(a) Representations and Warranties. All representations and warranties and other statements herein by the Seller are, at and as of the business day preceding the Closing Date (the “Instruction Date”), true and correct in all material respects.

(b) No Adverse Change. Prior to the Instruction Date, there shall not have occurred any change, or any development involving a prospective change, in the condition, financial or otherwise, or in the earnings, business or operations of the Company and its subsidiaries, taken as a whole, from that set forth in the Company’s most recent annual report or subsequent public information releases issued prior to the date hereof that, in the reasonable judgment of the Managers and after consultation with the

7

Seller to the extent such consultation is practicable, is material and adverse and makes it impracticable to conduct the placement of the Securities in the manner contemplated herein.

(c) Opinion. There shall have been delivered to the Managers opinions from Sullivan & Cromwell LLP, Linklaters Loesch and Kromann Reumert in the forms attached as Appendices I, II and III hereto, respectively.

(d) Company Buyback.

     (i) The Company and the Seller shall have signed the Sale and Purchase Agreement, dated as of the date hereof, in respect of the purchase of 18,084,363 Shares by the Company from the Seller (the “Sale and Purchase Agreement”); and

     (ii) the Company shall have issued prior to 12:00 noon (London time) on the Instruction Date its settlement instructions to Danske Bank A/S (“Danske Bank”) in respect of the purchase of 18,084,363 Shares from the Seller pursuant to the Sale and Purchase Agreement in the form set forth in Schedule 5 thereto, which instructions shall become irrevocable upon Danske Bank’s receipt of written confirmation from each of the Managers of its delivery instructions with respect to the Securities in the form attached as Appendix IV hereto.

     The Managers in their sole discretion may waive any of the foregoing conditions. If any condition to the Managers’ obligations has not been satisfied prior to the Instruction Date, the Managers may elect, in their sole discretion and after consultation with the Seller to the extent such consultation is practicable, to terminate this Agreement. Sections 7, 9, 13, 14, 15, 16 and 17 shall survive any such termination.

Indemnity

9. (a) Indemnity. The Seller will indemnify and hold harmless the Managers against any losses, claims, damages or liabilities (“Losses”) to which the Managers may become subject insofar as such Losses (or actions in respect thereof) relate to or arise out of any breach or alleged breach of the representations and warranties, covenants or other undertakings of the Seller in this Agreement, other than any Losses that result from the Managers’ bad faith or gross negligence; and, subject to the provisions of sub-Section (c) of this Section 9, the Seller agrees to reimburse the Managers for any legal or other expenses reasonably incurred by the Managers in connection with investigating or defending any such action or claim as such expenses are incurred.

(b) Scope. (i) The obligations of the Seller under this Section 9 shall be in addition to any liability that the Seller may otherwise have and shall extend, upon the same terms and conditions, to the directors, officers, employees and controlling persons within the meaning of the Securities Act, as the

8

case may be, of the Managers and each of its affiliates within the meaning of the Securities Act (and shall include the partners of any such affiliate) (each, an “Indemnified Person”).

     (ii) The indemnification obligations of the Seller set forth in this Section 9 shall survive termination of this Agreement.

     (iii) The aggregate liability of the Seller pursuant to the indemnification obligations of the Seller set forth in this Section 9 shall be limited to DKK 9,679,848,418.50.

(c) Indemnification Procedures. Each Indemnified Person shall give notice as promptly as reasonably practicable to the Seller of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify the Seller shall not relieve the Seller from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. The Seller shall be entitled to assume conduct of the defense of any such action by notice to the Indemnified Person with counsel satisfactory to such Indemnified Person (which shall not, except with the consent of such Indemnified Person, be counsel to the Seller). The Seller shall not be liable to the Indemnified Person under sub-Section (a) of this Section 9 for any fees or expenses of counsel to the Indemnified Person in connection with the defense of any such action incurred after the date upon which the Seller gives notice of its election to assume the conduct of such defense but shall remain liable for any other Losses incurred by that Indemnified Person arising out of or in connection with any such action. In no event shall the Seller be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from its own counsel for all Indemnified Persons in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. The Seller shall not, without the prior written consent of the Indemnified Persons, settle or compromise or consent to the entry of any judgement with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 9 (whether or not the Indemnified Persons are actual or potential parties thereto), unless such settlement, compromise, consent or judgment (i) includes an unconditional release of each Indemnified Person from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(d) Contribution. If the indemnification provided for in this Section 9 is unavailable to an Indemnified Person in respect of any Losses referred to herein, then the Seller, in lieu of indemnifying such Indemnified Person, shall contribute to the amount paid or payable by such Indemnified Person as a result of such Losses (i) in such proportion as is appropriate to reflect the relative benefits received by the Seller on the one hand and the Managers on the other hand from the offering of the 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 Seller and the Managers in connection with the omission, breach of securities laws, misrepresentation or breach of warranty or other obligation under this Agreement which resulted in

