WHEREAS, Lender and Harris Trust and Savings Bank ("Harris") are parties to a Custody Agreement dated , 1995 (the "Custody Agreement") pursuant to which Harris is acting as custodian (in such capacity, the "Custodian"); WHEREAS, pursuant to the Securities Lending Customer Agreement Custody Account, dated , 1995 (the "Customer Agreement"), between Lender, Custodian and Harris, Harris may lend securities held in the custody account established pursuant to the Custody Agreement to borrowers pursuant to borrower loan agreements in the form attached to the Customer Agreement; WHEREAS, Borrower and Harris are parties to a Borrowing Agreement, dated , 1995 (the "Borrowing Agreement"), pursuant to which the Borrower may borrow securities from Harris, including, without limitation, the Common Shares, par value $1.00 per share, of United States Cellular Corporation, a Delaware corporation ("USM") (including any other shares of capital stock of USM, into which such Common Shares shall be reclassified or changed, the "USM Common Shares"), held in the custody account (the "Custody Account") established under the Custody Agreement. NOW THEREFORE, in consideration of the premises and of the mutual covenants herein contained, Borrower and Lender hereby agree as follows: 1. LOANS OF SECURITIES. 1.1. Subject to the terms and conditions of the Borrowing Agreement, Borrower may, from time to time, initiate a transaction whereby Borrower seeks to borrow USM Common Shares held in the Custody Account from Harris. So long as the total number of USM Common Shares so borrowed by Borrower from Harris under the Borrowing Agreement and not yet returned thereunder would not, after giving effect to any request (a "Request") by Borrower that Harris make a Loan, be greater than the amount permitted in accordance with Schedule A hereto and Borrower is not in default under the Borrowing Agreement or this Agreement, such Request shall be a valid request for a Loan under the Borrowing Agreement. A Loan under the Borrowing Agreement shall not occur until the Loaned Securities are delivered by Harris to Borrower in accordance with the Borrowing Agreement. It shall be a condition to the obligations of Lender to make USM Common Shares available for borrowing by Borrower from Harris under the Borrowing Agreement, that Borrower shall have delivered the Collateral to Harris as required by the Borrowing Agreement. The terms "Business Day", "Collateral", "Loan", and "Loaned Securities", and certain other terms are defined below. 1.2. Notwithstanding anything to the contrary herein or in the Borrowing Agreement, the Custody Agreement or the Customer Agreement, Lender and Borrower agree that Lender will not make USM Common Shares available through the Custody Account to be loaned by Harris to Borrower and Borrower will not borrow USM Common Shares held in the Custody Account from Harris pursuant to the Borrowing Agreement or otherwise, if Lender shall have orally notified Custodian and Borrower that no USM Common Shares held in the Custody Account and that do not constitute Loaned Securities may then be loaned by Harris or borrowed by Borrower from Harris pursuant to the Borrowing Agreement. Any such notice shall be confirmed in writing (including by facsimile transmission) to Custodian and to Borrower by the end of the Business Day following the date of 2 such notice. Lender may provide any such notice at its sole discretion, at any time or times and for any reason. Lender shall not inform Custodian or Borrower in any such notice or otherwise (x) of the reason why USM Common Shares may not then be loaned by Harris or borrowed by Borrower from Harris pursuant to the Borrowing Agreement or (y) of the subsection of Section 1 of this Agreement pursuant to which such notice is being given. Any such notice shall (i) apply to all or any specified portion (provided that such portion shall result in a whole number of USM Common Shares then being able to be loaned by Harris and borrowed by Borrower from Harris under the Borrowing Agreement) of the USM Common Shares that do not constitute Loaned Securities at the time of receipt of such notice by Custodian and Borrower and (ii) be in effect until the receipt by Custodian and Borrower of the notice provided for in Section 1.4 hereof. 