          -------------------------                                            
Initial Purchasers as follows:

          (a) To advise the Initial Purchasers promptly and, if requested by the
     Initial Purchasers, confirm such advice in writing of; (i) the issuance by
     any state securities commission of any stop order suspending the
     qualification or exemption from qualification of any Securities for
     offering or sale in any jurisdiction, or the initiation of any proceeding
     for such purpose by any state securities commission or other regulatory
     authority; and (ii) the happening of any event that, in the reasonable
     opinion of either counsel to the Company or counsel to the Initial
     Purchasers, makes any statement of a material fact made in the Preliminary
     Offering Memorandum or the Offering Memorandum untrue or that requires the
     making of any additions to or changes in the Preliminary Offering
     Memorandum or the Offering Memorandum in order to make the statements
     therein, in the light of the circumstances under which they are made, not
     misleading. The Company shall use its best efforts to prevent the issuance
     of any stop order or order suspending the qualification or exemption of any
     Securities under any state securities or Blue Sky laws and, if at any time
     any state securities commission or other regulatory authority shall issue
     an order suspending the qualification or exemption of any Securities under
     any state securities or Blue Sky laws, the Company shall use its best
     efforts to obtain the withdrawal or lifting of such order at the earliest
     possible time.

          (b) To furnish the Initial Purchasers and those persons identified
     by the Initial Purchasers to the Company, without charge, as many copies of
     the Preliminary Offering Memorandum and the Offering Memorandum, and any
     amendments or supplements thereto, as the Initial Purchasers may reasonably
     request. The Company consents to the use of the Preliminary Offering
     Memorandum and the Offering Memorandum, and any amendments and supplements
     thereto required pursuant hereto, by the Initial Purchasers in connection
     with Exempt Resales.

          (c) Not to amend or supplement the Preliminary Offering Memorandum
         or the Offering Memorandum prior to the Closing Date unless the Initial
     Purchasers shall previously have been advised thereof and shall not have
     objected thereto within a reasonable time after being furnished a copy
     thereof. The Company shall promptly prepare, upon the Initial Purchasers'
     request, any amendment or supplement to the Preliminary Offering Memorandum
     or the Offering Memorandum that may be necessary or reasonably requested by
     the Initial Purchasers in connection with Exempt Resales.

          (d) If, after the date hereof and prior to consummation of any Exempt
    Resale, any event shall occur as a result of which, in the judgment of the
    Company or in the reasonable opinion of either counsel to the Company or
    counsel to the Initial Purchasers, it becomes necessary or advisable to
    amend or supplement the Preliminary Offering Memorandum or Offering
    Memorandum in order to make the statements therein, in the light of the
    circumstances when such Offering Memorandum is delivered to an Eligible
    Purchaser which is a prospective purchaser, not misleading, or if it is
    necessary or advisable to amend or supplement the Preliminary Offering
    Memorandum or Offering Memorandum to comply with applicable law, (i) notify
    the Initial Purchasers and (ii) forthwith to prepare an appropriate
    amendment or supplement to such Offering

                                       4

 
    Memorandum so that the statements therein as so amended or supplemented will
    not, in the light of the circumstances when it is so delivered, be
    misleading, or so that such Offering Memorandum will comply with applicable
    law.

          (e) To cooperate with the Initial Purchasers and counsel to the
    Initial Purchasers in connection with the qualification or registration of
    the Units, the Series A Senior Notes and the Warrants under the securities
    or Blue Sky laws of such jurisdictions as the Initial Purchasers may
    reasonably request and to continue such qualification in effect so long as
    required for the Exempt Resales; provided that the Company shall not be
    required to take any action that would subject it to service of process in
    suits or taxation, other than as to matters and transactions relating to the
    Preliminary Offering Memorandum, the Offering Memorandum or Exempt Resales,
    in any jurisdiction where it is not now so subject.

