                        WARRANT TO PURCHASE COMMON STOCK

                                       OF

                               DIGIRAD CORPORATION

                                                Date of Issuance - June 16, 2004

                            Void after June 16, 2008

         Digirad Corporation, a Delaware corporation (the "COMPANY"), hereby
certifies that, for value received _________________ (including any successors
and assigns, the "HOLDER"), is entitled, subject to the terms set forth below,
to purchase from the Company at any time or from time to time, before 5:00 PM,
Pacific time on June 16, 2008 (the "EXPIRATION DATE") up to ___________ shares
of Common Stock of the Company (the "WARRANT SHARES"), subject to adjustment as
provided herein. The purchase price per share of such Common Stock upon exercise
of this Warrant shall be $12.00 (the "EXERCISE PRICE"), subject to adjustment as
provided herein. This Warrant is issued to the Holder in connection with and
subject to the terms and conditions of that certain Loan Modification and
Warrant Issuance Agreement dated May 7, 2004, by and among the Company, Holder
and/or his assignor and the other parties thereto (the "LOAN MODIFICATION
AGREEMENT").

         1. EXERCISE PERIOD. Subject to Section 2.2 herein, this Warrant may be
exercised by the Holder at any time or from time to time after the Date of
Issuance noted above but before 5:00 PM, Pacific time on the Expiration Date
(the "EXERCISE PERIOD").

         2. EXERCISE OF WARRANT; NUMBER OF WARRANT SHARES; TERMINATION.

             2.1 EXERCISE OF WARRANT; PARTIAL EXERCISE. This Warrant may be
exercised in full or in part by the Holder with respect to any or all of the
Warrant Shares by surrender of this Warrant, together with the form of
subscription attached hereto as SCHEDULE 1, duly executed by the Holder, to the
Company at its principal office, accompanied by payment, in cash or by certified
or official bank check payable to the order of the Company, of the aggregate
Exercise Price for the Warrant Shares to be purchased hereunder. For any partial
exercise hereof, the Holder shall designate in a notice of exercise or net issue
election notice that number of shares of Common Stock that he wishes to
purchase. On any such partial exercise, the Company at its expense shall
forthwith issue and deliver to the Holder a new warrant of like tenor, in the
name of the Holder, which shall be exercisable for such number of shares of
Common Stock represented by this Warrant which have not been purchased upon such
exercise.





             2.2 TERMINATION OF THE WARRANT UPON A CORPORATE TRANSACTION.
Immediately following the occurrence of a Corporate Transaction, this Warrant
shall terminate and cease to be outstanding, provided that written notice has
been given to the Holder at least 20 days prior to the occurrence of the
Corporate Transaction. For the purposes of this Warrant, a "Corporate
Transaction" shall mean: (i) a merger or consolidation in which securities
possessing more than fifty percent (50%) of the total combined voting power of
the Company's outstanding securities are transferred to a person or persons
different from the persons holding those securities immediately prior to such
transaction; or (ii) the sale, transfer or other disposition of all or
substantially all of the Company's assets in complete liquidation or dissolution
of the Company.

         3. NET ISSUANCE.

3.1 RIGHT TO CONVERT. The Holder shall have the right to convert this Warrant or
any portion thereof (the "CONVERSION RIGHT") into shares of Common Stock as
provided in this Section 3 at any time or from time to time during the Exercise
Period. Upon exercise of the Conversion Right with respect to a particular
number of Warrant Shares (the "CONVERTED WARRANT SHARES"), the Company shall
deliver to the Holder (without payment by the Holder of any exercise price or
any cash or other consideration) that number of shares of fully paid and
nonassessable shares of Common Stock computed using the following formula:

         X = Y (A - B)
             ---------
                 A

         Where       X =   the number of shares of Common Stock to be delivered
                           to the Holder

                     Y =   the number of Converted Warrant Shares

                     A =   the fair market value of one share of the Company's
                           Common Stock on the Conversion Date (as defined
                           below)

                     B =   the Exercise Price (as adjusted through the
                           Conversion Date)

The Conversion Right may only be exercised with respect to a whole number of
Warrant Shares. No fractional shares shall be issuable upon exercise of the
Conversion Right, and if the number of shares to be issued determined in
accordance with the foregoing formula is other than a whole number, the Company
shall pay to the Holder an amount in cash equal to the fair market value of the
resulting fractional share on the Conversion Date (as defined below). Shares
issued pursuant to the Conversion Right shall be treated as if they were issued
upon the exercise of this Warrant.

