                  Notes to Consolidated Financial Statements
                             (Dollars in millions)


(a)      The financial statements in this Report are unaudited and should be
         read in conjunction with the consolidated financial statements in the
         Company's 1995 Annual Report on Form 10-K. Such interim 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. Certain amounts in the prior period's consolidated
         financial statements have been reclassified to conform to the current
         basis of presentation.

         The results of operations for the three-month interim period ended
         March 31, 1996 are not necessarily indicative of the results of
         operations for the fiscal year ending December 31, 1996.

(b)      As previously reported, Grace is a defendant in lawsuits relating to
         previously sold asbestos-containing products and anticipates that it
         will be named as a defendant in additional asbestos-related lawsuits
         in the future. Grace was a defendant in approximately 42,900
         asbestos-related lawsuits at March 31, 1996 (44 involving claims for
         property damage and the remainder involving approximately 100,200
         claims for personal injury), as compared to approximately 40,800
         lawsuits at December 31, 1995 (47 involving claims for property
         damage and the remainder involving approximately 92,400 claims for
         personal injury). During the first quarter of 1996, Grace settled one
         property damage lawsuit for a total of $4.0 and two property damage
         lawsuits were dismissed; in addition, approximately 200 personal
         injury claims against Grace were dismissed without payment and $7.1
         was recorded to reflect settlements in approximately 2,100 personal
         injury claims.

         Based upon and subject to the factors discussed in Note 2 to Grace's
         consolidated financial statements for the year ended December 31,
         1995, Grace estimates that its probable liability with respect to the
         defense and disposition of asbestos property damage and personal
         injury lawsuits and claims pending at March 31, 1996 and December 31,
         1995, and personal injury lawsuits and claims expected to be filed
         through 1998, is as follows:

             Consolidated Balance Sheet.
         (2) Included in "Other assets" in the Consolidated Balance Sheet.
         (3) The decrease from December 31, 1995 reflects the receipt of net
             insurance proceeds of $12.6 and the reclassification of $27.1
             from "Asbestos-related insurance receivable" to "Notes receivable
             from insurance carriers - current and noncurrent" as the result
             of a first quarter 1996 settlement of a dispute with an insurance
             carrier.

         At March 31, 1996, settlements with certain insurance carriers
         provided for the future receipt by Grace of $147.3, which Grace has
         recorded as notes receivable (both current and noncurrent) of $136.8,
         net of discounts. In the first quarter of 1996, Grace received net
         proceeds of $23.7 pursuant to settlements with insurance carriers in
         reimbursement for monies previously expended by Grace in connection
         with asbestos-related lawsuits and claims; of this amount, $9.7 was
         received pursuant to settlements entered into in 1995, which had
         previously been classified as notes receivable. Pursuant to
         settlements with two groups of carriers in 1995, Grace will continue
         to receive payments based on future cash outflows for
         asbestos-related lawsuits and claims; such payments are estimated to
         represent approximately $223.3 of the asbestos-related receivable of
         $281.5 at March 31, 1996.

         Grace continues to seek to recover from its excess insurers the
         balance of the payments it has made with respect to asbestos-related
         lawsuits and claims. As part of this effort, Grace continues to be
         involved in litigation with certain of its excess insurance carriers
         (having previously settled with its primary and certain of its excess
         carriers). However, 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 personal injury and property damage lawsuits
         and claims pending at March 31, 1996, as well as personal injury
         lawsuits and claims expected to be filed through 1998. Consequently,
         Grace believes that the resolution of its asbestos-related litigation
         will not have a material adverse effect on its consolidated results
         of operations or financial position.

         For additional information, see Note 2 to the consolidated financial
         statements in the Company's 1995 Annual Report on Form 10-K.

(c)      As previously reported, in February 1996 Grace and Fresenius AG
         (Fresenius) entered into a definitive agreement to combine National
         Medical Care, Inc. (NMC), Grace's principal health care subsidiary,
         with Fresenius' worldwide dialysis business (FWD) to create Fresenius
         Medical Care AG (FMC).  The combination would follow the borrowing
         and/or assumption of debt aggregating approximately $2.3 billion by
         NMC, a tax-free distribution of the net cash proceeds by NMC to Grace,
         and a tax-free distribution by the Company, with respect to each share
         of its Common Stock, of one share of a newly formed corporation holding
         all of Grace's businesses (principally its packaging and specialty
         chemicals businesses) other than NMC.  As a result of these
         transactions, the holders of the Company's Common Stock would own 100%
         of the packaging and specialty chemicals company and would be allocated
         an aggregate of approximately 44.8% of FMC's ordinary shares, and
         Fresenius and other shareholders would be allocated 55.2% of such
         shares.  The holders of the Company's Common Stock would also own
         preferred stock, the value of which would be linked to the performance
         of FMC. It is expected that the various transactions will be completed
         by the third quarter of 1996.  See Note 7 to the  consolidated
         financial statements in the Company's 1995 Annual Report on Form 10-K
         for additional information.

         Grace classified its health care business as a discontinued operation
         in the second quarter of 1995. Summary results of operations for the
         health care business are as follows:

         The operating results of Grace's cocoa business and other
         discontinued operations have been charged against previously
         established reserves and are therefore not reflected in the above
         results.

         The net operating income of the health care business reflects an
         allocation of Grace's interest expense ($26.8 and $20.1 for the first
         quarters of 1996 and 1995, respectively) based on a ratio of the net
         assets of the health care business as compared to Grace's total
         capital. Taxes have been allocated to the health care business as if
         it were a stand-alone taxpayer; however, these allocations are not
         necessarily indicative of the taxes attributable to the health care
         business in the future. For the 1995 period, net operating income of
         the health care business also reflects an allocation of Grace's
         health care-related research expenses (Grace management initiated the
         phase-out of certain of its health care research programs in the third
         quarter of 1995).

                                    (Dollars in millions)


         Minority interest consists of a limited partnership interest in Grace
         Cocoa Associates, L.P. (LP). LP's assets consist of Grace Cocoa's
         worldwide cocoa and chocolate business, long-term notes and demand
         loans due from various Grace entities and guaranteed by the Company
         and its principal operating subsidiary, and cash. LP is a separate
         and distinct legal entity from each of the Grace entities and has
         separate assets, liabilities, business functions and operations. For
         financial reporting purposes, the assets, liabilities, results of
         operations and cash flows of LP are included in Grace's consolidated
         financial statements as components of discontinued operations and the
         outside investors' interest in LP is reflected as a minority
         interest. The intercompany notes held by LP are eliminated in
         preparing the consolidated financial statements and, therefore, have
         not been classified as pertaining to discontinued operations.

         The net assets, excluding intercompany assets, of Grace's cocoa
         business and other discontinued operations (classified as current
         assets) and Grace's health care business (classified as noncurrent
         assets) included in the consolidated balance sheet at March 31, 1996,

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


         (a)      Review of Operations

                  (1) Overview:

         Sales and revenues increased 4% in the first quarter of 1996 over the
         first quarter of 1995. Net income for the first quarter of 1996 was
         $63.6 million, a 34% increase as compared to the 1995 first quarter.
         The first quarter of 1995 includes an after-tax charge of $12.5
         million ($20.0 million pretax) for costs associated with the
         termination of the employment agreement of the Company's former
         President and Chief Executive Officer, pension costs resulting from
         the retirement of certain directors, legal and other expenses related
         to the foregoing and other corporate governance activities. Excluding
         the above charge, net income for the first quarter of 1996 would have
         increased 6% as compared to the 1995 first quarter.


                  (2) Operating Results:

         The following table compares results for the specialty chemicals
         segment for the 1996 first quarter to those for the first quarter of
         1995:

                and nonallocable expenses are not reflected in the specialty
                chemicals results.


         Specialty Chemicals

         As noted above, sales and revenues increased 4% in the first quarter
         of 1996 as compared to the 1995 first quarter, reflecting favorable
         volume, price/product mix and currency translation variances
         estimated at 2%, 1% and 1%, respectively. Catalysts and other
         silica-based products, packaging and water treatment product lines
         experienced improved volumes, offset by volume declines in the
         construction and container product lines. Volume increases in
         catalysts and other silica-based products reflected higher sales in
         all regions, especially refinery catalysts in Asia Pacific (due to
         market share gains), polyolefin catalysts in North America and
         silica/adsorbent products in Europe, Asia Pacific and Latin America,
         as a result of new product introductions. Packaging volume increases
         reflected higher sales of bags in North America and Europe, and
         laminates in all regions, particularly Europe; 1996

         Management's Discussion and Analysis of Results of
         Operations and Financial Condition (Continued)


         first quarter sales of films were flat versus the first quarter of
         1995. Volume increases in water treatment reflected higher paper
         industry process chemicals sales in Europe caused by market share
         gains, as well as higher water treatment chemicals sales in Latin
         America. Construction products experienced volume decreases,
         primarily due to the 1995 divestment of the composite material
         business and decreases in sales of fire protection products in North
         America (due to a declining market) and waterproofing products in
         North America (compared to a strong 1995 first quarter that benefited
         from a mild winter) and Europe (due to weak economic conditions in
         the United Kingdom). These decreases were offset by higher sales of
         concrete products in Asia Pacific (caused by a strong construction
         market). Container volume decreases were due to decreased sales of
         can sealing products in Asia Pacific and closure compounds in Europe,
         partially offset by improved sales of can coating products in Latin
         America (as a result of continuing market share penetration).

