Burstware Conductor is installed.

     "Burstware  License  Key"  means the  unique,  encrypted  software  program
provided by Burst (only upon  payment of the  applicable  license  fees) that is
designed to prevent use of the Licensed Software beyond the scope of the license
paid for by Eagle by limiting, as appropriate,  and in addition to other limits,
the number of Concurrent  Burstware  Player  Connections,  the amount of Managed
Bandwidth,  and the number of Burstware Servers that the Burstware Conductor can
manage.

     "Burstware  Player(TM)"  means  the  computer  program  included  among the
Licensed  Software that operates on a single-user  client  computer,  permitting
that  computer to receive and play audio and/or video  content  delivered by the

connections   between  Burstware  Players  installed  on  client  computers  and
Burstware  Servers  installed on hardware servers that the Burstware License Key
enables the Burstware Conductor to manage simultaneously.

secrets, trademarks, trade names and other proprietary rights.

     "Licensed Software" means Burst's Burstware Conductor, Burstware Server and
Burstware Player  (collectively  "Burstware")  computer.  Licensed Software does

procured by Burst after the Effective Date of this Agreement.

     "Licensed  Territory"  means the  United  States  and its  territories  and
possessions.

     "Merger  or Sale"  shall mean a merger,  acquisition  or  consolidation  of
either party with, into or by any other  corporation or corporations,  or a sale
of all or  substantially  all of the  assets  of such  party,  resulting  in the
stockholders of such party  immediately  prior to such transaction  holding less
than a majority of the  outstanding  voting  equity  securities of the surviving
corporation  in such  merger,  consolidation,  acquisition  or  sale  of  assets
reorganization (other than a bona fide equity financing resulting in proceeds to
such party's capital accounts).

     "Program Error" means a program defect or "bug" sufficiently  material that
it results in a version of the Licensed Software, in the form delivered by Burst
to  Eagle,  at  the  time  it  is  delivered  by  Burst  to  Eagle,  failing  to
substantially  conform to the Documentation for that version. A respect in which
the Licensed Software fails to substantially  conform to the Documentation shall

computer  system already in its possession or on a computer  system  supplied to
Burst by Eagle.

     "Trademarks"  means the  trademarks  listed in Exhibit  B, which  Burst may
amend at any time upon thirty (30) days prior written notice to Eagle.

shall be a version 2.0 and all  subsequent  future  releases  during the license
period of Burst's general release software.

2.   GRANT OF LICENSE

     2.1 Terms and  Conditions.  On the terms and conditions of this  Agreement,
and upon  payment  of all  applicable  license  fees,  Burst  grants  to Eagle a
non-exclusive  (except  as set forth in  Section  2.3  below),  non-transferable
license to: (a) install and use Burstware in machine-readable,  object code form
only in the  configuration  and to the scope  identified  in and  enabled by the
Burstware  License Key(s) provided by Burst; and (b) to deploy Eagle's Burstware
License across multiple servers and locations.

     2.2 Effective  Date. The term of the license will commence upon the earlier
of (i) Eagle's first commercial  deployment of the Burstware  software,  or (ii)
January 1, 2002.

     2.3 Exclusive Period. For a period of two (2) years from the effective date
of this Agreement, Eagle will be granted a license that provides for exclusivity
in the  field-of-use:  for fiber and  wireless to the home market for  broadband
services to gated residential communities, including multi-dwelling units (i.e.,
apartment complexes);  and hospitality venues (i.e., hotel and motel complexes).
Except as expressly stated in this section, the license and rights granted under
this  Agreement  are  non-exclusive,  and  nothing  in this  Agreement  shall be
construed  as granting to Eagle any  exclusive  rights with respect to any other
field of use.

     2.4 Exclusivity  Carve-Out.  All existing  customers with licenses covering
the field-of-use identified in paragraph 2.3 are grandfathered. Any parties with
whom Burst is  currently

                                       3
<PAGE>

in negotiations for purposes of licensing, merger, acquisition, or an asset sale
as of January 31,  2001 are also  grandfathered  and covered by the  language of
this exemption.

     2.5 Extension of Exclusive Period. Eagle shall be entitled at its option to
extend the  Exclusive  Period for an  additional  twelve (12) months on the same
terms and conditions,  provided Eagle purchases at least an additional  $200,000
of client licenses during the initial 24-month term.

     2.6  Licensed  Territory.   The  United  States  and  its  territories  and
possessions.

     2.7 License Fees. The initial  Burstware  license term of 12 months will be
extended to 24 months.  In  consideration  of the extended  license term granted
herein,  Eagle will prepay to Burst a non-refundable and non-creditable  license
fee of $250,000.

     2.8 Form of Payment.  The  initial  license fee will be paid in the form of
130,000  shares of "free  trading"  common  stock of  Clearworks.net,  Inc.,  an
American Stock Exchange company with ticker symbol "CLW." Said common stock will
convert to 104,600  shares of freely  tradable  Eagle stock on January 31, 2001,
the closing date of the acquisition of Clearworks by Eagle.  Said stock transfer
and  merger  transaction  are  defined  more  fully in the  Securities  Purchase
Agreement  dated  January  30,  2001 and  attached  as Exhibit  A. 1.7  Payment.
Software  fees under the  initial  license  term shall be due and payable on the
date of the signing of this  Agreement in Clearworks  common stock and converted
into Eagle common stock as described  in Exhibit A.  Additional  client  license
fees shall be paid in cash due within  thirty (30) days  following the date upon
which the key is delivered.

     2.10 Annual  Renewal.  Upon  expiration of the initial  24-month  term, the
license will be renewable annually for a fee equal to 30% of the initial cost of
the client licenses being renewed.

