                   FIRST MODIFICATION OF AMENDED AND RESTATED
               REVOLVING LINE OF CREDIT LOAN AGREEMENT, TERM LOANS
                        AGREEMENT AND SECURITY AGREEMENT

     THIS FIRST MODIFICATION OF AMENDED AND RESTATED REVOLVING LINE OF CREDIT
LOAN AGREEMENT, TERM LOANS AGREEMENT AND SECURITY AGREEMENT ("First
Modification") is entered into effective as of the___day of July, 2001, by and
between On-Site Sourcing, Inc. ("Borrower"), a Delaware corporation, with its
principal office at 1111 North Nineteenth Street, 6th Floor, Arlington, Virginia
22209, and First Union National Bank (the "Lender"), a national banking
association with an address of 1970 Chain Bridge Road, McLean, Virginia 22102.

                                    RECITALS:

     R-1. Lender made a loan in the form of a revolving line of credit ("Line of
Credit") to Borrower, currently in the maximum principal sum of Seven Million
and 00/100 Dollars ($7,000,000.00), evidenced by an Amended and Restated
Revolving Note, dated as of May 30, 2001 (the "Revolving Note"). The Line of
Credit is governed and secured by that certain Amended and Restated Revolving
Line of Credit Loan Agreement, Term Loans Agreement and Security Agreement
executed by Borrower and Lender dated as of May 30, 2001 (as so modified, the
"Loan Agreement").

     R-2. The Loan Agreement also governs and secures (1) that certain term loan
to Borrower and North Henry Street Realty Company, LLC, a Delaware limited
liability company ("North Henry"), in the original principal amount of Five
Million Eight Hundred Thousand and 00/100 Dollars ($5,800,000.00), as evidenced
by that certain Commercial Note executed by Borrower and North Henry dated as of
November 15, 2000; and (2) that certain term loan to Borrower in the original
principal amount of One Million One Hundred Twenty Five Thousand and 00/100
Dollars ($1,125,000.00), as evidenced by that certain Term Note dated June 12,
2000;

     R-3. Lender has simultaneously herewith advanced to Borrower the sum of One
Million, Seven Hundred Eighty Thousand, Three Hundred and 00/100 Dollars
($1,780,300.00) (the "$1,780,300.00 Term Loan"), and Borrower has executed and
delivered to Lender a Term Note, of even date (the "$1,780,300.00 Term Note"),
in the original principal amount of One Million, Seven Hundred Eighty Thousand,
Three Hundred and 00/100 Dollars ($1,780,300.00). The $1,780,300.00 Term Note
provides, among other things, that an event of default under the Loan Agreement
shall allow the Lender, at its option, to accelerate the maturity of, and demand
immediate payment of, the amounts owing under the $1,780,300.00 Term Note. The
$1,780,300.00 Term Loan is to be secured by the Collateral, as defined in the
Loan Agreement. The purpose of the $1,780,300.00 Term Loan is to finance
computer and other equipment used in the Borrower's business.

     R-4. Borrower and Lender have agreed to modify the Loan Agreement to, in
part, govern and secure the $1,780,300.00 Loan, and for certain other purposes.

     warrants and represents to the Lender that:

     a.   The Borrower's books and records properly reflect the Borrower's

          financial condition has occurred since the last date that the Borrower
          provided financial reports to the Lender; and

     b.   No litigation is pending or threatened against the Borrower of which

          authorized and approved in accordance with the Borrower's
          organizational documents; and

     e.   This First Modification, together with all documents executed in

          enforceable obligations, and the execution and delivery of this First

     $1,780,300.00 Term Loan, with interest, at the time and in the manner

jurisdiction revoking, limiting or curtailing, or seeking to revoke, limit or curtail, such power and authority or qualification. 

        3.2    Due Authorization.    The Company has all requisite power and authority to execute, deliver and perform its
obligations under the Agreements, and the Agreements have been duly authorized and validly executed and delivered by the Company and constitute legal, valid and binding agreements of the Company
enforceable against the Company in accordance with their terms, except as rights to indemnity and contribution may be limited by state or federal securities laws or the public policy underlying such
laws, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors' and contracting parties' rights generally and except
as enforceability may be subject to general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law). 

