      (a) Subsection (a) of Section 6.12 ("Financial Covenants") is amended to
      read as follows:
      "Neither CYTEC nor its subsidiaries shall, without the prior written
      consent of ACY, incur any Debt (except for (x) borrowings under the Credit
      Agreement or borrowings under any credit facility or facilities of not
      more than $100 million, in the aggregate, which has replaced, or was
      entered into in lieu of, the Credit Agreement, or any replacement Credit
      Facility (a "Replacement Credit Facility") and (y) borrowing of not more
      than $10 million of Debt other than the Debt referred to in clause (x)),
      (i) if CYTEC is in default of any of the financial covenants set forth in
      Section 6.12(c), or (ii) if at the time CYTEC has less than $200 million
      of Equity (excluding the CYTEC Preferred Stock) and such incurrence of
      Debt would result in CYTEC and its consolidated subsidiaries having (x) a
      ratio of Debt to Equity (with the CYTEC Preferred Stock being treated as
      neither Debt nor Equity for purposes of calculating the ratio) of more
      than 2:1 or (y) Debt in excess of $150 million, or (iii) if at the time
      CYTEC has $200 million or more of Equity (excluding the CYTEC Preferred
      Stock) and such incurrence of Debt would result in CYTEC and its
      consolidated subsidiaries having a ratio of Debt to Equity (with the CYTEC
      Preferred Stock being treated as neither Debt nor Equity for purposes of
      calculating the ratio) of more than 1.5:1. Notwithstanding the foregoing,
      it shall not be a violation of the foregoing covenant if the Debt to
      Equity ratio referred to in clause (ii)(x) above exceeds 2:1 if the only
      Debt of the Corporation and its subsidiaries existing at such time is (x)
      the Credit Agreement and borrowings thereunder or any Replacement Credit
      Facility and borrowings thereunder and (y) borrowings of not more than $10
      million of Debt other than the Debt referred to in clause (x)."
      (b) Subsection (c) of Section 6.12 ("Financial Covenants") is amended to
      read as follows:
      "Except with the written consent of ACY, CYTEC and its consolidated
      subsidiaries shall at all times (or, with respect to clauses (ii) and
      (iii), at all times following the first anniversary of the Effective Date)
      maintain: (i) a ratio of Debt to Equity of not more than 2:1 (with the
      CYTEC Preferred Stock being treated as neither Debt nor Equity for
      purposes of calculating the ratio), provided that it shall not be a
      violation of the foregoing covenant if the Debt to Equity ratio exceeds
      2:1 if the only Debt of the Corporation and its subsidiaries existing at
      such time is (x) the Credit Agreement and borrowings thereunder or any
      Replacement Credit Facility and borrowings thereunder and (y) not more
      than $10 million of Debt other than the Debt referred to in clause (x);
      (ii) Equity of not less than $200 million (with the CYTEC Preferred Stock
      not being treated as Equity); and (iii) a fixed charge coverage ratio
                                       20
      of not less than 3:1 for the average of the Fixed Charge Coverage Ratios
      for the four consecutive fiscal quarters most recently then ended, with
      the ratio being defined as the ratio of (A) consolidated earnings of CYTEC
      before interest, taxes, depreciation, amortization and cash expenditures
      for environmental Liabilities and Liabilities reflected in the OPEB
      Matters Agreement to (B) the sum of the amount of cash expenditures for
      interest, environmental Liabilities, Liabilities reflected in the OPEB
      Matters Agreement and dividends accrued or paid on the CYTEC Preferred
      Stock (the "Fixed Charge Coverage Ratio"). The maintenance covenants in

      amended to read as follows:

      obligations evidenced by bonds, notes, debentures or similar instruments,
      (iii) obligations to pay the deferred purchase price of property or
      services (except trade accounts payable in the ordinary course of
      business), (iv) obligations as lessee which are capitalized in accordance
      with GAAP or which have a term in excess of five years (except obligations
      as lessee under leases existing as of the Effective Date), (v) obligations
      for the payment of money in connection with any letter of credit
      transaction, provided that obligations secured by a letter of credit shall
      not be included in Debt to the extent such amounts have been accrued on
      CYTEC's balance sheet, (vi) guarantees, direct or indirect, of
      indebtedness of others or (vii) any redeemable preferred stock or hybrid
      security which must be, or at the option of the holder may be required to
      be, repaid or refinanced at the end of a term and which is not classified
      as equity under GAAP. For purposes of this Agreement, in calculating the
      amount of "Debt" of CYTEC and its subsidiaries at any time, the entire
      $100 million of the Credit Agreement or any Replacement Credit Facility
      (as defined herein) shall be counted, regardless of whether any or all of
      such amount has been borrowed by CYTEC or its subsidiaries at such time."
      (d) The definition of "Equity" set forth in Section 1.1 ("General") is
      amended to read as follows:

      payment) of any other distribution, direct or indirect, on account
                                       21
      of any shares of any class of capital stock of CYTEC (other than dividends
      on the CYTEC Preferred Stock, dividends on any redeemable preferred stock,
      or dividends to the extent paid in shares of any class to holders of such
      class and other than dividends paid (other than by CYTEC) to CYTEC or one
      of its subsidiaries) or (ii) any payment or distribution (or incurrence of
      any liability to make a payment or distribution) on account of any
      redemption, retirement, purchase or other acquisition, direct or indirect,
      of any shares of any class of capital stock of CYTEC or its subsidiaries
      or Affiliates now or hereafter outstanding (other than redemption of the
      Series C Preferred Stock as permitted by the terms thereof, redemption or
      repurchase of any preferred stock or hybrid security that is treated as
      "Debt" under clause (vii) of the definition of "Debt" contained herein,

      forms of compensation payable to CYTEC's directors, officers and employees
      or, prior to Employee Transfer Date, its prospective employees) to acquire