     2.11 Waiver of Annual Renewal. In the event of a Burst merger or asset sale
prior to the end of Eagle's 144 holding  period or the effective  date of an S-1
registration of Burst common stock (stock received in exchange for an investment
in Burst,  see,  attached  Exhibit A),  Eagle's Burst shares will be, at Eagle's
option,  liquidated  for a value  equal  to the  value  received  by  owners  of
freely-tradable  Burst common stock. If the liquidation  value of Burst stock is
less than $0.50,  Eagle's  Burst  license  will be extended an  additional  (12)
months at no additional cost to Eagle.

     2.12  Renewal of License Upon  Acquisition  of  Burst.Com.  If Burst or its
assets  are  acquired  during  the  term of  Eagle's  software  license,  and if
Burstware technology is subsequently embodied in a new software package marketed
by the acquiring  company,  Eagle will be accorded a license to the new software
under terms substantially  similar to the terms of the initial Burstware license
at no additional cost to Eagle.

     2.13  Documentation.  Burst grants to Eagle a non-exclusive  license to use
the Documentation in connection with Eagle's use of the Licensed Software.

     2.14 Limitation on Use. Eagle  understands and acknowledges that use of the
Licensed  Software is controlled by the Burstware License Key. Eagle may not use
the Licensed  Software  beyond the scope  enabled by the  Burstware  License Key
provided  by Burst to Eagle upon  payment of the  applicable  license  fee.  The
Licensed Software functions as three separate programs, the Burstware Conductor,
Burstware Server, and Burstware Player, that operates  cooperatively.  Eagle may
install  and use only the  number  of  copies  of the  Burstware  Conductor  and
Burstware  Server  software  specifically  enabled by the Burstware  License Key
provided to Eagle by Burst.  Eagle may install an unlimited  number of copies of
the Burstware Player software for use by Eagle,  provided Eagle does not receive
any direct payment for doing so, but may  simultaneously  use only the number of
copies of the Burstware Player specifically enabled by the Burstware License Key
provided to Eagle by Burst.  Eagle may not modify or alter the Licensed Software
or  Burstware  License  Key to  increase  the  scope of its use of the  Licensed
Software.  Further,  Eagle may not use any device,  process or computer  program
that  increases,  directly  or  indirectly,  the  scope  of use of the  Licensed
Software  enabled by the  Burstware  License Key provided to Eagle by Burst.  If
Eagle wishes to increase the scope of its licensed use of the Licensed Software,
Eagle must purchase an additional Burstware License Key from Burst.

     2.15  Back-Up  Copies.  Eagle  may make one copy of the  Licensed  Software
solely  for the  back-up  or  archival  purposes,  provided  that such copy must
contain all proprietary notices affixed to or appearing in the original copy.

     2.16 Sun Microsystems  Java(TM) Runtime Environment  Provisions.  Eagle may
not modify the Java Platform  Interface ("JPI",  identified as classes contained
with the "java" package or any sub packages of the "java" package),  by creating
additional  classes  within the JPI or  otherwise  causing  the  addition  to or
modification  of the  classes in the JPI.  In the event that Eagle  creates  any
Java-related API and distributes such API to others for application development,
Eagle must promptly publish broadly, an accurate  specification for such API for
free use by all developers of Java-based software.

     2.17  Hazardous  Environments.  The  Licensed  Software is not  designed or
intended for use in online control equipment in environments requiring fail-safe
performance, such as the operation of nuclear facilities, aircraft communication
or control systems or life support systems, in which software failure could lead
to personal injury or severe property or  environmental  damage.  Eagle warrants
that it will not use or allow the use of the Licensed Software for such purposes

     2.18  Notification of Errors. In the event that Eagle discovers any errors,
bugs or other irregularity in the Licensed Software, Eagle shall promptly notify
Burst of each  such  error,  bug or  irregularity.  For the one (1) year  period
following  the Effective  Date,  Burst will provide Eagle with all bug fixes and
error corrections that may be developed by Burst for the Licensed Software.

3.   PRICING and TAXES

     3.1 Pricing. The prices payable by Eagle to Burst on a per client basis for
the initial  software license will be an amount equal to $25.00 per client up to

enhancements,  corrections  and  modifications  to the  Licensed  Software,  all
copyrights, patents, trade secrets, or trademarks or other intellectual property
rights  protecting or pertaining to any aspect of the Licensed  Software (or any
enhancements, corrections or modifications) and the Documentation, are and shall
remain the sole and exclusive  property of Burst and, where applicable,  Burst's
suppliers.  This  Agreement  does not convey title or  ownership  to Eagle,  but
instead gives Eagle only the limited rights set forth in Sections 1 and 2. Burst
reserves all rights not expressly granted by this Agreement.

     4.2 Joint  Ownership.  Subject to negotiation  and reasonable  business and
legal  consideration,  Burst and Eagle agree to jointly file patent applications
covering  inventions  embodying  intellectual  property  and know-how of the two
companies that may result from Eagle's development of unique applications of the
Licensed Software.

     4.3 Software  Development  or  Customization.  Burst agrees to use its best
efforts to accommodate all Eagle requests for custom  enhancements to Burstware,
provided  that Eagle  shall be  responsible  for all costs  incurred by Burst in
making the modifications.  Such work is to be billed at Burst's actual cost plus
30%.

     4.4 Restrictions.  Except as expressly authorized in this Agreement,  Eagle
may not: (i) use, make,  sublicense,  rent, lease, sell, display,  distribute or
copy originals or copies of the Licensed  Software,  or to permit anyone else to
do so; (ii) modify,  create  derivative works of, reverse  engineer,  unencrypt,
decompile,  disassemble  or otherwise  translate the Licensed  Software or allow
anyone  else to do so  (except  and only to the  extent  that such  activity  is
expressly  permitted by applicable law notwithstanding  this limitation);  (iii)
remove any patent, copyright or trademark or other intellectual property notices
that may appear on any part of the Licensed Software or the  documentation;  and
(iv) assign or transfer  its rights  under this  Agreement  or its rights to the
Licensed  Software  without the prior  written  consent of Burst.

