EXHIBIT 10.03 EXECUTION COPY GUARANTY This GUARANTY ("Guaranty") is made as of the ___ day of February, 1998, by [_______________], a [___________] corporation (the "Guarantor"), in favor of the "Holders of Secured Obligations" under (and as defined in) that certain Credit Agreement, of even date herewith, by and among IFR SYSTEMS, INC. (the "Borrower"), the financial institutions from time to time parties thereto (collectively the "Lenders") and The First National Bank of Chicago, in its capacity as contractual representative for the Holders of Secured Obligations (the "Agent"). Such Credit Agreement, as it may be amended, modified or supplemented from time to time, is hereinafter referred to as the "Credit Agreement". Unless otherwise defined herein, capitalized terms used herein shall have the meanings ascribed to them in the Credit Agreement. 1. GUARANTY. (i) For value received and in consideration of any loan, advance or financial accommodation of any kind whatsoever heretofore, now or hereafter made, given or granted to the Borrower by the Holders of Secured Obligations, the Guarantor unconditionally guarantees for the benefit of each of the Holders of Secured Obligations the full and prompt payment when due, whether at maturity or earlier, by reason of acceleration or otherwise, and at all times thereafter, of all of the Secured Obligations (including, without limitation, interest accruing following the filing of a bankruptcy petition by or against the Borrower, at the applicable rate specified in the Credit Agreement, whether or not such interest is allowed as a claim in bankruptcy). (ii) At any time after the occurrence of a Default, the Guarantor shall pay to the Agent, for the benefit of the Holders of Secured Obligations, on demand and in immediately available funds, the full amount of the Secured Obligations (including any portion thereof which is not yet due and payable). The Guarantor further agrees to pay to the Agent and reimburse the Agent for, on demand and in immediately available funds, (a) all losses (including, without limitation, lost profits), fees, costs and expenses (including, without limitation, all court costs and attorneys' and paralegals' fees, costs and expenses) paid or incurred by the Agent or any of the Holders of Secured Obligations in: (1) endeavoring to collect all or any part of the Secured Obligations from, or in prosecuting any action against, the Borrower or the Guarantor relating to the Credit Agreement, this Guaranty or the transactions contemplated thereby; (2) taking any action with respect to any security or collateral securing the Secured Obligations or the Guarantor's obligations hereunder; and (3) preserving, protecting or defending the enforceability of, or enforcing, this Guaranty or their respective rights hereunder (all such costs and expenses are hereinafter referred to as the "Expenses") and (b) interest on (1) the Secured Obligations which do not constitute interest, (2) to the extent permitted by applicable law, the Secured Obligations which constitute interest, and (3) the Expenses, from the date of demand under this Guaranty until paid in full at the per annum rate of interest described in Section 2.11 of the Credit Agreement (the "Interest Rate"). The Guarantor hereby agrees that this Guaranty is an absolute guaranty of payment and is not a guaranty of collection. -2- 2. OBLIGATIONS UNCONDITIONAL. The Guarantor hereby agrees that its obligations under this Guaranty shall be unconditional, irrespective of: (i) the validity, enforceability, avoidance, novation or subordination of any of the Secured Obligations or any of the Loan Documents; (ii) the absence of any attempt by, or on behalf of, any Holder of Secured Obligations or the Agent to collect, or to take any other action to enforce, all or any part of the Secured Obligations whether from or against the Borrower, any other guarantor of the Secured Obligations or any other Person; (iii) the election of any remedy by, or on behalf of, any Holder of Secured Obligations or the Agent with respect to all or any part of the Secured Obligations; (iv) the waiver, consent, extension, forbearance or granting of any indulgence by, or on behalf of, any Holder of Secured Obligations or the Agent with respect to any provision of any of the Loan Documents; (v) the failure of the Agent to take any steps to perfect and maintain its security interest in, or to preserve its rights to, any security or collateral for the Secured Obligations; (vi) the election by, or on behalf of, any one or more of the Holders of Secured Obligations, in any proceeding instituted under Chapter 11 of Title 11 of the United States Code (11 U.S.C. 101 et seq.) (the "Bankruptcy Code"), of the application of Section 1111(b)(2) of the Bankruptcy Code; (vii) any borrowing or grant of a security interest by the Borrower, as debtor-in-possession, under Section 364 of the Bankruptcy Code; (viii) the disallowance, under Section 502 of the Bankruptcy Code, of all or any portion of the claims of any of the Holders of Secured Obligations or the Agent for repayment of all or any part of the Secured Obligations or any Expenses; or (ix) any other circumstance which might otherwise constitute a legal or equitable discharge or defense of the Borrower or the Guarantor. 3. ENFORCEMENT; APPLICATION OF PAYMENTS. Upon the occurrence of a Default, the Agent may proceed directly and at once, without notice, against the Guarantor to obtain performance of and to collect and recover the full amount, or any portion, of the Secured Obligations, without first proceeding against the Borrower or any other Person, or against any security or collateral for the Secured Obligations. Subject only to the terms and provisions of the Credit Agreement, the Agent shall have the exclusive right to determine the application of payments and credits, if any, from the Guarantor, the Borrower or from any other Person on account of the Secured Obligations or any other liability of the Guarantor to any Holder of Secured Obligations. -3- 4. REPRESENTATIONS AND WARRANTIES. The Guarantor represents and warrants as follows to each Holder of Secured Obligations and the Agent as of the date hereof: (i) The Guarantor (a) is a corporation duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization, (b) is duly qualified to do business as a foreign corporation and is in good standing under the laws of each jurisdiction in which failure to be so qualified and in good standing could reasonably be expected to have a Material Adverse Effect, and (c) has all requisite corporate power and authority to own, operate and encumber its property; (ii) The Guarantor has the requisite corporate power and authority to execute, deliver and perform this Guaranty and any other document required to be delivered by it under the Credit Agreement, and this Guaranty has been duly executed and delivered and constitutes the legal, valid and binding obligation of the Guarantor enforceable against the Guarantor in accordance with its terms; and (iii) The execution, delivery and performance of this Guaranty do not and will not (a) conflict with the Articles of Incorporation or by-laws of the Guarantor, (b) require any approval of the Guarantor's shareholders except such as has been obtained, (c) require any approval or consent of any Person or Governmental Authority, or under the terms of any material agreement, and (d) will not result in or require the creation of any lien or security interest upon or with respect to any of the properties or assets of the Guarantor other than pursuant to the Loan Documents. 5. WAIVERS. (i) The Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of receivership or bankruptcy of the Borrower, protest or notice with respect to the Secured Obligations, all setoffs and counterclaims and all presentments, demands for performance, notices of nonperformance, protests, notices of protest, notices of dishonor and notices of acceptance of this Guaranty, the benefits of all statutes of limitation, and all other demands whatsoever (and shall not require that the same be made on the Borrower as a condition precedent to the Guarantor's obligations hereunder), and covenants that this Guaranty will not be discharged, except by complete payment (in cash) and performance of the Secured Obligations and any other obligations contained herein. The Guarantor further waives all notices of the existence, creation or incurring of new or additional indebtedness, arising either from additional loans extended to the Borrower or otherwise, and also waives all notices that the principal amount, or any portion thereof, and/or any interest on any instrument or document evidencing all or any part of the Secured Obligations is due, notices of any and all proceedings to collect from the maker, any endorser or any other guarantor of all or any part of the Secured Obligations, or from any other Person, and, to the extent permitted by law, notices of exchange, sale, -4- surrender or other handling of any security or collateral given to the Agent to secure payment of all or any part of the Secured Obligations. (ii) The Guarantor understands that it shall be liable for the full amount of its liability under this Guaranty, notwithstanding foreclosure of any real property securing all or any part of the Secured Obligations by trustee sale or any other reason impairing the right of the Guarantor, the Agent or any of the Holders of Secured Obligations to proceed against the Borrower, any other guarantor or the Borrower's or such guarantor's property. The Guarantor agrees that all of its obligations under this Guaranty (including its obligation to pay in full all indebtedness evidenced by or arising under the Credit Agreement) shall remain in full force and effect without defense, offset or counterclaim of any kind, notwithstanding that the Guarantor's rights against the Borrower may be impaired, destroyed or otherwise affected by reason of any action or inaction on the part of the Agent or any Holder of Secured Obligations. (iii) The Guarantor hereby expressly waives the benefits of any law in any jurisdiction applicable to this Guaranty purporting to allow a guarantor to revoke a continuing guaranty with respect to any transactions occurring after the date of the guaranty. (iv) The Holders of Secured Obligations, either themselves or acting through the Agent, may from time to time in their sole discretion, without notice or demand and without affecting the liability of the Guarantor hereunder, (a) renew, extend, accelerate or otherwise change the time for payment of, or other terms relating to, all or any part of the Secured Obligations, or otherwise modify, amend or change the terms of any of the Loan Documents; (b) accept partial payments on all or any part of the Secured Obligations; (c) take and hold security or collateral for the payment of all or any part of the Secured Obligations, this Guaranty, or any other guaranties of all or any part of the Secured Obligations or other liabilities of the Borrower, (d) exchange, enforce, waive and release any such security or collateral; (e) apply such security or collateral and direct the order or manner of sale thereof as in their discretion they may determine; (f) settle, release, exchange, enforce, waive, compromise or collect or otherwise liquidate all or any part of the Secured Obligations, this Guaranty, any other guaranty of all or any part of the Secured Obligations, and any security or collateral for the Secured Obligations or for any such guaranty; and/or (g) otherwise deal with the Borrower or any other Person that may become liable for all or any part of the Secured Obligations. Any of the foregoing may be done in any manner, without affecting or impairing the obligations of the Guarantor hereunder. 6. SETOFF. At any time after all or any part of the Secured Obligations have become due and payable (by acceleration or otherwise), each Holder of Secured Obligations and the Agent may, without notice to the Guarantor and regardless of the acceptance of any security or collateral for the payment hereof, appropriate and apply toward the payment of all or any part of the Secured Obligations (i) any indebtedness due or to become due from such Holder of Secured Obligations or the Agent to the Guarantor, and (ii) any moneys, credits or other property belonging to the Guarantor, at any time held by or coming into the possession of such Holder of Secured Obligations or the Agent or any of their respective affiliates. 7. FINANCIAL INFORMATION. The Guarantor hereby assumes responsibility for keeping itself informed of the financial condition of the Borrower and any and all endorsers -5- and/or other guarantors of all or any part of the Secured Obligations, and of all other circumstances bearing upon the risk of nonpayment of the Secured Obligations, or any part thereof, that diligent inquiry would reveal, and the Guarantor hereby agrees that none of the Holders of Secured Obligations nor the Agent shall have any duty to advise the Guarantor of information known to any of them regarding such condition or any such circumstances. In the event any Holder of Secured Obligations, in its sole discretion, undertakes at any time or from time to time to provide any such information to the Guarantor, such Holder of Secured Obligations shall be under no obligation (i) to undertake any investigation not a part of its regular business routine, (ii) to disclose any information which such Holder of Secured Obligations, pursuant to accepted or reasonable commercial finance or banking practices, wishes to maintain confidential or (iii) to make any other or future disclosures of such information or any other information to the Guarantor. 8. NO MARSHALLING; REINSTATEMENT. The Guarantor consents and agrees that none of the Holders of Secured Obligations nor the Agent nor any Person acting for or on behalf of the Holders of Secured Obligations or the Agent shall be under any obligation to marshall any assets in favor of the Guarantor or against or in payment of any or all of the Secured Obligations. The Guarantor further agrees that, to the extent that the Borrower, the Guarantor or any other guarantor of all or any part of the Secured Obligations makes a payment or payments to any Holder of Secured Obligations or the Agent, or any Holder of Secured Obligations or the Agent receives any proceeds of Collateral, which payment or payments or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside and/or required to be repaid to the Borrower, the Guarantor, such other guarantor or any other Person, or their respective estates, trustees, receivers or any other party, including, without limitation, the Guarantor, under any bankruptcy law, state or federal law, common law or equitable cause, then, to the extent of such payment or repayment, the part of the Secured Obligations which has been paid, reduced or satisfied by such amount shall be reinstated and continued in full force and effect as of the time immediately preceding such initial payment, reduction or satisfaction. 9. SUBROGATION. Until the Secured Obligations have been paid in full, the Guarantor (i) shall have no right of subrogation with respect to such Secured Obligations and (ii) waives any right to enforce any remedy which the Holders of Secured Obligations or the Agent (or any of them) now have or may hereafter have against the Borrower, any endorser or any guarantor of all or any part of the Secured Obligations or any other Person, and the Guarantor waives any benefit of, and any right to participate in, any security or collateral given to the Holders of Secured Obligations and the Agent (or any of them) to secure the payment or performance of all or any part of the Secured Obligations or any other liability of the Borrower to the Holders of Secured Obligations. 10. SUBORDINATION. The Guarantor agrees that any and all claims of the Guarantor against the Borrower, any endorser or any other guarantor of all or any part of the Secured Obligations, or against any of their respective properties, shall be subordinate and subject in right of payment to the prior payment, in full and in cash, of all Secured Obligations. Notwithstanding any right of the Guarantor to ask, demand, sue for, take or receive any payment from the Borrower, all rights, liens and security interests of the Guarantor, whether now or hereafter arising and howsoever existing, in any assets of the Borrower (whether constituting part of the security or collateral given to any Holder of -6- Secured Obligations or the Agent to secure payment of all or any part of the Secured Obligations or otherwise) shall be and hereby are subordinated to the rights of the Holders of Secured Obligations and the Agent in those assets. The Guarantor shall have no right to possession of any such asset or to foreclose upon any such asset, whether by judicial action or otherwise, unless and until all of the Secured Obligations shall have been fully paid and satisfied and all financing arrangements between the Borrower and the Holders of Secured Obligations have been terminated. If all or any part of the assets of the Borrower, or the proceeds thereof, are subject to any distribution, division or application to the creditors of the Borrower, whether partial or complete, voluntary or involuntary, and whether by reason of liquidation, bankruptcy, arrangement, receivership, assignment for the benefit of creditors or any other action or proceeding, or if the business of the Borrower is dissolved or if substantially all of the assets of the Borrower are sold, then, and in any such event, any payment or distribution of any kind or character, either in cash, securities or other property, which shall be payable or deliverable upon or with respect to any indebtedness of the Borrower to the Guarantor ("Borrower Indebtedness") shall be paid or delivered directly to the Agent for application on any of the Secured Obligations, due or to become due, until such Secured Obligations shall have first been fully paid and satisfied. The Guarantor irrevocably authorizes and empowers the Agent to demand, sue for, collect and receive every such payment or distribution and give acquittance therefor and to make and present for and on behalf of the Guarantor such proofs of claim and take such other action, in the Agent's own name or in the name of the Guarantor or otherwise, as the Agent may deem necessary or advisable for the enforcement of this Guaranty. The Agent may vote such proofs of claim in any such proceeding, receive and collect any and all dividends or other payments or disbursements made thereon in whatever form the same may be paid or issued and apply the same on account of any of the Secured Obligations. Should any payment, distribution, security or instrument or proceeds thereof be received by the Guarantor upon or with respect to the Borrower Indebtedness prior to the satisfaction of all of the Secured Obligations and the termination of all financing arrangements between the Borrower and the Holders of Secured Obligations, the Guarantor shall receive and hold the same in trust, as trustee, for the benefit of the Holders of Secured Obligations and shall forthwith deliver the same to the Agent, for the benefit of the Holders of Secured Obligations, in precisely the form received (except for the endorsement or assignment of the Guarantor where necessary), for application to any of the Secured Obligations, due or not due, and, until so delivered, the same shall be held in trust by the Guarantor as the property of the Holders of Secured Obligations. If the Guarantor fails to make any such endorsement or assignment to the Agent, the Agent or any of its officers or employees are hereby irrevocably authorized to make the same. The Guarantor agrees that until the Secured Obligations have been paid in full (in cash) and satisfied and all financing arrangements between the Borrower and the Holders of Secured Obligations have been terminated, the Guarantor will not assign or transfer to any Person any claim the Guarantor has or may have against the Borrower. 