                   PDG ENVIRONMENTAL, INC. AND SUBSIDIARIES
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
             FOR THE THREE AND NINE MONTHS ENDED OCTOBER 31, 1995
                                 (UNAUDITED)

NOTE 1 - BASIS OF PRESENTATION

The consolidated financial statements include PDG Environmental, Inc.'s
wholly-owned subsidiaries and the accounts of PDG Remediation, Inc.  ("PDGR"),
in which PDG Environmental, Inc. maintains a 59.5% ownership interest
subsequent to the initial public offering of PDGR's common stock and warrants
as described in Note 3.

The accompanying financial statements of PDG Environmental, Inc. and
subsidiaries (the "Corporation") are unaudited.  However, in the opinion of
management, they include all adjustments necessary for a fair presentation of
financial position, results of operations and cash flows.  All adjustments made
during the three and nine months ended October 31, 1995 were of a normal,
recurring nature.  The amounts presented for the three and nine months ended
October 31, 1995 are not necessarily indicative of results of operations for a
full year.  Additional information is contained in the Annual Report on Form
10-K of the Corporation for the year ended January 31, 1995, as amended by Form
10-K/A No. 1 dated May 30, 1995, and should be read in conjunction with this
quarterly report.

Certain reclassifications have been made to the prior year financial statements
to conform with the current year presentation.

NOTE 2 - FEDERAL INCOME TAXES

No income taxes have been provided for the three and nine months ended October
31, 1995 due to a loss for financial reporting purposes.

Income taxes paid by the Corporation for the nine months ended October 31, 1995
and 1994 totaled approximately $75,000 and $17,000, respectively.

NOTE 3 - PDG REMEDIATION, INC.

INITIAL PUBLIC OFFERING

On February 9, 1995, PDGR sold in an initial public offering 1,000,000 shares
of common stock and 1,000,000 redeemable warrants at a price of $5.00 per share
of common stock and $0.10 per redeemable warrant.  The Corporation sold 400,000
shares of its PDGR common stock as part of the initial public offering and
received net proceeds of approximately $1.4 million, which resulted in a gain
of approximately $1.4 million during the six months ended July 31, 1995.  The
Corporation recorded the sale effective as of February 1, 1995.  PDGR sold
600,000 newly issued common shares plus 1,000,000 redeemable warrants and
received net proceeds of approximately $2.3 million.

The Corporation currently owns approximately 59.5% of PDGR common stock and
will continue to consolidate the accounts of PDGR as long as more than 50% of
the common stock is owned.

BUSINESS ACTIVITIES

The Corporation through its PDGR subsidiary has historically performed a
substantial amount of work under a Florida state funded site rehabilitation
program (the "EDI Program") which provides for the remediation of contaminated
sites related to the storage of petroleum and petroleum products.  The EDI
Program has undergone substantial modification during PDGR's current fiscal
year due to an imbalance between reimbursement application expenditures for
work performed under the EDI Program and revenues generated for the EDI
Program, as well as a concern that the majority of the site rehabilitation work
was being conducted at sites that are not considered to be high priority in
terms of the impact on drinking water supplies.





                                      7
<PAGE>   8
On March 8, 1995, Florida's Governor Lawton Chiles issued Executive Order 95-82
suspending processing of payment applications under the EDI Program and on
March 16 the Senate passed a temporary bill establishing a protocol for
continued work on sites based on their priority ranking and a pre-approval
process for both the scope and the cost of work for petroleum clean up program
tasks.

It was anticipated that the Florida legislature would pass final legislation to
amend the EDI Program prior to adjournment in May 1995; however, on May 11,
1995, the legislature adjourned for the year without acting on proposed changes
to the EDI program or the Inland Protection Trust Fund.  As a result of the
legislative inaction, PDGR has continued to work under the legislation passed
on March 27, 1995.

On July 26, 1995, the Florida Department of Environmental Protection ("FDEP")
issued guidance to contractors operating under the EDI Program for requesting
pre-approval from the FDEP prior to commencing work on eligible sites.  A
supplement was issued to this guidance on October 11, 1995 which contains
maximum allowable charges for contractors to employ in the pre-approval
process.

The change in the legislation surrounding the EDI Program has had a material
adverse effect on PDGR's operations during the second and third quarters of
fiscal 1996 since the number of sites in PDGR's backlog immediately eligible
for continued reimbursement were significantly reduced.  Further, PDGR's
thermal treatment services plant has experienced a significant decline in soil
shipments which PDGR believes is indirectly related to EDI Program changes
which has created a slowdown in the entire market for the thermal treatment of
petroleum contaminated soil and intense competitive price pressures.  As a
result of the aforementioned changes in the market for the thermal treatment of
petroleum contaminated soil, PDGR's plant remained idle for the majority of the
second quarter and the plant has experienced a significant reduction in volume
and price when comparing the nine months ended October 31, 1995 and 1994.

Additionally, the EDI Program changes and the indirect impact of these changes
on PDGR's thermal treatment services plant has resulted in substantial
reductions in PDGR's contract revenues resulting in operating losses in current
three and nine months ended October 31, 1995.  The Corporation expects these
contract revenue reductions and operating losses to continue into the fourth
quarter of this fiscal year.

PDGR has responded to the short-term impact of these revenue reductions through
prudent reductions in staff and other overhead costs, the reallocation of a
portion of its workforce to cover existing backlog at PDGR's Pennsylvania
remediation service operation and an intense marketing effort focused on
obtaining remediation service contracts for high priority sites eligible for
reimbursement under the current EDI Program and for remediation service
contracts outside the EDI Program.

During the past few months, PDGR has increased its backlog of high priority
sites eligible for participation in the EDI Program, which when combined with
the implementation of pre-approval procedures by the FDEP, should result in an
increase in utilization at PDGR's Florida remediation services operation and a
corresponding increase in contract revenues in fiscal 1997.  PDGR further
anticipates that the recently issued guidelines on maximum allowable charges as
part of the pre-approval process will result in lower margins recognized by
PDGR; however, PDGR believes that profitable operating margins are possible
provided the volume of work increases accordingly.

GEOLOGIC RECOVERY SYSTEMS

Due to the change in the market for the thermal treatment of soil and the
significant operating losses incurred by PDGR's facility during the nine months
ended October 31, 1995, PDGR is currently in the process of evaluating the
long-term prospects for its thermal treatment services plant.  At October 31,
1995, the thermal treatment services operation of the Corporation's thermal
treatment services plant had assets of $2.9 million and liabilities of $2.0
million.

The Corporation will also suffer a material adverse effect on its reported
financial results to the extent of its 59.5% ownership interest in PDGR due to
the changes described above.





                                      8

NOTE 4 - LINES OF CREDIT

The Corporation maintained certain lines of credit with CVD Financial
Corporation ("CVD Financial") which provided $3.6 million of combined
availability at January 31, 1995.  On February 27, 1995, the Corporation repaid
$1.1 million to CVD Financial with proceeds generated from the sale of its
40.5% interest in PDGR and the existing line of credit was reduced to $2.5
million.  On March 31, 1995, the expiration dated associated with the CVD
Financial line of credit was extended to July 1, 1995.

On October 31, 1995, the Corporation entered into an Amended and Restated Loan
Agreement with CVD Financial wherein the maximum borrowings under this line of
credit was set at $2,419,994.  The interest rate under this line of credit was
reduced from prime plus 7% to prime plus 3% and all amounts borrowed under this
line of credit are due and payable on December 31, 1996.  A term loan for
$559,991 was also provided as part of the Loan Agreement, with interest at the
prime rate of interest plus 3%.  The Term Loan requires monthly principal
payments of $13,533 plus interest.  Prior to the October 31, 1995 refinancing
CVD Financial held warrants to purchase 752,500 shares of the Corporation's
common stock at prices ranging from $0.75 to $1.25 per share.  As part of the
new Loan Agreement, CVD Financial continues to hold the warrants.

As part of the aforementioned Loan Agreement, CVD Financial was granted the
right to convert any portion of the outstanding balances of the line of credit
and the term loan, any time after January 31, 1996, into common stock of the
Corporation.  The Conversion Price is the lesser of the market price, as
defined, of the Corporation's common stock on January 31, 1996 or the market
price on the date of the Conversion Notice, except that the conversion price,
in neither case, shall not be less than $0.65 per share.  In the event that the
Corporation repays the line of credit and term loan prior to January 31, 1996,
the Corporation has the option of repurchasing the unexercised portion of the
aforementioned warrants for $100,000.

PDGR, a 59.5% owned subsidiary of the Corporation, maintained a $3.7 million
line of credit with CVD Financial which was repaid on February 27 and 28, 1995
with a combination of proceeds generated by PDGR from the initial public
offering of its common stock and borrowings under a line of credit as discussed
below which replaced the $3.7 million CVD Financial line of credit.

PDGR entered into a $5.0 million Credit Agreement with Barnett Bank of Central
Florida, N.A. (the "Barnett Bank Agreement") on February 8, 1995.  The Barnett
Bank Agreement was not funded until February 28, 1995 at which time PDGR used
the borrowings generated thereby to repay the $3.7 million line of credit with
CVD Financial.  The Corporation provides a guarantee under the Barnett Bank
Agreement.

As of June 2, 1995, PDGR was in default of certain covenants under the Barnett
Bank Agreement.  On June 14, 1995, PDGR entered into a forbearance agreement
with Barnett Bank pursuant to which the revolving line of credit was terminated
and the remaining principal balance currently outstanding under the Barnett
Bank Agreement was to be paid down through a combination of funds provided
under the agreement discussed below, collections on certain outstanding
accounts receivable balances and stipulated principal payments.  The
forbearance agreement provided that the maturity date relative to the remaining
outstanding principal balance was February 1, 1996.

PDGR also entered into a subcontract agreement to provide funding up to $5.0
million related to unbilled and future contract amounts for work performed
under the EDI Program.  The contractor also agreed, as part of the subcontract
agreement, to the assumption of approximately $1.2 million of outstanding
receivables under the EDI Program, previously held as collateral under the
Barnett Bank Agreement.

On June 26, 1995, the $5.0 million subcontract agreement was terminated as a
result of the contractor's inability to secure financing to fund the
subcontract work.  Accordingly, PDGR was unable to make the stipulated
principal payments totaling $1.3 million under the forbearance agreement as of
June 30, 1995.  Additionally, PDGR was also in default of certain financial
covenants under the Barnett Bank Agreement.

On August 8, 1995, PDGR entered into an amendment to the June 14, 1995 Barnett
Bank forbearance agreement which provided that PDGR convert the outstanding
loan balance to a term loan which matures on February 1, 1996.  Monthly
payments consist of a combination of collections on certain outstanding
accounts

receivable balances and stipulated principal payments.  At October 31, 1995,
the principal balance outstanding under the Barnett Bank Agreement, as amended,
was approximately $0.68 million.  Under the amendment to the forbearance
agreement, PDGR was granted a waiver of the financial covenants in the Barnett
Bank Agreement.  PDGR was also required to make a principal payment of $325,000
under the Amended and Restated Forbearance Agreement on August 25, 1995.  At
October 31, 1995, the principal balance outstanding under the Barnett Bank
Agreement, as amended, was approximately $0.68 million.  The $0.5 million cash
collateral reflected on the October 31, 1995 balance sheet was used to pay the
Barnett Bank loan on November 1, 1995.  As of November 30, 1995, the
outstanding balance under the Barnett Bank Agreement was approximately $0.13
million.

On January 27, 1995, PDG Environmental Services, Inc. ("PDGES"), a wholly-owned
subsidiary of PDGR, entered into a Master Funding and Indemnification Agreement
with Sirrom Environmental Funding, LLC, (the " Sirrom Agreement") to provide
$0.75 million of funding in connection with clean-up activities under the EDI
Program.  The Sirrom Agreement expires on January 27, 1997 and enables PDGR to
fund the amounts which PDGR bills under the EDI Program at the prime rate of
interest, as defined, plus 2%.  PDGR is advanced 100% of amounts billed and is
required to deposit 10% into an escrow account to cover potential
disallowances.  The Corporation and PDGR are guarantors on the Sirrom
Agreement.  As of October 31, 1995, PDGR was advanced approximately $0.74
million under the Sirrom Agreement.

On August 21, 1995, PDG Environmental Services, Inc., a wholly-owned subsidiary
of PDGR, entered into a Second Master Funding and Indemnification Agreement
with Sirrom Environmental Funding, LLC (the "Second Sirrom Agreement"), to
provide $4.0 million of funding relative to unbilled amounts under the EDI
Program.  The Second Sirrom Agreement, which expires on August 21, 1997,
enables PDGR to fund prospective amounts billed under the EDI Program at the
prime rate of interest, as defined, plus 3%.  Although PDGR will be advanced
100% of amounts billed, it is required to deposit 34% into an escrow account to
cover potential disallowances, future interest costs and a commitment fee of 2%
of the total funding provided.  PDGR also issued a warrant to purchase 100,000
shares of PDGR's common stock to Sirrom Environmental Funding, LLC at an
exercise price of $1.37 per share in conjunction with the execution of the
Sirrom Agreement.  The Corporation and PDGR are guarantors under the Sirrom
Agreement.  As of October 31, 1995, PDGR was advanced approximately $1.1
million under the Sirrom Agreement.

The Corporation paid interest costs totaling approximately $875,000 and
$846,000 during the nine months ended October 31, 1995 and 1994, respectively.

NOTE 5 - LONG TERM DEBT

PDGR is currently delinquent on one monthly installment ($55,000) on
sale/leaseback equipment financing.

NOTE 6 - COMPENSATION PLANS

The Corporation maintains a qualified incentive stock option plan (the "Plan")
which provides for the grant of incentive options to purchase an aggregate of
up to 400,000 shares of the common stock of the Corporation to certain officers
and employees of the Corporation and its subsidiaries.  Options to purchase
11,000 shares of the Corporation's common stock at an exercise price of $0.75
per share were granted under the Plan on May 23, 1995.  The options vest
one-third each year following the date of grant.

NOTE 7 - PREFERRED STOCK

Cumulative dividends in arrears on the Corporation's 2% Series A Preferred
Stock were approximately $103,000 at October 31, 1995.  At October 31, 1995,
there were 235,099 shares of Series A Preferred Stock outstanding.  The Series
A Preferred Stock is convertible into four shares of the Corporation's common
stock at the option of the preferred stockholder.

The conversion rate on the Series A Preferred Stock is also subject to
adjustment as a result of certain changes in the Corporation's capital
structure or distributions to common stockholders (except for cash dividends
permissible under law).





                                       10

At the Corporation's Annual Meeting of Stockholders held on July 23, 1993, in
exchange for the forfeiture of accrued but undeclared and unpaid dividends, the
holders of the Corporation's Series A Preferred Stock were granted a common
stock right which, if and when declared by the Board of Directors, will grant
to the holders of such common stock rights shares of the common stock of the
Corporation.  There were 840,214 common stock rights granted.

On May 23, 1995, the Board of Directors of the Corporation approved the
issuance of one-third of the shares reserved for the holders of such common
stock rights.  During the quarter ended July 31, 1995, 280,071 common shares
were issued to the holders of the common stock rights.  At October 31, 1995,
there were 560,143 common stock rights outstanding.

NOTE 8 - NET LOSS PER SHARE

The primary loss per common share for the three and nine months ended October
31, 1995 are computed by adjusting the net loss for the preferred dividend
requirement of $12,000 and $36,000, respectively, and dividing this amount by
the weighted average number of shares of common stock outstanding during the
respective period.  The effects of assuming the conversion of preferred stock
or the exercise of stock options, stock warrants and common stock rights would
be antidilutive for the three and nine months ended October 31, 1995.

Primary earnings per share for the three and nine months ended October 31, 1994
are calculated by dividing the net income by the average common shares
outstanding and dilutive common stock equivalents.  The effects of assuming the
exercise of stock options and warrants would be antidilutive for the three and
nine months ended October 31, 1994.

NOTE 9 - COMMITMENTS AND CONTINGENCIES

As discussed in further detail in Item 1. Legal Proceedings contained in Part
II located elsewhere herein, the Corporation has been named as a defendant in a
purported class action involving the purchase by all persons and entities of
PDGR common stock from February 9, 1995 through May 23, 1995.  The action
alleges that defendants violated certain federal securities laws.

The Corporation believes that the allegations are without merit or that there
are meritorious defenses to the allegations, and intends to defend the action
vigorously.  If, however, the plaintiff is successful in its claims, a judgment
rendered against the Corporation and the other defendants would likely have a
material adverse effect on the business and operations of the Corporation.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS

RESULTS OF OPERATIONS

THREE MONTHS ENDED OCTOBER 31, 1995 AND 1994

On February 9, 1995, the Corporation sold approximately 40.5% of its common
stock interest in its wholly-owned environmental services subsidiary, PDGR, in
an initial public offering of PDGR's common stock.  The Corporation recorded
the sale effective as of February 1, 1995 and continues to consolidate its
remaining 59.5% ownership interest.

The Corporation's contract revenues decreased by approximately 28% to $6.6
million during the three months ended October 31, 1995 compared to $9.1 million
in the three months ended October 31, 1994.  The Corporation's asbestos
abatement segment revenues were $5.3 million in the three month period ending
October 31, 1995 and 1994.  The Corporation's total revenues were impacted by a
significant reduction in the environmental remediation services segment's
revenues, which consists entirely of PDGR's operations.  PDGR reported $1.3
million of contract revenues in the current three month period compared to $3.8
million of contract revenues in the same three month period of the prior fiscal
year due to substantial changes in the EDI Program in late March 1995.

In the current three month period, PDGR's remediation service operation in
Florida experienced a 75% decline in contract revenues compared to the same
three month period of the prior fiscal year due to EDI Program changes which
have significantly reduced PDGR's available backlog of sites upon which it is
able to continue to perform work.  Further, PDGR's thermal treatment services
plant has experienced a 73% reduction in revenues when comparing the three
months ended October 31, 1995 and 1994 principally due to the uncertainties
created by the EDI Program changes which has significantly reduced the
petroleum contaminated soil market available for treatment within the state of
Florida.  The contract revenues associated with the PDGR's business outside of
the EDI Program at its Pennsylvania remediation service operation increased by
38% during the current quarter compared to the same quarter of a year ago as a
result of additional contract activity.

The Corporation's gross margin decreased to $0.9 million in the third quarter
of fiscal 1996 compared to $1.9 million in the third quarter of fiscal 1995.
The Corporation's asbestos abatement segment remained constant at $0.6 million
when comparing the three months ended October 31, 1995 and 1994.  The
environmental remediation segment which represents PDGR's operations reported
gross margins decreased to $0.3 million in the current three months compared to
$1.3 million in the prior year's three month period.  The significant decline
in the Corporation's gross margin results from reduced volume at its thermal
treatment services plant, which remained idle during the month of August 1995
and operated at historically reduced levels in September 1995 and October 1995,
and therefore contributed a negative gross margin in the current three months
compared to a gross margin contribution in excess of 40% in the same three
month period of the prior fiscal year.  PDGR's Florida remediation service
operation also experienced a significant decline in gross margin during the
current quarter due to the EDI Program changes which have reduced the available
backlog of work and resulted in a corresponding decline in sales volume.
PDGR's Pennsylvania remediation service operation experienced an increase in
gross margin associated with the increased sales levels in the current three
months and improved performance on certain jobs.

Selling, general and administrative expenses increased slightly to $1.43
million in the three months ended October 31, 1995 compared to $1.35 million in
the three months ended October 31, 1994.  Within the asbestos abatement
segment, selling, general and administrative expenses increased slightly to
$0.26 million in the current three month period compared to $0.25 million in
the same three month period of the prior fiscal year.  Selling, general and
administrative expenses within the environmental remediation services segment,
which represents PDGR, remained unchanged at $0.5 million during the third
fiscal quarter as compared with the prior year's third fiscal quarter.

The Corporation's selling, general and administrative expenses associated with
its corporate office increased to $0.58 million during the three months ended
October 31, 1995 from $0.39 million for the three months ended





                                       12
<PAGE>   13
October 31, 1994 due to the write off of costs associated with a contemplated
acquisition and deferred financing costs.  The Corporation also recognized
approximately $0.16 million and $0.21 million of selling, general and
administrative expenses associated with PDGR's corporate office in each of the
respective three month periods.

As a result of the factors described above, the Corporation reported a loss
from operations of $0.51 million in the current three month period compared to
income from operations of $0.55 million for the same three months of the prior
fiscal year.

The Corporation's reported interest expense decreased to $0.28 million for the
current fiscal quarter from $0.37 million for the prior year fiscal quarter.
The Corporation's interest expense remained unchanged at $0.12 million in the
current three month period as compared to the same three month period of a year
ago while PDGR's interest expense decreased to $0.16 million versus $0.25
million when comparing the three month periods as a result of a significant
reduction in outstanding indebtedness combined with lower interest rates in the
current three month period.

Interest income increased to $5,000 for the three months ended October 31, 1995
versus $4,000 for the three months ended October 31, 1994 due to higher
invested cash balances.

The Corporation reported a loss for financial reporting purposes during the
three months ended October 31, 1995, therefore, no income taxes have been
provided during the period.

During the three months ended October 31, 1994, the Corporation recorded an
income tax expense of approximately $16,000 to reverse its second quarter
income tax benefit.  It is expected that the Corporation will have no taxable
income in fiscal 1996.  PDGR has not recorded any income tax provision for the
three months ended October 31, 1995.

The Corporation recorded a 40.5% minority interest in the losses of PDGR of
approximately $0.2 million for the quarter ended October 31, 1995.  In the same
quarter of the previous fiscal year, PDGR was a wholly-owned subsidiary of the
Corporation.

NINE MONTHS ENDED OCTOBER 31, 1995 AND 1994

The Corporation's contract revenues decreased to $18.1 million for the nine
months ended October 31, 1995 compared to $24.7 million for the nine months
ended October 31, 1994.  The Corporation's asbestos abatement segment
experienced a decline in revenues during the current nine month period to $13.3
million versus $14.2 million in the same nine month period of the prior fiscal
year.  The reduction in asbestos abatement revenues is principally due to lower
sales volume during the first three months of the current nine month period due
to the postponement of certain projects.  The environmental remediation
services business segment's revenues, which represents PDGR, decreased to $4.9
million in the current nine month period versus $10.5 million in the prior year
nine month period.  The substantial decrease in revenues in the current nine
month period principally results from the previously described EDI Program
changes which resulted in a 35% reduction in contract revenues reported at
PDGR's Florida remediation services operation as a result of the EDI Program
changes which substantially decreased PDGR's available backlog of sites upon
which it is permitted to perform work.  In addition, PDGR's thermal treatment
services plant has experienced a significant reduction in volume in the current
nine month period.  PDGR believes that this reduction in volume is indirectly
related to the EDI Program changes which has created uncertainty in the entire
thermal treatment market.  Through the nine months ended October 31, 1995,
PDGR's thermal treatment services plant's volume is approximately 68% lower
than the corresponding nine month period of the prior fiscal year.  In
particular, PDGR's thermal treatment services plant was idle for the majority
of the second quarter of the current fiscal year.  PDGR's Pennsylvania
remediation service operation experienced a slight decline in revenue when
comparing the two nine month periods due to the timing of certain contract
activity.

The gross margin reported by the Corporation in the nine months ended October
31, 1995 decreased to $3.0 million compared to $5.0 million for the nine months
ended October 31, 1994.  Gross margins within the Corporation's asbestos
abatement segment increased to $1.7 million in the current nine months versus
$1.5 million in the same nine month period of the prior fiscal year due to
overall improvement in margins realized on





                                       13
<PAGE>   14
certain jobs.  The Corporation's overall decrease in gross margin is entirely
attributable to the gross margins experienced at PDGR which totaled $1.3
million and $3.4 million for the nine months ended October 31, 1995 and 1994,
respectively.  A significant reduction in volume and price at PDGR's thermal
treatment services plant during the nine months ended October 31, 1995 is the
principal reason for the lower gross margin experienced in the current nine
month period.  PDGR's thermal treatment services plant was idle for the
majority of the second quarter of the current fiscal year and the volume of
soil processed at the plant is 68% lower than the comparable nine month period
of the prior fiscal year which PDGR feels is indirectly attributable to the EDI
Program changes and the corresponding impact of these changes on the thermal
treatment market in the state of Florida.  PDGR's Florida remediation services
operation also experienced an overall lower gross margin in the nine months
ended October 31, 1995 due to the reduction in contract revenues associated
with the EDI Program changes.  When comparing the Florida remediation services
operation's gross margin as a percentage of contract revenues for the two nine
month periods, this operation actually experienced a higher gross margin
percentage in the current nine month period compared to the prior year's nine
month period.  PDGR's gross margin experienced at its Pennsylvania remediation
service operation decreased slightly in the nine months ended October 31, 1995
compared to October 31, 1994 due to slightly lower volume and the timing of
contract activity.

