                                     ANNEX I

                   TERMS AND CONDITIONS FOR PURCHASE OF SHARES

1.   Authorization and Sale of the Shares. Subject to the terms and conditions
     of this Agreement, the Company has authorized the sale of 80,000 Shares.
     The Company reserves the right to increase or decrease this number.

2.   Agreement to Sell and Purchase the Shares; Subscription Date.

2.1  At the Closing (as defined in Section 3), the Company will sell to the
     Investor, and the Investor will purchase from the Company, upon the terms
     and conditions hereinafter set forth, the number of Shares set forth on the
     signature page hereto at the purchase price set forth on such signature
     page.

2.2  The Company proposes to enter into this same form of Stock Purchase
     Agreement with certain other investors (the "Other Investors") and expects
     to complete sales of Shares to them. (The Investor and the Other Investors
     are hereinafter sometimes collectively referred to as the "Investors," and
     this Agreement and the Stock Purchase Agreements executed by the Other
     Investors are hereinafter sometimes collectively referred to as the
     "Agreements.") The Company will accept executed Agreements from Investors
     for the purchase of Shares commencing upon the date on which the Company
     provides the Investors with the proposed purchase price per Share and
     concluding upon the date (the "Subscription Date") on which the Company has
     executed Agreements with Investors for the purchase of Shares in the amount
     of at least $2,000,000.

3.   Delivery of the Shares at Closing. The completion of the purchase and sale
     of the Shares (the "Closing") shall occur at the offices of the Company in
     Chantilly, VA on September 28, 2000 (the "Closing Date"). At the Closing,
     the Company shall deliver to the Investor one or more stock certificates
     representing the number of Shares set forth on the signature page hereto,
     each such certificate to be issued in the name of the Investor or, if so
     indicated on the signature page hereto, in the name of a nominee designated
     by the Investor.

          The Company's obligation to issue the Shares to the Investor shall be
     subject to the following conditions, any one or more of which may be waived
     by the Company: (a) receipt by the Company of the purchase price for the
     Shares being purchased hereunder as set forth on the signature page hereto;
     (b) completion of the purchases and sales under the Agreements with the
     Other Investors; and (c) the accuracy of the representations and warranties
     made by the Investors and the fulfillment of those undertakings of the
     Investors to be fulfilled prior to the Closing.

4.   Representations, Warranties and Covenants of the Company. The Company
     hereby represents and warrants to, and covenants with, the Investor, as
     follows:

4.1  Organization. The Company is duly incorporated and validly existing and in
     good standing under the laws
<PAGE>
          of the jurisdiction of its organization. Each of the Company and its
     Subsidiaries (as defined in Rule 405 under the Securities Act of 1933, as
     amended (the "Securities Act")) has full power and authority to own,
     operate and occupy its properties and to conduct its business as presently
     conducted and as described in the confidential offering memorandum, dated
     September 21, 2000 distributed in connection with the sale of the Shares
     (including the documents incorporated by reference therein, the "Placement
     Memorandum") and is registered or qualified to do business and in good
     standing in each jurisdiction in which it owns or leases property or
     transacts business and where the failure to be so qualified would have a
     material adverse effect upon the business, financial condition, properties
     or operations of the Company and its Subsidiaries, considered as one
     enterprise ("Material Adverse Effect"), and no proceeding has been
     instituted in any such jurisdiction revoking, limiting or curtailing, or
     seeking to revoke, limit or curtail, such power and authority or
     qualification.

4.2  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).

4.3  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) conflict
     with or constitute a violation of, or default (with the passage of time or
     otherwise) under, (i) any material bond, debenture, note or other evidence
     of indebtedness, or any material lease, contract, indenture, mortgage, deed
     of trust, loan agreement, joint venture or other agreement or instrument to
     which the Company or any Subsidiary is a party or by which it or any of its
     Subsidiaries or their respective properties are bound, (ii) the charter,
     by-laws or other organizational documents of the Company or any Subsidiary,
     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 Subsidiary 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 material lien,
     encumbrance, claim, security interest or restriction whatsoever upon any of
     the material properties or assets of the Company or any Subsidiary or a
     material acceleration of indebtedness pursuant to any obligation, agreement
     or condition contained in any material bond, debenture, note or any other
     material evidence of indebtedness or any material indenture, mortgage, deed
     of trust or any other material agreement or instrument to which the Company
     or any Subsidiary is a party or by which any of them is bound or to which
     any of the material property or assets of the Company or any Subsidiary 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 and the valid
     issuance and sale of the Shares to be sold pursuant to the Agreements,
     other than such as have been made or obtained, except for any securities
     filings required to be made under federal or state securities laws, and
     except where any failure to obtain any of the foregoing would not have a
     Material Adverse Effect.

