                            ASSET PURCHASE AGREEMENT

                  This ASSET PURCHASE  AGREEMENT is executed  December 29, 2005,
and  effective  as  of  January  1,  2006,  by  and  between   Crystalix   Group
International,  Inc.,  a  corporation  organized  under the laws of the State of
Nevada,  United States of America  ("CRYSTALIX")  and U.C. Laser Ltd., a company
organized  under the laws of the State of  Israel  of P.O.B 351  Karmiel  21613,
Israel (the "COMPANY").

                                    RECITALS

     A.    The  Company  wishes to sell to Crystalix,  and  Crystalix  wishes to
purchase  from the Company  (the  "TRANSACTION"),  all the assets of the Company
that are used in connection with the  manufacturing,  distribution and marketing
of the  Company's  decorative  images and products  (the  "COMPANY'S  BUSINESS")
including the Company's  Accounts  Receivable  (as defined  below),  the Company
Contracts (as defined below) and the Company's  worldwide,  exclusive license to
use the colored glass  technology  owned by Laser Glass Ltd. (the "COLORED GLASS
TECHNOLOGY  LICENSE") and the Company's shares in U.C. Laser, Inc. and CIC Laser
Technologies  Ltd.  (the  "PURCHASED   SUBSIDIARIES"  and,   collectively,   the
"PURCHASED ASSETS") and EXCLUDING the securities of UCLT Ltd. and of Laser Glass
Ltd. (the "EXCLUDED SUBSIDIARIES").

     B.    In  consideration of the transfer of the Purchased Assets,  Crystalix
will (i) assume the Assumed  Liabilities (as defined below),  and (ii) issue and
deliver to the Company  such number of shares of the Class B Preferred  Stock of
Crystalix (the "ISSUED Stock") as will  collectively have voting rights equal to
45% of all voting rights of Crystalix  Common Stock and any other class of Stock
as will be  outstanding  immediately  after the Closing,  determined  on a Fully
Diluted Basis (as defined  below).  The Issued Stock will be convertible  into a
total number of shares of Crystalix  Common  Stock as would,  immediately  after
such conversion,  represent 45% of all shares of capital Stock of Crystalix then
outstanding on a Fully Diluted Basis. The conversion  rights of the Issued Stock
will be exercisable  after the shareholders of Crystalix have approved a reverse
35 to 1 stock split which is  necessary  to permit  such  conversion  within the
number of shares of Common Stock  authorized in the Articles of Incorporation of
Crystalix, as referenced in Section 5.1 below.

     C.    The board of directors of each of Crystalix and the Company  believes
that it is in the best  interests of Crystalix  and the Company (as  applicable)
and  their  respective  shareholders  to  consummate  the  Transaction  and,  in
furtherance thereof, has approved the Transaction and this Agreement.

     D.    Each   of   the  Company  and  Crystalix  desires  to  make   certain
representations,  warranties,  covenants and  agreements in connection  with the
Transaction.

     NOW,   THEREFORE,   in    consideration   of   the   covenants,   premises,
representations  and warranties set forth herein,  intending to be legally bound
hereby, the parties agree as follows:

         7.2    SURVIVAL OF REPRESENTATIONS, WARRANTIES AND COVENANTS.

         Notwithstanding  any right of Crystalix or the Company  (whether or not
exercised)  to  investigate   the  affairs  of  Crystalix  or  the  Company  (as
applicable),  any information reviewed by them or any waiver by Crystalix or the
Company of any condition to Closing set forth in Article 5, all  representations
and  warranties  made  hereunder or pursuant  hereto or in  connection  with the
transactions  contemplated  hereby,  and each  party's  right to bring any claim
against the other party  pursuant to this  Agreement,  shall survive the Closing
for a period of ninety  (90) days (the  "Survival  Period").  From and after the
Survival  Period,  no party shall have any liability  whatsoever with respect to
any representation,  warranty or covenant except for: (a) breaches as to which a
party  has  notified  the  other  party  prior to such  date,  and (b)  fraud or
intentional misstatements of such party.

