restrictions (other than any Indebtedness secured by Mortgages permitted as described in clauses (i) through (vii) of Section 5.01(a)) plus the aggregate amount (without duplication) of (x) all Non-Guarantor Subsidiary Debt (other than Non-Guarantor Subsidiary Debt described in clauses (i) through (v) of Section 5.02(a)) and (y) all Attributable Debt of the Company and any of its Subsidiaries in respect of Sale and Leaseback Transactions (with the exception of such transactions which are permitted under clauses (i) through (iv) of Section 5.03) does not exceed 15% of Consolidated Net Tangible Assets.

Section 5.02. Limitation On Subsidiary Debt. (a) So long as any Notes are outstanding, the Company will not permit any of its Restricted Subsidiaries that is not a Subsidiary Guarantor to create, assume, incur, Guarantee or otherwise become liable for or suffer to exist any Indebtedness (any Indebtedness of a non-Guarantor Subsidiary of the Company, “Non-Guarantor Subsidiary Debt”), without concurrently Guaranteeing the payment of the Principal of, premium, if any, and interest on the Notes on an unsecured unsubordinated basis. This restriction does not apply to, and there shall be excluded from Indebtedness in any computation under such restriction, Non-Guarantor Subsidiary Debt constituting:

(i) Indebtedness of a Person existing at the time such Person is merged into or consolidated with any Restricted Subsidiary of the Company or at the time of a sale, lease or other disposition of the properties and assets of such Person (or a division thereof) as an entirety or substantially as an entirety to any Restricted Subsidiary of the Company and is assumed by such Restricted Subsidiary; provided that any Indebtedness was not incurred in contemplation thereof and is not Guaranteed by any other Subsidiary of the Company;

(ii) Indebtedness of a Person existing at the time such Person becomes a Restricted Subsidiary of the Company; provided that any Indebtedness was not incurred in contemplation thereof;

(iii) Indebtedness owed to the Company or any Guarantor;

(iv) Indebtedness outstanding on the date of the Indenture or any extension, renewal, replacement or refunding of any Indebtedness existing on the date of the Indenture or referred to in clauses (i), (ii) or (iii); provided that any such extension, renewal, replacement or refunding of such Indebtedness shall be created within 360 days of repaying the Indebtedness referred to in this clause or clauses (i), (ii) or (iii) above and the principal amount of the Indebtedness shall not exceed the principal amount of Indebtedness plus any premium or fee payable in connection with any such extension, renewal, replacement or refunding, so secured at the time of such extension, renewal, replacement or refunding; and

(v) Indebtedness in respect of a Receivables Facility.

(b) Notwithstanding the limitations on Non-Guarantor Subsidiary Debt described in Section 5.02(a), the Company and any of its Restricted Subsidiaries may create, incur, issue, assume or Guarantee Non-Guarantor Subsidiary Debt, without Guaranteeing the Notes, if at the time of such creation, incurrence, issuance, assumption or Guarantee, after giving effect thereto and to the retirement of any Indebtedness which is concurrently being retired, the aggregate amount of all such Non-Guarantor Subsidiary Debt which would otherwise be subject to such restrictions (other than Non-Guarantor Subsidiary Debt which is described in clauses (i) through (v) of Section 5.02(a)) plus the aggregate amount (without duplication) of (x) all Indebtedness secured by Mortgages (not including any such Indebtedness secured by Mortgages described in clauses (i) through (vii) of Section 5.01(a)) and (y) all Attributable Debt of the Company and any of its Subsidiaries in respect of Sale and Leaseback Transactions (with the exception of such transactions which are permitted under clauses (i) through (iv) of Section 5.03) does not exceed 15% of Consolidated Net Tangible Assets.

(c) Any Subsidiary of the Company required to Guarantee the Notes pursuant to Section 5.02(a) or that chooses to Guarantee the Notes shall (i) execute and deliver to the Trustee a supplemental indenture substantially in the Form of Exhibit B or otherwise satisfactory to the Trustee pursuant to which such Subsidiary shall unconditionally Guarantee all of the Company’s obligations under the Notes and the Indenture in respect of the Notes on the terms set forth in the Indenture and (ii) deliver to the Trustee an Opinion of Counsel. The execution by each Subsidiary Guarantor of a supplemental indenture in the form of Exhibit B evidences the Note Guarantee of such Subsidiary Guarantor, whether or not the person signing as an officer of the Subsidiary Guarantor still holds that office at the time of authentication of any Note. The delivery of any Note by the Trustee after authentication constitutes due delivery of the Note Guarantee set forth in the Indenture on behalf of each Subsidiary Guarantor.

