7. Conditions of the Obligations of the Purchasers.  The obligations of the
several Purchasers to purchase and pay for the Offered Securities will be
subject to the accuracy of the representations and warranties on the part of the
Company herein, to the accuracy of the statements of officers of the Company
made pursuant to the provisions hereof, to the performance, in all material
respects, by the Company of its obligations hereunder and to the following
additional conditions precedent:

included in the Preliminary Offering Circular and the Final Offering Circular
comply as to form in all material respects with the applicable accounting
requirements of the Securities Act and the related published Rules and
Regulations.

(b) The Purchasers shall have also received a letter, dated the date of this
Agreement, of Ernst & Young LLP confirming that they are independent public
accountants within the meaning of the Securities Act and the applicable
published Rules and Regulations and to the effect that:

(i)  in their opinion the financial statements examined by them and included in
the Preliminary Offering Circular and the Final Offering Circular comply as to
form in all material respects with the applicable accounting requirements of the
Securities Act and the related published Rules and Regulations;

Certified Public Accountants for a review of interim financial information as
described in Statement of Auditing Standards No. 100, Interim Financial
Information, on the unaudited financial statements included in the Preliminary
Offering Circular and the Final Offering Circular;

(iii) on the basis of the review referred to in clause (ii) above, a reading of
the latest available interim financial statements of TD Group, inquiries of
officials of TD Group who have responsibility for financial and accounting
matters and other specified procedures, nothing came to their attention that
caused them to believe that:

(A)  (x) the unaudited financial statements included in the Preliminary Offering
Circular and the Final Offering Circular do not comply as to form in all
material respects with the applicable accounting requirements of the Securities
Act and the related published Rules and Regulations or (y) any material
modifications should be made to such unaudited financial statements for them to
be in conformity with GAAP;

 (B) the unaudited consolidated net sales, net operating income and net income
amounts for the 26-week periods ended April 1, 2006 and April 2, 2005 included
in the Preliminary Offering Circular and the Final Offering Circular do not
agree with the amounts set forth in the unaudited consolidated financial
statements for those same periods or were not determined on a basis
substantially consistent with that of the corresponding amounts in the audited
statements of income;

(C) at the date of the latest available balance sheet read by such accountants,
or at a subsequent specified date not more than three business days prior to the
date of this Agreement, (i) there was any change in the capital stock or any
increase in short-term indebtedness or long-term debt of TD Group and its
consolidated subsidiaries or, at the date of the latest available balance sheet
read by such accountants, there was any decrease in consolidated net current
assets or net assets, as compared with amounts shown on the latest balance sheet
included in the Final Offering Circular; or

(D) for the period from the closing date of the latest income statement included
in the Final Offering Circular to the closing date of the latest available
income statement read by such accountants there were any decreases, as compared
with the corresponding period of the previous year and with the period of
corresponding length ended the date of the latest income statement included in
the Final Offering Circular, in consolidated net sales, net operating income, or
in the ratio of earnings to fixed charges;

except in all cases set forth in clauses (B), (C) and (D) above for changes,
increases or decreases which are described in such letter; and

(iv) they have compared specified dollar amounts (or percentages derived from
such dollar amounts) and other financial information contained in the
Preliminary Offering Circular, each other document comprising any part of the
General Disclosure Package, the Final Offering Circular and each item of
Supplemental Marketing Material (in each case to the extent that such dollar
amounts, percentages and other financial information are derived from the
general accounting records of TD Group and its subsidiaries subject to the
internal

11

--------------------------------------------------------------------------------

controls of TD Group’s accounting system or are derived directly from such
records by analysis or computation) with the results obtained from inquiries, a
reading of such general accounting records and other procedures specified in
such letter and have found such dollar amounts, percentages and other financial
information to be in agreement with such results, except as otherwise specified
in such letter.

