during the quarter ended April
30, 1999 were $5.4 million versus $6.3 million in the prior year comparable
quarter. The decrease in sales was attributable to lower shipments of granular
graphite.

         For the nine months ended April 30, 1999, graphite electrode sales were
$100.1 million, a 17.6% decrease from the prior year comparable period resulting
from a 12.9% decline in shipments and a 5.2% decline in electrode prices.
Shipments of graphite electrodes for the nine months ended April 30, 1999 were
78.8 million pounds versus 90.5 million pounds in last year's comparable period.
Domestic and foreign electrode shipments as a percentage of total electrode
shipments for the nine months ended April 30, 1999 were 55.9% and 44.1%,
respectively, versus 54.2% and 45.8%, respectively, in the prior year comparable
period. The domestic electrode price decreased 7.5% while the foreign electrode
price decreased 2.5%. Needle coke sales for the nine months ended April 30, 1999
were $25.5 million versus $24.3 million in the prior year comparable period. The
increase in needle coke sales was due to a 29.2% increase in needle coke
shipments, partially offset by an 18.8% decrease in average needle coke prices.
Graphite specialty product sales for the nine months ended April 30, 1999 were
$16.7 million versus $16.1 million in the prior year comparable period, with the
increase resulting from increased sales of bulk graphite.

         In November 1998, one of the Company's graphite customers, Dow Chemical
Company, Inc. (Dow), announced its intention to permanently close its magnesium
production facility in Freeport, Texas. The Company previously supplied Dow with
all of its graphite anode needs under a long-term supply agreement. The
cancellation of the supply agreement accounts for approximately 8 million pounds
of graphite production capacity. In connection with the Company's cost savings
program (discussed below), the Company has eliminated a significant amount of
the costs associated with producing the graphite anodes previously supplied to
Dow. With the weak demand for graphite electrodes, the Company does not believe
that the graphite anodes previously supplied to Dow will be replaced with sales
of electrodes or other graphite products for at least the next several quarters.
The cancellation of this contract contributed to the decline in shipments of
graphite electrodes for the quarter and nine months ended April 30, 1999.

         Within the calcium carbide product segment, pipeline acetylene sales
for the quarter ended April 30, 1999 were $3.6 million versus $7.3 million in
the prior year comparable quarter. The decrease was the result of a significant
decrease in shipments to pipeline acetylene customers. International Specialty
Products (ISP), the Company's largest pipeline acetylene customer, has indicated
that they will replace purchases from the Company with material sourced from
their European operations which may reduce their demand for the Company's
acetylene by as much as 75% of their historical levels. This reduction in demand
may be permanent. Partially offsetting the sales effect of the lower deliveries
to pipeline acetylene customers was an increase in average pipeline acetylene
prices resulting from the fixed cost component of the Company's acetylene supply
contracts. Sales of calcium carbide for metallurgical applications of $5.3
million represented an 11.1% decrease from a year ago, primarily due to lower
shipments. Weakness in domestic steel production by integrated steel producers,



                                       14
<PAGE>   16


coupled with lower prices for magnesium (a substitute product) and selective
promotion of magnesium over calcium carbide by a major distributor, resulted in
the lower sales levels. Also, continued calcium carbide price competition for
this application is expected to result in a further reduction in sales of
calcium carbide for metallurgical applications. Calcium carbide for fuel gas
applications totaled $3.4 million for the quarter ended April 30, 1999, a 33.5%
decrease from a year ago resulting primarily from lower shipments. Net sales of
calcium carbide products are expected to remain at these levels throughout the
balance of fiscal 1999 and, potentially, beyond as a result of weak demand and
increased price competition. All other calcium carbide product sales for the
quarter ended April 30, 1999 totaled $1.8 million, unchanged as compared to a
year ago.

         For the nine months ended April 30, 1999, pipeline acetylene sales were
$13.2 million versus $22.2 million for the comparable period a year ago, a 40.5%
decrease resulting from lower shipments. Sales of calcium carbide for
metallurgical applications were $15.3 million, a 15.3% decrease from a year ago
resulting primarily from lower shipments. Sales of calcium carbide for fuel gas
applications were $10.9 million versus $15.0 million a year ago, with the
decrease resulting from lower shipments and prices. All other calcium carbide
product sales for the nine months ended April 30, 1999 totaled $4.1 million
versus $3.7 million a year ago.

         Gross profit as a percentage of graphite electrode product sales for
the quarter ended April 30, 1999 was 16.0% versus 13.9% in the prior year
comparable quarter. The graphite electrode products gross margin in last year's
third quarter was unusually low due to the Seadrift Coke, L.P. plant shutdown.
Gross profit as a percentage of graphite electrode product sales for the nine
months ended April 30, 1999 was 15.8% versus 18.2% in the prior year comparable
period. The decrease in the gross margin for the nine months ended April 30,
1999 was the result of lower prices of graphite electrodes and needle coke and
the decrease in shipments of graphite electrodes. In addition, depreciation and
amortization was approximately $1.2 million and $3.4 million higher during the
quarter and nine months ended April 30, 1999, respectively. Partially offsetting
the effect of the above was a decline in decant oil costs, which were 17.5% and
20.7% lower during the current quarter and nine-month period, respectively.

         Gross profit as a percentage of calcium carbide product sales for the
quarter ended April 30, 1999 was 11.7% versus 16.8% in the prior year comparable
quarter. Gross profit as a percentage of calcium carbide product sales for the
nine months ended April 30, 1999 was 11.5% versus 16.6% in the prior year
comparable period. The decrease in the gross margin in both periods was the
result of lower sales in the carbide business.

         In response to weak demand for many of the Company's products, the
Company has initiated a comprehensive cost savings program. A component of this
program is the closure of two high-cost graphite production facilities at the
Company's St. Marys, Pennsylvania plant. This cost savings program, coupled with
the commissioning of two major capital projects in the Company's graphite
business in February 1999, will reduce staffing levels by approximately 280
employees Company wide, or approximately 22%, by the end of fiscal 1999. Cost
reduction efforts instituted in response to the lower demand for pipeline
acetylene by ISP will continue to take effect over the remainder of the current
fiscal year. The Company is also attempting to lower raw material,
transportation and other costs to help offset the negative effect of lower
sales.

         Selling, general and administrative expenditures for the quarter ended
April 30, 1999 were $4.2 million versus $3.8 million in the comparable quarter a
year ago. The increase was the result of higher expenses associated with the
Company's variable incentive compensation plans. This increase more than offset
a reduction in general operating expenses during the current quarter which was
the result of the Company's cost savings program. Selling, general and
administrative expenditures for the nine months ended April 30, 1999 were $11.2
million versus $12.0 million in the comparable period a year ago. The decrease
was primarily the result of the Company's cost saving programs.

         During the nine months ended April 30, 1999 and in connection with the
Company-wide cost savings program, the Company announced plans to close certain
baking and graphitizing operations at its St. Marys, PA plant resulting in a 12%
reduction in the Company's graphite electrode production capacity. The Company



                                       15
<PAGE>   17

estimates that it is now capable of producing 110 million pounds of graphite
electrodes per year. Other expense in the nine months ended April 30, 1999
represents an $8.0 million pre-tax charge to provide for the estimated cost of
the facility closure activities. Included in this charge is $5.7 million for the
net write-off of impaired fixed assets and spare parts inventory, $1.4 million
for hourly and salary workforce severance costs and $0.9 million in other
closure-related costs.

         Net interest expense for the quarter ended April 30, 1999 was $1.7
million, including $1.8 million of interest expense associated with the
Company's revolving credit facility and $0.1 million in bank fees, less $0.2
million in capitalized interest. Net interest expense for the quarter ended
April 30, 1998 was $1.2 million, including $1.5 million of interest expense
associated with the revolving credit facility and $0.1 million in bank fees,
less $0.4 million in capitalized interest. Net interest expense for the nine
months ended April 30, 1999 was $4.7 million, including $5.6 million of interest
expense associated with the Company's revolving credit facility and $0.2 million
in bank fees, less $1.1 million in capitalized interest. Net interest expense
for the nine months ended April 30, 1998 was $3.8 million, including $3.4
million of interest expense associated with the revolving credit facility, $1.5
million of interest expense associated with the 11.5% Senior Notes previously
outstanding and $0.4 million in bank fees, less capitalized interest of $1.2
million and interest income of $0.3 million.

         The income tax provision for the quarter and nine months ended April
30, 1999 was recorded based on the Company's projected effective income tax rate
for the fiscal year ending July 31, 1999. The current year effective rate
differs from the federal statutory rate due primarily to state taxes, offset by
benefits derived from the Company's foreign sales corporation.

         As a result of a tender of the Company's Senior Notes and a related
revolving credit facility refinancing, the Company recorded a $6.4 million net
extraordinary loss on the early extinguishment of debt during the nine months
ended April 30, 1998. This extraordinary charge represents the premium paid to
Senior Note holders in connection with the tender and the write off of
unamortized deferred financing fees associated with the Senior Notes tendered
and a revolving credit facility replaced in connection with the tender.


RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

         The Company is required to adopt SFAS #131, "Disclosures about Segments
of an Enterprise and Related Information" (SFAS #131) and SFAS #132, "Employers'
Disclosure about Pensions and Other Postretirement Benefits -- an amendment to
FASB Statements #87, #88 and #106" (SFAS #132) for its fiscal year ending July
31, 1999. SFAS #131 will require the Company to expand its disclosure of
information on its reportable segments. SFAS #132 standardizes the disclosure
requirements for pensions and other postretirement benefits.

         The Company is also required to adopt SFAS #133, "Accounting for
Derivative Instruments and Hedging Activities" (SFAS #133) for its fiscal year
ending July 31, 2001. SFAS #133 establishes accounting and reporting standards
for derivatives and hedging activities. The Company has not yet completed its
evaluation of the financial accounting and reporting impact of SFAS #133.


LIQUIDITY AND CAPITAL RESOURCES

LIQUIDITY

         The Company's liquidity needs are primarily for capital expenditures,
working capital (including potential antitrust settlements) and debt service on
its revolving credit facility. The weakness in certain regions of the global
economy and its impact on demand for the Company's products has resulted in the
deferment of certain discretionary capital projects, including a $40 million
project to install a longitudinal graphitizing facility. The


                                       16
<PAGE>   18

Company believes that its cash flows from operations and availability under its
revolving credit facility should be sufficient to fund all of its currently
planned liquidity needs through at least the expiration of its revolving credit
facility in December 2003, although such liquidity needs may be adversely
impacted by the terms and conditions of any settlements of pending antitrust
claims. In the event these resources are not sufficient to fund the Company's
planned capital expenditures, service its indebtedness and pay any other
obligation including those that may arise from pending legal proceedings and the
resolution of current antitrust matters, the Company may be required to
refinance its revolving credit facility, obtain additional funding or further
delay discretionary capital projects. If the Company were required to refinance
its revolving credit facility or obtain additional funding to satisfy its
liquidity needs, there can be no assurance that sources of funds would be
available in amounts sufficient for the Company to meet its obligations or on
terms favorable to the Company.

         In connection with the tender of substantially all of the Company's
Senior Notes in fiscal 1998, the Company entered into an agreement with a
consortium of banks led by PNC Bank for a $150 million revolving credit facility
with a $15 million sub-limit for letters of credit which will expire in
December, 2003 (as amended, the 1997 Revolving Credit Facility). The 1997
Revolving Credit Facility was amended during the quarter ended April 30, 1999.
Interest under the 1997 Revolving Credit Facility is based on, at the option of
the Company, either PNC Bank's prime rate or a floating LIBOR rate plus a spread
(currently 1.125%) based on a leverage calculation (specifically, the
Consolidated Total Indebtedness to EBITDA Ratio). As of April 30, 1999, the
interest rate on borrowings outstanding under the 1997 Revolving Credit Facility
was 6.1%. Repayment of funds borrowed under the new credit agreement is not
required until the expiration of the facility. The most restrictive covenants
under the 1997 Revolving Credit Facility include a minimum Interest Coverage
Ratio of 3.5 to 1.0 and a minimum Consolidated Tangible Net Worth, all as
defined in the 1997 Revolving Credit Facility agreement. Also, the Company must
not exceed certain levels of leverage (Consolidated Total Indebtedness to
EBITDA, as defined in the agreement) throughout the term of the facility. The
1997 Revolving Credit Facility is collateralized with receivables, inventory and
substantially all of the Company's property, plant and equipment.

         The Company's Board of Directors have authorized the expenditure of up
to $10 million to repurchase the Company's Common Stock. Subject to price and
market considerations and applicable securities laws, such purchases may be made
from time to time in open market, privately negotiated or other transactions. No
time limit was placed on the duration of the repurchase program. The extent and
timing of any repurchases will depend on market conditions and other corporate
considerations, including the Company's liquidity needs. During the nine months
ended April 30, 1999, the Company repurchased 414,200 shares of Common Stock at
a total cost of $4.2 million. The Company has repurchased a total of 467,200
shares of Common Stock under the repurchase program at a total cost of $5.7
million. The Company is authorized to spend an additional $4.3 million under the
repurchase program.


CASH FLOW INFORMATION

         Cash flow provided by operations for the quarter ended April 30, 1999
was $16.9 million. Cash inflows from net income plus non-cash items of $6.4
million were further increased by $10.5 million in net cash inflows from changes
in working capital items, including an $8.0 million net cash inflow from
reductions in accounts receivable and inventory and increases in accounts
payable and accrued expenses. Major operating cash flow items during the quarter
included $1.5 million in settlement payments and legal fees associated with the
pending antitrust investigation, $1.7 million in net interest payments and a
$2.3 million net income tax refund. Cash flow provided by operations for the
nine months ended April 30, 1999 was $21.2 million. Cash inflows from net income
plus non-cash items of $19.5 million, which includes the $5.2 million net charge
for the graphite production facility closure, were further increased by a $1.7
million net cash inflow from changes in working capital items, including a $6.2
million net reduction in accounts receivable. Major cash outlays during the
nine-month period included $6.8 million in settlement payments and legal fees
associated with the pending antitrust investigation, $1.2 million in severance
and other related costs associated with the St. Marys graphite production
facility closure and $4.9 million in net interest payments.



                                       17
<PAGE>   19

         Investing activities for the quarter and nine months ended April 30,
1999 included $4.0 million and $10.0 million, respectively, in capital
expenditures. The Company believes that most of its future investing activity
cash flow requirements will be for capital expenditures. The Company believes
that its future cash flow provided by operations and borrowings under its
revolving credit facility will be adequate to fund its currently planned
investing needs in the future.

         Cash flow used for financing activities for the quarter ended April 30,
1999 was $11.5 million, including a $6.0 million net repayment on the 1997
Revolving Credit Facility. Cash flow used for financing activities for the nine
months ended April 30, 1999 was $9.8 million, including a $3.2 million net
repayment of the 1997 Revolving Credit Facility and a $4.2 million outflow for
funding the Company's share repurchase program.


OTHER ITEMS

ENVIRONMENTAL

         In the process of developing permit applications for facility upgrades
at the Company's Niagara Falls, NY and St. Marys, PA graphite plants, the
Company determined that certain parameters in its air permits do not reflect
current operations. The Company is working to resolve this issue and has advised
the appropriate state environmental authorities. The Company's plan to resolve
this issue at its Niagara Falls, NY plant has been preliminarily approved by the
State of New York environmental authority. This plan will require the Company to
spend approximately $0.3 million in capital improvements to achieve resolution.
With respect to the St. Marys, PA plant, the state has not threatened regulatory
action or any intent to do so, nor has it requested the Company to develop a
proposed plan of action at this time. It is not clear when the state would
require the Company to address this matter. However, the cost of any remedial
action or any fines (if assessed) could be material.


ST. MARYS LABOR CONTRACT

         During the quarter ending July 31, 1999, the Company and the union
representing the hourly workforce at the Company's St. Marys, PA graphite plant
reached a new collective bargaining labor agreement. The new agreement will
expire in June 2001 and was reached on terms deemed satisfactory to the Company.


DIVIDEND OF PREFERRED SHARE PURCHASE RIGHTS

         In May 1999, the Company's Board of Directors declared a dividend
distribution of one Preferred Share Purchase Right on each outstanding share of
Common Stock. The dividend distribution was made on June 1, 1999 payable to
stockholders of record on that date. The Preferred Share Purchase Rights are
designed to ensure that all of the Company's stockholders receive fair and equal
treatment in the event of any proposed takeover of the Company. The Rights are
not intended to prevent a takeover, but should encourage anyone seeking to
acquire the Company to negotiate with the Company's Board of Directors prior to
attempting a takeover. The Preferred Share Purchase Rights plan was filed with
the Securities and Exchange Commission under Form 8-K on June 1, 1999.


YEAR 2000 COMPLIANCE

         The Company is in the process of modifying, upgrading and replacing
certain components of its computer software, operating systems and manufacturing
process control systems to accommodate the Year 2000 changes required for
correct recording of dates in the year 2000 and beyond. The Company has adopted
a


                                       18
<PAGE>   20


comprehensive Year 2000 compliance action plan that includes (i) inventorying
all of its information technology (IT) systems, manufacturing process control
systems and non-IT systems, (ii) assessing these systems and resources for Year
2000 compliance, (iii) remedying and replacing non-compliant systems, (iv)
testing upgraded systems for compliance, and (v) developing contingency plans.
The Company is in the final stages of its action plan and believes that its
significant IT and non-IT systems will be Year 2000 compliant by July 31, 1999.
The Company believes that its current plan will adequately address the Year 2000
issue and the Company does not expect to experience significant operational
problems associated with Year 2000 compliance once its program is complete.

         The Company is also evaluating the Year 2000 compliance programs of its
critical customers, suppliers and service providers in an attempt to determine
the adequacy of their programs in addressing the Year 2000 issue. This
evaluation includes the distribution of questionnaires to such parties and the
development of contingency plans that assume the failure of a third party
critical to the Company's business. The Company believes that the most
reasonably likely worst-case scenario for the Company with respect to the Year
2000 issue is the failure of a critical vendor, including but not limited to a
utility supplier, or the failure of a critical customer, including electric arc
furnace steel producers who use a substantial amount of power in their
production process. A failure by a critical supplier or group of critical
customers could negatively impact sales, profits and cash flows. The Company
believes that the formulation of contingency plans will help mitigate exposure
and losses should such a failure occur. However, because the Company's overall
Year 2000 compliance is contingent upon the readiness of its critical vendors
and customers, there can be no assurance that the Company's Year 2000 compliance
programs will adequately address Year 2000 issues not under its direct control.

Item 3

QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

         There have not been any material changes in the Company's exposures to
market risk during the nine months ended April 30, 1999 that would require an
update to the disclosures provided in the Company's Annual Report on Form 10-K
for the fiscal year ended July 31, 1998.

PART II
Item 1

LEGAL PROCEEDINGS

         In May 1997, the Company was served with a subpoena issued by a Grand
Jury empanelled by the United States District Court for the Eastern District of
Pennsylvania. The Company was advised by attorneys for the Department of Justice
(DOJ) that the Grand Jury is investigating price fixing by producers of graphite
products in the United States and abroad during the past five years. The Company
is cooperating with the DOJ in the investigation. The DOJ has granted the
Company and certain former and present senior executives the opportunity to
participate in its Corporate Leniency Program and the Company has entered into
an agreement with the DOJ under which the Company and such executives who
cooperate will not be subject to criminal prosecution with respect to the
investigation if charges are issued by the Grand Jury. Under the agreement, the
Company has agreed to use its best efforts to provide for restitution to its
domestic customers for actual damages if any conduct of the Company which
violated the Federal Antitrust Laws in the manufacture and sale of such graphite
products caused damage to such customers.

         Subsequent to the initiation of the DOJ investigation, four civil cases
were filed in the United States District Court for the Eastern District of
Pennsylvania in Philadelphia asserting claims on behalf of a class of purchasers
for violations of the Sherman Act. These cases, which have been consolidated,
name the Company, UCAR International, Inc. (UCAR), SGL Carbon Corporation (SGL
Corp.) and SGL Carbon AG (SGL) as defendants (together, the Named Defendants)
and seek treble damages. On March 30, 1998, a number of purchasers who were
previously included in the purported class of plaintiffs covered by the
consolidated case initiated a separate action in the same District Court which
asserts substantially the same claims and seeks the same relief as the
consolidated case and names the Named Defendants, as well as Showa Denko Carbon,
Inc. (Showa Denko). Thereafter, seven additional groups of purchasers who were
previously included in the purported class of plaintiffs covered by the
consolidated case instituted their own actions against the Named Defendants,
Showa Denko and, in several cases, certain present or former related parties of
UCAR and Showa Denko, asserting substantially the same claims and seeking the
same relief as in the consolidated case. Four such actions were filed in the
United States District Court for the Eastern District of Pennsylvania on April
3, 1998, April 17, 1998, May 14, 1998 and March 31, 1999, respectively. One
action was filed in the United States District Court for the Northern District
of Ohio on April 17, 1998 but has been transferred to the Eastern District of
Pennsylvania for pre-trial proceedings. Another action was filed in the United
States District Court for the Western District of Pennsylvania on June 17, 1998
but has also been transferred to the Eastern District of Pennsylvania for
pre-trial proceedings. The complaints or amended complaints in some of the cases
have also named as defendants other companies including Mitsubishi Corporation,
Tokai Carbon U.S.A., Inc. and related companies. On December 7, 1998, the
Company was served with a complaint filed by Chapparrel Steel Company against
the Named Defendants, Showa Denko and parties related to Showa Denko and UCAR in
state court in Ellis County, Texas alleging violations of various Texas state
antitrust laws and seeking treble damages. Chaparral Steel Company has filed an
amended complaint adding two additional related plaintiffs.

