Item 5.   Other Events

     On July 6, 1995, Geotek Communications, Inc. (the "Company"), pursuant
to a purchase agreement dated June 29, 1995 (the "Purchase Agreement"),
issued and sold to Smith Barney Inc. (the "Initial Purchaser") 207,000 units
(the "Units") consisting of $207,000,000 in aggregate principal amount at
maturity of its 15% Senior Secured Discount Notes due 2005 (the "Notes") and
warrants (the "Warrants") to purchase an aggregate of 6,210,000 shares of the
Company's common stock, par value $.01 per share (the "Common Stock"), at an
exercise price of $9.90 per share, which exercise price is subject to adjustment
in certain circumstances set forth in the Warrants. The Initial Purchaser has
the option (the "Over-allotment Option"), exercisable at any time and from time
to time prior to July 29, 1995, to purchase up to an additional 20,700 Units
(with each such Unit consisting of one Note with a principal amount at maturity
of $1,000 and Warrants to purchase 30 shares of Common Stock) at a purchase
price per Unit equal to the Accreted Value (as defined in the Indenture) of the
Note constituting a part of each of such additional Unit. A copy of the Purchase
Agreement is attached hereto as Exhibit (c)(1). The net proceeds to the Company
from the July 6, 1995 sale of the Units were approximately $96.0 million.

     The Notes were issued under an indenture (the "Indenture") meeting the
requirements of the Trust Indenture Act of 1939, as amended.  A copy of the
Indenture is attached hereto as Exhibit (c)(2).  The maximum aggregate
principal amount at maturity of the Notes issuable under the Indenture is
$207,000,000 (plus the aggregate principal amount at maturity of any Notes
issued pursuant to the Over-allotment Option).  No interest will be payable
on the Notes prior to July 15, 2000.  However, the Notes were issued with an
initial Accreted Value of $483.44 per Unit. The Accreted Value of each Note
increases at a rate of 15% per annum, compounded semi-annually, until July 15,
2000 at which time the Accreted Value of each Note will be equal to $1,000. From
and after July 15, 2000, cash interest on the Notes will accrue at the rate of
15% per annum and will be payable semiannually on each July 15 and January 15
commencing January 15, 2001. The Notes mature on July 15, 2005. In addition, the
Company has the option to redeem the Notes, on or after July 15, 2000, in whole
or in part, at redemption prices beginning at 110% of the principal amount
thereof, plus accrued and unpaid interest, if any, to the redemption date, for
the 12 month period beginning July 15, 2000, and declining to 100% of the
principal amount thereof, plus accrued and unpaid interest, if any, to the
redemption date, on or after July 15, 2003. In the event of a sale by the
Company to a Strategic Equity Investor (as defined in the Indenture) on or prior
to July 15, 1998 of Capital Stock (as defined in the Indenture) of the Company
for an aggregate purchase price equal to or exceeding $50,000,000, up to a
maximum of 20% of the aggregate Accreted Value of the Notes will be redeemable
at the option of the Company out of the net proceeds of such sale or sales at a
redemption price equal to 115% of the Accreted Value of the Notes to be redeemed
on the redemption date. In addition, the Company is obligated (a) upon a Change
of Control (as defined in the Indenture) to purchase all outstanding Notes at a
purchase price of 101% of the Accreted Value thereof, plus accrued and unpaid
interest, if any, to the date of purchase and (b) to make an offer to purchase
Notes at a purchase price of 100% of the Accreted Value thereof, plus accrued
and unpaid interest, if any, to the date of purchase with a portion of the net
cash proceeds from certain asset sales.

     The Notes are senior obligations of the Company that rank senior in
right of payment to all Subordinated Indebtedness (as defined in the
Indenture) of the Company and the Guarantors (as defined below).  In
addition, the Company is obligated pursuant to the Indenture to cause certain
of its existing and future wholly owned direct and indirect subsidiaries
organized under the laws of the United States (collectively, the
"Guarantors") to jointly and severally guarantee the Notes.  Pursuant to a
notes registration rights agreement (the "Notes Registration Rights
Agreement"), the Company has agreed to offer the holders of the Notes the
right to exchange the Notes for an equal principal amount of a newly created
series of notes, identical in all material respects to the Notes, registered
under the Securities Act of 1933 as amended (the "Securities Act").  If the
Company fails to effectuate such exchange or otherwise register the Notes
under the Securities Act or otherwise comply with the procedures set forth in
<PAGE>

the Notes Registration Rights Agreement within the time periods prescribed by
the Notes Registration Rights Agreement, the Company will be subject to
substantial monetary penalties.  A copy of the Notes Registration Rights
Agreement is attached hereto as Exhibit (c)(3).

     The Indenture contains certain covenants that, subject to certain
exceptions, restrict the ability of the Company and certain of its
subsidiaries from incurring indebtedness, repurchasing Capital Stock and
subordinated indebtedness, engaging in transactions with affiliates, engaging
in sale-leaseback transactions, incurring or suffering to exist certain
liens, paying dividends or making other distributions, making investments,
selling assets, engaging in mergers and acquisitions and engaging in
businesses other than the telecommunications business.  In addition, the
Indenture imposes limits on the ability of the Company's subsidiaries to
issue preferred stock and to create restrictions on their ability to pay
dividends and make certain other payments to the Company.  The Company is
also required under the Indenture to make all cash investments in its wholly-
owned subsidiaries organized and doing business in the United States in the
form of a loan (each an "Intercompany Loan") and to pledge all such
Intercompany Loans as security for the Company's obligations under the Notes.

     The Notes are secured by a pledge of all of the shares of capital stock
owned or hereafter acquired by the Company in each of National Band Three
Limited, PowerSpectrum, Inc., Geotek Communications GmbH, and the entities
through which the Company owns its interest in Bogen Corporation (each a
"Pledged Company").  The agreements governing these pledges (the "Pledge
Agreements") contain certain covenants with respect to the ability of the
Pledged Companies and their subsidiaries to incur indebtedness and to incur
liens, which covenants are more restrictive than the covenants contained in
the Indenture.  Copies of each of the Pledge Agreements are attached hereto
as Exhibits (c)(4), Exhibit (c)(5), Exhibit (c)(6), respectively.

     In the event the Company obtains the prior written consent of holders of
at least 66 2/3% of the aggregate principal amount of the Notes then
outstanding (the "Requisite Vote"), the Company may terminate the Pledge
Agreements, the guarantees issued by the Guarantors and the provisions in the
Indenture governing the guarantees and the other security arrangements
(including the pledges of the Intercompany Loans) (collectively, the
"Collateral Arrangements").  The Company is required to pay to each holder
voting in any such Company solicitation an amount in cash equal to .50% of
the Accreted Value of its Notes on the date of such vote.  Each such vote is
referred to as a "Collateral Release Request."  In the event the Company does
not receive the Requisite Vote pursuant to a Collateral Release Request, the
Company may, at its option, make an offer to purchase all of the outstanding
Notes at a purchase price of 101.5% of the Accreted Value thereof, plus
accrued and unpaid interest, if any, to the date of repurchase.  Upon the
consummation of any such repurchase offer, the Collateral Arrangements shall
terminate.

     The Warrants are issued under a warrant agreement (the "Warrant
Agreement").  Each Warrant has an exercise price of $9.90 per share, which
exercise price is subject to adjustment in certain circumstances set forth in
the Warrants.  The Warrants are exercisable, in whole or in part, from
January 6, 1996 (the "Exercisability Date") until July 15, 2005 (the
"Expiration Date").  A copy of the Warrant Share Agreement is attached hereto
as Exhibit (c)(7).  Pursuant to a warrant share registration rights agreement
(the "Warrant Share Registration Rights Agreement"), the Company has agreed
to file and use its best efforts to make effective, by the Exercisability
Date, a shelf registration statement under the Securities Act covering the
sale of the shares of Common Stock issuable upon exercise of the Warrants and
to keep such registration statement effective until thirty days after the
Expiration Date.  A copy of the Warrant Share Registration Rights Agreement
is attached hereto as Exhibit (c)(8).
<PAGE>

     Concurrently with the above described issuance and sale of the Units,
the Company, pursuant to a defeasance security agreement (the "Defeasance
Security Agreement"), defeased the Company's Senior Secured Notes due 1998
(the "Defeased Notes") by granting to the holders of the Defeased Notes (the
"Defeased Notes Holders") a first priority security interest in $42,218,000
(principal amount at maturity) of Governmental Obligations (as defined in the
Defeasance Security Agreement).  The Company and the Defeased Notes Holders
are parties to a Note and Warrant Purchase Agreement (the "Note Agreement")
dated as of March 20, 1995.  Pursuant to the terms of the Defeasance Security
Agreement, the Defeased Notes Holders released the security interest granted
to them pursuant to the Note Agreement, including the cancellation and
discharge of the Guarantees and the Pledge Agreement (each as defined in the
Note Agreement).  In addition, pursuant to the terms of the Defeasance
Security Agreement, all of the restrictive covenants contained in the Note
Agreement, including those which limited the Company's ability to incur
indebtedness and to incur liens and those which required the Company to
maintain certain financial thresholds, were terminated.  A copy of the
Defeasance Security Agreement is attached hereto as Exhibit (c)(9).

     The summaries of the Purchase Agreement, the Indenture, the Note
Registration Rights Agreement, the Pledge Agreements, the Warrant Agreement,
the Warrant Shares Registration Rights Agreement and the Defeasance Security
Agreement are qualified in their entirety by reference to the copy of the
applicable document included as an exhibit to this filing.

The Company also proposes, upon the terms and conditions set forth herein, to

The Notes will be secured by pledge agreements entered into by the Company

          The Company wishes to confirm as follows its agreement with the
Initial Purchaser in connection with the purchase and resale of the Units.

          1.   Preliminary Offering Memorandum and Offering Memorandum.  The
Units will be offered and sold to the Initial Purchaser without registration
under the Securities Act of 1933, as amended (the "Act"), in reliance on an
exemption pursuant to Section 4(2) under the Act.  The Company has prepared a
preliminary offering memorandum, dated May 23, 1995, a preliminary offering
memorandum dated June 19, 1995, and a preliminary offering memorandum dated
June 28, 1995 (collectively, the "Preliminary Offering Memorandum"), and an
offering memorandum, dated June 30, 1995 (the "Offering Memorandum"), setting
forth information regarding the Company and the Units.  Any references herein
to the Preliminary Offering Memorandum and the Offering Memorandum shall be
deemed to include all amendments and supplements thereto.  The Company hereby
confirms that it has authorized the use of the Preliminary Offering
Memorandum and the Offering Memorandum in connection with the offering and
resale of the Units by the Initial Purchaser.
<PAGE>

          The Company understands that the Initial Purchaser proposes to make
offers and sales (the "Exempt Resales") of the Units purchased by the Initial
Purchaser hereunder only on the terms and in the manner set forth in the
Offering Memorandum and Section 2 hereof, as soon as the Initial Purchaser
deems advisable after this Agreement has been executed and delivered, (i) to
persons in the United States whom the Initial Purchaser reasonably believes
to be qualified institutional buyers ("Qualified Institutional Buyers") as
defined in Rule 144A under the Act, as such rule may be amended from time to
time ("Rule 144A"), in transactions under Rule 144A, (ii) to a limited number
of other institutional "accredited investors" (as defined in Rule 501(a)(1),
(2), (3) and (7) under Regulation D under the Act) ("Regulation D")
("Accredited Investors") in private sales exempt from registration under the
Act and (iii) outside the United States to persons other than U.S. persons in
reliance upon Regulation S ("Regulation S") under the Act (such persons
specified in clauses (i), (ii) and (iii) being referred to herein as the
"Eligible Purchasers").  As used in this Agreement, the terms "United States"
and "U.S. persons" have the meaning given them in Regulation S.

          It is understood and acknowledged that, upon original issuance
thereof, and until such time as the same is no longer required under the
applicable requirements of the Act, the Notes and the Warrants shall bear the
legends set forth in paragraphs 6 and 7, respectively, under the section of
the Offering Memorandum entitled "Transfer Restrictions."

          It also is understood and acknowledged that holders (including
subsequent transferees) of the Notes will have the registration rights set
forth in the registration rights agreement pertaining to the Notes (the
"Notes Registration Rights Agreement"), to be dated as of the Closing Date,
in substantially the form of Exhibit A hereto, and that the holders(including
subsequent transferees) of the Warrants will have the registration rights set
forth in the registration rights agreement pertaining to the Warrants (the
"Warrant Registration Rights Agreement" and, together with the Notes
Registration Rights Agreement, the "Registration Rights Agreements"), to be
dated the date hereof in substantially the form of Exhibit B hereto.  This
Agreement, the Indenture, the Pledge Agreements, the Registration Rights
Agreements and the Warrant Agreement are hereinafter referred to collectively
as the "Operative Documents."

          Capitalized terms used herein without definition have the
respective meanings specified therefor in the Offering Memorandum.

          2.   Agreements to Sell, Purchase and Resell.  (a)  The Company
hereby agrees, subject to all the terms and conditions set forth herein, to
issue and sell to the Initial Purchaser and, upon the basis of the
representations, warranties and agreements of the Company herein contained
and subject to all the terms and conditions set forth herein, the Initial
Purchaser agrees to purchase from the Company, at a purchase price of
$96,069,197, 207,000 Units.

          (b)  The Company also agrees, subject to all the terms and
conditions set forth herein, to sell to the Initial Purchaser, and, upon the
basis of the representations, warranties and agreements of the Company herein
contained and subject to all the terms and conditions set forth herein, the
Initial Purchaser shall have the right to purchase from the Company pursuant
to an option (the "over-allotment option") which may be exercised at any time
and from time to time prior to 9:00 P.M., New York City time, on the 30th day
after the date of the Offering Memorandum (or, if such 30th day shall be a
Saturday or Sunday or a holiday, on the next business day thereafter when the
New York Stock Exchange is open for trading), up to 20,700 Additional Units
at a purchase price per Unit equal to the Accreted Value of the Additional
Notes constituting a part of each of such Units on the date of delivery and
payment of the Additional Units.

          (c)  The Initial Purchaser has advised the Company that it proposes
to offer the Units for sale upon the terms and conditions set forth in this
Agreement and in the Offering Memorandum.  The Initial Purchaser hereby
represents and warrants to, and agrees with, the Company that the Initial
Purchaser (i) is purchasing the Units pursuant to a private sale exempt from
registration under the Act, (ii) will not solicit offers for, or offer or
sell, the Units by means of any form of general solicitation or general
advertising or in any manner involving a public offering within the meaning
of Section 4(2) of the Act, (iii) will solicit offers for the Units only
from, and will offer, sell or deliver the Units as part of its initial
offering only to (A) persons in the United States whom the Initial Purchaser
<PAGE>

reasonably believes to be Qualified Institutional Buyers, or, if any such
person is buying for one or more institutional accounts for which such person
is acting as fiduciary or agent, only when such person has represented to the
Initial Purchaser that each such account is a Qualified Institutional Buyer,
to whom notice has been given that such sale or delivery is being made in
reliance on Rule 144A, in each case, in a transaction under Rule 144A, (B) to
a limited number of Accredited Investors that make the representations to and
agreements with the Company specified in Exhibit A to the Offering Memorandum
in private sales exempt from registration under the Act and (C) outside the
United States to persons other than U.S. persons in reliance on Regulation S
and (iv) that it will take reasonable steps to ensure that purchasers of
Units in the United States are aware that the Initial Purchaser may rely on
the exemption from the provisions of Section 5 of the Act provided by Rule
144A promulgated thereunder.  The Initial Purchaser has advised the Company
that it will offer the Units to Eligible Purchasers at a price initially
equal to the Accreted Value of the Notes on the date of sale.  Such price may
be changed by the Initial Purchaser at any time thereafter without notice.

          (d)  The Initial Purchaser represents and warrants that it has
offered and sold the Units and agrees that it will offer and sell the Units
(i) as part of its distribution at any time and (ii) otherwise until 40 days
after the later of the commencement of the offering of the Units and the
Closing Date, only in accordance with Rule 903 of Regulation S or as
otherwise permitted pursuant to paragraph (c) above.  Accordingly, the
Initial Purchaser represents and agrees that neither such Initial Purchaser,
its affiliates nor any persons acting on its or their behalf has engaged or
will engage in any directed selling efforts with respect to the Units, and it
and they have complied and will comply with the offering restrictions
requirement of Regulation S.  Such Initial Purchaser agrees that, at or prior
to confirmation of the sale of Units (other than a sale pursuant to Rule
144A), it will have sent to each distributor, dealer or person receiving a
selling concession, fee or other remuneration that purchases Units from such
Initial Purchaser during the restricted period a confirmation or notice to
substantially the following effect:

     "The Securities covered hereby have not been registered under the
     U.S. Securities Act of 1933, as amended (the "Securities Act"), and
     may not be offered or sold within the United States or to, or for
     the account or benefit of, U.S. persons (i) as part of their
     distribution at any time or (ii) otherwise until 40 days after the
     later of the commencement of the offering thereof and the closing
     date of the sale, except in either case in accordance with
     Regulation S (or Rule 144A under the Securities Act) under the
     Securities Act.  Terms used above and not otherwise defined have
     the meaning given to them by Regulation S."

          The Initial Purchaser understands that the Company and, for
purposes of the opinions to be delivered to the Initial Purchaser pursuant to
Sections 7(c) and 7(d) hereof, counsel to the Company and counsel to the
Initial Purchaser, will rely upon the accuracy and truth of the foregoing
representations and agreements and the Initial Purchaser hereby consents to
such reliance.

Initial Purchaser of and payment for the Units shall be made at the offices
of Smith Barney Inc., 388 Greenwich Street, New York, NY 10013, at
10:00 A.M., New York City time, on July 6, 1995 (the "Closing Date").  The
place of closing for the Firm Units and the Closing Date may be varied by
agreement between the Initial Purchaser and the Company.

          Delivery to the Initial Purchaser of and payment for any Additional
Units to be purchased by the Initial Purchaser shall be made at the
aforementioned office of Smith Barney Inc. at such time and on such date
specified by the Initial Purchaser (the "Option Closing Date"), which may be

Closing Date nor earlier than three nor later than ten business days after
the Initial Purchaser gives written notice to the Company of the Initial
Purchaser's determination to purchase the number of Additional Units
specified in such notice.  The place of closing for any Additional Units and
the Option Closing Date for such Additional Units may be varied by agreement
between the Initial Purchaser and the Company.
<PAGE>

          The Firm Units will be delivered to the Initial Purchaser against
payment of the purchase price for the Firm Units therefor as follows:  (i)
$10,000,000 of the purchase price shall be paid by wire transfer of same day
funds, in connection with which the Company shall pay any reasonable interest
or other charges incurred by the Initial Purchaser (which amounts shall be
deducted from such payment); and (ii) the remainder of the purchase price
shall be paid by certified or official bank check or checks payable in New
York Clearing House (next day) funds to the order of the Company.  Any
Additional Units that the Initial Purchaser may elect to purchase will be
paid for as provided in clause (ii) above.  The Notes will be in definitive
or global form and registered in such names and in such denominations as the
Initial Purchaser shall request prior to 1:00 p.m., New York City time, on
the second business day preceding the Closing Date or any Option Closing
Date, as the case may be.  The Units to be delivered to the Initial Purchaser
shall be made available to the Initial Purchaser in New York City for
inspection and packaging not later than 9:30 a.m., New York City time, on the
business day next preceding the Closing Date or the Option Closing Date, as
the case may be.

          4.   Agreements of the Company.  The Company agrees with the
Initial Purchaser as follows:

          (a)  The Company will advise the Initial Purchaser promptly and, if
requested by it, will confirm such advice in writing, within the period of
time referred to in paragraph (e) below, of any change in the Company's
condition (financial or otherwise), business, prospects, properties, net
worth or results of operations, or of the happening of any event which makes
any statement made in the Preliminary Offering Memorandum or the Offering
Memorandum untrue or which requires the making of any additions to or changes
in the Preliminary Offering Memorandum or the Offering Memorandum in order to
make the statements therein not misleading in light of the circumstances
under which they were made, or of the necessity to amend or supplement the
Preliminary Offering Memorandum or the Offering Memorandum to comply with any
law.

          (b)  The Company will furnish to the Initial Purchaser, without
charge, as of the date of the Offering Memorandum, such number of copies of
the Offering Memorandum as the Initial Purchaser may reasonably request.

          (c)  The Company will not make any amendment or supplement to the
Preliminary Offering Memorandum or to the Offering Memorandum of which the
Initial Purchaser shall not previously have been advised or to which it shall
reasonably object after being so advised or file any document with the
Securities and Exchange Commission (the "Commission") which upon filing
becomes incorporated by reference into the Preliminary Offering Memorandum
("an Incorporated Document"), without, in each case, delivering a copy of
such document to the Initial Purchaser prior to such filing.

          (d)  Prior to the execution and delivery of this Agreement, the
Company has delivered or will deliver to the Initial Purchaser, without
charge, in such quantities as the Initial Purchaser shall have requested or
may hereafter reasonably request, copies of the Preliminary Offering
Memorandum.  The Company consents to the use, in accordance with the
securities or "blue sky" laws of the jurisdictions in which the Units are
offered by the Initial Purchaser and by dealers, prior to the date of the
Offering Memorandum, of each Preliminary Offering Memorandum so furnished by
the Company.  The Company consents to the use of the Offering Memorandum in
accordance with the securities or "blue sky" laws of the jurisdictions in
which the Units are offered by the Initial Purchaser and by all dealers to
whom Units may be sold in connection with the offering and sale of the Units.

          (e)  If, at any time prior to completion of the distribution of the
Units by the Initial Purchaser to Eligible Purchasers, any event shall occur
that in the judgment of the Company or the Initial Purchaser or in the
opinion of counsel for the Initial Purchaser should be set forth in the
Offering Memorandum 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 Offering Memorandum, or to file under
the Exchange Act any document which upon filing becomes an Incorporated
<PAGE>

Document, to comply with any law, the Company will forthwith prepare an
appropriate supplement or amendment thereto or file such document under the
Exchange Act, and will expeditiously furnish to the Initial Purchaser and
dealers a reasonable number of copies thereof.  In the event that the Company
and the Initial Purchaser agree that the Offering Memorandum should be
amended or supplemented, or that a document should be filed under the
Exchange Act which upon filing becomes an Incorporated Document, the Company,
if requested by the Initial Purchaser, will promptly issue a press release
announcing or disclosing the matters to be covered by the proposed amendment
or supplement or such document unless such announcement or disclosure, in the
opinion of both counsel to the Company and to the Initial Purchaser, would
jeopardize the ability of the Company to rely on an exemption from
registration under the Act in connection with the sale of the Units
hereunder.

          (f)  The Company will cooperate with the Initial Purchaser and with
its counsel in connection with the qualification of the Units for offering
and sale by the Initial Purchaser and by dealers under the securities or
"blue sky" laws of such jurisdictions as the Initial Purchaser may designate
and will file such consents to service of process or other documents
necessary or appropriate in order to effect such 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 Units, in any jurisdiction where it is not now
so subject.

          (g)  So long as any of the Units, Notes or Warrants are
outstanding, the Company will furnish to the Initial Purchaser (i) as soon as
available, a copy of each report of the Company mailed to stockholders or
filed with the Commission, and (ii) from time to time such other information
concerning the Company as the Initial Purchaser may reasonably request.

          (h)  If this Agreement shall terminate or shall be terminated after
execution and delivery pursuant to any provisions hereof (otherwise than by
notice given by the Initial Purchaser terminating this Agreement pursuant to
Section 9 or Section 10 hereof) or if this Agreement shall be terminated by
the Initial Purchaser because of any failure or refusal on the part of the
Company to comply with the terms or fulfill any of the conditions of this
Agreement, the Company agrees to reimburse the Initial Purchaser for all
out-of-pocket expenses (including fees and expenses of its counsel)
reasonably incurred by it in connection herewith, but without any further
obligation on the part of the Company for loss of profits or otherwise.

          (i)  The Company will apply the net proceeds from the sale of the
Units to be sold by it hereunder substantially in accordance with the
description set forth in the Offering Memorandum under "Use of Proceeds" and
in a manner that will not result in the Company becoming an "investment
company" within the meaning of the Investment Company Act of 1940, as amended
(the "Investment Company Act").

          (j)  Except as stated in this Agreement and in the Preliminary
Offering Memorandum and Offering Memorandum, the Company has not taken, nor
will it take, directly or indirectly, any action designed to or that might
reasonably be expected to cause or result in stabilization or manipulation of
the price of the Units to facilitate the sale or resale of the Units.  Except
as permitted by the Act, the Company will not distribute any offering
material in connection with the Exempt Resales.

          (k)  From and after the Closing Date, so long as any of the Units,
Notes or Warrants are outstanding and are "Restricted Securities" within the
meaning of Rule 144(a)(3) under the Act or, if earlier, until three years
after the Closing Date, and during any period in which the Company is not
subject to Section 13 or 15(d) of the Exchange Act, the Company will furnish
to holders of the Units, Notes and Warrants and prospective purchasers
thereof designated by such holders, upon request of such holders or such
prospective purchasers, the information required to be delivered pursuant to
Rule 144A(d)(4) under the Act to permit compliance with Rule 144A in
connection with resale of the Units, Notes and Warrants.
<PAGE>

          (l)  The Company has complied and will comply with all provisions
of Florida Statutes Section 517.075 relating to issuers doing business with
Cuba.

          (m)  The Company agrees not to sell, offer for sale or solicit
offers to buy or otherwise negotiate in respect of any security (as defined
in the Act) that would be integrated with the sale of the Units in a manner
that would require the registration under the Act of the sale to the Initial
Purchaser or the Eligible Purchasers of the Units.

          (n)  The Company agrees to comply with all of the terms and
conditions of the Registration Rights Agreements, and all agreements set
forth in the representation letters of the Company to DTC relating to the
approval of the Units, Notes and Warrants by DTC for "book entry" transfer.

          (o)  The Company agrees that, prior to or contemporaneously with
any registration of the Notes pursuant to the Registration Rights Agreement,
or at such earlier time as may be so required, the Indenture shall be
qualified under the Trust Indenture Act of 1939, as amended (the "1939 Act").
The Company agrees to cause to be entered into any necessary supplemental
indentures in connection with such qualification.

          (p)  The Company shall, and shall use its best efforts to cause the
transfer agent with respect to the Units, Notes and Warrants to, refuse to
register any transfer of such securities sold pursuant to Rule 144A or
Regulation S if such transfer is not made in accordance with the provisions
of Rule 144A or Regulation S.

          (q)  The Company shall not, without the prior consent of the
Initial Purchaser, offer, sell, contract to sell or otherwise dispose of any
securities that are similar in quality or nature to the Notes offered hereby
(other than pursuant to an exchange offer for the Notes) for a period of 180
days after the Closing Date.

          5.   Representations and Warranties of the Company.  The Company
represents and warrants to the Initial Purchaser that:

          (a)  The Preliminary Offering Memorandum and Offering Memorandum
have been prepared by the Company for use by the Initial Purchaser in
connection with the Exempt Resales.  No order or decree preventing the use of
the Preliminary Offering Memorandum or the Offering Memorandum, or any order

the registration requirements of the Act, has been issued and no proceeding
for that purpose has commenced or is pending or, to the knowledge of the
Company, is contemplated.

          (b)  The Preliminary Offering Memorandum (as amended) and the
Offering Memorandum as of their respective dates, and the Offering Memorandum
as of the Closing Date, did not and will not, as the case may be, 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, except that this representation and warranty does not apply to
statements in or omissions from the Preliminary Offering Memorandum and
Offering Memorandum made in reliance upon and in conformity with information
relating to the Initial Purchaser or contained under the section entitled
"Private Placement" furnished to the Company in writing by or on behalf of
the Initial Purchaser expressly for use therein.

          (c)  The Indenture has been duly and validly authorized by the
Company and, upon its execution, delivery and performance by the Company and
assuming due authorization, execution, delivery and performance by the
Trustee, will be a valid, legal and binding agreement of the Company,
enforceable in accordance with its terms, except as enforcement thereof may
be limited by bankruptcy, insolvency, moratorium or other similar laws
affecting creditors' rights generally or equitable principles of general
applicability (whether such actions are deemed to be at law or in equity).
The Indenture conforms in all material respects to the description thereof in
the Offering Memorandum.  No qualification of the Indenture under the 1939
Act is required in connection with the offer and sale of the Notes
contemplated hereby or in connection with the Exempt Resales.  The Warrant

conforms in all material respects to the description thereof in the Offering
Memorandum.  The Registration Rights Agreements and this Purchase Agreement

policy considerations.

          (d)  The Pledge Agreements have been duly and validly authorized by
the Company and, upon their execution, delivery and performance by the
Company, and assuming due authorization, execution, delivery and performance
by the Collateral Agent, will be valid, legal and binding agreements of the

The Pledge Agreements conform in all material respects to the description
thereof in the Offering Memorandum.

          (e)  The Notes have been duly and validly authorized by the Company
and, when executed by the Company and authenticated by the Trustee in
accordance with the Indenture and delivered to the Initial Purchaser against
payment therefor in accordance with the terms hereof, (i) will have been
validly issued and delivered, and will constitute valid and binding
obligations of the Company entitled to the benefits of the Indenture and
enforceable in accordance with their terms, except as enforcement thereof may
be limited by bankruptcy, insolvency, moratorium or other similar laws
affecting the enforcement of creditors' rights generally or equitable
principles of general applicability (whether such actions are deemed to be at
law or in equity), and (ii) will conform in all material respects to the
description thereof in the Offering Memorandum.

          (f)  The Warrants have been duly authorized by the Company and,

be validly issued and, except as set forth in the Offering Memorandum, free
of any preemptive or similar rights and (ii) will conform in all material
respects to the description thereof in the Offering Memorandum.  The Company
has duly authorized and reserved a sufficient number of shares of Common
Stock for issuance upon the exercise of the Warrants.  All the outstanding
shares of capital stock of the Company have been duly authorized and validly
issued, are fully paid and nonassessable and, except as set forth in the
Offering Memorandum, are free of any preemptive or similar rights and were
issued and sold in compliance with all applicable Federal and state
securities laws.  The authorized capital stock of the Company conforms to the
description thereof in the Offering Memorandum.

          (g)  The Company is (i) a corporation duly organized, validly
existing and in good standing under the laws of the State of Delaware with
all requisite corporate power and authority to own, lease and operate its
properties, to conduct its business as described in the Offering Memorandum
and to enter into the Operative Documents and (ii) in good standing in each
jurisdiction or place where the nature of its properties or the conduct of
its business requires such registration or qualification, except where the
failure so to register or qualify does not have a material adverse effect on
the condition (financial or otherwise), business, prospects, properties, net
worth or results of operations of the Company and its Subsidiaries (as
hereinafter defined) taken as a whole (a "Material Adverse Effect").
<PAGE>

          (h)  All the Company's subsidiaries (as defined in the Act) are
referred to herein individually as a "Subsidiary" and collectively as the
"Subsidiaries."  Each Subsidiary is (i) a corporation duly organized, validly
existing and in good standing in the jurisdiction of its organization, with
all requisite corporate power and authority to own, lease and operate its
properties and to conduct its business as described in the Offering
Memorandum, and (ii) in good standing in each jurisdiction or place where the
nature of its properties or the conduct of its business requires such
registration or qualification, except where the failure so to register or
qualify or be in good standing does not have a Material Adverse Effect.  The
schedule delivered by the Company to the Initial Purchaser and dated the date
hereof sets forth a true and correct list of the percentage ownerships by the
Company of all of the entities in which it has an equity or other ownership
interest, either directly or through one or more Subsidiaries, and the entity
by which each such interest is held (the "Subsidiary Schedule").  All of such
interests consist solely of capital stock.  Except as set forth on the
Subsidiary Schedule, the Company does not, either directly or through one or
more Subsidiaries, hold any equity or other ownership interest of any entity
and the Company does not have any right to acquire any other equity or other
ownership interest of any entity.  Except as set forth in Schedule 2.3 to the
Agreement, dated as of March 20, 1995, by and among the Company and The SC
Fundamental Value Fund, L.P. and SC Fundamental Value BVI, Ltd. (the "Note

of the entities listed on the Subsidiary Schedule as being owned by the
Company, either directly or through one or more Subsidiaries, have been duly
authorized and validly issued, are fully paid and nonassessable, and are
owned by the Company or the Subsidiary indicated on the Subsidiary Schedule
free and clear of any lien, adverse claim, security interest or other
encumbrance; provided, however, that the Company represents and warrants that
liens, security interests or other encumbrances granted with respect to the
Capital Stock of the Subsidiaries in connection with the Note Purchase
Agreement shall be discharged simultaneously with the Closing.

          (i)  Neither the Company nor any Subsidiary holds a general
partnership interest in any Limited Partnership.

          (j)  There are no legal or governmental proceedings pending or, to
the knowledge of the Company, threatened against the Company or any of the
Subsidiaries, to which the Company or any of the Subsidiaries or any of their
respective properties is subject, that are not disclosed in the Offering
Memorandum and which, if adversely decided, could cause a Material Adverse
Effect or materially affect the issuance of the Units or the consummation of
the transactions contemplated by the Operative Documents.  There are no
material agreements, contracts, indentures, leases or other instruments that
are not described in the Offering Memorandum, the failure of which to
describe therein would constitute a material misstatement or the omission of
a material fact.  Except as described in the second paragraph under
"Business -- Employees" in the Offering Memorandum, neither the Company nor any
Subsidiary is involved in any strike, job action or labor dispute with any
group of employees and, to the Company's knowledge, no such action or dispute
is threatened.

          (k)  Neither the Company nor any of the Subsidiaries is (i) in
violation of its certificate or articles of incorporation or by-laws or other
organizational documents, or of any law, ordinance, administrative or
governmental rule or regulation applicable to the Company or any of the
Subsidiaries or of any decree of any court or governmental agency or body
having jurisdiction over the Company or any of the Subsidiaries, except where
any such violation or violations in the aggregate would not have a Material
Adverse Effect, or (ii) in default in any material respect in the performance
of any obligation, agreement or condition contained in any bond, debenture,
note or any other evidence of indebtedness or in any material agreement,
indenture, lease or other instrument to which the Company or any of the
Subsidiaries is a party or by which any of them or any of their respective
properties may be bound, except for such defaults which in the aggregate
would not have a Material Adverse Effect or as may be disclosed in the
Offering Memorandum.
<PAGE>

          (l)  Neither the issuance, offer, sale or delivery by the Company
of the Units, Notes, Warrants or shares of Common Stock issuable upon the
exercise of the Warrants, the execution, delivery or performance of the
Operative Documents by the Company, nor the consummation by the Company of
the transactions contemplated hereby or thereby, (i) requires any consent,
approval, authorization or other order of, or registration or filing with,
any court, regulatory body, administrative agency or other governmental body,
agency or official (except such as may be required in connection with the
registration under the Act of the Notes or the shares of Common Stock
issuable upon the exercise of Warrants in accordance with the applicable
Registration Rights Agreement, the qualification of the Indenture under the
1939 Act, compliance with the securities or "blue sky" laws of various
jurisdictions and except as may be required under any applicable
telecommunications law, in the last such case to the extent described in the
Offering Memorandum), or conflicts or will conflict with or constitutes or
will constitute a breach of, or a default under, the certificate or articles
of incorporation or bylaws, or other organizational documents, of the Company
or any of the Subsidiaries or (ii) conflicts or will conflict with or
constitutes or will constitute a breach of, or a default under any material
agreement, indenture, lease or other instrument to which the Company or any
of the Subsidiaries is a party or by which any of them or any of their
respective properties may be bound, or violates or will violate any statute,
law, regulation or filing or judgment, injunction, order or decree applicable
to the Company or any of the Subsidiaries or any of their respective
properties, or will result in the creation or imposition of any lien, charge
or encumbrance upon any property or assets of the Company or any of the
Subsidiaries pursuant to the terms of any agreement or instrument to which
any of them is a party or by which any of them may be bound or to which any
of the property or assets of any of them is subject.

          (m)  The accountants, Coopers & Lybrand, who have certified or
shall certify the financial statements included as part of the Offering
Memorandum (or any amendment or supplement thereto) are independent public
accountants under Rule 101 of the AICPA's Code of Professional Conduct and
its interpretation and rulings.

          (n)  The financial statements (historical and pro forma), together
with related notes forming part of the Offering Memorandum, present fairly in
all material respects the consolidated financial position, results of
operations and changes in stockholders* equity and cash flows of the Company
and the Subsidiaries on the basis stated in the Offering Memorandum at the
respective dates or for the respective periods to which they apply.  Such
financial statements and related notes have been prepared in accordance with
generally accepted accounting principles consistently applied throughout the
periods involved, except as disclosed therein.  With respect to the
assumptions used in preparing the pro forma financial information and related
notes included in the Offering Memorandum, the Company has a reasonable basis
for such assumptions.  The other financial and statistical information and
data set forth in the Offering Memorandum is accurately presented and, to the
extent such information and data is derived from the financial books and
records of the Company, is prepared on a basis consistent with such financial
statements and the books and records of the Company.

          (o)  Except as disclosed in the Offering Memorandum, subsequent to
the date as of which such information is given in the Offering Memorandum,
(i) neither the Company nor any of the Subsidiaries has incurred any
liability or obligation, direct or contingent, or entered into any
transaction not in the ordinary course of business, that is material to the
Company and the Subsidiaries taken as a whole and (ii) there has not been
(A) any material change in the capital stock or material increase in the
short-term or long-term debt of the Company or any of the Subsidiaries or
(B) any Material Adverse Change, or any development of which the Company knew
or should have known and which involves or which could reasonably be expected
to involve a prospective Material Adverse Change.
<PAGE>

          (p)  Each of the Company and the Subsidiaries has good and
marketable title to all property (real and personal), other than intellectual
property (which is addressed in (w) below) and other than capital stock
(which is addressed in (h) above), described in the Offering Memorandum as
being owned by it, free and clear of all liens, claims, security interests or
other encumbrances except such as are described in the Offering Memorandum
(including, without limitation, any security interest pertaining to the cash
account pertaining to the Defeased Notes), any Incorporated Document or
exhibit thereto or that do not materially impair or are not expected to
materially impair the ability of the Company to use any such property, and
except for the lien on the license granted by the FCC having a call sign of
WNKL 343, and all the property described in the Offering Memorandum as being
held under lease by each of the Company and the Subsidiaries is held by it
under valid, subsisting and enforceable leases, with only such exceptions as
in the aggregate are not materially burdensome and do not interfere in any
material respect with the conduct of the business of the Company and the
Subsidiaries taken as a whole.

          (q)  Except as permitted by the Act, the Company has not
distributed and, prior to the later to occur of the Closing Date and
completion of the distribution of the Units, will not distribute any offering
material in connection with the offering and sale of the Units other than the
Preliminary Offering Memorandum and the Offering Memorandum, respectively.

          (r)  Each of the Company and the Subsidiaries have such permits,
licenses, franchises, and other approvals or authorizations of governmental
or regulatory authorities, including, without limitation, all waivers,
licenses and authorizations to develop, implement and operate wireless
telecommunications systems as described, and in such manner as is described,
in the Offering Memorandum (collectively, "Permits"), as are necessary under
applicable law to own their respective properties and to conduct their
respective business in the manner described in the Offering Memorandum,
except to the extent otherwise provided therein.  The Company and each of the
Subsidiaries have fulfilled and performed in all material respects all of
their respective material obligations with respect to the Permits and no
event has occurred which allows, or after notice or lapse of time would
allow, revocation or termination thereof or result in any other material
impairment of the rights of the holder of any such Permit, subject in each
case to such qualification as may be set forth in the Offering Memorandum.
Except as described in the Offering Memorandum, (i) there are no legal or
governmental proceedings pending or, to the knowledge of the Company,
threatened with respect to any of the Permits and (ii) neither the Company
nor any Subsidiary is in default under any Permit.  All of the management
agreements pertaining to the licenses listed on Annex 1 to the draft opinion
of Skadden, Arps, Slate, Meagher & Flom, special counsel to the Company for

against the parties thereto in accordance with their terms, except as (i)
enforcement may be limited by bankruptcy, insolvency, moratorium or other
similar laws affecting creditors' rights and (ii) the availability of
equitable remedies may be limited by equitable principles of general
applicability (whether such actions are deemed to be at law or in equity).
All permits, licenses, franchises and other approvals or authorizations of
applicable telecommunications authorities, including, without limitation, all
waivers, licenses and authorizations to develop, implement and operate
wireless telecommunications systems (the "Regulatory Permits"), to the extent
held by the Company or a Subsidiary thereof, are held directly by Geotek
Acquisition Corp., Geotek Subsidiary Industries, Inc., MetroNet Systems,
Inc., Power Spectrum, Inc., USI Venture Corp., National Band Three Limited or

their direct or indirect wholly-owned Subsidiaries, except that, in the case
of Geotek Germany, such Regulatory Permits are held by DBF Bundelfunk GmbH &
Co. K.G. ("DBF") and Preussag Bundelfunk GmbH ("Preussag").  All direct and
indirect interests (whether actual or contingent) of the Company and its
Subsidiaries in any Regulatory Permits, to the extent held by third parties
(including, without limitation, any rights pursuant to management agreements
or options), are held directly by the Pledged Companies or their wholly-owned
<PAGE>

Subsidiaries, except that, in the case of Geotek Germany, such interests are
held by DBF and Preussag.  Neither the Company nor any Subsidiary thereof,
other than the Pledged Companies and their direct or indirect wholly-owned
Subsidiaries, has any right to acquire, is seeking to acquire or is otherwise
in the process of acquiring any Regulatory Permit or any actual or contingent
right therein, other than any Regulatory Permit issued pursuant to the laws

          (s)  The Company maintains a system of internal accounting controls
sufficient to provide reasonable assurances that (i) transactions are
executed in accordance with management's general or specific authorization,
(ii) transactions are recorded as necessary to permit preparation of
financial statements in conformity with generally accepted accounting
principles and to maintain accountability for assets, (iii) access to assets
is permitted only in accordance with management's general or specific

with existing assets at reasonable intervals and appropriate action is taken
with respect to any differences.

          (t)  Neither the Company nor any of the Subsidiaries nor, to the
Company's knowledge, any employee or agent of the Company or any Subsidiary
has made any payment of funds of the Company or any Subsidiary or received or
retained any funds in violation of any law, rule or regulation, which
violation would have a Material Adverse Effect.

          (u)  The Company and each of the Subsidiaries have filed all tax
returns required to be filed, which returns are true and correct in all
material respects, and neither the Company nor any Subsidiary is in default
in the payment of any taxes which were payable pursuant to said returns or
any assessments with respect thereto, except where the failure to file such
returns and make such payments would not have a Material Adverse Effect.

          (v)  Except as described in the Offering Memorandum, no holder of
any security of the Company (other than holders of the Notes and the
Warrants) has any right to request or demand registration of shares of Common
Stock or any other security of the Company because of the consummation of the
transactions contemplated by this Agreement or the Registration Rights
Agreements.  Except as described in or contemplated by the Operative
Documents or the Offering Memorandum or as described in writing to the
Initial Purchaser, there are no outstanding options, warrants or other rights
calling for the issuance of, and there are no commitments, plans or
arrangements to issue, any shares of capital stock of the Company or any
security convertible into or exchangeable or exercisable for capital stock of
the Company.

          (w)  The Company and the Subsidiaries own or possess all patents,
trademarks, trademark registration, service marks, service mark
registrations, trade names, copyrights, licenses, inventions, trade secrets
and rights described in the Offering Memorandum as being owned by any of them
or, except as described in the Offering Memorandum, necessary for the current
and contemplated conduct of their respective businesses as described in the
Offering Memorandum (including, without limitation, all such patents,
trademarks and other rights necessary to develop, implement and operate
wireless telecommunications systems as described, and in such markets as are
described, in the Offering Memorandum).  Except as described in the Offering
Memorandum, none of the officers of the Company is aware of any claim to the
contrary or any challenge by any other person to the rights of the Company
and the Subsidiaries with respect to any of the foregoing.

          (x)  Upon the possession by the Collateral Agent of the
certificates representing the Collateral, in the case of the Pledged
Companies (as defined in the Preliminary Offering Memorandum, as amended)
organized under the laws of a jurisdiction within the United States, or the
transfer on the share registry of the applicable Pledged Company to the
Collateral Agent of the shares of such Pledged Company, in the case of the
Pledged Companies organized under the laws of the United Kingdom or Germany,
and assuming that the Collateral Agent complies with any applicable notice or
registration provisions applicable to it, the security interests created in
favor of the Collateral Agent under the Pledge Agreements with respect to the
Collateral will constitute perfected security interests in such Collateral
and proceeds thereof, and no other filings, registration or recordings are
required in order to perfect the security interests in such Collateral and
proceeds under the Pledge Agreements.
<PAGE>

          (y)  The Company is not and, upon the sale of the Units to be
issued and sold thereby in accordance herewith and the application of the net
proceeds to the Company of such sale as described in the Offering Memorandum
under the caption "Use of Proceeds," will not be an "investment company" or
an entity "controlled" by an "investment company" within the meaning of the
Investment Company Act.

          (z)  When the Units, Notes and Warrants are issued and delivered
pursuant to this Agreement, such Units, Notes and Warrants will not be of the
same class (within the meaning of Rule 144A(d)(3) under the Act) as any
security of the Company that is listed on a national securities exchange
registered under Section 6 of the Exchange Act or that is quoted in a United
States automated inter dealer quotation system.

          (aa) Neither the Company nor any affiliate (as defined in Rule
501(b) of Regulation D) of the Company has directly, or through any agent
(provided that no representation is made as to the Initial Purchaser or any
person acting on its behalf), (i) sold, offered for sale, solicited offers to
buy or otherwise negotiated in respect of, any security (as defined in the
Act) which is or will be integrated with the offering and sale of the Units
in a manner that would require the registration of the Units, Notes or
Warrants under the Act or (ii) engaged in any form of general solicitation or
general advertising (within the meaning of Regulation D) in connection with
the offering of the Units.

          (ab) The Company is not required to deliver the information
specified in Rule 144A(d)(4) in connection with the offering and resale of
the Units, Notes or Warrants by the Initial Purchaser.

          (ac) Assuming (i) that the representations and warranties in
Section 2 hereof are true, (ii) that the Initial Purchaser complies with the
covenants set forth in Section 2 hereof and (iii) that each person to whom
the Initial Purchaser offers, sells or delivers the Units is a Qualified
Institutional Buyer, an Accredited Investor or a person other than a U.S.
person outside the United States to whom offers and sales are being made in
reliance on Regulation S under the Act, the purchase and sale of the Units
pursuant hereto (including the Initial Purchaser's proposed offering of the
Units on the terms and in the manner set forth in the Offering Memorandum and
Section 2 hereof) is exempt from the registration requirements of the Act.
None of the Company, its Subsidiaries or affiliates or any person acting on
its or their behalf (other than the Initial Purchaser) has engaged in any
directed selling efforts (as that term is defined in Regulation S under the
Act) with respect to the Units and the Company, its Subsidiaries or
affiliates and any person acting on its or their behalf (other than the
Initial Purchaser) have complied with the offering restrictions requirement
of Regulation S.

          (ad) The execution and delivery of this Agreement, the other
Operative Documents and the sale of the Units to the Initial Purchaser or by
the Initial Purchaser to Eligible Purchasers will not involve any prohibited
transaction within the meaning of Section 406 of ERISA or Section 4975 of the
Code.  The representation made by the Company in the preceding sentence is
made in reliance upon and subject to the accuracy of, and compliance with,
the representations and covenants made or deemed made by the Eligible
Purchasers as set forth in the Offering Memorandum under the section entitled
"Notice to Investors."

          (ae) The Company is not required to obtain stockholder consent or
approval pursuant to the rules of The Nasdaq National Market, the Pacific
Stock Exchange or any other exchange or trading facility in connection with
the offering and sale of the Units.

