                        PROVANSIS LLC AN INFORTE COMPANY

                       LIMITED LIABILITY COMPANY AGREEMENT

         THIS LIMITED LIABILITY COMPANY AGREEMENT (this "Agreement") of
PROVANSIS LLC An Inforte Company, a limited liability company (the "Company")
organized pursuant to the Delaware Limited Liability Company Act, is made as of
May 20, 2005, by and among Primary Knowledge, Inc., a California corporation
("PKI"), Inforte Corp., a Delaware corporation ("Inforte"), and Ronald Meyer,
residing at 3712 Maple Circle NE, North Liberty, Iowa, 52317 ("Meyer") (and
together with PKI and Inforte, the "Members"), and, solely with respect to
Articles 4 and 15, Jerry Conrad, residing at 22442 Via Pajaro, Trabuco Canyon,
California 92679 ("Conrad").

         In consideration of the mutual covenants set forth in this Agreement,
the parties hereto agree as follows:

                                   ARTICLE 1.

                                  ORGANIZATION
                                  ------------

     Section 1.1. Formation of the Company. The Company was formed as a Delaware
limited liability company pursuant to the Act by the filing of the Certificate
of Formation on May 20, 2005. The rights and obligations of the Members shall be
as provided in the Act, except as otherwise expressly provided herein. The
Members shall from time to time execute or cause to be executed all such
certificates, instruments and other documents, and do or cause to be done all
such filings, recordings, publishings and other acts as the Board may deem
necessary or appropriate to comply with the requirements of law for the
operation of the Company in all jurisdictions in which the Company will conduct
business.

     Section 1.2. Name.

          (a) The business of the Company shall be conducted under the name
"PROVANSIS LLC An Inforte Company" or under such other name as the Board shall
determine.

          (b) In the event that Inforte ceases to be a Member of the Company,
the remaining Members, and the Board shall immediately cause the name "Inforte"
to be removed from the name of the Company. The Company shall immediately cease
to use the name "Inforte" in any manner, including, but not limited to (i)
advertising, (ii) branding, (iii) registering for any governmental or agency
permit, approval, or licensing, and (iv) entering into any agreement or
contract. The name of any products or services that were previously offered
under a name that included "Inforte" shall be changed so that the name does not
include "Inforte." The Company shall notify all of its then-existing clients
with respect to the Rx-Technology, Rx-Solutions, or any New Technology that: (i)
Inforte is no longer a Member of the Company and (ii) "Inforte" has been deleted
from the name of the Company.

<PAGE>

          (c) Each member acknowledges and agrees that the rights of Inforte
under Section 1.2(b) are of a specialized and unique character and that
immediate and irreparable damage will result to Inforte if the Company, the
Board, and the remaining Members fail to or refuse to perform their obligations
under this Section 1.2 and, notwithstanding any election by Inforte to claim
damages from the Company or any remaining Member as a result of any such failure
or refusal, Inforte may, in addition to any other remedies and damages
available, seek an injunction in a court of competent jurisdiction without the
posting of bond or other security to restrain any such failure or refusal. These
remedies are cumulative with all other remedies provided by law or contract, and
will not preclude Inforte from later obtaining a judgment for money damages or
specific acts against the Company or any remaining Member or otherwise affect
any other remedies that Inforte and its Affiliates may have. The exercise of any
right or remedy will be without prejudice to the right to exercise any other
right or remedy provided in this Agreement, by law or in equity.

     Section 1.3. Registered Office; Principal Place of Business. The address of
the registered office of the Company in the State of Delaware shall be the
address set forth in the Certificate of Formation, or such other place as may be
designated from time to time by the Board. The name of the registered agent for
service of process on the Company in the State of Delaware at such address shall
be as set forth in the Certificate of Formation or such other Person as may be
designated from time to time by the Board. The Company shall maintain a
principal place of business in such location as the Board shall determine. The
Board may change the registered agent or registered office, change the location
of the Company's principal place of business, or establish additional places of
business at such locations as the Board may from time to time determine in
compliance with the Act.

     Section 1.4. Purposes and Powers. The purposes of the Company are to
conduct any or all lawful business that a Delaware limited liability company is
or may be permitted to carry on. Subject to the terms and conditions of this
Agreement, the Company is authorized to enter into, make, and perform all
contracts and other undertakings, and engage in all other activities and
transactions, as the Board may deem necessary, advisable, or convenient for
carrying out the purposes of the Company.

     Section 1.5. Title to Property. Title to Company Assets shall be held in
the name of the Company.

     Section 1.6. Term. The Company commenced its existence upon the filing of
the Certificate and shall continue until it is dissolved in accordance with
Article 14 hereof.

                                   ARTICLE 2.

                              MEMBERSHIP INTERESTS

     Section 2.2 Issuance of Additional Units.

Members or to additional Persons on such terms and for such consideration as
shall be fixed by unanimous approval of the Board. Units may be issued from time
to time in one or more classes (in addition to the classes set forth in this
Agreement) or series, and each such class or series shall have such distinctive
designation or title as shall be fixed by the Board. Each such class or series
of Unit shall have such voting powers, full or limited, or no voting powers, and
such other relative rights, powers and preferences, including, without
limitation, the dividend rate, conversion rights, if any, redemption price and
liquidation preference, and such qualifications, limitations or restrictions,
thereof, as shall be stated in the resolution or resolutions providing for the
issuance of such class or series of Unit as may be adopted from time to time by
the Board. Each Person who subscribes for a Unit and satisfies the conditions
established by the Board shall be admitted to the Company as a Member, effective
upon the execution by such Person of a counterpart of this Agreement. The Board
shall have the power to adopt an amendment to this Agreement necessary to
implement the issuance of additional Units pursuant to this Section.

     Section 2.3 No Obligation to Make Additional Capital Contributions. No
Member shall be required by the terms of this Agreement to purchase additional
Units or otherwise make additional Capital Contributions to the Company.

dissolution and winding up of the Company.

                                   ARTICLE 3

                       AGREEMENTS REGARDING RX-TECHNOLOGY,
                  WORKING CAPITAL, AND ADMINISTRATIVE SERVICES
                  --------------------------------------------

     Section 3.1 Contribution of Exclusive Processing Services of Rx-Technology
in Term-Life Underwriting Application; First Right to Exclusive License.

          (a) The Company shall have the right, during the term of this
Agreement, to be the exclusive worldwide marketer of PKI's processing services
in connection with the underwriting of applications for term life insurance
using PKI's Rx-Technology pursuant to the terms and conditions of Exhibit B of
this Agreement; provided, however, that, if Inforte has not exercised both of
the Inforte Calls within the prescribed time periods set forth in Article 12,
the Company's right to be the exclusive marketer will thereupon automatically
become non-exclusive, but shall otherwise remain in full force and effect in
accordance with the terms and conditions of Exhibit B. PKI shall have the right,
during the term of this Agreement, to be the exclusive provider of processing
services to the Company and its customers in connection with the underwriting of
applications for term life insurance.


