COMMON STOCK PURCHASE WARRANT    
    

        
To Purchase [        ] Shares of Common Stock of
 Advanced Magnetics, Inc.  

 THIS COMMON STOCK PURCHASE WARRANT CERTIFIES that, for value received, [                        ]
 (the "Holder"),
is entitled, upon the terms and subject to the limitations on exercise and the conditions hereinafter set forth, at any time on or after July 2, 2003 (the "Initial
Exercise Date") and on or prior to the close of business on July 1, 2006 (the "Termination Date") but not thereafter, to
subscribe for and purchase from Advanced Magnetics, Inc., a corporation incorporated in the State of Delaware (the "Company"), up to
[    ] shares (the "Warrant Shares") of Common Stock, par value $0.01 per share, of the Company (the
"Common Stock"). The purchase price of one share of Common Stock (the "Exercise Price") under this
Warrant
shall be $15.50, subject to adjustment hereunder. The Exercise Price and the number of Warrant Shares for which the Warrant is exercisable shall be
subject to adjustment as provided herein. Capitalized terms used and not otherwise defined herein shall have the meanings set forth in that certain Securities Purchase
Agreement (the "Purchase Agreement"), dated July 2, 2003, between the Company and the purchasers signatory thereto.

        1.    Title to Warrant.    Prior to the Termination Date and subject to compliance with applicable laws and
Section 7 of this Warrant, this Warrant and all rights hereunder are transferable, in whole or in part, at the office or agency of the Company by the Holder in person or by duly authorized
attorney, upon surrender of this Warrant together with the Assignment Form annexed hereto properly endorsed. The transferee shall sign an investment letter in form and substance reasonably
satisfactory to the Company. 

        2.    Authorization of Shares.    The Company covenants that all Warrant Shares which may be issued upon the exercise
of the purchase rights represented by this Warrant will, upon exercise of the purchase rights represented by this Warrant, be duly authorized, validly issued, fully paid and nonassessable and free
from all taxes, liens and charges in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously with such issue). 

        3.    Exercise of Warrant.    

        (a)   Exercise
of the purchase rights represented by this Warrant may be made at any time or times on or after the Initial Exercise Date and on or before the Termination Date
by submission of 

1

 

the
Notice of Exercise Form annexed hereto duly executed, at the office of the Company (or such other office or agency of the Company as it may designate by notice in writing to the registered Holder
at the address of such Holder appearing on the books of the Company) and upon payment of the Exercise Price of the shares thereby purchased by wire transfer or cashier's check drawn on a United States
bank or by means of a cashless exercise pursuant to Section 3(d), and submission of this Warrant within a reasonable number of days following submission of the Notice of Exercise and payment.
The Holder shall be entitled to receive a certificate for the number of Warrant Shares so purchased. Certificates for shares purchased hereunder shall be delivered to the Holder within five
(5) Trading Days after the date on which this Warrant shall have been exercised as aforesaid. This Warrant shall be deemed to have been exercised and such certificate or certificates shall be
deemed to have been issued, and the Holder or any other person so designated to be named therein shall be deemed to have become a holder of record of such shares for all purposes, as of the date the
Warrant has been exercised by payment to the Company of the Exercise Price and all taxes required to be paid by the Holder, if any, pursuant to Section 5 prior to the issuance of such shares,
have been paid. If the Company fails to deliver to the Holder a certificate or certificates representing the Warrant Shares pursuant to this Section 3(a) by the close of business on the fifth
Trading Day after the date of exercise, then the Holder will have the right to rescind such exercise. In addition to any other rights available to the Holder, if the Company fails to deliver to the
Holder a certificate or certificates representing the Warrant Shares pursuant to an exercise by the close of business on the fifth Trading Day after the date of exercise, and if after such fifth
Trading Day the Holder is required by its broker to purchase (in an open market transaction or otherwise) shares of Common Stock to deliver in satisfaction of a sale by the Holder of the Warrant
Shares which the Holder anticipated receiving upon such exercise (a "Buy-In"), then the Company shall (1) pay in cash to the Holder
the amount by which (x) the Holder's total purchase price (including brokerage commissions, if any) for the shares of Common Stock so purchased exceeds (y) the amount obtained by
multiplying (A) the number of Warrant Shares that the Company was required to deliver to the Holder in connection with the exercise at issue times (B) the price at which the sell order
giving rise to such purchase obligation was executed, and (2) at the option of the Holder, either reinstate the portion of the Warrant and equivalent number of Warrant Shares for which such
exercise was not honored or deliver to the Holder the number of shares of Common Stock that would have been issued had the Company timely complied with its exercise and delivery obligations hereunder.
For example, if the Holder purchases Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted exercise of shares of Common Stock with an
aggregate sale price giving rise to such purchase obligation of $10,000, under clause (1) of the immediately preceding sentence the Company shall be required to pay the Holder $1,000. The
Holder shall provide the Company written notice indicating the amounts payable to the Holder in respect of the Buy-In, together with applicable confirmations and other evidence reasonably
requested by the Company. Nothing herein shall limit a Holder's right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific
performance and/or injunctive relief with respect to the Company's failure to timely deliver certificates representing shares of Common Stock upon exercise of the Warrant as required pursuant to the
terms hereof. 

