     This Agreement and Plan of  Reorganization  is entered into on this ___ day
of  July,  2002  ("Agreement"),   by  and  among  Cryotherm,  Inc.,  a  Delaware
corporation ("CRYO"), the undersigned  stockholders of CRYO (the "Stockholders")
and Tomahawk Industries, Inc., a Nevada corporation ("TOMAHAWK").

                                    RECITALS
                                    --------

          WHEREAS, the Stockholders own beneficially and of record all

          of the issued and outstanding shares of common stock, par

          value $.001 per share (the "CRYO Common Stock"), of CRYO;

     WHEREAS,  TOMAHAWK  desires to acquire  100% of the issued and  outstanding
CRYO Common  Stock,  making CRYO a  wholly-owned  subsidiary of TOMAHAWK and the
Stockholders  desire to make a  tax-free  exchange  of their CRYO  Common  Stock
solely  for shares of common  stock,  par value  $.001 per share (the  "TOMAHAWK
Common Stock"), of TOMAHAWK; and

     WHEREAS,  the parties intend,  by entering into this Agreement,  to adopt a
plan of reorganization within the meaning of Section 368 of the Internal Revenue
Code of 1986, as amended (the "Code").

     NOW, THEREFORE, in consideration of the covenants,  promises and agreements
set forth herein, and for other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties agree as follows:

                                    ARTICLE I
                                    AGREEMENT

     1.1 Plan of Reorganization.  CRYO, the Stockholders and TOMAHAWK agree that

shall  be  acquired  by  TOMAHAWK  in a  transaction  qualifying  as a  tax-free
stock-for-stock  exchange  pursuant  to  Section  368(a)(1)(B)  of the  Code  in
exchange solely for shares of TOMAHAWK Common Stock.

                                       1

Stock each is to  receive  will be  provided  by CRYO to  TOMAHAWK  at least two
business  days prior to the date on which the  Closing  Date.  This list of CRYO
shareholders shall be attached hereto as Exhibit "A". The Stockholders represent
and warrant to TOMAHAWK that the shares of TOMAHAWK  Common Stock that each will
receive are being acquired for investment for each Stockholder's own account and
not with a view to sale,  resale  or  distribution  except  in  compliance  with
applicable  federal and state securities laws. The Stockholders  understand that
the shares of TOMAHAWK  Common Stock they will acquire have not been  registered
under the  Securities  Act of 1933,  as  amended  (the  "Securities  Act"),  and
applicable  state  securities  law,  that they are  "restricted  securities"  as
defined under the Securities  Act and that the  certificates  representing  such
shares  of  TOMAHAWK  Common  Stock  will  bear a  legend  to such  effect.  The
Stockholders  further represent and warrant to TOMAHAWK that they are Accredited
Investors  (as defined  pursuant to the  Securities  Act) and that if any of the
Stockholders is an entity, it was not organized for the purpose of acquiring the
TOMAHAWK Common Stock. The Stockholders have had access and examined through the
Edgar program of the Securities and Exchange Commission all reports, filings and
other  documents  filed by TOMAHAWK with the Securities and Exchange  Commission
(the "SEC").

     1.3 Delivery of Shares.  At the Closing,  certificates  representing all of
the issued and  outstanding  shares of CRYO Common  Stock shall be  delivered to
TOMAHAWK,  duly endorsed for transfer or accompanied by appropriate stock powers
duly  executed.  TOMAHAWK will receive valid title to such shares of CRYO Common
Stock,  free and  clear of all liens and  other  encumbrances.  At the  Closing,
TOMAHAWK shall issue and deliver to the  Stockholders  shares of TOMAHAWK Common
Stock as provided in the list delivered to TOMAHAWK pursuant to Section 1.2.