          (f) Whether or not the transactions contemplated by this Agreement
    are consummated or this Agreement becomes effective or is terminated, to pay
    all costs, expenses, fees and taxes incident to the performance of the
    obligations of the Company hereunder, including in connection with: (i) the

     and all courts and other tribunals (each an "Authorization") necessary to
                                                  -------------
     engage in the business as presently conducted by any of them in the manner
     described in the Offering Memorandum, except as described in the Offering
     Memorandum or where failure to hold such Authorizations would not,
     individually or in the aggregate, have a Material Adverse Effect and (iv)
     no reason to believe that any governmental body or agency is considering
     limiting, suspending or revoking any such Authorization. Except where the
     failure to be in full force and effect would not have a Material Adverse
     Effect, all such Authorizations are valid and in full force and effect and
     each of the Company, the Subsidiaries and the Joint Ventures is in
     compliance with the terms and conditions of all such Authorizations and
     with the rules and regulations of the regulatory authorities having
     jurisdiction with respect thereto. All leases to which the Company, the
     Subsidiaries and the Joint Ventures is a party are valid and binding and no
     default by the Company, any Subsidiary or any Joint Venture has occurred
     and is continuing thereunder and no defaults by the landlord are existing
     under any such lease that could reasonably be expected to result in a
     Material Adverse Effect.

          (xxiv) Each of the Company, the Subsidiaries and the Joint Ventures
     owns, possesses or has the right to employ all patents, patent rights,
     licenses (including all FCC, state, local or other jurisdictional
     regulatory licenses), inventions, copyrights, know-how (including trade
     secrets and other unpatented and/or unpatentable proprietary or
     confidential information, software, systems or procedures), trademarks,
     service marks and trade names, inventions, computer programs, technical
     data and information (collectively, the "Intellectual Property") presently
                                              ---------------------
     employed by the Company, its Subsidiaries or the Joint Ventures in
     connection with the businesses now operated by it or which are proposed to
     be operated by the Company, its Subsidiaries or the Joint Ventures free and
     clear of and without violating any right, claimed right, charge,
     encumbrance, pledge, security interest, restriction or lien of any kind of
     any other person and none of the Company, any Subsidiary or any Joint
     Venture has received any notice of infringement of or conflict with
     asserted rights of others with respect to any of the foregoing except as
     could not reasonably be expected to have a Material Adverse Effect. The use
     of the Intellectual Property in connection with the business and operations
     of the Company, the Subsidiaries and the Joint Ventures does not infringe
     on the rights of any person, except would not have a Material Adverse
     Effect.

          (xxv) None of the Company, any Subsidiary, any Joint Venture or any of
     their respective officers, directors, partners, employees, agents or
     affiliates or any other person acting on behalf of the Company, any
     Subsidiary or any Joint Venture, as the case may be, has, directly or
     indirectly, given or agreed to give any money, gift or similar benefit
     (other than legal price concessions to customers in the ordinary course of
     business) to any customer, supplier, employee or agent of a customer or
     supplier, official or employee of any governmental agency (domestic or
     foreign), instrumentality of any government (domestic or foreign) or any
     political party or candidate for office (domestic or foreign) or other
     person who was, is or may be in a position to help or hinder the business
     of the Company, any Subsidiary or any Joint Venture (or assist the

                                      12

 
     Company, any Subsidiary or any Joint Venture in connection with any actual
     or proposed transaction) which (i) might subject the Company, any
     Subsidiary, or any other individual or entity to any damage or penalty in
     any civil, criminal or governmental litigation or proceeding (domestic or
     foreign), (ii) if not given in the past, could reasonably be expected to
     have had a Material Adverse Effect on the assets, business or operations of
     the Company, any Subsidiary or any Joint Venture or (iii) if not continued
     in the future, could reasonably be expected to have a Material Adverse
     Effect.

