effective until the closing of the Exchange Offer and (iv) to consummate the
Exchange Offer within 150 days following the Closing Date.  The Exchange
Securities will be issued under the Indenture.  Upon the effectiveness of the
Exchange Offer Registration Statement, the Company shall promptly commence the
Exchange Offer, it being the objective of such Exchange Offer to enable each
Holder (other than Participating Broker-Dealers (as defined in Section 3(f)
hereof) eligible and electing to exchange Registrable Securities for Exchange
Securities (assuming that such Holder is not an affiliate of the Company within
the meaning of Rule 405 under the 1933 Act, acquires the Exchange Securities in
the ordinary course of such Holder's business and has no arrangements or
understandings with any person to participate in the Exchange Offer for the
purpose of distributing the Exchange Securities) to

 
                                       5

trade such Exchange Securities from and after their receipt without any
limitations or restrictions under the 1933 Act.

          In connection with the Exchange Offer, the Company shall:

          (i)   mail to each Holder, at its address reflected on the security
     register, a copy of the Prospectus forming part of the Exchange Offer
     Registration Statement, together with an appropriate letter of transmittal
     (a "Letter of Transmittal") and related documents;

          (ii)  keep the Exchange Offer open for not less than 30 calendar days
     after the date notice thereof is mailed to the Holders (or longer if
     required by applicable law);

          (iii) permit Holders to withdraw tendered Registrable Securities at
     any time prior to the close of business, New York City time, on the last
     business day on which the Exchange Offer shall remain open, by sending to
     the institution specified in the notice, a telegram, telex, facsimile
     transmission or letter setting forth the name of such Holder, the principal
     amount of Registrable Securities delivered for exchange, and a statement
     that such Holder is withdrawing his election to have such Securities
     exchanged; and

          (iv)  otherwise comply in all respects with all applicable laws
     relating to the Exchange Offer.

          As soon as practicable after the close of the Exchange Offer, the
Company shall:

          (i)   accept for exchange Registrable Securities duly tendered and not
     validly withdrawn pursuant to the Exchange Offer in accordance with the
     terms of the Exchange Offer Registration Statement and the Letter of
     Transmittal;

          (ii)  deliver, or cause to be delivered, to the Trustee for
     cancellation all Registrable Securities so accepted for exchange by the
     Company; and

          (iii) cause the Trustee promptly to authenticate and deliver Exchange
     Securities to, or upon the instructions of, each Holder of Registrable
     Securities equal in principal amount to the Registrable Securities of such
     Holder so accepted for exchange.

          Interest on each Exchange Security will accrue from the last date on
which interest was paid on the Registrable Securities surrendered in exchange
therefor or, if no interest has been paid on the Registrable Securities, from
the date of its original issue.  The

 
                                       6

Exchange Offer shall not be subject to any conditions, other than that the
Exchange Offer, or the making of any exchange by a Holder, does not violate
applicable law or any applicable interpretation of the Staff of the SEC.  Each
Holder of Registrable Securities (other than Participating Broker-Dealers) who
wishes to exchange such Registrable Securities for Exchange Securities in the
Exchange Offer will be required to represent that (i) it is not an affiliate of
United or the Company, (ii) any Exchange Securities to be received by it were
acquired in the ordinary course of its business and (iii) at the time of the
commencement of the Exchange Offer, it has no arrangement with any person to
participate in the distribution (within the meaning of the 1933 Act) of the
Exchange Securities.  The Company shall inform the Initial Purchaser of the
names and addresses of the Holders to whom the Exchange Offer is made, and the
Initial Purchaser shall have the right to contact such Holders and otherwise
facilitate the tender of Registrable Securities in the Exchange Offer.

          (b) Shelf Registration.  (i) If, because of any change in law or
              ------------------                                          
applicable interpretations thereof by the Staff of the SEC, the Company is not
permitted to effect the Exchange Offer as contemplated by Section 2(a) hereof,
(ii) upon the request of the Initial Purchaser (with respect to any Registrable
Securities which it acquired directly from the Company) within 30 calendar days
after the Closing Date if the Initial Purchaser shall hold Registrable
Securities which it acquired directly from the Company and if the Initial
Purchaser is not permitted, in the opinion of counsel to the Initial Purchaser
addressed to the Company (which counsel shall be reasonably acceptable to the
Company), pursuant to applicable law or applicable interpretation of the Staff
of the SEC to participate in the Exchange Offer, or (iii) if any Holder other
than the Initial Purchaser is not eligible to participate in the exchange offer
due to a change in law or the applicable interpretation of the staff of the
Commission and such holder so notifies the Company, the Company shall, at its
cost,

