Purchasers as follows:

          (a)  To advise the Initial Purchasers promptly and, if requested by
the Initial Purchasers, confirm such advice in writing, (i) of the issuance by
any state securities commission of any stop order suspending the qualification
or exemption from qualification of any Shares for offering or sale in any
jurisdiction designated by the Initial Purchasers pursuant to Section 5(e)
hereof, or the initiation of any proceeding by any state securities commission
or any other federal or state regulatory authority for such purpose and (ii) of
the happening of any event during the period referred to in Section 5(c) below
that makes any statement of a material fact made in the Preliminary Offering
Memorandum or the Offering Memorandum untrue or that requires any additions to
or changes in the Preliminary Offering Memorandum or the Offering Memorandum in
order to make the statements therein not misleading. The Company shall use its
best efforts to prevent the issuance of any stop order or order suspending the

                                       3
<PAGE>
 
qualification or exemption of any Shares under any state securities or Blue Sky
laws and, if at any time any state securities commission or other federal or
state regulatory authority shall issue an order suspending the qualification or
exemption of any Shares 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 as many copies of the Preliminary Offering
Memorandum and the Offering Memorandum, any documents incorporated by reference
therein, and any amendments or supplements thereto, as the Initial Purchasers
may reasonably request for the time period specified in Section 5(c). Subject to
the Initial Purchasers' compliance with its representations and warranties and
agreements set forth in Section 7 hereof, the Company consents to the use of the
Preliminary Offering Memorandum and the Offering Memorandum, any documents
incorporated by reference therein, and any amendments and supplements thereto
required pursuant hereto, by the Initial Purchasers in connection with Exempt
Resales.

          (c)  During such period as in the opinion of counsel for the Initial
Purchasers an Offering Memorandum is required by law to be delivered in
connection with Exempt Resales by the Initial Purchasers (i) not to make any
amendment or supplement to the Offering Memorandum of which the Initial
Purchasers shall not previously have been advised or to which the Initial
Purchasers shall reasonably object after being so advised and (ii) to prepare
promptly upon the Initial Purchasers' reasonable request, any amendment or
supplement to the Offering Memorandum which may be necessary or advisable in
connection with such Exempt Resales.

          (d)  If, during the period referred to in Section 5(c) above, any
event shall occur or condition shall exist as a result of which, in the opinion
of counsel to the Initial Purchasers, it becomes necessary to amend or
supplement the 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, not misleading, or if, in the opinion of counsel for the
Initial Purchasers, it is necessary to amend or supplement the Offering
Memorandum to comply with any applicable law, forthwith to prepare an
appropriate amendment or supplement to such Offering 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, and to furnish to the Initial
Purchasers and such other persons as the Initial Purchasers may designate such
number of copies thereof as the Initial Purchasers may reasonably request.

          (e)  Prior to the sale of all Shares pursuant to Exempt Resales as
contemplated hereby, to cooperate with the Initial Purchasers and counsel to the
Initial Purchasers in connection with the registration or qualification of the
Shares for offer and sale to the Initial Purchasers and pursuant to Exempt
Resales under the securities or Blue Sky laws of such jurisdictions as the
Initial Purchasers may request and to continue such registration or
qualification in effect so long as required for Exempt Resales and to file such
consents to service of process or other documents as may be necessary in order
to effect such registration or qualification; provided, however, that the
Company shall not be required in connection therewith to qualify as a foreign
corporation in any jurisdiction in which it is not now so qualified or to take
any action that would subject it to general consent to service of process or
taxation other than as to matters and transactions relating to the Preliminary
Offering Memorandum, the Offering Memorandum or Exempt Resales, in any
jurisdiction in which it is not now so subject.

          (t)  Neither the Company nor any of its subsidiaries nor any agent

contemplated hereby, including, but not limited to, articles, notices or other
communications published in any newspaper, magazine, or similar medium or

"Intellectual Property"), presently employed by them in connection with the busi
nesses now operated by them, and neither the Company nor any subsidiary has
received any notice of infringement of or conflict with asserted rights of
others with respect to the foregoing except as could not, singly or in the
aggregate, reasonably be expected to have a Material Adverse Effect.  The use of
such Intellectual Property in connection with the business and operations of the
Company and the subsidiaries does not infringe on the rights of any person.

several Initial Purchasers in the requisite quantity and on a timely basis to
permit proper delivery on or prior to the Closing Date) to the person asserting
any losses, claims, damages, liabilities or judgments caused by any untrue
statement or alleged untrue statement of a material fact contained in such
Preliminary Offering Memorandum, or caused by any omission or alleged omission
to state therein a material fact required to be stated therein or necessary to
make the statements therein not misleading, if such material misstatement or
omission or alleged material misstatement or omission was cured in the Offering
Memorandum, as so amended or supplemented.

