Dear Sirs:

            MiningCo.com, Inc., a corporation organized and existing under the
laws of the State of Delaware (the 'Company'), proposes, subject to the terms
and conditions stated herein, to issue and sell to the several underwriters
named in Schedule I hereto (the 'Underwriters') an aggregate of 3,000,000 shares
(the 'Firm Shares') of its common stock, par value $.001 per share (the 'Common
Stock'), and, for the sole purpose of covering over-allotments in connection
with the sale of the Firm Shares, at the option of the Underwriters, up to an
additional 450,000 shares (the 'Additional Shares') of Common Stock. The Firm
Shares and any Additional Shares purchased by the Underwriters are referred to
herein as the 'Offered Shares.' The Company also proposes to issue and sell
[206,783] shares of Common Stock (the 'Comcast Shares') to Comcast Interactive
Investments, Inc. ('Comcast') pursuant to a Common Stock Purchase Agreement
dated as of February 23, 1999 (the 'Comcast Purchase Agreement'), between the
Company and Comcast. The Offered Shares and the Comcast Shares are collectively
referred to herein as the 'Shares.' The Shares are more fully described in the
Registration Statement referred to below.

      1. REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company represents
and warrants to, and agrees with, the Underwriters that:

            (a) The Company has filed with the Securities and Exchange
      Commission (the 'Commission') a registration statement on Form S-1 (No.
      333-69881), and may have filed an amendment or amendments thereto, for the
      registration of the Offered Shares under the Securities Act of 1933, as
      amended (the 'Act'). Such registration statement, including the
      prospectus, financial statements and schedules, exhibits and all other
      documents filed as a part thereof, as amended at the time of effectiveness
      of the registration statement, including any information deemed to be a
      part thereof as of the time of effectiveness pursuant to paragraph (b) of
      Rule 430A or Rule 434 of the Rules 




      and Regulations of the Commission under the Act (the 'Regulations'), is
      herein called the 'Registration Statement' and the prospectus, in the form
      first filed with the Commission pursuant to Rule 424(b) of the Regulations
      or filed as part of the Registration Statement at the time of
      effectiveness if no Rule 424(b) or Rule 434 filing is required, is herein
      called the 'Prospectus.' The term 'preliminary prospectus' as used herein
      means a preliminary prospectus as described in Rule 430 of the
      Regulations.

            (b) At the time of the effectiveness of the Registration Statement
      or the effectiveness of any post-effective amendment to the Registration
      Statement, when the Prospectus is first filed with the Commission pursuant
      to Rule 424(b) or Rule 434 of the Regulations, when any supplement to or
      amendment of the Prospectus is filed with the Commission and at the
      Closing Date and the Additional Closing Date, if any (as hereinafter
      respectively defined), the Registration Statement and the Prospectus and
      any amendments thereof and supplements thereto complied or will comply in
      all material respects with the applicable provisions of the Act and the
      Regulations and does not or will not contain an untrue statement of a
      material fact and does not or will not omit to state any material fact
      required to be stated therein or necessary in order to make the statements
      therein (i) in the case of the Registration Statement, not misleading and
      (ii) in the case of the Prospectus, in light of the circumstances under
      which they were made, not misleading. When the preliminary prospectus
      dated March 3, 1999 relating to the Offered Shares was first filed with
      the Commission (whether filed as part of the registration statement for
      the registration of the Offered Shares or any amendment thereto or
      pursuant to Rule 424(a) of the Regulations) and when any amendment thereof
      or supplement thereto was first filed with the Commission, such
      preliminary prospectus and any amendments thereof and supplements thereto
      complied in all material respects with the applicable provisions of the
      Act and the Regulations and did not contain an untrue statement of a
      material fact and did not omit to state any material fact required to be
      stated therein or necessary in order to make the statements therein in
      light of the circumstances under which they were made not misleading. No
      representation and warranty is made in this subsection (b), however, with
      respect to any information contained in or omitted from the Registration
      Statement or the Prospectus or any related preliminary prospectus or any
      amendment thereof or supplement thereto in reliance upon and in conformity
      with information furnished in writing to the Company by or on behalf of
      any Underwriter through the Representatives as herein stated expressly for
      use in connection with the preparation thereof. If Rule 434 is used, the
      Company will comply with the requirements of Rule 434.

            (c) KPMG LLP, who have certified the financial statements and
      supporting schedules included in the Registration Statement, are
      independent public accountants as required by the Act and the Regulations.

            (d) Subsequent to the respective dates as of which information is
      given in the Registration Statement and the Prospectus, except as set
      forth in the Registration Statement and the Prospectus, there has been no
      material adverse change or any development involving a prospective
      material adverse change in the business, prospects, properties,
      operations, condition (financial or other) or results of operations of the
      Company, whether or not arising from transactions in the ordinary course
      of business, 


                                       2



      and since the date of the latest balance sheet presented in the
      Registration Statement and the Prospectus, the Company has not incurred or
      undertaken any liabilities or obligations, direct or contingent, whether
      or not arising from transactions in the ordinary course of business, which
      are material to the Company, except for liabilities or obligations that
      are reflected in the Registration Statement and the Prospectus.

            (e) This Agreement, the Comcast Purchase Agreement and the
      transactions contemplated herein and therein have been duly and validly
      authorized by the Company and this Agreement and the Comcast Purchase
      Agreement have been duly and validly executed and delivered by the
      Company.

            (f) The Company is not in violation of its certificate of
      incorporation or by-laws (or other organizational documents) or in default
      in the performance of any obligation, agreement or condition contained in
      any agreement, instrument, franchise, license, permit, judgment, order or
      decree to which the Company is a party or by which it or any of its
      properties or assets is bound, which default would have a material adverse
      effect on the Company's business, prospects, properties, operations,
      condition (financial or other) or results of operations (a 'Material
      Adverse Effect').

            (g) The execution, delivery and performance of this Agreement and
      the Comcast Purchase Agreement and the consummation of the transactions
      contemplated hereby and thereby do not and will not (i) conflict with or
      result in a breach of any of the terms and provisions of, or constitute a
      default (or an event which with notice or lapse of time, or both, would
      constitute a default) under, or result in the creation or imposition of
      any lien, charge or encumbrance upon any property or assets of the Company
      pursuant to, any material agreement, instrument, franchise, license or
      permit to which the Company is a party or by which any of its properties
      or assets may be bound or (ii) violate or conflict with any provision of
      applicable law or the certificate of incorporation or by-laws (or other
      organizational documents) of the Company or (iii) violate or conflict with
      any judgment, decree, order, statute, rule or regulation of any court or
      any public, governmental or regulatory agency or body having jurisdiction
      over the Company or any of its properties or assets, which violation or
      conflict would have a Material Adverse Effect. No consent, approval,
      authorization, order, registration, filing, qualification, license or
      permit of or with any court or any public, governmental or regulatory
      agency or body having jurisdiction over the Company or any of its
      properties or assets is required for the execution, delivery and
      performance of this Agreement or the Comcast Purchase Agreement or the
      consummation of the transactions contemplated hereby and thereby,
      including the issuance, sale and delivery of the Shares to be issued, sold
      and delivered by the Company hereunder and thereunder, except the
      registration under the Act of the Offered Shares and such consents,
      approvals, authorizations, orders, registrations, filings, qualifications,
      licenses and permits as may be required under state securities or Blue Sky
      laws in connection with the purchase and distribution of the Offered
      Shares by the Underwriters. The issuance and sale of the Comcast Shares
      pursuant to the Comcast Purchase Agreement is exempt from the registration
      requirements of the Act by virtue of Section 4(2) of the Act.


                                       3



            (h) All of the outstanding shares of Common Stock are duly and
      validly authorized and issued, fully paid and nonassessable and were not
      issued and are not now in violation of or subject to any preemptive
      rights. The Shares, when issued, delivered and sold in accordance with
      this Agreement or the Comcast Purchase Agreement, as the case may be, will
      be duly and validly issued and outstanding, fully paid and nonassessable,
      and will not have been issued in violation of or be subject to any
      preemptive rights. The Company had, at December 31, 1998, an authorized
      and outstanding capitalization as set forth in the Registration Statement
      and the Prospectus. The Common Stock, the Firm Shares, the Additional
      Shares and the Comcast Shares conform to the descriptions thereof
      contained in the Registration Statement and the Prospectus.

