2.     TYPES  OF  REGISTRATION  RIGHTS
       -------------------------------
       2.1     PIGGYBACK
               ---------
     (a)  If  Issuer  at any time proposes for any reason to register its common
stock  under  the Securities Act (other than on Form S-4 or Form S-8 promulgated
under the Securities Act or any successor forms thereto), it shall promptly give
written  notice  to  each Permitted Right Holder of its intention so to register
its  common  stock  and, upon the written request, given within 10 business days
after  delivery  of  any such notice by Issuer, of any Permitted Right Holder to
include in such registration Registrable Securities (which request shall specify
the  number  of  Registrable  Securities  proposed  to  be  included  in  such
registration),  Issuer  shall  use  its  commercially reasonable best efforts to
cause all such Registrable Securities to be included in such registration on the
same  terms  and  conditions  as  the  securities  otherwise  being sold in such
registration;  provided  that  if,  at  any  time  after  written  notice of its
intention to register any offering of securities and prior to the effective date
of the registration statement filed in connection with such registration, Issuer
will determine for any reason either not to register or to delay registration of
such  securities,  Issuer  may,  at  its  election,  give written notice of such
determination  to each Permitted Right Holder and, thereon, (i) in the case of a
determination  not  to register, will be relieved of this obligation to register
any  Registrable  Securities  in connection with such registration (but not from
the  obligation  to  pay the Registration Expenses in connection therewith), and
(ii)  in  the case of a determination to delay registering, will be permitted to
delay  registering  any Registrable Securities, for the same period as the delay
in  registering  such  other  securities. The right provided the Permitted Right
Holders  of  the  Registrable  Securities  pursuant  to  this  section  will  be
exercisable  at  their  sole  discretion  upon  the execution of this Agreement.

     (b)  If  Issuer  fails  to  propose  to register its common stock under the
Securities  Act  (other  than  on  Form  S-4  or  Form S-8 promulgated under the
Securities  Act  or  any  successor  forms thereto) within 30 days following the
initial  closing  of  its offering of Series A Convertible Preferred Stock, then
Issuer  shall  nevertheless  use  its  best  efforts  to  effect,  as  soon  as
practicable,  the  registration  under  the  Securities  Act  of all Registrable
Securities  that  the  Permitted  Right Holders request to be registered. If the
initial closing of Issuer's offering of Series A Convertible Preferred Stock has
not  occurred by September 30, 2002, then Issuer shall nevertheless use its best
efforts to effect, as soon as practicable, the registration under the Securities
Act of all Registrable Securities that the Permitted Right Holders request to be
registered.

3.     PROCEDURE
       ---------
OBLIGATIONS  OF ISSUER.  Whenever required to effect the
        ----------------------
registration  of  any Registrable Securities under Section 2.1, Issuer shall, as
expeditiously  as  possible:

     (a)  prepare  and  file with the SEC a registration statement or amendments
thereto,  to  effect  such  registration  (including  such  audited  financial
statements as may be required by the Securities Act or the rules and regulations
promulgated  thereunder)  and  thereafter  use  its commercially reasonable best
efforts  to  cause  a  registration  statement  that  registers such Registrable
Securities  to  become  and remain effective for 180 days or until the Permitted
Right  Holders have completed the distribution related thereto, whichever occurs

                                     Page 2
<PAGE>

first.  If requested by the Permitted Right Holders, Issuer shall file, cause to
become  effective  or  maintain  the effectiveness of any registration statement
that  contemplates a distribution of securities on a delayed or continuous basis
pursuant  to  Rule  415  under  the  Securities Act and subject to the same time
constraints  as  provided  in  the  preceding  sentence.

     (b)  prepare  and file with the SEC such amendments and supplements to such
registration statement and the prospectus used in connection therewith as may be
necessary  to  comply  with the provisions of the Securities Act with respect to
the disposition of all securities covered by such registration statement for the
period  set  forth  in  paragraph  (a)  above.