          (xxvi) All tax returns required to be filed by the Company, each of
     the Subsidiaries and each of the Joint Ventures in all jurisdictions have
     been so filed. All taxes, including withholding taxes, penalties and
     interest, assessments, fees and other charges due or claimed to be due from
     such entities or that are due and payable have been paid, other than those
     being contested in good faith and for which adequate reserves have been
     provided or those currently payable without penalty or interest. There are
     no proposed additional tax assessments against the Company, any Subsidiary,
     any Joint Venture or the assets or property of the Company, any Subsidiary
     or any Joint Venture.

          (xxvii) None of the Company, the Subsidiaries or the Joint Ventures is
     (i) an "investment company" or a company "controlled" by an "investment
     company" within the meaning of the Investment Company Act of 1940, as
     amended (the "Investment Company Act"), or (ii) a "holding company" or a
                   ----------------------
     "subsidiary company" or an "affiliate" of a holding company within the
     meaning of the Public Utility Holding Company Act of 1935, as amended (the
     "PUC Act"), except for TCG Pittsburgh, a New York general partnership ("TGC
     Pittsburgh").

          (xxviii) There are no holders of securities of the Company, the
     Subsidiaries or the Joint Ventures who, by reason of the execution by the
     Company of this Agreement or any other Operative Document to which it is a
     party or the consummation by the Company of the transactions contemplated
     hereby and thereby, have the right to request or demand that the Company,
     any of the Subsidiaries or any of the Joint Ventures register any of its
     securities under the Act.

          (xxix) Each of the Company, the Subsidiaries and the Joint Ventures
     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
     accountability for assets; (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 thereto.

          (xxx) Each of the Company, the Subsidiaries and the Joint Ventures
     maintains insurance covering its properties, operations, personnel and
     businesses. Such insurance insures against such losses and risks as are
     adequate in accordance with customary industry practice to protect the
     Company, the Subsidiaries, the Joint Ventures and their respective
     businesses. None of the Company, any Subsidiary or any Joint Venture has
     received notice from any insurer or agent of such insurer that substantial
     capital improvements or other expenditures will have to be made in order to
     continue such insurance. All such insurance is outstanding and duly in
     force on the date hereof.

          (xxxi) None of the Company, any Subsidiary or any Joint Venture has
     (i) taken, directly or indirectly, any action designed to, or that might
     reasonably be expected to, cause or result in

                                      13

 
     stabilization or manipulation of the price of any security of the Company
     to facilitate the sale or resale of the Units, the Senior Notes or the
     Warrants or (ii) since the date of the Preliminary Offering Memorandum (A)
     sold, bid for, purchased or paid any person any compensation for soliciting
     purchases of, the Units, the Senior Notes or the Warrants or (B) paid or
     agreed to pay to any person any compensation for soliciting another to
     purchase any other securities of the Company.

          (xxxii) No registration under the Act of the Units, the Senior Notes
     or the Warrants is required for the sale of the Units to the Initial
     Purchasers as contemplated hereby or for the Exempt Resales assuming (i)
     that the purchasers who buy the Units in the Exempt Resales are either QIBs
     or Accredited Investors and (ii) the accuracy of the Initial Purchasers'
     representations regarding the absence of general solicitation in connection
     with the sale of Units to the Initial Purchasers and the Exempt Resales
     contained herein. No form of general solicitation or general advertising
     was used by the Company or any of its representatives (other than the
     Initial Purchasers, as to which the Company makes no representation or
     warranty) in connection with the offer and sale of any of the Securities in
     connection with Exempt Resales, including, but not limited to, articles,
     notices or other communications published in any newspaper, magazine, or
     similar medium or broadcast over television or radio, or any seminar or
     meeting whose attendees have been invited by any general solicitation or
     general advertising. No securities of the same class as the Securities have
     been issued and sold by the Company within the six-month period immediately
     prior to the date hereof.

