Voting of Collateral Bonds Held by Senior Trustee.  The senior trustee, as holder of collateral bonds, will attend any meeting of holders of first mortgage bonds under the mortgage indenture, as to which it receives due notice, or, at its option, will deliver its proxy in connection with the meeting.  Either at the meeting, or otherwise where the consent of holders of first mortgage bonds is sought without a meeting, the senior trustee will vote or consent with respect to all of the collateral bonds held by it, as directed by the holders of a majority in aggregate principal amount of the outstanding senior debt securities; provided, however, that the senior trustee shall not vote the collateral bonds of any particular series in favor of, or consent to, any action which in the senior trustee’s opinion would materially adversely affect that series of collateral bonds in a manner not shared generally by all other collateral bonds, except upon notification by the senior trustee to the holders of the related series of senior debt securities of the proposal and the receipt of the consent to the proposal of the holders of not less than a majority in principal amount of the outstanding senior debt securities of that series.
Concerning the Senior Trustee.  U.S. Bank National Association (“U.S. Bank”), is the senior trustee under the senior indenture.  U.S. Bank is also the mortgage trustee under the mortgage indenture and a depositary shares representedof our funds.  See “Description of the First Mortgage Bonds -- Concerning the Mortgage Trustee.”  U.S. Bank and its affiliates also provide other banking or investment banking and other financial services to us and our affiliates.  The Trust Indenture Act of 1939, as amended, contains limitations on the rights of U.S. Bank, should it become one of our creditors, to obtain payment of claims in certain cases or to realize on certain property received by it in respect of any such claim, as security or otherwise.  Under the Trust Indenture Act, U.S. Bank is permitted to engage in other transactions with us and our affiliates from time to time, provided that if U.S. Bank acquires any conflicting interests it must eliminate such conflicts upon the occurrence of an event of default under the senior indenture, or else resign.
Book-Entry Securities.  We may initially issue the senior debt securities of any series in the form of one or more global securities under a book-entry only system operated by a depositary receipt,securities depository.  Unless otherwise specified in the applicable prospectus supplement, The Depository Trust Company (“DTC”), New York, New York, will act as securities depository for each series of senior debt securities.  We will issue the senior debt securities as fully-registered securities registered in the name of Cede & Co., DTC’s partnership nominee, or such other name as an authorized representative of DTC may request.  We will issue one fully-registered debt security certificate for each issue of the senior debt securities, each in the aggregate principal amount of such issue, and deposit the certificate with DTC.
DTC is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code, and a “clearing agency” registered pursuant to the provisions of Section 17A of the Securities Exchange Act of 1934.  DTC also facilitates the post-trade settlement among DTC participants of sales and other securities transactions in deposited securities, through electronic computerized book-entry transfers and pledges between direct participants’ accounts.  This eliminates the need for physical movement of securities certificates.  Direct participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations.  DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation (“DTCC”).  DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies.  DTCC is properly endorsedowned by the users of its regulated subsidiaries.  Access to the DTC system is also available to others such as U.S. and non-U.S. securities brokers and dealers, banks, trust companies, and clearing corporations that clear through or accompanied by appropriate instruments of transfer, will be transferable by deliverymaintain a custodial relationship with a direct participant, either directly or indirectly.  The DTC rules applicable to its participants are on file with the same effectSecurities and Exchange Commission.  More information about DTC can be found at www.dtcc.com.

Purchases of debt securities under the DTC system must be made by or through direct participants, which will receive a credit for the debt securities on DTC’s records.  The ownership interest of each actual purchaser of each debt security, the beneficial owner, is in turn to be recorded on the records of direct and indirect participants.  Beneficial owners will not receive written confirmation from DTC of their purchase.  Beneficial owners should, however, receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the direct or indirect participant through which they entered into the transaction.  Transfers of ownership interests in the casedebt securities are accomplished by entries made on the books of a negotiable instrument.
Resignationdirect and Removalindirect participants acting on behalf of Depositary
The depositary may resign at any time by delivering to us notice of its election to do so, and we may at any time remove the depositary, any such resignation or removal to take effect upon the appointment of a successor depositary and its acceptance of such appointment.  Such successor depositary must be appointed within 60 days after delivery of the notice of resignation or removal and must be a bank or trust company having its principal office in the United States of America and having a combined capital and surplus of at least $150,000,000.