Selling, general and administrative expenses reported by the Corporation for
the nine months ended October 31, 1995 increased to $4.3 million versus $4.1
million in the same nine month period of the prior fiscal year.  Within the
Corporation's asbestos abatement segment, selling, general and administrative
expenses remained constant at $0.8 million when comparing the two nine month
periods of fiscal 1996 and fiscal 1995.  The Corporation's environmental
remediation segment, which represents PDGR's operations, reported an increase
in selling, general and administrative expenses to $1.48 million in the current
nine months compared to $1.37 million in the prior year's nine month period.

The current period increase is attributable to increased bidding activity at
PDGR's Florida remediation service operation in an effort to replace revenues
lost as a result of the EDI Program changes and increased bidding activity at
PDGR's Pennsylvania remediation services operation.  The Corporation's selling,
general and administrative expenses associated with its corporate office
totaled $1.9 million in each of the reported nine month periods.  Approximately
$1.45 million and $1.3 million of the selling, general and administrative
expenses in the nine month periods of fiscal 1996 and 1995, respectively,
related to the asbestos abatement corporate office of the Corporation.  The
increase was attributable to the aforementioned write off of costs associated
with a contemplated acquisition and deferred financing costs.  The corporate
office of PDGR represented $0.5 million of selling, general and administrative
expenses in the current nine month period compared to $0.6 million in the nine
months ended October 31, 1995 due to cost reduction efforts.

The Corporation reported a loss from operations of $1.3 million in the nine
months ended October 31, 1995 as a result of the factors discussed above
compared to income from operations of $0.9 million in the same nine month
period last year.

During the nine months ended October 31, 1995, the Corporation reported a net
gain of approximately $1.4 million from the initial public offering of common
stock and warrants by PDGR since the basis of the Corporation's investment was
lower than the proceeds realized from the initial public offering.  As a result
of the sale, the Corporation's ownership percentage in PDGR was reduced from
100% to 59.5% on an ongoing basis.

Interest expense decreased to $0.91 million in the current nine month period
compared to $0.92 million in the nine months ended October 31, 1994.  The
Corporation's interest expense for the nine months ended October 31, 1995
increased to $0.38 million versus $0.24 million for the nine months of the
prior fiscal year as a result of higher interest rates on outstanding
indebtedness, while PDGR's interest expense decreased to $0.53 million rom
$0.62 million due to a combination of lower interest rates on a significantly
reduced level of borrowing.

Interest income totaled $30,000 for the current nine month period versus
$10,000 in the same nine month period of the prior fiscal year due to higher
invested cash balances.  Approximately $12,000 of the Corporation's interest
income related to PDGR's operations.

The Corporation reported a loss for financial reporting purposes during the
nine months ended October 31, 1995 and 1994, therefore, no income taxes have
been provided.





                                       14
<PAGE>   15
During the nine months ended October 31, 1994, the Corporation's existing $2.5
million line of credit and an outstanding mortgage was sold to another lender
for a purchase price of 70% of the aggregate outstanding principal balance.
The new lender afforded the Corporation forgiveness of indebtedness in the
amount of $0.8 million in connection with the purchase of the loan from the
previous lender.  Accordingly, the Corporation recognized an extraordinary gain
of approximately $0.6 million associated with the extinguishment of debt, which
includes a $0.1 million charge related to the issuance of warrants and a $0.1
million income tax provision.

The Corporation recorded a 40.5% minority interest in the losses of PDGR of
$0.5 million for the nine months ended October 31, 1995.  In the same six
months of the previous fiscal year, PDGR was a wholly-owned subsidiary of the
Corporation.

LIQUIDITY AND CAPITAL RESOURCES

The Corporation's liquidity decreased during the nine months ended October 31,
1995 as cash and short-term investments decreased by $0.4 million to $0.3
million compared to no change in cash and short-term investments in the nine
months ended October 31, 1994.  As of October 31, 1995, the Corporation's cash
and short-term investment balance included $0.16 million related to PDGR, in
which the Corporation maintains a 59.5% ownership interest.  Pursuant to the
conditions of the Barnett Bank Agreement, PDGR is restricted from providing any
funds to the Corporation other than under a management services agreement.  The
Corporation's cash flows pertaining to PDGR's operations in the nine months
ended July 31, 1994 were unrestricted.

The decrease in cash during the current nine month period is principally
attributable to cash outflows associated with investing activities of $0.4
million and financing activities of $1.0 million.  These cash outflows were
offset by cash flows provided by operating activities of $1.0 million.

Cash inflows provided by operating activities of $1.0 million in the nine
months ended October 31, 1995 included $2.1 million of cash inflows related to
PDGR, offset by $1.1 million of cash outflows related to the Corporation.
These cash inflows included a $2.3 million reduction in accounts receivable, a
$1.8 million decrease in costs and estimated earnings in excess of billings on
uncompleted contracts related to the timing of certain contract activity, a
$0.5 million increase in accrued liabilities due to the timing of payments, and
$0.8 million of depreciation and amortization.  The aforementioned cash inflows
from operating activities were offset by a $1.1 million increase in cash held
in escrow and cash held as collateral on a loan to PDGR due to cash generated
from funding receivables and collections on accounts receivable, $0.9 million
decrease in accounts payable due to payments, $0.4 million decrease in billings
in excess of costs on uncompleted contracts related to the timing of contracts,
an adjustment of $1.4 million due to the gain on the sale of PDGR common stock
and $0.3 million as a result of the net loss generated in the period.

Cash inflows associated with financing activities during the current nine
months included $3.6 million of proceeds from the initial public offering of
PDGR stock, $1.4 million of which was received directly by the Corporation and
$2.2 million of which was received by PDGR.  PDGR also received $0.1 million
related to the sale of warrants in connection with the initial public offering.
Financing activities also included $3.7 million of proceeds from refinanced
indebtedness related to PDGR, offset by $8.5 million of repayments on
indebtedness primarily related to PDGR.  As discussed in Note 4, on October 31,
1995 the Corporation entered into an Amended and Restated Loan Agreement with
CVD Financial relating to the lines of credit and term loan provided by CVD
Financial.

The Corporation's investing activities of $0.4 million in the nine months ended
October 31, 1995 was attributable to the purchase of property, plant and
equipment.  Approximately $0.1 million of the property, plant and equipment
purchased related to PDGR.

During the nine months ended October 31, 1994, the Corporation's liquidity
remained unchanged.  Cash used by operating activities of $3.8 million and cash
used by investing activities of $0.2 million were offset by cash provided by
financing activities of $4.0 million.

The Corporation's cash outflows of $3.8 million to fund operating activities
principally included a $3.7 million increase in accounts receivable and a $2.1
million increase in costs and estimated earnings in excess of billings on
uncompleted contracts which related to the higher sales levels experienced in
the nine months ended October





                                       15
<PAGE>   16
31, 1994, and a $0.2 million decrease in deferred revenues related to the
timing of revenue recognition.  These cash outflows in operating activities
were offset in part by an increase in accounts payable of $0.9 million and an
increase in accrued liabilities of $0.6 million, both of these increases being
related to the timing of certain payments.

During the nine months ended October 31, 1994, cash outflows associated with
investing activities of $0.2 million included $0.4 million related to the
purchase of property, plant and equipment, offset in part by $0.2 million of
proceeds realized from the sale of property, plant and equipment.

The Corporation's cash inflows related to financing activities included $5.4
million related to the refinancing of the Corporation's existing line of credit
in March 1994 and the subsequent refinancing in June 1994 and borrowings on its
lines of credit.  These cash inflows were offset by principal payments on debt
of $1.5 million related to the Corporation's ongoing business activities and
amounts which were required to be repaid under two sale/leaseback transactions
in connection with the refinancing in March 1994.

At October 31, 1995, the Corporation's backlog associated with its asbestos
abatement business totaled $5.4 million ($3.3 million on fixed fee contracts
and $2.1 on time and materials or unit price contracts).  PDGR's backlog is
expected to result in revenues of approximately $1.2 million to $1.6 million
during the remainder of fiscal 1996.  As discussed below, PDGR's backlog has
experienced a significant decline due to changes in the EDI Program which have
significantly impacted PDGR's backlog on which it is able to perform work.
PDGR has replaced some of this backlog in the fourth quarter of fiscal 1996
with high priority sites eligible for participation in the EDI Program and
projects in the private municipal and federal markets.

The Corporation maintained certain lines of credit with CVD Financial
Corporation ("CVD Financial") which provided $3.6 million of combined
availability at January 31, 1995.  On February 27, 1995, the Corporation repaid
$1.1 million to CVD Financial with proceeds generated from the sale of its
40.5% interest in PDGR and the existing line of credit was reduced to $2.5
million.  On March 31, 1995, the expiration date associated with the CVD
Financial line of credit was extended to July 1, 1995.

On October 31, 1995, the Corporation entered into an Amended and Restated Loan
Agreement with CVD Financial wherein the maximum borrowings under this line of
credit was set at $2,419,994.  The interest rate under this line of credit was
reduced from prime plus 7% to prime plus 3% and all amounts borrowed under this
line of credit are due and payable on December 31, 1996.  A term loan for
$559,991 was also provided as part of the Loan Agreement, with interest at the
prime rate of interest plus 3%.  The Term Loan requires monthly principal
payments of $13,533 plus interest.

As part of the aforementioned Loan Agreement, CVD Financial was granted the
right to convert any portion of the outstanding balances of the line of credit
and the term loan, any time after January 31, 1996, into common stock of the
Corporation.  The Conversion Price is the lesser of the market price, as
defined, of the Corporation's common stock on January 31, 1996 or the market
price on the date of the Conversion Notice, except that the conversion price,
in neither case, shall not be less than $0.65 per share.

Since the Corporation is fully borrowed under its existing line of credit and
is limited in the amount of funds which can be provided by PDGR, the
Corporation's ability to meet its immediate and future liquidity requirements
is dependent upon the Corporation's ability to maintain profitability on an
ongoing basis.

PDGR, in which the Corporation maintains a 59.5% ownership interest, maintained
a $5.0 million Barnett Bank Agreement.  The Corporation is a guarantor under
this Barnett Bank Agreement.  As of June 2, 1995, PDGR was in default of
certain covenants under the Barnett Bank Agreement.  On June 14, 1995, PDGR
entered into a forbearance agreement with Barnett Bank pursuant to which the
revolving line of credit was terminated and the remaining principal balance
currently outstanding under the Barnett Bank Agreement was to be paid down
through a combination of funds provided under the agreement discussed below,
collections on certain outstanding accounts receivable balances and stipulated
principal payments.  The forbearance agreement provided that the maturity date
relative to the remaining outstanding principal balance was February 1, 1996.





                                       16
<PAGE>   17
PDGR also entered into a subcontract agreement to provide funding up to $5.0
million related to unbilled and future contract amounts for work performed
under the EDI Program.  Additionally, the contractor agreed, as part of the
subcontract agreement, to the assumption of approximately $1.2 million of
outstanding receivables under the EDI Program, previously held as collateral
under the Barnett Bank Agreement.

On June 26, 1995, the $5.0 million subcontract agreement was terminated as a
result of the contractor's inability to secure financing to fund the
subcontract work.  Accordingly, PDGR was unable to make the stipulated
principal payments totaling $1.3 million under the forbearance agreement as of
June 30, 1995.  Additionally, PDGR was also in default of certain financial
covenants under the Barnett Bank Agreement.

On August 8, 1995, PDGR entered into an amendment to the June 14, 1995 Barnett
Bank forbearance agreement which provides that PDGR will convert the
outstanding loan balance to a term loan which matures on February 1, 1996.
Monthly payments under the amended forbearance agreement consist of a
combination of collections on certain outstanding accounts receivable balances
and stipulated principal payments.  Under the amendment to the forbearance
agreement, PDGR was also granted a waiver of the financial covenants in the
Barnett Bank Agreement.  As of November 30, 1995, the outstanding balance under
the Barnett Bank Agreement has been reduced to $0.13 million.  PDGR anticipates
that the remaining balance will be repaid by January 31, 1996.

On January 27, 1995, PDG Environmental Services, Inc. ("PDGES"), a wholly-owned
subsidiary of PDGR, entered into the Sirrom Agreement which provides $0.75
million of funding in connection with clean-up activities under the EDI
Program.  The Sirrom Agreement expires on January 27, 1997 and enables the
Corporation to fund the amounts which the Corporation bills under the EDI
Program at the prime rate of interest, as defined, plus 2%.  The Corporation is
advanced 100% of amounts billed, plus is required to deposit 10% into an escrow
account to cover potential disallowances.  The Corporation and PDGE are
guarantors on the Sirrom Agreement.  As of October 31, 1995, the Corporation
was advanced approximately $0.74 million under the Sirrom Agreement.

On August 21, 1995, PDGES entered into the Second Sirrom Agreement which
provides $4.0 million of funding relative to unbilled amounts under the EDI
Program.  The Second Sirrom Agreement, which expires on August 21, 1997,
enables PDGR to fund prospective amounts billed under the EDI Program at the
prime rate of interest, as defined, plus 3%.  Although PDGR will be advanced
100% of amounts billed, it is required to deposit 34% into an escrow account to
cover potential disallowances, future interest costs, and a commitment fee of
2% of the total funding provided.  PDGR also issued a warrant to purchase
100,000 shares of PDGR's common stock at an exercise price of $1.37 per share
in conjunction with the execution of the Sirrom Agreement.  The Corporation and
PDGR are guarantors under the Second Sirrom Agreement.  As of October 31, 1995,
PDGR had been advanced $1.1 million under the Second Sirrom Agreement.

The Corporation will continue to monitor closely its short-term and long-term
liquidity requirements on an ongoing basis and is prepared to implement any
measures required to conserve cash to meet its needs and to satisfy its
obligations.

PROSPECTIVE INFORMATION

The Corporation's current business consists principally of asbestos abatement
contracting and a 59.5% ownership interest in PDGR, which is engaged in
providing environmental remediation services.  Given the limited growth
potential which currently exists within the asbestos abatement business, the
Corporation intends to actively pursue the further diversification of its
business into related environmental areas to the extent it is successful in
obtaining financing specifically to fund acquisitions.

The Corporation's reported financial results in future months are likely to be
adversely effected to the extent of its 59.5% ownership interest in PDGR which
it continues to consolidate for financial reporting purposes as a result of a
significant change in its business as discussed below.

During the nine months ended October 31, 1995, PDGR has experienced a
significant change in its business due to modifications in the EDI Program in
Florida.  A substantial amount of PDGR's historical revenues have been
generated by work performed under the EDI Program.  The changes in the EDI
Program, which are discussed in greater detail in Note 1, to the October 31,
1995 consolidated financial statements, has had a





                                       17
<PAGE>   18
material adverse effect on PDGR's operations since the number of sites in
PDGR's backlog immediately eligible for continued reimbursement under the EDI
Program was significantly reduced in the second and third quarters of fiscal
1996.  PDGR's thermal treatment services plant has also experienced a
significant decline in soil shipments which PDGR believes is indirectly related
to EDI Program changes which has created a slowdown in the entire market for
the thermal treatment of petroleum contaminated soil and competitive price
pressures.  As a result of the aforementioned changes in the market for the
thermal treatment of petroleum contaminated soil, PDGR's plant remained idle
for the majority of the second quarter and the plant has experienced a
significant reduction in volume and price when comparing the nine months ended
October 31, 1995 and 1994.

The aforementioned factors have resulted in substantial reductions in PDGR's
contract revenues resulting in operating losses in the current three and nine
months ended October 31, 1995.  PDGR expects these contract revenue reductions
and operating losses to continue into the fourth quarter of fiscal 1996.

PDGR has responded to the short-term impact of these revenue reductions through
prudent reductions in staff and other overhead costs, the reallocation of a
portion of its workforce to cover existing backlog at the Corporation's
Pennsylvania remediation service operation, and an intense marketing effort
focused on obtaining remediation service contracts for high priority sites
eligible for reimbursement under the current EDI Program and for remediation
service contracts outside the EDI Program.

During the past few months, PDGR has increased its backlog of private work and
of high priority sites eligible for participation in the EDI Program, which
when combined with the implementation of pre-approval procedures by the FDEP,
should result in an increase in utilization at PDGR's Florida remediation
services operation and a corresponding increase in contract revenues in fiscal
1997.  PDGR further anticipates that the recently issued guidelines on maximum
allowable charges as part of the pre-approval process will result in lower
margins recognized by PDGR; however, PDGR believes that profitable operating
margins are possible provided that the volume of work increases accordingly.
In spite of these efforts, PDGR believes it will continue to report losses for
the remainder of the fiscal year.  The Corporation will likewise report a loss
related to its 59.5% ownership interest in PDGR which is consolidated for
financial reporting purposes.

Due to the change in the market for the thermal treatment of petroleum
contaminated soil and the significant operating losses incurred by PDGR's
facility during the nine months ended October 31, 1995, PDGR is currently in
the process of evaluating the long-term prospects for its thermal treatment
services plant.  At October 31, 1995 the thermal treatment services operation
has assets of $2.9 million and liabilities of $2.0 million.

Both the Corporation, with respect to its 59.5% ownership interest in PDGR, and
PDGR are currently investigating all options in order to offset the adverse
impact on revenues and earnings as a result of the EDI Program changes.  These
options include the sale of all or a portion of the Corporation's remaining
investment in PDGR.

As discussed in further detail in Item 1. Legal Proceedings contained in Part
II located elsewhere herein, the Corporation has been named as a defendant in a
purported class action involving the purchase by all persons and entities of
PDGR common stock from February 9, 1995 through May 23, 1995.  The action
alleges that defendants violated certain federal securities laws.

The Corporation believes that the allegations are without merit or that there
are meritorious defenses to the allegations, and intends to defend the action
vigorously.  If, however, the plaintiff is successful in its claims, a judgment
rendered against the Corporation and the other defendants would likely have a
material adverse effect on the business and operations of the Corporation.

                          PART II-- OTHER INFORMATION

ITEM 1.  LEGAL PROCEEDINGS

With respect to the action captioned KLEIN v. PDG REMEDIATION, INC., described
in the registrant's Form 10-Q for the quarter ended July 31, 1995, on September
1, 1995, an answer was filed on behalf of the registrant, its officers and
directors and PDGE which generally denied the plaintiff's claims.

By letter dated December 5, 1995, the plaintiff requested a pre-motion
conference on a motion for class certification.  By letter dated December 6,
1995, the underwriter defendants requested a pre-motion conference on a motion
to dismiss the complaint.

The parties have begun initial discovery with respect to the action.

ITEM 3.  DEFAULTS UPON SENIOR SECURITIES

As discussed in Note 5 to the consolidated financial statements of the
registrant contained in Part 1 located elsewhere herein, the registrant is
currently delinquent in payments under a sale/leasehold agreement.  As of
December 14, 1995 the registrant is delinquent one installment in the amount of
$55,000, which includes principal and interest.

The registrant is currently in arrears with respect to the payment of dividends
on its Series A Preferred Stock.  At October 31, 1995, the cumulative dividends
in arrears on the Series A Preferred Stock were approximately $103,000.

ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

ANNUAL MEETING OF STOCKHOLDERS

On September 25, 1995 the Annual Meeting of the Stockholders of PDG

             Abstained                                5,279
</TABLE>

ITEM 5.  OTHER INFORMATION

On February 9, 1995, PDGR sold in an initial public offering 1,000,000 shares
of common stock and 1,000,000 redeemable warrants at a price of $5.00 per share
of common stock and $0.10 per redeemable warrant.  The registrant sold 400,000
shares of common stock as part of the initial public offering and received net
proceeds of approximately $1.4 million, which resulted in a net gain of
approximately $1.4 million during the three months ended April 30, 1995.  PDGR
sold 600,000 newly issued common shares plus 1,000,000 redeemable warrants and
received net proceeds of approximately $2.3 million.

The registrant currently owns approximately 59.5% of PDGR common stock and will
continue to consolidate the accounts of PDGR as long as more than 50% of the
common stock is owned.

The registrant's reported operations in future months are likely to be
materially adversely effected to the extent of its 59.5% ownership interest in
PDGR, which it continues to consolidate for financial purposes, as a result of
a significant change in its business as discussed in Note 3 to the consolidated
financial statements contained in Part I located elsewhere herein.

PDGES Debtor Parties and certain of their assets in which Lender had been
granted security interests were released from any obligations under the PDGE
Loans and Integra Loans in order to permit the public offer and sale of
securities of Remediation and the refinancing of the PDGES Loan by Barnett Bank
of Central Florida, the unpaid balance of the Integra Term Loan was included in
the balance of the Integra Revolving Loan, and the maturity date for the
Integra Revolving Loan and the PDGE Revolving Loan, inclusive of the Additional
PDGE Advance, were extended to April 1, 1995.

        G. On or about February 28, 1995, as contemplated by the February 7,
1995 Loan Modification Agreement, the PDGES Loan was repaid in full.

        H. Each of the PDGE Debtor Parties has requested that the PDGE
Revolving Loan and Integra Revolving Loan be consolidated, amended and restated
and the maturity date thereof be extended to December 31, 1996, the maturity
date of the PDGE Term Loan be reset at December 31, 1996, and the interest
rates under such loans reduced as set forth in the Amended and Restated
Revolving Note and Amended and Restated Term Note (as defined herein) and that
Lender agree to forbear from exercising its remedies respecting the Events of

the PDGE Debtor Parties), including the failure of the PDGE Debtor Parties to
pay the PDGE Revolving Loan and Integra Revolving Loan at their scheduled
maturity date of April 1, 1995, conditioned upon compliance by the PDGE Debtor
Parties with each of the provisions hereof, and has determined that Lender's
agreement to extend and modify such loans to undertake such waiver and
forbearance will substantially benefit such PDGE Debtor Party.

        I. Lender is willing to consolidate and extend the maturity date of the
PDGE Revolving Loan and Integra Revolving Loan, reset the maturity date of the
PDGE Term Loan, reduce the interest rates thereon and to otherwise modify,

             2.1.8   CONVERSION RIGHTS OF LENDER.

                                      -13-
<PAGE>   22
             (a)   CONVERSION PRICE; EXERCISE. At any time and from time to 
time after January 31, 1996, Lender may convert all or any portion of the
outstanding principal balance, and accrued but unpaid interest, owing on the
Loans into shares of common stock of PDGE at the Conversion Price (as defined
below) at any time prior to the repayment in full of the Loans upon notice to
PDGE (a "Conversion Notice"). The "Conversion Price" shall be the lesser of (i)
the Market Price per share of PDGE common stock on January 31, 1996, and (ii)
the Market Price of PDGE common stock on the date of the Conversion Notice
("Conversion Date"), but not less than $0.65 per share. The Market Price on any
given date shall equal the average closing price for shares of PDGE for the
twenty (20) trading days preceding the date for which the determination is
being made (a "Price Determination Period") as reported on NASDAQ or any
securities exchange on which the PDGE common stock is then listed, or if no
such prices are available, the average trading price as reported by any NASD
member firm selected by Lender for such Price Determination Period. Lender
agrees not to purchase or sell shares of PDGE common stock during the Price
Determination Period, other than any purchase pursuant to the Warrants or
otherwise from PDGE. Further, in determining the Market Price all purchases and
sales by any PDGE Debtor Parties, Guarantors or their Affiliates shall be
disregarded for the relevant Price Determination Period(s), and the PDGE Debtor
Parties agree to advise Lender in writing of any sales or purchases by any such
person within two (2) Business Days of leaning of any such transaction, and to
provide Lender with a copy of each report on Form 4 or Form 5 or Schedule 13D
received by PDGE within two (2) Business Days of receipt thereof. If the
outstanding shares of common stock of PDGE are increased, decreased, or changed
into, or exchanged for a different number or kind of shares or securities,
without receipt of consideration by PDGE, through reorganization, merger,
recapitalization, reclassification, stock split-up, stock dividend, stock
consolidation or otherwise, an appropriate proportionate adjustment shall be
made in the number and kind of shares into which the Loans are convertible and
the Conversion Price (including the $0.65 floor price otherwise applicable to
the Conversion Price). To determine the number of shares issuable upon
conversion, the amount to be converted shall be divided by the Conversion Price
in effect on the Conversion Date. Upon conversion, payment shall be made for
any interest accrued with respect to the principal amount so converted through
the Conversion Date (and which interest is not elected to be converted pursuant
to the Conversion Notice), and PDGE will deliver a check for any fractional
share based on the Conversion Price, together with a certificate representing
the shares issued to Lender, within five (5) days of receipt of the Conversion
Notice by PDGE. The Conversion Notice must specify the Loan and amount of the
Loan, principal and accrued interest to be converted into shares of common
stock of PDGE, the Conversion Price (subject to adjustment in the event the
PDGE Debtor Parties, Guarantors or their Affiliates have purchased or sold
shares during the relevant Price Determination Period) and instructions for the
issuance of a certificate representing the shares to be issued upon conversion
to Lender. PDGE shall keep reserved for issuance at all times a sufficient
number of shares of common

                                     - 14 -
<PAGE>   23
stock to permit the conversion in full of the Loan and the exercise of all
outstanding warrants granted to Lender.