        3.3    Non-Contravention.    The execution and delivery of the Agreements, the issuance and sale of the
Shares to be sold by the Company under the Agreements, the fulfillment of the terms of the Agreements and the consummation of the transactions contemplated thereby will not (A) result in
conflict with or constitute a violation of, or default (with the passage of time or otherwise) under, (i) any bond, debenture, note or other evidence of indebtedness, or any lease, contract,
indenture, mortgage, deed of trust, loan agreement, joint venture or other agreement or instrument to which the Company or any of its Subsidiaries is a party or by which the Company or 

2

 

any of its Subsidiaries or their respective properties are bound, where such conflict, violation or default is reasonably expected to result in a Material Adverse Effect, (ii) the certificate
of incorporation, by-laws or other organizational documents of the Company or any of its Subsidiaries, or (iii) any law, administrative regulation, ordinance or order of any court
or governmental agency, arbitration panel or authority binding upon the Company or any of its Subsidiaries or their respective properties, where such conflict, violation or default is likely to result
in a Material Adverse Effect or (B) result in the creation or imposition of any lien, encumbrance, claim, security interest or restriction whatsoever upon any of the material properties or
assets of the Company or any of its Subsidiaries or an acceleration of indebtedness pursuant to any obligation, agreement or condition contained in any material bond,
debenture, note or any other evidence of indebtedness or any material indenture, mortgage, deed of trust or any other agreement or instrument to which the Company or any of its Subsidiaries is a party
or by which any of them is bound or to which any of the property or assets of the Company or any of its Subsidiaries is subject. No consent, approval, authorization or other order of, or registration,
qualification or filing with, any regulatory body, administrative agency, or other governmental body in the United States is required for the execution and delivery of the Agreements by the Company
and the valid issuance or sale of the Shares by the Company pursuant to the Agreements, other than such as have been made or obtained, and except for any filings required to be made under federal or
state securities laws. 

        3.4    Capitalization.    The outstanding capital stock of the Company as of September 30, 2001 is as described
in the Company's Quarterly Report on Form 10-Q for the quarter ended September 30, 2001. The Company has not issued any capital stock since September 30, 2001 other
than pursuant to (i) the exercise of employee stock options under the stock option plans disclosed in the SEC Reports, (ii) the exercise of rights under the Company's Employee Stock
Purchase Plan disclosed in the SEC Reports and (iii) the exercise of warrants by U.S. Bancorp Piper Jaffray. The Shares to be sold pursuant to the Agreements have been duly authorized, and when
issued and paid for in accordance with the terms of the Agreements, will be duly and validly issued, fully paid and nonassessable. The outstanding shares of capital stock of the Company have been duly
and validly issued and are fully paid and nonassessable, have been issued in compliance with the registration requirements of federal and state securities laws, and were not issued in violation of any
preemptive rights or similar rights to subscribe for or purchase securities. Except for options issued under the Company's stock option plans, warrants outstanding as described in the SEC Reports and
rights under the Company's Employee Stock Purchase Plan or Rights Agreement with Wells Fargo Bank Minnesota (formerly Norwest Bank Minnesota) as Rights Agent, there are no outstanding rights
(including, without limitation, preemptive rights), warrants or options to acquire, or instruments convertible into or exchangeable for, any unissued shares of capital stock or other equity interest
in the Company, or any contract, commitment, agreement, understanding or arrangement of any kind, in either case to which the Company is a party and providing for the issuance or sale of any capital
stock of the Company, any such convertible or exchangeable securities or any such rights, warrants or options. Without limiting the foregoing, no preemptive right, co-sale right,
registration right, right of first refusal or other similar right exists with respect to the issuance and sale of the Shares, except as provided in the Agreements. There are no stockholders
agreements, voting agreements or other similar agreements with respect to the Common Stock to which the Company is a party. The Company owns the entire equity interest in the Subsidiaries, free and
clear of any pledge, lien, security interest, encumbrance, claim or equitable interest. 

        3.5    Legal Proceedings.    There is no material legal or governmental proceeding pending, or to the knowledge of the
Company, threatened, to which the Company or any of its Subsidiaries is a party or of which the business or property of the Company or any of its Subsidiaries is subject that is required to be
disclosed and that is not so disclosed in the SEC Reports. Neither the 

3

 

Company nor any of its Subsidiaries is a party to the provisions of any injunction, judgment, decree or order of any court, regulatory body, administrative agency or other government body which is
material to the business or operation of the Company and its Subsidiaries, taken as a whole. 

        3.6    No Violations.    Neither the Company nor any of its Subsidiaries is in violation of its certificate of
incorporation, bylaws or other organizational documents, or in violation of any law, administrative regulation, ordinance or order of any court or governmental agency, arbitration panel or authority
applicable to the Company or any of its Subsidiaries, which violation, individually or in the aggregate, is reasonably likely to have a Material Adverse Effect, nor is the Company or any of its
Subsidiaries in default (and there exists no condition which, with the passage of time or otherwise, would constitute a default) in the performance of any bond, debenture, note or any other evidence
of indebtedness or any indenture, mortgage, deed of trust or any other material agreement or instrument to which the Company or any of its Subsidiaries is a party or by which the Company or any of its
Subsidiaries is bound or by which the property of the Company or any of its Subsidiaries is bound, which default is reasonably likely to have a Material Adverse Effect.