To facilitate subsequent transfers, all debt securities deposited by direct participants with DTC are registered in the name of DTC’s partnership nominee, Cede & Co., or depositary shares issuedsuch other name as an authorized representative of DTC may request.  The deposit of debt securities with DTC and their registration in book-entry formthe name of Cede & Co. or such other DTC nominee do not effect any change in beneficial ownership.  DTC has no knowledge of the actual beneficial owners of the debt securities; DTC’s records reflect only the identity of the direct participants to whose accounts such debt securities are credited, which may or may not be the beneficial owners.  The direct and indirect participants will remain responsible for keeping account of their holdings on behalf of their customers.
Conveyance of notices and other communications by DTC to direct participants, by direct participants to indirect participants, and by direct participants and indirect participants to beneficial owners will be evidencedgoverned by onearrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time.
Redemption notices shall be sent to DTC.  If less than all of the debt securities within an issue are being redeemed, DTC’s practice is to determine by lot the amount of the interest of each Direct Participant in such issue to be redeemed.
Neither DTC nor Cede & Co. (nor any other DTC nominee) will consent or vote with respect to debt securities unless authorized by the direct participants.  Under its usual procedures, DTC mails an omnibus proxy to us as soon as possible after the record date.  The omnibus proxy assigns Cede & Co.’s consenting or voting rights to those direct participants to whose accounts debt securities are credited on the record date (identified in a listing attached to the omnibus proxy).
Redemption proceeds, principal payments and interest, premium or other payments on the debt securities will be made to Cede & Co., as DTC’s nominee, or to such other nominee as an authorized representative of DTC may request.  DTC’s practice is to credit direct participants’ accounts upon DTC’s receipt of funds and corresponding detail information from us or our paying agent, if any, in accordance with their respective holdings shown on DTC’s records.  Payments by participants to beneficial owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of such participant and not of DTC, the senior trustee, or us, subject to any statutory or regulatory requirements as may be in effect from time to time.  Payment of redemption proceeds, principal payments and interest, premium or other payments to Cede & Co. (or such other nominee as an authorized representative of DTC may request) is the responsibility of us or our paying agent, if any, disbursement of such payments to direct participants will be the responsibility of DTC, and disbursement of such payments to the beneficial owners will be the responsibility of direct and indirect participants.