         Operating income before taxes increased by 23% in the first quarter
         of 1996 as compared to the 1995 first quarter, as cost management
         programs initiated in 1995 are beginning to favorably impact
         operating income within all regions and product lines. North American
         results in the first quarter of 1996 increased, primarily reflecting
         improved operating margins and the volume increases in packaging,
         offset by the volume decreases in construction products noted above.
         European results improved versus the 1995 first quarter, primarily
         due to higher sales of silica/adsorbents products (attributable to
         strong sales of catalyst carriers which are used by customers to
         convert ethylene to ethanol) and in paper industry process chemicals,
         as noted above. These favorable results were offset by lower results
         in packaging, as lower margins and higher operating expenses offset
         the volume increases discussed above. In Asia Pacific, 1996 first
         quarter results were flat versus the first quarter of 1995, as the
         volume increases in refinery catalysts noted above were offset by
         unfavorable results in can sealing products (due to a shortage of
         products to be canned as a result of last year's floods in Southeast
         Asia). Latin American 1996 first quarter results improved versus the
         first quarter of 1995, primarily due to the improved water treatment
         chemical sales noted above, improved volumes in packaging and market
         share gains within container's coating products.


                  (2) Statement of Operations:

         Other Income

         Other income includes interest income, dividends, royalties from
         licensing agreements and equity in earnings of affiliated companies.

         Interest Expense and Related Financing Costs

         Excluding amounts allocated to discontinued operations (as discussed
         in Note (c) to the consolidated financial statements in this Report),
         interest expense and related financing costs of $18.4 million in the
         first quarter of 1996 increased 16% versus the comparable period of
         1995. Including amounts allocated to discontinued operations,
         interest expense and related financing costs increased 26% in the
         first quarter of 1996 over the comparable period of 1995, to $45.2
         million, primarily due to higher debt levels.

         Operations and Financial Condition (Continued)


         See "Financial Condition:  Liquidity and Capital Resources" below for
         information on borrowings.

         Research and Development Expenses

         Research and development spending decreased 6% in the first quarter
         of 1996 versus the 1995 first quarter, reflecting the cost management
         programs discussed above. Research and development spending continues
         to be directed toward Grace's core specialty chemicals businesses.

         Income Taxes

         The effective tax rate was 37.0% in the first quarter of 1996 versus
         31.1% in the 1995 first quarter, excluding the 1995 first quarter
         charge of $20.0 million pretax ($12.5 million after-tax) for corporate
         governance, as discussed above. The higher effective tax rate in the
         first quarter of 1996 was primarily due to a reduction in the overall
         foreign tax rate in the first quarter of 1995, as the result of a
         reassessment of the valuation allowance for certain deferred tax
         assets.

         (i)    The above operating results do not include interest expense
                allocated to the discontinued health care business of $26.8
                million and $20.1 million for the first quarters of 1996 and
                1995, respectively.

         Sales and revenues for the first quarter of 1996 increased by 10%
         over the comparable period of 1995. These improvements were due to
         increases of 12% and 16% in kidney dialysis services and medical
         products operations, respectively. The increase in kidney dialysis
         services and medical products operations is largely due to the effect
         of acquisitions subsequent to the first quarter of 1995, partially
         offset by the decision, effective July 1, 1995, to discontinue
         recognizing incremental revenue that had previously been recorded
         relating to certain dual eligible end stage renal disease patients;
         see the discussion below relating to the Omnibus Budget
         Reconciliation Act of 1993 (OBRA 93). The number of centers providing
         dialysis and related services increased 14%, from 610 at March 31,
         1995 to 693 at March 31, 1996 (581 in North America, 61 in Europe, 36
         in Latin America and 15 in Asia

         Pacific). The improvements in dialysis services and medical products
         operations were partially offset by a 5% decrease in home health care
         revenues resulting from a decrease in infusion therapy revenues due
         to continued managed care pricing pressure.

         Operating income before taxes in the first quarter of 1996 increased
         by 1% over the 1995 first quarter. Operating income benefited from
         the favorable refinancing of a note payable by Grace's health care
         personnel services company, and the phase-out of certain of Grace's
         health care-related research programs. Also, operating income of
         medical products operations improved due to increased revenues, as
         discussed above. These benefits were offset by the effects of OBRA 93
         (which reduced revenues without a commensurate decrease in costs) on
         kidney dialysis services results, as discussed above, and the
         reduction in home health care revenues. Also negatively impacting
         operating income were costs incurred in connection with the
         investigation by the Office of the Inspector General of the U.S.
         Department of Health and Human Services (OIG), as discussed below.

         See below for a discussion concerning certain items relating to NMC's
         operations and the possible material adverse effects of these items.

         OIG Investigative Subpoenas

         In October 1995, NMC received five investigative subpoenas from the
         OIG. The results of the investigation and its impact, if any, cannot
         be predicted at this time. In the event that a U.S. government agency
         believes that any wrongdoing has occurred, civil and/or criminal
         proceedings could be instituted, and if any such proceedings were to
         be instituted and the outcome were unfavorable, NMC could be subject
         to fines, penalties and damages or could become excluded from
         government reimbursement programs. Any such result could have a
         material adverse effect on NMC's financial position or the results of
         operations of NMC and Grace. See Note 7 to the consolidated financial
         statements in the Company's 1995 Annual Report on Form 10-K for
         additional information.

         Intradialytic Parenteral Nutrition (IDPN) Therapy

         NMC administers IDPN therapy to chronic dialysis patients who suffer
         from severe gastrointestinal malfunctions. Since late 1993, Medicare
         claims processors have sharply reduced the number of IDPN claims
         approved for payment as compared to prior periods. NMC believes that
         the reduction in IDPN claims currently being paid by Medicare
         represents an unauthorized policy coverage change. Accordingly, NMC
         and other IDPN providers are pursuing various administrative and
         legal remedies, including administrative appeals, to address this
         reduction. In November 1995, NMC filed a complaint in the U.S.
         District Court for the Middle District of Pennsylvania seeking a
         declaratory judgment and injunctive relief to prevent the
         implementation of this policy coverage change.

         NMC management believes that its IDPN claims are consistent with
         published Medicare coverage guidelines and ultimately will be
         approved for payment. Such claims represent substantial accounts
         receivable of NMC, amounting to approximately $113.0 million and
         $93.0 million as of March 31, 1996 and December 31, 1995,
         respectively, and currently increasing at the rate of approximately
         $6.0 million per month. If NMC is unable to collect its

<PAGE>

         Management's Discussion and Analysis of Results of
         Operations and Financial Condition (Continued)


         IDPN receivable or if IDPN coverage is reduced or eliminated, depending
         on the amount of the receivable that is not collected and/or the nature
         of the coverage change, NMC's business, financial position and
         results of operations could be materially adversely affected.

         In May 1995 the Medicare claims processors circulated a draft
         coverage policy which, if implemented in the form proposed, would
         have limited or precluded continued coverage of parenteral and
         enteral nutrition (PEN) therapies, including IDPN therapy. In April
         1996, the Medicare claims processors issued a revised final version
         of the new coverage policy, which is expected to become effective for
         services billed on and after July 1, 1996. While the new policy
         permits continued coverage of IDPN and other PEN therapies, and while
         the potential impact of the new policy is subject to further
         analysis, NMC believes that the new policy would make it
         substantially more difficult to qualify patients for future coverage
         by, among other things, requiring certain patients to undergo onerous
         and/or invasive tests in order to qualify for coverage. The new
         policy would also eliminate all reimbursement for infusion pumps used
         to administer IDPN therapy. NMC, together with other interested
         parties, plans to seek to effect certain changes in the new policy,
         other than with respect to elimination of reimbursement for revenues
         from infusion pumps, and NMC is developing changes to its patient
         qualification procedures in order to comply with the policy. However,
         if NMC is unable to achieve changes in the new policy, if physicians
         and patients fail to accept the new qualification procedures and/or
         if patients fail to qualify under such procedures, the policy could
         significantly reduce the number of patients eligible for Medicare
         coverage of IDPN and other PEN therapies which would have a material
         adverse effect on NMC's financial position and its results of
         operations.

         OBRA 93

         NMC's business, financial position and results of operations could
         also be materially adversely affected by an adverse outcome in the
         pending litigation concerning the implementation of certain
         provisions of the OBRA 93 relating to the coordination of benefits
         between Medicare and employer health plans in the case of certain
         dialysis patients. See Note 7 to the consolidated financial
         statements in the Company's 1995 Annual Report on Form 10-K for
         additional information.


         (b)      Financial Condition; Liquidity and Capital Resources

         During the first quarter of 1996, the net pretax cash used for
         Grace's continuing operating activities was $47.7 million, versus
         $68.5 million in the 1995 first quarter. The reduction was primarily
         due to improved operating results, offset by net cash outflows of
         $7.5 million in the first quarter of 1996, reflecting amounts paid
         for the defense and disposition of asbestos-related litigation (net
         of amounts received from settlements with certain insurance carriers
         for asbestos-related litigation, as discussed below), as compared to
         a net cash inflow of $69.1 million in the first quarter of 1995. After
         giving effect to the net pretax cash (used for)/provided by
         operating activities of discontinued operations (including an
         increase in the use of operating working capital by NMC in the
         first quarter of 1996) and payments of income taxes, the net cash
         used for operating activities was $91.3 million in the first quarter
         of 1996 versus $62.5 million in the first quarter of 1995.

<PAGE>

         Management's Discussion and Analysis of Results of
         Operations and Financial Condition (Continued)


         Investing activities used $139.8 million of cash in the first quarter
         of 1996, largely reflecting capital expenditures of $112.5 million
         (more than 70% of which relates to Grace's packaging and catalyst and
         other silica-based businesses). Also, investing activities of
         discontinued operations for the first quarter of 1996 used $33.8
         million (compared to $3.3 million used in the 1995 first quarter),
         primarily reflecting the classification of the health care business
         as a discontinued operation in the 1995 second quarter. Management
         anticipates that the level of capital expenditures in 1996 will
         approximate that of 1995.