          (b)  Each Initial Purchaser, severally and not jointly, agrees to
indemnify and hold harmless the Company and its directors and officers and each
person, if any, who controls (within the meaning of Section 15 of the Act or
Section 20 of the Exchange Act) the Company to the same extent as the foregoing
indemnity from the Company to the Initial Purchasers but only with reference to
Initial Purchaser Information.

          (c)  In case any action shall be commenced involving any person in
respect of which indemnity may be sought pursuant to Section 8(a) or 8(b) (the
                                                                              
"INDEMNIFIED PARTY"), the indemnified party shall promptly notify the person
------------ -----                                                          
against whom such indemnity may be sought (the "INDEMNIFYING PARTY") in writing
                                                ------------ -----             
and the indemnifying party shall assume the defense of such action, including
the employment of counsel reasonably satisfactory to the indemnified party and
the payment of all fees and expenses of such counsel, as incurred (except that
in the case of any action in respect of which indemnity may be sought pursuant
to both Sections 8(a) and 8(b), the Initial Purchasers shall not be required to
assume the defense of such action pursuant to this Section 8(c), but may employ
separate counsel and participate in the defense thereof, but the fees
and expenses of such counsel, except as provided below, shall be at the expense
of the Initial Purchasers).  Any indemnified party shall have the right to
employ separate counsel in any such action and participate in the defense
thereof, but the fees and expenses of such counsel shall be at the expense of
the indemnified party unless (i) the employment of such counsel shall have been
specifically authorized in writing by the indemnifying party, (ii) the
indemnifying party shall have failed to assume the defense of such action or
employ counsel reasonably satisfactory to the indemnified party or (iii) the
named parties to any such action (including any impleaded parties) include both
the indemnified party and the indemnifying party, and the indemnified party
shall have been advised by such counsel that there may be one or more legal
defenses available to it which are different from or additional to those
available to the indemnifying party (in which case the indemnifying party shall
not have the right to assume the defense of such action on behalf of the
indemnified party).  In any such case, the indemnifying party shall not, in
connection with any one action or separate but substantially similar or related
actions in the same jurisdiction arising out of the same general allegations or
circumstances, be liable for the fees and expenses of more than one separate
firm of attorneys (in addition to any local counsel) for all indemnified parties
and all such fees and expenses shall be reimbursed as they are incurred.  Such
firm shall be designated in writing by Donaldson, Lufkin & Jenrette Securities
Corporation, in the case of the parties indemnified pursuant to Section 8(a),
and by the Company, in the case of parties indemnified pursuant to Section 8(b).
The indemnifying party shall indemnify and hold harmless the indemnified party
from and against any and all losses, claims, damages, liabilities and judgments
by reason of any settlement of any action (i) effected with its written consent
or (ii) effected without its written consent if the settlement is entered into
more than twenty business days after the indemnifying party shall have received
a request from the indemnified party for reimbursement for the fees and expenses
of counsel (in any case where such fees and expenses are at the expense of the
indemnifying party) and, prior to the date of such settlement, the indemnifying
party shall have failed to comply with such reimbursement request.   No
indemnifying party shall, without the prior written consent of the indemnified
party, effect any settlement or compromise of, or consent to the entry of
judgment with respect to, any pending or threatened action in respect of which
the indemnified party is or could have been a party and indemnity or
contribution may be or could have been sought hereunder by the indemnified
party, unless such settlement, compromise or judgment (i) includes an
unconditional release of the indemnified party from all liability on claims that
are or could have been the 

                                      15
<PAGE>
 
subject matter of such action and (ii) does not include a statement as to or an
admission of fault, culpability or a failure to act, by or on behalf of the
indemnified party.

