2.       Representations and Warranties.

         The Company represents and warrants to you as follows:

         (a) Corporate Action. The Company has all requisite corporate power and
authority,  and has taken all necessary corporate action, to execute and deliver
this  Agreement,  to  issue  and  deliver  the  Representative's   Warrants  and
certificates  evidencing  same,  and to authorize and reserve for issuance,  and
upon payment from time to time of the Purchase  Price to issue and deliver,  the
Units,  including  the Common  Stock and the Warrants and shares of Common Stock
underlying the Warrants.

         (b) No Violation. Neither the execution nor delivery of this Agreement,
the  consummation  of the actions herein  contemplated  nor compliance  with the
terms and  provisions  hereof will  conflict  with, or result in a breach of, or
constitute  a default  or an event  permitting  acceleration  under,  any of the
terms,  provisions or conditions of the Articles of  Incorporation  or Bylaws of
the Company or any indenture,  mortgage,  deed of trust, note, bank loan, credit
agreement,  franchise, license, lease, permit, judgment, decree, order, statute,
rule or regulation or any other agreement,  understanding or instrument to which
the Company is a party or by which it is bound.
3.       Compliance with the Act.

         (a)  Transferability of Representative's  Warrants.  You agree that the
Representative's Warrants may not be transferred, sold, assigned or hypothecated
for a period of one (1) year from the date hereof, except to (i) persons who are
officers of you; (ii) a successor to you in a merger or  consolidation;  (iii) a
purchaser of all or substantially all of your assets;  (iv) your shareholders in
the event you are liquidated or dissolved; (v) participating broker-dealers; and
(vi) persons who are officers or partners of participating broker-dealers.

         (b) Registration of Underlying  Securities.  The Underlying  Securities
issuable  upon  the  exercise  of the  Representative's  Warrants  have not been
registered under the Act. You agree not to make any sale or other disposition of
the Underlying Securities, except pursuant to a Registration Statement which has
become  effective under the Act,  setting forth the terms of such offering,  the
underwriting  discount and the  commissions  and any other  pertinent  data with
respect thereto, unless you have provided the Company with an opinion of counsel
reasonably acceptable to the Company that such registration is not required.

         (c)(1) Demand Registration.  Upon the written request of the holders of
a majority of the  Underlying  Securities at any time  commencing one year after
the date hereof and through the end of the fifth year after the date hereof, the
Company  shall  promptly  file and use its  best  efforts  to  cause  to  become
effective  an  appropriate  registration  statement  under  the  Securities  Act
covering such number of Underlying  Securities as such holders shall request and
to  register  the sale of such  Underlying  Securities  so that such  Underlying
Securities  may be sold at such times and in such manner as the holders  thereof
shall  determine,  provided,  that the holders of the Underlying  Securities are
entitled to only one demand registration and provided further,  that such demand
registration  right shall terminate upon the registration for sale to the public
of the  number of  Underlying  Securities  for which  such  holders  shall  have
requested  registration.  Registrations  under this Section  3(c)(1) shall be on
such appropriate registration form of the Securities and Exchange Commission (i)
as shall be selected by holders of a majority of the Underlying Securities so to
be  registered  and (ii) as shall  permit  the  disposition  of such  Underlying
Securities in accordance  with the method or methods of  disposition  desired by
such holders.  The Company agrees to include in any such registration  statement
all information  which holders of Underlying  Securities  being registered shall
reasonably  request.  If the  registration  pursuant  to  this  Section  3(c)(1)
involves an underwritten  offering,  the  underwriter or  underwriters  shall be
selected by the holders of a majority of Underlying Securities to be included in
such registration.

         (c)(2)  Inclusion in Registration of Other  Securities.  If at any time
commencing  one year after the date hereof and through the end of the fifth year
after  the date  hereof,  the  Company  shall  propose  the  registration  on an
appropriate  form  under  the  Act  of any  shares  of  Common  Stock  or  Other
Securities,  the  Company  shall at least 30 days  prior to the  filing  of such
Registration  Statement  give you written  notice,  or telegraphic or telephonic
notice followed as soon as practicable by written confirmation  thereof, of such
proposed  registration  and, upon written  notice,  or telegraphic or telephonic
notice followed as soon as practicable by written confirmation thereof, given to
the Company within ten (10) business days after the giving of such notice by the
Company,  shall  include  or  cause  to be  included  in any  such  Registration
Statement all or such portion of the  Underlying  Securities as you may request,
provided, however, that the Company may at any time withdraw or cease proceeding
with any such  registration  if it shall  at the  same  time  withdraw  or cease
proceeding with the  registration of such Common Stock or such Other  Securities
originally proposed to be registered.