         On February 10, 1999, a U.S. corporation which allegedly made purchases
on behalf of two foreign entities and a group of 22 foreign purchasers which are
based in several foreign countries filed a complaint against the Company, UCAR,
SGL, Tokai Carbon Co., Ltd., Tokai Carbon U.S.A., Inc., Nippon Carbon Co., Ltd.,
SEC Corporation and certain present and former related parties of UCAR in United
States District Court for the Eastern District of Pennsylvania. This complaint
has been amended to add four additional defendants. This case asserts
substantially the same claims and seeks the same relief as the consolidated
case. Other foreign purchasers have also made similar claims against the Company
but have not filed lawsuits.

         The Company understands that defendants UCAR and Showa Denko have
reached settlement agreements with the class action plaintiffs, which have been
approved by the court, and have also settled claims brought by various
individual purchasers. The Company further understands that UCAR, SGL, Robert J.
Koehler


                                       21

and Showa Denko have pleaded guilty to antitrust conspiracy charges filed by the
DOJ and have been ordered to pay fines in connection with those guilty pleas.

         The Company has also advised the Commission of the European Communities
(the European Commission) that it wishes to invoke its Leniency Notice.
Generally under these guidelines, the European Commission may substantially
reduce fines and other penalties if a company cooperates with the European
Commission and in the judgment of the European Commission provides significant
information. The Company understands that the European Commission will determine
any fines at the completion of its proceedings that may not be concluded for a
year or more.

         On June 18, 1998, a group of Canadian purchasers filed a lawsuit in the
Ontario Court (General Division) claiming a conspiracy and violations of the
Canadian Competition Act. The Canadian lawsuit names the Named Defendants and
Showa Denko, as well as several present or former parents, subsidiaries and/or
affiliates of UCAR, SGL and Showa Denko. The Canadian Competition and Consumer
Law Division (Canadian Division) has initiated an inquiry and the Company is
cooperating fully with the authorities conducting that inquiry pursuant to an
agreement with the Director of Research and Investigation of the Canadian
Division under which the Company and its present and former officers, directors
and employees will not be subject to criminal prosecution.

         During fiscal 1998, the Company recorded a $38 million pre-tax charge
($25 million after expected tax benefits) for potential liabilities resulting
from civil lawsuits, claims, legal costs and other expenses associated with the
pending antitrust matters (the Antitrust Charge). The Company has entered into
settlement agreements with purchasers representing approximately 27% of the
domestic graphite electrode sales that are the subject of the antitrust claims.
These agreements provide for additional payments to such purchasers under
certain conditions. In addition, the Company may settle with various additional
purchasers. The Company understands that defendants UCAR and Showa Denko have
reached settlements with the class action plaintiffs and various individual
purchasers at amounts substantially higher than the levels contemplated in the
Antitrust Charge. Possible future settlements with other purchasers and the
effect of such possible additional payments noted above (along with other
liabilities, costs and expenses resulting from the antitrust matters, including
the European Commission antitrust investigation and future developments) could
result in aggregate costs which could differ materially and adversely from the
Antitrust Charge and could affect the Company's financial condition and its
ability to service its currently planned liquidity needs.

         The Company is also involved in various legal proceedings considered
incidental to the conduct of its business or otherwise not material in the
judgement of management. Management does not believe that its loss exposure
related to these cases is materially greater than amounts provided in the
consolidated balance sheet as of April 30, 1999. As of April 30, 1999, a $0.1
million reserve has been recorded to provide for estimated exposure on claims
for which a loss is deemed probable.

         (b) item (xi) of the definition of Permitted Liens is amended and
restated in its entirety to read as follows:

                  (xi) "Leases or subleases, including existing operating Leases
         with PNC Leasing Corp. as lessor, not otherwise prohibited by this
         Agreement or other Loan Documents; provided however that, except for

                  (b) Extension of Expiration Date. Commencing in 2000, the
         Borrower may request in a writing delivered to the Agent a one year
         extension of the Expiration Date. The request shall be given not
         earlier than the delivery of the audited financial statements of the
         Borrower and its Subsidiaries for the Fiscal Year just ended nor later

         Year covered by the most recently delivered audited financial
         statements of the Borrower and its Subsidiaries. The Agent shall
         promptly send such request to each of the Lenders. The Lenders at their
         sole and absolute discretion may extend the Expiration Date then in
         effect in one year increments measured from the current Expiration
         Date. No such extension of an Expiration Date shall be effective unless
         the Borrower shall have received a written notice of all Lenders which
         consents to such extension. Such written consent, if given, shall be
         given within 45 days of the receipt by the Agent of the Borrower's
         request for an extension.

         SECTION 1.04 REVISION OF COMMITMENT FEE. Section 2.03 of the Original
Credit Agreement is amended and restated in its entirety to read as follows:

                  2.03. Commitment Fee. Accruing from the Second Amendment
         Effective Date until the Third Amendment Effective Date, the Borrower
         agrees to pay to the Agent for the account of each Lender, as
         consideration for such Lender's Revolving Credit Commitment hereunder,
         a commitment fee (the "Commitment Fee") equal to the Applicable
         Commitment Fee per annum, as set forth in the Second Amendment (all
         computed on the basis of a year of 365 or 366 days, as the case may be,
         and actual days elapsed), on the average daily amount equal to such
         Lender's Revolving Credit Commitment minus such Lender's Ratable Share
         of Total Utilization. Accruing from the Third Amendment Effective Date
         until the Expiration Date, the Borrower agrees to pay to the Agent for
         the account of each Lender, as consideration for such Lender's
         Revolving Credit Commitment hereunder, a Commitment Fee equal to the
         Applicable Commitment Fee per annum, as set forth in the Third
         Amendment, (all computed on the basis of a year of 365 or 366 days, as
         the case may be, and actual days elapsed) on the average daily amount
         equal to such Lender's Revolving Credit Commitment minus such Lender's
         Ratable Share of Total Utilization. All


                                      -3-
<PAGE>   4

         Commitment Fees shall be payable (i) quarterly in arrears beginning
         October 31, 1997 and continuing on the last Business Day of each Fiscal
         Quarter occurring during the term of the Revolving Credit Commitment
         thereafter, (ii) on the Expiration Date and (iii) upon acceleration of
         the Notes.

         On and after the Third Amendment Effective Date, the term "Applicable
         Commitment Fee" shall mean the rate per annum set forth in the chart
         below which corresponds to the range of ratios in which the Borrower's
         Consolidated Total Indebtedness to EBITDA Ratio, as at the end of the
         preceding fiscal quarter, falls:

        -------------------------------------------------------------------
              CONSOLIDATED TOTAL INDEBTEDNESS            APPLICABLE
                      TO EBITDA RATIO                  COMMITMENT FEE
        -------------------------------------------------------------------
        Less than 3.0 to 1.0                                .25%
        -------------------------------------------------------------------
        Equal to or greater than 3.0 to 1.0                .375%
        -------------------------------------------------------------------

         All such adjustments shall be effective as of the date the Borrower's
         quarterly financial statements and Compliance Certificate are required
         to be delivered to the Lenders pursuant to items (i) and (iii) of
         Section 6.02.

         SECTION 1.05 AMENDMENT TO SECTION 2.08(B)(II) OF THE ORIGINAL CREDIT
AGREEMENT. Section 2.08(b)(ii) of the Original Credit Agreement is hereby
amended and restated in its entirety to read as follows:

                  (ii) Euro-Rate Option. Interest under this Interest Rate
         Option shall accrue, for each Euro-Rate Portion of the Revolving Credit
         Loans outstanding, for any Euro-Rate Interest Period selected, at a
         rate per annum equal to the sum of (A) the Euro-Rate plus (B) the
         Applicable Euro-Rate Margin as determined below. The rate of interest
         established pursuant to the preceding sentence of this Section
         2.08(b)(ii) for each Euro-Rate Portion shall be adjusted from time to
         time in accordance with the provisions of Section 2.08(c).

         From the Second Amendment Effective Date until the Third Amendment
         Effective Date the applicable Euro-Rate Margin shall be that set forth
         in the Second Amendment. From the Third Amendment Effective Date, for
         purposes of this Agreement, the term "Applicable Euro-Rate Margin"
         shall mean the rate per annum set forth in the chart below which
         corresponds to the range of ratios in which the Borrower's Consolidated
         Total Indebtedness to EBITDA Ratio as at the end of the preceding
         Fiscal Quarter falls:

         ---------------------------------------------------------------------
            CONSOLIDATED TOTAL INDEBTEDNESS         APPLICABLE EURO-RATE
                 TO EBITDA RATIO                            MARGIN
         ---------------------------------------------------------------------
         Less than 2.5 to 1.0                                1.00%
         ---------------------------------------------------------------------
         Equal to or greater than 2.5 to
         1.0 but less than 3.0 to 1.0                       1.125%

         SECTION 1.06 AMENDMENT TO SECTION 2.17 (B) OF THE ORIGINAL CREDIT
AGREEMENT. Section 2.17 (b) of the Original Credit Agreement is hereby amended
and restated in its entirety to read as follows:

                  (b) The Borrower shall pay (i) to the L/C Issuer for its own
         account a fronting fee equal to 1/8 of 1% per annum (the "L/C Fronting
         Fee") on the aggregate daily (computed at the opening of business and
         on the basis of a year of 365 or 366 days, as the case may be, and
         actual days elapsed) Stated Amount of the outstanding Letters of Credit
         for the period in question, and (ii) to the Agent for the ratable
         account of the Lenders a fee (the "Letter of Credit Fee") equal to the
         Applicable Letter of Credit Fee per annum, as determined below, on the
         aggregate daily (computed at the opening of business and on the basis
         of a year of 365 or 366 days, as the case may be, and actual days
         elapsed) Stated Amount of the outstanding Letters of Credit for the
         period in question. The Letter of Credit Fee and the L/C Fronting Fee
         shall be payable (i) quarterly in arrears on the last Business Day of
         each Fiscal Quarter occurring during the term of this Agreement
         thereafter, (ii) on the Expiration Date or (iii) upon acceleration of
         the Notes. Any issuance of an amendment to extend the stated expiration
         date of a Letter of Credit or an amendment to increase the Stated
         Amount of a Letter of Credit shall be treated as an issuance of a new
         Letter of Credit for purposes of calculation of the Letter of Credit
         Fee and the L/C Fronting Fee due and payable hereunder. The Borrower
         shall also pay to the L/C Issuer the L/C Issuer's customary
         documentation fees payable with respect to the Letters of Credit as the
         L/C Issuer may generally charge from time to time. After the occurrence
         of an Event of Default (which continues after the expiration of any
         cure period applicable thereto) and during the continuation thereof,
         the rate at which the Letter of Credit Fee is calculated shall be
         increased by two hundred (200) basis points (2%) above the pre-default
         rate; the increase to be payable monthly during the continuation of the
         Event of Default.

         From the Second Amendment Effective Date until the Third Amendment
         Effective Date the Applicable Letter of Credit Fee shall be that set
         forth in the Second Amendment. From the Third Amendment Effective Date,
         for purposes of this Agreement, the term "Applicable Letter of Credit
         Fee" shall mean the rate per annum set forth in the chart below which
         corresponds to the range of ratios

                  without the prior written consent of the Lenders.

                           (ii) Notwithstanding anything to the contrary
                  contained herein, any Lender (a "GRANTING LENDER") may grant
                  to a special purpose funding vehicle (an "SPC") the option to
                  fund all or any part of any Loan that such Granting Lender
                  would otherwise be obligated to fund pursuant to this
                  Agreement; provided that (A) nothing herein shall constitute a
                  commitment by any SPC to fund any Loan, and (B) if an SPC
                  elects not to exercise such option or otherwise fails to fund
                  all or any part of


                                      -10-
<PAGE>   11

                  such Loan, the Granting Lender shall be obligated to fund such
                  Loan pursuant to the terms hereof. Further, (A) all credit
                  decisions relating to any such funding by the SPC shall be
                  made by the Granting Lender for and on behalf of the SPC, (B)
                  the SPC shall have no voting rights under any of the Loan
                  Documents and (C) except for the payment of principal,
                  interest and fees, if any, the Agent shall be entitled to
                  treat the Granting Lender as the Lender for all purposes
                  hereunder as if the SPC had made no funding of any Loan. The
                  funding of a Loan by an SPC hereunder shall utilize the
                  Revolving Credit Commitment of the Granting Lender to the same
                  extent, and as if, such Loan were funded by such Granting
                  Lender. Each Party hereto hereby agrees that no SPC shall be
                  liable for any indemnity or payment under this Agreement for
                  which a Lender would otherwise be liable for so long as, and
                  to the extent, the Granting Lender provides such indemnity or
                  makes such payment. Notwithstanding anything to the contrary
                  contained in this Agreement, any SPC may disclose on a
                  confidential basis any non-public information relating to its
                  funding of Loans to any rating agency, commercial paper dealer
                  or provider of any surety or guarantee to such SPC. This
                  Section may not be amended without the prior written consent
                  of each Granting Lender, all or any part of whose Loan is
                  being funded by an SPC at the time of such amendment.

         SECTION 1.17 MODIFICATION OF REVOLVING CREDIT NOTES. Each Revolving
Credit Note is hereby amended by inserting after the date September 30, 2002, in
the second paragraph of each such Revolving Credit Note, the phrase "or such
later date as determined by the Lenders in accordance with Section 2.01(b) of
the Agreement."

         SECTION 1.18 NO OTHER AMENDMENTS. The amendments to the Original Credit
Agreement set forth in Sections 1.01 through 1.17 above do not either implicitly
or explicitly alter, waive or amend, except as expressly provided in this Third
Amendment, the provisions of the Original Credit Agreement. The amendments set
forth in Sections 1.01 through 1.17 hereof do not waive, now or in the future,
compliance with any other covenant, term or condition to be performed or
complied with nor do they impair any rights or remedies of the Lenders and the
Agents under the Original Credit Agreement with respect to any such violation.

                                    that, upon the reasonable request of the
                                    Agent, the Debtor shall deliver, or cause to
                                    be delivered, a complete and accurate list,
                                    in all material respects, of Inventory as of
                                    the last day of such fiscal quarter,
                                    including in each case such information as
                                    the Agent may reasonably require. The Debtor
                                    shall conduct a physical inventory of the
                                    Inventory at least once each year, and shall
                                    make a written report to the Agent of such
                                    physical inventory within forty-five (45)
                                    days after the taking of such physical
                                    count. The Debtor shall promptly furnish to
                                    the Agent all such additional information
                                    and documents (including, without
                                    limitation, invoices, purchase orders,
                                    shipping and receipt records and inventory
                                    logs) as the Agent may from time to time
                                    reasonably request.

                           (f)      The Debtor will not invoice any Person
                                    responsible for the payment or other
                                    performance of any Account (each, an
                                    "Account Debtor", and collectively the
                                    "Account Debtors") or maintain the records
                                    of the Debtor relating to the Assigned
                                    Collateral in any name other than its proper
                                    corporate name, except such new name(s) as
                                    it may establish in accordance with
                                    subparagraph (g) below.

                           (g)      If the Debtor desires to establish a new
                                    location for its principal executive office
                                    and place of business or to establish a new
                                    name or names in which it may invoice
                                    Account Debtors or maintain records
                                    concerning the Assigned Collateral, then the
                                    Debtor shall first, with respect to each
                                    such new location or name:

                                    (1)     give the Agent prior written notice
                                            of its intention to do so and
                                            provide the Agent with such
                                            information in connection therewith
                                            as the Agent may reasonably request;
                                            and

                                    (2)     take such action, reasonably
                                            satisfactory to the Agent, as may be
                                            necessary to maintain at all times
                                            the perfection and priority of the
                                            liens and security interests granted
                                            to the Agent (for the benefit of the
                                            Agent, the Lenders and the L/C
                                            Issuer) under this Security

                           (h)      The Agent may at any time, with notice to
                                    the Debtor, verify with any Account Debtors
                                    or any other Person, the status of any
                                    Account. The Debtor from time to time will
                                    execute and deliver such instruments and
                                    take all such action as the Agent may
                                    reasonably request in order to effectuate
                                    the purposes of this subparagraph (h).

                           (i)      The Debtor shall promptly notify the Agent
                                    of all disputes (including without
                                    limitation any rejection or revocation of
                                    acceptance of goods) between the Debtor and
                                    any Account Debtor concerning any amount in
                                    excess of $1,000,000 due and owing under any
                                    single Account or in excess of $2,000,000 in
                                    the aggregate due and owing under all
                                    Accounts from all Account Debtors, including
                                    the reason for the disputes, all claims
                                    related thereto and the amounts in
                                    controversy. The Debtor will promptly notify
                                    the Agent if the Debtor has notice or
                                    knowledge of claims or materially adverse
                                    changes which will or which would be
                                    reasonably likely to affect the ultimate
                                    collectibility of any or all of the Accounts
                                    of an Account Debtor then obligated to pay
                                    the Debtor in excess of $1,000,000 in the
                                    aggregate. The Debtor shall not accept any
                                    return of Inventory the sale of which
                                    generated an Account on which the Account
                                    Debtor is then obligated to pay an amount in
                                    excess of $1,000,000, and shall not accept
                                    any returns of Inventory the sale of which
                                    together with all other sales of Inventory
                                    generated Accounts on which all Account
                                    Debtors are obligated to pay an amount in
                                    excess of $2,000,000 in the aggregate,
                                    without the prior written consent of the
                                    Agent.

                           (j)      The Debtor will not remove or permit the
                                    removal of any of the Assigned Collateral
                                    consisting of Equipment and Fixtures from
                                    the locations shown on Schedule 2, and will
                                    not locate any Equipment or Fixtures at
                                    locations other than the locations shown on
                                    Schedule 2, except for asset dispositions
                                    which are specifically permitted pursuant to
                                    Section 7.05 of the Credit Agreement without
                                    the prior written consent of the Agent,
                                    which consent shall not be unreasonably
                                    withheld. The Debtor shall provide to the
                                    Secured Party promptly upon request adequate
                                    evidence that any removal or location of any
                                    such Assigned Collateral was permitted by
                                    such Section 7.05, and shall ensure that any
                                    replacement Equipment, Goods and Fixtures
                                    are free and clear of all Liens, except for
                                    Permitted Liens.

                           (k)      If the Debtor fails to comply with the
                                    provisions of Section 6.04 of the Credit
                                    Agreement, the Agent may (but shall not be
                                    obligated to) pay any taxes, levies or
                                    impositions relative to the Assigned
                                    Collateral, for the account of the Debtor
                                    and add the amounts thereof to the Secured
                                    Obligations.

                           (l)      If the Debtor fails to effect and keep in
                                    force insurance covering the Assigned
                                    Collateral as required by Section 6.05 of
                                    the Credit

                                    Agreement or fails to pay any of the
                                    premiums thereon when due, the Agent may
                                    (but shall not be obligated to) do so for
                                    the account of the Debtor and add the cost
                                    thereof to the Secured Obligations. The
                                    Debtor hereby collaterally assigns and sets
                                    over to the Agent (for the benefit of the
                                    Agent, the Lenders and the L/C Issuer) all
                                    monies which may become payable on account
                                    of all insurance covering the Assigned
                                    Collateral, including without limitation any
                                    return of unearned premiums which may be due
                                    upon cancellation of any such insurance.
                                    Prior to the occurrence of a Default or
                                    Event of Default, if the Agent determines in
                                    its reasonable discretion that the Assigned
                                    Collateral may be satisfactorily repaired or
                                    replaced, then the proceeds of any insurance
                                    payment may be used by the Debtor to repair
                                    or replace the damaged Assigned Collateral.
                                    After the occurrence, and during the
                                    continuance, of an Event of Default, the
                                    Agent may direct the insurers to pay
                                    directly to the Agent (for the benefit of
                                    the Agent, the Lenders and the L/C Issuer)
                                    any amount so due. The Agent, its officers,
                                    employees and agents, are hereby appointed
                                    the attorneys-in-fact of the Debtor to
                                    endorse any draft, check, instrument or
                                    other item of payment that may be payable to
                                    the Debtor in order to collect the proceeds
                                    of such insurance or any return of unearned
                                    premiums. Subject to the third sentence of
                                    this subparagraph 1(l) and to paragraph 8
                                    hereof, any such proceeds or returns of
                                    unearned premiums shall be applied by Agent
                                    first to the payment of the Notes and then,
                                    in such order and manner as the Agent shall
                                    elect in its sole discretion, to the payment
                                    of the other Secured Obligations; any
                                    balance of insurance proceeds or unearned
                                    premiums remaining in the possession of the
                                    Agent after payment in full of the Secured
                                    Obligations shall be paid to the Debtor or
                                    its order as the Debtor shall instruct the
                                    Agent in writing.

