Item 2.  Acquisition or Disposition of Assets.

         On July 31, 1997, Transcrypt International, Inc. ("Transcrypt" or the
"Company") consummated the acquisition (the "Acquisition") of all of the
outstanding shares of capital stock and certain indebtedness of E.F. Johnson
Company, a Minnesota corporation ("EF Johnson"). The Company entered into and
consummated the following definitive agreements as of July 31, 1997: (i) a Stock
Purchase Agreement by and among EFJ Partners, EF Johnson, William Weksel and the
Company (the "Common Stock Purchase Agreement"); (ii) a Preferred Stock Purchase
Agreement between NorAm Energy Corp. ("NorAm") and the Company (the "Preferred
Stock Purchase Agreement"); (iii) a Series B Preferred Stock and Warrant
Purchase Agreement between Securicor Radiocoms Limited ("Securicor") and the
Company (the "Series B Preferred Stock Purchase Agreement"); and (iv) a
Registration Rights Agreement by and among NorAm, Intek Diversified Corporation
("Intek") (the parent of Securicor) and the Company (the "Registration Rights
Agreement"). The Company had previously announced, on June 12, 1997, a letter of
intent to acquire EF Johnson dated June 6, 1997, as amended on June 11, 1997
(the "Letter of Intent").

         Pursuant to the Common Stock Purchase Agreement, the Company acquired
from EFJ Partners all of the outstanding shares of Common Stock, $.01 par value,
of EF Johnson. At the closing, the Company discharged certain indebtedness of EF
Johnson, pursuant to the Common Stock Purchase Agreement, representing total
cash consideration of $436,000. Pursuant to the Preferred Stock Purchase
Agreement, the Company acquired from NorAm all of the outstanding shares of
Preferred Stock, $100 par value, of EF Johnson (together with the right to all
accrued and unpaid dividends thereon) in exchange for 457,856 newly issued
shares of Common Stock, $.01 par value, of the Company issued to NorAm with an
approximate market value of $5.5 million. In addition, NorAm agreed to cancel a
9.79% Senior Subordinated Note due July 31, 1997 of EF Johnson with a principal
amount of $10,000,000, and any accrued and unpaid interest thereon. Pursuant to
the Series B Preferred Stock Purchase Agreement, the Company acquired from
Securicor (i) all of the outstanding shares of Series I Class B Preferred Stock,
$.01 par value, of EF Johnson (together with the right to all accrued and unpaid
dividends thereon) and (ii) a warrant to purchase up to an aggregate of 291,790
shares of Common Stock of EF Johnson for an exercise price equal to the fair
market value of such Common Stock on the date the warrant is exercised, all in
exchange for 374,609 newly issued shares of Common Stock of the Company issued
to Intek with an approximate market value of $4.5 million. In addition, pursuant
to the Letter of Intent, the Company had previously delivered letters of credit
in the aggregate amount of $2,000,000 to support a surety bond issued by one 
of EF Johnson's bonding companies and to provide additional collateral under 
certain indebtedness of EF Johnson.

         The shares of Common Stock of the Company issued to NorAm and Intek
were exempt from registration under the Securities Act of 1933 in reliance upon
Section 4(2) of such Act as transactions by an issuer not involving any public
offering. Pursuant to the Registration Rights Agreement, the Company granted
certain piggyback and demand registration rights to NorAm and Intek with respect
to the aggregate 832,465 shares of Common Stock issued to such entities in
connection with the Acquisition (the "New Shares"). Under the piggyback
registration rights provisions, if the Company proposes to register any of its
securities under the Securities Act of 1933 (except for a registration on Forms
S-4 or S-8 or involving an issuance related to an exchange offer or offering
solely to existing



                                        1

<PAGE>   3

stockholders or employees of the Company), either for its own account or the
account of other securityholders, the holders of the New Shares will be entitled
to notice of such proposed registration and will be entitled to include their
shares therein; provided, however, among other conditions, that the underwriters
of such offering will have the right, subject to certain limitations, to limit
the number of such shares included in any such registration. Such piggyback
registration rights are effective immediately as to 416,232 of the New Shares
and are effective as to the remaining 416,233 of the New Shares beginning 180
days after the date of effectiveness of the Registration Rights Agreement, or
January 27, 1998. In addition, the holders of at least 66 2/3% of the New Shares
will be entitled to one demand registration by the Company beginning 180 days
after the date of effectiveness of the Registration Rights Agreement, subject
to, among other things, the right of the Company, under certain conditions, to
defer such registration. The holders of the New Shares have also agreed not to
dispose of any of the New Shares for a period of 180 days after the date of
effectiveness of the Registration Rights Agreement, except pursuant to a sale in
connection with the aforementioned registration rights.

         The cash consideration used by the Company in the Acquisition was
obtained from the proceeds of the Company's initial public offering in January
1997. Other than as described above, at the time of the Acquisition there were
no material relationships between any of the stockholders of EF Johnson and the
Company, any of the Company's affiliates, any director or officer of the Company
or any associate of any such director or officer. The Acquisition will be
accounted for under the purchase method of accounting.

         EF Johnson develops and manufactures wireless communications products
and systems for the land mobile radio market. The Company intends to continue
operating the business of EF Johnson and has announced a restructuring program
for EF Johnson, including a 25% reduction in EF Johnson's workforce, the
phase-out of low margin products and services, the consolidation of EF Johnson's
corporate headquarters with that of the Company, the elimination of duplicative
sales, marketing and personnel expenses with the Company and the implementation
of cash management policies and expense controls consistent with the Company's
standards.

Agreement, Preferred Stock Purchase Agreement, Series B Preferred Stock Purchase
Agreement and Registration Rights Agreement do not purport to be complete

there is no outstanding security of any kind convertible into or exchangeable
for such capital stock and (iii) there is no voting trust or other agreement or
understanding to which the Company is a party or is bound with respect to the

            3.2. CORPORATE ORGANIZATION OF THE COMPANY. The Company is a
corporation duly organized, validly existing and in good standing under the laws
of Minnesota, and has the requisite corporate power and authority to own, lease
or otherwise hold the properties and assets owned, leased and held by it and to
carry on the Business as currently conducted by it. The Company is duly
qualified to conduct business as a foreign corporation in every state of the
United States in which its ownership or lease of property or conduct of the
Business makes such qualification necessary, except for such states in which the
Company's failure to be so qualified would not have a material adverse effect on
the business, financial condition or results of operations of the Company and
the Subsidiaries, as hereinafter defined, taken as a whole (a "Material Adverse
Effect").

            3.3 SUBSIDIARIES. All of the Company's subsidiaries are as set forth

transactions contemplated hereby to be performed by Seller have been duly
authorized by all necessary partnership action on the part of Seller. This
Agreement has been duly executed and delivered by Seller and, assuming the due
execution and delivery of this Agreement by Buyer, constitutes a valid and
binding obligation of Seller, enforceable in accordance with its terms.

