                         NOTES TO FINANCIAL STATEMENTS
                                 MARCH 31, 1996

1.  DESCRIPTION OF THE BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Digital Transmission Systems, Inc. (the "Company") designs, manufactures,
markets and services a broad range of products for the telecommunications
industry.  The Company's primary customers are long distance carriers and
wireless service providers. The Company's products, consisting of proprietary
software and hardware modules, facilitate the control, monitoring and efficient
transmission of high-speed digital information through public or private
telecommunications networks.

     The accompanying financial statements are unaudited; however in the
opinion of management, such interim financial statements include all
adjustments, consisting only of normal recurring adjustments, necessary for a
fair presentation of the results for the interim period.  These statements
should be read in conjunction with the Company's Registration Statement on Form
SB-2.

     There have been no changes to the accounting policies of the Company
during the periods presented.  For a description of these policies, see Note 1
of the Notes to Financial Statements in the Company's Registration Statement on
Form SB-2.

2. INCOME/(LOSS) PER COMMON SHARE

     Net income/(loss) per share is computed using the weighted average number
of outstanding shares of common stock and common stock equivalents (when
dilutive). Common stock equivalents consist of the Company's common stock
issuable upon the exercise of stock options and warrants using the treasury
stock method.

     Pro forma weighted average shares outstanding gives effect to (i) the
conversion of all outstanding shares of Preferred Stock into an equal number of
shares of common stock, (ii) the conversion of $327,000 of accrued dividends
into approximately 69,000 shares of common stock, and (iii) the weighted
average of 1,070,000 shares sold in the initial public offering.

3. SUBSEQUENT EVENT

     On April 17, 1996 the Company sold 150,700 units, each of which included
one share of common stock and one warrant to purchase one share of common
stock, pursuant to an exercise of the underwriter's over-allotment option.  The
proceeds from the exercise of the over-allotment option, net of underwriting
discounts and commissions and after deducting expenses related to the exercise,
were approximately $1.0 million.


                                                                               6

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS


GENERAL

Digital Transmission Systems, Inc. (DTS) designs, manufactures, markets and
services a broad range of telecommunications products worldwide.  The Company's
primary customers are long distance carriers and wireless service providers.
The Company's products, consisting of proprietary software and hardware
modules, facilitate the control, monitoring and efficient transmission of
high-speed digital information through public or private telecommunications
networks.

DTS has been and currently is a major supplier for T1 and T3 network control
systems to MCI and T1 network control systems to Sprint. Sales to MCI have been
significant in each of the last four fiscal years, accounting for 84% for the
year ended June 30, 1995, down from 90% in the previous year. The Company's
strategy for the past two years, while maintaining its established
relationships with MCI and Sprint, has been to leverage its technology and
develop new network access products and sales channels for domestic and
international markets. As part of that strategy, the Company has focused its
direct sales force on the wireless infrastructure market in the US and has
engaged resellers for the telecommunications markets of developing countries in
Latin America, Asia and Eastern Europe. The result of this marketing strategy
is reflected in the growth in sales of the newer network access products -
FlexT1/E1 and FlexAir/SKYPLEX.

During the third quarter of fiscal 1996, DTS entered into a multi-year contract
with a major PCS (Personal Communications Services) service provider to supply
equipment for several of its largest MTA's (Major Trading Areas) in the United
States. The contract provides for cell site network access and interconnect
equipment including FlexT1/E1, as well as the Company's CNCS (Communications
Network Control System) for the provider's local and nationwide network control
and surveillance. The Company also benefited from the signing of several Latin
American and Asian reseller agreements and from a sizable order with a cellular
provider in Latin America for the FlexAir and SKYPLEX product lines.

Also during the third quarter, the Company completed an initial public offering
of its securities which was declared effective on March 4, 1996. The offering
consisted of 1,070,000 units at $7.50 per unit, each of which included one
share of common stock and one warrant to purchase one share of common stock at
$9.00 per share (120% of the offering price.)  Additionally, on April 17, 1996
the Underwriter exercised its overallotment option for the purchase of another
150,700 units. The net proceeds of the offering, approximately $7 million, will
be used primarily to fund product development and expand sales and marketing
efforts.


                                                                               7

For the three months ended March 31, 1996 and 1995, MCI accounted for 62% and
90% of net sales, respectively. Results for the three months ended March 31,
1996 reflect a shift in product mix to the Company's newer products-FlexT1/E1
and FlexAir/SKYPLEX. The Company's recently developed FlexT1/E1 product
accounted for 24% of sales for the three months ended March 31, 1996, as
compared to 6% for the three months ended March 31, 1995. The FlexAir/SKYPLEX
product sales were augmented by the addition of the SKYPLEX product line in
December 1995. The FlexAir/SKYPLEX line accounted for 9% of sales for the three
months ended March 31, 1996 reflecting sales to markets in Latin America and
Asia. There were no FlexAir/SKYPLEX product sales for the three months ended
March 31, 1995.


                                                                               8

     GROSS PROFIT. Cost of sales consists of component costs, compensation
costs and the overhead costs related to the production and shipping of the
Company's products, along with the support and warranty expense associated with
such products.  Gross profit decreased by 18%, to $1,331,000 for the three
months ended March 31, 1996 from $1,627,000 for the three months ended March
31, 1995.  As a percentage of sales, gross profit decreased to 41% for the
three months ended March 31, 1996, from 55% for the three months ended March
31, 1995.  This decrease was primarily due to the lower margin FlexT1/E1 and
FlexAir/SKYPLEX products comprising a larger percentage of total sales. In the
telecommunications industry, economies of scale are generally realized as a
product line grows. For the SKYPLEX product line, the Company purchases modules
for this product from other companies and repackages it under the DTS name. As
a result, the Company expects to continue to experience lower margins on the
SKYPLEX products than on its internally engineered and manufactured products.

     PRODUCT DEVELOPMENT.  Product development expenses consist of personnel
costs, consulting, prototyping, supplies and depreciation expenses.  Product
development expenses increased by 27%, to $642,000 for the three months ended
March 31, 1996 from $504,000 for the three months ended March 31, 1995.  This
increase resulted from increased engineering investment in new products for the
FlexT1/E1 and FlexAir product lines.  Management expects that this trend of
increasing product development expense will continue as the Company further
develops its product lines.

     SELLING, GENERAL AND ADMINISTRATIVE. Selling expenses consist primarily of
compensation costs for sales and marketing personnel, travel, consulting, trade
show and advertising expenses.  General and administrative expenses consist
primarily of compensation expenses for administrative and finance personnel, as
well as accounting, legal and consulting fees.  Selling, general and
administrative expenses increased by 10%, to $909,000 for the three months
ended March 31, 1996 from $826,000 for the three months ended March 31, 1995.
Selling expenses increased by 19%, to $725,000 for the three months ended March
31, 1996 from $609,000 for the three months ended March 31, 1995. This increase
was due primarily to the hiring of international sales staff and expansion of
the Company's international sales and marketing efforts. Management expects to
continue to expand the Company's international and domestic sales and marketing
effort and intends to increase the Company's sales and marketing expenditures.
General and administrative expenses decreased by 15%, to $184,000 for the three
months ended March 31, 1996 from $217,000 for the three months ended March 31,
1996. This decrease primarily reflects reduced salary expenses.

     NET LOSS. Net loss increased to $217,000 for the three months ended March
31, 1996 from a net profit of $256,000 for the three months ended March 31,
1995.  This increase  was caused primarily by changes in product sales mix and
planned increases in product development and sales and marketing expenses.

                                                                               9

For the nine months ended March 31, 1996 and 1995, MCI accounted for 67% and
84% of net sales, respectively.  Sales to Wiltron Company, an OEM account
selling the Company's Other Network Control equipment, accounted for 6% of
sales for the nine months ended March 31, 1996 and 2% for the nine months ended
March 31, 1995. The Company's recently developed FlexT1/E1 product accounted
for 17% of sales for the nine months ended March 31, 1996, as compared to 4%
for the nine months ended March 31, 1996.  The FlexAir/SKYPLEX product sales
were augmented by the addition of the SKYPLEX product line in December 1995.
The FlexAir/SKYPLEX line accounted for 5% of sales for the nine months ended
March 31, 1996.  There were no FlexAir/SKYPLEX product sales for the nine
months ended March 31, 1995.