             (b)   PREPAYMENT OF LOAN: EFFECT ON LOAN CONVERSION. Subject to
Lender's conversion rights as set forth in paragraph 2.1.8(a), the PDGE Debtor
Parties will have the right at any time and from time to time, upon not less
than fifteen (15) Business Days notice to Lender (a "Prepayment Notice") to
prepay all or any portion of the unpaid principal balance of the Loans without
penalty, but with interest accrued to the date of prepayment on the unpaid
principal balance of the Note so prepaid. Notwithstanding the foregoing, the
PDGE Debtor Parties shall not be required to provide Lender with advance notice
of any prepayment actually received by Lender on or prior to January 31, 1996.
If following the receipt of a Prepayment Notice, Lender does not elect to
convert the Loan to be prepaid pursuant to paragraph 2.1.8(a) above, the PDGE
Debtor Parties shall have 45 days, beginning on the earlier of (i) the 16th day
following receipt of the Prepayment Notice by Lender or (ii) the date that
Lender notifies PDGE that it does not intend to convert the prepayment during
which to complete the prepayment on the terms set forth in the Prepayment
Notice (the "Prepayment Period"). If PDGE subsequently fails to make a
prepayment equal to at least 75% of the prepayment proposed in the Prepayment
Notice prior to the end of the Prepayment Period, Lender's conversion rights
respecting the amounts of such proposed repayment shall be reinstated in full
and PDGE will immediately pay an amount equal to 5% of the difference between
the total prepayment proposed in the Prepayment Notice less the amount actually
repaid, which amount shall compensate Lender for the waiving during the
Prepayment Period of its conversion rights and which will not be applied to any
interest, principal or other sums owing under any Loan.

             (c)   REGISTRATION RIGHTS.

                  (i) At any time on or prior to October 1, 2000, Lender may 
make a written demand on PDGE for registration (a "Demand Registration") under
the Securities Act of 1933, as amended (the "Act") of all or a part of the 
shares issued upon conversion of the Loans ("Registrable Shares"). Lender 
shall be entitled to one Demand Registration only. Upon receipt of a Demand
Registration, PDGE shall take such steps as may be necessary to register such
securities under the Act as promptly as possible, including the preparation and
filing of a registration statement ("Registration Statement") with the
Securities Exchange Commission and all necessary amendments thereto, such
registration to take effect not later than sixty (60) days following the date
of Lender's demand. In addition, PDGE shall take such actions as may be
necessary and use its best efforts to register or qualify the Registerable
Shares for sale in such states and jurisdictions as Lender may direct on or
prior to the effective date of such Registration Statement under any local
securities or "blue sky" laws. All costs or expenses incident to the
registration, qualification or listing of such securities

                                     - 15 -
<PAGE>   24
shall be paid by PDGE, and PDGE shall comply with all reasonable requests of
Lender made in connection with the registration, qualification, listing or sale
of Registrable Shares. Without the prior written consent of Lender, PDGE shall
not effect any public sale or distribution of its debt or equity securities
during the ten (10)-day period prior to, or during the ninety (90)-day period
beginning on the effective date of a Registration Statement covering any
Registrable Shares. In addition to the foregoing, Lender shall remain entitled
to any registration rights provided under any of the Warrants.

             (ii) Notwithstanding the foregoing, PDGE shall be entitled to 
defer the filing of a Registration Statement required by Demand Registration 
for a period not to exceed sixty (60) days after receipt of such demand if: 
(i) PDGE is contemplating an underwritten public offering of its securities 
and, in the judgment of the managing underwriter thereof, such filing of the 
Registration Statement for the Demand Registration would have a material 
adverse effect on the PDGE's contemplated offering; (ii) PDGE is in possession 
of material information that it deems advisable not to disclose in a 
Registration Statement, provided that such information is revealed to Lender 
and Lender agrees with PDGE's decision not to disclose such information; 
or (iii) PDGE is prohibited (pursuant to the terms of an underwriting 
agreement previously approved by the Lender in connection with a public 
offering of its securities effected within the past six (6) months) from 
filing such Registration Statement.

             (iii) Lender shall also have the right, at any time and from time 
to time until October 1, 2000, to include Registrable Shares within any
Registration Statement filed by PDGE covering shares of its common stock other
than a Registration Statement filed solely with respect to any employee benefit
plan of PDGE (and provided that the form of Registration Statement is a type on
which Registrable Shares can be registered). PDGE shall promptly give written
notice to Lender of any intended registration of its Common Stock not less than
forty-five (45) days prior to the anticipated effective date of the
Registration Statement, and Lender shall, within fifteen (15) days of receipt
thereof, notify PDGE of the number of Registrable Shares it desires to include
in the Registration Statement. Subject to the approval of PDGE's managing
underwriter, Lender shall be entitled to include up to all of its Registrable
Shares, at its election, within the first Registration Statement filed by PDGE
following the date hereof. The number of Registrable Shares which may be
included by Lender in any such Registration Statement may be restricted by PDGE
if, in the opinion of PDGE's managing underwriter, the number of shares
proposed to be sold by Lender and by PDGE in such offering exceeds the number
of securities which can be sold in such offering. In such event, PDGE shall
include in the Registration Statement first the shares offered by PDGE, and
then to the extent approved for inclusion therein by PDGE and it managing
underwriter that number of Registrable Shares so approved pro rata with any
other shares of PDGE's common stock, the

                                     - 16 -
<PAGE>   25
holders of which have duly obtained registration rights of a type similar to
this paragraph c(iii). All costs or expenses, incident to the registration,
qualification or listing of such securities shall be paid by PDGE, and PDGE
shall comply with all reasonable requests of Lender made in connection with the
registration, qualification, listing or sale of Registrable Shares.

          (iv) Prior to October 1, 2000, PDGE shall not grant any registration 
rights superior to those provided to Lender with respect to Lender's Registrable
Shares without the prior written consent of Lender.

          (v) The registration rights granted in respect of the Registrable 
Shares hereunder shall be in addition to and not in lieu of those granted 
pursuant to the Warrants.

        (d)   BOARD REPRESENTATIVES. In the event Lender shall become the
holder of shares representing 20% or more of the voting power of PDGE, whether
as a result of the conversion of any Loan or the exercise of any Warrant, in
whole or in part, or otherwise, the PDGE Debtor Parties shall take such action
as may be necessary to include on the Board of Directors of PDGE, at Lender's
option and request, one or more directors nominated and appointed by Lender,
such directors to hold office until the next annual meeting of shareholders of
PDGE at which directors are to be elected. Further, the failure of the Board of
Directors of PDGE to nominate any nominee proposed by Lender for election at
such annual meeting or any other meeting at which directors are to be elected
shall constitute an Event of Default. The number of directors to be appointed
by Lender shall reflect, as nearly as possible, a percentage of the entire
membership of the Board of Directors of PDGE represented by Lender's nominees
equal to the percentage of PDGE's then issued and outstanding shares
represented by all shares of common stock of PDGE owned by Lender. The
director(s) shall be appointed to the Board of Directors by the existing
members of the Board of Directors within six (6) Business Days of Lender's
demand for such director(s) appointment delivered to PDGE. The Bylaws of PDGE
shall provide at all times for a sufficient number of authorized directors to
accommodate the appointment to the Board of Directors of the directors to be
nominated by Lender which may represent up to a majority of the entire Board of
Directors as constituted from time to time. The obligations of the PDGE Debtor
Parties hereunder shall survive any repayment of the Loan occurring by reason
of the conversion thereof into shares of common stock of PDGE but not any
repayment for cash. The obligations of the PDGE Debtor Parties hereunder shall
be specifically enforceable by Lender, it being agreed that no adequate remedy
at law shall exist for the breach of their obligation to cause Lender to be
afforded representation on the Board of Directors of PDGE.

        2.2   COLLATERAL. Payment of the Revolving Note and performance of all
of the Borrower's obligations under the Loan Documents will be secured by the
following collateral:

              2.2.1   SECURITY INTEREST. A first priority security interest 
(except for Permitted Title Exceptions) covering all of the Collateral, 
including without implied limitation, the Collateral described in the 
Mortgages, Security Agreement, Remediation Stock Pledge Agreement and 
Stock Pledge Agreement.

              2.2.2   GUARANTY. The Guaranty Agreement.

              2.2.3   MORTGAGES. The liens covering the Property as described
in the Mortgages.

              2.2.4   RECOURSE. The unlimited liability of the Borrowers.

        2.3   ADVANCES. Provided that no Event of Default has occurred and is
continuing, advances under the Revolving Note will be made by the Lender from
time to time on the request of the Borrowers, subject to the following
limitations:

              2.3.1   PURPOSE. The Lender will disburse funds under the Note 
for the following purposes: (a) to pay any fee owing to the Lender; (b) to 
reimburse the Lender for out-of-pocket expenses incurred by the Lender in 
connection with the preparation, administration and enforcement of the Loan 
Documents; (c) for working capital; and (d) such additional purposes as the 
Lender might approve from time to time.

              2.3.2   MAXIMUM ADVANCES. The maximum unpaid principal balance 
of the Revolving Loan at any time outstanding, as represented by the
Revolving Note, shall not exceed the lesser of (i) $2,419,993.71, less the
amount of any principal repaid to Lender other than a payment made solely to
restore the Loan-to-Value Ratio to no more than 100% as provided in paragraph
2.4 hereof, or (ii) the Borrowing Base.  As of October 31, 1995, the Revolving
Loan has been fully advanced.

              2.3.3   ADVANCE PROCEDURE. To obtain disbursements under the 
Revolving Note, the Borrowers will notify the Lender in writing of the total 
amount of the requested advance and will provide to the Lender such documents 
and information with respect to the advance and the Collateral as the Lender 
might reasonably request including, without limitation, a Borrowing 
Base Certificate.

                                     - 18 -
<PAGE>   27
                           2.3.4    Manner of Payment. On the Borrowers'
satisfaction of the requirements of this Agreement, the Lender will disburse the
approved amounts to as directed by the Borrower upon not less than three (3)
Business Days' notice.

                           2.3.5    Termination of Advances. The Lender will
have no obligation to make any advances or readvances under the Revolving Note
so long as an Event of Default has occurred and is continuing.

                           2.3.6    Further Assurances. To the extent that any
advance is made to acquire any asset by the Borrowers or any Affiliate, the
Borrowers will execute and deliver to the Lender and cause its Affiliates to
execute and deliver to the Lender such mortgages, security agreements, financing
statements and other instruments as might be reasonably requested by the Lender
to subject such asset to the liens created by the Loan Documents.

                           2.3.7    Optional Advances. Notwithstanding the 
limitations set forth in this paragraph 2.3, the Lender expressly reserves the 
right to waive the requirements herein contained from time to time and to 
permit the Borrowers, in the Lender's sole discretion, to obtain disbursements 
under the Revolving Note in such amounts and on such terms as the Lender might 
approve.

                  2.4      Loan Balancing. Throughout the term of the Loan, the
Borrowers agree to continuously maintain the unpaid balance of the Revolving
Note at an amount which is no greater than the maximum amount permitted by
paragraph 2.3.2. Without limiting the foregoing, if the unpaid balance of the
Revolving Note exceeds the Borrowing Base, the Borrowers agree to take such
action from time to time as might be necessary to restore the Loan-to-Value
Ratio to no greater than one hundred percent (100%) of the Borrowing Base,
including, without implied limitation, the reduction of the unpaid balance of
the Revolving Note by that amount which is in excess of the Borrowing Base.

                 2.5      Term Loan. The Term Loan will be repayable on the
following terms:

                          2.5.1     Amount. The Term Loan will be evidenced by
the Term Note in the face amount of $559,990.57.

                          2.5.2     Interest; Amortization. The Term Note will 
bear interest on the unpaid principal balance accrued from each date of
disbursement at the Term Note Rate calculated on the basis of the actual days
elapsed based on a per diem charge computed over a year composed of three
hundred sixty (360) days. The rate of interest


                                      -19-
<PAGE>   28
will be adjusted during the term of the Term Loan effective on the date of each
change in the Prime Rate. Interest on the amounts disbursed under the Term Note,
accrued from the date of each disbursement through the last day of each month,
will be paid on the first day of the succeeding month. The unpaid principal
balance of the Term Note will be paid in consecutive monthly installments of
Thirteen Thousand Five Hundred Thirty Three Dollars ($13,533) payable on the
first day of each month, with all remaining unpaid principal being due at
maturity.

                           2.5.3    Late Charge; Default Interest. If any 
payment of principal or interest is paid more than ten (10) days after when due,
the Borrowers will pay Lender a late charge equal to five percent (5%) of the
late payment. In addition, after an Event of Default, default interest may be
charged at a rate of 5.0% in excess of the Note Rate.

                           2.5.4    Maturity. Absent Default, the entire unpaid
balance of principal and accrued but unpaid interest owing on the Term Note
will be due and payable on December 31, 1996.

                           2.5.5    Prepayments. Subject to Lender's conversion
rights as set forth in paragraph 2.1.8(a) hereof, the Borrowers will have the
right at any time and from time to time, upon not less than fifteen (15)
Business Days' notice to Lender, to prepay all or any portion of the unpaid
principal balance of the Term Note without penalty, but with interest accrued to
the date of prepayment on the unpaid principal balance of the Term Note.
Notwithstanding the foregoing, the Borrowers shall not be required to provide
Lender with advance notice of any prepayment received by Lender on or prior to
January 31, 1996. In the event Lender exercises its rights to purchase stock
under the Warrant or any other warrant or option held by the Lender, all
proceeds payable to the Borrowers for the purchase of such stock shall be
utilized to repay the Term Note, to the extent such proceeds are not otherwise
used to repay the Revolving Note.

                  2.6      Collateral. Payment of the Term Note and performance
of all of the Borrower's obligations under the Loan Documents will be secured by
the following collateral:

                           2.6.1    Security Interest. A first priority security
interest (except for Permitted Title Exceptions) covering all of the Collateral,
including without implied limitation the Collateral described in the Mortgages,
Security Agreement, Remediation Stock Pledge Agreement and Stock Pledge
Agreement.

                           2.6.2    Guaranty. The Guaranty Agreement.

as described in the Mortgages.

                           2.6.4    Recourse. The unlimited liability of the
Borrowers.

                  2.7      Advances. The Term Loan has been fully advanced.

                           2.7.1    Optional Advances. Notwithstanding the
limitations set forth in this Paragraph 2.7, the Lender expressly reserves the
right to waive the requirements herein contained from time to time and to permit
the Borrowers, in the Lender's sole discretion, to obtain disbursements under
the Term Note in such amounts and on such terms as the Lender might approve.

                           2.7.2    No Readvances. The Term Loan shall not be a
revolving credit and Borrowers shall not be entitled to redraw upon or to obtain
readvances of any principal advanced to the Borrowers by the Lender and repaid
to the Lender hereunder. As of October 31, 1995 the Term Loan has been fully
advanced.

                           2.7.3    Conversion Rights of Lender. The Term Loan,
as well as the Revolving Loan, shall be convertible into shares of PDGE common
stock in accordance with paragraph 2.1.8(a) hereof.

         3.       Conditions of Lending. The obligations of the Lender to 
perform the terms of the Loan Documents and to make the initial and each
subsequent advance under the Revolving Note and/or Term Note are subject to the
performance by the Borrowers of the following conditions precedent and continued
compliance at all times with the following representations, warranties and
covenants:

                  3.1      Loan Documents. The Loan Documents shall have been
duly executed, acknowledged (where appropriate) and unconditionally delivered to
the Lender by the Borrowers (and Guarantors), all in form and substance
satisfactory to the Lender.

                  3.2      Title Evidence. The Lender shall have received
evidence satisfactory to the Lender that the Revolving Note and the Term Note
will be secured by perfected security interests covering the Collateral subject
only to the Permitted Title Exceptions.

                  3.3      Insurance. The Lender shall have received
certificates or policies of casualty and public liability insurance insuring the
Collateral issued in amounts, by companies and against such risks as are
reasonably satisfactory to the Lender, naming


                                      -21-
<PAGE>   30
the Lender as an individual insured or loss payee as the Lender might require,
together with evidence of premium payment and including such notice provisions
as Lender may require.

                  3.4      Opinion of Counsel. The Lender shall have received
the opinion of legal counsel to the Borrowers to the effect that:

                           3.4.1    Validity; Enforceability. The Loan Documents
constitute the legal, valid and binding obligations of the Borrowers, and the
Guarantors, as the case may be, enforceable against the Borrowers and the
Guarantors in accordance with their respective terms.

                           3.4.2    Violation. To the best knowledge of such
counsel, compliance by the Borrower and the Guarantors with the Loan Documents
will not violate any law which is applicable to the Borrowers or Guarantors or
any instrument or agreement binding on the Borrowers, the Guarantors or the
Collateral.

                           3.4.3    Action. To the best of counsel's knowledge
after appropriate inquiry, no action of any governmental authority or other
person is required in connection with the Borrowers' or the Guarantors'
execution, delivery or performance of the Loan Documents.

                           3.4.4    Status of Borrower. Each of the Borrowers:
(a) is a corporation duly organized, validly existing and in good standing under
the laws of the state of its incorporation; (b) has all requisite authority to
conduct its business and own and lease its properties, including the Collateral;
and (c) is qualified to do business in every jurisdiction in which the nature of
Borrower's business requires such qualification. The individuals executing the
Loan Documents on behalf of each Borrower have the power and authority to
execute, deliver and perform such Borrowers' obligations under the Loan
Documents.

                           3.4.5    Perfection. The Lender has good, valid and
perfected security interests in the Collateral described in the Financing
Statements. Upon delivery to Lender of the certificates representing the shares
of common stock of Remediation pledged to Lender under the Remediation Stock
Pledge Agreement to Lender, accompanied by duly executed stock powers, Lender
shall have a good, valid and perfected security interest in and to such shares
and the grant of such security interest to Lender shall not violate the rights
of any third party.

                           3.4.6    Litigation. To the best of such counsel's
knowledge, except for that action pending in United States District Court for
the Southern District of New


                                      -22-

<PAGE>   31
York, entitled Klein v. PDG Remediation, Inc., et al (Case No. CIV-4954), there
is no action, suit, proceeding or investigation pending or threatened against
the Borrowers or Guarantors or the Collateral which might materially and
adversely affect the Borrowers, any Guarantor, the Collateral or result in any
substantial uninsured liability or impair the ability of any Borrower to carry
on such Borrower's business as the same is conducted as of the date hereof.

                  3.5      Financial Information. The Lender shall have received
current financial statements of the Borrowers and the Guarantors prepared in
form acceptable to the Lender and which disclose financial conditions acceptable
to the Lender.

                  3.6      Compliance Documents. The Lender shall have received
the Borrowing Base Certificates, the Compliance Certificates, the Remediation
Certificates and such other instruments as the Lender might request pursuant to
the terms of this Agreement in the forms and at the times herein provided.

                  3.7      Authority. The Lender shall have received certified
copies of corporate resolutions and other documents reasonably required to
authorize the execution, delivery and performance of the Loan Documents, all in
form and substance satisfactory to the Lender.

                  3.8      No Default. The representations and warranties set
forth in paragraph 4 of this Agreement shall be true and correct in all material
respects and there shall not have occurred and be continuing any Event of
Default other than any Event of Default described in Schedule "A" hereto.

                  3.9      Use Restrictions. The Lender shall have received
satisfactory evidence that the Property and its use by the Borrowers complies
with all applicable zoning, use and building requirements imposed by any
governmental authority or private restriction.

                  3.10     Performance of Obligations. The Borrowers agree to
pay and perform all of the Borrower's obligations when due and prior to the date
on which penalties attach by reason of nonperformance.

                  3.11     Notice of Change. The Borrowers agree to give prompt
written notice to the Lender of:

Collateral free from all claims, liens, security interests, encumbrances and
title retention devices, other than Permitted Title Exceptions. The Borrowers

which are adverse to the Lender.

                  4.2      Litigation. Except as described in paragraph 3.4.6
above, there is no action, suit, proceeding or investigation pending or
threatened against the Borrowers or any Guarantor, or the Collateral which might

result in any substantial liability not adequately covered by insurance or
impair the ability of Borrower to carry on Borrowers' business as the same is
conducted as of the date hereof.

                  4.3      No Default. Execution and delivery by the Borrowers

regulation presently in effect.

<PAGE>   39
                  4.4      Financial Information. The financial information
delivered to the Lender relating to the Borrowers, the Guarantors and the
Collateral is correct, complete and fairly represents the financial condition 
and the results of operations of the Borrowers, the Guarantors and the value of 
the Collateral as of the dates of such financial information and there has 
occurred no material adverse change in such financial information.

                  4.5      Validity and Enforceability. The Loan Documents
constitute the legal, valid and binding obligations of the Borrowers or
Guarantors enforceable against the Borrower or Guarantors in accordance with
their respective terms.

                  4.6      Status of Borrowers. Each of Borrowers: (a) is a
corporation duly organized, validly existing and in good standing under the laws
of the state of its incorporation; (b) has all requisite authority to conduct
its business and own and lease its properties, including the Collateral; and (c)
is qualified to do business in every jurisdiction in which the nature of such
Borrower's business requires such qualification. The individuals executing the
Loan Documents on behalf of the Borrowers have the power and authority to
execute, deliver and perform Borrowers' obligations under the Loan Documents.

                  4.7      Compliance With Laws. No Borrower is an "investment
company" within the meaning of the Investment Company Act of 1940, as amended,
or a "holding company" or an "affiliate" of a "holding company" or a "public
utility" within the meaning of the Public Utility Holding Company Act of 1935,
as amended. The Borrowers are in compliance in all material decrees which are
applicable to the Borrowers or the Collateral including, without implied
limitation, all state and federal securities laws, the Employee Retirement
Income Security Act of 1974, as amended, the Fair Labor Standards Act,
Regulations of 1974, as amended, the Fair Labor Standards Act, Regulations G, T,
U and X of the Board of Governors of the Federal Reserve System and all
environmental, health and safety laws.

                  4.8      Environmental Liability. Neither any Borrower nor
any Affiliate, nor any prior owner or occupant of any property owned or occupied
by any Borrower or any Affiliate, is in material violation of any Environmental
Law or subject to any material claims (over One Hundred Thousand Dollars
($100,000) in the aggregate) for remediation of Hazardous Substances with
respect to any property owned or occupied by Borrower or any Affiliate.

                  4.9      Taxes. The Borrowers have filed all federal, state
and local tax returns which are required to be filed for the current and prior
tax years and have paid or made provisions for payment of all taxes which have
or may become due, except such taxes as are being contested in good faith and 
as to which adequate reserves have been provided. The Borrowers know of no 
basis for the assessment of any tax deficiency.

                  4.10     Future Operations. The Borrowers do not intend to
hinder, delay or defraud any existing or future creditor of the Borrowers or to
use the funds to be advanced by the Lender to the Borrowers to create any
preferential treatment of any creditor of the Borrowers in anticipation of
seeking relief under the Bankruptcy Code or any similar law.

                  4.11     Disclosure. No representation or warranty made by
the Borrowers in the Loan Documents contains any untrue statement of a material
fact or omits to state any material fact necessary to make the statements
therein not misleading. There is no fact known to the Borrowers which has or
might reasonably be anticipated to have a material adverse effect on the
business, assets, financial condition or operations of the Borrowers or the
value of the Collateral which has not been disclosed to the Lender in writing.