        (b)   If
this Warrant shall have been exercised in part, the Company shall, at the time of delivery of the certificate or certificates representing Warrant Shares, deliver to
Holder a new Warrant evidencing the
rights of Holder to purchase the unpurchased Warrant Shares called for by this Warrant, which new Warrant shall in all other respects be identical with this Warrant. 

        (c)   The
Company shall not effect any exercise of this Warrant, and the Holder shall not have the right to exercise any portion of this Warrant, pursuant to
Section 3(a) or otherwise, to the extent that after giving effect to such issuance after exercise, the Holder (together with the Holder's Affiliates), as set forth on the applicable Notice of
Exercise, would beneficially own in 

2

 

excess
of 4.99% of the number of shares of the Common Stock outstanding immediately after giving effect to such issuance. For purposes of the foregoing sentence, the number of shares of Common Stock
beneficially owned by the Holder and its Affiliates shall include the number of shares of Common Stock issuable upon exercise of this Warrant with respect to which the determination of such sentence
is being made, but shall exclude the number of shares of Common Stock which would be issuable upon (A) exercise of the remaining, nonexercised portion of this Warrant beneficially owned by the
Holder or any of its Affiliates and (B) exercise or conversion of the unexercised or nonconverted portion of any other securities of the Company (including, without limitation, any other
Debentures or Warrants) subject to a limitation on conversion or exercise analogous to the limitation contained herein beneficially owned by the Holder or any of its Affiliates. Except as set forth in
the preceding sentence, for purposes of this Section 3(c), beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act. For purposes of this
Section 3(c), in determining the number of outstanding shares of Common Stock, the Holder may rely on the number of outstanding shares of Common Stock as reflected in (x) the Company's
most recent Form 10-Q or Form 10-K, as the case may be, (y) a more recent public announcement by the Company or (z) any other notice by the Company
or the Company's Transfer Agent setting forth the number of shares of Common Stock outstanding. Upon the written or oral request of the Holder, the Company shall within two Trading Days confirm orally
and in writing to the Holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Company Common Stock shall be determined after giving effect to the
conversion or exercise of securities of the Company, including this Warrant, by the Holder or its Affiliates since the date as of which such number of outstanding shares of Common Stock was reported.
The Company may assume that the Holder is eligible to exercise any part of this Warrant tendered for exercise without further inquiry. The provisions of this Section 3(c) may be waived by the
Holder upon, at the election of the Holder, not less than 61 days' prior notice to the Company, and the provisions of this Section 3(c) shall continue to apply until such
61st day (or such later date, as determined by the Holder, as may be specified in such notice of waiver). 