                                                                              10

     GROSS PROFIT. Gross profit decreased by 13%, to $3,384,000 for the nine
months ended March 31, 1996 from $3,886,000 for the nine months ended March 31,
1995.  As a percentage of sales, gross profit decreased to 43% for the nine
months ended March 31, 1996, from 53% for the nine months ended March 31, 1995.
This decrease was primarily due to lower margin FlexT1/E1 and FlexAir/SKYPLEX
products comprising a larger percentage of total sales. In the
telecommunications industry, economies of scale are generally realized as a
product line grows. For the SKYPLEX product line, the Company purchases modules
for this product from other companies and repackages it under the DTS name. As
a result, the Company expects to continue to experience lower margins on the
SKYPLEX products than on its internally engineered and manufactured products.

     PRODUCT DEVELOPMENT.  Product development expenses increased by 29%, to
$1,791,000 for the nine months ended March 31, 1996 from $1,387,000 for the
nine months ended March 31, 1995.  This increase resulted from increased
engineering investment in new products for the FlexT1/E1 and FlexAir product
lines. Management expects that this trend of increasing Product Development
expense will continue as the Company further develops its product lines.

     SELLING, GENERAL AND ADMINISTRATIVE.  Selling, general and administrative
expenses increased by 28%, to $2,812,000 for the nine months ended March 31,
1996 from $2,201,000 for the nine months ended March 31, 1995.  Selling
expenses increased by 36%, to $2,238,000 for the nine months ended March 31,
1996 from $1,642,000 for the nine months ended March 31, 1995.  This increase
was due primarily to the addition of sales and marketing personnel as the
Company focused on penetrating new markets and obtaining new customers, and
began to expand its sales and marketing coverage of the international
marketplace.  Management expects to continue to expand the Company's sales and
marketing effort and intends to increase the Company's sales and marketing
expenditures. General and administrative expenses increased by 3%, to $574,000
for the nine months ended March 31, 1996 from $559,000 for the nine months
ended March 31, 1996. This increase primarily reflects increased compensation
expense.

     Net Loss. Net loss increased to $1,214,000 for the nine months ended March
31, 1996 from a net profit of $193,000 for the nine months ended March 31,
1995. This increase  was caused  primarily by changes in product sales mix and
planned increases in product development and sales and marketing expenses.

LIQUIDITY AND CAPITAL RESOURCES

The Company recently raised approximately $7.0 million in its initial public
offering. The proceeds will be used primarily to fund product development and
expand sales and marketing efforts. At March 31, 1996, the Company had
approximately $6.3 million in cash and short-term investments.

The Company has a bank line of credit in place with SunTrust Bank, Atlanta
which makes available $1,200,000 in borrowings secured by the Company's
accounts receivable and other assets.  At March 31, 1996, there were no
outstanding borrowings on the line of credit. A commitment fee of one quarter
of one percent is due on the unused portion of the facility. The line of credit
agreement expires on October 31, 1996.


                                                                              11

For the nine months ended March 31, 1996, the Company used $273,000 in cash
from operating activities as compared to generating $801,000 for the same
period the previous year. This change of $1,074,000 was primarily due to the
decreased earnings ($1,407,000) for the nine months ended March 31, 1996 as
compared to the nine months ended March 31, 1995. The decrease in earnings was
partially offset by $269,000 generated from the reduction of working capital
requirements.

The Company purchased $200,000 and $299,000 of property, plant and equipment
during the nine months ended March 31, 1996 and 1995, respectively. The Company
expects to significantly increase its level of capital spending in the near
term as its prepares for additional product development expenditures. The
Company also purchased $3,000,000 of short-term investments using proceeds from
the public offering during the period ended March 31, 1996. There were no such
purchases of investments during the same period of the previous year.

The Company expects its cash balances will be sufficient to fund its currently
anticipated level of losses and capital expenditures for the next twelve
months.

                                  DTS/EMPLOYEE
                              EMPLOYMENT AGREEMENT


        THIS IS AN EMPLOYMENT AGREEMENT ("this Agreement") by and between
Digital Transmission Systems, Inc., the "Company," a Delaware corporation
("DTS"), and Andres C. Salazar ("Employee"), and dated as of March 5, 1996 (the
"Effective Date"), and by which DTS and Employee, in consideration of the
mutual promises set forth below and other good and valuable consideration (the
mutuality, adequacy, sufficiency and receipt of which are hereby acknowledged),
hereby agree as follows:

        1. EMPLOYMENT.  DTS hereby employs Employee as President and CEO and
Employee agrees to perform the duties of such position as requested by the
Board of Directors, to devote his entire time and business efforts to DTS's
business, to perform his duties to the best of his ability, to promote the
success of DTS's business, and to comply with all of DTS's policies and
procedures, all pursuant to the terms of this Agreement.  Employee shall not,
during his employment pursuant to this Agreement, engage in any other business
activity or occupation for gain, profit, or other pecuniary advantage without
the prior consent of the Board of Directors of DTS; provided, however, that
such prohibition shall not prohibit Employee from investing or trading for his
own benefit in stocks, bonds, securities or other forms of investment.

        2. TERM.  The term of employment under this Agreement shall be from
March 5, 1996 through March 5, 1999 and for successive one-year periods
thereafter, with either party required to provide written notice of nonrenewal
at least one hundred eighty (180) days prior to the end of the applicable
period, unless sooner terminated as follows:

        (a) Termination by Employee:

         (I) Employee may terminate his employment pursuant to this Agreement
at any time upon ninety (90) days' prior notice to DTS, provided that the
provisions of Section 4(b) shall apply; or (ii) Employee may terminate his
employment pursuant to this Agreement for "Good Reason" (as defined below) upon
ninety (90) days' prior notice to DTS, provided that the provisions of Sections
4(a) shall apply.  For purposes of this Agreement, for Good Reason shall mean
any of the following: (i) the assignment of the Employee has changed without
his written consent to any position of materially lesser status with fewer
duties or responsibilities than the assignment held at the effective date of
this Agreement; or (ii) the assignment of the Employee has materially changed
without his written consent to any position with greater range of
responsibilities and duties than those held at the effective date of this
Agreement, unless such assignment is accompanied by a commensurate increase in
compensation agreed to in writing by the Employee.





<PAGE>   2





(b) Termination by Company:

         DTS may terminate Employee's employment pursuant to this Agreement
either (i) upon ninety (90) days' prior notice to Employee for any reason (or
for no reason), i.e. "without cause," (ii) or upon total disability of
Employee, "total disability" meaning for purposes of this Agreement, the
inability of Employee to perform assigned duties for ninety (90) consecutive
days or for thirty (30) days in any three (3)-month period, (iii) or upon death
of Employee, (iv) or upon notice at any time "for cause."  For purposes of this
Agreement: "for cause" means any reason materially and adversely affecting DTS
or any reason for which, under the circumstances, it would be unreasonable to
expect DTS to continue to employ the Employee, such as the conviction of any
felony or crime of moral turpitude, the commission or attempted commission of

                 Employee a base salary at the rate of $12,500 per month,
                 payable in accordance with DTS's payroll practices during
                 Employee's employment pursuant to this Agreement.  DTS shall

                 any increase is appropriate, (ii) Employee shall be entitled
                 to participate in any annual Management Bonus or supplementary
                 compensation program available to other senior managers in DTS
                 as approved by the Board of Directors, (iii) Employee shall be
                 entitled to participate with other employees of DTS in any
                 employee benefit plans (including retirement or pension plans)
                 as may be maintained from time to time by DTS in accordance
                 with their terms, (iv) shall be entitled to twenty (20) days
                 of vacation with pay (or such greater length of time as may be
                 approved from time to time by the Board of Directors of DTS)
                 during each fiscal year during the term of this Agreement
                 (such vacation to be taken by Employee at such time or times

                 DTS, except for any special bonuses approved





                                     -2-

                 by the Board of Directors and sales commission plans; (v)
                 Employee shall be entitled to a car allowance in the amount of
                 $500 monthly and shall not otherwise be entitled to any other
                 reimbursement for personal car use.

