                    COMMON STOCK, PAR VALUE $0.001 PER SHARE

For VALUE  RECEIVED,  [__________]  ("Warrantholder"),  is entitled to purchase,
subject to the  provisions  of this  Warrant,  from  Catcher  Holdings,  Inc., a
Delaware  corporation  (the  "Company"),  at any time not later  than 5:00 P.M.,
Eastern time, on the Expiration  Date (as defined  above),  at an exercise price

Stock, par value $0.001 per share ("Common Stock"). The number of Warrant Shares
purchasable upon exercise of this Warrant and the Warrant Price shall be subject
to adjustment from time to time as described herein.

        Section 1.  REGISTRATION.  The  Company  shall  maintain  books  for the
transfer  and  registration  of the Warrant.  Upon the initial  issuance of this
Warrant,  the Company  shall issue and  register  the Warrant in the name of the

        Section 2. TRANSFERS. A provided herein, this Warrant may be transferred
only pursuant to a  registration  statement  filed under the  Securities  Act of
1933, as amended (the "Securities Act"), or an exemption from such registration.
Subject to such restrictions,  the Company shall transfer this Warrant from time
to time upon the books to be maintained  by the Company for that  purpose,  upon
surrender  thereof for transfer  properly endorsed or accompanied by appropriate
instructions for transfer and such other documents as may be reasonably required
by the  Company,  including,  if  required  by the  Company,  an  opinion of the
Warrantholder's  counsel to the effect  that such  transfer  is exempt  from the
registration requirements of the Securities Act, to establish that such transfer
is being made in accordance  with the terms  hereof,  and a new Warrant shall be
issued to the  transferee and the  surrendered  Warrant shall be canceled by the
Company.

        Section 3. EXERCISE OF WARRANT.  Subject to the provisions  hereof,  the
Warrantholder  may exercise the Warrant in whole or in part at any time prior to
its expiration upon surrender of the Warrant, together with delivery of the duly

the  aggregate  Warrant  Price for that  number of  Warrant  Shares  then  being
purchased,  to the Company  during normal  business hours on any business day at
the Company's principal executive offices (or such other office or agency of the
Company as it may designate by notice to the Warrantholder).  The Warrant Shares
so  purchased  shall  be  deemed  to be  issued  to  the  Warrantholder  or  the
Warrantholder's  designees,  as the record owner of such shares, as of the close
of business on the date on which this Warrant  shall have been  surrendered  (or
evidence  of loss,  theft or  destruction  thereof  and  security  or  indemnity
satisfactory  to the  Company),  the Warrant  Price shall have been paid and the
completed  Exercise  Agreement shall have been delivered.  Certificates  for the
Warrant  Shares  so  purchased,  representing  the  aggregate  number  of shares
specified in the  Exercise  Agreement,  shall be delivered to the  Warrantholder
within reasonable time, not exceeding five (5) business days, after this Warrant
shall have been so exercised.  The  certificates  so delivered  shall be in such
denominations as may be requested by the  Warrantholder  and shall be registered
in the name of the  Warrantholder  or such other name as shall be  designated by
the Warrantholder. If this Warrant shall have been exercised only in

<PAGE>

part, then, unless this Warrant has expired,  the Company shall, at its expense,
at the time of delivery of such certificates, deliver to the Warrantholder a new
Warrant  representing  the number of shares  with  respect to which the  Warrant
shall not then have been exercised. As used herein,  "business day" means a day,
other than a Saturday  or Sunday,  on which  banks in New York City are open for
the general transaction of business.

        Section 4. WARRANTHOLDER REPRESENTATIONS AND WARRANTIES.

                (a)     The  Warrantholder  represents that the Warrantholder is
        an  "accredited  investor"  as such  term  is  defined  in  Rule  501 of
        Regulation D ("Regulation  D") promulgated  under the Securities Act and
        that  the  Warrantholder  is  able  to  bear  the  economic  risk  of an
        investment in the Warrants and the Common Stock.