          (xxxiii) Set forth on Exhibit C hereto is a list of each employee
                                ---------
     pension or benefit plan with respect to which the Company or any
     corporation considered an affiliate of the Company within the meaning of
     Section 407(d)(7) of ERISA (an "ERISA Affiliate") is a party in interest or
                                     ---------------
     disqualified person. The execution and delivery of this Agreement, the
     other Operative Documents and the sale of the Units to be purchased by the
     QIBs and the Accredited Investors will not involve any prohibited
     transaction within the meaning of Section 406 of ERISA or Section 4975 of
     the Internal Revenue Code of 1986. The representation made by the Company
     in the preceding sentence is made in reliance upon and subject to the
     accuracy of, and compliance with, the representations and covenants made or
     deemed made by the QIBs and the Accredited Investors as set forth in the
     Offering Memorandum under the caption "Notice to Investors."

          (xxxiv) Each of the Preliminary Offering Memorandum and the Offering
     Memorandum, as of its date, and each amendment or supplement thereto, as of
     its date, contains the information specified in, and meets the requirements
     of, Rule 144A(d)(4) under the Act.

          (xxxv) Subsequent to the respective dates as of which information is
     given in the Offering Memorandum and up to the Closing Date, except as set
     forth in the Offering Memorandum, (i) none of the Company, any Subsidiary
     or any Joint Venture has incurred any liabilities or obligations, direct or
     contingent, which are material, individually or in the aggregate, to the
     Company, the Subsidiaries and the Joint Ventures taken as a whole, nor
     entered into any transaction not in the ordinary course of business, (ii)
     there has not been, singly or in the aggregate, any change or development
     which could reasonably be expected to result in a Material Adverse Effect,
     (iii) there has been no dividend or distribution of any kind declared, paid
     or made by the Company or its Subsidiaries on any class of capital stock
     and (iv) there has been no distribution of profits or return of capital
     contribution by any Joint Venture.

          (xxxvi) None of the execution, delivery and performance of this
     Agreement, the issuance and sale of the Securities, the application of the
     proceeds from the issuance and sale of the Securities and the consummation
     of the transactions contemplated thereby as set forth in the

                                      14

 
     Offering Memorandum, will violate Regulations G, T, U or X promulgated by
     the Board of Governors of the Federal Reserve System or analogous foreign
     laws and regulations.

          (xxxvii) The accountants who have certified or will certify the
     financial statements included or to be included as part of the Offering
     Memorandum are independent accountants. The historical financial statements
     of the Company and each of the Subsidiaries comply as to form in all
     material respects with the requirements applicable to registration
     statements on Form S-4 under the Act and present fairly in all material
     respects the financial position and results of operations of the Company
     and each of its Subsidiaries, at the respective dates and for the
     respective periods indicated. Such financial statements have been prepared
     in accordance with generally accepted accounting principles applied on a
     consistent basis throughout the periods presented. The other financial
     information and data included in the Offering Memorandum, historical and
     pro forma, are accurately presented in all material respects and prepared
     on a basis consistent with the financial statements, historical and pro
     forma, included in the Offering Memorandum and the books and records of the
     Company, each of its Subsidiaries and each of its Joint Ventures, as
     applicable. The statistical information and data included in the Offering
     Memorandum are accurately presented in all material respects.

          (xxxviii) The Company does not intend to, nor does it believe that it
     will, incur debts beyond its ability to pay such debts as they mature. The
     present fair saleable value of the assets of the Company on a consolidated
     basis exceeds the amount that will be required to be paid on or in respect
     of the existing debts and other liabilities (including contingent
     liabilities) of the Company on a consolidated basis as they become absolute
     and matured. The assets of the Company on a consolidated basis do not
     constitute unreasonably small capital to carry out the business of the
     Company, the Subsidiaries and the Joint Ventures, taken as a whole, as
     conducted or as proposed to be conducted. Upon the issuance of the Units,
     the present fair saleable value of the assets of the Company on a
     consolidated basis will exceed the amount that will be required to be paid
     on or in respect of the existing debts and other liabilities (including
     contingent liabilities) of the Company on a consolidated basis as they
     become absolute and matured. Upon the issuance of the Units, the assets of
     the Company on a consolidated basis will not constitute unreasonably small
     capital to carry out its businesses as now conducted, including the capital
     needs of the Company on a consolidated basis, taking into account the
     projected capital requirements and capital availability.