        (d)   If,
but only if, at any time after one year from the date of issuance of this Warrant there is no effective Registration Statement registering the resale of the Warrant
Shares by the Holder, this Warrant may also be exercised at such time by means of a "cashless exercise" in which the Holder shall be entitled to receive a certificate for the number of Warrant Shares
equal to the quotient obtained by dividing [(A-B) (X)] by (A), where: 

	 	(A)	 	=	 	the Closing Price on the Trading Day preceding the date of such election;
	 	(B)	 	=	 	the Exercise Price of the Warrants, as adjusted; and
	 	(X)	 	=	 	the number of Warrant Shares issuable upon exercise of the Warrants in accordance with the terms of this Warrant.

        4.    No Fractional Shares or Scrip.    No fractional shares or scrip representing fractional shares shall be issued
upon the exercise of this Warrant. As to any fraction of a share which Holder would otherwise be entitled to purchase upon such exercise, the Company shall pay a cash adjustment in respect of such
final fraction in an amount equal to such fraction multiplied by the Exercise Price. 

        5.    Charges, Taxes and Expenses.    Issuance of certificates for Warrant Shares shall be made without charge to the
Holder for any issue or transfer tax or other incidental expense in respect of the issuance of such certificate, all of which taxes and expenses shall be paid by the Company, and such certificates
shall be issued in the name of the Holder or in such name or names as may be directed by the Holder; provided, however, that in the event certificates
for Warrant Shares are to be issued in a name other than the name of the Holder, this Warrant when surrendered for exercise shall be accompanied by the Assignment Form attached hereto duly executed by
the Holder; and the Company 

3

 

may
require, as a condition thereto, the payment of a sum sufficient to reimburse it for any transfer tax incidental thereto. 

        6.    Closing of Books.    The Company will not close its stockholder books or records in any manner which prevents
the timely exercise of this Warrant, pursuant to the terms hereof. 

        7.    Transfer, Division and Combination.    

        (a)   Subject
to compliance with any applicable securities laws and the conditions set forth in Sections 1 and 7(e) hereof and to the provisions of Section 4.1 of the
Purchase Agreement, this Warrant and all rights hereunder are transferable, in whole or in part, upon surrender of this Warrant at the principal
office of the Company, together with a written assignment of this Warrant substantially in the form attached hereto duly executed by the Holder or its agent or attorney and funds sufficient to pay any
transfer taxes payable upon the making of such transfer. Upon such surrender and, if required, such payment, the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee
or assignees and in the denomination or denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant not so assigned,
and this Warrant shall promptly be cancelled. A Warrant, if properly assigned, may be exercised by a new holder for the purchase of Warrant Shares without having a new Warrant issued. 

        (b)   This
Warrant may be divided or combined with other Warrants upon presentation hereof at the aforesaid office of the Company, together with a written notice specifying
the names and denominations in which new Warrants are to be issued, signed by the Holder or its agent or attorney. Subject to compliance with Section 7(a), as to any transfer which may be
involved in such division or combination, the Company shall execute and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants to be divided or combined in accordance with such
notice. 

        (c)   The
Company shall prepare, issue and deliver at its own expense (other than transfer taxes) the new Warrant or Warrants under this Section 7. 

        (d)   The
Company agrees to maintain, at its aforesaid office, books for the registration and the registration of transfer of the Warrants. 

        (e)   If,
at the time of the surrender of this Warrant in connection with any transfer of this Warrant, the transfer of this Warrant shall not be registered pursuant to an
effective registration statement under the Securities Act and under applicable state securities or blue sky laws, the Company may require, as a condition of allowing such transfer (i) that the
Holder or transferee of this Warrant, as the case may be, furnish to the Company a written opinion of counsel (which opinion shall be in form, substance and scope customary for opinions of counsel in
comparable transactions) to the effect that such transfer may be made without registration under the Securities Act and under applicable state securities or blue sky laws, (ii) that the holder
or transferee execute and deliver to the Company an investment letter in form and substance acceptable to the Company and (iii) that the transferee be an "accredited investor" as defined in
Rule 501(a) promulgated under the Securities Act. 