            3.5 ABSENCE OF CONFLICTS. Except as set forth on Schedule 3.5
hereto, the execution and delivery of this Agreement by Seller does not, and the
performance by Seller of the transactions contemplated hereby to be performed by
Seller will not, conflict with, or result in any violation of, or constitute a
default (with or without notice or lapse of time, or both) under, or give rise
to a right of termination, cancellation or acceleration of any obligation or
loss of a material benefit under, (i) any provision of the General Partnership
Agreement of EFJ Partners dated as of July 31, 1992 between William Weksel and
Robert Davies (the "Partnership Agreement"), the articles of incorporation, as

issued or applicable to Seller , the Company, or to any of their respective

terminations, cancellations, accelerations or losses which would not have a
Material Adverse Effect; provided, however, that Seller makes no representation
or warranty herein with respect to the effects of the performance of the
transactions contemplated hereby under any antitrust, trade regulation or
similar Law. No consent, approval, order or authorization of, or registration,
declaration or filing with, any Governmental Authority is required to be

as set forth on Schedule 3.5 hereto or (ii) such consents, approvals, orders or
authorizations which, if not obtained, or such registrations or filings which,
if not obtained or made, would not have a Material Adverse Effect.

                                      14

<PAGE>   15
asserted or unasserted, known or unknown and whether due or to become due),
damages, charges, Liens, deficiencies or expenses of any nature, including,
without limitation, reasonable attorneys' fees and expenses (all of which shall
be recoverable hereunder, net of any tax benefit to any Buyer Indemnified Party)
(collectively, "Damages") incurred by or assessed against any Buyer Indemnified
Party, and arising out of or resulting from:

                  (i) the inaccuracy of any representation or warranty made by
Seller pursuant to Section 3 hereof; or

                  (ii) the failure by Seller to perform or observe any term or

Parties for any and all Damages incurred by or assessed against any Seller

                  (b) the failure by Buyer to perform or observe any term or
provision of this Agreement or of any other document, Schedule or instrument
delivered in connection herewith; or

                  (c)   any liability of the Company or any of the Subsidiaries.

            9.4 NOTICE OF CLAIM. If any legal proceedings, claims or demands are
instituted or asserted in respect of which any of Buyer Indemnified Parties or
Seller Indemnified Parties may seek indemnification from another party hereto
pursuant to the provisions hereof (such legal proceedings, claims or demands
being referred to individually as a "Claim" and collectively as the "Claims"),
the indemnified party (after receipt by it of written notice of the commencement
or assertion of such Claim) shall promptly cause a written notice of such Claim
to be made to the indemnifying party (but the failure to give such notice shall
not relieve the indemnifying party of its indemnification obligation hereunder,
except to the extent of losses actually caused by such failure).

            9.5 ELECTION TO DEFEND CLAIM. Subject to the next sentence and
Section 9.6 hereof, the indemnifying party shall have the right, at its option
and expense, to assume the defense, settlement or other disposition
(collectively "Defense") of any Claim, provided that within ten (10) days of
receiving the notice with respect to such Claim pursuant to Section 9.4 hereof
(or within such shorter period of time as an answer or other responsive motion
may be required), the indemnifying party, by notice delivered to the indemnified
party, elects to assume such Defense and each indemnifying party acknowledges
its obligation hereunder to indemnify the indemnified party with respect to such
Claim. Notwithstanding the foregoing, the indemnifying party shall not have the

                                      15

<PAGE>   16
right to assume the Defense of any Claim if (a) representation of both the
indemnified and indemnifying parties by the same counsel would be inappropriate
due to actual or potential differing interests between them or (b) the
indemnified party determines in good faith that there is a significant
possibility that such Claim may materially and adversely affect it or its
Affiliates other than as a result of monetary damages.

            9.6 PROCEDURE FOR DEFENSE BY INDEMNIFYING PARTY. If the indemnifying
party has assumed the Defense of a Claim in accordance with Section 9.5 hereof,
then the following shall apply:

                  (a) the indemnified party shall have the right to participate
and assist in the Defense of such Claim and to employ its own counsel in
connection therewith;

                  (b) the indemnifying party shall not be liable to the
indemnified party for the fees or expenses of the indemnified party's counsel or
other expenses incurred by the indemnified party in connection with
participating in the Defense of such Claim, except that the indemnifying party
shall be liable for (i) any such fees and expenses incurred prior to the time
the indemnifying party assumed such Defense and (ii) the reasonable costs of
investigation and preparation incurred by the indemnified party;

                  (c) counsel used by the indemnifying party in connection with
the Defense of such Claim shall be reasonably satisfactory to the indemnified
party;

                  (d) the indemnified party shall not effect any compromise or
settlement of such Claim without the consent of the indemnifying party, which
consent shall not be unreasonably withheld; and

                  (e) the indemnifying party shall not effect any compromise or
settlement of such Claim without the consent of the indemnified party, which
consent shall not be unreasonably withheld.

            9.7 DEFENSE BY INDEMNIFIED PARTY. If the indemnifying party does not
assume the Defense of a Claim (whether because it elects not to or has no right
to), the indemnifying party shall have the right, at its sole cost and expense,
to participate in the Defense of such Claim and to employ its own counsel in
connection therewith; provided, however, the indemnified party may effect any
compromise or settlement of such Claim without the consent of the indemnifying
party.

            9.8 COOPERATION. The parties hereto shall cooperate to the fullest
extent possible in connection with any Claim in respect of which indemnification
is sought under this Agreement.

            9.9 LIMITATIONS ON INDEMNITY. The obligations of Seller pursuant to
Section 9.2(i) hereof shall arise only if the aggregate claims thereunder are in
excess of $50,000 and shall be limited to a total of claims thereunder not
exceeding $1 million in the aggregate, and Seller shall have no obligations
pursuant to such Section 9.2(i) with respect to any claim thereunder asserted by
any Buyer Indemnified Party after the first anniversary of the Closing Date.
Notwithstanding anything to the contrary contained in this Agreement, Seller
shall have no obligation pursuant to Section 9.2(i) hereof with respect to any
matter as to which (a) the Company has taken a reserve in

                                      16

<PAGE>   17
respect of the Interim Balance Sheet or since the date thereof, or (b) the
Company has changed its accounting principles or has applied accounting
principles in a manner inconsistent with the manner of application reflected in
the audited financial statements of the Company as of and for the years ended
December 31, 1996, 1995 and 1994, or (c) a reference is made on Schedule 9.9
hereto.

            9.10 ESCROW. William Weksel shall, upon receipt thereof, deposit
with an escrow agent mutually acceptable to William Weksel and Buyer, pursuant
to the terms of an escrow agreement in form and substance reasonably acceptable
to William Weksel and Buyer, the proceeds, if any, of the junior participation
of William Weksel in the advances, loans and other financial accommodations of
Congress Financial Corporation to the Company, when, as and if such proceeds are
paid to William Weksel. Any Buyer Indemnified Party shall be entitled to payment
from such escrowed proceeds of any amount due such Buyer Indemnified Party
pursuant to this Article IX and William Weksel shall give the escrow agent all
such notices as shall be necessary to permit such payment from such escrowed
proceeds. Subject to any Buyer Indemnified Party demand hereunder that may be
pending at such time, William Weksel shall be entitled to payment of all amounts
held in such escrow upon the first anniversary of the Closing Date.

