necessary for the Registration Statement or a post-effective amendment thereto
to be declared effective before the offering of the Shares may commence, the
Company will endeavor to cause the Registration Statement or such post-effective
amendment to become effective as soon as possible and will advise you promptly
and, if requested by you, will confirm such advice in writing, when the
Registration Statement or such post-effective amendment has become effective.

          (b) The Company will advise you promptly and, if requested by you,
will confirm such advice in writing: (i) of any request by the Commission for
amendment of or a supplement to the Registration Statement, the Prepricing
Prospectuses or the Prospectuses or for additional information; (ii) of the
issuance by the Commission of any stop order suspending the effectiveness of the
Registration Statement or of the suspension of qualification of the Shares for
offering or sale in any jurisdiction or the initiation of any proceeding for
such purpose; and (iii) within the period of time referred to in paragraph (f)
below, of the happening of any event which makes any statement of a material
fact made in the Registration Statement or the Prospectuses untrue or which
requires the making of any additions to or changes in the Registration Statement
or the Prospectuses in order to state a material fact required by the Act or the
regulations thereunder to be stated therein or necessary in order to make the
statements therein not misleading, or of the necessity to amend or supplement
the Prospectuses to comply with the Act or any other law.  If at any time the
Commission shall issue any stop order suspending the effectiveness of the
Registration Statement, the Company will make every reasonable effort to obtain
the withdrawal of such order at the earliest possible time.

          (c) The Company will furnish to you, without charge, four signed
copies of the Registration Statement as originally filed with the Commission and
of each amendment thereto, including financial statements and all exhibits
thereto, and will also furnish to you, without charge, such number of conformed
copies of the Registration Statement as originally filed and of each amendment
thereto, but without exhibits, as you may request.

          (d) The Company will not (i) file any amendment to the Registration
Statement or make any amendment or supplement to the Prospectuses of which you
shall not previously have been

                                       3

 
advised or to which you shall object after being so advised or (ii) so long as,
in the written opinion of counsel for the Managers, a prospectus is required to
be delivered in connection with sales by any Manager or dealer, file any
information, documents or reports pursuant to the Exchange Act, without
delivering a copy of such information, documents or reports to you, as Lead
Managers for the Managers, prior to or concurrently with such filing.

          (e) Prior to the execution and delivery of this Agreement, the Company
has delivered to you, without charge, in such quantities as you have requested,
copies of each form of the International Prepricing Prospectus.  The Company
consents to the use, in accordance with the provisions of the Act and with the

Prospectus, of each International Prepricing Prospectus so furnished by the
Company.

          (f) As soon after the execution and delivery of this Agreement as

expeditiously deliver to each Manager and each dealer, without charge, as many
copies of the International Prospectus as you may request.  The Company consents

such period of time thereafter as the International Prospectus is required by
the Act to be delivered in connection with sales by any Manager or dealer.  If
during such period of time any event shall occur that in the judgment of the
Company or in the opinion of counsel for the Managers is required to be set
forth in the International Prospectus or should be set forth therein in order to
make the statements therein, in the light of the circumstances under which they
were made, not misleading, or if it is necessary to supplement or amend the
International Prospectus to comply with the Act or any other law, the Company
will forthwith prepare and, subject to the provisions of paragraph (d) above,
file with the Commission an appropriate supplement or amendment thereto and will
expeditiously furnish to the Managers and dealers a reasonable number of copies
thereof.

          (g) The Company will cooperate with you and with counsel for the
Managers in connection with the registration or qualification of the Shares for
offering and sale by the several Managers and by dealers under the securities or
Blue Sky laws of such jurisdictions as you may designate and will file such
consents to service of process or other documents necessary or appropriate in
order to effect such registration or qualification; provided that in no event
shall the Company be obligated to qualify to do business in any jurisdiction
where it is not now so qualified or to take any action which would subject it to
service of process in suits, other than those arising out of the offering or
sale of the Shares, in any jurisdiction where it is not now so subject.