                                       6
<PAGE>

Upon any such  transfer or  assignment,  Eagle must  transfer  all copies of the
Licensed  Software and  assignee  must agree in writing to all the terms of this
Agreement.

     4.5  Transfer.  Neither  party may assign or transfer its rights under this
Agreement  or its rights to the  Licensed  Software  without  the prior  written
consent of the other party.  Upon any such transfer or assignment on the part of
Eagle, Eagle must transfer all copies of the Licensed Software and Documentation
and assignee must agree in writing to all the terms of this Agreement.  Upon any
such transfer or assignment on the part of Burst, the Transferee shall honor all
the terms of this  Agreement.  Notwithstanding  the  foregoing,  each  party may
transfer its rights under this Agreement  without the consent of the other party
in connection with a Sale or change of control of such party;  provided however,
that the acquiring party shall be bound by the terms of this Agreement.

     4.6 Proprietary  Notices.  Eagle shall not remove any patent,  copyright or
trademark or other intellectual  property notices that may appear on any part of
the Licensed Software or the Documentation.

     4.7 Trade Secrets.  Eagle acknowledges that the Licensed  Software,  in its

     4.8 Audit  Rights.  Eagle  authorizes  Burst or its  designee  to audit its
compliance with this Agreement, as Burst deems reasonable.

     4.9 Notice to Employees and Agents. Eagle will use commercially  reasonable
efforts to inform its employees,  agents and others using the Licensed  Software
under this Agreement that it may not be used, copied or transferred in violation
of this Agreement.

     4.10 Irreparable Harm. Eagle  acknowledges that money damages may not be an
adequate  remedy for any breach or  violation  of any  requirement  set forth in
Section 4 of this  Agreement  and that any such  breach or  violation  may leave
Burst  without an  adequate  remedy at law.  Eagle  therefore  agrees  that,  in
addition  to any other  remedies  available  at law,  in  equity  or under  this
Agreement,  Burst  shall  be  entitled  to  obtain  temporary,  preliminary  and
permanent   injunctive   relief,   without  bond,  from  a  court  of  competent
jurisdiction to restrain any such breach or violation.

void if Eagle alters or modifies the Licensed  Software  without  Burst's  prior
written  approval,  does not use the Licensed  Software in  accordance  with the

because of any accident, abuse or misapplication;  and (b) Eagle notifying Burst
in writing of the claimed  nonconformity  within ninety (90) days after delivery
of the Licensed  Software to Eagle.  As Burst's sole  liability and Eagle's sole

warranty  set  forth in this  Section  6.3,  Burst  may at its  option:  (i) use

                  THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED
                  FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE
                  SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"). SUCH SHARES
                  MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH
                  REGISTRATION UNLESS THE TRANSFER IS IN ACCORDANCE WITH RULE
                  144 OR SIMILAR RULE.

                  THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO
                  CERTAIN RESTRICTIONS, INCLUDING TRANSFERABILITY AND VOTING, AS
                  SET FORTH IN THE REGISTRATION RIGHTS AGREEMENT, A COPY OF
                  WHICH MAY BE OBTAINED FROM THE COMPANY.

                  The Investors and Holders of Restricted Securities consent to
the Company making a notation on its records and giving instructions to any
transfer agent regarding the Restricted Securities in order to implement the
restrictions on transfer established in this Section 2.

            2.3 Notice of Proposed Transfers. The holder of each certificate
representing Restricted Securities by acceptance thereof agrees to comply in all
respects with the provisions of this Section 2.3. Prior to any proposed sale,
assignment, transfer or pledge of any Restricted Securities (other than (i) a
transfer not involving a change in beneficial ownership, or (ii) in transactions
involving the distribution without consideration of Restricted Securities by an
Investor which is a partnership to any of its partners, or retired partners, or
to the estate of any of its partners or retired partners, (iii) a transfer to an
Affiliate, an affiliated fund, partnership or Company, which is not a competitor
of the Company, subject to compliance with applicable securities laws, or (iv)
transfers in compliance with Rule 144, so long as the Company is furnished with
satisfactory evidence of compliance with such Rule), unless there is in effect a
registration statement under the Securities Act covering the proposed transfer,
the holder thereof shall give written notice to the Company of such holder's
intention to effect such transfer, sale, assignment or pledge. Each such notice
shall describe the manner and circumstances of the proposed transfer, sale,
assignment or pledge in sufficient detail, and shall be accompanied by either of
the following, at such holder's expense: (i) a written opinion of legal counsel
who shall, and whose legal opinion shall, be reasonably satisfactory to the
Company addressed to the Company, to the effect that the proposed transfer of
the Restricted Securities may be effected

                                      -4-
<PAGE>   5
without registration under the Securities Act, or (ii) a "no action" letter from
the Commission to the effect that the transfer of such securities without
registration will not result in a recommendation by the staff of the Commission
that action be taken with respect thereto, whereupon the holder of such
Restricted Securities shall be entitled to transfer such Restricted Securities
in accordance with the terms of the notice delivered by the holder to the
Company. Each certificate evidencing the Restricted Securities transferred as
above provided shall bear, except if such transfer is made pursuant to Rule 144,
the appropriate restrictive legend set forth in Section 2.2 above, except that
such certificate shall not bear such restrictive legend if in the opinion of
counsel for such holder and in the reasonable opinion of the Company such legend
is not required in order to establish compliance with any provision of the
Securities Act.