     (c)  notify,  in  writing,  each Permitted Right Holder promptly (A) of the
receipt  by  Issuer  of any notification with respect to any comments by the SEC
with  respect  to  such registration statement or prospectus or any amendment or
supplement  thereto  or any request by the SEC for the amending or supplementing
thereof  or  for additional information with respect thereto, (B) of the receipt
by  Issuer  of  any  notification with respect to the issuance by the SEC of any
stop  order  suspending  the  effectiveness  of  such  registration statement or
prospectus  or  any  amendment  or  supplement  thereto  or  the  initiation  or
threatening  of any proceeding for that purpose and (C) of the receipt by Issuer
of  any notification with respect to the suspension of the qualification of such
Registrable  Securities  for  sale  in  any  jurisdiction  or  the initiation or
threatening  of  any  proceeding  for  such  purpose;

     (d) use its best efforts to register or qualify such Registrable Securities
under  such  other  securities  or "blue sky" laws of such jurisdictions as each
Permitted  Right  Holder  reasonably  requests and do any and all other acts and
things  which  may  be reasonably necessary or advisable to enable the Permitted
Right  Holders  to  consummate  the  disposition  in  such  jurisdictions of the
Registrable Securities owned by such Permitted Right Holders; provided, however,
that  Issuer  will  not be required to qualify generally to do business, subject
itself  to  general  taxation  or  consent  to general service of process in any
jurisdiction  where  it  would  not  otherwise be required so to do but for this
paragraph;

     (e)  furnish  to  each  Permitted  Right  Holder such number of copies of a
summary  prospectus  or other prospectus, including a preliminary prospectus, in
conformity with the requirements of the Securities Act, and such other documents
as such Permitted Right Holder may reasonably request in order to facilitate the
public  sale  or  other  disposition  of  such  Registrable  Securities;

     (f)  make  available  for  inspection  by  any  Permitted Right Holder, any
underwriter  participating  in  any  disposition  pursuant  to such registration
statement  and  any  attorney,  accountant  or  other agent retained by any such
Permitted  Right  Holder  or  underwriter  (collectively, the "Inspectors"), all
pertinent  financial  and  other  records,  pertinent  corporate  documents  and
properties  of  Issuer  (collectively,  the  "Records"),  as shall be reasonably
necessary  to  enable  them  to exercise their due diligence responsibility, and
cause  Issuer's  officers,  directors  and  employees  to supply all information
(together  with the Records, the "Information") reasonably requested by any such
Inspector in connection with such registration statement. Any of the Information
which  Issuer  determines  in  good  faith  to  be  confidential,  and  of which

                                     Page 3
<PAGE>

determination  the  Inspectors  are  so  notified, shall not be disclosed by the
Inspectors  unless  (A) the disclosure of such Information is necessary to avoid
or  correct  a  misstatement  or omission in the registration statement, (B) the
release  of  such  Information  is ordered pursuant to a subpoena or other order
from  a  court  of  competent jurisdiction or (C) such Information has been made
generally available to the public without breach of any duty of confidentiality.
The  Permitted Right Holders agree that they will, upon learning that disclosure
of  such Information is sought in a court of competent jurisdiction, give notice
to Issuer and allow Issuer, at Issuer's expense, to undertake appropriate action
to  prevent  disclosure  of  the  Information  deemed  confidential;

     (g)  use  its  commercially reasonable best efforts to list all Registrable
Securities  covered  by the registration statement on any securities exchange on
which  any  of  the  Registrable  Securities  are  then  listed;  and

     (h)  use  its  commercially reasonable best efforts to take all other steps
necessary to effect the registration of such Registrable Securities contemplated
hereby.

