Closing does not occur within a reasonable  time following July 3, 2000,  unless
such  failure to close (i) is caused by Seller,  or (ii) arises  from  Gentner's
discovery  during due  diligence of any lien,  encumbrance,  security  interest,
claim, license, grant, infringement of Seller's Intellectual Property rights, or
Seller's  infringement of the  Intellectual  Property rights of any third party,

the  Deposit  when  required  to do so by this  Section,  the  Deposit  shall be

the Applicable  Rate,  and Seller shall execute such loan  documents  reasonably
required by Buyer to perfect its  security  interest  in Seller's  assets.

the  Indemnified  Party need not consult with,  or obtain any consent from,  any
Indemnifying Party in connection  therewith),  and (B) the Indemnifying  Parties
will remain  responsible for any Adverse  Consequences the Indemnified Party may
suffer resulting from,  arising out of, relating to, in the nature of, or caused
by the Third Party Claim to the fullest extent provided in this Section 8.

         8.1.5  Determination  of Adverse  Consequences.  The Parties shall take
into account the time cost of money (using the  Applicable  Rate as the discount


                                                                            E-25


rate) in determining  Adverse  Consequences  for purposes of this Section 8. All
indemnification payments under this Section 8 shall be deemed adjustments to the
Purchase Price.

         8.1.6  Certain  Set-Off  Rights.  The Escrowed  Shares and the Escrowed
Amount shall be placed in escrow at Closing  pursuant to Section 2(c) above, for
the Escrow Period  commencing  on the Closing  Date,  with an Escrow Agent to be
agreed upon by the Parties (the "Escrow Agent"). The Parties shall enter into an
escrow agreement (the "Escrow Agreement") with the Escrow Agent containing terms
consistent  with the  provisions  of this  Agreement.  The Buyer  shall have the
option of recouping  all or any part of any Adverse  Consequences  it may suffer
(in lieu of  seeking  any  indemnification  to which it is  entitled  under this
Section 8) by notifying the Seller in writing of such Adverse  Consequences (the
"Set-Off Claim") stating (i) the amount of such Adverse  Consequences,  and (ii)
the basis for such claim of  Adverse  Consequences  in  sufficient  details  for
Seller  to  evaluate  the  Set-Off  Claim;  Seller  shall  have ten (10) days to
evaluate  and respond to Buyer's  Set-Off  Claim in writing.  If Seller does not
dispute  Buyer's  Set-Off  Claim,  Buyer shall be entitled to set off such claim
against the Escrowed Amount,  and thereafter against the Escrowed Shares. In the
event that the Seller  disputes a Set-Off  Claim,  the parties will resolve such
dispute using the procedure described in Section 10(p) below,  provided that, if
the Escrow Period  described in this section  expires  during the existence of a
dispute involving a Set-Off Claim, the Escrow Agent shall retain an amount equal
to the Set-Off  Claim in escrow  pending  resolution  of the  dispute,  and will
release the balance of the Escrowed Amount and Escrowed Shares to Seller.

         8.1.7 Notwithstanding  anything to the contrary in this Agreement,  the
Seller  shall have no  obligation  to  indemnity  the Buyer from and against any
Adverse  Consequences  unless  and until  the  aggregate  indemnifiable  Adverse
Consequences  suffered by the Buyer equal or exceed $34,000, net of any proceeds
actually  received from any insurance  policy or policies  covering such Adverse
Consequences  (the  "Basket"),  at which point the Seller  shall be obligated to
indemnify the Buyer for all Adverse  Consequences  (including the Basket). In no
event shall the Seller's  liability  to indemnity  the Buyer exceed the Purchase
Price.

         8.1.8 The foregoing indemnification provisions in this Section 8 are in
addition to, and not in derogation of, any statutory,  equitable,  or common law
remedy   (including   without   limitation   any  such  remedy   arising   under
Environmental,  Health, and Safety Requirements) any Party may have with respect
to the transactions contemplated by this Agreement.

