                             REIMBURSEMENT AGREEMENT

      AGREEMENT made this 18th day of October 2002 by and between AIG HIGHSTAR
CAPITAL, L.P., a Delaware limited partnership ("AIG Highstar"), having an office
at 175 Water Street, 26th Floor, New York, New York 10038, TRANSCORE HOLDINGS,
INC., a Delaware corporation ("TransCore") having an office at 8158 Adams Drive,
Liberty Center - Building 200, Hummelstown, Pennsylvania 17036, and TRANS CORE
CREDIT CORPORATION, a Delaware corporation and wholly owned subsidiary of
TransCore ("TCC"), having an office at 8158 Adams Drive, Liberty Center -
Building 200, Hummelstown, Pennsylvania 17036.

                                   BACKGROUND

      TransCore, among other things, provides technology-based services to
entities to manage ground transportation systems, assets and transactions.

      As a routine part of its business and to secure its obligations under
contracts, TransCore must deliver to its customers surety bonds issued by
licensed surety companies.

      In a typical surety bond arrangement, the surety company issues its bond
to an obligee guaranteeing TransCore's performance under a contract in exchange
for a premium and a contractual undertaking by TransCore, as principal, to
reimburse the surety company if it is required to perform under the bond.

      TransCore has experienced rapid growth and an accompanying need for
additional capacity to obtain and deliver surety bonds.

      In order to support additional bonding capacity, TransCore is seeking to
establish a dedicated first loss indemnity pool of capital to support the
underwriting and issuance of surety bonds by surety companies on behalf of
TransCore.

      AIG Highstar is an existing investor in TransCore and holds 218 shares of
TransCore Class A preferred stock, 103,328 shares of Class C-1 convertible
preferred stock, $2,200,000 of subordinated debt, a warrant to acquire 10,920.5
shares of TransCore Class A Common Stock and a warrant to acquire 219 shares of
Class B Common Stock.

      AIG Highstar has agreed, in consideration for a Warrant to purchase 46,680
shares of TransCore Class A Common Stock at a price of $.01 per share and
certain other consideration, to invest up to $20 million in a bankruptcy remote
subsidiary of TransCore to provide the capital necessary to increase the ability
of TransCore to obtain and deliver surety bonds.

                                       1

<PAGE>

      TransCore has formed TCC as a bankruptcy remote, wholly owned subsidiary
solely for the purpose of entering into this Agreement (along with any necessary
supporting agreements) and creating a first loss indemnity pool of capital to
support the issuance of surety bonds on behalf of TransCore and related
activities.

      TransCore has agreed to reimburse AIG Highstar for any payments made by
AIG Highstar to TCC on behalf of TransCore under the terms of this Agreement.

            Commitment shall be the AIG Highstar Payment Limit less the sum of
            the then existing or outstanding: (i) AIG Highstar Payments, and
            (ii) the stated amount of any outstanding Substitute Letters of

                  (c)   After the expiration of the AIG Highstar Payment
            Commitment Period, the AIG Highstar Payment Commitment shall be zero
            and no portion of the AIG Highstar Payment Commitment shall be used
            in respect of a TCC Obligation that extends beyond the AIG Highstar
            Payment Commitment Period.

            3.3.  Identification of TCC Obligations. TCC shall identify each TCC
      Obligation by delivery to AIG Highstar and the Issuer of a TCC Obligation
      Notice in the form attached as Exhibit A hereto. Each TCC Obligation
      Notice shall be delivered by TCC to AIG Highstar and the Issuer within ten
      (10) Business Days after the issuance date of the Surety Bond Agreement to
      which it relates.