         Net cash provided by financing activities in the first quarter of
         1996 was $246.8 million, primarily reflecting an increase in total
         debt from December 31, 1995 and proceeds from the exercise of
         employee stock options, offset by the payment of $12.4 million of
         dividends. Total debt was $2,160.6 million at March 31, 1996, an
         increase of $226.8 million from December 31, 1995. Grace's total debt
         as a percentage of total capital (debt ratio) increased from 61.1% at
         December 31, 1995 to 61.9% at March 31, 1996, primarily due to the
         increase in total debt. At March 31, 1996 and December 31, 1995, the
         net assets of the discontinued health care business included $210.6
         million and $226.7 million of debt, respectively.

         Grace expects to receive a substantial amount of cash in 1996 from
         the expected distribution from NMC (as discussed in Note (c) to the
         consolidated financial statements in this Report), the previously
         announced pending sale of the Grace Dearborn water treatment and
         process chemicals business, the pending sale of Grace's transgenic
         plant business (see discussion below), and, to a lesser extent, funds
         generated by operations. Grace expects to apply the cash proceeds
         generated by these transactions to the reduction of borrowings, the
         repurchase of stock and investments in core businesses. The Company
         initiated its previously announced share repurchase program in April
         1996.

         Also in April 1996, Grace announced that it had entered into a
         definitive agreement to sell the transgenic plant business of its
         Agracetus subsidiary to the Monsanto Company for $150.0 million in
         cash.

         Asbestos-Related Matters

         As reported in Note (b) to the consolidated financial statements in
         this Report, Grace is a defendant in lawsuits relating to previously
         sold asbestos-containing products and is involved in related
         litigation with certain of its insurance carriers. In the first
         quarter of 1996, Grace paid $7.5 million for the defense and
         disposition of asbestos-related property damage and personal injury
         litigation, net of amounts received under settlements with certain
         insurance carriers. The balance sheet at March 31, 1996 includes a
         receivable due from insurance carriers, a portion of which is subject
         to litigation, of $281.5 million. Grace has also recorded notes
         receivable of $147.3 million ($136.8 million net of discounts) for
         amounts to be received in 1996 to 2001 pursuant to settlement
         agreements with certain insurance carriers.

<PAGE>

         Management's Discussion and Analysis of Results of
         Operations and Financial Condition (Continued)


         Although the amounts to be paid in 1996 in respect of
         asbestos-related lawsuits and claims cannot be precisely estimated,
         Grace expects that it will be required to expend approximately $40.0
         million (pretax) in 1996 to defend against and dispose of such
         lawsuits and claims (after giving effect to payments to be received
         from certain insurance carriers, as discussed above and in Note (b)
         to the consolidated financial statements in this Report). As
         indicated therein, the amounts reflected in the consolidated
         financial statements with respect to the probable cost of defending
         against and disposing of asbestos-related lawsuits and claims and
         probable recoveries from insurance carriers represent estimates;
         neither the outcomes of such lawsuits and claims nor the outcomes of
         Grace's continuing litigations with certain of its insurance carriers
         can be predicted with certainty.

         Environmental Matters

         There were no significant developments relating to environmental
         liabilities in the first quarter of 1996.

         For additional information relating to environmental liabilities, see
         Note 12 to the consolidated financial statements in the Company's
         1995 Annual Report on Form 10-K.

                           PART II - OTHER INFORMATION

Item 1.           Legal Proceedings.

         (a)      Note (b) to the Consolidated Financial Statements in Part I
of this Report is incorporated herein by reference.

         (b)      In April 1996, the Company received a formal order of
investigation  issued by the Securities and Exchange  Commission  ("Commission")
directing  an  investigation  into,  among  other  things,  whether  the Company
violated  the  federal  securities  laws by  filing  periodic  reports  with the
Commission that contained false and misleading financial  information.  Pursuant
to this formal order of investigation,  the Company has received a subpoena from
the Southeast Regional Office of the Commission requiring the Company to produce
documents  relating to reserves (net of  applicable  taxes)  established  by the
Company and National  Medical Care,  Inc., the Company's  principal  health care
subsidiary  ("NMC"),  during the period from  January 1, 1990 to the date of the
subpoena  (the  "Covered  Period").  The  Company  believes  that all  financial
statements  filed by the Company with the Commission  during the Covered Period,
including the financial statements of NMC included in the NMC Form 10 filed with
the Commission on September 25, 1995, and the consolidated  financial statements
of the Company  filed in the  Company's  Annual Report on Form 10-K for the year
ended December 31, 1995 (all of which financial statements, other than unaudited
quarterly financial  statements,  were covered by unqualified opinions issued by
Price Waterhouse LLP, Grace's independent  certified public  accountants),  have
been fairly

stated,  in  all  material  respects,  in  conformity  with  generally  accepted
accounting  principles.  The Company is  cooperating  with the  Commission.  The
outcome of this  investigation  and its  impact,  if any,  on the Company or NMC
cannot be predicted at this time.

                       (As Amended Through May 10, 1996)


                                   ARTICLE I

                           Meetings of Shareholders

         Section 1.1. Annual Meetings. An annual meeting of the shareholders
of the Corporation, for the election of directors and the transaction of other
business, shall be held annually (a) on the tenth day of May, or (b) if such
day be a Saturday, Sunday or a holiday at the place where the meeting is to be
held, on the last business day preceding or on the first business day after
such tenth day of May, as may be fixed by the Board of Directors, or (c) on
such other date as may be fixed by the Board of Directors.

         Section 1.2. Special Meetings. Except as otherwise expressly
provided by law, a special meeting of the shareholders may be called only by
the Board of Directors, by the Chairman or by the President at any time for
such purpose or purposes and held on such date as may be specified in the
notice thereof.

         Section 1.3. Place and Hour of Meeting. All meetings of shareholders
shall be held at such place within or without the State of New York and at
such hour as may be fixed by the Board of Directors or the officer calling the
meeting.

         Section 1.4. Notice of Meeting. Except as otherwise expressly
provided by law, a notice in writing of each meeting of shareholders shall be
given by or at the direction of the Board of Directors or the officer calling
the meeting to each shareholder of record, personally or by first class mail,
directed to him at his address as it appears on the record of shareholders,
not fewer than ten nor more than fifty days before the date of the meeting.
Each notice shall state the place, date and hour of the meeting and, unless it
is an annual meeting, shall indicate that it is being issued by or at the
direction of the Board of Directors or the officer calling the meeting. If
such notice relates to an annual meeting it need not state the purposes
thereof unless otherwise required by law, the Certificate of Incorporation of
the Corporation or these By-laws. If such notice relates






     
<PAGE>




to a special meeting, it shall state the purpose or purposes for which such
meeting has been called, and no other business shall be transacted at such
special meeting.

         No notice of an adjourned meeting of shareholders need be given
unless otherwise expressly required by law. At any adjourned meeting at which
a quorum is present, any business may be transacted which might have been
transacted at the meeting as originally noticed.

         Notice of meeting need not be given to any shareholder who submits a
signed waiver of notice, in person or by proxy, whether before or after the
meeting. The attendance of any shareholder at a meeting, in person or by
proxy, without protesting prior to the conclusion of the meeting the lack of
notice of such meeting, shall constitute a waiver of notice by him.

         Section 1.5. Quorum. The holders of the shares constituting a
majority in voting power entitled to vote, present in person or by proxy,
shall constitute a quorum at any meeting of shareholders, but no action
required by law, by the Certificate of Incorporation of the Corporation or by
these By-laws to be authorized or taken by the holders of a designated
proportion of the voting power of shares, of the shares of any particular
class or series or of each class or series may be authorized or taken by a
lesser proportion.

         Whether or not there is a quorum at any meeting of the shareholders,
the shareholders present in person or by proxy entitled to cast a majority of
the votes thereat may adjourn the meeting.

         Section 1.6. Voting. Except as otherwise expressly provided by law,
every shareholder of record present in person or by proxy shall be entitled at
every meeting of shareholders to vote, in accordance with and subject to the
provisions of the Certificate of Incorporation of the Corporation, each and
every share of stock of the Corporation standing in his name on the record of
shareholders at the record date fixed as provided in Section 6.3 of these
By-laws or, if no such record date shall have been fixed, then at the time
provided by law.
         Except as otherwise expressly provided by law or by the Certificate
of Incorporation of the Corporation, the vote, at a meeting of the
shareholders duly held and at which a quorum is present, of a majority of the
votes cast at such meeting by the holders of shares entitled to vote shall be
the act of the shareholders.

         Section 1.7.  Business to be Transacted at Annual Meetings.
No business shall be transacted at any annual meeting of the






     
<PAGE>




shareholders, except as may be (a) specified in the notice of the meeting
given by or at the direction of the Board of Directors (including, if so
specified, any shareholder proposal submitted pursuant to the rules and
regulations of the Securities and Exchange Commission), (b) otherwise brought
before the meeting by or at the direction of the Board of Directors or (c)
otherwise brought before the meeting, in accordance with the procedure set
forth in the following paragraph, by a shareholder of record of the
Corporation entitled to vote at such meeting.