          (d)  To the extent the indemnification provided for in this Section 8
is unavailable to an indemnified party or insufficient in respect of any losses,
claims, damages, liabilities or judgments referred to therein, then each
indemnifying party, in lieu of indemnifying such indemnified party, shall
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages, liabilities and judgments (i) in such
proportion as is appropriate to reflect the relative benefits received by the
Company, on the one hand, and the Initial Purchasers, on the other hand, from
the offering of the Securities or (ii) if the allocation provided by clause
8(d)(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
8(d)(i) above but also the relative fault of the Company, on the one hand, and
the Initial Purchasers, on the other hand, in connection with the statements or
omissions which resulted in such losses, claims, damages, liabilities or
judgments, as well as any other relevant equitable considerations.  The relative
benefits received by the Company, on the one hand, and the Initial Purchasers,
on the other hand, shall be deemed to be in the same proportion as the total net
proceeds from the offering of the Securities (after Initial Purchaser's
discounts or commissions, but before deducting expenses) received by the
Company, and the total discounts and commissions received by the Initial
Purchasers bear to the total price to investors of the Securities, in each case
as set forth in the table on the cover page of the Offering Memorandum. The
relative fault of the Company, on the one hand, and the Initial Purchasers, on
the other hand, 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, on the one hand, or the Initial Purchasers, on the other hand, 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 8(d) were determined by
pro rata allocation (even if the Initial Purchasers 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 in the immediately preceding
paragraph.  The amount paid or payable by an indemnified party as a result of
the losses, claims, damages, liabilities or judgments referred to in the
immediately preceding paragraph shall be deemed to include, subject to the
limitations set forth above, any legal or other expenses incurred by such
indemnified party in connection with investigating or defending any matter,
including any action, that could have given rise to such losses, claims,
damages, liabilities or judgments.  Notwithstanding the provisions of this
Section 8, the Initial Purchasers shall not be required to contribute any amount
in excess of the amount by which the total discounts and commissions received by
such Initial Purchasers exceeds the amount of any damages which the Initial
Purchasers have otherwise been required to pay by reason of such 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 Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.  The Initial Purchasers' obligations to contribute
pursuant to this Section 8(d) are several in proportion to the respective number
of Shares purchased by each of the Initial Purchasers hereunder, and not joint.

                                      16

          (e)  The remedies provided for in this Section 8 are not exclusive and
shall not limit any rights or remedies which may otherwise be available to any
indemnified party at law or in equity.

          9.   CONDITIONS OF INITIAL PURCHASERS' OBLIGATIONS.  The obligations
               ---------------------------------------------                  
of the Initial Purchasers to purchase the Shares under this Agreement on the
Closing Date are subject to the satisfaction of each of the following
conditions.

          (a)  All the representations and warranties of the Company contained
in this Agreement shall be true and correct on the Closing Date with the same
force and effect as if made on and as of the Closing Date.

          (b)  On or after the date hereof, (i) there shall not have occurred
any downgrading, suspension or withdrawal of, nor shall any notice have been
given of any potential or intended downgrading, suspension or withdrawal of, or
of any review (or of any potential or intended review) for a possible change
that does not indicate the direction of the possible change in, any rating of
the Company or any securities of the Company (including, without limitation, the
placing of any of the foregoing ratings on credit watch with negative or
developing implications or under review with an uncertain direction) by any
"nationally recognized statistical rating organization" as such term is defined
for purposes of Rule 436(g)(2) under the Act and (ii) there shall not have
occurred any change, nor shall any notice have been given of any potential or
intended change, in the outlook for any rating of the Company or any securities
of the Company by any such rating organization.

          (c)  Since the respective dates as of which information is given in
the Offering Memorandum other than as set forth in the Offering Memorandum
(exclusive of any amendments or supplements thereto subsequent to the date of
this Agreement), (i) there shall not have occurred any change or any development
involving a prospective change in the condition, financial or otherwise, or the
earnings, business, management or operations of the Company and its
subsidiaries, taken as a whole, (ii) there shall not have been any change or any
development involving a prospective change in the capital stock or in the long-
term debt of the Company or any of its subsidiaries and (iii) neither the
Company nor any of its subsidiaries shall have incurred any liability or
obligation, direct or contingent, the effect of which, in any such case
described in clause 9(c)(i), 9(c)(ii) or 9(c)(iii), in your judgment, is
material and adverse and, in your judgment, makes it impracticable to market the
Shares on the terms and in the manner contemplated in the Offering Memorandum.