3.1, 3.11, 3.12 and 3.21, each of the Company and its Subsidiaries has all necessary franchises, licenses, certificates and other authorizations from any foreign, federal, state or local government or
governmental agency, department or body that are currently necessary for the operation of the business of the Company and its Subsidiaries as currently conducted, except where the failure to currently
possess such franchises, licenses, certificates and other authorizations is not reasonably be expected to have a Material Adverse Effect. 

        3.8    Intellectual Property.    

        (a)  Except for matters which are not reasonably likely to have a Material Adverse Effect, (i) each of the Company and
its Subsidiaries has ownership of, or a license or other legal right to use, all patents, copyrights, trade secrets, trademarks, customer lists, designs, manufacturing or other processes, computer

        (e)  No proceedings are pending, or to the knowledge of the Company, threatened, which challenge the rights of the Company or
any of its Subsidiaries in respect of the Company's or any of its Subsidiaries' right to the use of the Intellectual Property, except for matters which are not reasonably likely to have a Material
Adverse Effect. 

        3.9    Financial Statements.    The consolidated financial statements of the Company and the related notes contained

Securities Exchange Act of 1934, as amended (the "Exchange Act"), and is listed on the Nasdaq National Market (the "Nasdaq Stock

        4.    Representations, Warranties and Covenants of the Investor.    

        4.1    Investor Knowledge and Status.    The Investor represents and warrants to, and covenants with, the Company
that: (i) the Investor is an "accredited investor" as defined in Regulation D under the Securities Act, is knowledgeable, sophisticated and experienced in making, and is qualified to
make decisions with respect to, investments in securities presenting an investment decision like that involved in the purchase of the Shares, and has requested, received, reviewed and considered all
information it deemed relevant in making an informed decision to purchase the Shares; (ii) the Investor understands that the Shares are "restricted securities" and have not been registered
under the Securities Act and is acquiring the number of Shares set forth in paragraph 3 of the Stock Purchase Agreement in the ordinary course of its business and for its own account for
investment only, has no present intention of distributing any of such Shares and has no arrangement or understanding with any other persons regarding the distribution of such Shares (this
representation and warranty not limiting the Investor's right to sell Shares pursuant to the Registration Statement or otherwise, or other than with respect to any claim arising out of a breach of
this representation and warranty, the Investor's right to indemnification under Section 6.3); (iii) the Investor will not, directly or indirectly, offer, sell, pledge, transfer or
otherwise dispose of (or solicit any offers to buy, purchase or otherwise acquire or take a pledge of) any of the Shares except in compliance with the Securities Act, applicable state securities laws
and the respective rules and regulations promulgated thereunder; (iv) the Investor has answered all questions in paragraph 3 of the Stock Purchase Agreement and the Investor
Questionnaire attached hereto as Exhibit B for use in preparation of the Registration Statement and the answers thereto are true and correct as of the date hereof and will be true and correct

among other things, the bona fide nature of the Investor's investment intent as expressed herein and the information provided in the Investor Questionnaire. The Placement Agent is not authorized to
make any representation or use any information in connection with the placement, purchase and sale of the Shares, and no person is authorized to provide any representation which is inconsistent or in
addition to those in the SEC Reports. The Investor acknowledges that it has not received or relied on any such representations. 

        4.2    International Actions.    The Investor acknowledges, represents and agrees that no action has been or will be
taken in any jurisdiction outside the United States by the Company or the Placement Agent that would permit an offering of the Shares, or possession or distribution of offering materials in connection
with the issue of the Shares, in any jurisdiction outside the United States. If the Investor is located outside the United States, it has or will take all actions necessary for the sale of the Shares

without complying with the provisions of this Agreement, including Section 6.2 hereof, and
without effectively causing the prospectus delivery requirement under the Securities Act to be satisfied (unless the Investor is selling such Shares in a transaction not subject to the prospectus
delivery requirement), and the Investor acknowledges that the certificates evidencing the Shares will be imprinted with a legend that prohibits their transfer except in accordance therewith. The
Investor acknowledges that as set forth in, and subject to the provisions of, Section 6.2, there may occasionally be times when the Company, based on the advice of its counsel, determines that
it must suspend the use of the Prospectus forming a part of the Registration Statement until such time as an amendment to the Registration Statement has been filed by the Company and declared
effective by the SEC or until the Company has amended or supplemented such Prospectus. 

        4.4    Power and Authority.    The Investor further represents and warrants to, and covenants with, the Company that
(i) the Investor has full right, power, authority and capacity to enter into this Agreement and to consummate the transactions contemplated hereby and has taken all necessary action to
authorize the execution, delivery and performance of this Agreement, and (ii) this Agreement constitutes a valid and binding obligation of the Investor enforceable against the Investor in
accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors' and contracting parties' rights
generally and except as enforceability may be subject to general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law) and except as the
indemnification agreements of the Investors herein may be legally unenforceable. 

