                                    RECITALS

         A. InPhonic and Bank are parties to the Original Loan Documents,
pursuant to which Bank agreed to make loans to InPhonic upon the terms and
conditions contained therein.

         B. SimIpc is a wholly-owned subsidiary of InPhonic.

         C. Borrowers have requested and Bank has agreed to amend and restate
the Original Loan Documents, subject to the terms and conditions hereinafter set
forth and the documents to be executed in connection herewith.

                                    AGREEMENT

         The parties agree as follows:

         1. Definitions And Construction.

            1.1  Definitions. As used in this Agreement, the following terms
shall have the definitions set forth on Exhibit A.

            1.2  Accounting Terms. All accounting terms not specifically defined
on Exhibit A shall be construed in accordance with GAAP and all calculations
shall be made in accordance with GAAP. The term "financial statements" shall
include the accompanying notes and schedules.

         2. Loan And Terms Of Payment.

            2.1  Credit Extensions.

                 (a)  Borrowers promise to pay to Bank, in lawful money of the
United States of America, the aggregate unpaid principal amount of all Credit
Extensions made by Bank to Borrowers, together with interest on the unpaid
principal amount of such Credit Extensions at rates in accordance with the terms

               (b)   Revolving Advances.

                     (i)   Subject to and upon the terms and conditions of this
Agreement (1) Borrowers may request Advances in an aggregate outstanding amount
not to exceed the amount of the Committed Revolving Line at any one time;
provided, however, that at any time that the aggregate outstanding amount of
Advances exceeds $2,000,000 (the "Non-Formula Amount"), the aggregate
outstanding amount of Advances shall not exceed the lesser of (i) the Committed
Revolving Line or (ii) the Borrowing Base; provided, further that, if at any
time or from time to time, the aggregate outstanding amount of Advances exceeds
the Non-Formula and, thereafter, the aggregate outstanding amount of Advances is
reduced below the Non-Formula Amount, for so long as the aggregate outstanding
amount of Advances is less than the Non-Formula Amount, the Advances shall not
be subject to the Borrowing Base. Amounts borrowed pursuant to this Section
2.1(b) may be repaid and reborrowed at any time prior to the Revolving Maturity
Date, at which time all Advances under this Section 2.1(b), together with all
accrued and unpaid interest thereon, shall be immediately due and payable.
Borrowers may prepay any Advances without penalty or premium.

                     (ii)  Whenever any Borrower desires an Advance, such
Borrower will notify Bank by facsimile transmission or telephone no later than
3:00 p.m. Eastern time, on the Business Day that the Advance is to be made. Each
such notification shall be promptly confirmed by a Payment/Advance Form in
substantially the form of Exhibit C. Bank is authorized to make Advances under
this Agreement, based upon instructions received from a Responsible Officer or a
designee of a Responsible Officer, or without instructions if in Bank's
discretion such Advances are necessary to meet Obligations which have become due
and remain unpaid. Bank shall be entitled to rely on any telephonic notice given
by a person who Bank reasonably believes to be a Responsible Officer or a
designee thereof, and Borrowers shall indemnify and hold Bank harmless for any
damages or loss suffered by Bank as a result of such reliance. Bank will credit
the amount of Advances made under this Section 2.1(b) to Borrowers' deposit
account.

                     (iii) As a condition precedent to an Advance causing
aggregate Advances to exceed the Non-Formula Amount, Bank shall conduct an audit
of each Borrower's Accounts, at each Borrower's reasonable expense, the results
of which must be satisfactory to Bank.

               (c)   Equipment Advances.

                     (i)   Subject to and upon the terms and conditions of this
Agreement, on the date hereof and at any time from the date hereof through the
Tranche B Availability End Date, the Tranche C Availability End Date, the
Tranche D Availability End Date and the Tranche E Availability End Date, as
applicable, Bank agrees to make advances to Borrowers in five tranches, Tranche
A (comprised of Tranche A-1 and Tranche A-2), Tranche B, Tranche C, Tranche D
and Tranche E (each an "Equipment Advance" and collectively, the "Equipment

Closing Date against invoices for equipment, furniture and software specifically
approved in advance by Bank and, unless otherwise approved in writing by Bank,
in its sole and absolute discretion, dated on or after the date ninety (90) days
prior to the Closing Date. Bank shall make

                                       2.

<PAGE>

                     (i)  Subject to the availability under the Committed
Revolving Line and in reliance on the representations and warranties of
Borrowers set forth herein, at any time and from time to time from the date
hereof through the Business Day immediately prior to the Revolving Maturity
Date, Bank shall issue for the account of Borrowers such standby and commercial
letters of credit (each, a "Letter of Credit" and collectively, "Letters of
Credit") as Borrowers may request, which request shall be made by delivering to
Bank a duly executed letter of credit application on Bank's standard form
substantially similar to Exhibit F attached hereto; provided, however, that the
outstanding and undrawn amounts under all such Letters of Credit (a) shall not
at any time exceed $500,000 and (b) shall be deemed to constitute Advances for
the purpose of calculating availability under the Revolving Facility. Unless
Borrowers shall have deposited with Bank cash collateral in an amount sufficient
to cover all undrawn amounts under each such Letter of Credit and Bank shall
have agreed in writing, no Letter of Credit shall have an expiration date that
is later than the Revolving Maturity Date. All Letters of Credit shall be in
form and substance acceptable to Bank in its sole discretion and shall be
subject to the terms and conditions of Bank's form application and letter of
credit agreement. Borrowers will pay any standard issuance and other fees that
Bank notifies Borrowers will be charged for issuing and processing Letters of
Credit for Borrowers.

                     (ii) As of the date hereof, there is an outstanding standby
letter of credit in the amount of $202,500 issued by Bank for the account of
InPhonic (the "Existing Letter of Credit"). The Existing Letter of Credit shall
be deemed to constitute a Letter of Credit hereunder and the amount of the
Existing Letter of Credit shall be deemed to constitute (a) Revolving Advances
for the purpose of calculating availability under the Revolving Facility and (b)
a Letter of Credit for purposes of determining whether outstanding and undrawn
Letters of Credit exceed the $500,000 sublimit.

          2.2  Overadvances. If the aggregate amount of the outstanding Advances
exceeds the amounts permitted to be borrowed under Section 2.1(b)(i) hereof at
any time, Borrowers shall immediately pay to Bank, in cash, the amount of such
excess.

          2.3  Interest Rates, Payments, and Calculations.

               (a)   Interest Rates.

                     (i)  Advances. Except as set forth in Section 2.3(b), the
Advances shall bear interest, on the outstanding daily balance thereof, at a
rate equal to 0.6% above the Prime Rate.

                     (ii) Equipment Advances. Except as set forth in Section
2.3(b), the Equipment Advances shall bear interest, on the outstanding daily
balance thereof, at a rate equal to 1.5% above the Prime Rate.

               (b)   Late Fee; Default Rate. If any payment is not made within
ten (10) days after the date such payment is due, Borrowers shall pay Bank a
late fee equal to the lesser of (i) 5% of the amount of such unpaid amount or
(ii) the maximum amount permitted to be charged under applicable law. All
Obligations shall bear interest, from and after the occurrence and during the
continuance of an Event of Default, at a rate equal to five percentage

                                       6.

<PAGE>

points above the interest rate applicable immediately prior to the occurrence of
the Event of Default.