                           (m)      Neither the value of the Inventory upon
                                    disposition thereof, nor the ability to
                                    freely transfer the Inventory, is limited by
                                    any licenses, franchises, trademarks,
                                    royalty agreements, or other general
                                    intangible or contract right, to which
                                    Debtor is a party or which is otherwise
                                    applicable to Debtor.

                  2. The Debtor agrees that for so long as any of the Secured
Obligations remains unpaid or unperformed and until the Revolving Credit
Commitment is terminated, the Debtor shall perform in all material respects all
obligations, covenants, conditions and agreements to be performed by it relating
to the Assigned Collateral.

                  3. Upon the reasonable request of the Agent at any time after
the execution of this Security Agreement, the Debtor agrees to establish within
sixty (60) days of such request a lockbox arrangement with the Agent and to
execute and deliver to Agent one or more lockbox agreements (collectively, the
"Lockbox Agreement"), each in form and substance satisfactory to the Agent and
its counsel. The Debtor agrees (i) to promptly notify and direct all Account
Debtors to remit all payments on Accounts directly to the lockbox or lockboxes
established under the Lockbox Agreement and (ii) upon the occurrence of, and
during the continuance of, a

Default or an Event of Default and the request of the Agent, to promptly notify
all Account Debtors of the assignment and pledge to the Agent (for the benefit
of the Agent, the L/C Issuer and the Lenders) of, and the grant to the Agent
(for the benefit of the Agent, the L/C Issuer and the Lenders) of liens and
security interests upon and in, the Accounts and the other Assigned Collateral.
To the extent that any law or custom or any contract or agreement with any
Account Debtors requires notice to or the approval of such Account Debtors in
order to perfect such assignment of and security interest in the Accounts, the
Debtor agrees to give such notice or obtain such approval promptly. If the Agent
learns that the Debtor has failed to give such notice or direction to any of the
Account Debtors, then the Agent may itself so notify the Account Debtors (or any
of them). This Security Agreement shall be sufficient evidence of such right and
the Account Debtors may rely hereon and shall be under no obligation to see to
the application of such moneys or other property by the Agent. The Agent is, and
its duly authorized agents are, hereby authorized by the Debtor to endorse for
and on the Debtor's behalf and deposit all drafts and checks payable to the
Debtor in the lockbox established pursuant to the Lockbox Agreement.

                  All checks, drafts, acceptances, notes, cash and other forms
of payment received from Account Debtors in payment on account of Accounts and
transmitted to the lockbox established pursuant to the Lockbox Agreement or
otherwise to the Agent will be deposited in a cash collateral account opened and
maintained pursuant to the Lockbox Agreement. The Debtor acknowledges and agrees
that the cash collateral account will be maintained for the convenience and
benefit of the Agent (for the benefit of the Agent, the L/C Issuer and the
Lenders) and that the Debtor does not, and shall not, have any rights or
interest in the cash collateral account or the lockbox account established
pursuant to the Lockbox Agreement, or any credits thereto or proceeds thereof,
except upon the payment in full of the Lender Obligations.

                  4. The Debtor will faithfully preserve and protect the Agent's
security interests and liens in and on the Assigned Collateral. At the request
of the Agent, the Debtor will, at its own cost and expense, cause such security
interests as are governed by the Uniform Commercial Code to be perfected and to
continue to be perfected so long as the Secured Obligations or any portion
thereof are outstanding and unpaid or unperformed and until the Revolving Credit
Commitment is terminated; and, at the request of the Agent, the Debtor will, at
its own cost and expense, cause such liens and security interests as are
governed by laws or regulations other than the Uniform Commercial Code to be
perfected and to continue to be perfected to the fullest extent permitted by
such laws or regulations, so long as the Secured Obligations or any portion
thereof are outstanding and unpaid or unperformed and until the Revolving Credit
Commitment is terminated.

                  Without limiting the foregoing:

                           (a)      Upon request of the Agent, the Debtor will
                                    join in the execution of all financing
                                    statements, continuation statements, and
                                    other documents required by the Agent to
                                    evidence and perfect all of the liens and
                                    security interests granted hereby or
                                    pursuant hereto and the Debtor shall pay the
                                    cost of filing or recording such in all
                                    public offices where deemed necessary by the
                                    Agent;

                           (b)      Upon the request of the Agent, Debtor will
                                    promptly furnish all documents, affidavits
                                    and other papers reasonably required by

                                    the Agent to further evidence or to perfect
                                    the liens and the security interests granted
                                    hereby or pursuant hereto; and

                           (c)      Upon the request of the Agent, immediately
                                    upon the Debtor's receipt of any portion of
                                    the Assigned Collateral which itself, or the
                                    ownership of which, is or becomes evidenced
                                    by Chattel Paper, a Document, an Instrument,
                                    an agreement, or other writing, including
                                    but not limited to promissory notes,
                                    documents of title, trade acceptances and
                                    warehouse receipts (herein referred to as
                                    the "Special Collateral"), the Debtor shall
                                    deliver the original thereof to the Agent
                                    (for the benefit of the Agent, the Lenders
                                    and the L/C Issuer), together with
                                    appropriate endorsements or other specific
                                    evidence, in form and substance acceptable
                                    to the Agent, of the assignment thereof to
                                    the Agent (for the benefit of the Agent, the
                                    Lenders and the L/C Issuer).

                  Effective upon an Event of Default, the Debtor hereby makes,
constitutes and appoints the Agent (for the benefit of the Agent, the Lenders
and the L/C Issuer) and any of its officers, employees and agents the true and
lawful agent and attorney-in-fact of the Debtor, with full power of
substitution, to sign the name of the Debtor to all financing statements and all
other chattel paper, instruments and documents, and all amendments and
modifications thereof and supplements thereto, in connection with the grant,
perfection, continuation of perfection and protection of the liens and security
interests granted hereby or pursuant hereto.

                  5. Upon the reasonable request of the Agent, the Debtor agrees
that within thirty (30) days after the end of each Fiscal Quarter, the Debtor
shall deliver, or cause to be delivered, to the Agent (i) a complete and
accurate list in all material respects as of the last day of such Fiscal Quarter
of all Accounts, including the names and addresses of the Account Debtors, the
dates when the Accounts first became due, the amount of any offsets or claims of
the Account Debtors with a notation indicating whether or not disputed by the
Debtor, and such additional information as the Agent may from time to time
reasonably request, and (ii) a complete and accurate list in all material
respects as of the last day of such Fiscal Quarter of all Inventory of the
Debtor, the location of such Inventory and such additional information
concerning the Inventory as the Agent may from time to time reasonably request.

                  6. The Debtor will at all times keep, or cause to be kept,
accurate and complete books and records (in all material respects) relating to
the Assigned Collateral; and from time to time during normal business hours, the
Agent, or any of its representatives, shall have the right upon reasonable prior
notice and other reasonable terms and conditions to inspect the Assigned
Collateral and to make extracts from the books and records relating to the
Assigned Collateral. The Debtor shall promptly furnish, or cause to be
furnished, to the Agent such data and information and copies of such papers and
documents relating to the Assigned Collateral as the Agent may reasonably
request from time to time and in such form and substance as may be reasonably
requested. The Debtor will promptly deliver to the Agent all written notices,
and will promptly give the Agent written notice of any other notices, received
by it with respect to a material diminution of the value of the Assigned
Collateral or the impairment of the liens and security interests of the Agent
(on behalf of the Agent, the Lenders and the L/C Issuer) on and in the Assigned
Collateral.

                  7. Upon the occurrence and during the continuance of an Event
of Default, the Agent shall be entitled at its option, at any time and from
time, to time, to exercise any or all of the rights and remedies afforded by the
Uniform Commercial Code or other applicable law as in effect, in addition to
such rights and remedies as are provided herein, in the Notes, in the Credit
Agreement, in any other Loan Document or any other agreement, document or
instrument evidencing or securing the Secured Obligations. The Debtor agrees to
pay to the Agent on demand all expenses including legal expenses and reasonable
attorneys' fees incurred in protecting the Assigned Collateral or enforcing the
Agent's rights and remedies (on behalf of the Agent, the Lenders and the L/C
Issuer), together with interest thereon at the highest rate of interest set
forth on the then outstanding Notes, such liability being one of the Secured
Obligations. To assist the Agent in the implementation of such rights and
remedies the Debtor will, at the Agent's request and at the Debtor's expense,
assemble and prepare for removal at and to places to be designated by the Agent
such items of the Assigned Collateral as are selected by the Agent. Without
limitation upon the foregoing, upon the occurrence and during the continuance of
an Event of Default, the Agent shall have the right to:

                           (a)      take over and direct collection of the
                                    Debtor's Accounts and the proceeds thereof;
                                    give notice of the Agent's security interest
                                    (on behalf of the Agent, the Lenders and the
                                    L/C Issuer) in the Accounts and the proceeds
                                    thereof to the Account Debtors, and the
                                    Agent will have no liability to the Debtor
                                    by reason of giving or not giving such
                                    notice; direct the Account Debtors to make
                                    payments of all monies paid or payable
                                    thereon directly to the Agent (on behalf of
                                    the Agent, the Lenders and the L/C Issuer)
                                    (and, at the request of the Agent, the
                                    Debtor shall indicate on all billings that
                                    payments thereon are to be made to the
                                    Agent); and give any Account Debtors so
                                    notified and directed the receipt of the
                                    Agent for any such payment as full release
                                    for the amount so paid;

                           (b)      enforce collection, either in the name of
                                    the Agent (on behalf of the Agent, the
                                    Lenders and the L/C Issuer) or in the name
                                    of the Debtor, of any or all of the Accounts
                                    and the proceeds thereof by suit or
                                    otherwise; receive, give receipt for,
                                    surrender, release or exchange all or any
                                    part thereof; compromise, settle, extend or
                                    renew (whether or not longer than the
                                    original period) any indebtedness
                                    thereunder; and sell or assign any or all of
                                    the Accounts upon such terms, for such
                                    amounts and at such time or times as the
                                    Agent reasonably deems commercially
                                    advisable;

                           (c)      endorse in the name of the Debtor any
                                    instrument, howsoever received by the Agent,

                                    proceeds);

                           (d)      enter any premises where Assigned Collateral
                                    is located, with process of law and if
                                    necessary, with force, and take possession
                                    and control of the same and take possession
                                    and control of all books and records of the
                                    Debtor relating to the Assigned Collateral;
                                    and keep and store the Assigned Collateral
                                    on such premises until sold (and if such

                                    law, this Security Agreement, the Notes, the

                                    evidencing or securing the Secured
                                    Obligations) or remove the Assigned
                                    Collateral from such premises to the
                                    premises of the Agent or an agent of the
                                    Agent until sold;

                           (e)      sell all or any portion of the Assigned
                                    Collateral at public or private sale at such

                                    and in such manner and upon such terms,
                                    whether for cash or credit, as the Agent in
                                    its sole discretion may determine. The Agent
                                    may purchase all or any of the Assigned
                                    Collateral at such public sale or sales, and

                                    Debtor waives and releases any right to

                                    source or security other than the Assigned
                                    Collateral, under any theory of marshalling
                                    of assets or otherwise; and

                           (f)      do all acts and things permitted by
                                    applicable law which the Agent, in its sole
                                    discretion, deems necessary or advisable to

officers, employees and agents the true and lawful agent and attorney-in-fact of
the Debtor, with full power of substitution, upon the occurrence and during the
continuance of an Event of Default (a) to administer the Assigned Collateral and
proceeds thereof, (b) to receive, and endorse the name of the Debtor upon, any

(g) to take all necessary action to collect Accounts, including bringing legal
proceedings in the name of the Debtor and (h) to do any and all other things and
to take any and all other action (including but not limited to commencing legal
proceedings), in the name and on behalf of the Debtor, which the Agent (on
behalf of the Agent, the Lenders and the L/C Issuer) may deem in its sole
discretion necessary or advisable to carry out the intent of this Security
Agreement.

                  The Debtor agrees that neither the Agent nor any of its
agents, designees or attorneys-in-fact will be liable for any acts of commission
or omission, or for any error of judgment or mistake of fact or law in respect
to the exercise of the powers of attorney granted under this Security Agreement,
including this paragraph 7 and subparagraph 1(l) and paragraph 4 hereof, except
that the Agent shall be liable for the acts of commission or omission of the
Agent, its agents, designees and attorneys-in-fact that constitute recklessness
or willful misconduct. The powers of attorney granted under this Security
Agreement, including this paragraph 7 and subparagraph 1(l) and paragraph 4
hereof, are coupled with an interest and shall be irrevocable until all Secured
Obligations are paid and performed in full and until the Revolving Credit
Commitment is terminated.

                  No waiver by the Agent of any default shall operate as a
waiver of any other default or of the same default on a future occasion. No
failure or delay on the part of the Agent in the exercise of any power, remedy
or right shall operate as a waiver thereof, nor shall any single or partial
exercise of any power, remedy or right preclude other or further exercise
thereof, or the exercise of any other power, remedy or right. The Agent may
assert any of its powers, rights or remedies successively, concurrently,
independently or cumulatively and all such powers, rights and remedies shall be
non-exclusive.

                  Any requirement of law as to reasonable notification of the
time and place of any public sale, or of the time after which any private sale
or other intended disposition of the Assigned Collateral is to be made, shall be
met by giving the Debtor at least ten (10) days' prior written notice of the
time and place of any such public sale or the time after which any such private
sale or any other intended disposition is to be made.

                  8. After the occurrence of an Event of Default, the Agent
shall apply the proceeds of any sale of or other disposition or realization upon
the Assigned Collateral as follows:

                           (a)      First, to the payment or reimbursement of
                                    all reasonable advances, expenses and
                                    disbursements of the Agent (including,
                                    without limitation, the reasonable fees and
                                    disbursements of its counsel and agents)
                                    incurred in connection with the
                                    administration and enforcement of, or the
                                    preservation of, any of the Agent's, any
                                    Lender's or the L/C Issuer's rights, powers
                                    and remedies under this Security Agreement,
                                    the Notes, the Credit Agreement, or any
                                    other Loan Documents or other agreement,
                                    document or instrument evidencing or
                                    securing the Secured Obligations, including
                                    but not limited to the acquisition,
                                    completion, protection, removal, storage,
                                    sale or delivery of the Assigned Collateral;

                           (b)      Second, to the repayment of the Secured
                                    Obligations whether for principal, interest,
                                    fees or expenses, in such order and manner
                                    as the Agent, in its sole discretion, shall
                                    determine; and


                                       12

                           (c)      Third, any balance to be distributed as
                                    required by law.

                  In no event shall the Agent, any Lender or the L/C Issuer be
liable to the Debtor for interest on any surplus. If the proceeds of any such
sale of or other disposition or realization upon the Assigned Collateral are
insufficient to pay and perform the Secured Obligations in full, then the Debtor
shall remain liable for such deficiency.

                  9. The Debtor shall have full responsibility for taking any
and all steps to preserve and protect the Assigned Collateral in its possession
or subject to its control. The Debtor agrees that neither the Agent, the L/C
Issuer nor any of the Lenders, nor any of their respective officers, directors,
employees or agents will be liable for any acts of commission or omission, or
for any error of judgment or mistake of fact or law, with respect to the
preservation or protection of any Assigned Collateral in their custody except
for acts of commission or omission that constitute recklessness or willful
misconduct.

                  10. This Security Agreement is executed only as security for
the Secured Obligations and, therefore, the execution and delivery of this
Security Agreement shall not subject the Agent, the Lenders or the L/C Issuer,
or transfer or pass to the Agent, the Lenders or the L/C Issuer, or in any way
affect or modify, the liability of the Debtor under any or all of the Assigned
Collateral; it being understood and agreed that notwithstanding the execution
and delivery of this Security Agreement, the Notes, the Credit Agreement, or any
other Loan Document or other agreement, document or instrument evidencing or
securing the Secured Obligations (including but not limited to the provisions
hereof and thereof as to the assignment to Agent of right, title and interest in
and to the Assigned Collateral), all of the duties and liabilities of the Debtor
to each and every other party under each and every item of the Assigned
Collateral shall be and remain enforceable by such other party, its successors
and assigns, against, but only against, the Debtor or the Debtor's successors
and assigns other than the Agent, the Lenders or the L/C Issuer, or their
respective representatives, successors and assigns.

                  11. Upon the full discharge and satisfaction of the Secured
Obligations (other than Contingent Lender Obligations), the termination or
cancellation of all outstanding Letters of Credit and the termination of the
Revolving Credit Commitment, (a) all right, title and interest herein assigned
to the Agent, the Lenders or the L/C Issuer, shall terminate, and all right,
title and interest of the Agent, the Lenders or the L/C Issuer in and to each
and every one of the items of Assigned Collateral shall revert to the Debtor and
(b) the Agent shall, at the expense of Debtor, file all requisite termination
statements and do all such other acts as are reasonably required of it to
evidence the termination of the liens and security interests granted hereby or
pursuant hereto. For purposes of this Security Agreement, the term "Contingent
Lender Obligations" shall mean at any time of determination any Lender
Obligations which at such time are contingent obligations under indemnification
provisions of the various Loan Documents which survive indefinitely. Lender
Obligations under such indemnification provisions shall not be considered to be
Contingent Lender Obligations if (x) an unsatisfied claim for payment has been
made under such indemnification provisions at or before such time, or (y) a
proceeding is pending or threatened in writing at such time which may give rise
to a claim under such indemnification provisions.

                  12. Any notice or other communication required hereunder shall
be in writing, and shall be served, given or delivered by (i) registered or

Such notice or other communication shall be deemed to have been duly given or
served on the date on which delivered.

                  13. The Agent, the L/C Issuer or any Lender may have or in the
future may hold other security and/or guaranties to secure all or any part of
the Secured Obligations, but it is specifically understood and agreed that
neither the execution and delivery of this Security Agreement nor the holding of
any other security and/or guaranty shall at any time or in any way operate to
prevent or hinder the Agent, the L/C Issuer or any Lender from resorting first
to such other security and/or guaranty or first to the Assigned Collateral, or
first from time to time to both; and the Agent (on behalf of the Agent, the
Lenders and the L/C Issuer) may from time to time as the Agent sees fit, in the
Agent's sole and uncontrolled discretion, resort to all or any



                                       14

part of the Assigned Collateral without resorting to all or any other security
and/or guaranty securing such Secured Obligations, or to all or any part of any
other security and/or guaranty securing the Secured Obligations without
resorting to all or any part of the Assigned Collateral, and such action on the
Agent's part shall not in any way be considered as a waiver of any of the
benefits or rights of the Agent relating to the Assigned Collateral or such
other security and/or guaranties.

                  14. This Security Agreement shall be binding upon the Debtor
and the successors and assigns of the Debtor, and shall inure to the benefit of
the Agent, the Lenders and the L/C Issuer, and their respective successors and
assigns.

                  15. Whenever possible each provision of this Security
Agreement shall be interpreted in such manner as to be effective and valid under
applicable law but if any provision of this Security Agreement or any part of
such provision shall be prohibited by or invalid under applicable law, such
provision or part thereof shall be ineffective to the extent of such prohibition
or invalidity without invalidating the remainder of such provision or the
remaining provisions of this Security Agreement.