          6.   Indemnification and Contribution.  (a)  The Company agrees to
indemnify and hold harmless the Initial Purchaser and each person, if any,
who controls the Initial Purchaser within the meaning of Section 15 of the
Act or Section 20 of the Exchange Act (each a "Purchaser Indemnitee") from
and against any and all losses, claims, damages, liabilities and expenses
(including, without limitation, any legal or other expenses reasonably
incurred by the Purchaser Indemnitee in connection with defending or
investigating any such action or claim) arising out of or based upon any
untrue statement or alleged untrue statement of a material fact contained in
the Preliminary Offering Memorandum or Offering Memorandum or in any
<PAGE>

amendment or supplement thereto, or arising out of or based upon any omission
or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading, except insofar as
such losses, claims, damages, liabilities or expenses arise out of or are
based upon any untrue statement or omission or alleged untrue statement or
omission which has been made therein or omitted therefrom in reliance upon
and in conformity with the information relating to the Initial Purchaser
furnished in writing to the Company by or on behalf of the Initial Purchaser
expressly for use in connection therewith; provided, however, that the
indemnification provided for in this paragraph (a) with respect to the
Preliminary Offering Memorandum shall not inure to the benefit of the
applicable Purchaser Indemnitee on account of any such loss, claim, damage,
liability or expense arising from the sale of the Units by the Initial
Purchaser to any person if the untrue statement or alleged untrue statement
or omission or alleged omission of a material fact contained in the
Preliminary Offering Memorandum was corrected in the Offering Memorandum and
the Initial Purchaser sold Units to that person without sending or giving at
or prior to the written confirmation of such sale, a copy of the Offering
Memorandum (as then amended or supplemented) if the Company has previously
furnished sufficient copies thereof to the Initial Purchaser on a timely
basis.  The indemnification obligation of the Company set forth in this
paragraph (a) shall be in addition to any liability which the Company may
otherwise have, including, without limitation, any liability for any breach
of any representation, warranty or covenant contained in this Agreement.

          (b)  If any action, suit or proceeding shall be brought against any
Purchaser Indemnitee in respect of which indemnification may be sought
against the Company, such Purchaser Indemnitee shall promptly notify the
parties against whom indemnification is being sought (the "indemnifying
parties"), and such indemnifying parties shall assume the defense thereof,
including the employment of counsel and payment of all fees and expenses.
Such Purchaser Indemnitee 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 Purchaser Indemnitee unless (i) the indemnifying parties have agreed in
writing to pay such fees and expenses, (ii) the indemnifying parties have
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 Purchaser Indemnitee and the indemnifying parties and such
Purchaser Indemnitee shall have been advised by its counsel that
representation of such Purchaser Indemnitee and any indemnifying party 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 indemnifying party shall not have the right to assume
the defense of such action, suit or proceeding on behalf of the Purchaser
Indemnitee).  It is understood, however, that the indemnifying parties 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 the Initial
Purchaser and any other Purchaser Indemnitee not having actual or potential
differing interests with the Initial Purchaser or among themselves, which
firm shall be designated in writing by the Initial Purchaser.  The
indemnifying parties shall not be liable for any settlement of any such
action, suit or proceeding effected without their 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 indemnifying parties
agree to indemnify and hold harmless the Purchaser Indemnitee, to the extent
provided in paragraph (a), from and against any loss, claim, damage,
liability or expense by reason of such settlement or judgment.
<PAGE>

          (c)  The Initial Purchaser agrees to indemnify and hold harmless
the Company, and its directors and officers, and any person who controls the
Company within the meaning of Section 15 of the Act or Section 20 of the
Exchange Act (each a "Company Indemnitee") to the same extent as the
indemnity from the Company to the Initial Purchaser set forth in
paragraph (a) hereof, but only with respect to information relating to the
Initial Purchaser furnished in writing by or on behalf of the Initial
Purchaser expressly for use in the Preliminary Offering Memorandum or
Offering Memorandum or any amendment or supplement thereto.  If any action,
suit or proceeding shall be brought against any Company Indemnitee based on
the Preliminary Offering Memorandum or Offering Memorandum, or any amendment
or supplement thereto, and in respect of which indemnity may be sought
against the Initial Purchaser pursuant to this paragraph (c), the Initial
Purchaser 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
the Initial Purchaser 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 the Initial Purchaser's expense), and
each Company Indemnitee shall have the rights and duties given to the Initial
Purchaser by paragraph (b) above.  The indemnification obligation of the
Initial Purchaser set forth in this paragraph (c) shall be in addition to any
liability which the Initial Purchaser may otherwise have, including without
limitation, any liability for any breach of any representation, warranty or
covenant contained in this Agreement.

          (d)  If the indemnification provided for in this Section 6 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 Initial Purchaser on the
other hand from the offering of the Units 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 Initial Purchaser 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 Initial
Purchaser on the other shall be deemed to be in the same proportion as the
total net proceeds from the offering (before deducting expenses and after
discounts and commissions received by the Initial Purchaser) received by the
Company bear to the total discounts and commissions received by the Initial
Purchaser, in each case as set forth in the table on the cover page of the
Offering Memorandum; provided that, in the event that the Initial Purchaser
shall have purchased any Additional Units hereunder, any determination of the
relative benefits received by the Company or the Initial Purchaser from the
offering of the Units shall include the net proceeds (before deducting
expenses and after discounts and commissions received by the Initial
Purchaser) received by the Company, and the discounts and commissions
received by the Initial Purchaser, from the sale of such Additional Units, in
each case computed on the basis of the respective amounts set forth in the
notes to the table on the cover page of the Offering Memorandum.  The
relative fault of the Company on the one hand and the Initial Purchaser 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 Initial Purchaser on the
other hand and the parties' relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission.
<PAGE>

          (e)  The Company and the Initial Purchaser agree that it would not
be just and equitable if contribution pursuant to this Section 6 were
determined by a pro rata allocation 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 6, the Initial Purchaser shall not be required to contribute any
amount in excess of the amount by which the total price of the Units resold
by it in the initial placement of such Units exceeds the amount of any
damages which the Initial Purchaser has 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
remedies provided for in this Section 6 are not exclusive and shall not limit
any rights or remedies that may otherwise be available to any indemnified
party at law or in equity.

          (f)  Any losses, claims, damages, liabilities or expenses for which
an indemnified party is entitled to indemnification or contribution under
this Section 6 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 6 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 Purchaser Indemnitee or any Company
Indemnitee, (ii) acceptance of any Units and payment therefor hereunder and
(iii) any termination of this Agreement.  A successor to any Purchaser
Indemnitee, or to any Company Indemnitee shall be entitled to the benefits of
the indemnity, contribution and reimbursement agreements contained in this
Section 6.

          (g)  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.

          7.   Conditions of the Initial Purchaser's Obligations.  The
obligations of the Initial Purchaser to purchase the Firm Units hereunder are
subject to the following conditions:

          (a)  At the time of execution of this Agreement and on the Closing

have been commenced or shall be pending or, to the knowledge of the Company,
be contemplated.  No stop order suspending the sale of the Units in any

which, in the opinion of the Initial Purchaser, would materially adversely
affect the market for the Units or (ii) any event or development relating to
or involving the Company, any Subsidiary or any officer or director of the
Company which makes any statement made in the Offering Memorandum untrue or

and its counsel, requires the making of any addition to or change in the
<PAGE>

Offering Memorandum in order to state a material fact required by any law to
be stated therein or necessary in order to make the statements therein not
misleading, if amending or supplementing the Offering Memorandum to reflect
such event or development would, in the opinion of the Initial Purchaser,
materially adversely affect the market for the Units or make it impracticable
to market the Units on the terms and in the manner contemplated in the
Offering Memorandum.

been, since the respective dates as of which information is given in the

representations and warranties of the Company contained in this Agreement

          (g)  The Company shall not have failed at or prior to the Closing

downgrading its rating assigned to any class of securities of the Company or
(ii) it is reviewing its ratings assigned to any class of securities of the
Company with a view to possible downgrading, or with negative implications,

the other Operative Documents and the Collateral shall have been delivered to
the Collateral Agent pursuant to the terms of the Pledge Agreements.

          (k)  The Company shall have furnished or caused to be furnished to
the Initial Purchaser such further certificates and documents as the Initial
Purchaser shall have reasonably requested.

          (l)  Simultaneously with the consummation of the transactions

satisfactory in form and substance to the Initial Purchaser and counsel for
the Initial Purchaser.

          Any certificate or document signed by any officer of the Company

Purchaser, shall be deemed a representation and warranty by the Company to
the Initial Purchaser as to the statements made therein.

          The obligations of the Initial Purchaser to purchase any Additional
Notes hereunder are subject to the satisfaction on and as of any Option
Closing Date of the conditions set forth in this Section 7, except that, if
any Option Closing Date is other than the Closing Date, the certificates,
opinions and letters referred to in paragraphs (c) through (f) and paragraph
(k) shall be dated the Option Closing Date in question and the opinions
called for by paragraphs (c) and (d) shall be revised to reflect the sale of
Additional Units.

          8.   Expenses.  The Company agrees to pay the following costs and

          9.   Effective Date of Agreement.  This Agreement shall become
effective upon the execution and delivery hereof by all the parties hereto.
Until such time as this Agreement shall have become effective, to the extent
that a party hereto, but not the other party hereto, has executed and
delivered this Agreement, such party executing and delivering this Agreement
may rescind such execution and delivery by written notice to the other party
hereto.

banking activities in New York shall have been declared by either Federal or
state authorities or (iii) there shall have occurred any outbreak or
escalation of hostilities or other international or domestic calamity, crisis

on the financial markets of the United States is such as to make it, in the
judgment of the Initial Purchaser, impracticable or inadvisable to commence
or continue the offering of the Units on the terms set forth on the cover
page of the Offering Memorandum or to enforce contracts for the resale of the
Units by the Initial Purchaser.  Notice of such termination may be given to
the Company by telegram, telecopy or telephone and shall be subsequently
confirmed by letter.

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 the Initial Purchaser of any of
the Notes in his status as such purchaser.

          Neither party hereto may assign any of its rights or delegate any
of its obligations without the consent of the other party hereto.

          The headings of the sections of this Agreement have been inserted
for convenience of reference only and shall not be deemed a part of this
Agreement.

          13.  Entire Agreement.  This Agreement constitutes the entire
agreement between the parties with respect to the subject matter hereof and
supersedes all prior agreements, understandings and negotiations, both
written and oral, between the parties with respect to the subject matter of

     amount set forth below for such Semi-Annual Accrual Date:

                                          Accreted
          Semi-Annual Accrual Date         Value
          ------------------------        --------

          July 15, 2000                  1,000.00

          (b)  if the Specified Date occurs before the first Semi-Annual
     Accrual Date, the Accreted Value will equal the sum of (i) the original
     issue price of the Securities and (ii) an amount equal to the product of
     (A) the Accreted Value for the first Semi-Annual Accrual Date less the
     original issue price multiplied by (B) a fraction, the numerator of
     which is the number of days from the Issue Date to the Specified Date,
     using a 360-day year of twelve 30-day months, and the denominator of
     which is the number of days elapsed from the Issue Date to the first
     Semi-Annual Accrual Date, using a 360-day year of twelve 30-day months;

     for the immediately following Semi-Annual Accrual Date less the Accreted
     Value for the immediately preceding Semi-Annual Accrual Date multiplied
     by (B) a fraction, the numerator of which is the number of days from the
     immediately preceding Semi-Annual Accrual Date to the Specified Date,
     using a 360-day year of twelve 30-day months, and the denominator of
     which is 180; or

          (d)  if the Specified Date occurs after the last Semi-Annual
     Accrual Date, the Accreted Value will equal $1,000.

          In each case, the calculation of Accreted Value on such Specified
Date shall be delivered to the Trustee by the Company.

legend, subject to Section 2.08(f):

THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE U.S SECURITIES ACT OF 1933,
AS AMENDED (THE "SECURITIES ACT"), AND, ACCORDINGLY, MAY NOT BE OFFERED OR
SOLD WITHIN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, U.S.
PERSONS EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE.  BY ITS ACQUISITION
HEREOF THE HOLDER (1) REPRESENTS THAT (A) IT IS A "QUALIFIED INSTITUTIONAL
BUYER" (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) OR (B) IT IS AN
INSTITUTIONAL "ACCREDITED INVESTOR" (AS DEFINED IN RULE 501(a)(1), (2), (3)
OR (7) OF REGULATION D UNDER THE SECURITIES ACT) (AN "INSTITUTIONAL
ACCREDITED INVESTOR") OR (C) IT IS NOT A U.S. PERSON AND IS ACQUIRING THIS
SECURITY IN AN OFFSHORE TRANSACTION IN COMPLIANCE WITH REGULATION S UNDER THE
SECURITIES ACT, (2) AGREES THAT IT WILL NOT, WITHIN THREE YEARS AFTER THE
LATER OF THE ORIGINAL ISSUANCE OF THIS SECURITY OR THE LAST DATE ON WHICH
THIS SECURITY WAS HELD BY THE COMPANY OR ANY AFFILIATE OF THE COMPANY, RESELL
OR OTHERWISE TRANSFER THIS SECURITY EXCEPT (A) TO THE COMPANY OR ANY
SUBSIDIARY THEREOF (B) INSIDE THE UNITED STATES TO A QUALIFIED INSTITUTIONAL
BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, (C) INSIDE THE
UNITED STATES TO AN INSTITUTIONAL ACCREDITED INVESTOR THAT, PRIOR TO SUCH
TRANSFER, FURNISHES TO THE TRUSTEE A SIGNED LETTER CONTAINING CERTAIN
REPRESENTATIONS AND AGREEMENTS RELATING TO THE RESTRICTIONS ON TRANSFER OF
THIS SECURITY (THE FORM OF WHICH LETTER CAN BE OBTAINED FROM THE TRUSTEE) AND
IF SUCH TRANSFER IS IN RESPECT OF AN ACCRETED VALUE OF NOTES AT THE TIME OF
TRANSFER OF LESS THAN $250,000, AN OPINION OF COUNSEL ACCEPTABLE TO THE
COMPANY THAT SUCH TRANSFER IS IN COMPLIANCE WITH THE SECURITIES ACT,
(D) OUTSIDE THE UNITED STATES IN AN OFFSHORE TRANSACTION IN COMPLIANCE WITH
RULE 904 UNDER THE SECURITIES ACT, (E) PURSUANT TO THE EXEMPTION FROM
REGISTRATION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT (IF AVAILABLE) OR
(F) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT
AND (3) AGREES THAT IT WILL DELIVER TO EACH PERSON TO WHOM THIS SECURITY IS
TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND.  IN
CONNECTION WITH ANY TRANSFER OF THIS SECURITY WITHIN THREE YEARS AFTER THE
LATER OF THE ORIGINAL ISSUANCE OF THE SECURITY OR THE LAST DATE ON WHICH THIS
SECURITY WAS HELD BY THE COMPANY OR AN AFFILIATE OF THE COMPANY, THE HOLDER
MUST CHECK THE APPROPRIATE BOX SET FORTH ON THE REVERSE HEREOF RELATING TO
<PAGE>

THE MANNER OF SUCH TRANSFER AND SUBMIT THIS CERTIFICATE TO THE TRUSTEE.  IF
THE PROPOSED TRANSFEREE IS AN INSTITUTIONAL ACCREDITED INVESTOR, THE HOLDER
MUST, PRIOR TO SUCH TRANSFER, FURNISH TO THE TRUSTEE AND THE COMPANY SUCH
CERTIFICATIONS, LEGAL OPINIONS OR OTHER INFORMATION AS EITHER OF THEM MAY
REASONABLY REQUIRE TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN
EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION
REQUIREMENTS OF THE SECURITIES ACT.  AS USED HEREIN, THE TERMS "OFFSHORE
TRANSACTION," "UNITED STATES" AND "U.S. PERSON" HAVE THE MEANINGS GIVEN TO
THEM BY REGULATION S UNDER THE SECURITIES ACT.  THE INDENTURE CONTAINS A
PROVISION REQUIRING THE TRUSTEE TO REFUSE TO REGISTER ANY TRANSFER OF THIS
SECURITY IN VIOLATION OF THE FOREGOING RESTRICTIONS.

          (b)  Each Global Security shall also bear the following legend:
UNLESS THIS NOTE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE
DEPOSITORY TRUST COMPANY TO THE COMPANY OR ITS AGENT FOR REGISTRATION OF
TRANSFER, EXCHANGE OR PAYMENT, AND ANY NOTE ISSUED IS REGISTERED IN THE NAME
OF CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED
REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY OR SUCH OTHER REPRESENTATIVE
OF THE DEPOSITORY TRUST COMPANY OR SUCH OTHER NAME AS IS REQUESTED BY AN
AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY (AND ANY PAYMENT
HEREON IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN
AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY), ANY TRANSFER,
PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS
WRONGFUL SINCE THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST
HEREIN.

TRANSFERS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS IN WHOLE, BUT
NOT IN PART, TO NOMINEES OF CEDE & CO. OR TO A SUCCESSOR THEREOF OR SUCH
SUCCESSOR'S NOMINEE AND TRANSFERS OF PORTIONS OF THIS GLOBAL SECURITY SHALL
BE LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE RESTRICTIONS SET FORTH IN
SECTION 2.08 OF THE INDENTURE.

          (c)  Prior to the close of business upon the earliest to occur of
(i) January 30, 1996, (ii) the commencement of the Exchange Offer, (iii) such
earlier date as the Initial Purchaser may determine and specify to the
Trustee in writing, and (iv) in the event of a Change of Control, the date
the Company mails notice thereof to the Holders (the "Separation Date"), each
Series A Note shall bear the following legend:

THIS NOTE IS INITIALLY ISSUED AS PART OF AN ISSUANCE OF UNITS (THE "UNITS"),

A PRINCIPAL AMOUNT AT MATURITY OF $1,000 (THE "NOTES") OF GEOTEK

WRITING, AND (iv) IN THE EVENT OF A CHANGE OF CONTROL (AS DEFINED IN THE
INDENTURE), THE DATE THE COMPANY MAILS NOTICE THEREOF TO HOLDERS OF THE
NOTES,  THE NOTES EVIDENCED BY THIS CERTIFICATE MAY NOT BE TRANSFERRED OR
EXCHANGED SEPARATELY FROM, BUT MAY BE TRANSFERRED OR EXCHANGED ONLY TOGETHER
WITH, THE WARRANTS AND, DURING SUCH TIME, THE NOTES WILL EFFECTIVELY BE
SUBJECT TO ANY TRANSFER RESTRICTIONS APPLICABLE TO THE WARRANTS.

          2.03.   Execution, Authentication and Denominations.  Two Officers
shall execute the Securities for the Company by facsimile or manual signature
in the name and on behalf of the Company.  The seal of the Company, if any,
shall be reproduced on the Securities.

          If an Officer whose signature is on a Security no longer holds that
office at the time the Trustee or authenticating agent authenticates the
Security, the Security shall be valid nevertheless.

          A Security shall not be valid until the Trustee or authenticating
agent manually signs the certificate of authentication on the Security.  The
signature shall be conclusive evidence that the Security has been
authenticated under this Indenture.
<PAGE>

          The Trustee or an authenticating agent shall upon receipt of a
Company Order authenticate for original issue Series A Notes in the aggregate
principal amount at maturity not to exceed $207,000,000 (subject to any
increase as provided for in Section 2.01 hereof).  The Trustee or an
authenticating agent shall upon receipt of a Company Order authenticate for
original issue Series B Notes in an aggregate principal amount at maturity
not to exceed $207,000,000 (subject to any increase as provided for in
Section 2.01 hereof); provided that such Series B Notes shall be issuable
only upon the valid surrender for cancellation of Series A Notes of a like
aggregate principal amount at maturity in accordance with the Exchange Offer.
In each case, the Trustee shall be entitled to receive any Officers'
Certificate and any Opinion of Counsel of the Company that it may reasonably
request in connection with such authentication of Securities, including,
without limitation, in the case of the original issuance of Series B Notes,
an Opinion of Counsel dated the date thereof substantially to the effect set
forth in Exhibit D hereto.  Such Company Order shall specify the amount of
Securities to be authenticated and the date on which the original issue of
Securities is to be authenticated.  The aggregate principal amount at
maturity of Securities outstanding at any time may not exceed the amount set
forth above except for Securities authenticated and delivered upon
registration of transfer of, or in exchange for, or in lieu of, other
Securities pursuant to Section 2.06, 2.09, 2.10 or 2.11.

          The Trustee may appoint an authenticating agent to authenticate
Securities.  An authenticating agent may authenticate Securities whenever the
Trustee may do so. Each reference in this Indenture to authentication by the
Trustee includes authentication by such authenticating agent.  An
authenticating agent has the same rights as an Agent to deal with the Company
or an Affiliate of the Company.  The Trustee shall not be liable for any act
or failure of the authenticating agent to perform any duty either required
herein or authored herein to be performed by such person in accordance with
this Indenture.

          The Securities shall be issuable only in registered form without
coupons and only in denominations of $1,000 in principal amount at maturity
and any integral multiple of $1,000 in excess thereof.

          2.04.   Registrar and Paying Agent.  The Company shall maintain an
office or agency where Securities may be presented for registration of
transfer or for exchange (the "Registrar"), an office or agency where
Securities may be presented for payment (the "Paying Agent") and an office or
agency where notices and demands to or upon the Company in respect of the
Securities and this Indenture may be served, which shall be in the Borough of
Manhattan, The City of New York.  The Company shall cause the Registrar to
keep a register of the Securities and of their transfer and exchange (the
"Security Register").  The Company may have one or more co-Registrars and one
or more additional Paying Agents. Unless the context otherwise requires, the
terms "Registrar" and "Paying Agent" shall apply to any co-Registrar and
additional Paying Agent, respectively.

          The Company shall enter into an appropriate agency agreement with
any Agent not a party to this Indenture.  The agreement shall implement the
provisions of this Indenture that relate to such Agent.  The Company shall
give prompt written notice to the Trustee of the name and address of any such
Agent and any change in the address of such Agent.  If the Company fails to
maintain a Registrar, Paying Agent and/or agent for service of notices and
demands, the Trustee shall, upon written notice thereof from the Company, act
as such Registrar, Paying Agent and/or agent for service of notices and
demands for so long as such failure shall continue.  The Company may remove
any Agent upon written notice to such Agent and the Trustee; provided that no
such removal shall become effective until (i) the acceptance of an
appointment by a successor Agent to such Agent as evidenced by an appropriate
agency agreement entered into by the Company and such successor Agent and
delivered to the Trustee or (ii) notification to the Trustee that the Trustee
shall serve as such Agent until the appointment of a successor Agent in
accordance with clause (i) of this proviso.  The Company, any Subsidiary of
the Company, or any Affiliate of any of them may act as Paying Agent,
Registrar or co-Registrar, and/or agent for service of notice and demands;
provided, however, that neither the Company, any Subsidiary of the Company
nor any Affiliate of any of them shall act as Paying Agent in connection with
the defeasance of the Securities or the discharge of this Indenture under
Article Eight.
<PAGE>

          The Company initially appoints the Trustee as Registrar, Paying
Agent, authenticating agent and agent for service of notice and demands.  If,
at any time, the Trustee is not the Registrar, the Registrar shall make
available to the Trustee, on or before each Interest Payment Date and at such
other times as the Trustee may reasonably request, the names and addresses of
the Holders as they appear in the Security Register.

          2.05.   Paying Agent to Hold Money in Trust.  Not later than each
due date of the principal, premium, if any, and interest on any Securities,
the Company shall deposit with the Paying Agent money in immediately
available funds sufficient to pay such principal, premium, if any, and
interest so becoming due.  The Company shall require each Paying Agent other
than the Trustee to agree in writing that such Paying Agent shall hold in
trust for the benefit of the Holders or the Trustee all money held by the
Paying Agent for the payment of principal of, premium, if any, and interest
on the Securities (whether such money has been paid to it by the Company or
any other obligor on the Securities), and that such Paying Agent shall
promptly notify the Trustee of any default by the Company (or any other
obligor on the Securities) in making any such payment.  The Company at any
time may require a Paying Agent to pay all money held by it to the Trustee
and account for any funds disbursed, and the Trustee may at any time during
the continuance of any payment default, upon written request to a Paying
Agent, require such Paying Agent to pay all money held by it to the Trustee
and to account for any funds disbursed.  Upon doing so, the Paying Agent
shall have no further liability for the money so paid over to the Trustee.
If the Company or any Subsidiary of the Company or any Affiliate of any of
them acts as Paying Agent, it will, on or before each due date of any
principal of, premium, if any, or interest on the Securities, segregate and
hold in a separate trust fund for the benefit of the Holders a sum of money
sufficient to pay such principal, premium, if any, or interest so becoming
due until such sum of money shall be paid to such Holders or otherwise
disposed of as provided in this Indenture, and will promptly notify the
Trustee of its action or failure to act.  The Company may pay on any due date
of the principal, premium, if any, or interest on the Securities such amount
that is due and payable by its check payable in lawful money of the United
States and mailed to each Holder's registered address as reflected in the
Security Register.

          2.06.   Transfer and Exchange.  The Securities are issuable only in
registered form.  The Series A Notes shall initially be issued as part of an
issuance of Units (the "Units"), each of which consists of a Series A Note
having a principal amount at maturity of $1,000 and Warrants to purchase 30
shares of Common Stock (the "Warrants").  Prior to the close of business upon
the earliest to occur of (i) January 30, 1996, (ii) the commencement of the
Exchange Offer, (iii) such earlier date as the Initial Purchaser may
determine and specify to the Trustee in writing, and (iv) in the event of a
Change of Control, the date the Company mails notice thereof to the Holders,
the Series A Notes may not be transferred or exchanged separately from, but
may be transferred or exchanged only together with, the Warrants.  A Holder
may transfer a Security by written application to the Registrar stating the
name of the proposed transferee and otherwise complying with the terms of
this Indenture.  No such transfer shall be effected until, and such
transferee shall succeed to the rights of a Holder only upon, final
acceptance and registration of the transfer by the Registrar in the Security
Register.  Prior to the registration of any transfer by a Holder as provided
herein, the Company, the Trustee, and any agent of the Company shall treat
the person in whose name the Security is registered as the owner thereof for
all purposes whether or not the Security shall be overdue, and neither the
Company, the Trustee, nor any such agent shall be affected by notice to the
contrary.  Furthermore, the Depository shall, by acceptance of a Global
Security, agree that transfers of beneficial interests in such Global
Security may be effected only through a book-entry system maintained by the
Depository (or its agent), and that ownership of a beneficial interest in the
Security shall be required to be reflected in a book entry.  When Securities
are presented to the Registrar or a co-Registrar with a request to register
the transfer or to exchange them for an equal principal amount of Securities
<PAGE>

of other authorized denominations (including on exchange of Series A Notes
for Series B Notes), the Registrar shall register the transfer or make the
exchange as requested if its requirements for such transactions are met;
provided that no exchanges of Series A Notes for Series B Notes shall occur
until a Registration Statement shall have been declared effective by the
Commission (with written notice thereof from the Company to the Trustee) and
that any Series A Notes that are exchanged for Series B Notes shall be
canceled by the Trustee.  To permit registrations of transfers and exchanges
in accordance with the terms, conditions and restrictions hereof, the Company
shall execute and the Trustee shall authenticate Securities at the
Registrar's request.  No service charge shall be made for any registration of
transfer or exchange or redemption of the Securities, but the Company may
require payment of a sum sufficient to cover any transfer tax or similar
governmental charge payable in connection therewith (other than any such
transfer taxes or other similar governmental charge payable upon exchanges
pursuant to Section 2.11, 3.06 or 9.05).

          The Registrar shall not be required (i) to issue, register the
transfer of or exchange any Security during a period beginning at the opening
of business 15 days before the day of the mailing of a notice of redemption
of Securities selected for redemption under Section 3.02 and ending at the
close of business on the day of such mailing, (ii) to register the transfer
of or exchange any Security so selected for redemption in whole or in part,
except the unredeemed portion of any Security being redeemed in part or
(iii) to register the transfer of or exchange any security between a record
date and the next succeeding interest payment date.

          2.07.   Book-Entry Provisions for the Global Securities.  (a)  The
Global Securities initially shall (i) be registered in the name of the
Depository or the nominee of such Depository, (ii) be delivered to the
Trustee as custodian for the Depository and (iii) bear legends as set forth
in Section 2.02.

          Members of, or participants in, the Depository ("Agent Members")
shall have no rights under this Indenture with respect to any Global Security
held on their behalf by the Depository, or the Trustee as its custodian, or
under the Global Security, and the Depository may be treated by the Company,
the Trustee and any agent of the Company or the Trustee as the absolute owner
of such Global Security for all purposes whatsoever.  Notwithstanding the
foregoing, nothing herein shall prevent the Company, the Trustee or any agent
of the Company or the Trustee, from giving effect to any written
certification, proxy or other authorization furnished by the Depository or
impair, as between the Depository and its Agent Members, the operation of
customary practices governing the exercise of the rights of a holder of any
Security.

          (b)  Transfers of any Global Security shall be limited to transfers
of such Global Security in whole, but not in part, to the Depository, its
successors or their respective nominees.  Beneficial interests in any Global
Security may be transferred in accordance with the applicable rules and
procedures of the Depository and, if applicable, Euroclear and Cedel and the
provisions of Section 2.08.  If, for any reason, a beneficial owner requires
physical delivery of a Physical Security, such beneficial owner shall
transfer its interest in the Global Security in exchange for Physical
Securities in accordance with the applicable rules and procedures of the
Depository and, if applicable, Euroclear and Cedel and the provisions of
Section 2.08.  In addition, Physical Securities shall be transferred to all
beneficial owners in exchange for their beneficial interests in any Security
if (i) the Depository notifies the Company that it is unwilling or unable to
continue as Depository for such Global Security and a successor Depository is
not appointed by the Company within 90 days of such notice or (ii) an Event
of Default has occurred and is continuing and the Registrar has received a
request from the Depository.

          (c)  Any beneficial interest in one of the Global Securities that
is transferred to a person who takes delivery in the form of an interest in
the other Global Security will, upon transfer, cease to be an interest in
such Global Security and become an interest in the other Global Security and,
accordingly, will thereafter be subject to all transfer restrictions, if any,
and other procedures applicable to beneficial interests in such other Global
Security for as long as it remains such an interest.
<PAGE>

          (d)  In connection with any transfer of a beneficial interest in
the U.S. Global Security to a transferee receiving Physical Securities
pursuant to paragraph (b) of this Section, the Registrar shall reflect on its
books and records the date and a decrease in the principal amount of the U.S.
Global Security in an amount equal to the principal amount of the beneficial
interest in the U.S. Global Security to be transferred, and the Company shall
execute, and the Trustee shall authenticate and deliver, one or more Physical
Securities of like tenor and amount.

          (e)  In connection with the transfer of an entire Global Security
to beneficial owners pursuant to paragraph (b) of this Section, such Global
Security shall be deemed to be surrendered to the Trustee for cancellation,
and the Company shall execute, and the Trustee shall authenticate and
deliver, to each beneficial owner identified by the Depository in exchange
for its beneficial interest in such Global Security an equal aggregate
principal amount of Physical Securities of authorized denominations.

          (f)  Any Physical Security delivered in exchange for an interest in
the U.S. Global Security or the Temporary Offshore Global Security pursuant
to paragraphs (b), (d) or (e) of this Section shall, except as otherwise
provided by paragraph (f) of Section 2.08, bear the legend regarding transfer
restrictions applicable to the Physical Security set forth in Sections
2.02(a) and 2.02(c).

          (g)  The registered holder of a Global Security may grant proxies
and otherwise authorize any person, including Agent Members and persons that
may hold interests through Agent Members, to take any action which a Holder
is entitled to take under this Indenture or the Securities.

          2.08.   Special Transfer Provisions.  Unless and until the Series A
Notes are exchanged for Series B Notes or otherwise transferred pursuant to
an effective Registration Statement in accordance with the Registration
Rights Agreement, the following provisions shall apply:

               (a)  Transfers to Non-QIB Institutional Accredited Investors.

     Note, whether or not such Series A Note bears the Private Placement
     Legend, if the proposed transferee has delivered to the Registrar (x) a
     certificate reasonably acceptable to the Trustee that the requested
     transfer is at least three years after the later of the Issue Date and
     the last date on which such Series A Note was held by an Affiliate of
     the Company or (y)(A) a certificate substantially in the form of Exhibit
     E hereto and (B) if the Accreted Value of the Series A Notes being

     Opinion of Counsel acceptable to the Company, the Registrar and the
     Trustee that such transfer is in compliance with the Securities Act.

           (ii)   If the proposed transferor is an Agent Member holding a
     beneficial interest in the U.S. Global Security or the Offshore Global
     Securities, upon receipt by the Registrar of (x) the documents, if any,
     required by paragraph (i) and (y) instructions given in accordance with
     the Depository's and the Registrar's procedures, the Registrar shall
     reflect on its books and records the date and a decrease in the
     principal amount of such Global Security in an amount equal to the
     principal amount of the beneficial interest in such Global Security to
     be transferred, and the Company shall execute, and the Trustee shall
     authenticate and deliver, one or more Physical Certificates of like
     tenor and amount.

               (b)  Transfers to QIBs.  The following provisions shall apply
     with respect to the registration of any proposed transfer of a Series A
     Note to a QIB:

            (i)   If the Series A Note to be transferred consists of Physical
     Securities or an interest in the Temporary Offshore Global Security, the
     Registrar shall register the transfer if such transfer is being made by
     a proposed transferor who has checked the box provided for on the form
     of Series A Note stating, or has otherwise advised the Company and the
     Registrar in writing, that the sale has been made in compliance with the
<PAGE>

     provisions of Rule 144A to a transferee who has signed the certification
     provided for on the form of Series A Note stating, or has otherwise
     advised the Company and the Registrar in writing, that it is purchasing
     the Series A Note for its own account or an account with respect to
     which it exercises sole investment discretion and that it and any such
     account is a QIB within the meaning of Rule 144A, and is aware that the
     sale to it is being made in reliance on Rule 144A and acknowledges that
     it has received such information regarding the Company as it has
     requested pursuant to Rule 144A or has determined not to request such
     information and that it is aware that the transferor is relying upon its
     foregoing representations in order to claim the exemption from
     registration provided by Rule 144A.

           (ii)   If the proposed transferee is an Agent Member and the
     Series A Note to be transferred consists of Physical Securities or an
     interest in the Temporary Offshore Global Security, upon receipt by the
     Registrar of the documents referred to in clause (i) and instructions
     given in accordance with the Depository's and the Registrar's
     procedures, the Registrar shall reflect on its books and records the
     date and an increase in the principal amount of the U.S. Global Security
     in an amount equal to the principal amount of the Physical Securities or
     the interest in the Temporary Offshore Global Security, as the case may
     be, to be transferred, and the Trustee shall cancel the Physical
     Securities or decrease the amount of the Temporary Offshore Global
     Security so transferred.

               (c)  Transfers of Interests in the Temporary Offshore Global
     Security.  The following provisions shall apply with respect to
     registration of any proposed transfer of interests in the Temporary
     Offshore Global Security:

            (i)   The Registrar shall register the transfer of any Series A
     Note (x) if the proposed transferee is a Non-U.S. Person and the
     proposed transferor has delivered to the Registrar a certificate
     substantially in the form of Exhibit F hereto or (y) if the proposed
     transferee is a QIB and the proposed transferor has checked the box
     provided for on the form of Series A Note stating, or has otherwise
     advised the Company and the Registrar in writing, that the sale has been
     made in compliance with the provisions of Rule 144A to a transferee who
     has signed the certification provided for on the form of Series A Note
     stating, or has otherwise advised the Company and the Registrar in
     writing, that it is purchasing the Series A Note for its own account or

     144A, and is aware that the sale to it is being made in reliance on Rule

     is relying upon its foregoing representations in order to claim the
     exemption from registration provided by Rule 144A.

           (ii)   If the proposed transferee is an Agent Member, upon receipt
     by the Registrar of the documents referred to in clause (i)(y) above and
     instructions given in accordance with the Depository's and the
     Registrar's procedures, the Registrar shall reflect on its books and
     records the date and an increase in the principal amount of the U.S.
     Global Security in an amount equal to the principal amount of the
     Temporary Offshore Global Security to be transferred, and the Trustee
     shall decrease the amount of the Temporary Offshore Global Security.

               (d)  Transfers of Interests in the Permanent Offshore Global
     Security to U.S. Persons.  The following provision shall apply with
     respect to any transfer of interests in the Permanent Offshore Global
     Security to U.S. Persons:  The Registrar shall register the transfer of
     any Security without requiring any additional certification.

               (e)  Transfers to Non-U.S. Persons at any Time. The following
     provisions shall apply with respect to any transfer of a Series A Note
     to a Non-U.S. Person:
<PAGE>

            (i)   Prior to August 15, 1995, the Registrar shall register any
     proposed transfer of a Series A Note to a Non-U.S. Person upon receipt
     of a certificate substantially in the form of Exhibit F hereto from the
     proposed transferor.

           (ii)   On and after August 15, 1995, the Registrar shall register
     any proposed transfer to any Non-U.S. Person if the Series A Note to be
     transferred is an interest in the U.S. Global Security, upon receipt of
     a certificate substantially in the form of Exhibit F from the proposed
     transferor.

          (iii)   (a) If the proposed transferor is an Agent Member holding a
     beneficial interest in the U.S. Global Security, upon receipt by the
     Registrar of (x) the documents, if any, required by paragraph (ii) and
     (y) instructions in accordance with the Depository's and the Registrar's
     procedures, the Registrar shall reflect on its books and records the
     date and a decrease in the principal amount of the U.S. Global Security
     in an amount equal to the principal amount of the beneficial interest in
     the U.S. Global Security to be transferred, and (b) if the proposed
     transferee is an Agent Member, upon receipt by the Registrar of
     instructions given in accordance with the Depository's and the
     Registrar's procedures, the Registrar shall reflect on its books and
     records the date and an increase in the principal amount of the Offshore
     Global Security in an amount equal to the principal amount of the U.S.
     Global Security to be transferred, and the Trustee shall decrease the
     amount of the U.S. Global Security.

               (f)  Private Placement Legend.  Upon the transfer, exchange or
     replacement of Series A Notes not bearing the Private Placement Legend,
     the Registrar shall deliver Series A Notes that do not bear the Private
     Placement Legend.  Upon the transfer, exchange or replacement of Series
     A Notes bearing the Private Placement Legend, the Registrar shall
     deliver only Series A Notes that bear the Private Placement Legend
     unless either (i) the circumstances contemplated by the fourth paragraph
     of Section 2.01 or paragraph (a)(i)(x) or (e)(ii) of this Section 2.08
     exist or (ii) there is delivered to the Registrar an Opinion of Counsel
     reasonably satisfactory to the Company, the Registrar and the Trustee to
     the effect that neither such legend nor the related restrictions on
     transfer are required in order to maintain compliance with the
     provisions of the Securities Act.

               (g)  General.  The provisions of Sections 2.01, 2.02, 2.07 and
     2.08 hereof shall be qualified in their entirety by any applicable
     securities laws of the United States and any other applicable
     jurisdiction and by the procedures of any applicable clearing agency, in
     each case as in effect from time to time, and all such laws and clearing
     procedures shall be deemed to be incorporated herein by reference.  By
     its acceptance of any Series A Note bearing the Private Placement
     Legend, each Holder of such a Series A Note shall be deemed to
     acknowledge the restrictions on transfer of such Series A Note set forth
     in this Indenture and in the Private Placement Legend and agrees that it
     will transfer such Series A Note only as provided in this Indenture.
     The Registrar shall not register a transfer of any Series A Note unless
     such transfer complies with the restrictions on transfer of such Series
     A Note set forth in this Indenture.  In connection with any transfer of
     Series A Notes, each Holder agrees by its acceptance of the Series A
     Notes to furnish the Registrar or the Company such certifications, legal
     opinions or other information as either of them may reasonably require
     to confirm that such transfer is being made pursuant to an exemption
     from, or a transaction not subject to, the registration requirements of
     the Securities Act; provided that the Registrar shall not be required to
     determine (but may rely on a determination made by the Company with
     respect to) the sufficiency of any such certifications, legal opinions
     or other information.

          The Registrar shall retain copies of all letters, notices and other
written communications received pursuant to Section 2.07 or this Section
2.08.  The Company shall have the right to inspect and make copies of all
such letters, notices or other written communications at any reasonable time
upon the giving of reasonable written notice to the Registrar.
<PAGE>

          2.09.   Replacement Securities.  If a mutilated Security is
surrendered to the Trustee or if the Holder claims that the Security has been
lost, destroyed or wrongfully taken, the Company shall issue and the Trustee
shall authenticate a replacement Security of like tenor and principal amount
and bearing a number not contemporaneously outstanding; provided that the
requirements of the second paragraph of Section 2.10 are met.  If required by
the Trustee or the Company, an indemnity bond must be furnished that is
sufficient in the judgment of both the Trustee and the Company to protect the
Company, the Trustee or any Agent from any loss that any of them may suffer
if a Security is replaced.  The Company may charge such Holder for its
expenses and the expenses of the Trustee in replacing a Security.  In case
any such mutilated, lost, destroyed or wrongfully taken Security has become
or is about to become due and payable, the Company in its discretion may pay
such Security instead of issuing a new Security in replacement thereof.

          Every replacement Security is an additional obligation of the
Company and shall be entitled to the benefits of this Indenture.

          2.10.   Outstanding Securities.  Securities outstanding at any time
are all Securities that have been authenticated by the Trustee, except for
those canceled by it, those delivered to it for cancellation and those
described in this Section 2.10 as not outstanding.

          If a Security is replaced pursuant to Section 2.09, it ceases to be
outstanding unless and until the Trustee and the Company receive proof
satisfactory to them that the replaced Security is held by a bona fide
purchaser.

          If the Paying Agent (other than the Company or an Affiliate of the
Company) holds on the maturity date money sufficient to pay Securities
payable on that date, then on and after that date, such Securities cease to
be outstanding and interest on them shall cease to accrue.

          A Security does not cease to be outstanding because the Company or
one of its Affiliates holds such Security, provided, however, that, in
determining whether the Holders of the requisite principal amount of the
outstanding Securities have given any request, demand, authorization,
direction, notice, consent or waiver hereunder, Securities owned by the
Company or any other obligor upon the Securities or any Affiliate of the
Company or of such other obligor shall be disregarded and deemed not to be
outstanding, except that, in determining whether the Trustee shall be
protected in relying upon any such request, demand, authorization, direction,
notice, consent or waiver, only Securities which the Trustee knows to be so
owned shall be so disregarded.  Securities so owned which have been pledged
in good faith may be regarded as outstanding if the pledgee establishes to
the satisfaction of the Trustee the pledgee's right so to act with respect to
such Securities and that the pledgee is not the Company or any other obligor
upon the Securities or any Affiliate of the Company or of such other obligor.

          2.11.   Temporary Securities.  Until definitive Securities are
ready for delivery, the Company may prepare and the Trustee shall
authenticate temporary Securities.  Temporary Securities shall be
substantially in the form of definitive Securities but may have insertions,
substitutions, omissions and other variations determined to be appropriate by
the Officers executing the temporary Securities, as evidenced by their
execution of such temporary Securities.  If temporary Securities are issued,
the Company will cause definitive Securities to be prepared without
unreasonable delay.  After the preparation of definitive Securities, the
temporary Securities shall be exchangeable for definitive Securities upon
surrender of the temporary Securities at the office or agency of the Company
designated for such purpose pursuant to Section 4.02, without charge to the
Holder.  Upon surrender for cancellation of any one or more temporary
Securities the Company shall execute and the Trustee shall authenticate and
deliver in exchange therefor a like principal amount of definitive Securities
of authorized denominations.  Until so exchanged, the temporary Securities
shall be entitled to the same benefits under this Indenture as definitive
Securities.
<PAGE>

          2.12.   Cancellation.  The Company at any time may deliver to the
Trustee for cancellation any Securities previously authenticated and
delivered hereunder which the Company may have acquired in any manner
whatsoever, and may deliver to the Trustee for cancellation any Securities
previously authenticated hereunder which the Company has not issued and sold.
The Registrar and the Paying Agent shall forward to the Trustee any
Securities surrendered to them for transfer, exchange or payment.  The
Trustee shall cancel all Securities surrendered for transfer, exchange,
payment or cancellation and shall dispose of them in accordance with its
normal procedure or the written instructions of the Company.

          2.13.   CUSIP Numbers.  The Company in issuing the Securities may
use "CUSIP" and CINS numbers (if then generally in use), and the Trustee
shall use CUSIP numbers or CINS numbers, as the case may be, in notices of
redemption or exchange as a convenience to Holders; provided that any such
notice shall state that no representation is made as to the correctness of
such numbers either as printed on the Securities or as contained in any
notice of redemption or exchange and that reliance may be placed only on the
other identification numbers printed on the Securities.

          2.14.   Defaulted Interest.  If the Company defaults in a payment
of interest on the Securities, it shall pay, or shall deposit with the Paying
Agent, money in immediately available funds sufficient to pay the defaulted
interest, plus (to the extent lawful) any interest payable on the defaulted
interest, to the Persons who are Holders on a subsequent special record date.
A special record date, as used in this Section 2.14 with respect to the
payment of any defaulted interest, shall mean the 15th day next preceding the
date fixed by the Company for the payment of defaulted interest, whether or
not such day is a Business Day.  At least 15 days before the subsequent
special record date, the Company shall mail to each Holder and to the Trustee
a notice that states the subsequent special record date, the payment date and
the amount of defaulted interest to be paid.

          2.15.   Securityholder Lists.  The Trustee shall preserve in as
current a form as is reasonably practicable the most recent list available to
it of the names and addresses of Securityholders and shall otherwise comply
with TIA * 312(a).  If the Trustee is not the Registrar, the Company shall
furnish to the Trustee at least seven Business Days before each interest
payment date and at such other times as the Trustee may request in writing a
list in such form and as of such date as the Trustee may reasonably require
of the names and addresses of Securityholders, and the Company shall
otherwise comply with TIA * 312(a).

          2.16.   Other Transfers.  Notwithstanding anything to the contrary
in this Article Two, the Registrar may register the transfer of any Security
to any "accredited investor" as defined in Rule 501(a)(5) under the
Securities Act upon the delivery to the Registrar of documentation (including
certificates of the transferee and an Opinion of Counsel) in form and
substance satisfactory to the Company, the Registrar and the Trustee, to the
effect that such transfer is in compliance with the securities laws of the
United States and the various states thereof.

          2.17.   Record Date.  The record date for purposes of determining
the identity of Securityholders entitled to vote or consent to any action
authorized or permitted under this Indenture shall be determined as provided
for in TIA * 316(c).

                                 ARTICLE THREE

                            REDEMPTION OF SECURITIES

          3.01.   Notices to the Trustee.

          If the Company elects to redeem Securities pursuant to Paragraph
3(a) or 3(b) of the Securities, it shall notify the Trustee of the Redemption
Date and principal amount of Securities to be redeemed.

          The Company shall notify the Trustee by an Officers' Certificate,
stating that such redemption will comply with the provisions hereof and of
the Securities, of any redemption at least 45 but not more than 60 days
before the Redemption Date or such shorter period as may be acceptable to the
Trustee.

          3.02.   Selection of Securities To Be Redeemed.

          If less than all the Securities are to be redeemed, the particular
Securities or portions thereof to be redeemed shall be selected from the
outstanding Securities not previously called for redemption either (x) pro
rata, by lot or by such other method as the Trustee considers to be fair and
appropriate or (y) in such manner as complies with the requirements of the
principal national securities exchange, if any, on which the Securities being
redeemed are listed.  The amounts to be redeemed shall be equal to $1,000
principal amount at maturity or any integral multiple thereof.

          The Trustee shall promptly notify the Company and the Registrar in
writing of the Securities selected for redemption and, in the case of any
Securities selected for partial redemption, the principal amount thereof to
be redeemed.

          For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to redemption of Securities shall relate,
in the case of any Security redeemed or to be redeemed only in part, to the
portion of the principal amount of such Security which has been or is to be
redeemed.

          3.03.   Notice of Redemption.

          Notice of redemption shall be given by first-class mail, postage
prepaid, mailed not less than 30 nor more than 60 days prior to the
Redemption Date, to each Holder of Securities to be redeemed, at the address
of such Holder appearing in the Security Register maintained by the
Registrar.

          All notices of redemption shall identify the Securities to be
redeemed and shall state:
          (a)  the Redemption Date;
          (b)  the Redemption Price and the amount of accrued interest, if
     any, to be paid;
          (c)  that, unless the Company defaults in making the redemption
     payment, interest on Securities called for redemption ceases to accrue
     on and after the Redemption Date, and the only remaining right of the
     Holders of such Securities is to receive payment of the Redemption Price
     upon surrender to the Paying Agent of the Securities redeemed;
          (d)  if any Security is to be redeemed in part, the portion of the
     principal amount (equal to $1,000 or any integral multiple thereof) of
     such Security to be redeemed and that on and after the Redemption Date,
     upon surrender for cancellation of such original Security to the Paying
     Agent, a new Security or Securities in the aggregate principal amount
     equal to the unredeemed portion thereof will be issued without charge to
     the Holder;
          (e)  that Securities called for redemption must be surrendered to
     the Paying Agent to collect the Redemption Price and the name and
     address of the Paying Agent;
          (f)  the CUSIP number, if any, relating to such Securities, but no
     representation is made as to the correctness or accuracy of any such
     CUSIP number; and
          (g)  the paragraph of the Securities pursuant to which the
     Securities are being redeemed.
<PAGE>

Notice of redemption of Securities to be redeemed at the election of the
Company shall be given by the Company or, at the Company's written request,
by the Trustee in the name and at the expense of the Company; provided,
however, that the Company shall furnish the Trustee with the contents of such
notice.