        4.5    Short Positions.    The Investor will not use any of the Shares acquired pursuant to this Agreement to cover
any short position in the Common Stock if doing so would be in violation of applicable securities laws. 

        4.6    No Investment, Tax or Legal Advice.    The Investor understands that nothing in the SEC Reports, this
Agreement, or any other materials presented to the Investor in connection with the purchase and sale of the Shares constitutes legal, tax or investment advice. The Investor has consulted such legal,
tax and investment advisors as it, in its sole discretion, has deemed necessary or appropriate in connection with its purchase of Shares. 

        4.7    Confidential Information.    The Investor covenants that from the date hereof it will maintain in confidence
all material non-public information regarding the Company received by the Investor from the Company after the date hereof, including the receipt and content of any Suspension Notice (as
defined in Section 6.2(c)) until such information (a) becomes generally publicly available other than through a violation of this provision by the Investor or its agents or (b) is
required to be disclosed in legal proceedings (such as by deposition, interrogatory, request for documents, subpoena, civil investigation demand, filing with any governmental authority or similar
process); provided, however, that before making any disclosure in reliance on this Section 4.7, the Investor will give the Company at least 15 days prior written notice (or such shorter
period as required by law) specifying the circumstances giving rise thereto and will furnish only that portion of the non-public information which is legally required and will exercise its
best efforts to obtain reliable assurance that confidential treatment will be accorded any non-public information so furnished. 

        4.8    Acknowledgments Regarding Placement Agent.    The Investor acknowledges that the Placement Agent has acted
solely as placement agent for the Company in connection with the Offering of the Shares by the Company, that certain of the information and data provided to the Investor in connection with the
transactions contemplated hereby have not been subjected to independent verification by the Placement Agent, and that the Placement Agent makes no 

8

 

representation or warranty with respect to the accuracy or completeness of such information, data or other related disclosure material. The Investor further acknowledges that in making its decision
to enter into this Agreement and purchase the Shares it has relied on its own examination of the Company and the terms of, and consequences, of holding the Shares. The Investor further acknowledges
that the provisions of this Section 4.8 are also for the benefit of, and may also be enforced by, the Placement Agent. 

        5.    Survival of Representations, Warranties and Agreements.    Notwithstanding any investigation made by any party
to this Agreement or by the Placement Agent, all covenants, agreements, representations and warranties made by the Company and the Investor herein shall survive the execution of this Agreement, the
delivery to the Investor of the Shares being purchased and the payment therefor. 

        6.    Registration of the Shares; Compliance with the Securities Act.    

        6.1    Registration Procedures and Expenses.    The Company shall: 

        (a)  subject to receipt of necessary information from the Investors, prepare and file with the SEC, within ten
(10) business days after the Closing Date, a registration statement on Form S-3 (the "Registration Statement") to enable the
resale of the Shares by the Investors from time to time through the automated quotation system of the Nasdaq Stock Market or in privately-negotiated transactions, and provide the Investor at least two
(2) business days to review and provide comments to the Registration Statement before filing with the SEC; 

        (b)  use its best efforts, subject to receipt of necessary information from the Investors, to cause the Registration Statement
to become effective as soon as practicable, but in no event later than sixty (60) days after the Registration Statement is filed by the Company. If the Registration Statement has not been
declared effective by the SEC on or before the date that is 90 days after the Closing Date (the "Required Effective Date"), the Company shall, on the 91st day and each
30th day thereafter, make a payment to the Investor as partial compensation for such delay (the "Late Registration Payments") equal to 1% of the purchase price paid for the Shares
purchased by the Investor and not previously sold by the Investor (but in no event to exceed 8% in the aggregate) until the Registration Statement is declared effective by the SEC. The Late
Registration Payments will be prorated on a daily basis during each 30 day period and will be paid to the Investor by wire transfer or check within five business days after the earlier of
(i) the end of each 30 day period following the Required Effective Date or (ii) the effective date of the Registration Statement; 

        (c)  use its best efforts to prepare and file with the SEC such amendments and supplements to the Registration Statement and
the Prospectus used in connection therewith as may be necessary to keep the Registration Statement current and effective for a period not exceeding, with respect to each Investor's Shares purchased
hereunder, the earlier of (i) the second anniversary of the Closing Date, (ii) the date on which the Investor may sell all Shares then held by the Investor without restriction by the
volume limitations of Rule 144(e) of the Securities Act or (iii) such time as all Shares purchased by such Investor in this Offering have been sold pursuant to a registration statement,
and to notify each Investor promptly upon the Registration Statement and each post-effective amendment thereto, being declared effective by the SEC; 

        (d)  furnish to the Investor with respect to the Shares registered under the Registration Statement such number of copies of
the Registration Statement, Prospectuses (including supplemental prospectuses) and preliminary versions of the Prospectus filed with the Securities Exchange Commission
("Preliminary Prospectuses") in conformity with the requirements of the Securities Act and such other documents as the Investor may reasonably request,
in order to facilitate the public sale or other disposition of all or any of the Shares by the Investor, 

