                       W. R. GRACE & CO. AND SUBSIDIARIES
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

- --------------------------------------------------------------------------------
1.  CHANGE IN ORGANIZATION AND BASIS OF PRESENTATION
- --------------------------------------------------------------------------------

W. R. Grace & Co., through its subsidiaries, is primarily engaged in specialty
chemicals businesses on a worldwide basis. These businesses consist of catalysts
and silica-based products (Grace Davison), specialty construction chemicals and
building materials (Grace Construction Products), and container sealants,
closure sealants, and coatings (Darex Container Products). As used in these
notes, the term "Company" refers to W. R. Grace & Co., a Delaware corporation.
The term "Grace" refers to the Company and/or one or more of its subsidiaries
and, in certain cases, their respective predecessors. Grace has classified
certain businesses as discontinued operations.

PACKAGING BUSINESS TRANSACTION

On March 31, 1998, a predecessor of the Company (Old Grace) completed a
transaction in which Grace's former flexible packaging business (Packaging
Business) was combined with Sealed Air Corporation (Sealed Air). Old Grace
effected this transaction by transferring its specialty chemicals businesses
along with certain other businesses and assets to the Company, distributing the
shares of the Company's common stock to Old Grace's shareholders on a
one-for-one basis (Spin-off) and merging a subsidiary of Old Grace with Sealed
Air (Merger). Immediately following the Spin-off and Merger, the Company changed
its name to "W. R. Grace & Co." and Old Grace changed its name to "Sealed Air
Corporation" (New Sealed Air).

For further information, see Old Grace's Joint Proxy Statement/Prospectus dated
February 13, 1998, the Company's Information Statement dated February 13, 1998,
Notes 1 and 3 to the Consolidated Financial Statements in Grace's Annual Report
on Form 10-K for 1998 (1998 Form 10-K), and Note 3 below.

BASIS OF PRESENTATION

The interim consolidated financial statements in this Report are unaudited and
should be read in conjunction with the consolidated financial statements in the
Company's 1998 Form 10-K. Such interim consolidated financial statements reflect
all adjustments that, in the opinion of management, are necessary for a fair
presentation of the results of the interim periods presented; all such
adjustments are of a normal recurring nature. All significant intercompany
accounts and transactions have been eliminated. Certain amounts in the
consolidated financial statements for prior periods have been reclassified to
conform to the current period's basis of presentation.

The results of operations for the three and six month interim periods ended June
30, 1999, are not necessarily indicative of the results of operations for the
year ending December 31, 1999.

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles requires that management make estimates and assumptions
affecting the assets and liabilities (including contingent assets and
liabilities) reported at the date of the consolidated financial statements and
the revenues and expenses reported for the periods presented. Actual amounts
could differ from those estimates.

2.  ASBESTOS RELATED LITIGATION
- --------------------------------------------------------------------------------

Grace is a defendant in property damage and personal injury lawsuits relating to
previously sold asbestos-containing products and expects that it will be named
as a defendant in additional asbestos-related lawsuits in the future. Grace was
a defendant in 46,204 asbestos-related lawsuits on June 30, 1999 (12 involving
claims for property damage and the remainder involving 100,314 claims for
personal injury), as compared to 45,086 lawsuits on December 31, 1998 (14
involving claims for property damage and the remainder involving 97,017 claims
for personal injury).

PROPERTY DAMAGE LITIGATION

The plaintiffs in property damage lawsuits generally seek to have the defendants
absorb the cost of removing, containing or repairing the asbestos-containing
materials in the affected buildings. Each property damage case is unique in that
the age, type, size and use of the building, and the difficulty of asbestos
abatement, if necessary, vary from structure to structure. Thus, the amounts
involved in prior dispositions of property damage cases are not necessarily
indicative of the amounts that may be required to dispose of cases in the
future. Information regarding product identification, the amount of product in
the building, the age, type, size and use of the building, the jurisdictional
history of prior cases and the court in which the case is pending provide
meaningful guidance as to the range of potential costs. Some of this information
is not yet available in the property damage cases currently pending against
Grace. Accordingly, it is not possible to estimate with precision the costs of
defending against and disposing of these cases. In accordance with Statement of
Financial Accounting Standards (SFAS) No. 5, "Accounting for Contingencies,"
Grace has recorded an accrual for all existing property damage cases for which
sufficient information is available to form a reasonable estimate of such
exposure.

Through June 30, 1999, 140 asbestos property damage cases were dismissed without
payment of any damages or settlement amounts; judgments were entered in favor of
Grace in nine cases (excluding cases settled following appeals of judgments in
favor of Grace); judgments were entered in favor of the plaintiffs in seven
cases for a total of $60.3 million; and 202 property damage cases were settled
for a total of $602.6 million. Property damage case activity for the six months
ended June 30, 1999, was as follows:

- --------------------------------------------------------------------------------

PERSONAL INJURY LITIGATION

Personal injury claims are generally similar to each other (differing primarily
in the type of asbestos-related illness allegedly suffered by the plaintiff).
However, Grace's estimated liability for such claims is influenced by numerous
variables, including the solvency of other former asbestos producers,
cross-claims by co-defendants, the rate at which new claims are filed, the
jurisdiction in which the filings are made, and the defense and disposition
costs associated with these claims.



                                      I-6
<PAGE>

Through June 30, 1999, approximately 13,800 asbestos personal injury lawsuits
involving 31,500 claims were dismissed without payment of any damages or
settlement amounts (primarily on the basis that Grace products were not
involved), and approximately 47,000 lawsuits involving 119,400 claims were
disposed of (through settlements and judgments) for a total of $382.3 million.
Personal injury claim activity for the six months ended June 30, 1999 was as
follows:

- --------------------------------------------------------------------------------

Claims outstanding, December 31, 1998..........................    97,017
New claims.....................................................    14,752

- --------------------------------------------------------------------------------

ASBESTOS-RELATED LIABILITY

Grace estimates its property damage and personal injury liabilities based on its
experience with, and recent trends in, asbestos litigation. These estimates
include property damage and personal injury indemnity as well as defense costs.
Personal injury liabilities reflect Grace's estimate of the number and ultimate
cost of present and future personal injury claims expected to be asserted
through 2039 (the date by which all personal injury claims related to Grace are
expected to be known, given demographic assumptions of possible exposure to
asbestos products manufactured by Grace). Grace regularly evaluates its
financial exposure to asbestos-related lawsuits and the adequacy of related
recorded liabilities. The amounts recorded at each balance sheet date reflect
Grace's best estimate of probable and estimable liabilities in all material
respects. However, changes to estimates of probable liabilities may occur as
actual experience is gained over time.

Grace has settled with and been paid by its primary insurance carriers with
respect to both property damage and personal injury cases and claims. Grace has
also settled with its excess insurance carriers that wrote policies available
for property damage cases; those settlements involve amounts paid and to be paid
to Grace. In addition, Grace has settled with many excess insurance carriers
that wrote policies available for personal injury claims. Grace is currently in
litigation with certain remaining excess insurance carriers whose policies
generally represent layers of coverage Grace has not yet reached. Such policies
are believed by Grace to be available for asbestos-related personal injury
lawsuits. Insurance coverage for asbestos-related liabilities has not been
commercially available since 1985.

Grace's ultimate exposure with respect to its asbestos-related cases and claims
partly depends on the extent to which its insurance will cover damages for which
it may be held liable, amounts paid in settlements, and litigation costs. In
Grace's opinion, it is probable that recoveries from its insurance carriers
(including amounts reflected in the receivable discussed above), along with
other funds, will be available to satisfy the property damage and personal
injury cases and claims pending at June 30, 1999, as well as personal injury
claims expected to be filed through 2039. Consequently, Grace believes that the
resolution of its asbestos-related litigation will not have a material adverse
effect on its consolidated financial position or results of operations.

For additional information, see Note 2 to the Consolidated Financial Statements
in the 1998 Form 10-K.

3.  DISCONTINUED OPERATIONS
- --------------------------------------------------------------------------------

PACKAGING BUSINESS TRANSACTION

As discussed in Note 1, the Spin-off and the Merger were completed on March 31,
1998. Prior to the Spin-off and the Merger, Old Grace and a Packaging Business
subsidiary borrowed $1,258.8 million (inclusive of $2.2 million of bank fees)
and made a cash transfer of $1,256.6 million to Grace, which used the
transferred funds to repay substantially all of Grace's debt (see Note 5 to the
interim consolidated financial statements in this Report). The borrowed funds
are shown as a net financing activity of discontinued operations in the
Consolidated Statement of Cash Flows in this Report. In the Merger and a related
recapitalization, for each Old Grace common share outstanding at the close of
trading on March 31, 1998, each shareholder received .536 shares of New Sealed
Air common stock and .475 shares of New Sealed Air convertible preferred stock.
Upon the completion of the Spin-off and the Merger, the shareholders of Old
Grace owned (a) 100% of the specialty chemicals businesses (through


                                      I-8
<PAGE>

their ownership of 100% of the Company's outstanding shares) and (b)
approximately 63% of New Sealed Air, on a fully diluted basis.

The Packaging Business transaction resulted in an adjustment to shareholders'
equity of $196.4 million, representing Grace's investment in the Packaging
Business less the $1,258.8 million of borrowings discussed above.

During 1998, Grace made certain amendments to one of its domestic pension plans
which included offering a lump sum settlement option to former Grace employees
not currently receiving benefits. During the second quarter of 1999, a
significant number of the lump sum offers were settled. In accordance with SFAS
No. 88, "Employers' Accounting for Settlements and Curtailments of Defined
Benefit Plans and for Termination Benefits," the Company recognized a pretax
loss of $11.0 million during the three months ended June 30, 1999, in connection
with these settlements. A pretax non-cash charge of $9.1 million ($5.7 million
after-tax) is included in loss from discontinued operations in the Consolidated
Statement of Operations in this Report as it relates to settlements with former
Packaging Business employees. A pretax non-cash charge of $1.9 million is
included in selling, general and administrative expenses in the Consolidated
Statement of Operations in this Report for settlements relating to former Grace
employees not associated with the former Packaging Business.

The Packaging Business transaction also required the Company to split certain
pension plans and recognize a net curtailment loss for other plans. In
accordance with SFAS No. 88, the Company recognized a net pretax loss of $8.4
million ($5.5 million after-tax) for the three months ended March 31, 1998, in
connection with these plans. This net pretax loss is included in loss from
discontinued operations in the Consolidated Statement of Operations in this
Report.

5.  DEBT / EXTRAORDINARY ITEM
- --------------------------------------------------------------------------------

As discussed in Notes 1 and 3 above, Grace received a cash transfer of $1,256.6
million in connection with the Spin-off and Merger. Grace used the transferred
funds to repay substantially all of its debt. On March 31, 1998, Grace used
$600.0 million of the cash transfer to repay bank borrowings. On April 1, 1998,
Grace repaid $611.3 million principal amount of 8.0% Notes Due 2004, 7.4% Notes
Due 2000, and 7.75% Notes Due 2002 (collectively, Notes), pursuant to a tender
offer that expired on March 27, 1998. On April 1, 1998, Grace also repaid $3.5
million principal amount of the Medium-Term Notes, Series A (MTNs) and $6.0
million of sundry indebtedness.


                                      I-10

As a result of this extinguishment of debt, Grace incurred a pretax charge of
$56.3 million ($35.2 million after-tax, or a basic loss per share of $.47;
diluted loss per share of $.43) for premiums paid in excess of the Notes'
principal amounts and other costs incurred in connection with the purchase of
the Notes and MTNs (including the costs of settling related interest rate swap
agreements). These costs are presented as an extraordinary item in the
Consolidated Statement of Operations in this Report. On June 30, 1999, and
December 31, 1998, the Company's short-term and long-term debt was as follows:

In May 1999, Grace entered into a $250.0 million credit facility under a 364-day
credit agreement expiring May 2000. In addition, Grace maintains a $250.0
million long-term facility expiring in May 2003. At June 30, 1999 the Company
had $146.8 million of bank borrowings outstanding under these facilities.

6.  SHAREHOLDERS' EQUITY
- --------------------------------------------------------------------------------

The Company is authorized to issue 300,000,000 shares of common stock. Of the
common stock unissued on June 30, 1999, approximately 14,484,000 shares were
reserved for issuance pursuant to stock options and other stock incentives.

In April 1998, the Company's Board of Directors approved a program to repurchase
up to 20% of the Company's outstanding shares in the open market (approximately
15,165,000 shares). Through June 30, 1999, the Company had acquired 9,379,000
shares of common stock for $138.7 million under the program (an average price
per share of $14.79). In January 1999, Grace retired 5,476,800 shares of
treasury stock with a cost basis of $88.4 million, which is reflected in the
Consolidated Statement of Shareholders' Equity in this Report.

SALES AND REVENUES

Sales and revenues of Grace's continuing business segments increased 0.8% to
$373.0 million in the second quarter of 1999 and increased 1.1% to $718.5
million in the first six months of 1999. Factoring out fluctuations in
currencies compared to the same periods of the prior year, sales and revenues
would have increased an overall 2.6% for the second quarter and 1.7% for the
first six months of 1999.

On an as-reported basis, including currency fluctuations: Grace Davison sales
were essentially flat for the quarter and down 1.5% year-to-date primarily due
to weakened worldwide demand for fluid cracking catalysts (FCC); Grace
Construction Products sales increased 5.0% for the quarter and 7.6% year-to-date
due primarily to customer receptiveness to its new and value-added products;
and, Darex Container Products sales decreased 3.9% for the quarter and 3.7%
year-to-date with price and mix improvements being more than offset by
unfavorable currency exchange, principally in Latin America and Europe. (Refer
to separate sections that follow for business segment discussions of sales and
revenues.)

PRE-TAX OPERATING INCOME

For the second quarter and year-to-date, earnings improvements were realized in
each business segment compared to the respective period of the prior year. Grace
Davison's operating income was up 11.0% versus the prior year quarter and 0.8%
year-to-date. The second quarter saw a reversal of Grace Davison's negative
first quarter income comparison largely due to gross margin improvement through
cost control initiatives that began to show a favorable impact on direct
manufacturing costs in the second quarter. Grace Construction Products'
operating income was up 26.8% for the quarter and 44.1% year-to-date, primarily
attributable to the success of value-added product substitution and penetration
programs coupled with manufacturing cost containment. Darex Container Products'
operating income was up 3.9% versus the prior year quarter and 1.4%
year-to-date. This increase was achieved despite a decline in sales and the
inclusion in the prior year of a $1.5 million gain resulting from the sale of a
can forming lubricants business, primarily due to improved operating margins
from the restructuring and consolidation of its infrastructure. (Refer to
separate sections that follow for business segment discussions of pre-tax
operating income.)

INCOME FROM CONTINUING OPERATIONS

Grace reported income from continuing operations of $31.4 million for the second
quarter, or $0.43 diluted earnings per share, up from $25.5 million, or $0.32
diluted earnings per share in 1998. Year-to-date income from continuing
operations improved 37.8% over the prior year resulting in diluted earnings per
share of $0.70 compared to $0.46 for the six months ended June 30, 1998.

Offsetting improvement in business segment income were increases in corporate
expenses. Contributing factors for the second quarter and year-to-date corporate
expense increase were: a) a non-cash charge of $1.9 million related to a partial
settlement of pension obligations to recognize a proportionate share of
actuarial pension losses (see Note 3 to the interim consolidated financial
statements in this Report); b) the settlement of a lawsuit with the Securities
and Exchange Commission which required the Company to establish a $1.0 million
educational fund for public sector programs to increase awareness and education
relating to financial statements and generally accepted accounting principles;
and c) approximately $1.0 million of relocation and recruitment charges related
to the move of Grace's headquarters from Boca Raton, Florida to Columbia,
Maryland. It is anticipated that additional relocation costs will be incurred
during the second half of 1999.

<PAGE>


Other income, which includes investment income, equity earnings of
non-controlled investees, sales of marketable equity investments and income from
toll manufacturing decreased $2.7 million compared to the second quarter of
1998, primarily due to a decrease in toll manufacturing, as arrangements to
support divested businesses begin to run out. Included in the first six months
results of 1999 was a pretax gain of $4.4 million on the sale of the corporate
aircraft.

Interest expense and related financing costs for the second quarter were $5.1
million or $0.7 million more than the prior year. Such costs for the first six
months of 1999 were $8.9 million, down from $11.2 million for the first six
months of 1998. Average borrowings (including receivables sold) were $81.0
million higher in the second quarter of 1999 compared to 1998, but $459.8
million lower on a year to year basis. Proceeds from the Packaging Business
transaction were used to reduce debt levels in April 1998. Weighted average
borrowing costs were 6.4% year-to-date 1999 versus 7.1% in 1998.

In the first quarter of 1999, Grace recorded a pretax charge of $4.3 million for
incremental restructuring costs for severance related to the productivity
effectiveness program implemented in December 1998. This charge included $2.8
million of severance costs in connection with the relocation of Grace's
headquarters from Boca Raton, Florida to Columbia, Maryland, and the
consolidation of certain administrative functions in Columbia.

Grace's effective tax rate was 37.0%, down from 39.0% in 1998. The decrease in
the tax rate was due to a reorganization of certain Grace foreign operations
resulting in anticipated lower foreign taxes.

NET INCOME/(LOSS)

Net income for the second quarter and first six months of 1999 included a loss
from discontinued operations of $5.7 million. Net loss of $0.5 million in the
first six months of 1998 included a loss from discontinued operations of $2.6
million and an extraordinary loss from early extinguishment of debt of $35.2
million (see Notes 3 and 5 to the interim consolidated financial statements in
this Report).

GRACE DAVISON

Sales and Revenues

Grace Davison is a leading global supplier of catalysts and silica products.
Refining catalysts, representing approximately 55.2% of Grace Davison's
year-to-date total sales, include fluid cracking catalysts (FCC) used by
petroleum refiners to convert distilled crude oil into transportation fuels and
other petroleum-based products, and hydroprocessing catalysts, which upgrade
heavy oils and remove certain impurities. Silica products and adsorbents (29.5%
of Grace Davison's year-to-date total sales) are used in a wide variety of
industrial and consumer applications. Polyolefin catalysts and catalyst supports
(11.3% of Grace Davison's year-to-date total sales) are essential components in
the manufacture of polyethylene resins used in products such as plastic film,
high performance plastic pipe, and plastic household containers.

Grace Davison's sales and revenues were essentially flat compared to the second
quarter of 1998 and down 1.5% for the six-month period. Currency translation had
only a minor impact on second quarter and year-to-date Grace Davison sales.
Volume growth in silicas and adsorbents and polyolefin catalysts was offset by
declines in refining catalyst volume.



                                      I-17
<PAGE>

Refining catalysts sales decreased 4.2% in the second quarter and 5.9%
year-to-date, primarily as a result of volume declines in North America and Asia
Pacific, partially offset by volume gains in Europe. FCC volume decline in North
America was due to reduced refinery usage and excess refinery turnaround
activity. Volume decline in Asia Pacific was primarily due to reduced market
share. Better volumes in Europe were primarily due to increased shipments to
existing and new customers of hydroprocessing catalysts made possible as a
result of new manufacturing capacity coming on line in the third quarter of
1998.

Polyolefin catalysts sales increased 4.1% in the second quarter and 6.4%
year-to-date on strong sales volumes in all geographic regions, except Asia
Pacific. Volume growth is largely driven by a robust polyolefin market
worldwide, particularly in North America.

Silicas and adsorbents sales increased 3.1% for the second quarter and 2.7%
year-to-date as a result of worldwide volume gains, partially offset by
unfavorable price/mix. Pricing pressures for insulated glass molecular sieves
were offset by volume growth in the dentifrice, coatings and plastics segments.

Pre-Tax Operating Income

Grace Davison's pre-tax operating income increased 11.0% over the second quarter
1998 with a year-to-date increase of 0.8%. Gross margins improved in the second
quarter, despite virtually flat sales, as a result of this business segment
beginning to realize raw material cost reductions and manufacturing efficiencies
from Grace's productivity effectiveness program. This program is designed to
lower manufacturing and other operating expenses. These improvements were
partially offset by restructuring costs of $0.9 million recognized in the first
quarter of 1999.

GRACE CONSTRUCTION PRODUCTS

Sales and Revenues

Grace Construction Products is a leading supplier of specialty chemicals and
building materials to the nonresidential (commercial and government)
construction industry and to a lesser extent, the residential construction
industry. Specialty construction chemicals, which contributed approximately
58.1% of Grace Construction Products year-to-date total sales, add strength,
control corrosion, and enhance the handling and application of concrete.
Specialty building materials prevent water damage to structures and protect
structural steel against collapse due to fire.

Grace Construction Products' sales and revenues increased 5.0% over the second
quarter of 1998 bringing the aggregate year-to-date increase to 7.6% over the
prior year. Currency translation had only a minor impact on second quarter and
year-to-date sales.

Specialty construction chemicals sales increased 5.7% for the second quarter and
8.1% year-to-date, driven by volume increases across all regions. In North
America, volume increased 4.3% in the second quarter and 6.6% for the six months
due to continued penetration of value-added products. In Asia Pacific, sales
increased 17.0% for the second quarter and 14.5% year-to-date due to the
consolidation of a joint venture in Japan (GCK), as Grace increased its
ownership in this joint venture from 45% to 81% in January 1999.

Specialty building materials sales increased 4.2% for the second quarter due to
higher volumes in North America, as a result of value-added product penetration,
partially offset by decreased volumes in Asia


                                      I-18
<PAGE>

Pacific due to continued depressed project activity. The year-to-date increase
of 7.0% is also attributable to higher volumes in North America coupled with a
positive volume growth in Asia Pacific during the first quarter of 1999.

Pre-Tax Operating Income

Grace Construction Products' pre-tax operating income for the second quarter and
first six months of 1999 was 26.8% and 44.1% better than the same periods in
1998, driven by sales increases and margin improvements from value-added product
penetration/substitution and manufacturing cost reduction. Total operating
expenses increased due to the consolidation of GCK, offset by savings generated
from Grace's productivity effectiveness program. These improvements were
partially offset by restructuring costs of $0.3 million recognized in the first
quarter of 1999 from the implementation of such program.

DAREX CONTAINER PRODUCTS

Sales and Revenues

Darex Container Products is a leading global producer of can sealants, closure
sealants, coatings for metal packaging, and other related products. Can
sealants, which represent approximately 50.8% of Darex year-to-date total sales,
hermetically seal beverage, food, and other cans; closure sealants (13.9% of
year-to-date total sales) seal glass and plastic bottles and jars used in
beverage and food applications; and coatings (18.9% of year-to-date total sales)
protect metal packaging from corrosion and its contents from the influences of
the metal.