                 (b) Stock Options.  At the discretion of the DTS Board of
Directors, the Employee may be granted stock options in accordance with an
approved Stock Option Plan. Conditions for the vesting of those options will be
stipulated in that Plan or modified in the Stock Option Agreement.  However, if
Employee (i) is terminated by the Company for other than cause the Employee's
options will continue to vest through the notice and any severance period, or
(ii) terminates his employment for Good Reason, the Employee's options will
continue to vest as though he were terminated for other than cause. However, if
Employee (i) is terminated by the Company for other than cause, or (ii)
terminates his employment for "Good Reason," in either case, during the 365
days following a "Change in Control," all of the Employee's options will become
fully vested. If a Change in Control occurs and the Employee's employment with
the Company is terminated by the Company without cause prior to the date on
which the Change in Control occurs, and if it is reasonably demonstrated by the
Employee that such termination of employment (a) was at the request of a third
party who has taken steps reasonably calculated to effect a Change of Control
or (b) otherwise arose in connection with or anticipation of the Change of
Control, then for purposes of this section the termination will have deemed to
have taken place within the 365 day period following the Change of Control. A
Change in Control shall mean:

         (i) Approval by the shareholders of the Company of a reorganization,
         merger or consolidation, in each case, unless, following such
         reorganization, merger or consolidation more than 50% of the then
         outstanding common stock of the corporation resulting from such
         reorganization, merger or consolidation and the combined voting power
         of the then outstanding voting securities of such corporation entitled
         to vote generally in the election of directors is then beneficially
         owned, directly or indirectly, by all or substantially all of the
         individuals and entities who were the beneficial owners of the
         outstanding Company common stock immediately prior to such
         reorganization, merger or consolidation.

         (ii) The acquisition by any individual, entity or group (within the
         meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act
         of 1934, as amended ("the Exchange Act") of beneficial ownership
         (within the meaning of Rule 13d-3 promulgated under the Exchange Act)
         of 50% or more of either the then outstanding shares of common stock
         of the Company or the combined voting power of the then outstanding
         securities of the Company then entitled to vote generally in the
         election of directors; provided, however, that any acquisition by or
         from the Company shall not constitute a Change in Control.

         (iii) Approval by the shareholders of the Company of (aa) a complete
         liquidation of the Company or (bb) the sale or other disposition of
         all or substantially all of the assets of the Company, other than to a
         corporation, with respect to which following such sale or other
         disposition, more than 50% of the then outstanding shares of common
         stock of such corporation and the combined voting power of the then
         outstanding voting securities of such corporation entitled to vote
         generally in the election of directors is then beneficially owned,
         directly or indirectly, by all or substantially all of the individuals
         or entities who were the beneficial owners of the Company's
         outstanding common stock immediately prior to such sale or other
         disposition.

4. TERMINATION PAYMENTS.

         (a)     By DTS without Cause, for disability or upon death or by
Employee for Good Reason:

         terminated by DTS without cause, for disability, or upon Employee's
         death or by Employee for Good Reason, then DTS shall with appropriate
         notice period specified in 2(b):

         pro rata share of any Management Bonus Program and earned sales
         commissions through only the date of termination; Employee's accrual
         of, or participation in plans providing for, his fringe benefits shall

6. NONCOMPETITION AND NONDISCLOSURE

         (a) Background. This Agreement is being entered into by the Employee
in consideration of the Employee's employment pursuant to this Agreement. The
Employee expressly acknowledges that he has special knowledge, expertise,
contacts and other information with respect to the Restricted Business (as
defined below), and that DTS would not employ him, or make the expenditures
necessary to enable the Employee to perform the duties incident to his
employment by DTS, without obtaining the agreement of the Employee set forth in
this Section, which the Employee acknowledges and agrees are reasonable
restrictions necessary and appropriate to protect the interests of DTS.

         (b) Certain Defined Terms. For purposes of this Agreement, the
following words and phrases shall have the meaning set forth below:

                 (i) Employer. For purposes of this Section, the term
         "Employer" shall mean DTS as defined in the introductory language of
         this Agreement and its subsidiaries and affiliates.

                 (ii) Restricted Business. The phrase "Restricted Business"
         shall mean the telecommunications equipment sales and service business
         engaged in by DTS.

                 (iii) Territory. The word "Territory" shall mean any country
         in the world that DTS is "actively" marketing its products with sales
         representatives whether direct or indirect, with sales or proposals of
         sales in the last 12 months defining "activity," and with the United
         States being partitioned into states wherever DTS customers are doing
         business. The Employee acknowledges that as President and CEO, he will
         work with DTS's operations throughout such territory and that DTS must
         protect itself on such basis. The Employee recognizes and acknowledges
         that DTS, either directly or through its subsidiaries or affiliates,
         is engaged in the Restricted Business throughout the Territory and
         that it is reasonable and necessary for DTS to protect its interest on
         such basis.





                                     -5-
<PAGE>   6





         The Employee acknowledges that from time to time the Employee and DTS
may agree to change the definition of Restricted Business or Territory, but any
such changes shall be binding upon the Employee only if set forth in a written
instrument signed by the Employee.

                 (iv) Restricted Customer. For purposes of this Section, the
                 term "Restricted Customer" means (I) any actual customer to
                 whom goods or services were provided during the 12 month
                 period prior to the termination of employment pursuant to this
                 Agreement and (II) any potential customer whom DTS solicited
                 (or actively considered soliciting or had made plans to
                 solicit) during the 12 month period prior to the termination
                 of employment pursuant to this Agreement.

         (c) Non-competition. The Employee hereby agrees that he will not (i)
during the period of his employment with DTS and, (ii) if this Agreement is
terminated (aa) by the Employee other than for Good Reason, or (bb) by DTS for
cause, for a period of one year from notice of termination: (I) have any
ownership interest (whether as proprietor, partner, stockholder or otherwise)
in or, (II) be an officer, director or general or managing partner of, or hold
a similar position in, or (III) act as agent, broker or distributor for, or
advisor or consultant to, or (IV) be employed in any business (without regard
to the form in which conducted) which is engaged, or which he/she reasonably
knows is undertaking to become engaged, in the Territory in the Restricted
Business.  The ownership by the Employee of less than five percent (5%) of the
shares of capital stock of a publicly held corporation shall in no event be
deemed a violation of the foregoing.

         (d) No Interference with Restricted Customers. The Employee hereby
agrees that during the period of his employment by DTS his primary business
activity shall be as an employee of DTS, and without limiting the foregoing, he
shall solicit customers during such period only for products and services of
DTS. The Employee hereby agrees that, should this Agreement be terminated (a)
by the Employee other than for Good Reason, or (b) by DTS for cause, for a
period of one year following his notice of termination of employment with DTS
and in the Territory, he will not, in any way directly or indirectly: (I)
solicit, divert or take away or accept, or attempt to solicit, divert, take
away or accept, from DTS the business of any Restricted Customer  for any
product or service of DTS sold (or offered for sale or planned or proposed to
be offered for sale) to such Restricted Customer during the 12 month period
prior to the date of termination; or (II) attempt or seek to cause any
Restricted Customer to refrain, in any respect, from acquiring from or through
DTS any product or service of DTS sold (or offered for sale or planned or
proposed to be offered for sale) to such Restricted Customer during the 12
month period prior to the date of termination.  The Employee agrees that
telephonic or written communication by him to any of the Restricted Customers
shall constitute an activity prohibited by the foregoing.





                                     -6-
<PAGE>   7





         (e) No Interference with Employees. The Employee agrees that during
his employment pursuant to this Agreement and for a period of one year
following the end of employment hereunder, the Employee will not in any way,
directly or indirectly, request or induce any other employee of DTS to
terminate his employment with DTS.

         (f)     No Interference with Customers under contract or undergoing
contract negotiations with DTS.  The Employee agrees that for a period of one
year following the end of employment hereunder, the Employee will not in any
way, directly or indirectly, interfere with the relationship of DTS and a
customer under contract to purchase equipment and/or services from DTS, or with
contract negotiations between DTS and a prospective Customer to purchase
equipment and/or services from DTS ongoing at the time of employment
termination.

         (g) Independent. The agreements set forth in the foregoing Subsections
(a), (b), (c), (d),(e) and (f) (or any part of them) are, shall be deemed and
shall be construed as separate and independent agreements. If any such
agreement or any part of such agreement is held invalid, void or unenforceable
by any court of competent jurisdiction, such invalidity, voidness or
unenforceability shall in no way render invalid, void or unenforceable any
other part or provision thereof or any separate agreement not declared invalid,
void or unenforceable; and this Agreement shall in that case be construed as if
the void, invalid or unenforceable provisions were omitted.