        8.    No Rights as Shareholder until Exercise.    This Warrant does not entitle the Holder to any voting rights or
other rights as a shareholder of the Company prior to the exercise hereof. Upon the surrender of this Warrant and the payment of the aggregate Exercise Price (or by means of a cashless exercise), the
Warrant Shares so purchased shall be and be deemed to be issued to such Holder as the record owner of such shares as of the close of business on the later of the date of such surrender or payment. 

        9.    Loss, Theft, Destruction or Mutilation of Warrant.    The Company covenants that upon receipt by the Company of
evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of 

4

 

this
Warrant or any stock certificate relating to the Warrant Shares, and in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it (which, in the case of the
Warrant, shall not include the posting of any bond), and upon surrender and cancellation of such Warrant or stock certificate, if mutilated, the Company will make and deliver a new Warrant or stock
certificate of like tenor and dated as of such cancellation, in lieu of such Warrant or stock certificate. 

        10.    Saturdays, Sundays, Holidays, etc.    If the last or appointed day for the taking of any action or the
expiration of any right required or granted herein shall be a Saturday, Sunday or a legal holiday, then such action may be taken or such right may be exercised on the next succeeding day not a
Saturday, Sunday or legal holiday. 

        11.    Adjustments of Exercise Price and Number of Warrant Shares.    The number and kind of securities purchasable
upon the exercise of this Warrant and the Exercise Price shall be subject to adjustment from time to time upon the happening of any of the following. In case the Company shall (i) pay a
dividend in shares of Common Stock or make a distribution in shares of Common Stock to holders of its outstanding Common Stock, (ii) subdivide its outstanding shares of Common Stock into a
greater number of shares, (iii) combine its outstanding shares of Common Stock into a smaller number of shares of Common Stock, or (iv) issue any shares of its capital stock in a
reclassification of the Common Stock, then the number of Warrant Shares purchasable upon exercise of this Warrant immediately prior thereto shall be adjusted so that the Holder shall be entitled to
receive the kind and number of Warrant Shares or other securities of the Company which it would have owned or have been entitled to receive had such Warrant been exercised in advance thereof. Upon
each such adjustment of the kind and number of Warrant Shares or other securities of the Company which are purchasable hereunder, the Holder shall thereafter be entitled to purchase the number of
Warrant Shares or other securities resulting from such adjustment at an Exercise Price per Warrant Share or other security obtained by multiplying the Exercise Price in effect immediately prior to
such adjustment by the number of Warrant Shares purchasable pursuant hereto immediately prior to such adjustment and dividing by the number of Warrant Shares or other securities of the Company
resulting from such adjustment. An adjustment made pursuant to this paragraph shall become effective immediately after the effective date of such event retroactive to the record date, if any, for such
event. 

        12.    Reorganization, Reclassification, Merger, Consolidation or Disposition of Assets.    In case the Company shall
reorganize its capital, reclassify its capital stock, consolidate or merge with or into another corporation (where the Company is not the surviving corporation or where there is a change in or
distribution with respect to the Common Stock of the Company), or sell, transfer or otherwise dispose of all or substantially all its property, assets or business to another corporation and, pursuant
to the terms of such reorganization, reclassification, merger, consolidation or disposition of assets, shares of common stock of the successor or acquiring corporation, or any cash, shares of stock or
other securities or property of any nature whatsoever (including warrants or other subscription or purchase rights) in addition to or in lieu of common stock of the successor or acquiring corporation
("Other Property"), are to be received by or distributed to the holders of Common Stock of the Company, then the Holder shall have the right thereafter
to receive, at the option of the Holder, (a) upon exercise of this Warrant, the number of shares of Common Stock of the successor or acquiring corporation or of the Company, if it is the
surviving corporation, and Other Property receivable upon or as a result of such reorganization, reclassification, merger, consolidation or disposition of assets by a Holder of the number of shares of
Common Stock for which this Warrant is exercisable immediately prior to such event, or (b) cash equal to the value of this Warrant as determined in accordance with the Black-Scholes option
pricing formula. In case of any such reorganization, reclassification, merger, consolidation or disposition of assets, the successor or acquiring corporation (if other than the Company) shall
expressly assume the due and punctual observance and performance of each and every covenant and condition of this Warrant to be performed and observed by the Company and all the obligations and
liabilities hereunder, subject to such modifications as may be deemed appropriate (as 

