set opposite that Underwriter's name in Schedule l hereto. Each Underwriter
shall be obligated to purchase from the Company, and from each Selling
Stockholder, that number of shares of the Firm Stock which represents the same
proportion of the number of shares of the Firm Stock to be sold by the Company,
and by each Selling Stockholder, as the number of shares of the Firm Stock set
forth opposite the name of such Underwriter in Schedule l represents of the
total number of shares of the Firm Stock to be purchased by all of the
Underwriters pursuant to this Agreement. The respective purchase obligations of
the Underwriters with respect to the Firm Stock shall be rounded among the
Underwriters to avoid fractional shares, as the Representatives may determine.

     In addition, the Company and the Selling Stockholders grant to the
Underwriters an option to purchase up to [__________] shares of Option Stock.
Such option is granted solely for the purpose of covering overallotments in the
sale of Firm Stock and is exercisable as provided in Section 5 hereof. Shares of
Option Stock shall be purchased severally for the account of the Underwriters in
proportion to the number of shares of Firm Stock set opposite the name of such
Underwriters in Schedule l hereto. The respective purchase obligations of each
Underwriter with respect to the Option Stock shall be adjusted by the
Representatives so that no Underwriter shall be obligated to purchase Option
Stock other than in l00 share amounts. The price of both the Firm Stock and any
Option Stock shall be [______] per share.

     The Company and the Selling Stockholders shall not be obligated to deliver
any of the Stock to be delivered on the First Delivery Date or the Second
Delivery Date (as hereinafter defined), as the case may be, except upon payment
for all the Stock to be purchased on such Delivery Date as provided herein.

     4. Offering of Stock by the Underwriters. Upon authorization by the
Representatives of the release of the Firm Stock, the several Underwriters
propose to offer the Firm Stock for sale upon the terms and conditions set forth
in the Prospectus.

     5. Delivery of and Payment for the Stock. Delivery of and payment for the
Firm Stock shall be made at the office of Chadbourne & Parke LLP, 30 Rockefeller
Plaza, New York, New York 10112, at 10:00 A.M., New York City time, on the third
full business day following the date of this Agreement or at such other date or
place as shall be determined by agreement between the Representatives and the
Company. This date and time are sometimes referred to as the First Delivery
Date. On the First Delivery Date, the Company and the Selling Stockholders shall
deliver or cause to be delivered certificates representing the Firm Stock to the
Representatives for the account of each Underwriter against payment to or upon
the order of the Company and the Selling Stockholders of the purchase price by
wire transfer in immediately available funds. Time shall be of the essence, and
delivery at the time and place specified pursuant to this Agreement is a further
condition of the obligation of each Underwriter hereunder. Upon delivery, the
Firm Stock shall be registered in such names and in such denominations as the
Representatives shall request in writing not less than two full business days
prior to the First Delivery Date. For the purpose of expediting the checking and
packaging of the certificates for the Firm Stock, the Company and the Selling
Stockholders shall make the certificates representing the Firm Stock available

     The option granted in Section 3 will expire 30 days after the date of this
Agreement and may be exercised in whole or in part from time to time by written
notice being given to the Company by the Representatives. Such notice shall set
forth the aggregate number of shares of Option Stock as to which the option is
being exercised, the names in which the shares of Option Stock are to be
registered, the denominations in which the shares of Option Stock are to be
issued and the date and time, as determined by the Representatives, when the
shares of Option Stock are to be delivered; provided, however, that this date
and time shall not be earlier than the First Delivery Date nor earlier than the
second business day after the date on which the option shall have been exercised
nor later than the fifth business day after the date on which the option shall
have been exercised. The date and time the shares of Option Stock are delivered
are sometimes referred to as the "Second Delivery Date" and the First Delivery
Date and the Second Delivery Date are sometimes each referred to as a "Delivery
Date."