7. Miscellaneous.

         (a) Notices.  Each notice under this Agreement shall be in writing and
given either in person or by telecopier, a nationally recognized next business

delegation, whether by merger or other operation of law or otherwise, of any
rights or obligations under this Agreement by a party shall be made without the
prior written consent of the other party (which shall not be unreasonably
withheld) (but given the personal nature of the services to be provided by
Employee to DTS pursuant to this Agreement, it is not expected that consent to
assignment, transfer or delegation by Employee will be granted); and no
transfer, whether by merger or other operation of law or otherwise, by DTS of
all or a substantial part of its business shall be made unless DTS's
obligations under this Agreement are assumed in connection with such transfer,
either by merger or other operation of law or by specific assumption executed
by the transferee.  This Agreement is binding upon the parties and their
respective legal representatives, heirs, devisees,

exhibits, schedules and other attachments, to it.

         (d) Severability.  Any determination by any court of competent

                                  DTS/EMPLOYEE
                              EMPLOYMENT AGREEMENT


        THIS IS AN EMPLOYMENT AGREEMENT ("this Agreement") by and between
Digital Transmission Systems, Inc., the "Company," a Delaware corporation
("DTS"), and Thomas C. Mock ("Employee"), and dated as of March 5, 1996 (the
"Effective Date"), and by which DTS and Employee, in consideration of the
mutual promises set forth below and other good and valuable consideration (the
mutuality, adequacy, sufficiency and receipt of which are hereby acknowledged),
hereby agree as follows:

        1. EMPLOYMENT.  DTS hereby employs Employee as Assistant Vice President
of Engineering and Employee agrees to perform the duties of such position as
requested by the employee's supervisor, Andres C. Salazar, DTS President and
CEO, to devote his entire time and business efforts to DTS's business, to
perform his duties to the best of his ability, to promote the success of DTS's
business, and to comply with all of DTS's policies and procedures, all pursuant
to the terms of this Agreement.  Employee shall not, during his employment
pursuant to this Agreement, engage in any other business activity or occupation
for gain, profit, or other pecuniary advantage without the prior consent of the
Board of Directors of DTS; provided, however, that such prohibition shall not
prohibit Employee from investing or trading for his own benefit in stocks,
bonds, securities or other forms of investment.

        2. TERM.  The term of employment under this Agreement shall be from
March 5, 1996 through March 5, 1998 and for successive one-year periods
thereafter, with either party required to provide written notice of nonrenewal
at least ninety (90) days prior to the end of the applicable period, unless
sooner terminated as follows:

        (a) Termination by Employee:

        (I) Employee may terminate his employment pursuant to this Agreement
at any time upon ninety (90) days' prior notice to DTS, provided that the
provisions of Section 4(b) shall apply; or (ii) Employee may terminate his
employment pursuant to this Agreement for "Good Reason" (as defined below) upon
ninety (90) days' prior notice to DTS, provided that the provisions of Sections
4(a) shall apply.  For purposes of this Agreement, for  Good Reason shall mean
any of the following: (i) the assignment of the Employee has changed without
his written consent to any position of materially lesser status with fewer
duties or responsibilities than the assignment held at the effective date of
this Agreement; or (ii) the assignment of the Employee has materially changed
without his written consent to any position with greater range of
responsibilities and duties than those held at the effective date of this
Agreement, unless such assignment is accompanied by a commensurate increase in
compensation agreed to in writing by

the Employee.

(b) Termination by Company:

         DTS may terminate Employee's employment pursuant to this Agreement
either (i) upon ninety (90) days' prior notice to Employee for any reason (or
for no reason), i.e. "without cause," (ii) or upon total disability of
Employee, "total disability" meaning for purposes of this Agreement, the
inability of Employee to perform assigned duties for ninety (90) consecutive
days or for thirty (30) days in any three (3)-month period, (iii) or upon death
of Employee, (iv) or upon notice at any time "for cause."  For purposes of this
Agreement: "for cause" means any reason materially and adversely affecting DTS
or any reason for which, under the circumstances, it would be unreasonable to
expect DTS to continue to employ the Employee, such as the conviction of any
felony or crime of moral turpitude, the commission or attempted commission of
any act of willful misconduct or dishonesty, malfeasance, gross negligence, or
the material breach of any provision of this Agreement or the general policies
as listed in the Policy Manual of DTS, as amended from time to time.  The
provisions of Section 4(a) or 4(b), as applicable, shall apply.

                          For all the services rendered to DTS by Employee in
                 any capacity pursuant to this Agreement: (i) DTS shall pay to
                 Employee a base salary at the rate of $7,500 per month,
                 payable in accordance with DTS's payroll practices during
                 Employee's employment pursuant to this Agreement.  DTS shall
                 review Employee's base salary annually to determine whether
                 any increase is appropriate, (ii) Employee shall be entitled
                 to participate in any annual Management Bonus or supplementary
                 compensation program available to other senior managers in DTS
                 as approved by the Board of Directors, (iii) Employee shall be
                 entitled to participate with other employees of DTS in any
                 employee benefit plans (including retirement or pension plans)
                 as may be maintained from time to time by DTS in accordance
                 with their terms, (iv) shall be entitled to twenty (20) days
                 of vacation with pay (or such greater length of time as may be
                 approved from time to time by the Board of Directors of DTS)
                 during each fiscal year during the term of this Agreement
                 (such vacation to be taken by Employee at such time or times
                 as shall be approved by his supervisor at DTS), and shall be
                 entitled to holidays, sick and other leave days in accordance
                 with DTS's standard policy for employees. Employee agrees that
                 the compensation and fringe benefits provided to him under
                 this Agreement



                                     -2-

        
<PAGE>   3





                 shall be the only compensation to which Employee shall be
                 entitled for his services as an employee of DTS, except for
                 any special bonuses approved by the Board of Directors and
                 sales commission plans.

                 (b) Stock Options.  At the discretion of the DTS Board of
Directors, the Employee may be granted stock options in accordance with an
approved Stock Option Plan. Conditions for the vesting of those options will be
stipulated in that Plan or modified in the Stock Option Agreement.  However, if
Employee (i) is terminated by the Company for other than cause the Employee's
options will continue to vest through the notice and any severance period, or
(ii) terminates his employment for Good Reason, the Employee's options will
continue to vest as though he were terminated for other than cause. However, if
Employee (i) is terminated by the Company for other than cause, or (ii)
terminates his employment for "Good Reason," in either case, during the 365
days following a "Change in Control," all of the Employee's options will become
fully vested. If a Change in Control occurs and the Employee's employment with
the Company is terminated by the Company without cause prior to the date on
which the Change in Control occurs, and if it is reasonably demonstrated by the
Employee that such termination of employment (a) was at the request of a third
party who has taken steps reasonably calculated to effect a Change of Control
or (b) otherwise arose in connection with or anticipation of the Change of
Control, then for purposes of this section the termination will have deemed to
have taken place within the 365 day period following the Change of Control. A
Change in Control shall mean:

         (i) Approval by the shareholders of the Company of a reorganization,
         merger or consolidation, in each case, unless, following such
         reorganization, merger or consolidation more than 50% of the then
         outstanding common stock of the corporation resulting from such
         reorganization, merger or consolidation and the combined voting power
         of the then outstanding voting securities of such corporation entitled
         to vote generally in the election of directors is then beneficially
         owned, directly or indirectly, by all or substantially all of the
         individuals and entities who were the beneficial owners of the
         outstanding Company common stock immediately prior to such
         reorganization, merger or consolidation.

         (ii) The acquisition by any individual, entity or group (within the
         meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act
         of 1934, as amended ("the Exchange Act") of beneficial ownership
         (within the meaning of Rule 13d-3 promulgated under the Exchange Act)
         of 50% or more of either the then outstanding shares of common stock
         of the Company or the combined voting power of the then outstanding
         securities of the Company then entitled to vote generally in the
         election of directors; provided, however, that any acquisition by or
         from the Company shall not constitute a Change in Control.

         (iii) Approval by the shareholders of the Company of (aa) a complete
         liquidation of the Company or (bb) the sale or other disposition of
         all or substantially all of the assets of the Company, other than to a
         corporation, with respect to which following such sale or other
         disposition, more than 50% of the then outstanding shares of common
         stock of such corporation and the combined voting power of the then
         outstanding voting securities of such corporation entitled to vote
         generally in the election of directors is then beneficially owned,
         directly or indirectly, by all or substantially all of the individuals
         or entities who were the beneficial owners of the Company's
         outstanding common stock immediately prior to such sale or other
         disposition.

         notice period specified in 2(b):

         pro rata share of any Management Bonus Program and earned sales
         commissions through only the date of termination; Employee's accrual
         of, or participation in plans providing for, his fringe benefits shall

6. NONCOMPETITION AND NONDISCLOSURE

         (a) Background. This Agreement is being entered into by the Employee
in consideration of the Employee's employment pursuant to this Agreement. The
Employee expressly acknowledges that he has special knowledge, expertise,
contacts and other information with respect to the Restricted Business (as
defined below), and that DTS would not employ him, or make the expenditures
necessary to enable the Employee to perform the duties incident to his
employment by DTS, without obtaining the agreement of the Employee set forth in
this Section, which the Employee acknowledges and agrees are reasonable
restrictions necessary and appropriate to protect the interests of DTS.