3.2     EXPENSES  OF  REGISTRATION.  Except as specifically provided herein, all
        --------------------------
Registration  Expenses  incurred  in  connection  with  any  registration,
qualification  or  compliance  pursuant  to Section 2.1 herein shall be borne by
Issuer.  All  Selling  Expenses  incurred  in  connection with any registration,
qualification  or  compliance  pursuant  to  Section  2.1  shall be borne by the
Permitted  Right  Holders.  Issuer  shall  not,  however, be required to pay the
Registration  Expenses  of any registration proceeding begun pursuant to Section
2.1, the request of which has been subsequently withdrawn by the Permitted Right
Holders  unless  the  withdrawal is based upon material adverse information
concerning  Issuer  of  which  the Permitted Right Holders were not aware at the
time  of  such  request.  If the Permitted Right Holders are required to pay the
Registration  Expenses  of  a  withdrawn  offering  pursuant  to  the  preceding
sentence,  until such time as all the expenses have been paid to Issuer in full,
the Permitted Right Holders shall forfeit their right pursuant to Section 2.1 to
participate  in  piggyback  registration.  If  Issuer  is  required  to  pay the
Registration  Expenses of a withdrawn offering, then the Permitted Right Holders
shall  not  forfeit  their  right  pursuant  to  Section  2.1  to participate in
piggyback  registration.

3.3     COUNSEL  FEES.  In connection with any registration of an offering under
        -------------
this  Section 3, if there is more than one Permitted Right Holder, the Permitted
Right  Holders  shall  designate one counsel for the Permitted Right Holders who
shall  be  authorized  to represent the interests of the Permitted Right Holders
with  respect to Issuer and the underwriter in connection with the offering.  If
the  Permitted  Right Holders are unable to designate one counsel after a period
of  30  days, Issuer may solicit suggestions for such counsel from the Permitted
Right  Holders  (no  more  than  one suggestion per Permitted Right Holder), and
select one counsel from among those suggested, and the selection of such counsel
shall  be binding on the Permitted Right Holders.  The fees and expenses of
counsel  for  the Permitted Rights Holders shall be paid by the Permitted Rights
Holders.

3.4     RIGHT  TO  DEFER REGISTRATION.  Issuer shall not be required to effect a
        -----------------------------
registration  pursuant  to  Section 2.1 if Issuer shall furnish to the Permitted
Right  Holders a certificate signed by the Chairman of the Board stating that in

                                     Page 4
<PAGE>

the  good  faith  judgment  of  the  Board  of  Directors of Issuer, it would be
materially  detrimental  to  Issuer  and  its shareholders for such registration
statement  to  be  effected  at  such time, in which event Issuer shall have the
right  to  defer  such  filing  for a period of not more than one hundred twenty
(120)  days  after receipt of the request pursuant to Section 2.1; provided that
such right to delay a request shall be exercised by Issuer not more than once in
any  twelve  (12)  month  period.

4.     TERMINATION  OF  REGISTRATION  RIGHTS.  All  registration  rights granted
       -------------------------------------
under  this  Agreement,  and  all  notices  required under this Agreement, shall
terminate  and  be  of  no further force and effect on the date that is one year
after  the grant of the Option; provided, however, that if a registration of the
Registrable  Securities has not been declared effective by such date, the rights
granted  hereunder  shall not terminate until a registration statement including
the  Registrable  Securities  has  been  declared  effective.

5.     REQUESTS  FOR  INFORMATION.  The  Permitted Right Holders hereby agree to
       --------------------------
promptly  furnish  Issuer  with  any  and all written information concerning the
Permitted  Right Holders that Issuer reasonably requests in order to (1) prepare
the  registration  statements and (2) conduct such other due diligence as may be
necessary  for  Issuer  to  satisfy or respond to any regulatory or governmental
requirements  or  requests.  The  Permitted Right Holders agree to provide true,
complete  and  accurate  information  based  on a diligent review of appropriate
records  as  would  be  conducted  by a prudent man in the management of his own
property.  The  Permitted  Right  Holders understand that Issuer may incorporate
some  or  all  of such information into the foregoing documents or may determine
based  on  such  information that certain disclosures are not required, and that
Issuer  will depend on the Permitted Right Holders to provide true, complete and
accurate  information.

6.     DELAY  OF  REGISTRATION.  The  Permitted Right Holders shall not have the
right to obtain or seek an injunction restraining or otherwise delaying any such
registration  as  the result of any controversy that might arise with respect to
the  interpretation  or  implementation  of  this  Agreement.