Darex Container Products' sales and revenues were 3.9% and 3.7% lower than the
comparable second quarter and year-to-date periods in 1998. Contributing to the
sales decline was the May 1998 divestment of a can forming lubricants business,
which had sales of $0.6 million in the second quarter and $1.6 million in the
first six months of 1998. Also contributing to the sales declines was the
overall adverse impact of currency weakness in Europe and Latin America compared
to the value of the U.S. dollar. The negative impact of foreign currency
translation was $3.3 million for the second quarter and $4.4 million for the
first six months of 1999. Excluding the impact of these items, sales would have
increased by 2.4% for the quarter and 1.1% year-to-date.

Can sealant sales were down 3.7% for the quarter and 5.0% for the first six
months due to customer consolidations and the impact of currency movements,
offset by increased volume in Asia Pacific and a favorable price/mix variance in
Europe and Latin America. Worldwide, closure sealants sales decreased 4.2% for
the quarter and were essentially flat year-to-date, as higher sales of PVC and
non-PVC applications in Europe were offset by lower sales in Asia Pacific and
unfavorable currency exchange. Coatings were down 8.9% for the quarter and 3.6%
for the six months as volume increases in Asia Pacific were offset by volume
decreases in Latin America and Europe as well as unfavorable currency exchange.

Pre-Tax Operating Income

Darex Container Products' pre-tax operating income increased by 3.9% for the
second quarter and 1.4% for the first six months of 1999. Excluding the gains
resulting from sale of the can forming lubricants business ($0.3 million in 1999
and $1.5 million in 1998) and the currency translation effect, pretax operating
income would have increased by 33.4% for the quarter and 16.7% for the six
months. Continued productivity initiatives, principally restructuring and
consolidation of infrastructure, resulted in reduced


                                      I-19
<PAGE>

operating, selling and research and development expenses and slight improvements
in gross margin. Year-to-date results include restructuring costs of $0.3
million recognized in the first quarter of 1999 from the implementation of
Grace's productivity improvement program.

DISCONTINUED OPERATIONS
- --------------------------------------------------------------------------------

PACKAGING BUSINESS

As discussed in Notes 1 and 3 to the interim consolidated financial statements
in this Report, the Spin-off and Merger were completed on March 31, 1998.
Results from discontinued operations for the six months ended June 30, 1999
included $9.1 million ($5.7 million after-tax) for a related pension plan
settlement loss, and for the six months ended June 30, 1998 included $32.6
million ($28.3 million after-tax) of costs related to the Packaging Business
transaction and $8.4 million ($5.5 million after-tax) for a related pension plan
curtailment loss.

- --------------------------------------------------------------------------------
FINANCIAL CONDITION
- --------------------------------------------------------------------------------

LIQUIDITY AND CAPITAL RESOURCES

Grace's continuing operating activities provided net pretax cash of $57.7
million in the first six months of 1999, compared to using $235.5 million in the
first six months of 1998. After giving effect to the net pretax cash used by
operating activities of discontinued operations and payments of income taxes,
the net cash used by operating activities was $19.3 million in the first six
months of 1999 compared to $314.6 million for the same period in 1998. The
decrease from the first six months of 1998 was primarily due to expenditures of
$70.3 million in the first six months of 1999 for the defense and disposition of
asbestos-related litigation, partially offset by $40.6 million received from
settlements with certain insurance carriers in connection with such litigation,
as compared to the net expenditure of $141.4 million for asbestos-related
litigation in the first six months of 1998. In addition, environmental
remediation payments totaled $15.0 million for the first six months of 1999
compared to $28.3 million in the first six months of 1998. There was also
approximately $100.5 million decrease in long-term incentive compensation
program disbursements in the first six months of 1999 compared to 1998. The
long-term incentive compensation program has been discontinued going forward.
Future disbursements on the runoff of existing plans will total less than $5.0
million over the next two years. Tax payments totaled $59.1 million compared to
$27.8 million reflecting payments of previously established tax liabilities for
open tax years under IRS examination.

Cash used for investing activities in the first six months of 1999 was $16.1
million, compared to $51.0 million in the first six months of 1998. The 1999
cash outflows for capital expenditures primarily relate to continued deployment
of new information technology and added manufacturing equipment, principally at
Grace Davison. Grace anticipates that total 1999 capital expenditures will be
approximately $90.0 million, most of which will be directed towards its business
segments and for capital improvement costs related to the 1999 move of the
corporate headquarters to Columbia, Maryland.

Net cash provided by financing activities in the first six months of 1999 was
$29.5 million. A portion of the short-term borrowings of $68.5 million were used
to purchase $56.6 million of the Company's shares as part of the 1998 share
repurchase program. Net cash provided by financing activities in the first six
months of 1998 was $392.7 million, primarily reflecting the cash transfer of
$1,256.6 million received in


                                      I-20
<PAGE>

connection with the Packaging Business transaction and proceeds from the
exercise of employee stock options, partially offset by net repayments of
borrowings.

In connection with the Packaging Business transaction, Grace received $1,256.6
million in cash, which was used to repay substantially all of its debt. On March
31, 1998, Grace used $600.0 million of the cash transfer to repay bank
borrowings. On April 1, 1998, Grace repaid $611.3 million principal amount of
Notes pursuant to a tender offer that expired on March 27, 1998. On April 1,
1998, Grace also repaid $3.5 million principal amount of MTNs and $6.0 million
of sundry indebtedness. As a result of this extinguishment of debt, Grace
incurred an after-tax charge of $35.2 million for premiums paid in excess of the
Notes' principal amounts and other costs related to the purchase of the Notes
and MTNs (including the costs of settling related interest rate swap
agreements). These costs are presented as an extraordinary item in the
Consolidated Statement of Operations in this Report.

On June 30, 1999, Grace had committed borrowing facilities totaling $500.0
million, consisting of $250.0 million expiring in May 2000 and $250.0 million
under a long-term facility expiring May 2003. These facilities support the
issuance of commercial paper and bank borrowings, of which $146.8 million was
outstanding on June 30, 1999. The aggregate amount of net unused and unreserved
borrowings under short-term facilities at June 30, 1999 was $353.2 million.

In addition, Grace has an agreement to sell, on an ongoing basis, an approximate
$100 million pool of eligible trade accounts receivable to a multi-seller
receivables company (the "conduit") through a wholly-owned bankruptcy-remote
special purpose subsidiary. Cash proceeds, net of remittances to the conduit for
collections, received during the first six months of 1999 were $38.4 million and
through June 30, 1999 aggregated $75.4 million since program inception.

Grace has targeted a ratio of debt to EBITDA (earnings before interest, taxes,
depreciation and amortization and special charges - as defined in Grace's
borrowing facilities) of 1 to 1. However, Grace will consider exceeding this
target as business needs dictate. The debt to EBITDA ratio for the six months
ended June 30, 1999 was estimated at .67 to 1.

In April 1998, the Company's Board of Directors approved a program to repurchase
up to 20% of the Company's outstanding shares in the open market (approximately
15,165,000 shares). Through June 30, 1999, the Company had acquired 9,379,000
shares of common stock for $138.7 million under the program (an average price
per share of $14.79).

Grace believes that cash flows generated from future operations and committed
borrowing facilities will be sufficient to meet its cash requirements for the
foreseeable future.

ASBESTOS-RELATED MATTERS

In the first six months of 1999, Grace paid $29.7 million for the defense and
disposition of asbestos-related property damage and personal injury litigation,
net of amounts received under settlements with insurance carriers. Although the
total amount to be paid in 1999 with respect to asbestos-related claims (after
giving effect to payments to be received from insurance carriers) cannot be
precisely estimated, Grace currently expects that it will expend approximately
$40.0-$70.0 million (pretax) in 1999 to defend against and dispose of such
claims. Such amounts are estimates of the probable cost of defending against and
disposing of asbestos-related claims and probable recoveries from insurance
carriers and are on an undiscounted basis - the ultimate outcomes of such
matters cannot be predicted with certainty and estimates may change as actual
experience evolves over time.

See Note 2 to the interim consolidated financial statements in this Report for
further information concerning asbestos-related lawsuits and claims.

ENVIRONMENTAL MATTERS

There were no new or significant developments relating to environmental
liabilities in the first six months of 1999.

For additional information relating to environmental liabilities, see Note 11 to
the Consolidated Financial Statements in the 1998 10-K.

- --------------------------------------------------------------------------------
YEAR 2000 COMPUTER SYSTEMS COMPLIANCE
- --------------------------------------------------------------------------------

OVERVIEW

Grace has reviewed its Year 2000 compliance efforts by business segment. Each
business segment and Grace Corporate has appointed a project leader to
coordinate a comprehensive review of all systems used by Grace to determine to
what extent Grace may be affected by the failure of its systems to be Year 2000
compliant. In addition, the project leader for Grace Corporate also functions as
Grace's overall Project Director, reporting directly to the Chief Executive
Officer.

Grace is reviewing both its information technology ("IT") and non-information
technology ("non-IT") systems for Year 2000 compliance. IT systems include
hardware, infrastructure, local and wide area networks, software, application
systems, electronic data exchange and interfaces. Non-IT systems cover process
control and manufacturing support equipment, laboratory systems, instruments and
scales, telecommunications, and facility and utility support systems. Non-IT
systems include systems containing date dependent software as well as embedded
date dependent chip technology.

GRACE'S CURRENT STATE OF YEAR 2000 READINESS

INVENTORY

Grace has completed an inventory of its IT and non-IT systems that could
potentially be affected by the Year 2000 issue for each of its business segments
and Grace Corporate. All systems have been prioritized as being either critical
or non-critical. A critical system is one where failure to be Year 2000
compliant may have a material adverse effect on health and safety, the
environment or on Grace's financial condition or results of operations. A
non-critical system is one where failure to be Year 2000 compliant could produce
brief business interruptions or system failures that may be remedied promptly
and that are not reasonably likely to have any such material adverse effect.

COMPLIANCE

As of June 30, 1999, 92% of the critical items are Year 2000 compliant and 8%
are non-compliant. The non-compliant critical items include a laboratory
information system, an upgrade to a waste water treatment control system,
laboratory equipment, Grace electronic mail systems, a stock option processing
system, and non-compliant personal computers and software applications at
certain business segment locations. All of the remaining 8% of non-compliant
critical items are expected to be remediated prior to October 31, 1999 (as
compared to the mid-1999 date as was previously estimated), except for the stock


                                      I-22
<PAGE>

option processing system. This system is in the process of being outsourced. If
the system is not successfully outsourced by the end of 1999, then the stock
option process will be performed manually by the outsourcing firm.

As of June 30, 1999, 59% of non-critical items are known to be compliant, 16%
are non-compliant, with the compliance status of the remaining 25% of items
being unknown. Grace will have contingency plans in place for any non-critical
systems that have not been remediated by the end of 1999. Remediation for
non-critical items will take place throughout 1999 and into 2000.

For non-IT systems, Grace's most significant internal Year 2000 exposure is with
the process control systems that control the major Grace Davison plants. The
hardware and system operating and application software associated with these
systems have been assessed by the primary vendors providing these systems, and
all but one system has been confirmed as being Year 2000 compliant by these
vendors and, where appropriate, by internal testing. The remaining non-compliant
system, which is scheduled to be replaced prior to September 1, 1999, is a
wastewater treatment system.

Grace Construction Products' facilities primarily utilize a batch process
approach for manufacturing and have limited automated process controls that may
be directly impacted by Year 2000 issues. Darex Container Products has more than
20 manufacturing facilities worldwide and certain facilities have automated
process controls. All critical process control systems for both Grace
Construction Products and Darex Container Products have been reviewed using
compliance information provided by their vendors and, where appropriate,
internal testing, and all have been confirmed as Year 2000 compliant.

Grace has contacted its key customers and vendors (including telecommunications
and utility providers, banks and governmental agencies) in an effort to
ascertain their compliance status. Through June 30, 1999, 88% of key vendors and
74% of key customers had returned or made available to Grace information on
their compliance status. Grace is analyzing these responses and following up on
an on-going basis with those key vendors and customers who have not responded or
whose responses are not adequate. Based on the responses received to date, Grace
does not believe that the non-compliance of key customers will have a material
adverse effect on Grace's financial condition or results of operations. However,
Grace believes that widespread non-compliance by certain vendors such as utility
providers could have a material adverse effect and is developing contingency
plans to the extent they will be effective to address such non-compliance as
described under "Contingency Plans" below.

REMEDIATION AND TESTING

Grace has documented remediation and validation testing plans in place for the
remaining 8% of non-compliant critical IT and non-IT items and expects to have
completed the remediation of all such remaining items prior to October 31, 1999,
with the exception of the stock option processing system, as described in the
Compliance section above. Remediation for non-critical items will take place
throughout 1999 and into 2000. Grace will have contingency plans in place for
any non-critical systems that have not been remediated by the end of 1999.

Grace primarily uses internal resources to validate the remediation procedures
as they relate to critical IT and non-IT systems. The Grace Year 2000 Project
Director reviews the Grace Year 2000 effort on an on-going basis, reporting
regularly to the Audit Committee of the Board of Directors of Grace.

A major component of Grace's IT remediation activity is in place as a result of
the conversion of its financial and certain operational support systems to
programs using software of SAP America, Inc.

                                      I-23
<PAGE>


(SAP), which has represented that its systems used by Grace are Year 2000
compliant. Unrelated to its Year 2000 efforts, Grace commenced this project in
1995. Grace Construction Products and Darex Container Products have completed
the implementation of the SAP software in North America and many countries
throughout the rest of the world, and expect to complete the implementation in
the remaining countries by September 30, 1999.

Grace Davison is implementing SAP in conjunction with Grace Construction
Products and Darex Container Products in Asia Pacific and Latin America,
respectively. In North America and Europe, Grace Davison will not convert to SAP
until after December 31, 1999. In North America, Grace Davison has installed new
software releases to upgrade existing systems and has contracted with outside
programming services to resolve its Year 2000 issues. All such systems in North
America are now fully remediated, tested and confirmed as being Year 2000
compliant. In Europe, Grace Davison uses a largely internally developed software
program that is now supported and maintained by a third party, to provide its
business and financial systems support. This third party vendor has provided
Grace Davison with a version of system software that has been tested and
confirmed as being Year 2000 compliant.

COSTS

Grace estimates as of June 30, 1999, the total cost of its Year 2000 efforts is
not expected to exceed $4.6 million, of which approximately $2.2 million has
been spent to date. The largest portion of the remaining expenditures is for
replacement costs for non-compliant laboratory equipment and personal computers.

The total cost excludes the cost of the SAP implementation since, despite being
a critical component of the Grace Year 2000 remediation effort, this was a
project that was already planned and was not accelerated due to Year 2000
issues. This amount also excludes internal costs, principally the payroll costs,
of IT personnel not solely devoted to the Year 2000 remediation effort. No
material IT or non-IT projects were delayed due to the Grace Year 2000
remediation effort.

CONTINGENCY PLANS

Grace is in the process of developing and evaluating various contingency plans
to cover Year 2000 failures. For IT systems, Grace is considering closing of the
financial books as of midnight on December 30, 1999, since December 31 is
considered a company holiday, designing a means to enter data into key Grace
information systems in the event of telecommunication failure in certain
countries, and using diesel generators in the case of power failure at key data
processing facilities. For non-IT systems plans include building up inventories
and, where possible, identifying alternative manufacturing locations for
product. One key Grace plant already has its own power generation capability.

RISK

If Grace fails to take appropriate remedial action, Year 2000 non-compliance
could have a material adverse effect on the financial condition or results of
operations of Grace. However, Grace believes that the efforts being taken to
ensure Year 2000 compliance outlined above, together with contingency planning,
will be effective to minimize interruptions or loss of business, or
environmental, health and safety risks. One possible exception to this
conclusion is in the case of widespread or extended infrastructure failures by
utility providers (power, water, gas, etc.) at key Grace manufacturing
locations. Widespread infrastructure failure or extended infrastructure failure
at these sites could affect the ability of Grace to manufacture products and
meet the demands of its customers.


                                      I-24
<PAGE>


The foregoing Year 2000 discussion is based on management's current evaluation
using available information. Factors that might cause material changes include,
but are not limited to, the readiness of third parties and Grace's ability to
respond to unforeseen Year 2000 complications.

                for information concerning an action filed by the Securities and
                Exchange Commission ("SEC") charging that from 1991 through 1995
                Grace deferred reporting income earned by a subsidiary,
                primarily to smooth earnings of its former health care group in
                violation of the antifraud, reporting and books and records
                provisions of the Securities and Exchange Act of 1934. On June
                30, 1999, Grace confirmed that it had reached agreement with the
                SEC on a settlement of the SEC's charges. Under the settlement,
                Grace consented to a cease and desist order without admitting or
                denying the SEC's findings. Grace also agreed to establish a $1
                million fund to be used for programs in the public sector to
                further awareness and education relating to financial statements
                and generally accepted accounting principles.

         (c)    Reference is made to the section entitled "U.S. Justice
                Department Lawsuit" in Item 3 of Grace's 1998 Form 10-K for
                information concerning a lawsuit alleging that Baker & Taylor
                Books, a book wholesaler sold by Grace in 1992, overcharged
                public schools, libraries, and federal agencies over a ten year
                period (now identified as 1985 to 1995). During the second
                quarter of 1999, Baker & Taylor, Inc. (the entity that currently
                owns Baker & Taylor Books) entered into a separate settlement
                with the United States Government. The case continues with
                claims by the United States against Grace and by the State of
                California against Grace and Baker & Taylor, Inc.

         364-DAY CREDIT AGREEMENT, dated as of May 5, 1999, among W. R. GRACE &
CO.-CONN., a Connecticut corporation (the "Company"), W. R. GRACE & CO.
(formerly named Grace Specialty Chemicals, Inc.), a Delaware corporation (the
"Parent"), the several banks from time to time parties to this Agreement (the
"Banks"), BANK OF AMERICA NATIONAL TRUST AND SAVINGS ASSOCIATION, a national
bank, as documentation agent (in such capacity, the "Documentation Agent"), THE
CHASE MANHATTAN BANK, a New York banking corporation, as administrative agent
for the Banks hereunder (in such capacity, the "Administrative Agent") and CHASE
SECURITIES INC., as book manager (in such capacity, the "Book Manager").

         The parties hereto hereby agree as follows:

         SECTION 1. DEFINITIONS

         1.1 Defined Terms. As used in this Agreement, the following terms shall
have the following meanings:

         "ABR Loans": Loans the rate of interest applicable to which is based
    upon the Alternate Base Rate.

         "Additional Bank": as defined in subsection 2.4(b).

         "Affiliate": as to any Person, (a) any other Person (other than a
    Subsidiary) which, directly or indirectly, is in control of, is controlled
    by, or is under common control with, such Person or (b) any Person who is a
    director, officer, shareholder or partner (i) of such Person, (ii) of any
    Subsidiary of such Person or (iii) of any Person described in the preceding
    clause (a). For purposes of this definition, "control" of a Person means the
    power, directly or indirectly, either to (i) vote 10% or more of the
    securities having ordinary voting power for the election of directors of
    such Person or (ii) direct or cause the direction of the management and
    policies of such Person whether by contract or otherwise.

         "Aggregate Outstanding Bilateral Option Loans": at any time, (i) the
    aggregate outstanding principal amount of all Dollar Bilateral Loans and
    (ii) the aggregate Dollar Equivalents at such time with respect to all
    outstanding Alternative Currency Bilateral Loans.

         "Agreement": this 364-Day Credit Agreement, as the same may be amended,
    supplemented or otherwise modified from time to time.

         "Alternate Base Rate": for any day, a rate per annum (rounded upwards,
    if necessary, to the next 1/16 of 1%) equal to the greater of (a) the Prime
    Rate in effect on such day and (b) the Federal Funds Effective Rate in
    effect on such day plus 1/2 of 1%. "Prime Rate" shall mean the rate of
    interest per annum publicly announced from time to time by the
    Administrative Agent as its prime rate in effect at its principal office in
    New


<PAGE>

                                                                             2

    York City. "Federal Funds Effective Rate" shall mean, for any day, the
    weighted average of the rates on overnight federal funds transactions with
    members of the Federal Reserve System arranged by federal funds brokers, as
    published on the next succeeding Business Day by the Federal Reserve Bank of
    New York, or, if such rate is not so published for any day which is a
    Business Day, the average of the quotations for the day of such transactions
    received by the Administrative Agent from three federal funds brokers of
    recognized standing selected by it. If for any reason the Administrative
    Agent shall have determined (which determination shall be conclusive absent
    manifest error) that it is unable to ascertain the Federal Funds Effective
    Rate, for any reason, including, the inability or failure of the
    Administrative Agent to obtain sufficient quotations in accordance with the
    terms hereof, the Alternate Base Rate shall be determined without regard to
    clause (b) of the first sentence of this definition until the circumstances
    giving rise to such inability no longer exist. Any change in the Alternate
    Base Rate due to a change in the Prime Rate or the Federal Funds Effective
    Rate shall be effective on the effective date of such change in the Prime
    Rate or the Federal Funds Effective Rate, respectively.

         "Alternative Currency": any currency other than Dollars which is freely
    transferable and convertible into Dollars.

         "Alternative Currency Bilateral Loan": a Loan made by a Bank to any
    Borrower in an Alternative Currency pursuant to Section 3.

         "Applicable Margin": for any day on which the long term senior
    unenhanced, unsecured debt of the Company is rated by both S&P and Moody's,
    the rate per annum under the caption "Margin" (a "Margin Rate") set forth
    below opposite the S&P and Moody's ratings applicable to such debt on such
    day (or, if such ratings are set opposite two different Margin Rates, then
    the Applicable Margin shall be the lower of said two Margin Rates):

         Margin           S&P                    Moody's
         ------           ---                    -------

          .750%         BB or lower            Ba2 or lower

          .675%         BB+                    Ba1

          .450%         BBB-                   Baa3

          .350%         BBB or higher          Baa2 or higher

    provided that if on any day (i) the long term senior unenhanced, unsecured
    debt of the Company is rated by only one of either S&P or Moody's, the
    Applicable Margin will be determined based on the rating by such rating
    agency, (ii) the long term senior unenhanced, unsecured debt of the Company
    is rated by neither S&P nor Moody's, the Applicable Margin will be
    determined based on the rating of such debt by Duff & Phelps,

    Fitch or another nationally recognized statistical rating organization
    agreed to by and among the Company, the Administrative Agent and the
    Majority Banks (each, a "Substitute Rating Agency") and will be the Margin
    Rate set forth above opposite the S&P and Moody's ratings comparable to such
    Substitute Rating Agency's rating of such debt on such date and (iii) the
    long term senior unenhanced, unsecured debt of the Company is rated by none
    of S&P, Moody's or any Substitute Rating Agency, the Company, the
    Administrative Agent and the Banks will negotiate in good faith to determine
    an alternative basis for calculating the Applicable Margin consistent with
    the table set forth above and, if agreement on such alternative basis is not
    reached within 30 days, the Applicable Margin will be calculated on an
    alternative basis determined by the Administrative Agent and the Banks in
    their reasonable discretion consistent with the table above, and until such
    alternative basis is determined the Applicable Margin will be the Applicable
    Margin last determined as provided in the table above; and provided,
    further, that (a) if on any day the aggregate Loan Outstandings of all of
    the Banks plus the Aggregate Outstanding Bilateral Option Loans is greater
    than 25% of the Commitments but less than or equal to 50% of the
    Commitments, the Applicable Margin in effect on each such day shall be
    increased by .125% or (b) if on any day the aggregate Loan Outstandings of
    all of the Banks plus the Aggregate Outstanding Bilateral Option Loans is
    greater than 50% of all of the Commitments, the Applicable Margin in effect
    on each such day shall be increased by .25%.

