1 EXHIBIT 7 EXECUTION COPY THIRD AMENDED AND RESTATED AGREEMENT REGARDING GUARANTEE This Third Amended and Restated Agreement Regarding Guarantee (this "Agreement") is made by and among Motorola, Inc., a Delaware corporation ("Motorola"), Iridium LLC, a Delaware limited liability company ("Iridium"), and Iridium Operating LLC, a Delaware limited liability company and a wholly-owned subsidiary of Iridium ("Operating"), is dated as of December 23, 1998, and amends and restates the Second Amended and Restated Agreement Regarding Guarantee, dated as of May 11, 1998 (the "Second Amended Agreement Regarding Guarantee") among Motorola, Iridium and Operating, which amended and restated the Amended and Restated Agreement Regarding Guarantee, dated as of July 11, 1997 (the "First Amended Agreement Regarding Guarantee") between Motorola and Iridium, which amended and restated the Agreement Regarding guarantee originally dated as of August 21, 1996 (the "Original Agreement Regarding Guarantee") between Motorola and Iridium. In connection with, and as a condition to, entering this Agreement, Operating, Iridium and Motorola have entered into that certain Second Amended and Restated Memorandum of Understanding (the "MOU"), dated December 23, 1998. Motorola has entered into a Guarantee Agreement, dated as of August 21, 1996, as amended (the "Bridge Guarantee Agreement"), pursuant to which Motorola has guaranteed the payment of up to $275,000,000 of the obligations of Iridium under that certain Credit Agreement, dated as of August 21, 1996, as amended, between Operating (as successor to Iridium) and the Lenders named therein (the "Bridge Agreement"). The First Amended Agreement Regarding Guarantee and the Original Agreement Regarding Guarantee defined certain rights and obligations of the parties relating to such guarantee and possible additional guarantees by Motorola. Capitalized terms used and not otherwise defined herein shall have the meanings ascribed thereto in the Bridge Agreement. On December 18, 1997, following the date of the First Amended Agreement Regarding Guarantee, Iridium entered into an asset drop-down transaction (the "Asset Drop-Down Transaction") with Operating, pursuant to which substantially all of the assets and liabilities of Iridium were transferred to Operating. Operating has entered into a $1 billion senior secured interim Credit Agreement, dated as of December 19, 1997, with the banks and other financial institutions named therein (the "Secured Bank Facility"). Operating, Iridium and IWCL intend to raise new funds and engage in other transactions to finance Operating's development, construction and operation of the Iridium satellite communications system (the "Iridium System"), including the refinancing of Operating's indebtedness under the Secured Bank Facility. As set forth in 2 EXECUTION COPY the MOU, Motorola has conditionally agreed to provide certain additional support to the efforts of Operating and Iridium to obtain such financing, including the Guarantee Increase (as defined in the MOU), the Alternative Guarantee (as defined in the MOU), the $475 Million Guarantee Amendment (as defined in the MOU), the O&M Deferrals (as defined in the MOU) and the O&M Guarantee (as defined in the MOU). The purpose of this Agreement is to set forth certain binding agreements among Motorola, Iridium and Operating that are intended to (i) incorporate the remaining pertinent terms of the Second Amended Agreement Regarding Guarantee and (ii) reflect certain agreements of the parties in respect of the Guarantee Increase, the Alternative Guarantee, the $475 Million Guarantee Amendment, the O&M Deferrals and the O&M Guarantee. The parties agree as follows: 1. Handset Guarantee. (a) Motorola Agreement to Provide Handset Guarantee. If at any time and from time to time Operating becomes obligated to purchase hand-held phones or belt-worn pagers (collectively, "Subscriber Equipment") from Motorola pursuant to that certain Standby Purchase Agreement between Motorola and Operating (the "Handset Purchase Agreement"), Motorola hereby agrees, upon the written request of Operating, to provide a Guarantee relating to an aggregate of up to $175 million of Commitments (the "Handset Guarantee") under the Bridge Agreement or under a separate Credit Agreement having the terms identical in all material respects to the then current Bridge Agreement; provided, however, that Motorola shall