     Delivery of and payment for the Option Stock shall be made at the place
specified in the first sentence of the first paragraph of this Section 5 (or at
such other place as shall be determined by agreement between the Representatives
and the Company) at 10:00 A.M., New York City time, on the Second Delivery Date.
On the Second Delivery Date, the Company and the Selling Stockholders shall

     but without independent check or verification, no facts have come to the
     attention of such counsel which lead it to believe that (I) the
     Registration Statement, as of the Effective Date, contained any

                                      -18-




     untrue statement of a material fact or omitted to state a material fact
     required to be stated therein or necessary in order to make the statements
     therein not misleading, or that the Prospectus contains any untrue
     statement of a material fact or omits to state a 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 or
     (II) any documents incorporated by reference in the Prospectus or any
     further amendment or supplement to any such incorporated document made by
     the Company prior to such Delivery Date, when they were filed with the
     Commission contained an untrue statement of a material fact or omitted 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. The
     foregoing statement may be qualified by a statement to the effect that such
     counsel does not (i) assume any responsibility for the accuracy,
     completeness or fairness of the statements contained in the Registration
     Statement or the Prospectus or (ii) express any view as to the financial
     statements and schedules and other financial data contained therein.

         (e) Hale and Dorr shall have furnished to the Representatives its
     written opinion, as special counsel to the Selling Stockholders, which
     opinion shall be addressed to the Underwriters and dated such Delivery
     Date, in form and substance reasonably satisfactory to the Representatives,
     to the effect that:

         (i) Each Selling Stockholder has full right, power and authority to
     enter into this Agreement and the Custody Agreement and Power of Attorney;
     to such counsel's knowledge, no consent, approval, authorization or order
     of any court or governmental agency or body is required for the execution
     and delivery and performance of this Agreement and the Custody Agreement
     and Power of Attorney by each Selling Stockholder, and consummation by the
     Selling Stockholders of the transactions contemplated thereby, except such
     as have been obtained or made and are in full force and effect and such as
     may be required by the NASD or under the Exchange Act and applicable state
     securities laws;

         (ii) This Agreement has been duly authorized, executed and delivered by
     or on behalf of each Selling Stockholder;

         (iii) A Custody Agreement and Power of Attorney have been duly
     authorized, executed and delivered by each Selling Stockholder and
     constitute valid and binding agreements of each Selling Stockholder,
     enforceable in accordance with their respective terms;

         (iv) Immediately prior to the Delivery Date, each Selling Stockholder
     had good and valid title to the shares of Stock to be sold by such Selling
     Stockholder under this Agreement, free and clear of all liens,
     encumbrances, equities or claims, and full right, power and authority to
     sell, assign, transfer and deliver such shares to be sold by such Selling
     Stockholder hereunder; and

                                      -19-




         (v) Good and valid title to the shares of Stock to be sold by each
     Selling Stockholder under this Agreement, free and clear of all liens,
     encumbrances, equities or claims, has been transferred to each of the
     several Underwriters.

     In rendering such opinion, such counsel may (i) state that its opinion
     is limited to matters governed by the Federal laws of the United States of
     America and the Delaware General Corporate Law and (ii) in rendering the
     opinion in Section 9(e)(iv) above, rely upon a certificate of each Selling
     Stockholder in respect of matters of fact as to ownership of and liens,
     encumbrances, equities or claims on the shares of Stock sold by such
     Selling Stockholder, provided that such counsel shall furnish copies
     thereof to the Representatives and state that it believes that both the
     Underwriters and it are justified in relying upon such certificate.

         (f) The Representatives shall have received from Chadbourne & Parke
     LLP, counsel for the Underwriters, such opinion or opinions, dated such
     Delivery Date, with respect to the issuance and sale of the Stock, the
     Registration Statement, the Prospectus and other related matters as the
     Representatives may reasonably require, and the Company shall have
     furnished to such counsel such documents as they reasonably request for the
     purpose of enabling them to pass upon such matters.