          (A) as promptly as practicable, file with the SEC a Shelf Registration
     Statement relating to the offer and sale of the Registrable Securities
     (limited solely to the Initial Purchaser if clause (ii) alone applies) by
     the Holders from time to time in accordance with the methods of
     distribution elected by the Majority Holders of such Registrable Securities
     and set forth in such Shelf Registration Statement, and use its best
     efforts to cause such Shelf Registration Statement to be declared effective
     by the SEC by the later of (1) 120 days after the Closing Date and (2) 45
     days after publication of the change in law or interpretation.  In the
     event that the Company is required to file a Shelf Registration Statement
     upon the request of the Initial Purchaser pursuant to clause (ii) above,
     the Company shall file and have declared effective by the SEC both an
     Exchange Offer Registration Statement pursuant to Section 2(a) hereof with
     respect to all Registrable Securities and a Shelf Registration Statement
     (which may be a combined Registration Statement with the Exchange Offer
     Registration Statement) with respect to offers and sales of Registrable
     Securities held by the Initial Purchaser after completion of the Exchange
     Offer;

 
                                       7

          (B) use its best efforts to keep the Shelf Registration Statement
     continuously effective in order to permit the Prospectus forming part
     thereof to be usable by Holders for a period of (i), in the case of clause
     2(b)(i) above, three years from the date the Shelf Registration Statement
     is declared effective by the SEC, or (ii) in the case of clauses 2(b)(ii)
     and 2(b)(iii) above, three years after the closing date, or in any case
     such shorter period which will terminate when all of the Registrable
     Securities covered by the Shelf Registration Statement have been sold
     pursuant to the Shelf Registration Statement or cease to be outstanding;
     and

          (C) notwithstanding any other provisions hereof, use its best efforts
     to ensure that (i) any Shelf Registration Statement complies in all
     material respects with the 1933 Act and the rules and regulations
     thereunder, (ii) any Shelf Registration Statement does not, when it becomes
     effective, contain an untrue statement of a material fact or omit to state
     a material fact required to be stated therein or necessary to make the
     statements therein not misleading and (iii) any Prospectus forming part of
     any Shelf Registration Statement, and any supplement to such Prospectus (as
     amended or supplemented from time to time), does not include an untrue
     statement of a material fact or omit to state a material fact necessary in
     order to make the statements, in light of the circumstances under which
     they were made, not misleading.

          The Company further agrees, if necessary, to supplement or amend the
Shelf Registration Statement if reasonably requested by the Majority Holders
with respect to information relating to the Holders and otherwise as required by
Section 3(b) below, to use all reasonable efforts to cause any such amendment to
become effective and such Shelf Registration to become usable as soon as
thereafter practicable and to furnish to the Holders of Registrable Securities
copies of any such supplement or amendment promptly after its being used or
filed with the SEC.

          (c) Expenses.  The Company shall pay all Registration Expenses in
              --------                                                     
connection with the registration pursuant to Section 2(a) or 2(b).

          (d) Effective Registration Statement.  An Exchange Offer Registration
              --------------------------------                                 
Statement pursuant to Section 2(a) hereof or a Shelf Registration Statement
pursuant to Section 2(b) hereof will not be deemed to have become effective
unless it has been declared effective by the SEC; provided, however, that if,
                                                  --------  -------          
after it has been declared effective, the offering of Registrable Securities
pursuant to a Registration Statement is interfered with by any stop order,
injunction or other order or requirement of the SEC or any other governmental
agency or court, such Registration Statement will be deemed not to have been
effective during the period of such interference, until the offering of
Registrable Securities pursuant to such Registration Statement may legally
resume.

          (e) Increase in Interest Rate.  In the event that (i) the Exchange

Offer Registration Statement is not filed with the SEC on or prior to the 30th
calendar day after the

 
                                       8

staff of the Commission do not permit the Company to effect the Exchange Offer,
in which case clause (iv) shall apply), (ii) the Exchange Offer Registration
Statement is not initially declared effective on or prior to the 120th calendar

in the case of clause (i) above, such 120-day period in the case of clause (ii)
above, such 150-day period in the case of clause (iii) above or such 120-day or
45-day period in the case of clause (iv) above (as applicable); provided that
                                                                --------     
the aggregate increase in such interest rate will in no event exceed one-half of

120-day period described in clause (ii) above, (C) the consummation of the

the Initial Purchaser and the Holders, the Company acknowledges that any failure
by the Company to comply with its obligations under Section 2(a) and Sections
2(b) hereof may result in material irreparable injury to the Initial Purchaser
or the Holders for which there is no adequate remedy at law, that it will not be
possible to measure damages for such injuries precisely and that, in the event
of any such failure, the Initial Purchaser or any Holder may obtain such relief
as may be required to specifically enforce the Company's obligations under
Section 2(a) and Section 2(b) hereof.