9

such Losses, as well as any other relevant equitable considerations. The relative benefits received by the Seller and the Managers shall be deemed to be in the same proportion as the total net proceeds from the offering received by the Seller, and the total commissions received by the Managers, bear to the aggregate Purchase Price of the Securities sold pursuant to this Agreement.

Default by One or More of the Managers

10. (a) If one or more of the Managers shall fail on the Closing Date to procure investors for or purchase the Securities which it or they are obligated to procure investors for or purchase under this Agreement (the “Defaulted Securities”), the Managers shall have the right, within 24 hours thereafter, to make arrangements for the non-defaulting Manager(s) to place or purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth. If, however, within such 24-hour period the Managers shall not have completed such arrangements, or after giving effect to such arrangements there shall have remained Defaulted Securities to be placed or purchased, then:

     (i) In case of default by one Manager, each of the non-defaulting Managers shall be obligated, severally and not jointly, to purchase the full amount of the remaining Defaulted Securities at the Purchase Price in the proportions that its underwriting obligations hereunder bear to the underwriting obligations of the other non-defaulting Manager or Managers; provided, however, that the sum of (1) the aggregate number of Default Securities to be so purchased by the non-defaulting Managers, (2) the aggregate number of Securities which the Managers (including the defaulting Manager or Managers) agree to purchase from the Seller pursuant to sub-Section 2(a) of this Agreement and (3) the aggregate number of Shares otherwise owned by the Managers (including the defaulting Manager or Managers), in each case as of the Closing Date, shall not be greater than the number of Shares corresponding to 29% of the Company’s issued share capital as of the Closing Date in respect of all of the Managers (including the defaulting Manager or Managers) or 9.5% of the Company’s issued share capital as of the Closing Date in respect of each Manager (including the defaulting Manager or Managers).

     (ii) In case of default by Managers whose aggregate underwriting commitment is more than 50% of the Securities, this Section 10(a) shall terminate (without liability on the part of the non-defaulting Manager or Managers).

(b) No action taken pursuant to this Section 10 shall relieve any defaulting Manager from liability in respect of its default and, for the avoidance of doubt, each non-defaulting Manager shall be entitled to claim against each defaulting Manager in respect of such defaulting Manager’s default.

(c) In the event of any such default which does not result in a termination of this Agreement, either (i) the non-defaulting Managers or (ii) the Seller shall have the right to postpone the Closing Date for a period not exceeding seven days in order to effect any required changes in any documents or arrangements. As used herein, the term “Manager” includes any person substituted for a Manager under this Section 10.

10

Termination

11. This Agreement shall be subject to termination in the sole discretion of the Managers, and after consultation with the Seller to the extent such consultation is practicable, by notice given to the Seller prior to the Instruction Date, if at any time prior to such time (i) trading in the Shares shall have been suspended by the Copenhagen Stock Exchange or the New York Stock Exchange or trading in securities generally on either such exchange shall have been suspended or limited or minimum prices shall have been established on either such exchange; (ii) a banking moratorium shall have been declared by U.S. federal, New York state or Danish authorities; or (iii) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States or Denmark of a national emergency or war or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of the Managers, impractical or inadvisable to proceed with the offering or delivery of the Securities.

No Disclosure

12. Following the execution of this Agreement and prior to the Closing Date, except as may be required by applicable law or regulation, the transactions contemplated by this Agreement may not publicly be disclosed to any third party (other than to the Company and professional advisors to the Seller, the Company and the Managers) or otherwise publicly referred to unless the Seller and the Managers otherwise agree, provided that, for the avoidance of doubt, nothing in this Section 12 shall prevent the Managers from disclosing (in a manner consistent with the Managers’ undertakings set forth in Section 4 hereof) the transactions contemplated by this Agreement to potential investors to the extent such disclosure is appropriate in connection with the offering and placement of the Securities.