4.4  Capitalization. The capitalization of the Company as of June 30, 2000 is as
     set forth in the Placement Memorandum (excluding unvested options and
     treasury shares). The Company has not issued any capital stock since that
     date other than pursuant to (i) options granted or to be granted pursuant
     to the Company's

          1998 Amended Stock Option Plan and (ii) a certain Agreement with
     Christian Network Inc. and David Sams, Inc. for payment in lieu of cash for
     advertising services rendered. The
<PAGE>
     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. Except for
     any actions required to be taken by the Company in connection with the
     settlement of claims described in the Placement Memorandum, 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
     all 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 as set forth in or contemplated by the Placement
     Memorandum, 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 Subsidiary, or any contract,
     commitment, agreement, understanding or arrangement of any kind to which
     the Company is a party and relating to the issuance or sale of any capital
     stock of the Company or any Subsidiary, any such convertible or
     exchangeable securities or any such rights, warrants or options. Without
     limiting the foregoing and other than certain registration rights
     previously granted by the Company to certain Company shareholders which may
     (under certain circumstances) delay the registration of the Investors'
     Shares, no preemptive right, co-sale right, right of first refusal or other
     similar right exists with respect to the issuance and sale of the Shares.
     The Company owns the entire equity interest in each of its Subsidiaries,
     free and clear of any pledge, lien, security interest, encumbrance or
     claim, other than as described in the Placement Memorandum. Except as
     disclosed in the Placement Memorandum, there are no stockholders
     agreements, voting agreements or other similar agreements with respect to
     the Common Stock to which the Company is a party.

4.5  Legal Proceedings. There is no material legal or governmental proceeding
     pending to which the Company or any Subsidiary is a party or of which the
     business or property of the Company or any Subsidiary is subject that is
     not disclosed in the Placement Memorandum.

4.6  No Violations. Neither the Company nor any Subsidiary is in violation of
     its charter, bylaws or other organizational document, 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 Subsidiary, which violation, individually or in the
     aggregate, would be reasonably likely to have a Material Adverse Effect, or
     is in default (and there exists no condition which, with the passage of
     time or otherwise, would constitute a default) in the performance of any
     material bond, debenture, note or any other evidence of indebtedness, or in
     any indenture, mortgage, deed of trust or any other material agreement or
     instrument to which the Company or any Subsidiary is a party or by which
     the Company or any Subsidiary is bound or by which the properties of the
     Company or any Subsidiary are bound, which would be reasonably likely to
     have a Material Adverse Effect.

4.7  Governmental Permits, Etc. 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 and as
     described in the Placement Memorandum except where the failure to currently
     possess could not reasonably be expected to have a Material Adverse Effect.

4.8  Intellectual Property.

     (a)  The Company has exclusive ownership or a valid license to use all
          patent, copyright, trade secret, trademark or other proprietary rights
          that are used in the business of the Company and are material to the
          Company (collectively, "Intellectual Property") other than
          Intellectual Property generally available on commercial terms from
          other sources. All of such material patents, registered trademarks and
          registered copyrights have been duly registered in, filed in or issued
          by the United States Patent and Trademark Office, the United States
          Register of Copyrights or the corresponding offices of other
          jurisdictions and have been maintained and renewed in accordance with
          all applicable provisions of law and administrative regulations in the
          United States and all such jurisdictions.
<PAGE>
     (b)  All material licenses or other material agreements under which (i) the
          Company is granted rights in Intellectual Property, other than
          Intellectual Property generally available on commercial terms from
          other sources, and (ii) the Company has granted rights to others in
          Intellectual Property owned or licensed by the Company, are in full
          force and effect and there is no material default by the Company
          thereto.

     (c)  No proceedings have been instituted or are pending which challenge in
          a material manner the rights of the Company in respect to the
          Company's right to the use of the Intellectual Property. The Company
          has the right to use, free and clear of material claims or rights of
          other persons, all of its customer lists, designs, computer software,
          systems, data compilations, and other information that are required
          for its products or its business as presently conducted.

     (d)  The Company believes it has taken such reasonable steps as are
          required in accordance with sound business practice and business
          judgment to establish and preserve its ownership of all material
          copyright, trade secret and other proprietary rights with respect to
          its products and technology.

     (e)  To the knowledge of the Company, the present business, activities and
          products of the Company do not infringe any intellectual property of
          any other person, except where such infringement would not have a
          Material Adverse Effect on the Company. No material proceeding
          charging the Company with infringement of any adversely held
          Intellectual Property has been filed. To the knowledge of the Company,
          the Company is not making unauthorized use of any material
          confidential information or trade secrets of any third party. To the
          Company's knowledge, the activities of the Company or any of its
          employees on behalf of the Company do not violate any material
          agreements or arrangements known to the Company which any such
          employees have with other persons, if any.