7.     INDEMNIFICATION.  In the event any Registrable Securities are included in
       ---------------
a  registration  statement  under  Section  2:

     7.1  Issuer  agrees  to  indemnify  and  hold harmless each Permitted Right
Holder and each person, if any, who controls a Permitted Right Holder within the
meaning  of  the  Securities  Act  against  any  losses,  claims,  damages  or
liabilities,  joint or several (which shall, for all purposes of this Agreement,
include,  but  not  be  limited  to,  all  reasonable  costs  of  defense  and
investigation  and  all  reasonable attorneys' fees), to which a Permitted Right
Holder may become subject under the Securities Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of  or  are  based  upon any untrue statement or alleged untrue statement of any
material  fact  contained  in  the  registration  statement,  or  amendments  or
supplements  thereto,  or arise out of or are based upon the omission or alleged
omission  to  state  therein  a  material  fact required to be stated therein or
necessary to make the statements therein not misleading; provided, however, that
Issuer  will  not  be  liable in any such case to the extent that any such loss,
claim, damage or liability arises out of or is based upon an untrue statement or
alleged  untrue  statement  or  omission  or  alleged  omission  in  any  of the
above-mentioned  documents  in  reliance  upon,  and in conformity with, written
information furnished to Issuer by a Permitted Right Holder specifically for use

                                     Page 5
<PAGE>

in  the preparation thereof. This indemnity agreement will be in addition to any
liability  that  Issuer  may  otherwise  have.

     7.2  Each  Permitted  Right  Holder  agrees that it will indemnify and hold
harmless  Issuer,  and  each  officer, director of Issuer or person, if any, who
controls  Issuer  within  the meaning of the Securities Act, against any losses,
claims, damages or liabilities (which shall, for all purposes of this Agreement,
include,  but  not  be  limited  to,  all  reasonable  costs  of  defense  and
investigation  and  all  reasonable attorneys' fees) to which Issuer or any such
officer,  director or controlling person may become subject under the Securities
Act  or  otherwise,  insofar  as such losses, claims, damages or liabilities (or
actions  in respect thereof) arise out of or are based upon any untrue statement
or  alleged  untrue statement of any material fact contained in the registration
statement,  or  amendments  or supplements thereto, or arise out of or are based
upon  the  omission  or  the  alleged  omission to state therein a material fact
required  to  be  stated therein or necessary to make the statements therein not
misleading,  but  in  each case only to the extent that such untrue statement or
alleged  untrue  statement  or  omission  or  alleged  omission  was  made  the
registration statement or amendments or supplements thereto in reliance upon and
in  conformity  with, written information furnished to Issuer by Permitted Right
Holders  specifically  for  use  in  the  preparation  thereof.  This  indemnity
agreement  will be in addition to any liability that the Permitted Right Holders
may  otherwise  have.

     7.3  Promptly  after receipt by an indemnified party under this Section 7.3
of  notice  of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under this
Section  7,  notify  the indemnifying party of the commencement thereof; but the
omission  so  to notify the indemnifying party will not relieve the indemnifying
party from any liability that it may have to any indemnified party except to the
extent  of  actual prejudice demonstrated by the indemnifying party. In case any
such  action is brought against any indemnified party, and the indemnified party
notifies  the  indemnifying  party of the commencement thereof, the indemnifying
party  will  be entitled to participate in, and, to the extent that it may wish,
jointly with any other indemnifying party similarly notified, assume the defense
thereof,  subject  to  the  provisions  herein  stated and after notice from the
indemnifying  party  to  such indemnified party of its election so to assume the
defense  thereof,  the indemnifying party will not be liable to such indemnified
party under this Section 7 for any legal or other expenses subsequently incurred
by  such  indemnified  party  in  connection with the defense thereof other than
reasonable  costs  of  investigation,  unless  the  indemnifying party shall not
pursue  the action to its final conclusion. The indemnified party shall have the
right  to  employ  separate counsel in any such action and to participate in the
defense  thereof,  but the fees and expenses of such counsel shall not be at the
expense  of  the  indemnifying  party  if the indemnifying party has assumed the
defense  of  the  action with counsel reasonably satisfactory to the indemnified
party.  No  settlement  of any action against an indemnified party shall be made
without  the prior written consent of the indemnified party, which consent shall
not  be  unreasonably  withheld.