         For business to be brought before an annual meeting by a shareholder
pursuant to clause (c) above, the shareholder must have given written notice
thereof to the Secretary of the Corporation, such notice to be delivered or
mailed to, and received at, the principal executive offices of the Corporation
not less than 60 days nor more than 90 days prior to the date of the meeting,
unless the meeting is to take place on a date other than that specified in
clause (a) or (b) of Section 1.1 of these Bylaws, in which event such notice
must be received at the principal executive offices of the Corporation not
later than the close of business on the tenth day following the day on which
the Corporation's notice of the date of the meeting is first given or made to
the shareholders or disclosed to the general public (which disclosure may be
effected by means of a publicly available filing with the Securities and
Exchange Commission). A shareholder's notice to the Secretary shall set forth,
as to each matter the shareholder proposes to bring before the annual meet-
ing, (a) a brief description of the business proposed to be brought before the
annual meeting and of the reasons for bringing such business before the annual
meeting (including, but not limited to, the reasons why the shareholder deems
such business to be beneficial to the Corporation) and, if such business
includes a proposal to amend either the Certificate of Incorporation of the
Corporation or these By-laws, the text of the proposed amendment; (b) the
name and address of the shareholder proposing such business, of any beneficial
owners of shares of stock of the Corporation which are held of record by such
shareholder and of any other shareholders (including beneficial owners) known
by such shareholder to support such proposal; (c) the number of shares of each
class of stock of the Corporation that are held of record and beneficially
owned by the shareholder, any beneficial owners of its shares and any such
other shareholders; (d) a representation that the shareholder is or will be a
holder of record of stock of the Corporation entitled to vote at such meeting
and intends to appear in person or by proxy at such meeting to propose such
business; and (e) any material interest of the shareholder, any beneficial
owner of its shares or any such other shareholders in such business (other
than any interest as shareholders of the Corporation). No business shall be
conducted at any annual meet ing of the shareholders (a) except as specified
in this Section






     
<PAGE>




1.7 or (b) unless, pursuant to the law of the State of New York or any rule or
regulation of the Securities and Exchange Commission, such business may
properly be brought before the meeting.

         If it is determined that any business brought before an annual
meeting of the shareholders is not properly brought before the meeting, the
presiding officer at such meeting shall so de clare to the meeting, in which
event such business shall not be acted upon.

                                   ARTICLE II

                                   Directors

         Section 2.1. Management of Business; Qualifications. Except as
otherwise provided by law or the Certificate of Incorporation of the
Corporation, the business, property and affairs of the Corporation shall be
managed by or under the direction of the Board of Directors. Each director

         Section 2.2.  Number, Election and Term of Office.  The number of
directors constituting the entire Board of Directors shall be such number, not
less than nine nor more than fifty, as may be fixed by a majority of the entire
Board of Directors. No person shall be nominated for election as a director if
such person will have attained the age of 70 prior to the expiration of his or
her term of office*. The directorships shall be divided into three classes,
designated Class I, Class II and Class III, and directors shall be elected and
serve in the manner provided in the Certificate of Incorporation and in these
By-laws.

         No person shall be nominated for election as a director, except as
may be (a) approved by the Board of Directors or (b) nominated by a
shareholder of record of the Corporation entitled to vote at the meeting at
which such person is to be nominated in accordance with the procedure set
forth in the following paragraph.

         A shareholder may nominate a person or persons for election as
directors only if the shareholder has given written notice of its intent to
make such nomination to the Secretary of the Corporation, such notice to be
delivered or mailed to, and received at, the principal executive offices of
the Corporation (a) with respect to an annual meeting of the shareholders, not
less than 60 days nor more than 90 days prior to the date of the meeting,

  Shareholders of the Corporation.





     
<PAGE>




unless the meeting is to take place on a date other than that specified in
clause (a) or (b) of Section 1.1 of these By-laws, in which event such notice
must be received at the principal executive offices of the Corporation not
later than the close of business on the tenth day following the day on which
the Corporation's notice of the date of the meeting is first given or made to
the shareholders or disclosed to the general public (which disclosure may be
effected by means of a publicly available filing with the Securities and
Exchange Commission); or (b) with respect to an election to be held at a
special meeting of the shareholders, not later than the close of business on
the tenth day following the day on which the Corporation's notice of the date
of the meeting is first given or made to the shareholders or disclosed to the
general public (which disclosure may be effected by means of a publicly
available filing with the Securities and Exchange Commission). A shareholder's
notice to the Secretary shall set forth (a) the name and address of the
shareholder who intends to make such nomination, of any beneficial owners of
shares of stock of the Corporation which are held of record by such
shareholder and of any other shareholders (including beneficial owners) known
by such shareholder to support such nomination; (b) the name, age, business
and residence addresses and principal occupation of each person to be nomi-
nated, the class of directorship to which each such person is to be nominated
and the nominee, if any, against whom each such person is to run; (c) the
number of shares of each class of stock of the Corporation that are held of
record and beneficially owned by the shareholder, any beneficial owners of its
shares and any such other shareholders; (d) a representation that the
shareholder is or will be a holder of record of stock of the Corporation en-
titled to vote with respect to the election of directors at such meeting and
intends to appear in person or by proxy at such meeting to nominate such
proposed nominee(s); (e) a description of all material arrangements,
relationships and understandings between the shareholder, any beneficial
owners of its shares or any such other shareholders and each proposed nominee
and between proposed nominees; (f) such other information regarding each
proposed nominee as the Corporation would be required to include in a proxy
statement filed pursuant to the rules and regulations of the Securities and
Exchange Commission; and (g) the written consent of each proposed nominee to
serve as a director of the Corporation if elected, together with an
undertaking, signed by each proposed nominee, to furnish to the Corporation
any information it may request upon the advice of counsel for the purpose of
determining such proposed nominee's eligibility to serve as a director. No
person may be nominated by a shareholder for election as a director of the
Corporation (a) if, pursuant to applicable law or any provision of these
By-laws, such person would be ineligible to serve as a director or (b) if the
election of






     
<PAGE>




such person would violate, or subject the Corporation to liability under, any
applicable law.

         If it is determined that the nomination of any person at any meeting
of the shareholders is not in compliance with this Section 2.2, the presiding
officer at such meeting shall so declare to the meeting, in which event such
nomination shall not be acted upon.

         Section 2.3. Meetings. The Board of Directors shall hold an annual
organization meeting immediately after each annual meeting of shareholders, at
the place where such meeting of shareholders was held (or at such other place
as the Board of Directors shall have designated), for the purpose of electing
officers and for the transaction of such other business as may properly come
before such meeting.

         The Board of Directors may provide for the holding of regular
meetings and may fix the time and place of such meetings. Special meetings may
be called by the Chairman, by the President or by a majority of the directors
then in office.

         Except as hereinabove provided with respect to the annual
organization meeting, the Board of Directors shall hold its meetings at the
principal executive offices of the Corporation in New York, New York, or at
such other place, within or without the State of New York, as the Board of
Directors from time to time may determine, or as may be designated by waivers
of notice thereof signed by all the directors.

         Section 2.4. Notice of Meeting. Notice need not be given with respect
to the annual organization meeting of the Board of Directors (unless such
meeting is to be held at a place other than where the annual meeting of
shareholders is to be held) or with respect to any adjourned meeting of the
Board of Directors. Notice of any regular meeting of the Board of Directors
need not be given unless there is a change in the time or place of such
meeting. Notice of any change in the place of the annual organization meeting
or in the time or place of any regular meeting, and notice of the time and
place of any special meeting of the Board of Directors (a) shall be sent to
each director by first class mail at least three days before the date on which
the meeting is to be held, or (b) shall be sent to each director by telegram,
cablegram, telex or other written form of telecommunication, or delivered or
telephoned to him, at least 24 hours before the time at which such meeting is
to be held. Any notice in writing shall be addressed to the director at his
residence or usual place of business, or at such other address as he may have
designated in a written request filed with the Secretary. Any notice by
telephone shall be communicated to the director or his






     
<PAGE>




representative or answering machine at the telephone number of his residence
or his usual place of business or at such other telephone number as he may
have so designated. Notice of a meeting of the Board of Directors need not
state the purpose thereof, except as otherwise expressly provided by law.

         Notice of meeting need not be given to any director who submits a
signed waiver of notice, whether before or after the meeting, or who attends
the meeting without protesting, prior thereto or at its commencement, the lack
of notice to him.

         Section 2.5. Quorum and Manner of Acting. A majority of the entire
Board of Directors shall constitute a quorum for the transaction of business
at any meeting of the Board of Directors, except that one-third of the entire
Board of Directors shall constitute a quorum for the transaction of any
business relating to any recommendation made by, or other action of, the
Salary, Incentive Compensation and Employee Benefits Committee of the Board
of Directors or the Stock Incentive Committee of the Board of Directors or
any successor to either of such Committees. Except as otherwise expressly
provided by law or by these By-laws, the act of the majority of the directors
present at the time of a vote, if a quorum is present at such time, shall be
the act of the Board of Directors.

         Any one or more members of the Board of Directors may participate in
a meeting of the Board of Directors by means of a conference telephone or
similar communications equipment allowing all persons participating in the
meeting to hear each other at the same time. Participation by such means shall
constitute presence in person at a meeting.

         Whether or not there is a quorum at any meeting, a majority of the
directors who are present may adjourn the meeting to another time or place.
At any such adjourned meeting at which a quorum is present, any business may
be transacted which might have been transacted at the meeting as originally
called.

         On any question, the names of those directors voting each way and
those directors abstaining shall be entered in the min utes if any director
shall so request.

         Section 2.6. Action in Lieu of Meeting. If all the directors consent
in writing to the adoption of a resolution authorizing any action to be taken
by the Corporation, such action shall be as valid corporate action as though
it had been author ized at a meeting of the Board of Directors. Such
resolution and the written consents thereto by the directors shall be filed
with the minutes of the proceedings of the Board of Directors.