Guarantee

13. (a) Ameritech Corporation, a Delaware corporation (the “Guarantor”), hereby fully, unconditionally and irrevocably guarantees (the “Guarantee”) the performance of all of the obligations of the Seller under this Agreement, including the due and punctual payment by the Seller of any amounts payable under this Agreement and the satisfaction of each of the representations and warranties, indemnities, covenants and agreements of the Seller (the “Guaranteed Obligations”); provided, however, that each Manager agrees that it will make no claim under such Guarantee unless:

     (i) the aggregate amount of cash and cash equivalents held by the Seller is equal to less than €1 billion (as documented in form reasonably satisfactory to the Managers) and the amount of the claim exceeds the amount of cash and cash equivalents held by the Seller at the time of such claim; or

     (ii) the Seller has commenced (or third parties have commenced in respect of it) any proceeding for liquidation, dissolution or similar proceeding; or

     (iii) regardless of the amount of the claim, a demand for payment has been made on the Seller that the Seller has failed to pay within 30 days.

11

     In case of the failure of the Seller promptly to pay any amounts or to make whole the Managers for any of its obligations under this Agreement, the Guarantor hereby agrees to cause the payment of such amounts to be made promptly when and as such amounts become due and payable and as if such amounts were paid by the Seller or to promptly make whole the Managers for such obligations. Subject to the first sentence of this Section 13, the Guarantor hereby agrees that its obligations hereunder will be absolute and unconditional, irrespective of, and will be unaffected, to the fullest extent permitted by applicable law, by any act, omission, matter or thing which, but for this Section 13, might operate to release or otherwise exonerate in whole or in part the Guarantor from such obligations, or otherwise reduce, limit or affect such obligations, including:

     (i) any amendment to or variation of this Agreement or of any other document referred to herein;

     (ii) any time, indulgence, waiver or consent at any time given to the Seller or any other person;

     (iii) any compromise or release of, or abstention from obtaining, perfecting or enforcing in whole or in part any security or other right or remedy whatsoever against the Seller or any other person;

     (iv) any legal limitation, disability, incapacity or other circumstance relating to the Seller or any other person;

     (v) any irregularity, unenforceability or invalidity of any of the obligations of the Seller pursuant to this Agreement; or

     (vi) the dissolution, amalgamation, reconstruction or insolvency of the Seller.

     The Guarantor covenants that its obligations hereunder will not be discharged except by complete performance by the Seller of its obligations under this Agreement, including complete payment of the amounts due by the Seller hereunder. Notwithstanding the foregoing, the Managers agree to give the Seller notice of any claim under this Agreement (unless such party has been dissolved or liquidated) prior to making any demand under this Section 13 in respect of the Guaranteed Obligations. In the event that any payment to the Managers in respect of any amounts due by the Seller under this Agreement is rescinded or must otherwise be returned for any reason whatsoever, the Guarantor will remain liable for such amounts to the extent provided herein as if such amounts had not been paid. The aggregate amount to be paid under this Section 13 by the Guarantor in respect of a particular Guaranteed Obligation shall be net of any prior payment to the Managers by the Seller in respect of such Guaranteed Obligation.

(b) Notwithstanding anything to the contrary in this Section 13:

     (i) the requirements and waivers of the Guarantor set forth above in sub-Section 13(a) shall not operate to waive, affect or impair (x) any of the rights of the Seller enumerated in this Agreement, including but not limited to any right to receive notice, (y) any right of the Seller to assert any defense

12

otherwise applicable to any of the Guaranteed Obligations or (z) any right of the Guarantor to receive notice under this Agreement;

     (ii) the Guaranteed Obligations shall be determined in accordance with the provisions of this Agreement;

Ladies and Gentlemen:

In connection with the several purchases procured or made today by you (the “Managers”) pursuant to the Accelerated Bookbuilt Offering Agreement (the “ABO Agreement”), dated June 9, 2004, between Ameritech Luxembourg S.à.r.l, a limited liability company organized under the laws of the Grand Duchy of Luxembourg (the “Selling Shareholder”), and Ameritech Corporation, a Delaware Corporation (the “Guarantor”), on the one hand, and the Managers, on the other hand, of 51,351,981 ordinary shares, par value DKK 5 per share (the “Shares”), of TDC A/S (the “Company”), we, as United States counsel for the Selling Shareholder, have examined the ABO Agreement, the Sale and Purchase Agreement, dated June 9, 2004, between the Selling Shareholder and the Guarantor, on the one hand,

A-1

and the Company, on the other hand (the “Sale and Purchase Agreement”), and such corporate records, certificates and other documents, and such questions of U.S. Federal law, as we have considered necessary or appropriate for the purposes of this opinion. Upon the basis of such examination, it is our opinion that no registration of the Shares under the U.S. Securities Act of 1933, as amended (the “Securities Act”), is required for (1) the offer by the Managers, and the initial sale and delivery by the Selling Shareholder to the investors procured by the Managers, of the Shares and (2) the sale and delivery of the Shares by the Selling Shareholder to the Managers and the offer and initial resale of such Shares by the Managers, in each case in the manner contemplated by the ABO Agreement. We express no opinion, however, as to when and under what circumstances the Shares may subsequently be reoffered or resold.