            9.11 EXCLUSIVE REMEDY. Notwithstanding anything to the contrary
contained in this Agreement, the sole and exclusive remedy of Buyer and Seller,
or any other Buyer Indemnified Parties or Seller Indemnified Parties with
respect to any matter under or relating to this Agreement, including, without
limitation, any breach of any representation or warranty hereunder or pursuant
hereto shall be the remedy provided for in Sections 9.2 and 9.3 hereof, subject
to the limitations in Section 9.9 hereof.

                              PURCHASE AGREEMENT


            This Preferred Stock and Subordinated Note Purchase Agreement (this

Energy Corp., a Delaware corporation ("Seller"), and Transcrypt International,

                                  BACKGROUND

            WHEREAS, Seller owns 80,000 shares of the Preferred Stock, $100 par

            WHEREAS, Seller is the payee and holder of EFJ's 9.79% Senior
Subordinated Note dated July 31, 1992 in the principal amount of $10,000,000
(the "Note");

            WHEREAS, based upon the representations, covenants, agreements and
warranties herein made by Seller, and subject to the terms and conditions

unpaid interest thereon).

            2. CONSIDERATION. The total consideration to be paid for the Shares

any fractional shares of Transcrypt Common Stock resulting from such division

            3. REPRESENTATIONS AND WARRANTIES OF SELLER. Seller represents and
warrants to Buyer as follows:

            3.2. CORPORATE ORGANIZATION OF SELLER. Seller is a corporation duly
organized, validly existing and in good standing under the laws of the state of
its incorporation, and has the requisite corporate power and authority to own,

Agreement has been duly executed and delivered by Seller and, assuming the due
execution and delivery of this Agreement by Buyer, constitutes a valid and
binding obligation of Seller, enforceable in accordance with its terms.

            3.4 ABSENCE OF CONFLICTS. The execution and delivery of this
Agreement by Seller does not, and the performance by Seller of the transactions
contemplated hereby to be performed by Seller will not, conflict with, or result
in any violation of, or constitute a default (with or without notice or lapse of

Agreement has been duly executed and delivered by Buyer and, assuming the due
execution and delivery of this Agreement by Seller, constitutes a valid and
binding obligation of Buyer, enforceable in accordance with its terms.

            4.3 ABSENCE OF CONFLICTS. The execution and delivery of this
Agreement by Buyer does not, and the performance by Buyer of the transactions

any violation of, or constitute a default (with or without notice or lapse of
time, or both) under, (i) any provision of the certificate of incorporation or
bylaws of Buyer or any contract to which Buyer is a party, or (ii) any Permit of
any Governmental Authority, (iii) any Law of any Governmental Authority issued

partnership ("EFJ Partners"), and Buyer (the "Stock Purchase Agreement"), there
are no agreements between Buyer or any of its Affiliates, on the one hand, and
EFJ, EFJ Partners or any of their respective Affiliates, on the other hand, that
provide for the payment of sums of money or any other form of consideration
including, but not limited to, Transcrypt Common Stock, from Buyer or any of its
Affiliates to EFJ, EFJ Partners or any of their respective Affiliates.

            4.5 CERTAIN LIMITATIONS ON REPRESENTATIONS AND WARRANTIES. Buyer is

                      SERIES B PREFERRED STOCK AND WARRANT
                               PURCHASE AGREEMENT


               This Series B Preferred Stock and Warrant Purchase Agreement
(this "Agreement") is entered into this 31st day of July, 1997, by and between

Wales ("Seller"), and Transcrypt International, Inc., a Delaware corporation
("Buyer").


                                   BACKGROUND

               WHEREAS, Seller owns (i) 925,850 shares of Series I Class B
Preferred Stock, $.01 par value per share (the "Shares"), of E.F. Johnson
Company, a Minnesota corporation (the "Company"), constituting all of the issued
and outstanding shares of such Preferred Stock, and (ii) a warrant to purchase
up to an aggregate 291,790 shares of Common Stock, $.01 par value per share, of
the Company (the "Warrant"), issued pursuant to the Warrant Purchase Agreement,
dated as of March 14, 1995, among the Company, Securicor Communications Inc. and
the other parties thereto (the "Warrant Purchase Agreement");

               WHEREAS, Buyer wishes to purchase and acquire the Shares and the
Warrant from Seller; and

               WHEREAS, Seller wishes to sell and transfer the Shares and the
Warrant to Buyer;

               NOW, THEREFORE, in consideration of the foregoing and the mutual
promises and covenants set forth below, the parties hereto hereby agree as
follows:

               1. SALE AND PURCHASE OF SHARES AND WARRANT. Subject to the terms
and condi tions set forth in this Agreement, at the Closing (as defined in
Section 5.1 hereof) Seller shall (a) sell and transfer to Buyer, and Buyer shall
purchase and acquire from Seller, the Shares (together with Seller's right to
all accrued and unpaid dividends thereon) and the Warrant, and (b) assign to
Buyer all of Seller's rights in and to the Warrant Purchase Agreement.

               2. CONSIDERATION. The total consideration to be paid for the
Shares (together with Seller's right to all accrued and unpaid dividends
thereon) and the Warrant pursuant hereto is a number of whole shares of the
common stock, no par value, of Buyer ("Buyer Common Stock"), equal to the
quotient obtained by dividing (x) $4.5 million by (y) the average of the per
share closing prices for Buyer Common Stock on NASDAQ for the five consecutive
trading days at least one trading day immediately preceding the day of the
Closing, provided that any fractional shares of Buyer Common Stock resulting
from such division shall be rounded up to the nearest share, which
consideration, subject to the terms and conditions of this Agreement, shall be
payable by Buyer to Seller at the Closing as set forth in Section 5 hereof.

Buyer Indemnified Party, and shall reimburse Buyer Indemnified Parties for any

contingent or otherwise and whether asserted or unasserted, known or unknown and
whether due or to become due), damages, charges, liens, deficiencies or expenses

Parties or the Seller Indemnified Parties may seek indemnification from a party
hereto pursuant to the provisions hereof (such legal proceedings, claims or
demands being referred to individually as a "Claim" and collectively as the
"Claims"), the indemnified party (after receipt by it of written notice of the
commencement or assertion of such Claim) shall promptly cause a written notice
of such Claim to be made to the indemnifying party (but the failure to give such
notice shall not relieve the indemnifying party of its indemnification
obligation hereunder, except to the extent of losses actually caused by such
failure).

(collectively "Defense") of any Claim, provided that within ten (10) days of
receiving the notice with respect to such Claim pursuant to Section 9.4 hereof
(or within such shorter period of time as an answer or other responsive motion
may be required), the indemnifying party, by notice delivered to the indemnified
party, elects to assume such Defense. Notwithstanding the foregoing, the
indemnifying party shall not have the right to assume the Defense of any Claim
if the indemnified party determines in good faith that there is a significant
possibility that such Claim may materially and adversely affect it or its
Affiliates other than as a result of monetary damages.

