Health Gare Reform Excise Tax For Ni$ouroe, we examined the effect of the excise tax for all plans and groups combined {non-union and union), We examined the oosts separatety for single and marri*d retirees. For each of these coverage categorles, the pra" and post-65 promiums were blended based on headcounts. Thsexcise hxwas then edirnated by projectlng these premlums and comparing them to the projected *xcire tax ihresholds. The oxcess of premiums over the thresholds is subject to the excise tax, and the resulting 4G% excise tax, and a tax gross-up assuming a health plen tax rate of 35% was incorporated in the benefit obligation.

The premium$ werc projected using the health caro cost trend rate assumptlons as of December 3t, 2010" The excise tax thresholds were increased to the extent that health care cost trend rates oxceeded FS% for the period 2010 throug,h 2fl18. The total health car* cost trend raie ificrease from 2010 to 2018 waa SB,6%, so the st*tutory threoholds were increased 8.75% {1.fi$6/1.55) from $11,8S0 to $12,&86 lor single covCIrage and fram $30,950 to $33,S57 for manied covstErge tpre-6$). The post-65 thresholds were inrreased to $1 1 ,0$Z for *ingle *nd $?9,905 for married. The threshold thsn increaees with CPI+1 Yo ln 2019 and CFt for y+ars after 2019. For longterm annualCPl, we aesumed 3.S%,

Based on this methodology, there is no impact on the Ni$ourc,e plan liabilifi es,

Development ef S*if- lnsu red Premium €guiverlents projectians $epartte were perfoinred for pre- and post-65 plans, For each plan, 36 months of paid claim and enrollment data (January 2007 - December 2009) was used. The data was separated irrto three expeiience periods. For each experience period, paid claims were divided by enrollment, which was legged two months tc account the lag in claim payments. The per-employee cleims were then trended io 2010.

Finally, an adjustmentwae made to account for any plan design changes, and applicable adminlstralion feeswere then added to calculate the average self-insured premium equivalent lbr each plan,

The initial pre-65 claims costs for the purposes of the 2010 FA$ f 06 6xp61ss estimate were adjuSted for 1?/31/2010 disclosure due to an under-reporiing of prescription (Rx) drug claims data by Wagreons. This $djustment incorponated conected Rx drug data and is included in tire overal{ 12131/2010 actuarlat gains snd lssses.

Acljusil'nents t* Fully-lnsured Premiurn For pre'66 participants, the fully-lnsured pr€mium applies to activs employees and retirees. So for each plan, thn hue retiree co$k were developed using the active and retirse enrollment and age distributions and a 3% per year age gtading msumption. For post-65 partlcipants, this adjustmentwas not required.

The self4$surod premium equivalents wers then enrollment weighted with the adjusted fully-insured premium to develop ffte average per capita claims cast. The annual amounts for t010 are as follows based on afl average pre-6$ age of60 and an everage post-05ago ofZ4:

Hoalth Care Reform Exclse Tax For Ni$aurce, we examined the effect of the exciee tax for all plans and groups combined (non-union and union). We oxamined the costs separately for single snd married retireee. For each of these coverage catogories, the pre- and post-65 premiums were blended based on headcounts. Tho exClbe tax'was then esflmated by projacting these premlums and comparing them to the proJected excise taxthresholds. The exc6$s of promlums over the thresholds is suhject to the excise tax, and the resulting 40% exeise ta><, and a tax gross-up assuming a health plan tax raie of 35% wa$ incorporated in the benefit obligation.

The premium$ were projecied uslng the health care co*t trend rate assumptions as of December il, 2010, The excise tax thresholds were increasgd to the extent that health care cost trend rates exceeded Sg% for the period 2010 through 2018. The iotat health care cost trend rate lncnease from 2010 to 2018 was 68.6%, *c the statutory ihresho,lds were increased S.7S9o (1.$8$/1.58) fram $1 1,850 to $12,88S for *lngle coverage and from $80,950 to $33,657 for maried csverags {pra"S5). The post-S5 tlrresholds were increased tq S1il,0g2 for eingle and $29,905 for marisd. The throshsld then innr,eases with CPI+ 1 910 in 2019 and GPI for years after ?01 g. For long- term annualCPl, we asgumed 3,So/0.

Eased on this msthodotogy, there l$ no impact on the Nl$ourse plan Ilabillties.

