The failure to exercise the foregoing option upon the happening of one or more Events of Default shall not constitute a waiver of the right to exercise the same or any other option at any subsequent time in respect of payment hereunder which is less than payment in full of all amounts due and payable at the time of such payments, and shall not constitute a waiver of the right to exercise the foregoing option at that time or at any subsequent time or nullify any prior consent of the holder hereof, except as and to the extent otherwise provided by law. Upon the occurrence and during the continuance of an Event of a Default, the holder hereof may exercise any and all rights and remedies available under contract or applicable law.

By: ------------------------------------ Printed Name: -------------------------- Title: --------------------------------- -2- EXHIBIT "B" ----------- GUARANTY -------- THE UNDERSIGNED, FOR VALUE RECEIVED, unconditionally and absolutely guarantees to HUGHES NETWORK SYSTEMS, INC. (hereinafter called "Lender"), and to the Lender's successors and assigns, as a primary obligation, the prompt and complete payment and performance when due, whether by stated maturity, demand, acceleration or otherwise, of all obligations to the Lender of MAGELLAN INTERNATIONAL, INC., a Delaware corporation, and also of any debtor-in- possession or trustee in bankruptcy which succeeds to the interests of said party or persons (jointly and severally hereinafter called "Borrower"), pursuant to a promissory note or notes made or to be made pursuant to that certain Loan Agreement (hereafter called "Loan Agreement") between Lender and Borrower, said note or notes being in the total principal amount of up to One Billion Seven Hundred Twenty Five Million Dollars ($1,725,000,000.00), all of which is hereinafter collectively called the "Indebtedness." The undersigned waives notice of acceptance of this Guaranty and presentment, demand, protest, notice of protest, dishonor, notice of dishonor, notice of default and diligence in collecting any Indebtedness, and agrees that the Lender may modify the terms of borrowing, compromise, extend, increase, accelerate, renew or forbear to enforce payment of any part or all of any Indebtedness, or permit the Borrower to incur additional Indebtedness, all without notice to the undersigned and without affecting in any manner the unconditional obligation of the undersigned under this Guaranty. The undersigned further waives any and all other notices to which the undersigned might otherwise be entitled. The undersigned acknowledges and agrees that the liabilities created by this Guaranty are direct and are not conditioned upon pursuit by the Lender of any remedy the Lender may have against the Borrower or any other person or any security. No invalidity, irregularity or unenforceability of any part or all of the Indebtedness or any documents evidencing the same, by reason of any bankruptcy, insolvency or other law or order of any kind or for any other reason, and no defense or setoff available at any time to the Borrower, shall impair, affect or be a defense or setoff to the obligations of the undersigned under this Guaranty. The undersigned agrees that no security now or hereafter held by the Lender for the payment of any Indebtedness, whether from the Borrower, any guarantor, or otherwise, and whether in the nature of a security interest, pledge, lien, assignment, setoff, suretyship, guaranty, indemnity, insurance or otherwise, shall affect in any manner the unconditional obligation of the undersigned under this Guaranty, and the Lender, in its sole discretion, without notice to the undersigned, may release, exchange, enforce and otherwise deal with any such security without affecting in any manner the unconditional obligation of the undersigned under this Guaranty. The undersigned acknowledges and agrees that the Lender has no obligation to acquire or perfect any lien on or security interest in any asset or assets, whether realty or personalty, to secure payment of the Indebtedness, and the undersigned is not relying upon assets in which the Lender has or may have a lien or security interest for payment of the Indebtedness. Until the Indebtedness is irrevocably paid in full, the undersigned hereby waives any and all rights to be subrogated to the position of the Lender or to have the benefit of any lien, security interest or other guaranty now or hereafter held by the Lender for the Indebtedness or to enforce any remedy which the Lender now has or hereafter may have against the Borrower or any other person. Until the Indebtedness is irrevocably paid in full, the undersigned shall have no right of reimbursement, indemnity, contribution or other right of recourse to or with respect to the Borrower. The Lender shall have no duty to enforce or protect any rights which the undersigned may have against the Borrower, and the undersigned assumes full responsibility for enforcing and protecting any such rights. If after receipt of any payment of all or any part of the Indebtedness, the Lender is for any reason compelled to surrender such payment to any person or entity because such payment is determined to be void or voidable as a preference, impermissible setoff, or diversion of trust funds or for any other reason, then to the extent of that payment, the Indebtedness shall be revived and the obligations under this Guaranty shall be continued in effect without reduction or discharge for that payment, and this Guaranty shall continue in full force notwithstanding any contrary action which may have been taken by the Lender in reliance upon such payment, and any such contrary action so taken shall be without prejudice to the Lender's rights under this Guaranty and shall be deemed to have been conditioned upon such payment having become final and irrevocable. The undersigned waives any right to require the Lender to: (a) proceed against any person, including the Borrower; (b) proceed against or exhaust any security held from the Borrower or any other person; (c) pursue