          (h) The Company will make generally available to its security holders
a consolidated earnings statement, which need not be audited, covering a twelve-
month period commencing after the effective date of the Registration Statement

execution pursuant to any provisions hereof (otherwise than pursuant to the
second paragraph of Section 10 hereof or by notice given by you terminating this
Agreement pursuant to Section 10 or Section 11 hereof) or if this Agreement
shall be terminated by the Managers because of any failure or refusal on the
part of the Company to comply with the terms or fulfill any of the conditions of

of-pocket expenses (including fees and expenses of counsel for the Managers)
incurred by you in connection herewith.

the time and manner of such filing.

the untrue statement or alleged untrue statement or omission or alleged omission
of a material fact contained in such International Prepricing Prospectus was
corrected in the International Prospectus, provided that the Company has
delivered the International Prospectus to the several Managers in requisite
quantity on a timely basis to permit such delivery or sending.  The foregoing
indemnity agreement shall be in addition to any liability which the Company may
otherwise have.

    (b) If any action, suit or proceeding shall be brought against any Manager
or any person controlling any Manager in respect of which indemnity may be
sought against the Company, such Manager or such controlling person shall
promptly notify the Company, and the Company shall assume the defense thereof,
including the employment of counsel and payment of all fees and expenses.  Such
Manager or any such controlling person shall have the right to employ separate
counsel in any such action, suit or proceeding and to participate in the defense
thereof, but the fees and expenses of such counsel shall be at the expense of
such Manager or such controlling person unless (i) the Company has agreed in
writing to pay such fees and expenses, (ii) the Company has failed to assume the
defense and employ counsel, or (iii) the named parties to any such action, suit
or proceeding (including any impleaded parties) include both such Manager or
such controlling person, and the Company and such Manager or such controlling
person shall have been advised by its counsel that representation of such
indemnified party and the Company by the same counsel would be inappropriate
under applicable standards of professional conduct (whether or not such
representation by the same counsel has been proposed) due to actual or potential
differing interests between them (in which case the Company shall not have the
right to assume the defense of such action, suit or proceeding on behalf of such
Manager or such controlling person).  It is understood, however, that the
Company shall, in connection with any one such action, suit or proceeding or
separate but substantially similar or related actions, suits or proceedings in
the same jurisdiction arising out of the same general allegations or
circumstances, be liable for the reasonable fees and expenses of only one
separate firm of attorneys (in addition to any local counsel) at any time for
all such Managers and controlling persons not having actual or potential
differing interests with you or among themselves, which firm shall be designated
in writing by Smith Barney Inc., and that all such fees and expenses shall be
reimbursed as they are incurred.  The Company shall not be liable for any
settlement of any such action, suit or proceeding effected without its written
consent, but if settled with such written consent, or if there be a final
judgment for the plaintiff in any such action, suit or proceeding, the Company
agrees to indemnify and hold harmless any Manager, to the extent provided in the
preceding paragraph, and any such controlling person from and against any loss,
claim, damage, liability or expense by reason of such settlement or judgment.

                                       13

 
    (c) Each Manager agrees, severally and not jointly, to indemnify and hold
harmless the Company, its directors, its officers who sign the Registration
Statement, and any person who controls the Company within the meaning of Section
15 of the Act or Section 20(a) of the Exchange Act, to the same extent as the
foregoing indemnity from the Company to each Manager, but only with respect to
information relating to such Manager furnished in writing by or on behalf of
such Manager through the Lead Managers expressly for use in the Registration
Statement, the International Prospectus or any International Prepricing
Prospectus, or any amendment or supplement thereto.  If any action, suit or
proceeding shall be brought against the Company, any of its directors, any such
officer, or any such controlling person based on the Registration Statement, the
International Prospectus or any International Prepricing Prospectus, or any
amendment or supplement thereto, and in respect of which indemnity may be sought
against any Manager pursuant to this paragraph (c), such Manager shall have the
rights and duties given to the Company by paragraph (b) above (except that if
the Company shall have assumed the defense thereof such Manager shall not be
required to do so, but may employ separate counsel therein and participate in
the defense thereof, but the fees and expenses of such counsel shall be at such
Manager's expense), and the Company, its directors, any such officer, and any
such controlling person shall have the rights and duties given to the Managers
by paragraph (b) above.  The foregoing indemnity agreement shall be in addition
to any liability which the Managers may otherwise have.