                  Notwithstanding   any  provision  of  this  Agreement  to  the
contrary,   if  any  holder  of   Representative's   Warrants   exercises   such
Representative's  Warrants  but  shall  not  have  included  all the  Underlying
Securities in a Registration  Statement which complies with Section  10(a)(3) of
the Act,  which has been  effective for at least 30 calendar days  following the
exercise of the Representative's  Warrants, the registration rights set forth in
this  Section  3(c)(2)  shall  be  extended  until  such  time  as  (i)  such  a
Registration  Statement including such Underlying  Securities has been effective
for at least 30 calendar days or (ii) in the opinion of counsel  satisfactory to
you and  the  Company,  registration  is not  required  under  the Act or  under
applicable  state laws for  resale of the  Underlying  Securities  in the manner
proposed.

     (d) Company's Obligations in Registration.  In connection with any offering
of Underlying Securities pursuant to Section 3(c) above, the Company shall:

     (i)  Notify  you  as to  the  filing  thereof  and  of  all  amendments  or
supplements thereto filed prior to the effective date thereof;

     (ii) Comply with all applicable rules and regulations of the Commission;

                  (iii)  Notify  you  immediately,  and  confirm  the  notice in
         writing, (1) when the Registration Statement becomes effective,  (2) of
         the issuance by the Commission of any stop order or of the  initiation,
         or the  threatening,  of any proceedings  for that purpose,  (3) of the
         receipt  by  the  Company  of  any  notification  with  respect  to the
         suspension of  qualification  of the Underlying  Securities for sale in
         any  jurisdiction  or of the  initiation,  or the  threatening,  of any
         proceedings  for that purpose,  and (4) of the receipt of any comments,
         or requests for  additional  information,  from the  Commission  or any
         state regulatory  authority.  If the Commission or any state regulatory
         authority   shall   enter  such  a  stop  order  or  order   suspending
         qualification  at any time,  the  Company  will make  every  reasonable
         effort to obtain the lifting of such order as promptly as practicable;

                  (iv)  During  the time when a  Prospectus  is  required  to be
         delivered under the Act during the period required for the distribution
         of the  Underlying  Securities,  comply  so far as it is able  with all
         requirements  imposed upon it by the Act, as hereafter amended,  and by
         the Rules and Regulations promulgated thereunder,  as from time to time
         in force,  so far as necessary to permit the continuance of sales of or
         dealings in the Underlying Securities. If at any time when a Prospectus
         relating to the Underlying Securities is required to be delivered under
         the Act any event  shall  have  occurred  as a result of which,  in the
         opinion of counsel  for the  Company or your  counsel,  the  Prospectus
         relating to the Underlying  Securities as then amended or  supplemented
         includes an untrue  statement of a material  fact or omits to state any
         material  fact  required to be stated  therein or necessary to make the
         statements  therein, in the light of the circumstances under which they
         were made, not  misleading,  or if it is necessary at any time to amend
         such  Prospectus  to comply  with the Act,  the Company  will  promptly
         prepare  and file  with the  Commission  an  appropriate  amendment  or
         supplement (in form satisfactory to you);

                  (v)  Endeavor in good faith,  in  cooperation  with you, at or
         prior to the time the  Registration  Statement  becomes  effective,  to
         qualify  the  Underlying  Securities  for  offering  and sale under the
         securities  laws  relating to the  offering  or sale of the  Underlying
         Securities of such jurisdictions as you may reasonably designate and to
         continue the  qualifications in effect so long as required for purposes
         of the  sale  of the  Underlying  Securities;  provided  that  no  such
         qualification  shall be required in any jurisdiction where, as a result
         thereof, the Company would be subject to service of general process, or
         to  taxation  as  a  foreign   corporation   doing   business  in  such
         jurisdiction.  In each jurisdiction where such  qualification  shall be
         effected, the Company will, unless you agree that such action is not at
         the time  necessary  or  advisable,  file and make such  statements  or
         reports at such times as are or may  reasonably be required by the laws
         of such jurisdiction.  For the purposes of this paragraph, "good faith"
         is  defined  as the same  standard  of care and degree of effort as the
         Company will use to qualify its  securities  other than the  Underlying
         Securities;

