                                     WARRANT
                            TO PURCHASE COMMON STOCK
                                       OF
                          AMPERSAND MEDICAL CORPORATION


Warrant No. 6 CC                 250,000 Shares                    July 26, 2001

     AMPERSAND MEDICAL CORPORATION, a Delaware corporation (the "Company"), for
value received, hereby certifies that Cadmus Corporation, or its registered
assigns, is entitled to purchase from the Company 250,000 duly authorized,
validly issued, fully paid and non-assessable shares of Common Stock, par value
$0.001 per share, of the Company ("Common Stock", subject to the adjustments, if
any, provided for in Section 2), at the purchase price of US$1.00 per share
(such per share price, subject to the adjustments, if any provided for in
Section 2, being hereinafter referred to as the "Exercise Price") at any time or
from time to time after the Issue Date and prior to 5:00 p.m., New York City
time, on the Expiration Date, all subject to the terms, conditions and
adjustments set forth below in this Warrant.

     This Warrant (this "Warrant") is (or is a part of) the Warrant to Purchase
Common Stock of the Company, similar in all respects except as to number of
shares purchasable, names of holders and dates (collectively, the "Warrants")
issued by the Company on the Original Issue, together with its $100,000
principal amount Promissory Note dated the Original Issue Date payable to the
order of Cadmus Corporation.

     Certain terms used and not defined above in this Warrant are defined in
Section 5.

1.  EXERCISE OF WARRANT

     1.1. MANNER OF EXERCISE. This Warrant may be exercised by the holder
hereof, in whole or in any part (including as to any fraction of a share),
during normal business hours on any Business Day until the Expiration Date by
surrender of this Warrant, with the form of Subscription Notice at the end
hereof (or a reasonable facsimile thereof) duly executed by such holder, to the
Company, accompanied by: (i) payment of the aggregate Exercise Price for the
Common Stock being purchased. Payment of the Exercise Price shall be made, at
the option of the holder hereof, either: (A) in cash or by certified or official
bank check payable to the order of the Company in the amount of the aggregate
Exercise Price (or portion thereof being paid in this manner), (B) by the
surrender of indebtedness of the Company (principal and/or interest) in an
amount equal to the aggregate Exercise Price (or portion thereof being paid in
this manner), (C) by the surrender of Common Stock, including Common Stock
obtained upon any previous exercise of this Warrant, having a Market Value (as
hereinafter defined) as of the date of exercise equal to the aggregate Exercise
Price (or portion thereof being paid in this manner), (D) by the surrender of
other warrants of the Company, having a Warrant Value (as hereinafter defined)
as of the date of exercise equal to the aggregate Exercise Price (or portion
thereof being paid in this manner), or (E) by any combination of the foregoing.
In lieu of paying the Exercise Price in the foregoing manner, the holder hereof
may, at its option, surrender to the Company all or a specified portion of this
Warrant in exchange for a number of shares of Common Stock determined by
dividing (1) the product of (i) the number of shares issuable upon exercise of
this Warrant or such specified portion (as the case may be) and (ii) the
difference between the Market Value of the Common Stock as of the date of
exercise AND THE EXERCISE PRICE, by (2) such Market Value. For purposes of the
foregoing,


<PAGE>   2
                                                                               2

"Market Value" of the Common Stock means, as of any date, the
reported closing sale price per share of the Common Stock as of the immediately
preceding Business Day (provided there is no such reported closing sale price on
such Business Day, then the average of the last-reported bid and ask prices on
such Business Day); and "Warrant Value" means, for any warrant as of any date,
the excess (if any) of the exercise price per share thereof over the Market
Value of the Common Stock as of such date.

     1.2. WHEN EXERCISE EFFECTIVE. Each exercise of this Warrant shall be deemed
to have been effected immediately prior to the close of business on the Business
Day on which this Warrant shall have been exercised as provided in Section 1.1,
and immediately prior to the close of business on such Business Day the Person
or Persons in whose name or names any certificate or certificates for Common
Stock shall be issuable upon such exercise as provided in Section 1.3 shall be
deemed to have become the holder or holders of record thereof.

     1.3. DELIVERY OF STOCK CERTIFICATES, ETC. As soon as practicable after the
exercise of this Warrant in whole or in any part as provided in Section 1.1, and
in any event within ten (10) days thereafter, the Company at its expense
(including the payment by it of any applicable issue taxes) will cause to be
issued in the name of and delivered to the holder hereof or, subject to Section
3, such other Person or Persons as such holder (upon payment by such holder of
any applicable transfer taxes) may direct: (i) a certificate or certificates for
the number of shares of Common Stock to which such holder shall be entitled upon
such exercise; (ii) in case such exercise is in part only, a new Warrant or
Warrants of like tenor, calling in the aggregate on the face or faces thereof
for the number of shares of Common Stock equal to (without giving effect to any
adjustment therein from the Original Issue Date) the number of such shares
called for on the face of this Warrant minus the number of shares of Common
Stock (without giving effect to any adjustment therein from the Issue Date) as
to which this Warrant shall have been so exercised.