                  4.12     Priority. The security interests granted to Lender
pursuant to the Loan Documents constitute valid, perfected and, subject to the
Permitted Title Exceptions, first priority security interests encumbering the
Collateral described therein.

of Default provided under any of the Loan Documents, the Lender may exercise

money, guaranty, suretyship or similar agreement which shall remain uncured
after the expiration of any applicable cure period stated under the relevant
loan or other agreement. The PDGE Debtor Parties agree to promptly notify Lender

the delivery of the Borrowing Base Certificate required under the PDGE Loan

shall have occurred and be continuing beyond any applicable cure period, the
provisions of this paragraph 4.13(a) shall cease to apply as of the date that
each of the following conditions has been satisfied by the PDGE Debtor Parties:
(A) PDGE is not a guarantor or surety and is not otherwise obligated respecting
any indebtedness of any kind of Remediation, and PDGE, together with any
Remediation lender or other persons designated by Lender, shall provide to
Lender satisfactory evidence of the discharge or release of any guarantee,


                                     -32-
<PAGE>   41
suretyship or other obligation respecting the debts of Remediation; and (B)
neither PDGE, nor any Affiliate thereof shall hold, in the aggregate, more than
30% of the issued and outstanding shares of Remediation, and Remediation and
PDGE shall have provided Lender with satisfactory evidence concerning the
outstanding stock ownership of Remediation.

                           (b)      Minutes, etc. Beginning January 1, 1996,
Lender shall be provided a copy of all minutes and resolutions provided by any
PDGE Debtor Party to members of its Board of Directors within seven days of the
provision of such items to its directors.

                           (c)      Lock Box. At Lender's request, upon
occurrence of any Event of Default under any of the Loan Documents, which is not
cured to the satisfaction of Lender within any applicable cure period, the PDGE
Debtor Parties shall maintain in effect at all times with such bank or other
financial institution as may be designated by Lender, a lock box account or
accounts wherein all checks, drafts, cash and other remittances to the PDGE
Debtor Parties, in payment of their Accounts and other Collateral, shall be
deposited immediately for or in trust for the Lender until repayment in full of
all sums due from the PDGE Debtor Parties to Lender. Without in any way limiting
the foregoing, the PDGE Debtor Parties agree that:

                                    (i)     The PDGE Debtor Parties and Lender
shall be the only parties entitled to receive any payments from any Account
debtor respecting all accounts.

                                    (ii)    Upon demand by Lender, the PDGE
Debtor Parties hereby agree that all proceeds of the Accounts and other
Collateral which may be received by any PDGE Debtor Party shall be delivered,
transferred, assigned and endorsed in the exact form they are received, or as
otherwise directed by the Lender, and shall not be deposited or commingled with
any other assets of any PDGE Debtor Party. In the event a PDGE Debtor Party
receives any payments it was unauthorized to receive, they shall be held in
trust for Lender and shall be delivered to Lender or its designated bank or
financial institution in the exact form received except for any endorsement of
the PDGE Debtor Party where necessary to permit collection, which the PDGE
Debtor Parties hereby agree to make.

                                    (iii)   The PDGE Debtor Parties further
agree to immediately notify the account debtors under the Accounts and other
Collateral to make payments of all sums due, at Lender's option, directly to the
Lender or to the lock box account at such address as may be directed by Lender,
and to indicate on all invoices to such account debtors that all payments are to
be made directly to the Lender or to the lock box. The PDGE Debtor Parties shall
provide Lender with copies of any such notices concurrent with the delivery
thereof to the account debtors, and of all invoices sent after the date Lender
gives notice of its intention to implement these lock box provisions. Any lock
box


                                     -33-
<PAGE>   42
maintained may, at Lender's option, be maintained in the name of any one or more
PDGE Debtor Parties but Lender shall have the sole access to such lock box.

                                    (iv)    The PDGE Debtor Parties hereby
jointly, severally and irrevocably appoint the Lender the attorney-in-fact of
each and all of them to do (but the Lender shall not be obligated to and will
not incur any liability to any third party for any failure so to do) any act
which any PDGE Debtor Party is obligated by any Loan Document of any kind to do,
including without implied limitation, the collection, endorsement and receipt of
all payments or proceeds payable on or on account of the Accounts or the
delivery of any notices, including any notices to account debtors.

                                    (v)     The foregoing lock box and
collection provisions may be implemented by Lender in its sole and absolute
discretion upon its determination that an Event of Default has occurred and has
not been cured within any applicable cure period, and Lender shall not have any
liability of any kind to any PDGE Debtor Party or any other person in the event
Lender has incorrectly determined that an Event of Default exists, it being
understood that the parties acknowledge that Lender has, as of the date hereof,
the sole, absolute and unrestricted right to currently impose such lock box
requirements upon the PDGE Debtor Parties or to directly collect all Accounts.

                           (d)      Accounts Receivable Information. In addition
to the account receivables aging report delivered each month to Lender under the
terms of paragraph 3.13.5 hereof, the PDGE Debtor Parties will provide
supplementary information sufficient to show the customer names, addresses,
phone and fax numbers for each account debtor of the PDGE Debtor Parties,
together with the name of the principal contact of the PDGE Debtor Parties at
such customer.

                           (e)      Joint Ventures; Investments. Paragraph 3.22
of this Agreement restricts the authority and power of the PDGE Debtor Parties
to make investments in or loans to other entities or parties, including joint
ventures or partnerships. Lender agrees that it will consider, on a case by case
basis, any proposed joint venture, partnership or similar investment by any PDGE
Debtor Party; provided, that (A) written approval of such investment is obtained
from Lender prior to the entering into of any binding commitment of any kind by
any PDGE Party to make such investment; (B) the PDGE Debtor Parties provide
Lender with such information as Lender may request concerning the proposed
investments; (C) no Event of Default shall exist and be continuing, without
reference to any cure period which otherwise would be applicable; (D) no portion
of Lender's Collateral including any proceeds of any Collateral, shall be
utilized to fund or guarantee or secure such investment; and (E) Lender shall
obtain such security interests in such investment or in the assets of such joint
venture, partnership or similar investment as it shall require.


                                      -34-
<PAGE>   43
                           (f)      Affiliates; Investments. Schedule "J" hereto
contains a complete list of all corporations, joint ventures, partnerships, or
other entities or persons in which any PDGE Debtor Party has any equity interest
or interest as a lender, including without limitation all subsidiaries and
Affiliates.

                           (g)      Remediation Stock Ownership. The PDGE Debtor
Parties each hereby covenant and agree that until repayment in full of the
Loans, PDGE shall own at all times, free and clear of any liens or security
interests, other than Lender's security interest arising under the Remediation
Stock Pledge Agreement, all shares owned by the PDGE Debtor Parties in
Remediation (the "Remediation Shares") and shall only sell such shares for the
purpose of repaying the Loans, and all proceeds of any sale of the Remediation
shares pledged to the Lender shall be paid to the Lender to be applied to reduce
the outstanding balance of the Loans, as the Lender shall determine to apply
such funds.

                           (g)      Remediation Stock Ownership. The PDGE Debtor
Parties each hereby covenant and agree that until repayment in full of the
Loans, PDGE shall own at all times, free and clear of any liens or security
interests, other than Lender's security interest arising under the Remediation
Stock Pledge Agreement, all shares owned by the PDGE Debtor Parties in
Remediation (the "Remediation Shares") and shall only sell such shares for the
purpose of repaying the Loans, and all proceeds of any sale of the Remediation
shares pledged to the Lender shall be paid to the Lender to be applied to reduce
the outstanding balance of the Loans, as the Lender shall determine to apply
such funds.

                           (h)      The PDGE Debtor Parties jointly and 
severally warrant, represent and covenant that:

                                    (i)     Except as set forth in the
Securities Act of 1933, as amended (the "Act"), there are no restrictions upon
the transfer of any of the Remediation Shares and PDGE has the right to pledge
and grant a security interest in or otherwise transfer the Remediation Shares
free of any encumbrances or rights of third parties and all Remediation Shares
shall be held as Collateral as defined under the Remediation Stock Pledge
Agreement;

                                    (ii)    All of the Remediation Shares are
and shall remain free from all liens, claims, encumbrances, and purchase money
or other security interests. PDGE shall not, without Lender's prior written
consent, sell, transfer or otherwise dispose of any or all of the Remediation
Shares;

                                    (iii)   The Remediation Stock Pledge
Agreement, and the delivery to Lender of the Remediation Shares, creates a valid
and perfected security interest in the Remediation Shares and all actions
necessary or desirable to such perfection have been duly taken;

                                    (iv)    Except as set forth in the Act no
authorization or other action by, and no notice to or filing with, any
governmental authority or regulatory body is required either (A) for the
perfection of or exercise by Lender of its rights and remedies under the
Remediation Stock Pledge Agreement (except as may have been taken by or at the
direction of Lender or as may be required in connection with a disposition of
Remediation Shares by laws affecting the offering and sale of securities
generally), or (B) for the exercise by Lender of the voting or other rights
provided for in the Remediation


                                      -35-
<PAGE>   44
Stock Pledge Agreement or the remedies in respect of the Remediation Shares
pursuant to the Remediation Stock Pledge Agreement;

                                    (v)     The Remediation Shares represent
59.5% percent (100%) all of the issued and outstanding shares of capital stock
of Remediation;

                                    (vi)    PDGE holds no options, warrants or
other rights to acquire capital stock of Remediation; and

                                    (vii)   All of the Remediation Shares have
been duly and validly issued, and they are fully paid and nonassessable.

                                    (viii)  All of the Remediation Shares have
been registered under the Act, as amended, and registered or qualified for sale
under the laws of each state in which shares were sold in connection with
Remediation's initial public offering in February 1995, and are the subject of a
current prospectus under the Act.

                  4.14     Additional Matters. Each of the PDGE Debtor Party and
Guarantors represents and warrants that they (a) have been advised by legal
counsel of the their choice in the transactions contemplated by the Agreement;
(b) are fully aware and clearly understands all of the terms and provisions
contained in this Agreement; (c) have voluntarily, with full acknowledge and
without coercion or duress of any kind, entered into this Agreement; (e) on
their own initiative have made proposals to the Lender, the terms of which are
reflected by this Agreement; and (f) have received actual and adequate
consideration to enter into this Agreement.

         5.       Environmental Compliance. The Borrowers agree that they will
not use, generate manufacture, produce, store, release, discharge or dispose of
any Hazardous Substance or allow any other person to do so in violation of any
Environmental Law. The Borrowers agree to give prompt written notice to the
Lender of: (a) any proceeding or inquiry by any federal, state, local or foreign
governmental authority with respect to any violation of Environmental Law by the
Borrowers or any Affiliate; (b) all claims made or threatened by any third party
against the Borrowers or any affiliate relating to any loss or injury resulting
from any Hazardous Substance; and (c) the discovery by the Borrowers or any
Affiliate of any occurrence or condition that could cause the Borrowers or any
Affiliate to be subject to any restrictions on the ownership, occupancy,
transferability or use of any property of the Borrowers under any Environmental
Law. The Borrowers agree to protect, indemnify and hold harmless the Lender, its
directors, officers, employees, agents, successors and assigns against all loss,
damage, cost, expense or liability (including reasonable attorneys' fees and
costs) directly or indirectly arising out of or attributable to the use,
generation, manufacture, production, storage, release, threatened release,
discharge, disposal or presence of a Hazardous Substance by the Borrowers or any
Affiliate,


                                      -36-
<PAGE>   45
including without implied limitation: (i) all foreseeable consequential damages;
and (ii) the costs of any required or necessary repair, cleanup or
detoxification and the preparation and implementation of any closure, remedial
or other required plan. The foregoing indemnity agreement will survive the
payment of the Loan and the release or other termination of the Loan Documents.
In the event that any investigation, site monitoring, containment, cleanup,
removal, restoration or other remedial work of any kind or nature is reasonably
necessary or desirable under any applicable Environmental Law or required by any
governmental or nongovernmental entity or person because of, or in connection
with, the current or future presence, suspected presence, release or suspected
release of a Hazardous Substance on or into the air, soil, groundwater, surface
water or soil vapor by the Borrowers or any Affiliate, the Borrowers agree
within thirty (30) days after written demand for performance thereof by the
Lender (or such shorter period of time as might be required under any applicable
Environmental Law) to commence, or cause to be commenced, and thereafter
diligently prosecute or cause to be prosecuted to completion, all such remedial
work. At Lender's option, remedial work will be performed by one or more
contractors approved by the Lender under the supervision of a consulting
engineer approved by the Lender. All costs and expenses of such remedial work
will be paid by the Borrowers including, without implied limitation, the charges
of such contractor(s) and consulting engineer(s), and the Lender's reasonable
attorneys' fees and costs incurred in connection with monitoring or review of
such remedial work.

         6.       Events of Default. The Lender may terminate all obligations of
the Lender to make further disbursements under the Revolving Note or Term Note
and may exercise the remedies held by the Lender under the Loan Documents if any
of the following events occur and are not remedied by the Borrowers or waived in
writing by the Lender.

                  6.1      Nonpayment. The nonpayment, within five (5) days of
the date when due, of any installment of interest or principal owing under the
Revolving Note or Term Note or of any other amount payable to the Lender under
the terms of the Loan Documents.

                  6.2      Breach of Agreement. The failure by the Borrowers to
perform or observe any representation, warranty or agreement contained in any of
the Loan Documents, including without implied limitation any provision of
paragraphs 3, 4 and 5 hereof, which shall continue for a period of thirty (30)
days after the Borrowers become aware thereof, except that any obligations
related to the payment of money or maintenance of insurance shall have no grace
period except as otherwise expressly provided in paragraph 6.1 hereof and the
defaults described in paragraph 6.3 through 6.12 shall have no grace periods
except as specified in such paragraphs.

                  6.3      Lien Filings. The existence for a period of thirty
(30) days of any lien other than liens created by the Loan Documents or
permitted hereunder covering all


                                      -37-
<PAGE>   46
or any portion of the Collateral, unless the validity thereof is being contested
in good faith by the Borrowers.

                  6.4      Casualty Loss. Substantial damage, destruction or
taking of all or any portion of the Collateral.

                  6.5      Representations and Warranties. Any representation,
statement, certificate, schedule or report made or furnished to the Lender by or
on behalf of the Borrowers proves to be false or erroneous in any material
respect at the time of the making thereof or any representation or warranty
contained in the Loan Documents ceases to be complied with in any material
respect.

                  6.6      Insolvency; Bankruptcy. The insolvency (meaning an
inability to pay debts as the same become due or the existence of liabilities in
excess of assets) of any Borrower or any Guarantor, or the institution of
bankruptcy, reorganization, liquidation, receivership or conservatorship
proceeding by or against any Borrower or any Guarantor.

                  6.7      Judgment. Entry by any court of a final uninsured
judgment against any Borrower or an attachment of the Collateral or any part
thereof which is not discharged or stayed to the satisfaction of the Lender.

                  6.8      Other Debt. The default in payment or acceleration of
the maturity of any indebtedness of any Borrower or any Guarantor owing to any
other person.

                  6.9      Adverse Change. The occurrence of a material adverse
change in the financial condition of any Borrower, any
Guarantor, or the value of the Collateral.

                  6.10     Ownership and Management. A change in the ownership
or management of the Borrowers shall occur which is unsatisfactory to Lender.

                  6.11     Corporate Existence. Any act or omission (formal or
informal) of the Borrowers or Guarantors or their officers, directors or
shareholders leading to, or resulting in, the termination, invalidation (partial
or total), revocation, suspension, interruption or unenforceability of their
corporate existences, rights, licenses, franchises or permits, or the transfer
or disposition (whether by sale, lease or otherwise) to any person of all or a
substantial part of their property.

                  6.12     Invalidity of Security Interest and Liens. For any
reason after execution and delivery thereof, any document delivered pursuant
hereto that creates, or was intended to create, a security interest or to
provide collateral security for indebtedness created hereunder ceases to be in
full force and effect, or the liens intended to be created


                                      -38-
<PAGE>   47
thereby cease to be or are not valid and perfected first liens, subject to no
other liens except as expressly permitted herein.

         7.       Remedies. On the occurrence of an Event of Default, in
addition to any other rights and remedies which the Lender might hold under the
terms of any one or more of the Loan Documents, the Lender will have the
following remedies:

                  7.1      Acceleration of Maturity. The Lender may, at the
Lender's option, terminate all obligations of the Lender to make further
advances under the Revolving Note and the Term Note, declare the Revolving Note
and the Term Note and all other amounts owing by the Borrowers to the Lender to
be immediately due and payable, demand performance of all other obligations of
the Borrowers under the Loan Documents and proceed to selectively and
successively enforce any one or more of the Lender's rights under the Loan
Documents.

                  7.2      Selective Enforcement. In the event the Lender elects
to selectively and successively enforce the Lender's rights under any one or
more of the Loan Documents, such action will not be deemed a waiver or discharge
of any other right, lien or encumbrance securing payment of the Revolving Note
and the Term Note. Lender may proceed against the Guarantors or the Borrowers
selectively and without any requirement to proceed against all of them or
against any of them in any particular order.

                  7.3      Performance by Lender. In the event the Borrowers
fail to cure or cause to be cured any Event of Default within any time provided,
the Lender will at any time thereafter have the right, but not the obligation,
to cause the Event of Default to be cured on the Borrowers' behalf and to pay
any secured or unsecured claim (whether prior to or subordinate to the claims of
the Lender) affecting the Collateral or Lease payments in such manner and at
such times as the Lender determines to be appropriate under the circumstances.
The Borrowers hereby authorize the Lender to increase the indebtedness owing by
the Borrowers to the Lender by the cost of curing any Event of Default or
satisfying any claim against the Borrowers or the Collateral and agrees that the
Loan Documents will evidence and secure payment of such costs whether or not the
total funds advanced by the Lender exceed the face amount of the Loan Documents.

                  7.4      Waiver of Default. The Lender may, by an instrument
in writing signed by the Lender, waive any Event of Default which has occurred
and any of the consequences of such Event of Default and, in such event, the
Lender, the Borrowers and the Guarantors will be restored to their respective
former positions, rights and obligations hereunder. Any Event of Default so
waived will, for the purposes of the Loan Documents, be deemed to have been
cured and not to be continuing, but no such waiver will extend to any subsequent
or other Event of Default or impair any consequences of such subsequent or other
Event of Default. No waiver of any Event of Default by the Lender will be


                                      -39-

<PAGE>   48
implied from the failure or delay by the Lender to take any action in respect of
the Event of Default. No express waiver of any condition precedent or Event of
Default will affect any other Event of Default or extend any period of time for
performance other than as specified in such express waiver. One or more waivers
of any Event of Default will not be deemed a waiver of any subsequent failure by
the Borrowers to perform the same provision or any other provision. The consent
to or approval of any act or request by the Lender will not be deemed to waive
or render unnecessary the consent to or approval of any subsequent similar act
or request. The partial exercise of any right or remedy under the Loan Documents
will not preclude any other or further exercise thereof or the exercise of any
other right or remedy. No advance of the proceeds of the Loan will constitute a
waiver of any of the Borrowers' representations, warranties, conditions or
agreements contained in the Loan Documents. If the Lender elects to advance
proceeds of the Loan to the Borrowers' notwithstanding the Borrowers' failure to
satisfy any condition precedent to such advance, the advancement of funds will
not preclude the Lender from thereafter declaring the Borrowers' failure to
satisfy such condition precedent to be an Event of Default. No course of
dealing between the Borrowers and the Lender will be deemed to amend the terms
of the Loan Documents or to preclude the Lender from exercising the rights and
remedies therein contained notwithstanding such course of dealing.

                  7.5      Cumulative Remedies. The rights and remedies of the
Lender provided by the Loan Documents are cumulative and no right or remedy will
be exclusive of any other or of any other right or remedy which the Lender might
otherwise have by virtue of the occurrence of an Event of Default and the
exercise of any right or remedy by the Lender will not impair the Lender's
standing to exercise any other right or remedy.

                  7.6      Waiver of Marshalling of Assets. The Borrowers,
jointly and severally, for themselves and all who may claim through or under
them, hereby expressly waive and release all rights to have the Collateral, or
any part thereof, or any of their other properties, marshalled on any
foreclosure, sale or other enforcement of remedies, and the Lender or any court
in which the foreclosure of liens or security interests in the Collateral are
sought, shall have the right to sell the Collateral as an entirety in a single
parcel.

                  7.7      Deposits; Setoff. Regardless of the adequacy of the
Collateral, any sums credited by or due from the Lender or any affiliate of the
Lender to the Borrowers or any affiliate of the Lender will at all times
constitute collateral security for all obligations of the Borrower to the Lender
and may be set off against any and all liabilities, direct or indirect, absolute
or contingent, now existing or hereafter arising, of the Borrower to the Lender.

         8.       Rights of Lender Concerning New Financing; Refinancing of
Property; Repurchase of Warrants.


                                      -40-
<PAGE>   49
                  8.1      Financing Proceeds. Out of all proceeds received by
any PDGE Debtor Party as a result of the completion of any equity financing (a
"Financing"), except a "Lender Equity Financing" as defined below, net of all
selling expenses incident thereto, consisting of all brokerage and underwriting
commissions, discounts, placement agent fees, and other related compensation,
attorneys' and accountants' fees, printing costs, filing fees and other
necessary expenses ("Net Financing Proceeds") a minimum of thirty percent (30%),
or one hundred percent (100%) should any Event of Default have occurred and be
continuing beyond any applicable cure period, shall be used solely for the
purpose of repaying the amounts owing under the Loans, whether or not then due,
as Lender may determine, and Lender is hereby granted a security interest in all
such Net Financing Proceeds to the extent Lender is entitled to same hereunder.
However, to the extent Net Financing Proceeds are derived from the issuance of
shares of PDGE common stock at any time upon the exercise by Lender of any
Warrants, in whole or in part, one hundred percent (100%) of such Net Financing
Proceeds shall be applied to repayment of the Loans and Lender may credit the
proceeds otherwise due Lender on such issuance directly to the amounts owing to
Lender under the Loans. Lender shall have the right to require as a condition of
any investment, securities purchase, underwriting, placement agent, or similar
agreement related to any Financing that the Net Financing Proceeds be paid
directly to Lender or as Lender may otherwise direct. The PDGE Debtor Parties
agree to execute and deliver, and hereby irrevocably authorize Lender, on their
behalf and as their attorney-in-fact, to execute and deliver, any and all
agreements and instruments, and to take any and all actions, as Lender may
request or deem necessary in order to provide for the direct payment of all Net
Financing Proceeds to Lender, or to perfect Lender's security interest in such
Net Financing Proceeds as granted herein. The PDGE Debtor Parties shall provide
Lender with at least fifteen (15) Business Days notice prior to the closing of
any Financing.

                  8.2      Option to Provide Financing. In the event any PDGE
Debtor Party shall propose to raise any funds through a Financing, such PDGE
Debtor Party shall offer Lender the first right or option to provide such
Financing and shall provide Lender with a notice (the "Offer Notice") setting
forth all material terms of the proposed Financing, including the nature of the
equity securities to be issued, the rights thereof and the price to be paid
therefor. Following receipt of the Offer Notice, Lender shall have the right
upon notice to the PDGE Debtor Party proposing the Financing given within
fifteen (15) Business Days of receipt of the Offer Notice to provide the
Financing requested by the PDGE Debtor Party on substantially the terms set
forth in the Offer Notice (a "Lender Equity Financing"). In the event Lender
shall exercise its right to provide funds to a PDGE Debtor Party through a
Lender Equity Financing, the parties shall use their best efforts to agree upon
the terms of and to enter into definitive agreements respecting such Financing
as are customary for a transaction of such type and to close the Lender Equity
Financing within sixty (60) days of the date of the Offer Notice.


                                      -41-
<PAGE>   50
                  8.3      Purchase of Warrants.  In the event the Loans are 
repaid in full on or prior to January 31, 1996, PDGE shall have the option to
repurchase the then unexercised portion of the Warrants for the purchase price
of $100,000. Such option shall be exercised upon written notice to Lender given
concurrent with the repayment in full of the Loans, accompanied by payment in
the amount of $100,000, which shall be received by Lender not later than January
31, 1996.

