                                  WITNESSETH

     WHEREAS, PRTI desires to acquire certain of the assets of IBL, and IBL
desires to sell and assign such assets to PRTI in exchange for Common Stock of
PRTI, all on the terms and conditions hereinafter set forth.

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

                                   ARTICLE I
                 ACQUISITION OF IBL ASSETS AND LIABILITIES AND
                          ISSUANCE OF PRTI SECURITIES

     1.1  Definitions.  Certain capitalized terms used in the agreement are
defined in Article IX hereof; reference to a "Schedule" or "Exhibit" is, unless
                                              --------      -------
otherwise specified, to a Schedule or Exhibit to this Agreement.

     1.2  Purchase and Sale of Assets.

          (a)  At the Closing (as that term is defined in Section 1.5), upon the
               terms and conditions herein set forth, PRTI shall purchase from
               IBL, and IBL shall sell, transfer, convey and deliver to PRTI, in
               exchange for the Acquired Shares as specified in Section 1.4, all
               of those tangible and intangible assets of IBL which are
               specifically identified in Exhibit A to this Agreement (the
               "Acquired Assets") and the assumption by PRTI of the Assumed
               Liabilities as specified in Section 1.3.

          (b)  This Agreement shall not constitute an agreement to assign or
               transfer any government approvals, instrument, contract, lease,
               permit or other agreement or arrangement, or any claim, right or
               benefit arising thereunder or resulting therefrom, if an
               assignment or transfer or an attempt to make such an assignment
               or transfer without the consent of a third party would constitute
               a breach or violation thereof or affect adversely the rights of
               PRTI or IBL, and any transfer or assignment or any interest under
               any such instrument, contract, lease, permit or other agreement
               or arrangement that requires the consent of a third party shall
               be made subject to such consent or approval being obtained. In
               the

                                       1
<PAGE>

               event any such consent or approval is not obtained on or prior to
               the Closing Date, IBL shall continue to use all reasonable
               efforts to obtain such approval or consent after the Closing Date
               until such time as such consent or approval has been obtained,
               and IBL will cooperate with PRTI in any lawful and economically
               reasonable arrangement to provide that PRTI shall receive the
               benefits under any such instrument, Contract, lease, permit or
               other agreement or arrangement, including performance by IBL as
               agent, if economically feasible, provided that PRTI shall
               undertake to pay or satisfy the corresponding liabilities for the
               enjoyment of such benefit to the extent PRTI would have been
               responsible therefor if such consent or approval had been
               obtained.


     1.3  Assumption of Liabilities.  PRTI will assume, and undertake to perform
and pay, all of the debts, liabilities and obligations of IBL listed in Exhibit
B hereto.  However, PRTI will not assume, or undertake to perform or pay, any
other debt, liability or obligation of IBL of any kind whatsoever.  The debts,
liabilities and obligations of IBL to be assumed by PRTI pursuant to this
Agreement are hereinafter called the "Assumed Liabilities".

     1.4  Issuance and Purchase of the Acquired Shares.  Subject to the terms
and conditions set forth herein, at the Closing, PRTI shall issue and sell to
IBL, and IBL shall purchase from PRTI in exchange for the Acquired Assets, six
hundred twenty five thousand (625,000) fully paid and nonassessable shares of
PRTI's restricted Common Stock (the "Acquired Shares") which shares are
                                     ---------------
restricted as described in Section 2.22 below.  The Acquired Shares shall be
paid to IBL as follows:  four hundred ninety five thousand (495,000) shares

the offices of Duane, Morris & Heckscher LLP, 227 West Monroe Street, Suite
3400, Chicago, Illinois 60606, at 10:00 a.m. Chicago time, at a date and time as

foreign corporation and is in good standing under the laws of the State of
California, and California is the only State in which the ownership or use of
the Acquired Assets require such qualification (except for the jurisdictions in
which failure to so qualify would not have a Material Adverse Effect upon the
Acquired Assets).

its obligations under the Transaction Documents.