          (g) Acknowledgment of Holders.  Each Holder shall be deemed to have
              -------------------------                                      
agreed that any broker-dealer and any such Holder using the Exchange Offer to
participate in a distribution of the securities to be acquired in the Exchange
Offer must comply with the registration and prospectus delivery requirements of
the 1933 Act in connection with secondary resale transactions and that such
secondary resale transactions should be covered by an effective registration
statement.

                                      10

          (d) use its best efforts to register or qualify the Registrable
Securities under all applicable state securities or "blue sky" laws of such
jurisdictions as any Holder of Registrable Securities covered by a Registration
Statement and each underwriter of an underwritten offering of Registrable
Securities shall reasonably request in writing by the time the applicable
Registration Statement is declared effective by the SEC, to cooperate with the
Holders in connection with any filings required to be made with the NASD, and do
any and all other acts and things which may be reasonably necessary or advisable
to enable such Holder to consummate the disposition in each such jurisdiction of
such Registrable Securities owned by such Holder; provided, however, that the
                                                  --------  -------          
Company shall not be required to (i) qualify as a foreign corporation or as a
dealer in securities in any jurisdiction where it would not otherwise be
required to qualify but for this Section 3(d) or (ii) take any action which
would subject it to general service of process or taxation in any such
jurisdiction if it is not then so subject;

          (e) in the case of a Shelf Registration, notify each Holder of
Registrable Securities and counsel for the Initial Purchaser promptly and, if
requested by such Holder or counsel, confirm such advice in writing promptly (i)
when a Registration Statement has become effective and when any post-effective
amendments and supplements thereto become effective, (ii) of any request by the
SEC or any state securities authority for post-effective amendments and
supplements to a Registration Statement and Prospectus or for additional
information after the Registration Statement has become effective, (iii) of the
issuance by the SEC or any state securities authority of any stop order
suspending the effectiveness of a Registration Statement or the initiation of
any proceedings for that purpose, (iv) if, between the effective date of a
Registration Statement and the closing of any sale of Registrable Securities
covered thereby, the representations and warranties of the Company contained in
any underwriting agreement, securities sales agreement or other similar
agreement, if any, relating to such offering cease to be true and correct in all
material respects, (v) of the receipt by the Company of any notification with
respect to the suspension of the qualification of the Registrable Securities for
sale in any jurisdiction or the initiation or threatening of any proceeding for
such purpose, (vi) of the happening of any event or the discovery of any facts
during the period a Shelf Registration Statement is effective which makes any
statement made in such Registration Statement or the related Prospectus untrue
in any material respect or which requires the making of any changes in such
Registration Statement or Prospectus in order to make the statements therein not
misleading and (vii) of any determination by the Company that a post-effective
amendment to a Registration Statement would be appropriate;

          (f) a reasonable time prior to the filing of any Registration
Statement, any Prospectus, any amendment to a Registration Statement or
amendment or supplement to a Prospectus or any document which is to be
incorporated by reference into a Registration Statement or a Prospectus after
initial filing of a Registration Statement, provide copies of such document to
the Initial Purchaser and its counsel (and, in the case of a Shelf Registration
Statement, the Holders and their counsel) and make representatives of the
Company as shall be reasonably requested by the Initial Purchaser and their
counsel (and, in

 
                                      11

the case of a Shelf Registration Statement, the Holders or their counsel)
available for discussion of such document and shall not at any time file or make
any amendment to the Registration Statement, any Prospectus or any amendment of
or supplement to a Registration Statement or a Prospectus or any document which
is to be incorporated by reference into a Registration Statement or a
Prospectus, of which the Initial Purchaser and its counsel (and, in the case of
a Shelf Registration Statement, the Holders and their counsel) shall not have
previously been advised and furnished a copy or to which the Initial Purchaser
or its counsel (and, in the case of a Shelf Registration Statement, the Holders
or their counsel) shall reasonably object unless counsel for the Company advises
the Company that such filing by the Company is required under applicable law;

          (g) (i) in the case of an Exchange Offer, furnish counsel for the
Initial Purchaser and (ii) in the case of a Shelf Registration, furnish counsel
for the Holders of Registrable Securities copies of any request by the SEC or
any state securities authority for amendments or supplements to a Registration

          (h) make every reasonable effort to obtain the withdrawal of any order
suspending the effectiveness of a Registration Statement as soon as practicable
and provide immediate notice to each Holder of the withdrawal of any such order;

          (i) in the case of a Shelf Registration, furnish to each Holder of
Registrable Securities, without charge, at least one conformed copy of each
Registration Statement and any post-effective amendment thereto (without
documents incorporated therein by reference or exhibits thereto, unless
requested);