(c)  Subsequent to the execution and delivery of this Agreement, there shall not
have occurred (i) any change, or any development or event involving a
prospective change, in the condition (financial or other), business, properties
or results of operations of the Company and its subsidiaries taken as one
enterprise which, in the judgment of Banc of America and Credit Suisse, is
material and adverse and makes it impractical or inadvisable to proceed with
completion of the offering or the sale of and payment for the Offered
Securities; (ii) any downgrading in the rating of any debt securities of the
Company by any “nationally recognized statistical rating organization” (as
defined for purposes of Rule 436(g) under the Securities Act), or any public
announcement that any such organization has under surveillance or review its
rating of any debt securities of the Company (other than an announcement with
positive implications of a possible upgrading, and no implication of a possible
downgrading, of such rating) or any announcement that the Company has been
placed on negative outlook, except in each case for any of the foregoing
relating solely to any 8 3/8% Senior Subordinated Notes that are not tendered in
connection with the Tender Offer; (iii) any change in U.S. or international
financial, political or economic conditions or currency exchange rates or
exchange controls as would, in the reasonable judgment of Banc of America and
Credit Suisse, be likely to prejudice materially the success of the proposed
issue, sale or distribution of the Offered Securities, whether in the primary
market or in respect of dealings in the secondary market; (iv) any material
suspension or material limitation of trading in securities generally on the New
York Stock Exchange, or any setting of minimum prices for trading on such
exchange; (v) any suspension of trading of any securities of TD Group on any
exchange or in the over-the-counter market; (vi) any banking moratorium declared
by U.S. Federal or New York authorities; (vii) any major disruption of
settlements of securities or clearance services in the United States; (viii) any
attack on, outbreak or escalation of hostilities or act of terrorism involving
the United States or, any declaration of war by Congress or any other national
or international calamity or emergency if, in the reasonable judgment of Banc of
America and Credit Suisse, the effect of any such attack, outbreak, escalation,
act, declaration, calamity or emergency makes it impractical or inadvisable to
proceed with completion of the offering or sale of and payment for the Offered
Securities.

(d)  The Purchasers shall have received an opinion, dated the Closing Date, of
Willkie Farr & Gallagher LLP, Baker & Hostetler LLP or other local counsel to

(iv)               No consent, approval, authorization or order of, or filing
with, any governmental agency or body or any court is required to be obtained or

required under state securities or blue sky laws except for the order of the
Commission declaring effective the Exchange Offer Registration Statement or, if

reasonably be expected to have a Material Adverse Effect;

(v) To our knowledge, except as set forth in the General Disclosure Package,
there are no pending actions, suits or proceedings against the Company, TD
Group, any of their subsidiaries or any of their respective properties in any
New York or Federal court that, would individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect, or which are otherwise
material in the context of the sale of the Offered Securities;

(vi)               The execution, delivery and performance of the Indenture,
this Agreement and the Registration Rights Agreement, the consummation of the
transactions herein contemplated and the issuance and sale of the Offered
Securities will not result in a breach or violation of any of the terms and
provisions of, or constitute a default under, (1) any Federal or New York
statute or any rule, regulation or order, in each case known to such counsel to
be customarily applicable to transactions of the type contemplated by this
Agreement or, to such counsel’s knowledge, any order, judgment or decree
specifically naming the Company or any of its subsidiaries of any governmental

(3) the charter or by-laws of the Company or any such subsidiary, except in the
case of clauses (1) and (2), for breaches, violations and defaults that would
not, individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect, and the Company has full power and authority to enter into this
Agreement and to consummate the transactions contemplated hereby;

13

--------------------------------------------------------------------------------

(vii)              Such counsel have no reason to believe that the Final
Offering Circular, or any amendment or supplement thereto, as of the date hereof
and as of the Closing Date, contained any untrue statement of a material fact or
omitted to state any material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading; such counsel have no reason to believe that the documents
specified in a schedule to such counsel’s letter, consisting of those included

Closing Date, when considered together with the information set forth in the
schedules to this Agreement, contained any untrue statement of a material fact
or omitted to state any material fact required to be stated therein or necessary

were made, not misleading; it being understood that such counsel need express no

transfer, reorganization, moratorium and similar laws of general applicability
relating to or affecting creditors’ rights and to general equity principles and
(2) any rights to indemnity or contribution thereunder may be limited by federal
and state securities laws and public policy considerations

(ix)                It is not necessary in connection with (i) the offer, sale

Purchasers in the manner contemplated by this Agreement, to register the Offered
Securities under the Securities Act or to qualify an indenture in respect
thereof under the Trust Indenture Act.