9

 

provided, however, that unless waived by the Company in writing, the obligation of the Company to deliver copies of Prospectuses or Preliminary Prospectuses to the Investor shall be subject to the
receipt by the Company of reasonable assurances from the Investor that the Investor will comply with the applicable provisions of the Securities Act and of such other securities or blue sky laws as
may be applicable in connection with any use of such Prospectuses or Preliminary Prospectuses; 

        (e)  file documents required of the Company for normal blue sky clearance in states specified in writing by the Investor;
provided, however, that the Company shall not be required to qualify to do business or consent to service of process in any jurisdiction in which it is not now so qualified or has not so consented; 

        (f)    bear all expenses (other than underwriting discounts and commissions, if any) in connection with the procedures in
paragraph (a) through (e) of this Section 6.1 and the registration of the Shares pursuant to the Registration Statement; and 

        (g)  advise the Investors, promptly after it shall receive notice or obtain knowledge of the issuance of any stop order by the
SEC delaying or suspending the effectiveness of the Registration Statement or of the initiation of any proceeding for that purpose; and it will promptly use its commercially reasonable efforts to
prevent the issuance of any stop order or to obtain its withdrawal at the earliest possible moment if such stop order should be issued. 

        With
a view to making available to the Investor the benefits of Rule 144 (or its successor rule) and any other rule or regulation of the SEC that may at any time permit the
Investor to sell Shares to the public without registration, the Company covenants and agrees to: (i) make and keep public information available, as those terms are understood and defined in
Rule 144, until the earlier of (A) such date as all
of the Investor's Shares may be resold pursuant to Rule 144(k) or any other rule of similar effect or (B) such date as all of the Investor's Shares shall have been resold;
(ii) file with the SEC in a timely manner all reports and other documents required of the Company under the Securities Act and under the Exchange Act; and (iii) furnish to the Investor
upon request, as long as the Investor owns any Shares, (A) a written statement by the Company that it has complied with the reporting requirements of the Securities Act and the Exchange Act,
(B) a copy of the Company's most recent Annual Report on Form 10-K or Quarterly Report on Form 10-Q, and (C) such other information as may be
reasonably requested in order to avail the Investor of any rule or regulation of the SEC that permits the selling of any such Shares without registration. 

        It
shall be a condition precedent to the obligations of the Company to take any action pursuant to this Section 6.1 that the Investor shall furnish to the Company such information
regarding itself, the Shares to be sold by Investor, and the intended method of disposition of such securities as shall be required to effect the registration of the Shares. 

        The
Company understands that the Investor disclaims being an underwriter, but the Investor being deemed an underwriter by the SEC shall not relieve the Company of any obligations it has
hereunder. 

        6.2    Transfer of Shares After Registration; Suspension.    

        (a)  The Investor agrees that it will not effect any disposition of the Shares or its right to purchase the Shares that would
constitute a sale within the meaning of the Securities Act other than transactions exempt from the registration requirements of the Securities Act, except as contemplated in the Registration Statement
referred to in Section 6.1 and as described below, and that it will promptly notify the Company of any changes in the information set forth in the Registration Statement regarding the Investor
or its plan of distribution. 

        (b)  Except in the event that paragraph (c) below applies, the Company shall: (i) if deemed necessary by the
Company, prepare and file from time to time with the SEC a 

10

 

post-effective amendment to the Registration Statement or a supplement to the related Prospectus or a supplement or amendment to any document incorporated therein by reference or file any
other required document so that such Registration Statement will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make
the statements therein not misleading, and so that, as thereafter delivered to purchasers of the Shares being sold thereunder, such Prospectus will not contain an untrue statement of a material fact
or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading;
(ii) provide the Investor copies of any documents filed pursuant to Section 6.2(b)(i); and (iii) upon request, inform each Investor who so requests that the Company has complied
with its obligations in Section 6.2(b)(i) (or that, if the Company has filed a post-effective amendment to the Registration Statement which has not yet been declared
effective, the Company will notify the Investor to that effect, will use its reasonable efforts to secure
the effectiveness of such post-effective amendment as promptly as possible and will promptly notify the Investor pursuant to Section 6.2(b)(i) hereof when the amendment has
become effective). 