not be required to agree to a Handset Guarantee to the extent that Motorola's liability under the Handset Guarantee would exceed $175 million (inclusive of principal, interest and other amounts). (b) Operating Agreements with Respect to Handset Guarantee. Operating hereby agrees that all funds borrowed that are subject to the Handset Guarantee ("Handset Borrowings") will be used exclusively for payments to Motorola under the Handset Purchase Agreement. Operating hereby agrees that, if Motorola provides the Handset Guarantee, to the extent of available funds that are subject to the Handset Guarantee, Operating shall borrow available funds under the Handset Guarantee and pay all amounts due under the Handset Purchase Agreement. -2- 3 EXECUTION COPY 2. Reimbursement Obligation. (a) Operating Default. Other than as set forth under Section 2(b) below, if and to the extent that any Lenders demand that Motorola pay, and Motorola does pay, any Guaranteed Amount pursuant to any Guarantee, Operating shall, promptly upon receipt from Motorola of a written demand for reimbursement, reimburse Motorola for such Guarantee Payment, plus interest accruing at a rate equal to that which would be in effect under the Credit Agreement relating to such Guaranteed Amount, without duplication; provided that this Section 2(a) shall not affect the obligations of Iridium and Operating to pay compensation pursuant to Section 3. (b) Motorola Default. If a Guarantee Payment is made in respect of a Guaranteed Amount that has been accelerated or otherwise become due as a result of a Motorola-Based Default, then (i) Motorola shall assume and become subject to the obligations of the Lenders under the applicable Credit Agreement vis-a-vis Operating (including, without limitation, the obligation to make loans in the aggregate principal amount of such Lenders' commitments under such Credit Agreement), (ii) Motorola shall assume and become entitled to the benefits of the rights of the Lenders under such Credit Agreement vis-a-vis Operating (including, without limitation, the right to receive payments in respect of loans made under such Credit Agreement, upon acceleration or otherwise), but not including any provisions relating to a Guarantee or any right or remedy arising as a result of the occurrence of a Motorola-Based Default, (iii) Operating shall become obligated to reimburse Motorola for such Guarantee Payment and to repay any additional amounts for which Operating may become indebted to Motorola pursuant to clause (ii) above on the terms and conditions contained in such Credit Agreement as such Credit Agreement is modified by clause (ii) above, and (iv) Operating shall continue to be subject to the terms and conditions of such Credit Agreement (including, without limitation, the covenants contained therein), as such Credit Agreement is modified by clause (ii) above, it being expressly understood that Motorola shall in such circumstances have the right to accelerate payments under and otherwise exercise its rights under any such Credit Agreement to the extent set forth therein as if it were a lender thereunder to the extent that such right to accelerate or other rights arise from some event or circumstance other than a Motorola-Based Default or a Guarantee. (c) Costs and Expenses. Operating further agrees to reimburse Motorola for all reasonable out-of-pocket costs and expenses (including, without limitation, the fees and expenses of legal counsel) in connection with any enforcement of Operating's obligations under Section 2(a) (including, without limitation, any fees and expenses incurred in connection with any bankruptcy proceedings). (d) Subordination.

Compensation to Motorola. (a) Warrant Compensation. Except as set forth in Sections 3 (e) and 3(f), Iridium shall compensate Motorola for incurring the Motorola Exposure by issuing warrants (the "Warrants") to purchase Class 1 Interests in Iridium ("Shares") to Motorola in the amounts specified in the table below.

In addition, in the event that Motorola earns Warrants with respect to periods beginning after March 1, 2001, at Motorola's election, Iridium shall compensate Motorola with Shares issued directly to Motorola in the amounts specified in the table below in lieu of Warrants. (b) Calculation of Warrant Compensation. Subject to Sections 3(e) and 3(f), Motorola shall earn Warrants or Shares based on the amount and duration of Motorola Exposure.