                                       3
<PAGE>

          (b) PKI promptly shall present or cause to be presented, on an
exclusive basis, to the Company, in writing, each New Technology using
prescription data made, conceived, or developed by PKI or one of its Affiliates
and which PKI or such Affiliate is not currently restricted from disclosing and
licensing to others under PRTLA, whereupon, if the Company chooses by written
notice within sixty (60) days of receipt of PKI's written presentation to
license such New Technology, the Company shall have an exclusive, fully paid-up,
royalty-free, worldwide license to such New Technology in accordance with the
terms of Exhibit B. Any such new technology that becomes subject to a license to
the Company is referred to herein as an Rx-Solution or Rx-Solutions. For
purposes of this Section, "New Technology" shall mean all concepts, inventions
(whether or not protected under patent laws), works of authorship, information
fixed in any tangible medium of expression (whether or not protected under
copyright laws), moral rights, mask works, trademarks, trade names, trade dress,
trade secrets, publicity rights, names, likenesses, know-how, ideas (whether or
not protected under trade secret laws), and all other subject matter protected
under patent (or which is not patented, but is subject matter that is protected
under patent law), copyright, mask work, trademark, trade secret, or other laws,
whether existing now or in the future, whether statutory or common law, in any
jurisdiction in the world, for all media now known or later developed, including
without limitation all new or useful art, combinations, discoveries, formulae,
algorithms, specifications, manufacturing techniques, technical developments,
systems, computer architecture, artwork, software, programming, applets,
scripts, designs, processes, and methods of doing business. All New Technology
that does not become an Rx-Solution or Rx-Solutions shall not be used or
disclosed by the Company or Inforte and all rights thereto shall be owned
exclusively by PKI.

     Section 3.2 Obligations to Fund Working Capital.

          (a) Upon the unanimous affirmative vote of the entire Board, Inforte
shall provide working capital in the form of unsecured loans to the Company (the
"Working Capital Advances"). The Working Capital Advances shall bear interest,
compounding monthly, at a per annum rate equal to the U.S. prime rate as
published in The Wall Street Journal and adjusted from time to time. The terms
and conditions of Inforte's obligation to provide Working Capital Advances are
set forth in Exhibit C to this Agreement.

          (b) Repayment by the Company of the outstanding balance of Working
Capital Advances and accrued interest thereon shall be paid monthly in an amount
equal to seventy percent (70%) of the Available Cash of the Company as of the
end of each month, and upon each such repayment, thirty percent (30%) of the
Available Cash shall be distributed to the Members. Notwithstanding any other
provision of this Agreement, so long as there remains outstanding any Working
Capital Advances, the Company shall make no distribution with respect to a
Member's Membership Interest in an amount in excess of thirty percent (30%) of
the Available Cash of the Company and then only after satisfaction of the
Company's obligation set forth in the immediately preceding sentence.

     Section 3.3 Inforte's Provision of Certain Services to the Company. At the
reasonable request of the Company, Inforte shall provide the Company accounting,
human resources, information technology and other related administrative
services. The Company shall promptly reimburse Inforte for all direct costs
incurred by Inforte in connection with providing such services plus twenty-five
percent (25%). The term "direct costs" for purposes of this Section 3.3


                                       4
<PAGE>


and Section 3.4 does not include indirect general and administrative costs,
depreciation, amortization, or other indirect accounting costs.

     Section 3.4 PKI's Provision of Certain Services to the Company. In addition
to the services contemplated by Exhibit B, at the reasonable request of the
Company, PKI shall provide the Company services supporting the marketing right
described in Section 3.1(a) and any license described in Section 3.1(b) and
other related services. The Company shall promptly reimburse PKI for all direct
costs incurred by PKI in connection with providing such services plus
twenty-five percent (25%).

     Section 3.5 New Technology Developed by Inforte. Inforte promptly shall
present or cause to be presented, on an exclusive basis, to the Company, in
writing, each New Technology using prescription data, made, conceived, or
developed by Inforte or one of its Affiliates, whereupon, if the Company chooses
by written notice within sixty (60) days of receipt of Inforte's presentation to
license such New Technology, the Company shall have an exclusive, fully paid-up,
royalty-free, worldwide license to such New Technology. All such New Technology
that is not licensed to the Company shall not be used or disclosed by the
Company or PKI and all rights thereto shall be owned exclusively by Inforte. The
foregoing obligation of Inforte to present New Technology to the Company shall
not apply to any New Technology that is made, conceived, or developed (i) by
Inforte, jointly with a client or (ii) by Inforte for a client.

                                   ARTICLE 4

                  NON-COMPETITION CONDITIONS ON PKI AND CONRAD
                  --------------------------------------------

     Section 4.1 Rx-Technology. Until the later of (i) the fifth anniversary of
the date on which this Agreement is executed or (ii) one year after PKI ceases
to be a Member for any reason, neither PKI, Conrad nor any of their respective
Affiliates, directly or indirectly, shall either (a) provide or offer or attempt
to provide or offer, whether as an officer, director, employee, partner,
consultant, licensor, shareholder, independent contractor, or otherwise any
Rx-Technology or Rx-Solutions to any Person other than the Company anywhere in
the world, or (b) become an officer, director, partner, owner, or employee of,
or contractor with or consultant to, or invest in, any Person which engages in
activities described in clause (a); provided, however, that, if the Company's
license to use the Rx-Technology becomes non-exclusive pursuant to Section
3.1(a), this covenant not to compete shall be limited to the extent necessary to
allow PKI to use or license the Rx-Technology to the extent of such
non-exclusivity; provided further, however, the parties hereto acknowledge that,
subject to Section 15.3(c), PKI may become a member of Predictive Data LLC
("Predictive Data"), which is in formation, and that Predictive Data, similar to
the Company, also may market processing services using Rx-Technology, in which
event Predictive Data will contract with the Company on terms mutually agreeable
to PKI and Inforte to enable it to provide such services.

     Section 4.2 No Employee Solicitation. Until two years after PKI ceases to
be a Member for any reason, neither PKI, Conrad nor any of their respective
Affiliates, directly or indirectly, shall induce or attempt to induce any
officer or employee of or consultant to the Company to terminate his or her
employment or consultancy with the Company.



                                       5
<PAGE>

     Section 4.3 Restrictions Reasonable. PKI and Conrad each acknowledges and
agrees that the restrictions and other provisions set forth above in this
Article 4 are reasonable, in all respects, including, without limitation,
duration, geographic reach, and scope of activities covered, and will not
prevent Conrad from earning a living in his profession. Further, PKI and Conrad
each acknowledges that in agreeing to said restrictions, it or he has received
and has relied upon the independent advice and counsel of attorneys selected by
it or him. Accordingly, PKI and Conrad each agrees to be bound by and to
faithfully observe the restrictions and covenants set forth above in this
Article 4, and further agrees that it or he will not do or attempt to do
indirectly, through any other Person, or by any other manner, means, or
artifice, anything which this Article 4 prohibits it or him from doing directly.

     Section 4.4 Remedies.