          3.04.   Effect of Notice of Redemption.

          Once notice of redemption is mailed, Securities called for
redemption become due and payable on the Redemption Date and at the
Redemption Price.  Upon surrender to the Paying Agent, such Securities called
for redemption shall be paid at the Redemption Price plus accrued interest to
the Redemption Date, but interest installments whose maturity is on or prior
to such Redemption Date will be payable on the relevant Interest Payment
Dates to the Holders of record at the close of business on the relevant
record dates referred to in the Securities.

          3.05.   Deposit of Redemption Price.

          On or prior to any Redemption Date, the Company shall deposit with
the Paying Agent an amount of money in same day funds sufficient to pay the
Redemption Price of, and accrued interest on, all the Securities or portions
thereof which are to be redeemed on that date, other than Securities or
portions thereof called for redemption on that date which have been delivered
by the Company to the Trustee for cancellation.

          If the Company complies with the preceding paragraph, then, unless
the Company defaults in the payment of such Redemption Price, interest on the
Securities to be redeemed will cease to accrue on and after the applicable
Redemption Date, whether or not such Securities are presented for payment.
If any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal, premium, if any, and, to the extent
lawful, accrued interest thereon shall, until paid, bear interest from the
Redemption Date at the rate provided in the Securities.

          3.06.   Securities Redeemed or Purchased in Part.

          Upon surrender to the Paying Agent of a Security which is to be
redeemed in part, the Company shall execute and the Trustee shall
authenticate and deliver to the Holder of such Security without service
charge, a new Security or Securities, of any authorized denomination as
requested by such Holder in aggregate principal amount equal to, and in
exchange for, the unredeemed portion of the principal of the Security so
surrendered that is not redeemed.

                                  ARTICLE FOUR

                                   COVENANTS

          4.01.   Payment of Securities.

          The Company will pay, or cause to be paid, the principal of and
interest on the Securities by 10:30 a.m. New York City time on the dates and
in the manner provided in the Securities and this Indenture.  An installment
of principal or interest shall be considered paid on the date due if the
Trustee or Paying Agent (other than the Company, a Subsidiary of the Company
or any Affiliate thereof) holds on that date money designated and set aside
for and sufficient to pay the installment in a timely manner and is not
prohibited from paying such money to the Holders of the Securities pursuant
to the terms of this Indenture.

          The Company will pay interest on overdue principal at the rate and
in the manner provided in the Securities; it shall pay interest on overdue
installments of interest at the same rate and in the same manner, to the
extent lawful.

          4.02.   Maintenance of Office or Agency.

          The Company will maintain in the Borough of Manhattan, The City of
New York, an office or agency where Securities may be surrendered for
registration of transfer or exchange or for presentation for payment and
where notices and demands to or upon the Company in respect of the Securities
and this Indenture may be served.  The Company will give prompt written
notice to the Trustee of the location, and any change in the location, of
such office or agency.  If at any time the Company shall fail to maintain any
such required office or agency or shall fail to furnish the Trustee with the
address thereof, such presentations, surrenders, notices and demands may be
made or served at the address of the Trustee as set forth in Section 11.02.
<PAGE>

          The Company may also from time to time designate one or more other
offices or agencies where the Securities may be presented or surrendered for
any or all such purposes and may from time to time rescind such designations;
provided, however, that no such designation or rescission shall in any manner
relieve the Company of its obligation to maintain an office or agency in the
Borough of Manhattan, The City of New York, for such purposes.  The Company
will give prompt written notice to the Trustee of any such designation or
rescission and of any change in the location of any such other office or
agency.
          The Company hereby initially designates the office of the Trustee,
IBJ Schroder Bank & Trust Company, located at One State Street in the Borough
of Manhattan, City of New York 10004, as such office of the Company in
accordance with this Section 4.02.

          4.03.   Corporate Existence.

          Subject to Article Five, the Company shall do or cause to be done
all things necessary to and will cause each of its Subsidiaries to, preserve
and keep in full force and effect the corporate or partnership existence and
rights (charter and statutory), licenses and/or franchises of the Company and
each of its Subsidiaries; provided, however, that the Company or any of its
Subsidiaries shall not be required to preserve any such rights, licenses or
franchises if the Board of Directors shall reasonably determine that (x) the
preservation thereof is no longer desirable in the conduct of the business of
the Company and its Subsidiaries taken as a whole and (y) the loss thereof is
not materially adverse to either the Company and its Subsidiaries taken as a
whole or to the ability of the Company to otherwise satisfy its obligations
hereunder.

          4.04.   Payment of Taxes and Other Claims.

          The Company will pay or discharge or cause to be paid or
discharged, before the same shall become delinquent, (a) all taxes,
assessments and governmental charges levied or imposed upon the Company or
any of its Subsidiaries or upon the income, profits or property of the
Company or any of its Subsidiaries, and (b) all lawful claims for labor,
materials and supplies which, if unpaid, might by law become a Lien upon the
property of the Company or any Subsidiary of the Company; provided, however,
that the Company shall not be required to pay or discharge or cause to be
paid or discharged any such tax, assessment, charge or claim, the amount,
applicability or validity of which is being contested in good faith by
appropriate proceedings and for which adequate provision has been made or
where the failure to effect such payment or discharge is not adverse in any
material respect to the Company and its Subsidiaries taken as a whole.

          4.05.   Maintenance of Properties; Insurance;
                  Books and Records; Compliance with Law.

to, cause all properties and assets to be maintained and kept in good
condition, repair and working order (reasonable wear and tear excepted) and
supplied with all necessary equipment, and shall cause to be made all
necessary repairs, renewals, replacements, additions, betterments and
improvements thereto, as shall be reasonably necessary for the proper conduct
of its business; provided, however, that nothing in this Section 4.05(a)
shall prevent the Company or any of its Subsidiaries from discontinuing the
operation and maintenance of any of its properties or assets if such
discontinuance is, in the judgment of the Board of Directors of the Company
or such Subsidiary, desirable in the conduct of its business and if such
discontinuance is not materially adverse to either the Company and its
Subsidiaries taken as a whole or the ability of the Company to otherwise
satisfy its obligations hereunder.
          (b)  The Company shall, and shall cause each of its Subsidiaries
to, maintain with financially sound and reputable insurers such insurance as
may be required by law (other than with respect to any environmental
impairment liability insurance not commercially available) and such other
insurance to such extent and against such hazards and liabilities, as is
customarily maintained by companies similarly situated (which may include
self-insurance in the same form as is customarily maintained by companies
similarly situated).
<PAGE>

          (c)  The Company shall, and shall cause each of its Subsidiaries
to, keep proper books of record and account, in which full and correct
entries shall be made of all material business and financial transactions of
the Company and each Subsidiary of the Company and reflect on its financial
statements adequate accruals and appropriations to reserves, all in
accordance with GAAP consistently applied to the Company and its Subsidiaries
taken as a whole.

          (d)  The Company shall and shall cause each of its Subsidiaries to
comply with all statutes, laws, ordinances, or government rules and
regulations to which it is subject, non-compliance with which would
materially adversely affect the business, earnings, properties, assets or
condition (financial or otherwise) of the Company and its Subsidiaries taken
as a whole.

          4.06.   Compliance Certificate.

          (a)  The Company will deliver to the Trustee within 60 days after
the end of each of the Company's first three fiscal quarters and within 90

year, but in no event later than 120 days after the end of such fiscal year,
an Officers' Certificate stating whether or not the signers know of any
Default or Event of Default under this Indenture by the Company.  If they do
know of such a Default or Event of Default, the certificate shall describe
any such Default or Event of Default and its status.  The first certificate
to be delivered pursuant to this Section 4.06(a) shall be for the first
fiscal quarter of the Company beginning after the Issue Date.  The Company
shall also deliver a certificate to the Trustee at least annually within 90
days after the end of each fiscal year, or such later date as the Company
files its annual report on Form 10-K with the SEC for such fiscal year, but
in no event later than 120 days after the end of such fiscal year, from its
principal executive, financial or accounting officer as to his or her
knowledge of the Company's compliance with all conditions and covenants under
this Indenture and the Pledge Agreements, such compliance to be determined
without regard to any period of grace or requirement of notice provided
herein.

          (b)  The Company shall deliver to the Trustee within 90 days after
the end of each fiscal year, or such later date as the Company files its
annual report on Form 10-K with the SEC for such fiscal year, but in no event
later than 120 days after the end of such fiscal year, a written statement by
the Company's independent certified public accountants stating (A) that their
audit examination has included a review of the terms of this Indenture and
the Securities as they relate to accounting matters, and (B) whether, in
connection with their audit examination, any Default or Event of Default
under this Indenture has come to their attention and, if such a Default or
Event of Default has come to their attention, specifying the nature and
period of existence thereof; provided, however, that, without any restriction
as to the scope of the audit examination, such independent certified public
accountants shall not be liable by reason of any failure to obtain knowledge
of any such Default or Event of Default that would not be disclosed in the
course of an audit examination conducted in accordance with GAAP.

          (c)  The Company will deliver to the Trustee as soon as possible,
and in any event within 10 days after the Company becomes aware or should
reasonably have become aware of the occurrence of any Default or Event of
Default, an Officers' Certificate specifying such Default or Event of Default
and what action the Company is taking or proposes to take with respect
thereto.

          4.07.   SEC Reports.

          The Company shall file with the SEC the annual reports, quarterly
reports and the information, documents and other reports required to be filed
with the SEC pursuant to Sections 13 and 15 of the Exchange Act, whether or
not the Company has a class of securities registered under the Exchange Act.
In accordance with the provisions of TIA Section 314(a), the Company shall file
with the Trustee and provide to each Holder, within 15 days after it files
them with the SEC (or if such filing is not permitted under the Exchange Act,
15 days after the Company would have been required to make such filing),

<PAGE>

reports (or copies of such portions of any of the foregoing as the SEC may by
rules and regulations prescribe) which the Company is required to file with
the SEC pursuant to Section 13 or 15 of the Exchange Act.  The Company also

addresses as set forth in the register of Securities maintained by the
Registrar.

          4.08.   Limitation on Indebtedness.

          The Company will not, and will not permit any of its Subsidiaries
to, directly or indirectly, create, incur, issue, assume, guarantee or in any
manner become directly or indirectly liable, contingently or otherwise, for
the payment of (in each case, to "incur") any Indebtedness (including,
without limitation, any Acquired Indebtedness); provided, however, that the
Company or any of its Subsidiaries (other than Subsidiaries whose Capital
Stock is then pledged under the Pledge Agreements or the direct or indirect
subsidiaries of such Subsidiaries) will be permitted to incur Indebtedness
(including, without limitation, Acquired Indebtedness) if (a) at the time of
such incurrence, no Default or Event of Default shall have occurred and be
continuing and (b) at the time of such incurrence and after giving pro forma
effect thereto, the Consolidated Indebtedness to Annualized Operating Cash
Flow Ratio would not exceed 7.0 to l.0 in the case of any such incurrence of
Indebtedness on or before January 1, 1999, or 4.5 to 1.0 in the case of any
such incurrence of Indebtedness thereafter.

          Notwithstanding the foregoing, the Company and its Subsidiaries

     (ii) Interest Rate Protection Obligations of any Subsidiary of the
     Company covering Indebtedness of such Subsidiary; provided, however,
     that, in the case of either clause (i) or (ii), (A) any Indebtedness to
     which any such Interest Rate Protection Obligation relates bears
     interest at a fluctuating interest rate and (B) the notional principal
     amount of any such Interest Rate Protection Obligation does not exceed
     the principal amount of the Indebtedness to which such Interest Rate
     Protection Obligation relates;

          (d)  Indebtedness of a Subsidiary of the Company owed to and held
     by the Company or another Subsidiary, except that (i) any transfer of

     transfer or other disposition by the Company or any Subsidiary of the
     Company of Capital Stock of a Subsidiary of the Company which is owed

     such Subsidiary ceases to be a Subsidiary of the Company shall, in each
     case, be an incurrence of Indebtedness by the second such Subsidiary,
     subject to the other provisions of this Section 4.08;

          (e)  Indebtedness of the Company owed to and held by a Subsidiary

     Indebtedness by a Subsidiary of the Company (other than to another
     Subsidiary of the Company) and (ii) the sale, transfer or other
     disposition by the Company or any Subsidiary of the Company of Capital
     Stock of a Subsidiary which holds Indebtedness of the Company such that
     it ceases to be a Subsidiary shall, in each case, be an incurrence of
     Indebtedness by the Company, subject to the other provisions of this
     Section 4.08;
<PAGE>

          (f)  Indebtedness under Currency Agreements; provided that in the
     case of Currency Agreements which relate to Indebtedness, such Currency
     Agreements do not increase the Indebtedness of the Company and its
     Subsidiaries outstanding other than as a result of fluctuations in
     foreign currency exchange rates or by reason of fees, indemnities and
     compensation payable thereunder;

          (g)  Indebtedness arising from the honoring by a bank or other
     financial institution of a check, draft or similar instrument
     inadvertently (except in the case of daylight overdrafts) drawn against

     incurrence;

          (l)  Indebtedness issued to finance the acquisition of

     $20,000,000; and

          (n)  (i) Indebtedness of the Company the proceeds of which are used
     solely to refinance (whether by amendment, renewal, substitution,
     replacement, extension or refunding) Indebtedness (plus reasonable fees
     and expenses directly associated with such financing) of the Company or
     any of its Subsidiaries and (ii) Indebtedness of any Subsidiary of the

     such financing) of such Subsidiary, in each case other than Indebtedness
     refinanced, redeemed or retired under clause (j), (k) or (m) of this
     Section 4.08; provided, however, that (A) the principal amount of
     Indebtedness incurred pursuant to this clause (n) (or, if such
     Indebtedness provides for an amount less than the principal amount
     thereof to be due and payable upon a declaration of acceleration of the
     maturity thereof, the original issue price of such Indebtedness) shall
     not exceed the sum of the principal amount of Indebtedness so
     refinanced, plus the amount of any premium required to be paid in
     connection with such refinancing pursuant to the terms of such
     Indebtedness or the amount of any premium reasonably determined by the
     Board of Directors as necessary to accomplish such refinancing by means
     of a tender offer or privately negotiated purchase, plus the amount of
     expenses in connection therewith and (B) in the case of Indebtedness
     incurred by the Company pursuant to this clause (n) to refinance
     Indebtedness subordinated in right of payment to the Securities, such
     Indebtedness (I) has an Average Life to Stated Maturity equal to or
     greater than the remaining Average Life to Stated Maturity of the
     Indebtedness being financed and (II) is subordinated to the Securities
     in the same manner and to the same extent that the Indebtedness being
     refinanced is subordinated to the Securities.

          For purposes of determining compliance with this Section 4.08, in
     the event that an item of Indebtedness meets the criteria of more than
     one of the types of Indebtedness described in the above clauses, the
     Company in its sole discretion, shall classify such item of Indebtedness
     and only shall be required to include the amount and type of such
     Indebtedness in one of such clauses.

          4.09.   Limitation on Restricted Payments.

          The Company will not, and will not permit any of its Subsidiaries
to, directly or indirectly:

          (a)  declare or pay any dividend or make any other distribution or
     payment on or in respect of Capital Stock of the Company or any of its
     Subsidiaries or any payment made to the direct or indirect holders (in
     their capacities as such) of Capital Stock of the Company or any of its
     Subsidiaries (other than (i) dividends or distributions payable solely
     in Capital Stock of the Company (other than Redeemable Capital Stock) or
     in options, warrants or other rights to purchase Capital Stock of the
     Company (other than Redeemable Capital Stock), (ii) the declaration or
     payment of dividends or other distributions to the extent declared or
     paid to the Company or any Wholly-Owned Subsidiary of the Company and
     (iii) the declaration or payment of dividends or other distributions by
     any Subsidiary of the Company to all holders of Common Stock of such
     Subsidiary on a pro rata basis);

          (b)  purchase, redeem, defease or otherwise acquire or retire for
     value any Capital Stock of the Company or any of its Subsidiaries (other
     than any such Capital Stock owned by a Wholly-Owned Subsidiary of the
     Company);

          (c)  make any principal payment on, or purchase, defease,
     repurchase, redeem or otherwise acquire or retire for value, prior to
     any scheduled maturity, scheduled repayment, scheduled sinking fund
     payment or other Stated Maturity, any Indebtedness that is subordinated
     in right of payment to the Securities (other than any such Indebtedness
     owned by the Company or a Wholly-Owned Subsidiary of the Company); or

          (d)  make any Investment (other than any Permitted Investment) in
     any person (such payments or Investments described in the preceding
     clauses (a), (b), (c) and this clause (d) are collectively referred to
     as "Restricted Payments");

provided, however, that the Company or any Subsidiary thereof may make a
Restricted Payment if, at the time of and after giving effect to the proposed
Restricted Payment (the amount of any such Restricted Payment, if other than
cash, shall be the Fair Market Value on the date of such Restricted Payment
of the asset(s) proposed to be transferred by the Company or such Subsidiary,
as the case may be, pursuant to such Restricted Payment), (i) no Default or
Event of Default shall have occurred and be continuing, (ii) after giving
effect to such Restricted Payment, the Company would be able to incur $1.00
of additional Indebtedness pursuant to clause (b) of the first paragraph of
Section 4.08 (assuming a market rate of interest with respect to such
additional Indebtedness) and (iii) the aggregate amount of all Restricted
Payments declared or made from and after the Issue Date would not exceed the
sum of (A) 50% of the aggregate Consolidated Net Income of the Company
accrued on a cumulative basis during the period beginning on the first day of
the fiscal quarter of the Company during which the Issue Date occurs and
ending on the last day of the fiscal quarter of the Company immediately
preceding the date of such proposed Restricted Payment, which period shall be
treated as a single accounting period (or, if such aggregate cumulative
Consolidated Net Income of the Company for such period shall be a deficit,
minus 100% of such deficit) plus (B) the aggregate net proceeds, including
the Fair Market Value of property other than cash, received by the Company
either (I) as capital contributions to the Company after the Issue Date from
any person (other than a Subsidiary of the Company) or (II) from the issuance
or sale of Capital Stock (excluding Redeemable Capital Stock and Capital
Stock issued pursuant to clause (j) of the definition of "Permitted
Investments," but including Capital Stock issued upon the conversion of
convertible Indebtedness (including Indebtedness that is Redeemable Capital
Stock) or from the exercise of options, warrants or rights to purchase
Capital Stock (other than Redeemable Capital Stock and Capital Stock issued
pursuant to clause (j) of the definition of "Permitted Investments")) of the
Company to any person (other than to a Subsidiary of the Company) after the
Issue Date plus (C) in the case of the disposition or repayment of any
Investment constituting a Restricted Payment made after the Issue Date
(excluding any Investment described in clause (i) of the following
paragraph), an amount equal to the lesser of the return of capital with
<PAGE>

respect to such Investment and the cost of such Investment, in either case,
less the cost of the disposition of such Investment.  For purposes of the
preceding clause (iii)(B), (x) the value of the aggregate net cash proceeds
received by the Company upon the issuance of Capital Stock upon the
conversion of convertible Indebtedness (including Indebtedness that is
Redeemable Capital Stock) or upon the exercise of options, warrants or rights
will be the net cash proceeds received upon the issuance of such
Indebtedness, options, warrants or rights plus the incremental cash amount
received by the Company upon the conversion or exercise thereof and (y) the
Fair Market Value of property other than cash shall be determined by the
Board of Directors, whose good faith determination shall be conclusive and
evidenced by (i) a resolution filed with the Trustee and (ii) in the case of
Fair Market Value in excess of $20 million, a written opinion as to such Fair
Market Value issued by an Independent Financial Advisor.

          None of the foregoing provisions will prohibit (a) the payment of
any dividend within 60 days after the date of its declaration, if at the date
of declaration such payment would be permitted by the foregoing paragraph;
(b) so long as no Default or Event of Default shall have occurred and be
continuing, the redemption, repurchase or other acquisition or retirement of
any shares of any class of Capital Stock of the Company in exchange for, or
out of the net cash proceeds of, a substantially concurrent (i) capital
contribution to the Company from any person (other than a Subsidiary of the
Company) or (ii) issue and sale of other shares of Capital Stock (other than
Redeemable Capital Stock) of the Company to any person (other than a
Subsidiary of the Company), provided, however, that the amount of any such
net cash proceeds that are utilized for any such redemption, repurchase or
other acquisition or retirement shall be excluded from clause (iii)(B) of the
preceding paragraph; (c) so long as no Default or Event of Default shall have
occurred and be continuing, any redemption, repurchase or other acquisition
or retirement of Indebtedness that is subordinated in right of payment to the
Securities by exchange for, or out of the net cash proceeds of, a
substantially concurrent (i) capital contribution to the Company from any
person (other than a Subsidiary of the Company) or (ii) issue and sale of
(A) Capital Stock (other than Redeemable Capital Stock) of the Company to any
person (other than to a Subsidiary of the Company), provided, however, that
the amount of any such net cash proceeds that are utilized for any such
redemption, repurchase or other acquisition or retirement shall be excluded

and the Paying Agent.  The Change of Control Offer shall remain open from the

City time, on the Change of Control Purchase Date.  The notice, which shall
govern the terms of the Change of Control Offer, shall include such

          (a)  that the Change of Control Offer is being made pursuant to
     this Section 4.11 and that all Securities validly tendered into the
     Change of Control Offer and not withdrawn will be accepted for payment;
<PAGE>

          (b)  the purchase price (including the amount of accrued interest,
     if any) for each Security, the Change of Control Purchase Date and the
     date on which the Change of Control Offer expires;

          (c)  that any Security not tendered for payment will continue to
     accrue interest in accordance with the terms thereof;

          (d)  that, unless the Company shall default in the payment of the
     purchase price, any Security accepted for payment pursuant to the Change

     Control Purchase Date;

          (e)  that Holders electing to have Securities purchased pursuant to
     a Change of Control Offer will be required to surrender their Securities

     on the third Business Day immediately preceding the Change of Control
     Purchase Date, a telex, facsimile transmission or letter setting forth
     the name of the Holder, the principal amount of Securities the Holder
     delivered for purchase, the Security certificate number (if any) and a
     statement that such Holder is withdrawing its election to have such
     Securities purchased;

          (g)  that Holders whose Securities are purchased only in part will
     be issued Securities equal in principal amount to the unpurchased
     portion of the Securities surrendered;

          (h)  the instructions that Holders must follow in order to tender
     their Securities; and

          (i)  information concerning the business of the Company, the most
     recent annual and quarterly reports of the Company filed with the SEC

     to file any such reports with the SEC, the comparable reports prepared
     pursuant to Section 4.07), a description of material developments in the
     Company's business, information with respect to pro forma historical
     financial information after giving effect to such Change of Control and

     regarding such Change of Control Offer as would be material to a Holder
     of Securities in connection with the decision of such Holder as to
     whether or not it should tender Securities pursuant to the Change of
     Control Offer.

          On the Change of Control Purchase Date, the Company shall

shall promptly authenticate and mail or deliver to such Holders a new
Security equal in principal amount to any unpurchased portion of any Security
surrendered.  Any Securities not so accepted shall be promptly mailed or
delivered by the Company to the Holder thereof.  The Company will publicly
announce the results of the Change of Control Offer not later than the first
Business Day following the Change of Control Purchase Date.

          The Company shall not be required to make a Change of Control Offer
upon a Change of Control if a third party makes the Change of Control Offer
in the manner, at the times and otherwise in compliance with the requirements
applicable to a Change of Control Offer made by the Company and purchases all
Securities validly tendered and not withdrawn under such Change of Control
Offer.
<PAGE>

          The Company shall comply, to the extent applicable, with the
requirements of Section 14(e) of the Exchange Act, and any other securities
laws or regulations in the event that a Change of Control occurs and the
Company is required to purchase Securities pursuant to this Section 4.11.

          4.12.   Disposition of Proceeds of Asset Sales.

          (a)  The Company will not, and will not permit any of its
Subsidiaries to, make any Asset Sale unless (i) the Company or such
Subsidiary, as the case may be, receives consideration at the time of such
Asset Sale at least equal to the Fair Market Value of the shares or assets
sold or otherwise disposed of and (ii) at least 85% of such consideration
consists of cash or Cash Equivalents or the assumption of Indebtedness of the
Company or such Subsidiary or other obligations relating to such assets and
release from all liability on the Indebtedness or other obligations assumed,
unless, in the case of clause (ii), the remainder of such consideration
consists of (x) property or assets that will be owned by the Company or a
Subsidiary of the Company and are to be used in a telecommunications business
or related activities or services that thereafter will be conducted by the
Company or such Subsidiary or (y) Capital Stock or other securities issued by
a party to the transaction or an Affiliate thereof, which Capital Stock or
other securities are freely tradeable and which are sold for cash within 90
days of the consummation of the Asset Sale in connection with which they were
acquired.  The Company or such Subsidiary, as the case may be, may, within
180 days of such Asset Sale, apply such Net Cash Proceeds (or enter into a
binding agreement within such 180-day period to apply such Net Cash Proceeds
within 45 days of the date of such agreement) to (i) an investment in
properties and assets that replace the properties and assets that were the
subject of such Asset Sale or in properties and assets that will be used in
the business of the Company and its Subsidiaries existing on the Issue Date
or in businesses reasonably related thereto ("Replacement Assets") or (ii) in
the case of an Asset Sale by a Subsidiary of the Company, the repayment of
any Indebtedness of such Subsidiary.  Any Net Cash Proceeds from any Asset
Sale that are not invested in Replacement Assets within the 180-day period
described above constitute "Excess Proceeds" subject to disposition as
provided below.

          (b)  When the aggregate amount of Excess Proceeds exceeds
$10,000,000, the Company will make an offer (an "Asset Sale Offer") to all
Holders and all holders of Other Qualified Senior Notes, to be consummated
not more than 40 Business Days thereafter (the "Asset Sale Purchase Date"),
to purchase the maximum principal amount of Securities and Other Qualified
Senior Notes, on a pro rata basis according to the Accreted Value or
principal amount, as the case may be, of the Securities and the Other
Qualified Senior Notes that may be purchased out of the Excess Proceeds
(i) with respect to the Other Qualified Senior Notes, based on the terms set
forth in the instrument related to each issue of the Other Qualified Senior
Notes and (ii) with respect to the Securities, at an offer price (the "Asset
Sale Offer Price") in cash in an amount equal to 100% of the Accreted Value
on the date fixed for closing of such offer plus accrued and unpaid interest,
if any, to the date fixed for the closing of such offer in accordance with
the procedures set forth in this Section 4.12.  To the extent that the
aggregate Accreted Value or principal amount, as the case may be, of
Securities and Other Qualified Senior Notes tendered pursuant to an Asset
Sale Offer is less than the Excess Proceeds, the Company may use such
deficiency in the business of the Company and its Subsidiaries on the Issue
Date or in businesses reasonably related thereto (including for general
corporate purposes).  If the aggregate Accreted Value or principal amount, as
the case may be, of Securities and Other Qualified Senior Notes surrendered
by holders thereof exceeds the amount of Excess Proceeds, then the Excess
Proceeds will be allocated pro rata according to Accreted Value or principal
amount, as the case may be, to the Securities and each issue of the Other
Qualified Senior Notes and the Trustee will select the Securities to be
purchased from the amount allocated to the Securities on the basis set forth
in this Indenture.  Upon completion of such offer to purchase, the amount of
Excess Proceeds will be reset at zero.
<PAGE>

          (c)  Notice of an Asset Sale Offer shall be mailed by the Company
to all Holders not less than 20 Business Days nor more than 40 Business Days
before the Asset Sale Purchase Date at their last registered address with a
copy to the Trustee and the Paying Agent.  The Asset Sale Offer shall remain
open from the time of mailing for at least 20 Business Days and until at
least 5:00 p.m., New York City time, on the Asset Sale Purchase Date.  The
notice, which shall govern the terms of the Asset Sale Offer, shall include
such disclosures as are required by law and shall state:

            (i)   that the Asset Sale Offer is being made pursuant to this
     Section 4.12;

           (ii)   the Asset Sale Offer Price (including the amount of accrued
     interest, if any) for each Security, the Asset Sale Purchase Date and
     the date on which the Asset Sale Offer expires;

          (iii)   that any Security not tendered or accepted for payment will
     continue to accrue interest in accordance with the terms thereof;

           (iv)   that, unless the Company shall default in the payment of
     the Asset Sale Offer Price, any Security accepted for payment pursuant
     to the Asset Sale Offer shall cease to accrue interest after the Asset
     Sale Purchase Date;

            (v)   that Holders electing to have Securities purchased pursuant
     to an Asset Sale Offer will be required to surrender their Securities to
     the Paying Agent at the address specified in the notice prior to 5:00
     p.m., New York City time, on the Business Day immediately preceding the
     Asset Sale Purchase Date and must complete any form of letter of
     transmittal proposed by the Company and reasonably acceptable to the
     Trustee and the Paying Agent;

           (vi)   that Holders will be entitled to withdraw their election if
     the Paying Agent receives, not later than 5:00 p.m., New York City time,

     Date, a telex, facsimile transmission or letter setting forth the name
     of the Holder, the principal amount of Securities the Holder delivered
     for purchase, the Security certificate number (if any) and a statement
     that such Holder is withdrawing its election to have such Securities
     purchased;

          (vii)   that if Securities in a principal amount in excess of the
     Holder's pro rata share of the amount of Excess Proceeds are tendered
     pursuant to the Asset Sale Offer, the Company shall purchase Securities
     on a pro rata basis among the Securities tendered (with such adjustments
     as may be deemed appropriate by the Company so that only Securities in
     denominations of $1,000 principal amount at maturity or integral
     multiples of $1,000 shall be acquired);

         (viii)   that Holders whose Securities are purchased only in part
     will be issued new Securities equal in principal amount to the
     unpurchased portion of the Securities surrendered;

           (ix)   the instructions that Holders must follow in order to
     tender their Securities; and

            (x)   information concerning the business of the Company, the
     most recent annual and quarterly reports of the Company filed with the
     SEC pursuant to the Exchange Act (or, if the Company is not permitted to

     pursuant to Section 4.07), a description of material developments in the
     Company's business, information with respect to pro forma historical
     financial information after giving effect to such Asset Sale and Asset
     Sale Offer and such other information concerning the circumstances and
     relevant facts regarding such Asset Sale Offer as would be material to a
     Holder of Securities in connection with the decision of such Holder as
     to whether or not it should tender Securities pursuant to the Asset Sale
     Offer.

          (d)  On the Asset Sale Purchase Date, the Company shall (i) accept
for payment, on a pro rata basis, Securities or portions thereof tendered
pursuant to the Asset Sale Offer, (ii) deposit with the Paying Agent money,
in immediately available funds, in an amount sufficient to pay the Asset Sale
Offer Price of all Securities or portions thereof so tendered and accepted
<PAGE>

and (iii) deliver to the Trustee the Securities so accepted together with an
Officers' Certificate setting forth the Securities or portions thereof
tendered to and accepted for payment by the Company.  The Paying Agent shall
promptly mail or deliver to Holders of Securities so accepted payment in an
amount equal to the Asset Sale Offer Price for such Securities, and the
Trustee shall promptly authenticate and mail or deliver to such Holders a new
Security equal in principal amount to any unpurchased portion of any Security
surrendered.  Any Securities not so accepted shall be promptly mailed or
delivered by the Company to the Holder thereof.  The Company will publicly
announce the results of the Asset Sale Offer not later than the first
Business Day following the Asset Sale Purchase Date.  For purposes of this
Section 4.12, the Trustee shall act as Paying Agent.

          (e)  The Company shall comply, to the extent applicable, with the
requirements of Section 14(e) of the Exchange Act and any other securities
laws or regulations in the event that an Asset Sale occurs and the Company is
required to purchase Securities pursuant to this Section 4.12.

          4.13.   Limitation on Issuances and Sale
                  of Preferred Stock by Subsidiaries.

of the Company) and (b) will not permit any person (other than the Company or
a Wholly-Owned Subsidiary of the Company) to own any Preferred Stock of any
Subsidiary of the Company; provided that the terms of this Section 4.13 shall
not be violated by the acquisition by the Company of any person that will be
a Subsidiary of the Company upon the consummation of such acquisition and
that had Preferred Stock outstanding prior to such acquisition that was not
issued in anticipation of such acquisition.

          4.14.   Limitation on Transactions with
                  Interested Persons.            

          The Company will not, and will not permit any of its Subsidiaries
to, directly or indirectly, enter into or suffer to exist any transaction or
series of related transactions (including, without limitation, the sale,
transfer, disposition, purchase, exchange or lease of assets, property or
services) with, or for the benefit of, any Affiliate of the Company or any
beneficial owner (as such term is defined under the definition "Change of
Control" in this Indenture) of 10% or more of the Company's Common Stock at
any time outstanding (in each case, an "Interested Person"), unless (a) such
transaction or series of related transactions is on terms that are no less
favorable to the Company or such Subsidiary, as the case may be, than those
which could have been obtained in a comparable transaction at such time from
persons who are not Affiliates of the Company or Interested Persons, (b) with
respect to the sale of Capital Stock of the Company (other than Redeemable
Capital Stock) involving aggregate payments or value equal to or greater than

clause (c) (ii) has been delivered or that such transaction or series of
transactions have been approved by a majority of the Board of Directors of
the Company and by a majority of the Disinterested Directors; provided,
however, that this Section 4.14 will not restrict the Company or its

an Affiliate.

shall be deemed to be Indebtedness of the Company or such Subsidiary, as the
case may be, and (b) after giving pro forma effect to any such Sale-Leaseback
Transaction and the foregoing clause (a), the Company would be able to incur

          (a)  The Company shall cause (i) each of its wholly-owned direct
and indirect subsidiaries organized under the laws of a state of the United
States or the District of Columbia, doing business in the United States and
existing as of the date hereof, which such subsidiaries are listed on
Schedule 4.18 hereto and (ii) in accordance with paragraph (c) of this
Section 4.18, each of its subsidiaries that becomes such a wholly-owned
direct or indirect subsidiary subsequent to the date of this Indenture
(collectively, the "Guarantors") to jointly and severally guarantee the
obligations of the Company under the Securities, this Indenture, the Pledge
Agreements, the Note Pledge Agreements, the Security Agreements and any other
security arrangements pursuant to supplemental indentures ("Guarantees"),
which such Guarantees (i) shall be in form and substance reasonably
satisfactory to the Trustee and (ii) shall be executed and delivered by all
of the Guarantors in existence on the date of this Indenture (each a
"Presently Existing Guarantor") and shall be accompanied by an Opinion of
Counsel as to the enforceability thereof and such other matters as the
Trustee may reasonably request within 60 days after the date hereof.  At the
time any Guarantees are entered into, the Company shall additionally deliver
to the Trustee an Officers' Certificate (which such Officers' Certificate
shall be in form and substance reasonably satisfactory to the Trustee)
certifying that all Guarantees required to be delivered under the terms of
this Section 4.18 have been delivered and describing any acquisitions,
mergers, consolidations or sales of substantially all of the assets of or
with respect to the subsidiaries listed on Schedule 4.18 hereto.  To the
extent that the Company is unable to obtain the Guarantee of each Presently
Existing Guarantor within such 60-day period, the Company shall deposit with
the Paying Agent an aggregate amount of $500,000 in immediately available
funds on the 61st day (the "First Payment Date") after the date of this
Indenture, and an additional $500,000 on each succeeding 90th day after the
First Payment Date upon which all of such Guarantees have not been obtained,
which amounts the Paying Agent shall promptly mail or deliver on a pro rata
basis to Holders of record on each such date.
<PAGE>

          (b)  Notwithstanding the foregoing, no subsidiary of the Company
shall be required to become a Guarantor hereunder if and to the extent such
subsidiary either (i) is prohibited under applicable law (but not by the
terms of any contract, including, without limitation, any other indenture)
from becoming a Guarantor and compliance with any such law would be
materially burdensome to such Guarantor (and such subsidiary delivers an
Opinion of Counsel to the effect that such Guarantee is so prohibited) or
(ii) has assets with an aggregate Fair Market Value of less than $100,000 and
does not hold any Licenses (and such subsidiary delivers an Officers'
Certificate certifying thereto) and Cumulous Holding Corp., Inc. ("Cumulous")
shall not be required to become a Guarantor hereunder to the extent that
there shall be a contractual restriction in effect on the Issue Date
preventing it from becoming a Guarantor hereunder.

          (c)  To the extent that, after the date of this Indenture, the
Company establishes or acquires any additional wholly-owned direct and
indirect subsidiaries which are organized under the laws of a state of the
United States or the District of Columbia and which do business in the United
States, the Company shall promptly, but in no case later than 30 days after
the date of such establishment or acquisition, cause each such subsidiary to
jointly and severally guarantee the obligations of the Company under the
Securities, this Indenture, the Pledge Agreements, the Note Pledge
Agreements, the Security Agreements and any other security arrangements
pursuant to a Guarantee in form and substance satisfactory to the Trustee, to
the fullest extent provided herein and shall be accompanied by an Opinion of
Counsel as to the enforceability thereof and such other matters as the
Trustee may reasonably request.

          (d)  To the extent that any wholly-owned subsidiary of the Company
that is organized under the laws of a state of the United States or the
District of Columbia (other than Cumulous if it is not a Guarantor) is not
required to execute and deliver a Guarantee as contemplated above, the
Company hereby covenants that such subsidiary shall not engage in any
business activities in the United States or hold any License.  To the extent
any such subsidiary engages in such business activities or holds any License
at such time, the Company shall cause such business activities to be ceased
promptly and/or such Licenses to be transferred (and the Company will use its
best efforts to cause any Licenses to be so transferred), as soon as
practicable, to a Guarantor.

          (e)  Upon the execution and delivery of a Guarantee, each Guarantor
hereby agrees as follows:

               (i)   The obligations of each Guarantor pursuant to its
         Guarantee will be subordinated in right of repayment to any
         obligation of such Guarantor pursuant to any Indebtedness incurred
         by such Guarantor to finance the construction or acquisition of
         Telecommunications Assets by such Guarantor for use by such
         Guarantor in the United States.  The obligations of each Guarantor
         pursuant to its Guarantee shall be pari passu or senior in right of
         repayment to all other obligations of such Guarantor.

               (ii)  Subject to the terms and conditions of paragraph (iii)
         of this Section 4.18(e), such Guarantor may not consolidate or merge
         with or into (whether or not such Guarantor is the surviving
         entity), or sell, assign, transfer, lease, convey or otherwise
         dispose of all or substantially all of its properties or assets in
         one or more related transactions to another person unless:

               (A) such Guarantor is the surviving person or the person
                   formed by or surviving any such consolidation or merger
                   (if other than such Guarantor) or the person to which such
                   sale, assignment, transfer, lease, conveyance or other
                   disposition will have been made is a corporation organized
                   or existing under the laws of the United States, any state
                   thereof or the District of Columbia;
<PAGE>

               (B) the person formed by or surviving any such consolidation
                   or merger (if other than such Guarantor) or the person to
                   which such sale, assignment, transfer, lease, conveyance
                   or other disposition will have been made assumes all the
                   obligations of such Guarantor, pursuant to a supplemental
                   indenture which shall be in form and substance reasonably
                   satisfactory to the Trustee and shall be accompanied by an
                   Opinion of Counsel as to the enforceability thereof, under
                   the Securities and this Indenture;

               (C) no Default or Event of Default shall have occurred and be
                   continuing on the date of such transaction or shall occur
                   as a result of such transaction; and

               (D) Such Guarantor or the person formed by or surviving any
                   such consolidation or merger, or the person to which such
                   sale, assignment, transfer, lease, conveyance or other
                   disposition will have been made (i) will have Consolidated
                   Net Worth immediately after the transaction (but prior to
                   any purchase accounting adjustments or accrual of deferred
                   tax liabilities resulting from the transaction) not less
                   than the Consolidated Net Worth of such Guarantor
                   immediately preceding the transaction and (ii) will have
                   an Indebtedness to Annualized Operating Cash Flow Ratio
                   immediately after the transaction that does not exceed
                   such Guarantor's Indebtedness to Annualized Operating Cash
                   Flow Ratio immediately preceding the transaction in
                   respect of the same period.

               (E) In case of any such consolidation, merger, sale or
                   conveyance and upon the assumption by the successor
                   corporation, by supplemental indenture, executed and
                   delivered to the Trustee and satisfactory in form to the
                   Trustee, of this Guarantee and the due and punctual
                   performance of all of the covenants and conditions of this
                   Indenture to be performed by the Guarantor, such successor
                   corporation shall succeed to and be substituted for the
                   Guarantor with the same effect as if it had been named
                   herein as a Guarantor.  Such successor corporation
                   thereupon may cause to be signed any Guarantees to be
                   endorsed upon the Securities issuable hereunder which
                   heretofore shall not have been signed by the Company and
                   delivered to the Trustee.  Such Guarantee shall in all
                   respects have the same legal rank and benefit under this
                   Indenture as the Guarantees theretofore and thereafter
                   issued in accordance with the terms of this Indenture as
                   though all of such Guarantees had been issued at the same
                   date.

               (iii) Except as set forth in Articles Four and Five of this
         Indenture, nothing contained in this Indenture shall prevent any
         consolidation or merger of a Guarantor with or into the Company or
         shall prevent any sale or conveyance of the property of a Guarantor
         as an entirety or substantially as an entirety to the Company.

               (iv)  In the event of a sale or other disposition of all of
         the assets of such Guarantor, by way of merger, consolidation or
         otherwise or a sale or other disposition of all of the Capital Stock
         of such Guarantor (other than to a Subsidiary of the Company), then
         such Guarantor (in the event of a sale or other disposition, by way
         of such merger, consolidation or otherwise, of all of the Capital
         Stock of such Guarantor) or the person acquiring the property (in
         the event of a sale or other disposition of all of the assets of
         such Guarantor) will be released and relieved of any obligations
         under its Guarantee, provided that the proceeds of such sale or
         other disposition are applied in accordance with the provisions of
         Section 4.12 of this Indenture.  Upon delivery by the Company to the
<PAGE>

         Trustee of an Officers' Certificate and an Opinion of Counsel to the
         effect that such sale or other disposition was made by the Company
         in accordance with the provisions of this Indenture, including
         without limitation Section 4.12, the Trustee shall execute any
         documents reasonably required in order to evidence the release of
         any Guarantor from its obligations under its Guarantee.  Any
         Guarantor not released from its obligations under its Guarantee
         shall remain liable for the full amount of principal of and interest
         on the Securities and for the other obligations of any Guarantor
         under the Indenture.

               (v)   Such Guarantor shall agree jointly and severally and
         unconditionally to guarantee to each Holder of a Security
         authenticated and delivered by the Trustee and to the Trustee and
         its successors and assigns, irrespective of the validity and
         enforceability of this Indenture, the Securities, the Pledge
         Agreements, the Note Pledge Agreements, the Security Agreements or
         any other security arrangements or the obligations of the Company
         hereunder or thereunder, that:  (a) the Accreted Value of and
         interest on the Securities will be promptly paid in full when due,
         whether at Stated Maturity, by acceleration, redemption or
         otherwise, and interest on the overdue principal of and interest on
         the Securities, if any, if lawful, and all other obligations of the
         Company to the Holders or the Trustee hereunder or thereunder will
         be promptly paid in full or performed, all in accordance with the
         terms hereof and thereof; and (b) in case of any extension of time
         of payment or renewal of any Securities or any of such other
         obligations, that same will be promptly paid in full when due or
         performed in accordance with the terms of the extension or renewal,
         whether at Stated Maturity, by acceleration or otherwise.  Failing
         payment when due of any amount so guaranteed or any performance so
         guaranteed for whatever reason, such Guarantor will be jointly and
         severally obligated to pay the same immediately.  Such Guarantor
         shall agree that its obligations under such Guarantee shall be
         unconditional, irrespective of the validity, regularity or
         enforceability of the Securities, this Indenture, the Pledge
         Agreements, the Note Pledge Agreements, the Security Agreements or
         any other security arrangements, the absence of any action to
         enforce the same, any waiver or consent by any Holder of the
         Securities with respect to any provisions hereof or thereof, the
         recovery of any judgment against the Company, any action to enforce
         the same or any other circumstance which might otherwise constitute
         a legal or equitable discharge or defense of a Guarantor.  Such
         Guarantor shall waive diligence, presentment, demand of payment,
         filing of claims with a court in the event of insolvency or
         bankruptcy of the Company, any right to require a proceeding first
         against the Company, protest, notice and all demands whatsoever and
         covenant that such Guarantee will not be discharged except by
         complete performance of the obligations contained in the Securities
         and this Indenture or in accordance with Section 10.12 and Section
         4.18(f) hereof.  If any Holder or the Trustee is required by any
         court or otherwise to return to the Company or any Guarantor, or any
         Custodian, Trustee, liquidator or other similar official acting in
         relation to either the Company or any Guarantor, any amount paid by
         either to the Trustee or such Holder, such Guarantor's guarantee, to
         the extent theretofore discharged, shall be reinstated in full force
         and effect.  Such Guarantor shall agree that it shall not be
         entitled to any right of subrogation in relation to the Holders in
         respect of any obligations guaranteed.  Such Guarantor shall further
         agree that, as between such Guarantor, on the one hand, and the
         Holders and the Trustee, on the other hand, (x) the maturity of the
         obligations guaranteed may be accelerated as provided in Article Six
         hereof for the purposes of such Guarantee, notwithstanding any stay,
         injunction or other prohibition preventing such acceleration in
         respect of the obligations guaranteed, and (y) in the event of any
         declaration of acceleration of such obligations as provided in
         Article Six, such obligations (whether or not due and payable) shall
         forthwith become due and payable by such Guarantor for the purpose
         of such Guarantee.
<PAGE>

               (vi)  Each Guarantee shall provide that, in the event that
         such Guarantee would constitute or result in a violation of any
         applicable fraudulent conveyance or similar law of any relevant
         jurisdiction, the liability of the applicable Guarantor under such
         Guarantee shall be reduced to the maximum amount permissible under
         such fraudulent conveyance or similar law.

          (f)  In the event (i) Holders of 66 2/3% or more of the aggregate
principal amount at maturity of the Securities outstanding on a Collateral
Release Request Date consent thereto or (ii) upon the consummation of a
Collateral Release Offer, in either case, in accordance with the terms,
conditions and procedures set forth in Section 10.12 hereof, then the
Guarantees shall automatically terminate and the Company shall have no
further obligations under this Section 4.18.

          4.19.   Waiver of Stay, Extension or Usury Laws.

          The Company covenants (to the extent that it may lawfully do so)
that it will not at any time insist upon, or plead, or in any manner
whatsoever claim or take the benefit or advantage of, any stay or extension
law or any usury law or other law which would prohibit or forgive the Company
from paying all or any portion of the principal of, premium, if any, or
interest on the Securities as contemplated herein, wherever enacted, now or
at any time hereafter in force, or which may affect the covenants or the
performance of this Indenture; and (to the extent that it may lawfully do so)
the Company hereby expressly waives  all benefit or advantage of any such
law, and covenants that it will not hinder, delay or impede the execution of
any power herein granted to the Trustee, but will suffer and permit the
execution of every such power as though no such law had been enacted.

                                  ARTICLE FIVE

                             SUCCESSOR CORPORATION

          5.01.   When Company May Merge, etc.

          The Company will not, in any transaction or series of transactions,
merge or consolidate with or into, or sell, assign, convey, transfer, lease
or otherwise dispose of all or substantially all of its properties and assets
as an entirety to, any person or persons, and the Company will not permit any
of its Subsidiaries to enter into any such transaction or series of
transactions if such transaction or series of transactions, in the aggregate,
would result in a sale, assignment, conveyance, transfer, lease or other
disposition of all or substantially all of the properties and assets of the
Company or the Company and its Subsidiaries, taken as a whole, to any other
person or persons, unless at the time of and after giving effect thereto
(a) either (i) if the transaction or series of transactions is a merger or
consolidation, the Company shall be the surviving person of such merger or
consolidation, or (ii) the person formed by such consolidation or into which
the Company or such Subsidiary is merged or to which the properties and
assets of the Company or such Subsidiary, as the case may be, are transferred
(any such surviving person or transferee person being the "Surviving Entity")
shall be a corporation organized and existing under the laws of the United
States of America, any state thereof or the District of Columbia and shall
expressly assume by a supplemental indenture executed and delivered to the
Trustee, in form reasonably satisfactory to the Trustee, all the obligations
of the Company under the Securities and this Indenture, and in each case,
this Indenture shall remain in full force and effect; (b) immediately before
and immediately after giving effect to such transaction or series of
transactions on a pro forma basis (including, without limitation, any
Indebtedness incurred or anticipated to be incurred in connection with or in
respect of such transaction or series of transactions), no Default or Event
of Default shall have occurred and be continuing and the Company or the
Surviving Entity, as the case may be, after giving effect to such transaction
or series of transactions on a pro forma basis (including, without
limitation, any Indebtedness incurred or anticipated to be incurred in
connection with or in respect of such transaction or series of transactions),
<PAGE>

could incur $1.00 of additional Indebtedness pursuant to the first paragraph
of Section 4.08 (assuming a market rate of interest with respect to such
additional Indebtedness); and (c) immediately after giving effect to such
transaction or series of transactions on a pro forma basis (including,
without limitation, any Indebtedness incurred or anticipated to be incurred
in connection with or in respect of such transaction or series of
transactions), the Consolidated Net Worth of the Company or the Surviving
Entity, as the case may be, is at least equal to the Consolidated Net Worth
of the Company immediately before such transaction or series of transactions.