            (i) The Company does not own, directly or indirectly, any stock,
      partnership interest or joint venture interest in, or any security issued
      by, any other entity.

            (j) Each promissory note issued by the Company that was convertible
      into preferred stock of the Company has, prior to the date hereof, been
      converted into such preferred stock. All of the outstanding Series A,
      Series B and Series C Convertible Preferred Stock (collectively, the
      'Preferred Stock') of the Company has been duly and validly authorized and
      is validly issued and outstanding, fully paid and nonassessable and was
      not issued in violation of any preemptive rights and the shares of Common
      Stock issuable upon conversion thereof have been duly and validly
      authorized and reserved for issuance upon such conversion and, upon
      conversion of the Preferred Stock on the Closing Date, the shares of
      Common Stock issuable upon such conversion will be validly issued and
      outstanding, fully paid and nonassessable and will not have been issued in
      violation of or be subject to any preemptive rights. All outstanding
      warrants (the 'Warrants') to purchase Common Stock of the Company, have
      been duly and validly authorized, executed and delivered by the Company
      and constitute valid and binding obligations of the Company and the shares
      of Common Stock issuable upon exercise of such Warrants have been duly and
      validly authorized and reserved for issuance upon such exercise and, upon
      payment of the exercise price thereof upon exercise of such Warrants, such
      shares of Common Stock will be validly issued and outstanding, fully paid
      and nonassessable and will not have been issued in violation of or be
      subject to any preemptive rights. Except as described in or expressly
      contemplated by the Registration Statement and the Prospectus, there are
      no outstanding rights, warrants or options to acquire, or instruments
      convertible into or exchangeable for, any shares of capital stock or other
      equity interests in the Company or any of its subsidiaries, or any
      contract, commitment, agreement, understanding or arrangement (including
      without limitation preemptive rights) of any kind relating to the issuance
      of any capital stock of the Company or any such subsidiary, or any such
      convertible or exchangeable securities or any such rights, warrants or
      options.

            (k) The Company has been duly incorporated and is validly existing
      as a corporation in good standing under the laws of the state of Delaware.
      The Company is duly qualified and is in good standing as a foreign
      corporation in each jurisdiction in which the character or location of its
      properties (owned, leased or licensed) or the nature or conduct of its
      business makes such qualification necessary, except for those failures to


                                       4



      be so qualified or in good standing which will not, individually or in the
      aggregate, have a Material Adverse Effect. The Company has all requisite
      corporate power and authority, and all necessary consents, approvals,
      authorizations, orders, registrations, qualifications, licenses and
      permits of and from all public, regulatory or governmental agencies and
      bodies, to own, lease and operate its properties and conduct its business
      as now being conducted and as described in the Registration Statement and
      the Prospectus, except as would not result in a Material Adverse Effect,
      and no such consent, approval, authorization, order, registration,
      qualification, license or permit contains a materially burdensome
      restriction not adequately disclosed in the Registration Statement and the
      Prospectus.

            (l) Except as described in the Prospectus, there is no litigation or
      governmental proceeding to which the Company is a party or to which any
      property of the Company is subject or which is pending or, to the
      knowledge of the Company, contemplated against the Company which, if
      determined adversely to the Company, might individually or in the
      aggregate have a Material Adverse Effect, or which is required to be
      disclosed in the Registration Statement and the Prospectus, and there are
      no statutes, regulations, contracts or other documents that are required
      to be described in the Registration Statement or the Prospectus or to be
      filed as exhibits to the Registration Statement that are not described or
      filed as required.

            (m) The Company has not taken and will not take, directly or
      indirectly, any action designed to cause or result in, or which
      constitutes or which might reasonably be expected to constitute, the
      stabilization or manipulation of the price of the shares of Common Stock
      to facilitate the sale or resale of the Offered Shares.

            (n) The financial statements, including the notes thereto, and
      supporting schedules included in the Registration Statement and the
      Prospectus present fairly the financial position of the Company as of the
      dates indicated and the results of its operations and changes in cash
      flows for the periods specified; except as otherwise stated in the
      Registration Statement, said financial statements have been prepared in
      conformity with generally accepted accounting principles applied on a
      consistent basis; and the supporting schedules included in the
      Registration Statement present fairly the information required to be
      stated therein; and except as disclosed therein, the pro forma financial
      information included in the Registration Statement and the Prospectus has
      been prepared in accordance with the Commission's rules and guidelines
      with respect to pro forma financial statements and the assumptions used in
      the preparation thereof are, in the Company's opinion, reasonable; and the
      other financial and statistical information and data included in the
      Registration Statement and the Prospectus is, in all material respects,
      accurately presented and prepared on a basis consistent with such
      financial statements and the books and records of the Company.

            (o) Except as described in the Prospectus, no holder of securities
      of the Company has any rights to the registration of securities for sale
      under the Securities Act of 1933, as amended, of the Company because of
      the filing of the Registration Statement or otherwise in connection with
      the sale of the Offered Shares.


                                       5



            (p) The Company is not, and upon consummation of the transactions
      contemplated hereby and by the Comcast Purchase Agreement will not be,
      subject to registration as an 'investment company' under the Investment
      Company Act of 1940, as amended.

            (q) The Shares have been approved for quotation subject to official
      notice of issuance on the Nasdaq National Market System.

            (r) No labor dispute with the employees of the Company exists or, to
      the knowledge of the Company, is imminent.

            (s) Except as described in the Prospectus, the Company owns,
      possesses or can acquire on reasonable terms, adequate trademarks, trade
      names, inventions, know-how (including trade secrets and other unpatented
      and/or unpatentable proprietary or confidential information, systems or
      procedures), patents, copyrights, and other intellectual property
      reasonably necessary to conduct the business now operated by it, or
      presently employed by it, and has not received any notice of infringement
      of or conflict with asserted rights of others with respect to any
      intellectual property rights that, if determined adversely to the Company,
      would individually or in the aggregate have a Material Adverse Effect.

            (t) The Company (i) is in compliance with any and all applicable
      foreign, federal, state and local laws and regulations relating to (A) the
      protection of human health and safety and (B) the environment or hazardous
      or toxic substances or wastes, pollutants or contaminants ('Environmental
      Laws'), (ii) has received all permits, licenses or other approvals
      required of it under applicable Environmental Laws to conduct its business
      and (iii) is in compliance with all terms and conditions of any such
      permit, license or approval, except where such noncompliance with
      Environmental Laws, failure to receive required permits, licenses or other
      approvals or failure to comply with the terms and conditions of such
      permits, licenses or approvals would not, individually or in the
      aggregate, have a Material Adverse Effect.

            (u) There are no costs or liabilities associated with Environmental
      Laws (including, without limitation, any capital or operating expenditures
      required for clean-up, closure of properties or compliance with
      Environmental Laws or any permit, license or approval, any related
      constraints on operating activities and any potential liabilities to third
      parties) which would, individually or in the aggregate, have a Material
      Adverse Effect.

            (v) The Company owns no real property and has good and marketable
      title to all personal property owned by it which is material to the
      business of the Company, in each case free and clear of all liens,
      encumbrances and defects except such as are described in the Prospectus or
      such as do not materially affect the value of such property and do not
      materially interfere with the use made and proposed to be made of such
      property by the Company; and any real property and buildings held under
      lease by the Company are held by it under valid, subsisting and
      enforceable leases with such exceptions as are not material and do not
      materially interfere with the use made and proposed to be made of 


                                       6



      such property and buildings by the Company, in each case except as
      described in or contemplated by the Prospectus.