     PKI and Conrad each acknowledges and agrees that the rights of the Company
under this Agreement are of a specialized and unique character and that
immediate and irreparable damage will result to the Company if either PKI or
Conrad fails to or refuses to perform his obligations under this Article 4 and,
notwithstanding any election by the Company to claim damages from PKI or Conrad
as a result of any such failure or refusal, the Company may, in addition to any
other remedies and damages available, seek an injunction in a court of competent
jurisdiction without the posting of bond or other security to restrain any such
failure or refusal. These remedies are cumulative with all other remedies
provided by law or contract, and will not preclude the Company from later

     Section 5.1 Distributions.

          (a) Subject to the limitation of Section 3.2(b), to the extent
permitted by law, the Board shall from time to time, as described in Section

respective Units.

          (b) Capital Transaction Proceeds shall be distributed to the Members
as soon as reasonably practicable after the completion of a Capital Transaction.
All such distributions shall be made in the following order of priority:

                    (i) First, such Capital Transaction Proceeds shall be made
          to Members in proportion to their respective Unreturned Capital, until
          the Unreturned Capital of each Member has been reduced to zero;

                    (ii) Second, the remaining Capital Transaction Proceeds
          shall be distributed 100% to Meyer, until he has received aggregate
          distributions under this Section 5.1(b)(ii) equal to the product of

          distributions under subparagraph (i) of this Section 5.1(b),
          multiplied by (B) a fraction, the numerator of which is the number of
          Units held by Meyer, and the denominator of which is the number of
          Units held by Members receiving distributions under said subparagraph
          (i); and

                    (iii) Third, the remaining Capital Transaction Proceeds
          shall be distributed to the Members in proportion to their respective

     Section 6.1 Initial Capital Contribution.

          (a) Within thirty (30) days of the date of formation of the Company
under the Act, or on such later dates as the Members holding, in the aggregate,
at least eighty-five percent (85%) of the then outstanding Units shall agree in
writing, each Member shall make an initial Capital Contribution to the Company
in cash or property as set forth below:

                    (i) Inforte shall contribute Two-Million Dollars
          ($2,000,000.00) in cash.

                    (ii) PKI shall contribute (a) the right to exclusively
          market PKI's processing services using Rx-Technology as described in
          Section 3.1(a) and (b) the right to license Rx-Solutions as described
          in Section 3.1(b), which, for purposes of Section 6.2(a)(i) and (ii)
          shall be valued at $7,450,980.

          (b) Notwithstanding any other provision of this Agreement, upon the
receipt of Inforte's and PKI's initial respective Capital Contributions, the
Company shall make a special cash distribution in the amount of Two-Million
Dollars ($2,000,000.00) to PKI. Notwithstanding that the transfer of PKI's
rights pursuant to Section 6.1(a)(ii) is treated as a Capital Contribution for
purposes of this Agreement, and the special cash distribution under the
immediately preceding sentence is treated as a distribution for purposes of this
Agreement, the parties acknowledge that the transactions shall be treated as a
purchase of assets from PKI for federal income tax purposes to the extent of the
amount of the special distribution.

          (c) Upon the admission of a new Member in accordance with Section 2.2,
or on such later dates as PKI and Inforte, from time to time, shall agree in
writing, each new Member shall make a Capital Contribution to the Company in
such amount and in such form as the Board shall decide.

<PAGE>


          (a) A Capital Account shall be maintained for each Member in
accordance with the requirements of Section 704(b) of the Code and the
Regulations promulgated thereunder. The Capital Account balance of each Member
shall be adjusted as follows:

                    (i) increased by any Capital Contributions made by such
          Member;

                    (ii) increased by items of income or gain which are
          allocated to such Member under this Article 6;

                    (iii) decreased by the items of loss and deduction which are
          allocated to the Member under this Article 6; and

                    (iv) decreased by the amount of any cash and the fair market
          value of any Company Asset distributed to such Member (net of any
          liability assumed by the Member or to which the distributed property
          is subject).

          (b) If a Company Asset other than cash is distributed to one or more
Members, the value of such property shall be restated on the books of the
Company at its fair market value immediately prior to such distribution and the
separate Capital Accounts of each Member shall be restated to reflect such
adjustment, determined as if the Company had sold such Company Asset for its
fair market value and the resulting gain or loss had been credited or charged to
the Members' Capital Accounts as provided in this Agreement. Following such
adjustment to the Company's books, the separate Capital Accounts of the Members
receiving the distributions shall be adjusted to reflect the amount of the
distribution.

          (c) If a Person is admitted to the Company as an additional Member,
money or property is contributed to the Company in other than a de minimis
amount in exchange for a Membership Interest, or money or property is
distributed to a Member in exchange for a Membership Interest, the Company may
cause the book value of Company Assets to be restated on the Company's books to
their respective fair market values, and the unrealized gain or loss inherent in
each Company Asset which has not previously been taken into account under this
subsection (c) shall be reflected in the separate Capital Accounts of the
Members, determined by allocating such unrealized income, gain, loss, or
deduction to the Members as if there had been a taxable disposition of the
Company Asset at its fair market value on such date. The fair market value of
Company Assets shall be determined in good faith by the Board. No restatement of
the Capital Accounts shall be made in connection with the Contributions to the
Company by PKI or Inforte.

          (d) Upon a transfer of any Membership Interest in accordance with the
terms of this Agreement, the Assignee shall succeed to the Capital Account of
the transferor which is attributable to such Membership Interest.

          (e) The foregoing provisions and the other provisions of this
Agreement relating to the maintenance of Capital Accounts are intended to comply
with ss. 1.704-1(b) of the Regulations promulgated under section 704(b) of the
Code. The Board shall apply said provisions in a manner consistent with said
Regulations.

     Section 6.3 Periodic Allocations. As of the end of each Fiscal Year of the
Company, the Net Loss or Net Profit of the Company for the Fiscal Year shall be
determined and allocated among the Members in accordance with this Article 6.

          (a) Except as provided in subsection (c) or Section 6.4, the Net
Profit for a Fiscal Year shall be allocated among the Members in the following
order of priorities:

                    (i) First, if any Member has an Adjusted Capital Account
          deficit balance, Net Profit shall be allocated to such Members to the
          extent of, and in proportion to, the amount required to eliminate the
          deficit Adjusted Capital Account balances of all such Members;

                    (ii) Second, the remaining Net Profit shall be allocated to
          the Members who have Unreturned Capital, to the extent of and in
          proportion to the amount required to increase each Member's Adjusted
          Capital Account balance to an amount equal to its Unreturned Capital;
          and

                    (iii) The remaining Net Profit for the Fiscal Year, if any,
          shall be allocated among the Holders of Units in proportion to the
          number of Units held by them.

          (b) Except as provided in subsection (c) or Section 6.4, the Net Loss
for a Fiscal Year shall be allocated among the Members in the following order of
priorities:

                    (i) First, such Net Loss shall be allocated among the
          Holders of Units in proportion to the amount by which the Holders of
          Units' respective Adjusted Capital Account balances exceed their
          Unreturned Capital until the amount of such excess has been reduced to
          zero;

                    (ii) Second, Net Loss shall be allocated among the Holders
          of the Units in proportion to their respective positive Capital
          Accounts balances, until each such Capital Account has been reduced to
          zero; and

                    (iii) The remaining Net Loss for the Fiscal Year shall be
          allocated among the Holders of Units in proportion to their respective
          Units.