4.9  Financial Statements. The financial statements of the Company and the
     related notes contained in the Placement Memorandum present fairly, in
     accordance with generally accepted accounting principles, the financial
     position of the Company and its Subsidiaries as of the dates indicated.
     Such financial statements (including the related notes) have been prepared
     in accordance with generally accepted accounting principles applied on a
     consistent basis throughout the periods therein specified. The other
     financial information contained in the Placement Memorandum has been
     prepared on a basis consistent with the financial statements of the
     Company.

4.10 No Material Adverse Change. Except as disclosed in the Placement
     Memorandum, since June 30, 2000, there has not been any Material Adverse
     Effect affecting the Company, (ii) any obligation, direct or contingent,
     that is material to the Company and its Subsidiaries considered as one
     enterprise, incurred by the Company, except obligations incurred in the
     ordinary course of business, (iii) any dividend or distribution of any kind
     declared, paid or made on the capital stock of the Company or any of its
     Subsidiaries, or (iv) any loss or damage (whether or not insured) to the
     physical property of the Company or any of its Subsidiaries which has been
     sustained which has a Material Adverse Effect.

4.11 Disclosure. The information contained in the Placement Memorandum as of the
     date of such information did 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.

4.12 NASDAQ Compliance. The Company's Common Stock is registered pursuant to
     Section 12(g) of the Exchange Act (as defined in Section 4.13) and is
     listed on the Nasdaq National Market of the Nasdaq Stock Market (the
     "Nasdaq Stock Market"), and the Company has taken no action designed to, or
     likely to have the effect of, terminating the registration of the Common
     Stock under the Exchange Act or de-listing the Common Stock from the Nasdaq
     Stock Market, nor has the Company received any notification within the 12
     months preceding the date of this Agreement that the Securities and
     Exchange Commission (the "SEC") or the National Association of Securities
     Dealers, Inc. ("NASD") is contemplating terminating such registration or
     listing.
<PAGE>
4.13 Reporting Status. The Company has filed in a timely manner all documents
     that the Company was required to file under the Securities Exchange Act of
     1934, as amended (the "Exchange Act") during the 12 months preceding the
     date of this Agreement. The following documents complied in all material
     respects with the SEC's requirements as of their respective filing dates,
     and the information contained therein as of the date thereof did 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 where they were made not
     misleading:

     (a)  Quarterly Report on Form 10-Q for the Quarter Ended June 30, 2000,

     violation of applicable law, take, any action designed to or that might
     reasonably be expected to cause or result in manipulation of the price of
     the Common Stock to facilitate the sale or resale of the Shares.

5.   Representations, Warranties and Covenants of the Investor.

5.1  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 and the Investor is also knowledgeable,
     sophisticated and experienced in making, and is qualified to make decisions
     with respect to, investments in shares presenting an investment decision
     like that involved in the purchase of the Shares, including investments in
     securities issued by the Company and investments in comparable companies,
     and has requested, received, reviewed and considered all information it
     deemed relevant in making an informed decision to purchase the Shares; (ii)
     the Investor is acquiring the number of Shares set forth on the signature
     page hereto in the ordinary course of its business and for its own account
     for investment only and with no present intention of distributing any of
     such Shares and no arrangement or understanding exists with any other
     person regarding the distribution of such Shares; (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 on the signature page hereto for use in preparation of the
     Registration Statement (as defined in Section 7.1) and the answers thereto
     are true and correct as of the date hereof and will be true and correct as
     of the Closing Date; (v) the Investor will notify the Company immediately
     of any change in any of such information until such time as the Investor
     has sold all of its Shares or until the Company is no longer required to
     keep the Registration Statement effective; and (vi) the Investor has, in
     connection with its decision to purchase the number of Shares set forth on
     the signature page hereto, relied only upon the Placement Memorandum and
     the representations and warranties of the Company contained herein.
<PAGE>
     Investor understands that its acquisition of the Shares has not been
     registered under the Securities Act or registered or qualified under any
     state securities law in reliance on specific exemptions therefrom, which
     exemptions may depend upon, among other things, the bona fide nature of the
     Investor's investment intent as expressed herein. Investor has completed or
     caused to be completed and delivered to the Company the Investor
     Questionnaire attached as Exhibit E to the Placement Memorandum, which
     questionnaire is true and correct in all material respects.

5.2  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
     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 where action for that purpose is
     required. Each Investor outside the United States will comply with all
     applicable laws and regulations in each foreign jurisdiction in which it
     purchases, offers, sells or delivers Shares or has in its possession or
     distributes any offering material, in all cases at its own expense.

5.3  The Investor hereby covenants with the Company not to make any sale of the
     Shares without complying with the provisions of this Agreement, including
     Section 7.2 hereof, and without effectively causing the prospectus delivery
     requirement under the Securities Act to be satisfied, 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 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.

5.4  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.