         Section 2.7. Resignation and Removal. A director may resign at any
time by giving written notice to the Board of Directors, the Chairman, the
President or the Secretary. Such resignation shall take effect at the time
specified therein or, if no time is specified, immediately upon its receipt by
the Corporation. The acceptance of such resignation shall not be necessary to
make it effective unless otherwise specified therein. A director may be
removed as provided in the Certificate of Incorporation of the Corporation.

         Section 2.8. Vacancies. Any vacancy in the Board of Directors that
results from an increase in the number of directorships may be filled by the
vote of directors constituting a majority of the entire Board of Directors
prior to such increase, and any other vacancy in the Board of Directors may be
filled by the vote of a majority of the directors then in office, even though
the number of directors is less than a quorum, or by the sole remaining
director. Any director elected by the Board of Directors shall hold office
until the next annual meeting of shareholders.


                                  ARTICLE III

                  Executive Committee and Other Committees

         Section 3.1. Appointment and Powers of Committee. The Board of
Directors, by resolution adopted by a majority of the entire Board of
Directors, may designate from its members one or more committees, each
consisting of three or more members. Subject to any limitations imposed by
law or by the Certificate of Incorporation of the Corporation, each committee
shall have such authority as the Board of Directors shall confer, which may in-
clude all the authority of the Board of Directors (including, but not limited
to, that provided for in the Certificate of Incorporation of the Corporation
or these By-laws); provided, however, that no committee shall have authority
as to (a) the submission to shareholders of any action that needs
shareholders' approval under applicable law, (b) the filling of vacancies in
the Board of Directors or any committee or the designation of a committee, (c)
the fixing of compensation of the directors for serving on the Board of
Directors or any committee, (d) the amendment or repeal of these By-laws or
the adoption of new by-laws or (e) the amendment or repeal of any resolution
of the Board of Directors which by its terms shall not be so amendable or
repealable.

         Any reference in these By-laws to action taken or authorized by the
Board of Directors shall include action taken or authorized by a committee
duly designated by the Board of Directors and authorized to act pursuant to
such designation and this Section 3.l.

         Section 3.2. Committee on Officers' Compensation. Pursuant to Section
3.1 of these By-laws, the Board of Directors shall designate a committee to
evaluate the performance of, and to recommend the appropriate level of
compensation for, officers of the Corporation. Such committee shall have
access to an advisor not otherwise serving the Corporation. Each member of
such committee (other than any person who was a member of the Salary, In-
centive Compensation and Employee Benefits Committee of the Board of Directors
on March 7, 1991) shall be an "independent director", as that term is defined
in the following sentence. For purposes of this Section 3.2, an "independent
director" shall mean a person who (a) has not been employed by the Corporation
within the past five years; (b) is not, and is not affiliated with, a firm
that is an advisor or consultant to the Corporation; (c) is not affiliated
with any customer or supplier of the Corporation whose purchases from and/or
sales to the Corporation exceed 3% of the sales and revenues of such customer
or supplier for its most recently completed fiscal year; (d) has no personal
services contract with the Corporation; (e) is not affiliated with a
tax-exempt entity, not otherwise affiliated with the Corporation, that
receives contributions from the Corporation that exceed 3% of such entity's
gross contributions for its most recently completed fiscal year; and (f) is
not a member of the "immediate family" (as defined in Item 404(a) of
Securities and Exchange Commission Regulation S-K) of any person described in
clauses (a) through (e).

         Section 3.3. Meetings. Except as otherwise provided in these By-laws
or by resolution of the Board of Directors, each committee may adopt its own
rules governing the time and place of holding and the method of calling its
meetings and the conduct of its proceedings. Unless otherwise provided by such
rules or by resolution of the Board of Directors, notice of the time and place
of each meeting of a committee shall be mailed, sent or given to each member
of such committee when, and in the same manner as, required in Section 2.4 of
these By-laws with respect to notices of meetings of the Board of Directors.

         Section 3.4. Quorum and Manner of Acting. Except as other wise
specified by the Board of Directors, a majority of the members of each
committee shall constitute a quorum for the transaction of business at any
meeting of such committee, and the act of a majority of the members present at
the time of a vote, if a quorum is present at such time, shall be the act of
such committee. The members of each committee shall act only as a committee,
and the individual members shall have no power as such.

         Any one or more members of a committee may participate in a meeting
of such committee by means of a conference telephone or similar communications
equipment allowing all persons participat-






     
<PAGE>




ing in the meeting to hear each other at the same time. Participation by such
means shall constitute presence in person at a meeting.

         If all the members of a committee consent in writing to the adoption
of a resolution authorizing any action to be taken by the Corporation, such
action shall be as valid as though it had been authorized at a meeting of such
committee. Such resolution and the written consents thereto by the members of
such committee shall be filed with the proceedings of such committee.

         Section 3.5. Term of Office, Resignations, Removals and Vacancies.
The term of office of a committee member shall be as provided in the
resolution of the Board of Directors designating him but shall not exceed his
term as a director. If prior to the end of his term, a committee member should
cease to be a director, he shall cease to be a committee member. Any member
of a committee may resign at any time by giving written notice to the Board of
Directors, the Chairman, the President or the Secretary. Such resignation
shall take effect as provided in Section 2.7 of these By-laws in the case of
resignations by directors. Any member of a committee may be removed from such
committee, either with or without cause, at any time, by resolution adopted by
a majority of the entire Board of Directors. Any vacancy in a committee shall
be filled by the Board of Directors in the manner prescribed by these By-laws
for the original designation of the members of such committee.

                                  ARTICLE IV

such officers and assistant officers shall hold office until the next annual
election and until his successor is elected and qualified, or until his
earlier death, resignation, disqualification or removal. Assistant officers

<PAGE>




         The Chairman and the President shall be chosen from among the Board
of Directors, but the other officers need not be directors. One person may
hold and perform the duties of any two, but not more than two, offices, except
that neither the Chairman nor the President may hold the office of Secretary.

         Section 4.2. Powers and Duties. In addition to any powers and duties
prescribed by other provisions of these By-laws, the officers and assistant
officers shall have such powers and duties as are usually incident to their
respective offices, with such additions and limitations thereto as may from
time to time be prescribed by the Board of Directors or by their respective
superior officers.

         Section 4.3. Resignations, Removals and Vacancies. Any officer or
assistant officer may resign at any time by giving written notice to the
Board of Directors, the Chairman, the President or the Secretary. Such
resignation shall take effect at the time specified therein or, if no time is
specified, immediately upon its receipt by the Corporation. The acceptance of
such resignation shall not be necessary to make it effective unless otherwise
specified therein. Any officer or assistant officer may be removed at any
time, with or without cause, by the Board of Directors or by the person or
persons who appointed him to his office or position, but without prejudice to
any applicable contract rights. A vacancy in any office or position arising
from any cause may be filled for the unexpired portion of the term by the
Board of Directors or by the person or persons authorized to appoint such
officer or assistant officer.

         Section 4.4. Compensation. Subject to Section 3.2 of these By-laws,
the compensation of officers and, to the extent the Board of Directors shall
deem advisable, the compensation of all other employees, agents and
representatives of the Corporation, shall be determined by the Board of
Directors or in accordance with regulations or procedures adopted by it.
Compensation may be contingent or measured in whole or in part upon the
profits of the Corporation or a segment thereof. Provision may also be made
for bonuses and other extra compensation, for the deferment of compensation in
whole or in part and for pension and other retirement benefits. Subject to
Section 3.2 of these By-laws, the Board of Directors may delegate the
authority contained in this Section 4.4 to such officers, employees or agents
of the Corporation as the Board of Directors deems advisable, except that any
profit sharing, extra or deferred compensation, pension and other similar

     CREDIT AGREEMENT, dated as of March 27, 1996, among W. R. GRACE &
CO.-CONN., a Connecticut corporation (the "COMPANY"), W. R. GRACE & CO., a New
York corporation and sole shareholder of the Company ("GRACE NEW YORK"), the
several banks from time to time parties to this Agreement (the "BANKS") and
NationsBank, N.A. (South), as agent for the Banks hereunder (in such capacity,
the "AGENT").

                  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.

     "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.

     "AGREEMENT": this Credit Agreement, as amended, supplemented or otherwise
modified from time to time.

     "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.

     "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 Agent as its prime rate in
effect at its principal office in New 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

                                                                             2




 of the quotations for the day of such transactions received by the Agent
from three federal funds brokers of recognized standing selected by it. If for
any reason the 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 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 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
       ------              ---                     -------

       .450%               BB+ or lower            Ba1 or lower

       .325%               BBB-                    Baa3

       .300%               BBB                     Baa2

       .270%               BBB+                    Baa1

       .240%               A- or higher            A3 or higher

PROVIDED that if on any day the long term senior 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, and PROVIDED,
FURTHER, that if on any day the long term senior 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,

     Period in an aggregate principal amount at any one time outstanding not
     to exceed the amount of such Bank's Commitment, PROVIDED that no Bank
     shall make any Revolving Credit Loan if, (i) after giving effect to such

          (b) Each Borrower agrees that each Bank and the Agent are authorized
     to record (i) the date, amount and Type of each Revolving Credit Loan

     thereto, in the books and records of such Bank or the Agent, as the case
     may be, and in such manner as is reasonable and customary for such Bank
     or the Agent, as the case may be, and a certificate of an officer of such
     Bank or the 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 Agent by any
     Bank at any time, the Revolving Credit Loans made by such Bank to such
     Borrower shall be evidenced by a promissory note of such Borrower,
     substantially in the form of Exhibit A with appropriate insertions as to
     Borrower, payee, date and principal amount (a "REVOLVING CREDIT NOTE"),
     payable to the order of such Bank and in a principal amount equal to the
     lesser of (a) the amount of the initial Commitment of such Bank and (b)