<PAGE>   8
               9.6 PROCEDURE FOR DEFENSE BY INDEMNIFYING PARTY. If the
indemnifying party has assumed the Defense of a Claim in accordance with Section
9.5 hereof, then the following shall apply:

                        (a) the indemnified party shall have the right to
participate and assist in the Defense of such Claim and to employ its own
counsel in connection therewith;

                        (b) the indemnifying party shall not be liable to the
indemnified party for the fees or expenses of the indemnified party's counsel or
other expenses incurred by the indemnified party in connection with
participating in the Defense of such Claim, except that the indemnifying party
shall be liable for (i) any such fees and expenses incurred prior to the time
the indemnifying party assumed such Defense and (ii) the reasonable costs of
investigation and preparation incurred by the indemnified party;

                        (c) counsel used by the indemnifying party in connection
with the Defense of such Claim shall be reasonably satisfactory to the
indemnified party;

                        (d) the indemnified party shall not effect any
compromise or settlement of such Claim without the consent of the indemnifying
party; and

                        (e) the indemnifying party shall not effect any
compromise or settlement of such Claim without the consent of the indemnified
party if the compromise or settlement involves matters other than the payment by
the indemnifying party of money damages, in which event such consent shall not
be unreasonably withheld.

               9.7 DEFENSE BY INDEMNIFIED PARTY. If the indemnifying party does
not assume the Defense of a Claim (whether because it elects not to or has no
right to), the indemnifying party shall have the right, at its sole cost and
expense, to participate in the Defense of such Claim and to employ its own
counsel in connection therewith; provided, however, the indemnified party may
not effect any compromise or settlement of such Claim without the consent of the
indemnifying party, which consent shall not be unreasonably withheld.

               9.8 COOPERATION. The parties hereto shall cooperate to the
fullest extent possible in connection with any Claim in respect of which
indemnification is sought under this Agreement.

               9.9 EXCLUSIVE REMEDY. Notwithstanding anything to the contrary
contained in this Agreement, the sole and exclusive remedy of Buyer, or any
other Buyer Indemnified Parties with respect to any matter under or relating to
this Agreement, including, without limitation, any breach of any representation
or warranty hereunder or pursuant hereto shall be the remedy provided for in
Sections 9.2 and 9.3 hereof.

<PAGE>   5
public offering of Common Stock for the Company's own account (other than
pursuant to a registration statement on Form S-4 or Form S-8 or any successor
forms, or filed in connection with an exchange offer or an offering of
securities solely to existing stockholders or employees of the Company) or for
the account of any holder of Common Stock and on a form and in a manner that
would permit registration of Registrable Securities for sale to the public under
the Securities Act, the Company shall (i) give written notice at least 20
Business Days prior to the filing thereof to Stockholders, specifying the
approximate date on which the Company proposes to file such Registration
Statement, the number and class of securities so proposed to be registered, any
proposed means of distribution of such securities, and a good faith estimate by
the Company of the proposed maximum offering price thereof, as such price is
proposed to appear on the facing page of such Registration Statement, and
advising Stockholders of its right to request that any or all of the Registrable
Securities then held by Stockholders included among the securities to be covered
thereby and (ii) at the written request of Stockholders given to the Company
within 15 calendar days after the Stockholders' receipt of written notice from
the Company, include among the securities covered by such registration statement
the number of Registrable Securities which Stockholders shall have requested to
be so included (subject, however, to reduction in accordance with paragraph (b)
of this Section).

                      b. If a Stockholder desires to participate in an offering
pursuant to Section 4(a), it may include Registrable Securities in any
Registration Statement relating to such offering to the extent that the
inclusion of such Registrable Securities shall not reduce the number of shares
of Company Common Stock to be offered and sold by the Company. If the lead
managing underwriter selected by the Company for an underwritten offering
pursuant to Section 4(a) determines that marketing factors require a limitation
on the number of shares of Registrable Securities to be offered and sold by a
Stockholder in such offering, there shall be included in the offering only that
number of shares of Registrable Securities, if any, that such lead managing
underwriter reasonably in good faith believes will not jeopardize the success of
the offering of all the shares of Company Common Stock that the Company desires
to sell for its own account. In such event and provided the lead managing
underwriter has so notified the Company in writing, the shares of Company Common
Stock to be included in such offering shall consist of (i) first, the securities
the Company proposes to sell, and (ii) second, the number, if any, of
Registrable Securities requested to be included in such registration that, in
the opinion of such lead managing underwriter can be sold without jeopardizing
the success of the offering of all the securities that the Company desires to
sell for its own account. To facilitate the allocation of shares in accordance
with this provision, the Company or the underwriters may round the number of
shares allocated to a Stockholder to the nearest 100 shares.

                      c. Nothing in this Section 4 shall create any liability on
the part of the Company to Stockholders if the Company for any reason should
decide not to file a registration statement proposed to be filed under Section
4(a) or to withdraw such registration statement subsequent to its filing,
regardless of any action whatsoever that Stockholders may have taken, whether as
a result of the issuance by the Company of any notice hereunder or otherwise.

<PAGE>   6



                      d. A request by a Stockholder to include Registrable
Securities in a proposed underwritten offering pursuant to Section 4(a) shall
not be deemed to be a request for a demand registration pursuant to Section 5.

               5. Demand Registration Rights. a. Upon the written request of a
Stockholder (the "Requesting Stockholder") during the Effective Period that the
Company effect the registration with the SEC under and in accordance with the
provisions of the Securities Act of not less than 662/3% of such Requesting
Stockholder's Registrable Securities (which written request shall specify the
aggregate number of shares of Registrable Securities requested to be registered
and the means of distribution), the Company will use its best efforts to file a
Registration Statement covering Requesting Stockholder's Registrable Securities
requested to be registered as soon as practicable after receipt of such request;
provided, however, that the Company shall not be required to take any action
pursuant to this Section 5:

                      (1) if prior to the date of such request the Company shall
        have effected one registration pursuant to this Section 5 for such
        stockholder;

                      (2) if the Company shall at the time have effective a
        Shelf Registration pursuant to which the Requesting Stockholder could
        effect the disposition of such Requesting Stockholder's Registrable
        Securities in the manner requested;

                      (3)    during the pendency of any Blackout Period;

                      (4) in any particular jurisdiction in which the Company
        would be required to execute a general consent to service of process in
        effecting such registration, qualification or compliance unless the
        Company is already subject to service in such jurisdiction and except as
        may be required by the Securities Act; or

                      (5) if the Company shall furnish to such Requesting
        Stockholder a certificate signed by the President of the Company stating
        that in the good faith judgment of the Board of Directors it would be
        seriously detrimental to the Company or its stockholders for a
        Registration Statement to be filed in the near future, then the
        Company's obligation to use its best efforts to register, qualify or
        comply under this Section 5 shall be deferred for a period not to exceed
        ninety (90) days from the date of receipt of the original written
        request from the Requesting Stockholder;

provided, however, that the Company shall be permitted to satisfy its
obligations under this Section 5(a) by amending (to the extent permitted by
applicable law) within 30 Business Days after a written request for
registration, any Registration Statement previously filed by the Company under
the Securities Act so that such Registration Statement (as amended) shall permit
the disposition (in accordance with the intended methods of disposition
specified as aforesaid) of all of the Registrable Securities for which a demand
for registration has been made under this Section 5(a). If the