     1.4  Capital  Structure  of  CRYO.  The  authorized  capital  stock of CRYO

TOMAHAWK  consists of  200,000,000  shares of TOMAHAWK  Common  Stock,  of which

All of the issued and outstanding TOMAHAWK Common Stock has been duly authorized
and validly issued,  and is fully paid and  nonassessable and was issued free of
preemptive rights. Except for this Agreement,  there are no outstanding options,
warrants, conversion rights, preemptive rights or other rights to subscribe for,
purchase  or  otherwise  acquire  any shares of TOMAHAWK  Common  Stock,  or any
obligation of TOMAHAWK to issue any shares of TOMAHAWK Common Stock.

                                   OF TOMAHAWK

     TOMAHAWK  represents and warrants to CRYO and the Stockholders as set forth
in this Article III:

     3.1 Organization and Qualification; Subsidiaries. TOMAHAWK was incorporated
in Nevada on May 13, 1980.  TOMAHAWK is duly incorporated,  validly existing and
in good standing under the laws of Nevada and has the requisite  corporate power
and authority to own,  lease and operate its assets and  properties and to carry
on its  business as it is now being  conducted  and as proposed to be  conducted
after  the  Closing.  TOMAHAWK  is in  possession  of  all  franchises,  grants,
authorizations,  licenses, permits, easements, consents, certificates, approvals
and orders  necessary to own,  lease and operate the  properties  it purports to
own, operate or lease and to carry on its business as it is now being conducted.
TOMAHAWK is duly qualified or licensed as a foreign  corporation to do business,
and is in good  standing,  in  each  jurisdiction  where  the  character  of the
properties owned, leased or operated by it or the nature of its activities makes
such  qualification  or  licensing  necessary.   Other  than  pursuant  to  this
Agreement,  TOMAHAWK does not directly or  indirectly  own, or have the right or
obligation  to  acquire,  any equity or  similar  interest  in, or any  interest
convertible or exchangeable or exercisable  for, any equity or similar  interest
in, any corporation,  partnership,  limited liability company,  joint venture or
other business, association or entity.

     3.2 Articles of Incorporation and Bylaws. TOMAHAWK has previously furnished
directly or through filings with the Securities and Exchange  Commission to CRYO
and  the   Stockholders   a  complete  and  correct  copy  of  its  Articles  of
Incorporation  and Bylaws as amended to date. Such Articles of Incorporation and
Bylaws are in full force and effect.  TOMAHAWK is not in violation of any of the
provisions of its Articles of Incorporation or Bylaws.

     3.3  Authority  Relative  to This  Agreement.  TOMAHAWK  has all  necessary
corporate  power and  authority  to execute and deliver  this  Agreement  and to
perform its obligations hereunder and, subject to obtaining the approval of this
Agreement  by the  holders of a majority of the  outstanding  shares of TOMAHAWK


                                       5


Common Stock, to consummate the transactions  contemplated hereby. The execution
and delivery of this Agreement by TOMAHAWK and the  consummation  by TOMAHAWK of
the transactions  contemplated  hereby have been duly and validly  authorized by
all necessary  corporate  action on the part of TOMAHAWK and no other  corporate
proceedings on the part of TOMAHAWK are necessary to authorize this Agreement or
to consummate the transactions  contemplated  hereby (other than the approval of
this  Agreement  by the  holders  of a  majority  of the  outstanding  shares of
TOMAHAWK  Common Stock).  This Agreement has been duly and validly  executed and
delivered  by  TOMAHAWK  and,  assuming  the due  authorization,  execution  and
delivery  by  CRYO  and  the  Stockholders,  constitutes  a  legal  and  binding
obligation of TOMAHAWK,  enforceable  against  TOMAHAWK in  accordance  with its
terms.