            3.4.  Substitute Letters of Credit; Letter of Credit Fee.
      Notwithstanding anything contained herein to the contrary, upon the
      written request of an Issuer to TransCore or TCC, and delivery of a
      Substitute Letter of Credit Notice from TCC to AIG Highstar in the form
      attached hereto as Exhibit B, AIG Highstar shall deliver to TCC a
      Substitute Letter of Credit in substantially the form attached hereto as
      Exhibit C within twelve (12) Business Days of such request. The amount of
      the AIG Highstar Payment Commitment shall be reduced by the stated amount
      of the Substitute Letter of Credit for so long as such Substitute Letter
      of Credit is outstanding. Such delivery shall occur contemporaneously with
      the execution of a Surety Bond Agreement by TCC and the Issuer and the
      creation of a TCC Obligation. If AIG Highstar is required to issue to TCC
      a Substitute Letter of Credit, TransCore shall pay to AIG Highstar an
      amount equal to 1.25% per annum of the aggregate amount of any such
      Substitute Letters of Credit issued and outstanding, payable quarterly in
      arrears.

            3.5.  Non-exclusive Bonding Facility. Nothing contained in this
      Agreement shall in any way require that TransCore cannot satisfy its
      bonding requirements directly or in any other manner that TransCore, in
      its sole discretion, shall determine.

            SECTION 4. TCC PAYMENTS

            4.1.  Demand for Payment. Upon payment by an Issuer to an Eligible
      Obligee in connection with an Eligible Bond, TransCore shall make a demand
      for a TCC Payment by delivery to TCC of a written TCC Payment Certificate
      signed by an Authorized Officer of TransCore in the form attached hereto
      as Exhibit D. The TCC Payment Certificate shall reference the Surety Bond
      Agreement previously executed by TCC related to the Eligible Bond under
      which payment was made by the Issuer to an Eligible Obligee and state that
      TCC, as first loss indemnitor under such Surety Bond Agreement, is
      obligated to make a payment to the Issuer referenced in such Surety Bond
      Agreement and shall specify the amount of such payment. In the event that
      the TCC Payment Certificate is for an amount less than the amount
      specified in the original TCC Obligation related to such Surety Bond
      Agreement, such TCC Obligation immediately shall be reduced by the amount
      specified in the TCC Payment Certificate paid by TCC.

      5.1 of this Agreement.

      the issuing bank.

            5.2.  Presentation. Presentation of a AIG Highstar Payment

      Highstar on the twelfth (12th) succeeding Business Day. Payment against
      any AIG Highstar Payment Certificate indicating a payment date which is
      not a Business Day will be effected on the next succeeding Business Day.
      If an AIG Highstar Payment Certificate hereunder does not, in any
      instance, conform to the terms and conditions of this Agreement, AIG
      Highstar shall give TCC prompt notice that the purported AIG Highstar
      Payment Certificate was not effected in accordance with the terms and
      conditions of this Agreement, stating the reasons therefor and that AIG

            SECTION 11. REPRESENTATIONS OF TRANSCORE

            To induce AIG Highstar and TCC to enter into this Agreement,
      TransCore represents and warrants to AIG Highstar and TCC that:

            11.1. Organization and Corporate Power. Each of TransCore and its
      Subsidiaries is duly organized, validly existing and in good standing
      under the laws of the jurisdiction of its formation and is qualified to do
      business in the jurisdictions listed on the attached "Qualifications
      Schedule," except as noted therein, which list includes every jurisdiction
      where the failure to so qualify might reasonably be expected to have a
      Material Adverse Effect. Each of TransCore and its Subsidiaries has the
      requisite power and authority to execute, deliver and carry out its
      respective obligations under each of the Transaction Documents. Each of
      TransCore and its Subsidiaries has all requisite power and authority and
      all material licenses, permits and authorizations necessary to own and
      operate its respective properties, to carry on its respective businesses
      as now conducted and presently proposed to be conducted and to carry out
      the Transaction. The copies of each of TransCore's and its Subsidiaries'
      Charter Documents which have been furnished to AIG Highstar reflect all
      amendments made thereto at any time prior to the date of this Agreement
      and are correct and complete.

            11.2. Capital Stock and Related Matters.

                  (a)   As of the Closing and immediately thereafter, the
            authorized Capital Stock of TransCore is as set forth on the
            attached "Capitalization Schedule." As of the Closing, TransCore
            will not be subject to any obligation (contingent or otherwise) to
            repurchase or otherwise acquire or retire any shares of its Capital
            Stock, (including the Schedules hereto), except as set forth in the
            Shareholders' Agreement or the Charter Documents of TransCore. As of
            the Closing, all of the outstanding shares of TransCore's Capital
            Stock will be validly issued, fully paid and non-assessable.