            (w) The Company is insured by insurers of recognized financial
      responsibility against such losses and risks and in such amounts as are
      prudent and customary in the business in which it is engaged; the Company
      has not been refused any insurance coverage sought or applied for; and the
      Company does not have any reason to believe that it will not be able to
      renew its existing insurance coverage as and when such coverage expires or
      to obtain similar coverage from similar insurers as may be necessary to
      continue its business at a cost that would not have a Material Adverse
      Effect.

            (x) The Company maintains a system of internal accounting controls
      sufficient to provide reasonable assurance that (i) transactions are
      executed in accordance with management's general or specific
      authorizations; (ii) transactions are recorded as necessary to permit
      preparation of financial statements in conformity with generally accepted
      accounting principles and to maintain asset accountability; (iii) access
      to assets is permitted only in accordance with management's general or
      specific authorization; and (iv) the recorded accountability for assets is
      compared with the existing assets at reasonable intervals and appropriate
      action is taken with respect to any differences. (y) Except as described
      in the Prospectus (exclusive of any amendments or supplements thereto
      subsequent to the date of this Agreement), the Company has not sold,
      issued or distributed any shares of Common Stock during the six-month
      period preceding the date hereof, including any sales of Common Stock
      pursuant to Rule 144A under, or Regulation D or S of, the Act, other than
      shares of Common Stock issued pursuant to employee benefit plans,
      qualified stock option plans or other employee compensation plans or
      pursuant to outstanding options, rights or warrants.

            (z) No relationship, direct or indirect, exists between or among the
      Company on the one hand, and the directors, officers, stockholders,
      customers, suppliers or providers of outsourced services of the Company on
      the other hand, which is required by the Act to be described in the
      Registration Statement and the Prospectus which is not so described.

            (aa) The merger of General Internet, Inc, a New York corporation
      ('General Internet'), with and into the Company (the 'Merger') has become
      effective and the identity, existence, corporate organization, purposes,
      powers, objects, franchises, privileges, rights, immunities, restrictions,
      debts, liabilities and duties (the 'Corporate Rights') of General Internet
      will continue in effect and be unimpaired by the Merger, and the Corporate
      Rights of General Internet have been merged with and into the Company,
      which is, as the surviving corporation, fully vested therewith. All
      consents, approvals, orders and authorizations of, and all registrations,
      declarations and filings with, all persons (governmental and private)
      required to be obtained or made in connection with the consummation of the
      Merger have been so obtained or made. The Merger qualifies as a
      reorganization under the provisions of Section 368 of the Internal Revenue
      Code of 1986, as amended.

      2. PURCHASE, SALE AND DELIVERY OF THE OFFERED SHARES.


                                       7

      the determination of the initial public offering price of the Offered
      Shares), such time and date of payment and delivery being herein called
      the 'Closing Date.' Payment shall be made to the Company by wire transfer

      HOWEVER, that no Additional Closing Date shall be earlier than the Closing
      Date or earlier than the second full business day after the date on which
      the option shall have been exercised nor later than the eighth full
      business day after the date on which the option shall have been exercised
      (unless such time and date are postponed in accordance with the provisions
      of Section 9 hereof). Certificates for Additional Shares shall be
      registered in such name or names and in such authorized denominations as
      the Representatives may request in writing at least two full business days
      prior to the applicable Additional Closing Date. The Company will permit
      you to examine and package such certificates for delivery at least one
      full business day prior to the applicable Additional Closing Date.


                                       8



      The number of Additional Shares to be sold to each Underwriter on an
Additional Closing Date shall be the number which bears the same ratio to the
aggregate number of Additional Shares being purchased on such Additional Closing
Date as the number of Firm Shares set forth opposite the name of such
Underwriter in Schedule I hereto (or such number increased as set forth in
Section 9 hereof) bears to 3,000,000 subject, however, to such adjustments to
eliminate any fractional shares as the Representatives in their sole discretion
shall make.

      Payment for the Additional Shares shall be made by wire transfer in same
day funds at the offices of Brobeck, Phleger & Harrison LLP, 1633 Broadway, 47th
Floor, New York, New York 10019, or such other location as may be mutually
acceptable, upon delivery of the certificates for the Additional Shares to the
Representatives for the respective accounts of the Underwriters.

      3. OFFERING.

            (a) Upon the Representatives' authorization of the release of the
      Firm Shares, the Underwriters propose to offer the Offered Shares for sale
      to the public upon the terms set forth in the Prospectus.

            (b) The Company and the Underwriters hereby agree that up to 300,000
      of the Firm Shares to be purchased by the Underwriters (the 'Directed
      Shares') shall be reserved for sale by the Underwriters to eligible
      employees of and certain persons designated by the Company (the 'Directed
      Shares Purchasers'), as part of the distribution of the Offered Shares by
      the Underwriters subject to the terms of this Agreement, the applicable
      rules, regulations and interpretations of the National Association of
      Securities Dealers, Inc. and all other applicable laws, rules and
      regulations, PROVIDED, HOWEVER, that under no circumstances will Bear,
      Stearns & Co. Inc. or any other Underwriter be liable to the Company or to
      any of the -------- ------- Directed Shares Purchasers for any action
      taken or omitted in good faith in connection with transactions effected
      with regard to the Directed Shares Purchasers. To the extent that such
      Directed Shares are not orally confirmed for purchase by such persons by
      the end of the first day after the date of this Agreement, such Directed
      Shares will be offered to the public as part of the underwritten offering
      contemplated hereby.

      4. COVENANTS OF THE COMPANY. The Company covenants and agrees with the
Underwriters that:

            (a) If the Registration Statement has not yet been declared
      effective, the Company will use its best efforts to cause the Registration
      Statement and any amendments thereto to become effective as promptly as
      possible, and if Rule 430A is used or the filing of the Prospectus is
      otherwise required under Rule 424(b) or Rule 434, the Company will file
      the Prospectus (properly completed if Rule 430A has been used) pursuant to
      Rule 424(b) or Rule 434 within the prescribed time period and will provide
      evidence satisfactory to the Representatives of such timely filing. If the
      Company elects to rely on Rule 434, the Company will prepare and file a
      term sheet that complies with the requirements of Rule 434.


                                       9



      The Company will notify the Representatives as promptly as possible (and,
if requested by you will confirm such notice in writing) (i) when the
Registration Statement and any amendments thereto become effective, (ii) of any
request by the Commission for any amendment of or supplement to the Registration
Statement or the Prospectus or for any additional information, (iii) of the
mailing or the delivery to the Commission for filing of any amendment of or
supplement to the Registration Statement or the Prospectus, (iv) of the issuance
by the Commission of any stop order suspending the effectiveness of the
Registration Statement or any post-effective amendment thereto or of the
initiation, or the threatening, of any proceedings therefor, (v) of the receipt
of any comments from the Commission, and (vi) of the receipt by the Company of
any notification with respect to the suspension of the qualification of the
Shares for sale in any jurisdiction or the initiation or threatening of any
proceeding for that purpose. If the Commission shall propose or enter a stop
order at any time, the Company will make every reasonable effort to prevent the
issuance of any such stop order and, if issued, to obtain the lifting of such
order as soon as possible. The Company will not file any amendment to the
Registration Statement or any amendment of or supplement to the Prospectus
(including the prospectus required to be filed to Rule 424(b) or Rule 434) that
differs from the prospectus on file at the time of the effectiveness of the
Registration Statement before or after the effective date of the Registration
Statement to which the Representatives shall reasonably object in writing after
being timely furnished in advance a copy thereof.

            (b) If at any time when a prospectus relating to the Offered Shares
      is required to be delivered under the Act any event shall have occurred as
      a result of which the Prospectus as then amended or supplemented would, in
      the judgment of the Underwriters or the Company, include an untrue
      statement of a material fact or omit to state any material fact required
      to be stated in order to make any statement therein, in light of the
      circumstances under which it was made, not misleading, or if it shall be
      necessary, in the judgment of the Underwriters or the Company, at any time
      to amend or supplement the Prospectus or the Registration Statement to
      comply with the Act or the Regulations, the Company will notify the
      Representatives promptly and prepare and file with the Commission an
      appropriate amendment or supplement (in form and substance satisfactory to
      the Representatives) which will correct such statement or omission and
      will use its best efforts to have any amendment to the Registration
      Statement declared effective as soon as possible.