                (b)     The Warrantholder understands that the Warrants have not
        been  registered  under  the  Securities  Act  by  reason  of a  claimed
        exemption  under the provisions of the  Securities Act that depends,  in
        part, upon the Warrantholder's investment intention. In this connection,
        the Warrantholder hereby represents that the Warrantholder is purchasing
        the Warrants for the  Warrantholder's own account for investment and not
        with  a  view  toward  the  resale  or  distribution   to  others.   The
        Warrantholder,  if an entity,  further represents that it was not formed
        for the purpose of purchasing the Warrants and the Common Stock.

                (c)     The Warrantholder  consents to the placement of a legend
        on any certificate or other document evidencing the securities that such
        securities  have not been  registered  under the  Securities  Act or any
        state  securities  or "blue sky" laws and setting  forth or referring to
        the restrictions on  transferability  and sale thereof contained in this
        Agreement.  The  Warrantholder  is aware  that the  Company  will make a
        notation in its appropriate  records with respect to the restrictions on
        the transferability of such securities.  The legend to be placed on each
        certificate  shall be in form  substantially  similar  to the legend set
        forth on the first page of this Warrant.

        Section 5. PAYMENT OF TAXES. The Company will pay any documentary  stamp
taxes  attributable to the initial  issuance of Warrant Shares issuable upon the
exercise  of the  Warrant;  provided,  however,  that the  Company  shall not be
required to pay any tax or taxes which may be payable in respect of any transfer
involved in the issuance or delivery of any certificates for Warrant Shares in a
name other than that of the  Warrantholder  in respect of which such  shares are
issued,  and in such case, the Company shall not be required to issue or deliver
any  certificate  for Warrant Shares or any Warrant until the person  requesting
the same has paid to the  Company the amount of such tax or has  established  to
the  Company's  reasonable  satisfaction  that  such  tax  has  been  paid.  The
Warrantholder shall be responsible for income taxes due under federal,  state or
other law, if any such tax is due.

        Section 6. MUTILATED OR MISSING WARRANTS.  In case this Warrant shall be
mutilated,  lost, stolen, or destroyed,  the Company shall issue in exchange and
substitution of and upon  cancellation of the mutilated  Warrant,  or in lieu of
and  substitution  for the Warrant lost,  stolen or destroyed,  a new Warrant of
like tenor and for the  purchase  of a like number of Warrant  Shares,  but only
upon receipt of evidence  reasonably  satisfactory  to the Company of such loss,
theft or  destruction  of the  Warrant,  and with  respect to a lost,  stolen or
destroyed  Warrant,  reasonable  indemnity  or bond  with  respect  thereto,  if
requested by the Company.

        Section 7.  RESERVATION OF COMMON STOCK.  The Company  hereby  covenants
that there will be  reserved,  and the  Company  shall at all  applicable  times
thereafter  keep reserved  until issued (if necessary) as  contemplated  by this
Section 7, out of the authorized and unissued shares of Common Stock, sufficient
shares to provide for the exercise of the rights of purchase represented by this
Warrant.  The Company agrees that all Warrant Shares issued upon due exercise of
the  Warrant  shall be, at the time of  delivery  of the  certificates  for such
Warrant Shares, duly authorized,  validly issued,  fully paid and non-assessable
shares of Common Stock of the Company.

        Section 8.  ADJUSTMENTS.  Subject and pursuant to the provisions of this
Section 8, unless waived in a particular case by the Warrantholder,  the Warrant
Price and number of Warrant  Shares  subject to this Warrant shall be subject to
adjustment from time to time as set forth hereinafter.
<PAGE>