                  (b)   TransCore has not violated any applicable federal or
            state securities laws in connection with the offer, sale or issuance
            of any of its Capital Stock, or the offer, sale and issuance of the
            Warrant to AIG Highstar pursuant to and in the manner contemplated
            by this Agreement and such issuance does not and will not, require
            registration under the Securities Act of 1933, as amended, or any
            applicable state securities laws. Except as set forth in the
            Shareholders' Agreement, there are no agreements between TransCore's
            shareholders with respect to the voting or transfer of TransCore's
            Capital Stock.

            11.3. Subsidiary. Except for the Subsidiaries set forth on the
      "Subsidiaries Schedule" hereto, TransCore does not hold any rights to
      acquire any shares of stock or any other security or interest in any other
      Person.

            11.4. Authorization; No Breach. TransCore has duly authorized the
      execution, delivery and performance of its obligations under the
      Transaction Documents. The execution and delivery by TransCore of the
      Transaction Documents does not and will not (i) conflict with or result in
      a breach of the terms, conditions or provisions of, or (ii) result in the
      creation of any lien, security interest, charge or encumbrance upon any of
      TransCore's capital stock, assets or property now owned or hereafter
      acquired, or (iii) give any third party the right to accelerate any
      obligation, or (iv) result in a violation of, or (v) require any
      authorization, consent, approval, exemption or other action by or notice
      to any court or administrative or governmental body pursuant to the
      Charter Documents of TransCore, or any law, statute, rule or regulation to
      which TransCore is subject, or any agreement, instrument, order, judgment
      or decree to which TransCore is a party or to which it or its assets are
      subject.

            11.5. Governmental Approval. No registration with or consent or
      approval of, or other action by, any federal, state or other governmental
      agency, authority or regulatory body is or will be required in connection
      with the consummation of the Transaction by TransCore or its Subsidiaries.

            11.6. Enforceability. This Agreement, when executed and delivered to
      AIG Highstar and TCC, will constitute valid obligations of TransCore
      legally binding upon it and enforceable in accordance with its terms,
      except as enforceability of the foregoing may be limited by bankruptcy,
      insolvency or other laws of general application relating to or affecting
      the

                                       18

<PAGE>

      enforcement of creditors' rights.

            11.7. Financial Matters. TransCore has furnished to AIG Highstar a
      copy of (i) the consolidated audited balance sheet of TransCore and its
      Subsidiaries for the fiscal year ending on January 31, 2002 and the
      related statement of income and (ii) the consolidated unaudited balance
      sheet of TransCore and its Subsidiaries as of July 31, 2002, and the
      related statement of income for the six-month period then ended. Such
      financial statements present fairly in accordance with GAAP, the financial
      position of TransCore at the date thereof and the results of operations of
      TransCore for the periods then ended, subject to normal year-end
      adjustments. Except as disclosed or reflected in such financial
      statements, neither TransCore nor any of its Subsidiaries had any material
      liabilities, contingent or otherwise, and there were no material
      unrealized or anticipated losses of TransCore or any of its Subsidiaries.

            11.8. No Material Adverse Change. Since January 31, 2002, there has
      been no event or occurrence that would reasonably be expected to have a
      Material Adverse Effect, provided, however, that neither the accounting
      irregularities heretofore disclosed with respect to the acquired
      subsidiary Viastar Holdings, Inc. nor the inability to secure surety bonds
      as of the date of this Agreement shall be deemed to be a Material Adverse
      Effect.

            11.9. Litigation. Except as described in the "Litigation Schedule",
      no actions, suits or proceedings before any court or governmental
      department or agency (whether or not purportedly on behalf of TransCore)
      are pending or, to the knowledge of TransCore, threatened (a) with respect
      to any of the transactions contemplated by this Agreement or (b) against
      or affecting TransCore or any of its properties that, if adversely
      determined, could reasonably be expected to have a material adverse effect
      on TransCore.