          (d)  The Initial Purchasers shall have received on the Closing Date a
certificate, dated the Closing Date, signed by the Chief Financial Officer and
the Secretary of the Company, confirming the matters set forth in Sections 6(v),
9(a) and 9(b) and stating that the Company has complied with all the agreements
and satisfied all of the conditions herein contained and required to be complied
with or satisfied on or prior to the Closing Date.

          (e)  The Initial Purchasers shall have received on the Closing Date an
opinion, dated the Closing Date, of Piper & Marbury L.L.P., counsel for the
Company, to the effect that:

the State of Delaware and has the requisite power and authority to carry on its
business as described in the Offering Memorandum and to own, lease and operate
its properties.

                (ii)  each of the Company and its subsidiaries identified in
Schedule D hereto is duly qualified and is in good standing as a foreign entity
authorized to do business in each jurisdiction in which the nature of its
business or its ownership or leasing of property requires such qualification,
except where the failure to be so qualified would not have a Material Adverse
Effect;

Company have been duly authorized and validly issued and are fully paid, non-
assessable and not subject to any preemptive or similar rights;

                (iv)  all of the outstanding shares of capital stock of, or
other ownership interests in, each subsidiary have been duly authorized and
validly issued and are fully paid and nonassessable, and, to the best of such
counsel's knowledge after due inquiry, other than (i) the ownership by an
unaffiliated third-party of 549 shares of OCI Common Stock and (ii) except for
the information set forth in Schedule C hereto, are owned, directly or
indirectly, by the Company free and clear of any Lien; and, to the best of such
counsel's knowledge after due inquiry, there are no outstanding subscriptions,
rights, warrants, options, calls, convertible or exchangeable securities,
commitments of sale, or Liens related to or entitling any person to purchase or
other wise to acquire any shares of the capital stock of, or other ownership
interest in, any subsidiary;

                (v)  the Preferred Stock, and the deposit of the Preferred Stock
by the Company in accordance with the Deposit Agreement, have been duly and

the Shares have been duly authorized and reserved for issuance upon such
conversion and, when issued upon such conversion, will be validly issued, fully
paid and nonassessable, will conform with the description thereof contained in

                (vii)  assuming due authorization, execution and delivery of the
Deposit Agreement by the Depositary, each Share, upon delivery of the Depositary

outstanding, fully paid and nonassessable shares of Preferred Stock; assuming
due execution and delivery of the Depositary Receipts by the Depositary pursuant
to the Deposit

Agreement and upon payment for the Depositary Shares and delivery of the
Depositary Receipts in accordance with this Agreement, the Depositary Receipts
will entitle the holders thereof to the benefits provided therein and in the
Deposit Agreement;

                (viii)  this Agreement has been duly authorized, executed and

                (ix)  Each of the Registration Rights Agreement, the Deposit

Environment", "Plan of Distribution" and "Certain United States Federal Income
Tax Consequences" in the Offering Memorandum, insofar as such statements
constitute a summary of the legal matters, documents or proceedings referred to
therein, fairly present in all material respects such legal matters, documents
and proceedings;

                (xi)  to the best of such counsel's knowledge, after due
inquiry, neither the Company nor any of its subsidiaries is (A) in violation of
its respective charter (or in the case of limited liability company, certificate
of formation) or by-laws or (B) in default in the performance of any obligation,
agreement, covenant or condition contained in any indenture, loan agreement,

counsel in writing as material to the Company and its subsidiaries, taken as a
whole, to which the Company or any of its subsidiaries is a party or by which
the Company or any of its subsidiaries or their respective property is bound;

                (xii)  the execution, delivery and performance of this Agreement
and the other Operative Documents by the Company, the compliance by the Company
with all provisions hereof and thereof and the consummation of the transactions
contemplated hereby and thereby will not (i) require any consent, approval,

instrument to which the Company or any of its subsidiaries is a party or by
which the Company or any of its subsidiaries or their respective property is
bound, (v) result in the termination, suspension or revocation of any
Authorization of the Company or any of its subsidiaries or result in any other
impairment of the rights of the holder of any such Authorization, or 
(vi) require notice to or approval of the FCC, any Applicable PUC or any court
or any governmental body or agency having jurisdiction over the Company, any of
its subsidiaries or their respective property;

                (xiii)  after due inquiry, such counsel does not know of any
legal or governmental proceedings pending or threatened to which the Company or
any of its subsidiaries is or could be a party or to which any of their
respective property is or could be subject, which might result, singly or in the
aggregate, in a Material Adverse Effect;