(e)  The Purchasers shall have received from Latham & Watkins LLP, counsel for
the Purchasers, such opinion or opinions, dated the Closing Date, with respect
to the incorporation of the Company, the validity of the Offered Securities, the
Final Offering Circular and the General Disclosure Package, the exemption from

they request for the purpose of enabling them to pass upon such matters.

(f)     The Purchasers shall have received a certificate, dated the Closing
Date, of the Chief Executive Officer, the President or any Vice President and a
principal financial or accounting officer of the Company in which such officers,
to the best of their knowledge after reasonable investigation, shall state that
the representations and warranties of the Company in this Agreement are true and

14

8. Indemnification and Contribution. (a)  The Company and the Guarantors will,
jointly and severally, indemnify and hold harmless each Purchaser, its officers,
partners, members, directors and its affiliates and each person, if any, who
controls such Purchaser within the meaning of Section 15 of the Securities Act,
against any losses, claims, damages or liabilities, joint or several, to which
such Purchaser may become subject, under the Securities Act or the Exchange Act
or otherwise, insofar as such losses, claims, damages or liabilities (or actions
in respect thereof) arise out of or are based upon any untrue statement or
alleged untrue statement of any material fact contained in the Preliminary
Offering Circular or the Final Offering Circular, in each case as amended or
supplemented, or any Issuer Free Writing Communication, or arise out of or are
based upon the omission or alleged omission to state therein a material fact
necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading and will reimburse each
Purchaser for any legal or other expenses reasonably incurred by such Purchaser
in connection with investigating or defending any such loss, claim, damage,
liability or action as such expenses are incurred; provided, however, that
neither the Company nor the Guarantors will not be liable in any such case to
the extent that any such loss, claim, damage or liability arises out of or is
based upon an untrue statement or alleged untrue statement in or omission or
alleged omission from any of such documents in reliance upon and in conformity
with written information furnished to the Company by any Purchaser through Banc
of America specifically for use therein, it being understood and agreed that the
only such information consists of the information described as such in
subsection (b) below.

(b) Each Purchaser will severally and not jointly indemnify and hold harmless
the Company and the Guarantors, their directors and officers and each person, if
any, who controls the Company or the Guarantors within the meaning of Section 15
of the Securities Act, against any losses, claims, damages or liabilities to
which the Company or the Guarantors, as the case may be, may become subject,
under the Securities Act or the Exchange Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon any untrue statement or alleged untrue statement of any
material fact contained in the Preliminary Offering Circular or the Final
Offering Circular, in each case as amended or supplemented, or any Issuer Free
Writing Communication or arise out of or are based upon the omission or the
alleged omission to state therein a material fact necessary in order to make the
statements therein, in the light of the circumstances under which they were
made, not misleading, in each case to the extent, but only to the extent, that
such untrue statement or alleged untrue statement or omission or alleged
omission was made in reliance upon and in conformity with written information
furnished to the Company by such Purchaser through Banc of America specifically
for use therein, and will reimburse any legal or other expenses reasonably
incurred by the Company or the Guarantors in connection with investigating or
defending any such loss, claim, damage, liability or action as such expenses are
incurred, it being understood and agreed that the only such information
furnished by any Purchaser consists of the following information in the
Preliminary Offering Circular and the Final Offering Circular furnished on
behalf of each Purchaser: under the caption “Plan of Distribution” paragraphs 5,
8 and 9; provided, however, that the Purchasers shall not be liable for any
losses, claims, damages or liabilities arising out of or based upon the
Company’s or the Guarantors’ failure to perform their obligations under
Section 5(a) of this Agreement.