            2.4 Removal of Restrictions on Transfer of Restricted Securities.
Any legend referred to in Section 2.2 hereof stamped on a certificate evidencing
(i) the Restricted Securities or (ii) any other securities issued in respect of
the Restricted Securities upon any stock split, stock dividend,
recapitalization, merger, consolidation or similar event and the stock transfer
instructions and record notations with respect to such security shall be removed
and the Company shall issue a certificate without such legend to the holder of
such security if such security is registered under the Securities Act, or if
such holder provides the Company with an opinion of counsel (which may be
counsel for the Company) reasonably acceptable to the Company to the effect that
a public sale or transfer of such security may be made without registration
under the Securities Act or (iii) such holder provides the Company with
reasonable assurances, which may, at the option of the Company, include an
opinion of counsel satisfactory to the Company, that such security can be sold
pursuant to Section (k) of Rule 144 under the Securities Act.

consent to service of process in effecting such registration, qualification or
compliance;

                              (3) During the period starting with the date sixty
(60) days prior to the Company's estimated date of filing of any registration
statement for the securities of the Company, and ending (except as provided
below) on the date six (6) months immediately following the effective date of
any registration statement pertaining to securities of the Company, provided
that the Company is actively employing in good faith all reasonable efforts to
cause such registration statement to become effective, and, provided, further,
that the standstill period in this clause (3) shall not apply to a registration
regarding a transaction described in subsection (a) of Rule 145 as promulgated
under the Securities Act ("RULE 145") or with respect to securities issued or
issuable under an employee benefit plan or other similar plan or agreement;

                              (4) After the Company has effected two (2) such
registrations requested by holders of at least 60% of the Series E Initiating
Holders, three (3) such registrations requested by holders of the Novation
Registrable Securities, and two (2) additional registrations pursuant to this
Section 4.1(a), and such registrations have been declared or ordered effective.
The Company shall not be obligated to effect more than one such registration
requested by the holders of the Novation Registrable Securities in any twelve
month period.

                              (5) If the Company shall furnish to such Holders a
certificate signed by the President of the Company stating that in the good
faith judgment of the Board of Directors it would be seriously detrimental to
the Company or its stockholders for a registration statement to be filed in the
near future, then the Company's obligation to use its best efforts to register,
qualify or comply under this Section 4.1 shall be deferred for a period not to
exceed ninety (90) days from the date of receipt of written request from the
Initiating Holders; provided, however, that the Company shall not exercise such
right more than once in any twelve (12) month period.

                                      -6-

            (b) Underwriting. The Company shall have the right to select one or
more underwriters to manage a registration under Section 4.1, subject to the
approval of the holders of a majority of the Registrable Securities requesting
registration, which will not be unreasonably withheld, conditioned or delayed.
If the registration described in the Registration Notice is a registered public
offering involving an underwriting, the Company shall so advise the Holders as a
part of the Registration Notice. In such event, the right of any Holder to
registration pursuant to Section 4.1 shall be conditioned upon such Holder's
participation in such underwriting and the inclusion of Registrable Securities
in the underwriting to the extent provided herein. All Holders proposing to
distribute their securities through such underwriting shall (together with the
Company) enter into an underwriting agreement in customary form with the
managing underwriter selected for such underwriting by the Company. The Company
will not include in any registration under Section 4.1 any securities other than
Registrable Securities and securities to be registered for offering and sale on
behalf of the Company without the prior written consent of the holders of a
majority of the Registrable Securities requesting registration. If the managing
underwriter(s) advise the Company in writing that in their opinion the number of
Registrable Securities and, if permitted hereunder, other securities in such
offering, exceeds the number of Registrable Securities and other securities, if
any, that can be sold in an orderly manner in such offering within a price range
acceptable to the holders of a majority of the Registrable Securities initially
requesting registration, the Company will include in such registration, prior to
the inclusion of any securities that are not Registrable Securities, the number
of Registrable Securities requested to be included that in the opinion of such
underwriters can be sold in an orderly manner within the price range of such
offering, pro rata among the respective holders thereof on the basis of the
number of Registrable Securities that each such holder has requested the Company
to include in such registration.

            If any Holder of Registrable Securities disapproves of the terms of
the underwriting, such Holder may elect to withdraw therefrom by written notice
to the Company, the managing underwriter and the Initiating Holders. The
Registrable Securities and/or other securities so withdrawn shall also be
withdrawn from registration, and such Registrable Securities shall not be
transferred in a public distribution prior to one hundred eighty (180) days
after the effective date of such registration, or such other shorter period of
time as the underwriters may require.

            4.2 Company Registration.

                  (a) Notice of Registration. If at any time or from time to
time the Company shall determine to register any of its securities, either for
its own account or the account of a security holder or holders, other than (i) a
registration with respect to securities issued or to be issued in an employee
benefit plan or other similar plan or agreement, (ii) a registration relating
solely to a transaction described in Rule 145, (iii) a registration on any form
which does not permit registration of securities of the Company for secondary
sales or (iv) a registration pursuant to Section 4.1 hereof, the Company will:

                        (i) promptly give to each Holder the Registration
Notice; and

                                      -7-
<PAGE>   8
                        (ii) include in such registration (and any related
qualification under blue sky laws or other compliance), and in any underwriting
involved therein, all the Registrable Securities specified in a written request
or requests, made within ten (10) days after receipt of the Registration Notice
from the Company, by any Holder.