            11.10. Compliance with Laws. TransCore and its Subsidiaries are not
      in violation in any material respect of any applicable law, rule or
      regulation, including but not limited to, any Environmental Law. TransCore
      and its Subsidiaries are not in default with respect to any judgment,
      writ, injunction, decree, rule or regulation of any court or governmental
      agency or instrumentality. During the past ten (10) years, none of the
      current officers, directors or management of TransCore or any of its
      Subsidiaries have been arrested or convicted of any material crime nor
      have any of them been bankrupt or, except as disclosed on the attached
      "Compliance with Laws Schedule," an officer or director of a bankrupt
      company.

            11.11. Environmental Protection. Except as specified in the
      "Environmental Schedule" and after giving effect to the Transactions: (a)
      TransCore and its Subsidiaries, the methods and means employed by them in
      the operation thereof (including all operations and conditions at or in
      the properties of TransCore), and the assets owned, leased, held or
      operated by them, comply in all material respects with all applicable
      laws, rules, regulations, ordinances and codes of every kind, including
      Environmental Laws; (b) TransCore and its Subsidiaries have obtained all
      permits under Environmental Laws necessary to their operations other than
      such permits the absence of which could not, individually or in the
      aggregate, result in a Material Adverse Effect, and all such permits are
      in good standing and they are in compliance with all material terms and
      conditions of

                                       19

<PAGE>

      such permits; and (c) neither TransCore nor any of its Subsidiaries has
      received (i) any claim or notice of violation, lien, complaint, suit,
      order or other claim or notice to the effect that they are or may be
      liable to any Person as a result of (A) the environmental condition of any
      of their respective properties or any other property, or (B) the release
      or threatened release of any Hazardous Materials, or (ii) any letter or
      request for information under Section 104 of the Comprehensive
      Environmental Response, Compensation and Liability Act of 1980, as amended
      (42 U.S.C.Section 9604), or comparable state laws, and to the best of
      TransCore's knowledge, none of the operations of TransCore or its
      Subsidiaries are the subject of any Federal or state investigation
      evaluating whether any remedial action is needed to respond to a release
      or threatened release of any Hazardous Material at TransCore's or any of
      its Subsidiaries' properties or at any other location, including any
      location to which TransCore or its Subsidiaries has transported, or
      arranged for the transportation of, any Hazardous Materials.

            11.12. Taxes. TransCore and its Subsidiaries have filed or caused to
      be filed all federal, state and local tax returns which are required to be

      and payable on such returns or on any assessments received by it,
      including payroll taxes.

            11.13. Labor and Employment. TransCore, its Subsidiaries and each
      Plan is in compliance in all material respects with those provisions of
      ERISA, the Internal Revenue Code, the Age Discrimination in Employment
      Act, and the regulations and published interpretations thereunder which
      are applicable to TransCore, its Subsidiaries or such Plan. As of the date
      hereof, no Reportable Event has occurred with respect to any Plan as to
      which TransCore or its Subsidiaries was required to file a report with the
      Pension Benefit Guaranty Corporation. No Plan has any material amount of
      unfunded benefit liabilities (within the meaning of Section 4001 (a)(I 8)
      of ERISA) or any accumulated funding deficiency (within the meaning of
      Section 302 (a)(2) of ERISA), whether or not waived, and neither TransCore
      nor any of its Subsidiaries has incurred or expects to incur any material
      withdrawal liability under Subtitle E of Title IV of ERISA to a
      Multi-employer Plan. No Plan of TransCore or its Subsidiaries obligates it
      to provide post-retirement medical benefits, except as may be required by
      the Consolidated Omnibus Budget Reconciliation Act of 1986. TransCore and
      its Subsidiaries are in compliance in all material respects with all labor
      and employment laws, rules, regulations and requirements of all applicable
      domestic and foreign jurisdictions. There are no pending or threatened
      labor disputes, work stoppages or strikes.

            11.14. Investment Company Act; Public Utility Holding Company Act.
      Neither TransCore nor any of its Subsidiaries is (a) an "investment
      company" within the meaning of the Investment Company Act of 1940, as
      amended or (b) a "holding company" or a "subsidiary company" of a "holding
      company" or an "affiliate" of a "holding company" or of a "subsidiary
      company" of a "holding company," within the meaning of the Public Utility
      Holding Company Act of 1935, as amended.

