(the "Carlyle Entities") an aggregate of 1,849,625 shares of Common Stock as
payment of accrued and unpaid dividends on the shares of Series B Convertible
Preferred Stock, par value $.01 per share (the "Preferred Stock"), held by the
Carlyle Entities.


CUSIP No. 82655N105                    13D                   Page 6 of 29 Pages

         Also pursuant to the Purchase Agreement and as of December 31, 2002,
the Carlyle Entities converted all shares of Preferred Stock held by them into
an aggregate of 3,243,900 shares of Common Stock.

         Also pursuant to the Purchase Agreement, the Carlyle Entities and SRC
agreed to the cancellation of certain warrants (being referred to as Class I
(Mirror) Warrants) representing an obligation to purchase an aggregate of 62,884
shares of Common Stock.

         Excalibur purchased the additional shares (i) for the purpose of
investment and (ii) to provide to SRC a portion of the funds required by SRC in
connection with the Sixth Loan Modification Agreement (described below).

         On December 31, 2002, CadleRock Joint Venture L.P. ("CadleRock")
purchased from the holder thereof indebtedness of SRC having a face amount of
$7,120,000. In connection with such purchase, SRC entered into a Sixth Loan
Modification Agreement (the "Modification Agreement") with CadleRock. Pursuant
to the Modification Agreement, (i) SRC paid to CadleRock $1,560,000 and (ii)
CadleRock agreed to the reduction to $2,000,000 of the balance of the
indebtedness owing by SRC. The $2,000,000 is payable June 30, 2004 and bears
interest at the rate of 12% per annum. A $200,000 termination fee is payable by
SRC to CadleRock at the time of payment of the $2,000,000.

         A portion of the $2,500,000 received by SRC in consideration of the
shares issued in the Private Placement was used to fund the $1,560,000 payment
to CadleRock.

         The Purchase Agreement provides that, for a period of three years, the
Board of Directors of SRC shall take such action as may be consistent with its
fiduciary duties to cause the Board of Directors to remain consistent with its
current composition, subject to the following: (i) Mr. Tabacchi (a director of
SRC and an affiliate of Excalibur) and one representative of the Carlyle
Entities will be members of the Board; (ii) Mr. Marco Brustio (who was elected
to the Board on December 31, 2002 and who is an affiliate of La Sesta S.A.) will
be a member of the Board; and (iii) the Board shall nominate an additional
director who shall have significant financial and accounting expertise and who
is neither employed by SRC nor any affiliate of SRC as an employee or
consultant, and the identity and financial and accounting experience of such
director shall be reasonably satisfactory to the Carlyle Entities; and (iv) Mr.
Tabacchi shall have the right to designate a director to fill the first vacancy
on the Board (other than vacancies related to the positions reserved for the
Carlyle Entities and Mr. Brustio).

         On December 31, 2002, Mr. Tabacchi, La Sesta S.A., and the Carlyle
Entities entered into a Put and Right of First Refusal Agreement (the "Put
Agreement"). Under the Put Agreement, the Carlyle Entities were granted the
right to require Mr. Tabacchi and La Sesta or their permitted assigns to
purchase from the Carlyle Entities an aggregate of up to 7,000,000 shares of
Common Stock of SRC at the purchase price, in the amounts, during the periods
and on the terms set forth in the Put Agreement. Of the 7,000,000 shares, Mr.
Tabacchi (and his permitted assigns) may be required to purchase up to 5,600,000
shares (subject to the further limitation that the aggregate purchase price
shall not exceed $4,000,000), and La Sesta (and its


CUSIP No. 82655N105                    13D                   Page 7 of 29 Pages

permitted assigns) may be required to purchase up to 1,400,000 shares (subject
to the further limitation that the aggregate purchase price shall not exceed
$1,000,000).

         The Put Agreement also grants to Mr. Tabacchi and La Sesta certain
rights to purchase shares that the Carlyle Entities propose to sell to a third
party. The terms under which Mr. Tabacchi and La Sesta may purchase such shares
are to be no less favorable than those offered by the third party purchaser.

ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER.

23.8% of all shares outstanding. Excalibur and Mr. Tabacchi share voting and

                                   PUT RIGHTS

        SECTION 2.01 Grant of Put Rights.

Subject to the terms and conditions of this Agreement, Tabacchi and La Sesta,
and each of their Permitted Grantor Transferees, irrevocably grants and issues
to each Grantee a Put Option to require the Grantors to purchase the Shares, in
whole or in part, exercisable in such Grantee's sole discretion, during the Put
Period, at the Put Price, in the following proportions: (a) one-third or
2,333,333 Shares for the First Put Period; (b) one-third or 2,333,333 Shares for
the Second Put Period, and (c) one-third or 2,333,333 Shares for the Third Put
Period (and with the First Put Period and Second Put Period, sometimes referred
to individually, as a "Put Period" and collectively, as the "Put Periods"). By
way of clarification and not limitation, the Grantees may exercise the Put
Option as of the last Business Day of any given quarter within a Put Period for
as many Shares as it may determine subject to the above maximums (for example,
the Grantees may, but are not required to, exercise the Put Option for the
entire 2,333,333 Shares for the First Put Period, in the first quarter). If at
the last day of the First Put Period, Second Put Period or Third Put Period, as
the case may be, Grantees have not exercised the Put Option with respect to any
of the Shares allocable to such Put Period, the Grantees' right to exercise the
Put Option and to require the Grantors to purchase such Shares shall expire,
subject to the Grantees' right, in the event of a Standoff, to carry-over any
Shares to the remaining quarters of the Put Term, as

                                        5


CUSIP No. 82655N105                    13D                   Page 14 of 29 Pages

described in Section 2.02 below. The Grantors obligations to acquire Shares
shall be up to the following maximum amounts: (a) Tabacchi and his Permitted
Grantor Transferees shall be obligated to purchase and acquire up to an
aggregate of 5,600,000 Shares, except that Tabacchi and his Permitted Grantor
Transferees shall not be required to purchase such shares at any Put Closing (as
hereafter defined) if the aggregate purchase price for all Shares purchased by
Tabacchi and its Permitted Grantor Transferees would then exceed $4,000,000, and
(b) La Sesta and its Permitted Grantor Transferees shall be obligated to acquire
up to an aggregate of 1,400,000 Shares except that La Sesta and its Permitted
Grantor Transferees shall not be required to purchase such shares at any Put
Closing if the aggregate purchase price for all Shares purchased by La Sesta and
its Permitted Grantor Transferees would then exceed $1,000,000. The Grantors
shall have no rights or interests in any Shares that are not purchased and paid
for by them.

        SECTION 2.02 Put Period and Standoff.

The Put Option shall continue in effect during the Put Term and all Extensions
thereof, except that if as of the last day of any quarter during the Put Period
the index for the national market of the Nasdaq Stock Market, Inc. ("Nasdaq") or
any successor thereto, as reported by Nasdaq, has increased (i) by 60% or more
during the prior six-month period as reported for the first day of such
six-month period and the last day of such six-month period, or (ii) by 120% or
more during the prior 12 month period as reported for the first day of such
12--month period and the last day of such 12-month period (collectively, the
"Standoff Conditions"), the Put Option relating to such quarter shall not be
exercisable by any Grantee (each case being a "Standoff"). If a Standoff shall
be in effect at the end of the First Put Period, Second Put Period or Third Put
Period, as the case may be, the Grantees shall carry-over any unexercised Shares
(the "Carry-Over Shares") allocable to such Put Period, by reallocating those
Carry-Over Shares on a pro-rata basis to the remaining Put Periods during the
Put Term; provided, that if any Standoff is in effect as of the end of the Third
Put Period, the Put Term shall be extended by successive full quarters (each an
"Extension" and together the "Extensions") until such time as such Standoff
Conditions shall be no longer in effect. Following each Standoff, the Put Option
shall resume being exercisable by the Grantees on each date that the Standoff
shall no longer be in effect. In the final quarter of an Extension, the Grantees
shall have the right to exercise the Put Option, and, if so exercised, the
Grantors shall have the obligation to purchase, all remaining Shares that have
not yet been purchased by the Grantors.