                (a)     If the Company  shall,  at any time or from time to time
        while this Warrant is outstanding, pay a dividend or make a distribution
        on its Common Stock in shares of Common Stock, subdivide its outstanding
        shares of Common  Stock into a greater  number of shares or combine  its
        outstanding  shares of Common  Stock into a smaller  number of shares or
        issue by  reclassification of its outstanding shares of Common Stock any
        shares of its capital  stock  (including  any such  reclassification  in
        connection  with a  consolidation  or  merger in which  the  Company  is
        continuing  the   corporation),   then  the  number  of  Warrant  Shares
        purchasable upon exercise of the Warrant and the Warrant Price in effect
        immediately  prior to the date  upon  which  such  change  shall  become
        effective,  shall be adjusted  by the Company so that the  Warrantholder
        thereafter  exercising  the  Warrant  shall be  entitled  to receive the
        number  of  shares  of Common  Stock or other  capital  stock  which the
        Warrantholder  would have  received if the  Warrant  had been  exercised
        immediately  prior to such event upon payment of the Warrant Price. Such
        adjustments shall be made  successively  whenever any event listed above
        shall occur.

                (b)     Anything  herein to the  contrary  notwithstanding,  the
        Company  shall not be  required  to make any  adjustment  to the Warrant
        Price in the case of the  issuance  of (A)  capital  stock,  options  or
        convertible  securities  issued to  directors,  officers,  employees  or
        consultants of the Company in connection with their service as directors
        of the Company,  their  employment by the Company or their  retention as
        consultants by the Company  pursuant to an equity  compensation  program
        approved by the Board of  Directors  of the Company or the  compensation
        committee of the Board of  Directors  of the Company,  (B) shares of the
        Common  Stock  issued  upon the  conversion  or  exercise  of options or
        convertible securities issued prior to the date hereof and (C) shares of
        Common Stock issued or issuable by reason of a dividend,  stock spilt or
        other  distribution  on shares of Common  Stock  (but only to the extent
        that such a dividend,  split or distribution results in an adjustment in
        the Warrant  Price  pursuant to the other  provisions  of this  Warrant)
        (collectively, "Excluded Issuances").

        Section 9.  FRACTIONAL  INTEREST.  The Company  shall not be required to
issue  fractions  of Warrant  Shares upon the exercise of this  Warrant.  If any
fractional  share of Common Stock would,  except for the provisions of the first
sentence of this Section 9, be deliverable upon such exercise,  the Company,  in
lieu  of  delivering  such  fractional  share,   shall  pay  to  the  exercising
Warrantholder  an amount in cash  equal to the Market  Price of such  fractional
share of Common Stock on the date of exercise.

        Section 10. BENEFITS. Nothing in this Warrant shall be construed to give
any person,  firm or corporation  (other than the Company and the Warrantholder)
any legal or equitable right, remedy or claim, it being agreed that this Warrant
shall  be  for  the  sole  and   exclusive   benefit  of  the  Company  and  the
Warrantholder.

        Section 11.  NOTICES TO  WARRANTHOLDER.  Upon the happening of any event
requiring an adjustment of the Warrant  Price,  the Company shall  promptly give
written  notice  thereof to the  Warrantholder  at the address  appearing in the
records of the  Company,  stating the  adjusted  Warrant  Price and the adjusted
number of  Warrant  Shares  resulting  from  such  event  and  setting  forth in
reasonable  detail  the  method of  calculation  and the facts  upon  which such
calculation is based.  Failure to give such notice to the  Warrantholder  or any
defect  therein  shall not  affect  the  legality  or  validity  of the  subject
adjustment.

        Section 12. NOTICES.  Unless otherwise provided,  any notice required or
permitted  under  this  Warrant  shall be given in  writing  and shall be deemed
effectively  given as hereinafter  described (i) if given by personal  delivery,

request to all Holders, and subject to the limitations of this Section 2, use
commercially reasonable efforts to effect, as soon as practicable, the
registration under the Securities Act of all Registrable Securities that the
Holders request to be registered in a written request received by the Company
within twenty (20) days of the mailing of the Company's notice pursuant to this
Section 2.1.