                  16. The obligations of the Debtor under this Security
Agreement, and the grant of security interests hereunder to the Agent for the
benefit of Agent, the Lenders and the L/C Issuer, shall be continuing,
unconditional, irrevocable and absolute and shall be independent of any other
collateral given by the Debtor to secure the Secured Obligations or of any
obligations of, and any security interests granted by, any guarantor of the
repayment of the Secured Obligations, and, without limiting the generality of
the foregoing, shall not be released, discharged or otherwise affected by any of
the following matters and no right or remedy of the Agent, the Lenders or the
L/C Issuer hereunder shall be in any way prejudiced or adversely affected by any
of the following matters (whether or not the Agent, the Lenders or the L/C
Issuer shall make any reservation of rights against, give or attempt to give any
notice to, or request or obtain any further assent of the Debtor with respect to
any of the following matters):

                                    Document, or any other document, instrument
                                    or agreement evidencing or securing the
                                    Secured Obligations;

                                    evidencing or securing the Secured
                                    Obligations;

                                    security, or of any guarantee or other
                                    liability of any third party, for any of the
                                    Secured Obligations or any other obligation
                                    of the Debtor under the Notes, the Credit

                                    other document, instrument or agreement
                                    evidencing or securing the Secured
                                    Obligations;

                                    insolvency, bankruptcy, reorganization or
                                    other similar proceeding affecting the
                                    Debtor or its assets (irrespective of any
                                    release or deferral of the liability of any
                                    guarantor of the Secured Obligations, to pay

                                    make a written report to the Agent of such
                                    physical inventory within forty-five (45)
                                    days after the taking of such physical
                                    count. The Debtor shall promptly furnish to
                                    the Agent all such additional information
                                    and documents (including, without
                                    limitation, invoices, purchase orders,
                                    shipping and receipt records and inventory
                                    logs) as the Agent may from time to time
                                    reasonably request.

                           (f)      The Debtor will not invoice any Person
                                    responsible for the payment or other
                                    performance of any Account (each, an
                                    "Account Debtor", and collectively the
                                    "Account Debtors") or maintain the records
                                    of the Debtor relating to the Assigned
                                    Collateral in any name other than its proper
                                    corporate name, except such new name(s) as
                                    it may establish in accordance with
                                    subparagraph (g) below.

                           (g)      If the Debtor desires to establish a new
                                    location for its principal executive office
                                    and place of business or to establish a new
                                    name or names in which it may invoice
                                    Account Debtors or maintain records
                                    concerning the Assigned Collateral, then the
                                    Debtor shall first, with respect to each
                                    such new location or name:

                                    (1)     give the Agent prior written notice
                                            of its intention to do so and
                                            provide the Agent with such
                                            information in connection therewith
                                            as the Agent may reasonably request;
                                            and

                                    (2)     take such action, reasonably
                                            satisfactory to the Agent, as may be
                                            necessary to maintain at all times
                                            the perfection and priority of the
                                            liens and security interests granted
                                            to the Agent (for the benefit of
                                            Agent, Lenders and L/C Issuer) under
                                            this Security Agreement or pursuant
                                            hereto.

                           (h)      The Agent may at any time, with notice to
                                    the Debtor, verify with any Account Debtors
                                    or any other Person, the status of any
                                    Account. The Debtor from time to time will
                                    execute and deliver such instruments and
                                    take all such action as the Agent may
                                    reasonably request in order to effectuate
                                    the purposes of this subparagraph (h).

                           (i)      The Debtor shall promptly notify the Agent
                                    of all disputes (including without
                                    limitation any rejection or revocation of
                                    acceptance of goods) between the Debtor and
                                    any Account Debtor concerning any amount in
                                    excess of $1,000,000 due and owing under any
                                    single Account or in excess of $2,000,000 in
                                    the aggregate due and owing under all
                                    Accounts from all Account Debtors, including
                                    the reason for the disputes, all claims
                                    related thereto and the amounts in
                                    controversy. The Debtor will promptly notify
                                    the Agent if the Debtor has notice or
                                    knowledge of claims or materially adverse
                                    changes which will or would be reasonably
                                    likely to affect the ultimate collectibility
                                    of any or all of the Accounts of an Account
                                    Debtor then obligated to pay the Debtor in
                                    excess of $1,000,000 in the aggregate. The
                                    Debtor shall not accept any return of
                                    Inventory the sale of which generated an
                                    Account on which the Account Debtor is then
                                    obligated to pay an amount in excess of
                                    $1,000,000, and shall not accept any returns
                                    of Inventory the sale of which together with
                                    all other sales of Inventory generated
                                    Accounts on which all Account Debtors are
                                    obligated to pay an amount in excess of
                                    $2,000,000 in the aggregate, without the
                                    prior written consent of the Agent.

                           (j)      The Debtor will not remove or permit the
                                    removal of any of the Assigned Collateral
                                    consisting of Equipment and Fixtures from
                                    the locations shown on Schedule 2, and will
                                    not locate any Equipment or Fixtures at
                                    locations other than the locations shown on
                                    Schedule 2, except for asset dispositions
                                    which are specifically permitted pursuant to
                                    Section 7.05 of the Credit Agreement,
                                    without the prior written consent of the
                                    Agent, which consent will not be
                                    unreasonably withheld. The Debtor shall
                                    provide to the Secured Party promptly upon
                                    request adequate evidence that any removal
                                    or location of any such Assigned Collateral
                                    was permitted by such Section 7.05, and
                                    shall ensure that any replacement

                                    Equipment and Fixtures are free and clear of
                                    all Liens, except for Permitted Liens.

                           (k)      The Debtor shall fully comply at all times
                                    with the provisions of Section 6.04 of the
                                    Credit Agreement as if set forth fully
                                    herein. If the Debtor fails to comply with
                                    the provisions of Section 6.04 of the Credit
                                    Agreement, the Agent may (but shall not be
                                    obligated to) pay any taxes, levies or
                                    impositions relative to the Assigned
                                    Collateral, for the account of the Debtor
                                    and add the amounts thereof to the Secured
                                    Obligations.

                           (l)      The Debtor shall fully comply at all times
                                    with the provisions of Section 6.05 of the
                                    Credit Agreement as if set forth fully
                                    herein. If the Debtor fails to effect and
                                    keep in force insurance covering the
                                    Assigned Collateral as required by Section
                                    6.05 of the Credit Agreement or fails to pay
                                    any of the premiums thereon when due, the
                                    Agent may (but shall not be obligated to) do
                                    so for the account of the Debtor and add the
                                    cost thereof to the Secured Obligations. The
                                    Debtor hereby collaterally assigns and sets
                                    over to the Agent (for the benefit of Agent,
                                    Lenders and L/C Issuer) all monies which may
                                    become payable on account of all insurance
                                    covering the Assigned Collateral, including
                                    without limitation any return of unearned
                                    premiums which may be due upon cancellation
                                    of any such insurance. Prior to the
                                    occurrence of a Default or Event of Default,
                                    if the Agent determines in its reasonable
                                    discretion that the Assigned Collateral may
                                    be satisfactorily repaired or replaced, then
                                    the proceeds of any insurance payment may be
                                    used by the Debtor to repair or replace the
                                    damaged Assigned Collateral. After the
                                    occurrence, and during the continuance, of
                                    an Event of Default, the Debtor may direct
                                    the insurers to pay directly to the Agent
                                    (for the benefit of Agent, Lenders and L/C
                                    Issuer) any amount so due. The Agent, its
                                    officers, employees and agents, are hereby
                                    appointed the attorneys-in-fact of the
                                    Debtor to endorse any draft, check,
                                    instrument or other item of payment that may
                                    be payable to the Debtor in order to collect
                                    the proceeds of such insurance or any return
                                    of unearned premiums. Subject to the third
                                    sentence of this subparagraph (l) and to
                                    paragraph 8 hereof, any such proceeds or
                                    returns of unearned premiums shall be
                                    applied by Agent first to the payment of the
                                    Note and then, in such order and manner as
                                    the Agent shall elect in its sole
                                    discretion, to the payment of the other
                                    Secured Obligations; any balance of
                                    insurance proceeds or unearned premiums
                                    remaining in the possession of the Agent
                                    after payment in full of the Secured
                                    Obligations shall be paid to the Debtor or
                                    its order as the Debtor shall instruct the
                                    Agent in writing.

                           (m)      Neither the value of the Inventory upon
                                    disposition thereof, nor the ability to
                                    freely transfer the Inventory, is limited by
                                    any licenses, franchises, trademarks,

                                    (i)      The Debtor shall permit any of the
                                             officers or authorized employees or
                                             representatives of the Agent or any
                                             of the Lenders to visit and inspect
                                             any of the properties of the
                                             Debtor, and to examine and make
                                             excerpts from its books and records
                                             and discuss its respective business
                                             affairs, finances and accounts with
                                             its officers, all in such detail
                                             and at such times and as often as
                                             the Agent or any of the Lenders may
                                             reasonably request, provided that
                                             each Lender shall provide the
                                             Debtor and the Agent with
                                             reasonable notice prior to any
                                             visit or inspection and only the
                                             Agent and its authorized employees
                                             or representatives are permitted to
                                             conduct audits.

                                    (ii)     In addition to the visitation
                                             rights set forth in item (i) above
                                             or item (iii) below, so long as no
                                             Default or Event of Default has
                                             occurred and is continuing, the
                                             Debtor shall permit any of the
                                             officers or authorized employees or
                                             representatives of the Agent to
                                             visit the properties of the Debtor
                                             one (1) time in each year to
                                             perform audits of Accounts and
                                             Inventory of the Debtor and to
                                             examine and make excerpts from the
                                             applicable books and records of the
                                             Debtor relating to such Accounts
                                             and Inventory.

                                    (iii)    In addition to the visitation
                                             rights set forth in items (i) and
                                             (ii) above, upon the occurrence of,
                                             and during the continuance of, a
                                             Default of an Event of Default, the
                                             Debtor shall permit any of the
                                             officers or authorized employees or
                                             representatives of the Agent to
                                             visit the properties of the Debtor
                                             as often as the Agent reasonably
                                             requests to perform audits of
                                             Accounts and Inventory of the
                                             Debtor and to examine and make
                                             excerpts from the applicable books
                                             and records of the Debtor relating
                                             to such Account and Inventory.

                  2. The Debtor agrees that for so long as any of the Secured
Obligations remains unpaid or unperformed and until the Revolving Credit
Commitment is terminated, the Debtor shall perform in all material respects all
obligations, covenants, conditions and agreements to be performed by it relating
to the Assigned Collateral and shall comply with all Laws (including without
limitation Environmental Laws) in all respects, provided that there shall not be
deemed to be a violation of this provision if any failure to comply with any Law
would not result in fines, penalties, or other similar liabilities or injunctive
relief which in the aggregate would constitute a Material Adverse Change.

                  3. Upon the reasonable request of the Agent at any time after
the execution of this Security Agreement, the Debtor agrees to establish within
sixty (60) days of such request



                                      -9-
<PAGE>   47


a lockbox arrangement with the Agent and to execute and deliver to Agent one or
more lockbox agreements (collectively, the "Lockbox Agreement"), each in form
and substance satisfactory to Agent and its counsel. Debtor agrees (i) to
promptly notify and direct all Account Debtors to remit all payments on Accounts
directly to the lockbox or lockboxes established under the Lockbox Agreement and
(ii) upon the occurrence of, and during the continuance of, a Default or an
Event of Default and the request of the Agent, to promptly notify all Account
Debtors of the assignment and pledge to the Agent (for the benefit of Agent, L/C
Issuer and Lenders) of, and the grant to the Agent (for the benefit of Agent,
L/C Issuer and Lenders) of liens and security interests upon and in, the
Accounts and the other Assigned Collateral. To the extent that any law or custom
or any contract or agreement with any Account Debtors requires notice to or the
approval of such Account Debtors in order to perfect such assignment of and
security interest in the Accounts, the Debtor agrees to give such notice or
obtain such approval promptly. If the Agent learns that the Debtor has failed to
give such notice or direction to any of the Account Debtors, then the Agent may
itself so notify the Account Debtors (or any of them). This Security Agreement
shall be sufficient evidence of such right and the Account Debtors may rely
hereon and shall be under no obligation to see to the application of such moneys
or other property by the Agent. The Agent is, and its duly authorized agents
are, hereby authorized by the Debtor to endorse for and on the Debtor's behalf
and deposit all drafts and checks payable to the Debtor in the lockbox
established pursuant to the Lockbox Agreement.

                  All checks, drafts, acceptances, notes, cash and other forms
of payment received from Account Debtors in payment on account of Accounts and
transmitted to the lockbox established pursuant to the Lockbox Agreement or
otherwise to the Agent will be deposited in a cash collateral account opened and
maintained pursuant to the Lockbox Agreement. The Debtor acknowledges and agrees
that the cash collateral account will be maintained for the convenience and
benefit of the Agent (for the benefit of Agent, L/C Issuer and Lenders) and that
the Debtor does not, and shall not, have any rights or interest in the cash
collateral account or the lockbox account established pursuant to the Lockbox
Agreement, or any credits thereto or proceeds thereof, except upon the payment
in full of the Lender Obligations.

                  4. The Debtor will faithfully preserve and protect the Agent's
security interests and liens in and on the Assigned Collateral. At the request
of the Agent, the Debtor will, at its own cost and expense, cause such security
interests as are governed by the Uniform Commercial Code to be perfected and to
continue to be perfected so long as the Secured Obligations or any portion
thereof are outstanding and unpaid or unperformed and until the Revolving Credit
Commitment is terminated; and, at the request of the Agent, the Debtor will, at
its own cost and expense, cause such liens and security interests as are
governed by laws or regulations other than the Uniform Commercial Code to be
perfected and to continue to be perfected to the fullest extent permitted by
such laws or regulations, so long as the Secured Obligations or any portion
thereof are outstanding and unpaid or unperformed and until the Revolving Credit
Commitment is terminated.

                  Without limiting the foregoing:

                           (a)      Upon request of the Agent, Debtor will join
                                    in the execution of all financing
                                    statements, continuation statements, and
                                    other documents required by the Agent to
                                    evidence and perfect all of the liens and
                                    security interests granted hereby or
                                    pursuant hereto



                                      -10-
<PAGE>   48


                                    and the Debtor shall pay the cost of filing
                                    or recording such in all public offices
                                    where deemed necessary by the Agent;

                           (b)      Upon the request of the Agent, Debtor will
                                    promptly furnish all documents, affidavits
                                    and other papers reasonably required by the
                                    Agent to further evidence or to perfect the
                                    liens and the security interests granted
                                    hereby or pursuant hereto; and

                           (c)      Upon the request of the Agent, immediately
                                    upon the Debtor's receipt of any portion of
                                    the Assigned Collateral which itself, or the
                                    ownership of which, is or becomes evidenced
                                    by Chattel Paper, a Document, an Instrument,
                                    an agreement, or other writing, including
                                    but not limited to promissory notes,
                                    documents of title, trade acceptances and
                                    warehouse receipts (herein referred to as
                                    the "Special Collateral"), the Debtor shall
                                    deliver the original thereof to the Agent
                                    (for the benefit of Agent, Lenders and L/C
                                    Issuer), together with appropriate
                                    endorsements or other specific evidence, in
                                    form and substance acceptable to the Agent,
                                    of the assignment thereof to the Agent (for
                                    the benefit of Agent, Lenders and L/C
                                    Issuer).

                  Effective upon an Event of Default, the Debtor hereby makes,
constitutes and appoints the Agent (for the benefit of Agent, Lenders and L/C
Issuer) and any of its officers, employees and agents the true and lawful agent
and attorney-in-fact of the Debtor, with full power of substitution, to sign the
name of the Debtor to all financing statements and all other chattel paper,
instruments and documents, and all amendments and modifications thereof and
supplements thereto, in connection with the grant, perfection, continuation of
perfection and protection of the liens and security interests granted hereby or
pursuant hereto.

                  5. Upon the reasonable request of the Agent, the Debtor agrees
that within thirty (30) days after the end of each fiscal quarter of the Debtor,
the Debtor shall deliver, or cause to be delivered, to the Agent (i) a complete
and accurate list in all material respects as of the last day of such Fiscal
Quarter of all Accounts, including the names and addresses of the Account
Debtors, the dates when the Account first became due, the amount of any offsets
or claims of the Account Debtors with a notation indicating whether or not
disputed by the Debtor, and such additional information as the Agent may from
time to time reasonably request, and (ii) a complete and accurate list in all
material respects as of the last day of such Fiscal Quarter of all Inventory of
the Debtor, the location of such Inventory and such additional information
concerning the Inventory as the Agent may from time to time reasonably request.

                  6. The Debtor will at all times keep, or cause to be kept,
accurate and complete books and records in all material respects relating to the
Assigned Collateral; and from time to time during normal business hours, the
Agent, or any of its representatives, shall have the right upon reasonable prior
notice and other reasonable terms and conditions to inspect the Assigned
Collateral and to make extracts from the books and records relating to the
Assigned Collateral. The Debtor shall promptly furnish, or cause to be
furnished, to the Agent such data and information and copies of such papers and
documents relating to the Assigned Collateral as the Agent may reasonably
request from time to time and in such form and substance as may be reasonably
requested. The Debtor will promptly deliver to the Agent all written notices,
and will promptly give the Agent written notice of any other notices, received
by



                                      -11-

it with respect to a material diminution of the value of the Assigned Collateral
or the impairment of the liens and security interests of the Agent (on behalf of
Agent, Lenders and L/C Issuer) on and in the Assigned Collateral.

                  7. Upon the occurrence and during the continuance of an Event
of Default, the Agent shall be entitled at its option, at any time and from
time, to time to exercise any or all of the rights and remedies afforded by the
Uniform Commercial Code or other applicable law as in effect, in addition to
such rights and remedies as are provided herein, in the Notes, in the Credit
Agreement, in the Subsidiary Guaranty, in any Other Debtor Document or any other
agreement, document or instrument evidencing or securing the Secured
Obligations. The Debtor agrees to pay to the Agent on demand all expenses
including legal expenses and reasonable attorneys' fees incurred in protecting
the Assigned Collateral or enforcing the Agent's rights and remedies (on behalf
of Agent, Lenders and L/C Issuer), together with interest thereon at the highest
rate of interest set forth on the then outstanding Notes, such liability being
one of the Secured Obligations. To assist the Agent in the implementation of
such rights and remedies the Debtor will, at the Agent's request and at the
Debtor's expense, assemble and prepare for removal at and to places to be
designated by the Agent such items of the Assigned Collateral as are selected by
the Agent. Without limitation upon the foregoing, upon the occurrence and during
the continuance of an Event of Default, the Agent shall have the right to:

                           (a)      take over and direct collection of the
                                    Debtor's Accounts and the proceeds thereof;
                                    give notice of the Agent's security interest
                                    (on behalf of Agent, Lenders and L/C Issuer)
                                    in the Accounts and the proceeds thereof to
                                    the Account Debtors, and the Agent will have
                                    no liability to the Debtor by reason of
                                    giving or not giving such notice; direct the
                                    Account Debtors to make payments of all
                                    monies paid or payable thereon directly to
                                    the Agent (on behalf of Agent, Lenders and
                                    L/C Issuer) (and, at the request of the
                                    Agent, the Debtor shall indicate on all
                                    billings that payments thereon are to be
                                    made to the Agent); and give any Account
                                    Debtors so notified and directed the receipt
                                    of the Agent for any such payment as full
                                    release for the amount so paid;

                           (b)      enforce collection, either in the name of
                                    the Agent (on behalf of Agent, Lenders and
                                    L/C Issuer) or in the name of the Debtor, of
                                    any or all of the Accounts and the proceeds
                                    thereof by suit or otherwise; receive, give
                                    receipt for, surrender, release or exchange
                                    all or any part thereof; compromise, settle,
                                    extend or renew (whether or not longer than
                                    the original period) any indebtedness
                                    thereunder; and sell or assign any or all of
                                    the Accounts upon such terms, for such
                                    amounts and at such time or times as the
                                    Agent reasonably deems commercially
                                    advisable;

                           (c)      endorse in the name of the Debtor any
                                    instrument, howsoever received by the Agent,

                                    agent of the Agent until sold;

                                    Collateral at public or private sale at such

                                    its sole discretion may determine. The Agent
                                    may purchase all or any of the Assigned
                                    Collateral at such public sale or sales, and

                                    Debtor waives and releases any right to
                                    require the Agent to collect the Secured
                                    Obligations or any part thereof, from a
                                    source or security other than the Assigned
                                    Collateral, under any theory of marshalling
                                    of assets or otherwise; and

                           (f)      do all acts and things permitted by
                                    applicable law which the Agent, in its sole
                                    discretion, deems necessary or advisable to
                                    fulfill or cause the fulfillment of the
                                    Debtor's obligations hereunder and under the
                                    Notes, the Credit Agreement, the Subsidiary
                                    Guaranty, the Other Debtor Documents and any
                                    other agreement, document or instrument
                                    evidencing or securing the Secured
                                    Obligations.