                  (b) Underwriting. If the registration described in the
Registration Notice is a registered public offering involving an underwriting,
the Company shall so advise the Holders as a part of the Registration Notice. In
such event, the right of any Holder to registration pursuant to Section 4.2
shall be conditioned upon such Holder's participation in such underwriting and
the inclusion of Registrable Securities in the underwriting to the extent
provided herein. All Holders proposing to distribute their securities through
such underwriting shall (together with the Company) enter into an underwriting
agreement in customary form with the managing underwriter selected for such
underwriting by the Company. Notwithstanding any other provision of this Section
4.2, if the managing underwriter determines that marketing factors require a
limitation of the number of shares to be underwritten and all shares of any
other selling stockholders (other than Holders of Registrable Securities) have
first been excluded from such registration, the managing underwriter may limit
the Registrable Securities and other securities to be distributed through such
underwriting; provided, however, that (i) no such reduction shall reduce the
number of Registrable Securities (other than Series E Registrable Securities and
Novation Registrable Securities) included in the registration below fifteen
percent (15%) of the total amount of securities included in such registration
("AVAILABLE 15% SHARES"); (ii) no such reduction shall reduce the number of
shares of Series E Registrable Securities included in the registration below
twelve percent (12%) of the total amount of securities included in such
registration ("AVAILABLE SERIES E SHARES"); and (iii) no such reduction shall
reduce the number of shares of Novation Registrable Securities held by VHA and
UHC, respectively, included in such registration below fifteen percent (15%) (in
the case of VHA) and five percent (5%) (in the case of UHC) of the total amount
of securities included in such registration in the case of the first and second
such underwritten offerings after the issuance of the Novation Registrable
Securities or reduce the number of shares of Novation Registrable Securities
below nine and one-half percent (9.5%) (in the case of VHA) and three and
one-half percent (3.5%) (in the case of UHC) of the total number of securities
included in any subsequent registration ("AVAILABLE NOVATION SHARES"), provided,
further that for purposes of allocating the number of Registrable Securities
(other than Series E Registrable Securities and Novation Registrable Securities)
that may be included in the aggregate number of Registrable Securities (other
than Series E Registrable Securities and Novation Registrable Securities)
constituting the Available 15% Shares, the registration and underwriting shall
be allocated such that each Holder is allowed to include in the registration and
underwriting the portion of the Available 15% Shares as is equal to (x) the
number of Registrable Securities (other than Series E Registrable Securities and
Novation Registrable Securities) which such Holder timely proposed to include in
such registration divided by (y) the number of Registrable Securities (other
than Series E Registrable Securities and Novation Registrable Securities) which
all Holders thereof timely proposed to include in such registration; provided,
further that for purposes of allocating the number of shares of Series E
Registrable Securities that may be included in the aggregate number of shares of
Series E Registrable Securities constituting the Available Series E Shares, the
registration and underwriting shall be allocated such that each Holder is
allowed to include in the registration and

                                      -8-
<PAGE>   9
underwriting the portion of the Available Series E Shares that is equal to (x)
the number of shares of Series E Registrable Securities which such Holder timely
proposed to include in such registration divided by (y) the number of Series E
Registrable Securities which all Holders thereof timely proposed to include in
such registration; provided, further that for purposes of allocating the number
of Novation Registrable Securities that may be included in the aggregate number
of shares of Novation Registrable Securities constituting the Available Novation
Shares, the registration and the underwriting shall be allocated such that each
Holder is allowed to include the portion of Available Novation Shares that is
equal to (x) the number of shares of Novation Registrable Securities which such
Holder timely proposed to include in such registration divided by (y) the number
of Novation Registrable Securities which all Holders thereof timely proposed to
include in such registration. The Company shall so advise all Holders
distributing their securities through such underwriting of such limitation and
the number of Registrable Securities that may be included in the registration
and underwriting shall be allocated to individual Holders timely requesting
participation in such registration under Section 4.2(a), (i) so that, as nearly
as practicable, the participation of each such Holder in the number of shares
made available to the Holders by the underwriters is, subject to the preceding
sentence, in proportion to (x) the number of Registrable Securities which such
Holder timely proposed to include in such registration to (y) the number of
Registrable Securities which all Holders timely proposed to include in such
registration, or (ii) in such other manner as shall be agreed to by the Company
and such Holders of the Registrable Securities proposed to be included in such
registration; provided, however, that the number of Registrable Securities to be
included in such underwriting shall not be reduced unless all other securities
subject to registration rights are first entirely excluded from such
underwriting. No Registrable Securities excluded from the underwriting by reason
of the underwriter's marketing limitation shall be included in such
registration. To facilitate the allocation of shares in accordance with the
above provisions, the Company or the underwriters may round the number of shares
allocated to any Holder to the nearest 100 shares.

      If any Holder disapproves of the terms of any such underwriting, such
Holder may elect to withdraw therefrom by written notice to the Company and the
managing underwriter. Any Registrable Securities and/or other securities
excluded or withdrawn from such underwriting shall be withdrawn from such
registration, and shall not be transferred in a public distribution prior to
one-hundred (180) days after the effective date of such registration, or such
other shorter period of time as the underwriters may require.

                  (c) Right to Terminate Registration. The Company shall have
the right to terminate or withdraw any registration initiated by it under this
Section 4.2 prior to the effectiveness of such registration whether or not any
Holder has elected to include securities in such registration. The Registration
Expenses of such withdrawn registration shall be borne by the Company in
accordance with Section 4.4 hereof.

            4.3 Registration on Form S-3.

                  (a) If the holders of at least one percent (1%) of the
Registrable Securities then outstanding or any holder of Series E Registrable
Securities or any holder of

                                      -9-
<PAGE>   10
Novation Registrable Securities shall request that the Company file a
registration statement on Form S-3 (or any successor form to Form S-3 or any
similar short form registration statement), for a public offering of Registrable
Securities, the reasonably anticipated aggregate price to the public of which
would equal or exceed $1,000,000 and the Company is a registrant entitled to use
Form S-3 to register the Registrable Securities for such an offering (or such
successor or similar form), the Company shall use its best efforts to cause such
Registrable Securities to be registered on such form for the offering and to
cause such Registrable Securities to be qualified in such jurisdictions as the
Holder or Holders may reasonably request; provided, however, that the Company
shall not be required to effect more than one (1) registration (which has been
declared effective) pursuant to this Section 4.3 in any twelve (12) month period
for each of the Holders of the Registrable Securities, the Series E Registrable
Securities, and the Novation Registrable Securities held by UHC, respectively,
and the Company shall not be required to effect more than two (2) registrations
(which have been declared effective) pursuant to this Section 4.3 in any twelve
(12) month period for the Holders of the Novation Registrable Securities held by
VHA. The provisions of Section 4.1(b) shall be applicable to each registration
initiated under this Section 4.3.