                       ARTICLE 9 -- Additional Covenants.
                       ----------------------------------

         9.1.1  Confidentiality.  Except  as set  forth  in press  releases  and
announcements  approved in advance by each of the  Parties,  the  existence  and
terms of this  Agreement are strictly  confidential  and may not be disclosed to
anyone  other than to the  directors,  officers  and advisers of the Parties who
have fiduciary or legal responsibilities to keep such information  confidential.
Seller shall use its best efforts to prevent its officers, directors,  employees
and  shareholders  from trading in Buyer's stock pending public  announcement by
the Parties of the  Agreement.  Each Party  agrees that it will not  disclose to
third parties  information deemed confidential by the other Party, other than as
required by applicable law.


                                                                            E-26


         9.1.2  Non-Compete.  Seller  agrees  that,  for a period of three years
following  the  Closing,  it will not  develop,  license or sell any products or
services  within or  without  the U.S.  that are  competitive  with the lines of
business of Gentner that utilize any of the Acquired Assets.

         9.1.3 Share Certificate  Legends. The Seller understand and agrees that
each certificate  representing  Gentner Shares received hereunder shall bear the
following legends:

                  "THE   TRANSFER  OF  THE   SECURITIES   REPRESENTED   BY  THIS
                  CERTIFICATE  IS RESTRICTED BY AN ASSET  PURCHASE  AGREEMENT ON
                  FILE AT THE OFFICES OF THE CORPORATION."

                  "THE SECURITIES  REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
                  REGISTERED  UNDER THE SECURITIES ACT OF 1933 OR THE SECURITIES
                  LAWS OF ANY STATE AND MAY NOT BE SOLD OR OTHERWISE DISPOSED OF
                  EXCEPT PURSUANT TO AN EFFECTIVE  REGISTRATION  STATEMENT UNDER
                  SUCH ACT AND APPLICABLE STATE SECURITIES LAWS OR AN APPLICABLE
                  EXEMPTION TO THE REGISTRATION REQUIREMENTS OF SUCH ACT OR SUCH
                  LAWS."

                          ARTICLE 10 -- Miscellaneous.
                          ----------------------------

         10.1.1  Term  Sheet.  The  Parties   acknowledge  that  this  Agreement
supersedes  that certain term sheet executed by Buyer,  Seller and the Principal
Shareholders dated effective April 18, 2000.

         10.1.2 Press  Releases and Public  Announcements.  Other than the press
release  issued  jointly by the Parties on or about May 19, 2000, no Party shall
issue any press release or make any public announcement  relating to the subject
matter of this Agreement prior to the Closing without the prior written approval
of the other  Party;  provided,  however,  that any  Party  may make any  public
disclosure  it  believes  in good faith is  required  by  applicable  law or any
listing or trading agreement concerning its publicly-traded securities (in which
case the  disclosing  Party will use its  reasonable  best efforts to advise the
other Party prior to making the disclosure).  The Seller  acknowledges  that the
Buyer will file a Form 8-K with the U.S.  Securities and Exchange  Commission in
connection with the transactions contemplated hereby.

         10.1.3 No Third-Party  Beneficiaries.  This Agreement  shall not confer

respective successors and permitted assigns.

         10.1.4  Entire  Agreement.  This  Agreement  (including  the  documents
referred to herein)  constitutes  the entire  agreement  between the Parties and
supersedes  any  prior  understandings,  agreements,  or  representations  by or
between the Parties,  written or oral,  to the extent they related in any way to
the subject matter hereof.


                                                                            E-27

any  or all of  its  rights  and  interests  hereunder  to  one or  more  of its
Affiliates  and (ii)  designate  one or more of its  Affiliates  to perform  its
obligations  hereunder (in any or all of which cases the Buyer nonetheless shall
remain responsible for the performance of all of its obligations hereunder).

         10.1.6  Counterparts.  This  Agreement  may be  executed in one or more
counterparts,  each of  which  shall  be  deemed  an  original  but all of which
together will constitute one and the same instrument.

         10.1.7 Headings.  The section headings  contained in this Agreement are
inserted  for  convenience  only and shall not affect in any way the  meaning or

communication hereunder to the intended recipient at the address set forth above
using any other means (including personal delivery, expedited courier, messenger
service,  telecopy,  telex,  ordinary  mail,  or electronic  mail),  but no such
notice,  request,  demand, claim, or other communication shall be deemed to have
been duly  given  unless  and until it  actually  is  received  by the  intended
recipient. Any Party may change the address to which notices, requests, demands,
claims,  and other  communications  hereunder  are to be delivered by giving the
other Party notice in the manner herein set forth.