                  (vi) Make generally  available to its security holders as soon
         as practicable, but not later than the first day of the eighteenth full
         calendar  month  following  the  effective  date  of  the  Registration
         Statement,  an  earnings  statement  (which  need not be  certified  by
         independent  public or independent  certified public accountants unless
         required  by  the  Act  or  the  rules  and   regulations   promulgated
         thereunder,  but which shall satisfy the provisions of Section 11(a) of
         the Act)  covering a period of at least twelve months  beginning  after
         the effective date of the Registration Statement;

                  (vii) After the effective date of such Registration Statement,
         prepare,  and  promptly  notify  you of the  proposed  filing  of,  and
         promptly  file  with  the  Commission,  each  and  every  amendment  or
         supplement  thereto or to any Prospectus  forming a part thereof as may
         be necessary to make any statements  therein not  misleading;  provided
         that no such amendment or supplement shall be filed if you shall object
         thereto in writing promptly after being furnished a copy thereof;

                  (viii)  Furnish to you,  as soon as  available,  copies of any
         such  Registration  Statement and each preliminary or final Prospectus,
         or  supplement  or amendment  prepared  pursuant  thereto,  all in such
         quantities as you may from time to time reasonably request;

                  (ix)  Make  such   representations   and   warranties  to  any
         underwriter of the Underlying Securities,  and use your best efforts to
         cause Company counsel to render such opinions to such  underwriter,  as
         such underwriter may reasonably request; and

                  (x) Pay all costs and expenses  incident to the performance of
         the  Company's  obligations  under  Sections  3(c) and 3(d)  including,
         without  limitation,  the  fees  and  disbursements  of  the  Company's
         auditors and legal counsel, fees and disbursements of legal counsel for
         you,  registration,  listing and filing  fees,  printing  expenses  and
         expenses in connection with the transfer and delivery of the Underlying
         Securities;   provided,   however,   that  the  Company  shall  not  be
         responsible  for   compensation   and   reimbursement  of  expenses  to
         underwriters or selling agents for the included Underlying Securities.

     (e)  Agreements  by  Warrant  Holder.  In  connection  with the filing of a
Registration Statement pursuant to Section 3(c) above, if you participate in the
offering by including the Underlying Securities owned by you, you agree:

                  (i) To furnish the Company all material information  requested
         by the Company  concerning  yourself and your holdings of securities of
         the Company and the proposed method of sale or other disposition of the
         Underlying  Securities and such other  information and  undertakings as
         shall be reasonably  required in connection  with the  preparation  and
         filing of any such Registration Statement covering all or a part of the
         Underlying  Securities and in order to ensure full  compliance with the
         Act; and

                  (ii) To  cooperate,  in good  faith,  with the Company and its
         underwriters,  if any, in connection with such registration,  including
         placing the Underlying  Securities to be included in such  Registration
         Statement in escrow or custody to facilitate the sale and  distribution
         thereof.

         (f) Indemnification.  The Company shall indemnify and hold harmless you
and any  underwriter  (as defined in the Act) for you, and each person,  if any,
who respectively  controls you or such underwriter within the meaning of Section
15 of the Act or Section 20(a) of the Exchange Act, against any loss, liability,
claim, damage and expense whatsoever (including, but not limited to, any and all
expense whatsoever reasonably incurred in investigating,  preparing or defending
against any litigation, commenced or threatened, or any claim whatsoever), joint
or several,  to which any of you or such underwriter or such controlling  person
becomes subject,  under the Act or otherwise,  insofar as such loss,  liability,
claim,  damage and expense (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 (i) a Registration Statement covering the Underlying Securities, in
the prospectus  contained therein,  or in an amendment or supplement thereto, or
(ii) in any  application  or other  document or  communication  (in this Section
collectively  called  "application")  executed by or on behalf of the Company or
based upon written information furnished by or on behalf of the Company filed in
any  jurisdiction  in order to  qualify  the  Underlying  Securities  under  the
securities laws thereof or filed with the  Commission,  or arise out of or 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 shall not be obligated to indemnify in any
such case to the extent that any such loss, claim, damage,  expense or liability
arises out of or is based upon any untrue  statement or alleged untrue statement
or omission or alleged  omission made in reliance upon, and in conformity  with,
written  information  respectively  furnished by you or such underwriter or such
controlling  person for use in the Registration  Statement,  or any amendment or
supplement thereto, or any application, as the case may be.