                (xiv)  to the best of such counsel's knowledge, neither the
Company nor any of its subsidiaries has violated any Environmental Law, any
provisions of ERISA, or any provisions of the Foreign Corrupt Practices Act or
the rules and regulations promulgated thereunder, except for such violations
which, singly or in the aggregate, would not have a Material Adverse Effect;

                (xv)  each of the Company and its subsidiaries has such
Authorizations of, and has made all filings with and notices to, all
governmental or regulatory authorities and self-regulatory organizations and all
courts and other tribunals, including without limitation, the FCC and Applicable
PUCs, as are necessary to own, lease, license and operate its respective
properties and to conduct its business as currently being conducted and as
proposed to be conducted as described in the Offering Memorandum, except where
the failure to have any such Authorization or to make any such filing or notice
would not, singly or in the aggregate, have a Material Adverse Effect. Each such
Authorization is valid and in full force and effect and, to the best of such
counsel's knowledge, each of the Company and its subsidiaries is in compliance
with all the terms and conditions thereof and with the rules and regulations of
the authorities and governing bodies having jurisdiction with respect thereto,
subject to such qualifications as may be set forth in the Offering Memorandum;
and, to the best of such counsel's knowledge, no event has occurred (including
the receipt of any notice from any authority or governing body) which allows or,
after notice or lapse of time or both, would allow, revocation, suspension or
termination of any such Authorization or results or, after notice or lapse of
time or both, would result in any other impairment of the rights of the holder
of any such Authorization, subject to such qualifications as may be set forth in
the Offering Memorandum; and such Authorizations contain no restrictions that
are burdensome to the Company or any of its subsidiaries; except where such
failure to be valid and in full force and effect or to be in compliance, the
occurrence of any such event or the presence of any such restriction would not,
singly or in the aggregate, have a Material Adverse Effect;

                (xvi)  the Company is not and, after giving effect to the
offering and sale of the Shares and the application of the net proceeds thereof
as described in the Offering Memorandum, will not be, an "investment company" as
such term is defined in the Investment Company Act of 1940, as amended;

                (xvii)  to the best of such counsel's knowledge after due
inquiry, there are no contracts, agreements or understandings between the
Company and any person granting such person the right to require the Company to
file a registration statement under the Act with respect

                                      20
<PAGE>
 
to any securities of the Company or to require the Company to include such
securities with the Shares registered pursuant to any Registration Statement,
except for the parties set forth in Schedule E hereto.

                (xviii)  no registration under the Act of the Shares is required
for the sale of the Shares to the Initial Purchasers as contemplated by this
Agreement or for the Exempt Resales assuming that (i) each Initial Purchaser is
a QIB, (ii) the accuracy of, and compliance with, the Initial Purchasers'
representations and agreements contained in Section 7 of this Agreement, (iii)
the accuracy of the representations of the Company set forth in Section 6(y) of
this Agreement;

                (xix)  such counsel has no reason to believe that, as of the
date of the Offering Memorandum or as of the Closing Date, the Offering
Memorandum and any information incorporated by reference therein, as amended or
supplemented, if applicable (except for the financial statements and other
financial data included therein, as to which such counsel need not express any
belief) contains any untrue statement of a material fact or omits to state a
material fact necessary in order to make the statements therein, in the light of
the circumstances under which they were made, not misleading.

          The opinion of Piper & Marbury L.L.P. described in Section 9(e) above
shall be rendered to the Initial Purchasers at the request of the Company and
shall so state therein. In giving such opinion with respect to the matters
covered by Section 9(e), Piper & Marbury L.L.P. may state that their opinion and
belief are based upon their participation in the preparation of the Offering
Memorandum and any amendments or supplements thereto and review and discussion
of the contents thereof, but are without independent check or verification
except as specified;

          (f)  The Initial Purchasers shall have received on the Closing Date an
opinion, dated the Closing Date, of Skadden, Arps, Slate, Meagher & Flom
(Illinois), counsel for the Initial Purchasers, in form and substance reasonably
satisfactory to the Initial Purchasers.

          (g)  The Initial Purchasers shall have received, at the time this
Agreement is executed and at the Closing Date, letters dated the date hereof or
the Closing Date, in the form and substance satisfactory to the Initial
Purchasers from Coopers & Lybrand L.L.P., independent public accountants,
containing the information and statements of the type ordinarily included in
accountants' "comfort letters" to the Initial Purchasers with respect to the
Initial Purchasers with respect to the financial statements and certain
financial information contained in the Offering Memorandum.