          In connection with any consolidation, merger, transfer, lease,
assignment or other disposition contemplated hereby, the Company shall
deliver, or cause to be delivered, to the Trustee, in form and substance
reasonably satisfactory to the Trustee, an Officer's Certificate and an
Opinion of Counsel, each stating that such consolidation, merger, transfer,
lease, assignment or other disposition and the supplemental indenture in
respect thereof comply with the requirements under this Indenture; provided,
however, that solely for purposes of computing amounts described in subclause
(d)(iii) of Section 4.09, any such successor person shall only be deemed to
have succeeded to and be substituted for the Company with respect to periods
subsequent to the effective time of such merger, consolidation or transfer of
assets.

          5.02.   Successor Substituted.

          Upon any consolidation or merger, or any sale, assignment,
conveyance, transfer, lease or disposition of all or substantially all of the
properties and assets of the Company in accordance with Section 5.01 hereof,
the successor person or persons formed by such consolidation or into which
the Company is merged or the successor person to which such sale, assignment,
conveyance, transfer, lease or other disposition is made, shall succeed to,
and be substituted for, and may exercise every right and power of, the
Company under this Indenture and the Securities with the same effect as if
such successor had been named as the Company herein; provided, however, that
solely for purposes of computing amounts described in subclause (c) of
Section 4.09, any such successor person shall only be deemed to have
succeeded to and be substituted for the Company with respect to periods
subsequent to the effective time of such merger, consolidation or transfer of
assets.

                                  ARTICLE SIX

     scheduled principal payment or otherwise); or

          (b)  a default in the payment of an installment of interest on any
     of the Securities, when the same becomes due and payable, which default

     Trustee by Holders of at least 25% in aggregate principal amount of the
     Securities then outstanding; or

     then has outstanding Indebtedness in excess of $5,000,000, individually
     or in the aggregate, and either (i) such Indebtedness is already due and
     payable in full other than by reason of an acceleration or (ii) such
     default or defaults have resulted in the acceleration of the maturity of
     such Indebtedness and such acceleration has not been rescinded within a

     discharged or fully bonded and there shall have been a period of 60 days
     after the date on which any period for appeal has expired and during
     which a stay of enforcement of such judgment, order or decree, shall not

          generally; or

          (g)  a court of competent jurisdiction enters an order or decree
     under any Bankruptcy Law that:
               (i)  is for relief against the Company or any Significant

     obligations under its Guarantee.

          Subject to the provisions of Sections 7.01 and 7.02, the Trustee

Corporate Trust Office of the Trustee by the Company, the Paying Agent, any
Holder or any of their respective agents.

          6.02.   Acceleration.

          If an Event of Default (other than as specified in Section 6.01(f)
or (g)) occurs and is continuing, the Trustee, by written notice to the
Company, or the Holders of at least 25% in aggregate principal amount of the
Securities then outstanding, by written notice to the Trustee and the
Company, may declare the Accreted Value of, premium, if any, and accrued and
unpaid interest, if any, on all of the outstanding Securities to be due and
payable immediately, upon which declaration, all amounts payable in respect
of the Securities shall be immediately due and payable.  If an Event of
Default specified in Section 6.01(f) or (g) occurs and is continuing, then
the Accreted Value of, premium, if any, and accrued and unpaid interest, if
any, on all of the Securities shall ipso facto become and be immediately due
and payable without any declaration or other act on the part of the Trustee
or any Holder.

          After a declaration of acceleration under this Indenture, but
before a judgment or decree for payment of the money due has been obtained by
the Trustee, the Holders of a majority in aggregate principal amount of the
outstanding Securities, by written notice to the Company and the Trustee, may
rescind such declaration if (a) the Company has paid or deposited with the
Trustee a sum sufficient to pay (i) all amounts due the Trustee under Section
7.08 and the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel, (ii) all overdue interest on all
Securities, (iii) the Accreted Value of and premium, if any, on any
<PAGE>

Securities which have become due otherwise than by such declaration of
acceleration and interest thereon at the rate borne by the Securities, and
(iv) to the extent that payment of such interest is lawful, interest upon
overdue interest which has become due otherwise than by such declaration of
acceleration at the rate borne by the Securities; (b) the rescission would
not conflict with any judgment or decree of a court of competent
jurisdiction; and (c) all Events of Default, other than the non-payment of
Accreted Value of, premium, if any, and interest on the Securities that have
become due solely by such declaration of acceleration, have been cured or
waived as provided in Section 6.04.

          No such rescission shall affect any subsequent Default or Event of
Default or impair any right subsequent therein.

          6.03.   Other Remedies.

          If an Event of Default occurs and is continuing, the Trustee may
pursue any available remedy by proceeding at law or in equity to collect the
payment of principal of, premium, if any, or interest on the Securities or to
enforce the performance of any provision of the Securities, this Indenture or
any of the Pledge Agreements.

          All rights of action and claims under this Indenture, the
Securities and the Pledge Agreements may be enforced by the Trustee even if
it does not possess any of the Securities or does not produce any of them in
the proceeding.  A delay or omission by the Trustee or any Holder in
exercising any right or remedy accruing upon an Event of Default shall not
impair the right or remedy or constitute a waiver of or acquiescence in the
Event of Default.  No remedy is exclusive of any other remedy.  All available
remedies are cumulative to the extent permitted by law.

          6.04.   Waiver of Past Defaults.

          Subject to the provisions of Sections 6.07 and 9.02, the Holders of
not less than a majority in aggregate principal amount of the outstanding
Securities by notice to the Trustee may, on behalf of the Holders of all the
Securities, waive any existing Default or Event of Default and its
consequences, except a Default or Event of Default specified in Section
6.01(a) or (b) or in respect of any provision hereof which cannot be modified
or amended without the consent of the Holder of each outstanding Security
affected thereby pursuant to Section 9.02.  When a Default or Event of
Default is so waived, it shall be deemed cured and shall cease to exist.

          6.05.   Control by Majority.

          The Holders of not less than a majority in aggregate principal
amount of the outstanding Securities shall have the right to direct the time,
method and place of conducting any proceeding for any remedy available to the
Trustee, or exercising any trust or power conferred on the Trustee, provided,
however, that the Trustee may refuse to follow any direction (a) that
conflicts with any rule of law or this Indenture, (b) that the Trustee
determines may be unduly prejudicial to the rights of another Securityholder,
or (c) that may expose the Trustee to personal liability unless the Trustee
has been provided reasonable indemnity against any loss or expense caused by
its following such direction; and provided, further, that the Trustee may
take any other action deemed proper by the Trustee that is not inconsistent
with such direction.

          6.06.   Limitation on Suits.

          No Holder shall have any right to institute any proceeding or
pursue any remedy with respect to this Indenture, the Securities or any of
the Pledge Agreements unless:
          (a)  Holders of at least 25% in aggregate principal amount of the
     outstanding Securities make a written request to the Trustee to
     institute such proceeding or pursue such remedy;
          (b)  such Holders offer and, if requested, provide to the Trustee
     reasonable indemnity against any loss, liability or expense;
          (c)  the Trustee fails to institute such proceeding or pursue such
     remedy within 60 days after receipt of such request; and
          (d)  within such 60-day period the Trustee does not receive a
     direction which is inconsistent with the request from the Holders of a
     majority in aggregate principal amount of the outstanding Securities;
<PAGE>

          The foregoing limitations shall not apply to a suit instituted by a
Holder for the enforcement of the payment of principal of, premium, if any,
or accrued interest on, such Security on or after the respective due dates
set forth in such Security, subject to applicable grace periods.

          A Holder may not use this Indenture to prejudice the rights of any
other Holders or to obtain priority or preference over such other Holders.

          6.07.   Right of Holders To Receive Payment.

          Notwithstanding any other provision in this Indenture, the right of
any Holder to receive payment of the principal of, premium, if any, and
interest on such Security, on or after the respective Stated Maturities
expressed in such Security, or to bring suit for the enforcement of any such
payment on or after the respective Stated Maturities, is absolute and
unconditional and shall not be impaired or affected without the consent of
the Holder.

          6.08.   Collection Suit by Trustee.

          If an Event of Default specified in clause (a) or (b) of Section
6.01 occurs and is continuing, the Trustee may recover judgment in its own
name and as trustee of an express trust against the Company, or any other
obligor on the Securities for the whole amount of Accreted Value of, premium,
if any, and accrued interest remaining unpaid, together with interest on
overdue principal and, to the extent that payment of such interest is lawful,
interest on overdue installments of interest, in each case at the rate per
annum borne by the Securities and such further amount as shall be sufficient
to cover the costs and expenses of collection, including the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel.

          6.09.   Trustee May File Proofs of Claims.

          The Trustee may file such proofs of claim and other papers or
documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel) and the
Holders allowed in any judicial proceedings relative to the Company or the
Subsidiaries of the Company (or any other obligor upon the Securities), their
creditors or their property and shall be entitled and empowered to collect
and receive any monies or other property payable or deliverable on any such
claims and to distribute the same, and any Custodian in any such judicial
proceedings is hereby authorized by each Holder to make such payments to the
Trustee and, in the event that the Trustee shall consent to the making of
such payments directly to the Holders, to pay to the Trustee any amount due
to it for the reasonable compensation, expenses, disbursements and advances
of the Trustee, its agent and counsel, and any other amounts due the Trustee
under Section 7.08.  Nothing herein contained shall be deemed to authorize
the Trustee to authorize or consent to or accept or adopt on behalf of any
Holder any plan of reorganization, arrangement, adjustment or composition
affecting the Securities or the rights of any Holder thereof, or to authorize
the Trustee to vote in respect of the claim of any Holder in any such
proceeding.

          6.10.   Priorities.

          If the Trustee collects any money pursuant to this Article Six, it
shall pay out such money in the following order:
          First:  to the Trustee for amounts due under Section 7.08;
          Second:  to Holders for interest accrued on the Securities,
ratably, without preference or priority of any kind, according to the amounts
due and payable on the Securities for interest;
          Third:  to Holders for amounts of Accreted Value (including any
premium) owing under the Securities, ratably, without preference or priority
of any kind, according to the amounts due and payable on the Securities for
Accreted Value (including any premium); and
          Fourth:  the balance, if any, to the Company.

          The Trustee, upon prior written notice to the Company, may fix a
record date and payment date for any payment to Securityholders pursuant to
this Section 6.10.
<PAGE>

          6.11.   Undertaking for Costs.

          In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted
by it as Trustee, a court may in its discretion require the filing by any
party litigant in the suit of an undertaking to pay the costs of the suit,
and the court in its discretion may assess reasonable costs, including
reasonable attorneys' fees, against any party litigant in the suit, having
due regard to the merits and good faith of the claims or defenses made by the
party litigant.  This Section 6.11 does not apply to any suit by the Trustee,
any suit by a Holder pursuant to Section 6.07, or a suit by Holders of more
than 10% in aggregate principal amount of the outstanding Securities.

          6.12.   Restoration of Rights and Remedies.

          If the Trustee or any Holder has instituted any proceeding to
enforce any right or remedy under this Indenture or any Security and such
proceeding has been discontinued or abandoned for any reason, or has been
determined adversely to the Trustee or to such Holder, then and in every such
case the Company, the Trustee and the Holders shall, subject to any
determination in such proceeding, be restored severally and respectively to
their former positions hereunder, and thereafter all rights and remedies of
the Trustee and the Holders shall continue as though no such proceeding had
been instituted.

                                 ARTICLE SEVEN

                                    TRUSTEE

          7.01.   Duties.

          (a)  In case an Event of Default has occurred and is continuing,
the Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a
prudent person would exercise or use under the circumstances in the conduct
of such person's own affairs.

          (b)  Except during the continuance of an Event of Default,

            (i)   the Trustee need perform only such duties as are
     specifically set forth in this Indenture, and no implied covenants or
     obligations shall be read into this Indenture against the Trustee; and

           (ii)   in the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness
     of the opinions expressed therein, upon certificates or opinions
     furnished to the Trustee and conforming to the requirements of this
     Indenture; but in the case of any such certificates or opinions which by
     any provision hereof are specifically required to be furnished to the
     Trustee, the Trustee shall be under a duty to examine the same to
     determine whether or not they conform as to form only to the
     requirements of this Indenture.

          (c)  No provision of this Indenture shall be construed to relieve
the Trustee from liability for its own negligent action, its own negligent
failure to act, or its own willful misconduct, except that

            (i)   this paragraph does not limit the effect of paragraph (b)
     of this Section 7.01;

           (ii)   the Trustee shall not be liable for any error of judgment
     made in good faith by a Trust Officer, unless it is proved that the
     Trustee was negligent in ascertaining the pertinent facts;

          (iii)   the Trustee shall not be liable with respect to any action
     it takes or omits to take in good faith in accordance with a direction
     received by it pursuant to Section 6.05.

          (d)  No provision of this Indenture shall require the Trustee to
expend or risk its own funds or otherwise incur any financial liability in
the performance of any of its duties hereunder or in the exercise of any of
its rights or powers if it shall have reasonable grounds for believing that
repayment of such funds or adequate indemnity against such risk or liability
is not reasonably assured to it.
<PAGE>

          (e)  Every provision of this Indenture that in any way relates to
the Trustee is subject to paragraphs (a), (b), (c) and (d) of this
Section 7.01.

          7.02.   Rights of Trustee.

          Subject to Section 7.01 hereof and the provisions of TIA * 315:
          (a)  the Trustee may rely on any document reasonably believed by it
     to be genuine and to have been signed or presented by the proper person.
     The Trustee need not investigate any fact or matter stated in the
     document.
          (b)  before the Trustee acts or refrains from acting, it may
     consult with counsel and may require an Officers' Certificate or an
     Opinion of Counsel, which shall conform to Sections 11.04 and 11.05.
     The Trustee shall not be liable for any action it takes or omits to take
     in good faith in reliance on such certificate or opinion.
          (c)  the Trustee may act through its attorneys and agents and shall
     not be responsible for the misconduct or negligence of any agent
     appointed with due care.
          (d)  the Trustee shall not be liable for any action taken or
     omitted by it in good faith and reasonably  believed by it to be
     authorized or within the discretion, rights or powers conferred upon it
     by this Indenture other than any liabilities arising out of its own
     negligence or willful misconduct.
          (e)  the Trustee may consult with counsel of its own choosing and
     the advice or opinion of such counsel as to matters of law shall be full
     and complete authorization and protection in respect of any action
     taken, omitted or suffered by it hereunder in good faith and in
     accordance with the advice or opinion of such counsel.
          (f)  the Trustee shall not be bound to make any investigation into
     the facts or matters stated in any resolution, certificate, statement,
     instrument, opinion, notice, request, direction, consent, order, bond,
     debenture, or other paper or document, but the Trustee, in its
     discretion, may make such further inquiry or investigation into such
     facts or matters as it may see fit.
          (g)  the Trustee shall be under no obligation to exercise any of
     the rights or powers vested in it by this Indenture at the request,
     order or direction of any of the Holders pursuant to the provisions of
     this Indenture, unless such Holders shall have offered to the Trustee
     reasonable security or indemnity against the costs, expenses and
     liabilities which may be incurred therein or thereby.

          7.03.   Individual Rights of Trustee.

          The Trustee, any Paying Agent, Registrar or any other agent of the
Company, in its individual or any other capacity, may become the owner or
pledgee of Securities and, subject to Sections 7.11 and 7.12 and TIA ** 310
and 311, may otherwise deal with the Company and its Subsidiaries with the
same rights it would have if it were not the Trustee, Paying Agent, Registrar
or such other agent.

          7.04.   Trustee's Disclaimer.

          The Trustee makes no representations as to the validity or
sufficiency of this Indenture or of the Securities, it shall not be
accountable for the Company's use or application of the proceeds from the
Securities, it shall not be responsible for the use or application of any
money received by any Paying Agent other than the Trustee and it shall not be
responsible for any statement in the Securities other than the Trustee's
certificate of authentication.

          7.05.   Notice of Default.

          If a Default or an Event of Default occurs and is continuing and if
it is known to the Trustee, the Trustee shall mail to each Holder notice of
the Default or Event of Default within 30 days after obtaining knowledge
thereof; provided, however, that, except in the case of a Default or Event of
Default specified in Section 6.01(a) or (b), the Trustee shall be protected
in withholding such notice if and so long as a committee of Trust Officers in
good faith determines that the withholding of such notice is in the interest
of the Holders.
<PAGE>

          7.06.   Money Held in Trust.

          All moneys received by the Trustee shall, until used or applied as
herein provided, be held in trust for the purposes for which they were
received, but need not be segregated from other funds except to the extent
required herein or by law.  The Trustee shall not be under any liability for
interest on any moneys received by it hereunder, except as the Trustee may
agree with the Company.

          7.07.   Reports by Trustee to Holders.

          Within 60 days after each May 15 beginning with the May 15
following the date of this Indenture, the Trustee shall, to the extent that
any of the events described in TIA * 313(a) shall have occurred within the
previous twelve months, but not otherwise, mail to each Holder a brief report
dated as of such May 15 that complies with TIA * 313(a).  The Trustee also
shall comply with TIA ** 313(b) and 313(c).

          A copy of each report at the time of its mailing to Holders shall
be mailed to the Company and filed with the SEC and each securities exchange,
if any, on which the Securities are listed.

          The Company shall notify the Trustee in writing if the Securities
become listed on any securities exchange.

          7.08.   Compensation and Indemnity.

          The Company covenants and agrees to pay the Trustee from time to
time reasonable compensation for its services.  The Trustee's compensation
shall not be limited by any law on compensation of a trustee of an express
trust.  The Company shall reimburse the Trustee upon request for all
reasonable disbursements, expenses and advances incurred or made by it.  Such
expenses shall include the reasonable compensation, disbursements and
expenses of the Trustee's agents, accountants and counsel.

          The Company shall indemnify the Trustee and its officers and
directors for, and hold it harmless against, any loss or liability incurred
by it arising out of or in connection with the administration of this trust
and its rights or duties hereunder, including the costs and expenses,
including reasonable attorneys' fees, of defending itself against any claim
or liability in connection with the exercise or performance of any of its
powers or duties hereunder.  The Trustee shall notify the Company promptly of
any claim asserted against the Trustee for which it may seek indemnity.  The
Company shall defend the claim and the Trustee shall reasonably cooperate in
the defense.  The Trustee may have separate counsel and the Company shall pay
the reasonable fees and expenses of such counsel.  The Company need not pay
for any settlement made without its prior written consent.  The Company need
not reimburse any expense or indemnify against any loss or liability to the
extent incurred by the Trustee through its negligence, bad faith or willful
misconduct.

          To secure the Company's payment obligations in this Section 7.08,
the Trustee shall have a Lien prior to the Securities on all assets held or
collected by the Trustee, in its capacity as Trustee, except assets held in
trust to pay principal of, premium, if any, or interest on particular
Securities.

          When the Trustee incurs expenses or renders services in connection
with an Event of Default specified in Section 6.01(f) or (g), the expenses
and the compensation for the services are intended to constitute expenses of
administration under any Bankruptcy Law.
          The Company's obligations under this Section 7.08 and any Lien
arising hereunder and under any of the Pledge Agreements shall survive the
resignation or removal of any trustee, the discharge of the Company's
obligations pursuant to Article Eight and/or the termination of this
Indenture.

          7.09.   Replacement of Trustee.

          The Trustee may resign by so notifying the Company.  The Holders of
a majority in principal amount of the outstanding Securities may remove the
Trustee by so notifying the Company and the Trustee and may appoint a
successor trustee with the Company's prior written consent.  The Company may
remove the Trustee if:

          1.   the Trustee fails to comply with Section 7.11;
<PAGE>

          2.   the Trustee is adjudged a bankrupt or an insolvent or an order
     for relief is entered with respect to the Trustee under any Bankruptcy
     Law;

          3.   a receiver or other public officer takes charge of the Trustee
     or its property; or

          4.   the Trustee becomes incapable of acting.

          If the Trustee resigns or is removed or if a vacancy exists in the
office of Trustee for any reason, the Company shall notify each Holder of
such event and shall promptly appoint a successor Trustee.  The Trustee shall
be entitled to payment of its fees and reimbursement of its expenses while
acting as Trustee, and to the extent such amounts remain unpaid, the Trustee
that has resigned or has been removed shall retain the Lien afforded by
Section 7.08.  Within one year after the successor Trustee takes office, the
Holders of a majority in principal amount of the outstanding Securities may,
with the Company's prior written consent, appoint a successor Trustee to
replace the successor Trustee appointed by the Company.

          A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company.  Immediately after
that, the retiring Trustee shall transfer all property held by it as Trustee
to the successor Trustee, subject to the Lien provided in Section 7.08, the
resignation or removal of the retiring Trustee shall become effective, and
the successor Trustee shall have all the rights, powers and duties of the
Trustee under this Indenture.  A successor Trustee shall mail notice of its
succession to each Securityholder.

          If a successor Trustee does not take office within 60 days after
the retiring Trustee resigns or is removed, the retiring Trustee, the Company
or the Holders of at least 10% in principal amount of the outstanding
Securities may petition any court of competent jurisdiction for the
appointment of a successor Trustee.

          If the Trustee fails to comply with Section 7.11, any Holder may
petition any court of competent jurisdiction for the removal of the Trustee
and the appointment of a successor Trustee.

          Notwithstanding replacement of the Trustee pursuant to this Section
7.09, the Company's obligations under Section 7.08 shall continue for the
benefit of the retiring Trustee.

          7.10.   Successor Trustee by Merger, etc.

          If the Trustee consolidates with, merges or converts into, or
transfers all or substantially all of its corporate trust business to,
another corporation or national banking association, the resulting, surviving
or transferee corporation or national banking association without any further
act shall, if such resulting, surviving or transferee corporation or national
banking association is otherwise eligible hereunder, be the successor
Trustee.

          7.11.   Eligibility; Disqualification.

          There shall at all times be a Trustee hereunder which shall be
eligible to act as Trustee under TIA ** 310(a)(1) and 310(a)(5) and which
shall have a combined capital and surplus of at least $50,000,000.  If such
corporation publishes reports of condition at least annually, pursuant to law
or to the requirements of federal, state, territorial or District of Columbia
supervising or examining authority, then for the purposes of this Section,
the combined capital and surplus of such corporation shall be deemed to be
its combined capital and surplus as set forth in its most recent report of
condition so published.  If at any time the Trustee shall cease to be
eligible in accordance with the provisions of this Section, the Trustee shall
resign immediately in the manner and with the effect hereinafter specified in
this Article.  The Trustee is subject to TIA * 310(b).

          7.12.   Preferential Collection of Claims
                  Against Company.                 

          The Trustee shall comply with TIA Section 311(a), excluding any
creditor relationship listed in TIA Section 311(b). If the present or any future
Trustee shall resign or be removed, it shall be subject to TIA Section 311(a) to
the extent provided therein.

                     SATISFACTION AND DISCHARGE; DEFEASANCE

          8.01.   Satisfaction and Discharge.

          This Indenture will be discharged and will cease to be of further
effect as to all outstanding Securities, except as to those obligations
referred to in the penultimate paragraph of this Section 8.01, when:

          (a)  either (i) all Securities theretofore authenticated and
     delivered (except lost, stolen or destroyed Securities which have been
     replaced or paid or Securities for whose payment money has theretofore
     been deposited with the Trustee or the Paying Agent in trust or
     segregated and held in trust by the Company and thereafter repaid to the
     Company or discharged from such trust, as provided in Section 8.04) have
     been delivered to the Trustee for cancellation, or (ii) all Securities
     not theretofore delivered to the Trustee for cancellation (except lost,
     stolen or destroyed Securities which have been replaced or paid) have
     been called for redemption pursuant to the terms of the Securities or
     have otherwise become due and payable hereunder;

          (b)  the Company shall have irrevocably deposited or caused to be
     deposited with the Trustee as trust funds in trust solely for the
     benefit of the Holders for that purpose, funds in an amount sufficient
     without consideration of reinvestment of such interest, to pay and
     discharge the entire Indebtedness on the Securities not theretofore
     delivered to the Trustee for cancellation for principal of, premium, if
     any, and interest on such Securities to the date of deposit together
     with irrevocable instructions from the Company directing the Trustee to
     apply such funds to the payment thereof at maturity or redemption, as
     the case may be;

          (c)  no Default or Event of Default with respect to this Indenture
     or the Securities shall have occurred and be continuing on the date of
     such deposit or shall occur as a result of such deposit;

          (d)  the Company shall have paid all other sums payable by it
     hereunder;

          (e)  the Company shall have delivered to the Trustee an Officers'
     Certificate and an Opinion of Counsel, each stating that all conditions
     precedent under this Section 8.01 have been complied with.

          Notwithstanding the foregoing paragraph, the Company's obligations
in Sections 2.05, 2.06, 2.07, 2.08, 4.01, 4.02  and 7.08 shall survive until
the Securities are no longer outstanding pursuant to Section 2.10.  After the
Securities are no longer outstanding, the Company's obligations in Sections
7.08, 8.03, 8.04 and 8.05 shall survive.

          After such delivery or irrevocable deposit the Trustee upon request
shall acknowledge in writing the discharge of the Company's obligations under
the Securities and this Indenture except for those surviving obligations
specified above.

          8.02.   Defeasance and Covenant Defeasance.

          (a)  The Company may, at its option and at any time, terminate the
obligations of the Company with respect to the outstanding Securities,
including, without limitation, all of the Company's obligations under the
Pledge Agreements, by electing to have either paragraph (b) or paragraph (c)
below be applied to the outstanding Securities upon compliance with the
conditions set forth in paragraph (d).

          (b)  Upon the Company's exercise under paragraph (a) of the option
applicable to this paragraph (b), the Company shall be deemed to have been
released and discharged from its obligations with respect to the outstanding
Securities, including, without limitation, all of the Company's obligations
under the Pledge Agreements, on the date the conditions set forth below are
satisfied (hereinafter, "defeasance").  For this purpose, such defeasance
means that the Company shall be deemed to have paid and discharged the entire
Indebtedness represented by the outstanding Securities, which shall
thereafter be deemed to be "outstanding" only for the purposes of
paragraph (e) below and the other Sections of and matters under this
Indenture referred to in (i) and (ii) below, and to have satisfied all its
other obligations under such Securities and this Indenture insofar as such
<PAGE>

Securities are concerned (and the Trustee, at the expense of the Company,
shall execute proper instruments acknowledging the same), except for the
following which shall survive until otherwise terminated or discharged
hereunder:  (i) the rights of Holders of outstanding Securities to receive
payments in respect of the principal of, premium, if any, and interest on
such Securities when such payments are due, (ii) the Company's obligations
with respect to such Securities under Sections 2.06, 2.07 and 4.02, and, with
respect to the Trustee, under Section 7.08, (iii) the rights, powers, trusts,
duties and immunities of the Trustee hereunder and (iv) this Article Eight.
Subject to compliance with this Section 8.02, the Company may exercise its
option under this paragraph (b) notwithstanding the prior exercise of its
option under paragraph (c) below with respect to the Securities.

          (c)  Upon the Company's exercise under paragraph (a) of the option
applicable to this paragraph (c), the Company shall be released and
discharged from its obligations under any covenant contained in Section 5.01
and in Sections 4.03 through 4.17 with respect to the outstanding Securities
and from its obligations under the Pledge Agreements on and after the date
the conditions set forth below are satisfied (hereinafter, "covenant
defeasance"), and the Securities shall thereafter be deemed to be not
"outstanding" for the purpose of any direction, waiver, consent or
declaration or act of Holders (and the consequences of any thereof) in
connection with such covenants or under the Pledge Agreements, but shall
continue to be deemed "outstanding" for all other purposes hereunder and
thereunder.  For this purpose, such covenant defeasance means that, with
respect to the outstanding Securities, the Company may omit to comply with
and shall have no liability in respect of any term, condition or limitation
set forth in any such covenant or under the Pledge Agreements, whether
directly or indirectly, by reason of any reference elsewhere herein to any
such covenant or by reason of any reference in any such covenant to any other
provision herein or in any other document and such omission to comply shall
not constitute a Default or an Event of Default under Section 6.01(c), but,
except as specified above, the remainder of this Indenture and such
Securities shall be unaffected thereby.

          (d)  The following shall be the conditions to application of either
paragraph (b) or paragraph (c) above to the outstanding Securities:

            (i)   the Company shall irrevocably have deposited or caused to
     be deposited with the Trustee as trust funds in trust for the purpose of
     making the following payments, specifically pledged as security for, and
     dedicated solely to, the benefit of the Holders of such Securities,
     (x) cash, in United States dollars, (y) direct non-callable obligations
     of, or non-callable obligations guaranteed by, the United States of
     America for the payment of which guarantee or obligation the full faith
     and credit of the United States is pledged ("U.S. Government
     Obligations"), or (z) a combination thereof, sufficient, in the opinion
     of a nationally recognized firm of independent public accountants
     expressed in a written certification thereof delivered to the Trustee,
     to pay and discharge, and which shall be applied by the Trustee to pay
     and discharge, the principal of, premium, if any, and interest on the
     outstanding Securities (except lost, stolen or destroyed Securities
     which have been replaced or repaid) to redemption or maturity, as the
     case may be, or otherwise in accordance with the terms of this Indenture
     and of such Securities;

           (ii)   no Default or Event of Default or event which with notice
     or lapse of time or both would become a Default or an Event of Default
     shall have occurred and be continuing on the date of such deposit or,
     insofar as Section 6.01(a) is concerned, at any time during the period
     ending on the 91st day after the date of such deposit (it being
     understood that this condition shall not be deemed satisfied until the
     expiration of such period);

          (iii)   such legal defeasance or covenant defeasance shall not
     cause the Trustee to have a conflicting interest with respect to any
     securities of the Company;

           (iv)   such legal defeasance or covenant defeasance shall not
     result in a breach or violation of, or constitute a Default or Event of
     Default under, this Indenture or any other material agreement or
     instrument to which the Company is a party or by which it is bound;
<PAGE>

            (v)   in the case of an election under paragraph (b) above, the
     Company shall have delivered to the Trustee an Opinion of Counsel
     stating that (x) the Company has received from, or there has been
     published by, the Internal Revenue Service a ruling or (y) since the
     date of this Indenture, there has been a change in the applicable
     Federal income tax law, in either case to the effect that, and based
     thereon such opinion shall confirm that, the Holders of the outstanding
     Securities will not recognize income, gain or loss for Federal income
     tax purposes as a result of such legal defeasance and will be subject to
     Federal income tax on the same amounts, in the same manner and at the
     same times as would have been the case if such legal defeasance had not
     occurred;

           (vi)   in the case of an election under paragraph (c) above, the
     Company shall have delivered to the Trustee an Opinion of Counsel to the
     effect that the Holders of the outstanding Securities will not recognize
     income, gain or loss for Federal income tax purposes as a result of such
     covenant defeasance and will be subject to Federal income tax on the
     same amounts, in the same manner and at the same times as would have
     been the case if such covenant defeasance had not occurred;

          (vii)   in the case of an election under either paragraph (b) or
     (c) above, the Company shall have delivered to the Trustee an Opinion of
     Counsel to the effect that, after the 91st day following the deposit,
     the trust funds will not be subject to the effect of any applicable
     bankruptcy, insolvency, reorganization or similar laws affecting
     creditors' rights generally; and

         (viii)   the Company shall have delivered to the Trustee an
     Officers' Certificate and an Opinion of Counsel, each stating that all
     conditions precedent under this Indenture to either the legal defeasance
     under paragraph (b) above or the covenant defeasance under paragraph (c)
     above, as the case may be, have been complied with.

          (e)  All money and U.S. Government Obligations (including the
proceeds thereof) deposited with the Trustee pursuant to paragraph (d) above
in respect of the outstanding Securities shall be held in trust and applied
by the Trustee, in accordance with the provisions of such Securities and this
Indenture, to the payment, either directly or through any Paying Agent (other
than the Company or any Affiliate of the Company) as the Trustee may
determine, to the Holders of such Securities of all sums due and to become
due thereon in respect of principal, premium and interest, but such money
need not be segregated from other funds except to the extent required by law.

          The Company shall pay and indemnify the Trustee against any tax,
fee or other charge imposed on or assessed against the U.S. Government
Obligations deposited pursuant to paragraph (d) above or the principal,
premium, if any, and interest received in respect thereof other than any such
tax, fee or other charge which by law is for the account of the Holders of
the outstanding Securities.

          Anything in this Section 8.02 to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon the
request, in writing, by the Company any money or U.S. Government Obligations
held by it as provided in paragraph (d) above which, in the opinion of a
nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee, are in excess of the
amount thereof which would then be required to be deposited to effect an
equivalent legal defeasance or covenant defeasance.

          8.03.   Application of Trust Money.

          The Trustee shall hold in trust money or U.S. Government
Obligations deposited with it pursuant to Sections 8.01 and 8.02, and shall
apply the deposited money and the money from U.S. Government Obligations in
accordance with this Indenture to the payment of principal of, premium, if
any, and interest on the Securities.
<PAGE>

          8.04.   Repayment to Company.

          Subject to Sections 7.08, 8.01 and 8.02, the Trustee shall promptly
pay to the Company, upon receipt by the Trustee of an Officers' Certificate,
any excess money, determined in accordance with Section 8.02, held by it at
any time.  The Trustee and the Paying Agent shall pay to the Company, upon
receipt by the Trustee or the Paying Agent, as the case may be, of an
Officers' Certificate, any money held by it for the payment of principal,
premium, if any, or interest that remains unclaimed for two years after
payment to the Holders is required; provided, however, that the Trustee and
the Paying Agent before being required to make any payment may, but need not,
at the expense of the Company cause to be published once in a newspaper of
general circulation in The City of New York or mail to each Holder entitled
to such money notice that such money remains unclaimed and that after a date
specified therein, which shall be at least 30 days from the date of such
publication or mailing, any unclaimed balance of such money then remaining
will be repaid to the Company.  After payment to the Company, Holders
entitled to money must look solely to the Company for payment as general
creditors unless an applicable abandoned property law designates another
person, and all liability of the Trustee or Paying Agent with respect to such
money shall thereupon cease.

          8.05.   Reinstatement.

          If the Trustee or Paying Agent is unable to apply any money or U.S.
Government Obligations in accordance with this Indenture by reason of any
legal proceeding or by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, then and only then the Company's obligations under this
Indenture and the Securities shall be revived and reinstated as though no
deposit had been made pursuant to this Indenture until such time as the
Trustee is permitted to apply all such money or U.S. Government Obligations
in accordance with this Indenture; provided, however, that if the Company has
made any payment of principal of, premium, if any, or interest on any
Securities because of the reinstatement of its obligations, the Company shall
be subrogated to the rights of the Holders of such Securities to receive such
payment from the money or U.S. Government Obligations held by the Trustee or
Paying Agent.

                                  ARTICLE NINE

                      AMENDMENTS, SUPPLEMENTS AND WAIVERS

          9.01.   Without Consent of Holders.

          The Company, when authorized by a Board Resolution of its Board of
Directors, and the Trustee may amend, waive or supplement this Indenture, the
Securities or any of the Pledge Agreements without notice to or the consent
of any Holder:
          (a)  to cure any ambiguity, defect or inconsistency;
          (b)  to comply with Article Five of this Indenture;
          (c)  to provide for uncertificated Securities in addition to
     certificated Securities;
          (d)  to comply with any requirements of the SEC in order to effect
     or maintain the qualification of this Indenture under the TIA;
          (e)  to make any change that would provide any additional benefit
     or rights to the Holders or that does not adversely affect the rights of
     any Holder.

          Notwithstanding the above, the Trustee and the Company may not make
any change that adversely affects the rights of any Holders hereunder.  The
Company shall be required to deliver to the Trustee an Opinion of Counsel
stating that any such change made pursuant to paragraph (a) or (e) of this
Section 9.01 does not adversely affect the rights of any Holder.

          9.02.   With Consent of Holders.

          Subject to Section 6.04, the Company, when authorized by a Board
Resolution and the Trustee may amend this Indenture, the Securities or any of
the Pledge Agreements with the written consent of the Holders of at least a
majority in aggregate principal amount of the Securities then outstanding,
and the Holders of at least a majority in aggregate principal amount of the
Securities then outstanding by written notice to the Trustee may waive future
compliance by the Company with any provision of this Indenture, the
Securities or any of the Pledge Agreements.
<PAGE>

          Notwithstanding the provisions of this Section 9.02, without the
consent of each Holder affected, an amendment or waiver, including a waiver
pursuant to Section 6.04, may not:
          (a)  reduce the principal amount of, extend the fixed maturity of,
     or alter the redemption provisions of, the Securities;
          (b)  change the currency in which any Security, or any premium or
     interest thereon, is payable or make the principal of, premium, if any,
     or interest on any Security payable in money other than that stated in
     the Security;
          (c)  reduce the percentage in principal amount of outstanding
     Securities the Holders of which must consent to an amendment or
     supplement to or waiver of any provision of or consent to take any
     action under this Indenture, the Securities or any of the Pledge
     Agreements;
          (d)  impair the right to institute suit for the enforcement of any
     payment on or with respect to the Securities;
          (e)  waive a default in the payment with respect to, the
     Securities; or
          (f)  reduce or change the rate or time for payment of interest on
     any Security.

          It shall not be necessary for the consent of the Holders under this
Section 9.02 to approve the particular form of any proposed amendment,
supplement or waiver, but it shall be sufficient if such consent approves the
substance thereof.

          After an amendment, supplement or waiver under this Section 9.02
becomes effective, the Company shall mail to the Holder of each Security
affected thereby, with a copy to the Trustee, a notice briefly describing the
amendment, supplement or waiver.  Any failure of the Company to mail such
notice, or any defect therein, shall not, however, in any way impair or
affect the validity of any amendment, supplement or waiver.

          9.03.   Compliance with Trust Indenture Act.

          Every amendment of or supplement to this Indenture or the
Securities shall comply with the TIA as then in effect.

          9.04.   Revocation and Effect of Consents.

          Until an amendment, supplement or waiver becomes effective, a
consent to it by a Holder is a continuing consent by such Holder and every
subsequent Holder of that Security or portion of that Security that evidences
the same debt as the consenting Holder's Security, even if notation of the
consent is not made on any Security.  However, any such Holder or subsequent
Holder may revoke the consent as to his Security or portion of a Security
prior to such amendment, supplement or waiver becoming effective.  Such
revocation shall be effective only if the Trustee receives the notice of
revocation before the date the amendment, supplement or waiver becomes
effective.  Notwithstanding the above, nothing in this paragraph shall impair
the right of any Holder under Section 316(b) of the TIA.

          The Company may, but shall not be obligated to, fix a record date
for the purpose of determining the Holders entitled to consent to any
amendment, supplement or waiver.  If a record date is fixed, then
notwithstanding the second and third sentences of the immediately preceding
paragraph, those persons who were Holders at such record date (or their duly
designated proxies), and only those persons, shall be entitled to consent to
such amendment, supplement or waiver or to revoke any consent previously
given, whether or not such persons continue to be Holders after such record
date.  Such consent shall be effective only for actions taken within 90 days
after such record date.

          After an amendment, supplement or waiver becomes effective, it
shall bind every Holder; unless it makes a change described in any of clauses
(a) through (f) of Section 9.02; if it makes such a change, the amendment,
supplement or waiver shall bind every subsequent Holder of a Security or
portion of a Security that evidences the same debt as the consenting Holder's
Security.
<PAGE>

          9.05.   Notation on or Exchange of Securities.

          If an amendment, supplement or waiver changes the terms of a
Security, the Trustee shall (in accordance with the specific direction of the
Company) request the Holder of the Security to deliver it to the Trustee.
The Trustee shall (in accordance with the specific direction of the Company)
place an appropriate notation on the Security about the changed terms and
return it to the Holder.  Alternatively, if the Company or the Trustee so
determines, the Company in exchange for the Security shall issue and the
Trustee shall authenticate a new Security that reflects the changed terms.
Failure to make the appropriate notation or issue a new Security shall not
affect the validity and effect of such amendment, supplement or waiver.

          9.06.   Trustee May Sign Amendments, etc.

          The Trustee shall sign any amendment, supplement or waiver
authorized pursuant to this Article Nine if the amendment, supplement or
waiver does not adversely affect the rights, duties, liabilities or
immunities of the Trustee.  If it does, the Trustee may, but need not, sign
it.  In signing or refusing to sign such amendment, supplement or waiver, the
Trustee shall be entitled to receive, and shall be fully protected in relying
upon, an Officers' Certificate and an Opinion of Counsel stating that the
execution of any amendment, supplement or waiver is authorized or permitted
by this Indenture, that it is not inconsistent herewith and that it will be
valid and binding upon the Company in accordance with its terms.

                                  ARTICLE TEN

                        PLEDGED COLLATERAL AND SECURITY

          10.01.  Pledge Agreements.

          The due and punctual payment of the principal of and interest on
the Securities when and as the same shall be due and payable, whether on an
interest payment date, at maturity, by acceleration, repurchase, redemption
or otherwise, and interest on the overdue principal of and interest (to the
extent permitted by law), if any, on the Securities and performance of all
other obligations of the Company to the Holders or the Trustee under this
Indenture and the Securities, according to the terms hereunder or thereunder,
shall be secured as provided in the Pledge Agreements, which the Company has
entered into simultaneously with the execution of this Indenture.  Each
Holder, by its acceptance of the Securities, consents and agrees to the terms
of the Pledge Agreements (including, without limitation, the provisions
providing for foreclosure and release of Pledged Collateral) as the same may
be in effect or may be amended from time to time in accordance with their
respective terms and authorizes and directs the Trustee to enter into the
Pledge Agreements and to perform its obligations and exercise its rights
thereunder in accordance therewith.  The Company shall deliver to the Trustee
a copy of the Pledge Agreements, and shall do or cause to be done all such
acts and things as may be necessary or proper, or as may be required by the
provisions of the Pledge Agreements, or as may be reasonably requested by the
Trustee, to assure and confirm to the Trustee the security interests in the
Pledged Collateral contemplated hereby or by the Pledge Agreements, as from
time to time constituted, so as to render the same available for the security
and benefit of this Indenture and of the Securities secured hereby, according
to the intent and purposes herein expressed.  The Company shall take, or
shall cause its subsidiaries to take, any and all actions reasonably required
to cause the Pledge Agreements to create and maintain, as security for the
obligations of the Company hereunder and under the Securities, valid and
enforceable perfected Liens in and on all the Pledged Collateral, in favor of
the Trustee for the benefit of the Holders, superior to and prior to the
rights of all third persons, except for those Liens expressly contemplated by
the Pledge Agreements.
<PAGE>

          10.02.  Recording and Opinions.

          (a)  The Company shall furnish to the Trustee simultaneously with
the execution and delivery of this Indenture one or more Opinions of Counsel
either (i) stating that in the opinion of such counsel all action has been
taken with respect to the recording, registering and filing of this
Indenture, financing statements or other instruments necessary to make
effective the Liens intended to be created by the Pledge Agreements, and
reciting with respect to the security interests in the Pledged Collateral,
the details of such actions, or (ii) stating that, in the opinion of such
counsel, no such action is necessary to make such Liens effective.

          (b)  The Company shall furnish to the Trustee simultaneously with
the execution and delivery of each additional Pledge Agreement, any Note
Pledge Agreement, any Security Agreement or any substitution of Collateral
under any such agreement, one or more Opinions of Counsel either (i) stating
that in the opinion of such counsel all action has been taken with respect to
the recording, registering and filing of any financing statements or other
instruments necessary to make effective the Liens intended to be created by
such agreement, and reciting with respect to the details in the new
Collateral (by way of substitution or otherwise) the details of such actions,
or (ii) stating that, in the opinion of such counsel, no such action is
necessary to make such Liens effective.

          (c)  The Company shall furnish to the Trustee on June 30 in each
year beginning with June 30, 1996, one or more Opinions of Counsel, each
dated as of such date, either (i) (A) stating that, in the opinion of such
counsel, all action has been taken with respect to the recording,
registering, filing, re-recording, re-registering and refiling of all
financing statements, continuation statements or other instruments of further
assurance as is necessary (1) to make effective the Liens intended to be
created by the Note Pledge Agreements and (2) to maintain the Liens of the
Pledge Agreements and any Note Pledge Agreements and Security Agreements and
reciting with respect to the security interests in the applicable Collateral
the details of such actions or referring to prior Opinions of Counsel in
which such details are given and (B) based on relevant laws as in effect on
the date of each such Opinion of Counsel, all financing statements and
continuation statements have been executed and filed that are necessary as of
such date and during the succeeding 12 months fully to preserve and protect,
to the extent such protection and preservation are possible by filing, the
rights of the Holders and the Trustee hereunder and under the Pledge
Agreements and any Note Pledge Agreements and Security Agreements with
respect to the security interests in the Collateral, or (ii) stating that, in
the opinion of such counsel, no such action is necessary to make effective
and/or maintain such Liens, as the case may be.

          10.03.  Release of Collateral.

          (a)  Subject to subsections (b), (c) and (d) of this Section 10.03,
Collateral may be released from the Liens and security interests created by
the Pledge Agreements and any Note Pledge Agreements and Security Agreements
at any time or from time to time in accordance with the provisions of such
agreements and as provided hereby.  In addition, upon the request of the
Company pursuant to an Officers' Certificate certifying that all conditions
precedent hereunder and under any such agreements, to the extent applicable,
have been met and stating whether or not such release is in connection with
an Asset Sale or a Collateral Release Request, the Trustee shall (at the sole
cost and expense of the Company) release Collateral which is sold, conveyed
or disposed of in compliance with the provisions of this Indenture and any
such agreements, to the extent applicable, provided, that if such sale,
conveyance or disposition constitutes an Asset Sale, the Company shall apply
the Net Cash Proceeds in accordance with Section 4.12 and any such
agreements, to the extent applicable.  Upon receipt of such Officers'
Certificate, the Trustee shall execute, deliver or acknowledge any necessary
or proper instruments of termination, satisfaction or release to evidence the
release of any Collateral permitted to be released pursuant to this Indenture
and any such agreements, to the extent applicable.
<PAGE>

          (b)  Except to the extent that any Lien on the proceeds of
Collateral is automatically released by operation of Section 9-306 of the
Uniform Commercial Code or other similar law, no Collateral shall be released
from the Liens and security interests created by the Pledge Agreements and
any Note Pledge Agreements and/or Security Agreements pursuant to the
provisions of such agreements unless there shall have been delivered to the
Trustee the certificate required by this Section 10.03.

          (c)  At any time when an Event of Default shall have occurred and
be continuing and the maturity of the Securities shall have been accelerated
(whether by declaration or otherwise), no Collateral shall be released
pursuant to the provisions of the Pledge Agreements and any Note Pledge
Agreements and/or Security Agreements, and no release of Collateral in
contravention of this Section 10.03(c) shall be effective as against the
Holders.

          (d) The release of any Collateral from the Liens and security
interests created by this Indenture and the Pledge Agreements and any Note
Pledge Agreements and/or Security Agreements shall not be deemed to impair the
security under this Indenture in contravention of the provisions hereof if and
to the extent that any such Collateral is released pursuant to the terms hereof
or, subject to complying with the requirements of this Section 10.03, pursuant
to the terms of the Pledge Agreements and any Note Pledge Agreements and/or
Security Agreements. To the extent applicable, the Company shall cause TIA
Section 314(d) relating to the release of property or securities from the Liens
and security interests of the Pledge Agreements and any Note Pledge Agreements
and relating to the substitution therefor of any property or securities to be
subjected to the Liens and security interests of the Pledge Agreements and any
Note Pledge Agreements to be complied with. Any certificate or opinion required
by TIA Section 314(d) may be made by an Officer of the Company except in cases
where TIA Section 314(d) requires that such certificate or opinion be made by an
independent person, which person shall be an independent engineer, appraiser or
other expert selected or approved by the Trustee in the exercise of reasonable
care.