          (c) Notwithstanding the foregoing, gain or loss from a Capital
Transaction shall be allocated among the Members in such proportions and amounts
as are required to cause the Capital Account of each Member to equal the amount
of Capital Transaction Proceeds from such Capital Transaction which such Member
is entitled to receive pursuant to Section 5.1(b).

     Section 6.4 Tax Allocations.

          (a) The allocations set forth in this Article 6 are intended to
allocate Net Profits and Net Losses to the Members in compliance with the
requirements of section 704(b) of the Code and the Treasury Regulations
promulgated thereunder. If the Board reasonably and in good faith determines
that the allocation of items of Company income, gain, loss, deduction, and
credit pursuant to this Section 6.4(a) does not satisfy the requirements of
section 704(b) of the Code or the Treasury Regulations thereunder (including the
minimum gain chargeback requirement of ss. 1.704-2 of the Treasury Regulations
and the qualified income offset requirement of ss. 1.704-1(b)(2)(iv)(d) of the
Treasury Regulations), then notwithstanding anything to the contrary contained
in this Agreement, such items of income, gain, loss, deduction or credit shall
be allocated in such manner as the Board shall reasonably and in good faith
determine to be required by section 704(b) of the Code and the Treasury
Regulations promulgated thereunder. To the extent that the Board alters the
allocations pursuant to this subsection (a), the Company shall make such
offsetting special allocations of Company income, gain, loss or deduction for
the fiscal year or subsequent fiscal years as it determines appropriate so that,
after such offsetting allocations are made, each Member's Capital Account
balance is, to the extent possible, equal to the Capital Account balance such
Member would have had if the Board had not made the allocations under this
Section 6.4(a) and all Company items were allocated pursuant to Section 6.3
hereof.

          (b) Solely for federal, state, and local income tax purposes and not
for book or Capital Account purposes, except to the extent required by
Regulations, depreciation, amortization, gain, or loss with respect to property
that is properly reflected on the Company's books at a value that differs from
its adjusted basis for federal income tax purposes shall be allocated in
accordance with the principles and requirements of Code Section 704(c) and the
Regulations promulgated thereunder, and in accordance with the requirements of
the relevant provisions of the Regulations issued under Code Section 704(b). For
Capital Account purposes, depreciation, amortization, gain, or loss with respect
to property that is properly reflected on the Company's books at a value that
differs from its adjusted basis for tax purposes shall be determined in
accordance with the rules of Regulation Section 1.704-1(b)(2)(iv)(g).

          (c) The Members are aware of the income tax consequences of the
allocations made by this Section 6 and hereby agree to be bound by the
provisions of this Section 6 in reporting their shares of Company income and
loss for income tax purposes. Each Member further agrees that it will not take
any position with respect to any Company item in any tax return, refund claim,
or other document filed with any tax authority, or on an audit of the Company's
tax returns, that is inconsistent with the positions taken by the Company on its
tax returns.

     Section 6.5 Changes in Members' Interests. If during any fiscal period of
the Company there is a change in any Member's Membership Interest as a result of
the admission of one or more Members, the withdrawal of a Member, or a transfer
of a Membership Interest that does not result in the termination of the Company
for federal income tax purposes, the Net Profit, Net Loss or any other item
allocable to the Members under this Article 6 for the period shall be allocated
among the Members so as to reflect their varying interests in the Company during
the period. In the event that the change in the interests of the Members results
from the admission or



                                       10
<PAGE>

withdrawal of a Member, the allocation of Net Profit, Net Loss, or any other
item allocable among the Members under this Article 6 shall be made on the basis
of an interim closing of the Company's books as of each date on which a Member
is admitted to or withdraws from the Company. In the event that the change in
the Membership Interests of the Members results from a transfer of all or any
portion of a Membership Interest by a Member, the Net Profit, Net Loss, or any
other items allocable among the Members under this Article 6 shall be determined
on a daily, monthly, or other basis, as determined by the Members using any
permissible method under Section 706 of the Code and the Treasury Regulations
promulgated thereunder.

Company for all purposes pursuant to Sections 6221-6231 of the Code; provided,
however, that if Inforte fails to exercise both of the Inforte Calls within the

Permitted; Vote Required for Action. Presence of a majority of the authorized
number of Managers at a meeting of the Board constitutes a quorum for the
transaction of business, except as hereinafter provided. Managers may
participate in a meeting through use of conference telephone or similar
communications equipment, so long as all Managers participating in such meeting
can communicate with and hear one another. Except where otherwise provided in
this Agreement, every act or decision done or made by a majority of the Managers
present at a meeting duly held at which a quorum is present shall be regarded as
the act of the Board, unless there are only two Managers in which case unanimity
shall be required. A meeting at which a quorum is initially present may continue
to transact business notwithstanding the withdrawal of Managers, provided that
any action taken is approved by at least a majority of the required quorum for
such meeting. A majority of the Managers present, whether or not a quorum is
present, may adjourn any meeting to another time and place. If a meeting is
adjourned for more than twenty-four (24) hours, notice of any adjournment to
another time or place (other than adjournments until the time fixed for the next

prior to the time of the adjourned meeting to the Managers who were not present

force and effect as a unanimous vote of the Board.

of Formation and Section 8.2 of this Agreement, the Board may determine from
time to time to appoint one or more individuals as officers of the Company. An
officer need not be a Member or Manager of the Company, and any number of
offices may be held by the same person. The officers of the Company initially
shall be a Chief Executive Officer and Secretary. The Company may also have, at
the discretion of the Board, such other officers as may be designated from time
to time by the Board.

     Section 9.2 Appointment and Removal. The officers shall be appointed by the
Board, subject to Section 8.2. Each officer, including an officer elected to
fill a vacancy, shall hold office at the pleasure of the Board until his or her
successor is elected, except as otherwise provided by the Act. Any officer may
be removed, with or without cause, at any time by the affirmative vote of a
majority of the Managers then in office, unless there are only two Managers in
which case unanimity shall be required.

     Section 9.3 Chief Executive Officer - Rights, Duties, and Powers. The Chief
Executive Officer shall be the chief executive officer of the Company and,
subject to the authority of the Board, shall in general supervise and control
all of the business and affairs of the Company. He may sign any contracts or
other instruments which the Board has authorized to be executed and in general
shall perform all duties incident to the office of Chief Executive Officer and
such other duties as may be prescribed by the Board from time to time.

     Section 9.4 Resignation of a CEO. At any time upon at least ten (10) days'
prior written notice to the Members, a CEO may resign such position, whereupon,
subject to Section 8.2, the Board shall designate another Person to be a
successor CEO. Neither acceptance by the Members of such resignation, nor
selection of a successor CEO, shall be necessary to make such resignation
effective. If the CEO is also a Member, such resignation shall not affect such
CEO's rights or liabilities as a Member except to the extent expressly otherwise
provided in this Agreement.