(c) Payments of Compensation Due Pursuant to This Agreement. Operating and Iridium hereby agree that they will pay, or cause to be paid, all compensation due to Motorola pursuant to this Agreement, including, without limitation, Warrants, Shares or IWCL Warrants due pursuant to Sections 3(a), 3(e) and 3(f) and cash due pursuant to Sections 3(e) and 3(f), quarterly (for the fiscal quarter of Motorola then ending) no later than 48 hours prior to the last day of each fiscal quarter of Motorola. (d) Warrants Issued to Date; No Further Limitations on Warrant Compensation. The parties acknowledge that Warrants for 7,741,346 Shares have been earned by Motorola as of December 15, 1998 with respect to outstanding Motorola Exposure (not including compensation earned pursuant to Section 3(e)). The parties agree that no limitation shall apply to compensation earned pursuant to this Section 3. (e) High Yield Equivalent Compensation. During any period in which each of the following conditions (the "High Yield Equivalent Conditions") exists: (i) the Motorola Exposure outstanding shall be $275,000,000 or less; (ii) no other person or party providing guarantees for the support of Iridium's indebtedness for borrowed money is receiving equity compensation from Iridium or IWCL in respect of such guarantees, (iii) no mandatory prepayment or redemption or acceleration of any Senior Notes (as defined in the MOU) has occurred (except as a result of Motorola's disposition of Class 1 Interests causing a "change in control" (as defined in the Offering Memorandum) to occur under the Senior Notes); and (iv) Iridium has complied with the terms of this Agreement and the MOU, then, at Iridium's option, in lieu of issuing Warrants or Shares pursuant to Sections 3(a) and 3(b). Iridium and Operating shall pay compensation to Motorola (the "High Yield Compensation") as follows: (1) Operating shall pay Motorola cash compensation for the Motorola Exposure, in an amount equal to (x) the average daily Motorola Exposure during any period for which the Motorola Exposure is greater than zero multiplied by the excess, if any, of (A) the weighted average daily interest rate applicable to the Series A Notes and Series B Senior Notes (13.625% / 360 = 0.0378472%) over (B) the weighted average daily interest rate actually charged by the Lenders under the Credit Agreements related to the Motorola Exposure for such period. -5- 6 EXECUTION COPY (2) Iridium shall issue to Motorola warrants ("IWCL Warrants") to purchase shares of Class A Common Stock of IWCL (the "Common Stock") in an amount equal to the average daily principal amount of Motorola Exposure during such period multiplied by the daily equivalent of the warrant compensation payable to the initial holders of the units comprised of warrants to purchase Common Stock and Series A Notes with respect to such amount (calculated on a pro rata daily basis from the date of the issuance of such Series A Notes to the stated maturity thereof, such amount being IWCL Warrants to purchase 66.758 shares of Common Stock per each full $100,000,000 of Motorola Exposure per day (calculated on a pro rata basis for the actual amount of Motorola Exposure outstanding)). IWCL Warrants issued pursuant to this paragraph (2) will have the same exercise price as the warrants issued with the Series A Notes ($20.90 per share of Common Stock, subject to anti-dilution adjustments) but all other terms of the IWCL Warrants and Common Stock will be as specified for Warrants and Shares, respectively, in Section 3(a) (the IWCL Warrants will provide for a ten year term, become exercisable on March 1, 2001 or upon receipt if issued after that date and be issued free of restrictions on transfer (other than restrictions imposed by applicable law)); provided, however, that, if Motorola's holdings of Common Stock, including Common Stock issuable upon exercise of IWCL Warrants or similar securities (but not including Common Stock issuable under the Interest Exchange Agreement), would cause the Iridium Bermuda Special Rights Period (as defined in the LLC Agreement) to terminate, Motorola will not be issued IWCL Warrants or Common Stock but instead will be issued Warrants or Shares (with substitution on a one-for-one basis, subject to the