         (b) Certain Defined Terms. For purposes of this Agreement, the
following words and phrases shall have the meaning set forth below:

                 (i) Employer. For purposes of this Section, the term
         "Employer" shall mean DTS as defined in the introductory language of
         this Agreement and its subsidiaries and affiliates.

                 (ii) Restricted Business. The phrase "Restricted Business"
         shall mean the telecommunications equipment sales and service business
         engaged in by DTS.

                 (iii) Territory. The word "Territory" shall mean any country
         in the world that DTS is "actively" marketing its products with sales
         representatives whether direct or indirect, with sales or proposals of
         sales in the last 12 months defining "activity," and with the United
         States being partitioned into states wherever DTS customers are doing
         business. The Employee acknowledges that as Assistant Vice President
         of Engineering, he will work with DTS's operations throughout such
         territory and that DTS must protect itself on such basis. The Employee
         recognizes and acknowledges that DTS, either directly or through its
         subsidiaries or affiliates, is engaged in the Restricted Business
         throughout the Territory and that it is reasonable and necessary for
         DTS to protect its interest on such basis.





                                     -5-
<PAGE>   6





         The Employee acknowledges that from time to time the Employee and DTS
may agree to change the definition of Restricted Business or Territory, but any
such changes shall be binding upon the Employee only if set forth in a written
instrument signed by the Employee.

                 (iv) Restricted Customer. For purposes of this Section, the
                 term "Restricted Customer" means (I) any actual customer to
                 whom goods or services were provided during the 12 month
                 period prior to the termination of employment pursuant to this
                 Agreement and (II) any potential customer whom DTS solicited
                 (or actively considered soliciting or had made plans to
                 solicit) during the 12 month period prior to the termination
                 of employment pursuant to this Agreement.

         (c) Non-competition. The Employee hereby agrees that he will not (i)
during the period of his employment with DTS and, (ii) if this Agreement is
terminated (aa) by the Employee other than for Good Reason, or (bb) by DTS for
cause, for a period of one year from notice of termination: (I) have any
ownership interest (whether as proprietor, partner, stockholder or otherwise)
in or, (II) be an officer, director or general or managing partner of, or hold
a similar position in, or (III) act as agent, broker or distributor for, or
advisor or consultant to, or (IV) be employed in any business (without regard
to the form in which conducted) which is engaged, or which he/she reasonably
knows is undertaking to become engaged, in the Territory in the Restricted
Business.  The ownership by the Employee of less than five percent (5%) of the
shares of capital stock of a publicly held corporation shall in no event be
deemed a violation of the foregoing.

         (d) No Interference with Restricted Customers. The Employee hereby
agrees that during the period of his employment by DTS his primary business
activity shall be as an employee of DTS, and without limiting the foregoing, he
shall solicit customers during such period only for products and services of
DTS. The Employee hereby agrees that, should this Agreement be terminated (a)
by the Employee for other than Good Reason, or (b) by DTS for cause, for a
period of one year following his notice of termination of employment with DTS
and in the Territory, he will not, in any way directly or indirectly: (I)
solicit, divert or take away or accept, or attempt to solicit, divert, take
away or accept, from DTS the business of any Restricted Customer  for any
product or service of DTS sold (or offered for sale or planned or proposed to
be offered for sale) to such Restricted Customer during the 12 month period
prior to the date of termination; or (II) attempt or seek to cause any
Restricted Customer to refrain, in any respect, from acquiring from or through
DTS any product or service of DTS sold (or offered for sale or planned or
proposed to be offered for sale) to such Restricted Customer during the 12
month period prior to the date of termination.  The Employee agrees that
telephonic or written communication by him to any of the Restricted Customers
shall constitute an activity prohibited by the foregoing.





                                     -6-
<PAGE>   7





         (e) No Interference with Employees. The Employee agrees that during
his employment pursuant to this Agreement and for a period of one year
following the end of employment hereunder the Employee will not in any way,
directly or indirectly, request or induce any other employee of DTS to
terminate his employment with DTS.

         (f)     No Interference with Customers under contract or undergoing
contract negotiations with DTS.  The Employee agrees that for a period of one
year following the end of employment hereunder, the Employee will not in any
way, directly or indirectly, interfere with the relationship of DTS and a
customer under contract to purchase equipment and/or services from DTS, or with
contract negotiations between DTS and a prospective Customer to purchase
equipment and/or services from DTS ongoing at the time of employment
termination.

         (g) Independent. The agreements set forth in the foregoing Subsections
(a), (b), (c), (d), (e) and (f) (or any part of them) are, shall be deemed and
shall be construed as separate and independent agreements. If any such
agreement or any part of such agreement is held invalid, void or unenforceable
by any court of competent jurisdiction, such invalidity, voidness or
unenforceability shall in no way render invalid, void or unenforceable any
other part or provision thereof or any separate agreement not declared invalid,
void or unenforceable; and this Agreement shall in that case be construed as if
the void, invalid or unenforceable provisions were omitted.

7. Miscellaneous.

         (a) Notices.  Each notice under this Agreement shall be in writing and
given either in person or by telecopier, a nationally recognized next business
day delivery service or first class mail, postage and any other costs prepaid,
to the address of the party being given notice set forth below his or its
signature or to such other address as a party may furnish to the other as
provided in this sentence; and if notice is given pursuant to the foregoing of
a permitted successor or assign, then notice shall thereafter be given pursuant
to the foregoing to such permitted successor or assign.

delegation, whether by merger or other operation of law or otherwise, of any
rights or obligations under this Agreement by a party shall be made without the
prior written consent of the other party (which shall not be unreasonably
withheld) (but given the personal nature of the services to be provided by
Employee to DTS pursuant to this Agreement, it is not expected that consent to
assignment, transfer or delegation by Employee will be granted); and no
transfer, whether by merger or other operation of law or otherwise, by DTS of
all or a substantial part of its business shall be made unless DTS's
obligations under this Agreement are assumed in connection with such transfer,
either by merger or other operation of law or by specific assumption executed
by the transferee.  This Agreement is

exhibits, schedules and other attachments, to it.

         (d) Severability.  Any determination by any court of competent

                                  DTS/EMPLOYEE
                              EMPLOYMENT AGREEMENT


        THIS IS AN EMPLOYMENT AGREEMENT ("this Agreement") by and between
Digital Transmission Systems, Inc., the "Company," a Delaware corporation
("DTS"), and Marlin H. Nelson ("Employee"), and dated as of March 5, 1996 (the
"Effective Date"), and by which DTS and Employee, in consideration of the
mutual promises set forth below and other good and valuable consideration (the
mutuality, adequacy, sufficiency and receipt of which are hereby acknowledged),
hereby agree as follows:

        1. EMPLOYMENT.  DTS hereby employs Employee as Vice President,
International Sales and Employee agrees to perform the duties of such position
as requested by the employee's supervisor, Andres C. Salazar, DTS President and
CEO, to devote his entire time and business efforts to DTS's business, to
perform his duties to the best of his ability, to promote the success of DTS's
business, and to comply with all of DTS's policies and procedures, all pursuant
to the terms of this Agreement.  Employee shall not, during his employment
pursuant to this Agreement, engage in any other business activity or occupation
for gain, profit, or other pecuniary advantage without the prior consent of the
Board of Directors of DTS; provided, however, that such prohibition shall not
prohibit Employee from investing or trading for his own benefit in stocks,
bonds, securities or other forms of investment.