            11.15. Properties; Security Interests. TransCore and its
      Subsidiaries have good title to, or valid leasehold interests in all of
      the material assets and properties reflected in the balance

      Liens. All such assets and properties are in good repair, working order
      and condition and all such assets and properties are owned by TransCore

            11.16. Intellectual Property; Licenses. TransCore and its
      Subsidiaries possess all Proprietary Rights necessary to conduct their
      business as heretofore conducted. All Proprietary Rights registered in the
      name of TransCore or any Subsidiary and applications therefor filed by
      TransCore or any Subsidiary are listed on the "Intellectual Property
      Schedule." No event has occurred that permits, or after notice or lapse of
      time or both would permit, the revocation or termination of any of the
      foregoing which taken in isolation or when considered with all other such
      revocations or terminations could result in a Material Adverse Effect.
      TransCore does not have notice or knowledge of any facts or any past,
      present or threatened occurrence that could preclude or impair TransCore's
      or any of its Subsidiaries' ability to retain or obtain any authorization
      necessary for the operation of its business.

            11.17. Solvency. Except as set forth in the "Solvency Schedule"

      on behalf of TransCore to AIG Highstar and TCC for purposes of or in

      accurate in all material respects on the date as of which such information
      is furnished and not incomplete by omitting to state any fact necessary to

      circumstances under which such information was provided.

      with any individual or business, pursuant to which the director, officer,
      employee, Company or such Affiliate has agreed to do anything beyond the
      requirements of the formal, written contracts executed by TransCore.

      formalities, including the maintenance of current minute books, and shall
      cause any financial statements to be prepared in accordance with GAAP in a
      manner that indicates the separate existence of TCC and its assets and
      liabilities. Other than those liabilities associated with the issuance of
      Eligible Bonds, TCC shall not assume the liabilities of TransCore or any
      Affiliate of TransCore, and shall not guarantee the liabilities of

      TransCore shall have the sole authority to approve or disapprove the
      annual operating budget and shall do so before the beginning of each year.

            14.5. Modification. Without the prior written consent of TCC and AIG
      Highstar, which consent shall not be unreasonably withheld, TransCore may
      not modify any Surety Bond Agreement with any Issuer, including, without
      limitation, modification of any reimbursement obligation, or modify the
      related Eligible Bond, except for any such modification that: (i) reduces

                                       24

<PAGE>

      the amount of the Eligible Bond, or (ii) alters the maturity of the
      Eligible Bond or the reimbursement obligation in the Surety Bond Agreement
      in a manner that, if such alterations were the original terms, the surety
      bond would not fail to qualify as an Eligible Bond. Notwithstanding the
      foregoing, AIG Highstar may withhold its consent to any such modification
      where such modification, in the sole judgment of AIG Highstar, may have a
      material adverse effect on AIG Highstar's rights hereunder.

            SECTION 15. INDEMNIFICATION.

            15.1. Indemnification by TransCore. TransCore hereby agrees to
      indemnify, defend and hold harmless AIG Highstar and TCC and their
      respective officers, directors, employees, agents and representatives
      ("Representatives"), and their respective successors and assigns in
      connection with any losses, claims, damages, liabilities and expenses,
      including AIG Highstar Payments, TCC Payments or reasonable attorneys'
      fees, to which AIG Highstar or TCC or their respective Representatives may
      become subject (other than as a result of the willful misconduct of any
      such Person), insofar as such, losses, claims, damages or liabilities (or
      actions in respect thereof) arise out of payment by AIG Highstar of any
      AIG Highstar Payment, payment by TCC of any TCC Obligation, material
      breach of any Environmental Law or by reason of any investigation,
      litigation or other proceedings related to or resulting from any act o1 or
      omission by, TransCore or its Affiliates or any TransCore or Affiliate
      Representative with respect to the Transaction or the Transaction
      Documents and to reimburse AIG Highstar, TCC and each such Person and
      Affiliate, upon demand, for any legal or other expenses incurred in
      connection with investigating or defending any such loss, claim, damage,
      liability, expense, or action. To the extent that the foregoing
      undertakings may be unenforceable for any reason, TransCore agrees to make
      the maximum contribution to the payment and satisfaction of indemnified
      liabilities set forth in this Section 15.1 which is permissible under
      applicable law. This indemnity and agreement to defend and hold harmless
      shall survive the termination of this Agreement or any other circumstances
      which might otherwise constitute a legal or equitable release or
      discharge, in whole or in part, of TransCore under this Agreement.