Response: a. Attachment No.t, Summary of Affiliate Charge Agreements Schedule provides a list of the various contracts and Attachments A through FF affiliate contain the contract copies. b. The contracts describe the nature of the services provided to Columbia of Pennsylvania (CPA). The largest supplier of services, NiSource Corporate Services Company (NCSC), has service descriptions in Appendix A of Attachment H (NCSC Service Agreement).

The nature of services provided is also defined by the FERC account descriptions in Attachments z and 3. Exhibit No. 4 Schedule No. rr Page z of3 Witness: J. T. Gore

c. The contracts describe the basis on which charges are made to CPA. Appendix A of Attachment H (NCSC Service Agreement) supplies descriptions of the bases used to allocate NCSC charges.

The primary method for billing any affiliate is "direct charge." Under this method, all labor, materials and related expenses for the benefit of a specific affiliate are billed, as incurred, directly to the affiliate; therefore, no allocations are used. An allocated charge is a charge that occurs for the benefit of two or more affiliates who share the cost in accordance with an allocation basis. Guidelines have long been established which indicate that labor time and expenses should be charged directly to the affiliate receiving the benefits. In accordance with corporate guidelines, allocations are used only when direct charging is impractical.

When it is impractical to charge an affiliate directly for services provided, allocation bases are utilized. Each budget sponsor determines the appropriate allocation bases for the services they provide. d. Provided in Table zz(d) below are the allocation bases used to allocate costs to CPA by NCSC. Appendix A of Attachment H supplies detailed descriptions of these bases. Charges labeled "Direct Billed" relate to services rendered directly to CPA as outlined in Article 3.r in the NCSC Service Agreement in Attachment H. "NCSC Overheads" are costs related to maintaining NCSC as outlined in Article 3.3 and 3.S in the NCSC Service Agreement in Attachment H. With respect to charges from other affiliates, allocation factors are used as discussed in response c. above.

D ear S ecretary McNulty:

Enclosed for filing are an original and tbree copies of a verified summary of an affiliated interest arrangement befween Columbia Gas of Pernsylya64 lrc. and several aff,liated companies. This arrangement is submitted for the Commission's review rmd approval under Section 2102 of the Public Utility Code (66 Pa. C, S. $ 2102).

This document reflects a long-standing arrangement under which Columbia Gas of Pennsylvania has obtained various goods and sewices from its sister companies. The arrangement has been filed with the Commission in past rate proceedings, and Columbia believes that it was approved by the Commission at one time. The Company has not, however, been able to locate a Commission order approving this arrangement and therefore files it for approval at tbis time in order to remove any uncertaiary. lf you have any questions, please contact me at (412) 572-7759 or Mark Kempic, Senior Attomey, at (4LZ) 572-7142.

Dear Secretary Alford:

Enciosed, to: filing, are two (2) intenelated contracts between Columbia Gas of Pennsylvania, inc. ("CPA") arid Columbia Gas Transmission Corporation ("TCO"). The first contract, attached as Appendix "A", provides for the sale to TCO of certain undeveloped land owned by CPA in the Somerset County Industrial Park in Somerset Township, Pen-nsylvania. The second contract, aftached as Appendix "8", is a lease between TCO as Lessor and CPA as Lessee. The lease is for a service center to be constructed by TCO on the Somerset Counfy Induskial Park site. The purpose of the contracts is explained below.

Columbia has concluded that it should open a new service center in Somerset Township, Somerset County. The service center will house maintenance vehicles, wiil store inventory, and will sewe as the work site for a number of CPA employees. In anticipation of the futue need for this new service center, CPA, in 1994, purchased a tract of land in the Somerset County Industrial Park.

As part of the process of planning for the new service center, CPA examined whether to construct and own the service center or whether to lease a service center that was constructed to Columbia's specifications. Several proposals were considered with respect to the lease option, including a proposal from TCO. After reviewing the alternatives, it was decided that leasiag a service center to be built by TCO wouid be the most appropriate option. The contracts are required to implement this decision. "::::,

The first agreement, is a Release Agreement concerning a lease between TCO and CPA. The lease pertains to a buriding located in Somerset Township, Somerset County, Pennsylvania that CPA is currently leasing from TCO. CPA utilizes the building as a service center which houses maintenance vehicies, stores inventory and serves as a work site for some of CPA's employees. The second agreement, provides for the sale of the Somerset Service Center to CPA. As stated above, the service center is currently owned byTCO. The purpose of these agreements is explained below.