          10.04.  Certificates of the Company.

          (a)  The Company shall furnish to the Trustee, prior to each
proposed release of Collateral pursuant to the Pledge Agreements and any Note
Pledge Agreements, (i) all documents required by Section 314(d) of the TIA
and (ii) an Opinion of Counsel, which may be rendered by internal counsel to
the Company, to the effect that such accompanying documents constitute all
documents required by Section 314(d) of the TIA.  The Trustee may, to the
extent permitted by Sections 7.01 and 7.02 hereof, accept as conclusive
evidence of compliance with the foregoing provisions the appropriate
statements contained in such documents and such Opinion of Counsel.

          10.05.  Authorization of Actions to Be Taken by
                  the Trustee Under the Security Documents.

          Subject to the provisions of Sections 7.01 and 7.02 hereof, the
Trustee may, in its sole discretion and without the consent of the Holders,
on behalf of the Holders, take all actions it deems necessary or appropriate
in order to (a) enforce any of the terms of the Pledge Agreements and any
Note Pledge Agreements and/or Security Agreements and (b) collect and receive
any and all amounts payable in respect of the obligations of the Company
hereunder.  The Trustee shall have power to institute and maintain such suits
and proceedings as it may deem expedient to prevent any impairment of the
Collateral by any acts that may be unlawful or in violation of the Pledge
Agreements and any Note Pledge Agreements and/or Security Agreements or this
Indenture, and such suits and proceedings as the Trustee may deem expedient
to preserve or protect its interests and the interests of the Holders in the
Collateral (including power to institute and maintain suits or proceedings to
restrain the enforcement of or compliance with any legislative or other
governmental enactment, rule or order that may be unconstitutional or
otherwise invalid if the enforcement of, or compliance with, such enactment,
rule or order would impair the security interest hereunder or be prejudicial
to the interests of the Holders or of the Trustee).
<PAGE>

          10.06.  Authorization of Receipt of Funds by the
                  Trustee Under the Security Documents.     

          The Trustee is authorized to receive any funds for the benefit of
the Holders distributed under the Pledge Agreements and any Note Pledge
Agreements and/or Security Agreements, and to make further distributions of
such funds to the Holders according to the provisions of this Indenture.

          10.07.  Termination of Security Interests.

          Upon the payment in full of all obligations of the Company under
this Indenture, the Securities, the Pledge Agreements and any Note Pledge
Agreements and/or Security Agreements, the Trustee shall, at the request of
the Company and upon receipt of an Officers' Certificate certifying as to the
foregoing, release the Liens pursuant to this Indenture and the Pledge
Agreements and any Note Pledge Agreements and/or Security Agreements.

          10.08.  Releases Following Sale of Assets.

          Concurrently with any sale of assets, any Liens in favor of the
Trustee in the assets sold thereby shall be released; provided, that in the
event of an Asset Sale, the Net Cash Proceeds from such sale or other
disposition are applied in accordance with the provisions of Section 4.12,
the Pledge Agreements and any Note Pledge Agreements and/or Security
Agreements; provided, further, that, the Net Cash Proceeds resulting from any
sale or disposition of Collateral are applied to the purchase of Replacement
Assets that are subject to a first priority perfected Lien in favor of the
Trustee or the acquisition or formation of a Subsidiary that, when acquired
or formed, will have all of its outstanding Capital Stock subject to a first
priority perfected Lien in favor of the Trustee.  If the Company does not
apply such Net Cash Proceeds in accordance with the preceding sentence, such
Net Cash Proceeds shall remain in an account subject to a first priority
perfected Lien in favor of the Trustee and shall not be released until the
obligations of the Company under this Indenture and the Securities, have been
discharged, the Pledge Agreements, and any Securities Pledge Agreements
and/or Security Agreements shall have otherwise been terminated or until such
Net Cash Proceeds have been distributed to the Holders of the Securities as
Excess Proceeds.

          10.09.  "Trustee" to Include Paying Agent.

          In case at any time a Paying Agent other than the Trustee shall
have been appointed by the Company and be then acting hereunder, the term
"Trustee" as used in this Article Ten shall in such case (unless the context
shall otherwise require) be construed as extending to and including such
Paying Agent within its meaning as fully and for all intents and purposes as
if such Paying Agent were named in this Article Ten.

          10.10.  Nominees of the Trustee.

          Notwithstanding anything contained herein to the contrary, the
Trustee may in its sole discretion designate a nominee or nominees to hold
any Collateral on its behalf and/or to exercise on its behalf any voting or
other rights or powers with respect thereto, provided, however, that nothing
contained in this Section 10.10 shall relieve the Trustee from any of its
obligations hereunder.

          10.11.  Pledge of Notes Pertaining to Certain
                  Intercompany Indebtedness.           

          The Company shall not, on or at any time after the date of this
Indenture, make any cash investment in any wholly-owned subsidiary of the
Company which is organized under the laws of the United States or any state
thereof or the District of Columbia and which is doing business in the United
States (each, a "Subsidiary Borrower") unless such investment is structured
as a loan by the Company to such Subsidiary Borrower (an "Intercompany
Loan").  The Company shall cause each such Intercompany Loan to be evidenced
by a promissory note (an "Intercompany Note") executed by the Subsidiary
Borrower in favor of the Company, which such Intercompany Loan shall be on
commercially reasonable terms, and which such Intercompany Note shall be in
form and substance typical for loans of such type and satisfactory to the
Trustee, and the Company, by means of one or more pledge agreements (each, a
"Note Pledge Agreement") substantially similar in form and substance to the
U.S. Pledge Agreement, with only such reasonable modifications as shall be
necessary to reflect differences in the type of Collateral being pledged,
shall pledge such Intercompany Notes as Collateral in favor of the Trustee
for the benefit of the Holders.  The Company shall deliver to the Trustee a
<PAGE>

copy of each Note Pledge Agreement prior to the making of any such
Intercompany Loan, and shall, prior to the making of any such Intercompany
Loan, do or cause to be done all such acts and things as may be necessary or
proper, or as may be required by the provisions of the Note Pledge
Agreements, or as may be reasonably requested by the Trustee, to assure and
confirm to the Trustee the security interests contemplated thereby, which
such security interests shall be first priority liens, so as to render the
same available for the security and benefit of this Indenture and of the
Securities secured hereby, according to the intent and purposes herein
expressed.  The Company shall take, and shall cause each Subsidiary Borrower
to take, any and all action reasonably required or requested by the Trustee
to cause the Note Pledge Agreements to create and maintain valid and
enforceable perfected Liens in and on all the Collateral pledged thereby, in
favor of the Trustee for the benefit of the Holders, superior to and prior to
the rights of all third persons.

          10.12.  Collateral Release Request.

          (a)  At any time during which no Default or Event of Default or
event which with notice or lapse of time or both would become a Default or an
Event of Default shall have occurred or be continuing, and upon receipt by
the Trustee of an Officers' Certificate certifying as to the foregoing, the
Company may request (each such request being a "Collateral Release Request"
and the date such request is made being the "Collateral Release Request
Date") in writing the Holders' consent to terminate the Collateral
Arrangements and release the Collateral as provided hereby.

          (b)  A Collateral Release Request shall be mailed by the Company to

           (iv)   that if, upon the conclusion of such 30 Business Day period
     commencing on the Collateral Release Request Date, Holders of 66 2/3% or
     more of the aggregate principal amount at maturity of the Securities
     outstanding on the Collateral Release Request Date consent thereto, the
     Collateral Arrangements (including, without limitation, the Guarantees)
     shall terminate and the Collateral shall be released upon delivery to
     the Trustee of an Officers' Certificate setting forth the votes received
     on the Collateral Release Request; and
            (v)   that if, upon the conclusion of such 30 Business Day period
     commencing on the Collateral Release Request Date, Holders of less than

     interest, if any, to the date of purchase (the "Collateral Release
     Purchase Date") and, if a Collateral Release Offer is made, the Company,
     within 40 Business Days after the Collateral Release Offer, shall

     accrued and unpaid interest, if any, to the date of purchase (the
     "Collateral Release Purchase Date") and upon the consummation of such
     purchase, the Collateral Arrangements shall terminate and the Collateral
     shall be released.

Company not less than 20 nor more than 40 Business Days before the Collateral
Release Purchase Date to all Holders at their last registered address with a

     date on which the Collateral Release Offer expires;
          (iii)   that any Security not tendered or accepted for payment will

Request Date, and the Paying Agent shall promptly mail or deliver such amount
to such voting Holders on a pro rata basis.

          GEOTEK COMMUNICATIONS, INC., a corporation incorporated under the
laws of the State of Delaware (herein called the "Company", which term
includes any successor corporation under the Indenture hereinafter referred
to), for value received, hereby promises to pay to CEDE & CO. or registered
assigns, the principal sum of Two Hundred Seven Million Dollars on July 15,
2005, at the office or agency of the Company referred to below, and to pay
cash interest thereon, which such interest will accrue from and after
July 15, 2000 at the rate of 15% per annum (subject to adjustment, as
provided on the reverse hereof) and will be payable on January 15 and
July 15, in each year, commencing on January 15, 2001, accruing from the most
recent Interest Payment Date to which interest has been paid or duly provided
for or, if no interest has been paid, from July 15, 2000, until the principal
hereof is paid or duly provided for.  Interest shall be computed on the basis
of a 360-day year of twelve 30-day months from July 6, 1995.  No interest
shall be payable on the Securities prior to July 15, 2000.
          The interest so payable, and punctually paid or duly provided for,
on any Interest Payment Date will, as provided in the Indenture referred to
on the reverse hereof, be paid to the person in whose name this Security is
registered at the close of business on the regular record date for such
interest, which shall be January 1 or July 1 (whether or not a Business Day),
as the case may be, next preceding such Interest Payment Date and may be
paid, at the option of the Company, by check mailed to such person.  Any such
interest not so punctually paid, or duly provided for, and interest on such
defaulted interest at the rate borne by the Securities, to the extent lawful,
shall forthwith cease to be payable to the Holder on such regular record
date, and may be paid to the person in whose name this Security (or one or
more Predecessor Securities) is registered at the close of business on a
special record date for the payment of such defaulted interest to be fixed by
the Trustee, notice of which shall be given to Holders of Securities not less
than 10 days prior to such special record date, or may be paid at any time in
any other lawful manner not inconsistent with the requirements of any
securities exchange on which the Securities may be listed, and upon such
notice as may be required by such exchange, all as more fully provided in
such Indenture.
          This Security is issued with original issue discount for Federal
income tax purposes in the aggregate amount of $136,187,370 ($657.91 per

reference is hereby made for a statement of the respective rights,
limitations of rights, duties, obligations and immunities thereunder of the
Company, the Trustee and the Holders of the Securities, and of the terms upon
which the Securities are, and are to be, authenticated and delivered.

          All capitalized terms used in this Security which are defined in
the Indenture and not otherwise defined herein shall have the meanings
assigned to them in the Indenture.

          No reference herein to the Indenture and no provisions of this

          2.   Additional Interest.

following the Issue Date, then, commencing on the 61st day after the Issue
Date, additional interest payable in cash (the "Additional Interest") shall
accrue on the Series A Notes at a rate of 0.50% per annum for the first 90
days immediately following the 60th day after the Issue Date, such Additional
Interest rate increasing by an additional 0.25% per annum at the beginning of
each subsequent 90-day period;
 
         (b)  if a Registration Statement is filed pursuant to clause (a)
above or otherwise prior to 120 days following the Issue Date and is not
declared effective within such 120-day period, then, commencing on the 121st
day after the Issue Date, Additional Interest shall accrue on the Series A
Notes at a rate of 0.50% per annum for the first 90 days immediately
following the 120th day after the Issue Date, such Additional Interest rate
increasing by an additional 0.25% per annum at the beginning of each
subsequent 90-day period; and

          (c)  if (i) the Company has not exchanged Series B Notes for all
Series A Notes validly tendered in accordance with the terms of the Exchange
Offer on or prior to 45 days after the date on which the Registration
Statement was declared effective or (ii) if applicable, the Shelf
Registration Statement ceases to be effective or the prospectus which is a
part thereof cannot be used as a result of a Suspension Event Notice for a
period of more than 90 days, in each case under this clause (ii) prior to
three years from the effective date of such Shelf Registration Statement,
then Additional Interest shall accrue on the Series A Notes at a rate of
0.50% per annum for the first 60 days immediately following (A) the 46th day

Series A Notes validly tendered or upon the effectiveness of the Shelf
Registration Statement that had ceased to remain effective prior to three

more Predecessor Securities, of record at the close of business on the
relevant Record Date referred to on the face hereof.  Securities (or portions
thereof) for whose redemption and payment provision is made in accordance
with the Indenture shall cease to bear interest from and after the Redemption
Date.

          (d)  Partial Redemption.  In the event of redemption of this
Security in part only, a new Security or Securities for the unredeemed
portion hereof shall be issued in the name of the Holder hereof upon the

          4.   Offers to Purchase.  Sections 4.11, 4.12 and 10.12 of the
Indenture, respectively, provide that upon the occurrence of a Change of
Control, following certain Asset Sales and in connection with a Collateral
Release Request, and subject to further limitations contained therein, the
Company shall make an offer to purchase certain amounts of the Securities in
accordance with the procedures set forth in the Indenture.

          5.   Defaults and Remedies.  If an Event of Default shall occur and
be continuing, the principal of premium, if any, all of the outstanding
Securities, plus all accrued and unpaid interest, if any, to and including
the date the Securities are paid, may be declared due and payable immediately
in the manner and with the effect provided in the Indenture.

          6.   Defeasance.  The Indenture contains provisions (which
provisions apply to this Security) for defeasance at any time of (a) the
entire indebtedness of the Company under this Security and (b) certain
restrictive covenants and related Defaults and Events of Default, in each
case upon compliance by the Company with certain conditions set forth
therein.

          7.   Amendments and Waivers.  The Indenture and the Pledge

the rights and obligations of the Company and the rights of the Holders under
the Indenture and the Pledge Agreements at any time by the Company and the
Trustee with the consent of the Holders of at least a majority in aggregate
principal amount of the Securities at the time outstanding.  The Indenture

aggregate principal amount of the Securities at the time outstanding, on
behalf of the Holders of all the Securities, to waive compliance by the
Company with certain provisions of the Indenture and the Pledge Agreements
and certain past Defaults under the Indenture and this Security and their
consequences.  Any such consent or waiver by or on behalf of the Holder of
this Security shall be conclusive and binding upon such Holder and upon all
future Holders of this Security and of any Security issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof
whether or not notation of such consent or waiver is made upon this Security.

          8.   Denominations, Transfer and Exchange.  The Securities are
issuable only in registered form without coupons in denominations of $1,000
principal amount at maturity and any integral multiple thereof.  A Holder may
register the transfer or exchange of Securities in accordance with the
Indenture.  No service charge shall be made for any registration of transfer
or exchange or redemption of Securities, but the Company may require payment
of a sum sufficient to cover any tax or other governmental charge payable in
connection therewith.

          9.   Persons Deemed Owners.  Prior to and at the time of due
presentment of this Security for registration of transfer, the Company, the
Trustee and any agent of the Company or the Trustee may treat the person in
whose name this Security is registered as the owner hereof for all purposes,
whether or not this Security shall be overdue, and neither the Company, the
Trustee nor any agent thereof shall be affected by notice to the contrary.

          10.  Security.  The Securities are secured by pledges of shares of
Capital Stock owned by the Company to the extent provided for in the
Indenture and the Pledge Agreements.

          11.  Guarantees.  Payment of the Accreted Value, premium (if any)
and interest (including interest on overdue principal and overdue interest,
if lawful) will, to the extent provided for in the Indenture, be
unconditionally guaranteed by certain subsidiaries of the Company.

          12.  Governing Law.  This Security shall be governed by and
construed in accordance with the laws of the State of New York, without
regard to conflicts of law principles.

provided on the reverse hereof) and will be payable on January 15 and
July 15, in each year, commencing on January 15, 2001, accruing from the most
recent Interest Payment Date to which interest has been paid or duly provided

hereof is paid or duly provided for.  Interest shall be computed on the basis
of a 360-day year of twelve 30-day months from July 6, 1995.  No interest
shall be payable on the Securities prior to July 15, 2000.

          The interest so payable, and punctually paid or duly provided for,

any other lawful manner not inconsistent with the requirements of any
securities exchange on which the Securities may be listed, and upon such
notice as may be required by such exchange, all as more fully provided in
such Indenture.

          Payment of the principal of, premium, if any, and interest on this
Security will be made at the office or agency of the Company maintained for
that purpose in the Borough of Manhattan in The City of New York, or at such

payment is legal tender for payment of public and private debts; provided,
however, that payment of interest may be made at the option of the Company by
check mailed to the address of the person entitled thereto as such address
shall appear on the security register maintained by the Registrar.

          Reference is hereby made to the further provisions of this Security
set forth on the reverse hereof.

executed by the Trustee referred to on the reverse hereof by manual
signature, and a seal has been affixed hereon, this Security shall not be

          (a)  To the extent not prohibited by any applicable law or
applicable interpretation of the staff of the SEC, the Company shall file
after the Closing Date and no later than September 4, 1995, an Exchange Offer
Registration Statement covering the offer by the Company to the Holders to
exchange all of the Registrable Notes for Exchange Notes and shall use its
best efforts to cause such Exchange Offer Registration Statement to be
declared effective by the SEC not later than November 3, 1995.  The Company
shall use its best efforts to cause such Registration Statement to remain
effective until the closing of the Exchange Offer.  The Company shall
commence the Exchange Offer promptly after the Exchange Offer Registration
Statement has been declared effective by the SEC and shall use its best
efforts to have the Exchange Offer consummated not later than the date that
is 45 days after the Exchange Offer Registration Statement is declared
effective.  The Company shall commence the Exchange Offer by mailing an
exchange offer Prospectus and accompanying documents to each Holder stating,
in addition to such other disclosures as are required by applicable law:

            (i)   that the Exchange Offer is being made pursuant to this
     Agreement and that all Registrable Notes that are eligible to be
     exchanged in the Exchange Offer under applicable law and applicable
     interpretations of the Staff of the SEC and are validly tendered will be
     accepted for exchange;

           (ii)   the dates of acceptance for exchange (which shall be each
     business day during a period of at least 30 days from the date such
     notice is mailed) (the "Exchange Dates");

          (iii)   that any Registrable Note not tendered will remain
     outstanding and continue to accrete and accrue interest, but will not
     retain any rights under this Agreement;

           (iv)   that Holders electing to have a Registrable Note exchanged
     pursuant to the Exchange Offer will be required to surrender such
     Registrable Note, together with the enclosed letters of transmittal, to
     the institution and at the address (located in the Borough of Manhattan,
     City of New York) specified in the notice prior to the close of business
     on the last Exchange Date; and

            (v)   that Holders will be entitled to withdraw their election,
     not later than the close of business on the last Exchange Date, by
     sending to the institution and at the address (located in the Borough of
     Manhattan, City of New York) specified in the notice, a telegram, telex,
     facsimile transmission or letter setting forth the name of such Holder,
     the principal amount of Registrable Notes delivered for exchange and a
     statement that such Holder is withdrawing his election to have such
     Notes exchanged.

          As soon as practicable after the last Exchange Date, the Company or
its agent shall:

            (i)   accept for exchange Registrable Notes or portions thereof
     tendered and not validly withdrawn pursuant to the Exchange Offer; and

           (ii)   deliver, or cause to be delivered, to the Trustee for
     cancellation all Registrable Notes or portions thereof so accepted for
     exchange by the Company and issue, and cause the Trustee to promptly
     authenticate and mail to each Holder, an Exchange Note equal in
     principal amount at maturity to the principal amount at maturity of the
     Registrable Notes surrendered by such Holder.

          The Company shall use its best efforts to complete the Exchange
Offer as provided above and shall comply with the applicable requirements of
the Securities Act, the Exchange Act and other applicable laws and
regulations in connection with the Exchange Offer.  The Exchange Offer shall
not be subject to any conditions, other than that the Exchange Offer does not
violate applicable law or any applicable interpretation of the staff of the
SEC and that no order of any governmental agency or court of competent
jurisdiction would be violated by consummating the Exchange Offer.


<PAGE>

          (b)  In the event that (i) any changes in law or the applicable
interpretations of the staff of the SEC do not permit the Company to effect
the Exchange Offer or the Exchange Offer is otherwise prohibited or (ii) the
Initial Purchaser holds any portion of the Notes purchased by it under the
Purchase Agreement, the Company shall use all reasonable best efforts to
cause to be filed no later than September 4, 1995 a Shelf Registration
Statement providing for the sale of the Registrable Notes and to have such
Shelf Registration Statement declared effective by the SEC no later than
November 3, 1995.  In the event that the Company is required to file a Shelf
Registration Statement solely as a result of the matters referred to in
clause (ii) of the preceding sentence, the Company shall file and use its
best efforts to have declared effective by the SEC both an Exchange Offer
Registration Statement pursuant to Section 2(a) with respect to all
Registrable Notes held by Holders other than the Initial Purchaser and a
Shelf Registration Statement (which may be a combined Registration Statement
with the Exchange Offer Registration Statement to the extent permitted by
applicable law) with respect to offers and sales of Registrable Notes held by
the Initial Purchaser.  The Company agrees to use all reasonable best efforts
to keep the Shelf Registration Statement continuously effective until the
third anniversary of the effective date thereof.  The Company further agrees
to supplement or amend the Shelf Registration Statement, if required by the
rules, regulations or instructions applicable to the registration form used
by the Company for such Shelf Registration Statement or by the Securities Act
or by any other rules and regulations thereunder for shelf registration or if
reasonably requested by a Holder with respect to information relating to such
Holder in order to accurately reflect information regarding such Holder or
such Holder's plan of distribution as required by the Shelf Registration
Statement, and to use its best efforts to cause any such amendment to become
effective and such Shelf Registration Statement to become usable as soon as
thereafter practicable.  The Company agrees to furnish to the Holders of
Registrable Notes copies of any such supplement or amendment promptly after
its being made available for use or filed with the SEC.

          (c)(i)  The Holders of Registrable Notes covered by a Shelf
Registration Statement who desire to do so may sell such Registrable Notes in
an Underwritten Offering subject to the limitations set forth in the proviso
to the first sentence of Section 3(q) hereunder (including the Company's
obligation to use its best efforts in connection therewith).  In any such
Underwritten Offering, the investment banker or investment bankers and
manager or managers (the "Underwriters") that will administer the offering
will be selected by the Majority Holders of the Registrable Notes included in
such offering.

          (ii)  Each Holder whose Registrable Notes are covered by a Shelf
Registration Statement filed pursuant to Section 2(b) agrees, upon the
request of the Underwriter(s) in any Underwritten Offering permitted pursuant
to this Agreement, not to effect any public sale or distribution of
securities of the Company of the same class as the Registrable Notes included
in such Shelf Registration Statement (except as part of such registration),
including a sale pursuant to Rule 144 under the Securities Act, during the
10-day period prior to, and during the 90-day period beginning on, the
closing date of any such Underwritten Offering made pursuant to such Shelf
Registration Statement, to the extent timely notified in writing by the
Company or such Underwriter(s).

          The foregoing provision shall not apply to any Holder if such
Holder is prevented by applicable statute or regulation from entering into
any such agreement; provided, however, that any such Holder shall undertake,
in its request to participate in any such Underwritten Offering, not to
effect any public sale or distribution of any of its Registrable Notes not
sold in such Underwritten Offering, commencing on the date of sale of such
Registrable Notes unless it has provided 45 days' prior written notice of
such sale or distribution to the Underwriter(s).


<PAGE>

          (iii)  The Company agrees not to effect any public or private
offer, sale or distribution of securities of the same quality and nature as
the Registrable Notes, including a sale pursuant to Regulation D under the
Act, during the 10-day period prior to, and during the 90-day period
beginning on, the closing date of each Underwritten Offering permitted
pursuant to Section 3(q) hereof made pursuant to the Shelf Registration
Statement, to the extent timely notified in writing by the Underwriter(s).

          (d)  The Company shall pay all Registration Expenses in connection
with any registration pursuant to Section 2(a) or 2(b).  Each Holder shall
pay all underwriting discounts and commissions and transfer taxes, if any,
relating to the sale or disposition of such Holder's Registrable Notes
pursuant to the Shelf Registration Statement.

          (e)  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 a Shelf Registration
Statement has been declared effective, the offering of Registrable Notes
pursuant thereto is interfered with by any stop order, injunction or other
order or requirement of the SEC or any other governmental agency or court,
such Shelf Registration Statement will be deemed not to have been effective
during the period of such interference until the offering of Registrable
Notes pursuant to such Registration Statement may legally resume.

          (f)  Upon the occurrence or failure to occur of certain events
described in the Notes, additional interest will accrue on the Notes, as
provided for in the Notes.

          (g)  Without limiting the remedies available to the Initial
Purchaser and subsequent Holders, the Company acknowledges that any failure
by the Company to comply with its obligations under Section 2(a) and/or
Section 2(b) hereof may result in material irreparable injury to the Initial
Purchaser and/or subsequent 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 subsequent 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.

          3.  Registration Procedures.  In connection with the obligations of
the Company with respect to the Registration Statements pursuant to Sections
2(a) and 2(b) hereof, the Company shall, as expeditiously as possible:

          (a)  prepare and file with the SEC a Registration Statement on the
     appropriate form under the Securities Act, which form shall, (x) be
     selected by the Company, (y) in the case of a Shelf Registration, be
     available for the sale of the Registrable Notes by the selling Holders
     thereof and (z) comply as to form in all material respects with the
     requirements of the applicable form and include all financial statements
     required by the SEC to be filed therewith, and use all reasonable best
     efforts to cause such Registration Statement to become effective and
     remain effective in accordance with Section 2 hereof;

          (b)  prepare and file with the SEC such amendments and post-
     effective amendments to each Registration Statement as may be necessary
     to (x) keep such Registration Statement effective for the applicable
     period under this Agreement and (y) cause each Prospectus to be
     supplemented by any required prospectus supplement and, as so
     supplemented, to be filed pursuant to Rule 424 under the Securities Act
     and (z) keep each Prospectus current during the period described under
     Section 4(3) and Rule 174 under the Securities Act that is applicable to
     transactions by brokers or dealers with respect to the Registrable Notes
     or Exchange Notes;


<PAGE>

          (c)  in the case of a Shelf Registration, furnish to each Holder of
     Registrable Notes, to counsel for the Initial Purchaser, to counsel for
     the Holders and to each Underwriter of an Underwritten Offering of
     Registrable Notes, if any, and each such Underwriter's Counsel, without
     charge, as many copies of each Prospectus, including each preliminary
     Prospectus, and any amendment or supplement thereto and such other
     documents as such Holder or Underwriter may reasonably request, in order
     to facilitate the public sale or other disposition of the Registrable
     Notes; the Company consents to the use of such Prospectus and any
     amendment or supplement thereto in accordance with applicable law by
     each of the selling Holders of Registrable Notes and any such
     Underwriters in connection with the offering and sale of the Registrable
     Notes covered by and in the manner described in such Prospectus or any
     amendment or supplement thereto in accordance with applicable law;

          (d)  use its reasonable best efforts to register or qualify the
     Registrable Notes or Exchange Notes under all applicable state
     securities or "blue sky" laws of such jurisdictions as any Holder of
     Registrable Notes or Exchange Notes covered by a Registration Statement
     shall reasonably request in writing by the time the applicable
     Registration Statement is declared effective by the SEC, to cooperate
     with such Holders in connection with any filings required to be made
     with the National Association of Securities Dealers, Inc. 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 Notes owned or Exchange Notes to be
     owned by such Holder; provided, however, that the Company shall not be
     required to (i) qualify as a foreign entity or as a dealer in securities
     in any jurisdiction where it would not otherwise be required to qualify
     but for this Section 3(d), (ii) file any general consent to service of
     process or (iii) subject itself to taxation in any such jurisdiction if
     it is not so subject;

          (e)  in the case of a Shelf Registration, notify each Holder of
     Registrable Notes, counsel for the Holders and counsel for the Initial
     Purchaser promptly and, if requested by any such Holder, confirm such
     advice in writing, (i) when a Shelf Registration Statement has become
     effective and when any post-effective amendments and supplements thereto
     have been filed and become effective, (ii) of any request by the SEC or
     any state securities authority for amendments and supplements to a Shelf
     Registration Statement and Prospectus or for additional information
     after the Shelf 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 Shelf Registration Statement or
     the initiation of any proceedings for that purpose, (iv) if, between the
     effective date of a Shelf Registration Statement and the closing of any
     sale of Registrable Notes 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
     or if the Company receives any notification with respect to the
     suspension of the qualification of the Registrable Notes for sale in any
     jurisdiction or the initiation of any proceeding for such purpose, (v)
     of the happening of any event which makes any statement made in a Shelf
     Registration Statement or the related Prospectus untrue in any material
     respect or which requires the making of any changes in a Shelf
     Registration Statement or Prospectus in order to make the statements
     therein not misleading and (vi) of any determination by the Company that
     a post-effective amendment to a Shelf Registration Statement would be
     appropriate;


<PAGE>

          (f)  make every reasonable effort to obtain the withdrawal of any
     order suspending the effectiveness of a Shelf Registration Statement at
     the earliest possible moment and provide prompt notice to each Holder of
     the withdrawal of any such order;

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

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

          (i)  in the case of a Shelf Registration, upon the occurrence of
     any event contemplated by Section 3(e)(v) hereof, use its reasonable
     best efforts to prepare a supplement or post-effective amendment to a
     Shelf 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
     Notes, such Prospectus will not contain 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 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;

          (j)  within a reasonable time prior to the filing of any Shelf
     Registration Statement, Prospectus to be included therein, or amendment
     or supplement therein, provide copies of such document to the Initial
     Purchaser and its counsel, and the Holders and their counsel, and make
     such of the representatives of the Company as shall be reasonably
     requested by the Initial Purchaser or its counsel, and the Holders or
     their counsel, available for discussion of such document, and shall not
     at any time file or make any amendment or supplement to any such
     document of which the Initial Purchaser and its counsel, and the Holders
     and their counsel, shall not have previously been advised and furnished
     a copy or in a form to which the Initial Purchaser or its counsel, and
     the Majority Holders or their counsel, shall reasonably object;
     provided, however, that any document incorporated by reference in any
     such Prospectus by any amendment or supplement shall be provided to the
     Initial Purchaser and its counsel and to the Holders and their counsel
     at the time that such amendment or supplement is filed with the SEC;

          (k)  obtain a CUSIP number for all Exchange Notes or Registrable
     Notes, as the case may be, not later than the effective date of a
     Registration Statement;

          (l)  cause the Indenture to be qualified under the Trust Indenture
     Act of 1939 (the "TIA") in connection with the registration of the
     Exchange Notes or Registrable Notes, as the case may be, 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 execute, and use its reasonable 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;


<PAGE>

          (m)  in the case of a Shelf Registration, make available for
     inspection by a representative of all of the Holders of the Registrable
     Notes, any Underwriter participating in any disposition pursuant to such
     Shelf Registration Statement and attorneys and accountants designated by
     the Holders or any Underwriter, at reasonable times and in a reasonable
     manner, all financial and other records, pertinent documents and
     properties of the Company, and cause the respective officers, directors
     and employees of the Company to supply all information reasonably
     requested by any such representatives, Underwriter, attorney or
     accountant in connection with a Shelf Registration Statement; provided,
     however, that such Underwriters, representatives, attorneys or
     accountants agree to keep confidential any records, information or
     documents that are designated by the Company in writing as confidential
     and to use such information obtained pursuant to this provision only in
     connection with the transaction for which such information was obtained,
     and not for any other purpose, unless (i) such records, information or
     documents (x) are available to the public, (y) were already in such
     Underwriters', representatives', attorneys' or accountants' possession
     prior to its receipt from the Company and they do not otherwise have any
     obligation to keep such records, information or documents confidential
     or (z) are obtained by such Underwriters, representatives, attorneys or
     accountants from a third person who, insofar as is known to such
     Underwriters, representatives, attorneys or accountants, is not
     prohibited from transmitting the information to such Underwriters,
     representatives, attorneys or accountants by a contractual, legal or
     fiduciary obligation to the Company or a third party, or (ii) disclosure
     of such records, information or documents is required by court or
     administrative order after the exhaustion of appeals therefrom;

          (n)  in the case of a Shelf Registration, use its reasonable best
     efforts to cause all Registrable Notes to be listed on any securities
     exchange or any automated quotation system on which similar securities
     issued by the Company are then listed if requested by the Majority
     Holders, to the extent such Registrable Notes satisfy applicable listing
     requirements;

          (o)  use its reasonable best efforts to cause the Exchange Notes or
     Registrable Notes, as the case may be, to continue to be rated by two
     nationally recognized statistical rating organizations (as such term is
     defined in Rule 436(g)(2) under the Securities Act);

          (p)  if reasonably requested by any Holder of Registrable Notes
     covered by a Registration Statement in order to accurately reflect
     information regarding such Holder or such Holder's plan of distribution
     as required by such Registration Statement, (i) promptly incorporate in
     a Prospectus supplement or post-effective amendment such information
     with respect to such Holder as such Holder reasonably requests to be
     included therein and (ii) make all required filings of such Prospectus
     supplement or such post-effective amendment as soon as the Company has
     received satisfactory notification of the matters to be incorporated in
     such filing; and


<PAGE>

          (q)  in the case of a Shelf Registration, use its best efforts to
     enter into such customary agreements and take all such other reasonable
     actions in connection therewith (including those requested by the
     Holders of a majority in aggregate principal amount of the Registrable
     Notes being sold) in order to expedite or facilitate the disposition of
     such Registrable Notes including, but not limited to, an Underwritten
     Offering and in such connection, (i) to the extent possible, make such
     representations and warranties to the Holders and any Underwriters of
     such Registrable Notes with respect to the business of the Company and
     its subsidiaries and its or its subsidiaries' joint ventures, the
     Registration Statement, Prospectus and documents incorporated by
     reference or deemed incorporated by reference, if any, in each case, in
     form, substance and scope as are customarily made by issuers to
     underwriters in Underwritten Offerings and confirm the same if and when
     requested, (ii) obtain opinions of counsel to the Company (which counsel
     and opinions, in form, scope and substance, shall be reasonably
     satisfactory to the Holders of a majority in aggregate principal amount
     of the Registrable Notes to be sold in such Underwritten Offering and
     any Underwriters and their respective counsel) addressed to each selling
     Holder and any Underwriter of Registrable Notes, covering the matters
     customarily covered in opinions requested in Underwritten Offerings,
     (iii) obtain "cold comfort" letters from the independent certified
     public accountants of the Company (and, if necessary, any other
     certified public accountant of any subsidiary of the Company or any
     joint venture in which the Company or any of its subsidiaries is a
     partner, or of any business acquired by the Company for which financial
     statements and financial data are or are required to be included in the
     Registration Statement) addressed to each selling Holder and any
     Underwriter of Registrable Notes, such letters to be in customary form
     and covering matters of the type customarily covered in "cold comfort"
     letters in connection with Underwritten Offerings, and (iv) deliver such
     documents and certificates as may be reasonably requested by the Holders
     of a majority in aggregate principal amount of the Registrable Notes
     being sold or any Underwriter, and which are customarily delivered in
     Underwritten Offerings, to evidence the continued validity of the
     representations and warranties of the Company made pursuant to clause
     (i) above and to evidence compliance with any customary conditions
     contained in an underwriting agreement; provided that the Company shall
     be required to use its best efforts to make an Underwritten Offering
     only upon the request of Holders of at least 25 % of the Registrable
     Notes outstanding at the time such request is delivered to the Company.
     In the case of any Underwritten Offering, the Company shall provide
     written notice to the Holders of all Registrable Notes of such
     Underwritten Offering at least 30 days prior to the filing of a
     prospectus supplement for such Underwritten Offering, (y) specify a
     date, which shall be no earlier than 10 days following the date of such
     notice, by which each 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.

          In the case of a Shelf Registration Statement, the Company may
require each Holder of Registrable Notes to furnish to the Company such
information regarding the Holder and the proposed distribution by such Holder
of such Registrable Notes as the Company may from time to time reasonably
request in writing.  Each such Holder shall provide the Company with any such
information within five business days after such information is requested and
shall provide to the Company, within five business days after such Holder
receives a draft of the Registration Statement or amendment thereto in which
such information is included, comments on such Registration Statement or
amendment thereto.  A Holder of Registrable Notes shall not be entitled to
receive additional interest pursuant to Section 2 of the Notes to the extent
that such Holder fails to comply with any obligation under this paragraph and
the failure by such Holder to comply with such obligation is the sole reason
for the accrual of additional interest pursuant to Section 2 of the Notes.


<PAGE>

          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 of the kind described in Section 3(e)(iii), (v) or (vi) hereof, such
Holder will forthwith discontinue disposition of Registrable Notes pursuant
to such Shelf Registration Statement until such Holder's receipt of the
copies of the supplemented or amended Prospectus contemplated by Section 3(i)
hereof and, if so directed by the Company, such Holder will deliver to the
Company (at its expense) all copies in its possession, other than permanent
file copies then in such Holder's possession, of the Prospectus covering such
Registrable Notes current at the time of receipt of such notice.

          4.  Participation of Broker-Dealers in Exchange Offer.  (a)  The
Staff of the SEC has taken the position that any broker-dealer that receives
Exchange Notes for its own account in the Exchange Offer in exchange for
Notes 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 Securities Act and must
deliver a prospectus meeting the requirements of the Securities 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 containing a statement to the above effect and the means
by which Participating Broker-Dealers may resell the Exchange Notes, without
naming the Participating Broker-Dealers or specifying the amount of Exchange
Notes owned by them, such Prospectus may be delivered by Participating
Broker-Dealers to satisfy their prospectus delivery obligation under the
Securities Act in connection with resales of Exchange Notes for their own
accounts, so long as the Prospectus otherwise meets the requirements of the
Securities Act.

          (b)  In light of Section 4(a) above, notwithstanding the other
provisions of this Agreement, the Company agrees 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 reasonable
modifications thereto as may be reasonably requested by the Initial Purchaser
or by 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 Notes by Participating Broker-Dealers consistent with the positions
of the Staff recited in Section 4(a) above; 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(i), for a period
     exceeding one year after the last Exchange Date (as extended by the
     number of days during such one-year period from, and including the date
     of, the giving by the Company of a notice pursuant to Section 3(e)(iii),
     (v) or (vi) of this Agreement to, and including the date when, the
     Company shall have made available to the Holders copies of a
     supplemented or amended Prospectus pursuant to Section 3(i) hereof) 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 4; and


<PAGE>

           (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 Securities Act and the rules and regulations thereunder, will be in
     conformity with the reasonable request to the Company in writing 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 are, or 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, (x) Section 3(n) shall not
     be applicable and (y) the Company shall be obligated (A) 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, (B) to pay reasonable 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 (C) to cause to be delivered only one, if any, "cold comfort"
     letter with respect to the Prospectus in the form existing on the last
     Exchange Date and with respect to each subsequent amendment or
     supplement, if any, effected during the period specified in clause (i)
     above.

          (c)  The Initial Purchaser shall have no liability to the Company
or any Holder with respect to any request that it may make pursuant to
Section 4(b) above.

          5.  Indemnification and Contribution. (a) The Company agrees to
indemnify and hold harmless the Initial Purchaser, each Holder and each
person, if any, who controls the Initial Purchaser or any Holder within the
meaning of either Section 15 of the Securities Act or Section 20 of the
Exchange Act or is under common control with or is controlled by the Initial
Purchaser or any Holder and each of their respective directors and officers
(each a "Non-Company Indemnitee") from and against any and all losses,
claims, damages, liabilities and expenses (including, without limitation, any
legal or other expenses reasonably incurred by the Non-Company Indemnitee in
connection with defending or investigating any such action or claim) arising
out of or based upon any untrue statement or alleged untrue statement of a
material fact contained in any Registration Statement (or any amendment or
supplement thereto) pursuant to which Exchange Notes or Registrable Notes
were registered under the Securities Act, including all documents
incorporated therein by reference, or arising out of or based upon 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, or
arising out of or based upon any untrue statement or alleged untrue statement
of a material fact contained in any Prospectus (as amended or supplemented,
if the Company shall have furnished any amendments or supplements thereto),
or caused by any omission or alleged omission to state therein a material
fact necessary to make the statements therein in light of the circumstances
under which they were made not misleading, except insofar as such losses,
claims, damages, liabilities or expenses arise out of or are based upon any
untrue statement or omission or alleged untrue statement or omission which
has been made therein or omitted therefrom in reliance upon and in conformity
with information relating to the Initial Purchaser or any Holder furnished to
the Company in writing by the Initial Purchaser or any selling Holder
expressly for use therein; provided, however, that the indemnification
provided for in this paragraph (a) shall not inure to the benefit of any Non-
Company Indemnitee with respect to any sale or disposition of Registrable
Notes by such Holder in violation of the provisions of the last paragraph of
Section 3 hereof.  In connection with any Underwritten Offering contemplated
by Section 3(q), the Company also shall indemnify the Underwriters, if any,
selling brokers, dealers and similar securities industry professionals
participating in the distribution, their officers and directors and each
person who controls such persons (within the meaning of the Securities Act
and the Exchange Act) to the same extent as provided above with respect to
the indemnification of the Holders, if requested in connection with any
Registration Statement.  The indemnification obligation of the Company set
forth in this paragraph (a) shall be in addition to any liability which the
Company may otherwise have, including, without limitation, for any breach of
any covenant contained in this Agreement.


<PAGE>

          (b)  Each Holder agrees, severally and not jointly, to indemnify
and hold harmless the Company, the Initial Purchaser, the other selling
Holders, each of their respective directors and officers and each person, if
any, who controls the Company, the Initial Purchaser, or any other selling
Holder within the meaning of either Section 15 of the Securities Act or
Section 20 of the Exchange Act or is under common control with or is
controlled by the Company, the Initial Purchaser or any other selling Holder
to the same extent as the foregoing indemnity from the Company to the Initial
Purchaser and the Holders, but only with reference to information relating to
such Holder furnished to the Company in writing by such Holder expressly for
use in the Registration Statement (or any amendment thereto) or any
Prospectus (or any amendment or supplement thereto).

          (c)  If any action, suit or proceeding shall be instituted
involving any person in respect of which such person is entitled to indemnity
pursuant to either paragraph (a) or (b) above, such person (the "indemnified
party") shall promptly notify the parties against whom indemnification is
being sought (the "indemnifying party") and such indemnifying parties shall
assume the defense thereof, including the employment of counsel and payment
of all fees and expenses.  Such indemnified party, shall have the right to
counsel, but the fees and expenses of such counsel shall be at the expense of
such indemnified party unless (i) the indemnifying parties have agreed in
writing to pay such fees and expenses, (ii) the indemnifying parties shall
have 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 indemnifying parties and such indemnified party
and such indemnified party shall have been advised by its counsel that
representation of such indemnified party and any indemnifying party 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 indemnifying parties shall not have the right to assume
the defense of such action, suit or proceeding on behalf of the indemnified
party).  It is understood, however, that the indemnifying parties shall, in
connection with any one such action, suit or proceeding or but substantially
similar proceeding 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 the Initial
Purchaser and all persons, if any, who control the Initial Purchaser within
the meaning of either Section 15 of the Securities Act or Section 20 of the
Exchange Act or is under common control with or is controlled by the Initial
Purchaser, and each of their respective directors and officers, and the
reasonable fees and expenses of only one separate firm of attorneys (in
addition to any local counsel) at any time for all Holders and all persons,
if any, who control any Holders within the meaning of either such Section, or
are under common control with or are controlled by such Holders, and each of
their respective directors and officers.  In such case involving the Initial
Purchaser, persons who control, are controlled by or under common control
with the Initial Purchaser, or their respective directors or officers, such
firm shall be designated in writing by the Initial Purchaser.  In such case
involving the Holders and such persons who control, are controlled by or
under common control with Holders, or their respective directors or officers,
such firm shall be designated in writing by the Holders of a majority of the
aggregate principal amount of Registrable Notes sold under the applicable
Registration Statement.  The indemnifying parties shall not be liable for any
settlement of any action, suit or proceeding effected without their written
consent, but if settled with such written consent or if there be a final
judgment for the plaintiff, the indemnifying parties agree to indemnify and
hold harmless the indemnified party from and against any loss, action,
damage, liability or expense by reason of such settlement or judgment.

<PAGE>

          (d)  If the indemnification provided for in this Section 5 is
unavailable to an indemnified party under paragraphs (a) or (b) 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 in
such proportion as is appropriate to reflect the relative fault of the
indemnifying party or parties, on the one hand, and of the indemnified party
or parties, on the other hand, in connection with such statements or
omissions that resulted in such losses, claims, damages, liabilities or
expenses as well as any other relevant equitable consideration.  The relative
fault of the Company, on the one hand, and any Holder, 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 such Holder, on the other hand, and the
parties* relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission.  The Holders' respective
obligations to contribute pursuant to this Section 5(d) are several in
proportion to the respective principal amount of Registrable Notes of such
Holder that were registered pursuant to the applicable Registration
Statement.

          (e)  The Company, the Initial Purchaser and each Holder agree that
it would not be just or equitable if contribution pursuant to this Section 5
were determined by a pro rata allocation 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 and liabilities 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 5, no Holder shall be required to contribute any amount in excess of
the amount by which the total price at which the Registrable Notes sold by
such Holder exceeds the amount of any damages that such Holder has 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 Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.  The remedies provided for in this Section 5
are not exclusive and shall not limit any rights or remedies that may
otherwise be available to any indemnified party at law or in equity.

          (f)  Any losses, claims, damages, liabilities or expenses for which
an indemnified party is entitled to indemnification or contribution under
this Section 5 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 5 and the
representations of the Company contained in this Agreement shall remain
operative and in full force and effect, regardless of (i) any investigation
made by or on behalf any indemnified person, (ii) acceptance of any of the
Exchange Notes, (iii) any sale of Registrable Notes pursuant to a Shelf
Registration Statement and (iv) any termination of this Agreement.  A
successor to any indemnified party shall be entitled to the benefits of the
indemnity, contribution and reimbursement agreements contained in this
Section 5.

          (g)  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.

<PAGE>

          6.  Miscellaneous.  (a)  No Inconsistent Agreements.  The Company
has not entered into, and on or after the date of this Agreement will not
enter into, any agreement that is inconsistent with the rights granted to the
Holders of Registrable Notes in this Agreement or otherwise conflicts with
the provisions hereof.  The rights granted to the Holders hereunder do not in
any way 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.

          (b)  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 Notes affected by such amendment, modification,
supplement, waiver or departure; provided, however, that no amendment,
modification, supplement, waiver or consent to the departure with respect to
the provisions of Section 5 hereof shall be effective as against any person
unless consented to in writing by such person.

          (c)  Notices.  All notices and other communications provided for or
permitted hereunder shall be made in writing by hand-delivery, registered
first-class mail, telex, telecopier or any courier guaranteeing overnight

to the Company by means of a notice given in accordance with the provisions
of this Section 6(c), which address initially is, with respect to the Initial
Purchaser, the address set forth in the Purchase Agreement; and (ii) if to
the Company, initially at the Company's address set forth in the Purchase
Agreement, and, thereafter, at such other address, notice of which is given

duly given: at the time delivered by hand, if personally delivered; five
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 overnight delivery.

          Copies of all such notices, demands, or other communications shall
be concurrently delivered by the person giving the same to the Trustee, at
the address specified in the Indenture.

          (d)  Successors and Assigns.  This Agreement shall inure to the
benefit of and be binding upon the successors, assigns and transferees of
each of the parties, including, without limitation and without the need for
an express assignment, subsequent Holders; provided that nothing herein shall
be deemed to permit any assignment, transfer or other disposition of
Registrable Notes in violation of the terms of the Purchase Agreement.  If
any transferee of any Holder shall acquire Registrable Notes, in any manner,
whether by operation of law or otherwise, such Registrable Notes shall be
held subject to all of the terms of this Agreement, and by taking and holding
such Registrable Notes, such person shall be conclusively deemed to have
agreed to be bound by and to perform all of the terms and provisions of this
Agreement and such person shall be entitled to receive the benefits hereof.
The Initial Purchaser (in its capacity as Initial Purchaser) shall have no
liability or obligation to the Company with respect to any failure by any
other Holder to comply with, or any breach by any other Holder of, any of the
obligations of such other Holder under this Agreement.

          (e)  Purchases and Sale of Notes.  The Company shall not, and shall
use its best efforts to cause its affiliates (as defined in Rule 405 under
the Securities Act) that it controls not to, purchase and then resell or
otherwise transfer any Notes.