2.  ANTI-DILUTION ADJUSTMENTS.

     (1) Stock Splits, Stock Dividends, Combinations. If at any time after the
Original Issue Date the Company shall:

               (A) take a record of the holders of its Common Stock for the
     purpose of entitling them to receive a dividend payable in, or other
     distribution of, Additional Shares of Common Stock,

               (B) subdivide its outstanding shares of Common Stock into a
     larger number of shares of Common Stock, or

               (C) combine its outstanding shares of Common Stock into a smaller
     number of shares of Common Stock

then: (i) the number of shares of Common Stock issuable upon exercise of the
Warrants shall be adjusted to equal the number of shares of Common Stock which a
holder of the same number of shares of Common Stock issuable upon exercise of
the Warrants immediately prior to the occurrence of such event would own or be
entitled to receive after the occurrence of such event; and (ii) the Exercise
Price shall be adjusted to equal the product of such Exercise Price in effect
immediately prior to such adjustment and a fraction (x) the numerator of which
shall be the number of shares of Common Stock issuable upon exercise of the
Warrants immediately prior to the adjustment made pursuant to the foregoing
clause (i) and (y) the denominator shall be the number of shares of Common Stock
issuable upon exercise of the Warrants immediately after such adjustment.

     (2) Issuance of Additional Shares of Common Stock. If at any time after the
Original Issue Date the Company shall issue or sell any Additional Shares of
Common Stock to any Person or Persons for consideration in an amount per
Additional Share of Common Stock less than the Exercise Price at the date the
Additional Shares of Common Stock are issued, then: (i) the number of shares of
Common Stock issuable upon exercise of the Warrants shall be adjusted to equal
the product of (A) the number of shares of Common Stock issuable upon exercise
of the Warrants immediately prior to the occurrence of such issuance or sale,
and (B) a fraction (x) the numerator of which shall be the number of shares of
Common Stock Outstanding immediately prior the occurrence of such issuance or
sale plus the number of Additional Shares of Common Stock to be issued in such
issuance or sale and (y) the denominator of which shall be the number of shares
of Common Stock Outstanding immediately prior to the occurrence of such issuance
or sale plus the number of shares of Common Stock which the aggregate
consideration to be paid for such Additional Shares of Common Stock would
purchase at the Exercise Price at the date such shares


<PAGE>   3
                                                                               3

are issued or sold (prior to adjustment hereunder); and (ii) the Exercise Price
shall be adjusted to equal the product of such Exercise Price in effect
immediately prior to such adjustment and a fraction (x) the numerator of which
shall be the number of shares of Common Stock issuable upon exercise of the
Warrants immediately prior to the adjustment made pursuant to the foregoing
clause (i) and (y) the denominator shall be the number of shares of Common Stock
issuable upon exercise of the Warrants immediately after such adjustment.

     (3) Issuance of Convertible Securities. If at any time after the Original
Issue Date the Company shall take a record of the holders of its Common Stock
for the purpose of entitling them to receive a distribution of, or shall
otherwise issue or sell, any Convertible Securities, whether or not the rights
to convert, exchange or exercise thereunder are immediately exercisable, then
the number of shares of Common Stock issuable upon exercise of the Warrants
shall be adjusted as provided in Section 2(2) on the basis that the maximum
number of Additional Shares of Common Stock issuable to effect the conversion,
exchange or exercise of all such Convertible Securities shall be deemed to have
been issued and outstanding and the Company shall have received all of the
consideration payable therefor, if any, as of the date of the actual issuance of
such Convertible Securities. After adjustment shall have been made in the number
of shares of the Common Stock issuable upon exercise of the Warrants and the
Exercise Price with respect to the distribution, issuance or sale of any
Convertible Securities ("Primary Convertible Securities") in accordance with the
foregoing, no further adjustment thereof shall be made upon the actual issuance
of (x) any Convertible Securities ("Secondary Convertible Securities") issued
upon conversion, exchange or exercise of such Primary Convertible Securities or
(y) any shares of Common Stock issued upon conversion, exchange or exercise of
such Primary Convertible Securities or Secondary Convertible Securities.