     Bank at any time, such Borrower shall execute and deliver to such Bank a
     Revolving Credit Note conforming to the requirements hereof and executed
     by a duly authorized officer of such Borrower. Each Bank is hereby

     so recorded; PROVIDED that the failure to make any such recording shall
     not in any way affect the obligations of such Borrower hereunder or
     thereunder. Each Revolving Credit Note shall (x) be dated the Closing
     Date, (y) be stated to mature on the Termination Date and (z) provide for
     the payment of interest in accordance with subsection 5.1.

     to 4:00 P.M., New York City time, three Business Days prior to the
     requested Borrowing

                                                                            16



     Date, if all or any part of the requested Revolving Credit Loans are to
     be initially Eurodollar Loans, or (b) prior to 10:00 A.M., New York City
     time, on the requested Borrowing Date, otherwise), specifying (i) the
     amount to be borrowed, (ii) the requested Borrowing Date, (iii) whether
     the borrowing is to be of Eurodollar Loans, ABR Loans or a combination
     thereof and (iv) if the borrowing is to be entirely or partly of
     Eurodollar Loans, the respective amounts of each such Type of Loan and
     the respective lengths of the initial Interest Periods therefor. Each
     borrowing under the Commitments shall be in an amount equal to $5,000,000
     or a whole multiple of $1,000,000 in excess thereof (or, in the case of
     ABR Loans, if the amount of the Available Commitments minus the Aggregate
     Outstanding Bilateral Option Loans is less than $5,000,000, such lesser
     amount). Upon receipt of such notice from such Borrower, the Agent shall
     promptly notify each Bank thereof. Each Bank will make the amount of its
     pro rata share of each such borrowing available to the Borrower at the
     office of the Agent specified in subsection 13.2 prior to 12:00 noon, New
     York City time, on the Borrowing Date requested by such Borrower in funds
     immediately available to the Agent. Such borrowing will then be made
     available to such Borrower on the books of such office with the aggregate
     of the amounts made available to the Agent by the Banks and in like funds
     as received by the Agent.


                       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.

                                                                            17



          3.2 REPORTS TO AGENT; DETERMINATION OF DOLLAR EQUIVALENTS. (a) The
     Borrower shall deliver to the 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 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 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 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 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 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 Agent could purchase the
     specified currency with such other currency at the 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 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 Agent (as the case may be) of any sum adjudged to be so due





     
<PAGE>



                                                                            18



     in such other currency such Bank or the 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 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 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 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 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.


                             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 Agent, in writing, by telex or
     facsimile transmission, or by telephone, confirmed by telex or 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 Agent shall
     promptly notify each Bank by telex or facsimile transmission of the
     contents of each Bid Loan Request received by it.

          (b) Upon receipt of notice from the 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





     
<PAGE>



                                                                            19



     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 Agent, by telephone,
     immediately confirmed by telex or 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 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 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 Agent telephone
          notice to that effect, and the 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 Agent (confirmed as soon as
          practicable thereafter by delivery to the Agent of a Bid Loan
          Confirmation in writing, by telex 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





     
<PAGE>



                                                                            20



          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 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 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 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 Agent's aforesaid address. As
     soon as practicable after each Borrowing Date, the 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 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 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

                                                                            21



     promise and obligation of such Borrower to pay to the Agent, on behalf of
     such Bid Loan Bank, at the office of the 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 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
     Agent, as the case may be, and in such manner as is reasonable and
     customary for such Bank or the Agent, as the case may be, and a
     certificate of an officer of such Bid Loan Bank or the 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 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 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, 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 Eurodollar Rate determined for
     such Interest Period plus the Applicable Margin.

          (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. (a) The Company agrees to pay to the 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 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):

        .0600%                   A- or higher                   A3 or higher

     PROVIDED that if on any day the long term senior 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 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 unsecured debt of the Company is rated by none
     of S&P, Moody's or any Substitute Rating Agency, the Company, the 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
     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.

          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 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 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

                                                                            24



     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.

          (c) If all or a substantial part of the property, assets, business
     or capital stock of any of National Medical Care, Inc., NMC Holding, Inc.
     or Bio-Medical Application Management Company is directly or indirectly
     conveyed, sold, leased, assigned or otherwise disposed of (including by
     merger, consolidation, dividend, distribution, sale of stock, liquidation
     or dissolution) by Grace New York or any of its Subsidiaries (other than
     to Grace New York or any of its Subsidiaries) (a "Disposition"), the
     Commitments shall automatically terminate on the earliest effective date
     of any such Dispositions and the Borrowers shall immediately prepay the
     Loans on such date without premium or penalty, together with accrued
     interest on the amount prepaid to the date of such prepayment.

          (d) The Commitments shall automatically terminate on the date any of
     the commitments under the Existing Agreements are reduced, cancelled or
     terminated.

          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 Agent,
     in the case of Eurodollar Loans, or upon at least one Business Day's
     irrevocable notice to the Agent, in the case of ABR Loans, prepay the
     Loans (other than Bid Loans), in whole or in part, without premium or
     penalty (subject





     
<PAGE>



                                                                            25



     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 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.

          (b) If at any time, the 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.

          (c) All Loans shall be immediately prepaid in full upon the payment
     of any of the principal amount of any loans under the Existing Agreements
     unless the amounts paid under the Existing Agreements are immediately
     reborrowed under the Existing Agreements.

          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 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 Agent irrevocable notice of such election
     (which notice must be received by the 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 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 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 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 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

                                                                            26



     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 Agent shall as soon as practicable notify the Borrowers
     and the Banks of each determination of a Eurodollar Rate. Any change in
     the interest 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 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 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 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
     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 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 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 Agent shall give telecopy or telephonic notice thereof to the
     Borrowers and the Banks as soon as practicable thereafter. If

                                                                            27



     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 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 or utilization 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 Agent or any Bank under
     this Agreement or any Note is insufficient to pay in full all amounts
     then due and payable to the Agent and the Banks under this Agreement and
     the Notes, and the Agent has not received a Payment Sharing Notice (or if
     the 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 Agent and the Banks in
     the following order: FIRST, to the payment of fees and expenses due and
     payable to the Agent in its capacity as 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 Agent has received a Payment Sharing Notice which
     remains in effect, all payments received by the Agent under this
     Agreement or any Note shall be distributed and applied by the 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

                                                                            28



     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 Agent, for the account of the
     Banks, at the 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 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 Agent, the
     Agent may assume that such Bank has made such amount available to the
     Agent on such Borrowing Date, and the Agent may, in reliance upon such
     assumption, make available to the applicable Borrower a corresponding
     amount. If such amount is made available to the Agent on a date after
     such Borrowing Date, such Bank shall pay to the Agent on demand an amount
     equal to the product of (i) the daily average Federal 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 Agent and the denominator of which is 360. A certificate of the 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 Agent by such Bank within three Business Days of such
     Borrowing Date, the 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

                                                                            29



     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 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 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 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

                                                                            30



     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 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 Agent, to the Company
     shall be conclusive in the absence of manifest error.

          (c) Upon request by any Bank, through the 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 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 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 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 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
     authority imposing such tax and the Agent or such Bank (other than a
     connection arising solely from the 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 Agent or any Bank hereunder or under any
     Notes, the amounts so payable to the Agent or such Bank shall be
     increased to the extent necessary to yield to the Agent or such Bank
     (after payment of all Taxes) interest or any such other amounts payable
     hereunder at the rates





     
<PAGE>



                                                                            31



     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 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 Agent the required receipts or other required documentary evidence,
     such Borrower shall indemnify the Agent and the Banks for any incremental
     taxes, interest or penalties that may become payable by the 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 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 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 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 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 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

                                                                            32



     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

     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 Grace New York, 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, and 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 Grace New York) 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.

     Agreement, the Notes and the other Loan

                                                                            33



     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 Grace New York, 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 Grace
     New York or the Company or any of its Subsidiaries) presently pending, or
     to the knowledge of Grace New York or the Company threatened, against or
     affecting Grace New York 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, as discussed in footnote
     (c) to the financial statements included in Grace New York's Quarterly
     Report on Form 10-Q for the period ended September 30, 1995 referred to
     in subsection 6.6, the Company and Grace New York cannot predict at this
     time the results and impact, if any, of the governmental investigation of
     Grace New York's Subsidiary, National Medical Care, Inc., referred to in
     that footnote, and related claims and litigation.

          6.5 OWNERSHIP OF PROPERTIES. Each of Grace New York, the Company and
     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 sheets of Grace
     New York and its Subsidiaries as at December 31, 1994 and December 31,
     1993 and the related consolidated statements of operations, shareholders'
     equity and of cash flows (together with the related notes), included or
     incorporated in Grace New York's Annual Report on Form 10-K filed with
     the SEC for the fiscal year ended December 31, 1994, present fairly in
     all material respects the financial position of Grace New York and its
     Subsidiaries as at such dates and the results of their operations and
     their cash flows for the fiscal years then ended. The unaudited
     consolidated balance sheet of Grace New York and its Subsidiaries as at
     September 30, 1995 and the related unaudited consolidated statement of
     operations for the threeand nine-month interim periods, and the related
     unaudited consolidated statement of cash flows for the nine-month interim
     period, ended on such date, included in Grace New York's Quarterly Report
     on Form 10-Q filed with the SEC for such period, present fairly in all
     material respects the financial position of Grace New York and its
     Subsidiaries as at such date and the results of their operations and
     their cash flows for the threeand nine-month periods, respectively, then
     ended. All of such financial statements, including the notes to such
     financial statements, have been prepared in conformity with GAAP
     (subject,





     
<PAGE>



                                                                            34



     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 Grace New York, neither Grace New York 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
     Grace New York 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.