5.5  Investor will not, prior to the effectiveness of the Registration
     Statement, sell, offer to sell, solicit offers to buy, dispose of, loan,
     pledge or grant any right with respect to (collectively, a "Disposition"),
     the Common Stock of the Company, nor will Investor engage in any hedging or
     other transaction which is designed to or could reasonably be expected to
     lead to or result in a Disposition of Common Stock of the Company by the
     Investor or any other person or entity. Such prohibited hedging or other
     transactions would include, without limitation, effecting any short sale or
     having in effect any short position (whether or not such sale or position
     is against the box and regardless of when such position was entered into)
     or any purchase, sale or grant of any right (including, without limitation,
     any put or call option) with respect to the Common Stock of the Company or
     with respect to any security (other than a broad-based market basket or
     index) that includes, relates to or derives any significant part of its
     value from the Common Stock of the Company.

5.6  The Investor agrees that if the Company engages in an underwritten public
     offering for the sale by the Company of shares of Common Stock, during the
     one-year period following the Closing Date and thereafter so long as the
     Investor owns more than one percent (1%) of the Common Stock, the Investor
     will, if so requested by the managing underwriter for such offering,
     execute and deliver to such managing underwriter a "lock-up" letter in a
     form acceptable to such managing underwriter. The obligations of and
     restrictions on the Investor under such letter shall be in effect for a
     maximum of 180 days as specified by the managing underwriter.
<PAGE>
5.7  The Investor understands that nothing in the Placement Memorandum, 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.

6.   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.

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

7.1  Registration Procedures and Expenses.   The Company shall:

     (a)  subject to receipt of necessary information from the Investors,
          prepare and effectuate with the SEC, within ninety (90) days after the
          Closing Date, a registration statement on Form S-3 or other Form, as
          determined by the Issuer in accordance with SEC regulations (the
          "Registration Statement"), to enable the resale of the Shares by the
          Investors from time to time. If the Company does not deliver on this
          term, a penalty of $500 per day payable in cash or stock, at the
          Conversion Price, at the discretion of the Issuer, will be due and
          payable to the Purchaser.

     (b)  use its reasonable 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.

     (c)  furnish to the Investor with respect to the Shares registered under
          the Registration Statement such number of copies of the Registration
          Statement, Prospectuses and 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, provided, however, that 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;

     (d)  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;

     (e)  bear all expenses in connection with the procedures in paragraph (a)
          through (d) of this Section 7.1 and the registration of the Shares
          pursuant to the Registration Statement; and
<PAGE>
     (f)  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 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.

               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,
          provided, however, that if the Company receives notification from the
          SEC that the Investor is deemed an underwriter, then the period by
          which the Company is obligated to submit an acceleration request to
          the SEC shall be extended to the earlier of (i) the 90th day after
          such SEC notification, or (ii) 120 days after the initial filing of
          the Registration Statement with the SEC.

7.2  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 except as contemplated
          in the Registration Statement referred to in Section 7.1 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 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
          7.2(b)(i); and (iii) inform each Investor that the Company has
          complied with its obligations in Section 7.2(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
          7.2(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 a 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 a 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
<PAGE>
          the circumstances under which they were made, not misleading; then the
          Company shall 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 efforts to cause the use of the Prospectus so suspended, to
          be resumed as soon as reasonably practicable.

     (d)  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 (or arranges for delivery of such to the transferee's
          broker). Upon receipt of a written request therefor, the Company has
          agreed to provide an adequate number of current Prospectuses to the
          Investor and to supply copies to any other parties requiring such
          Prospectuses.

     (e)  In the event of a sale of Shares by the Investor, 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 as Exhibit H to the Placement Memorandum, so that the Shares
          may be properly transferred.

7.3  Indemnification.  For the purpose of this Section 7.3:

     (i)  the term "Selling Stockholder" shall include the Investor and any
          affiliate of such Investor;

     (ii) the term "Registration Statement" shall include any final Prospectus,
          exhibit, supplement or amendment included in or relating to the
          Registration Statement referred to in Section 7.1; and

     (iii) 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 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.

          (a)   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, or (ii) 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 or other 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 or the failure of such Selling
          Stockholder to comply with its covenants and agreements contained in
          Sections 5 or 7.2 hereof or any statement or omission in any
          Prospectus that is corrected in any subsequent Prospectus that was
          delivered to the Investor prior to the pertinent sale or sales by the
          Investor.

          (b)   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
<PAGE>
          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 Sections 5 or
          7.2 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, and the Investor will reimburse the
          Company (or such officer, director or controlling person), as the case
          may be, for any legal or other expenses reasonably incurred in
          investigating, defending or preparing to defend any such action,
          proceeding or claim.

          (c)  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
          7.3, 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 7.3 (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 7.3.
          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 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, 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 reasonable 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 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.