                  (b) Notwithstanding the foregoing, the Company shall not be
obligated to take any action pursuant to this Section 4.3: (i) in any particular
jurisdiction in which the Company would be required to qualify to do business or
execute a general consent to service of process in effecting such registration,
qualification or compliance; (ii) if the Company, within ten (10) days of the
receipt of the request of the initiating Holders, gives notice of its bona fide
intention to effect the filing of a registration statement with the Commission
within ninety (90) days of receipt of such request (other than with respect to a
registration statement relating to a Rule 145 transaction, or an offering with
respect to securities issue are issuable under an employee benefit plan or other
similar plan or agreement); (iii) during the period starting with the date
ninety (90) days prior to the Company's estimated date of filing of, and ending
on the date six (6) months immediately following, the effective date of any
registration statement pertaining to securities of the Company (other than a
registration of securities in a Rule 145 transaction or with respect to
securities issued or issuable with respect to an employee benefit plan or
similar plan or arrangement), provided that the Company is actively employing in
good faith all reasonable efforts to cause such registration statement to become
effective; or (iv) if the Company shall furnish to such Holder a certificate
signed by the President of the Company stating that in the good faith judgment
of the Board of Directors it would be seriously detrimental to the Company or
its stockholders for registration statements to be filed in the near future,
then the Company's obligation to use its best efforts to file a registration
statement shall be deferred for a period not to exceed ninety (90) days from the
receipt of the request to file such registration by such Holder; provided,
however, that the Company shall not exercise such right more than once in any
twelve (12) month period.

            4.4 Expenses of Registration. All Registration Expenses incurred in
connection with all registrations pursuant to Section 4.2, in connection
with all demand registrations under Section 4.1, and in connection with the
first three (3) S-3 registrations under Section 4.3 by each of the Series E
Registrable Securities and the Novation Registrable Securities, respectively,
shall be borne by the Company. All Selling Expenses relating to

                                      -10-
<PAGE>   11
securities registered on behalf of the Holders shall be borne by the holders of
securities included in such registration pro rata with the Company and among
each other on the basis of the number of shares so registered. Notwithstanding
the foregoing sentence, if a registration proceeding begun pursuant to Section
4.1 or 4.3 is subsequently withdrawn by the Holders, either (a) if Holders of
all of the Registrable Securities to have been registered agree, then the
Holders of the Registrable Securities to have been registered shall bear all
such Registration Expenses pro rata on the basis of the number of shares to have
been registered, or (b) if all such Holders do not agree, then the Initiating
Holders will forfeit their right to one registration pursuant to such section,
and the Company shall bear such Registration Expenses. Notwithstanding the
foregoing, however, if at the time of the withdrawal, the Holders have learned
of a material adverse change in the condition, business or prospects of the
Company from that known to the Initiating Holders at the time of their request,
of which the Company had received notice prior to the time of the request, then
the Holders shall not be required to pay any of said Registration Expenses or to
forfeit the right to one demand registration or S-3 registration, as the case
may be, and the Company shall pay the same.

            4.5 Registration Procedures. In the case of each registration,
qualification or compliance effected by the Company pursuant to this Section 4,
the Company will keep each Holder advised in writing as to the initiation of
each registration, qualification and compliance and as to the completion
thereof. At its expense the Company will:

                  (a) Prepare and file with the Commission a registration
statement with respect to such securities and use its best efforts to cause such
registration statement to become and remain effective for at least one hundred
eighty (180) days or until the earlier time that the distribution described in
the Registration Statement has been completed, provided that before filing a
registration statement or prospectus or any amendments or supplements thereto,
the Company will furnish to the counsel selected by the holders of a majority of
the Registrable Securities covered by such registration statement copies of all
such documents proposed to be filed, which documents will be subject to the
review of such counsel;

                  (b) 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.

                  (c) Furnish to the Holders participating in such registration
and to the underwriters of the securities being registered such reasonable
number of copies of the registration statement, preliminary prospectus, final
prospectus and such other documents as such underwriters may reasonably request
in order to facilitate the public offering of such securities.

                  (d) Furnish, at the request of any Holder requesting
registration of Registrable Securities on the date such Registrable Securities
are delivered to the underwriters for sale in connection with a registration
pursuant to this Section 4, (i) an opinion, dated such date, of counsel
representing the Company for the purposes of such registration, in form and
substance as is customarily given to underwriters in an underwritten public
offering, addressed to

                                      -11-
<PAGE>   12
the underwriters, if any, and to the Holders requesting registration of
Registrable Securities and (ii) a letter dated such date, from the independent
accountants of the Company, in form and substance as is customarily given by
independent accountants to underwriters in an underwritten public offering,
addressed to the underwriters, if any, and to the Holders requesting
registration of Registrable Securities.

                  (e) Use its best efforts to register and qualify the
securities covered by such registration statement under such other securities or
Blue Sky laws of such U.S. jurisdiction as shall be reasonably requested by the
Holders, provided that the Company shall not be required in connection therein
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.

                  (f) 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.

                  (g) 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 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.

                  (h) Cause all such Registrable Securities registered pursuant
hereunder to be listed on each securities exchange on which similar securities
issued by the Company are then listed and to be qualified for trading on each
system on which similar securities issued by the Company are from time to time
qualified.