     2.4  Noncontravention.  Neither the execution and the delivery of the
Transaction Documents nor the consummation of the transactions contemplated
thereby (including the assignments referred to in Article I above) in accordance
with the terms hereof will (i) violate any constitution, statute, regulation,
rule, injunction, judgment, order, decree, ruling, charge, or other restriction
of any government, governmental agency, or court to which IBL is subject, (ii)
violate any provision of the articles of incorporation or bylaws of IBL or (iii)

security interest upon any of its assets), except where the violation, conflict,
breach, default, acceleration, termination, modification, cancellation, failure
to give notice, or security interest has been

                                       3

waived in writing or otherwise would not, individually or in the aggregate, (x)
adversely affect the legality, validity or enforceability of any of the
Transaction Documents or the transactions contemplated thereby, (y) have or
result in a material adverse effect on the Acquired Assets or (z) adversely
impair IBL's ability to perform fully on a timely basis its obligations under
any Transaction Document (any of (x), (y) or (z) a Material Adverse Effect).
Assuming satisfaction of all relevant conditions in Article IV, IBL does not
need to give any notice to, make any filing with, or obtain any authorization,
consent, or approval of any government or governmental agency in order for the
Parties to consummate the transactions contemplated by this Agreement (including
the assignments referred to in Article II above), except where the failure to
give notice, to file, or to obtain any authorization, consent, or approval would
not have a Material Adverse Effect.

     2.5  Validity.  This Agreement constitutes the legal, valid and binding
obligation of IBL, enforceable in accordance with its terms, subject to
applicable bankruptcy, insolvency, moratorium or other similar laws relating to
creditor's rights and general principles of equity and no representation is made
regarding the effect of laws relating to competition or antitrust.

     2.6  No Defaults.  Except as set forth in Schedule 2.6, IBL is not in
default: (a) under (i) its Organizational Documents, or (ii) any material
written, oral or implied contract to which IBL is a party and, to the best
Knowledge of IBL, the other party to such contract is not in default thereunder;
or (b) with respect to any order, writ, injunction or decree of any court or any
Government Entity which, in the aggregate, will, or could reasonably be expected

properties or assets, at law or in equity, or before or by any Government
Entity; or (b) governmental inquiry pending or, to the best of IBL's Knowledge,
threatened against or affecting an IBL, including without limitation any inquiry
as to the qualification of IBL to hold or receive any license or permit, and, to
the best of IBL's Knowledge, there is no basis for any of the foregoing.  IBL
has not received any opinion or memorandum or legal advice from legal counsel to
the effect that it is exposed, from a legal standpoint, to any liability that
may be material to its business, prospects, financial condition, operations,
property or affairs, or which might call into question the validity of this
Agreement or any of the securities to be issued hereunder or any action taken or
to be taken pursuant hereto or thereto.  Furthermore, Schedule 2.7 sets forth
each instance in which IBL is (a) subject to any outstanding injunction,
judgment, order, decree, ruling, or charge or (b) a party to any action, suit,

judicial or administrative agency of any federal, state, local, or foreign
jurisdiction, except where the injunction, judgment, order, decree, ruling,
action, suit, proceeding, hearing, or investigation would not have a Material
Adverse Effect on the Acquired Assets.  Except as set forth in Schedule 2.7,
there is no action or suit by IBL pending or threatened against others.

     2.8  Title to Properties; Encumbrances.

          (a)  Except as described in Schedule 2.8, IBL owns and has good and
               marketable title to, has a valid leasehold interest in, or holds
               a valid license for, the use and transfer of all of the Acquired
               Assets, and all of the Acquired Assets are free and clear of
               mortgages, pledges, security interests, liens, charges, claims,
               restrictions and other encumbrances, except for liens for current
               taxes not yet due and payable and minor imperfections of title,
               if any, not material in nature or amount and not materially
               detracting from the value or impairing the use of the Acquired
               Assets subject thereto.

          (b)  Except as described in Schedule 2.8, all of the Acquired Assets
               are in a good state of maintenance and repair. IBL is current
               with all lease and rental payments regarding the Acquired Assets.
               IBL enjoys peaceful and undisturbed possession under all leases
               which are included in the Acquired Assets, and all such leases
               are valid and subsisting in full force and effect without any
               default of IBL thereunder and, to the best of IBL's Knowledge,
               without any default thereunder of any other party thereto. To the
               Knowledge of IBL, no event has occurred and is continuing which,
               with due notice or lapse of time or both, would constitute a
               default or event of default by IBL under any such lease or
               agreement or by any other party thereto. IBL's possession of such
               property has not been disturbed and no claim has been asserted
               against IBL that is adverse to its rights in such leasehold
               interests.