              2.2    Notwithstanding any other provision of this Section 2, if
the Company determines, based on advice of legal counsel that it is desirable in
order to comply with the requirements of the Commission that the number of
securities to be registered (including Registrable Securities) in such
registration be reduced, then the Company shall so advise all Holders of
Registrable Securities that would otherwise be registered pursuant hereto, and
the number of shares that may be included in the registration shall be allocated
to as follows: First, to the Holders of the securities sold in the Next
Financing; and Second, to the holders of Registrable Securities under this
Agreement and to each other holder of the Company's securities that the Company
has granted, prior to the date hereof, or does grant, after the date hereof,
rights to registration, on a pro rata basis (as nearly as practicable) based on
the number of Registrable Securities or other securities held by all such
holders, provided that no Registrable Securities held by any officers or
directors of the Company shall be included in such registration unless and until
all Registrable Securities requested to be included in such registration are in
fact so included.

              2.3    In the event that (i) less than 70% of the Registrable
Securities requested to be registered by the Holders thereof under Section 2.1
above have been included in the registration statement to be filed in connection
with the Company's Next Financing (the "New Financing Registration Statement")
(such excluded securities, hereinafter referred to as the "Excluded Registrable
Securities") and (ii) the Company fails to file an additional registration
statement covering such Excluded Registrable Securities (the "Additional
Registration Statement") within ninety (90) days following the effectiveness of
the New Financing Registration Statement, the Company shall pay to each Private
Investor, at the election of each Private Investor, either (A) each Private
Investor's prorated portion of an aggregate of $45,000 or (B) each Private
Investor's prorated portion of additional Original Warrants and shares of Common
Stock that would have been purchasable in the Private Offering for an aggregate
of $45,000. Additionally, for every thirty (30) days that the Company continues
to fail to file the Additional Registration Statement (prorated for partial
periods), the Company shall pay to each Private Investor, at

<PAGE>

the election of each Private Investor, either (A) each Private Investor's
prorated portion of an aggregate of $45,000 or (B) each Private Investor's
prorated portion of additional Original Warrants and shares of Common Stock that
would have been purchasable in the Private Offering for an aggregate of $45,000.
In each case, a Private Investor's pro rata amount shall be calculated based
upon such Private Investor's percentage ownership of the total number of
Registrable Securities originally issued in the Private Offering.

              2.4    If the Initiating Holders intend to distribute the
Registrable Securities covered by their request by means of an underwriting,
they shall so advise the Company as a part of their request made pursuant to
this Section 2 and the Company shall include such information in the written
notice referred to in Section 2.1 above. In such event the right of any Holder
to include its Registrable Securities in such registration shall be conditioned
upon such Holder's participation in such underwriting and the inclusion of such
Holder's Registrable Securities in the underwriting (unless otherwise mutually
agreed by a majority in interest of the Initiating Holders and such Holder) to
the extent provided herein. All Holders proposing to distribute their securities
through such underwriting shall enter into an underwriting agreement in
customary form with the underwriter or underwriters selected for such
underwriting by the Company (which underwriter or underwriters shall be
reasonably acceptable to a majority in interest of the Initiating Holders).
Notwithstanding any other provision of this Section 2, if the underwriter
advises the Company that marketing factors require a limitation of the number of
securities underwritten (including Registrable Securities), then the Company
shall so advise all Holders of Registrable Securities that would otherwise be
underwritten pursuant hereto, and the number of shares that may be included in
the underwriting shall be allocated to the Holders of such Registrable
Securities on the same basis as set forth in Section 2.2 above. Any Registrable
Securities excluded or withdrawn from such underwriting shall be withdrawn from
the registration.

              2.5    The Company shall not be required to effect a registration
pursuant to this Section 2:

                     (a)    after the Company has effected one (1) registration
pursuant to this Section 2, and such registration has been declared or ordered
effective;

                     (b)    if the Company shall furnish to Holders requesting a
registration pursuant to this Section 2, a certificate signed by the Company's
Chief Executive Officer or Chairman of the Board stating that in the good faith
judgment of the Board of Directors of the Company, it would be seriously
detrimental to the Company and its stockholders for such registration to be
effected at such time, in which event the Company shall have the right to defer
such filing for a period of not more than one hundred twenty (120) days after
receipt of the request of the Initiating Holders, provided that such right to
delay a request shall be exercised by the Company not more than once in any
twelve (12)-month period and provided further, that the Company shall not
register any other of its shares during such one hundred twenty (120) day
period;

                     (c)    during the period starting with the date thirty (30)
days prior to the Company's good faith estimate of the date of the filing of,
and ending on a date seventy-five (75) days following the effective date of, any
registration of Company securities (other than on Form S-8 or similar forms); or

                     (d)    in any particular jurisdiction in which the Company
would be required to execute a general consent to service of process in
effecting such registration, unless the Company is already subject to service in
such jurisdiction and except as may be required under the Securities Act.