     7.4  All  fees  and expenses of the indemnified party (including reasonable
costs  of  defense  and  investigation  in  a  manner not inconsistent with this
Section  and  all reasonable attorneys' fees and expenses), shall be paid to the
indemnified  party,  as incurred, within ten (10) days of written notice thereof
to  the  indemnifying  party;  provided, that the indemnifying party may require
such  indemnified  party to undertake to reimburse all such fees and expenses to
                                     Page 6
<PAGE>

the  extent  it  is finally judicially determined that such indemnified party is
not  entitled  to  indemnification  hereunder.

8.     CONTRIBUTION.  In  order  to  provide for just and equitable contribution
       ------------
under  the  Securities  Act or otherwise arising out of or based upon any untrue
statement  or  alleged  untrue  statement  of  any  material fact contained in a
registration statement under Section 2, or amendments or supplements thereto, or
arising  out  of  or  based  upon  the omission or the alleged omission to state
therein  a  material fact required to be stated therein or necessary to make the
statements therein not misleading in any case in which (i) the indemnified party
makes  a  claim  for  indemnification  pursuant  to  Section  7 hereof but it is
judicially  determined (by the entry of a final judgment or decree by a court of
competent jurisdiction and the expiration of time to appeal or the denial of the
last right of appeal) that such indemnification may not be enforced in such case
notwithstanding the fact that the express provisions of Section 7 hereof provide
for  indemnification in such case, or (ii) contribution under the Securities Act
or  otherwise  may  be  required on the part of any indemnified party, in either
such  case  Issuer and Permitted Right Holders shall contribute to the aggregate
losses,  claims,  damages  or  liabilities  to  which they may be subject (which
shall,  for all purposes of this Agreement, include, but are not limited to, all
reasonable  costs  of  defense  and  investigation and all reasonable attorneys'
fees),  in  either  such  case  (after contribution from others) on the bases of
relative  fault  as  well  as  any  other relevant equitable considerations. The
relative  fault shall be determined by reference to, among other things, whether
the  untrue  or  alleged  untrue statement of a material fact or the omission or
alleged  omission  to  state  a material fact relates to information supplied by
Issuer on the one hand or the Permitted Right Holders on the other hand, and the
parties'  relative  intent,  knowledge, access to information and opportunity to
correct  or  prevent such statement or omission.  Issuer and the Permitted Right
Holders agree that it would not be just or equitable if contribution pursuant to
this  Section 8 were determined by pro rata allocation or by any other method of
allocation  that  does not take account of the equitable considerations referred
to  in  this Section 8.  The amount paid or payable by an indemnified party as a
result  of  the  losses,  claims,  damages or liabilities (or actions in respect
thereof)  referred  to  above  in  this Section 8 shall be deemed to include any
legal  or  other  expenses  reasonably  incurred  by  such  indemnified party in
connection  with investigating or defending any such action or claim.  No person
guilty  of  fraudulent misrepresentation (within the meaning of Section 11(f) of
the  Securities  Act)  shall be entitled to contribution from any person who was
not  guilty  of  such  fraudulent  misrepresentation.