          (f)  Third Party Beneficiary.  The Holders shall be third party
beneficiaries to the agreements made hereunder between the Company, on the
one hand, and the Initial Purchaser, on the other hand, and the Initial
Purchaser and the Holders shall have the right to enforce such agreements
directly to the extent they deem such enforcement necessary or advisable to
protect the rights of the Initial Purchaser or the Holders hereunder.

<PAGE>

          (g)  Counterparts.  This Agreement may be signed in various
counterparts which 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.

          (h)  Headings.  The headings of the Sections of this Agreement have
been inserted for convenience of reference only and shall not be deemed a
part of this Agreement.

          (i)  Governing Law.  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 in the State of New York.

          (j)  Severability.  In the event that any one or more of the
provisions contained herein, or the application thereof in any circumstance,
is held invalid, illegal or unenforceable, the validity, legality and
enforceability of any such provision in every other respect and of the
remaining provisions contained herein shall not be affected or impaired
thereby.

          (k)  Submission to Jurisdiction.  The Company irrevocably submits
to the jurisdiction of any United States or State court located in the State
of New York in any suit or proceeding based on or arising under this
Agreement and irrevocably agrees that all claims in respect of such suit or
proceeding may be determined in any such court.  The Company irrevocably
waives the defense of an inconvenient forum to the maintenance of such suit
or proceeding.  The Company hereby agrees to designate and appoint CT
Corporation System as an agent upon whom process may be served in any suit or
proceeding based on or arising under this Agreement.  The Company further
agrees that service of process upon the Company, or upon an agent appointed
pursuant to the preceding sentence accompanied with written notice of said
service to the Company, as the case may be, mailed by first class mail shall
be deemed in every respect effective service of process upon the Company in
any such suit or proceeding.  Nothing herein shall affect the Initial
Purchaser's or any Holder's right to serve process in any other manner
permitted by law.  The Company agrees that a final non-appealable judgment in
any such suit or proceeding shall be conclusive and may be enforced in other
jurisdictions by suit on such judgment or in any other lawful manner.

          A.   Geotek and the Collateral Agent are parties to an Indenture
dated as of the date hereof (as the same may be amended, modified, extended
or replaced from time to time, the "Indenture").

          B.   The Pledgor is the legal and beneficial owner of all of the
Pledged Securities (as hereinafter defined), which consists of the capital
stock issued by the Pledgor's subsidiaries listed in Schedule I hereto
(collectively, the "Issuer"), as such Schedule may be amended from time to
time.

          C.   The execution and delivery of this Agreement by Pledgor is a
condition precedent to the issuance of the Securities under the Indenture.

          NOW, THEREFORE, for good and valuable consideration received, the
receipt and sufficiency of which are hereby acknowledged, the parties hereto
agree as follows:

                             ARTICLE 1. DEFINITIONS
          1.1  Terms Defined in Indenture.  Capitalized terms used in this
Agreement without definition have the meanings set forth in the Indenture.

     thereto.

          2.6  No Obligations Undertaken.  Nothing contained in this
Agreement shall relieve Pledgor of, or except as otherwise expressly provided
in this Agreement or the Indenture, impose on the Collateral Agent, any
obligation or liability with respect to the Pledged Collateral.  The
Collateral Agent shall not have any duty or responsibility for (a) taking
action with respect to calls, conversions, exchanges, maturities tenders or
other matters relating to any of the Pledged Collateral, whether or not the
Collateral Agent has or is deemed to have knowledge of such matters, or (b)
taking any necessary steps to preserve rights against third parties or
pertaining to the Pledged Collateral.  The Collateral Agent may rely on any
information provided to it by any accountants or advisors of Pledgor or of
Collateral Agent in acting hereunder.

                   ARTICLE 3. REPRESENTATIONS AND WARRANTIES

          3.1  Pledged Securities.  The Pledged Securities constitute all the
issued and outstanding shares of all classes of the capital stock of each
Issuer owned by Pledgor, are validly issued, fully paid and non-assessable
and are not subject to any restriction on alienation or transfer (including,
without limitation, any transfer restrictions under any shareholder or
similar agreements) other than pursuant to this Agreement and applicable
securities and telecommunications laws.

          3.2  Title.  Pledgor is the legal and beneficial owner of all
right, title and interest in, to and under the Pledged Securities, and,
except for 75,000 shares of EGAC common stock to be hereafter acquired by
Pledgor, there are no outstanding rights (including, without limitation,
rights of first offer or refusal), options, warrants, conversion rights or
other commitments or agreements for the purchase or acquisition of the
Pledged Securities.

          3.3  No Liens or Prior Pledges.  Pledgor has not granted any other
security interest in or made any prior pledges of any of the Pledged
Collateral, except which was previously released, terminated and fully
extinguished, and the Pledged Collateral is (and as to any of the Pledged
Collateral hereafter acquired, will be upon acquiring same) free of all
liens, pledges, security interests and encumbrances other than those in favor
of the Collateral Agent, except for an option to be granted to certain
members of management of EGAC to purchase from Pledgor up to 75,000 shares of
EGAC common stock.

          3.4  Authority, Etc.  Pledgor has all requisite corporate power and
authority to execute and deliver this Agreement, and all necessary action has
been taken to duly authorize Pledgor's execution, delivery and performance of
this Agreement.  The execution, delivery and performance of this Agreement by
Pledgor will not result in (a) a default under any contract, agreement or
instrument to which Pledgor is a party or by which Pledgor is bound, or (b) a
violation of any statutes, laws, rules or regulations (the "Legal
Requirements") applicable to Pledgor, except for such defaults or violations
which would not have a material adverse effect on Pledgor and its
subsidiaries taken as a whole or the Pledged Collateral.  This Agreement is
the legal, valid and binding obligation of Pledgor enforceable against
Pledgor in accordance with its terms, except as such enforceability may be
limited by the effect of any applicable bankruptcy, insolvency,
reorganization, moratorium or other similar laws affecting creditors' rights
generally or general principles of equity.

          3.5  Government Approvals.  Except as otherwise provided in Section
5.4 hereof, no approval or action by, and no notice to, any governmental
authority or regulatory body is required in connection with the execution,
delivery and performance of this Agreement by Pledgor, except as may be
required under applicable securities laws and except as may be required by
the Federal Communications Commission (the "FCC") under certain
circumstances.

for the perfection of the security interest granted in the Pledged
Securities, and all necessary consents of third parties to the granting of
such security interest and the execution, delivery and performance of this
Agreement have been duly obtained.  Upon possession (and assuming continued
possession thereof) of the Pledged Securities, the Collateral Agent will have
a valid, perfected, first priority security interest in all of Pledgor's
right, title, interest, claims, powers and privileges in, to and under the
Pledged Securities.

          3.7  Name.  The correct legal name of Pledgor is as set forth in

constituting margin stock pursuant to this Agreement does not violate
Regulations G or U or any other regulations of the Board of Governors (within
the meaning of Regulation G of the Board of Governors of the Federal Reserve
System) or any other material Legal Requirements, except for such violations
which would not have a material adverse effect on Pledgor and its
subsidiaries taken as a whole or the Pledged Collateral.

                              ARTICLE 4. COVENANTS

          4.1  Covenants of Pledgor.  Pledgor hereby covenants and agrees to
and with the Collateral Agent as follows:

               4.1.1  Maintenance of Security Interests.  Pledgor shall from
time to time execute and deliver to the Collateral Agent such financing
statements, continuation statements, financing statement amendments or other
filings or documents, and take such other steps, as the Collateral Agent may
reasonably require to further assure to the Collateral Agent its rights under
this Agreement.

               4.1.2  No Other Pledge or Liens.  Pledgor shall not permit the
Pledged Companies (other than EGAC) and their direct and indirect
subsidiaries (including any entities controlled by a Pledged Company through
the ownership of voting securities, by contract or otherwise) to, directly or
indirectly, create, incur, permit to exist, pledge or grant a security
interest in, or Lien on, any of their respective properties, assets or
proceeds therefrom (except for Permitted Pledge Agreement Liens).  Except as
otherwise provided herein or in the Indenture, Geotek shall maintain and
defend the Pledged Collateral (and the collateral pledged to the Collateral
Agent pursuant to the other Pledge Agreements), and, shall cause the Pledged
Companies (other than EGAC) and their direct and indirect subsidiaries
(including any entities controlled by a Pledged Company (other than EGAC)
through the ownership of voting securities, by contract or otherwise) to
maintain and defend their respective properties, assets and proceeds
therefrom against any adverse claims (other than Permitted Pledge Agreement
Liens).  If Geotek shall have (i) 50,000 Qualified GEONET Subscribers at the
end of the most recently completed billing month and (ii) positive Operating
Cash Flow in any two of its GEONET markets for the most recently completed
fiscal quarter, Geotek may, to the extent otherwise permitted in this
Agreement and the Indenture, grant a security interest, that is equal and
ratable to the security interest granted to the Collateral Agent, in the
Pledged Collateral consisting of capital stock of Pledged Companies that,
directly or indirectly, hold, or hold any rights in, Licenses for U.S. 900
MHz radio channels; provided that such security interest shall not secure
Indebtedness in an amount in excess of the product of $1,500 and the number
of Qualified GEONET Subscribers as of the end of the most recently completed
billing month.


<PAGE>

               4.1.3  Indebtedness.  Pledgor shall not permit the Pledged
Companies (other than EGAC) and their direct and indirect subsidiaries
(including any entities controlled by a Pledged Company (other than EGAC)
through the ownership of voting securities, by contract or otherwise) to
directly or indirectly, create, incur, issue, assume, guarantee or in any
manner become directly or indirectly liable (contingently or otherwise) for
any Indebtedness (including, without limitation, any Acquired Indebtedness)
other than Permitted Pledge Agreement Indebtedness; provided that the
aggregate outstanding Indebtedness of the Pledged Companies (excluding
Indebtedness owed to other Pledged Companies or Geotek and Indebtedness of
EGAC) at any time shall not exceed $62,000,000.

               4.1.4  No Transfers.  Except pursuant to the terms of this
Agreement or the Indenture (including, without limitation, transactions
contemplated by Section 7.14 hereof), Pledgor shall not sell, assign,
transfer or otherwise dispose of, or grant any option with respect to, the
Pledged Collateral (or the collateral pledged to the Collateral Agent
pursuant to the other Pledge Agreements).  Notwithstanding the foregoing,
Pledgor shall be permitted to grant options covering up to 75,000 shares of
common stock of EGAC hereafter acquired by Pledgor to certain members of
management of EGAC.

               4.1.5  Removal of Certain Legends.  In the event any of the
certificates delivered by Pledgor to the Collateral Agent under Article 2 of
this Agreement bears any legend purportedly restricting transferability of
the Pledged Securities evidenced by such certificates (other than legends
with respect to restrictions imposed under applicable securities laws),
Pledgor shall, at the request of the Collateral Agent, use reasonable efforts
to obtain and deliver to the Collateral Agent certificates which do not bear
any legends (other than legends with respect to restrictions imposed under
applicable securities laws).

               4.1.6  Change of Name.  Upon any change of Pledgor's legal
name or location of its chief executive office, Pledgor shall notify the
Collateral Agent twenty (20) days prior to such change in writing and shall
take such action as the Collateral Agent may reasonably request to assure to
the Collateral Agent the continued perfection of the security interest
granted under this Agreement.

               4.1.7  Notices.  Pledgor will provide the Collateral Agent
with any and all notices or material items received by Pledgor relating to
the Pledged Securities.

               4.1.8  Covenants in Indenture.  Subject to Section 7.15
hereof, Pledgor agrees to comply (and to cause the Pledged Companies to
comply) with all covenants and agreements with respect to such person set
forth in the Indenture.

               4.1.9  EGAC Shares.  Pledgor covenants and agrees that, upon
the consummation of the acquisition by EGAC of Geotek's interest in Bogen and
Speech Design pursuant to the Acquisition Agreement, the Pledgor shall pledge
to the Collateral Agent all of the Capital Stock of EGAC owned by Geotek at
such time and such Capital Stock shall automatically constitute Pledged
Securities hereunder.


<PAGE>

               4.1.10  Additional Subsidiary Pledges.  (a)  Pledgor covenants
and agrees that if Geotek transfers the Capital Stock of any Pledged Company
to any person in exchange for Capital Stock of such person (including
pursuant to a transaction described in clause (k) of the definition of
"Permitted Investments" contained in the Indenture) ("Non-Pledged Stock"), or
any Pledged Company transfers or causes to be transferred, directly or
indirectly, in one or a series of related transactions, property or assets
(including, without limitation, businesses, divisions, real property, assets
or equipment) having a fair market value (as determined in good faith by the
board of directors of Geotek evidenced by a resolution of the board of
directors of Geotek set forth in an Officers' Certificate delivered to the
Collateral Agent) exceeding $2.0 million to such person or any subsidiary of
Geotek that is not a Pledged Company, then Geotek shall (a) enter into a
pledge agreement (or an amendment to this Agreement) in order to pledge all
of such Non-Pledged Stock or the outstanding Capital Stock of such
subsidiary, as the case may be, owned by Geotek as security to the Collateral
Agent for the benefit of the holders of the Securities and (b) deliver to the
Collateral Agent an Opinion of Counsel reasonably satisfactory to the
Collateral Agent that such pledge agreement (or amendment to this Agreement)
has been duly authorized, executed and delivered, is enforceable and creates
a valid and perfected first priority security interest in such Non-Pledged
Stock or Capital Stock; provided, however, that the provisions of this
Section 4.1.10 will not apply to (A) transfers of property or assets (other
than cash) by a Pledged Company to Geotek or a subsidiary that is not a
Pledged Company in exchange for cash in an amount equal to the fair market
value (as determined in good faith by the board of directors of Geotek
evidenced by a resolution of the board of directors of Geotek set forth in an
Officers' Certificate delivered to the Collateral Agent) of such property or
assets or (B) Restricted Payments and Investments (other than a Permitted
Investment within the meaning of clause (k) of the definition of "Permitted
Investments" contained in the Indenture) permitted by the Indenture.

               (b)  In the event that any Pledged Company transfers or causes
     to be transferred to any person directly or indirectly, in one or a
     series of related transactions, property or assets (including, without
     limitation, businesses, divisions, real property, assets or equipment)
     having a fair market value (as determined in good faith by the board of
     directors of Pledgor evidenced by a resolution of the board of directors
     of Pledgor and set forth in an Officers' Certificate delivered to the
     Collateral Agent) exceeding $2.0 million to any such person, the Net
     Cash Proceeds resulting from the sale or other disposition of such
     property or assets shall, to the extent permitted by law, be immediately
     deposited in the Collateral Account (as hereinafter defined) and Pledgor
     shall cause any non-cash proceeds from such sale or other disposition
     (including securities) received by Pledgor or a subsidiary to
     immediately become subject to a first priority perfected Lien in favor
     of the Collateral Agent.  Any Net Cash Proceeds resulting from such sale
     or disposition shall be required to be applied in accordance with
     Section 7.14 hereof.

               (c)  Notwithstanding any other provision contained herein, if
     Pledgor transfers any FCC license to any wholly-owned subsidiary of
     Pledgor that is not a Pledged Company, all of the Capital Stock of such
     subsidiary shall be pledged to the Collateral Agent as additional
     Pledged Collateral.

<PAGE>

                        ARTICLE 5. DEFAULT AND REMEDIES

          5.1  Remedies.  Subject to the receipt of any necessary approvals
from the FCC (as more particularly described in Section 5.4) or similar
foreign agency (and to the extent permitted by law), after the occurrence and
during the continuance of an Event of Default, the Collateral Agent shall
have, in addition to any other rights or remedies the Collateral Agent may
have under the Indenture or any of the other Transaction Documents or at law
or in equity or otherwise, any or all of the following rights and remedies:

               5.1.1  Rights of Secured Party.  The Collateral Agent may
exercise all of the rights and remedies of a secured party under the UCC and
under any other applicable laws.

               5.1.2  Exercise of Rights Under Pledged Collateral.  Pledgor's
rights under Section 2.5 shall automatically terminate, and the Collateral
Agent may exercise any or all of Pledgor's rights in respect of the Pledged
Collateral, including without limitation the right to vote any or all of the
shares included in the Pledged Collateral and to receive all cash or other
distributions in respect of such shares.  Any cash or other distributions in
respect of the Pledged Collateral received by Pledgor after the occurrence
and during the continuance of an Event of Default shall be held in trust for
the Collateral Agent and promptly paid over to the Collateral Agent.  Pledgor
agrees to execute any document or instrument reasonably required by the
Collateral Agent to effect the foregoing.

               5.1.3  Sale of Pledged Collateral.  The Collateral Agent may
sell any or all of the Pledged Collateral by public or private sale or at any
broker's board or on any securities exchange.  The following provisions shall
apply with respect to any such sale:

                    (a)  any such sale may be for cash, upon credit or for
     future delivery, as the Collateral Agent in its sole discretion shall
     deem appropriate;

                    (b)  to the extent permitted by applicable law, the
     Collateral Agent may, in its sole discretion, restrict the prospective
     bidders or purchasers to a limited number of sophisticated investors who
     represent and agree that they are purchasing for their own account for
     investment and not with a view to distribution or resale, and any
     purchaser of any of the Pledged Collateral shall hold same free from any
     claim or right on the part of Pledgor;

                    (c)  at any such sale the Collateral Agent may, to the
     extent permitted by applicable law, bid for or purchase any or all of
     the Pledged Collateral, free from any claim or right on the part of
     Pledgor, and upon compliance with the terms of sale, may to the extent
     permitted by applicable law, hold, retain and dispose of same without
     further accountability therefor;

                    (d)  the Collateral Agent shall give to Pledgor at least
     10 days' written notice of any such sale, which is hereby agreed to be
     reasonable notice;

                    (e)  any such public sale shall be held at such time or
     times within ordinary business hours and at such place or places as the
     Collateral Agent may fix in the notice of such sale;

                    (f)  at any such sale, any of the Pledged Collateral may
     be sold in one lot or in separate parcels as the Collateral Agent may in
     its sole discretion determine;

                    (g)  the Collateral Agent shall not be obligated to make
     any sale of any or all of the Pledged Collateral regardless of the fact
     that notice of sale may have been given, and, to the extent permitted by
     applicable law, the Collateral Agent may, without notice or publication,
     adjourn any such sale or cause the same to be adjourned from time to
     time by announcement at the time and place fixed for sale, and, to the
     extent permitted by applicable law, such sale may without further notice
     be made at the time and place to which the same shall have been so
     adjourned;


<PAGE>

                    (h)  in the event that the sale of any or all of the
     Pledged Collateral is made on credit or for future delivery, the Secured
     Obligations shall be reduced at the time of such payment by the full
     amount thereof.  The Pledged Collateral shall be retained by the
     Collateral Agent until the selling price is paid.  The Collateral Agent
     shall incur no liability should purchaser not pay for the Pledged
     Collateral.  In such event, the Pledged Collateral may be resold as
     herein provided;

                    (i)  in the event compliance with any federal or state
     laws or foreign law of pledges is required in connection with any such
     sale, Pledgor shall take all reasonable steps as may be reasonably
     required to enable the Collateral Agent to effect any such sale of any
     or all of the Pledged Collateral in compliance with such federal or
     state laws or foreign law of pledges; provided, however, that Pledgor
     shall not be required to register the Pledged Securities under the
     Securities Act of 1933, as amended (or any similar foreign law);

                    (j)  Pledgor acknowledges and agrees that compliance with
     any such federal or state laws or foreign law of pledges may severely
     impair the Collateral Agent's ability to promptly dispose of any or all
     of the Pledged Collateral, and thereby agrees that, notwithstanding the
     existence of a public or private market upon which the quotation or
     sales prices for any or all of the Pledged Collateral may exceed
     substantially the price at which the Collateral Agent sells same, it
     would be commercially reasonable for the Collateral Agent to:

                         (1)  sell all or any part of the Pledged Collateral
          to a purchaser without soliciting purchasers even if a higher price
          could have been obtained pursuant to a broader solicitation;

                         (2)  place all or any part of the Pledged Collateral
          with an investment banking firm for sale by private placement; or

                         (3)  sell all or any part of the Pledged Collateral
          to an investment banking firm for its own account if otherwise
          commercially reasonable.

               5.1.4  Judicial Foreclosure.  The Collateral Agent may proceed
by a suit or suits at law or in equity to foreclose on and to sell any or all
of the Pledged Collateral pursuant to a judgment decree of a court or courts
of competent jurisdiction.

               5.1.5  Notices.  The remedies herein do not require the
Collateral Agent to give any notice except as provided herein or required by
mandatory provisions of law.

          5.2  Application of Proceeds.  All proceeds realized by the
Collateral Agent in respect of any or all of the Pledged Collateral,
including the proceeds of any sale thereof or any cash distributed in respect
of any of the Pledged Collateral shall be applied against the Secured
Obligations in accordance with the Indenture.  To the extent permitted by
applicable law, Pledgor shall be liable for any deficiency, and any surplus
shall be returned by the Collateral Agent to the person or persons legally
entitled thereto.

          5.3  Cumulative Remedies.  All rights and remedies of the
Collateral Agent are separate and cumulative, and no one of them, whether
exercised or not, shall be deemed to be to the exclusion of or to limit or
prejudice any other legal or equitable rights or remedies which the
Collateral Agent may have.

<PAGE>

          5.4  FCC MATTERS.
               (a)  If an Event of Default shall have occurred and be
     continuing, Pledgor shall take any action which the Collateral Agent may
     request in the exercise of its rights and remedies under this Agreement
     to transfer and assign to the Collateral Agent, or to such one or more
     third parties as the Collateral Agent may designate, or to a combination
     of the foregoing, the Pledged Collateral.  To enforce the provisions of
     this Section 5.4, the Collateral Agent is hereby empowered to seek from
     the FCC an involuntary transfer of control of any Subsidiary for the
     purpose of seeking a bona fide purchaser to whom control will ultimately
     be transferred.  If an Event of Default shall have occurred and be
     continuing, Pledgor hereby agrees to authorize such an involuntary
     transfer of control upon the request of the Collateral Agent.  Upon the
     occurrence and continuation of an Event of Default, Pledgor shall use
     its best efforts to assist in obtaining approval of the FCC, if
     required, for any action or transactions contemplated by this Agreement,
     including, without limitation, the preparation, execution and filing
     with the FCC of Pledgor's portion of any application or applications for
     consent to transfer of control necessary or appropriate under the FCC's
     rules and regulations for approval of the transfer or assignment of any
     portion of the Pledged Collateral.

               (b)  Pledgor acknowledges that FCC authorization for the
     transfer of control of the licenses of Pledgor and the subsidiaries is
     integral to the Collateral Agent's realization of the value of the
     Pledged Collateral for the benefit of the holders of the Securities,
     that there is no remedy at law for failure by Pledgor to comply with the
     provisions of this Section 5.4 and that such failure would not be
     adequately compensable in damages, and therefore agrees that the
     agreements of Pledgor contained in this Section 5.4 may be specifically
     enforced.

               (c)  Notwithstanding anything to the contrary contained in
     this Agreement, the Collateral Agent shall not, without first obtaining
     approval of the FCC, take any action pursuant to this Agreement which
     would constitute or result in any change of control of Pledgor or any
     subsidiary if such change in control would require, under then existing
     law (including the written rules and regulations of the FCC), the prior
     approval of the FCC.

               (d)  Upon the occurrence and during the continuance of an
     Event of Default and subject to the other provisions of Section 5,
     Pledgor consents to the transfer of control or assignment of the Pledged
     Collateral to a receiver, trustee, transferee, or similar official or to
     any purchaser of the Pledged Collateral pursuant to any public or
     private sale, judicial sale, foreclosure or exercise of other remedies
     available to the Collateral Agent under this Agreement and as permitted
     by applicable law.

               (e)  Notwithstanding anything to the contrary contained in
     this Agreement, prior to the occurrence of an Event of Default and
     compliance with all applicable laws by the Collateral Agent, this
     Agreement and the transactions contemplated hereby do not, will not, and
     are not intended to, constitute, create or have the effect of
     constituting or creating, directly or indirectly, actual or practical
     ownership of Pledgor, any Pledged Company or any of their respective
     subsidiaries by the Collateral Agent or control, affirmative or
     negative, direct or indirect, of Pledgor, any Pledged Company or any of
     their respective subsidiaries, over the management or any other aspect
     of the operations of Pledgor, any Pledged Company or any of their
     respective subsidiaries, which ownership and control remain exclusively
     and at all times in Pledgor, the Pledged Companies and their respective
     subsidiaries.

                    ARTICLE 6. INDEMNIFICATION AND EXPENSES

          6.1  Indemnification.  Pledgor hereby unconditionally covenants and

of a material fact or omission of a material fact in a registration
statement, prospectus or other document (regardless of any investigations
made by the Collateral Agent), or Pledgor's defense of any and all claims and
demands whatsoever which may be asserted against Pledgor in connection with
this Agreement, or any action taken by Pledgor under this Agreement.

          6.2  Expenses.  Pledgor shall reimburse the Collateral Agent on
demand for all reasonable costs and expenses (including reasonable attorneys'
fees and disbursements) incurred by the Collateral Agent in connection with
the enforcement of this Agreement or the exercise by the Collateral Agent of
its rights or remedies under this Agreement, and all sums owing to the
Collateral Agent under this Section 6.2 shall be included in the Secured
Obligations and secured by this Agreement.

          7.2  Amendments, Supplements and Waivers.  No amendment, supplement
or waiver of any provision of this Agreement or of any right, power or remedy
under this Agreement shall be effective unless made in accordance with
Article Nine of the Indenture.  No failure by the Collateral Agent to
exercise, and no delay by the Collateral Agent in exercising, any right,
power or remedy granted under this Agreement shall operate as a waiver of any
such right, power or remedy.  A waiver of any right, power or remedy to the
Collateral Agent on any one occasion shall not be construed as a bar to or
waiver of any right, power or remedy on any future occasion.

          7.3  Assignments.  This Agreement shall not be assignable in whole
or in part by Pledgor.

          7.4  Successors and Assigns.  This Agreement inures to the benefit
of and binds Pledgor and the Collateral Agent and their respective permitted
successors and assigns.

          7.5  Governing Law.  This Agreement shall be construed, interpreted
and governed by the laws of the State of New York, without giving effect to
the principles of conflicts of law.

          7.6  Consent to Jurisdiction.  The parties hereto irrevocably
consent to the jurisdiction of the courts of the State of New York and any
federal court located in such state in connection with any action, suit or
proceeding arising out of or relating to this Agreement and irrevocably waive
the defense of an inconvenient forum to the maintenance of such suit or
proceeding.  Geotek hereby agrees to designate and appoint CT Corporation
System as an agent upon whom process may be served in any suit or proceeding
based on or arising under this Agreement.  Geotek further agrees that service
of process upon Geotek, or upon an agent appointed pursuant to the preceding
sentence accompanied with written notice of said service to Geotek, as the
case may be, mailed by registered mail shall be deemed in every respect
effective service of process upon Geotek in any such suit or proceeding.
Nothing herein shall affect the Collateral Agent's right to serve process in
any other manner permitted by law.  Geotek agrees that a final non-appealable
judgment in any such suit or proceeding shall be conclusive and may be
enforced in other jurisdictions by suit on such judgment or in any other
lawful manner.

          7.7  Severability.  If one or more of the provisions of this
Agreement shall be held to be invalid, illegal or unenforceable in any
respect under applicable law, the validity, legality or enforceability of the

extent it is legal and shall be applied in full in all other jurisdictions.

          7.8  Headings.  The titles and headings of the sections of this

intended to summarize or otherwise describe the subject matter of such
sections and shall not be used in construing such section.

          7.9  Counterparts.  This Agreement may be executed in counterparts,
each of which shall constitute an original, but all of which together shall
constitute one and the same instrument.

          7.10 Waiver of Jury Trial.  Pledgor and the Collateral Agent hereby
knowingly, voluntarily and intentionally waive any rights they may have to a
trial by jury in respect of any litigation based hereon, or arising out of,
under or in connection with this Agreement, the Indenture, the Securities or
any other Transaction Document, of any course of conduct, course of dealing,
statements (whether verbal or written), or actions of Pledgor or the
Collateral Agent.  This provision is a material inducement for Pledgor and
the Collateral Agent entering into this Agreement.

          7.11 Further Assurances and Power of Attorney.

               (a) Subject to the provisions of Section 5.4 hereof, Pledgor
     agrees to, as promptly as practicable, do such further acts and things, and
     to execute and deliver such additional assignments, agreements and
     instruments, as the Collateral Agent may at any time reasonably request in
     connection with the administration or enforcement of this Agreement or with
     respect to any or all of the Pledged Collateral, including, without
     limitation, obtaining necessary governmental approvals referred to herein,
     in order to assure and confirm to the Collateral Agent its rights, powers
     and remedies under this Agreement. In connection with such governmental
     approvals, the Pledgor hereby appoints the Collateral Agent and the
     Collateral Agent's designees as the Pledgor's attorney-in-fact with power
     to execute any and all documents, assignments, applications and other
     instruments necessary for such approvals.

               (b)  Pledgor further agrees to do such further acts and
     things, and to execute and deliver such additional assignments,
     agreements, instruments and UCC financing statements as the Collateral
     Agent may reasonably request to create, after the date hereof, in favor
     of the Collateral Agent, a first priority perfected Lien in any and all
     assets required to be pledged to the Collateral Agent hereunder,
     including, without limitation, an account pledge agreement and a blocked
     account agreement (each in form and substance satisfactory to the
     Collateral Agent) with respect to the Collateral Account.

          7.12 Security Interest Absolute.  All rights of the Collateral
Agent and security interests hereunder, and all obligations of the Pledgor
under this Agreement, shall be absolute and unconditional irrespective of (i)
any lack of validity or enforceability of any Secured Obligations or the
Transaction Documents; (ii) the absence of any attempt to collect any of the
Secured Obligations from the Pledgor or any other Person or of any other
action to enforce the same; (iii) any change of the time, manner or placement
of payment, or any other term, of any Secured Obligations; (iv) any exchange,
release or non-perfection of any collateral securing payment of any Secured
Obligations; (v) any law, regulation or order of any jurisdiction affecting
any term of any Secured Obligations or the Collateral Agents' rights with
respect thereto; and (vi) any other circumstance which might otherwise
constitute a defense available to, or a discharge of, the Pledgor, any
guarantor or any other person.

          7.13 Reasonable Care.  The Collateral Agent shall use its best
efforts to exercise reasonable care with respect to the Pledged Collateral in
its possession; provided, however, that the Collateral Agent shall be deemed
to have exercised reasonable care if such Collateral is accorded treatment
substantially comparable to that which the Collateral Agent accords its own
property or treatment substantially in accordance with actions requested by
Pledgor in writing.  It is agreed and understood that the Collateral Agent
shall have no responsibility for taking any necessary steps to preserve
rights against any Persons with respect to any Collateral.


<PAGE>

          7.14 Termination of Agreement; Release of Collateral.  Upon the
full and final indefeasible payment in full in cash and performance of the
Secured Obligations or upon a defeasance of the Securities in accordance with
the Indenture, this Agreement, and the covenants contained herein, shall
terminate (except for Article 1, Article 6 and Article 7 (other than Sections
7.12, 7.13 and 7.15)) and the Pledged Collateral shall be released by the
Collateral Agent to Pledgor and the Collateral Agent shall have no further
security interest in the Pledged Collateral.  In addition, this Agreement
shall terminate (other than Article 1, Article 6 and Article 7 (other than
Sections 7.12, 7.13 and 7.15)) and the Pledged Collateral shall be released
upon the prior written consent of the holders of at least 66 2/3% of the
aggregate principal amount of the Securities then outstanding (the "Requisite
Vote") pursuant to a request (a "Collateral Release Request") made by Pledgor
to the holders.  In the event that Pledgor does not receive the Requisite
Vote pursuant to any such Collateral Release Request, Pledgor may, at its
option, within five business days after the latest date on which such
consents are required to be delivered to Pledgor pursuant to the terms of the
Collateral Release Request, make an offer to purchase (a "Collateral Release
Repurchase Offer") all of the outstanding Securities at a purchase price of
101.5% of the Accreted Value thereof, plus accrued and unpaid interest, if
any, to the date of repurchase.  Upon the consummation of such Collateral
Release Repurchase Offer, this Agreement automatically shall terminate and
the Pledged Collateral shall be released.  If Pledgor shall at any time make
a Collateral Release Request, Pledgor shall pay to the voting holders an
amount in cash equal to .50% of the Accreted Value on such date as provided
in the Indenture.  Any Collateral Release Request shall be made as provided
in the Indenture.  Upon such termination, the Collateral Agent shall promptly
reassign and redeliver (or cause to be reassigned and redelivered) to
Pledgor, or to such person or persons as Pledgor shall designate or to
whomever may be lawfully entitled to receive such surplus, against receipt,
such of the Pledged Collateral (if any) as shall not have been sold or
otherwise applied by the Collateral Agent pursuant to the terms hereof and
shall still be held by it hereunder, together with appropriate instruments of
reassignment and release.  Any such reassignment shall be without recourse
upon or warranty by the Collateral Agent (other than a warranty that the
Collateral Agent has not assigned or delivered the Pledged Collateral so
reassigned and redelivered or its rights and interests hereunder to any other
person) and at the expense of Pledgor.

          In addition, in the event (a) that any Pledged Collateral is sold
and the Net Cash Proceeds thereof are applied in accordance with the terms of
Section 4.12 of the Indenture entitled "Disposition of Proceeds of Asset
Sales," (b) any Pledged Collateral is transferred to a subsidiary of Geotek
in accordance with Section 4.1.10 hereof, (c) Geotek sells Pledged Collateral
consisting of up to 75,000 shares of common stock of EGAC hereafter acquired
by it in conjunction with the exercise of options to purchase such common
stock to be issued to certain members of management of EGAC, or (d) any
Pledged Collateral is otherwise transferred in a transaction permitted by
this Agreement and the Indenture, the Collateral Agent shall release the
Liens in favor of the Collateral Agent in the Pledged Collateral so sold or
transferred; provided, that the Collateral Agent shall have received from
Geotek an Officers' Certificate and an Opinion of Counsel that such
Collateral has been sold or transferred in accordance with the terms hereof.
To the extent that any Pledged Collateral is sold and the Net Cash Proceeds
thereof are applied in accordance with the terms of Section 4.12 of the
Indenture, the Net Cash Proceeds resulting from the sale or other disposition
of such Pledged Collateral shall, to the extent permitted by law (including
any necessary FCC approval in regard to any radio licenses), be immediately
deposited in an account (the "Collateral Account") subject to a first
priority perfected Lien in favor of the Collateral Agent, and Pledgor shall
cause any non-cash proceeds from such sale or other disposition (including
securities) received by Pledgor or a subsidiary to immediately become subject
to a first priority perfected Lien in favor of the Collateral Agent.


<PAGE>


          Within 180 days after consummation of any sale or disposition of
Pledged Collateral, Pledgor shall apply 100.0% of the Net Cash Proceeds
resulting from such sale or disposition to (i) the purchase of Replacement
Assets, provided, that, when acquired, such Replacement Assets are subject to
a first priority perfected Lien in favor of the Collateral Agent, or (ii) the
acquisition or formation of a subsidiary, provided, that, when acquired or
formed, all of the outstanding Capital Stock of such subsidiary is subject to
a first priority perfected Lien in favor of the Collateral Agent; provided,
that if Pledgor does not apply such Net Cash Proceeds in accordance with
(i) or (ii) above, such Net Cash Proceeds shall remain in the Collateral
Account and not be released until the obligations of Pledgor under the
Indenture and the Securities have been discharged, this Agreement shall have
otherwise been terminated (other than Article 1, Article 6 and Article 7
(other than Sections 7.12, 7.13 and 7.15)) or until distributed to the
holders of the Securities as Excess Proceeds.  Subject to the proviso in the
preceding sentence, amounts in the Collateral Account shall be released
(i) upon the purchase of Replacement Assets, (ii) upon the acquisition or
formation of a subsidiary, all of whose Capital Stock has been pledged to the
Collateral Agent or (iii) when distributed to the holders of the Securities
as Excess Proceeds.

          7.15 Terms of this Agreement Control.  The parties hereto agree and
acknowledge that Article 4 of this Agreement contains certain covenants that
are more restrictive on Pledgor and its subsidiaries than certain of the
covenants contained in the Indenture.  The parties hereto agree that if any
provisions of this Agreement shall be more restrictive on Pledgor or conflict
with any provisions of the Indenture, then the provisions of this Agreement
shall be controlling, subject to, the termination of this Agreement pursuant
to Section 7.14 hereof.

          IN WITNESS WHEREOF, the Collateral Agent and the Pledgor have duly
executed this Agreement as of the day and year first above written.

          English law.

          legal process arising out of or connected with this Charge and service
          on NB3 (or such substitute) shall be deemed to be service on the
          Chargor.

    17.4  Submission to New York Courts and appointment of agent for service

          The parties hereto irrevocably consent to the jurisdiction of the
          courts of the State of New York and any federal court located in such

    18    Release of security

    18.1  The Collateral Agent undertakes to the Chargor that it will release
          the security hereby created:

          (a)  upon the full, final and indefeasible payment and discharge of
               the Secured Obligations, or

          (b)  if earlier, upon a defeasance of the Securities in accordance
               with the Indenture; or

          (c)  if earlier, upon the prior written consent of the Holders of at
               least 66 2/3% of the aggregate principal amount of the Securities
               then outstanding (the "Requisite Vote") pursuant to a request (a
               "Collateral Release Request") made by the Chargor to the Holders;
               or
<PAGE>

          (d)  if earlier, upon the consummation of a Collateral Release
               Repurchase Offer (as defined herein) in accordance with this
               clause 18.l(d). In the event that the Chargor does not receive
               the Requisite Vote pursuant to any such Collateral Release
               Request, the Charger may, at its option, within five business
               days after the latest date on which such consents are required to
               be delivered to the Charger pursuant to the terms of the
               Collateral Release Request, make an offer to purchase (a
               "Collateral Release Repurchase Offer") all of the outstanding
               Securities at a purchase price of 101.5% of the Accreted Value
               thereof, plus accrued and unpaid interest, if any, to the date of
               repurchase. If the Chargor shall at any time make a Collateral
               Release Request, the Chargor shall pay to the voting Holders an
               amount in cash equal to 0.50% of the Accreted Value on such date
               as provided in the Indenture. Any Collateral Release Request
               shall be made as provided in the Indenture.

          In order to effect any such release, the Collateral Agent shall, at
          the expense of the Chargor, promptly retransfer to such person as the
          Chargor shall nominate, the Shares remaining held by it and execute a
          deed of release in such form as the Charger shall reasonably request.
          The retransfer of the Shares to (or to the nominee of) the Chargor
          shall be without recourse to or warranty from the Collateral Agent
          (other than a warranty that the Collateral Agent has not assigned or
          delivered the Shares so retransferred to any other person).

    18.2  In addition, in the event that any of the Charged Property is sold and
          the Net Cash Proceeds thereof are applied in accordance with the terms
          of Section 4.12 of the Indenture entitled "Disposition of Proceeds of
          Asset Sales," or any of the Charged Property is otherwise transferred
          in a transaction permitted by the Indenture, the Collateral Agent
          shall release the security hereby created in favour of the Collateral
          Agent over the Charged Property so sold or transfered; provided, that
          the Collateral Agent shall have received from the Chargor an Officers'
          Certificate and an Opinion of Counsel that such Charged Property has
          been sold or transferred in accordance with the terms hereof. To the
          extent that any Charged Property is sold and the Net Cash Proceeds
          thereof are applied in accordance with the terms of Section 4.12 of
          the Indenture, the Net Cash Proceeds resulting from the sale or other
          disposition of such Charged Property shall, to the extent permitted by
          law (including any necessary approval in regard to any radio
          licenses), be immediately deposited in an account (the "Collateral
          Account") subject to a first priority perfected security interest in
          favour of a Collateral Agent, and the Chargor shall cause any non-cash
          proceeds from such sale or other disposition (including securities)
          received by the Chargor or a subsidiary to immediately become subject
          to a first priority perfected security interest in favour of the
          Collateral Agent.
<PAGE>

          Within 180 days after consummation of any sale or disposition of
          Charged Property, the Chargor shall apply 100.0% of the Net Cash
          Procceeds resulting from such sale or disposition to (i) the purchase
          of Replacement Assets, provided that, when acquired, such Replacement
          Assets are subject to a first priority perfected security interest in
          favour of the Collateral Agent, or (ii) the acquisition or formation
          of a subsidiary, provided, that, when acquired or formed, all of the
          outstanding Capital Stock or such subsidiary is subject to a first
          priority perfected security interest in favour of the Collateral
          Agent; provided that if the Chargor does not apply such Net Cash
          Proceeds in accordance with (i) or (ii) above, such Net Cash Proceeds
          shall remain in the Collateral Account and not be released until the
          obligations of the Chargor under the Indenture and the Securities have
          been discharged, the security hereby created shall otherwise have been
          released or until distributed to the Holders of the Securities as
          Excess Proceeds. Subject to the proviso in the preceding sentence,
          amounts in the Collateral Account shall be released (i) upon the
          purchase of Replacement Assets, (ii) upon the acquisition or formation
          of a subsidiary, all of whose Capital Stock has been pledged to the
          Collateral Agent or (iii) when distributed to the holders of the
          Seurities as Excess Proceeds.


IN WITNESS whereof this Charge has been executed and delivered as a deed by or
on behalf of the parties on the date stated at the begining of this Charge.

          WARRANT AGREEMENT (this "Agreement") dated as of June 30, 1995
between Geotek Communications, Inc., a Delaware corporation (the "Company"),
and IBJ Schroder Bank & Trust Company, a bank and trust company organized and
existing under the laws of the State of New York, as Warrant Agent (the
"Warrant Agent").

          WHEREAS, the Company has entered into a purchase agreement, dated
June 29, 1995, with Smith Barney Inc. (the "Initial Purchaser") pursuant to
which the Company has agreed to sell to the Initial Purchaser 207,000 Units
(the "Firm Units") consisting of $207,000,000 aggregate principal amount at
maturity of 15% Senior Secured Discount Notes due 2005 (the "Firm Notes") and
warrants (the "Firm Warrants") to purchase up to an aggregate of 6,210,000
shares of common stock, par value $.01 per share, of the Company (the "Common
Stock"), plus up to an additional 20,700 Units (the "Additional Units"),
consisting of $20,700,000 aggregate principal amount at maturity of 15%
Senior Secured Discount Notes due 2005 (the "Additional Notes") and warrants
to purchase up to an aggregate of 621,000 shares of Common Stock (the
"Additional Warrants"), issuable pursuant to the Initial Purchaser's option
to cover overallotments.  The Firm Notes and the Additional Notes are
hereinafter collectively referred to as the "Notes", the Firm Warrants and
the Additional Warrants are hereinafter collectively referred to as the
"Warrants" and the Firm Units and the Additional Units are hereinafter
collectively referred to as the "Units."  Each Warrant entitles the holder
thereof, upon exercise, to purchase one fully paid and nonassessable share of
Common Stock at an exercise price of $9.90 per share (the "Exercise Price").
The Exercise Price and the number of shares are both subject to adjustment
under certain circumstances as provided herein.  The shares of Common Stock
issuable upon exercise of the Warrants are referred to herein as "Warrant
Shares."  The Notes will be issued under an indenture to be dated as of June
30, 1995 (the "Indenture"; unless otherwise defined herein, defined terms
therein shall have the same meanings when used herein) between the Company
and IBJ Schroder Bank & Trust Company, as trustee (the "Trustee"); and

          WHEREAS, the Warrants shall bear the legend set forth in Exhibit A
attached hereto (the "Warrant Legend") and the Notes shall bear the legend
set forth in Exhibit A attached to the Indenture, in each case subject to the
terms of this Agreement and the Indenture, as the case may be.  Unless
registered under the Securities Act of 1933, as amended, and any applicable
state securities laws, the Warrant Shares shall initially bear the legend set
forth in Exhibit E (the "Warrant Shares Legend"); and

          WHEREAS, the Warrants and the Notes shall not be separately
transferable until the close of business upon the earliest to occur of (i)
January 6, 1996, (ii) the commencement of the Exchange Offer, (iii) such
earlier date as the Initial Purchaser may determine and specify to the
Warrant Agent in writing and (iv) in the event of a Change of Control, the

<PAGE>

date the Company mails notice thereof to the Holders of the Notes (the
"Separation Date"); and

          WHEREAS, the Company desires the Warrant Agent to act on behalf of
the Company, and the Warrant Agent is willing so to act, in connection with
the issuance of Warrant certificates and other matters as provided herein.

          NOW, THEREFORE, in consideration of the premises and the mutual
agreements herein set forth, the parties hereto agree as follows:

          SECTION 1.  Appointment of Warrant Agent.  The Company hereby
appoints the Warrant Agent to act as agent for the Company in accordance with
the instructions set forth hereinafter in this Agreement, and the Warrant
Agent hereby accepts such appointment.

          SECTION 2.  Issuance of Warrants.  Warrants shall be originally
issued in connection with the issuance of the Notes and shall not be
separately transferable from the Notes until on or after the Separation Date
as provided in Section 5 hereof.

          SECTION 3.  Warrant Certificates.  The Warrants shall be
substantially in the form annexed hereto as Exhibit A.

          Warrants offered and sold in reliance on Rule 144A shall be issued
initially in the form of a single permanent global Warrant in definitive,
fully registered form, substantially in the form set forth in Exhibit A (the
"U.S. Global Warrant"), deposited with the Warrant Agent, as custodian for
the Depository and registered in the name of a nominee of the Depository,
duly executed by the Company and countersigned by the Warrant Agent as
hereinafter provided.  The aggregate amount of the U.S. Global Warrant may
from time to time be increased or decreased by adjustments made on the
records of the Warrant Agent, as custodian for the Depository or its nominee,
as hereinafter provided.

          Warrants offered and sold in offshore transactions in reliance on
Regulation S shall be issued initially in the form of a single temporary
global Warrant in definitive, fully registered form substantially in the form
set forth in Exhibit A (the "Temporary Offshore Global Warrant") deposited
with the Warrant Agent, as custodian for the Depository and registered in the
name of a nominee of the Depository for the accounts of Euroclear and Cedel,
duly executed by the Company and countersigned by the Warrant Agent as
hereinafter provided.  At any time on or after August 15, 1995, upon receipt
by the Warrant Agent and the Company of a duly executed certificate
substantially in the form of Exhibit B hereto, a single permanent global
Warrant in definitive, fully registered form substantially in the form set
forth in Exhibit A, except that such Warrant shall not bear the legend (the
"Private Placement Legend") set forth in Section 5(b) hereof (the "Permanent
Offshore Global Warrant," and together with the Temporary Offshore Global
Warrant, the "Offshore Global Warrants"), duly executed by the Company and
countersigned by the Warrant Agent as hereinafter provided shall be deposited
with the Warrant Agent, as custodian for the Depository, and the Warrant
Agent shall reflect on its books and records the date and a decrease in the
aggregate amount of the Temporary Offshore Global Warrant in an amount equal

<PAGE>

to the aggregate amount of the beneficial interest in the Temporary Offshore
Global Warrant transferred.  The U.S. Global Warrant and the Offshore Global
Warrant are sometimes referred to herein individually as a "Global Warrant"
and collectively as the "Global Warrants."

          Warrants originally purchased by or transferred to Institutional
Accredited Investors which are not QIB's ("Non-Global Purchasers") shall be
issued in the form of permanent certificated Warrants in registered form in
substantially the form set forth in Exhibit A (the "Physical Warrants").
Upon the transfer of Physical Warrants by a Non-Global Purchaser either to a
QIB or in accordance with Regulation S, such Physical Warrants shall, unless
the relevant Global Warrant has previously been exchanged in whole for
Physical Warrants pursuant to Section 7(b)(ii), be exchanged for an interest
in such Global Warrant.

          SECTION 4.  Execution of Warrant Certificates.  Warrant
certificates shall be signed on behalf of the Company by its Chairman of the
Board, Chief Executive Officer, Chief Financial Officer, President or Senior
Vice President and Secretary or an Assistant Secretary.  Each such signature
upon the Warrant certificates may be in the form of a facsimile signature of
the present or any future Chairman of the Board, Chief Executive Officer,
Chief Financial Officer, President or Senior Vice President and Secretary or
Assistant Secretary and may be imprinted or otherwise reproduced on the
Warrant certificates and for that purpose the Company may adopt and use the
facsimile signature of any person who shall have been Chairman of the Board,
Chief Executive Officer, Chief Financial Officer, President, Senior Vice
President, Secretary or Assistant Secretary, notwithstanding the fact that at
the time the Warrant certificates shall be countersigned and delivered or
disposed of he or she shall have ceased to hold such office.  The seal of the
Company may be in the form of a facsimile thereof and may be impressed,
affixed, imprinted or otherwise reproduced on the Warrant certificates.