     Section 9.5 Authority to Designate Officers. Subject to Section 8.2, the
Board may elect or designate, by resolution or otherwise, individuals as
officers of the Company and revocably delegate to such officers such powers,
authority, and responsibilities of the CEO as are (i) set forth in the
designation or delegation and (ii) necessary to carry out and implement the
management decisions of the Board. The Board may remove any officer, including
the CEO, with or without cause, at any time. Any officer may resign at any time
by giving written notice to the Company. Any resignation shall take effect at
the date of the receipt of such notice or at any later time specified in such
notice (unless such officer is otherwise removed prior to such date); and unless
otherwise specified in such notice, the acceptance of the resignation shall not
be necessary to make it effective. Any removal or resignation is without
prejudice to the rights, if any, of the Company or the officer under any
contract of employment with the Company.

     Section 9.6 Limited Liability. To the fullest extent permitted under
applicable law, no Member, CEO, officer, or shareholder, manager, member,
officer, employee, trustee or agent of a Member, shall be deemed to violate this
Agreement or be liable, responsible or accountable in damages or otherwise to
any Member or the Company for any action or failure to act, unless such
violation or liability is attributable to such Person's gross negligence,
willful misconduct, bad faith or a material breach of this Agreement. Without
limiting the generality of the foregoing, each such Person shall, in the
performance of his, her or its duties, be fully protected in relying in good
faith upon the records of the Company and upon information, opinions, reports or
statements presented to such Person by the Board, the Members or by any other
Person as to matters such Person reasonably believes are within such other
Person's professional or expert competence and who has been selected with
reasonable care by or on behalf of the Company, the Board or the Members.

     Section 9.7 Indemnification. To the fullest extent permitted under
applicable law, the Company shall indemnify and hold harmless any Person (an
"Indemnified Party") who was or is a party, or is threatened to be made a party,
to any threatened, pending or completed action, suit or proceeding, whether
civil, criminal, administrative or investigative (including any action by or in
the right of the Company) by reason of or arising from any acts or omissions (or
alleged acts or omissions) on behalf of the Company or in furtherance of the
interests of the Company arising out of the Indemnified Party's activities as a
Member, CEO or officer of the Company, or as an officer, director, shareholder,
member, manager, employee, trustee or agent of said Member, against losses,
damages or expenses (including reasonable attorneys' fees, judgments, fines and
amounts paid in any action, suit or proceeding and for which such Indemnified
Party has not otherwise been reimbursed and further including reimbursement of
fees and costs reasonably incurred by any Indemnified Party to enforce the
provisions of this Section 9.7), so long as such Indemnified Party did not act
in bad faith or in a manner constituting gross negligence, willful misconduct or
a material breach this Agreement. The termination of any action, suit or
proceeding by judgment, order, settlement or upon a plea of nolo contendere or
its equivalent shall not of itself (except insofar as such judgment, order,
settlement or plea shall itself specifically provide) create a presumption that
the Indemnified Party acted in bad faith or in a manner constituting gross
negligence, willful misconduct or a material breach of this Agreement.

     Section 9.8 Affiliated Transactions. Other than pursuant to the terms and
conditions of Exhibits B and C, the Company shall not enter into or maintain any
transaction or agreement with any of its Affiliates, except in the ordinary
course of business and upon fair and reasonable terms no less favorable to the
Company than would be obtained by the Company in a comparable arm's length
transaction with a Person who is not the Company's Affiliate.

                            RESTRICTIONS ON TRANSFER
                            ------------------------

     Section 11.1 PKI Restriction on Transfer. PKI shall be prohibited from
Transferring Units held by it until the first anniversary of the date of this
Agreement, after which any Transfer of Units shall remain subject to other
restrictions on Transfer of Units set forth in this Agreement.

     Section 11.2 Company Right of First Offer.

          (a) Except for Transfers permitted by Section 11.4, if a Holder
desires to Transfer any Units or other securities convertible into or
exercisable for Units (collectively, the "Offered Securities"), such Holder (the
"Selling Holder") will first give written notice (the "Offer Notice") to the
Company and each non-Selling Holder holding at least ten percent (10%) of the
outstanding Units (collectively, the "Qualified Non-Selling Holders") stating
the purchase price, the number and type of Offered Securities, and other
material terms and conditions upon which such Offered Securities are to be
offered for sale and making an offer to sell such Offered Securities (the
"Offer") first to the Company and then to the Qualified Non-Selling Holders
pursuant to the terms and conditions of this Section, at the price and on the
other terms described in the Offer Notice. The date upon which the Offer Notice
is given to the Company and the Qualified Non-Selling Holders is called the
"Offer Notice Date."



                                       22
<PAGE>

          (b) The Company may elect to purchase Offered Securities by giving
written notice thereof (the "Company's Acceptance Notice") to the Selling Holder
(and if the Company does not elect to purchase all of the Offered Securities,
also to the Qualified Non-Selling Holders) within twenty (20) days following the
Offer Notice Date setting forth the number of Offered Securities the Company is
willing to purchase. In the event the Offer has been accepted in its entirety by
the Company, the Selling Holder shall sell the Offered Securities to the Company
on the terms and conditions set forth in the Offer Notice and the closing shall
take place within ninety (90) days after the Offer Notice Date, unless a later
date is agreed to by the parties.

          (c) In the event that the Company does not elect to purchase all of
the Offered Securities, each Qualified Non-Selling Holder may elect to purchase
remaining Offered Securities by giving written notice thereof (the "Holders'
Acceptance Notices") to the Selling Holder within ten (10) days following the
Company's Acceptance Notice setting forth the maximum number of Offered
Securities such Qualified Non-Selling Holder is willing to purchase. In the
event that the Holders' Acceptance Notices in the aggregate contain offers to
purchase more than the number of Offered Securities available, the Qualified
Non-Selling Holders shall be entitled to purchase such Offered Securities pro
rata among themselves on the basis of the number of Units held by each such
Qualified Non-Selling Holder. In the event the Offer has been accepted in its
entirety by the Company and Qualified Non-Selling Holders, the Selling Holder
shall sell the Offered Securities to the Company and the Qualified Non-Selling
Holders on the terms and conditions set forth in the Offer Notice and the
closing shall take place within ninety (90) days after the Offer Notice Date,
unless a later date is agreed to by the parties.

          (d) In the event the Offer has not been accepted in its entirety by
the Company and/or the Qualified Non-Selling Holders, the Selling Holder shall
not be obligated to sell any Offered Securities to the Company or the Qualified
Non-Selling Holders, and the Selling Holder may, within 120 days after the Offer
Notice Date, sell the Offered Securities to a purchaser(s) who agrees in writing
to be bound by the terms of this Agreement to the same extent as the Selling
Holder, provided such sale is on terms no more favorable to such purchaser(s)
than those stated in the Offer Notice. If such sale has not been completed
within such 120-day period, such sale may not be carried out without complying
again with the provisions of this Section.

          (e) Notwithstanding the foregoing, the provisions of this Section 11.2
shall not apply to (i) sales of all of the outstanding Units in the Company,
(ii) any sale of all the outstanding Units held by both PKI and Inforte; or
(iii) any sale by a Member to the Company pursuant to this Agreement.

     Section 11.3 Co-Sale Rights.