         (g) At the time of execution of this Agreement, the Representatives
     shall have received from Ernst & Young LLP a letter, in form and substance
     satisfactory to the Representatives, addressed to the Underwriters and
     dated the date hereof (i) confirming that they are independent public
     accountants within the meaning of the Securities Act and are in compliance
     with the applicable requirements relating to the qualification of
     accountants under Rule 2-01 of Regulation S-X of the Commission, (ii)
     stating, as of the date hereof (or, with respect to matters involving
     changes or developments since the respective dates as of which specified
     financial information is given in the Prospectus, as of a date not more
     than five days prior to the date hereof), the conclusions and findings of
     such firm with respect to the financial information and other matters
     ordinarily covered by accountants' "comfort letters" to underwriters in
     connection with registered public offerings.

         (h) With respect to the letter of Ernst & Young LLP referred to in the
     preceding paragraph and delivered to the Representatives concurrently with
     the execution of this Agreement (the "initial letter"), the Company shall
     have furnished to the Representatives a letter (the "bring-down letter") of
     such accountants, addressed to the Underwriters and dated such Delivery
     Date (i) confirming that they are independent public accountants within the
     meaning of the Securities Act and are in compliance with the applicable
     requirements relating to the qualification of accountants under Rule 2-01
     of Regulation S-X of the Commission, (ii) stating, as of the date of the
     bring-down letter (or, with respect to matters involving changes or
     developments since the respective dates as of which specified financial
     information is given in the Prospectus, as of a date not more than five
     days prior to the date of the bring-down letter), the conclusions and
     findings of such firm with respect to the

                                      -20-





     financial information and other matters covered by the initial letter
     and (iii) confirming in all material respects the conclusions and findings
     set forth in the initial letter.

         (i) The Company shall have furnished to the Representatives a
     certificate, dated such Delivery Date, of its Chairman of the Board, its
     President or a Vice President and its chief financial officer stating that:

         (i) The representations, warranties and agreements of the Company in
     Section 1 are true and correct as of such Delivery Date; the Company has
     complied with all its agreements contained herein; and the conditions set
     forth in Sections 9(a) and 9(k) have been fulfilled; and

         (ii) They have carefully examined the Registration Statement and the
     Prospectus and, in their opinion (A) as of the Effective Date, the
     Registration Statement and Prospectus did not include any untrue statement
     of a material fact and did not omit to state a material fact required to be
     stated therein or necessary to make the statements therein not misleading,
     and (B) since the Effective Date no event has occurred which should have
     been set forth in a supplement or amendment to the Registration Statement
     or the Prospectus.

         (j) Each Selling Stockholder (or the Custodian or one or more
     attorneys-in-fact on behalf of the Selling Stockholders) shall have
     furnished to the Representatives on the Delivery Date a certificate, dated
     such Delivery Date, signed by, or on behalf of, the Selling Stockholder (or
     the Custodian or one or more attorneys-in-fact) stating that the
     representations, warranties and agreements of the Selling Stockholder
     contained herein are true and correct as of such Delivery Date and that the
     Selling Stockholder has complied with all agreements contained herein to be
     performed by the Selling Stockholder at or prior to such Delivery Date.

         (k) (i) Neither the Company nor any of its subsidiaries shall have
     sustained since the date of the latest audited financial statements
     included in the Prospectus any loss or interference with its business from
     fire, explosion, flood or other calamity, whether or not covered by
     insurance, or from any labor dispute or court or governmental action, order
     or decree, otherwise than as set forth or contemplated in the Prospectus or
     (ii) since such date there shall not have been any change in the capital
     stock or long-term debt of the Company or any of its subsidiaries or any
     change, or any development involving a prospective change, in or affecting
     the general affairs, management, financial position, stockholders' equity
     or results of operations of the Company and its subsidiaries, otherwise
     than as set forth or contemplated in the Prospectus, the effect of which,
     in any such case described in clause (i) or (ii), is, in the judgment of
     the Representatives, so material and adverse as to make it impracticable or
     inadvisable to proceed with the public offering or the delivery of the
     Stock being delivered on such Delivery Date on the terms and in the manner
     contemplated in the Prospectus.

