Section 2(b) of the Agreement shall be amended by the insertion of "(i)" immediately prior to the heading "ACQUISITION OF SECURITIES", the renumbering of sub-clauses (i) and (ii) to (A) and (B), and by the insertion of the following at the end thereof: "(ii) PERMITTED HEDGING TRANSACTIONS. Except as otherwise provided herein, the Portfolio Manager is authorized, on behalf of the Issuer, to enter into, amend, extend, assign, cancel or terminate Permitted Hedging Transactions from time to time. The Issuer understands and agrees to be bound by the terms of any such action taken with respect to a Permitted Hedging Transaction pursuant to the authority granted to the Portfolio Manager by Page 2 this Agreement, not withstanding a subsequent termination of this Agreement as provided herein." 2.6.

Section 4 of the Agreement shall be amended (i) by replacing the name "ARM Capital Advisors, LLC" appearing in the heading thereof with the name "BlackRock Financial Management, Inc.", (ii) by replacing the third sentence thereof with the following: "The Agent hereby consents to the appointment of BlackRock Financial Management, Inc. ("BlackRock"), as exclusive investment sub-Portfolio manager Page 3 to the Portfolio pursuant to the terms of that certain Investment Manager Agreement between ARM Financial Group, Inc. and BlackRock dated as of March 9, 1999, a copy of which has been furnished to the Agent." And (iii) by replace the last sentence thereof with the following: "Notwithstanding any such delegation of its obligations hereunder by the Portfolio Manager, the Portfolio Manager may continue to exercise all of its rights under this Agreement as if such delegation had not occurred, the Portfolio Manager's rights and obligations under this Agreement shall remain unchanged, and the Portfolio Manager shall remain solely responsible for the performance of its obligations hereunder." 2.8. Section 5(a)(2) of the Agreement shall be amended by the insertion of the following in the third line thereof immediately following "Short-Term Investments": "or to the satisfaction of payment obligations arising under or in connection with Permitted Hedging Transactions, in each case" 2.9. Section 5(b)(4) of the Agreement shall be amended to read in its entirety as follows: "(4) (a) to counterparties on Permitted Hedging Transactions for the payment of any amounts due and payable thereunder or in connection therewith and (b) to the Agent, for distribution to or for the account of the Certificateholders and Letter of Credit Banks for the payment of the accrued and unpaid Certificate Yield due on such Settlement Date or any prior Settlement Date;" 2.10. Section 7 of the Agreement shall be amended by the insertion therein of a new Section 7(n) which shall read in its entirety as follows: "PERMITTED HEDGING TRANSACTIONS. The Portfolio Manager agrees to maintain in effect all licenses, qualifications and franchises required under law or regulation in order to direct the investment in, manage and service each Permitted Hedging Transaction and will comply in all material respects with all other laws or regulations relating to such activity, in each case except where the failure to perform such obligations or maintain such qualifications would not be likely to have a material and adverse effect on (i) the Issuer's rights under a Permitted Hedging Transaction or (ii) the ability of the Portfolio Manager to perform its obligations under the Agreement. The Portfolio Manager (acting on the Issuer's behalf) will, subject to compliance with all laws and regulations, enforce the Issuer's rights under each Permitted Hedging Transaction in accordance with its respective terms and make to any counterparty thereto such reasonable demands and requests for information and reports or for action as the Page 4 Issuer is entitled to make thereunder. The Portfolio Manager shall instruct counterparties to Permitted Hedging Transactions to direct payments due to the Issuer from time to time thereunder (or in connection therewith) directly to the Custodial Account and shall mark its records with respect to such transactions with a legend that a security interest in the payments due to the Issuer from time to time thereunder (or in connection therewith) has been granted to the Agent, pursuant to the Pledge Agreement for the benefit of the Certificateholders. The Portfolio Manager agrees to update (in a manner satisfactory to the Agent) the reporting practices performed pursuant to Section 7(f) of the Agreement to account for the full and proper inclusion of reporting relating to Permitted Hedging Transactions (and counterparties thereto) in a manner consistent with the reporting performed for Securities and the Obligors thereof." 2.11. The Investment Guidelines (attached to the Agreement as Exhibit A) shall be amended as follows: (a) The "Non-Speculative Hedging Instruments" line item appearing at the bottom of the table on page one of the Investment Guidelines shall be deleted together with footnote (5) relating thereto. (b) Page three of the Investment Guidelines shall be amended by adding the following to the end thereof "5. Securities lending shall be permitted, PROVIDED that such securities lending shall be subject to terms and conditions satisfactory to the Agent, including, without limitation, satisfactory documentation providing that the Agent will continue to have a first priority perfected security interest in any such securities or in any cash or cash equivalents collateralizing such securities lending arrangements." (c) The first paragraph under the heading "Aggregate Portfolio Risk Parameters" on page three of the Investment Guidelines shall be amended by the insertion of the following at the end thereof: "The effective duration of each security will be measured after giving effect to any Non-Speculative Hedging Instruments paired therewith; PROVIDED that, for Non-Speculative Hedging Instruments that are in-the-money at the time of measurement, the counterparty to such Non-Speculative Hedging Instrument must be rated at least A3/A-." Page 5 (d) The second sentence of the second paragraph under the heading "Aggregate Portfolio Risk Parameters" on page three of the Investment Guidelines shall be deleted and replaced with the following: "The average credit quality is calculated as the weighted average of the credit quality of the individual securities and Non-Speculative Hedging Instruments within the portfolio, with securities being weighted by their respective book values or market values as appropriate per the custodial arrangement and Non-Speculative Hedging Instruments being weighted as set forth below under the section entitled, 'Non-Speculative Hedging Instruments.'" (e) The following sentence shall be inserted immediately following the third sentence of the third paragraph under the heading "Aggregate Portfolio Risk Parameters" on page three of the Investment Guidelines: "If an individual security or counterparty has an NAIC rating but no Moody's or S&P rating, then the following numerical values shall correspond to its NAIC rating: NAIC1-8, NAIC2-12, NAIC3-15." (f) The section entitled "Non-Speculative Hedging Instruments" on page five of the Investment Guidelines shall be amended to read in its entirety as follows: "Caps, floors, swaps and similar transactions (or combinations thereof) may only be used as part of a hedging program to explicitly manage the interest rate risk profile of the Portfolio, may only be written if covered by specified securities (i.e., caps/floors at lifetime maximums/minimums for ARMs), may only otherwise be executed if they directly correspond to an unhedged fixed-rate security held in the Portfolio and will be sold, assigned or terminated prior to maturity as close as practicable to the time, if any, at which the corresponding security is sold from the Portfolio. There is no independent requirement to hedge the securities contained within the Portfolio, but no derivatives may be entered into for speculative purposes. The credit quality of acceptable counterparties (determined by reference to their long-term, unsecured debt rating), at the time of execution of each transaction, will be Aa3/AA- or better (unless otherwise approved by the Agent). If the credit quality of an existing counterparty shall fall below A3/A-, then any outstanding in-the-money hedging transactions with such counterparty will be sold, assigned or terminated prior to maturity as soon as is reasonably practicable. Notwithstanding the foregoing, if and to the extent a master netting agreement has been executed with such counterparty (and the Agent Page 6 determines the netting provisions therein to be enforceable upon a counterparty insolvency), then corrective action will only be required if and as necessary from time to time to eliminate any net in-the-money exposure with respect to the master netting agreement as a whole. Hedging instruments will be valued on an ongoing basis at their mark-to-market value (at the most disadvantageous side of the bid/offer spread) with out-of-the-money transactions being assigned a negative value and in-the-money transactions a positive value. Notwithstanding the foregoing, an in-the-money transaction (or, as appropriate, master netting agreement exposure) with a counterparty whose credit rating is below A3/A- shall be valued at zero. For purposes of calculating the average credit quality of the Portfolio, the only hedging instruments which shall be included are those which are in-the-money and with counterparties rated at least A3/A-. Aggregate exposure to any given counterparty (measured as the sum of in-the-money derivatives exposure plus the fair market value of any and all securities issued by such counterparty and held in the Portfolio) shall not be allowed to exceed 5% of the total value of the Portfolio from time to time." 3. REFERENCES TO PORTFOLIO. For purposes of clarification, all references in the Agreement to the term "Portfolio" shall be deemed to include any and all Permitted Hedging Transactions entered into by or on behalf of the Issuer. 4. CONSENT TO APPOINTMENT OF NEW SUB-PORTFOLIO MANAGER. By signing below, the Agent hereby consents to the appointment of BlackRock Financial Management, Inc. ("BlackRock"), as exclusive investment sub-Portfolio Manager to the Portfolio pursuant to the terms of that certain Investment Manager Agreement dated as of March 9, 1999, a copy of which has been provided to Agent. 5. REPRESENTATIONS AND WARRANTIES. In order to induce the Agent to enter into this Amendment, the Issuer and Portfolio Manager make the following representations and warranties: 5.1. The Portfolio Manager represents and warrants that the representations and warranties set forth in Section 6 of the Agreement are true, correct and complete on the date hereof as if made on and as of the date hereof. 5.2. The Issuer represents and warrants that the execution and delivery of this Amendment have been duly authorized by proper corporate proceedings and that this Amendment and the Agreement (as amended by this Amendment) constitute its valid and binding obligations. 6.

CHOICE OF LAW. THIS AMENDMENT SHALL BE CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS (AND NOT THE LAW OF CONFLICTS) OF THE STATE OF ILLINOIS. 10. EXECUTION IN COUNTERPARTS. This Amendment may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement. IN WITNESS WHEREOF, the Issuer, the Portfolio Manager and the Agent have executed this Amendment as of the date first above written. 312 CERTIFICATE COMPANY By: /s/ William D.