          (a) In the event that, after complying with the terms of Section 11.2
if applicable, a Selling Holder desires to sell to a third party, in one
transaction or a series of related transactions, Units representing ten percent
(10%) or more of the issued and outstanding Units (such third party, the
"Proposed Purchaser", such transfer, the "Proposed Transfer", and such Units to
be purchased, the "Transferred Securities"), then such Selling Holder's right to
accept any offer shall be conditioned upon Qualified Non-Selling Holders being
offered the right to sell to the Proposed Purchaser their "proportionate number"
of the Transferred Securities. A


                                       23
<PAGE>


Qualified Non-Selling Holder's "proportionate number" of the Transferred
Securities shall be determined by multiplying the Units represented by the
Transferred Securities by a fraction, (x) the numerator of which is the number
of Units held by such Qualified Non-Selling Holder and (y) the denominator of
which is the total number of outstanding Units. The Transferred Securities to be
purchased from any Qualified Non-Selling Holder pursuant to this Section 11.3
shall be paid and contracted for at the same price per Unit, with the same form
of consideration and otherwise upon the same terms and conditions as the sale by
the Selling Holder of its Units to the Proposed Purchaser.

          (b) A Selling Holder shall, not less than thirty (30) days prior to
each Proposed Transfer it intends to effect, notify Qualified Non-Selling
Holders in writing of such Proposed Transfer (the "Participation Notice"). Such
Participation Notice shall set forth: (i) the number and type of Transferred
Securities; (ii) the name(s) and address(es) of the Proposed Purchaser(s); (iii)
the proposed amount and all forms of consideration and terms and conditions of
payment offered by such Proposed Purchaser, including the proposed date for the
closing of the Proposed Transfer (the "Scheduled Closing"); and (iv) that the
Proposed Purchaser has been informed of the co-sale rights of Qualified
Non-Selling Holders provided for in this Section 11.3 and has agreed to purchase
the Transferred Securities in accordance with the terms hereof.

          (c) The co-sale rights described in this Section 11.3 may be exercised
by a Qualified Non-Selling Holder's delivery of a written notice to the Selling
Holder (the "Exercise Notice") at least ten (10) days prior to the Scheduled
Closing or within twenty (20) days after delivery of the Participation Notice,
whichever occurs first. Such notice shall state the number of Units (including
the type of units) the Qualified Non-Selling Holder elects to include in such
sale to the Proposed Purchaser. If the Qualified Non-Selling Holder fails to
timely provide an Exercise Notice, such failure shall be regarded as an election
by the Qualified Non-Selling Holder not to participate in the Proposed Transfer.
In addition, if the Qualified Non-Selling Holder fails to elect to sell its full
"proportionate amount", the amount the Qualified Non-Selling Holder fails to
sell may be sold by the Selling Holder to the Proposed Transferee.

          (d) In the event that PKI or Inforte exercises its co-sale rights
pursuant to this Section 11.3 and the Proposed Purchaser is not willing to
purchase Units from the Qualified Non-Selling Holder on the same terms and
conditions as specified in the Participation Notice, then the Selling Holder
shall not be permitted to sell any Units to the Proposed Purchaser pursuant to
the Proposed Transfer.

     Section 11.4 Permitted and Involuntary Transfers. Notwithstanding anything
herein to the contrary, the Holders may Transfer Units and other securities
convertible or exercisable for Units free of the restrictions contained in this
Article 11: (a) subject to Section 11.1, if the Holder is a natural person, by

                            ------------------------

     Section 12.1 Inforte First Call. Effective as of the date of this
Agreement, Inforte shall have the option (the "Inforte First Call") to purchase
a whole number of Units (the "Inforte First Call Units") from PKI that is

thirty-five percent (35%) of all outstanding Units on a fully diluted basis. The
exercise price shall be One Million Dollars ($1,000,000.00) (the "Inforte First
Call Price"). Inforte may exercise the Inforte First Call by giving notice (the
"Inforte First Call Notice") in writing to PKI within the time restrictions set
forth in Section 12.3 below, stating its intention to exercise such call. The
day on which the Inforte First Call Notice is given is the "Inforte First Call
Notice Date." Within thirty (30) business days from the Inforte First Call
Notice Date, unless a later date is agreed to by the parties, PKI shall sell,
and Inforte shall purchase, the Inforte First Call Units, free and clear of all
security interests, liens and encumbrances. Simultaneous with the conveyance of
the Inforte First Call Units, Inforte shall pay to PKI the Inforte First Call
Price. Such payment shall be made by wire transfer, or such other form as
Inforte and PKI mutually agree. Upon the completion of the transfer of the
Inforte First Call Units permitted by this Section 12.1, PKI shall be deemed to
have transferred to Inforte an amount of its Unreturned Capital and Capital
Account equal to the purchase price paid by Inforte.

     Section 12.2 Inforte Second Call. Provided that Inforte exercises the
Inforte First Call, effective as of the date of this Agreement, Inforte shall
have the option (the "Inforte Second Call" and, with the Inforte First Call,
collectively, the "Inforte Calls") to purchase a whole


                                       25

(51%) of all outstanding Units on a fully diluted basis. The exercise price for
the Inforte Second Call shall be One Million Dollars ($1,000,000.00) (the
"Inforte Second Call Price"). Inforte may exercise the Inforte Second Call by
giving notice (the "Inforte Second Call Notice") in writing to PKI within the
time restrictions set forth in Section 12.3 below, stating its intention to
exercise such call. The day on which the Inforte Second Call Notice is given is
the "Inforte Second Call Notice Date." Within thirty (30) business days from the
Inforte Second Call Notice Date, unless a later date is agreed to by the
parties, PKI shall sell, and Inforte shall purchase, the Inforte Second Call
Units, free and clear of all security interests, liens and encumbrances.
Simultaneous with the conveyance of the Inforte Second Call Units, Inforte shall
pay to PKI the Inforte Second Call Price. Such payment shall be made by wire
transfer, or such other form as Inforte and PKI mutually agree. Inforte shall
not exercise the Inforte Second Call prior to exercise of the Inforte First Call
but may exercise both calls simultaneously. Upon the completion of the transfer
of the Inforte Second Call Units permitted by this Section 12.2, PKI shall be
deemed to have transferred to Inforte an amount of its Unreturned Capital and
Capital Account equal to the purchase price paid by Inforte.

     Section 12.3 Termination of the Inforte Calls. The Inforte First Call may
be exercised until November 21, 2005 (the "Inforte First Call Termination

Termination Date" and, with the Inforte First Call Termination Date,
collectively, the "Inforte Call Termination Dates").

     Section 13.1 PKI Call.

          (a) In the event that Inforte fails to exercise either of the Inforte
Calls prior to the Inforte Call Termination Dates, then PKI shall have the right
to purchase all, but not less than all, of the Units held by Inforte (the "PKI
Call"). The PKI Call shall expire on the date (the "PKI Call Termination Date")
that is twenty (20) business days after the Inforte Second Call Termination
Date. The exercise price of the PKI Call (the "PKI Call Price") shall be the sum
of (i) to the extent paid by Inforte, the Inforte First Call Price plus (ii) the
greater of Two Million Dollars ($2,000,000.00) or the amount of Inforte's
Capital Account balance at the time the full PKI Call Price is tendered.