                                      -21-




         (l) Subsequent to the execution and delivery of this Agreement there
     shall not have occurred any of the following: (i) trading in securities
     generally on the New York Stock Exchange or the American Stock Exchange or
     in the over-the-counter market, or trading in any securities of the Company
     on any exchange or in the over-the-counter market, shall have been
     suspended or minimum prices shall have been established on any such
     exchange or such market by the Commission, by such exchange or by any other
     regulatory body or governmental authority having jurisdiction, (ii) a
     banking moratorium shall have been declared by Federal or state
     authorities, (iii) the United States shall have become engaged in
     hostilities, there shall have been an escalation in hostilities involving
     the United States or there shall have been a declaration of a national
     emergency or war by the United States or (iv) there shall have occurred
     such a material adverse change in general economic, political or financial
     conditions (or the effect of international conditions on the financial
     markets in the United States shall be such) as to make it, in the judgment
     of a majority in interest of the several Underwriters, impracticable or
     inadvisable to proceed with the public offering or delivery of the Stock
     being delivered on such Delivery Date on the terms and in the manner
     contemplated in the Prospectus.

         (m) The Nasdaq National Market shall have approved the Stock for
     inclusion, subject only to official notice of issuance and evidence of
     satisfactory distribution.

         (n) You shall have been furnished such additional documents and
     certificates as you or counsel for the Underwriters may reasonably request
     relating to this Agreement and the transactions contemplated hereby.

     All opinions, letters, evidence and certificates mentioned above or
elsewhere in this Agreement shall be deemed to be in compliance with the
provisions hereof only if they are in form and substance reasonably satisfactory
to counsel for the Underwriters.

         10. Indemnification and Contribution.

         (a) The Company shall indemnify and hold harmless each Underwriter, its
     officers and employees and each person, if any, who controls any
     Underwriter within the meaning of the Securities Act, from and against any
     loss, claim, damage or liability, joint or several, or any action in
     respect thereof (including, but not limited to, any loss, claim, damage,
     liability or action relating to purchases and sales of Stock), to which
     that Underwriter, officer, employee or controlling person may become
     subject, under the Securities Act or otherwise, insofar as such loss,
     claim, damage, liability or action arises out of, or is based upon, (i) any
     untrue statement or alleged untrue statement of a material fact contained
     (A) in any Preliminary Prospectus, the Registration Statement or the
     Prospectus or in any amendment or supplement thereto or (B) in any blue sky
     application or other document prepared or executed by the Company (or based
     upon any written information furnished by the Company) specifically for the
     purpose of qualifying any or all of the Stock under the securities laws of
     any state or other jurisdiction (any such application, document

                                      -22-




     or information being hereinafter called a "Blue Sky Application"), (ii)
     the omission or alleged omission to state in any Preliminary Prospectus,
     the Registration Statement or the Prospectus, or in any amendment or
     supplement thereto, or in any Blue Sky Application any material fact
     required to be stated therein or necessary to make the statements therein
     not misleading or (iii) any act or failure to act or any alleged act or
     failure to act by any Underwriter in connection with, or relating in any
     manner to, the Stock or the offering contemplated hereby, and which is
     included as part of or referred to in any loss, claim, damage, liability or
     action arising out of or based upon matters covered by clause (i) or (ii)
     above (provided that the Company shall not be liable under this clause
     (iii) to the extent that it is determined in a final judgment by a court of
     competent jurisdiction that such loss, claim, damage, liability or action
     resulted directly from any such acts or failures to act undertaken or
     omitted to be taken by such Underwriter through its gross negligence or
     willful misconduct), and shall reimburse each Underwriter and each such
     officer, employee or controlling person promptly upon demand for any legal
     or other expenses reasonably incurred by that Underwriter, officer,
     employee or controlling person in connection with investigating or
     defending or preparing to defend against any such loss, claim, damage,
     liability or action as such expenses are incurred; provided, however, that
     the Company shall not be liable in any such case to the extent that any
     such loss, claim, damage, liability or action arises out of, or is based
     upon, any untrue statement or alleged untrue statement or omission or
     alleged omission made in any Preliminary Prospectus, the Registration
     Statement or the Prospectus, or in any such amendment or supplement, or in
     any Blue Sky Application, in reliance upon and in conformity with written
     information concerning such Underwriter furnished to the Company through
     the Representatives by or on behalf of any Underwriter specifically for
     inclusion therein, which information consists solely of the information
     specified in Section 10(f). The foregoing indemnity agreement is in
     addition to any liability which the Company may otherwise have to any
     Underwriter or to any officer, employee or controlling person of that
     Underwriter.