CPA has determined that it shouid purchase, rather than iease, the Somerset Service Center from TCO so that it can exercise fuil controi over the facllity. Owning the faciiity provides CPA with the abilityto lease the entire buiiding, lease portions ofit, or even sell the property. Purchasing the Somerset Service Center will also provide cost savings to CPA; specifically, this transaction will result in at least a $130,032.00 decrease in CPA's annual O & M. From a budgetary perspective, CPA has sufficient resources its 2000 capital expenditure program to pay for this purchase. CPA is purchasing the Somerset Service Center property at its current net book value of$'744,574.4I

Because both companies are prepared and desire to book this sales ffansaction to their respective 2000 budgets, CPA respectfully requests that the Commission issue its order

Re: Columbia Gas of Pennsylvania, Inc. - Affiliate Transaction Docket No. G-0004{067

Dear Mr. McNulty:

Enclosed for filing pursuant to 66 Pa. C.S.A 52102, are the original and three copies of Service Agreement between NiSource Corporate Services Company and Columbia Gas of Pennsylvania, Inc. ("Service Agreement"). As discussed below, this filing amends a recent filing made in the above-stated docket.

On June 14,2004, Columbia Gas of Pennsylvania, Inc. filed with the Public Utility Commission ("Commission") a "Service Agreement between NiSource Corporate Services Company and Columbia Gas of Pennsylvania, Inc." ("CPA'). CPA provided responses to the Commission's data requests on August 2,2004 and the Comrnission subsequently approved the Service Agreement on August 26,2004.

In the transmittal letter to the June filing and in CPA's response to the Commission's data request (response number FUS-9), CPA noted that the Service Agreement shall be executed upon approval by the Pennsylvania Public Utility Commission as well as upon receipt of any other necessary regulatory approvals. Since the time of the Commission's approval, the Securities and Exchange Commission notified NiSource Inc., the corporate parent of Nisource Corporate Services Company and Columbia Gas of Pennsylvania, Inc., that ii desired some changes to the language contained in the Appendix to the Service Agreement. The changes have been made to the Service Agreement and CPA is submitting the modified Service Agreement for approval by the Pennsylvania Public Utility Commission.

For your convenience, in addition to the modified version of the Service Agreement, I have included copies of a redline version which compares the new Service Agreement to Exhibit No. 4

Schedule No. 1 1 Attachment G-2 Page 2 of 17 Wtness: J. T. Gore

the one filed on June 14,2004. As stated in the June filing, the Service Agreement will enable NiSource Corporate Services Company to provide certain services to CPA and provides that said services shall be billed to CPA at cost in accordance with methods approved by the Securities and Exchange Commission. This is true for the modified Service Agreement as well. This modified Service Agreement replaces the existing "Service Agreement between Columbia Gas System Service Corporation and Columbia Gas of Pennsylvania, Inc." that was previously reviewed by the Pennsylvania Public Utility Commission in Case Number 943001.

The Service Agreement shall be executed upon approval by the Pennsylvania Public Utility Commission as well as upon receipt of any other necessary approvals. I have included an eltra copy of the Service agreement and the redline version. Please date stamp it and return them to me in the enclosed envelope. As always, if you have any questions please call me a|724.416.6328 or e-mail me at [email protected].

If so, what alternatives to the affiliate were considered, what criteria were used in conducting the comparison, and why was the affiliate selected? The agreement between Columbia Gas of Pennsylvania (cPA) and Colurnbia Gas Transmission Corporation (CGT) was not conpetitively bid. CGT developed the Blackhawk storage field and built the compressor station. It is very sinil"ar in design and configiuration to other storage fields and compressor stations built by cct, giving cGT considerable expertise and experience in the operation of such facilities. The ceT personnel vho operate and rnaintain the Blackhawk Storage Field are very faniliar with its operation and the idiosyncrasies of the various components of the fie1d, e.g. the wellheads, drips, brine disposal we1l, compressors'' detrydration, reg-ulation and measurement facilities. CGT personnel are readily available to operate the field on short notice, i.e., inject or withdraw gas as directed. by CPA, and to respond to emergency situations. A third party operator nould. have to becorne familiar wittr the individual operating characteristics of the field, a process which can be l-engtby

OSA RE-2 Witb regards to the gas transportation agreements what alternatives to the affiliate were considered, wbat criteria were used in conducting the conparison, and why was the affiLiate selected?