        2. TERM.  The term of employment under this Agreement shall be from
March 5, 1996 through March 5, 1998 and for successive one-year periods
thereafter, with either party required to provide written notice of nonrenewal
at least ninety (90) days prior to the end of the applicable period, unless
sooner terminated as follows:

        (a) Termination by Employee:

         (I) Employee may terminate his employment pursuant to this Agreement
at any time upon ninety (90) days' prior notice to DTS, provided that the
provisions of Section 4(b) shall apply; or (ii) Employee may terminate his
employment pursuant to this Agreement for "Good Reason" (as defined below) upon
ninety (90) days' prior notice to DTS, provided that the provisions of Sections
4(a) shall apply.  For purposes of this Agreement, for  Good Reason shall mean
any of the following: (i) the assignment of the Employee has changed without
his written consent to any position of materially lesser status with fewer
duties or responsibilities than the assignment held at the effective date of
this Agreement; or (ii) the assignment of the Employee has materially changed
without his written consent to any position with greater range of
responsibilities and duties than those held at the effective date of this
Agreement, unless such assignment is accompanied by a commensurate increase in
compensation agreed to in writing by

the Employee.

(b) Termination by Company:

         DTS may terminate Employee's employment pursuant to this Agreement
either (i) upon ninety (90) days' prior notice to Employee for any reason (or
for no reason), i.e. "without cause," (ii) or upon total disability of
Employee, "total disability" meaning for purposes of this Agreement, the
inability of Employee to perform assigned duties for ninety (90) consecutive
days or for thirty (30) days in any three (3)-month period, (iii) or upon death
of Employee, (iv) or upon notice at any time "for cause."  For purposes of this
Agreement: "for cause" means any reason materially and adversely affecting DTS
or any reason for which, under the circumstances, it would be unreasonable to
expect DTS to continue to employ the Employee, such as the conviction of any
felony or crime of moral turpitude, the commission or attempted commission of
any act of willful misconduct or dishonesty, malfeasance, gross negligence, or
the material breach of any provision of this Agreement or the general policies
as listed in the Policy Manual of DTS, as amended from time to time.  The
provisions of Section 4(a) or 4(b), as applicable, shall apply.

                 Employee a base salary at the rate of $8,500 per month,
                 payable in accordance with DTS's payroll practices during
                 Employee's employment pursuant to this Agreement.  DTS shall
                 review Employee's base salary annually to determine whether
                 any increase is appropriate, (ii) Employee shall be entitled
                 to participate in any annual Management Bonus or supplementary
                 compensation program available to other senior managers in DTS
                 as approved by the Board of Directors, (iii) Employee shall be
                 entitled to participate with other employees of DTS in any
                 employee benefit plans (including retirement or pension plans)
                 as may be maintained from time to time by DTS in accordance
                 with their terms, (iv) shall be entitled to twenty (20) days
                 of vacation with pay (or such greater length of time as may be
                 approved from time to time by the Board of Directors of DTS)
                 during each fiscal year during the term of this Agreement
                 (such vacation to be taken by Employee at such time or times
                 as shall be approved by his supervisor at DTS), and shall be
                 entitled to holidays, sick and other leave days in accordance
                 with DTS's standard policy for employees. Employee agrees that

                                     -2-
<PAGE>   3





                 shall be the only compensation to which Employee shall be
                 entitled for his services as an employee of DTS, except for
                 any special bonuses approved by the Board of Directors and
                 sales commission plans; (v) Employee shall be entitled to a
                 car allowance in the amount of $400 monthly and shall not
                 otherwise be entitled to any other reimbursement for personal
                 car use.

                 (b) Stock Options.  At the discretion of the DTS Board of
Directors, the Employee may be granted stock options in accordance with an
approved Stock Option Plan. Conditions for the vesting of those options will be
stipulated in that Plan or modified in the Stock Option Agreement.  However, if
Employee (i) is terminated by the Company for other than cause the Employee's
options will continue to vest through the notice and any severance period, or
(ii) terminates his employment for Good Reason, the Employee's options will
continue to vest as though he were terminated for other than cause. However, if
Employee (i) is terminated by the Company for other than cause, or (ii)
terminates his employment for "Good Reason," in either case, during the 365
days following a "Change in Control," all of the Employee's options will become
fully vested. If a Change in Control occurs and the Employee's employment with
the Company is terminated by the Company without cause prior to the date on
which the Change in Control occurs, and if it is reasonably demonstrated by the
Employee that such termination of employment (a) was at the request of a third
party who has taken steps reasonably calculated to effect a Change of Control
or (b) otherwise arose in connection with or anticipation of the Change of
Control, then for purposes of this section the termination will have deemed to
have taken place within the 365 day period following the Change of Control. A
Change in Control shall mean:

         (i) Approval by the shareholders of the Company of a reorganization,
         merger or consolidation, in each case, unless, following such
         reorganization, merger or consolidation more than 50% of the then
         outstanding common stock of the corporation resulting from such
         reorganization, merger or consolidation and the combined voting power
         of the then outstanding voting securities of such corporation entitled
         to vote generally in the election of directors is then beneficially
         owned, directly or indirectly, by all or substantially all of the
         individuals and entities who were the beneficial owners of the
         outstanding Company common stock immediately prior to such
         reorganization, merger or consolidation.

         (ii) The acquisition by any individual, entity or group (within the
         meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act
         of 1934, as amended ("the Exchange Act") of beneficial ownership
         (within the meaning of Rule 13d-3 promulgated under the Exchange Act)
         of 50% or more of either the then outstanding shares of common stock
         of the Company or the combined voting power of the then outstanding
         securities of the Company then entitled to vote generally in the
         election of directors; provided, however, that any acquisition by or



                                     -3-

         from the Company shall not constitute a Change in Control.

         (iii) Approval by the shareholders of the Company of (aa) a complete
         liquidation of the Company or (bb) the sale or other disposition of
         all or substantially all of the assets of the Company, other than to a
         corporation, with respect to which following such sale or other
         disposition, more than 50% of the then outstanding shares of common
         stock of such corporation and the combined voting power of the then
         outstanding voting securities of such corporation entitled to vote
         generally in the election of directors is then beneficially owned,
         directly or indirectly, by all or substantially all of the individuals
         or entities who were the beneficial owners of the Company's
         outstanding common stock immediately prior to such sale or other
         disposition.

4. TERMINATION PAYMENTS.

         commissions through only the date of termination; Employee's accrual
         of, or participation in plans providing for, his fringe benefits shall

6. NONCOMPETITION AND NONDISCLOSURE

         (a) Background. This Agreement is being entered into by the Employee
in consideration of the Employee's employment pursuant to this Agreement. The
Employee expressly acknowledges that he has special knowledge, expertise,
contacts and other information with respect to the Restricted Business (as
defined below), and that DTS would not employ him, or make the expenditures
necessary to enable the Employee to perform the duties incident to his
employment by DTS, without obtaining the agreement of the Employee set forth in
this Section, which the Employee acknowledges and agrees are reasonable
restrictions necessary and appropriate to protect the interests of DTS.

         (b) Certain Defined Terms. For purposes of this Agreement, the
following words and phrases shall have the meaning set forth below:

                 (i) Employer. For purposes of this Section, the term
         "Employer" shall mean DTS as defined in the introductory language of
         this Agreement and its subsidiaries and affiliates.

                 (ii) Restricted Business. The phrase "Restricted Business"
         shall mean the telecommunications equipment sales and service business
         engaged in by DTS.

                 (iii) Territory. The word "Territory" shall mean any country
         in the world that DTS is "actively" marketing its products with sales
         representatives whether direct or indirect, with sales or proposals of
         sales in the last 12 months defining "activity," and with the United
         States being partitioned into states wherever DTS customers are doing
         business. The Employee acknowledges that as Vice President,
         International Sales, he will work with DTS's operations throughout
         such territory and that DTS must protect itself on such basis. The
         Employee recognizes and




                                     -5-
<PAGE>   6




         acknowledges that DTS, either directly or through its subsidiaries or
         affiliates, is engaged in the Restricted Business throughout the
         Territory and that it is reasonable and necessary for DTS to protect
         its interest on such basis.

         The Employee acknowledges that from time to time the Employee and DTS
may agree to change the definition of Restricted Business or Territory, but any
such changes shall be binding upon the Employee only if set forth in a written
instrument signed by the Employee.

                 (iv) Restricted Customer. For purposes of this Section, the
                 term "Restricted Customer" means (I) any actual customer to

                 Agreement and (II) any potential customer whom DTS solicited
                 (or actively considered soliciting or had made plans to
                 solicit) during the 12 month period prior to the termination
                 of employment pursuant to this Agreement.