          (j) in the case of a Shelf Registration, cooperate with the selling
Holders of Registrable Securities to facilitate the timely preparation and
delivery of certificates representing Registrable Securities to be sold and not
bearing any restrictive legends; and cause such Registrable Securities to be in
such denominations (consistent with the provisions of the Indenture) and
registered in such names as the selling Holders or the underwriters, if any, may
reasonably request at least two business days prior to the closing of any sale
of Registrable Securities;

          (k) in the case of a Shelf Registration, upon the occurrence of any
event or the discovery of any facts, each as contemplated by Section 3(e)(vi)
hereof, use its best efforts to prepare a supplement or post-effective amendment
to a Registration Statement or the related Prospectus or any document
incorporated therein by reference or file any other required document so that,
as thereafter delivered to the purchasers of the Registrable Securities, such
Prospectus will not contain at the time of such delivery any untrue statement of
a material fact or omit to state a material fact necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading.  The Company agrees to notify each Holder to suspend use of the
Prospectus as promptly as practicable after

 
                                      12

the occurrence of such an event, and each Holder hereby agrees to suspend use of
the Prospectus until the Company has amended or supplemented the Prospectus to
correct such misstatement or omission.  At such time as such public disclosure
is otherwise made or the Company determines that such disclosure is not
necessary, in each case to correct any misstatement of a material fact or to
include any omitted material fact, the Company agrees promptly to notify each
Holder of such determination and to furnish each Holder such numbers of copies
of the Prospectus, as amended or supplemented, as such Holder may reasonably
request;

          (l) obtain a CUSIP number for all Exchange Securities, or Registrable
Securities, as the case may be, not later than the effective date of a
Registration Statement, and provide the Trustee with printed certificates for
the Exchange Securities or the Registrable Securities, as the case may be, in a
form eligible for deposit with the Depositary;

          (m) (i) cause the Indenture to be qualified under the Trust Indenture
Act of 1939, as amended (the "TIA"), in connection with the registration of the
Exchange Securities, or Registrable Securities, as the case may be, (ii)
cooperate with the Trustee and the Holders to effect such changes to the
Indenture as may be required for the Indenture to be so qualified in accordance
with the terms of the TIA and (iii) execute, and use its best efforts to cause
the Trustee to execute, all documents as may be required to effect such changes,
and all other forms and documents required to be filed with the SEC to enable
the Indenture to be so qualified in a timely manner;

          (n) in the case of a Shelf Registration, enter into agreements
(including customary underwriting agreements) and take all other customary and
appropriate actions (including those reasonably requested by the Majority
Holders) in order to expedite or facilitate the disposition of such Registrable
Securities and in such connection whether or not an underwriting agreement is
entered into and whether or not the registration is an underwritten
registration:

          (i)  to the extent possible, make such representations and warranties
     to the Holders of such Registrable Securities and the underwriters, if any,
     in form, substance and scope as are customarily made by issuers to
     underwriters in similar underwritten offerings as may be reasonably
     requested by them;

          (ii) obtain opinions of counsel to the Company and, subject to the
     proviso in the first sentence of the last paragraph of this clause (n),
     updates thereof (which counsel and opinions (in form, scope and substance)
     shall be reasonably satisfactory to the managing underwriters, if any, and
     the Majority Holders of the Registrable Securities being sold) addressed to
     each selling Holder and the underwriters, if any, covering the matters
     customarily covered in opinions requested in sales of securities or
     underwritten offerings and such other matters as may be reasonably
     requested by such Holders and underwriters;

 
                                      13

          (iii) obtain "cold comfort" letters and, subject to the proviso in the
     first sentence of the last paragraph of this clause (n), updates thereof
     from the Company's independent certified public accountants addressed to
     the underwriters, if any, and use reasonable best efforts to have such
     letter addressed to the selling Holders of Registrable Securities, such
     letters to be in customary form and covering matters of the type
     customarily covered in "cold comfort" letters to underwriters in connection
     with similar underwritten offerings;

          (iv)  enter into a securities sales agreement with the Holders and an
     agent of the Holders providing for, among other things, the appointment of
     such agent for the selling Holders for the purpose of soliciting purchases
     of Registrable Securities, which agreement shall be in form, substance and
     scope customary for similar offerings;

          (v)   if an underwriting agreement is entered into, cause the same to
     set forth indemnification provisions and procedures substantially
     equivalent to the indemnification provisions and procedures set forth in
     Section 6 hereof with respect to the underwriters and all other parties to
     be indemnified pursuant to said Section; and

          (vi)  deliver such other documents and certificates as may be
     reasonably requested and as are customarily delivered in similar offerings.