         10.1.9 Governing Law. This Agreement shall be governed by and construed
in  accordance  with the laws of the State of Utah without  giving effect to any
choice or conflict of law provision or rule that would cause the  application of
the laws of any jurisdiction other than the State of Utah.

         10.1.10  Amendments and Waivers.  No amendment of any provision of this
Agreement  shall be valid  unless the same shall be in writing and signed by the
Buyer and the Seller.  The Seller may consent to any such  amendment at any time
prior to the Closing  with the prior  authorization  of its board of  directors;
provided,  however,  that any amendment  effected after the Seller  Shareholders
have approved this  Agreement will be subject to the  restrictions  contained in
applicable law concerning such approval.  No waiver by any Party of any default,
misrepresentation,   or  breach  of  warranty  or  covenant  hereunder,  whether
intentional  or not,  shall be  deemed  to  extend  to any  prior or  subsequent
default,  misrepresentation,  or breach of  warranty or  covenant  hereunder  or
affect in any way any rights  arising by virtue of any prior or subsequent  such
occurrence.

         10.1.11  Severability.  Any term or provision of this Agreement that is
invalid or unenforceable  in any situation in any jurisdiction  shall not affect

situation or in any other jurisdiction.

costs and expenses  (including  legal fees and expenses)  incurred in connection
with this Agreement and the transactions contemplated hereby.

         10.1.13  Construction.  The Parties  have  participated  jointly in the
negotiation  and  drafting  of this  Agreement.  In the  event an  ambiguity  or
question of intent or interpretation  arises,  this Agreement shall be construed
as if drafted jointly by the Parties and no presumption or burden of proof shall
arise  favoring or  disfavoring  any Party by virtue of the authorship of any of
the provisions of this Agreement. Any reference to any federal, state, local, or
foreign  statute  or law  shall  be  deemed  also  to  refer  to all  rules  and
regulations promulgated thereunder,  unless the context requires otherwise.  The
word  "including"  shall mean including  without  limitation.  At the request of
Buyer, Seller has disclosed each exception to a representation and warranty with


                                                                            E-29


reasonable  particularity and described the relevant facts in reasonable detail.
The Parties intend that each  representation,  warranty,  and covenant contained
herein  shall  have  independent  significance.  If any Party has  breached  any
representation,  warranty, or covenant contained herein in any respect, the fact
that there exists another representation,  warranty, or covenant relating to the
same subject matter (regardless of the relative levels of specificity) which the
Party has not  breached  shall not detract  from or  mitigate  the fact that the
Party is in breach of the first representation, warranty, or covenant.

         10.1.14  Incorporation  of Exhibits  and  Schedules.  The  Exhibits and
Schedules  identified in this Agreement are incorporated herein by reference and
made a part hereof.

         10.1.15  Specific  Performance.  Each of the Parties  acknowledges  and
agrees that the other Party would be damaged irreparably in the event any of the
provisions of this Agreement are not performed in accordance with their specific
terms or otherwise are breached.  Accordingly,  each of the Parties  agrees that
the other Party shall be entitled to an  injunction  or  injunctions  to prevent
breaches of the  provisions of this Agreement and to enforce  specifically  this
Agreement and the terms and  provisions  hereof in any action  instituted in any
court of the United States or any state  thereof  having  jurisdiction  over the
Parties  and the  matter,  in  addition  to any other  remedy to which it may be
entitled, at law or in equity.

         10.1.16 Dispute Resolution.  Subject to the provisions of Section 10(o)
above,  any  dispute  arising  out  of or in  connection  with  this  Agreement,
including any question regarding its existence,  validity or termination,  shall
be settled: first, by good faith negotiation between the Parties for a period of
no more than ten (10) days following  written  notice by the disputing  Party to
the other Party of such dispute;  then, if unresolved,  by non-binding mediation
for a period of thirty (30) days before a mutually  satisfactory  mediator.  Any
dispute  remaining  unresolved  following  mediation shall be settled by binding
arbitration  before  a  single  arbitrator  under  the  Rules  of  the  American
Arbitration  Association  for  Commercial  Disputes (the "Rules" (as modified by
this  section)).   Judgment  upon  the  award  rendered  by  the  arbitrator  or
arbitrators may be entered in any court having jurisdiction  thereof,  and shall
be binding on the Parties hereto. The costs of arbitration, including reasonable
legal  fees  and  costs,  shall be borne by  either  or both of the  Parties  in
whatever proportion as the arbitrator or arbitrators may award.