         (c) Non-competition. The Employee hereby agrees that he will not (i)
during the period of his employment with DTS and, (ii) if this Agreement is
terminated (aa) by the Employee other than for Good Reason, or (bb) by DTS for
cause, for a period of one year from notice of termination: (I) have any
ownership interest (whether as proprietor, partner, stockholder or otherwise)
in or, (II) be an officer, director or general or managing partner of, or hold
a similar position in, or (III) act as agent, broker or distributor for, or
advisor or consultant to, or (IV) be employed in any business (without regard
to the form in which conducted) which is engaged, or which he/she reasonably
knows is undertaking to become engaged, in the Territory in the Restricted
Business.  The ownership by the Employee of less than five percent (5%) of the
shares of capital stock of a publicly held corporation shall in no event be
deemed a violation of the foregoing.

         (d) No Interference with Restricted Customers. The Employee hereby
agrees that during the period of his employment by DTS his primary business
activity shall be as an employee of DTS, and without limiting the foregoing, he
shall solicit customers during such period only for products and services of
DTS. The Employee hereby agrees that, should this Agreement be terminated (a)
by the Employee for other than Good Reason, or (b) by DTS for cause, for a
period of one year following his notice of termination of employment with DTS
and in the Territory, he will not, in any way directly or indirectly: (I)
solicit, divert or take away or accept, or attempt to solicit, divert, take
away or accept, from DTS the business of any Restricted Customer  for any
product or service of DTS sold (or offered for sale or planned or proposed to
be offered for sale) to such Restricted Customer during the 12 month period
prior to the date of termination; or (II) attempt or seek to cause any
Restricted Customer to refrain, in any respect, from acquiring from or through
DTS any product or service of DTS sold (or offered for sale





                                     -6-
<PAGE>   7





or planned or proposed to be offered for sale) to such Restricted Customer
during the 12 month period prior to the date of termination.  The Employee
agrees that telephonic or written communication by him to any of the Restricted
Customers shall constitute an activity prohibited by the foregoing.

         (e) No Interference with Employees. The Employee agrees that during
his employment pursuant to this Agreement and for a period of one year
following the end of employment hereunder the Employee will not in any way,
directly or indirectly, request or induce any other employee of DTS to
terminate his employment with DTS.

         (f)     No Interference with Customers under contract or undergoing
contract negotiations with DTS.  The Employee agrees that for a period of one
year following the end of employment hereunder, the Employee will not in any
way, directly or indirectly, interfere with the relationship of DTS and a
customer under contract to purchase equipment and/or services from DTS, or with
contract negotiations between DTS and a prospective Customer to purchase
equipment and/or services from DTS ongoing at the time of employment
termination.

         (g) Independent. The agreements set forth in the foregoing Subsections
(a), (b), (c), (d), (e) and (f) (or any part of them) are, shall be deemed and
shall be construed as separate and independent agreements. If any such
agreement or any part of such agreement is held invalid, void or unenforceable
by any court of competent jurisdiction, such invalidity, voidness or
unenforceability shall in no way render invalid, void or unenforceable any
other part or provision thereof or any separate agreement not declared invalid,
void or unenforceable; and this Agreement shall in that case be construed as if
the void, invalid or unenforceable provisions were omitted.

rights or obligations under this Agreement by a party shall be made without the
prior written consent of the other party (which shall not be unreasonably
withheld) (but given the personal nature of the services to be provided by
Employee to DTS pursuant to this Agreement, it is not expected that consent to
assignment, transfer or delegation by Employee will be granted); and no

                                  DTS/EMPLOYEE
                              EMPLOYMENT AGREEMENT


        THIS IS AN EMPLOYMENT AGREEMENT ("this Agreement") by and between
Digital Transmission Systems, Inc., the "Company," a Delaware corporation
("DTS"), and Bobby G. Boykin ("Employee"), and dated as of March 5, 1996 (the
"Effective Date"), and by which DTS and Employee, in consideration of the
mutual promises set forth below and other good and valuable consideration (the
mutuality, adequacy, sufficiency and receipt of which are hereby acknowledged),
hereby agree as follows:

        1. EMPLOYMENT.  DTS hereby employs Employee as Vice President, U.S.
Sales and Employee agrees to perform the duties of such position as requested
by the employee's supervisor, Andres C. Salazar, DTS President and CEO, to
devote his entire time and business efforts to DTS's business, to perform his
duties to the best of his ability, to promote the success of DTS's business,
and to comply with all of DTS's policies and procedures, all pursuant to the
terms of this Agreement.  Employee shall not, during his employment pursuant to
this Agreement, engage in any other business activity or occupation for gain,
profit, or other pecuniary advantage without the prior consent of the Board of
Directors of DTS; provided, however, that such prohibition shall not prohibit
Employee from investing or trading for his own benefit in stocks, bonds,
securities or other forms of investment.

        2. TERM.  The term of employment under this Agreement shall be from
March 5, 1996 through March 5, 1998 and for successive one-year periods
thereafter, with either party required to provide written notice of nonrenewal
at least ninety (90) days prior to the end of the applicable period, unless
sooner terminated as follows:

        (a) Termination by Employee:

          (I) Employee may terminate his employment pursuant to this Agreement
at any time upon ninety (90) days' prior notice to DTS, provided that the
provisions of Section 4(b) shall apply; or (ii) Employee may terminate his
employment pursuant to this Agreement for "Good Reason" (as defined below) upon
ninety (90) days' prior notice to DTS, provided that the provisions of Sections
4(a) shall apply.  For purposes of this Agreement, for Good Reason shall mean
any of the following: (i) the assignment of the Employee has changed without
his written consent to any position of materially lesser status with fewer
duties or responsibilities than the assignment held at the effective date of
this Agreement; or (ii) the assignment of the Employee has materially changed
without his written consent to any position with greater range of
responsibilities and duties than those held at the effective date of this
Agreement, unless such assignment is accompanied by a commensurate increase in
compensation agreed to in writing by
<PAGE>   2





the Employee.

(b) Termination by Company:

         DTS may terminate Employee's employment pursuant to this Agreement
either (i) upon ninety (90) days' prior notice to Employee for any reason (or
for no reason), i.e. "without cause," (ii) or upon total disability of
Employee, "total disability" meaning for purposes of this Agreement, the
inability of Employee to perform assigned duties for ninety (90) consecutive
days or for thirty (30) days in any three (3)-month period, (iii) or upon death
of Employee, (iv) or upon notice at any time "for cause."  For purposes of this
Agreement: "for cause" means any reason materially and adversely affecting DTS
or any reason for which, under the circumstances, it would be unreasonable to
expect DTS to continue to employ the Employee, such as the conviction of any
felony or crime of moral turpitude, the commission or attempted commission of
any act of willful misconduct or dishonesty, malfeasance, gross negligence, or
the material breach of any provision of this Agreement or the general policies
as listed in the Policy Manual of DTS, as amended from time to time.  The
provisions of Section 4(a) or 4(b), as applicable, shall apply.

3. COMPENSATION.

                 Employee a base salary at the rate of $9,000 per month,
                 payable in accordance with DTS's payroll practices during
                 Employee's employment pursuant to this Agreement.  DTS shall
                 review Employee's base salary annually to determine whether
                 any increase is appropriate, (ii) Employee shall be entitled
                 to participate in any annual Management Bonus or supplementary
                 compensation program available to other senior managers in DTS
                 as approved by the Board of Directors, (iii) Employee shall be
                 entitled to participate with other employees of DTS in any
                 employee benefit plans (including retirement or pension plans)
                 as may be maintained from time to time by DTS in accordance
                 with their terms, (iv) shall be entitled to twenty (20) days
                 of vacation with pay (or such greater length of time as may be
                 approved from time to time by the Board of Directors of DTS) 
                 during each fiscal year during the term of this Agreement 
                 (such vacation to be taken by Employee at such time
                 or times as shall be approved by his supervisor at DTS), and 
                 shall be entitled to holidays, sick and other leave days in 
                 accordance with DTS's standard policy for employees. 
                 Employee agrees that the compensation and fringe benefits

                                     -2-

<PAGE>   3


         shall be the only compensation to which Employee shall be entitled for
         his services as an employee of DTS, except for any special bonuses
         approved by the Board of Directors and sales commission plans; (v)
         Employee shall be entitled to a car allowance in the amount of $400
         monthly and shall not otherwise be entitled to any other reimbursement
         for personal car use.