                  8.4      Refinancing of Murryville, Pennsylvania Property.
Lender hereby agrees that it shall not unreasonably withhold its consent to any
proposed refinancing of the Property provided that (a) all proceeds from the
refinancing shall be used to pay down the Loans, whether or not then due, (b) at
least $400,000 in proceeds are received by Lender from the refinancing; (c)
Lender shall be permitted to maintain a second priority mortgage on the Property
subject to no liens other than the mortgage lien on the refinance lender and
liens for current property taxes not yet payable; (d) no Event of Default or
event or circumstance exists that with the giving of notice or the passage of
time or otherwise would constitute an Event of Default either before or after
giving effect to the proposed refinancing; and (e) the PDGE Debtor Parties and
the refinance lender shall execute and deliver or cause to be executed and
delivered to Lender such mortgages, subordination and intercreditor agreements,
documents and other information as Lender may reasonably require, including a
Lender's policy of title insurance in an amount required by Lender.

         9.       No Further Modification.  No provision hereof can be changed,
waived, discharged or terminated, except by an instrument in writing signed by
the party against whom the enforcement of the change, waiver, discharge or
termination is sought. It is understood that the Lender is under no obligation
to extend the term of any credit extended under this Agreement or any other Loan
Document and any such further modifications or extensions will be made in the
Lender's sole and absolute discretion. Any such modifications or extensions will
be evidenced by the acceptance by Lender of a written agreement having terms
acceptable to the Lender. Each of the PDGE Debtor Parties and Guarantors
acknowledge that all of the terms and all of the obligations of Lender with
respect to any credit of any kind extended to the PDGE Debtor Parties is fully
contained in this Agreement and any other Loan Documents and that no other
understanding, written or oral, has been entered into in connection herewith.

         10.      Release of Lender.  As additional consideration for the
undertaking to execute and deliver this Agreement, the PDGE Debtor Parties and
Guarantors hereby each release and forever discharge the Lender, the Lender's
agents, servants, employees, officers, directors, attorneys, and shareholders,
as well as the respective successors and assigns of any and all thereof
(collectively, the "Released Lender Parties") from all damage, loss, claims,
demands, liabilities, obligations, actions and causes of action whatsoever which
the Debtor Parties or Guarantors, or any of them, might now have or


                                      -42-
<PAGE>   51
claim to have against the Lender, whether presently known or unknown, and of
every nature and extent whatsoever, on account of or in any way concerning,
arising out of or founded on the Integra Loans, PDGE Loans, PDGES Loan or any 
of the Loan Documents or PDGES Loan Documents, including without implied 
limitation, all such loss or damage of any kind heretofore sustained that 
might arise as a consequence from the dealings between the parties.

                  To the extent applicable, the PDGE Debtor Parties and
Guarantors waive the provisions of Section 1542 of the California Civil Code
which provides as follows:

                         "A GENERAL RELEASE DOES NOT
                         EXTEND TO CLAIMS WHICH THE
                         CREDITOR DOES NOT KNOW OR
                         SUSPECT TO EXIST IN HIS FAVOR AT
                         THE TIME OF EXECUTING THE
                         RELEASE, WHICH IF KNOWN BY HIM
                         MUST HAVE MATERIALLY AFFECTED

         11.3     Successors and Assigns.  This Agreement will inure to the
benefit of and bind the respective successors and permitted assigns of the
parties.

         11.4     Attorneys' Fees.  If any legal action or proceeding is brought
by any party in order to enforce a provision of this Agreement or any Loan
Document, the unsuccessful party in such action or proceeding, whether or not
such action or proceeding is prosecuted to final judgement, shall pay all of the
attorneys' fees and costs incurred by the prevailing party.  If any PDGE Debtor
Party or Guarantors shall become the subject of any bankruptcy or insolvency
proceeding, the PDGE Debtor Parties and Guarantors shall pay to the lender on
demand all attorneys' fees, costs and expenses which the Lender may incur (i) to
obtain relief from any bankruptcy or insolvency proceeding which delays or other
wise impairs the Lender's exercise of any right or remedy under this Agreement,
or any of the Loan Documents, or (ii) to obtain adequate protection or assurance
for any of the Lender's rights or collateral.

         11.5       Partial Invalidity.  If any provision of this Agreement is
determined by a court having jurisdiction to be illegal, invalid or
unenforceable under any present or future law, the remainder of this Agreement
will not be affected thereby.  It is the intention of the parties that if any
provision is so held to be illegal, invalid or unenforceable, there will be
added in lieu thereof a provision as similar in terms to such provision as is
possible that is legal, valid and enforceable.

         11.6       Headings.  The headings used in this Agreement are for ease
in reference and are not intended to affect the interpretation of this Agreement
in any way.

         11.7       No Waiver.  No waiver of any action or default by any party
will be implied from the failure or delay by the other party to take any action
in respect of such action or default.  No express waiver of any condition
precedent or default will affect any other default or extend any period of time
for performance other than as specified in such express waiver.  One or more
waivers of any default in the performance of any provision of this Agreement
will not be deemed a waiver of any subsequent default in the performance of the
same provision or any other provision.  The consent to or approval of any act or
request by any party will not be deemed to waive or render unnecessary the
consent to or approval of any subsequent similar act or request.  A party's
exercise of any right or remedy under this Agreement will not preclude any
other or further exercise thereof or the exercise of any other right or remedy.
No course of dealing between the parties will be deemed to amend the terms of
the Agreement or to preclude any party from


                                    -44-


<PAGE>   53
exercising the rights and remedies herein contained notwithstanding such course
of dealing. The rights and remedies provided in this Agreement are cumulative
and no right or remedy will be exclusive or any other, or of any other
right or remedy at law or in equity which any party might otherwise have by
virtue of a default under this Agreement and the exercise of any right or remedy
by any party will not impair such party's standing to exercise any other right
or remedy.

                  11.8     Applicable Law.  The lending transaction contemplated
by this Agreement and the Loan Documents has been negotiated, consummated and is
to be performed in the State of California. This Agreement and the other Loan
Documents described herein shall be governed by, and construed and enforced in
accordance with the substantive law of the State of California. Any action or
proceeding arising in connection with this Agreement and the Loan Documents
shall be brought in a federal or state court within Los Angeles County,
California, and the Debtor Parties and Guarantors hereby consent to the
jurisdiction of any federal or state court within the State of California and
located in State of California and located in Los Angeles County, California. 
The Debtor Parties and Guarantors irrevocably and unconditionally submit to 
the jurisdiction (both subject matter and personal) or each such court and 
irrevocably and unconditionally waive (a) any objection that they might now or 
hereafter have to the venue in any such court; and (b) any claim that any 
action or proceeding brought in any such court has been brought in an 
inconvenient forum. Notwithstanding the foregoing, the Lender may, in its sole 
and absolute discretion, initiate proceedings in the courts of any other 
jurisdiction in which any Debtor Party or Guarantor may be found or in which 
its assets may be located.

                  11.9     JURY WAIVER.  THE PARTIES HEREBY EXPRESSLY WAIVE ANY 
RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (1)
ARISING UNDER THIS AGREEMENT, ANY OF THE LOAN DOCUMENTS DESCRIBED HEREIN OR ANY
OTHER INSTRUMENT, DOCUMENT OR AGREEMENT EXECUTED OR DELIVERED IN CONNECTION
HEREWITH, OR (2) IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE
DEALINGS OF THE PARTIES HERETO OR ANY OF THEM WITH RESPECT TO THIS AGREEMENT,
THE LOAN DOCUMENTS, OR ANY OTHER INSTRUMENT, DOCUMENT OR AGREEMENT EXECUTED OR
DELIVERED IN CONNECTION HEREWITH, OR THE TRANSACTIONS RELATED HERETO OR THERETO,
IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER SOUNDING IN
CONTRACT OR TORT OR OTHERWISE; AND THE PARTIES HEREBY AGREE AND CONSENT THAT ANY
SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL

$2,419,993.71                                         Los Angeles, California
                                                              October 1, 1995


        FOR VALUE RECEIVED, PDG ENVIRONMENTAL, INC., a Delaware corporation; 
PDG, INC., a Pennsylvania corporation; PROJECT DEVELOPMENT GROUP, INC., a 
Pennsylvania corporation; and ENVIRO-TECH ABATEMENT SERVICES CO., a North 
Carolina corporation (collectively, the "Borrower"), jointly and severally 
promise to pay to the order of CVD FINANCIAL CORPORATION, a Delaware 
corporation, its successors and assigns (the "Lender") at 400 Burrard Street, 
Suite 1250, Vancouver, British Columbia, V6C 3A6 Canada, or at such other place 
as might be designated in writing by the Lender, the principal sum of Two 
Million Four Hundred Nineteen Thousand Nine Hundred Ninety Three Dollars and 
71/100 ($2,419,993.71) or so much thereof as has been disbursed by the lender 
and remains unpaid, together with interest thereon at a variable rate equal to 
the Note Rate (as hereafter defined) then in effect. The "Note Rate" shall be 
equal to three percent (3%) in excess of the Prime Rate (as hereafter 
defined) per annum. The Note Rate charged hereunder will change effective on 
the date of each change in the Prime Rate without notice to the Borrower. As 
used in this Note, the term "Prime Rate" means the rate of interest per annum 
most recently announced by Citibank, N.A., New York, New York, for the guidance 
of its officers as its prime lending rate or, if the foregoing index is not 
available, the highest prevailing base interest rate charged on corporate loans 
by large United States money center commercial banks as published from time to 
time in the "Money Rates" column of The Wall Street Journal. The Prime Rate is 
currently eight and three quarters percent (8.75%) per annum and the Borrower 
acknowledges that this Note will bear interest at a rate three percent (3%) in 
excess of eight and three quarters percent (8.75%), or eleven and three 
quarters percent (11.75%) per annum, until the date of a change in the Prime 
Rate. Interest will be calculated on the basis of the actual days elapsed based 
on a per diem charge computed over a year composed of three hundred sixty (360) 
days.

        Principal and interest will be paid as follows: Interest on the amounts 
disbursed, accrued from October 1, 1995 through the last day of each month, 
will be paid on the first day of each succeeding calendar month, commencing on 
November 1, 1995. On December 31, 1996, the entire unpaid principal balance and 
all accrued but unpaid interest thereon will be due and payable.


                                  SCHEDULE "C"
<PAGE>   57
         This Note is issued by the Borrower and accepted by the Lender pursuant
to a certain Amended and Restated Loan Agreement between the Borrower and the
Lender dated as of October 31, 1995, (the "Loan Agreement") and evidences the
Revolving Loan as defined in the Loan Agreement. It is specifically understood
that the aggregate advances made during the term of this Note shall exceed the
face amount of this Note, but the unpaid principal balance of this Note will
never exceed the face amount of this Note. Advances, readvances and payments
under this Note may, at the option of the Lender, be recorded on this Note or by
deposits and withdrawals from an account maintained by the Borrower on deposit
with the Lender or under the control of the Lender, either of which will be
prima facie evidence of such advances, payments and the unpaid balance of this
Note. All advances under this Note will be made by the Lender in accordance with
the terms of the Loan Agreement. All advances under this Note will be made by
the Lender in accordance with the terms of the Loan Agreement.

         Subject to Lender's conversion rights as set forth in the Loan 
Agreement, the Borrower will have the right at any time and from time to time, 
upon not less than fifteen (15) business days notice to Lender to prepay all or 
any portion of the unpaid principal balance of this Note without penalty, but 
with interest accrued to the date of prepayment on the unpaid principal balance 
of the Note. Notwithstanding the foregoing, Borrower shall not be required to 
provide Lender with advance notice of any prepayment received by Lender on or 
prior to January 31, 1996.

         The Borrower agrees that if, and as often as, this Note is placed in 
the hands of an attorney for collection or to defend or enforce any of the 
Lender's rights under this Note, the Loan Documents (as defined in the Loan 
Agreement) or otherwise relating to the indebtedness hereby evidenced, the 
Borrower will pay the Lender's reasonable attorneys' fees, all court costs and 
all other expenses incurred by the Lender in connection therewith. The Lender 
may collect a late charge equal to five percent (5%) of each payment which is 
not received by the Lender within ten (10) days after the due date of such 
payment. Such late charge represents the estimate of reasonable compensation 
for the loss which will be sustained by the Lender arising from the Borrower's 
failure to make timely payments and may be collected without prejudice to the 
rights of the Lender to collect any other amounts arising from the Borrower's 
default in payment or to accelerate the maturity of the indebtedness hereby 
evidenced. In addition to the foregoing late charge, at the option of the 
Lender, after the occurrence of any Event of Default (as defined in the Loan 
Agreement), the unpaid balance of this Note will bear interest at a Default 
Rate which is equal to five percent (5.0%) in excess of the Note Rate (eight 
percent (8.0%) in excess of the Prime Rate) and such interest which has accrued 
will be paid at the time of and as a condition precedent to curing any Event of 
Default (as defined in the Loan Agreement). During the existence of any Event 
of Default, the Lender may apply payments received on any amount due hereunder 
or under the terms of any instrument now or hereafter evi-


                                       2

dencing or securing payment of this indebtedness as the Lender determines from 
time to time.

        Payment of the indebtedness hereby evidenced is secured by certain 
security interests described in the Loan Documents (as defined under the Loan 
Agreement). On the breach by the Borrower of any provision of this Note, or the 
occurrence of any other Event of Default under any one or more of the Loan 
Documents or any other instrument now or hereafter evidencing or securing 
payment of the indebtedness hereby evidenced, and the continuation of such 
Event of Default beyond any applicable cure period, at the option of the 
Lender, the entire indebtedness evidenced by this Note will become immediately 
due, payable and collectible then or thereafter as the Lender might elect, 
regardless of the date of maturity of this Note. Failure by the Lender to 
exercise such option will not constitute a waiver of the right to exercise the 
same on the occurrence of any subsequent Event of Default.

        The makers, endorsers, sureties, guarantors and all other persons who 
might become liable for all or any part of this obligation severally waive 
presentment for payment, protest and notice of nonpayment. Such parties consent 
to any extension of time (whether one or more) of payment hereof, release of 
all or any part of the collateral securing payment hereof or release of any 
party liable for the payment of this obligation. Any such extension or release 
may be made without notice to any such party and without discharging such 
party's liability hereunder. If more than one maker executes this Note, the 
liability of each of the undersigned is and shall be joint and several.

        The lending transaction contemplated by this Note and the Loan 
Documents has been negotiated, consummated and is to be performed in the State 
of California. This Note and the other Loan Documents described herein shall be 
governed by, and construed and enforced in accordance with the substantive law 
of the State of California. Any action or proceeding arising in connection with

                                     (TERM)


$559,990.57                                             Los Angeles, California
                                                                October 1, 1995


        FOR VALUE RECEIVED, PDG ENVIRONMENTAL, INC., a Delaware corporation; 
PDG, INC., a Pennsylvania corporation; PROJECT DEVELOPMENT GROUP, INC., a 
Pennsylvania corporation; and ENVIRO-TECH ABATEMENT SERVICES CO., a North 
Carolina corporation (collectively, the "Borrower"), jointly and severally 
promise to pay to the order of CVD FINANCIAL CORPORATION, a Delaware 
corporation, its successors and assigns (the "Lender") at 400 Burrard Street, 
Suite 1250, Vancouver, British Columbia, Canada V6C 3A6, or at such other place 
as might be designated in writing by the Lender, the principal sum of Five 
Hundred Fifty Nine Thousand Nine Hundred Ninety Dollars and 57/100 
($559,990.57) or so much thereof as has been disbursed by the Lender and 
remains unpaid, together with interest thereon at a variable rate equal to the 
Note Rate (as hereafter defined) then in effect. The "Note Rate" shall be equal 
to three percent (3%) in excess of the Prime Rate (as hereafter defined) 
per annum. The Note Rate charged hereunder will change effective on the date of 
each change in the Prime Rate without notice to the Borrower. As used in this 
Note, the term "Prime Rate" means the rate of interest per annum most recently 
announced by Citibank, N.A., New York, New York, for the guidance of its 
officers as its prime lending rate or, if the foregoing index is not available, 
the highest prevailing base interest rate charged on corporate loans by large 
United States money center commercial banks as published from time to time in 
the "Money Rates" column of The Wall Street Journal. The Prime Rate is 
currently eight and three quarters percent (8.75%) per annum and the Borrower 
acknowledges that this Note will bear interest at a rate three percent (3%) in 
excess of eight and three quarters percent (8.75%), or eleven and three 
quarters percent (11.75%) per annum, until the date of a change in the Prime 
Rate. Interest will be calculated on the basis of the actual days elapsed based 
on a per diem charge computed over a year composed of three hundred sixty (360) 
days.

        Principal and interest will be paid as follows: Interest on the amounts
disbursed, accrued from October 1, 1995 through the last day of each month, will
be paid on the first day of each succeeding calendar month, commencing on
November 1, 1995. The unpaid principal principle balance of the Note will be
paid in consecutive monthly installments of Thirteen Thousand Five Hundred
Thirty Three Dollars ($13,533), payable on the first day of each month beginning
November 1, 1995 with the remaining unpaid principal balance and all accrued 
but unpaid interest thereon being due and payable on December 31, 1996.


                                  SCHEDULE "D"

<PAGE>   62
        This Note is issued by the Borrower and accepted by the Lender pursuant 
to a certain Amended and Restated Loan Agreement between the Borrower and the 
Lender, dated as of October 31, 1995 (the "Loan Agreement") and evidences the 
Term Loan as defined in the Loan Agreement. All advances under this Note will 
be made by the Lender in accordance with the terms of the Loan Agreement.

        Subject to Lender's conversion rights as set forth in the Loan
Agreement, the Borrower will have the right at any time and from time to time,
upon not less than fifteen (15) business days notice to Lender to prepay all or
any portion of the unpaid principle balance of this Note without penalty, but
with interest accrued to the date of prepayment on the unpaid principal balance
of the Note. Notwithstanding the foregoing, Borrower shall not be required to
provide Lender with advance notice of any prepayment received by Lender on or
prior to January 31, 1996.

        The Borrower agrees that if, and as often as, this Note is placed in the
hands of an attorney for collection or to defend or enforce any of the Lender's
rights under this Note, the Loan Documents (as defined in the Loan Agreement) or
otherwise relating to the indebtedness hereby evidenced, the Borrower will pay
the Lender's reasonable attorneys' fees,, all court costs and all other expenses
incurred by the Lender in connection therewith. The Lender may collect a late
charge equal to five percent (5%) of each payment which is not received by the
Lender within ten (10) days after the due date of such payment. Such late charge
represents the estimate of reasonable compensation for the loss which will be
sustained by the Lender arising from the Borrower's failure to make timely
payments and may be collected without prejudice to the rights of the Lender to
collect any other amounts arising from the Borrower's default in payment or to
accelerate the maturity of the indebtedness hereby evidenced. In addition to the
foregoing late charge, at the option of the Lender, after the occurrence of any
Event of Default (as defined in the Loan Agreement), the unpaid balance of this
Note will bear interest at a Default Rate which is equal to five percent (5.0%)
in excess of the Note Rate (eight percent (8.0%) in excess of the Prime Rate)
and such interest which has accrued will be paid at the time of and as a
condition precedent to curing any Event of Default (as defined in the Loan
Agreement). During the existence of any Event of Default, the Lender may apply
payments received on any amount due hereunder or under the terms of any
instrument now hereafter evidencing or securing payment of this indebtedness as
the Lender determines from time to time.

                Payment of the indebtedness hereby evidenced is secured by 
certain security interests described in the Loan Documents (as defined under 
the Loan Agreement). On the breach by the Borrower of any provision of this 
Note, or the occurrence of any other Event of Default under any one or more of 
the Loan Documents or any other instrument now or hereafter evidencing or 
securing payment of the indebtedness hereby evidenced, and the continuation of 
such Event of Default


                                      -2-
<PAGE>   63
beyond any applicable cure period, at the option of the Lender, the entire
indebtedness evidenced by this Note will become immediately due, payable and
collectible then or thereafter as the Lender might elect, regardless of the date
of maturity of this Note. Failure by the Lender to exercise such option will not
constitute a waiver of the right to exercise the same on the occurrence of any
subsequent Event of Default.

        The makers, endorsers, sureties, guarantors and all other persons who 
might become liable for all or any part of this obligation severally waive 
presentment for payment, protest and notice of nonpayment. Such parties consent 
to any extension of time (whether one or more) of payment hereof, release of 
all or any part of the collateral securing payment hereof or release of any 
party liable for the payment of this obligation. Any such extension or release 
may be made without notice to any such party and without discharging such 
party's liability hereunder. If more than one maker executes this Note, the 
liability of each of the undersigned is and shall be joint and several.

        The lending transaction contemplated by this Note and the Loan 
documents has been negotiated, consummated and is to be performed in the State 
of California. This Note and the other Loan Documents described herein shall be 
governed by, and construed and enforced in accordance with the substantive law 
of the State of California. Any action or proceeding arising in connection with 
this Note and the Loan Documents shall be brought in a federal or state court 
within Los Angeles County, California, and the Borrowers hereby consent to the 
jurisdiction of any federal or state court within the State of California and 
located in State of California and located in Los Angeles County, California. 
The Borrowers irrevocably and unconditionally submit to the jurisdiction (both 
subject matter and personal) of each such court and irrevocably and 
unconditionally waive (1) any objection that they might now or hereafter have 
to the venue in any such court; and (2) any claim that any action or proceeding 
brought in any such court has been brought in an inconvenient forum. 
Notwithstanding the foregoing, the Lender may, in its sole and absolute 
discretion, initiate proceedings in the courts of any other jurisdiction in 
which any Borrower may be found or in which its assets may be located.

        THE MAKERS HEREBY EXPRESSLY WAIVE ANY RIGHT TO TRIAL BY JURY OF ANY 
CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (1) ARISING UNDER THIS NOTE, ANY OF 
THE LOAN DOCUMENTS DESCRIBED HEREIN OR ANY OTHER INSTRUMENT, DOCUMENT OR

security interest created hereby are given for the purpose of securing the 
payment and performance of any and all of Pledgor's and the other PDGE Debtor 
Parties' presently existing or hereafter arising obligations and liabilities 
owing to Lender ("Obligations"), including, without implied limitation (i) 
payment of all indebtedness evidenced by that certain Revolving Note in the 
principal amount of $2,419,993.71 and Term Note in the principal amount of 
$559,990.57 (as defined in the Loan Agreement), executed by the PDGE Debtor 
Parties in favor of Lender; (ii) payment and performance of all existing and 
future indebtedness and obligations of the PDGE Debtor Parties to the Lender 
under the Loans and all Loan Documents (as defined in the Loan Agreement); 
(iii) payment and performance of any additional existing or future indebtedness 
or obligations of the PDGE Debtor Parties to the Lender when evidenced by a 
writing or writings reciting that they are so secured; (iv) all present and 
future obligations of Pledgor under this Agreement; and (v) any and all 
amendments, modifications, renewals and/or extensions of any of the foregoing, 
including, but not limited to amendments, modifications, renewals or extensions 
which are evidenced by new or additional instruments, documents or agreements 
or which change the rate of interest on any indebtedness or obligations secured 
hereby. The term "Obligations" as used herein is intended to mean Obligations 
in its most comprehensive sense and includes all present and future 
indebtedness, liabilities, undertakings, covenants and other obligations of the 
PDGE Debtor Parties, whether voluntary or involuntary, absolute or contingent, 
liquidated or unliquidated, determined or undetermined, earned or unearned, and 
due or not due.

        2.      PLEDGE.  Pledgor hereby assigns, grants, pledges and transfers 
to Lender, as security for the payment and performance of the Obligations 
described in Paragraph 1 above, a security interest in, and lien upon all of 
Pledgor's right, title and interest in and to the following:

                (a) the Shares;


                                  SCHEDULE "E"

<PAGE>   83

                  (b) all options or warrants for the purchase of additional
Shares and all rights represented thereby held by Pledgor if any (the
"Options");

                  (c) stock powers ("Powers") duly executed in blank, with such 
signatures properly guaranteed covering all of the Shares; and

                  (d) the proceeds of each of the foregoing including, without 
limitation any and all dividends, cash, instruments and other property from 
time to time received, receivable, or otherwise distributed in respect of or in 
exchange for any of the Shares or Options (the "Proceeds"). The Shares, the 
Options, the Powers, and the Proceeds shall be collectively referred to as the
"Collateral".

         3.  DELIVERIES.  Concurrent with the execution hereof, Pledgor has 
delivered Certificate(s) No(s).___________________, representing all of the 
Shares, to Lender together with related Powers or endorsements, to be held 
pursuant to the terms hereof for the benefit of Lender.