DTC may discontinue providing its services as depository with respect to the senior debt securities at any time by giving reasonable notice to us or the senior trustee.  Under such circumstances, in the event that a successor depository is not obtained, senior debt security certificates are required to be printed and delivered.
We may decide to discontinue use of the system of book-entry-only transfers through DTC (or a successor securities depository).  In that event, senior debt security certificates will be printed and delivered to DTC.
The information in this section concerning DTC and DTC’s book-entry system has been obtained from sources that we believe to be reliable, but neither we nor the trustees nor any underwriter takes any responsibility for the accuracy of the information.
Neither we nor the trustees under the indentures will have any responsibility or obligation to any DTC direct or indirect participant or any beneficial owner of a book-entry interest or any other person not shown on the registration books of the trustees as being a holder of the debt securities with respect to:  (1) any senior debt securities; (2) the accuracy of any records maintained by DTC or any DTC direct or indirect participant; (3) the payment by DTC or any DTC direct or indirect participant of any amount due to any beneficial owner of a book-entry interest in respect of the principal or redemption price of or interest on the debt securities; (4) the delivery by DTC or any DTC direct or indirect participant of any notice to any beneficial owner of a book-entry interest which is required or permitted under the terms of the indentures to be given to holders of the senior debt securities; (5) the selection of the owners of a book-entry interest to receive payment in the event of any partial redemption of any senior debt securities; or (6) any consent given or other action taken by DTC or its nominee as holder of the senior debt securities.
DESCRIPTION OF THE FIRST MORTGAGE BONDS
The following is a summary of the material provisions of the first mortgage bonds and the mortgage indenture.  This summary does not purport to be complete and is qualified in its entirety by reference to the more globaldetailed provisions of the mortgage indenture and supplemental indentures, which are incorporated by reference in this prospectus.
General.  Before the release date, we will issue to the senior trustee any series of first mortgage bonds issued as collateral bonds.  Each issue of collateral bonds to the senior trustee will be in a principal amount equal to the principal amount of the senior debt securities issued contemporaneously with the collateral bonds.  Before the release date, we will make payments of the principal of, and premium or interest on, each series of collateral bonds to the senior trustee.  The senior trustee will apply those payments to the satisfaction of all obligations then due on the related series of senior debt securities.
Liens and Titles.  The collateral bonds will be secured by the mortgage indenture equally and ratably with all other bonds issued under the mortgage indenture (except as to any sinking fund or similar fund established for the benefit of bonds of a particular series).  At the time of issuance of each series of the collateral bonds, our counsel will deliver its opinion that willthe mortgage indenture constitutes, except as stated in this paragraph, a valid and direct first lien upon substantially all of the real and fixed property and governmental licenses and permits that we own (including our interests as tenant-in-common), subject only to permissible encumbrances and to the other limitations and exceptions respecting title to real and fixed properties that are stated in their opinion on title described below.  Excepted from the lien are investments in other companies, items of the general character such as would be included on our balance sheet as current assets (unless deposited or required to be deposited with the mortgage trustee), motor vehicles, and timber and minor parcels of real estate.  The term “permissible encumbrances”
15

includes liens upon transmission or distribution line rights-of-way, and certain tax and other liens, easements or leases, and other adverse interests of a nature or of a proportion that would not under ordinary circumstances materially impair the lien of the mortgage indenture or the use of the property.
The mortgage indenture by its terms also covers in general all of our after-acquired property, other than property of the nature excepted from the lien of the mortgage indenture as stated above.  The lien on an after-acquired system may be subject to a prior lien and, in case of merger, to possible limitation to our system at that time.
At the time of issuance of each series of the collateral bonds, our counsel will deliver its opinion that we have good and marketable title to the real and fixed properties described in the mortgage indenture (other than properties disposed of and released under the mortgage indenture and lands described as held only under flowage rights) free and clear of all liens, charges and encumbrances prior to or on behalfa parity with the lien of a depository identifiedthe mortgage indenture, except for and subject only to “permissible encumbrances” and to those exceptions, defects and qualifications which in our counsel’s opinion do not materially affect the security for the collateral bonds or title to or our right to use the properties in the conduct of our business.  The opinion of counsel does not cover the validity of or title to easements or rights-of-way for transmission and distribution lines.
The mortgage indenture does not prevent us from merging or consolidating with another entity, selling all or substantially all of our assets, or engaging in a recapitalization or other comparable transaction as long as (1) the lien of the mortgage indenture and the rights and powers of the mortgage trustee and the bondholders under the mortgage indenture are not impaired; (2) the principal amount of prior lien bonds secured by a prior lien or liens on property of the successor corporation (exclusive of the property that we owned immediately before the merger, consolidation or sale) and outstanding immediately after the consolidation, merger or sale shall not exceed 60% of the cost or fair value, whichever is less, of the property of the character of permanent additions owned by the successor corporation, immediately before such transaction; (3) the earnings applicable prospectus supplement relatingto bond interest of the successor corporation determined as provided in the mortgage indenture, excluding our net earnings, for a period of 12 consecutive calendar months within the 15 consecutive calendar months immediately preceding the first day of the calendar month in which the consolidation, merger or sale is made shall have been in the aggregate at least equal to twice the interest requirements for a period of one year upon all prior lien bonds secured by a prior lien or prior liens on the property of the successor corporation and outstanding immediately after the transaction; and (4) the successor corporation assumes our obligations under the mortgage indenture.  If these conditions are satisfied with respect to any such transaction, we may enter into the transaction.  Although the mortgage indenture limits the principal amount of additional bonds which we may issue, it does not restrict the amount of unsecured debt that we may incur.  Except as described above, the mortgage indenture does not provide any protection to the securities.  Unlessbondholder against a highly leveraged transaction however structured.
Outstanding and until it is exchangedAdditional Bonds:  Under the mortgage indenture, there were outstanding as of December 31, 2012, $872,100,000 principal amount of bonds of various prior series, $22,000,000 of which matured and was repaid in whole or in part for the individual securities represented thereby, a global security may not be transferred exceptFebruary 2013.  Additional bonds without limit as a whole by the depository for the global security to a nominee of such depository or by a nominee of such depository to such depository or another nominee of such depository or by the depository or any nominee of such depository to a successor depository or a nominee of such successor.  Global securitiesaggregate amount may be issued in either registereda principal amount up to (a) 60% of the lesser of cost or bearer formfair value of net permanent additions (electric, gas or steam property acquired after January 1, 1941, less retirements after that date taken at undepreciated cost, subject to certain adjustments) except permanent additions otherwise utilized under the mortgage indenture or restricted under the terms of certain supplemental indentures; (b) the amount of bonds retired or cancelled, except from certain funds; and (c) the amount of cash deposited with the mortgage trustee for the purpose, which cash may thereafter be withdrawn in lieu of the issuance of an equal amount of bonds under clauses (a) or (b) but without any earnings’ test requirement.  Bonds may be issued under clauses (a) and (c), and under certain circumstances under clause (b), only if
16