         10.1.17  Employee  Benefits  Matters.  The Buyer may,  but shall not be
obligated,  to hire  certain  Employees  of Seller.  In any event,  Seller shall
remain  responsible  for each of the  Employee  Benefit  Plans  that the  Seller
maintains following the Closing (and for terminating such Employee Benefit Plans
that  Seller  elects not to  maintain  following  the  Closing)  and each trust,
insurance  contract,  annuity  contract,  or other funding  arrangement that the
Seller  has  established  with  respect  thereto,  and  Buyer  shall  assume  no
responsibility or obligation therefor.

         IN WITNESS WHEREOF,  the Parties hereto have executed this Agreement as
of the date first written above.

                         AMENDMENT TO LICENSE AGREEMENT

     THIS AMENDMENT TO LICENSE AGREEMTNT (the "Amendment") is entered into as of
the 1st day of June,  2000 by and among Gentner  Communications  Corporation,  a
Utah  corporation  ("Assignee" or "Gentner"),  ClearOne,  Inc., a  Massachusetts
corporation  ("Licensor" or "ClearOne") and Ezenia, Inc., a Delaware corporation
(formerly VideoServer,  Inc.) ("Licensee" or "Ezenia"),  the foregoing sometimes
referred to collectively herein as the "parties."

                             ARTICLE 11 -- RECITALS
                             ----------------------


                           A.  ClearOne and  Licensee  entered into that certain
                  License   Agreement   dated  March  24,  1999  (the   "License
                  Agreement"),  relating  to the  license of certain  technology
                  owned by ClearOne.

                           B.   Gentner   and   ClearOne   have   entered   into
                  negotiations   concerning  a  proposed  transaction  in  which
                  Gentner contemplates acquiring certain assets of ClearOne (the
                  "Acquired  Assets").  The Acquired Assets include software and
                  other  intellectual  property of  ClearOne,  some of which has
                  been licensed to Licensee pursuant to the License Agreement.

                           C.  Subject to the closing of  Gentner's  purchase of
                  the  Acquired  Assets,  the parties  wish to amend the License
                  Agreement as set forth herein.

         NOW,  THEREFORE,  for  good and  valuable  consideration,  the  parties
mutually covenant and agree as follows:

1. Capitalized Terms. Except as otherwise defined herein, capitalized terms used
in this  Amendment  shall have the  meanings  given to such terms in the License
Agreement.

2. Deletion of Provisions.  The texts of Section 1.5, Section 2, and Section 6.2
of the License Agreement are hereby deleted in their entirety,  and the notation
"Intentionally  Omitted" shall be inserted in place of each deleted provision to
maintain existing numbering of the Sections.

3. Gentner as Assignee. Gentner hereby agrees to be bound by all of the terms of
the License  Agreement  and to assume all of ClearOne's  rights and  obligations
thereunder as modified and amended by this Amendment.


                                                                            E-33


4.  Deliverables;  License Fees.  Licensee hereby  acknowledges  that it has (i)
accepted all of the Deliverables,  (ii) received or waived the training to which
it was entitled pursuant to Section 5 of the License Agreement,  and (iii) shall
not be  entitled  to  receive,  and  Gentner  shall not be  required  to deliver
additional  Hardware Units under the License  Agreement.  The parties each agree
that Licensee shall not be obligated to pay additional  License Fees pursuant to
Section 6.1 of the License Agreement.

5.  Condition to  Effectiveness.  This  Amendment  shall not be binding upon the
parties  or modify  the  License  Agreement  unless  and until  the  closing  of
Gentner's   purchase  of  the  Acquired   Assets  pursuant  to  the  transaction
contemplated between Gentner and ClearOne.

6.  Affirmation of the Lease.  Gentner and Licensee hereby affirm and ratify the
License  Agreement,  and agree that the License  Agreement,  as amended  hereby,
shall remain in full force and effect.


         IN WITNESS  WHEREOF,  the parties have caused this Amendment to be duly
         executed as of the date of the first above written.

