EXHIBIT 10.69 GUARANTY OF DATRON SYSTEMS INCORPORATED OF THE INDEBTEDNESS OF DATRON WORLD COMMUNICATIONS INC. AND DATRON/TRANSCO INC. TO COMERICA BANK-CALIFORNIA DATED MARCH 24, 1999 Guaranty As of March 24, 1999, the undersigned, for value received, unconditionally and absolutely guarantees to Comerica Bank - California ("Bank"), a California banking corporation, payment when due, whether by stated maturity, demand, acceleration or otherwise, of all existing and future indebtedness ("Indebtedness") to the Bank of Datron World Communications Inc., a California corporation ("DWC"), and Datron/Transco Inc., a California corporation ("DT", and together with DWC, "Borrower"). Indebtedness includes without limit any and all obligations or liabilities of the Borrower to the Bank, whether absolute or contingent, direct or indirect, voluntary or involuntary, liquidated or unliquidated, joint or several, known or unknown; any and all indebtedness, obligations or liabilities for which Borrower would otherwise be liable to the Bank were it not for the invalidity, irregularity or unenforceability of them by reason of any bankruptcy, insolvency or other law or order of any kind, or for any other reason; all amendments, modifications, renewals and/or extensions of the above; and all costs of collecting Indebtedness, including, without limit, attorney fees. Any reference in this Guaranty to attorney fees shall be deemed a reference to reasonable fees, charges, costs and expenses of both in-house and outside counsel and paralegals, whether or not a suit or action is instituted, and to court costs if a suit or action is instituted, and whether attorney fees or court costs are incurred at the trial court level, on appeal, in a bankruptcy, administrative or probate proceeding or otherwise. All costs shall be payable by the undersigned when incurred by the Bank, without demand, and if not paid within ten (10) business days of when first due, shall bear interest at the default rate of interest applicable to the Indebtedness under Borrower's agreements with Bank until paid in full, but not in excess of the maximum rate permitted by law. 1. LIMITATION: The total obligation of the undersigned under this Guaranty shall include, IN ADDITION TO the principal guaranteed, all interest on the principal amount, and all costs incurred by the Bank in collection efforts against the Borrower and/or the undersigned or otherwise incurred by the Bank in any way relating to the Indebtedness, or this Guaranty, including without limit attorney fees. The undersigned agrees that (a) this limitation shall not be a limitation on the amount of Borrower's Indebtedness to the Bank; (b) any payments by the undersigned shall not reduce the maximum liability of the undersigned under this Guaranty unless written notice to that effect is actually received by the Bank at, or prior to, the time of the payment; and (c) the liability of the undersigned to the Bank shall at all times be deemed to be the aggregate liability of the undersigned under this Guaranty and any other guaranties previously or subsequently given to the Bank by the undersigned and not expressly revoked, modified or invalidated in writing. 2. NATURE OF GUARANTY: This is a continuing Guaranty of payment and not of collection, and remains effective whether the Indebtedness is from time to time reduced and later increased or entirely extinguished and later reincurred. The undersigned delivers this Guaranty based solely on the undersigned's independent investigation of (or decision not to investigate) the financial condition of Borrower and is not relying on any information furnished by the Bank. The undersigned assumes full responsibility for obtaining any further information concerning the Borrower's financial condition, the status of the Indebtedness or any other matter which the undersigned may deem necessary or appropriate now or later. The undersigned knowingly accepts the full range of risk encompassed in this Guaranty, which risk includes, without limit, the possibility that Borrower may incur Indebtedness to the Bank after the financial condition of the Borrower, or the Borrower's ability to pay debts as they mature, has deteriorated. 3. APPLICATION OF PAYMENTS: The undersigned authorizes the Bank, either before or after termination of this Guaranty, without notice to or demand on the undersigned and without affecting the undersigned's liability under this Guaranty, from time to time to: (a apply any security and direct the order or manner of sale; and (b) apply payments received by the Bank from the Borrower to any indebtedness of the Borrower to the Bank, in such order as the Bank shall determine in its sole discretion, whether or not this indebtedness is covered by this Guaranty, and the undersigned waives any provision of law regarding application of payments which specifies otherwise. The undersigned agrees to provide to the Bank copies of the undersigned's financial statements upon request. 4. SETOFF: The undersigned acknowledges the Bank's right of setoff as to any and all deposits and other amounts from time to time in the possession of, or owing to the undersigned by, the Bank. The undersigned further assigns to the Bank as collateral for the obligations of the undersigned under this Guaranty all claims of any nature that the undersigned now or later has (have) against the Borrower (other than any claim under a deed of trust or mortgage covering California real property) with full right on the part of the Bank, in its own name or in the name of the undersigned, to collect and enforce these claims. The undersigned agrees that no security now or later held by the Bank 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 Bank, in its sole discretion, without notice to the undersigned, may release, exchange, enforce and otherwise deal with any security without affecting in any manner the unconditional obligation of the undersigned under this Guaranty. The undersigned acknowledges and agrees that the Bank has no obligation to acquire or perfect any lien on or security interest in any asset(s), whether realty or personalty, to secure payment of the Indebtedness, and the undersigned is not relying upon any asset(s) in which the Bank has or may have a lien or security interest for payment of the Indebtedness. 