     2.9  Environmental Matters. IBL has no Knowledge of any claim, has not
received any notice of any claim, and to IBL's Knowledge no proceeding has been
instituted raising any claim, against IBL or any of the Acquired Assets,
alleging any damage to the environment or violation of any Environmental Laws.
IBL has no Knowledge of any facts that would give rise to any claim, public or
private, of violation of Environmental Laws or damage to the environment
emanating from, occurring on or affecting the Acquired Assets or their use, and
IBL has not (a) stored any Hazardous Materials on any real properties which are
part of the Acquired Assets or (b) disposed of any Hazardous Materials in a
manner contrary to any Environmental Laws.

     2.10 Governmental Approvals. Except as provided in Schedule 2.10, no
registration or filing with, or consent or approval of or other action by, any
Government Entity is or will be necessary for the valid execution, delivery and
performance by IBL of this Agreement.

     2.11 Brokers. Except for the fee to be paid to ITG, no broker, investment
banker, finder, financial advisor or other Person is entitled to any broker's,
finder's, financial advisor's or

                                       5
<PAGE>

other similar fee or commission in connection with the transactions contemplated
by this Agreement based on arrangements made by or on behalf of IBL.

     2.12  Officers. To the Knowledge of IBL, no officer, employee or consultant
of IBL is now in violation of any term of any employment contract, patent
disclosure agreement, proprietary information agreement, noncompetition
agreement, nonsolicitation agreement, confidentiality agreement or any other
similar contract or agreement related to the Acquired Assets, or any restrictive
covenant relating to the right of any such officer, employee or consultant to be
employed or engaged by IBL because of the nature of the business conducted or to
be conducted by IBL or relating to the use of trade secrets or proprietary
information of others.

     2.13  Employees; Benefit Plans. IBL is not a party to any collective
bargaining agreement and is not a party to any pending or threatened labor
dispute. There is no employee of IBL whose employment is not terminable at will.
IBL has no employee benefit plans.

     2.14  Year 2000. IBL's computer system and software including all software
and applications which are part of the Acquired Assets, are able to accurately
process date data, including but not limited to, calculating, comparing and
sequencing from, into and between the twentieth century through year 1999, the
year 2000 and the twenty-first century, including leap year calculations. To the
Knowledge of IBL, it is not aware of any inability on the part of any service
provider to IBL to timely remedy such service provider's own deficiencies in
respect of the year 2000 problem.

     2.15  Tax Matters. Except as described in Schedule 2.15, there are no
encumbrances or tax liens on any of the Acquired Assets.

     2.16  Real Property. Prior to Closing, IBL will make available to PRTI
correct and complete copies of the leases and subleases (as amended to date)
which are part of the Acquired Assets. With respect to each such lease and
sublease, and except as otherwise disclosed in Schedule 2.16:

           (i)    the lease or sublease is legal, valid, binding, enforceable,
                  and in full force and effect;

           (ii)   the lease or sublease will continue to be legal, valid,
                  binding, enforceable, and in full force and effect on
                  identical terms following the consummation of the transactions
                  contemplated hereby;

           (iii)  to the best of IBL's Knowledge no party to the lease or
                  sublease is in breach or default, and no event has occurred
                  which, with notice or lapse of time, would constitute a breach
                  or default or permit termination, modification, or
                  acceleration thereunder;

                                       6
<PAGE>

           (iv)    to the best of IBL's Knowledge no party to the lease or
                   sublease has repudiated any provision thereof;

           (v)     to the best of IBL's Knowledge there are no disputes, oral
                   agreements, or forbearance programs in effect as to the lease
                   or sublease;

           (vi)    to the best of IBL's Knowledge with respect to each sublease,
                   the representations and warranties set forth in subsections
                   (i) through (v) above are true and correct with respect to
                   the underlying lease;

           (vii)   IBL has not assigned, transferred, conveyed, mortgaged,
                   deeded in trust, or encumbered any interest in the leasehold
                   or subleasehold, except for term financing existing as of the
                   date of this Agreement;

           (viii)  to the best of IBL's Knowledge all facilities leased or
                   subleased thereunder have received all approvals of
                   governmental authorities (including licenses and permits)
                   required in connection with the operation thereof and have
                   been operated and maintained in accordance with applicable
                   laws, rules, and regulations; and

           (ix)    all facilities leased or subleased thereunder are supplied
                   with utilities and other services necessary for the operation
                   of said facilities.