The transportation agreements which were subnitted were a direct resu'l t of the conversion of existing long-te::m agreements with CGT and Colunbia Gulf Transmission (culf) pursuant to the inplenentation of the FERC Order 536 restructuring of se:rrice options on CGT and Gulf. Implenentation of Order 636 took effect on CGT and GuIf on Novenber 7, 1993 . The ter:ms and conditions of these agreements, Iike the agreements they replaced., are subject to FERC jurisdiction. The realignment of service options pursuant to Order 636 did not provide CPA with an opportunity to voluntarily negotiate individually tailored agreements and therefore, CPA did not request competing se:rrice proposals from other interstate pipelines. To continue to serve its narkets, cPA, to the extent possible, needed to preserve under Order 536 the daily and seasonal capacity which it previously had under contract with ccT. In addition, CGT's physical proxinity to CPA's markets meant that CGT would remain a major transporter for CPA well into the foreseeable future. Since CPA had the reguired leveJ- of capacity under contract with CGT until the year 2oo4, the interests of CPA's customers were best served by CPA atteropting to preserve the pre-order 636 level of capacity and actively participating in the order 535 restructuring process. As a result of its active participation in the restructuring process, CPA has reduced its total contractual com:nitment witl its affiliates but essential.J-y preserved its Exhibit No. 4

total capacity holdings. The CGT total firn contract level was red.uced as a result of the direct city gate assignnent by CGT to CPA of 22,5OO dthrzday of capacity on Tennessee Gas Pipeline and of L9,753 dthrrday of transportation capacity on Texas Eastern. As a result of these assignnents, CPA now is directly connected to these unaffiliated pipelines. CPA's total finn transportation capacity on Gulf, however, was reduced by 48,308 dth/day through the reassignment of that capacity amoDg a nunber of LDCs through the restructuring process. The results. of CGT,s restructuring, and the associated effect on cPA, were reviewed in CPA's 1993 51307 (f) proceeding.

OSA RE-3 Explain aII revenue and ratemaking inplications that the affiliated interest agreenent may have,

There are no revenue iroplications associated with the transportation or operating and naintenance agreenents. These . , agreements have gas cost expense irnplications, which were . reviewed in the context of CPA's 1993 S1307(f) proceeding and wiLl be subject to review again in its tgs+ S1307(f) filing.

OSA REJ4 Piovide an explanation as to why the gas transportation agreeroents were filed with this Commission over tlro months after their effective date of November 1, 1993.

As indicated in response to Question OSA RE-2, the effective date of the agreements tras dictated. by the inplenentation of Order 636 rnandated changes on CGT and culf, which changes remain subject to revien on appeal. The delayed filing was a result of administrative oversight arising from the fact that the subnitted contracts merely continued existing long-term contractual rel-ationships.

Yes. Exhibit No. 4

Re: Columbia Gas of Pennsylvania, Inc. Affi liated Interest Filing DocketNo. G-

Dear Acting Secretary McNulty:

Enclosed, for filing pursuant to Section 2102 of thepublic utility code, 66 pa.c.S. g2102, is a Master License Agreement between columbia Gas of pennsylvaniq Inc. (,,Columbia'; ana CNS Microwave, Inc. ("CNS'), an Exempt Telecommunications Company.

The Telecommunications Act of 1996 amended the Public Utility Holding Company Act of 1935 ("PUHCA') by adding a new Section 34 thatallows registered holding companies to establish "Exempt Telecommunications Companies." These Exempt Telecommunications companies, or ETCs, are special purpose subsidiaries that provide comrnercial telecommunications, infonnatlon and related products and services to the public. ETC status is determined by the Federal Communications Commission. Section 34(i) piovides that a public utility may contract for services or goods with an affiliated ETC only if the contract is approved by the state commission having jurisdiction over the rates of the public utility. In addition, Section 34(i) provides that the state commission can elect to waive its authority under Section 34(i). Thus, Columbia requests that the Commission approve the attached Master License Agreement or, in the alternative, issue a notice waiving its authority und.er Section 34(i) of PtlHCA.

Preparation and_Filing of Tax Returnsl Allocation of Taxes

Section 2.l Federal Rehrns.

(a) A U.S. consolidated federal income tax retum shall be prepared and filed by NiSource for each taxable year in respect of which this Agreement is in effect and for which the Consolidated Group is required orpermitted to file a consolidated federal income tax return. NiSource and all its subsidiaries shall execute and file such consents, elections and other documents that may be required or appropriate for the proper filing of such retums.