earnings applicable to bond interest for a period of 12 months within the preceding 15 months have been at least twice the annual interest requirements upon all bonds then applied for and outstanding.
Earnings applicable to bond interest, as defined in the mortgage indenture, for the year ended December 31, 2012, were $239.8 million, resulting in a ratio of 5.59 times the full annual interest requirements upon all bonds then outstanding, and a ratio of 3.63 after the issuance of $500,000,000 principal amount of collateral bonds at an estimated weighted average interest rate of 4.625% per annum (without taking into account the maturing of $22,000,000 of collateral bonds in February 2013 and $125,000,000 of collateral bonds in December 2013).  A difference of 1/8% in the assumed weighted average interest rate on the collateral bonds would change the ratio by approximately 0.034.
The aggregate amount of unbonded bondable property was approximately $689 million as of December 31, 2012, a portion or all of which will be applied as the basis for the issuance of the collateral bonds.  The retirement of bonds of prior series may also be the basis for the issuance of additional collateral bonds.
Release Provisions:  The mortgage trustee may release property which we have sold from the lien of the mortgage indenture upon our deposit of the fair value of the property with the mortgage trustee.  Purchase money obligations so deposited may not exceed 60% of fair value of the released property.  We may withdraw release funds on the basis of the lesser of cost or fair value of net permanent additions applied for the purpose, or the principal amount of bonds that we have surrendered, or we may apply release funds to bond retirement.  Bonds may be redeemed from release funds only when they are subject to redemption and upon payment of the applicable regular redemption premium.  The mortgage trustee may release property certified as no longer necessary in our business and of less than $500,000 value (but not to exceed in the aggregate per year an amount equal to 1% of the outstanding bonds) upon our covenant to deposit the proceeds of sale, if any, and we may withdraw such proceeds upon our covenant to expend the same for permanent additions.
Modification of Mortgage Indenture:  With our consent and the consent of the holders of 70% in principal amount of bonds then outstanding, we and the mortgage trustee may modify the mortgage indenture and the bonds (including the collateral bonds) except as to (a) the due dates, amounts and other terms (other than sinking fund provisions) of payment of principal or interest, or (b) the creation of any lien ranking prior to or on a parity with the lien of the mortgage indenture, or (c) deprivation of any nonassenting bondholder of a lien on the mortgaged property for the security of such bondholder’s bonds, or (d) reduction of the percentage in the amount of bonds required to consent to a modification of the mortgage indenture.  We and the mortgage trustee may also modify the mortgage indenture, without any action on the part of the bondholders, provided that any modification that would adversely affect the rights of the holders of any bonds then outstanding may not become effective until all bonds outstanding at the time of the adoption of the modification have been redeemed or retired.
Concerning the Mortgage Trustee:  The mortgage trustee under the mortgage indenture is U.S. Bank National Association, which is also the senior trustee under the senior indenture and a depositary of our funds.  U.S. Bank and its affiliates also provide other banking or investment banking and other financial services to us and our affiliates.  The Trust Indenture Act of 1939 contains limitations on the rights of U.S. Bank, should it become one of our creditors, to obtain payment of claims in certain cases or to realize on certain property received by it in respect of any such claim, as security or otherwise.  Under the Trust Indenture Act, U.S. Bank is permitted to engage in other transactions with us and our affiliates from time to time, provided that if U.S. Bank acquires any conflicting interests it must eliminate such conflicts upon the occurrence of an event of default under the mortgage indenture, or else resign.
17