          (d)   If the indemnification provided for in this Section 7.3 is
          unavailable to or insufficient to hold harmless an indemnified party
          under subsection (a) or (b) 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 Investors 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 an 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 Investors 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
<PAGE>
          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), no
          Investor shall 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 such 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
          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.

          (e)   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 7.3, and are fully informed
          regarding said provisions. They further acknowledge that the
          provisions of this Section 7.3 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 Act and the Exchange Act.
          The parties are advised that federal or state public policy as
          interpreted by the courts in certain jurisdictions may be contrary to
          certain of the provisions of this Section 7.3, and the parties hereto
          hereby expressly waive and relinquish any right or ability to assert
          such public policy as a defense to a claim under this Section 7.3 and
          further agree not to attempt to assert any such defense.

7.4  Termination of Conditions and Obligations. The conditions precedent imposed
     by Section 5 or this Section 7 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.

7.5  Information Available. So long as the Registration Statement is effective
     covering the resale of Shares owned by the Investor, the Company will
     furnish 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; and

     (b)  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 cooperate with any Investor conducting an investigation for
          the purpose of reducing or eliminating such 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 any 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.

2.3  The Company proposes to enter into this same form of Stock Purchase
     Agreement with certain other investors (the "Other Investors") and expects
     to complete sales of Shares to them. (The Investor and the Other Investors

     Shares being purchased hereunder as set forth on the signature page hereto;
     (b) completion of the purchases and sales under the Agreements with the
     Other Investors; and (c) the accuracy of the representations and warranties
     made by the Investors and the fulfillment of those undertakings of the
     Investors to be fulfilled prior to the Closing.

4.   Representations, Warranties and Covenants of the Company. The Company
     hereby represents and warrants to, and covenants with, the Investor, as
     follows:

4.2  Organization. The Company is duly incorporated and validly existing and in
     good standing under the laws
<PAGE>
          of the jurisdiction of its organization. Each of the Company and its
     Subsidiaries (as defined in Rule 405 under the Securities Act of 1933, as
     amended (the "Securities Act")) has full power and authority to own,
     operate and occupy its properties and to conduct its business as presently
     conducted and as described in the confidential offering memorandum, dated
     December 14, 2001 distributed in connection with the sale of the Shares
     (including the documents incorporated by reference therein, the "Placement
     Memorandum") and is registered or qualified to do business and in good
     standing in each jurisdiction in which it owns or leases property or
     transacts business and where the failure to be so qualified would have a
     material adverse effect upon the business, financial condition, properties
     or operations of the Company and its Subsidiaries, considered as one
     enterprise ("Material Adverse Effect"), and no proceeding has been
     instituted in any such jurisdiction revoking, limiting or curtailing, or
     seeking to revoke, limit or curtail, such power and authority or
     qualification.

4.2  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).

4.3  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) conflict
     with or constitute a violation of, or default (with the passage of time or
     otherwise) under, (i) any material bond, debenture, note or other evidence
     of indebtedness, or any material lease, contract, indenture, mortgage, deed
     of trust, loan agreement, joint venture or other agreement or instrument to
     which the Company or any Subsidiary is a party or by which it or any of its
     Subsidiaries or their respective properties are bound, (ii) the charter,
     by-laws or other organizational documents of the Company or any Subsidiary,
     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 Subsidiary 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 material lien,
     encumbrance, claim, security interest or restriction whatsoever upon any of
     the material properties or assets of the Company or any Subsidiary or a
     material acceleration of indebtedness pursuant to any obligation, agreement
     or condition contained in any material bond, debenture, note or any other
     material evidence of indebtedness or any material indenture, mortgage, deed
     of trust or any other material agreement or instrument to which the Company
     or any Subsidiary is a party or by which any of them is bound or to which
     any of the material property or assets of the Company or any Subsidiary 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 and the valid
     issuance and sale of the Shares to be sold pursuant to the Agreements,
     other than such as have been made or obtained, except for any securities
     filings required to be made under federal or state securities laws, and
     except where any failure to obtain any of the foregoing would not have a
     Material Adverse Effect.