     This Registration  Rights Agreement (the "Agreement") is entered into as of
July  5,  2000,  by  and  between  Gentner  Communications  Corporation,  a Utah

("Purchaser" or "Purchasers").

1.       Definitions.  As used in this Agreement, the following terms shall have

         "Holder" or "Holders"  shall mean any  Purchaser or any assignee  under
this Agreement who holds any Registrable Securities (as defined below).

         The  terms  "register,"  "registered"  and  "registration"  refer  to a

Purchasers which have not been registered pursuant to this Agreement.

         "Registration Expenses" shall mean all expenses incurred by the Company
in connection with a registration hereunder,  including, without limitation, all

stock dividend, recapitalization, or similar event applicable to such Shares.

2.       "Piggy-Back" Registration.
         -------------------------

         (a) If the Company  shall  determine at any time to register any of its
Common Stock or securities  which are convertible into or exercisable for Common
Stock (other than a registration  relating  solely to employee  benefit plans, a
registration  relating solely to an SEC Rule 145 transaction,  a registration on
Form S-4,  or a  registration  on any  registration  form  which does not permit
secondary sales or does not include  substantially the same information as would
be  required to be included in a  registration  statement  covering  the sale of
Registrable  Securities),  the Company  will:  (i) promptly  give to the Holders
written notice thereof (which shall include a list of the jurisdictions in which
the Company intends to attempt to qualify such  securities  under the applicable
blue sky or other state securities  laws), and (ii) cause to be included in such
registration  and in any  underwriting  involved  therein  all  the  Registrable
Securities specified in a written request or requests made by the Holders within
ten (10) days after receipt of such written  notice from the Company;  provided,
however, that the number of Registrable  Securities so registered may be limited
by the underwriter's cut-back provision set forth in Subsection 2(c) below.

         (b) If the  registration  of which the  Company  gives  notice is for a
registered  public  offering  involving an  underwriting,  the Company  shall so
advise the Holders as part of the written  notice given  pursuant to  Subsection
2(a). In such event, the right of each Holder to register  pursuant to Section 2
shall be conditioned upon such Holder's  participation in such  underwriting and
the inclusion of such Holder's Registrable Securities in the underwriting to the
extent provided herein.

         (c) Any Holders  proposing to distribute their  Registrable  Securities
through  such  underwriting  shall  (together  with the  Company)  enter into an
underwriting  agreement  in  customary  form  with  the  representative  of  the
underwriter  or   underwriters   selected  for   underwriting  by  the  Company.
Notwithstanding  any other provision of this Section 2, the Company shall not be
required to include in the registration the Registrable Securities of any Holder
unless the Holder accepts and agrees to the terms  proposed by the  underwriters
selected  by the  Company,  and then only in such  quantity  as will not, in the
opinion of the  underwriters and based on marketing  factors  identified by such
underwriters,  jeopardize  the success of the  offering by the  Company.  If the
total number of Registrable  Securities which the Holders request to be included
in any offering exceeds the number of Shares which the  underwriters  reasonably
believe  is  compatible  with the  success of the  offering,  then the number of
shares to be registered  shall be reduced as between the Holders and the Company
pro rata based on the ratio of (i) the  Registrable  Shares to be  registered to
(ii) all shares of Common Stock of the Company to be  registered,  provided that
the number of shares of  Registrable  Securities  of the  Holders to be included
shall not be reduced by more than fifty  percent  (50%) of the total shares that
the Holders have requested be included in the registration.

                                                                            E-39



3.       Obligations of the Company. Whenever required under Section 2 to effect
the  registration  of any  Registrable  Securities,  the  Company  shall  do the
following as expeditiously as possible:

         (a) Prepare and file with the SEC a registration statement with respect
to such Registrable Securities and use its reasonable best efforts to cause such
registration statement to become and remain effective;  provided, however, that,
except as set forth in Subsection  3(b) below,  the Company shall in no event be
obligated to cause such registration statement to remain effective for more than
one hundred twenty (120) days.

         (b) If the  registration  is  effected  pursuant  to Rule 415 under the
Securities  Act,  which rule allows for the  registration  of  securities  to be
offered on a continuous or delayed  basis,  the Company shall  promptly (i) take
all actions that may be necessary or advisable to maintain the  effectiveness of
such registration,  (ii) at Purchaser's request,  file with the SEC a supplement
or supplements to the previously  filed prospectus as required by Rule 424 under
the Securities Act, and (iii) maintain the  effectiveness  of such  registration
statement for at least one hundred twenty (120) days following the filing of any
such supplements.