(c)  Promptly after receipt by an indemnified party under this Section of notice
of the commencement of any action, such indemnified party will, if a claim in
respect thereof is to be made against the indemnifying party under subsection
(a) or (b) above, notify the indemnifying party of the commencement thereof; but
the failure to notify the indemnifying party shall not relieve it from any
liability that it may

15

--------------------------------------------------------------------------------

have under subsection (a) or (b) above except to the extent that it has been
materially prejudiced (through the forfeiture of substantive rights or defenses)
by such failure; and provided further that the failure to notify the
indemnifying party shall not relieve it from any liability that it may have to
an indemnified party otherwise than under subsection (a) or (b) above. In case
any such action is brought against any indemnified party and it notifies the
indemnifying party of the commencement thereof, the indemnifying party will be
entitled to participate therein and, to the extent that it may wish, jointly
with any other indemnifying party similarly notified, to assume the defense
thereof, with counsel reasonably satisfactory to such indemnified party (who
shall not, except with the consent of the indemnified party, be counsel to the
indemnifying party), and after notice from the indemnifying party to such
indemnified party of its election so to assume the defense thereof, the
indemnifying party will not be liable to such indemnified party under this
Section for any legal or other expenses subsequently incurred by such
indemnified party in connection with the defense thereof other than reasonable
costs of investigation. No indemnifying party shall, without the prior written
consent of the indemnified party, effect any settlement of any pending or
threatened action in respect of which any indemnified party is or could have
been a party and indemnity could have been sought hereunder by such indemnified
party unless such settlement (i) includes an unconditional release of such
indemnified party from all liability on any claims that are the subject matter
of such action and (ii) does not include a statement as to or an admission of
fault, culpability or failure to act by or on behalf of any indemnified party.
No indemnifying party shall be liable for any settlement or compromise of, or
consent to the entry of judgment with respect to, any such action or claim
effected without its consent, unless such indemnifying party has failed, upon
request by the indemnified party pursuant to this Section 8, to reimburse the
indemnified party for legal expenses due pursuant to this Section 8 within
thirty days of such request.

(d)  If the indemnification provided for in this Section is unavailable or
insufficient to hold harmless an indemnified party under subsection (a) or
(b) above, then each indemnifying party shall contribute to the amount paid or
payable by such indemnified party as a result of the losses, claims, damages or
liabilities referred to in subsection (a) or (b) above (i) in such proportion as
is appropriate to reflect the relative benefits received by the Company and the
Guarantors on the one hand and the Purchasers on the other from the offering of
the Offered Securities or (ii) if the allocation provided by clause (i) above is
not permitted by applicable law, in such proportion as is appropriate to reflect
not only the relative benefits referred to in clause (i) above but also the
relative fault of the Company and the Guarantors on the one hand and the
Purchasers on the other in connection with the statements or omissions which
resulted in such losses, claims, damages or liabilities as well as any other
relevant equitable considerations. The relative benefits received by the Company
and the Guarantors on the one hand and the Purchasers on the other shall be
deemed to be in the same proportion as the total net proceeds from the offering
(before deducting expenses) received by the Company compared to the total
discounts and commissions received by the Purchasers from the Company under this
Agreement. The relative fault shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Company or the Purchasers and the parties’ relative intent,
knowledge, access to information and opportunity to correct or prevent such
untrue statement or omission. The amount paid by an indemnified party as a
result of the losses, claims, damages or liabilities referred to in the first
sentence of this subsection (d) shall be deemed to include any legal or other
expenses reasonably incurred by such indemnified party in connection with
investigating or defending any action or claim which is the subject of this
subsection (d). Notwithstanding the provisions of this subsection (d), no
Purchaser shall be required to contribute any amount in excess of the amount by
which the total price at which the Offered Securities purchased by it were
resold exceeds the amount of any damages which such Purchaser has otherwise been
required to pay by reason of such untrue or alleged untrue statement or omission
or alleged omission. The Purchasers’ obligations in this subsection (d) to
contribute are several in proportion to their respective purchase obligations
and not joint.