                                        6

<PAGE>   7
Company shall so amend a previously filed Registration Statement, it shall be
deemed to have effected a registration for purposes of this Section 5.

                      b. Requesting Stockholder may distribute the Registrable
Securities covered by such request by means of an underwritten offering or any
other means, as determined by such Requesting Stockholder.

                      c. Except for a Registration Statement subject to Section
5(d), a registration requested pursuant to this Section 5 shall not be deemed to
be effected for purposes of this Section 5 if it has not been declared effective
by the SEC or become effective in accordance with the Securities Act and the
rules and regulations thereunder.

                      d. Requesting Stockholder may, at any time prior to the
effective date of the Registration Statement relating to such registration,
revoke such request by providing a written notice to the Company revoking such
request. If a Registration Statement is so revoked, the Requesting Stockholder
shall reimburse the Company for all its out-of-pocket expenses and fees incurred
in the preparation, filing and processing of the Registration Statement.

                      e. Without the prior written consent of Stockholders, the
Company will not include any securities which are not Registrable Securities in
any Registration Statement filed pursuant to a demand made under this Section 5.

               6. Underwriting. In the event that a registration pursuant to
Section 5 is for a registered public offering involving an underwriting, the
Company shall so advise the Stockholders. In such event, the right of
Stockholders to participate in such registration shall be conditioned upon
Stockholders' participating in the underwriting arrangements required by this
Section 6, and the inclusion of such Stockholders' Registrable Securities in the
underwriting to the extent requested shall be limited to the extent provided
herein.

               The Company shall (together with all holders proposing to
distribute their securities through such underwriting) enter into an
underwriting agreement in customary form with the managing underwriters selected
for such underwriting by the Company.

               If a Stockholder disapproves of the terms of the underwriting,
such Stockholder may elect to withdraw therefrom by written notice to the
Company and the managing underwriter and such registration shall not be deemed
to be a registration pursuant to Section 5 hereof. The Registrable Securities,
and/or other securities so withdrawn shall also be withdrawn from registration,
and such securities shall not be transferred in a public distribution prior to
one hundred eighty (180) days after the effective date of such registration, or
such other shorter period of time as the underwriters may require.

               7. Blackout Periods; Holdback. a. If the Company determines in
good faith that the registration and distribution of Registrable Securities (i)
would materially impede, delay,

                                        7

<PAGE>   8
interfere with or otherwise adversely affect any pending financing, registration
of securities, acquisition, corporate reorganization or other significant
transaction involving the Company or (ii) would require disclosure of non-public
material information that the Company has a bona fide business purpose for
preserving as confidential, as determined by the Board of Directors of the
Company in good faith, the Company shall promptly give Stockholders notice of
such determination and shall be entitled to postpone the filing or effectiveness
of a Registration Statement for the shortest period of time reasonably required,
but in any event not to exceed 180 days with respect to matters covered by
clause (i) above, and not to exceed 90 days with respect to matters covered by
clause (ii) above (a "Blackout Period"); provided, that a Blackout Period with
respect to a registration of securities proposed by the Company may, at the
election of the Company, commence on the date that is 30 calendar days prior to
the date the Company in good faith estimates will be the date of filing of, and
end no later than the date, following the effective date of such registration,
specified in the form of underwriting agreement relating to such registration
during which the Company shall be prohibited from selling, offering or otherwise
disposing of Common Stock, but in no event to exceed 180 days; provided further,
that the Company shall not obtain any deferral under this Section 7(a) more than
twice in any twelve-month period, other than normal deferrals required prior to
the public release of quarterly financial results of the Company. The Company
shall promptly notify Stockholders of the expiration or earlier termination of a
Blackout Period.

                      b. Each Stockholder agrees by acquisition of the
Registrable Securities, if so requested in writing by the Company or any
managing underwriter, not to effect any public sale or distribution, make any
short sale of, loan, grant any option for the purchase of or otherwise dispose
of any of such securities or Related Securities during the seven days prior to
and the 180 days after the effective time of any underwritten registration by
the Company (either for its own account, or for the benefit of a Stockholder, in
each case as to which a Stockholder is entitled to request to be included
pursuant to Section 4) has become effective or such period of time shorter than
180 days that is sufficient and appropriate, in the prior written opinion of the
Company or the managing underwriter, in order to complete the sale and
distribution of securities included in such registration.

               8. Registration Procedures. If and whenever the Company is
required to use reasonable best efforts to effect or cause the registration of
any Registrable Securities under the Securities Act as provided in this
Agreement, the Company will:

                      a. prepare and file with the SEC a Registration Statement
with respect to such Registrable Securities on any form for which the Company
then qualifies or which counsel for the Company shall deem appropriate, and
which form shall be available for the sale of the Registrable Securities in
accordance with the intended methods of distribution thereof (including, if so
requested by a Stockholder, distributions under Rule 415 under the Securities
Act pursuant to a Shelf Registration Statement), and use its reasonable best
efforts to cause such Registration Statement to become and remain effective;


                                        8

<PAGE>   9
                      b. prepare and file with the SEC amendments and
post-effective amendments to such Registration Statement (including any Shelf
Registration referred to in Section 5(a)) and such amendments and supplements to
the Prospectus used in connection therewith as may be necessary to maintain the
effectiveness of such registration or as may be required by the rules,
regulations or instructions applicable to the registration form utilized by the
Company or by the Securities Act or rules and regulations thereunder necessary
to keep such Registration Statement effective (i) in the case of a firm
commitment underwritten public offering, until each underwriter has completed
the distribution of all securities purchased by it and (ii) in the case of any
other registration, for up to 90 days (or longer period in the event of a
Registration Hold Period during such offering, as provided in this Section 8)
and cause the Prospectus as so supplemented to be filed pursuant to Rule 424
under the Securities Act, and to otherwise comply with the provisions of the
Securities Act with respect to the disposition of all securities covered by such
Registration Statement until the earlier of (x) such 90th day (or longer period)
and (y) until the distribution described in the Registration Statement has been
completed;

                      c. furnish to Stockholders such reasonable number of
copies of such Registration Statement and of each amendment and post-effective
amendment thereto, any Prospectus or Prospectus supplement and such other
documents as Stockholders may reasonably request in writing in order to
facilitate the disposition of the Registrable Securities by Stockholder (the
Company hereby consenting to the use (subject to the limitations set forth in
the last paragraph of this Section 8) of the Prospectus or any amendment or
supplement thereto in connection with such disposition);

                      d. use its best efforts to register or qualify such
Registrable Securities covered by such Registration Statement under such other
securities or blue sky laws of such jurisdictions as Stockholder shall
reasonably request in writing;

                      e. notify Stockholders, at any time when a Prospectus
relating to any Registrable Securities is required to be delivered under the
Securities Act within the appropriate period mentioned in Section 8(b), of the
Company's becoming aware that the Prospectus included in such Registration
Statement, as then in effect, includes an untrue statement of a material fact or
omits to state a material fact required to be stated therein or necessary to
make the statements therein not misleading in light of the circumstances then
existing (the period during which Stockholder is required to refrain from
effecting public sales or distributions in such case being referred to as a
"Section 8(e) Period"), and prepare and furnish to Stockholders a reasonable
number of copies of an amendment to such Registration Statement or related
Prospectus as may be necessary so that, as thereafter delivered to the
purchasers of such Registrable Securities, such Prospectus shall not include an
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary to make the statements therein not misleading in
light of the circumstances then existing, and the time during which such
Registration Statement shall remain effective pursuant to Section 8(b) shall be
extended by the number of days in the Section 8(e) Period;