        (c)  Subject to paragraph (d) below, in the event: (i) of any request by the SEC or any other federal or state
governmental authority during the period of effectiveness of the Registration Statement for amendments or supplements to the Registration Statement or related Prospectus or for additional information;
(ii) of the issuance by the SEC or any other federal or state governmental authority of any stop order suspending the effectiveness of the Registration Statement or the initiation of any
proceedings for that purpose; (iii) of the receipt by the Company of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Shares
for sale in any jurisdiction or the initiation of any proceeding for such purpose; or (iv) of any event or circumstance which necessitates the making of any changes in the Registration
Statement or Prospectus, or any document incorporated or deemed to be incorporated therein by reference, so that, in the case of the Registration Statement, it will not contain any untrue statement of
a material fact or any omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, and that in the case of the Prospectus, it will not
contain any untrue statement of a material fact or any omission to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading; then the Company shall promptly deliver a certificate in writing to the Investor (the "Suspension Notice")
to the effect of the foregoing and, upon receipt of such Suspension Notice, the Investor will refrain from selling any Shares pursuant to the Registration Statement (a
"Suspension") until the Investor's receipt of copies of a supplemented or amended Prospectus prepared and filed by the Company, or until it is advised
in writing by the Company that the current Prospectus may be used, and has received copies of any additional or supplemental filings that are incorporated or deemed incorporated by reference in any
such Prospectus. In the event of any Suspension, the Company will use its reasonable best efforts to cause the use of the Prospectus so suspended to be resumed as soon as reasonably practicable after
delivery of a Suspension Notice to the Investors. In addition to and without limiting any other remedies (including, without limitation, at law or at equity) available to the Investor, the Investor
shall be entitled to specific performance in the event that the Company fails to comply with the provisions of this Section 6.2(c). 

        (d)  Notwithstanding the foregoing paragraphs of this Section 6.2, the Company shall use its best efforts to ensure
that the Investor shall not be prohibited from selling Shares under the Registration Statement as a result of Suspensions on more than two occasions of not more than 30 days in any twelve month
period. If a Suspension is in effect for more than 60 days (consecutive or non-consecutive) in any twelve-month period, the Company shall, on the 61st day of the
Suspension and each 30th day thereafter, make payments to the Investor as partial 

11

 

compensation for such delay until the Suspension is lifted. The amount of the payments made to the Investor will be equal to 1% of the purchase price paid for the Shares purchased by the Investor and
not previously sold by the Investor for each 30 days that sales cannot be made under the effective Registration Statement (but in no event to exceed 8% in the aggregate) beyond the period
allowed by the previous sentence. The number of Shares not previously sold as specified in the previous sentence shall be determined as of the end of the respective 30 day period. These
payments will be prorated on a daily basis during the 30 day period and will be paid to the Investor by check within five business days following the end of each month as to which payment is
due hereunder, assuming that the Investor delivered to the Company at least two business days prior thereto information with respect to the number of Shares not previously sold by the Investor
(together with reasonable supporting documentation). 

        (e)  Provided that a Suspension is not then in effect the Investor may sell Shares under the Registration Statement, provided
that it arranges for delivery of a current Prospectus to the transferee of such Shares. Upon receipt of a request therefor, the Company will provide an adequate number of current Prospectuses to the
Investor and to any other parties requiring such Prospectuses. 

        (f)    In the event of a sale of Shares by the Investor, unless such requirement is waived by the Company in writing, the
Investor must also deliver to the Company's transfer agent, with a copy to the Company, a Certificate of Subsequent Sale substantially in the form attached hereto as Exhibit C, so that the
shares may be properly transferred. 

        (g)  The Company agrees that it shall, immediately prior to the Registration Statement being declared effective, deliver to
its transfer agent an opinion letter of counsel, opining that at any time the Registration Statement is effective, the transfer agent shall issue, in connection with the sale of the Shares,
certificates representing such Shares without restrictive legend, provided the Shares are to be sold pursuant to the prospectus contained in the Registration Statement and the transfer agent receives
a Certificate of Subsequent Sale in the form attached hereto as Exhibit C. Upon receipt of such opinion, the Company shall cause the transfer agent to confirm, for the benefit of the Investor,
that no further opinion of counsel is required at the time of transfer in order to issue such Shares without restrictive legend. 

        In
the event of any sale of the Shares in accordance with this Agreement, the restrictive legend shall be removed and the Company shall issue a certificate without such legend to the
purchaser of any such Shares, if (a) the sale of such Shares is registered under the Registration Statement (including registration pursuant to Rule 416 under the Securities Act);
(b) the holder has provided the Company with an opinion of counsel, in form, substance and scope customary for opinions of counsel in comparable transactions, to the effect that a public sale
or transfer of such Shares may be made without registration under the Securities Act; or (c) such Shares are sold in compliance with Rule 144 under the Securities Act. 

        6.3    Indemnification.    For the purpose of this Section 6.3: 

        (a)  the term "Selling Stockholder" shall include the Investor and each
person, if any, who controls the Investor within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act; 

        (b)  the term "Registration Statement" shall include any final Prospectus,
exhibit, supplement or amendment included in or relating to, and any document incorporated by reference in, the Registration Statement (or deemed to be a part thereof) referred to in
Section 6.1; and 

        (c)  the term "untrue statement" shall include any untrue statement or alleged
untrue statement, or any omission or alleged omission to state in the Registration Statement a 

12

 

material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. 