The above shall be done at (i) the effectiveness of such Registration Statement
(and, if appropriate, each post-effective amendment thereto) and (ii) each
closing under any underwriting or similar agreement as and to the extent
required thereunder; provided that the updates referred to in clauses (ii) and
                     --------                                                 
(iii) of this paragraph (n) shall only be required in the case of (A) any
closing with respect to sales under such Shelf Registration Statement of
Securities having a principal amount of $7.5 million or more or, if the Initial
Purchaser shall waive such updates under clause (A), then (B) in the case of up
to three such closings.  In the case of any underwritten offering, the Company
shall provide written notice to the Holders of all Registrable Securities of
such underwritten offering at least 30 days prior to the filing of a prospectus
supplement for such underwritten offering.  Such notice shall (x) offer each
such Holder the right to participate in such underwritten offering, (y) specify
a date, which shall be no earlier than 10 days following the date of such
notice, by which such Holder must inform the Company of its intent to
participate in such underwritten offering and (z) include the instructions such
Holder must follow in order to participate in such underwritten offering;

          (o) in the case of a Shelf Registration, make available for inspection
by one representative appointed by the Majority Holders of the Registrable
Securities and any underwriters participating in any disposition pursuant to a
Shelf Registration Statement and one counsel or accountant retained by such
Holders or underwriters, all financial and other records, pertinent corporate
documents and properties of the Company reasonably requested by any such
persons, and cause the respective officers, directors, employees, and any other

 
                                      14

agents of the Company to supply all information reasonably requested by any such
representative, underwriter, special counsel or accountant in connection with a
Registration Statement; provided, however, that any records, information or
                        --------  -------                                  
documents that are designated by the Company as confidential at the time of
delivery of such records, information or documents shall be kept confidential by
such persons, unless (i) such records, information or documents are in the
public domain or otherwise publicly available; (ii) disclosure of such records,
information or documents is required by court or administrative order, provided
that such person will, promptly upon learning that disclosure of such
information is sought in a court of competent jurisdiction, give notice to the
Company so that the Company may at its expense undertake appropriate action to
prevent disclosure of the information deemed to be confidential, (iii)
disclosure of such records, information or documents, in the opinion of counsel
to such person, is otherwise required by law (including, without limitation,
pursuant to the requirements of the 1933 Act) or (iv) upon the advice of
counsel, disclosure of such records, information or documents is necessary to
avoid or correct a misstatement or omission in the Registration Statement;

          (p) in the case of a Shelf Registration, use its best efforts to cause
all Registrable Securities to be listed on any securities exchange on which
similar debt securities issued by the Company are then listed if requested in
writing by the Majority Holders or by the underwriter or underwriters of an
underwritten offering of Registrable Securities, if any;

          (q) in the case of a Shelf Registration, use its best efforts to cause
the Registrable Securities to be rated with the appropriate rating agencies, if
so requested by the Majority Holders or by the underwriter or underwriters of an
underwritten offering of Registrable Securities, if any, unless the Registrable
Securities are already so rated;

          (r) otherwise use its best efforts to comply with all applicable rules
and regulations of the SEC and make available to its security holders, as soon
as reasonably practicable, an earnings statement covering at least 12 months
which shall satisfy the provisions of Section 11(a) of the 1933 Act and Rule 158
thereunder; and

          (s) cooperate and assist in any filings required to be made with the
NASD and in the performance of any due diligence investigation by any
underwriter and its counsel.

          In the case of a Shelf Registration Statement, the Company may (as a
condition to such Holder's participation in the Shelf Registration) require each
Holder of Registrable Securities to furnish to the Company such information
regarding such Holder and the proposed distribution by such Holder of such
Registrable Securities as the Company may from time to time reasonably request
in writing.

          In the case of a Shelf Registration Statement, each Holder agrees
that, upon receipt of any notice from the Company of the happening of any event
or the discovery of any facts, each of the kind described in Section 3(e)(ii)-
(vi) hereof, such Holder will

 
                                      15

forthwith discontinue disposition of Registrable Securities pursuant to a
Registration Statement until such Holder's receipt of the copies of the
supplemented or amended Prospectus contemplated by Section 3(k) hereof, and, if
so directed by the Company, such Holder will deliver to the Company (at its
expense) all copies in its possession or certify in writing that such copies
have been destroyed, in each case other than permanent file copies then in such
Holder's possession, of the Prospectus covering such Registrable Securities
current at the time of receipt of such notice.  If the Company shall give any
such notice to suspend the disposition of Registrable Securities pursuant to a
Shelf Registration Statement as a result of the happening of any event or the
discovery of any facts, each of the kind described in Section 3(e)(vi) hereof,
the Company shall be deemed to have used its best efforts to keep the Shelf
Registration Statement effective during such period of suspension provided that
the Company shall use its best efforts to file and have declared effective (if
an amendment) as soon as practicable an amendment or supplement to the Shelf
Registration Statement and shall extend the period during which the Registration
Statement shall be maintained effective pursuant to this Agreement by the number
of days during the period from and including the date of the giving of such
notice to and including the date when the Holders shall have received copies of
the supplemented or amended Prospectus necessary to resume such dispositions.

          4.   Underwritten Registrations.  If any of the Registrable Securities
               --------------------------                                       
covered by any Shelf Registration are to be sold in an underwritten offering as
contemplated by Section 3 hereof, the investment banker or investment bankers
and manager or managers (and their counsel) that will manage the offering will
be agreed to by the Company and the Majority Holders of such Registrable
Securities included in such offering.

          No Holder of Registrable Securities may participate in any
underwritten registration hereunder unless such Holder (a) agrees to sell such
Holder's Registrable Securities on the basis provided in any underwriting
arrangements approved by the persons entitled hereunder to approve such
arrangements and (b) completes, executes and delivers all questionnaires, powers
of attorney, indemnities, underwriting agreements and other documents required
of such Holder under the terms of such underwriting arrangements.

          5.   Participation of Broker-Dealers in Exchange Offer
               -------------------------------------------------

          (a)  The Staff of the SEC has taken the position that any broker-
dealer that receives Exchange Securities for its own account in the Exchange
Offer in exchange for Registrable Securities that were acquired by such broker-
dealer as a result of market-making or other trading activities (a
"Participating Broker-Dealer") may be deemed to be an "underwriter" within the
meaning of the 1933 Act in connection with any resale of such Exchange Notes.

          The Company understands that it is the Staff's position that if the
Prospectus contained in the Exchange Offer Registration Statement includes a
plan of distribution

 
                                      16

containing a statement to the above effect and the means by which Participating
Broker-Dealers may resell the Exchange Securities owned by them, such Prospectus
may be delivered by Participating Broker-Dealers to satisfy their prospectus
delivery obligations under the 1933 Act in connection with resales of Exchange
Securities for their own accounts, so long as the Prospectus otherwise meets the
requirements of the 1933 Act.

          (b) In light of the above, notwithstanding any other provision of this
Agreement, the Company agrees (x) that the provisions of this Agreement as they
relate to a Shelf Registration shall also apply to an Exchange Offer
Registration to the extent, and with such modifications thereto as may be,
reasonably requested by the Initial Purchaser or one or more Participating
Broker-Dealers, in each case as provided in clause (ii) below, in order to
expedite or facilitate the disposition of any Exchange Securities by
Participating Broker-Dealers consistent with the positions of the Staff recited
in Section 5(a) above and (y) without limiting the preceding clause (x), to
maintain the effectiveness of the Registration Statement for such purposes for
the earlier of one year or until such Participating Broker Dealers have sold all
Exchange Securities (as determined in accordance with FIFO accounting), but in
any event only if applicable interpretations of the Staff continue to require
Prospectus delivery; provided that:
                     --------      

          (i)  the Company shall not be required to amend or supplement the
     Prospectus contained in the Exchange Offer Registration Statement, as would
     otherwise be contemplated by Section 3(k), for a period exceeding 180 days
     after the last Exchange Date (as such period may be extended pursuant to
     the last paragraph of Section 3 of this Agreement) and Participating
     Broker-Dealers shall not be authorized by the Company to deliver and shall
     not deliver such Prospectus after such period in connection with the
     resales contemplated by this Section 5; and

          (ii) the application of the Shelf Registration procedures set forth in
     Section 3 of this Agreement to an Exchange Offer Registration, to the
     extent not required by the positions of the Staff of the SEC or the 1933
     Act and the rules and regulations thereunder, will be in conformity with
     the reasonable request to the Company by the Initial Purchaser or with the
     reasonable request in writing to the Company by one or more broker-dealers
     who certify to the Initial Purchaser and the Company in writing that they
     anticipate that they will be Participating Broker-Dealers; and provided
                                                                    --------
     further that, in connection with such application of the Shelf Registration
     -------                                                                    
     procedures set forth in Section 3 to an Exchange Offer Registration, the
     Company shall be obligated (x) to deal only with one entity representing
     the Participating Broker-Dealers, which shall be the Initial Purchaser
     unless it elects not to act as such representative, (y) to pay the fees and
     expenses of only one counsel representing the Participating Broker-Dealers,
     which shall be counsel to the Initial Purchaser unless such counsel elects
     not to so act and (z) to cause to be delivered only one, if any, "cold
     comfort" letter with respect to the Prospectus in the form existing on the