     This  Registration Rights Agreement ("Agreement") is entered into as of the

     WHEREAS, the Company has agreed to give the Optionee registration rights as

     NOW,  THEREFORE,  in consideration of the mutual promises, representations,

2.     PIGGYBACK  REGISTRATION  RIGHTS
       -------------------------------

       2.1     Registration Rights. If the Company at any time proposes to
               -------------------
register  its  common  stock under the Securities Act (other than on Form S-4 or
Form  S-8  promulgated  under the Securities Act or any successor forms thereto)
during the Exercise Term of the Option, the Company shall notify the Optionee in
writing  at  least  fifteen  (15)  days  prior to the filing of the registration
statement  for  purposes  of  a  public  offering  of  securities of the Company
(including,  but  not  limited to, registration statements relating to secondary
offerings  of  securities  of the Company, but excluding registration statements
relating  to employee benefit plans or with respect to corporate reorganizations
or  other transactions under Rule 145 of the Securities Act) and will afford the
Optionee  an  opportunity  to include in each such registration statement during
the  Exercise  Term of the Option, subject to the terms and conditions set forth
in  this Section 2, any of the Registrable Securities. The Company shall use its
commercially  reasonable best efforts to cause such Registrable Securities to be
included in such registration on the same terms and conditions as the securities
otherwise  being  sold  in such registration; provided, however, that if, at any
time  after  written  notice  of  its  intention  to  register  any  offering of
securities  and  prior to the effective date of the registration statement filed
in  connection  with  such  registration,  the Company determines for any reason
either  not to register or to delay registration of such securities, the Company
may,  at its election, give written notice of such determination to the Optionee
and,  thereon,  (i)  in  the  case  of  a determination not to register, will be
relieved of this obligation to register the Registrable Securities in connection
with  such  registration  (but  not  from the obligation to pay the Registration
Expenses  in  connection  therewith), and (ii) in the case of a determination to
delay  registering,  will  be  permitted  to  delay  registering the Registrable
Securities,  for  the  same  period  as  the  delay  in  registering  such other
securities.

2.2     Underwriting.  If  the  managing underwriter of an underwritten offering
        ------------
under  Section  2.1  informs the Company and the Optionee of its belief that the
inclusion  of  all  Registrable  Securities  proposed  to  be  included  in such
registration  would  interfere with the successful marketing (including pricing)
of  the  shares  proposed to be registered by the Company, then the Company will
include  in  such registration, to the extent of the number which the Company is
advised  can  be sold in the offering: first, securities proposed by the Company
                                       -----
to  be  sold  for  its own account; second, the shares of Company's common stock
                                    ------
sold  in private placements for cash during 2002, pro rata based upon the number
of  shares  of  such  securities  so  proposed to be sold and so requested to be
included;  third,  the  Registrable  Securities  requested to be included in the
           -----
registration;  and  fourth,  the  shares  of  the Company's common stock held by
                    ------
former  shareholders of HiEnergy Microdevices, pro rata based upon the number of
shares  of  such  securities  so  proposed  to  be  sold  and so requested to be
included;  provided,  however,  the  Optionee  will  have priority to all shares
sought  to  be  included  by  officers  and  directors of the Company as well as
holders  of  ten  percent  (10%)  or  more  of  the  Company's  common  stock.

3.     EXPENSES  OF  REGISTRATION.  Except  as specifically provided herein, all
       --------------------------
Registration  Expenses  incurred  in  connection  with  any  registration,
qualification  or  compliance pursuant to Section 2 herein shall be borne by the
Company.  All  Selling  Expenses  incurred  in connection with any registration,
qualification  or  compliance pursuant to Section 2 herein shall be borne by the
Optionee.

4.     REQUESTS  FOR INFORMATION. The Optionee hereby agrees to promptly furnish
       -------------------------
the  Company  with  any and all written information concerning the Optionee that
the  Company  reasonably  requests  in  order  to  (1)  prepare the registration
statements  and (2) conduct such other due diligence as may be necessary for the
Company  to satisfy or respond to any regulatory or governmental requirements or
requests.  The  Optionee  agrees  to  provide  true,  complete  and  accurate
information  based  on  a  diligent  review  of  appropriate records as would be
conducted  by a prudent man in the management of his own property.  The Optionee
understands  that  the  Company  may incorporate some or all of such information
into  the  foregoing  documents  or may determine based on such information that
certain  disclosures  are  not required, and that the Company will depend on the
Optionee  to  provide  true,  complete  and  accurate  information.

5.     TERMINATION  OF  REGISTRATION  RIGHTS.  All  registration  rights granted
under  this  Agreement,  and  all  notices  required under this Agreement, shall
terminate  and be of no further force and effect on the earlier of (i) August 1,
2004  or  (ii)  the  date that all of the shares underlying the Option have been
exercised  and  may be sold pursuant to Rule 144; provided, however, that if the
Consulting  Agreement  is  terminated  pursuant  to  Section  7.2  therein,  all
registration  rights  granted  herein  shall  immediately  terminate.