             3.2 METHOD OF EXERCISE. The Conversion Right may be exercised by
the Holder by the surrender of this Warrant at the principal office of the
Company together with a written statement specifying that the Holder thereby
intends to exercise the Conversion Right and indicating the total number of
shares under this Warrant that the Holder is exercising through the Conversion
Right. Such conversion shall be effective upon receipt by the Company of this
Warrant together with the aforesaid written statement, or on such later date as
is specified therein (the "CONVERSION DATE") and at such time the person in
whose name any certificate for shares of Common Stock shall be issuable upon
such exercise shall be deemed to be the record holder of such Common Stock for
all purposes. Certificates for the shares issuable upon exercise of the
Conversion Right and, if applicable, a new warrant evidencing the balance of the
shares remaining subject to the Warrant, shall be issued as of the Conversion
Date and shall be delivered to the Holder promptly following the Conversion
Date.


                                       2


             3.3 DETERMINATION OF FAIR MARKET VALUE. For purposes of this
Section 3, fair market value of a share of Common Stock on the Conversion Date
shall mean:

                  (1) If traded on a stock exchange, the fair market value of
the Common Stock shall be deemed to be the average of the closing selling prices
of the Common Stock on the stock exchange determined by the Board of Directors
of the Company (the "BOARD") to be the primary market for the Common Stock over
the ten (10) trading day period (or such shorter period immediately following
the closing of the Company's initial public offering) ending on the date prior
to the Conversion Date, as such prices are officially quoted in the composite
tape of transactions on such exchange;

                  (2) If traded over-the-counter, the fair market value of the
Common Stock shall be deemed to be the average of the closing bid prices (or, if
such information is available, the closing selling prices) of the Common Stock
over the ten (10) trading day period (or such shorter period immediately
following the closing of the Company's initial public offering) ending on the
date prior to the Conversion Date, as such prices are reported by the National
Association of Securities Dealers through its NASDAQ system or any successor
system; and

                  (3) If there is no public market for the Common Stock, the
fair market value of the Common Stock shall be determined in good faith by the
Board.

         4. WHEN EXERCISE EFFECTIVE. The exercise of this Warrant pursuant to
Section 2 shall be deemed to have been effected immediately prior to the close
of business on the business day on which this Warrant is surrendered to the
Company as provided in Section 2.1, or on such later date as is specified in the
form of subscription, and at such time the person in whose name any certificate
for shares of Common Stock shall be issuable upon such exercise, as provided in
Section 5, shall be deemed to be the record holder of such Common Stock for all
purposes.

         5. DELIVERY ON EXERCISE. As soon as practicable after the exercise of
this Warrant in full or in part pursuant to Section 2, 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, or as the Holder may
direct, a certificate or certificates for the number of fully paid and
nonassessable full shares of Common Stock to which the Holder shall be entitled
on such exercise, together with cash, in lieu of any fraction of a share, equal
to such fraction of the current market value of one full share of Common Stock
as determined pursuant to Section 3.3.

         6. ADJUSTMENTS. The number and kind of shares of Common Stock (or any
shares of stock or other securities which may be) issuable upon the exercise of
this Warrant and the Exercise Price shall be subject to adjustment from time to
time upon the happening of certain events, as follows:


                                       3


             6.1 DIVIDENDS, DISTRIBUTIONS, STOCK SPLITS OR COMBINATIONS. If the
Company shall at any time or from time to time after the date hereof (a) make or
issue, or fix a record date for the determination of holders of Common Stock (or
any shares of stock or other securities which may be issuable upon the exercise
of this Warrant) entitled to receive, a dividend or other distribution payable
in additional shares of common or preferred stock (as the case may be), (b)
subdivide its outstanding shares of Common Stock (or any shares of stock or
other securities which may be issuable upon the exercise of this Warrant) into a
larger number of shares of Common Stock (or any shares of stock or other
securities which may be issuable upon the exercise of this Warrant) or (c)
combine its outstanding shares of Common Stock (or any shares of stock or other
securities which may be issuable upon the exercise of this Warrant) into a
smaller number of shares of Common Stock (or any shares of stock or other
securities which may be issuable upon the exercise of this Warrant), then and in
each such event the Exercise Price then in effect and the number of shares
issuable upon exercise of this Warrant shall be appropriately adjusted.