            SECTION 16. MISCELLANEOUS

            16.1. No Third Party Beneficiaries. The parties do not intend the
      benefits of this Agreement to inure to any third party. Notwithstanding
      anything contained herein or any conduct or course of conduct by any or
      all of the parties hereto, or their respective affiliated companies,
      agents or employees, before or after signing this Agreement, this
      Agreement shall not be construed as creating any rights, claims or causes
      of action against AIG Highstar or TCC, or any of their respective
      directors, officers, agents or employees in favor of any of creditors of
      TransCore.

            16.2. Survival of Representations and Warranties. All
      representations, warranties, covenants and agreements made in this
      Agreement and in any certificates delivered pursuant thereto shall survive
      the execution and delivery of this Agreement.

            16.3. Participations. AIG Highstar reserves the absolute right to
      assign all or any portion of its interests in this Agreement or to
      participate with other institutions in this Agreement on such terms and at
      such times as AIG Highstar may determine from time to time, all without
      any consent thereto or notice thereof by or to TCC; provided, however,
      that no assignment or participation of this Agreement by AIG Highstar
      shall relieve AIG Highstar of any liability hereunder.

            16.4. Miscellaneous. No failure by a party to comply with any
      provision or provisions of this Agreement, and no waiver on the part of
      any party in exercising any rights hereunder, shall operate as a waiver of
      any rights of such party. Tardiness in enforcing any provision hereof
      shall not be set up as a waiver by a party of any of its rights hereunder
      and all covenants on the part of the parties hereunder to be kept and
      performed may be enforced at any time.

            16.5. Notices. All notices and other communications shall have been

      between the provisions of this Agreement and any other Transaction
      Document or any other document executed and/or delivered in connection
      with this Agreement, the provisions of this Agreement shall prevail,
      notwithstanding any provision in any other document to the effect that
      such other document shall be deemed controlling.

            16.7. Binding Effect. This Agreement shall be binding upon and inure
      to the benefit of the parties hereto and their respective successors and
      assigns, except that neither TransCore or TCC may assign nor transfer

            16.8. Construction. This Agreement, and the rights and obligations
      of the parties hereunder, shall be governed by and construed and
      interpreted in accordance with, the domestic internal laws of the State of

      any such prohibition or unenforceability in any jurisdiction shall not
      invalidate or render unenforceable such provision in any other
      jurisdiction.

            16.10. Dispute Resolution.

                  (a)   Any and all disputes arising out of or in connection

            shall be settled by negotiation between the parties set forth in
            Section 16.5 of this Agreement, or their designee. To initiate
            Dispute resolution, a party shall send written notice describing the
            dispute to the other party ("Dispute Notice"). If the parties are

            administered by the American Arbitration Association ("AAA") under
            its Commercial Mediation Rules, before resorting to arbitration or
            any other form of dispute resolution.

                  (b)   In the event any Dispute among the parties is not
            resolved under the

                                       27

<PAGE>

            process set forth in paragraph (a) of this Agreement:

                        A.    The Dispute shall be submitted by the parties to
arbitration under the Commercial Arbitration Rules of the American Arbitration
Association ("AAA Rules"). Judgment rendered by the arbitrators may be entered

                        B.    Apply the substantive law of the State of New
York;

                        C.    Be conducted in New York, New York unless the
parties agree upon a different location;

                        D.    Be conducted by one neutral arbitrator selected by

exchange of information by the parties, including, without limitation,
production of requested documents, exchanging of summaries of testimony of
proposed witnesses and examination by deposition of parties, limited to no
longer than 6 hours per deponent absent agreement of the parties. This
pre-hearing exchange of information shall be governed by the Federal Rules of
Civil Procedure.