          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 Grace New York 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 Grace New York 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 Grace New York and its Subsidiaries has
     filed or caused to be filed all tax returns which, to the knowledge of
     Grace New York, are required to be filed and has paid all taxes shown to
     be due and payable on said returns or on any assessments made against it
     or any of its property and all 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 Grace New York 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 Grace New York, no claim is being





     
<PAGE>



                                                                            35



     asserted, with respect to any such tax, fee or other charge which would
     reasonably be expected to have a Material Adverse Effect.

          6.12 INVESTMENT COMPANY ACT; OTHER REGULATIONS. None of Grace New
     York, the Company or any of its Subsidiaries is an "investment company",
     or a company "controlled" by an "investment company", within the meaning
     of the Investment Company Act of 1940, as amended. None of Grace New
     York, the Company or any other 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.

          6.14 ENVIRONMENTAL MATTERS. To the best of the knowledge of Grace
     New York, the operations of Grace New York and its Subsidiaries and all
     parcels of real estate owned or operated by Grace New York or its
     Subsidiaries are in compliance with all Environmental Laws, except where
     the failure to so comply would not reasonably be expected to have a
     Material Adverse Effect.

          6.15 PRINCIPAL SUBSIDIARIES. Set forth on Schedule III are all of
     the Principal Subsidiaries as of the date hereof.

          transaction" (as defined in Section 406 of ERISA or Section 4975 of
          the Code) involving any Plan, (ii) any "accumulated funding
          deficiency" (as defined in Section 302 of ERISA), whether or not
          waived, shall exist with respect to any Plan, (iii) a Reportable

          any Single Employer Plan shall terminate for purposes of Title IV of
          ERISA, (v) the Company or any Commonly Controlled Entity shall, or

                             SECTION 11. THE AGENT

          11.1 APPOINTMENT. Each Bank hereby irrevocably designates and
     appoints NationsBank as the Agent of such Bank under this Agreement and
     the other Loan Documents, and each such Bank irrevocably authorizes
     NationsBank, as the 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 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 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 Agent.

          11.2 DELEGATION OF DUTIES. The 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 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 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 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 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 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 AGENT. The 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, telex or teletype message, 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, Grace New York or any other Borrower), independent
     accountants and other experts selected by the Agent. The 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 Agent. The 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 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 Agent shall not be deemed to have
     knowledge or notice of the occurrence of any Default or Event of Default
     hereunder unless the 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 Agent receives such a notice, the Agent shall give notice
     thereof to the Banks. The 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 Agent shall have
     received such directions, the 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 AGENT AND OTHER BANKS. Each Bank expressly
     acknowledges that neither the 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 Agent
     hereinafter taken, including any review of the affairs of the Loan
     Parties, shall be deemed to constitute any representation or warranty by
     the Agent to any Bank. Each Bank represents to the Agent that it has,
     independently and without reliance upon the 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

                                                                            49



     reliance upon the 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
     Agent hereunder, the 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 Agent or any of its officers, directors, employees,
     agents, attorneys-in-fact or Affiliates.

          11.7 INDEMNIFICATION. The Banks agree to indemnify the Agent in its
     capacity as such (to the extent not reimbursed by the Loan Parties and
     without limiting the obligation of Grace New York, 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 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
     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 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 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 AGENT IN ITS INDIVIDUAL CAPACITY. The Agent and its Affiliates
     may make loans to, accept deposits from and generally engage in any kind
     of business with Grace New York, the Company or any other Borrower as
     though the Agent were not the 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 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 Agent, and the terms "Bank" and "Banks"
     shall include the Agent in its individual capacity.

          11.9 SUCCESSOR AGENT. The Agent may resign as Agent upon 10 days'
     notice to the Banks. If the Agent shall resign as Agent under this
     Agreement and the other Loan Documents, then the Majority Banks shall
     appoint from among the Banks a successor

                                                                            50



     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 Agent, and the term "Agent" shall mean such
     successor agent effective upon its appointment, and the former Agent's
     rights, powers and duties as Agent shall be terminated, without any other
     or further act or deed on the part of such former Agent or any of the
     parties to this Agreement or any holders of the Notes. After any retiring
     Agent's resignation as 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 Agent under this Agreement and the other Loan Documents.


                            SECTION 12. GUARANTEES

          12.1 GRACE NEW YORK GUARANTEE. Grace New York hereby unconditionally
     and irrevocably guarantees to the 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 Agent and the Banks by such Borrowers. This
     guarantee (the "GRACE NEW YORK 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. Grace New York agrees that
     whenever, at any time, or from time to time, it shall make any payment to
     the Agent or any Bank on account of its liability under this Grace New
     York Guarantee, it will notify the Agent and such Bank in writing that
     such payment is made under this Grace New York Guarantee for such
     purpose. No payment or payments made by any Borrower or any other Person
     or received or collected by the 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
     Grace New York under this Grace New York Guarantee, which shall remain
     obligated under this Grace New York 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 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 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 Agent or any Bank on account of its liability under this Company
     Guarantee, it will notify the Agent and such Bank in writing that such
     payment is made under this Company





     
<PAGE>



                                                                            51



     Guarantee for such purpose. No payment or payments made by any such
     Borrower or any other Person or received or collected by the Agent or any
     Bank from any such 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 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 Grace New York Guarantee
     and the Company Guarantee (together, the "GUARANTEES", each a
     "GUARANTEE"), each of Grace New York 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 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 Agent in the exact form
     received by such Guaranteeing Party (duly endorsed by such Guaranteeing
     Party to the Agent, if required), to be applied against the Obligations
     of such Guaranteed Party or Parties, whether matured or unmatured, in
     such order as the 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 Agent or any Bank may be rescinded by the 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,

                                                                            52



     surrendered or released by the 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 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 Agent or any Bank for the payment of the Obligations may be sold,
     exchanged, waived, surrendered or released. Neither the Agent nor any
     Bank shall have any obligation to protect, secure, perfect or insure any
     Lien at any time held by it as security for the Obligations or for the
     obligations of either 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 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 Grace New York, on the one hand, and
     the 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 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 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 Agent is pursuing its
     rights and remedies hereunder against either Guaranteeing Party, the
     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 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,

                                                                            53



     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 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 Agent or any
     Bank upon the insolvency, bankruptcy, dissolution, liquidation or
     reorganization of such Guaranteed Party or upon or as a result of the
     appointment of a receiver, intervenor or conservator of, or trustee or
     similar officer for, such Guaranteed Party or any substantial part of any
     of its property, or otherwise, all as though such payments had not been
     made.

          12.7 PAYMENTS. Each Guaranteeing Party hereby agrees that the
     Obligations will be paid to the Agent for the benefit of the Agent and
     the Banks, as the case may be, without set-off or counterclaim in Dollars
     or Alternative Currency, as appropriate, in immediately available funds
     at the office of the Agent located at 270 Park Avenue, New York, New York
     10017.


                           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 Agent, Grace New York 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, Grace New York or of the Borrowers hereunder or thereunder or
     waiving, on such terms and conditions as the 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 (a) 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 (b) 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 Grace New York 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

                                                                            54



     consent of all the Banks, or (c) amend, modify or waive any provision of
     Section 11 without the written consent of the then Agent. Any such waiver
     and any such amendment, supplement or modification shall apply equally to
     each of the Banks and shall be binding upon Grace New York, the
     Borrowers, the Banks, the Agent, all future holders of the Notes, if any,
     and all future obligees under the Loans. In the case of any waiver, Grace
     New York, the Borrowers, the Banks and the 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 Grace New York 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 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 Grace New York
     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 Grace New York 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 Agent
     and such Bank, amend this Agreement, without the consent of any Bank or
     the 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

     of such clauses.

          13.5 PAYMENT OF EXPENSES AND TAXES. The Company agrees (a) to pay or
     reimburse the Agent for all its out-of-pocket costs and expenses incurred
     in connection with the development, preparation and execution of, and any
     amendment, supplement 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 Agent, (b) to
     pay or reimburse each Bank and the Agent for all its costs and expenses
     incurred in connection with the enforcement or preservation of any rights
     under this Agreement, any Notes, the other Loan Documents and any such
     other documents, including, without limitation, fees and disbursements of
     counsel to the Agent and to the several Banks, and (c) to pay, indemnify,
     and hold each Bank and the Agent harmless from, any and all recording and
     filing fees and any and all liabilities with respect to, or resulting
     from any delay in paying, stamp, excise and other transactional taxes, if
     any, which may be payable or determined to be payable in connection with

     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 other
     documents, and (d) to pay, indemnify, and hold each Bank and the Agent
     harmless from and against any and all other liabilities, obligations,
     losses, damages, penalties, actions, judgments, suits, costs, expenses or
     disbursements of any kind or nature whatsoever with respect to the
     execution, delivery and performance by the Loan Parties, and
     administration and enforcement by the Agent and the Banks of this
     Agreement, any Notes and the other Loan Documents and any such other
     documents (all the foregoing, collectively, the "indemnified
     liabilities"), PROVIDED, that the Company shall have no obligation
     hereunder to the Agent or any Bank with respect to indemnified
     liabilities arising from (i) the gross negligence or willful misconduct
     of the Agent or any such Bank, (ii) legal proceedings commenced against
     the 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 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
     Grace New York, the Borrowers, the Banks, the Agent, all future holders
     of the Notes, if any, all future obligees under the Loans and their
     respective successors and assigns, except that neither Grace New York nor
     any Borrower may assign or transfer any of its rights or obligations
     under this Agreement without the prior written consent of each Bank.