         (b) The Selling Stockholders, severally in proportion to the number of
     shares of Stock to be sold by each of them hereunder, shall indemnify and
     hold harmless each Underwriter, its officers and employees, and each
     person, if any, who controls any Underwriter within the meaning of the
     Securities Act, from and against any loss, claim, damage or liability,
     joint or several, or any action in respect thereof (including, but not
     limited to, any loss, claim, damage, liability or action relating to
     purchases and sales of Stock), to which that Underwriter, officer, employee
     or controlling person may become subject, under the Securities Act or
     otherwise, insofar as such loss, claim, damage, liability or action arises
     out of, or is based upon, (i) any untrue statement or alleged untrue
     statement of a material fact contained in any Preliminary Prospectus, the
     Registration Statement or the Prospectus or in any amendment or supplement
     thereto or (ii) the omission or alleged omission to state in any
     Preliminary Prospectus, Registration Statement or the Prospectus, or in any
     amendment or supplement thereto, any material fact required to be stated
     therein or necessary to make the statements therein not misleading, and
     shall reimburse each Underwriter, its officers and employees and each such
     controlling person for any legal or

                                      -23-




     other expenses reasonably incurred by that Underwriter, its officers
     and employees or controlling person in connection with investigating or
     defending or preparing to defend against any such loss, claim, damage,
     liability or action as such expenses are incurred; provided, however, that
     the Selling Stockholders shall not be liable in any such case to the extent
     that any such loss, claim, damage, liability or action arises out of, or is
     based upon, any untrue statement or alleged untrue statement or omission or
     alleged omission made in any Preliminary Prospectus, the Registration
     Statement or the Prospectus or in any such amendment or supplement in
     reliance upon and in conformity with written information concerning such
     Underwriter furnished to the Company through the Representatives by or on
     behalf of any Underwriter specifically for inclusion therein which
     information consists solely of the information specified in Section 10(f).
     Notwithstanding the foregoing sentence, the aggregate liability of any
     Selling Stockholder pursuant to the provisions of this paragraph shall be
     limited to an amount equal to the aggregate purchase price, less
     underwriting discounts and commissions, received by such Selling
     Stockholder from the sale of such Selling Stockholder's Stock hereunder.
     The foregoing indemnity agreement is in addition to any liability which the
     Selling Stockholders may otherwise have to any Underwriter or any officer,
     employee or controlling person of that Underwriter.

