         5.5      Technology Escrow. ThinKom agrees during the term of this
                  Agreement to create and maintain current copies of any
                  technical drawings or other technical documents relating to
                  the design and specifications of the Antenna Module developed
                  under this Agreement (such copies the "IP Materials"). Within
                  90 days after the Effective Date, ThinKom will enter into
                  binding contractual arrangement with a commercial escrow agent
                  mutually agreeable to the Parties (the "Escrow Agent")
                  according to which the Escrow Agent will agree (i) to hold and
                  safeguard the escrowed IP Materials during the term of this
                  Agreement, and (ii) to release a copy of such escrowed IP
                  Materials to Gigabeam if and when ThinKom enters into
                  bankruptcy, liquidates or winds up its business during the
                  term of this Agreement. Gigabeam acknowledges that the Escrow
                  Agent will not be authorized to deliver or otherwise provide
                  access to the escrowed IP Materials other than as described
                  above.

                  Subject to the delivery to Gigabeam of the escrowed IP
                  Materials in accordance with this Section 5.5, ThinKom hereby
                  grants to Gigabeam a non-exclusive, worldwide, royalty-bearing
                  right and license under any Intellectual Property Rights of
                  ThinKom to use such escrowed IP Materials for any purpose in
                  the Field of Exclusivity if provided to Gigabeam as
                  contemplated in this Section 5.5. Such license will continue,
                  notwithstanding any termination of this Agreement, until the
                  date upon which the then-current four year initial term or one
                  year renewal terms under Section 4, as the case may be, would
                  have expired.

                  In consideration for the foregoing license grant, for so long
                  as Gigabeam makes use of ThinKom's Antenna Module product
                  designs or any other form of ThinKom IP, Gigabeam agrees to
                  pay to ThinKom, any License Fees normally payable under this
                  Agreement as if ThinKom had not wound up or liquidated its
                  business but with such Fees payable to be net of any
                  incremental costs incurred by Gigabeam required to provide for
                  a continued supply of Antenna Modules to Gigabeam. GigaBeam
                  shall pay such License Fees, net of any incremental costs, on
                  a quarterly basis in arrears, which payments shall each be due
                  within thirty (30) days following the end of the preceding
                  calendar quarter.

6.       Confidentiality.

         6.1      Obligation. Each party agrees to treat all non-public written
                  and oral information communicated to it by the other party in
                  connection with the activities contemplated by this Agreement
                  ("Confidential Information"), including the existence or
                  nature of their discussions, as confidential, and neither
                  party will use or disclose such Confidential Information for
                  purposes other than the activities contemplated by this
                  Agreement; provided however that Gigabeam and ThinKom may
                  disclose such Confidential Information for the purposes of
                  obtaining financing.

                                  Page 5 of 17
<PAGE>

         6.2      Exceptions. Confidential Information will not include
                  information that (i) the receiving party independently
                  developed (as shown by documentary evidence) or obtained from
                  a source not under an obligation of confidentiality to the
                  disclosing party, (ii) is or becomes publicly available
                  through no act or omission of the receiving party, (iii) the
                  receiving party receives the prior written consent of the
                  disclosing party to disclose, or (iv) the receiving party is
                  required by law to disclose; provided the receiving party
                  promptly notifies the disclosing party and cooperates with the
                  disclosing party to protect the confidentiality of the
                  Confidential Information before any tribunal or governmental
                  agency; provided that only the specific Confidential
                  Information that meets the exclusion shall be excluded and not
                  any other Confidential Information that happens to appear in
                  proximity to such excluded portion (for example, a portion of
                  a document may be excluded without affecting the confidential
                  nature of those portions that do not themselves qualify for
                  exclusion). The burden of proving these exceptions shall rest
                  with the receiving party.

         6.3      Termination of Agreement. Upon termination of this Agreement,
                  at the request of the disclosing party, the receiving party
                  will return all copies of the other party's Confidential
                  Information, or certify to the other party in writing that all
                  copies of the other party's Confidential Information have been
                  destroyed. The parties agree that any breach or threatened
                  breach of this Section 6 by a receiving party would cause not
                  only financial harm, but irreparable harm to the disclosing
                  party and that money damages will not provide an adequate
                  remedy. In the event of a breach or threatened breach of this
                  Section 6 by a receiving party, the disclosing party shall, in
                  addition to any other rights and remedies it may have, be
                  entitled to an injunction (without the necessity of posting
                  any bond or surety) restraining the receiving party from
                  disclosing or using, in whole or in part, any Confidential
                  Information.