5

 

determined
in good faith by resolution of the Board of Directors of the Company) in order to provide for adjustments of Warrant Shares for which this Warrant is exercisable which shall be as nearly
equivalent as practicable to the adjustments provided for in this Section 12. For purposes of this Section 12, "common stock of the successor or acquiring corporation" shall include
stock of such corporation of any class which is not preferred as to dividends or assets over any other class of stock of such corporation and which is not subject to redemption and shall also include
any evidences of indebtedness, shares of stock or other securities which are convertible into or exchangeable for any such stock, either immediately or upon the arrival of a specified date or the
happening of a specified event and any warrants or other rights to subscribe for or purchase any such stock. The foregoing provisions of this Section 12 shall similarly apply to successive
reorganizations, reclassifications, mergers, consolidations or disposition of assets. 

        13.    Voluntary Adjustment by the Company.    The Company may at any time during the term of this Warrant reduce the
then current Exercise Price to any amount and for any period of time deemed appropriate by the Board of Directors of the Company. 

        14.    Notice of Adjustment.    Whenever the number of Warrant Shares or number or kind of securities or other
property purchasable upon the exercise of this Warrant or the Exercise Price is adjusted, as herein provided, the Company shall give notice thereof to the Holder, which notice shall state the number
of Warrant Shares (and other securities or property) purchasable upon the exercise of this Warrant and the Exercise Price of such Warrant Shares (and other securities or property) after such
adjustment, setting forth a brief statement of the facts requiring such adjustment and setting forth the computation by which such adjustment was made. 

        15.    Notice of Corporate Action.    If at any time: 

        (a)   the
Company shall take a record of the holders of its Common Stock for the purpose of entitling them to receive a dividend or other distribution, or any right to
subscribe for or purchase any evidences of its indebtedness, any shares of stock of any class or any other securities or property, or to receive any other right, or 

        (b)   there
shall be any capital reorganization of the Company, any reclassification or recapitalization of the capital stock of the Company or any consolidation or merger of
the Company with, or any sale, transfer or other disposition of all or substantially all the property, assets or business of the Company to, another corporation or, 

        (c)   there
shall be a voluntary or involuntary dissolution, liquidation or winding up of the Company; 

then,
in any one or more of such cases, the Company shall give to Holder (i) at least 20 days' prior written notice of the date on which a record date shall be selected for such
dividend, distribution or right or for determining rights to vote in respect of any such reorganization, reclassification, merger, consolidation, sale, transfer, disposition, liquidation or winding
up, and (ii) in the case of any such reorganization, reclassification, merger, consolidation, sale, transfer, disposition, dissolution, liquidation or winding up, at least 20 days' prior
written notice of the date when the same shall take place. Such notice in accordance with the foregoing clause also shall specify (i) the date on which any such record is to be taken for the
purpose of such dividend, distribution or right, the date on which the holders of Common Stock shall be entitled to any such dividend, distribution or right, and the amount and character thereof, and
(ii) the date on which any such reorganization, reclassification, merger, consolidation, sale, transfer, disposition, dissolution, liquidation or winding up is to take place and the time, if
any such time is to be fixed, as of which the holders of Common Stock shall be entitled to exchange their Warrant Shares for securities or other property deliverable upon such disposition,
dissolution, liquidation or winding up. Each such written notice shall be sufficiently given if addressed 

6

 

to
Holder at the last address of Holder appearing on the books of the Company and delivered in accordance with Section 17(d). 