The foregoing opinion is limited to the Federal laws of the United States and we are expressing no opinion as to the effect of the laws of any other jurisdiction.

In connection with our opinion set forth above, with your approval, we have relied upon the representations, warranties, agreements and undertakings made by the Selling Shareholder and the Managers in the ABO Agreement and by the Selling Shareholder and the Company in the Sale and Purchase Agreement with respect to the manner of offering and selling the Shares, the absence of any directed selling efforts (as defined in Regulation S under the Securities Act) and the absence of any form of general advertising or general solicitation in the United States in connection with the offer and sale of the Shares and with respect to certain other matters. In addition, we have assumed that you will offer and sell the Shares only in accordance with the ABO Agreement.

Also, with your approval, we have relied as to certain matters on information obtained from officers of the Company, officials of the Selling Shareholder and other sources believed by us to be responsible, and we have assumed that the signatures on all documents examined by us are genuine, assumptions which we have not independently verified.

Very truly yours,

A-2

Dear Sirs,

Ameritech Luxembourg S.à.r.l.

1 Introduction

We have acted as special Luxembourg counsel to Ameritech Luxembourg S.à.r.l., a Luxembourg limited liability company (société à responsabilité limitée) (the “Company”), in connection with the sale by the Company of the Securities (as defined below) and the TDC Shares (as defined below). This Opinion is being rendered pursuant to Section 8(c) of the agreement, dated June 9, 2004, executed by Citigroup Global Markets Limited, Goldman Sachs International, ABN AMRO Bank N.V. and NM Rothschild & Sons Limited (each trading as ABN AMRO Rothschild), Deutsche Bank AG London, J.P.

A-1

“Sale and Purchase Agreement”) in connection with TDC’s purchase from the Company of 18,084,363 ordinary shares in TDC (the “TDC Shares”). Capitalised terms used in this legal opinion (the “Opinion”) not otherwise defined herein shall have the same meaning when used herein as in the Agreement.

For the purpose of rendering this Opinion, we have examined originals or certified copies of the following documents:

1.	a copy of the Agreement dated June 9, 2004;
2.	a copy of the Sale and Purchase Agreement dated June 9, 2004;
3.	a copy of the restated Articles of Association of the Company at May 2, 2002, these Articles of Association not having been amended since that date based on a check carried out by us on the date of this opinion letter in Luxembourg records open to public;
4.	a copy of Managers Resolutions of the Company adopted on June 9, 2004 approving and authorising the sale of the Securities and the TDC Shares;
5.	an extract dated May 25, 2004 from the Luxembourg Register of Commerce and Companies concerning the Company;
6.	a non-bankruptcy certificate dated May 10, 2004 delivered by the Luxembourg District Court concerning the Company;

and such corporate documents and records of the Company and other certificates, documents, records and papers as we have deemed relevant and necessary in order to give the Opinion hereinafter set forth.

2 Luxembourg Law

This opinion speaks as of its date and is confined to and is solely given on the basis of the laws of Luxembourg as applied by the Luxembourg Courts, published and presently in effect. We undertake no responsibility to notify any addressee of this opinion of any change in the laws of Luxembourg or their construction or application after the date of this opinion.

In this opinion, Luxembourg legal concepts are expressed in English terms and not in their original French terms. The concepts concerned may not be identical to the concepts described by the same English terms as they exist under the laws of other jurisdictions. This opinion may, therefore, only be relied upon under the express condition that it is given under Luxembourg law and case law and that any issues of interpretation arising hereunder will be governed by Luxembourg law and be brought before a Luxembourg Court.

We express no opinion as to any laws other than the laws of Luxembourg and we have assumed that there is nothing in any other law that affects our opinion.