7.       Limitation of Liability.

         IN NO EVENT SHALL EITHER PARTY BE LIABLE TO THE OTHER FOR ANY LOSS OF
         PROFITS OR OTHER INCIDENTAL, INDIRECT, SPECIAL, EXEMPLARY, OR
         CONSEQUENTIAL DAMAGES, EVEN IF SUCH PARTY HAS BEEN ADVISED OF THE
         POSSIBILITY OF SUCH DAMAGES. IN NO EVENT SHALL EITHER PARTY BE LIABLE
         TO THE OTHER FOR CLAIMS OR DEMANDS BROUGHT AGAINST THE OTHER PARTY BY A
         THIRD PARTY UNDER THIS AGREEMENT, EVEN IF SUCH PARTY HAS BEEN ADVISED
         OF THE POSSIBILITY OF SUCH DAMAGES.

         ThinKom will not compete by offering similar Product to be offered by
         GigaBeam and GigaBeam will not compete by offering antenna products
         developed and available for sale by ThinKom and neither party will not,

         negotiate or pursue any other transaction or arrangement that
         contemplates a relationship with any third party that will be in
         conflict with the Licensed Field.

9.       Cost Reduction and Pricing of Antenna Modules Sold to Gigabeam

         ThinKom shall use its best and reasonable efforts to continue to reduce
         the cost of Antenna Modules sold to Gigabeam. Where and when
         appropriate, ThinKom shall jointly work with Gigabeam towards such cost
         reductions including but not limited to expenditure on tooling and by
         other means. Pricing of Antenna Modules sold to Gigabeam shall be at
         ThinKom's direct labor cost plus direct material cost, manufacturing
         overhead, warranty and at ThinKom's fully burdened non-recurring
         engineering cost (which includes cost for tooling) all of which shall
         be paid for by Gigabeam through its Purchase Lot orders pursuant to
         Sections 1.1.5, Section 11 and 3.1 and by separate payments pursuant to
         Section 3.2.

10.      License Fee and Antenna Manufacturing Fee

         Gigabeam shall pay to ThinKom a License Fee as specified in Section
         1.1.6 subject to an Acquisition Event upon the occurrence of which the
         License Fee will cease for all calendar quarters subsequent to the
         Acquisition Event and in lieu thereof an Antenna Manufacturing Fee will
         be paid to ThinKom pursuant to Section 1.1.7 commencing immediately
         after the occurrence of the Acquisition Event. For the purpose of this
         Agreement, Acquisition Event shall be a change in ownership of at least
         seventy five percent (75%) of the Outstanding voting Stock of Gigabeam.
         The License Fee is to be an amount equivalent to one percent (1%)
         of Gigabeam's Revenue net of shipping costs, taxes, installation costs
         and other costs, including reimbursable costs, directly associated with
         generation of revenue. Revenue shall include sales of Gigabeam's
         Products incorporating ThinKom's antennas and any service revenue
         generated from maintenance and service of such Products. Payment of a
         License Fee to ThinKom will commence upon generation of Revenue to
         Gigabeam from sales of Gigabeam's Product incorporating ThinKom's
         Antenna Modules. The Antenna Manufacturing Fee is to be an amount of
         two and one half times the direct labor plus the direct material cost,
         manufacturing overhead, and warranty (2.5 X (DIRECT LABOR + DIRECT
         MATERIAL + MANUFACTURING OVERHEAD + WARRANTY) to manufacture each
         Antenna Module. The License Fee will be payable quarterly with the
         License Fee due thirty days after the close of each calendar quarter.
         The Antenna Manufacturing Fee is payable monthly within thirty days
         following the end of each month in which Antenna Modules are shipped to
         Gigabeam or Gigabeam's designated location or facility following the
         occurrence or closing by the parties involved in the Acquisition Event.

11.      Purchase Lot Orders

         Gigabeam shall place Purchase Lot Orders with ThinKom for Antenna
         Modules for Gigabeam's Product pursuant to Section 1.1.5. Gigabeam
         commits during the Term of this Agreement to place Minimum Purchase Lot
         Orders pursuant to Section 1.1.5 and as specified in Exhibit D. Each
         Purchase Lot Order shall cover ThinKom's cost of non-recurring
         engineering, tooling and cost of goods (direct labor, direct material,
         manufacturing overhead, and warranty) for the production of the Antenna
         Modules. Gigabeam shall place Purchase Lot Orders for new Antenna
         Modules at least six months in advance but preferably eight months in
         advance of expected delivery to Gigabeam or Gigabeam's designated
         facility. After commencement of production of any Antenna Module
         design, Gigabeam shall place subsequent Purchase Lot Orders at least
         three months in advance. Upon placement of Purchase Lot Orders,
         Gigabeam shall pay to ThinKom a down payment of 30% of each Purchase
         Lot Order. Remaining payments (less 30%) are due thirty (30) days after
         receipt by Gigabeam of each regular shipment from ThinKom of portions
         of the total lot order quantity.