4.5  Capitalization. The capitalization of the Company as of September 30, 2001
     is as set forth in the Placement Memorandum (excluding unvested options and
     treasury shares). The Company has not issued any capital stock since that
     date other than pursuant to options granted or to be granted pursuant to
     the Company's 1998 Amended Stock Option Plan. 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. Except for any actions
     required to be taken by the Company in connection with the settlement of
<PAGE>
     claims described in the Placement Memorandum, 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 all
     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 as set forth in or contemplated by the Placement
     Memorandum, 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 Subsidiary, or any contract,
     commitment, agreement, understanding or arrangement of any kind to which
     the Company is a party and relating to the issuance or sale of any capital
     stock of the Company or any Subsidiary, any such convertible or
     exchangeable securities or any such rights, warrants or options. Without
     limiting the foregoing and other than certain registration rights
     previously granted by the Company to certain Company shareholders which may
     (under certain circumstances) delay the registration of the Investors'
     Shares, no preemptive right, co-sale right, right of first refusal or other
     similar right exists with respect to the issuance and sale of the Shares.
     The Company owns the entire equity interest in each of its Subsidiaries,
     free and clear of any pledge, lien, security interest, encumbrance or
     claim, other than as described in the Placement Memorandum. Except as
     disclosed in the Placement Memorandum, there are no stockholders
     agreements, voting agreements or other similar agreements with respect to
     the Common Stock to which the Company is a party.

4.5  Legal Proceedings. There is no material legal or governmental proceeding
     pending to which the Company or any Subsidiary is a party or of which the
     business or property of the Company or any Subsidiary is subject that is
     not disclosed in the Placement Memorandum.

4.6  No Violations. Neither the Company nor any Subsidiary is in violation of
     its charter, bylaws or other organizational document, 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 Subsidiary, which violation, individually or in the
     aggregate, would be reasonably likely to have a Material Adverse Effect, or
     is in default (and there exists no condition which, with the passage of
     time or otherwise, would constitute a default) in the performance of any
     material bond, debenture, note or any other evidence of indebtedness, or in
     any indenture, mortgage, deed of trust or any other material agreement or
     instrument to which the Company or any Subsidiary is a party or by which
     the Company or any Subsidiary is bound or by which the properties of the
     Company or any Subsidiary are bound, which would be reasonably likely to
     have a Material Adverse Effect.

4.7  Governmental Permits, Etc. 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 and as
     described in the Placement Memorandum except where the failure to currently
     possess could not reasonably be expected to have a Material Adverse Effect.

4.8  Intellectual Property.

     (a)  The Company has exclusive ownership or a valid license to use all
          patent, copyright, trade secret, trademark or other proprietary rights
          that are used in the business of the Company and are material to the
          Company (collectively, "Intellectual Property") other than
          Intellectual Property generally available on commercial terms from
          other sources. All of such material patents, registered trademarks and
          registered copyrights have been duly registered in, filed in or issued
          by the United States Patent and Trademark Office, the United States
          Register of Copyrights or the corresponding offices of other
          jurisdictions and have been maintained and renewed in accordance with
          all applicable provisions of law and administrative regulations in the
          United States and all such jurisdictions.

     (b)  All material licenses or other material agreements under which (i) the
          Company is granted rights in Intellectual Property, other than
          Intellectual Property generally available on commercial terms from
<PAGE>
          other sources, and (ii) the Company has granted rights to others in
          Intellectual Property owned or licensed by the Company, are in full
          force and effect and there is no material default by the Company
          thereto.

     (c)  No proceedings have been instituted or are pending which challenge in
          a material manner the rights of the Company in respect to the
          Company's right to the use of the Intellectual Property. The Company
          has the right to use, free and clear of material claims or rights of
          other persons, all of its customer lists, designs, computer software,
          systems, data compilations, and other information that are required
          for its products or its business as presently conducted.

     (d)  The Company believes it has taken such reasonable steps as are
          required in accordance with sound business practice and business
          judgment to establish and preserve its ownership of all material
          copyright, trade secret and other proprietary rights with respect to
          its products and technology.

     (e)  To the knowledge of the Company, the present business, activities and
          products of the Company do not infringe any intellectual property of
          any other person, except where such infringement would not have a
          Material Adverse Effect on the Company. No material proceeding
          charging the Company with infringement of any adversely held
          Intellectual Property has been filed. To the knowledge of the Company,
          the Company is not making unauthorized use of any material
          confidential information or trade secrets of any third party. To the
          Company's knowledge, the activities of the Company or any of its
          employees on behalf of the Company do not violate any material
          agreements or arrangements known to the Company which any such
          employees have with other persons, if any.

4.9  Financial Statements. The financial statements of the Company and the
     related notes contained in the Placement Memorandum present fairly, in
     accordance with generally accepted accounting principles, the financial
     position of the Company and its Subsidiaries as of the dates indicated.
     Such financial statements (including the related notes) have been prepared
     in accordance with generally accepted accounting principles applied on a
     consistent basis throughout the periods therein specified. The other
     financial information contained in the Placement Memorandum has been
     prepared on a basis consistent with the financial statements of the
     Company.

4.10 No Material Adverse Change. Except as disclosed in the Placement
     Memorandum, since September 30, 2001, there has not been any Material
     Adverse Effect affecting the Company, (ii) any obligation, direct or
     contingent, that is material to the Company and its Subsidiaries considered
     as one enterprise, incurred by the Company, except obligations incurred in
     the ordinary course of business, (iii) any dividend or distribution of any
     kind declared, paid or made on the capital stock of the Company or any of
     its Subsidiaries, or (iv) any loss or damage (whether or not insured) to
     the physical property of the Company or any of its Subsidiaries which has
     been sustained which has a Material Adverse Effect.