          (c) The Initial Purchaser shall have no liability to the Company or

          Section 6.  Indemnification.  (a)  The Company and United each agree
                      ---------------                                         
jointly and severally to indemnify and hold harmless the Initial Purchaser, each
Holder, including Participating Broker Dealers, each underwriter who
participated in an offering of the Registrable Securities and each person, if
any, who controls such parties within the meaning of Section 15 of the 1933 Act
as follows:

          (i)   against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, arising out of an untrue statement or alleged
     untrue statement of a material fact contained in the Registration Statement
     (or any amendment thereto) or the omission or alleged omission therefrom of
     a material fact required to be stated therein or necessary to make the
     statements therein not misleading or arising out of an untrue statement or
     alleged untrue statement of a material fact included in any preliminary
     prospectus or the Prospectus (or any amendment or supplement thereto) or
     the omission or alleged omission therefrom of a material fact necessary in
     order to make the statements therein, in the light of the circumstances
     under which they were made, not misleading;

          (ii)  against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, to the extent of the aggregate amount paid in
     settlement of any litigation, or investigation or proceeding by any
     governmental agency or body, commenced or threatened, or of any claim
     whatsoever based upon any such untrue statement or omission, or any such
     alleged untrue statement or omission, if such settlement is effected with
     the written consent of the Company; and

          (iii) against any and all expense whatsoever, as incurred (including
     fees and disbursements of counsel chosen by you), reasonably incurred in
     investigating, preparing or defending against any litigation, or
     investigation or proceeding by any governmental agency or body, commenced
     or threatened, or any claim whatsoever based upon any such untrue statement
     or omission, or any such alleged untrue statement or omission, to the
     extent that any such expense is not paid under subparagraph (i) or (ii)
     above;

provided, however, that this indemnity agreement does not apply to any loss,
- --------  -------                                                           
liability, claim, damage or expense to the extent arising out of an untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Company or
United by the Initial Purchaser expressly for use in the Registration Statement
(or any amendment thereto) or any preliminary prospectus or the

 
                                      18

Prospectus (or any amendment or supplement thereto); and provided, further, that
                                                         --------  -------      
the Company will not be liable to the Initial Purchaser or any person
controlling the Initial Purchaser with respect to any such untrue statement or
omission made in any preliminary prospectus that is corrected in the Prospectus
(or any amendment or supplement thereto) if the person asserting any such loss,
claim, damage or liability purchased Securities from the Initial Purchaser in
reliance upon a preliminary prospectus but was not sent or given a copy of the
Prospectus (as amended or supplemented) at or prior to the written confirmation
of the sale of such Securities to such person in any case where such delivery of
the Prospectus (as so amended or supplemented) is required by the 1933 Act,
unless such failure to deliver the Prospectus (as amended or supplemented) was a
result of noncompliance by the Company with Section 3 of this Agreement.

          (b) The Initial Purchaser agrees to indemnify and hold harmless each
of the Company, United and each person, if any, who controls the Company or
United within the meaning of Section 15 of the 1933 Act, against any and all
loss, liability, claim, damage and expense described in the indemnity agreement
in Section (a), as incurred, but only with respect to untrue statements or
omissions, or alleged untrue statements or omissions, made in the Registration
Statement (or any amendment thereto), or any preliminary prospectus or the
Prospectus (or any amendment or supplement thereto) in reliance upon and in
conformity with written information furnished to the Company or United by the
Initial Purchaser expressly for use in the Registration Statement (or any
amendment thereto), or such preliminary prospectus or the Prospectus (or any
amendment or supplement thereto).

          (c) In the case of a Shelf Registration, each Holder agrees, severally
and not jointly, to indemnify and hold harmless the Company, United, the Initial
Purchaser, each underwriter who participates in an offering of Registrable
Securities and the other selling Holders and each person, if any, who controls
such persons within the meaning of Section 15 of the 1933 Act, against any and
all losses, liabilities, claims, damages and expenses described in the indemnity
contained in (a) hereof, as incurred, but only with respect to untrue statements
or omissions, or alleged untrue statements or omissions, made in the
Registration Statement (or any amendment thereto) or the Prospectus (or any
amendment or supplement thereto) in reliance upon and in conformity with written
information furnished to the Company or United by such Holder, expressly for use
in the Registration Statement (or any amendment thereto), or the Prospectus (or
any amendment or supplement thereto); provided, however, that no such Holder
                                      --------  -------                     
shall be liable for any claims hereunder in excess of the amount of net proceeds
received by such Holder from the sale of Registrable Securities pursuant to such
Shelf Registration Statement.