          (xxxix) Except pursuant to this Agreement, there are no contracts,
     agreements or understandings between the Company, any of its Subsidiaries
     or any of its Joint Ventures and any other person that would give rise to a
     valid claim against the Company or either of the Initial Purchasers for a
     brokerage commission, finder's fee or like payment in connection with the
     issuance, purchase and sale of the Securities.

          (xl) Each of the Company, the Subsidiaries and the Joint Ventures has
     complied with all provisions of Section 517.075, Florida Statutes, relating
     to doing business with the Government of Cuba or with any affiliate located
     in Cuba.

          (xli) Except as disclosed in the Offering Memorandum, there are no
     business relationships or related party transactions required to be
     disclosed therein pursuant to Item 404 of Regulation S-K of the Commission
     (assuming for purposes of this paragraph 5(xli) that Regulation S-K is
     applicable to the Offering Memorandum).

          (xlii) Each of the Company and Hyperion Telecommunications of
     Pennsylvania, Inc. will be released from all of their obligations under the
     agreement governing the TCG Pittsburgh Joint

                                      15

 
     Venture pursuant to an amendment to such partnership agreement to be
     effective as of January 1, 1995, which amendment shall be promptly
     executed.

          Each certificate signed by any officer of the Company and delivered to
the Initial Purchasers or counsel for the Initial Purchasers pursuant to this
Agreement shall be deemed to be a representation and warranty by the Company to
the Initial Purchasers as to the matters covered thereby.

          The Company acknowledges that each of the Initial Purchasers and, for
purposes of the opinions to be delivered to the Initial Purchasers pursuant to
Section 8 hereof, counsel to the Company and counsel to the Initial Purchasers,
will rely upon the accuracy and truth of the foregoing representations and
hereby consents to such reliance.

     (b) Each of the Initial Purchasers severally and not jointly represents,
warrants and covenants to the Company and agrees that:

          (i) Such Initial Purchaser is a QIB, with such knowledge and
     experience in financial and business matters as are necessary in order to
     evaluate the merits and risks of an investment in the Units.

          (ii) Such Initial Purchaser (A) is not acquiring the Units with a view
     to any distribution thereof that would violate the Act or the securities
     laws of any state of the United States or any other applicable jurisdiction
     and (B) will be reoffering and reselling the Units only to QIBs in reliance
     on the exemption from the registration requirements of the Act provided by
     Rule 144A and to Accredited Investors in a private placement exempt from
     the registration requirements of the Act.

          (iii) No form of general solicitation or general advertising has been
     or will be used by any of the Initial Purchasers or any of their
     representatives in connection with the offer and sale of any of the Units,
     including, but not limited to, articles, notices or other communications
     published in any newspaper, magazine, or similar medium or broadcast over
     television or radio, or any seminar or meeting whose attendees have been
     invited by any general solicitation or general advertising.

          (iv) In connection with the Exempt Resales, such Initial Purchaser
     will solicit offers to buy the Units only from, and will offer to sell the
     Units only to, QIBs and Accredited Investors. Such Initial Purchaser
     further agreed (A) that it will offer to sell the Units only to, and will
     solicit offers to buy the Units only from (1) QIB's who in purchasing such
     Units will be deemed to have represented and agreed that they are
     purchasing the Units for their own accounts or accounts with respect to
     which they exercise sole investment discretion and that they or such
     accounts are QIBs and (2) Accredited Investors who make the representations
     contained in, and execute and return to one of the Initial Purchasers, a
     certificate in the form of Annex A attached to the Offering Memorandum and
                                -------
     (B) that, in the case of such QIBs and Accredited Investors, acknowledges
     and agrees that such Units will not have been registered under the Act and
     may be resold, pledged or otherwise transferred only (x)(I) to a person who
     the seller reasonably believes is a QIB in a transaction meeting the
     requirements of Rule 144A or (II) in a transaction meeting the requirements
     of Rule 144 or (III) in accordance with another exemption from the
     registration requirements of the Act (and based upon an opinion of counsel
     if the Company so requests), (y) to the Company or (z) pursuant to an
     effective registration statement under the Act and, in each case, in
     accordance with any applicable securities laws of any state of the United
     States or any other applicable jurisdiction and (C) that the holder will,
     and each subsequent holder is required to, notify any purchaser of the
     security evidenced thereby of the resale restrictions set forth in (B)
     above.