6.     INDEMNIFICATION.  In the event any Registrable Securities are included in
       ---------------
a  registration  statement  under  Section  2:

     6.1 The Company agrees to indemnify and hold harmless the Optionee and each
person  who  controls  the  Optionee  within  the  meaning of the Securities Act
against  any  losses,  claims,  damages or liabilities, joint or several, (which
shall,  for  all purposes of this Agreement, include, but not be limited to, all
reasonable  costs  of  defense  and  investigation and all reasonable attorneys'
fees),  to  which  the  Optionee  may become subject under the Securities Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect  thereof) arise out of or are based upon any untrue statement or alleged
untrue  statement  of any material fact contained in the registration statement,
or  amendments  or  supplements  thereto,  or arise out of or are based upon the
omission  or  alleged  omission  to state therein a material fact required to be
stated  therein  or  necessary  to  make  the statements therein not misleading;
provided,  however,  that the Company will not be liable in any such case to the
extent  that any such loss, claim, damage or liability arises out of or is based
upon  an  untrue  statement  or  alleged untrue statement or omission or alleged
omission  in  any  of  the  above-mentioned  documents  in reliance upon, and in
conformity  with,  written information furnished to the Company by the Optionee,
including  any  person  who  controls  the Optionee, specifically for use in the
preparation  thereof.  This  indemnity  agreement  will  be  in  addition to any
liability  that  the  Company  may  otherwise  have.

     6.2  The  Optionee  agrees  that  it  will  indemnify and hold harmless the
Company,  and  each  person  who  controls the Company within the meaning of the
Securities Act, against any losses, claims, damages or liabilities (which shall,
for  all  purposes  of  this  Agreement,  include,  but  not  be limited to, all
reasonable  costs  of  defense  and  investigation and all reasonable attorneys'
fees)  to  which  the Company or any controlling person may become subject under
the  Securities  Act  or  otherwise,  insofar as such losses, claims, damages or
liabilities  (or  actions in respect thereof) arise out of or are based upon any
untrue  statement  or alleged untrue statement of any material fact contained in
the  registration  statement, or amendments or supplements thereto, or arise out
of  or  are  based  upon the omission or the alleged omission to state therein a
material  fact required to be stated therein or necessary to make the statements

          HiEnergy Technologies, Inc. - Registration Rights Agreement
                                     Page 3

<PAGE>

therein  not  misleading,  but  in each case only to the extent that such untrue
statement  or  alleged untrue statement or omission or alleged omission was made
in  the  registration statement or amendments or supplements thereto in reliance
upon and in conformity with, written information furnished to the Company by the
Optionee  specifically  for  use  in  the  preparation  thereof.  This indemnity
agreement  will  be in addition to any liability that the Optionee may otherwise
have.

     6.3  Promptly after receipt by an indemnified party under this Section 6 of
notice  of  the  commencement  of  any action, such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under this
Section  6,  notify  the indemnifying party of the commencement thereof; but the
omission  so  to notify the indemnifying party will not relieve the indemnifying
party from any liability that it may have to any indemnified party except to the
extent  of  actual prejudice demonstrated by the indemnifying party. In case any
such  action is brought against any indemnified party, and the indemnified party
notifies  the  indemnifying  party of the commencement thereof, the indemnifying
party  will  be entitled to participate in, and, to the extent that it may wish,
jointly with any other indemnifying party similarly notified, assume the defense
thereof,  subject  to  the  provisions  herein  stated and after notice from the
indemnifying  party  to  such indemnified party of its election so to assume the
defense  thereof,  the indemnifying party will not be liable to such indemnified
party under this Section 6 for any legal or other expenses subsequently incurred
by  such  indemnified  party  in  connection with the defense thereof other than
reasonable  costs  of  investigation,  unless  the  indemnifying party shall not
pursue  the action to its final conclusion. The indemnified party shall have the
right  to  employ  separate counsel in any such action and to participate in the
defense  thereof,  but the fees and expenses of such counsel shall not be at the
expense  of  the  indemnifying  party  if the indemnifying party has assumed the
defense  of  the  action with counsel reasonably satisfactory to the indemnified
party.  No  settlement  of any action against an indemnified party shall be made
without  the prior written consent of the indemnified party, which consent shall
not  be  unreasonably  withheld.