        (d)  (i)    The Company agrees to indemnify and hold harmless each
Selling Stockholder from and against any losses, claims, damages or liabilities to which such Selling Stockholder may become subject (under the Securities Act or otherwise) insofar as such losses,
claims, damages or liabilities (or actions or proceedings in respect thereof) arise out of, or are based upon (i) any untrue statement of a material fact contained in the Registration
Statement, (ii) any inaccuracy in the representations and warranties of the Company contained in the Agreement or the failure of the Company to perform its obligations hereunder or
(iii) any failure by the Company to fulfill any undertaking included in the Registration Statement, and the Company will reimburse such Selling Stockholder for any reasonable legal expense or
other actual accountable out of pocket expenses reasonably incurred in investigating, defending or preparing to defend any such action, proceeding or claim, provided, however, that the Company shall
not be liable in any such case to the extent that such loss, claim, damage or liability arises out of, or is based upon, an untrue statement made in such Registration Statement in reliance upon and in
conformity with written information furnished to the Company by or on behalf of such Selling Stockholder specifically for use in preparation of the Registration Statement or the failure of such
Selling Stockholder to comply with its covenants and agreements contained in Sections 4.1, 4.2, 4.3 or 6.2 hereof or any statement or omission in any Prospectus that is corrected in any subsequent
Prospectus that was delivered to the Selling Stockholder prior to the pertinent sale or sales by the Selling Stockholder. 

        (ii)  The Investor agrees to indemnify and hold harmless the Company (and each person, if any, who controls the Company within
the meaning of Section 15 of the Securities Act, each officer of the Company who signs the Registration Statement and each director of the Company) from and against any losses, claims, damages
or liabilities to which the Company (or any such officer, director or controlling person) may become subject (under the Securities Act or otherwise), insofar as such losses, claims, damages or
liabilities (or actions or proceedings in respect thereof) arise out of, or are based upon, (i) any failure to comply with the covenants and agreements contained in Section 4.1, 4.2, 4.3
or 6.2 hereof, or (ii) any untrue statement of a material fact contained in the Registration Statement if such untrue statement was made in reliance upon and in conformity with written
information furnished by or on behalf of the Investor specifically for use in preparation of the Registration Statement, and the Investor will reimburse the Company (or such officer, director or
controlling person), as the case may be, for any reasonable legal expense or other actual accountable out-of-pocket expenses reasonably incurred in investigating, defending or
preparing to defend any such action, proceeding or claim. The obligation to indemnify shall be limited to the net amount of the proceeds received by the Investor from the sale of the Shares pursuant
to the Registration Statement. 

      (iii)  Promptly after receipt by any indemnified person of a notice of a claim or the beginning of any action in respect of
which indemnity is to be sought against an indemnifying person pursuant to this Section 6.3, such indemnified person shall notify the indemnifying person in writing of such claim or of the
commencement of such action, but the omission to so notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party under this Section 6.3
(except to the extent that such omission materially and adversely affects the indemnifying party's ability to defend
such action) or from any liability otherwise than under this Section 6.3. Subject to the provisions hereinafter stated, in case any such action shall be brought against an indemnified person,
the indemnifying person shall be entitled to participate therein, and, to the extent that it shall elect by written notice delivered to the indemnified party 

13

 

promptly after receiving the aforesaid notice from such indemnified party, shall be entitled to assume the defense thereof, with counsel reasonably satisfactory to such indemnified person. After
notice from the indemnifying person to such indemnified person of its election to assume the defense thereof (unless it has failed to assume the defense thereof and appoint counsel reasonably
satisfactory to the indemnified party), such indemnifying person shall not be liable to such indemnified person for any legal expenses subsequently incurred by such indemnified person in connection
with the defense thereof, provided, however, that if there exists or shall exist a conflict of interest that would make it inappropriate, in the reasonable opinion of counsel to the indemnified
person, for the same counsel to represent both the indemnified person and such indemnifying person or any affiliate or associate thereof, the indemnified person shall be entitled to retain its own
counsel at the expense of such indemnifying person; provided, however, that no indemnifying person shall be responsible for the fees and expenses of more than one separate counsel (together with
appropriate local counsel) for all indemnified parties. In no event shall any indemnifying person be liable in respect of any amounts paid in settlement of any action unless the indemnifying person
shall have approved the terms of such settlement; provided that such consent shall not be unreasonably withheld. No indemnifying person shall, without the prior written consent of the indemnified
person, effect any settlement of any pending or threatened proceeding in respect of which any indemnified person is or could reasonably have been a party and indemnification could have been sought
hereunder by such indemnified person, unless such settlement includes an unconditional release of such indemnified person from all liability on claims that are the subject matter of such proceeding. 