5. OTHER GUARANTORS: If any Indebtedness is guaranteed by two or more guarantors, the obligation of the undersigned shall be several and also joint, each with all and also each with any one or more of the others, and may be enforced at the option of the Bank against each severally, any two or more jointly, or some severally and some jointly. The Bank, in its sole discretion, may release any one or more of the guarantors for any consideration which it deems adequate, and may fail or elect not to prove a claim against the estate of any bankrupt, insolvent, incompetent or deceased guarantor; and after that, without notice to any guarantor, the Bank may extend or renew any or all Indebtedness and may permit the Borrower to incur additional Indebtedness, without affecting in any manner the unconditional obligation of the remaining guarantor(s). The undersigned acknowledges that the effectiveness of this Guaranty is not conditioned on any or all of the indebtedness being guaranteed by anyone else. 6. TERMINATION: The undersigned may not terminate its obligation under this Guaranty as to future Indebtedness (except as provided below) by (and only by) delivering written notice of termination to an officer of the Bank and receiving from an officer of the Bank written acknowledgment of delivery; provided, however, the termination shall not be effective until the opening of business on the fifth (5th) day ("effective date") following written acknowledgment of delivery. Any termination shall not affect in any way the unconditional obligations of the remaining guarantor(s), if any, whether or not the termination is known to the remaining guarantor(s). Any termination shall not affect in any way the unconditional obligations of the terminating guarantor(s) as to any Indebtedness existing at the effective date of termination or any Indebtedness created after that pursuant to any commitment or agreement of the Bank or pursuant to any Borrower loan with the Bank existing at the effective date of termination (whether advances or readvances by the Bank after the effective date of termination are optional or obligatory), or any modifications, extensions or renewals of any of this Indebtedness, whether in whole or in part, and as to all of this Indebtedness and modifications, extensions or renewals of it, this Guaranty shall continue effective until the same shall have been fully paid. The Bank has no duty to give notice of termination by any guarantor(s) to any remaining guarantor(s). The undersigned shall indemnify the Bank against all claims, damages, costs and expenses, including, without limit, attorney fees, incurred by the Bank in connection with any suit, claim or action against the Bank arising out of any modification or termination of a Borrower loan or any refusal by the Bank to extend additional credit in connection with the termination of this Guaranty. 7. REINSTATEMENT: Notwithstanding any prior revocation, termination, surrender or discharge of this Guaranty (or of any lien, pledge or security interest securing this Guaranty) in whole or in part, the effectiveness of this Guaranty, and of all liens, pledges and security interests securing this Guaranty, shall automatically continue or be reinstated in the event that any payment received or credit given by the Bank in respect of the Indebtedness is returned, disgorged or rescinded under any applicable state or federal law, including, without limitation, laws pertaining to bankruptcy or insolvency, in which case this Guaranty, and all liens, pledges and security interests securing this Guaranty, shall be enforceable against the undersigned as if the returned, disgorged or rescinded payment or credit had not been received or given by the Bank, and whether or not the Bank relied upon this payment or credit or changed its position as a consequence of it. In the event of continuation or reinstatement of this Guaranty and the liens, pledges and security interests securing it, the undersigned agrees upon demand by the Bank, to execute and deliver to the Bank those documents which the Bank determines are appropriate to further evidence (in the public records or otherwise) this continuation or reinstatement, although the failure of the undersigned to do so shall not affect in any way the reinstatement or continuation. If the undersigned does not execute and deliver to the Bank upon demand such documents, the Bank and each Bank officer is irrevocably appointed (which appointment is coupled with an interest) the true and lawful attorney of the undersigned (with full power of substitution) to execute and deliver such documents in the name and on behalf of the undersigned. 8. WAIVERS: The undersigned waives any right to require the Bank to: (a) proceed against any person or property; (b) give notice of the terms, time and place of any public or private sale of personal property security held from the Borrower or any other person, or otherwise comply with the provisions of Section 9-504 of the California Uniform Commercial Code or other applicable Uniform Commercial Code; or (c) pursue any other remedy in the Bank's power. The undersigned waives notice of acceptance of this Guaranty and presentment, demand, protest, notice of protest, dishonor, notice of dishonor, notice of default, notice of intent to accelerate or demand payment of any Indebtedness, any and all other notices to which the undersigned might otherwise be entitled, and diligence in collecting any Indebtedness, and agrees that the Bank may, once or any number of times, modify the terms of any Indebtedness, compromise, extend, increase, accelerate, renew or forbear to enforce payment of any or all 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 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 each such waiver is by this reference incorporated into each security agreement, collateral assignment, pledge and/or other document from the undersigned now or later securing this Guaranty and/or the Indebtedness, and acknowledges that as of the date of this Guaranty no such defense or setoff exists. The undersigned understands that, absent this waiver, Bank's election of remedies, including but not limited to its decision to proceed to nonjudicial foreclosure on any real property securing the Indebtedness, could preclude Bank from obtaining a deficiency judgment against Borrower and the undersigned pursuant to California Code of Civil Procedures Sections 580a, 580b, 580d or 726 and could also destroy any subrogation rights which the undersigned has against Borrower. The undersigned further understands that, absent this waiver, California law, including without limitation, California Code of Civil Procedure Sections 580a, 580b, 580d or 726, could afford the undersigned one or more affirmative defenses to any action maintained by Bank against the undersigned on this Guaranty. Although, the intent of the undersigned and the Bank is that California law shall apply, the undersigned waives any and all rights and provisions of California Code of Civil Procedure Sections 580a, 580b, 580d and 726, including, but not limited to any provision thereof that: (i) may limit the time period for Bank to commence a lawsuit against Borrower or the undersigned to collection any Indebtedness owing by Borrower or the undersigned to Bank; (ii) may entitle Borrower or the undersigned to a judicial or nonjudicial determination of any deficiency owed by Borrower or the undersigned to Bank, or to otherwise limit Bank's right to collect a deficiency based on the fair market value of such real property security; (iii) may limit Bank's right to collect a deficiency judgment after a sale of any real property securing the indebtedness; (iv) may require Bank to take only one action to collect the indebtedness or that may otherwise limit the remedies available to Bank to collect the Indebtedness. Although, the intent of the undersigned and the Bank is that California law shall apply, the undersigned waives all rights and defenses arising out of an election of remedies by Bank even though that election of remedies, such as a nonjudicial foreclosure with respect to security for a guarantee obligation, has destroyed the undersigned's rights of subrogation and reimbursement against Borrower by the operation of Section 580d of the Code of Civil Procedure or otherwise. 9. WAIVER OF SUBROGATION: The undersigned postpones any and all rights (whether by subrogation, indemnity, reimbursement, or otherwise) to recover from the Borrower any amounts paid by the undersigned pursuant to this Guaranty until such time that all Indebtedness has been finally and irrevocably paid to Bank. 10. SALE/ASSIGNMENT: The undersigned acknowledges that the Bank has the right to sell, assign, transfer, negotiate, or grant participations in all or any part of the Indebtedness and any related obligations, including, without limit, this Guaranty, without notice to the undersigned and that the Bank may disclose any documents and information which the Bank now has or later acquires relating to the undersigned or to the Borrower in connection with such sale, assignment, transfer, negotiation, or grant. The undersigned agrees that the Bank may provide information relating to this Guaranty or relating to the undersigned to the Bank's parent, affiliates, subsidiaries and service providers. 11. WITHHOLDING TAXES: All payments to be made by the undersigned under this Guaranty shall be made without setoff or counterclaim and without deduction for or on account of any present or future withholding or other taxes of any nature imposed by any governmental authority or of any political subdivision thereof or any federation or organization of which such governmental authority may at the time of payment be a member, unless the undersigned is compelled by law to make payment subject to such tax. In such event, the undersigned shall: (a) pay to the Bank for the account of the Bank such additional amounts as may be necessary to ensure that the Bank receives a net amount equal to the full amount which would have been receivable under this Guaranty had payment not been made subject to such tax; and (b) send to the Bank such certificates or certified copies of receipts as the Bank shall reasonably require as proof of the payment by the undersigned of any such taxes payable by the undersigned. As used herein, the terms "tax", "taxes" and "taxation" include all existing taxes, levies, imposts, duties, charges, fees, deductions and withholdings and any restrictions or conditions resulting in a charge, together with interest thereon and fines and penalties with respect thereto, which may be imposed by reason of any violation or default with respect to the law regarding such tax, assessed as a result of or in connection with the Indebtedness or the obligation of the undersigned hereunder, or the payment or delivery of funds into or out of any jurisdiction other than the United States (whether assessed against Borrower, the undersigned or the Bank). 12. GENERAL: This Guaranty constitutes the entire agreement of the undersigned and the Bank with respect to the subject matter of this Guaranty. No waiver, consent, modification or change of the terms of the Guaranty shall bind any of the undersigned or the Bank unless in writing and signed by the waiving party or an authorized officer of the waiving party, and then this 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 Bank and its successors and assigns and shall be binding on the undersigned and the undersigned's heirs, legal representatives, successors and assigns including, without limit, any debtor in possession or trustee in bankruptcy for any of the undersigned.