        SECTION 2.03 Put Notice.

The Put Option may be exercised in the sole discretion of each Grantee by
delivering written notice ("Put Notice") of exercise to the Grantor as of the
last day of each quarter within a Put Period. The Put Notice shall indicate the
number of Shares each Grantee is putting to the Grantors. Upon receipt of a Put
Notice in accordance with the terms hereof, the applicable Grantees shall be
obligated to sell all of the Shares to which the Put Notice relates, free and
clear of all liens and encumbrances created by each of them or their respective
Affiliates (other than pursuant to this Agreement). The Grantors shall be
obligated to purchase pro rata all of such Shares put by the applicable
Grantees, at the applicable Put Price in accordance with, and subject to, the
terms of this Agreement; provided, however, that the Put Option may not be
exercised if

                                        6


CUSIP No. 82655N105                    13D                   Page 15 of 29 Pages

the Standoff Conditions have occurred and are continuing. For purposes of the
foregoing sentence, the "pro rata" portion of Shares that Tabacchi and its
Permitted Grantor Transferees on the one hand, and La Sesta and its Permitted
Grantor Transferees on the other hand, shall be obligated to purchase, shall
mean a fraction, (A) the numeration of which shall be 5,600,000 in the case of
Tabacchi and his Permitted Grantor Transferees, and 1,400,000 in the case of La
Sesta and its Permitted Grantor Transferees and the (B) denominator of which
shall be 7,000,000, subject to the aggregate limitations set forth in Section
2.01 of this Agreement.

        SECTION 2.04 Put Price; Closing and Limitation on Shares.

                (a) The "Put Price" at which the Put Shares shall be sold to the
Grantors shall be the Fair Market Value determined as of the last day of each
quarter for which the Put Option has been exercised. Notwithstanding anything
herein to the contrary, the Put Price shall not (a) exceed $1.00 per share, and
(b) be less than $0.20 per share, provided, further, that the Put Price at which
the first 2,333,333 Shares sold to and purchased by the Grantors during the last
five quarters of the Put Term shall be not less than $0.30 per share.

                (b) The Grantees shall be obligated to sell, and the Grantors
shall be obligated to pay the purchase price for and acquire, the Shares being
sold and purchased pursuant to each Put Notice at the Put Closing (as hereafter
defined). The closing of the purchase and sale of Shares pursuant to each Put
Option, shall take place at the principal office of Carlyle or at such other
location as the Parties shall mutually agree, on a Business Day to be mutually
agreed upon by the Grantors and the Grantees, which date shall be no later than
30 days following the last day of the quarter during which the Put Notice was
delivered, or if the Parties do not mutually agree to a closing date, the
closing date shall be the next Business Day following such thirtieth day (each a
"Put Closing"); provided, however, that if the purchase of Shares is subject to
prior regulatory approval, the Grantors and Grantees will use their reasonable
best efforts to obtain the necessary regulatory approvals and the Put Closing
shall be postponed until the expiration of five Business Days after the date
that all such regulatory approvals shall have been received. At each Put
Closing, the Grantees shall deliver to the Grantors the certificates
representing the Shares being sold pursuant to the exercise of such Put Option,
duly endorsed or accompanied by stock powers executed in blank, in form and
substance customary in the United States of America for transactions of this
type, and evidence reasonably satisfactory to the Grantor that the Shares are
being transferred free and clear of all liens and encumbrances created by such
Grantee or its Affiliates (it being understood that in no event shall a Grantee
be obligated to make any representations and warranties, or to provide any
indemnities, with respect to (i) any matters relating to the Company, or (ii)
with respect to any other matters other than (1) title to the Shares held by
such Grantee, such title being free and clear of all liens and encumbrances
created by it or its Affiliates, (2) such Grantee's authority, authorization and
right to enter into and consummate the sale without contravention of any law or
agreement, and without the need for any third party consent or approval (not
including any governmental or regulatory consent or approval which shall have
been applied for or received), and (3) the existence of pending or, to the
knowledge of the Grantee, threatened litigation involving such Grantee that
could reasonably be expected to prohibit or limit the sale of good title to the
Shares by such Grantee). At each Put Closing, the Grantors shall pay the Put
Price to each Grantee by delivery of cash by wire transfer to the accounts of
the applicable Grantees.