     3.4 No Conflict;  Required  Filings and  Consents.  (a) The  execution  and
delivery  of this  Agreement  by TOMAHAWK do not,  and the  performance  of this
Agreement by TOMAHAWK  shall not,  (i) conflict  with or violate its Articles of
Incorporation  or  Bylaws,  (ii)  subject  to  obtaining  the  approval  of this
Agreement  by the  holders of a majority of the  outstanding  shares of TOMAHAWK
Common  Stock,  conflict  with or  violate  any law,  rule,  regulation,  order,
judgment  or  decree  applicable  to  TOMAHAWK  or by  which  it or  any  of its
properties is bound or affected,  or (iii) result in any breach of or constitute
a default (or an event that with notice or lapse of time or both would  become a
default) under, or impair  TOMAHAWK's  rights or alter the rights or obligations
of any  third  party  under,  or give  to  others  any  rights  of  termination,
amendment,  acceleration or cancellation of, or result in the creation of a lien
or encumbrance  on any of the properties or assets of TOMAHAWK  pursuant to, any
note, bond, mortgage,  indenture,  contract,  agreement, lease, license, permit,
franchise or other  instrument or obligation to which  TOMAHAWK is a party or by
which TOMAHAWK or any of its properties is bound or affected.

     (b) The  execution  and delivery of this  Agreement by TOMAHAWK do not, and
the  performance of this  Agreement by TOMAHAWK shall not,  require any consent,
approval,  authorization  or permit of, or filing with or  notification  to, any
court,   administrative  agency,   commission,  or  governmental  or  regulatory
authority,  domestic or foreign, except for applicable requirements,  if any, of
the  Securities  Act,  the  Securities  Exchange  Act of 1934,  as amended  (the
"Exchange   Act"),   state  securities  laws,  and  the  rules  and  regulations
thereunder, and the rules and regulations of NASDAQ.


                                       6



     3.5  Compliance;  Permits.  (a)  TOMAHAWK  is not in conflict  with,  or in
default or  violation  of, (i) any law,  rule,  regulation,  order,  judgment or
decree  applicable  to  TOMAHAWK or by which any of its  properties  is bound or
affected,  or (ii) any note, bond,  mortgage,  indenture,  contract,  agreement,
lease,  license,  permit,  franchise or other  instrument or obligation to which
TOMAHAWK is a party or by which  TOMAHAWK or any of its  properties  is bound or
affected.  No  investigation or review by any governmental or regulatory body or
authority  is pending  or, to the  knowledge  of  TOMAHAWK,  threatened  against
TOMAHAWK,  nor has any governmental or regulatory body or authority indicated an
intention to conduct the same.

     (b) TOMAHAWK holds all permits, licenses, variances, exemptions, orders and
approvals from governmental  authorities which are necessary or desirable to the
operation of the business of TOMAHAWK  (collectively,  the "TOMAHAWK  Permits").
TOMAHAWK  is in  compliance  in all  respects  with the  terms  of the  TOMAHAWK
Permits.

     3.6 Financial Statements TOMAHAWK has:

     (a) Filed with the Securities and Exchange Commission financials statements
that are accurate and that are required by the Commission.

     (b) All the Financial  Statements  have been  prepared in  accordance  with
generally  accepted   accounting   principles  ("GAAP")   consistently   applied
throughout the periods  involved.  As of the date of any of such balance sheets,
except to the extent reflected therein, TOMAHAWK did not have any liabilities or
obligations  (absolute  or  contingent)  which  should be reflected in a balance
sheet or the notes  thereto  prepared in  accordance  with GAAP,  and all assets
reflected  therein are  properly  reported  and present  fairly the value of the
assets of TOMAHAWK in accordance  with GAAP.  Such  statements of operations and
comprehensive  income  present  fairly the results of operations of TOMAHAWK for
the periods  indicated.  Such statements of changes in shareholders'  equity and
cash flows present fairly the information,  which should be presented therein in
accordance  with GAAP. As of the Closing  Date,  TOMAHAWK will have no assets or
liabilities.

     (c) The  financial and other books and records of TOMAHAWK are complete and
correct and have been maintained in accordance with good business and accounting
practices,  and the Financial  Statements can be reconciled  with such books and
records.