          In case any officer of the Company who shall have signed any of the
Warrant certificates shall cease to be such officer before the Warrant
certificates so signed shall have been countersigned by the Warrant Agent, or
disposed of by the Company, such Warrant certificates nevertheless may be
countersigned and delivered or disposed of as though such person had not
ceased to be such officer of the Company; and any Warrant certificate may be
signed on behalf of the Company by any person who, at the actual date of the
execution of such Warrant certificate, shall be a proper officer of the
Company to sign such Warrant certificate, although at the date of the
execution of this Agreement any such person was not such officer.

          Warrant certificates shall be dated the date of countersignature by
the Warrant Agent.

          SECTION 5.  Transfers of Warrants.

          (a)  Prior to the Separation of Warrants and Notes; Separation of
Warrants and Notes.  Notwithstanding the provisions of Section 7 hereof, on


<PAGE>

or after the Separation Date, the registered holder of a Warrant certificate
containing a Warrant Legend may surrender such Warrant certificate
accompanied by a written instrument or instruments of transfer in form
satisfactory to the Warrant Agent, duly executed by the registered holder or
holders thereof or by the duly appointed legal representative thereof or by a
duly authorized attorney to the Warrant Agent, at its corporate trust office
in the City of New York, State of New York (the "Warrant Agent Office") for
the exchange of such Warrant containing a Warrant Legend, in whole or in
part, for a new Warrant certificate or certificates not containing the first
paragraph of the Warrant Legend (such surrender and exchange being referred
to herein as a "Separation" and the related Warrants being referred to as
"Separated").

          Until the Separation Date, no Warrant may be sold, assigned or

the Warrant Agent receives confirmation from the Trustee for the Notes that

     REQUESTED BY THE COMPANY, HAS DELIVERED TO THE COMPANY AN OPINION OF
     COUNSEL TO SUCH EFFECT.

          (b)  Restrictive Legend. Except as otherwise provided in Section
7(c)(vi) hereof, the U.S. Global Warrant, the Temporary Offshore Global
Warrant and any Physical Warrant issued in exchange for interests therein
shall bear the following legend:

THIS SECURITY HAS NOT BEEN REGISTERED UNDER THE U.S SECURITIES ACT OF 1933,
AS AMENDED (THE "SECURITIES ACT"), AND, ACCORDINGLY, MAY NOT BE OFFERED OR
SOLD WITHIN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF U.S.
PERSONS EXCEPT AS SET FORTH IN THE FOLLOWING SENTENCE.  BY ITS ACQUISITION
HEREOF, THE HOLDER (1) REPRESENTS THAT (A) IT IS A "QUALIFIED INSTITUTIONAL
BUYER" (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) OR (B) IT IS AN
INSTITUTIONAL "ACCREDITED INVESTOR" (AS DEFINED IN RULE 501(a)(1), (2), (3)
OR (7) OF REGULATION D UNDER THE SECURITIES ACT) (AN "INSTITUTIONAL
ACCREDITED INVESTOR") OR (C) IT IS NOT A U.S. PERSON AND IS ACQUIRING THIS
SECURITY IN AN OFFSHORE TRANSACTION IN COMPLIANCE WITH REGULATION S UNDER THE
SECURITIES ACT, (2) AGREES THAT IT WILL NOT, WITHIN THREE YEARS AFTER THE
LATER OF THE ORIGINAL ISSUANCE OF THIS SECURITY OR THE LAST DATE ON WHICH
THIS SECURITY WAS HELD BY THE COMPANY OR ANY AFFILIATE OF THE COMPANY, RESELL
OR OTHERWISE TRANSFER THIS SECURITY EXCEPT (A) TO THE COMPANY OR ANY
SUBSIDIARY THEREOF, (B) INSIDE THE UNITED STATES TO A QUALIFIED INSTITUTIONAL
BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, (C) INSIDE THE
UNITED STATES TO AN INSTITUTIONAL ACCREDITED INVESTOR THAT, PRIOR TO SUCH

OFFSHORE TRANSACTION IN COMPLIANCE WITH RULE 904 UNDER THE SECURITIES ACT,
(E) PURSUANT TO THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER

SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND.  IN CONNECTION WITH ANY TRANSFER
OF THIS SECURITY WITHIN THREE YEARS AFTER THE LATER OF THE ORIGINAL ISSUANCE
OF THE SECURITY OR THE LAST DATE ON WHICH THIS SECURITY WAS HELD BY THE
COMPANY OR AN AFFILIATE OF THE COMPANY, THE HOLDER MUST CHECK THE APPROPRIATE
BOX SET FORTH ON THE REVERSE HEREOF RELATING TO THE MANNER OF SUCH TRANSFER


<PAGE>

AND SUBMIT THIS CERTIFICATE TO THE WARRANT AGENT.  IF THE PROPOSED TRANSFEREE
IS AN INSTITUTIONAL ACCREDITED INVESTOR, THE HOLDER MUST, PRIOR TO SUCH
TRANSFER, FURNISH TO THE WARRANT AGENT AND THE COMPANY SUCH CERTIFICATIONS,
LEGAL OPINIONS OR OTHER INFORMATION AS EITHER OF THEM MAY REASONABLY REQUIRE
TO CONFIRM THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR
IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE
SECURITIES ACT. AS USED HEREIN, THE TERMS "OFFSHORE TRANSACTION," "UNITED
STATES" AND "U.S. PERSON" HAVE THE MEANINGS GIVEN TO THEM BY REGULATION S
UNDER THE SECURITIES ACT.  THE WARRANT AGREEMENT CONTAINS A PROVISION
REQUIRING THE WARRANT AGENT TO REFUSE TO REGISTER ANY TRANSFER OF THIS
SECURITY IN VIOLATION OF THE FOREGOING RESTRICTIONS.

          (c)  Global Warrant Legend.  Each Global Warrant shall also bear
the following legend:

UNLESS THIS WARRANT IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE
DEPOSITORY TRUST COMPANY TO THE COMPANY OR ITS AGENT FOR REGISTRATION OF
TRANSFER, EXCHANGE OR PAYMENT, AND ANY WARRANT ISSUED IS REGISTERED IN THE
NAME OF CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED
REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY OR SUCH OTHER REPRESENTATIVE
OF THE DEPOSITORY TRUST COMPANY OR SUCH OTHER NAME AS IS REQUESTED BY AN
AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY (AND ANY PAYMENT
HEREON IS MADE TO CEDE & CO. OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN
AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY), ANY TRANSFER,
PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS
WRONGFUL SINCE THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST
HEREIN.

TRANSFERS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS IN WHOLE, BUT
NOT IN PART, TO NOMINEES OF CEDE & CO. OR TO A SUCCESSOR THEREOF OR SUCH
SUCCESSOR'S NOMINEE AND TRANSFERS OF PORTIONS OF THIS GLOBAL SECURITY SHALL
BE LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE RESTRICTIONS SET FORTH IN
SECTION 7(c) OF THE WARRANT AGREEMENT.

          SECTION 6.  Registration and Countersignature.  The Warrant Agent,
on behalf of the Company, shall number and register the Warrant certificates
in a register as they are issued by the Company.

          Warrant certificates shall be manually countersigned by the Warrant
Agent and shall not be valid for any purpose unless so countersigned.  The
Warrant Agent shall, upon written instructions of the Chairman of the Board,
Chief Executive Officer, Chief Financial Officer, President, a Senior Vice
President or Secretary of the Company, initially countersign and deliver
Warrants entitling the holders thereof to purchase not more than the number
of Warrant Shares referred to above in the first recital hereof and shall
countersign and deliver Warrants as otherwise provided in this Agreement.

          The Company and the Warrant Agent may deem and treat the registered
holder(s) of the Warrant certificates as the absolute owner(s) thereof


<PAGE>

(notwithstanding any notation of ownership or other writing thereon made by
anyone), for all purposes, and neither the Company nor the Warrant Agent
shall be affected by any notice to the contrary.  The Company agrees to
arrange for the Trustee under the Indenture (or any other Registrar
thereunder) to act as registrar hereunder with respect to Warrants that are
not Separated.

          SECTION 7.  (a)  Registration of Transfers and Exchanges.  In
accordance with this Section 7, the Warrant Agent shall from time to time
register the transfer of any outstanding Warrant certificates upon the
records to be maintained by it for that purpose, upon surrender thereof
accompanied by a written instrument or instruments of transfer in form
satisfactory to the Warrant Agent, duly executed by the registered holder or
holders thereof or by the duly appointed legal representative thereof or by a
duly authorized attorney.  Upon any such registration of transfer, a new
Warrant certificate shall be issued to the transferee(s) and the surrendered
Warrant certificate shall be canceled by the Warrant Agent.  Canceled Warrant
certificates shall thereafter be disposed of by the Warrant Agent in a manner
consistent with the Warrant Agent's customary procedure and in accordance
with applicable law.

          Warrant certificates may be exchanged at the option of the
holder(s) thereof, when surrendered to the Warrant Agent at its office for
another Warrant certificate or other Warrant certificates of like tenor and
representing in the aggregate a like number of Warrants.  Warrant
certificates surrendered for exchange shall be canceled by the Warrant Agent.
Such canceled Warrant certificates shall then be disposed of by the Warrant
Agent in a manner consistent with the Warrant Agent's customary procedure and
in accordance with applicable law.

          No service charge shall be made for any transfer or exchange of
Warrant certificates or any issuance of Warrant certificates in connection
with a Separation, but the Company may require payment of a sum sufficient to
cover any stamp or other governmental charge or tax that may be imposed in
connection with any such transfer or exchange.

          The Warrant Agent is hereby authorized to countersign, in
accordance with the provisions of this Section 7 and Section 5, the new
Warrant certificates required pursuant to the provisions of this Section 7.

          (b)  Book-Entry Provisions for the Global Warrants.  (i) The Global
Warrants initially shall (x) be registered in the name of the Depository or
the nominee of such Depository, (y) be delivered to the Warrant Agent as
custodian for the Depository and (z) bear legends as set forth in Section
5(b).

          (ii)  Transfers of any Global Warrant shall be limited to transfers
of such Global Warrant in whole, but not in part, to the Depository, its
successors or their respective nominees.  Beneficial interests in any Global
Warrant may be transferred in accordance with the applicable rules and
procedures of the Depository and, if applicable, Euroclear and Cedel and the
provisions of Section 7(c).  If, for any reason, a beneficial owner requires


<PAGE>

physical delivery of a Physical Warrant, such beneficial owner shall transfer
its interest in the Global Warrant in exchange for Physical Warrants in
accordance with the applicable rules and procedures of the Depository and, if
applicable, Euroclear and Cedel and the provisions of Section 7(c).  In
addition, Physical Warrants shall be transferred to all beneficial owners in
exchange for their beneficial interests in any Global Warrant if (x) the
Depository notifies the Company that it is unwilling or unable to continue as
Depository for such Global Warrant, and a successor depository is not
appointed by the Company within 90 days of such notice or (y) an Event of
Default has occurred and is continuing and the Warrant Agent has received a
request from the Depository.

          (iii)  Any beneficial interest in one of the Global Warrants that
is transferred to a person who takes delivery in the form of an interest in
the other Global Warrant will, upon transfer, cease to be an interest in such
Global Warrant and become an interest in the other Global Warrant and,
accordingly, will thereafter be subject to all transfer restrictions, if any,
and other procedures applicable to beneficial interests in such other Global
Warrant for as long as it remains such an interest.

          (iv)  In connection with any transfer of a beneficial interest in
any Global Warrant to a transferee receiving Physical Warrants pursuant to
paragraph (b)(ii) of this Section 7, the Warrant Agent shall reflect on its
books and records the date and a decrease in the aggregate amount of such
Global Warrant in an amount equal to the aggregate amount of the beneficial
interest in such Global Warrant to be transferred, and the Company shall
execute, and the Warrant Agent shall countersign and deliver, one or more
Physical Warrants of like tenor and amount.

          (v)  In connection with the transfer of an entire Global Warrant to
beneficial owners pursuant to paragraph (b)(ii) of this Section 7, such
Global Warrant shall be deemed to be surrendered to the Warrant Agent for
cancellation, and the Company shall execute, and the Warrant Agent shall
countersign and deliver, to each beneficial owner identified by the
Depository in exchange for its beneficial interest in such Global Warrant, an
equal aggregate amount of Physical Warrants of authorized denominations.

          (vi)  Any Physical Warrant delivered in exchange for an interest in
the U.S. Global Warrant or the Temporary Offshore Global Warrant pursuant to
paragraphs (b)(ii), b)(iv) or (b)(v) of this Section 7 shall, except as
otherwise provided by paragraph (c)(vi) of this Section 7, bear the legends
regarding transfer restrictions applicable to the Physical Warrant set forth
in Sections 5(a) and 5(b).

          (vii)  The registered holder of a Global Warrant may grant proxies
and otherwise authorize any person, including Agent Members and persons that
may hold interests through Agent Members, to take any action which a Warrant
holder is entitled to take under this Warrant Agreement or the Warrants.

                given in accordance with the Depository's and the Warrant
                Agent's procedures, the Warrant Agent shall reflect on its
                books and records the date and a decrease in the aggregate
                amount of the Global Warrant in an amount equal to the
                aggregate amount of the beneficial interest in the Global

                Warrants or an interest in the Temporary Offshore Global
                Warrant, the Warrant Agent shall register the transfer if
                such transfer is being made by a proposed transferor who has
                checked the box provided for on the form of Warrant stating,

                certification provided for on the form of Warrant stating, or
                has otherwise advised the Company and the Warrant Agent in
                writing, that it is purchasing the Warrant for its own


<PAGE>

                account or an account with respect to which it exercises sole
                investment discretion and that it and any such account is a
                QIB within the meaning of Rule 144A, and is aware that the
                sale to it is being made in reliance on Rule 144A and
                acknowledges that it has received such information regarding
                the Company as it has requested pursuant to Rule 144A or has
                determined not to request such information and that it is
                aware that the transferor is relying upon its foregoing
                representations in order to claim the exemption from
                registration provided by Rule 144A.

           (y)  If the proposed transferee is an Agent Member and the Warrant
                to be transferred consists of Physical Warrants or an
                interest in the Temporary Offshore Global Warrant, upon

                receipt of a certificate substantially in the form of Exhibit
                D hereto from the proposed transferor.

           (y)  On and after August 15, 1995, the Warrant Agent shall
                register any proposed transfer to any Non-U.S. Person if the
                Warrant to be transferred is an interest in the U.S. Global
                Warrant, upon receipt of a certificate substantially in the
                form of Exhibit D from the proposed transferor.

           (z)  (A) If the proposed transferor is an Agent Member holding a

<PAGE>

                Warrant Agent shall reflect on its books and records the date
                and a decrease in the aggregate amount of the U.S. Global
                Warrant in an amount equal to the aggregate amount of the

                Agent's procedures, the Warrant Agent shall reflect on its
                books and records the date and an increase in the aggregate

     Placement Legend.  Upon the transfer, exchange or replacement of
     Warrants bearing the Private Placement Legend, the Warrant Agent shall
     deliver only Warrants that bear the Private Placement Legend unless
     either (x) the circumstances contemplated by the third paragraph of
     Section 3 or paragraph (c)(i)(x)(A) or (c)(v)(y) of this Section 7 exist
     or (y) there is delivered to the Warrant Agent an opinion of counsel
     reasonably satisfactory to the Company and the Warrant Agent to the
     effect that neither such legend nor the related restrictions on transfer
     are required in order to maintain compliance with the provisions of the
     Securities Act.

               (vii)  General.  The provisions hereof shall be qualified in
     their entirety by any applicable securities laws of the United States
     and any other applicable jurisdiction and by the procedures of any
     applicable clearing agency, in each case as in effect from time to time,
     and all such laws and clearing procedures shall be deemed to be
     incorporated herein by reference.  By its acceptance of any Warrant
     bearing the Private Placement Legend, each holder of such a Warrant
     shall be deemed to acknowledge the restrictions on transfer of such
     Warrant set forth in this Warrant Agreement and in the Private Placement
     Legend and agrees that it will transfer such Warrant only as provided in
     this Warrant Agreement.  The Warrant Agent shall not register a transfer
     of any Warrant unless such transfer complies with the restrictions on
     transfer of such Warrant set forth in this Warrant Agreement.  In
     connection with any transfer of Warrants, each Warrant holder agrees by
     its acceptance of the Warrants to furnish the Warrant Agent or the
     Company such certifications, legal opinions or other information as
     either of them may reasonably require to confirm that such transfer is
     being made pursuant to an exemption from, or a transaction not subject

<PAGE>


     to, the registration requirements of the Securities Act; provided that
     the Warrant Agent shall not be required to determine (but may rely on a
     determination made by the Company with respect to) the sufficiency of
     any such certifications, legal opinions or other information.

          SECTION 8.  Terms of Warrants; Exercise of Warrants.  Subject to
the terms of this Agreement, each Warrant holder shall have the right, which
may be exercised at any time on or after 9:00 a.m., New York, New York time
on January 6, 1996 until 5:00 p.m., New York, New York time on July 15, 2005
(the "Expiration Date") to exercise each Warrant and receive from the Company
the number of fully paid and nonassessable Warrant Shares which the holder
may at the time be entitled to receive on exercise of such Warrants and
payment of the Exercise Price (as herein defined) then in effect for such
Warrant Shares; provided that no Warrant holder shall be entitled to exercise
such holder's Warrants at any time unless, at the time of exercise, (i) a
registration statement under the Securities Act covering the offer and sale
of the Warrant Shares has been filed with, and declared effective by, the
Securities and Exchange Commission (the "SEC"), and no stop order suspending
the effectiveness of such registration statement has been issued by the SEC
or (ii) the offer and sale of the Warrant Shares to the Warrant holder are
exempt from registration under the Securities Act and the holder of the
Warrants, if so requested by the Company, has delivered to the Company an
opinion of counsel to such effect.  Each Warrant, when exercised, will
entitle the holder thereof to purchase one fully paid and nonassessable share
of Common Stock at the Exercise Price.  The Exercise Price and the number of
shares are both subject to adjustment under certain circumstances as provided
herein.  Each Warrant not exercised prior to the Expiration Date shall become
void and all rights thereunder and all rights in respect thereof under this
Agreement shall cease as of such time.

          A Warrant may be exercised at any time on or after January 6, 1996
upon surrender to the Company at the principal office of the Warrant Agent of
the certificate or certificates evidencing the Warrants to be exercised with
the form of election to purchase on the reverse thereof duly filled in and
signed, which signature shall be guaranteed by an "eligible guarantor" as
defined in the regulations promulgated under the Securities Exchange Act of
1934, as amended (the "Exchange Act"), and upon payment to the Warrant Agent
for the account of the Company of the Exercise Price, as adjusted as herein
provided, for each Warrant then exercised.  Payment of the aggregate Exercise
Price shall be made in the form of cash or a certified or official bank check
payable to the order of the Company.

          Subject to the provisions of Section 9 hereof, upon such surrender
of Warrants and payment of the Exercise Price, the Company shall issue and
cause to be delivered with all reasonable dispatch to or upon the written
order of the holder and in such name or names as the Warrant holder may



<PAGE>

designate, a certificate or certificates for the number of whole Warrant
Shares issuable upon the exercise of such Warrants together with any cash
which may be payable as provided in Section 17 hereof; provided that if any
consolidation, merger or lease or sale of assets is proposed to be effected
by the Company as described in subsection (l) of Section 15 hereof, or a
tender offer or an exchange offer for shares of Common Stock of the Company
shall be made, upon such surrender of Warrants and payment of the Exercise
Price as aforesaid, the Company shall, as soon as possible, but in any event
not later than two Business Days thereafter, issue and cause to be delivered
to the registered holder thereof or any person so designated to be named
therein the full number of Warrant Shares issuable upon the exercise of such
Warrants in the manner described in this sentence together with any cash
which may be payable as provided in Section 17 hereof.  Such certificate or
certificates shall be deemed to have been issued and any person so designated
to be named therein shall be deemed to have become a holder of record of such
Warrant Shares as of the date of the surrender of such Warrants and payment
of the aggregate Exercise Price.  No fractional shares shall be issued upon
exercise of any Warrants in accordance with Section 17 hereof.

          The Warrants shall be exercisable at any time on or after January
6, 1996, at the election of the holders thereof, either in full or from time
to time in part (in whole shares) and, in the event that a certificate
evidencing Warrants is exercised in respect of fewer than all of the Warrant
Shares issuable on such exercise at any time prior to the date of expiration
of the Warrants, a new certificate evidencing the remaining Warrant or
Warrants will be issued, and the Warrant Agent is hereby irrevocably
authorized to countersign and to deliver the required new Warrant certificate
or certificates pursuant to the provisions of this Section and of Section 4
hereof, and the Company, whenever required by the Warrant Agent, will supply
the Warrant Agent with Warrant certificates duly executed on behalf of the
Company for such purpose.

          All Warrant certificates surrendered upon exercise of Warrants
shall be canceled by the Warrant Agent.  Such canceled Warrant certificates
shall then be disposed of by the Company in accordance with applicable law.
The Warrant Agent shall account promptly to the Company with respect to
Warrants exercised and concurrently pay to the Company all monies received by
the Warrant Agent for the purchase of the Warrant Shares through the exercise
of such Warrants.

          The Warrant Agent shall keep copies of this Agreement and any
notices given or received hereunder available for inspection by the holders
during normal business hours at its office.  The Company shall supply the
Warrant Agent from time to time with such numbers of copies of this Agreement
as the Warrant Agent may request.

          SECTION 9.  Reports.  So long as any of the Warrants remain
outstanding, the Company shall cause copies of all quarterly and annual
financial reports and of the information, documents and other reports (or


<PAGE>

copies of such portions of any of the foregoing as the SEC may by rules and
regulations prescribe) that the Company is required to file with the SEC
pursuant to Section 13 or 15(d) of the Exchange Act ("SEC Reports") to be
filed with the Warrant Agent and mailed to the holders of Warrants, in each
case, within 15 days after filing with the SEC.  If the Company is not
subject to the requirements of Section 13 or 15(d) of the Exchange Act, the
Company shall nevertheless continue to cause SEC Reports, comparable to those
that it would be required to file pursuant to Section 13 or 15(d) of the
Exchange Act if it were then subject to the requirements of either such
Section, to be so filed with the SEC for public availability (unless the SEC
will not accept such a filing) and with the Warrant Agent and mailed to the
holders of Warrants, in each case, within the same time periods as would have
applied (including under the preceding sentence) had the Company then been
subject to the requirements of Section 13 or 15(d) of the Exchange Act.  The
Company shall make available to investors and prospective investors of the
Warrants information that satisfies the requirements of Rule 144A(d)(4) under
the Securities Act.

          SECTION 10.  Payment of Taxes.  No service charge shall be made to
any holder of a Warrant for any exercise, exchange or registration of
transfer of Warrant certificates, and the Company will pay all documentary
stamp taxes attributable to the initial issuance of Warrant Shares upon the
exercise of Warrants or to any Separation; provided that the Company shall
not be required to pay any tax or taxes which may be payable in respect of
any transfer involved in the issue of any Warrant certificates or any
certificates for Warrant Shares in a name other than that of the registered
holder of a Warrant certificate surrendered upon the exercise of a Warrant,
and the Company shall not be required to issue or deliver such Warrant
certificates unless or until the person or persons requesting the issuance
thereof shall have paid to the Company the amount of such tax or shall have
established to the satisfaction of the Company that such tax has been paid.

          SECTION 11.  Mutilated or Missing Warrant Certificates.  If any of
the Warrant certificates shall be mutilated, lost, stolen or destroyed, the
Company may in its discretion issue and the Warrant Agent may countersign, in
exchange and substitution for and upon cancellation of the mutilated Warrant
certificate, or in lieu of and substitution for the Warrant certificate lost,
stolen or destroyed, a new Warrant certificate of like tenor and representing
an equivalent number of Warrants, but only upon receipt of evidence
satisfactory to the Company and the Warrant Agent of such loss, theft or
destruction of such Warrant certificate and indemnity and security therefor,
if requested, also satisfactory to them.  Applicants for such substitute
Warrant certificates shall also comply with such other reasonable regulations
and pay such other reasonable charges as the Company or the Warrant Agent may
prescribe.

          SECTION 12.  Reservation of Warrant Shares.  The Company will at

<PAGE>

all times reserve and keep available, free of preemptive rights and free from
all taxes, liens, charges and security interests with respect to the issuance
thereof, out of the aggregate of its authorized but unissued Common Stock,
for the purpose of enabling it to satisfy any obligation to issue Warrant
Shares upon exercise of Warrants, the maximum number of shares of Common
Stock which may then be deliverable upon the exercise of all outstanding
Warrants.

          The Company or the transfer agent for the Common Stock (the
"Transfer Agent") and every subsequent transfer agent for any shares of the
Company's capital stock issuable upon the exercise of any of the rights of
purchase aforesaid will be irrevocably authorized and directed at all times
to reserve such number of authorized shares as shall be required for such
purpose.  The Company will keep a copy of this Agreement on file with the
Transfer Agent and with every subsequent transfer agent for any shares of the
Company's capital stock issuable upon the exercise of the rights of purchase
represented by the Warrants.  The Warrant Agent is hereby irrevocably
authorized to requisition from time to time from such Transfer Agent the
stock certificates required to honor outstanding Warrants upon exercise
thereof in accordance with the terms of this Agreement.  The Company will
supply such Transfer Agent with duly executed certificates for such purposes
and will provide or otherwise make available to the Warrant Agent any cash
which may be payable as provided in Section 17 hereof.  The Company will
furnish such Transfer Agent a copy of all notices of adjustments and
certificates related thereto transmitted to each holder pursuant to Section
18 hereof.

          Before taking any action which would cause an adjustment pursuant
to Section 15 hereof to reduce the Exercise Price below the then par value
(if any) of the Warrant Shares, the Company will take all corporate action
necessary, in the opinion of its counsel (which may be counsel employed by
the Company), in order that the Company may validly and legally issue fully
paid and nonassessable Warrant Shares at the Exercise Price as so adjusted.

          The Company covenants that all Warrant Shares which may be issued
upon exercise of Warrants will be, upon payment of the Exercise Price and
issuance thereof, duly and validly issued, fully paid, nonassessable, free of
preemptive rights and free from all taxes, liens, charges and security
interests with respect to the issuance thereof.

          SECTION 13.  Obtaining Stock Exchange Listings.  The Company shall
from time to time take all action necessary so that the Warrant Shares,
immediately upon their issuance upon the exercise of Warrants, will be listed
on the principal securities exchanges, interdealer quotation systems and
markets, if any, on which other shares of Common Stock are then listed or
quoted.

          SECTION 14.  Repurchase.  For purposes of this Section 14, a
"Repurchase Event" is defined to occur on any date prior to July 15, 2005
when the Company consolidates with, merges into or with (but only where
holders of the Common Stock receive consideration in exchange for all or part

<PAGE>


of such shares of Common Stock) or sells all or substantially all of its
assets to, another person which does not have a class of equity securities
registered under the Exchange Act or a wholly-owned subsidiary of such
person, if the consideration for such transaction does not consist solely of
cash or such merger or consolidation is not effected solely for the purpose
of changing the Company's state of incorporation.

          An "Independent Financial Expert" is a firm (a) which does not, and
whose directors, officers and employees or Affiliates do not, have a direct
or indirect financial interest in the Company and (b) which, in the judgment
of the Board of Directors, is otherwise independent and qualified to perform
the task for which it is to be engaged.

          Following the occurrence of a Repurchase Event, the Company shall
be obligated to make an offer to holders of all outstanding Warrants to
repurchase for cash all outstanding Warrants (a "Repurchase Offer").  Until
5:00 p.m. (New York City time) on the final surrender date selected by the
Company (which such date shall be at least 60 but not more than 120 calendar
days following the date on which the Company gives notice of such Repurchase
Offer) (the "Final Surrender Time"), the holders of Warrants may surrender
all or part of their Warrants for repurchase by the Company.  Warrants
received by the Warrant Agent in proper form for purchase during a Repurchase
Offer prior to the Final Surrender Time are to be repurchased by the Company
at a price in cash (the "Repurchase Price") equal to the value (the "Relevant
Value") on the date which is five business days prior to the date notice of
such Repurchase Offer is given (the "Valuation Date") of the Common Stock
issuable, and other securities which would have been delivered, upon exercise
of the Warrants had the Warrants been exercised, less the Exercise Price
therefor (regardless of whether the Warrants are then exercisable).  The
Relevant Value of the Common Stock and other securities, assuming exercise of
all Warrants, on any Valuation Date shall be (i) if the Common Stock (or
other securities) is registered under the Exchange Act, the average of the
closing sales prices of the Common Stock (or other securities) for the 20
consecutive trading days immediately preceding such Valuation Date or, if the
Common Stock (or other securities) has been registered under the Exchange Act
for less then 20 consecutive trading days before such date, then the average
of the closing sales prices for all of the trading days before such date for
which closing sales prices are available or (ii) if the Common Stock (or
other securities) is not registered under the Exchange Act or if the value
cannot be computed under clause (i) above, the value determined (without
giving effect to any discount for lack of liquidity, the fact that the
Company has no class of equity securities registered under the Exchange Act
or the fact that the shares of Common Stock and other securities issuable
upon exercise of the Warrants represent a minority interest in the Company)
by an Independent Financial Expert.

<PAGE>


          If the value of the Common Stock (or other securities) is
determined in the manner described in clause (ii) of the preceding paragraph,
the Board of Directors of the Company shall select an Independent Financial
Expert not more than five business days following any Repurchase Event.
Within two business days after its selection of the Independent Financial
Expert, the Company must deliver to the Warrant Agent a notice setting forth
the name of such Independent Financial Expert.  The Company also must cause
the Independent Financial Expert to deliver to the Company, with a copy to
the Warrant Agent, a value report (the "Value Report") which states the
Relevant Value of the Common Stock and other securities or property of the
Company, if any, being valued as of the Valuation Date and contains a brief
statement as to the nature and scope of the examination or investigation upon
which the determination was made.  The Warrant Agent shall have no duty with
respect to the Value Report of any Independent Financial Expert, except that
the Warrant Agent shall keep such Value Report on file and available for
inspection, during normal business hours, by the holders of the Warrants.  In
the absence of manifest error, the determination of the Independent Financial
Expert as to Relevant Value shall be conclusive as to all persons.

          SECTION 15.  Adjustment of Exercise Price and Number of Warrant
Shares Issuable.  The Exercise Price and the number of Warrant Shares
issuable upon the exercise of each Warrant are subject to adjustment from
time to time upon the occurrence of the events enumerated in this Section 15.
For purposes of this Section 15, "Common Stock" means the Common Stock and
any other stock of the Company, however designated, for which the Warrants
may be exercisable.

          (a)  Adjustment for Change in Capital Stock.

          If the Company:

               (1)  pays a dividend or makes a distribution on its Common
     Stock in shares of its Common Stock;

               (2)  subdivides its outstanding shares of Common Stock into a
     greater number of shares;

               (3)  combines its outstanding shares of Common Stock into a
     smaller number of shares;

               (4)  makes a distribution on its Common Stock in shares of its
     capital stock other than Common Stock; or

               (5)  issues by reclassification of its Common Stock any shares
     of its capital stock,  then the Exercise Price and the number and kind of 
shares of capital stock of the Company issuable upon the exercise of a Warrant
(as in effect immediately prior to such action) shall be proportionately
adjusted so that the holder of any Warrant thereafter exercised may receive the
aggregate number and kind of shares of capital stock of the Company which he
would have owned immediately following such action if such Warrant had been
exercised immediately prior to such action.

          The adjustment shall become effective immediately after the record
date, subject to subsection (p) of this Section 15, in the case of a dividend

<PAGE>

or distribution and immediately after the effective date in the case of a
subdivision, combination or reclassification.

          If after an adjustment a holder of a Warrant upon exercise of it
may receive shares of two or more classes or series of capital stock of the
Company, the Company shall determine the allocation of the adjusted Exercise
Price between the classes or series of capital stock.  After such allocation,
the exercise privilege and the Exercise Price of each class or series of
capital stock shall thereafter be subject to adjustment on terms comparable
to those applicable to Common Stock in this Section 15.

          Such adjustment shall be made successively whenever any event
listed above shall occur.

          (b)  Adjustment for Rights Issue.

          If the Company distributes any rights, options or warrants to all
holders of its Common Stock entitling them for a period expiring within 60
days after the record date mentioned below to purchase shares of Common Stock
or securities convertible into or exchangeable for shares of Common Stock at
a price per share less than the current market price per share on that record
date, the Exercise Price shall be adjusted in accordance with the following
formula:

                       O + N  x  P
                           -------
          E'  =  E  x        M   
                       -----------   
                         O  +  N

          where:

          E' = the adjusted Exercise Price.

          E =  the current Exercise Price.

          O =  the number of shares of Common Stock outstanding on the record
               date.

          N =  the number of additional shares of Common Stock offered.

          P =  the offering price per share of the additional shares.

          M =  the current market price per share of Common Stock on the
               record date.

          The adjustment shall be made successively whenever any such rights,
options or warrants are issued and shall become effective immediately after
the record date for the determination of stockholders entitled to receive the
rights, options or warrants.  If at the end of the period during which such
rights, options or warrants are exercisable, not all rights, options or
warrants shall have been exercised, the Exercise Price shall be immediately
readjusted to what it would have been if "N" in the above formula had been
the number of shares actually issued.

          (c)  Adjustment for Other Distributions.

          If the Company distributes to all holders of its Common Stock any
of its assets or debt securities or any rights or warrants to purchase debt
securities, assets or other securities of the Company, the Exercise Price
shall be adjusted in accordance with the following formula:

          E'  =  E  x  M - F
                       -----
                         M
          where:


<PAGE>


          E' = the adjusted Exercise Price.

          E =  the current Exercise Price.

          M =  the current market price per share of Common Stock on the
               record date mentioned in the immediately succeeding paragraph.

          F =  the fair market value on the record date of the assets,
               securities, rights or warrants applicable to one share of
               Common Stock.  The Board of Directors shall determine the fair
               market value.

          The adjustment shall be made successively whenever any such
distribution is made and shall become effective immediately after the record
date for the determination of stockholders entitled to receive the
distribution.

          This subsection (c) does not apply to:

          (1) rights, options or warrants referred to in subsection (b) of
this Section 15, or

          (2) cash dividends or cash distributions paid out of consolidated
current or retained earnings as shown on the books of the Company prepared in
accordance with generally accepted accounting principles other than any
Extraordinary Cash Dividend (as defined below).  An "Extraordinary Cash
Dividend" shall be that portion, if any, of the aggregate amount of all cash
dividends paid in any fiscal year which exceeds $25 million.  In all cases,
the Company shall give the Warrant holders at least 30 days notice of a
record date for any dividend payment on its Common Stock.

          (d)  Adjustment for Common Stock Issue.

          If the Company issues shares of Common Stock for a consideration
per share less than the current market price per share on the date the
Company fixes the offering price of such additional shares, the Exercise
Price shall be adjusted in accordance with the formula:

                            P
                            -
          E'  =  E  x   O + M
                        -----
                          A

          where:

          E' = the adjusted Exercise Price.

          E =  the then current Exercise Price.

          O =  the number of shares outstanding immediately prior to the
               issuance of such additional shares.

          P =  the aggregate consideration received for the issuance of such
               additional shares.

          M =  the current market price per share on the date of issuance of
               such additional shares.

          A =  the number of shares outstanding immediately after the
               issuance of such additional shares.

          The adjustment shall be made successively whenever any such
issuance is made, and shall become effective immediately after such issuance.

          This subsection (d) does not apply to:

               (1)  any of the transactions described in subsections (a),
     (b)and (c) of this Section 15,

               (2)  the exercise of Warrants or other warrants outstanding on

<PAGE>


     the date of this Agreement, or the conversion or exchange of other
     securities convertible or exchangeable for Common Stock,

               (3)  Common Stock issued and issuable upon the exercise of
     options issued to the Company's directors, officers and employees under
     bona fide employee benefit plans adopted by the Board of Directors and
     approved by the holders of Common Stock when required by law or
     otherwise where such issuances have been approved by the Board of
     Directors (but only to the extent that the aggregate number of shares
     excluded hereby and issued after the date of this Agreement shall not
     exceed 1% of the Common Stock outstanding at the time of issuance),

               (4)  Common Stock issuable upon the exercise of rights or
     warrants issued to the holders of Common Stock,

               (5)  Common Stock issued to shareholders of any person which
     merges into the Company in proportion to their stock holdings of such
     person immediately prior to such merger, upon such merger,

               (6)  Common Stock issued in a bona fide public offering
     pursuant to a firm commitment underwriting, or

               (7)  Common Stock issued in a bona fide private placement
     through a placement agent which is a member firm of the National
     Association of Securities Dealers, Inc. (except to the extent that any
     discount from the current market price attributable to restrictions on
     transferability of the Common Stock, as determined in good faith by the
     Board of Directors and described in a Board resolution which shall be
     filed with the Warrant Agent, shall exceed 20%).

          (e)  Adjustment for Convertible Securities Issue.

          If the Company issues any securities convertible into or
exchangeable for Common Stock (other than securities issued in transactions
described in subsections (a), (b) and (c) of this Section 15) for a
consideration per share (including the minimum consideration per share
payable upon conversion of any securities convertible into or exchangeable
for Common Stock) of Common Stock initially deliverable upon conversion or
exchange of such securities less than the current market price per share on
the date of issuance of such securities, the Exercise Price shall be adjusted
in accordance with this formula:

                            P
                            -
          E'  =  E  x   O + M
                        -----
                        O + D

          where:

          E' = the adjusted Exercise Price.

          E =  the then current Exercise Price.

          O =  the number of shares outstanding immediately prior to the
               issuance of such securities.

          P =  the aggregate consideration received for the issuance of such
               securities.

          M =  the current market price per share on the date of issuance of
               such securities.

          D =  the maximum number of shares deliverable upon conversion of or

<PAGE>

               in exchange for such securities at the initial conversion or
               exchange rate.

          The adjustment shall be made successively whenever any such
issuance is made, and shall become effective immediately after such issuance.

          If all of the Common Stock deliverable upon conversion or exchange
of such securities has not been issued when such securities are no longer
outstanding, then the Exercise Price shall promptly be readjusted to the
Exercise Price which would then be in effect had the adjustment upon the
issuance of such securities been made on the basis of the actual number of
shares of Common Stock issued upon conversion or exchange of such securities.

          This subsection (e) does not apply to:

               (1)  convertible securities issued to shareholders of any
     person which merges into the Company, or with a subsidiary of the
     Company, in proportion to their stock holdings of such person
     immediately prior to such merger, upon such merger,

               (2)  convertible securities issued in a bona fide public
     offering pursuant to a firm commitment underwriting,

               (3)  convertible securities issued in a bona fide private
     placement through a placement agent which is a member firm of the
     National Association of Securities Dealers, Inc. (except to the extent
     that any discount from the current market price attributable to
     restrictions on transferability of Common Stock issuable upon
     conversion, as determined in good faith by the Board of Directors and
     described in a Board resolution which shall be filed with the Trustee,
     shall exceed 20% of the then current market price) or

               (4)  stock options issued to the Company's directors, officers
     or employees.

          (f)  Adjustment for Tender or Exchange Offer.

          If the Company or any Subsidiary of the Company consummates a
tender or exchange offer for all or any portion of the Common Stock or any
securities convertible into or exchangeable for Common Stock, to the extent
that the cash and value of any other consideration included in such payment
per share of Common Stock (determined on an as-converted basis in the case of
any such convertible or exchangeable securities so tendered or exchanged)
exceeds the average of the Quoted Prices (as defined in subsection (g) of
this Section 15) of the Common Stock for the five consecutive trading days
(the "Adjustment Period") commencing on the first trading day (such trading
day, the "First Trading Day") immediately following the last time tenders or
exchanges may be made pursuant to such tender or exchange offer (the
"Expiration Time"), the Exercise Price shall be adjusted in accordance with
this formula:

          E'  =  E  x   O x  M     
                        -----------
                        P + (A x M)

          E' = the adjusted Exercise Price.

<PAGE>


          E =  the current Exercise Price.

          O =  the number of shares of Common Stock outstanding immediately
               prior to the Expiration Time, including, in the case of any
               tender or exchange offer in respect of securities convertible
               into or exchangeable for Common Stock, any shares of Common
               Stock issuable upon the conversion or exchange of such
               securities.

          M =  the average of the Quoted Prices (as defined in subsection (g)
               of this Section 15) of the Common Stock for the Adjustment
               Period.

          P =  the aggregate cash consideration and the fair market value of
               any non-cash consideration payable to stockholders based on
               the number  of shares of Common Stock (or securities
               convertible into or exchangeable for Common Stock) tendered or
               exchanged (and not withdrawn) in connection with the tender or
               exchange offer and accepted by the Company.  The Board of
               Directors shall determine the fair market value of any non-
               cash consideration.

          A=   the number of shares of Common Stock outstanding at the time
               of acceptance by the Company of any shares of Common Stock (or
               securities convertible into or exchangeable for Common Stock)
               so tendered or exchanged and accepted by the Company,
               including, in the case of any tender or exchange offer in
               respect of securities convertible into or exchangeable for
               Common Stock, any shares of Common Stock issuable upon the
               conversion or exchange of such securities.

<PAGE>


          The adjustment shall be made successively whenever any such tender
or exchange offer is made.  To the extent a Warrant holder exercises such
holder's Warrant(s) prior to the conclusion of the Adjustment Period, any
adjustment in the number of Warrant Shares issuable upon exercise of such
Warrant(s) shall be for the benefit of the holder of record of such
Warrant(s) at the close of trading on the First Trading Day.

          This subsection (f) does not apply to redemptions of securities
pursuant to redemption provisions contained in the certificate of designation
pertaining to such securities in effect at the time such securities were
issued, whether such redemptions are optional or mandatory.

          (g)  Current Market Price.

          In subsections (b), (c), (d) and (e) of this Section 15, the
current market price per share of Common Stock on any date is the average of
the Quoted Prices of the Common Stock for 30 consecutive trading days
commencing 45 trading days before the date in question.  The "Quoted Price"
of the Common Stock is the last reported sales price of the Common Stock on
any national securities exchange on which the Common Stock is listed which
shall be for consolidated trading if applicable to such exchange, or if not
so listed, the last reported bid price of the Common Stock.  In the absence
of one or more such quotations, the Board of Directors of the Company shall
determine the current market price on such basis as it in good faith
considers appropriate.

          (h)  Consideration Received.

          For purposes of any computation respecting consideration received
pursuant to subsections (d) and (e) of this Section 15, the following shall
apply:

               (1)  in the case of the issuance of shares of Common Stock for
     cash, the consideration shall be the amount of such cash, provided that
     in no case shall any deduction be made for any commissions, discounts or
     other expenses incurred by the Company for any underwriting of the issue
     or otherwise in connection therewith;

               (2)  in the case of the issuance of shares of Common Stock for
     a consideration in whole or in part other than cash, the consideration
     other than cash shall be deemed to be the fair market value thereof as
     determined in good faith by the Board of Directors (irrespective of the
     accounting treatment thereof), whose determination shall be conclusive,
     and described in a Board resolution which shall be filed with the
     Warrant Agent; and

               (3)  in the case of the issuance of securities convertible
     into or exchangeable for shares, the aggregate consideration received
     therefor shall be deemed to be the consideration received by the Company
     for the issuance of such securities plus the additional minimum
     consideration, if any, to be received by the Company upon the conversion
     or exchange thereof (the consideration in each case to be determined in
     the same manner as provided in clauses (1) and (2) of this subsection).

<PAGE>

          (i)  When De Minimis Adjustment May Be Deferred.

          No adjustment in the Exercise Price need be made unless the
adjustment would require an increase or decrease of at least 1% in the
Exercise Price.  Any adjustments that are not made shall be carried forward
and taken into account in any subsequent adjustment.

          All calculations under this Section 15 shall be made to the nearest
cent or to the nearest 1/100th of a share, as the case may be.

          (j)  When No Adjustment Required.

          No adjustment need be made for a transaction referred to in
subsections (a), (b),(c), (d), (e) or (f) of this Section 15 if Warrant
holders are to participate in the transaction on a basis and with notice that
the Board of Directors determines to be fair and appropriate in light of the
basis and notice on which holders of Common Stock participate in the
transaction.

          No adjustment need be made for (i) a transaction referred to in
subsections (b), (d) or (e) of this Section 15 if the below market portion of
such issuances, taken together with all other below market issuances and with
all above market tender or exchange offers described in clause (ii) of this
paragraph made on and after the date of this Agreement, is less than 2.0% of
the Total Market Capitalization of the Company (determined by reference to
the sum of the percentages of Total Market Capitalization of the Company
attributable to each such transaction on the date thereof) and (ii) a
transaction referred to in subsection (f) of this Section 15 if the above
market portion of such tender or exchange offers, taken together with all
other above market tender or exchange offers and with all below market
issuances described in clause (i) of this paragraph made on or after the date
of this Agreement, is less than 2.0% of the Total Market Capitalization of
the Company (determined by reference to the sum of the percentages of Total
Market Capitalization of the Company attributable to each such transaction on
the date thereof).

          No adjustment need be made for a change in the par value, or from
par value to no par value, or from no par value to par value, of the Common
Stock.

          To the extent the Warrants become convertible into cash, no
adjustment need be made thereafter as to the cash.  Interest will not accrue
on the cash.

          (k)  Notice of Adjustment.

          Whenever the Exercise Price is adjusted, the Company shall provide
the notices required by Section 17 hereof.

          (l)  Voluntary Reduction.

          The Company from time to time may, as the Board of Directors deems
appropriate, reduce the Exercise Price by any amount for any period of time
if the period is at least 20 days and if the reduction is irrevocable during
the period; provided that in no event may the Exercise Price be less than the
par value of a share of Common Stock.

          Whenever the Exercise Price is reduced, the Company shall mail to

<PAGE>


Warrant holders a notice of the reduction.  The Company shall mail the notice
at least 15 days before the date the reduced Exercise Price takes effect.
The notice shall state the reduced Exercise Price and the period it will be
in effect.

          A voluntary reduction of the Exercise Price pursuant to this
Section 15(k), other than a reduction which the Company has irrevocably
committed will be in effect for so long as any Warrants are outstanding, does
not change or adjust the Exercise Price otherwise in effect for purposes of
subsections (a), (b), (c), (d), (e) and (f) of this Section 15.

          (m)  Reorganization of the Company.

               (1)  If the Company consolidates or merges with or into, or
     transfers or leases all or substantially all its assets to, any person,
     upon consummation of such transaction any Warrants not surrendered for
     repurchase by the Company pursuant to Section 14 hereof shall
     automatically become exercisable for the kind and amount of securities,
     cash or other assets which the holder of a Warrant would have owned
     immediately after the consolidation, merger, transfer or lease if the
     holder had exercised the Warrant immediately before the effective date
     of the transaction.  Concurrently with the consummation of such
     transaction, the corporation formed by or surviving any such
     consolidation or merger if other than the Company, or the person to
     which such sale or conveyance shall have been made (any such person, the
     "Successor Entity"), shall enter into a supplemental Warrant Agreement
     so providing and further providing for adjustments which shall be as
     nearly equivalent as may be practical to the adjustments provided for in
     this Section 15.  The Successor Entity shall mail to Warrant holders a
     notice describing the supplemental Warrant Agreement.  If the issuer of
     securities deliverable upon exercise of Warrants under the supplemental
     Warrant Agreement is an affiliate of the formed, surviving, transferee
     or lessee corporation, that issuer shall join in the supplemental
     Warrant Agreement.

               (2)  If this subsection (m) applies, subsections (a), (b),
     (c), (d), (e) and (f) of this Section 15 do not apply.

          (n)  Company Determination Final.

          Any determination that the Company or the Board of Directors must
make pursuant to subsection (a), (c), (d), (e), (f), (g), (h) or (j) of this
Section 15 is conclusive.


<PAGE>


          (o)  Warrant Agent's Disclaimer.

          The Warrant Agent has no duty to determine when an adjustment under
this Section 15 should be made, how it should be made or what it should be.
The Warrant Agent has no duty to determine whether any provisions of a
supplemental Warrant Agreement under subsection (n) of this Section 15 are
correct.  The Warrant Agent makes no representation as to the validity or
value of any securities or assets issued upon exercise of Warrants.  The
Warrant Agent shall not be responsible for the Company's failure to comply
with this Section 15.

          (p)  When Issuance or Payment May Be Deferred.