(b) (i) The Consolidated Group rvill elect, on a timely basis, in accordance with Code Section 1552(b) and Section 1.1552-1(c)(2) of the Regulations to allocate its consolidated tax liability (other than altemative minimum tax ("AMT") and its related credits) among its Members under the method described in Sections 1.1502-33(d)(3) and 1,.1,552-l(a)Q) commencing with the consolidated taxable year ended December 31,200L. The fixed percentage to be used for purposes of Regulations section 1.1502-33(d)(3xi) is 100%. The general effect of such method is to first allocate the consolidatedtax liability among the Members of the Consolidated Group on the basis of the percentage of the total consolidated tax which the tax of such Member (other than AMT and its related credits) if computed on a separate return basis would bear to the total amount of the taxes (other than AMT and its related credits) for all Members of the group so computed. Then such method allocates an additional amount (the "Tax Benefit Amounf') to each Member up to, butnot greater than, the excess, if any, of its Exhibit No. 4 Schedule No. 11 Attachmenl N Page4of11 Witness: J. T. Gore

Separate Retum Ta"r liabilify (other than AMT and its related credits) over the amoirnt allocated to such Member in the previous sentence. The total of the Toc Benefit Amorurts allocated to Members shall result in payments to, and an increase in the eaffrings and profits of, the Members who had items of deduction, loss or credits to which such Ta:< Benefit Amount is attributable. This election is intended to comply with Rule a5(c)(5) under the Act, as modified by Section 2(d) below.

(ii) The allocation of the altemative minimum tax liability incuned by the NiSource Group and the resulting minimr.rm tax credit shall be allocated in the manner set forth in Proposed and Temporary Treasury Regulation Sections 1.1502-55. This method generally allocates (i) any AMT paid by the NiSource Group based on the relative separate adjusted AI\47 of each Member and (ii) the minimum tax credit (AI{TC) on the basis of the AMT previously assigned to such Member and assuming that AMTC is utilized on a "fust inlfirst out" methodology, and that to the extent that AMTC arising in one year is not fully utilized, such AMTC is utilized proportionately by the Members previously assigned AMT for that year.

(c) Each Member's allocable share of the consolidated income tax liability as determined in Section z.I(b) hereby shall be used in both (i) the determination of each Member's earnings and profits and (ii) determining the amounts to be paid (as provided in Section 3.4 of this Agreement) by Members to NiSource with respect to each Member's share of the Consolidated Group's Tax tiability and payrrents from NiSource to Members with respect to the use of a Member's tax atfributes.

(d) (i) The aggregate of all arnounts paid by Members of the Consolidated Group (the "Paying Members") as a result of the excess of each Members' Separate Return Tax liability (as detennined under Section 1.1552-1(a)(2XiD of the Regulations) over the amount allocated to such Member as its share of the Consolidated Tax Liability under Code Sectionl5l2 (i.e., the Tax Benefit Amount) shall be paid by NiSource to the other Members (the "Loss Members") which had tax deductions, losses and credits to which such payments by the Paymg Members are attributable. The apportionment of such payments among Loss Members shall be in a manner that reflects the Consolidated Group's absorption of such tax attributes in the manner described in Section z.I(e) below. The payments to the Loss Members for their tax attributes shall be pursuant to a consistent method which reasonably reflects such items of loss or credit (such consistency and reasonableness to be determined by the Designated Official).

(ii) Notwithstanding the provisions of section 2.1(d)(i), the Tax Benefit Amount allocated to NiSource and paid to NiSource as a result of its being a Loss Member shall be limited to its Tax Benefit Amount determined without regard to this section 2.l(bxii) multiplied by a fraction, the numerator of which is NiSource's interest deduction attributable to Acquisition Indebtedness, and the denominator of which is the sum of all of NiSource's deductions. The podion of NiSource's Tax Benefit Amount which cannot be allocated and paid to NiSource due to the operation of this Section shail be reallocated to Paying Members of the Consolidated Group otber than NiSource in accordance with the principles contained in section 2.l(bxi). Exhibit No. 4 Schedule No. 11 Attachment N Page5of11 Witness: J. T. Gore

(e) In apportioning the payments to Loss Members for the Tax Benefit Amount pursuant to Section 2.1(d) hereof:

(i) any consolidated net operating loss ("NOL') shall be allocated among the group Members pursuant to Regulations Section I.1502-21b). To the extent the consolidated NOL is carried back, any Member's individually allocable NOL shall be deemed carried back and utilized in proportion to the amount that the Member's NOL bears to the consolidated NOL. Analogous principles shall apply in the case of NOL carryforwards;

(ii) with respect to each type of credit used to offset all or a portion of the Consolidated Tax Liability otherwise payable, such credit shall be allocated a:nong the Members by crediting to each Member an amount of credit which that Member would have available to utilize on a separate retum basis in a manner consistent with the method set forth in Section 2. 1(eXi) above.