         (c) Each Underwriter, severally and not jointly, shall indemnify and
     hold harmless the Company, its officers and employees, each of its
     directors (including any person who, with his or her consent, is named in
     the Registration Statement as about to become a director of the Company),
     and each person, if any, who controls the Company within the meaning of the
     Securities Act, from and against any loss, claim, damage or liability,
     joint or several, or any action in respect thereof, to which the Company or
     any such director, officer or controlling person may become subject, under
     the Securities Act or otherwise, insofar as such loss, claim, damage,
     liability or action arises out of, or is based upon, (i) any untrue
     statement or alleged untrue statement of a material fact contained (A) in
     any Preliminary Prospectus, the Registration Statement or the Prospectus or
     in any amendment or supplement thereto, or (B) in any Blue Sky Application
     or (ii) the omission or alleged omission to state in any Preliminary
     Prospectus, the Registration Statement or the Prospectus, or in any
     amendment or supplement thereto, or in any Blue Sky Application any
     material fact required to be stated therein or necessary to make the
     statements therein not misleading, but in each case only to the extent that
     the untrue statement or alleged untrue statement or omission or alleged
     omission was made in reliance upon and in conformity with written
     information concerning such Underwriter furnished to the Company through
     the Representatives by or on behalf of that Underwriter specifically for
     inclusion therein, and shall reimburse the Company and any such director,
     officer or controlling person for any legal or other expenses reasonably
     incurred by the Company or any such director, officer or controlling person
     in connection with investigating or defending or preparing to defend
     against any such loss, claim, damage, liability or action as such expenses
     are incurred. The foregoing indemnity agreement is in addition to any
     liability which any Underwriter may otherwise have to the Company or any
     such director, officer, employee or controlling person.

                                      -24-




         (d) Promptly after receipt by an indemnified party under this Section
     10 of notice of any claim or the commencement of any action, the
     indemnified party shall, if a claim in respect thereof is to be made
     against the indemnifying party under this Section 10, notify the
     indemnifying party in writing of the claim or the commencement of that
     action; provided, however, that the failure to notify the indemnifying
     party shall not relieve it from any liability which it may have under this
     Section 10 except to the extent it has been materially prejudiced by such
     failure and, provided further, that the failure to notify the indemnifying
     party shall not relieve it from any liability which it may have to an
     indemnified party otherwise than under this Section 10. If any such claim
     or action shall be brought against an indemnified party, and it shall
     notify the indemnifying party thereof, the indemnifying party shall be
     entitled to participate therein and, to the extent that it wishes, jointly
     with any other similarly notified indemnifying party, to assume the defense
     thereof with counsel reasonably satisfactory to the indemnified party.
     After notice from the indemnifying party to the indemnified party of its
     election to assume the defense of such claim or action, the indemnifying
     party shall not be liable to the indemnified party under this Section 10
     for any legal or other expenses subsequently incurred by the indemnified
     party in connection with the defense thereof other than reasonable costs of
     investigation; provided, however, that the Representatives shall have the
     right to employ counsel to represent jointly the Representatives and those
     other Underwriters and their respective officers, employees and controlling
     persons who may be subject to liability arising out of any claim in respect
     of which indemnity may be sought by the Underwriters against the Company or
     any Selling Stockholder under this Section 10 if, in the reasonable
     judgment of the Representatives, it is advisable for the Representatives
     and those Underwriters, officers, employees and controlling persons to be
     jointly represented by separate counsel because of actual differing
     interests among the parties, and in that event the fees and expenses of
     such separate counsel shall be paid by the Company or Selling Stockholders.
     No indemnifying party shall (i) without the prior written consent of the
     indemnified parties (which consent shall not be unreasonably withheld),
     settle or compromise or consent to the entry of any judgment with respect
     to any pending or threatened claim, action, suit or proceeding in respect
     of which indemnification or contribution may be sought hereunder (whether
     or not the indemnified parties are actual or potential parties to such
     claim or action) unless, such settlement, compromise or consent includes an
     unconditional release of each indemnified party from all liability arising
     out of such claim, action, suit or proceeding, or (ii) be liable for any
     settlement of any such action effected without its written consent (which
     consent shall not be unreasonably withheld), but if settled with the
     consent of the indemnifying party or if there be a final judgment of the
     plaintiff in any such action, the indemnifying party agrees to indemnify
     and hold harmless any indemnified party from and against any loss or
     liability by reason of such settlement or judgment. 