        16.    Authorized Shares.    The Company covenants that during the period the Warrant is outstanding, it will reserve
from its authorized and unissued Common Stock a sufficient number of shares to provide for the issuance of the Warrant Shares upon the exercise of any purchase rights under this Warrant. The Company
further covenants that its issuance of this Warrant shall constitute full authority to its officers who are charged with the duty of executing stock certificates to execute and issue the necessary
certificates for the Warrant Shares upon the exercise of the purchase rights under this Warrant. The Company will take all such reasonable action as may be necessary to assure that such Warrant Shares
may be issued as provided herein without violation of any applicable law or regulation, or of any requirements of the Principal Market upon which the Common Stock may be listed. 

        Except
and to the extent as waived or consented to by the Holder, the Company shall not by any action, including, without limitation, amending its certificate of incorporation or through
any reorganization, transfer of assets, consolidation, merger, 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 this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate to protect the
rights of Holder as set forth in this Warrant against impairment. Without limiting the generality of the foregoing, the Company will (a) not increase the par value of any Warrant Shares above
the amount payable therefor upon such exercise immediately prior to such increase in par value, (b) take all such action as may be necessary or appropriate in order that the Company may validly
and legally issue fully paid and nonassessable Warrant Shares upon the exercise of this Warrant, and (c) use commercially reasonable efforts to obtain all such authorizations, exemptions or
consents from any public regulatory body having jurisdiction thereof as may be necessary to enable the Company to perform its obligations under this Warrant. 

        Before
taking any action which would result in an adjustment in the number of Warrant Shares for which this Warrant is exercisable or in the Exercise Price, the Company shall obtain all
such authorizations or exemptions thereof, or consents thereto, as may be necessary from any public regulatory body or bodies having jurisdiction thereof. 

        17.    Miscellaneous.    

        (a)   Jurisdiction.    This Warrant shall constitute a contract under the laws of New York, without regard to its
conflict of law, principles or rules. 

        (b)   Restrictions.    The Holder acknowledges that the Warrant Shares acquired upon the exercise of this Warrant, if
not registered, will have restrictions upon resale imposed by state and federal securities laws. 

        (c)   Nonwaiver and Expenses.    No course of dealing or any delay or failure to exercise any right hereunder on the
part of Holder shall operate as a waiver of such right or otherwise prejudice Holder's rights, powers or remedies, notwithstanding all rights hereunder terminate on the Termination Date. If the
Company willfully and knowingly fails to comply with any provision of this Warrant, which results in any material damages to the Holder, the Company shall pay to Holder such amounts as shall be
sufficient to cover any costs and expenses including, but not limited to, reasonable attorneys' fees, including those of appellate proceedings, incurred by Holder in collecting any amounts due
pursuant hereto or in otherwise enforcing any of its rights, powers or remedies hereunder. 

        (d)   Notices.    Any notice, request or other document required or permitted to be given or delivered to the Holder
by the Company shall be delivered in accordance with the notice 

7

 

provisions
of the Purchase Agreement; provided upon any permitted assignment of this Warrant, the assignee shall promptly provide the Company with its contact information. 

        (e)   Limitation of Liability.    No provision hereof, in the absence of any affirmative action by Holder to exercise
this Warrant or purchase Warrant Shares, and no enumeration herein of the rights or privileges of Holder, shall give rise to any liability of Holder for the purchase price of any Common Stock or as a
stockholder of the Company, whether such liability is asserted by the Company or by creditors of the Company. 