any other remedy in the Lender's power; or (d) make any presentments or demands for performance, or give any notices of nonperformance, protests, notices of protest or notices of dishonor in connection with any obligations or evidences of Indebtedness held by the Lender as security, in connection with any other obligations or evidences of Indebtedness which constitutes in whole or in part the Indebtedness guaranteed hereunder, or in connection with the creation of new or additional Indebtedness. The undersigned authorizes the Lender, either before or after termination hereof, without notice to or demand on the undersigned and without affecting the undersigned's liability hereunder, from time to time to: (a) apply any security and direct the order or manner of sale thereof, as the Lender in its discretion may determine; (b) release or substitute any one or more of the endorsers or any other guarantors of the Indebtedness; and (c) apply payments received by the Lender from the Borrower to any Indebtedness of the Borrower to the Lender, in such order as the Lender shall determine in its sole discretion, whether or not any such Indebtedness is covered by this Guaranty, and the undersigned hereby waives any provision of law regarding application of payments which specifies otherwise. The Lender may, without notice, assign this Guaranty in whole or in part. The undersigned waives any defense based upon or arising by reason of (a) any disability or other defense of the Borrower or any other person; (b) the cessation or limitation from any cause whatsoever, other than final and irrevocable payment in full, of the -2- Indebtedness; (c) any lack of authority of any officer, director, partner, agent or any other person acting or purporting to act on behalf of the Borrower which is a corporation, partnership or other type of entity, or any defect in the formation of the Borrower; (d) the application by the Borrower of the proceeds of any Indebtedness for purposes other than the purposes represented by the Borrower to the Lender or intended or understood by the Lender or the undersigned; (e) any act or omission by the Lender which directly or indirectly results in or aids in the discharge of the Borrower or any Indebtedness by operation of law or otherwise; or (f) any modification of the Indebtedness, in any form whatsoever, including any modification made after effective termination, and including without limitation the renewal, extension, acceleration or other change in time for payment of the Indebtedness, or other change in the terms of the Indebtedness or any part thereof, including increase or decrease of the rate of interest thereon. The total obligation under this Guaranty shall be One Billion Seven Hundred Twenty Five Million Dollars ($1,725,000,000.00) plus all interest thereon and all costs and expenses of any kind, including but not limited to reasonable attorney fees, incurred by the Lender at any time for any reason in enforcing any of the duties and obligations of the undersigned under this Guaranty or otherwise incurred by the Lender in any way connected with this Guaranty, the Indebtedness. All such costs and expenses shall be payable immediately by the undersigned when incurred by the Lender, without demand, and until paid shall bear interest at the hightest per annum rate applicable to any of the Indebtedness, but not in excess of the maximum rate permitted by law. Any reference in this Guaranty to attorney fees shall be deemed a reference to fees, charges, costs and expenses of both in-house and outside counsel, whether or not a suit or action is instituted, and to court costs if a suite or action is instituted, and whether such attorney fees or court costs are incurred at the trial court level, on appeal, in a bankruptcy or probate proceeding or otherwise. The undersigned unconditionally and irrevocably waives each and every defense and setoff of any nature which, under principles of guaranty or otherwise, would operate to impair or diminish in any way the obligation of the undersigned under this Guaranty, and acknowledges that as of the date hereof no such defense or setoff exits. The undersigned warrants and agrees that each of the waivers set forth above are made with the undersigned's full knowledge of its significance and consequences, and that under the circumstances, the waivers are reasonable and not contrary to public policy or law. If any of said waivers are determined to be contrary to any applicable law or public policy, such waivers shall be effective only to the extent permitted by law. This Guaranty constitutes the entire agreement of the undersigned and the Lender with respect to the subject matter hereof. No waiver, consent, modification or change of the terms of this Guaranty shall bind the undersigned or the Lender unless in writing and signed by the waiving party or an authorized officer of the waiving party, and then such waiver, consent, modification or change shall be effective only in the specific instance and for the specific purpose given. This Guaranty shall inure to the benefit of the Lender and its successors and -3- assigns. This Guaranty shall be binding on the undersigned and the undersigned's heirs, legal representatives, successors and assigns including, without limiting the generality of the foregoing, any debtor-in-possession or trustee in bankruptcy for the undersigned. The undersigned has entered into this Guaranty in good faith for the purpose of inducing the Lender to extend credit or make other financial accommodations to the Borrower, and the undersigned acknowledges that the terms hereof are reasonable. If any provision of this Guaranty is unenforceable in whole or in part for any reason, the remaining provisions shall continue to be effective. THIS GUARANTY SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. As used herein, the singular shall be deemed to include plural, and vice ---- versa, as the context requires. - ----- IN WITNESS WHEREOF the undersigned has signed this Guaranty on ____________________________.