                  The Debtor hereby makes, constitutes and appoints the Agent
(on behalf of Agent, Lenders and L/C Issuer) and any of its officers, employees
and agents the true and lawful agent and attorney-in-fact of the Debtor, with
full power of substitution, upon the occurrence and during the continuance of an
Event of Default (a) to administer the Assigned Collateral and proceeds thereof,
(b) to receive, and endorse the name of the Debtor upon, any notes, checks,
acceptances, drafts, money orders, instruments or other documents relating to
the Assigned Collateral and to effect the deposit and collection thereof for
application to the payment of the Secured Obligations in such order and manner
as the Agent shall elect in its sole discretion, (c) to endorse the Debtor's
name on any bill of lading, receipt, freight item or similar document, (d) to
sign the name of the Debtor to notices to Account Debtors, and to assignments
and notices of assignments and to all other instruments and documents, and all
amendments and modifications thereof and supplements thereto, relating to the
Assigned Collateral, and to receive, open and dispose of mail addressed to the
Debtor and in connection therewith, to execute and deliver notices and
authorizations, in the name of the Debtor, as the United States Postal
Department or other agency may require, (e) to send verifications to any Account
Debtors to verify the status of any Account payable by such Account Debtors and
to sign the name of the Debtor to all audit inquiries made of Account Debtors,
to all information



                                      -13-
<PAGE>   51


release authorizations in connection therewith, to all applications for
documents of title, title certificates and similar documents, to any notice of
claim, satisfaction or release in connection with any Account, and to any proof
of claim in bankruptcy or similar document, (f) to settle, adjust or compromise
any Account or any legal action involving any other Assigned Collateral, (g) to
take all necessary action to collect Accounts, including bringing legal
proceedings in the name of the Debtor and (h) to do any and all other things and
to take any and all other action (including but not limited to commencing legal
proceedings), in the name and on behalf of the Debtor, which the Agent (on
behalf of Agent, Lenders and L/C Issuer) may deem in its sole discretion
necessary or advisable to carry out the intent of this Security Agreement.

                  The Debtor agrees that neither the Agent nor any of its
agents, designees or attorneys-in-fact will be liable for any acts of commission
or omission, or for any error of judgment or mistake of fact or law in respect
to the exercise of the powers of attorney granted under this Security Agreement,
including this paragraph 7 and subparagraph 1(l) and paragraph 4 hereof, except
that the Agent shall be liable for the acts of commission or omission of the
Agent, its agents, designees and attorneys-in-fact that constitute recklessness
or willful misconduct. The powers of attorney granted under this Security
Agreement, including this paragraph 7 and subparagraph 1(l) and paragraph 4
hereof, are coupled with an interest and shall be irrevocable until all Secured
Obligations are paid and performed in full and until the Revolving Credit
Commitment is terminated.

                  No waiver by the Agent of any default shall operate as a
waiver of any other default or of the same default on a future occasion. No
failure or delay on the part of the Agent in the exercise of any power, remedy
or right shall operate as a waiver thereof, nor shall any single or partial
exercise of any power, remedy or right preclude other or further exercise
thereof, or the exercise of any other power, remedy or right. The Agent may
assert any of its powers, rights or remedies successively, concurrently,
independently or cumulatively and all such powers, rights and remedies shall be
non-exclusive.

                  Any requirement of law as to reasonable notification of the
time and place of any public sale, or of the time after which any private sale
or other intended disposition of the Assigned Collateral is to be made, shall be
met by giving the Debtor at least ten (10) days' prior written notice of the
time and place of any such public sale or the time after which any such private
sale or any other intended disposition is to be made.

                  8. After the occurrence of an Event of Default, the Agent
shall apply the proceeds of any sale of or other disposition or realization upon
the Assigned Collateral as follows:

                           (a) First, to the payment or reimbursement of all
reasonable advances, expenses and disbursements of the Agent (including, without
limitation, the reasonable fees and disbursements of its counsel and agents)
incurred in connection with the administration and enforcement of, or the
preservation of, any of the Agent's, any Lender's or the L/C Issuer's rights,
powers and remedies under this Security Agreement, the Notes, the Credit
Agreement, the Subsidiary Guaranty or any Other Debtor Documents or other
agreement, document or instrument evidencing or securing the Secured
Obligations, including but not limited to the acquisition, completion,
protection, removal, storage, sale or delivery of the Assigned Collateral;


                                      -14-
<PAGE>   52


                           (b) Second, to the repayment of the Secured
Obligations whether for principal, interest, fees or expenses, in such order and
manner as the Agent, in its sole discretion, shall determine; and

                           (c) Third, any balance to be distributed as required
by law.

                  In no event shall the Agent, any Lender or the L/C Issuer be
liable to the Debtor for interest on any surplus. If the proceeds of any such
sale of or other disposition or realization upon the Assigned Collateral are
insufficient to pay and perform the Secured Obligations in full, then the Debtor
shall remain liable for such deficiency. Notwithstanding any other provision of
this Security Agreement to the contrary, only 80% of the proceeds of the
disposition of any Inventory shall be applied to repay the Secured Obligations
and the other 20% of such proceeds shall be returned to the Debtor free of the
Lien of this Security Agreement pursuant to this paragraph 8. In accordance with
the provisions of clause (viii)(a) of the definition of "Permitted Liens"
contained within the Indenture, the amount of the Secured Obligations secured by
Inventory shall be deemed to not exceed 80% of the fair market value of such
Inventory at any one time.

                  9. The Debtor shall have full responsibility for taking any
and all steps to preserve and protect the Assigned Collateral in its possession
or subject to its control. The Debtor agrees that neither the Agent, Lenders or
L/C Issuer, nor any of their respective officers, directors, employees or agents
will be liable for any acts of commission or omission, or for any error of
judgment or mistake of fact or law, with respect to the preservation or
protection of any Assigned Collateral in their custody except for acts of
commission or omission that constitute recklessness or willful misconduct.

                  10. This Security Agreement is executed only as security for
the Secured Obligations and, therefore, the execution and delivery of this
Security Agreement shall not subject the Agent, Lenders or L/C Issuer, or
transfer or pass to the Agent, Lenders or L/C Issuer, or in any way affect or
modify, the liability of the Debtor under any or all of the Assigned Collateral;
it being understood and agreed that notwithstanding the execution and delivery
of this Security Agreement, the Notes, the Credit Agreement, the Subsidiary
Guaranty or any Other Debtor Document or other agreement, document or instrument
evidencing or securing the Secured Obligations (including but not limited to the
provisions hereof and thereof as to the assignment to Agent of right, title and
interest in and to the Assigned Collateral), all of the duties and liabilities
of the Debtor to each and every other party under each and every item of the
Assigned Collateral shall be and remain enforceable by such other party, its
successors and assigns, against, but only against, the Debtor or the Debtor's
successors and assigns other than the Agent, Lenders or L/C Issuer, or their
respective representatives, successors and assigns.

                  11. Upon the full discharge and satisfaction of the Secured
Obligations (other than Contingent Lender Obligations), the termination or
cancellation of all outstanding Letters of Credit and the termination of the
Revolving Credit Commitment, (a) all right, title and interest herein assigned
to the Agent, Lenders or L/C Issuer, shall terminate, and all right, title and
interest of the Agent, Lenders or L/C Issuer in and to each and every one of the
items of Assigned Collateral shall revert to the Debtor and (b) the Agent shall,
at the expense of Debtor, file all requisite termination statements and do all
such other acts as are reasonably required of it to evidence the termination of
the liens and security interests granted hereby or pursuant hereto. For purposes
of this Security Agreement the term "Contingent Lender Obligations" shall



                                      -15-
<PAGE>   53


mean at any time of determination any Lender Obligations which at such time are
contingent obligations under indemnification provisions of the various Loan
Documents which survive indefinitely. Lender Obligations under such
indemnification provisions shall not be considered to be Contingent Lender
Obligations if (x) an unsatisfied claim for payment has been made under such
indemnification provisions at or before such time, or (y) a proceeding is
pending or threatened in writing at such time which may give rise to a claim
under such indemnification provisions.

                  12. Any notice or other communication required hereunder shall
be in writing, and shall be served, given or delivered by (i) registered or
certified mail, return receipt requested, with proper postage prepaid, (ii) hand

Such notice or other communication shall be deemed to have been duly given or
served on the date on which delivered.

                  13. The Agent, L/C Issuer or any Lender may have or in the
future may hold other security and/or guaranties to secure all or any part of
the Secured Obligations, but it is specifically understood and agreed that
neither the execution and delivery of this Security Agreement nor the holding of
any other security and/or guaranty shall at any time or in any way operate to
prevent or hinder the Agent, L/C Issuer or any Lender from resorting first to
such other security and/or guaranty or first to the Assigned Collateral, or
first from time to time to both; and the Agent (on behalf of Agent, Lenders and
L/C Issuer) may from time to time as the Agent sees fit, in the Agent's sole and
uncontrolled discretion, resort to all or any part of the Assigned Collateral
without resorting to all or any other security and/or guaranty securing such
Secured Obligations, or to all or any part of any other security and/or guaranty
securing the Secured Obligations without resorting to all or any part of the
Assigned Collateral, and such action on the Agent's part shall not in any way be
considered as a waiver of any of the benefits or rights of the Agent relating to
the Assigned Collateral or such other security and/or guaranties.

                  14. This Security Agreement shall be binding upon the Debtor
and the successors and assigns of the Debtor, and shall inure to the benefit of
the Agent, Lenders and L/C Issuer, and their respective successors and assigns.

                  15. Whenever possible each provision of this Security
Agreement shall be interpreted in such manner as to be effective and valid under
applicable law but if any provision of this Security Agreement or any part of
such provision shall be prohibited by or invalid under applicable law, such
provision or part thereof shall be ineffective to the extent of such prohibition
or invalidity without invalidating the remainder of such provision or the
remaining provisions of this Security Agreement.

                  16. The obligations of the Debtor under this Security
Agreement, and the grant of security interests hereunder to the Agent for the
benefit of Agent, the Lenders and the L/C Issuer, shall be continuing,
unconditional, irrevocable and absolute and shall be independent of any
obligations of, and any security interests granted by, the Borrower or any other
Person and, without limiting the generality of the foregoing, shall not be
released, discharged or otherwise affected by any of the following matters and
no right or remedy of the Agent, the Lenders or the L/C Issuer hereunder shall
be in any way prejudiced or adversely affected by any of the following matters
(whether or not the Agent, the Lenders or the L/C Issuer shall make any
reservation of rights against, give or attempt to give any notice to, or request
or obtain any further assent of the Debtor with respect to any of the following
matters):

                           (a)      any extension, renewal, settlement,
                                    compromise, waiver or release in respect of
                                    any of the Secured Obligations or any other
                                    obligation of the Borrower under the Notes,
                                    the Credit Agreement, any other Loan
                                    Document, or any other document, instrument
                                    or agreement evidencing or securing the
                                    Secured Obligations;

                           (b)      any modification or amendment of or

including, without limitation, electrical equipment necessary for the operation
of such buildings and heating, air conditioning and plumbing equipment now or
hereafter attached to, located in or used in connection with those buildings,
structures or other improvements, and owned by the Mortgagor, and including all
of the Mortgagor's right, title and interest (including, purchase options and
similar rights) under any equipment leases which do not prohibit the mortgaging
of such interests (hereinafter collectively called the "IMPROVEMENTS");

                  (c) The Mortgagor's right, title and interest in, to and under
all rights of way, servitudes, permits, licenses, approvals, franchises,

Land and from the Improvements (the "RENTS") including, but not limited to, the
Rents arising or issuing from all leases and subleases now or hereafter entered
into covering all or any part of said Land and or Improvements (the "LEASES"),
all of which Leases and Rents are hereby assigned to the Mortgagee by the
Mortgagor. The foregoing assignment shall include without limitation, cash or
securities deposited under Leases to secure performance of lessees of their
obligations thereunder, whether such cash or securities are to be held until the
expiration of the terms of such leases or applied to one or more installments of
rent coming due prior to the expiration of such terms. The Mortgagee, or any of
its officers, directors, employees and authorized agents as the Mortgagee may
select, is hereby irrevocably appointed attorney-in-fact for the Mortgagor
(without requiring any of them to act as such), such appointment being coupled
with an interest, to collect such Rents, after the occurrence of an Event of
Default. The Mortgagor will execute and deliver to the Mortgagee, on demand,
such assignments and instruments as the Mortgagee may require to implement,

vacation of any street abutting thereon, all of which awards, damages, payments,
compensation, claims and rights are hereby assigned, transferred and set over by
the Mortgagor to the Mortgagee to the fullest extent possible under applicable
laws. The Mortgagee, or any of its officers, directors, employees and authorized
agents as the Mortgagee may select, is hereby irrevocably appointed
attorney-in-fact for the Mortgagor (without requiring any of them to act as
such), such appointment being coupled with an interest, to settle for, with the
consent of the Mortgagor unless an Event of Default has occurred, in which case
the Mortgagor's consent shall not be required, collect and receive any such
awards, damages, payments and compensation from the authorities making the same;

                  (f) The Mortgagor's right, title and interest in, to and under
all property of whatsoever nature now or hereafter situate upon the Mortgaged
Property and used or intended to be used in connection with any Improvement,
including all the Mortgagor's right, title and interest (including, purchase
options and similar rights) under any equipment leases which do not prohibit the
mortgaging of such interests;

                  (g) All proceeds of the conversion, voluntary or involuntary,
of any of the foregoing into cash or liquidated claims;

                  (h) And without limiting any of the other provisions of this
Mortgage, the Mortgagor expressly grants unto the Mortgagee a security interest
in all those portions of the Mortgaged Property which may be subject to the UCC
provisions applicable to secured transactions under the laws of Pennsylvania,
including, without limitation, Accounts, General Intangibles, Goods, Inventory,
Chattel Paper, Documents and Instruments (as such terms are defined in Article 9
of the Uniform Commercial Code), and the Mortgagor will execute and deliver to
the Mortgagee on demand, and hereby irrevocably appoint the Mortgagee or any
officer of the Mortgagee the attorney-in-fact of the Mortgagor (without
requiring any of them to act as such), such appointment being coupled with an
interest, to execute, deliver and file such



                                      -3-
<PAGE>   63


financing statements and other instruments as the Mortgagee may require in order
to perfect and maintain such security interest under the UCC on the aforesaid
collateral.

         To have and to hold the same unto the Mortgagee and its successors and
assigns, forever, for and on behalf of the Lenders and the L/C Issuer.

         Provided, however, that if the Mortgagor shall pay to the Lenders and
the L/C Issuer the Lender Obligations, and if the Mortgagor shall keep and
perform each of its other covenants, conditions and agreements set forth herein
and in the other Loan Documents, then, upon the termination of all obligations,
duties and commitments of the Mortgagor under the Lender Obligations and this
Mortgage, the estate hereby granted and conveyed shall become null and void.

         This Mortgage is an "Open-End Mortgage" as set forth in 42 PA. C.S.A.
Section 8143 and secures obligations up to a maximum principal amount of
indebtedness outstanding at any time equal to $150,000,000, plus accrued and
unpaid interest, including, but not limited to, advances for the payment of
taxes and municipal assessments, maintenance charges, insurance premiums, costs
incurred for the protection of the Mortgaged Property or the lien of this
Mortgage, expenses incurred by the Mortgagee by reason of default by the
Mortgagor under this Mortgage and advances for construction, alteration or
renovation on the Mortgaged Property or for any other purpose, together with all
other sums due hereunder or secured hereby. All notices to be given to the
Mortgagee pursuant to 42 PA. C.S.A. Section 8143 shall be given as set forth in
Section 17 of this Mortgage.

         1. REPRESENTATIONS AND WARRANTIES. The Mortgagor represents and
warrants to the Mortgagee that the Mortgagor has good and marketable title to an
estate in fee simple absolute in the Land and Improvements and has all right,
title and interest in all other property constituting a part of the Mortgaged
Property, in each case free and clear of all Liens, except for Permitted Liens.
This Mortgage is a valid and enforceable first Lien on the Mortgaged Property
(except for Permitted Liens), and the Mortgagee shall, subject to the
Mortgagor's right of possession prior to an Event of Default, quietly enjoy and
possess the Mortgaged Property. The Mortgagor shall preserve such title as it
warrants herein and the validity and priority of the Lien hereof and shall
forever warrant and defend the same to the Mortgagee against the claims of all
Persons and parties whomsoever.

         2. AFFIRMATIVE COVENANTS. Until all of the Lender Obligations shall
have been fully paid, satisfied and discharged and the Credit Facility shall
have terminated, the Mortgagor shall:

                  (a) PAYMENT AND PERFORMANCE OF LENDER OBLIGATIONS. Pay or
cause to be paid and perform all Lender Obligations when due as provided in the
Loan Documents.

                  (b) LEGAL REQUIREMENTS. Promptly comply with and conform in
all material respects to all present and future Laws and all covenants,
restrictions and conditions which may be applicable to the Mortgagor or to any
of the Mortgaged Property (collectively, the "LEGAL REQUIREMENTS").

                  (c) IMPOSITIONS. Except as otherwise permitted by the Credit
Agreement, before interest or penalties are delinquent thereon and otherwise
when due, the Mortgagor shall pay all taxes of every kind and nature, all
charges for any easement or agreement maintained for the benefit of any of the
Mortgaged Property, all general and special assessments



                                      -4-
<PAGE>   64


(including, without limitation, any condominium or planned unit development
assessments, if any), levies, permits, inspection and license fees, all water
and sewer rents and charges, and all other charges and Liens, whether of a like
or different nature, imposed upon or assessed against the Mortgagor or any of
the Mortgaged Property. The obligations referred to in this Section are
hereinafter collectively referred to as the "IMPOSITIONS". The Mortgagor shall
deliver to the Mortgagee evidence acceptable to the Mortgagee of any such
payment, promptly upon any request therefor by the Mortgagee. The Mortgagor's
obligation to pay the Impositions which were imposed upon or assessed against
the Mortgagor or the Mortgaged Property up to any date on which the Mortgagee or
its assignee takes title to the Mortgaged Property, whether through foreclosure,
deed-in-lieu or otherwise, shall survive the Mortgagee's or any assignee's
taking title to the Mortgaged Property through foreclosure, deed-in-lieu or
otherwise.

                  (d) MAINTENANCE OF SECURITY. The Mortgagor shall keep the
Mortgaged Property in good condition and order and in a rentable and tenantable
state of repair and will make or cause to be made, as and when necessary, all
repairs, renewals, and replacements, structural and nonstructural, exterior and
interior, foreseen and unforeseen, ordinary and extraordinary, provided,
however, that no material structural repairs, renewals or replacements shall be
made without the Mortgagee's prior written consent, which consent shall not be
unreasonably withheld or delayed. The Mortgagor shall not remove or demolish the
Mortgaged Property, nor commit or suffer waste with respect thereto, nor permit
the Mortgaged Property to become deserted or abandoned. The Mortgagor shall
permit the Mortgagee and its agents at any time, and from time to time, upon
five (5) days' notice and during normal business hours, to enter upon and visit
the Mortgaged Property for the purpose of inspecting and appraising the same;
provided, however, that no notice of an inspection or appraisal need be given
when a Default or Event of Default exists. The Mortgagor covenants and agrees
not to take or permit any action with respect to the Mortgaged Property which
will in any material manner impair the security of this Mortgage.

                  (e) USE OF MORTGAGED PROPERTY. The Mortgagor shall use, and
permit others to use, the Mortgaged Property only for its present use or such
other uses as permitted by applicable Legal Requirements and approved in writing
by the Mortgagee.

                  (f) BOOKS AND RECORDS. The Mortgagor shall maintain and the
Mortgagee shall have access to, upon five (5) days' prior notice to the
Mortgagor, complete and adequate books of account and other records relating to
the operation and use of the Mortgaged Property as the Mortgagee may require.
The Mortgagor shall permit the Mortgagee to photocopy such books and records.

         3. NEGATIVE COVENANTS. Until all of the Lender Obligations shall have
been fully paid, satisfied and discharged:

                  (a) LEASES. The Mortgagor shall not (i) execute an assignment
or pledge of the Rents and/or the Leases other than in favor of the Mortgagee;
(ii) accept any prepayment of an installment of any Rents more than one (1)
month prior to the due date of such installment; or (iii) enter into or amend
any of the terms of any of the Leases without the Mortgagee's prior written
consent which consent shall not be unreasonably withheld or delayed. Any or all
leases or subleases of all or any part of the Mortgaged Property shall be
subject in all respects to the prior written consent of the Mortgagee, not to be
unreasonably withheld or delayed, shall be subordinated to this Mortgage and to
the rights of the Mortgagee and, together with any and all rents, issues or
profits relating thereto, shall be assigned at the time of execution to the



                                      -5-
<PAGE>   65


Mortgagee as additional collateral security for the Lender Obligations, all in
such form, substance and detail as is satisfactory to the Mortgagee in its sole
discretion. The Mortgagee agrees to execute and deliver any non-disturbance
agreements reasonably requested by the Mortgagor.