                                      16

 
          Each of the Initial Purchasers understands that the Company and, for
     purposes of the opinions to be delivered to the Initial Purchasers pursuant
     to Section 8 hereof, counsel to the Company and counsel to the Initial
     Purchasers will rely upon the accuracy and truth of the foregoing
     representations and hereby expressly consents to such reliance.

     6.   Indemnification.
          ---------------

          (a) The Company and its Subsidiaries, jointly and severally, agree to
     indemnify and hold harmless (i) each Initial Purchaser, (ii) each person,
     if any, who controls an Initial Purchaser within the meaning of Section 15
     of the Act or Section 20(a) of the Exchange Act and (iii) the respective
     officers, directors, partners, employees, representatives and agents of any
     Initial Purchaser or any controlling person to the fullest extent lawful,
     from and against any and all losses, liabilities, claims, damages and
     expenses whatsoever (including but not limited to attorneys' fees and any
     and all expenses whatsoever incurred in investigating, preparing or
     defending against any investigation or 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 Preliminary
     Offering Memorandum or the Offering Memorandum, 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, in the light
     of the circumstances under which they were made, not misleading; provided
     that the Company will not be liable in any such case to the extent, but
     only to the extent, that (i) 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 the Initial Purchasers expressly for use therein and (ii)
     the foregoing indemnity with respect to any untrue statement contained in
     or omitted from the Preliminary Offering Memorandum shall not inure to the
     benefit of any Initial Purchaser (or any person controlling such Initial
     Purchasers), from whom the person asserting any such loss, liability,
     claim, damage or expense purchased any of the Units which are the subject
     thereof if it is finally judicially determined that such loss, liability,
     claim, damage or expense resulted solely from the fact that such Initial
     Purchaser sold Units to the person asserting such loss, liability, claim,
     damage or expense, who was not sent or given, at or prior to the written
     confirmation of such sale, a copy of the Offering Memorandum, as amended or
     supplemented, and (x) the Company shall have previously and timely
     furnished sufficient copies of the Offering Memorandum, as so amended or
     supplemented, to such Initial Purchaser in accordance with this Agreement
     and (y) the Offering Memorandum, as so amended or supplemented, would have
     completely corrected such untrue statement or omission of a material fact.
     This indemnity agreement will be in addition to any liability which the
     Company may otherwise have, including, under this Agreement.

          (b) Each Initial Purchaser, severally and not jointly, 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 Act or Section
     20(a) of the Exchange Act, against any losses, liabilities, claims, damages
     and expenses whatsoever (including but not limited to attorneys' fees and
     any and all expenses whatsoever incurred in investigating, preparing or
     defending against any investigation or 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


                                      17

 
     statement or alleged untrue statement of a material fact contained in the
     Preliminary Offering Memorandum or the Offering Memorandum, 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, in the
     light of the circumstances under which they were made, 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
     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 Initial
     Purchaser expressly for use therein; provided that in no case shall any
     Initial Purchaser be liable or responsible for any amount in excess of the
     discounts and commissions received by such Initial Purchasers, as set forth
     on the cover page of the Offering Memorandum. This indemnity will be in
     addition to any liability which any of the Initial Purchasers may otherwise
     have, including under this Agreement.