         "Available Commitment": as to any Bank at any time, an amount equal to

Banks not less than 45 days and not more than 60 days prior to the Termination
Date then in effect ("Existing Termination Date"), that the Termination Date be
extended, which notice shall specify a date (which shall be the Existing
Termination Date) as of which the requested extension is to be effective (the
"Effective Date"), and the new Termination Date to be in effect following such
extension (the "Requested Termination Date"), which date shall be no more than
364 days after the effectiveness of such extension (with the Effective Date
being counted as the first day). Each Bank shall, not later than a date 30 days
prior to the Effective Date, notify the Company and the Administrative Agent of
its election to extend or not to extend the Termination Date with respect to its
Commitment. Notwithstanding any provision of this Agreement to the contrary, any
notice by any Bank of its willingness to extend the Termination Date with
respect to its Commitment shall be revocable by such Bank in its sole and
absolute discretion at any time more than 30 days prior to the Effective Date.
Any Bank which shall not timely notify the Company and the

                                                                              16



Administrative Agent of its election to extend the Termination Date shall be
deemed to have elected not to extend the Termination Date with respect to its
Commitment.

         (b) If any one or more Banks shall timely notify the Company and the
Administrative Agent pursuant to paragraph (a) of this subsection 2.4 of their
election not to extend their Commitments or shall be deemed to have elected not
to extend their Commitments, (such Banks being called "Terminating Banks"), then
the Company may (i) designate from the Banks other than Terminating Banks (the
"Continuing Banks") one or more such Continuing Banks to increase their
Commitments, which Continuing Banks shall have given notice to the Company and
the Administrative Agent of their willingness to so increase their Commitments,
(ii) with notice to the Administrative Agent, designate one or more other
banking institutions willing to extend Commitments until the Requested
Termination Date (any such banking institution, an "Additional Bank"), or (iii)
any combination thereof, the aggregate amount of the increases of such
Continuing Banks' Commitments and the amount of such Additional Banks'
Commitments not to exceed the aggregate of the Commitments of the Terminating
Banks. Any such increase in the Commitment of a Continuing Bank shall be
evidenced by a written instrument executed by such Continuing Bank, the Company
and the Administrative Agent, and shall take effect on the Existing Termination
Date. Any Additional Bank shall, on the Existing Termination Date, execute and
deliver to the Company and the Administrative Agent a "Commitment Transfer
Supplement", satisfactory to the Company and the Administrative Agent, setting
forth the amount of such Additional Bank's Commitment and containing its
agreement to become, and to perform all the obligations of, a Bank hereunder,
and the Commitment of such Additional Bank shall become effective on the
Existing Termination Date.

         (c) The Company and each other Borrower, if any, shall deliver to each
Continuing Bank and each Additional Bank which shall have requested Revolving
Credit Notes pursuant to subsection 2.2(c), on the Existing Termination Date in
exchange for each Revolving Credit Note, if any, of each of the Borrowers held
by such Bank, new Revolving Credit Notes, maturing on the Requested Termination
Date, in the principal amount of such Bank's Commitment after giving effect to
the adjustments made pursuant to this subsection 2.4.

         (d) If some of or all the Banks shall have elected to extend their
Commitments as provided in this subsection 2.4, then (i) the Commitments of the
Continuing Banks and any Additional Banks shall continue until the Requested
Termination Date specified in the notice from the Company, and as to such Banks
the term "Termination Date", as used herein shall on and after the Effective
Date mean such Requested Termination Date; (ii) the Commitments of the
Terminating Banks shall continue until the Termination Date in effect prior to
such extension, and shall then terminate, and as to the Terminating Banks, the
term "Termination Date", as used herein, shall continue to mean such Existing
Termination Date; and (iii) from and after the Termination Date in effect prior
to such extension, the term "Banks" shall be deemed to include the Additional
Banks.

         SECTION 3. BILATERAL OPTION LOANS

         3.1 Requests for Offers. (a) From time to time during the period from
the Closing Date until the Termination Date, any Borrower may request any or all
of the Banks (each such Bank to which such a request is made, a "Requested
Bank") to make offers to make Bilateral Option Loans, provided that immediately
after making any such Bilateral Option Loan, the aggregate Loan Outstandings of
all the Banks plus the Aggregate Outstanding Bilateral Option Loans will not
exceed the aggregate Commitments. Any such request shall specify the principal
amount and maturity date of the Bilateral Option Loans for which such Borrower
is requesting offers, whether such Bilateral Option Loans are requested to be
Dollar Bilateral Loans or Alternative Currency Bilateral Loans, the time by
which offers to make such Bilateral Option Loans must be made by such Requested
Bank and by which such offers shall be accepted or rejected by such Borrower,
and if all or any part of the requested Bilateral Option Loans are requested to
be made as Alternative Currency Bilateral Loans, the Alternative Currency to be
applicable thereto. Each Requested Bank may, but shall have no obligation to,
make such offers on such terms and conditions as are satisfactory to such
Requested Bank, and such Borrower may, but shall have no obligation to, accept
any such offers. No Bilateral Option Loan may mature after the Termination Date.

         (b) Each Borrower and Requested Bank shall separately agree as to the
procedures, documentation, lending office and other matters relating to any
Bilateral Option Loan.

         3.2 Reports to Administrative Agent; Determination of Dollar
Equivalents. (a) The Borrower shall deliver to the Administrative Agent a report
in respect of each Bilateral Option Loan (a "Bilateral Option Loan Report") by
2:00 P.M. (New York City time) on the date on which the applicable Borrower
accepts any Bilateral Option Loan, on the date on which any principal amount
thereof is repaid prior to the scheduled maturity date, or on the scheduled
maturity date if payment thereof is not made on such scheduled maturity date,
specifying for such Bilateral Option Loan the date on which such Bilateral
Option Loan was or will be made, such amount of principal is or will be repaid
or such payment was not made as the case may be; in the case of Alternative
Currency Bilateral Loans, the Alternative Currency thereof; and the principal
amount of such Bilateral Option Loan or principal prepayment or repayment or the
amount paid (in the case of any Alternative Currency Bilateral Loan, expressed
in the Alternative Currency therefor).

         (b) Upon receipt of a Bilateral Option Loan Report with respect to the
acceptance of a Bilateral Option Loan, the Administrative Agent shall determine
the Dollar Equivalent thereof.

         (c) If on any Borrowing Date on which after giving effect to the Loans
made on such date, the sum of the aggregate Loan Outstandings of all the Banks
plus the Aggregate Outstanding Bilateral Option Loans exceeds 85% of the
aggregate Commitments, then the Administrative Agent shall redetermine as of
such Borrowing Date, on the basis of the most recently delivered Bilateral
Option Loan Report for each Bilateral Option Loan, the Dollar



<PAGE>

                                                                              18


Equivalent of each Alternative Currency Bilateral Loan then outstanding. In
addition, for so long as the condition specified in the preceding sentence
remains in effect, the Administrative Agent shall determine, at the end of each
fiscal quarter of the Company, on the basis of the most recently delivered
Bilateral Option Loan Report for each Bilateral Option Loan, the Dollar
Equivalent of each Alternative Currency Bilateral Loan then outstanding.

         (d) The Administrative Agent shall promptly notify the Company of each
Dollar Equivalent under this subsection 3.2.

         3.3 Judgment Currency. If for the purpose of obtaining judgment in any
court, it is necessary to convert a sum due from any Borrower hereunder or under
any of the Notes in the currency expressed to be payable herein or under the
Notes (the "specified currency") into another currency, the parties hereto
agree, to the fullest extent that they may effectively do so, that the rate of
exchange used shall be that at which in accordance with normal banking
procedures the Administrative Agent could purchase the specified currency with
such other currency at the Administrative Agent's New York office on the
Business Day preceding that on which final judgment is given. The obligations of
each Borrower in respect of any sum due to any Bank or the Administrative Agent
hereunder or under any Note shall, notwithstanding any judgment in a currency
other than the specified currency, be discharged only to the extent that on the
Business Day following receipt by such Bank or the Administrative Agent (as the
case may be) of any sum adjudged to be so due in such other currency such Bank
or the Administrative Agent (as the case may be) may in accordance with normal
banking procedures purchase the specified currency with such other currency; if
the amount of the specified currency so purchased is less than the sum
originally due to such Bank or the Administrative Agent, as the case may be, in
the specified currency, each Borrower agrees, to the fullest extent that it may
effectively do so, as a separate obligation and notwithstanding any such
judgment, to indemnify such Bank or the Administrative Agent, as the case may
be, against such difference, and if the amount of the specified currency so
purchased exceeds:

         (a) the sum originally due to any Bank or the Administrative Agent, as
the case may be, and

         (b) any amounts shared with other Banks as a result of allocations of
such excess as a disproportionate payment to such Bank under subsection 13.7,

such Bank or the Administrative Agent, as the case may be, agrees to remit such
excess to the applicable Borrower.

         3.4 Repayments. Each Borrower shall repay to each Bank which has made a
Bilateral Option Loan on the maturity date of each Bilateral Option Loan (such
maturity date being that specified in the documentation referred to in
subsection 3.1(a)) the then unpaid principal amount of such Bilateral Option
Loan.

                                                                              19


         SECTION 4. BID LOANS

         4.1 The Bid Loans. Any Borrower may borrow Bid Loans from time to time
on any Business Day during the period from the Closing Date until the
Termination Date, in the manner set forth in this Section 4 and in amounts such
that the aggregate Loan Outstandings of all the Banks at any time plus the
Aggregate Outstanding Bilateral Option Loans at such time will not exceed the
aggregate Commitments at such time, and provided, further, that no such Bid Loan
shall be made if, after giving effect thereto, any Bid Loans would mature after
the Termination Date.

         4.2 Procedure for Bid Loans. (a) A Borrower shall request Bid Loans by
delivering a Bid Loan Request to the Administrative Agent, in writing, by
facsimile transmission, or by telephone, confirmed by facsimile transmission,
not later than 1:00 P.M. (New York City time) one Business Day prior to the
proposed Borrowing Date. Each Bid Loan Request may solicit bids for Bid Loans in
an aggregate principal amount of $5,000,000 or a whole multiple of $1,000,000 in
excess thereof and for not more than three alternative maturity dates for such
Bid Loans. The Administrative Agent shall promptly notify each Bank by facsimile
transmission of the contents of each Bid Loan Request received by it.

         (b) Upon receipt of notice from the Administrative Agent of the
contents of a Bid Loan Request, any Bank that elects, in its sole discretion, to
do so, shall irrevocably offer to make one or more Bid Loans at a rate of
interest determined by such Bank in its sole discretion for each such Bid Loan.
Any such irrevocable offer shall be made by delivering a Bid Loan Offer to the
Administrative Agent, by telephone, immediately confirmed by facsimile
transmission, before 9:30 A.M. (New York City time) on the proposed Borrowing
Date, setting forth the maximum amount of Bid Loans for each maturity date, and
the aggregate maximum amount for all maturity dates, which such Bank would be
willing to make (which amounts may, subject to subsection 4.1, exceed such
Bank's Commitments) and the rate of interest at which such Bank is willing to
make each such Bid Loan; the Administrative Agent shall advise the Borrower
before 10:00 A.M. (New York City time) on the proposed Borrowing Date of the
contents of each such Bid Loan Offer received by it. If the Administrative Agent
in its capacity as a Bank shall, in its sole discretion, elect to make any such
offer, it shall advise the Borrower of the contents of its Bid Loan Offer before
9:15 A.M. (New York City time) on the proposed Borrowing Date.

         (c) The Borrower shall before 10:30 A.M. (New York City time) on the
proposed Borrowing Date, in its absolute discretion, either:

               (i)cancel such Bid Loan Request by giving the Administrative
         Agent telephone notice to that effect, and the Administrative Agent
         shall give prompt telephone notice thereof to the Banks and the Bid
         Loans requested thereby shall not be made; or

               (ii)accept one or more of the offers made by any Bank or Banks by
         giving telephone notice to the Administrative Agent (confirmed as soon
         as practicable thereafter by delivery to the Administrative Agent of a
         Bid


<PAGE>
                                                                              20

         Loan Confirmation in writing or by facsimile transmission) of the
         amount of Bid Loans for each relevant maturity date to be made by each
         Bank (which amount for each such maturity date shall be equal to or
         less than the maximum amount for such maturity date specified in the
         Bid Loan Offer of such Bid Loan Bank, and for all maturity dates
         included in such Bid Loan Offer shall be equal to or less than the
         aggregate maximum amount specified in such Bid Loan Offer for all such
         maturity dates) and reject any remaining offers made by Banks;
         provided, however, that (x) the Borrower may not accept offers for Bid
         Loans for any maturity date in an aggregate principal amount in excess
         of the maximum principal amount requested in the related Bid Loan
         Request, (y) if the Borrower accepts any of such offers, it must accept
         offers strictly based upon pricing for such relevant maturity date and
         no other criteria whatsoever and (z) if two or more Banks submit offers
         for any maturity date at identical pricing and the Borrower accepts any
         of such offers but does not wish to (or by reason of the limitations
         set forth in subsection 4.1 or in clause (x) of this proviso, cannot)
         borrow the total amount offered by such Banks with such identical
         pricing, the Borrower shall accept offers from all of such Banks in
         amounts allocated among them pro rata according to the amounts offered
         by such Banks.

         (d) If the Borrower accepts pursuant to clause (c) (ii) above one or
more of the offers made by any Bid Loan Bank or Bid Loan Banks, the
Administrative Agent shall notify before 11:00 A.M. (New York City time) each
Bid Loan Bank which has made such an offer, of the aggregate amount of such Bid
Loans to be made on such Borrowing Date for each maturity date and of the
acceptance or rejection of any offers to make such Bid Loans made by such Bid
Loan Bank. Each Bid Loan Bank which is to make a Bid Loan shall, before 12:00
Noon (New York City time) on the Borrowing Date specified in the Bid Loan
Request applicable thereto, make available to the Administrative Agent at its
office set forth in subsection 13.2 the amount of Bid Loans to be made by such
Bid Loan Bank, in immediately available funds. The Administrative Agent will
make such funds available to the Borrower at or before 2:00 P.M. (New York City
time) on such date at the Administrative Agent's aforesaid address. As soon as
practicable after each Borrowing Date, the Administrative Agent shall notify
each Bank of the aggregate amount of Bid Loans advanced on such Borrowing Date
and the respective maturity dates thereof.

         4.3 Repayments. Each Borrower shall repay to the Administrative Agent
for the account of each Bid Loan Bank which has made a Bid Loan on the maturity
date of each Bid Loan (such maturity date being that specified by the Borrower
for repayment of such Bid Loan in the related Bid Loan Request) the then unpaid
principal amount of such Bid Loan. The Borrowers shall not have the right to
prepay any principal amount of any Bid Loan without the prior written consent of
the Bid Loan Bank which made such Bid Loan.

         4.4 Interest on Bid Loans. Each Borrower which shall have borrowed a
Bid Loan shall pay interest on the unpaid principal amount of such Bid Loan from
the Borrowing Date to



<PAGE>
                                                                             21


the stated maturity date thereof, at the rate of interest determined pursuant to
subsection 4.2 above (calculated on the basis of a 360 day year for actual days
elapsed), payable on the interest payment date or dates specified by such
Borrower for such Bid Loan in the related Bid Loan Request. If all or a portion
of the principal amount of any Bid Loan shall not be paid when due (whether at
the stated maturity, by acceleration or otherwise), such overdue principal
amount shall, without limiting any rights of any Bank under this Agreement, bear
interest from the date on which such payment was due at a rate per annum which
is 2% above the rate which would otherwise be applicable to such Bid Loan until
the scheduled maturity date with respect thereto, and for each day thereafter at
a rate per annum which is 2% above the Alternate Base Rate until paid in full
(as well after as before judgment).

         4.5 Obligations of Borrowers; Bid Loan Notes. (a) Each Borrower agrees
that each Bid Loan made by each Bid Loan Bank to such Borrower pursuant hereto
shall constitute the promise and obligation of such Borrower to pay to the
Administrative Agent, on behalf of such Bid Loan Bank, at the office of the
Administrative Agent specified in subsection 13.2, in lawful money of the United
States of America and in immediately available funds the aggregate unpaid
principal amount of each Bid Loan made by such Bid Loan Bank to such Borrower
pursuant to subsection 4.2, which amounts shall be due and payable (whether at
maturity or by acceleration) as set forth in the Bid Loan Request related to
such Bid Loan and in this Agreement.

         (b) Each Borrower agrees that each Bid Loan Bank and the Administrative
Agent are authorized to record (i) the date and amount of each Bid Loan made by
such Bid Loan Bank to such Borrower pursuant to subsection 4.2, and (ii) the
date and amount of each payment or prepayment of principal of each such Bid
Loan, in the books and records of such Bid Loan Bank or the Administrative
Agent, as the case may be, and in such manner as is reasonable and customary for
such Bank or the Administrative Agent, as the case may be, and a certificate of
an officer of such Bid Loan Bank or the Administrative Agent, as the case may
be, setting forth in reasonable detail the information so recorded, shall
constitute prima facie evidence of the accuracy of the information so recorded;
provided that the failure to make any such recording shall not in any way affect
the obligations of such Borrower hereunder.

         (c) Each Borrower agrees that, upon the request to the Administrative
Agent by any Bid Loan Bank at any time, the Bid Loans made by such Bid Loan Bank
to any Borrower shall be evidenced by a promissory note of such Borrower,
substantially in the form of Exhibit B with appropriate insertions (a "Bid Loan
Note"), payable to the order of such Bid Loan Bank and representing the
obligation of such Borrower to pay the unpaid principal amount of all Bid Loans
made by such Bid Loan Bank, with interest on the unpaid principal amount from
time to time outstanding of each Bid Loan evidenced thereby as prescribed in
subsection 4.4. Upon the request to the Administrative Agent by any such Bid
Loan Bank at any time, such Borrower shall execute and deliver to such Bid Loan
Bank a Bid Loan Note conforming to the requirements hereof and executed by a
duly authorized officer of such Borrower. Each Bid Loan Bank is hereby
authorized to record the date and amount of each Bid Loan made by such Bank, the
maturity date thereof, the date and amount of each payment of principal thereof
and the interest rate with respect thereto on the schedule annexed to and
constituting part of its Bid Loan Note,



<PAGE>
                                                                              22



and any such recordation shall constitute prima facie evidence of the accuracy
of the information so recorded; provided, however, that the failure to make any
such recordation shall not affect the obligations of such Borrower hereunder or
under any Bid Loan Note. Each Bid Loan Note shall be dated the Closing Date and
each Bid Loan evidenced thereby shall bear interest for the period from and
including the Borrowing Date thereof on the unpaid principal amount thereof from
time to time outstanding at the applicable rate per annum determined as provided
in, and such interest shall be payable as specified in, subsection 4.4.

         SECTION 5. LOAN FACILITY COMMON PROVISIONS

         5.1 Interest Rates and Payment Dates. (a) Each Eurodollar Loan shall
bear interest for each day during each Interest Period with respect thereto at a
rate per annum equal to the Applicable Margin plus the Eurodollar Rate
determined for such Interest Period.

         (b) Each ABR Loan shall bear interest at a fluctuating rate per annum
equal to the Alternate Base Rate.

         (c) Except as otherwise provided in subsection 4.4, if all or a portion
of (i) the principal amount of any Loan or (ii) any interest payable thereon
shall not be paid when due (whether at the stated maturity, by acceleration or
otherwise), such overdue amount shall bear interest at a rate per annum which is
(x) in the case of overdue principal, the rate that would otherwise be
applicable thereto pursuant to the foregoing provisions of this subsection plus
2% or (y) in the case of overdue interest, the rate described in paragraph (b)
of this subsection plus 2%, in each case from the date of such non-payment until
such amount is paid in full (as well after as before judgment).

         (d) Interest shall be payable in arrears on each Interest Payment Date,
provided that interest accruing pursuant to paragraph (c) of this subsection
shall be payable on demand.

         (e) Subject to the limitations set forth herein, each Borrower may use
the Loans by borrowing, prepaying and reborrowing the Loans, all in accordance
with the terms and conditions hereof.

         5.2 Facility Fee, etc. (a) The Company agrees to pay to the
Administrative Agent for the account of each Bank a facility fee for the period
from and including the date hereof to the Termination Date, computed at the rate
per annum determined as set forth in paragraph (b) of this subsection on the
average daily amount of the Commitment of such Bank during the period for which
payment is made, payable quarterly in arrears on the fifteenth day of each
March, June, September and December and on the Termination Date or such earlier
date as the Commitments shall terminate as provided herein, commencing on the
first of such dates to occur after the date hereof.