                (c) Notwithstanding anything in Section 2.04(b) to the contrary,
if Grantees exercise their Put Option (including Excess Exercised Shares, as
defined below, if any, carried over from the previous quarter) for more than an
aggregate of 777,777 Shares as of the last day of a quarter that is not the last
day of the First Put Period, Second Put Period or Third Put Period, or any
Extension thereof, as the case may be, the Put Closing and payment of the Put
Price for such number of Shares in excess of 777,777 (the "Excess Exercised
Shares") shall take place at a date not later than 30 days following the first
to occur of (i) the end of the next quarter during which Put Notices exercising
the Put Option for fewer than an aggregate of 777,777 Shares (including Excess
Exercised Shares) have been delivered to the Grantors, or (ii) the end of the
next quarter that shall be the last quarter of a Put Period, it being understood
that no payment shall be required to be made for more than 777,777 Shares for
any quarter in any Put Period, except for the last quarter in each Put Period at
which time the Grantors shall be obligated to purchase all Excess Exercised
Shares from the Grantees.

                (d) If any of the Grantors do not pay the full amount of the Put
Price for all Shares to be purchased by such Grantors at any Put Closing or
during the Put Period, Article III, Right of First Refusal, immediately shall
terminate and no longer be in effect, and, at the Grantees' option, in their
sole discretion, the Grantees may (i) withdraw the exercise of the Put Option
with respect to such Shares, in which case they would retain all rights and
obligations with respect thereto, (ii) deem the exercise of the Put Option to
remain in effect, in which case, if the Grantors do not pay the Put Price within
30 days of the date of the Put Notice, the Put Price shall double, and (iii)
exercise all of their other rights and remedies, in law and in equity, pursuant
to this Agreement and otherwise. The Grantors and Grantees acknowledge and agree
that this Section 2.05 does not constitute a liquidated damages provision or a
penalty.

        SECTION 2.05 Assignment.

Tabacchi and La Sesta may assign their respective rights and obligations to
purchase the Shares pursuant to the Put Option to their respective Permitted
Grantor Transferees. Notwithstanding an assignment of the Put Option by Tabacchi
or La Sesta, as the case may be, Tabacchi and La Sesta shall remain primarily
liable for all payment and performance obligations of the Grantors under the Put
Option and this Agreement.

        SECTION 2.06 Exercise of Put Option Not a Transfer.

None of the exercises by Grantees of the Put Option, nor the consummation of the
transactions contemplated thereby, shall constitute a Transfer that is subject
to the Right of First Refusal set forth in Article III of this Agreement (by way
of example and not limitation, the sale of shares by a Grantee pursuant to the
Put Option to a Permitted Grantor Transferee, shall not require any Grantee to
comply with the Right of First Refusal provisions of Article III).

                             RIGHT OF FIRST REFUSAL

        SECTION 3.01 Right of First Refusal.