11. ENFORCEMENT; AMENDMENTS; WAIVERS. No delay on the part of any of the Holders of Secured Obligations or the Agent in the exercise of any right or remedy arising under this Guaranty, the Credit Agreement, any of the other Loan Documents or otherwise with respect to all or any part of the Secured Obligations, the Collateral or any other guaranty of or security for all or any part of the Secured Obligations shall operate as a waiver thereof, and no single or partial exercise by any such Person of any such right or remedy shall preclude any further exercise thereof. No modification or waiver of any of the -7- provisions of this Guaranty shall be binding upon the Holders of Secured Obligations or the Agent, except as expressly set forth in a writing duly signed and delivered by the party making such modification or waiver. Failure by any of the Holders of Secured Obligations or the Agent at any time or times hereafter to require strict performance by the Borrower, the Guarantor, any other guarantor of all or any part of the Secured Obligations or any other Person of any of the provisions, warranties, terms and conditions contained in any of the Loan Documents now or at any time or times hereafter executed by such Persons and delivered to the Agent or any Holder of Secured Obligations shall not waive, affect or diminish any right of the Agent or such Holder of Secured Obligations at any time or times hereafter to demand strict performance thereof and such right shall not be deemed to have been waived by any act or knowledge of the Agent or any Holder of Secured Obligations, or their respective agents, officers or employees, unless such waiver is contained in an instrument in writing, directed and delivered to the Borrower or the Guarantor, as applicable, specifying such waiver, and is signed by the party or parties necessary to give such waiver under the Credit Agreement. No waiver of any Default by the Agent or any Holder of Secured Obligations shall operate as a waiver of any other Default or the same Default on a future occasion, and no action by the Agent or any Holder of Secured Obligations permitted hereunder shall in any way affect or impair the Agent's or any Holder of Secured Obligations's rights and remedies or the obligations of the Guarantor under this Guaranty. Any determination by a court of competent jurisdiction of the amount of any principal and/or interest owing by the Borrower to any of the Holders of Secured Obligations shall be conclusive and binding on the Guarantor irrespective of whether the Guarantor was a party to the suit or action in which such determination was made. 12. EFFECTIVENESS; TERMINATION. This Guaranty shall become effective upon its execution by the Guarantor and shall continue in full force and effect and may not be terminated or otherwise revoked until the Secured Obligations shall have been fully paid (in cash) and discharged and the Credit Agreement and all financing arrangements between the Borrower and the Holders of Secured Obligations shall have been terminated. If, notwithstanding the foregoing, the Guarantor shall have any right under applicable law to terminate or revoke this Guaranty, the Guarantor agrees that such termination or revocation shall not be effective until a written notice of such revocation or termination, specifically referring hereto, signed by the Guarantor, is actually received by the Agent. Such notice shall not affect the right and power of any of the Holders of Secured Obligations or the Agent to enforce rights arising prior to receipt thereof by the Agent. If any Holder of Secured Obligations grants loans or takes other action after the Guarantor terminates or revokes this Guaranty but before the Agent receives such written notice, the rights of such Holder of Secured Obligations with respect thereto shall be the same as if such termination or revocation had not occurred. 13. SUCCESSORS AND ASSIGNS. This Guaranty shall be binding upon the Guarantor and upon its successors and assigns and shall inure to the benefit of the Holders of Secured Obligations and the Agent and their respective successors and assigns; all references herein to the Borrower and to the Guarantor shall be deemed to include their respective successors and assigns.