         (b) The rate per annum at which such facility fee under paragraph (a)
above shall be computed (the "Applicable Facility Fee Rate"), for any day on
which the long term senior



<PAGE>
                                                                              23


unenhanced, unsecured debt of the Company is rated by both S&P and Moody's,
shall be the rate per annum under the caption "Facility Fee Rate" (a "Facility
Fee Rate") set forth below opposite the S&P and Moody's ratings applicable to
such debt on such day (or, if such ratings are set opposite two different rates
under said caption, then the Applicable Facility Fee Rate shall be the lower of
said two Facility Fee Rates):

         Facility Fee
         Rate                S&P                        Moody's
         ----                ---                        -------

         0.2500%             BB or lower              Ba2 or lower

         0.2000%             BB+                      Ba1

         0.1750%             BBB-                     Baa3

         0.1500%             BBB or higher            Baa2 or higher

provided that if on any day the long term senior unenhanced, unsecured debt of
the Company is rated by only one of S&P or Moody's, such rate will be determined
based on the rating by such rating agency, and provided, further, that if on any
day the long term senior unenhanced, unsecured debt of the Company is rated by
neither S&P nor Moody's, the Applicable Facility Fee Rate will be determined
based on the rating of such debt by a Substitute Rating Agency and will be the
Facility Fee Rate set forth above opposite the S&P and Moody's ratings
comparable to the Substitute Rating Agency's rating of such debt on such date,
and provided, further, that if on any day the long term senior unenhanced,
unsecured debt of the Company is rated by none of S&P, Moody's or any Substitute
Rating Agency, the Company, the Administrative Agent and the Banks will
negotiate in good faith to determine an alternative basis for calculating such
rate consistent with the table set forth above and, if agreement on such
alternative basis is not reached with 30 days, such rate will be calculated on
an alternative basis determined by the Administrative Agent and the Banks in
their reasonable discretion consistent with the table above, and until such
alternative basis is determined such rate will be the rate last determined as
provided in the table above.

         (c) The Company agrees to pay to the Administrative Agent, for the
account of Administrative Agent, the Banks and the Book Manager, the fees in the
amounts and on the dates previously agreed to in writing by the Company, the
Administrative Agent, the Banks and the Book Manager.

         5.3 Termination or Reduction of Commitments; Change of Control Date.
(a) The Company shall have the right, upon not less than five Business Days'
notice to the Administrative Agent, to terminate the Commitments or, from time
to time, to reduce the amount of the Commitments, provided that no such
termination or reduction shall be permitted to the extent that, after giving
effect thereto and to any prepayments of Loans made on the effective date
thereof, the sum of the aggregate Loan Outstandings of all the Banks, plus the
Aggregate Outstanding Bilateral Option Loans would exceed the Commitments then
in effect. Any such



<PAGE>
                                                                              24


partial reduction shall be in an amount equal to $5,000,000 or a whole multiple
of $1,000,000 in excess thereof and shall reduce permanently the Commitments
then in effect.

         (b) (i) In the event that a Change of Control Date shall occur, (A) the
Company shall, within 10 days after such Change of Control Date, give each Bank
notice thereof in writing describing in reasonable detail the facts and
circumstances giving rise thereto, and (B) such Bank, by written notice given to
the Company not later than 30 days after the Change of Control Date, may declare
the Commitments of such Bank to be terminated in full or reduced as of the date
of (or as of a later date specified in) such notice to the Company, and may
require that the Borrowers prepay as provided in this subsection 5.3 any Loans
payable to such Bank and outstanding on such date to the extent the principal
amount thereof exceeds such Bank's Commitment, if any, remaining after such
termination or reduction. To the extent such Bank so requires, the Borrowers
shall prepay such Loans on the 75th day after the date of the Company's notice
or, in the event such 75th day is not a Business Day, the Business Day next
succeeding such 75th day ("Prepayment Date").



         (ii) On the Prepayment Date, the Borrowers shall prepay the unpaid
principal amount of the Loans payable to such Bank, without premium or penalty,
together with accrued interest on the amount prepaid to the Prepayment Date.

         (iii) Subsections 5.9(a), (b) and (c) shall not apply to prepayments
under this subsection 5.3(b).

         (iv)Paragraph (a) of this subsection 5.3 hereof shall not apply to any
Commitment reductions pursuant to this paragraph (b).

         (v)In the event that a Change of Control Date shall occur, the Company
shall not thereafter, without the prior written consent of the Majority Banks,
borrow any additional Loan (other than a Bilateral Option Loan) in order to
make, directly or indirectly, any payment or prepayment on any Indebtedness
subordinated as to the payment of principal and interest or on liquidation to
the prior payment of any of the Obligations.

         5.4 Prepayments. (a) Any Borrower may at any time and from time to time
upon at least four Business Days' irrevocable notice to the Administrative
Agent, in the case of Eurodollar Loans, or upon at least one Business Day's
irrevocable notice to the Administrative Agent, in the case of ABR Loans, prepay
the Loans (other than Bid Loans), in whole or in part, without premium or
penalty (subject to subsection 5.13), specifying the date and amount of
prepayment and whether the prepayment is of Eurodollar Loans, ABR Loans or a
combination thereof, and, if of a combination thereof, the amount allocable to
each. Upon receipt of any such notice the Administrative Agent shall promptly
notify each Bank thereof. If any such notice is given, the amount specified in
such notice shall be due and payable on the date specified therein. Partial
prepayments shall be in an aggregate principal amount of $5,000,000 or a whole
multiple of $1,000,000 in excess thereof.

                                                                              25


         (b) If at any time, the Administrative Agent shall determine (which
determination shall be conclusive in the absence of manifest error) that the sum
of the aggregate Loan Outstandings of all the Banks plus the Aggregate
Outstanding Bilateral Option Loans exceeds the aggregate Commitments, the
Borrowers shall immediately prepay the Loans in an aggregate principal amount
equal to such excess.

         5.5 Conversion and Continuation Options. (a) Any Borrower may elect at
any time and from time to time (subject to subsection 5.13) to convert its
Eurodollar Loans to ABR Loans by giving the Administrative Agent at least two
Business Days' prior irrevocable notice of such election. Any Borrower may elect
at any time and from time to time to convert its ABR Loans to Eurodollar Loans
by giving the Administrative Agent irrevocable notice of such election (which
notice must be received by the Administrative Agent prior to 4:00 P.M., New York
City time, three Business Days prior to the requested conversion date). Any such
notice of conversion to Eurodollar Loans shall specify the length of the initial
Interest Period or Interest Periods therefor. Upon receipt of any such notice
the Administrative Agent shall promptly notify each Bank thereof. All or any
part of outstanding Eurodollar Loans and ABR Loans may be converted as provided
herein, provided that (i) no Loan may be converted into a Eurodollar Loan when
any Event of Default has occurred and is continuing and the Administrative Agent
or the Majority Banks have determined that such a conversion is not appropriate,
and (ii) any such conversion may only be made if, after giving effect thereto,
subsection 5.6 shall not have been contravened.

         (b) Any Eurodollar Loans may be continued as such upon the expiration
of the then current Interest Period with respect thereto by the Borrower thereof
giving notice to the Administrative Agent, in accordance with the applicable
provisions of the term "Interest Period" set forth in subsection 1.1, of the
length of the next Interest Period to be applicable to such Loans, provided that
no Eurodollar Loan may be continued as such (i) when any Event of Default has
occurred and is continuing and the Administrative Agent or the Majority Banks
have determined that such a continuation is not appropriate, or (ii) if, after
giving effect thereto, subsection 5.6 would be contravened and provided,
further, that if any Borrower shall fail to give any required notice as
described above in this paragraph or if such continuation is not permitted
pursuant to the preceding proviso such Loans shall be automatically converted to
ABR Loans on the last day of such then expiring Interest Period.

         5.6 Minimum Amounts of Eurodollar Tranches. All borrowings, conversions
and continuations of Loans hereunder and all selections of Interest Periods
hereunder shall be in such amounts and be made pursuant to such elections so
that, after giving effect thereto, the aggregate principal amount of the Loans
comprising each Eurodollar Tranche shall be equal to $5,000,000 or a whole
multiple of $1,000,000 in excess thereof.

         5.7 Computation of Interest and Fees. (a) Interest on ABR Loans and
facility fees shall be calculated on the basis of a 365- (or 366-, as the case
may be) day year for the actual days elapsed. Interest on Eurodollar Loans shall
be calculated on the basis of a 360-day year for the actual days elapsed. The
Administrative Agent shall as soon as practicable notify the Borrowers and the
Banks of each determination of a Eurodollar Rate. Any change in the interest

                                                                              26


rate on a Loan resulting from a change in the Prime Rate shall become effective
as of the opening of business on the day on which such change in the Prime Rate
is announced. The Administrative Agent shall as soon as practicable notify the
Borrowers and the Banks of the effective date and the amount of each such change
in interest rate.

         (b) Each determination of an interest rate by the Administrative Agent
pursuant to any provision of this Agreement shall be conclusive and binding on
the Borrowers and the Banks in the absence of manifest error. The Administrative
Agent shall, at the request of the Company, deliver to the Company a statement
showing in reasonable detail the quotations and calculations used by the
Administrative Agent in determining any interest rate pursuant to subsections
5.1 and 5.7(a).

         5.8 Inability to Determine Interest Rate. In the event that prior to
the first day of any Interest Period:

               (a) the Administrative Agent shall have determined (which
         determination shall be conclusive and binding upon the Borrowers) that,
         by reason of circumstances affecting the relevant market, adequate and
         reasonable means do not exist for ascertaining the Eurodollar Rate for
         such Interest Period, or

               (b) the Administrative Agent shall have received notice from the
         Majority Banks that the Eurodollar Rate determined or to be determined
         for such Interest Period will not adequately and fairly reflect the
         cost to such Banks (as conclusively certified by such Banks) of making
         or maintaining their affected Loans during such Interest Period,

the Administrative Agent shall give telecopy or telephonic notice thereof to the
Borrowers and the Banks as soon as practicable thereafter. If such notice is
given (x) any Eurodollar Loans requested to be made on the first day of such
Interest Period shall be made as ABR Loans, (y) any Loans that were to have been
converted on the first day of such Interest Period to Eurodollar Loans shall be
continued as ABR Loans and (z) any outstanding Eurodollar Loans shall be
converted, on the first day of such Interest Period, to ABR Loans. Until such
notice has been withdrawn by the Administrative Agent, no further Eurodollar
Loans shall be made or continued as such, nor shall any Borrower have the right
to convert Loans to Eurodollar Loans.

         5.9 Pro Rata Treatment and Payments. (a) Each borrowing by any Borrower
of Revolving Credit Loans from the Banks hereunder, each payment by the Company
on account of any facility fee hereunder, and any reduction of the Commitments
of the Banks shall be made pro rata according to the respective Commitment
Percentages of the Banks.

         (b) Whenever any payment received by the Administrative Agent or any
Bank under this Agreement or any Note is insufficient to pay in full all amounts
then due and payable to the Administrative Agent and the Banks under this
Agreement and the Notes, and the Administrative Agent has not received a Payment
Sharing Notice (or if the Administrative Agent has received a Payment Sharing
Notice but the Event of Default specified in such Payment Sharing Notice has
been cured or waived), such payment shall be distributed and applied by the



<PAGE>
                                                                              27


Administrative Agent and the Banks in the following order: first, to the payment
of fees and expenses due and payable to the Administrative Agent in its capacity
as Administrative Agent under and in connection with this Agreement; second, to
the payment of all expenses due and payable under subsection 13.5, ratably among
the Banks in accordance with the aggregate amount of such payments owed to each
such Bank; third, to the payment of fees due and payable under subsections
5.2(a) and (b), ratably among the Banks in accordance with their Commitment
Percentages; fourth, to the payment of interest then due and payable on the
Loans, ratably among the Banks in accordance with the aggregate amount of
interest owed to each such Bank; and fifth, to the payment of the principal
amount of the Loans which is then due and payable, ratably among the Banks in
accordance with the aggregate principal amount owed to each such Bank.

         (c) After the Administrative Agent has received a Payment Sharing
Notice which remains in effect, all payments received by the Administrative
Agent under this Agreement or any Note shall be distributed and applied by the
Administrative Agent and the Banks in the following order: first, to the payment
of all amounts described in clauses first through third of the foregoing
paragraph (b), in the order set forth therein; and second, to the payment of the
interest accrued on and the principal amount of all of the Loans, regardless of
whether any such amount is then due and payable, ratably among the Banks in
accordance with the aggregate accrued interest plus the aggregate principal
amount owed to such Bank.

         (d) All payments (including prepayments) to be made by any Borrower
hereunder and under the Notes, whether on account of principal, interest, fees
or otherwise, shall be made without set-off or counterclaim and shall be made
prior to 3:00 P.M., New York City time, on the due date thereof (i) in the case
of fees and Loans other than Bilateral Option Loans, to the Administrative
Agent, for the account of the Banks, at the Administrative Agent's office
specified in subsection 13.2, and (ii) in the case of Bilateral Option Loans
made by any Bank, to such Bank, at the Bank's office specified in Schedule I
(or, with respect to Alternative Currency Bilateral Loans, if different, at such
other office of the Bank that it shall designate), in each case in Dollars (or,
with respect to Alternative Currency Bilateral Loans, in the relevant
Alternative Currency) and in immediately available funds. If any payment
hereunder becomes due and payable on a day other than a Business Day, such
payment shall be extended to the next succeeding Business Day (unless, with
respect to any payment on a Eurodollar Loan, the result of such extension would
be to extend such payment into another calendar month, in which event such
payment shall be made on the immediately preceding Business Day), and, with
respect to payments of principal, interest thereon shall be payable at the then
applicable rate during such extension.

         (e) Unless the Administrative Agent shall have been notified in writing
by the Bank prior to a Borrowing Date that such Bank will not make the amount of
any Loan it has committed to make on such date available to the Administrative
Agent, the Administrative Agent may assume that such Bank has made such amount
available to the Administrative Agent on such Borrowing Date, and the
Administrative Agent may, in reliance upon such assumption, make available to
the applicable Borrower a corresponding amount. If such amount is made available
to the Administrative Agent on a date after such Borrowing Date, such Bank shall
pay to the Administrative Agent on demand an amount equal to the product of (i)
the daily average Federal



<PAGE>

                                                                              28

Funds Effective Rate during such period, times (ii) the amount of the Loan such
Bank was committed to make, times (iii) a fraction the numerator of which is the
number of days that elapse from and including such Borrowing Date to the date on
which such Bank's Loan shall have become immediately available to the
Administrative Agent and the denominator of which is 360. A certificate of the
Administrative Agent submitted to any Bank with respect to any amounts owing
under this subsection shall be conclusive in the absence of manifest error. If
such Bank's Commitment Percentage of such borrowing is not in fact made
available to the Administrative Agent by such Bank within three Business Days of
such Borrowing Date, the Administrative Agent shall be entitled to recover such
amount with interest thereon at the rate per annum applicable to ABR Loans
hereunder, on demand, from such Borrower.

         5.10 Illegality. Notwithstanding any other provision herein, if any
change after the date hereof in any Requirement of Law or in the interpretation
or application thereof shall make it unlawful for any Bank to make or maintain
Eurodollar Loans as contemplated by this Agreement, (a) the commitment of such
Bank hereunder to make Eurodollar Loans, continue Eurodollar Loans as such and
convert ABR Loans to Eurodollar Loans shall forthwith be cancelled and (b) such
Bank's Loans then outstanding as Eurodollar Loans, if any, shall be converted
automatically to ABR Loans on the respective last days of the then current
Interest Periods with respect to such Loans or within such earlier period as
required by law. If any such conversion of a Eurodollar Loan occurs on a day
which is not the last day of the then current Interest Period with respect
thereto, the Borrower of such Loan shall pay to such Bank such amounts, if any,
as may be required pursuant to subsection 5.13.

         5.11 Requirements of Law. (a) In the event that any change after the
date hereof in any Requirement of Law or in the interpretation or application
thereof or compliance by any Bank with any request or directive (whether or not
having the force of law) from any central bank or other Governmental Authority
made subsequent to the date hereof:

               (i)shall subject any Bank to any tax of any kind whatsoever with
         respect to this Agreement, any Note or any Eurodollar Loan made by it,
         or change the basis of taxation of payments to such Bank in respect
         thereof (except for taxes covered by subsection 5.12 and changes in
         taxes based upon or measured by income of such Bank);

               (ii)shall impose, modify or hold applicable any reserve, special
         deposit, compulsory loan or similar requirement against assets held by,
         deposits or other liabilities in or for the account of, advances, loans
         or other extensions of credit by, or any other acquisition of funds by,
         any office of such Bank which is not otherwise included in the
         determination of the Eurodollar Rate hereunder; or

               (iii)shall impose on such Bank any other condition;

and the result of any of the foregoing is to increase the cost to such Bank, by
an amount which such Bank deems in its reasonable judgment to be material, of
making, converting into, continuing or maintaining Eurodollar Loans or to reduce
any amount receivable hereunder in respect thereof then, in any such case, the
Company shall promptly pay such Bank, upon its



<PAGE>
                                                                              29


demand, any additional amounts necessary to compensate such Bank for such
increased cost or reduced amount receivable. If any Bank becomes entitled to
claim any additional amounts pursuant to this subsection, it shall promptly
notify the Company, through the Administrative Agent, of the event by reason of
which it has become so entitled. A certificate as to any additional amounts
payable pursuant to this subsection setting forth the calculation thereof in
reasonable detail (as determined by such Bank in its reasonable discretion)
submitted by such Bank, through the Administrative Agent, to the Company shall
be conclusive in the absence of manifest error. This covenant shall survive the
termination of this Agreement and the payment of the Notes and all other amounts
payable hereunder.

         (b) In the event that any Bank shall have determined that any change in
any Requirement of Law regarding capital adequacy or in the interpretation or
application thereof or compliance by such Bank or any corporation controlling
such Bank with any request or directive regarding capital adequacy (whether or
not having the force of law) from any Governmental Authority made subsequent to
the date hereof does or shall have the effect of reducing the rate of return on
such Bank's or such corporation's capital as a consequence of its obligations
hereunder to a level below that which such Bank or such corporation could have
achieved but for such change or compliance (taking into consideration such
Bank's or such corporation's policies with respect to capital adequacy) by an
amount deemed by such Bank to be material, then from time to time, after
submission by such Bank to the Company (with a copy to the Administrative Agent)
of a written request therefor, the Company shall pay to such Bank such
additional amount or amounts as will compensate such Bank for such reduction. A
certificate as to any additional amount payable pursuant to this subsection
setting forth the calculation thereof in reasonable detail (as determined by
such Bank in its reasonable discretion) through the Administrative Agent, to the
Company shall be conclusive in the absence of manifest error.

         (c) Upon request by any Bank, through the Administrative Agent, from
time to time, the Borrowers shall pay the cost of all Eurocurrency Reserve
Requirements applicable to the Eurodollar Loans made by such Bank. If a Bank is
or becomes entitled to receive payments in respect of Eurocurrency Reserve
Requirements, pursuant to this subsection 5.11(c), it shall promptly notify the
Borrowers thereof through the Administrative Agent. A certificate as to the
amount of such Eurocurrency Reserve Requirements setting forth the calculation
thereof in reasonable detail (as determined by such Bank in its reasonable
discretion) submitted by such Bank, through the Administrative Agent, to the
Borrowers shall be conclusive in the absence of manifest error. This covenant
shall survive the termination of this Agreement and the payment of the Loans and
all other amounts payable hereunder.

         5.12 Taxes. (a) All payments made by any Borrower under this Agreement
and any Notes shall be made free and clear of, and without deduction or
withholding for or on account of, any present or future income, stamp or other
taxes, levies, imposts, duties, charges, fees, deductions or withholdings, now
or hereafter imposed, levied, collected, withheld or assessed by any
Governmental Authority, excluding, in the case of the Administrative Agent and
each Bank, net income taxes and franchise taxes (imposed in lieu of net income
taxes) that would not have been imposed on the Administrative Agent or such
Bank, as the case may be, in the absence of a present or former connection
between the jurisdiction of the government or taxing



<PAGE>
                                                                              30


authority imposing such tax and the Administrative Agent or such Bank (other
than a connection arising solely from the Administrative Agent or such Bank
having executed, delivered or performed its obligations or received a payment
under, or enforced, this Agreement or any Notes) or any political subdivision or
taxing authority thereof or therein (all such non-excluded taxes, levies,
imposts, duties, charges, fees, deductions and withholdings being hereinafter
called "Taxes"). If any Taxes are required to be withheld from any amounts
payable to the Administrative Agent or any Bank hereunder or under any Notes,
the amounts so payable to the Administrative Agent or such Bank shall be
increased to the extent necessary to yield to the Administrative Agent or such
Bank (after payment of all Taxes) interest or any such other amounts payable
hereunder at the rates or in the amounts specified in this Agreement and the
Notes. Whenever any Taxes are payable by any Borrower in respect of any payment
made hereunder, as promptly as possible thereafter any Borrower shall send to
the Administrative Agent for its own account or for the account of such Bank, as
the case may be, a certified copy of an original official receipt received by
such Borrower showing payment thereof. If such Borrower fails to pay any Taxes
when due to the appropriate taxing authority or fails to remit to the
Administrative Agent the required receipts or other required documentary
evidence, such Borrower shall indemnify the Administrative Agent and the Banks
for any incremental taxes, interest or penalties that may become payable by the
Administrative Agent or any Bank as a result of any such failure. The agreements
in this subsection shall survive the termination of this Agreement and the
payment of the Notes and all other amounts payable hereunder.

         (b) Each Bank that is not incorporated under the laws of the United
States of America or a state thereof agrees that it will deliver to the Company
and the Administrative Agent (i) two duly completed copies of United States
Internal Revenue Service Form 1001 or 4224 or successor applicable form, as the
case may be, and (ii) an Internal Revenue Service Form W-8 or W-9 or successor
applicable form. Each such Bank also agrees to deliver to the Company and the
Administrative Agent two further copies of the said Form 1001 or 4224 and Form
W-8 or W-9, or successor applicable forms or other manner of certification, as
the case may be, on or before the date that any such form expires or becomes
obsolete or after the occurrence of any event requiring a change in the most
recent form previously delivered by it to the Company, and such extensions or
renewals thereof as may reasonably be requested by the Company or the
Administrative Agent, unless in any such case an event (including, without
limitation, any change in treaty, law or regulation) has occurred prior to the
date on which any such delivery would otherwise be required which renders all
such forms inapplicable or which would prevent such Bank from duly completing
and delivering any such form with respect to it and such Bank so advises the
Company and the Administrative Agent. Such Bank shall certify (i) in the case of
a Form 1001 or 4224, that it is entitled to receive payments under this
Agreement without deduction or withholding of any United States federal income
taxes and (ii) in the case of a Form W-8 or W-9, that it is entitled to an
exemption from United States backup withholding tax.

         5.13 Indemnity. Each Borrower agrees to indemnify each Bank and to hold
each Bank harmless from any loss or expense which such Bank may sustain or incur
as a consequence of (a) default by any Borrower in payment when due of the
principal amount of or interest on any Eurodollar Loan, (b) default by any
Borrower in making a borrowing of, conversion into or



<PAGE>
                                                                             31


continuation of Eurodollar Loans after such Borrower has given a notice
requesting the same in accordance with the provisions of this Agreement, (c)
default by any Borrower in making any prepayment after such Borrower has given a
notice thereof in accordance with the provisions of this Agreement or (d) the
making of a payment or prepayment of Eurodollar Loans on a day which is not the
last day of an Interest Period with respect thereto, including, without
limitation, in each case, any such loss or expense arising from the reemployment
of funds obtained by it or from fees payable to terminate the deposits from
which such funds were obtained. This covenant shall survive the termination of
this Agreement and the payment of the Loans or Notes, if any, and all other
amounts payable hereunder.