    (d) If the indemnification provided for in this Section 7 is unavailable to
an indemnified party under paragraphs (a) or (c) hereof in respect of any
losses, claims, damages, liabilities or expenses referred to therein, then an
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 or expenses (i) in such proportion
as is appropriate to reflect the relative benefits received by the Company on
the one hand and the Managers on the other hand from the offering of the Shares,
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 on the one hand and the Managers on the other in connection with the
statements or omissions that resulted in such losses, claims, damages,
liabilities or expenses, as well as any other relevant equitable considerations.
The relative benefits received by the Company on the one hand and the Managers
on the other shall be deemed to be in the same proportion as the total net
proceeds from the offering (before deducting expenses) received by the Company
bear to the total underwriting discounts and commissions received by the
Managers, in each case as set forth in the table on the cover page of the
International Prospectus.  The relative fault of the Company on the one hand and
the Managers 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 by the Managers on the other hand and
the parties' relative intent, knowledge, access to information and opportunity
to correct or prevent such statement or omission.

    (e) The Company and the Managers agree that it would not be just and
equitable if contribution pursuant to this Section 7 were determined by a pro
rata allocation (even if the Managers were treated as one entity for such
purpose) or by any other method of allocation that does not take account of the
equitable considerations referred to in paragraph (d) above.  The amount paid or
payable by an indemnified party as a result of the losses, claims, damages,
liabilities and expenses referred to in paragraph (d) above shall be deemed to
include, subject to the limitations set forth above, any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
any claim or defending any such action, suit or proceeding.  Notwithstanding the
provisions of this Section 7, no Manager shall be required to contribute any
amount in excess of the amount by which the total price of the Shares
underwritten by it and distributed to the public exceeds the amount of any
damages which such Manager has otherwise been

                                       14

 
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
Managers' obligations to contribute pursuant to this Section 7 are several in
proportion to the respective numbers of Shares set forth opposite their names in
Schedule I hereto (or such numbers of Shares increased as set forth in Section
10 hereof) and not joint.

    (f)   No indemnifying party shall, without the prior written consent of the
indemnified party, effect any settlement of any pending or threatened action,
suit or proceeding in respect of which any indemnified party is or could have
been a party and indemnity could have been sought hereunder by such indemnified
party, unless such settlement includes an unconditional release of such
indemnified party from all liability on claims that are the subject matter of
such action, suit or proceeding.

    (g)   Any losses, claims, damages, liabilities or expenses for which an
indemnified party is entitled to indemnification or contribution under this
Section 7 shall be paid by the indemnifying party to the indemnified party as
such losses, claims, damages, liabilities or expenses are incurred.  The
indemnity and contribution agreements contained in this Section 7 and the
representations and warranties of the Company set forth in this Agreement shall
remain operative and in full force and effect, regardless of (i) any
investigation made by or on behalf of any Manager or any person controlling any
Manager, the Company, its directors or officers, or any person controlling the
Company, (ii) acceptance of any Shares and payment therefor hereunder, and (iii)
any termination of this Agreement.  A successor to any Manager or any person
controlling any Manager, or to the Company, its directors or officers, or any
person controlling the Company, shall be entitled to the benefits of the
indemnity, contribution, and reimbursement agreements contained in this Section
7.

    8.    Conditions of Managers' Obligations.  The several obligations of the
          -----------------------------------

amendment shall have become effective not later than 5:30 P.M., New York City

statement made in the Prospectuses untrue or which, in the opinion of the
Company and its counsel or the Managers and their counsel, requires the making
of any addition to or change in the Prospectuses in order to state a material
fact required by the Act or any other law to be stated therein or necessary in
order to make the statements therein not misleading, if amending or
supplementing the Prospectuses to reflect such event or development would, in

               ---------------------------                              
effective: (i) upon the execution and delivery hereof by the parties hereto; or
(ii) if, at the time this Agreement is executed and delivered, it is necessary
for the Registration Statement or a post-effective amendment thereto to be
declared effective before the offering of the Shares may commence, when
notification of the effectiveness of the Registration Statement or such post-
effective amendment has been released by the Commission.  Until such time as
this Agreement shall have become effective, it may be terminated by the Company,
by notifying you, or by you, as Lead Managers for the several Managers, by
notifying the Company.

       If any one or more of the Managers shall fail or refuse to purchase
Shares which it or they are obligated to purchase hereunder on the Closing Date,
and the aggregate number of Shares which such defaulting Manager or Managers are
obligated but fail or refuse to purchase is not more than one-tenth of the
aggregate number of Shares which the Managers are obligated to purchase on the
Closing Date, each non-defaulting Manager shall be obligated, severally, in the
proportion which the number of Shares set forth opposite its name in Schedule I
hereto bears to the aggregate number of Shares set forth opposite the names of
all non-defaulting Managers or in such other proportion as you may specify in
accordance with Section 20 of the Master Agreement Among Underwriters of Smith
Barney Inc., to purchase the Shares which such defaulting Manager or Managers
are obligated, but fail or refuse, to purchase.  If any one or more of the
Managers shall fail or refuse to purchase Shares which it or they are obligated
to purchase on the Closing Date and the aggregate number of Shares with respect
to which such default occurs is more than one-tenth of the aggregate number of
Shares which the Managers are obligated to purchase on the Closing Date and
arrangements satisfactory to you and the Company for the purchase of such Shares
by one or more non-defaulting Managers or other party or parties approved by you
and the Company are not made within 36 hours after such default, this Agreement
will terminate without liability on the part of any non-defaulting Manager or
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 Registration Statement and the Prospectus or
any other documents or arrangements may be effected.  Any action taken under
this paragraph shall not relieve any defaulting Manager from liability in
respect of any such default of any such Manager under this Agreement.  The term
"Manager" as used in this Agreement includes, for all purposes of this
Agreement, any party not listed in Schedule I hereto who, with your approval and
the approval of the Company, purchases Shares which a defaulting Manager is
obligated, but fails or refuses, to purchase.

                                       18

 
        Any notice under this Section 10 may be given by telegram, telecopy or
telephone but shall be subsequently confirmed by letter.

        11. Termination of Agreement.  This Agreement shall be subject to
            ------------------------                                     
termination in your absolute discretion, without liability on the part of any
Manager to the Company, by notice to the Company, if prior to the Closing Date,
(i) trading in securities generally on the New York Stock Exchange, the American
Stock Exchange or the Nasdaq National Market shall have been suspended or
materially limited, (ii) a general moratorium on commercial banking activities
in New York or Philadelphia shall have been declared by either federal or state
authorities, or (iii) there shall have occurred any outbreak or escalation of
hostilities or other U.S. or domestic calamity, crisis or change in political,
financial or economic conditions, the effect of which on the financial markets
of the United States is such as to make it, in your judgment, impracticable or
inadvisable to commence or continue the offering of the Shares at the offering
price to the public set forth on the cover page of the International Prospectus
or to enforce contracts for the resale of the Shares by the Managers.  Notice of
such termination may be given to the Company by telegram, telecopy or telephone
and shall be subsequently confirmed by letter.

        12. Information Furnished by the Managers.  The statements set forth in
            -------------------------------------                              
the last paragraph on the cover page, the stabilization legend on the inside
cover page, and the statements in the first, third, seventh, eighth, ninth and
fifteenth paragraphs under the caption "Underwriting" in any International
Prepricing Prospectus and in the International Prospectus, constitute the only
information furnished by or on behalf of the Managers through you as such
information is referred to in Sections 6(b) and 7 hereof.

        13. Miscellaneous.  Except as otherwise provided in Sections 5, 10 and
            -------------                                                     
11 hereof, notice given pursuant to any provision of this Agreement shall be in
writing and shall be delivered (i) if to the Company, at the office of the
Company at Hyperion Telecommunications, Inc., Main at Water Street, Coudersport,
Pennsylvania 16915, Attention: Edward E. Babcock, Jr., Vice President, Finance;
or (ii) if to you, as Lead Managers for the several Managers, care of Smith
Barney Inc., 388 Greenwich Street, New York, New York 10013, Attention: Manager,
Investment Banking Division.

        This Agreement has been and is made solely for the benefit of the
several Managers, the Company, its directors and officers, and the other
controlling persons referred to in Section 7 hereof and their respective
successors and assigns, to the extent provided herein, and no other person shall
acquire or have any right under or by virtue of this Agreement.  Neither the
term "successor" nor the term "successors and assigns" as used in this Agreement
shall include a purchaser from any Manager of any of the Shares in his status as
such purchaser.

        14. Applicable Law; Counterparts.  This Agreement shall be governed by
            ----------------------------                                      
and construed in accordance with the laws of the State of New York applicable to
contracts made and to be performed within the State of New York.

        This Agreement may be signed in various counterparts which together
constitute one and the same instrument.  If signed in counterparts, this
Agreement shall not become effective unless at least one counterpart hereof
shall have been executed and delivered on behalf of each party hereto.

                                       19

between the Company and the several Managers.