         7.3    INDEMNIFICATION BY THE COMPANY.

         The Company shall indemnify,  defend, and hold harmless Crystalix,  its
successors   and  assigns  and  any  entities   with  which  it  is   affiliated
(collectively,  the  "CRYSTALIX  GROUP"),  from and  against  any and all costs,
expenses,  losses,  damages,  judgments,   settlements,   fines,  penalties,  or
liabilities  (including,  without  limitation,  interest which may be imposed in
connection therewith,  court costs,  litigation expenses,  reasonable attorneys'
fees, and  accounting  fees) ("ACTUAL  LOSS")  actually  incurred or paid by the
Crystalix  Group up to the  amount of the TOTAL  INDEMNITY  AMOUNT  (as  defined
below) with respect to, in connection  with,  arising from, or alleged to result
from, arise out of, or be in connection with:

                (i)   A material breach by the Company of any  representation or
warranty made by the Company  contained in this Agreement or in any  certificate
or other document delivered by the Company to Crystalix hereunder or thereunder;

                (ii)   A  material  breach  by  the  Company  of  any  covenant,
restriction  or agreement  made by or applicable to the Company and contained in
this Agreement or in any certificate or other document  delivered by the Company
to Crystalix hereunder or thereunder;

                (iii)  Fraud or an intentional misstatement by the Company.

The Company  shall have no liability  for claims  arising under this SECTION 7.3
after the expiration of the Survival Period, except as provided in Section 7.2.

         7.4    INDEMNIFICATION OF CRYSTALIX.

         Crystalix shall indemnify, defend, and hold the Company, its successors
and assigns and any  entities  with which it is  affiliated  (collectively,  the
"COMPANY  GROUP")  harmless from and against any and all Actual Losses  actually
incurred by the  Company  Group up to the amount of the Total  Indemnity  Amount
with respect to, in  connection  with,  arising from, or alleged to result from,
arise out of, or be in connection with:

                (i)   A material  breach by Crystalix of any  representation  or
warranty made by Crystalix  contained in this Agreement or in any certificate or
other document delivered by Crystalix to the Company hereunder or thereunder;



                                      -25-
45931.0009\YOKENS\LAS\100852.3


                (ii)   A  material   breach   by  Crystalix  of  any   covenant,
restriction  or agreement  made by or  applicable  to Crystalix and contained in
this Agreement or in any certificate or other document delivered by Crystalix to
the Company hereunder or thereunder;

                (iii)  Fraud or an intentional misstatement by Crystalix.

Crystalix  shall have no  liability  for claims  arising  under this SECTION 7.4
after the expiration of the Survival Period, except as provided in Section 7.2.

         7.5    PROCEDURE FOR INDEMNIFICATION.

                (i)   The party which is entitled  to be  indemnified  hereunder
(the  "INDEMNIFIED  PARTY") shall  promptly  give notice  hereunder to the party
required to indemnify (the "INDEMNIFYING  PARTY") after obtaining written notice
of any Action or  Proceeding  as to which  recovery  may be sought  against  the
Indemnifying  Party  because of the  indemnity  in SECTION  7.3 and  SECTION 7.4
hereof and, if such indemnity shall arise from the claim of a third party, shall
permit  the  Indemnifying  Party to  assume  the  defense  of any  such  Action.
Notwithstanding the foregoing, the right to indemnification  hereunder shall not
be affected by any failure of an Indemnified Party to give such notice, or delay
by an  Indemnified  Party in giving  such  notice  unless,  and then only to the
extent that, the rights and remedies of the  Indemnifying  Party shall have been
prejudiced as a result of the failure to give, or delay in giving,  such notice.
Failure by an Indemnifying  Party to notify an Indemnified Party of its election
to defend any such Action by a third party within  thirty (30) days after notice
thereof shall have been given to the Indemnifying Party shall be deemed a waiver
by the Indemnifying Party of its right to defend such Action.