         SECTION 6. REPRESENTATIONS AND WARRANTIES

         To induce the Banks to enter into this Agreement, each of the Company
and the Parent represents and warrants to the Administrative Agent and each Bank
that:

         6.1 Corporate Existence; Compliance with Law. Each Loan Party (a) is a
corporation duly organized, validly existing and in good standing under the laws
of its jurisdiction of incorporation, (b) is duly qualified and in good standing
in each jurisdiction wherein, in the opinion of the Company and the Parent, the
conduct of its business or the ownership of its properties requires such
qualification and (c) is in compliance with all Requirements of Law, except to
the extent that the failure to comply with paragraph (a), (b) or (c) of this
subsection would not, in the aggregate, reasonably be expected to have a
Material Adverse Effect.

         6.2 Corporate Power, Authorization; Enforceable Obligations. Each Loan
Party has the corporate power and authority to make, deliver and perform its
obligations under the Loan Documents to which it is or will be a party, and has
taken all necessary corporate action to authorize (i) in the case of the
Borrowers, the borrowings under this Agreement and any Notes to which it is or
will be a party on the terms and conditions hereof and thereof and (ii) the
execution, delivery and performance of this Agreement and the Loan Documents to
which it is or will be a party. This Agreement has been, and any Note and the
other Loan Documents to which it is or will be a party will be, duly executed
and delivered on behalf of each relevant Loan Party. This Agreement constitutes,
and each of the Notes, if any, and the other Loan Documents when executed and
delivered will constitute, a legal, valid and binding obligation of the Loan
Party thereto, enforceable against such Loan Party in accordance with its terms,
such enforceability subject to limitations under any applicable bankruptcy,
insolvency, moratorium or other laws affecting creditors' rights and by general
equitable principles (whether applied in a proceeding in equity or at law). No
consent of any other party (including stockholders of the Parent) and no
consent, license, approval or authorization of, or registration or declaration
with, any Governmental Authority is required to be obtained by any Loan Party in
connection with the execution, delivery, performance, validity or enforceability
of this Agreement and any Notes.



<PAGE>
                                                                              32


         6.3 No Legal Bar. The execution, delivery and performance of this
Agreement, the Notes and the other Loan Documents, the borrowings hereunder and
the use of the proceeds thereof, will not violate or contravene any material
provision of any Requirement of Law or material Contractual Obligation of the
Parent, the Company or any of its Subsidiaries and will not result in, or
require, the creation or imposition of any material Lien (other than Liens
permitted under subsection 9.2) on any of its or their respective properties or
revenues pursuant to any such Requirement of Law or Contractual Obligation.

         6.4 No Material Litigation. There is no legal action, administrative
proceeding or arbitration (whether or not purportedly on behalf of the Parent or
the Company or any of its Subsidiaries) presently pending, or to the knowledge
of the Parent or the Company threatened, against or affecting the Parent or the
Company or any of its Subsidiaries which would reasonably be expected to have a
Material Adverse Effect, except that the foregoing is subject to the fact that
the Parent and the Company cannot predict at this time the results and impact,
if any, of (i) those litigations described in Item 3 of the Parent's Annual
Report on 10-K referred to in subsection 6.6 to the extent that inability to
estimate or determine liability is stated in Item 3 and (ii) the governmental
investigation and related matters described in Note 3 to the Consolidated
Financial Statements referred to in Item 3.

         6.5 Ownership of Properties. Each of the Parent, the Company and each
of its Subsidiaries is the tenant under valid leases or has good title to
substantially all its properties and assets, real and personal (except defects
in title and other matters that would not reasonably be expected to have a
Material Adverse Effect), subject to no Lien except as permitted to exist under
subsection 9.2.

         6.6 Financial Condition. The consolidated balance sheet of the Parent
and its Subsidiaries as at December 31, 1998 and the related consolidated
statements of operations, shareholders' equity and of cash flows (together with
the related notes), included or incorporated in the Parent's Annual Report on
Form 10-K filed with the SEC for the fiscal year ended December 31, 1998,
present fairly in all material respects the financial position of the Parent and
its Subsidiaries as at such dates and the results of their operations and their
cash flows for the fiscal years then ended. All of such financial statements,
including the notes to such financial statements, have been prepared in
conformity with GAAP (subject, in the case of interim statements, to normal
year-end adjustments and to the fact that such financial statements may be
abbreviated and may omit footnotes or contain incomplete footnotes) consistently
applied throughout the periods involved except as stated therein.

         6.7 Disclosure of Contingent Liabilities. To the best of the knowledge
and belief of the Parent, neither the Parent nor any of its Subsidiaries has any
contingent obligation, liability for taxes, long-term leases, unusual forward or
other liabilities, which are material in amount in relation to the consolidated
financial condition of the Parent and its Subsidiaries taken as a whole and
which are not disclosed in the financial statements (including the related
notes) described in subsection 6.6 above.

                                                                              33

         6.8 ERISA. Each Plan that is intended to qualify under Section 401(a)
of the Code satisfies in all material respects the applicable requirements for
qualification under that Code Section. No Reportable Event has occurred and is
continuing with respect to any such Plan, and neither the Parent nor any of its
Subsidiaries has incurred any liability to the PBGC under Section 4062 of ERISA
with respect to any such Plan that would reasonably be expected to have a
Material Adverse Effect.

         6.9 Certain Federal Regulations. Neither the Company nor any of its
Subsidiaries is engaged in or will engage in the business of extending credit
for the purposes of "purchasing" or "carrying" any "margin stock" within the
respective meanings of each of the quoted terms under Regulation U of the Board,
and no part of the proceeds of any Loan will be used for any purpose which
violates, or which would be inconsistent with, the provisions of Regulation U or
X of the Board.

         6.10 No Default. Neither the Parent nor any of its Subsidiaries is in
default under or with respect to any of its Contractual Obligations in any
respect which would reasonably be expected to have a Material Adverse Effect. No
Default or Event of Default has occurred and is continuing.

         6.11 Taxes. (a) Each of the Parent and its Subsidiaries has filed or
caused to be filed all tax returns which, to the knowledge of the Parent, are
required to be filed and has paid all taxes shown to be due and payable on said

other taxes, fees or other charges imposed on it or any of its property by any
Governmental Authority (other than any the amount or validity of which are
currently being contested in good faith by appropriate proceedings and with
respect to which adequate reserves to the extent required in conformity with
GAAP, have been provided on the books of the Parent or its Subsidiaries, as the
case may be) except insofar as the failure to make such filings or payments
would not reasonably be expected to have a Material Adverse Effect; and (b) no
tax Lien (other than a Lien permitted under subsection 9.2(a)) has been filed,
and, to the knowledge of the Parent, no claim is being asserted, with respect to
any such tax, fee or other charge which would reasonably be expected to have a

Company or any of its Subsidiaries is an "investment company", or a company
"controlled" by an "investment company", within the meaning of the Investment

Borrower is subject to regulation under any Federal or State statute or
regulation which limits its ability to incur Indebtedness.

         6.13 Purpose of Loans. The proceeds of the Loans shall be used by the
Borrowers for general corporate purposes (which may include purchases by the
Parent of its capital stock).

         6.14 Environmental Matters. To the best of the knowledge of the Parent,

owned or operated by

                                                                              34

respects, of (i) the computer systems of the Parent and its Subsidiaries and
(ii) any material equipment of the Parent and its Subsidiaries containing
embedded microchips and the testing of all such systems and equipment, as so
reprogrammed, is expected to be completed by June 30, 1999. The aggregate cost
to the Parent and its Subsidiaries of such reprogramming and testing and of the
reasonably foreseeable consequences of year 2000 to the Parent and its
Subsidiaries (including, without limitation, reprogramming errors and the
failure of others' systems or equipment) is not expected to result in a Default
or a Material Adverse Effect.

    holders) to cause, with the giving of notice if required, such Indebtedness
    to become due prior to its stated maturity; or

         (f) (i) The Parent or any Principal Subsidiary (other than the Excluded
    Subsidiaries) shall commence any case, proceeding or other action (A) under

    for purposes of Title IV of ERISA, (v) the Company or any Commonly

Administrative Agent shall, by notice to the Company declare the Commitments of

and all other notices of any kind are hereby expressly waived.

         SECTION 11. THE ADMINISTRATIVE AGENT

         11.1 Appointment. Each Bank hereby irrevocably designates and appoints
Chase as the Administrative Agent of such Bank under this Agreement and the
other Loan Documents, and each such Bank irrevocably authorizes Chase, as the
Administrative Agent for such Bank, to take such action on its behalf under the
provisions of this Agreement and the other Loan Documents and to exercise such
powers and perform such duties as are expressly delegated to the Administrative
Agent by the terms of this Agreement and the other Loan Documents, together with
such other powers as are reasonably incidental thereto. Notwithstanding any
provision to the contrary elsewhere in this Agreement, the Administrative Agent
shall not have any duties or responsibilities, except those expressly set forth
herein, or any fiduciary relationship with any Bank, and no implied covenants,
functions, responsibilities, duties, obligations or liabilities shall be read
into this Agreement or any other Loan Document or otherwise exist against the
Administrative Agent.

         11.2 Delegation of Duties. The Administrative Agent may execute any of
its duties under this Agreement and the other Loan Documents by or through
agents or attorneys-in-fact and shall be entitled to advice of counsel
concerning all matters pertaining to such duties. The Administrative Agent shall
not be responsible for the negligence or misconduct of any agents or
attorneys-in-fact selected by it with reasonable care.

         11.3 Exculpatory Provisions. Neither the Administrative Agent nor any
of its officers, directors, employees, agents, attorneys-in-fact or Affiliates
shall be (i) liable for any action lawfully taken or omitted to be taken by it
or such Person under or in connection with this Agreement or any other Loan
Document (except for its or such Person's own gross negligence or willful
misconduct) or (ii) responsible in any manner to any of the Banks for any
recitals, statements, representations or warranties made by any Loan Party or
any officer thereof contained in this Agreement or any other Loan Document or in
any certificate, report, statement or other document referred to or provided for
in, or received by the Administrative Agent under or in connection with, this
Agreement or any other Loan Document or for the value, validity, effectiveness,
genuineness, enforceability or sufficiency of this Agreement or the Notes or any
other Loan Document or for any failure of any Loan Party to perform its
obligations hereunder or thereunder. The Administrative Agent shall not be under
any obligation to any Bank to ascertain or to inquire as to the observance or
performance of any of the agreements contained in, or



<PAGE>
                                                                              46


conditions of, this Agreement or any other Loan Document, or to inspect the
properties, books or records of any Loan Party.

         11.4 Reliance by Administrative Agent. The Administrative Agent shall
be entitled to rely, and shall be fully protected in relying, upon any note,
writing, resolution, notice, consent, certificate, affidavit, letter, cablegram,
telegram, telecopy, statement, order or other document or conversation believed
by it to be genuine and correct and to have been signed, sent or made by the
proper Person or Persons and upon advice and statements of legal counsel
(including, without limitation, counsel to the Company, the Parent or any other
Borrower), independent accountants and other experts selected by the
Administrative Agent. The Administrative Agent may deem and treat the payee of
any Note as the owner thereof for all purposes unless a written notice of
assignment, negotiation or transfer thereof shall have been filed with the
Administrative Agent. The Administrative Agent shall be fully justified in
failing or refusing to take any action under this Agreement or any other Loan
Document unless it shall first receive such advice or concurrence of the
Majority Banks as it deems appropriate or it shall first be indemnified to its
satisfaction by the Banks against any and all liability and expense which may be
incurred by it by reason of taking or continuing to take any such action. The
Administrative Agent shall in all cases be fully protected in acting, or in
refraining from acting, under this Agreement and the Notes and the other Loan
Documents in accordance with a request of the Majority Banks, and such request
and any action taken or failure to act pursuant thereto shall be binding upon
all the Banks and all future holders of the Notes.

         11.5 Notice of Default. The Administrative Agent shall not be deemed to
have knowledge or notice of the occurrence of any Default or Event of Default
hereunder unless the Administrative Agent has received notice from a Bank or any
Loan Party referring to this Agreement, describing such Default or Event of
Default and stating that such notice is a "notice of default". In the event that
the Administrative Agent receives such a notice, the Administrative Agent shall
give notice thereof to the Banks. The Administrative Agent shall take such
action with respect to such Default or Event of Default as shall be reasonably
directed by the Majority Banks; provided that unless and until the
Administrative Agent shall have received such directions, the Administrative
Agent may (but shall not be obligated to) take such action, or refrain from
taking such action, with respect to such Default or Event of Default as it shall
deem advisable in the best interests of the Banks.

         11.6 Non-Reliance on Administrative Agent and Other Banks. Each Bank
expressly acknowledges that neither the Administrative Agent nor any of its
officers, directors, employees, agents, attorneys-in-fact or Affiliates has made
any representations or warranties to it and that no act by the Administrative
Agent hereinafter taken, including any review of the affairs of the Loan
Parties, shall be deemed to constitute any representation or warranty by the
Administrative Agent to any Bank. Each Bank represents to the Administrative
Agent that it has, independently and without reliance upon the Administrative
Agent or any other Bank, and based on such documents and information as it has
deemed appropriate, made its own appraisal of and investigation into the
business, operations, property, financial and other condition and
creditworthiness of the Loan Parties and made its own decision to make its Loans
hereunder and enter into this Agreement. Each Bank also represents that it will,
independently and without


<PAGE>
                                                                              47


reliance upon the Administrative Agent or any other Bank, and based on such
documents and information as it shall deem appropriate at the time, continue to
make its own credit analysis, appraisals and decisions in taking or not taking
action under this Agreement and the other Loan Documents, and to make such
investigation as it deems necessary to inform itself as to the business,
operations, property, financial and other condition and creditworthiness of the
Loan Parties. Except for notices, reports and other documents expressly required
to be furnished to the Banks by the Administrative Agent hereunder, the
Administrative Agent shall not have any duty or responsibility to provide any
Bank with any credit or other information concerning the business, operations,
property, condition (financial or otherwise), prospects or creditworthiness of
the Loan Parties which may come into the possession of the Administrative Agent
or any of its officers, directors, employees, agents, attorneys-in-fact or
Affiliates.

         11.7 Indemnification. The Banks agree to indemnify the Administrative
Agent in its capacity as such (to the extent not reimbursed by the Loan Parties
and without limiting the obligation of the Parent, the Company and any other
Borrower to do so), ratably according to the respective amounts of their
Commitments as in effect on the date on which the claim for indemnity by the
Administrative Agent is sought, from and against any and all liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements of any kind whatsoever which may at any time
(including, without limitation, at any time following the payment of the Notes)
be imposed on, incurred by or asserted against the Administrative Agent in any
way relating to or arising out of this Agreement, any of the other Loan
Documents or any documents contemplated by or referred to herein or therein or
the transactions contemplated hereby or thereby or any action taken or omitted
by the Administrative Agent under or in connection with any of the foregoing;
provided that no Bank shall be liable for the payment of any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements resulting solely from the Administrative
Agent's gross negligence or willful misconduct. The agreements in this
subsection shall survive the payment of the Notes and all other amounts payable
hereunder.

         11.8 Administrative Agent in Its Individual Capacity. The
Administrative Agent and its Affiliates may make loans to, accept deposits from
and generally engage in any kind of business with the Parent, the Company or any
other Borrower as though the Administrative Agent were not the Administrative
Agent hereunder and under the other Loan Documents. With respect to its Loans
made or renewed by it and any Note issued to it, the Administrative Agent shall
have the same rights and powers under this Agreement and the other Loan
Documents as any Bank and may exercise the same as though it were not the
Administrative Agent, and the terms "Bank" and "Banks" shall include the
Administrative Agent in its individual capacity.

         11.9 Successor Administrative Agent. The Administrative Agent may
resign as Administrative Agent upon 10 days' notice to the Banks. If the
Administrative Agent shall resign as Administrative Agent under this Agreement
and the other Loan Documents, then the Majority Banks shall appoint from among
the Banks a successor agent for the Banks, which successor agent shall be
approved by the Company, whereupon such successor agent shall succeed to the
rights, powers and duties of the Administrative Agent, and the term
"Administrative Agent" shall mean such successor agent effective upon its
appointment, and the former Administrative Agent's



<PAGE>
                                                                              48


rights, powers and duties as Administrative Agent shall be terminated, without
any other or further act or deed on the part of such former Administrative Agent
or any of the parties to this Agreement or any holders of the Notes. After any
retiring Administrative Agent's resignation as Administrative Agent, the
provisions of this subsection shall inure to its benefit as to any actions taken
or omitted to be taken by it while it was Administrative Agent under this
Agreement and the other Loan Documents.

         11.10 Others. Neither the Documentation Agent nor the Book Manager
shall have any rights or obligations under this Agreement except, if applicable,
in their capacity as a Bank hereunder.

         SECTION 12. GUARANTEES

         12.1 Parent Guarantee. The Parent hereby unconditionally and
irrevocably guarantees to the Administrative Agent and the Banks the prompt and
complete payment and performance by each of the Borrowers when due (whether at
the stated maturity, by acceleration or otherwise) of the Obligations owing to
the Administrative Agent and the Banks by such Borrowers. This guarantee (the
"Parent Guarantee") shall remain in full force and effect until the Obligations
of each of the Borrowers are indefeasibly paid in full, notwithstanding that
from time to time prior thereto any Borrower may be free from any Obligations.
The Parent agrees that whenever, at any time, or from time to time, it shall
make any payment to the Administrative Agent or any Bank on account of its
liability under this Parent Guarantee, it will notify the Administrative Agent
and such Bank in writing that such payment is made under this Parent Guarantee
for such purpose. No payment or payments made by any Borrower or any other
Person or received or collected by the Administrative Agent or any Bank from any
Borrower or any other Person by virtue of any action or proceeding or any offset
or appropriation or application, at any time or from time to time, in reduction
of or in payment of the Obligations of such Borrower shall be deemed to modify,
reduce, release or otherwise affect the liability of the Parent under this
Parent Guarantee, which shall remain obligated under this Parent Guarantee,
notwithstanding any such payment or payments until the Obligations are paid in
full.

         12.2 Company Guarantee. The Company hereby unconditionally and
irrevocably guarantees to the Administrative Agent and the Banks, the prompt and
complete payment and performance by each of the other Borrowers when due
(whether at the stated maturity, by acceleration or otherwise) of the
Obligations owing to the Administrative Agent and the Banks by such Borrowers.
This guarantee (the "Company Guarantee") shall remain in full force and effect
until the Obligations of each such Borrower are indefeasibly paid in full,
notwithstanding that from time to time prior thereto any such Borrower may be
free from any Obligations. The Company agrees that whenever, at any time, or
from time to time, it shall make any payment to the Administrative Agent or any
Bank on account of its liability under this Company Guarantee, it will notify
the Administrative Agent and such Bank in writing that such payment is made
under this Company Guarantee for such purpose. No payment or payments made by
any such Borrower or any other Person or received or collected by the
Administrative Agent or any Bank from any such Borrower or any other Person by
virtue of any action or proceeding or any offset or



<PAGE>
                                                                              49


appropriation or application, at any time or from time to time, in reduction of
or in payment of the Obligations of such Borrowers shall be deemed to modify,
reduce, release or otherwise affect the liability of the Company under this
Company Guarantee, which shall remain obligated under this Company Guarantee,
notwithstanding any such payment or payments until the Obligations of such
Borrowers are paid in full.

         12.3 No Subrogation, Contribution, Reimbursement or Indemnity.
Notwithstanding anything to the contrary in the Parent Guarantee and the Company
Guarantee (together, the "Guarantees", each a "Guarantee"), the Parent and the
Company (together, the "Guaranteeing Parties," each a "Guaranteeing Party")
hereby irrevocably waives all rights which may have arisen in connection with
its Guarantee to be subrogated to any of the rights (whether contractual, under
the Bankruptcy Code, including Section 509 thereof, under common law or
otherwise) of the Administrative Agent or any Bank against the Company or any
other Borrowers (together, the "Guaranteed Parties", each a "Guaranteed Party")
for the payment of the Obligations. Each Guaranteeing Party hereby further
irrevocably waives all contractual, common law, statutory or other rights of
reimbursement, contribution, exoneration or indemnity (or any similar right)
from or against any Guaranteed Party or Parties or any other Person which may
have arisen in connection with its Guarantee. So long as the Obligations remain
outstanding, if any amount shall be paid by or on behalf of any Guaranteed Party
to the Guaranteeing Party on account of any of the rights waived in this
subsection, such amount shall be held by such Guaranteeing Party in trust,
segregated from other funds of such Guaranteeing Party, and shall, forthwith
upon receipt by such Guaranteeing Party, be turned over to the Administrative
Agent in the exact form received by such Guaranteeing Party (duly endorsed by
such Guaranteeing Party to the Administrative Agent, if required), to be applied
against the Obligations of such Guaranteed Party or Parties, whether matured or
unmatured, in such order as the Administrative Agent may determine. The
provisions of this subsection as they apply to each of the Guaranteeing Parties
shall survive the payment in full of the Obligations of its Guaranteed Party or
Parties.

         12.4 Amendments, etc., with respect to the Obligations. Each
Guaranteeing Party shall remain obligated under its Guarantee notwithstanding
that, without any reservation of rights against such Guaranteeing Party, and
without notice to or further assent by such Guaranteeing Party, any demand for
payment of any of the Obligations made by the Administrative Agent or any Bank
may be rescinded by the Administrative Agent or such Bank, and any of the
Obligations continued, and the Obligations, or the liability of any other party
upon or for any part thereof, or any collateral security or guarantee therefor
or right of offset with respect thereto, may, from time to time, in whole or in
part, be renewed, extended, amended, modified, accelerated, compromised, waived,
surrendered or released by the Administrative Agent or any Bank, and this
Agreement, the Notes and the other Loan Documents may be amended, modified,
supplemented or terminated, in whole or in part, as the Administrative Agent or
the Banks (or the Majority Banks, as the case may be) may deem advisable from
time to time in accordance with the provisions of subsection 13.1(a), and any
collateral security, guarantee or right of set-off at any time held by the
Administrative Agent or any Bank for the payment of the Obligations may be sold,
exchanged, waived, surrendered or released. Neither the Administrative Agent nor
any Bank shall have any obligation to protect, secure, perfect or insure any
Lien at any time held by it


<PAGE>
                                                                              50


as security for the Obligations or for the obligations of any Guaranteeing Party
under its Guarantee or any property subject thereto.