                  If any action is brought  against a person in respect of which
indemnity may be sought against the Company pursuant to the foregoing paragraph,
such person shall promptly  notify the Company in writing of the  institution of
such action and the Company  shall  assume the defense of the action,  including
the  employment  of  counsel  (satisfactory  to the  indemnified  person  in its
reasonable judgment) and payment of expenses.  The indemnified person shall have
the right to employ its or their own counsel in any such case,  but the fees and
expenses of such counsel shall be at the expense of such  indemnified  person or
unless the  employment of such counsel shall have been  authorized in writing by
the Company in  connection  with the defense of the action or the Company  shall
not have  employed  counsel to have  charge of the  defense of the action or the
indemnified  person shall have  reasonably  concluded that there may be defenses
available  to it or them  which  are  different  from  or  additional  to  those
available to the Company (in which case the Company  shall not have the right to
direct the defense of the action on behalf of the indemnified person), in any of
which events, these fees and expenses shall be borne by the Company. Anything in
this paragraph to the contrary notwithstanding,  the Company shall not be liable
for any settlement of any claim or action effected  without its written consent.
The  Company's  indemnity  agreements  contained in this Section shall remain in
full force and effect  regardless of any  investigation  made by or on behalf of
any indemnified person, and shall survive any termination of this Agreement. The
Company agrees  promptly to notify you of the  commencement of any litigation or
proceedings  against  the  Company  or any  of  its  officers  or  directors  in
connection with the Registration Statement pursuant to Section 3(c) above.

                  If you choose to include any Underlying Securities in a public
offering  pursuant to Section 3(c) above,  then you agree to indemnify  and hold
harmless the Company and each of its  directors and officers who have signed any
such Registration Statement,  and any underwriter for the Company (as defined in
the Act), and each person,  if any, who controls the Company or such underwriter
within  the  meaning  of the Act,  to the same  extent as the  indemnity  by the
Company in this Section 3(f),  but only with respect to statements or omissions,
if any,  made in such  Registration  Statement,  or any  amendment or supplement
thereto, or in any application in reliance upon, and in conformity with, written
information  furnished  by you  to  the  Company  for  use  in the  Registration
Statement,  or any amendment or supplement thereto,  or any application,  as the
case may be. In case any action  shall be brought in respect of which  indemnity
may be sought  against  you,  you shall have the rights and duties  given to the
Company,  and the persons so indemnified  shall have the rights and duties given
to you by the provisions of the first paragraph of this Section.

                  The Company  further agrees that, if the indemnity  provisions
of the  foregoing  paragraphs  are held to be  unenforceable,  any  holder  of a
Representative's  Warrant or  controlling  person of such a holder  may  recover
contribution  from the Company in an amount which,  when added to  contributions
such holder or  controlling  person has  theretofore  received  or  concurrently
receives from officers and  directors of the Company or  controlling  persons of
the Company,  will reimburse  such holder or controlling  person for all losses,
claims, damages or liabilities and legal or other expenses;  provided,  however,
that if the full amount of the  contribution  specified  in this Section 3(f) is
not permitted by law, then such holder or  controlling  person shall be entitled
to  contribution  from the Company and its officers,  directors and  controlling
persons to the full extent permitted by law.

4.       Exercise of Representative's Warrants.

         (a) Cash Exercise.  Each  Representative's  Warrant may be exercised in
full or in part (but not as to a fractional share of Common Stock) by the holder
thereof by surrender of the Warrant  Certificate,  with the form of subscription
at the end thereof duly executed by such holder, to the Company at its principal
office,  accompanied by payment, in cash or by certified or bank cashier's check
payable  to the order of the  Company,  in the  respective  amount  obtained  by
multiplying the number of Units to be purchased by the Purchase Price per Unit.