                     (c) Payments. Interest hereunder shall be due and payable
on the first calendar day of each month during the term hereof. Bank shall, at
its option, charge such interest, all Bank Expenses, and all Periodic Payments
against any of Borrowers' deposit accounts or against the Committed Revolving
Line, in which case those amounts shall thereafter accrue interest at the rate
then applicable hereunder. Any interest not paid when due shall be compounded by
becoming a part of the Obligations, and such interest shall thereafter accrue
interest at the rate then applicable hereunder.

                     (d) Computation. In the event the Prime Rate is changed
from time to time hereafter, the applicable rate of interest hereunder shall be
increased or decreased, effective as of the day the Prime Rate is changed, by an
amount equal to such change in the Prime Rate. All interest chargeable under the
Loan Documents shall be computed on the basis of a 360 day year for the actual
number of days elapsed.

              2.4    Crediting Payments. Prior to the occurrence of an Event of
Default, Bank shall credit a wire transfer of funds, check or other item of
payment to such deposit account or Obligation as Borrowers specify. After the
occurrence of an Event of Default, the receipt by Bank of any wire transfer of
funds, check, or other item of payment shall be immediately applied to
conditionally reduce Obligations, but shall not be considered a payment on
account unless such payment is of immediately available federal funds or unless
and until such check or other item of payment is honored when presented for
payment. Notwithstanding anything to the contrary contained herein, any wire
transfer or payment received by Bank after 12:00 noon Eastern time shall be
deemed to have been received by Bank as of the opening of business on the
immediately following Business Day. Whenever any payment to Bank under the Loan
Documents would otherwise be due (except by reason of acceleration) on a date
that is not a Business Day, such payment shall instead be due on the next
Business Day, and additional fees or interest, as the case may be, shall accrue
and be payable for the period of such extension.

              2.5    Fees. Borrowers shall pay to Bank the following:

                     (a) Facility Fee. On the Closing Date, a Facility Fee equal
to $12,500, which shall be nonrefundable;

                     (b) Bank Expenses. On the Closing Date, all Bank Expenses
incurred through the Closing Date, including reasonable attorneys' fees and
expenses and, after the Closing Date, all Bank Expenses, including reasonable
attorneys' fees and expenses, as and when they become due.

              2.6    Term. This Agreement shall become effective on the Closing
Date and, subject to Section 12.7, shall continue in full force and effect for a
term ending on the Equipment Maturity Date.

        3.    Conditions Of Loans.

                                       7.

<PAGE>

              3.1   Conditions Precedent to Initial Credit Extension. The
obligation of Bank to make the initial Credit Extension is subject to the
condition precedent that Bank shall have received, in form and substance
satisfactory to Bank, the following:

                    (a)  this Agreement;

                    (b)  an officer's certificate of each Borrower with respect
to incumbency and resolutions authorizing the execution and delivery of this
Agreement;

                    (c)  financing statements and amendments as Bank deems
necessary or appropriate;

                    (d)  an intellectual property security agreement for each
Borrower;

                    (e)  an agreement to provide insurance;

                    (f)  duly executed deposit and/or investment account control
agreements as required by Bank, in form and substance acceptable to Bank;

                    (g)  payment of the fees and Bank Expenses then due
specified in Section 2.5;

                    (h)  current financial statements in accordance with Section
6.2; and

                    (i)  such other documents, and completion of such other
matters, as Bank may reasonably deem necessary or appropriate.

              3.2   Conditions Precedent to All Credit Extensions. The
obligation of Bank to make each Credit Extension, including the initial Credit
Extension, is further subject to the following conditions:

                    (a)  timely receipt by Bank of the Payment/Advance Form as
provided in Section 2.1; and

                    (b)  the representations and warranties contained in Section
5 shall be true and correct in all material respects on and as of the date of
such Payment/Advance Form and on the effective date of each Credit Extension as
though made at and as of each such date, and no Event of Default shall have
occurred and be continuing, or would exist after giving effect to such Credit
Extension (provided, however, that those representations and warranties
expressly referring to another date shall be true, correct and complete in all
material respects as of such date). The making of each Credit Extension shall be
deemed to be a representation and warranty by each Borrower on the date of such
Credit Extension as to the accuracy of the facts referred to in this Section
3.2.

        4.    Creation Of Security Interest.

              4.1   Grant of Security Interest. Each Borrower grants and pledges
to Bank a continuing security interest in all presently existing and hereafter
acquired or arising Collateral to

                                       8.

<PAGE>

secure prompt repayment of any and all Obligations and to secure prompt
performance by each Borrower of each of its covenants and duties under the Loan
Documents. Except as set forth in the Schedule, such security interest
constitutes a valid, first priority security interest in the presently existing
Collateral, and will constitute a valid, first priority security interest in
later-acquired Collateral. Notwithstanding any termination, Bank's Lien on the
Collateral shall remain in effect for so long as any Obligations are
outstanding.

              4.2   Delivery of Additional Documentation Required. Each Borrower
shall from time to time execute and deliver to Bank, at the request of Bank, all
Negotiable Collateral, all financing statements and other documents that Bank
may reasonably request, in form satisfactory to Bank, to perfect and continue
perfected Bank's security interests in the Collateral and in order to fully
consummate all of the transactions contemplated under the Loan Documents.

              4.3   Right to Inspect. Bank (through any of its officers,
employees, or agents) shall have the right, upon reasonable prior notice, from
time to time during Borrowers' usual business hours but no more than twice a
year (unless an Event of Default has occurred and is continuing), to inspect
Borrowers' Books and to make copies thereof and to check, test, and appraise the
Collateral in order to verify Borrowers' financial condition or the amount,
condition of, or any other matter relating to, the Collateral. Bank acknowledges
and agrees that any information furnished to or obtained by Bank pursuant to
this Section 4.3 shall be subject to the confidentiality provisions set forth in
Section 12.8 herein.

         5.   Representations And Warranties.

              Each Borrower represents and warrants as follows:

              5.1   Due Organization and Qualification. Each Borrower and each
Subsidiary is a corporation duly existing under the laws of its state of
incorporation and qualified and licensed to do business in any state in which
the conduct of its business or its ownership of property requires that it be so
qualified, except where the failure to do so could not reasonably be expected to
cause a Material Adverse Effect.

              5.2   Due Authorization; No Conflict. The execution, delivery, and
performance of the Loan Documents are within Borrowers' powers, have been duly
authorized, and are not in conflict with nor constitute a breach of any
provision contained in such Borrower's Certificate of Incorporation or Bylaws,
nor will they constitute an event of default under any material agreement by
which such Borrower is bound. Neither Borrower is in default under any agreement
by which it is bound, which default could have a Material Adverse Effect.

              5.3   Collateral. Each Borrower has good title to the Collateral,
free and clear of Liens, except for Permitted Liens. The Eligible Accounts are
bona fide existing obligations. The property giving rise to such Eligible
Accounts has been delivered to the account debtor or its agent for immediate
shipment to and unconditional acceptance by the account debtor. Neither Borrower
has received notice of any actual or imminent Insolvency Proceeding of any
account debtor whose accounts are included in any Borrowing Base Certificate as
an Eligible Account.

                                       9.

All Inventory is in all material respects of good and marketable quality, free
from all material defects, except for Inventory for which adequate reserves have
been made.

              5.4   Intellectual Property Collateral. Each Borrower is the sole
owner of its Intellectual Property Collateral, except for Licenses granted by
such Borrowers to its customers in the ordinary course of business. Each of the
Copyrights, Trademarks and Patents is valid and enforceable, and no part of the
Intellectual Property Collateral has been judged invalid or unenforceable, in
whole or in part, and, to Borrowers' knowledge, no claim has been made that any
part of the Intellectual Property Collateral violates the rights of any third
party except to the extent such claim could not reasonably be expected to cause
a Material Adverse Effect. Except as set forth in the Schedule, Borrowers'
rights as licensees of intellectual property do not give rise to more than 5% of
their gross revenue in any given month, including without limitation revenue
derived from the sale, licensing, rendering or disposition of any product or
service.