         4.  LENDER'S DUTIES.  Lender shall have no duty with respect to the 
Collateral other than the duty to use reasonable care if it is in its 
possession. Without limiting the generality of the foregoing, Lender shall be 
under no obligation to take any steps necessary to preserve rights in the 
Collateral against any other parties, to sell same if it threatens to decline 
in value, or to exercise any rights represented thereby; provided, however, 
that Lender may, at its option, do so, and any and all expenses incurred in 
connection therewith shall be for the sole account of Pledgor.

         5.  VOTING RIGHTS; DIVIDENDS; ETC.  During the term of this Agreement 
and as long as no Event of Default, as defined in the Loan Modification 
Agreement or other Loan Documents (an "Event of Default"), shall have occurred 
and be continuing beyond any applicable cure period:

                  (a) Pledgor shall be entitled to exercise any and all voting 
and other consensual rights pertaining to the Shares or any part thereof for 
any purpose not inconsistent with the terms of this Agreement, the Loan 
Modification Agreement or the other Loan Documents.

                  (b) Pledgor shall be entitled to receive and retain any and 
all dividends and distributions paid in respect of the Shares provided, 
however, that any and all

                           (i) dividends and distributions paid or payable other
than in cash in respect of, and instruments and other property received,
receivable or otherwise distributed in respect of, or in exchange for, any
Shares,


                                      -2-


<PAGE>   84
                    (ii)  dividends and distributions paid or payable in cash in
respect of any Shares in connection with a partial or total liquidation or
dissolution or in connection with a reduction of capital, capital surplus or
paid-in surplus, and

                    (iii) cash paid with respect to, payable or otherwise 
distributed on redemption of, or in exchange for, any Shares, shall be 
forthwith delivered to Lender to hold as Collateral and shall, if received by 
Pledgor, be received in trust for the benefit of Lender, be segregated from the 
other property or funds of Pledgor, and be forthwith delivered to Lender as 
Collateral in the same form as so received (with any necessary endorsement).

                (c) Lender shall execute and deliver (or cause to be executed 
and delivered) to Pledgor all such proxies and other instruments as Pledgor may 
reasonably request for the purpose of enabling Pledgor to exercise those voting 
and other rights which it is entitled to exercise pursuant to paragraph 5(a) 
above and to receive those dividends or distributions which it is authorized to 
receive and retain pursuant to paragraph 4(b) above.

                (d) If an Event of Default shall have occurred and be continuing
and any amounts shall be due and payable (whether by acceleration, maturity, or
otherwise) under any of the Obligations, all rights of Pledgor to exercise the
voting and other consensual rights which it would otherwise be entitled to
exercise pursuant to this paragraph 4 and to receive the dividends and 
distributions which it would otherwise be authorized to receive and retain
pursuant to this paragraph shall, at Lender's option, cease, and all such rights
shall, at Lender's option, thereupon become vested in Lender so long as an Event
of Default shall continue, and Lender shall, at its option, thereupon have the
sole right to exercise such voting and other consensual rights and to receive
and hold as Collateral such dividends and interest payments.

        6.      REPRESENTATIONS. Pledgor warrants, represents and covenants
that:

                (a) except as set forth in the Securities Act of 1933, as 
amended (the "Act"), there are no restrictions upon the transfer of any of the 
Collateral and Pledgor has the right to pledge and grant a security interest in 
or otherwise transfer such Collateral free of any encumbrances or rights of 
third parties;

                (b) all of the Collateral is and shall remain free from all 
liens, claims, encumbrances, and purchase money or other security interests, 
and Pledgor shall not, without Lender's prior written consent, sell, transfer 
or otherwise dispose of any or all of the Collateral;

                (c) this Agreement, and the delivery to Lender of the 
certificates representing the Shares creates a valid and perfected security 
interest in the Collateral in favor of Lender, and all actions necessary or 
desirable to such perfection have been duly taken;

                (d) no authorization or other action by, and no notice to or 
filing with, any governmental authority or regulatory body is required either 
(i) for the grant by Pledgor of the security interest granted hereby or for the 
execution, delivery or performance of this


                                      -3-

<PAGE>   85
Agreement by Pledgor; (ii) for the perfection of or exercise by Lender of its 
rights and remedies hereunder; or (iii) for the exercise by Lender of the 
voting or other rights provided for in this Agreement or the remedies in 
respect of the Shares pursuant to this Agreement (except as may be required in 
connection with a disposition of the Shares by laws affecting the offering and 
sale of securities generally);

                (e)  Pledgor has made its own arrangements for keeping informed 
of changes or potential changes affecting the Collateral (including, but not 
limited to, rights to convert, rights to subscribe, payment of dividends, 
reorganization or other exchanges, tender offers and voting rights) and Pledgor 
agrees that Lender shall have no responsibility or liability for informing 
Pledgor of any such changes or potential changes or for taking any action or 
omitting to take any action with respect thereto;

                (f)  The Shares represent 59.5% of the total issued and 
outstanding shares of the common stock of Remediation and constitute all shares 
of Remediation owned by Pledgor or any PDGE Debtor Party or Affiliate thereof 
(as defined in the Loan Modification Agreement);

                (h)  All of the outstanding Shares have been duly and validly 
issued by Remediation and they are fully paid and nonassessable; and

                (i)  All of the Shares have been registered under the 
Securities Act of 1933, as amended, and shall at all times be the subject of a 
current effective registration statement and prospectus, and subject to no 
restrictions on resale by Lender except as set forth in the Act.

        7.      SHARE ADJUSTMENT. In the event that during the term of this 
Agreement, any reclassification, readjustment or other change is declared or 
made in the capital structure of Borrower, or any Option is exercised, all new 
substituted and additional shares, options, or other securities, issued, or 
issuable, to Pledgor by reason of any such change or exercise shall be 
delivered to and held by Lender under the terms of this Agreement in the same 
manner as the Collateral originally pledged hereunder.

         8.      WARRANTS.  In the event that during the term of this Agreement,
subscription warrants or any other rights or options shall be issued or
exercised in connection with the Collateral, such warrants, rights and options,
acquired by Pledgor shall be immediately assigned by Pledgor to Lender and all
new stock or other securities so acquired by Pledgor shall also be immediately
assigned to Lender to be held under the terms of this Agreement in the same
manner as the Collateral originally pledged hereunder.

         9.      CONSENT.  Pledgor hereby consents that, from time-to-time,
before or after the occurrence or existence of any Event of Default, with or
without notice to or assent from Pledgor, any other security at any time held by
or available to Lender of any of the Obligations or any other security at any
time held by or available to Lender of any other person, firm or corporation
secondarily or otherwise liable for any of the Obligations, may be exchanged,


                                      -4-
<PAGE>   86

surrendered, or released and any of the Obligations may be changed, altered, 
renewed, extended, continued, surrendered, compromised, waived or released, in 
whole or in part, as Lender may see fit, and Pledgor shall remain bound under 
this Agreement notwithstanding any such exchange, surrender, release, 
alteration, renewal, extension, continuance, compromise, waiver or inaction, or 
extension of further credit.

         10.  REMEDIES UPON DEFAULT.  Upon the occurrence of an Event of 
Default, Lender shall have, in addition to any other rights given by law or the 
rights hereunder, all of the rights and remedies with respect to the Collateral 
of a secured party under the California Uniform Commercial Code ("Code").

         In addition, with respect to the Collateral, or any part thereof, upon 
ten (10) business days' notice to Pledgor following the occurrence of an Event 
of Default and Pledgor's failure to cause such Event of Default to be cured 
within such period, Lender may sell or cause the same to be sold at any public 
or private sale, in one or more sales or lots, at such price as Lender may deem 
best, and for cash or on credit or for future delivery, without assumption of 
any credit risk, and the purchaser of any or all of the Collateral so sold 
shall thereafter hold the same absolutely, free from any claim, encumbrance or 
right of any kind whatsoever.

         Any sale of the Collateral conducted in conformity with reasonable 
commercial practices of banks, insurance companies or other financial 
institutions disposing of property similar to the Collateral and any sale made 
through NASDAQ, any securities exchange or any NASD member shall be 
conclusively deemed to be commercially reasonable.  Any requirements of 
reasonable notice shall be met if such notice is mailed to Pledgor, at the 
address set forth in the Loan Agreement, at least ten (10) calendar days before 
the time of the sale or disposition.  Any other retirement of notice, demand or 
advertisement for sale, is, to the extent permitted by law, waived.

         Lender may, in its own name, or in the name of a designee or nominee, 
buy at any public sale of the Collateral, or to the extent permitted by the 
Code, at any private sale.  Lender shall have the right to execute any document 
or form, in its name or in the name of the Pledgor, which may be necessary or 
desirable in connection with such sale of Collateral.

         In addition to specific rights provided herein with respect to sales 
of the Shares, and subject to applicable law, sales of the Collateral may be 
conducted with or without demand and with or without notice or advertisement, 
for cash, credit or for future delivery, all as the Lender shall deem 
appropriate.  Without limiting the foregoing, the Lender may (i) approach and 
negotiate with potential purchasers, and (ii) restrict the prospective bidders 
or purchasers to persons who will represent and agree that they are purchasing 
such Collateral for their own account for investment and not with a view to the 
distribution or resale thereof.  In the event any such Collateral is sold at 
private sale, Pledgor agrees that such sale shall not, by reason merely that it 
is a private sale subject to the potential restrictions described herein, or 
that there is a possibility that a substantially higher price might have been 
realized at a public sale, be deemed to have not been made in a commercially 
reasonable manner.  Pledgor recognizes that no ready 




                                      -5-

<PAGE>   87
market may exist for such Collateral and that a sale by Lender of any such
Collateral for an amount substantially less than the value of the Shares may be
commercially reasonable in view of the difficulties that may be encountered in
attempting to sell a large block of the securities of Remediation.  Upon
consummation of any such sale, Lender shall have the right to assign, transfer
and deliver to the purchaser or purchasers thereof, the Collateral so sold. Each
such Purchaser of any such sale shall hold the Property sold absolutely free
from any claim or right on the part of the Pledgor, and Pledgor hereby waives
(to the extent permitted by law) all rights of redemption, stay and/or appraisal
which Pledgor now has or may at any time in the future have under any rule of
law or statute now existing or hereafter enacted.  If any consent, approval or
authorization of any state, municipal or other governmental agency or authority
shall be necessary to effectuate any sale or disposition of the Collateral,
Pledgor shall execute all such applications and other instruments as may be
required in connection with securing any such consent, approval or authorization
and, will otherwise use its best efforts to secure the same. Under no
circumstances will Lender be obligated to register any securities under the
Securities Act of 1933 or any similar qualification or registration law of any
state, unless, in its sole discretion, it shall elect to do so, in which case
the cost of such registration and qualification shall become part of the
Obligations secured hereby.

         11.  RELEASE OF SHARES BY LENDER.  Provided that an Event of Default 
(as defined in the Loan Agreement or other Loan Documents) has not then 
occurred and be continuing beyond any applicable cure period, Lender agrees to 
permit Pledgor to arrange for the sale (a "Pledgor Arranged Sale"), from time 
to time, of all or a portion of the Shares in the event (i) all proceeds of 
such sale, net of all brokerage commissions and related costs of sale ("Net 
Sales Proceeds") are paid to Lender to be applied to the Obligations, whether 
or not then due; (ii) such Pledgor Arranged Sale is made at a price per share 
not less than the average closing price for shares of Remediation for the 
twenty (20) trading days immediately preceding such sale as reported on NASDAQ 
or any securities exchange on which the Remediation common stock is then listed 
(the "Minimum Price"); and (iii) if the Net Sales Proceeds to be realized are 
less than $1.50 per Share, Lender shall be given a right of first refusal to 
purchase such Shares at the Minimum Price.  Pledgor shall give Lender notice of 
the number of Shares ("Subject Shares") to be covered by each proposed Pledgor 
Arranged Sale, the identity of the purchaser (if known), the Minimum Price 
applicable thereto, the anticipated Net Sales Proceeds, and, if the Net Sales 
Proceeds are anticipated to be less than $1.50 per share, an offer to sell such 
Shares to Lender at the Minimum Price, which offer Lender shall accept or 
reject by written notice to Pledgor within three (3) business days.  In no 
event shall Lender be required to release the Subject Shares other than to the 
purchaser thereof against receipt of immediate cash payment therefor.  In the 
event Lender shall purchase Subject Shares, the purchase price therefor shall 
be credited by Lender first to expenses of collection and other charges then 
due and owing under the Loan Documents; second to interest due on the Revolving 
Loan, Term Loan and other Obligations; and third to principal and any other 
Obligations. 

         12.  LENDER AS PLEDGOR'S ATTORNEY-IN-FACT.  Pledgor hereby irrevocably 
appoints Lender as its attorney-in-fact to arrange for the transfer at any time 
of the Collateral on the books of Pledgor to the name of Lender or to the name 
of Lender's nominee.





                                      -6-
<PAGE>   88
         13.  FURTHER ASSURANCES.  Pledgor agrees that it will cooperate with 
Lender and will execute and deliver, or cause to be executed and delivered, all 
such other stock powers, proxies, instruments, and documents and will take all 
such other action, as Lender may reasonably request from time in order to carry 
out the provisions and purposes hereof.

         14.  ATTORNEYS' FEES AND COSTS.  Pledgor hereby agrees to pay all 
reasonable attorneys' fees and all other costs and expenses which may be 
incurred by Lender in the enforcement of this Agreement, whether or not suit is 
brought. 

         15.  NOTICES.  All notices or demands by any party hereto to the other 
party and relating to this Agreement shall be made in the manner and to the 
addresses set forth in the Loan Modification Agreement.

         16.  CALIFORNIA LAW APPLICABLE.  This Agreement shall be governed by, 
and construed in accordance with, the Laws of the State of California.

         17.  GENERAL PROVISIONS.

                  (a)  This Agreement shall be binding and deemed effective 
when executed by Pledgor and accepted and executed by Lender.

                  (b)  This Agreement shall bind and inure to the benefit of 
the respective successors and assigns of Pledgor and Lender; provided, however, 
that Pledgor may not assign this Agreement or any rights hereunder without 
Lender's prior written consent and any prohibited assignment shall be 
absolutely void.  No consent to an assignment by Lender shall release Pledgor 
from its obligations to Lender hereunder.  Lender may assign its rights and 
duties hereunder.  Lender reserves the right to sell, assign, transfer, 
negotiate, or grant participations in all or any part of, or any interest in 
rights and benefits hereunder.  In connection therewith, Lender may disclose 
all documents and information which Lender now or hereafter may have relating 
to Pledgor or Pledgor's business.

                  (c)  Section headings and numbers have been set forth herein 
for convenience only.  Unless the contrary is compelled by the context, 
everything contained in each Section hereof applies equally to this entire 
Agreement. 

                  (d)  Neither this Agreement nor any uncertainty or ambiguity 
herein shall be construed or resolved against Lender or Pledgor, whether under 
any rule of construction or otherwise, by virtue of such party's having 
prepared the same.  On the contrary, this Agreement has been reviewed by each 
of the parties and their counsel and shall be construed and interpreted 
according to the ordinary meaning of the words used so as to fairly accomplish 
the purposes and intentions of all parties hereto.

                              AMENDED AND RESTATED
                             STOCK PURCHASE WARRANT

                RIGHT TO PURCHASE 277,500 SHARES OF COMMON STOCK
                                       OF
                            PDG ENVIRONMENTAL, INC.


         THIS CERTIFIES THAT CVD FINANCIAL CORPORATION ("Holder") is entitled 
to purchase, on or before August 31, 1998, Two Hundred Seventy Seven Thousand 
Five Hundred (277,500) shares of the common stock ("Common Stock") of PDG 
ENVIRONMENTAL, INC., a Delaware corporation (the "Corporation") upon exercise 
of this Warrant along with presentation of the full purchase price.  The 
purchase price of the common stock is equal to One and 125/100 Dollars ($1.125) 
per share (the "Exercise Price").  This Warrant is granted to Holder in 
consideration of Holder's execution and delivery of that certain Loan 
Modification Agreement, of even date herewith, between Holder, on the one hand, 
and the Corporation and PDG, INC., a Pennsylvania corporation; PROJECT 
DEVELOPMENT GROUP, INC., a Pennsylvania corporation; and ENVIRO-TECH ABATEMENT 
SERVICES CO., on the other hand.  This Warrant amends and restates in its 
entirety the 227,500 share Warrant issued to Holder dated March 23, 1994.

         This Warrant may be exercised in whole or in part at any time and from 
time to time on or before August 31, 1998, by the Holder's presentation or 
surrender of this Warrant to the Corporation accompanied by payment of the 
aggregate Exercise Price for the shares as to which it is being exercised, or a 
statement that the aggregate Exercise Price is being credited against amounts 
due or to become due to Lender under the Loan Agreement, and instructions for 
delivery of the certificates representing the shares purchased.  In the event 
the Warrant is exercised in part only, the Corporation shall immediately issue 
and deliver to Holder a new Warrant, having the same terms and conditions as 
this Warrant, evidencing the right of Holder to purchase the number of shares 
as to which this Warrant has not bee exercised.

                  1.  Adjustment of Exercise Price and Number of Shares 
Deliverable Upon Exercise of Warrant.  The Exercise Price and the number of 
Shares purchasable upon the exercise of this Warrant are subject to adjustment 
from time to time upon the occurrence of the events enumerated in this 
paragraph.

                           (a)  In case the Corporation shall at any time after 
the date of this Warrant:




                                  SCHEDULE "H"

<PAGE>   91

                                    (i) Pay a dividend of its shares of its 
Common Stock or make a distribution in shares of its Common Stock with respect 
to its outstanding Common Stock;

                                    (ii) Subdivide its outstanding shares of 
Common Stock;

                                    (iii) Combine its outstanding shares of 
Common Stock; or

                                    (iv) Issue any other shares of capital 
stock by reclassification of its shares of Common Stock, the Exercise Price in 
effect at the time of the record date of such dividend, subdivision, 
combination, or reclassification shall be proportionately adjusted so that 
Holder shall be entitled to receive the aggregate number and kind of shares 
which, if this Warrant had been exercised prior to such event, Holder would 
have owned upon such exercise and been entitled to receive by virtue of such 
dividend, subdivision, combination, or reclassification.

Such adjustment shall be made successively whenever any event listed above 
shall occur.

                           (b) In case the Corporation shall fix a record date 
for the issuance of rights, options, or warrants or make a distribution of 
shares of Common Stock to all (but not less than all) holders of its 
outstanding Common Stock entitling them to subscribe for or purchase shares of 
Common Stock (or securities convertible into shares of Common Stock) at a price 
per share (or having a conversion price per share, if a security convertible 
into Common Stock) less than the market price of the shares (based on the 
closing price on the record date on NASDAQ or a listed securities exchange of 
the Corporation's Common Stock, or if no such quote is available, the 
shareholders equity on the date of the last financial statement divided by the 
total number of shares outstanding) (the "Market Price"), the Exercise Price to 
be in effect after such record date shall be determined by multiplying the then 
current Exercise Price in effect immediately prior to such record date by a 
fraction, of which the numerator shall be the number of shares of Common Stock 
outstanding on such record date plus the number of shares of Common Stock which 
the aggregate offering price of the total number of shares of Common Stock so 
to be offered (or the aggregate initial conversion price of the convertible 
securities so to be offered) would purchase at such Market Price and of which 
the denominator shall be the number of shares of Common Stock outstanding on 
such record date plus the number of additional shares of Common Stock to be 
offered for subscription or purchase (or into which the convertible securities 
so to be offered are initially convertible).  Such adjustment shall be made 
successively whenever such a record date is fixed; and in the event that such 
rights or warrants are not so issued, the Exercise Price shall again be 
adjusted to be the Exercise Price which would then be in effect if such record 
date had not been fixed.

                           (c)  In case of any reorganization of the
Corporation, or in case of any reclassification or change of outstanding Common
Stock issuable upon exercise of this Warrant (other than a change in par value,
or from par value to no par value, or from no par value to par value, or as a
result of a subdivision or split-up or combination of the Common Stock), or in
case of any consolidation or merger of the Company with or into another entity
(other than a consolidation or merger with a subsidiary or a continuing
corporation), or in case of any sale or conveyance to another entity of all or
substantially all of the property of the Corporation, then, as a condition of
such reorganization, reclassification, change, consolidation, merger, sale, or
conveyance, the Corporation or such successor or purchasing entity, as the case
may be, shall forthwith provide to Holder a supplemental warrant (the
"Supplemental Warrant") which will make lawful and adequate provision whereby
Holder shall have the right thereafter to receive, upon exercise of such
Supplemental Warrant, the kind and amount of shares and other securities and
property which would have been received upon such reorganization,
reclassification, change, consolidation, merger, sale, or conveyance by a holder
of a number of shares of Common Stock equal to the number of Shares issuable
upon exercise of this Warrant immediately prior to such reorganization,
reclassification, change, consolidation, merger, sale, or conveyance.  Such
Supplemental Warrant shall include provision for adjustments which shall be as
nearly equivalent as may be practicable to the adjustments provided for in this
paragraph.  The above provisions of this paragraph shall similarly apply to
successive reorganizations, reclassifications, and changes of Common Stock and
to successive consolidations, mergers, sales, or conveyances.

                  2.  Registration Rights.

                           (a)  Subject to the provisions of Paragraph 2(b),
below, at any time prior to August 31, 1998, Holder may make a written demand on
the Corporation for registration (a "Demand Registration") under the Securities
Act of 1933, as amended (the "Act") of all or a part of the shares purchased or
purchasable upon the exercise of this Warrant (the "Registrable Shares"). Holder
shall be entitled to one Demand Registration only.  Upon receipt of a Demand
Registration, the Corporation shall take such steps as may be reasonably
necessary to register such securities under the Act as promptly as possible,
including the preparation and filing of a registration statement ("Registration
Statement") with the Securities Exchange Commission and all necessary amendments
thereto, such registration to take effect not later than sixty (60) days
following the date of Holder's demand.  In addition, the Corporation shall take
such actions as may be necessary to register or qualify the Registrable Shares
for sale in such states and jurisdictions as Holder may direct on or prior to
the effective date of such Registration Statement under any local securities or
"blue sky" laws.  All costs or expenses incident to the registration,
qualification or listing of such securities shall be paid by the Corporation,
and the Corporation shall comply with all reasonable requests of Holder made in
connection with the registration, qualification, listing or 




                                       3
<PAGE>   93
sale of Registrable Shares.  Without the prior written consent of Holder, the
Corporation shall not effect any public sale or distribution of its debt or
equity securities during the ten (10)-day period prior to, or during the ninety
(90)-day period beginning on, the effective date of any Registration Statement
covering any Registrable Shares which are the subject of the Demand
Registration.

                           (b)  Notwithstanding the foregoing, the Corporation
shall be entitled to defer the filing of a Registration Statement required by
Demand Registration for a period not to exceed sixty (60) days after receipt of
such demand if: (i) the Corporation is contemplating an underwritten public
offering of its securities and, in the judgment of the managing underwriter
thereof, such filing of the Registration Statement for the Demand Registration
would have a material adverse effect on the Corporation's contemplated offering;
(ii) the Corporation is in possession of material information that it deems
advisable not to disclose in a Registration Statement, provided that such
information is revealed to Holder and Holder agrees with the Corporation's
decision not to disclose such information; or (iii) the Corporation is
prohibited (pursuant to the terms of an underwriting agreement previously
approved by the Holder in connection with a public offering of its securities
effected within the past six (6) months) from filing such Registration
Statement.

                           (c)  Holder shall also have the right, at any time 
and from time to time until August 31, 1998, to include Registrable Shares 
within any Registration Statement of the Corporation filed by the Corporation 
covering shares of its Common Stock other than a Registration Statement filed 
solely with respect to any employee benefit plan of the Corporation (and 
provided that the form of Registration Statement is a type on which the 
Registrable Shares can be registered). The Corporation shall promptly give 
written notice to Holder of any intended registration of its Common Stock not 
less than forty-five (45) days prior to the anticipated effective date of the 
Registration Statement, and Holder shall, within fifteen (15) days of receipt 
thereof, notify the Corporation of the number of Registrable Shares it desires 
to include in the Registration Statement.  Subject to the approval of the 
Corporation's managing underwriter, the Holder shall be entitled to include up 
to all of its Registrable Shares, at its election, within the first 
Registration Statement filed by the Corporation following the date hereof.  The 
number of Registrable Shares which may be included by the Holder in any such 
Registration Statement may be restricted by the Corporation if, in the opinion 
of the Corporation's managing underwriter, the number of shares proposed to be 
sold by the Holder and by the Corporation in such offering exceeds the number 
of securities which can be sold in such offering.  In such event, the 
Corporation shall include in the Registration Statement first the shares 
offered by the Corporation, and then to the extent approved for inclusion 
therein by the Corporation and its managing underwriter, that number of 
Registrable Shares so approved pro rata with any other shares of the 
Corporation's common stock, the holders of which have duly exercised 
registration rights of the type similar to this Paragraph 2(c).  All costs or 
expenses,




                                       4

<PAGE>   94

incident to the registration, qualification or listing of such securities shall 
be paid by the Corporation, and the Corporation shall comply with all 
reasonable requests of Holder made in connection with the registration, 
qualification, listing or sale of Registrable Shares.