3 Assumptions

For the purpose of this opinion, we have assumed:

A-2

3.1	that the Agreement and the Sale and Purchase Agreement have been, or will be, duly authorised, executed and delivered by or on behalf of all relevant parties (other than the Company) and are, or will be, legal, valid, binding and enforceable against all relevant parties in accordance with their respective terms under all other relevant laws (other than the laws of Luxembourg);
3.2	that copy documents provided to us are true copies of, or in the final forms of, the originals;
3.3	the genuineness of all signatures;
3.4	that the Company derives a commercial or financial benefit from the Agreement to which it is a party; that the restated Articles of Association of the Company dated May 2, 2002 have not been amended and remain in full force and effect without modification (this assumption is based on a check carried out by us on the date of this opinion letter in Luxembourg records open to public and a confirmation hereof that we have obtained from the Company);
3.5	that the minutes of the Board of Directors of the Company dated June 9, 2004 are true records of the proceedings described in them and remain in full force and effect without modification (this assumption is based on a confirmation hereof that we have obtained from the Company);
3.6	the power, authority and legal right of all parties or other persons concerned under all relevant laws and regulations (other than the Company under the laws of Luxembourg) to enter into, execute and perform their respective obligations under the Agreement and the Sale and Purchase Agreement and to act otherwise in the present context; and
3.7	that the Agreement has the same meaning and effect under the laws by which it is expressed to be governed as it would have if it were interpreted under Luxembourg law by a Luxembourg court and there are no provisions of those laws which would affect this opinion.

4 Opinion

Based on the documents referred to in paragraph 1 above, subject to the assumptions made in paragraph 3 and to the qualifications made in paragraph 5 and to any matters or documents not disclosed to us , we are of the following opinion:

4.1 The Company has been duly organized and is validly existing as a corporation under the laws of the Grand Duchy of Luxembourg, with corporate power and authority to enter into and perform the Agreement and the Sale and Purchase Agreement in accordance with their terms.

A-3

4.2	The Company has full power under its constitutive documents and applicable law, and all authorisations, approvals, consents and licenses required by it have been unconditionally obtained and are in full force and effect, to permit it to enter into and perform the Agreement and the Sale and Purchase Agreement and the Agreement and the Sale and Purchase Agreement have been duly authorized, executed and delivered by the Company and are valid and binding agreements enforceable in accordance with their terms.
4.3	The sale and delivery of the Securities and the TDC Shares and the compliance by the Company with all other provisions of the Agreement and the Sale and Purchase Agreement, as well as the consummation of the transactions contemplated in the Agreement and the Sale and Purchase Agreement, will not conflict with, result in a breach or violation of or constitute a default under the Articles of Association of the Company or Luxembourg law.
4.4	No authorization, approval, consent, order, designation, declaration, license of or filing by or with any regulatory, administrative or other governmental body or court of the Grand Duchy of Luxembourg is required in connection with the execution and delivery of the Agreement and the Sale and Purchase Agreement.
4.5	No VAT or stamp or other issuance or transfer taxes or duties are payable in connection with the sale and delivery of the Securities and the TDC Shares in the manner contemplated in the Agreement and the Sale and Purchase Agreement or the consummation of any other transaction contemplated in the Agreement and the Sale and Purchase Agreement in connection with the sale of such Securities and such TDC Shares.

5 Qualifications

5.1	This opinion is subject to any limitations arising from bankruptcy, insolvency, liquidation, moratorium, reorganisation and other laws of general application relating to or affecting the rights of creditors.
5.2	Other than the opinion expressed in paragraph 4.5, we do not express any opinion as to any taxation matters.
5.3	The admissibility as evidence of the Agreement and the Sale and Purchase Agreement before a Luxembourg Court or public authority (“autorit” constituée”) to which the Agreement and/or the Sale and Purchase Agreement are produced may require that the Agreement/the Sale and Purchase Agreement come with a complete or partial translation in the French or German language and be subjected to the payment of a registration tax.
5.4	We express no opinion on any documents referred to in the Agreement and the Sale and Purchase Agreement, but not specifically examined by us and as to the accuracy of any warranties and representations given or made by the Company (expressed or impliedly) save and insofar as the matters warranted are the subject matter of specific opinions in this letter.

A-4

5.5	The enforcement in Luxembourg of the Agreement and the Sale and Purchase Agreement may be limited by general principles of equity and good faith and specific performance and injunction remedies may not be available in Luxembourg. Further, claims may be barred by limitation period rules and set off and counter-claims rules.
5.6	Limitation of liability clauses may be unenforceable in case of gross negligence or wilfull misconduct.

6	Reliance
	This opinion is solely for your benefit and solely for the purpose of the Agreement and the Sale and Purchase Agreement. It is not to be transmitted to anyone else nor is it to be relied upon by anyone else or for any other purpose or quoted or referred to in any public document or filed with anyone without our written consent.

Yours sincerely,

Linklaters Loesch