CUSIP No. 82655N105                    13D                   Page 17 of 29 Pages

                (a) During the Put Period, prior to selling any Shares to a
third party, Carlyle agrees that upon receipt of a bona fide written binding
offer (subject only to this Right of First Refusal) from a third party (the
"Proposed Transferee"), Carlyle shall submit a written offer (the "Offer") to
sell all Shares proposed to be purchased by the Proposed Transferee (the
"Offered Shares"), on terms and conditions, including price, not less favorable
than those on which Carlyle proposes to sell such Offered Shares to the Proposed
Transferee, to Tabacchi and La Sesta (the "Offerees").

                (b) The rights of each Offeree shall be in addition to and not
in substitution of its rights and obligations under the Put Option.

                (c) The Offer shall disclose the number of Offered Shares
proposed to be sold, the terms and conditions (including price) of the proposed
sale, and any other material facts relating to the proposed sale. The Offer
shall further state that the Offerees may acquire, in accordance with the
provisions of this Agreement, the Offered Shares for the price and upon the
other terms and conditions set forth therein.

        SECTION 3.02 Notice of Intent to Purchase.

If the Offerees exercise their right to acquire the Offered Shares, such right
may only be exercised to acquire all such Offered Shares and not a portion of
such Offered Shares. If the Offerees desire to purchase the Offered Shares
offered to them, they shall communicate in writing their election to purchase
all the Offered Shares (the "Right of First Refusal Exercise Notice") to Carlyle
no later than 20 days after the date of the Offer (the parties providing such
Right of First Refusal Exercise Notice, are sometimes referred to hereafter
individually, as a "Purchaser," and collectively as, the "Purchasers"). If an
Offeree declines to purchase, or otherwise defaults and fails to purchase, any
Offered Shares, in order for the remaining Offerees to have the right to acquire
Offered Shares, such remaining Offerees shall be required to acquire the
declining Offeree's allotment of Offered Shares (the "Over-Allotment Right"), in
whole and not in part, and such Offerees shall provide written notice to Carlyle
specifying the number of additional Offered Shares it will acquire pursuant to
the Over-Allotment Right. Such Right of First Refusal Exercise Notice shall,
when taken in conjunction with the Offer, be deemed to constitute a valid,
binding and enforceable agreement for the sale and purchase of the Offered
Shares.

        SECTION 3.03 Offered Shares Closing.

The closing of the purchase and sale of Offered Shares pursuant to the Offer,
shall take place no later than 30 days following the date of the Right of First
Refusal Exercise Notice at the principal office of Carlyle or at such other
location as the Parties shall mutually agree, on a Business Day to be mutually
agreed to by Carlyle and the Purchasers or if the Parties do not mutually agree
to a closing date, the closing date shall be the next Business Day following
such fifteenth day (the "Offered Shares Closing"), provided that if the purchase
of Offered Shares is subject to prior regulatory approval, Carlyle and the
Purchasers will use their reasonable best efforts to obtain the necessary
regulatory approvals and the Offered Shares Closing shall be postponed until the

                                        9


CUSIP No. 82655N105                    13D                   Page 18 of 29 Pages

expiration of five Business Days after the date that all such regulatory
approvals shall have been received, except that if such regulatory approvals are
not received within 60 days following the date of the Right of First Refusal
Exercise Notice, Carlyle shall have the right to sell the Offered Shares
pursuant to Section 3.04 below. At the Offered Shares Closing, Carlyle shall
deliver to the Purchasers the certificates representing the Offered Shares duly
endorsed or accompanied by stock powers executed in blank, in form and substance
customary in the United States of America for transactions of this type to the
Purchasers, and evidence reasonably satisfactory to the Purchasers that the
Offered Shares are being transferred free and clear of all liens and
encumbrances created by Carlyle or its Affiliates (it being understood that in
no event shall a Grantee be obligated to make any representations and
warranties, or to provide any indemnities, with respect to (i) any matters
relating to the Company, or (ii) with respect to any other matters other than
(1) title to the Shares held by such Grantee, such title being free and clear of
all liens and encumbrances created by it or its Affiliates, (2) such Grantee's
authority, authorization and right to enter into and consummate the sale without
contravention of any law or agreement, and without the need for any third party
consent or approval (not including any governmental or regulatory consent or
approval which shall have been applied for or received), and (3) the existence
of pending or, to the knowledge of the Grantee, threatened litigation involving
such Grantee that could reasonably be expected to prohibit or limit the sale of
good title to the Shares by such Grantee). At the Offered Shares Closing, the
Purchasers shall pay the purchase price for the Offered Shares to Carlyle in
such amount and on such payment terms as set forth in the Offer.