Section 5.03. Limitation on Sale and Leaseback. (a) So long as any Notes are outstanding, the Company will not, and will not permit any of its Subsidiaries to, enter into any Sale and Leaseback Transaction unless:

(i) the Sale and Leaseback Transaction is solely with the Company or any of its Subsidiaries;

(ii) the lease is for a period not in excess of 24 months, including renewals;

(iii) the Company or such Subsidiary would (at the time of entering into such arrangement) be entitled as described in clauses (i) through (vii) of Section 5.01(a), without equally and ratably securing the Notes then outstanding under the Indenture, to create, incur, issue, assume or guarantee Indebtedness secured by a Mortgage on such property or assets in the amount of the Attributable Debt arising from such Sale and Leaseback Transaction;

(iv) the Company or such Subsidiary, within 360 days after the sale of property or assets in connection with such Sale and Leaseback Transaction is completed, applies an amount equal to the greater of (A) the net proceeds of the sale of such Principal Property or (B) the fair market value of such Principal Property to (1) the retirement of Notes, other Funded Debt of the Company ranking on a parity with the Notes or Funded Debt of a Subsidiary of the Company or (2) the purchase of property or assets used or useful in its business or to the retirement of long-term indebtedness; or

(v) the Attributable Debt of the Company and its Subsidiary in respect of such Sale and Leaseback Transaction and all other Sale and Leaseback Transactions entered into after the Closing Date (other than any such Sale and Leaseback Transaction as would be permitted as described in clauses (i) through (iv) of this Section 5.03), plus the aggregate principal amount (without duplication) of (x) Indebtedness secured by Mortgages then outstanding (not including any such Indebtedness secured by Mortgages described in clauses (i) through (vii) of Section 5.01(a)) which do not equally and ratably secure the Notes (or secure Notes on a basis that is prior to other Indebtedness secured thereby) and (y) Non-Guarantor Subsidiary Debt (with the exception of Non-Guarantor Subsidiary Debt which is described in clauses (i) through (v) of Section 5.02(a)), would not exceed 15% of Consolidated Net Tangible Assets.

(iii) immediately after giving effect to such deposit on a pro forma basis, no Event of Default, or event that after the giving of notice or

lapse of time or both would become an Event of Default, shall have occurred and be continuing and such deposit shall not result in a breach or violation of, or constitute a default under, any other material agreement or instrument to which the Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound;

(iv) the Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent to the defeasance and discharge under this Section 10.05 have been complied with; and

ARTICLE 8

GUARANTEES

Section 8.01. In General. Article 12 of the Base Indenture will apply to the Notes.

Section 8.02. Additional Provisions. Each Guaranteeing Subsidiary hereby agrees to become a party to the Indenture as a Subsidiary Guarantor and shall have all of the rights and be subject to all of the obligations and agreements of a Subsidiary Guarantor under the Indenture. Each Guaranteeing Subsidiary agrees to be bound by all of the provisions of the Indenture applicable to a Subsidiary Guarantor and to perform all of the obligations and agreements as follows:

(a) Subject to the provisions of this Fifth Supplemental Indenture, each Guaranteeing Subsidiary hereby irrevocably and unconditionally Guarantees on an unsecured unsubordinated basis, the full and punctual payment (whether at stated maturity, upon redemption, purchase pursuant to an offer to purchase or acceleration, or otherwise) of the Principal of, interest on and all other amounts payable under, the Notes, and the full and punctual payment of all other amounts payable by the Company under the Fifth Supplemental Indenture in respect of the Notes. Upon failure by the Company to pay punctually any such amount, each Guarantor shall forthwith on demand pay the amount not so paid at the place and in the manner specified in the Indenture.