         (c) Prepare and file with the SEC such  amendments  and  supplements to
such registration  statements and the prospectus used in connection therewith to
comply with the requirements of the Securities Act.

         (d)  Furnish  to the  Holders  such  number of  copies of a  prospectus
(including a preliminary prospectus), in conformity with the requirements of the
Securities Act, and such other documents as such Holders may reasonably  request
in order to facilitate the disposition of the Registrable  Securities to be sold
under the registration statement.

         (e) Use its  reasonable  best  efforts  to  register  and  qualify  the
securities covered by such registration  statements under the securities laws of
such  states of the United  States as shall be  reasonably  appropriate  for the
distribution of the securities covered by such registration statement.

4.       Information  by  Holder.  It  shall  be  a condition  precedent  to the
obligations  of the Company to take any action  pursuant to this  Agreement that
the  Holders  of  Registrable  Securities  included  in any  registration  shall
cooperate  with the Company and any  underwriters  to effect such  registration,
including  providing to the Company any consents and  furnishing  to the Company
such information  regarding such Holders and the  distribution  proposed by such
Holders  as the  Company  may  reasonably  request  in  writing  and as shall be
required in  connection  with any  registration,  qualification,  or  compliance
referred to in this Agreement.

5.       Expenses  of  Registration.   All   Registration  Expenses  incurred in
connection  with any  registration,  qualification,  or  compliance  pursuant to
Section  2 of this  Agreement  shall be borne by the  Company,  and all  Selling
Expenses  shall be borne by the Holders of the securities so registered pro rata
on the basis of the number of their Shares so registered.


                                                                            E-40


6.       No  Delay  of Registration.  No Holder shall have any right to take any
action to restrain,  enjoin,  or  otherwise  delay any  registration  under this
Agreement  as a result of any  controversy  that might arise with respect to the
interpretation or implementation hereof.

7.       Indemnification.  In  the  event  that  the Registrable Securities of a
Holder are included in a registration statement filed under this Agreement:

         (a) To the extent  permitted by law, the Company  will  indemnify  each
such Holder,  each of its  officers,  directors  and  partners,  and each person
controlling such Holder, with respect to which registration,  qualification,  or
compliance of Registrable  Securities of such Holder has been effected  pursuant
to this Agreement,  and each  underwriter,  if any, and each person who controls
any underwriter, against all claims, losses, damages and liabilities (or actions
in  respect  thereof)  arising  out of or based  on any  untrue  statement  of a
material fact  contained in any  registration  statement,  prospectus,  offering
circular or other document incident to any such registration,  qualification, or
compliance,  or based on any omission to state  therein a material fact required
to be stated therein or necessary to make the statements therein not misleading,
or any  violation  by  the  Company  of the  Securities  Act or of any  rule  or
regulation  promulgated  under the  Securities Act applicable to the Company and
relating to action or inaction  required of the Company in  connection  with any
such registration,  qualification,  or compliance,  and will reimburse each such
Holder,  each of its officers,  directors and partners,  each person controlling
such  Holder,  each such  underwriter,  and each  person who  controls  any such
underwriter,  for any legal and other expenses reasonably incurred in connection
with  investigating and defending any such claim, loss,  damage,  liability,  or
action;  provided  that the  Company  will not be  liable  in any such  case for
amounts paid in settlement of any such claim, loss, damage, liability, or action
if such  settlement is effected  without the  reasonable  consent of the Company
(which  consent shall not be  unreasonably  withheld),  nor shall the Company be
liable to the extent that any such claim,  loss, damage,  liability,  or expense
arises  out of or is  based on any  untrue  statement  or  omission  in  written
information  furnished to the Company by such Holder with the knowledge  that it
would be used in the registration statement.