4.11 Disclosure. The information contained in the Placement Memorandum as of the
     date of such information did 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.

4.12 NASDAQ Compliance. The Company's Common Stock is registered pursuant to
     Section 12(g) of the Exchange Act (as defined in Section 4.13) and is
     listed on the Nasdaq SmallCap Market of the Nasdaq Stock Market (the
     "Nasdaq Stock Market"), and the Company has taken no action designed to, or
     likely to have the effect of, terminating the registration of the Common
     Stock under the Exchange Act or de-listing the Common Stock from the Nasdaq
     Stock Market, nor has the Company received any notification within the 12
     months preceding the date of this Agreement that the Securities and
     Exchange Commission (the "SEC") or the National Association of Securities
     Dealers, Inc. ("NASD") is contemplating terminating such registration or
     listing.

     respects with the SEC's requirements as of their respective filing dates,
     and the information contained therein as of the date thereof did not
     contain an untrue statement of a material fact or omit to state a material

     therein in light of the circumstances under where they were made not
     misleading:

5.   Representations, Warranties and Covenants of the Investor.

5.1  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 and the Investor is also knowledgeable,
     sophisticated and experienced in making, and is qualified to make decisions
     with respect to, investments in shares presenting an investment decision
     like that involved in the purchase of the Shares, including investments in
     securities issued by the Company and investments in comparable companies,
     and has requested, received, reviewed and considered all information it
     deemed relevant in making an informed decision to purchase the Shares; (ii)
     the Investor is acquiring the number of Shares set forth on the signature
     page hereto in the ordinary course of its business and for its own account
     for investment only and with no present intention of distributing any of
     such Shares and no arrangement or understanding exists with any other
     person regarding the distribution of such Shares; (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 on the signature page hereto for use in preparation of the
     Registration Statement (as defined in Section 7.1) and the answers thereto
     are true and correct as of the date hereof and will be true and correct as
     of the Closing Date; (v) the Investor will notify the Company immediately
     of any change in any of such information until such time as the Investor
     has sold all of its Shares or until the Company is no longer required to
     keep the Registration Statement effective; and (vi) the Investor has, in
     connection with its decision to purchase the number of Shares set forth on
     the signature page hereto, relied only upon the Placement Memorandum and
     the representations and warranties of the Company contained herein.
     Investor understands that its acquisition of the Shares has not been
     registered under the Securities Act or registered or qualified under any
     state securities law in reliance on specific exemptions therefrom, which
     exemptions may depend upon, among other things, the bona fide nature of the
<PAGE>
     Investor's investment intent as expressed herein. Investor has completed or
     caused to be completed and delivered to the Company the Investor
     Questionnaire attached as Exhibit E to the Placement Memorandum, which
     questionnaire is true and correct in all material respects.

5.4  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
     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 where action for that purpose is
     required. Each Investor outside the United States will comply with all
     applicable laws and regulations in each foreign jurisdiction in which it
     purchases, offers, sells or delivers Shares or has in its possession or
     distributes any offering material, in all cases at its own expense.

5.5  The Investor hereby covenants with the Company not to make any sale of the
     Shares without complying with the provisions of this Agreement, including
     Section 7.2 hereof, and without effectively causing the prospectus delivery
     requirement under the Securities Act to be satisfied, 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 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.

5.4  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.

5.5  Investor will not, prior to the effectiveness of the Registration
     Statement, sell, offer to sell, solicit offers to buy, dispose of, loan,
     pledge or grant any right with respect to (collectively, a "Disposition"),
     the Common Stock of the Company, nor will Investor engage in any hedging or
     other transaction which is designed to or could reasonably be expected to
     lead to or result in a Disposition of Common Stock of the Company by the
     Investor or any other person or entity. Such prohibited hedging or other
     transactions would include, without limitation, effecting any short sale or
     having in effect any short position (whether or not such sale or position
     is against the box and regardless of when such position was entered into)
     or any purchase, sale or grant of any right (including, without limitation,
     any put or call option) with respect to the Common Stock of the Company or
     with respect to any security (other than a broad-based market basket or
     index) that includes, relates to or derives any significant part of its
     value from the Common Stock of the Company.

5.6  The Investor agrees that if the Company engages in an underwritten public
     offering for the sale by the Company of shares of Common Stock, during the
     one-year period following the Closing Date and thereafter so long as the
     Investor owns more than one percent (1%) of the Common Stock, the Investor
     will, if so requested by the managing underwriter for such offering,
     execute and deliver to such managing underwriter a "lock-up" letter in a
     form acceptable to such managing underwriter. The obligations of and
     restrictions on the Investor under such letter shall be in effect for a
     maximum of 180 days as specified by the managing underwriter.
<PAGE>
5.7  The Investor understands that nothing in the Placement Memorandum, 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.