         (b) Stock Options.  At the discretion of the DTS Board of Directors,
the Employee may be granted stock options in accordance with an approved Stock
Option Plan. Conditions for the vesting of those options will be stipulated in
that Plan or modified in the Stock Option Agreement.  However, if Employee (i)
is terminated by the Company for other than cause the Employee's options will
continue to vest through the notice and any severance period, or (ii)
terminates his employment for Good Reason, the Employee's options will continue
to vest as though he were terminated for other than cause. However, if Employee
(i) is terminated by the Company for other than cause, or (ii) terminates his
employment for "Good Reason," in either case, during the 365 days following a
"Change in Control," all of the Employee's options will become fully vested. If
a Change in Control occurs and the Employee's employment with the Company is
terminated by the Company without cause prior to the date on which the Change
in Control occurs, and if it is reasonably demonstrated by the Employee that
such termination of employment (a) was at the request of a third party who has
taken steps reasonably calculated to effect a Change of Control or (b)
otherwise arose in connection with or anticipation of the Change of Control,
then for purposes of this section the termination will have deemed to have
taken place within the 365 day period following the Change of Control. A Change
in Control shall mean:

         (i) Approval by the shareholders of the Company of a reorganization,
         merger or consolidation, in each case, unless, following such
         reorganization, merger or consolidation more than 50% of the then
         outstanding common stock of the corporation resulting from such
         reorganization, merger or consolidation and the combined voting power
         of the then outstanding voting securities of such corporation entitled
         to vote generally in the election of directors is then beneficially
         owned, directly or indirectly, by all or substantially all of the
         individuals and entities who were the beneficial owners of the
         outstanding Company common stock immediately such reorganization,
         merger or consolidation.

         (ii) The acquisition by any individual, entity or group (within the
         meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act
         of 1934, as amended ("the Exchange Act") of beneficial ownership
         (within the meaning of Rule 13d-3 promulgated under the Exchange Act)
         of 50% or more of either the then outstanding shares of common stock
         of the Company or the combined voting power of the then outstanding
         securities of the Company then entitled to vote generally in the
         election of directors; provided, however, that any acquisition by or




  
                                     -3-
<PAGE>   4



         from the Company shall not constitute a Change in Control.

         (iii) Approval by the shareholders of the Company of (aa) a complete
         liquidation of the Company or (bb) the sale or other disposition of
         all or substantially all of the assets of the Company, other than to a
         corporation, with respect to which following such sale or other
         disposition, more than 50% of the then outstanding shares of common
         stock of such corporation and the combined voting power of the then
         outstanding voting securities of such corporation entitled to vote
         generally in the election of directors is then beneficially owned,
         directly or indirectly, by all or substantially all of the individuals
         or entities who were the beneficial owners of the Company's
         outstanding common stock immediately prior to such sale or other
         disposition.

4. TERMINATION PAYMENTS.

         commissions through only the date of termination; Employee's accrual
         of, or participation in plans providing for, his fringe benefits shall

soon as is practicable.

6. NONCOMPETITION AND NONDISCLOSURE

         (a) Background. This Agreement is being entered into by the Employee
in consideration of the Employee's employment pursuant to this Agreement. The
Employee expressly acknowledges that he has special knowledge, expertise,
contacts and other information with respect to the Restricted Business (as
defined below), and that DTS would not employ him, or make the expenditures
necessary to enable the Employee to perform the duties incident to his
employment by DTS, without obtaining the agreement of the Employee set forth in
this Section, which the Employee acknowledges and agrees are reasonable
restrictions necessary and appropriate to protect the interests of DTS.

         (b) Certain Defined Terms. For purposes of this Agreement, the
following words and phrases shall have the meaning set forth below:

                 (i) Employer. For purposes of this Section, the term
         "Employer" shall mean DTS as defined in the introductory language of
         this Agreement and its subsidiaries and affiliates.

                 (ii) Restricted Business. The phrase "Restricted Business"
         shall mean the telecommunications equipment sales and service business
         engaged in by DTS.

                 (iii) Territory. The word "Territory" shall mean any country
         in the world that DTS is "actively" marketing its products with sales
         representatives whether direct or indirect, with sales or proposals of
         sales in the last 12 months defining "activity," and with the United
         States being partitioned into states wherever DTS customers are doing
         business. The Employee acknowledges that as Vice President, U.S.
         Sales, he will work with DTS's operations throughout such territory
         and that DTS must protect itself on such basis. The Employee
         recognizes and acknowledges that DTS, either directly or through its
         subsidiaries or affiliates, is engaged in the Restricted Business
         throughout the Territory and that it is




                                     -5-
<PAGE>   6





         reasonable and necessary for DTS to protect its interest on such
         basis.

         The Employee acknowledges that from time to time the Employee and DTS
may agree to change the definition of Restricted Business or Territory, but any
such changes shall be binding upon the Employee only if set forth in a written
instrument signed by the Employee.

                 (iv) Restricted Customer. For purposes of this Section, the
                 term "Restricted Customer" means (I) any actual customer to
                 whom goods or services were provided during the 12 month
                 period prior to the termination of employment pursuant to this
                 Agreement and (II) any potential customer whom DTS solicited
                 (or actively considered soliciting or had made plans to
                 solicit) during the 12 month period prior to the termination
                 of employment pursuant to this Agreement.

         (c) Non-competition. The Employee hereby agrees that he will not (i)
during the period of his employment with DTS and, (ii) if this Agreement is
terminated (aa) by the Employee other than for Good Reason, or (bb) by DTS for
cause, for a period of one year from notice of termination: (I) have any
ownership interest (whether as proprietor, partner, stockholder or otherwise)
in or, (II) be an officer, director or general or managing partner of, or hold
a similar position in, or (III) act as agent, broker or distributor for, or
advisor or consultant to, or (IV) be employed in any business (without regard
to the form in which conducted) which is engaged, or which he/she reasonably
knows is undertaking to become engaged, in the Territory in the Restricted
Business.  The ownership by the Employee of less than five percent (5%) of the
shares of capital stock of a publicly held corporation shall in no event be
deemed a violation of the foregoing.

         (d) No Interference with Restricted Customers. The Employee hereby
agrees that during the period of his employment by DTS his primary business
activity shall be as an employee of DTS, and without limiting the foregoing, he
shall solicit customers during such period only for products and services of
DTS. The Employee hereby agrees that, should this Agreement be terminated (a)
by the Employee for other than Good Reason, or (b) by DTS for cause, for a
period of one year following his notice of termination of employment with DTS
and in the Territory, he will not, in any way directly or indirectly: (I)
solicit, divert or take away or accept, or attempt to solicit, divert, take
away or accept, from DTS the business of any Restricted Customer  for any
product or service of DTS sold (or offered for sale or planned or proposed to
be offered for sale) to such Restricted Customer during the 12 month period
prior to the date of termination; or (II) attempt or seek to cause any
Restricted Customer to refrain, in any respect, from acquiring from or through
DTS any product or service of DTS sold (or offered for sale or planned or
proposed to be offered for sale) to such Restricted Customer during the 12
month period prior to the date of termination.  The Employee agrees that
telephonic




                                     -6-
<PAGE>   7





or written communication by him to any of the Restricted Customers shall
constitute an activity prohibited by the foregoing.

         (e) No Interference with Employees. The Employee agrees that during
his employment pursuant to this Agreement and for a period of one year
following the end of employment hereunder the Employee will not in any way,
directly or indirectly, request or induce any other employee of DTS to
terminate his employment with DTS.

         (f)     No Interference with Customers under contract or undergoing
contract negotiations with DTS.  The Employee agrees that for a period of one
year following the end of employment hereunder, the Employee will not in any
way, directly or indirectly, interfere with the relationship of DTS and a
customer under contract to purchase equipment and/or services from DTS, or with
contract negotiations between DTS and a prospective Customer to purchase
equipment and/or services from DTS ongoing at the time of employment
termination.

         (g) Independent. The agreements set forth in the foregoing Subsections
(a), (b), (c), (d), (e) and (f) (or any part of them) are, shall be deemed and
shall be construed as separate and independent agreements. If any such
agreement or any part of such agreement is held invalid, void or unenforceable
by any court of competent jurisdiction, such invalidity, voidness or
unenforceability shall in no way render invalid, void or unenforceable any
other part or provision thereof or any separate agreement not declared invalid,
void or unenforceable; and this Agreement shall in that case be construed as if
the void, invalid or unenforceable provisions were omitted.

assignment, transfer or delegation by Employee will be granted); and no
transfer, whether by merger or other operation of law or otherwise, by DTS of
all or a substantial part of its business shall be made unless DTS's