         12.5 Guarantee Absolute and Unconditional. Each Guaranteeing Party
waives any and all notice of the creation, renewal, extension or accrual of any
of the Obligations and notice of or proof of reliance by the Administrative
Agent or any Bank upon its Guarantee or acceptance of its Guarantee; the
Obligations, and any of them, shall conclusively be deemed to have been created,
contracted or incurred in reliance upon the Guarantees; and all dealings between
the Borrowers and the Parent, on the one hand, and the Administrative Agent and
the Banks, on the other, shall likewise be conclusively presumed to have been
had or consummated in reliance upon the Guarantees. Each Guaranteeing Party
waives diligence, presentment, protest, notice of intent to accelerate, notice
of acceleration, demand for payment and notice of default or nonpayment to or
upon any Guaranteed Party or such Guaranteeing Party with respect to the
Obligations. The Guarantees shall be construed as a continuing, absolute and
unconditional guarantee of payment without regard to (a) the validity or
enforceability of this Agreement, any Note, any other Loan Document, any of the
Obligations or any collateral security therefor or guarantee or right of set-off
with respect thereto at any time or from time to time held by the Administrative
Agent or any Bank, (b) any defense, offset or counterclaim (other than a defense
of payment or performance) which may at any time be available to or be asserted
by any of the Guaranteed Parties against the Administrative Agent or any Bank or
(c) any other circumstance whatsoever (with or without notice to or knowledge of
any of the Guaranteed Parties or such Guaranteeing Party) which constitutes, or
might be construed to constitute, an equitable or legal discharge of any of the
Guaranteed Parties for the Obligations of such Guaranteed Party, or of such
Guaranteeing Party under its Guarantee, in bankruptcy or in any other instance.
When the Administrative Agent is pursuing its rights and remedies hereunder
against any Guaranteeing Party, the Administrative Agent or any Bank may, but
shall be under no obligation to, pursue such rights and remedies as it may have
against its Guaranteed Party or any other Person or against any collateral
security or guarantee for the Obligations or any right of offset with respect
thereto, and any failure by the Administrative Agent or any Bank to pursue such
other rights or remedies or to collect any payments from such Guaranteed Party
or such other Person or to realize upon any such collateral security or
guarantee or to exercise such right of offset or any release of such Guaranteed
Party or such other Person or of any such collateral security, guarantee or
right of offset, shall not relieve such Guaranteeing Party of any liability
under its Guarantee, and shall not impair or affect the rights and remedies,
whether express, implied or available as a matter of law, of the Administrative
Agent and the Banks against such Guaranteeing Party.

         12.6 Reinstatement. Each Guarantee shall continue to be effective, or
be reinstated, as the case may be, if at any time payment, or any part thereof,
of any of the Obligations of any Guaranteed Party thereunder is rescinded or
must otherwise be restored or returned by the Administrative Agent or any Bank
upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of

though such payments had not been made.

         SECTION 13. MISCELLANEOUS

         13.1 Amendments and Waivers; Replacement of Banks. (a) Neither this
Agreement, any Note, any other Loan Document, nor any terms hereof or thereof
may be amended, supplemented or modified except in accordance with the
provisions of this subsection. With the written consent of the Majority Banks,
the Administrative Agent, the Parent and the Company may, from time to time,
enter into written amendments, supplements or modifications hereto and to the
Notes, if any, and the other Loan Documents for the purpose of adding any
provisions to this Agreement or the Notes, if any, or the other Loan Documents
or changing in any manner the rights of the Banks, the Parent or of the
Borrowers hereunder or thereunder or waiving, on such terms and conditions as
the Administrative Agent may specify in such instrument, any of the requirements
of this Agreement or the Notes, if any, or the other Loan Documents or any
Default or Event of Default and its consequences; provided, however, that no
such waiver and no such amendment, supplement or modification shall (i) reduce
the amount or extend the maturity of any Loan or Note or any installment
thereof, or reduce the rate or extend the time of payment of interest thereon,
or reduce any fee payable to any Bank hereunder, or change the amount of any
Bank's Commitment, in each case without the consent of the Bank affected
thereby, or (ii) amend, modify or waive any provision of this subsection or
reduce the percentage specified in the definition of Majority Banks, or consent
to the assignment or transfer by the Parent or any Borrower of any of its rights
and obligations under this Agreement and the other Loan Documents, or amend,
modify or waive any provision of Section 12, in each case without the written
consent of all the Banks, or (iii) amend, modify or waive any provision of
Section 11 without the written consent of the then Administrative Agent. Any
such waiver and any such amendment, supplement or modification shall apply
equally to each of the Banks and shall be binding upon the Parent, the
Borrowers, the Banks, the Administrative Agent, all future holders of the Notes,
if any, and all future obligees under the Loans. In the case of any waiver, the
Parent, the Borrowers, the Banks and the Administrative Agent shall be restored
to their former position and rights hereunder and under the outstanding Loans or
Notes, if any, and any other Loan Documents, and any Default or Event of Default
waived shall be deemed to be cured and not continuing; but no such waiver shall
extend to any subsequent or other Default or Event of Default, or impair any
right consequent thereon.

         (b) Notwithstanding anything to the contrary contained in subsection
13.1(a), so long as no Default or Event of Default has occurred and is
continuing the Borrowers and the Parent shall be permitted in their discretion
(but, if any Revolving Credit Loans are then outstanding, with the consent of
the Majority Banks (which consent shall not be unreasonably withheld)) to amend
this Agreement to replace one or more Banks without the consent of any

                                                                              52


Bank to be so replaced pursuant to this subsection 13.1(b) (a "Replaced Bank")
and to provide for (w) the termination of the Commitments of such Replaced Bank,
(x) the addition to this Agreement of one or more other banking institutions, or
an increase in the Commitments of one or more of the other Banks (with the
consent of such other Banks), so that the total Commitments after giving effect
to such amendment shall be in the same amount as the total Commitments
immediately before giving effect to such amendment, (y) if any Loans are
outstanding at the time of such amendment, the making of such additional Loans
by such new financial institutions or other Bank or Banks, as the case may be,
as may be necessary to repay in full the outstanding Loans of such Replaced Bank
together with interest thereon and all accrued fees and indemnities with respect
thereto immediately before giving effect to such amendment and (z) such other
modifications to this Agreement as may be necessary to effect the replacement of
such Replaced Bank.

         (c) Notwithstanding anything to the contrary contained in paragraph (a)
or (b) of this subsection 13.1, if as a result of a change in any Requirement of
Law after the date hereof any Borrower or the Parent has become obligated to, or
reasonably believes that it will become obligated to pay to any Bank any
increased amount pursuant to subsection 5.11, 5.12 or 5.13, and such Bank shall
not have waived payment of such increased amounts, then the Borrowers and the
Parent may, if no Default or Event of Default has occurred and is continuing and
payment of any such increased amounts as have become due has been made or
appropriately provided for, upon five Business Days' notice to the
Administrative Agent and such Bank, amend this Agreement, without the consent of
any Bank or the Administrative Agent, to replace any one or more of the Banks to
which such increased amounts have become payable or would become payable and to
provide for the matters referred to in clauses (w), (x), (y) and (z) of
subsection 13.1(b), and such replaced Bank or Banks shall be deemed to be
Replaced Banks for purposes of such clauses.

delay in exercising, on the part of the Administrative Agent or any Bank, any

or modification to, this Agreement and any Notes and the other Loan Documents
and any other documents prepared in connection herewith or therewith, and the
consummation and administration of the transactions contemplated hereby and
thereby, including, without limitation, the fees and disbursements of counsel to
the Administrative Agent, (b) to pay or reimburse each Bank and the

limitation, fees and disbursements of counsel to the Administrative Agent and to

consummation or administration of any of the transactions contemplated by, or
any amendment, supplement or modification of, or any waiver or consent under or
in respect of, this Agreement, any Notes, the other Loan Documents and any such

foregoing, collectively, the "indemnified liabilities"), provided, that the
Company shall have no obligation hereunder to the Administrative Agent or any
Bank with respect to indemnified liabilities arising from (i) the gross
negligence or willful misconduct of the Administrative Agent or any such Bank,
(ii) legal proceedings commenced against the Administrative Agent or any such
Bank by any security holder or creditor thereof arising out of and based upon
rights afforded any such security holder or creditor solely in its capacity as
such, or (iii) legal proceedings commenced against the Administrative Agent or
any such Bank by any other Bank or by any Transferee (as defined in subsection
13.6). The agreements in this subsection shall survive repayment of the Loans or
Notes, if any, and all other amounts payable hereunder.

         13.6 Successors and Assigns; Participations; Purchasing Banks.

         (a) This Agreement shall be binding upon and inure to the benefit of
the Parent, the Borrowers, the Banks, the Administrative Agent, all future
holders of the Notes, if any, all future obligees under the Loans and their
respective successors and assigns, except that neither the Parent nor any
Borrower may assign or transfer any of its rights or obligations under this
Agreement without the prior written consent of each Bank.

         (b) Any Bank may, in the ordinary course of its commercial banking
business and in accordance with applicable law, at any time sell to one or more
banks or other entities ("Participants") participating interests in any Loan
owing to such Bank, any Note held by such Bank, any Commitments of such Bank or
any other interest of such Bank hereunder and under the other Loan Documents. In
the event of any such sale by a Bank of participating interests to a
Participant, such Bank's obligations under this Agreement to the other parties
to this Agreement



<PAGE>
                                                                              55


shall remain unchanged, such Bank shall remain solely responsible for the
performance thereof, such Bank shall remain the holder of any such Note, if any,
and the obligee under any such Loan for all purposes under this Agreement and
the other Loan Documents, and the Parent, the Borrowers and the Administrative
Agent shall continue to deal solely and directly with such Bank in connection
with such Bank's rights and obligations under this Agreement and the other Loan
Documents. The Parent and each of the Borrowers agrees that if amounts
outstanding under this Agreement and the Loans or the Notes, if any, are due or
unpaid, or shall have been declared or shall have become due and payable upon
the occurrence of an Event of Default, each Participant shall be deemed to have
the right of set-off in respect of its participating interest in amounts owing
under this Agreement and any Loan or Note to the same extent as if the amount of
its participating interest were owing directly to it as a Bank under this
Agreement or any Loan or Note, provided that such Participant shall only be
entitled to such right of set-off if it shall have agreed in the agreement
pursuant to which it shall have acquired its participating interest to share
with the Banks the proceeds thereof as provided in subsection 13.7. The Parent
and each of the Borrowers also agrees that each Participant shall be entitled to
the benefits of subsections 5.11, 5.12, 5.13 and 13.5 with respect to its
participation in the Commitments and the Loans outstanding from time to time;
provided, that no Participant shall be entitled to receive any greater amount
pursuant to such subsections than the transferor Bank would have been entitled
to receive in respect of the amount of the participation transferred by such
transferor Bank to such Participant had no such transfer occurred.

         (c) Any Bank may, in the ordinary course of its commercial banking
business and in accordance with applicable law, at any time sell to any Bank or
any affiliate thereof and, with the consent of the Company and upon notice to
the Administrative Agent, to one or more additional banks or financial
institutions ("Purchasing Banks") all or any part of its rights and obligations
under this Agreement and the Loans or the Notes, if any, pursuant to a
Commitment Transfer Supplement, substantially in the form of Exhibit H, executed
by such Purchasing Bank, such transferor Bank (and, in the case of a Purchasing
Bank that is not then a Bank or an affiliate thereof, by the Company and the
Administrative Agent) and delivered to the Administrative Agent for its
acceptance and recording in the Register. Upon such execution, delivery,
acceptance and recording, from and after the Transfer Effective Date determined
pursuant to such Commitment Transfer Supplement, (x) the Purchasing Bank
thereunder shall be a party hereto and, to the extent provided in such
Commitment Transfer Supplement, have the rights and obligations of a Bank
hereunder with a Commitment as set forth therein, and (y) the transferor Bank
thereunder shall, to the extent provided in such Commitment Transfer Supplement,
be released from its obligations under this Agreement (and, in the case of a
Commitment Transfer Supplement covering all or the remaining portion of a
transferor Bank's rights and obligations under this Agreement, such transferor
Bank shall cease to be a party hereto). Such Commitment Transfer Supplement
shall be deemed to amend this Agreement to the extent, and only to the extent,
necessary to reflect the addition of such Purchasing Bank and the resulting
adjustment of Commitment Percentages arising from the purchase by such
Purchasing Bank of all or a portion of the rights and obligations of such
transferor Bank under this Agreement and the Loan or the Notes, if any. On or
prior to the Transfer Effective Date determined pursuant to such Commitment
Transfer Supplement, the relevant Borrower, at its own expense, if the
Purchasing Bank so requests, shall execute and deliver to the Administrative
Agent in exchange for any


<PAGE>
                                                                              56


surrendered Revolving Credit Note and Bid Loan Note a new Revolving Credit Note
and Bid Loan Note to the order of such Purchasing Bank in an amount equal to the
Commitment assumed by it pursuant to such Commitment Transfer Supplement and, if
the transferor Bank has retained a Commitment hereunder, new Notes to the order
of the transferor Bank in an amount equal to the Commitment retained by it
hereunder. Such new Notes shall be dated the Closing Date and shall otherwise be
in the form of the Notes replaced thereby. Any Notes surrendered by the
transferor Bank shall be returned by the Administrative Agent to the Company
marked "cancelled".

         (d) The Administrative Agent shall maintain at its address referred to
in subsection 13.2 a copy of each Commitment Transfer Supplement delivered to it
and a register (the "Register") for the recordation of the names and addresses
of the Banks and the Commitment of, and principal amount of the Loans owing to,
each Bank from time to time. The entries in the Register shall be conclusive, in
the absence of manifest error, and the Parent, the Borrowers, the Administrative
Agent and the Banks may treat each Person whose name is recorded in the Register
as the owner of the Loan recorded therein for all purposes of this Agreement.
The Register shall be available for inspection by the Parent, the Borrowers or
any Bank at any reasonable time and from time to time upon reasonable prior
notice.

         (e) Upon its receipt of a Commitment Transfer Supplement executed by a
transferor Bank and Purchasing Bank (and, in the case of a Purchasing Bank that
is not then a Bank or an affiliate thereof, by the Company and the
Administrative Agent) together with payment to the Administrative Agent of a
registration and processing fee of $3,500, the Administrative Agent shall (i)
promptly accept such Commitment Transfer Supplement (ii) on the Transfer
Effective Date determined pursuant thereto record the information contained
therein in the Register and give notice of such acceptance and recordation to
the Banks and the Company.

         (f) The Parent and the Borrowers authorizes each Bank to disclose to
any Participant or Purchasing Bank (each, a "Transferee") and any prospective
Transferee any and all financial information in such Bank's possession
concerning such Borrower and its affiliates which has been delivered to such
Bank by or on behalf of the Parent, the Company or such Borrower pursuant to
this Agreement or which has been delivered to such Bank by or on behalf of the
Parent, the Company or such Borrower in connection with such Bank's credit
evaluation of such Borrower and its affiliates prior to becoming a party to this
Agreement.

         (g) If, pursuant to this subsection, any interest in this Agreement or
any Note is transferred to any Transferee which is organized under the laws of
any jurisdiction other than the United States or any state thereof, the
transferor Bank shall cause such Transferee, concurrently with the effectiveness
of such transfer, (i) to represent to the transferor Bank (for the benefit of
the transferor Bank, the Administrative Agent, the Parent and the Borrowers)
that under applicable law and treaties no taxes will be required to be withheld
by the Administrative Agent, the Parent, the Borrowers or the transferor Bank
with respect to any payments to be made to such Transferee in respect of the
Loans, (ii) to furnish to the transferor Bank (and, in the case of any
Purchasing Bank registered in the Register, the Administrative Agent, the Parent
and the



<PAGE>
                                                                              57


Company) either U.S. Internal Revenue Service Form 4224 or U.S. Internal Revenue
Service Form 1001 (wherein such Transferee claims entitlement to complete
exemption from U.S. federal withholding tax on all interest payments hereunder)
and (iii) to agree (for the benefit of the transferor Bank, the Administrative
Agent, the Parent and the Company) to provide the transferor Bank (and, in the
case of any Purchasing Bank registered in the Register, the Administrative
Agent, the Parent and the Company) a new Form 4224 or Form 1001 upon the
expiration or obsolescence of any previously delivered form and comparable
statements in accordance with applicable U.S. laws and regulations and
amendments duly executed and completed by such Transferee, and to comply from
time to time with all applicable U.S. laws and regulations with regard to such
withholding tax exemption.

         (h) Nothing herein shall prohibit any Bank from pledging or assigning
any Note to any Federal Reserve Bank in accordance with applicable law.

         13.7 Adjustments; Set-off.

         (a) If any Bank (a "benefitted Bank") shall at any time receive any
payment of all or part of its Revolving Credit Loans, or interest thereon, or
receive any collateral in respect thereof (whether voluntarily or involuntarily,
by set-off, pursuant to events or proceedings of the nature referred to in
Section 10(f), or otherwise), in a greater proportion than any such payment to
or collateral received by any other Bank, if any, in respect of such other
Bank's Revolving Credit Loans, or interest thereon, such benefitted Bank shall
purchase for cash from the other Banks such portion of each such other Bank's
Loan, or shall provide such other Banks with the benefits of any such
collateral, or the proceeds thereof, as shall be necessary to cause such
benefitted Bank to share the excess payment or benefits of such collateral or
proceeds ratably with each of the Banks; provided, however, that if all or any
portion of such excess payment or benefits is thereafter recovered from such
benefitted Bank, such purchase shall be rescinded, and the purchase price and
benefits returned, to the extent of such recovery, but without interest. Each
Borrower agrees that each Bank so purchasing a portion of another Bank's Loan
may exercise all rights of payment (including, without limitation, rights of
set-off) with respect to such portion as fully as if such Bank were the direct
holder of such portion.

         (b) In addition to any rights and remedies of the Banks provided by
law, each Bank shall have the right, without prior notice to the Parent and the
Borrowers, any such notice being expressly waived by the Parent and the
Borrowers, to the extent permitted by applicable law, upon any amount not being
paid when due and payable by any Borrower hereunder or under the Notes (whether
at the stated maturity, by acceleration or otherwise) to set-off and appropriate
and apply against such amount any and all deposits (general or special, time or
demand, provisional or final), in any currency, and any other credits,
indebtedness or claims, in any currency, in each case whether direct or
indirect, absolute or contingent, matured or unmatured, at any time held or
owing by such Bank or any branch or agency thereof to or for the credit or the
account of the Parent or such Borrower. Each Bank agrees promptly to notify the
Parent, the Borrowers and the Administrative Agent after any such set-off and
application made by such Bank, provided that the failure to give such notice
shall not affect the validity of such set-off and application.

                                                                              58


         13.8 Counterparts. This Agreement may be executed by one or more of the
parties to this Agreement on any number of separate counterparts, and all of
said counterparts taken together shall be deemed to constitute one and the same
instrument. A set of the copies of this Agreement signed by all the parties
shall be lodged with the Parent, the Company and the Administrative Agent.

         13.9 Severability. Any provision of this Agreement which is prohibited
or unenforceable in any jurisdiction shall, as to such jurisdiction, be
ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.

         13.10 Integration. This Agreement represents the agreement of the
Parent, each Borrower, the Administrative Agent and the Banks with respect to
the subject matter hereof, and there are no promises, undertakings,
representations or warranties by the Administrative Agent or any Bank relative
to subject matter hereof not expressly set forth or referred to herein, in the
other Loan Documents or in any documentation entered into pursuant to subsection
3.1(b).

         13.11 GOVERNING LAW. THIS AGREEMENT (INCLUDING SECTION 12) AND THE
NOTES AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES UNDER THIS AGREEMENT AND THE
NOTES SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH,
THE LAW OF THE STATE OF NEW YORK.

         13.12 Submission to Jurisdiction; Waivers. (a) The Parent, each
Borrower, the Administrative Agent and the Banks hereby irrevocably and
unconditionally:

                    (i) submits for itself and its property in any legal action
         or proceeding relating to this Agreement and the other Loan Documents
         to which it is a party, or for recognition and enforcement of any
         judgment in respect thereof, to the non-exclusive general jurisdiction
         of the Courts of the State of New York sitting in New York County, the
         courts of the United States of America for the Southern District of New
         York, and the appellate courts from any thereof;

                    (ii) consents that any such action or proceeding may be
         brought in such courts and waives any objection that it may now or
         hereafter have to the venue of any such action or proceeding in any
         such court or that such action or proceeding was brought in an
         inconvenient court and agrees not to plead or claim the same;

                    (iii) agrees that service of process in any such action or
         proceeding may be effected by mailing a copy thereof by registered or
         certified mail (or any substantially similar form of mail), postage
         prepaid, to the Parent or such Borrower at its address set forth in
         subsection 13.2 or, with respect to Borrowers other than the Company,

                    (iv) agrees that nothing herein shall affect the right to
         effect service of process in any other manner permitted by law or shall
         limit the right to sue in any other jurisdiction; and

                    (v) waives, to the maximum extent not prohibited by law, any
         right it may have to claim or recover in any legal action or proceeding
         referred to in this subsection any special, exemplary, punitive or
         consequential damages.

         (b) Each Borrower other than the Company hereby appoints and empowers
    the Parent and the Company, 1114 Avenue of the Americas, New York, New York
    10036-7794, Attention: Treasurer, as its authorized agent (the "Process
    Administrative Agent") to receive on behalf of such Borrower service of any
    and all process and documents in any such legal action or proceeding brought
    in a New York state or federal court sitting in New York City. It is
    understood that a copy of such process served on the Process Administrative
    Agent will be promptly hand delivered or mailed (by registered or certified
    airmail if available), postage prepaid, to such Borrower at its address set
    forth in paragraph 5 of such Borrower's Notice of Additional Borrower, but
    the failure of such Borrower to receive such copy shall not affect in any
    way the service of such process on the Process Administrative Agent. If the
    Process Administrative Agent shall refuse or be prevented from acting as
    agent, notice thereof shall immediately be given by such Borrowers to the
    Administrative Agent by registered or certified airmail (if available),
    postage prepaid, and such Borrowers agree promptly to designate another
    agent in New York City, satisfactory to the Administrative Agent, to serve
    in place of the Process Administrative Agent and deliver to the
    Administrative Agent written evidence of such substitute agent's acceptance
    of such designation.