                  (b) TRANSFER. The Mortgagor shall not sell, convey or
otherwise transfer any interest in the Mortgaged Property (whether voluntarily
or by operation of law), or agree to do so, without the Mortgagee's prior
written consent. For the purpose of, and without limiting the generality of the
foregoing, the occurrence at any time of any of the following events except as
may be permitted pursuant to the Credit Agreement, without the Mortgagee's prior
written consent, shall be deemed to be an unpermitted transfer of title to the
Mortgaged Property: (i) any sale, conveyance, assignment, or other transfer of
(including installment land sale contracts), or the grant of a security interest
in, all or any part of the legal and/or equitable title to the Mortgaged
Property; (ii) any lease of all or any portion of the Mortgaged Property, except
as may otherwise be permitted under this Mortgage; or (iii) any sale,
conveyance, assignment, or other transfer of, or the grant of a security
interest in, any equity interest of the Mortgagor.

         4. INSURANCE.

                  (a) The Mortgagor shall keep the Mortgaged Property
continuously insured in accordance with the provisions of Section 6.05 of the
Credit Agreement.

                  (b) If the Mortgaged Property is located in an area which has
been identified by any Governmental Authority as a flood hazard area or the
like, then the Mortgagor shall maintain a flood insurance policy covering the
Improvements in an amount not less than the original principal amount of the
Lender Obligations or the maximum limit of coverage available under the federal
program, whichever amount is less.

                  (c) If the Mortgagor shall not at any time comply with the
terms of this Section, irrespective of the passage of any grace period, the
Mortgagee may cure such non-compliance and may purchase such insurance as it may
elect. The Mortgagor shall reimburse the Mortgagee on demand for any costs
incurred by the Mortgagee in connection with any such actions, together with
interest at the rate set forth in Section 2.08(c) of the Credit Agreement. Any
such actions by the Mortgagee shall not constitute a waiver of any
non-compliance of the terms of this Mortgage by the Mortgagor.

         5. RIGHTS OF MORTGAGEE TO INSURANCE PROCEEDS. In the event of loss, the
Mortgagee shall have the exclusive right to adjust and compromise (with the
Mortgagor's consent, which consent shall not be required if an Event of Default
exists), and collect all insurance claims, and no Mortgagor shall adjust,
collect or compromise any claims under said policies without the prior written
consent of the Mortgagee. Each insurer is hereby authorized and directed to make
payment under said policies, including return of unearned premiums, directly to
Mortgagee instead of to the Mortgagor and the Mortgagee jointly, and the
Mortgagor appoints the Mortgagee, or any of its officers, directors, employees
or authorized agents as the Mortgagee may select, as the Mortgagor's
attorney-in-fact to endorse any draft therefor. All insurance proceeds shall be
payable to the Mortgagee and such proceeds may, at the Mortgagee's sole option,
be applied to all or any part of the Lender Obligations and in any order
(notwithstanding that such Lender Obligations may not then otherwise be due and
payable) or to the repair and restoration of any of the Mortgaged Property under
such terms and conditions as the Mortgagee may impose; provided, however, that
if no Default or Event of Default exists,



                                      -6-
<PAGE>   66


and if the Mortgagee determines in its reasonable discretion that the Mortgaged
Property can be satisfactorily repaired or restored, then the insurance proceeds
shall be applied to repair or restore the Mortgaged Property under such terms
and conditions as the Mortgagee may impose. The Mortgagee shall not be deemed to
have elected any option made available pursuant to this Section 5 until such
option is elected specifically in writing. Until so elected, the Mortgagee shall
not in any circumstances be deemed to have waived its right to make such
election.

         6. CONDEMNATION. The Mortgagor, immediately upon obtaining knowledge of
the institution of any proceedings for the condemnation or taking by eminent
domain of any of the Mortgaged Property, shall notify the Mortgagee of the
pendency of such proceedings. The Mortgagee may participate in any such
proceedings and the Mortgagor shall deliver to the Mortgagee all instruments
requested by it to permit such participation. Any award or compensation for
property taken or for damage to property not taken, whether as a result of such
proceedings or in lieu thereof, is hereby assigned to and shall be received and
collected directly by the Mortgagee, and any award or compensation shall be
applied, at the Mortgagee's option, to any part of the Lender Obligations and in
any order (notwithstanding that any of such Lender Obligations may not then be
due and payable) or to the repair and restoration of any of the Mortgaged
Property under such terms and conditions as the Mortgagee may impose; provided,
however, that if no Default or Event of Default exists, and if the Mortgagee
determines in its reasonable discretion that the Mortgaged Property can be
satisfactorily repaired or restored, then the award or compensation shall be
applied to repair or restore the Mortgaged Property under such terms and
conditions as the Mortgagee may impose. The Mortgagee shall not be deemed to
have elected any option made available pursuant to this Section 6 until such
option is elected specifically in writing. Until so elected, the Mortgagee shall
not in any circumstances be deemed to have waived its right to make such
election.

         7. EVENTS OF DEFAULT. The occurrence of any one or more of the
following events shall constitute an "EVENT OF DEFAULT" hereunder:

                  (a) Any "Event of Default" (as defined in the Credit
Agreement) of the Credit Agreement relating to violations of any term,
agreement, covenant, condition set forth in any Loan Document (including,
without limitation, this Mortgage); or

                  (b) The Mortgagor or any other obligor or guarantor of any of
the Lender Obligations, shall at any time deliver or cause to be delivered to
the Mortgagee a notice pursuant to 42 PA. C.S.A. Section 8143 electing to limit
the indebtedness secured by this Mortgage.

         8. RIGHTS AND REMEDIES OF MORTGAGEE. If an Event of Default occurs, the
Mortgagee may, at its option without demand, notice or delay, do one or more of
the following:

                  (a) The Mortgagee may exercise any remedy available to it
pursuant to the Credit Agreement or any of the other Loan Documents;

                  (b) The Mortgagee may (i) institute and maintain an action of
mortgage foreclosure against the Mortgaged Property and the interest of the
Mortgagor therein, (ii) institute and maintain an action on any instruments
evidencing the Lender Obligations or any portion thereof, and (iii) take such
other action at law or in equity for the enforcement of any of the Loan
Documents as the law may allow, and in each such action the Mortgagee shall be
entitled to all costs of suit and attorneys fees;


                                      -7-
<PAGE>   67


                  (c) The Mortgagee may, in its sole and absolute discretion,
and without releasing the Mortgagor or any other obligor or guarantor from any
obligation under any of the Loan Documents and without waiving any Event of
Default: (i) collect any or all of the Rents, including any Rents past due and
unpaid, (ii) perform any obligation or exercise any right or remedy of the
Mortgagor under any Lease, or (iii) enforce any obligation of any tenant of any
of the Mortgaged Property. The Mortgagee may exercise any right under this
subsection (c), whether or not the Mortgagee shall have entered into possession
of any of the Mortgaged Property, and nothing herein contained shall be
construed as constituting the Mortgagee a "mortgagee in possession", unless the
Mortgagee shall have entered into and shall continue to be in actual possession
of the Mortgaged Property. The Mortgagor hereby authorizes and directs each and
every present and future tenant of any of the Mortgaged Property to pay all
Rents directly to the Mortgagee and to perform all other obligations of that
tenant for the direct benefit of the Mortgagee, as if the Mortgagee were the
landlord under the Lease with that tenant, immediately upon receipt of a demand
by the Mortgagee to make such payment or perform such obligations. The Mortgagor
hereby waives any rights, claims or demands it may now or hereafter have against
any such tenant by reason of such payment of Rents or performance of obligations
to the Mortgagee, and any such payment or performance to the Mortgagee shall
discharge the obligations of the tenant to make such payment or performance to
the Mortgagor; and

                  (d) The Mortgagee shall have the right, in connection with the
exercise of its remedies hereunder, to the appointment of a receiver to take
possession and control of the Mortgaged Property and/or to collect the Rents,
without notice and without regard to the adequacy of the Mortgaged Property to
secure the Lender Obligations. A receiver while in possession of the Mortgaged
Property shall have the right to make repairs and to make improvements necessary
or advisable in its or his opinion to preserve the Mortgaged Property, or to
make and keep them rentable to the best advantage, and the Mortgagee may advance
moneys to a receiver for such purposes. Any moneys so expended or advanced by
the Mortgagee or by a receiver shall be added to and become a part of the Lender
Obligations secured by this Mortgage.

         9. APPLICATION OF PROCEEDS. The Mortgagee shall apply the proceeds of
any foreclosure sale of, or other disposition or realization upon, or Rents or
profits from, the Mortgaged Property to satisfy the Lender Obligations in such
order of application as the Mortgagee shall determine in its exclusive
discretion and in a manner consistent with the terms of the Credit Agreement.

         10. SALE IN PARCELS OR UNITS. In case any sale under this Mortgage
occurs by virtue of judicial proceedings, the Mortgaged Property may be sold in
one parcel or unit and as an entity, or in such parcels or units, and in such
manner or order, as the Mortgagee in its sole discretion may elect.

         11. REMEDIES CUMULATIVE. All remedies contained in this Mortgage are
cumulative and the Mortgagee also has all other remedies provided by law or in
equity or in any of the other Loan Documents. No delay or failure by the
Mortgagee to exercise any right or remedy under this Mortgage will be construed
to be a waiver of that right or remedy or a waiver of any Event of Default. The
Mortgagee may exercise any one or more of its rights and remedies without regard
to the adequacy of its security.


                                      -8-
<PAGE>   68


         12. INSTALLMENTS FOR INSURANCE, TAXES AND OTHER CHARGES. Without
limiting the effect of any other provision of this Mortgage, the Mortgagor
shall, after the occurrence of an Event of Default if requested by the
Mortgagee, pay to the Mortgagee monthly, an amount equal to one-twelfth (1/12)
of the annual premiums for the insurance policies referred to hereinabove and
the annual Impositions and any other item which at any time may be or become a
lien upon the Mortgaged Property (the "ESCROW CHARGES"); and on demand, from
time to time, the Mortgagor shall pay to the Mortgagee any additional sums
necessary to pay when due all Escrow Charges. No amount so paid to the Mortgagee
shall be deemed to be trust funds but may be commingled with general funds of
the Mortgagee, nor shall any sums paid bear interest. The Mortgagee shall have
no obligation to pay any insurance premium or Imposition if at any time the
funds being held by the Mortgagee for such premium or Imposition are
insufficient to make such payments and the Mortgagor shall, within ten days of
the date of demand by the Mortgagee, pay the amount of such insufficiency to the
Mortgagee. The Mortgagee shall have the right, at its election, to apply any
amount so held against the Lender Obligations due and payable in such order as
the Mortgagee may deem fit, and the Mortgagor hereby grants to the Mortgagee a
Lien upon and security interest in such amounts for such purpose.

         13. MORTGAGEE'S RIGHT TO PROTECT SECURITY. The Mortgagee is hereby
authorized to do any one or more of the following, irrespective of whether an
Event of Default has occurred: (a) appear in and defend any action or proceeding
purporting to affect the security hereof or the rights or powers of the
Mortgagee hereunder; (b) take such action as the Mortgagee may determine to pay,
perform or comply with any Impositions or Legal Requirements to the extent such
performance or compliance is required pursuant to the terms of this Mortgage, to
cure any Events of Default and to protect its security in the Mortgaged
Property.

         14. MORTGAGEE'S COSTS AND EXPENSES. In the event of an Event of Default
or the exercise by the Mortgagee of any of its rights hereunder, or if the
Mortgagee shall become a party, either as plaintiff or defendant or otherwise,
to any suit or legal proceeding affecting any of the Mortgaged Property or the
Lender Obligations, or if review and approval of any document, or any other
matter related to any of the Lender Obligations, is required by, or requested
of, the Mortgagee, the Mortgagor shall pay to the Mortgagee on demand its costs,
expenses and reasonable attorneys fees incurred in connection therewith. If such
amounts are not paid, they shall be added to the principal secured hereby, shall
be included as part of the Lender Obligations and shall bear interest at the
rate of interest set forth in Section 2.08(c) of the Credit Agreement from the
date of demand.

         15. FURTHER ASSURANCES. The Mortgagor agrees to execute such further
assurances, documents and instruments as may be desirable by the Mortgagee for
the purposes of further evidencing, carrying out and/or confirming this Mortgage
and for all other purposes intended by this Mortgage.

         16. ENVIRONMENTAL MATTERS.

                  (a) The Mortgagor represents and warrants that to the best of
its knowledge (i) the Mortgaged Property is and has been in compliance, in all
material respects, with all applicable local, state and federal environmental
laws, rules and regulations; and (ii) there have been no releases of any
chemical, material, substance or waste which is a threat to the public health,
safety or welfare or the environment or the health of living organisms, or any
hazardous,



                                      -9-
<PAGE>   69


toxic, contaminating or polluting substance as defined by any environmental law,
rule or regulation (individually and collectively "HAZARDOUS SUBSTANCES").

                  (b) Mortgagor will ensure that the Mortgaged Property remains
in compliance, in all material respects, with all local, state and federal
environmental laws, rules and regulations, and that it will not place or permit
to be placed on the Mortgaged Property any Hazardous Substances, except as not
prohibited by applicable environmental laws, rules or regulations, or in such
quantities as to not constitute a hazard to the environment or subject the
Mortgagor to prosecution or liability in connection therewith.

                  (c) Mortgagor will employ in connection with its use of the
Mortgaged Property appropriate technology as the Mortgagor determines reasonably
necessary to maintain compliance in all material respects with any applicable
environmental law, rule or regulation and dispose of any and all Hazardous
Substances generated at the Mortgaged Property only at facilities and with
carriers that maintain valid permits under applicable environmental laws, rules
and regulations.

                  (d) In the event the Mortgagor obtains, gives or receives
notice of any release or threat of release of a reportable quantity of any
Hazardous Substances at the Mortgaged Property or receives any notice of
violation, request for information or notification that it is potentially
responsible for investigation or cleanup of environmental conditions at the
Mortgaged Property, or any demand letter, complaint, order, citation or other
written notice with regard to any Hazardous Substances or violation of any
environmental law, rule or regulation, affecting the Mortgaged Property from any
person or entity, including any state agency responsible in whole or in part for
environmental matters in the state in which the Mortgaged Property is located or
the United States Environmental Protection Agency (any such person or entity is
hereinafter referred to as the "AUTHORITY"), then the Mortgagor shall, within
five (5) days, give written notice of the same to the Mortgagee detailing facts
and circumstances of which the Mortgagor is aware in connection therewith. Such
information is to be provided to allow Mortgagee to protect its security
interest in the Mortgaged Property and is not intended to create any obligation
upon the Mortgagee with respect thereto.

                  (e) Mortgagor shall promptly forward to the Mortgagee copies
of any request for information, notification of material potential liability,
demand letter for information, notification of material potential liability,
demand letter relating to material potential responsibility with respect to the
investigation or cleanup of Hazardous Substances at the Mortgaged Property and
shall continue to forward to the Mortgagee copies of material correspondence
between the Mortgagor and the Authority regarding such claims until the claims
are settled. The Mortgagor shall promptly forward to the Mortgagee copies of all
documents and reports concerning Hazardous Substances at the Mortgaged Property
that the Mortgagor is required to file under any environmental law, rule or
regulation. Such information is to be provided to allow the Mortgagee to protect
its security interest in the Mortgaged Property and is not intended to create
any obligation upon the Mortgagee with respect thereto.

described below as well as all of Grantor's property relating thereto and all

to and relating to such property, and all products thereof and proceeds derived

Exhibit A, together with all of the easements, rights of way, privileges,
liberties, hereditaments, gores, streets, alleys, passages, ways, waters,
watercourses, rights and appurtenances thereunto belonging or appertaining, and
all of the Grantor's estate, right, title, interest, claim and demand whatsoever
therein and in the public streets and ways adjacent thereto, either in law or in
equity (the "LAND");

                  (b) All the buildings, structures and improvements of every
kind and description now or hereafter erected or placed on the Land, and all
facilities, fixtures, machinery, apparatus, appliances, installations, machinery
and equipment, including all building materials to be incorporated into such
buildings, all electrical equipment necessary for the operation of such

                  (c) All rents, issues and profits arising or issuing from the

confirm, maintain and continue the assignment of Rents hereunder;

Deed of Trust, the Grantor, as debtor, expressly grants unto the Mortgagee, as
secured party, a security interest in all those portions of the Property ( as
defined below) which may be subject to the Uniform Commercial Code provisions
applicable to secured transactions under the laws of any state, and the Grantor
will execute and deliver to the Trustee on demand such financing statements and
other instruments as the Trustee may require in order to perfect and maintain
such security interest under the UCC on the aforesaid collateral.

All of Grantor's real and personal property described above, and all of
Grantor's rights, titles and interests in and to and relating to such property,
are hereinafter referred to individually and collectively as the "PROPERTY".

                  TO HAVE AND TO HOLD the Property hereby granted, conveyed and
otherwise transferred unto the Trustee and his successors and assigns IN TRUST
and hereby assigned and pledged to the Beneficiary, its successors and assigns,
to the only proper use and behoof of the Trustee and his successors and assigns
and the Beneficiary and its successors and assigns forever, with power of sale.

                  In the event the Property covered by this Deed of Trust or any
part thereof shall be condemned, taken, injured or destroyed for public use
under the power of eminent domain or otherwise, the Grantor does hereby assign
to the Trustee all damages awarded for the taking of, injury to, destruction of
or damage to the Property or any part thereof, up to the total amount owing and
secured by any and all of the terms of this Deed of Trust. Notwithstanding any
such condemnation, taking, injury or destruction, the indebtedness secured
hereby shall not be reduced until any award or payment thereunder shall have
been actually received and applied by the Trustee to the discharge or reduction
of such indebtedness. The Trustee may apply any such award or payment resulting
from the Property being condemned, taken, injured or destroyed for public use
under the power of eminent domain or otherwise to the reduction of the
indebtedness secured hereby whether or not then due and payable. If the Property
or any part thereof is sold, whether pursuant to this Deed of Trust or
otherwise, prior to the receipt by the Trustee of such award or payment, the
Trustee shall have the right, whether or not a deficiency judgment on any of the
Notes shall have been sought, recovered or denied, to receive such award or
payment, or a portion thereof sufficient to pay the indebtedness secured hereby
and to satisfy the other obligations secured hereby.

                  PROVIDED, HOWEVER, that if Grantor shall pay, or cause to be
paid, to the Beneficiary the principal debts evidenced by the Notes, including
additional loans or advances, and all other sums payable by Grantor to the
Beneficiary and secured hereby, together with interest thereon, and shall keep
and perform, or cause to be kept and performed, each of the other covenants,
conditions and agreements contained in the Notes, the Subsidiary Guaranty and
this Deed of Trust, then this Deed of Trust and the interests hereby granted,
conveyed and otherwise transferred shall become void.

                  THE GRANTOR, the Trustee and the Beneficiary intend and agree
that this Deed of Trust shall secure unpaid balances of any advances, including
but not limited to advances for taxes, assessments, maintenance charges,
insurance premiums, costs incurred for the protection of the Property or the
lien of this Deed of Trust and expenses incurred by the



                                      -4-
<PAGE>   85


Trustee or the Beneficiary by reason of default by the Grantor under this Deed
of Trust, whether any such advances are obligatory or not and whether or not
evidenced by the Notes and whether heretofore made or made in the future.

                  This Deed of Trust is given for the purpose of securing loan
advances to the Borrower pursuant and subject to the terms and provisions of the
Credit Agreement. The parties hereto intend that, in addition to any other debt
or obligation secured hereby, this Deed of Trust shall secure unpaid balances of
loan advances made after this Deed of Trust is delivered to the Recorder for
recording, whether made pursuant to an obligation of the Beneficiary or
otherwise. Such loan advances are and will be evidenced by the Notes and may
fluctuate over time between zero and the maximum amount of $150,000,000. A
reduction in the amount of indebtedness to zero shall not affect the existence
or priority of the lien of this Deed of Trust.

                  THIS DEED OF TRUST includes the following covenants,
conditions and agreements:

                  FIRST: Grantor does hereby warrant that it has, and will have,
good and marketable rights, titles and interests in and to all the Property free
and clear of all liens and encumbrances except Permitted Liens, and that it will
generally warrant title to the Property and will defend the Property against the
claims and demands of all persons, corporations and any other entities
whatsoever; and Grantor does hereby covenant that it will promptly pay or cause
to be paid any and all other payments, and perform or cause to be performed any
and all other acts (including the delivery to the Beneficiary of such
agreements, instruments and documents as the Beneficiary deems necessary), so
that it will have good and marketable right, title and interest in and to all of
the Property free and clear of all liens and encumbrances other than Permitted
Liens and so that the liens and security interests created or granted hereby or
pursuant hereto are and shall continue to be valid and perfected first liens and
security interests.