              5.5   Name; Location of Chief Executive Office. Except as
disclosed in the Schedule, Borrowers have not done business under any name other
than those specified on the signature page hereof. The chief executive office of
each Borrower is located at the addresses indicated in Section 10 hereof.

              5.6   Litigation. Except as set forth in the Schedule, there are
no actions or proceedings pending by or against any Borrower or any Subsidiary
before any court or administrative agency in which a likely adverse decision
could reasonably be expected to have a Material Adverse Effect, or a material
adverse effect on Borrowers' interest or Bank's security interest in the
Collateral.

              5.7   No Material Adverse Change in Financial Statements. All
consolidated financial statements related to any Borrower and any Subsidiary
that are delivered by Borrowers to Bank fairly present in all material respects
Borrowers' consolidated financial condition as of the date thereof and
Borrowers' consolidated results of operations for the period then ended. There
has not been a material adverse change in the consolidated financial condition
of Borrowers since the date of the most recent of such financial statements
submitted to Bank.

              5.8   Solvency, Payment of Debts. Each Borrower is able to pay its
debts (including trade debts) as they mature; the fair saleable value of
Borrowers' assets (including goodwill minus disposition costs) exceeds the fair
value of their liabilities; and Borrowers are not left with an unreasonably
small amount of capital after the transactions contemplated by this Agreement
relative to the Borrowers' business and operations.

              5.9   Compliance with Laws and Regulations. Each Borrower and each
Subsidiary have met the minimum funding requirements of ERISA with respect to
any employee benefit plans subject to ERISA. No event has occurred resulting
from any Borrowers' failure to comply with ERISA that is reasonably likely to
result in such Borrower's incurring any liability that could have a Material
Adverse Effect. Neither Borrower is an "investment company" or a company
"controlled" by an "investment company" within the meaning of the Investment
Company Act of 1940. Neither Borrower is engaged principally, or as one of the
important activities, in the business of extending credit for the purpose of
purchasing or carrying margin stock (within the meaning of Regulations T and U
of the Board of Governors of the Federal

                                       10.

<PAGE>

Reserve System). Each Borrower has complied in all material respects with all
the provisions of the Federal Fair Labor Standards Act. Each Borrower is in
compliance with all environmental laws, regulations and ordinances except where
the failure to comply is not reasonably likely to have a Material Adverse
Effect. Neither Borrower has violated any statutes, laws, ordinances or rules
applicable to it, violation of which could have a Material Adverse Effect. Each
Borrower and each Subsidiary have filed or caused to be filed all tax returns
required to be filed, and have paid, or have made adequate provision for the
payment of, all taxes reflected therein except those being contested in good
faith with adequate reserves under GAAP.

              5.10  Subsidiaries. Neither Borrower owns any stock, partnership
interest or other equity securities of any Person, except for Permitted
Investments.

              5.11  Government Consents. Each Borrower and each Subsidiary have
obtained all consents, approvals and authorizations of, made all declarations or
filings with, and given all notices to, all governmental authorities that are
necessary for the continued operation of such Borrowers' business as currently
conducted, except where the failure to do so could not reasonably be expected to
cause a Material Adverse Effect.

              5.12  Inbound Licenses. Except as disclosed on the Schedule,
neither Borrower is party to, nor is bound by, any license or other agreement
that prohibits or otherwise restricts such Borrower from granting a security
interest in such Borrower's interest in such license or agreement or any other
property.

              5.13  Full Disclosure. No representation, warranty or other
statement made by any Borrower in any certificate or written statement furnished
to Bank taken together with all such certificates and written statements
furnished to Bank contains any untrue statement of a material fact or omits to
state a material fact necessary in order to make the statements contained in
such certificates or statements not misleading, it being recognized by Bank that
the projections and forecasts provided by Borrowers in good faith and based upon
reasonable assumptions are not to be viewed as facts and that actual results
during the period or periods covered by any such projections and forecasts may
differ from the projected or forecasted results.

        6.    Affirmative Covenants.

              Each Borrower covenants that, until payment in full of all
outstanding Obligations, and for so long as Bank may have any commitment to make
a Credit Extension hereunder, each Borrower shall do all of the following:

              6.1   Good Standing and Government Compliance. Each Borrower shall
maintain its and each of its Subsidiaries' corporate existence in its
jurisdiction of incorporation and maintain qualification in each jurisdiction in
which the failure to so qualify could have a Material Adverse Effect. Each
Borrower shall meet, and shall cause each Subsidiary to meet, the minimum
funding requirements of ERISA with respect to any employee benefit plans subject
to ERISA. Each Borrower shall comply, and shall cause each Subsidiary to comply,
with all statutes, laws, ordinances and government rules and regulations to
which it is subject, and shall maintain, and shall cause each of its
Subsidiaries to maintain, in force all licenses, approvals and agreements, the
loss of which or failure to comply with which could have a Material Adverse

                                       11.

<PAGE>

Effect, or a material adverse effect on the Collateral or the priority of Bank's
Lien on the Collateral.

               6.2  Financial Statements, Reports, Certificates. Each Borrower
shall deliver to Bank: (a) as soon as available, but in any event within 30 days
after the end of each calendar month, a company prepared consolidated balance
sheet and income statement covering such Borrower's consolidated operations
during such period, in a form acceptable to Bank and certified by a Responsible
Officer; (b) as soon as available, but in any event within 120 days after the
end of such Borrower's fiscal year, audited consolidated financial statements of

such financial statements of an independent certified public accounting firm
reasonably acceptable to Bank; (c) if applicable, copies of all statements,
reports and notices sent or made available generally by such Borrower to its
security holders or to any holders of Subordinated Debt and all reports on Forms
10-K and 10-Q filed with the Securities and Exchange Commission; (d) promptly
upon receipt of notice thereof, a report of any legal actions pending or
threatened against such Borrower or any Subsidiary that could result in damages
or costs to such Borrower or any Subsidiary of $100,000 or more; (e) such
budgets, sales projections, operating plans or other financial information
generally prepared by such Borrower in the ordinary course of business as Bank
may reasonably request from time to time; and (f) within 30 days of the last day
of each fiscal quarter, a report signed by such Borrower, in form reasonably
acceptable to Bank, listing any applications or registrations that Borrowers
have made or filed in respect of any Patents, Copyrights or Trademarks and the
status of any outstanding applications or registrations, as well as any material
change in such Borrower's Intellectual Property Collateral, including but not
limited to any subsequent ownership right of such Borrower in or to any
Trademark, Patent or Copyright not specified in Exhibits A, B, and C of the
Intellectual Property Security Agreement delivered to Bank by such Borrower in
connection with this Agreement.

                    (a) Prior to the aggregate Advances exceeding the
Non-Formula Amount and within 20 days after the last day of each month that
aggregate Advances exceed the Non-Formula Amount, Borrowers shall deliver to
Bank a Borrowing Base Certificate signed by a Responsible Officer in
substantially the form of Exhibit D hereto, together with aged listings of
accounts receivable and accounts payable and evidence of credit ratings for
publicly traded account debtors to the extent applicable.

                    (b) Within 30 days after the last day of each month,
Borrowers shall deliver to Bank with the monthly financial statements a
Compliance Certificate signed by a Responsible Officer in substantially the form
of Exhibit E hereto.