          In any case in which this Section 15 shall require that an
adjustment in the Exercise Price be made effective as of or immediately after
a record date for a specified event, the Company may elect to defer until the
occurrence of such event (i) issuing to the holder of any Warrant exercised
after such record date the Warrant Shares and other capital stock of the
Company, if any, issuable upon such exercise over and above the Warrant
Shares and other capital stock of the Company, if any, issuable upon such
exercise on the basis of the Exercise Price prior to such adjustment and
(ii) paying to such holder any amount in cash in lieu of a fractional share
pursuant to Section 17 hereof; provided that the Company shall deliver to
such holder a due bill or other appropriate instrument evidencing such
holder's right to receive such additional Warrant Shares, other capital stock
and cash upon the occurrence of the event requiring such adjustment.

          (q)  Adjustment in Number of Shares.

          Upon each adjustment of the Exercise Price pursuant to this Section
15, each Warrant outstanding prior to the making of the adjustment in the
Exercise Price shall thereafter evidence the right to receive upon payment of
the adjusted Exercise Price that number of shares of Common Stock (calculated
to the nearest hundredth) obtained from the following formula:

          N'  =  N x  E 
                      --
                      E'

          where:

          N' = the adjusted number of Warrant Shares issuable upon exercise
               of a Warrant by payment of the adjusted Exercise Price.

          N =  the number of Warrant Shares previously issuable upon exercise
               of a Warrant by payment of the Exercise Price prior to
               adjustment.

          E' = the adjusted Exercise Price.

          E =  the Exercise Price prior to adjustment.

          (r)  Form of Warrants.

          Irrespective of any adjustments in the Exercise Price or the number
or kind of shares purchasable upon the exercise of the Warrants, Warrants
theretofore or thereafter issued may continue to express the same price and
number and kind of shares as are stated in the Warrants initially issuable
pursuant to this Agreement.

          SECTION 16.  No Dilution or Impairment.  (a) If any event shall
occur as to which the provisions of Section 15 are not strictly applicable

<PAGE>


but the failure to make any adjustment would have the effect of depriving
holders of Warrants of the benefit of all or a portion of the purchase rights
evidenced by the Warrants in accordance with the essential intent and
principles of such Section, then, in each such case, the Company shall
appoint an Independent Financial Expert, which shall give its opinion upon
the adjustment, if any, on a basis consistent with the essential intent and
principles established in Section 15, necessary to preserve, without
dilution, the purchase rights, represented by this Warrant.  Upon receipt of
such opinion, the Company will promptly mail a copy thereof to the holders of
the Warrants and shall make the adjustments described therein.

          (b)  The Company will not, by amendment of its certificate of
incorporation or through any consolidation, merger, reorganization, transfer
of assets, dissolution, issue or sale of securities or any other voluntary
action, avoid or seek to avoid the observance or performance of any of the
terms of the Warrants, but will at all times in good faith assist in the
carrying out of all such terms and in the taking of all such action as may be
necessary or appropriate in order to protect the rights of the holder of the
Warrants against dilution or other impairment.  Without limiting the
generality of the foregoing, the Company (i) will take all such action as may
be necessary or appropriate in order that the Company may validly and legally
issue fully paid and nonassessable shares of Common Stock on the exercise of
the Warrants from time to time outstanding and (ii) will not take any action
which results in any adjustment of the Exercise Price if the total number of
Warrant Shares issuable after the action upon the exercise of all of the
Warrants would exceed the total number of shares of Common Stock then
authorized by the Company's certificate of incorporation and available for
the purposes of issue upon such exercise.  A consolidation, merger,
reorganization or transfer of assets involving the Company covered by
Section 15(m) shall not be prohibited by or require any adjustment under this
Section 16.

          SECTION 17.  Fractional Interests.  The Company shall not be
required to issue fractional Warrant Shares on the exercise of Warrants.  If
more than one Warrant shall be presented for exercise in full at the same
time by the same holder, the number of full Warrant Shares which shall be
issuable upon the exercise thereof shall be computed on the basis of the
aggregate number of Warrant Shares purchasable on exercise of the Warrants so
presented.  If any fraction of a Warrant Share would, except for the
provisions of this Section 17, be issuable on the exercise of any Warrants
(or specified portion thereof), the Company shall notify the Warrant Agent in
writing of the amount to be paid in lieu of the fraction of a Warrant Share
and concurrently pay or provide to the Warrant Agent for payment to the
Warrant holder an amount in cash equal to the product of (i) such fraction of
a Warrant Share multiplied by (ii) the difference of the current market price
of a share of Common Stock over the Exercise Price.

          SECTION 18.  Notices to Warrant Holders.  (a)  Upon any adjustment

<PAGE>


of the Exercise Price pursuant to Section 15 hereof, the Company shall within
15 days thereafter (i) cause to be filed with the Warrant Agent a certificate
of a firm of independent public accountants of recognized standing selected
by the Board of Directors of the Company (who may be the regular auditors of
the Company) setting forth the Exercise Price after such adjustment and
setting forth in reasonable detail the method of calculation and the facts
upon which such calculations are based and setting forth the number of
Warrant Shares (or portion thereof) issuable after such adjustment in the
Exercise Price, upon exercise of a Warrant and payment of the adjusted
Exercise Price, which certificate shall be conclusive evidence of the
correctness of the matters set forth therein, and (ii) cause to be given to
each of the registered holders of the Warrant certificates at such registered
holder's address appearing on the Warrant register written notice of such
adjustments by first-class mail, postage prepaid.  Where appropriate, such
notice may be given in advance and included as a part of the notice required
to be mailed under the other provisions of this Section 18.

          (b)  In case:

             (i)  the Company shall authorize the issuance to all holders of
     shares of Common Stock of rights, options or warrants to subscribe for
     or purchase shares of Common Stock or of any other subscription rights
     or warrants; or

             (ii) the Company shall authorize the distribution to all holders
     of shares of Common Stock of evidences of its indebtedness or assets
     (other than cash dividends or cash distributions payable out of
     consolidated earnings or earned surplus or dividends payable in shares
     of Common Stock or distributions referred to in subsection (a) of
     Section 15 hereof; or

           (iii)  of any consolidation or merger to which the Company is a
     party and for which approval of any shareholders of the Company is
     required, or of the conveyance, transfer or lease of the properties and
     assets of the Company substantially as an entirety, or of any
     reclassification or change of Common Stock issuable upon exercise of the
     Warrants (other than a change in par value, or from par value to no par
     value, or from no par value to par value, or as a result of a
     subdivision or combination), or a tender offer or exchange offer for
     shares of Common Stock; or

             (iv) of the voluntary or involuntary dissolution, liquidation or
     winding up of the Company;

               then the Company shall cause to be filed with the Warrant
     Agent and shall cause to be given to each of the registered holders of
     the Warrant certificates at his address appearing on the Warrant
     register, at least 20 days (or 10 days in any case specified in clauses
     (i) or (ii) above) prior to the applicable record date hereinafter
     specified, or promptly in the case of events for which there is no
     record date, by first-class mail, postage prepaid, a written notice
     stating (A) the date as of which the holders of record of shares of
     Common Stock to be entitled to receive any such rights, options,


<PAGE>

     warrants or distribution are to be determined, or (B) the initial
     expiration date set forth in any tender offer or exchange offer for
     shares of Common Stock or any securities convertible into or
     exchangeable for Common Stock, or (C) the date on which any such
     consolidation, merger, conveyance, transfer, lease, dissolution,
     liquidation or winding up is expected to become effective or
     consummated, and the date as of which it is expected that holders of
     record of shares of Common Stock shall be entitled to exchange such
     shares for securities or other property, if any, deliverable upon such
     reclassification, consolidation, merger, conveyance, transfer,
     dissolution, liquidation or winding up.  The failure to give the notice
     required by this Section 18 or any defect therein shall not affect the
     legality or validity of any distribution, right, option, warrant, tender
     offer or exchange offer, consolidation, merger, conveyance, transfer,
     lease, dissolution, liquidation or winding up, or the vote upon any
     action.

          (c)  If the Company takes any action that would require an
adjustment in the Exercise Price pursuant to subsections (a), (b), (c), (d),
(e) or (f) of Section 15 hereof and the Company does not arrange for Warrant
holders to participate pursuant to subsection (j) of Section 15 hereof, the
Company shall mail to Warrant holders a notice at least 15 days before such
date stating the proposed record date for a dividend or distribution or the
proposed effective date of a subdivision, combination, reclassification,
consolidation, merger, conveyance, transfer, lease, dissolution, liquidation
or winding up or the Expiration Time of a tender or exchange offer.  Failure
to mail the notice or any defect in the notice shall not affect the validity
of the transaction.

          Nothing contained in this Agreement or in any of the Warrant
certificates shall be construed as conferring upon the holders thereof the
right to vote or to consent or to receive notice as shareholders in respect
of the meetings of shareholders or the election of Directors of the Company
or any other matter, or any rights whatsoever as shareholders of the Company.

          SECTION 19.  Warrant Agent.  The Warrant Agent undertakes the
duties and obligations imposed by this Agreement upon the following terms and
conditions, by all of which the Company and the holders of Warrants, by their
acceptance thereof, shall be bound.

          (a)  The statements contained herein and in the Warrant
certificates shall be taken as statements of the Company.  The Warrant Agent
assumes no responsibility for the correctness of any of the same except such
as describe the Warrant Agent or action taken or to be taken by it.  The
Warrant Agent assumes no responsibility with respect to the distribution of
the Warrant certificates except as herein otherwise provided.

          (b)  The Warrant Agent shall not be responsible for any failure of
the Company to comply with any of the covenants contained in this Agreement

<PAGE>

or in the Warrant certificates to be complied with by the Company.

          (c)  The Warrant Agent may consult at any time with counsel
satisfactory to it (who may be counsel for the Company) and the Warrant Agent
shall incur no liability or responsibility to the Company or to any holder of
any Warrant certificate in respect of any action taken, suffered or omitted
by it hereunder in good faith and in accordance with the opinion or the
advice of such counsel.

          (d)  The Warrant Agent shall incur no liability or responsibility
to the Company or to any holder of any Warrant certificate for any action
taken in reliance on any Warrant certificate, certificate of shares, notice,
resolution, waiver, consent, order, certificate, or other paper, document or
instrument believed by it to be genuine and to have been signed, sent or
presented by the proper party or parties.  The Warrant Agent shall not be
bound by any notice or demand, or any waiver, modification, termination or
revision of this Agreement or any of the terms hereof, unless evidenced by a
writing between the Company and the Warrant Agent.

          (e)  The Company agrees to pay to the Warrant Agent reasonable
compensation for all services rendered by the Warrant Agent in the execution
of this Agreement, to reimburse the Warrant Agent for all expenses, taxes
(including withholding taxes) and governmental charges and other charges of
any kind and nature incurred by the Warrant Agent in the execution, delivery
and performance of its responsibilities under this Agreement and to indemnify
the Warrant Agent and save it harmless against any and all liabilities,
including judgments, costs and counsel fees, for anything done or omitted by
the Warrant Agent in the execution, delivery and performance of its
responsibilities under this Agreement except as a result of its negligence or
bad faith.

          (f)  The Warrant Agent shall be under no obligation to institute
any action, suit or legal proceeding or to take any other action likely to
involve expense unless the Company or one or more registered holders of
Warrant certificates shall furnish the Warrant Agent with reasonable security
and indemnity for any costs and expenses which may be incurred, but this
provision shall not affect the power of the Warrant Agent to take such action
as it may consider proper, whether with or without any such security or
indemnity.  All rights of action under this Agreement or under any of the
Warrants may be enforced by the Warrant Agent without the possession of any
of the Warrant certificates or the production thereof at any trial or other
proceeding relative thereto, and any such action, suit or proceeding
instituted by the Warrant Agent shall be brought in its name as Warrant Agent
and any recovery of judgment shall be for the ratable benefit of the
registered holders of the Warrants, as their respective rights or interests
may appear.

          (g)  Except as required by law, the Warrant Agent, and any
stockholder, director, officer or employee of the Warrant Agent, may buy,
sell or deal in any of the Warrants or other securities of the Company or
become pecuniarily interested in any transaction in which the Company may be


<PAGE>

interested, or contract with or lend money to the Company or otherwise act as
fully and freely as though it were not Warrant Agent under this Agreement.
Nothing herein shall preclude the Warrant Agent from acting in any other
capacity for the Company or for any other legal entity.

          (h)  The Warrant Agent shall act hereunder solely as agent for the
Company, and its duties shall be determined solely by the provisions hereof.
The Warrant Agent shall not be liable for anything which it may do or refrain
from doing in connection with this Agreement except for its own negligence or
bad faith.

          (i)  The Warrant Agent shall not at any time be under any duty or
responsibility to any holder of any Warrant certificate to make or cause to
be made any adjustment of the Exercise Price or number of the Warrant Shares
or other securities or property deliverable as provided in this Agreement, or
to determine whether any facts exist which may require any of such
adjustments, or with respect to the nature or extent of any such adjustments,
when made, or with respect to the method employed in making the same.  The
Warrant Agent shall not be accountable with respect to the validity or value
or the kind or amount of any Warrant Shares or of any securities or property
which may at any time be issued or delivered upon the exercise of any Warrant
or with respect to whether any such Warrant Shares or other securities will
when issued be validly issued and fully paid and nonassessable, and makes no
representation with respect thereto.

          SECTION 20.  Merger, Consolidation or Change of Name of Warrant
Agent.  Any corporation into which the Warrant Agent may be merged or with
which it may be consolidated, or any corporation resulting from any merger or
consolidation to which the Warrant Agent shall be a party, or any corporation
succeeding to the business of the Warrant Agent, shall be the successor to
the Warrant Agent hereunder without the execution or filing of any paper or
any further act on the part of any of the parties hereto; provided that such
corporation would be eligible for appointment as a successor warrant agent
under the provisions of Section 21 hereof.  To the extent practicable, the
Warrant Agent shall provide prior written notice to the Company of any such
merger, consolidation, succession or similar change with respect to the
Warrant Agent; provided, however, that the failure to deliver such notice
will not affect the rights of any of the parties hereto.  In case at the time
such successor to the Warrant Agent shall succeed to the agency created by
this Agreement, and in case at that time any of the Warrant certificates
shall have been countersigned but not delivered, any such successor to the
Warrant Agent may adopt the countersignature of the original Warrant Agent;
and in case at that time any of the Warrant certificates shall not have been
countersigned, any successor to the Warrant Agent may countersign such
Warrant certificates either in the name of the predecessor Warrant Agent or
in the name of the successor to the Warrant Agent; and in all such cases such

<PAGE>

Warrant certificates shall have the full force and effect provided in the
Warrant certificates and in this Agreement.

          In case at any time the name of the Warrant Agent shall be changed
and at such time any of the Warrant certificates shall have been
countersigned but not delivered, the Warrant Agent whose name has been
changed may adopt the countersignature under its prior name, and in case at
that time any of the Warrant certificates shall not have been countersigned,
the Warrant Agent may countersign such Warrant certificates either in its
prior name or in its changed name, and in all such cases such Warrant
certificates shall have the full force and effect provided in the Warrant
certificates and in this Agreement.

          SECTION 21.  Change of Warrant Agent.  If the Warrant Agent shall
become incapable of acting as Warrant Agent or shall resign as provided
below, the Company shall appoint a successor to such Warrant Agent.  If the
Company shall fail to make such appointment within a period of 30 days after
it has been notified in writing of such incapacity by the Warrant Agent or by
the registered holders of a majority of Warrant certificates, then the
registered holder of any Warrant certificate may apply to any court of
competent jurisdiction for the appointment of a successor to the Warrant
Agent.  Pending appointment of a successor to such Warrant Agent, either by
the Company or by such a court, the duties of the Warrant Agent shall be
carried out by the Company.  The holders of a majority of the unexercised
Warrants shall be entitled at any time to remove the Warrant Agent and
appoint a successor to such Warrant Agent.  Such successor to the Warrant
Agent need not be approved by the Company or the former Warrant Agent.  After
appointment the successor to the Warrant Agent shall be vested with the same
powers, rights, duties and responsibilities as if it had been originally
named as Warrant Agent without further act or deed; but the former Warrant
Agent shall deliver and transfer to the successor to the Warrant Agent any
property at the time held by it hereunder and execute and deliver any further
assurance, conveyance, act or deed necessary for the purpose.  Failure to
give any notice provided for in Section 21, however, or any defect therein,
shall not affect the legality or validity of the appointment of a successor
to the Warrant Agent.

          The Warrant Agent may resign at any time and be discharged from the
obligations hereby created by so notifying the Company in writing at least 30
days in advance of the proposed effective date of its resignation.  If no
successor Warrant Agent accepts the engagement hereunder by such time, the
Company shall act as Warrant Agent.

          SECTION 22.  Notices to the Company and Warrant Agent.  Any notice
or demand authorized by this Agreement to be given or made by the Warrant
Agent or by the registered holder of any Warrant certificate to or on the
Company shall be sufficiently given or made when and if deposited in the
mail, first class or registered, postage prepaid, addressed (until another
address is filed in writing by the Company with the Warrant Agent), as
follows:

any ambiguity or to correct or supplement any provision contained herein
which may be defective or inconsistent with any other provision herein, or to
make any other provisions in regard to matters or questions arising hereunder
which the Company and the Warrant Agent may deem necessary or desirable and
which shall not in any way materially adversely affect the interests of the
holders of Warrant certificates.  Any amendment or supplement to this
Agreement that has a material adverse effect on the interests of holders

Warrant certificate 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 in the State of New York.  The Company irrevocably consents to the
jurisdiction of any United States or State Court located in the State of New
York in any suit or proceeding based on or arising under this Agreement or
the Warrant certificates and irrevocably agrees that all claims in respect of
such suit or proceeding may be determined in any such court.  The Company
irrevocably waives the defense of an inconvenient forum to the maintenance of
such suit or proceeding.  The Company hereby agrees to designate and appoint
CT Corporation System, 1633 Broadway, New York, NY  10019 as an agent upon
whom process may be served in any suit or proceeding based on or arising
under this Agreement.  The Company further agrees that service of process
upon the Company, or upon an agent appointed pursuant to the preceding
sentence accompanied with written notice of said service to the Company, as
the case may be, mailed by first class mail shall be deemed in every respect
effective service of process upon the Company in any such suit or proceeding.
Nothing herein shall affect the Warrant Agent's or any Warrant holder's right
to serve process in any other manner permitted by law.  The Company agrees
that a final non-appealable judgment in any such suit or proceeding shall be
conclusive and may be enforced in other jurisdictions by suit on such
judgment or in any other lawful manner.

          SECTION 27.  Benefits of This Agreement.  Nothing in this Agreement
shall be construed to give to any person or corporation other than the
Company, the Warrant Agent and the registered holders of the Warrant
certificates any legal or equitable right, remedy or claim under this
Agreement; but this Agreement shall be for the sole and exclusive benefit of
the Company, the Warrant Agent and the registered holders of the Warrant
certificates.

          SECTION 28.  Counterparts.  This Agreement may be executed in any
number of counterparts and each of such counterparts shall for all purposes
be deemed to be an original, and all such counterparts shall together
constitute but one and the same instrument.

          SECTION 29.  Further Assurances.  From time to time on and after
the date hereof, the Company shall deliver or cause to be delivered to the
Warrant Agent such further documents and instruments and shall do and cause
to be done such further acts as the Warrant Agent shall reasonably request
(it being understood that the Warrant Agent shall have no obligation to make
such request) to carry out more effectively the provisions and purposes of
this Agreement, to evidence compliance herewith or to assure itself that it
is protected hereunder.

     OFFERED OR SOLD WITHIN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR

     TO THE RESTRICTIONS ON TRANSFER OF THIS SECURITY (THE FORM OF WHICH
     LETTER CAN BE OBTAINED FROM THE WARRANT AGENT) AND AN OPINION OF COUNSEL

     THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE 144 UNDER THE
     SECURITIES ACT (IF AVAILABLE) OR (F) PURSUANT TO AN EFFECTIVE
     REGISTRATION STATEMENT UNDER THE SECURITIES ACT AND (3) AGREES THAT IT
     WILL DELIVER TO EACH PERSON TO WHOM THIS SECURITY IS TRANSFERRED A
     NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND.  IN CONNECTION WITH
     ANY TRANSFER OF THIS SECURITY WITHIN THREE YEARS AFTER THE LATER OF THE
     ORIGINAL ISSUANCE OF THE SECURITY OR THE LAST DATE ON WHICH THIS

     ACCREDITED INVESTOR, THE HOLDER MUST, PRIOR TO SUCH TRANSFER, FURNISH TO
     THE WARRANT AGENT AND THE COMPANY SUCH CERTIFICATIONS, LEGAL OPINIONS OR
     OTHER INFORMATION AS EITHER OF THEM MAY REASONABLY REQUIRE TO CONFIRM
     THAT SUCH TRANSFER IS BEING MADE PURSUANT TO AN EXEMPTION FROM, OR IN A
     TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE
     SECURITIES ACT. AS USED HEREIN, THE TERMS "OFFSHORE TRANSACTION,"
     "UNITED STATES" AND "U.S. PERSON" HAVE THE MEANINGS GIVEN TO THEM BY
     REGULATION S UNDER THE SECURITIES ACT.  THE WARRANT AGREEMENT CONTAINS A
     PROVISION REQUIRING THE WARRANT AGENT TO REFUSE TO REGISTER ANY TRANSFER
     OF THIS SECURITY IN VIOLATION OF THE FOREGOING RESTRICTIONS.

By accepting a Warrant certificate bearing the legend above, each holder
shall be bound by all of the terms and provisions of the Warrant Agreement (a

<PAGE>

copy of which is available on request to the Company or the Warrant Agent) as
fully and effectively as if such holder had signed the same.

          The Warrants evidenced by this Warrant Certificate are part of a
duly authorized issue of Warrants expiring July 15, 2005 entitling the holder
upon exercise to receive shares of Common Stock of the Company (the "Common
Stock"), and are issued or to be issued pursuant to a Warrant Agreement,
dated as of June 30, 1995 (the "Warrant Agreement"), duly executed and
delivered by the Company to IBJ Schroder Bank & Trust Company, as Warrant
Agent (the "Warrant Agent"), which Warrant Agreement is hereby incorporated
by reference in and made a part of this instrument and is hereby referred to
for a description of the rights, limitation of rights, obligations, duties
and immunities thereunder of the Warrant Agent, the Company and the holders
(the words "holders" or "holder" meaning the registered holders or registered
holder) of the Warrants.

          Warrants may be exercised at any time on or after 9:00 a.m., New
York, New York time on January 6, 1996 to 5:00 p.m., New York, New York time

Certificate may exercise them by surrendering this Warrant Certificate, with
the form of election to purchase set forth hereon properly completed and
executed, together with payment of the Exercise Price in the form of cash or
certified or official bank check payable to the order of the Company, at the
office of the Warrant Agent.  In the event that upon any exercise of Warrants
evidenced hereby the number of Warrants exercised shall be less than the
total number of Warrants evidenced hereby, there shall be issued to the
holder hereof or his assignee a new Warrant Certificate evidencing the number
of Warrants not exercised.

          The Warrant Agreement provides that upon the occurrence of certain
events the Exercise Price set forth on the face hereof may, subject to
certain conditions, be adjusted.  If the Exercise Price is adjusted, the
Warrant Agreement provides that the number of shares of Common Stock issuable
upon the exercise of each Warrant shall be adjusted.  No fractions of a share
of Common Stock will be issued upon the exercise of any Warrant, but the
Company will pay the cash value thereof determined as provided in the Warrant
Agreement.

          Warrant Certificates, when surrendered at the office of the Warrant
Agent by the registered holder thereof in person or by legal representative
or attorney duly authorized in writing, may be exchanged, in the manner and
subject to the limitations provided in the Warrant Agreement, but without
payment of any service charge, for another Warrant Certificate or Warrant
Certificates of like tenor evidencing in the aggregate a like number of
Warrants.

          Upon due presentation for registration of transfer of this Warrant
Certificate at the office of the Warrant Agent a new Warrant Certificate or

<PAGE>

Warrant Certificates of like tenor and evidencing in the aggregate a like
number of Warrants shall be issued to the transferee(s) in exchange for this
Warrant Certificate, subject to the limitations provided in the Warrant
Agreement, without charge except for any tax or other governmental charge
imposed in connection therewith.

          The Company and the Warrant Agent may deem and treat the registered
holder(s) thereof as the absolute owner(s) of this Warrant Certificate
(notwithstanding any notation of ownership or other writing hereon made by
anyone), for the purpose of any exercise hereof, of any distribution to the
holder(s) hereof, and for all other purposes, and neither the Company nor the
Warrant Agent shall be affected by any notice to the contrary.  Neither the
Warrants nor this Warrant Certificate entitles any holder hereof to any
rights of a stockholder of the Company.

than January 6, 1996; provided, that, if due to applicable law, or any
applicable interpretation of the staff of the SEC, such registration does not

period a Resale Shelf Registration Statement.  The Company agrees to use all

<PAGE>

reasonable best efforts to keep the Registration Statement continuously
effective until the date that is 30 days after the Expiration Date.  The
Company further agrees to supplement or amend the Registration Statement, if
required by the rules, regulations or instructions applicable to the
registration form used by the Company for the Registration Statement or by
the Securities Act or by any other rules and regulations thereunder for shelf
registration or if reasonably requested by a Holder with respect to
information relating to such Holder in order to accurately reflect
information regarding such Holder or such Holder's plan of distribution as
required by the Registration Statement, and to use its best efforts to cause
any such amendment to become effective and such Registration Statement to
become usable as soon as thereafter practicable.  The Company agrees to
furnish to the Holders copies of any such supplement or amendment promptly
after its being made available for use or filed with the SEC.  In addition to
the registration requirements of the Company provided for above, the Company
shall effect any other registration within the United States, within the time
period provided for in the first sentence of this paragraph, that may be
required in order to enable the holders of the Warrants to exercise their
right to purchase Warrant Shares thereunder.

          (b)(i)  The Holders whose Registrable Securities are covered by a
Resale Shelf Registration Statement who desire to do so may sell Registrable
Securities in an Underwritten Offering subject to the limitations set forth
in the proviso to the first sentence of Section 3(o) hereunder (including the
Company's obligation to use its best efforts in connection therewith).  In
any such Underwritten Offering, the investment banker or investment bankers
and manager or managers (the "Underwriters") that will administer the
offering will be selected by the holders of a majority of the Registrable
Securities (determined on an as-converted basis) included in such offering.

          (ii)  Each Holder whose Registrable Securities are covered by a
Resale Shelf Registration Statement agrees, upon the request of the
Underwriter(s) in any Underwritten Offering permitted pursuant to this
Agreement, not to effect any public sale or distribution of securities of the
Company of the same class as the Registrable Securities included in such
Resale Shelf Registration Statement (except as part of such registration),
including a sale pursuant to Rule 144 under the Securities Act, during the
10-day period prior to, and during the 90-day period beginning on, the
closing date of any such Underwritten Offering made pursuant to such Resale
Shelf Registration Statement, to the extent timely notified in writing by the
Company or such Underwriter(s).

          The foregoing provision shall not apply to any Holder if such
Holder is prevented by applicable statute or regulation from entering into


<PAGE>

any such agreement; provided, however, that any such Holder shall undertake,
in its request to participate in any such Underwritten Offering, not to
effect any public sale or distribution of any of its Registrable Securities
not sold in such Underwritten Offering, commencing on the date of sale of
Registrable Securities pursuant to such Underwritten Offering and ending on
the date that is 90 days after the closing date of such Underwritten
Offering, unless it has provided 45 days' prior written notice of such sale
or distribution to the Underwriter(s).

          (iii)  The Company agrees not to effect any public or private
offer, sale or distribution of securities of the same quality and nature as
the Registrable Securities, including a sale pursuant to Regulation D under
the Act, during the 10-day period prior to, and during the 90-day period
beginning on, the closing date of each Underwritten Offering permitted
pursuant to Section 3(o) hereof made pursuant to the Registration Statement,
to the extent timely notified in writing by the Underwriter(s).

          (c)  The Company shall pay all Registration Expenses in connection
with any registration pursuant to Section 2(a).  Each Holder shall pay all
underwriting discounts and commissions and transfer taxes, if any, relating
to the sale or disposition of such Holder*s Registrable Securities pursuant
to the Registration Statement.

          (d)  Without limiting the remedies available to the Initial
Purchaser and subsequent Holders, the Company acknowledges that any failure
by the Company to comply with its obligations under Section 2(a) hereof may
result in material irreparable injury to the Initial Purchaser and/or
subsequent 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 subsequent Holder
may obtain such relief as may be required to specifically enforce the
Company's obligations under Section 2(a) hereof.

          3.  Registration Procedures.  In connection with the obligations of
the Company with respect to Section 2(a) hereof, the Company shall, as
expeditiously as possible:

          (a)  prepare and file with the SEC a Registration Statement on the
     appropriate form under the Securities Act, which form shall, (x) be
     selected by the Company and (y) comply as to form in all material
     respects with the requirements of the applicable form and include all
     financial statements required by the SEC to be filed therewith, and use
     all reasonable best efforts to cause such Registration Statement to
     become effective and remain effective in accordance with Section 2
     hereof;


<PAGE>

          (b)  prepare and file with the SEC such amendments and post-
     effective amendments to the Registration Statement as may be necessary
     to (x) keep such Registration Statement effective for the applicable
     period under this Agreement and (y) cause each Prospectus to be
     supplemented by any required prospectus supplement and, as so
     supplemented, to be filed pursuant to Rule 424 under the Securities Act
     and (z) keep each Prospectus current during the period described under
     Section 4(3) and Rule 174 under the Securities Act that is applicable to
     transactions by brokers or dealers with respect to the securities

          (c)  in the case of a registration pursuant to a Resale Shelf

     Initial Purchaser, to counsel for the Holders and to each Underwriter of
     an Underwritten Offering of Registrable Securities, if any, and each
     such Underwriter's Counsel, without charge, as many copies of each
     Prospectus, including each preliminary Prospectus, and any amendment or
     supplement thereto and such other documents as such Holder or
     Underwriter may reasonably request, in order to facilitate the public
     sale or other disposition of the Registrable Securities; the Company
     consents to the use of such Prospectus and any amendment or supplement
     thereto in accordance with applicable law by each of the Holders selling
     Registrable Securities and any such Underwriters in connection with the
     offering and sale of the Registrable Securities covered by and in the
     manner described in such Prospectus or any amendment or supplement
     thereto in accordance with applicable law;

          (d)  use its reasonable best efforts to register or qualify the
     Registrable Securities under all applicable state securities or "blue
     sky" laws of such jurisdictions as any Holder with Registrable
     Securities covered by a Registration Statement shall reasonably request
     in writing by the time the Registration Statement is declared effective
     by the SEC, to cooperate with such Holders in connection with any
     filings required to be made with the National Association of Securities
     Dealers, Inc. 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; provided, however, that the Company shall not be required to
     (i) qualify as a foreign entity or as a dealer in securities in any
     jurisdiction where it would not otherwise be required to qualify but for

<PAGE>

     this Section 3(d), (ii) file any general consent to service of process
     or (iii) subject itself to taxation in any such jurisdiction if it is

          (e)  in the case of the Resale Shelf Registration Statement, notify
     each Holder, counsel for the Holders and counsel for the Initial
     Purchaser promptly and, if requested by any such Holder, confirm such
     advice in writing, (i) when the Resale Shelf Registration Statement has
     become effective and when any post-effective amendments and supplements
     thereto have been filed and become effective, (ii) of any request by the
     SEC or any state securities authority for amendments and supplements to
     the Resale Shelf Registration Statement and related Prospectus or for
     additional information after the Resale Shelf Registration Statement has

     securities authority of any stop order suspending the effectiveness of
     the Resale Shelf Registration Statement or the initiation of any
     proceedings for that purpose, (iv) if, between the effective date of the
     Resale Shelf 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
     or if the Company receives any notification with respect to the
     suspension of the qualification of the Registrable Securities for sale
     in any jurisdiction or the initiation of any proceeding for such
     purpose, (v) of the happening of any event which makes any statement
     made in the Resale Shelf Registration Statement or the related
     Prospectus untrue in any material respect or which requires the making
     of any changes in the Resale Shelf Registration Statement or Prospectus
     in order to make the statements therein not misleading and (vi) of any
     determination by the Company that a post-effective amendment to the
     Resale Shelf Registration Statement would be appropriate;

          (f)  make every reasonable effort to obtain the withdrawal of any

     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 Registrable Securities, such Prospectus
     will not contain 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 the occurrence of such an event and each

     Registrable Securities, such letters to be in customary form and
     covering matters of the type customarily covered in "cold comfort"
     letters in connection with Underwritten Offerings, and (iv) deliver such
     documents and certificates as may be reasonably requested by the Holders
     of a majority of the Registrable Securities being sold (determined on an
     as-converted basis) or any Underwriter, and which are customarily
     delivered in Underwritten Offerings, to evidence the continued validity
     of the representations and warranties of the Company made pursuant to
     clause (i) above and to evidence compliance with any customary
     conditions contained in an underwriting agreement; provided that the
     Company shall be required to use its best efforts to make an
     Underwritten Offering only upon the request of Holders of the greater of
     (x) at least 25% of the Registrable Securities outstanding (determined
     on an as-converted basis) at the time such request is delivered to the
     Company and (y) 621,000 shares of Common Stock (determined on an as-
     converted basis after giving effect to any stock splits, combinations or
     reclassifications).  In the case of any Underwritten Offering, the
     Company shall provide written notice to the Holders of such Underwritten
     Offering at least 30 days prior to the filing of a prospectus supplement
     for such Underwritten Offering, (y) specify a date, which shall be no
     earlier than 10 days following the date of such notice, by which each
     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.

          In the case of a Resale Shelf Registration Statement, the Company
may require each Holder to furnish to the Company such information regarding
the Holder and the proposed distribution by such Holder of Registrable
Securities as the Company may from time to time reasonably request in
writing.  Each such Holder shall provide the Company with any such
information within five business days after such information is requested and
shall provide to the Company, within five business days after such Holder
receives a draft of the Registration Statement or amendment thereto in which
such information is included, comments on such Registration Statement or
amendment thereto.

          Each Holder agrees that, upon receipt of any notice from the
Company of the happening of any event of the kind described in
Section 3(e)(iii), (v) or (vi) hereof, such Holder will forthwith discontinue

<PAGE>


disposition of Registrable Securities pursuant to the Resale Shelf
Registration Statement until such Holder's receipt of the copies of the
supplemented or amended Prospectus contemplated by Section 3(i) hereof and,
if so directed by the Company, such Holder will deliver to the Company (at
its expense) all copies in its possession, 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.

          4.  Indemnification and Contribution.  (a)  The Company agrees to
indemnify and hold harmless the Initial Purchaser, each Holder and each
person, if any, who controls the Initial Purchaser or any Holder within the
meaning of either Section 15 of the Securities Act or Section 20 of the
Exchange Act or is under common control with or is controlled by the Initial
Purchaser or any Holder and each of their respective directors and officers
(each a "Non-Company Indemnitee") from and against any and all losses,
claims, damages, liabilities and expenses (including, without limitation, any
legal or other expenses reasonably incurred by the Non-Company Indemnitee in
connection with defending or investigating any such action or claim) arising
out of or based upon any untrue statement or alleged untrue statement of a
material fact contained in any Registration Statement (or any amendment or
supplement thereto) pursuant to which Registrable Securities were registered
under the Securities Act, including all documents incorporated therein by
reference, or arising out of or based upon 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, or arising out of or based
upon any untrue statement or alleged untrue statement of a material fact
contained in any Prospectus (as amended or supplemented, if the Company shall
have furnished any amendments or supplements thereto), or caused by any
omission or alleged omission to state therein a material fact necessary to
make the statements therein in light of the circumstances under which they
were made not misleading, except insofar as such losses, claims, damages,
liabilities or expenses arise out of or are based upon any untrue statement
or omission or alleged untrue statement or omission which has been made
therein or omitted therefrom in reliance upon and in conformity with
information relating to the Initial Purchaser or any Holder furnished to the
Company in writing by the Initial Purchaser or any selling Holder expressly
for use therein; provided, however, that the indemnification provided for in
this paragraph (a) shall not inure to the benefit of any Non-Company
Indemnitee with respect to any sale or disposition of Registrable Securities
by such Holder in violation of the provisions of the last paragraph of

<PAGE>


Section 3 hereof.  In connection with any Underwritten Offering contemplated
by Section 3(o), the Company also shall indemnify the Underwriters, if any,
selling brokers, dealers and similar securities industry professionals
participating in the distribution, their officers and directors and each
person who controls such persons (within the meaning of the Securities Act
and the Exchange Act) to the same extent as provided above with respect to
the indemnification of the Holders, if requested in connection with the
Resale Shelf Registration Statement.  The indemnification obligation of the
Company set forth in this paragraph (a) shall be in addition to any liability
which the Company may otherwise have, including, without limitation, for any
breach of any covenant contained in this Agreement.

          (b)  Each Holder agrees, severally and not jointly, to indemnify
and hold harmless the Company, the Initial Purchaser, the other selling
Holders, each of their respective directors and officers and each person, if
any, who controls the Company, the Initial Purchaser, or any other selling
Holder within the meaning of either Section 15 of the Securities Act or
Section 20 of the Exchange Act or is under common control with or is
controlled by the Company, the Initial Purchaser or any other selling Holder
to the same extent as the foregoing indemnity from the Company to the Initial
Purchaser and the Holders, but only with reference to information relating to
such Holder furnished to the Company in writing by such Holder expressly for
use in the Registration Statement (or any amendment thereto) or any
Prospectus (or any amendment or supplement thereto).

          (c)  If any action, suit or proceeding shall be instituted
involving any person in respect of which such person is entitled to indemnity
pursuant to either paragraph (a) or (b) above, such person (the "indemnified
party") shall promptly notify the parties against whom indemnification is
being sought (each an "indemnifying party") and such indemnifying parties
shall assume the defense thereof, including the employment of counsel and
payment of all fees and expenses.  Such indemnified party, shall have the
right to counsel, but the fees and expenses of such counsel shall be at the
expense of such indemnified party unless (i) the indemnifying parties have
agreed in writing to pay such fees and expenses, (ii) the indemnifying
parties shall have 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 indemnifying parties and such
indemnified party and such indemnified party shall have been advised by its
counsel that representation of such indemnified party and any indemnifying
party by the same counsel would be inappropriate under applicable standards
of professional conduct (whether or not such representation by the same

<PAGE>


counsel has been proposed due to actual or potential differing interests
between them (in which case the indemnifying parties shall not have the right
to assume the defense of such action, suit or proceeding on behalf of the
indemnified party)).  It is understood, however, that the indemnifying
parties shall, in connection with any one such action, suit or proceeding, or
substantially similar action, suit or proceeding 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 the Initial Purchaser and all persons, if any, who control the
Initial Purchaser within the meaning of either Section 15 of the Securities
Act or Section 20 of the Exchange Act or is under common control with or is
controlled by the Initial Purchaser, and each of their respective directors
and officers, and the reasonable fees and expenses of only one separate firm
of attorneys (in addition to any local counsel) at any time for all other
Holders and all persons, if any, who control any such Holders within the
meaning of either such Section, or are under common control with or are
controlled by such Holders, and each of their respective directors and
officers.  In such case involving the Initial Purchaser, persons who control,
are controlled by or under common control with the Initial Purchaser, or
their respective directors or officers, such firm shall be designated in
writing by the Initial Purchaser.  In such case involving other Holders and
such persons who control, are controlled by or under common control with such
Holders, or their respective directors or officers, such firm shall be
designated in writing by such Holders holding a majority of the Registrable
Securities sold under the Resale Shelf Registration Statement by all such
Holders.  The indemnifying parties shall not be liable for any settlement of
any action, suit or proceeding effected without their written consent, but if
settled with such written consent or if there be a final judgment for the
plaintiff, the indemnifying parties agree to indemnify and hold harmless the
indemnified party from and against any loss, action, damage, liability or
expense by reason of such settlement or judgment.

          (d)  If the indemnification provided for in this Section 4 is
unavailable to an indemnified party under paragraphs (a) or (b) 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 in
such proportion as is appropriate to reflect the relative fault of the

<PAGE>


indemnifying party or parties, on the one hand, and of the indemnified party
or parties, on the other hand, in connection with such statements or
omissions that resulted in such losses, claims, damages, liabilities or
expenses as well as any other relevant equitable consideration.  The relative
fault of the Company, on the one hand, and any Holder, 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 such Holder, on the other hand, and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission.  The Holders' respective
obligations to contribute pursuant to this Section 4(d) are several in
proportion to the respective number of Registrable Securities of such Holders
that were registered pursuant to the Registration Statement.

          (e)  The Company, the Initial Purchaser and each Holder agree that
it would not be just or equitable if contribution pursuant to this Section 4
were determined by a pro rata allocation 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 and liabilities 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 4, no Holder shall be required to contribute any amount in excess of
the amount by which the total price at which the Registrable Securities sold
by such Holder exceeds the amount of any damages that such Holder has
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 Securities Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.  The remedies provided for in this Section 4
are not exclusive and shall not limit any rights or remedies that may
otherwise be available to any indemnified party at law or in equity.

          (f)  Any losses, claims, damages, liabilities or expenses for which
an indemnified party is entitled to indemnification or contribution under
this Section 4 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 4 shall

<PAGE>


remain operative and in full force and effect, regardless of (i) any
investigation made by or on behalf any indemnified party, (ii) any sale of
Registrable Securities by an indemnified party and (iv) any termination of
this Agreement.  A successor to any indemnified party shall be entitled to
the benefits of the indemnity, contribution and reimbursement agreements
contained in this Section 4.

          (g)  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.

          5.  Miscellaneous.  (a)  No Inconsistent Agreements.  The Company
has not entered into, and on or after the date of this Agreement will not
enter into, any agreement that is inconsistent with the rights granted to the
Holders in this Agreement or otherwise conflicts with the provisions hereof.
The rights granted to the Holders hereunder do not in any way 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.

          (b)  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 the Holders of at least a majority of the outstanding Registrable
Securities affected by such amendment, modification, supplement, waiver or
departure; provided, however, that no amendment, modification, supplement,
waiver or consent to the departure with respect to the provisions of
Section 4 hereof shall be effective as against any person unless consented to
in writing by such person.

          (c)  Notices.  All notices and other communications provided for or
permitted hereunder shall be made in writing by hand-delivery, registered
first-class mail, telex, telecopier or any courier guaranteeing overnight
delivery (i) if to a Holder, at the most current address given by such Holder
to the Company by means of a notice given in accordance with the provisions
of this Section 5(c), which address initially is, with respect to the Initial
Purchaser, the address set forth in the Purchase Agreement; and (ii) if to
the Company, initially at the Company's address set forth in the Purchase

<PAGE>


Agreement, and, thereafter, at such other address, notice of which is given
in accordance with the provisions of this Section 5(c).

          All such notices and communications shall be deemed to have been
duly given: at the time delivered by hand, if personally delivered; five
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 overnight delivery.

          (d)  Successors and Assigns.  This Agreement shall inure to the
benefit of and be binding upon the successors, assigns and transferees of
each of the parties, including, without limitation and without the need for
an express assignment, subsequent Holders; provided that nothing herein shall
be deemed to permit any assignment, transfer or other disposition of
Registrable Securities in violation of the terms of the Purchase Agreement.
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 shall be conclusively
deemed to have agreed to be bound by and to perform all of the terms and
provisions of this Agreement and such person shall be entitled to receive the
benefits hereof.  The Initial Purchaser (in its capacity as Initial
Purchaser) shall have no liability or obligation to the Company with respect
to any failure by any other Holder to comply with, or any breach by any other
Holder of, any of the obligations of such other Holder under this Agreement.

          (e)  Purchases and Sale of Warrant Shares.  The Company shall not,
and shall use its best efforts to cause its affiliates (as defined in Rule
405 under the Securities Act) that it controls not to, purchase and then
resell or otherwise transfer any Warrant Shares.

          (f)  Third Party Beneficiary.  The Holders shall be third party
beneficiaries to the agreements made hereunder between the Company, on the
one hand, and the Initial Purchaser, on the other hand, and the Initial
Purchaser and the Holders shall have the right to enforce such agreements
directly to the extent they deem such enforcement necessary or advisable to
protect the rights of the Initial Purchaser or the Holders hereunder.

          (g)  Counterparts.  This Agreement may be signed in various
counterparts which 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.

          (h)  Headings.  The headings of the Sections of this Agreement have

<PAGE>


been inserted for convenience of reference only and shall not be deemed a
part of this Agreement.

          (i)  Governing Law.  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 in the State of New York.

          (j)  Severability.  In the event that any one or more of the
provisions contained herein, or the application thereof in any circumstance,
is held invalid, illegal or unenforceable, the validity, legality and
enforceability of any such provision in every other respect and of the
remaining provisions contained herein shall not be affected or impaired
thereby.

          (k)  Submission to Jurisdiction.  The Company irrevocably submits
to the jurisdiction of any United States or State court located in the State
of New York in any suit or proceeding based on or arising under this
Agreement and irrevocably agrees that all claims in respect of such suit or
proceeding may be determined in any such court.  The Company irrevocably
waives the defense of an inconvenient forum to the maintenance of such suit
or proceeding.  The Company hereby agrees to designate and appoint CT
Corporation System as an agent upon whom process may be served in any suit or
proceeding based on or arising under this Agreement.  The Company further
agrees that service of process upon the Company, or upon an agent appointed
pursuant to the preceding sentence accompanied with written notice of said
service to the Company, as the case may be, mailed by first class mail shall
be deemed in every respect effective service of process upon the Company in
any such suit or proceeding.  Nothing herein shall affect the Initial
Purchaser*s or any Holder's right to serve process in any other manner
permitted by law.  The Company agrees that a final non-appealable judgment in
any such suit or proceeding shall be conclusive and may be enforced in other
jurisdictions by suit on such judgment or in any other lawful manner.

                  DEFEASANCE SECURITY AGREEMENT


          THIS DEFEASANCE SECURITY AGREEMENT (the "Agreement") is made as of
July 6, 1995 by and among GEOTEK COMMUNICATIONS, INC., a Delaware corporation
("Geotek" or "Pledgor"), and SC FUNDAMENTAL INC., as agent for and on behalf
of THE SC FUNDAMENTAL VALUE FUND, L.P. and SC FUNDAMENTAL VALUE BVI, LTD.
("Pledgees").

                             RECITALS

     A.   Geotek and Pledgees are parties to a Note and Warrant Purchase
Agreement (as the same may be amended, modified, extended or replaced from

Pledgees to hold pursuant to this Agreement, an amount of Governmental
Obligations (as defined in the Note Agreement) the principal of and the
interest on which when due, and without any reinvestment thereof, will
provide a dollar amount equal to the interest payments when due in accordance
with the terms of the Notes (as defined in the Note Agreement) accrued from
the date hereof through September 30, 1996 (the "Final Conversion Date") plus
the principal amount as payable in accordance with the terms of the Notes
through the Final Conversion Date and (ii) to deliver to the Pledgees the
agreement attached hereto as Exhibit A (the "Prepayment Agreement") pursuant
to which Geotek has agreed to prepay, by wire transfer in accordance with

principal amount of the Notes as of the close of business on the Final
Conversion Date.

     C.   Pledgor has purchased (or, in the case of up to $9 million

the Final Conversion Date plus the principal amount as payable in accordance
with the terms of the Notes through the Final Conversion Date plus the amount
to be paid to the Pledgees on the first business day following the Final
Conversion Date in accordance with the Prepayment Agreement, which amounts

defined in Section 2.3 below) in accordance with the terms hereof, the

writing as shall be required to release the security interest granted

Obligations", the "Satisfied Obligations") shall be deemed satisfied and the
Pledgees shall promptly provide written notice to N&B to deliver to the
Pledgor the certificates, instruments and documents evidencing that portion

account of Pledgor) as follows:  (i) in the case of Satisfied Principal
Obligations, such delivery or electronic transfer shall be made within one
(1) business day following each Principal Conversion Date occurring on or
after the date(s) of conversion and (ii) in the case of Satisfied Interest
Obligations, such delivery or electronic transfer shall be made within one
(1) business day following each Interest Payment Date occurring on or after

granted hereunder in such portion of the Pledged Collateral as is equal to
the Satisfied Obligations shall be deemed released immediately,
notwithstanding the date on which such Pledged Collateral is required to be
delivered or transferred to the Pledgor in accordance with the terms hereof.
The delivery of the notice by the Pledgees described in the preceding
sentence shall be a condition to delivery of certificates representing shares
of Common Stock issuable upon conversion of the Notes, and any provision of

above, in addition to any other rights or remedies the Pledgor may have
hereunder or at law or in equity, the parties agree that from and after and
during the continuation of any such default, until such default shall have