            (c) The Company will promptly deliver to the Representatives two
      signed copies of the Registration Statement, including exhibits and all
      amendments thereto, and the Company will promptly deliver to each of the
      Underwriters such number of copies of any preliminary prospectus, the
      Prospectus, the Registration Statement and all amendments of and
      supplements to such documents, if any, as the Representatives may
      reasonably request.

            (d) The Company will endeavor in good faith, in cooperation with the
      Representatives, at or prior to the time of effectiveness of the
      Registration Statement, to qualify the Offered Shares for offering and
      sale under the securities laws relating to the offering or sale of the
      Shares of such jurisdictions as the Representatives may designate 


                                       10



      and to maintain such qualification in effect for so long as required for
      the distribution thereof, except that in no event shall the Company be
      obligated in connection therewith to qualify as a foreign corporation or
      to execute a general consent to service of process.

            (e) The Company will make generally available (within the meaning of
      11(a) of the Act) to its security holders and to the Representatives as
      soon as practicable, but not later than 45 days after the end of its
      fiscal quarter in which the first anniversary date of the effective date
      of the Registration Statement occurs, an earnings statement (in form
      complying with the provisions of Rule 158 of the Regulations) covering a
      period of at least twelve consecutive months beginning after the effective
      date of the Registration Statement.

            (f) During the period of 180 days from the date of the Prospectus,
      the Company will not, without the prior written consent of Bear, Stearns & Co. Inc., issue, sell, offer or agree to sell, grant any option for the
      sale of, pledge, make any short sale, establish an open 'put equivalent
      position' within the meaning of Rule 16a-1(h) under the Securities
      Exchange Act of 1934, as amended, or otherwise dispose of, any Common
      Stock (or any securities convertible into, exercisable for or exchangeable
      for Common Stock) of the Company or (ii) enter into any swap, derivative
      transaction or other arrangement that transfers to another, in whole or in
      part, any of the economic consequences of ownership of the Common Stock,
      whether any such transaction described in clause (i) or (ii) above is to
      be settled by delivery of Common Stock or such other securities, in cash
      or otherwise, PROVIDED that the foregoing shall not apply to (A) the
      Shares, (B) the issuance of Common Stock upon conversion of the Preferred
      Stock on the -------- Closing Date, (C) the issuance by the Company of
      shares of Common Stock upon the exercise of any warrant outstanding on the
      date hereof and disclosed in the Prospectus, (D) the issuance by the
      Company of shares of Common Stock or options to purchase Common Stock
      pursuant to any stock option or incentive plan described in the Prospectus
      and (E) the issuance by the Company of shares of Common Stock in
      connection with any acquisition of another company if the terms of such
      issuance provide that such shares shall not be resold prior to the
      expiration of the 180-day period from the date of the Prospectus; and the
      Company will obtain the undertaking of each of its officers and directors
      and such of its stockholders as have been heretofore designated by the
      Representatives and listed on Schedule II attached hereto not to engage in
      any of the aforementioned transactions on their own behalf.

            (g) During a period of three years from the effective date of the
      Registration Statement, the Company will furnish to the Representatives,
      copies of (i) all reports to its stockholders; and (ii) all reports,
      financial statements and proxy or information statements filed by the
      Company with the Commission or any national securities exchange.

            (h) The Company will apply the proceeds from the sale of the Shares
      as set forth under 'Use of Proceeds' in the Prospectus.

            (i) The Company will use its best efforts to cause the Shares to
      continue to qualify for inclusion in the Nasdaq National Market System.


                                       11


            (j) The Company will use its best efforts to ensure that the
      Directed Shares are restricted as required by the National Association of
      Securities Dealers Inc. or the National Association of Securities Dealers
      Inc. rules from sale, transfer, assignment, pledge or hypothecation for a
      period of three (3) months following the date of this Agreement. The
      Underwriters will notify the Company as to which persons will need to be
      so restricted. At the request of the Underwriters, the Company will direct
      the transfer agent to place a stop transfer restriction upon such
      securities for such a period of time. Should the Company release, or seek
      to release, from such restrictions any of the Directed Shares, the Company
      agrees to reimburse the Underwriters for any reasonable expenses
      (including, without limitation, legal expenses) they incur in connection
      with such release.

      5. PAYMENT OF EXPENSES. Whether or not the transactions contemplated in
this Agreement are consummated or this Agreement is terminated, the Company
hereby agrees to pay all costs and expenses incident to the performance of the
obligations of the Company hereunder and under the Comcast Purchase Agreement,

Shares on the Nasdaq National Market System, (vi) filing fees of the Commission
and the National Association of Securities Dealers, Inc., (vii) the cost of

      6. CONDITIONS OF UNDERWRITERS' OBLIGATIONS. The obligations of the
Underwriters to purchase and pay for the Firm Shares and the Additional Shares,
as provided herein, shall be subject to the accuracy of the representations and
warranties of the Company herein contained, as of the date hereof and as of the
Closing Date (for purposes of this Section 6, 'Closing Date' shall refer to the
Closing Date for the Firm Shares and any Additional Closing Date, if different,
for the Additional Shares), to the absence from any certificates, opinions,
written statements or letters furnished to you or to O'Sullivan Graev & Karabell, LLP ('Underwriters' Counsel') pursuant to this Section 6 of any
misstatement or omission, to the performance by the Company of its obligations
hereunder, and to the following additional conditions:


                                       12



            (a) The Registration Statement shall have become effective not later
      than, if pricing pursuant to Rule 430A, 5:30 P.M., New York time, on the
      date of this Agreement or, if pricing pursuant to a pricing amendment,
      12:00 P.M., New York time on the date an amendment to the Registration
      Statement containing the public offering price has been filed with the
      Commission, or at such later time and date as shall have been consented to
      in writing by the Representatives; if the Company shall have elected to
      rely upon Rule 430A or Rule 434 of the Regulations, the Prospectus shall
      have been filed with the Commission in a timely fashion in accordance with
      Section 4(a) hereof; and, at or prior to the Closing Date, no stop order
      suspending the effectiveness of the Registration Statement or any
      post-effective amendment thereof shall have been issued and no proceedings
      therefor shall have been initiated or threatened by the Commission.

            (b) At the Closing Date, you shall have received the opinion of
      Brobeck, Phleger & Harrison LLP, counsel for the Company, dated the
      Closing Date addressed to the Underwriters and in form and substance
      satisfactory to Underwriters' Counsel, to the effect that:

                  (i) The Company has been duly incorporated and is validly
            existing in good standing under the laws of the State of Delaware.
            The Company is duly qualified to transact business and is in good
            standing as a foreign corporation in New York. The Company has the
            requisite corporate power and authority, to own, lease and operate
            its properties and conduct its business as described in the
            Registration Statement and the Prospectus.

                  (ii) The authorized capital stock of the Company is as set
            forth in the Registration Statement and the Prospectus. All of the
            outstanding shares of Common Stock (including the shares of Common
            Stock issued on the Closing Date upon conversion of the Preferred
            Stock) are duly authorized and validly issued, are fully paid and
            nonassessable and were not issued in violation of any preemptive
            rights arising under the Delaware General Corporation Law or, to
            such counsel's knowledge, similar rights that entitle or will
            entitle any person to acquire any shares of capital stock of the
            Company upon the issuance and sale of the Shares by the Company. The
            Shares to be sold by the Company on the Closing Date have been duly
            authorized and, when issued and delivered to the Underwriters or
            Comcast, as applicable, against payment therefor in accordance with
            this Agreement or the Comcast Purchase Agreement, as applicable,
            will be validly issued, fully paid and nonassessable and will not
            have been issued in violation of any preemeptive rights arising
            under the Delaware General Corporation Law or, to such counsel's
            knowledge, similar rights that entitle or will entitle any person to
            acquire any shares of capital stock of the Company upon the issuance
            and sale of the Shares by the Company. The Common Stock, the Firm
            Shares, the Additional Shares and the Comcast Shares conform as to
            legal matters to the descriptions thereof contained in the
            Registration Statement and the Prospectus.

                  (iii) All outstanding Warrants to purchase Common Stock of the
            Company have been duly authorized, executed and delivered by the
            Company and constitute 


                                       13



            valid and binding obligations of the Company, enforceable against it
            in accordance with their terms, subject to applicable bankruptcy,
            insolvency, reorganization, moratorium or other similar laws
            relating to or affecting creditors' rights and remedies generally,
            and subject, as to enforceability, to general equitable principles
            (whether relief is sought in a proceeding at law or in equity) and
            except as rights to indemnification and contribution thereunder may
            be limited by applicable law or public policy relating thereto. The
            shares of Common Stock issuable upon exercise of such Warrants have
            been duly reserved for issuance upon such exercise and, upon payment
            of the exercise price thereof upon exercise of such Warrants, such
            shares of Common Stock will be validly issued and outstanding, fully
            paid and nonassessable and will be free of any preemptive rights
            arising under the Delaware General Corporation Law or, to such
            counsel's knowledge, similar rights that entitle or will entitle any
            person to acquire any shares of capital stock of the Company upon
            the issuance and sale of such shares of Common Stock by the Company.

                  (iv) This Agreement and the Comcast Purchase Agreement have
            been duly and validly authorized, executed and delivered by the
            Company.

                  (v) To such counsel's knowledge, (i) there is no litigation or
            governmental or other action, suit, proceeding or investigation
            before any court or before or by any public, regulatory or
            governmental agency or body pending or, threatened against, or
            involving the properties or business of, the Company, which is of a
            character required to be disclosed in the Registration Statement and
            the Prospectus which has not been properly disclosed therein and
            (ii) there are no statutes, regulations, contracts or other
            documents that are required to be described in the Registration
            Statement or the Prospectus or to be filed as exhibits to the
            Registration Statement that are not described or filed as required.

                  (vi) The execution, delivery and performance of this Agreement
            and the Comcast Purchase Agreement and the consummation of the
            transactions contemplated hereby and thereby by the Company do not
            and will not (A) conflict with or result in a breach of any of the
            terms and provisions of, or constitute a default (or an event which
            with notice or lapse of time, or both, would constitute a default)
            under, or result in the creation or imposition of any lien, charge
            or encumbrance upon any properties or assets of the Company pursuant
            to, any agreement, instrument, franchise, license or permit known to
            such counsel to which the Company is a party or by which any of its
            properties or assets may be bound or (B) violate or conflict with
            any provision of applicable law or the certificate of incorporation
            or by-laws (or other organizational documents) of the Company, or
            any statute, rule or regulation, or to the best knowledge of such
            counsel, any judgment, decree or order, of any court or any public,
            governmental or regulatory agency or body having jurisdiction over
            the Company or any of its properties or assets. No consent,
            approval, authorization, order, registration, filing, qualification,
            license or permit of or with any court or any public, governmental
            or regulatory agency or body having jurisdiction over the Company or
            any of its properties or assets is required for the execution,
            delivery and 


                                       14



            performance of this Agreement or the Comcast Purchase Agreement or
            the consummation of the transactions contemplated hereby or thereby,
            except for (1) such as may be required under state securities or
            Blue Sky laws in connection with the purchase and distribution of
            the Offered Shares by the Underwriters (as to which such counsel
            need express no opinion) and (2) such as have been made or obtained
            under the Act. The issuance and sale of the Comcast Shares pursuant
            to the Comcast Purchase Agreement is exempt from the registration
            requirements of the Act by virtue of Section 4(2) of the Act.

                  (vii) The statements (A) in the Prospectus under the captions
            'Business-- Government Regulation and Legal Uncertainties,'
            'Management -- Employment, Severance and Other Agreements,' '--1998
            Stock Option/Stock Issuance Plan,' 'Description of Securities' and
            'Shares Eligible for Future Sale' and (B) in the Registration
            Statement in Items 14 and 15, in each case insofar as such
            statements constitute summaries of the legal matters, documents or
            proceedings referred to therein, provide a fair summary of such
            legal matters, documents and proceedings in all material respects.

                  (viii) The Company is not, and upon consummation of the
            transactions contemplated hereby and by the Comcast Purchase
            Agreement, will not be, an 'investment company' as such term is
            defined in the Investment Company Act of 1940, as amended.

                  (ix) The Registration Statement and the Prospectus and any
            amendments thereof or supplements thereto (except for the financial
            statements and the schedules and the other financial and statistical
            data included in the Registration Statement and the Prospectus, as
            to which no opinion need be rendered) comply as to form in all
            material respects with the requirements of the Act and the
            Regulations.

                  (x) The Registration Statement has been declared effective
            under the Act, and, to the knowledge of such counsel, no stop order
            suspending the effectiveness of the Registration Statement or any
            post-effective amendment thereof has been issued and no proceedings
            therefor have been initiated or threatened by the Commission and any
            required filing of the Prospectus pursuant to Rule 424(b) of the
            Regulations has been made in accordance with Rule 424(b).

                  (xi) To such counsel's knowledge, except as described in the
            Prospectus, no holder of any security of the Company has the right,
            not effectively satisfied or waived, to require inclusion of shares
            of Common Stock or any other security of the Company in the
            Registration Statement.

                  (xii) The Merger has become effective and the Corporate Rights
            of General Internet will continue in effect and be unimpaired by the
            Merger, and the Corporate Rights of General Internet have been
            merged with and into the Company, which is, as the surviving
            corporation, fully vested therewith. All consents, approvals, orders
            and authorizations of, and all registrations, 


                                       15



            declarations and filings with, all persons (governmental and, to
            such counsel's knowledge, private) required to be obtained or made
            in connection with the consummation of the Merger have been so
            obtained or made. The Merger qualifies as a reorganization under the
            provisions of Section 368 of Internal Revenue Code.

      In addition, such opinion shall also contain a statement that such counsel
has participated in conferences with certain officers and representatives of the
Company, its independent public accountants, the Underwriters and the
Underwriters' counsel at which the contents of the Registration Statement and
the Prospectus and related matters were discussed. Such counsel need not,
however, pass upon, or assume any responsibility for, and such counsel may state
that it has not independently checked or verified, the accuracy, completeness or
fairness of the information contained in the Registration Statement and the
Prospectus. Such counsel shall state, however, that based upon its participation
as described in the preceding two sentences, (i) it confirms that it has no
reason to believe that the Registration Statement (other than the financial
statements, including the notes and schedules thereto, and the other financial
and statistical data included in the Registration Statement, as to which such
counsel need not express any belief), at the time the Registration Statement
became effective, contained any untrue statement of a material fact or omitted
to state a material fact required to be stated therein or necessary to make the
statements therein not misleading; and (ii) it confirms that it has no reason to
believe that the Prospectus (other than the financial statements, including the
notes and schedules thereto, and the other financial and statistical data
included in the Prospectus, as to which such counsel need not express any
belief), on the date of such opinion, contains any untrue statement of a
material fact or omits to state a material fact necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading.

      In rendering such opinion, such counsel may rely (A) as to matters
involving the application of laws other than the laws of the United States, the
General Corporation Law of the State of Delaware, the laws of the State of New
York, to the extent such counsel deems proper and to the extent specified in
such opinion, if at all, upon an opinion or opinions (in form and substance
reasonably satisfactory to Underwriters' Counsel) of other counsel reasonably
acceptable to Underwriters' Counsel, familiar with the applicable laws; (B) as
to matters of fact, to the extent they deem proper, on certificates of
responsible officers of the Company and certificates or other written statements
of officers of departments of various jurisdictions having custody of documents
respecting the corporate existence or good standing of the Company, provided
that copies of any such statements or certificates shall be delivered to
Underwriters' Counsel. The opinion of such counsel for the Company shall state
that the opinion of any such other counsel is in form satisfactory to such
counsel and, in their opinion, you and they are justified in relying thereon.