(b) The obligations of each Guaranteeing Subsidiary hereunder are unconditional and absolute and, without limiting the generality of the foregoing, will not be released, discharged or otherwise affected by:

any extension, renewal, settlement, compromise, waiver or release in respect of any obligation of the Company under the Indenture or the Notes, by operation of law or otherwise;

ii.

any modification or amendment of or supplement to the Indenture or the Notes;

iii.

any change in the corporate existence, structure or ownership of the Company, or any insolvency, bankruptcy, reorganization or other similar proceeding affecting the Company or its assets or any resulting release or discharge of any obligation of the Company contained in the Indenture or the Notes;

iv.

the existence of any claim, set-off or other rights which such Guaranteeing Subsidiary may have at any time against the Company, the Trustee or any other Person, whether in connection with the Indenture or any unrelated transactions, provided that nothing herein prevents the assertion of any such claim by separate suit or compulsory counterclaim;

any invalidity or unenforceability relating to or against the Company for any reason of the Indenture or the Notes, or any provision of applicable law or regulation purporting to prohibit the payment by the Company of the Principal of or interest on the Notes or any other amount payable by the Company under the Indenture; or

vi.

any other act or omission to act or delay of any kind by the Company, the Trustee or any other Person or any other circumstance whatsoever which might, but for the provisions of this paragraph, constitute a legal or equitable discharge of or defense to such Guaranteeing Subsidiary’s obligations hereunder.

(c) Except as otherwise provided in the Indenture, each Guaranteeing Subsidiary’s obligations hereunder will remain in full force and effect until the Principal of and interest on the Notes and all other amounts payable by the Company under the Indenture have been paid in full. If at any time any payment of the Principal of or interest on the Notes or any other amount payable by the Company under the Indenture is rescinded or must be otherwise restored or returned upon the insolvency, bankruptcy or reorganization of the Company or otherwise, each Guaranteeing Subsidiary’s obligations hereunder with respect to such payment will be reinstated as though such payment had been due but not made at such time.

(d) Each Guaranteeing Subsidiary irrevocably waives acceptance hereof, presentment, demand, protest and any notice not provided for herein, as well as any requirement that at any time any action be taken by any Person against the Company or any other Person.

(e) Upon making any payment with respect to any obligation of the Company under this Article, each Guaranteeing Subsidiary making such payment will be subrogated to the rights of the payee against the Company with respect to such obligation, provided that such Guaranteeing Subsidiary may not enforce either any right of subrogation, or any right to receive payment in the nature of contribution, or otherwise, from any other Guarantor, with respect to such payment so long as any amount payable by the Company hereunder or under the Notes remains unpaid.

(f) If acceleration of the time for payment of any amount payable by the Company under the Indenture in respect of the Notes or the Notes is stayed upon the insolvency, bankruptcy or reorganization of the Company, all such amounts otherwise subject to acceleration under the terms of the Indenture in respect of the Notes are nonetheless payable by the Guaranteeing Subsidiaries hereunder forthwith on demand by the Trustee or the Holders of the Notes.

(g) Notwithstanding anything to the contrary in this Fifth Supplemental Indenture, each Guaranteeing Subsidiary, and by its acceptance of Notes, each Holder, confirms that it is the intention of all such parties that the Note Guarantee of such Guaranteeing Subsidiary not constitute a fraudulent conveyance under applicable fraudulent

conveyance provisions of the United States Bankruptcy Code or any comparable provision of state law. To effectuate that intention, the Trustee, the Holders of the Notes and each Guaranteeing Subsidiary irrevocably agree that the obligations of each Guaranteeing Subsidiary under its Note Guarantee are limited to the maximum amount that would not render such Guaranteeing Subsidiary’s obligations subject to avoidance under applicable fraudulent conveyance provisions of the United States Bankruptcy Code or any comparable provision of state law.

(h)

The Note Guarantee of a Subsidiary Guarantor will terminate upon:

(i)

the release or discharge (other than a discharge through payment thereon) of the Indebtedness of such Subsidiary that resulted in the obligation to Guarantee the Notes pursuant to Section 5.02 Section 5.02(a) (or, in respect of the Subsidiary Guarantors on the Closing Date, release of their guarantees of all of our other Indebtedness);

(ii)

a sale or other disposition (including by way of consolidation or merger) of the Capital Stock of the Subsidiary such that the Subsidiary is no longer a Subsidiary of the Parent Guarantor;

(iii)

defeasance or discharge of the Notes, as provided under Article 10 of the Base Indenture; or

(iv)

if such Subsidiary Guarantor was not required to Guarantee the Notes pursuant to Section 5.02 Section 5.02(a) but did so at its option, then if it requests such release at any time; provided that after giving effect to such release the Company would be in compliance with the covenant set forth in this Section 5.02.

Upon delivery by the Company to the Trustee of an Officers’ Certificate and an Opinion of Counsel, the Trustee will execute any documents reasonably required in order to evidence the release of the Subsidiary Guarantor from its obligations under its Note Guarantee.

[REVERSE OF NOTE]

7.625% SENIOR NOTE DUE 2021

Indenture. This Note is one of the 7.625% Senior Notes due 2021 (the “Notes”) of the Company issued under an Indenture, dated as of May 11, 2010 (the “Base Indenture”), between the Company, AK Holding Corporation (the “Parent Guarantor”) and U.S. Bank, National Association, as Trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), as supplemented by the Fifth Supplemental Indenture dated September 5, 2014 (the “Fifth Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Parent Guarantor, AK Tube LLC (“AK Tube”) and AK Steel Properties, Inc. (“AK Steel Properties” and AK Tube each a “Subsidiary Guarantor” and together the “Subsidiary Guarantors”), as guarantors, the Trustee and the Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered. To the extent that the terms of the Indenture and this Note are inconsistent, the terms of the Indenture shall govern. The aggregate principal amount of the Notes that may be authenticated and delivered under the Indenture, as amended hereby, shall be $430,000,000 on the Closing Date. The Company may, without notice to or the consent of the Holders, create and issue additional Securities having the same terms as, and ranking equally and ratably with, the Notes in all respects and so that such additional Notes will be consolidated and form a single series with, and have the same terms as to status, redemption or otherwise as, the Notes initially issued; provided that if the additional Securities are not fungible with the Notes for U.S. federal income tax purposes, the additional Securities will have a separate CUSIP number.

Interest. The Company promises to pay interest on the principal amount of the Notes at the rate per year described above. Interest on the Notes will accrue from September 16, 2014. Interest on the Notes will be payable semi-annually on April 1 and October 1 of each year, beginning April 1, 2015. The interest so payable and punctually paid or duly provided for, on any interest payment date, will be paid to the Person in whose names the Notes are registered at the close of business on the record date for such interest, which shall be the March 15 or September 15, as the case may be, preceding such interest payment date, except that interest payable at maturity will be paid to the same Persons to whom Principal of the Notes is payable. Interest will be computed on the basis of a 360-day year consisting of twelve 30-day months. The interest period relating to an interest payment date (including the maturity date) shall be the period from, and including, the most recent preceding interest payment date (or, in the case of the first interest period, September 16, 2014) to, but excluding, the relevant interest payment date.

All payments on the Notes, including Principal of, premium, if any, and interest on, will be payable at the Corporate Trust Office of the Trustee, as Paying Agent under the Indenture as set forth in the Indenture.

If any interest payment date, maturity date or redemption date of a Note falls on a day that is not a Business Day, the required payment of Principal and interest may be made on the next succeeding Business Day as if made on the date that the payment was due and no interest will accrue on that payment for the period from and after that interest payment date, maturity date or redemption date, as the case may be, to the date of that payment on the next succeeding Business Day.

Sinking Fund. The Notes will not be subject to any sinking fund.

Optional Redemption. (a) At any time prior to October 1, 2017, the Company may redeem the Notes at its option, in whole at any time or in part, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed plus the Applicable Premium, plus accrued and unpaid interest to the redemption date.

For the purposes of the preceding paragraph, the following terms shall have the following definitions:

“Applicable Premium” means, with respect to any Note on any redemption date, the greater of

(1) 1.0% of the principal amount of such Note, and

(2) the excess, if any of

(a) the present value at such redemption date of (i) the redemption price of such Note at October 1, 2017 (as set forth in the table below), plus (ii) all required interest payments due on such Note through October 1, 2017 (excluding accrued and unpaid interest to the redemption date), computed using a discount rate equal to the Treasury Rate as of such redemption date plus 50 basis points; over

(b) the then outstanding principal amount of such Note.

“Treasury Rate” means, as of any redemption date, the yield to maturity as of such redemption date of United States Treasury securities with a constant maturity (as compiled and published in the most recent Federal Reserve Statistical Release H.15(519) that has become publicly available at least two business days prior to the redemption date (or, if such Statistical Release is no longer published, any publicly available source of similar market data)) most nearly equal to the period from the redemption date to October 1, 2017; provided, however, that if the period from the redemption date to October 1, 2017, is less than one year, the weekly average yield on actually traded United States Treasury securities adjusted to a constant maturity of one year will be used.

(b) At any time on or after October 1, 2017, the Company may redeem the Notes, in whole or in part, at the redemption price for the Notes (expressed as a percentage of principal amount) set forth below, plus accrued and unpaid interest to the redemption date, if redeemed during the twelve-month period commencing on October 1 of the years indicated below:


Year	Redemption Price
2017		103.813	%
2018		101.906	%
2019 and thereafter		100.000	%

(c) At any time prior to October 1, 2017, the Company may redeem up to 35% of the principal amount of the Notes (including any additional Notes) with the net cash proceeds of one or more sales of the Parent Guarantor’s common stock occurring after the Closing Date (to the extent proceeds are contributed to the Company as equity) at a redemption price (expressed as a percentage of principal amount) of 107.625%, plus accrued and unpaid interest to the redemption date; provided that at least 65% of the aggregate principal amount of Notes originally issued on the Closing Date remains outstanding after each such redemption and notice of any such redemption is mailed within 60 days of each such sale of common stock.

(d) No Note of $2,000 principal amount or less shall be redeemed in part. If any Note is to be redeemed in part only, the notice of redemption relating to such Note will state the portion of the principal amount to be redeemed.

WHEREAS, the Indenture provides that under certain circumstances a Subsidiary shall execute and deliver to the Trustee a supplemental indenture pursuant to which the Subsidiary shall unconditionally Guarantee all of the Company’s obligations under the Notes and the Indenture on the terms and conditions set forth herein; and

WHEREAS, pursuant to Section 11.01 of the Base Indenture, the Trustee is authorized to execute and deliver this Supplemental Indenture.

NOW THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt of which is hereby acknowledged, the Guaranteeing Subsidiary, the Company, the Parent Guarantor and the Trustee mutually covenant and agree for the equal and ratable benefit of Holders as follows:

1. Capitalized Terms. Capitalized terms used herein without definition shall have the meanings assigned to them in the Indenture.

2. Guarantee. The Guaranteeing Subsidiary hereby agrees to become a party to the Indenture as a Subsidiary Guarantor and shall have all of the rights

B-1

and be subject to all of the obligations and agreements of a Subsidiary Guarantor under the Indenture. The Guaranteeing Subsidiary agrees to be bound by all of the provisions of the Indenture applicable to a Subsidiary Guarantor and to perform all of the obligations and agreements as follows:

(a) Subject to the provisions of this Supplemental Indenture, the Guaranteeing Subsidiary hereby irrevocably and unconditionally Guarantees on an unsecured unsubordinated basis, the full and punctual payment (whether at stated maturity, upon redemption, purchase pursuant to an offer to purchase or acceleration, or otherwise) of the Principal of, interest on and all other amounts payable under, each Note, and the full and punctual payment of all other amounts payable by the Company under the Indenture in respect of the Notes. Upon failure by the Company to pay punctually any such amount, each Guarantor shall forthwith on demand pay the amount not so paid at the place and in the manner specified in the Indenture.

vii.

any extension, renewal, settlement, compromise, waiver or release in respect of any obligation of the Company under the Indenture or any Note, by operation of law or otherwise;

viii.

any modification or amendment of or supplement to the Indenture or any Note;

ix.

the existence of any claim, set-off or other rights which the Guaranteeing Subsidiary may have at any time against the Company, the Trustee or any other Person, whether in connection with the Indenture or any unrelated transactions, provided that nothing herein prevents the assertion of any such claim by separate suit or compulsory counterclaim;

xi.

any invalidity or unenforceability relating to or against the Company for any reason of the Indenture or any Note, or any provision of applicable law or regulation purporting to prohibit the payment by the Company of the Principal of or interest on any Note or any other amount payable by the Company under the Indenture; or

B-2

xii.

(c) Except as otherwise provided in the Indenture, each Guaranteeing Subsidiary’s obligations hereunder will remain in full force and effect until the Principal of and interest on the Notes and all other amounts payable by the Company under the Indenture have been paid in full. If at any time any payment of the Principal of or interest on any Note or any other amount payable by the Company under the Indenture is rescinded or must be otherwise restored or returned upon the insolvency, bankruptcy or reorganization of the Company or otherwise, each Guaranteeing Subsidiary’s obligations hereunder with respect to such payment will be reinstated as though such payment had been due but not made at such time.

(e) Upon making any payment with respect to any obligation of the Company under this Article, the Guaranteeing Subsidiary making such payment will be subrogated to the rights of the payee against the Company with respect to such obligation, provided that the Guaranteeing Subsidiary may not enforce either any right of subrogation, or any right to receive payment in the nature of contribution, or otherwise, from any other Guarantor, with respect to such payment so long as any amount payable by the Company hereunder or under the Notes remains unpaid.

(f) If acceleration of the time for payment of any amount payable by the Company under the Indenture or the Notes is stayed upon the insolvency, bankruptcy or reorganization of the Company, all such amounts otherwise subject to acceleration under the terms of the Indenture are nonetheless payable by the Guaranteeing Subsidiary hereunder forthwith on demand by the Trustee or the Holders.

(g) Notwithstanding anything to the contrary in this Supplemental Indenture, each Guaranteeing Subsidiary, and by its acceptance of Notes, each Holder, confirms that it is the intention of all such parties that the Note Guarantee of such Guaranteeing Subsidiary not

B-3

constitute a fraudulent conveyance under applicable fraudulent conveyance provisions of the United States Bankruptcy Code or any comparable provision of state law. To effectuate that intention, the Trustee, the Holders and each Guaranteeing Subsidiary irrevocably agree that the obligations of each Guaranteeing Subsidiary under its Note Guarantee are limited to the maximum amount that would not render the Guaranteeing Subsidiary’s obligations subject to avoidance under applicable fraudulent conveyance provisions of the United States Bankruptcy Code or any comparable provision of state law.

3. Notation not Required. Neither the Company nor the Guaranteeing Subsidiary shall be required to make a notation on the Securities to reflect the Note Guarantee or any release, termination or discharge thereof.

4. Counterparts. The parties may sign any number of copies of this Supplemental Indenture. Each signed copy shall be an original, but all of them together represent the same agreement.

5. Effect of Headings. The Section headings herein are for convenience only and shall not affect the construction hereof.

6. The Trustee. The Trustee shall not be responsible in any manner whatsoever for or in respect of the validity or sufficiency of this Supplemental Indenture or for or in respect of the recitals contained herein, all of which recitals are made solely by the Guaranteeing Subsidiary, the Company and the Parent Guarantor.

7. Successors. All agreements of the Guaranteeing Subsidiary in the Indenture, this Supplemental Indenture and the Note Guarantee shall bind its successors. All agreements of the Trustee in this Supplemental Indenture shall bind its successors.

8. No Waiver. Neither a failure nor a delay on the part of either the Trustee or the Holders in exercising any right, power or privilege under this Supplemental Indenture shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise of any right, power or privilege. The rights, remedies and benefits of the Trustee and the Holders herein expressly specified are cumulative and are not exclusive of any other rights, remedies or benefits which either may have under this Supplemental Indenture at law, in equity, by statute or otherwise.

9. Modification. No modification, amendment or waiver of any provision of this Supplemental Indenture, nor the consent to any departure by the Guaranteeing Subsidiary therefrom, shall in any event be effective unless the

B-4

same shall be in writing and signed by the Trustee, and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given. No notice to or demand on the Guaranteeing Subsidiary in any case shall entitle the Guaranteeing Subsidiary to any other or further notice or demand in the same, similar or other circumstance.