                    (c) Bank shall have a right from time to time hereafter to
audit Borrowers' Accounts and appraise Collateral at Borrowers' reasonable
expense, provided that such audits will be conducted no more often than twice
every 12 months unless an Event of Default has occurred and is continuing.

               6.3  Inventory; Returns. Each Borrower shall keep all Inventory
in good and marketable condition, free from all material defects except for
Inventory for which adequate reserves have been made. Returns and allowances, if
any, as between any Borrower and its

                                       12.

<PAGE>

account debtors shall be on the same basis and in accordance with the usual
customary practices of such Borrower, as they exist on the Closing Date. Each
Borrower shall promptly notify Bank of all returns and recoveries and of all
disputes and claims involving more than $100,000.

               6.4  Taxes. Each Borrower shall make, and cause each Subsidiary
to make, due and timely payment or deposit of all material federal, state, and
local taxes, assessments, or contributions required of it by law, including, but
not limited to, those laws concerning income taxes, F.I.C.A., F.U.T.A. and state
disability, and will execute and deliver to Bank, on demand, proof satisfactory
to Bank indicating that such Borrower or a Subsidiary has made such payments or
deposits and any appropriate certificates attesting to the payment or deposit
thereof; provided that Borrowers or a Subsidiary need not make any payment if
the amount or validity of such payment is contested in good faith by appropriate
proceedings and is reserved against (to the extent required by GAAP) by such
Borrower.

               6.5  Insurance.

                    (a) Each Borrower, at its expense, shall keep the Collateral
insured against loss or damage by fire, theft, explosion, sprinklers, and all
other hazards and risks, and in such amounts, as ordinarily insured against by
other owners in similar businesses conducted in the locations where such
Borrowers' business is conducted on the date hereof. Each Borrower shall also
maintain liability and other insurance in amounts and of a type that are
customary to businesses similar to such Borrower's.

                    (b) All such policies of insurance shall be in such form,
with such companies, and in such amounts as reasonably satisfactory to Bank. All
policies of property insurance shall contain a lender's loss payable
endorsement, in a form satisfactory to Bank, showing Bank as an additional loss
payee, and all liability insurance policies shall show Bank as an additional
insured and specify that the insurer must give at least 20 days notice to Bank
before canceling its policy for any reason. Upon Bank's request, Borrowers shall
deliver to Bank certified copies of the policies of insurance and evidence of
all premium payments. If no Event of Default has occurred and is continuing,
proceeds payable under any casualty policy will, at Borrowers' option, be
payable to Borrowers to replace the property subject to the claim, provided that
any such replacement property shall be deemed Collateral in which Bank has been
granted a first priority security interest. If an Event of Default has occurred
and is continuing, all proceeds payable under any such policy shall, at Bank's
option, be payable to Bank to be applied on account of the Obligations.

               6.6  Primary Depository. Each Borrower shall maintain not less
than 50% of its cash with Bank. The remainder of each Borrower's cash may be
maintained at third party financial institutions only upon the execution and
delivery of account control agreements satisfactory to Bank.

               6.7  Financial Covenants. Borrowers shall maintain, on a
consolidated basis, as of the last day of each calendar month unless stated
otherwise:

Liabilities of at least 1.50 to 1.00.

               6.8  Registration of Intellectual Property Rights.

                    (a) Each Borrower shall register or cause to be registered
on an expedited basis (to the extent not already registered) with the United
States Patent and Trademark Office or the United States Copyright Office, as
applicable: (i) those intellectual property rights listed on Exhibits A, B and C
to the Intellectual Property Security Agreement delivered to Bank by Borrowers
in connection with this Agreement, within 30 days of the date of this Agreement,
(ii) all registrable intellectual property rights Borrowers have developed as of
the date of this Agreement but heretofore failed to register, within 30 days of
the date of this Agreement, and (iii) those additional intellectual property
rights developed or acquired by Borrowers from time to time in connection with
any product, prior to the sale or licensing of such product to any third party,
and prior to Borrowers' use of such product (including without limitation major
revisions or additions which significantly improve the functionality of the
intellectual property rights listed on such Exhibits A, B and C). Borrowers
shall give Bank notice of all such applications or registrations.

                    (b) Each Borrower shall execute and deliver such additional
instruments and documents from time to time as Bank shall reasonably request to
perfect Bank's security interest in the Intellectual Property Collateral.

                    (c) Each Borrower shall (i) protect, defend and maintain the
validity and enforceability of the Trademarks, Patents and Copyrights, (ii) use
its best efforts to detect infringements of the Trademarks, Patents and
Copyrights and promptly advise Bank in writing of material infringements
detected and (iii) not allow any material Trademarks, Patents or Copyrights to
be abandoned, forfeited or dedicated to the public without the written consent
of Bank, which shall not be unreasonably withheld.

                    (d) Bank may audit Borrowers' Intellectual Property
Collateral to confirm compliance with this Section 6.8, provided such audit may
not occur more often than twice per year, unless an Event of Default has
occurred and is continuing. Bank shall have the right, but not the obligation,
to take, at Borrowers' sole expense, any actions that Borrowers are required
under this Section 6.8 to take but which Borrowers fail to take, after 15 days'
notice to Borrowers. Borrowers shall reimburse and indemnify Bank for all
reasonable costs and reasonable expenses incurred in the reasonable exercise of
its rights under this Section 6.8.

                                       14.

<PAGE>

              6.9  Consent of Inbound Licensors. Prior to entering into or
becoming bound by any license or agreement that is reasonably likely to have a
material impact on Borrowers' business or financial condition, Borrowers shall:
(i) provide written notice to Bank of the material terms of such license or
agreement with a description of its likely impact on Borrowers' business or
financial condition; and (ii) take such steps as Bank requests to obtain the
consent of, or waiver by, any person whose consent or waiver is necessary for
Borrowers' interest in such licenses or contract rights to be deemed Collateral
and for Bank to have a security interest in it that might otherwise be
restricted by the terms of the applicable license or agreement, whether now
existing or entered into in the future.

              6.10 Further Assurances. At any time and from time to time
Borrowers shall execute and deliver such further instruments and take such
further action as may reasonably be requested by Bank to effect the purposes of
this Agreement.

              6.11 Conversion of Revenue Recognition Policy. No later than April
30, 2002, Bank must receive reasonable verbal assurance from any "Big 5"
accounting firm that Borrowers' conversion to a non-deferral based revenue
recognition policy is acceptable and based on GAAP, and that the reserve
estimate is reasonable.

         7.   Negative Covenants.

              Each Borrower covenants and agrees that, so long as any credit
hereunder shall be available and until payment in full of the outstanding
Obligations or for so long as Bank may have any commitment to make any Credit
Extensions, neither Borrower will do any of the following without Bank's prior
written consent, which shall not be unreasonably withheld, conditioned or
delayed:

              7.1  Dispositions. Convey, sell, lease, transfer or otherwise
dispose of (collectively, to "Transfer"), or permit any of its Subsidiaries to
Transfer, all or any part of its business or property, other than Permitted
Transfers.

              7.2  Change in Business; Change in Control or Executive Office or
Jurisdiction of Incorporation. Engage in any business, or permit any of its
Subsidiaries to engage in any business, other than or reasonably related or
incidental to the businesses currently engaged in by Borrowers. Neither Borrower
will have a Change in Control and will not, without 30 days prior written
notification to Bank, relocate its chief executive office or change it
jurisdiction of incorporation.