              2.6    If (but without any obligation to do so) the Company
proposes to register (including for this purpose a registration effected by the
Company for stockholders other than the Holders) any of its stock or other
securities under the Securities Act in connection with the public offering of
such securities (other than a registration relating solely to the sale of
securities to participants in a Company stock plan, a registration relating to a
corporate reorganization or other transaction under Rule 145 of the Act, a
registration on any form that does not include substantially the same
information as would be required to be included in a registration statement
covering the sale of the Registrable Securities, or a registration in which the
only Common Stock being registered is Common Stock issuable upon conversion of
debt securities that are also being registered), the Company shall, at such
time, promptly give each Holder written notice of such registration. Upon the
written request of each Holder given within twenty (20) days after mailing of
such notice by the Company, the Company shall, subject to the provisions of
Sections 2.2

<PAGE>

and 2.4 above, use its commercially reasonable efforts to cause to be registered
under the Securities Act all of the Registrable Securities that each such Holder
has requested to be registered.

              2.7    The Company shall have the right to terminate or withdraw
any registration initiated by it under this Section 2 prior to the effectiveness
of such registration whether or not any Holder has elected to include securities
in such registration. The expenses of such withdrawn registration shall be borne
by the Company in accordance with Section 5 hereof.

       3.     REGISTRATION PROCEDURES. Whenever required under this Agreement to
include Registrable Securities in a registration statement, the Company shall,
as expeditiously as commercially, reasonably possible:

              3.1    Use its commercially reasonable efforts to cause such
registration statement to remain effective until the later to occur of (A) two
(2) years from the date of this Agreement, or (B) two (2) years from the date
the Investors convert the Warrants to Common Stock, or (C) such time that all of
such Registrable Securities are no longer, by reason of Rule 144(k) under the
Securities Act, required to be registered for the sale thereof by such Holders.
The Company will also use its commercially reasonable efforts to, during the
period that such registration statement is required to be maintained hereunder,
file such post-effective amendments and supplements thereto as may be required
by the Securities Act and the rules and regulations thereunder; provided,
however, that if applicable rules under the Securities Act governing the
obligation to file a post-effective amendment permits, in lieu of filing a
post-effective amendment that (i) includes any prospectus required by Section
10(a)(3) of the Securities Act or (ii) reflects facts or events representing a
material or fundamental change in the information set forth in the registration
statement, the Company may incorporate by reference information required to be
included in (i) and (ii) above to the extent such information is contained in
periodic reports filed pursuant to Section 13 or 15(d) of the Securities
Exchange Act of 1934, as amended(the "Exchange Act"), in the registration
statement.

              3.2    Prepare and file with the Commission such amendments and
supplements to such registration statement, and the prospectus used in
connection with such registration statement, as may be necessary to comply with
the provisions of the Securities Act with respect to the disposition of all
securities covered by such registration statement.

              3.3    Upon receipt of a confidentiality agreement reasonably
acceptable to the Company, make available for inspection upon reasonable notice
during the Company's regular business hours by each Selling Holder, any
underwriter participating in any distribution pursuant to such registration
statement, and any attorney, accountant or other agent retained by such Selling
Holder or underwriter, all financial and other records, pertinent corporate
documents and properties of the Company, and cause the Company's officers,
directors and employees to supply all information reasonably requested by any
such Selling Holder, underwriter, attorney, accountant or agent in connection
with such registration statement.

              3.4    Furnish to the Selling Holders such numbers of copies of a
prospectus, including a preliminary prospectus as amended or supplemented from
time to time, in conformity with the requirements of the Securities Act, and
such other documents as they may reasonably request in order to facilitate the
disposition of Registrable Securities owned by them.

              3.5    Use its commercially reasonable efforts to register and
qualify the securities covered by such registration statement under state
securities laws of such jurisdictions as shall be reasonably requested by the
Selling Holders; provided, however, that the Company shall not be required in
connection therewith or as a condition thereto to qualify to do business or to
file a general consent to service of process in any such states or
jurisdictions, unless the Company is already subject to service in such
jurisdiction and except as may be required by the Securities Act.

              3.6    In the event of any underwritten public offering, enter
into and perform its obligations under an underwriting agreement, in usual and
customary form, with the managing underwriter of such offering. Each Selling
Holder participating in such underwriting shall also enter into and perform its
obligations under such an agreement.
<PAGE>

              3.7    Notify each Holder of Registrable Securities covered by
such registration statement, at any time when a prospectus relating thereto is
required to be delivered under the Securities Act: (i) when the registration
statement or any post-effective amendment and supplement thereto has become
effective; (ii) of the issuance by the Commission of any stop order or the
initiation of proceedings for that purpose (in which event the Company shall
make every reasonable effort to obtain the withdrawal of any order suspending
effectiveness of the registration statement at the earliest possible time or
prevent the entry thereof); (iii) of the receipt by the Company of any
notification with respect to the suspension of the qualification of the
Registrable Securities for sale in any jurisdiction or the initiation of any
proceeding for such purpose; and (iv) when the Company notifies the Commission
of the happening of any event as a result of which the prospectus included in
such registration statement, as then in effect, includes an untrue statement of
a material fact or omits to state a material fact required to be stated therein
or necessary to make the statements therein not misleading in the light of the
circumstances then existing.

              3.8    Cause all such Registrable Securities registered hereunder
to be listed on each securities exchange or quotation service on which similar
securities issued by the Company are then listed or quoted.

              3.9    Provide a transfer agent and registrar for all Registrable
Securities registered pursuant hereto and with the CUSIP number for all such
Registrable Securities, in each case not later than the effective date of such
registration.

              3.10   Cooperate with the Selling Holders and the managing
underwriters, if any, to facilitate the timely preparation and delivery of
certificates representing the Registrable Securities to be sold, which
certificates will not bear any restrictive legends; and enable such Registrable
Securities to be in such denominations and registered in such names as the
managing underwriters, if any, shall request at least two business days prior to
any sale of the Registrable Securities to the underwriters.

              3.11   Comply with all applicable rules and regulations of the
Commission.

              3.12   If the offering is underwritten and at the request of any
Selling Holder, use its commercially reasonable efforts to furnish on the date
that Registrable Securities are delivered to the underwriters for sale pursuant
to such registration: (i) opinions dated such date of counsel representing the
Company for the purposes of such registration, addressed to the underwriters and
the transfer agent for the Registrable Securities so delivered, respectively, to
the effect that such registration statement has become effective under the
Securities Act and such Registrable Securities are freely tradable, and covering
such other matters as are customarily covered in opinions of issuer's counsel
delivered to underwriters and transfer agents in underwritten public offerings
and (ii) a letter dated such date from the independent public accountants who
have certified the financial statements of the Company included in the
registration statement or the prospectus, covering such matters as are
customarily covered in accountants' letters delivered to underwriters in
underwritten public offerings.

       4.     FURNISH INFORMATION. It shall be a condition precedent to the
obligation of the Company to take any action with respect to the Registrable
Securities of any Selling Holder that such Holder shall furnish to the Company
such information regarding the Holder, the Registrable Securities held by the
Holder, and the intended method of disposition of such securities as shall be
reasonably required by the Company to effect the registration of such Holder's
Registrable Securities.

       5.     REGISTRATION EXPENSES. The Company shall bear and pay all
Registration Expenses incurred in connection with any registration, filing or
qualification of Registrable Securities with respect to registrations pursuant
for each Holder, but excluding underwriting discounts and commissions relating
to Registrable Securities and excluding any costs to any of the Holders,
including without limitation, for accounting, financial, legal or other
professional advisors to any of the Holders.

       6.     UNDERWRITING REQUIREMENTS. In connection with any offering
involving an underwriting of shares of the Company's capital stock, in addition
to the limitations set forth in Section 2.4 above, the Company shall not be
required to include any of the Holders' Registrable Securities in such
underwriting unless they accept the terms of the underwriting as agreed upon
between the Company and the underwriters selected by it (or by other persons
entitled

<PAGE>

to select the underwriters), and then only in such quantity as the underwriters
determine in their sole discretion will not jeopardize the success of the
offering by the Company.

       7.     DELAY OF REGISTRATION. No Holder shall have any right to obtain or
seek an injunction restraining or otherwise delaying any registration hereunder
as the result of any controversy that might arise with respect to the
interpretation or implementation of this Article.

       8.     INDEMNIFICATION. In the event that any Registrable Securities are
included in a registration statement under this Agreement:

              8.1    To the extent permitted by law, the Company will indemnify
and hold harmless each Holder, any underwriter (as defined in the Securities
Act) for such Holder and each person, if any, who controls such Holder or
underwriter within the meaning of the Securities Act or the Exchange Act,
against any losses, claims, damages, or liabilities (joint or several) to which
they may become subject under the Securities Act, or the Exchange Act, insofar
as such losses, claims, damages, or liabilities (or actions in respect thereof)
arise out of or are based upon any of the following statements, omissions or
violations (collectively a "Violation") in connection with the Company's
obligations under this Agreement: (i) any untrue statement of a material fact
contained in such registration statement, including any preliminary prospectus
or final prospectus contained therein or any amendments or supplements thereto,
(ii) the omission to state therein a material fact required to be stated
therein, or necessary to make the statements therein made, under the
circumstances in which they were made, not misleading, or (iii) any violation by
the Company of the Securities Act, the Exchange Act, or any rule or regulation
promulgated under the Securities Act, or the Exchange Act, and the Company will
pay to each such Holder, underwriter or controlling person, as incurred, any
legal or other expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, damage, liability, or action;
provided, however, that the indemnity agreement contained in this Section 8.1.
shall not apply to amounts paid in settlement of any such loss, claim, damage,
liability, or action if such settlement is effected without the consent of the
Company, nor shall the Company be liable in any such case for any such loss,
claim, damage, liability, or action to the extent that it arises out of or is
based upon a Violation which occurs in reliance upon and in conformity with
written information furnished expressly for use in connection with such
registration by any such Holder, underwriter or controlling person.

              8.2    To the extent permitted by law, each Selling Holder will
indemnify and hold harmless the Company, each of its directors, each of its
officers, each person, if any, who controls the Company within the meaning of
the Securities Act, any underwriter, any other Holder selling securities in such
registration statement and any controlling person of any such underwriter or
other Holder, against any losses, claims, damages, or liabilities (joint or
several) to which any of the foregoing persons may become subject, under the
Securities Act, or the Exchange Act, insofar as such losses, claims, damages, or
liabilities (or actions in respect thereto) arise out of or are based upon any
Violation, in each case to the extent (and only to the extent) that such
Violation occurs in reliance upon and in conformity with written information
furnished by such Holder expressly for use in connection with such registration;
and each such Holder will pay, as incurred, any legal or other expenses
reasonably incurred by any person intended to be indemnified pursuant to this
Section 8.2, in connection with investigating or defending any such loss, claim,
damage, liability, or action; PROVIDED, HOWEVER, that the indemnity agreement
contained in this Section 8.2 shall not apply to amounts paid in settlement of
any such loss, claim, damage, liability or action if such settlement is effected
without the consent of the Holder, which consent shall not be unreasonably
withheld.

              8.3    Promptly after receipt by an indemnified party under this
Section 8 of notice of the commencement of any action (including any
governmental action), such indemnified party shall, if a claim in respect
thereof is to be made against any indemnifying party under this Section 8,
deliver to the indemnifying party a written notice of the commencement thereof
and the indemnifying party shall have the right to participate in, and, to the
extent the indemnifying party so desires, jointly with any other indemnifying
party similarly notified, to assume the defense thereof with counsel selected by
the indemnifying party and approved by the indemnified party (whose approval
shall not be unreasonably withheld); provided, however, that an indemnified
party (together with all other indemnified parties which may be represented
without conflict by one counsel) shall have the right to retain one separate
counsel, with the fees and expenses to be paid by the indemnifying party, if, in
the opinion of counsel to the indemnified party, representation of such
indemnified party

<PAGE>

by the counsel retained by the indemnifying party would be inappropriate due to
actual or potential differing interests between such indemnified party and any
other party represented by such counsel in such proceeding. The failure to
deliver written notice to the indemnifying party within a reasonable time of the
commencement of any such action, if prejudicial to its ability to defend such
action, shall relieve such indemnifying party of any liability to the
indemnified party under this Section 8.

              8.4    If the indemnification provided for in this Section 8 is
held by a court of competent jurisdiction to be unavailable to an indemnified
party with respect to any loss, liability, claim, damage, or expense referred to
therein, then the indemnifying party, in lieu of indemnifying such indemnified
party hereunder, shall contribute to the amount paid or payable by such
indemnified party as a result of such loss, liability, claim, damage, or expense
in such proportion as is appropriate to reflect the relative fault of the
indemnifying party on the one hand and of the indemnified party on the other in
connection with the statements or omissions that resulted in such loss,
liability, claim, damage, or expense as well as any other relevant equitable
considerations. The relative fault of the indemnifying party and of the
indemnified party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the alleged
omission to state a material fact relates to information supplied by the
indemnifying party or by the indemnified party and the parties' relative intent,
knowledge, access to information, and opportunity to correct or prevent such
statement or omission.

              8.5    Notwithstanding the foregoing, to the extent that the
provisions on indemnification and contribution contained in an underwriting
agreement entered into in connection with an underwritten public offering are in
conflict with the foregoing provisions, the provisions in such underwriting
agreement shall control.

              8.6    The obligations of the Company and Holders under this
Section 8 shall survive the termination of this Agreement.

       9.     REPORTS UNDER SECURITIES EXCHANGE ACT OF 1934. With a view to
making available to the Holders the benefits of Rule 144 and any other rule or
regulation of the Commission that may at any time permit a Holder to sell
securities of the Company to the public without registration or pursuant to a
registration on Form S-3, the Company agrees to:

              9.1    make and keep public information available, as those terms
are understood and defined in Rule 144, at all times;

              9.2    file with the Commission in a timely manner all reports and
other documents required of the Company under the Securities Act and the
Exchange Act; and

              9.3    furnish to any Holder, so long as the Holder owns any
Registrable Securities, forthwith upon request (i) a copy of the most recent
annual or quarterly report of the Company and such other reports and documents
so filed by the Company, and (ii) such other information as may be reasonably
requested in availing any Holder of any rule or regulation of the Commission
which permits the selling of any such securities without registration or
pursuant to such form.

       10.    GENERAL.

              10.1   SEVERABILITY. The invalidity or unenforceability of any
provision of this agreement shall not affect the validity or enforceability of
any other provision of this agreement.

              10.2   SPECIFIC PERFORMANCE. In addition to any and all other
remedies that may be available at law in the event of any breach of this
agreement, each Investor shall be entitled to specific performance of the
agreements and obligations of the Company hereunder and to such other injunctive
or other equitable relief as may be granted by a court of competent
jurisdiction.

              10.3   GOVERNING LAW. NOTWITHSTANDING THE PLACE WHERE THIS
AGREEMENT MAY BE EXECUTED BY ANY OF THE PARTIES HERETO, THE PARTIES EXPRESSLY
AGREE THAT ALL THE TERMS AND PROVISIONS HEREOF SHALL BE CONSTRUED IN ACCORDANCE