        SECTION 3.04 Sale to Third Party.

If the Purchasers do not exercise this Right of First Refusal in whole, or do
not offer to purchase all of the Offered Shares, the Offered Shares may be sold
by Carlyle at any time within three months after the date the Offer was made.
Any such sale shall be to the Proposed Transferee on terms and conditions not
materially different than those specified in the Offer. If any Offered Shares
are not sold within the three month period or if the terms of the Offer shall
change, the Offered Shares shall be subject to renewed compliance with the
requirements of the Right of First Refusal pursuant to Section 3.01. Any third
party to whom Shares are sold shall have no rights or obligations under this
Agreement. None of the provisions of this Article III shall be applicable to,
nor shall prohibit, the offer and sale of any Offered Shares in open market
transactions on any exchange, market system or bulletin board on which shares of
Common Stock are quoted, or offers and sales of the Shares can be made, from
time to time, and pursuant to the exercise of registration rights under the
Registration Rights Agreements with the Company to which the Grantees are party
covering Shares.

                                   ARTICLE IV

                                  MISCELLANEOUS

        SECTION 4.01 Publicity.

To the extent that any of he Parties intends to issue any press release or make

performance of this Agreement, the transactions contemplated hereby, and the
ongoing business relationship between the Parties,

                                       10

which release, announcement or disclosure mentions any other Parties to this
Agreement, the Party making the disclosure shall consult with each of the
Parties so named in such disclosure; provided, however, that no Party shall be
restrained, after consultation with the other Parties, to the extent such
consultation is feasible, from making such disclosure as it shall be required to
make by applicable law or by applicable regulations of any regulatory body or
securities exchange.

        SECTION 4.02 Equitable Relief.

The Parties hereto acknowledge and agree that it will be impossible to measure
the damages that would be suffered if any Party fails to comply with the
provisions of this Agreement that it is required to comply with and, in the
event of any such failure, the non-breaching Parties will have the right to
obtain specific performance of the breaching Party's obligations under this
Agreement and to obtain immediate injunctive relief. These rights shall be in
addition to, and not in substitution of, any other rights that any non-breaching
Party may have in law or in equity. Tabacchi, La Sesta and their Permitted
Grantor Transferees on the one hand, and Carlyle on the other hand, agree that
the rights, powers and remedies given to each other Party by this Agreement are
cumulative and concurrent and not exclusive of any thereof or of any other
powers, rights or remedies available to such Party, whether existing at law or
in equity of by statute or otherwise, and shall be in addition to every other
right, power or remedy provided in this Agreement, and the exercise or beginning
of the exercise by such Party of any one or more of such rights, powers and
remedies shall not preclude the simultaneous or later exercise by such Party of
any or all such other rights, powers and remedies. No failure on the part of any
Party to exercise any right, power or remedy shall operate as a waiver thereof.

        SECTION 4.03 Entire Agreement.

Each Party expressly acknowledges and agrees that this Agreement is the final
expression of the Parties agreement, and supercedes all prior and
contemporaneous agreements and understandings, both oral and written, including
the Term Sheet dated November 27, 2002, by and among the Parties, with respect
to the subject matter hereof. Except as set forth in this Agreement, the Parties
hereto acknowledge that they are not Parties to, and have no knowledge of, any
agreements or understandings, both oral and written, to act in concert or as a
group (including, without limitation, as a group within the meaning of

act together, with respect to SRC or its securities.

        SECTION 4.04 Binding Effect; Benefit.