(iiD the cost of any credit recapture which results in the payment of tax shall be specifically allocated to the Member whose credit is recaptured determined in a manner consistent with the provisions of Section 2.1(e)(i) above.

(0 The allocation of tax shall be subject to firther adjustment from time to time on account of the payment of additional tax or the receipt of a refund attributable to either the filing of an amended return or on account of the results of an audit conducted by the Internal Revenue Service or other relevant taxing authority.

Section 2.2 Other Taxes. (a) NiSource will prepare and file (or cause to be prepared and filed) all returns of Other Ta:

(b) Each Member of the NiSource Group that does not file an Other Retum together with any other Member of the NiSource Group shall be solely responsible and obligated to pay the tax liability with respect to such return from its own funds. Such returns shall be prepared and filed by NiSource or the Member fi1ing the Other Retum.

(c) If any Member of the NiSource Group is required to file a combined, consolidated or unitary return for Other Taxes with another Member of the NiSource Group, but not with NiSource (an "Other Ta>res Subgroup"), then NiSource shall have the rights, powers and Exhibit No. 4 Schedule No. 11 Attachment N Page6of11 Witness: J. T. Gore obligations to file such tax retums and apportion among and, coilect and remit from, the applicable Members such Other To

The Eligible Borrowers from time to time have need to borow funds on a short- term basis. Some of the Parties from time to time are expected to have funds available to invest on a short-term (less than one year) basis. The Parties desire to establish a pool of funds (the "system Money Pool'), to be administered by the Administrative Agent (defined below), to coordinate such invesfrnents and bonowings in order to provide for certain of the short-term cash and working capital requirements of the Eligible Borrowers.

Now TrnrcnoRE, in consideration of the premises and the mutual promises set forth in this Agreement, the Parties agree as follows:

Anrrclnl INvnsrunNTS AlrD Bonnowncs

Section 1.1. Investments in System Money Pool. Each Party will determine each day, on the basis of relevant factors determined in such Party's sole discretion, the amourt of funds it has available to invest in the.System Money Pool, and will invbst such funds in the System Money Pool. The amount of each Parfy's investments in the System Money Pool shall be evidenced by the records of the Administrative Agent, which shall be conclusive and binding upon all Parties. Each Party may withdraw any of its invested funds from the System Money Pool at any time upon notice to the Administrative Agent.

Section 1.2 Rights to Borrow. All short-term borrowing needs of the Eligible Borrowers may be met by funds in the System Money Pool to the extent such funds are Exhibit No. 4 Schedule No. 11 Attachment O Page2 oI 14 -2- Witness: J. T. Gore available. Each Eligible Bonower shall have the right to make short-term bonowings from the System Money Pool (each a "loan" or a "borrowing") from time to time, subject to the availability of funds and the limitations and conditions set forth in this Agreement and in the applicable orders of the Securities and Exchange Commission ("SEC"). Each Eiigible Borrower may request loans from the System Money Pool from time to time dwing the period from the date of this Agreement until this Agreement is terrrinated by written agreement of the Parties; provided, that the aggregate amount of all loans requested by any Eligible Borrower under this Agreement shall not exceed the applicable borrowing limits set forth in applicable orders of the SEC and other regulatory authorities, resolutions of such Eligible Borrower's shareholders and Board of Directors, such Eligible Borrower's goveming corporate documents, and agreements binding upon such Eligible Borrower.