        (f)    Remedies.    Holder, in addition to being entitled to exercise all rights granted by law, including recovery of
damages, will be entitled to specific performance of its rights under this Warrant. The Company agrees that monetary damages would not be adequate compensation for any loss incurred by reason of a
breach by it of the provisions of this Warrant and hereby agrees to waive the defense in any action for specific performance that a remedy at law would be adequate. 

        (g)   Successors and Assigns.    Subject to applicable securities laws, this Warrant and the rights and obligations
evidenced hereby shall inure to the benefit of and be binding upon the successors of the Company and the successors and permitted assigns of Holder. The provisions of this Warrant are intended to be
for the benefit of all Holders from time to time of this Warrant and shall be enforceable by any such Holder or holder of Warrant Shares. 

        (h)   Amendment.    This Warrant may be modified or amended or the provisions hereof waived with the written consent
of the Company and the Holder. 

        (i)    Severability.    Wherever possible, each provision of this Warrant shall be interpreted in such manner as to be
effective and valid under applicable law, but if any provision of this Warrant shall be prohibited by or invalid under applicable law, such provision shall be ineffective to the extent of such
prohibition or invalidity, without invalidating the remainder of such provisions or the remaining provisions of this Warrant. 

        (j)    Headings.    The headings used in this Warrant are for the convenience of reference only and shall not, for any
purpose, be deemed a part of this Warrant.

        THIS FIRST SUPPLEMENTAL INDENTURE, dated as of April 4, 2002 (the "First Supplemental Indenture"), by and among Sinclair Broadcast
Group, Inc., a Maryland corporation, (hereinafter the "Company"), certain of the Company's subsidiaries identified as Guarantors on the signature pages hereof (collectively, the "Existing
Guarantors") and each of the Company's subsidiary identified as New Guarantors on the signature pages hereof (individually, a "New Guarantor" and collectively, the "New Guarantors"), and First Union
National Bank, as Trustee under the Indenture, as hereinafter defined (hereinafter the "Trustee"). 

        WHEREAS, the Company, certain Existing Guarantors and the Trustee are parties to an Indenture dated as of December 10, 2001 (the
"Existing Indenture") pursuant to which the Company issued its 83/4% Senior Subordinated Notes due 2011 (hereinafter the "Notes"). All capitalized terms used in this First Supplemental
Indenture and not otherwise defined shall be assigned the meaning ascribed to them in the Existing Indenture. 

        WHEREAS, the Existing Indenture provides that, without the consent of any Holders, the Company and the Existing Guarantors, when
authorized by a Board Resolution, and the Trustee, at any time and from time to time, may enter into indentures supplemental thereto or agreements or other instruments with respect to any Guarantee,
in form and substance satisfactory to the Trustee, for the purpose of adding a Guarantor pursuant to the requirements of Section 1014 therein. 

        WHEREAS, each New Guarantor wishes to guarantee the Notes pursuant to Section 1014(b) of the Indenture. 

        WHEREAS, pursuant to the Existing Indenture the Company, the Existing Guarantors, the New Guarantors and the Trustee have agreed to enter
into this First Supplemental Indenture for the purposes stated herein; and 

        WHEREAS, all things necessary have been done to make this First Supplemental Indenture, when executed and delivered by the Company, the
Existing Guarantors, and the New Guarantors, the legal, valid and binding agreement of the Company, the Existing Guarantors, and each New Guarantor, in accordance with its terms. 

        NOW, THEREFORE, THIS FIRST SUPPLEMENTAL INDENTURE WITNESSETH:

        The
parties hereto mutually covenant and agree as follows: 