SEC all Annual Reports on Form 10-KSB, Quarterly Reports on Form 10-QSB, Current

     (b) by  either  CRYO  or  TOMAHAWK  if the  Closing  shall  not  have  been

to terminate this Agreement  under this Section 5.1(b) shall not be available to
any  party  whose  action or  failure  to act has been a  principal  cause of or
resulted  in the failure of the Closing to occur on or before such date and such
action or failure to act constitutes a breach of this Agreement;



                                       20



     (c) by CRYO,  upon a breach of any  representation,  warranty,  covenant or
agreement on the part of TOMAHAWK;

     (d) by TOMAHAWK, upon a breach of any representation, warranty, covenant or

an order,  decree or ruling or taken any other  action,  in any case  having the
effect of  permanently  restraining,  enjoining  or  otherwise  prohibiting  the
transactions  contemplated by this  Agreement,  which order,  decree,  ruling or
other action is final and cannot be appealed.

     5.2 Notice of Termination;  Effect of Termination.  Any termination of this
Agreement pursuant t Section 5.1 will be effective immediately upon the delivery
of written notice by the terminating  party to the other parties hereto.  In the
event of any such  termination,  this Agreement  shall be of no further force or
effect, except (i) as set forth in this Section 5.2, Section 5.3 and Article VII
(General  Provisions),  each of which  shall  survive  the  termination  of this
Agreement,  and (ii) nothing  herein shall relieve any party from  liability for
any breach of this Agreement.

similar.  Any waiver must be in an instrument  in writing  signed by the waiving
party. Delay in exercising any right under this Agreement shall not constitute a
waiver of such right.

                                   ARTICLE VI

additional  action as may be reasonably  requested by any other party to confirm
or perfect title to any property transferred hereunder or otherwise to carry out
and effect the intent and purposes of this Agreement.

     7.4  Interpretation.  The table of contents and headings  contained in this
Agreement  are for  reference  purposes only and shall not affect in any way the
meaning or interpretation of this Agreement.

     7.5   Counterparts.   This  Agreement  may  be  executed  in  one  or  more
counterparts,  all of which shall be considered  one and the same  agreement and

parties need not sign the same counterpart.

     7.6 Entire  Agreement;  Third Party  Beneficiaries.  This Agreement and the
documents  and  instruments  and other  agreements  among the parties  hereto as
contemplated by or referred to herein (a) constitute the entire  agreement among
the parties with respect to the subject  matter  hereof and  supersede all prior
agreements  and  understandings,  both written and oral,  among the parties with
respect to the subject  matter  hereof;  and (b) are not intended to confer upon
any other  person  any  rights or  remedies  hereunder,  except as  specifically
provided in Section 7.11.

     7.7 Severability.  In the event that any provision of this Agreement or the
application thereof, becomes or is declared by a court of competent jurisdiction
to be illegal,  void or  unenforceable,  the  remainder of this  Agreement  will
continue in full force and effect and the application of such provision to other
persons or  circumstances  will be  interpreted  so as  reasonably to effect the
intent of the parties hereto.  The parties further agree to replace such void or
unenforceable provision of this Agreement with a valid and enforceable provision
that will achieve,  to the extent  possible,  the  economic,  business and other
purposes of such void or unenforceable provision.

     7.8 Other  Remedies;  Specific  Performance.  Except as otherwise  provided
herein,  any and all remedies  herein  expressly  conferred upon a party will be
deemed  cumulative with and not exclusive of any other remedy conferred  hereby,
or by law or equity  upon such  party,  and the  exercise  by a party of any one
remedy will not preclude the exercise of any other  remedy.  The parties  hereto
agree  that  irreparable  damage  would  occur  in  the  event  that  any of the
provisions  of this  Agreement  were not  performed  in  accordance  with  their
specific terms or were  otherwise  breached.  It is accordingly  agreed that the


                                       22


parties  shall be  entitled  to seek an  injunction  or  injunctions  to prevent
breaches of this Agreement and to enforce  specifically the terms and provisions
hereof in any court of the United States or any state having jurisdiction,  this
being in  addition to any other  remedy to which they are  entitled at law or in
equity.

     7.9  Governing  Law. This  Agreement  shall be governed by and construed in
accordance  with the laws of the State of  Nevada,  regardless  of the laws that

executed as of the date first written above.