Gore r'"1 rn.f, P.:l'r- I Money Pool Petition <. .l 1t irt o Overview of NiSource Money Pool ,i i..- rc C-) €t '5 CJ lie 5 'cJ1 The NiSource, Inc. System Money Pool Agreement (the "Money Pool") is aFontraffial arrangement arnong NiSouce, lnc. and its subsidiary companies (the i'subsidiaries'fitogether, the "System"), approved by the Securities and Exchange Commission (the "Commission") pusuant to the Public Utility Holding Company Act of 1935, which pennits efficient short-term financing and investing by pooling temporary excess cash of the Subsidiaries and NiSource. As participants-in the Money Pool, Subsidiaries which have temporary excess cash ("Lenders') deposii such firrds in the Money Pool. Money Pool fi.rnds may be invested in a portfolio of high- q,rality short-term securities- or lent to other Subsidiaries ("Borrowers') on a short-tenn basis.. All companies in the Syg-tem participate in the Money Pool, although NiSource and certain of the , Subsidiaries participate only as Lenders, Each Subsidiary's'cash position and the resultant amounts of its deposits or required borrowings, if any, are determined and tracked individualiy, on adaily basis.

The Money Pool is administered by NiSource Corporate Services, Inc. Funds are -consolidated through bank accounts maintained by NiSo.urce Corporate Services, Inc. antl, to the 'extent thpt ttr" L'enders' deposits exceed the Borrowers' requirements, funds are invested in a portfolio'of high quaiity short-term secr.rities for the benefit qf the Lenders,

At any, time when the Borowers' requirements exceed the Lenders' temporary excess cash balances, NiSowce, through'its NiSource Finance Corp. subsidiary, borrows the required funds extemally and then deposits these funds into the Money Pool. At no time does NiSource, lnc. or NiSource Finance Corp. bonow from the Money Pool or from any Subsidiary.

The interest rate charged to Borrowers from the Money Pool and paid to Lenders for deposits to the Money Pool (the Money Pool Rate') is equal to the composite weighted avorage rate on ali NiSource Finance Corp. short-term borrowing transactions and-/or the Money Pool Invesfrnent rate. Therefore, during a given month, there could be any combination of NiSource Finance Corp. borrowings and invesfinents. The Money Pool Rate would be the composite of those tansactions. In this manner,.Money Pool Lenders receive an atfactive relutn on their temporary excess cash investments, and Borrowers are charged a cost-effective interest rate on theirbonowings.

NiSource temporary-of excess funds and Money Pool funds to the extent that such funds exceed the requirements the Borrowers, are invested in accordange with Short-Term Invesftnent G-uidelines (the "Guidelines") approved !y ttre NiSource Chief Financial Officer.

When there are both Lenders (including NiSource) and Borrowers in the Money Pool ai the same time, funds of each Lender are allocated pro rata to each Borrower. A11 borrowings and deposits through the Money Pool are documented in the records of the individual participants. Exhibi!No: 4 Schedule No. 11 Attachment O Page 12 ot 14 Witness: J. T. Gore

Currently, the borrowing and investment positions of all Coiumbia money pool participants are consolidated or pooled into one money pool netting account held at PNC Bank in the name of Columbia Energy Group Service Corp. Once the required regulatory approvals are secured to expand the Columbia Money Pool to incorporate "old NiSowce" subsidiaries, this netting account will reside within NiSource Corporate Seruices. The borrowing and investment positions of all Money Pool parficipants will then consolidated into the NiSource Corporate Services netting account. Exhibit No. 4 Schedule No. 11 Attachment O Page 13 of 14 Witness: J. T. Gore o Benefits of NiSource/Columbia Monev Pool - Enterprise-wide pooling of cash balances to reduce external borrowings. This improves credit ratios and reduces bonowing costs for all NiSource entities.

- Creates an Internal bank for subsidiaries. This reduces administrative costs and achieves a lower cost of funds for all NiSowce entities.

- Reduced extemal borrowings resulting from money pool utilization represents a net cost savings versus maintaining investnent balances at the subsidiary level.

'Money pooi automates funds flow tbroughout the'enter enterprise by upstreaming all cash balances via zero balance bank accounts.

- Money pool system automates accounting entry generation via Treasury Workstation platform.

- Money pool system is flexible and scalable.

Money pool interest rates advantageous to both lenders and borrowers.

Intereompany financing (short-term) among virtuatly all of NiSowce's subsidiarieb would be facilitated by one mechanism - the money pool. Extemal financing activity in o the commercial paper and bank ciedit market is conducted by only one entity - NiSow:e tirnance uorp.