Section I

        Section 1.01.    Pursuant
to Section 1014(b) of the Existing Indenture, as of the date of this First Supplemental Indenture, each New Guarantor shall be deemed to
be a Restricted Subsidiary of the Company and a Guarantor of the Notes and hereby executes and delivers this First Supplemental Indenture to evidence its guarantee of the Notes on the same terms as
the guarantee (the "Senior Guarantee") of the indebtedness (the "Senior Indebtedness") associated with the Credit Agreement dated as of May 28, 1998, by and among the Company and certain of its
subsidiaries and The Chase Manhattan Bank, as Agent for the Lenders which are parties thereto, as amended and restated by the Amendment and Restatement dated as of May 9, 2001, as further
amended by Amendment No. 1 dated as of October 30, 2001, and as amended and supplemented from time to time (the "Credit Agreement"), as hereinafter set forth and further provided that
said guarantee of the Notes by each New Guarantor shall be subordinated to the Senior Guarantee to the same extent as the Notes are subordinated to the Senior Indebtedness pursuant to the Existing
Indenture. 

Section II

        Section 2.01.    Guarantee.    Each New Guarantor hereby agrees to guarantee the Existing Indenture and the
Notes related thereto pursuant to the terms and conditions of Article Fourteen of 

 

the
Existing Indenture, such Article Fourteen being incorporated by reference herein as if set forth at length herein. 

        Section 2.02.    Rights of Contribution.    For the purposes of this Section 2.02 Existing Guarantors
and each New Guarantor shall be individually referred to as "Guarantor" and collectively, as "Guarantors." The Guarantors hereby agree, as between themselves, that if any Guarantor (an
"Excess Funding Guarantor") shall pay Indenture Obligations in excess of the Excess Funding Guarantor's Pro Rata Share (as hereinafter defined) of such
Indenture Obligations, the other Guarantors shall, on demand (but subject to the next sentence hereof), pay to the Excess Funding Guarantor an amount equal to their respective Pro Rata Share of such
Excess Funding Guarantor's payment. The payment obligation of any Guarantor to any Excess Funding Guarantor under this Section 2.02 shall be subordinate and subject in right of payment to the
prior payment in full of the obligations of such Guarantor under the other provisions of this Section II and such Excess Funding Guarantor shall not exercise any right or remedy with respect to
such excess until payment and satisfaction in full of all of such obligations. For the purposes hereof, "Pro Rata Share" shall mean, for any Guarantor,
a percentage equal to the percentage of such Guarantor's Net Assets as of the Valuation Date (as defined in the next sentence) of the aggregate Net Assets of all of the Guarantors as at such date. For
purposes of the preceding sentence, the "Valuation Date" shall mean the date hereof; provided that, if the Trustee requests from time to time that the
Guarantors ratify and confirm their respective obligations under this Section II, they shall promptly do so pursuant to an instrument reasonably satisfactory to the Trustee and the Valuation
Date shall mean the date of the latest such ratification and confirmation to occur at the request of the Trustee after the date hereof, and "Net Assets"
shall mean with respect to any Guarantor as at any date, an amount equal to the excess of the fair salable value of the assets of such Guarantor at such date (without taking into account the rights of
such Guarantor under Section 3.08 of the Credit Agreement), and excluding the value of the shares of the stock or other equity interest owned by such Guarantor and any other Guarantor party to
this Indenture, on such date over the amount that would be required to pay the probable liabilities of such Guarantor determined as of such date (excluding the obligations of such Guarantor under
Section 3 of the Credit Agreement) on all of its debts. 

Section III

        Section 3.01.    This
First Supplemental Indenture shall be construed as supplemental to the Existing Indenture and shall form a part thereof, and the Existing
Indenture is hereby incorporated by reference herein and, as supplemented hereby and is hereby ratified, approved and confirmed. 

        Section 3.02.    This
First Supplemental Indenture may be signed in any number of counterparts, all of which taken together shall constitute one and the same instrument.
This First Supplemental Indenture shall be governed by and construed in accordance with the laws of the State of New York. 

        Section 3.03.    This
First Supplemental Indenture shall be effective and operative on the date and time hereof. 

        IN WITNESS WHEREOF, the parties hereto have caused this First Supplemental Indenture to be duly executed, and their respective corporate
seals to be hereunto affixed and attested, all as of the day and year above written.