      The opinion of Brobeck, Phleger & Harrison LLP described in this Section
6(b) shall be rendered to the Underwriters at the request of the Company and
shall so state therein.

            (c) All proceedings taken in connection with the sale of the Shares
      as herein contemplated and as contemplated in the Comcast Purchase
      Agreement shall be satisfactory in form and substance to you and to
      Underwriters' Counsel, and the Underwriters shall have received from said
      Underwriters' Counsel a favorable opinion, 


                                       16



      dated as of the Closing Date with respect to the issuance and sale of the
      Offered Shares, the Registration Statement and the Prospectus and such
      other related matters as the Representatives may reasonably require, and
      the Company shall have furnished to Underwriters' Counsel such documents
      as they request for the purpose of enabling them to pass upon such
      matters.

            (d) At the Closing Date, you shall have received a certificate of
      the Chief Executive Officer and Chief Financial Officer of the Company,
      dated the Closing Date to the effect that (i) the condition set forth in
      subsection (a) of this Section 6 has been satisfied, (ii) as of the date
      hereof and as of the Closing Date, the representations and warranties of
      the Company set forth in Section 1 hereof are accurate, (iii)
      simultaneously with the Closing, the sale of the Comcast Shares pursuant
      to the Comcast Purchase Agreement shall have been consummated and the
      Company shall have received $2,500,000 as a result of such sale, (iv) as
      of the Closing Date, the obligations of the Company to be performed
      hereunder and under the Comcast Purchase Agreement on or prior thereto
      have been duly performed and (v) subsequent to the respective dates as of
      which information is given with the Registration Statement and the
      Prospectus, the Company has not sustained any material loss or
      interference with its business or properties from fire, flood, hurricane,
      accident or other calamity, whether or not covered by insurance, or from
      any labor dispute or any legal or governmental proceeding, and there has
      not been any material adverse change, or any development involving a
      material adverse change, in the business, prospects, properties,
      operations, condition (financial or otherwise), or results of operations
      of the Company, except in each case as described in or contemplated by the
      Prospectus.

            (e) At the time this Agreement is executed and at the Closing Date,
      you shall have received a letter from KPMG LLP, independent public
      accountants for the Company, dated, respectively, as of the date of this
      Agreement and as of the Closing Date addressed to the Underwriters and in
      form and substance satisfactory to the Representatives, to the effect
      that: (i) they are independent certified public accountants with respect
      to the Company within the meaning of the Act and the Regulations and
      stating that the answer to Item 10 of the Registration Statement is
      correct insofar as it relates to them; (ii) stating that, in their
      opinion, the financial statements and schedules of the Company included in
      the Registration Statement and the Prospectus and covered by their opinion
      therein comply as to form in all material respects with the applicable
      accounting requirements of the Act and the applicable published rules and
      regulations of the Commission thereunder; (iii) on the basis of procedures
      consisting of a reading of the latest available unaudited interim
      consolidated financial statements of the Company, a reading of the minutes
      of meetings and consents of the stockholders and board of directors of the
      Company and the committees of such board subsequent to December 31, 1998,
      inquiries of officers and other employees of the Company who have
      responsibility for financial and accounting matters of the Company and its
      subsidiaries with respect to transactions and events subsequent to
      December 31, 1998 and other specified procedures and inquiries to a date
      not more than five days (three days in the case of the letter delivered on
      the Closing Date) prior to the date of such letter, nothing has come to
      their attention that would cause them to believe that: (A) the unaudited
      consolidated financial statements and schedules of the Company presented
      in the Registration Statement and the 


                                       17



      Prospectus do not comply as to form in all material respects with the
      applicable accounting requirements of the Act and the applicable published
      rules and regulations of the Commission thereunder or that such unaudited
      consolidated financial statements are not fairly presented in conformity
      with generally accepted accounting principles applied on a basis
      substantially consistent with that of the audited consolidated financial
      statements of the Company included in the Registration Statement and the
      Prospectus; (B) with respect to the period subsequent to December 31, 1998
      there were, as of the date of the most recent available monthly financial
      statements of the Company and as of a specified date not more than five
      days (three days in the case of the letter delivered on the Closing Date)
      prior to the date of such letter, any changes in the capital stock or
      long-term indebtedness of the Company or any decrease in the net current
      assets or stockholders' equity of the Company, in each case, as compared
      with the amounts shown in the most recent balance sheet presented in the
      Registration Statement and the Prospectus, except for changes or decreases
      which the Registration Statement and the Prospectus disclose have occurred
      or may occur or which are set forth in such letter or (C) that during the
      period from January 1, 1999 to the date of the most recent available
      monthly financial statements of the Company and to a specified date not
      more than five days (three days in the case of the letter delivered on the
      Closing Date) prior to the date of such letter, there was (1) any
      decrease, as compared with the corresponding period in the prior fiscal
      year, in total revenues, or any increase, as compared with the
      corresponding period in the prior fiscal year, in operating loss or the
      total or per share net loss or (2) any decrease, as compared with the
      corresponding period in the prior fiscal quarter, in revenues, except in
      any such case for decreases or increases which the Registration Statement
      and the Prospectus disclose have occurred or may occur or which are set
      forth in such letter; (iv) nothing has come to their attention that would
      cause them to believe that the pro forma financial information included in
      the Registration Statement do not comply in all material respects with the
      applicable accounting requirements of Rule 11-02 of Regulation S-X or that
      the pro forma adjustments have not been properly applied to the historical
      amounts in the compilation of such financial information; and (v) stating
      that they have compared specific dollar amounts, numbers of shares,
      percentages of revenues and earnings, and other financial information
      pertaining to the Company set forth in the Registration Statement and the
      Prospectus, which have been specified by the Representatives prior to the
      date of this Agreement, to the extent that such amounts, numbers,
      percentages and information may be derived from the general accounting and
      financial records of the Company or from schedules furnished by the
      Company, and excluding any questions requiring an interpretation by legal
      counsel, with the results obtained from the application of specified
      readings, inquiries and other appropriate procedures specified by the
      Representatives set forth in such letter, and found them to be in
      agreement.

            (f) Prior to the Closing Date, the Company shall have furnished to
      you such further information, certificates and documents as you may
      reasonably request.

            (g) The Representatives shall have received from each person who is
      a director or officer of the Company or stockholder that has been
      heretofore designated by the Representatives and listed on Schedule II
      hereto an agreement to the effect that such person will not, directly or
      indirectly, without the prior written consent of Bear, Stearns 


                                       18



      & Co. Inc., offer, sell, offer or agree to sell, grant any option to
      purchase, pledge, make any short sale, establish an open 'put equivalent
      position' within the meaning of Rule 16a-1(h) under the Securities
      Exchange Act of 1934, as amended, or otherwise dispose of, any Common
      Stock (or any securities convertible into, exercisable for or exchangeable
      for Common Stock) of the Company or (ii) enter into any swap, derivative
      transaction or other arrangement that transfers to another, in whole or in
      part, any of the economic consequences of ownership of the Common Stock,
      whether any such transaction described in clause (i) or (ii) above is to
      be settled by delivery of Common Stock or such other securities, in cash
      or otherwise, for a period of 180 days after the date of the Prospectus.

            (h) The closing of the sale of the Comcast Shares shall be
      consummated concurrently with or prior to the closing of the sale of the
      Firm Shares and the Company shall have received $____ per share or
      [$2,500,000] in the aggregate with respect thereto.

            (i) At the Closing Date, the Shares shall have been approved for
      quotation on the Nasdaq National Market System.

      If any of the conditions specified in this Section 6 shall not have been
fulfilled when and as required by this Agreement, or if any of the certificates,
opinions, written statements or letters furnished to you or to Underwriters'
Counsel pursuant to this Section 6 shall not be in all material respects
reasonably satisfactory in form and substance to the Representatives and to
Underwriters Counsel, all obligations of the Underwriters hereunder may be
cancelled by the Representatives at, or at any time prior to, the Closing Date
and the obligations of the Underwriters to purchase the Additional Shares may be
cancelled by the Representatives at, or at any time prior to, the Additional
Closing Date. Notice of such cancellation shall be given to the Company in
writing, or by telephone, telex or telegraph, confirmed in writing.

      7. INDEMNIFICATION.

            (a) The Company agrees to indemnify and hold harmless each
      Underwriter and each person, if any, who controls any Underwriter within
      the meaning of Section 15 of the Act or Section 20(a) of the Securities
      Exchange Act of 1934, as amended (the 'Exchange Act'), against any and all
      losses, liabilities, claims, damages and expenses whatsoever as incurred
      (including but not limited to attorneys' fees and any and all expenses
      whatsoever incurred in investigating, preparing or defending against any
      litigation, commenced or threatened, or any claim whatsoever, and any and
      all amounts paid in settlement of any claim or litigation), joint or
      several, to which they or any of them may become subject under the Act,
      the Exchange Act or otherwise, insofar as such losses, liabilities,
      claims, damages or expenses (or actions in respect thereof) arise out of
      or are based upon any untrue statement or alleged untrue statement of a
      material fact contained in the registration statement for the registration
      of the Offered Shares, as originally filed or any amendment thereof, or
      any related preliminary prospectus or the Prospectus, or in any supplement
      thereto or amendment thereof, or arise out of or are based upon the
      omission or alleged omission to state therein a material fact required to
      be stated therein or necessary to make the statements therein not
      misleading; PROVIDED, HOWEVER, that the Company will not be liable in any
      such case to the extent but only to 


                                       19



      the extent that any such loss, liability, claim, damage or expense arises
      out of or is based upon any such untrue statement or alleged untrue
      statement or omission or alleged omission made therein in reliance upon
      and in conformity with written information furnished to the Company by or
      on behalf of any Underwriter through the Representatives expressly for use
      therein. This indemnity agreement will be in addition to any liability
      which the Company may otherwise have, including under this Agreement.

            (b) Each Underwriter severally, and not jointly, agrees to indemnify
      and hold harmless the Company, each of the directors of the Company, each
      of the officers of the Company who shall have signed the Registration
      Statement, and each other person, if any, who controls the Company within
      the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act,
      against any losses, liabilities, claims, damages and expenses whatsoever
      as incurred (including but not limited to attorneys' fees and any and all
      expenses whatsoever incurred in investigating, preparing or defending
      against any litigation, commenced or threatened, or any claim whatsoever,
      and any and all amounts paid in settlement of any claim or litigation),
      jointly or severally, to which they or any of them may become subject
      under the Act, the Exchange Act or otherwise, insofar as such losses,
      liabilities, claims, damages or expenses (or actions in respect thereof)
      arise out of or are based upon any untrue statement or alleged untrue
      statement of a material fact contained in the registration statement for
      the registration of the Shares, as originally filed or any amendment
      thereof, or any related preliminary prospectus or the Prospectus, or in
      any amendment thereof or supplement thereto, or arise out of or are based
      upon the omission or alleged omission to state therein a material fact
      required to be stated therein or necessary to make the statements therein
      not misleading, in each case to the extent, but only to the extent, that
      any such loss, liability, claim, damage or expense arises out of or is
      based upon any such untrue statement or alleged untrue statement or
      omission or alleged omission made therein in reliance upon and in
      conformity with written information furnished to the Company by or on
      behalf of any Underwriter through the Representatives expressly for use
      therein; PROVIDED, HOWEVER, that in no case shall any Underwriter be
      liable or responsible for any amount in excess of the underwriting
      discount applicable to the Shares purchased by such Underwriter hereunder.
      This indemnity will be in addition to any liability which any Underwriter
      may otherwise have, including under this Agreement. The Company
      acknowledges that the statements set forth in the third, seventh and
      twelfth paragraphs under the caption 'Underwriting' in the Prospectus
      constitute the only information furnished in writing by or on behalf of
      any Underwriter expressly for use in the registration statement relating
      to the Offered Shares as originally filed or in any amendment thereof, any
      related preliminary prospectus or the Prospectus or in any amendment
      thereof or supplement thereto, as the case may be.

            (c) In connection with the offer and sale of the Directed Shares,
      the Company agrees, promptly upon a request in writing, to indemnify and
      hold harmless the Underwriters from and against any and all losses,
      liabilities, claims, damages and expenses incurred by them as a result of
      the failure of the Directed Shares Purchasers to pay for and accept
      delivery of the Directed Shares which, by the end of the day following the
      date of this Agreement, were subject to a properly confirmed agreement to
      purchase such Directed Shares.


                                       20



            (d) Promptly after receipt by an indemnified party under subsection
      (a) or (b) above of notice of the commencement of any action, such
      indemnified party shall, if a claim in respect thereof is to be made
      against the indemnifying party under such subsection, notify each party
      against whom indemnification is to be sought in writing of the
      commencement thereof (but the failure so to notify an indemnifying party
      shall not relieve it from any liability which it may have under this
      Section 7). In case any such action is brought against any indemnified
      party, and it notifies an indemnifying party of the commencement thereof,
      the indemnifying party will be entitled to participate therein, and to the
      extent it may elect by written notice delivered to the indemnified party
      promptly after receiving the aforesaid notice from such indemnified party,
      to assume the defense thereof with counsel satisfactory to such
      indemnified party. Notwithstanding the foregoing, the indemnified party or
      parties shall have the right to employ its or their own counsel in any
      such case, but the fees and expenses of such counsel shall be at the
      expense of such indemnified party or parties unless (i) the employment of
      such counsel shall have been authorized in writing by one of the
      indemnifying parties in connection with the defense of such action, (ii)
      the indemnifying parties shall not have employed counsel to have charge of
      the defense of such action within a reasonable time after notice of
      commencement of the action, or (iii) such indemnified party or parties
      shall have reasonably concluded that there may be defenses available to it
      or them which are different from or additional to those available to one
      or all of the indemnifying parties (in which case the indemnifying parties
      shall not have the right to direct the defense of such action on behalf of
      the indemnified party or parties), in any of which events such fees and
      expenses shall be borne by the indemnifying parties. Anything in this
      subsection to the contrary notwithstanding, an indemnifying party shall
      not be liable for any settlement of any claim or action effected without
      its written consent; PROVIDED, HOWEVER, that -------- ------- such consent
      was not unreasonably withheld.

      8. CONTRIBUTION. In order to provide for contribution in circumstances in
which the indemnification provided for in Section 7 hereof is for any reason
held to be unavailable from any indemnifying party or is insufficient to hold
harmless a party indemnified thereunder, the Company, and the Underwriters shall
contribute to the aggregate losses, claims, damages, liabilities and expenses of
the nature contemplated by such indemnification provision (including any
investigation, legal and other expenses incurred in connection with, and any
amount paid in settlement of, any action, suit or proceeding or any claims
asserted, but after deducting in the case of losses, claims, damages,
liabilities and expenses suffered by the Company any contribution received by
the Company from persons, other than the Underwriters, who may also be liable
for contribution, including persons who control the Company within the meaning
of Section 15 of the Act or Section 20(a) of the Exchange Act, officers of the
Company who signed the Registration Statement and directors of the Company) as
incurred to which the Company, and one or more of the Underwriters may be
subject, in such proportions as is appropriate to reflect the relative benefits
received by the Company and the Underwriters from the offering of the Offered
Shares or, if such allocation is not permitted by applicable law or
indemnification is not available as a result of the indemnifying party not
having received notice as provided in Section 7 hereof, in such proportion as is
appropriate to reflect not only the relative benefits referred to above but also
the relative fault of the Company and the Underwriters in connection with the
statements or omissions which resulted in such losses, claims, damages,
liabilities or expenses, as well as any other relevant equitable considerations.
The relative benefits received 