                (ii)   If the  Indemnifying  Party  assumes  the defense of such
Action,  the obligations of the  Indemnifying  Party hereunder as to such Action
shall  include  taking all steps  necessary in the defense or settlement of such
Action and holding the  Indemnified  Party harmless from and against any and all
damages caused by or arising out of any settlement  approved by the Indemnifying
Party or any judgment in connection  with such Action.  The  Indemnifying  Party
shall not,  in the  defense  of such  Action,  consent to entry of any  judgment
(other than a judgment of dismissal on the merits without costs) except with the
written consent of the Indemnified  Party, or enter into any settlement  (except
with the written consent of the Indemnified  Party) which does not include as an
unconditional  term thereof the giving by the  claimant or the  plaintiff to the
Indemnified  Party a release  from all  liability  in respect of such Action and
which does not have an adverse affect on the assets,  business or otherwise,  or
operations  of the  Indemnified  Party.  Anything  in  this  SECTION  7.5 to the
contrary notwithstanding,  the Indemnified Party may, with counsel of its choice
and at its expense, participate in the defense of any such Action. In all cases,
the Indemnified Party shall cooperate with the Indemnifying Party in the defense
of any Action,  including by making  employees,  information,  and documentation
reasonably available at reasonable times.

                (iii)  If  the Indemnifying Party does not assume the defense of
any such  Action  after  receipt  of notice  from such  Indemnified  Party,  the
Indemnified  Party may defend  against  such  Action in such  manner as it deems
appropriate  and,  unless  the   Indemnifying   Party  shall  deposit  with  the
Indemnified  Party a sum equivalent to the total amount  demanded in such




                                      -26-
45931.0009\YOKENS\LAS\100852.3



Action plus the Indemnified Party's estimate of the costs of defending the same,
the Indemnified  Party may settle such Action on such terms as it may reasonably
deem appropriate.

                (iv)   The  Indemnifying  Party  shall  promptly  reimburse  the
Indemnified Party for the amount of all Actual Losses of the Indemnified  Party,
whether or not resulting from,  arising out of, or incurred with respect to, the
act of a third  party.  If the  Indemnifying  Party is the  Company,  the Actual
Losses of Crystalix  shall be satisfied  solely by a release of shares of Issued
Stock from the Indemnity Escrow Account to Crystalix,  with each share of Issued
Stock in the Indemnity Escrow Account to be valued at a per share price equal to
the average  closing  price of  publicly  traded  shares over the 90-day  period
preceding the date of valuation,  for purposes of reimbursing  Crystalix for any
Actual Losses (the "TOTAL  INDEMNITY  AMOUNT");  The Company shall not be liable
for any amount which exceeds the TOTAL INDEMNITY  AMOUNT;  PROVIDED HOWEVER that
in the event the Actual Losses are caused by fraud of the Company and the shares
of Issued Stock in the Indemnity  Escrow Account are  insufficient  to reimburse
Crystalix in full for such Actual Losses,  the Company shall promptly  deliver a
cash payment to Crystalix in the amount of Actual Losses for which Crystalix was
not  reimbursed  through the release of shares of Issued Stock in the  Indemnity
Escrow Account.

consummation  of the  Transaction;  or (ii) there  shall be any  statute,  rule,
regulation or order enacted,  promulgated or issued or deemed  applicable to the
Transaction  by  any  Governmental  or  Regulatory  Authority  that  would  make
consummation of the Transaction illegal;

                      (c)  by Crystalix  if it is  not  in  material  breach  of
its representations,  warranties,  covenants and agreements under this Agreement
and  there  has been a  breach  of any  representation,  warranty,  covenant  or
agreement contained in this Agreement on the part of the Company and the Company
is not using its reasonable  efforts to cure such breach,  or has not cured such
breach within thirty days, after notice of such breach to the Company (PROVIDED,
HOWEVER, that, no cure period shall be required for a breach which by its nature
cannot be cured);

                      (d)  by the Company  if it is not in  material  breach  of
its representations,  warranties,  covenants and agreements under this Agreement
and  there  has been a  breach  of any  representation,  warranty,  covenant  or
agreement  contained in this Agreement on the part of Crystalix and Crystalix is
not using its  reasonable  efforts  to cure such  breach,  or has not cured such
breach within thirty days,  after notice of such breach to Crystalix  (PROVIDED,
HOWEVER,  that no cure period shall be required for a breach which by its nature

                      (f)  as provided in Section 6.4 and Section 6.5.

         8.2    EFFECT OF TERMINATION.

         In the event of a valid  termination  of this  Agreement as provided in
Section 8.1, this Agreement  shall  forthwith  become void and there shall be no
liability  or  obligation  on the part of  Crystalix  or the  Company,  or their
respective  officers,  directors or  shareholders  or Affiliates or  Associates;
PROVIDED,  HOWEVER, that each party shall remain liable for any breaches of this
Agreement prior to its termination; and provided further that, the provisions of
Section 5.4,  this  Section 8.2 and of Article 9 (exclusive  of Section 9.3) and
the  applicable  definitions  set forth in Article 10 shall remain in full force
and effect and survive any termination of this Agreement.