                  SECOND: The Grantor will keep and perform, or cause to be kept
and performed, all the covenants and agreements in this Deed of Trust, in manner
and form as herein set out.

                  THIRD: The Grantor agrees to pay, or cause to be paid, when
due all taxes, charges, claims and assessments which may be assessed or levied
by any public authority against or upon the Property, and also any taxes,
charges, claims (including claims of mechanics and materialmen) or assessments
for which any present or future owner of the Property may be or become liable or
which may by law become a lien on the Property either having priority over the
indebtedness and other obligations secured hereby whether as to payment or
distribution on judicial sale, or (although not having priority) entitling any
governmental or taxing body to notice of foreclosure proceedings or to any right
of redemption thereafter, and also all other liabilities of any kind or nature
relating to the Property including without limitation all liabilities for labor,
services, materials, supplies and equipment incurred in or arising from the
development and operation of the Property, except that no such tax, charge,
claim, assessment or liability need be paid for so long as its validity or
amount shall be contested in good faith by appropriate proceedings duly
prosecuted and Grantor shall have set up in its books such reserves with respect
thereto as shall be dictated by sound accounting practices, provided, however,
that all such taxes, charges, claims, assessments and liabilities shall be paid,
subject to refund proceedings, if failure to pay would adversely affect the
rights or



                                      -5-
<PAGE>   86


titles of Grantor to any of the Property; and Grantor agrees to exhibit, or
cause to be exhibited, to the Beneficiary forthwith, upon request of the
Beneficiary, receipts or other evidence satisfactory to the Beneficiary, showing
the payment of all of such taxes, charges, claims, assessments and liabilities.

                  FOURTH: Grantor agrees that Grantor will not, without the
written consent of Beneficiary, sell, lease, transfer, mortgage, pledge, charge,
grant a lien upon or security interest in, or otherwise dispose of or encumber,
or permit any encumbrance to attach to, the Property or any part thereof, except
as otherwise permitted by the Credit Agreement. Grantor represents and warrants
that to the best of its knowledge after due inquiry, it has obtained, and agrees
that it will obtain, or shall cause to be obtained, all material permissions,
licenses, easements and rights-of-way and all local, state and federal
governmental approvals, authorizations, consents and permits as well as all
other rights, titles and interests reasonably necessary to the ownership and
operation of the Property, all of which are, and shall be kept, in full force
and effect. Grantor will operate, or cause to be operated, the Property in a
good and workmanlike manner on a continuous basis subject to, and in accordance
with, sound and approved business practices; will maintain, or cause to be
maintained, the Property in good repair, working order and condition, subject to
ordinary wear and tear; will not commit or permit any waste or impairment of the
Property; will not permit the Property to be used in violation of any statute or
regulation; will otherwise protect and preserve, or cause to be protected and
preserved, the Property; and upon reasonable prior notice, will permit
Beneficiary and its representatives and agents, or cause them to be permitted,
to inspect the Property during normal business hours.

                  FIFTH: Grantor will keep, or cause to be kept, with
financially sound and reputable insurers, such insurance with respect to the
Property, in such amounts and insuring against such risks, casualties and
contingencies of such types (including but not limited to insurance for loss or
damage by fire and other hazards and insurance for liability for damage to
persons and property in connection with the Property and the activities
conducted thereon or relating thereto) as is customary for persons, corporations
and other entities of established reputations engaged in the same or similar
businesses as the Grantor and similarly situated, naming Beneficiary as
mortgagee or lender loss payee or additional insured as its interests may
appear, and will keep, or cause to be kept, such insurance as required by any
applicable workmen's compensation laws. If no Default or Event of Default under
the Credit Agreement exists, and if the Beneficiary determines in its reasonable
discretion that the Property can be satisfactorily repaired or restored, then
the insurance proceeds shall be applied to repair or restore the Property under
such terms and conditions as the Beneficiary may impose. The Beneficiary shall
not be deemed to have elected any option made available pursuant to this
Paragraph Fifth until such option is elected specifically in writing. Until so
elected, the Beneficiary shall not in any circumstances be deemed to have waived
its right to make such election. Upon an occurrence of a Default or an Event of
Default under the Credit Agreement all proceeds of insurance for loss or damage
to the Property shall be paid to the Beneficiary and shall be applied to the
payment of the indebtedness and other obligations secured hereby in such manner
and order as the Beneficiary may elect. All policies shall provide that they may
cancelled except on thirty (30) days' prior written notice to the Beneficiary.

                  SIXTH: If Grantor shall fail to pay or cause to be paid the
premiums on the policies for the above described insurance when due, or shall
fail to pay or cause to be paid all payments or to perform or cause to be
performed all acts so that the liens and security interests created or granted
hereby or pursuant hereto are valid and perfected first priority liens and



                                      -6-
<PAGE>   87


security interests in full force and effect or shall fail to pay or cause to be
paid when due any taxes, charges, claims, assessments or liabilities hereinabove
agreed to be paid or caused to be paid by the Grantor, or shall fail to obtain
and keep in full force and effect, or cause to be obtained and kept in full
force and effect, all rights, titles and interests necessary to the ownership,
development and operation of the Property, then the Beneficiary may at its
option do so and the amount and cost thereof shall be added to the balance of
the debts secured hereby, shall be payable on demand and shall bear interest at
the highest rate shown in the then outstanding Notes until paid.

                  SEVENTH: The Grantor represents and warrants that to the best
of its knowledge (i) the Property is and has been in compliance, in all material
respects, with all applicable local, state and federal environmental laws, rules
and regulations and (ii) there have been no material releases of any chemical,
material, substance or waste which is a threat to the public health, safety or
welfare or the environment or the health of living organisms, or any hazardous,
toxic, contaminating or polluting substance as defined by any environmental law,
rule or regulation (individually and collectively "HAZARDOUS SUBSTANCES").

                  Grantor will ensure that the Property remains in compliance,
in all material respects, with all local, state and federal environmental laws,
rules and regulations, and that it will not place or permit to be placed on the
Property any Hazardous Substances, except as not prohibited by applicable
environmental laws, rules or regulations, or in such quantities as to not
constitute a hazard to the environment or subject the Grantor to prosecution or
liability in connection therewith.

                  Grantor will employ in connection with its use of the Property
appropriate technology as the Grantor determines reasonably necessary to
maintain compliance in all material respects with any applicable environmental
law, rule or regulation and dispose of any and all Hazardous Substances
generated at the Property only at facilities and with carriers that maintain
valid permits under applicable environmental laws, rules and regulations.

                  In the event the Grantor obtains, gives or receives notice of
any release or threat of release of a reportable quantity of any Hazardous
Substances at the Property or receives any notice of violation, request for
information or notification that it is potentially responsible for investigation
or cleanup of environmental conditions at the Property, or any demand letter,
complaint, order, citation or other written notice with regard to any Hazardous
Substances or violation of any environmental law, rule or regulation, affecting
the Property from any person or entity, including any state agency responsible
in whole or in part for environmental matters in the state in which the Property
is located or the United States Environmental Protection Agency (any such person
or entity is hereinafter referred to as the "AUTHORITY"), then the Grantor
shall, within five (5) days, give written notice of the same to the Beneficiary
detailing facts and circumstances of which the Grantor is aware in connection
therewith. Such information is to be provided to allow Beneficiary to protect
its security interest in the Property and is not intended to create any
obligation upon the Beneficiary with respect thereto.

                  Grantor shall promptly forward to the Beneficiary copies of
any request for information, notification of material potential liability,
demand letter for information, notification of material potential liability,
demand letter relating to material potential responsibility with respect to the
investigation or cleanup of Hazardous Substances at the Property and shall
continue to forward to the Beneficiary copies of material correspondence between
the Grantor and the Authority regarding such claims until the claims are
settled. The Grantor shall promptly forward



                                      -7-
<PAGE>   88


to the Beneficiary copies of all documents and reports concerning Hazardous
Substances at the Property that the Grantor is required to file under any
environmental law, rule or regulation. Such information is to be provided to
allow the Beneficiary to protect its security interest in the Property and is
not intended to create any obligation upon the Beneficiary with respect thereto.

                  If the Grantor shall fail to comply with any of the material
requirements of any environmental law, rule or regulation, the Beneficiary may,
at its election, but without the obligation to do so, for the sole purpose of
protecting its security interest in the Property, enter onto the Property (or
authorize third parties to enter onto the Property) and take such actions as the
Beneficiary (or such third parties as directed by the Beneficiary) deems
reasonably necessary or advisable, after consultation with the Grantor, to
comply with the requirements of such environmental laws, rules and regulations
including but not limited to cleaning up, removing, mitigating or otherwise
dealing with any release of Hazardous Substances. All reasonable costs and
expenses incurred by the Beneficiary (or such third parties) in the exercise of
any such rights, including any sums paid in connection with any judicial or
administrative investigation or proceedings, fines and penalties, together with
interest thereon from the date expended at the highest rate set forth in the
then outstanding Notes, shall be paid upon demand by the Grantor, and until paid
shall be added to and become a part of the indebtedness secured hereby.

                  Grantor shall defend and indemnify the Beneficiary and hold
the Beneficiary harmless from and against all loss, liability, damage and
expense, claims, costs, fines and penalties, including reasonable attorney's
fees, suffered or incurred by the Beneficiary, whether as a mortgagee in
possession, or as successor-in-interest to the Grantor, or otherwise, under or
on account of any environmental law, rule or regulation, including the assertion
of any lien thereunder, with respect to any release of Hazardous Substances, the
presence of any Hazardous Substances affecting the Property, whether or not the
same originates or emanates from the Property or any contiguous real estate,
including any loss of value of the Property as a result of the foregoing so long
as no such loss, liability, damage and expense is attributable to any release of
Hazardous Substances resulting from actions on the part of the Beneficiary. The
Grantor's obligations under this paragraph Seventh shall arise upon the
discovery of the presence of any Hazardous Substances at the Property, whether
or not any Authority has taken or threatened any action in connection with the
presence of any Hazardous Substances. The Grantor's obligation and the
indemnification hereunder shall survive foreclosure or other exercise by
Beneficiary of any remedy hereunder and the payment in full of the indebtedness
secured hereby and the satisfaction in full of the other obligations secured
hereby.

                  EIGHTH: Grantor agrees to pay or cause to be paid all costs of
recording, filing, continuing, satisfying or terminating any documents or
instruments executed in connection with or securing the obligations and debts
secured hereby including this Deed of Trust and such financing statements as the
Beneficiary shall deem reasonably necessary such as but not limited to any
documentary or stamp tax or other recordation tax or charge which may at any
time be imposed. Upon the occurrence of an Event of Default under the Credit
Agreement, Grantor hereby makes, constitutes and appoints the Beneficiary the
true and lawful agent and attorney-in-fact of Grantor, with full power of
substitution, to do any and all things and take any and all action, in the name
and on behalf of Grantor, which the Beneficiary may deem necessary or advisable
to carry out the intent of this Deed of Trust, including, without limitation,
the grant of the liens and security interests created hereby and the perfection,
continuation and protection of the liens and security interests created hereby
and the exercise by Beneficiary of the rights created under this Deed of Trust,
such as signing the name of Grantor to financing



                                      -8-
<PAGE>   89


statements and all amendments and modifications thereof and supplements thereto.
Grantor agrees that neither the Beneficiary nor any of its agents, designees or
attorneys-in-fact will be liable for any acts of commission or omission, or for
any error of judgment or mistake of fact or law with respect to the exercise of
the power of attorney granted under this paragraph. The power of attorney
granted under this paragraph is coupled with an interest and shall be
irrevocable until all indebtedness secured hereby is paid in full and all other
obligations secured hereby are fully performed. Any costs or fees paid by
Beneficiary and/or the Trustee in connection therewith shall be added to the
balance of the debts secured hereby, shall be payable on demand and shall bear
interest at the highest rate shown in the then outstanding Notes until paid.

                  NINTH: Grantor agrees to promptly pay or cause to be paid all
sums, including costs, expenses and reasonable attorneys' fees, which the
Beneficiary and/or the Trustee may incur or expend in connection with or
relating to any proceeding to sustain the liens and security interests of this
Deed of Trust, or their priority, or in defending against the liens, security
interests or claims of any person, corporation or other entity asserting
priority over this Deed of Trust, and all such sums to be paid to the
Beneficiary and/or the Trustee shall be added to the balance of the indebtedness
secured hereby, shall be payable on demand and shall bear interest at the
highest rate shown in the then outstanding Notes until paid.

                  TENTH: Upon the occurrence of an Event of Default under the
Credit Agreement, Grantor does further agree to execute and deliver, or cause to
be executed and delivered, any and all transfer orders, division orders and
other documents and instruments that may be reasonably requested by Beneficiary
for the purpose of implementing this Deed of Trust.

                  ELEVENTH: Grantor agrees that it will upon the request of
Beneficiary furnish, or cause to be furnished, to Beneficiary copies of invoices
issued by Grantor in connection with the subject matter of this Deed of Trust,
and will make available to Beneficiary, at any time and from time to time, on
its reasonable request, any and all of Grantor's books, records, written
memoranda, correspondence, shipping orders and any other instruments or writings
in any way evidencing or relating to the subject matter hereof, and will also
upon reasonable request, and at its own expense, furnish, or cause to be
furnished, such witnesses as may be required to make legal proof thereof. Any
and all records relating to the Property in the possession of, or subject to the
control of, Grantor will be kept at Grantor's office at the address shown on the
first page hereof, and the Grantor will not remove, nor permit the removal of,
such records from such location without the prior written consent of the
Beneficiary.

                  TWELFTH: Beneficiary and its successors and assigns are hereby
absolved from all liability of any kind whatsoever for failure for any reason to
enforce collection of any proceeds, accounts, accounts receivable, contract
rights or other rights, titles and interests which are subject to this Deed of
Trust and from all other responsibility in connection therewith, except the
responsibility to account to the Grantor for funds actually received.

                  THIRTEENTH: It is expressly covenanted and agreed by Grantor
that upon the occurrence of an Event of Default under the Credit Agreement, then
Beneficiary may at any time and from time to time declare any or all of the
secured indebtedness immediately due and payable and such secured indebtedness
shall thereupon be immediately due and payable, without presentment, demand,
protest notice of protest, notice of acceleration or of intention to



                                      -9-
<PAGE>   90


accelerate or any other notice or declaration of any kind, all of which are
hereby expressly waived by Grantor.

                  FOURTEENTH: It is expressly covenanted and agreed by Grantor
that after the occurrence of an Event of Default under the Credit Agreement,
then Trustee, or his successor or substitute, is authorized and empowered and it
shall be his special duty at the request of Beneficiary to sell the Property or
any part thereof situated in the State of Texas, at the courthouse of any county
(whether or not the counties in which the Property is located are contiguous, if
the Property is located in more than one county) in the State of Texas in which
any part of the Property is situated, at public venue to the highest bidder for
cash between the hours of ten o'clock a.m. and four o'clock p.m. on the first
Tuesday in any month or at such other place, time and date as provided by the
statutes of the State of Texas then in force governing sales of real estate
under powers of sale conferred by deed of trust, after having given notice of
such sale in accordance with such statutes. Any sale made by Trustee hereunder
may be as an entirety or in such parcels as Beneficiary may request. To the
extent by applicable law, any sale may be adjourned by announcement at the time
and place appointed for such sale without further notice except as may be
required by law. The sale by Trustee of less than the whole of the Property
shall not exhaust the power of sale herein granted, and Trustee is specifically
empowered to make successive sale or sales under such power until the whole of
the Property shall be sold; and, if the proceeds of such sale of less than the
whole of the Property shall be less than the aggregate of the indebtedness
secured hereby and the expense of executing this trust as provided herein, this
Deed of Trust and the lien hereof shall remain in force and effect as to the
unsold portion of the Property just as though no sale had been made; provided,
however, that Grantor shall never have any right to require the sale of less
than the whole of the Property but Beneficiary shall have the right at its sole
election, to request Trustee to sell less than the whole of the Property.
Trustee may, after any request or direction by Beneficiary, sell not only the
real property but also the personal property and other interests which are a
part of the Property, or any part thereof, as a unit and as a part of 'a single
sale, or may sell any part of the Property separately from the remainder of the
Property. It shall not be necessary for Trustee to have taken possession of any
part of the Property or to have present or to exhibit at any sale any of the
personal property. After each sale, Trustee shall make to the purchaser or
purchasers at such sale good and sufficient conveyances in the name of Grantor,
conveying the property so sold to the purchaser or purchasers with general
warranty of title by Grantor, subject to the Permitted Liens (and to such leases
and other matters, if any, as Trustee may elect upon request of Beneficiary),
and shall receive the proceeds of said sale or sales and apply the same as
herein provided. Payment of the purchase price to the Trustee shall satisfy the
obligation of purchaser at such sale therefor, and such purchaser shall not be
responsible for the application thereof. The power of sale granted herein shall
not be exhausted by any sale held hereunder by Trustee or his substitute or
successor, and such power of sale may be exercised from time to time and as many
times as Beneficiary may deem necessary until all of the Property has been duty'
sold and all secured indebtedness has been fully paid. In the event any sale
hereunder is not completed or is defective in the opinion of Beneficiary, such
sale shall not exhaust the power of sale hereunder and Beneficiary shall have
the right to cause a subsequent sale or sales to be made hereunder. Any and all
statements of fact or other recitals made in any deed or deeds or other
conveyances given by Trustee or any successor or substitute appointed hereunder
as to nonpayment of the secured indebtedness or as to the occurrence of any
default, or as to Beneficiary's having declared all of said indebtedness to be
due and payable, or as to the request to sell, or as to notice of time, place
and terms of sale and the properties to be sold having been duly given, or as to
the refusal, failure or inability to act of Trustee or any substitute or
successor trustee, or as to the appointment of any substitute



                                      -10-
<PAGE>   91


or successor trustee, or as to any other act or thing having been duly done by
Beneficiary or by such Trustee, substitute or successor, shall be taken as prima
facie evidence of the truth of the facts so stated and recited. The Trustee or
his successor or substitute may appoint or delegate any one or more persons as
agent to perform any act or acts necessary or incident to any sale held by
Trustee, including the posting of notices and the conduct of sale, but in the
name and on behalf of Trustee, his successor or substitute. If Trustee or his
successor or substitute shall have given notice of sale hereunder, any successor
or substitute Trustee thereafter appointed may complete the sale and the
conveyance of the property pursuant thereto as if such notice had been given by
the successor or substitute Trustee conducting the sale.

                  FIFTEENTH: Without limitation of Beneficiary's rights of
enforcement with respect to any portion of the Property which constitute
personal property under the Uniform Commercial Code or any part thereof in
accordance with the procedures for foreclosure of real estate, Beneficiary may
exercise its rights of enforcement with respect to such personal property or any
part thereof under the Uniform Commercial Code and in conjunction with, in
addition to or in substitution for those rights and remedies; (1) Beneficiary
may enter upon Grantor's premises to take possession of, assemble and collect
the personal property or, to the extent and for those items of the personal
property permitted under applicable law, to render it unusable; (2) Beneficiary
may require Grantor to assemble the personal property and make it available at a
place Beneficiary designates which is mutually convenient to allow Beneficiary
to take possession or dispose of the personal property; (3) written notice
mailed to Grantor as provided herein at least ten (10) days prior to the date of
public sale of the personal property or prior to the date after which private
sale of the personal property will be made shall constitute reasonable notice;
(4) in the event of a foreclosure sale, whether made by Trustee under the terms
hereof, or under judgment of a court, the personal property and the other
Property may, at the option of Beneficiary, be sold as a whole; (5) it shall not
be necessary that Beneficiary take possession of the personal property or any
part thereof prior to the time that any sale pursuant to the provisions of this
Section is conducted and it shall not be necessary that the personal property or
any part thereof be present at the location of such sale; (1) with respect to
application of proceeds of disposition of the personal property pledged
hereunder, the costs and expenses incident to disposition shall include the
reasonable expenses of retaking, holding, preparing for sale or lease, selling,
leasing and the reasonable attorneys' fees and legal expenses incurred by
Beneficiary; (6) any and all statements of fact or other recitals made in any
bill of sale or assignment or other instrument evidencing any foreclosure sale
hereunder as to nonpayment of the secured indebtedness or as to the occurrence
of any default, or as to Beneficiary having declared all of such indebtedness to
be due and payable, or as to notice of time, place and terms of sale and of the
properties to be sold having been duly given, or as to any other act or thing
having been duly done by Beneficiary, shall be taken as prima facie evidence of
the truth of the facts so stated and recited; and (7) Beneficiary may appoint or
delegate any one or more persons as agent to perform any act or acts necessary
or incident to any sale held by Beneficiary, including the sending of notices
and the conduct of the sale, but in the name and on behalf of Beneficiary.