Acquired Assets and any other intellectual property owned by IBL, (b) each

     2.21  Sophistication. IBL has sufficient knowledge and experience in
investing in companies similar to PRTI in terms of PRTI's stage of development
so as to be able to evaluate the risks and merits of its investment in PRTI and

any security interest upon any of its assets), except where the violation,
conflict, breach, default, acceleration, termination, modification,

               entered into any transaction outside the Ordinary Course of
               Business.

     3.8  Legal Compliance. PRTI has complied with all applicable laws
(including rules, regulations, codes, plans, injunctions, judgments, orders,
decrees, rulings, and charges thereunder) of federal, state, local, and foreign
governments (and all agencies thereof), except where the failure to comply,
individually or in the aggregate would not have a Material Adverse Effect.

made and makes no representation or warranty, express or implied, at law or in

     (c)  If for any reason the indemnity provided for in this Section 5.4 is
          unavailable to any Indemnified Party or is insufficient to hold each
          such Indemnified Party harmless from all such Losses arising with
          respect to the transactions contemplated hereunder, then PRTI and the
          Indemnified Party shall each contribute to the amount paid or payable
          by such Loss in such proportion as is appropriate to reflect not only
          the relative benefits received by PRTI on the one hand, and such
          Indemnified Party on the other, but also the relative fault of PRTI on
          the one hand, and the Indemnified Party on the other, as well as any
          relevant

                                       16
<PAGE>

          equitable considerations. In addition, PRTI agrees to reimburse any
          Indemnified Party upon demand for all reasonable expenses, including
          legal counsel fees, incurred by such Indemnified Party or any such
          other person in connection with investigating, preparing or defending
          any such action or claim. The indemnity, contribution and expense
          reimbursement obligations that PRTI has under this Section 5.4 shall
          be in addition to any liability that PRTI may otherwise have. PRTI
          further agrees that the indemnification and reimbursement commitments
          set forth in this Agreement shall apply whether or not the Indemnified
          Party is a formal party to any such lawsuits, claims or other
          proceedings.

     (d)  Any indemnification of either IBL or any other Indemnified Party by
          PRTI pursuant to this Section 5.4 shall be effected by wire transfer
          of immediately available funds from PRTI to an account designated by
          IBL or such other Indemnified Party within 15 days after the
          determination thereof.

     5.5  Confidentiality. PRTI shall, and shall cause each other PRTI
Affiliated Company to, maintain in confidence, and cause their respective
directors, officers, employees, agents and advisors to maintain in confidence,
any written, oral or other information obtained in confidence from IBL in
connection with this Agreement or the contemplated transactions. If this
Agreement is terminated, PRTI shall return or destroy as much of such written
information as IBL may reasonably request.

                                  ARTICLE VI
                               COVENANTS OF IBL

prudent manner as far as is practicable in accordance with past practices, and
will use its best efforts to preserve its existing business and relationships
with its employees, customers, and others, to preserve and protect the Acquired
Assets, and to conduct its business in compliance with all applicable laws and

assets (other than inventory sold in the normal and Ordinary Course of Business
as presently conducted), and will not encumber any of the Acquired Assets, or
any other assets, rights, or interests which are subject to this Agreement. IBL
will not otherwise engage in any practice, take any action, or enter into any
transaction outside the Ordinary Course of Business. From and after the date of
this Agreement and until the Closing, IBL shall refrain from any action or
inaction with third parties that may jeopardize clean and clear title to the
Acquired Assets.

     6.2  Full Access. IBL will permit representatives of PRTI to have full
access at all reasonable times, and in a manner so as not to interfere with the
normal business operations of

                                       17

IBL, to all premises, properties, personnel, books, records (including tax
records), contracts, and documents of or pertaining to IBL.

     6.3  Exclusivity. IBL will not solicit, initiate, or encourage the
submission of any proposal or offer from any Person relating to the acquisition
of all or substantially all of the capital stock or assets of IBL (including any
acquisition structured as a merger, consolidation, or share exchange).