         (e) If the indemnification provided for in this Section 10 shall for
     any reason be unavailable to or insufficient to hold harmless an
     indemnified party under Section 10(a), 10(b) or 10(c) in respect of any
     loss, claim, damage or liability, or any action in respect thereof,
     referred to therein, then each indemnifying party shall, in lieu of
     indemnifying such

                                      -25-




     indemnified party, contribute to the amount paid or payable by such
     indemnified party as a result of such loss, claim, damage or liability, or
     action in respect thereof, (i) in such proportion as shall be appropriate
     to reflect the relative benefits received by the Company and the Selling
     Stockholders on the one hand and the Underwriters on the other from the
     offering of the Stock or (ii) if the allocation provided by clause (i)
     above is not permitted by applicable law, in such proportion as is
     appropriate to reflect not only the relative benefits referred to in clause
     (i) above but also the relative fault of the Company and the Selling
     Stockholders on the one hand and the Underwriters on the other with respect
     to the statements or omissions which resulted in such loss, claim, damage
     or liability, or action in respect thereof, as well as any other relevant
     equitable considerations; provided that no Selling Stockholder shall be
     required to contribute in excess of the amount of the purchase price for
     the sale of Stock of such Selling Stockholder less underwriting discounts
     and commissions. The relative benefits received by the Company and the
     Selling Stockholders on the one hand and the Underwriters on the other with
     respect to such offering shall be deemed to be in the same proportion as
     the total net proceeds from the offering of the Stock purchased under this
     Agreement (before deducting expenses) received by the Company and the
     Selling Stockholders, on the one hand, and the total underwriting discounts
     and commissions received by the Underwriters with respect to the shares of
     the Stock purchased under this Agreement, on the other hand, bear to the
     total gross proceeds from the offering of the shares of the Stock under
     this Agreement, in each case as set forth in the table on the cover page of
     the Prospectus. The relative fault shall be determined by reference to
     whether the untrue or alleged untrue statement of a material fact or
     omission or alleged omission to state a material fact relates to
     information supplied by the Company, the Selling Stockholders or the
     Underwriters, the intent of the parties and their relative knowledge,
     access to information and opportunity to correct or prevent such statement
     or omission. The Company, the Selling Stockholders and the Underwriters
     agree that it would not be just and equitable if contributions pursuant to
     this Section 10(e) were to be 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 into account the equitable
     considerations referred to herein. The amount paid or payable by an
     indemnified party as a result of the loss, claim, damage or liability, or
     action in respect thereof, referred to above in this Section shall be
     deemed to include, for purposes of this Section 10(e), any legal or other
     expenses reasonably incurred by such indemnified party in connection with
     investigating or defending any such action or claim. Notwithstanding the
     provisions of this Section 10(e), no Underwriter shall be required to
     contribute any amount in excess of the amount by which the total price at
     which the Stock underwritten by it and distributed to the public was
     offered to the public exceeds the amount of any damages which such
     Underwriter has otherwise paid or become liable to pay by reason of any
     untrue or alleged untrue statement or omission or alleged omission. No
     person guilty of fraudulent misrepresentation (within the meaning of
     Section 11(f) of the Securities Act) shall be entitled to contribution from
     any person who was not guilty of such fraudulent misrepresentation. The
     Underwriters' obligations to contribute as provided in this Section 10(e)
     are several in proportion to their respective underwriting obligations and
     not joint.

                                      -26-




         (f) The Underwriters severally confirm and the Company acknowledges
     that the statements with respect to the public offering of the Stock by the
     Underwriters set forth on the cover page of, the legend concerning
     over-allotments on the inside front cover page of and the concession and
     reallowance figures appearing under the caption "Underwriting" in, the
     Prospectus are correct and constitute the only information concerning such
     Underwriters furnished in writing to the Company by or on behalf of the
     Underwriters specifically for inclusion in the Registration Statement and
     the Prospectus.