         13.13 Acknowledgments. The Parent, each Borrower, the Administrative
Agent and the Banks hereby acknowledge that:

         (a) it has been advised by counsel in the negotiation, execution and
    delivery of this Agreement and the Notes and the other Loan Documents;

         (b) neither the Administrative Agent nor any Bank has any fiduciary
    relationship with or duty to the Parent or such Borrower, as the case may
    be, arising out of or in connection with this Agreement or any of the other
    Loan Documents, and the relationship between Administrative Agent and Banks,
    on one hand, and the Parent and the Borrowers, on the other hand, in
    connection herewith or therewith is solely that of debtor and creditor; and

         (c) as to any matter relating to any Loan Documents, no joint venture
    exists among the Banks or among the Parent, the Borrowers and the Banks.

         13.14 WAIVERS OF JURY TRIAL. THE PARENT, THE BORROWERS, THE
    ADMINISTRATIVE AGENT AND THE BANKS HEREBY IRREVOCABLY AND UNCONDITIONALLY
    WAIVE TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING RELATING TO THIS
    AGREEMENT OR THE NOTES OR ANY OTHER LOAN DOCUMENT AND FOR ANY COUNTERCLAIM
    THEREIN.

         13.15 Additional Borrowers. (a) Any Subsidiary of the Company shall
    have the right to become a "Borrower" hereunder, and to borrow hereunder
    subject to the terms and conditions hereof applicable to a Borrower and to
    the following additional conditions:

                    (i) the Company shall deliver a notice in substantially the
     form of Exhibit I hereto (a "Notice of Additional Borrower") signed by such
     Subsidiary and countersigned by the Parent and the Company to the
     Administrative Agent and the Banks stating that such Subsidiary desires to
     become a "Borrower" under this Agreement and agrees to be bound by the
     terms hereof. From the time of receipt of such Notice of Additional
     Borrower by the Administrative Agent and the Banks and subject to the
     satisfaction of each condition precedent contained in such Notice of
     Additional Borrower, such Subsidiary shall be a "Borrower" hereunder with
     all of the rights and obligations of a Borrower hereunder; provided,
     however, that the Company may revoke a Notice of Additional Borrower with
     respect to any Subsidiary (other than the Company) upon five Business Days'
     written notice to the Administrative Agent, so long as such Borrower has no
     Obligations outstanding. No Notice of Additional Borrower relating to a
     Subsidiary may be revoked as to amounts owed by such Subsidiary to the
     Banks under this Agreement or any Notes or when an irrevocable notice
     pursuant to subsection 2.3, or a notice of acceptance pursuant to
     subsection 3.1 or 4.2, has been given by such Subsidiary as a Borrower and
     is effective;

                    (ii) if such Subsidiary is a Foreign Subsidiary, if
     reasonably requested by the Majority Banks, such Notice of Additional
     Borrower shall be accompanied by an opinion of counsel for such Subsidiary
     as specified in paragraph 4(a)(ii) of such Notice of Additional Borrower;

                    (iii) and the other conditions set forth in such Notice of
     Additional Borrower shall have been satisfied (including the
     representations and warranties contained therein being true and correct as
     of the date thereof).

         (b) Promptly, upon receipt of any Notice of Additional Borrower by the
Administrative Agent, the Administrative Agent shall notify each Bank thereof,
and shall deliver to each Bank copies of each document delivered to the
Administrative Agent pursuant to such Notice of Additional Borrower.

Ladies and Gentlemen:

         As General Counsel of W. R. Grace & Co. (formerly named Grace Specialty
Chemicals, Inc.), a Delaware corporation (the "Parent"), and W. R. Grace &
Co.-Conn., a Connecticut corporation (the "Company"), I have been requested to

am rendering this opinion pursuant to subsection 7.1(c)(i) of the Credit

         I have examined or caused to be examined the Restated Certificate of
Incorporation and the By-laws of the Company, each as amended to date, the
Certificate of Incorporation and the By-laws of the Parent, each as amended to
date, the records of the meetings and other corporate proceedings of the Company
and of the Parent, the Credit Agreement, any Notes being delivered to you this

I deem necessary for the purposes of the opinion hereinafter expressed. For

         Based upon the foregoing, and subject to the qualifications stated
below, I am of the following opinion:

         1. The Company is a corporation duly organized and validly existing in
good standing under the laws of Connecticut, and has the corporate power and
authority under such laws, and is duly qualified and in good standing in each
jurisdiction in which, in the opinion of the Company, such qualification is
required, to own and operate its properties, to carry on its business and to
execute, deliver and perform its obligations under the Credit Agreement and the
Notes.

         2. The Parent is a corporation duly organized and validly existing in
good standing under the laws of Delaware and has the corporate power and
authority under such laws, and is duly qualified and in good standing in each
jurisdiction in which, in the opinion of the Parent, such qualification is
required, to own and operate its properties, to carry on its business and to
execute, deliver and perform its obligations under the Credit Agreement.

         3. The execution, delivery and performance by the Company of the Credit
Agreement and any Notes made by the Company, the borrowings by the Company
thereunder and the consummation of the other transactions contemplated thereby
have been duly and validly authorized by all necessary corporate action of the
Company.

         4. The execution, delivery and performance by the Parent of the Credit
Agreement and the consummation of the transactions contemplated thereby,
including, without limitation, the guaranty by the Parent of the Company's
Obligations, have been duly and validly authorized by all necessary corporate
action of the Parent.

         5. The Credit Agreement has been duly executed and delivered by duly
authorized officers of the Company and the Parent and each of the Notes, if any,
of the Company being delivered to you today has been duly executed and delivered
by a duly authorized officer of the Company.

         6. The Credit Agreement and any Notes made by the Company constitute,
and each other Note executed and delivered to you from time to time by the
Company hereafter will constitute, legal, valid and binding obligations of the
Company and the Parent, as the case may be, enforceable in accordance with their
respective terms.

         7. No consent of any other party (including, without limitation,
stockholders of the Company or of the Parent), and no authorization, license,
consent or approval from any regulatory, administrative or other governmental or
public body or authority, arbitrator or court of the United States or any state
or other jurisdiction thereof, is required in connection with the execution,
delivery and performance by the Company, and the Parent, as the case may be, or
the validity or enforceability, of the Credit Agreement or any Notes.

         8. The execution, delivery and the performance by the Company and the
Parent of the Credit Agreement and any Notes made by the Company, as the case
may be, will not (A) to

the best of my knowledge, violate any law or regulation applicable to the
Company or the Parent, (B) conflict with, or result in a breach or violation of,
the Restated Certificate of Incorporation or By-Laws, each as amended, of the
Company, the Certificate of Incorporation or By-laws, each as amended, of the
Parent or, to the best of my knowledge, any material indenture, loan agreement
or other agreement or instrument to which the Company or the Parent is a party
or under which the Company or the Parent or any of their respective properties
are or may be bound, or (C) to the best of my knowledge, violate any order,
award, judgment, determination, writ, injunction or decree applicable to the
Company or the Parent of any regulatory, administrative or other governmental or
public body or authority, arbitrator or court of the United States or any state
or other jurisdiction thereof.

         9. To the best of my knowledge, no litigation, proceeding,
investigation or inquiry is pending or threatened with respect to the
transactions contemplated by the Credit Agreement.

         10. Neither the Parent nor the Company is an "investment company", or a
company "controlled" by an "investment company", within the meaning of the
Investment Company Act of 1940, as amended.

         My opinion is subject to the following qualifications:

         (a) My opinion set forth in paragraph 6 above is subject to the effects
of bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and
other similar laws relating to or affecting creditors' rights generally, by
general equitable principles (whether considered in a proceeding in equity or at
law) and an implied covenant of good faith and fair dealing.

         (b) I express no opinion as to the enforceability of the provisions of
the Credit Agreement that purport to establish evidentiary standards or to make
determinations conclusive.

         (c) I express no opinion as to the enforceability of the provisions of
the Credit Agreement insofar as they relate to post-judgment interest rates.

         (d) I express no opinion as to the enforceability of subsection 3.3 of
the Credit Agreement. I note that (i) a New York statute provides that with
respect to a foreign currency obligation a New York State court shall render a
judgment or decree in such foreign currency and such judgment or decree shall be
converted into currency of the United States at the rate of exchange prevailing
on the date of entry of such judgment or decree and (ii) with respect to a
foreign currency obligation a federal court of the United States sitting in New
York may award judgment in U.S. dollars, provided that I express no opinion as
to the rate of exchange that such court would apply.

         (e) I express no opinion as to the validity, binding effect or
enforceability of any waiver under the Credit Agreement, or any consent or
authorization thereunder, relating to the rights of the Company or the Parent,
or duties owing to any of them, existing or arising as a matter of law.

         (f) I express no opinion as to the effect of any provision of the
Credit Agreement insofar as it provides that any Person purchasing a
participation from a Bank or other Person may exercise set-off or similar rights
with respect to such participation or that any Bank or other Person may exercise
set-off or similar rights other than in accordance with applicable law.

         (g) I express no opinion as to subsection 13.12 of the Credit Agreement
insofar as it relates to the waiver of any objection by the Company and the

District Court for the Southern District of New York (and note that such matters
may be raised by such court).

         (h) I express no opinion as to the effect of any provision of the
Credit Agreement which is intended to permit modification thereof only by means
of an agreement in writing by the parties thereto.

         (i) I express no opinion as to the effect of any provision of the
Credit Agreement imposing penalties or forfeitures.

         (j) I express no opinion as to the enforceability of any provision of
the Credit Agreement to the extent that such provision constitutes a waiver of
illegality as a defense to performance of contract obligations.

         (k) I express no opinion as to the effect of any provision of the
Credit Agreement relating to indemnification or exculpation in connection with
violations of any securities laws or relating to indemnification, contribution
or exculpation in connection with willful, reckless or criminal acts or gross
negligence of the indemnified or exculpated Person or the Person receiving
contribution.

         (l) I express no opinion as to any laws other than those of the states
of Connecticut, Delaware and New York and the federal laws of the United States.

         (m) As used in paragraph 1 above, the term "good standing" means only
those matters evidenced by the issuance of a certificate of existence pursuant
to Section 33.615(b) of the Connecticut Business Corporation Act, the absence of
any steps taken by the Company toward its dissolution and the filing by the
Company of all business and capital tax returns required to be filed, and the
payment of all taxes shown as payable on such returns that have become due, as
of the date hereof.

         This opinion is limited to the specific issues addressed herein and is
limited in all respects to laws and interpretations thereof and other matters
existing on the date hereof. I do not undertake to update this opinion for
changes in such laws, interpretations or matters. This opinion is furnished

                  FORM OF OPINION OF SIMPSON THACHER & BARTLETT

                                                                     May 5, 1999

To the banks listed on Schedule I hereto

Ladies and Gentlemen:

         We have acted as special New York counsel to The Chase Manhattan Bank,
as administrative agent, in connection with the preparation, execution and
delivery of the 364-Day Credit Agreement, dated as of May 5, 1999 (the "Credit
Agreement"), among W. R. Grace & Co.-Conn., W. R. Grace & Co. (formerly named
Grace Specialty Chemicals, Inc.), the banks from time to time party thereto,
Bank of America National Trust and Savings Association, as documentation agent,
The Chase Manhattan Bank, as administrative agent for said banks and Chase
Securities Inc., as book manager.

         This opinion is delivered to you pursuant to Section 7.1(c)(iii) of the
Credit Agreement. Terms used herein which are defined in the Credit Agreement
shall have the respective meanings set forth in the Credit Agreement, unless
otherwise defined herein.

         We have examined the following documents:

         (1) a copy of the Credit Agreement; and

         (2) a copy of the opinion of the General Counsel of the Company and the
Parent, addressed to you and dated the date hereof, in respect of the Credit
Agreement.

         In such examination we have assumed the genuineness of all signatures,
the legal capacity of natural persons, the authenticity of all documents
submitted to us as originals, the conformity to original documents of all
documents submitted to us as certified or photostatic copies, and the
authenticity of the originals of such latter documents.

         In rendering the opinion set forth below we have assumed that (2) the
Credit Agreement is a valid and legally binding obligation of each of the Banks
parties thereto, (3)(a) each of the Loan Parties is validly existing and in good
standing under the laws of the jurisdiction in which it is organized and has
duly authorized, executed and delivered the Credit Agreement in accordance with
its organizational documents, (b) execution, delivery and performance by each
Loan Party of the Credit Agreement do not violate the laws of the jurisdiction
in which it is organized or any other applicable laws (excepting the laws of the
State of New York and the Federal laws of the United States) and (c) execution,
delivery and performance by each Loan Party of the Credit Agreement do not
constitute a breach or violation of any agreement or instrument which is binding
upon such Loan Party and (4) no Loan Party is an "investment

company" within the meaning of and subject to regulation under the Investment
Company Act of 1940.

         To the extent that our opinion expressed below relates to matters not
expressly covered hereby that are set forth in the above-mentioned opinion of
the General Counsel of the Company and the Parent, we have assumed without
independent investigation the correctness of the matters set forth in such
opinion, our opinion being subject to the assumptions, qualifications and
limitations set forth in such opinion with respect thereto.

         Based upon the foregoing, and subject to the qualifications and
limitations stated herein, we hereby advise you that in our opinion, the Credit
Agreement constitutes a valid and legally binding obligation of each of the
Company and the Parent, enforceable against each of them in accordance with its
terms.

         Our opinion is subject to the following qualifications:

         (a) Our opinion set forth above is subject to the effects of
bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and
other similar laws relating to or affecting creditors' rights generally, general
equitable principles (whether considered in a proceeding in equity or at law),
and an implied covenant of good faith and fair dealing.

         (b) We express no opinion as to the enforceability of the provisions of
the Credit Agreement that purport to establish evidentiary standards or to make
determinations conclusive.

         (c) We express no opinion as to the enforceability of the provisions of
the Credit Agreement insofar as they relate to post-judgment interest rates.

         (d) We express no opinion as to the enforceability of subsection 3.3 of
the Credit Agreement. We note that (i) a New York statute provides that with
respect to a foreign currency obligation a New York State court shall render a
judgment or decree in such foreign currency and such judgment or decree shall be
converted into currency of the United States at the rate of exchange prevailing
on the date of entry of such judgment or decree and (ii) with respect to a
foreign currency obligation a U.S. Federal court sitting in New York may award
judgment in U.S. dollars, provided that we express no opinion as to the rate of
exchange that such court would apply.

         (e) We express no opinion as to the validity, binding effect or
enforceability of any waiver under the Credit Agreement, or any consent or
authorization thereunder, relating to the rights of the Company or the Parent,
or duties owing to any of them, existing or arising as a matter of law.

         (f) We express no opinion as to the effect of any provision of the
Credit Agreement insofar as it provides that any Person purchasing a
participation from a Bank or other Person may exercise set-off or similar rights
with respect to such participation or that any Bank

or other Person may exercise set-off or similar rights other than in accordance
with applicable law.

         (g) We express no opinion as to subsection 13.12 of the Credit
Agreement insofar as it relates to the waiver of any objection by the Company
and the Parent, to the venue of any legal action or proceeding brought in a
United States District Court for the Southern District of New York (and note
that such matters may be raised by such court).

         (h) We express no opinion as to the effect of any provision of the
Credit Agreement which is intended to permit modification thereof only by means
of an agreement in writing by the parties thereto.

         (i) We express no opinion as to the effect of any provision of the
Credit Agreement imposing penalties or forfeitures.

         (j) We express no opinion as to the enforceability of any provision of
the Credit Agreement to the extent that such provision constitutes a waiver of
illegality as a defense to performance of contract obligations.

         (k) We express no opinion as to the effect of any provision of the
Credit Agreement relating to indemnification or exculpation in connection with
violations of any securities laws or relating to indemnification, contribution
or exculpation in connection with willful, reckless or criminal acts or gross
negligence of the indemnified or exculpated Person or the Person receiving
contribution.

         In connection with the provisions of the Credit Agreement whereby the
Loan Parties submit to the jurisdiction of the United States District Court for
the Southern District of New York, we note the limitations of 28 U.S.C. ss. 1332
on Federal court jurisdiction where diversity of citizenship is lacking, and we
also note that such submissions cannot supersede such court's discretion in
determining whether to transfer an action from one Federal court to another
under 28 U.S.C. ss. 1404(a).

         We are members of the Bar of the State of New York and we do not
express any opinion herein concerning any law other than the law of the State of
New York and the federal law of the United States.

         This opinion is rendered to you in connection with the above-described
transactions. This opinion may not be relied upon by you for any other purpose,
or relied upon by any other person, firm or corporation without our prior
written consent.

                                          Very truly yours,

         Subsidiary, and if reasonably requested by the Majority Banks, an
         opinion of counsel for such Subsidiary to the effect that neither the

                    FORM OF OPINION OF COUNSEL TO THE COMPANY
                                 AND THE PARENT

                                                           ___________,_________



To each Bank from time to time
   party to the 364-Day Credit Agreement
   dated as of May 14, 1998,
   among W. R. Grace & Co.-Conn.,
   W. R. Grace & Co., the other Borrowers
   from time to time party thereto,
   the Banks named therein,
   Bank of America National Trust and Savings Association,
   as Documentation Agent,
   The Chase Manhattan Bank, as Administrative Agent and
   Chase Securities Inc., as Book Manager

Ladies and Gentlemen:

         As General Counsel of W. R. Grace & Co. (formerly named Grace Specialty
Chemicals, Inc.), a Delaware corporation (the "Parent"), and W. R. Grace &
Co.-Conn., a Connecticut corporation ("Company"), I have been requested to
render my opinion in connection with the Notice of Additional Borrower dated ,
("Notice") relating to [NAME OF SUBSIDIARY] ("Subsidiary") delivered pursuant to
the 364-Day Credit Agreement dated as of May 5 1999 (as modified by the Notice
and as otherwise amended, supplemented or otherwise modified prior to the date
hereof, the "Credit Agreement"), among you, the Company, the other Borrowers
from time to time party thereto, the Parent, Bank of America National Trust and
Savings Association, as Documentation Agent, The Chase Manhattan Bank, as
Administrative Agent and Chase Securities Inc., as Book Manager. I am rendering
this opinion pursuant to subsection 13.15(a) of the Credit Agreement and
subsection 4(a)(i) of the Notice. All terms used in this opinion that are
defined in the Credit Agreement have the respective meanings assigned to them
therein.

         I have examined or caused to be examined the Restated Certificate of
Incorporation and the By-laws of the Company, each as amended to date, the
Certificate of Incorporation and the By-laws of the Parent, each as amended to
date, the records of the meetings and other corporate proceedings of the Company
and of the Parent, the Credit Agreement, the Notice, and such other corporate
records, agreements, certificates and documents as I deem necessary for the
purposes of the opinion hereinafter expressed. For purposes of this opinion I


<PAGE>
                                                                               2

have assumed that all Notes issued from time to time hereafter will be issued in
accordance with the terms of the Credit Agreement.

         Based upon the foregoing, and subject to the qualifications stated
below, I am of the following opinion:

         1. The Company is a corporation duly organized and validly existing in
good standing under the laws of Connecticut, and has the corporate power and
authority under such laws, and is duly qualified and in good standing in each
jurisdiction in which, in the opinion of the Company, such qualification is
required, to own and operate its properties, to carry on its business and to
perform its obligations under the Credit Agreement.

         2. The Parent is a corporation duly organized and validly existing in
good standing under the laws of Delaware and has the corporate power and
authority under such laws, and is duly qualified and in good standing in each
jurisdiction in which, in the opinion of the Parent, such qualification is
required, to own and operate its properties, to carry on its business and to
perform its obligations under the Credit Agreement.

         3. The performance by the Company of the Credit Agreement and the
consummation of the transactions contemplated thereby, including, without
limitation, the guaranty by the Company of the Subsidiary's Obligations, have
been duly and validly authorized by all necessary corporate action of the
Company.

         4. The performance by the Parent of the Credit Agreement and the
consummation of the transactions contemplated thereby, including, without
limitation, the guaranty by the Parent of the Company's and the Subsidiary's
respective Obligations, have been duly and validly authorized by all necessary
corporate action of the Parent.

         5. The Credit Agreement constitutes the legal, valid and binding
obligation of the Company and the Parent, as the case may be, enforceable in
accordance with its terms.

         6. No consent of any other party (including, without limitation,
stockholders of the Company or the Parent), and no authorization, license,
consent or approval from any regulatory, administrative or other governmental or
public body or authority, arbitrator or court of the United States or any state
or other jurisdiction thereof, is required in connection with the performance by
the Company and the Parent, as the case may be, or the validity or
enforceability, of the Credit Agreement or any Notes.

         7. The performance by the Company and the Parent, of the Credit
Agreement will not (A) to the best of my knowledge, violate any law or
regulation applicable to the Company or the Parent, (B) conflict with, or result
in a breach or violation of, the Restated Certificate of Incorporation or
By-Laws, each as amended, of the Company, the Certificate of Incorporation or
By-laws, each as amended, of the Parent or, to the best of my knowledge, any
material indenture, loan agreement or other agreement or instrument to which the
Company or the Parent is a party or under which the Company or the Parent or any
of their respective properties are or may be


<PAGE>


                                                                               3

bound, or (C) to the best of my knowledge, violate any order, award, judgment,
determination, writ, injunction or decree applicable to the Company or the
Parent of any regulatory, administrative or other governmental or public body or
authority, arbitrator or court of the United States or any state or other
jurisdiction thereof.

         8. To the best of my knowledge, no litigation, proceeding,
investigation or inquiry is pending or threatened with respect to the
transactions contemplated by the Credit Agreement.

         9. Neither the Parent nor the Company is an "investment company", or a
company "controlled" by an "investment company", within the meaning of the
Investment Company Act of 1940, as amended.

         My opinion is subject to the following qualifications:

         (a) My opinion set forth in paragraph 5 above is subject to the effects
of ankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and
other similar laws relating to or affecting creditors' rights generally, by
general equitable principles (whether considered in a proceeding in equity or at
law) and an implied covenant of good faith and fair dealing.

         (b) I express no opinion as to the enforceability of the provisions of
the Credit Agreement that purport to establish evidentiary standards or to make
determinations conclusive.

         (c) I express no opinion as to the enforceability of the provisions of
the Credit Agreement insofar as they relate to post-judgment interest rates.

         (d) I express no opinion as to the enforceability of subsection 3.3 of
the Credit Agreement. I note that (i) a New York statute provides that with
respect to a foreign currency obligation a New York State court shall render a
judgment or decree in such foreign currency and such judgment or decree shall be
converted into currency of the United States at the rate of exchange prevailing
on the date of entry of such judgment or decree and (ii) with respect to a
foreign currency obligation a federal court of the United States sitting in New
York may award judgment in U.S. dollars, provided that I express no opinion as
to the rate of exchange that such court would apply.