Enterprise-wide cash concentration and cash manAgement is optimized, as the entire enterprise's daily cash position flows upstrea:n into the money pool. Daily borrowing decision, and therefore prieing, is optimized at the money pool or parent level'

- Intercompany transactions among money pool.participants are settled via "book entry,'? clearing against the money pool account. Intercompany movement of cash is therefore no longer necessary. Transactional cost savings result-

Money pool system withinResource I.Q. captures all cash and non-cash VC transactions, and creates a "daily operations report" that the respective accounting deparhrents can book to the generai ledger. Exhibit No. 4 Schedule No. 11 Attachment O Page 14 of 14 Witness: J. T. Gore

Financial Benefits from Money Pool Utilization

The Money Pool strcture generally eliminates excess cash balances and external short- term investments at the subsidiary level. This is because excess cash balances of subsidiaries are pooled as Investments into the money pool where sub.sidiaries needing to bonow firnds have access to these investment balances via the money pool. This has the beneficial effect of reducing extemal borrowings at the parent-holding company level.

. Since the parent company's incremental borrowing rate is invariably higher than investrnent rates for either the parent cjr its subsidiaries, interest cost savings from the reduced level of external borrowings more than offsets forgone investment income at the subsidiary level. For example, the average borrowing rate for the Columbia Energy Group Money Pool during caiendar 2000 was 6.84yo, while the average inveshnent rate was 5.78%. Appiytng this interest rate differential to the current investment balances in the CEG money'pool ($275,869,793) results in an annualized interest cost savings (net of forgone interest income) of $2.9 million.

Response:

Description of Terms and Conditions

Columbia's lease agreements depicted on page 3 of this exhibit fall into the categories of office and service space rental, motor vehicle rental, general tools, and communication equipment. Because the terms vary by the nature and type of property leased, the following description highlights typical conditions which may be found in lease agreements for that specific type of lease property. Of course, even within categories the specific terms and conditions are subject to variation from agreement to agreement.

Office and Service Space Rental

Each such agreement particularly describes the premises to be leased. Typically, the annual rental is due in equal monthly installments payable on the first day of the month. The lessee specifically agrees to use the demised premises for ofiice and commercial purposes only without express written consent of the lessor to use the building for other purposes. It is the lessee's responsibility to pay all real estate taxes and assessments levied against the demised premises during the term of the lease. The lessee further agrees to purchase public liability insurance during the lease term. The assignment or subletting of the demised premises is subject to the written consent of the lessor, which consent is to be reasonably granted. The lessee agrees to indemnift the lessor against liability for damages including attorneys'fees occasioned by damage or losses to the lessee, its employees or third persons resulting from any causes except the negligence of the lessor. It is the responsibility of the lessor to maintain the roof and exterior structural walls and sewage system of the demised premises in good condition. It is the responsibility of the lessee to maintain the interior of the building, ordinary wear and tear excepted. The lessee is permitted to make improvements and alterations to the premises in a workmanlike manner, without impairing the structural soundness of the existing building or improvements. These lease agreements typically contain a covenant on the part of the lessor permitting the lessee the quiet enjoyment of the demised premises without disturbance during the lease term. Exhibit No. 4 Schedule No. rz Page z of3 Witness: J. T. Gore

Motor Vehicle Leases/Licensed General Tool Lease

Columbia leases motor vehicles from Peterson, Howell, and Heather, Inc. The lease term commences on the date each unit is physically delivered to lessee. Upon the expiration of the initial term, the lessee may renewthe lease from month to month subject to termination upon 3o days written notice to the lessor. The rental payment is calculated on the basis of an equal monthly share of the base price over the life of the lease term plus a monthly lease service charge. Each unit is to be purchased at the best procurable market price, subject to the prior approval of the lessee. Upon surrender of a leased unit to the lessor, within 3o days the unit will be sold at the best price obtainable. If the sale price exceeds the unit's amortized value, lessee is entitled to the excess. If the sale price results in a deficiency below the amortized value, that deficiency is paid to the lessor by the lessee. Lessee is obligated to maintain and service each unit in good condition, ordinary wear and tear excepted.

Communication Equipment

Columbia Equipment consists of radio site leases and dedicated telephone line rentals.

Columbia leases radio sites for the location of radio transmitting equipment. These site leases generally include the right to install an antenna on an existing structure (water tower, commercial radio tower, etc.) and either the right to install the actual transmitting equipment in an existing communications building or the right to erect a small radio transmitter building near the base of the structure.

Columbia rents dedicated telephone lines from NiSource Corporate Services on a month to month basis. Exhibit No.4 Schedule No. 12 Page 3 of 3 Witness: J. T. Gore