Defaults and Notice Thereof:  The following events are defined as “completed defaults” under the mortgage indenture:  (a) default in the payment of the principal of any bond; (b) default continued for 90 days in the payment of any interest upon any bond; (c) default in our covenants with respect to bankruptcy, insolvency, assignment or receivership; or (d) default continued for 90 days after notice to us from the mortgage trustee in the performance of any other covenant, agreement or condition contained in the mortgage indenture.  The mortgage trustee may withhold notice to bondholders of defaults (other than in payment of principal, interest or a sinking fund installment) if its responsible officers believe that the withholding of such notice is in the interest of the bondholders.
The holders of a majority in principal amount of the bonds outstanding may direct the mortgage trustee in the exercise of its powers and in either temporarythe case of a completed default may require the mortgage trustee to declare the maturity of the bonds accelerated, and upon certain conditions may rescind and annul such declaration.  The mortgage trustee may decline to follow any direction as to the exercise of its powers if the mortgage trustee (i) is advised by counsel that the directed action may not lawfully be taken or permanent form.(ii) determines in good faith that compliance with the directions would involve the mortgage trustee in personal liability or that it will not be sufficiently indemnified for any expenditures arising from compliance with the directions.
Evidence of Compliance with Indenture Provisions:  The specificmortgage indenture does not require us to furnish periodic evidence to the mortgage trustee as to absence of defaults or as to general compliance with the terms of the depository arrangementmortgage indenture; however, each time we request the mortgage trustee to take any action, such as the issuance of additional bonds or the release of cash or property under the mortgage indenture, we are required to deliver to the mortgage trustee certain certificates signed and verified by officers, engineers, accountants or other experts, who in certain cases are required to be independent persons.  Under pertinent circumstances these certificates certify as to absence of default, the fair value of property in respect of which the action is requested and our net earnings, and in all cases certificates or opinions are required as to our compliance with respectconditions precedent to a series of preferred stock or depositary shares representing such series of preferred stock that differ from the terms described herein will be described in the applicable prospectus supplement.action.

Item 17.                      Undertakings.
 
a.  The undersigned registrant hereby undertakes:
 
(1) to file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:
 
(i)to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;
 
(ii)  to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement.
 
(iii) to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;
 
provided, however, that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) of this section do not apply if the registration statement is on Form S-3 or Form F-3 and the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.
 
(2) that, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at the time shall be deemed to be the initial bona fide offering thereof.
 
(3) to remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
 
(4) that, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:
 
(i) Each prospectus filed by a registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and
 
II - 2
 

 
 
(ii) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5) or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii) or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus.  As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which the prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.  Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.
 
(5) That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:
 
(i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;
 
(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;
 
(iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and
 
(iv) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.
 
b.  The undersigned registrant hereby undertakes, that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in this registration statement shall be deemed to be a new registration statement relating to the securities offered herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
 
c.  The undersigned registrant hereby undertakes to file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of Section 310 of the Trust Indenture Act in accordance with the rules and regulations prescribed by the Commission under Section 305(b)(2) of the Trust Indenture Act.
d.  Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and
II - 3

Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable.  In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless
II - 3

in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