1.3. Notwithstanding anything to the contrary herein or in the Borrowing Agreement, the Custody Agreement or the Customer Agreement, if (i) USM shall have notified Lender of the occurrence of any of the events specified in Section 2(k)(i) of the Registration Rights Agreement, dated as of ____________ __, 1995, by and between Borrower, USM and Lender (the "Registration Rights Agreement") or (ii) Lender is otherwise aware of the occurrence of any such event (which in the case of the event described in Section 2(k)(i)(c) of the Registration Rights Agreement, shall mean, for purposes of this Section 1.3(ii), that USM or Lender, on the advice of its respective counsel, reasonably concludes that it is inadvisable as a matter of federal securities law that the Prospectus (as defined in the Registration Rights Agreement) continue to be used), Lender shall in any such case (unless a notice from Lender pursuant to Section 1.2 (relating to all of the USM Common Shares that do not constitute Loaned Securities) or this Section 1.3 is already then in effect) promptly orally notify Custodian and Borrower that no USM Common Shares that do not constitute Loaned Securities are then available through the Custody Account to be loaned by Harris or borrowed by Borrower from Harris pursuant to the Borrowing Agreement or otherwise. Lender shall confirm any such notice in writing (including by facsimile transmission) to Custodian and to Borrower by the end of the Business Day following the date of such notice. Lender shall not inform Custodian or Borrower in any such notice or otherwise (x) of the reason why USM Common Shares held in the Custody Account may not then be loaned by Harris or borrowed by Borrower from Harris pursuant to the Borrowing Agreement or (y) of the subsection of Section 1 of this Agreement pursuant to which such notice is being given. Any such notice shall (i) apply to all (but not less than all) of the USM Common Shares that do not constitute Loaned Securities and (ii) be in effect until the receipt by Custodian 3 and Borrower of the notice provided for in Section 1.4 hereof. 1.4. If (i) Lender shall have notified Custodian and Borrower in accordance with Section 1.2 or 1.3 that all or any specified portion of USM Common Shares are not then available through the Custody Account to be loaned by Harris or borrowed by Borrower from Harris pursuant to the Borrowing Agreement or otherwise and (ii) none of the events requiring a notice provided for in Section 1.3 hereof is then continuing, Harris may resume the lending of USM Common Shares held in the Custody Account and Borrower may resume the borrowing of such USM Common Shares from Harris pursuant to the Borrowing Agreement at any time after Lender orally notifies Custodian and Borrower of the resumption of the availability of USM Common Shares through the Custody Account for lending by Harris to Borrower and Lender shall confirm any such notice in writing (including by facsimile transmission) to Custodian and to Borrower by the end of the Business Day following the date of such notice. 1.5. Notwithstanding anything to the contrary herein or in the Borrowing Agreement, the Custody Agreement or the Customer Agreement, any notice provided for in Section 1.2 or 1.3 hereof shall advise Harris not to deliver any USM Common Shares from the Custody Account as Loaned Securities to Borrower under the Borrowing Agreement pursuant to any Request until the receipt by Harris of a Request subsequent to Custodian receiving a notice provided for in Section 1.4 hereof. 1.6. Notwithstanding anything to the contrary herein or in the Borrowing Agreement, the Custody Agreement or the Customer Agreement, if Borrower shall make a Request at a time when any USM Common Shares subject to such Request are not then available through the Custody Account to be loaned by Harris or borrowed by Borrower from Harris under the Borrowing Agreement or otherwise because Lender has given the notice specified in Section 1.2 or 1.3 hereof that all or a specified portion of USM Common Shares are not then available through the Custody Account to be loaned by Harris or borrowed by Borrower from Harris under the Borrowing Agreement, Lender shall notify Custodian not to deliver any USM Common Shares that are subject to such notice specified in Section 1.2 or 1.3 hereof pursuant to the Borrowing Agreement and Lender shall orally notify Borrower on the date of such Request that all or such specified portion of USM Common Shares are not then available through the Custody Account to be loaned by Harris or borrowed by Borrower from Harris under the Borrowing Agreement. Lender shall confirm such notice in writing (including by facsimile transmission) to Custodian and Borrower by the end of the Business Day following the date of such Request. 4 1.7. Upon receipt by Borrower of a notice provided for in Section 1.2 (provided that such notice relates to all (but not less than all) of the USM Common Shares that do not constitute Loaned Securities) or 1.3 hereof, Borrower shall not (i) offer, sell or deliver in settlement of any trade any Loaned Security if such offer, sale or delivery requires, in the reasonable opinion of Borrower's counsel, delivery (including constructive delivery (a "Constructive Prospectus Delivery") pursuant to Rule 153, or any successor or similar rule or regulation under the Securities Act of 1933, as amended (the "Act")) of the Prospectus (as defined in the Registration Rights Agreement) pursuant to the Act or the rules or regulations thereunder or (ii) deliver any Loaned Security in connection with a Common Share Delivery Arrangement (as defined in the Indenture, dated as of __________, 1995, between USM and Harris, as trustee, relating to USM's Liquid Yield Option Notes due 2015 (the "Indenture")) pursuant to the Common Share Delivery Arrangement Agreement, dated as of ________, 1995, between USM, Borrower and Harris, as conversion agent under the Indenture (the "Common Share Delivery Arrangement Agreement"), if such delivery requires, in the reasonable opinion of Borrower's counsel, delivery of the Prospectus (as defined in the Registration Rights Agreement) pursuant to the Act or the rules or regulations thereunder, in each case until the receipt by Borrower of a notice provided for in Section 1.4 hereof. 1.8. WITHOUT WAIVING ANY RIGHTS GIVEN TO LENDER HEREUNDER, IT IS UNDERSTOOD AND AGREED THAT THE PROVISIONS OF THE SECURITIES INVESTOR PROTECTION ACT OF 1970 MAY NOT PROTECT LENDER WITH RESPECT TO LOANED SECURITIES HEREUNDER AND THAT, THEREFORE, THE COLLATERAL DELIVERED TO HARRIS UNDER THE BORROWING AGREEMENT MAY CONSTITUTE THE ONLY SOURCE OF SATISFACTION OF BORROWER'S OBLIGATIONS IN THE EVENT BORROWER FAILS TO RETURN THE LOANED SECURITIES. 2. FEES FOR LOANS. Borrower shall pay Harris a monthly fee in arrears for Loans, such fee to equal 20 basis points, on a per annum basis, of the average daily market value of all Loaned Securities (as calculated pursuant to Section 2 of the Borrowing Agreement) outstanding during such month, which fee shall be the sole amount of compensation payable by Borrower to Harris or Lender for borrowing USM Common Shares pursuant to the Borrowing Agreement and this Agreement. Borrower shall provide Lender and Custodian with a written confirmation of such basis of compensation and the calculation thereof. Any fee payable hereunder shall be payable by Borrower to Harris (i) within 10 days of the end of the month for which the fee was incurred, or (ii) immediately, in the event of a default hereunder or under the Borrowing Agreement by Borrower. 3. TERMINATION OF THE LOAN. Unless otherwise agreed and subject to the terms of the Borrowing Agreement, Borrower may terminate a Loan of Loaned Securities under the Borrowing 5 Agreement in accordance with the terms of the Borrowing Agreement, and Lender may terminate a Loan made to Borrower pursuant to the Borrowing Agreement upon three Business Days' notice to Borrower. Lender shall exercise such right to terminate a Loan made to Borrower pursuant to the Borrowing Agreement (or to exercise any remedies for Borrower's failure to deliver such Loaned Securities or cause such Loaned Securities to be credited to Harris' account in accordance with the terms of the following sentence) by instructing Harris to terminate such Loan (or to exercise such remedies) in accordance with the terms of the Borrowing Agreement pursuant to the terms of the Securities Loan Termination Agreement dated as of _____, 1995 among Lender, Harris and Borrower (the "Securities Loan Termination Agreement.") Unless otherwise agreed and subject to the terms of the Borrowing Agreement, Borrower shall, on or before such termination date, deliver such Loaned Securities to Harris, or cause the Loaned Securities to be credited to Harris' account at a central depository clearing system; provided, however, that, notwithstanding anything to the contrary herein or in the Borrowing Agreement, Borrower's failure to so deliver the Loaned Securities or so cause the Loaned Securities to be so credited on or before such termination date shall not constitue a default hereunder or an Event of Default under the Borrowing Agreement, nor give rise to any of the remedies permitted pursuant to Section 8, 9 or 12 of the Borrowing Agreement, if such failure is caused by the Borrower's inability to acquire such Loaned Securities, in the reasonable opinion of counsel to Borrower, in compliance with applicable law, including, without limitation, Rule 10b-6 (or any sucessor or similar rule or regulation) under the Securities Exchange Act of 1934, as amended, unless such failure shall continue for a period of more than 10 days from the date of Harris' notice to Borrower terminating such Loan. In the circumstances described in the proviso in the preceding sentence, the Loan shall not terminate on the date called for in Harris' notice, but shall terminate on such later date upon which Borrower shall have delivered such Loaned Securities or caused such Loaned Securities to be credited to Harris' account as provided above. 4. RIGHTS OF BORROWER IN RESPECT OF THE LOANED SECURITIES. Until a Loan is terminated in accordance herewith and with the Borrowing Agreement, the Securities Loan Termination Agreement and the Customer Agreement and subject to the terms of the Borrowing Agreement, Borrower shall have all the incidents of ownership of the Loaned Securities, including, without limitation, the right to transfer the Loaned Securities to any purchaser (as defined in the New York Uniform Commercial Code) free of any adverse claim (as defined in Article 8 in the New York Uniform Commercial Code). Lender hereby waives the right to vote the Loaned Securities during the term of the Loan. 6 5. REPRESENTATIONS OF THE PARTIES HERETO.