         (b) Net Exercise. Notwithstanding anything to the contrary contained in
Section 4(a), any holder of a Representative's Warrant may elect to exercise the
Representative's  Warrant  in  full  or in  part  and  receive  Units  on a "net
exercise" basis in an amount equal to the value of the Representative's  Warrant
by delivery of the form of subscription  attached to the Warrant Certificate and
surrender  of the  Representative's  Warrant  at  the  principal  office  of the
Company,  in which event the Company shall issue to the holder a number of Units
computed using the following formula:

                           X=       (P)(Y)(A-B)
                                    -----------

         Where:            X=       the number of Units to be issued to holder.

                           P=       the portion of the Representative's  Warrant

Certificate or  Certificates of like tenor, in the name of the holder thereof or
as such holder (upon payment by such holder of any  applicable  transfer  taxes)
may request  calling in the aggregate for the purchase of the number of Units of
the  Underlying  Securities  equal to the number of such Units called for on the
face of the Warrant  Certificate  (after giving effect to any adjustment therein
as provided  in Section 6 below)  minus the number of such Units  (after  giving
effect to such adjustment)  designated by the holder in the aforementioned  form
of subscription.

         (d) Company to Reaffirm  Obligations.  The Company will, at the time of
any  exercise of any  Representative's  Warrant,  upon the request of the holder
thereof,  acknowledge  in writing its  continuing  obligation  to afford to such
holder any rights (including without limitation any right to registration of the
Units  issued  upon such  exercise)  to which such holder  shall  continue to be
entitled  after  such  exercise  in  accordance  with  the  provisions  of  this
Agreement;  provided,  however, that if the holder of a Representative's Warrant
shall  fail to make  any  such  request,  such  failure  shall  not  affect  the
continuing obligation of the Company to afford to such holder any such rights.

5.       Delivery of Certificates on Exercise.

         As soon as  practicable  after  any  exercise  of any  Representative's
Warrant in full or in part, and in any event within twenty days thereafter,  the
Company at its  expense  (including  the payment by it of any  applicable  issue
taxes) will cause to be issued in the name of and  delivered  to the  purchasing
holder thereof,  a certificate or certificates  for the number of fully paid and
nonassessable  Common  Stock and Warrants to which such holder shall be entitled
upon such exercise,  plus in lieu of any  fractional  share to which such holder
would otherwise be entitled,  cash in an amount  determined  pursuant to Section
7(g),  together with any other stock or other securities and property (including
cash,  where  applicable)  to which such holder is entitled  upon such  exercise
pursuant to Section 6 below or otherwise.

6.       Anti-Dilution Provisions.

         The  Representative's  Warrants are subject to the following  terms and
conditions during the term thereof:

         (a) Subdivision and Combination.  In case the Company shall at any time
subdivide or combine the outstanding  shares of Common Stock, the Exercise Price
shall  forthwith  be  proportionately  decreased in the case of  subdivision  or
increased in the case of combination.

         (b) Stock  Dividends and  Distributions.  In case the Company shall pay
dividend  in,  or make a  distribution  of,  shares  of  Common  Stock or of the
Company's  capital stock convertible into Common Stock, the Exercise Price shall
forthwith be  proportionately  decreased.  An  adjustment  made pursuant to this
Section 6(b) shall be made as of the record date for the subject stock  dividend
or distribution.

         (c)  Adjustment in Number of  Securities.  Upon each  adjustment of the
Exercise  Price  pursuant  to the  provisions  of this  Section 6, the number of
Warrant Securities  issuable upon the exercise at the adjusted Exercise Price of
each  Warrant  shall be adjusted to the nearest  whole number by  multiplying  a
number  equal  to the  Exercise  Price  in  effect  immediately  prior  to  such
adjustment  by the number of Warrant  Securities  issuable  upon exercise of the
Warrants  immediately  prior to such  adjustment  and  dividing  the  product so
obtained by the adjusted Exercise Price.

         (d) Definition of Common Stock. For the purpose of this Agreement,  the
term "Common Stock" shall mean (i) the class of stock designated as Common Stock
in the Certificate of Incorporation of the Company as may be amended or restated
as of the  date  hereof,  or (ii)  any  other  class  of  stock  resulting  from
successive changes or  reclassifications  of such Common Stock consisting solely
of changes in par value, or from par value to no par value, or from no par value
to par value.

         (e)      Merger or Consolidation or Sale.