          (h)  The Shares shall have been approved by the NASD for trading and
duly listed in PORTAL and the shares of Common Stock shall have been duly
authorized for listing on the Nasdaq National Market subject to notice of
official issuance.

          (i)  The Company shall have executed the Registration Rights
Agreement, the Deposit Agreement and the Deposit Account Agreement and the
Initial Purchasers shall have received original copies thereof, duly executed by
the Company.

          (j)  The Company shall not have failed at or prior to the Closing Date
to perform or comply with any of the agreements herein contained and required to
be performed or complied with by the Company at or prior to the Closing Date.

     10.  EFFECTIVENESS OF AGREEMENT AND TERMINATION.   This Agreement may be
          ------------------------------------------                         
terminated at any time on or prior to the Closing Date by the Initial Purchasers
by written notice to the Company if any of the following has occurred:  (i) any
outbreak or escalation of hostilities or other national or international
calamity or crisis or change in economic conditions or in the financial markets
of the United States or elsewhere that, in the Initial Purchasers' judgment, is
material and adverse and, in the Initial Purchasers' judgment, makes it
impracticable to market the Securities on the terms and in the manner
contemplated in the Offering Memorandum, (ii) the suspension or material
limitation of trading in securities or other instruments on the New York Stock
Exchange, the American Stock Exchange, the Chicago Board of Options Exchange,
the Chicago Mercantile Exchange, the Chicago Board of Trade or the Nasdaq
National Market or limitation on prices for securities or other instruments on
any such exchange or the Nasdaq National Market, (iii) the suspension of trading
of any securities of the Company on any exchange or in the over-the-counter
market, (iv) the enactment, publication, decree or other promulgation of any
federal or state statute, regulation, rule or order of any court or other
governmental authority which in the opinion of the Initial Purchasers materially
and adversely affects, or will materially and adversely affect, the business,
prospects, financial condition or results of operations of the Company and its
subsidiaries, taken as a whole, (v) the declaration of a banking moratorium by
either federal or New York or Maryland State authorities or (vi) the taking of
any action by any federal, state or local government or agency in respect of its
monetary or fiscal affairs which in your opinion has a material adverse effect
on the financial markets in the United States.

          If on the Closing Date, any one or more of the Initial Purchasers
shall fail or refuse to purchase the Shares which it or they have agreed to
purchase hereunder on such date and the aggregate number of Shares which such
defaulting Initial Purchaser or Initial Purchasers, as the case may be, agreed
but failed or refused to purchase is not more than one-tenth of the aggregate
number of shares to be purchased on such date by all Initial Purchasers, each
non-defaulting Initial Purchaser shall be obligated severally, in the proportion
which the number of Shares set forth opposite its name in Schedule A bears to
the aggregate number of Shares which all the non-defaulting Initial Purchasers,
as the case may be, have agreed to purchase, or in such other proportion as the
Initial Purchasers may specify, to purchase the Shares which such defaulting
Initial Purchaser or Initial Purchasers, as the case may be, agreed but failed
or refused to purchase on such date; provided that in no event shall the
aggregate number of Shares which any Initial Purchaser has agreed to purchase
pursuant to Section 2 hereof be increased pursuant to this Section 10 by an
amount in excess of one-ninth of such number of Shares without the written
consent of such Initial Purchaser.  If on the Closing Date, any Initial
Purchaser or Initial Purchasers shall fail or refuse to purchase the Shares and
the aggregate number of Shares with respect to which such default occurs is more
than one-tenth of the aggregate number of Shares to be purchased by all Initial
Purchasers and arrangements satisfactory to the Initial Purchasers and the
Company for purchase of such Shares are not made within 48 hours after such
default, this Agreement will terminate without liability on the part of any non-
defaulting Initial Purchaser and the Company.  In any such case which does not
result in termination of this Agreement, either you or the Company shall have
the right to postpone the Closing Date, but in no event for longer than seven
days, in order that the required changes, if any, in the Offering Memorandum or
any other documents or arrangements may be effected.  Any action 

                                      22
<PAGE>
 
taken under this paragraph shall not relieve any defaulting Initial Purchaser
from liability in respect of any default of any such Initial Purchaser under
this Agreement.

     11.  MISCELLANEOUS.  Notices given pursuant to any provision of this