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

                  (j) make available for inspection by any underwriter
participating in any disposition pursuant to such registration statement and any
attorney, accountant or other agent retained by any such underwriter, all
financial and other records, pertinent corporate documents and properties of the
Company, and cause the Company's officers, directors, employees and independent
accountants to supply all information reasonably requested by any such
underwriter, attorney, accountant or agent in connection with such registration
statement;

                  (k) otherwise use its best efforts to comply with all
applicable rules and regulations of the Securities and Exchange Commission, and
make available to its security holders, as soon as reasonably practicable, an
earnings statement covering the period of at least twelve months beginning with
the first day of the Company's first full calendar quarter after the effective
date of the registration statement, which earnings statement shall satisfy the
provisions of Section 11(a) of the Securities Act and Rule 158 thereunder;

                                      -12-
<PAGE>   13
                  (l) permit any holder of Registrable Securities that might be
deemed, in the sole and exclusive judgment of such holder, to be an underwriter
or a controlling person of the Company, to participate in the preparation of
such registration or comparable statement and to require the insertion therein
of material, furnished to the Company in writing, that in the reasonable
judgment of such holder and its counsel and the Company's counsel should be
included; and

                  (m) in the event of the issuance of any stop order suspending
the effectiveness of a registration statement, or of any order suspending or
preventing the use of any related prospectus or suspending the qualification of
any Registrable Securities included in such registration statement for sale in
any jurisdiction, the Company will use its reasonable efforts promptly to obtain
the withdrawal of such order.

If any such registration or comparable statement refers to any holder by name or
otherwise as the holder of any securities of the Company and if, in the sole and
exclusive judgment of such holder, such holder is or might be deemed to be a
controlling person of the Company, such holder shall have the right to require
(a) the inclusion in such registration statement of language, in form and
substance reasonably satisfactory to such holder, to the effect that the holding
of such securities by such holder is not to be construed as a recommendation by
such holder of the investment quality of the Company's securities covered
thereby and that such holding does not imply that such holder will assist in
meeting any future financial requirements of the Company, or (b) in the event
that such reference to such holder by name or otherwise is not required by the
Securities Act or any similar federal statute then in force, the deletion of the
reference to such holder.

            4.6 Indemnification.

                  (a) The Company will indemnify each Holder, each of its
officers, directors, partners and legal counsel, and each person controlling
such Holder within the meaning of Section 15 of the Securities Act and each
underwriter, if any, and each person who controls any underwriter within the
meaning of Section 15 of the Securities Act, against all expenses, claims,
losses, damages or liabilities (or actions in respect thereof), including any of
the foregoing incurred in settlement of any litigation, commenced or threatened,
arising out of or based on any of the following (each a "VIOLATION"):

                        (i) any untrue statement (or alleged untrue statement)
                  of a material fact contained in any registration statement,
                  prospectus, offering circular or other document, or any
                  amendment or supplement thereto, incident to any such
                  registration, qualification or compliance, or

                        (ii) any omission (or alleged omission) to state therein
                  a material fact required to be stated therein or necessary to
                  make the statements therein, in light of the circumstances in
                  which they were made, not misleading, or

                                      -13-
<PAGE>   14
                        (iii) any violation or alleged violation by the Company
                  of the Securities Act, the Exchange Act or any federal or
                  state law applicable to the Company in connection with any
                  such registration, qualification or compliance;

and the Company will reimburse each such Holder, each of its officers,
directors, partners, and legal counsel and each person controlling such Holder,
each such underwriter and each person who controls any such underwriter, for any
legal and any other expenses reasonably incurred in connection with
investigating, preparing or defending any such expense claim, loss, damage,
liability or action, provided that the Company will not be liable in any such
case to the extent that any such claim, loss, damage, liability or action arises
out of or is based on any untrue statement or omission or alleged untrue
statement or omission, made in reliance upon and in conformity with written
information furnished to the Company by an instrument duly executed by such
Holder, controlling person or underwriter and stated to be specifically for use
therein, and provided further, that the indemnity agreement contained in this
Section 4.6(a) shall not apply to amounts paid in settlement of any such
expense, claim, loss, damage, liability or action if such settlement is effected
without the consent of the Company, which consent shall not be unreasonably
withheld.

                  (b) Each Holder will, if Registrable Securities held by such
Holder are included in the securities as to which such registration,
qualification or compliance is being effected, indemnify the Company, each of
its directors, officers, and legal counsel, each underwriter, if any, of the
Company's securities covered by such a registration statement, each person who
controls the Company within the meaning of Section 15 of the Securities Act, and
each other Holder, each of its officers, directors, partners and legal counsel
and each person controlling such Holder within the meaning of Section 15 of the
Securities Act, against all expenses, claims, losses, damages and liabilities
(or actions in respect thereof) arising out of or based on any Violation that is
contained in written information furnished to the Company by an instrument duly
executed by such Holder and stated to be specifically for use in such
registration, and will reimburse the Company, such Holders, such directors,
officers, persons, underwriters or control persons for any legal or any other
expenses reasonably incurred in connection with investigating or defending any
such expense, claim, loss, damage, liability or action. Notwithstanding the
foregoing, the liability of each Holder under this Section 4.6(b) shall be
limited in an amount equal to the net proceeds received by such Holder of
Registrable Securities sold as contemplated herein, provided, however, that the
indemnity agreement contained in this Section 4.6(b) shall not apply to amounts
paid in settlement of any such expense loss, claim, damage, liability or action
if such settlement is effected without the consent of the Holder, which consent
shall not be unreasonably withheld.

                  (c) Each party entitled to indemnification under this Section
4.6 (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 litigation, shall be
approved by the Indemnified Party (whose approval shall not unreasonably be
withheld), and the

                                      -14-
<PAGE>   15
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 shall not relieve the Indemnifying Party of its obligations
under this Section 4 unless the failure to give such notice is materially
prejudicial to an Indemnifying Party's ability to defend such action, and
provided, further, that the Indemnifying Party shall not assume the defense for
matters as to which there is a conflict of interest or as to which such parties
assert separate and different defenses but shall bear the expense of such
defense nevertheless.