         Gigabeam will cooperate with ThinKom to insure that ThinKom will be
         cash flow positive after taking into account its costs and expenditures
         relating to the performance of this Agreement and as compared to
         License Fees, Manufacturing Fees, down payments and remaining payments
         on Purchase Lot Orders received by ThinKom from Gigabeam. In the event
         that ThinKom's cash flow is not positive, Gigabeam will agree to
         restructure the amounts of and timing of its payments relating to
         Purchase Lot Orders.

12.      Equity Incentives

         The parties have established performance incentives whereby each party
         will issue to the other common stock.

         Gigabeam shall issue to ThinKom Common Stock in Gigabeam in an amount
         representing five percent (5%) of the Stock Outstanding on a fully
         diluted basis (including this proposed Stock Grant) of Gigabeam within
         fourteen days of the execution of this Agreement. The Price per Share
         of the Stock shall be the same price as for the founders of Gigabeam.

         ThinKom shall issue to Gigabeam Common Stock in ThinKom prior to the
         end of each calendar year with the amount of Stock to be issued to be
         calculated by dividing the amount of License Fee paid to ThinKom in the
         same year by the price per share of the ThinKom Common Stock. The Price
         per Share of ThinKom Common Stock shall be based upon outside
         investments in ThinKom or by mutual agreement between ThinKom and
         Gigabeam management. If ThinKom and Gigabeam management cannot mutually
         agree on a price per share, then both parties shall mutually agree on a
         third party agent to set the market price per share of the Stock.
         Gigabeam shall pay any costs associated with the valuation of ThinKom's
         Common Stock. The Price per Share of Thinkom Common Stock for the
         purpose of this award shall be set no more than once per year and as
         close as practical to the date of award of the Stock. Under this
         program, Gigabeam shall acquire no more than five percent (5%) of
         ThinKom's Common Stock with the calculation to be based upon the amount
         of Stock outstanding on a fully diluted basis (including this proposed
         Stock amount) as at execution of this Agreement.

                                  Page 8 of 17

         applicable corporate documents, including, but not limited to, the
         appropriate shareholder agreements.

13.      Advance of Working Capital

         Gigabeam shall pay to ThinKom an amount of $250,000 (two hundred and
         fifty thousand dollars) which is to be an Advance of Working Capital
         with payment to be made within 30 days (thirty days) of close of
         GigaBeam's funding by outside investors of at least $4 million (four
         million dollars). This Advance of Working Capital will credited against
         amounts payable by Gigabeam to ThinKom within or following the last
         calendar quarter of year 2006.

14.      Audit

         Each party shall have the right to audit the books and accounts of the
         other party for the sole purposes so that ThinKom can establish that
         the License Fees pursuant to Section 10 as paid by Gigabeam are the
         correct amounts and Gigabeam can establish that the costs pursuant to
         Section 9 are the correct amounts.

                             CONVERTIBLE DEMAND NOTE

                                  June 10, 2004

         For value received, GIGABEAM CORPORATION, a Delaware corporation (the
"Company"), hereby unconditionally promises to pay to the order of AMERISTOCK
CORP. or its registered assigns (the "Payee"), ON DEMAND, the principal sum of
Two Hundred Thousand Dollars ($200,000.00), together with interest thereon, and
premium, if any, all as hereinafter provided, if not earlier converted pursuant
to the Agreement (as hereinafter defined). Such principal sum, together with all
interest incurred thereon, premium (if any), and all other fees and costs, shall
be due and payable ON DEMAND and, except as provided herein, the Payee's right
to make demand is unconditional and unlimited; notwithstanding the foregoing,
prior to the one year anniversary of the date of issuance of this Note (the
"Maturity Date"), the Payee may only make demand (if not earlier converted as
provided in the Agreement): (i) following the occurrence and continuance of an
Event of Default (as such term is defined in the Agreement) or (ii) immediately
prior to the closing of a Change of Control (as such term is defined in the
Agreement), which shall permit the acceleration and demand of this Note.

         The Company agrees that the Payee, in the exercise of the Payee's sole
discretion, may make demand at any time after the Maturity Date whether or not
any Event of Default or Change of Control has occurred and is continuing, and
may make demand at any time either before or after the Maturity Date in the
event of either of the occurrences described in items (i) and (ii) of the
immediately preceding paragraph of this Note. The Company agrees that, in
exercising its discretion, the Payee may make demand for any reasons which it
deems appropriate, and such reasons may be related or unrelated to the Company,
its business or financial condition or prospects. The Payee's right to make
demand is a continuing right, and acceptance by the Payee of any payment after
demand shall not be deemed a waiver of such right to make demand on any other
occasion.

         Prior to the date upon which the balance of this Note becomes due and
payable as described herein, whether by demand or otherwise (the "Payment Due
Date") and after the Payment Due Date, the unpaid principal balance outstanding
on all advances, from time to time, hereunder shall accrue interest at a rate
equal to ten percent (10%) per annum. Interest shall be compounded annually and
shall be computed on the basis of a 360-day year and a 30-day month.
Notwithstanding any other provision of this Note, the Payee does not intend to
charge and the Company shall not be required to pay any interest or other fees
or charges in excess of the maximum permitted by applicable law; any payments in
excess of such maximum shall be refunded to the Company or credited to reduce
principal hereunder. All payments received by the Payee hereunder will be
applied first to costs of collection and fees, if any, then to interest, then to
principal and the balance to premium (if any).

<PAGE>

         All principal plus accrued and unpaid interest on the Note and premium
(if any) shall be immediately due and payable upon notice in writing from Payee
to the Company, without presentment, demand, protest, or notice, upon the
occurrence of an Event of Default of the type specified in Section 4.1 of the
Agreement, after taking account of all applicable grace and cure periods
thereunder. All accrued and unpaid interest on the Note and premium (if any)
shall be paid upon payment of the principal of the Note, whether by demand, or
upon acceleration as provided herein, or otherwise. At the time that the payment
of the balance of this Note becomes due, the Payee may proceed with every remedy
available at law or in equity.

         This Note is issued pursuant to and is entitled to the benefits of a
certain Note and Warrant Purchase Agreement, dated as of April 19, 2004, by and
among the Company and the purchaser named therein (the "Agreement"), the terms
of which are incorporated herein, and each holder of this Note, by his, her or
its acceptance hereof, agrees to be bound by the provisions of the Agreement,
including, without limitation, the representations contained in Section 1.9
thereof. Without limiting the foregoing, the holder of this Note is subject to
the mandatory equity conversion provisions as set forth in Section 1.10 of the
Agreement.

         Principal and interest shall be payable in lawful money of the United
States of America, at the address of the Payee set forth in the Agreement or at
such other address as the Payee or any subsequent holder may designate from time
to time to the Company in writing. If any day on which a payment is due pursuant
to the terms of this Note is not a Business Day (as such term is defined in the
Agreement), such payment shall be due on the next Business Day following.

         Upon surrender of this Note for transfer or exchange, a new note or new
notes of the same tenor dated the date to which interest has been paid on the
surrendered Note and in an aggregate principal amount equal to the unpaid
principal amount of the Note so surrendered will be issued to, and registered in
the name of, the transferor or transferees. The Company may treat the person in
whose name this Note is registered as the owner hereof for the purpose of
receiving payment and for all other purposes.

         In the event any one or more of the provisions of this Note shall for
any reason be held to be invalid, illegal or unenforceable, in whole or in part
or in any respect, or in the event that any one or more of the provisions of
this Note operate or would prospectively operate to invalidate this Note, then
and in any such event, such provision(s) only shall be deemed null and void and
shall not affect any other provision of this Note and the remaining provisions
of this Note shall remain operative and in full force and effect and in no way
shall be affected, prejudiced, or disturbed thereby.

         In case any payment herein provided for shall not be paid when due, the
Company promises to pay all costs of collection or enforcement of this Note,
including, without limitation, court costs and all reasonable attorney's fees
and expenses incurred or paid by the Payee in enforcing the obligations of the
Company.

<PAGE>

         This Note may be not be prepaid without the prior written consent of
the Payee.

         All notices to the Company and the Payee required or permitted
hereunder shall be made in accordance with the Agreement.

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

         Whenever used herein, the terms "Company" and "Payee" shall be deemed
to include, to the extent applicable, the successors and assigns of such
parties; provided, however, that the obligations of the Company under this Note
may not be assigned without the express written consent of the Payee or any
holder hereof, which consent may be withheld in the sole and absolute discretion
of such Payee or holder.

         The Company and all endorsers of this Note herein waive presentment,
notice of nonpayment, protest and all other demand and notices in connection
with the delivery, acceptance, performance or enforcement of this Note.

         If any part of this Note shall be adjudged invalid, illegal, or
unenforceable, then such partial invalidity, illegality, or unenforceability
shall not cause the remainder of this Note to be or to become invalid, illegal,
or unenforceable. If a provision hereof is held invalid, illegal or
unenforceable in one or more of its applications, the parties hereto agree that
the other provisions shall remain in effect in all valid, legal and enforceable
applications that are severable from the invalid, illegal or unenforceable
application or applications.

         The validity, meaning, enforceability and effect of this Note, and the
rights and liabilities of the parties, shall be determined in accordance with
the laws of the State of Delaware.
