EXHIBIT 10.10

PROMISSORY NOTE

$40,000.00 July 27, 2001

        FOR VALUE RECEIVED, David L. Hattey (the "Borrower") promises to pay to
the order of Transcrypt International, Inc., a Delaware corporation ("the
"Lender"), the principal sum of Forty Thousand Dollars ($40,000.00), with no
interest (except as otherwise provided herein). Said principal amount shall be
due and payable on or before July 27, 2004. Payments due hereunder shall be
personally delivered by the Borrower to Lender at 4800 N.W. 1st Street, Lincoln,
Nebraska 68521, or to such other address as Lender may designate in writing.

        Payments on the outstanding principal balance owed hereunder shall be
paid by Borrower to Lender on or before the last day of March in calendar years
2002, 2003 and 2004. The amount of each payment shall be equal to fifty percent
(50%) of the amount of any bonus paid to Borrower by Lender not to exceed one
third of the original principal in any give bonus, net of any applicable
standard taxes and/or deductions, in each such calendar year. Borrower hereby
expressly authorizes the Lender to withhold and retain said amounts from any
bonus to be paid to Borrower by Lender in calendar years 2002, 2003 and 2004 for
the purpose of applying said amounts toward payment and satisfaction of the
obligations owed to Lender by Borrower hereunder. The entire remaining unpaid
principal balance owed hereunder shall be due and payable in a single lump sum
on or before July 27, 2004.

        Borrower shall have the right to prepay the principal amount due
hereunder at any time, in whole or in part, without penalty or premium;
provided, however, any partial prepayment shall not postpone the due date of any
subsequent payment contemplated hereunder.

        Upon the occurrence of any Event of Default (as hereinafter defined),
the principal amount then due shall, from the date of such Event of Default,
bear interest at an annual rate equal to the then-current one-year Treasury Bill
interest rate as of the date of Default, as published in The Wall Street
Journal, until paid in full.

        Borrower acknowledges and agrees that an event of default shall be
deemed to have occurred hereunder upon the occurrence of any one or more of the
following events (an "Event of Default"):

(a)The failure of Borrower to pay Lender any portion of the principal balance
owed hereunder when due;

(b)The failure or refusal of the Borrower to punctually and properly perform,
observe and comply with any covenant, agreement or condition contained herein;

(c)The termination of Borrower's employment with Lender because of death,
resignation, removal or any other cause or reason whatsoever; or

(d)Borrower shall (i) be adjudicated a bankrupt or insolvent, or admit in
writing his inability to pay his debts as they mature, (ii) make an assignment
for the benefit of creditors, (iii) apply for or consent to the appointment of
any receiver, trustee or similar officer for all or a substantial part of his
property, or such receiver, trustee or similar officer shall be appointed
without the application or consent of Borrower and such appointment shall
continue undischarged for a period of twenty-four (24) hours, or (iv) institute
(by petition, application, answer, consent or otherwise) any bankruptcy,
insolvency, reorganization, arrangement, readjustment of debt, dissolution,
liquidation or similar proceeding under the laws of any jurisdiction or any such
proceeding shall be instituted (by petition, application or otherwise) against
Borrower and shall remain undismissed for a period of twenty-four (24) hours.

        Upon the occurrence of an Event of Default, the Lender may, at its
option, declare the entire principal balance owing hereunder immediately due and
payable, without further notice, demand or presentment, all of which are hereby
waived by the Borrower. Failure to exercise this option shall not

--------------------------------------------------------------------------------

constitute a waiver by the Lender of the right to exercise the same upon the
occurrence of any subsequent Event of Default.

        In the event default is made in the prompt payment of any amount when
due or declared due pursuant to this Promissory Note, and this Promissory Note
is placed in the hands of an attorney for collection or to defend or enforce any
of the legal holder's rights hereunder, or if the same is collected through any
judicial proceeding whatsoever, then Borrower, together with all other parties
liable for payment hereof, agrees to pay to the legal holder all professional
fees, together with all court costs and expenses incurred by such holder in
connection with such proceeding, except to the extent such obligations are
prohibited by law.

        Borrower hereby covenants and agrees to hold harmless and indemnify
Lender, upon demand by Lender, from and against any and all costs, expenses,
charges, taxes, penalties or other liability of any nature imposed on or
incurred by Lender relating to, resulting from or arising in connection with the
loan to Borrower evidenced hereby, including, without limitation, any and all
costs, expenses and charges of any nature relating to the imputation of interest
on amounts loaned to Borrower hereunder.

        Borrower hereby waives presentment and demand for payment, protest,
notice of protest and nonpayment or dishonor, notice of acceleration and notice
of intent to accelerate, diligence in collecting and grace, and consents to all
extensions, without notice for any period or periods of time and partial
payments, before or after maturity hereof, without prejudice to the rights of
the Lender arising hereunder.

        THIS NOTE, AND ALL OTHER DOCUMENTS EXECUTED IN CONNECTION HEREWITH,
REPRESENT THE FINAL AND ENTIRE AGREEMENT BETWEEN THE PARTIES PERTAINING TO THE
SUBJECT MATTER HEREOF, AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR,
SUBSEQUENT OR CONTEMPORANEOUS ORAL AGREEMENTS. THERE ARE NO ORAL AGREEMENTS
BETWEEN THE PARTIES PERTAINING TO THE SUBJECT MATTER HEREOF.

        This Note shall be governed by and construed in accordance with the laws
of the State of Nebraska.

        This Promissory Note and all provisions herein are binding upon Borrower
and his heirs, personal representatives, executors and assigns, and shall inure
to the benefit of Lender and its successors and assigns. Borrower shall not
assign any right or delegate any obligation arising hereunder without the prior
written consent of Lender. Lender does not by any act, delay, omission or
otherwise waive any of its rights or remedies, and no waiver of any kind
pertaining to the obligations arising hereunder shall be valid or enforceable
against Lender unless such waiver is in writing and signed by an authorized
representative of Lender.

--------------------------------------------------------------------------------

        IN WITNESS WHEREOF, the Borrower has executed and delivered this
Promissory Note on the date herein above first set forth.