                  SIXTEENTH: It is expressly covenanted and agreed by Grantor
that in the event that Grantor fails to pay when due, whether by acceleration or
otherwise, the Lender Obligations pursuant to the terms of the Subsidiary
Guaranty or fails to pay when due any other indebtedness secured hereby, or if
Grantor fails to perform, or cause to be performed, any of the other obligations
of the Subsidiary Guaranty, this Deed of Trust, the Subsidiary Security
Agreements or other document or instrument secured hereby or providing security
for the



                                      -11-
<PAGE>   92


indebtedness or other obligations secured hereby, then Beneficiary may proceed
by a suit or suits in equity or at law, whether for collection of the
indebtedness secured hereby, the specific performance of any covenant or
agreement herein contained or in aid of the execution of any power herein
granted, or for any foreclosure hereunder or for the sale of the Property under
the judgment or decree of any court or courts of competent jurisdiction.

                  SEVENTEENTH: It is expressly covenanted and agreed by Grantor
that in the event that Grantor fails to pay when due, whether by acceleration or
otherwise, the Lender Obligations pursuant to the terms of the Subsidiary
Guaranty or fails to pay when due any other indebtedness secured hereby, or if
Grantor fails to perform, or cause to be performed, any of the other obligations
of the Subsidiary Guaranty, this Deed of Trust, the Subsidiary Security
Agreement or other document or instrument secured hereby or providing security
for the indebtedness or other obligations secured hereby, then Beneficiary is
authorized, prior or subsequent to the institution of any foreclosure
proceedings, to the fullest extent permitted by applicable law, to enter upon
the Property, or any part thereof, and to take possession of the Property and
all books and records relating thereto, and to exercise without interference
from Grantor any and all rights which Grantor has with respect to the
management, possession, operation, protection or preservation of the Property.
Beneficiary shall not be deemed to have taken possession of the Property or any
part thereof except upon the exercise of its right to do so, and then only to
the extent evidenced by its demand and overt act specifically for such purpose.
All costs, expenses and liabilities of every character incurred by Beneficiary
in managing, operating, maintaining, protecting or preserving the Property shall
constitute a demand obligation of Grantor (which obligation Grantor hereby
promises to pay) to Beneficiary pursuant to this Deed of Trust If necessary to
obtain the possession provided for above, Beneficiary may invoke any and all
legal remedies to dispossess Grantor. In connection with any action taken by
Beneficiary pursuant to this Section, Beneficiary shall not be liable for any
loss sustained by Grantor resulting from any failure to let the Property or any
part thereof, or from any act or omission of Beneficiary in managing the
Property unless such loss is caused by the willful misconduct, gross negligence
and bad faith of Beneficiary, nor shall Beneficiary be obligated to perform or
discharge any obligation, duty or liability of Grantor arising under any lease
or other agreement relating to the Property or arising under any Permitted
Encumbrance or otherwise arising. Grantor hereby assents to, ratifies and
confirms any and all actions of Beneficiary with respect to the Property taken
under this Section.

                  EIGHTEENTH: It is expressly covenanted and agreed by Grantor
that in the event that Grantor fails to pay when due, whether by acceleration or
otherwise, the Lender Obligations pursuant to the terms to the terms of the
Subsidiary Guaranty or fails to pay when due any other indebtedness secured
hereby, or if Grantor fails to perform, or cause to be performed, any of the
other obligations of the Subsidiary Guaranty, this Deed of Trust, the Subsidiary
Security Agreement or other document or instrument secured hereby or providing
security for the indebtedness or other obligations secured hereby, then
Beneficiary shall as a matter of right be entitled to the appointment of a
receiver or receivers for all or any part of the Property, whether such
receivership be incident to a proposed sale (or sales) of such property or
otherwise, and without regard to the value of the Property or the solvency of
any person or persons liable for the payment of the indebtedness secured hereby,
and Grantor does hereby irrevocably consent to the appointment of such receiver
or receivers, waives any and all defenses to such appointment, agrees not to
oppose any application therefor by Beneficiary, and agrees that such appointment
shall in no manner impair, prejudice or otherwise affect the rights of
Beneficiary to application of Rents as provided in this Deed of Trust. Nothing
herein is to be construed to deprive Beneficiary of any other right, remedy or
privilege it may have under



                                      -12-
<PAGE>   93


the law to have a receiver appointed. Any money advanced by Beneficiary in
connection with any such receivership shall be a demand obligation (which
obligation Grantor hereby promises to pay) owing by Grantor to Beneficiary
pursuant to this Deed of Trust.

                  NINETEENTH: Beneficiary may exercise any and all other rights
and remedies which Beneficiary may have under the Subsidiary Guaranty, the
Subsidiary Security Agreement or any other document executed in connection
therewith, or at law or in equity or otherwise. In the event that Beneficiary
exercises its rights to commence foreclosure proceedings or to take possession
and control of all or any part of the Property, the Trustee, Beneficiary and/or
any person or entity designated by Beneficiary may operate and maintain the
Property at the expense of Grantor and without any liability to Grantor in
connection with such operations; and the Beneficiary, Trustee and/or any person
or entity designated by Beneficiary will have the right, but not the obligation,
to make repairs, to purchase machinery and equipment and to conduct workover
operations, and in connection therewith, to exercise every power, right and
privilege of Grantor with respect to the Property and after deducting the
expenses of developing, operating and maintaining the Property (including but
not limited to the costs of repairs and improvements, insurance premiums and tax
assessments and other charges on the Property as well as reasonable compensation
for the services of Trustee or other designated parties), the Beneficiary shall
apply the proceeds received from the operation of the Property to the payment of
the indebtedness and obligations secured hereby, in such manner and in such
order as Beneficiary may elect.

                  TWENTIETH: This instrument shall be effective as a mortgage as
well as a deed of trust and upon the occurrence of a default may be foreclosed
as to any of the Property in any manner permitted by applicable law, and any
foreclosure suit may be brought by Trustee or by Beneficiary; and to the extent,
if any, required to cause this instrument to be so effective as a mortgage as
well as a deed of trust, Grantor hereby mortgages the Property to Beneficiary.
In the event a foreclosure hereunder shall be commenced by Trustee, or his
substitute or successor, Beneficiary may at any time before the sale of the
Property direct Trustee to abandon the sale, and may then institute suit for the
collection of the Subsidiary Guaranty and/or any other secured indebtedness, and
for the foreclosure of this Deed of Trust. It is agreed that if Beneficiary
should institute a suit for the collection of the Subsidiary Guaranty or any
other secured indebtedness and for the foreclosure of this Deed of Trust,
Beneficiary may at any time before the entry of a final judgment in said suit
dismiss the same, and require Trustee, his substitute or successor to sell the
Property in accordance with the provisions of this Deed of Trust.

                  TWENTY-FIRST: The proceeds of any sale held by Trustee or
Beneficiary or any receiver or public officer in foreclosure of the liens and
security interests evidenced hereby shall be applied: first, to the payment of
all necessary costs and expenses incident to such foreclosure sale, including
but not limited to all reasonable attorneys' fees and legal expenses, all court
costs and charges of every character and a reasonable fee to Trustee if
foreclosed by power of sale as provided herein, and to the payment of the other
secured indebtedness, including specifically without limitation the principal,
accrued interest and attorneys' fees due and unpaid on the Notes and the amounts
due and unpaid and owed to Beneficiary under this Deed of Trust the order and
manner of application to the items in this clause first to be in Beneficiary's
sole discretion; and second, the remainder, if any there shall be, shall be paid
to Grantor, or to Grantor's heirs, devisees, representatives, successors or
assigns, or such other persons (including the Beneficiary or beneficiary of any
inferior lien) as may be entitled thereto by law; provided, however, that if
Beneficiary is uncertain which person or persons are so



                                      -13-
<PAGE>   94


entitled, Beneficiary may interplead such remainder in any court of competent
jurisdiction, and the amount of any attorneys' fees, court costs and expenses
incurred in such action shall be a part of the secured indebtedness and shall be
reimbursable (without limitation) from such remainder.

                  TWENTY-SECOND: Beneficiary shall have the right to become the
purchaser at any sale held by Trustee or substitute or successor or by any
receiver or public officer or at any public sale, and Beneficiary shall have the
right to credit upon the amount of Beneficiary's successful bid, to the extent
necessary to satisfy such bid, all or any part of the indebtedness secured
hereby in such manner and order as Beneficiary may elect.

                  TWENTY-THIRD: It is expressly covenanted and agreed by Grantor
that in the event that Grantor fails to pay when due, whether by acceleration or
otherwise, any principal or interest pursuant to the terms of the Notes or fails
to pay when due any other indebtedness secured hereby, or if Grantor fails to
perform, or cause to be performed, any of the other obligations of the
Subsidiary Guaranty, this Deed of Trust, the Subsidiary Security Agreement or
other document or instrument secured hereby or providing security for the
indebtedness or other obligations secured hereby, then, Beneficiary shall have
the right to proceed with foreclosure (judicial or nonjudicial) of the liens and
security interests hereunder without declaring the entire secured indebtedness
due, and in such event any such foreclosure sale may be made subject to the
unmatured part of the secured indebtedness; and any such sale shall not in any
manner affect the unmatured part of the secured indebtedness, but as to such
unmatured part this Deed of Trust shall remain in full force and effect just as
though no sale had been made. The proceeds of such sale shall be applied as
provided in paragraph Twenty-First hereof except that the amount paid under
clause first thereof shall be only the matured portion of the secured
indebtedness and any proceeds of such sale in excess of those provided for in
clause first (modified as provided above) shall be applied to the prepayment
(without penalty) of any other secured indebtedness in such manner and order and
to such extent as Beneficiary deems advisable, and the remainder, if any, shall
be applied as provided in clause second of paragraph Twenty-First hereof.
Several sales may be made hereunder without exhausting the right of sale for any
unmatured part of the secured indebtedness.

                  TWENTY-FOURTH: All rights and remedies provided for herein, in
the Credit Agreement, the Subsidiary Guaranty or in any other document executed
in connection herewith or therewith are cumulative of each other and of any and
all other rights and remedies existing at law or in equity, and Trustee and
Beneficiary shall, in addition to the rights and remedies provided herein or in
any other document be entitled to avail themselves of all such other rights and
remedies as may now or hereafter exist at law or in equity for the collection of
the secured indebtedness and the enforcement of the covenants herein and the
foreclosure of the liens and security interests evidenced hereby, and the resort
to any right or remedy provided for hereunder or under any such other document
or provided for by law or in equity shall not prevent the concurrent or
subsequent employment of any other appropriate right or rights or remedy or
remedies.

                  TWENTY-FIFTH: In the event there is a foreclosure sale
hereunder and at the time of such sale, Grantor or Grantor's successors or
assigns are occupying or using the Property, or any part thereof, each and all
shall immediately become the tenant of the purchaser at such sale, which tenancy
shall be a tenancy from day to day, terminable at the will of either landlord or
tenant, at a reasonable rental per day based upon the value of the property
occupied, such rental to be due daily to the purchaser; and to the extent
permitted by applicable



                                      -14-
<PAGE>   95


law, the purchaser at such sale shall, notwithstanding any language herein
apparently to the contrary, have the sole option to demand immediate possession
following the sale or to permit the occupants to remain as tenants at will. In
the event the tenant fails to surrender possession of said property upon demand,
the purchaser shall be entitled to institute and maintain a summary action for
possession of the property (such as an action for forcible detainer) in any
court having jurisdiction.

                  TWENTY-SIXTH: To the full extent Grantor may do so, Grantor
agrees that Grantor will not at any time insist upon, plead, claim or take the
benefit or advantage of any law now or hereafter in force providing for any
appraisement valuation, stay, extension or redemption, and Grantor, for Grantor,
Grantor's successors and assigns, and for any and all persons ever claiming any
interest in the Property, to the extent permitted by applicable law, hereby
waives and releases all rights of redemption, valuation, appraisement, stay of
execution, notice of intention to mature or declare due the whole of the secured
indebtedness, and all rights to a marshaling of assets of Grantor, including the
Property, or to a sale in inverse order of alienation in the event of
foreclosure of the liens and/or security interests hereby created, except for
Grantor's rights under Sections 5 1.003-51.005 of the Texas Property Code, as
amended or replaced. Grantor shall not have or assert any right under any
statute or rule of law pertaining to the marshaling of assets, sale in inverse
order of alienation, the exemption of homestead, the administration of estates
of decedents, or other matters whatever to defeat, reduce or affect the right of
Beneficiary under the terms of this Deed of Trust to a sale of the Property for
the collection of the secured indebtedness without any prior or different resort
for collection, or the right of Beneficiary under the terms of this Deed of
Trust to the payment of the secured indebtedness out of the proceeds of sale of
the Property in preference to every other claimant whatever. Grantor waives any
right or remedy which Grantor may have or be able to assert pursuant to any
provision of any law pertaining to the rights and remedies of sureties. If any
law referred to in this Section and now in force, of which Grantor or Grantor's
heirs, devises, representatives, successors or assigns or any other persons
claiming any interest in the Property might take advantage despite this Section,
shall hereafter be repealed or ceases to be in force, such law shall not
thereafter be deemed to preclude the application of this Section.

                  TWENTY-SEVENTH: Except as set forth herein, the Trustee shall
serve without compensation; provided, however, the Grantor covenants and agrees
to pay to the Trustee, on demand, all costs and expenses reasonably made or
incurred in and about the execution of the trust created hereby. The Grantor
covenants and agrees to indemnify the Trustee against any and all liabilities or
losses which he may incur hereunder not due to his own gross negligence or
willful misconduct. All monies and other property and proceeds of property
received by the Trustee at any time in the exercise of the trust created hereby
shall be held in trust for the Beneficiary. The Trustee is hereby empowered to
do, and perform, any act or duty in and under this Deed of Trust by and through
an agent or attorney. The Beneficiary hereby reserves, and shall have, the
absolute and unconditioned right and privilege to be exercised at any time and
from time to time to remove the Trustee (or any successor Trustee) by
appointing, by an instrument in writing, another trustee in the place and stead
of the Trustee (or any successor Trustee), which trustee shall have all the
rights, powers and authority and be charged with all the duties that are
conferred or charged upon the Trustee.

                  TWENTY-EIGHTH: The Trustee and/or the Beneficiary may have or
in the future may hold other security and/or guaranties to secure all or any
part of the indebtedness and other obligations secured hereby, but it is
specifically understood and agreed that neither



                                      -15-
<PAGE>   96


the execution and delivery of this Deed of Trust nor the holding of any other
security and/or guaranty shall at any time or in any wise operate to prevent or
hinder the Trustee and/or the Beneficiary from resorting first to such other
security and/or guaranty or first to the Property, or first from time to time to
both; and the Trustee and/or the Beneficiary may from time to time as the
Beneficiary sees fit, in the Beneficiary's sole and uncontrolled discretion,
resort to all or any part of the Property without resorting to all or any other
security and/or guaranty securing such indebtedness and other obligations, or to
all or any part of any other security and/or guaranty securing such indebtedness
and other obligations without resorting to all or any part of the Property, and
such action on the Trustee's and/or the Beneficiary's part shall not in any wise
be considered as a waiver of any of the benefits or rights of the Trustee and/or
the Beneficiary relating to the Property or such other security and/or
guaranties.

                  TWENTY-NINTH: A copy of any notice of trustee's sale under
this Deed of Trust shall be served on Grantor by certified mail, return receipt
requested, directed to Grantor at its address stated below or such other address
given to Beneficiary in writing by Grantor subsequent to the execution and
delivery of this Deed of Trust and shall be effective when deposited, postage
prepaid, in the United States mail. Any other notice shall be effective upon the
deposit of such notice, in writing, in the regular United States mail, postage
prepaid, addressed to such party or parties to receive notice at the following
addresses or at such other address as any such party may given to the other
parties in writing:

                  To Grantor:

                           Seadrift Coke, L.P.
                           c/o The Carbide/Graphite Group, Inc.

                           Pittsburgh, Pennsylvania 15222
                           Attention: Vice President Finance

                  To Beneficiary:

                           Pittsburgh, Pennsylvania 15222
                           Attention: Agency Services

                  To Trustee:

                           Mark W. Rutherford
                           One PNC Plaza, 3rd Floor

                           Pittsburgh, Pennsylvania  15222

                  THIRTIETH: No waiver by the Beneficiary or the Trustee of any
default shall operate as a waiver of any other default or of the same default on
a future occasion. No failure or delay on the part of the Beneficiary or the
Trustee in the exercise of any right or remedy shall operate as a waiver
thereof, nor shall any single or partial exercise of any right or remedy
preclude other or further exercise thereof, or the exercise of any other right
or remedy.


                                      -16-
<PAGE>   97


                  THIRTY-FIRST: Neither this Deed of Trust nor any term hereof
may be changed, waived, discharged or terminated orally, or by any action or
inaction, but only by an instrument in writing signed by the party against which
enforcement of the change, waiver, discharge or termination is sought. The
modification hereof or of the Credit Agreement, the Subsidiary Guaranty, the
Subsidiary Security Agreement or any other instrument or document secured hereby
or securing the indebtedness and other obligations secured hereby shall not
impair the priority of the liens and security interests created or granted
hereby or pursuant hereto; and the release of any part of the Property from the
liens and security interests created or granted hereby or pursuant hereto shall
not impair the priority of the liens and security interests created or granted
hereby or pursuant hereto with respect to the part of the Property not so
released. Nothing contained in this Deed of Trust is intended to alter or affect
the provisions of any partial release or subordination agreement of record
heretofore executed by the Beneficiary with respect to any of the Property.

                  THIRTY-SECOND: In the event that any covenant, condition or
agreement of this Deed of Trust is lawfully held or declared to be invalid,
illegal or unenforceable, it shall be deemed deleted to the extent necessary
under the applicable law and the validity of the other covenants, conditions and
agreements shall not be affected thereby.

                  THIRTY-THIRD: The covenants, conditions and agreements
contained in this Deed of Trust shall bind, and the benefits thereof shall inure
to, the successors and assigns of the Grantor, the successors and assigns of the
Trustee and the successors and assigns of the Beneficiary.

                  THIRTY-FOURTH: THIS DEED OF TRUST SHALL BE GOVERNED BY AND
CONSTRUED AND ENFORCED ACCORDING TO THE LAWS (WITHOUT GIVING EFFECT TO THE
CONFLICT OF LAW PRINCIPLES THEREOF) OF THE COMMONWEALTH OF PENNSYLVANIA EXCEPT
THAT (a) PURSUANT TO THE PROVISIONS OF SECTION 9.103 OF THE UNIFORM COMMERCIAL
CODE AS IN FORCE IN THE COMMONWEALTH OF PENNSYLVANIA, AS IT MAYBE AMENDED FROM
TIME TO TIME, THE LAWS OF THE STATE OF TEXAS MAY GOVERN THE PERFECTION AND
EFFECT OF PERFECTION OR NON-PERFECTION OF SECURITY INTERESTS IN CERTAIN OF THE
PROPERTY AND (b) THE LAWS OF THE STATE OF TEXAS WILL GOVERN WHETHER A
TRANSACTION TRANSFERS OR CREATES AN INTEREST IN REAL PROPERTY WITHIN THE STATE
OF TEXAS FOR SECURITY PURPOSES OR OTHERWISE, THE NATURE OF AN INTEREST IN REAL
PROPERTY WITHIN THE STATE OF TEXAS THAT IS TRANSFERRED OR CREATED BY A
TRANSACTION, THE METHOD FOR FORECLOSURE OF A LIEN ON REAL PROPERTY WITHIN THE
STATE OF TEXAS, THE NATURE OF AN INTEREST IN REAL PROPERTY WITHIN THE STATE OF
TEXAS THAT RESULTS FROM FORECLOSURE, OR THE MANNER AND EFFECT OF RECORDING OR
FAILING TO RECORD EVIDENCE OF A TRANSACTION THAT TRANSFERS OR CREATES AN
INTEREST IN REAL PROPERTY WITHIN THE STATE OF TEXAS. WHENEVER REFERENCE IS MADE
TO THE LOAN AGREEMENT OR OTHER LOAN DOCUMENTS, THOSE INSTRUMENTS SHALL BE DEEMED
TO BE GOVERNED BY AND CONSTRUED ACCORDING TO THE INTERNAL LAWS OF THE
COMMONWEALTH OF PENNSYLVANIA, AS EACH SUCH INSTRUMENT SO PROVIDES.

                  THIRTY-FIFTH: Whenever required by the context of this Deed of