         (b) To the extent  permitted by law, each Holder will,  if  Registrable
Securities  held by such  Holder  are  included  in the  securities  as to which
registration,  qualification  or  compliance  is being  effected,  indemnify the
Company, each of its directors and officers,  each legal counsel and independent
accountant of the Company, each underwriter, if any, of the Company's securities
covered by such a registration  statement,  each person who controls the Company
or such  underwriter  within the meaning of the  Securities  Act, and each other
Holder, each of such other Holder's officers,  directors, and partners, and each
person controlling such other Holder, against all claims,  losses,  damages, and
liabilities  (or  actions in  respect  thereof)  arising  out of or based on any
untrue  statement (or alleged untrue  statement) of a material fact contained in
any  such  registration  statement,  prospectus,  offering  circular,  or  other
document, or any omission (or alleged omission) to state therein a material fact
required to be stated  therein or necessary to make the  statements  therein not


                                                                            E-41


misleading,  and will reimburse the Company, such other Holders, such directors,
officers,  partners,  persons,  underwriters or control persons for any legal or
any other  expenses  reasonably  incurred in connection  with  investigating  or
defending any such claim,  loss, damage,  liability,  or action, in each case to
the extent,  but only to the  extent,  that such  untrue  statement  (or alleged
untrue statement) or omission (or alleged omission) is made in such registration
statement, prospectus, offering circular, or other document in reliance upon and
in conformity with written  information  furnished to the Company by such Holder
with the knowledge that it would be used therein,  provided that the Holder will
not be liable in any case for  amounts  paid in  settlement  of any such  claim,
loss,  damage,  liability,  or action if such settlement is effected without the
reasonable  consent  of the  Holder  (which  consent  shall not be  unreasonably
withheld).

         (c) Each party  entitled to  indemnification  under this  Section  (the
"Indemnified  Party")  shall  give  notice  to the  party  required  to  provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the  Indemnifying  Party to assume  the  defense of any such claim or any
litigation  resulting  therefrom,  provided  that  counsel for the  Indemnifying
Party,  who shall conduct the defense of such claim or any litigation  resulting
therefrom,  shall be approved by the Indemnified Party (whose approval shall not
unreasonably  be withheld),  and the  Indemnified  Party may participate in such
defense at such party's  expense,  and provided  further that the failure of any
Indemnified   Party  to  give  notice  as  provided  herein,   if  substantially
prejudicial  to the ability of the  Indemnifying  Party to defend  against  such
claim or any litigation  resulting  therefrom,  shall relieve such  Indemnifying
Party of any  obligations  under this Agreement to the extent such  Indemnifying
Party is damaged  solely as a result of such  failure to give  notice,  but such
failure  shall not relieve  such  Indemnifying  Party of any of its  obligations
otherwise than under this Agreement.  No  Indemnifying  Party, in the defense of
any such claim or litigation, shall, except with the consent of each Indemnified
Party,  consent to entry of any judgment or enter into any settlement which does
not  include as an  unconditional  term  thereof  the giving by the  claimant or
plaintiff to such  Indemnified  Party of a release from all liability in respect
to such claim or litigation.

8.       Rule  144  Reporting.  With  a view to making available the benefits of
certain  rules  and  regulations  of the SEC which  may  permit  the sale of any
outstanding Shares to the public without registration,  the Company agrees after
any registration to use its best efforts to file with the SEC in a timely manner
all reports and other documents required of the Company under the Securities Act
and the Exchange Act, as long as it is subject to such reporting requirements.

9.       Transfer of  Registration  Rights.   Subject  to  the  limitations  and
restrictions  on  transferability  of the Shares set forth in the Asset Purchase
Agreement,  the rights to cause the Company to register a Holder's  Shares under
this  Agreement may be assigned by such Holder (or its assignee) to a transferee
that  acquires  from a Holder (or its  assignee) at least fifty percent (50%) or
more of the  Registrable  Securities  originally  acquired  by the  transferring
Holder,  provided  that the Company is given notice by the Holder at the time of
such transfer stating the name and address of the transferee and identifying the
securities with respect to which these rights are being assigned.

10.      "Market  Stand-Off"  Agreement.  Holder  agrees,  if  requested  by the
Company or an underwriter of Common Stock (or other  securities) of the Company,
not to sell or  otherwise  transfer or dispose of any Shares of the Company held
by the Holder (other than those included in the registration) during the 120-day
period  following the effective date of a registration  statement of the Company
filed under the Securities Act.


                                                                            E-42


11.      Termination  of  Registration  Rights.  The  obligations of the Company
to  register  the  Registrable  Securities  pursuant  to  this  Agreement  shall
terminate  at the  earlier of seven (7) years  from the date  hereof or, for any
Holder,  when that  Holder is able to sell the Shares  pursuant  to SEC Rule 144
within a period of twelve (12) months.

