     Re:  Additional Rights Granted in Connection with the Purchase of the
          Convertible Promissory Notes
          ----------------------------------------------------------------

Ladies and Gentlemen:

          This letter (the "LETTER AGREEMENT") confirms our agreement that in
connection with the purchase by Cisco Systems, Inc., a California corporation
("CISCO"), of: (i) Convertible Promissory Note of Total Network Solutions, Inc.,
a New York corporation (the "COMPANY"), in the principal amount of $4,416,150.00
(the "COMMON CONVERTIBLE NOTE"), (ii) Convertible Promissory Note of the
Company, in the principal amount of $3,172,872.24 (the "FIRST CONVERTIBLE NOTE")
and (iii) Convertible Promissory Note of the Company in the principal amount of
$9,000,004.68 (the "SECOND CONVERTIBLE NOTE") (collectively, the "CONVERTIBLE
NOTES"), Cisco will be entitled to the following contractual rights in addition
to the other rights specifically provided for in the Convertible Promissory Note
Purchase Agreement (the "PURCHASE AGREEMENT"), Second Amended and Restated
Registration Rights Agreement and Second Amended and Restated Stockholders
Agreement (collectively, the "AGREEMENTS") being executed in connection with
Cisco's purchase of the Convertible Notes. All capitalized terms used herein but
not otherwise defined shall have the meanings assigned to them in the
Agreements.

1.   ACQUISITIONS; RIGHT OF NOTIFICATION; ACQUISITION PAYMENT.

     (A) NOTICE. In the event that the Board of Directors of the Company (i)
receives a bona fide offer in writing to be acquired by means of (x) a merger,
consolidation or other business combination pursuant to which the stockholders
of the Company immediately prior to the effective date of such transaction have
beneficial ownership of less than fifty percent (50%) of the total combined
voting power for election of directors of the surviving corporation immediately
following such transaction, or (y) the sale of all or substantially all of the
assets of the Company, or (ii) votes to initiate a sale to a Cisco Competitor of
(xx) twenty-five percent (25%) or more of the total voting power of the Company,
or (yy) all or substantially all of the Company's assets (each of these, an
"ACQUISITION PROPOSAL"), then prior to accepting such Acquisition Proposal, the
Company shall provide to Cisco written notice within 24 hours (the "NOTICE") of
the receipt of such bona fide offer or of such vote, as the case may be, of the
proposed terms of such Acquisition Proposal. The Acquisition Proposal may be
subject to customary conditions, such as the negotiation of a definitive
agreement. The Notice shall include the following information: (a) the identity
of the party making the Acquisition Proposal

<PAGE>

and (b) the material terms of the Acquisition Proposal, provided that, from and
after the earlier of December 31, 2000 or the completion of the Company's first
firm commitment underwritten offering pursuant to a registration statement under
the Securities and Exchange Act of 1933, as amended, covering the sale of the
Company's common stock with gross proceeds to the Company of at least Twenty
Million Dollars ($20,000,000) (the "Initial Public Offering"), the Company shall
not be required to disclose to Cisco any information that is subject to a
confidentiality obligation of the Company to any third party that is not a Cisco
Competitor (as defined below).

     (B) NEGOTIATION PERIOD. Cisco shall have a period of twenty (20) business
days, in the case of an Acquisition Proposal involving a Cisco Competitor (as
defined below), or ten (10) business days, in all other cases (which time period
may be extended by mutual written agreement), following its receipt of the
Notice ("NEGOTIATION PERIOD") in which to present to the Company a counter offer
("CISCO OFFER"). During such Negotiation Period, Cisco, at its sole option,
shall have the opportunity in such Cisco Offer either to match such Acquisition
Proposal or to propose to the Company's Board of Directors an alternative
acquisition proposal. TNS (i) may decline an alternative acquisition proposal
only in accordance with the procedures set forth in the second succeeding
sentence, (ii) may decline a matching offer and/or consummate the Acquisition
Proposal if the Board of Directors determines in good faith that such action is
required to comply with its fiduciary duties under applicable law, and (iii) may
decline a matching offer if the Acquisition Proposal both was unsolicited and is
not accepted by the Company. In any event, during such Negotiation Period Cisco
shall have the exclusive right to engage in negotiations with the Company with
respect to such Cisco Offer; PROVIDED, HOWEVER, that from and after the earlier
of December 31, 2000 or the completion of the Company's Initial Public Offering,
this sentence and the two previous sentences shall not apply to an Acquisition
Proposal received from a third party that is not a Cisco Competitor. In the
event: (i) Cisco does not deliver a Cisco Offer within the Negotiation Period,
(ii) Cisco notifies the Company, in writing, of Cisco's decision not to present
a Cisco Offer or (iii) the Company elects not to accept the Cisco Offer, which
election shall be subject to the Company's obligations under the second and
third preceding sentences, then, and only then, the Company shall be free, for a
period of ninety (90) calendar days following the expiration of the Negotiation
Period, to agree to accept the Acquisition Proposal on the terms and conditions
set forth in the Notice or on such other terms and conditions, in the aggregate,
not materially more favorable to the potential acquiror than those specified in
the Notice. Any proposed acquisition of the Company or sale of its assets
pursuant to an Acquisition Proposal after the end of such 90-day period or any
change in the terms of such Acquisition Proposal which are materially more
favorable to the potential acquiror shall require a new Notice, and shall give
rise anew to the rights of Cisco provided in this Section 1. If the terms of any
Acquisition Proposal include stock or other securities ("STOCK"), Cisco shall be
deemed to have matched the terms of such Acquisition Proposal if it agrees to
substitute for such Stock component of the Acquisition Proposal either cash or
Cisco's principal outstanding class of common equity ("Cisco Stock") having a
"fair market value" equivalent to the fair market value of the Stock component
of the subject Acquisition Proposal. "FAIR MARKET VALUE" shall mean, with
respect to the Stock of any potential acquiror or with regard to Cisco Stock (i)
which is traded on a nationally recognized exchange, the average of the three
(3) trading days closing price of such Stock on the date immediately prior to
the Cisco Offer; (ii) which is actively traded over-the-counter, the average of
the three (3) trading days closing sale price (or, if there is no sale on any
such trading day, the average of the closing bid and ask prices