              7.3  Mergers or Acquisitions. Merge or consolidate, or permit any
of its Subsidiaries to merge or consolidate, with or into any other Person
(other than mergers or consolidations of a Subsidiary into another Subsidiary or
into Borrowers), or acquire, or permit any of its Subsidiaries to acquire, all
or substantially all of the capital stock or property of another Person (each of
the above transactions referred to as an "Acquisition"), except where (i) such
Acquisitions, together with all Joint Venture Investments, do not in the
aggregate exceed $500,000 in cash, stock and other consideration during the term
of this Agreement, (ii) no Event of Default has occurred, is continuing or would
exist after giving effect to such transaction and

                                       15.

<PAGE>

(iii) such merger constitutes a Permitted Investment. Notwithstanding the above,
SimIpc shall be permitted to acquire the assets of Simplexity, Inc.

              7.4 Indebtedness. Create, incur, assume or be or remain liable
with respect to any Indebtedness, or permit any Subsidiary so to do, other than
Permitted Indebtedness.

              7.5 Encumbrances. Create, incur, assume or allow any Lien with
respect to any of its property, or assign or otherwise convey any right to
receive income, including the sale of any Accounts, or permit any of its

Person that such Borrower in the future will refrain from creating, incurring,
assuming or allowing any Lien with respect to any of Borrowers' property.

              7.6 Distributions. Pay any dividends or make any other
distribution or payment on account of or in redemption, retirement or purchase
of any capital stock, except that such Borrower may repurchase the stock of
former employees pursuant to stock repurchase agreements as long as an Event of
Default does not exist prior to such repurchase or would not exist after giving
effect to such repurchase.

              7.7 Investments. Directly or indirectly acquire or own, or make
any Investment in or to any Person, or permit any of its Subsidiaries so to do,
other than Permitted Investments.

              7.8 Transactions with Affiliates. Directly or indirectly enter
into or permit to exist any material transaction with any Affiliate of any
Borrower except for transactions that are in the ordinary course of Borrowers'
business, upon fair and reasonable terms that are no less favorable to such
Borrower than would be obtained in an arm's length transaction with a
non-affiliated Person.

              7.9 Subordinated Debt. Make any payment in respect of any
Subordinated Debt, or permit any of its Subsidiaries to make any such payment,
except in compliance with the terms of such Subordinated Debt, or amend any
provision contained in any documentation relating to the Subordinated Debt
without Bank's prior written consent.

              7.10 Inventory and Equipment. Store the Inventory or the Equipment
with a bailee, warehouseman, or similar party unless Bank has received a pledge
of the warehouse receipt covering such Inventory. Except for Inventory sold in
the ordinary course of business and except for such other locations as Bank may
approve in writing, Borrowers shall keep the Inventory and Equipment only at the
location set forth in Section 10 and such other locations of which Borrowers
give Bank prior written notice and as to which Bank has filed a financing
statement where needed to perfect Bank's security interest.

              7.11 Compliance. Become or be controlled by an "investment
company," within the meaning of the Investment Company Act of 1940, or become
principally engaged in, or undertake as one of its important activities, the
business of extending credit for the purpose of purchasing or carrying margin
stock, or use the proceeds of any Credit Extension for such purpose. Fail to
meet the minimum funding requirements of ERISA, permit a Reportable Event or
Prohibited Transaction, as defined in ERISA, to occur, fail to comply with the
Federal Fair Labor Standards Act or violate any law or regulation, which
violation could reasonably be

                                       16.

<PAGE>

expected to have a Material Adverse Effect, or a material adverse effect on the
Collateral or the priority of Bank's Lien on the Collateral, or permit any of
its Subsidiaries to do any of the foregoing.

              7.12 Negative Pledge Agreements. Permit the inclusion in any
contract to which it becomes a party of any provisions that could restrict or
invalidate the creation of a security interest in Borrowers' rights and
interests in any Collateral.

        8.    Events of Default.

              Any one or more of the following events shall constitute an Event
of Default by Borrowers under this Agreement:

              8.1 Payment Default. If any Borrower fails to pay any of the
Obligations as and when due and such failure continues for 3 calendar days or
more after the due date, provided that within such 3-day cure period, the
failure to pay shall not be deemed an Event of Default, but no Credit Extensions
will be made;

              8.2 Covenant Default. If any Borrower fails to perform any
obligation under Article 6 or violates any of the covenants contained in Article
7 of this Agreement, or fails or neglects to perform or observe any other
material term, provision, condition, covenant contained in this Agreement, in
any of the Loan Documents, or in any other present or future agreement between
any Borrower and Bank and as to any default under such other term, provision,
condition or covenant that can be cured, has failed to cure such default within
ten (10) days after any Borrower receives notice thereof or any officer of any
Borrower becomes aware thereof; provided, however, that if the default cannot by
its nature be cured within the ten (10) day period or cannot after diligent
attempts by Borrowers be cured within such ten day period, and such default is
likely to be cured within a reasonable time, then Borrowers shall have an
additional reasonable period (which shall not in any case exceed 30 days) to
attempt to cure such default, and within such reasonable time period the failure
to have cured such default shall not be deemed an Event of Default but no Credit
Extensions will be made;

              8.3 Material Adverse Change. If there occurs a material adverse
change in Borrowers' business or financial condition, or if there is a material
impairment of the prospect of repayment of any portion of the Obligations or a
material impairment of the value or priority of Bank's security interests in the
Collateral;

              8.4 Attachment. If any material portion of Borrowers' assets is
attached, seized, subjected to a writ or distress warrant, or is levied upon, or
comes into the possession of any trustee, receiver or person acting in a similar
capacity and such attachment, seizure, writ or distress warrant or levy has not
been removed, discharged or rescinded within ten (10) days, or if any Borrower
is enjoined, restrained, or in any way prevented by court order from continuing
to conduct all or any material part of its business affairs, or if a judgment or
other claim becomes a lien or encumbrance upon any material portion of
Borrowers' assets, or if a notice of lien, levy, or assessment is filed of
record with respect to any of Borrowers' assets by the United States Government,
or any department, agency, or instrumentality thereof, or by any state, county,
municipal, or governmental agency, and the same is not paid within ten days
after any Borrower

                                       17.

<PAGE>

receives notice thereof, provided that none of the foregoing shall constitute an
Event of Default where such action or event is stayed or an adequate bond has
been posted pending a good faith contest by Borrowers (provided that no Credit
Extensions will be required to be made during such cure period);

         8.5    Insolvency. If any Borrower becomes insolvent, or if an
Insolvency Proceeding is commenced by any Borrower, or if an Insolvency
Proceeding is commenced against any Borrower and is not dismissed or stayed
within 30 days (provided that no Credit Extensions will be made prior to the
dismissal of such Insolvency Proceeding);

         8.6    Other Agreements. If there is a default in any agreement to

continuance of an Event of Default, Bank may, at its election, without notice of

which are authorized by Borrowers:

                (a)   Declare all Obligations, whether evidenced by this
Agreement, by any of the other Loan Documents, or otherwise, immediately due and
payable (provided that upon the occurrence of an Event of Default described in
Section 8.5, all Obligations shall become immediately due and payable without
any action by Bank);

                (b)   Cease advancing money or extending credit to or for the
benefit of Borrowers under this Agreement or under any other agreement between
any Borrower and Bank;

                (c)   Settle or adjust disputes and claims directly with account
debtors for amounts, upon terms and in whatever order that Bank reasonably
considers advisable;

                                       18.

<PAGE>

                (d)   Make such payments and do such acts as Bank considers
necessary or reasonable to protect its security interest in the Collateral. Each
Borrower agrees to assemble the Collateral if Bank so requires, and to make the
Collateral available to Bank as Bank may designate. Each Borrower authorizes
Bank to enter the premises where the Collateral is located, to take and maintain
possession of the Collateral, or any part of it, and to pay, purchase, contest,
or compromise any encumbrance, charge, or lien which in Bank's determination
appears to be prior or superior to its security interest and to pay all
reasonable expenses incurred in connection therewith. With respect to any of
Borrowers' owned premises, each Borrower hereby grants Bank a license to enter
into possession of such premises and to occupy the same, without charge, in
order to exercise any of Bank's rights or remedies provided herein, at law, in
equity, or otherwise;

                (e)   Set off and apply to the Obligations any and all (i)
balances and deposits of any Borrower held by Bank, or (ii) indebtedness at any
time owing to or for the credit or the account of any Borrower held by Bank;

                (f)   Ship, reclaim, recover, store, finish, maintain, repair,
prepare for sale, advertise for sale, and sell (in the manner provided for
herein) the Collateral. Bank is hereby granted a license or other right, solely
pursuant to the provisions of this Section 9.1, to use, without charge,
Borrowers' labels, patents, copyrights, rights of use of any name, trade
secrets, trade names, trademarks, service marks, and advertising matter, or any
property of a similar nature, as it pertains to the Collateral, in completing
production of, advertising for sale, and selling any Collateral and, in
connection with Bank's exercise of its rights under this Section 9.1, Borrowers'
rights under all licenses and all franchise agreements shall inure to Bank's
benefit;

                (g)   Sell the Collateral at either a public or private sale, or
both, by way of one or more contracts or transactions, for cash or on terms, in
such manner and at such places (including Borrowers' premises) as Bank
determines is commercially reasonable, and apply any proceeds to the Obligations
in whatever manner or order Bank deems appropriate;

                (h)   Bank may credit bid and purchase at any public sale; and

                (i)   Any deficiency that exists after disposition of the
Collateral as provided above will be paid immediately by Borrowers.

         9.2    Power of Attorney. Effective only upon the occurrence and during
the continuance of an Event of Default, Borrowers hereby irrevocably appoint
Bank (and any of Bank's designated officers, or employees) as Borrowers' true
and lawful attorney to: (a) send requests for verification of Accounts or notify
account debtors of Bank's security interest in the Accounts; (b) endorse
Borrowers' names on any checks or other forms of payment or security that may
come into Bank's possession; (c) sign Borrowers' names on any invoice or bill of
lading relating to any Account, drafts against account debtors, schedules and
assignments of Accounts, verifications of Accounts, and notices to account
debtors; (d) dispose of any Collateral; (e) make, settle, and adjust all claims
under and decisions with respect to Borrowers' policies of insurance; (f) settle
and adjust disputes and claims respecting the accounts directly with account
debtors, for amounts and upon terms which Bank determines to be reasonable; (g)

                                       19.

<PAGE>

to modify, in its sole discretion, any intellectual property security agreement
entered into between Borrowers and Bank without first obtaining Borrowers'
approval of or signature to such modification by amending Exhibits A, B, and C,
thereof, as appropriate, to include reference to any right, title or interest in
any Copyrights, Patents or Trademarks acquired by any Borrower after the
execution hereof or to delete any reference to any right, title or interest in
any Copyrights, Patents or Trademarks in which a Borrower no longer has or
claims to have any right, title or interest; (h) to file, in its sole
discretion, one or more financing or continuation statements and amendments
thereto, relative to any of the Collateral; and (i) to transfer the Intellectual
Property Collateral into the name of Bank or a third party to the extent
permitted under the California Uniform Commercial Code; provided Bank may
exercise such power of attorney to sign the name of Borrowers on any of the
documents described in Section 4.2 regardless of whether an Event of Default has
occurred. The appointment of Bank as Borrowers' attorney in fact, and each and
every one of Bank's rights and powers, being coupled with an interest, is
irrevocable until all of the Obligations have been fully repaid and performed
and Bank's obligation to provide advances hereunder is terminated.

         9.3    Accounts Collection.  Upon the occurrence of and during the
continuance of any Event of Default, Bank may notify any Person owing funds to
Borrowers of Bank's security interest in such funds and verify the amount of
such Account. Borrowers shall collect all amounts owing to Borrowers for Bank,
receive in trust all payments as Bank's trustee, and immediately deliver such
payments to Bank in their original form as received from the account debtor,
with proper endorsements for deposit.

         9.4    Bank Expenses.  If any Borrower fails to pay any amounts or
furnish any required proof of payment due to third persons or entities, as
required under the terms of this Agreement, then Bank may do any or all of the
following after reasonable notice to such Borrower: (a) make payment of the same
or any part thereof; (b) set up such reserves under the Revolving Facility as
Bank deems necessary to protect Bank from the exposure created by such failure;
or (c) obtain and maintain insurance policies of the type discussed in Section
6.5 of this Agreement, and take any action with respect to such policies as Bank
deems prudent. Any amounts so paid or deposited by Bank shall constitute Bank
Expenses, shall be immediately due and payable, and shall bear interest at the
then applicable rate hereinabove provided, and shall be secured by the
Collateral. Any payments made by Bank shall not constitute an agreement by Bank
to make similar payments in the future or a waiver by Bank of any Event of
Default under this Agreement.

         9.5    Bank's Liability for Collateral.  So long as Bank complies with
reasonable banking practices and Section 9-207 of the Code, Bank shall not in
any way or manner be liable or responsible for: (a) the safekeeping of the
Collateral; (b) any loss or damage thereto occurring or arising in any manner or
fashion from any cause; (c) any diminution in the value thereof; or (d) any act
or default of any carrier, warehouseman, bailee, forwarding agency, or other
person whomsoever. All risk of loss, damage or destruction of the Collateral
shall be borne by Borrowers.

         9.6    Remedies Cumulative.   Bank's rights and remedies under this
Agreement, the Loan Documents, and all other agreements shall be cumulative.
Bank shall have all other rights and remedies not inconsistent herewith as
provided under the Code, by law, or in

                                       20.

<PAGE>

equity. No exercise by Bank of one right or remedy shall be deemed an election,
and no waiver by Bank of any Event of Default on Borrowers' part shall be deemed
a continuing waiver. No delay by Bank shall constitute a waiver, election, or
acquiescence by it. No waiver by Bank shall be effective unless made in a
written document signed on behalf of Bank and then shall be effective only in
the specific instance and for the specific purpose for which it was given.

                9.7    Demand; Protest.  Each Borrower waives demand, protest,
notice of protest, notice of default or dishonor, notice of payment and
nonpayment, notice of any default, nonpayment at maturity, release, compromise,
settlement, extension, or renewal of accounts, documents, Instruments, Chattel
Paper, and guarantees at any time held by Bank on which such Borrower may in any
way be liable.

         10.    Notices.

periods with respect to actions that may be brought against Bank have run.

           12.8   Confidentiality. In handling any confidential information Bank
and all employees and agents of Bank shall exercise the same degree of care that

that such third party is prohibited from disclosing such information.

    13.    Suretyship Waivers.

<PAGE>

terms of the Loan Documents or from a material breach thereof by Bank which
under applicable law has the effect of discharging any Borrower from the
Obligations as to which this Agreement is sought to be enforced; (d) the benefit
of any act or omission by Bank which directly or indirectly results in or aids
the discharge of any Borrower from any of the Obligations by operation of law or
otherwise; (e) except as expressly provided herein, all notices whatsoever,
including notice of acceptance of the incurring of the Obligations; (f) any
right it may have to require Bank to disclose to it any information that Bank
may now or hereafter acquire concerning the financial condition or any

(g) any requirement that Bank exhaust any right, power or remedy or proceed
against any other Borrower or any other security for, or any guarantor of, or
any other party liable for, any of the Obligations, or any portion thereof. Each
Borrower specifically agrees that it shall not be necessary or required, and
Borrowers shall not be entitled to require, that Bank (i) file suit or proceed
to assert or obtain a claim for personal judgment against any other Borrower for
all or any part of the Obligations; (ii) make any effort at collection or
enforcement of all or any part of the Obligations from any Borrower; (iii)
foreclose against or seek to realize upon the Collateral or any other security
now or hereafter existing for all or any part of the Obligations; (iv) file suit
or proceed to obtain or assert a claim for personal judgment against any
Borrower or any guarantor or other party liable for all or any part of the
Obligations; (v) exercise or assert any other right or remedy to which Bank is
or may be entitled in connection with the Obligations or any security or
guaranty relating thereto to assert; or (vi) file any claim against assets of
one Borrower before or as a condition of enforcing the liability of any other
Borrower under this Agreement. Without limiting the generality of the foregoing,
each Borrower expressly waives the benefit of California Civil Code Sections
2809, 2810, 2819, 2839, 2845, 2848, 2849, 2850, 2899 and 1432. WITHOUT LIMITING
THE FOREGOING IN ANY WAY, EACH BORROWER HEREBY IRREVOCABLY WAIVES AND RELEASES:

               (a)  Any and all rights it may have at any time (whether arising
directly or indirectly, by operation of law, contract or otherwise) to require
the marshaling of any assets of any Borrower, which right of marshaling might
otherwise arise from any such payments made or obligations performed;

               (b)  Any and all rights that would result in such Borrower being
deemed a "creditor" under the United States Code of any other Borrower or any
other Person, on account of payments made or obligations performed by such
Borrower; and

               (c)  Until such time as the Obligations have been satisfied in
full, any claim, right or remedy which it may now have or hereafter acquire
against any other Borrower that arises hereunder and/or from the performance by
it hereunder including any claim, remedy or right of subrogation, reimbursement,
exoneration, contribution, indemnification, or participation in any claim, right
or remedy of Bank against any other Borrower or any collateral security which
Bank now has or may hereafter acquire, whether or not such claim, right or
remedy arises in equity, under contract, by statute, under common law or
otherwise.

                                       24.

THIS WARRANT AND THE SHARES ISSUABLE HEREUNDER HAVE NOT BEEN REGISTERED UNDER
THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, PLEDGED OR
OTHERWISE TRANSFERRED WITHOUT AN EFFECTIVE REGISTRATION THEREOF UNDER SUCH ACT
OR PURSUANT TO RULE 144 OR AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE
CORPORATION AND ITS COUNSEL THAT SUCH REGISTRATION IS NOT REQUIRED.

                            WARRANT TO PURCHASE STOCK

Corporation:              InPhonic, Inc., a Delaware Corporation
Number of Shares:         75,758
Class of Stock:           Common Stock
Initial Exercise Price:   The Conversion Price of Series D-1 Preferred Stock, as
                          defined in, and as adjusted from time to time in
                          accordance with, the Seventh Amended and Restated
                          Certificate of Incorporation of InPhonic, Inc. (which
                          price, as of the date hereof, is $1.32 per share)
Issue Date:               March 1, 2002
Expiration Date:          March 1, 2009 (Subject to Section 4.1)

     THIS WARRANT CERTIFIES THAT, for good and valuable consideration, the
receipt of which is hereby acknowledged, COMERICA BANK - CALIFORNIA, successor
by merger to Imperial Bank, or its assignee ("Holder") is entitled to purchase
the number of fully paid and nonassessable shares of the class of securities
(the "Shares") of the corporation (the "Company") at the initial exercise price
per Share (the "Warrant Price") all as set forth above and as adjusted pursuant
to Article 2 of this warrant, subject to the provisions and upon the terms and
conditions set forth in this warrant.

ARTICLE 1. EXERCISE.

     1.1 Method of Exercise. Holder may exercise this warrant by delivering this
warrant and a duly executed Notice of Exercise in substantially the form
attached as Appendix 1 to the principal office of the Company. Unless Holder is
exercising the conversion right set forth in Section 1.2, Holder shall also
deliver to the Company a check for the aggregate Warrant Price for the Shares
being purchased.

     1.2 Conversion Right. In lieu of exercising this warrant as specified in
Section 1.1, Holder may from time to time convert this warrant, in whole or in
part, into a number of Shares determined by dividing (a) the aggregate fair
market value of the Shares or other securities otherwise issuable upon exercise
of this warrant minus the aggregate Warrant Price of such Shares by (b) the fair
market value of one Share. The fair market value of the Shares shall be
determined pursuant to Section 1.4.

     1.3 Intentionally Omitted

     1.4 Fair Market Value. If the Shares are traded regularly in a public
market, the fair market value of the Shares shall be the closing price of the
Shares (or the closing price of the Company's stock into which the Shares are
convertible) reported for the business day immediately before Holder delivers
its Notice of Exercise to the Company. If the Shares are not regularly traded in
a public market, the Board of Directors of the Company shall determine fair
market value in its reasonable good faith judgment.

                                       1.

<PAGE>

     1.5  Delivery of Certificate and New Warrant. Promptly after Holder
exercises or converts this warrant, the Company shall deliver to Holder
certificates for the Shares acquired and, if this warrant has not been fully
exercised or converted and has not expired, a new warrant representing the
Shares not so acquired.

     1.6  Replacement of Warrants. On receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
this warrant and, in the case of loss, theft or destruction, on delivery of an
indemnity agreement reasonably satisfactory in form and amount to the Company
or, in the case of mutilation, on surrender and cancellation of this warrant,
the Company at its expense shall execute and deliver, in lieu of this warrant, a
new warrant of like tenor.

     1.7  Repurchase on Sale, Merger, or Consolidation of the Company.

          1.7.1 "Acquisition." For the purpose of this warrant, "Acquisition"
means any sale, license (other than in the ordinary course of business), or
other disposition of all or substantially all of the assets (including
intellectual property) of the Company, or any reorganization, consolidation, or
merger of the Company where the holders of the Company's securities before the
transaction beneficially own less than 50% of the outstanding voting securities
of the surviving entity after the transaction.

          1.7.2 Assumption of Warrant. If upon the closing of any Acquisition
the successor entity assumes the obligations of this warrant, then this warrant
shall be exercisable for the same securities, cash, and property as would be
payable for the Shares issuable upon exercise of the unexercised portion of this
warrant as if such Shares were outstanding on the record date for the
Acquisition and subsequent closing. The Warrant Price shall be adjusted
accordingly. The Company shall use reasonable efforts to cause the surviving
corporation to assume the obligations of this warrant.

          1.7.3 Nonassumption. If upon the closing of any Acquisition the
successor entity does not assume the obligations of this warrant and Holder has
not otherwise exercised this warrant in full, then Holder shall have the option
either to (a) deem this warrant to have been automatically converted pursuant to
Section 1.2 and thereafter Holder shall participate in the Acquisition on the
same terms as other holders of the same class of securities of the Company; or
(b) require the Company to purchase this warrant for cash upon the closing of
the Acquisition for an amount per Share equal to three (3) times the Warrant
Price.