          (c) 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 6 except
     to the extent that it has been actually prejudiced in any material respect
     by such failure or from any liability which it may otherwise have). 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 reasonably 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 the indemnifying parties in connection with the
     defense of such action, (ii) the indemnifying parties shall not have
     employed counsel to take 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 party or 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 of counsel shall be borne by the
     indemnifying parties. The indemnifying party under subsection (a) or (b)
     above, shall only be liable for the legal expenses of one counsel (in
     addition to any local counsel) for all indemnified parties in each
     jurisdiction in which any claim or action is brought; provided that the
     indemnifying party shall be liable for separate counsel for any indemnified
     party in a jurisdiction, if counsel to the indemnified parties shall have
     reasonably concluded that there may be defenses available to such
     indemnified party that are difference from or additional to those available
     to one or more of the other indemnified parties and that separate counsel
     for such indemnified party is prudent under the circumstances. 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 prior written consent; provided that such consent was not
     unreasonably withheld.

     7. Contribution. In order to provide for contribution in circumstances in
        ------------
which the indemnification provided for in Section 6 is for any reason held to be
unavailable from the Company or is insufficient to hold harmless a party
indemnified thereunder, the Company and the Initial Purchasers shall contribute
to the aggregate losses, claims, damages, liabilities and expenses of the nature
contemplated

                                      18

 
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
Initial Purchasers, 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) to which the Company and one or more of the Initial
Purchasers may be subject, in such proportion as is appropriate to reflect the
relative benefits received by the Company and the Initial Purchasers from the
offering of the Units 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 6, 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 Initial Purchasers 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 by the Company and the Initial Purchasers shall
be deemed to be in the same proportion as (x) the total proceeds from the
offering of Units (net of discounts but before deducting expenses) received by
the Company and (y) the discounts received by the Initial Purchasers,
respectively, in each case as set forth in the table on the cover page of the
Offering Memorandum. The relative fault of the Company and of the Initial
Purchasers 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 Initial Purchasers and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The Company and the Initial Purchasers agree that it would not be just and
equitable if contribution pursuant to this Section 7 were determined by pro rata
allocation or by any other method of allocation which does not take into account
the equitable considerations referred to above. Notwithstanding the provisions
of this Section 7, (i) in no case shall any Initial Purchaser be required to
contribute any amount in excess of the amount by which the discount applicable
to the Units purchased by such Initial Purchaser pursuant to this Agreement
exceeds the amount of any damages which such Initial Purchaser has otherwise
been required to pay by reason of any untrue or alleged untrue statement or
omission or alleged omission 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. For purposes of this Section 7, (A) each person, if any, who
controls any Initial Purchaser within the meaning of Section 15 of the Act or
Section 20(a) of the Exchange Act and (B) the respective officers, directors,
partners, employees, representatives and agents of any Initial Purchaser or any
controlling person shall have the same rights to contribution as such Initial
Purchaser, 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 shall have the
same rights to contribution as the Company, subject in each case to clauses (i)
and (ii) of this Section 7. 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 under this Section 7, notify such party or
parties from whom contribution may be sought, but the failure 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 7 or
otherwise. No party shall be liable for contribution with respect to any action
or claim settled without its prior written consent; provided that such written
consent was not unreasonably withheld.

          (a) This Agreement shall become effective upon execution and delivery

          (b) The Initial Purchasers shall have the right to terminate this
     Agreement at any time prior to the Closing Date by notice to the Company
     from the Initial Purchasers, without liability (other than with respect to

     expenses), or if the sale of the Units provided for herein is not
     consummated because any condition to the obligations of the Initial
     Purchasers 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 Initial Purchasers, reimburse the Initial Purchasers for all
     out-of-pocket expenses (including the reasonable fees and expenses of

of the Company, representatives of the independent certified public accountants
of the Company, the Initial Purchasers and the representatives of the Initial

responsibility for, the accuracy, completeness or fairness of the statements
contained in the Preliminary Offering Memorandum or the Offering Memorandum