         8.3    EXTENSION; WAIVER.

extent legally  allowed,  (a) extend the time for the  performance of any of the
obligations  of the  other  party  hereto,  (b) waive  any  inaccuracies  in the
representations  and warranties  made to such party  contained  herein or in any
document  delivered  pursuant  hereto,  and (c) waive compliance with any of the
agreements,  covenants  or  conditions  for the benefit of such party  contained
herein.  Any  agreement on the part of a party  hereto to any such  extension or
waiver shall be valid only if set forth in an  instrument  in writing  signed on
behalf of such party.

         9.2    ENTIRE AGREEMENT.

         This  Agreement  and the Exhibits and Schedules  hereto,  including the
Company Disclosure Schedule and the Crystalix  Disclosure  Schedule,  constitute

under this Agreement and the Transaction  contemplated hereby. Each party agrees
to  use  commercially   reasonable  efforts  to  cause  the  conditions  to  its
obligations to consummate the Transaction to be satisfied.

         9.4    WAIVER.

         Any term or  condition of this  Agreement  may be waived at any time by

effective unless set forth in a written instrument duly executed by or on behalf
of the party waiving such term or condition.  No waiver by any party of any term

         The terms and provisions of this Agreement are intended  solely for the

successors and assigns.

         9.8    INVALID PROVISIONS.

         If any  provision of this  Agreement is held to be illegal,  invalid or
unenforceable  under any present or future Law, and if the rights or obligations
of any party hereto under this  Agreement  will not be materially  and adversely
affected thereby, (a) such provision will be fully severable, (b) this Agreement
will be construed  and  enforced as if such  illegal,  invalid or  unenforceable
provision had never  comprised a part hereof,  (c) the  remaining  provisions of
this  Agreement will remain in full force and effect and will not be affected by
the illegal, invalid or unenforceable provision or by its severance herefrom and
(d) in lieu of such illegal, invalid or unenforceable  provision,  there will be
added  automatically as a part of this Agreement a legal,  valid and enforceable
provision  as  similar  in  terms  to such  illegal,  invalid  or  unenforceable
provision as may be possible.

         9.9    GOVERNING LAW.

         This  Agreement,  the schedules  attached  hereto and any other Closing
documents  shall be governed by and construed in accordance with the laws of the
State of Israel,  without  giving effect to any choice of law or conflict of law
provision  or rule  (whether  of the State of Israel or any other  jurisdiction)
that would cause the application of the laws of any jurisdiction  other than the
State of Israel;  provided,  however, that any matter pertaining to the validity
of the Issued Shares,  Shareholder Agreement and Company Proxy shall be governed
by the laws of the State of Nevada. The competent courts within Tel Aviv, Israel
shall have exclusive  jurisdiction to adjudicate any dispute arising out of this
Agreement;  provided, however, that any matter pertaining to the validity of the
Issued  Shares,  Shareholder  Agreement  and  Company  Proxy shall be within the
jurisdiction  of U.S.  federal and state  courts  located in Las Vegas,  Nevada,
U.S.A.

         9.10   .CONSTRUCTION.

         The  parties  hereto  agree  that  this  Agreement  is the  product  of
negotiations  between  sophisticated  parties and individuals,  all of whom were
represented  by counsel,  and each of whom had an  opportunity to participate in
and did  participate  in, the drafting of each  provision  hereof.  Accordingly,
ambiguities in this  Agreement,  if any,  shall not be construed  strictly or in
favor of or  against  any  party  hereto  but  rather  shall be given a fair and
reasonable construction.

         9.11   COUNTERPARTS.

         This Agreement may be executed in any number of  counterparts,  each of
which will be deemed an original,  but all of which together will constitute one
and the same instrument.

         9.12   SPECIFIC PERFORMANCE.

         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 agreed
that the parties shall be entitled to an injunction  or  injunctions  to prevent
breaches of this Agreement and to enforce  specifically the terms and provisions
hereof in any court provided in Section 9.9 above, this being in addition to any
other remedy to which they are entitled at law or in equity.