(e)  The obligations of the Company and the Guarantors under this Section shall
be in addition to any liability which the Company or the Guarantors may
otherwise have and shall extend, upon the same terms and conditions, to each
person, if any, who controls any Purchaser within the meaning of the Securities
Act or the Exchange Act; and the obligations of the Purchasers under this
Section shall be in

16

--------------------------------------------------------------------------------

addition to any liability which the respective Purchasers may otherwise have and
shall extend, upon the same terms and conditions, to each person, if any, who
controls the Company or the Guarantors within the meaning of the Securities Act
or the Exchange Act.

9. Default of Purchasers. If any Purchaser or Purchasers default in their
obligations to purchase—Offered Securities hereunder and the aggregate principal
amount of Offered Securities that such defaulting Purchaser or Purchasers agreed
but failed to purchase does not exceed 10% of the total—principal amount—of
Offered Securities, Banc of America and Credit Suisse may make arrangements
satisfactory to the Company for the purchase of such Offered Securities by other
persons, including any of the Purchasers, but if no such arrangements are made
by the Closing Date, the non-defaulting Purchasers shall be obligated severally,
in proportion to their respective commitments hereunder, to purchase the Offered
Securities that such defaulting Purchasers agreed but failed to purchase. If any
Purchaser or Purchasers so default and the aggregate—principal amount of Offered
Securities with respect to which such default or defaults occur exceeds 10% of
the total principal amount of Offered Securities and arrangements satisfactory
to Banc of America and Credit Suisse and the Company for the purchase of such
Offered Securities by other persons are not made within 36 hours after such
default, this Agreement will terminate without liability on the part of any
non-defaulting Purchaser or the Company, except as provided in Section 10. As
used in this Agreement, the term “Purchaser” includes any person substituted for
a Purchaser under this Section. Nothing herein will relieve a defaulting
Purchaser from liability for its default.

10. Survival of Certain Representations and Obligations. The respective
indemnities, agreements, representations, warranties and other statements of the
Company or its officers and of the Purchasers set forth in or made pursuant to
this Agreement will remain in full force and effect, regardless of any
investigation, or statement as to the results thereof, made by or on behalf of
any Purchaser, the Company or any of their respective representatives, officers
or directors or any controlling person, and will survive delivery of and payment
for the Offered Securities. If this Agreement is terminated pursuant to
Section 9 or if for any reason the purchase of the Offered Securities by the
Purchasers is not consummated, the Company shall remain responsible for the
expenses to be paid or reimbursed by it pursuant to Section 5 and the respective
obligations of the Company and the Purchasers pursuant to Section 8 shall remain
in effect. If the purchase of the Offered Securities by the Purchasers is not
consummated for any reason other than solely because of the termination of this
Agreement pursuant to Section 9 or the occurrence of any event specified in
clause (iii), (iv), (vi), (vii) or (viii) of Section 7(c), the Company will
reimburse the Purchasers for all out-of-pocket expenses (including reasonable
fees and disbursements of counsel) reasonably incurred by them in connection
with the offering of the Offered Securities.

11. Notices. All communications hereunder will be in writing and, if sent to the
Purchasers will be mailed, delivered or telegraphed and confirmed to the
Purchasers, c/o Banc of America Securities LLC, Nine West 57th Street, New York,
NY 10019, Attention: Legal Department, or, if sent to the Company, will be
mailed, delivered or telegraphed and confirmed to it at 1301 East 9th Street,
Suite 3710, Cleveland, OH 44114, Attention: Chief Financial Officer; provided,
however, that any notice to a Purchaser pursuant to Section 8 will be mailed,
delivered or telegraphed and confirmed to such Purchaser.

12. Successors. This Agreement will inure to the benefit of and be binding upon
the parties hereto and their respective successors and the persons referred to