     6.4  Appropriate Action; Consents; Filings. IBL shall use its best efforts
to (i) take, or cause to be taken, all appropriate action, and do, or cause to
be done, all things necessary, proper or advisable under applicable Law to
consummate and make effective the transactions contemplated by this Agreement;
(ii) obtain all consents, licenses, permits, waivers, approvals, authorizations
or orders required under applicable Law (including, without limitation, all
foreign and domestic (federal, state and local) governmental and regulatory
rulings and approvals of parties to Contracts) necessary to be obtained by IBL
in connection with the authorization, execution and delivery of this Agreement
and the consummation by IBL of the transactions contemplated hereby; and (iii)
make all necessary filings, and thereafter make any other required submissions,
with respect to this Agreement required under (A) the Securities Act and the
Exchange Act and the rules and regulations promulgated thereunder, and any other
applicable federal or state securities laws; and (B) any other applicable Law.

     6.5  Indemnification.

          (a)  In addition to all rights and remedies available to PRTI at law
               or in equity, IBL shall indemnify, defend and hold harmless PRTI
               and any Indemnified Party of PRTI from and against and pay on
               behalf of or reimburse such party as and when incurred all
               losses, including, without limitation, Liabilities, demands,
               claims, actions or causes of action, costs, damages, judgments,
               debts, settlements, assessments, deficiencies, taxes, penalties,
               fines or expenses, whether or not arising out of any claims by or
               on behalf of any third party, including interest, penalties,
               reasonable attorneys' fees and expenses and all reasonable
               amounts paid in investigation, defense or settlement of any of
               the foregoing (collectively, "PRTI Losses") which any such party
                                                  ------
               may suffer, sustain or become subject to, as a result of, in
               connection with, or relating to or by virtue of:

               (v)  any material misrepresentations or material breach of
                    warranty on the part of IBL under Article II;

               (vi) any material misrepresentation in or material omission from

                    Agreement or

                                       18
<PAGE>

                      the Schedules delivered to PRTI by or on behalf of IBL in
                      connection herewith;

               (vii)  any material nonfulfillment or breach of any covenant or
                      agreement on the part of IBL under this Agreement;

               (viii) any action, demand, proceeding, investigation or claim by
                      any third party, including, without limitation, Government
                      Entities against or affecting any IBL Affiliated Company
                      or any of their affiliates which, if successful, would
                      give rise to or evidence the existence of or relate to a
                      material breach of (A) any of the material representations
                      or warranties at the time made or (B) the covenants of
                      IBL;

               (ix)   any action, demand, proceeding, investigation or claim by
                      any third party regarding the Acquired Assets whereby such
                      action, demand, proceeding, investigation or claim is
                      based upon certain agreements, actions or breaches by IBL
                      regarding the use or ownership of the Acquired Assets
                      prior to the date hereof; or

               (x)    any claims for damages, losses, diminution in value of any
                      asset which remains on the premises of 215 Castro Street,
                      Mountain View, California 94041, following the date
                      hereof.

          (b)  All indemnification rights hereunder shall survive the execution
               and delivery of this Agreement and the consummation of the
               transactions contemplated hereunder for a period of two (2) years
               regardless of any investigation, inquiry or examination made for
               or on behalf of, or any Knowledge of, PRTI and/or any of the
               other PRTI Indemnified Parties or the acceptance by PRTI of any
               certificate or opinion.

          (c)  If for any reason the indemnity provided for in this Section 6.5
               is unavailable to any PRTI Indemnified Party or is insufficient
               to hold each such PRTI Indemnified Party harmless from all such
               PRTI Losses arising with respect to the transactions contemplated
               hereunder, then IBL and the PRTI Indemnified Party shall each
               contribute to the amount paid or payable by such PRTI Loss in
               such proportion as is appropriate to reflect not only the
               relative benefits received by IBL on the one hand, and such PRTI
               Indemnified Party on the other, but also the relative fault of
               IBL on the one hand, and the PRTI Party on the other, as well as
               any relevant equitable considerations. In addition, IBL agrees to
               reimburse any PRTI Party upon demand for all reasonable expenses,
               including legal counsel

                                       19
<PAGE>

               fees, incurred by such PRTI Indemnified Party or any such other
               person in connection with investigating, preparing or defending
               any such action or claim. The indemnity, contribution and expense
               reimbursement obligations that IBL has under this Section 6.5
               shall be in addition to any liability that IBL may otherwise
               have. IBL further agrees that the indemnification and
               reimbursement commitments set forth in this Agreement shall apply
               whether or not the PRTI Indemnified Party is a formal party to
               any such lawsuits, claims or other proceedings.

