         2.1      LMC hereby grants Triton for the term of this Agreement an
exclusive, nontransferable (except as otherwise provided in Section 2.5 hereof)
license under LMC Intellectual Property Rights to make, have made, improve, have
improved, use, sell, and offer to sell throughout the Territory, Commercial
Systems incorporating Millimeter Wave


                                       4

<PAGE>   5


MMIC Design Technology and related LMC Intellectual Property, provided, however
that LMC expressly reserves whatever rights in the Millimeter Wave MMIC Design
Technology and related LMC Intellectual Property as may be necessary or useful
to enable LMC to continue in existing pursuits and to pursue future business in
natural areas of expansion. The reservation expressed herein shall not be deemed
or interpreted to limit Triton's right to make, have made, improve, have
improved, use, sell and offer to sell Commercial Systems as aforesaid. Moreover,
LME&M shall extend to Triton a right of first refusal to supply to LME&M MEDs
then being manufactured by or for Triton, or variations on an MED which could be
produced by Triton within a competitive timeframe, and supplied by Triton to
others. This extension to Triton of a right of first refusal is limited to those
instances where LME&M's activities pursuant to the reservation expressed herein
would otherwise be inconsistent with the aforesaid exclusive grant of rights to
Triton.

         2.2      The scope of the license granted in Section 2-1 above is
limited to the design, manufacture, use, sale, offer for sale, and importation
of Commercial Systems. No other right or license under the Millimeter Wave MMIC
Design Technology and related LMC Intellectual Property is herein granted.

         2.3      From the Effective Date hereof, Triton agrees to pay LMC a
royalty on each MED utilizing Millimeter Wave MMIC Design Technology that Triton
sells or otherwise disposes of, all in accordance with the following rules:

                  (a)      The amount payable as a royalty to LMC shall be
determined in accordance with this Section 23 and the royalty schedule set forth
in Exhibit C hereto.

                  (b)      For the purposes of this Section, an MED utilizing
Millimeter Wave


                                       5

<PAGE>   6


MMIC Design Technology that has not been sold shall be deemed "otherwise
disposed of" whenever in return for valuable consideration such system is
delivered by Triton to a third party or put into use by Triton either on behalf
of a third party or for any purpose other than demonstration and/or routine
testing. The sales price deemed to apply to any system "otherwise disposed of"
for the purposes of computing the royalty shall be the sales price at which
Triton or any of its subsidiaries or affiliates at the time is offering products
of similar kind and quality, less any customary discount that Triton is offering
on such system.

                  (c)      For Purposes of this Section and Exhibit C, the gross
sales price for the purposes of computing LMC's royalty shall be only the fair
gross sales price of the MED included in the system, it being specifically
acknowledged that Triton shall on its own develop or purchase from others
certain software for the MED and certain hardware and software for related items
that ultimately will constitute a majority of the selling price of each system.
LMC shall not be entitled to a royalty on any portions of any system sold by
Triton other than in respect of the gross sales price of the portion of the MED
which LMC developed.

                  (d)      The parties should mutually agree on the value. If
the parties are unable to agree on what portion of the selling price of an
integrated system is fairly allocable to the hardware of the MED (and therefore
constitutes the gross sales price of the MED) and what portion of such selling
price is fairly allocable to the balance of the system (including both software
for the MED and hardware and software for the related items), they shall submit
that question to binding arbitration in Orlando, Florida through the American
Arbitration Association.

                  (e)      If Triton pays LMC all sums required for five years
after the date


                                       6

<PAGE>   7

Triton first sells or otherwise disposes of an MED, then the license granted in
Section 2.1 above shall be deemed to be fully paid up.

         2.4      Triton agrees to furnish to LMC, within thirty days of the end
of each calendar quarter, a written royalty report setting forth the number of
MED's sold or otherwise disposed of, or, where the Millimeter Wave MMIC Design
Technology is incorporated into a higher assembly, the number of such higher
assemblies sold or otherwise disposed of, the sales price of such products, the
royalties due thereon, and the manner in which Triton calculated said royalties.
With each quarterly royalty report, Triton shall also submit financial
statements of Triton that break out in detail LMC designed Millimeter Wave MMIC
Design Technology sales and royalty payment checks, with such financial
statements to be certified as to accuracy and completeness by Triton's chief
financial officer. LMC shall have the right to cause an audit of Triton's books
and records to be performed at LMC's expense by an independent auditor
reasonably acceptable to Triton. The sole objective of that audit shall be to
verify reported LMC designed Millimeter Wave MMIC Design Technology sales.
Triton shall cooperate with the audit by affording the auditor access to the
names and addresses of Triton customers for systems involving Millimeter Wave
MMIC Design Technology.