     (4) Superseding Adjustments. If, at any time any adjustment of the number
of shares of Common Stock issuable upon exercise of the Warrants shall have been
made pursuant to subsection 2(3) as the result of any issuance of Convertible
Securities,

               (A) the right of conversion, exchange or exercise with respect to
     all or a portion of such Convertible Securities shall have expired, shall
     not have been exercised or shall be treated as having been cancelled or
     acquired by the Company, or

               (B) the consideration per share of Common Stock issuable pursuant
     to the terms of such Convertible Securities shall be increased or
     decreased, or the number of shares of Common Stock issuable pursuant to
     such terms shall be increased or decreased, solely by virtue of provisions
     therein contained for an automatic decrease in such consideration per
     share, or automatic increase in such number of shares, upon the occurrence
     of a specified date or event,

then (i) such previous adjustment shall be rescinded and annulled and the
Additional Shares of Common Stock which were deemed to have been issued by
virtue of the computation made in connection with the adjustment so rescinded
and annulled shall no longer be deemed to have been issued by virtue of such
computation, and (ii) a recomputation shall be made of the effect of such
Convertible Securities on the basis of

               (C) treating the number of Additional Shares of Common Stock or
     other property (if any) theretofore actually issued or issuable pursuant to
     any previous conversion, exchange or exercise (as the case may be) of any
     such Convertible Securities as having been issued on the date or dates of
     any such conversion, exchange or exercise and for the consideration
     actually received and receivable therefor, and

               (D) treating any such Convertible Securities which then remain
     outstanding as having been granted or issued immediately after the time of
     such increase or decrease (as the case may be)

whereupon a new adjustment of the number of shares of Common Stock issuable upon
exercise of the Warrants, and of the Exercise Price, shall be made on the basis
pursuant to the appropriate provisions of this Section 2, which new adjustment
shall supersede the previous adjustment so rescinded and annulled.

     (5) Other Provisions Applicable to Adjustments Under this Section. The
following provisions shall be applicable to the making of adjustments provided
for in this Section 2:

          (A) Computation of Consideration. To the extent that any Additional
Shares of Common Stock or any Convertible Securities shall be issued for cash
consideration, the consideration received by the



<PAGE>   4
                                                                               4

Company therefor shall be the amount of the cash received by the Company
therefor, or, if such Additional Shares of Common Stock or Convertible
Securities are offered by the Company for subscription, the subscription price,
or, if such Additional Shares of Common Stock or Convertible Securities are sold
to underwriters or dealers for public offering without a subscription offering,
the initial public offering price (in any such case subtracting any amounts paid
or receivable for accrued interest or accrued dividends and without taking into
account any compensation, discounts or expenses paid or incurred by the Company
for and in the underwriting of, or otherwise in connection with, the issuance
thereof). To the extent that such issuance shall be for a consideration other
than cash, then, except as herein otherwise expressly provided herein, the
amount of such consideration shall be deemed to be the fair value of such
consideration at the time of such issuance as determined by resolution of the
Board of Directors. In case any Additional Shares of Common Stock or any
Convertible Securities shall be issued in connection with any transaction
described in Section 2(6) in which the Company issues any securities or other
property, the amount of consideration therefor shall be deemed to be the fair
value, as determined by resolution of the Board of Directors, of such portion of
the assets and business of the non-surviving Person as such Board by resolution
shall determine to be attributable to such Additional Shares of Common Stock or
Convertible Securities, as the case may be. The consideration for any Additional
Shares of Common Stock issuable pursuant to conversion, exchange or exercise of
any Convertible Securities shall be the consideration received by the Company
for issuing such Convertible Securities plus the additional consideration (if
any) payable to the Company upon the conversion, exchange or exercise of such
Convertible Securities. In case of the issuance at any time of any Additional
Shares of Common Stock or Convertible Securities in payment or satisfaction of
any dividends upon any class of stock other than Common Stock, the Company shall
be deemed to have received for such Additional Shares of Common Stock or
Convertible Securities a consideration equal to the amount of such dividend so
paid or satisfied.

          (B) When Adjustments to be Made. The adjustments required by this
Section 2 shall be made whenever and as often as any specified event requiring
an adjustment shall occur, except that any adjustment of the number of shares of
Common Stock into which the Notes are convertible that would otherwise be
required may be postponed (except in the case of a subdivision or combination of
shares of the Common Stock, as provided for in subsection 2.(1)) up to, but not
beyond the date of, conversion if such adjustment either by itself or with other
adjustments not previously made adds or subtracts less than 1% of the shares of
Common Stock issuable upon exercise of the Warrants immediately prior to the
making of such adjustment. Any adjustment representing a change of less than
such minimum amount (except as aforesaid) which is postponed shall be carried
forward and made as soon as such adjustment, together with other adjustments
required by this Section 2 and not previously made, would result in a minimum
adjustment or on the date of conversion. For the purpose of any adjustment, any
specified event shall be deemed to have occurred at the close of business on the
date of its occurrence.