                        F.    Each party shall bear its individual costs, such
as, but not limited to, travel, to the arbitration, witness fees and expenses,
and legal representation at the arbitration. All other expenses of the
arbitration shall be borne equally by the parties;

                        G.    The arbitrator's award shall be in writing and
shall specify the factual and legal bases for the award;

                        H.    The arbitrator will have no authority to issue an
injunction or to award punitive or other damages not measured by the prevailing
party's actual damages and may not, in any event, make any ruling, finding, or
award that does not conform to the terms and conditions of this Agreement and
any other related contract.

                        I.    Each party to this Agreement agrees to maintain
the confidentiality of any mediation or arbitration proceedings, including the
existence of any such proceeding and all aspects of matters considered therein,
to the maximum extent permitted by law. In the event of any court or other
public proceeding involving matters subject to an arbitration or mediation, the
parties agree to take all procedural actions to maintain the confidentiality of
documents relating to the arbitration or mediation.

                  (c)   Appeal Rights:

                                       28

arbitration was held.

                              ii.   if the award contains material errors of
                                    applicable law; or

                              iii.  if the award is arbitrary or capricious.


                        D.    The appellate arbitrator may render a final
decision on the appeal or remand the matter for further proceedings by the
arbitrator.

                  (d)   Upon the application of any party, and whether or not an
            arbitration proceeding has been initiated, all courts having
            jurisdiction are authorized to:

                        A.    Issue and enforce in any lawful manner such
temporary restraining orders, preliminary injunctions and other interim measures
of relief as may be necessary to prevent harm to a party's interests or as
otherwise may be appropriate pending the conclusion of arbitration proceedings
pursuant to this Agreement; and/or

                        B.    Enter and enforce in any lawful manner such
judgment for permanent equitable relief as may be necessary to prevent harm to a

            16.12. Counterparts. This Agreement may be executed in any number of
      counterparts with the same effect as if the signatures thereto and hereto

            16.13. Further Actions. Each party shall execute and deliver such
      documents and instruments, and take such other actions, as the other
      parties deem necessary to consummate the transactions described in this

      requested information or certification as an Issuer may reasonably
      request. In addition, upon reduction of the AIG Highstar Payment
      Commitment from $20 million to $4 million, TransCore shall take all
      actions necessary to obtain Additional Letters of Credit to secure TCC
      Obligations that are no longer secured by the AIG Highstar Payment
      Commitment.

      I, Claudia F. Wiegand, hereby certify that I am the duly appointed
Executive Vice President of TRANSCORE HOLDINGS, INC., a Delaware corporation
(the "Corporation"), and I am delivering this Certificate to AIG HIGHSTAR
CAPITAL, L.P. ("AIG Highstar"), in my capacity as Executive Vice President of
the Corporation pursuant to that certain Irrevocable Funding, Warrant Purchase
and Reimbursement Agreement dated October __, 2002, by and among the
Corporation, TransCore Credit Corporation and AIG Highstar (the "Irrevocable
Funding Agreement") and hereby certify to AIG Highstar that:

            1. TransCore has discovered accounting irregularities at the time of
            the acquisition of Viastar Holdings, Inc. ("Viastar") and for the
            fiscal years ending January 31, 2001 and January 31, 2002 in the
            accounts receivable, accounts payable, cash and possibly other
            balance sheet accounts of Viastar (the "Irregularities"). TransCore,
            for accounting purposes, has now treated Viastar as a discontinued
            operation and incurred a charge of approximately $40 million (the
            "Discontinued Operations Charge"). The Senior Lender and Purchasers
            (as defined under the Note Purchase Agreement) have waived any
            Default or Event of Default caused by the breach of any
            representation or warranty made in either the Credit Agreement or
            Sub-Debt Note Purchase Agreements, as the case may be, to the extent
            such breach is due solely to the Irregularities or the Discontinued
            Operations Charge.

      IN WITNESS WHEREOF, the undersigned has executed this Officer's
Certificate this _st day of October, 2002.