          (b) As a condition to closing of the PKI Call, PKI shall repay any
outstanding Working Capital Advances prior to or contemporaneous with the

     Section 13.2 Deferred Closing of PKI Call.

          (a) PKI shall tender the entire PKI Call Price to Inforte not later
than the one-year anniversary of the date on which PKI delivered the PKI Call
Notice. Such payment shall be made by wire transfer, or such other form as
Inforte and PKI mutually agree. As soon as practicable after receipt of the PKI
Call Price, Inforte shall transfer all of its Units to PKI.

          (b) Until such time as the full PKI Call Price is delivered to
Inforte, Inforte shall remain the owner of the Units covered by the PKI Call,
and shall remain a Member, with all of the rights entitled to it as a Member. If
PKI has exercised the PKI Call but the closing of the PKI Call does not occur on
or before the first anniversary date of the PKI Call Notice, the PKI Call and
all rights and obligations of PKI under this Article 13 thereupon automatically
shall terminate.

          (c) From the date of the PKI Call Notice until and including the date
on which the full PKI Call Price is tendered, any outstanding balance of the PKI
Call Price shall bear interest, compounding, monthly at per annum rate equal to
the U.S. prime rate reported in The Wall Street Journal, as adjusted from time
to time, as of the first business day in each calendar month that a balance is
outstanding.

          (c) Any other event which, under the Act, requires the dissolution of
the Company and the winding up of its business and affairs.

         Dissolution of the Company shall be effective on the date on which the

winding up of the Company and the filing of Articles of Dissolution.

liquidating trustee and wind up the affairs of the Company in the following
manner:


                                       27
<PAGE>

          (a) The liquidating trustee shall use commercially reasonable best
efforts to sell all of the Company's assets in an orderly manner (so as to avoid
the loss normally associated with forced sales).

          (b) The liquidating trustee shall apply and distribute the proceeds of
all such sales, together with other assets which the liquidating trustee was
unable to dispose of in accordance with paragraph (a), in the following order of
priority: (A) first, to the payment of any Working Capital Advances, (B) second,
to the payment of all other debts and liabilities of the Company (including
debts and liabilities owed to Members); (C) third, to the establishment of any
reserves reasonably necessary to provide for any contingent Company liabilities
and obligations (such reserves to be paid over to a bank or trust company, as
escrowee, to be held by such escrowee for the purpose of disbursing such
reserves in payment of any such contingent liability or obligation and to pay
over the balance thereafter remaining for distribution in the manner set forth
in clause (D) hereof); and (D) fourth, to the distribution of the Members in
accordance with Section 5.1(b).

     Section 14.3 Termination. Each of the Members will be furnished with a
statement prepared by the Accountant, which will set forth the assets and
liabilities of the Company as of the date of the final distribution of Company
Assets under Section 14.2 and the Net Profits or Net Losses and other items
allocable under Article 7 of this Agreement for the fiscal period ending on such
date. Upon compliance with the distribution plan set forth in Section 14.2, the
Members will cease to be such, and the liquidating trustee will cause a
certificate of dissolution to be filed, whereupon the Company will terminate.

     Section 14.4 Deemed Liquidation.

          (a) Upon a Fundamental Change or Change of Control (each as defined
below), Inforte may, in its sole discretion, by written notice to the Company,
elect to treat such transaction as a deemed liquidation if Inforte has not
otherwise participated in such transaction in accordance with any other
applicable purchase and/or co-sale rights afforded Inforte in Article 12 above.
Within ninety (90) days of receipt of such notice from Inforte, the Company
shall pay to Inforte, in exchange for the redemption of Inforte's Units, an
amount equal to the amount Inforte would have received on account of its Units
in a true liquidation pursuant to Section 14.2 if all assets of the Company had
been sold for cash equal to the fair market value of such assets.

          (b) For purposes of this Section 14.4, "Fundamental Change" shall mean
a reorganization, consolidation or merger in which the Company is a party except
any reorganization, consolidation or merger where, after giving effect thereto,
the Members of the Company immediately prior to such transaction (on a fully
diluted basis) will own immediately following such transaction equity interests
in the surviving entity possessing the voting power under ordinary circumstances
to control the business and affairs of the surviving entity, or a sale or other
transfer of all or substantially all of the assets of the Company in any
transaction or series of related transactions (other than sales in the ordinary
course of business); the term "Change of Control" shall mean any sale, transfer,
issuance or redemption or series of sales, transfers, issuances or redemptions
(or any combination thereof) of (i) the Company's Membership Interests (on



                                       28
<PAGE>

a fully diluted basis) by the Holders thereof or the Company which results in
any Person or group of affiliated Persons (other than the Members of the Company
(on a fully diluted basis) as of immediately prior to any such transaction or
series of transactions) owning Membership Interests in the Company possessing
the voting power under ordinary circumstances to control the business and
affairs of the Company or (ii) PKI's voting securities (on a fully diluted
basis) by the holders thereof which results in any Person or group of affiliated
Persons (other than the Conrad or persons in his immediate family) owning
securities possessing the voting power under ordinary circumstances to control
the business and affairs of PKI.

     Section 15.3 Covenants.

          (a) Preservation of Business. PKI shall take such action as may be
necessary to maintain, preserve, renew and keep in favor and effect the
existence and rights of PKI and its assets and will preserve the business
organization of PKI intact.

          (b) Maintenance of Rights to Use Rx-Technology. PKI and Conrad shall
not take, or fail to take, any action, including, but not limited to, (i)
entering into or withdrawing from any agreement, contract, instrument, indenture

license, authorization, or approval applicable to PKI; and (v) initiating or
joining any claim, suit, arbitration, mediation, or any such proceeding to
determine the legal rights of any Person, if such action or failure to act
constitutes a contradiction, violation, or breach of any provision of the PRTLA
and causes PKI or the Company, with or without, the passage of time, giving of
notice, or action by any other Person, to lose or diminish any rights to the
Rx-Technology granted or maintained under the PRTLA. Without limiting the
generality of the foregoing sentence, PKI shall not (i) attempt to sell,

Rx-Technology; or (ii) attempt to sell, transfer, assign, sublicense, or
otherwise convey substantially all of its assets; and Conrad shall not sell,
transfer, assign, sublicense, or otherwise convey his equity interest in PKI, if

of any provision of the PRTLA and causes PKI or the Company, with or without,
the passage of time, giving of notice, or action by any other Person, to lose or
diminish any rights to the Rx-Technology granted or maintained under the PRTLA.

          (c) Inforte Approval of Predictive Data Transactions. PKI shall not
enter into a limited liability company agreement or other formation document for

shall not be unreasonably withheld. PKI shall not cause Predictive Data to enter
into, or allow such action that would cause Predictive Data to be entered into,
any customer contracts for the provision of marketing processing services using
Rx-Technology ("Predictive Data Customer Contracts"), without first presenting
such Predictive Data Customer Contracts to Inforte for review and obtaining the
consent of Inforte to execute such Predictive Data Customer Contracts, which
consent shall not be unreasonably withheld. In connection with the foregoing,
upon the commencing of material negotiations with a prospective customer, PKI
shall notify Inforte and keep it informed with respect to any prospective
Predictive Data Agreement.

     Section 15.4 Indemnifications.

          (a) PKI and Conrad, jointly and severally, each hereby agree to

<PAGE>

asserted against, resulting to, imposed upon, or incurred by Inforte, Inforte
Affiliates, or the Company, directly or indirectly, by reason of, arising out of
or resulting from the inaccuracy or breach of any representation, warranty or
covenant of PKI or Conrad contained in or made pursuant to Article 15 of this
Agreement (regardless of whether such breach is deemed material).

          (b) Inforte hereby agrees to compensate, indemnify, defend, and hold
harmless PKI and its directors, officers, employees, and controlled and
controlling persons (collectively, "PKI Affiliates"), from and against all

     Section 15.5 Survival of PKI and Conrad Obligations. In the event that PKI
ceases to be a Member for any reason, PKI and Conrad agree that they shall

time periods prescribed in this Agreement.

                                  -------------

     Section 16.1 Amendments. Subject to Section 8.2, amendments may be made to
this Agreement from time to time with the written consent of Holders holding not
less than a majority of the Units; provided, however, that (i) this Section 16.1
may not be amended without the consent of all Members; (ii) the obligations of
any Member may not be increased nor be diminished, without the consent of such
Member; and (iii) neither this Agreement nor any term hereof may be amended,
waived, discharged or terminated in a manner that materially and adversely
affects a particular Member in a manner that is different from other Members,
except upon the written consent of such Member. Notwithstanding the foregoing,
the execution of a joinder or similar agreement by which a transferee of a
Member or a new Member agrees to be bound by and become a party to this
Agreement, and any change to the Unit Register made in connection therewith,
shall not be deemed an amendment.

     Section 16.2 Confidentiality. Each Member agrees that such Member will
utilize Confidential Information (as defined below) solely for the purpose of
the business of the Company and will make no other use of any Confidential
Information. For the purposes of this Agreement, "Confidential Information"
means that information which is confidential and proprietary to the Company and
which derives (or may derive) economic value to the Company by not being
generally known to others, or which the Company is otherwise under an agreement
of confidentiality with an unaffiliated third party. Confidential Information
shall not include any information which was: (i) in the public domain prior to
disclosure, or thereafter comes into the public domain without breach by such
Member of any confidentiality obligation hereunder; (ii) known by such Member
prior to disclosure to such Member, provided that such information is not known
by such Member to be subject to another confidentiality agreement or other
obligation of secrecy to another party; (iii) disclosed to such Member by a
third party not known to such Member to be in violation of any confidentiality
obligation owed to the Company; or (iv)


                                       32
<PAGE>


information required to be disclosed by law. Each Member agrees that such Member
will maintain and preserve the confidentiality and secrecy of such Confidential
Information, including, without limitation, taking such steps to preserve the
confidentiality of the Confidential Information as such Member takes to preserve
the confidentiality of such Member's own confidential information. In the event
that any Member becomes legally compelled to disclose any of the Confidential
Information, such Member shall provide the Company with prompt written notice of
such requirement so that the Company may seek a protective order or other
appropriate remedy. Each Member acknowledges and agrees that the Confidential
Information is and shall remain the property of the Company and that upon the
request of the Company, such Member shall promptly redeliver to the Company all
tangible expressions of the Confidential Information and will not retain any
copies, extracts, compilations, work product or other reproductions in whole or
in part of such Confidential Information. Notwithstanding the foregoing, the
Company, PKI, and Conrad acknowledge that as a public company registered with
Securities and Exchange Commission, Inforte is subject to federal and state
securities laws and regulations that may create a legal obligation to disclose
certain information that is Confidential Information under this Agreement.
Disclosure of Confidential Information, including the existence and terms of
this Agreement, pursuant to securities laws will not constitute a breach of this
Agreement.

     Section 16.3 Start-Up Expenses. Start-up expenses related to the Company
incurred by PKI and Inforte, including, but not limited to, costs of formation,
trade name search, and reasonable attorneys' fees in connection with the
drafting of agreements related to the organization and operation of the Company,
shall be paid by the Company.

     Section 16.4 Notices and Addresses. All notices required to be given under

          month; provided, however, that all outstanding Working Capital
          Advances and accrued interest thereon shall be due and owing in their
          entirety not later than the first anniversary date of the Limited
          Liability Company Agreement of PROVANSIS LLC An Inforte Company, as
          amended from time to time (the "Agreement"). Inforte shall have no
          obligation to fund Working Capital Advances after the Company
          commences generating positive cash flow on a regular basis.

     o    No indebtedness of the Company senior to Working Capital Advances
          shall be permitted.

     o    Notwithstanding any other provision of the Agreement, so long as there
          remains outstanding any Working Capital Advances, the Company shall
          make no distribution with respect to a Member's Membership Interest in
          an amount in excess of thirty percent (30%) of the Available Cash of
          the Company and then only after satisfaction of the Company's
          obligation set forth in Section 3.2(b) of the Agreement.

     o    Any of the following shall constitute an event of default: (i) the
          Company fails to pay when due any amount of the Working Capital
          Advances or accrued interest thereon; (ii) the Company or PKI fails to
          observe or perform any term of the Agreement, including, without
          limitation, the terms set forth in this Exhibit C; (iii) the Company
          defaults under the terms of any agreement or instrument

<PAGE>

          relating to any debt for borrowed money such that the creditor
          declares the debt due before its maturity; (iv) the Company becomes
          insolvent or unable to pay its debts as they become due; (v) the
          Company makes an assignment for the benefit of creditors; commences
          any proceeding under any bankruptcy, reorganization, liquidation or
          similar laws of any jurisdiction; or proceedings are commenced against
          the Company under any bankruptcy, reorganization, liquidation or
          similar laws of any jurisdiction; or (vi) there is a substantial
          change in the existing or prospective financial condition of the
          Company which Inforte in good faith determines to be materially
          adverse.

     o    Upon an event of default, Inforte's obligation to provide Working
          Capital Advances shall terminate and all outstanding Working Capital
          Advances and accrued interest thereon shall become due immediately, at
          Inforte's option.

     o    If the Working Capital Advances and accrued interest thereon are not
          paid at maturity, whether by acceleration or otherwise, Inforte shall
          have all the rights and remedies of a creditor provided by any law or
          agreement.

     o    No delay on the part of Inforte in exercising any right or remedy
          shall waive that right or remedy. No single or partial exercise by
          Inforte of any right or remedy shall preclude any other future
          exercise of it or the exercise of any other right or remedy. No waiver
          by Inforte of any default shall be effective unless it is in writing
          signed by Inforte, nor shall a waiver on one occasion bar or waive
          that right on any future occasion.

     o    The Company shall be liable to Inforte for all reasonable costs and
          expenses of every kind incurred in the collection of the Working
          Capital Advances and accrued interest, including, without limitation,
          attorneys' fees.

     o    The capitalized terms used in this Exhibit C shall have the same
          meanings ascribed to them in the Agreement.