6.   Survival of Representations, Warranties and Agreements. Notwithstanding any
     investigation made by any party to this Agreement, 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.

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

7.1  Registration Procedures and Expenses. The Company shall:

     (a)  subject to receipt of necessary information from the Investors,
          prepare and effectuate with the SEC, within ninety (90) days after the
          Closing Date, a registration statement on Form S-3 or other Form, as
          determined by the Issuer in accordance with SEC regulations (the
          "Registration Statement"), to enable the resale of the Shares by the
          Investors from time to time. If the Company does not deliver on this
          term, a penalty of $500 per day payable in cash or stock, at the
          Conversion Price, at the discretion of the Issuer, will be due and
          payable to the Purchaser.

     (c)  use its reasonable 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.

     (c)  furnish to the Investor with respect to the Shares registered under
          the Registration Statement such number of copies of the Registration
          Statement, Prospectuses and 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, provided, however, that 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;

     (d)  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;

     (e)  bear all expenses in connection with the procedures in paragraph (a)
          through (d) of this Section 7.1 and the registration of the Shares
          pursuant to the Registration Statement; and

     (f)  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
<PAGE>
          use its 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.

               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,
          provided, however, that if the Company receives notification from the
          SEC that the Investor is deemed an underwriter, then the period by
          which the Company is obligated to submit an acceleration request to
          the SEC shall be extended to the earlier of (i) the 90th day after
          such SEC notification, or (ii) 120 days after the initial filing of
          the Registration Statement with the SEC.

7.2  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 except as contemplated
          in the Registration Statement referred to in Section 7.1 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 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
          7.2(b)(i); and (iii) inform each Investor that the Company has
          complied with its obligations in Section 7.2(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
          7.2(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 a 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 a 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 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
<PAGE>
          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 efforts to cause the use of the Prospectus so suspended, to
          be resumed as soon as reasonably practicable.

     (d)  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 (or arranges for delivery of such to the transferee's
          broker). Upon receipt of a written request therefor, the Company has
          agreed to provide an adequate number of current Prospectuses to the
          Investor and to supply copies to any other parties requiring such
          Prospectuses.

     (e)  In the event of a sale of Shares by the Investor, 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 as Exhibit H to the Placement Memorandum, so that the Shares
          may be properly transferred.

7.3  Indemnification.  For the purpose of this Section 7.3:

     (i)  the term "Selling Stockholder" shall include the Investor and any
          affiliate of such Investor;

     (ii) the term "Registration Statement" shall include any final Prospectus,
          exhibit, supplement or amendment included in or relating to the
          Registration Statement referred to in Section 7.1; and

     (iii) 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 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.

          (a)   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, or (ii) 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 or other 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 or the failure of such Selling
          Stockholder to comply with its covenants and agreements contained in
          Sections 5 or 7.2 hereof or any statement or omission in any
          Prospectus that is corrected in any subsequent Prospectus that was
          delivered to the Investor prior to the pertinent sale or sales by the
          Investor.

          (b)   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
<PAGE>
          agreements contained in Sections 5 or 7.2 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,
          and the Investor will reimburse the Company (or such officer, director
          or controlling person), as the case may be, for any legal or other
          expenses reasonably incurred in investigating, defending or preparing
          to defend any such action, proceeding or claim.

          (c)  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
          7.3, 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 7.3 (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 7.3.
          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 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, 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 reasonable 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 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.

          (d)   If the indemnification provided for in this Section 7.3 is
          unavailable to or insufficient to hold harmless an indemnified party
          under subsection (a) or (b) 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 Investors 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 an 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 Investors 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)
<PAGE>
          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), no Investor shall 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 such 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 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.

          (e)   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 7.3, and are fully informed
          regarding said provisions. They further acknowledge that the
          provisions of this Section 7.3 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 Act and the Exchange Act.
          The parties are advised that federal or state public policy as
          interpreted by the courts in certain jurisdictions may be contrary to
          certain of the provisions of this Section 7.3, and the parties hereto
          hereby expressly waive and relinquish any right or ability to assert
          such public policy as a defense to a claim under this Section 7.3 and
          further agree not to attempt to assert any such defense.

     7.4  Termination of Conditions and Obligations. The conditions precedent
          imposed by Section 5 or this Section 7 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.

     7.5  Information Available. So long as the Registration Statement is
          effective covering the resale of Shares owned by the Investor, the
          Company will furnish 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;
               and

          (b)  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 cooperate with
               any Investor conducting an investigation for the purpose of
               reducing or eliminating such 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 any 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.