                                       21



by the Company and the Underwriters shall be deemed to be in the same proportion
as (x) the total proceeds from the offering of the Offered Shares (net of
underwriting discounts and commissions but before deducting expenses) received
by the Company and (y) the underwriting discounts and commissions received by
the Underwriters, respectively, in each case as set forth in the table on the
cover page of the Prospectus. The relative fault of the Company and of the
Underwriters shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of a material fact or the omission or
alleged omission to state a material fact relates to information supplied by the
Company or the Underwriters and the parties' relative intent, knowledge, access
to information and opportunity to correct or prevent such statement or omission.
The Company and the Underwriters agree that it would not be just and equitable
if contribution pursuant to this Section 8 were determined by pro rata
allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation which does not take account of the
equitable considerations referred to above. Notwithstanding the provisions of
this Section 8, (i) in no case shall any Underwriter be liable or responsible
for any amount in excess of the underwriting discount applicable to the Shares
purchased by such Underwriter hereunder, and (ii) no person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation. Notwithstanding the provisions of this Section 8 and the
preceding sentence, no Underwriter shall be required to contribute any amount in
excess of the amount by which the total price at which the Offered Shares
underwritten by it and distributed to the public were offered to the public
exceeds the amount of any damages that such Underwriter has otherwise been
required to pay by reason of such untrue or alleged untrue statement or omission
or alleged omission. For purposes of this Section 8, each person, if any, who
controls an Underwriter within the meaning of Section 15 of the Act or Section
20(a) of the Exchange Act shall have the same rights to contribution as such
Underwriter, and each person, if any, who controls the Company within the
meaning of Section 15 of the Act or Section 20(a) of the Exchange Act, each
officer of the Company who shall have signed the Registration Statement and each
director of the Company shall have the same rights to contribution as the
Company, subject in each case to clauses (i) and (ii) of this Section 8. Any
party entitled to contribution will, promptly after receipt of notice of
commencement of any action, suit or proceeding against such party in respect of
which a claim for contribution may be made against another party or parties,
notify each party or parties from whom contribution may be sought, but the
omission to so notify such party or parties shall not relieve the party or
parties from whom contribution may be sought from any obligation it or they may
have under this Section 8 or otherwise. No party shall be liable for
contribution with respect to any action or claim settled without its consent;
PROVIDED, HOWEVER, that such consent was not unreasonably withheld.

      9. DEFAULT BY AN UNDERWRITER.

            (a) If any Underwriter or Underwriters shall default in its or their
      obligation to purchase Firm Shares or Additional Shares hereunder, and if
      the Firm Shares or Additional Shares with respect to which such default
      relates do not (after giving effect to arrangements, if any, made by you
      pursuant to subsection (b) below) exceed in the aggregate 10% of the
      number of Firm Shares or Additional Shares, to which the default relates
      shall be purchased by the non-defaulting Underwriters in proportion to the
      respective proportions which the numbers of Firm Shares set forth opposite
      their 


                                       22



      respective names in Schedule I hereto bear to the aggregate number of Firm
      Shares set forth opposite the names of the non-defaulting Underwriters.

            (b) In the event that such default relates to more than 10% of the
      Firm Shares or Additional Shares, as the case may be, the Representatives
      may in their discretion arrange for the Representatives or for another
      party or parties (including any non-defaulting Underwriter or Underwriters
      who so agree) to purchase such Firm Shares or Additional Shares, as the
      case may be, to which such default relates on the terms contained herein.
      In the event that within five calendar days after such a default the
      Representatives do not arrange for the purchase of the Firm Shares or
      Additional Shares, as the case may be, to which such default relates as
      provided in this Section 9, this Agreement or, in the case of a default
      with respect to the Additional Shares, the obligations of the Underwriters
      to purchase and of the Company to sell the Additional Shares shall
      thereupon terminate, without liability on the part of the Company with
      respect thereto (except in each case as provided in Section 5, 7(a) and 8
      hereof) or the Underwriters, but nothing in this Agreement shall relieve a
      defaulting Underwriter or Underwriters of its or their liability, if any,
      to the other Underwriters and the Company for damages occasioned by its or
      their default hereunder.

            (c) In the event that the Firm Shares or Additional Shares to which
      the default relates are to be purchased by the non-defaulting
      Underwriters, or are to be purchased by another party or parties as
      aforesaid, the Representatives or the Company shall have the right to
      postpone the Closing Date or the applicable Additional Closing Date, as
      the case may be, for a period, not exceeding five business days, in order
      to effect whatever changes may thereby be made necessary in the
      Registration Statement or the Prospectus or in any other documents and
      arrangements, and the Company agrees to file promptly any amendment or
      supplement to the Registration Statement or the Prospectus which, in the
      opinion of Underwriters' Counsel, may thereby be made necessary or
      advisable. The term 'Underwriter' as used in this Agreement shall include

warranties, covenants and agreements of the Underwriters and the Company
contained in this Agreement, including the agreements contained in Section 5,

delivery of and payment for the Shares to and by the Underwriters. The

      11. EFFECTIVE DATE OF AGREEMENT; TERMINATION.

            (a) This Agreement shall become effective upon the later of when (i)
      the Representatives and the Company shall have received notification of
      the effectiveness of the Registration Statement and (ii) the execution of
      this Agreement. If either the initial public offering price or the
      purchase price per Offered Share has not been agreed upon prior to 5:00
      P.M., New York time, on the fifth full business day after the Registration
      Statement shall have become effective, this Agreement shall thereupon
      terminate without liability to the Company or the Underwriters except as
      herein expressly provided. Until this Agreement becomes effective as
      aforesaid, it may be terminated by the Company by notifying you or by the
      Representatives notifying the Company. Notwithstanding the foregoing, the
      provisions of this Section 11 and of Section 1, 5, 7 and 8 hereof shall at
      all times be in full force and effect.

            (b) You shall have the right to terminate this Agreement at any time
      prior to the Closing Date or the obligations of the Underwriters to
      purchase Additional Shares at any time prior to the applicable Additional
      Closing Date, as the case may be, if (A) any domestic or international
      event or act or occurrence has materially disrupted, or in the opinion of
      the Representatives will in the immediate future materially disrupt, the
      market for the Company's securities or securities in general; or (B) if
      trading on the New York Stock Exchange or the Nasdaq Stock Market shall
      have been suspended, or minimum or maximum prices for trading shall have
      been fixed, or maximum ranges for prices for securities shall have been
      required, on the New York Stock Exchange or the Nasdaq Stock Market by the
      New York Stock Exchange, the National Association of Securities Dealers,
      Inc. or by order of the Commission or any other governmental authority
      having jurisdiction; or (C) if a banking moratorium has been declared by a
      state or federal authority or if any new restriction materially adversely
      affecting the distribution of the Firm Shares or the Additional Shares, as
      the case may be, shall have become effective; or (D) (i) if the United
      States becomes engaged in hostilities or there is an escalation of
      hostilities involving the United States or there is a declaration of a
      national emergency or war by the United States or (ii) if there shall have
      been such change in political, financial or economic conditions, if the
      effect of any such event in (i) or (ii) as in the judgment of the
      Representatives makes it impracticable or inadvisable to proceed with the
      offering, sale and delivery of the Firm Shares or the Additional Shares,
      as the case may be, on the terms contemplated by the Prospectus.

            (c) Any notice of termination pursuant to this Section 11 shall be
      by telephone, telex or telegraph, confirmed in writing by letter.

            (d) If this Agreement shall be terminated pursuant to any of the
      provisions hereof (otherwise than pursuant to (i) notification by the
      Representatives as provided in Section 11(a) hereof or (ii) Section 9(b)
      or 11(b) hereof), or if the sale of the Offered Shares provided for herein
      is not consummated because any condition to the obligations of the
      Underwriters set forth herein is not satisfied or because of any refusal,
      inability or failure on the part of the Company to perform any agreement
      herein or comply with any provision hereof, the Company will, subject to
      demand by the Representatives, reimburse 


                                       24