                  (i) In case  of any  consolidation  of the  Company  with,  or
         merger of the  Company  with,  or merger of the Company  into,  another
         corporation (other than a consolidation or merger which does not result
         in any reclassification or change of the outstanding Common Stock), the
         corporation  formed by such  consolidation  or merger shall execute and
         deliver to the Holder a supplemental  warrant agreement  providing that
         the holder of each Warrant then outstanding or to be outstanding  shall
         have the right  thereafter  (until the  expiration  of such Warrant) to
         receive,  upon exercise of such Warrant,  the kind and amount of shares
         of stock  and  other  securities  and  property  receivable  upon  such
         consolidation,  merger,  sale or  transfer by a holder of the number of
         shares of Common Stock of the Company for which such Warrant might have
         been exercised immediately prior to such consolidation, merger, sale or
         transfer.   Such  supplemental  warrant  agreement  shall  provide  for
         adjustments  which shall be  identical to the  adjustments  provided in
         this Section 6. The above provision of this subsection  shall similarly
         apply to successive consolidations or mergers.

                  (ii) In the  event  of (i) the sale by the  Company  of all or
         substantially  all of its assets, or (ii) the engagement by the Company
         or any of its  affiliates in a "Rule 13e-3  transaction"  as defined in
         paragraph  (a) (3) of Rule 13e-3 of the General  Rules and  Regulations
         under the  Securities  Exchange  Act of 1934,  as  amended,  or (iii) a
         distribution  to  the  Company's  stockholders  of  any  cash,  assets,
         property,  rights,  evidences of indebtedness,  securities or any other
         thing  of  value,  or  any  combination  thereof,  the  Holders  of the
         unexercised Warrants shall receive notice of such sale,  transaction or
         distribution  twenty  (20)  days  prior to the date of such sale or the
         record date for such transaction or distribution,  as applicable,  and,
         if they  exercise  such  Warrants  prior to such  date,  they  shall be
         entitled,  in addition to the shares of Common Stock  issuable upon the
         exercise  thereof,  to receive such  property,  cash,  assets,  rights,
         evidence of  indebtedness,  securities or any other thing of value,  or
         any combination thereof, on the payment date of such sale,  transaction
         or distribution.


         (f) No Adjustment of Exercise Price in Certain Cases.  No adjustment of
the Exercise Price shall be made if the amount of said adjustment  shall be less
than five cents ($.05) per Warrant  Security,  provided,  however,  that in such
case any  adjustment  that would  otherwise be required then to be made shall be
carried  forward  and  shall be made at the time of and  together  with the next
subsequent  adjustment  which,  together with any adjustment so carried forward,
shall amount to at least ten cents ($.10) per Warrant Security.

         (g) Notice of Change of Purchase Price. Whenever the Purchase Price per
Unit or the kind or amount of securities  purchasable under the Representative's
Warrants shall be adjusted  pursuant to any of the provisions of this Agreement,
the  Company  shall  forthwith  thereafter  cause to be sent to each holder of a
Representative's  Warrant,  a certificate  setting forth the  adjustments in the
Purchase Price per Unit and/or in such number of Unit, and also setting forth in
detail the facts requiring, such adjustments,  including,  without limitation, a
statement of the  consideration  received or deemed to have been received by the
Company  for  any  additional  shares  of  stock  issued  by it  requiring  such
adjustment.  In addition,  the Company,  at its expense,  shall,  within 90 days
following the end of each of its fiscal years during the term of this Agreement,
and promptly  upon the  reasonable  request of any holder of a  Representative's
Warrant in connection  with the exercise from time to time of all or any portion
of any Representative's  Warrant, cause independent certified public accountants
of recognized standing selected by the Company to compute any such adjustment in
accordance  with the  terms  of the  Representative's  Warrants  and  prepare  a
certificate  setting forth such  adjustment and showing in detail the facts upon
which such adjustment is based.
         (h)  Notice of a Record  Date.  In the  event of (i) any  taking by the
Company of a record of the holders of any class of securities for the purpose of
determining  the holders thereof who are entitled to receive any dividend (other
than a cash  dividend  payable  out of earned  surplus of the  Company) or other
distribution,  or any right to subscribe for,  purchase or otherwise acquire any
shares of stock of any class or any other securities or property,  or to receive
any  other  right,  (ii)  any  capital  reorganization  of the  Company,  or any
reclassification or recapitalization of the capital stock of the Company, or any
transfer  of all or  substantially  all of the  assets  of the  Company  to,  or
consolidation  or merger of the Company with or into,  any other person or (iii)
any voluntary or involuntary dissolution or liquidation of the Company, then and
in each such event the Company will mail or cause to be mailed to each holder of
a  Representative's  Warrant a notice  specifying not only the date on which any
such record is to be taken for the  purpose of such  dividend,  distribution  or
right and stating the amount and  character of such  dividend,  distribution  or
right,  but also the date on which  any such  reorganization,  reclassification,
recapitalization,  transfer, consolidation,  merger, dissolution, liquidation or
winding-up  is to take place,  and the time,  if any, as of which the holders of
record of Common Stock (or Other Securities) shall be entitled to exchange their
shares of Common Stock (or other  Securities)  for  securities or other property
deliverable  upon  such  reorganization,   reclassification,   recapitalization,
transfer,  consolidation,  merger, dissolution,  liquidation or winding-up. Such
notice shall be mailed at least  twenty (20) days prior to the  proposed  record
date therein specified.