                                        9

<PAGE>   10
                      f. notify Stockholders or Stockholders' counsel (if
Registrable Securities are covered by such Registration Statement) at any time,

                             (1) when the Prospectus or any Prospectus
        supplement or post-effective amendment has been filed, and, with
        respect to the Registration Statement or any post-effective amendment,
        when the same has become effective;

                             (2) of any request by the SEC for amendments or
        supplements to the Registration Statement or the Prospectus or for
        additional information;

                             (3) of the issuance by the SEC of any stop order of
        which the Company or its counsel is aware or should be aware suspending
        the effectiveness of the Registration Statement or any order preventing
        the use of a related Prospectus, or the initiation or any threats of any
        proceedings for such purposes; and

                             (4) of the receipt by the Company of any written
        notification of the suspension of the qualification of any of the
        Registrable Securities for sale in any jurisdiction or the initiation or
        any threats of any proceeding for that purpose.

                      g. otherwise use its reasonable best efforts to comply
with all applicable rules and regulations of the SEC, and make available to its
stockholders an earnings statement which shall satisfy the provisions of Section
11(a) of the Securities Act, provided that the Company shall be deemed to have
complied with this paragraph if it has complied with Rule 158 under the
Securities Act;

                      h. use its reasonable best efforts to cause all such
Registrable Securities to be listed on any securities exchange or automated
quotation system on which the Common Stock is then listed, if such Registrable
Securities are not already so listed and if such listing is then permitted under
the rules of such exchange or automated quotation system, and to provide a
transfer agent and registrar for such Registrable Securities covered by such
Registration Statement no later than the effective date of such Registration
Statement;

                      i. cooperate with Stockholders (if Registrable Securities
are covered by such Registration Statement) and the managing underwriter or
underwriters or agents, if any, to facilitate the timely preparation and
delivery of certificates (not bearing any restrictive legends) representing the
securities to be sold under such Registration Statement, and enable such
securities to be in such denominations and registered in such names as the
managing underwriter or underwriters or agents, if any, or Stockholder may
request;

                      j. if reasonably requested by the managing underwriter or
underwriters (if Registrable Securities are being sold in connection with an
underwritten offering), incorporate in a Prospectus supplement or post-effective
amendment such information as the managing underwriters agree should be included
therein relating to the plan of distribution with respect to such

                                       10

<PAGE>   11
Registrable Securities, including, without limitation, information with respect
to the principal amount of Registrable Securities being sold to such
underwriters, the purchase price being paid therefor by such underwriters and
with respect to any other terms of the underwritten offering of the Registrable
Securities to be sold in such offering and make all required filings of such
Prospectus supplement or post-effective amendment as promptly as practicable
upon being notified of the matters to be incorporated in such Prospectus
supplement or post-effective amendment;

                      k. provide Stockholders (if Registrable Securities are
included in such Registration Statement), any underwriter participating in any
disposition pursuant to such Registration Statement and any attorney, accountant
or other agent retained by Stockholder or underwriter (collectively, the
"Inspectors") with reasonable access during normal business hours to appropriate
officers of the Company and the Company's subsidiaries to ask questions and to
obtain information reasonably requested by any such Inspector and make available
for inspection all financial and other records and other information, pertinent
corporation documents and properties of any of the Company and its subsidiaries
and affiliates (collectively, the "Records"), as shall be reasonably necessary
to enable them to exercise their due diligence responsibility; provided,
however, that the Records that the Company determines, in good faith, to be
confidential and which it notifies the Inspectors in writing are confidential
shall not be disclosed to any Inspector unless such Inspector signs or is
otherwise bound by a confidentiality agreement reasonably satisfactory to the
Company; and

                      l. in the event of the issuance of any stop order of which
the Company or its counsel is aware or should be aware suspending the
effectiveness of the Registration Statement or of any order suspending or
preventing the use of any related Prospectus or suspending the qualification of
any Registrable Securities included in the Registration Statement for sale in
any jurisdiction, the Company will use its best efforts promptly to obtain its
withdrawal; and the period for which the Registration Statement shall be kept
effective shall be extended by a number of days equal to the number of days
between the issuance and withdrawal of any stop orders (a "Section 8(m)
Period").

               The Company may require Stockholders (with respect to Registrable
Securities as to which any registration is being effected) to furnish the
Company with such information regarding Stockholders and pertinent to the
disclosure requirements relating to the registration and the distribution of
such securities as the Company may from time to time reasonably request and as
shall be required by law or by the SEC in connection with any registration.

               Stockholders shall, upon receipt of any notice from the Company
of the happening of any event of the kind described in Sections 8(e) or 8(m),
forthwith discontinue disposition of Registrable Securities pursuant to the
Prospectus or Registration Statement covering such Registrable Securities until
Stockholders' receipt of the copies of the supplemented or amended Prospectus
contemplated by Section 8(e) or the withdrawal of any stop order contemplated by
Section 8(m), and, if so directed by the Company, Stockholders will deliver to
the Company all

                                       11

<PAGE>   12
copies, other than permanent file copies then in Stockholders' possession, of
the Prospectus covering such Registrable Securities at the time of receipt of
such notice.

               9. Registration Expenses. The Company will pay all Registration
Expenses incurred in connection with all registrations of registrable Securities
pursuant to Sections 4 and 5, and Stockholders shall pay (x) any fees or
disbursements of Counsel to Stockholder and (y) all underwriting discounts and
commissions and transfer taxes, if any, and documentary stamp taxes, if any,
relating to the sale or disposition of Stockholders' Registrable Securities
pursuant to the Registration Statement.

               10. Reports Under the Exchange Act. The Company shall:

                      a. use its best efforts to file with the SEC in a timely
manner all reports and other documents required of the Company under the
Exchange Act; and

                      b. furnish to Stockholders, during the Effective Period,
forthwith upon written request (i) a written statement by the Company that it
has complied with the current public information and reporting requirements of
Rule 144 under the Securities Act and the Exchange Act and (ii) a copy of the
most recent annual or quarterly report of the Company and such other reports and
documents so filed by the Company with the SEC under the Exchange Act.