     6.4  All  fees  and expenses of the indemnified party (including reasonable
costs  of  defense  and  investigation  in  a  manner not inconsistent with this
Section  6  and all reasonable attorney fees and expenses), shall be paid to the
indemnified  party,  as incurred, within ten (10) days of written notice thereof
to  the  indemnifying  party;  provided, that the indemnifying party may require
such  indemnified  party to undertake to reimburse all such fees and expenses to
the  extent  it  is finally judicially determined that such indemnified party is
not  entitled  to  indemnification  hereunder.

7.     CONTRIBUTION.  In  order  to  provide for just and equitable contribution
       ------------
under  the  Securities  Act or otherwise arising out of or based upon any untrue
statement  or  alleged  untrue  statement  of  any  material fact contained in a
registration statement under Section 2, or amendments or supplements thereto, or
arising  out  of  or  based  upon  the omission or the alleged omission to state
therein  a  material fact required to be stated therein or necessary to make the
statements therein not misleading in any case in which (i) the indemnified party
makes  a  claim  for  indemnification  pursuant  to  Section  6 hereof but it is
judicially  determined (by the entry of a final judgment or decree by a court of
competent jurisdiction and the expiration of time to appeal or the denial of the
last right of appeal) that such indemnification may not be enforced in such case
notwithstanding the fact that the express provisions of Section 6 hereof provide
for  indemnification in such case, or (ii) contribution under the Securities Act
or  otherwise  may  be  required on the part of any indemnified party, in either
such case the Company and the Optionee shall contribute to the aggregate losses,
claims,  damages  or  liabilities to which they may be subject (which shall, for

          HiEnergy Technologies, Inc. - Registration Rights Agreement
                                     Page 4

<PAGE>

all  purposes of this Agreement, include, but are not limited to, all reasonable
costs  of  defense  and  investigation  and  all reasonable attorneys' fees), in
either such case (after contribution from others) on the basis of relative fault
as  well  as  any  other  relevant equitable considerations.  The relative fault
shall  be  determined by reference to, among other things, whether the untrue or
alleged  untrue statement of a material fact or the omission or alleged omission
to  state  a material fact relates to information supplied by the Company on the
one  hand  or  the Optionee on the other hand, and the parties' relative intent,
knowledge,  access  to  information  and  opportunity to correct or prevent such
statement  or  omission. The Company and the Optionee agree that it would not be
just  or equitable if contribution pursuant to this Section 7 were determined by
pro  rata  allocation  or  by  any other method of allocation that does not take
account  of  the  equitable  considerations  referred to in this Section 7.  The
amount  paid  or  payable  by  an  indemnified  party as a result of the losses,
claims, damages or liabilities (or actions in respect thereof) referred to above
in  this  Section  7  shall  be  deemed  to  include any legal or other expenses
reasonably  incurred  by such indemnified party in connection with investigating
or  defending  any  such  action  or  claim.  No  person  guilty  of  fraudulent
misrepresentation  (within  the  meaning of Section 11(f) of the Securities Act)
shall  be  entitled  to  contribution from any person who was not guilty of such
fraudulent  misrepresentation.

8.     MISCELLANEOUS
       -------------

          -----------------------------
agreement among the parties concerning the subject matter of this Agreement, and
it  supersedes  any  prior  oral  or  written agreements between the parties.  A

if  expressly called for by the terms of this Agreement.  This Agreement may not

     8.4  WAIVER.  The failure of a party to insist upon strict adherence to any
          ------
term  of this Agreement on any occasion shall not be considered a waiver thereof
or deprive that party of the right thereafter to insist upon strict adherence to
that  term  or  any  other  term  of  this  Agreement.