7.       Further Covenants of the Company.

         (a) Reservation of Stock. The Company shall, at all times,  reserve and
keep  available,  solely for  issuance  and  delivery  upon the  exercise of the
Representative's  Warrants,  all  Units  from  time to time  issuable  upon  the
exercise of the  Representative's  Warrants and shall take all necessary actions
to ensure that the par value per Unit, if any, of the Underlying  Securities is,
at all times equal to or less than the then effective Purchase Price per Unit.

         (b) Title to Units. All of the Underlying Securities delivered upon the
exercise of the  Representative's  Warrants shall be validly issued,  fully paid
and nonassessable;  each holder of a Representative's Warrant shall receive good
and marketable title to the Underlying Securities,  free and clear of all voting
and other trust arrangements,  liens, encumbrances,  equities and adverse claims
whatsoever; and the Company shall have paid all taxes, if any, in respect of the
issuance thereof.

         (c) Listing on Securities  Exchanges;  Registration.  If the Company at
any time shall list any Common Stock on any national  securities  exchange,  the
Company  will,  at its  expense,  simultaneously  list  on such  exchange,  upon
official notice of issuance upon the exercise of the Representative's  Warrants,
and maintain such listing of, all of the Underlying Securities from time to time
issuable  upon the exercise of the  Representative's  Warrants;  and the Company
will so list on any  national  securities  exchange,  will so register  and will
maintain  such  listing  of,  any Other  Securities  if and at the time that any
securities  of like  class or  similar  type  shall be listed  on such  national
securities exchange by the Company.

         (d)  Exchange of  Representative's  Warrants.  Subject to Section  3(a)
hereof,  upon surrender for exchange of any Warrant  Certificate to the Company,
the Company at its expense will promptly  issue and deliver to or upon the order
of the holder thereof a new Warrant  Certificate or  certificates of like tenor,
in the name of such holder or as such holder (upon payment by such holder of any
applicable transfer taxes) may direct, calling in the aggregate for the purchase
of the  number  of  Units  called  for on  the  face  or  faces  of the  Warrant
Certificate or Certificates so surrendered.

         (e) Replacement of Representative's  Warrants. Upon receipt of evidence
reasonably  satisfactory  to the  Company  of the loss,  theft,  destruction  or
mutilation of any Warrant  Certificate  and, in the case of any such loss, theft
or destruction,  upon delivery of an indemnity agreement reasonably satisfactory
in form and amount to the Company or, in the case of any such  mutilation,  upon
surrender and  cancellation  of such Warrant  Certificate,  the Company,  at the
expense of the warrant holder will execute and deliver,  in lieu thereof,  a new
Warrant Certificate of like tenor.

         (f)  Reporting by the Company.  The Company  agrees that, if it files a
Registration Statement during the term of the Representative's Warrants, it will
use its best  efforts  to keep  current  in the  filing  of all  forms and other
materials  which it may be  required  to file  with the  appropriate  regulatory
authority pursuant to the Exchange Act, and all other forms and reports required
to be filed with any regulatory authority having jurisdiction over the Company.
         (g)  Fractional  Units.  No fractional  Units are to be issued upon the
exercise  of any  Representative's  Warrant,  but the  Company  shall pay a cash
adjustment  in  respect  of any  fraction  of a Unit which  would  otherwise  be
issuable in an amount equal to the same fraction of the highest market price per
Unit on the day of exercise, as determined by the Company.