               11.    Indemnification; Contribution.

                      a. Indemnification by the Company. The Company shall
indemnify and hold harmless Stockholders, their respective officers, directors,
agents, trustees, stockholders and each Person who controls Stockholder (within
the meaning of Section 15 of the Securities act or Section 20 of the Exchange
Act), against all losses, claims, damages, liabilities and expenses (including
reasonable attorneys' fees, disbursements and expenses, as incurred) incurred by
such party pursuant to any actual or threatened action, suit, proceeding or
investigation arising out of or based upon any untrue or alleged untrue
statement of a material fact contained in the Registration Statement, any
Prospectus or preliminary Prospectus, or any amendment or supplement to any of
the foregoing or any omission or alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein
(in the case of a Prospectus, or a preliminary Prospectus, in light of the
circumstances then existing) not misleading, except in each case insofar as the
same arise out of or are based upon any such untrue statement or omission made
in reliance on and in conformity with information with respect to such
indemnified party furnished in writing to the Company by such indemnified party
or its counsel expressly for use therein. In connection with an underwritten
offering, the Company will indemnify the underwriters thereof, their officers,
directors, agents, trustees, stockholders and each Person who controls such
underwriters (within the meaning of Section 15 of the Securities Act or Section
20 of the Exchange Act) to the same extent as provided above with respect to the
indemnification of Stockholder. Notwithstanding the foregoing provisions of this
Section 11(a), the Company will not be liable to any Person who participates as
an underwriter in the offering or sale of Registrable Securities or any other
Person,

                                       12

<PAGE>   13
if any, who controls such underwriter (within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act), under the indemnity agreement
in this Section 11(a) for any such loss, claim, damage, liability (or action or
proceeding in respect thereof) or expense that arises out of such Person's
failure to send or deliver a copy of the final Prospectus to the Person
asserting an untrue statement or alleged untrue statement or omission or alleged
omission at or prior to the written confirmation of the sale of the Registrable
Securities to such Person if such statement or omission was corrected in such
final Prospectus and the Company has previously furnished copies thereof to
Stockholder or other Person in accordance with this Agreement.

                      b. Indemnification by Stockholders. In connection with any
Registration Statement filed pursuant hereto, each Stockholder will furnish to
the Company in writing such information with respect to such Stockholder,
including the name, address and the amount of Registrable Securities held by
such Stockholder, as the Company reasonably requests, and as shall be required
by law or by the SEC in connection with any registration, for use in such
Registration Statement or the related Prospectus and indemnify and hold harmless
the Company, or any underwriter, as the case may be, and their respective
directors, officers, agents, trustees, stockholders and controlling Persons
(within the meaning of Section 15 of the Securities Act or Section 20 of the
Exchange Act), against any losses, claims, damages, liabilities and expenses
(including reasonable attorneys' fees, disbursements and expenses, as incurred),
incurred by such party pursuant to any actual or threatened action, suit,
proceeding or investigation arising out of or based upon any untrue or alleged
untrue statement of a material fact contained in, or any omission or alleged
omission or a material fact required to be stated in such Registration
Statement, Prospectus or preliminary Prospectus or any amendment or supplement
to any of the foregoing or necessary to make the statements therein (in case of
Prospectus or preliminary Prospectus, in the light of the circumstances then
existing) not misleading, but only to the extent that any such untrue statement
or omission is made in reliance on and in conformity with information with
respect to such Stockholder furnished in writing to the Company by such
Stockholder or its counsel specifically for inclusion therein or preparation
thereby; provided, however, that the liability of such Stockholder hereunder
shall be limited to the proportion of any such loss, claim, damage, liability or
expense that is equal to the proportion that the gross proceeds from the sale of
shares sold by such Stockholder under such registration statement bears to the
total gross proceeds from the sale of all securities sold thereunder, but not in
any event to exceed the gross proceeds received by such Stockholder from the
sale of Registrable Securities covered by such Registration Statement, unless
such liability arises out of or is based on willful misconduct of such
Stockholder.

                      c. Conduct of Indemnification Proceedings. Any Person
entitled to indemnification hereunder shall give prompt written notice to the
indemnifying party after the receipt by such indemnified party of any written
notice of the commencement of any action, suit, proceeding or investigation or
threat thereof made in writing for which such indemnified party may claim
indemnification or contribution pursuant to this Agreement (provided that
failure to give such notification shall not affect the obligations of the
indemnifying party pursuant to this Section 11 except to the extent the
indemnifying party shall have been actually prejudiced as a result of such
failure). If any such action shall be brought against any indemnified party and
it shall promptly

                                       13

<PAGE>   14
notify in writing the indemnifying party of the commencement thereof, the
indemnifying party shall be entitled to participate therein and, to the extent
that it shall wish, jointly with any other indemnifying party similarly
notified, to assume the defense thereof, with counsel reasonably satisfactory to
such indemnified party, and after prompt written notice from the indemnifying
party to such indemnified party of its election so to assume the defense
thereof, the indemnifying party shall not be liable to such indemnified party
under these indemnification provisions for any legal expenses of other counsel
or any other expenses, in each case subsequently incurred by such indemnified
party, in connection with the defense thereof other than reasonable costs of
investigation, unless in the reasonable judgment of any indemnified party a
conflict of interest is likely to exist, based on the written opinion of
counsel, between such indemnified party and any other of such indemnified
parties with respect to such claim, in which event the indemnifying party shall
not be liable for the fees and expenses of (i) more than one counsel for
Stockholder, (ii) more than one counsel for the underwriters or (iii) more than
one counsel for the Company in connection with any one action or separate but
similar or related actions. An indemnifying party who is not entitled to, or
elects not to, assume the defense of a claim will not be obligated to pay the
fees and expenses of more than one counsel for all parties indemnified by such
indemnifying party with respect to such claims, unless in the reasonable
judgment of any indemnified party based on the written opinion of counsel a
conflict of interest may exist between such indemnified party and any other of
such indemnified parties with respect to such claim, in which event the
indemnifying party shall be obligated to pay the fees and expenses of such
additional counsel or counsels. No indemnifying party, in defense of any such
action, suit, proceeding or investigation, shall, except with the written
consent of each indemnified party, consent to the entry of any judgment or entry
into any settlement which does not include as an unconditional term thereof the
giving by the claimant or plaintiff to such indemnified party of a release from
all liability in respect to such action, suit, proceeding or investigation to
the extent the same is covered by the indemnity obligation set forth in this
Section 11. No indemnified party shall consent to entry of any judgment or enter
into any settlement without the written consent of each indemnifying party.

                      d. Contribution. If the indemnification from the
indemnifying party provided for in this Section 11 is unavailable to an
indemnified party hereunder in respect of any losses, claims, damages,
liabilities or expenses referred to herein, then the indemnifying party, in lieu
of indemnifying such indemnified party, shall contribute to the amount paid or
payable by such indemnified party as a result of such losses, claims, damages,
liabilities and expenses in such proportion as is appropriate to reflect the
relative fault of the indemnifying party and indemnified party in connection
with the actions which resulted in such losses, claims, damages, liabilities and
expenses, as well as any other relevant equitable considerations; provided,
however, that the liability of each Stockholder hereunder shall be limited to
the proportion of any such loss, claim, damage, liability or expense that is
equal to the proportion that the gross proceeds from the sale of shares sold by
such Stockholder under such Registration Statement bears to the total gross
proceeds from the sale of all securities sold thereunder, but not in any event
to exceed the net proceeds received by Stockholder from the sale of Registrable
Securities covered by such Registration Statement. The relative fault of such
indemnifying party and indemnified party shall be determined by reference to,
among other things, whether any action in question, including any untrue or
alleged untrue statement

                                       14

<PAGE>   15
of a material fact or omission or alleged omission to state a material fact, has
been made by, or relates to information supplied by, such indemnifying party or
indemnified party, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such action. The amount paid
or payable by a party as a result of the losses, claims, damages, liabilities
and expenses referred to above shall be deemed to include, subject to the
limitations set forth in Section 11(c), any legal and other fees and expenses
reasonably incurred by such indemnified party in connection with any
investigation or proceeding.