                           (d)  Prior to August 31, 1998, the Corporation shall 
not grant any registration rights superior to those provided to the Holder 
hereof without the prior written consent of the Holder.

                  3.  Arbitration.  In the event that a dispute arises between
the Corporation and the holder of this Warrant as to any matter relating to this
Warrant, the matter shall be settled by arbitration in Los Angeles County,
California in accordance with the Rules of the American Arbitration Association
and the award rendered by such arbitrator(s) shall not be subject to appeal and
may be entered in any federal or state court located in Los Angeles County
having jurisdiction thereof, and actions or proceedings shall be brought in no
other forum or venue.

         IN WITNESS WHEREOF, the Corporation has caused this Warrant to be 
executed by its duly authorized officers effective as of the 31st day of 
October, 1995.

                             STOCK PURCHASE WARRANT

                RIGHT TO PURCHASE 375,000 SHARES OF COMMON STOCK


         THIS CERTIFIES that CVD FINANCIAL CORPORATION ("Holder") is entitled 
to purchase, on or before August 31, 1998, three hundred seventy-five (375,000) 
shares of the common stock ("Common Stock") of PDG ENVIRONMENTAL, INC. (the 
"Corporation") upon exercise of this Warrant along with presentation of the 
full purchase price.  The purchase price of the common stock is equal to One 
and 25/100 Dollars ($1.25) per share (the "Exercise Price").  This Warrant is 
granted to Holder in consideration of Holder's execution and delivery of that 
certain Amended and Restated Loan Agreement, of even date herewith, between 
Holder on the one hand, and the Corporation and PDG, INC., a Pennsylvania 
corporation; PROJECT DEVELOPMENT GROUP, INC., a Pennsylvania corporation; and 
ENVIRO-TECH ABATEMENT SERVICES CO., a North Carolina corporation, on the other 
hand.  This Warrant amends and restates in its entirely the 375,000 share 
Warrant issued to Holder dated October 28, 1993, as amended on September 30, 
1994. 

         This Warrant may be exercised in whole or in part at any time and from 
time to time on or before August 31, 1998, by the Holder's presentation or 
surrender of this Warrant to the Corporation accompanied by payment of the 
aggregate Exercise Price for the shares as to which it is being exercised, or a 
statement that the aggregate Exercise Price is being credited against amounts 
due or to become due to Lender under the Loan Agreement, and instructions for 
delivery of the certificates representing the shares purchased.  In the event 
the Warrant is exercised in part only, the Corporation shall immediately issue 
and deliver to Holder a new Warrant, having the same terms and conditions as 
this Warrant, evidencing the right of Holder to purchase the number of shares 
as to which this Warrant has not been exercised.

         1.  Adjustment of Exercise Price and Number of Shares Deliverable Upon 
Exercise of Warrant.  The Exercise Price and the number of Shares purchasable 
upon the exercise of this Warrant are subject to adjustment from time to time 
upon the occurrence of the events enumerated in this paragraph.

                  (a)  In case the Corporation shall at any time after the date 
of this Warrant:

                           (i)  Pay a dividend of its shares of its Common 
Stock or make a distribution in shares of its Common Stock with respect to its 
outstanding Common Stock;

                           (ii)  Subdivide its outstanding shares of Common 
Stock; 

                           (iii)  Combine its outstanding shares of Common 
Stock; or




                                  SCHEDULE "G"

<PAGE>   96
                           (iv)  Issue any other shares of capital stock by 
reclassification of its shares of Common Stock, the Exercise Price in effect at 
the time of the record date of such dividend, subdivision, combination, or 
reclassification shall be proportionately adjusted so that Holder shall be 
entitled to receive the aggregate number and kind of shares which, if this 
Warrant had been exercised prior to such event, Holder would have owned upon 
such exercise and been entitled to receive by virtue of such dividend, 
subdivision, combination, or reclassification.

Such adjustment shall be made successively whenever any event listed above 
shall occur.

                  (b)  In case the Corporation shall fix a record date for the
issuance of rights, options, or warrants or make a distribution of shares of
Common Stock to all (but not less than all) holders of its outstanding Common
Stock entitling them to subscribe for or purchase shares of Common Stock (or
securities convertible into shares of Common Stock) at a price per share (or
having a conversion price per share, if a security convertible into Common
Stock) less than the market price of the shares (based on the closing price on
the record date on NASDAQ or a listed securities exchange of the Corporation's
Common Stock, or if no such quote is available, the shareholders equity on the
date of the last financial statement divided by the total number of shares
outstanding) (the "Market Price"), the Exercise Price to be in effect after such
record date shall be determined by multiplying the then current Exercise Price
in effect immediately prior to such record date by a fraction, of which the
numerator shall be the number of shares of Common Stock outstanding on such
record date plus the number of shares of Common Stock which the aggregate
offering price of the total number of shares of Common Stock so to be offered
(or the aggregate initial conversion price of the convertible securities so to
be offered) would purchase at such Market Price and of which the denominator
shall be the number of shares of Common Stock outstanding on such record date
plus the number of additional shares of Common Stock to be offered for
subscription or purchase (or into which the convertible securities so to be
offered are initially convertible).  Such adjustment shall be made successively
whenever such a record date is fixed; and in the event that such rights or
warrants are not so issued, the Exercise Price shall again be adjusted to be the
Exercise Price which would then be in effect if such record date had not been
fixed.

                  (c)  In case of any reorganization of the Corporation, or in
case of any reclassification or change of outstanding Common Stock issuable upon
exercise of this Warrant (other than a change in par value, or from par value to
no par value, or from no par value to par value, or as a result of a subdivision
or split-up or combination of the Common Stock), or in case of any consolidation
or merger of the Company with or into another entity (other than a consolidation
or merger with a subsidiary or a continuing corporation), or in case of any sale
or conveyance to another entity of all or substantially all of the property of
the Corporation, then, as a condition of such reorganization, reclassification,
change, consolidation, merger, sale, or conveyance, the Corporation or such
successor or purchasing entity, as the case may be, shall forthwith provide to
Holder a supplemental warrant (the "Supplemental Warrant") which will make
lawful and adequate provision whereby Holder shall have the right thereafter to
receive, upon exercise of such




                                      -2-
<PAGE>   97

Supplemental Warrant, the kind and amount of shares and other securities and 
property which would have been received upon such reorganization, 
reclassification, change, consolidation, merger, sale, or conveyance by a 
holder of a number of shares of Common Stock equal to the number of Shares 
issuable upon exercise of this Warrant immediately prior to such 
reorganization, reclassification, change, consolidation, merger, sale, or 
conveyance.  Such Supplemental Warrant shall include provision for adjustments 
which shall be as nearly equivalent as may be practicable to the adjustments 
provided for in this paragraph.  The above provisions of this paragraph shall 
similarly apply to successive reorganizations, reclassifications, and changes 
of Common Stock and to successive consolidations, mergers, sales, or 
conveyances.

         2.  Registration Rights.

                  (a)  Subject to the provisions of Paragraph 2(b), below, at 
any time prior to August 31, 1998, Holder may make a written demand on the 
Corporation for registration (a "Demand Registration") under the Securities Act 
of 1933, as amended (the "Act") of all or a part of the shares purchased or 
purchasable upon the exercise of this Warrant (the "Registrable Shares").  
Holder shall be entitled to one Demand Registration only.  Upon receipt of a 
Demand Registration, the Corporation shall take such steps as may be reasonably 
necessary to register such securities under the Act as promptly as possible, 
including the preparation and filing of a registration statement ("Registration 
Statement") with the Securities Exchange Commission and all necessary 
amendments thereto, such registration to take effect not later than sixty (60) 
days following the date of Holder's demand.  In addition, the Corporation shall 
take such actions as may be necessary to register or qualify the Registrable 
Shares for sale in such states and jurisdictions as Holder may direct on or 
prior to the effective date of such Registration Statement under any local 
securities or "blue sky" laws.  All costs or expenses incident to the 
registration, qualification or listing of such securities shall be paid by the 
Corporation, and the Corporation shall comply with all reasonable requests of 
Holder made in connection with the registration, qualification, listing or sale 
of Registrable Shares.  Without the prior written consent of Holder, the 
Corporation shall not effect any public sale or distribution of its debt or 
equity securities during the ten (10)-day period prior to, or during the ninety 
(90)-day period beginning on, the effective date of any Registration Statement 
covering any Registrable Shares which are the subject of the Demand 
Registration.

                  (b)  Notwithstanding the foregoing, the Corporation shall be 
entitled to defer the filing of a Registration Statement required by Demand 
Registration for a period not to exceed sixty (60) days after receipt of such 
demand if: (i) the Corporation is contemplating an underwritten public offering 
of its securities and, in the judgment of the managing underwriter thereof, 
such filing of the Registration Statement for the Demand Registration would 
have a material adverse effect on the Corporation's contemplated offering; 
(ii) the Corporation is in possession of material information that it deems 
advisable not to disclose in a Registration Statement, provided that such 
information is revealed to Holder and Holder agrees with the Corporation's 
decision not to disclose such




                                      -3-

<PAGE>   98

information; or (iii) the Corporation is prohibited (pursuant to the terms of 
an underwriting agreement previously approved by the Holder in connection with 
a public offering of its securities effected within the past six (6) months) 
from filing such Registration Statement.

                  (c)  Holder shall also have the right, at any time and from 
time to time until August 31, 1998, to include Registrable Shares within any 
Registration Statement of the Corporation filed by the Corporation covering 
shares of its Common Stock other than a Registration Statement filed solely 
with respect to any employee benefit plan of the Corporation (and provided that 
the form of Registration Statement is a type on which the Registrable Shares 
can be registered).  The Corporation shall promptly give written notice to 
Holder of any intended registration of its Common Stock not less than 
forty-five (45) days prior to the anticipated effective date of the 
Registration Statement, and Holder shall, within fifteen (15) days of receipt 
thereof, notify the Corporation of the number of Registrable Shares it desires 
to include in the Registration Statement.  Subject to the approval of the 
Corporation's managing underwriter, the Holder shall be entitled to include up 
to all of its Registrable Shares, at its election, within the first 
Registration Statement filed by the Corporation following the date hereof.  The 
number of Registrable Shares which may be included by the Holder in any such 
Registration Statement may be restricted by the Corporation if, in the opinion 
of the Corporation's managing underwriter, the number of shares proposed to be 
sold by the Holder and by the Corporation in such offering exceeds the number 
of securities which can be sold in such offering.  In such event, the 
Corporation shall include in the Registration Statement first the shares 
offered by the Corporation, and then to the extent approved for inclusion 
therein by the Corporation and its managing underwriter, that number of 
Registrable Shares so approved pro rata with any other shares of the 
Corporation's common stock, the holders of which have duly exercised 
registration rights of the type similar to this Paragraph 2(c).  All costs or 
expenses, incident to the registration, qualification or listing of such 
securities shall be paid by the Corporation, and the Corporation shall comply 
with all reasonable requests of Holder made in connection with the 
registration, qualification, listing or sale of Registrable Shares.

                  (d)  Prior to August 31, 1998, the Corporation shall not 
grant any registration rights superior to those provided to the Holder hereof 
without the prior written consent of the Holder.

         3.  Arbitration.  In the event that a dispute arises between the 
Corporation and the holder of this Warrant as to any matter relating to this 
Warrant, the matter shall be settled by arbitration in Los Angeles County, 
California in accordance with the Rules of the American Arbitration Association 
and the award rendered by such arbitrator(s) shall not be subject to appeal and 
may be entered in any federal or state court located in Los Angeles County 
having jurisdiction thereof, and actions or proceedings shall be brought in no 
other forum or venue.

                RIGHT TO PURCHASE 150,000 SHARES OF COMMON STOCK
                                       OF
                            PDG ENVIRONMENTAL, INC.


         THIS CERTIFIES THAT CVD FINANCIAL CORPORATION ("Holder") is entitled 
to purchase, on or before September 30, 2000 One Hundred Fifty Thousand 
(150,000) shares of the common stock ("Common Stock") of PDG ENVIRONMENTAL, 
INC., a Delaware corporation (the "Corporation") upon exercise of this Warrant 
along with presentation of the full price.  The purchase price of the common 
stock is equal to $0.75 per share (the "Exercise Price").  This Warrant is 
granted to Holder in consideration of Holder's execution and delivery of that 
certain Amended and Restated Loan Agreement, of even date herewith, between 
Holder, on the one hand, and the Corporation and PDG, INC., a Pennsylvania 
corporation; PROJECT DEVELOPMENT GROUP, INC., a Pennsylvania corporation; and 
ENVIRO-TECH ABATEMENT SERVICES CO., a North Carolina corporation, on the other 
hand. 

                  This Warrant may be exercised in whole or in part at any time 
and from time to time on or before September 30, 2000, by the Holder's 
presentation or surrender of this Warrant to the Corporation accompanied by 
payment of the aggregate Exercise Price for the shares as to which it is being 
exercised, or a statement that the aggregate Exercise Price is being credited 
against amounts due or to become due to Lender under the Loan Agreement, and 
instructions for delivery of the certificates representing the shares 
purchased.  In the event the Warrant is exercised in part only, the Corporation 
shall immediately issue and deliver to Holder a new Warrant, having the same 
terms and conditions as this Warrant, evidencing the right of Holder to 
purchase the number of shares as to which this Warrant has not been exercised.

                  1.  Adjustment of Exercise Price and Number of Shares 
Deliverable Upon Exercise of Warrant.  The Exercise Price and the number of 
Shares purchasable upon the exercise of this Warrant are subject to adjustment 
from time to time upon the occurrence of the events enumerated in this 
paragraph. 

                           (a)  In case the Corporation shall at any time after

                                    (i)  Pay a dividend of its shares of its 
Common Stock or make a distribution in shares of its Common Stock with respect 
to its outstanding Common Stock;

                                    (ii)  Subdivide its outstanding shares of 
Common Stock;

<PAGE>   101
                                      (iii)   Combine its outstanding shares of
Common Stock; or 

                                      (iv)    Issue any other shares of capital
stock by reclassification of its shares of Common Stock, the Exercise Price in
effect at the time of the record date of such dividend, subdivision,
combination, or reclassification shall be proportionately adjusted so that
Holder shall be entitled to receive the aggregate number and kind of shares
which, if this Warrant had been exercised prior to such event, Holder would have
owned upon such exercise and been entitled to receive by virtue of such
dividend, subdivision, combination, or reclassification.

Such adjustment shall be made successively whenever any event listed above 
shall occur.

                           (b)     In case the Corporation shall fix a record
date for the issuance of rights, options, or warrants or make a distribution of
shares of Common Stock to all (but not less than all) holders of its outstanding
Common Stock entitling them to subscribe for or purchase shares of Common Stock
(or securities convertible into shares of Common Stock) at a price per share (or
having a conversion price per share, if a security convertible into Common
Stock) less than the market price of the shares (based on the closing price on
the record date on NASDAQ or a listed securities exchange of the Corporation's
Common Stock, or if no such quote is available, the shareholders equity on the
date of the last financial statement divided by the total number of shares
outstanding) (the "Market Price"), the Exercise Price to be in effect after such
record date shall be determined by multiplying the then current Exercise Price
in effect immediately prior to such record date by a fraction, of which the
numerator shall be the number of shares of Common Stock outstanding on such
record date plus the number of shares of Common Stock which the aggregate
offering price of the total number of shares of Common Stock so to be offered
(or the aggregate initial conversion price of the convertible securities so to
be offered) would purchase at such Market Price and of which the denominator
shall be the number of shares of Common Stock outstanding on such record date
plus the number of additional shares of Common Stock to be offered for
subscription or purchase (or into which the convertible securities so to be
offered are initially convertible). Such adjustment shall be made successively
whenever such a record date is fixed; and in the event that such rights or
warrants are not so issued, the Exercise Price shall again be adjusted to be the
Exercise Price which would then be in effect if such record date had not been
fixed.

                           (c)     In case of any reorganization of the
Corporation, or in case of any reclassification or change of outstanding Common
Stock issuable upon exercise of this Warrant (other than a change in par value,
or from par value to no par value, or from no par value to par value, or as a
result of a subdivision or split-up or combination of the Common Stock), or in
case of any consolidation or merger of the 


                                      -2-

<PAGE>   102
Company with or into another entity (other than a consolidation or merger with 
a subsidiary or a continuing corporation), or in case of any sale or conveyance 
to another entity of all or substantially all of the property of the 
Corporation, then, as a condition of such reorganization, reclassification, 
change, consolidation, merger, sale, or conveyance, the Corporation or such 
successor or purchasing entity, as the case may be, shall forthwith provide to 
Holder a supplemental warrant (the "Supplemental Warrant") which will make 
lawful and adequate provision whereby Holder shall have the right thereafter to 
receive, upon exercise of such Supplemental Warrant, the kind and amount of 
shares and other securities and property which would have been received upon 
such reorganization, reclassification, change, consolidation, merger, sale, or 
conveyance by a holder of a number of shares of Common Stock equal to the 
number of Shares issuable upon exercise of this Warrant immediately prior to 
such reorganization, reclassification, change, consolidation, merger, sale, or 
conveyance. Such Supplemental Warrant shall include provision for adjustments 
which shall be as nearly equivalent as may be practicable to the adjustments 
provided for in this paragraph. The above provisions of this paragraph shall 
similarly apply to successive reorganizations, reclassifications, and changes 
of Common Stock and to successive consolidations, mergers, sales, or 
conveyances. 

                  2.      Registration Rights.

                          (a)     Subject to the provisions of Paragraph 2(b),
below, at any time prior to September 30, 2000 Holder may make a written demand
on the Corporation for registration (a "Demand Registration") under the
Securities Act of 1933, as amended (the "Act") of all or a part of the shares
purchased or purchasable upon the exercise of this Warrant (the "Registrable
Shares"). Holder shall be entitled to one Demand Registration only. Upon receipt
of a Demand Registration, the Corporation shall take such steps as may be
reasonably necessary to register such securities under the Act as promptly as
possible, including the preparation and filing of a registration statement
("Registration Statement") with the Securities Exchange Commission and all
necessary amendments thereto, such registration to take effect not later than
sixty (60) days following the date of Holder's demand. In addition, the
Corporation shall take such actions as may be necessary to register or qualify
the Registerable Shares for sale in such states and jurisdictions as Holder may
direct on or prior to the effective date of such Registration Statement under
any local securities or "blue sky" laws. All costs or expenses incident to the
registration, qualification or listing of such securities shall be paid by the
Corporation, and the Corporation shall comply with all reasonable requests of
Holder made in connection with the registration, qualification, listing or sale
of Registrable Shares. Without the prior written consent of Holder, the
Corporation shall not effect any public sale or distribution of its debt or
equity securities during the ten (10)-day period prior to, or during the ninety
(90)-day period beginning on, the effective date of any Registration Statement
covering any Registrable Shares which are the subject of the Demand
Registration. 


                                      -3-

<PAGE>   103
                           (b)     Notwithstanding the foregoing, the
Corporation shall be entitled to defer the filing of a Registration Statement
required by Demand Registration for a period not to exceed sixty (60) days after
receipt of such demand if: (i) the Corporation is contemplating an underwritten
public offering of its securities and, in the judgment of the managing
underwriter thereof, such filing of the Registration Statement for the Demand
Registration would have a material adverse effect on the Corporation's
contemplated offering; (ii) the Corporation is in possession of material
information that it deems advisable not to disclose in a Registration Statement,
provided that such information is revealed to Holder and Holder agrees with the
Corporation's decision not to disclose such information; or (iii) the
Corporation is prohibited (pursuant to the terms of an underwriting agreement
previously approved by the Holder in connection with a public offering of its
securities effected within the past six (6) months) from filing such
Registration Statement. 

                           (c)     Holder shall also have the right, at any time
and from time to time until September 30, 2000 to include Registrable Shares
within any Registration Statement of the Corporation filed by the Corporation
covering shares of its Common Stock other than a Registration Statement filed
solely with respect to any employee benefit plan of the Corporation (and
provided that the form of Registration Statement is a type on which the
Registrable Shares can be registered). The Corporation shall promptly give
written notice to Holder of any intended registration of its Common Stock not
less than forty-five (45) days prior to the anticipated effective date of the
Registration Statement, and Holder shall, within fifteen (15) days of receipt
thereof, notify the Corporation of the number of Registrable Shares it desires
to include in the Registration Statement. Subject to the approval of the
Corporation's managing underwriter, the Holder shall be entitled to include up
to all of its Registrable Shares, at its election, within the first Registration
Statement filed by the Corporation following the date hereof. The number of
Registrable Shares which may be included by the Holder in any such Registration
Statement may be restricted by the Corporation if, in the opinion of the
Corporation's managing underwriter, the number of shares proposed to be sold by
the Holder and by the Corporation in such offering exceeds the number of
securities which can be sold in such offering. In such event, the Corporation
shall include in the Registration Statement first the shares offered by the
Corporation, and then to the extent approved for inclusion therein by the
Corporation and its managing underwriter, that number of Registrable Shares so
approved pro rata with any other shares of the Corporation's common stock, the
holders of which have duly exercised registration rights of the type similar to
this Paragraph 2(c). All costs or expenses, incident to the registration,
qualification or listing of such securities shall be paid by the Corporation,
and the Corporation shall comply with all reasonable requests of Holder made in
connection with the registration, qualification, listing or sale of Registrable
Shares.

<PAGE>   104
                           (d)     Prior to September 30, 2000 the Corporation
shall not grant any registration rights superior to those provided to the Holder
hereof without the prior written consent of the Holder.

                  3.       Arbitration. In the event that a dispute arises
between the Corporation and the holder of this Warrant as to any matter relating
to this Warrant, the matter shall be settled by arbitration in Los Angeles
County, California in accordance with the Rules of the American Arbitration
Association and the award rendered by such arbitrator(s) shall not be subject to
appeal and may be entered in any federal or state court located in Los Angeles
County having jurisdiction thereof, and actions or proceedings shall be brought
in no other forum or venue.

         IN WITNESS WHEREOF, the Corporation has caused this Warrant to be
executed by its duly authorized officers effective as of the 31st day of
October, 1995.

                               GUARANTY AGREEMENT


        THIS GUARANTY AGREEMENT ("Agreement") is made as of the 31st day of 
October, 1995 by JOHN REGAN and ELEANOR REGAN (the "Guarantors"), having a 
notice address at 482 Hillside Avenue, Monroeville, Pennsylvania 14156, in 
favor of CVD FINANCIAL CORPORATION, its successors and assigns (the "Lender"), 
having a notice address at Suite 1290 Burrard Street, Vancouver, British 
Columbia V6C 3A6, Canada.

                                  WITNESSETH:

        WHEREAS, concurrent with the execution of this Agreement, the Lender 
has entered into an Amended and Restated Loan Agreement, dated as of October 
31, 1995, with PDG ENVIRONMENTAL, INC., a Delaware corporation; PDG, INC., a 
Pennsylvania Corporation; PROJECT DEVELOPMENT GROUP, INC., a Pennsylvania 
corporation; and ENVIRO-TECH ABATEMENT SERVICES CO., a North Carolina 
corporation (collectively the "Borrower"); and Guarantors (the "Loan 
Agreement"), which Loan Agreement amends and restates the existing Loan 
Agreements and Loan Documents described in the Loan Agreement governing the 
Integra Loans and the PDGE Loans (as defined in the Loan Agreement); and

        WHEREAS, the foregoing loans, as amended and restated, are now 
represented by a Revolving Loan and Term Loan (the "Loans") as provided under 
the Loan Agreement and are secured by certain security interests described in 
the Loan Agreement and the Loan Documents (as defined therein); and

        WHEREAS, each of the Guarantors has previously delivered to the Lender 
in connection with the PDGE Loans a separate Guaranty Agreement, dated
March 23, 1994, and has delivered to Lender's predecessor(s)-in-interest under
the Integra Loans, a Suretyship Agreement dated November 5, 1991, as amended, 
respecting the Integra Loans (respectively, the "Guaranty Agreements" and 
"Suretyship Agreements"); and

        WHEREAS, this Agreement is executed by the Guarantors and delivered to 
Lender to induce Lender to enter into the Loan Agreement and in satisfaction of 
a material condition precedent to the execution and delivery of such Loan 
Agreement by the Lender, and is intended to amend and restate, in their 
entirety, the prior Guaranty Agreements and Suretyship Agreements.