             6.2 RECLASSIFICATION OR REORGANIZATION. If the Common Stock (or any
shares of stock or other securities which may be) issuable upon the exercise of
this Warrant shall be changed into the same or different number of shares of any
class or classes of stock, whether by capital reorganization, reclassification
or otherwise (other than a subdivision or combination of shares or stock
dividend provided for in Section 6.1 above, or pursuant to a Corporate
Transaction), then and in each such event the Holder shall be entitled to
receive upon the exercise of this Warrant the kind and amount of shares of stock
and other securities and property receivable upon such reorganization,
reclassification or other change to which a holder of the number of shares of
Common Stock (or any shares of stock or other securities which may be) issuable
upon the exercise of this Warrant would have received if this Warrant had been
exercised immediately prior to such reorganization, reclassification or other
change, all subject to further adjustment as provided herein.

             6.3 NOTICE OF ADJUSTMENTS AND RECORD DATES. The Company shall
promptly notify the Holder in writing of each adjustment or readjustment of the
Exercise Price and the number of shares of Common Stock (or any shares of stock
or other securities which may be) issuable upon the exercise of this Warrant.
Such notice shall state the adjustment or readjustment and show in reasonable
detail the facts on which that adjustment or readjustment is based. In the event
of any taking by the Company of a record of the holders of Common Stock (or any
shares of stock or other securities which may be issuable upon the exercise of
this Warrant) for the purpose of determining the holders thereof who are
entitled to receive any dividend or other distribution, the Company shall notify
Holder in writing of such record date at least twenty (20) days prior to the
date specified therein.

             6.4 WHEN ADJUSTMENTS TO BE MADE. No adjustment in the Exercise
Price shall be required by this Section 6 if such adjustment either by itself or
with other adjustments not previously made would require an increase or decrease
of less than one percent (1%) in such price. Any adjustment representing a
change of less than such minimum amount which is postponed shall be carried
forward and made as soon as such adjustment, together with other adjustments
required by this Section 6 and not previously made, would result in a minimum
adjustment. Notwithstanding the foregoing, any adjustment carried forward shall
be made no later than ten (10) business days prior to the Expiration Date. All
calculations under this Section 6.4 shall be made to the nearest cent. 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.


                                       4


             6.5 CERTAIN OTHER EVENTS. If any change in the outstanding Common
Stock (or any shares of stock or other securities which may be issuable upon the
exercise of this Warrant) or any other event occurs as to which the other
provisions of this Section 6 are not strictly applicable or if strictly
applicable would not fairly protect the purchase rights of the Holder of the
Warrant in accordance with such provisions, then the Board shall make an
adjustment in the number and class of shares available under this Warrant, the
Exercise Price or the application of such provisions, so as to protect such
purchase rights as aforesaid. The adjustment shall be such as will give the
Holder, upon exercise of this Warrant, the same aggregate Exercise Price and the
same total number, class and kind of shares as the Holder would have owned had
this Warrant been exercised prior to the event and had the Holder continued to
hold such shares until after the event requiring adjustment.

         7. REPLACEMENT OF WARRANTS. On receipt by the Company of evidence
reasonably satisfactory to the Company of the loss, theft, destruction or
mutilation of this Warrant and, in the case of any such loss, theft or
destruction of this Warrant, on delivery of an indemnity agreement reasonably
satisfactory in form and amount to the Company or, in the case of any such
mutilation, on surrender and cancellation of such Warrant, the Company at its
expense will execute and deliver to the Holder, in lieu thereof, a new warrant
of like tenor.

         8. NO RIGHTS OR LIABILITY AS A STOCKHOLDER. This Warrant does not
entitle the Holder hereof to any voting rights or other rights as a stockholder
of the Company. No provisions hereof, in the absence of affirmative action by
the Holder to purchase Common Stock, and no enumeration herein of the rights or
privileges of the Holder, shall give rise to any liability of the Holder as a
stockholder of the Company.