HEADLINE: Transcrypt International Announces Consummation of Agreement to
Acquire E.F. Johnson. Jeff Fuller to Become President and CEO of Transcrypt.

DATELINE: LINCOLN, Neb., July 31

BODY:

         Transcrypt International, Inc., (Nasdaq: TRII) today announced that it
has consummated a definitive agreement to acquire all of the outstanding shares
of Waseca, Minnesota based E.F. Johnson Company (EFJ). Johnson develops and
manufactures wireless communications products and systems to the land mobile
radio (LMR) market. EFJ has incurred losses and encountered cash flow
difficulties recently. The privately-held company had 1996 revenues of $79.3
million and losses of $26.5 million including a $13.5 million non recurring
charge. EFJ's unaudited financials through June 30, 1997 showed revenues of
$35.9 million and losses of $5.3 million for the six month period. Transcrypt
has prepared a restructuring plan for EFJ which includes a working capital
infusion, corporate restructuring and the introduction of a complete line of
APCO 25 digital radio products including; mobiles, base stations, portables and
infrastructure. Transcrypt cannot, however, give any assurances on how quickly
it can implement these changes.

         Consideration for the purchase of preferred stock totaled approximately
$12.4 million, consisting of 832,465 shares of Transcrypt Common Stock, valued
at $10 million, $436,000 and a $2 million Letter of Credit that was previously
provided to EFJ. Transcrypt further assumed EFJ bank debt of approximately $13
million. The definitive agreement reflects a significant decrease in the
purchase price since the June 6, 1997 Letter of Intent based upon, among other
things, the losses described above.

         Transcrypt also announced a new management structure for merger
integration whereby Jeff Fuller, Transcrypt's current President and Chief
Operating Officer will become the President and Chief Executive Officer upon
completion of the deal.

         According to John Connor, Transcrypt's Chairman, "This acquisition,
following Transcrypt's January IPO, is in step with our long-term strategy to
provide secure wireless communication products worldwide. E.F. Johnson brings
over 75 years of experience in the LMR market and a client base which is well
serviced in both domestic and international markets by over 800
distributorships. EFJ's strong South American presence complements Transcrypt's
existing penetration in overseas markets." Connor will continue as Chairman and
will focus on capital markets, mergers and acquisitions and Board activities.

         Fuller commented, "This vertical acquisition enhances our existing
products by adding the design and manufacturing of Radio Frequency and trunking
systems to TRII while broadening our current markets and distribution. As the
former VP of Marketing and Sales at E.F. Johnson, I am well acquainted with
Johnson's products, manufacturing strengths and corporate culture. I am very
pleased to have Scott and Fred join the new company and I look forward to once
again

working with E.F. Johnson's talented work force."

         Fuller's management team includes two former executives from EFJ. Mr.
Scott Bocklund, EFJ's former COO moves up to become TRII's Senior Vice President
of Finance and CFO. In addition, Mr. Fred Hamer, EFJ's former Vice President of
Sales becomes TRII's Vice President International. Fuller's team will also
include Eric Baumann as Vice President of North American, Bill Fox, a recent
addition as Senior Vice President of Sales and Business Development, Rebecca
Schultz as Corporate Secretary and Treasurer, Mike Wallace as Vice President of
Operations and Joel Young, as Vice President of Engineering and Marketing. "We
believe this acquisition, which was closed on July 31, 1997, will enhance
Transcrypt's ability to continue its growth and provide long-term returns to its
shareholders," according to Connor.

         Transcrypt International, Inc., based in Lincoln, Nebraska designs and
manufactures specialized scrambling and encryption devices which prevent the
unauthorized interception of sensitive voice and data communications for both
analog and digital transmissions. Transcrypt has recently launched a new line of
digital APCO 25 radios for public safety use that are also compatible with
existing analog systems. Transcrypt provides land mobile radio, telephony
(including cellular and wireless telephone) and data security products to
government agencies and corporations in 108 countries and all 50 states.

HEADLINE: Transcrypt International Announces E.F. Johnson Company Restructuring
Plan

DATELINE: LINCOLN, Neb., Aug. 6

BODY:

         Transcrypt International, Inc., (Nasdaq: TRII) today announced a
restructuring plan involving its new subsidiary, E.F. Johnson Company (EFJ)
which it acquired on July 31, 1997, which has recently incurred operating losses
and cash flow difficulties. EFJ develops and manufactures wireless
communications products and systems for the land mobile radio (LMR) market.

         Jeff Fuller, President and CEO said that the restructuring program will
be implemented immediately and will include: a 25% reduction of EFJ workforce,
the phase-out of low margin products and services, the consolidation of
corporate headquarters, the elimination of duplicative sales, marketing and
personnel expenses and the implementation of cash management policies and
expense controls consistent with Transcrypt standards. Mr. Fuller stated, 
"Transcrypt is focused on restructuring EFJ for current and future levels of
business, and we are confident that our plan will yield immediate results."

         The Company announced that approximately 25% of the 550 EFJ employees
in Burnsville and Waseca, Minnesota have received notices that their jobs are
being eliminated. These terminations were made effective today and included
severance payments under the EFJ Severance Policy Program.

         Scott Bocklund, Senior Vice President of Finance and CFO, stated
"Transcrypt has invested $6 million into EFJ to fund severance programs,
cancellation payments for duplicative expenses and to reduce accounts payable.
These programs will allow EFJ to resume shipping on a timely schedule and reduce
operating losses."

         EFJ's corporate offices will be consolidated at Transcrypt's Lincoln,
Nebraska headquarters. The company will continue to have a sales office in
Minnesota along with a product manufacturing and engineering facility in Waseca.
During the next few months personnel moves will be made between all locations to
improve efficiencies and focus on target markets. In closing Mr. Fuller stated,
"I am pleased with the quick progress we have made and the positive customer
response to our acquisition of EFJ."

         Transcrypt International, Inc., is a leading provider of information
security and wireless communication products. Transcrypt's information security
products prevent the unauthorized interception of sensitive voice and data
communications and its new EF Johnson subsidiary is the third largest
manufacturer of land mobile radios in the U.S. EFJ and Transcrypt have over 800
dealers and distributors in 108 countries world wide. Transcrypt International
is headquartered in Lincoln, Nebraska.