        NOW, THEREFORE, in consideration of the Loan by the Lender to the 
Borrower, the benefits to be derived by the Guarantors therefrom and other good 
and valuable consideration, the receipt and sufficiency of which are hereby 
acknowledged by the Guarantors, it is agreed as follows:


                                  SCHEDULE "M"
<PAGE>   112
         1.  The Guarantors jointly and severally guarantee to the Lender the 
absolute, complete and punctual performance of the agreements of the Borrower 
contained in the Loan Documents, including, without implied limitation, the 
payment of all principal, interest, attorneys' fees, expenses of collection and 
other sums now or hereafter owing by the Borrower to the Lender thereunder and 
all other sums which may become owing by the Borrower to the Lender for any 
reasons or by any cause whatsoever at any time in the future. The obligation of 
the Guarantors hereunder is an absolute, unlimited, unconditional and 
continuing guaranty of payment and performance by the Borrower, which shall 
remain effective during the term of the Loan Agreement or any of the Loan 
Documents, and shall relate to any liability or obligation of the Borrower 
whatsoever to the Lender, including those which arise under successive 
transactions, until this Agreement has been expressly terminated. Such 
termination shall be applicable only to transactions having their inception 
after the effective date of termination and shall not affect any rights or 
obligations arising out of the Loan Documents or any other transactions having 
their inception prior to such date even if subsequent to such termination such 
obligations are modified, renewed, compromised, extended or otherwise amended 
in any way whatsoever. This Agreement shall not apply to any obligation created 
after actual receipt by the Lender of written notice of termination of this 
Agreement as to future transactions.

         2.  The Guarantors agree that the Guarantors' liability hereunder will 
not be released, reduced, impaired or affected by the occurrence of any one or 
more of the following events: (a) the Lender's obtaining collateral from the 
Borrower or any other person to secure payment or performance under the Loan 
Documents; (b) the assumption of liability by any other person (whether as 
guarantor or otherwise) for payment or performance under the Loan Documents; 
(c) the release, surrender, exchange, loss, termination, waiver or other 
discharge of any of the collateral securing payment or performance under the 
Loan Documents; (d) the subordination, relinquishment or discharge of the 
Lender's rights relating to the Loan Documents or any of the collateral 
described therein; (e) the full or partial release from liability of the 
Borrower or any other guarantor of any obligation of the Borrower to the Lender 
or any other person now or hereafter liable for payment or performance under 
the Loan Documents; (f) the death, insolvency, bankruptcy, reorganization, 
disability, discharge, waiver or other exoneration of the Borrower or any other 
guarantor of any obligation of the Borrower to the Lender or any other person 
now or hereafter liable for payment or performance under the Loan Documents; 
(g) the extension, renewal, rearrangement, increase, consolidation, 
modification or substitution from time to time of the Loans or of the terms of 
any one or more of the Loan Documents; (h) the failure, delay, waiver or 
refusal by the Lender to exercise any right or remedy held by the Lender under 
the Loan Documents; (i) the sale, encumbrance, transfer or other modification 
of the ownership of the Borrower or the Borrower's assets or a change in the 
financial condition or management of the Borrower; (j) the invalidity, 
unenforceability or insufficiency of any one or more of the Loan Documents or 
any of the collateral securing payment or performance thereunder; or (k) the 
failure of the Guarantors to receive notice of any one or more of the foregoing 
actions or events.



                                      -2-


<PAGE>   113
        3.  The Lender may, at the option of the Lender, proceed to enforce 
this Agreement directly against the Guarantors, or any of them, without first 
proceeding against the Borrower, any other guarantor, or any other person 
liable for payment or performance under the Loan Documents and without first 
proceeding against or exhausting any collateral now or hereafter held by 
the Lender to secure payment or performance under the Loan Documents, and the 
Guarantors waive any and all rights that they may have to require the Lender to 
take any such action as a condition to enforcement of this Agreement.

        4.  The Guarantors waive diligence, presentment, protest, notice of 
dishonor, demand for payment, notice of nonpayment or nonperformance, notice of 
acceptance of this Agreement and all other notices of any nature in connection 
with the exercise of the Lender's rights under the Loan Documents or this 
Agreement. Performance by the Guarantors hereunder will not entitle the 
Guarantors to any payment by the Borrower or any other guarantors of the 
obligations of the Borrower under the Loan Documents by reason of any claim for 
contribution, indemnification, subrogation or otherwise. The Guarantors waive 
all rights to setoffs and counterclaims against the Lender and agrees that any 
rights which the Guarantors might now or hereafter hold against the Borrower 
and any other Guarantor of the obligations of the Borrower under the Loan 
Documents will be subordinate, junior and inferior to all rights which the 
Lender might now or hereafter hold against the Borrower and any other guarantor 
of the obligations of the Borrower under the Loan Documents. Without in any way 
limiting the foregoing, Guarantors hereby waive any defenses arising by reason 
of any claim based upon an election of remedies by the Lender which, in any 
manner impairs, affects, reduces, releases, destroys and/or extinguishes the 
Guarantors' subrogation rights, rights to proceed against the Borrower for 
reimbursement and/or any other rights of the Guarantors to proceed against the 
Borrower, against any other guarantor or against any other person or security, 
including without implied limitation, any defense based upon: (a) an election 
of remedies by the Lender under the provisions of Sections 580d and/or 726 of 
the California Code of Civil Procedure, and/or any similar law of California or 
of any other jurisdiction whereby the Lender's election to foreclose under a 
power of sale or otherwise without judicial proceedings with respect to real 
property may eliminate the subrogation rights that the Guarantors would 
otherwise have to seek to recover from the Borrower any sums paid to the Lender 
on account of the obligations guaranteed; or (b) a claim that the Lender has 
failed to proceed in a commercially reasonable manner in connection with the 
Lender's foreclosure upon any security.

        5.  The Guarantors agree that in any action brought to enforce this 
Agreement, the Guarantors will pay to the Lender the reasonable attorneys' 
fees, court costs and other litigation expenses incurred by the Lender unless 
the court before which such enforcement action is brought makes a final 
determination that Guarantors is the prevailing party in such action.

        6.  Nothing herein contained will limit the Lender in exercising any 
rights held under any one or more of the Loan Documents. On the occurrence of 
any event of default under the Loan Documents or this Agreement, the Lender 
will be entitled to selectively and successively enforce any one or more of the 
rights held by the Lender and such action will not be deemed a waiver of any 
other right held by the Lender. All of the remedies of the Lender



                                      -3-
<PAGE>   114
under this Agreement and the Loan Documents are cumulative and not alternative. 
If the Lender elects to foreclose any lien created by the Loan Documents, the 
Lender is authorized to purchase for the account of the Lender all or any part 
of the collateral covered by such lien at public or private sale and to credit 
the amount recovered first against any portion of the Loan for which the 
Guarantors are determined not to be liable with any balance remaining to be 
applied in reduction of the liability of the Guarantors hereunder.

        7.      The obligations of the Guarantors under this Agreement will 
continue to be effective or be reinstated, as the case might be, if at any time 
any payment from the Borrower of any sum due to the Lender is rescinded or must 
otherwise be restored or returned by the Lender on the insolvency, bankruptcy, 
dissolution, liquidation or reorganization of the Borrower or as a result of 
the appointment of a custodian, receiver, trustee or other officer with similar 
powers with respect to the Borrower or any part of Borrower's property or 
otherwise. If an event permitting the acceleration of the maturity of the Loan 
has occurred and is continuing and such acceleration is at such time prevented 
by reason of the pendency against the Borrower of a proceeding under any 
bankruptcy or insolvency law, the Guarantors agree that, for the purposes of 
this Agreement and the obligations of the Guarantors under this Agreement, the 
maturity of the Loan will be deemed to have been accelerated with the same 
effect as if the Lender had accelerated the same in accordance with the terms 
of the Loan Documents and the Guarantors will immediately pay the unpaid 
balance of the Loan.

        8.      No payment by the Guarantors to the Lender pursuant to the 
provisions of this Agreement will entitle the Guarantors (by subrogation to the 
rights of the Lender in respect of which such payment is made or otherwise) to 
any payment by the Borrower or out of the property of the Borrower, except 
after indefeasible payment in full of all amounts and obligations owing to the 
Lender by the Borrower and all other guarantors of the obligations of the 
Borrower under the Loan Documents.

        9.      The Guarantors agree to furnish to the Lender within forty-five 
(45) days after the end of each calendar year, in such detail as the Lender 
might reasonably request, a statement of assets and liabilities (both direct 
and contingent) and of the source and amount of the annual income of Guarantors 
as of December 31 of the preceding calendar year certified to be accurate by
the Guarantors.

        10.     This Agreement has been negotiated, executed and delivered in 
the State of California, and is intended to be construed in accordance with the 
laws of the State of California.

        11.     THE GUARANTORS HEREBY EXPRESSLY WAIVE ANY RIGHT TO TRIAL BY 
JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (1) ARISING UNDER THIS 
AGREEMENT, ANY OF THE LOAN DOCUMENTS OR ANY OTHER INSTRUMENT, DOCUMENT OR 
AGREEMENT EXECUTED OR DELIVERED IN CONNECTION HEREWITH, OR (2) IN ANY WAY 
CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES THERETO 
OR ANY OF THEM
 

                                        -4-
<PAGE>   115
WITH RESPECT TO THIS AGREEMENT, THE LOAN DOCUMENTS, OR ANY OTHER INSTRUMENT, 
DOCUMENT OR AGREEMENT EXECUTED OR DELIVERED IN CONNECTION HEREWITH, OR THE 
TRANSACTIONS RELATED HERETO OR THERETO, IN EACH CASE WHETHER NOW EXISTING OR 
HEREAFTER ARISING, AND WHETHER SOUNDING IN CONTRACT OR TORT OR OTHERWISE; AND 
THE GUARANTORS HEREBY AGREE AND CONSENT THAT ANY SUCH CLAIM, DEMAND, ACTION OR 
CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY, AND THAT ANY 
PERSON MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION WITH ANY 
COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE GUARANTORS TO THE WAIVER OF 
THEIR RIGHT TO TRIAL BY JURY.

                12.     Guarantors are presently informed of the financial 
condition of the Borrower and of all other circumstances which a diligent 
inquiry would reveal and which would bear upon the risk of non-payment of any 
obligation owing or which may become owing by the Borrower to the Lender. 
Guarantors hereby covenant that Guarantors will continue to keep themselves 
informed of the Borrower's financial condition, the status of other guarantors, 
if any, and of all other circumstances which bear upon the risk of non-payment. 
Guarantors hereby waive their rights, if any, to require the Lender to disclose 
to him any information which the Lender may now or hereafter acquire concerning 
such conditions or circumstances, including, but not limited to the release of 
or the revocation of any guaranty by any other guarantor.

                13.     If any provision of this Agreement is held to be 
invalid, illegal or unenforceable in any respect or application for any reason, 
such invalidity, illegality or unenforceability will not affect any other 
provisions herein contained and such other provisions will remain in full force 
and effect. This Agreement will be binding on the Guarantors and all heirs, 
personal representatives, successors and assigns of the Guarantors and will 
inure to the benefit of the Lender and all successors and assigns of the 
Lender. The Guarantors consent to the assignment of all or any portion of the 
rights of the Lender hereunder in connection with any assignment of all or any 
portion of the rights of the Lender under the Loan Documents without notice to 
the Guarantors. This Agreement cannot be amended except by an agreement in 
writing signed by the Guarantors and the Lender.

                14.     This Agreement and the liability of Guarantors 
hereunder shall be unlimited in amount.

                IN WITNESS WHEREOF, the Guarantors have duly executed this 
Agreement effective the date first above written.

                           (i) To do all acts that may be necessary to

                           (ii) Not to use or permit any Collateral to be used

affecting any Collateral;

                           (iv) To procure, execute and deliver from time to

for such purpose;

                           (vii) To keep separate, accurate and complete

repair; 



                                      -4-

                        
<PAGE>   121
                           (xi)    Not to cause or permit any waste or unusual
or unreasonable depreciation of the Collateral;

                           (xii)   At any reasonable time, on demand by the 
Lender, to exhibit to and allow inspection of the Collateral or to assemble the

days' prior written notice of any change in any Borrower's places of business 
or trade name(s) or style(s) set forth in Exhibit "A";

                           (xiv)   To comply with all laws, regulations and 
ordinances relating to the possession, operation, maintenance and control of 
the Collateral;

                           (xv)    To insure the Collateral, with the Lender 
named as loss payee, in form and amounts, with companies, and against risks and 
liabilities satisfactory to the Lender, and hereby assigns the policies to the 
Lender, agrees to deliver them to the Lender at the Lender's request, and
agrees that the Lender may make any claim thereunder, cancel the insurance on
default by the Borrowers, collect and receive payment of and endorse any
instrument in payment of loss or return premium or other refund or return, and
apply such amounts received, at the Lender's election, to replacement of
Collateral or to payment of the Revolving Loan and Term Loan;

                            (xvi)  Borrowers acknowledge and agree that all of 
the Collateral is and will remain personal property, notwithstanding the manner 
of its annexation to any real property and its adaptability to the uses and 
purposes for which any such real property is now or may hereafter be used, and 
no present or future real property lease entered into by any Borrower as lessee 
will grant the lessor therein any rights to the Collateral or prohibit its 
removal, whether or not any Borrower is in default under the lease, and 
Borrowers, upon Lender's request, will deliver to Lender such waivers and 
consents from any such lessor and from any encumbrancer of any real property on 
which any Collateral may be located as Lender may request; and

                             (xvii) Lock Box.  At Lender's request, upon 
occurrence of any Event of Default as defined under the Loan Agreement or under 
any of the Loan Documents, which is not cured to the satisfaction of Lender 
within any applicable cure period, the Borrowers shall maintain in effect at 
all times with such bank or other financial institution as may be designated by 
Lender, a lock box account or accounts wherein all checks, drafts, cash and 
other remittances to the Borrowers, in payment of their Accounts and other 
Collateral, shall be deposited immediately for or in trust for


                                        -5-
<PAGE>   122

the Lender until repayment in full of all sums due from the Borrowers to 
Lender.  Without in any way limiting the foregoing, the Borrowers agree that:

                                    (A)  The Borrowers and Lender shall be the 
only parties entitled to receive any payments from any Account debtor 
respecting all accounts.

                                    (B)  Upon demand by Lender, the Borrowers 
hereby agree that all proceeds of the Accounts and other Collateral which may 
be received by any Borrower shall be delivered, transferred, assigned and 
endorsed in the exact form they are received, or as otherwise directed by the 
Lender, and shall not be deposited or commingled with any other assets of any 
Borrower.  In the event a Borrower receives any payments it was unauthorized to 
receive, they shall be held in trust for Lender and shall be delivered to 
Lender or its designated bank or financial institution in the exact form 
received except for any endorsement of the Borrower where necessary to permit 
collection, which the Borrowers hereby agree to make.

                                    (C)  The Borrowers further agree to 
immediately notify the account debtors under the Accounts and other Collateral 
to make payments of all sums due, at Lender's option, directly to the Lender or 
to the lock box account at such address as may be directed by Lender, and to  
indicate on all invoices to such account debtors that all payments are to be
made directly to the Lender or to the lock box.  The Borrowers shall provide
Lender with copies of any such notices concurrent with the delivery thereof to
the account debtors, and of all invoices sent after the date Lender gives notice
of its intention to implement these lock box provisions.  Any lock box
maintained may, at Lender's option, be maintained in the name of any one or more
Borrowers but Lender shall have the sole access to such lock box.

                                    (D)  The Borrowers hereby jointly, 
severally and irrevocably appoint the Lender the attorney-in-fact of each and 
all of them to do (but the Lender shall not be obligated to and will not incur 
any liability to any third party for any failure so to do) any act which any 
Borrower is obligated by any Loan Document of any kind to do, including without 
implied limitation, the collection, endorsement and receipt of all payments or 
proceeds payable on or on account of the Accounts or the delivery of any 
notices, including any notices to account debtors.

                                    (E)  The foregoing lock box and collection 
provisions may be implemented by Lender in its sole and absolute discretion 
upon its determination that an Event of Default has occurred and has not been 
cured, and Lender shall not have any liability of any kind to any Borrower or 
any other person in the event Lender has incorrectly determined that an Event 
of Default exists, it being understood that the parties acknowledge that Lender 
has, as of the date hereof, the sole, absolute and unrestricted right to 
currently impose such lock box requirements 


                                      -6-
<PAGE>   123

upon the Borrowers or to directly collect all Accounts by reason of the current 
Events of Default respecting the Loans listed on Schedule "A" to the Loan 
Agreement.

                  (b)  Actions By Lender.  The Borrowers hereby irrevocably 
appoint the Lender as the Borrowers' attorney-in-fact to do (but the Lender 
will not be obligated to and will incur no liability to the Borrowers or any 
third party for failure so to do) any act which the Borrowers are obligated by 
this Agreement to do, and to exercise such rights and powers as the Borrowers 
might exercise with respect to the Collateral, including, without implied 
limitation, the right to:

                           (i)  Collect by legal proceedings or otherwise and 
endorse, receive and receipt for all dividends, interest, payments, proceeds 
and other sums and property now or hereafter payable on or on account of the 
Collateral;

                           (ii)  Enter into any extension, reorganization, 
deposit, merger, consolidation or other agreement pertaining to, or deposit, 
surrender, accept, hold or apply other property in exchange for the Collateral;

                           (iii)  Insure, process and preserve the Collateral;

                           (iv)  Transfer the Collateral to the Lender's own or 
the Lender's nominee's name; and

                           (v)  Make any compromise or settlement and take any 
action the Lender deems advisable with respect to the Collateral.  The 
appointment of the Lender as the Borrowers' attorney-in-fact will not impose on 
the Lender any duty to take any action on behalf of the Borrowers or establish 
any fiduciary obligation owing by the Lender to the Borrowers.  The Borrowers 
agree to reimburse the Lender on demand for any costs and expenses, including, 
without implied limitation, attorneys' fees the Lender might incur while acting 
as the Borrowers' attorney-in-fact hereunder, all of which costs and expenses 
are included in the indebtedness hereby secured.  It is agreed that such care 
as the Lender gives to the safekeeping of the Lender's own property of like 
kind will constitute reasonable care of the Collateral when in the Lender's 
possession; provided, however, the Lender will not be required to make any 
presentment, demand or protest, or give any notice and need not take any action 
or preserve any rights against any prior party or any other person in 
connection with the indebtedness hereby secured or with respect to the 
Collateral.

         4.  Filing Information.  The Borrowers represent and warrant to the 
Lender that the principal place of business of each Borrower, all other 
business locations, trade names and trade styles of such Borrowers, the 
location of the Collateral, and the Borrower's location of books and records 
concerning the Collateral are as set forth in Exhibit "A."


                                      -7-

<PAGE>   124

         5.  Remedies.  On the occurrence of any Event of Default which is not 
cured to the satisfaction of Lender within any applicable cure period, the 
Lender may, without demand for performance or any other demand, advertisement 
or notice of any kind (except the notice specified below of the time and place 
of public or private sale) to the Borrowers or to any other person (all of 
which are hereby expressly waived), forthwith foreclose the security interest 
covering the Collateral or any part thereof and sell or otherwise dispose of 
and deliver the Collateral or any part thereof or interest therein, in one or 
more parts at public or private sale or sales, or at the Lender's offices or 
elsewhere, at such prices and on such terms as the Lender deems best, with the 
Lender or any purchaser to have the right to purchase the whole or any part of 
the Collateral free of any right or equity of redemption in the Borrowers, 
which right or equity is hereby expressly, waived and relinquished.  The 
proceeds of any such disposition or other action by the Lender will be applied 
as follows:

                  (a)  First, to the costs and expenses reasonably incurred in 
connection with the retaking and sale of any of the Collateral or to the care 
or safekeeping of any of the Collateral or in any way relating to the exercise 
of the rights of the Lender under this Agreement, including reasonable 
attorneys' fees and expenses;

                  (b)  Second, to the payment of the Revolving Loan and the 
Term Loan or prior secured indebtedness of Borrowers in such order as Lender 
may elect;

                  (c)  Third, to the payment of any other amounts required by 
applicable law including, without implied limitation, Section 9-504(1)(c) of 
the California Commercial Code; and

                  (d)  Fourth, to the Borrowers to the extent of any surplus 
proceeds.  The Lender will give at least ten (10) days' notice of the time and 
place of any public sale or the time after which a private sale may take place, 
which notice the Borrowers agree is reasonable.  The Lender's rights and 
remedies described in this Agreement are in addition to those possessed by the 
Lender pursuant to the California Commercial Code and other applicable laws of 
the State of California.  All rights and remedies of the Lender will be 
cumulative and may be exercised successively or concurrently without impairing 
the Lender's interest in the Collateral.

        6.      Miscellaneous.  It is further agreed as follows:

                (a)     Time.  Time is the essence of each provision of this 
Agreement. 

                (b)     Notices.  Any notice, demand or communication required 
or permitted to be given by any provision of this Agreement will be in writing 
and will be deemed to have been given when delivered personally or by 
telefacsimile, receipt confirmed, to the party designated to receive such 
notice, or on the date following the day sent by overnight courier or on the 
third (3rd) business day after the same is sent by certified mail, postage and 
charges prepaid, directed to the addresses stated in this Agreement or to such 
other or additional addresses as either party might designate by written notice 
to the other party. Notice to any Borrower at the address set forth on the 
first page of this Agreement shall be deemed, for all purposes, to constitute 
notice to all Borrowers.

                (c)     Cumulative Remedies.  No failure on the part of the 
Lender to exercise, and no delay in exercising any right under this Agreement 
will operate as a waiver thereof, nor will any single or partial exercise by 
the Lender of any right under this Agreement preclude any other or further 
right of exercise thereof or the exercise of any other right.

                (d)     Amendment.  Neither this Agreement nor any of the 
provisions hereof can be changed, waived, discharged or terminated, except by 
an instrument in writing signed by the party against whom enforcement of the 
change, waiver, discharge or termination is sought.

                (e)     Severability.  The provisions of this Agreement are 
severable, and if any clause or provision is held invalid, illegal or 
unenforceable in any respect in any jurisdiction, the validity, legality and 
enforceability of the remaining provisions contained herein will not be in any 
way affected or impaired thereby.

                (f)     Assignment.  This Agreement cannot be assigned by the 
Borrowers in whole or in part without the prior written consent of the Lender.

                (g)     Binding Effect.  This Agreement will be binding on and 
will inure to the benefit of the Borrowers, the Lender and their respective 
successors and permitted assigns.

                (h)     JURY WAIVER.  THE BORROWERS HEREBY EXPRESSLY WAIVE ANY 
RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (1) 
ARISING UNDER THIS AGREEMENT, ANY OF THE LOAN DOCUMENTS DESCRIBED HEREIN OR ANY 
OTHER INSTRUMENT, DOCUMENT OR AGREEMENT EXECUTED OR DELIVERED IN CONNECTION 
HEREWITH, OR (2) IN ANY WAY CONNECTED WITH OR



                                      -9-
<PAGE>   126
RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES THERETO OR ANY OF THEM 
WITH RESPECT TO THIS AGREEMENT, THE LOAN DOCUMENTS, OR ANY OTHER INSTRUMENT, 
DOCUMENT OR AGREEMENT EXECUTED OR DELIVERED IN CONNECTION HEREWITH, OR THE 
TRANSACTIONS RELATED HERETO OR THERETO, IN EACH CASE WHETHER NOW EXISTING OR 
HEREAFTER ARISING, AND WHETHER SOUNDING IN CONTRACT OR TORT OR OTHERWISE; AND 
THE BORROWERS HEREBY AGREE AND CONSENT THAT ANY SUCH CLAIM, DEMAND, ACTION OR 
CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY, AND THAT ANY 
PERSON MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION WITH ANY 
COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE BORROWERS TO THE WAIVER OF 
THEIR RIGHT TO TRIAL BY JURY.

         IN WITNESS WHEREOF, the undersigned have executed and delivered this 
Security Agreement effective the date first above written.