                                       2
<PAGE>

for such day) of such Stock immediately prior to the Cisco Offer; and (iii) if
such Stock is not publicly traded, the value assigned to such Stock on the date
immediately prior to the Cisco Offer by Arthur Andersen LLP, or if Arthur
Andersen LLP is unwilling or unable to serve, by a nationally recognized
valuation agent designated by the mutual agreement of the Company and Cisco
within 15 days of a request for such designation by either party. The costs and
expenses incurred in connection with the valuation of the Stock by any
nationally recognized valuation agent designated by the previous sentence shall
be borne equally by Cisco and the Company. The fair market value of any other
non-cash consideration shall be determined in the same manner as for such
non-publicly traded stock.

     (C) DEFINITION OF CISCO COMPETITOR. For purposes of this Section 1, and
subject to the limitations in this subsection 1(c), "CISCO COMPETITOR" shall
mean any one of the seven (7) entities (which shall be deemed to include all of
such entities' subsidiaries or affiliates as defined below) that are listed in
SCHEDULE A hereto. For purposes of this Section 1, an entity shall be deemed to
be a subsidiary or affiliate of a Cisco Competitor if the Cisco Competitor has
beneficial ownership of 20% or more of such entity's common stock or any other
security convertible into or exercisable for common stock of such entity.

     (D) COMPETITOR ACQUISITION PAYMENT. In the event that, after compliance
with the other provisions of this Section 1, the Company accepts an Acquisition
Proposal from a Cisco Competitor, the Company shall pay to Cisco an amount equal
to five times (5x) the Company's last twelve (12) months' trailing revenues
(determined in accordance with GAAP), such twelve-month period to end as of the
last day of the month immediately prior to the month in which the closing of the
acquisition of the Company by a Cisco Competitor occurs. The amount payable
under this subsection 1(d) shall be paid to Cisco in immediately available funds
simultaneously with, and such payment obligation shall by contingent upon, the
closing of the acquisition of the Company by a Cisco Competitor. The Company and
Cisco agree that the relationship between Cisco and the Company is special and
unique, that the actual damages to Cisco arising from the loss of this special
relationship with the Company as a result of its acquisition by a Cisco
Competitor are difficult or impossible to determine with precision, and that the
amount payable under this subsection 1(d) represents a reasonable approximation
of the damages to Cisco from such an event.

     (E)  REDEMPTION OF CONVERTIBLE NOTES OR PREFERRED STOCK UPON ACQUISITION BY
COMPETITOR.

          (i) REDEMPTION OF CONVERTIBLE NOTES. In the event the Company accepts
an Acquisition Proposal from a Cisco Competitor, Cisco shall have the right, at
any time prior to closing of such a transaction, either to elect to have the
Company pay all or a portion of the outstanding principal and interest then due
under the Convertible Notes (other than the Common Convertible Note if there is
an active public trading market for the securities Cisco will receive upon
conversion of the Common Convertible Note immediately following the acquisition
of the Company) or to convert, in whole or in part, the Convertible Notes, in
each case in accordance with their terms.

          (ii) REDEMPTION OF PREFERRED STOCK. In the event the Company accepts
an Acquisition Proposal from a Cisco Competitor, Cisco shall have the right, at
any time

                                       3
<PAGE>

prior to closing of such a transaction, to elect to have the Company redeem all
or a portion of the shares of Series B or Series C Preferred Stock beneficially
owned by Cisco by paying the applicable liquidation preference of such shares.

          (iii) CLOSING CONTINGENCY. Any payment or conversion obligation
arising under clause (i) or (ii) above shall be satisfied simultaneously with,
and shall be contingent upon, the closing of the Acquisition Proposal the
acceptance of which gave rise thereto.

     (f) VOID TRANSACTIONS. Unless the Company shall have complied fully with
all of the procedures and requirements of this Section 1, then any Acquisition
Proposal which the Company may accept, and any transaction it may purport to
effect pursuant thereto, shall be void AB INITIO.

     (g) APPLICABILITY AND TERMINATION. Subsections 1(a) through (c) shall
terminate when Cisco no longer beneficially owns (within the meaning of Rule
13d-3 under the Securities Exchange Act of 1934, as amended) ("beneficially
owns") 25% of the shares of the Company's common stock beneficially owned by
Cisco immediately following the closing under the Purchase Agreement.
Subsections 1(d) and 1(e) shall terminate at such time as Cisco no longer
beneficially owns 50% the shares of the Company's common stock beneficially
owned by Cisco immediately following the closing under the Purchase Agreement.
Provided the Company has complied with the other subsections herein, Subsections
1(a) through 1(e) shall terminate upon the Company's becoming a party to a
merger, sale of assets or other reorganization in which the holders of the
outstanding shares of the Company prior to such transaction do not retain a
majority of the voting power of the surviving or transferee company or its
parent. Subsection 1(f) shall survive indefinitely.

2.   CONFIDENTIALITY.

     (a) PRESS RELEASES, ETC. Within sixty (60) days of the Closing, the Company
may issue a press release disclosing that Cisco has invested in the Company;
PROVIDED, that the final form of the press release is approved in advance in
writing by Cisco, such approval not to be unreasonably withheld. Except as
required by applicable law (including without limitation the rules and
regulations of the Securities and Exchange Commission), no other announcement
regarding Cisco's investment to the general public (except to potential bona
fide investors who are under appropriate nondisclosure obligations or in
connection with any roadshows arranged by the Company in preparation of
consummating an Initial Public Offering or pursuant to any pre-effective filing)
may be made without Cisco's prior written consent.

     (b) LEGALLY COMPELLED DISCLOSURE. Each of the Company and Cisco will
cooperate in the manner set forth below to seek confidential treatment relating
to any legally required disclosure of the confidential terms of the Agreements
or this Letter Agreement to the extent reasonably requested by the other. Cisco
acknowledges that the Company may be required in connection with consummating a
public offering, and thereafter in connection with various filings under
federal, state and foreign securities laws, to file the Agreements and/or this
Letter Agreement or describe the provisions thereof in publicly available
documents. The Company and Cisco agree, within 30 days prior to the Company's
initial filing with the SEC in connection with its initial public offering, to
meet to discuss the various provisions of the Agreements and/or Letter

                                       4
<PAGE>

Agreement for which the Company and/or Cisco wish to obtain confidential
treatment, provided that in no event shall the Company be required to request
confidential treatment of any provision of the Agreements or this Letter
Agreement which the lead managing underwriter reasonably requires to be
disclosed. Subject to the foregoing, upon request by Cisco pursuant to the
consultations conducted as a result of the preceding sentence, the Company will
use reasonable efforts to file a confidential treatment request and will
diligently respond with the input and advice of Cisco to SEC comments in
connection with such request; provided, however, that if confidential treatment
of any provision submitted is denied by the SEC staff reviewer, the Company
shall not be required to continue seeking confidential treatment for such
provision and in no event shall the Company be required to delay the
consummation of its initial public offering or any subsequent offering of its
securities because of any attempt to comply with this subsection.

3.   CONSULTING ENGAGEMENTS. The Company shall be one of Cisco's inner circle
of networking consultants. This inner circle is intended to be a limited number
of preferred networking consultants, currently comprised of four such companies.
In connection with the Company's preferred status, Cisco will use reasonable
efforts to offer the Company consulting engagements in amounts and frequency as
appropriate given the Company's resources and Cisco's business opportunities. If
the number of preferred networking consultants increases, then Cisco and the
Company shall discuss ways in which the Company would be able to continue to
enjoy the frequency and amounts of business it enjoyed when the number of
preferred networking consultants was no more than four. The parties agree that
the failure of either Cisco or the Company to offer such engagements or to
provide such services shall not give rise to an action for damages, specific
performance or any other legal or equitable remedy, or otherwise affect the
respective rights and obligations of the Company or Cisco under the Agreements
or this Letter Agreement.

4.   NON-ASSIGNABILITY. This Letter Agreement shall be binding on the Company
and its successors and permitted assigns. Neither the Company nor Cisco may
assign or transfer this Letter Agreement or any of its rights or obligations
hereunder (other than by operation of law) without the other party's prior
written consent; provided, however, that Cisco may transfer this Letter
Agreement and any of its rights and obligations hereunder to a majority-owned
affiliate thereof.

5.   APPLICABLE LAW. The validity, legality, enforceability and interpretation
of this Letter Agreement shall be governed by the laws of the State of
California without giving effect to principles of conflict of laws.

6.   HEADINGS. All Section and subsection headings herein are inserted for
convenience only and shall not modify or affect the construction or
interpretation of any provision of this Letter Agreement.

7.   SEVERABILITY. In the event any one or more of the provisions contained in
this Letter Agreement shall for any reason be held to be invalid, illegal or
unenforceable in any respect, such invalidity, illegality or unenforceability
shall not affect any other provision hereof, and this Letter Agreement shall be
construed as if such invalid, illegal or unenforceable provision had never been
contained herein.

                               ALLIANCE AGREEMENT

This Alliance Agreement is entered into on this day of , 2000 by and between
Total Network Solutions, Inc. with offices located at 545 Fifth Avenue, 14th
Floor, New York, NY 10017 ("TNS") and KPMG Consulting, LLC with offices located
at 500 East Middlefield Road, Mountain View, CA, 94043 ("KPMG").

1.       PURPOSE. KPMG, a provider of management consulting and system
         integration services, and TNS, a provider of network consulting
         services, desire to enter into this Alliance for the purpose of jointly
         pursuing global market opportunities for network integration, network
         and application performance solutions and related services, as agreed
         between the Parties (the "Target Markets") which are intended to result
         in new revenue to each company. The Alliance Agreement is intended to
         structure a relationship such that both KPMG and TNS view each other as
         business partners in both client delivery and new product development
         opportunities where jointly offering their respective expertise is
         anticipated to be effective.

         This Agreement covers certain activities necessary for the Parties to
         jointly develop and market specific offerings in the Target Markets.
         These activities include but are not limited to joint marketing
         programs, sales activities, proposal development, program development
         to package-integrated offerings, delivery, and support activities for
         joint network integration, and performance solutions. It is intended
         that multiple projects will be initiated under this Agreement and will
         be managed per the guidelines defined herein.

         The parties further intend that an Addendum for Participation will
         ultimately be the sole and exclusive vehicle for which KPMG member
         firms ("Member Firms") may participate or access this Agreement on a
         global basis. Each Member Firm that desires to participate under this
         Agreement, receive or have access to TNS' services must execute an
         Addendum for Participation in the form attached hereto as Exhibit B. If
         such addendum is not secured on behalf of a Member Firm, then such
         member Firm shall not be permitted to participate in this Agreement.

2.       PERIOD OF PERFORMANCE. This Agreement shall be effective for a period
         of one year. The parties may mutually agree to extend the term of this
         Agreement for two additional renewal periods. Either party may
         terminate this Agreement upon thirty (30) days prior written notice to
         the other party.

3.       SCOPE OF COOPERATION AND INITIAL PROJECTS. The cooperative efforts will
         focus initially on four categories:

         3.1   NETWORK INTEGRATION SOLUTIONS. KPMG and TNS will deliver
               offerings jointly targeted to network integration and directory
               enabled applications for IP based networks with the target market
               being enterprise and service provider accounts. The capabilities
               offered might include architectural design, network engineering,
               and network integration. In addition, both Parties may commit to
               working together on projects that result from any CISCO
               relationship(s) that either Party has which are

<PAGE>

               appropriate to the nature of this Alliance relationship. TNS will
               to the best of its ability introduce KPMG to existing and future
               client opportunities that may require solutions that are aligned
               with KPMG's core competencies that include, but are not limited
               to, IP Business Strategy, IP Based OSS/BSS integration, new
               service creation, directory enabled applications, and service
               provisioning (VPN, DSL, Cable modem). In turn, KPMG will to the
               best of its ability introduce TNS to existing and future client
               opportunities that may require solutions that are aligned with
               TNS's core competencies that may include network consulting
               services and performance solutions.

         3.2   TNS recognizes KPMG has a broad offering of services and
               solutions that may be useful to TNS'S installed client base and,
               where appropriate, TNS will introduce KPMG or recommend such
               services to its clients for the purpose of assisting KPMG in
               marketing KPMG's broader offerings and to assist the Parties in
               achieving the goals described in Section 5.4 below.

         3.3   NETWORK INTEGRATION OFFERINGS PACKAGED AROUND VERTICAL
               SOLUTION INITIATIVES. KPMG and TNS will attempt to develop
               packaged network integration service and performance offerings
               around KPMG led Industry focused Service solution initiatives,
               such as, but not limited to Self Service HR, Internet Commerce,
               e2e Supply Chain and R2I Oracle. TNS will incentivize its
               workforce to introduce client opportunities to KPMG that are
               outside its service offerings that are aligned with KPMG's core
               solutions such as, but not limited to customer management, ERP,
               CRM, supply chain management and e-Engineering.

         3.4  GEOGRAPHIC EXPANSION. KPMG IS INTERESTED IN EXPANDING PRESENCE AND
              DELIVERY CAPABILITY IN LATIN AMERICA, EUROPE AND ASIA. TNS and
              KPMG will work together to develop a market expansion plan for
              each region consistent with the available resources of each. To
              the extent possible, the parties will attempt to develop a
              cooperative relationship with their practices in Europe. The
              specifics of the offerings may be similar to the ones identified
              in Sections 3.1-3.3 above, or as mutually agreed between the
              Parties.

4.       TEAMING. The Parties contemplate that their collaboration described in
         Section 3 above will enable them to approach mutual customers in the
         Target Market in the following ways:

         4.1   One Party with an existing customer relationship may
               introduce the other Party to that customer, and will thereafter
               facilitate the introduced Party's marketing efforts to that
               customer - with each Party contracting directly with the mutual
               customer; or

         4.2   The Parties may team together to jointly present their
               respective offerings to a customer, and either: (a) as mutually
               agreed one Party will act as "prime contractor" to the customer,
               and the other Party will act as a subcontractor to the prime
               contractor in order to deliver specialized services and solutions
               to the customer; or (b) each Party will contract directly with
               the mutual customer for provision of its respective services and
               solutions. The Parties will enter into a definitive agreement
               before

                                       2
<PAGE>

               undertaking any project contemplated under subsection (a) above.
               The Parties agree to develop a Master Services Provisioning Plan
               that details how both parties will work together.

               Within 30 days of the Effective Date of this Alliance Agreement,
               the designated Alliance Managers will develop and publish a
               target account program and a project plan to focus their initial
               efforts.

5.       PERFORMANCE CONDITIONS AND GOALS.

         5.1   ALLIANCE MANAGERS. Both Parties shall designate an alliance
               manager to serve as the single point of contact to coordinate all
               activities between the Parties relative to this Agreement. These
               activities include joint account planning sessions, marketing,
               technical product development, and sales and solutions delivery.
               The following personnel will assist in managing the alliance:

                                 TNS                             KPMG
                                 ---                             ----

Alliance Manager              Giny Ellwell                  Sharon Hume

</TABLE>

         5.2   MARKETING AND SALES ACTIVITIES. Both Parties agree to jointly
               enter into marketing and sales activities. These activities shall
               include, but not be limited to the following: a joint marketing
               event calendar including but not limited to seminars and trade
               shows, collateral, white papers, a joint sales plan and sales
               kit. The Parties shall promptly create a co-marketing and sales
               plan which will identify specific targets, activities,
               responsibilities, and schedules to guide the Parties in these
               efforts. In that plan, both Parties will attempt to describe the
               Solution Development Roles and Responsibilities and the service
               Delivery Activities and Responsibilities. This plan will be
               evaluated quarterly by TNS and KPMG executive management and
               updated collaboratively as necessary by both Parties. All
               marketing material developed hereunder shall be subject to the
               reasonable review and approval of both Parties.

               Each Party will be responsible for its own marketing expenses.

         5.3   PERFORMANCE REVIEWS. Both Parties agree that the Alliance
               performance will be reviewed on a quarterly basis with a status
               report being prepared for the Executive sponsor of the respective
               organizations. The performance review shall include but not be
               limited to status on revenue generated by the alliance year to
               date, sales leads being pursued, planned marketing activity,
               joint development activity, and any issues or concerns.

         5.4   GOALS. Both Parties will attempt to achieve a minimum
               performance threshold for the Alliance to be meaningful to both
               parties. KPMG will to the best of its ability identify and assist
               TNS in closing deals with a revenue of $20,000,000 in the first
               year of this Agreement; $30,000,000 in the second year of this
               Agreement and

                                       3
<PAGE>

               $50,000,000 in the third year of this Agreement. TNS will to the
               best of its ability introduce KPMG, and assist KPMG in obtaining
               ten new accounts and in closing deals with a combined revenue of
               $25,000,000 each year of this Agreement. For the purposes of this
               section a "year" shall be considered a calendar year beginning
               January 1, 2000.

6.       TERMINATION FOR CAUSE.

         6.1   TERMINATION DUE TO MATERIAL CHANGES IN MARKET CONDITIONS.
               Should either Party reasonably conclude that there exists little
               or no market opportunity for their joint service offerings, then
               such Party shall have the option to terminate this Agreement upon
               thirty (30) days prior written notice to the other Party.

         6.2   TERMINATION FOR FAILURE TO MEET GOALS. If either Party does
               not meet it performance threshold under Section 5.4 the other
               Party shall have the option to terminate the alliance agreement
               upon thirty (30) days prior written notice to the non-performing
               Party. If either party determines that the Alliance is not
               resulting in mutually meaningful opportunities it may terminate
               this Agreement upon thirty (30) days prior written notice to the
               other party.

         6.3   CHANGE OF CONTROL. For purposes of this Section 6.3 any sale,
               assignment, pledge or other transfer of ten percent (10%)or more
               of any of the capital stock (or any other securities) of either
               Party will constitute a change of control. Upon execution of any
               of the above stated activities written notification must be
               provided by the Party undergoing the change of control within
               fifteen (15) days and the other Party shall have the option to
               terminate this Alliance Agreement upon thirty (30) days prior
               written notice, except that KPMG shall have the right to assign
               this Agreement, without the prior written consent of TNS to the
               successor to substantially all of the assets or business of KPMG.

         6.4   TERMINATION PROCESS. Should either Party allege that the
               other Party has materially breached this Agreement, the aggrieved
               Party shall provide notice in writing of such breach to the
               alliance manager of the Party that is alleged to be in breach.

               In the event that the two alliance managers cannot resolve the
               dispute within ten (10) business days, the dispute shall be
               escalated to the executive contacts of each company.

               In the event the executive contacts are not able to resolve the
               dispute within five (5) business days, either Party may terminate
               this Agreement immediately upon written notice to the other. In
               the event the resolution provides the breaching party with the
               opportunity to cure the breach, this Agreement shall terminate
               within fifteen (15) days of the date of notice if the breach is
               not cured.

               If the dispute is resolved, the resolution shall be provided in
               writing to both Parties within five (5) business days.

                                       4

         6.5   EFFECT OF TERMINATION. Unless the parties otherwise agree,
               Termination of this Agreement shall not impact any active
               engagements in process under a SOW.

               In the event of a termination of this Agreement, the Parties
               shall have no further obligation to each other, except for the
               obligation set forth in Sections 7, 8, 10 and 11.1, 11.2, and
               11.3.

               Upon any termination of this Agreement, each party shall
               immediately return all advertising materials and other
               properties, including Proprietary Information of the other Party,
               except KPMG may retain one copy to ensure compliance with
               professional practices. Both parties shall cease acting in a
               manner that would suggest any continuing relationship between the
               parties relating to this Alliance.

7.       MUTUAL CONFIDENTIALITY.

         7.1   MUTUAL CONFIDENTIALITY AGREEMENT. The mutual confidentiality
               Agreement that has been executed by the Parties is attached
               hereto as Exhibit A. All confidential information exchanged by
               the Parties will be governed by the terms of Exhibit A.

         7.2   PUBLIC DISCLOSURE. Neither Party may individually disclose
               and represent to clients or prospects the Alliance relationship,
               without the prior written approval of the other Party except to
               the extent necessary to perform its obligations hereunder. All
               press releases, public announcement, advertisement, publicity or
               any disclosures of a public nature require the approval of each
               Party's executive sponsor, except for any disclosures required to
               be made by law, regulation or court order. Neither party shall
               release any information concerning this Alliance, the parties
               relationship or any matters arising under this Agreement without
               the prior written approval of each party's executive sponsor.

         7.3   MARKS. The Parties agree that they will not use in any way
               the other party's name, trade names, trademarks, service marks or
               other proprietary designations of that party or its affiliates
               (collectively, "Marks") without the prior written consent of that
               party. Both parties acknowledges the other's exclusive right,
               title and interest in the others' Marks. Neither party will be
               deemed by anything in this Agreement, or actions taken pursuant
               to it, to acquire any right, title or interest in or to any
               Marks, or any portion of any marks.

         7.4   MUTUAL NON-SOLICITATION. Each Party will agree not to solicit
               employees of the other directly involved in providing the
               services under this Agreement during the term of the Alliance
               provided that any response by an employee of one Party to any
               advertisement of employment opportunities made by the other Party
               targeted to the general public shall not be deemed to be a breach
               of the foregoing provision.

8.       INTELLECTUAL PROPERTY.

         8.1   PRE-EXISTING PRODUCTS AND OTHER INTELLECTUAL PROPERTY. Each
               Party shall retain ownership of any of its pre-developed or
               separately developed intellectual property (e.g. proprietary
               software, commercial off-the-shelf products, platforms, drawings,
               reference models, libraries, and technical data). In particular,
               the separate property of TNS includes, but is not limited to,
               its proprietary methodology, the Productized Service offerings,
               and software, tools, specifications, drawings, sketches, models,
               samples, records and documentation, as well as copyrights,
               trademarks, service marks, ideas, concepts, know-how,
               methodologies, techniques, knowledge or data, which have been
               originated, developed or purchased by TNS. The separate property
               of KPMG includes, but is not limited to, OSS/BSS templates and
               methodologies, software, tools, specifications, drawings,
               sketches, models, samples, records and documentation, as well as
               copyrights, trademarks, service marks, ideas, concepts, know-how,
               methodologies, techniques, knowledge or data, which have been
               originated, developed or purchased by KPMG. Neither Party shall
               have the right to use the intellectual property of the other
               without the prior written consent of the other Party, provided
               however, to the extent that any separate intellectual property of
               either Party is utilized in the development of any service or
               software initiatives jointly developed by the Parties under this
               Alliance Agreement, the owner of such separate intellectual
               property grants to the other a license to use such separate
               intellectual property during the term of this Alliance Agreement
               only to the extent necessary to meet the initiatives established
               herein.

         8.2   JOINTLY DEVELOPED INTELLECTUAL PROPERTY. Inventions conceived
               solely by employees of TNS shall belong exclusively to TNS.
               Inventions conceived solely by employees of KPMG shall belong
               exclusively to KPMG. Upon the development of Jointly Developed
               Intellectual Property, the Parties shall mutually agree to the
               ownership of such Jointly Owned Intellectual Property. Jointly
               Owned Intellectual Property shall mean all inventions,
               discoveries, technologies, patents, know-how, trademarks,
               copyrights, service marks, trade secrets, methods, tools,
               routines, techniques, methodologies, know-how, computer programs,
               utilities, ideas, process and practices developed jointly by both
               Parties under this Agreement. This section may be modified as
               required by applicable governmental regulations or the terms of
               the prime contract or resultant subcontract between the parties.
               Except as stated above, nothing contained in this Agreement shall
               be deemed, by implication, estoppel or otherwise, to grant any
               right or license in respect of patents, inventions or technical
               information at any time owned by the other party.

9.       FINANCIAL PERFORMANCE. The intent of this Alliance is to generate new
         revenues for each of the Parties. Each Party agrees to use commercially
         reasonable efforts to achieve the following:

         9.1   ANNUAL REVENUES. Failure to achieve the any hoped for
               financial goals specified in Section 5.4 shall not be deemed a
               material breach of this Agreement. Neither party shall have any
               liability if it fails to successfully promote the products and/or
               services of the other party.

10.      REPRESENTATIONS AND WARRANTIES

         Each party hereby represents and warrants to the other that:

         (a) it has the right and power to enter into this Agreement and to
         grant and convey the rights granted;

         (b) entering into this Agreement does not violate the terms and
         conditions of any other agreement, or any applicable, law, rule or
         regulation;

         (c) to the best of its knowledge, the information which it may disclose
         to the other party, and the process of disclosure and the use of such
         information in accordance with this Agreement will not violate any
         trade secret, trademark, patent, copyright or other proprietary right
         of any third party;

         (d) it holds good title or right, free and clear of all liens and
         encumbrances, to the Products and Services which it is providing under
         this Agreement;

         (e) the Products and Services being provided under this Agreement do
         not infringe any copyright, trademark, patent, trade secret or other
         proprietary right of any third party; and

         (f) EXCEPT AS SPECIFICALLY SET FORTH IN THIS SECTION, NEITHER PARTY
         MAKES ANY OTHER WARRANTY AND EACH PARTY HEREBY DISCLAIMS, ALL OTHER
         WARRANTIES, EITHER EXPRESS, IMPLIED OR STATUTORY, OR ARISING BY COURSE
         OF CONDUCT OR PERFORMANCE, CUSTOM OR USAGE OF TRADE, INCLUDING BUT NOT
         LIMITED TO ANY IMPLIED WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A
         PARTICULAR PURPOSE.

11.      GENERAL.

         11.1  Each Party hereby agrees to indemnify, hold harmless and
               defend the other Party from and against any and all claims,
               liabilities, losses, expenses (including reasonable attorneys'
               fees), fines, penalties, taxes or damages (collectively
               "Liabilities") asserted against such other Party by a third party
               to the extent such Liabilities result from the claim that the use
               of the Indemnifying Party's product constitutes infringement of
               any third party's patent issued as of the date of this Agreement
               trade secret, trademark or copyright; provided, that such
               indemnified Party (i) promptly notifies the indemnifying Party of
               any third party claim subject to indemnification hereunder, (ii)
               gives the indemnifying Party the right to control and direct the
               preparation, defense and settlement of any such claim and (iii)
               gives full cooperation to the indemnifying Party for the defense
               of same. The foregoing provisions shall not apply to any
               infringement arising out of: (i) use of the applicable
               intellectual property other than in accordance with applicable
               documentation or instructions supplied by the indemnifying Party;
               (ii) any alteration, modification or revision of the applicable
               intellectual property not expressly authorized in writing by the
               indemnifying Party;

                                       7
<PAGE>

               or (iii) the combination of the applicable intellectual property
               with materials not supplied by the indemnifying Party.

               EXCEPT WITH RESPECT TO SUCH PARTY'S OBLIGATIONS PURSUANT TO
               INFRINGMENT HEREOF, EACH PARTY'S MAXIMUM LIABILITY TO THE OTHER
               PARTY ARISING FOR ANY REASON RELATING TO THIS AGREEMENT SHALL BE
               LIMITED TO THE AMOUNT RECEIVED UNDER THE SOW TO WHICH THE CLAIM
               IS REFERRED.

               NEITHER PARTY SHALL BE LIABLE FOR ANY INDIRECT, PUNITIVE,
               SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES IN CONNECTION WITH
               OR ARISING OUT OF THIS AGREEMENT (INCLUDING LOSS OF PROFITS),
               HOWSOEVER ARISING, EVEN IF SUCH PARTY HAS BEEN ADVISED OF THE
               POSSIBILITY OF SUCH DAMAGES.

         11.2  INDEPENDENT CONTRACTORS. Each party acknowledges that it is
               not and shall not hold itself out as, a joint venturer,
               franchisee, partner, employee, servant, representative or agent
               of the other party. It is expressly agreed that the parties are
               acting as independent contractors for their own account and under
               no circumstances shall any employee of one party be deemed an
               employee of the other party for any purpose. This agreement shall
               not be construed as authority for any party to act for another
               party in any agency or other capacity, or to make commitments of
               any kind for the account of or on behalf of the other party.
               Neither party is responsible to any Customer for the quality of
               Services or Products provided by the other party.

         11.3  Neither party is or may act as a distributor or agent for
               the products or services of the other Party. Each party's
               products and services shall be available to a prospective
               Customer only through a separate agreement between that party and
               the Customer, unless the parties agree to a subcontractor
               relationship for a particular engagement. Each party shall
               independently develop and price its respective products and
               services in a separate agreement between such party and the
               Customer or as may be agreed to in a SOW or subcontractor
               agreement. No Party shall be or become liable or bound by any
               representation, act or omission whatsoever of any other Party.

         11.4  All costs incurred by each Party in connection with this
               Alliance shall be the responsibility of the Party incurring the
               costs, unless a written agreement executed by the Parties'
               authorized representatives has been signed that expresses a
               specific agreement with respect to certain costs.

         11.5  Neither party shall assign, transfer, or subcontract this
               Agreement or any of its obligations hereunder without the other
               party's express, prior written consent. Notwithstanding the
               foregoing, KPMG shall have the right to assign without prior
               consent or approval of TNS to the successor to substantially all
               of the assets and business of KPMG.

         11.6  This Alliance Agreement constitutes the entire agreement
               between the Parties and may not be amended excepted in writing
               signed by an officer of both Parties. This

                                       8
<PAGE>

               Agreement shall be governed by the laws of New York, without
               regard to any conflict of laws provisions.

         11.7  This Agreement is non-exclusive. Nothing in this Agreement
               shall limit or restrict either party from entering into or
               continuing any agreement or other arrangement with any third
               party, whether or not similar to this Agreement in nature and
               scope.

"Discloser or the "Disclosing Party") are KPMG and TNS.

disclosure or receipt of confidential information is:

KPMG:                      Dick Kearney

TNS:                       Bob Foley

3.  DESCRIPTION OF CONFIDENTIAL INFORMATION: "Confidential Information" means
any information, technical data, or know-how (including, but not limited to,
information relating to research, products, software, services, development,
inventions, processes, engineering, marketing, techniques, customers, pricing,
internal procedures, business and marketing plans or strategies, finances,
employees and business opportunities) disclosed by the Disclosing Party to a
Recipient either directly or indirectly in any form whatsoever (including, but
not limited to, in writing, in machine readable or other tangible form, orally
or visually): (i) that has been marked as confidential; (ii) whose confidential
nature has been made known by Disclosing Party, orally or in writing, to such
Recipient; or (iii) that due to its character and nature, a reasonable person
under like circumstances would treat as confidential.

4.  USE OF CONFIDENTIAL INFORMATION: The Party receiving confidential
information ("Recipient") shall make use of the confidential information only
for the furtherance of any mutually agreed upon projects and engagements.
Recipient agrees not to use the Confidential Information for its own use or for
any purposes except those purposes expressly set forth above. Recipient shall
not use the Confidential Information for purposes of unfair or improper
competition. Recipient agrees not to copy, alter, modify, disassemble, reverse
engineer or decompile any of the materials unless permitted in writing by the
Disclosing Party.

5.  CONFIDENTIALITY PERIOD: This Agreement and Recipient's duty to hold
confidential information in confidence shall survive any expiration or
termination of this Agreement in perpetuity.

6.  DISCLOSURE PERIOD: This Agreement pertains to confidential information that
is disclosed between the Effective Date and the date any Party hereto terminates

Information to any third parties or to any of its employees except those
employees who have a need to know the Confidential Information for accomplishing
the stated purposes described herein and where such

employees shall be made aware that the information is confidential and shall be
under a written contractual restriction on nondisclosure and proper treatment of
confidential information that is no less restrictive than the terms of this
Agreement. Notwithstanding the foregoing, Recipient may disclose the Disclosing
Party's Confidential Information to the extent required by a valid order by a
court or other governmental body or by applicable law; provided, however, that
Recipient will use all reasonable efforts to notify Disclosing Party of the
obligation to make such disclosure in advance of the disclosure so that
Disclosing Party will have a reasonable opportunity to object to such
disclosure.

Recipient shall protect the disclosed confidential information by using the same
degree of care, but no less than a reasonable degree of care, to prevent the
unauthorized use, dissemination, or publication of the confidential information
as Recipient uses to protect its own confidential information of a like nature.
Recipient agrees to advise the Disclosing Party in writing of any
misappropriation or misuse by any person of such Confidential Information of
which Recipient may become aware.

to information that: (a) was in Recipient's possession before receipt from
Discloser; (b) is or becomes a matter of public knowledge through no fault of
Recipient; (c) is rightfully received by Recipient from a third Party without a
duty of confidentiality; (d) is disclosed by Discloser to a third party without
a duty of confidentiality on the third party; (e) is independently developed by
Recipient without reference to another party's Confidential Information; (f) is
disclosed under operation of law; or (g) is disclosed by Recipient with
Discloser's prior written approval.

disclosures under this Agreement. NO OTHER WARRANTIES ARE MADE BY EITHER PARTY