          (d)  Any reimbursements owed to PRTI by IBL hereunder shall be paid by
               IBL (i) first out of the Escrow Account as described in Section
               1.4 hereof (for which purpose any Acquired Shares which are
               transferred to PRTI out of the escrow created by the Escrow
               Agreement shall be valued at the average sale price of such
               shares on the senior market or quotation system on which such
               Shares are then listed or quoted over the ten (10) trading days
               immediately preceding the date on which such Shares are so
               transferred, and (ii) then, to the extent of the balance,
               effective by wire transfer of immediately available funds from
               IBL to an account designated by PRTI or such other PRTI
               Indemnified Party within 15 days after the determination thereof.

     6.6  Confidentiality. IBL shall, and shall cause each other IBL Affiliated
Company to, maintain in confidence, and cause their respective directors,
officers, employees, agents and advisors to maintain in confidence, any written,
oral or other information obtained in confidence from PRTI in connection with
this Agreement or the contemplated transactions. If this Agreement is
terminated, IBL shall return or destroy as much of such written information as
PRTI may reasonably request.

     6.7  IBL Schedules. Within ten (10) business days of the date of this
Agreement, IBL will deliver to PRTI a set of schedules (the "IBL Schedules")

identifying (a) the Acquired Assets described in Section 1.2(d), and (b) any
exceptions to the representations and warranties of IBL set forth in Article II.

               transactions contemplated hereby shall not have been consummated
               pursuant hereto by 5:00 p.m. Chicago time on December 31, 2000,
               or such later date as may be selected by the mutual written
               consent of IBL and PRTI, provided that no party may give such
               notice if its breach of this Agreement has precluded the
               consummation of this Agreement;

          (c)  by PRTI by written notice to IBL if (i) the representations and
               warranties of IBL shall not have been true and correct in all
               respects (in the case of a representation or warranty containing
               a materiality qualification) or in all material respects (in the
               case of a representation or warranty without a materiality
               qualification) as of the date when made, or (ii) if any of the
               conditions set forth in Section 4.2 shall not have been, or if it
               becomes apparent that any of such conditions will not be,
               fulfilled by 5:00 p.m. Chicago time, on December 31, 2000, or
               such later date as may be selected by the mutual written consent
               of IBL and PRTI, unless such failure shall be due to the failure
               of PRTI to perform or comply with any of the covenants,
               agreements, or conditions hereof to be performed or complied with
               by it prior to the Closing; or

          (d)  by IBL by written notice to PRTI if (i) the representations and
               warranties of PRTI shall not have been true and correct in all
               respects (in the case of a representation or warranty containing
               a materiality qualification) or in all material respects (in the
               case of a representation or warranty without a materiality
               qualification) as of the date when made, (ii) if any of the
               conditions set forth in Section 4.1 shall not have been, or if it
               becomes apparent that any of such conditions will not be,
               fulfilled by 5:00 p.m. Chicago time, on December 31, 2000, or
               such later date may be selected by the mutual written consent of
               IBL and PRTI, unless such failure shall be due to the failure of
               IBL to perform or comply with any of the covenants, agreements,
               or conditions hereof to be performed or complied with by it prior
               to the Closing, or (iii) in the event IBL elects to terminate by
               reason of the option provided in Section 4.2(f).

     7.2  Effect of Termination. In the event of the termination of this
Agreement pursuant to Section 7.1, this Agreement shall become void, without any
liability to any party in respect hereof or the transactions contemplated hereby
on the part of any party hereto or any of their respective directors, officers,
employees, agents, consultants, representatives, advisers or shareholders,
provided, however, that: (a) nothing shall release a breaching party from
liability for damages resulting from its breach of this Agreement, and (b)
Sections 5.5, 6.6, 7.2, and Articles VIII and IX shall survive indefinitely
subject to applicable statutes of limitations.