8.       Other Holders.

         The  Representative's  Warrants are issued upon the following terms, to
all of which each holder or owner  thereof by the taking  thereof  consents  and
agrees as  follows:  (a) any person who shall  become a  transferee,  within the
limitations on transfer  imposed by Section 3(a) hereof,  of a  Representative's
Warrant properly  endorsed shall take such  Representative's  Warrant subject to
the  provisions  of Section 3(a) hereof and  thereupon  shall be  authorized  to

contained in this  Agreement,  shall be empowered to transfer  absolute title by
endorsement  and delivery  thereof to a permitted bona fide purchaser for value;
(b) each prior taker or owner waives and renounces all of his equities or rights
in such  Representative's  Warrant  in favor of each  such  permitted  bona fide
purchaser,  and each such permitted bona fide purchaser  shall acquire  absolute
title thereto and to all rights  presented  thereby;  (c) until such time as the
respective  Representative's Warrant is transferred on the books of the Company,
the  Company  may treat the  registered  holder  thereof as the  absolute  owner
thereof for all purposes, notwithstanding any notice to the contrary and (d) all
references to the word "you" in this Warrant  Agreement shall be deemed to apply
with equal effect to any person to whom a Warrant  Certificate  or  Certificates
have  been   transferred  in  accordance  with  the  terms  hereof,   and  where
appropriate, to any person holding the Underlying Securities.

9.       Miscellaneous.

         All  notices,  certificates  and  other  communications  from or at the
request of the Company to the holder of any  Representative's  Warrant  shall be
mailed by first class,  registered or certified mail,  postage prepaid,  to such

until an  address is so  furnished,  to the  address of the last  holder of such
Representative's  Warrant who has so furnished an address to the Company, except
as otherwise provided herein.  This Agreement and any of the terms hereof may be
changed,  waived,  discharged  or  terminated  only by an  instrument in writing
signed by the party against which enforcement of such change, waiver,  discharge
or  termination  is sought.  This  Agreement  shall be construed and enforced in

                            FORM OF LOCK-UP AGREEMENT

INSTITUTIONAL EQUITY CORPORATION
     As Representative of the Several Underwriters
5910 N. Central Expressway, Suite 1480
Dallas, Texas 75206


Ladies and Gentlemen:

         The  undersigned  understands  that you, as the  Representative  of the
several underwriters (the "Underwriters"), propose to enter into an Underwriting
Agreement (the  "Underwriting  Agreement") with Aarica  Holdings,  Inc., a Texas

filed with the Securities and Exchange Commission.

         In consideration of the Underwriters'  Agreement to purchase the Units,
and for  other  good and  valuable  consideration,  receipt  of which is  hereby
acknowledged,  the undersigned hereby agrees that during the period beginning on
the date of this letter and ending one (1) year (the "Lock-Up Period") after the
date of the final  prospectus  relating to the offer and sale of the Units,  the
undersigned will not,  directly or indirectly,  offer,  sell,  contract to sell,
grant any option for the sale of, pledge, or otherwise dispose of (individually,
a "Disposition") any Common Stock, or securities  exercisable,  convertible,  or
exchangeable for or into Common Stock (collectively, the "Securities"), that the
undersigned  now owns or will own in the  future  (beneficially  or of  record),
except (i) as a bona fide gift or gifts,  provided  the donee or donees  thereof
agree in writing to be bound by this Lock-Up  Agreement,  or (ii) with the prior
written consent of the  Representative.  The foregoing  restriction is expressly
agreed to  preclude  the holder of  Securities  from  engaging in any hedging or
other  transaction  which is  designed to or  reasonably  expected to lead to or
result in a Disposition of Securities  during the Lock-Up  Period,  even if such
Securities  would be disposed  of by someone  other than the  undersigned.  Such
prohibited hedging or other transactions would include, without limitation,  any
short  sale or any  purchase,  sale or grant of any  right  (including,  without
limitation,  any put or call option) with respect to any security  (other than a
broad-based  market  basket or index) that  includes,  relates to or derives any
significant part of its value from the Securities.

                                                              Sincerely,


Date: ___________  ____, 2000

                                                                   ----