          (C) Fractional Interests. In computing adjustments under this Section
2, fractional interests in Common Stock shall be taken into account to the
nearest one-ten thousandth (1/10,000th) of a share.

          (D) When Adjustment Not Required. If the Company shall take a record
of the holders of its Common Stock for the purpose of entitling them to receive
a dividend or distribution or subscription or purchase rights and shall,
thereafter and before the distribution to stockholders, legally abandon its plan
to pay or deliver such dividend, distribution, subscription or purchase rights,
then thereafter no adjustment shall be required by reason of the taking of such
record and any such adjustment previously made in respect thereof shall be
rescinded and annulled.

     (6) Reorganization, Reclassification, Merger, Consolidation or Disposition
of Assets. In the event that the Company, at any time after the Original Issue
Date, shall (i) merge or consolidate with any other Person and the Company shall
not be the resulting or surviving Person, (ii) merge or consolidate with any
other Person and the Company shall be the resulting or surviving Person but in
connection therewith the Common Stock shall be changed into or exchanged for
stock or other securities of any other Person or cash or any other property or
assets, (iii) sell, lease or otherwise transfer all or substantially all of its
property or assets to any other Person and in connection therewith stock or
other securities, cash or any other property or assets shall be issuable or
deliverable in exchange for the Common Stock, or (iv) effect a capital
reorganization or reclassification of the Common Stock (other than in the
circumstances where any of Sections 2(1), (2) or (3) apply), then, and as a
condition to the effectiveness of any such merger consolidation, sale, lease or
other transfer or capital reorganization or reclassification (as the case may
be), lawful and adequate provision shall be made so that the holders of the
Warrants shall thereafter be entitled to receive, upon exercise thereof (in lieu
of the Common Stock which such holders would have been entitled to receive upon
such exercise immediately prior to such merger, consolidation, sale, lease or
other transfer or capital reorganization or reclassification (as the case may
be)), the stock or other securities, cash or other property or assets which such
holders would have been entitled to receive had the outstanding Warrants been
exercised immediately prior to such merger, consolidation, sale, lease or other
transfer or capital


<PAGE>   5

                                                                               5

reorganization or reclassification (as the case may be), at the aggregate
Exercise Price in effect immediately prior to the such merger, consolidation,
sale, lease or other transfer or capital reorganization or reclassification (as
the case may be). As a further condition to the effectiveness of any such
merger, consolidation, sale, lease or other transfer or capital reorganization
or reclassification (as the case may be), any Person (other than the Company)
who shall become obligated to deliver any stock or other securities, cash or
other property or assets in accordance with the foregoing shall deliver to the
holders of the Warrants a written instrument by which such Person shall
expressly agree to issue and deliver any such stock or other securities, cash or
other property or assets upon exercise of the Warrants.

     (7) Certain Limitations. Notwithstanding anything herein to the contrary,
the Company shall not enter into any transaction which, by reason of any
adjustment hereunder, would cause the Exercise Price to be less than the par
value per share of Common Stock.

     (8) Notice of Exercise Price Adjustments. Whenever the number of shares of
Common Stock issuable upon exercise of the Warrants, or the Exercise Price,
shall be adjusted pursuant to this Section 2, the Company shall forthwith
prepare a certificate to be executed by an authorized officer of the Company
setting forth, in reasonable detail, the event requiring the adjustment and the
method by which such adjustment was calculated, specifying the number of shares
of Common Stock into which the outstanding Warrants are exercisable and (if such
adjustment was made pursuant to Section 2(6), describing the number and kind of)
any stock or other securities, cash or other property or assets for which the
outstanding Warrants are exercisable, and any change in the Exercise Price
thereof, after giving effect to such adjustment or change. The Company shall
promptly cause a signed copy of such certificate to be delivered to each holder
of Warrants at such holder's address as appears on the books of the Company. The
Company shall keep at its office copies of all such certificates and cause the
same to be available for inspection at said office during normal business hours
by any holder of Warrants or any prospective purchaser of Warrants from such
holder.

     (9) Notice of Certain Corporate Actions. Holders of Warrants all be
entitled to the same rights to receive notices of corporate actions and other
matters pertaining to the Company as the holders of outstanding shares of Common
Stock, and the Company shall forward (or cause to be forwarded) to each holder
of Warrants, at such holder's address as appears on the books of the Company,
all notices forwarded to holders of the Common Stock generally (whether or not
legally required).

contained in this Warrant shall be determined to be invalid, unenforceable or
illegal in any respect for any reason, the validity, enforceability or legality
of such provision in any other respect and the remaining provisions of this
Warrant shall not, at the election of the party for whom the benefit of the
provision exists, be in any way impaired.