         2.5      The license granted to Triton in this Section shall be
assignable to new commercial ventures that are owned in whole or in part by
Triton providing that Triton notifies LMC of such assignment and that the new
commercial venture accepts in writing all terms of this Agreement. Nothing in
this Agreement shall be construed to preclude the license from going with Triton
in connection with any change in control of Triton or any sale of substantially
all of the assets or business of Triton to a third party.

in the Millimeter Wave MMIC Design Technology development area. LMC will,
however, have the right to use standard advertising methods and job postings
when searching for individuals to support its Millimeter Wave MMC Design
Technology development activities. It shall not be a violation of this Section
for LMC to hire any Triton employee who approaches LMC, either as a consequence
of such standard advertising methods and job postings or otherwise as long as
LMC shall not have initiated the contact for the purpose of recruitment.

<PAGE>   9


         4.1      Except with the consent of LMC, in no event may Triton, its
affiliates or subsidiaries hire any current or former employee of LME&M who
performs or performed significant duties for LME&M relating to the design and
development of millimeter wave products, methods and components. As used in this
Section:

                  (a)      the term "former employee" shall refer to a person
         who has been employed by LME&M at any time within the four month period
         immediately preceding the start of such person's employment with
         Triton; and

                  (b)      the term "significant duties" shall mean that such
         current or former employee charged half or more of his or her time to
         activities relating to the design and development of millimeter wave
         products, methods and components.

         4.2      Triton will submit to Lockheed Martin Electronics and Missiles
(Ocala) commercial manufacturing facility requests for quotes on the
manufacturing of MED products. Triton will be under no obligation to make awards
if Triton in good faith determines that Ocala is non-competitive.

         4.3      For so long as the Agreement is in effect, LMC shall have the
right of first negotiation with respect to any product development work that
Triton intends to have performed by a third party with respect to millimeter
wavelength communications products. Whenever Triton has determined that it will
seek a third party to perform such work, Triton will issue a
request-for-proposal (RFP) to LMC with the RFP containing that level of detail
that Triton intends to present to third parties for such work. This RFP shall be
issued to LMC prior to any discussion or negotiations with third parties with
respect to


                                       9

<PAGE>   10

performing such work. LMC shall have 30 days within which to submit a proposal
to Triton per the RFP. LMC may elect not to make a proposal with respect to such
work, in which case it will notify Triton of this decision as soon as such
decision is reached.

         4.4 Upon receipt of the LMC proposal by Triton within the 30-day
period, LMC and Triton agree to negotiate in good faith, on an exclusive basis,
towards a contract for such work. In the event that Triton and LMC cannot reach
agreement on the contract within 30 days after the delivery of the LMC proposal
to Triton, Triton shall have the right to discuss and negotiate with third
parties and enter into such contract with a third party provided that Triton
first certifies in writing to LMC that the terms of such contract are materially
better than the terms last offered by LMC in respect to such contract.

         4.5 Triton, upon consummation and as a requirement of this Agreement,
and in accordance with its covenants, agrees to provide the Central Florida
Innovation Corporation with 1% equity in Triton.

         4.6 LMC has the right at its sole discretion to participate in any
future sales of equities by Triton after its initial financing, at the agreed
valuation not exceeding 10% total ownership. Triton shall provide LMC with prior
written notification of any such sales of equities, such written notification to
be timely and in no event less than sixty (60) days prior to such sales of
equities.