          (d) Each indemnified party shall give prompt notice to each
indemnifying party of any action commenced against it in respect of which
indemnity may be sought hereunder, but failure to so notify an indemnifying
party shall not relieve it from any liability which it may have otherwise than
on account of this indemnity agreement.  An indemnifying

 
                                      19

party may participate at its own expense in the defense of such action.  In no
event shall the indemnifying party or parties be liable for the fees and
expenses of more than one counsel for all indemnified parties in connection with
any one action or separate but similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances.

          (e) In order to provide for just and equitable contribution in
circumstances under which the indemnity provided for in this Section 6 is for
any reason held to be unenforceable by the indemnified parties although
applicable in accordance with its terms, the Company, United and the Initial
Purchaser shall contribute to the aggregate losses, liabilities, claims, damages
and expenses of the nature contemplated by such indemnity incurred by the
Company, United and the Initial Purchaser, as incurred, in such proportions that
the Initial Purchaser is responsible for that portion represented by the
percentage that the initial purchaser's discount appearing on the cover page of
the Prospectus bears to the price to investors appearing thereon, and the
Company and United are responsible for the balance; provided, however, that no
                                                    --------  -------         
person guilty of fraudulent misrepresentation (within the meaning of Section
1(f) of the 1933 Act) shall be entitled to contribution from any person who was
not guilty of such fraudulent misrepresentation.  For purposes of this Section,
each person, if any, who controls the Initial Purchaser within the meaning of
Section 5 of the 1933 Act shall have the same rights to contribution as the
Initial Purchaser, and each director of the Company or United, each officer of
the Company or United who signed the Registration Statement, and each person, if
any, who controls the Company or United within the meaning of Section 5 of the
1933 Act shall have the same rights to contribution as the Company or United.

          7.   Miscellaneous.  (a)  Rule 144 and Rule 144A.  Regardless of
               -------------        ----------------------                
whether the Company is subject to the reporting requirements of Section 13 or 15
of the 1934 Act, the Company covenants that it will file the reports that would
be required to be filed by it under Section 13(a) or 15(d) of the 1934 Act and
the rules and regulations adopted by the SEC thereunder if such Sections were
applicable to it, and that if it ceases to be permitted to file such reports, it
will upon the request of any Holder of Registrable Securities (i) make publicly
available such information as is necessary to permit sales pursuant to Rule 144
under the 1933 Act and (ii) deliver such information to a prospective purchaser
as is reasonably necessary to permit sales pursuant to Rule 144A under the 1933
Act, in each case, to the extent required from time to time to enable such
Holder to sell its Registrable Securities without registration under the 1933
Act within the limitation of the exemptions provided by (x) Rule 144 under the
1933 Act, as such Rule may be amended from time to time, (y) Rule 144A under the
1993 Act, as such Rule may be amended from time to time, or (z) any similar
rules or regulations hereafter adopted by the SEC.  Upon the request of any
Holder of Registrable Securities, the Company will deliver to such Holder a
written statement as to whether it has complied with such requirements.

 
                                      20

          (b) No Inconsistent Agreements.  Neither the Company or United has
              --------------------------                                     
entered into nor will the Company or United on or after the date of this
Agreement enter into, any agreement which is inconsistent with the rights
granted to the Holders of Registrable Securities in this Agreement or otherwise
conflicts with the provisions hereof.   The Company and United represent and
warrant that the rights granted to the Holders hereunder do not conflict with
and are not inconsistent with the rights granted to the holders of the Company's
other issued and outstanding securities under any such agreements.

          (c) Amendments and Waivers.  The provisions of this Agreement,
              ----------------------                                    
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given unless the Company has obtained the written consent of Holders
of at least a majority in aggregate principal amount of the outstanding
Registrable Securities affected by such amendment, modification, supplement,
waiver or departure; provided, however, that no amendment, modification,
                     --------  -------

6 hereof shall be effective as against any Holder of Registrable Securities
unless consented to in writing by such Holder.

given at the time delivered by hand, if personally delivered; three business
days after being deposited in the mail, postage prepaid, if mailed; when
answered back, if telexed; when receipt is acknowledged, if telecopied; and on
the next business day if timely delivered to an air courier guaranteeing

assignment, subsequent Holders; provided that nothing herein shall be deemed to

Agreement or the Indenture.  If any transferee of any Holder shall acquire
Registrable Securities, in any manner, whether by operation of law or otherwise,
such Registrable Securities shall be held subject to all of the terms of this
Agreement, and by taking and holding such Registrable Securities, such Person

the terms and provisions of this Agreement, including the restrictions on resale
set forth in this Agreement and, if applicable, the Purchase Agreement, and such
Person shall be entitled to receive the benefits hereof.

          (f) Third Party Beneficiary.  The Initial Purchaser shall be third
              -----------------------