        (iv)  If the indemnification provided for in this Section 6.3 is unavailable to or insufficient to hold harmless an
indemnified party under subsection (d)(i) or (d)(ii) above in respect of any losses, claims, damages or liabilities (or actions or proceedings in respect thereof) referred to therein,
then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such
proportion as is appropriate to reflect the relative fault of the Company on the one hand and the Investor on the other in connection with the statements or omissions or other matters which resulted
in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative fault shall be determined by reference to, among
other things, in the case of an untrue statement, whether the untrue statement relates to information supplied by the Company on the one hand or the Investor on the other and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent such untrue statement. The Company and the Investor agree that it would not be just and equitable if contribution
pursuant to this subsection (d) were determined by pro rata allocation (even if the Investors were treated as one entity for such purpose) or by any other method of allocation which does not
take into account the equitable considerations referred to above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities
(or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. Notwithstanding the provisions of this subsection (d), the Investor shall not be required to contribute any amount in excess of the amount by which
the gross amount received by the Investor from the sale of the Shares to which such loss relates exceeds the amount of any damages which the Investor has otherwise been required to pay by reason of
such untrue statement. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who 

14

 

was not guilty of such fraudulent misrepresentation. The Investors' obligations in this subsection to contribute are several in proportion to their sales of Shares to which such loss relates and not
joint. 

        (v)  The parties to this Agreement hereby acknowledge that they are sophisticated business persons who were represented by
counsel during the negotiations regarding the provisions hereof including, without limitation, the provisions of this Section 6.3, and are fully informed regarding said provisions. They further
acknowledge that the provisions of this Section 6.3 fairly allocate the risks in light of the ability of the parties to investigate the Company and its business in order to assure that adequate
disclosure is made in the Registration Statement as required by the Securities Act and the Exchange Act. 

        6.4    Termination of Conditions and Obligations.    The conditions precedent imposed by Section 4 or this
Section 6 upon the transferability of the Shares shall cease and terminate as to any particular number of the Shares when such Shares shall have been effectively registered under the Securities
Act and sold or otherwise disposed of in accordance with the intended method of disposition set forth in the Registration Statement covering such Shares or at such time as an opinion of counsel
satisfactory to the Company shall have been rendered to the effect that such conditions are not necessary in order to comply with the Securities Act. 

        6.5    Information Available.    So long as the Registration Statement is effective covering the resale of Shares
owned by the Investor, the Company will furnish (or to the extent such information is available electronically through the Company's filings with the SEC, the Company will make available) to the
Investor: 

        (a)  as soon as practicable after it is available, one copy of (i) its Annual Report to Stockholders (which Annual
Report shall contain financial statements audited in accordance with generally accepted accounting principles by a national firm of certified public accountants) and (ii) if not included in
substance in the Annual Report to Stockholders, its Annual Report on Form 10-K (the foregoing, in each case, excluding exhibits); 

        (b)  upon the reasonable request of the Investor, all exhibits excluded by the parenthetical to subparagraph (a)(ii) of
this Section 6.5 as filed with the SEC and all other information that is made available to stockholders; and 

        (c)  upon the reasonable request of the Investor, an adequate number of copies of the Prospectuses to supply to any other
party requiring such Prospectuses; and the Company, upon the reasonable request of the Investor, will meet with the Investor or a representative thereof at the Company's headquarters to discuss all
information relevant for disclosure in the Registration Statement covering the Shares and will otherwise reasonably cooperate with the Investor conducting an investigation for the purpose of reducing
or eliminating the Investor's exposure to liability under the Securities Act, including the reasonable production of information at the Company's headquarters; provided, that the Company shall
not be required to disclose any confidential information to or meet at its headquarters with the Investor until and unless the Investor shall have entered into a confidentiality agreement in form and
substance reasonably satisfactory to the Company with the Company with respect thereto. 

        6.6    Public Statements.    The Company agrees to disclose the existence of the Offering and the material terms
thereof within three (3) business days after its receipt of the Investor's executed Agreement. The Company will not issue any public statement, press release or any other public disclosure
listing Investor as one of the purchasers of the Shares without Investor's prior written consent, except as may be required by applicable law or rules of any exchange on which the Company's securities
are listed. 

        7.    Notices.    All notices, requests, consents and other communications hereunder shall be in writing, shall be
mailed (A) if within domestic United States by first-class registered or certified airmail, 

15

 

or nationally recognized overnight express courier, postage prepaid, or by facsimile, or (B) if delivered from outside the United States, by International Federal Express (or comparable
service) or facsimile, and shall be deemed given (i) if delivered by first-class registered or certified mail domestic, three business days after so mailed, (ii) if delivered by
nationally recognized overnight carrier, one (1) business day after so mailed, (iii) if delivered by International Federal Express (or comparable service), two (2) business days