anti-dilution provisions of the Interest Exchange Agreement). A form of IWCL Warrant is attached hereto as Exhibit 2. Iridium hereby agrees to exercise its rights under the Share Issuance Agreement and to take all other necessary actions to cause IWCL to (i) reserve sufficient shares of Common Stock for issuance upon exercise of all outstanding IWCL Warrants and (ii) issue shares of Common Stock in respect of IWCL Warrants at the time or times such IWCL Warrants are duly exercised, and Iridium agrees not to agree to any amendment to the Share Issuance Agreement that would be reasonably likely to adversely affect Iridium's ability to perform its obligations hereunder. (3) In each case (1) and (2) multiplied by the number of days the Motorola Exposure is outstanding. (f) Limited Term Cash and IWCL Warrant Compensation for Certain Motorola Exposure. Prior to October 1, 1999, Motorola shall not be compensated pursuant to Section 3(a) or Section 3(e) for Motorola Exposure that results from the $475 Million Guarantee Amendment, the Handset Guarantee, the O&M Guarantee or the O&M Deferrals (collectively, the "New Exposure") but shall be compensated for such New Exposure as set forth in this Section 3(f). -6- 7 EXECUTION COPY (1) For all New Exposure relating to the $475 Million Guarantee Amendment, the Handset Guarantee or the O&M Guarantee which exists at any time prior to October 1, 1999 (the "New Guarantee Exposure"), Motorola shall be paid cash and IWCL Warrant compensation calculated pursuant to clauses (1), (2) and (3) of Section 3(e) with such New Guarantee Exposure being Motorola Exposure for the purposes of such calculation. (2) For all New Exposure relating to the O&M Deferrals which exists at any time prior to October 1, 1999 (the "O&M New Exposure"), Motorola shall be paid cash compensation in an amount equal to (V) multiplied by (W), where (V) equals the average daily O&M New Exposure for the relevant payment period (with each component of O&M New Exposure to be included in such calculation from the date it is first incurred) multiplied by 0.0003288 (the daily equivalent of 12% interest per annum) and (V) equals the number of days in the relevant payment period. (3) For all New Exposure which exists at any time on or after October 1, 1999 Motorola shall be compensated pursuant to Section 3(a). Prior to October 1, 1999, all New Exposure for which Motorola is compensated pursuant to this Section 3(f) shall not be considered Motorola Exposure for purpose of determining whether the High Yield Equivalent Conditions of Section 3(e) exist and Motorola shall not be compensated for such New Exposure pursuant to any other provisions of this Agreement; provided, however, that New Exposure shall constitute Motorola Exposure in the case of all other provisions of this Agreement and the MOU. For the avoidance of doubt, the parties acknowledge and agree that Motorola Exposure from the Guarantee Increase and the Alternative Guarantee shall be compensated pursuant to Section 3(a) and not as New Exposure (with the entire amount thereof compensated as specified in Section 1(b) of the MOU). Compensation pursuant to this Section 3(f) for each item of New Exposure shall commence no later than the time that (but for this Section 3(f)) it would first constitute Motorola Exposure. (g) Guarantee Reduction. In connection with any permanent reduction of the Commitments under the Bridge Agreement, the O&M Credit Facility or any separate Credit Agreement (subject in the case of the Permanent Bank Facility to Section 1(f) of the MOU), each of Iridium and Operating will use its best efforts to cause the Lenders thereunder to amend the Bridge Agreement Guarantee, O&M Guarantee or other relevant Guarantee, as the case may be, to provide for a similar reduction in Motorola's maximum liability thereunder; and neither Iridium nor Operating will voluntarily cause a permanent reduction in the Commitments under the Bridge Agreement, the O&M Credit Facility or any separate Credit Agreement (subject in the case of the Permanent Bank Facility to Section 1(f) of the MOU), unless a similar reduction in Motorola's maximum liability thereunder is effected no later than the time such permanent reduction is effected. -7- 8 EXECUTION COPY 4.