         9. REPRESENTATIONS OF HOLDER.

         The Holder hereby represents, covenants and acknowledges to the Company
that:

             (1) this Warrant and the Warrant Shares are "restricted securities"
as such term is used in the rules and regulations under the Securities Act of
1933, as amended (the "ACT") and that this Warrant and the Warrant Shares have
not been registered under the Act and the Company has no present intention of
registering the Securities under the Act or any state securities law, and that
this Warrant and the Warrant Shares must be held indefinitely unless a transfer
can be made pursuant to appropriate exemptions (including, without limitation,
pursuant to Rule 144 under the Act);

             (2) the Holder has read, and fully understands, the terms of this
Warrant set forth on its face and the attachments hereto, including the
restrictions on transfer contained herein;


                                       5


             (3) the Holder is purchasing for investment for his own account and
not with a view to or for sale in connection with any distribution of this
Warrant or the Warrant Shares and he has no intention of selling such securities
in a public distribution in violation of the federal securities laws or any
applicable state securities laws; and

             (4) the Holder (i) has received all information the Holder has
requested from the Company and considers necessary or appropriate for deciding
whether to acquire this Warrant and the Warrant Shares, (ii) has had an
opportunity to ask questions and receive answers from the Company regarding the
terms and conditions of this Warrant and the Warrant Shares and to obtain any
additional information necessary to verify the accuracy of the information given
to the Holder, and (iii) has such knowledge and experience in financial and
business matters such that the Holder is capable of evaluating the merits and
risks of the investment in this Warrant and the Warrant Shares.

         10. MARKET STAND-OFF AGREEMENT. The Holder hereby agrees that, during
the period of duration specified by the Company and an underwriter of Common
Stock or other securities of the Company, following the effective date of a
registration statement of the Company filed under the Act, he shall not, to the
extent requested by the Company and such underwriter, directly or indirectly
sell, offer to sell, contract to sell (including, without limitation, any short
sale), grant any option to purchase or otherwise transfer or dispose of (other
than to donees who agree to be similarly bound) any securities of the Company
held by it at any time during such period except Common Stock included in such
registration; provided, however, that:

             (1) Such agreement shall not exceed 180 days for the first such
registration statement of the Company which covers Common Stock (or other
securities) to be sold on its behalf to the public in an underwritten offering;

             (2) Such agreement shall not exceed ninety (90) days for any
subsequent registration statement of the Company which covers Common Stock (or
other securities) to be sold on its behalf to the public in an underwritten
offering; and

             (3) All directors and officers of the Company as well as all
holders of one percent (1%) or more of the Company's outstanding capital stock
are similarly bound.

         In order to enforce the foregoing covenant, the Company may impose
stop-transfer instructions with respect to securities held by the Holder (and
the shares or securities of every other person subject to the foregoing
restriction) until the end of such period.

         11. MISCELLANEOUS.

             11.1 TRANSFER OF WARRANT. This Warrant shall not be transferable or
assignable by the Holder without the express written consent of the Company;
provided, however, that one hundred eighty (180) days after the Date of Issuance
the Holder may transfer or assign this Warrant, without the Company's written
consent, to any recipient of least 5,714 of the Warrant Shares (as adjusted for
any stock split, combination, reclassification or reorganization) who agrees in
writing to be bound by the provisions of this Warrant.


                                       6


             11.2 NOTICES. Any notice required or permitted under this Warrant
shall be in writing and shall be hand delivered, sent by facsimile or other
electronic medium, by registered or certified mail, postage prepaid, or by
nationally recognized overnight carrier to the Company or to the Holder at the

normal business hours of the recipient (if not sent during the normal business
hours of the recipient, then on the next business day), (iii) if sent by mail,

overnight courier, one day after deposit with such courier.

             11.3 ATTORNEYS' FEES. If any action at law or in equity is
necessary to enforce or interpret the terms of this Warrant, the prevailing
party shall be entitled to reasonable attorneys' fees, costs and disbursements
in addition to any other relief to which such party may be entitled.

             11.4 AMENDMENTS AND WAIVERS. Any term of this Warrant may be
amended and the observance of any other term of this Warrant may be waived
(either generally or in a particular instance and either retroactively or
prospectively), only with the written consent of the Company and holders of
Warrants representing at least a majority of the aggregate number of Warrant
Shares issuable upon exercise of all outstanding Warrants issued pursuant to the
Loan Modification Agreement. Any amendment or waiver effected in accordance with
this paragraph shall be binding upon the Company, the Holder and the holders of
all Warrants issued pursuant to the Loan Modification Agreement.

             11.5 SEVERABILITY. If one or more provisions of this Warrant are
held to be unenforceable under applicable law, such provision shall be excluded
from this Warrant and the balance of the Warrant shall be interpreted as if such
provision were so excluded and shall be enforceable in accordance with its
terms.

             11.6 GOVERNING LAW. This Warrant shall be governed by and construed
and enforced in accordance with the laws of the State of California as applied
to agreements among California residents entered into and to be performed