     11. Defaulting Underwriters. If, on either Delivery Date, any Underwriter
defaults in the performance of its obligations under this Agreement, the
remaining non-defaulting Underwriters shall be obligated to purchase the Stock
which the defaulting Underwriter agreed but failed to purchase on such Delivery
Date in the respective proportions which the number of shares of the Firm Stock
set opposite the name of each remaining non-defaulting Underwriter in Schedule 1
hereto bears to the total number of shares of the Firm Stock set opposite the
names of all the remaining nondefaulting Underwriters in Schedule 1 hereto;
provided, however, that the remaining nondefaulting Underwriters shall not be
obligated to purchase any of the Stock on such Delivery Date if the total number
of shares of the Stock which the defaulting Underwriter or Underwriters agreed
but failed to purchase on such date exceeds 9.09% of the total number of shares
of the Stock to be purchased on such Delivery Date, and any remaining
non-defaulting Underwriter shall not be obligated to purchase more than 110% of
the number of shares of the Stock which it agreed to purchase on such Delivery
Date pursuant to the terms of Section 3. If the foregoing maximums are exceeded,
the remaining non-defaulting Underwriters, or those other underwriters
satisfactory to the Representatives who so agree, shall have the right, but
shall not be obligated, to purchase, in such proportion as may be agreed upon
among them, all the Stock to be purchased on such Delivery Date. If the
remaining Underwriters or other underwriters satisfactory to the Representatives
do not elect to purchase the shares which the defaulting Underwriter or
Underwriters agreed but failed to purchase on such Delivery Date, this Agreement
(or, with respect to the Second Delivery Date, the obligation of the
Underwriters to purchase, and of the Company to sell, the Option Stock) shall
terminate without liability on the part of any non-defaulting Underwriter or the
Company or the Selling Stockholders, except that the Company will continue to be
liable for the payment of expenses to the extent set forth in Sections 8 and 13.
As used in this Agreement, the term "Underwriter" includes, for all purposes of
this Agreement unless the context requires otherwise, any party not listed in
Schedule 1 hereto who, pursuant to this Section 11, purchases Firm Stock which a
defaulting Underwriter agreed but failed to purchase.

     Nothing contained herein shall relieve a defaulting Underwriter of any
liability it may have to the Company and the Selling Stockholders for damages
caused by its default. If other underwriters are obligated or agree to purchase
the Stock of a defaulting or withdrawing Underwriter, either the Representatives
or the Company may postpone the Delivery Date for up to seven full business days
in order to effect any changes that in the opinion of counsel for the Company or
counsel for the Underwriters may be necessary in the Registration Statement, the
Prospectus or in any other document or arrangement.

     12. Termination. The obligations of the Underwriters hereunder may be
terminated by the Representatives by notice given to and received by the Company
and the Selling Stockholders prior to delivery of and payment for the Firm Stock
if, prior to that time, any of the events described in Sections 9(k) or 9(l),
shall have occurred or if the Underwriters shall decline to purchase the Stock
for any reason permitted under this Agreement.

     13. Reimbursement of Underwriters' Expenses. If (a) the Company or any
Selling Stockholder shall fail to tender the Stock for delivery to the
Underwriters by reason of any failure, refusal or inability on the part of the
Company or any Selling Stockholder(s) to perform any agreement on its part to be
performed, or because any other condition of the Underwriters' obligations
hereunder required to be fulfilled by the Company or the Selling Stockholder(s)
is not fulfilled, the Company and the Selling Stockholder(s) will reimburse the
Underwriters for all reasonable out-of-pocket expenses (including fees and
disbursements of counsel) incurred by the Underwriters in connection with this
Agreement and the proposed purchase of the Stock, and upon demand the Company
and the Selling Stockholder(s) shall pay the full amount thereof to the
Representative(s). If this Agreement is terminated pursuant to Section 11 by
reason of the default of one or more Underwriters, neither the Company nor any
Selling Stockholder shall be obligated to reimburse any defaulting Underwriter
on account of those expenses.

     14. Notices, etc. All statements, requests, notices and agreements
hereunder shall be in writing, and:
