                            PUBLIC OFFERING OF UNITS

                                ESCROW AGREEMENT

        THIS ESCROW AGREEMENT ("Agreement") is made and entered into as of this
___ day of March, 2006, by and among NEDAK Ethanol, LLC, a Nebraska limited
liability company ("Company"), and Great Western Bank, a Nebraska state banking
association ("Escrow Agent").

                                    RECITALS

        WHEREAS, the Company desires to effect a public offering ("Offering") of
up to 3,150 units ("Units") for cash; and

        WHEREAS, the Company wishes to make provision to deposit the
subscription proceeds received by the Company from the subscriptions for Units
in the Offering into an interest-bearing escrow account ("Escrow Account")
established with the Escrow Agent, which proceeds (including interest accrued
thereon) are to be delivered and paid to the Company only in the circumstances
hereinafter defined; and

        WHEREAS, the Company and the Escrow Agent desire to enter into an
agreement with respect to the above-described escrow arrangements.

        NOW, THEREFORE, in consideration of the foregoing and the mutual
promises and covenants contained herein, the parties hereby agree as follows:

        I. Delivery of Proceeds to Escrow Agent.

               (a) Subscription Proceeds. The Company agrees that it shall
        deliver to the Escrow Agent via insured overnight mail, courier or by
        similar acceptable means, immediately upon receipt thereof, all
        subscription proceeds from the subscription for Units in the Offering,
        together with a copy of each such subscriber's completed and executed
        Subscription Agreement. The Company will instruct subscribers to make
        checks for Unit subscriptions payable to the order of the Escrow Agent.
        Any checks received by the Escrow Agent that are made payable to a party
        other than as set forth above shall be returned to the Company for
        restrictive endorsement by the payee to the Escrow Agent. Upon approval
        of each subscription by the Company (but not prior thereto), the Escrow
        Agent is authorized to forward each subscription check received for
        collection and, upon collection of such check, to immediately deposit
        the collected proceeds in the Escrow Account.

        2.     Escrow Account

               (a) Deposits. Upon approval of each subscription by the Company,
        all subscription amounts delivered to the Escrow Agent pursuant hereto
        shall be deposited immediately by the Escrow Agent into the Escrow
        Account, subject to the investment thereof as set forth in Section 2(c)
        below. The Escrow Agent shall not forward subscription checks for
        collection or otherwise deposit subscription proceeds into the Escrow
        Account until receiving written confirmation from the Company or its
        legal counsel that the subscriber has been approved by the Company.

               (b) Deposit Record. The Escrow Account shall be created and
        maintained subject to the customary rules and regulations of the Escrow
        Agent pertaining to such accounts. The Escrow Agent shall at all times
        maintain a record ("Deposit Record") of the names and addresses of
        subscribers, the amount of Units subscribed thereby and the aggregate
        amount of funds paid therefor as deposited with the Escrow Agent. Copies
        of such Deposit Record shall be made available upon the Company's
        request during the Escrow Period.

               (c) Investment of Funds. All deposits held in the Escrow Account
        by the Escrow Agent shall be invested thereby in any of the following
        investment vehicles, at the discretion of the Escrow Agent: (i) money
        market mutual funds; or (ii) short-term United States Government
        Treasury securities, notes or bills; or (iii) short-term certificates of
        deposit issued by a bank.

        3. Escrow Period. The escrow period ("Escrow Period") shall begin on the
date hereof and shall terminate on the earlier of:

               (a) Prior to Offering Completion. The release and return of all
        deposited subscription proceeds (including accrued interest thereon) to
        subscribers, in the event the Company decides, in its sole discretion,
        to terminate the Offering prior to, or if the Company has not certified
        to the Escrow Agent that it has raised at least Twenty Million Dollars
        ($20,000,000) by, the Offering Completion Date (July 1, 2006);

               (b) Upon Expiration Date. The release and return of all deposited
        subscription proceeds (including accrued interest thereon) to
        subscribers, upon the failure of the Company to certify to the Escrow
        Agent that it has received a commitment from a lender (the "Loan
        Commitment") sufficient to permit the Company to proceed to build its
        proposed ethanol plant, by September 30, 2006 (the "Expiration Date");
        or

               (c) Closing. The completion of the Offering upon the subscription
        for at least Twenty Million Dollars ($20,000,000) of Units on or before
        the Offering Completion Date and receipt of the Loan Commitment on or
        before the Expiration Date (the "Closing").

        4. Payment of Escrowed Funds to the Company. At the Closing, the Escrow
Agent shall remit by certified check, or wire transfer to the Company, the
proceeds received, collected and deposited in the Escrow Account from the
subscription for Units delivered by the Company to the Escrow Agent, including
all interest accrued thereon. At least three (3) business days prior to the
Closing, the Company shall deliver to the Escrow Agent directions regarding the
amount of proceeds to be paid to it. At such time as the Escrow Agent shall have
made all the payments, deliveries and remittances provided for in this Section
4, if any, the Escrow Agent shall be completely discharged and released of any
and all further liabilities and responsibilities hereunder. The date on which
the Closing shall occur pursuant to this Section 4 shall sometimes be referred
to as the "Escrow Closing Date."

        5. When Funds Repaid to Subscribers. In the event the Escrow Period
terminates because Twenty Million Dollars ($20,000,000) of offered Units have
not been subscribed for or the Loan Commitment is not received on or before the
Expiration Date or the Company terminates the Offering prior to the Offering
Completion Date then the Escrow Agent as promptly as practicable, but not more
than one (1) month thereafter, and on the basis of its Deposit Record, shall
return directly to each of the subscribers the respective amounts paid in by
them as their subscription for Units, including all respective interest accrued
thereon pursuant to the investment of such funds by the Escrow Agent under
Section 2(c) without any deductions therefrom. Each amount paid or payable to
each subscriber pursuant to this Section 5 shall be deemed to be the property of
each subscriber, free and clear of any and all claims of the Company, or of any
of their respective creditors, and the respective Subscription Agreements
evidencing subscriptions for Units made and entered into by such subscribers in
the Offering shall thereupon be automatically deemed, without further deed or
action, to be cancelled without any further liability of such subscribers to pay
for the Units subscribed. At such time as the Escrow Agent shall have made all
the payments, deliveries and remittances provided for in this Section 5, if any,
the Escrow Agent shall be completely discharged and released of any and all
further liabilities and responsibilities hereunder.

                                      X-2

        6. Escrowed Funds Not Property of the Company. During the Escrow Period,
all amounts deposited (or accrued) in the Escrow Account shall not become the
property of the Company or obligations of the Company, and the Escrow Agent
shall make or permit no disbursements or other transfers from the Escrow
Account, except as expressly provided herein.

        7. Notice to Escrow Agent. The Company agrees to give to the Escrow
Agent appropriate written notice of the date upon which the Offering is
commenced, as soon as practicable thereafter, and appropriate written notice of
the Offering Completion Date, or the date on which the Company terminates the
Offering, as the case may be.

        8. Rejection of Subscription. In the event that a subscriber is rejected
by the Company for any reason, the Escrow Agent shall, upon written direction
received from the Company, return all subscription funds received from such
subscriber with respect to any subscription by such rejected subscriber, without
deduction (but without interest), directly to such subscriber.

        9. Miscellaneous. The Escrow Agent shall:

               (a) No Other Duty. Be under no duty to enforce payment of any
        subscription which is to be paid to, and held by, it hereunder other

               (e) Giving of Notice. Be deemed conclusively to have given and

        mailed, by registered or certified mail, return receipt requested,
        postage prepaid, addressed to the Company at the respective addresses
        set forth above (or otherwise mailed by overnight courier, telecopied,
        telefaxed or personally delivered thereto);

               (f) Counsel. Be permitted to consult with legal counsel of its
        choice, including in-house counsel, and shall not be liable for any
        action taken, suffered or omitted by it in accordance with the
        reasonable advice of such counsel; provided, however, that nothing
        contained in this Section 9(f), or omitted by it in accordance with the
        reasonable advice of any counsel, shall relieve the Escrow Agent from
        liability for any claims which are occasioned by its bad faith, gross
        negligence or willful misconduct.

        as to its duties or rights hereunder or shall have received
        instructions, claims or demands from any of the other parties hereto
        which, in its opinion, are in conflict with any of the provisions of
        this Agreement or with instructions given by another party, it shall be
        entitled to refrain from taking any action other than to keep all
        property held by it in the Escrow Account until it shall be directed
        otherwise in writing by all of the other parties hereto or by a final
        judgment by a court of competent jurisdiction;

hereunder, including any liability for any material misstatements or omissions
of material facts set forth in the Offering Memorandum and/or any litigation

                               NEDAK ETHANOL, LLC
                                       AND
                               DELTA-T CORPORATION

        THIS AGREEMENT is entered into and becomes effective as of the 15 day of
November, 2005 (the "Contract Date"), by and between Delta-T Corporation, a
corporation organized and operating under the laws of the Commonwealth of
Virginia, USA located at 323 Alexander Lee Parkway, Williamsburg, Virginia 23185
("DTC"), and NEDAK ETHANOL LLC, a company organized and operating under the laws
of NEBRASKA located at 302 NORTH MAIN STREET, P. O. BOX 391, ATKINSON, NEBRASKA
68713 ("Client"), which parties may be referred to individually as a "Party" or
jointly as the "Parties."

                                   WITNESSETH

        WHEREAS, Client intends to develop, own and operate an ethanol plant
having the capacity to produce 30 MILLION GALLONS PER YEAR (hereinafter the
"Plant") at a site to be located in HOLT COUNTY, NEBRASKA (hereinafter the
"Site"); and

        WHEREAS, DTC is in the business of developing, designing, and supplying
commercial technologies, equipment and manufacturing facilities to perform a
wide range of process industry applications, including, without limitation,
grain processing, ethanol production, evaporation, distillation, dehydration,
adsorption, solvent recovery and waste treatment; and

        WHEREAS, DTC has entered into a strategic alliance with TIC - The
Industrial Company, a Delaware corporation, located at 2211 Elk river Road,
Steamboat Springs, Colorado 80477 (hereinafter "TIC"), that is in the business
of providing construction and certain additional engineering services, for the
purpose of providing complete design/build services; and

        WHEREAS, Client wishes to retain DTC to provide professional advice,
business and technical information, design and engineering, and related services
in order to assist Client in assembling all of the information, permits,
agreements and resources necessary to complete project development, obtain
financing and proceed with construction of the Plant (hereinafter "Project"),
and DTC is willing to provide such services for a fixed fee, provided that
Client enters into an exclusive relationship with DTC to design and build the
Plant through an Engineering, Procurement and Construction Contract ("EPC
Contract") under which a mutually agreed upon general contractor or TIC (or DTC)
will perform construction and certain other services, and on the terms and
conditions set forth herein; and

        WHEREAS, Client recognizes that DTC is foregoing other significant
business opportunities in order to provide such services and that the payments
to be made to DTC under this Agreement are inadequate to fairly compensate DTC
for the services to be provided and that DTC is agreeing to perform such
services in exchange for the right to enter into the EPC Contract, and that the
provisions of this Agreement concerning exclusivity are essential to this
Agreement and that DTC would not be willing to enter into this Agreement without

<PAGE>

Client, or Owner, shall perform such tasks within sufficient time to allow DTC

require it to perform the obligations of Client described in this Agreement, and
shall assist DTC in causing such Owner to become a party to this Agreement, or
another similar agreement acceptable to DTC, and that Client shall not
participate in any way with any Owner toward development of the Plant unless
Owner has done so. Client agrees that it shall not assist Owner in any way,
directly or indirectly, in working with anyone other than DTC in connection with
the Project, except as expressly permitted under this Agreement. Client

did not have control, that such Owner would benefit significantly from such
information, and Client acknowledges that it understands and will comply
strictly with the prohibitions on such disclosures as set forth in Article II

DTC may accept. Client shall provide a copy of each such agreement to DTC and
TIC promptly upon execution of the same and prior to the disclosure of any

the receiving Party of this Agreement, or violation by any other party of an
obligation not to disclose it; or (c) the information is disclosed to the
receiving Party by a third party who is under no obligation not to disclose it.

2.5 OBLIGATIONS: The provisions of this Article II shall survive termination of
this Agreement until such time, if ever, that such information falls under one
or more of the exclusions set forth in Section 2.4 above. Each Party providing
Confidential Information pursuant to the terms of this Agreement shall have the
right to enforce the terms of this Agreement directly against any party.

                                   ARTICLE III
                 LIMITED LICENSE OF DTC CONFIDENTIAL INFORMATION

DTC is, and shall remain, the sole owner of the Confidential Information
provided by DTC under the terms of this Agreement. DTC hereby grants Client a
limited, non-exclusive, non-transferable license, without right to sublicense,
to use the provided Confidential Information solely for Client's use in
connection with the development and financing of the Project during the term of
this Agreement. DTC reserves to itself all rights not expressly granted under
this Article III. In particular, but without limitation, the license granted by
the terms of this Article DOES NOT INCLUDE the right to use any of the
Confidential Information to procure bids for the development, design or
construction of the Plant or any aspect of the Plant, or to design or operate
any other plant or facility based, in whole or in part, on any of such
Confidential Information, or to assist Owner in developing the Plant unless
Owner has become a party to this Agreement, or a similar agreement with DTC.

                                   ARTICLE IV
                                  COMPENSATION

4.1 STAGE II SERVICES: For the Stage II Services, as described in Section 1
above, Client shall pay DTC a fixed fee of Six Hundred Thousand Dollars
($600,000). Client shall pay to DTC the first Three Hundred Thousand Dollars
($300,000) of such fee upon issuance of its notice to proceed to DTC, as set
forth in Section 1 above. Client shall thereafter pay to DTC One Hundred

                                       4
<PAGE>

Thousand Dollars ($100,000) thirty (30) days after issuance of its notice to
proceed to DTC, One Hundred Thousand Dollars ($100,000) thirty (30) days after
that, and the remaining One Hundred Thousand Dollars ($100,000) ten (10) days
after delivery by DTC of a complete EPC Contract draft, as provided in Section 1
above. Failure to reach final agreement by the Parties with respect to terms and
conditions contained in the EPC Contract shall not be deemed a failure to
provide such a draft EPC Contract or relieve Client from payment of such final
payment. In addition to the foregoing, Client shall bear the cost of all travel,
room and board and related expenses incurred by DTC in connection with providing
such Stage II Services, with reimbursements based on actual costs.

4.2 LATE PAYMENT PENALTY: Client shall pay DTC a late charge at the lesser of
one percent (1%) per month or the highest amount permitted by applicable law on
all payments past due.

                                    ARTICLE V
                 EPC CONTRACT, EXCLUSIVITY AND BREAKAWAY DAMAGES

5.1 EPC CONTRACT: As soon as reasonably possible after a firm financing
commitment is received by Client, or at such earlier time as Client and DTC may
agree, Client and DTC shall enter into an EPC Contract pursuant to which DTC
shall provide the entire Plant under mutually agreeable terms. For purposes of
clarity and understanding between the Parties, which is hereby acknowledged, the
terms of the EPC Contract shall be based upon the Plant specifications, scope of
work definitions and commercial terms set forth in Exhibit A.

5.2 EXCLUSIVITY: During the term of this Agreement, Client shall not, and shall
not permit Owner or any other party associated with the Project, to enter into,
negotiate toward, or take any other action in furtherance of entering into any
agreement by which any other party would provide the technology, engineering,
construction, or equipment procurement services to be provided by DTC under this
Agreement or under the EPC Contract.

5.3 BREAKAWAY DAMAGES: If, during the term of this Agreement, or within Seven
Hundred Twenty (720) days after the termination of this Agreement, Client or
Owner begins the design and/or construction of the Plant without entering into
an EPC Contract with DTC or enters into any agreement with any other party to
provide the technology, engineering, construction or equipment procurement
services of all or any portion of the Project, Client shall pay a liquidated
damage amount to DTC in the amount of five percent (5%) of the Price set forth
in Section 5.2 above (hereinafter the "Breakaway Damages"). Such fee shall be
due and payable within thirty (30) days of the earliest of when Client shall
enter into an agreement with a third party for the provision of technology,
engineering, construction or equipment procurement services for the Project or
any form of such services related to the Project shall commence. The Parties
acknowledge and agree that because of the unique nature of the services to be
provided pursuant to this Agreement, it is difficult or impossible to determine
with precision the amount of damages that would or might be incurred by DTC as a
result of Client's election not to enter into an EPC Contract with DTC to
provide complete design/build services for the Plant and that an election by
Client to proceed with the Project without entering into such an agreement with
DTC will cause damage to DTC which may be difficult or impossible to determine
with precision; and that any sums which would be payable under this Section 5.4
are in the nature of liquidated damages, and not a penalty, and are fair and
reasonable and such payment represents a reasonable estimate by the Parties of
fair compensation for the losses that may reasonably be anticipated from such
termination.

                                   ARTICLE VI
                             INDEPENDENT CONTRACTOR

Nothing in this Agreement shall be deemed to make either Party an agent or
partner of the other, or to give either Party the right to bind the other in any
way.

                                   ARTICLE VII
                              TERM AND TERMINATION

This Agreement shall commence on the Contract Date and shall continue for a
period of five (5) years unless earlier terminated as provided in this Article
VII. This Agreement may be terminated:

     (a)  at the election of the non-breaching Party, after giving thirty (30)
          days written notice of a material breach of this Agreement, if such
          breach is not cured within such 30-day period, or such longer time as
          is reasonably necessary to cure such breach;
     (b)  at the election of DTC, at any time after one (1) year from the
          Contract Date, if Project financing has not been obtained by that
          date, and provided that notice of termination is given prior to the
          date on which Financing for the Project is obtained;
     (c)  upon the mutual agreement of the Parties;
     (d)  upon the execution of an EPC Contract; or
     (e)  upon payment to DTC of the Breakaway Damages pursuant to the terms of
          Section 5.4 above.

Upon termination of this Agreement for any reason, the license granted under
Article III above shall immediately cease, and each Party shall (i) immediately
cease use of all Confidential Information provided by the other, (ii)
immediately deliver to the disclosing Party all Confidential Information
provided to it, including all copies of the same, and destroy all materials
developed by it or any third parties to whom it disclosed such information which
was based upon such information, and (iii) certify to the disclosing Party that
it has done so. In particular, but without limitation, Client shall promptly
advise all actual and potential investors and lenders for the Project and all
regulatory authorities to which Confidential Information provided to Client
under the terms of this Agreement was previously provided, of the termination of
this Agreement, and shall withdraw any applications for financing or permits
that were based on the use of such Confidential Information.

                                  ARTICLE VIII
                               DISPUTE RESOLUTION

In the event of any dispute arising under or in connection with this Agreement
or with the existence, validity, interpretation, breach or enforcement thereof,
either before or after the termination or expiration of this Agreement, the
Parties shall, upon the written request of either of them, enter into mediation
of such dispute pursuant to the applicable rules of the American Arbitration
Association, or such other rules or procedures as they may agree. Neither Party
shall file suit unless it has first complied with this provision and attempted
to resolve such dispute for a period of at least thirty (30) days. Nothing
contained herein, however, shall be deemed to prevent either Party from seeking
injunctive relief from any court of competent jurisdiction, without necessity of
posting bond, in case of a breach of Articles II or III above. If any action at
law or in equity, including an action for declaratory relief, is brought to
enforce or interpret the provisions of this Agreement, the prevailing Party
shall be entitled to recover reasonable attorney's fees and costs from the other
Party, which fees and costs may be set by the court in the trial of such action,
or may be enforced in a separate action and brought for that purpose, and which
fees and costs shall be in addition to any other relief which may be afforded.

                        LIMITATION OF DAMAGES AND REMEDY

Client's sole remedy with respect to any uncured breach by DTC of any provision
of this Agreement (other than a breach of Article II), including, without
limitation, any breach with respect to services performed by DTC under Section
1, shall be the termination of this Agreement and, for purposes of services
provided under Section 1 above, the refund to Client of the portion of the
compensation payable to DTC pursuant to the terms of Section 4.2 above, if any,
allocable to services not properly performed. In no case shall DTC be liable for
any other damages of any kind, whether direct, indirect, incidental,
consequential, reliance, exemplary or otherwise, with respect to any services
performed by it, or to its failure to perform services, under this Agreement.

                                    ARTICLE X

                                    EXHIBIT A
          PLANT SPECIFICATIONS, SCOPE OF SERVICES AND COMMERCIAL TERMS
                               BASELINE TERM SHEET

This Term Sheet contains the basic terms upon which DTC and Client (each of
which may be referred to as a "Party" or jointly as "Parties") agree to
negotiate a complete design/build Engineering, Procurement and Construction
Contract ("EPC Contract") pursuant to Section 5.1 of the Agreement. Neither DTC
nor Client shall have any legally binding obligations or liabilities to the
other under this Term Sheet, including but not limited to a legal duty to
continue negotiations or to reach a definitive agreement. No other binding
obligations or rights will be created, implied or inferred, until a definitive
EPC Contract that is mutually acceptable to the Parties is fully executed by
both Parties.

A.1     BASE CONTRACT PROJECT DESCRIPTION, BATTERY LIMITS AND APPROACH:

        A.1.1 PROJECT DESCRIPTION: The Plant will be a dry mill ethanol plant
        with a design capacity of 30 million gallons per year of undenatured
        anhydrous ethanol, with a design basis for operating twenty-four (24)
        hours per day for three hundred fifty (350) days per year.

        A.1.2 SCOPE BATTERY LIMITS: The baseline scope battery limits of the
        Plant will be comprised of:

               A.1.2.1INSIDE BATTERY LIMITS: The Inside Battery Limits ("IBL")
               scope for the Project includes the scope items that DTC typically
               provides from project to project. Such items are indicated in the
               Project Scope Overview, Section A.3 of this Exhibit A, as being
               provided by "DELTA-T". Such items are the basis upon which the
               Price for the EPC Contract, as set forth in Section 5.1, is
               determined.

               A.1.2.2OUTSIDE BATTERY LIMITS: The Outside Battery Limits ("OBL")
               scope for the Project are the scope items that Client or Owner
               often prefers to provide, at its discretion. Such items are
               indicated in the Project Scope Overview, Section A.3 of this
               Exhibit A, as being provided by "CLIENT". Exclusion of such items
               is the basis upon which the Price for the EPC Contract, as set
               forth in Section 5.1, is determined.

        The Parties may agree to shift items from IBL to OBL or vice versa
        during discussions, finalization efforts regarding Plant specifications
        and design, and during final EPC Contract negotiations.

        A.1.3 PROJECT APPROACH: DTC shall act as the Prime Contractor on the
        Project with subcontractor(s) performing all construction services
        necessary to construct the Plant for a fixed fee.

               A.1.3.1Unless specifically noted otherwise, DTC's basis of design
               assumes conformance to the applicable sections and parts of the
               codes and standards set forth below, including the most recent
               revisions and supplements at the time of the execution of the EPC
               Contract.

        reasonable steps to protect Confidential Information from improper use
        or disclosure, and shall in no case use less care to protect
        Confidential Information than it uses to protect its own proprietary or
        confidential information.

        2.2 DISCLOSURES REQUIRED BY COURT ORDER: If any Recipient is required to
        disclose any Confidential Information by applicable law, regulation or
        legal process, Recipient shall notify Company of such request or
        requirement and copies of all documents relevant to the request or
        requirement. Recipient shall give such notice promptly, and in
        sufficient time to allow Company to seek a protective order or other
        applicable remedy. Recipient shall not disclose any Confidential
        Information due to a requirement of law, regulation or legal process
        unless: (a) it has first given the notice required by this Section 2.2
        and Company has either given Recipient written permission to disclose
        it, or Company has failed to respond to Recipient's notice at least 24
        hours prior to the time that Recipient is required to make such
        disclosure; (b) it is advised by written opinion of its counsel that it
        is legally required to disclose such information; and (c) it has used
        its best efforts to obtain all reasonable assurances from the party or
        parties to whom the information is to be disclosed that the information
        will not be used or disclosed for any purpose other than the purpose for
        which the applicable law, regulation or legal process requires its
        disclosure.

3. DESIGNATION OF PERSON WITH ADMINISTRATIVE RESPONSIBILITY: Recipient shall
designate one of its employees or representatives to be responsible for
fulfilling its obligations under this Agreement and shall advise Company in
writing of such employee's name and title within four (4) business days of any
change of such designation. Until further notice, the individual so designated
is as follows:

    NAME              ________________________
    TITLE             ________________________

4. TERM AND TERMINATION: The term of this Agreement shall commence on the date
first written above and continue until terminated by written notice of either
Party to the other, but Recipient's obligations under Section 2 of this
Agreement shall survive until such time, if ever, that the Confidential
Information falls within one or more of the exclusions set forth at Section 1.2
above. Within thirty (30) calendar days of termination of this Agreement,
Recipient shall, without request by Company, deliver to Company all of the
Confidential Information that it received from Company in tangible form, and all
copies thereof, and shall destroy all documents and other tangible items
containing any of such Confidential Information and shall certify to Company in
writing that it has done so.

5. NO LICENSE OR OTHER RIGHTS: Nothing in this Agreement shall constitute or
otherwise be construed as granting to Recipient any interest or license in any
Confidential Information, or creating any obligation on the part of any Party
hereto to enter into any further agreement or business arrangement.

6. REMEDIES FOR BREACH: Recipient agrees that any breach of this Agreement shall
cause Company irreparable harm. Accordingly, and in addition to any other
remedies that Company may have at law or in equity, Company shall be entitled to
obtain injunctive relief against Recipient to prevent any continuing breach, and
without posting or filing any bond or other security. All costs, expenses and
attorney's fees resulting from the litigation or arbitration of any claim under
this Agreement shall be paid by the losing party to the prevailing party.

U.S. Export license provisions, no technical information furnished to it
hereunder shall be disclosed by it to any non-U.S. national, firm, or country,
including foreign nationals employed by or associated with such party, nor shall
such party allow any re-export of any technical information without first
complying with all applicable U.S. Government export control laws and
regulations.