     
<PAGE>



                                                                            57



          (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 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 Grace New York, the Borrowers and the 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. Each of Grace New York 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. Each of Grace New York 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 (which
     consent shall not be unreasonably withheld) and upon notice to the 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 Agent) and delivered to the 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

                                                                            58



     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 Agent in
     exchange for any 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 Agent to the
     Company marked "cancelled".

          (d) The 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 Grace
     New York, the Borrowers, the 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 Grace New York, 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 Agent) together with payment to the Agent of a registration and
     processing fee of $500, the 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) Each of Grace New York 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 Grace New York, the
     Company or such Borrower pursuant to this Agreement or which has been
     delivered to such Bank by or on behalf of Grace New York, 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 Agent, Grace
     New York and the Borrowers) that under applicable law and treaties no
     taxes will be required to be withheld by the Agent, Grace New York, 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 Agent, Grace New York and the 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 Agent, Grace
     New York and the Company) to provide the transferor Bank (and, in the
     case of any Purchasing Bank registered in the Register, the Agent, Grace
     New York 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,





     
<PAGE>



                                                                            60



     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 Grace New
     York and the Borrowers, any such notice being expressly waived by Grace
     New York 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 Grace New York or such Borrower. Each Bank
     agrees promptly to notify Grace New York, the Borrowers and the 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.

          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 Grace New York, the Company and the
     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 Grace
     New York, each Borrower, the Agent and the Banks with respect to the
     subject matter hereof, and there are no promises, undertakings,
     representations or warranties by the Agent or any Bank relative to
     subject matter hereof not expressly

     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) Each of Grace New
     York, each Borrower, the 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 Grace New York or such Borrower at its address
          set forth in subsection 13.2 or, with respect to Borrowers other
          than the Company, the Notice of Additional Borrower relating to such
          Borrower or at such other address of which the Agent shall have been
          notified pursuant thereto;

               (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 each of Grace New York and the Company, 1114 Avenue of the
     Americas, New York, New York 10036-7794, Attention: Treasurer, as its
     authorized agent (the "PROCESS AGENT") to receive on behalf of such
     Borrower service of any and all process and documents in any such legal
     action or proceeding





     
<PAGE>



                                                                            62



     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 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 Agent. If
     the Process Agent shall refuse or be prevented from acting as agent,
     notice thereof shall immediately be given by such Borrowers to the 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 Agent, to serve in place of the Process Agent
     and deliver to the Agent written evidence of such substitute agent's
     acceptance of such designation.

          13.13 ACKNOWLEDGMENTS. Each of Grace New York, each Borrower, the
     Agent and the Banks hereby acknowledges that:

          case may be, arising out of or in connection with this Agreement or
          any of the other Loan Documents, and the relationship between Agent
          and Banks, on one hand, and Grace New York and the Borrowers, on the
          other hand, in connection herewith or therewith is solely that of
          debtor and creditor; and

          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 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

                                                          March 29, 1996

Mr. Albert J. Costello
Chairman, President and
   Chief Executive Officer
W. R. Grace & Co.
One Town Center Road
Boca Raton, Florida 33486-1010

Dear Al:

                  The purpose of this letter is to confirm our understanding
with respect to my Employment Agreement ("Employment Agreement"), dated as of
April 1, 1991, with a subsidiary of W. R. Grace & Co. ("Grace"), as follows:

                  1. I hereby conditionally rescind the notice previously
given to you that I had elected to convert the Employment Agreement into a
consulting agreement upon the terms and conditions set forth in Section 7 of
the Employment Agreement.

                  2. In consideration of such conditional rescission, Grace
agrees to extend the Employment Agreement, and I hereby agree to remain in
Grace's employ, until the first to occur of (a) December 31, 1996 or (b) the
disposition of National Medical Care, Inc. ("NMC") by Grace, whether or not
such disposition is in the form of the proposed transaction between Grace and
Fresenius AG ("Fresenius"). During the period that the Employment Agreement
remains in effect, both parties shall continue to be bound by the provisions
thereof (including without limitation the provisions under which I have the
right to convert the Employment Agreement into a consulting agreement);
provided, however, that:

                  (a) I understand and agree that I will not be a participant
         in Grace's Long-Term Incentive Program for the 1996-1998 Performance
         Period or any subsequent Performance Period and that I will not be
         eligible to receive any portion of the pool that has been established
         to provide NMC employees with "stay bonuses" in connection with
         Grace's proposed disposition of NMC (I understand, however, that I
         will be eligible to participate in the portions of the NMC incentive
         compensation pool relating to annual performance and cash flow
         performance, respectively); and

                  (b) In the event the proposed transaction with Fresenius is
         not consummated by December 31, 1996, or in the event that such
         transaction is so consummated but the New Agreement (as defined
         below) is not executed by me and Fresenius by December 31, 1996, the
         conditional rescission referred to above will automatically be
         revoked, and, effective January 1, 1997, the Employment Agreement
         will be converted into a consulting agreement upon the terms and
         conditions set forth in Section 7 of the Employment Agreement.




     

<PAGE>



                  3. Grace management will recommend that I be nominated to
stand for election as a Class II Director of Grace at its 1996 Annual Meeting
of Shareholders, for a term expiring at the 1997 Annual Meeting of
Shareholders. However, I agree to resign, and I hereby tender my resignation,
as a director of Grace, such resignation to be effective on the date of
termination of my employment by Grace as specified in paragraph 2 above.

                  4. In connection with the transaction with Fresenius
referred to in paragraph 2 above, I expect to enter into an agreement ("New
Agreement") providing for my service as an employee of and/or consultant to
NMC (or another affiliate of Fresenius) following completion of such
transaction. I hereby agree as follows in connection with the New Agreement:

                  (a) I agree to negotiate the terms of the New Agreement in
         good faith with representatives of Fresenius.

                  (b) Upon the effectiveness of the New Agreement, the
         Employment Agreement shall terminate and be of no further force and
         effect, except as specified in Section 4.2 thereof (which contains
         covenants as to confidentiality), and I shall have no right to serve
         as a consultant to Grace.

                  If the foregoing correctly sets forth our understanding,
please sign this letter and the accompanying copy as indicated below and
return one copy to me.

                                                     Very truly yours,



                                                     Constantine L. Hampers


Agreed as set forth above:

                          NON-STATUTORY STOCK OPTION

      Under the W. R. Grace & Co. 1994 Stock Incentive Plan (the "Plan")

        Expiration Date:      April 30, 2005

   In accordance with the Plan (a copy of which is attached hereto as Annex

                        100,000 shares on May 2, 1998,

except that it shall become exercisable in full upon the occurrence of any of
the events specified in section 3(g)(iii) of the Employment Agreement dated

Once exercisable, an installment may be exercised (together with any other

and if such shares were granted to you by the Company subject to
restrictions, such restrictions must have lapsed at least six months prior to
such exercise.

   (5) This Option and any right thereunder is nonassignable and
nontransferable except by will or the laws of descent and distribution, and
is exercisable during your lifetime only by you. If you cease to serve the
Company or a Subsidiary, this Option shall terminate as provided in section
6(d) of the Plan, subject, however, to the following:

THIS DOCUMENT CONSTITUTES PART OF A
PROSPECTUS COVERING SECURITIES THAT
HAVE BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933.



     
<PAGE>

       (a) For the purposes of said section 6(d), your service shall be
    deemed to have terminated by reason of retirement if (i) you retire under
    a retirement plan of the Company or a Subsidiary, (ii) the retirement is
    voluntary, and (iii) you have served the Company or a Subsidiary for at
    least five years. Any other retirement may, at the discretion of the
    Company, be deemed to be a resignation.

       (b) In the event you should become incapacitated or die and neither
    you nor your legal representative(s) or other person(s) entitled to
    exercise this Option exercise this Option to the fullest extent possible
    on or before its termination, the Company shall pay you, your legal
    representative(s) or such other person(s), as the case may be, an amount
    of money equal to the Fair Market Value of any shares remaining subject to
    this Option on the last date it could have been exercised, less the
    aggregate purchase price of such shares.

       (c) Notwithstanding any provision of the Plan, in the event (i) you
    voluntarily retire under a retirement plan of the Company or a Subsidiary
    prior to the date on which the first installment of this Option becomes
    exercisable and (ii) you do not continue to serve the Company or a
    Subsidiary until such date, this Option shall terminate as of the date you
    cease to serve.

       (d) In the event you cease to serve as an employee but immediately
    thereafter commence to serve as a consultant and subsequently you cease to
    serve as a consultant for reasons other than those described in clause (i)
    of section 6(d) of the Plan, this Option shall terminate three years after
    the cessation of your service as a consultant, but subject to the
    limitation set forth in the fifth sentence of such section 6(d).

   (6) If you are or become an employee of, or a consultant to, a Subsidiary,
the Company's obligations hereunder shall be contingent on the approval of
the Plan and this Option by the Subsidiary and the Subsidiary's agreement
that (a) the Company may administer this Plan on its behalf and, (b) upon the
exercise of this Option, the Subsidiary will purchase from the Company the
shares subject to the exercise at their Fair Market Value on the date of
exercise, such shares to be then transferred by the Subsidiary to the holder
of this Option upon payment by the holder of the purchase price to the
Subsidiary. Where appropriate, such approval and agreement of the Subsidiary
shall be indicated by its signature below. The provisions of this paragraph
and the obligations of the Subsidiary so undertaken may be waived, in whole
or in part, from time to time by the Company.

   (7) The Plan is hereby incorporated by reference. Terms defined in the
Plan shall have the same meaning herein. This Option is granted subject to
the Plan and shall be construed in conformity with the Plan.