12.      Modifications  and  Waivers.  This  Agreement  may  not  be  amended or
modified,  nor may the  rights of any party  hereunder  be  waived,  except by a
written  document that is executed by the  Purchasers  holding a majority of the
Registrable  Securities.  No waiver of any provision of this Agreement  shall be
deemed or shall constitute a waiver of any other provision hereof, nor shall any
waiver constitute a continuing waiver.

13.      Successors.  This  Agreement  is  and  shall  be binding upon and inure
to the  benefit  of the  parties  hereto  and their  respective  successors  and
assigns;  provided,  however,  that neither the Company nor the Purchasers shall
assign this  Agreement to any third party,  except in the case of the Purchasers
in accordance with Section 9 above.

14.      Rights and Obligations of Third Parties.  Nothing  in  this  Agreement,
whether  express or implied,  is intended to confer any rights or remedies under
or by reason of this  Agreement on any persons  other than the parties to it and
their  respective  successors  and  permitted  assigns,  nor is anything in this
Agreement  intended to relieve or discharge  the  obligation or liability of any
third parties to any party to this  Agreement,  nor shall any provision give any
third  party  any  right of  subrogation  or  action  against  any party to this
Agreement.

15.      Notices.  Any  notice,   request,   consent,   or  other  communication
hereunder  shall be in writing and shall be sent by one of the following  means:
(i) mailed by registered  or certified  first class air mail,  postage  prepaid;
(ii) by facsimile transmission; (iii) by reputable overnight courier; or (iv) by
personal  delivery,  and  shall be  properly  addressed  to the  Company  at its
principal  office,  and to the  Purchasers  at their  addresses  as shown in the
records of the Company,  or to such other address or addresses as the Company or
Purchasers  shall hereafter  designate to the other parties in writing.  Notices
shall be effective when sent.

16.      Entire  Agreement.  This  Agreement  and the exhibits hereto constitute
the entire  agreement  between  the  parties  hereto in  relation to the subject
matter  hereof.  Any prior  written  or oral  negotiations,  correspondence,  or
understandings relating to the subject matter hereof shall be superseded by this
Agreement and shall have no force or effect.

17.      Severability.   If  any  provision   which  is  not  essential  to  the
effectuation  of the basic purpose of this Agreement is determined by a court of
competent jurisdiction to be invalid and contrary to any existing or future law,
such  invalidity  shall not impair the operation of the remaining  provisions of
this Agreement.

18.      Headings.  The  headings  of  the Sections of this Agreement and in the
exhibits to this  Agreement are inserted for  convenience  of reference only and
shall not affect the construction or interpretation of any provisions hereof.


                                                                            E-43


19.      Counterparts.   This  Agreement  may  be  executed  in  any  number  of
counterparts,  each of which when executed and  delivered  shall be an original,
but all of which together shall constitute one and the same instrument.

20.      Governing Law.  This  Agreement  shall  be construed in accordance with
and  governed  by the laws of the State of Utah,  without  giving  effect to the
conflicts of laws provisions thereof.

21.      Jurisdiction,  Service  of  Process,  and Venue.  Any  dispute  arising
out of or in connection  with this Agreement,  including any question  regarding
its existence,  validity or termination,  shall be settled: first, by good faith
negotiation  between  the  parties  for a period  of no more  than ten (10) days
following  written  notice by the  disputing  party to the  other  Party of such
dispute;  then, if unresolved,  by non-binding  mediation for a period of thirty
(30)  days  before a  mutually  satisfactory  mediator.  Any  dispute  remaining
unresolved  following  mediation shall be settled by binding arbitration in Salt
Lake  City,  UT  before a single  arbitrator  under  the  Rules of the  American
Arbitration  Association for Commercial  Disputes (as modified by this section).
Judgment upon the award rendered by the arbitrator or arbitrators may be entered
in any court having  jurisdiction  thereof,  and shall be binding on the parties
hereto.  The costs of arbitration,  including  reasonable  legal fees and costs,
shall be borne by either or both of the  Parties in whatever  proportion  as the
arbitrator or arbitrators may award.


















                                                                            E-44