         4.7 At any time during the period beginning 28 months from the
Effective Date of this Agreement and ending 34 months from the Effective Date of
this Agreement LMC may, at its sole option, convert the right to receive
royalties set forth in this Agreement (the "Royalty Right") into a stock option
(the "Stock Option"), the terms of which are set forth below. Such conversion
shall take place on the date LMC




                                       10
<PAGE>   11

notifies Triton in writing (the "Conversion Date") that it has exercised its
right to convert the Royalty Right into the Stock Option. All royalties due to
LMC arising out of royalty bearing sales or other dispositions which have
occurred prior to the Conversion Date shall be paid to LMC according to the
terms for such payment contained in this Agreement. The payment by Triton to LMC
of the lump sum payment specified in Exhibit C at any time prior to LMC
notifying Triton of LMC's election to convert the Royalty Right into the Stock
Option shall be deemed to terminate LMC's right to convert.

Upon conversion, LMC shall have a 5-year option to acquire, at no cost capital
stock in Triton having a fair market value Of $4,000,000 as of the Conversion
Date. If Preferred Stock has been issued by Triton, LMC will receive Preferred
Shares, convertible one-for-one into Common Shares, with rights equivalent to
the rights associated with existing Preferred Stock. If no shares of Preferred
Stock have been issued before the Conversion Date, or if all preferred shares
have been issued but have been converted to Common Stock, the option stock shall
be shares of Common Stock having the same rights as shares of Common Stock last
sold to investors prior to the conversion date. The fair market value of capital
stock shall be determined in good faith by the Triton Board of Directors,
subject to determination by appraisal in the event that LMC disagrees with this
valuation. In the event that determination by appraisal is necessary, LMC and
Triton shall mutually agree upon a qualified appraiser. The appraiser shall
determine the fair market value of the capital stock using traditional methods
of appraisal and will attribute relative value to the various classes of capital
stock. Such determination by the appraiser shall be final. The Stock Option and
the shares underlying the Stock Option shall be fully assignable by the holder
thereof and its assignees, subject only to compliance by the holder with
applicable securities laws.

               EXHIBIT A - MILLIMETER WAVE MMIC DESIGN TECHNOLOGY


         The following items constitute current or anticipated technology which
will be utilized in the design of the MED:

1) MMW TRANSCEIVER FOR DIGITAL COMMUNICATIONS.

The object of this proprietary design is to obtain a MMW transceiver which
provides at least 1 Watt CW of power over a frequency range of 38.6 to 40.0 GHz
while operating as a continuous-duty, full-duplex transceiver. The design
incorporates [*] LO/2 (1/2 Local Oscillator) [*] for [*] transmit and
receive functions. This is accomplished by matching the [*]. The exciter
section, of this design, uses [*], 50 MHz ultra-low-phase-noise oscillator [*]
for [*]-duplex channels. The [*] LO/2 frequencies are generated from a [*]
within this design. A [*] precise sampling frequency [*] is locked with the 50
MHz reference. The result of this design allows the two ends of the link to be
[*]-locked thus obtaining Zero Frequency Error between MMW link and Datum
carriers. A disclosure filing is planned for this design.

2) MMW MMIC CIRCUITS.

LME&M are currently evaluating MMIC circuits for both the prototype and
production designs. It is probable that the prototype will primarily use
non-proprietary circuitry. For improved performance, however, the final design
may use proprietary circuitry using trade secrets developed by LME&M.
Disclosures will be filed at the discretion of the parties.

3) RADOME TECHNOLOGY.
There are 3 LMC patents that cover the following technologies that will be
evaluated for use in the MED antenna/radome system:

The first patent covers an absorptive/transmissive structure which can be used
to fabricate [*] without disrupting the electromagnetic waves generated by the
antenna. [*] This technology maybe useful in minimizing EMI emissions from the
MED (which will help meet FCC regulations) and to minimize outside EMI
emissions from getting into the MED.

The second patent relates to a method for fabricating a substantially nonplanar
substrate having a predetermined pattern. More particularly, the present
invention relates to a method for fabricating a [*] surface on to a radome by
ablating the [*] into a resist layer and removing [*] metallized layer or by
ablating the [*] into a metallized layer. This patent also maybe used to
fabricate radomes with band pass characteristics.

The third patent is an anti-ice radome having a [*] plurality of resistive
heating elements. The [*] surface prevents the resistive heating elements from
disturbing the electromagnetic waves generated by the antenna within the radome.
Thus, ice formation on the radome can be prevented without sacrificing the
transmission characteristics of the radome.

These technologies will be evaluated in conjunction with the design of the MED
antenna/radome assemblies.