                  (d) If the indemnification provided for in this Section 4.6 is
held by a court of competent jurisdiction to be unavailable to an Indemnified
Party with respect to any expense, loss, liability, claim, damage, or action
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 expense, loss, liability, claim,
damage, or action 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
expense, loss, liability, claim, damage, or action 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
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 and access to information. Notwithstanding the foregoing, in no event
shall the contribution by a Holder under this Section 4.6(d) exceed the net
proceeds from the offering received by such Holder, unless such Holder's
liability resulted from willful misconduct by such Holder and no person guilty
of fraudulent misrepresentation under Section 11(f) of the Securities Act shall
be entitled to contribution from a person who was not guilty of such fraudulent
misrepresentation.

                  (e) The obligations of the Company and Holders under this
Section 4.6 shall survive the completion of any offering of Registrable
Securities in a registration statement under this Section 4, and otherwise.

            4.7 Information by Holder. The Holder or Holders of Registrable
Securities included in any registration shall furnish to the Company such
information regarding such Holder or Holders, the Registrable Securities held by
them and the distribution proposed by such Holder or Holders as shall be
required in connection with any registration, qualification or compliance
referred to in this Section 4.

            4.8 Rule 144 Reporting. With a view to making available the benefits
of certain rules and regulations of the Commission which may at any time permit
the sale of the Restricted Securities, and the Novation Registrable Securities,
to the public without registration, the Company agrees to use its best efforts
to:

                  (a) Make and keep public information available, as those terms
are understood and defined in Rule 144 under the Securities Act.

                                      -15-

                  (b) 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;

                  (c) Furnish to the Investor, so long as such Investor owns any
Restricted Securities or Novation Registrable Securities, forthwith upon request
a written statement by the Company as to its compliance with the reporting
requirements of said Rule 144 and of the Securities Act and the Exchange Act, a
copy of the most recent annual or quarterly report of the Company, and such
other reports and documents of the Company and other information in the
possession of or reasonably obtainable by the Company as an Investor may
reasonably request in availing itself of any rule or regulation of the
Commission allowing an Investor to sell any such securities without
registration.

                  (d) Take such actions as are necessary to enable the Holders
to utilize Form S-3 pursuant to Section 4.3 for the sale of Registrable
Securities.

            4.9 Transfer of Registration Rights. The rights to cause the Company
to register securities granted Holders under Sections 4.1, 4.2 and 4.3 may be
assigned by a Holder to (i) a transferee or assignee who acquires at least (or
after such transfer will hold an aggregate of) 250,000 Registrable Securities
(or 215,000 shares of Series E Registrable Securities or Novation Registrable
Securities), (ii) another Holder of Registrable Securities who already possesses
registration rights, (iii) a transferee or assignee of Registrable Securities
acquiring 10% or more of the outstanding stock of the Company, (iv) a transferee
of Registrable Securities which is a subsidiary, parent, partner, limited
partner, retired partner, shareholder or Affiliate of a Holder; (v) to a
transferee of Registrable Securities who is a Holder's family member or which is
a trust for the benefit of such Holder or (vi) in the case of Novation
Registrable Securities, patrons, affiliates, members, shareholders, partners or
controlled facilities of a shareholder, partner or member, of VHA or UHC;
provided, however, the Company is, within a reasonable time after such transfer,
furnished with written notice of the name and address of such transferee or
assignee and the securities with respect to which such registration rights are
being assigned; and provided, further, that such assignment shall be effective
only if immediately following such transfer the further disposition of such
securities by the transferee or assignee is restricted under the Securities Act.

            4.10 [Intentionally Omitted]

            4.11 Termination of Registration Rights. No Holder shall be entitled
to exercise any right provided for in this Section 4 after the earlier of
(i) September 30, 2005; or (ii) the time when all Registrable Securities held by
such Holder can, in the opinion of counsel to the Company, be sold by a Holder
in a three-month period without registration under the Securities Act pursuant
to Rule 144.

            4.12 No Inconsistent Agreements. The Company will not hereafter
enter into any agreement with respect to its securities that grants
registration rights that are inconsistent with or violate the rights granted to
the holders of Registrable Securities in this Agreement. Notwithstanding
anything to the contrary herein, the Company may grant registration rights in

                                      -16-
<PAGE>   17
connection with bank financings, lease lines, corporate partnering transactions,
business acquisitions of or by the Company or to entities with which the Company
has a business relationship, provided (a) such grant is not motivated primarily
by equity financing needs and (b) such grant is approved by the Board of
Directors (with the director appointed by the Series E Registrable Securities
concurring in the case of any change to the rights that are specific to the
Series E Registrable Securities, and with the director appointed from either
Novation or VHA concurring in the case of any change to the rights that are
specific to the Novation Registrable Securities). Persons granted registration
rights pursuant to the preceding sentence may become parties to part 4 of this
Agreement with the consent of the Company.

            4.13 Adjustments Affecting Registrable Securities. The Company will
not take ny action, or permit any change to occur, with respect to its
securities for the purpose of materially and adversely affecting the ability of
the holders of Registrable Securities to include such Registrable Securities in
a registration undertaken pursuant to this Agreement, provided that this Section
4.13 shall not apply to actions or changes with respect to the Company's
business, balance sheet, earnings or revenue or with respect to equity, debt or
acquisition transactions involving the Company.

            7.1 Amendment and Waiver. Any term of this Agreement may be amended
and the observance of any term of this Agreement may be waived (either generally
or in a particular instance and either retroactively or prospectively), but only

of Novation Registrable Securities, the Holders of a majority of the Novation

changes the economic benefit of this Agreement to any party.

acknowledge that money damages may not be an adequate remedy for any breach of
the provisions of this Agreement and that any party may in its sole discretion
apply to any court of law or equity of competent jurisdiction (without posting
any bond or other security) for specific performance and for other injunctive
relief in order to enforce or prevent violation of the provisions of this
Agreement.

            7.9 Further Assurances. Each party to this Agreement hereby
covenants and agrees, without the necessity of any further consideration, to
execute and deliver any and all such further documents and take any and all such
other actions as may be reasonably necessary or appropriate to carry out the