         (e) I express no opinion as to the validity, binding effect or
enforceability of any waiver under the Credit Agreement, or any consent or
authorization thereunder, relating to the rights of the Company or the Parent,
or duties owing to any of them, existing or arising as a matter of law.

         (f) I express no opinion as to the effect of any provision of the
Credit Agreement insofar as it provides that any Person purchasing a
participation from a Bank or other Person may exercise set-off or similar rights
with respect to such participation or that any Bank or other Person may exercise
set-off or similar rights other than in accordance with applicable law.

                                                                               4

         (g) I express no opinion as to subsection 13.12 of the Credit Agreement
insofar as it relates to the waiver of any objection by the Company and the
Parent, to the venue of any legal action or proceeding brought in a United
States District Court for the Southern District of New York (and note that such
matters may be raised by such court).

         (h) I express no opinion as to the effect of any provision of the
Credit Agreement which is intended to permit modification thereof only by means
of an agreement in writing by the parties thereto.

         (i) I express no opinion as to the effect of any provision of the
Credit Agreement imposing penalties or forfeitures.

         (j) I express no opinion as to the enforceability of any provision of
the Credit Agreement to the extent that such provision constitutes a waiver of
illegality as a defense to performance of contract obligations.

         (k) I express no opinion as to the effect of any provision of the
Credit Agreement relating to indemnification or exculpation in connection with
violations of any securities laws or relating to indemnification, contribution
or exculpation in connection with willful, reckless or criminal acts or gross
negligence of the indemnified or exculpated Person or the Person receiving
contribution.

         (l) I express no opinion as to any laws other than those of the states
of Connecticut, Delaware and New York and the federal laws of the United States.

         (m) As used in paragraph 1 above, the term "good standing" means only
those matters evidenced by the issuance of a certificate of existence pursuant
to Section 33.615(b) of the Connecticut Business Corporation Act, the absence of
any steps taken by the Company toward dissolution and the filing by the Company
of all business and capital tax returns required to be filed, and the payment of
all taxes shown as payable on such returns that have become due, as of the date
hereof.

         This opinion is limited to the specific issues addressed herein and is
limited in all respects to laws and interpretations thereof and other matters
existing on the date hereof. I do not undertake to update this opinion for
changes in such laws, interpretations or matters. This opinion is furnished
solely for your benefit in connection with the transactions contemplated by the
Credit Agreement and the Notice, is not to be relied upon for any other purpose
and may not be made available to any other person, firm or entity (other than a
Transferee or a prospective Transferee referred to in subsection 13.6(f) of the
Credit Agreement) without my express prior written consent, except as may be
required by law or in response to any judicial or regulatory requirement, order
or decree.

                                    Very truly yours,

May 6, 1999

Mr. Robert M. Tarola
8550 Leisure Hill Drive
Baltimore, MD 21208

Dear Bob,

This letter agreement specifies the terms of your employment with W. R. Grace &
Co. (the "Company") as Senior Vice President & Chief Financial Officer
(collectively, the "CFO"), which will be presented for approval to the Company's
Board of Directors (the "Board") and/or the Compensation Committee of the Board,
as applicable, on May 11, 1999. The Board is extremely pleased that you will be
joining the Company and believes you will make a valuable contribution to the
Company's future.

If you agree with the terms of this letter agreement, please sign where
indicated below and return one fully executed copy to me. An additional copy of
this letter is also enclosed for your records.

RESPONSIBILITIES

Your employment with the Company is subject to Board approval and will begin as
of May 11, 1999. Your title will be "Senior Vice President & Chief Financial
Officer" of the Company, and you will report to me.

Your principal obligations, duties and responsibilities will be those generally
inherent in the office and title of CFO. Your office will be located at the
Company's Headquarters in Columbia, Maryland.

TERM OF AGREEMENT

The term of your employment under this agreement will be for a period of three
and one half years, beginning on the date your employment with the Company
commences, May 11, 1999 and ending on November 10, 2002 (such period is referred
to in this agreement as your "Employment Term").

If your employment as CFO of the Company (or in another position acceptable to
you) continues after the Employment Term, and no other contrary arrangements
have been mutually agreed in writing between you and the Board, then the
arrangements described in this agreement will be discontinued and you will be an
employee of the Company "at will" subject to the same requirements as similarly
situated employees of the Company at that
<PAGE>


Robert M. Tarola                     5/3/99                              Page 2
- --------------------------------------------------------------------------------

time, except as provided under the following sections entitled "Severance Pay
Arrangement" and "Special Supplemental Retirement Payment Arrangement".

COMPENSATION

1.    Your initial annual base salary as CFO will be $350,000.00. Thereafter,
      your base salary will be subject to periodic reviews on the same basis and
      at the same intervals as are applicable to other senior officers of the
      Company.

      Your salary will cease to accrue immediately upon your termination of
      employment with the Company, whether you voluntarily cease performing
      services or otherwise. (Note, however, the provisions below under
      "Severance Pay Arrangement".)

2.    You will be eligible to participate in the Company's Annual Incentive
      Compensation Program. Cash awards under this Program are contingent upon
      individual performance, and will be determined by the financial results of
      the Company as a whole. As CFO, under the current provisions of the
      Program, you will be eligible for a targeted award of 45% of your annual
      base salary with a maximum available award of 200% of the target; however,
      your actual award for 1999 will be no less than $129,000. All annual
      incentive compensation awards are subject to approval by the Compensation
      Committee and the Board and will be contingent upon your remaining with
      the Company through the date of payment (except with respect to the
      special provision for the 1999 award described in this paragraph).
      However, the payment for 1999 described above will be made in March 2000
      (reduced, if applicable, on a prorated basis to exclude any duplicate
      payments that may be payable to you under your severance arrangement) even
      in the event your employment is terminated by the Company without "Cause"
      before the date of payment, including termination of employment without
      "Cause" following a change-in-control of the Company. You will not,
      however, be entitled to that payment if you voluntarily resign, or are
      terminated for "Cause", prior to March 2000.

3.    Management will recommend that you be granted a stock option on May 11,
      1999, covering 100,000 shares of Grace Common Stock at the "Fair Market
      Value" on such date, which will vest in three share installments of
      33,333, 33,333 and 33,334 on May 12, 2000, 2001 and 2002, respectively;
      provided, however, all such installments would vest immediately upon
      termination of employment by the Company without "Cause" including
      termination of employment without "Cause" following a change-in-control of
      the Company. The stock option will be granted under the Company's 1998
      Stock Incentive Plan, which will govern the terms of that option, except
      as otherwise provided by this letter agreement.

      You will be eligible to receive periodic stock option grants in the future
      at the same times as other senior officers, and covering a number of
      shares consistent with your position as a senior officer of the Company.

4.    Consistent with your election as an officer of the Company, the Board will
      be requested to authorize the Company to enter into an Executive Severance
      Agreement or a so-called "golden parachute" with you. In general, the
      terms of that agreement would provide for a severance payment of 3 times
      the sum of your annual base salary

<PAGE>

Robert M. Tarola                     5/3/99                              Page 3
- --------------------------------------------------------------------------------


      plus your targeted annual incentive compensation award, and certain other
      benefits, in the event your employment terminates under certain conditions
      following a change-in-control of the Company.

      The form and provisions of your Executive Severance Agreement will be the
      same as applicable to other elected officers of the Company. Please refer
      to the Executive Severance Agreement for definition of "change in
      control", "employment termination" and other particulars of this
      arrangement.

SEVERANCE PAY ARRANGEMENT

If your employment is terminated by the Company without "Cause" during your
Employment Term, you will be entitled to the severance payment described in the
next sentence. The severance payment will be 2 times a dollar amount equal to
145% of your annual base salary at the time your employment is terminated. The
severance payment may be made to you in installments, at the same time and in
the same manner as salary continuation payments, over a period of two years
beginning as of the date you are terminated. However, at your option, the entire
severance payment may be paid to you in a single lump-sum as soon as practical
after your termination (if approved by the Compensation Committee).

The definition of "terminated by the Company without cause" shall mean: (i)
termination for reasons other than death or total disability or cause, or (ii)
resignation by you due to a significant change in the nature or scope of your
authorities or duties from those embodied in the role of CFO, or (iii)
resignation by you in response to a reduction in total compensation from that
provided in this agreement, or (iv) resignation by you in response to an
adjudicated breach by the Company of any provision of this agreement.

On the date your Employment Term expires (i.e., November 10, 2002), this
severance pay arrangement will no longer be applicable to you, and your
continued employment with the Company will be as an employee "at will",
provided, however, you will, as of the day immediately after that date, become
entitled to a severance payment of 1 times a dollar amount equal to 145% of your
annual base salary, if you are terminated by the Company without "Cause", at any
time after November 10, 2002.

You will not, in any event, however, be entitled to the severance payment
described above if, at the time your employment terminates, your employment
terminates as the result of your death, or you are entitled to payments under
your Executive Severance Agreement described above, or to disability income
payments under the Grace "LTD Plan" and/or "ESP Plan" described below.

Also, if you receive a severance payment under this agreement, you will not be
entitled to any other severance pay from the Company.

SPECIAL SUPPLEMENTAL RETIREMENT PAYMENT ARRANGEMENT

Management will recommend that the Board approve a special retirement
arrangement to recognize, in part, your service with prior employers and to
provide you with meaningful mid-career accrual of retirement benefits. As
described below, the Company will provide you with additional years of credited
service, with a maximum of 10 additional years, in

<PAGE>


Robert M. Tarola                     5/3/99                              Page 4
- --------------------------------------------------------------------------------

determining your total retirement benefits from the Company. The benefit
associated with those additional years would be calculated as if that additional
benefit would be payable under the W. R. Grace & Co. Retirement Plan for
Salaried Employees and the Supplemental Executive Retirement Plan ("SERP")
formulas (as described in items 2 and 3 below).

Basically, the additional service would be credited to you as follows:

1.    You would be credited with a minimum of 5 years of credited service on
      your date of employment.

2.    Following your date of employment, you will be credited with an additional
      year of credited service under this supplemental arrangement for each year
      of credited service you earn under the Grace Salaried Retirement and
      Supplemental Executive Retirement Plans.

      For example, if you were employed for 2 years after your date of
      employment, your total retirement benefit (i.e., from the plans plus the
      supplemental arrangement) would be based on the minimum of 5 years of
      credited service since your accumulated service (i.e., service under the
      plans plus under the supplemental arrangement) would be less than the
      minimum. If you were employed for 4 years, you would receive a total
      retirement benefit based on 8 years of credited service since your
      credited service under the plans and the supplemental arrangement would
      exceed the minimum number (i.e., 5). After 6 years, your total retirement
      benefit would be based on 12 years of credited service; and if you were
      employed for 10 years, your total retirement benefit would be based on 20
      years of credited service.

3.    After 10 years of employment with the Company, credited service would
      accrue each year under the Grace Retirement and Supplemental Retirement
      Plans only, because you would already have been credited with the maximum
      number of additional years of credited service under the supplemental
      arrangement - 10. For example, after 11 years of service with the Company,
      your total retirement benefit would be based on 21 years of credited
      service.

The supplemental retirement payment would not be offset by any benefits payable
to you from any of your previous employers, and would be payable from the
general assets of the Company -- it would not be pre-funded in any manner.

This supplemental retirement arrangement would apply only if your employment
with the Company ceases on or after the date your Employment Term expires (i.e.,
November 10, 2002), or if you are terminated during that Term, without "Cause",
including termination without "Cause" following a change-in-control of the
Company. However, in any event, this arrangement would not be applicable if you
voluntary terminate your employment before your Employment Term expires, or if
you are terminated for "Cause" prior to the expiration of that Term. In the
event of your death while you are entitled to a supplemental benefit, that
benefit will be payable as governed by the terms of the Salaried Retirement Plan
and the Supplemental Retirement Plan.

For purposes of determining any supplemental retirement benefit that may be
payable to you, if you leave the Company after the expiration of your Employment
Term or you are terminated by the Company without "Cause", your "final average
compensation" will be

<PAGE>


Robert M. Tarola                     5/3/99                              Page 5
- --------------------------------------------------------------------------------

determined in accordance with the formula provided under the basic Salaried
Retirement Plan, i.e., your final average compensation would be determined by
the number of months you are employed if less than 60 months.

Note, if the Grace Salaried Retirement Plan is amended in a manner that affects
the calculation of benefits, while you are employed by the Company, then this
supplemental retirement payment may be adjusted in an equitable manner
consistent with such amendment. Any such adjustment will be determined by the
actuary for the Salaried Retirement Plan; but such adjustment may not in any
event decrease your supplemental retirement payment below an amount that would
be calculated based on your years of service and "final average compensation" as
of the day before the effective date of such amendment.

DEFINITION OF CAUSE

"Cause", for purposes of this agreement, means:

(i)   Commission by you of a criminal act (i.e., any act which, if successfully
      prosecuted by the appropriate authorities would constitute a crime under
      State or Federal law) or of significant misconduct, which has had or will
      have a direct material adverse effect upon the business affairs,
      properties, operations or results of operations or financial condition of
      Company,

(ii)  Refusal or failure of you to comply with the mandates of the Board, or
      failure by you to substantially perform your duties hereunder, other than
      such failure resulting from your total or partial incapacity due to
      physical or mental illness, which refusal or failure has not been cured
      within 30 days after notice has been given to you, or

(iii) Breach of any of the terms of this agreement by you, which breach has not
      been cured within 30 days after notice has been given to you.

OTHER BENEFIT PROGRAMS

As a senior officer of the Company, you will also be eligible to participate in
the following benefit plans and programs (subject to the actual provisions of
the plans and programs, and as amended from time to time):

1.    The Grace Deferred Compensation Program provides that you may elect to
      defer a portion of your base salary (from a minimum of $200 per month to a
      maximum of 25% of base salary) and all or a portion of your annual
      incentive compensation. Deferred amounts are credited with interest equal
      to the greater of (i) the prime rate plus 2 percentage points or (ii) 120%
      of the prime rate.

2.    The W. R. Grace & Co. Retirement Plan for Salaried Employees ("Grace
      Salaried Retirement Plan") is a "tax qualified" plan that provides a
      pension at retirement equal to 1.50% of final average compensation (as
      defined by the Plan, which includes annual base salary and annual
      incentive compensation in the sixty (60) consecutive highest-paid months
      during the last 180 months of employment), less 1.25% of the primary
      Social Security benefit, multiplied by years of credited service.
      Participation in
<PAGE>


Robert M. Tarola                     5/3/99                              Page 6
- --------------------------------------------------------------------------------

      this Plan is effective the beginning of the month following one (1) year
      of employment with credited service retroactive to the first of the month
      beginning on or following the date of hire. A participant becomes 100%
      vested upon the earlier of (1) reaching five years of service or (2)
      attaining age 55.

3.    The W. R. Grace & Co. Supplemental Executive Retirement Plan ("SERP") is
      an unfunded Company plan that supplements benefits under the Grace
      Salaried Retirement Plan. The SERP pays retirement benefits which would
      otherwise be paid under the terms of the Salaried Retirement Plan, but for
      limits and exclusions imposed by tax law. For example, pension benefits
      related to base salary or incentive compensation awards, which an
      executive elects to defer, will be paid under the provisions of the SERP
      (not the Grace Salaried Retirement Plan). The SERP also pays any pension
      benefits that an executive accrues in excess of the "tax qualified" plan
      limits (currently $130,000 per year) and compensation limit (currently
      $160,000 per year). Participation, vesting and payment options in the SERP
      follow the same rules as the Grace Salaried Retirement Plan.

4.    The W. R. Grace & Co. Salaried Employee Savings & Investment Plan ("S&I
      Plan"). At the beginning of the month following one (1) year of
      employment, the S&I Plan permits you to save a portion of your
      compensation up to a maximum permitted by law by contributing such amount
      to the Plan by payroll deduction. With respect to the first 6% you
      contribute, the Company will match $1 of Grace stock for each $2 you save.
      Your contributions are invested in one or more of seven funds at your
      option. Grace's S&I Plan is a so-called "401(k) plan" and, therefore, a
      portion of your contribution can, at your election, be treated as deferred
      income for tax purposes. Amounts of allowable contributions are subject to
      certain Internal Revenue Code limits, one of which limits annual
      before-tax savings amounts (for 1999, this limit is $10,000). The S&I Plan
      currently permits an 8% maximum savings rate for before-tax amounts.

5.    The W. R. Grace & Co. Savings & Investment Plan Replacement Payment
      Program is designed to "make-up" matching Company contributions that are
      not paid due to the compensation threshold limit under the Internal
      Revenue Code. To be eligible to receive a "make-up" payment each year, an
      executive must participate in the S&I Plan at a rate of at least 6% during
      the entire year until he or she reaches the compensation limit. The
      replacement payment then equals 3% of the year's plan compensation in
      excess of the legally-imposed compensation limit (which is $160,000 for
      1999).

      You may elect to receive your replacement payment by check at the time
      annual incentive compensation awards are paid or credited (which is
      currently in March of the year following the year to which the payment
      relates), or you may elect to defer the replacement payment you would
      otherwise receive. If you choose to defer the payment, you will receive
      earnings credited under the Deferred Compensation Program.

6.    The W. R. Grace & Co. Long-Term Disability Income Plan ("LTD Plan"). You
      will become eligible to participate in the LTD Plan on a voluntary and
      contributory basis on the first of the month following or coincident with
      your date of employment. Generally, the LTD Plan provides for a monthly
      income of 60% of base monthly
<PAGE>

Robert M. Tarola                     5/3/99                              Page 7
- --------------------------------------------------------------------------------

      earnings should you become disabled, within the meaning of the Plan. The
      maximum monthly benefit under the Plan is $30,000.

7.    Executive Salary Protection Plan ("ESP Plan"). Consistent with your status
      as a senior officer of the Company, beginning with the first date of your
      employment with the Company, you will commence participation in the ESP
      Plan. Under the ESP Plan, in the event of your death while employed by the
      Company and prior to age 70, the Company will continue to pay a portion of
      your base salary to your beneficiary(ies) for a period of time depending
      upon your age at death. This Plan also provides certain disability
      benefits which are supplemental to the Company's LTD Plan.

8.    The W. R. Grace & Co. Voluntary Group Accident Insurance Plan. You will
      become eligible to participate in this Plan effective on the first date of
      employment. Participation is voluntary and requires employee
      contributions. Under the terms of the Plan, you may elect coverage of
      $10,000 through $500,000. Coverage is available on an individual basis or
      under a family plan.

9.    The W. R. Grace & Co. Business Travel Accident Insurance Plan. You will
      become a participant in this Plan effective on the first date of your
      employment with the Company. The Plan provides protection against death,
      permanent total disability or dismemberment. The principal sum is 5 times
      your annual base salary (with a maximum principal sum of $1,500,000). In
      your case, as in the case of other executives, the usual requirements that
      you be away from home or normal place of work and that you be on Company
      business do not apply in order to be eligible for coverage.

10.   The W. R. Grace & Co. Group Term Life Insurance Program. You will
      participate in the Company's basic group term life insurance plan under
      which coverage is 1.5 times your annual base salary.

      Supplemental life insurance coverage, which is voluntary, is also
      available at moderate rates based on your age, up to an additional 3 times
      your annual base salary (with a maximum of $1,500,000 of supplemental
      coverage). Dependent life insurance is also available to your spouse and
      unmarried dependent children to age 19 (or to age 23 if the child
      regularly attends school full-time).

11.   Personal Excess Liability Insurance is effective on the first day of
      employment, as an officer of the Company, for a $6,000,000 limit of
      liability. Coverage is for personal liability claims made against you or a
      family member for bodily injury, property damage, and personal injury. The
      policy extends liability coverage over and above what is covered by the
      primary underlying liability coverage contained in your homeowners,
      automobile, watercraft and recreational vehicle insurance policies.

12.   The W. R. Grace & Co. Group Medical Plan is effective on the first day of
      employment and offers protection to you, your spouse and unmarried
      children to age 19 (age 23 if the child regularly attends a qualified
      school on a full-time basis). The Baltimore/ Washington network medical
      plan utilizes an established network of doctors and hospitals in the area.
      Employees have a choice of two different plan options and a total of four
      different providers of coverage. The Point of Service (POS) option allows

- --------------------------------------------------------------------------------

      you the choice to use a network provider or the freedom to go outside the
      network for medical care; an HMO option requires that you use network
      providers only. The POS option is provided by Aetna U.S. Healthcare and
      the three local HMO options are provided by Freestate Health Plans, M.D.
      IPA and Kaiser Permanente. Employees and their family members must choose
      a primary care physician who will oversee all of their medical needs. Your
      cost for participation in 1999 and hereafter, under the current plan
      provisions, will be 40% of the monthly premium.

      You will also have the opportunity to contribute to a flexible spending
      account up to $5,000 per year.

      An employee hired after January 1, 1993, qualifies for post-retirement
      medical coverage if he or she has at least 10 years of service at
      retirement (age 55 or later). Qualification for this coverage gives the
      retiree access to medical coverage in the Grace plan, but the retiree is
      expected to pay 100% of the premium cost of this coverage. Premium cost is
      determined annually based on experience. Actual claims dollars are paid by
      the Company.

13.   The W. R. Grace & Co. Dental Plan is fully paid for by the Company and
      provides coverage for you and your eligible family members from on the
      first day of employment. Benefits under the plan reflect whether dental
      services are obtained from an in-network or out-of-network provider.

14.   Executive Registry Program. Under this Program you will have access to a
      network of medical services offered by leading hospitals and medical
      centers in large cities throughout the U.S. and abroad. These hospitals
      and medical centers serve as sources where members can obtain high-quality
      emergency medical care while traveling or temporarily living away from
      home either in the U.S. or abroad.

FINANCIAL COUNSELING PROGRAM

As an officer of the Company, you will be eligible to participate in the
Company's Financial Counseling Program. This Program provides you with financial
and estate planning and income tax preparation assistance. The Company will pay
up to $4,000 per calendar year for reasonable, supportable expenses, except that
the maximum amount for the first year of your participation will be $9,000.

COMPANY CAR

The Company will arrange for you to lease, at the Company's expense, an
automobile for use on Company business and for your personal use. The terms of
the coverage will be the same as those provided for other officers of the
Company, including a purchase price cap of $35,000.

EXECUTIVE PHYSICAL PROGRAM

As an officer of the Company, you will be eligible to receive a Company-paid
annual executive physical examination.