      (a) Subsection (a) of Section 9 ("Financial Covenants") is amended to read
      as follows:
      Financial Covenants: "(a) Neither the Corporation nor any of its
      subsidiaries shall, without the prior written consent of the holders of
      the Series C Preferred Stock, incur any Debt (as defined in Section 11
      hereof) (except for (x) borrowings under the Credit Agreement or
      borrowings under any Replacement Credit Facility and (y) borrowings of not
      more than $10 million of Debt other than the Debt referred to in clause
      (x)), (i) if the Corporation is in default of any of the financial
      covenants set forth in paragraph (c) of this Section 9, or (ii) if at the
      time the Corporation has less than $200 million of Equity (excluding the
      Series A Preferred Stock, the Series B Preferred Stock, the Series C
      Preferred Stock and any other redeemable preferred stock of the
      Corporation) and such incurrence of Debt would result in the Corporation
      and its consolidated subsidiaries having (x) a ratio of Debt to Equity
      (with the Series C Preferred Stock being treated as neither Debt nor
      Equity for purposes of calculating the ratio) of more than 2:1 or (y) Debt
      in excess of $150 million, or (iii) if at the time the Corporation has
      $200 million or more of Equity (excluding the Series A Preferred Stock,
      the Series B Preferred Stock, the Series C Preferred Stock and any other
      redeemable preferred stock of the Corporation) and such incurrence of Debt
                                       22
      would result in the Corporation and its consolidated subsidiaries having a
      ratio of Debt to Equity (with the Series C Preferred Stock being treated
      as neither Debt nor Equity for purposes of calculating the ratio) of more
      than 1.5:1. Notwithstanding the foregoing, it shall not be a violation of
      the foregoing covenant if the Debt to Equity ratio referred to in clause
      (ii)(x) above exceeds 2:1 if the only Debt of the Corporation and its
      subsidiaries existing at such time is (x) the Credit Agreement and
      borrowings thereunder or any Replacement Credit Facility and borrowings
      thereunder and (y) borrowings of not more than $10 million of Debt other
      than the Debt referred to in clause (x)."
      (b) Subsection (c) of Section 9 ("Financial Covenants") is amended to read
      as follows:
      "(c) Except with the written consent of the holders of the Series C
      Preferred Stock, the Corporation and its consolidated subsidiaries shall
      at all times (or, with respect to clauses (ii) and (iii), at all times
      following the first anniversary of the Effective Date) maintain: (i) a
      ratio of Debt to Equity of not more than 2:1 (with the Series C Preferred
      Stock being treated as neither Debt nor Equity for purposes of calculating
      the ratio); provided, that, it shall not be a violation of the foregoing
      covenant if the Debt to Equity ratio exceeds 2:1 if the only Debt of the
      Corporation and its subsidiaries existing at such time is (x) the Credit
      Agreement and borrowings thereunder and (y) not more than $10 million of
      Debt other than the Debt referred to in clause (x); (ii) Equity of not
      less than $200 million (with the Series C Preferred Stock being treated as
      neither Debt nor Equity); and (iii) a Fixed Charge Coverage Ratio of not
      less than 3:1 for the average of the Fixed Charge Coverage Ratios for the
      four consecutive fiscal quarters most recently then ended. The maintenance
      covenants in this Section 9(c) shall be measured quarterly on a historical
      basis."
      (c) The definition of "Debt" set forth in Section 11 ("Definitions") is
      amended to read as follows:
      ""Debt" shall mean, without duplication, all (i) obligations for borrowed
      money, (ii) obligations evidenced by bonds, notes, debentures or similar
      instruments, (iii) obligations to pay the deferred purchase price of
      property or services (except trade accounts payable in the ordinary course
      of business), (iv) obligations as lessee under leases which are
      capitalized in accordance with GAAP or which have a term in excess of 5
      years (except obligations as lessee under leases existing as of the
      Effective Date), (v) obligations for the payment of money in connection
      with any letter of credit transaction, provided that obligations to pay
      money secured by a letter of credit shall not be included in Debt to the
      extent such obligations have been accrued on the Corporation's balance
      sheet, (vi) guarantees, direct or indirect, of indebtedness of others, and
                                       23
      (vii) any redeemable preferred stock or hybrid security which must be, or
      at the option of the holder may be required to be, repaid or refinanced at
      the end of a term and which is not classified as equity under GAAP. For
      purposes of Section 9 hereof, in calculating the amount of "Debt" of the
      Corporation and its subsidiaries at any time, the entire $100 million of
      the Credit Agreement or any Replacement Credit Facility shall be counted,
      regardless of whether any or all of such amount has been borrowed by the
      Corporation or its subsidiaries at such time."
      (d) The definition of "Equity" set forth in Section 11 ("Definitions") is

      dividends on the Series A Preferred Stock, dividends on the Series B
      Preferred Stock, dividends on the Series C Preferred Stock, dividends on
      any redeemable preferred stock, or dividends to the extent paid in shares
      of any class to holders of such class and other than dividends paid (other

      (ii) any payment or distribution on account of any redemption, retirement,
      purchase or other acquisition, direct or indirect, of any shares of any
      class of capital stock of the Corporation or its subsidiaries or
      affiliates now or hereafter outstanding (other than redemption or
      repurchase of the Series A Preferred Stock and/or the Series B Preferred
      Stock, and redemption of the Series C Preferred Stock as permitted by the
      terms governing such Series of Preferred Stock, redemption or repurchase