ARTICLE 2. ADJUSTMENTS TO THE SHARES.

     2.1  Stock Dividends, Splits, Etc. If the Company declares or pays a
dividend on its common stock payable in common stock, or other securities,
subdivides the outstanding common stock into a greater amount of common stock,
then upon exercise of this warrant, for each Share acquired, Holder shall
receive, without cost to Holder, the total number and kind of securities to
which Holder would have been entitled had Holder owned the Shares of record as
of the date the dividend or subdivision occurred.

     2.2  Reclassification, Exchange or Substitution. Upon any reclassification,
exchange, substitution, or other event that results in a change of the number
and/or class of the securities issuable upon exercise or conversion of this
warrant, Holder shall be entitled to receive, upon exercise or conversion of
this warrant, the number and kind of securities and property that Holder would
have received for the Shares if this warrant had been exercised immediately
before such reclassification, exchange, substitution, or other event. Such an
event shall include any automatic conversion of the outstanding or issuable
securities of the Company of the same class or series as the Shares to common
stock pursuant to the terms of the Company's Certificate of Incorporation upon
the closing of a registered public offering of the Company's common stock. The
Company or its successor shall promptly issue to

                                       2.

<PAGE>

Holder a new warrant for such new securities or other property. The new warrant
shall provide for adjustments which shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Article 2 including, without
limitation, adjustments to the Warrant Price and to the number of securities or
property issuable upon exercise of the new warrant. The provisions of this
Section 2.2 shall similarly apply to successive reclassifications, exchanges,
substitutions, or other events.

     2.3  Adjustments for Combinations, Etc. If the outstanding Shares are
combined or consolidated, by reclassification or otherwise, into a lesser number
of shares, the Warrant Price shall be proportionately increased. If the
outstanding Shares are combined or consolidated, by reclassification or
otherwise, into a greater number of shares, the Warrant Price shall be
proportionately decreased.

     2.4  Adjustments for Diluting Issuances. The Warrant Price and the number
of Shares issuable upon exercise of this warrant shall be subject to adjustment,
from time to time, in the manner set forth on Exhibit A.

     2.5  No Impairment. The Company shall not, by amendment of its Certificate
of Incorporation or through a reorganization, transfer of assets, consolidation,
merger, dissolution, issue, or sale of securities or any other voluntary action,
avoid or seek to avoid the observance or performance of any of the terms to be
observed or performed under this warrant by the Company, but shall at all times
in good faith assist in carrying out all the provisions of this Article 2 and in
taking all such action as may be necessary or appropriate to protect Holder's
rights under this Article against impairment.

     2.6  Certificate as to Adjustments. Upon each adjustment of the Warrant
Price, the Company at its expense shall promptly compute such adjustment, and
furnish Holder with a certificate of its Chief Financial Officer setting forth
such adjustment and the facts upon which such adjustment is based. The Company
shall, upon written request, furnish Holder a certificate setting forth the
Warrant Price in effect upon the date thereof and the series of adjustments
leading to such Warrant Price.

ARTICLE 3. REPRESENTATIONS AND COVENANTS OF THE COMPANY.

     3.1  Representations and Warranties. The Company hereby represents and
warrants to the Holder as follows:

          (a) The initial Warrant Price referenced on the first page of this
warrant is not greater than the fair market value of the Shares as of the date
of this warrant.

          (b) All Shares which may be issued upon the exercise of the purchase
right represented by this warrant, and all securities, if any, issuable upon
conversion of the Shares, shall, upon issuance, be duly authorized, validly
issued, fully paid and nonassessable, and free of any liens and encumbrances
except for restrictions on transfer provided for herein or under applicable
federal and state securities laws.

          (c) The Company's capitalization table previously provided to Holder
is true and complete as of the Issue Date.

     3.2  Notice of Certain Events. If the Company proposes at any time (a) to
declare any dividend or distribution upon its common stock, whether in cash,
property, stock, or other securities and whether or not a regular cash dividend;
(b) to offer for subscription pro rata to the holders of any class or series of
its stock any additional shares of stock of any class or series or other rights;
(c) to effect any reclassification or recapitalization of common stock; or (d)
to merge or consolidate with or into any other corporation, or sell, lease,
license (other than in the ordinary course of business), or convey all or
substantially all of its assets, or to liquidate, dissolve or wind up, then, in
connection with each such event, the Company shall give Holder (1) at least 20
days prior written notice of the

                                       3.

<PAGE>

date on which a record will be taken for such dividend or distribution (and
specifying the date on which the holders of common stock will be entitled
thereto) or for determining rights to vote, if any, in respect of the matters
referred to in (a) above; and (2) in the case of the matters referred to in (b)
and (c) above at least 20 days prior written notice of the date when the same
will take place (and specifying the date on which the holders of common stock
will be entitled to exchange their common stock for securities or other property
deliverable upon the occurrence of such event).

     3.3  Information Rights. So long as the Holder holds this warrant and/or
any of the Shares, the Company shall deliver to the Holder (a) promptly after
mailing, copies of all communiques to the shareholders of the Company, (b)
within one hundred twenty (120) days after the end of each fiscal year of the
Company, the annual audited financial statements of the Company certified by
independent public accountants of recognized standing and (c) within forty-five
(45) days after the end of each of the first three quarters of each fiscal year,
the Company's quarterly, unaudited financial statements.

     3.4  REGISTRATION UNDER SECURITIES ACT OF 1933, AS AMENDED. THE COMPANY
AGREES THAT THE SHARES OR, IF THE SHARES ARE CONVERTIBLE INTO COMMON STOCK OF
THE COMPANY, SUCH COMMON STOCK, SHALL BE SUBJECT TO THE REGISTRATION RIGHTS SET
FORTH ON EXHIBIT B, IF ATTACHED.

ARTICLE 4. MISCELLANEOUS.

     4.1  Term: Notice of Expiration. This warrant is exercisable in whole or in
part, at any time and from time to time on or before the Expiration Date set
forth above; provided, however, that if the Company completes its initial public
offering within the three-year period immediately prior to the Expiration Date,
the Expiration Date shall automatically be extended until the third anniversary
of the effective date of the Company's initial public offering. If this warrant
has not been exercised prior to the Expiration Date, this warrant shall be
deemed to have been automatically exercised on the Expiration Date by "cashless"
conversion pursuant to Section 1.2.

     4.2  Legends. This warrant and the Shares (and the securities issuable,
directly or indirectly, upon conversion of the Shares, if any) shall be
imprinted with a legend in substantially the following form:

THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
AMENDED, AND MAY NOT BE SOLD, PLEDGED OR OTHERWISE TRANSFERRED WITHOUT AN
EFFECTIVE REGISTRATION THEREOF UNDER SUCH ACT OR PURSUANT TO RULE 144 OR AN
OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE CORPORATION AND ITS COUNSEL
THAT SUCH REGISTRATION IS NOT REQUIRED.

     4.3  Compliance with Securities Laws on Transfer. This warrant and the
Shares issuable upon exercise of this warrant (and the securities issuable,
directly or indirectly, upon conversion of the Shares, if any) may not be
transferred or assigned in whole or in part without compliance with applicable
federal and state securities laws by the transferor and the transferee
(including, without limitation, the delivery of investment representation
letters and legal opinions reasonably satisfactory to the Company). The Company
shall not require Holder to provide an opinion of counsel if the transfer is to
an affiliate of Holder or if there is no material question as to the
availability of current information as referenced in Rule 144(c), Holder
represents that it has complied with Rule 144(d) and (e) in reasonable detail,
